Description

[Detailed Description of the Invention] (1) Object of the Invention (1) This invention relates to a washing machine that efficiently removes dirt from laundry fabric without damaging it using vibrational energy of an audio frequency. It is something that drops.

Most of the household washing machines that are currently being reprinted remove dirt from the fibers by mechanically agitating the laundry in water, but the only control part is the agitation time, and the washing machine It is difficult to set detailed washing conditions according to the amount of items, the type of am, and the type of dirt. Also, since the laundry is rubbed vigorously in the washing tub, the fabric gets damaged quickly.

A-sound waves are also used for industrial cleaning, cleansing, and cleaning of jewelry, etc., but there are not many controllable factors in that case either.

To the I1G problem that the invention aims to solve, the present invention allows fine-grained washing conditions to be set according to the amount of laundry, the type of fiber, and the type of dirt, and also does not place a large burden on the fabric. The purpose is to provide a washing machine that can wash clothes.

Means for Solving the Constituent Problems of the Invention In the washing machine of the present invention, the bottom of the cylindrical water tank is formed into a cone shape, and a mechanism is provided to apply vibrations at an audio frequency to the cone-shaped bottom. It is characterized by

An example of such a structure will be explained with reference to FIG. 1. The bottom part 2 of a cylindrical water tank l in which laundry is placed is formed into a cone shape, and a mechanism 1 that applies vibrations at a dark voice frequency to the cone-shaped bottom part 2 is provided, for example, as shown in the figure. A coil 4 fixed to the lower end 3 of the cone-shaped bottom is inserted into a fixed magnet 5 as shown in FIG. The current carrying the sound is sent to the coil 4 through the external connection terminal 6.6' and the lead wire 7.7'.If the external connection terminal 6.6' is connected to the audio output terminal of a tape recorder, etc. Yes. Of course, a tape recorder or the like may be built in.

This structure, in which a coil fixed to the lower end of a cone is inserted into a fixed magnet and a current carrying sound is passed through the coil, is generally used as a speaker. That is, the present invention can be considered to have a speaker structure in the lower part of the washing TFA tank.

In order to facilitate JR movement of the cone-shaped bottom, it is desirable that the connecting portion 8 between the cylindrical part of the water tank and the cone-shaped bottom be formed in a bellows shape. Note that symbol 9 is a drain pipe.

Further, in order to increase the movement of water in the tank, an air blowing pipe 10 is provided at the bottom of the tank to blow air into the tank, thereby increasing the washing effect.

Function When the water tank of the washing machine of the present invention is filled with water, laundry is placed therein, and audio frequency vibrations are applied to the cone-shaped bottom, the water in the tank vibrates and removes dirt from the laundry.

The washing effect is further enhanced by blowing air into the water tank.

It is possible to remove stains efficiently by applying vibrations at an appropriate frequency and intensity depending on the amount and type of fibers, the type of dirt, etc., and changing them programmatically during washing. Detergents do not need to be used, but may be used depending on the target.

Setting and changing the frequency, intensity, etc. can be done using electrical signals, so control and programming are easy.

C1 Effects of the invention l) a) Since mechanical agitation is not involved, there is less damage to the laundry fabric.

2) Dirt can be removed efficiently by applying vibrations of optimal frequency and intensity depending on the amount and type of fibers, the type of dirt, etc.
