Summary of the invention

The problem to be solved by the invention

In the integrated washer-dryer described in Patent Document 1, since the user needs to periodically remove the drying filter for cleaning, the maintenance of the drying filter is laborious. In particular, in the existing washer-dryer, the drying filter needs to be cleaned after each drying process, so the number of times to remove the drying filter increases. When the number of times of removing the drying filter increases, the possibility of the user damaging the drying filter when removing or assembling the drying filter increases.

The present invention is an invention completed under such a background, and its purpose is to provide a washer-dryer integrated machine that can improve the maintainability of the drying filter.

Solution to the problem

The present invention is a washing-drying integrated machine, comprising: a box body; an outer tube supported by the box body and capable of storing water; a washing tube contained in the outer tube and containing washing; a circulation path with The outlet and return port connected to the outer cylinder; an air blowing part that takes out the air in the outer cylinder from the outlet to the circulation path and returns from the return port to the outer cylinder To make it circulate; a heating part is provided in the circulation path to heat the air in the circulation path; a drying filter is arranged in the circulation path closer to the outlet side than the heating part, And has a vertical surface portion that captures foreign matter in the air from the outlet to the return port in the circulation path; a water supply unit that supplies water to the vertical surface portion from the upper side; and a scraper that can move along the vertical surface The face moves; and the actuator moves the scraper.

In addition, the present invention is characterized in that the washer-dryer further includes: a control unit that controls the water supply unit and the actuator, and the control unit moves the scraper to The lower part of the vertical surface part is supplied with water from the upper side to the vertical surface part through the water supply part for maintenance processing.

In addition, the present invention is characterized in that the integrated washer-dryer further includes: a pipe for accommodating the drying filter as a part of the circulation path, and a release hole is formed on the lower side of the vertical surface; a drainage path , For draining the water in the outer cylinder; and a flow path connecting the release hole and the drain path.

Invention effect

According to the present invention, the air in the outer cylinder of the integrated washer-dryer circulates so as to be taken out from the outlet to the circulation path and returned to the outer cylinder from the return port. The circulating air is heated by the heating part in the circulation path to become hot air, and the laundry in the washing tub is dried. The drying filter provided in the circulation path on the side of the outlet port rather than the heating unit captures foreign matter contained in the air from the outlet port to the return port in the circulation path for circulation in the vertical surface portion. Therefore, it is possible to prevent foreign matter in the air from adhering to the heating part.

When the water supply part supplies water to the vertical surface portion of the drying filter from the upper side, the foreign matter captured and attached to the vertical surface portion is peeled from the vertical surface portion by the water flowing through the vertical surface portion. The foreign matter adhering to the vertical surface is also scraped off from the vertical surface by being scraped by the scraper moving along the vertical surface. For example, the foreign matter peeled from the vertical surface falls into the circulation path and reaches the outer cylinder from the outlet, and is removed from the outer cylinder when the outer cylinder is drained. In this way, the washer-dryer has an automatic cleaning function of the drying filter realized by water and a scraper, so the user can maintain the drying filter without removing the drying filter. Therefore, the maintenance of the drying filter can be improved.

In addition, according to the present invention, it is assumed that the scraper scrapes foreign matter from the longitudinal surface of the drying filter, and the foreign matter adheres to the wiper. In this case, the wiper moves to the lower part of the longitudinal surface. Water is supplied from the upper side to the vertical surface for maintenance. Thereby, foreign matter adhering to the wiper can be removed from the wiper by the water flowing through the vertical surface portion. Therefore, the user does not need to maintain the drying filter or the scraper. Therefore, the maintainability can be improved.

In addition, according to the present invention, the water supplied from the water supply part and the foreign matter removed from the vertical surface of the drying filter can flow from the discharge hole of the pipe and the flow path to the drain path without passing through the outer cylinder. Thereby, it is possible to prevent water and foreign matter from adhering to the laundry contained in the washing tub of the outer tub.

In the vertical direction Z, the upper side is referred to as the upper side Z1, and the lower side is referred to as the lower side Z2.

The washer-dryer 1 is a so-called drum washer-dryer. The washer-dryer 1 includes: a box body 2, an outer tube 3 arranged in the box body 2, a water supply channel 4 and a drain channel 5 connected to the outer tube 3, and capture from the water discharged from the outer tube 3 through the drain channel 5 Drain filter for foreign matter 6. The washer-dryer 1 further includes: a washing tub 7 housed in the outer tub 3 and accommodating laundry L; a motor 8 to rotate the washing tub 7; and a drying unit 9 to dry the laundry L in the washing tub 7.

The box 2 is formed in a box shape. The front surface 2A of the box 2 is, for example, a vertical surface. On the front surface 2A, an opening 2B for communicating the inside and outside of the box 2 is formed. The front surface 2A is provided with a door 10 that opens and closes the opening 2B.

The outer cylinder 3 is elastically supported by the box 2 via a hanging rod (not shown). The outer cylinder 3 has a cylindrical circumferential wall 3A centered on an axis J extending in the front and rear direction Y along the horizontal direction H, a disc-shaped back wall 3B that blocks the hollow portion of the circumferential wall 3A from the rear side Y2, and An annular front wall 3C connected to the front end edge of the circumferential wall 3A. The back wall 3B is arranged vertically, and has an outer peripheral portion 3D and a central portion 3E that protrudes one step further to the rear side Y2 than the outer peripheral portion 3D. In the center of the central portion 3E, a through hole 3F that penetrates the central portion 3E in the front-rear direction Y along the axis J is formed. The front wall 3C has an annular first portion 3G protruding from the front end edge of the circumferential wall 3A to the axis J side, a cylindrical second portion 3H protruding from the inner peripheral edge of the first portion 3G to the front side Y1, and The annular third portion 3I protrudes from the front end edge of the second portion 3H to the axis J side. On the inner side of the third portion 3I, an inlet and outlet 3J communicating with the hollow portion of the circumferential wall 3A from the front side Y1 is formed. The entrance 3J faces and communicates with the opening 2B of the box 2 from the rear side Y2.

The water supply channel 4 has one end (not shown) connected to a faucet (not shown) and the other end 4A connected to, for example, the central portion 3E of the back wall 3B of the outer tube 3. At the time of water supply, water from the faucet is supplied from the water supply path 4 into the outer cylinder 3. The outer cylinder 3 stores water such as tap water and detergent water in which detergent is dissolved in the tap water. In the middle of the water supply path 4, a water supply valve 11 that is opened and closed in order to start or stop water supply is provided.

The drainage channel 5 is connected to the lower end of the outer cylinder 3, for example, the lower end of the first part 3G of the front wall 3C. The water in the outer cylinder 3 is drained from the drain 5 to the outside of the fuselage. In the middle of the drain path 5, a drain valve 12 that is opened and closed to start or stop draining is provided.

The drain filter 6 is provided in the drain path 5 closer to the upstream portion of the outer cylinder 3 than the drain valve 12. Since the front end of the drain filter 6 is exposed to the front surface 2A of the box body 2, the user can grasp the front end of the drain filter 6 to detach the drain filter 6 to the box body 2. The structure of the drainage filter 6 can use a well-known structure.

The washing tub 7 is one circle smaller than the outer tub 3. The washing tub 7 has a cylindrical circumferential wall 7A arranged coaxially with the circumferential wall 3A of the outer tub 3, a disc-shaped back wall 7B that blocks the hollow portion of the circumferential wall 7A from the rear side Y2, and An annular wall 7C in which the front end edge of the wall 7A protrudes to the axis J side. In the washing tub, a plurality of through holes 7D are formed at least in the circumferential wall 7A, and the water in the outer tub 3 flows between the outer tub 3 and the washing tub 7 through the through holes 7D. Thus, the water level in the outer tub 3 and the water level in the washing tub 7 coincide. At the center of the back wall 7B of the washing tub 7, a support shaft 13 extending along the axis J to the rear side Y2 is provided. The rear end of the support shaft 13 passes through the through hole 3F of the back wall 3B of the outer cylinder 3 and is arranged on the back side Y2 of the back wall 3B.

On the inner side of the annular wall 7C, an inlet and outlet 7E communicating with the hollow portion of the circumferential wall 7A from the front side Y1 is formed. The port 7E faces and communicates with the port 3J of the outer cylinder 3 and the opening 2B of the box 2 from the rear side Y2. The entrance 3J and the entrance 7E are opened and closed together with the opening 2B by the door 10. The user of the washer-dryer 1 throws the laundry L into the washing tub 7 through the open opening 2B, the entrance 3J, and the entrance 7E.

The motor 8 is arranged on the rear side Y2 of the back wall 3B of the outer cylinder 3 in the housing 2. The motor 8 is connected to a support shaft 13 provided in the washing tub 7. The driving force generated by the motor 8 is transmitted to the support shaft 13, and the washing tub 7 rotates around the axis J along with the support shaft 13. It should be noted that a clutch mechanism (not shown) that transmits or cuts off the driving force of the motor 8 to the support shaft 13 may be provided between the motor 8 and the support shaft 13.

The drying unit 9 includes a circulation path 20, an air blowing part 21, and a heating part 22. The circulation path 20 is a flow path arranged on the upper side Z1 of the outer cylinder 3 in the tank 2. The circulation path 20 has a midway portion 20A extending in the front-rear direction Y, a rear portion 20B extending from the rear end of the midway portion 20A to the lower side Z2, and a front portion 20C extending from the front end of the midway portion 20A to the lower side Z2. A take-out port 20D is formed at the front end of the lower end of the rear portion 20B. The take-out port 20D is connected to a part of the outer peripheral portion 3D of the back wall 3B of the outer cylinder 3 that is higher than the upper limit water level, and communicates with the inner cylinder 3 from the rear side Y2. A return port 20E is formed at the lower end of the front portion 20C. The return port 20E is connected to the upper end of the second part 3H of the front wall 3C of the outer cylinder 3 and communicates with the inner cylinder 3 from the upper side Z1.

The air blowing section 21 is a so-called blower, and includes a rotating blade 23 arranged in an area close to the upstream side of the outlet 20D in the circulation path 20, and a motor (not shown) that rotates the rotating blade 23. When the rotating blade 23 rotates, the air in the outer tub 3, that is, the air in the outer tub 3 and the washing tub 7, as shown by the thick dotted arrow, is taken out from the outlet 20D into the circulation path 20, and then from the return port 20E returns to the outer cylinder 3. Thereby, the air in the outer cylinder 3 circulates so as to flow through the outer cylinder 3 and the circulation path 20 in order.

The heating unit 22 is a heat exchanger in a heat pump, a general heater, or the like, and is provided at least partially in the circulation path 20. A part of the heating part 22 provided in the circulation path 20 has a plurality of fin-shaped heat dissipation parts 22A. Since the heat dissipating part 22A becomes high temperature when the heating part 22 is operated, the air flowing in the circulation path 20 is heated to become hot air when passing around the heat dissipating part 22A.

The washer-dryer 1 further includes a control unit 24 configured as a microcomputer. The control unit 24 performs washing and drying operations by controlling the actions of the motor 8, the water supply valve 11, the drain valve 12, the air blowing unit 21, and the heating unit 22. The washing and drying operation includes a washing process, a rinsing process, a dehydration process, and a drying process.

Before the washing process starts, detergent is put into the washing tub 7. During the washing process, with the drain valve 12 closed, the control unit 24 opens the water supply valve 11 for a predetermined time to supply water to the outer tub 3 and the washing tub 7, and then the motor 8 rotates the washing tub 7. As a result, the laundry L in the washing tub 7 is knocked. During knock washing, the laundry L is repeatedly lifted to a certain extent and then naturally falls to the water surface by "rolling". The impact caused by the tumbling and the detergent components contained in the detergent water stored in the washing tub 7 remove dirt from the laundry L. When the control unit 24 opens the drain valve 12 to drain water after a predetermined time has elapsed since the start of tumbling, the washing process ends.

During the rinsing process, with the drain valve 12 closed, the control unit 24 opens the water supply valve 11 for a predetermined time to supply water to the outer tub 3 and the washing tub 7, and then the motor 8 rotates the washing tub 7. In this way, since the above-mentioned tumbling is repeated, the laundry L is rinsed by the tap water in the washing tub 7. The rinsing process ends when the control unit 24 performs drainage after a predetermined time has elapsed since the start of tumbling. The rinsing process can be repeated many times. During the spin-drying process, the control unit 24 spins the washing tub 7 while the drain valve 12 is opened. The laundry L in the washing tub 7 is dehydrated by the centrifugal force generated by the dehydration rotation of the washing tub 7. The water seeping out from the laundry L by the dehydration is discharged from the drain 5 to the outside of the machine. The dehydration process is not only implemented after the rinsing process, but can also be implemented after the washing process.

During the drying process, the control unit 24 generates hot air through the air blowing unit 21 and the heating unit 22 and circulates it between the washing tub 7 and the circulation path 20 to supply the laundry L in the washing tub 7. Thus, the laundry L is dried. During the washing operation, foreign matter such as thread shreds is generated, and the foreign matter flows with the hot air during the drying process. When foreign matter adheres to and accumulates on the heat radiating portion 22A of the heating section 22, it may cause performance degradation due to a decrease in the heating efficiency of the heating section 22 and deterioration of the air flow in the circulation path 20, so the foreign matter needs to be captured. Therefore, the drying unit 9 further includes: a filter member 25, a branch 26, and a water injection valve 27.

Hereinafter, after the blower 21 and the circulation path 20 are described in detail, the filter member 25, the branch path 26, and the water injection valve 27 will be described. Fig. 2 is a perspective view of the outer cylinder 3 and the drying unit 9 viewed from the rear side Y2. The blower 21 includes a hollow disk-shaped housing 29 in which the rotating blades 23 are housed. The housing 29 is a part of the circulation path 20 and is fixed to the box 2. The internal space of the housing 29 constitutes a connection portion between the midway portion 20A and the rear portion 20B in the circulation path 20.

FIG. 3 is an exploded perspective view of the outer cylinder 3 and the drying unit 9. The circulation path 20 includes a pipe 30 that occupies almost the entire rear portion 20B, and a connecting hose 31 connecting the housing 29 and the pipe 30. The duct 30 includes a main body 32 and a cover 33 (refer to FIG. 2).

The top wall 32B extends obliquely with respect to the horizontal direction H so as to descend more toward the left side X2. The top wall 32B is provided with a cylindrical upper connecting portion 32D protruding to the upper side Z1. The internal space of the upper connecting portion 32D is in a state of communicating with the downstream space 32C from the upper side Z1. The downstream space 32C and the internal space of the upper connecting portion 32D constitute a part of the internal space of the rear part 20B of the circulation path 20. The main body 32 has a side wall 32E installed between the ends of the curved wall 32A and the top wall 32B so as to block the downstream space 32C from the front side Y1 and the left side X2.

The main body 32 has a first vertical wall 32F extending from the rear end of the curved wall 32A to the lower side Z2, and a lateral wall 32G protruding from the lower end of the first vertical wall 32F to the rear side Y2. The upper end of the first vertical wall 32F is curved in an arc shape along the curved wall 32A, and the lower end of the first vertical wall 32F extends linearly while being inclined with respect to the horizontal direction H so as to descend toward the left side X2. The horizontal wall 32G has a belt shape, and extends while being inclined with respect to the horizontal direction H along the lower end of the first vertical wall 32F. The rear end of the side wall 32E is arranged on the rear side Y2 of the downstream space 32C, and the lower part of the rear end of the side wall 32E is connected to the left ends of the first vertical wall 32F and the lateral wall 32G.

The main body 32 has an L-shaped second vertical wall 32H when viewed from the rear end of the side wall 32E and the back side of the lateral wall 32G. At the lower end of the second vertical wall 32H, a single or a plurality of the above-mentioned outlets 20D are formed. In the present embodiment, one elongated hole-shaped extraction port 20D is formed in the vertical direction Z, and penetrates the second vertical wall 32H in the front-rear direction Y. The second vertical wall 32H is provided with a cylindrical lower connecting portion 32I that surrounds the take-out port 20D and protrudes to the front side Y1. The outer peripheral part 3D of the back wall 3B of the outer cylinder 3 is formed with a through hole 3K having the same shape as the outlet 20D. The lower connecting portion 32I is inserted into the through hole 3K from the rear side Y2. Thereby, the take-out port 20D is connected to the back wall 3B and communicates with the inside of the outer cylinder 3.

The main body 32 has an outer wall 32J that continuously surrounds the right edge of the first vertical wall 32F and the left edge, lower edge, and right edge of the second vertical wall 32H and protrudes toward the rear side Y2. The outer wall 32J is formed in a substantially U-shape when viewed from the back, and the two upper ends of the outer wall 32J are respectively connected to the left end and the right end of the rear end of the top wall 32B. In the upper end of the outer wall 32J connected to the right end of the top wall 32B, a notch 32JA recessed to the front side Y1 is formed. In the front area on the outer peripheral surface of the outer wall 32J, a plurality of first locking portions 32JB protruding from the outer peripheral surface are provided. The bolt B1 (refer to FIG. 2) is inserted through the insertion hole formed in each first locking portion 32JB, and is attached to the screw hole 3L provided at the corresponding position of the back wall 3B of the outer cylinder 3. Thus, the duct 30 including the main body 32 is integrally fixed to the outer cylinder 3. The main body 32 is formed with a midway space 32K partitioned by the rear end of the side wall 32E, the lateral wall 32G, the top wall 32B, and the right part of the outer wall 32J. The midway space 32K has a substantially rectangular shape when viewed from the back, and is a thin space in the front-rear direction Y. It is adjacent to the first vertical wall 32F from the rear side Y2 and communicates with the downstream space 32C from the rear side Y2.

The main body 32 has a vertical partition plate 32L and a horizontal partition plate 32M protruding from the second vertical wall 32H to the rear side Y2. The vertical partition plate 32L is arranged adjacent to the midway space 32K from the left side X2, extends from the rear end of the top wall 32B to the lower side Z2, and is connected to the edge of the upper side Z1 of the outlet 20D. The horizontal partition plate 32M is arranged on the lower side Z2 of the midway space 32K and on the upper side Z1 of the take-out port 20D, and is installed between the midway portion of the vertical partition plate 32L and the right portion of the outer wall 32J. The horizontal partition plate 32M is inclined with respect to the horizontal direction H so as to be lowered toward the left side X2, while extending substantially parallel to the top wall 32B and the horizontal wall 32G. In the middle of the horizontal partition plate 32M, a slit 32P that divides the horizontal partition plate 32M into two in the left-right direction X is formed. A screw hole 32Q is formed in the rear surface portion of the second vertical wall 32H in the slit 32P.

The main body 32 is formed with an arrangement space 32R partitioned by the right part of the vertical partition plate 32L, the horizontal partition plate 32M, the top wall 32B, and the outer wall 32J. The arrangement space 32R has a substantially rectangular shape when viewed from the back, is a thin space in the front-rear direction Y, and communicates with the midway space 32K from the rear side Y2. In the arrangement space 32R, the part located on the upper side Z1 of the horizontal wall 32G overlaps the entire area of the halfway space 32K when viewed from the back. The filter member 25 is arranged in the arrangement space 32R. The main body 32 is formed with an upstream space 32S partitioned by a portion of the vertical partition plate 32L located on the lower side Z2 of the horizontal partition plate 32M, the horizontal partition plate 32M, and the right and lower parts of the outer wall 32J. The upstream space 32S is a substantially semicircular space that bulges to the lower side Z2 when viewed from the back, is located on the lower side Z2 of the arrangement space 32R via the horizontal partition plate 32M, and communicates with the outlet 20D from the rear side Y2.

The main body 32 is formed with a longitudinal space 32T which is sandwiched from both sides in the left-right direction X by the left part of the outer wall 32J and the vertical partition plate 32L and extends elongated in the vertical direction Z. The vertical space 32T is blocked from the front side Y1 by the left end of the second vertical wall 32H, and blocked from the upper side Z1 by the left end of the top wall 32B. The lower end of the vertical space 32T communicates with the upstream space 32S from the left side X2.

The cover 33 (refer to FIG. 2) has a wheel shape substantially identical to the outer wall 32J and the top wall 32B of the main body 32 when viewed from the back, and is formed in a plate shape whose width becomes narrower toward the lower side Z2. The cover 33 is provided with a plurality of locking portions 33A (refer to FIG. 2) protruding from the outer edge thereof. Corresponding to the locking portion 33A, a plurality of second locking portions 32JC protruding from the outer circumferential surface of the outer wall 32J of the main body 32 are provided in a rear area. A bolt (not shown) is inserted through an insertion hole formed in each locking portion 33A, and is attached to a screw hole 32JD provided on the rear end surface of the corresponding second locking portion 32JC. Thereby, the cover 33 is fixed to the main body 32 from the rear side Y2, and the duct 30 is completed (refer FIG. 2).

In the completed duct 30, the arrangement space 32R, the upstream space 32S, and the vertical space 32T provided on the rear surface side of the main body 32 are blocked by the cover 33 from the rear side Y2. The rear end of the vertical partition plate 32L is in contact with the front surface of the cover 33. Therefore, the arrangement space 32R and the vertical space 32T arranged with the vertical partition plate 32L interposed therebetween are partitioned. There is a gap Q (refer to FIG. 4) between the rear end of the horizontal partition plate 32M and the front surface portion of the cover 33, and therefore, the arrangement space 32R and the upstream space 32S communicate via the gap Q.

The connection hose 31 is, for example, a rubber cylinder, and its internal space is open to the upper side Z1 and the lower side Z2. Between the upper end and the lower end of the connection hose 31, a bellows 31A is provided. The lower end of the connecting hose 31 is externally fitted to the upper connecting portion 32D of the pipe 30. The upper end of the connection hose 31 is connected to the housing 29 of the blower 21. The internal space of the connection hose 31 constitutes a part of the internal space of the rear part 20B of the circulation path 20. Due to the elastic deformation of the bellows 31A, the transmission of the vibration of the outer tube 3 to the blower 21 during the washing and drying operation is suppressed.

The filter member 25 is formed in a thin plate shape in the front-rear direction Y. When viewed from the back, the overall shape of the filter member 25 is formed to have two sides inclined with respect to the horizontal direction H in such a way that the more it goes to the left X2, the more it descends, and the other two sides that extend substantially perpendicularly in the vertical direction Z. The rectangle is specifically formed as a parallelogram.

The filter member 25 includes a frame 41, a drying filter 42, and a water supply cover 43. The frame 41 has a main body 41A with a substantially rectangular wheel when viewed from the back; a pair of left and right vertical walls 41B protruding from the main body 41A to the front side Y1; and a bottom wall 41C from the lower end of the main body 41A to the front side Y1 Protruding, the frame 41 is made of resin, for example. The upper edge and the lower edge of the main body portion 41A are inclined with respect to the horizontal direction H so as to descend toward the left side X2. The right and left edges of the main body portion 41A extend substantially perpendicularly in the up-down direction Z. Almost the entire area of the main body 41A when viewed from the back is provided with an opening 41D penetrating the main body 41A in the front-rear direction Y. The main body 41A has a single or a plurality of longitudinal ribs 41E that longitudinally cut the opening 41D. In the present embodiment, two longitudinal ribs 41E are arranged side by side in the left-right direction X, and the opening 41D is equally divided by these longitudinal ribs 41E into three small openings 41DA arranged in the left-right direction X. Each small opening 41DA is formed in a longitudinally long rectangle, and strictly speaking, is formed in a parallelogram having two sides parallel to the upper and lower edges of the main body portion 41A.

The bottom wall 41C of the main body portion 41A spans between the lower ends of the left and right vertical walls 41B, and is inclined with respect to the horizontal direction H along the lower edge of the main body portion 41A so as to descend toward the left side X2. A locking portion 41CA protruding from the bottom wall 41C to the lower side Z2 is provided in the center portion of the bottom wall 41C in the left-right direction X. The locking portion 41CA is formed with an insertion hole 41CB penetrating the locking portion 41CA in the front-rear direction Y.

FIG. 4 is a perspective view of the duct 30 and the filter member 25 viewed from the rear side Y2. In FIG. 4, the illustration of the cover 33 of the duct 30 is abbreviate|omitted (it is the same also in FIG. 5 and FIG. 6 mentioned later). The frame 41 also has a top wall 41F protruding from the upper edge of the main body portion 41A to at least the rear side Y2. The top wall 41F has a main body portion 41FA that is in the shape of a rectangular plate long in the left-right direction X and is arranged obliquely to the lower left along the upper edge of the main body portion 41A; and an extension portion 41FB that is a rectangular plate shape shorter than the main body portion 41FA It extends from the right end of the main body 41BA to the right side X1 in the horizontal direction H. A plurality of water supply ports 41G having the same shape and the same size are formed in the main body portion 41FA. In this embodiment, 12 water supply ports 41G are provided. Each water supply port 41G extends linearly in the longitudinal direction, that is, the vertical direction Z, and penetrates the main body portion 41FA. These water supply ports 41G are arranged in a row at equal intervals in the left-right direction X along the upper end of the rear surface 41AB of the main body portion 41A.

The drying filter 42 is in a state of covering the entire area of each small opening 41DA of the main body portion 41A. Although the drying filter 42 is divided into three settings corresponding to each small opening 41DA, in this embodiment, the three separated drying filters 42 are regarded as one drying filter 42. Although the drying filter 42 in this embodiment is a mesh sheet fitted to the main body 41A, it may be a grid integrally formed with the main body 41A. In addition, although the drying filter 42 is made of metal in this embodiment, it may be made of resin like the main body 41A. The rear surface portion of the drying filter 42 that extends up, down, left and right is referred to as a vertical surface portion 42A. The vertical surface portion 42A of the drying filter 42 is arranged in the same plane as the rear surface 41AB of the main body portion 41A. The plurality of water supply ports 41G provided on the top wall 41F of the frame 41 are arranged along the vertical surface portion 42A of the drying filter 42 in the lateral direction, that is, in the left-right direction X, and face the vertical surface portion 42A from the upper side Z1.

The water supply cover 43 has a main body part 43A that is long and hollow in the left-right direction X, and a hollow connection part 43B connected to the main body part 43A from the right side X1. The internal space 43AA of the main body portion 43A and the internal space 43BA of the connecting portion 43B are in a communicating state. The connecting portion 43B is provided with a tubular pipe portion 43C protruding from the connecting portion 43B. Although the tube part 43C protruding to the rear side Y2 is shown in FIG. 4, the tube part 43C may also protrude to the right side X1 (refer to FIG. 5). The internal space 43CA of the pipe portion 43C communicates with the internal space 43BA of the connecting portion 43B. The internal space 43AA of the main body portion 43A, the internal space 43BA of the connection portion 43B, and the internal space 43CA of the pipe portion 43C are integrated to constitute a flow path 43D in the water supply cover 43. In addition, 43 C of pipe parts may not be provided in the connection part 43B of the water supply cover 43, but may be provided in the extension part 41FB (refer FIG. 5) of the top wall 41F of the frame 41, for example.

The water supply cover 43 covers the top wall 41F of the frame 41 from the upper side Z1 and is combined with the frame 41. In the filter member 25 completed in this way, the internal space 43AA of the main body 43A of the water supply cover 43 is blocked from the lower side Z2 by the main body 41FA of the top wall 41F, and the internal space 43BA of the connection part 43B of the water supply cover 43 is blocked by The extended portion 41FB of the top wall 41F is blocked from the lower side Z2. The flow path 43D in the water supply cover 43 is connected to all the water supply ports 41G formed in the top wall 41F from the upper side Z1. The top wall 41F and the water supply cover 43 covering the top wall 41F from the upper side Z1 constitute the water supply unit 50.

As shown in FIG. 4, the filter member 25 is accommodated in the duct 30 by fitting into the arrangement space 32R of the duct 30 from the back side Y2. The bottom wall 41C of the frame 41 of the filter member 25 is carried by the horizontal partition plate 32M of the duct 30, whereby the filter member 25 is positioned in the arrangement space 32R. The locking portion 41CA of the bottom wall 41C is fitted into the slit 32P of the horizontal partition plate 32M, and the bolt B2 is inserted into the threaded hole 32Q of the slit 32P through the insertion hole 41CB of the locking portion 41CA (see also FIG. 3). Thereby, the filter member 25 in the arrangement space 32R is fixed to the duct 30. It should be noted that the locking portion 41CA may also be provided at a position other than the bottom wall 41C in the frame 41.

In the frame 41 of the filter member 25 fixed to the duct 30, the bottom wall 41C, the right vertical wall 41B, and the left vertical wall 41B are in contact with the horizontal partition plate 32M, the outer wall 32J, and the vertical partition plate 32L of the duct 30, respectively. In addition, the main body portion 43A of the water supply cover 43 of the filter member 25 is in contact with the top wall 32B of the pipe 30. Thereby, the filter member 25 occupies almost the entire area of the arrangement space 32R of the duct 30, and is located between the downstream space 32C and the intermediate space 32K and the upstream space 32S in the duct 30. When the entire circulation path 20 is observed, the drying filter 42 in the filter member 25 is arranged in the circulation path 20 closer to the outlet 20D than the heating unit 22 (see FIG. 1). The extension part 41FB of the top wall 41F of the frame 41 and the connection part 43B of the water supply cover 43 pass through the cutout 32JA (refer to FIG. 3) of the outer wall 32J, and are arrange|positioned at the right side X1 of the arrangement space 32R.

The branch path 26 is branched from the upstream portion of the water supply path 4 closer to the faucet than the water supply valve 11, and is connected to the pipe portion 43C of the water supply cover 43. The water injection valve 27 is provided in the branch 26 (refer to FIG. 1). The water injection valve 27 is opened and closed in order to supply the water flowing from the water supply channel 4 to the branch 26 to the pipe portion 43C or to stop the supply. The opening and closing of the water injection valve 27 is controlled by the control unit 24 (refer to FIG. 1). The water injection valve 27 is included in the water supply unit 50 described above.

During the drying process, as described above, hot air is generated and circulated by the air blowing section 21 and the heating section 22. The hot air travels from the take-out port 20D to the return port 20E in the circulation path 20, and proceeds to the blower 21 while rising at the rear part 20B in the middle (refer to the thick broken line arrow in FIG. 1). In the duct 30 constituting the rear portion 20B, the hot air rises from the outlet 20D via the upstream space 32S, and passes through the drying filter 42 of the filter member 25 on the front side Y1. Then, the hot air reaches the downstream space 32C via the midway space 32K, rises inside the connecting hose 31, and flows into the housing 29 of the air blower 21 (also refer to FIG. 2).

The vertical surface part 42A of the drying filter 42 is arranged so as to face the upstream side of the circulation path 20, and foreign matter T such as broken thread is captured from the hot air in the circulation path 20. As the drying process progresses, a large amount of foreign matter T is captured and left on the longitudinal surface 42A. As a result, it is possible to prevent the foreign matter T from adhering to the heating unit 22 that is provided to be shifted downstream from the outlet 20D than the drying filter 42 in the circulation path 20.

After the drying process, that is, after the washing and drying operation ends, the control unit 24 opens the water injection valve 27. It should be noted that the water supply valve 11 may be provided in the water supply path 4 closer to the upstream side of the faucet than the branch position of the branch path 26. In this case, the control unit 24 opens both the water supply valve 11 and the water injection valve 27. The water from the faucet passes through the water supply path 4 and the branch path 26, and flows from the pipe portion 43C of the water supply cover 43 into the flow path 43D.

The water flowing into the flow path 43D flows out from the flow path 43D to each water supply port 41G and is sprayed downward from each water supply port 41G. The water sprayed from each water supply port 41G, as indicated by the thick dotted arrow, showers from the upper side Z1 to the upper end of the vertical surface portion 42A of the drying filter 42 and flows down through the vertical surface portion 42A. The foreign matter T adhering to the vertical surface portion 42A is peeled off from the vertical surface portion 42A by the water flowing through the vertical surface portion 42A, directly falls into the upstream space 32S of the duct 30, and reaches the extraction port 20D. A longitudinal rib 41E extending in the direction in which water and foreign matter T fall is provided around the drying filter 42. Therefore, the foreign matter T does not hang on the longitudinal rib 41E and falls smoothly. In the duct 30, the guide part 30A inclined toward the take-out port 20D is provided in the outer wall 32J etc. which divide the upstream space 32S. In the duct 30, the guide portion 30A and the lower end portion of the vertical partition plate 32L of the main body 32 guide the foreign matter T and the water to the outlet 20D. The foreign matter T reaching the extraction port 20D falls into the outer tube 3 from the extraction port 20D and remains in the outer tube 3. The water poured into the vertical surface portion 42A from each water supply port 41G also falls from the pipe 30 into the outer tube 3 and remains in the outer tube 3 like the foreign matter T.

The vertical surface portion 42A of the drying filter 42 is directly exposed in the upstream space 32S constituting the circulation path 20. Therefore, when water is supplied from the water supply port 41G to the vertical surface portion 42A, the foreign matter T attached to the vertical surface portion 42A peels off from the vertical surface portion 42A and quickly falls into the circulation path 20 and reaches the outer cylinder 3 from the outlet 20D.

When a predetermined time has elapsed after the water injection valve 27 is opened, the control unit 24 stops the water supply to the water supply unit 50 by closing the water injection valve 27 and opens the drain valve 12. It should be noted that when the water injection valve 27 is open, the drain valve 12 may always be in the open state. When the drain valve 12 is opened, the water remaining in the outer cylinder 3 flows into the drain path 5 with foreign matter T. That is, the foreign matter T is removed from the outer tube 3 when the outer tube 3 is drained. The foreign matter T flowing into the drain passage 5 is captured by the drain filter 6 (refer to FIG. 1). The foreign matter T captured by the drain filter 6 is removed when the user removes the drain filter 6 at an appropriate time for maintenance.

As described above, in the integrated washer-dryer 1, at a predetermined timing, the water supply unit 50 supplies water to the vertical surface portion 42A of the dryer filter 42 from the upper side Z1. In other words, the washer-dryer 1 has an automatic cleaning function of the drying filter 42 realized by water. Furthermore, the washer-dryer 1 also has an automatic cleaning function of the drying filter 42 realized by the scraping mechanism 60 described later. FIG. 5 is a perspective view of the duct 30, the filter member 25, and the scraping mechanism 60 viewed from the right rear side. The scraping mechanism 60 includes a stay 61 fixed to the pipe 30, and a scraper 62 and an actuator 63 mounted on the stay 61.

The stay 61 has a plate shape, is fixed to, for example, the right part of the outer wall 32J of the main body 32 of the duct 30, and is arranged so as to protrude from the main body 32 to the right side X1. The left end of the stay 61 is arranged to face the lower end of the right end of the vertical surface portion 42A of the drying filter 42 from the rear side Y2.

The scraper 62 is a linear rod, and is arranged between the vertical surface portion 42A of the drying filter 42 and the left end portion of the stay 61 in the front-rear direction Y. On the front surface of the wiper 62, a brush 64 is provided over almost the entire area in the longitudinal direction. The brush 64 is composed of a large number of bristles 64A implanted in the scraper 62. Instead of the brush 64, a blade (not shown) made of rubber or the like may be provided on the wiper 62. The scraper 62 shown in FIG. 5 is in a vertical waiting position. The scraper 62 in the waiting position is in a state of overlapping with the right end of the vertical surface portion 42A of the drying filter 42 when viewed from the back, and the brush 64 is in a state of being in contact with the right end of the vertical surface portion 42A from the rear side Y2. The size of the brush 64 in the vertical direction Z at this time is slightly smaller than the size of the vertical surface portion 42A in the vertical direction Z. The scraper 62 in the waiting position may be arranged on the right side X1 of the right end of the vertical surface portion 42A so as not to overlap the vertical surface portion 42A when viewed from the back. In short, the scraper 62 located in the waiting position is located at a position that does not affect the capture of the foreign matter T by the longitudinal surface portion 42A. The root portion constituting the lower end of the wiper 62 in the waiting position is connected to the stay 61 via a rotation shaft 65 extending in the front-rear direction Y and penetrating the left end of the stay 61. The scraper 62 can rotate with the rotating shaft 65 around the rotating shaft 65.

An example of the actuator 63 is an electric motor. The operation of the actuator 63 is controlled by the control unit 24 (refer to FIG. 1). The actuator 63 is arranged on the right side X1 of the main body 32 of the duct 30, that is, outside the duct 30, and is fixed to the right end of the stay 61 from the front side Y1. The actuator 63 has an output shaft 66 penetrating the right end of the stay 61. The scraping mechanism 60 includes an input gear 67 fixed to the rear end of the rotating shaft 65 of the wiper 62 and an output gear 68 fixed to the rear end of the output shaft 66. The input gear 67 and the output gear 68 are spur gears, which may be directly meshed or connected via a single or multiple relay gears 69 as shown in FIG. 5. When the actuator 63 works, the output shaft 66 rotates with the output gear 68, and the rotation is transmitted to the input gear 67 via the relay gear 69, so that the input gear 67 rotates around the rotation shaft 65 along with the wiper 62 and the rotation shaft 65 .

FIG. 6 is a rear view of the main body 32 of the duct 30, the filter member 25, and the scraping mechanism 60. As shown in FIG. The scraper 62 can rotate between the waiting position shown by the solid line and the scraping position shown by the two-dot chain line. The scraping position is a position when the scraper 62 is rotated counterclockwise, for example, 120 degrees when viewed from the back of the waiting position. The scraper 62 located in the scraping position overlaps with the lower part of the vertical surface portion 42A of the drying filter 42 when viewed from the back. The scraper 62 located at the scraping position may be arranged on the lower side Z2 of the vertical surface portion 42A of the drying filter 42. When the scraper 62 receives the driving force of the actuator 63 and rotates between the waiting position and the scraping position, it follows the vertical portion by scraping almost the entire area of the vertical portion 42A of the drying filter 42 with the brush 64 42A moves. In a state where the main body 32 and the cover 33 are combined to complete the duct 30, in the scraping mechanism 60, at least the scraper 62 is arranged in the arrangement space 32R in the duct 30.

During the drying process, the control unit 24 makes the scraper 62 reciprocate between the waiting position and the scraping position for many times. Thus, the foreign matter T captured by the drying filter 42 and remaining on the vertical surface portion 42A during the drying process is also scraped by the scraper 62 reciprocating along the vertical surface portion 42A and peeled off from the vertical surface portion 42A. The foreign matter T peeled off from the vertical surface portion 42A falls into the circulation path 20 as described above, reaches the outer tube 3 from the outlet 20D, and is removed from the outer tube 3 when the outer tube 3 drains water. It should be noted that it is set to be thicker than the mesh of the drying filter 42 so that the bristles 64A of the brush 64 of the scraper 62 will not be caught by the mesh of the drying filter 42.

When the drying process ends, as described above, the control unit 24 supplies water to the vertical surface portion 42A of the drying filter 42 from the upper side Z1 through the water supply unit 50. This water supply lasts, for example, 1 minute. The foreign matter T adhering to the vertical surface part 42A is peeled from the vertical surface part 42A by this water supply.

It is assumed that the scraper 62 reciprocates during the drying process to scrape the foreign matter T from the longitudinal surface 42A, so that the foreign matter T adheres to the scraper 62, that is, the scraper 62 itself becomes dirty. Therefore, after the end of the drying process, the control unit 24 moves the scraper 62 to the scraping position and stops at the scraping position through the actuator 63 while continuing to supply water to the vertical surface portion 42A through the water supply unit 50, thereby performing Maintenance of the wiper 62. By rotating the scraper 62 here, the foreign matter T remaining in the vertical surface portion 42A is scraped off. Then, the foreign matter T adhering to the wiper 62 can be removed from the wiper 62 by the water (refer to the thick double-dashed arrow in FIG. 6) flowing through the vertical surface 42A by the water supply from the water supply unit 50. Thus, the user does not need to maintain the drying filter 42 nor the wiper 62. Therefore, the maintainability can be improved. When the one-minute water supply by the water supply unit 50 ends, the control unit 24 rotates the wiper 62 and returns to the waiting position. Thus, the maintenance process ends. The time required for the scraper 62 to rotate from the waiting position to the scraping position and return to the waiting position is about 6 seconds.

As described above, since the all-in-one washer-dryer 1 has the automatic cleaning function of the drying filter 42 realized by the water and the wiper 62, the user does not need to remove the drying filter 42 for maintenance. Therefore, the maintenance of the drying filter 42 can be improved. Since the drying filter 42 may be non-detachable, it can simplify the structure and reduce the cost more than the detachable drying filter. In addition, in the case of a removable drying filter, if the user forgets to maintain it, the above-mentioned performance degradation may occur, and the washer-dryer 1 with automatic cleaning function can avoid the performance caused by forgetting to maintain reduce. In addition, since the arrangement space required in the case of the detachable drying filter can be utilized for other purposes, the performance can be improved by, for example, increasing the size of the heating unit 22 and the rotating blade 23.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope described in the technical solution.

For example, as the actuator 63 that moves the wiper 62, it is not limited to the electric motor described above, and a solenoid or the like may be used. In addition, as a mechanism for transmitting the driving force generated by the actuator 63 to the wiper 62, a structure other than the gear transmission mechanism using the aforementioned input gear 67, output gear 68, and relay gear 69 can be exemplified. As an example of this structure, pulleys are attached to the rotation shaft 65 of the wiper 62 and the output shaft 66 of the actuator 63, respectively, and these pulleys are connected with a wire. The wire is pulled out, for example, about half a turn around the pulley of the rotating shaft 65 of the wiper 62, and is connected to an urging member such as a spring. The driving force generated by the actuator 63 is transmitted to the scraper 62 via the wire, so that the scraper 62 rotates from the waiting position to the scraping position. With the urging force of the urging member that is stretched at this time to be retracted, the scraper 62 rotates from the scraping position to the waiting position.

For example, although the scraper 62 can be rotated between the waiting position and the scraping position in the above-mentioned embodiment, it can also be moved linearly in the vertical direction Z or the left and right direction X while maintaining the same posture to wipe off the drying filter. Foreign matter T on the longitudinal surface 42A of the device 42. When the scraper 62 moves linearly in the vertical direction Z, the scraper 62 takes a horizontally long posture, the waiting position is set on the upper end side of the vertical surface portion 42A, and the scraping position is set on the lower end side of the vertical surface portion 42A. When the scraper 62 moves linearly in the left-right direction X, the scraper 62 takes a vertically long posture, and the waiting position is set to one of the left end side and the right end side of the vertical surface portion 42A, and the scraping position is set to the vertical surface portion The other of the left end side and the right end side of 42A.

In the above-mentioned embodiment, although the vertical surface portion 42A of the drying filter 42 is arranged vertically toward the outlet 20D side of the circulation path 20, that is, the upstream side, the vertical surface portion 42A may be arranged in the vertical direction or opposite to It is arranged obliquely in the vertical direction.

The foreign matter T removed from the vertical surface portion 42A of the drying filter 42 and the water dripped onto the vertical surface portion 42A go to the drainage path 5 from the outlet 20D of the circulation path 20 via the outer cylinder 3 in the above-mentioned embodiment. Alternatively, a release hole 32U (refer to FIG. 5) may be provided in the outer wall 32J of the main body 32 of the duct 30 at the lower end of the lower side Z2 of the vertical surface 42A (see FIG. 5), and the drainage channel 5, for example, can be discharged through the flow channel 100. The portion on the upstream side of the filter 6 is connected to the release hole 32U. Thereby, the foreign matter T and the water in the duct 30 can reach the drain path 5 from the release hole 32U and the flow path 100 without passing through the outer tube 3. Thereby, it is possible to prevent foreign matter T and water from adhering to the laundry L in the washing tub 7.

In the washer-dryer 1, the drain filter 6 can be omitted. In this case, the foreign matter T captured by each drying filter 42 and flowing into the outer tube 3 is discharged to the outside of the machine body through the drainage passage 5 (refer to FIG. 1) when the outer tube 3 is drained.

As part of the maintenance process described above, the control unit 24 circulates the air in the outer cylinder 3 through the air blowing unit 21 after stopping the water supply from the water supply unit 50 to the drying filter 42. In this way, the drying filter 42 that has been sprayed with water and moistened in order to remove the foreign matter T is dried by being blown by the air flowing into the circulation path 20 from the outer tube 3. It should be noted that the heating unit 22 may also be operated to circulate hot air, thereby promoting the drying of the drying filter 42. In this way, since the user does not need to dry the drying filter 42, the maintenance of the drying filter 42 can be further improved.

In the drum-type integrated washer-dryer 1 in the above-described embodiment, the washing tub 7 may be arranged such that the axis J is inclined with respect to the horizontal direction H. In addition, the integrated washer-dryer 1 may be a vertical integrated washer-dryer whose axis J extends longitudinally.
