It is preferable to measure the temperature of the transmitted dehumidified water.

  According to the above configuration, the tube wall of the fixed element includes the inner wall surface that defines the drainage channel through which the dehumidified water flows, and the outer wall surface against which the measurement element is pressed. Since the measuring element pressed against the outer wall surface by the elastically deformed signal line measures the temperature of the dehumidified water transmitted through the tube wall, the temperature sensor for measuring the dryness of the clothing is stably used for the dehumidified water. The temperature can be measured.

  In the above configuration, it is preferable that the fixing element includes a holding cylinder that protrudes from the outer wall surface and holds the measurement element, and the holding cylinder is formed with a slit for inserting the signal line.

  According to the above configuration, the holding cylinder of the fixed element protrudes from the outer wall surface and holds the measuring element.

  The dryer 100 further includes a door body 130 that is rotatably attached to the front wall 111. The user can open the door 130 and put the clothes into the main casing 110 or take out the clothes in the main casing 110.

  FIG. 4 is a perspective view of the dryer 100 showing various elements disposed in the main housing 110. 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.

  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. When the drive motor 230 is operated, the driving force is transmitted to the rotating drum 220 through the driving belt 232 and the rotating shaft 231, and the rotating drum 220 rotates in the water tank 210. In the present embodiment, the drive motor 230 is exemplified as a drive source.

  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. In the present embodiment, the damper element 240 and the suspension element 245 are exemplified as support elements.

  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 330 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 drain 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 drain 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. In this embodiment, the drain pipe 360, the drain valve 361, and the drain port 362 are illustrated as a drainage system.

  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 drain valve 361 opens the drain pipe 360, the dehumidified water used to dehumidify the dry air is also discharged out of the main housing 110 through the drain port 362.

  The drain pipe 360 includes the filter unit 500. 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. In the present embodiment, the filter unit 500 is exemplified as a fixed element.

  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. In the present embodiment, the heat exchanger 400 is exemplified as a dehumidifying element.

  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.

  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.

  FIG. 7 is a side view of the heat exchanger 400. The flow of dry air from the heat exchanger 400 toward the filter device 700 will be described with reference to FIGS. 5 and 7.

  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. In the present embodiment, the heat exchange tube 410 is exemplified as a guide tube.

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

  The first outer shell body 430 and the second outer shell body 440 form a flow path 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 outer shell 440 that is substantially parallel to the center line L <b> 1 of the exhaust port 413 extends 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 substantially 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 passes through the heat exchange pipe. It reaches the inner surface 411 of 410. 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.

  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 is likely to fluctuate. . 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.

(Upper unit)
FIG. 13 is a perspective view of the upper unit 720. FIG. 14 is a cross-sectional view of the upper unit 720. The upper unit 720 will be described with reference to FIGS. 3, 10, 12 to 14.

The second housing 770 includes a support cylinder 771 that is substantially complementary to the rotation protrusion 762. A rotation protrusion 762 formed at the upper right end of the first housing 760 is inserted through the support cylinder 771. As a result, the first housing 760 is rotatably supported and coupled to the second housing 770. In the present embodiment, a rotation protrusion 762 is formed on the first housing 760, and a support cylinder 771 is formed on the second housing 770. Alternatively, a support cylinder may be formed in the first housing, and a rotating shaft may be formed in the second housing.

  FIG. 16 is a right side view of the first housing 760. The first housing 760 is described with reference to FIGS. 10, 13, and 16.

  As shown in FIG. 10, the first housing 760 is completely accommodated in the upper space US. As shown in FIG. 16, the first housing 760 includes a right side wall 764 in which an opening 763 is formed. The dry air that has passed through the inflow port 731 flows into the first housing 760 through the opening 763. The upper filter portion 725 attached to the grid-like inclined surface 761 captures lint in the dry air.

  As shown in FIG. 13, when the left end of the first housing 760 is in the first housing 760 at the first position connected to the second housing 770, the first housing 760 and the second housing 770 are In cooperation with each other, an accommodation space for accommodating the lint captured by the upper filter portion 725 is formed.

  FIG. 17 is a schematic cross-sectional view of the upper unit 720 having the first housing 760 rotated to the right. A method of removing lint from the upper unit 720 will be described with reference to FIGS. 13, 16, and 17.

  When the first housing 760 rotates in the separating direction (the right direction in FIG. 17) in which the left end of the first housing 760 is separated from the second housing 770, the lint captured by the upper filter portion 725 can be removed. Become.

  FIG. 18 is a schematic front view of the upper unit 720 having the first housing 760 that is further rotated in the separation direction. The rotation of the first housing 760 will be described with reference to FIGS. 15 to 18.

  The first housing 760 can be further rotated in the separation direction around the rotation protrusion 762. As shown in FIG. 15, the lid body 750 that largely protrudes to the right includes a right edge 751. As shown in FIG. 18, the right edge 751 contacts the right side wall 764 of the first housing 760 that rotates in the separation direction, and restricts the rotation of the first housing 760. In the following description, the position of the first housing 760 whose rotation is restricted by the lid 750 is referred to as a second position.

  In FIG. 18, when the lid 750 is removed from the second housing 770, the first housing 760 rotated to the maximum distance from the second housing 770 is indicated by a dotted line. . As shown in FIG. 18, when the lid body 750 is removed from the second housing 770, the first housing 760 can be further rotated in the separation direction from the second position. Second housing 770 includes a connection portion 772 used for connection with lid 750. The connecting portion 772 protrudes outward. After the lid 750 is removed from the second housing 770, when the first housing 760 is rotated in the separating direction as much as possible, the right side wall 764 of the first housing 760 is connected to the second housing 770. Part 772 is contacted.

(Connection structure between the first housing and the second housing)
FIG. 19 shows the rotation protrusion 762 of the first housing 760. FIG. 19A is a right side view of the first housing 760. FIG. 19B is a partial front view of the rotating protrusion 762 protruding in the front direction, and represents the end face shape of the rotating protrusion 762. FIG. 19C is a partial rear view showing the end face shape of the rotation protrusion 762 protruding in the rear direction. The rotation protrusion 762 will be described with reference to FIG.

  The rotation protrusion 762 includes a first rotation protrusion 765 that protrudes in the front direction, and a second rotation protrusion 766 that is formed on the opposite side of the first rotation protrusion 765. The second rotation protrusion 766 protruding in the direction opposite to the first rotation protrusion 765 is formed substantially coaxially with the first rotation protrusion 765. The substantially cylindrical second rotation protrusion 766 has a substantially circular cross section. On the other hand, the 1st rotation protrusion 765 by which D cut process was carried out has a non-circular cross section.

  The peripheral surface of the first rotation protrusion 765 that has undergone the D-cut process includes a flat surface 767. The flat surface 767 includes a first flat surface 768 and a second flat surface 769 formed on the opposite side of the first flat surface 768. The second flat surface 769 is substantially parallel to the first flat surface 768. The peripheral surface of the first rotation protrusion 765 further includes an arcuate surface 781 between the first flat surface 768 and the second flat surface 769.

  FIG. 20 shows the support cylinder 771 of the second housing 770. FIG. 20A is a right side view of the second housing 770. FIG. 20B is a partial cross-sectional view of the second housing 770 viewed from the direction of the arrow A shown in FIG. 20A, and shows the support cylinder 771 into which the first rotation protrusion 765 is inserted. FIG. 20C is a partial cross-sectional view of the second housing 770 viewed from the direction of the arrow B shown in FIG. The support cylinder 771 is described with reference to FIGS. 19 and 20.

  The support cylinder 771 includes a first support cylinder 773 that supports the first rotation protrusion 765 and a second support cylinder 774 that supports the second rotation protrusion 766. 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.

  The second support cylinder 774 includes a facing surface 776 that faces the first support cylinder 773. The first support cylinder 773 includes a first portion 777 spaced from the facing surface 776 by a first distance D1 and a second portion 778 spaced from the facing surface 776 by a second distance D2. The second distance D2 is longer than the first distance D1.

  The first portion 777 includes an edge 779 that defines a gap G formed at the boundary between the first portion 777 and the second portion 778. The gap G opens in the radial direction with respect to the rotation axis RX of the rotation protrusion 762.

  FIG. 21 shows the first housing 760 attached to the second housing 770. 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.

  As described with reference to FIG. 18, the lid 750 prevents the first housing 760 from being rotated to the attachment position. Therefore, unless the lid 750 is removed from the second housing 770, the connection between the first housing 760 and the second housing 770 is maintained.

  As shown in FIG. 22, the edge 779 that defines the gap G includes an upper edge 782 that defines the upper boundary of the gap G and a lower edge 783 that defines the lower boundary of the gap G. The distance between the upper edge 782 and the lower edge 783 is set to be approximately equal to the distance between the first flat surface 768 and the second flat surface 769 of the first rotation protrusion 765. When the first housing 760 reaches the attachment position, the flat surface 767 is substantially orthogonal to the boundary surface B defined as a surface that passes through the upper edge 782 and the lower edge 783.

  The distance between the first flat surface 768 and the second flat surface 769 is the shortest among the cross-sectional dimensions of the first rotation protrusion 765. Therefore, when the first housing 760 is located at a position other than the mounting position, the edge portion 779 is inserted into the first support cylinder 773 or the first rotation protrusion from the first support cylinder 773. Prevent removal of 765. On the other hand, when the first housing 760 reaches the attachment position, the first rotation protrusion 765 is inserted into the first support cylinder 773 through the gap G, or the first rotation protrusion 765 passes through the gap G, 1 is separated from the support cylinder 773.

  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.

(Heat dissipation from the filter device)
FIG. 23 is a schematic cross-sectional view of the second housing 770. The second housing 770 is described with reference to FIG.

  The second housing 770 includes a bottom wall 791 lying horizontally, a peripheral wall 792 erected upward from the bottom wall 791, and a rib 793 formed on the upper surface of the bottom wall 791. The second housing 770 is formed in a dish shape as a whole, and the bottom wall 791 and the peripheral wall 792 form a recessed area that is recessed with respect to the lid 750. Ribs 793 formed on the upper surface of the bottom wall 791 extend along the upper surface of the peripheral wall 792.

  FIG. 24 is a perspective view of the upper unit 720. The upper unit 720 will be described with reference to FIGS. 1, 12, 23, and 24.

  As shown in FIG. 24, the first housing 760, the second housing 770, and the lid 750 are connected and integrated as an upper unit 720. As described with reference to FIG. 12, the lid 750 partially covers the outlet 701 formed in the top wall 115 of the main housing 110.

  The lid body 750 attached to the second housing 770 partially closes the recessed area defined by the bottom wall 791 and the peripheral wall 792 of the second housing 770. An opening 754 is formed in the lid 750. The lid 750 includes a main plate 752 having an outer surface (upper surface) exposed from the main housing 110, a handle wall 753 projecting into a recessed region defined by the bottom wall 791 and the peripheral wall 792 of the second housing 770, including. The handle wall 753 protrudes from the edge of the opening 754 into a recessed area that is recessed with respect to the main housing 110.

  FIG. 25 shows the upper unit 720. FIG. 25A is a plan view of the upper unit 720. FIG.25 (b) is sectional drawing which follows the CC line | wire shown by Fig.25 (a). Heat dissipation from the upper unit 720 will be described with reference to FIGS. 5 and 25.

  The dry air is heated by the heater 620 as described in connection with FIG. 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.

(Heat exchanger)
The heat exchanger 400 will be described with reference to FIGS. 5 and 9 again.

  As shown in FIG. 5, the heat exchanger 400 is connected to the water tank 210. Therefore, for example, in the washing process, the washing water flows into the heat exchange pipe 410 through the inflow port 412.

  As shown in FIG. 9, a conductive sensor 450 is attached to the second outer shell 440 of the heat exchanger 400. The conductive sensor 450 is used to detect the degree of foaming of the washing water that has flowed into the heat exchange tube 410. A known method may be applied to a method for detecting the degree of foaming using the conductive sensor 450. Note that other physical properties of the washing water may be measured using the conductive sensor 450.

  In the present embodiment, the conductive sensor 450 includes a first electrode 451 attached at a substantially intermediate position of the heat exchange tube 410 and a second electrode 452 attached above the first electrode 451. For example, the conductive sensor 450 measures the impedance of the washing water between the first electrode 451 and the second electrode 452. The first electrode 451 and the second electrode 452 protrude from the inner surface 411 of the heat exchange tube 410 in order to measure the physical properties of the washing water. Therefore, lint is easily caught on the first electrode 451 and the second electrode 452. A technique for supplying and guiding dehumidified water, which will be described later, facilitates removal of lint captured by the first electrode 451 and the second electrode 452.

  FIG. 26 is a schematic diagram of the heat exchanger 400. The central view of FIG. 26 is a side view schematically showing the heat exchanger 400. The left view of FIG. 26 is a schematic view of the inner surface structure of the heat exchanger 400 (that is, the inner surface structure of the first outer shell body 430) viewed from the AA direction in FIG. The right view of FIG. 26 is a schematic view of the inner surface structure of the heat exchanger 400 (that is, the inner surface structure of the second outer shell 440) viewed from the BB direction in FIG. FIG. 27 is a schematic perspective view of the second outer shell body 440. The heat exchanger 400 is further described with reference to FIGS. 4, 8, 26 and 27.

  The first outer shell 430 includes an edge surface 431 connected to the second outer shell 440 using, for example, ultrasonic waves. Similarly, the second outer shell body 440 includes an edge surface 441 connected to the edge surface 431 of the first outer shell body 430. As a result of the edge surface 431 and the edge surface 441 being overlapped and then welded, the heat exchange tube 410 is formed.

  As described with reference to FIG. 4, the dehumidified water is supplied from the drain tube 321 of the water supply unit 300 to the first water supply port 421 and the second water supply port 422. Further, as described with reference to FIG. 8, the dew condensation water is supplied as dehumidified water to the third water supply port 423 through the connection pipe 662 extending from the duct unit 660.

  The second outer shell 440 includes a storage wall 442 that surrounds the first water supply port 421 so as to temporarily store the dehumidified water flowing in from the first water supply port 421. The first outer shell 430 includes a storage wall 432 that is welded to the storage wall 442 of the second outer shell 440 using, for example, ultrasonic waves. As a result of welding the storage wall 442 and the storage wall 432, a storage chamber for storing dehumidified water flowing in from the first water supply port 421 is formed.

  As shown in FIG. 27, a notch 443 is formed in the storage wall 442 of the second outer shell 440. The dehumidified water stored in the storage chamber formed by the storage walls 442 and 432 flows down along the inner surface 411 of the second outer shell 440 through the notch 443. A similar notch (not shown) is also formed in the storage wall 432 of the first outer shell 430. The dehumidified water stored in the storage chamber formed by the storage walls 442 and 432 flows down along the inner surface 411 of the first outer shell 430 through the notch formed in the storage wall 432.

  The second water supply port 422 and the third water supply port 423 allow dehumidified water to flow into the heat exchange pipe 410 from above the second electrode 452 attached near the base end of the exhaust port 413. Therefore, the dry air is dehumidified using substantially the entire inner surface 411 of the heat exchange tube 410.

  The first outer shell body 430 and the second outer shell body 440 further include a partition plate 444 that partially partitions the flow path of dry air defined by the heat exchange pipe 410. The partition plates 444 of the first outer shell body 430 and the second outer shell body 440 are welded using, for example, ultrasonic waves. As a result of the welding, a storage chamber for storing dehumidified water flowing in from the second water supply port 422 and the third water supply port 423 is formed. A partition plate 444 extending substantially horizontally between the second water supply port 422 (and the third water supply port 423) and the second electrode 452 temporarily stores dehumidified water above the second electrode 452.

  As shown in FIG. 27, an opening 445 is formed in the partition plate 444. The dehumidified water stored in the storage chamber formed by the partition plate 444 flows down along the inner surface 411 of the second outer shell 440 through the opening 445. A similar opening (not shown) is also formed in the partition plate 444 of the first outer shell 430. The dehumidified water stored in the storage chamber formed by the partition plate 444 flows down along the inner surface 411 of the first outer shell 430 through the opening 445 formed in the partition plate 444.

  The heat exchanger 400 includes diffusion ribs 470 that diffuse the dehumidified water flowing down along the inner surface 411 substantially horizontally. The diffusion rib 470 protrudes from the inner surface 411 below the first water supply port 421. Therefore, the diffusion rib 470 can diffuse the dehumidified water supplied from the first water supply port 421, the second water supply port 422, and the third water supply port 423 as a whole. In the present embodiment, the diffusion rib 470 diffuses dehumidified water substantially horizontally. Alternatively, the diffusion ribs may diffuse the dehumidified water in any direction that intersects the flow direction of the dry air.

  The heat exchange pipe 410 includes a first side wall 425 in which a first water supply port 421 and a second water supply port 422 are formed, a second side wall 426 that faces the first side wall 425, a first side wall 425, and a second side wall 426. A main wall 427 between. The diffusion rib 470 includes a first rib 471 extending from the first side wall 425 along the main wall 427 toward the second side wall 426, and a first rib 471 extending from the second side wall 426 along the main wall 427 toward the first side wall 425. 2 ribs 472. The first ribs 471 and the second ribs 472 are substantially alternately aligned in the longitudinal direction of the heat exchange tube 410.

  The storage walls 442 and 432 form a storage chamber that stores dehumidified water together with the first side wall 425. The first rib 471 includes a base end portion 473 that receives dehumidified water from the storage chamber formed by the storage walls 442, 432 and the first side wall 425, and a tip end portion 474 opposite to the base end portion 473. . The distal end portion 474 is formed below the proximal end portion 473. Accordingly, the dehumidified water that has reached the first rib 471 flows from the base end portion 473 toward the tip end portion 474. Thus, the dehumidified water is diffused in the horizontal direction. Note that the base end portion 473 of the first rib 471 formed immediately below the storage chamber formed by the storage walls 442 and 432 and the first side wall 425 receives a relatively large amount of dehumidified water. Therefore, the base end portion 473 of the first rib 471 preferably includes a side rib 475 that extends substantially horizontally along the inner surface 411 of the first side wall 425.

  The second rib 472 includes a proximal end portion 476 adjacent to the second side wall 426 and a distal end portion 477 opposite to the proximal end portion 476. The distal end portion 477 is formed below the proximal end portion 476. Accordingly, the dehumidified water that has reached the second rib 472 flows from the base end portion 476 toward the tip end portion 477. Thus, the dehumidified water is diffused in the horizontal direction.

  In the present embodiment, the second rib 472 receives dehumidified water flowing down from the uppermost first rib 471. The lowermost first rib 471 receives dehumidified water flowing down from the second rib 472.

  FIG. 28A is an enlarged view of the uppermost first rib 471. FIG. 28B is a schematic cross-sectional view of the second outer shell 440. The diffusion rib 470 is described with reference to FIGS. 26 to 28B.

  As shown in FIG. 27, a groove portion 478 is formed in the diffusion rib 470 between the base end portions 473 and 476 and the tip end portions 474 and 477.

  FIG. 26 and FIG. 28A schematically show the flow of dehumidified water flowing down the inner surface 411. As described above, the dehumidified water that has reached the diffusion rib 470 flows toward the tip portions 474 and 477. The groove portion 478 allows a part of the dehumidified water flowing toward the tip portions 474 and 477 to flow down. Thus, the dehumidified water is diffused over the entire inner surface 411 of the main wall 427.

  27 and 28B, since the diffusion rib 470 is formed in a tapered shape, the protrusion amount of the base end portions 473 and 476 from the inner surface 411 of the main wall 427 is the protrusion amount of the distal end portions 474 and 477. Bigger than. As described above, a part of the dehumidified water flowing toward the tip portions 474 and 477 flows down through the groove portion 478, so that the amount of the dehumidified water guided horizontally by the diffusion rib 470 gradually increases toward the tip portions 474 and 477. To drop. Therefore, even if it is the taper-shaped diffusion rib 470, the horizontal diffusion function with respect to dehumidified water can fully be exhibited. Furthermore, the reduction in the amount of protrusion toward the tip portions 474 and 477 does not unnecessarily provide resistance to the flow of dry air. Therefore, the circulation efficiency of dry air is unlikely to decrease.

  As shown in FIG. 26, the dry air flows from the inflow port 412 and is exhausted from the upper exhaust port 413. As shown in FIG. 27, the diffusion rib 470 includes a substantially flat inclined surface 479 that is inclined so that the amount of protrusion gradually increases toward the upper side. Therefore, the diffusion rib 470 does not give an unnecessarily large resistance to the dry air. Therefore, the circulation efficiency of dry air is unlikely to decrease.

  As shown in FIG. 26, the heat exchange pipe 410 forms a flow path that is curved in an arc shape from the inlet 412 toward the exhaust outlet 413. The diffusion rib 470 formed on the first outer shell 430 is located on the centripetal side in the curved flow path. Further, the diffusion rib 470 formed on the second outer shell 440 is located on the centrifugal side. Therefore, in the following description, the diffusion rib 470 formed on the first outer shell 430 is referred to as a centripetal rib 481 as necessary. Further, the diffusion rib 470 formed on the second outer shell 440 is referred to as a centrifugal rib 482 as necessary.

  26 shows the horizontal line HL, the inclination angle θ1 of the centripetal rib 481 with respect to the horizontal line HL, and the inclination angle θ2 of the centrifugal rib 482 with respect to the horizontal line HL. As shown in FIG. 26, the inclination angle θ2 of the centrifugal rib 482 is larger than the inclination angle θ1 of the centripetal rib 481. Therefore, the flow rate of the dehumidified water flowing down the inner surface 411 of the second outer shell 440 is smaller than the flow rate of the dehumidified water flowing down the inner surface 411 of the first outer shell 430.

  The flow velocity of the dry air along the inner surface 411 of the second outer shell body 440 on the centrifugal side is larger than the flow velocity of the dry air along the inner surface 411 of the first outer shell body 430 on the centripetal side. As described above, the flow rate of the dehumidified water flowing down the inner surface 411 of the second outer shell 440 is relatively slow, so that heat can be appropriately exchanged with dry air having a high flow rate. In addition, since the relative speed between the dehumidified water flowing down the inner surface 411 of the second outer shell 440 and the dry air along the inner surface 411 of the second outer shell 440 is reduced, the dehumidified water is difficult to roll up. Become.

  FIG. 29 is a schematic plan view of the second outer shell 440. The cleaning of the conductive sensor 450 will be described with reference to FIGS. 7, 26, 27 and 29.

  As shown in FIG. 27, an opening 453 into which the conductive sensor 450 is inserted is formed in the main wall 427 of the second outer shell 440. As shown in FIGS. 7 and 27, the second outer shell body 440 is screwed into a fixing tool 454 (see FIG. 7) such as a screw for fixing the conductive sensor 450 to the second outer shell body 440. A fixed cylinder 455 protruding in the direction is provided. In the present embodiment, an opening 453 is formed between the pair of fixed cylinders 455.

  As shown in FIG. 29, the tip 477 of the second rib 472 is formed immediately above the first electrode 451 (on the vertical line). Therefore, the dehumidified water that has been guided by the second rib 472 and reached the tip end portion 477 flows down onto the first electrode 451. Thus, the lint attached to the first electrode 451 is appropriately removed. Alternatively, the groove portion of the diffusion rib may be formed immediately above the conductive sensor. Since the dehumidified water flowing down through the groove directly contacts the conductive sensor, lint is preferably removed.

  Two first ribs 471 are formed above the second ribs 472. The groove portion 478 formed in the uppermost first rib 471 is located immediately above the tip portion 474 of the second upper rib 471. Accordingly, since the flow rate of the dehumidified water flowing down through the second upper first rib 471 increases, the dehumidified water easily collides with the first electrode 451.

  FIG. 30 is a schematic longitudinal sectional view of the heat exchanger 400. The flow of dehumidified water flowing down from the partition plate 444 will be described with reference to FIG.

  As described above, the partition plate 444 forms a storage chamber for temporarily storing dehumidified water supplied to the second water supply port 422 (and the third water supply port 423). Since the storage chamber formed by the partition plate 444 extends in a direction crossing the flow of dry air, the dehumidified water is supplied to a wide range of the inner surface 411 of the heat exchanger 400.

  FIG. 31 is a schematic enlarged longitudinal sectional view of the upper part of the heat exchanger 400. FIG. 32 is a schematic cross-sectional view of the upper portion of the heat exchanger 400. The partition plate 444 will be described with reference to FIGS. 4, 5, and 29 to 32.

  As described above, the heat exchanger 400 includes the first outer shell 430 and the second outer shell 440 superimposed on the first outer shell 430 as described above. The partition plate 444 includes a first partition plate 446 formed integrally with the first outer shell body 430 and a second partition plate 447 formed integrally with the second outer shell body 440.

  As shown in FIG. 32, the first partition plate 446 includes a first edge 448 that faces the second partition plate 447. Second partition plate 447 includes a second edge 449 connected to first edge 448. In this embodiment, the 1st edge part 448 and the 2nd edge part 449 are adhere | attached using an ultrasonic wave. Thus, the partition plate 444 forms a storage chamber straddling the first outer shell body 430 and the second outer shell body 440.

  As shown in FIGS. 30 and 31, the partition plate 444 has a plurality of openings 445. The dehumidified water is discharged from the storage chamber formed by the partition plate 444 through the opening 445.

  FIG. 32 schematically shows the arrangement of the openings 445 formed in the partition plate 444. FIG. 32 also shows a cross section of the exhaust port 413. A part of the exhaust port 413 is used as a partition plate 444. A pair of openings 445 are formed in the tube wall of the exhaust port 413. As shown in FIG. 30, the dehumidified water flowing out from these openings 445 mainly flows toward the inner surface 411 of the main wall 427 of the first outer shell 430.

  As shown in FIG. 32, the second partition plate 447 is formed with four openings 445 aligned along the inner surface 411 of the main wall 427 of the second outer shell 440. As shown in FIG. 30, the dehumidified water flowing out from these openings 445 mainly flows along the inner surface 411 of the main wall 427 of the second outer shell 440.

  As shown in FIG. 32, notches are formed at both ends of the first edge 448 of the first partition plate 446. When the first edge portion 448 and the second edge portion 449 are connected, openings 445 adjacent to the first side wall 425 and the second side wall 426 of the heat exchanger 400 are formed. These openings 445 formed at the boundary between the first edge 448 and the second edge 449 allow the dehumidified water to flow along the side walls (first side wall 425 and second side wall 426) of the heat exchanger 400. To do.

  As shown in FIG. 29, the second electrode 452 protrudes from the inner surface 411 of the main wall 427 of the second outer shell 440 between the uppermost first rib 471 and the partition plate 444. One of the openings 445 aligned along the inner surface 411 of the main wall 427 of the second outer shell 440 is formed on the vertical line VL of the second electrode 452. Therefore, the dehumidified water flowing down from the opening 445 immediately above cleans the second electrode 452 directly and suitably removes lint.

  As described above, the control device 250 controls the water supply unit 300 to supply dehumidified water to the heat exchanger 400 through the first water supply port 421 and the second water supply port 422 while dry air is flowing through the heat exchange pipe 410. Supply. If necessary, the water supply unit 300 may supply dehumidified water to the heat exchanger 400 even in a washing process in which washing water is supplied to the treatment tank 200 under the control of the control device 250.

  Since the conductive sensor 450 outputs data related to the physical property of the washing water to the control device 250, the control device 250 may control the water supply unit 300 based on the physical property data of the washing water. For example, if the physical property data of the washing water indicates adhesion of lint to the first electrode 451 and / or the second electrode 452, the control device 250 opens the drain valve 361 and sets the liquid level in the heat exchanger 400. After depressing, dehumidified water may be supplied to the heat exchanger 400.

(Grounding structure)
The grounding structure of the dryer 100 will be described with reference to FIGS.

  The dryer 100 operates using electric power. Accordingly, the dryer 100 includes the ground wire 101 from the viewpoint of safety. In the present embodiment, the ground wire 101 extends from the drive motor 230 and is properly grounded.

  As shown in FIG. 29, the ground electrode 460 is disposed below the water supply port 420 and protrudes into the flow path formed by the heat exchange tube 410. Since the ground electrode 460 is disposed in the vicinity of the lower end of the flow path formed by the heat exchange pipe 410, it contacts both the dehumidified water flowing down from the water supply port 420 and the washing water flowing in from the inflow port 412. The ground electrode 460 is electrically connected to the ground wire 101.

After the conductive sensor 450 that operates using electric power protrudes into the flow path formed by the heat exchange tube 410 and comes into contact with the washing water or dehumidified water, the ground electrode 460 directly contacts the water in the heat exchange tube 410. Since it contacts, the direct grounding process can be performed with respect to the water in the heat exchange pipe 410.
Therefore, the safety of the dryer 100 is improved.

  FIG. 33 is a schematic enlarged view of the lower part of the second outer shell 440. The grounding structure will be further described with reference to FIGS. 5, 29, and 33.

  A water storage region 461 surrounding the ground electrode 460 is formed on the inner surface 411 of the second outer shell 440. The water storage region 461 is recessed with respect to the inner surface 411 of the second outer shell 440. Accordingly, the dehumidified water flowing down from the water supply port 420 and the washing water flowing in from the inlet 412 are stored in the water storage region 461. Since the ground electrode 460 protrudes in the water storage region 461, the ground electrode 460 properly contacts with dehumidified water and washing water.

  The second outer shell 440 includes guide ribs 462 that protrude from the inner surface 411 of the second outer shell 440 so as to guide the dehumidified water flowing down from the water supply port 420 to the water storage region 461. The guide rib 462 includes a first guide rib 463 that directly receives dehumidified water flowing down from the lowermost first rib 471 and a second guide rib 464 that flows over the first guide rib 463. Thus, the dehumidified water properly contacts the ground electrode 460.

  FIG. 34 is a schematic enlarged cross-sectional view of the connection structure between the water tank 210 and the heat exchanger 400. The grounding structure is further described with reference to FIGS. 5, 7, 26, 29, and 34.

  As described with reference to FIG. 7, the upper rear surface of the second outer shell body 440 is along the rear wall 112 of the main housing 110. As shown in FIGS. 7 and 34, the lower portion of the heat exchanger 400 is curved in the front direction. As a result, the inlet 412 is connected to the water tank 210.

  The inner surface 411 of the second outer shell 440 in which the water storage region 461 is formed is slightly curved downward. Further, the water storage region 461 is recessed with respect to the inner surface 411. Therefore, the dehumidified water and the washing water are easily stored in the water storage area 461. FIG. 34 shows the water stored in the water storage area 461.

  As shown in FIG. 34, the ground electrode 460 protrudes within the water storage region 461. Therefore, the ground electrode 460 properly contacts the water stored in the water storage region 461.

  As shown in FIG. 34, the water storage region 461 faces the inflow port 412. Therefore, when the dehumidified water or the washing water is drained through the drain port 362, the water that has contacted the conductive sensor 450 in the heat exchanger 400 contacts the ground electrode 460 and then the heat exchanger via the inlet 412. 400 is discharged. Accordingly, water that has been properly grounded is discharged from the dryer 100. Thus, the safety of the dryer 100 is improved.

(Drainage system)
4, 5, and 34, a drainage system for discharging the washing water used for washing and the dehumidified water used for heat exchange with the dry air to the outside of the main housing 110 will be described. Explained.

  As described above, the water grounded by the ground electrode 460 flows out of the inlet 412 when the drain valve 361 is opened, and then passes through the water tank 210 connecting the drain pipe 360 and the heat exchanger 400 to the drain pipe. 360. In this embodiment, the water tank 210 is illustrated as a connection element.

  As shown in FIG. 5, the dryer 100 includes a sensor element 800 for measuring the dryness of the clothes in the treatment tank 200. The sensor element 800 includes a first temperature sensor 805 disposed immediately after the heater 620 and a second temperature sensor 810 attached to the filter unit 500. The first temperature sensor 805 measures the temperature of the dry air before the clothing is dried. The second temperature sensor 810 measures the temperature of the dehumidified water that has flowed into the filter unit 500 through the water tank 210. The degree of drying of the garment is estimated by the difference in temperature measured by the sensor element 800. A known method is suitably applied to the detection of the dryness based on the temperature difference. In the present embodiment, the second temperature sensor 810 is exemplified as a temperature sensor.

  As described with reference to FIGS. 4 and 5, the vibration caused by the processing tank 200 is appropriately damped by the damper element 240 and the suspension element 245. Therefore, the front wall 111 to which the filter unit 500 is fixed hardly vibrates. Therefore, the structure for fixing the second temperature sensor 810 is simplified.

  FIG. 35 is a schematic right side view of the filter unit 500. FIG. 36 is a schematic cross-sectional view of the filter unit 500 along the line AA shown in FIG. The mounting structure of the second temperature sensor 810 with respect to the filter unit 500 will be described with reference to FIGS. 4, 5, 35, and 36.

  As shown in FIGS. 4 and 5, the drain pipe 360 includes a connection pipe 363 that connects the filter unit 500 and the water tank 210. As shown in FIG. 5, the drain valve 361 is attached to the connection pipe 363.

  As shown in FIGS. 35 and 36, the filter unit 500 includes a connection tube 520 that fits with the connection tube 363. As shown in FIG. 36, the connection pipe 363 includes a pipe wall 525 including an inner wall surface 521 that defines a drainage channel through which dehumidified water flows, and an outer wall surface 522 opposite to the inner wall surface 521. The heat of the dehumidified water flowing into the connection cylinder 520 is transferred to the outer wall surface 522.

  The second temperature sensor 810 generates a voltage signal (hereinafter referred to as a temperature signal) corresponding to the heat transferred to the outer wall surface 522, and the temperature signal from the measurement element 811 to the control device 250. A signal line 812 for transmission. The measuring element 811 is pressed against the outer wall surface 522 and appropriately measures the temperature of the dehumidified water. As a result of the temperature signal transmitted to the control device 250 by the signal line 812 connected to the measuring element 811, the control device 250 can determine the dryness of the clothes in the treatment tank 200. The control device 250 adjusts the rotational speed of the fan 611, for example, according to the dryness of the clothes. Alternatively and / or additionally, the controller 250 adjusts the amount of dehumidified water supplied to the heat exchanger 400.

  The filter unit 500 further includes a housing cylinder 512 that houses the filter member 510. Lint and other foreign substances contained in the dehumidified water (and the washing water used for washing the clothes) washing the heat exchanger 400 are appropriately removed by the filter member 510 in the housing cylinder 512. In the present embodiment, the filter member 510 is exemplified as a filter element.

  The connection tube 520 includes a base end portion 513 connected to the housing tube 512 and a holding tube 514 protruding from the outer wall surface 522 of the base end portion 513. The holding cylinder 514 surrounds and holds the measuring element 811.

  The connecting tube 520 further includes a mounting rib 515 that stands upright from the outer wall surface 522. The signal line 812 is fixed to the mounting rib 515 using an appropriate fixing tool 516. In the section from the fixture 516 to the measuring element 811, the signal line 812 is elastically deformed so as to press the measuring element 811 against the outer wall surface 522. The holding cylinder 514 is formed with a slit 517 formed so as to appropriately hold the elastic deformation of the signal line 812. The signal line 812 is inserted into the slit 517.

  Since the filter unit 500 is fixed to the stable front wall 111, the connection structure between the second temperature sensor 810 and the filter unit 500 is simplified. Further, as shown in FIG. 4, the filter unit 500 is adjacent to the control device 250, so that the signal line 812 connecting the measurement element 811 and the control device 250 may be short. Therefore, a relay point for transmitting the temperature signal is not required. Thus, equipment for measuring the dryness of clothing is constructed at a low cost. In addition, the installation work of the second temperature sensor 810 in the dryer 100 and the maintenance work related to the second temperature sensor 810 are made efficient.

  FIG. 37 is a graph schematically showing the relationship between the mounting position of the temperature sensor and the detection sensitivity. The relationship between the temperature sensor mounting position and the detection sensitivity will be described with reference to FIGS. 5 and 35 to 37.

  As described with reference to FIGS. 35 and 36, the second temperature sensor 810 of this embodiment is attached to the filter unit 500 that is remote from the heat exchanger 400. As a result, the second temperature sensor 810 is installed in the main housing 110 with a simple mounting structure. On the other hand, since the separation of the second temperature sensor 810 from the heat exchanger 400 may reduce the temperature detection sensitivity, the present inventor has separated the second temperature sensor 810 from the heat exchanger 400. The effect of was investigated.

  The inventor made two measurements. In the first measurement, the present inventor measured the temperature of the dehumidified water by attaching a temperature sensor to the filter unit as described with reference to FIGS. In the second measurement, in order to measure the temperature of the dehumidified water immediately after being discharged from the heat exchanger, a temperature sensor was disposed in the vicinity of the water tank (that is, the connection portion between the connection pipe 363 and the water tank 210).

  The “preheating period” shown in FIG. 37 is a period that appears immediately after the start of the drying process. During this period, the temperature of the dehumidified water tends to increase. An increase in the temperature of the dehumidified water during the preheating period indicates that the clothes are rapidly drying.

  The “constant rate period” shown in FIG. 37 appears after the “preheating period”, and the temperature of the dehumidified water is substantially constant during this period. A substantially constant temperature change in the “constant rate period” indicates that the clothing is being dried.

  The “decreasing period” shown in FIG. 37 appears after the “constant rate period”, and the temperature of the dehumidified water tends to decrease during this period. The decrease in the temperature of the dehumidified water during the “decreasing period” indicates that the drying of the clothes has been substantially completed.

  As shown in FIG. 37, the tendency and timing of the temperature change of the dehumidified water at the transition from the “constant rate period” to the “decreasing period” are substantially the same in the first measurement and the second measurement. This means that the second temperature sensor 810 attached to the filter unit 500 can detect the temperature change of the dehumidified water with substantially the same sensitivity as the sensor attached near the water tank 210. . Therefore, the control device 250 can appropriately determine the dryness of the clothes based on the temperature signal from the second temperature sensor 810 attached to the filter unit 500.

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