(Not shown). When the main water supply valve 8b of the water supply mechanism 8 is opened, water is supplied into the water tank 7 and stored. A drain port 7b is provided at the bottom of the rear part of the water tank 7, and a drain pipe 9 is connected to the drain port 7b via a drain valve 9a. With the opening of the drain valve 9a, the water stored in the water tank 7 is discharged out of the machine through the drain pipe 9.

  Similar to the water tank 7, the rotary tank 10 is disposed in a horizontal direction with the axis line in the front-rear direction, and in a slightly upwardly inclined state. The front opening 10a of the rotating tub 10 communicates with the front opening 7a of the water tub 7 and the laundry entrance 3, and by opening the door 4, the front of the water tub 7 and the rotating tub 10 is opened from the laundry entrance 3. Clothes can be taken in and out of the rotating tub 10 through the openings 7a and 10a. As shown in FIG. 1, the rotary tank 10 has a large number of holes 10b. The hole portion 10b functions as a water passage hole through which water can move between the inside of the water tub 7 and the inside of the rotary tub 10 at the time of easy washing in the washing operation, functions as a dewatering hole at the time of dehydration, and serves as a dewatering hole at the time of drying operation. It functions as a ventilation hole that can move.

  A drum motor 11 composed of, for example, a DC brushless motor is provided on the back of the water tank 7. The rotating shaft 11 a of the drum motor 11 penetrates the back of the water tank 7 and is connected to the back of the rotating tank 10, and the rotating tank 10 is directly driven to rotate by the drum motor 11.

  Inside the outer box 2, there is provided a circulating air passage 12 located outside the water tank 7 and having both ends 13 and 16 communicating with the water tank 7. The circulation air passage 12 includes duct members 13 to 16 in which an exhaust duct 13, an intermediate duct 14, a heat pump duct 15, and an air supply duct 16 are connected in this order.

  Specifically, the water tank 7 is provided with an exhaust port 17 located at the upper right portion on the front side, and the exhaust port 17 communicates with one end of an exhaust duct 13 serving as one end of the circulation air passage 12. It is connected. A filter member 20 is disposed at a portion where the exhaust duct 13 and the intermediate duct 14 are connected to each other. Further, in the present embodiment, the adhesive member 30 for removing the lint captured by the filter member 20 is also arranged, but these members 20 and 30 will be described later in detail.

  The intermediate duct 14 extends downward from the rear of the exhaust duct 13, and is connected to one end of a heat pump duct 15 disposed below the water tank 7. In FIG. 1, for convenience of explanation, the middle part of the intermediate duct 14 is indicated by a two-dot chain line.

  The evaporator 19a and the condenser 19b of the heat pump 18 are accommodated in the heat pump duct 15. As is well known, the heat pump 18 includes a compressor (not shown) for compressing and discharging the refrigerant, a condenser 19b for condensing and liquefying the high-temperature and high-pressure refrigerant discharged from the compressor, and a condenser 19b. A refrigerating cycle is configured by connecting a throttle device (not shown) for adjusting the flow rate of the refrigerant liquefied by the above and an evaporator 19a for evaporating the refrigerant passing through the throttle device with a pipe. Among them, the condenser 19b heats the air flowing in the heat pump duct 15, and the evaporator 19a cools and dehumidifies the air flowing in the heat pump duct 15. In the heat pump duct 15, the evaporator 19 a is arranged near the connection with the intermediate duct 14, and the condenser 19 b is arranged near the air supply duct 16.

  A blower 21 is provided at a portion where the heat pump duct 15 and the air supply duct 16 are connected to communicate with each other. The blower 21 includes a fan casing 22, a fan 21a provided in the fan casing 22, and a fan motor 21b for rotating the fan 21a. The fan casing 22 has an intake port 22 a connected to the heat pump duct 15 and a discharge port 22 b connected to a lower end of the air supply duct 16. The upper end of the air supply duct 16 extends upward and is connected to an air supply port 23 provided at an upper portion on the back side of the water tank 7. Thus, the blower 21 can circulate the air in the water tank 7 through the above-described circulation air passage 12 by the rotational drive of the fan 21a.

Subsequently, the configuration relating to the filter member 20 and the adhesive member 30 will be described in detail with reference to FIGS.
As shown in FIG. 1, a portion of the intermediate duct 14 near the exhaust duct 13 is a filter housing portion 25 in which the filter member 20 is mounted. The filter housing portion 25 and the exhaust duct 13 are located immediately below the upper surface 2b of the outer box 2. Here, FIG. 2 shows an enlarged view of the internal structure of the filter accommodating portion 25 and the exhaust duct 13, and the illustration of the connecting portion (the bellows portion 13 z in FIG. 1) of the exhaust duct 13 on the exhaust port 17 side is omitted. are doing.

  As shown in FIG. 2, the filter housing portion 25 is in a hollow state in which the filter housing portion 25 communicates forward and backward at an opening 25 p on the exhaust duct 13 side, and the filter member 20 is provided at a position facing the opening 25 p. The filter member 20 is configured by a planar filter in which a net 27 is stretched on a frame 26 having a lattice shape. The frame 26 of the filter member 20 is set to have a size and shape corresponding to the opening 25p, is locked by the bottom wall 25a and the upper wall 25b of the housing portion 25, and has left and right side walls (one side wall 25c in FIG. 2). (Only shown).

  In the present embodiment, the flat front side where the mesh 27 is stretched in the filter member 20 is defined as the lint capturing surface 20a, and the side where the frame 26 projects from the mesh 27 is defined as the rear side. In other words, the air flowing through the circulation air passage 12 during the drying operation passes through the exhaust port 17, the exhaust duct 13, the filter member 20, the intermediate duct 14, the heat pump duct 15, and the air supply duct 16 in order from the exhaust port 17 as indicated by the arrow in FIG. Because of the flow, the front side of the filter member 20 becomes the lint capturing surface 20a that captures the lint.

  On the other hand, the exhaust duct 13 is an adhesive member housing section that houses the adhesive member 30 at a position near the opening 25p. As shown in FIG. 2, the vertical space of the exhaust duct 13 is larger than that of the filter accommodating portion 25 because the bottom wall 13 a is stepped down below the bottom wall 25 a of the filter accommodating portion 25. I have.

  The adhesive member 30 is a plate-like member having a rectangular shape as a whole. The vertical dimension of the adhesive member 30 is set so as to reach from the bottom wall 13a of the exhaust duct 13 to the upper end of the filter member 20 in an upright posture as shown in FIG. The dimension in a direction perpendicular to the paper surface) is set so as to match the dimension in the left-right direction of the filter member 20.

  The adhesive member 30 has an adhesive surface 30a in an area that matches the lint capturing surface 20a of the filter member 20 in the upright posture. The adhesive surface 30a is a rectangular sheet-like adhesive layer formed on one surface side of the adhesive member 30. The material of the adhesive surface 30a is made of, for example, polyurethane whose adhesive strength can be regenerated by pouring water (may be made of another material such as silicon). In other words, even if lint or the like adheres to the adhesive surface 30a and the adhesive strength is reduced, a material that restores the adhesive strength by washing the adhesive surface 30a with water and rinsing the lint and the like and then drying is used.

  On one end of the adhesive member 30, a rotating shaft 31 extending in the left-right direction is provided. The adhesive member 30 is rotatably supported at a rear corner of the exhaust duct 13 around a rotation shaft 31. In addition, the exhaust duct 13 is provided with a motor 32 for moving the adhesive member 30 located at the rear corner. The rotation shaft of the moving motor 32 is connected to the rotation shaft 31 of the adhesive member 30.

  Thus, the adhesive member 30 sets the position of the posture that has fallen along the bottom wall 13a as the normal position (see FIG. 2), and the position of the standing posture as the contact position (see FIG. 3). By driving, it turns around the turning shaft 31 between the normal position and the contact position. That is, the adhesive member 30 retreats by moving to the normal position so that the adhesive surface 30a is separated from the lint capturing surface 20a of the filter member 20, as shown in FIG. On the other hand, the adhesive member 30 is applied so that the adhesive surface 30a contacts the lint capturing surface 20a of the filter member 20, as shown in FIG.

  As shown in FIGS. 2 and 3, the filter housing portion 25 and the exhaust duct 13 are disposed so as to be inclined at a predetermined angle α as a whole. For this reason, the bottom wall 13a of the exhaust duct 13 is an inclined surface inclined at a predetermined angle α with respect to the horizontal plane H. The angle α is such that water injected into the exhaust duct 13 from the nozzle portion 35 described below flows down the bottom wall 13a of the exhaust duct 13 or the adhesive member 30 at the normal position, and flows down to the front exhaust port 17. It is set so that the inclination becomes easy.

  Here, the water injection device 33 of this embodiment includes a water supply valve 8c in the water supply mechanism 8 shown in FIG. 1, a nozzle portion 35 above the exhaust duct 13 shown in FIG. 2, and a connection connecting the water supply valve 8c and the nozzle portion 35. Hose 34 is included. Among them, the water supply valve 8c is a water supply valve (referred to as “removal water supply valve 8c” as appropriate) separate from the main water supply valve 8b in the water supply mechanism 8. When the removal water supply valve 8c is opened, water from the water supply source is injected into the exhaust duct 13 from the nozzle portion 35 through the connection hose 34.

  As shown in FIG. 2, the nozzle portion 35 is disposed on the rear end side of the upper part of the duct 13 with the nozzle hole facing the inside of the exhaust duct 13. In addition, the nozzle portion 35 is configured such that water injected by injection from the nozzle hole (see the injection direction W1) hits the rear end side (base end side) of the adhesive surface 30a of the adhesive member 30 at the normal position, and the exhaust port 17 It is installed in a direction inclined to the direction of falling down to the side.

  Although not shown in detail, the nozzle portion 35 has a flat shape in which a tapered portion 36 that expands in the left-right direction toward the distal end side is formed in the nozzle hole. The water sprayed from the nozzle portion 35 in a fan shape by the tapered portion 36 spreads to both ends in the width direction of the adhesive member 30 at the normal position, and hits the rear end side of the adhesive surface 30a. The water flows from the rear end side to the front end side along the adhesive surface 30a by the above-described water injection direction W1 and the inclination angle α of the adhesive member 30, so that the entire adhesive surface 30a can be washed with water. Also, this water does not flow out to the intermediate duct 14 side due to a step between the bottom wall 13a of the exhaust duct 13 and the bottom wall 25a of the filter housing portion 25, and travels along the bottom wall 13a of the exhaust duct 13 to exhaust. It flows out of the mouth 17 into the water tank 7.

The adhesive member 30, the moving motor 32, and the water injection device 33 function as a removing device 37 for removing the lint captured by the filter member 20.
An operation signal from an input unit of the operation panel 5 and sensor signals from various sensors (not shown) are input to the control device 6. The control device 6 controls the display of the display unit of the operation panel 5, the drum motor 11, the water supply valves 8 b and 8 c, the drain valve 9 a, the compressor of the heat pump 18, the fan motor 21 b of the blower 21, and the adhesive member 30. Of the moving motor 32 and the like are controlled.

  Then, the control device 6 controls the motors 11 and 21b based on sensor signals from various sensors and a control program stored in a storage unit of the control device 6 according to a driving course set by a user on the operation panel 5. , 32 and the water supply valves 8b, 8c, etc., and automatically executes the washing operation including the well-known washing, rinsing, and dehydration processes and the drying operation.

  Next, the operation of the above configuration will be described focusing on the operation in the drying operation and the operation after the drying operation is completed. Here, it is assumed that the adhesive member 30 is normally at a normal position including the washing operation and the drying operation and is separated from the lint capturing surface 20a of the filter member 20 (see FIG. 2).

  When starting the drying operation, the control device 6 appropriately rotates the rotary tub 10 by the drum motor 11 and drives the compressor of the heat pump 18 and the fan motor 21b, respectively. By driving the compressor, heat is radiated from the condenser 19b and the surrounding air is cooled by the evaporator 19a. In addition, the warm air heated by the condenser 19 b in the circulation air passage 12 by the driving of the fan motor 21 b passes through the air supply duct 16, from the air supply port 23 to the inside of the water tank 7 (drying chamber), and thus to the inside of the rotary tank 10. (See arrow in FIG. 1). The warm air supplied into the rotating tub 10 contacts the clothing and warms the clothing, and removes moisture from the clothing.

  In this case, the air containing moisture is discharged from the exhaust port 17 to the exhaust duct 13 side of the circulation air passage 12. The air discharged to the exhaust duct 13 side enters the heat pump duct 15 from the filter housing portion 25 of the intermediate duct 14 through the duct 14. The air that has entered the heat pump duct 15 is cooled and dehumidified when passing through the evaporator 19a. The dehumidified air is heated again by the condenser 19b, and is supplied from the air supply port 23 into the water tank 7 and further into the rotary tank 10. By repeating this, the clothes in the rotating tub 10 are dried.

  During such a drying operation, lint such as lint from the clothes is also discharged from the exhaust port 17 to the exhaust duct 13 side. When the lint discharged to the exhaust duct 13 side passes through the filter member 20 of the filter housing portion 25, the lint is captured by the lint capturing surface 20a.

  After the drying operation is completed, the lint captured on the lint capturing surface 20a is removed by the removing device 37. Specifically, when the control device 6 determines that the clothes in the rotating tub 10 have been taken out based on the sensor signal of the opening / closing detection sensor that detects the opening / closing of the door 4 after the drying operation, the control unit 6 sets the adhesive member 30 to the normal state. The movement motor 32 is driven to move from the position to the contact position. Thereby, the adhesive member 30 rotates around the rotation shaft 31 in the direction of the arrow N1 in FIG. 2 and is applied to the filter member 20 in an upright posture at the contact position (see FIG. 3). At this time, the adhesive surface 30a of the adhesive member 30 is pressed against the lint capturing surface 20a to adhere the lint on the capturing surface 20a.

  Next, the control device 6 drives the movement motor 32 so as to move the adhesive member 30 from the contact position to the normal position. Thereby, the adhesive member 30 rotates in the direction of the arrow N2 and returns to the normal position while the lint is adhered and held by the adhesive force of the adhesive surface 30a. That is, as the adhesive member 30 moves to the normal position, the lint is peeled off and removed from the lint capturing surface 20a, and the adhesive member 30 assumes a posture in which it falls down along the bottom wall 13a (see FIG. 2).

  Thereafter, the control device 6 opens the removal water supply valve 8c, injects water from the nozzle portion 35, and performs water injection to hit the adhesive member 30 at the normal position. At this time, the water sprayed from the nozzle portion 35 spreads to both ends in the width direction of the adhesive surface 30a of the adhesive member 30, and hits the rear end side of the adhesive surface 30a. The water flows down the adhesive surface 30a from the rear end side to the front end side along the adhesive surface 30a, and reaches the entire adhesive surface 30a. At that time, the lint on the surface of the adhesive surface 30a is washed away (washed out), and exhausted. It flows out of the mouth 17 into the water tank 7. In FIG. 2, the lint R to be removed is schematically represented by a small triangular shape for convenience of explanation.

A series of operations in the removing device 37, including the injection of water from the nozzle portion 35 and the movement of the adhesive member 30, may be executed at a timing before the next washing operation is started.
That is, the series of operations in the removing device 37 may be performed at the timing when the clothes are taken out after the end of the drying operation as described above, or at the timing before the next washing operation in the next washing operation instead of the timing. The lint of the filter member 20 is removed by the adhesive surface 30 a of the adhesive member 30, and the adhesive surface 30 a can be washed away by water injection from the nozzle portion 35. When the drying operation is performed thereafter, the air circulating through the circulation air passage 12 accelerates the drying of the adhesive surface 30a during the drying operation, and the original adhesive force is restored if the drying is performed. Therefore, the lint of the filter member 20 can be repeatedly removed on the adhesive surface 30a of the adhesive member 30.

  As described above, the removal device 37 of the present embodiment includes the adhesive member 30 in the normal position where the adhesive surface 30a is retracted so that the adhesive surface 30a is separated from the lint capturing surface 20a of the filter member 20, and the adhesive surface 30a. The adhesive member 30 is configured to be movable between a contact position to which the adhesive member 30 is applied so as to contact the lint capturing surface 20a, and the adhesive surface 30a is made of a material capable of regenerating adhesive force by water injection. Is formed.

  According to this, since the adhesive member 30 retreats from the lint capturing surface 20a at the normal position, it does not hinder the capture of the lint by the filter member 20, and the lint on the lint capturing surface 20a at the contact position. By sticking, the lint on the capture surface 20a can be removed. In addition, since the original adhesive strength is restored by injecting water into the adhesive surface 30a, it is possible to prevent the filter member 20 from being clogged in the circulation air passage 12 without maintenance. Thereby, it is possible to prevent a decrease in the air volume in the circulation air passage 12, and to maintain the drying performance for a long period of time.

Further, the removing device 37 has a nozzle unit 35 that sprays water toward the adhesive surface 30a of the adhesive member 30 at the normal position. According to this, the cleaning effect of the adhesive surface 30a by water injection can be enhanced by using the injection of water from the nozzle portion 35, and a decrease in the adhesive force can be suppressed as much as possible.
The water injected after washing off the adhesive surface 30a flows out of the exhaust port 17 into the water tank 7, then bypasses the outer surface of the rotary tank 10, passes through the drain port 7b and the drain pipe 9 via the drain valve 9a, and then is discharged from the drain pipe 9 to the outside of the machine. Is discharged.

<Other embodiments>
4 to 8 show second to sixth embodiments of the present invention. Hereinafter, points that are substantially different from the above-described embodiment will be described. For convenience of description, in FIGS. 4 to 6 and 8, the adhesive member 30 at the normal position and the contact position is represented by a solid line and a two-dot chain line, and in FIG. 7, only the adhesive member 30 at the normal position is represented by a two-dot chain line. Represents.

  The water injection device 40 of the second embodiment shown in FIG. 4 differs from the water injection device 33 of the first embodiment in the following points. That is, the nozzle portion 41 of the water injection device 40 is a so-called diffusion type, and the nozzle hole is formed with a conical tapered portion 42 that expands in a C-shaped cross section toward the distal end side. The angle β of the tapered portion 42 shown in FIG. 3 is set such that water radially sprayed from the nozzle portion 41 toward the adhesive member 30 at the normal position hits the entire upper surface of the adhesive member 30.

  As described above, since the water injection device 40 of the second embodiment has the nozzle portion 41 that applies water to at least the entire surface of the adhesive surface 30a with respect to the adhesive member 30 at the normal position, the cleaning effect of the water injection on the adhesive surface 30a is achieved. Can be further increased.

  The nozzle part 51 of the water injection device 50 of the third embodiment shown in FIG. 5 has a wider water injection area than the nozzle part 41 of the second embodiment. Specifically, in the nozzle portion 51, the angle γ of the tapered portion 52 formed in the nozzle hole is set to be larger than the angle β (γ> β). For this reason, the water sprayed radially downward from the nozzle portion 51 is diffused and hits the entire upper surface of the adhesive member 30, and the bottom wall 13 a and the left and right side walls 13 c of the exhaust duct 13 and the front side wall 13 b (that is, the front side wall 13 b). A wide range of water injection, which also hits the wall 13b) farthest from the nozzle part 51, is provided. Therefore, even if lint is accumulated on the inner walls 13a to 13c of the exhaust duct 13 and the bellows portion 13z, the lint on the inner periphery of the portions 13a to 13c and 13z is adhered to the adhesive surface by the water from the nozzle portion 51. It can be washed away with the lint of 30a.

  As described above, the water injection device 50 of the third embodiment uses the adhesive surface 30a of the adhesive member 30 at the normal position as a part of the water injection area, and the adhesive surface 30a and the inner walls 13a to 13c of the exhaust duct 13; It is configured to perform water injection extending over 13z. According to this, not only the lint on the adhesive surface 30a but also the lint on the inner walls 13a to 13c and 13z of the exhaust duct 13 can be washed away. As a result, a decrease in the air volume of the circulation air passage 12 can be suppressed as much as possible, and the sanitary aspect of the circulation air passage 12 can be improved.

The water injection device 60 of the fourth embodiment shown in FIG. 6 includes the same nozzle section 35 as in the first embodiment, and a motor 61 for moving the nozzle 35.
The nozzle portion 35 is provided with a support shaft 35 a that is swingably supported on the upper surface side of the exhaust duct 13. The moving motor 61 is arranged on the upper surface side of the exhaust duct 13, and the rotation shaft of the motor 61 is connected to the support shaft 35 a of the nozzle unit 35. When water is injected into the adhesive member 30, the control device 6 controls the rear end position (see the injection direction W <b> 1) where the jetted water hits the rear end side of the adhesive surface 30 a and the front end of the exhaust duct 13. The movement motor 61 is controlled so that the nozzle portion 35 repeatedly swings between a front end position (refer to the ejection direction W3) which hits the wall 13b.

  In this manner, the nozzle portion 35 swings between the rear end position and the front end position, so that the water jetted from the nozzle portion 35 moves from the rear end side to the front end side (from the jetting direction W1) of the adhesive member 30. W2) and hits the front wall 13b from the front end side to the front wall 13b (injection directions W2 to W3), and extends from the range of W1 to W3. In this case, needless to say, the nozzle portion 35 may be a wider taper portion 36 so that the water also hits the left and right side walls 13c of the exhaust duct 13.

  As described above, in the water injection device 60 of the fourth embodiment, since the nozzle portion 35 is configured to be able to swing with respect to the adhesive surface 30a, the nozzle portion 35 is not the diffusion type. The area where water is directly applied to the adhesive surface 30a can be further widened while spraying water that can be squeezed and flushed vigorously, thereby improving the cleaning effect.

In addition, the nozzle portion 35 is attached in such a manner that the water sprayed from the nozzle hole hits the left end side (base end side) of the adhesive surface 30a of the adhesive member 30 at the normal position, and is inclined in a direction of flowing down to the right side. I have. Therefore, the water sprayed from the nozzle portion 35 hits the left end of the adhesive surface 30a and flows from the left end to the right end, thereby washing the entire adhesive surface 30a. Further, the water flowing to the right side of the adhesive surface 30a flows toward the rear corner where the third hole 73 exists as shown by the arrow W4 in FIG. It is discharged outside the machine through the pipes 75 and 9.

  As described above, in the configuration of the fifth embodiment, as the drainage path 76 for draining the water provided for the regeneration of the adhesive force of the adhesive surface 30a by injecting the water from the nozzle portion 35 to the outside of the water tank 7, An inclined surface 70 a of the duct 70, a third hole 73, and drain pipes 75 and 9 are provided. According to this, it is possible to prevent water containing lint from flowing into the water tank 7 after washing away the adhesive surface 30a and the like, and to eliminate a situation in which the lint adheres to clothing in the water tank 7. it can. In addition, the drainage path 76 may be configured by a concave groove (not shown) formed on the bottom wall of the duct 70 so as to directly communicate with the third hole 73 instead of the inclined surface 70 a of the duct 70. Such a groove can also be used as a drainage path that bypasses the water tank 7 to the second hole 72.

The filter housing part 80 and the exhaust duct 81 of the sixth embodiment shown in FIG. 8 are different from the filter housing part 25 and the exhaust duct 13 of the first embodiment in the following points.
That is, the filter housing portion 80 and the exhaust duct 81 are disposed so as to extend horizontally as a whole immediately below the upper surface portion 2b of the outer box 2. The exhaust duct 81 is provided with a bottom wall 81a (inclined surface) inclined at the predetermined angle α in order to allow water used for regeneration of the adhesive force of the adhesive surface 30a to flow toward the exhaust port 17 side. The nozzle part 35 indicated by a broken line in FIG. 8 is arranged so as to penetrate the upper part of the side wall 13c of the exhaust duct 81, and performs the same water injection as in the first embodiment (see the injection direction W1).

  An opening 81b is formed at a position corresponding to the adhesive member 30 on the upper surface of the exhaust duct 81, and a lid 82 closing the opening 81b is provided. In FIG. 8, the lid 82 is shown to be openable and closable around the support shaft 82a, but the lid 82 is locked at the upper surface 2b of the outer box 2 or the upper surface of the exhaust duct 81. Accordingly, the opening 81b is always closed. Then, the lid 82 is opened by a user or a serviceman, and the adhesive member 30 can be attached and detached.
