As shown in FIGS. 2 to 4, the washing tub 35 includes a water tank 30 and a rotating tub 40 housed therein, and the rotating tub 40 is housed inside the water tub 30. The water tank 30 is cylindrical and has a bottom, and is housed within the housing 20 and supported by a suspension structure such as a damper. The water tank 30 is arranged to open at a position corresponding to the door 22 provided on the front surface 20a of the housing 20. The water tank 30 is connected by piping to a water supply and drainage section 80, which will be described in detail later. Thereby, the water tank 30 can store water supplied from the outside inside, and can discharge the water inside to the outside. Further, the water tank 30 has a washing tub intake section 32 and a washing tub exhaust section 34.

The washing tub intake part 32 is provided in the water tub 30 at a position on the front side 20a side. In this embodiment, the water tank 30 has a gasket 36 on the front side 20a, and the gasket 36 is provided with a washing tank intake part 32. Further, the washing tub exhaust part 34 is provided at a position on the back surface 20b side of the water tub 30. Further, the water tank 30 is connected to a ventilation path 50, which will be described in detail later, via a washing tank intake section 32 and a washing tub exhaust section 34. Thereby, the water tank 30 can introduce air flowing through the ventilation path 50 from the washing tub intake part 32 on the front side 20a side and exhaust it from the washing tub exhaust part 34 on the back side 20b side. Although the washing tub intake section 32 has been described as an example of a configuration in which air is sucked into the rotating tub 40 by being provided in the gasket 36, it may also be configured to blow air into the rotating tub 40 via the washing tub intake section 32. .

The rotating tank 40 is a tank rotatably housed inside the water tank 30. The rotating tank 40 is cylindrical and has a bottom. Like the water tank 30, the rotating tank 40 is arranged to open at a position corresponding to the door 22 provided on the front surface 20a of the housing 20. Therefore, by opening the door 22 of the washing machine 10, laundry can be taken in and out of the rotating tub 40. The rotating tank 40 can be rotated by a drive device (not shown) such as a motor installed at the rear of the water tank 30. The rotating tank 40 is provided with a plurality of openings around its circumference that communicate the inside and outside. Therefore, by storing water in the water tank 30, the washing machine 10 can also introduce water into the rotating tank 40. Furthermore, by draining water from the water tank 30, the washing machine 10 can also drain water from the rotating tub 40.

As shown in FIGS. 2 and 3, the ventilation path 50 forms a ventilation path from the washing tub exhaust part 34 of the water tank 30 to the washing tub intake part 32 outside the water tank 30. That is, as shown in the arrow by the dashed line in FIG. 3, 5, and FIG. This is a path for the airflow to reach the washing tub intake part 32 of No. 30. By blowing air through the air blowing path 50, it is possible to generate an airflow inside the water tank 30 from the front side to the back side. The air blowing path 50 runs from the upstream side (washing tank exhaust part 34 side) to the downstream side (washing tank intake part 32 side) in the air flow direction outside the water tank 30, including an exhaust side communication part 52 (communication part), an intermediate It can be roughly divided into three parts: a portion 54 and an intake side communication portion 56.

The exhaust side communication part 52 is a part that communicates with the washing tub exhaust part 34 of the water tank 30. The exhaust side communication section 52 has a communication section 58 and a water receiving section 60. The communication portion 58 is a passage formed to stand up on the back surface 20b side with respect to the water tank 30. The communication portion 58 is connected to the washing tub exhaust portion 34 at one end side (lower end side). Thereby, the communication section 58 can cause the air discharged from the washing tub exhaust section 34 to flow in the direction from below to above. Further, the other end side of the communicating portion 58 is connected to a water receiving portion 60 . The water receiving part 60 is for receiving water supplied by a water supply part 82, which will be described in detail later, and for washing the inner circumferential surface of the communicating part 58 by dropping the received water into the communicating part 58.

The intermediate portion 54 is located at an intermediate portion of the air flow path 50 in the flow direction of the airflow, with the washing tub exhaust portion 34 of the water tank 30 on the upstream side and the airflow flowing to the washing tub intake portion 32 of the water tank 30 . That is, the intermediate portion 54 is a portion of the ventilation path 50 that is located downstream in the airflow direction of the ventilation path 50 from the exhaust side communication portion 52 that connects to the washing tub exhaust section 34 of the water tank 30 . The intermediate portion 54 is located on the top surface 20e side with respect to the water tank 30. The intermediate portion 54 is arranged to extend from the back surface 20b side of the housing 20 toward the front surface 20a side. A filter device 100, which will be described in detail later, is arranged in the intermediate portion 54. This makes it possible to remove foreign substances such as lint contained in the air passing through the ventilation path 50. Further, the intermediate portion 54 can introduce outside air into the ventilation path 50 or discharge air flowing through the ventilation path 50 via the outside air introduction section 140 and the inside air discharge section 130 provided in the filter device 100. can.

The air intake side communication part 56 is located in the ventilation path 50 , with the washing tank exhaust part 34 of the water tank 30 on the upstream side and the air flow flowing to the washing tank intake part 32 of the water tank 30 on the downstream side in the flow direction. That is, the intake-side communication portion 56 is a portion of the air blowing path 50 that is continuous on the downstream side with respect to the intermediate portion 54 and connected to the washing tub intake portion 32 of the water tank 30 . The intake-side communication portion 56, like the intermediate portion 54, is located on the top surface 20e side with respect to the water tank 30. A warm air supply section 70, which will be described in detail later, is arranged in the intake side communication section 56. Thereby, the air from which foreign matter has been removed by the filter device 100 in the intermediate section 54 can be heated by the hot air supply section 70. The suction side communication part 56 is connected to the washing tub suction part 32 at the terminal end.

The warm air supply section 70 is for supplying warm air to the washing tub intake section 32 provided in the water tank 30. As shown in FIG. 7, the hot air supply unit 70 includes a blower device 72 and a heating device 74. The blower device 72 is for forming an airflow in the air blowing path, and can be configured by, for example, a conventionally known blower fan or the like. Further, the heating device 74 heats the air flowing through the ventilation path 50 by the operation of the ventilation device 72. The heating device 74 can be configured by a conventionally known electric heater or the like.

As shown in FIGS. 2 and 3, the water supply and drainage section 80 includes a water supply section 82 and a drainage section 84. The water supply section 82 has a water supply channel connected to an external water supply source, and is capable of supplying water to the water tank 30. For example, the water supply section 82 may be one that can directly supply water supplied from a water supply source to the aquarium 30, or one that can supply detergent, softener, etc. in a separately provided input section midway through the water supply channel leading to the aquarium 30. can be supplied to the aquarium 30 in the form of mixed water in which the water is mixed with water. The drainage section 84 has a drainage channel connected to the water tank 30 separately from the water supply section 82 . The drainage section 84 is capable of discharging water in the water tank 30 through the aforementioned drainage channel.

The filter device 100 is disposed at the intermediate portion 54 in the middle of the air blowing path 50 described above. The filter device 100 is for collecting foreign matter such as lint contained in the air.

The washing machine 10 is generally configured as described above. Hereinafter, of the configurations of the above-mentioned parts, parts that require a more detailed explanation will be specifically explained with reference to the drawings.

<<About the filter device 100>>
The filter device 100 will be described in more detail and specifically below. The filter device 100 is provided in the middle of the ventilation path 50 as described above. As shown in FIG. 2, FIG. 5, FIG. 6, etc., in this embodiment, the filter device 100 is provided in the intermediate portion 54 of the ventilation path 50. As shown in FIG. 8, the filter device 100 includes a filter housing section 110, an inside air exhaust section 130, an outside air introduction section 140, and a filter member 150. The filter device 100 is a unit in which a filter housing section 110, an inside air exhaust section 130, and an outside air introduction section 140 are integrated, and a filter member 150 is removably attached to this unit.

The filter accommodating portion 110 forms a space through which air flowing through the ventilation path 50 can pass, and in which the filter member 150 can be accommodated. As shown in FIGS. 8 to 10, the filter accommodating portion 110 is open toward the top surface 20e of the housing 20, and the filter member 150 can be attached and detached through this opening. The filter accommodating portion 110 has an opening so as to have a substantially rectangular shape in a plan view, and has an upstream opening 112, a downstream opening 114, an inside air discharge portion communication port 116, and an outside air introduction portion communication port 118 on its inner circumference. .

The upstream opening 112 is open at an upstream inner circumferential surface 110 a of the inner circumferential surface of the filter accommodating portion 110 , which is on the upstream side of the air flow flowing through the ventilation path 50 . The downstream opening 114 opens at a downstream inner circumferential surface 110b that is on the downstream side of the airflow flowing through the ventilation path 50. The downstream opening 114 is formed in a region of the downstream inner circumferential surface 110b on the side where the outside air introduction port communication port 118 is provided. The downstream inner circumferential surface 110b is a surface facing the upstream inner circumferential surface 110a. The inside air discharge part communication port 116 is provided upright so as to intersect (substantially orthogonally in this embodiment) with the upstream inner circumferential surface 110a and the downstream inner circumferential surface 110b of the inner circumferential surface of the filter accommodating part 110. It is open at the first lateral inner circumferential surface 110c. The inside air exhaust section communication port 116 is an opening that allows the filter accommodating section 110 and the inside air exhaust section 130 to communicate with each other. The inside air exhaust section communication port 116 is also a part that constitutes an inside air exhaust section 130, which will be described later. In addition, the outside air introduction part communication port 118 is an opening in a second lateral inner peripheral surface 110d of the inner peripheral surface of the filter accommodating part 110, which is erected to face the first lateral inner peripheral surface 110c. are doing. The outside air introduction section communication port 118 is an opening that allows the filter accommodating section 110 and the outside air introduction section 140 to communicate with each other. The outside air introduction section communication port 118 is also a part that constitutes an outside air introduction section 140, which will be described later.

The filter accommodating portion 110 has a drain port 120, an inclined portion 122, a guide groove 124, and an engaged portion 126 on the bottom portion 110e. The drain port 120 is an opening for discharging moisture such as dew water from the filter accommodating portion 110. The drain port 120 is provided in the bottom portion 110e at a position adjacent to the downstream inner circumferential surface 110b and the second lateral inner circumferential surface 110d. The drain port 120 is connected to the communication section 58 on the upstream side of the filter device 100 in the air flow direction via a drain pipe 120a outside the filter housing section 110 so as to allow drainage. The inclined portion 122 is a portion where the bottom portion 110e slopes downward toward the drain port 120. Thereby, the filter accommodating part 110 is configured to be able to guide moisture that has fallen to the bottom 110e within the filter accommodating part 110 toward the drain port 120. Further, the guide groove 124 is a groove for reliably and easily attaching and detaching a downstream filter member 180 forming a filter member 150 which will be described in detail later. The guide groove 124 is recessed to match the shape of the lower end of the downstream filter member 180. The engaged portion 126 is a portion that engages with an engaging portion 190 provided at the upper end of the downstream filter member 180.

Moreover, a part or all of the inner circumferential surface of the filter accommodating portion 110 has an uneven shape in a pleated shape. In this embodiment, the upstream inner circumferential surface 110a, the first lateral inner circumferential surface 110c, and the second lateral inner circumferential surface 110d have an uneven shape in a pleated shape. As a result, moisture such as condensed water in the filter accommodating portion 110 gradually falls toward the bottom portion 110e and the drain port 120. By doing so, it is possible to evaporate even a small amount of condensed water under the influence of the airflow passing through the filter housing part 110, and it is possible to reduce the amount of water flowing back from the drain port 120 to the communication part 58. can.

The inside air exhaust part 130 is a part that communicates with the filter accommodating part 110 and is open to the outside so that air can be exhausted from the ventilation path 50 to the outside. The inside air exhaust section 130 has the above-mentioned inside air exhaust section communication port 116, an inside air exhaust path 132, and an inside air exhaust port 134. The inside air exhaust path 132 communicates with the filter accommodating section 110 via the inside air exhaust section communication port 116. The inside air exhaust path 132 is a passage that connects the inside air exhaust portion communication port 116 and the inside air exhaust port 134. The inside air exhaust port 134 is an opening provided at the end of the inside air exhaust path 132 on the opposite side to the inside air exhaust communication port 116.

Here, the inside air outlet communication port 116 is an opening formed in the first lateral inner circumferential surface 110c that is upright in the filter housing section 110, whereas the inside air outlet 134 is directed toward the top surface 20e. It was opened. Therefore, the inside air exhaust path 132 connecting both openings is bent approximately 90 degrees in the middle. The inside air exhaust passage 132 is formed so that a bent part provided in the middle has a curved surface (R shape) in order to minimize the pressure loss of the airflow passing through the inside. In addition, the inside air exhaust section 130 is configured such that the opening area of the inside air exhaust port 134 is larger than the opening area of the inside air exhaust section communication port 116 in order to suppress the exhaust speed of the airflow (exhaust air) exiting from the inside air exhaust port 134. It is formed. According to this configuration, the exhaust speed at the inside air outlet 134 can be reduced. As a result, it is possible to suppress exhaust gas from being vigorously discharged around the washing machine 10. For example, even if the washing machine is installed in a place with close walls around it, such as a washing machine installation space in a narrow apartment. It can also prevent moisture-laden exhaust air from hitting the wallpaper. As a result, it is possible to prevent dew condensation from adhering to the surface of the wallpaper and the growth of microorganisms such as mold due to contact with the exhaust air from the washing machine 10.

The outside air introduction section 140 communicates with the filter accommodating section 110 and is open to the outside so that air (outside air) can be introduced into the ventilation path 50 from the outside. The outside air introduction section 140 is located on the opposite side of the inside air discharge section 130 with the filter accommodating section 110 interposed therebetween. Furthermore, the outside air introduction section 140 has the same configuration as the inside air exhaust section 130 described above.

Specifically, the outside air introduction section 140 includes the above-mentioned outside air introduction section communication port 118, an outside air introduction path 142, and an outside air introduction port 144. The outside air introduction path 142 communicates with the filter housing section 110 via the outside air introduction section communication port 118. The outside air introduction path 142 is a passage that connects the outside air introduction portion communication port 118 and the outside air introduction port 144. The outside air introduction port 144 is an opening provided at the end of the outside air introduction path 142 on the opposite side to the outside air introduction portion communication port 118.

Further, like the inside air exhaust path 132, the outside air introduction path 142 is bent approximately 90 degrees in the middle. Specifically, the outside air introduction port 118 is an opening formed in the second side inner circumferential surface 110d of the filter accommodating portion 110, whereas the outside air introduction port 144 is an opening formed toward the top surface 20e. This is what I did. Therefore, the outside air introduction path 142 is bent approximately 90 degrees in the middle. The outside air introduction path 142 is formed so that a bent part provided in the middle has a curved surface (R shape) in order to minimize the pressure loss of the airflow taken in from the outside. Furthermore, the outside air introduction section 140 is formed such that the opening area of the outside air introduction port 144 is larger than the opening area of the outside air introduction section communication port 118. This allows outside air to be taken in efficiently.

As shown in FIG. 8, the filter member 150 collects foreign substances contained in the air flowing through the ventilation path 50. In the washing machine 10 of the present embodiment, an upstream filter member 160 and a downstream filter member 180 are arranged as the filter members 150 in the air flow direction in the ventilation path 50.

As shown in FIGS. 11 and 12, the upstream filter member 160 has an upstream filter 164 attached to an upstream filter main body 162. As shown in FIGS. The upstream filter member 160 can be inserted into and removed from above the filter accommodating portion 110 that is open toward the top surface 20e. The upstream filter main body 162 has a closing portion 166 , an upstream erected portion 168 , a first lateral erected portion 170 , a second lateral erected portion 172 , and a partition wall 174 .

The closing portion 166 closes the opening of the filter accommodating portion 110 provided on the top surface 20e side when the upstream filter member 160 is inserted into the filter accommodating portion 110. The closing portion 166 has a depression 166a on the surface exposed to the top surface 20e. The recess 166a is provided to make it easier for the user to grasp the upstream filter member 160 when inserting and removing the upstream filter member 160 into the filter accommodating portion 110, and is designed to allow multiple fingers to be inserted into the recess 166a. There is.

The upstream side upright portion 168 is a portion that stands up along the upstream inner peripheral surface 110a in a state where the upstream filter member 160 is fitted into the filter housing portion 110 described above. The upstream upright portion 168 is erected on the back side (bottom side) of the closing portion 166 so as to be substantially perpendicular to the closing portion 166 . The upstream side erected portion 168 has at least a portion corresponding to the upstream side opening 112 in order to minimize resistance to the airflow flowing into the filter accommodating portion 110 from the upstream side opening 112 provided on the upstream side inner circumferential surface 110a. It is said that it has a lattice shape. A mesh-like upstream filter 164 is attached to the upstream upright portion 168 over the entire area formed in a grid shape. Further, an upstream seal portion 168a is attached around the portion where the upstream filter 164 is attached to maintain airtightness and watertightness. The upstream seal portion 168a can be made of various materials, but in this embodiment, one made of EPDM rubber is used.

The first lateral upright portion 170 is a portion that is erected along the first lateral inner circumferential surface 110c when the upstream filter member 160 is fitted into the filter accommodating portion 110 described above. Like the upstream side erected portion 168, the first side erected portion 170 is erected substantially perpendicularly to the occlusion portion 166 on the back side (bottom side) of the occlusion portion 166.

Like the upstream side upright portion 168, the first side upright portion 170 is designed to minimize resistance to the airflow passing through the inside air outlet communication port 116 and being exhausted from the filter accommodating portion 110. , at least a portion corresponding to the internal air exhaust communication port 116 is shaped like a grid.

The second lateral upright portion 172 is a portion that is erected along the second lateral inner circumferential surface 110d when the upstream filter member 160 is fitted into the filter housing portion 110 described above. The second lateral erected portion 172, like the upstream erected portion 168 and the first lateral erected portion 170, is erected substantially perpendicularly to the occlusion portion 166 on the back side (bottom side) of the occlusion portion 166. has been done. Further, the second lateral erected portion 172 intersects with the upstream erected portion 168 (in this embodiment They are formed so that they are substantially perpendicular to each other. The second lateral erected portion 172 is substantially parallel to the first lateral erected portion 170. Further, like the upstream side upright portion 168 and the first side upright portion 170, the second side upright portion 172 is designed to reduce the resistance of the air flow that passes through the outside air introduction portion communication port 118 and is introduced into the filter accommodating portion 110. In order to minimize this, at least the portion corresponding to the outside air introduction port communication port 118 is shaped like a grid.

The partition wall 174 partitions the internal space of the filter accommodating portion 110 into a first space 176 and a second space 178. Specifically, the partition wall 174 is erected substantially perpendicularly to the closing portion 166 on the back side (bottom side) of the closing portion 166, similar to the upstream standing portion 168 and the like. In addition, the partition wall 174 intersects (mainly crosses) the upstream side standing portion 168 at the middle portion in the width direction of the upstream side standing portion 168 (between the first side standing portion 170 and the second side standing portion 172). In the embodiment, they are formed so as to be substantially perpendicular to each other. The partition wall 174 is substantially parallel to the first side upright portion 170 and the second side upright portion 172. As a result, the partition wall 174 divides the opening area formed in the upstream upright portion 168 into an area where the outside air introduction part communication port 118 exists and an area where the inside air discharge part communication port 116 exists. be able to. Further, the partition wall 174 is formed so as to reach the downstream inner circumferential surface 110b when the upstream filter member 160 is fitted into the filter housing portion 110. Therefore, the partition wall 174 divides the internal space of the filter accommodating part 110 into a first space 176 that communicates with the downstream opening 114 and the outside air introduction part communication port 118, and a second space 178 that communicates with the inside air discharge part communication port 116. It can be divided into

As shown in FIG. 13, the downstream filter member 180 is a filter that is attached across the opening area of the downstream opening 114. The downstream filter member 180 has a downstream filter 184 attached to a downstream filter frame 182. Like the upstream filter member 160, the downstream filter member 180 can be inserted into and removed from above the filter housing portion 110 that is open toward the top surface 20e.

Specifically, the downstream filter frame 182 is a member to which the downstream filter 184 is attached. The downstream filter frame 182 has a filter mounting portion 186, a grip portion 188, an engaging portion 190, and a downstream seal portion 192.

The filter attachment portion 186 is a portion to which the downstream filter 184 is attached. The filter attachment portion 186 has a flat, grid-like shape. A net-shaped downstream filter 184 is attached to the filter attachment portion 186 . Further, the lower end side of the downstream filter frame 182 has a shape that can be inserted into the guide groove 124 provided in the bottom portion 110e of the filter accommodating portion 110 described above.

The grip portion 188 is provided at a portion that becomes the upper end portion of the downstream filter member 180 in the attached state. The grip portion 188 is curved in a curl shape from the upper end of the filter attachment portion 186 formed in a planar shape. The grip portion 188 is curved in a direction away from the downstream inner circumferential surface 110b so as not to prevent the filter attachment portion 186 and the downstream inner circumferential surface 110b from coming into close contact with each other when the downstream filter member 180 is attached. There is.

The engaging portion 190 is for fixing the downstream filter member 180 to the downstream inner circumferential surface 110b of the filter accommodating portion 110. The engaging portion 190 is configured to engage with an engaged portion 126 provided on the downstream inner circumferential surface 110b. In this embodiment, the engaging portion 190 is shaped like a claw, and the engaged portion 126 is a recess into which the engaging portion 190 can be inserted and engaged.

The downstream seal portion 192 is attached to surround the portion to which the downstream filter 184 is attached so that it can be interposed between the filter attachment portion 186 and the downstream inner circumferential surface 110b when the downstream filter member 180 is attached. It is being Therefore, when the downstream filter member 180 is attached, airtightness and watertightness are maintained between the filter attachment portion 186 and the downstream inner peripheral surface 110b. The downstream seal portion 192 can be made of various materials, but in this embodiment, one made of EPDM rubber is used. By providing the downstream filter member 180 in this manner, even if the user forgets to attach the upstream filter member 160, for example, the downstream filter member 180 can capture lint. In addition, by taking in outside air from the outside air introduction section 140, the moist circulating airflow sent from the washing tub 35 to the intermediate section 54 is cooled in the filter housing section 110 (reducing the amount of saturated water vapor), and the downstream filter member 180 It can also cause condensation water. By generating dew condensation water in this way, it is possible to make it difficult for lint to adhere to the downstream filter member 180 or to cause the lint to flow down from the downstream filter member 180.

≪About the water receiving part 60≫
Next, the water receiving portion 60 will be specifically and detailedly explained with reference to the drawings. As described above, the water receiver 60 is provided on the upstream side of the air flow path 50 with respect to the filter device 100 in the air flow direction. The water receiving portion 60 is connected to an end of a communication portion 58 that forms the exhaust side communication portion 52 of the ventilation path 50 .

As shown in FIGS. 14 and 15, the water receiving portion 60 has a bottom surface 60a and an outer edge portion 60b that stands up to form the outer edge of the bottom surface 60a. Thereby, water can be introduced into the water receiving part 60 into the area surrounded by the outer edge part 60b. Further, the outer edge portion 60b is provided with a connecting portion 60c that is pipe-connected to the water supply and drainage portion 80. The connecting portion 60c is formed to protrude outward from the outer edge portion 60b. As a result, water is introduced into the water receiving part 60 in a direction crossing the outer edge 60b (direction along the bottom surface 60a) through the connecting part 60c. Can be sent. Note that the connecting portion 60c is not limited to a configuration in which it is provided in a direction that intersects the opening direction of the opening portion 62, and the connecting portion 60c may be provided as long as the arriving position (landing position) of the supplied water is the water receiving portion 60. may be provided along the opening direction.

Further, the water receiving portion 60 is provided with an opening portion 62, an upright portion 64, and a groove portion 66. The opening 62 is an opening formed in the bottom surface 60a of the water receiving portion 60 so as to communicate with the communication portion 58. The opening shape of the opening portion 62 is formed to match the opening shape and size at the end of the communication portion 58. The upright portion 64 is a portion erected to surround the opening 62. In this embodiment, the upright portion 64 is erected along the opening edge of the opening 62, but may be erected outside the opening 62 so as to surround the opening 62. According to such a configuration, a part of the water introduced from the connecting part 60c is dammed up by the upright part 64 and stored along the outer edge part 60b of the water receiving part 60, and the other water is is dropped into the opening 62 by climbing over the standing portion 64 or from the groove 66 . The groove portion 66 is a groove provided in the upright portion 64. The groove portion 66 is provided at one or more locations in the upright portion 64 .
In addition, in this embodiment, although the structure which has both the upright part 64 and the groove part 66 was demonstrated as an example, the structure which does not have both the upright part 64 and the groove part 66 may be sufficient, or the upright part 64 and a configuration in which one of the grooves 66 is provided (in the case of a configuration in which only the groove 66 is provided, a configuration in which the groove 66 is provided around the opening 62) may be used. Further, the number and size of the grooves 66 can be set as appropriate, but for example, more grooves 66 may be arranged in the portion of the communication portion 58 where lint is likely to adhere, or the number and size of the grooves 66 may be increased from the connection portion 60c that serves as the water inflow port. It is possible to vary the arrangement density of the groove portions 66 depending on the distance between them. In this embodiment, as shown in FIG. 14, more grooves 66 are provided on the side where lint tends to adhere, and the connecting portions 60c are arranged. Therefore, by introducing water into the water receiving part 60, the water is preferentially flowed to the side of the communication part 58 where lint tends to adhere, thereby making it possible to wash the communication part 58 evenly.

The water receiving section 60 has the above-described configuration, and allows water supplied by the water supply and drainage section 80 from a direction intersecting the opening direction of the opening section 62 (approximately horizontal direction in this embodiment) to drop into the communication section 58. It can be washed with water (lint washing with running water). Lint washing with running water can be carried out at any appropriate timing, for example, at the timing when water is supplied to the water tank 30 for washing or rinsing during a washing operation, or within a predetermined time after a drying operation when the drain valve is closed. This can be done at a time when the switch can be left open.

≪About the hot air supply section 70≫
Next, characteristic parts of the hot air supply unit 70 will be specifically and detailedly explained with reference to the drawings. As described above, the hot air supply section 70 supplies warm air to the washing tub intake section 32 provided in the water tank 30. As shown in FIG. 7 , the warm air supply unit 70 includes a blower device 72 for forming an airflow in the blower path 50 and a heating device 74 for heating the air flowing through the blower path 50 .

Here, the heating device 74 is disposed in a narrowed portion 52a of the exhaust side communication portion 52 located midway in the air blowing path 50, where the passage cross-sectional area is narrower than that on the upstream side. Therefore, the hot air supply unit 70 can efficiently exchange heat with the air flowing through the ventilation path 50 in the heating device 74, and can heat the air smoothly. Further, the heating device 74 is disposed further downstream than the blower device 72, and can heat the air immediately before entering the water tank 30. Therefore, while the heated air flows through the ventilation path 50, it is possible to suppress to a minimum the heat dissipation, temperature drop, and moisture absorption while the heated air flows through the ventilation path 50. This makes it possible to introduce air with the highest temperature and lowest possible humidity into the water tank 30, thereby improving the drying efficiency of the laundry in the water tank 30.

≪About the housing 20≫
Next, characteristic parts of the casing 20 will be described in detail with reference to the drawings. As shown in FIGS. 1 to 3, the housing 20 has a main body portion 26a and a pedestal portion 26b. Further, the housing 20 has a connecting portion 26c, as shown in FIG. 16.

The main body part 26a is a part that accommodates the water tank 30, the rotating tank 40, the air passage 50, the water receiving part 60, the hot air supply part 70, the water supply and drainage part 80, the filter device 100, and the like. The main body portion 26a includes a front beam 28a disposed on the front surface 20a side on the top surface 20e side, a rear beam 28b disposed on the rear surface 20b side, and a pair of side beams 28c disposed on the left side surface 20c and right side surface 20d side. , 28d.

The side beams 28c and 28d are beams extending in the front-rear direction on the left side and the right side, and are connected to the front beam 28a and the rear beam 28b.

In the main body portion 26a, a member forming the ventilation path 50 is suspended from each beam. Specifically, the air blowing path 50 includes a base structure 50 a forming the lower half of the air blowing path 50 , a filter accommodating structure 50 b forming a peripheral portion around the filter accommodating section 110 , and a hot air supply section 70 . It has a hot air supply unit structure 50c that forms a central and peripheral portion. The air blowing path 50 is constructed by assembling a filter housing section structure 50b and a hot air supply section structure 50c onto a base structure 50a. When suspending the ventilation path 50 from each beam, the base structure 50a is first suspended from the front beam 28a, the rear beam 28b, and the side beams 28c. Thereafter, the filter accommodating part structure 50b and the hot air supply part structure 50c are assembled onto the base structure 50a. In this way, in the washing machine 10, the air passage 50 can be assembled by a simple procedure using each beam forming the main body portion 26a. Further, the main body portion 26a has a high-strength front beam 28a, a rear beam 28b, and side beams 28c, 28d on the upper side, and has a highly rigid structure. In view of the characteristics of the main body portion 26a, in the washing machine 10, the air passage 50, which is heavier than other components and is likely to generate vibrations due to air blowing, is suspended and assembled on each of the beams 28a to 28d. . Therefore, in the washing machine 10, the ventilation path 50 can be stably maintained.

The pedestal portion 26b is arranged below the main body portion 26a as a pedestal for the main body portion 26a. The pedestal portion 26b has substantially the same size and shape as the main body portion 26a in plan view. The pedestal portion 26b is provided with a cavity penetrating in the vertical direction at the center in a plan view. Further, the portion of the pedestal portion 26b that forms the peripheral portion surrounding the cavity also has a honeycomb-like shape having a large number of through holes penetrating in the vertical direction. Thereby, weight reduction is achieved without impairing the strength of the pedestal portion 26b.

Further, the peripheral portion of the pedestal portion 26b has a shape cut out from the top surface 20e side toward the bottom surface 20f side on the front surface 20a side. Therefore, when the main body part 26a is placed on the pedestal part 26b, an opening part 26d opened toward the outside in the circumferential direction is formed between the two parts. The opening 26d is provided on the lower side of the housing 20 for various purposes such as inserting hands or tools into the inside of the housing 20, routing drainage piping, updating printed circuit boards, maintenance, etc. It can be used for

The connecting portion 26c connects the main body portion 26a and the pedestal portion 26b, and improves vibration isolation and rigidity. The connecting portion 26c has a main body side fixing portion 26e and a pedestal side fixing portion 26f. The main body side fixing part 26e is attached to the bottom of the main body part 26a at a position on the front surface 20a side over substantially the entire width direction. Further, the pedestal side fixing part 26f is attached to the top of the pedestal part 26b at a position on the front surface 20a side over substantially the entire width direction.

Specifically, the main body side fixing part 26e has a main body side front plate 26g extending in the left-right direction at the lower front surface of the main body part 26a. The pedestal-side fixing portion 26f includes pedestal-side side beams 26h, 26i fastened to the left and right upper surfaces of the pedestal portion 26b, and a pedestal-side front plate 26j extending in the left-right direction on the front upper surface of the pedestal portion 26b. Further, the pedestal side beams 26h and 26i are provided with a connecting portion 26k to which a suspension structure (not shown) such as a damper that supports the water tank 30 is connected. The connecting portion 26c fastens the upper surface of the pedestal-side front plate 26j and the lower surfaces of the pedestal-side side beams 26h, 26i to the pedestal-side side beam 26h using fasteners such as screws, and also connects the lower surface of the main body-side front plate 26g. and the upper surfaces of the pedestal-side side beams 26h, 26i are fixed by fastening with fasteners such as screws. In this way, the connecting portion 26c integrates the main body portion 26a and the pedestal portion 26b by connecting and fixing the main body side fixing portion 26e and the pedestal side fixing portion 26f with the fixing tool, and improves vibration isolation and rigidity. You can improve your performance.

In the washer/dryer of Patent Document 1, an intake port for introducing outside air and an exhaust port for discharging inside air are provided spaced apart in the circulating air path. Therefore, in the case of the configuration disclosed in Patent Document 1, the lint filter device must have a wide (horizontally long) shape, for example, corresponding to the arrangement of the intake port and the exhaust port. There was a problem in that it could be a hindrance to making effective use of the limited space inside the machine's housing.

It is said that the structure is as follows. In this way, the washing machine 10 has a configuration in which the outside air introduction section 140 and the inside air exhaust section 130 are integrated in the filter housing section 110.

It is characterized by:

According to this configuration, the exhaust speed at the inside air outlet 134 can be reduced. Thereby, it is possible to suppress exhaust gas from being vigorously discharged around the washing machine 10. As a result, even if the washing machine is installed in a place close to walls, such as a washing machine installation space in a narrow apartment building, it is possible to suppress exhaust gas containing moisture from hitting the wallpaper. As a result, it is possible to prevent dew condensation from adhering to the surface of the wallpaper and the growth of microorganisms such as mold due to contact with the exhaust air from the washing machine 10.

Furthermore, by providing two filters consisting of the upstream filter member 160 and the downstream filter member 180, compared to the case where a single filter is provided, the humid air flowing through the ventilation path 50 and the outside air introduction part 140 are separated from each other. By mixing the taken in outside air in the filter accommodating part 110, the temperature of the humid air flowing through the ventilation path 50 is lowered (the amount of saturated water vapor is lowered), and the contained moisture is efficiently converted into dew water. Can be separated and removed. Furthermore, the lint contained in the air passing through the filter accommodating portion 110 can be made difficult to adhere to the upstream filter member 160 and the downstream filter member 180 by the condensed water, or even if the lint has adhered, the condensed water can It can be flowed down.

Here, as described above, by providing the upstream filter member 160 and the downstream filter member 180 in the filter accommodating portion 110, moisture contained in the humid air flowing through the ventilation path 50 can be efficiently converted into dew water. In the case of a configuration in which dew condensation water can be separated and removed, it is desirable to have a configuration that can suppress accumulation of dew condensation water in the filter accommodating portion 110. Based on this knowledge, it is desirable to have the following configuration (1-6), for example.

[About the specific example of the first modification]
Hereinafter, a washing machine 10 according to a first modification will be described in detail with reference to the drawings. Note that since the washing machine 10 according to this modification has most of the configurations in common with those according to the above embodiment, the same configurations are denoted by the same reference numerals, and detailed explanations will be omitted.

The washing machine 10 includes a housing 20, a washing tub 35, a ventilation path 50, a ventilation device 72, and a heating device 74, similar to those exemplified in the above embodiment. As shown in FIG. 17, the washing machine 10 of this modification includes a hot water forming section 200, a room temperature detection device 210, and a control section 220 in addition to these components.

The hot water forming section 200 is for making water used for washing and rinsing hot water. The hot water generating section 200 is constituted by a heater that generates heat when energized. The hot water forming unit 200 can heat low-temperature water supplied from the outside to generate hot water. The hot water forming section 200 can be provided at an appropriate location, such as the washing tub 35, for example. The hot water forming section 200 is operable under the control of the control section 220.

Room temperature detection device 210 includes a temperature sensor for detecting the temperature inside the room where washing machine 10 is installed. The room temperature detection device 210 is capable of outputting data related to the detected room temperature to the control unit 220.

The control unit 220 controls the overall operation of the washing machine 10. The control unit 220 is connected to the hot water forming unit 200 and the room temperature detection device 210. Further, the control unit 220 is connected to a motor for driving the rotating tub 40 in the washing tub 35, a blower device 72, and a heating device 74. Thereby, the control unit 220 is able to control the rotation of the rotary tank 40, the air blowing by the air blower 72, the heating by the heating device 74, and the like.

The control unit 220 performs a washing process in which the laundry placed in the washing tub 35 is washed, a rinsing process in which the laundry placed in the washing tub 35 is rinsed, and a dehydration process in which the laundry placed in the washing tub 35 is dehydrated. The operation of the washing machine 10 is controlled so that the washing machine 10 is operated in an operation mode consisting of only one process selected from a plurality of processes including a dehydration process, or an operation mode consisting of a combination of a plurality of processes selected from these processes. be able to. The washing machine 10 of this modification is operated in an operation mode that includes one or both of a washing process and a rinsing process, and a dehydration process, and uses hot water supplied by a hot water supply unit to perform washing and washing. When performing one or both of the rinsing operations, the dehydration blowing operation can be performed under the control of the control unit 220. Hereinafter, the air blowing operation during dehydration will be described in detail with reference to the timing chart shown in FIG. 18.

In the example shown in the timing chart of FIG. 18, the washing machine 10 is operated in an operating mode in which each process is performed in the order of washing process, first dehydration process, rinsing process, second dehydration process, third dehydration process, and drying process. Drive. Here, the washing process is a process of washing the laundry put into the washing tub 35. In the operation mode illustrated in the timing chart of FIG. 18, washing is performed using water heated by the hot water forming section 200 in the washing process. Moreover, the first dehydration process is a dehydration process performed after the washing process and before moving to the rinsing process. The rinsing step is a step in which water is again poured into the washing tub 35 to rinse the laundry after the first dehydration step. The second dehydration step is a preliminary dehydration step performed after the rinsing step and before the third dehydration step. The third dehydration step is a dehydration step for further dehydrating the laundry after the second dehydration step. The drying process is a process for drying the laundry that has been sufficiently dehydrated in the third dehydration process using warm air supplied to the washing tub 35.

When washing is performed using hot water in the washing process according to the above-mentioned operation mode, the control unit 220 controls at least one of the first dehydration process, the second dehydration process, and the third dehydration process included in the operation mode. In either case, the blower device 72 is operated so that airflow is generated in the air blowing path 50 (air blowing operation during dehydration). The air blowing operation during dehydration is performed at least in the dehydration step immediately after washing or rinsing using hot water. In the example of FIG. 18, hot water is used in the washing process. Therefore, the control unit 220 performs the dehydration blowing operation at least in the first dehydration process performed after the washing process. In the example of FIG. 18, the control unit 220 controls the operation of the air blower 72 so that the air blowing operation during dehydration is performed not only in the first dehydration process but also in the second dehydration process and the third dehydration process.

The control unit 220 rotates the rotating tank 40 at the maximum rotation speed in some of the dehydration processes included in the operation mode. Further, the control unit 220 rotates the rotating tank 40 at the maximum rotation speed in at least the last dehydration step among the plurality of dehydration steps included in the operation mode. In the example shown in the timing chart of FIG. 18, the rotating tank 40 is rotated at the maximum rotation speed in the third dehydration step that is performed last among the first dehydration step, the second dehydration step, and the third dehydration step. Take control.

Further, the control unit 220 controls the heating device 74 to stop heating the air when performing the dehydration blowing operation in the dehydration process that is performed immediately after washing or rinsing using hot water. In the example of FIG. 18, since hot water is used in the washing process, the control unit 220 controls the heating device 74 to air the stop heating.

The control unit 220 controls the air blowing capacity of the air blower 72 to be adjusted continuously or in stages according to the room temperature detected by the room temperature detection device 210 when performing the air blowing operation during dehydration. In this modification, the room temperature is divided into three stages: when the room temperature is low as in the winter, when the room is at a medium temperature like in the spring or autumn, and when the room is high like in the summer. Temperature ranges are specified for easy understanding. Further, the air blowing capacity of the air blower 72 is defined in three stages depending on the rotation speed of the fan included in the air blower 72. Furthermore, the relationship between the room temperature and the air blowing capacity of the air blower 72 is defined in advance. For example, when the room temperature is high, there is a low possibility that dew condensation will occur, so the blowing capacity of the blower device 72 is specified to be the lowest. On the other hand, when the room temperature is low, there is a high possibility that dew condensation will occur, so the air blowing capacity of the air blower 72 is specified to be high. Furthermore, when the room temperature is at a medium level, the air blowing capacity of the air blower 72 is also specified to be at a medium level. The control unit 220 controls the air blowing capacity of the air blower 72 according to predetermined regulations, based on the relationship between the room temperature and the air blowing capacity thus defined, and the room temperature detected by the room temperature detection device 210. Control.

The control unit 220 performs control such that the air blowing time by the air blowing device 72 during the air blowing operation during dehydration is adjusted continuously or in stages according to the room temperature detected by the room temperature detection device. For example, as described above, the control unit 220 grasps the room temperature by dividing the room temperature into three levels: high temperature, low temperature, and medium temperature. The control unit 220 sets the air blowing time of the air blower 72 to a standard time when the room temperature is moderate. When the room temperature is high, since there is a low possibility that dew condensation will occur, the control unit 220 controls the air blowing time by the air blower 72 to be shorter than the standard time. Further, when the room temperature is low, there is a high possibility that dew condensation will occur, so control is performed to make the air blowing time by the air blower 72 longer than the standard time. In this way, the control unit 220 performs control to adjust the air blowing time by the air blower 72 according to the room temperature detected by the room temperature detection device 210.

The control unit 220 performs control to delay the start timing of the air blowing operation during dehydration from the start timing of the dehydration process. Specifically, the control unit 220 delays the start of the dehydration blowing operation until the rotation speed of the rotation tank 40 reaches a predetermined rotation speed after the rotation tank 40 starts rotating in the dehydration process. Specifically, the rotation speed of the rotating tank 40 is set to a predetermined rotation speed defined in the range of 30 to 60% of the maximum rotation speed (in the example shown in FIG. 18, the rotation speed is approximately 40% of the maximum rotation speed). ) The start of the air blowing operation during dehydration is delayed until reaching . Further, after the rotation speed of the rotating tank 40 reaches a predetermined rotation speed, the dehydration air blowing operation is controlled to start.

As described above, the washing machine 10 of this modification is operated in an operation mode in which one or both of washing and rinsing is performed using the hot water supplied by the hot water forming unit 200, and a dehydration process is performed at least once. When this is performed, a dehydration blowing operation is performed in which the blower device 72 generates airflow in the blowing path 50 in at least one of the one or more dehydrating steps included in the operation in the operating mode. Therefore, when operating in an operation mode in which one or both of washing and rinsing is performed using hot water, the humidity is reduced by the airflow flowing through the ventilation path 50 by performing the dehydration fan operation in the dehydration process. , dew condensation can be suppressed.

In addition, in the washing machine 10 of this modification, among the plurality of dehydration processes included in the operation mode, the dehydration blowing operation is performed at least in the dehydration process performed immediately after washing or rinsing using hot water. . Therefore, in the dehydration process that is performed immediately after the humidity increases due to washing or rinsing using hot water, airflow can be caused to flow through the ventilation path 50 to lower the humidity. Thereby, occurrence of dew condensation in the ventilation path 50 can be further suppressed.

As described above, in the washing machine 10 of this modification, the rotating tub 40 is rotated at the maximum rotation speed in some of the dehydrating processes included in the operation mode. Therefore, moisture remaining or attached to the rotating tank 40 can be removed, and drying of the rotating tank 40 can be promoted. Moreover, the water blown off from the rotary tank 40 can be dried by performing an air blowing operation during dehydration. Therefore, according to the above-described configuration, it is possible to more reliably suppress the occurrence of dew condensation.

In addition, in this modification, an example was shown in which the rotating tank 40 was rotated at the maximum rotation speed in some of the plurality of dehydration processes included in the operation mode, but the present invention is not limited to this. Not limited. For example, the rotating tank 40 may be rotated at the maximum rotation speed in all dehydration steps, or may be rotated at a rotation speed lower than the maximum rotation speed in all the dehydration steps.

The washing machine 10 of this modification rotates the rotating tub 40 at the maximum rotation speed in at least the last spin-drying step among the plurality of spin-drying steps included in the operation mode. Therefore, in the washing machine 10, the water remaining or attached to the rotating tub 40 can be removed more reliably, and the drying of the rotating tub 40 can be promoted.

In addition, in this modification, an example was shown in which the rotary tank 40 was rotated at the maximum rotation speed in at least the last dehydration step among the plurality of dehydration steps included in the operation mode, but the present invention It is not limited to this. Specifically, the rotating tank 40 may not be rotated at the maximum rotation speed even in the last dehydration step.

Further, the washing machine 10 of this modification includes a heating device 74 that heats the air passing through the air blowing path 50, and performs a blowing operation during spin-drying at least in a spin-drying process that is performed immediately after washing or rinsing using hot water. When performing this, heating of the air by the heating device 74 is stopped. Therefore, according to the washing machine 10 of this modification, power consumption due to the operation of the heating device 74 can be suppressed.

Note that in this modification example, in the dehydration process that is performed immediately after washing or rinsing using hot water, heating of the air by the heating device 74 is stopped when performing the air blowing operation during dehydration. The invention is not limited to this. That is, the washing machine 10 may heat the air using the heating device 74 in the dehydration step immediately after washing or rinsing using hot water.

The washing machine 10 of this modification described above has a room temperature detection device 210 that detects the room temperature, and the air blowing capacity of the air blower 72 in the air blowing operation during dehydration is adjusted according to the room temperature detected by the room temperature detection device 210. It is something that Therefore, the washing machine 10 of this modification can blow air with the optimum air blowing capacity depending on the level of the room temperature. Thereby, the air can be blown at an optimum amount to suppress the occurrence of dew condensation, and dew condensation can be efficiently suppressed.

In addition, although the washing machine 10 of this modified example is exemplified as one in which the air blowing capacity of the air blower 72 during the air blowing operation during dehydration is adjusted according to the room temperature detected by the room temperature detection device 210, the present invention is not limited to this. Not limited. Specifically, the washing machine 10 is designed so that the air blowing capacity of the air blower 72 during the air blowing operation during spin drying is the same regardless of the room temperature, and the washing machine 10 is equipped with a clock function so that the seasons can be known. Alternatively, the air blowing capacity may be changed depending on the season.

The washing machine 10 of this modification has a room temperature detection device 210 that detects the room temperature, and adjusts the air blowing time by the air blower 72 in the air blowing operation during dehydration according to the room temperature detected by the room temperature detection device 210. has been done. Therefore, according to the washing machine 10 of this modification, the air blowing time can be optimized depending on the level of the room temperature. Thereby, it is possible to prevent air from being blown for an excessively long time in order to suppress the occurrence of dew condensation, thereby reducing operating time and power consumption. In addition, sufficient ventilation time can be ensured taking into account the height of the room temperature, and the occurrence of dew condensation can be efficiently suppressed.

In addition, although the washing machine 10 of this modification is supposed to adjust the air blowing time by the air blower 72 in the air blowing operation during spin-drying according to the room temperature, the present invention is not limited to this. For example, the washing machine 10 can be configured such that the air blowing time by the air blower 72 during the air blowing operation during spin drying is the same regardless of the room temperature, or the washing machine 10 is equipped with a clock function so that the season can be kept track of. The air blowing time may be changed accordingly.

In the washing machine 10 of this modification, the air blowing operation during spin-drying is started with a delay from the start timing of the spin-drying process. Therefore, according to the washing machine 10 of this modification, air containing a large amount of moisture can be suppressed from flowing through the ventilation path 50 immediately after the start of the dehydration process.

In addition, although in this modification example, the air blowing operation during dehydration is started with a delay from the start timing of the dehydration step, the present invention is not limited to this. That is, in the washing machine 10, the air blowing operation during spin-drying may be started at the same timing as the spin-drying process.

In the washing machine 10 of this modification, the start of the air blowing operation during spin-drying is delayed from when the rotating tub 40 starts rotating in the spin-drying process until the rotational speed of the rotating tub 40 reaches a predetermined rotational speed. . Therefore, in the washing machine 10 of this modified example, the water exists at the beginning of the dewatering process from when the rotary tub 40 starts rotating until the rotational speed of the rotary tub 40 reaches a predetermined rotational speed. Air containing a large amount of moisture can be prevented from flowing through the ventilation path 50.

In addition, in the washing machine 10 of this modified example, an example was shown in which the start of the air blowing operation during dehydration is delayed until the rotation speed of the rotating tub 40 reaches a predetermined rotation speed in the dehydration process, but the present invention is not limited to this. Not limited. For example, the washing machine 10 may be one in which the air blowing operation during spin-drying is started after a predetermined period of time has elapsed from the start timing of the spin-drying process.

The washing machine 10 of this modification shows an example in which the use of hot water in the washing process is a condition for performing the air blowing operation during dehydration, regardless of the temperature of the hot water supplied by the hot water forming unit 200 in the washing process. However, the present invention is not limited thereto. Specifically, the air blowing operation during dehydration may be performed on condition that the temperature of the hot water supplied by the hot water forming section 200 is equal to or higher than a predetermined reference temperature. As a result, when hot water at a temperature where condensation is likely to occur is used for washing or rinsing, the air blowing operation during dehydration can be performed appropriately, and hot water at a temperature at which condensation is less likely to occur is used. In some cases, it is possible to omit the air blowing operation during dehydration.

In addition, in this modification, an example was shown in which the air blowing operation during dehydration is performed according to the temperature of the hot water supplied by the hot water forming section 200, but the present invention is not limited to this. That is, the washing machine 10 may perform the air blowing operation during dehydration regardless of the temperature of the hot water supplied by the hot water forming section 200.
