Description

{CLOTHES TREATING APPARATUS}

The present invention relates to a clothes processing apparatus capable of improving durability of a refrigerant pipe by blocking vibration of a compressor from being transmitted to a heat exchanger in a clothes dryer to which a heat pump system is applied.

Generally, a clothes processing apparatus is a device capable of performing a function of drying clothes washed or laundered, or performing both functions.

In recent years, there has been developed a clothes processing apparatus provided with a steam generating device and having a refresh function or a sterilizing function such as removal of wrinkles, smell removal, and static electricity removal of clothes.

For example, a drum type drier for drying clothes after washing, a cabinet type drier for hanging and drying clothes, and a refresher for refreshing clothes by supplying hot air to clothes have been developed.

Among the clothes processing apparatuses, a refresher, a dryer, or the like is provided with a heat source supply unit to supply hot air to clothes as the air is heated. The heat source supply unit includes a gas type heater for heating the air by burning gas according to a heat source, an electric heater for heating the air by electric resistance, and a heat pump system for circulating the refrigerant through a compressor, a condenser, an expansion valve, And a heat pump system for heating the air. Recently, a heat pump system having an advantage of energy efficiency has been actively developed.

On the other hand, a clothes dryer to which the heat pump system is applied includes a drum, a driving motor, a compressor, an evaporator, a condenser, and the like in a cabinet. The drum provides a cylindrical receiving space for receiving and drying the clothes, and the space occupied by the drum in the entire space inside the cabinet is much larger than the other components. For example, the outer periphery (radius) of the drum descends from the top of the cabinet to the bottom as well as the left and right directions of the cabinet.

The compressor, the condenser, the expansion valve, and the evaporator constituting the heat pump cycle are arranged using the remaining space except for the space occupied by the drum, and the remaining space excluding the space occupied by the drum can be left and right side spaces of the cabinet.

For example, the evaporator and the condenser may be disposed in the front-rear direction in one side space of the cabinet, and the compressor of a relatively large volume and size may be disposed in the other side edge space of the cabinet.

However, when the compressor is located at the corner of the cabinet due to the space limitation inside the cabinet, the refrigerant pipes extending from the compressor to the evaporator and the condenser are asymmetric with each other, and the length of one of the pipes becomes long.

In addition, the vibrations generated in the compressor are transmitted along the refrigerant pipe, and the longer the length of the refrigerant pipe in which the vibration is generated, the larger the amplitude. Therefore, the refrigerant pipe having a relatively long length in the refrigerant pipe is fixed by welding with the evaporator or the condenser There is a problem that damage such as cracks occurs due to a larger impact at the portion.

Further, when the refrigerant leaks from the damaged refrigerant pipe, the performance of the heat pump system deteriorates as well as the drying performance.

D1: Public Utility Model Publication No. 1999-002665 (Jan. 25, 1999)

It is therefore an object of the present invention to provide a clothes processing apparatus capable of preventing a refrigerant pipe from being damaged due to an increase in the length of a refrigerant pipe extending from a compressor to an evaporator or a condenser and an impact caused by vibration.

According to another aspect of the present invention, there is provided a clothes processing apparatus comprising: a cabinet; A drum rotatably installed in the cabinet; And a heat exchanger disposed between the lower portion of the drum and the lower surface of the cabinet and spaced apart from each other in the opposite direction of the rotation axis of the drum, the heat exchanger being spaced apart from the drum in the forward and backward directions, A first refrigerant pipe for connecting the compressor and the evaporator, and a second refrigerant pipe for connecting the compressor and the condenser, wherein the first refrigerant pipe connects the compressor and the condenser, The second refrigerant piping further includes a holder which supports the relatively long refrigerant pipe among the first and second refrigerant pipes and blocks vibration generated in the compressor.

According to an embodiment of the present invention, the holder includes: a support having a receiving groove therein to enclose the refrigerant pipe; And a pressing portion for pressing the refrigerant pipe accommodated in the receiving groove.

This makes it easy to insert the refrigerant pipe into the inside of the holder when the holder is divided into two parts, that is, the supporting part and the pressing part. Further, it is possible to support the refrigerant pipe by the supporting portion, and pressurize the refrigerant pipe by the pressing portion.

According to an embodiment of the present invention, there is provided a heat exchanger comprising: a heat exchanger accommodating part for accommodating therein the evaporator and the condenser; And a heat exchanger cover which is fastened to the upper portion of the heat exchanger accommodating portion, wherein the supporter is integrally provided on one side of the heat exchanger accommodating portion, the press portion is integrally provided on one side of the heat exchanger cover, The pressing of the pressing portion can be performed together with the fastening of the base cover.

Accordingly, since the holder is integrally formed with the heat exchanger accommodating portion and the cover without being formed as a separate component, the number of components is reduced and the installation space can be reduced.

According to an embodiment of the present invention, the support portion includes a contact portion having the same shape as a part of a cross section of the refrigerant pipe so as to be in contact with an outer surface of the refrigerant pipe; An inlet portion extending upwardly from the contact portion and forming an opening at an upper end thereof; And a seating portion extending laterally from the inlet portion, the pressing portion extending from the heat exchanger cover, the upper cover being seated in a part of the seating portion and covering the opening of the supporting portion; And a pressing projection extending downward from the upper cover and pressing the upper portion of the refrigerant pipe.

According to an embodiment of the present invention, the pressing portion may be integrally connected to the heat exchanger cover by a plurality of reinforcing ribs extending from the heat exchanger cover.

As a result, the holding force of the holder can be increased through the reinforcing rib.

According to an embodiment of the present invention, the support portion may include an elastic vibration absorbing plate on the inner surface.

Thus, vibrations transmitted from the refrigerant pipe can be absorbed, and noise can be reduced when there is a clearance between the refrigerant pipe and the receiving groove.

According to an embodiment of the present invention, the pressure projection may further include an elastic vibration-absorbing member attached to the end portion so as to be able to contact the refrigerant pipe.

Thereby, the vibration absorbing member is provided between the upper portion of the refrigerant pipe and the pressing projection, so that the pressing property and the adhesion property can be improved.

According to the present invention configured as described above, the vibration generated in the compressor is blocked by the holder installed in the middle of the pipe, so that the pipe connected to the heat exchanger can be prevented from being damaged have.

Thus, the durability of the refrigerant pipe can be improved. It is also possible to solve the problem of deterioration of the performance of the heat pump system and deterioration of the drying performance due to refrigerant leakage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A garment processing apparatus according to the present invention will be described below in detail with reference to the drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

INDUSTRIAL APPLICABILITY The present invention can be applied to a garment processing apparatus having a clothes dryer, a dryer and a steam supply device having a drying function and having a refresh function and a sterilizing function. It may also be applied to a drum type drier and a cabinet type drier.

1 is a schematic view schematically showing a configuration of a clothes processing apparatus 100 having a heat pump system 140 according to the present invention.

The clothes processing apparatus 100 shown in FIG. 1 exemplifies a drum type dryer and may include a cabinet, a clothes receiving unit, a driving unit, a blowing fan 130, and a heat pump system 140.

The cabinet forms the outline of the product.

A garment accommodating portion is provided inside the cabinet to accommodate the clothes. In the case of a drum type clothes dryer, a drum 110 is installed inside the cabinet to accommodate clothes. The drum 110 can rotate around a rotation axis disposed in the cabinet in a horizontal direction or in an inclined direction at an angle.

The drum 110 has a hollow cylindrical shape and provides a receiving space for loading and drying clothes, which are objects to be dried. An opening is formed in the front face of the drum 110, a slot is formed in the front face of the cabinet, and the opening and the slot are communicated with each other, so that the clothes can be inserted into the drum 110. The door may be hinged to the cabinet for opening and closing the inlet.

In order to efficiently dry clothes to be dried, the drum 110 is rotatably installed, and a lifter is provided inside the drum 110, so that the clothes can be tumbled by the lifter.

The driving unit provides a rotational force by using a motor or the like, and the output shaft of the motor and the drum 110 are connected to each other by a power transmitting means such as a belt, and the rotational force of the motor is transmitted to the drum 110, .

The air flow path may be connected to the drum 110 to form a closed loop for air circulation. For example, the air flow path may be provided with the air duct 120. A drum outlet for discharging air is formed in a lower portion of the front end of the drum 110 and a drum inlet for introducing air into the drum 110 is formed and the air duct 120 is communicated with the drum outlet and the inlet , The air circulation can be induced.

The blowing fan 130 includes an air duct 121 extending from the drum outlet to the evaporator 141 of the heat pump system 140 or an air duct 122 extending from the condenser 142 of the heat pump system 140 to the drum inlet As shown in Fig. The air blowing fan 130 may be driven by a separate fan motor to apply power to the air to pass through the inside of the drum 110 and circulate the air discharged from the drum 110 back to the drum 110.

A lint filter is installed at the drum outlet so that the lint contained in the air can be collected as the air discharged from the drum 110 passes through the lint filter.

The clothes (also referred to as "cloth") evaporate moisture by hot air supplied into the drum 110, and the air passing through the drum 110 is discharged from the drum 110 while containing moisture evaporated from clothes. The high temperature and high humidity air discharged from the drum 110 moves along the air flow path while being heated by the heat pump system 140 and then circulated to the drum 110.

The heat pump system 140 comprises an evaporator 141, a compressor 143, a condenser 142 and an expansion valve 144. The heat pump system 140 may use refrigerant as the working fluid. The refrigerant moves along the refrigerant pipe 145, and the refrigerant pipe 145 forms a closed loop for circulation of the refrigerant. The evaporator 141, the compressor 143, the condenser 142 and the expansion valve 144 are connected by the refrigerant pipe 145 so that the refrigerant is supplied to the evaporator 141, the compressor 143, the condenser 142, (144).

The evaporator 141 is installed in the air passage so as to communicate with the drum outlet, exchanges heat between the air discharged from the drum outlet and the refrigerant, and recovers the amount of heat of the air discharged from the drum 110 without discharging it to the outside of the dryer.

The condenser 142 is installed in the air passage so as to communicate with the drum inlet and exchanges heat between the refrigerant and the air passing through the evaporator 141 so that the amount of heat absorbed by the evaporator 141 is converted into air to be introduced into the drum 110 It radiates heat.

The evaporator 141 and the condenser 142 may be installed inside the air duct 120. The evaporator 141 may be connected to the drum outlet, and the condenser 142 may be connected to the drum inlet.

The evaporator 141 and the condenser 142 may be fin-and-tube type heat exchangers. The pin-and-tube type is a type in which a plate-shaped pin is attached to a hollow tube. As the refrigerant flows along the inside of the tube and the air passes over the tube outer surface, the refrigerant and the air exchange heat with each other. The fins are used to expand the heat exchange area between the air and the refrigerant.

The high temperature and high humidity air discharged from the drum 110 is higher in temperature than the refrigerant of the evaporator 141. As the heat of the air passes through the evaporator 141 and is taken to the refrigerant of the evaporator 141, . As a result, the hot and humid air is dehumidified (the moisture is removed) by the evaporator 141, and the condensed condensed water is collected through the condensed water collecting unit provided at the lower part of the evaporator 141 and then discharged to the outside.

The heat source of the heat absorbed in the evaporator 141 is moved to the condenser 142 through the refrigerant and is supplied to the evaporator 141 (low heat source) to move the heat source to the condenser 142 ) And the condenser 142. The compressor 143 is connected to the condenser 142,

The compressor 143 compresses the refrigerant vaporized in the evaporator 141 to produce a high temperature and high pressure refrigerant and moves the high temperature and high pressure refrigerant to the condenser 142 along the refrigerant pipe 145. The compressor 143 may be an inverter type compressor 143 capable of varying the frequency to control the discharge amount of the refrigerant.

The expansion valve 144 is installed in a refrigerant pipe 145 extending from the condenser 142 to the evaporator 141. The refrigerant condensed in the condenser 142 is expanded to a low temperature and low pressure refrigerant to be supplied to the evaporator 141 .

The refrigerant flows into the compressor 143 in a gaseous state and becomes high temperature and high pressure by the compression of the compressor 143. The refrigerant of high temperature and high pressure flows into the condenser 142 And is changed from the gas state to the liquid state as heat is discharged from the condenser 142 to the air.

Subsequently, the refrigerant in the liquid state flows into the expansion valve 144 and is changed to a low temperature and a low pressure by the throttling action of the expansion valve 144 (or a capillary or the like), and the low temperature and low pressure liquid refrigerant flows into the evaporator 141 And evaporates the refrigerant from the liquid state to the gaseous state as the evaporator 141 absorbs heat from the air.

Thus, the heat pump system 140 repeatedly circulates the refrigerant through the compressor 143, the condenser 142, the expansion valve 144, and the evaporator 141, and provides a heat source to the air circulated to the drum 110 .

2 is a perspective view showing an example of a heat pump clothes dryer according to the present invention.

In the case of the heat pump clothes dryer according to the present invention, the heat pump system 140 and the motor are located between the lower part of the drum (not shown) and the base bottom.

The base located at the bottom of the cabinet forms a space for mounting the heat pump system 140 and the like.

For example, the base 101 shown in Fig. 2 accommodates a heat exchanger accommodating portion 102 and a blowing fan 130 disposed on the right side, a compressor 143 disposed on the left side, and the like.

The heat exchanger accommodating portion 102 has an accommodating space for accommodating the evaporator 141 and the condenser 142 therein and is open upward. The evaporator 141 is disposed in front of the cabinet, that is, toward the drum outlet, and the condenser 142 is disposed behind the cabinet, i.e., toward the drum inlet.

The inlet side of the evaporator 141 is connected to the air duct 120 connected to the drum outlet and the outlet side of the condenser 142 is connected to the air duct 120 connected to the drum inlet. The blowing fan 130 is disposed behind the condenser 142 and may be installed in the air duct 120 extending from the condenser 142 to the drum inlet.

A heat exchanger cover 103 is provided at an upper portion of the heat exchanger accommodating portion 102 to cover the upper portion of the heat exchanger accommodating portion 102. The heat exchanger cover 103 and the heat exchanger accommodating portion 102 are respectively provided with a plurality of fastening portions along the edge portions and are fastened by fastening means such as bolts or the like.

The heat exchanger cover 103 is preferably made of a high strength material for covering the upper space of the evaporator 141 and the condenser 142 and for protecting the heat exchanger from external impact.

The compressor 143 is forced to be disposed in the corner space of the cabinet due to the limited internal space of the cabinet formed between the lower portion of the drum and the bottom surface of the base 101. The evaporator 141 and the condenser 142 are disposed in front of and behind the cabinet The refrigerant pipe of one of the refrigerant pipes 145 connecting the compressor 143 and the heat exchanger is long.

The first refrigerant pipe 145a connecting the inlet of the compressor 143 and the evaporator 141 of the refrigerant pipe 145 shown in Figure 2 is connected to the outlet of the compressor 143 through the second refrigerant Is longer than the pipe 145b. The third refrigerant pipe 145c connecting the outlet of the condenser 142 and the expansion valve 144 and the fourth refrigerant pipe 145d connecting the outlet of the expansion valve 144 and the evaporator 141 are connected to the second And is shorter than the refrigerant pipe 145b.

The first refrigerant pipe 145a and the second refrigerant pipe 145b may each include a bent portion 146 to absorb at least a part of the vibration generated in the compressor 143. [

The bent portion 146 includes a plurality of vertical tubes 146a vertically spaced apart at regular intervals and a plurality of U-shaped connecting tubes 146b connecting the respective vertical tubes 146a. The bent portion 146 may have a maximum height between the two connection pipes 146b and a ratio of the width between two adjacent straight pipes 146a, for example, 4 to 1, according to a design standard. This ratio is only one example and is not limited to this. As the number of bending of the bending portion 146 increases, the amount of vibration absorption increases. However, as the bending length increases, interference between the bending portion 146 and peripheral components can not be avoided. It is preferable to minimize the length.

(The supporting portion 151: part supported by the heat exchanger) of the refrigerant pipe 145 connected to the compressor 143 and the other end of the refrigerant pipe 145 connected to the heat exchanger The larger the amplitude in the middle portion of the refrigerant pipe 145 becomes.

The third and fourth coolant pipes 145c and 145d whose lengths are connected to the heat exchanger or the expansion valve 144 are not directly connected to the compressor 143, The third and fourth refrigerant pipes 145c and 145d do not need separate bending portions 146 and intermediate holders 150 because the vibrations of the third and fourth refrigerant pipes 145c and 145d are not transmitted. The second refrigerant pipe 145b is relatively shorter in length than the first refrigerant pipe 145a so that the amplitude due to the vibration is not large and the shock transmitted to the support portion 151 of the second refrigerant pipe 145b It is not necessary to provide a separate holder for supporting the piping in the middle. However, a holder (not shown) may be provided according to an increase in the size of the cabinet or an interval between the compressor 143 and the heat exchanger.

The present invention includes a holder 150 in the middle of a relatively long refrigerant pipe among a plurality of refrigerant pipes 145. The holder 150 shown in FIG. 2 is provided in the first refrigerant pipe 145a.

The holder 150 is provided in the middle of the vibration transmitted from the compressor 143 along the refrigerant pipe 145.

The holder 150 may be integrally formed with the heat exchanger cover 103 and the heat exchanger accommodating portion 102 or may be separately provided in the base 101. [

2 is a perspective view showing a state where the holder 150 shown in FIG. 2 is integrally formed with the heat exchanger cover 103 and the accommodating portion 102. FIG. 3 is an enlarged view of the holder 150 .

The intermediate holder 150 may include a support portion 151 and a pressing portion 152.

The support portion 151 supports the refrigerant pipe 145. A receiving groove 151a is provided in the support portion 151 to support the refrigerant pipe 145. [ The receiving groove 151a may have the same shape as the outer shape of the refrigerant pipe 145 in order to increase the adhesion with the refrigerant pipe 145. For example, circular or semicircular. A part of the portion extending to one side of the heat exchanger cover 103 from the middle portion of the refrigerant pipe 145, for example, the bent portion 146, is accommodated in the semicircular receiving groove 151a. The receiving groove 151a may cover at least a part of the refrigerant pipe 145 so that the refrigerant pipe 145 may be seated on the supporting part 151. [

The pressurizing portion 152 pressurizes and fixes the refrigerant pipe 145. A pressing projection 152b is provided on the inner surface of the pressing portion 152 to press the refrigerant pipe 145. [ At least two or more pressing protrusions 152b may be formed on the lower surface of the pressing portion 152 to press the outer circumferential surface of the refrigerant pipe 145.

3 may protrude laterally from one side of the heat exchanger accommodating portion 102 and may be integrated with the heat exchanger accommodating portion 102. [ For example, when the heat exchanger accommodating portion 102 is manufactured, the support portion 151 may be formed into a metal mold. Thus, the support portion 151 is formed as a part of the heat exchanger accommodating portion 102, not a separate component, so that the support 151 is easy to manufacture.

The pressing portion 152 may protrude laterally from one side of the heat exchanger cover 103 and may be integrated with the heat exchanger cover 103. For example, when manufacturing the heat exchanger cover 103, the pressing portion 152 may also be formed into a metal mold. As a result, the pressing portion 152 is formed as a part of the heat exchanger cover 103 instead of a separate component, so that the manufacturing and the operation are convenient.

For example, when the supporting portion 151 and the pressing portion 152 are made of separate components from the heat exchanger accommodating portion 102 and the cover 103, the number of manufacturing steps is increased and a separate installation space is required for the base 101 , The number of components increases, and the number of assembly operations increases. However, when the heat exchanger accommodating unit 102 and the cover 103 and the holder 150 are integrally formed, the manufacturing process is shortened and a separate installation space for the holder 150 is removed from the base 101 Which is advantageous in terms of space utilization, the number of parts is reduced, and the number of assembly passages is reduced.

The pressing portion 152 includes a plurality of reinforcing ribs 153 so that the supporting force and the pressing force can be further secured from the heat exchanger cover 103 when the heat exchanger cover 103 and the heat exchanger cover 103 are integrally combined.

The reinforcing ribs 153 protrude laterally from one side of the heat exchanger cover 103 and are spaced apart along the side surface of the heat exchanger cover 103. The reinforcing ribs 153 may be integrally formed by extending the lower end of the reinforcing ribs 153 to the same width as the upper surface of the pressing portion 152. [ The reinforcing ribs 153 may be connected by connection ribs 154 extending downward from one side of the heat exchanger cover 103. By the connecting rib 154 and the reinforcing rib 153 extending from the side of the heat exchanger cover 103, the pressing portion 152 increases the contact area connected to the heat exchanger cover 103 to further expand the supporting force . The pressing portion 152 and the supporting portion 151 may be coupled together when the heat exchanger cover 103 is coupled to the upper portion of the heat exchanger without separately assembling the pressing portion 152 and the supporting portion 151. [

4 is a cross-sectional view of one side of the holder 150 of FIG.

4, the supporting portion 151 includes a contact portion 151b, an inlet portion 151c, and a seating portion 151d.

The contact portion 151b has a semi-circular receiving groove 151a to support and support a part of the refrigerant pipe 145 to prevent the refrigerant pipe 145 from moving in the lateral direction (left and right direction) and downward.

The inlet portion 151c is extended upward from the contact portion 151b to form an opening for insertion of the refrigerant pipe 145. [

The seating portion 151d is horizontally extended laterally at the entrance portion 151c to allow a portion of the pressing portion 152 to be seated.

4, the pressing portion 152 is composed of an upper cover 152a and a pressing protrusion 152b.

The upper cover 152a may be connected to the reinforcing rib 153 and the connecting rib 154 to be supported.

The upper cover 152a may include a depressed portion formed to be recessed at an intermediate portion and a cover extended portion seated at the upper surface of the seating portion 151d of the supporting portion 151 on both sides of the depressed portion. The depressed portion is inserted into the inlet portion 151c of the support portion 151. One end of the cover extension portion is integrally formed with the connection rib 154 to connect the connection rib 154 and the pressing portion 152.

The pressing projection 152b extends downward from the depression of the upper cover 152a to press the refrigerant pipe 145. [ The pressure protrusions 152b are protruded to be spaced apart from each other in the right and left direction in the depressed portion and can be symmetrically arranged in both directions from the vertical center line of the refrigerant pipe 145. [ The pressing projection 152b can be extended continuously in the longitudinal direction of the depressed portion.

According to the configuration of the holder 150, the holder 150 can be assembled by coupling the heat exchanger cover 103 with the heat exchanger accommodating portion 102, which is a part of the base 101.

When the heat pump system 140 such as the base stator compressor 143, the heat exchanger and the refrigerant pipe 145 is mounted, the refrigerant pipe 145 is inserted into the holder 150 and then the heat exchanger cover The refrigerant pipe 145 can be firmly fixed while covering the refrigerant pipe 103.

The operation of the holder 150 will be described in more detail.

Since the heat exchanger cover 103 is a heavy body, the pressing force applied to the holder 150 is sufficient even by the weight of the cover itself. For example, the pressing portion 152 and the supporting portion 151 do not need a fastening means such as a bolt.

The pressing force by the weight of the heat exchanger cover 103 is transmitted to the upper cover of the pressing portion 152 through the reinforcing rib 153 and the connecting rib 154. [ The pressing protrusions 152b formed on the bottom surface of the depressed portion can uniformly apply the pressing force to the both sides of the upper portion of the refrigerant pipe 145 at the same time, with a distributed load centering on the vertical center line of the refrigerant pipe 145 at the same time. The refrigerant pipe 145 that is stably supported in the receiving groove 151a of the support portion 151 can be fixed in the lateral direction as well as the up and down directions by receiving a pressing force from the pressing protrusion 152b.

Therefore, according to the present invention, by fixing the middle portion of the refrigerant pipe 145 that is long in the refrigerant pipe 145 extending from the compressor 143 to the heat exchanger using the holder 150, the vibration of the compressor 143 is blocked It is possible to prevent damage such as cracks on the welded portion of the refrigerant pipe 145 coupled with the heat exchanger.

In addition, the durability problem of the refrigerant pipe 145 can be solved thereby.

The pressing portion 152 and the supporting portion 151 of the holder 150 are integrally formed together with the heat exchanger cover 103 and the heat exchanger accommodating portion 102 so that the holder 150 is manufactured as a separate component It is possible to reduce the number of parts and the number of manufacturing steps compared with the case, and to save space for the holder 150, thereby improving the space usability. In addition, since the pressing portion 152 and the support portion 151 are assembled together with the heat exchanger cover 103, it is possible to reduce the number of assembling steps for assembly and disassembly of the holder 150. This simplifies manufacture and installation.

5 is a sectional view showing another embodiment of the holder 250 according to the present invention.

The holder 250 shown in FIG. 5 is composed of a pressing portion 252 and a supporting portion 251.

4, the pressing portion 252 and the heat exchanger cover may be connected to each other, or may be integrally formed.

Although the supporting portion 251 does not separately show the coupling relation with the heat exchanger accommodating portion, it is also possible to connect the supporter 251 and the heat exchanger accommodating portion to each other or to manufacture them integrally with reference to FIG.

Other configurations of the pressing portion 252 and the supporting portion 251 are similar to those described in FIG. 4, and therefore, a detailed description thereof will be omitted.

The support portion 251 shown in Fig. 5 has the vibration absorbing plate 255 therein. The vibration absorbing plate 255 may be made of an elastic material such as rubber and the vibration absorbing plate 255 may be bent into a circular or semicircular shape and inserted into the receiving groove of the supporting portion 251. Since the vibration absorbing plate 255 covers a part of the refrigerant pipe 145a, the adhesion with the refrigerant pipe 145a can be enhanced. Thereby, the vibration transmitted from the compressor to the refrigerant pipe 145a can be attenuated.

The pressing projection 252b of the pressing portion 252 shown in Fig. 5 further includes a vibration absorbing member 256 attached to the lower end portion. The vibration absorbing member 256 is made of an elastic material and can uniformly transmit the pressing force from the heat exchanger cover to both sides of the upper portion of the refrigerant pipe 145a. Further, the vibration transmitted from the compressor along the refrigerant pipe 145a can be attenuated.

The above-described clothes processing apparatus is not limited to the configuration and method of the above-described embodiments, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications may be made.
