DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, a number of embodiments of the laundry processing device will be described with reference to the drawings. Note that substantially the same elements in the various embodiments are designated by the same reference numerals, and the description thereof will be omitted.

[0009] (First embodiment) The washer-dryer 10 shown in Fig. 1 is an example of a clothes treating device capable of subjecting clothes to a predetermined process, in this case at least a washing process for washing clothes, a rinsing process for rinsing clothes, and a dehydration process for dehydrating clothes. The washer-dryer 10 is a so-called horizontal-axis drum-type washer-dryer in which the central axis of rotation of the rotating tub extends horizontally or in a direction inclined relative to the horizontal. The washer-dryer 10 is also an example of a clothes drying device capable of subjecting clothes to a drying process.

[0010] The washer / dryer 10 is provided with a clothes treatment tub 12 inside a rectangular box-shaped outer casing 11 that forms the outer shell of the washer / dryer. The clothes treatment tub 12 is an example of a clothes storage tub in which clothes (not shown) are stored, and is provided with a water tub 13 and a drum 14. The water tub 13 is elastically supported by a suspension (not shown). The water tub 13 is cylindrical with a closed rear face, and is capable of storing water inside. The drum 14 is provided rotatably within the water tub 13. The drum 14 is cylindrical with a closed rear face.

[0011] Drum 14 can accommodate clothes (not shown) to be subjected to various processes such as washing, rinsing, spin-drying, drying, etc. The peripheral wall and rear surface of drum 14 are provided with a large number of small holes (not shown) that allow ventilation and water to pass through. The inner peripheral surface of drum 14 is provided with a baffle (not shown) for lifting up the clothes. The central axis of rotation of drum 14 extends horizontally or in a direction inclined relative to the horizontal.

[0012] A drum motor (not shown) is provided on the rear surface of the clothing treatment tub 12. The drum motor is capable of rotating a drum 14 inside the water tub 13 in both forward and reverse directions. A front opening of the water tub 13 is configured to be openable and closable by a door 15 provided on the front surface of the outer box 11. By opening the door 15, a user can place clothes in or take clothes out of the water tub 13, or more specifically, the drum 14, through the front opening.

[0013] The washer / dryer 10 is equipped with a water supply unit (not shown) for supplying water into the clothes treatment tub 12. The water supply unit is configured to include a well-known water supply valve, water injection case, etc., in the middle of a water supply path extending from a water source (not shown), such as a water tap, to the clothes treatment tub 12. A predetermined amount of water is stored in the clothes treatment tub 12 by supplying water from the water supply unit into the clothes treatment tub 12.

[0014] The clothing treatment tub 12 is equipped with a common outlet 12a, an air inlet 12b, a water inlet 12c, and an overflow outlet 12d. In this configuration example, the common outlet 12a is provided at the lower front part of the clothing treatment tub 12. In this configuration example, the air inlet 12b is provided at the rear surface of the clothing treatment tub 12. In this configuration example, the water inlet 12c is provided at the lower rear part of the clothing treatment tub 12. In this configuration example, the overflow outlet 12d is provided at the rear surface of the clothing treatment tub 12.

[0015] When the water level in the clothing treatment tub 12 exceeds the height of the overflow outlet 12d, the excess water is discharged outside the clothing treatment tub 12. This limits the maximum water level in the clothing treatment tub 12 to the height of the overflow outlet 12d. The overflow outlet 12d is connected to a portion of the drainage passage 31, which will be described later, downstream of the drainage valve 32.

[0016] The washer / dryer 10 is provided with a circulation air duct 21. The circulation air duct 21 connects the common outlet 12a and the air inlet 12b of the clothing treatment tub 12 outside the clothing treatment tub 12. A circulation fan (not shown) is provided midway along the circulation air duct 21. The circulation fan causes air in the clothing treatment tub 12 to flow out from the common outlet 12a into the circulation air duct 21, and circulates the air that has flowed out into the circulation air duct 21 back into the clothing treatment tub 12 from the air inlet 12b. That is, the circulation air duct 21 functions as an example of an air duct through which the air in the clothing treatment tub 12 flows out.

[0017] Further, a heat pump mechanism 22 is provided in the middle of the circulation air passage 21. In this configuration example, the heat pump mechanism 22 is provided at the rear of the upper part inside the outer casing 11. That is, the heat pump mechanism 22 is provided at a position inside the outer casing 11 that is at least higher than the overflow port 12d.

[0018] Although detailed illustration is omitted, heat pump mechanism 22 constitutes a well-known refrigeration cycle in which a compressor, a condenser, a squeezer, and an evaporator are connected in a cycle by refrigerant pipes. Of these, the condenser and evaporator are arranged inside circulating air duct 21. Washer / dryer 10 dehumidifies the air flowing through circulating air duct 21 by the evaporator, and further heats the air by the condenser and supplies it as hot air into clothing treatment tub 12. In this way, washer / dryer 10 is configured to dry the clothes in clothing treatment tub 12 with hot air.

[0019] The washer / dryer 10 also includes a drainage channel 31. The drainage channel 31 extends from the common outlet 12a of the clothes treatment tub 12 to the outside of the machine, outside the clothes treatment tub 12. A drain valve 32 is provided midway along the drainage channel 31. The drainage valve 32 is switched from a closed state to an open state, causing the water in the clothes treatment tub 12 to flow out of the machine from the common outlet 12a. In other words, the drainage channel 31 functions as an example of a waterway through which the water in the clothes treatment tub 12 flows out.

[0020] The washer / dryer 10 also includes a circulation water channel 41. The circulation water channel 41 connects the common outlet 12a and the water inlet 12c of the clothing treatment tub 12 outside the clothing treatment tub 12. A circulation pump 42 is provided midway along the circulation water channel 41. The circulation pump 42 causes the water in the clothing treatment tub 12 to flow out from the common outlet 12a into the circulation water channel 41, and circulates the water that has flowed out into the circulation water channel 41 back into the clothing treatment tub 12 from the water inlet 12c. In other words, the circulation water channel 41 functions as an example of a channel through which the water in the clothing treatment tub 12 flows out.

[0021] In the washer / dryer 10, part of the circulating air duct 21, part of the drainage duct 31, and part of the circulating water duct 41 are shared. That is, the upstream part of the circulating air duct 21, i.e., the part connected to the common outlet 12a of the clothing treatment tub 12, the upstream part of the drainage duct 31, i.e., the part connected to the common outlet 12a of the clothing treatment tub 12, and the upstream part of the circulating water duct 41, i.e., the part connected to the common outlet 12a of the clothing treatment tub 12, are configured as a common part 51.

[0022] The common section 51 is provided with a common filter accommodating section 52. The common filter accommodating section 52 is formed in a rectangular box shape with an open front. The side of the common filter accommodating section 52, in this case the rear side, is connected to the circulation air passage 21. The bottom of the common filter accommodating section 52 is connected to the drain passage 31 and the circulation water passage 41. The common filter 100 is detachably accommodated in the common filter accommodating section 52 through the front opening. A user can attach and detach the common filter 100 in the common filter accommodating section 52 from the front of the washer / dryer 10.

[0023] 2, the common filter 100 is configured to include a filter body 101 in the form of a rectangular container with an open top, an air channel filter section 102, and a water channel filter section 103. The filter body 101 is configured such that the front surface and both the left and right side surfaces are closed.

[0024] The air duct filter section 102 is provided on a side surface of the filter main body section 101, in this case the rear surface, and captures foreign matter contained in the air flowing through the air circulation duct 21. When the common filter 100 is housed in the common filter housing section 52, the air duct filter section 102 faces the side surface of the common filter housing section 52, i.e., the rear surface connected to the air circulation duct 21.

[0025] The water channel filter section 103 is provided on the bottom surface of the filter main body section 101, and captures foreign matter contained in the water flowing in the drainage channel 31 or the circulation water channel 41. When the common filter 100 is housed in the common filter housing section 52, the water channel filter section 103 faces the bottom surface of the common filter housing section 52, that is, the bottom surface connected to the drainage channel 31 or the circulation water channel 41. Note that foreign matter captured by the air channel filter section 102 or the water channel filter section 103 is, for example, lint and dust generated from clothing.

[0026] The mesh size of the air path filter section 102 and the mesh size of the water path filter section 103 are different, and in this case, the mesh size of the air path filter section 102 is finer than the mesh size of the water path filter section 103. The material of the air path filter section 102 and the material of the water path filter section 103 are also different, and in this case, the air path filter section 102 is made of, for example, metal, and the water path filter section 103 is made of, for example, resin. In this case, the area of ​​the air path filter section 102 and the area of ​​the water path filter section 103 are the same, but they may be different areas.

[0027] As illustrated in Fig. 1, the washer-dryer 10 includes a control device 60, which is an example of a control unit. The control device 60 is mainly configured, for example, with a microcomputer, and controls the overall operation of the washer-dryer 10 based on a control program and various setting information. The control device 60 controls the operation of the water supply valve, drum motor, drain valve 32, etc., described above, to perform a well-known washing operation for washing the clothes in the clothes treatment tub 12, a well-known rinsing operation for rinsing the clothes in the clothes treatment tub 12, a well-known dehydration operation for dehydrating the clothes in the clothes treatment tub 12, and the like. The control device 60 also controls the operation of the circulation blower and heat pump mechanism 22, to perform a drying operation for drying the clothes in the clothes treatment tub 12.

[0028] In the washing and rinsing operations, the control device 60 circulates water through the circulation water passage 41 and discharges water outside the machine through the drain passage 31. That is, the control device 60 drives the circulation pump 42 to circulate the water in the clothes treatment tub 12 through the circulation water passage 41. The control device 60 also opens the drain valve 32 to discharge the water in the clothes treatment tub 12 outside the machine through the drain passage 31.

[0029] 3, the circulating water flowing in the circulating water passage 41 and the wastewater flowing in the drainage passage 31 mainly pass through the water passage filter portion 103 of the common filter 100. This allows the water passage filter portion 103 to capture foreign matter P1 contained in the circulating water flowing in the circulating water passage 41 and the wastewater flowing in the drainage passage 31.

[0030] Furthermore, in the state illustrated in FIG. 3, gravity also acts on the foreign matter P1, so that the foreign matter P1 is easily captured by the water channel filter portion 103 on the bottom surface.

[0031] 3, foreign matter P1 has accumulated in the water channel filter section 103, but no foreign matter has accumulated in the air channel filter section 102, and the air channel is not blocked. Therefore, in this state, that is, with foreign matter P1 accumulated on the water channel filter section 103, the operation can be shifted to the drying operation.

[0032] During the drying operation, the control device 60 circulates air through the circulation air duct 21. That is, the control device 60 drives the circulation fan and the heat pump mechanism 22 to circulate the air in the clothing treatment tub 12 through the circulation air duct 21.

[0033] 4, the circulating air flowing through the circulating air passage 21 mainly passes through the air passage filter portion 102 of the common filter 100. This allows the air passage filter portion 102 to capture the foreign matter P2 contained in the circulating air flowing through the circulating air passage 21.

[0034] According to the washer / dryer 10 configured as described above, by executing a series of washing and drying cycles including a washing operation, a rinsing operation, a spin-drying operation, and a drying operation, foreign matter P1 contained in the circulating water or drainage water during the washing operation and the rinsing operation can be captured by the water path filter unit 103, and foreign matter P2 contained in the circulating air can be captured by the air path filter unit 102 during the drying operation.

[0035] Then, when a washing operation or a rinsing operation is performed during the next operation course, as illustrated in Fig. 5, the foreign matter P2 captured by the air duct filter section 102 can be washed downward by circulating water or drainage and removed from the air duct filter section 102. This makes it possible to prevent the air duct resistance in the circulation air duct 21 from increasing due to the foreign matter P2 accumulated in the air duct filter section 102. Therefore, it is not necessary to clean the air duct filter section 102 every time the drying operation is completed. The foreign matter P2 removed from the air duct filter section 102 is accumulated on the water duct filter section 103 located below the air duct filter section 102.

[0036] In the washer-dryer 10, when drying operations are performed consecutively, that is, when a drying operation is performed, the next drying operation may be performed without performing operations other than the drying operation, that is, without performing a washing operation or a rinsing operation, after the drying operation is performed. In such a case, the cleaning effect of the air duct filter unit 102 by the circulating water or drainage as illustrated in Fig. 5 cannot be achieved. Therefore, when drying operations are performed consecutively, the control device 60 may perform a cleaning operation between the drying operation after the drying operation and the drying operation before the drying operation.

[0037] The cleaning operation is, for example, an operation of circulating the water in the clothing treatment tub 12 through the circulation water passage 41 and discharging the water in the clothing treatment tub 12 through the drain passage 31. That is, the control device 60 can clean the air passage filter section 102 by executing an operation of discharging water into the circulation water passage 41 and the drain passage 31.

[0038] According to such a cleaning operation, even when drying operations are performed consecutively, it is possible to clean the common filter 100, particularly the air passage filter portion 102, before each drying operation, and to prevent an increase in air passage resistance in the circulating air passage 21 during the drying operation. Note that the cleaning operation may be, for example, an operation of spraying cleaning water into the common filter 100 from a dedicated cleaning nozzle.

[0039] In addition, the washer-dryer 10 may be configured so as not to be able to perform the cleaning operation as described above. In this case, when performing consecutive drying operations, the user only needs to manually clean the inside of the common filter 100 before performing each drying operation.

[0040] According to the exemplary configuration of the washer-dryer 10 described above, a part of the circulation air duct 21, a part of the drainage duct 31, and a part of the circulation water duct 41 are shared by the common section 51, and the common section 51 is provided with a common filter 100 including an air duct filter section 102 and a water duct filter section 103. According to this exemplary configuration, by performing maintenance such as cleaning on one component, the common filter 100, it is possible to perform maintenance such as cleaning on both the water duct filter section 103 and the air duct filter section 102. Therefore, the workload of filter maintenance can be reduced for the washer-dryer 10 including the circulation air duct 21 through which the air in the clothing treatment tub 12 flows out, and the drainage duct 31 and the circulation water duct 41 through which the water in the clothing treatment tub 12 flows out.

[0041] Regarding the air duct filter section 102, since the heat pump mechanism 22 is present downstream thereof, it is preferable that the mesh size is as fine as possible so that even finer foreign matter can be captured. On the other hand, regarding the water duct filter section 103, it is necessary to ensure a certain degree of water permeability, and therefore the mesh size does not need to be as fine as that of the air duct filter section 102.

[0042] In the washer / dryer 10, the mesh size of the air path filter section 102 and the mesh size of the water path filter section 103 are made different, specifically, the mesh size of the air path filter section 102 is made finer than the mesh size of the water path filter section 103. According to this configuration example, it is possible to realize a configuration in which the air path filter section 102 can capture finer foreign matter, and the water path filter section 103 can capture foreign matter while ensuring a certain degree of water permeability.

[0043] The air path filter section 102 needs to be heat resistant because hot air passes through it during drying operation, and the material is preferably made of metal, for example. On the other hand, the water path filter section 103 does not need to be heat resistant because water passes through it during washing and rinsing operations, and the material can be made of resin, for example.

[0044] In the washer / dryer 10, the material of the air path filter section 102 is different from the material of the water path filter section 103, and specifically, the air path filter section 102 is made of, for example, metal, and the water path filter section 103 is made of, for example, resin. According to this configuration example, the air path filter section 102 can ensure heat resistance by being made of, for example, metal, and the water path filter section 103 can be made of, for example, resin, allowing it to be inexpensively formed.

[0045] Moreover, the metallic air-path filter unit 102 has high strength, so that foreign matter can be easily removed using, for example, a brush. Moreover, the metallic air-path filter unit 102 can be easily formed with a fine mesh size.

[0046] According to the washer / dryer 10, the control device 60 can execute a cleaning operation to clean the common filter 100. According to this configuration example, the common filter 100 on which foreign matter has accumulated can be appropriately cleaned, and the burden of maintenance work such as cleaning by the user can be reduced.

[0047] In the washer / dryer 10, when the next drying operation is performed without performing any operation other than the drying operation after the drying operation is performed, the control device 60 performs a cleaning operation between the subsequent drying operation and the previous drying operation. According to this configuration example, even when the drying operations are performed consecutively, the common filter 100 can be cleaned before each drying operation.

[0048] In the washer / dryer 10, the common filter 100 has an air path filter section 102 on its side surface and a water path filter section 103 on its bottom surface. That is, the common filter 100 is configured such that the air path filter section 102 is located above the water path filter section 103. According to this configuration example, foreign matter removed from the air path filter section 102 by the cleaning operation can be received by the water path filter section 103. Therefore, when cleaning the common filter 100, the user only needs to remove foreign matter from the water path filter section 103, which reduces the user's workload.

[0049] Second embodiment 6, the washer-dryer 10 has the heat pump mechanism 22 disposed at the rear of the lower part inside the outer casing 11. That is, the heat pump mechanism 22 is disposed at a position lower than at least the overflow port 12d inside the outer casing 11. The washer-dryer 10 has a raised portion 23 in the circulation air passage 21 on the downstream side of the common filter 100, i.e., on the heat pump mechanism 22 side. The raised portion 23 is curved so as to rise from the upstream side and then descend toward the downstream side, and its upper end reaches a position higher than the overflow port 12d.

[0050] According to this configuration example, even if the water level in the clothing treatment tub 12 reaches the height of the overflow outlet 12d, the raised portion 23 can prevent the water in the clothing treatment tub 12 from flowing through the circulation air passage 21 toward the heat pump mechanism 22. This makes it possible to prevent the water from reaching the heat pump mechanism 22. In this configuration example, the raised portion 23 functions as an example of a blocking portion that blocks water from flowing toward the heat pump mechanism 22.

[0051] Third embodiment 7 is configured to include ribs 24 in a portion of circulation air duct 21 closer to heat pump mechanism 22 than common filter 100, instead of raised portion 23. According to this configuration example, even if water in clothing treatment tub 12 attempts to flow through circulation air duct 21 toward heat pump mechanism 22, the flow of water can be blocked by ribs 24, and water can be prevented from flowing toward heat pump mechanism 22. In this configuration example, ribs 24 function as an example of a blocking portion that blocks water from flowing toward heat pump mechanism 22.

[0052] (Fourth embodiment) The washer / dryer 10 shown in Fig. 8 is configured to include a branch water passage 25 in a portion of the circulation air passage 21 closer to the heat pump mechanism 22 than the common filter 100, instead of the raised portion 23 described above. The tip of the branch water passage 25 is connected to a portion of the drain passage 31 downstream of the drain valve 32. According to this configuration example, even if water in the clothing treatment tub 12 attempts to flow through the circulation air passage 21 toward the heat pump mechanism 22, the water can be directed to flow into the branch water passage 25 upstream of the heat pump mechanism 22, and the water can be prevented from flowing toward the heat pump mechanism 22. In this configuration example, the branch water passage 25 functions as an example of a blocking portion that blocks water from flowing toward the heat pump mechanism 22.

[0053] Fifth embodiment 9 is configured to include an on-off valve 26 in a portion of the circulation air duct 21 closer to the heat pump mechanism 22 than the common filter 100, instead of the raised portion 23 described above. According to this configuration example, even if water in the clothing treatment tub 12 attempts to flow through the circulation air duct 21 toward the heat pump mechanism 22, the flow of water can be stopped by switching the on-off valve 26 from an open state to a closed state, and the water can be prevented from flowing toward the heat pump mechanism 22. In this configuration example, the on-off valve 26 functions as an example of a blocking portion that blocks water from flowing toward the heat pump mechanism 22.

[0054] Sixth embodiment 10 is configured to further include an auxiliary filter 200 that is separate from the common filter 100. The auxiliary filter 200 is provided in a portion downstream of the air path filter section 102 in the circulation air path 21, and in a portion downstream of the water path filter section 103 in the drainage path 31 or the circulation water path 41. According to this configuration example, even if a foreign object passes through the air path filter section 102 or the water path filter section 103, the foreign object can be captured by the auxiliary filter 200, thereby improving the foreign object capturing performance.

[0055] The washer-dryer 10 may be configured to include a plurality of auxiliary filters 200 in a downstream portion of the air path filter unit 102 in the circulation air path 21. The washer-dryer 10 may be configured to include a plurality of auxiliary filters 200 in a downstream portion of the water path filter unit 103 in the drainage path 31 or the circulation water path 41. The washer-dryer 10 may be configured to include the auxiliary filter 200 in a downstream portion of the air path filter unit 102 in the circulation air path 21, and not include the auxiliary filter 200 in a downstream portion of the water path filter unit 103 in the drainage path 31 or the circulation water path 41. Alternatively, the washer-dryer 10 may be configured to include the auxiliary filter 200 in a downstream portion of the water path filter unit 103 in the drainage path 31 or the circulation water path 41, and not include the auxiliary filter 200 in a downstream portion of the air path filter unit 102 in the circulation air path 21.

[0056] (Other embodiments) This embodiment is not limited to the above-mentioned embodiments, and various modifications and extensions can be made without departing from the gist of the present invention. For example, the washer / dryer 10 may be configured by appropriately selecting and combining at least two or more of the above-mentioned embodiments. The shape of the common filter 100 is not limited to a rectangular container, and may be, for example, a cylindrical container with a part of the side open, with an air channel filter section on the side and a water channel filter section on the bottom.

[0057] The mesh size of the air path filter section 102 and the mesh size of the water path filter section 103 may be the same. Furthermore, the material of the air path filter section 102 and the material of the water path filter section 103 may be the same. In this case, by using the same material for the air path filter section 102 and the water path filter section 103 as the filter main body section 101, it is possible to integrally mold the entire common filter 100 including the filter main body section 101, the air path filter section 102, and the water path filter section 103.

[0058] This embodiment is not limited to a so-called horizontal-axis drum-type washer-dryer in which the rotation axis of the rotating tub extends horizontally or in an inclined direction, but can also be applied to a so-called vertical-axis washer-dryer in which the rotation axis of the rotating tub extends vertically. In addition, this embodiment can also be applied to a clothes drying device that does not have a washing function.
