(Findings, etc. that formed the basis of this disclosure)
At the time the inventors came up with the present disclosure, a water-soluble solid agent containing sodium dichloroisocyanurate was known as a disinfectant technology for bath cleaning. The inventors took a cue from the technology of disinfectants for bath cleaning and came up with the idea of a washing machine that dispenses a single-use water-soluble solid agent to impart solid agent components to laundry. The inventors discovered that there are two issues to be solved in order to realize this idea. One problem is that it is necessary to prevent the solid agent from being erroneously supplied to the washing tub in an undissolved state. Another problem is that it is necessary to remove and clean the solid agent fragments that remain undissolved inside the case that houses the solid agent. In order to solve these problems, the inventors have constructed the subject matter of the present disclosure.

Next, the configuration of the manual input unit 6 will be described in more detail with reference to FIGS. 3 to 6. FIG. 4 is a perspective view of the manual input unit 6. FIG. 5 is a sectional view showing a state in which the case 63 and the input port members 65 and 66 are removed from the manual input unit 6. FIG. 6 is a perspective view showing a state in which the case 63 and the input port members 65 and 66 are removed from the manual input unit 6.

As shown in FIG. 3, the manual input unit 6 includes a main body portion 64. The main body portion 64 is a member held in the unit case 50 so as to be able to be pulled out in the front-rear direction L.

As shown in FIG. 4, the main body portion 64 accommodates inlet members 65 and 66 and a case 63 (hereinafter referred to as tablet case 63). Inlet members 65, 66 and tablet case 63 are removably housed in main body 64.

As shown in FIGS. 4 and 5, the main body portion 64 is provided with cases 60, 61, and 62 arranged in the width direction K in which laundry detergent is stored. As mentioned above, the case 60 (hereinafter referred to as detergent case 60) stores detergent, the case 61 (hereinafter referred to as softener case 61) stores softener, and the case 62 (hereinafter referred to as powder detergent case 62) stores detergent powder. to accommodate. In the main body portion 64, the detergent case 60 and the powder detergent case 62 are adjacent to each other. On the other hand, a space 67 is provided between the detergent case 60 and the softener case 61, and a tablet case 63 is arranged in the space 67.

As shown in FIG. 5, the softener case 61 has a storage space 78 that accommodates the softener and a liquid discharge channel 74. The liquid discharge channel 74 has a U-shape that extends upward from the suction port 74a, is folded back at the top of the softener case 61, and is connected to the bottom surface 78a of the storage space 78. The liquid agent discharge channel 74 sucks up the softener from the suction port 74a and discharges it from the opening 61a formed in the bottom surface 78a of the accommodation space 78.

The detergent case 60 has a storage space 77 for storing detergent and a liquid discharge channel 73. The liquid agent discharge channel 73 has a U-shape similarly to the liquid agent discharge channel 74.

When the inlet members 65, 66 cover the liquid agent discharge channels 73, 74, a flow path is formed between the inlet members 65, 66 and the liquid agent discharge channels 73, 74. With such a structure, when the liquid level in the cases 60, 61 exceeds a predetermined height, water and liquid agent can exceed the tops of the liquid agent discharge channels 73, 74. That is, until the water level exceeds a predetermined level by opening the water supply valve 10a or 10b and supplying water to the case 60 or 61, the detergent or softener will not flow out from the cases 60, 61 and the case will be closed. 60, 61. Furthermore, even after the water supply is stopped by closing the water supply valve 10a or 10b, a siphon phenomenon occurs in the flow path between the inlet members 65, 66 and the liquid discharge flow paths 73, 74. The liquid agent and water are discharged from the opening 60a or the opening 61a. Therefore, it is possible to prevent water from remaining in the case 60 or the case 61.

On the other hand, the powder detergent case 62 is not provided with a member forming an inlet, and is open upward over the entire top surface.

The tablet case 63 is a member that accommodates a water-soluble solid agent used in one sterilization washing course. When the solid agent is exposed to water, the solid agent is dissolved and the dissolved solid agent is supplied to the washing tub 4. Solid dosage forms are solid or hollow solids. For example, a solid dosage form is a solid material formed from compacted powder. A solid agent may also be referred to as a solid processing agent. In Embodiment 1, Tablet J will be described as an example of a solid drug.

Here, Tablet J contains a component that exhibits sterilization performance. Tablet J contains a water-soluble component and has a certain shape before water is added, but when exposed to water, it breaks down into small pieces and dissolves in water.

Regarding the constituent materials of Tablet J, Tablet J may contain a component that generates hypochlorous acid. In Embodiment 1, Tablet J contains sodium dichloroisocyanurate as a disinfecting component. Tablet J may further contain a component that reacts with water and effervesces.

Regarding the shape of the tablet J, the tablet J may have a shape that allows it to move to a predetermined position in the tablet case 63, for example, has an outer peripheral shape or contour that allows it to roll and move. In Embodiment 1, the tablet J has a disk shape (FIGS. 10A and 10B) in which the diameter D0 is larger than the thickness T0.

The tablets J put into the tablet case 63 may be specific tablets J that are expected to be used by the manufacturer of the washing machine 1. For example, tablet J may be one or more types of tablet J specified. Further, for example, the type of tablet J may be selected from a catalog or list stored in the control unit C.

The tablet case 63 forms an input port 63a for inputting the tablet J on the front side L1. When the tablet case 63 is placed in the main body 64, the input port 63a is located between the input ports 65a and 66a that are aligned in the width direction K.

The tablet case 63 is fixed by being caught on the wall of the main body 64 that defines the space 67. Specifically, the tablet case 63 has a hook portion 80a protruding toward the outside of the tablet case 63, a hook portion 81a, and a grip portion 81b. The grip portion 81b is caught on the main body portion 64.

As shown in FIG. 6, openings 60a, 61a, 62a, and 67a are provided in the bottom surface 64a of the main body portion 64 at positions corresponding to the cases 60, 61, and 62 and the spaces 67, respectively. When water is supplied from the water supply member 10 to each case 60, 61, 62, 63, the stored liquid agent flows out toward the washing tub 4 from each opening 60a, 61a, 62a, 67a together with the water.

7 and 8 are perspective views of the input port member 65. Although only the input port member 65 will be illustrated and explained below, the input port member 66 also has a similar structure. The input port member 66 has a guide portion 168 (FIG. 4) similarly to the guide portion 68 of the input port member 65.

As shown in FIGS. 7 and 8, the input port member 65 includes a guide portion 68, a guide portion 69, and an engaging portion 75. The guide portion 68 is a wall portion that defines the range of the input port 65a, and guides the liquid from around the input port 65a to the input port 65a. The guide portion 69 is a channel member extending downward from the input port 65a, and guides the liquid agent from the input port 65a into the interior of the input port member 65 (case 60). The engaging portion 75 is a channel member that covers the liquid agent discharge channel 73.

As shown in FIG. 7, when a user accidentally inserts a tablet J into the input port 65a, the guide portion 68 is provided in a direction that intersects with the traveling direction (arrow A1) of the tablet J that is about to pass through the input port 65a. Extends to. In the first embodiment, the guide portion 68 extends in the lateral direction with respect to the tablet J that is inserted in the vertical direction.

The opening size of the input port 65a defined in the guide portion 68 is smaller than the external size of the tablet J. The opening size is the maximum dimension across the input port 65a. More specifically, the diagonal length D1 of the input 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 inlet 65a. In the first embodiment, the input port 65a has a substantially rectangular or rounded rectangular shape. Therefore, if the tablet J is a disc, even if the dimensional difference between the length D1 and the diameter D0 is small, the tablet J will be difficult to fit into the slot 65a, and the tablet J will be easily collected from the vicinity of the slot member 65. Become.

The guide portion 68 that defines the input port 65a through which the tablet J is difficult to pass functions as a regulating portion. In this specification, the regulating section is a member that prevents the tablets J from accidentally reaching the washing tub 4. The restriction part has a structure that prevents the tablet J from entering when the tablet J inserted into the wrong case (that is, a case other than the tablet case 63) attempts to advance to the back of the case, for example, the storage space 77. . The restricting portion may be a narrowing of the passage, a protrusion protruding in a direction intersecting the direction in which the tablet J is traveling, a mesh, or the like. On the other hand, the regulating portion is configured so as to be unlikely to obstruct passage of the liquid agent normally introduced into the case.

As shown in FIG. 8, the guide section 69 guides the liquid agent introduced from the input port 65a to the detergent case 60. One side of the guide portion 69 is open, and the injected liquid agent is guided along the arrow A1. The guide portion 69 has a flat surface 69a at a position facing the input port 65a. Even if a portion of the tablet J is dissolved and becomes smaller and passes through the inlet 65a, the flat surface 69a receives the tablet J, thereby preventing the tablet J from reaching the bottom of the accommodation space 77 and becoming difficult to take out. can.

9A and 9B are perspective views of the tablet case 63. FIG. 9C is a plan view of the tablet case 63. FIG. 9D is a cross-sectional view of the tablet case 63 taken along line AA in FIG. 9C. 10A and 10B are perspective views of tablet J.

In Embodiment 1, the tablet case 63 has one side open structure including one side wall 80 and an open side surface on the opposite side.

As shown in FIG. 9A, on one surface of the side wall 80, a peripheral wall 81, a protrusion 87, a protrusion 88, a protrusion 83a, and a protrusion 83b protrude in the width direction K (lateral direction). It is set up to do so. The peripheral wall 81 protrudes from the outer periphery of the side wall 80 and forms the front surface, bottom surface, and back surface of the tablet case 63. The protrusions 87 and 88 are provided inside the peripheral wall 81. The protrusions 83a and 83b are provided at the upper part of the side wall 80.

As shown in FIG. 9B, a hook portion 80a is provided on the other surface of the side wall 80. The hook portion 80a protrudes in a direction opposite to the peripheral wall 81 (outside of the tablet case 63). By hooking the hook portion 80a onto the detergent case 60, the tablet case 63 is supported by the main body portion 64 (FIG. 5).

As shown in FIG. 9A, the top of the tablet case 63 and the surface facing the side wall 80 are open. In the first embodiment, the outer wall 89 (FIG. 9D) of the softener case 61 functions as the other side wall of the tablet case 63.

The side wall 80 has a mesh 82 that penetrates in the thickness direction (width direction K) of the side wall 80. The melted tablets J flow out from the mesh 82 together with water and are supplied to the washing tub 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 section below the input port 63a that is inclined downward toward the rear side L2 with respect to the horizontal direction. 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 a water supply position K1 at a position on the rear side L2 away from the lower end of the vertical wall portion 85.

Here, the water supply position K1 is the position of the bottom wall portion 86 where the tablet J is placed during water supply. The water supply position K1 is a position that is assumed to be reached after the tablet J is inserted.

The water supply position K1, together with the peripheral wall 81 and the protrusion 88, forms an accommodation space K10 that accommodates the tablets. The storage space K10 is an area where the tablet J is present when the tablet J is stored in the tablet case 63. The accommodation space K10 may be larger than the outer shape of the tablet J. In other words, the dimensions of the accommodation space K10 are defined so that the tablet J is contained in the accommodation space K10. In the first embodiment, the dimension D4 of the accommodation space K10 in the front-rear direction L is larger than the diameter D0 of the tablet J (FIGS. 10A and 10B). The accommodation space K10 has a vertically elongated shape that is long in the front-rear direction L when viewed from above in the vertical direction. In the first embodiment, the lateral direction of the accommodation space K10 is horizontal (width direction K). Specifically, the dimension D4 of the accommodation space K10 in the front-rear direction L is larger than the dimension D6 of the accommodation space K10 in the width direction K.

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 may be provided directly below the water supply nozzles 12 and 13. A dimension D7 of the accommodation space K10 in the vertical direction is larger than a dimension D6 of the accommodation space K10 in the width direction K. In the first embodiment, the vertical dimension D7 of the accommodation space K10 is equal to the dimension D4 of the accommodation space K10 in the front-rear direction L. The dimension D7 in the vertical direction may be larger than the dimension D4 in the longitudinal direction L.

Furthermore, a plurality of dot-shaped protrusions 92 are formed on the peripheral wall 81 around the accommodation space K10 so as to protrude in the width direction K and come into contact with the softener case 61. In the first embodiment, four protrusions 92 are formed and have a spherical shape. The four protrusions 92 are arranged so as to surround the accommodation space K10.

The end portion of the front side L1 of the peripheral wall 81 forms a hook portion 81a that is bent with respect to the front surface and protrudes toward the front side L1. An end portion of the rear side L2 of the peripheral wall 81 forms a grip portion 81b that is bent with respect to the back surface and protrudes toward the rear side L2.

The hook portion 81a and the grip portion 81b are hooked on the wall portion that defines the space 67 (FIG. 5). Furthermore, when removing the tablet case 63 from the main body part 64, the user can lift the tablet case 63 by grasping the grip part 81b. A pattern may be attached to the grip part 81b so that the user can easily recognize that the grip part 81b is a grippable member. In the first embodiment, a linearly extending convex portion 81c is formed on the upper surface of the grip portion 81b.

As shown in FIG. 9C, the protrusion 87 is provided between the lower end of the inclined surface 84 and the water supply position K1, with a gap R1 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 D5 of the gap R1 between the protrusion 87 and the inclined surface 84 is smaller than the diameter D0 of the tablet J. The protruding portion 87 may be inclined downward toward the rear side L2. The protrusion 87 may be formed along the slope 84 , for example, along an extension of the slope 84 .

The protrusion 87 is separated from the peripheral wall 81. A space R2 is formed below the protrusion 87 and between it and the peripheral wall 81.

The protrusion 88 is provided between the protrusion 87 and the water supply position K1 at a position spaced apart from the lower end of the protrusion 87. The protruding portion 88 functions as a holding portion that holds the tablet J in the storage space K10. Therefore, the protrusion 88 is provided at a height below the diameter D0 of the tablet J from the bottom wall 86. The protrusion 88 may extend in the vertical direction. Such a structure makes it easier to stably hold the tablet J in the storage space K10 compared to the case where the protrusion 88 extends in the front-rear direction L.

The protrusion 88 is apart from the peripheral wall 81 and is provided at a position with a gap R3 above the bottom wall 86. Therefore, the space R2 below the protrusion 87 and the accommodation space K10 communicate with each other through the gap R3 below the protrusion 88. By providing the gap R3, water supplied to the accommodation space K10 flows into the space R2 and is drained through the mesh 82 provided in the space R2. Therefore, a rise in the water level in the tablet case 63 can be suppressed. Furthermore, a gap R1 is provided between the inclined surface 84 and the protrusion 87. Even if the water level rises and water rides onto the protrusion 87, the water can fall into the space R2 through the gap R1. Therefore, it is possible to suppress the water from pushing the fragments of the tablet J up onto the inclined surface 84. Compared to the case where the slope 84 and the projection 87 are continuous, the area of the slope 84 and the projection 87 can be made smaller, and fragments of the tablet J remain on the slope 84 or the projection 87. can be suppressed.

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 between the vertical wall portion 85 and the bottom wall portion 86 has a curvature. Therefore, compared to the case where the corner has a small curvature, the corner is less likely to be clogged with fragments of the tablet J, and it is possible to suppress the undissolved portion of the tablet J.

As shown in FIG. 9D, the peripheral wall 81 protrudes from the side wall 80 toward the outer wall 89 of the softener case 61. Therefore, the outer wall 89 forms the other side wall of the tablet case 63. Side wall 80 and outer wall 89 face each other. On the other hand, when the tablet case 63 is removed from the main body 64, the outer wall 89 remains on the main body 64, so the opposing state between the side wall 80 and the outer wall 89 is automatically released. By releasing the opposing state, the inner wall of the tablet case 63 becomes easier to access, and the inner wall of the tablet case 63 can be easily cleaned and maintained.

The dimension of the peripheral wall 81 in the width direction K is smaller than the dimension of the side wall 80 in the front-rear direction L. That is, the width direction K in which the peripheral wall 81 projects is the transverse direction of the tablet case 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. Such a structure makes the inner wall surface of the side wall 80 more accessible and easier to clean. The mesh 82 is provided on the inner wall surface of the side wall 80, facing the side wall opening. Therefore, the mesh 82 can be easily accessed through the side wall openings, making cleaning and other maintenance easier.

The protrusions 83a and 83b correspond to the upper part of the outer wall 89. The protrusions 83a and 83b push back the outer wall 89 even if the outer wall 89 bulges outward when the main body 64 is molded. In other words, the protrusions 83a and 83b have a function of correcting the shape of the softener case 61. With such a structure, a space inside the tablet case 63 can be secured. By forming the protrusions 83a and 83b near the center of the tablet case 63, the deflection of the softener case 61 can be corrected over a wider range compared to the case where the protrusions 83a and 83b are provided at the ends of the tablet case 63 in the longitudinal direction L. Furthermore, when the softener case 61 is molded with resin, it is long in the front-rear direction L and therefore tends to swell in the width direction K. However, by providing the protrusions 83a and 83b, the parts molded with resin More suitable for use.

The protrusion 92 also hits the outer wall 89. Therefore, a gap R4 is formed between the peripheral wall 81 and the outer wall 89 of the softener case 61. With this structure, water is drained from between the peripheral wall 81 and the outer wall 89. By providing the gap R4 in the peripheral wall 81, it becomes possible to provide a drainage path other than the mesh 82 and to perform drainage even when the mesh 82 is clogged. Further, by providing the gap R4 in the peripheral wall 81, the tablet case 63 can be manufactured more easily than in the case where a gap is provided in the bottom wall portion 86. The dimension D6 of the gap R4 in the width direction K may be smaller than the opening size of the mesh 82. With such a structure, even when water passes through the gap R4, the function of the mesh 82 as a filter is not impaired.

Since the protrusion 92 has a spherical shape, the contact area with the softener case 61 can be reduced, and the friction between the tablet case 63 and the softener case 61 can be reduced. Therefore, the tablet case 63 can be easily removed.

As the protrusion 83a hits the outer wall 89, as shown in FIG. 9A, the protrusion 83a divides the upper opening of the tablet case 63 into an input port 63a on the front side L1 and an 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 inputting 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 checking whether the tablet J is inserted.

Returning to FIG. 3, when the main body portion 64 is pulled out from the unit case 50, the input port 63a is exposed over the entire surface. The input port 63a may have a vertically elongated shape, that is, the width D2 of the input port 63a may be smaller than the length D3 of the input port 63a in the front-rear direction L. On the other hand, when the main body portion 64 is pulled out from the unit case 50, a portion of the opening 63b is exposed. The user can see the inside of the tablet case 63 through the opening 63b and check whether the tablet J has already been inserted. The opening size of the exposed opening 63b may be smaller than the external size of the tablet J.

Furthermore, as shown in FIGS. 9A and 9B, the mesh 82 may be composed of ribs 82a and 82b extending in two intersecting directions. In the first embodiment, the mesh 82 includes a plurality of ribs 82a (FIG. 9A) extending in the lateral direction (front-back direction L) and a plurality of ribs 82b (FIG. 9B) extending in the longitudinal direction.

In the mesh 82, ribs 82a extending in the horizontal direction form the inner wall of the tablet case 63, and ribs 82b extending in the vertical direction form the outer wall of the tablet case 63. Since the supplied water first hits the ribs 82a extending in the horizontal direction, it becomes difficult for the water to flow downward, and more water is discharged to the outside of the tablet case 63 through the mesh 82. Therefore, the water level within the tablet case 63 can be maintained low. It is possible to prevent water from overflowing from the tablet case 63 and water containing fragments of the tablets J from overflowing from openings such as the input port 63a at the top of the tablet case 63. Furthermore, the low water level can prevent fragments of the tablets J from drifting ashore to the upper part of the tablet case 63 and remaining in the tablet case 63 without being dissolved.

As shown in FIGS. 10A and 10B, the tablet J has a disk shape, and has a diameter D0 and a thickness T0. FIG. 10A shows a posture in which the tablet J is placed vertically with the thickness direction perpendicular to the feeding direction A2. FIG. 10B shows a posture in which the tablet J is placed horizontally with the thickness direction parallel to the feeding direction A2. The vertical position is a position in which the vertical dimension is larger than the width direction (for example, thickness direction) dimension of the tablet J in the horizontal section. In order to accommodate vertically placed tablets J in the accommodation space K10, the vertical dimension D7 of the accommodation space K10 is larger than the width direction K dimension D6, and the longitudinal dimension D4 of the accommodation space K10 is also larger than the width direction dimension D6. K is larger than dimension D6 (FIG. 9A). In order to store the vertically placed tablets J in the storage space K10 by effectively utilizing the space, the dimension D4 in the front-rear direction L of the storage space K10 is approximately the same as the diameter D0 of the tablet J, and the dimension D6 in the width direction K. is approximately the same as the thickness T0 of the tablet J. Furthermore, the vertically placed posture is a posture in which the movable contour 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 mounting surface is the vertical posture.

In the first embodiment, the width D2 of the input port 63a is smaller than the diameter D0 of the tablet J and 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 inlet 63a in a vertical position. In other words, when the tablet J is placed horizontally, it becomes difficult for the tablet J to pass through the inlet 63a.

In order to input and store vertically placed tablets J into the tablet case 63 while effectively utilizing the space in the width direction K, the width D2 of the input port 63a should be approximately the same as the thickness T0 of the tablets J. be. That is, the width D2 of the input port 63a and the dimension D6 in the width direction K of the accommodation space K10 (FIG. 9A) are substantially the same.

As shown in FIG. 9C, when a vertically placed tablet J is inserted into the input port 63a, the tablet J rolls on the inclined surface 84 and the protrusion 87 and reaches the water supply position K1. Therefore, due to the arrangement of the protrusion 88, the tablet J is retained in the accommodation space K10.

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

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

FIG. 11 is a top view of the washing agent supply unit 5 with the lid 50a removed. As shown in FIG. 11, the three water supply valves 10a, 10b, and 10c (FIG. 3) of the water supply member 10 are connected to paths F1, F2, and F3 of the flow path member 11, respectively. Paths F1, F2, 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 detergent case 60 and the powder detergent case 62. Path F2 connected to water supply valve 10b forms a flow path for supplying water to softener case 61 and tablet case 63. The path F3 connected to the water supply valve 10c forms a flow path for supplying water to the automatic dosing unit 7. By supplying water to a plurality of cases through one route, the number of water supply valves in the water supply member 10 can be reduced and the configuration can be simplified.

The path F2 forms openings 14 and 15 facing the tablet case 63 and a plurality of openings 16 facing the softener case 61. When the water supply valve 10b is opened and communicated with the path F2, water flows into the tablet case 63 through the openings 14 and 15 (see arrow B). On the other hand, water that has exceeded the openings 14 and 15 then flows into the softener case 61 through the opening 16.

FIG. 12 is a sectional view of the washing agent supply unit 5. As shown in FIG. 12, 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 at the top of the tablet case 63. The water supply nozzles 12 and 13 are cylindrical members and form internal channels 26 and 27. Therefore, the water that has flowed into the openings 14 and 15 is discharged into the tablet case 63 through the internal channels 26 and 27.

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

FIG. 13 is an enlarged perspective view of the water supply nozzles 12 and 13. FIG. 14A is a cross-sectional view of the water supply nozzle 12. FIG. 14B is a sectional view of the water supply nozzle 13.

As shown in FIG. 13, the water supply nozzles 12 and 13 have similar shapes, and discharge openings 24 and 25 for discharging water are formed at their lower ends. The discharge openings 24 and 25 are inclined in a direction offset from the vertical direction. In other words, the plane passing through the discharge openings 24, 25 is inclined with respect to the horizontal. The discharge opening 24 is inclined in the opposite direction to the discharge opening 25.

As shown in FIG. 14A, the internal flow path 26 of the water supply nozzle 12 has a straight flow path 26a and an end flow path 26b. The straight channel 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 vertical direction. That is, the central axis C1 of the end flow path 26b is inclined with respect to the vertical direction.

In the first embodiment, the cross section of the end flow path 26b becomes narrower from 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 channel 26b flows so as to gather around the central axis C1, and is likely to be discharged from the discharge opening 24 in the direction along the central axis C1 (diagonally downward).

As shown in FIG. 14B, the internal flow path 27 of the water supply nozzle 13, like the internal flow path 26 of the water supply nozzle 12, has a straight flow path 27a and an end flow path 27b. The end passage 27b of the water supply nozzle 13 is inclined in the opposite direction to the end passage 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 such a structure, the water discharged from the discharge opening 25 is discharged to the opposite side to the water discharged from the discharge opening 24. This allows the tablet J to be wetted more uniformly from both sides. The inclination angles of the end flow path 26b and the end flow path 27b may be the same.

FIG. 15A is a schematic cross-sectional view of the tablet case 63 viewed from the front-rear direction L. FIG. 15B is a cross-sectional view of a portion of the washing agent supply unit 5.

As shown in FIG. 15A, the respective end channels 26b and 27b (FIGS. 14A and 14B) of the water supply nozzles 12 and 13 extend toward a position shifted from the water supply position K1. Specifically, the end channels 26b and 27b extend toward positions on the side wall 80 surrounding the water supply position K1 and the outer wall 89 of the softener case 61. Therefore, water is discharged obliquely downward from the water supply nozzle 12 toward the side wall 80 of the tablet case 63 (arrow W1). Further, water is discharged diagonally downward from the water supply nozzle 13 toward the outer wall of the fabric softener case 61 on the opposite side (arrow W2).

The water hits point P1 on the side wall 80 and point P2 on the outer wall 89 of the softener case 61, and flows downward along the wall surface. Points P1 and P2 are located above the apex of the tablet J and on the mesh 82 above the accommodation space K10. When the water collides with the side wall 80 at points P1 and P2, the flow velocity of the water can be reduced. After the collision, water flows downward along the wall surface, hits the side of the tablet J, and is absorbed by the tablet J. Since the water once collides with the side wall 80 and then indirectly hits the side surface of the tablet J, the force of the water hitting the tablet J can be reduced compared to when the water hits the tablet J directly from the water supply nozzles 12 and 13.

Further, after the collision, a portion of the water flowing downward passes through the mesh 82 and flows out from the tablet case 63. Therefore, the amount of water reaching the tablet J can be reduced and the force of the water can be further reduced.

Some of the water may bounce off the wall and hit the tablet J.

As shown in FIG. 15B, the height of the outer wall 89 of the softener case 61 is lower than the height of the side wall 80. The tips of the water supply nozzles 12 and 13 are higher than the top of the outer wall 89 and lower than the top of the side wall 80.

The flow path member 11 is provided with a protruding portion 11a that protrudes toward the lower hook portion 80a on the outside of the tablet case 63. Therefore, a labyrinth structure is formed by the protrusion 11a and the side wall 80. Such a structure suppresses water from flowing from the detergent case 60 to the tablet case 63 at the timing when water is supplied to the detergent case 60 through the path F1. Similarly, at the timing when water is supplied to the tablet case 63 through the path F2, water is prevented from flowing from the tablet case 63 to the detergent case 60.

Since the softener case 61 is supplied with water at the same timing as the tablet case 63, there is no need to form a labyrinth structure with the upper part of the outer wall 89.

[motion]
Next, with reference to FIG. 15C, the operation of the washing machine 1 when executing the sterilization course will be described. FIG. 15C is a sequence diagram of the sterilization course.

A sterilization course refers to a washing course performed to remove bacteria attached to clothing and towels. One tablet J is used in one sterilization course. After the sterilization course ends, it is assumed that the tablets J do not remain in the tablet case 63 in the same shape as before they were inserted. Therefore, the user inserts a new tablet J into the tablet case 63 before the next sterilization course.

As shown in FIG. 15C, the sterilization course includes a washing step, a first rinsing step, a second rinsing step, and a dehydration step. In the washing process, detergent is supplied to the washing tub 4, and in the rinsing process, other liquids, tablets, etc. are supplied to the washing tub 4. In the first embodiment, the tablets J are supplied to the washing tub 4 in the first rinsing step. If a softener is also supplied, the softener is supplied to the washing tub 4 in the second rinsing step.

First, the user inputs detergent and one tablet J for one sterilization course into the manual input unit 6. The user inserts the tablet J into the input slot 63a. The input port 63a is not located near the end of the manual input unit 6, and the input port 63a is 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.

Furthermore, by providing regulating parts (guide parts 68, 168) on the detergent case 60 and the softener case 61 on the left and right sides of the input port 63a, even if the tablet J is accidentally dropped from the hand to the left and right sides of the input port 63a, It gets caught on one of the guide parts 68, 168. Therefore, it is possible to prevent erroneous loading into the detergent case 60 or the softener case 61, and the tablets J can be loaded into the tablet case 63 more reliably. When the tablet J is put into the input port 63a, the tablet J rolls toward the rear side L2 along the inclined surface 84, and is more reliably placed in the water supply position K1 (namely, the accommodation space K10).

On the other hand, the detergent may be automatically dispensed by the automatic dispensing unit 7.

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

<First rinsing step>
Subsequently, in the first rinsing step, the control unit C drains the water containing detergent from the washing tub 4 and supplies new water to the washing tub 4 through the path F1. The control unit C supplies water until the water level of the washing tub 4 reaches a first predetermined water level. The first predetermined water level is the water level that is assumed to be necessary for the laundry to be immersed in water. The first predetermined water level may be calculated by the control unit C according to the weight of the laundry obtained in advance. For example, the first predetermined water level is a water level at which the bath ratio is 10 L/kg according to the weight of the laundry calculated by the control unit C.

Next, the control unit C closes the water supply valve 10a, opens the water supply valve 10b, and supplies a small amount of water to the path F2 (hereinafter referred to as a preliminary water supply step). Water flows into the tablet case 63 through the path F2 and indirectly hits the tablet J as shown in FIG. 15A. The small amount of water supplied means that while the surface of the tablet J is moistened, the amount of water supplied is insufficient to dissolve the tablet J and cause it to flow out of the tablet case 63.

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

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

By providing a standby time, it is possible to secure time for the tablets J moistened in the preliminary water supply step to foam. Further, it is possible to secure time for the pre-supplied water to further permeate into the inside of the tablet J from the surface thereof. The foamed tablet J or the tablet J in which water has penetrated into the inside is easily dissolved in water. By performing the main water supply step on the easily soluble tablet J, the tablet J can be easily dissolved, compared to the case where the main water supply step is suddenly performed.

During the standby time, drainage, water supply using other routes F1 and F3, or stirring of the washing tub 4 may be performed. In the first embodiment, during the standby 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 higher than the first predetermined water level.

Subsequently, the control unit C opens the water supply valve 10b and supplies water to the path F2 (hereinafter referred to as main water supply step). Water flows into the tablet case 63 through the path F2 and indirectly hits the tablet J as shown in FIG. 15A. Since the amount of water supplied is larger than that in the preliminary water supply step, the tablets J are dissolved. The melted tablets J are supplied to the washing tub 4 through the mesh 82 along with water.

The amount of water supplied in the main water supply step may be 30 L of water, or may be supplied for 120 seconds or more, and is, for example, 30 times the amount of water supplied in the preliminary water supply.

<Second rinsing step>
Subsequently, in the second rinsing step, the control unit C drains the water containing the melted tablets J from the washing tub 4, supplies new water to the washing tub 4 through the path F2, and agitates the washing tub 4. In the first embodiment, a softener is supplied in the second rinsing step. The supply of softener is performed not by the manual dosing unit 6 but by the automatic dosing unit 7. Since the manual feeding softener case 61 shares the path F2 with the tablet case 63, when trying to feed the fabric softener using the manual feeding unit 6, it is difficult to feed the fabric softener and the tablets separately. There is a possibility that it may be mixed with J. If the softener and Tablet J are mixed, it becomes difficult for the tablet to exhibit its ideal effect. On the other hand, when the softener and tablets J can be dispensed separately, the tablets J are supplied to the washing tub 4 in the first rinsing process, and the softener is supplied to the washing tub 4 in the final rinsing process (i.e., the second rinsing process). Can be supplied. Since the laundry can be rinsed in the second rinsing step after the tablets J are supplied in the first rinsing step, adhesion of the tablets J to the laundry can be further suppressed. Since the dehydration process can proceed immediately after supplying the softener to the washing tub 4, the components and fragrance attached to the laundry are maintained, compared to a case where a rinsing process is provided after the supply. Therefore, the control unit C supplies the softener using the automatic dosing unit 7.

<Dehydration process>
Subsequently, in the dewatering step, the water in the washing tub 4 is drained to dehydrate the laundry.

By repeating the above operation, undissolved tablets J may accumulate in the tablet case 63. Therefore, it is necessary to remove the tablet case 63 from the washing machine 1 and clean the tablet case 63.

First, remove the washing agent supply unit 5 from the washing machine 1.

Using the convex portion 81c of the gripping portion 81b as a landmark, the user recognizes the position of the gripping portion 81b, and lifts the tablet case 63 from the main body portion 64 by placing a finger on the gripping portion 81b.

When the tablet case 63 is taken out, the opposing state between the side wall 80 and the outer wall 89 is released, and the inner wall of the tablet case 63 is exposed and can be easily accessed by the user. The inner wall of the tablet case 63 is washed by spraying water on it. You may use a tool such as a brush to scrape off any undissolved tablets J adhering to the inner wall. Here, the locations where undissolved tablets J are likely to occur are the mesh 82 around the storage space K10, the bottom wall 86 at the water supply position K1, and the inclined surface 84, protrusion 87, and protrusion 88 that the tablet J comes into contact with. be. If undissolved tablets J remain on the mesh 82, the openings of the mesh 82 may become clogged and the drainage performance of the tablet case 63 may deteriorate. However, in the present disclosure, since the opposing state between the side wall 80 and the outer wall 89 is released and the inner wall of the tablet case 63 can be accessed, the mesh 82 can be easily cleaned and the tablet J can be removed.

[summary]
The features of the present disclosure will be described by summarizing the above description.

The washing machine 1 according to the first embodiment has a tablet case for manually loading the sterilizing tablets J, and a detergent case and a softener case for manually loading the liquid.

Since Tablet J is a solid processing agent, there is a greater possibility that it will not dissolve completely in water and remain in the case compared to liquid or powder detergents. When the tablets J remain in the case, the number of tablets J used for sterilizing the laundry decreases, and the sterilizing performance of the tablets J on the laundry decreases. Therefore, it is required to appropriately supply water to the tablets J to dissolve them.

In order to supply water appropriately, it is first necessary to put the tablets J into the tablet case 63 without fail. On the other hand, due to the space saving of the manual feeding unit 6, the cases are adjacent to each other, so there is a risk that the user may accidentally throw the tablets J into the detergent case 60 or the softener case 61. In this case, the tablets J are supplied to the washing tub 4 at the wrong timing, potentially damaging the clothes.

Therefore, since the input ports 65a and 66a of the detergent case 60 and the softener case 61 are smaller than the tablets J, even if the user inserts the tablets into the wrong place, the tablets J will not reach the bottom of the case. can be suppressed. Therefore, the user can easily take out the tablet J from the wrong input location and re-insert it into the correct input slot 63a.

When putting the tablet J into the tablet case 63, the tablet J can pass through the slot 63a in a vertical position, but it is difficult to pass through the slot 63a in a horizontal position. With such a configuration, the tablet J can roll and move within the tablet case 63. Therefore, it is easy to roll the tablet J on the inclined surface 84 and the protrusion 87 and guide it into the storage space K10. In addition, it is held by the protruding portion 88 so as not to roll away from the accommodation space K10. With such a structure, the tablet J can receive an appropriate water supply in the accommodation space K10.

Water can be indirectly applied to the tablets J in the storage space K10 while making it easier to arrange and hold the tablets J in the storage space K10. Specifically, water can be indirectly applied to the tablet J by directing the end channels 26b and 27b of the water supply nozzles 12 and 13 toward the wall surface surrounding the accommodation space K10. Therefore, compared to the case where water hits the tablet J directly, it is possible to suppress fragments from scattering from the tablet J and adhering to the upper part of the tablet case 63. Since it is difficult to wash off the fragments attached to the upper part of the tablet case 63, there is a possibility that the fragments remain in the tablet case 63. Therefore, by indirectly applying water to the tablet J while supplying sufficient water with such a water supply structure, the ratio of one tablet J supplied to the washing tub 4 increases, and the sterilization performance is stabilized. do.

Further, in the water supply sequence, a preliminary water supply step is performed to make the tablets J easily soluble, and then the main water supply step is performed. Therefore, it is possible to further suppress the tablets J from remaining in the tablet case 63.

Even if undissolved tablets J occur in the tablet case 63, the undissolved tablets can be removed because the tablet case 63, which has an open structure on one side, is easy to clean. By configuring one side wall of the tablet case 63 with the softener case 61, simply by removing the tablet case 63 from the main body 64, the inner wall of the side wall 80 is exposed and the undissolved tablets J accumulated there can be washed away. be able to. Therefore, undissolved tablets J are prevented from clogging the mesh 82 etc. and obstructing the passage of tablets J, and the proportion of one tablet J supplied to the washing tub 4 is further increased, resulting in stable sterilization performance. do. Furthermore, it is also possible to prevent the tablets J having sterilization performance from remaining in the tablet case 63 for a long period of time and adversely affecting the tablet case 63.

Due to the one-side open structure, the dimension of the tablet case 63 in the width direction K can be reduced. Therefore, the tablet case 63 can be configured in a limited space, and further, the space of the washing agent supply unit 5 can be saved.

[Effect 1]
According to the washing machine 1 according to the first embodiment, the following effects can be achieved.

As described above, the washing machine 1 of the present embodiment includes a washing tub 4 rotatably provided within the housing 2 and a washing agent supply unit 5 that supplies washing agent to the washing tub 4. The laundry agent supply unit 5 includes a detergent case 60 (first laundry agent case), a softener case 61 (second laundry agent case), and a tablet case 63 (solid agent case). The detergent case 60 is provided with an input port 65a (first laundry agent input port) into which detergent (first laundry agent) is input, and stores the detergent and supplies it to the washing tub 4. The softener case 61 is provided with an input port 66a (second laundry agent input port) into which a softener (second laundry agent) different from detergent is input, and stores the softener and supplies it to the washing tub 4. The tablet case 63 is provided with an input port 63a (solid agent input port) into which tablets J (solid agent) are input, and stores the tablets J and supplies them to the washing tub 4. The input port 63a is arranged between the input port 65a and the input port 66a.

With this configuration, by arranging the input port 63a between the input ports 65a and 66a, even if the user accidentally drops the tablet J above the input port 63a, the detergent case 60 or the softener Tablet J gets caught in case 61. Therefore, the tablets J can be prevented from being supplied to the washing tub 4 at a timing not intended by the manufacturer of the washing machine 1.

In the washing machine 1 of the present embodiment, after the washing process, the rinsing process is executed with the tablet case 63 containing the tablets J or with the softener case 61 containing the softener. It's a washing machine. The softener case 61 is configured to be able to supply the contained softener to the washing tub 4 during the rinsing process. The tablet case 63 is provided adjacent to the softener case 61.

With this configuration, the tablets J are supplied from the manual feeding unit 6 instead of the liquid agent (i.e., softener) that is normally supplied in the rinsing process. F2 can be shortened.

In the washing machine 1 of the present embodiment, the tablet case 63 has a storage space K10 defined by at least the side wall 80 (wall surface) of the tablet case 63. A dimension D6 (width) in the width direction K (lateral direction) of the accommodation space K10 is approximately the same size as a width D2 in the width direction of the input port 63a.

With such a configuration, it is possible to save space in the width direction K of the tablet case 63. Therefore, the route F2 can be shortened to improve efficiency. In addition, since the dimension D6 of the storage space K10 and the width D2 of the input port 63a are approximately the same size, when the tablet J has a disk shape, the tablet J is inserted in a vertical position, and the vertical position is maintained. will be accommodated.

In the washing machine 1 of this embodiment, the detergent case 60, the tablet case 63, and the softener case 61 are arranged adjacent to each other in the width direction K (one direction). The tablet case 63 is provided so that the width direction K is the width direction of the tablet case 63.

With such a configuration, the tablet case 63 can be provided without unnecessarily increasing the horizontal cross-sectional area of the washing agent supply unit 5.

In the washing machine 1 of this embodiment, the shape of the input port 63a is a vertically elongated shape that is long in the direction perpendicular to the width direction K.

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

In the washing machine 1 of this embodiment, the washing agent supply unit 5 is configured to be able to be pulled out from the main body of the washing machine 1. The tablet case 63 has a storage space K10 for storing tablets, and an opening 63b (opening) provided at the top of the tablet case 63. The opening 63b exposes the storage space K10 when the washing agent supply unit 5 is pulled out from the main body of the washing machine 1.

With such a configuration, the interior of the accommodation space K10 can be visually checked through the opening 63b when the washing agent supply unit 5 is pulled out. Therefore, it is possible to prevent the user from accidentally inserting a plurality of tablets J.

In the washing machine 1 of this embodiment, the tablet case 63 has an inclined surface 84 (guiding portion) that guides the tablet J from the input port 63a to the storage space K10. The opening 63b is provided above the accommodation space K10.

With such a configuration, the tablet J can be more reliably introduced into the accommodation space K10, and the situation can be visually confirmed from the opening 63b.

The washing machine 1 of this embodiment includes a washing tub 4 rotatably provided within a housing 2 and a washing agent supply unit 5 that supplies washing agent to the washing tub 4. The washing agent supply unit 5 includes a detergent case 60 (first washing agent case) and a tablet case 63 (solid agent case). The detergent case 60 is provided with an input port 65a (first laundry agent input port) into which detergent (first laundry agent) is input, and stores the detergent and supplies it to the washing tub 4. The tablet case 63 is provided with an input port 63a (solid agent input port) into which a water-soluble tablet J (solid agent) is input, and stores the tablet J and supplies the tablet J to the washing tub 4. The detergent case 60 is provided with an accommodation space 77 (laundry agent accommodation space) for accommodating detergent, and a guide part 68 (restriction part) for regulating the passage of the tablets J.

With such a configuration, it is possible to prevent the tablets J from being erroneously inserted into the input ports 65a and 66a. Further, even if the tablet J is inserted by mistake, the tablet J becomes difficult to pass through the input ports 65a and 66a. Therefore, it becomes easier to take out the tablet J that has been inserted by mistake, and it becomes easier to re-insert the tablet J into the correct place. By re-inserting, the tablet J reaches the storage space K10 and can receive water supply at an appropriate timing.

In the washing machine 1 of this embodiment, the opening size D1 (maximum width dimension) of the input port 65a is smaller than the longitudinal dimension D3 of the input port 63a.

With such a configuration, it is possible to restrict the tablet J from passing through the input port 65a.

In the washing machine 1 of this embodiment, the guide portion 68 (wall portion) that defines the input port 65a functions as a restriction portion.

With such a configuration, it is possible to easily restrict the passage of the tablet J through the input port 65a by adjusting the opening size D1 of the input port 65a without separately providing a regulating section.

The washing machine 1 of the present embodiment is provided with an input port 66a (second laundry agent input port) into which a softener (second laundry agent) is input, and a softener that stores the softener and supplies it to the washing tub 4. It further includes a laundry detergent case 61 (second laundry detergent case). The input port 63a is arranged between the detergent case 60 and the softener case 61.

With such a configuration, the space between the detergent case 60 and the softener case 61 can be effectively utilized. Moreover, it becomes difficult to drop the tablets J into the washing tub 4 compared to the case where the inlet 63a is arranged outside the detergent case 60 or the softener case 61.

In the washing machine 1 of the present embodiment, the inlet 63a is located between the guide portion 68 (wall portion) provided in the detergent case 60 and the guide portion 168 (wall portion) provided in the softener case 61. Placed.

With this configuration, since the input port 63a is disposed between the guide portion 68 and the guide portion 168, tablets J accidentally dropped near the input port 63a are likely to be caught in the guide portions 68, 168. .

In the washing machine 1 of the present embodiment, the tablet case 63 has a storage space K10 in which the tablets J are held and stored. A dimension D6 (width) in the width direction K of the accommodation space K10 is approximately the same size as a width D2 in the width direction K of the input port 63a.

With such a configuration, the width D2 of the input port 63a in the width direction K can be made approximately the same as the thickness T0 of the tablet J, and the tablet J can be loaded and stored in a vertical position. Since the tablet J can only be inserted in a predetermined posture, the user can be guided to carefully insert the tablet J.

[Effect 2]
The washing machine 1 of the present embodiment is configured to be able to load water-soluble single-use tablets J (solid dosage forms), and includes a washing tub 4 and a tablet case 63 (solid dosage form). ), and water supply nozzles 12 and 13 (water supply section). The washing tub 4 is rotatably provided within the housing 2. The tablet case 63 has a storage space K10 that stores the tablets J. The water supply nozzles 12 and 13 have discharge openings 24 and 25 through which water flows out, and supply water into the tablet case 63 through the discharge openings 24 and 25. The water supply nozzles 12 and 13 inject water toward the side wall 80 and outer wall 89 (inner wall surface) that define the accommodation space K10.

With such a configuration, water discharged from the water supply nozzles 12 and 13 and directly hitting the tablets J can be reduced. Therefore, it is possible to suppress fragments from scattering from the tablet J, and to prevent water from adhering to locations within the tablet case 63 that are difficult to reach. Therefore, it is possible to suppress fragments of the tablets J from remaining in the tablet case 63 after water is supplied, thereby improving the sterilization performance of the washing machine 1.

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

With such a configuration, the tablets 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. Furthermore, with such a configuration, the water discharged from the water supply nozzles 12 and 13 is applied to the side wall 80 and the outer wall 89 before being supplied to the tablet J, thereby reducing the water discharged from the water supply nozzles 12 and 13. You can slow down the momentum.

In the washing machine 1 of the present embodiment, the dimension D6 (length) of the first side constituting the width direction K (short side direction) in the horizontal cross section of the storage space K10 is the dimension D6 (length) of the first side that is perpendicular to the first side and the vertical direction. The dimension of two sides is D7 (length) or less.

With such a configuration, the horizontal cross-sectional area of the accommodation space K10 in which the tablets J are accommodated can be reduced. Therefore, water injected from the water supply nozzles 12 and 13 is less likely to directly hit the tablet J before hitting the side wall 80 and the outer wall 89. Further, the tablet case 63 can be provided in a space-saving manner.

In the washing machine 1 of the present embodiment, the dimension D7 of the second side is greater than or equal to the dimension D4 (length) of the third side constituting the longitudinal direction in the horizontal cross section of the storage space K10. The water supply nozzles 12 and 13 inject water upward from the second side of the side wall 80 and the outer wall 89.

With such a configuration, the tablet J can be brought into contact with water in the longitudinal direction (i.e., diametrical direction), so that the tablet J can be efficiently dissolved.

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

With such a configuration, the tablets J adhering to the mesh 82 can be washed away. Moreover, with such a configuration, a portion of the water supplied from the water supply nozzle 12 is discharged from the mesh 82 before hitting the tablet J.

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

With such a configuration, the tablets J attached to both side walls surrounding the storage space K10 can be washed off. Moreover, compared to the case where the washing machine 1 has only one water supply nozzle, the tablets J can be efficiently dissolved by applying water to the tablets J.

In the washing machine 1 of the present embodiment, the water supply nozzle 12 and the water supply nozzle 13 are lined up in the front-rear direction L (the longitudinal direction in the horizontal cross section of the accommodation space K10).

With such a configuration, water can be applied to the tablet J efficiently. Even when the space in the width direction K is limited, the two water supply nozzles 12 and 13 can be arranged spatially efficiently, the water supply nozzles 12 and 13 are not bulky, and the tablet case 63 is formed compactly. can.

In the washing machine 1 of this embodiment, the tablet case 63 is provided with a protrusion 88 (holding part) that holds the tablet J in the storage space K10.

With such a configuration, the tablet J can be held in the storage space K10. Therefore, the tablet J can be held in a position where the water hits the tablet J appropriately. In other words, by providing the protrusion 88, the space on the rear side L2 of the protrusion 88 is defined as the accommodation space K10.

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

With such a configuration, the dimension of the tablet case 63 in the width direction K can be reduced compared to the case where the end channels 26b and 27b are arranged at a position apart from the accommodation space K10 in the width direction K. Furthermore, the distance between the end channels 26b, 27b and the tablet J is reduced compared to the case where the end channels 26b, 27b are arranged at a position away from the housing space K10 in the front-rear direction L. Water can easily reach tablet J.

The washing machine 1 of the present embodiment includes a main body part 64 (case storage part) that contains a softener case 61 (first washing agent case) and a tablet case 63, which contain a softener (first washing agent). A path F2 (flow path) is provided above the section 64 and supplies water into the main body section 64. The tablet case 63 is provided adjacent to the softener case 61.

With this configuration, the tablet case 63 and the softener case 61 are placed close to each other, so that the route for supplying water to the tablet case 63 and the route for supplying water to the softener case 61 can be made common. can. Therefore, the member for introducing the washing agent can be integrated into the main body portion 64, thereby improving convenience for the user.

The washing machine 1 of this embodiment includes a water supply valve 10b (first water supply valve) that introduces water from the outside. The water supply valve 10b supplies water to the tablet case 63 and the softener case 61.

With such a configuration, the tablet case 63 and the softener case 61 share the water supply valve 10b, thereby simplifying the structure of the water supply member 10. Therefore, the manufacturing cost of the washing machine 1 can be reduced.

In the washing machine 1 of this embodiment, the tablet case 63 has an input port 63a through which the user inserts the tablets J into the tablet case 63. The tablet case 63 has an inclined surface 84 extending diagonally downward toward the storage space K10 below the input port 63a.

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

In the washing machine 1 of the present embodiment, the tablet case 63 includes a vertical wall portion 85 (wall portion) extending downward from the lower end of the inclined surface 84, and a vertical wall portion 85 (wall portion) extending laterally from the lower end of the vertical wall portion 85 to form the storage space K10. It has a bottom wall part 86 provided below.

With such a configuration, a step can be formed below the inclined surface 84. By forming the step, the volume of the tablet case 63 can be increased. Therefore, it is possible to suppress the rise in the water level in the tablet case 63 and reduce the possibility that fragments of the tablets J will drift ashore on the inclined surface 84. Therefore, it is possible to prevent the tablet J from remaining on the inclined surface 84.

In the washing machine 1 of the present embodiment, the tablet case 63 further includes a protrusion 87 that protrudes from the side wall 80 (wall surface) of the tablet case 63 at a position spaced apart from the lower end of the inclined surface 84 by a gap R1. . The protrusion 87 is located between the inclined surface 84 and the accommodation space K10.

With such a configuration, it becomes easier to more reliably guide the tablet J to the storage space K10 while shortening the inclined surface 84. By shortening the inclined surface 84, it is possible to prevent the tablet J from remaining on the inclined surface 84. Since the gap R1 is provided between the inclined surface 84 and the protrusion 87, water can drop down through the gap R1, so water and fragments of the tablet J are less likely to rise to the inclined surface 84.

The washing machine 1 of the present embodiment is configured to be able to load water-soluble, single-use tablets J (solid tablets). The washing machine 1 includes a washing tub 4, a detergent case 60, a tablet case 63 (solid medicine case), a water supply valve 10a (first water supply valve), a water supply valve 10b (second water supply valve), and a control unit C. Equipped with. The washing tub 4 is rotatably provided within the housing 2. The detergent case 60 stores detergent. The tablet case 63 accommodates the tablets J. The water supply valve 10a supplies water to the detergent case 60. The water supply valve 10b supplies water to the tablet case 63. The control unit C controls the water supply valve 10a and the water supply valve 10b to execute a washing process (first process). The washing process includes a preliminary water supply step, a standby step, and a main water supply step. In the preliminary water supply step, water is supplied to the tablets J by the water supply valve 10b. In the standby step, water supply by the water supply valve 10b is stopped after the preliminary water supply step. In the main water supply step, water is supplied by the water supply valve 10b to the tablets J that have undergone the preliminary water supply step after the standby step. The amount of water supplied in the preliminary water supply step is less than the amount of water supplied in the main water supply step.

With this configuration, before the main water supply step for dissolving the tablets J, the tablets J are moistened in the preliminary water supply step and foamed during the standby time, making them easier to dissolve. Therefore, the main water supply step makes it easy to completely dissolve the tablet J. Therefore, it is possible to prevent undissolved tablets J from remaining in the tablet case 63 after the main water supply step.

In the washing machine 1 of the present embodiment, the washing process includes a washing process in which detergent is added, and at least two rinsing processes. This water supply step is performed in one or more rinse steps before the final rinse step.

With such a configuration, by performing the rinsing step after the main water supply step in which the tablets J are introduced, the tablets J adhering to the laundry can be washed off more reliably. Therefore, discoloration of laundry can be suppressed. In addition, when there are three or more rinsing steps, by performing the rinsing step between the step in which detergent is added and the step in which tablets J are added, detergent remaining in the washing tub 4 after the washing step can be removed. can be suppressed from having an adverse effect on Tablet J.

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

With such a configuration, it is possible to prevent the tablets J from dissolving and flowing into the washing tub 4 during the preliminary water supply step.

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

With such a configuration, even if the tablets J dissolve and flow into the washing tub 4 in the preliminary water supply step, it is possible to prevent the tablets J from adhering to the laundry. Therefore, discoloration of laundry can be suppressed.

[Effect 3]

The side wall 80 is made up of the tablet case 63 and has a mesh 82 (drainage section) formed to allow water to pass therethrough. The outer wall 89 is composed of a softener case 61.

With such a structure, simply by removing the tablet case 63 from the washing machine 1, the opposing state between the side wall 80 and the outer wall 89 can be released.

In the washing machine 1 of this embodiment, the tablet case 63 has a peripheral wall 81 facing the softener case 61. The peripheral wall 81 has a projection 92 that projects toward the softener case 61.

With such a structure, a gap R4 can be provided between the peripheral wall 81 and the softener case 61, and the drainage performance of the tablet case 63 can be improved. Therefore, it is possible to suppress the rise in the water level in the tablet case 63, and it is possible to suppress fragments of the tablets J from drifting ashore to the upper part of the tablet case 63 and remaining undissolved.

In the washing machine 1 of this embodiment, the path F2 (water supply path) between the softener case 61 and the tablet case 63 is common.

With such a structure, the structure of the route F2 can be simplified. In the washing machine 1 having the path F2, by providing the automatic loading unit 7, the softener can be supplied to the washing tub 4 during the sterilization course.
