Abstract: Provided is a drum washing machine. The drum washing machine, which is provided with a rotating body on the rear a drum, is able to smoothly switch between a first form in which the drum and the rotating body rotate independently and a second form in which the drum and the rotating body rotate integrally. When switching from a biaxial driving form to a uniaxial driving form and vice versa, a control part rotates a rotor clockwise and anticlockwise in a manner of taking a reverse action 1 and a reverse action 2 during the operation of a torque motor, i.e., during an action of moving a clutch body by virtue of a moving mechanism. The reverse action 1 includes an action of stopping the rotor rotating clockwise direction, and the reverse action 2 includes an action of stopping the rotor rotating anticlockwise.

Abstract: The present disclosure reduces sound generated when a driving mode of a drum washing machine having a rotating body on a rear part of a drum is switched between a first mode and a second mode. The first mode is a driving mode in which the drum and the rotating body independently rotate, and the second mode is a driving mode in which the drum and the rotating body integrally rotate. A bearing-side cushioning member is arranged on a clutch carrying plate side. The bearing-side cushioning member firstly touches an object side when a spline of a clutch body is engaged with a spline of the clutch carrying plate, so as to reduce an impact force generated between the clutch body and the clutch carrying plate.

In a washing process of the first washing mode, the control part enables the driving part to operate in the uniaxial driving form and also enables the heater to operate. Further, in a washing process of the second washing mode, the control part enables the driving part to operate in the biaxial driving form and also enables the heater to operate in such a manner that heat applied to the water is reduced compared with the first washing mode.

Abstract: A drum washing machine is provided. The drum washing machine includes: an outer tank arranged in a housing; a drum, which is arranged in the outer tank and capable of rotating about a horizontal shaft H; a rotating body, which is arranged at a rear part of the drum, a surface of the rotating body being provided with a projection; and a driving part, configured to drive the drum and the rotating body to coaxially rotate at different rotating speeds. The drum has a baffle arranged on an inner circumferential surface of the drum, which is used as a moving unit configured to move the washings in the drum towards the rotating body. The baffle has gathering surfaces for gathering the washings through a rotation of the drum. The gathering surfaces are inclined so that the side of the rotating body is lagged in a rotation direction of the drum.

Abstract: The present invention provides a washing machine configured such that a gas having a cleaning function is prevented from leaking to the outside. The washing machine performs an ozone cleaning step for cleaning dry laundry by supplying ozone to the laundry prior to a washing step. Before the start of the ozone cleaning step, a dehumidification water valve (14) is opened to once retain dehumidification water in a bottom of an outer tub (7). Then, water is retained in an overflow trap (45) by utilizing the dehumidification water, whereby a flow passage extending from the outer tub (7) to the outside is sealed with the water. Further, a detergent valve (55) or a finishing agent valve (56) is opened to retain water in a water supply trap (24), whereby a flow passage extending from the outer tub (7) to the outside is sealed with the water.

Abstract: An engaging groove part 25 is provided at the outer circumferential edge of a rotor 20b of an outer-rotor type motor directly connected to the main shaft 14 of a drum 13, and on the other hand, a drum locking device 21 is provided directly below the shaft. The drum locking device 21 is constructed so that a lock pin moves up and down in response to rotation of a torque motor, and when the lock pin advances and fits into the groove of the engaging groove pan 25, the position of the drum 13 is fixed. Thereby, the stopping position of the drum can be fixed with a simple construction.

Abstract: In a drum type washing machine, a drum 23 is mounted to rotate about a horizontal axis extending in the lateral direction in a tub 20. A tub opening 20b with a tub door 20a is formed in the tub 20 under the throw-in opening 3 formed in the front part of the top of the housing. A drum opening 23a with a drum door composed of a double door opening frontward and backward is formed in the peripheral wall of the drum 23. The drum 23 is stopped so that the drum opening 23b coincides with the tub opening 20b. The drum door 23a, forced into its opening direction, is held in a closed position by an engagement of a claw 43 and an engagement hole 53. When a user rotates a operation lever 63b for latching or unlatching the tub door 20, the drum door open/close mechanism 65 functions to make two rods 65a and 65b project or withdraw, whereby the drum door 23a is brought into an engaged or unengaged state. By this mechanism, the drum door 23a opens or closes with the opening or closing operation of the tub door 20a.

Abstract: In a drum type washing machine according to the present invention, an electrolytic device 60 for electrolyzing water stored in an outer tub 2 is attached to an outer peripheral surface wall 21 of the outer tub 2. The water stored in the outer tub 2 flows into an electrolytic tub 62 through an inlet tube 64A and a connection tube 63A, and is electrolyzed by a plurality of electrode plates 61, after which it is returned to the outer tub 2 through a connection tube 63B and an outlet tube 64B. The electrolyzed water contains active oxygen (O2−), hypochlorous acid (HClO), etc. having a sterilizing effect. Accordingly, the detergency is improved.
