Description

[Detailed description of the invention] <Industrial application field> This invention relates to a new type of washing machine that does not use detergent.

<Conventional technology and problems> Conventional washing machines add detergent and laundry to cold or hot water,
Stirring methods are often used, but rinsing after washing requires a lot of water and time, and detergents can cause laundry to deteriorate.
There are disadvantages such as deformation, discoloration, twisting, and wrinkles, as well as the need for a large motor for stirring.

Means for Solving the Problems> In order to solve the above problems, the present invention applies ultrasonic vibrations to the laundry stored together with water in a washing tub, and aerates ozone bubbles to achieve a synergistic effect between the two. It is an object of the present invention to provide a washing machine that can efficiently wash clothes without using detergent or vigorous stirring.

Effect> There is no air in the laundry soaked in water in the washing tub. Therefore, the ultrasonic waves transmitted into the washing tub act on the laundry using water as a medium, and 90% of the energy is absorbed by the laundry, while the ultrasonic waves that do not hit the laundry reach the opposing inner wall of the tub and are reflected. .

Ultrasonic cavitation is essentially a vacuum bubble, and when it disappears, an impulsive pulse wave is generated, which uses its sound pressure and acceleration to stir up the surrounding water and remove dirt from the fabric surface.

This is the actual state of washing action using ultrasonic waves.

In addition, ozone, which is sprayed in the form of bubbles into water, has the property of dissolving in water, so it accelerates the oxidation of laundry, bleaching, sterilizing, and deodorizing it. Effective washing is achieved without the use of.

<Example> As shown in the attached drawings FIGS. 1 to 3, an appropriate number of ultrasonic oscillators 2 and a required number of bubble blowing nozzles 3 are appropriately arranged on the peripheral wall and bottom of the washing tub 1, Each ultrasonic oscillator 2 is driven by the output of an ultrasonic oscillator 4 whose frequency can be freely adjusted within the range of 10 KIIz to I MHz, and the air/foam blowing nozzle 3 is a static mixer and has a large number of fine holes. It consists of a sprayer, a nozzle with a porous material attached to the mouth, and can eject air bubbles of 50 microns or less.
It is preferable that the bubble particles can be adjusted.

Each of the bubble blowing nozzles 3 described above may be connected to an ozone generator 5 to blow ozone directly into the washing tub 1, but in this embodiment, the drain port 6 provided on the bottom of the washing tub 1 is connected to a drain pipe 9.
Then, the water in the washing tub 1 is connected to the air bubble blowing nozzle 3 together with the ozone generator 5 via the circulation pump 10 and the check valve 11 via the electromagnetic switching valve 8 that switches to the suction port of the circulation pump 10, and the water in the washing tub 1 is pumped through the pump 10. An aeration method is adopted in which the ozone from the ozone generator 5 is sucked by the injector action of the circulating water, the ozone is blown into the tank together with the circulating water, and the circulation of this water creates an agitation action in the washing tub 1. However, it is designed to create a gentle agitation effect in the tub so that the original washing process using ultrasonic waves and ozone aeration acts evenly on the laundry.

At the bottom of the washing tub 1, a water passage hole 7 is provided at the lower end, a tangle prevention pipe 14 is established, and a partition plate 1 is provided above the water passage hole 7.
An ultrasonic oscillator 2 and a bubble blowing nozzle 3 are also provided in the upper hollow portion of the cell.

Washing M tank 1 further supports laundry and collects settled dirt and m
A porous support plate 17 made of a net-like or perforated plate through which fiber debris and the like can pass is provided with a slight distance from the bottom surface, and an overflow prevention plate 18 made of a removable net-like or perforated plate is provided on the entanglement prevention pipe 14. , the whole is housed in an exterior case 19.

In addition, in the figure, 20 is a water tap, 21 is an overflow pipe, and 22
is a level sensor, and 23 is the lid of the outer case.

The washing tub 1 mentioned above can be made of metal or synthetic resin, but one made of special fine ceramic is most suitable in terms of strength because it vibrates accurately at the set electrosonic frequency and has a good ultrasonic wave reflection effect. It is.

In the above configuration, after removing the overflow prevention plate 18 in the washing tub 1 and storing the laundry on the porous support plate 17, the overflow prevention plate 18 is fitted to the tangle prevention pipe 14, so that the upper surface of the stored laundry is Water is poured to the extent that it is below the water surface, and the ultrasonic oscillator 2 is activated by the output of the ultrasonic oscillator 4.

The frequency of the ultrasonic waves varies depending on the material, structure, etc. of the laundry, but increases with the ranking of human silk, cotton, linen, silk, wool, synthetic IJf fiber, etc., and is determined in the range of 10 KHz to 1 MHz.

At the same time, washing is performed by blowing the ozone generated by the ozone generator 5 into the tank from the bubble blowing nozzle 3 in the form of bubbles of 50 microns, and the lightly soiled items separated from the laundry float to the surface of the water. Heavy objects pass through the porous support plate 17 and settle to the bottom of the tank. The time required for washing varies depending on the amount of laundry, type and degree of dirt, but it is 5 to 1
The process is completed in 5 minutes, and the dirt that has risen to the surface of the water is discharged from the overflow pipe 21 by pouring water at the end of washing, and is also discharged by the above operation during washing.

This operation can be carried out manually or by using a vj device that injects water at fixed intervals using a timer.
The waste fibers and the like that have settled on the bottom of the tank are caused to flow out from the drain pipe 9 by switching the drain port 6 to the drain pipe 9 using the electromagnetic switching valve 8 together with the water in the tank.

At this time, since the laundry is supported by the porous support plate 17 and there is a gap on the lower surface, there is no fear that settled dirt or fiber debris will adhere to the laundry.

FIG. 4 shows another embodiment, in which:
This is a horizontal washing tub without an entanglement prevention vibrator 14, a porous support plate 17, and an overflow prevention plate 18. The laundry is stored in a perforated plate or net-shaped middle drum 33, and the drum support shaft 34 is set as in the embodiment described above. Washing tub 31 with the same configuration as the washing tub of
The drum 33 is supported by a shaft support groove 32 provided in the drum 33 so that the laundry can be stored or taken out. In the figure, the drum 33 is divided into two in the direction of the spindle, and the -
Although the drum is shown with two sides connected to each other so as to be openable and closable with a hinge 35 and an appropriate fixing fitting 36 attached to the other side, any other configuration may be adopted, such as providing a window hole in the peripheral wall of the drum that can be opened and closed.

Further, if the drum 33 is provided with a drive mechanism 37 that rotates the laundry slowly as needed, and the laundry is rotated, the washing effect of the combination of ultrasonic waves and ozone can be uniformly applied to the entire laundry, thereby shortening the washing time.

Other than the above, this embodiment is the same as the embodiment described above.

<Effects of the Invention> In this invention, the synergistic effect of the combination of rice sound waves and ozone aeration allows for efficient washing, and since detergent is used, there is no deterioration, discoloration, shrinkage, etc. of the laundry caused by the detergent. In addition to the bleaching, sterilization, and deodorizing effects of ozone, it also reduces the number of steps required for rinsing and the amount of water used, and the laundry does not need to be rotated vigorously (1), so there is no damage, loss of shape, or twisting, and there is no need for stirring. There are excellent effects such as no need for a large motor for the purpose of the motor, and the overall size can be reduced.
