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.

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

Referring to FIG. 21 (a), the outside air damper 373 shields the outside air suction unit 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. 21 (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.

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 .

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. 21(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.

22 shows the installation structure of the steam supply unit.

The steam supply unit 800 may be supported by being seated on the base cover 360 .

The fastening part 3631 may be provided with a structure that is detachably coupled to a protruding part protruding from the lower part of the steam case 810.

Thus, even if a large amount of water is contained in the steam case 810, the steam case 810 can be stably seated on the base cover 360.

In addition, since the steam case 810 is disposed above the circulation duct 320 and the distance to the inner case 200 is shorter, the steam generated in the steam case 810 flows into the inner case 200. Condensation before reaching can be minimized.

23 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. 23 , 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. . Thus, there is an effect that productivity of the laundry treatment apparatus can be improved.

Meanwhile, the circulation duct 320 may include a duct body 321 extending from the base part 310 toward the inner case 200 . The duct body 321 may extend upward from the base portion 310 . The duct body 321 may form a flow path through which air in the laundry treatment space 220 circulates.

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.

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

Referring to FIG. 24 , 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 .

25 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. 25 shows a cross section of a portion of the circulation duct cut in a plane parallel to the ground.

Meanwhile, the base unit 310 may include a control unit installation unit 313 formed below the circulation duct 320 to provide a space in which the control unit 700 is installed. The bottom surface 325 of the circulation duct may form an upper surface of the controller installation part 313 . At least a part of the controller installation part 313 may be disposed below the bottom surface 325 of the circulation duct.

In addition, the water reservoir side surface 3265 forming the side surface of the water reservoir 326 may form one side surface of the control unit 700 . 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. 25 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. 25, 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 removed more easily, and the effect of reducing defects of 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.

26 is a view of a circulation duct and a base unit according to an embodiment of the present invention from the side of the compressor installation unit. In particular, FIG. 26 illustrates a compressor installation unit according to an embodiment of the present invention.

Referring to FIG. 26 , the laundry treatment apparatus according to an embodiment of the present invention includes an evaporator 341 and a condenser 343 installed, a circulation duct 320 providing a passage through which air in the laundry treatment space circulates, and the above A base part 310 including a compressor installation part 312 disposed under the circulation duct 320 and providing a space in which the compressor 342 is installed may be included. The compressor installation part 312 may be integrally formed with the bottom part 311 of the base. The compressor installation part 312 may be integrally formed with the base bottom part 311 when the base part is manufactured.

In a conventional laundry treatment apparatus, a compressor installation part is separately coupled to a base forming a bottom surface. However, when the compressor installation part 312 is integrally formed with the base part 310 as in the present invention, vibration generated from the compressor 342 can be more effectively reduced. In addition, since the compressor 342 is configured to generate a lot of vibration, there is an effect of securing the stability of the compressor 342.

The compressor installation part 312 may be located below the bottom surface 325 of the circulation duct. In other words, the compressor installation part 312 may be formed by being recessed in the base bottom part 311 . That is, the compressor installation part 312 may be located closer to the ground than the bottom surface 325 of the circulation duct. Also, the compressor installation part 312 may be farther from the inner case than the bottom surface 325 of the circulation duct.

In general, the compressor 342 is one of components that generate a lot of vibration or noise. At this time, as described above, when the compressor installation part 312 is provided at a low position, there is an effect of securing structural stability against vibrations generated from the compressor 342 .

The compressor installation part 312 may include an installation protrusion 3121 protruding from the base bottom part 311 . The installation protrusion 3121 may be coupled to the compressor 342 .

In addition, the compressor installation part 312 may include a circumferential rib 3123 protruding upward from the base bottom part 311, having a cylindrical shape, and located below the compressor. In addition, the compressor installation part 312 may include a radial rib 3124 protruding upward from the base bottom part 311 and extending in a radial direction from the circumferential rib 3123 .

The circumferential rib 3123 and the radial rib 3124 are disposed under the compressor 342 to reduce vibration or noise generated from the compressor 342 . In addition, the circumferential rib 3123 and the radial rib 3124 may be disposed between the plurality of installation protrusions 3121 . In addition, the circumferential rib 3123 and the radial rib 3124 may be arranged to connect the plurality of installation protrusions 3121 to each other.

The circumferential rib 3123 and the radial rib 3124 may improve structural stability of the compressor installation part 312 . In addition, the circumferential rib 3123 and the radial rib 3124 may support the lower side of the compressor 342 or form an installation surface 3122 disposed under the compressor 342 .

Meanwhile, the compressor installation part 312 may be integrally formed with the base bottom part 311. In this case, the compressor installation part 312 may be molded through a mold. A mold forming the compressor installation part 312 may be removed in the height direction of the cabinet 100 . The drawing shows a direction MR for removing the mold forming the compressor installation part.

In addition, the base part 310 may include a control unit installation part 313 providing a space in which the control unit 700 is installed. The compressor installation unit 312 may be disposed to overlap at least a portion of the control unit installation unit 313 in the width direction of the base unit.

As described above, both the control unit installation unit 313 and the compressor installation unit 312 may be formed by the base unit 310, and are disposed in the width direction, thereby improving space utilization.

In addition, the base part 310 may include a reinforcing partition wall 3125 extending upward from the base bottom part 311 and disposed between the circulation duct 320 and the compressor installation part 312 . The reinforcing partition wall 3125 may form one surface of the compressor installation part 312 .

The reinforcing partition wall 3125 may extend by a predetermined height. The reinforcing bulkhead 3125 may extend higher than the compressor installation part 312 . The reinforcing bulkhead 3125 may be formed by a mold forming the compressor installation part 312 .

The reinforcing bulkhead 3125 may increase the mass around the compressor installation part 312 . As the mass around the compressor installation part 312 increases, vibration generated from the compressor 342 can be more effectively reduced.

In addition, the reinforcing bulkhead 3125 may be disposed in front of the compressor installation part 312 . Therefore, the reinforcing bulkhead 3125 has an effect of reducing a certain portion of the noise emitted from the compressor 342 .

Meanwhile, the reinforcing partition wall 3125 may have a reinforcing partition wall surface 3125s on one side facing the compressor 342 . The reinforcing partition wall surface 3125s may form a predetermined angle with the mold removal direction MR. That is, the reinforcing bulkhead 3125s forms a predetermined angle with the height direction so that the mold can be removed more easily.

In addition, the base part 310 extends upward from the base bottom part 311 and may include a support partition wall 3126 forming the other surface of the compressor installation part 312 .

The support partition wall 3126 may be disposed to be spaced apart from the reinforcing partition wall 3125 . When the reinforcing bulkhead 3125 is disposed in front of the compressor 342 , the support bulkhead 3126 may be disposed in the rear of the compressor 342 .

The support partition wall 3126 may also extend by a predetermined height like the reinforcing partition wall 3125 . That is, the support bulkhead 3126 may also increase the mass around the compressor installation part 312 to reduce vibration generated from the compressor 342 . Also, the support partition wall 3126 may reduce noise emitted from the compressor 342 .

The support bulkhead 3126 may also be formed through a mold formed by the compressor installation part 312 .

In addition, the base part 310 may further include a connection partition wall 3127 connecting the reinforcing partition wall 3125 and the support partition wall 3126 to each other. The connection partition wall 3127 may extend upward from the bottom part 311 of the base. The connection partition wall 3127 may form one surface of the compressor installation part 312 .

The connection partition wall 3127 extends upward from the base bottom part 311 to separate the compressor installation part 312 and the controller installation part 313 from each other. That is, the connection partition wall 3127 separates a space where the compressor 342 is installed and a space where the control unit 700 is installed to prevent electrical signals between the compressor 342 and the control unit 700 from being interfered with.

Meanwhile, the base part 310 may include a handle part 3128 formed behind the compressor installation part 312 and the supporting bulkhead 3126 . The handle part 3128 may be formed in a shape that is easy for a worker to grip.

A worker may hold the handle part 3128 when moving the base molding M in which the base part 310 and the circulation duct 320 are integrally formed. The handle part 3128 has an effect of improving productivity of workers.

In addition, the handle part 3128 may be integrally formed with the base part 310 . That is, the handle part 3128 may be formed by a mold forming the base part 310 . In addition, the handle portion 3128 may be overlapped with the compressor installation portion 312 in the front-back direction. The handle portion 3128 can reduce vibration generated by the compressor 342 by enhancing the mass near the compressor installation.

27 shows a top view of the base part and a cross-sectional view of the compressor installation part of the present invention. In particular, FIG. 27 shows a cross section of a reinforcing bulkhead.

Referring to the drawing showing the base portion 310 from above, the compressor installation portion 312 may be disposed to overlap at least a portion of the circulation duct 320 in the front-back direction. In addition, the compressor installation unit 312 may be disposed to overlap at least a portion of the circulation duct 320 and the base unit 310 in the width direction.

As described above, when the compressor installation unit 312 is overlapped with the circulation duct 320 in the front-rear or width direction, it is possible to utilize the limited space more efficiently.

In addition, the compressor installation unit 312 may be disposed to overlap at least a portion of the water storage unit 326 in the front-back direction. The water reservoir 326 is configured to collect condensed water and may be disposed closer to the ground. When the compressor installation part 312 overlaps the water storage part 326 in the front-rear direction, the compressor installation part 312 may also be disposed close to the ground. Therefore, vibration generated by the compressor 342 can be effectively reduced to ensure structural stability.

Meanwhile, the reinforcing bulkhead 3125 may be inclined so as to be closer to the circulation duct 320 as it extends from the base bottom part 311 . More specifically, the reinforcing partition wall surface 3125s may be inclined so as to be closer to the circulation duct 320 as it extends from the base bottom part 311 . In other words, the reinforcing bulkhead 3125s may be inclined so as to be closer to the circulation duct 320 as it extends upward.

Referring to FIG. 27 , a cross section of the reinforcing bulkhead 3125 taken along A-A' and a cross section taken along B-B' are shown.

The reinforcing bulkhead 3125 may be inclined in a direction away from the compressor 342 as it extends upward from the base bottom portion 311 . In other words, the reinforcing bulkhead 3125s may form a predetermined angle with the mold removal direction MR.

In particular, the reinforcing bulkhead 3125s may be inclined in a direction away from the compressor 342 based on the mold removal direction MR or in a direction closer to the circulation duct 320 based on the mold removal direction MR. .

There is an effect that the mold forming the reinforcing partition 3125 can be more easily removed by the inclination.

In addition, the installation protrusion 3121, the circumferential rib 3123, and the radial rib 3124 may also be formed such that their cross-sectional area decreases toward the upper side. Accordingly, the mold forming the installation protrusion 3121, the circumferential rib 3123, the radial rib 3124, and the like can be easily removed.

28 is a side view of the circulation duct and the base unit according to an embodiment of the present invention from the side of the compressor installation unit.

The reinforcing bulkhead height 3125L, which is the length of the cabinet 100 in the height direction of the reinforcing bulkhead 3125, is smaller than 1/2 of the circulation duct height ML, which is the length of the cabinet 100 in the height direction of the circulation duct, and the circulation duct height ( ML) may be provided larger than 1/3.

Here, the circulation duct height ML may mean the vertical distance between the uppermost and lowermost ends of the circulation duct. In addition, the circulation duct height (ML) may mean the height of the base molding (M) including both the circulation duct 320 and the base portion 310. That is, the circulation duct height (ML) may mean the distance between the top end and the bottom end of the base molding (M).

When the height of the reinforcing bulkhead 3125L is provided as described above, the reinforcing bulkhead 3125 can reduce vibration and reduce noise of the compressor. In addition, it is possible to prevent interference with components disposed above the reinforcing bulkhead 3125. It can be prevented. That is, when the reinforcing bulkhead 3125 is formed as described above, the space inside the machine room can be utilized more effectively.

Meanwhile, the support partition wall height 3126L, which is the length of the support partition wall 3126 in the height direction of the cabinet 100, may be smaller than the reinforcing partition wall height 3125L. Since the support bulkhead 3126 is disposed behind the compressor 342, it may have less effect on noise reduction than the reinforced bulkhead 3125.

In addition, a fan installation unit may be provided on a side surface of the support partition wall 3126 . Accordingly, when the height of the support partition wall 3126L is smaller than the height of the reinforcing partition wall 3125L, it is possible to prevent the support partition wall 3126 from interfering with the fan installation unit 350. Therefore, there is an effect of efficiently utilizing a limited space.

Meanwhile, the reinforcing bulkhead 3125 and the supporting bulkhead 3126 may be disposed to overlap each other along the front-back direction. In addition, the reinforcing bulkhead 3125 may be disposed in front of the supporting bulkhead 3126 .

In addition, a handle portion 3128 may be disposed behind the support partition wall 3126 . That is, the reinforcing partition wall 3125, the support partition wall 3126, and the handle part 3128 may be sequentially arranged along the front-back direction. In addition, the reinforcing bulkhead 3125 , the supporting bulkhead 3126 , and the handle part 3128 may be disposed to surround the compressor installation part 312 . That is, the reinforcing partition wall 3125 , the support partition wall 3126 , and the handle part 3128 may form one surface of the compressor installation part 312 .

In addition, when the base part 310 is formed, the reinforcing partition wall 3125, the support partition wall 3126, and the handle part 3128 may be formed as a single injection molding material using a mold. That is, the base bottom part 311, the reinforcing partition wall 3125, the support partition wall 3126, and the handle part 3128 may all be integrally formed.

Meanwhile, the connection partition wall 3127 may be inclined downwardly from the reinforcing partition wall 3125 toward the support partition wall 3126. Since the connection partition wall 3127 is formed to be inclined downward toward the rear, it is possible to prevent the connection partition wall 3127 from interfering with the fan installation part 350 .

In addition, the connection partition wall 3127 may be formed to have a reduced inclination angle as it extends from the reinforcing partition wall 3125 to the support partition wall 3126.

In particular, the control unit installation unit 313 may be disposed below the circulation duct 320. That is, the controller 700 may be installed in the controller installation unit 313 and disposed below the circulation duct 320 . More specifically, the controller 700 may be installed in the controller installation unit 313 and disposed below the duct body 321 .

As described above, the base portion 310 and the circulation duct 320 may be integrally formed. As described above, the base portion 310 and the circulation duct 320 may be integrally injection molded using a mold.

In addition, the controller installation unit 313 may be disposed to overlap at least a portion of the circulation duct 320 in the height direction of the cabinet 100 . That is, the controller installation unit 313 and the circulation duct 320 may be arranged in a vertical direction.

When the controller installation unit 313 and the circulation duct 320 are disposed vertically, the space inside the machine room can be utilized more efficiently. In addition, the controller installation unit 313 may be formed indirectly as the circulation duct 320 is formed. That is, it is understood that the control unit installation unit 313 is naturally formed in the process of integrally forming the base unit 310 and the circulation duct 320 without adding a separate part to form the control unit installation unit 313. It can be.

Therefore, when provided as described above, the process of adding a separate bracket to install the control unit can be reduced like in the conventional laundry treatment apparatus. That is, there is an effect of improving the assemblability of the entire laundry treatment apparatus.

Meanwhile, the controller installation unit 313 may be formed by recessing a part of the circulation duct 320 . In particular, the control unit installation unit 313 may be formed as the rear side of the circulation duct 320 is depressed toward the front side. That is, the control unit installation unit 313 may be formed between the base bottom unit 311 and the circulation duct 320.

Meanwhile, the controller 700 may include a bracket 3131 surrounding an outer surface of the controller 700 . The bracket 3131 may be formed of a metal material.

The control unit may include a control unit seating protrusion 3136 protruding from the front surface of the control unit. The control seating protrusion 3136 may be coupled to the guide 3133. That is, the control unit seating protrusion 3136 is combined with the guide 3133 to determine the location of the control unit 700 within the control unit installation unit 313 .

In addition, the control unit 700 may include a control unit fixing protrusion 3137 protruding from the rear surface of the control unit.

That is, the movement of the control unit 700 in the forward and backward directions can be limited by the control unit seating protrusion 3136 and the control unit fixing protrusion 3137. A specific coupling structure of the control unit fixing protrusion 3137 will be described later.

The description of the structure and shape of the above-described control unit seating protrusion 3136 and the control unit fixing protrusion 3137 merely describes one embodiment. That is, whether the control unit seating protrusion 3136 and the control unit fixing protrusion 3137 protrude or sink can be appropriately changed.

In addition, the controller 700 may include a supporter 3132 protruding from the side of the controller 700 . The supporter 3132 may extend forward and backward. In addition, the control unit installation unit may further include a control unit rib 3134 protruding from the inner sidewall of the control unit installation unit 313 .

The control rib 3134 may extend forward and backward. The supporter 3132 may be positioned above the control rib 3134. That is, the control rib 3134 may support the supporter 3132 from the lower side.

Meanwhile, the inner wall of the controller installation unit 313 may form one surface with the connection partition wall 3127 . In addition, the supporter 3132 may protrude from the inner surface of the controller installation part 313 forming one surface with the connection partition wall 3127.

Meanwhile, as shown in FIG. 29 , the control unit installation unit 313 may be integrally formed with the base bottom unit 311 and the circulation duct 320 using a mold. In particular, the mold forming the controller installation part 313 can be removed backward. 29 shows a mold removal direction MR, which is a drawing direction of a mold forming the controller installation part 313.

When the control unit 700 is installed in the control unit installation unit 313, the control unit 700 may be inserted into the control unit installation unit 313 in a direction opposite to the mold removal direction MR.

The laundry treatment apparatus according to an embodiment of the present invention may further include a noise filter 390 for removing noise from electrical signals transmitted to and received from the controller 700 . The noise filter 390 may be provided to remove noise from electrical signals transmitted and received not only to the control unit 700 but also to the compressor 342 and the fan installation unit 350.

The noise filter 390 may be disposed adjacent to the controller 700. When the noise filter 390 and the control unit 700 are disposed close to each other, electrical connection may be facilitated. The noise filter 390 may be disposed behind the controller 700. In particular, it may be disposed adjacent to the control unit 700 in the forward and backward directions. Also, the noise filter 390 may be coupled to the base part 310 .

The base part 310 may include a noise filter installation part 3138 protruding from the base bottom part 311 . The noise filter installation unit 3138 may be disposed behind the control unit installation unit 313 . The noise filter installation unit 3138 may also be formed by a mold forming the control unit installation unit 313 .

At this time, in order to form the noise filter installation part 3138 protruding from the base bottom part 311, the controller installation part 313 may include a noise filter guide 3139 to help remove the mold. The noise filter guide 3139 protrudes from the base bottom part 311 and may extend along the front and rear directions. The noise filter guide 3139 may be overlapped with the noise filter installation part 3138 in the front-back direction.

The noise filter guide 3139 may extend along the mold removal direction MR, and in particular, may have a reduced cross-sectional area along the mold removal direction MR. That is, the noise filter guide 3139 may be provided such that its sectional area increases as the distance from the noise filter installation part 3138 increases. When the cross-sectional area change of the noise filter guide 3139 is provided as described above, there is an effect that the mold forming the noise filter installation part 3138 can be more easily removed.

30 is a view from the rear side of the controller installation unit of the present invention.

Referring to FIG. 30 , it can be seen that the front circumference of the control unit installation part 313 is smaller than the rear circumference of the control unit installation unit 313 . Here, the circumference of the controller installation unit 313 may mean the circumference of the cross section of the control unit installation unit 313 perpendicular to the mold removal direction MR of FIG. 29 . In other words, it may mean the circumference of the cross section of the control unit installation part 313 perpendicular to the front-back direction.

36 shows a state in which the control unit and the fan installation unit are coupled to the circulation duct and the base unit according to an embodiment of the present invention from the rear.

Referring to FIG. 36 , in a state where the fan installation unit 350 is installed in the circulation duct 320, the fan installation unit 350 may overlap at least a portion of the control unit 700 in the front-back direction. Also, as described above, in the process of installing the fan installation unit 350 to the circulation duct 320, the fan installation unit 350 and the control unit 700 may be coupled to each other. Through this, the location of the control unit 700 may be determined.

When the protective rib 3553 is disposed to overlap the noise filter 390 in the height direction, the protective rib 3553 can more effectively prevent moisture from falling onto the noise filter 390 .

Also, the noise filter 390 may be disposed to overlap the inclined surface 3553a in the height direction. Water falling on the inclined surface 3553a may move in a direction avoiding the noise filter 390 due to the inclined surface 3553a.

Meanwhile, the blowing fan 353 may be disposed to overlap the condenser 343 and the evaporator 341 in the front-back direction. In a conventional laundry treatment apparatus, an evaporator and a condenser are spaced apart from a blowing fan in a height direction. Accordingly, flow loss could occur.

However, in the laundry treatment apparatus according to an embodiment of the present invention, the condenser 343 or the evaporator 341 is arranged to overlap the blowing fan 353 in the front-back direction, thereby preventing flow loss from occurring. In addition, the blowing fan 353 is disposed at the rear of the evaporator 341 or the condenser 343 so that airflow supplied to the laundry treatment space 220 can be more easily controlled.

Also, the fan housing 351 may overlap the compressor 342 and the base part 310 in a width direction. In other words, the fan housing 351 may overlap the compressor 342 in the left and right directions. By disposing the fan housing 351 at the rear, it can overlap with the compressor 342 in the width direction, and space utilization can be increased.

Also, the fan housing 351 may be disposed to overlap at least a portion of the steam supply unit 800 and the base unit in the width direction. In the conventional laundry treatment apparatus, since the fan housing is disposed at the front side of the machine room, it is difficult to overlap the steam supply unit in the width direction. However, in the present invention, as the fan housing 351 is installed at the rear of the circulation duct 320, the fan housing 351 may overlap the steam supply unit 800 in the width direction.

The steam supply unit 800 and the fan housing 351 generate hot air or steam supplied to the laundry treatment space 220 . That is, when the components for generating hot air or steam supplied to the laundry treatment space 220 are arranged to overlap in the width direction, they can be easily connected to through-holes disposed at the rear of the bottom surface of the laundry treatment space. Therefore, there is an effect of improving the efficiency of space utilization.

That is, manufacturing convenience and assembly can be improved.

37 is a cross-sectional view of a circulation duct, a base part, and a fan installation part according to an embodiment of the present invention. In particular, it shows a cross section perpendicular to the width direction of the base portion.

Accordingly, an air discharge pipe parting line 3236 may be formed at a point where the air discharge pipe 3232 and the air extension pipe 3231 are connected. 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. For example, the mold forming the air extension pipe 3231 can be removed forward. At this time, the inner diameter of the air extension tube 3231 may increase as it goes forward.

On the other hand, the mold forming the air discharge pipe 3232 may be removed backward. At this time, the inner diameter of the air discharge pipe 3232 may increase toward the rear.

When formed as described above, the inner diameter of the portion where the air extension pipe 3231 and the air discharge pipe 3232 are connected may be formed to be the smallest in the entire air discharge portion 323. That is, the inner diameter of the portion where the air extension pipe 3231 and the air discharge pipe 3232 are connected may be formed to be the smallest among the air extension pipe 3231 and the air discharge pipe 3232. In other words, the air discharge pipe parting line 3236 The diameter of may be formed to be the smallest among the inner diameters of the air discharge unit 323.

In other words, the internal cross-sectional area of the air extension pipe 3231 decreases along the extension direction of the air extension pipe 3231, and the internal cross-sectional area of the air discharge pipe 3232 increases along the extension direction of the air discharge pipe 3232. can Here, the extension direction may mean rear. Also, the extension direction may refer to an extension direction of the air discharge unit 323 .

Also, the first housing 354 may communicate with the air discharge pipe 3232. The fan housing inlet 3542 may be coupled in communication with the air discharge pipe 3232. That is, when the duct coupling portion 3543 and the discharge coupling portion 3234 are coupled, the fan housing inlet portion 3542 and the air discharge pipe 3232 may be placed in communication with each other.

38 is a top view of a cross section of a circulation duct according to an embodiment of the present invention. In particular, it shows a state in which the circulation duct is cut into a cross section parallel to the ground.

Referring to FIG. 38, the inner diameter D1 of the air extension pipe decreases along the extension direction of the air extension pipe, and the degree of decrease of the inner diameter D1 of the air extension pipe decreases along the extension direction of the air extension pipe. It can be. That is, the inner diameter D1 of the air extension pipe may decrease as the distance from the duct body 321 increases, and the decrease rate may decrease as the distance increases from the duct body 321 .

In other words, the inner diameter D1 of the air extension pipe may decrease more rapidly as it is closer to the duct body, and may decrease more gently as it is farther from the duct body.

When the inner diameter D1 of the air extension pipe is formed according to the aforementioned reduction rate, the inside of the air extension pipe may be provided in a bell mouth shape. The flow rate of air passing through the air extension pipe 3231 can be improved by the above shape. In addition, there is an effect of reducing the flow loss of the air flowing through the air extension pipe 3231.

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. They may be provided differently.

Here, the extension direction of the air extension pipe 3231 and the extension direction of the air discharge pipe 3232 may mean forward and backward directions. Also, the extension direction of the air extension pipe 3231 and the extension direction of the air discharge pipe 3232 may refer to directions in which the evaporator 341 and the condenser 343 are sequentially arranged.

Referring to the enlarged view of FIG. 38, the gradient 3231r formed between the inner surface of the air extension pipe 3231 and the extension direction of the air extension pipe 3231 is such that the inner surface of the air discharge pipe 3232 extends 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. 38 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 .

Meanwhile, the air discharge unit 323 may be disposed to overlap at least a portion of the compressor 342 and the base unit 310 in the width direction. 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.

When arranged as described above, the limited space of the machine room can be utilized more efficiently. Accordingly, there is an effect of further securing the laundry treatment space 220 .

39 illustrates a state in which the steam supply unit of the laundry treatment apparatus according to an embodiment of the present invention is coupled from the rear. In particular, it shows a state in which the disassembled components of FIG. 22 are combined.

Referring to FIG. 39 together with FIG. 4 , the steam supply unit 800 may be disposed to overlap at least a portion of the compressor 342 in the height direction of the cabinet 100 .

In a conventional laundry treatment apparatus, a steam supply unit overlaps a compressor in a width direction. In a conventional laundry treatment apparatus, since the circulation duct and the base are spaced apart from each other, it is difficult for the compressor and the steam supply unit to overlap in the height direction.

However, in the laundry treatment apparatus according to an embodiment of the present invention, the base part 310 and the circulation duct 320 are integrally formed, and the area occupied by the compressor on the base part 310 is reduced. Accordingly, the arrangement structure of the steam supply unit 800 is also changed.

As the above-described arrangement structure is changed, the steam supply unit 800 may be disposed above the compressor installation unit 312 . In other words, the steam supply unit 800 may be disposed above the compressor 342 . A specific arrangement structure of the steam supply unit 800 will be described later.

It may include a fan installation unit 350 for circulation.

The steam supply unit 800 may be disposed to overlap at least a portion of the fan installation unit 350 and the base unit 310 in a width direction. As the steam supply unit 800 is installed on the base cover 360, the steam supply unit 800 may overlap with the fan installation unit 350 in the width direction.

In addition, the fan installation part 350 is coupled to a blowing fan 353 that forms an airflow in which air in the laundry treatment space 220 circulates and is coupled to the circulation duct 320 to accommodate the blowing fan 353. A fan housing 351 and a discharge duct 352 extending from the fan housing 351 toward the inner case 200 and communicating the fan housing 351 and the inner case 200 may be included.

That is, the discharge duct 352 may be formed to extend upward from the fan housing 351 . That is, the discharge duct 352 may be located closer to the inner case 200 than the blowing fan 353 .

The steam supply unit 800 may be disposed to overlap at least a portion of the discharge duct 352 in a width direction of the base unit.

As the steam supply unit 800 is disposed on the base cover 360, it may be disposed to overlap the discharge duct 352 in the width direction.

In a conventional laundry treatment apparatus, the steam supply unit 800 is disposed below the circulation duct 320. Accordingly, the steam supply unit 800 is located farther from the inner case 200 than the circulation duct 320 . However, the steam supply unit 800 according to the present invention may be disposed above the circulation duct 320. Accordingly, it may be disposed to overlap with the discharge duct 352 in the width direction.

Both the discharge duct 352 and the steam supply unit 800 may communicate with the laundry treatment space 220 and supply hot air or moisture to the laundry treatment space 220 . Therefore, it is preferable to arrange the discharge duct 352 and the steam supply unit 800 adjacent to the laundry treatment space 220 in consideration of thermal efficiency and the like.

Therefore, as the steam supply unit 800 overlaps the discharge duct 352 in the width direction, the steam generated in the steam supply unit 800 is prevented from decreasing in temperature while moving to the laundry treatment space 220. can do.

The installation bracket 870 may perform a function of protecting the steam case 810. The compressor 342 is provided to discharge high-temperature and high-pressure refrigerant. Therefore, the possibility of ignition may be high. However, since the steam supply unit 800 also generates steam inside, it is maintained at a high temperature, and thus the possibility of ignition may be high.

At this time, the installation bracket 870 is arranged to surround one surface facing the compressor 342 of the steam case 810 can prevent the steam case 810 from being ignited by the compressor 342.

As described above, in order to prevent the ignition of the installation bracket 870 of the steam case 810, the installation bracket 870 may be provided with an incombustible material. In particular, the installation bracket 870 may be made of a metal material. The installation bracket 870 also performs a function of preventing ignition of the steam case 810, but may also perform a position fixing role of the steam case 810. Therefore, when the installation bracket 870 is made of a metal material, the steam case 810 can be supported more firmly.

In addition, a steam support part 812 extending along the circumference of the steam body 811 may be included. The steam support part 812 protrudes from the steam body and may extend along the circumference of the steam body 811 .

The aforementioned fixing clip 873 may be coupled to the steam support 812 . The fixing clip 873 is provided in a shape corresponding to the steam support part 812 and can be more firmly fixed with the steam case 810.

The bracket recessed portion 875 may be formed by recessing a portion of the lower panel 871 downward. In addition, the bracket recessed portion 875 may be formed by pressing the lower panel 871 . A portion of the lower panel 871 and the steam case 810 may be spaced apart from each other by the bracket depression 875 .

In addition, an air layer may be formed in the bracket depression 875 . Accordingly, it is possible to more effectively prevent a fire in the compressor 342 or heat generated in the compressor 342 from being transferred to the steam case 810 . That is, the recessed bracket 875 has an effect of preventing fire in the steam supply unit 800 .

Meanwhile, the laundry treatment apparatus according to an embodiment of the present invention may include a base cover 360 coupled to the circulation duct 320 to shield at least a portion of an open upper surface of the circulation duct 320. . In addition, the base cover 360 may form a part of a passage through which air in the laundry treatment space 220 circulates. In particular, the base cover 360 may form an upper side surface of a passage through which air in the laundry treatment space 220 circulates.

The steam fixing part 3632 may be coupled to the installation bracket 870. The steam fixing part 3632 may extend in a direction away from the inflow body 361 from the shielding body 363 .

In addition, the installation bracket 870 may include a bracket fixing part 874 extending downward from the lower panel 871 . The bracket fixing part 874 may extend from the lower panel 871 in a direction away from the steam case 810 . The bracket fixing part 874 may be formed by bending one side of the lower panel 871 .

The bracket fixing part 874 may be combined with the steam fixing part 3632. The bracket fixing part 874 may be coupled to the steam fixing part 3632 through a separate fastening member. That is, the steam supply unit 800 may be disposed above the compressor 342 by combining the bracket fixing unit 874 and the steam fixing unit 3632.

Meanwhile, the installation bracket 870 may include a bracket hole 876 formed through the lower panel 871 . The bracket hole 876 may be formed to pass through one side of the lower panel 871 facing the steam case 810 .

In addition, the steam case 810 may include a steam protrusion 813 that protrudes from the steam body 811 and is inserted into the bracket hole 876.

The steam protrusion 813 is inserted into the bracket hole 876 so that the steam case 810 and the installation bracket 870 can be firmly fixed.

The steam protrusion 813 and the bracket hole 876 may be provided in plurality. When the plurality of steam protrusions 813 and the bracket hole 876 are coupled, the relative movement of the steam case 810 on the installation bracket 870 can be prevented.

41 is a cross-sectional view of a steam supply unit according to an embodiment of the present invention;

Referring to FIG. 41 , a portion of the lower panel 871 may be spaced apart from the steam case 810 by the bracket depression 875 . In addition, the fixing clip 873 may be supported by the steam support part 812 . The fixing clip 873 may be coupled with the steam support 812 .

The fixing clip 873 may be made of a material that is elastically deformed. Therefore, the fixing clip 873 can be removed from the steam case 810 by elastically deforming the fixing clip 873 in a direction away from the steam case 810 .

42 is an exploded perspective view of a steam supply unit according to an embodiment of the present invention from a lower side.

Referring to FIG. 42 , it can be seen in more detail that the steam protrusions 813 protrude from the lower surface of the steam body 811 . In addition, the steam case 810 may include a steam rib 814 that is spaced apart from the steam protrusion 813 and protrudes from the lower surface of the steam body 811 .

Meanwhile, the installation bracket 870 may include a bracket slit 877 penetrating one side of the lower panel 871 . The bracket slit 877 may be formed to be spaced apart from the bracket hole 876 .

The steam rib 814 may be inserted into the bracket slit 877. The steam rib 814 may extend in the same direction as the bracket slit 877. The steam rib 814 may prevent movement in a direction perpendicular to the extension direction.

As described above, the steam protrusion 813 and the steam rib 814 are spaced apart from each other to support the steam case 810 at different points. Therefore, the steam rib 814 and the steam protrusion 813 can increase the bonding force between the steam case 810 and the installation bracket 870. Accordingly, the steam ribs 814 and the steam protrusions 813 have an effect of improving structural stability of the entire steam supply unit 800 .

43 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 number 43, the laundry treatment apparatus according to an embodiment of the present invention is provided inside the 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 water 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 bottom surface 325 of the circulation duct from the inner case 200 . 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 .
