And water can be taken out from the water outlets 22 and 23 at the front ends of the flow paths 20 and 21 to be supplied to the inside of the dewatering tank 9, thereby being placed inside the dewatering tank 9. The laundry can be directly sprayed with water in a wide range, so that the wide range of laundry can be directly infiltrated with water, and the water can be quickly immersed in the laundry.

  In addition, the water receiving part 19, the flow paths 20 and 21, and the water outlet parts 22 and 23 are provided in the overhanging part 15a of the water tank cover 15 (the part covering the dehydration tank 9). The overhanging portion 15a originally exists for the formation of the water supply pipe connection port 16 and the like, and it is an opening inside the water tank cover like a conventional water channel added to the entire inner periphery of the water tank cover 15. There is no narrowing. Therefore, it is possible to avoid the difficulty of taking in and out the laundry.

  In addition, in the above configuration, water is supplied to the water receiving portion 19 from the water supply valve 38 through the water supply case 39 through the water supply case 39, and a gap 42 is provided between the water supply pipe 40 and the water receiving portion 19. It is separated and opened to the atmosphere. As a result, when the shower case 18 is clogged with water, overflow can be performed from the separation portion (gap 42) between the water supply pipe 40 and the shower case 18, and the water supply case 39 on the upstream side thereof. Thus, it is possible to prevent overflow from occurring in the rear box portion 37.

  Moreover, in the thing of the said structure, the water receiving part 19 shall make the inclination shape which descends toward the flow paths 20 and 21. As shown in FIG. Thereby, water can be smoothly flowed from the water receiving part 19 to the flow paths 20 and 21.

  Furthermore, inclined surfaces 25 and 26 that gradually descend in the extending directions of the flow paths 20 and 21 are provided in the water dividing portions of the flow paths 20 and 21 extending in a plurality of different directions. This also allows water to flow smoothly through the channels 20 and 21. In addition, about these inclined surfaces 25 and 26, they are formed by the protruding part 24 which forms a taper shape in the opposite direction to the water receiving part 19 side, and thereby each outer periphery of the flow paths 20 and 21 is formed. Since the side (rear side) has a long inclined surface and the water flowing toward the flow paths 20 and 21 can be more vigorous toward the outer peripheral side, the speed of the water flowing on the outer peripheral side is increased, and water is applied to a wider range of laundry. Can be permeated directly.

  The plurality of flow paths 20 and 21 have different lengths. Thereby, it is possible to apply water asymmetrically to the laundry in the dewatering tub 9, and the water immersion of the laundry can be asymmetrical. In addition, it is possible to arrange the flow paths 20 and 21 without difficulty while maintaining the relative position with other parts such as the air supply pipe connection port 17 or other parts.

Moreover, the water outlet parts 22 and 23 are each formed with a plurality of water outlets 22a to 22d and 23a to 23d. Thereby, water can be directly infiltrated into most of the laundry in the dewatering tub 9, and the water can be further immersed in the laundry.
The water outlets 22 and 23 have a plurality of water outlets 22a to 22d and 23a to 23d separated from each other. As a result, water discharged from the respective outlets 22a to 22d and 23a to 23d can be dispersed and discharged without sticking at the destination, so that water can be more reliably directly supplied to most of the laundry in the dewatering tank 9. It can be infiltrated and can further accelerate the soaking of the laundry.

Furthermore, the water outlets 22 and 23 have a plurality of water outlets 22a to 22d and 23a to 23d radially. This also allows water from each of the plurality of water outlets 22a to 22d and 23a to 23d to be released at a wide angle without sticking to the destination, and more reliably directly penetrates most of the laundry in the dewatering tank 9. This can further accelerate the water soaking of the laundry.
Moreover, the water outlets 22 and 23 have a plurality of water outlets 22a to 22d and 23a to 23d oriented in the horizontal direction. Thereby, each of the plurality of water outlets can fly the water from 22a to 22d and 23a to 23d farther, and the water in the dehydrating tub 9 can be directly permeated more reliably. This can further accelerate the water soaking of the laundry.

  The flow paths 20 and 21 include main flow paths 20a and 21a extending from the water receiving section 19 and a plurality of distribution flow paths 20b to 20e connected to the plurality of water discharge openings 22a to 22d and 23a to 23d of the water discharge openings 22 and 23. , 21b to 21e, and steps 29, 30 are provided to make the distribution channels 20d, 20e, 21d, 21e on the inner side higher than the distribution channels 20b, 20c, 21b, 21c on the outer side. As a result, the speed of water exiting from the outer distribution channels 20b, 20c, 21b, and 21c is higher than the speed of water exiting from the inner distribution channels 20d, 20e, 21d, and 21e. Water can be directly permeated more reliably into many of the laundry items, and the water can be further submerged.

  Furthermore, the flow paths 20 and 21 make the front ends of the distribution flow paths 20b to 20e and 21b to 21e narrower than the opposite ends. Thereby, the speed of the water discharged from the water outlets 22a to 22d and 23a to 23d can be increased, and water can be directly permeated more reliably into most of the laundry in the dewatering tub 9. Can be soaked in water.

In contrast to this, FIG. 9 shows a second embodiment (second embodiment) of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only the part is described.
In this case, the cross-sectional areas of the channels 20 and 21 are gradually increased from the innermost distribution channels 20e and 21e to the outermost distribution channels 20b and 21b.
