Form for carrying out the invention (Knowledge and insights that form the basis of this disclosure, etc.) At the time when the inventors came up with the present disclosure, a water-soluble solid agent containing sodium dichloroisocyanurate was known as a technology of disinfectant for bathroom cleaning. The inventors used the technology of disinfectants for bathroom cleaning as a reminder and came up with the idea of a washing machine in which a disposable water-soluble solid agent is added to impart the solid agent component to the laundry.

The inventors discovered the following problem: when the solid dosage box containing the solid dosage is configured to be compact, it is difficult to dissolve the solid dosage without leaving any dissolved residue while suppressing water from overflowing from the solid dosage case. In addition, the following problem has been discovered: When the portion containing the solid agent in the solid agent box is configured to be large relative to the size of the solid agent, it is difficult to completely dissolve the fragments of the solid agent that become smaller when dissolved in water. . In order to solve these problems, this is the theme of this disclosure.

Furthermore, the inventors discovered the following problem: when water is poured directly into the solid agent from above, the portion of the solid agent that comes into contact with the water may be scraped to form a groove, and fragments of the solid agent may be formed. There is a risk that the jet flow generated by the formed groove will be scattered towards the surrounding area due to the rebound, and may remain behind. For example, if fragments of the solid agent remain in the box containing the solid agent, a user may mistakenly believe that the sterilization operation cannot be performed normally. Furthermore, when the case is formed of resin or the like, if fragments of the solid agent remain in the case, there is a risk that the resin of the case may be damaged. In order to solve these problems, this is the theme of this disclosure. (Embodiment 1)

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 insertion 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 a connection position with the input space 117 toward the rear side L2 to the discharge port 125 ( 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 .

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 181.

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 the 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 interval R5 (see FIG. 9 ) between the mesh holes 132a of the first side wall 140 and the mesh hole 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. 17A). 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 accommodation 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, or 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 restricting portion 123 is formed with edge portions 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 125 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 formed 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 125 .

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 181 is provided on the front side L1 of the front surface 139 of the tablet box 113 . The water removal part 181 is a plate-shaped member facing the flow from the input space 117 to the flow path 118 . Therefore, the water removal part 181 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 181 is inclined with respect to the vertical. The water removal part 181 is inclined to push the lower end 181a of the water removal part 181 from the front surface 139 toward the front side L1. By moving the lower end 181a of the water removal part 181 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 181 a of the water removal part 181 is located at a lower height than the front surface 139 . In Embodiment 1, the lower end 181a of the water removal part 181 is located at a lower height than the bottom wall part 136. Moreover, the height dimension between the water removal part 181 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 181, the height of the liquid level S1 of the water is limited to a height lower than the lower end 181a downstream of the water removal part 181. 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 181 covers the front surface 139 of the tablet box 113 ( FIG. 11A ). The width W1 of the water removal part 181 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 181 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 restriction portion 121 extends across the direction from the input space 117 toward the flow path 118 to prevent tablets J mistakenly input 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 181, 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 181.

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

In the mesh 132a, 132b, 132c, the rib 82a (FIG. 8) extending in the transverse direction forms the inner wall of the tablet box 113, and the rib 82b (FIG. 7) extending in the longitudinal direction forms 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 inserted into the insertion port 113a, the tablet J will fall downward and reach the water supply position K2, and will be held at the water supply position K2 by the holding portion 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 of 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 water supply nozzle 12. FIG. 16B is a cross-sectional view of the water supply nozzle 13.

As shown in FIG. 16A , the internal flow path 26 of the water supply nozzle 12 has a straight flow path 26 a and an end flow path 26 b. The straight flow path 26a extends downward from the opening 14. The end flow path 26b extends from the lower end of the straight flow path 26a to the discharge opening 24 at an angle with respect to the up-down direction. That is, the central axis C1 of the end flow path 26b is inclined with respect to the vertical direction.

In Embodiment 1, the cross section of the end flow path 26b is narrowed from the upstream toward the discharge opening 24, and the cross section of the end flow path 26b is formed in a tapered shape. Therefore, the water passing through the end flow path 26 b flows so as to be concentrated on the central axis C1 and is easily discharged from the discharge opening 24 in the direction along the central axis C1 (obliquely downward).

As shown in FIG. 16B , the internal flow path 27 of the water supply nozzle 13 has a straight flow path 27 a and an end flow path 27 b like the internal flow path 26 of the water supply nozzle 12 . The end flow path 27b of the water supply nozzle 13 is inclined in the opposite direction to the end flow path 26b of the water supply nozzle 12. Therefore, the central axis C2 of the end flow path 27b is inclined in the opposite direction to the central axis C1. With this structure, the water discharged from the discharge opening 25 is discharged to the opposite side to the water discharged from the discharge opening 24 . Thereby, the tablet J can be moistened more evenly from both sides. The inclination angles of the end flow path 26b and the end flow path 27b may be the same.

FIG. 17A is a cross-sectional view of the manual input unit 56 along the width direction K through the accommodation space R11. Figure 17B is an enlarged view of the tablet box 113 of Figure 17A. FIG. 17C 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. 17A , 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. 17B , 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. 17C).

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. As shown in FIG. 17A , a gap D11 is formed between the bottom wall portion 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. 17B , 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. 17A , 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 181 and flows into the flow path 118 from below the water removal part 181 . Due to the arrangement of the water removal part 181, the height of the liquid level S1 in the flow path 118 is restricted to be lower than the height of the lower end 181a of the water removal part 181.

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. 17A , 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. 17C , the water flowing into the drainage space R12 from the accommodation 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. 17A). 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.

Returning to FIG. 6 , the flow path members 115 and 116 each form restriction portions 119 and 120 that restrict the entry of the tablet J. The flow path member 116 has a restricting portion 120 protruding in the front-rear direction L between the insertion port 111 a and the inner bottom surface 111 b of the box 111 . The restricting portion 120 extends across the falling direction of the tablet J to prevent the tablet J inserted into the box 111 from reaching the inner bottom surface 111 b of the box 111 . The restriction unit 120 is provided upstream of the inlet of the liquid discharge flow path 74 . The flow path member 115 similarly has a restriction portion 119 protruding in the front-rear direction L. [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 181 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 181 can suppress the height of the liquid level S1 downstream of the water removal part 181 to below the lower end 181 a of the water removal part 181 . Since the lower end 181 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 (restricting portion) between the accommodation space R11 and the drainage space R12. The narrow portion 137 and the holding portion 138 limit the tablets. Agent J is responsible for entering 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 R5 (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.

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 configuration, 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.

The powder detergent box 112 has an inclined surface 118 b that is inclined downward away from the tablet box 113 with a distance D1 between the input space 117 and the discharge port 125 in a direction away from the input space 117 .

With this configuration, when water flows on the inclined surface 118b, the liquid level S1 moves away from the tablet box 113 as it enters the downstream of the flow path 118. Therefore, it is difficult for water to touch the tablet box 113 and flow into the inside of the tablet box 113 .

In the washing machine 51 of this embodiment, the distance D1 is the smallest in the front surface 139 of the tablet box 113 (the surface of the solid tablet box adjacent to the input space 117).

With this structure, it is difficult for water to touch the part of the tablet box 113 far away from the front surface 139 and to flow into the inside of the tablet box 113 .

In the washing machine 51 of this embodiment, the inclined surface 118b is inclined downward with respect to the bottom wall 136 of the tablet box 113 .

With this configuration, the water surface moves away from the bottom wall 136 of the tablet box 113 as it enters the downstream of the flow path 118 . Therefore, it is difficult for water to hit the bottom wall portion 136 and flow into the inside of the tablet box 113 .

In the washing machine 51 of this embodiment, the bottom wall 136 of the tablet box 113 extends horizontally.

With this configuration, when the tablet box 113 has an openable and closable structure, the tablet box 113 can be easily manufactured.

In the washing machine 51 of this embodiment, the water removal part 181 is provided upstream of the tablet box 113 . The height dimension between the water removal part 181 and the inclined surface 118b is smaller than the height dimension between the bottom wall part 136 of the tablet box 113 and the inclined surface 118b.

With this structure, it is possible to further suppress water from flowing into the inside of the tablet box 113 through the mesh 132b near the front surface 139.

In the washing machine 51 of this embodiment, the front surface 139 of the tablet box 113 is located at the connection portion P between the input space 117 and the flow path 118 . The width W1 of the water removal part 181 is larger than the width W2 of the inlet of the flow path 118 .

With this configuration, it is possible to suppress water from flowing into the tablet box 113 from the side of the water removal part 181 .

In the washing machine 51 of this embodiment, the mesh holes 132a and 132c (drainage parts) are formed on the side walls 140 and 142 of the tablet box 113.

With this configuration, it is possible to suppress the inflow of water into the tablet box 113 compared to a case where the mesh holes 132 a and 132 c are formed in the bottom wall 136 or the front surface 139 of the tablet box 113 .

In the washing machine 51 of this embodiment, the tablet box 113 has an accommodating space R11 having a water supply position K2 for accommodating tablets J, and a drainage space R12 for draining water supplied to the tablet box 113 . The accommodating space R11 is arranged closer to the input space 117 than the drainage space R12. Mesh holes 132a and 132c (drainage parts) are formed on the side walls 140 and 142 of the drainage space R12.

With this structure, compared with the case where the drainage space R12 is arranged on the front side L1 of the accommodating space R11, the water that has passed through the mesh holes 132a and 132c can be suppressed from flowing backward toward the drainage space R12.

The washing machine 51 of this embodiment further has: a softener box 110 (second detergent box), which contains softener (second detergent); and a bleach box 111 (third detergent box), which contains liquid bleach. (3rd detergent). The tablet box 113 is arranged between the softener box 110 and the bleach box 111 . Path F2 supplies water to the tablet box 113 and the softener box 110 . Path F1 supplies water to the powder detergent box 112 and the bleach box 111 . A mesh 132b (drainage part) is formed in the first side wall 140 of the accommodation space R11 adjacent to the softener box 110.

With this configuration, the softener box 110 and the tablet box 113 share the path F2. The bleach box 111 supplies water through a different path F1. Therefore, water supply can be provided to the tablet box 113 and the bleach box 111 at different time points. Since the first side wall 140 forming the mesh 132b is away from the bleach box 111, it is possible to suppress water from passing through the mesh 132b from the bleach box 111 when the water supply to the tablet box 113 is stopped.

In the washing machine 51 of this embodiment, the softener box 110 and the bleach box 111 have insertion openings 110a and 111a (openings) into which detergent can be inserted into the upper portions. The tablet box 113 has a hooking portion 122, which protrudes from the upper portion in the lateral direction and is hooked on the edge of the insertion port 110a of the softener box 110 and the edge of the insertion port 111a of the bleach box 111.

With this configuration, the tablet box 113 can be stably arranged by providing the hooking portion 122 that hooks the insertion openings 110a and 111a. Moreover, since the hooking part 122 covers part of the insertion openings 110a and 111a, it is possible to suppress water from flowing into the tablet box 113 from the softener box 110 or the bleach box 111.

In the washing machine 51 of this embodiment, the softener box 110 has the back surface 110d (wall part) which forms the accommodation part 77 (detergent accommodation part) which accommodates softening agent. A notch 145 is provided at an upper portion away from the back surface 110d of the flow path 118. The notch 145 has a recessed shape that is depressed downward.

With this structure, when the liquid level of the softener box 110 rises, the water can overflow through the notch 145 and be discharged out of the softener box 110 . By suppressing the rise of the liquid level in the softener box 110 , water can be suppressed from flowing into the tablet box 113 from the softener box 110 . [Effect 3]

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

As described above, the washing machine 51 of this embodiment includes the washing tub 4 which is rotatably installed in the casing 2 and the detergent supply unit 55 which supplies detergent to the washing tub 4 . The detergent supply unit 55 has a detergent box 111 (first detergent box) and a tablet box 113 (solid agent box). The detergent box 111 is provided with an inlet 111 a (first detergent inlet) into which detergent (first detergent) can be put in, and the detergent is accommodated and supplied to the washing tub 4 . The tablet box 113 is provided with an inlet 113 a (solid agent inlet) into which water-soluble tablets J (solid agent) can be put in, and the tablets J are accommodated and supplied to the washing tub 4 . The detergent box 111 is provided with an accommodating portion (detergent accommodating portion) for accommodating the detergent, and a restricting portion 120 for restricting the passage of the tablet J.

With this configuration, the tablet J can be prevented from being accidentally inserted into the insertion port 111a. Even if the tablet J is put into the detergent box 111 by mistake, the passage of the tablet J is still restricted, so it becomes easy to take the tablet J out of the detergent box 111 and put it into the correct place. By reinjection, tablet J can reach the water supply position K2 and receive water supply at an appropriate time point.

In the washing machine 51 of this embodiment, the restriction part 120 protrudes in the front-rear direction L (lateral direction) between the insertion port 111a and the inner bottom surface 111b of the box 111.

With this structure, the tablet J accidentally thrown into the box 111 will hit the restricting portion 120 and become difficult to reach the inner bottom surface 111 b of the detergent box 111 . In addition, the input port 113a is not located near the end of the manual input unit 56, but is located between the input port 111a and the input port 110a. Therefore, even if the tablet J is accidentally dropped from the hand, the tablet J can be prevented from falling directly into the washing tub 4 . Since the restricting portions 119 and 120 are provided on the left and right sides of the input port 113a, even if the tablet J is accidentally dropped from the hand to the left and right sides of the input port 113a, it will still be caught in either the left and right restricting portions 119, 120. Therefore, accidental feeding of the tablet J can be suppressed. Even if the tablet J is inserted by mistake, the tablet J stops at a position closer to the insertion openings 110 a and 111 a than the bottom surfaces of the boxes 110 and 111 , so the tablet J becomes easy to take out.

In the washing machine 51 of this embodiment, the detergent supply unit 55 has the liquid discharge flow path 74 (discharge part) and discharges the detergent and water from the storage space. The restriction part 120 is provided at the entrance of the liquid discharge flow path 74 .

With this configuration, even if the tablet J is mistakenly dropped into the insertion port 111a, the tablet J can be prevented from reaching the liquid discharge channel 74.

In the washing machine 51 of this embodiment, the tablet box 113 has a first side wall 140; a second side wall 142 facing the first side wall 140; and a rotation axis X (connection part) connecting the first side wall 140 and the second side wall. 142 can be connected open and closed.

With this configuration, by rotating the tablet box 113 about the rotation axis X, the facing state of the side walls 140 and 142 can be released. Therefore, the inner wall of the tablet box 113 becomes easy to access, making it easy to clean or maintain the tablet box 113, and the fragments of the tablet J attached to the inner wall can be washed away.

In the washing machine 51 of this embodiment, the first side wall 140 and the second side wall 142 have mesh holes 132a and 132c (drainage parts) formed to allow water to pass therethrough.

With this structure, by providing the mesh holes 132a and 132c in the side walls 140 and 142, the drainage performance of the tablet box 113 can be further improved. Therefore, even when the volume of the tablet box 113 is small, the water level in the tablet box 113 is still suppressed from rising, and the fragments of the tablet J can be suppressed from adhering to the upper part of the tablet box 113 and dissolving and remaining. .

In the washing machine 51 of this embodiment, the first side wall 140 has a hooking portion 122 (first hooking portion) protruding outward from the water supply position K2 (tablet accommodating place), and the second side wall 142 has a hooking portion protruding from the water supply position K2 The hooking part 122 (the second hooking part) protrudes outward.

With this configuration, the tablet box 113 can be stably held in the manual insertion unit 56 by providing the hooking portions 122 on the side walls 140 and 142 on both sides.

In addition, although the example in which the accommodating space R11 and the drainage space R12 are arranged in the front-back direction L in the tablet box 113 was demonstrated, it is not limited to this. For example, as shown in Modifications 1 and 2 described below, the accommodating space R11 and the drainage space R12 may be arranged in the vertical direction. [Modification 1]

As shown in FIG. 18 , Modification 1 is different from the tablet box 113 of Embodiment 1 in that the storage space R11 and the drainage space R12 are arranged in order from above. In this structure, the storage space R11 for accommodating the tablet J may be separated from the drainage space R12 for main drainage, and the drainage performance of the mesh 232a formed in the drainage space R12 may be improved. In addition, since the water supplied from the input port 213a does not stay in the accommodation space R11 but falls into the drainage space R12, the drainage efficiency in the mesh 232a is improved. [Modification 2]

FIG. 19 is a schematic diagram of the tablet box 313 of Modification 2. As shown in FIG. 19 , Modification 2 is different from the tablet box 113 of Embodiment 1 in that the drainage space R12 and the accommodation space R11 are arranged in order from above. In this structure, the storage space R11 for accommodating the tablet J may be separated from the drainage space R12 for mainly draining water, and the drainage performance of the mesh 332a formed in the drainage space R12 may be improved. In addition, since the tablet J will stay in the drainage space R12 due to gravity, even if the narrow portion 137 or the holding portion 138 is not provided, the entry of the tablet J into the drainage space R12 can still be restricted. With this structure, the structure of the tablet box 313 can be further simplified. (Embodiment 2)

Moreover, after the water supply valve 10a or the water supply valve 10b is closed and the water supply is stopped, the liquid and water in the box 60 or the box 61 are also in the flow path between the inlet members 65 and 66 and the liquid discharge channels 73 and 74. It is discharged from the opening 60a or the opening 61a due to the siphon phenomenon. According to this, water can be prevented from remaining in the box 60 or the box 61.

On the other hand, in the powdered detergent box 62, no member forming an inlet is disposed, but the entire upper surface is opened upward.

The tablet box 63 is a member that accommodates a water-soluble solid agent used in one sterilization washing course. When the solid agent is sprayed with water, the solid agent is dissolved, and the dissolved solid agent is supplied to the washing tank 4 . 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 2, tablet J is demonstrated as an example of a solid agent.

The tablet box 63 is formed with an insertion port 63a for inserting the tablet J on the front side L1. When the tablet box 63 is arranged in the main body 64, the input port 63a is arranged between the input port 65a and the input port 66a arranged in the width direction K.

Specifically, the tablet box 63 has a hooking portion 80a, a hooking portion 81a, and a holding portion 81b that protrude toward the outside of the tablet box 63. The hooking portion 80a, the hooking portion 81a, and the holding portion 81b are hooked on the main body. 64.

As shown in FIG. 25 , openings 60 a , 61 a , 62 a and 67 a are provided on the bottom surface 64 a of the main body 64 at positions corresponding to the respective boxes 60 , 61 , 62 and the space 67 . When water is supplied from the water supply member 10 to the respective boxes 60 , 61 , 62 , and 63 , the contained liquid flows out toward the washing tub 4 from the respective openings 60 a, 61 a, 62 a, and 67 a together with the water.

26 and 27 are perspective views of the input port member 65. In the following description, only the inlet member 65 is shown in the figure, but the inlet member 66 also has a similar structure. The input port member 66 has a guide part 168 like the guide part 68 of the input port member 65 (FIG. 23).

As shown in FIGS. 26 and 27 , the input port member 65 has a guide portion 68 , a guide portion 69 , and an engaging portion 75 . The guide part 68 is a wall part that defines the range of the input port 65a, and guides the liquid from the periphery of the input port 65a to the input port 65a. The guide part 69 is a flow path member extending downward from the input port 65a, and guides the liquid from the input port 65a to the inside of the input port member 65 (box 60). The engaging portion 75 is a flow path member covering the liquid discharge flow path 73 .

In Embodiment 2, the guide part 68 extends in the lateral direction with respect to the tablet J inserted in the vertical direction.

The opening size of the input port 65a defined by the guide portion 68 is smaller than the outer size of the tablet J. The opening size is the largest size across the input port 65a. More specifically, the diagonal length D21 of the insertion port 65a is smaller than the diameter D0 of the tablet J. Therefore, regardless of the posture of the tablet J, it becomes difficult for the tablet J to pass through the insertion port 65a. In Embodiment 2, the input port 65a has a substantially square shape or a rounded square shape. Therefore, when the tablet J is a disk, even if the dimensional difference between the length D21 and the diameter D0 is small, it becomes difficult for the tablet J to fit into the input port 65 a and becomes easy to collect from the vicinity of the input port member 65 Tablet J.

The guide portion 68 defining the insertion opening 65a through which the tablet J is difficult to pass functions as a restricting portion. In this specification, the restricting part refers to a member that prevents the tablet J from accidentally reaching the washing tub 4 . The restricting portion is a structure that prevents the entry of the tablet J when the tablet J inserted into the wrong box (that is, a box other than the tablet box 63 ) is about to enter the depth of the box, such as the accommodating space 77 . The restricting portion may be a narrow portion of the passage, a protrusion protruding in a direction intersecting the direction in which the tablet J is to enter, a mesh, or the like. On the other hand, the restricting portion is configured so as to hardly hinder the passage of the liquid normally put into the cassette.

As shown in FIG. 27 , the guide portion 69 guides the liquid injected from the input port 65 a toward the lotion box 60 . The guide portion 69 has an opening on one side thereof, and the injected liquid is guided along the arrow A1. The guide part 69 has a flat surface 69a at a position facing the input port 65a. Even if a part of the tablet J dissolves and becomes small and passes through the insertion port 65a, by allowing the flat surface 69a to receive the tablet J, it is possible to prevent the tablet J from reaching the bottom of the accommodating place 77 and becoming difficult to take out.

28A and 28B are perspective views of the tablet box 63. FIG. 28C is a plan view of the tablet box 63. Fig. 28D is a cross-sectional view of the tablet box 63 taken along line A-A in Fig. 28C.

In Embodiment 2, the tablet box 63 has a one-sided open structure, and has one side wall 80, and the opposite side is open.

As shown in FIG. 28A , on one side of the side wall 80 , the peripheral wall 81 , the protruding portion 87 , the protruding portion 88 , the protruding portion 83 a and the protruding portion 83 b are provided to protrude in the width direction K (short side direction). The peripheral wall 81 protrudes from the outer peripheral portion of the side wall 80 and forms the front, bottom and back surfaces of the tablet box 63 . The protrusions 87 and 88 are provided inside the peripheral wall 81 . The protrusions 83a and 83b are provided on the upper portion of the side wall 80 .

As shown in FIG. 28B , a hooking portion 80a is provided on the other side of the side wall 80 . The hooking portion 80a protrudes in the opposite direction to the peripheral wall 81 (outside of the tablet box 63). By hanging the hooking portion 80a on the lotion box 60, the tablet box 63 will be supported by the main body portion 64 (Fig. 5).

As shown in FIG. 28A , the tablet box 63 has openings on its upper portion and on the surface facing the side wall 80 . In Embodiment 2, the outer side wall 89 ( FIG. 28D ) of the softener box 61 functions as the other side wall of the tablet box 63 .

The side wall 80 has a mesh 82 penetrating in the thickness direction (width direction K) of the side wall 80 . The dissolved tablet J flows out from the mesh 82 together with water and is supplied to the washing tank 4 .

The peripheral wall 81 has an inclined surface 84 arranged in the front-rear direction L, a vertical wall portion 85, and a bottom wall portion 86. The inclined surface 84 is a wall portion that is inclined downward with respect to the horizontal direction toward the rear side L2 below the input port 63a. The inclined surface 84 guides the tablet J inserted into the input port 63a to the water supply position K1 on the rear side L2 along the direction of gravity. The vertical wall portion 85 is a wall portion extending downward from the lower end of the inclined surface 84 and forms a step between the inclined surface 84 and the bottom wall portion 86 . The bottom wall portion 86 is a wall portion extending in the front-rear direction L from the lower end of the vertical wall portion 85 . The bottom wall portion 86 defines the water supply position K1 at a position away from the lower end of the vertical wall portion 85 on the rear side L2.

Here, the water supply position K1 refers to the position of the bottom wall portion 86 where the tablet J is placed when water is supplied. The water supply position K1 is a position assumed to be reached after the tablet J has been inserted.

The water supply position K1 cooperates with the peripheral wall 81 and the protruding portion 88 to form an accommodation space K10 for accommodating tablets. The accommodating space K10 is an area where the tablet J is present when the tablet J is already accommodated in the tablet box 63 . The accommodation space K10 may also be larger than the shape of the tablet J. In other words, the size of the accommodation space K10 is determined so that the tablet J can be included in the accommodation space K10. In Embodiment 2, the dimension D24 in the front-rear direction L of the accommodation space K10 is larger than the diameter D0 of the tablet J (Fig. 12A, Fig. 12B). The accommodating space K10 has a longitudinal shape that is long in the front-rear direction L in a plan view viewed from the vertical direction. In Embodiment 2, the short side direction of the accommodation space K10 is horizontal (width direction K). Specifically, the dimension D24 of the accommodation space K10 in the front-rear direction L is larger than the dimension D26 of the accommodation space K10 in the width direction K.

The water supply nozzles 12 and 13 of the flow path member 11 are formed in the upper part of the accommodation space K10. The accommodation space K10 can also be provided directly below the water supply nozzles 12 and 13 . The dimension D27 of the accommodation space K10 in the vertical direction is larger than the dimension D26 of the accommodation space K10 in the width direction K. In Embodiment 2, the dimension D27 of the accommodation space K10 in the vertical direction is equal to the dimension D24 of the accommodation space K10 in the front-rear direction L. The dimension D27 in the vertical direction may be larger than the dimension D24 in the front-rear direction L.

In addition, a plurality of point-shaped protrusions 92 that protrude in the width direction K and come into contact with the softener box 61 are formed on the peripheral wall 81 around the accommodating space K10. In Embodiment 1, four protrusions 92 are formed and have a spherical shape. The four protrusions 92 are configured to surround the accommodation space K10.

The end portion of the front side L1 of the peripheral wall 81 forms a hooking portion 81a that is bent relative to the front surface and protrudes toward the front side L1. The end of the peripheral wall 81 on the rear side L2 forms a gripping portion 81b that is bent relative to the back surface and protrudes toward the rear side L2.

The hooking part 81a and the holding part 81b are hooked on the wall defining the space 67 (Fig. 24). In addition, when detaching the tablet box 63 from the main body 64 , the user can grasp the holding portion 81 b to lift the tablet box 63 . A pattern may also be added to the gripping part 81b so that the user can easily identify that the gripping part 81b is a grippable component. In Embodiment 1, the convex portion 81c extending linearly is formed on the upper surface of the grip portion 81b.

As shown in FIG. 28C , the protruding portion 87 is provided between the lower end of the inclined surface 84 and the water supply position K1 at a position with a gap R21 in the front-rear direction L from the lower end of the inclined surface 84 . The protrusion 87 is a member for guiding the tablet J from the inclined surface 84 to the water supply position K1. Therefore, the width D25 of the gap R21 between the protrusion 87 and the inclined surface 84 is smaller than the diameter D0 of the tablet J. The protrusion 87 may be inclined downward toward the rear side L2. The protrusion 87 may also be formed along the inclined surface 84 , for example, along an extension line of the inclined surface 84 .

The protrusion 87 is away from the peripheral wall 81 . A space R22 is formed below the protruding portion 87 and between the protruding portion 87 and the peripheral wall 81 .

The protruding part 88 is provided at a position spaced apart from the lower end of the protruding part 87 between the protruding part 87 and the water supply position K1. The protruding portion 88 functions as a holding portion for holding the tablet J in the accommodation space K10. Therefore, the protrusion 88 is provided at a height from the bottom wall 86 to the diameter D0 of the tablet J or less. The protrusion 88 may extend in the up-and-down direction. With this structure, compared with the case where the protruding portion 88 extends in the front-rear direction L, it becomes easier to stably hold the tablet J in the accommodation space K10.

The protrusion 88 is away from the peripheral wall 81 and is provided at a position with a gap R23 upward from the bottom wall 86 . Therefore, the space R22 below the protruding part 87 and the accommodation space K10 are connected through the gap R23 below the protruding part 88 . By providing the gap R23, the water supplied to the accommodation space K10 will flow into the space R22 and be drained through the mesh 82 provided in the space R22. Therefore, the water level in the tablet box 63 can be suppressed from rising. Furthermore, a gap R21 is formed between the inclined surface 84 and the protruding portion 87 . Even if the water level rises and water rushes onto the protruding portion 87 , the water can still be caused to fall to the space R22 through the gap R21 . Therefore, it is possible to suppress the water from pushing up the fragments of the tablet J onto the inclined surface 84 . Compared with the case where the inclined surface 84 and the protruding portion 87 are continuous, the areas of the inclined surface 84 and the protruding portion 87 can be reduced, thereby suppressing fragments of the tablet J from remaining on the inclined surface 84 or the protruding portion 87 .

In the peripheral wall 81, the inclined surface 84, the vertical wall portion 85, and the bottom wall portion 86 are smoothly connected. The corner portion between the vertical wall portion 85 and the bottom wall portion 86 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 the dissolution of the tablet J can be suppressed.

As shown in FIG. 28D , the peripheral wall 81 protrudes from the side wall 80 toward the outer wall 89 of the softener box 61 . The outer side wall 89 thus forms the other side wall of the tablet box 63 . The side wall 80 and the outer wall 89 are facing each other. On the other hand, when the tablet box 63 is removed from the main body 64, since the outer wall 89 remains in the main body 64, the opposing state between the side wall 80 and the outer wall 89 is automatically released. By releasing the facing state, the inner wall of the tablet box 63 becomes easily accessible, making it easy to clean or maintain the inner wall of the tablet box 63 .

The size of the peripheral wall 81 in the width direction K is smaller than the size of the side wall 80 in the front-rear direction L. That is, the width direction K in which the peripheral wall 81 protrudes becomes the short-side direction in the tablet box 63 , and the depth from the side wall opening facing the side wall 80 to the inner wall surface of the side wall 80 is shallow. With this structure, it is easier to access the inner wall surface of the side wall 80, making maintenance easier. The mesh 82 is opposite to the side wall opening and is provided on the inner wall surface of the side wall 80 . Therefore, the mesh 82 is easily accessible through the side wall opening, making maintenance such as cleaning easy.

The protrusions 83a and 83b come into contact with the upper part of the outer side wall 89. The protrusions 83a and 83b push the outer wall 89 back even if the outer wall 89 bulges outward when the main body 64 is formed. In other words, the protruding parts 83a and 83b have the function of correcting the shape of the softener box 61. With this structure, the space inside the tablet box 63 can be ensured. By forming the protrusions 83 a and 83 b near the center of the tablet box 63 , the deflection of the softener box 61 can be corrected over a wider range than in the case where the protrusions 83 a and 83 b are provided at the ends of the tablet box 63 in the front-rear direction L. song. In addition, when the softener box 61 is molded from resin, since it is long in the front-rear direction L, it becomes easy to bulge in the width direction K. However, by providing the protrusions 83a and 83b, it can be used more appropriately. Parts molded from resin.

The protrusion 92 also touches the outer side wall 89 . Therefore, a gap R24 is formed between the peripheral wall 81 and the outer side wall 89 of the softener box 61 . With this structure, water is drained from between the peripheral wall 81 and the outer side wall 89 . By providing the gap R24 in the peripheral wall 81 to provide a drainage path other than the mesh hole 82, drainage becomes possible even when the mesh hole 82 is clogged. Furthermore, compared with the case of providing a gap in the bottom wall portion 86 , by providing the gap R24 in the peripheral wall 81 , the tablet box 63 can be easily manufactured. The dimension D28 in the width direction K of the gap R24 may be smaller than the opening size of the mesh 82 . With this structure, even if water passes through the gap R24, the function of the mesh 82 as a filter will not be impaired.

Since the protrusion 92 has a spherical shape, the contact area with the softener box 61 can be reduced, and the friction between the tablet box 63 and the softener box 61 can be reduced. Therefore, removal of the tablet box 63 becomes easy.

When the protrusion 83a contacts the outer wall 89, as shown in FIG. 28A, the protrusion 83a divides the upper opening of the tablet box 63 into the insertion port 63a on the front side L1 and the opening 63b on the rear side L2. The opening 63b is located above the accommodation space K10. The input port 63a is an opening for inserting the tablet J, and the opening 63b is an opening for pouring water into the tablet J from the water supply nozzles 12 and 13. In addition, the opening 63b is also an opening for confirming whether the tablet J has been inserted.

Returning to FIG. 22 , when the main body 64 is pulled out from the unit box 50 , the insertion opening 63 a covers the entire surface and is exposed. The input port 63a may have a longitudinal shape, that is, the width D2 of the input port 63a may be smaller than the length D3 in the front-rear direction L of the input port 63a. On the other hand, when the main body 64 is pulled out from the unit box 50, a part of the opening 63b is exposed. The user can view the inside of the tablet box 63 through the opening 63b and confirm whether the tablet J has been inserted. The opening size of the exposed opening 63b may also be smaller than the outer size of the tablet J.

In addition, as shown in FIGS. 28A and 28B , the mesh 82 may be composed of ribs 82 a and 82 b extending in two intersecting directions. In Embodiment 2, the mesh 82 is composed of a plurality of ribs 82a (Fig. 28A) extending in the transverse direction (front-rear direction L) and a plurality of ribs 82b (Fig. 28B) extending in the longitudinal direction. .

In the mesh 82 , ribs 82 a extending in the transverse direction form the inner wall of the tablet box 63 , and ribs 82 b extending in the longitudinal direction form the outer wall of the tablet box 63 . Since the supplied water first touches the ribs 82 a extending in the transverse direction, it becomes difficult for the water to flow downward, and more water is discharged to the outside of the tablet box 63 through the mesh 82 . Therefore, the water level in the tablet box 63 can be maintained low. It is possible to suppress the water from overflowing from the tablet box 63 and the water containing the fragments of the tablet J from overflowing from openings such as the insertion port 63 a in the upper part of the tablet box 63 . In addition, the low water level can suppress the fragments of the tablet J from floating on the upper part of the tablet box 63 without being dissolved and remaining in the tablet box 63 .

In order to accommodate the longitudinally placed tablet J in the accommodation space K10, the dimension D27 in the vertical direction of the accommodation space K10 is larger than the dimension D26 in the width direction K, and the dimension D24 in the front-rear direction L of the accommodation space K10 is also larger than the dimension D26 in the width direction K. The dimension D26 in the width direction K is larger (Fig. 28A). In order to effectively utilize the space, the longitudinally placed tablet J is accommodated in the accommodation space K10. The dimension D24 in the front-rear direction L of the accommodation space K10 is approximately the same as the diameter D0 of the tablet J, and the dimension D26 in the width direction K is the same as the diameter D0 of the tablet J. The thickness T0 of agent J is approximately the same. In addition, the vertically placed position refers to a position in which the movable outline is in contact with the mounting surface. In the embodiment, the tablet J moves along the outer periphery, and the posture in which the outer periphery of the tablet J is in contact with the placement surface is a posture in which the tablet J is placed vertically.

In Embodiment 2, the width D2 of the insertion port 63a 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 63a is larger than the diameter D0 of the tablet J. Therefore, the tablet J passes through the insertion opening 63a 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 63a.

In order to put the tablet J placed vertically into the tablet box 63 and accommodate it while effectively utilizing the space in the width direction K, the width D2 of the insertion opening 63a is substantially the same as the thickness T0 of the tablet J. That is, the width D2 of the input port 63a is substantially the same as the dimension D26 (FIG. 28A) of the accommodation space K10 in the width direction K.

As shown in FIG. 28C , when the tablet J placed vertically is inserted into the input port 63 a, the tablet J rolls on the inclined surface 84 and the protruding portion 87 to reach the water supply position K1 . Therefore, through the arrangement of the protruding portion 88, the tablet J will be retained in the accommodation space K10.

When the tablet J is placed in the storage space K10, the tablet J is dissolved by the water supplied from the water supply nozzles 12 and 13 (Fig. 30).

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

FIG. 29 is a top view of the detergent supply unit 5 with the cover 50a removed. As shown in FIG. 29 , the three water supply valves 10 a , 10 b , and 10 c ( FIG. 22 ) of the water supply member 10 are respectively connected to the paths F1 , F2 , and F3 of the flow path member 11 . Paths F1, F2, and F3 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 lotion box 60 and the powder lotion box 62. The path F2 connected to the water supply valve 10b forms a flow path for supplying water to the softener box 61 and the tablet box 63. Path F3 connected to the water supply valve 10 c forms a flow path for supplying water to the automatic injection unit 7 . 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 forms openings 14 and 15 facing the tablet box 63 and a plurality of openings 16 facing the softener box 61 . When the water supply valve 10b is opened and connected to the path F2, water flows into the tablet box 63 through the openings 14 and 15 (see arrow B). On the other hand, the water that exceeds the openings 14 and 15 will flow into the softener box 61 through the opening 16 .

FIG. 30 is a cross-sectional view of the detergent supply unit 5. As shown in FIG. 30 , a water supply nozzle 12 extending downward from the opening 14 and a water supply nozzle 13 extending downward from the opening 15 are provided on the upper part of the tablet box 63 . The water supply nozzles 12 and 13 are cylindrical members and form internal flow paths 26 and 27 . Therefore, the water flowing into the openings 14 and 15 is discharged into the tablet box 63 through the internal flow paths 26 and 27 .

The water supply nozzles 12 and 13 are arranged in the front-rear direction L and are provided above the water supply position K1. More specifically, the water supply nozzles 12 and 13 are provided at positions facing the water supply position K1.

FIG. 31A is a schematic cross-sectional view of the tablet box 63 viewed from the front-rear direction L. FIG. FIG. 31B is a cross-sectional view of a part of the detergent supply unit 5 .

As shown in FIG. 31A , the end flow paths 26 b and 27 b ( FIGS. 16A and 16B ) of the water supply nozzles 12 and 13 extend toward positions offset from the water supply position K1 . Specifically, the end flow paths 26b and 27b extend toward the side wall 80 surrounding the water supply position K1 and the outer side wall 89 of the softener box 61. Therefore, water is discharged obliquely downward from the water supply nozzle 12 toward the side wall 80 of the tablet box 63 (arrow W1). Furthermore, water is discharged from the water supply nozzle 13 diagonally downward in the opposite direction toward the outer side wall of the softener box 61 on the opposite side (arrow W2).

The water touches the point P1 in the side wall 80 and the point P2 in the outer wall 89 of the softener box 61 and flows downward along the wall surface. Points P1 and P2 are located above the vertex of the tablet J and on the mesh 82 above the accommodation space K10. By water hitting the side wall 80 at points P1 and P2, the flow rate of the water can be reduced. After the collision, when the water flows downward along the wall, it will touch the side of the tablet J and be absorbed by the tablet J. Since the water indirectly touches the side of the tablet J after once colliding with the side wall 80 , compared with the case where the water directly touches the tablet J from the water supply nozzles 12 and 13 , the amount of water touching the tablet J can be reduced. The force of the water decreases.

In addition, after the impact, part of the water flowing downward will flow out of the tablet box 63 through the mesh 82 . Therefore, the amount of water reaching tablet J can be reduced, further reducing the force of the water.

Part of the water may also touch the tablet J by bouncing off the wall.

As shown in FIG. 31B , the height of the outer side wall 89 of the softener box 61 is lower than the height of the side wall 80 . The front ends of the water supply nozzles 12 and 13 are higher than the upper part of the outer side wall 89 and lower than the upper part of the side wall 80 .

In the flow path member 11 , a protruding portion 11 a protruding downward toward the hook portion 80 a is provided outside the tablet box 63 . Therefore, a labyrinth structure is formed by the protruding portion 11a and the side wall 80. With this structure, it is possible to suppress water from flowing from the detergent box 60 toward the tablet box 63 when water is supplied to the lotion box 60 through the path F1. Likewise, it is possible to suppress water from flowing from the tablet box 63 toward the lotion box 60 at the time when water is supplied to the tablet box 63 through the path F2.

Since water is supplied to the softener box 61 at the same time as the tablet box 63 , the labyrinth structure does not need to be formed by the upper part of the outer side wall 89 . [action]

Next, the operation of the washing machine 1 when executing the sterilization process will be described with reference to FIG. 31C . FIG. 31C is a sequence diagram of the sterilization process.

The sterilization process refers to a washing process performed to remove bacteria attached to clothing or towels. In one sterilization cycle, use 1 tablet J. It is assumed that after the sterilization process is completed, the tablet J does not remain in the tablet box 63 in the same shape as before being inserted. Therefore, the user will put new tablets J into the tablet box 63 before the next sterilization cycle.

As shown in FIG. 31C , the sterilization process includes a laundry process, a first cleaning process, a second cleaning process, and a dehydration process. In the washing process, detergent is supplied to the washing tub 4 , and in the washing process, other liquids, tablets, and the like are supplied to the washing tub 4 . In Embodiment 1, the tablet J is supplied to the washing tank 4 in the first washing step. When the softening agent is also supplied, the softening agent is supplied to the washing tub 4 in the second washing step.

First, the user puts the lotion and one tablet J used for one sterilization cycle into the manual input unit 6 . The user inserts the tablet J into the input port 63a. The input port 63a is not located near the end of the manual input unit 6, but is located between the input port 65a and the input port 66a. Therefore, even if the tablet J is accidentally dropped from the hand, the tablet J can be prevented from falling directly into the washing tub 4 .

In addition, by providing restriction portions (guide portions 68 and 168) on the detergent box 60 and the softener box 61 on the left and right sides of the input port 63a, even if the tablet J is mistakenly dropped from the hand to the left and right sides of the input port 63a, it will still be The card is hung on either of the left and right guide parts 68, 168. Therefore, erroneous insertion into the lotion box 60 or the softener box 61 can be prevented, and the tablets J can be inserted into the tablet box 63 more reliably. When the tablet J is inserted into the input port 63a, the tablet J will continue to roll toward the rear side L2 along the inclined surface 84, and will be more reliably arranged at the water supply position K1 (that is, the accommodation space K10).

On the other hand, the detergent can also be automatically injected by the automatic injection unit 7 . ＜Laundry process＞

In the washing process, the control unit C opens the water supply valve 10a to supply water to the path F1. The water flows into the detergent box 60 through the path F1 and is supplied to the washing tub 4 together with the detergent contained in the detergent box 60 . The control unit C stirs the washing tub 4 to wash the laundry. ＜1st cleaning process＞

Next, in the first washing step, the control unit C drains the water in the washing tub 4 containing the detergent, and supplies new water to the washing tub 4 through the path F1. The control unit C performs water supply until the water level of the washing tub 4 reaches the first predetermined water level. The first predetermined water level is assumed to be a water level required for immersing the laundry in water. The first predetermined water level can also be calculated by the control unit C based on the weight of the laundry obtained in advance. For example, the first predetermined water level is a water level at which the liquor ratio becomes 10L/kg in response to the weight of the laundry calculated by the control unit C.

Next, the control unit C closes the water supply valve 10a and opens the water supply valve 10b to supply a small water supply amount to the path F2 (hereinafter referred to as a preliminary water supply step). The water flows into the tablet box 63 through the path F2, and indirectly touches the tablet J as shown in FIG. 31A. A small water supply amount means an amount of water supply that moistens the surface of the tablet J, but is not sufficient to dissolve the tablet J and cause it to flow out of the tablet box 63 .

Here, the water supply amount in the preliminary water supply step is smaller than the water supply amount in the subsequent main water supply step. In the preliminary water supply step, the small amount of water supply supplied from the water supply valve 10b may be 400 mL or more and 2500 mL or less, preferably 400 mL or more and 1250 mL or less. The flow rate of water supplied through the water supply valve 10b may be 5 L/min or more and 15 L/min or less. About 15% of the water supplied from the water supply valve 10b is distributed to the tablet box 63, and for example, 50 mL or more and 200 mL or less of water flows into the tablet box 63. For example, when 1000 mL of water is supplied from the water supply valve 10 b at 12 L/min for 5 seconds, 140 mL of water flows into the tablet box 63 . The water supply time can be less than 10 seconds, preferably about 5 seconds.

Next, after the preliminary water supply step, the control unit C closes the water supply valve 10b and starts the standby time. The waiting time is the time during which the water supply from the water supply valve 10b to the path F2 is stopped. For example, the standby time is more than 20 seconds.

By setting the standby time, the time for the wet tablet J to foam in the preliminary water supply step can be ensured. In addition, time for the water to be supplied can be ensured to further penetrate from the surface of the tablet J to the inside. Tablet J that has been foamed or tablet J that has water penetrated inside becomes easily soluble in water. By performing the formal water supply step on the easily soluble tablet J, the tablet J can be easily and completely dissolved compared to the case where the formal water supply step is suddenly performed.

During the standby time, drainage, water supply using other paths F1 and F3, or stirring of the washing tank 4 can also be performed. In Embodiment 1, during the waiting time, the control unit C supplies water through the path F1 until the water level of the washing tub 4 reaches the second predetermined water level. The second predetermined water level may be a higher water level than the first predetermined water level.

Next, the control unit C opens the water supply valve 10b to supply water to the path F2 (hereinafter referred to as the main water supply step). The water flows into the tablet box 63 through the path F2, and indirectly touches the tablet J as shown in FIG. 31A. Since the water supply amount is more than the preliminary water supply step, Tablet J will be dissolved. The dissolved tablet J will be supplied to the washing tank 4 through the mesh 82 together with water.

The water supply amount in the main water supply step may be 30 L of water supply, or may be water supply for 120 seconds or more, for example, 30 times the water supply amount in the preliminary water supply step. ＜Second cleaning process＞

Next, in the second cleaning step, the control unit C drains the water in the washing tank 4 containing the melted tablet J, supplies new water to the washing tank 4 through the path F2, and stirs the washing tank 4. In Embodiment 1, the softening agent is supplied in the second cleaning step. The softener is supplied not by the manual injection unit 6 but by the automatic injection unit 7 . Since the manually inserted softener box 61 and the tablet box 63 share the path F2, if you want to supply softener through the manual input unit 6, it will be difficult to supply the softener and tablets separately, and there may be softening. There is a risk of mixing tablets and tablets. When softener is mixed with Tablet J, the tablet may not work as intended. On the other hand, if the softener and the tablet J can be fed separately, the tablet J can be supplied to the washing tank 4 in the first cleaning step, and the tablet J can be supplied to the washing tank 4 in the final cleaning step (that is, the second cleaning step). Supply softener to washing tank 4. Since the laundry can be washed in the second cleaning step after the tablet J is supplied in the first cleaning step, adhesion of the tablet J to the laundry can be further suppressed. Since the dehydration process can be started immediately after supplying the softening agent to the washing tub 4, compared with a case where a washing process is provided after supply, the components and aroma attached to the laundry can be maintained. Therefore, the control unit C supplies the softener through the automatic injection unit 7 . ＜Dehydration process＞

Next, in the dehydration process, the water in the washing tub 4 is drained, and the laundry is dehydrated.

By repeating the above operation, the dissolved residue of the tablet J may accumulate in the tablet box 63 . Therefore, the tablet box 63 must be removed from the washing machine 1 and the tablet box 63 must be maintained.

First, the detergent supply unit 5 is removed from the washing machine 1 .

Using the convex portion 81c of the gripping portion 81b as a mark, the position of the gripping portion 81b is identified, and the tablet box 63 is lifted from the main body 64 by placing a finger on the gripping portion 81b.

When the tablet box 63 is taken out, the opposing state between the side wall 80 and the outer wall 89 will be released, so that the inner wall of the tablet box 63 is exposed and can be easily accessed by the user. Pour water on the inner wall of the tablet box 63 to clean it. You can also use a brush or other tools to wipe off the dissolved residue of Tablet J attached to the inner wall. Here, the places where dissolution residues of the tablet J are likely to occur are the mesh 82 around the accommodating space K10, the bottom wall 86 in the water supply position K1, the inclined surface 84 with which the tablet J comes into contact, the protruding portion 87, and the protruding portion. 88. When the dissolved residue of the tablet J is generated on the mesh 82 , the openings of the mesh 82 may be clogged, thereby reducing the drainage performance of the tablet box 63 . However, in this disclosure, since the opposing state of the side wall 80 and the outer wall 89 can be released to access the inner wall of the tablet box 63, the mesh 82 can be easily cleaned to remove the tablet J. [Summary]

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

The washing machine 1 of Embodiment 2 has a tablet box, a lotion box, and a softener box. The tablet box is used for manually inserting tablets J for sterilization. The lotion box and the softener box are used for manually inserting liquid. agent.

Since Tablet J is a solid treatment agent, it is more likely to remain in the box without being completely dissolved in water than liquid or powder lotion. When the tablet J remains in the box, the number of tablets J used for sterilizing the laundry will decrease, resulting in a reduction in the sterilizing performance of the tablet J on the laundry. Therefore, there is a demand for appropriate water supply for tablet J to dissolve it.

In order to perform appropriate water supply, first, it is required to correctly insert the tablet J into the tablet box 63 . On the other hand, since the boxes are adjacent to each other due to the space saving of the manual insertion unit 6, there is a risk that the user may insert the tablets J into the detergent box 60 or the softener box 61 by mistake. In this case, the tablet J may be supplied to the washing tub 4 at the wrong time, causing damage to the clothes.

Therefore, since the insertion openings 65a and 66a of the detergent box 60 and the softener box 61 become smaller than the tablet J, even if the user mistakenly inserts the tablet J, the tablet J can still be suppressed. J reaches the bottom of the box. Therefore, the user can easily take out the tablet J from the wrong insertion destination and insert it into the correct insertion port 63a.

When the tablet J is inserted into the tablet box 63, the tablet J can pass through the insertion opening 63a when placed vertically, but becomes difficult to pass through the insertion opening 63a when placed horizontally. With this structure, the tablet J can move and roll in the tablet box 63 . Therefore, the tablet J can be easily rolled on the inclined surface 84 and the protruding portion 87 to guide the tablet J to the accommodation space K10. Moreover, it is held by the protruding part 88 so that it may not roll away from the accommodating space K10. With this structure, the tablet J can receive an appropriate water supply in the accommodation space K10.

After the tablet J is easily arranged and held in the accommodation space K10, water can be indirectly brought into contact with the tablet J in the accommodation space K10. Specifically, by directing the end flow paths 26b and 27b of the water supply nozzles 12 and 13 toward the wall surrounding the accommodation space K10, the water can be indirectly brought into contact with the tablet J. Therefore, compared with the case where water directly contacts the tablet J, it is possible to suppress fragments from being scattered from the tablet J and adhering to the upper part of the tablet box 63 . Since it is difficult to wash off the debris adhering to the upper part of the tablet box 63, there is a risk that the debris may remain in the tablet box 63. Therefore, while sufficient water supply is provided through this water supply structure, water is indirectly contacted with the tablet J, and the proportion of one tablet J that is supplied to the washing tank 4 increases, thereby improving the sterilization performance. stability.

In addition, in the sequence of water supply, after the tablet J is in a state in which the tablet J can be easily dissolved by performing the preliminary water supply step, the main water supply step is performed. Therefore, the tablet J can be further suppressed from remaining in the tablet box 63 .

Even if the tablet J is dissolved and remains in the tablet box 63 , the tablet box 63 having a one-sided open structure is easy to maintain, so the dissolved residue can still be removed. By using the softener box 61 to form one of the side walls of the tablet box 63, as long as the tablet box 63 is removed from the main body 64, the inner wall of the side wall 80 can be exposed, and the tablets J accumulated there can be removed. Wash away the dissolved residue. Therefore, the dissolved residue of the tablet J is suppressed from clogging the mesh 82 and the like to hinder the passage of the tablet J, and the proportion of one tablet J supplied to the washing tank 4 is further increased, thereby stabilizing the sterilization performance. In addition, it is also possible to suppress the tablet J having sterilizing properties from remaining in the tablet box 63 for a long period of time and causing an adverse effect on the tablet box 63 .

With the one-sided open structure, the size of the tablet box 63 in the width direction K can be reduced. Therefore, the tablet box 63 can be configured in a limited space, and the detergent supply unit 5 can be space-saving. [Effect 1]

According to the washing machine 1 of Embodiment 2, the following effects can be exerted.

As described above, the washing machine 1 of this embodiment includes the washing tub 4 which is rotatably installed in the casing 2 and the detergent supply unit 5 which supplies detergent to the washing tub 4 . The detergent supply unit 5 has a detergent box 60 (first detergent box), a softener box 61 (second detergent box), and a tablet box 63 (solid agent box). The detergent box 60 is provided with an inlet 65 a (first detergent inlet) into which detergent (first detergent) can be put in, and the detergent is accommodated and supplied to the washing tub 4 . The softener box 61 is provided with an inlet 66 a (second detergent inlet) into which a softener (second detergent) different from detergent can be put in, and the softener box 61 accommodates the softener and supplies it to the washing tub 4 . The tablet box 63 is provided with an input port 63 a (solid agent input port) into which the tablet J (solid agent) can be inserted, and accommodates the tablet J and supplies it to the washing tub 4 . The input port 63a is arranged between the input port 65a and the input port 66a.

With this structure, by disposing the input port 63a between the input port 65a and the input port 66a, even if the user accidentally drops the tablet J above the input port 63a, the tablet J can still be stuck in the washing machine. Agent box 60 or softener box 61. Therefore, it is possible to suppress the tablet J from being supplied to the washing tub 4 at a timing unexpected by the manufacturer of the washing machine 1 .

The washing machine 1 of this embodiment is a washing machine that performs a washing process after the washing process, with the tablets J stored in the tablet box 63 or with the softener box 61 containing softener. The softener box 61 is configured to supply the softener contained therein to the washing tub 4 during the washing process. The tablet box 63 is arranged adjacent to the softener box 61 .

With this configuration, the tablet J is supplied from the manual input unit 6 instead of the liquid (ie, softener) normally supplied in the cleaning process. Therefore, by being adjacent to the softener box 61, Path F2 can be shortened.

In the washing machine 1 of this embodiment, the tablet box 63 has the accommodation space K10 defined by at least the side wall 80 (wall surface) of the tablet box 63 . The dimension D26 (width) in the width direction K (short side direction) of the accommodation space K10 is substantially the same size as the width D2 in the width direction of the input port 63a.

With this configuration, space can be saved in the width direction K of the tablet box 63 . Therefore, the path F2 can be shortened and the efficiency can be improved. In addition, since the size D26 of the accommodating space K10 is substantially the same size as the width D2 of the insertion port 63a, when the tablet J has a disk shape, the tablet J is inserted in a vertically placed posture and remains vertically placed. posture to accommodate.

In the washing machine 1 of this embodiment, the detergent box 60, the tablet box 63, and the softener box 61 are arrange|positioned adjacent to the width direction K (one direction). The tablet box 63 is installed so that the width direction K becomes the short side direction.

With this configuration, the tablet box 63 can be provided without increasing the horizontal cross-sectional area of the detergent supply unit 5 .

In the washing machine 1 of this embodiment, the shape of the input port 63a is a vertical shape long in the direction orthogonal to the width direction K.

With this configuration, when the tablet J has a disk shape, it can be smoothly inserted in the longitudinal position.

In the washing machine 1 of this embodiment, the detergent supply unit 5 is configured to be pulled out from the main body of the washing machine 1 . The tablet box 63 has an accommodating space K10 for accommodating tablets, and an opening 63b (opening portion) provided at the upper part of the tablet box 63 . The opening 63b exposes the accommodation space K10 when the detergent supply unit 5 is pulled out from the main body of the washing machine 1 .

With this configuration, the inside of the accommodating space K10 can be visually confirmed from the opening 63b in a state where the detergent supply unit 5 has been pulled out. Therefore, the user can be prevented from inserting a plurality of tablets J by mistake.

In the washing machine 1 of this embodiment, the tablet box 63 has the inclined surface 84 (guide part) which guides the tablet J from the insertion port 63a to the storage space K10. The opening 63b is provided above the accommodation space K10.

With this structure, the tablet J can be put into the accommodation space K10 more reliably, and this can be visually confirmed from the opening 63b.

The washing machine 1 of this embodiment is equipped with the washing tub 4 rotatably installed in the housing 2, and the detergent supply unit 5 which supplies detergent to the washing tub 4. The detergent supply unit 5 has a detergent box 60 (first detergent box) and a tablet box 63 (solid agent box). The detergent box 60 is provided with an inlet 65 a (first detergent inlet) into which detergent (first detergent) can be put in, and the detergent is accommodated and supplied to the washing tub 4 . The tablet box 63 is provided with an inlet 63 a (solid agent inlet) into which water-soluble tablets J (solid agent) can be put in, and the tablets J are accommodated and supplied to the washing tub 4 . The detergent box 60 is provided with an accommodating portion 77 (detergent accommodating portion) for accommodating the detergent, and a guide portion 68 (restricting portion) for restricting the passage of the tablet J.

With this structure, the tablet J can be suppressed from being erroneously inserted into the insertion openings 65a and 66a. Moreover, even when the tablet J is inserted by mistake, it becomes difficult for the tablet J to pass through the insertion openings 65a and 66a. Therefore, it becomes easy to take out the accidentally inserted tablet J, and it becomes easy to insert the tablet J into the correct place again. By reinjection, the tablet J can reach the accommodation space K10 and receive water supply at an appropriate point in time.

In the washing machine 1 of this embodiment, the opening size D21 (width dimension of the maximum width) of the input port 65a is smaller than the dimension D3 in the longitudinal direction of the input port 63a.

With this configuration, the passage of the tablet J through the input port 65a can be restricted.

In the washing machine 1 of this embodiment, the guide part 68 (wall part) which defines the insertion port 65a functions as a restriction part.

With this configuration, there is no need to provide a separate restricting portion, and the passage of the tablet J through the input port 65a can be easily restricted by adjusting the opening size D21 of the input port 65a.

The washing machine 1 of this embodiment further has a softener box 61 (second detergent box), which is provided with an insertion port 66a (second detergent input port) into which softener (second detergent) can be inserted, and which accommodates the softener box 61 (second detergent box). The agent is supplied to the washing tank 4. The insertion port 63a is arranged between the lotion box 60 and the softener box 61.

With this configuration, the space between the detergent box 60 and the softener box 61 can be effectively utilized. Moreover, compared with the case where the insertion port 63a is arranged outside the detergent box 60 or the softener box 61, it becomes more difficult to drop the tablet J into the washing tub 4.

In the washing machine 1 of this embodiment, the insertion port 63a is arranged between the guide part 68 (wall part) provided in the detergent box 60 and the guide part 168 (wall part) provided in the softener box 61.

With this structure, since the insertion port 63a is disposed between the guide portion 68 and the guide portion 168, the tablet J accidentally dropped near the insertion port 63a becomes easily caught in the guide portions 68 and 168.

In the washing machine 1 of this embodiment, the tablet box 63 has an accommodation space K10 for accommodating the tablet J while holding the tablet J. The dimension D26 (width) of the accommodation space K10 in the width direction K is substantially the same size as the width D2 of the insertion port 63 a in the width direction K.

With this configuration, the width D2 in the width direction K of the insertion port 63a is made substantially the same as the thickness T0 of the tablet J, so that the tablet J can be inserted and accommodated in a vertical position. Since the tablet J can only be inserted in a determined posture, the user can be induced to carefully insert the tablet J. [Effect 2]

The washing machine 1 of this embodiment is a washing machine 1 configured to be able to insert water-soluble disposable tablets J (solid agent), and is provided with a washing tub 4, a tablet box 63 (solid agent box), and water supply nozzles 12 and 13. (Department of Water Supply). The washing tub 4 is rotatably arranged in the housing 2 . The tablet box 63 has an accommodation space K10 for accommodating the tablet J. The water supply nozzles 12 and 13 have discharge openings 24 and 25 through which water flows out, and water is supplied into the tablet box 63 through the discharge openings 24 and 25. The water supply nozzles 12 and 13 inject water toward the side wall 80 and the outer wall 89 (inner wall surface) of the predetermined accommodation space K10.

With this structure, the water discharged from the water supply nozzles 12 and 13 and directly touching the tablet J can be reduced. Therefore, it is possible to suppress fragments from scattering from the tablet J and to prevent water from adhering to a hard-to-reach place inside the tablet box 63 . Therefore, fragments of the tablet J are suppressed from remaining in the tablet box 63 after water supply, and the sterilization performance in the washing machine 1 can be improved.

In the washing machine 1 of this embodiment, the accommodation space K10 is defined by a part of the side wall 80 and a part of the outer wall 89 . The water supply nozzles 12 and 13 inject water toward the side wall 80 and the outer side wall 89 above the accommodation space K10.

With this configuration, the tablet J adhering to the side wall 80 and the outer wall 89 can be washed away by the water discharged from the water supply nozzles 12 and 13 . In addition, with this configuration, the water discharged from the water supply nozzles 12 and 13 first touches the side wall 80 and the outer wall 89 before supplying water to the tablet J, so that the water discharged from the water supply nozzles 12 and 13 can be The force of the water decreases.

In the washing machine 1 of this embodiment, the dimension D26 (length) of the first side in the width direction K (short side direction) in the horizontal cross section constituting the accommodation space K10 is the dimension D26 (length) orthogonal to the first side in the vertical direction. The size of both sides is D27 (length) or less.

With this configuration, the horizontal cross-sectional area of the accommodation space K10 in which the tablet J is accommodated can be reduced. Therefore, it is difficult for the water poured from the water supply nozzles 12 and 13 to directly spill onto the tablet J before it touches the side wall 80 and the outer wall 89 . In addition, the tablet box 63 can be installed in a space-saving manner.

In the washing machine 1 of this embodiment, the dimension D27 of the second side is equal to or larger than the dimension D24 (length) of the third side in the longitudinal direction in the horizontal cross section constituting the accommodating space K10. The water supply nozzles 12 and 13 inject water toward the side wall 80 and the outer wall 89 above the second side.

With this structure, the tablet J can be brought into contact with water covering the longitudinal direction (ie, the diameter direction) of the tablet J, so the tablet J can be efficiently dissolved.

In the washing machine 1 of this embodiment, the inner wall surface includes the side wall 80 (first surface) which is the inner surface of the tablet box 63 . The side wall 80 is provided with a mesh 82 (drainage part) having a plurality of water holes for draining water in the tablet box 63 . The water supply nozzles 12 and 13 inject water toward the mesh 82 .

With this configuration, the tablet J adhering to the mesh 82 can be washed away. Furthermore, with this configuration, part of the water supplied from the water supply nozzle 12 is discharged from the mesh 82 before it contacts the tablet J.

In the washing machine 1 of this embodiment, the inner wall surface includes the outer wall 89 (second surface) that is different from the side wall 80 . The water supply nozzles 12 and 13 include the water supply nozzle 12 (first water supply part) that injects water toward the mesh hole 82 and the water supply nozzle 13 (the second water supply part) that injects water toward the outer wall 89 .

With this configuration, the tablet J attached to the side walls surrounding both sides of the accommodating space K10 can be washed away. Furthermore, compared to the case where the washing machine 1 has only one water supply nozzle, the tablet J can be brought into contact with water and the tablet J can be dissolved efficiently.

In the washing machine 1 of this embodiment, the water supply nozzle 12 and the water supply nozzle 13 are arranged in the front-rear direction L (the long side direction in the horizontal cross section of the accommodation space K10).

With this structure, water can be brought into contact with the tablet J efficiently. Even when the space in the width direction K is limited, the two water supply nozzles 12 and 13 can still be arranged efficiently in space, and the water supply nozzles 12 and 13 are not large, and the tablet box 63 can be made compact. .

In the washing machine 1 of this embodiment, the tablet box 63 is provided with a protruding portion 88 (holding portion) for holding the tablet J in the accommodation space K10.

With this configuration, the tablet J can be held in the accommodation space K10. Therefore, the tablet J can be maintained at a position where the water appropriately touches the tablet J. In other words, by providing the protruding portion 88, the space on the rear side L2 of the protruding portion 88 can be defined as the accommodation space K10.

In the washing machine 1 of this embodiment, the accommodating space K10 is located vertically below the discharge openings 24 and 25 .

With this configuration, the size of the tablet box 63 in the width direction K can be reduced compared to the case where the end flow paths 26 b and 27 b are arranged in the width direction K away from the accommodating space K10 . In addition, compared with the case where the end flow paths 26b and 27b are arranged away from the accommodation space K10 in the front-rear direction L, the distance between the end flow paths 26b and 27b and the tablet J is reduced, and the water becomes Lozenge J has to be easily reached.

The washing machine 1 of this embodiment is provided with a main body part 64 (box accommodating part), which accommodates a softener box 61 (first detergent box) and a tablet box 63. The softener box 61 accommodates softener (first detergent box). agent); and path F2 (flow path), which is provided above the main body part 64 and supplies water to the main body part 64. The tablet box 63 is arranged adjacent to the softener box 61 .

With this configuration, since the tablet box 63 and the softener box 61 are arranged nearby, the path for supplying water to the tablet box 63 and the path for supplying water to the softener box 61 can be made common. Therefore, since the components for inserting detergent can be concentrated in the main body portion 64, user convenience can be improved.

The washing machine 1 of this embodiment is equipped with the water supply valve 10b (1st water supply valve) which introduces water from the outside. The water supply valve 10b supplies water to the tablet box 63 and the softener box 61.

With this configuration, the structure of the water supply member 10 can be simplified by sharing the water supply valve 10b in the tablet box 63 and the softener box 61. Therefore, the manufacturing cost of the washing machine 1 can be reduced.

In the washing machine 1 of this embodiment, the tablet box 63 has an insertion opening 63 a for the user to insert the tablets J into the tablet box 63 . The tablet box 63 has an inclined surface 84 extending obliquely downward toward the accommodation space K10 below the insertion opening 63a.

With this configuration, the tablet J can be guided to the water supply position K1 so that the tablet J can receive appropriate water supply.

In the washing machine 1 of this embodiment, the tablet box 63 has a vertical wall portion 85 (wall portion) extending downward from the lower end of the inclined surface 84 and a bottom wall portion 86 extending laterally from the lower end of the vertical wall portion 85 . , and is set below the accommodation space K10.

With this configuration, a step can be formed below the inclined surface 84 . Through the formation of the gap, the volume of the tablet box 63 can be increased. Therefore, the water level in the tablet box 63 can be suppressed from rising, and the possibility of fragments of the tablet J floating on the inclined surface 84 can be reduced. Therefore, the tablet J can be prevented from remaining on the inclined surface 84 .

In the washing machine 1 of this embodiment, the tablet box 63 further has a protruding portion 87 protruding from the side wall 80 (wall surface) of the tablet box 63 at a position across the gap R21 (interval) from the lower end of the inclined surface 84 . The protrusion 87 is located between the inclined surface 84 and the accommodation space K10.

With this configuration, it becomes easier to more reliably guide the tablet J to the accommodation space K10 while shortening the inclined surface 84 . By shortening the inclined surface 84, the tablet J can be prevented from remaining on the inclined surface 84. Since the gap R21 is provided between the inclined surface 84 and the protruding portion 87, the water falls downward through the gap R21, so that the water and the fragments of the tablet J are difficult to rise to the inclined surface 84.

The washing machine 1 of this embodiment is configured so that disposable tablets J (solid tablets) having water solubility can be inserted. The washing machine 1 includes a washing tub 4, a detergent box 60, a tablet box 63 (solid agent box), a water supply valve 10a (a first water supply valve), a water supply valve 10b (a second water supply valve), and a control unit C. The washing tub 4 is rotatably arranged in the housing 2 . The lotion box 60 contains lotion. The tablet box 63 accommodates tablets J. The water supply valve 10a supplies water to the lotion box 60. The water supply valve 10b supplies water to the tablet box 63. The control unit C controls the water supply valve 10a and the water supply valve 10b to execute the washing process (first process). The washing process includes a preliminary water supply step, a standby step and a formal water supply step. In the preliminary water supply step, the tablet J is supplied with water through the water supply valve 10b. In the standby step, after the preliminary water supply step, water supply by the water supply valve 10b is stopped. In the main water supply step, after the standby step, the tablet J that has undergone the preliminary water supply step is supplied with water through the water supply valve 10b. The amount of water supplied in the preliminary water supply step is smaller than that in the formal water supply step.

With this structure, before the actual water supply step for dissolving the tablet J, the tablet J is moistened in the preliminary water supply step, foams during the waiting time, and becomes easily dissolved. Therefore, it becomes easy to completely dissolve Tablet J through the formal water supply step. Therefore, it is possible to suppress the incompletely dissolved tablet J from remaining in the tablet box 63 after the main water supply step.

In the washing machine 1 of this embodiment, the washing process includes a washing process of adding detergent and at least two washing processes. The formal water supply step is performed in one or more washing steps before the final washing step.

With this configuration, the tablet J adhering to the laundry can be more reliably washed away by performing the washing step after the actual water supply step of adding the tablet J. Therefore, discoloration of the laundry can be suppressed. In addition, when there are three or more washing steps, by performing the washing step between the step of adding the detergent and the step of adding the tablet J, it is possible to suppress the detergent remaining in the washing tub 4 after the washing step. Tablet J has an adverse effect on Tablet J.

In the washing machine 1 of this embodiment, the water supply amount in the preliminary water supply step is less than 1/10 of the water supply amount in the main water supply step.

With this configuration, it is possible to suppress the tablet J from dissolving and flowing into the washing tub 4 in the preliminary water supply step.

In the washing machine 1 of this embodiment, the preliminary water supply step is performed in a state where the water level in the washing tub 4 is equal to or higher than a predetermined water level.

With this configuration, even when the tablet J is dissolved and flows into the washing tub 4 in the preliminary water supply step, the tablet J can be suppressed from adhering to the laundry. Therefore, discoloration of the laundry can be suppressed. [Effect 3]

The washing machine 1 of this embodiment is equipped with the washing tub 4 which is rotatably installed in the casing 2, and the tablet box 63 (solid agent box) which has the capacity to accommodate the water-soluble tablet J (solid agent). Space K10 (solid agent storage place), and the tablet J dissolved in water is supplied to the washing tank 4. The tablet box 63 is detachably provided on the housing 2 . When the tablet box 63 is installed in the housing 2, the accommodation space K10 is defined by the opposing side wall 80 and the outer side wall 89 (wall surface). In a state where the tablet box 63 has been removed from the housing 2, the facing state of the side wall 80 and the outer wall 89 can be released.

With this structure, when the opposing state of the side wall 80 and the outer wall 89 is released, the inner surface of the side wall 80 becomes easily accessible, and the accumulated dissolved residue of the tablet J can be easily washed away.

In the washing machine 1 of this embodiment, the side wall 80 has the mesh 82 (drainage part) formed so that water can pass.

With this structure, by releasing the opposing state of the side wall 80 and the outer wall 89, the mesh 82 formed in the side wall 80 becomes easier to access, and the tablet J blocked in the mesh 82 can be easily washed away.

In the washing machine 1 of this embodiment, the side wall 80 and the outer wall 89 face each other in the width direction K (short side direction) of the accommodation space K10.

With this structure, the depth from the opening created by releasing the facing state to the inner surface of the side wall 80 is small. Therefore, the user can easily reach the inner surface of the side wall 80 and perform maintenance on the tablet box 63 easily.

In the washing machine 1 of this embodiment, the tablet box 63 forms an insertion opening 63a into which tablets J can be inserted. The width D2 of the input port 63a in the width direction K is substantially the same as the dimension D26 (width) of the accommodation space K10 in the width direction K.

With this structure, when the size of the inserted tablet J is almost the same as that of the insertion port 63a, the wide surface of the tablet J faces the side wall 80. The side wall 80 has a large area that can come into contact with the tablet J, and the dissolved residue of the tablet J is likely to accumulate. By releasing the facing state of the side walls 80, more accumulated dissolved residues of the tablet J can be washed away.

In the washing machine 1 of this embodiment, the tablet box 63 is arrange|positioned so that the short side direction of the accommodation space K10 becomes substantially horizontal.

With this structure, the tablet box 63 can be configured to be smaller in the horizontal direction after having a structure that allows easy access to the inner surface of the side wall 80 when the facing state is released.
