Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a cylindrical hollow body made of a porous material in the dehydration tank so as to be located at the central axis of rotation of the dehydration tank, and the centrifugation caused by the rotation of the dehydration tank. This invention relates to a dehydrating and rinsing device that uses force to eject water from the peripheral wall of a cylindrical hollow body to rinse laundry.

Structure of the conventional example and its problems In the conventional dehydration rinsing device of this type, since the degree of opening of the peripheral wall of the cylindrical hollow body is constant, water is injected from a part of the cylindrical hollow body. In this structure, due to the influence of water pressure, more water passes through the porous part of the lower peripheral wall and is discharged, and the closer to the upper peripheral wall, the less water is discharged, and the laundry located in the upper part of the dehydration tank is This has the disadvantage that it is difficult to rinse compared to the laundry located in the lower part, which causes so-called uneven rinsing.

1 and 2 show a conventional device of this type,
1 is a box-shaped main body with a plurality of moving vehicles 2 on the outer bottom surface;
Reference numeral 3 denotes a washing tub disposed within the main body 1, and a dewatering tray 4 is integrally molded therein, and the washing tub 3 and the dehydrating tray 4 are arranged side by side. 5
is a stirring blade fitted in a concave portion of the inner bottom of the washing tub 3, which is intermittently rotated in forward and reverse directions via a pulley 7 and a belt 8 by a washing motor 6 fixed to the lower part of the main body 1.

Reference numeral 9 denotes a bottomed cylindrical dehydration tank rotatably arranged within the dehydration receiver 4, and has a large number of drainage holes 10 bored in its circumferential surface. A support spring 11 elastically supports the dewatering motor 12 which transmits rotation to the dehydrating tank 9 via a coupling mechanism. To explain the coupling mechanism in more detail, 13 is a rotating shaft of the dehydrating motor 12, and 14 is an end of the rotating shaft 13 connected to the dehydrating tank 9.
A vibration damping material made of a flexible material such as rubber, which provides a liquid-tight seal between the 15-piece rotating shaft 13 and the bottom of the dehydration receiver 4.

16 is a cylindrical hollow body with a bottom provided in the dehydration tank 9 so as to be located at the rotation center axis -1 of the dehydration tank 9, and its lower end is attached to and detached from one end of the rotation shaft 13 at the bottom of the dehydration tank 9 It can be combined freely. Although a description of this connection structure will be omitted, various types such as screw connection, fitting, etc. can be considered. The cylindrical hollow body 16 is made of, for example, porous sintered resin, and the degree of opening of the peripheral wall is constant. Reference numeral 17 denotes a water inlet provided near the negative opening end of the dehydration tank 9, through which water is poured into the cylindrical hollow body 16 from the opening in the negative direction. 1 standard water, 19 loads of laundry.

According to configuration 111, water 18 is released from the opening in the peripheral wall of the cylindrical hollow body 16 by the rotation of the dehydration tank 9.
), water is supplied to the laundry 19 and a dehydration effect is imparted to the laundry 19. This results in dehydration and rinsing.

However, since the opening degree of the peripheral wall of the cylindrical hollow body 16 is constant, the cylindrical hollow body 16 is
Because the water pressure in the lower part of the cylindrical hollow body 16 is high, a large amount of water is spouted into the dewatering tank e from the peripheral wall of the cylindrical hollow body 16 corresponding to the lower part. . Therefore, the water level inside the cylindrical hollow body 16 is
It does not reach near the upper end of 6. If dehydration and rinsing were performed in this state, almost no water would be supplied to the laundry 19 located in the upper part of the dehydration tank 9, and as a result, uneven rinsing would occur in the lower part of the laundry 19. .

OBJECTS OF THE INVENTION The present invention aims to solve the above-mentioned conventional drawbacks and eliminate uneven rinsing in the lower part of the laundry put into the dehydration tank.

``Configuration of the Invention'' - In order to achieve the purpose described above, the dehydration and rinsing device of the present invention has the following features:
A rotatable dehydration tank, a cylindrical hollow body made of a porous material located at the rotation center axis -1- of the dehydration tank and fixed in the dehydration tank, and a water inlet for injecting water into the cylindrical hollow body. Prepare,
The cylindrical hollow body has a peripheral wall having a constant wall thickness and a pore size that gradually decreases from the first end toward the lower end.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the third embodiment. In addition, in FIG. 3, the same reference numerals as in FIG. 2 indicate the same members, and the explanation thereof will be omitted. Reference numeral 16' denotes a cylindrical hollow body, which is integrally molded of, for example, a porous sintered 8 resin material, and the degree of aperture of its peripheral wall gradually decreases from the - end to the lower end.

-1- According to the structure, the pore size of the cylindrical hollow body 16' gradually decreases from the first end to the lower end. Outflow resistance increases, and therefore, water that has entered the cylindrical hollow body 16' becomes more difficult to exit into the dehydration tank 9 as it moves toward the lower end.

Because of this, in balance with the fact that the water pressure increases toward the bottom inside the cylindrical hollow body 16', an approximately equal amount of water is ejected from the entire circumferential wall, and therefore, the water pressure increases as it goes downward. The water level inside the cylindrical hollow body 16' reaches the vicinity of the upper end of the cylindrical hollow body 16', and during dehydration and rinsing, centrifugal force causes water to gush out from the entire circumferential wall of the cylindrical hollow body 16' as shown in a, and the washing process is completed. The entire object 19 is rinsed uniformly and thoroughly without any separation between the upper and lower parts.

Effects of the Invention According to the present invention, the whole laundry can be uniformly and sufficiently removed from the lower part by changing the degree of opening of the peripheral wall of the cylindrical hollow body. It can be rinsed with water, and its industrial value is extremely large.
