When the shape of the outside air suction unit 322 is provided as described above, outside air can be introduced into the duct body 321 more effectively.

The circulation duct 320 may be provided with an outside air damper 373 that opens and closes the outside air suction unit 322 . Through the opening and closing of the outside air damper 373, the introduction of outside air into the circulation duct 320 may be allowed or blocked.

The control unit installation unit 313 may be provided in the shape of a duct open to either the front or the rear at the bottom of the circulation duct 320 .

The structure of the controller installation unit 313 will be described later.

6 shows the circulation duct structure of the laundry treatment apparatus of the present invention.

The circulation duct 320 may extend upward from the bottom of the base to form a flow path through which air flows. The circulation duct 320 may include a heat exchanger installation part 3212 providing a space in which the evaporator 341 and the condenser 343 are installed. The heat exchanger installation part 3212 may be provided inside the duct body 321 .

The duct body 321 may be provided with an open upper surface. The condenser 343 and the evaporator 341 may be introduced and installed through the opening of the duct body 321 .

An opening of the duct body 321 may be shielded by the base cover 360 , and the base cover 360 and the duct body 321 may form a flow path of the circulation duct 320 .

The front surface of the duct body 321 may be spaced apart from the front end of the base bottom part 311 to the rear.

Thus, the base bottom part 311 can secure a support surface 3111 on which at least one of the aforementioned water supply container 301 or drainage container 302 and the outdoor air duct 370 is installed and supported.

Meanwhile, the heat supply unit 340 includes an evaporator 341 provided as a heat exchanger installed inside the circulation duct 320 to cool and dehumidify the air introduced into the circulation duct 320, and the evaporator 341. A condenser 343 provided as a heat exchanger that heats the passing air to form hot air, and a compressor 342 disposed outside the circulation duct 320 and supplying a refrigerant that exchanges heat with the air to the condenser 343 , An expansion valve 344 for cooling by expanding the refrigerant passing through the condenser 343 may be included.

Meanwhile, as the duct body 32 is integrally molded to the base part 310, a higher height of the heat exchanger installation part 3212 can be secured, and the heights of the condenser 343 and the evaporator 341 can also be increased. can be increased

As a result, the widths of the condenser 343 and the evaporator 341 in the front-back direction can be reduced, so that the number of refrigerant pipes passing through the condenser and the evaporator can be reduced. Accordingly, there is an effect of reducing the flow loss of air passing through the condenser and the evaporator.

Meanwhile, the sum of the longitudinal length of the evaporator 341 and the longitudinal length of the condenser 343 may be smaller than the length of the heat exchanger installation part 3212 . Accordingly, the length of the heat exchanger installation part 3212 in the front-rear direction may be equal to or less than half of the length of the duct body 321 .

Therefore, since the heat exchanger installation part 3212 can be sufficiently spaced from the outside air intake part 322, a sufficient space is provided in the circulation duct 320 to allow the outside air and the air inside the inner case 200 to flow in. can be secured

Meanwhile, the inside of the duct body 321 may include an installation partition 3211 dividing the heat exchanger installation part 3212 and the outside of the heat exchanger installation part 3212 . The installation partition wall 3211 may protrude from a side surface of the duct body 321 and may be provided to support the front side of the evaporator 341 .

In addition, the duct body 321 may be expanded in width based on the installation partition wall 3211 and extended rearward.

As a result, the width of the heat exchanger installation part 3212 may be greater than half of the width of the base part 310 . Also, the width of the circulation duct 320 may be greater than half of the width of the base part 310 .

The width of the condenser 343 and the width of the evaporator 341 may also be greater than half of the total width of the base part 310 .

As described above, when the widths of the condenser 343 and the evaporator 341 are secured, a sufficient heat exchange capacity can be secured.

In addition, the fan installation unit 350 may be disposed to overlap the condenser 343 or the evaporator 341 in the forward and backward directions. Accordingly, air passing through the evaporator 341 and the condenser 343 may flow into the fan housing 351 without bending the flow path. That is, in the process of moving the air introduced into the circulation duct 320 to the fan housing 351, there is no bending of the flow path, thereby minimizing flow loss.

7 explains the shape of the circulation duct of the laundry treatment apparatus of the present invention.

In the base part 310, the base bottom part 311 and the circulation duct 320 may be integrally molded through mold injection.

The mold forming the inner surface of the duct body 321 may be removed by being pulled out from the inside of the duct body 321 in an upward direction. At this time, to facilitate the withdrawal of the mold, the wall surface of the duct body 321 may be inclined at a predetermined angle with respect to the removal direction of the mold.

The width of the lower surface 321a of the duct body 321 may be shorter than the width of the upper surface 321b of the duct body 321 .

Specifically, the distance between the walls of the duct bodies 321 facing each other may increase as the distance from the base bottom part 311 increases. The distance between the left side and the right side of the circulation passage facing each other may be increased along the withdrawal direction of the mold. Accordingly, removal of the mold may be facilitated.

On the other hand, the air discharge unit 323 extends from the rear of the duct body 321 to have a smaller diameter or width and extends from the air extension tube 3231 in a pipe shape having a uniform diameter to the inside. An air discharge pipe 3232 forming a hollow 3233 may be included. The air extension tube 3231 can perform the function of a nozzle and can increase the speed of the discharged air.

The inner diameter of the air discharge pipe 3232 may increase as it moves away from the duct body 321 . A change in the inner diameter of the air discharge pipe 3232 may be caused by a mold removal direction. Conversely, it can be seen that mold removal is facilitated by the change in the inner diameter.

In addition, the mold forming the air discharge part 323 can be removed as shown in the above drawing. After being drawn forward from the inside of the air discharge unit 323 toward the inside of the circulation duct 320, it may be removed toward the upper open surface of the circulation duct 320. In this process, the mold can be formed into a structure that is easy to withdraw.

8 is a cross-sectional view of the circulation duct.

The installation partition wall 3211 may protrude inward from the inner wall of the duct body 321 or may be formed by recessing the outer wall of the circulation duct toward the inside.

The heat exchanger installation part 3212 may be formed between the heat exchanger installation partition wall 3211 and the air discharge part 323 .

The mold for forming the air discharge part 323 may be drawn out to the front of the air discharge part 323 and then removed upward. It is necessary to prevent the mold forming the air discharge part 323 from interfering with the heat exchanger installation partition wall when being drawn forward from the inside of the air discharge part 323 . To this end, design values of the air discharge unit 323 may be adjusted.

Specifically, when molding the air discharge unit 323, a mold for forming the front side and a mold for forming the rear side based on the parting line 3233 of the air discharge unit 323 in the drawing may be provided separately. there is. Accordingly, the removal directions of the molds may also be different from each other. The mold for forming the part located in the front of the air discharge unit 323 based on the parting line is drawn forward, and the mold for forming the part located at the rear of the air discharge unit 323 based on the parting line is drawn backward. It can be.

That is, in order to prevent the mold being drawn forward from interfering with the heat exchanger installation partition wall during the drawing process, the distance 1 (323a) may be smaller than the distance 2 (321c) in the drawing. Distance 1 (323a) may mean a distance between the parting line of the air discharge unit 323 and the front end of the air discharge unit 323. Also, distance 1 (323a) may mean a distance between the parting line of the air discharge unit 323 and the rear opening of the circulation duct. The distance 2 (323c) may mean a distance between the front end of the air discharge unit 323 and the heat exchanger installation partition. In addition, the distance 2 (323c) may mean a distance between the rear opening of the circulation duct and the heat exchanger installation partition wall 3211.

The drain pipe 3263 may be disposed on an inner surface of the water reservoir 326 rather than on an outer surface thereof.

The bottom surface 3261 of the water reservoir may have a slope lowering toward the inside of the circulation duct 320 based on the bottom surface of the base part 310 .

15 is an exploded perspective view of a circulation duct, a base part, and a base cover of a laundry treatment apparatus according to an embodiment of the present invention.

Referring to FIG. 15 , the laundry treatment apparatus according to an embodiment of the present invention includes a base part 310 disposed under a machine room 300 and providing a space in which a compressor 342 is installed. In addition, the laundry treatment apparatus according to an embodiment of the present invention includes a circulation duct 320 extending from the base part 310 to provide a space in which the evaporator 341 and the condenser 343 are installed. The circulation duct 320 provides a passage through which air in the laundry treatment space 220 circulates.

The circulation duct 320 may be formed in such a way as to extend upward from the base part 310 . That is, the circulation duct 320 may be integrally formed with the base portion 310 . The circulation duct 320 and the base part 310 may be injection molded through a mold. That is, the base part 310 and the circulation duct 320 may be made of a material used for injection such as synthetic resin or plastic.

The circulation duct 320 and the base part 310 as a whole may be defined as a base molding (M). The base molding M may be formed of various materials including injection molding. If there is no separate fastening between the circulation duct 320 and the base portion 310, it can be understood that the circulation duct 320 and the base portion 310 constitute the base molding M.

As the base part 310 and the circulation duct 320 are integrally formed, it is possible to prevent air from leaking inside the circulation duct 320 . The circulation duct 320 and the base part 310 may be connected to each other without a separate connecting member. Thus, the circulation duct 320 can be more firmly supported by the base part 310 .

In addition, as the base part 310 and the circulation duct 320 are integrally formed, the height of the circulation duct 320 may be increased. As the height of the circulation duct 320 increases, the heights of the evaporator 341 and the condenser 343 may increase. As the heights of the evaporator 341 and the condenser 343 increase, widths of the evaporator 341 and the condenser 343 in the forward direction may decrease. Since the height is increased, the designed heat exchange effect can be generated even if the width is reduced.

As the front and rear widths of the evaporator 341 and the condenser 343 are reduced, flow loss of air passing through the evaporator 341 and the condenser 343 may be reduced. Accordingly, the overall efficiency of the laundry treatment apparatus may be improved.

In addition, when the circulation duct 320 extends from the base portion 310 and is integrally formed with the base portion 310, a process of separately assembling the circulation duct 320 on the base portion 310 is not required. .

In addition, the circulation duct 320 may include a duct opening 324 formed by opening the upper side of the duct body 321 . That is, the duct body 321 may form a side surface of the circulation duct 320 . The duct body 321 extends to form a side wall of the passage, and may have a duct opening 324 opened at the upper side.

An evaporator 341 and a condenser 343 may be inserted through the duct opening 324 . The evaporator 341 and the condenser 343 may be installed inside the circulation duct 320 through the duct opening 324 . The duct body 321 may be disposed to surround the evaporator 341 and the condenser 343 .

When the duct body 321 is integrally formed with the base part 310 , the evaporator 341 and the condenser 343 may be more stably positioned inside the duct body 321 . In addition, leakage of air passing through the evaporator 341 and the condenser 343 can be prevented.

A base cover 360 for shielding at least a portion of the duct opening 324 may be coupled to an upper side of the duct body 321 . The base cover 360 may form a passage through which air circulates together with the duct body 321 .

The base cover 360 includes a shielding body 363 that shields a portion of the duct opening 324, and an inlet body extending from the shielding body 363 to communicate the circulation duct 320 and the laundry treatment space 220. (361). The base cover 360 may include an inlet 362 formed on the inlet body 361 and through which air passes.

Meanwhile, the inlet body 361 may be disposed in front of the evaporator 341 . That is, the inlet body 361 may be located in a direction away from the condenser 343 based on the evaporator 341 .

The shielding body 363 may be disposed to overlap the evaporator 341 or the condenser 343 in a height direction. Meanwhile, the inlet body 361 extends forward from the shielding body 363 and may be spaced apart from the evaporator 341 or the condenser 343 in the front-back direction.

When the inlet body 361 and the evaporator 341 are arranged as above, the air introduced into the circulation duct 320 through the inlet body 361 does not immediately come into contact with the evaporator 341, but the circulation duct ( 320) The inner space can be fluidized.

That is, the air introduced into the circulation duct 320 through the inlet body 361 may be guided to pass through the empty space inside the circulation duct 320, the evaporator 341, and the condenser 343 sequentially. Therefore, there is an effect that the heat exchange efficiency of air can be increased.

Meanwhile, the base part 310 may include a base bottom part 311 forming a support surface. The circulation duct 320 may extend upward from the bottom part 311 of the base. In addition, the duct body 321 may extend upward from the bottom part 311 of the base.

At least one of the above-described water supply container 301 and drainage container 302 may be disposed above the bottom part 311 of the base.

Meanwhile, the circulation duct 320 may include an installation partition wall 3211 protruding from the inner wall of the duct body 321 . The installation partition 3211 may be disposed in front of the evaporator 341 and the condenser 343 .

The installation partition wall 3211 may concentrate the air inside the duct body 321 toward the evaporator 341. In other words, it is possible to prevent air from escaping to one side of the evaporator 341 . The installation partition wall 3211 can improve heat exchange efficiency inside the duct body 321 .

Meanwhile, the base part 310 may include a compressor installation part 312 providing a space in which the compressor 342 is installed. The compressor installation part 312 may be formed on the bottom part 311 of the base. The compressor installation part may be integrally formed with the base part 310 . The compressor installation part 312 may protrude from the bottom part 311 of the base.

That is, when manufacturing the base part 310 and the circulation duct 320, the compressor installation part 312 may also be manufactured together. For example, the compressor installation part 312 may be formed on the base part 310 using a mold.

16 is a top view of a circulation duct and a base part according to an embodiment of the present invention.

Referring to FIG. 16 , the duct body 321 may be spaced apart from the front end of the base portion 310 to the rear. That is, the duct body 321 may be spaced apart from the front end of the base bottom part 311 to the rear.

As the duct body 321 is spaced apart from the front end of the base part 310 to the rear, there is an effect that the front space of the base part 310 can be utilized more efficiently.

Meanwhile, the circulation duct 320 may further include an air discharge unit 323 extending from the duct body 321 and guiding air to the outside of the circulation duct 320 . The air outlet 323 may extend from the duct body 321 to communicate with the rear wall of the duct body 321 . The air outlet 323 may have a smaller width than the duct body 321 .

In addition, the circulation duct 320 may be disposed to overlap at least a portion of the compressor installation part 312 in the front-back direction. In particular, the right side of the circulation duct 320 may be overlapped with the left side of the compressor installation part 312 in the front-back direction. In other words, the circulation duct 320 may overlap at least a portion of the compressor 342 in the front-back direction.

In addition, the circulation duct 320 may be disposed to overlap at least a portion of the compressor installation part 312 and the base part 310 in the width direction. The air discharge unit 323 may be disposed to overlap the compressor installation unit 312 in the width direction.

In the conventional clothes handling apparatus, since the space occupied by the compressor on the base is large, a component corresponding to the circulation duct is disposed above the compressor. That is, it is difficult to overlap the circulation duct and the compressor in the width direction or in the front-back direction.

However, in the laundry treatment apparatus according to an embodiment of the present invention, the size of the compressor is changed. Accordingly, a space occupied by the compressor 342 on the base portion 310 may be reduced. Therefore, the circulation duct 320 may be overlapped with the compressor 342 or the compressor installation unit 312 in the front-back direction. In addition, the circulation duct 320 may be disposed to overlap the compressor 342 or the compressor installation part 312 and the base part 310 in the width direction.

As a result, there is an effect that components such as the compressor 342 can be more compactly arranged on the base part 310 . That is, as space utilization increases, there is an effect of further expanding the laundry treatment space 220 .

17 is a cross-sectional view of a circulation duct and a base part cut in a plane perpendicular to the front-back direction according to one embodiment of the present invention. 17 shows a cross section of a portion of the circulation duct cut in a plane parallel to the ground.

The controller installation part 313 and the water storage part 326 may be overlapped in the width direction of the cabinet 100 . In addition, the circulation duct 320 may be overlapped with the controller installation unit 313 in the height direction of the cabinet 100 . In particular, the bottom surface 325 of the circulation duct may be overlapped with the controller installation unit 313 in the height direction of the cabinet 100 .

Meanwhile, the mold forming the inner surface of the circulation duct may be removed in a direction drawn toward the duct opening 324 . Accordingly, the width of the duct body 321 may increase as the distance from the base part 310 increases. When the width of the duct body 321 increases in the upward direction, it may be easy to remove the mold.

Referring to FIGS. 17 and 7 together, the lower surface 321a of the duct body may be shorter than the upper surface 321b of the duct body. In other words, the distance between the inner walls facing each other among the inner walls of the duct body 321 may increase upward. In addition, the distance between inner walls facing each other among the inner walls of the duct body 321 may increase along the extension direction of the duct body 321 . That is, the distance between the inner walls facing each other among the inner walls of the duct body 321 may increase as the distance from the base part 310 increases.

In addition, the duct body 321 may be inclined upward toward the outside of the duct body 321 along the extension direction of the duct body 321 . In other words, the inner walls of the duct body 321 may be provided to be farther apart from each other toward the upper side. In particular, the distance between the inner walls of the duct body 321 facing each other may increase upward.

Referring to FIG. 17, the direction in which the mold is removed is expressed as “MR”. A direction in which the mold is removed may be a direction perpendicular to the base portion. Also, the direction in which the mold is removed may be the height direction of the cabinet. Also, the direction in which the mold is removed may mean a direction parallel to the direction of gravity.

In addition, the angles formed by the direction in which the mold is removed and the inner wall of the duct body 321 are shown as “m1” and “m2”.

A left inner wall of the duct body 321 may be provided to form a first body angle m1 with the mold removal direction MR. The first body angle m1 may mean an angle provided so as to incline toward the outside of the duct body 321 as the distance from the bottom surface 325 of the circulation duct increases.

The right inner wall of the duct body 321 may be provided to form a second body angle m2 with the mold removal direction MR. The second body angle m2 may mean an angle provided so as to incline toward the outside of the duct body 321 as the distance from the bottom surface 325 of the circulation duct increases.

That is, the first body angle m1 and the second body angle m2 may form angles in different directions. The mold forming the left inner wall and the right inner wall of the duct body 321 can be easily removed by the first body angle m1 and the second body angle m2.

In addition, the right inner wall of the water reservoir 326 may be formed by the right inner wall of the duct body 321 . However, the left inner wall of the water reservoir 326 may be separately formed by a mold. The water reservoir side surface 3265 forming the left inner wall of the water reservoir 326 may form a third body angle m3 with the mold removal direction MR. The third body angle m3 may refer to an angle at which the side surface 3265 of the water storage part moves upward and away from the outside of the water storage part 326 along a direction away from the base part 310 .

In other words, the third body angle m3 may form an inclination in the same direction as the first body angle m1. Also, the third body angle m3 may form an inclination in a direction different from that of the second body angle m2. When the third body angle m3 and the second body angle m2 have different inclinations, the mold forming the water reservoir 326 can be more easily removed.

Also, as described above, the installation partition wall 3211 may be formed to protrude from the inner wall of the duct body 321 . In addition, the installation partition wall 3211 may be formed in such a way that the outer wall of the duct body 321 is depressed toward the inside of the duct body 321 .

At this time, the mold forming the installation partition wall 3211 is introduced from the outside of the duct body 321 toward the inside of the duct body 321, and when the mold is removed, the mold of the duct body 321 It can be drawn outward.

In other words, the mold forming the inner surface of the installation partition wall 3211 may be removed upward, and the mold forming the outer surface of the installation partition wall 3211 may be removed in the width direction of the base portion 310 .

At this time, the installation partition wall 3211 may form a predetermined angle with the mold removal direction so that the mold forming the installation partition wall can be easily removed.

First, the mold forming the inner surface of the installation partition wall 3211 may be removed in the height direction of the cabinet 100 . Accordingly, the inner surface of the installation partition wall may form a fourth body angle m4 with the mold removal direction MR. The fourth body angle m4 may mean an angle inclined upward toward the duct body 321 where the installation partition wall 3211 is formed with respect to the mold removal direction MR.

In other words, the installation partition wall 3211 may be provided such that its cross-sectional area decreases toward the upper side. That is, the fourth body angle m4 may mean an angle that decreases as the cross-sectional area of the installation bulkhead 3211 parallel to the ground extends upward.

As the fourth body angle m4 is formed, the mold forming the inner surface of the installation partition wall 3211 can be more easily removed.

Meanwhile, the mold forming the outer surface of the installation partition wall 3211 may be removed along the width direction of the base part 310 . An outer wall of the installation partition wall 3211 may form a fifth body angle m5 with the mold removal direction MR.

The fifth body angle m5 may refer to an angle at which a distance between outer surfaces of the installation bulkhead 3211 facing each other increases along the mold removal direction MR.

In addition, the length of the installation partition wall 3211 perpendicular to the direction in which the installation partition wall 3211 is recessed may decrease along the direction in which the installation partition wall 3211 is recessed. In other words, the length of the installation partition wall 3211 perpendicular to the mold removal direction MR may be increased along the mold removal direction MR.

When the fifth body angle m5 is formed in the above-described form, the mold forming the outer surface of the installation partition wall 3211 can be more easily removed.

The direction or inclination direction of the above-described body angles (m1, m2, m3, m4, m5) is not limited to the above-described example, and the inclination direction may be changed in a direction in which the mold forming each component is more easily removed. .

As described above, when the body angles (m1, m2, m3, m4, m5) are formed, the mold forming the circulation duct 320 can be more easily removed, and the effect of reducing defects in the circulation duct There will be.

In addition, as the mold is easily removed, the quality of the inner and outer surfaces of the circulation duct 320 can be improved, and overall air flow can be smoothed.

The air discharge unit 323 may be defined as an air discharge pipe 3232 on the rear side and an air extension pipe 3231 on the front side based on the air discharge pipe parting line 3236 .

That is, since the mold removal directions of the air extension pipe 3231 and the air discharge pipe 3232 are different from each other, the diameter gradients of the air extension pipe 3231 and the air discharge pipe 3232 may also be different. In particular, the inner diameter gradients of the air extension pipe 3231 and the air discharge pipe 3232 may be different.

In general, the inner diameter may mean the inner diameter of the pipe shape. That is, it may mean the diameter of a tubular shape. However, the air extension pipe 3231 may be provided in a bell mouth shape rather than a cylindrical pipe shape. Therefore, in this specification, the inner diameter may be understood to mean the cross-sectional area of the passage through which air flows.

In other words, the inner diameter in this specification may be understood to mean the height or width of a section perpendicular to the direction in which air flows or the direction in which the tube extends. That is, when the passage through which the air moves is cut in a plane perpendicular to the forward and backward directions, the width or height of the cut surface of the passage may be referred to as an inner diameter.

The inner diameters of the air extension pipe 3231 and the air discharge pipe 3232 may be formed to increase along the mold removal direction.

Meanwhile, the inner diameter D3 of the air discharge pipe may be increased as the distance from the duct body 321 increases. That is, the inner diameter D3 of the air discharge pipe 3232 may increase along the extension direction.

In summary, the air discharged from the duct body 321 moves along the air extension tube 3231 whose inner diameter narrows along the flow direction, and the flow rate may increase. In addition, the air passing through the air extension pipe 3231 may be discharged to the outside of the circulation duct 320 through the air discharge pipe 3232 whose inner diameter gradually increases.

That is, the air discharged from the duct body 321 may be discharged from the circulation duct 320 as the air flow rate increases and then the air flow rate decreases. There is an effect of reducing the flow loss of air by the above-described shape.

In addition, the gradient formed between the inner surface of the air extension pipe 3231 and the extension direction of the air extension pipe 3231 is the gradient formed between the inner surface of the air discharge pipe 3232 and the extension direction of the air discharge pipe 3232.

It may be formed differently from the direction and the forming gradient 3232r.

In particular, the gradient 3231r of the air extension tube and the gradient 3232r of the air discharge tube may be formed in different directions. In particular, the direction of the gradient may be reversed around the air discharge pipe parting line 3236.

Referring to FIG. 22 together with FIG. 8 , distance 1 (323a), which is the longitudinal length of the air extension pipe 3231, may be smaller than distance 2 (323c), which is the longitudinal length of the heat exchanger installation part 3212. there is.

After the mold forming the air extension tube 3231 is drawn out toward the front, it can be removed by moving upward. That is, the mold forming the air extension pipe 3231 may be drawn forward and moved upward while located inside the duct body 321 to be removed.

At this time, when the distance 1 (323a) is greater than the distance 2 (323c), removal of the mold forming the air extension pipe 3231 may be interfered with. Therefore, when the distance 1 (323a) is greater than the distance 2 (323c), there is an effect of enabling manufacturing using a mold.

In addition, a distance 1 (323a), which is the length of the air extension pipe 3231 in the front-back direction, may be smaller than the distance between the installation partition wall and the air extension pipe. The distance between the installation partition wall 3211 and the air extension pipe 3231 may mean the same distance as the distance 2 (323c). In addition, when provided as described above, there is an effect of facilitating the manufacture of the air extension pipe 3231 using a mold.

Meanwhile, the installation partition wall 3211 may be provided to partially support the front surface of the evaporator 341 . That is, the installation partition wall 3211 can prevent air from flowing into one side of the evaporator 341 . Accordingly, it is possible to prevent air passing through the evaporator 341 from leaking out to the side of the evaporator 341 without sufficient heat exchange. That is, the installation partition wall 3211 has an effect of improving heat exchange efficiency of the evaporator 341 .

As the base part 310 and the circulation duct 320 are integrally formed, and the compressor installation part 312 is integrally formed with the base part 310, the compressor installation part 312 is the air of the circulation duct 320. It may overlap with the discharge part 323 in the width direction.

When the air discharge unit 323 overlaps the compressor 342 in the width direction, there is an effect that the limited space of the machine room can be utilized more effectively.

Also, the air discharge unit 323 may be disposed to overlap at least a portion of the control unit 700 in the height direction of the cabinet 100 . Since the controller installation unit 313 may be disposed under the circulation duct 320, the controller 700 may also be disposed in the height direction with the air discharge unit 323.
