[0008] <Embodiment>

[0009] 1. Overview The schematic structure of the washing machine X according to the embodiment will be described with reference to FIGS. Washing machine X has a washing function, a spinning function, and a drying function. The washing machine X includes a water tub 11 arranged in a housing 10, a rotating tub 12 rotatably arranged within the water tub 11, a hot air generating unit 21 that generates hot air, an air inlet for blowing the hot air into the rotating tub 12, and an outlet for discharging air from within the rotating tub 12. The rotation center of the rotatable tub 12 of the washing machine X is horizontal or inclined so that the opening 12a (see FIG. 8) side of the rotatable tub 12 is higher. In other words, the washing machine X is a drum type. Here, the direction in which the rotation center of the rotating tub 12 extends is defined as the front-rear direction, the side where the door 13 (opening 12a of the rotating tub 12) for putting in and taking out laundry and items to be dried is located is defined as the front side, and the direction perpendicular to the up-down direction and the front-rear direction is defined as the left-right direction. Note that right and left are based on the state in which the washing machine X is viewed from the position facing the door 13.

[0010] Specifically, washing machine X comprises, in housing 10 or frame 19, water tub 11 for storing wash water etc., rotatable tub 12 provided inside water tub 11 and accommodating laundry such as clothes and items to be dried, door 13 for opening and closing opening 11a of water tub 11, motor 14 for rotating rotatable tub 12, drying unit 20 for drying the laundry (items to be dried), water supply unit 15 for supplying water to water tub 11, operation unit 16 for operating washing operation and drying operation etc., control unit for operating washing operation and drying operation etc., drainage unit 17 for draining water from water tub 11, and treatment agent dispenser 18 for dispensing laundry treatment agent into rotatable tub 12.

[0011] 2. Aquarium The following description will be mainly made with reference to FIG. Water tub 11 has a peripheral portion 111 and a bottom portion 112. Bottom portion 112 forms a rear wall located on the rear side in the front-to-rear direction, and bottom portion 112 is provided with motor 14. Furthermore, peripheral portion 111 forms a cylindrical peripheral wall. In other words, water tub 11 is cylindrical with a bottom. The water tank 11 is equipped with a water supply section (water supply port) 117 for supplying water to the rotating tank 12, a drainage section (drainage port) 118 for discharging water, an inlet 28a (see Figure 8(a)) for blowing warm air into the rotating tank 12, and an outlet 27a (see Figure 5(b)) for discharging air from inside the rotating tank 12. As shown in Figure 9(b), lid 113 at the front end of water tub 11 has opening 113a, and ring-shaped ring body 114 is provided on the back side of lid 113. Ring body 114 has fitting portion 114d on the inner periphery of opposing portion 114a that faces lid 113, which fits into opening 113a of lid 113. As a result, opening 11a of water tub 11 is formed by the opening inside fitting portion 114d of ring body 114.

[0012] 3. Rotating tank The following description will be mainly made with reference to FIG. The rotating tub 12 includes a rotating tub main body 123 having a peripheral portion 121 and a bottom portion 122, a plurality of lifters 124 (for example, three) provided at intervals in the rotation direction (circumferential direction) on the inner peripheral surface of the peripheral portion 121, and a pulsator 125 provided on the bottom portion 122. Here, the rotating tub 12 includes an annular balancer 127 provided at the front end portion. The lifter 124 is a protrusion that protrudes from the inner circumferential surface toward the center of rotation and extends in the direction of the center of rotation. A plurality of holes 126 are provided on the inner peripheral surface of rotatable tub body 123, i.e., on at least one of periphery 121 and bottom 122. This allows wash water and warm air to flow into rotatable tub 12 and allows wash water and warm air (air) inside rotatable tub 12 to flow out through holes 126. The rotating tub 12 of this embodiment has a plurality of holes 126 at least in the bottom portion 122, and these holes 126 are configured with a mesh structure. The mesh structure refers to a net-like or lattice-like structure, and the shape of the holes is not particularly limited.

[0013] 4. Processing agent injection section The following description will be mainly made with reference to FIG. The treatment agent dispenser 18 includes a manual dispenser 18A and an automatic dispenser 18B for dispensing the laundry treatment agent into the rotating tub 12. The manual dispenser 18A and the automatic dispenser 18B dispense laundry treatment agents stored in the tanks 181, 182. For convenience of distinction, the tanks are referred to as a manual dispenser tank and an automatic dispenser tank. Replenishing of the processing agent into the manual feeding tank 181 of the manual feeding section 18A and removal of the processing agent from the automatic feeding tank 182 are performed by opening and closing the door 102 on the top wall 101 of the housing 10 shown in FIG. The water supplied from the water supply unit 15 passes through the treatment agent supply section 18 and flows into the water tank 11 from the water supply section 117 of the water tank 11 .

[0014] 5. Drying unit The explanation will be mainly based on FIG. The drying unit 20 includes a hot air generating section 21 that generates hot air, blows the generated hot air into the rotating drum 12 through an inlet 28a (see FIG. 8), and discharges the air from inside the rotating drum 12 to the outside through an outlet 27a (see FIG. 5(a)). Drying unit 20 further has a communication air passage that connects exhaust port 27a and air inlet 28a outside rotating tub 12. The communication air passage is formed inside communication air passage portion 22. The drying unit 20 includes a filter section 23 that captures lint contained in the air flowing through the communication air passage section 22. Drying unit 20 includes exhaust section 24 for exhausting a portion of the air inside rotating tub 12, i.e., a portion of the air flowing through the communicating air passage, to the outside of housing 10, and intake section 25 for supplying air from outside housing 10 to hot air generator 21 (which is, for example, the communicating air passage). This allows dry air to be supplied into rotating tub 12. Hot air generator 21 is disposed in the communication air passage. As a result, the hot air generated by hot air generator 21 flows in the order of hot air generator 21, air inlet 28a, rotating tub 12, outlet 27a, and hot air generator 21, and "upstream" and "downstream" are defined based on the direction of this air flow. Here, an example where the air inlet 28a is located in front of the air outlet 27a (front air outlet) is referred to as Example 1, and an example where the air inlet 44a is located behind the air outlet 43a (rear air outlet) is referred to as Example 2.

[0015] (1) Example 1 (front blowout) (1-1) Hot air generating section As shown in FIG. 3, the hot air generating unit 21 is disposed above the water tub 11. 4, the hot air generating unit 21 is configured by at least a heating unit 211. The hot air generating unit 21 of this embodiment includes the heating unit 211 and an air blowing unit 212. The heating section 211 includes a heater 213 and a case 214 that houses the heater 213. The case 214 constitutes a part of the communicating air passage section 22, and the heater 213 is provided so as to heat the air flowing inside the case 214. 5(a), the blower 212 includes a fan 215, a casing 216 that houses the fan 215, and a motor 217 that rotates and drives the fan 215. The casing 216 forms part of the communicating air passage 22, and the fan 215 is rotated and driven by the motor 217 so that air flows from an inlet to an outlet of the casing 216. The motor 217 is disposed on the upper wall side of the casing 216, and an inlet is formed in the lower wall of the casing 216. The heating section 211 is disposed downstream of the blower section 212. As a result, the blower section 212 is supplied with air whose temperature has been reduced by passing through the rotating tub 12, thereby suppressing thermal deterioration of the blower section 212. Heating unit 211 and blower unit 212 may be connected by a member (cylindrical body) whose interiors are capable of communicating, but here they are connected adjacent to each other. That is, the inlet of case 214 of heating unit 211 is directly connected to the outlet of casing 216 of blower unit 212.

[0016] (1-2) Filter section As shown in Fig. 5, the filter unit 23 includes a filter body 231 that captures lint and a case 232 that houses the filter body 231. The filter body 231 is detachably provided in the case 232. In Fig. 5, the filter unit 23 is arranged behind the air blower 212, but it is sufficient that the filter unit 23 (case 232) is arranged outside the projected range of the air blower 212 so as not to overlap with the air blower 212 when viewed from above. For convenience, the case 214 that houses the heater 213 and the case 232 that has the filter body 231 are referred to as the heater case 214 and the filter case 232, respectively. The filter case 232 constitutes a part of the communicating-air-passage section 22, and is provided so that air flowing from the inlet to the outlet of the filter case 232 passes through the filter body 231. The direction from the inlet to the outlet is the forward direction in the front-to-rear direction (including the direction intersecting with the front-to-rear direction) when viewed from above. The filter unit 23 is disposed upstream of the air blowing unit 212. This makes it possible to prevent lint from flowing into the air blowing unit 212 and the heating unit 211. The filter case 232 has a box-shaped case body 233 that is open at the top. The case body 233 has an outlet 233b (see FIG. 5(b)) in its bottom wall, through which air flows out to the blower 212, and an inlet in its side wall (e.g., the rear wall), through which air flows into the filter case 232. A top wall 234a (lid 234) of the filter body 231 forms part of the top wall 101 of the housing 10 when attached to the filter case 232. The filter body 231 has a grip 235 on its top wall 234a that is gripped by a user when attaching or detaching the filter body 231 (for example, when cleaning the filter body 231). A door 105 that covers the top wall 234a of the filter body 231 may be provided in the housing 10, and the filter body 231 may be removed by opening or closing the door 105.

[0017] (1-3) Exhaust and intake sections The explanation will be mainly based on FIG. The exhaust section 24 and the intake section 25 are provided, for example, by utilizing the filter case 232 of the filter section 23. The filter case 232 has at least two compartments on the downstream side of the filter body 231, with the exhaust section 24 provided in communication with one of the compartments and the intake section 25 provided in communication with the other compartment. The two chambers are arranged in a direction perpendicular to the up-down direction and the direction of flow of air that has passed through the filter body 231, that is, in the left-right direction in this case. The two chambers are separated by a partition wall 237 (see FIG. 5(b)) that is provided on the cover body 234 of the filter case 232 and is perpendicular to the left-right direction. 6, the exhaust unit 24 has an exhaust-side duct 241 that extends upward from the periphery of a through-hole in a wall (for example, the left wall) 233a that constitutes one of the rooms, and air is exhausted from an opening 242 of the exhaust-side duct 241. The opening 242 faces upward and faces the through-hole 103 in the upper wall 101 of the housing 10 as shown in FIG. 6, intake unit 25 has intake duct 251 extending laterally (to the right in the left-right direction) from the vicinity of the through-hole in wall (for example, the right wall) 233b constituting the other room, and air is taken in through opening 252 of intake duct 251. Above opening 252, through-hole 104 in top wall 101 of housing 10 is located as shown in FIG.

[0018] (1-4) Communicating air duct (communicating air duct) As shown in Figure 3(a), the communicating air path section 22 includes a casing 216 and heater case 214 of the hot air generating section 21, a filter case 232 of the filter section 23, a connection section 221 connecting the filter case 232 and the casing 216, a connection section 222 connecting the blowing section 28 having the blowing port 28a and the heater case 214, and a connection section 223 connecting the exhaust section 27 having the exhaust port 27a and the filter case 232. Here, for ease of distinguishing between connection parts 221, 222, and 223, the connection part connecting filter case 232 and casing 216 will be referred to as the intermediate side connection part, the connection part connecting blow-in part 28 and heater case 214 will be referred to as the blow-in side connection part, and the connection part connecting discharge part 27 and filter case 232 will be referred to as the discharge side connection part.

[0019] (1-4-1) Intermediate connection part The intermediate connection portion 221 connects an outlet 233b (see FIG. 5(b)) in the lower wall of the filter case 232 and an inlet in the lower wall of the casing 216 so that they can communicate with each other. As shown in Figure 7, intermediate connection part 221 is located at one end in the left-right direction (right end side) of imaginary line 1L1 that extends in the front-to-rear direction through the left-to-right center of water tub 11. This allows intermediate connection part 221 to be located below filter case 232 and casing 216, preventing the vertical size from increasing. This also makes it possible to effectively use the large space above cylindrical water tub 11 that extends in the front-to-rear direction and on one end in the left-to-right direction. In FIG. 7, imaginary line 1L1 is the central axis of water tub 11 and the center of rotation of rotating tub 12. As shown in Figure 6, intermediate connection section 221 is composed of case body 233 of filter case 232 and cover 224 provided below case body 233. Case body 233 has extension section 233a extending in a plate-like manner from the bottom toward blower section 212, with an outlet formed in extension section 233a. Cover 224 is box-shaped with an open top and extending in the front-to-rear direction, and as shown in Figure 6(a), side wall 224a on the other side in the left-right direction (left wall) is arc-shaped to fit the outer periphery of cylindrical water tub 11. This allows the gap between cover 224 and water tub 11 to be small.

[0020] (1-4-2) Inlet side connection As shown in FIG. 4, the blowing section 28 is made up of a water tank 11 and a blowing tool 227. As shown in FIG. 9, water tub 11 has an annular lid portion 113 that projects radially inward from the front end of circumferential portion 111, and a ring body 114 provided on the back side of lid portion 113. The water tub 11 has a through-hole 111b for a blowing tool 227 formed so as to be continuous with the front end 111a of the peripheral portion 111 and the lid portion 113. The ring body 114 has an opposing portion 114a that faces the lid portion 113, a protruding portion 114b that protrudes radially outward from the opposing portion 114a, a through hole 114c formed on the base side of the protruding portion 114b, and a fitting portion 114d that is provided on the inner circumference of the opposing portion 114a and fits into the opening 113a of the water tank 11. Projecting portion 114b of ring body 114 is formed so as to face in the front-rear direction to through-hole 111b of water tank 11. Through-hole 114c is formed along the circumference and has an arc shape.

[0021] As shown in FIG. 9, blowing tool 227 has a cylindrical portion 227a, a covering portion 227b that covers through-hole 111b of water tub 11 from the front side, and a fixed portion 227c that is fixed to water tub 11. The central axis of the cylindrical portion 227a extends upward. The cross-sectional shape of the cylindrical portion 227a is flattened such that the dimension in the left-right direction is greater than the dimension in the front-rear direction. This prevents the washing machine X from becoming too large in the front-rear direction. Fixed portion 227c is fixed to water tank 11 using a fastener such as a screw, with covering portion 227b covering through-hole 111b. This allows communication between the inside of tubular portion 227a of blowing tool 227 and the space formed between covering portion 227b of blowing tool 227 and protruding portion 114b of ring body 114. The through hole 114c of the ring body 114 is located at the downstream end of the space between the covering portion 227b of the blowing tool 227 and the protruding portion 114b of the ring body 114, and forms the blowing port 28a. 8, ring body 114 is disposed opposite balancer 127 disposed at the front end of circumferential portion 121 of rotating tub 12. Therefore, blowing port 28a is located between circumferential portion 121 of rotating tub 12 and lid 113 of water tub 11.

[0022] 4, the blowing side connecting part 222 is made up of a tube made up of a rubber material etc. In this example, it is made up of a bellows-shaped tube (boot). The upper end of the blowing side connecting part 222 is connected to the outlet 214 a of the heater case 214 , and the lower end is connected to the upper side of the tubular part 227 a of the blowing tool 227 .

[0023] (1-4-3) Discharge side connection As shown in FIG. 5, discharge portion 27 is formed by tubular portion 116 of water tub 11. Opening 116a of tubular portion 116 faces rotatable tub 12 and serves as discharge port 27a. Furthermore, tubular portion 116 extends upward and is preferably linear. Opening 116a opens upward. Note that tubular portion 116 may be configured to extend left and right from peripheral portion 111 and then extend upward. In this case, opening 116a opens left and right. Furthermore, as shown in FIG. 15, tubular portion 116 may extend downward, in which case opening 116a faces downward. Cylinder portion 116 is provided on one side (right side) of water tub 11 in the left-right direction at the rear (bottom 112) side. This allows for effective use of the large space at the top of water tub 11, which has a cylindrical shape extending in the front-to-rear direction, and at the end in the left-to-right direction. Specifically, as shown in FIG. 5(b), cylinder portion 116 is provided so that circumferential portion 121 of rotatable tub 12 is located below opening 116a of cylinder portion 116 when viewed from the left-to-right direction. In other words, cylinder portion 116 is provided so that circumferential portion 121 of rotatable tub 12 exists within the projected area when projected from the top-to-bottom direction. This allows for a smaller front-to-back size of washing machine X compared to a case where the cylinder portion is provided so that the circumferential portion of the rotatable tub does not exist below the discharge outlet when viewed from the left-to-right direction (i.e., provided on the bottom side). When viewed from the left and right, the tubular portion 116 is arranged so that the bottom 122 of the rotatable tub 12 is located below the opening 116a of the tubular portion 116. In other words, when the tubular portion 116 is projected from above and below, the bottom 122 of the rotatable tub 12 is located within the projected area. This makes it easier to discharge air from inside the rotatable tub 12 through the holes 126 in the bottom 122. In this way, with the simple configuration of providing the discharge port 27a of the discharge portion 27 (the opening 116a of the tubular portion 116) on the rear end side of the rotatable tub 12, the efficiency of discharging air from inside the rotatable tub 12 can be improved. As shown in FIG. 5(b), the discharge side connecting portion 223 includes a tube 226 made of a rubber material or the like, and a duct 225 connected to an inlet 233c on the rear wall of the filter case 232. The tube 226 is made of a rubber material or the like and has an expandable bellows shape. The lower end of the tube 226 is connected to the upper side of the cylindrical portion 116. Duct 225 is disposed above tubular portion 116, and its front end is connected to case body 233 of filter case 232. This shortens the distance between exhaust port 27a and filter body 231, making it possible to prevent lint from accumulating in tube 226 and duct 225. Furthermore, because duct 225 is connected to filter case 232 above exhaust port 27a, its air path becomes linear, making it difficult for lint to become tangled in duct 225 and tube 226, and therefore making it difficult for lint to accumulate in tube 226 and duct 225. The lower end of the duct 225 is connected to a tube 226. The front end of the duct 225 is connected to a filter case 232.

[0024] (1-4-4) Positional relationship As shown in FIG. 7, inlet 28a is located forward of outlet 27a in the front-to-rear direction. This lengthens the air passage through which the hot air flows within rotatable tub 12. Furthermore, the lengthens the communication air passage connecting inlet 28a and outlet 27a, allowing for greater flexibility in the placement of hot air generator 21 and filter unit 23. Note that in this specification, when describing the position of a part, component, etc., the center of that part, component, etc. is used as the reference. As a specific example, in FIG. 7, the downstream end of casing 216 of blower 212 is located to the left of imaginary line 1L1 passing through the center in the left-to-right direction, but the description will be made such that "blower 212 is located to the left of imaginary line 1L1." In particular, the air inlet 28a is located forward of an imaginary line 1L2 that passes through the center of the rotating tub 12 in the front-to-rear direction and extends in the left-to-right direction, and the air outlet 27a is located rearward of the imaginary line 1L2. This allows the air path through which the hot air flows to be longer within the rotating tub 12, thereby widening the area through which the hot air flows. Furthermore, the longer communication air path allows for greater flexibility in the installation of the hot air generator 21 and the filter unit 23. Air inlet 28a is located between the front end (balancer 127) of rotating tub 12 and lid 113 of water tub 11, and outlet 27a is located within a projection area projected from above, with bottom 122 of rotating tub 12 positioned therein. This allows the air passage through which hot air flows within rotating tub 12 to be longer than the length of rotating tub 12 in the front-to-rear direction, thereby widening the area through which hot air flows. Furthermore, the increased length of the communication air passage allows for greater flexibility in the installation of hot air generator 21 and filter unit 23.

[0025] Air inlet 28a and outlet 27a are arranged so as not to be positioned on a single imaginary line parallel to the front-to-rear direction. That is, air inlet 28a is positioned to one side (left side) of outlet 27a in the left-right direction. In other words, air inlet 28a and outlet 27a are arranged so as not to overlap when viewed from the front, or so that an imaginary line connecting the center of air inlet 28a and the center of outlet 27a intersects with imaginary line 1L1 when viewed from above. This improves air circulation within rotating tub 12 compared to when air inlet 28a and outlet 27a are positioned on a single imaginary line parallel to the front-to-rear direction. The air inlet 28a is located on the left side of the rotation center (the imaginary line 1L1 when viewed from above) of the rotating tub 12, and the air outlet 27a is located on the right side of the rotation center. This improves the circulation of hot air. In addition, the communication air passage is longer, allowing for greater flexibility in the installation of the hot air generator 21 and the filter unit 23. Air inlet 28a is located to the left of imaginary line 1L1 and in front of imaginary line 1L2, and outlet 27a is located to the right of imaginary line 1L1 and behind imaginary line 1L2. This makes the air passage through which hot air flows inside rotatable tub 12 longer than the length of rotatable tub 12 in the front-to-rear direction, further improving the circulation of hot air. In addition, the longer communication air passage allows for greater flexibility in the installation of hot air generator 21 and filter unit 23. Furthermore, the communicating air passage, which runs from upstream to downstream, has an "L" shape (as indicated by the arrow in FIG. 7) with the right end facing from the rear to the front and then facing from the right to the left at the front end of water tank 11, and filter unit 23 and air blower 212 are arranged along the right side, and heating unit 211 and air blower 212 are arranged along the front side, respectively, thereby forming a large space on the left side in the left-right direction, behind heating unit 211 (heater case 214), and this space can be used to install a large unit such as treatment agent dispenser 18. Furthermore, the vertical space between water tank 11 and upper wall 101 is larger at the left end than at the center in the left-right direction, so that a pump for automatic dispenser 18B, water supply unit 15, etc. can be arranged therein.

[0026] Air inlet 28a is located on the left end side in the left-right direction with respect to the rotation center (imaginary line 1L1) of rotatable tub 12. As a result, the space between rotatable tub 12 and top wall 101 of housing 10 at the position of air inlet 28a is larger than the space between rotatable tub 12 and top wall 101 of housing 10 at the position of the rotation center of rotatable tub 12, and even if heater case 214 that is thick in the vertical direction is arranged around air inlet 28a, the vertical size can be prevented from increasing. Discharge outlet 27a is located on the right end side in the left-right direction with respect to the rotation center (imaginary line 1L1) of rotatable tub 12. As a result, the space between rotatable tub 12 and upper wall 101 of housing 10 at the position of discharge outlet 27a is larger than the space between rotatable tub 12 and upper wall 101 of housing 10 at the position of the central axis of rotatable tub 12, and even if filter case 232 that is thick in the vertical direction is arranged around discharge outlet 27a, an increase in the vertical size can be suppressed.

[0027] Treatment agent feed section 18 is disposed rearward of blowing section 28 and on one side (left side) in the left-right direction of filter section 23. In the left-right direction, treatment agent feed section 18 is disposed on one side of imaginary line 1L1, and filter section 23 is disposed on the other side (right side) of imaginary line 2L1. This allows the space within housing 10 to be used effectively. The blower 212 is disposed on the other side of the imaginary line 1L1 in the left-right direction, thereby creating a large space on one side in the left-right direction, in which the treatment agent dispenser 18 can be disposed.

[0028] (1-5) Other When considering the size of the washing machine X in the front-to-rear direction, it is sufficient that the discharge section 27 (discharge opening 27a) is provided on the peripheral section 111 of the water tub 11, and the positions of the hot air generating section, filter section, and blowing section (blow opening) are not particularly limited, and may be arranged as shown in FIG. 10.

[0029] (1-5-1) Example 1 As shown in Figure 10(a), in Example 1, the discharge outlet 27a is provided on the rear side of the peripheral portion 111 of the water tank 11, the filter section 23 and the treatment agent supply section 18 are arranged in a row in this order from the rear side on one side in the left-right direction (for example, the right side), and the air blower section 212, the heating section 211 and the air inlet 28a are arranged in this order from the rear side on the other side in the left-right direction (the left side). Here, when viewed from above, filter unit 23 and treatment agent feed unit 18 are located on one side (right side) of the rotation center of rotary tank 12 in the left-right direction, and air blower 212, heating unit 211, and air inlet 28a are located on the other side (left side) of the rotation center in the left-right direction. In particular, filter unit 23 and air blower 212 are arranged side by side in the left-right direction. Even with this arrangement, it is possible to prevent the size from increasing in the front-to-rear direction and to effectively utilize the space above the rotating tank 12. Furthermore, with this arrangement, it is possible to provide the manual dispensing section 18A of the processing agent dispensing section 18 in a drawer-type manner on the upper front side of the housing 10.

[0030] (1-5-2) Example 2 As shown in Figure 10(b), in Example 2, the discharge outlet 27a is provided on the rear side of the peripheral portion 111 of the water tank 11, and the filter section 23, the blower section 212, the heater section 211, and the air inlet 28a are arranged in a row from the rear side on one side in the left-right direction (for example, the right side), and the treatment agent input section 18 is arranged on the other side in the left-right direction (for example, the left side). Here, when viewed from above, filter unit 23, air blower 212, heater 211, and air inlet 28a are located on one side (right side) of the rotation center of rotary tank 12 in the left-right direction, and treatment agent feed unit 18 is located on the other side (left side) of the rotation center in the left-right direction. In particular, filter unit 23 and air blower 212 are arranged to be aligned in the front-to-rear direction. Even with this arrangement, it is possible to prevent the size from increasing in the front-to-rear direction and to effectively utilize the space above the rotating tank 12. Furthermore, with this arrangement, it is possible to provide the manual dispensing section 18A of the processing agent dispensing section 18 in a drawer-type manner on the upper front side of the housing 10.

[0031] (2) Example 2 (rear blowout) In Example 2, the positions of the air inlet 28a and the outlet 27a are different from those in Example 1, but the configurations of the hot air generating unit 21, the filter unit 23, the treatment agent supply unit 18, etc. are the same. Note that the configurations of the air inlet and the outlet are also changed due to the change in the positions of the air inlet and the outlet. In Example 2, the air inlet is provided at the rear side of one side in the left-right direction (for example, the right side), and the exhaust outlet is provided at the front side of the other side in the left-right direction (for example, the left side), and the air passage in the air passage section 42 runs from the front side to the rear side on the other side in the left-right direction (the left side), and then runs from the left side to the right side on the rear side in the front-to-rear direction. The following description will focus on the differences from the first embodiment, and the same components as those in the first embodiment will be assigned the same reference numerals and their description will be omitted.

[0032] (2-1) Hot air generating section As shown in Figures 11 and 12, the hot air generating unit 21 is arranged above the water tub 11 and includes a heating unit 211 having a heater 213 and a heater case 214, and an air blowing unit 212 having a fan 215, a casing 216, and a motor 217. The heater case 214 and the casing 216 constitute a part of the communication air passage portion 42 . 13, the heating unit 211 is disposed on one side (right side) in the left-right direction and at the rear in the front-rear direction. The blower unit 212 (motor 217) is disposed on the left side in the left-right direction, in an area from the center to the rear in the front-rear direction.

[0033] (2-2) Filter section The filter section 23 is disposed on the other side (left side) in the left-right direction with respect to the imaginary line 2L1 and on the front side in the front-rear direction, and includes a filter body 231 and a filter case 232. The filter case 232 forms a part of the communicating-air-passage section 42. The filter unit 23 is connected to the discharge unit 43 via a duct 225 and a tube 226. This allows the air in the rotating tub 12 to flow (be discharged) from the discharge unit 43 (discharge port 43a) through the tube 226 and the duct 225 to the filter case 232.

[0034] (2-3) Exhaust and intake sections The exhaust section 24 and the intake section 25 are provided in the filter case 232 . As shown in FIG. 12(a), the exhaust unit 24 exhausts air from an exhaust duct 241 extending upward from the periphery of a through-hole in a wall (for example, the right wall) 233a that constitutes one of the rooms in the filter case 232. As shown in Figure 12(b), the intake section 25 draws in air from an intake side duct 251 that extends laterally (to the left in the left-right direction) from around a through hole in the wall (e.g., the left wall) 233b that forms the other room within the filter case 232.

[0035] (2-4) Communicating air duct (communicating air duct) The communication-air-passage section 42 has an intermediate-side connection section 221 , an air-intake-side connection section 422 , and an exhaust-side connection section 423 .

[0036] (2-4-1) Intermediate connection part Intermediate connection part 221 connects an outlet on the bottom wall of filter case 232 to an inlet on the bottom wall of casing 216 so that they can communicate with each other, and is composed of case main body 233 and cover 224. When viewed from above, intermediate connection part 221 is located on one end side in the left-right direction (left end side) with respect to imaginary line L2, as shown in Figure 13. This allows for effective use of the space below filter case 232 and casing 216 and above water tank 11.

[0037] (2-4-2) Discharge side connection As shown in Fig. 12, discharge unit 43 is composed of water tub 11 and discharge tool 431. The structure of discharge tool 431 is the same as the concept of blowing tool 227 of Example 1, but the direction of air flowing inside is opposite. In other words, discharge tool 431 of Example 2 is for discharging air from inside rotatable tub 12, while blowing tool 227 of Example 1 is for blowing air into rotatable tub 12, and their functions are different. For this reason, the reference numerals of the respective parts of discharge tool 431 are the same as those of blowing tool 227. Discharger 431 has tubular portion 227a, covering portion 227b, and fixed portion 227c (see FIG. 9). Discharger 431 is fixed to water tub 11 with fixing devices such as screws, with covering portion 227b covering through-hole 111b of water tub 11. As a result, an air passage (part of the communicating air passage) communicating with filter portion 23 is formed between the inside of tubular portion 227a of discharger 431 and between covering portion 227b of discharger 431 and protruding portion 114b of ring body 114. The through-hole 114c of the ring body 114 constitutes the outlet 43a (see FIG. 13). Since the ring body 114 is arranged to face the balancer 127 provided at the front end of the peripheral portion 121 of the rotating tub 12, the discharge outlet 43a is located between the peripheral portion 121 of the rotating tub 12 and the lid portion 113 of the water tub 11.

[0038] The discharge side connecting portion 423 includes a tube 226 made of a rubber material or the like, and a duct 225 connected to the filter case 232 . The lower end of the tube 226 is connected to the upper end of the cylindrical portion 227 a of the discharge tool 431 . Duct 225 is disposed above cylindrical portion 227a, with its front end connected to case body 233 of filter case 232 and its lower end connected to tube 226. This shortens the distance between outlet 43a and filter body 231, making it possible to prevent lint from accumulating in tube 226 and duct 225.

[0039] (2-4-3) Inlet side connection Blowing section 44 is configured by tubular section 116 of water tub 11, and opening 116a of tubular section 116 faces rotatable tub 12 and serves as blowing port 44a (see FIG. 13). Cylinder portion 116 is provided at the rear of water tub 11, on one side in the left-right direction (the right side) (see FIGS. 5 and 12). In other words, when cylinder portion 116 is projected from the top-bottom direction, circumferential portion 121 of rotatable tub 12 is located within the projected area. This allows for effective use of the large space at the upper side of water tub 11, which has a cylindrical shape extending in the front-to-back directions. Cylinder portion 116 is provided so that, when viewed from the left-to-right direction, circumferential portion 121 of rotatable tub 12 is located below opening 116a of cylinder portion 116. This allows for a smaller front-to-back size of washing machine X compared to when the cylinder portion is provided so that the circumferential portion of the rotatable tub is not located below the discharge outlet when viewed from the left-to-right direction (when provided on the bottom side). When viewed from the left and right (see FIG. 5(b)), the tubular portion 116 is arranged so that the bottom 122 of the rotatable tub 12 is located below the opening 116a of the tubular portion 116. This makes it easier to blow air into the rotatable tub 12 through the holes 126 in the bottom 122. In this way, with the simple configuration of locating the opening 116a of the tubular portion 116 (blowing port 44a of the blowing portion 44) on the rear end side of the rotatable tub 12, the efficiency of blowing air into the rotatable tub 12 can be improved. As shown in FIG. 12, the blowing side connection part 422 is configured by a bellows-shaped tube made of a rubber material or the like, and its upper end is connected to the outlet 241a of the heater case 214 and its lower end is connected to the upper end of the tubular part 116.

[0040] (2-4-4) Positional relationship 13, the air inlet 44a is located further rearward than the exhaust outlet 43a in the front-to-rear direction. This lengthens the air passage through which the hot air flows within the rotating tub 12. Furthermore, the air passage connecting the air inlet 44a and the exhaust outlet 43a is longer, which increases the flexibility in installing the hot air generator 21 and the filter unit 23. In particular, the air inlet 44a is located forward of an imaginary line 2L2 that passes through the center of the rotating tub 12 in the front-to-rear direction and extends in the left-to-right direction, and the air outlet 43a is located rearward of the imaginary line 2L2. This allows the length of the air passage through which the hot air flows within the rotating tub 12 to be increased, thereby widening the area through which the hot air flows. Furthermore, the increased length of the communication air passage allows for greater flexibility in the installation of the hot air generator 21 and the filter unit 23. The outlet 43a is located between the front end (balancer 127) of the rotating tub 12 and the lid 113 of the water tub 11, and the air inlet 44a is located within a projection area projected from above, with the rear end of the circumferential portion 121 and the bottom portion 122 of the rotating tub 12 located therein. This allows the air path through which the hot air flows within the rotating tub 12 to be longer than the length of the rotating tub 12 in the front-to-rear direction, thereby widening the area through which the hot air flows. Furthermore, the longer communication air path allows for greater flexibility in the installation of the hot air generator 21 and the filter unit 23.

[0041] The air inlet 44a and the outlet 43a are arranged so as not to be positioned on a single imaginary line parallel to the front-to-rear direction. That is, the air inlet 44a is positioned to one side (left side) of the outlet 43a in the left-right direction. In other words, the air inlet 44a and the outlet 43a are arranged so as not to overlap when viewed from the front, or so that an imaginary line connecting the center of the air inlet 44a and the center of the outlet 43a intersects with the imaginary line 2L1 when viewed from above. This makes the air path of the air flowing through the rotating tub 12 longer than when the air inlet and the outlet are positioned on an imaginary line parallel to the front-to-rear direction, thereby improving circulation. The air inlet 44a is located on the right side of the rotation center of the rotating tub 12 (the imaginary line 2L1 when viewed from above), and the outlet 43a is located on the left side of the rotation center. This improves the circulation of hot air. In addition, the communication air passage is longer, allowing for greater flexibility in the installation of the hot air generator 21 and the filter 23. The air inlet 44a is located to the right of the imaginary line 2L1 and behind the imaginary line 2L2, and the air outlet 43a is located to the left of the imaginary line 2L1 and ahead of the imaginary line 2L2. This makes the air passage through which the hot air flows inside the rotating tub 12 longer than the length of the rotating tub 12 in the front-to-rear direction, thereby improving the circulation of the hot air. In addition, the longer communication air passage allows for greater flexibility in the installation of the hot air generator 21 and the filter unit 23. Furthermore, the communicating air passage, which runs from upstream to downstream, is "L" shaped, running from the front to the rear of the left end of water tank 11 and then from left to right of the rear end of water tank 11, and by arranging filter unit 23 and air blower 212 along the left side and heating unit 211 and air blower 212 along the rear side, a large space is formed on the right side in the left-right direction, in front of heating unit 211 (heater case 214), and this space can be used to install a large unit such as treatment agent dispenser 18. Furthermore, the vertical space between water tank 11 and upper wall 101 is larger at both ends than at the center in the left-right direction, making it easy to arrange a pump for automatic dispenser 18B and the like.

[0042] The air inlet 44a is located on the right end side in the left-right direction with respect to the rotation center (imaginary line 2L1) of the rotatable tub 12. As a result, the space between the rotatable tub 12 and the top wall 101 of the housing 10 at the position of the air inlet 44a is larger than the space between the rotatable tub 12 and the top wall 101 of the housing 10 at the position of the rotation center of the rotatable tub 12, and even if a heater case 214 that is thick in the vertical direction is disposed around the air inlet 44a, an increase in the vertical size can be suppressed. The discharge port 43a is located on the left end side in the left-right direction with respect to the rotation center (imaginary line 2L1) of the rotatable tub 12. As a result, the space between the rotatable tub 12 and the upper wall 101 of the housing 10 at the position of the discharge port 43a is larger than the space between the rotatable tub 12 and the upper wall 101 of the housing 10 at the position of the central axis of the rotatable tub 12, and even if a filter case 232 that is thick in the vertical direction is arranged in a position around the discharge port 43a, an increase in the vertical size can be suppressed.

[0043] Treatment agent feed section 18 is disposed rearward of discharge section 43 and on one side (right side) in the left-right direction of filter section 23. In the left-right direction, treatment agent feed section 18 is disposed on one side of imaginary line 2L1, and filter section 23 is disposed on the other side (left side) of imaginary line 2L1. This allows for effective use of the space within housing 10. The blower 212 is disposed on the other side of the imaginary line 2L1 in the left-right direction, thereby creating a large space on one side in the left-right direction, in which the treatment agent dispenser 18 can be disposed.

[0044] (2-5) Other When considering the size of the washing machine X in the front-to-rear direction, it is sufficient that the discharge section (discharge outlet) is provided on the peripheral section 111 of the water tub 11, and the positions of the hot air generating section, filter section, and blowing section (blow inlet) are not particularly limited, and may be arranged as shown in FIG. 14.

[0045] (2-5-1) Example 3 As shown in Figure 14(a), in Example 3, the air inlet 44a is provided on the rear side of the peripheral portion 111 of the water tank 11, the filter section 23 and the treatment agent supply section 18 are arranged in a row in this order from the front on one side in the left-right direction (for example, the left side), and the air blower section 212, the heating section 211 and the air inlet 44a are arranged in this order from the front on the other side in the left-right direction (the right side). Here, when viewed from above, filter unit 23 and treatment agent feed unit 18 are located on one side (left side) of the rotation center of rotary tank 12 in the left-right direction, and air blower 212, heating unit 211, and air inlet 44a are located on the other side (right side) of the rotation center in the left-right direction. In particular, filter unit 23 and air blower 212 are arranged side by side in the left-right direction. Even with this arrangement, the size in the front-rear direction can be prevented from increasing, and the space above the rotating tub 12 can be used effectively.

[0046] (2-5-2) Example 4 As shown in Figure 14(b), in Example 4, the air inlet 44a is provided on the rear side of the peripheral portion 111 of the water tank 11, and the filter section 23, the air blowing section 212, the heating section 211, and the air inlet 44a are arranged in a row from the front side on one side in the left-right direction (for example, the right side), and the treatment agent feeding section 18 is arranged on the other side in the left-right direction (for example, the left side). Here, when viewed from above, filter section 23, air blower 212, heater 211, and air inlet 44a are located on one side (right side) of the rotation center of rotary tank 12 in the left-right direction, and treatment agent feed section 18 is located on the other side (left side) of the rotation center in the left-right direction. In particular, air blower 212 and filter section 23 are arranged side by side in the front-to-rear direction. Even with this arrangement, it is possible to prevent the size from increasing in the front-to-rear direction and to effectively utilize the space above the rotating tank 12. Furthermore, with this arrangement, it is possible to provide the manual dispensing section 18A of the processing agent dispensing section 18 in a drawer-type manner on the upper front side of the housing 10.

[0047] <Modification> Although the embodiments have been described, the present invention is not limited to these embodiments, and may be modified as follows, for example. Furthermore, the embodiments may be combined with each other, the embodiments and modified examples, or modified examples may be combined with each other. Furthermore, examples not described in the embodiments and modifications, and design changes within the scope of the present invention are also included in the present invention.

[0048] 1. Washing machine (1) The washing machine has a washing function, a spin-drying function, and a drying function. However, the present invention can also be applied to a dryer that has only a drying function. (2) The processing agent dispenser 18 includes a set (adjacent) of the manual dispenser 18A and the automatic dispenser 18B, but the manual dispenser 18A and the automatic dispenser 18B may be provided separately. For example, the manual dispenser may be provided in front of the blower 212. (3) The processing agent dispenser 18 includes the manual dispenser 18A and the automatic dispenser 18B arranged side by side in the front-to-rear direction, but may also be arranged side by side in the left-to-right direction. (4) The automatic dispensing unit 18B includes two automatic dispensing tanks 182, but may include three or more automatic dispensing tanks. Furthermore, although the multiple automatic dosing tanks 182 are lined up in the front-to-back direction, they may also be lined up in the left-to-right direction. Considering the space required for disposing dosing means such as pumps for automatic dosing, it is preferable that the dosing means be located at the left-to-right ends. Note that when the automatic dosing tanks are lined up in the left-to-right direction, for example, the dosing means may be located at the left-to-right ends or rear ends and connected to the automatic dosing tanks using hoses or the like. (5) The rotating tub 12 may have a plurality of holes 126 on the peripheral portion 121 as well as on the bottom portion 122, or may have a plurality of holes arranged in a mesh pattern. Rotary tub 12 may have a structure in which peripheral portion 121 has a plurality of holes and bottom portion 122 has no holes. In this case, the plurality of holes may be provided in a mesh pattern. The rotating tub 12 may have a structure in which a plurality of holes is provided in the bottom portion 122 and no holes are provided in the peripheral portion 121. In this case, the plurality of holes may be provided in a mesh pattern.

[0049] 2. Drying unit (1) In Example 1, the air blowing section 212 and the filter section 23 are arranged on the right side in the left-right direction, and the heating section 211 and the treatment agent supplying section 18 are arranged on the left side in the left-right direction, but for example, they may be arranged in a position that is reversed left-right with respect to the virtual line 1L1 in the center in the left-right direction. (2) In Example 2, the heating section 211 and the processing agent supply section 18 are arranged on the right side in the left-right direction, and the air blowing section 212 and the filter section 23 are arranged on the left side in the left-right direction, but for example, they may be arranged in a position reversed left-right with respect to the virtual line 2L1 in the center in the left-right direction. (3) The hot air generating unit 21 includes a heating unit 211 and an air blowing unit 212. Alternatively, the hot air generating unit may include a heating unit, and the air blowing unit 212 that blows air into the rotating drum 12 may be provided separately from the hot air generating unit. (4) Although the heating unit 211 is disposed downstream of the blower unit 212, it may be disposed upstream of the blower unit 212. (5) The intermediate side connection portion 221 is configured so that the air passage passes below the blower portion 212 and the filter portion 23, but it may also be configured so that the air passage passes above the blower portion 212 or passes on one side in the left-right direction (right or left). (6) Although blower 212 has an inlet in the bottom wall of casing 216, it may have an inlet in the peripheral wall. In this case, casing 216 and filter case 232 may be directly connected without using an intermediate connector. (7) The blow-in portions 28, 44 having blow-in openings 28a, 44a and the discharge portions 27, 43 having discharge openings 27a, 43a may be integrally formed with the water tank 11 (as integrally molded products) like the discharge portions 27, 43, or may be structured such that other components are fixed to the water tank 11 like the blow-in portions 28, 44, or may be structured such that they are supported by components other than the water tank 11 and extend into the water tank 11. An example of a structure extending into the water tank is, as shown in Fig. 15, a case in which tubular portion 225a of a member (duct 225 connected to filter portion 23) supported on a frame or the like extends from through-hole 111d of water tank 11 to the inside, and opening 225b of the extending portion forms outlet 27a. Note that Fig. 15 describes outlet portion 27, but the same applies to the blowing portion. In other words, the blowing section is only required to be able to blow air into aquarium 11, and includes both a form in which it is provided directly on aquarium 11 and a form in which it is provided indirectly on aquarium 11. The exhaust section is only required to be able to exhaust air from within aquarium 11, and includes both a form in which it is provided directly on aquarium 11 and a form in which it is provided indirectly on aquarium 11. (8) When exhaust outlet 27a is provided on periphery 111 of water tub 11, it is preferable that air inlet (28a) blows air mainly through the opening at the front end of rotatable tub 12. This is because when exhaust outlet 27a and the blowing inlet are provided on periphery 111, the blown air is more easily discharged between periphery 111 of water tub 11 and periphery 121 of rotatable tub 12. Similarly, when air inlet 44a is provided on circumferential portion 111 of water tub 11, it is preferable that outlet (43a) discharge air mainly through an opening at the front end of rotatable tub 12. This is because when air inlet 44a and outlet are provided on circumferential portion 111, the blown air is more easily discharged between circumferential portion 111 of water tub 11 and circumferential portion 121 of rotatable tub 12. (9) The communicating air passages 22, 42 communicate the exhaust sections 27, 43 and the blowing sections 28, 44, but the communicating air passages may include an exhaust section and a blowing section, and may be air passages that communicate the exhaust opening and the blowing opening. (10) In the first and second embodiments, a heater-type washer-dryer has been described as an example. However, a heat pump-type washer-dryer may also be used. That is, the hot air generating unit may be configured with a heat pump that circulates refrigerant so that it is compressed by a compressor, condensed by a condenser, and evaporated by an evaporator, and a blower unit. Note that, in this case, as in the first and second embodiments, it is preferable that filter unit 23 (case 232) be disposed outside the projection range of blower unit 212 in a top view so as not to overlap with blower unit 212. (11) In the first and second embodiments, the air blower 212 and the filter unit 23 are arranged so as not to overlap one another vertically. However, the air blower 212 and the filter unit 23 may be arranged so as to overlap one another vertically. For example, a filter unit corresponding to the motor 217 of the air blower 212 may be arranged on the upper surface of the casing 216. In this case, the space around the motor 217 in the casing 216 can be used effectively. (12) In the first and second embodiments, the air blower 212 and the heating unit 211 are arranged so as not to overlap one another vertically. However, the air blower 212 and the heating unit 211 may be arranged so as to overlap one another vertically. For example, a heating unit corresponding to the motor 217 of the air blower 212 may be arranged on the upper surface of the casing 216. In this case, the space around the motor 217 in the casing 216 can be used effectively. (13) In Examples 1 and 2, the casing 216 of the air blowing unit 212 and the filter unit 23 are arranged so as to overlap each other in the front-to-back direction (horizontal direction) (their heights from the installation surface are approximately the same), but they may be arranged so as not to overlap each other in the front-to-back direction. Similarly, the casing 216 of the air blowing unit 212 and the heating unit 211 are arranged so as to overlap each other in the front-to-back direction (horizontal direction) (their heights from the installation surface are approximately the same), but they may be arranged so as not to overlap each other in the front-to-back direction.
