The front wall 111, the back wall 112, the left side wall 113, the right side wall 114, and the top wall 115 are removed from the dryer 100 shown in FIG. FIG. 5 is a schematic cross-sectional view of the dryer 100 showing the various elements disposed within the main housing 110. The dryer 100 is further demonstrated using FIG.1, FIG4 and FIG.5.

  As shown in FIG. 4, the dryer 100 includes a treatment tank 200 in which clothes are stored. The treatment tank 200 is formed with a loading port 201 that opens toward the front wall 111. As described with reference to FIG. 1, the user can open the door body 130 and put the clothes into the processing tank 200 through the loading port 201. Alternatively, the user can open the door body 130 and take out the clothes from the processing tank 200 through the insertion port 201. In this embodiment, the processing tank 200 is illustrated as a drying tank.

  As shown in FIG. 5, the processing tank 200 includes a water tank 210 that stores washing water used for washing clothes, and a rotating drum 220 disposed in the water tank 210. The rotating drum 220 includes a substantially cylindrical peripheral wall 221 and a bottom wall 222 facing the charging port 201. The water tank 210 includes a substantially cylindrical peripheral wall 211 that surrounds the peripheral wall 221 of the rotating drum 220, and a bottom wall 212 that extends along the bottom wall 222 of the rotating drum 220. The rotating drum 220 is disposed substantially concentrically with respect to the water tank 210.

  The dryer 100 includes a rotating shaft 231 that protrudes from the bottom wall 222 of the rotating drum 220 through the bottom wall 212 of the water tank 210 and protrudes from the bottom wall 212, a driving motor 230 disposed below the water tank 210, and a driving motor. And a driving belt 232 for transmitting the driving force of 230 to the rotating shaft 231.

  As shown in FIG. 4, the dryer 100 includes a damper element 240 that connects the bottom wall 116 of the main casing 110 and the processing tank 200, and a suspension that connects the top wall 115 of the main casing 110 and the processing tank 200. And an element 245. In the main housing 110, the damper element 240 and the suspension element 245 that support the processing tank 200 attenuate the vibration of the processing tank 200 accompanying the rotation of the rotary drum 220. Therefore, vibration from the processing tank 200 is hardly transmitted to the main casing 110.

  As shown in FIG. 4, the dryer 100 further includes a control device 250. The control device 250 controls various operations of the dryer 100. For example, when the user operates the operation panel 120 to instruct a drying operation of the dryer 100, a control signal is output and the drive motor 230 is operated.

  As shown in FIG. 1, the dryer 100 further includes a water supply port 301 for supplying water into the main housing 110. In the present embodiment, the water supply port 301 appears at a corner formed by the back edge 117 of the top wall 115 and the left edge 118 of the top wall 115.

  As shown in FIG. 4, the dryer 100 further includes a water supply unit 300 disposed below the top wall 115. The water supply unit 300 includes a control valve 310 connected to the water supply port 301 and a housing 320 including an outer surface to which the control valve 310 is fixed. A flow path (not shown) for supplying water to the processing tank 200 is formed in the housing 320.

  The dryer 100 further includes a heat exchanger 400 that exchanges heat with dry air and dehumidifies the dry air. In the case 320 of the water supply unit 300, a flow path for supplying dehumidified water used for dehumidifying dry air is formed in addition to a flow path for supplying water to the treatment tank 200. The control valve 310 switches water supply from the water supply port 301 into the housing 320 or stop of water supply under the control of the control device 250. Further, the control valve 310 opens and closes a flow path for supplying water to the treatment tank 200 and a flow path for supplying dehumidified water. For example, when the user operates the operation panel 120 to instruct the start of the washing process, the control valve 310 allows water to flow into the housing 320 under the control of the control device 250. Further, the control valve 310 opens a flow path for supplying water to the treatment tank 200. As a result, water is supplied into the processing tank 200. Alternatively, when the user operates the operation panel 120 and instructs the start of the drying process, the control valve 310 allows water to flow into the housing 320 under the control of the control device 250. In addition, the control valve 310 opens a flow path for supplying dehumidified water to the heat exchanger 400. As a result, dehumidified water is supplied into the heat exchanger 400, and the dry air is dehumidified.

  The housing 320 includes a drain tube 321 protruding rightward. When the control valve 310 opens a flow path for supplying dehumidified water to the heat exchanger 400, the dehumidified water is transferred to the heat exchanger through a connection tube (not shown) connecting the drain tube 321 and the heat exchanger 400. 400.

  The water supply unit 300 further includes a housing case 330 disposed in the housing 320. In the storage case 330, the softener used in the washing process and the detergent used in the washing process is stored.

  As shown in FIG. 1, the housing case 330 includes a handle portion 331 formed so that a user can insert a finger. The user can pull out the housing case 330 from the housing 320 using the handle portion 331. As a result, the inside of the housing case 330 is exposed outside the main housing 110. Thereafter, the user can put a detergent or a softener into the housing case 330 and push the housing case 30 into the housing 320.

  When the control valve 310 described with reference to FIG. 4 opens a flow path for supplying water to the treatment tank 200, the water flowing into the housing 320 is mixed with the detergent or softening agent in the housing case 330. Is done. As a result, in the washing process, the washing water in which the detergent in the storage case 330 and the water supplied from the water supply port 301 are mixed is supplied to the treatment tank 200. Further, in the rinsing process, a mixed liquid in which the softening agent in the housing case 330 and the water supplied from the water supply port 301 are mixed is supplied to the treatment tank 200.

  As shown in FIG. 5, the dryer 100 further includes a water supply pipe 350 that connects the water supply unit 300 and the upper part of the bottom wall 212 of the water tank 210. When the control valve 310 opens a flow path for supplying water to the processing tank 200, the water supplied from the water supply port 301 is supplied into the processing tank 200 through the water supply pipe 350.

  The dryer 100 further includes a drain pipe 360 connected to a lower portion of the peripheral wall 211 of the water tank 210 and a control valve 361 that opens and closes the drain pipe 360 under the control of the control device 250.

  As shown in FIG. 4, a drain port 362 is formed on the side surface of the bottom wall 116 of the main housing 110. The drain pipe 360 communicates with the drain port 362. When the control valve 361 opens the drain pipe 360, the water in the treatment tank 200 is discharged out of the main casing 110 through the drain port 362.

  As shown in FIG. 5, the heat exchanger 400 is connected to the lower part of the bottom wall 212 of the water tank 210. Therefore, the dehumidified water supplied from the water supply unit 300 to the heat exchanger 400 finally flows into the treatment tank 200. When the control valve 361 opens the drain pipe 360, the dehumidified water used for dehumidifying the dry air is also discharged out of the main housing 110 through the drain port 362.

  The dryer 100 includes a filter unit 500 connected to a drain pipe 360. The drain pipe 360 is connected to the drain port 362 through the filter unit 500. The filter unit 500 includes a filter member 510 for removing lint and other foreign matters from the water flowing through the drain pipe 360. Accordingly, water from which foreign matter such as lint has been removed by the filter member 510 is discharged from the drain port 362.

  The filter unit 500 is fixed to the front wall 111. As described with reference to FIG. 4, the damper element 240 and the suspension element 245 attenuate vibrations from the processing tank 200, so that the filter unit 500 is stably held on the front wall 111.

  As shown in FIG. 5, the filter member 510 includes a handle portion 511 that protrudes toward the front wall 111. As shown in FIG. 1, the front wall 111 includes a protective cover 251 that covers the control device 250, and a door portion 252 that is rotatably attached to the protective cover 251. The filter unit 500 is fixed to the protective cover 251. When the user opens the door 252, the handle 511 is exposed. The user can pick up the handle portion 511 and take out the filter member 510.

  The dryer 100 further includes a circulation system 600 that circulates dry air for drying clothes in the treatment tank 200. In addition to the heat exchanger 400 described above, the circulation system 600 includes a blower 610 that allows dry air to flow into the treatment tank 200, a duct 615 that defines a flow path of dry air from the blower 610 to the treatment tank 200, and a blower. And a heater 620 for heating dry air from 610 toward the treatment tank 200.

  As shown in FIGS. 4 and 5, the conduit 615 is connected to the peripheral wall 211 of the water tank 210 in the vicinity of the inlet 201. When the blower 610 is activated, dry air flows into the processing tank 200 through the pipe line 615. Since the heater 620 heats the dry air that flows from the blower 610 toward the treatment tank 200, the relatively high-temperature dry air is blown onto the clothing in the treatment tank 200. As a result, moisture evaporates from the clothing.

  The dry air containing the evaporated water then flows into the heat exchanger 400 connected to the bottom wall 212 of the water tank 210. As described above, since the dehumidified water supplied from the water supply unit 300 flows into the heat exchanger 400, the dry air flowing into the heat exchanger 400 is dehumidified.

  The circulation system 600 further includes a filter device 700 disposed between the blower 610 and the heat exchanger 400. The heat exchanger 400 includes a bellows tube 414 connected to the filter device 700. The lint separates from the clothes that are blown with dry air. The separated lint is then directed to the filter device 700 through the heat exchanger 400 and the bellows tube 414. The filter device 700 removes lint from the dry air. In the present embodiment, the filter device 700 is exemplified as a removal device.

  As shown in FIG. 5, the circulation system 600 further includes a duct unit 660 for guiding dry air flowing from the filter device 700 to the blower 610. Since the blower 610 makes the inside of the duct unit 660 have a negative pressure, the dry air from which the lint has been removed by the filter device 700 is directed to the blower 610 through the duct unit 660. Thus, the circulation system 600 forms a circulation path for dry air in the main housing 110.

(Connection structure between filter device and heat exchanger)
FIG. 6 is a plan view showing the internal structure of the dryer 100. A method for disassembling the main casing 110 of the dryer 100 will be described with reference to FIGS. 1 and 6.

  The top wall 115 forming the upper surface of the main housing 110 is fixed to peripheral walls such as the front wall 111, the back wall 112, the left side wall 113, and the right side wall 114 by using a fixing tool such as a screw. An operator who repairs or checks the dryer 100 can remove the fixture and remove the top wall 115 from the peripheral wall of the main housing 110. Thus, the operator can observe the inside of the dryer 100.

  The heat exchanger 400 includes a heat exchange pipe 410 that exchanges heat with dry air. The heat exchange tube 410 includes an inner surface 411 that defines a flow path through which dry air flows. The heat exchanger 400 further includes a substantially cylindrical water supply port 420 for supplying dehumidified water for dehumidifying dry air to a flow path defined by the heat exchange pipe 410. The water supply port 420 includes a lowermost first water supply port 421, a second water supply port 422 formed above the first water supply port 421, and a third water supply port 423 formed above the second water supply port 422. ,including.

  The heat exchange pipe 410 includes an inlet 412 and an exhaust port 413 formed above the inlet 412. The heat exchange pipe 410 extends toward the top wall 115 between the inflow port 412 and the exhaust port 413. As shown in FIG. 5, the inlet 412 formed at the lower end of the heat exchanger 400 is connected to the bottom wall 212 of the water tank 210. In the drying process, the dry air sent to the treatment tank 200 flows into the heat exchange pipe 410 through the inlet 412. During the washing process and the rinsing process, water (an aqueous solution containing washing water and a softening agent) supplied into the treatment tank 200 also flows into the heat exchange pipe 410 through the inflow port 412.

  The dry air that has flowed into the heat exchange pipe 410 is discharged from an exhaust port 413 formed at the upper end of the heat exchange pipe 410. Thereafter, the dry air passes through the filter device 700, the blower 610, and the heater 620, and is returned to the processing tank 200.

  FIG. 8 is a schematic layout diagram of the filter device 700, the duct unit 660, the blower 610, the heater 620, and the pipe line 615. The supply of dehumidified water to the heat exchanger 400 will be described with reference to FIGS. 1 and 4 to 8.

  Due to the drying process of the clothing in the treatment tank 200 and the heat exchange in the heat exchanger 400, the temperature of the dry air becomes lower than the temperature of the dry air immediately after the heater 620. Therefore, condensation tends to occur in the path from the filter device 700 to the blower 610.

  The duct unit 660 includes a bottom wall 661 inclined downward toward the filter device 700, and a connection pipe 662 connected to the lower end of the bottom wall 661 and the third water supply port 423 of the heat exchanger 400. Condensed water that has condensed in the duct unit 660 and has adhered to the inner surface of the duct unit 660 flows down along the bottom wall 661 by gravity. Thereafter, the dew condensation water is supplied to the heat exchanger 400 as dehumidified water through the connection pipe 662 and the third water supply port 423.

  Condensed water condensed in the filter device 700 is dropped onto the duct unit 660 by gravity and dry air. Thereafter, the dew condensation water flows down along the bottom wall 661 of the duct unit 660 and is finally supplied to the heat exchanger 400 as dehumidified water through the connection pipe 662 and the third water supply port 423.

  The blower 610 includes a fan 611 disposed in a flow path of dry air, and a drive motor 612 that rotates the fan 611. Condensed water adhering to the fan 611 is dropped onto the duct unit 660 due to the gravity action and the rotation of the fan 611. Thereafter, the dew condensation water flows down along the bottom wall 661 of the duct unit 660 and is finally supplied to the heat exchanger 400 as dehumidified water through the connection pipe 662 and the third water supply port 423.

  The duct unit 660 further includes a check valve 663 disposed at the lower end portion of the bottom wall 661. The check valve 663 suppresses dry air from flowing directly from the heat exchanger 400 into the duct unit 660.

  As described with reference to FIG. 4, the water supplied from the water supply port 301 is discharged as dehumidified water from the drain tube 321 protruding from the housing 320 of the water supply unit 300. The connection tube connected to the drain tube 321 is connected to the first water supply port 421 and the second water supply port 422 of the heat exchanger 400, respectively.

  The dehumidified water supplied into the heat exchanger 400 is guided to the inner surface 411 of the heat exchange pipe 410 and exchanges heat with dry air. As a result, the dry air is dehumidified. The dehumidified water that has flowed down along the inner surface 411 of the heat exchange pipe 410 is finally discharged from the heat exchanger 400 via the inlet 412 at the lower end of the heat exchanger 400.

  As shown in FIG. 6, the heat exchanger 400 includes a first shell 430 and a second shell 440 disposed between the first shell 430 and the back wall 112 of the main housing 110. Prepare. The second shell 440 is disposed along the back wall 112. As shown in FIG. 7, the second shell 440 is superimposed on the first shell 430 to form a heat exchange tube 410. The inflow port 412 and the exhaust port 413 are formed in the first shell 430. The water supply port 420 is formed in the second shell 440.

  The first shell 430 and the second shell 440 form a flow path that is curved in a substantially C shape. The dry air that has flowed in from the inlet 412 formed at the lower end of the heat exchanger 400 passes through the curved flow path, and is discharged from the exhaust port 413 formed at the upper end of the heat exchanger 400.

  FIG. 7 shows a horizontal line HL and a center line L1 of the exhaust port 413 formed in a substantially cylindrical shape. The heat exchanger 400 is preferably disposed in the main housing 110 so that the center line L1 of the exhaust port 413 is substantially orthogonal to the horizontal line. Therefore, the upper portion of the second shell 440 that is substantially parallel to the center line L 1 of the exhaust port 413 is along the back wall 112 of the main housing 110.

  FIG. 9 is a rear view showing a connection structure between the heat exchanger 400 and the filter device 700. The connection structure between the heat exchanger 400 and the filter device 700 will be described with reference to FIGS. 1, 6, 7, and 9.

  As shown in FIG. 9, the lower end of the bellows pipe 414 connecting the exhaust port 413 and the filter device 700 is fixed to the exhaust port 413 using a fixing band 416. Similarly, the upper end of the bellows tube 414 is also fixed to the filter device 700 using the fixing band 417.

  As shown in FIGS. 6 and 9, the filter device 700 is arranged so as to be shifted in the horizontal direction (the direction away from the right side wall 114) with respect to the center line L <b> 1 of the exhaust port 413. As described with reference to FIG. 6, the operator can remove the top wall 115. Thereafter, the operator can remove the fixing bands 416 and 417 used for fixing the bellows tube 414 and remove the bellows tube 414.

  As shown in FIG. 9, the dryer 100 further includes a conductive sensor 450 for measuring physical properties of the washing water and a ground electrode 460. The conductive sensor 450 and the ground electrode 460 protrude into the heat exchange tube 410. As described above, dry air containing lint and washing water containing lint flow into the heat exchange pipe 410. The lint in the dry air or the washing water is likely to be deposited on the conductive sensor 450 and the ground electrode 460 protruding inside the heat exchange pipe 410.

  The exhaust port 413 opens upward (that is, opens toward the top wall 115). Since the filter device 700 is shifted in a direction orthogonal to the opening direction of the exhaust port 413 (that is, the direction along the back wall 112), the operator's line of sight passes through the exhaust port 413 and the guide tube 410 Reach the inner surface. Therefore, an operator who has removed the bellows pipe 414 can observe the inside of the heat exchange pipe 410 through the exhaust port 413, and whether or not lint is accumulated on the conductive sensor 450 and / or the ground electrode 460. Can be easily confirmed.

(Filter device)
FIG. 10 is a cross-sectional view of the filter device 700 connected to the bellows tube 414. The filter device 700 is described with reference to FIGS. 1, 8, and 10.

  The filter device 700 includes a lower unit 710 and an upper unit 720 disposed above the lower unit 710. The lower unit 710 is fixed inside the main housing 110, while the upper unit 720 is easily removed from the main housing 110. The duct unit 660 described in connection with FIG. 8 is attached to the lower unit 710.

  FIG. 11 is a cross-sectional view of the lower unit 710. The lower unit 710 will be described with reference to FIGS. 10 and 11.

  The lower unit 710 includes a housing 730 for accommodating the upper unit 720. The housing 730 includes a right side wall 732 in which a substantially cylindrical inflow port 731 that protrudes toward the bellows pipe 414 is formed, and a left side wall 733 that faces the right side wall 732. The dry air flows into the filter device 700 through the bellows tube 414 and the inflow port 731.

  The lower unit 710 further includes a lower filter portion 735 connected to the right side wall 732 and the left side wall 733. The lower filter portion 735 divides the internal space formed by the housing 730 into an upper space US communicating with the inflow port 731 and a lower space LS adjacent to the upper space US. The dry air that flows in from the inflow port 731 flows into the upper space US, and then reaches the lower space LS formed below the upper space US.

  As shown in FIG. 10, the upper unit 720 is accommodated in the upper space US. The upper unit 720 includes an upper filter unit 725. The upper filter unit 725 is adjacent to the lower filter unit 735. Further, the upper filter portion 725 is substantially parallel to the lower filter portion 735.

  Dry air that has flowed in from the inflow port 731 flows into the upper unit 720 disposed in the upper space US. The dry air that has flowed into the upper unit 720 flows in the first direction FD (that is, the direction along the back wall 112) toward the left side wall 733.

  A connection portion between the lower filter portion 735 and the left side wall 733 is formed above a connection portion between the lower filter portion 735 and the right side wall 732. Accordingly, the lower filter portion 735 and the upper filter portion 725 parallel to the lower filter portion 735 are inclined with respect to the flow of dry air in the first direction FD (in FIG. 10, 0 ° <θ <90 ° (θ Is the inclination angle of the upper filter part 725 with respect to the first direction FD).

  The lower filter unit 735 and the upper filter unit 725 remove lint from the dry air that flows from the upper space US toward the lower space LS. As described above, since the lower filter portion 735 and the upper filter portion 725 are inclined with respect to the flow of the dry air in the first direction FD, a relatively wide area for removing lint is secured. In the present embodiment, the upper filter portion 725 and the lower filter portion 735 are exemplified as filter elements.

  FIG. 12 is a plan view of the dryer 100 with the upper unit 720 removed. A method for cleaning the lower filter portion 735 will be described with reference to FIGS. 3 and 10 to 12.

  As shown in FIG. 12, an outlet 701 opening upward is formed in the top wall 115 of the main casing 110. The upper unit 720 is inserted into the upper space US through the outlet 701 and attached to the main housing 110. When the upper unit 720 is removed from the main housing 110 through the outlet 701, the lower filter portion 735 is exposed.

  As described above, since the lower filter portion 735 is connected to the right side wall 732 and the left side wall 733 of the filter device 700, the user can easily observe the lower filter portion 735 through the outlet 701. it can. Therefore, the user can easily find and remove the lint accumulated on the lower filter portion 735.

  The flow of dry air in the filter device 700 will be described with reference to FIGS. 5, 6, 10, and 11.

  As shown in FIG. 10, the dry air that has flowed into the upper space US from the inflow port 731 flows in the first direction FD (the direction from the right side wall 732 toward the left side wall 733). Thereafter, the dry air flows in the downward direction DD.

  As shown in FIG. 5, the duct unit 660 extends from the filter device 700 in the front direction. Therefore, the dry air that has flowed into the lower space LS flows in the front direction (that is, the direction along the left side wall 733) and reaches the blower 610. In the following description, the flow direction of the dry air from the filter device 700 toward the blower 610 is referred to as a second direction SD.

  FIG. 6 schematically shows the flow of dry air in the first direction FD and the second direction SD. As described above, the dry air flows in the first direction FD and then flows in the downward direction DD. Thereafter, the dry air is guided in the second direction SD substantially perpendicular to the first direction FD by the casing 730 and the duct unit 660 of the lower unit 710. Such twisting of the flow of dry air occurs around the upper filter portion 725 and the lower filter portion 735. As a result, the flow of dry air around the upper filter portion 725 and the lower filter portion 735 becomes complicated, and the lint deposition position on the upper filter portion 725 and the lower filter portion 735 varies. Since lint is preferably dispersed on the upper filter portion 725 and the lower filter portion 735, the frequency of clogging of the upper filter portion 725 and the lower filter portion 735 is reduced.

  As shown in FIGS. 10 and 11, the lower space LS gradually becomes wider from the right side wall 732 to the left side wall 733 of the housing 730 of the lower unit 710. As described above, in the flow of dry air having a twisted flow, the expansion of the lower space LS in the vicinity of the left side wall 733 located in the centrifugal direction contributes to the reduction of the pressure loss of the dry air.

The support cylinder 771 includes an inner surface 775 that contacts the rotation protrusion 762. When the first housing 760 rotates, the arc-shaped surface 781 of the first rotation protrusion 765 is in sliding contact with the inner surface 775 of the first support cylinder 773. On the other hand, the flat surface 767 of the first rotation protrusion 765 is separated from the inner surface 775 of the first support cylinder 773. The peripheral surface of the second rotation protrusion 766 is in overall contact with the inner surface 775 of the second support cylinder 774.

FIG. 22 shows the first support cylinder 773 of the second housing 770 shown in FIG. 21 and the first rotation protrusion 765 of the first housing 760 shown in FIG. The connection between the first housing 760 and the second housing 770 will be described with reference to FIGS. 18 and 20 to 22.

  The rotational position of the first housing 760 shown in FIG. 21 corresponds to the position of the first housing 760 indicated by a dotted line in FIG. In the rotational position of the first housing 760 shown in FIG. 21, the first housing 760 is connected to the second housing 770. After the first housing 760 is connected to the second housing 770, the lid 750 is attached to the second housing 770. In the following description, the rotational position of the first housing 760 shown in FIG. 21 is referred to as an attachment position.

  In the present embodiment, the second rotation protrusion 766 has a cross-sectional shape different from that of the first rotation protrusion 765. Alternatively, the second rotating protrusion may have the same shape as the first rotating protrusion. The second support cylinder 774 has a shape different from that of the first support cylinder 773. Alternatively, the second support cylinder may have a mirror image shape with respect to the first support cylinder.

As shown in FIG. 25B, the bottom wall 791 and the peripheral wall 792 of the second housing 770 partition the first housing 760 and the lid 750. In addition, the bottom wall 791 and the peripheral wall 792 form an accommodation space for accommodating lint in cooperation with the first housing 760. The dry air heated by the heater 620 flows into the accommodation space as indicated by the arrow in FIG.

  The bottom wall 791 and the peripheral wall 792 are heated by heat transfer from the dry air. The rib 793 formed on the upper surface of the opening 754 of the lid 750 and the bottom wall 791 and the peripheral wall 792 facing the lid 750 promotes heat radiation from the bottom wall 791 and the peripheral wall 792. Therefore, excessive temperature rise of the bottom wall 791 and the peripheral wall 792 is suppressed.

  The user can insert a finger into the opening 754 of the lid 750 and remove the upper unit 720 from the main housing 110. As described above, since excessive temperature rise of the bottom wall 791 and the peripheral wall 792 is suppressed, even if the user's finger contacts the bottom wall 791 or the peripheral wall 792, the user does not feel excessive heat. Therefore, the dryer 100 having high safety is provided.

  The present invention is suitably used for an apparatus for drying clothes.
