Description

 The invention relates to a method and apparatus for washing clothes.

 A known method of washing clothes, which consists in placing the emitter in a solution of washing liquid, followed by the formation of the energy of the emitter and converting the latter into the movement of the washing liquid to affect the pollution of the linen. There is also known a device for washing clothes containing a power source and an emitter connected to it, placed in a washing liquid, including a piezoelectric element located in a housing filled with a dielectric filler (RF patent N 2O476766, DO6F 7/04, 1995 - analogue and prototype).

 A disadvantage of the known method and device for washing clothes is the low quality of washing clothes.

 In the method, this result is achieved by the fact that before generating the energy of the emitter, an electric sinusoidal signal is generated with a frequency of 1 to 100 kHz, modulated by a frequency of 10 to 500 Hz with a voltage of up to 300 V, and the energy of the emitter is converted into the movement of the washing liquid by excitation in the washing liquid sinusoidal acoustic wave with a nonplanar front.

 In the device, this result is achieved by the fact that the piezoelectric elements are mounted on metal plates, on the back of which acoustic wave resonators are placed, and the power source is made in the form of a transducer with the possibility of generating an electric modulated sinusoidal signal and connected to the piezoelectric elements, the case being made of soundproof material.

 The device has weights installed in a housing made of polyethylene.

 In FIG. 1 shows a block diagram of a device; in FIG. 2 - section of the emitter; in FIG. 3 - section of a metal plate with a piezoelectric element and a resonator of acoustic vibrations.

 The device for washing clothes contains a transducer 1, the input of which is configured to be connected to an electric network, an emitter 2, including metal plates with acoustic piezoelectric elements 5 and acoustic resonators 6 installed on them on one side and filled in with a dielectric filler 4; fluctuations. the Converter 1 is configured to generate an electric modulated sinusoidal signal.

 In the housing 3, made of a soundproof material, for example, polyethylene, weights 8 are placed, providing the immersion of the emitter 2 in a solution of a washing liquid. The resonators 6 are made, in particular, of plastic and can have various shapes, for example spherical.

 The dielectric filler 4 provides sealing of the emitter 2 and fixing all the internal elements of its structure.

 The operation of the method and device for washing clothes is as follows.

 Washing is done in a basin, bucket, tank or bath. Moreover, the washing solution should only cover the surface of the laundry freely floating in it.

 Hot water is poured into the container, washing powder is poured, which is mixed to form a solution of a washing liquid. At the bottom of the tank place the emitter 2. Then, the laundry is immersed in the tank. Converter 1 is connected to an electrical network (220 V, 50 Hz).

 Converter 1 generates an electrical signal with a frequency in the range from 1 to 100 kHz, modulated by a frequency from 10 to 500 Hz with a voltage of up to 300 V.

 The generated signal through the cable 9, wires 11 and through the contacts 10 is fed to the piezoelectric elements 5. The latter are excited and emit acoustic waves, the shape of which coincides with the generated sinusoidal signal. Acoustic waves are amplified by resonators 6, forming a nonplanar wave front, and washing liquid is transmitted through the wall of the housing 3, in which elastic waves arise that cause its movement (micromotion) relative to the erased fabric, thereby achieving an intensification of the effect of the washing liquid solution on fabric pollution.

 At the end of the wash, the transducer 1 is disconnected from the network, the emitter 2 is removed from the solution of the washing liquid, washed and wiped dry.

 The proposed method and device for washing clothes increase the quality of washing clothes due to the more intense and full effect of the washing solution on the soiling of the laundry.

 The invention meets the criterion of "industrial applicability", as it is made from known and common parts and materials, and can be used when washing any types of linen.
