<Manual loading case 11c and detergent loading hole 17a (see Figure 10)>
FIG. 13A shows a perspective view of the manual input case 11c viewed diagonally from the upper right front. FIG. 13B shows a top view of the manual input case 11c viewed from above.
As described above, the manual loading case 11c includes the manual detergent loading case 11d and the softener loading manual case 11e.
The manual detergent injection case 11d is formed in the shape of a concave case that is vertically elongated in the front-rear direction and has a bottom plate 11d3 that is inclined so that the back side is located downward. A grid portion 11d2 having a cutout 11d1, which is a hole, is formed on the back side of the manual detergent injection case 11d.
As a result, when powdered detergent, liquid detergent, or bleach is put into the detergent injection manual case 11d, the powdered detergent, liquid detergent, or bleach moves on the bottom plate 11d3 toward the cutout 11d1 of the grid portion 11d2. This allows the powder detergent, liquid detergent, and bleach to fall smoothly from the cutout 11d1 of the grid portion 11d2.

Like the manual detergent dispenser case 11d, the manual softener dispenser case 11e is formed in the shape of a vertically elongated concave case in the front-rear direction and has a bottom plate 11e3 that is inclined so that the back side is located downward. A siphon portion 11e1 for supplying the softener to the water quality/temperature/detergent detection tank 6k and the outer tank 6 using a siphon is configured on the back side of the manual softener injection case 11e.
When putting powdered detergent, liquid detergent, bleach, or fabric softener into the manual charging case 11c, the user pulls out the manual charging case 11c, as shown in FIG. 6. Then, the user puts powdered detergent, liquid detergent, and bleach into the left detergent input manual case 11d. Further, the user puts the softener into the right-hand softener insertion manual case 11e. Thereafter, as shown in FIGS. 5 and 10, the manual input case 11c is pushed back into its original position. Therefore, when putting in detergent or softener, the manual loading case 11c can be pulled out, the detergent or softener can be put in, and the detergent or softener can be put away by pushing it to the back.

Further, as shown in FIG. 10, a detergent injection hole 17a for introducing powdered detergent, liquid detergent, and bleach is formed on the longitudinal extension of the vertically elongated detergent injection manual case 11d. Therefore, as shown by arrows α15 and α16 in FIG. 9, powdered detergent, liquid detergent, and bleach can be smoothly introduced into the detergent input hole 17a.
By arranging the detergent inlet hole 17a perpendicularly to the lattice part 11d2 having the cutout 11d1 of the detergent inlet of the manual detergent inlet case 11d, detergent falls into the detergent inlet hole 17a by the reaction when the manual inlet case 11c is pushed in. It becomes easier.

By making the hole (detergent injection hole 17a) of the path leading from the manual detergent injection case 11d to the outer tank 6 on the extension line of the lattice part 11d2 having the cutout 11d1 of the manual detergent injection case 11d, as shown in FIG. Powdered detergent, liquid detergent, and bleach fall directly from the detergent injection manual case 11d into the detergent injection hole 17a of the path hole.
As a result, detergent is less likely to remain undissolved in the manual detergent injection case 11d (see FIG. 10).

According to the above configuration, when adding detergent or fabric softener, the tanks (11a, 11b) and the manual injection case 11c, which is the manual injection port, are unified with the detergent on the left side and the fabric softener on the right side. Users are less likely to get lost.
By eliminating the need for the user to worry about where to put the detergent or fabric softener, it is possible to prevent a decrease in cleaning power due to incorrectly adding the detergent or fabric softener. It also reduces the hassle of cleaning due to adding detergent or fabric softener incorrectly.

As shown in FIG. 10, the detergent injection hole 17a of the path connecting to the cutout 11d1 of the lattice portion 11d2 of the pull-out manual detergent injection case 11d and the tank (water quality/temperature/detergent detection tank 6k and outer tank 6) is oriented vertically. It becomes.
Therefore, it becomes difficult for powdered detergent, liquid detergent, and bleach to remain undissolved in the pull-out manual detergent input case 11d.
AI washing (washing according to the water quality, temperature, type of detergent, and dirtiness of the clothes) works properly by flushing out powdered detergent, liquid detergent, and bleach without leaving any residue.
Furthermore, insufficient cleaning due to undissolved powder detergent, liquid detergent, and bleach remaining in the manual detergent input case 11d is eliminated. There is no need to clean the manual detergent injection case 11d due to undissolved powder detergent, liquid detergent, or undissolved bleach.

<Modified example>

On the other hand, in the modification shown in FIG. 14, the lattice portion 11d2 having the cutout 11d1 of the manual detergent injection case 11d and the detergent injection hole 27a are configured to at least partially overlap when viewed from above.

According to the modified example, by providing the detergent inlet hole 27a below the grid section 11d2 from which the powdered detergent, liquid detergent, and bleach flow down, the powdered detergent, liquid detergent, and bleach flow into the tank (water quality and temperature).・It becomes easy to fall into the detergent detection tank 6k or outer tank 6).

<<Other embodiments>>
1. In the embodiment described above, a case has been described in which the manual charging case 11c is located below the vertical line of the softener tank 11b when the manual charging case 11c is closed. 11c may be located.
