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 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.

19 shows the structure of an outside air duct.

Referring to FIG. 19 (a), the outside air duct 370 may be coupled to the base part 310.

The outside air duct 370 may be provided in communication with the outside air suction unit 322 .

The outdoor air duct 370 includes an outdoor damper 373 that opens and closes the outdoor air intake unit 322 and an outdoor drive unit that rotates the outdoor air intake unit 322 to selectively open and close the outdoor air intake unit 322 ( 374) may be included.

The intake duct 371 may extend from a lower portion of the extension duct 372, and a water supply container 301 and a drainage container 302 may be disposed at the upper portion. The water supply container 301 and the drain container 302 may be coupled to or seated on the intake duct 371 .

The intake duct 371 may include an outdoor air intake 3711 at one end or a free end and a partition rib 3712 provided to partition the outside air 3711.

The outdoor outlet 3711 may be disposed lower than the door 400 so as not to be shielded by the door 400 .

The partitioning ribs 3712 may be provided to partition the inside of the external outlet 3711 to block foreign substances or the user's body from being introduced.

Referring to FIG. 19(b) , when the outdoor driving unit 374 rotates the outdoor air damper 373 to open the outdoor air suction unit 322, the intake duct 371 and the circulation duct 320 can be intertwined

At this time, when the blowing fan 353 is driven, air outside the cabinet may flow into the circulation duct 320 . When the compressor 342 is driven, the outside air may be dehumidified while passing through the circulation duct 320 and supplied to the inside of the inner case 200 .

The door 400 may further include an outlet for discharging air inside the inner case 200 to the outside and a discharge damper for selectively opening and closing the outlet. The outlet may be provided to face the accommodation space of the inner case 200 .

As a result, the dehumidified air may be discharged through the outlet.

In addition, the outside air may be filtered while passing through the cut-off filter 366 and discharged to the outside of the cabinet 100 again.

20 shows the flow of air flowing through the circulation duct.

Referring to FIG. 20 (a), the outside air damper 373 shields the outside air intake 322, the first damper 3641 opens the first inlet 3621, and the second damper 3642 may be controlled while the second inlet 3622 is shielded.

When the blowing fan 353 is driven, air inside the inner case 200 may flow into the first inlet 3621 and pass through the cut-off filter 366 to be filtered.

When the compressor 342 operates, the air passing through the cut-off filter 366 may be dehumidified and heated while passing through the evaporator 341 and the condenser 343 .

Air passing through the condenser 343 may pass through the fan installation part 350 and be supplied into the inner case 200 .

This state may be a state in which steam is not supplied to the inner case 200 . This is because when steam is supplied to the inner case 200, the moisture wets the cut-off filter 366, and thus the performance of the cut-off filter 366 cannot be guaranteed.

As a result, even when steam is not supplied to the inner case 200, before steam is supplied to the inside of the inner case 200, or even after steam is supplied to the inside of the inner case 200, the humidity is lowered. In this case, the air inside the inner case 200 may pass through the first inlet 3641 and the cut-off filter 366 to filter lint, such as foreign substances.

Referring to FIG. 20 (b) , the outside air damper 373 shields the outside air intake 322, the first damper 3641 blocks the first inlet 3621, and the second damper 3642 may be controlled with the second inlet 3622 open.

When the blowing fan 353 is driven, air inside the inner case 200 may flow into the second inlet 3622 . Since the second inlet 3622 is provided downstream of the cut-off filter 366, the air introduced into the second inlet 3622 may not pass through the cut-off filter 366.

As a result, when steam is supplied to the inner case 200 or when the humidity inside the inner case 200 is very high, the air of the inner case 200 flows into the second inlet 3622. And, it is possible to block exposure of the cut-off filter 366 to moisture by blocking the inflow into the first inlet 3621 .

Referring to FIG. 20(c) , the outside air damper 373 opens the outside air suction part 322, the first damper 3641 shields the first inlet 3621, and the second damper 3642 may be controlled with the second inlet 3622 shielded.

When the blowing fan 353 operates, the air inside the inner case 200 is blocked from flowing into the inlet 362, and only the outside air of the cabinet 100 flows into the circulation duct 320. and pass through the cut-off filter 366. As a result, foreign substances such as fine dust contained in the outside air may be filtered through the cut-off filter 366 .

When the compressor 342 is operated, the air passing through the cut-off filter 366 may be dehumidified while passing through the evaporator 341 and the condenser 343 .

Air passing through the condenser 343 passes through the fan installation part 350 and is supplied to the inside of the inner case 200 to supply fresh hot air to clothes.

At this time, when the door 400 is provided with a device for discharging the air inside the inner case 200 to the outside, the air outside the cabinet passes through the cut-off filter 366 and the heat supply unit 340, It can be discharged in a purified and dehumidified state.

As a result, in the laundry treatment apparatus of the present invention, the control unit 700 controls the outside driving unit 374 and the driving unit 365 to determine flow directions of the air inside the inner case 200 and the air outside the cabinet. there is.

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

Referring to FIG. 21 , 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 backward, an empty space may be formed on the front side of the base bottom part 311 . At least one of the outdoor air duct 370, the water supply container 301, and the drainage container 302 may be disposed in the corresponding space.

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 .

22 is a cross-sectional view of a controller installation unit according to an embodiment of the present invention.

In particular, FIG. 22 shows a cross section of the base portion and the circulation duct cut along a plane perpendicular to the front-back direction from the front side.

The circulation duct according to an embodiment of the present invention may include a circulation duct bottom surface 325 forming a bottom surface of a passage through which air in the laundry treatment space 220 circulates. In addition, the circulation duct 320 may include a water reservoir 326 that is recessed downward from the bottom surface 325 of the circulation duct and collects water condensed in the evaporator 341 .

The controller installation part 313 may be disposed to overlap the water storage part 326 and the base part 310 in the width direction. In addition, one side of the water reservoir 326 may form one side of the controller installation unit 313 .

More specifically, the water reservoir 326 may include a water reservoir side 3265 forming a side surface of a space in which water is collected. The water reservoir side surface 3265 may be formed by the same barrier rib as the control installation part side surface 313c.

In particular, the side opposite to the side surface 313c of the controller installation part may form the side surface 3265 of the reservoir part. The side opposite to the side surface 3265 of the water reservoir may form a side surface 313c of the controller installation part. In other words, one side of the specific barrier rib may form the controller installation portion 313 and the other side may form the water storage portion 326 .

In addition, as described above, the bottom surface of the heat exchanger installation unit 3212 may form the control unit installation unit upper surface 313b. That is, the upper surface of the specific partition wall may form the heat exchanger installation part 3212, and the lower surface of the specific partition wall may form the controller installation part 313.

As described above, by densely arranging the controller installation unit 313 and the water storage unit 326 within a limited space, the space inside the machine room can be utilized more effectively. In addition, since separate parts are not added to form each component, assemblability can be improved. In addition, since the control unit installation unit 313 and the water storage unit 326 are integrally formed on the base unit 310 and the circulation duct 320, water leakage can be prevented.

23 is a detailed illustration of a water storage part among a circulation duct and a base part according to an embodiment of the present invention.

Referring to FIG. 23 , the laundry treatment apparatus according to an embodiment of the present invention is provided inside a machine room 300, accommodates an evaporator 341 and a condenser 343, and provides a passage through which air in the laundry treatment space circulates. It may include a circulation duct 320 and a base portion 310 provided inside the machine room 300 and supporting a lower portion of the circulation duct 320.

In addition, the circulation duct 320 is condensed in the evaporator 341 by condensing the bottom surface 325 of the circulation duct forming the bottom surface of the passage through which the air in the laundry treatment space circulates and one side of the bottom surface 325 of the circulation duct 325 is depressed. It may include a water reservoir 326 in which the collected water is collected.

The water reservoir 326 may be recessed in the bottom surface 325 of the circulation duct and integrally formed with the bottom surface 325 of the circulation duct. That is, a separate component is not combined or added to form the reservoir 326 . Accordingly, it is possible to prevent water leakage from occurring in the water reservoir 326 .

In addition, the water reservoir 326 may be formed together when forming the circulation duct 320 . That is, the mold forming the circulation duct 320 may form the water reservoir 326 .

As described in FIG. 25, the base part 310 and the circulation duct 320 may be integrally formed. That is, the base part 310 and the circulation duct 320 may be integrally formed by a mold. That is, the base part 310 and the circulation duct 320 may constitute a base molding M integrally formed.

Meanwhile, the mold forming the water reservoir 326 may be removed upward. That is, the water reservoir 326 may be inclined with respect to the direction in which the mold forming the water reservoir 326 is removed. The mold forming the water reservoir 326 can be more easily removed by the inclination. Therefore, there is an effect of improving the quality of the water reservoir 326 formed by the mold.

In addition, the water reservoir 326 may be disposed to overlap the evaporator 341 or the condenser 343 in a height direction. In the conventional laundry treatment apparatus 1, a separate space for storing water generated by the evaporator 341 is not provided. However, the present invention has an effect of more effectively collecting water generated in the evaporator 341 and discharging it to the outside by forming the water storage part 326 on the bottom surface 325 of the circulation duct.

As the condensed water is effectively discharged, there is an effect of solving the sanitary problem caused by the remaining condensed water. In addition, when the evaporator 341 and the water reservoir 326 are arranged to overlap in the height direction, the moving line of condensed water generated in the evaporator 341 may be reduced.

Accordingly, it is possible to prevent condensed water from remaining in a location other than the water storage unit 326 to cause hygiene and performance problems.

Meanwhile, the water reservoir 326 may be disposed to overlap the control installation unit 313 and the base unit 310 in the width direction. In particular, when viewed from the front, the water storage unit 326 may be disposed on the right side of the controller installation unit 313.

As described above, when the water storage part 326 and the base part 310 are overlapped in the width direction, the limited space inside the machine room can be utilized more efficiently.

In the case of a conventional laundry treatment apparatus, a separate water storage unit 326 is not provided, and the control unit 700 is also raised and lowered by a supporter separately coupled to the base unit 310. Therefore, it is difficult to arrange the water storage part 326 and the controller installation part 313 to overlap each other in the width direction.

Meanwhile, the water storage unit 326 may be disposed to overlap at least a portion of the compressor installation unit 312 in the front-back direction.

In a conventional laundry treatment apparatus, an evaporator is disposed above a compressor. Accordingly, condensed water generated in the evaporator was also generated on the upper side of the compressor.

However, in the laundry treatment apparatus according to an embodiment of the present invention, the compressor 342 and the evaporator 341 may not be disposed vertically, but may be spaced apart from each other in the front, rear, left, and right directions. Accordingly, the water storage unit 326 and the compressor installation unit 312 may be overlapped in the front-back direction.

As described above, when the compressor installation part 312 and the water storage part 326 are arranged to overlap in the front-back direction, there is an effect that the limited space inside the machine room can be utilized more efficiently.

Meanwhile, a width 326w of the water storage part may be smaller than a width of the compressor installation part 312 . When the width 326w of the water reservoir is excessively large, a space in which residual water can be generated may be expanded. Accordingly, the probability of occurrence of residual water may be reduced by having the width 326w of the water storage portion smaller than the width of the compressor installation portion 312 .

In addition, the width 326w of the water reservoir may be less than half of the width 321w of the duct body. When the width 326w of the water reservoir is larger than half of the width 321w of the duct body, the area where residual water can be generated can be expanded as described above.

Therefore, when the width 326w of the water reservoir is less than half of the width 321w of the duct body, it is possible to reduce the possibility of a sanitary problem.

In addition, the width 326w of the water reservoir may be greater than the width 3211w of the installation bulkhead. When the width 326w of the water reservoir is greater than the width 3211w of the installation bulkhead, water positioned at the rear of the installation bulkhead 3211 may move forward.

The width of the reservoir (326w), the width of the duct body (321w), and the width of the installation bulkhead (3211w) may mean all of the maximum width or minimum width, respectively. In addition, it can be interpreted as meaning a value between the maximum width and minimum width of each.

In addition, the water storage part 326 may include a bottom surface 3261 of the water storage part forming a bottom surface. The bottom surface 3261 of the water reservoir may be spaced apart from the inner case 200 from the bottom surface 325 of the circulation duct. That is, the bottom surface 3261 of the water reservoir may be located lower than the bottom surface 325 of the circulation duct. That is, the bottom surface 3261 of the water reservoir may be disposed closer to the ground than the bottom surface 325 of the circulation duct.

When the water reservoir bottom surface 3261 is located closer to the ground, water located on the circulation duct may be collected into the water reservoir 326 by gravity.

In addition, at least a portion of the installation partition wall 3211 may be located in the water reservoir 326 . That is, the installation partition wall 3211 protrudes from the inner surface of the duct body 321 and may extend upward from the bottom surface 3261 of the water reservoir.

The installation partition wall 3211 is positioned in the water reservoir 326, so that air introduced into the evaporator 341 may be prevented from moving through the water reservoir 326. That is, the installation partition wall 3211 may increase heat exchange efficiency generated in the evaporator 341 .

Meanwhile, the water reservoir bottom surface 3261 may be inclined downward along a direction in which the installation partition wall 3211 protrudes from the inner surface of the duct body 321 . That is, in the drawing, the installation partition wall 3211 protrudes to the left. In this case, the bottom surface 3261 of the water reservoir may be inclined downward to the left.

When the installation partition wall 3211 is provided, residual water may be generated between the rear of the installation partition wall 3211 and the inner wall of the duct body 321 . When the slope of the installation partition wall 3211 is formed as described above, there is an effect of preventing residual water from being generated by the installation partition wall 3211.

Meanwhile, the water storage unit 326 may include a drain pipe 3263 passing through one side of the circulation duct 320 and communicating the water storage unit 326 and the outside of the circulation duct. The drain pipe 3263 may be provided to pass through the duct body 321 . A drain pipe may be provided to pass through the front surface of the water reservoir 326 .

Meanwhile, the installation bulkhead 3211 may be disposed on one side of the water reservoir 326 in the width direction, and the drain pipe may be disposed on the other side of the water reservoir 326 in the width direction. In other words, the installation bulkhead 3211 and the drain pipe 3263 may be disposed in different directions based on the width direction of the water reservoir 326 .

For example, when the installation partition wall 3211 is disposed on the right side of the water reservoir 326, the drain pipe 3263 may be disposed on the left side of the water reservoir 326.

As described above, when the water reservoir bottom surface 3261 is inclined downward along the protruding direction of the installation partition wall 3211, water inside the water reservoir 326 may be collected in the protruding direction. At this time, in order to more effectively discharge the water inside the water reservoir 326 from the drain pipe 3263, the drain pipe 3263 should be located in a direction in which water is collected.

Therefore, as described above, when the installation partition wall 3211 and the drain pipe 3263 are located in opposite directions based on the inclination, it is possible to prevent residual water from being generated by the installation partition wall 3211. At the same time, there is an effect of discharging the water inside the water reservoir 326 more effectively.

Meanwhile, the bottom surface 3261 of the water reservoir may be inclined downward toward the drain pipe 3263. The drain pipe 3263 is a component for discharging water inside the water storage part 326 to the outside of the water storage part 326 . Accordingly, when the water inside the water storage part 326 is concentrated toward the drain pipe 3263, the water inside the water storage part 326 can be removed more effectively.

Accordingly, when the slope of the bottom surface 3261 of the water reservoir is inclined downward toward the drain pipe 3263, the water inside the water reservoir 326 may be concentrated toward the drain pipe 3263. That is, the water inside the water reservoir 326 can be easily discharged, and the occurrence of residual water can be effectively prevented.

For example, when the drain pipe 3263 is formed on the left side of the front of the water reservoir 326, the bottom surface 3261 of the water reservoir may be inclined downward toward the front. At the same time, the water reservoir bottom surface 3261 may be inclined downward toward the left side.

Meanwhile, the water storage part 326 may include a water storage part recessed part 3262 positioned lower than the water storage part bottom surface 3261 in which one side of the water storage part bottom surface 3261 is depressed.

The water storage depression 3262 may be positioned closest to the ground among the water storage parts 326 . The water reservoir depression 3262 may be located in a direction in which the water reservoir bottom surface 3261 is inclined downward. For example, when the water reservoir bottom surface 3261 is inclined downward toward the left front side, the water reservoir depression 3262 may be formed on the left front side of the water reservoir bottom surface 3261 .

In addition, the drain pipe 3263 may be provided to communicate the outside of the circulation duct 320 with the water storage depression 3262 . That is, the drain pipe 3263 is formed where the water inside the water reservoir 326 is gathered, so that the water inside the water reservoir 326 can be discharged more effectively.

The drain pipe 3263 may be formed to pass through one side of the circulation duct 320 where the water storage depression 3262 is located. That is, the drain pipe 3263 may be provided so that the lowermost portion of the water reservoir 326 communicates with the outside.

Meanwhile, referring to FIG. 23 , the water reservoir 326 may include a water level sensor 3266 that senses the level of water collected in the water reservoir 326 . In addition, the water level sensor 326 is provided to pass through one side of the circulation duct 320 and may include a sensor insertion hole 3267 into which a part of the water level sensor 3266 is inserted. In particular, the sensor insertion hole 3267 may be formed to pass through the side of the circulation duct 320 .

The sensor insertion hole 3267 may be located above the maximum height of water collected in the water reservoir. In other words, the sensor insertion hole height HL, which is the height between the water reservoir bottom surface 3261 and the sensor insertion hole 3267, may be longer than the maximum water level WL.
