  An input port 116 is formed in the front wall 111. The user can store clothes in the housing 110 through the insertion port 116.

  The clothes dryer 100 further includes a door 120 attached to the front wall 111. The door 120 can be rotated between an open position and a closed position by a main body connecting hinge (not shown). The door 120 shown in FIG. 1 is in the closed position. The user can pull the opening / closing handle 123 provided on the door body 120 to move the door body 120 to the open position and open the insertion port 116. Thereafter, the user can store the clothing in the housing 110 through the insertion port 116. The user can move the door 120 to the closed position and close the insertion port 116. At this time, the door 120 is closed and fixed at the closed position by a door lock lever (not shown). When the control unit (not shown) detects that the door lock lever (not shown) is closed on the main body side of the clothes dryer 100, the control unit (not shown) makes the clothes drying ready. Thereafter, the garment is dried in the rotating drum 320.

  The clothes dryer 100 further includes an operation panel 201. The operation panel 201 is used as a part of the front wall 111. The user can set various driving courses by operating the operation panel 201.

  The clothes dryer 100 performs drying according to the course information output from the operation panel 201. The user can move the door body 120 to the open position and put clothes on the rotary drum 320 through the insertion port 116.

  The rotating drum 320 as a drying chamber has a bottomed cylindrical shape, and is arranged so that the rotation axis of the rotating drum 320 is horizontal and the inlet 116 is on the front side.

  A double-axis drive motor 310 is provided on the bottom surface of the clothes dryer 100. A drum drive pulley 311 that rotationally drives the rotary drum 320 is provided on the front rotational drive shaft of the double shaft drive motor 310. A drum drive belt 312 that is installed on a drum drive pulley 311 is attached to the outer periphery of the rotary drum 320. A fan drive pulley 313 that rotationally drives the blower fan 331 is provided on the rear rotational drive shaft of the double 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 installed on the fan drive pulley 313.

  The blower fan 331 is disposed downstream of the heat pump device 420. By driving the blower fan 331, the drying air in the upstream blower path 480 is sucked, while the dry air is sent out to the downstream blower path 332 in the fan case 330. The clothes housed in the rotating drum 320 are lifted in the rotating direction by the rotation of the both-axis drive motor 310, and the stirring operation of dropping from the lifted appropriate height position is repeated. Further, drying air is sent from the circulation duct 430 into the rotating drum 320 by the rotation of the blower fan 331. A large number of holes (not shown) having a diameter of about φ5 are opened as ventilation holes on the bottom surface of the rotating drum 320 to form a downstream air passage 332 connected to the fan case 330.

  As described above, the rotating drum 320 is stirring the clothes. Therefore, the drying air that has flowed into the rotary drum 320 efficiently collides with the clothes. As a result, the garment is properly dried.

  The circulation duct 430 for circulating the drying air includes a lint filter 500 that collects lint, a heat pump device 420, and a fan case 330 that stores a blower fan. The fan case 330 is connected to a back plate 117 provided between the rotary drum 320 and the rear wall 112. The lint filter 500 includes a first lint filter 510 provided on the door 120 and a second lint filter 482 provided below the clothes dryer 100 and upstream of the heat pump device 420. The circulation duct 430 includes an upstream air flow path 480 located between the first lint filter 510 and the second lint filter 482.

  The clothes dryer 100 includes a heat pump device 420 that exchanges heat with the drying air that has passed through the rotary drum 320 in the circulation duct 430. The heat pump device 420 is disposed on the flow path of the drying air that flows from the rotary drum 320 to the blower fan 331. The heat pump device 420 exchanges heat with the air flowing toward the blower fan 331 to create high-temperature and dry air.

  The heat pump device 420 includes a dehumidifying unit 421 that dehumidifies air and a heating unit 422 that heats air. The drying air that has passed through the first lint filter 510 passes through the dehumidifying unit 421. As a result, the humidity of the air decreases. Thereafter, the drying air passes through the heating unit 422. As a result, the air is heated. Thus, the heat pump device 420 can exchange heat with the drying air that has passed through the rotary drum 320 to generate drying air for drying the clothes.

  Details of the heat pump device 420 will be described with reference to FIG. 4.

The heat pump device 420 includes a compressor 423 that compresses the working medium, an expansion valve 424 that decompresses the working medium, a first circulation tube 425 that guides the working medium flowing from the expansion valve 424 to the compressor 423, and an expansion valve 424 from the compressor 423. And a second circulation tube 426 for guiding the working medium flowing to the outside. The first circulation tube 425 and the second circulation tube 426 form a closed loop that passes through the compressor 423 and the expansion valve 424. The working medium flowing through the first circulation tube 425 becomes low temperature due to the decompression by the expansion valve 424. The working medium flowing through the second circulation tube 426 becomes high temperature due to compression by the compressor 423. The first circulation tube 425 and the second circulation tube 426 protrude into the circulation duct 430 that guides air sucked by the blower 410.

  The first circulation tube 425 defines a flow path that is folded back many times in the circulation duct 430. The heat pump device 420 includes a number of fins 427 attached to a first circulation tube 425 that is folded back inside the circulation duct 430. The first circulation tube 425 and the fins 427 in the circulation duct 430 are used as the dehumidifying part 421 described above.

The second circulation tube 426 defines a flow path that is folded back many times in the circulation duct 430. The heat pump device 420 includes a number of fins 428 attached to a second circulation tube 426 that is folded back inside the circulation duct 430. Second circulation chew in circulation duct 430 The drying air flowing in the circulation duct 430 is cooled by the first circulation tube 425 and the fins 427 cooled by the low-temperature working medium. As a result, moisture in the drying air is condensed on the first circulation tube 425 and the fins 427. Therefore, the drying air is dehumidified.

  Thereafter, the drying air is heated by the second circulation tube 426 and the fins 428 heated by the hot working medium. Therefore, the drying air becomes a high temperature and becomes a drying air suitable for drying clothes. As described above, the dehumidifying unit 421 and the heating unit 422 exchange heat with the air flowing in the circulation duct 430 to produce drying air. Therefore, the dehumidification part 421 and the heating part 422 are illustrated as a heat exchanger.

  The blower fan 331 sucks the drying air created by the heat pump device 420, while sending the drying air to the downstream blowing path 332 of the fan case 330. As a result, the drying air flows into the space between the bottom surface of the rotating drum 320 and the back plate 117 through the opening 432 of the back plate 117.

  Thereafter, the drying air flows into the rotary drum 320 through a large number of air holes (not shown) formed in the bottom wall 321 of the rotary drum 320. While the drying air passes through the rotating drum 320, the clothes collide with the drying air and are dried. Therefore, the drying air discharged from the rotating drum 320 has a high humidity. Further, dust such as lint generated from the clothes and hair attached to the clothes will float in the drying air discharged from the rotating drum 320.

  Thereafter, as indicated by the black arrow in FIG. 5B, the drying air is sent to the door body air hole 122 of the housing part 121 attached to the back side of the door body 120. The drying air sent to the door body air hole 122 passes through the first lint filter 510. At this time, the first lint filter 510 collects and removes lint floating in the drying air.

The drying air that has passed through the first lint filter passes through the upstream air blowing path 480 from the first lint filter located above to the second lint filter located below, and then passes through the second lint filter 482. The lint that has passed through the first lint filter 510 is collected and removed by the second lint filter 482. Since the first lint filter 510 is provided substantially perpendicular to the horizontal flow direction of the drying air, it passes through a part of the lint attached to the first lint filter 510 or the first lint filter 510. Since a part of lint falls downward, the first lint filter 510 is less likely to be clogged with lint.

  Thereafter, the drying air flows into the heat pump device 420 and is dehumidified and heated. The drying air that has been dehumidified to a high temperature is sucked again by the blower fan 331 via the suction outlet 429 and sent out to the downstream blower path 332. As shown by the flow of the white arrow in FIG. 2, the drying air circulates in the circulation duct 430 and the rotating drum 320.

  Hereinafter, the configuration of the lint filter 500 will be described with reference to FIGS.

  A second lint filter 482 is provided in the suction inlet 481 connected to the heat pump device 420 on the downstream side of the upstream air passage 480. The second lint filter 482 is composed of a sponge member. Both the first lint filter 510 and the second lint filter 482 can be maintained by taking out and removing the accumulated lint. The lint contained in the circulating drying air can be substantially removed by the first lint filter 510.

  The second lint filter 482 is attached to the filter case 483, and after opening the front lid portion 485 that can be rotated to open and close by rotating forward, the handle portion 484 of the filter case 483 is pulled forward to be attached and detached. The second lint filter can be maintained. The lint that has passed through the first lint filter 510 is collected and removed by the second lint filter 482.

  Since the second lint filter 482 is provided substantially perpendicular to the lateral flow direction of the drying air, it adheres to a part of the lint that has passed through the first lint filter 510 or to the second lint filter 482. A part of the lint falls down and accumulates below the filter case 483, and the second lint filter 482 is less likely to be clogged with lint.

  As shown in FIG. 6, the first lint filter 510 has a mesh filter 511 (filter part) that collects and removes lint, and a frame part 512 that fixes and holds the mesh filter 511. A seal packing 513 as a sealing portion is provided on the back side of the first lint filter 510. The seal packing 513 is in contact with the press-contact wall 126 of the housing part 121 and maintains airtightness. The sealing portion may be provided on the door body 120 side as long as it is configured so that the airtightness between the door body 120 and the first lint filter 510 is maintained.

A lock portion 514 for fixing and locking the first lint filter 510 in the accommodating portion 121 is provided on the upper portion of the first lint filter 510. The lock unit 514 includes a locking mechanism 516 that locks the first lint filter 510 on the door body 120, and an operation unit 517 that moves the locking mechanism 516 left and right. The first lint filter 510 is configured so that the state where the lock portion 514 is located at the center is closed, and the state where the lock portion 514 is slid to the right and opened is located at the right.

  A communication port 130 that communicates with the upstream air blowing path 480 is provided below the housing part 121. The drying air circulated by the blower fan 331 passes through the first lint filter 510 and then passes through the upstream blower path 480 from the communication port 130.

  A filter case 483 is provided below the communication port 130 via an upstream air flow path 480. As shown in FIGS. 2, 7, and 8, as shown by the arrows in FIG. Then, the air for drying flows toward the second lint filter 482, and the lint that has passed through the first lint filter 510 is collected and removed by the second lint filter 482. The drying air that has passed through the second lint filter 482 then flows into the heat pump device 420 to be dehumidified and heated. The drying air that has been dehumidified to a high temperature is sucked again by the blower fan 331 via the suction outlet 429 and sent out to the downstream blower path 332. As shown by the flow of the white arrow in FIG. 2, the drying air circulates in the circulation duct 430 and the rotating drum 320.

  In addition, as shown in FIG. 2, the air-conditioning / fan unit according to the embodiment of the present invention is an example when applied to a heat pump dryer, and may have a configuration in which a simple heater and water-cooled dehumidification are combined. There is no limit.

  As described above, the clothes dryer according to the present invention is provided with a removable lint filter to facilitate attachment and detachment, and can suppress adhesion of lint to the lint filter, from the viewpoint of preventing deterioration of clothes drying performance. This is useful for equipment having a function of drying clothes.
