Description

[Detailed description of the invention] The present invention provides a device whose purpose is to cause air to flow into the liquid in the washing tub during washing to generate a foaming action.As shown in the drawing, the bottom plate 1 A bearing cylinder 3 hanging down from the center of the top of the inner surface of a rotating body 2 in the form of a cover plate covered with a lid is passed through the bottom plate 1, and the bearing cylinder 3 is placed on top of a connecting pipe 5 fixed to the bottom of the washing tub 4. The rotating shaft 6 of the motor is inserted into the bearing sleeve 3 from below the connecting pipe 5, and the upper part is connected to the rotating body 2 with a screw 7, and the inner diameter of the lower part of the bearing sleeve 3 is made larger than the outer diameter of the rotating shaft 6. A radial horizontal hole 9 communicating with the cavity 8 is bored, and several vertical holes 10 communicating with the cavity 8 are bored in the connecting pipe 5.
A bowl-shaped body 12 having circular holes 11 on the top surface is fitted into several places around the circumference of the rotating body 2, and the shaft rod 14 of the sphere 13 that is in contact with the outer surface of the circular hole 11 of the bowl-shaped body 12 is attached to the support plate 15. The spiral 17 is wound around the shaft rod 14 between the stop plate 16 and the support plate 15 at the inner end of the shaft rod 14.

With the above-described configuration of the foaming device of the present invention, external air is passed through the vertical holes 10 of the connecting pipe 5, from the cavity 8 in the lower part of the bearing sleeve 3, through the radial horizontal holes 9 to the rotating body, as shown by the arrows. It will flow inside.

When doing laundry, when the rotating body 2 is rotated by the rotation shaft 6 of the motor, each of the spheres 13 attached to the bowl-shaped body 12 on the periphery of the rotating body 2 spirals due to centrifugal force, as already shown in Figure 8. 17 and is ejected outward, and the sphere 1
The circular hole 11 of the bowl-shaped body 12, which was closed by 3, is opened.

Therefore, as the internal pressure of the rotating body 2 decreases, outside air is allowed to flow into the washing tub 4 through the circular hole 11 as shown by the arrow.
Since air is ejected into the water while the rotating body 2 rotates, air bubbles are generated in the washing liquid.

The generation of air bubbles in the washing liquid accelerates the cleaning action, shortens washing time, and oxidizes the air flowing into the washing liquid, reducing the amount of detergent used. It is economical and helps prevent pollution caused by detergents.

When the washing is finished and the rotation of the rotating body 2 by the rotary shaft 6 of the motor is stopped, the spheres 13, which had been ejected outward due to the centrifugal force, are moved inward by the elongation of the spiral 17, as shown in FIG. 8a. The round hole 11 of the bowl-shaped body 12 is closed by the sphere 13, and the flow of air into the washing tub 4 is stopped.

As described above, the foaming device of the present invention has practical effects such as improving the cleaning effect of electric washing machines, saving detergent, and preventing detergent pollution, and is a very useful utility model in practice.
