Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2009-0063414, filed on Jul. 13, 2009, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.

BACKGROUND

1. Field

The following description relates to a hermetic type compressor, and in particular, to a hermetic type compressor in which an electric component bracket installed on an outer surface of a hermetic container to be connected to an electric component cover may be easily changed in design and replaced with a new electric component bracket.

2. Description of the Related Art

In general, a hermetic type compressor employed by a cooling apparatus of an air conditioner or a refrigerator to compress a refrigerant includes a compression unit and a drive unit provided in a hermetic container. The compression unit performs compression of the refrigerant, and the drive unit provides driving force to compress the refrigerant.

The drive unit generally may include a motor, and connection terminals may be installed on the hermetic container so as to apply power to the drive unit.

One end of each connection terminal may be exposed to the outside of the hermetic container, and the other end of each connection terminal may be connected to the driving unit within the hermetic container. Electric components relating to drive of the drive unit, such as an overload protector and a relay, may be connected to the ends of the connection terminals exposed to the outside of the hermetic container.

Such electric components may be protected by an electric component cover, and an electric component bracket to be connected to the electric component cover may be provided on the outer surface of the hermetic container around the connection terminals.

In a conventional hermetic type container, the electric component bracket is made of a thin metal sheet and is fixed to the outer surface of the hermetic container by welding. A hole to expose the connection terminals is formed through the center of the electric component bracket, and fastening structures to be fastened to the electric component cover are provided at the edge of the electric component bracket.

Therefore, the electric components are connected to the connection terminals under the condition that the electric component bracket is welded onto the outer surface of the hermetic container. Under this state, the electric component cover is connected to the electric component bracket so as to cover the electric components.

However, in the conventional hermetic type container, in which the electric component bracket is fixed to the outer surface of the hermetic container by welding, the electric component bracket may be difficult to replace, thereby causing an inconvenience.

In the conventional hermetic type container, if the electric component bracket is partially damaged or is defective, replacement of only the electric component bracket is difficult, and thus it may be necessary to replace the overall hermetic container including the electric component bracket with a new one.

Further, the number of the electric components may be changed or the electric components may be changed into other kinds according to the specifications of the hermetic type compressor. When the number or kinds of the electric components are changed, a type of the electric component cover to cover the changed electric components needs to be changed and the electric component bracket also needs to be replaced with a new type corresponding to the changed type of the electric component cover. Further, the type of the electric component cover may be changed according to an internal structure of a cooling apparatus in which the hermetic type compressor is installed even if the same electric components are covered with the electric component cover, and in this case, the electric component bracket needs to be replaced with a new type corresponding to the changed type of the electric component cover. That is, various types of electric component brackets are required according to user environments.

However, since the replacement of the electric component bracket fixed to the hermetic container with a different type of electric component bracket is difficult, if a new electric component bracket having a different specification is required in a conventional hermetic type compressor manufacturing line, manufacturing equipment to install the new electric component bracket on the outer surface of the hermetic container is prepared.

DETAILED DESCRIPTION

The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, apparatuses, and/or systems described herein. Accordingly, various changes, modifications, and equivalents of the systems, apparatuses, and/or methods described herein will be suggested to those of ordinary skill in the art. The progression of processing steps and/or operations described is an example; however, the sequence of steps and/or operations is not limited to that set forth herein and may be changed as is known in the art, with the exception of steps and/or operations necessarily occurring in a certain order. Also, descriptions of well-known functions and constructions may be omitted for increased clarity and conciseness.

A hermetic type compressor may be employed by a cooling apparatus of a refrigerator or an air conditioner to compress a refrigerant, and include a hermetic container forming an external appearance of the hermetic type compressor.

As shown in the example of FIG. 1, a compression unit 100 to perform compression of the refrigerant and a drive unit 200 to provide driving force to compress the refrigerant may be installed in the hermetic container 1. The drive unit 200 includes a motor including a stator 210 and a rotor 220, and a rotary shaft 230 to transmit the driving force of the drive unit 200 to the compression unit 100 is pressed into the rotor 200.

The compression unit 100 includes a piston 120 connected to an eccentric part 231 formed at one end of the rotary shaft 230 through a connecting rod 110 and rectilinearly reciprocating within a compression chamber.

When the rotor 220 is rotated through electrical interaction between the stator 210 and the rotor 220 by applying power to the stator 210 through the above structure, the rotary shaft 230 pressed into the rotor 220 is rotated together with the rotation of the rotor 220, and the piston 120 connected to the eccentric part 231 of the rotary shaft 230 through the connecting rod 110 rectilinearly reciprocates within the compression chamber, achieving compression of the refrigerant.

The hermetic type compressor may generally refer to a reciprocating compressor including a compression unit having a connecting rod and a piston. Hermetic type compressors may generally include a rotary compressor, each of which includes a drive unit driven by power, regardless of types of compression units, and a compression unit to perform compression of a refrigerant through driving of the drive unit.

As shown in the examples of FIGS. 1 and 2, a hermetic container 1 is formed by connecting an upper container 11 and a lower container 10 to each other. Connection terminals 31 for connection with electric components 20 relating to driving of the drive unit 200, i.e., applying of power to the drive unit 200, are installed at one side of the lower container 10. The connection terminals 31 are installed on the lower container 10 through a terminal housing 30. The terminal housing 30 passes through one side of the lower container 10, and the connection terminals 31 pass through the terminal housing 30 such that one end of each connection terminal 31 is exposed to the outside of the hermetic container 1 and the other end of each connection terminal 31 is connected to the drive unit 200 in the hermetic container 1. Electric components 20 relating to driving of the drive unit 200, including an overload protector 21 and a relay 22 are connected to the ends of the connection terminals 31 exposed to the outside of the hermetic container 1. Various kinds of the overload protector 21 and the relay 22 may be used, and the electric components 20 may include other electronic parts relating to driving of the drive unit 200 in addition to the overload protector 21 and the relay 22. The overload protector 21 and the relay 22 are illustrated simply to show examples of electric components relating to the driving of the drive unit 200.

The electric components 20 located at the outside of the hermetic container 1 are covered with an electric component cover 40. An electric component bracket 50 to be connected to the electric component cover 40 is provided on the outer surface of the hermetic container 1 around the connection terminals 31.

The hermetic type compressor is configured such that the electric component bracket 50 may be replaced with a new one according to user environments.

That is, with reference to FIGS. 2 to 7, for example, in a hermetic type compressor, bracket fixing members 60 are provided on the outer surface of the lower container 10 around the connection terminals 31 such that the electric component bracket 50 is detachably connected to the bracket fixing members 60. First fastening units 61 are provided on the bracket fixing members 60, and second fastening units 51, which may be detachably connected to the first fastening units 61, are provided on the electric component bracket 50.

Therefore, in the hermetic type compressor, if replacement of the electric component bracket 50 is required according to user environments, such as if the type of the electric component cover 40 is changed as the number or the kinds of the electric components 20 are changed, the design of the electric component cover 40 is changed, or the electric component bracket 50 is damaged, the electric component bracket 50 may be simply replaced with a new one.

The bracket fixing members 60 may be formed in the shape of a small metal piece, and regions of the bracket fixing members 60 may respectively form the first fastening units 61. The first fastening unit 61 of each bracket fixing member 60 includes a protrusion part 61a protruded outwardly from the outer surface of the hermetic container 1 when each bracket fixing member 60 is installed on the outer surface of the hermetic container, and a hanging part 61b having a cross-sectional area greater than that of the protrusion part 61a and provided at one end of the protrusion part 61a. The other end of the protrusion part 61a opposite to the hanging part 61b forms a fixing surface 62 welded to the outer surface of the lower container 10 to fix each bracket fixing member 60.

The electric component bracket 50 may be formed in the shape of a thin metal sheet. An exposure hole 52 to expose the connection terminals 31 and the terminal housing 30 is formed through the center of the electric component bracket 50. In this example, each second fastening unit 51 is provided in the shape of a hole formed through the electric component bracket 50 around the exposure hole 52.

Each second fastening unit 51 includes a hanging part pass hole 51a configured to pass the hanging part 61b of the first fastening unit 61, and a protrusion part fitting hole 51b formed at the top of the hanging part pass hole 51a and having a width corresponding to the width of the protrusion part 61a such that the protrusion part 61a of the first fastening unit 61 may be fitted into the protrusion part fitting hole 51b. The hanging part pass hole 51a and the protrusion part fitting hole 51b are formed so as to be communicated with each other. A length of the protrusion part fitting hole 51b in the vertical direction may be equal to or be greater than by a designated length a thickness of the protrusion part 61a in the vertical direction.

Therefore, when the electric component bracket 50 is fastened to the bracket fixing members 60 under the condition that the bracket fixing members 60 are welded onto the hermetic container 1, the electric component bracket 50 may move toward the hermetic container 1 under the condition that the electric component bracket 50 is located in front of the bracket fixing members 60 so as to cause the hanging parts 61b of the first fastening units 61 and the hanging part pass holes 51a of the second fastening units 51 to coincide with each other, as shown in FIGS. 4 and 5, allowing the hanging parts 61b of the first fastening units 61 to pass through the hanging part pass holes 51a of the second fastening units 51. Thereafter, the electric component bracket 50 is pulled downwards so as to fit the protrusion parts 61a of the first fastening units 61 into the protrusion part fitting holes 51b of the second fastening units 51, as shown in FIGS. 6 and 7, for example. The electric component bracket 50 may be simply fastened to the bracket fixing members 60 by hanging the hanging parts 61b of the first fastening units 61 onto the protrusion part fitting holes 51b of the second fastening units 51.

When the electric component bracket 50 is pulled forwardly from the hermetic container 1, under the condition that the electric component bracket 50 is lifted up such that the hanging parts 61b of the first fastening units 61 and the hanging part pass holes 51a of the second fastening units 51 coincide with each other, so as to allow the hanging parts 61b to come out of the hanging part pass holes 51a, the electric component bracket 50 is separated again from the bracket fixing members 60. Therefore, the electric component bracket 50 may maintain a state of being firmly fixed to the bracket fixing members 60 unless the hanging parts 61b of the first fastening units 61 come out of the hanging part pass holes 51a of the second fastening units 51 by lifting up the electric component bracket 50 fastened to the bracket fixing members 60.

To stably maintain the fastened state of the electric component bracket 50 onto the outer surface of the hermetic container 1, at least two bracket fixing members 60 may be provided around the connection terminals 31. In one example, three bracket fixing members 60 are disposed in a triangular shape around the terminal housing 30, supporting the electric component bracket 50 at three points. However, any suitable number of bracket fixing members 60 may be used.

Further, to prevent or limit movement of the electric component bracket 50 fastened to the bracket fixing members 60, a protruding length of the protrusion parts 61a of the first fastening units 61 may be about equal to a thickness of the electric component bracket 50.

FIG. 8 illustrates an example in which the electric component cover 40 is separated from the electric component bracket 50 fixed to the outer surface of the hermetic container 1 through the bracket fixing members 60.

The electric component cover 40 may be provided in the shape of a box having one surface opened toward the hermetic container 1. The electric component cover 40 may be an injection-molded product made of plastic so as to be elastically deformable, and have a small wall thickness.

The electric component cover 40 may be detachably connected to the electric component bracket 50. For this purpose, third fastening units 53 are provided on the electric component bracket 50, and fourth fastening units 41 to which the third fastening units 53 may be detachably connected are provided on the electric component cover 40.

The third fastening units 53 are formed at the edge of the electric component bracket 50 so as not to interfere with the first fastening units 61 of the bracket fixing members 60. Each third fastening unit 53 includes a protrusion piece 53a protruded toward the electric component cover 40, and a hanging hole 53b formed through the protrusion piece 53a.

Further, each fourth fastening unit 41 includes a support piece 41a provided at the inside of the side wall of the electric component cover 40 and separated from the side wall of the electric component cover 40 so as to be supported by the inner surface of the protrusion piece 53a, and a hanging protrusion 41b protruded from the outer surface of the support piece 41a so as to be fitted into the hanging hole 53b. The support piece 41a may have a small thickness so as to be elastically deformed to fit into the hanging hole 53b.

Therefore, the electric component bracket 50 and the electric component cover 40 may be detachably fastened to each other under the condition that the electric component bracket 50 is fixed to the outer surface of the lower container 10 through the bracket fixing members 60. For example, the electric component cover 40 may be pressed toward the hermetic container 1 while contacting the front surface of the electric component bracket 50 so as to fit the hanging protrusions 41b of the fourth fastening units 41 into the hanging holes 53b of the third fastening units 53.

To separate the electric component cover 40 from the electric component bracket 50, external force may be applied to both side walls of the electric component cover 40 so as to cause both side walls to get closer to each other. Then, the support pieces 41a of the fourth fastening units 41 may be elastically deformed and thus the hanging protrusions 41b may become separated from the hanging holes 53b of the third fastening units 53. By pulling the electric component cover 40 forwardly from the hermetic container 1, the electric component cover 40 is separated from the electric component bracket 50.

As described above, in the hermetic type compressor, the electric component bracket 50 may be detachably connected to the outer surface of the hermetic container 1 through the first fastening units 61 of the bracket fixing members 60 connected to the outer surface of the hermetic container 1 and the second fastening units 51 provided on the electric component bracket 50. Thus, if the electric component bracket 50 is defective or damaged, there may be no need to replace the whole of the lower container 10, as only the electric component bracket 50 may be replaced.

Further, in the hermetic type compressor, as far as the first fastening units 61 and the second fastening units 51 may be detachably connected to each other, the electric component bracket 50 may be replaced with any one of various types of electric component brackets in which other structures except for the second fastening units 51 are different. Therefore, if a change in design of the electric component bracket 50 is required, for example, in accordance with a change in design of the electric component cover 40, or a change in specification of the electric component bracket 50, the electric component bracket 50 may be simply replaced with various types of electric component brackets.

Further, in the hermetic type compressor, the electric component bracket 50 may be fastened to the outer surface of the hermetic container 1 in a simple fit manner. Thus, although a hermetic type compressor manufacturer may manufacture a hermetic type compressor provided with only the bracket fixing members 60, without the electric component bracket 50, and may provide the hermetic type compressor to a user, the user may easily prepare the electric component bracket 50 detachably connected to the bracket fixing members 50 of the supplied hermetic type compressor. Otherwise, although a manufacturer simultaneously provides various kinds of electric component brackets having different types to a user, the user may select an electric component bracket desired by the user out of the various electric component brackets as long as the electric component brackets have the same structure of second fastening units.

The bracket fixing members and the second fastening units provided to detachably connect the electric component bracket to the bracket fixing members may be modified into various types differing from the type.

That is, as shown in FIGS. 9 to 11, which illustrate other examples, a pair of bracket fixing members 60′ is disposed around connection terminals 31 such that the bracket fixing members 60′ are separated from each other by a designated interval in the circumferential direction. However, at least three bracket fixing members 60′ may be provided as far as the bracket fixing members 60′ are disposed around the connection terminals 31 such that the bracket fixing members 60′ are separated from each other by a designated interval in the circumferential direction.

A pair of second fastening units 51′ is also provided on an electric component bracket 50′ so as to correspond to the number of the bracket fixing members 60′. When the electric component bracket 50′ is rotated under the condition that the second fastening units 51′ enter an area between the bracket fixing members 60′, the second fastening units 51′ are fastened with first fastening units 61′ provided on the bracket fixing members 60′.

The second fastening units 51′ are provided on the rear surface of the electric component bracket 50′ around an exposure hole 52 such that the second fastening units 51′ are separated from each other by a designated interval in the circumferential direction. In this example, each second fastening unit 51′ includes an extension part 51a′ extended backwardly from the rear surface of the electric component bracket 50′, and a fitting part 51b′ bent from the extension part 51a′ in the radial direction so as to be parallel with the electric component bracket 50′.

Further, each first fastening unit 61′ includes a fitting groove into which the fitting part 51′ of the second fastening unit 51′ may be fitted while sliding in the circumferential direction when the electric component bracket 50′ is rotated. That is, the bracket fixing member 60′ is formed to have an arc-shaped cross section, i.e., about an L-shaped cross section and is welded to the outer surface of the hermetic container 10, and the first fastening unit 61′ is an arc-shaped fitting groove formed between the bracket fixing member 60′ and the outer surface of the hermetic container 10.

Therefore, in this example, to connect the electric component bracket 50′ to the hermetic container 10, the fitting parts 51b′ of the second fastening units 51′ enter the area between the bracket fixing members 60′ under the condition that the electric component bracket 50′ is rotated by an angle of 90 degrees, as shown in FIG. 10, for example. Thereafter, when the electric component bracket 50′ is rotated by an angle of 90 degrees in the clockwise direction so as to stand erect, as shown in FIG. 11, the fitting parts 51b′ of the second fastening units 51′ are fitted into the first fastening units 61′ and then the electric component bracket 50′ may be simply connected to the outer surface of the hermetic container 10.

To prevent or limit movement of the electric component bracket 50′ under the condition that the first fastening units 61′ and the second fastening units 51′ are fastened to each other, the fitting parts 51b′ and the first fastening units 61′ may be connected to each other in an interference fit manner. Further, to complete fastening of the first fastening units 61′ and the second fastening units 51′ to each other under the erect standing state of the electric component bracket 50′, a restriction protrusion 63 to restrict sliding of the fitting part 51b′ is provided at one end of each first fastening unit 61′.

In order to separate the electric component bracket 50′ fixed to the outer surface of the hermetic container 10 from the hermetic container 10, the electric component bracket 50′ is rotated from the state of FIG. 11 in the counterclockwise direction so as to be converted into the state of FIG. 10. The fitting parts 51b′ may come out of the first fastening units 61′, and then the electric component bracket 50′ may simply be separated from the hermetic container 10.

Other parts in this example, except for the first and second fastening units 61′ and 51, may be the same as those in the examples of FIGS. 1 to 8, and an attachment and detachment structure between the electric component bracket 50′ and the electric component cover 40 in this example is substantially similar to that described above.

As is apparent from the above description, a hermetic type compressor may enable an electric component bracket for connection with an electric component cover to be detachably connected to the outer surface of a hermetic container through bracket fixing members.

Therefore, if replacement of the electric component bracket is required according to user environments, such as if the type of the electric component cover is changed as the number or the kinds of electric components are changed, if the design of the electric component cover is changed, or if the electric component bracket is damaged, the electric component bracket may be simply replaced with a new one, and design change of the electric component bracket may be more easily performed.

A number of examples have been described above. Nevertheless, it will be understood that various modifications may be made. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
