Description

Clothes dryer

The present invention relates to a clothes dryer for drying clothes.

The conventional clothes dryer is provided with a lint filter called lint filter for collecting lint generated from clothes (see, for example, Patent Literature 1 and Patent Literature 2).

A conventional clothes dryer comprises a drying drum having at least an inlet for containing clothes, and a door. The drying drum is configured in a bottomed cylindrical shape having an inlet on the front side and a bottom on the rear side. The drying drum rotates about an axis of rotation provided horizontally. And a user can carry in and out clothes from a drying drum by opening and closing a door.

Further, a blower fan is provided on the back side of the drying drum, and the drying air is blown from the back side to the front side of the drying drum by the rotation of the blower fan. The drying air blown into the drying drum passes through the door through a circulation passage provided below the drying drum, and reaches the blower fan again. As described above, drying air circulates to dry the garment.

At this time, the circulating drying air contains lint generated from the clothes. Then, the lint may reach the blower fan or the heating unit to cause a problem. Then, in order to control a malfunction, a lint filter is provided in a door and lint is collected.

When cleaning the lint filter, the user opens the door and removes the lint filter from the door. Then, the foreign substance such as lint collected by the lint filter is discarded.

However, in the conventional clothes dryer, the lint filter is provided detachably from the door. At this time, if the lint filter is not reliably accommodated in the door, a gap may be generated between the lint filter and the door, and the circulating drying air may leak from the circulation passage. As a result, there has been a problem that the air blowing amount of the drying air circulating in the circulation passage is reduced, and the drying performance of the clothes in the drying drum is lowered. In addition, the lint which is not collected by the lint filter may reach the heat exchanger in the circulation passage and may be deposited in the heat exchanger. As a result, there has been a problem that the heat exchange efficiency of the heat exchanger is lowered and the drying performance is further lowered.

JP, 2005-177502, A International Publication No. 2005/121437

In order to solve the above problems, the clothes dryer of the present invention is detachably attachable to a drying room for storing clothes, an inlet for inserting and removing clothes into and out of the drying room, a door for closing the inlet, and a door. And a lint filter to be provided. And a door has an accommodating part which counters an insertion port and accommodates a lint filter, and a lint filter has a filter part which collects lint, and a frame part which holds a filter part. Furthermore, it has a structure which closes an insertion port in the state to which the upper end of the accommodating part of a door and the upper end of the frame part of a lint filter substantially correspond.

According to this configuration, when the user closes the inlet with the door, the door can not be closed unless the lint filter is securely accommodated in the housing of the door. Thus, the user can be made to recognize that there is a gap between the lint filter and the door, and the user can be urged to more reliably store the lint filter in the housing portion of the door. As a result, it is possible to realize a clothes dryer in which the deterioration of the drying performance is prevented.

FIG. 3 is a rear perspective view of the clothes dryer in the same embodiment. FIG. 4 is a schematic view of a heat pump device of the clothes dryer in the same embodiment.

As shown in FIGS. 1 to 4, the clothes dryer 100 according to the present embodiment includes a housing 110 and has a drying function of circulating dry air to dry clothes in the housing 110.

The housing 110 includes a front wall 111, a rear wall 112 opposite to the front wall 111, a left wall 113 erected between the front wall 111 and the rear wall 112, and a left wall 113. It is comprised from the right wall 114 on the opposite side, and the top wall 115 which obstruct | occludes the area | region enclosed by those upper edges. The front wall 111 of the housing 110 is formed with an insertion port 116 through which the user houses the clothes in the housing 110.

Moreover, as shown in FIG. 1 and FIG. 2, the clothes dryer 100 is provided with the door 120 which has the handle 123 for opening and closing attached to the front wall 111. As shown in FIG. The door 120 is pivoted between the open position and the closed position by the body connection hinge 125 (see FIG. 7B). In addition, the door 120 shown in FIG. 1 has shown the state of the closed position.

Here, the drying operation of the clothes in the clothes dryer according to the present embodiment will be briefly described below.

First, the user pulls the opening / closing handle 123 provided on the door 120 to the front side, moves the door 120 to the open position, and opens the insertion port 116. Then, the user stores the clothes in the housing 110 through the insertion port 116. Thereafter, the user moves the door 120 to the closed position and closes the insertion port 116. At this time, the door 120 is fixed at the closed position by the door lock lever 124 (see FIG. 7B).

Next, when it is detected that the door lock lever 124 is closed on the main body side of the clothes drier 100, the control unit 200 shown in FIG. And drying of the clothes thrown in in the rotating drum 320 which comprises a drying chamber is started.

The clothes are dried by the above operation.

Further, as shown in FIG. 1, the clothes dryer 100 according to the present embodiment further includes an operation panel 201. The operation panel 201 is used as part of the front wall 111 of the housing 110. The user can set various driving courses by operating the operation panel 201.

Then, the clothes dryer 100 executes the drying operation based on the course information output from the operation panel 201. At this time, the user moves the door 120 to the open position and inserts the clothes into the rotating drum 320 through the insertion port 116 in advance. Thereafter, the door 120 is moved to the closed position, and the clothes drying operation is performed.

In addition, the rotating drum 320 which comprises a drying chamber has a bottomed cylindrical shape. The rotary drum 320 is disposed so that the axial center of the rotary shaft of the rotary drum 320 is horizontal and the insertion port 116 is on the front side.

Further, as shown in FIG. 2 and FIG. 3, a double-axis drive motor 310 is provided on the bottom of the clothes dryer 100. A drum drive pulley 311 that rotationally drives the rotary drum 320 is provided on the front side rotary drive shaft 310 a of the dual shaft drive motor 310. A drum drive belt 312 mounted on a drum drive pulley 311 is mounted on the outer periphery of the rotary drum 320. On the other hand, a fan drive pulley 313 for rotationally driving the blower fan 331 is provided on the rear rotation drive shaft 310 b of the dual shaft drive motor 310. The driving force of the both-axis drive motor 310 is transmitted to the blower fan 331 via the fan drive belt 314 constructed on the fan drive pulley 313.

At this time, the blower fan 331 is disposed downstream of the heat pump device 420 and sucks the drying air of the upstream blower passage 480. Then, the blower fan 331 sends the drying air to the downstream blower passage 332 of the fan case 330.

Also, by the rotation of the both-axis drive motor 310, the clothes contained in the rotary drum 320 are lifted in the rotational direction, and the stirring operation of dropping from the height of the lifted appropriate position is repeated. At this time, the drying air is fed into the rotating drum 320 from the circulation duct 430 by the rotation of the blower fan 331.

Then, as described above, the drying air flows into the rotating drum 320 where the clothes are stirred, and the clothes are efficiently collided. As a result, the garment is properly dried.

Further, as shown in FIG. 2, the circulation duct 430 for circulating the drying air of the clothes dryer 100 according to the present embodiment includes a lint filter 510, a filter 482, a heat pump device 420, and a fan for storing a blower fan. And a case 330. The fan case 330 is connected to a back plate 117 provided between the rotary drum 320 and the rear wall 112 of the housing 110. The lint filter 510 is housed in the housing portion of the door 120 and collects lint. The filter 482 is provided below the clothes dryer 100 and upstream of the heat pump device 420, and collects foreign matter that has passed through the lint filter 510. Furthermore, the circulation duct 430 is configured to include an upstream air flow path 480 located between the lint filter 510 and the filter 482.

Further, the clothes dryer 100 according to the present embodiment includes a heat pump device 420 shown in FIG. 4 that exchanges heat with the drying air that has passed through the rotary drum 320 in the circulation duct 430. At this time, the heat pump device 420 is disposed on the flow path of the drying air flowing from the rotary drum 320 to the blower fan 331. Then, the heat pump device 420 exchanges heat with the air flowing toward the blower fan 331 to create dry air at high temperature and supply the air into the rotating drum 320.

Further, as shown in FIG. 4, the heat pump device 420 has a dehumidifying part 421 disposed in the circulation duct 430 for dehumidifying air, and a heating part 422 for heating the air. At this time, when the drying air that has passed through the lint filter 510 passes through the dehumidifying unit 421 of the heat pump device 420, the drying air is dehumidified and the humidity of the drying air decreases. Then, the dehumidified drying air passes through the heating unit 422 and is heated. That is, the heat pump device 420 exchanges heat with the moist drying air that has passed through the rotary drum 320 to create a high temperature, low humidity drying air for drying the clothes.

Below, the structure of the heat pump apparatus in the clothes dryer of this Embodiment is demonstrated in detail with reference to FIG.

As shown in FIG. 4, the heat pump device 420 includes at least a compressor 423, an expansion valve 424, a first circulation tube 425, and a second circulation tube 426. The compressor 423 compresses a working medium (for example, a refrigerant). The expansion valve 424 reduces the pressure of the working medium. The first circulation tube 425 guides the working medium flowing from the expansion valve 424 to the compressor 423. The second circulation tube 426 guides the working medium flowing from the compressor 423 to the expansion valve 424. The first circulation tube 425 and the second circulation tube 426 form a closed loop passing through the compressor 423 and the expansion valve 424. Further, the first circulation tube 425 and the second circulation tube 426 are provided to project into the circulation duct 430 for guiding the air drawn by the blower 410.

At this time, specifically, the working medium flowing through the first circulation tube 425 is decompressed by the expansion valve 424 and becomes low temperature. The working medium flowing through the second circulation tube 426 is compressed by the compressor 423 to a high temperature.

Further, the first circulation tube 425 of the heat pump device 420 is folded back in a large number in the circulation duct 430 to define the flow path of the working medium, and the folded back first circulation tube 425 has a large number of fins attached thereto. There is. Thus, the first circulation tube 425 and the fins 427 in the circulation duct 430 constitute the dehumidifying part 421 of the heat pump device 420.

Similarly, the second circulation tube 426 of the heat pump device 420 is folded back in multiples in the circulation duct 430 to define the flow path of the working medium, and the folded back second circulation tube 426 has a large number of fins attached thereto. ing. Thus, the second circulation tube 426 and the fins 428 in the circulation duct 430 constitute the heating portion 422 of the heat pump device 420.

Next, the operation of the heat pump apparatus in the clothes dryer and the flow of the drying air will be specifically described.

First, the drying air flowing in the circulation duct 430 is cooled by the first circulation tube 425 and the fins 427 which are cooled by the low temperature working medium which constitutes the dehumidifying part 421. As a result, the water vapor in the drying air condenses on the first circulation tube 425 and the fins 427. Thus, the drying air is dehumidified.

Thereafter, the dehumidified drying air is heated by the second circulation tube 426 and the fins 428 which are heated by the high temperature working medium which constitutes the heating portion 422. As a result, the drying air becomes a high temperature dry air suitable for drying clothes.

That is, the dehumidifying unit 421 and the heating unit 422 exchange heat with the air flowing in the circulation duct 430 to create drying air.

Then, the blower fan 331 sucks the drying air that has been dehumidified and heated by the heat pump device 420, and sends the drying air to the downstream blower path 332 of the fan case 330. The delivered drying air flows into the space 450 between the bottom of the rotary drum 320 and the back plate 117 through the opening 432 of the back plate 117.

Thereafter, the drying air flows into the rotating drum 320 through a number of vents (not shown) formed in the bottom wall 321 of the rotating drum 320. The inflowing drying air collides with the clothes while passing through the rotary drum 320. By this, the clothes are dried. At this time, the drying air discharged from the rotary drum 320 takes in water vapor and the like from the clothes and has high humidity. At the same time, dust such as lint generated from the clothes and hair attached to the clothes is taken up in the drying air discharged from the rotating drum 320 and floats.

Thereafter, high humidity drying air containing dust such as lint is sent to the door air vent 122 (see FIG. 6) of the housing portion 121 attached to the back side of the door 120. The drying air sent to the door air vent 122 passes through the lint filter 510. At this time, the lint filter 510 collects and removes dust such as lint floating in the drying air.

Furthermore, the drying air that has passed through the lint filter 510 passes through the upstream air flow path 480 and passes through the filter 482. The lint passing through the lint filter 510 is collected by the filter 482 and removed.

Thereafter, the drying air flows into the heat pump device 420 from the suction inlet 481, is dehumidified by the dehumidifying unit 421, and is heated by the heating unit 422. The drying air that has been dehumidified and becomes high temperature is again sucked by the blower fan 331 via the suction outlet 429 and sent out to the downstream blower path 332.

By the operation of the heat pump apparatus described above and the flow of drying air, the drying air circulates in the circulation duct 430 and the rotating drum 320 to dry the clothes.

Hereinafter, the configuration of the lint filter 510 in the clothes dryer of the present embodiment will be described using FIGS. 5 to 10B.

FIG. 5 is a front perspective view of the door of the clothes dryer according to the embodiment of the present invention. FIG. 6 is a rear perspective view of the door of the clothes dryer in the same embodiment. FIG. 7A is a side view of the door of the clothes dryer in the same embodiment. FIG. 7B is a rear view of the door of the clothes dryer in the same embodiment. FIG. 8 is a cross-sectional view taken along line 8-8 shown in FIG. 7B. 10A and 10B are perspective views showing the upper part of the door of the clothes dryer in the same embodiment.

As described above, the lint filter 510 according to the present embodiment collects dust such as floating lint in the drying air discharged from the rotating drum 320.

Here, the lint filter 510 is configured to be detachably inserted into the housing portion 121 of the door 120 from above while the door 120 is open.

On the other hand, the filter 482 is detachably provided, for example, from below the front wall 111 of the housing 110 at the suction inlet 481 connected to the heat pump device 420 on the downstream side of the upstream air flow path 480. The filter 482 is made of, for example, a sponge member.

The lint filter 510 and the filter 482 are removed from the lower side of the housing portion 121 of the door 120 and the front wall 111 of the housing 110, and lint deposited and removed is removed. This enables maintenance of the lint filter 510 and the filter 482. Then, dust such as lint contained in the circulating drying air can be almost certainly removed by the lint filter 510 and the filter 482.

Further, as shown in FIGS. 6 to 8, the lint filter 510 is configured by at least a mesh filter 511 constituting a filter portion, a frame portion 512, a seal packing 513, a lock portion 514 and the like. The mesh filter 511 collects and removes dust such as lint. The frame 512 fixes and holds the mesh filter 511. The seal packing 513 is provided on the back side of the lint filter 510 (the door air vent 122 side of the housing portion 121), and functions as a sealing portion. In addition, the seal packing 513 is in contact with the pressure contact wall 126 of the housing portion 121 of the door 120 shown in FIG. 8 to maintain the airtightness of the housing portion 121 and the lint filter 510. The sealing portion may be provided, for example, on the door 120 side, as long as the sealing portion has a configuration that maintains the airtightness of the door 120 and the lint filter 510.

Furthermore, the lock portion 514 is provided on the top of the lint filter 510, and locks and locks the lint filter 510 to the housing portion 121 of the door 120.

Further, the lock portion 514 includes a locking mechanism 516 for locking the lint filter 510 to the door 120 and an operation portion 517 for moving the locking mechanism 516 to the left and right.

Then, as shown in FIG. 7B, when the lint filter 510 is housed in the housing portion 121 of the door 120, the lock portion 514 is closed with the operation portion 517 of the lock portion 514 positioned at the center, It slides open and opens in the state of being located on the right.

Specifically, when the operation portion 517 of the lock portion 514 and the locking mechanism 516 are in the position shown in FIG. 6, the recess 129 of the housing portion 121 and the locking mechanism 516 are as shown by solid arrow A in FIG. No match (see FIG. 10B). Therefore, the lint filter 510 can not be accommodated in the accommodation portion 121. Therefore, as shown in FIG. 6, the lint filter 510 slides the operation portion 517 of the lock portion 514 to the right to move the locking mechanism 516 to the right to bring the lock portion 514 into the unlocked state. In that state, the lint filter 510 is accommodated in the accommodation portion 121 of the door 120 from above. At this time, as shown by the broken line arrow B in FIG. 6, the positions of the concave portion 129 of the housing portion 121 and the locking mechanism 516 are matched. As a result, the locking mechanism 516 of the lock portion 514 is fitted into the recess 129 located at the upper portion of the housing portion 121. Then, when the operation portion 517 of the lock portion 514 is slid to the left in the fitted state, the locking mechanism 516 moves from the recess 129 of the accommodation portion 121 to the left, and the lint filter 510 is accommodated in the door 120 (See FIG. 10A). Thus, the lint filter 510 can be reliably housed in the housing portion 121 of the door 120.

Moreover, as shown to FIG. 7A, the communication port 130 connected to the upstream ventilation path 480 is provided under the accommodating part 121 of the door 120 in which the lint filter 510 is accommodated. Therefore, the drying air circulated by the blower fan 331 passes through the lint filter 510 housed in the housing portion 121 from the rotary drum 320 through the door blower holes 122 of the door 120. Thereafter, the drying air passes from the communication port 130 of the housing portion 121 toward the upstream air flow path 480.

The lint filter 510 which is repeatedly attached and detached is desired to be simplified or easily attached and detached in consideration of maintenance and the like. In addition, it is also desirable to ensure sealing performance so that the drying air does not leak from the circulation duct 430 and the drying performance is not reduced. Similarly, lint and the like contained in the drying air leak from the circulation duct 430, and high sealing performance is required so as not to contaminate the outside of the clothes dryer 100.

Therefore, a protrusion 515 is further provided on the side surface 512b of the frame 512 of the lint filter 510 according to the present embodiment in order to simplify attachment and detachment and to ensure high sealing performance.

Hereinafter, the operation and effects of the projecting portion 515 provided in the lint filter 510 of the present embodiment will be described with reference to FIGS. 9A to 9C.

FIG. 9A and FIG. 9B are side sectional views showing a part of the door of the clothes dryer in the same embodiment. FIG. 9C is an enlarged view of a portion C shown in FIG. 9A.

As shown in FIG. 9A, the lint filter 510 moves along, for example, a groove-like guide portion 127 in which the protrusion 515 is disposed inside the accommodation portion 121 of the door 120. Thus, the lint filter 510 is guided to and stored in the correct position of the housing portion 121 of the door 120. That is, since the guide portion 127 of the housing portion 121 guides the projecting portion 515 of the lint filter 510, the lint filter 510 can be easily attached to the housing portion 121. In addition, since the lint filter 510 can be correctly mounted in the housing portion 121, it can be mounted at an incorrect position to prevent air from leaking out.

Further, as shown in FIG. 9A, the guide portion 127 further has a bent portion 128 below the guide portion 127 (on the side of the communication port 130). The bending portion 128 is configured such that the upper portion 128 a and the lower portion 128 b of the bending portion 128 have a predetermined angle.

At this time, as shown in FIG. 9B, when the lint filter 510 is housed in the housing portion 121, the projecting portion 515 moves along the angle of the bending portion 128 to the pressure contact wall 126 side of the housing portion 121. Then, the seal packing 513 of the lint filter 510 is pressed against the pressure contact wall 126 side of the housing portion 121, and the lint filter 510 is housed in the housing portion 121. As a result, the lint filter 510 can be reliably housed in the housing portion 121 without rattling, and it can be difficult to remove. The bent portion 128 is bent in a direction in which the seal packing 513 of the lint filter 510 is pressed against the pressure contact wall 126 of the housing portion 121. Therefore, the adhesion between the lint filter 510 and the housing portion 121 by the seal packing 513 can be enhanced. Thereby, the leakage of air from the gap between the lint filter 510 and the housing portion 121 can be prevented, and the drying performance can be enhanced.

Further, as shown in FIG. 8, the pressure contact wall 126 of the housing portion 121 in contact with the seal packing 513 of the lint filter 510 is configured to be inclined from the housing port 121 b of the housing portion 121 to the communication port 130 in the vertical direction. . That is, the lint filter 510 is disposed to be inclined so as to be on the wall surface of the pressure contact wall 126. Specifically, in a state where the door 120 is closed, the upper portion 126a of the pressure contact wall 126 protrudes more toward the insertion port 116 than the lower portion 126b, and the lower portion 126b is thicker than the upper portion 126a in the cross section of the pressure contact wall 126. The pressure contact wall 126 is inclined to be thick. That is, the inner surface of the housing portion 121 has a sloped surface having a substantially trapezoidal shape (including a trapezoidal shape) when viewed in cross section. Therefore, the lint filter 510 is in pressure contact with the pressure contact wall 126 of the housing portion 121 by the weight of the lint filter 510. As a result, the seal packing 513 of the lint filter 510 provided on the surface facing the pressure contact wall 126 can further improve the airtightness between the lint filter 510 and the housing portion 121.

Further, as shown in FIG. 9A, the attachment surface of the seal packing 513 attached to the lint filter 510 has a substantially trapezoidal shape (trapezoid shape) having a reverse slope surface whose shape substantially matches (includes) the inner surface of the accommodation portion 121. (Inclusive). Specifically, in a state in which the door 120 is closed, the upper portion 510a of the mounting surface of the seal packing 513 of the lint filter 510 is formed to project more toward the inlet 116 than the lower portion 510b. Therefore, the weight of the lint filter 510 works in a direction in close contact with the pressure contact wall 126, and the seal structure can be configured more reliably. Thus, it is possible to prevent the leakage of lint and the like from the air passage between the door air vent 122 and the communication port 130 and the leakage of the drying air with a simple seal structure. As a result, the drying performance by the circulation of the drying air and the functions of dehumidifying and heating the heat pump device 420 can be secured.

In addition, the lint filter 510 can securely attach and fix the lint filter 510 to the door 120 by the lock portion 514 disposed on the upper portion of the frame portion 512. At this time, the lint filter 510 needs to be normally fixed to the housing portion 121 by the lock portion 514.

Therefore, the lint filter 510 has the following configuration so that the door 120 can not be closed when the lint filter 510 is not accommodated in the accommodation part 121 properly.

That is, as shown in FIG. 9B, the door 120 can be closed in a state where the upper end 512a of the frame portion 512 of the lint filter 510 and the upper end 121a of the accommodation portion 121 substantially coincide (including coincidence). On the other hand, when the upper end 512a of the frame portion 512 and the upper end 121a of the accommodation portion 121 do not substantially coincide with each other, the lint filter 510 comes in contact with the insertion port 116 and the door 120 can not be closed normally.

Further, as shown by the solid-line arrow A in FIG. 6, the locking mechanism 516 of the locking portion 514 is the housing portion 121 even when the lint filter 510 is to be stored in the housing portion 121 with the lock portion 514 being slid in the locking state. Interfere with the top edge 121a of the Therefore, the lint filter 510 can not be normally accommodated in the accommodation portion 121 (see FIG. 10A). Therefore, as shown by the broken-line arrow B in FIG. 6, the locking mechanism 516 of the lint filter 510 is inserted into the recess 129 of the housing 121 with the lock 514 unlocked (the operation 517 slid to the right). Then, the control unit 517 of the lock unit 514 is slid to the left to bring it into the closed state. (See FIG. 10B).

The lint filter 510 is configured as described above, and the door 120 can not be closed if it is not properly accommodated in the accommodation portion 121. As a result, the drying operation can be performed in a state in which the lint filter 510 and the pressure contact wall 126 of the housing portion 121 maintain sealing performance.

In addition, the lint filter 510 can be prevented from being mounted at an incorrect position of the housing portion 121. Thus, air can be prevented from leaking from the pressure contact surface between the lint filter 510 and the housing portion 121. In addition, it is possible to prevent the lint and the like from leaking out of the air passage between the door air vent 122 and the communication port 130. As a result, it is possible to ensure the drying function by the circulation of the drying air and the functions of dehumidification and heating of the heat pump device.

When the user tries to close the door 120 without locking the lock portion 514, the door 120 can not be closed. For example, an elastic body such as a spring may be provided under the lock portion 514. . In this case, when the lock portion 514 is in the unlocked state without being locked, the upper end of the lock portion 514 (for example, the upper end of the operation portion 517) interferes with the insertion port 116 due to the pushing force of the spring which is an elastic body. Therefore, the door 120 can not be closed. Therefore, the lock portion 514 is pushed downward against the elastic repulsive force of the spring and slid left so as to be in the closed state (see FIG. 10B), and the upper end of the lock portion 514 does not interfere with the insertion port 116 Lower to height. Thus, it is possible to more reliably attach the lint filter 510 to the accommodation portion 121 by preventing the locking of the lock portion 514 of the lint filter 510 from being forgotten. As a result, during the drying operation, the lint filter 510 can be prevented from floating upward and the sealing performance being lowered. Further, it is possible to more reliably prevent leakage of lint or the like from the air passage between the door air vent 122 and the communication port 130 and leakage of the drying air. As a result, the drying performance by the circulation of the drying air and the functions of dehumidifying and heating the heat pump device 420 can be secured.

Further, the lint filter 510 may use an elastic body such as a spring described above as the lock portion 514 so that the lock portion 514 can be locked in a state where the upper end of the frame portion 512 and the upper end of the accommodation portion 121 substantially coincide. Set up. At this time, the lock portion 514 pushed down by the elastic body comes in contact with the housing portion 121 of the door 120, and the lint filter 510 is pushed down via the lock portion 514. Thereby, it is possible to prevent the lint filter 510 from floating upward and the sealing performance from being reduced during the drying operation. In addition, it is possible to prevent the leakage of lint and the like from the air passage between the door air vent 122 and the communication port 130 more reliably. As a result, the drying performance by the circulation of the drying air and the functions of dehumidifying and heating the heat pump device 420 can be secured.

In addition, even if the user tries to slide the lock portion 514 disposed at the upper portion of the lint filter 510 in the locked state, the lock portion 514 does not completely reach the bent portion 128 of the guide portion 127. For example, it may be configured to simply interfere. Thereby, the user can easily confirm the misuse state. As a result, the lint filter 510 can be mounted at the wrong position of the housing portion 121 to prevent the air from leaking out and improve the drying performance.

As described above, according to the clothes dryer of the present invention, the drying chamber for storing clothes, the insertion opening for inserting and removing the clothes into and out of the drying chamber, the door for closing the insertion opening, and the door are removable. And a lint filter provided in And a door has an accommodating part which counters an insertion port and accommodates a lint filter, and a lint filter has a filter part which collects lint, and a frame part which holds a filter part. Furthermore, it may have a structure which closes an insertion port in the state to which the upper end of the accommodating part of a door and the upper end of the frame part of a lint filter substantially correspond.
