Description

TECHNICAL FIELD

The present disclosure relates to a laundry treating apparatus. More specifically, the present disclosure relates to a laundry treating apparatus that may remove foreign substances such as dust by applying a physical force to hung laundry.

BACKGROUND

A laundry treating apparatus is an apparatus developed to wash and dry laundry at home and in a laundry shop and to remove wrinkles from the laundry. Concepts categorized as the laundry treating apparatus include a washing machine that washes the laundry, a dryer that dries the laundry, a washer/dryer with both a washing function and a drying function, a laundry manager that refreshes the laundry, a steamer that removes the wrinkles from the laundry, and the like.

Recently, a laundry treating apparatus corresponding to the laundry manager that allows the laundry to be kept pleasant and clean without having to soak the laundry in water and wash the laundry with detergent has appeared.

A laundry treating apparatus that performs a refreshing cycle by supplying either high-temperature air or steam to the laundry to deodorize the laundry, dry the laundry, and remove the wrinkles from the laundry has appeared.

The laundry treating apparatus that may perform the refreshing cycle is able to oscillate the laundry while supplying hot air or steam to the laundry to remove fine dust or the foreign substances attached to the laundry. See Korean Patent No. 10-1285890

FIG. 1 shows a structure of oscillating laundry in an existing laundry treating apparatus.

A moving hanger M of the existing laundry treating apparatus includes a support bar 2 disposed in an accommodating space where the laundry is hung, a hanger 3 that extends downward from the support bar 2 such that the laundry may be hung, and a driver 5 that may oscillate the support bar 2.

The driver 5 may include a motor 51 fixed on the support bar 2 to rotate a rotation shaft 53, and may include an eccentric shaft 55 coupled to the rotation shaft 53 to rotate along a trajectory larger than a rotational diameter of the rotation shaft 53.

The support bar 2 may have a reciprocation inducer 4 installed at a center to accommodate the eccentric shaft therein and receive power. The eccentric shaft 55 may move along the rotation of the rotation shaft 53 while coupled to the reciprocation inducer 4 to reciprocate the reciprocation inducer 4 in a left and right direction.

The eccentric shaft 55 may rotate by being coupled to a distal end of a connecting shaft 52 coupled to a distal end of the rotation shaft 53.

FIG. 2 shows a structure in which a support bar moves in a left and right direction.

The reciprocation inducer 4 may include a slit 41 defined in a thickness direction of the support bar 2 to accommodate the eccentric shaft 55 therein.

Referring to (a) in FIG. 2, the eccentric shaft 55 may be inserted into the slit 41 and rotate along an arc trajectory with a radius of a distance R from the rotation shaft 53.

The support bar 2 may be fixed so as to be movable only in the left and right direction in the laundry treating apparatus and not move forward or rearward.

Referring to (b) in FIG. 2, when the eccentric shaft 55 rotates 90 degrees to the right, the slit 41 may move to the right by R together with the eccentric shaft 55 because of the rightward movement of the eccentric shaft 55 by R. As a result, the support bar 2 moves to the right.

In such manner, when the eccentric shaft 55 rotates 180 degrees to the left, the slit 41 will move to the left, and the support bar 2 will also move to the left.

When the rotation shaft 53 rotates once, the support bar 2 may reciprocate once in the left and right direction. Further, when the rotation shaft 53 rotates continuously, the support bar 2 reciprocates several times in the left and right direction.

As a result, the laundry hung on the hanger 3 extended from the support bar 2 oscillates in the left and right direction, so that the foreign substances or the dust may be removed.

However, because the support bar 2 reciprocates in the left and right direction in such existing laundry treating apparatus, an entirety of the laundry treating apparatus vibrates strongly because an inertial force is rapidly applied whenever the support bar 2 changes a moving direction thereof.

In particular, as the number of or a weight of the laundry pieces hung on the hanger 3 increases, a vibration amount thereof increases, so that stability of the laundry treating apparatus is also not able to be guaranteed.

In addition, in the existing laundry treating apparatus, the greater the vibration, the greater the noise generated, so that the noise is emitted every time the laundry treating apparatus is operated, and a use of the laundry treating apparatus is restricted at night or the like.

FIG. 3 shows a state in which a driver output of an existing laundry treating apparatus is lost.

In addition, the existing laundry treating apparatus is not able to utilize a maximum output of the driver 5 because the vibration generated by the reciprocating movement of the support bar 2 exceeds a reference value even when the driver 5 is able to provide sufficient output.

In addition, the moving hanger in the left-right reciprocating movement scheme as in the existing laundry treating apparatus is not able to fully receive a rotational force of a driving force of the driver 5.

Specifically, the slit 41 of the support bar 2 of the moving hanger is able to transmit a force of the eccentric shaft 55 rotating left or right to the laundry, but is not able to transmit a force of the eccentric shaft 55 rotating rearward or forward to the laundry at all and dissipates the force.

Specifically, when the eccentric shaft 55 is disposed at locations I and III, the slit 41 may receive the force of moving right and left as it is.

However, when moving from the location I to the location II, and from the location III to the location IV, the force transmitted by the eccentric shaft 55 to move the slit 41 left and right is drastically reduced.

This is because the force of the eccentric shaft 55 to move the slit 41 corresponds only to a cosine value for the rotation direction of the eccentric shaft 55, and therefore, when the eccentric shaft 55 is located at locations of 90 degrees and 270 degrees with respect to a rotation center, the power transmitted from the eccentric shaft 55 to the slit 41 corresponds to 0.

In other words, the driver 5 continuously transmits the power to the eccentric shaft 55, but the eccentric shaft 55 is only able to transmit a portion of the power to the slit 41, and at a specific point, is not able to transmit the power at all.

As a result, in the existing laundry treating apparatus, most of the power of the driver 5 is lost without being transmitted to the laundry. Therefore, the existing laundry treating apparatus has a problem that sufficient oscillating force is not transmitted to the laundry even though the driver 5 has the sufficient output to oscillate the laundry, or that the driver 5 has to be operated with excessive output to transmit the sufficient oscillating force to the laundry.

As a result, the existing laundry treating apparatus has a fundamental problem that the sufficient oscillating force is not transmitted to the laundry from the driver 5, and thus a performance of removing the foreign substances or the dust attached to the laundry is not excellent.

In addition, the existing laundry treating apparatus is not able to transmit a rotational force generated by the driver 5 to the support bar 2 as it is because the support bar 2 is disposed in a width direction and the hanger 3 is also fixed to the support bar 2.

FIG. 4 shows an outer appearance of a laundry treating apparatus 1 of the present disclosure.

Referring to (a) in FIG. 4, the laundry treating apparatus of the present disclosure may include a cabinet 10 forming the outer appearance thereof, and a door 11 pivotably coupled to the cabinet 10.

Referring to (b) in FIG. 4, an inner casing 20 having an accommodating space 21 for accommodating laundry therein may be disposed inside the cabinet 10. The inner casing 20 may include an opening 21 defined in a front surface thereof through which the laundry enters and exits, and the opening 21 may be shielded by the door 11.

The inner casing 20 may be made of a plastic resin-based material, and may be made of a reinforced plastic resin-based material that does not deform even when exposed to air at a temperature higher than a room temperature or heated air (hereinafter, hot air), steam, or moisture.

The inner casing 20 may have a height greater than a width. Accordingly, the laundry may be accommodated in the accommodating space 21 without being folded or crumpled.

A laundry treating apparatus 1 of the present disclosure may include a clothes hanger 900 that may hang the laundry in the accommodating space 21 of the inner casing 20.

The clothes hanger 900 may be disposed on a top surface of the inner casing 20 and may be seated on a hanger part 700 that hangs the laundry. The clothes hanger 900 may be detachably disposed on the hanger part 700.

When the laundry is hung on the hanger part 700, the laundry may be disposed in a state of suspending in air within the accommodating space 21.

The laundry treating apparatus of the present disclosure may further include a pressurizer 50 that may be coupled to an inner surface of the door 11 to fix the laundry.

The pressurizer 50 may include a pressurizing surface 522 disposed on the inner surface of the door 11 and a pressurizing panel 521 that may be pivotably coupled to the pressurizing surface 522 and may pressurize the laundry disposed on the pressurizing surface 522. The pressurizer 50 may mainly pressurize long laundry, such as bottoms, to remove wrinkles and may also create intended creases.

The laundry treating apparatus of the present disclosure may have a machine room 30 in which various apparatuses that may supply at least one of hot air and steam to the accommodating space 21 or may purify or dehumidify external air of the cabinet 10 are installed.

The machine room 30 may be disposed separately or partitioned from the inner casing 20, but may be in communication with the inner casing 20.

The machine room 30 may be disposed under the inner casing 20. Accordingly, when hot air and steam having a small specific gravity are supplied to the inner casing 20, hot air and steam may be naturally supplied to the laundry.

The machine room 30 may include a circulation duct that circulates air inside the inner casing 20, and a plurality of heat exchangers that are disposed on the circulation duct to cool and condense air and heat air.

The machine room 30 may be equipped with a heat pump system that includes a compressor that may be connected to the plurality of heat exchangers and may compress a refrigerant that cools or heats air.

In one example, the machine room 30 may also be equipped with a steam supply that may supply steam into the inner casing 20.

The steam supply may heat water to generate steam. As a result, the laundry accommodated inside the inner casing may be exposed to hot air and steam, so that deodorization, sterilization, and wrinkle removal may be performed.

A water tank 31 that supplies water to generate steam, and a drain tank 32 that collects condensed water from the circulation duct may be included in a front portion of the machine room 30.

The water tank 31 and the drain tank 32 may be detachably installed in the front portion of the machine room 30. Accordingly, even when the laundry treating apparatus of the present disclosure is not disposed near a water source or a drain hole, the user may detach and carry the water tank 31 and the drain tank 32 whenever necessary.

The water tank 31 and the drain tank 32 may be arranged in a parallel manner along a width direction of the machine room 30.

In addition, the machine room 30 may further include a drawer 33 that accommodates therein items or the like necessary for managing the laundry. The drawer 33 may be provided to be extendable from the machine room 30, and a space for accommodating the items such as an iron may be defined inside the drawer 33.

The seating base 60 may include a light-emitter that irradiates light into the inner casing 20, and the light-emitter may irradiate light toward an inner surface of the inner casing 20 to prevent glare.

In one example, the laundry treating apparatus of the present disclosure may further include a moving hanger 100 that shakes the clothes hanger 900 to remove foreign substances and dust from the laundry hung on the clothes hanger 900.

The moving hanger 100 may be provided to operate when at least one of hot air and steam is supplied to the laundry, thereby inducing the foreign substances attached to the laundry to be removed by hot air or steam.

The moving hanger 100 may be provided to reciprocate the clothes hanger 900 and remove the dust from the laundry.

FIG. 5 shows an embodiment of the moving hanger 100 of the laundry treating apparatus of the present disclosure.

The moving hanger 100 may include the clothes hanger 900 on which the laundry is hung, the hanger part 700 that mounts the clothes hanger 900 inside the inner casing 20, and a power transmitter 400 that supports the hanger part 700 inside the inner casing 20 and shakes the hanger part 700.

The power transmitter 400 may include a plurality of power transmitters arranged to be spaced apart from each other along a width direction of the inner casing 20, and each hanger part 700 may be coupled and fixed to a lower portion of each power transmitter 400.

The moving hanger 100 may include a displacement generator 300 that connects a driver 200 that transmits power to move or shake the power transmitter 400 with the power transmitter 400 to transmit power generated from the driver 200 to the power transmitter 400.

Specifically, the driver 200 may include a motor 210 that generates the power and a rotation shaft 240 that rotates by the motor 210.

The rotation shaft 240 may be disposed along the width direction of the inner casing 20, and one end thereof may be rotated by the motor 210 and the other end thereof may be coupled to a support base that is rotatably supported.

The power transmitter 400 may be disposed along a length direction of the rotation shaft 240 and may easily receive the power from the rotation shaft 240.

The displacement generator 300 may be coupled to the rotation shaft 240 and may receive the power from the rotation shaft 240 and transmit the power to the power transmitter 400.

The displacement generator 300 may rotate together with the rotation shaft 240, and may include displacement generators in a number corresponding to the number of power transmitters 400 that are respectively connected to the power transmitters 400.

In one example, when the rotation shaft 240 is exposed inside the inner casing 20, the laundry may come into contact with the rotation shaft 240 and the laundry may be damaged, and there may be a risk of injury, electric shock, or the like to the user when the user grips the rotation shaft 240.

Therefore, it is preferable that an entirety of the rotation shaft 240 is blocked from being exposed inside the inner casing 20, or at least a lower end of the rotation shaft 240 is blocked from being exposed inside the inner casing 20.

To this end, the moving hanger 100 may further include a support 800 disposed at a lower end of the rotation shaft 240.

The support 800 may be formed as a metal plate disposed in the length direction of the rotation shaft 240 or the width direction of the inner casing 20, and may be fixed to and supported by a frame 12 disposed outside the inner casing 20 and inside the cabinet 10.

The rotation shaft 240 may be rotatable above the support 800, and the hanger part 700 and the clothes hanger 900 may be disposed under the support 800.

As a result, accidents such as the laundry being wrapped around the rotation shaft 240 may be prevented, and the user located below the support 800 may be prevented from gripping the rotation shaft 240.

In one example, the power transmitter 400 may be disposed to extend through the support 800 and may be disposed in a height direction of the inner casing 20.

The power transmitter 400 may have an upper portion disposed upward of the support 800 and adjacent to the rotation shaft 240 or the displacement generator 300 and a lower portion disposed downward of the support 800 and exposed to the accommodating space 21 of the inner casing 20.

The support 800 may be positioned upward of a top surface of the inner casing 20, and may support the rotation shaft 240 on the outside of the inner casing 20.

The driver 200 may allow the motor 210 to directly rotate the rotation shaft 240. However, to prevent the damage to the laundry by lowering an RPM at which the rotation shaft 240 rotates while utilizing a maximum output of the motor 210, the driver 200 may include a transmitter 230 that connects the motor 210 with the rotation shaft 240.

For example, the motor 210 may rotate a driving shaft 220 that may rotate in parallel with the rotation shaft 240, and the transmitter 230 may include a belt 233 coupled to the driving shaft 220, and a transmission pulley 232 that is spaced apart from the driving shaft 220, has a diameter larger than that of the driving shaft 220, and is connected to the belt 233.

The transmitter 230 may further include a power pulley 231 coupled to an outer circumferential surface of the driving shaft 220 to rotate the belt 233 to strengthen the connection between the belt 233 and the driving shaft 220.

The rotation shaft 240 may be coupled to a rotation center of the transmission pulley 232 and rotate together with the transmission pulley 232.

The motor 210 and the transmitter 230 may also be fixed to the support 800 and supported by the support 800. The support 800 may support a load of an entirety of the moving hanger 100.

The displacement generator 300 may receive the power from the rotation shaft 240 while being coupled to and rotating together with the rotation shaft 240. The displacement generator 300 may generate a location change (a displacement) that may move the power transmitter 400 from the rotational motion of the rotation shaft 240 that simply rotates at a fixed location.

For example, the displacement generator 300 may be formed in a disk shape that is coupled to the rotation shaft 240 and rotates, but may rotate while being coupled at an angle to a diameter direction of the rotation shaft 240 or may have an outer circumferential surface disposed at an angle to the diameter direction of the rotation shaft 240.

Accordingly, when the displacement generator 300 rotates in a direction 1, the outer surface circumferential of the displacement generator 300 may rotate around a virtual axis inclined with respect to the rotation shaft 240.

The power transmitter 400 may be in contact with the outer circumferential surface of the displacement generator 300 such that an installed inclination thereof may vary whenever the inclination of the outer circumferential surface of the displacement generator 300 varies based on the rotation shaft 240.

For example, the power transmitter 400 may rotatably support both side surfaces of the displacement generator 300, but have a fixed installation vertical level. Accordingly, when the displacement generator 300 rotates in the direction 1, the power transmitter 400 may reciprocally rotate in the left and right direction based on the rotation shaft 240. As a result, the hanger part 700 and the clothes hanger 900 coupled to the power transmitter 400 may also reciprocally rotate in the left and right direction based on the power transmitter 400. Accordingly, the laundry hung on the clothes hanger 900 may reciprocally rotate in the left and right direction to shake off the dust.

FIG. 6 shows an embodiment of the power transmitter and the displacement generator.

The power transmitter 400 may include a connector 440 that extends through the support 800 and is coupled to both side surfaces of the displacement generator 300.

The connector 440 may be supported so as to be rotatable in the left and right direction by the support bearing 460, but a location variation or an inclination change thereof in an upward or downward direction, in a forward or rearward direction, and the like may be prevented.

The displacement generator 300 may include a rotatable body 350 coupled to the rotation shaft 240, and a contact portion 360 disposed on an outer circumferential surface of the rotatable body 350 and in contact with the connector 440.

The rotatable body 350 may be formed in a cylindrical or disc shape, and may include a shaft coupling portion 351 constructed such that the rotation shaft 240 extends through an inner side thereof.

A diameter of the rotatable body 350 may be larger than that of the rotation shaft 240.

The connector 440 may rotate in the left and right direction while maintaining a vertical level thereof whenever an inclination of the contact portion 360 changes as both upper ends thereof come into contact with the contact portion 360.

FIG. 7 shows a detailed structure of the power transmitter and the displacement generator.

The rotation shaft 240 may include a shaft body 241 that rotates by the transmitter 230, and a shaft groove 242 in which a clip 370 disposed on the shaft body 241 and fixing the rotatable body 350 is seated.

A gap between the shaft grooves 242 may correspond to a thickness of the rotatable body 350.

The rotatable body 350 may include the shaft coupling portion 351 through which the rotation shaft 240 extends, and the shaft coupling portion 351 may include a reinforcing step 3511 having a circular inner circumferential surface, but protruding or recessed inwardly to reinforce a force of coupling with the rotation shaft 240.

The rotation shaft 240 may include a coupling step 243 that may be coupled with the reinforcing step 3511 at a location between the shaft grooves 242.

The contact portion 360 may include an accommodating groove 361 that is recessed along a circumference of an outer circumferential surface of the rotatable body 350.

The accommodating groove 361 may form a closed curve along the circumference of the rotatable body 350.

The connector 440 may include an penetrating body 441 penetrating through the support 800, and a gripping portion 442 extending from an upper portion of the penetrating body 441 to both side surfaces of the rotatable body 350.

The penetrating body 441 may be formed in a cylindrical or pipe shape such that the connector 440 may easily rotate in the left and right direction.

The gripping portion 442 may include a first gripping portion 4421 extending from the upper portion of the penetrating body 441 to one side surface of the rotatable body 350, and a second gripping portion 4422 extending from the upper portion of the penetrating body 441 to the other side surface of the rotatable body 350.

The first gripping portion 4421 and the second gripping portion 4422 may be disposed to extend from the penetrating body 441 to have the same height, and the rotation shaft 240 and the rotatable body 350 may be disposed therebetween.

The first gripping portion 4421 and the second gripping portion 4422 may extend from the penetrating body 441 to a vertical level corresponding to or higher than that of the rotation shaft 240.

In one example, when the first gripping portion 4421 and the second gripping portion 4422 are able to be in contact both surfaces of the contact portion 360, they may extend to a vertical level lower than that of the rotation shaft 240.

The gripping portion 442 may include a inserted protrusion 443 that may be inserted into the accommodating groove 361 and may be in contact with the accommodating groove 361.

The inserted protrusion 443 may have a width corresponding to a width of the accommodating groove 361, and may have any thickness as long as it is able to be in contact with both surfaces of the accommodating groove 361 when the rotatable body 350 rotates.

The inserted protrusion 443 may slide the accommodating groove 361 when the rotatable body 350 rotates.

The inserted protrusion 443 may rotate the gripping portion 442 around the support 800 based on an inclination of the accommodating groove 361.

The inserted protrusion 443 may protrude inwardly of the gripping portion 442 or toward the rotatable body 350, may be formed integrally with the gripping portion 442, and may be fixed by being coupled with the gripping portion 442.

The protrusions-to-be-inserted 443 may protrude from inner surfaces of the first gripping portion 4421 and the second gripping portion 4422, respectively, and the plurality of protrusions-to-be-inserted 443 may be disposed at a corresponding vertical level.

The auxiliary support 420 may be coupled to a lower portion of the penetrating body 441.

A screw thread 4411, which may be coupled to a support member 424 that may be fastened to the auxiliary support 420 and may support the auxiliary support 420, may be disposed at a lower portion of the penetrating body 441.

The penetrating body 441 may be rotatably supported by the support bearing 460 that is seated on the support 800.

The auxiliary support 420 may be disposed downward of the support bearing 460.

The auxiliary support 420 may include a first auxiliary body 4211 disposed parallel to the support 800 and through which the penetrating body 441 may extend, and a second auxiliary body 4212 extending downward from the first auxiliary body 4211 and to which the hanger part 700 may be coupled.

The hanger part 700 may include a coupling body 710 coupled to one surface of the second auxiliary body 4212 and the peg fixer 720 coupled to the other surface of the second auxiliary body 4212.

The second auxiliary body 4212 may include a seating body 423 on which the coupling body 710 and the peg fixer 720 are seated on at least one of one surface and the other surface thereof.

The coupling body 710 and the peg fixer 720 may be firmly coupled to the second auxiliary body 4212 as a fastening member passes therethrough.

The coupling body 710 may include, at an upper portion thereof, a ring-seating body 712 where a ring of the clothes hanger 900 is seated, and a first protruding rib 711 and a second protruding rib 714 that protrude from the upper portion of the coupling body 710 to prevent the ring-seating body 712 from deviating.

The coupling body 710 may include a fastening portion 713 allowing the fastening member to extend therethrough and to be seated therein.

FIG. 8 shows a change in a location of an accommodating groove when the rotatable body rotates.

The accommodating groove 361 may be defined obliquely in the outer circumferential surface of the rotatable body 350 and may be defined along the circumference of the rotatable body 350.

Accordingly, a rotation center of the accommodating groove 361 may be defined to be misaligned from the rotation shaft 240.

As a result, when the rotatable body 350 rotates, the location of the accommodating groove 361 may vary. Specifically, when the rotatable body 350 rotates, locations of both ends of a protruding ring 362 may vary from predetermined locations.

Referring to (a) in FIG. 8, in a top view of the rotatable body 350, when the rotatable body 350 rotates, at first, a left side of the accommodating groove 361 may be disposed at a front side and a right side thereof may be disposed at a rear side.

Referring to (b) in FIG. 8, when the rotatable body 350 rotates 180 degrees, the left side of the accommodating groove 361 may be disposed at the rear side and the right side thereof may be disposed at the front side.

Referring to (c) in FIG. 8, when the rotatable body 350 rotates 360 degrees, the accommodating groove 361 may return to an original location thereof.

When such process is repeated, both ends of the accommodating groove 361 may rotate in the left and right direction based on the rotatable body 350.

FIG. 9 shows operating states of the power transmitter and the displacement generator in a top view of the moving hanger.

• • (a) in FIG. 9 shows an arrangement of the power transmitter 400 and the accommodating groove 361 based on the rotatable body.

Although the accommodating groove 361 is defined along the circumference at an angle based on the rotatable body 350, there is a point where a rotation diameter of the rotatable body 350 and a rotation diameter of the accommodating groove 361 meet each other.

Therefore, when the accommodating groove 361 is located at the point at which the rotation diameter thereof meets the rotation diameter of the rotatable body 350, the accommodating groove 361 may be defined parallel to a diameter direction of the rotation shaft as shown in the first drawing.

Therefore, the inserted protrusion 443 that is inserted into the accommodating groove 361 may also be disposed parallel to the diameter direction of the rotation shaft 240, and the connector 440 may be disposed at a location corresponding to the diameter direction of the rotation shaft.

When the rotatable body 350 rotates 90 degrees, the accommodating groove 361 also rotates, and the accommodating groove 361 is defined to be inclined with the outer circumferential surface of the rotatable body 350. For example, as shown in the drawing, a front side of the accommodating groove 361 moves to a right side and a rear side thereof moves to a left side.

As a result, the inserted protrusion 443 inserted into the accommodating groove 361 also rotates correspondingly, so that the connector 440 may rotate counterclockwise.

When the rotatable body 350 rotates 180 degrees, the accommodating groove 361 rotates further, so that both side surfaces of the accommodating groove 361 are disposed parallel to the outer circumferential surface of the rotatable body 350. As a result, the inserted protrusion 443 inserted into the accommodating groove 361 also rotates correspondingly, so that the connector 440 may be disposed parallel to the diameter direction of the rotation shaft 240 even when slightly rotating clockwise.

When the rotatable body 350 rotates 270 degrees, the accommodating groove 361 rotates further, so that the accommodating groove 361 is defined to be inclined with respect to the outer circumferential surface of the rotatable body 350. For example, as shown in the drawing, the front side of the accommodating groove 361 moves to the left side and the rear side thereof moves to the right side.

As a result, the inserted protrusion 443 inserted into the accommodating groove 361 also rotates correspondingly, so that the connector 440 rotates clockwise.

• • (b) in FIG. 9 shows a state of the clothes hanger 900 based on a change in the inclination of the accommodating groove 361.

When an extension direction of both sides of the accommodating groove 361 is defined parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240, the inserted protrusion 443 is also disposed parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240.

Therefore, the connector 440 is also disposed parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240, and the clothes hanger 900 is also disposed parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240.

However, when the accommodating groove 361 rotates and the extension direction of both sides thereof is defined at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240, the inserted protrusion 443 is also disposed at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240.

As a result, the connector 440 is also disposed at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240, and the clothes hanger 900 is also disposed at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240.

In this regard, the extension direction of both sides of the accommodating groove 361 varies in a reciprocally rotating manner counterclockwise and clockwise based on the rotation of the rotatable body 350 as shown in (a) in FIG. 9, so that the power transmitter 400, the hanger part 700, and the clothes hanger 900 may also reciprocally rotate counterclockwise and clockwise.

FIG. 10 shows a rotation state of the power transmitter 400.

The power transmitter 400 reciprocally rotates clockwise and counterclockwise by the accommodating groove 361 and the inserted protrusion 443 disposed on the gripping portion 442 without varying the location thereof around the penetrating body 441.

Therefore, the hanger part 700 and the clothes hanger 900 also reciprocally rotate only in the left and right direction without varying the locations thereof around the penetrating body 441. Therefore, vibration may be minimized when the moving hanger 100 is operating. Further, even when an rpm of the driver 200 is further increased, the vibration and noise generated from the moving hanger 100 may not significantly increase.

FIG. 11 shows another embodiment of the moving hanger 100.

The moving hanger 100 may have the same structure as in the above-described embodiment except for the connector 440 and the displacement generator 300.

The displacement generator 300 may include the rotatable body 350 coupled to the rotation shaft 240, and may include the contact portion 360 disposed on the outer circumferential surface of the rotatable body 350 and capable of being in contact with the connector 440.

The contact portion 360 may protrude outwardly from the rotatable body 350, and the gripping portion 442 of the connector 440 may accommodate at least a portion of the contact portion 360 therein and rotatably support the same.

The contact portion 360 may protrude along the circumference of the rotatable body 350, and may be disposed at an angle with respect to the diameter direction of the rotatable body 350 or the diameter direction of the rotation shaft 240.

FIG. 12 shows a detailed structure of the moving hanger 100 in FIG. 11.

The rotatable body 350 may be formed in a cylindrical or disc shape that is coupled to the rotation shaft 240 and rotates. The contact portion 360 may include the protruding ring 362 that is formed in a ring shape that protrudes outward from the outer circumferential surface of the rotatable body 350.

The protruding ring 362 may be formed as a width of the rotatable body 350 becomes smaller as it goes from the shaft coupling portion 351 toward the outer circumferential surface.

In addition, the protruding ring 362 may be formed to protrude from the outer circumferential surface of the rotatable body 350.

In any case, the protruding ring 362 may have a width or a breadth smaller at the rotatable body 350 than at the shaft coupling portion 351.

In one example, the protruding ring 362 may be formed with a uniform width along the circumference of the rotatable body 350.

The connector 440 may be rotatably supported on the support bearing 460 by penetrating through the support hole 820 of the support 800. The connector 440 may be provided to be in contact with both sides of the protruding ring 362, and may rotatably support both sides of the protruding ring 362.

The connector 440 may support the protruding ring 362 to slide and may rotate in the left and right direction depending on a location of the protruding ring 362.

The connector 440 may rotate an entirety of the auxiliary supports 420, the hangers 700, and the clothes hangers 900 while supporting the auxiliary supports 420, the hangers 700, and the clothes hangers 900.

FIG. 13 shows a detailed structure of the moving hanger.

To avoid redundant description, a description will focus on parts different from those in the above-described embodiment.

The contact portion 360 includes the protruding ring 362 that protrudes at an angle with respect to the rotation shaft along the circumference of the rotatable body 350.

The rotatable body 350 may have a diameter much greater than a thickness.

A thickness of the shaft coupling portion 351 of the rotatable body 350 may be much greater than a thickness of the protruding ring 362.

The protruding ring 362 may have a constant thickness along the outer circumferential surface of the rotatable body 350, and may be disposed at an angle with respect to the diameter direction of the rotatable body 350.

The connector 440 may include a seating body 445 that accommodates at least a portion of an outer circumferential surface of the protruding ring 362 therein.

The seating body 445 may accommodate an entire surface of the protruding ring 362 therein so as to rotate the connector 440 along a change in an inclination of the protruding ring 362.

That is, the seating body 445 may grip an entirety of both surfaces of the protruding ring 362 based on the length direction of the rotation shaft 240.

The seating body 445 may be formed at a free end of the gripping portion 442.

The seating body 445 may also be formed integrally with the gripping portion 442

However, to enhance formability of the seating body 445, the seating body 445 may be fixed by being coupled to one end of the gripping portion 442.

The gripping portion 442 may include the first gripping portion 4421 extending from the penetrating body 441 to one side of the protruding ring 362, and the second gripping portion 4422 extending from the penetrating body 441 to the other side of the protruding ring 362.

The seating body 445 may be formed in a plurality of pieces so as to be coupled to the first gripping portion 4421 to accommodate the protruding ring and coupled to the second gripping portion 4422 to accommodate the protruding ring.

A free end of the first gripping portion 4421 and a free end of the second gripping portion 4422 may be disposed at the same vertical level.

The connector 440 may further include a support groove 444 defined at a distal end or a free end of the gripping portion 442 and to which the seating body 445 may be fixed.

The support groove 444 may be defined as the distal end of the gripping portion 442 is recessed such that a portion of an outer peripheral surface of the seating body 445, su be inserted and seated.

The seating body 445 may protrude from the support groove 444 inward of the gripping portion 442 such that one surface thereof comes into contact with the protruding ring 362.

Therefore, the support groove 444 may be defined as a surface facing inward of the gripping portion 442 is open.

The first gripping portion may include a first support groove 4441 in which the seating body is seated at a distal end thereof, and the second gripping portion may include a second support groove 4442 in which the seating body is seated at a distal end thereof.

FIG. 14 shows detailed structures of the protruding ring and the seating body.

• • (a) and (b) in FIG. 14 show a structure of the protruding ring, and (c) in FIG. 14 shows a structure of the seating body.

The protruding ring 362 may be formed as the thickness of the rotatable body 350 becomes smaller as it approaches the outer circumferential surface.

The rotatable body 350 may include the shaft coupling portion 351 that is coupled to the rotation shaft 240 and supports the rotation shaft 240, a first inclined surface 352 that extends from one surface of the shaft coupling portion 351 to the protruding ring 362, and a second inclined surface 353 that extends from the other surface of the shaft coupling portion to the protruding ring.

Because the protruding ring 362 is disposed at an angle with respect to the outer circumferential surface of the rotatable body 350 or the diameter direction of the rotation shaft 240, the first inclined surface 352 and the second inclined surface 353 may have a width from the shaft coupling portion 351 to the protruding ring 362 varying along the circumference of the rotatable body 350.

In other words, the width of the first inclined surface 352 and the width of the second inclined surface 353 varies along the circumference of the rotatable body 350.

In addition, a width of a portion of the first inclined surface 352 disposed on one side based on the shaft coupling portion 351 in the rotatable body 350 and a width of a portion of the first inclined surface 352 disposed on the other side are different from each other, and a width of a portion of the second inclined surface 353 disposed on one side and a width of a portion of the second inclined surface 353 disposed on the other side are different from each other.

The first inclined surface 352 and the second inclined surface 353 may be point-symmetrical to each other with respect to a center of the shaft coupling portion 351.

The seating body 445 may include a fixed body 4451 that is seated in and fixed to the gripping portion, and a seating support part 4452 that protrudes from the fixed body 4451 to be in contact with the outer circumferential surface of the protruding ring 362.

The seating support part 4452 may be formed to be curved such that an exposed surface thereof supports each of both sides of the outer circumferential surface of the protruding ring 362.

The seating support part 4452 may have a thickness greater than a thickness of the fixed body 4451.

The seating body 445 may include a fixing hole 4453 that extends through the fixed body 4451. The fixing hole 4453 may be constructed such that a fastening member that extends through and is coupled to the support groove 444 passes therethrough.

FIG. 15 shows operating states of the power transmitter and the displacement generator in a top view of the moving hanger.

• • (a) in FIG. 15 shows arrangement of the power transmitter 400 and the protruding ring 362 based on the rotatable body.

The protruding ring 362 may be disposed at an angle on the outer circumferential surface of the rotatable body 350 and may be disposed along the circumference of the rotatable body 350. Accordingly, a rotation center of the protruding ring 362 may be disposed to be misaligned from the rotation shaft 240.

As a result, when the rotatable body 350 rotates, a location of the protruding ring 362 may vary.

Specifically, when the rotatable body 350 rotates, locations of both ends of the protruding ring 362 may vary from predetermined locations.

The protruding ring 362 is formed along the circumference at an angle with respect to the rotatable body 350, but there is a point where the rotation diameter of the rotatable body 350 and a rotation diameter of the protruding ring 362 meet each other.

Therefore, when the protruding ring 362 is located at the point where the rotation diameter thereof meets the rotation diameter of the rotatable body 350, the accommodating groove 361 may be defined parallel to the diameter direction of the rotation shaft as shown in the first drawing.

Therefore, the seating body 445 that accommodates therein and supports at least a portion of the protruding ring 362 may also be disposed parallel to the diameter direction of the rotation shaft 240, and the connector 440 may be disposed at a location corresponding to the diameter direction of the rotation shaft.

When the rotatable body 350 rotates 90 degrees, the protruding ring 362 also rotates, and the protruding ring 362 is disposed at an angle to the outer circumferential surface of the rotatable body 350. For example, as shown in the drawing, a front side of the protruding ring 362 moves to a right side and a rear side thereof moves to a left side.

As a result, the seating body 445 supporting the protruding ring 362 also rotates correspondingly, so that the connector 440 may rotate counterclockwise.

When the rotatable body 350 rotates 180 degrees, the protruding ring 362 further rotates, so that both side surfaces of the protruding ring 362 are disposed parallel to the outer circumferential surface of the rotatable body 350. As a result, the seating body 445 supporting the protruding ring 362 also rotates correspondingly, so that the connector 440 may slightly rotate clockwise and be disposed parallel to the diameter direction of the rotation shaft 240.

When the rotatable body 350 rotates 270 degrees, the protruding ring 362 rotates further, so that the protruding ring 362 is disposed at an angle to the outer circumferential surface of the rotatable body 350. For example, as shown in the drawing, the front side of the protruding ring 362 moves to the left side and the rear side thereof moves to the right side.

As a result, the seating body 445 supporting the protruding ring 362 also rotates correspondingly, so that the connector 440 rotates clockwise.

• • (b) in FIG. 15 shows a state of the clothes hanger 900 based on a change in an inclination of the accommodating groove 361.

When an extension direction of both sides of the protruding ring 362 are defined parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240, the seating body 445 is also disposed parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240.

Therefore, the connector 440 is also disposed parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240, and the clothes hanger 900 is also disposed parallel to the diameter direction of the rotatable body 350 or the rotation shaft 240.

However, when the protruding ring 362 rotates and the extension direction of both sides thereof is defined at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240, the seating body 445 is also disposed at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240.

Accordingly, the connector 440 is also disposed at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240, and the clothes hanger 900 is also disposed at an angle to the diameter direction of the rotatable body 350 or the rotation shaft 240.

In this regard, the extension direction of both sides of the protruding ring 362 varies in a reciprocally rotating manner counterclockwise and clockwise based on the rotation of the rotatable body 350 as shown in (a) in FIG. 15, so that the power transmitter 400, the hanger part 700, and the clothes hanger 900 may also reciprocally rotate counterclockwise and clockwise.

FIG. 16 shows a rotation state of the power transmitter 400.

The power transmitter 400 does not vary the location thereof centered on the penetrating body 441, and reciprocally rotates clockwise and counterclockwise by the protruding ring 362 and the seating body 445 disposed on the gripping portion 442.

Therefore, the hanger part 700 and the clothes hanger 900 also reciprocally rotate only in the left and right direction without varying the locations thereof around the penetrating body 441. Therefore, the vibration may be minimized when the moving hanger 100 is operating. Further, even when an rpm of the driver 200 is further increased, the vibration and noise generated from the moving hanger 100 may not significantly increase.

The present disclosure may be modified and implemented in various forms, so that the scope of rights thereof is not limited to the above-described embodiments. Therefore, when the modified embodiment includes elements of the claims of the present disclosure, it should be considered to fall within the scope of the present disclosure.
