DETAILED DESCRIPTION OF THE INVENTION The present invention provides a washing and dehydration tank having rotary blades at the center of the bottom, and a net-like container that is open at the top and placed inside the dehydration tank, and that can be freely rotated. support,
Regarding dehydrating washing machines that wash items such as blankets that are likely to be damaged if they come in direct contact with the rotary blades,
The purpose is to improve the cleaning effect.

This will be explained below based on the drawings. Reference numeral 1 denotes an outer tank, and a washing and dehydrating tank 2 made of synthetic resin is housed inside. An opening 3 is provided in the center of the bottom of the dehydration tank 2. A rotor blade 5 attached to a rotor shaft 4 is disposed within the opening 3, and a plurality of back blades 6 are provided on the back surface of the rotor blade 5. It is formed. A large number of dehydration holes 7 are provided in the side wall of the dehydration tank 2, and reinforcing vertical ribs 8 and horizontal ribs 9 are provided on the outside thereof.

Concentric ribs 10 for reinforcement are provided on the outer bottom of the dehydration tank 2.
and a radial rib 11 are integrally suspended, and a boss 12 is integrally formed on the third rib from the inside among the concentric ribs, and a boss 12 is integrally formed on the third rib from the inside among the concentric ribs.
is not completely circular, and a part of it is 13
is open. Reference numeral 14 denotes a dehydration tank board fixed to the dehydration tank drive shaft 15. The innermost rib 10' and the boss 12 are in contact with the board 14, and the screw 18 is tightened to the boss 12 to connect the board 14 and the dehydration tank. It is connected to water tank 2. And the substrate 14 and the rib 1
0' forms a pump chamber 19. Board 1
4 is provided with a plurality of through holes 20, and when the rotor blade 5 rotates, the outer tank 1 and the dehydration tank 2 are separated by the pumping action of the back blade 6.
The liquid between them (which eventually becomes the liquid in the dehydration tank 2) is sucked into the pump chamber 19 through the through hole 20.

21 is a bearing case, and 22 is a motor, which are attached to the bottom of the outer tank 1 suspended from a machine frame (not shown). A vertical groove 23 is formed in the side wall of the dehydration tank, and the lower end of the vertical groove 23 is open.
This lower end opening communicates with a discharge waterway 24 of the pump chamber 19 formed on the outer bottom surface of the dehydration tank.
This discharge waterway 24 is connected to the opening 1 of the rib 10'.
3, the horizontal part 25 is integrally molded with the dehydration tank 2, and the corner part 27 is formed by a water channel cover attached to the outer periphery of the outer bottom surface.

A water pipe 28 is fitted into the vertical groove 23 .

That is, the lower end of the water pipe 28 communicates with the discharge waterway 24, while the upper end is inserted into a holding part 30 formed at a suitable position of the balance ring 29, and is pressed downward by a cover 31 attached to the upper surface of the balance ring. The water pipe 28 is designed not to come out of the discharge waterway 24.

The cover 31 also functions as a guide for redirecting the liquid discharged upward from the upper end of the water pipe 28 downward. That is, the liquid sucked into the pump chamber 19 as shown by the arrow in FIG.
The water is discharged from above the dehydration tank into the dehydration tank through a water supply channel constituted by 8, a cover 31, and the like.

An annular rail 32 along the mouth edge of the dehydration tank 2 is attached to the outer bottom surface of the balance ring 29 with screws 33, and a rotary ring 34 is rotatably supported on this rail 32. That is, the rotating ring 34
includes a plurality of rollers 3 sliding on a rail 32.
5 is pivotally supported by a shaft 36. Reference numeral 37 denotes a net-like container having approximately the same size as the dehydration tank disposed in the dehydration tank 2, and a locking hole 39 formed in a lip frame 38 made of a soft resin that shapes the mouth of the container projects into the rotating ring 34. The container 37 is connected to the rotary ring 34 by hooking the hook 40 and is rotatable. The sides of the container 37 are made of easily deformable nets 41, and the bottom of the container 37 is made of a wear-resistant, easily deformable base 42 without large holes. and container 37
When the base 42 is placed in the dehydration tank, the rotor blade 5
Its dimensions are regulated so that it touches the top.

The center of rotation of this container 37, that is, the center O of the rotating ring 34, is shifted from the center of rotation O' of the rotary blade 5 by a distance A to the opposite side of the water pipe 28.

In such a structure, when washing a large item such as a blanket M that is easily damaged, place the mesh container 37 in the dehydration tank 2 as shown in FIG. Supply water up to water level H.

When the rotary blade 5 is rotated, a swirling water flow is generated, and this water flow penetrates into the blanket M. Also, the liquid between the outer tank 1 and the dehydration tank 2, which is sucked into the pump chamber 19 by the pumping action of the back blade 6 of the rotary blade 5, is discharged from the upper end into the container 37 through the water pipe 28, and the blanket M Penetrates into the blanket from the top. Therefore, the blanket M is washed by the water flow or swirling water flow penetrating from the upper part.

The swirling water flow also causes the container 37 to rotate in that direction. Particularly in this case, since the base 42 of the container 37 is in contact with the rotor 5, the base 42 is in contact with the rotor 5.
The rotation of the container 37 is promoted as it tries to be rotated together with the container 37. Therefore, by rotating this container 37, the blanket M
It also rotates and constantly changes its position, so
The swirling water flow or the water flow discharged from the upper end of the water pipe 28 penetrates into the blanket evenly, so that washing can be carried out with less uneven washing. Further, the centrifugal force caused by the rotation of the container 37 has the effect of forcing the liquid discharged from the upper end of the water pipe to the outside through the blanket.

During such washing, since the blanket M is prevented from touching the rotary blades 5 by the container 37, the cloth will not be damaged.

Incidentally, the container 37 rotates regularly if its center of rotation is on the center of rotation O' of the O rotor 5, but in the present invention, the center of rotation O of the container 37 is aligned with the center of rotation of the rotor. Since it is deviated from O' by the dimension A, the container 37, especially the lower part, rotates while swinging from side to side, giving the blanket M complex movements. Therefore, the cleaning effect is improved compared to a case where the rotation center of the container and the rotary blade are the same.

In addition, in the case where the water supply pipe 28 is disposed inside the dehydration tank 2 to form a water supply channel, the water supply pipe 28 protrudes into the dehydration tank, so that the rotation center O of the container 37 is aligned with the rotation center of the rotor blades as in the present invention. If it is shifted from the center O' to the side opposite to the water pipe 28, the volume inside the dehydration tank 2 can be effectively utilized, the diameter of the container 37 can be increased, and a large blanket can be washed. Furthermore, in general, when the water pipe 28 is disposed inside the dehydration tank 2, the dehydration tank is heavier with the water pipe 28 in the center of the tank, but by shifting the container 37 to the side opposite the water pipe, the dehydration tank becomes heavier. 2 balance can be corrected, and the occurrence of abnormal vibrations during dehydration can be reduced.

If the container 37 is taken out from the dehydration tank 2, normal washing can be carried out in the dehydration tank.

As described above, according to the present invention, the rim of the washing/dehydration tank having the rotary blade at the center of the bottom is open at the top, and the rim of the net-like container disposed inside the dehydration tank can be freely rotated. This container is used to wash items such as blankets, which are easily damaged if they touch the rotating blades directly, and the center of rotation of the container is shifted from the center of rotation of the rotating blades, making the rotation of the container complicated. The cleaning effect can be improved by giving movement to the blanket, etc. inside.

In addition, if the dehydration tank is equipped with a water supply channel that sucks up the liquid in the dehydration tank by the pumping action of the back blade of the rotor, the center of rotation of the container can be shifted to the opposite side of the water supply channel, allowing the container to become larger. It can also be used to improve the balance of the dehydration tank.
