More specifically, the flow path member 101 forms a plurality of independent paths connected from the water supply valves 10a, 10b, and 10c to the supply destination.

The water supplied to the boxes 110, 111, 112, and 113 of the manual injection unit 56 flows into the washing tub 4 together with the contained detergent.

Next, the structure of the manual injection unit 56 will be described in more detail with reference to FIGS. 3 to 6 . FIG. 4 is a perspective view of the manual insertion unit 56. FIG. 5 is a cross-sectional view showing a state in which the cartridge 113 and the flow path members 115 and 116 have been removed from the manual input unit 56 . FIG. 6 is a perspective view of the manual insertion unit 56.

As shown in FIG. 3 , the manual insertion unit 56 includes a main body 114 . The main body 114 is a member held in the unit box 100 so as to be pullable in the front-rear direction L.

As shown in FIG. 4 , the main body portion 114 accommodates the flow path members 115 and 116 and the box 113 (hereinafter, referred to as the tablet box 113 ). The flow path members 115 and 116 and the tablet box 113 are detachably accommodated in the main body 114 .

As shown in FIG. 5 , the body portion 114 forms boxes 110 , 111 , and 112 . As described above, box 110 (hereinafter, referred to as softener box 110) contains softener, box 111 (hereinafter, referred to as bleach box 111) contains liquid bleach, and box 112 (hereinafter, referred to as powder detergent box 112) ) holds powder lotion.

In the main body 114, the softener box 110 and the bleach box 111 are arranged in an array in the width direction K. The powder detergent box 112 has an insertion space 117 formed on the front sides L1 of the boxes 110 and 111 and a flow path 118 extending between the softener box 110 and the bleach box 111 . The flow path 118 is connected to the input space 117 . The flow path 118 has an outflow port (not shown) that extends from the connection position with the input space 117 toward the rear side L2 to the discharge port 119 ( FIG. 11A ), and is connected to the washing tub 4 at the lower end. The flow path 118 is defined by the outer side walls of the softener box 110 and the bleach box 111 and the bottom surface of the main body 114 (inclined surface 118b shown in FIG. 6 ).

The upper portions of the boxes 110 and 111 form input openings 110a and 111a, and the upper portion of the input space 117 forms an input port 117a.

The upper part of the flow path 118 also has an opening, and the tablet box 113 is arranged in the upper part of the flow path 118 . That is, the tablet box 113 is arranged between the boxes 110 and 111 . The tablet box 113 in this embodiment is arranged adjacent to the input space 117 without leaving any space. In addition, since the tablet box 113 only needs to be adjacent to the input space 117, that is, to be arranged nearby, the tablet box 113 may be arranged adjacent to the input space 117 with a gap provided therebetween.

An insertion opening 113a is formed in the upper part of the tablet box 113, and tablets J are inserted into the insertion opening 113a (Fig. 4). When the tablet box 113 is arranged in the main body 114, the input port 113a is arranged between the input port 110a and the input port 111a arranged in the width direction K.

As shown in FIG. 6 , the bleach box 111 has an accommodating place 78 for accommodating liquid bleach and a liquid discharge channel 74 . The liquid discharge flow path 74 has a U-shape that extends upward from the suction port 74 a and is folded back at the upper part of the bleach box 111 to be connected to the bottom surface 78 a of the accommodation 78 . The liquid discharge flow path 74 sucks the softener from the suction port 74a and discharges the softener from the discharge opening 74b formed in the bottom surface 78a of the accommodating place 78.

Returning to FIG. 5 , the softener box 110 has an accommodating place 77 for accommodating softener and a liquid discharge channel 73 . The liquid discharge channel 73 has a U-shape like the liquid discharge channel 74 .

The flow path members 115 and 116 are arranged so as to cover the liquid discharge flow paths 73 and 74 of the cartridges 110 and 111, respectively. When the flow path members 115 and 116 cover the liquid discharge flow paths 73 and 74 , a flow path is formed between the flow path members 115 and 116 and the liquid discharge flow paths 73 and 74 . With this structure, when the liquid level in the boxes 110 and 111 exceeds a predetermined height, water and liquid can flow out of the boxes 110 and 111 beyond the tops of the liquid discharge channels 73 and 74 . That is, until the water supply valve 10a or the water supply valve 10b is opened to supply water to the box 110 or the box 111 and the liquid level exceeds a predetermined height, the lotion or softener will not flow out of the boxes 110 and 111 and can be kept in the box. Within 110, 111. In addition, after the water supply valve 10a is closed to stop water supply, the liquid and water in the bleach box 111 will also be discharged from the discharge opening 74b due to the siphon phenomenon in the flow path between the flow path member 116 and the liquid discharge channel 74. spit out. Accordingly, water can be prevented from remaining in the bleach box 111 . The same applies to the inside of the softener box 110 .

The tablet box 113 is a member that accommodates a water-soluble solid agent used in one sterilization washing course. Solid agents are solid or hollow solids. For example, a solid agent is a solid object formed by compressed and aggregated powder. The solid agent can also be called a solid treatment agent. In Embodiment 1, tablet J is demonstrated as an example of a solid agent.

Here, tablet J contains a component that exhibits bactericidal performance. Tablet J contains water-soluble ingredients. Although it has a certain shape before being supplied with water, it will break down into smaller pieces and dissolve in water after being sprinkled with water.

In Embodiment 1, tablet J contains sodium dichloroisocyanurate as a bactericidal component. Regarding the constituent materials of Tablet J, Tablet J may also contain components that generate other hypochlorous acid. Tablet J may also contain ingredients that react with water to form foam.

Regarding the shape of the tablet J, the tablet J may also have a shape that is movable to a predetermined position in the tablet box 113 , for example, has a peripheral shape or contour that can be rolled and moved. In Embodiment 1, the tablet J has a disk shape with a diameter D0 larger than a thickness T0 (Fig. 12A, Fig. 12B).

The tablets J put into the tablet box 113 may be specific tablets J envisaged to be used by the manufacturer of the washing machine 51 . For example, Tablet J is one or a plurality of specified types of Tablet J. For example, the type of tablet J is selected from the catalog or list stored in the control unit C.

As shown in FIG. 6 , the tablet box 113 is fixed by being hung on the side walls of the boxes 110 and 111 defining the flow path 118 . Specifically, the tablet box 113 has a hooking portion 122 that protrudes in the width direction K and is hooked on the upper portion of the side walls of the boxes 110 and 111 .

Next, the tablet box 113 will be described in more detail with reference to FIGS. 7 to 11B . FIG. 7 is a perspective view of the tablet box 113. As shown in FIG. FIG. 8 is a perspective view of the tablet box 113 in an open state. FIG. 9 is a cross-sectional view of the tablet box 113 along the width direction K. As shown in FIG. FIG. 10A is a cross-sectional view of the tablet box 113 along the front-rear direction L. FIG. FIG. 10B is a cross-sectional view of the tablet box 113 in the drainage space R12 along the width direction K. FIG. FIG. 11A is a cross-sectional view of the manual insertion unit 56 along the front-rear direction L. FIG. 11B is a cross-sectional view of the manual insertion unit 56 along the width direction K. As shown in FIG.

As shown in FIGS. 7 and 8 , the tablet box 113 is an openable and closable member and has a first side wall 140 and a second side wall 142 . The first side wall 140 and the second side wall 142 are connected to each other through the rotation axis X. The posture of the tablet box 113 can be changed between the posture in which the first side wall 140 and the second side wall 142 face each other (Fig. 7) and the posture in which the first side wall 140 and the second side wall 142 are along each other (Fig. 8). Specifically, the second side wall 142 is rotatable around the rotation axis X along the peripheral wall 141 (see arrow G). By rotating the second side wall 142 to release the opposing state, the inner wall of the tablet box 113 becomes easier to access, making it easier to clean or maintain the inner wall of the tablet box 113 .

As shown in FIG. 8 , the first side wall 140 is formed with a mesh 132 a penetrating in the thickness direction (width direction K), and the second side wall 142 is formed with a mesh 132 c penetrating in the thickness direction (width direction K). The dissolved tablet J flows out from the mesh holes 132a and 132c together with water and is supplied to the washing tank 4.

The first side wall 140 further forms a mesh 132b on the front side L1 of the mesh 132a.

The first side wall 140 is provided with a peripheral wall 141 and a narrow portion 137 . The second side wall 142 is provided with a narrow portion 137, a holding portion 138, and a water removal portion 81.

The peripheral wall 141 is connected to the outer peripheral portion of the first side wall 140 and forms the front surface 139 of the tablet box 113 and the bottom wall portion 136 extending in the front-rear direction L (horizontally). The bottom wall portion 136 below the insertion port 113a forms a water supply position K2 for supporting the inserted tablet J.

Here, the water supply position K2 refers to the position of the bottom wall portion 136 where the tablet J is placed when water is supplied. Therefore, the water supply position K2 has a larger shape than the tablet J. Specifically, the dimension L in the front-rear direction of the water supply position K2 (corresponding to the dimension D4 of the accommodating space R11 to be described later) is larger than the diameter D0 of the tablet J (Fig. 10A). The water supply position K2 may be a position assumed to be reached after the tablet J has been inserted. The water supply position K2 is an area having a long vertical shape in the front-rear direction L in a plan view. The water supply nozzles 12 and 13 of the flow path member 101 are formed above the water supply position K2. The water supply position K2 can also be set directly below the water supply nozzles 12 and 13.

In the peripheral wall 141, the front face 139 and the bottom wall portion 136 are smoothly connected. The corner between the front face 139 and the bottom wall 136 has a curvature. Therefore, compared with a case where the curvature of the corner portion is small, fragments of the tablet J become less likely to be clogged in the corner portion, and dissolution of the tablet J can be suppressed.

The narrow portion 137 is a wall portion protruding in the width direction K from the inner wall of the side walls 140 and 142 toward the opposite side wall. The narrow portion 137 prevents the tablet J and large fragments generated from the tablet J from leaving the water supply position K2 and flowing into the depth of the tablet box 113 . Larger debris means debris having a size that cannot pass through the mesh holes 132a, 132c and blocks the mesh holes 132a, 132c. This structure prevents large debris from adhering to the mesh holes 132a and 132c, thereby maintaining the drainage properties of the mesh holes 132a and 132c.

As shown in FIG. 9 , the narrow portion 137 provided on the first side wall 140 and the narrow portion 137 provided on the second side wall 142 have a gap R4 along the width direction K. The distance R4 becomes smaller toward the bottom wall 136 . Therefore, the structure of the narrow portion 137 can more reliably restrict the passage of fragments of the larger and heavier tablet J.

The holding portion 138 further projects in the width direction K from the narrow portion 137 . The holding part 138 connects the narrow part 137 provided on the first side wall 140 and the narrow part 137 provided on the second side wall 142 . Therefore, even in the case where the tablet J becomes thinner than the interval R4, the tablet J can be restricted from leaving the water supply position K2.

As shown in FIG. 10A , the holding portion 138 and the narrowing portion 137 together have the function of accommodating the tablet J in the water supply position K2. The holding part 138 and the narrow part 137 restrict the movement of the tablet J to accommodate the tablet J in a certain space. The holding part 138 and the narrow part 137 have the function of partitioning the storage space R11 which accommodates the tablet J, and the drainage space R12 which restricts the entry of the tablet J.

The holding portion 138 is upwardly spaced away from the bottom wall portion 136 and has a gap R3 between the holding portion 138 and the bottom wall portion 136 . Therefore, the accommodating space R11 and the drainage space R12 are also connected through the gap R3 below the holding part 138 . By providing the interval R3, when the water level is low, the water supplied to the water supply position K2 can flow into the drainage space R12. While restricting the entry of the tablet J into the drainage space R12, the inflow of water into the drainage space R12 is promoted, so that the water passes through the mesh holes 132a and 132c and is drained.

The accommodating space R11 and the drainage space R12 also communicate with each other above the holding part 138 . Therefore, when the water level becomes high, while restricting the entry of the tablet J into the drainage space R12, the inflow of water into the drainage space R12 is further promoted, so that more water is drained through the mesh holes 132a and 132c.

The water flowing into the drainage space R12 contains the dissolved tablet J. In this way, the accommodating space R11 is a space for accommodating and dissolving the tablet J, and the drainage space R12 is a space for discharging the tablet J dissolved in the accommodating space R11 from the mesh holes 132a and 132c.

Here, when focusing on the space where drainage is mainly performed is the drainage space R12, the drainage space R12 is a space in which mesh holes 132a and 132c are formed. On the other hand, the accommodating space R11 is a space in which the mesh 132b is formed.

Mesh holes 132a and 132c are formed in substantially the entire surfaces of the side walls 140 and 142 in the drainage space R12. The area of the mesh 132a may be 60% or more and not more than 90% of the area of the first side wall 140 in the drainage space R12, and the area of the mesh 132c may be 60% of the area of the second side wall 142 in the drainage space R12. Above and below 90%. The side walls 140 and 142, together with the mesh holes 132a and 132c, also have reinforcing parts 144 for maintaining the strength of the tablet box 113.

The mesh 132b is formed only in a part of the first side wall 140 in the accommodation space R11. For example, the mesh 132b is formed only in the lower portion of the first side wall 140 . The area of the mesh 132b may be 10% or more and 50% or less of the area of the first side wall 140 in the accommodation space R11. In addition, the area of mesh 132b is smaller than the area of mesh 132a or mesh 132c. For example, the area of the mesh 132b is 25% or less of the area of the mesh 132a or the mesh 132c. The opening area of the mesh 132b may also be smaller than the opening area of the mesh 132a or the mesh 132c.

The height of the apex of the mesh 132b from the bottom wall 136 toward the input port 113a is formed to be lower than the height of the apex of the mesh 132a or the mesh 132c. The height of the apex of the mesh 132b may be less than half of the diameter D0 of the tablet J.

In the accommodation space R11, since the mesh 132b is formed only in the first side wall 140, water becomes easy to accumulate in the accommodation space R11. With this structure, Tablet J becomes easily soluble. On the other hand, in the drainage space R12, mesh holes 132a and 132c are formed in the side walls 140 and 142 respectively. With this structure, water can be drained from the side walls 140 and 142 on both sides, and water can be suppressed from overflowing from the input port 113 a of the tablet box 113 . Furthermore, by ensuring a drainage path passing through the drainage space R12, residual water can be suppressed in the accommodation space R11.

As shown in FIG. 10B , the mesh holes 132 a and 132 c of the side walls 140 and 142 on both sides are inclined relative to the vertical. The mesh holes 132a and 132c of the side walls 140 and 142 form a V-shaped cross section, and the distance between the mesh holes 132a of the first side wall 140 and the mesh holes 132c of the second side wall 142 becomes narrower downward. With this structure, in addition to the narrow portion 137, the mesh holes 132a and 132c themselves function as narrow portions to suppress the entry of the tablet J into the drainage space R12. The inclination angle of the mesh holes 132a and 132c may be equal to the inclination angle of the narrow portion 137.

On the outside of the tablet box 113, the mesh 132a faces the outer wall 110c of the softener box 110, and the mesh 132c faces the outer wall 111c of the bleach box 111. A gap R4 is formed in the width direction K between the mesh hole 132a and the outer side wall 110c, and a gap R6 is formed in the width direction K between the mesh hole 132c and the outer side wall 111c. Water is drained from the tablet box 113 through the intervals R4, R6. The intervals R4 and R6 become larger downward due to the inclination of the mesh holes 132a and 132c. Therefore, drainage properties of the mesh holes 132a and 132c can be ensured even in the lower portion of the tablet box 113 where many fragments of the tablet J are accumulated.

The mesh 132b is arranged vertically and in contact with the outer side wall 110c of the softener box 110 (Fig. 16A). The mesh 132b is away from the outer side wall 111c of the bleach box 111.

The difference between the accommodating space R11 and the drainage space R12 will be described from another perspective. As shown in FIG. 10A , when focusing on the space into which the tablet J can be inserted is the accommodation space R11 , the space formed directly below the insertion opening 113 a is the accommodation space R11 , and the space offset from the insertion opening 113 a is Drainage space R12. A part of the drainage space R12 faces the input port 113a.

The insertion port 113a is formed extending in the front-rear direction L from the front surface 139 of the tablet box 113. The input port 113a may have a longitudinal shape when viewed from above. That is, the width D2 (Fig. 9) of the input port 113a may be smaller than the length D3 in the front-rear direction L of the input port 113a. Therefore, the accommodating space R11 may have a longitudinal shape when viewed from above.

The dimension D4 of the accommodating space R11 in the front-rear direction L is smaller than the dimension D3 of the input port 113a in the front-rear direction L, and is substantially equal to the dimension D3. The dimension D4 in the front-rear direction L of the accommodating space R11 may be 0.7 times or more and 1.2 times or less the dimension D3.

The dimension D6 of the drainage space R12 in the front-rear direction L is larger than the dimension D4 of the accommodation space R11 in the front-rear direction L. For example, the size D6 is 1 time or more and 3 times or less the size D4. In addition, the volume of the drainage space R12 may also be larger than the volume of the accommodation space R11.

The dimension D4 of the accommodation space R11 in the front-rear direction L is substantially equal to the dimension D5 of the tablet box 113 in the up-down direction. The dimension D5 is the distance in the up-down direction from the bottom wall 136 to the input port 113a. With this structure, the tablet box 113 can be space-saving.

Returning to FIG. 7 , the first side wall 140 has a hooking portion 122 hooked on the edge of the insertion port 110 a of the box 110 , and the second side wall 142 has a hooking portion 122 hooked on the edge of the insertion port 111 a of the box 111 . By hanging the hooking part 122 on the boxes 110 and 111, the tablet box 113 will be supported by the main body part 114 (Fig. 6). The hooking portion 122 has a restricting portion 123 that protrudes further in the width direction K relative to the hooking portion 122 . The restriction part 123 partially covers the insertion openings 110a and 111a of the boxes 110 and 111 (Fig. 6). The restriction portion 123 is formed on the edge portion 124 facing each other in the front-rear direction L to prevent the tablet J accidentally inserted into the box 110 from moving toward the rear side L2.

As shown in FIG. 11A , when the hooking portion 122 is hooked to the boxes 110 and 111 and the tablet box 113 is arranged on the main body 114 , the tablet box 113 is arranged above the bottom surface of the flow path 118 . The flow path 118 is a flow path for discharging the powder detergent and the tablet J from the discharge port 119 and supplying them to the washing tub 4 , that is, it is a non-liquid supply flow path. When the tablet box 113 is accommodated in the main body 114, the accommodating space R11 is arranged on the front side L1 of the drainage space R12, that is, closer to the input space 117 than the drainage space R12.

The bottom surface of the flow path 118 is constituted by an inclined surface 118b that is inclined downward relative to the horizontal direction toward the rear side L2. In Embodiment 1, the inclined surface 118b is inclined downward toward the rear side L2 with respect to the bottom wall portion 136 extending horizontally and linearly. The inclination angle of the inclined surface 118b may be fixed, or may be changed along the way of the inclined surface 118b.

The bottom wall 136 of the tablet box 113 is arranged to cover the entire surface with a gap D1 upward from the inclined surface 118b. The distance D1 is the distance in the up-down direction (vertical distance) between the bottom wall 136 of the tablet box 113 and the inclined surface 118b. Since the inclined surface 118b is inclined relative to the bottom wall portion 136, the distance D1 gradually increases toward the rear side L2. In other words, the bottom wall portion 136 and the inclined surface 118b move away from each other as they enter the rear side L2.

Here, the bottom wall portion 136 does not include a corner portion with curvature that constitutes the lower end of the front surface 139 of the tablet box 113 .

The distance D1 is smallest at the front surface 139 of the tablet box 113 located near the connection portion P between the input space 117 and the flow path 118 . When considering that water flows from the input space 117 toward the flow path 118 , the distance D1 is the smallest in the inlet of the flow path 118 located in the connection portion P. The connection portion P is a portion where the input space 117 and the flow path 118 are connected to each other, and is a portion where the cross-sectional area of the flow path is narrowed relative to the input space 117 , for example. Further downstream than the connecting portion P, the flow path cross-sectional area may be substantially constant up to the discharge port 119 .

When water is supplied to the input space 117, the liquid level S1 of the water rises (see arrow V1). When the water supply amount is large, the liquid level S1 becomes higher than the front surface 139 of the tablet box 113 .

A water removal part 81 is provided on the front side L1 of the front surface 139 of the tablet box 113 . The water removal part 81 is a plate-shaped member facing the flow from the input space 117 to the flow path 118 . Therefore, the water removal part 81 prevents water from directly contacting the front surface 139 of the tablet box 113 and can prevent water from flowing into the tablet box 113 .

The water removal part 81 is inclined with respect to the vertical. The water removal part 81 is inclined to push the lower end 81a of the water removal part 81 from the front surface 139 toward the front side L1. By moving the lower end 81a of the water removal part 81 away from the front surface 139, the water can be kept away from the bottom wall 136 of the tablet box 113. Therefore, it becomes difficult for water to pass through the mesh 132 b formed near the bottom wall portion 136 and flow into the inside of the tablet box 113 .

The lower end 81 a of the water removal part 81 is located at a lower height than the front surface 139 . In Embodiment 1, the lower end 81a of the water removal part 81 is located at a lower height than the bottom wall part 136. Moreover, the height dimension between the water removal part 81 and the inclined surface 118b is smaller than the height dimension between the bottom wall part 136 and the inclined surface 118b. Therefore, when the water hits the water removal part 81, the height of the liquid level S1 of the water is limited to a height lower than the lower end 81a downstream of the water removal part 81. With this structure, it is possible to further suppress water from hitting the tablet box 113 and flowing in.

As shown in FIG. 11B , the water removal part 81 covers the front surface 139 of the tablet box 113 ( FIG. 11A ). The width W1 of the water removal part 81 is larger than the width W2 of the inlet of the flow path 118 located in the connection part P. With this structure, it is possible to suppress the water in the injection space 117 from bypassing both sides of the water removal part 81 and flowing into the tablet box 113 .

The tablet box 113 has a restricting portion 121 protruding downward near the connection portion P ( FIG. 11A ) between the input space 117 and the flow path 118 . The restricting portion 121 extends across the direction from the input space 117 toward the flow path 118 to prevent the tablet J accidentally inserted into the input space 117 from entering the flow path 118 . In other words, the restriction part 121 has the function of reducing the opening area of the inlet of the flow path 118 . In Embodiment 1, the distance from the lower end of the restriction part 121 to the inclined surface 118b of the flow path 118 is smaller than the diameter D0 of the tablet J.

The width W3 of the restriction portion 121 is smaller than the width W2 of the flow path 118 . With this configuration, it is possible to suppress the inflow of water into the flow path 118 from being excessively restricted while restricting the entry of the tablet J into the flow path 118 .

In the water removal part 81, the input port 113a may be an opening for inserting the tablet J. For example, "tablet input" may be printed on the water removal unit 81 .

Each of the side walls 140 and 142 has a holding portion 113b protruding upward from both sides of the input port 113a. When detaching the tablet box 113 from the main body 114, the user can grasp the holding portion 113b to lift the tablet box 113. In Embodiment 1, the convex portion 113c extending linearly is formed on the side surface of the grip portion 113b so that the user can easily recognize that the grip portion 113b is a grippable member. The holding part 113b may have a different pattern from the convex part 113c.

As shown in FIGS. 12A and 12B , the tablet J has a disk shape and has a diameter D0 and a thickness T0. FIG. 12A shows a posture in which the tablet J is placed vertically with the thickness direction orthogonal to the insertion direction A2. FIG. 12B shows a posture in which the tablet J is placed laterally with the thickness direction parallel to the insertion direction A2.

The vertical position refers to a position in which the size in the vertical direction is larger than the size in the short side direction (for example, the thickness direction) of the tablet J in the horizontal cross section. In order to accommodate the longitudinally placed tablets J in the accommodation space R11, the up-down direction dimension D5 (Fig. 10A) of the tablet box 113 is larger than the width D2 (Fig. 9) in the width direction K, and the dimension D5 of the tablet box 113 in the accommodation space R11 is The dimension D4 in the front-rear direction L (Fig. 10A) is also larger than the width D2 in the width direction K. Since the dimension D4 in the front-rear direction L of the accommodation space R11 is substantially equal to the dimension D5 in the up-down direction of the tablet box 113, tablets J placed vertically can be accommodated in the accommodation space R11 while effectively utilizing the space. In addition, the vertically placed position refers to a position in which the movable outline is in contact with the mounting surface. In Embodiment 1, the tablet J moves along the outer periphery, and the posture in which the outer periphery of the tablet J contacts the placement surface is a posture in which the tablet J is placed vertically.

In Embodiment 1, the width D2 of the insertion port 113a is smaller than the diameter D0 of the tablet J, and is larger than the thickness T0 of the tablet J. The length D3 of the input port 113a is larger than the diameter D0 of the tablet J. Therefore, the tablet J passes through the insertion opening 113a in a vertical position. In other words, when the tablet J is placed sideways, it becomes difficult for the tablet J to pass through the insertion port 113a.

Returning to FIG. 10A , the mesh holes 132a, 132b, and 132c are composed of ribs 82 and 83 extending in two intersecting directions. In Embodiment 1, the meshes 132a, 132b, and 132c are composed of a plurality of ribs 82 extending in the lateral direction (front-rear direction L) and a plurality of ribs 83 extending in the longitudinal direction.

In the meshes 132a, 132b, 132c, ribs 82 (Fig. 8) extending in the transverse direction form the inner wall of the tablet box 113, and ribs 83 (Fig. 7) extending in the longitudinal direction form the outer wall of the tablet box 113. .

Here, the water supply to the tablet J will be described.

When the tablet J placed vertically is put into the inlet 113a, the tablet J will fall downward and reach the water supply position K2, and is held at the water supply position K2 by the holding part 138. The tablet J is dissolved by the water supplied from the water supply nozzles 12 and 13 (Fig. 8).

FIG. 13 is a top view showing the detergent supply unit 55 with the cover 100a removed. As shown in FIG. 13 , the water supply valves 10 a and 10 b ( FIG. 3 ) of the water supply member 10 are respectively connected to the paths F1 and F2 of the flow path member 101 . Paths F1 and F2 are formed independently of each other. The path F1 connected to the water supply valve 10a forms a flow path for supplying water to the bleach box 111 and the powder detergent box 112. The path F2 connected to the water supply valve 10b forms a flow path for supplying water to the softener box 110 and the tablet box 113. By supplying water to a plurality of cartridges through one path, the number of water supply valves in the water supply member 10 can be reduced and the structure can be simplified.

The path F2 can also supply water to the powder detergent box 112 in addition to the softener box 110 and tablet box 113 .

The path F2 forms an opening 14 facing the tablet box 113 , a plurality of openings 15 facing the softener box 110 , and an opening 16 facing the powder lotion box 112 . When the water supply valve 10a is opened and connected to the path F2 (see arrow B), water will flow into the tablet box 113 through the opening 14 and into the softener box 110 through the opening 15. On the other hand, the water that exceeds the openings 14 and 15 will flow into the powder lotion box 112 through the opening 16 .

FIG. 14 is a cross-sectional view of the detergent supply unit 55. As shown in FIG. 14 , water supply nozzles 12 and 13 extending downward from respective openings 14 are provided above the water supply position K2 and the input port 113 a. The water supply nozzles 12 and 13 form a flow path inside, and water is discharged into the tablet box 113 through the water supply nozzles 12 and 13 . Therefore, water is supplied to the tablet box 113 through the input port 113a.

In this structure, the input port 113a is used in addition to inputting the tablet J and also for supplying water. The opening area of the upper portion of the tablet box 113 can be reduced.

The water supply nozzles 12 and 13 are arranged in the front-rear direction L and are provided above the water supply position K2. More specifically, the water supply nozzles 12 and 13 are provided at positions facing the water supply position K2.

Fig. 15 is an enlarged perspective view of the water supply nozzles 12 and 13. As shown in FIG. 15 , the water supply nozzles 12 and 13 have the same shape, and discharge openings 24 and 25 for discharging water are formed at their respective lower ends. The discharge openings 24 and 25 are inclined in a direction shifted from directly below. The discharge opening 24 is inclined in the opposite direction relative to the discharge opening 25 . Therefore, water is discharged from the water supply nozzles 12 and 13 in opposite inclined directions.

FIG. 16A is a cross-sectional view of the manual input unit 56 along the width direction K through the accommodation space R11. Figure 16B is an enlarged view of the tablet box 113 of Figure 16A. FIG. 16C is a cross-sectional view of the manual input unit 56 along the width direction K through the drainage space R12.

As shown in FIG. 16A , the water discharged from the water supply nozzles 12 and 13 comes into contact with the side surface of the tablet J.

As shown in FIG. 16B , the water discharged from the water supply nozzles 12 and 13 collides with the side walls 140 and 142 along arrows B1 and B2 respectively, and then flows downward along the wall surface. By water hitting the side walls 140, 142, the flow rate of the water can be reduced. Since the water indirectly touches the side of the tablet J after once colliding with the side walls 140 and 142, compared with the case where the water directly touches the tablet J from the water supply nozzles 12 and 13, the water that touches the tablet J can be The flow rate and force of the water in Agent J are reduced. This water supply method can suppress the fragments of the tablet J from scattering due to the water supply. The tablet J is dissolved by water supply, and the water containing the dissolved tablet J will be discharged from the mesh 132b or flow into the drainage space R12 (Fig. 16C).

As shown in FIG. 14 , the water discharged from the mesh 132 b flows into the flow path 118 and flows toward the rear side L2 along the inclined surface 118 b. A gap D11 is formed between the bottom wall 136 and the inclined surface 118b in the accommodating space R11.

Water is supplied to the tablet box 113 and water is supplied to the softener box 110 at the same time. As a result, the liquid level in the accommodation 77 will rise.

As shown in FIG. 16B , since the tablet box 113 is removable, a slight gap is formed between the softener box 110 and the hooking portion 122 of the tablet box 113 . Therefore, when the liquid level rises, there is a possibility that water flows from the softener box 110 through the lower part of the hooking part 122 into the flow path 118 and the tablet box 113 due to capillary action.

As shown in FIG. 16A , a notch 145 functioning as an overflow structure is provided in the upper portion of the back surface 110 d of the softener box 110 . The notch 145 is a structure for draining water out of the softener box 110 before the liquid level reaches the upper part of the softener box 110 . Specifically, the notch 145 is a recessed portion in which a part of the upper edge of the back surface 110d is recessed downward. With this structure, even when the liquid level in the accommodating chamber 77 has risen, water is discharged from the notch 145 to the outside of the softener box 110 before flowing into the flow path 118 . Therefore, the flow of water from the softener box 110 into the tablet box 113 can be suppressed. Instead of the back surface 110d, or in addition to the back surface 110d, a notch 145 may be provided on the side surface away from the tablet box 113.

When water is supplied to the tablet box 113, water is also supplied to the powder lotion box 112. Therefore, the liquid level in the flow path 118 rises.

Returning to FIG. 14 , when water is supplied to the powder detergent box 112 , the water flows into the input space 117 and flows from the input space 117 into the flow path 118 . Therefore, even when the liquid level S1 in the injection space 117 has risen, the water that wants to flow into the flow path 118 still hits the water removal part 81 and flows into the flow path 118 from below the water removal part 81 . Due to the arrangement of the water removal part 81 , the height of the liquid level S1 in the flow path 118 is restricted to be lower than the height of the lower end 81 a of the water removal part 81 .

In addition, water is also supplied to the bleach box 111 at a time point different from the time point at which water is supplied to the tablet J. As a result, the liquid level in the housing 78 will rise.

As shown in FIG. 16A , similar to the softener box 110 , a notch 146 is provided in the upper portion of the back surface 111 d of the bleach box 111 . The flow of water from the bleach box 111 into the tablet box 113 can be suppressed. In addition, the mesh 132b is formed only in the first side wall 140 on the opposite side to the second side wall 142 facing the bleaching agent 111. It becomes difficult for water to enter the tablet box 113 through the second side wall 142 in the accommodation space R11. Therefore, it is possible to suppress water from flowing into the accommodating space R11 from the bleach box 111 and contacting the tablet J, and it is further possible to suppress the tablet J from starting to dissolve at a time when water supply to the tablet J is not scheduled.

As shown in FIG. 16C , water flowing into the drainage space R12 from the accommodating space R11 is discharged from the mesh holes 132 a and 132 c and flows into the flow path 118 . A gap D12 is formed between the bottom wall portion 136 and the inclined surface 118b in the drainage space R12, and the gap D12 is larger than the gap D11 (Fig. 16A). In other words, the bottom wall portion 136 in the drainage space R12 is farther away from the liquid surface S1 flowing in the flow path 118 than the bottom wall portion 136 in the accommodation space R11 ( FIG. 14 ). Therefore, even when the mesh holes 132 a and 132 c are formed in a wide range covering the side walls 140 and 142 , the backflow of water from the flow path 118 toward the tablet box 113 can be suppressed. [Summary]

The above description is integrated to describe the characteristics of this disclosure.

The washing machine 51 of Embodiment 1 has the tablet box 113 for manually inserting the tablet J for sterilization.

Since the tablet J is a solid treatment agent, it is required to dissolve the tablet J in order to supply it to the washing tank 4 . On the other hand, when water flows into the tablet box 113 at an undesirable time point, the tablet J is dissolved at that time point and is supplied to the washing tub 4 . As a result, Tablet J may adhere to the clothes and cause damage to the clothes. Therefore, in order to dissolve the tablet J at an appropriate time, it may be necessary to suppress the flow of water into the tablet box 113 outside of the appropriate time.

In the present disclosure, a gap D1 is provided between the tablet box 113 and the flow path 118 . In addition, the distance D12 between the drainage space R12 in which the mesh holes 132 a and 132 c are formed and the inclined surface 118 b is larger than the distance D11 between the accommodation space R11 of the tablet J and the inclined surface 118 b. By placing the mesh holes 132a and 132c through which water can flow in from the outside away from the liquid surface of the water flowing in the flow path 118, the inflow of water through the mesh holes 132a and 132c can be suppressed.

A water removal part 81 is provided on the front surface 139 of the tablet box 113 where the distance from the inclined surface 118b is the smallest and the risk of water inflow is high. In this structure, water is suppressed from directly contacting the front surface 139, and it is possible to suppress water from flowing into the inside of the tablet box 113 through the mesh 132b formed near the front surface 139. In addition, the water removal part 81 can suppress the height of the liquid level S1 downstream of the water removal part 81 to below the lower end 81 a of the water removal part 81 . Since the lower end 81 a is located lower than the bottom wall 136 , the liquid level S1 moves away from the bottom wall 136 , making it difficult for water to flow into the tablet box 113 .

Furthermore, when water is supplied to the tablet box 113 in order to dissolve the tablet J, when the water supply flow rate is large, the liquid level in the tablet box 113 rises. When the liquid level rises significantly, water may flow out from the input port 113a, and fragments of the tablet J may overflow from the input port 113a together with the flow of water. Therefore, in the present disclosure, there is a demand to promote drainage through the mesh holes 132a and 132c to suppress the liquid level in the tablet box 113 from rising to the input port 113a.

The tablet box 113 is partitioned by the narrow portion 137 into an accommodation space R11 for accommodating the tablet J and a drainage space R12 for restricting the entry of the tablet J. Since the entry of the tablet J into the drainage space R12 is suppressed, it is possible to suppress the tablet J or fragments of the tablet J from adhering to the mesh holes 132a, 132c and clogging the openings. Therefore, the drainage properties of the mesh holes 132a and 132c of the drainage space R12 can be maintained to ensure a drainage path. In addition, gaps R4 and R6 are provided between the mesh holes 132a and 132c and the outer side walls 110c and 111c of the boxes 110 and 111, thereby allowing water to pass through the mesh holes 132a and 132c and fall downward to the flow path. 118. [Effect 1]

According to the washing machine 51 of Embodiment 1, the following effects can be exerted.

As mentioned above, the washing machine 51 of this embodiment is a washing machine which can put in the water-soluble tablet J (solid agent). The washing machine 51 includes a washing tub 4 rotatably installed in the casing 2, a tablet box 113 (solid dosage box) for accommodating tablets J, and a path F2 (water supply path) for supplying water to the tablet box 113. The tablet box 113 has an accommodation space R11 and a drainage space R12. The accommodation space R11 accommodates the tablet J. The drainage space R12 is separated from the accommodating space R11 and has a space communicating with the accommodating space R11, and has mesh holes 132a and 132c (first drainage part) for draining the water supplied to the tablet box 113. ).

With this configuration, the accommodation space R11 for accommodating the tablet J and the drainage space R12 for draining water can be separated. Therefore, the fragments of the tablet J can be suppressed from clogging the mesh holes 132a and 132c, and the drainage performance of the tablet box 113 can be improved. By improving the drainage property, the tablet J can be efficiently dissolved and supplied to the washing tank 4 efficiently. In addition, compared with a structure in which the volume of the tablet box 113 is increased to increase the area of the mesh, drainage performance can be ensured by a small structure.

In the washing machine 51 of this embodiment, the tablet box 113 is provided with a narrow portion 137 and a holding portion 138 (restriction portion) for restricting the entry of the tablet J into the drainage space R12 between the accommodating space R11 and the drainage space R12.

With this configuration, the tablet J can be held in the accommodation space R11.

In the washing machine 51 of this embodiment, the tablet box 113 has the narrow part 137 whose width is narrower than the accommodation space R11 as a restriction part.

With this configuration, the tablet J can be held in the accommodation space R11 by the narrow portion 137 .

In the washing machine 51 of this embodiment, the narrow portion 137 has a shape in which the interval R4 (width of the opening) narrows downward.

With this configuration, the tablet J can be more reliably held in the accommodation space R11 through the narrow portion 137 . Even in a state where the tablet J having a vertically long shape is placed vertically, it can be held in the accommodation space R11.

In the washing machine 51 of this embodiment, the tablet box 113 has the holding portion 138 (extended portion) extending from the second side wall 142 (one side surface) of the tablet box 113 toward the first side wall 140 (the other side surface). Department of Restrictions.

With this structure, even when the tablet J dissolves and becomes thin, the tablet J can be more reliably held in the accommodation space R11.

In the washing machine 51 of this embodiment, boxes 110 and 111 (first members) are arranged outside the tablet box. The boxes 110 and 111 have outer side walls 110c and 111c (first wall portions) facing the mesh holes 132a and 132c. ). The intervals R4 and R6 between the mesh holes 132a and 132c and the outer side walls 110c and 111c become larger downward.

With this structure, drainage performance can be improved even in the lower portions of the mesh holes 132a and 132c where many fragments of the tablet J are located and are easily clogged. When the inclination angle of the mesh 132a, 132c is large, the opening area of the mesh 132a, 132c viewed from below can be increased. When the inclination angle of the mesh holes 132a and 132c is equal to or larger than the angle of the narrow portion 137, the mesh holes 132a and 132c themselves function as the narrow portion.

In the washing machine 51 of this embodiment, the accommodating space R11 and the drainage space R12 are connected in the front-rear direction L (lateral direction).

With this configuration, the size of the tablet box 113 in the vertical direction can be reduced. Therefore, space saving of the tablet box 113 can be achieved.

In the washing machine 51 of this embodiment, the areas of the mesh holes 132a and 132c are each 70% or more of the total area of the side walls 140 and 142 of the drainage space R12.

With this structure, the drainage performance of the tablet box 113 can be further improved. In addition, when the mesh holes 132a and 132c are also formed in the upper portions of the side walls 140 and 142 of the drainage space R12, even when the liquid level has risen, drainage can be efficiently performed through the mesh holes 132a and 132c.

In the washing machine 51 of this embodiment, the tablet box 113 is provided with the insertion port 113a (tablet insertion port) in the upper part.

With this configuration, compared to a configuration in which the insertion port 113a is provided in the middle of the tablet box 113, it is possible to prevent fragments of the tablet J that are partially dissolved with water from passing through the meshes 132a and 132c and exiting from the insertion port. 113a overflow situation.

In the washing machine 51 of this embodiment, the path F2 supplies water to the storage space R11 through the input port 113a.

With this structure, the input port 113a can be shared as a water supply port. Therefore, the opening area provided in the tablet box 113 is kept to a minimum, and the flow of fragments of the tablet J to the outside from the tablet box 113 can be suppressed.

In the washing machine 51 of this embodiment, the insertion port 113a is provided in the upper part of the accommodation space R11, and has a vertically long shape. The vertical dimension D5 of the accommodating space R11 is substantially the same as the longitudinal dimension D3 of the input port 113a.

With this configuration, the size of the accommodation space R11 in the up-down direction can be reduced while ensuring a space for accommodating the disk-shaped tablet J. Therefore, space saving of the tablet box 113 can be achieved.

In the washing machine 51 of this embodiment, the mesh 132b (second drain part) is formed in the accommodation space R11.

With this structure, water can be drained from the accommodation space R11, and the drainage performance of the tablet box 113 can be further improved.

In the washing machine 51 of this embodiment, the area of the mesh 132b is smaller than the areas of the meshes 132a and 132c.

With this structure, a certain level of water is maintained in the storage space R11 while draining water appropriately, thereby allowing the tablet J to be efficiently dissolved. [Effect 2]

The washing machine 51 of this embodiment is a washing machine which can put in the water-soluble tablet J (solid agent). The washing machine 51 is equipped with the washing tub 4, the tablet box 113 (solid agent box), the powder detergent box 112 (1st detergent box), the path F2 (1st water supply path), and the path F1 (2nd water supply path).
