3. Tank Drying Unit The tank drying unit 21 is provided near the center of the cover part 242 in the front-rear direction and on one side (left side) of the cover part 242 in the left-right direction.
The tank drying unit 21 includes a blowing means 111 inside the cover part 242. Thereby, quietness, irregularities in the appearance of the cover portion 242, and safety can be improved.
The tub drying unit 21 includes an air guide means 213 in the cover part 242 that blows the air sent out by the air blower 111 into the washing tub 10 from the air outlet 217. Thereby, air can be effectively sent into the washing tub 10.
The tank drying unit 21 includes an air blowing means 111 and a case 215, and the case 215 forms a guide portion (nozzle portion) that constitutes an air blowing guide means 213. Thereby, the air blow guide means 213 can be easily implemented.

The case 215 here includes a pair of plate parts 215a and a connecting plate part that connects the pair of plate parts 215a. The connecting plate portion has a pair of upper and lower connecting plate portions 215b and 215c, as shown in FIG. 3(b). Air blowing means 111 is arranged between the pair of connecting plate parts 215b and 215c. As a result, the air from the blowing means 111 passes between the pair of connecting plate parts 215b and 215c, and is blown out from the air outlet 217.
Here, since the connecting plate part 215b is located on the upper side, it is referred to as the upper connecting plate part 215b, and the connecting plate part 215c is located on the lower side, so it is referred to as the lower connecting plate part 215c for convenience.
The case 215 has a storage space that accommodates the blower 111 and a blower guide space that guides the air from the blower 111 to the outlet 217 . Since the accommodation space and the ventilation guide space are continuous, most of the air blown from the ventilation means 111 passes through the ventilation guidance space, and the air from the ventilation means 111 can be used effectively.

The upper connecting plate portion 215b has a sloped portion 215d that slopes in accordance with the slope of the inner peripheral wall portion 242b of the cover portion 242, and a flat portion 215e that extends outward in the left-right direction from the upper end of the sloped portion 215d. Here, the inclined portion 215d is referred to as an upper inclined portion 215d for convenience, and the flat portion 215e is referred to as an upper flat portion 215e for convenience.
The lower connecting plate portion 215c includes an inclined portion 215f that is located on the outer side in the left-right direction with respect to the upper inclined portion 215d and that faces the air outlet 217 side portion of the upper inclined portion 215d, and a sloped portion 215f that is located on the outer side in the left-right direction with respect to the upper inclined portion 215d. It has a flat portion 215g extending outward. Here, the inclined portion 215f is referred to as a lower inclined portion 215f for convenience, and the flat portion 215g is referred to as a lower flat portion 215g for convenience.

The case 215 is provided on the cover portion 242 so that the upper inclined portion 215d is flush with the inner circumferential wall portion 214b of the cover portion 242 around the tank drying unit 21. Thereby, the design of the cover part 242 can be maintained even though the tank drying unit 21 is provided.
The case 215 is attached to the cover part 242 so that the air outlet 217 is located on the inner peripheral side of the cover part 242. Thereby, the washing tub 10 can be efficiently dried.

The air outlet 217 is formed by the lower ends of a pair of plate portions 215a, an upper inclined portion 215d, and a lower inclined portion 215f, and has a rectangular shape that is long in the front-rear direction.
The accommodation space includes a pair of plate portions 215a, an upper flat portion 215e, and a lower flat portion 215g.
The ventilation guide space is a space formed by a pair of plate parts 215a, an upper connecting plate part 215b, and a lower connecting plate part 215c, excluding the accommodation space, and is a space formed by these parts. A nozzle portion is formed.
The distance between the upper connecting plate part 215b and the lower connecting plate part 215c that constitute the air blowing guide space becomes smaller toward the outlet 217 on the downstream side. That is, the nozzle portion has a tapered shape that becomes narrower toward the outlet 217.
In this way, the air blowing means 111 is housed on the upstream side (outer circumferential side) within the case 215, and the user can be prevented from coming into contact with the air blowing means 111. By forming the nozzle part into a tapered shape, the air from the blowing means 111 can be blown out efficiently. In addition, the flow rate of air from the blowing means 111 can be increased and the air can be blown out, so that the drying of the washing tub 10 can be accelerated. Similarly, water splashes scattered during washing can be prevented from entering the air blower 111 side, and water splashes that have entered the nozzle part can also be caused to flow downward along the upper slope portion 215d or the lower slope portion 215f.
Although the air outlet 217 is directed downward, the air guide space formed by the upper inclined portion 215d and the lower inclined portion 215f is directed inward (towards the rotating shaft of the washing tub) as it moves downward. Because it is tilted, air is blown into the inside of the washing tub.

Further, the lid body 1153 is configured to be detachable from the tank body 1151, and may further include an openable/closeable lid portion for pouring the liquid agent into the tank body 1151.
Although one filter 1017 is provided in one tank body 1151 here, a plurality of filters 1017 may be provided.
The filter 1017 will be explained below.

(2) Filter (2-1) Common structure The filter 1017 is arranged in the liquid agent tank 1015 so that the liquid agent passes through the filter 1017 when the liquid agent in the liquid agent tank 1015 is supplied to the washing tub. . In FIG. 6A, the liquid agent flows from the front side (the left side in FIG. 6A) to the rear side, and the filter 1017 is disposed on the discharge port 1154 side of the liquid agent tank 1015. The filter 1017 is provided to cover the discharge port 1154, and here, it is provided so as to lean against the bottom wall and rear wall of the liquid agent tank 1015. Thereby, it is possible to restrict dust and the like from flowing into the discharge port 1154.
The filter 1017 has a dogleg shape or a similar shape that is bent midway in the vertical direction, but it may have a flat shape.
In addition, in the filter 1017, in the direction in which the liquid agent passes (direction from the front side to the rear side), the upstream side is the front side, and the downstream side is the back side.

The filter 1017 is made of, for example, a molded product made of resin. The filter 1017 is plate-shaped and has a lattice-like structure in which a lattice extends diagonally along the surface direction of the filter 1017 .
Note that the lattice shape includes a shape in which a plurality of lattices extend parallel or substantially parallel (also referred to as a parallel lattice), a plurality of first lattices extending parallel or substantially parallel to a first direction, and a plurality of first lattices extending parallel or substantially parallel to a first direction. There is a shape in which a plurality of second lattices extending parallel or substantially parallel to different second directions intersect (also referred to as a crossed lattice).
The filter 1017 has one or more filter sections 1170 having a lattice structure, as shown in FIGS. 6(b) and 6(c). Here, it has four filter sections 1170a, 1170b, 1170c, and 1170d. Note that if there is no need to distinguish between the four filter sections, the code will be described as "1170".

The filter 1017 has a frame portion 1171 and a connecting portion 1172. The frame portion 1171 here has a rectangular shape or a shape similar to a rectangular shape, and the connecting portion 1172 has a shape that connects the middle portion of the frame portion 1171.
The four filter parts 1170 are formed in a region surrounded by the frame part 1171 and the connecting part 1172, and the connecting part 1172 can also be said to be a boundary part between adjacent filter parts 1170.
Specifically, the frame portion 1171 includes a pair of vertical frame portions 1171a extending in the vertical direction or a direction along the vertical direction, and a pair of horizontal frame portions 1171a extending in the horizontal direction orthogonal to the vertical direction or in a direction along the horizontal direction. It has a frame portion 1171b. Thereby, the filter 1017 can be reinforced.
The connecting portion 1172 has a horizontal connecting portion 1172a that connects the middle portions of the pair of vertical frame portions 1171a, and a vertical connecting portion 1172b that connects the middle portions of the pair of horizontal frame portions 1171b, and has a cross (“+”) shape. ) shape. Note that the vertical frame portion 1171a and the vertical connecting portion 1172b are bent at about 20 degrees at the horizontal connecting portion 1172a. This allows the area of the filter section 1170 to be increased.
Note that the connecting portion 1172 has a rib portion 1172c projecting to the back side, as shown in FIG. 6(c).
At least one of the width (vertical dimension) of the horizontal connecting portion 1172a and the width (horizontal dimension) of the vertical connecting portion 1172b of the connecting portion 1172 is equal to the width of the gratings 1177, 1178 (the direction in which the gratings extend and the front and back directions). (dimension perpendicular to).

The filter section 1170 (lattice-like structure) has a plurality of (for example, "2") lattice sections 1173 and 1174. This results in a cross-lattice structure.
(2-2) Multiple lattice parts (2-2-1) Example 1
The two lattice sections are a front lattice section 1173 located on the front side and a back lattice section 1174 located downstream (on the back side) of the front lattice section 1173. The front side lattice part 1173 and the back side lattice part 1174 are provided so as to intersect with each other. That is, when the filter section 1170 is viewed from the front and back directions, as shown in FIGS. A plurality of back side lattices 1178 forming the lattice extend in the second direction, and the front side lattice 1177 and the back side lattice 1178 intersect.
In addition, in the figure, the front side lattice part 1173 and the back side lattice part 1174 are given a symbol such as "a" to correspond to the four filter parts 1170a, 1170b, 1170c, and 1170d.

(2-2-2) Example 2
In example 1, the front side lattice part 1173 and the back side lattice part 1174 are such that the back surface of the front side lattice part 1173 is connected to the surface of the back side lattice part 1174, and they do not overlap in the front and back direction, but two (plural) lattice parts , may overlap in the front and back directions.
In other words, the plurality of lattice sections in Example 2 include a first lattice section made up of a plurality of first lattices inclined in a first direction, and a second lattice section made up of a plurality of second lattices inclined in a second direction. , the first lattice section and the second lattice section intersect within the same plane, and one of the first lattice section and the second lattice section protrudes toward the upstream side and extends in an oblique direction. It may also have a stretched rib portion.
In other words, the back surface of the first lattice section and the back surface of the second lattice section are flush with each other, the first lattice and the second lattice intersect, and the extending rib of one of the lattice sections of the first lattice and the second lattice section This is the case where the surface of one section is located upstream of the surface of the other grid section. Note that the form of Example 2 is modified such that the first lattice part and the second lattice part intersect so that the front surface and the back surface are flush with each other, and the surface of one of the lattice parts of the first lattice part and the second lattice part is There may also be a rib portion that protrudes toward the front side.

(2-2-3) Example 3
In Example 3, the plurality of lattice sections of Example 3 include a first lattice section made up of a plurality of first lattices inclined in a first direction, and a first lattice section made up of a plurality of second lattices inclined in a second direction. 2 lattice parts, and an intermediate portion of the first lattice part in the front and back direction may intersect with the second lattice part.
In other words, the case is such that the back surface of the first lattice section is located on the back side of the second lattice section, and the surface of the first lattice section is located on the front side of the second lattice section.

(2-3) Direction of the lattice The extending direction of the lattice will be explained using Example 1 of "(2-2) Multiple lattice parts" above, and Example 2 of "(2-2) Multiple lattice parts" The same applies to Example 3 as well.

(2-3-1) Example 4
As shown by the thick line in FIG. 8A, the front grating 1177A of the front grating parts 1173a and 1173b in the filter parts 1170a and 1170b located on one side in the horizontal direction perpendicular to the front and back directions is With reference to the vertically connecting portion 1172b located between the filter portions 1170c, 1170d (front side grid portions 1173c, 1173d) located on the other side, the height becomes lower toward the vertically connecting portion 1172b from one side.
The front grating 1177B of the front grating portions 1173c, 1173d in the filter portions 1170c, 1170d located on the other side in the horizontal direction (horizontal direction) orthogonal to the front/rear direction is, as shown by the thick line, on the other side with respect to the vertical connection portion 1172b. It becomes lower as it goes from the side toward the vertical connection portion 1172b.
That is, the front side lattice portion 1173 has first front side lattice portions 1173a, 1173b which become lower as they go from one side in the horizontal direction toward the vertical connection portion 1172b, and as they go from the other side in the horizontal direction toward the vertical connection portion 1172b. It has second front side lattice portions 1173c and 1173d that are lowered.
In other words, when the front side lattice portion 1173 is viewed from the front side, the front side lattice 1177 has an inverted "V" shape.
When the grid is formed in the above direction, as the amount of liquid decreases, the dirt in the tank flows along the front grids 1177A, 1174B of the front grid section 1173, approaching the vertical connection portion 1172b. This can prevent dust from accumulating on the side of the front grid section 1173 that is remote from the vertical connection section 1172b. Therefore, the side of the filter portion 1170 remote from the vertically connected portion 1172b can be made less likely to be clogged with dirt or the like.
Further, although there is a tendency for dust to accumulate on the side of the vertically connected portion 1172b, since no through hole is provided in the vertically connected portion 1172b, the influence of the accumulated dust is small.

(2-3-2) Example 5
As shown in FIG. 8(b), the filter 4017 has filter parts 4170a, 4170b, 4170c, and 4170d.
The front side lattice 4177A of the front side lattice parts 4173a and 4173b located on one side in the horizontal direction (horizontal direction) perpendicular to the front and back direction is, as shown by the thick line in FIG. It becomes lower as it goes from one side toward the vertical connection portion 4172b.
The front side lattice 4177B of the front side lattice parts 4173c and 4173d located on the other side in the lateral direction (horizontal direction) perpendicular to the front and back direction is connected from the vertical connection part 4172b to the other side with the vertical connection part 4172b as a reference, as shown by the thick line. It gets lower as you go.
That is, the front side lattice part 4173 has first front side lattice parts 4173a, 4173b and second front side lattice parts 4173c, 4173d, which become lower from one side to the other side in the lateral direction.
In other words, when the front grid portion 4173 is viewed from the front side, the front grids 4177A and 4177B all extend in the same direction.
When the front grids 4177A, 4177B are formed in the above direction, the garbage in the tank flows from one side to the other side along the front grids 4177A, 4177B of the front grid section 4173. This can prevent dust from accumulating on one side of the front grid section 4173 in the lateral direction. Therefore, the area on one side of the filter section 4170 can be made less likely to be clogged with dirt or the like.
In FIG. 8, the grid is shown thick for convenience so that the orientation of the grid can be seen.

(2-4) Angle of the lattice The angle of the lattice part will be explained using Example 1 of "(2-2) Multiple lattice parts" and Example 4 of "(2-3) Direction of lattice" above. The same applies to Examples 2 and 3 of "(2-2) Plural lattice parts" and Example 5 of "(2-3) Direction of lattice."
The angle of the front grating 1177 may be 45 degrees with respect to the lateral (horizontal) direction, as shown by the thick line in FIG. 7(b).
The angle of the front grating 2177 may be greater than 45 degrees with respect to the lateral direction, for example, 75 degrees, as shown by the bold line in FIG. 7(a).
The angle of the grating 3177 may be less than 45 degrees with respect to the lateral direction, for example, 15 degrees, as shown by the bold line in FIG. 7(c).
The angle of the lattice of the lattice part where the surface is located closest to the front side is preferably 45 degrees from the viewpoint of the opening area of the lattice structure, and from the viewpoint of retention (accumulation condition) of dirt etc. in the vertical connection part, An angle larger than 45 degrees is preferable because the angle becomes jagged. Further, from the viewpoint of resin molding, an angle larger than 45 degrees is preferable since the holes between the lattices are crushed.
In FIG. 7, the grid is shown thick for convenience so that the orientation of the grid can be seen.

4. Lattice The diagonally extending lattice extends linearly, but may also extend curvedly, or may include a lattice that extends linearly and a lattice that extends curvedly.
Although the lattice has a constant cross-sectional shape perpendicular to its extending direction, it does not have to be constant. For example, it may become thinner from the top to the bottom.

5. Others The lid portion 1014c is configured such that the front side is lifted up and opened to the rear side with the left and right direction as a rotation axis, but the lid portion 1014c is not limited to this. It may be configured to open and close with the front-rear direction as the rotation axis. Specifically, the left side may be raised and opened around the right rotation axis, or the right side may be raised and opened around the left rotation axis.
The lid portion 1014c is not limited to one for the plurality of liquid tanks 1015, and may be divided into two or more, regardless of whether the left-right direction is the rotation axis and the front-back direction is the rotation axis.
