The invention relates to consumer goods and can be used in consumer services, medicine and other purposes.
The essence of the device for washing lies in the fact that , in addition to the main piezoelectric element, piezoelectric elements are additionally built in, capable of generating ultrasonic (ultrasonic) and electromagnetic microwave (microwave) oscillations under the influence of an electric voltage, so that ultrasonic vibrations create a torque in the liquid during operation of the device, And microwave and ultrasonic vibrations act on the liquid synchronously and in phase from one source. This design of the device for washing expands its technological capabilities.
DESCRIPTION OF THE INVENTION
The invention relates to consumer goods and can be used to wash clothes, disinfect water for medicinal purposes, etc.
A laundry device is known which is a piezoelectric disc coated with plastic and placed in a washing tub ( RU 2047676 C1, 10.11.95 ). Washing with this device is due to ultrasonic waves, which are generated by a piezoelectric device inside the tank. When the device is in operation, a large number of vacuum bubbles are formed which penetrate the fibers of the tissue and, collapsing, knock out foreign inclusions without damaging the tissue fibers mechanically.
The disadvantage of this device is low technological capabilities due to low efficiency when washing dense fabrics and the absence of bactericidal properties, that is, the ability to destroy pathogenic bacteria and fungi during work.
A washing device is also known , comprising a reservoir and a vibrating element of the ultrasonic frequency placed therein, creating a torque ( US 2468550 A, April 26, 1949 ).
A disadvantage of the known device is the low efficiency of processing the laundry.
The technical result achieved in the implementation of the invention is to expand the technological capabilities of the device for washing.
The above technical result is achieved by the fact that in a washing device comprising a container and a vibrating element of the ultrasonic frequency generating a torque applied therein, in accordance with the invention, multifunctional piezoelements are additionally arranged in the tank in such a way that electromagnetic microwave oscillations irradiate most of the working volume and are generated by one Source of ultrasonic and microwave oscillations.

The device comprises a vibration element body 1, a vibration piezoelectric element 2, additional piezoelectric elements 3 and a sealed coating 4. Conditionally, contacts 5 are shown for supply voltage. The piezoelectric elements 3 show the radiating surface 6 and the screen 7; The tank, on the bottom of which the device is placed for washing, is not shown conditionally.
The device works as follows. For washing, the device is placed in a container with a liquid in which the detergent is dissolved, then laundry is placed in the tank. After the power supply is switched on, the voltage is applied simultaneously to the main vibrating piezoelectric element 2 and additional piezoelectric elements 3. The vibrational piezoelectric element 2 starts to generate ultrasonic vibrations propagating throughout the volume of the liquid, due to which the washing process occurs. The additional piezoelectric elements 3 generate synchronous and in-phase electromagnetic microwave and ultrasonic vibrations, which, due to the location of the piezoelectric elements 3 along the perimeter of the device, will create additional turbulence in the fluid, which promotes better mixing of the liquid and laundry.
New in this device is the creation of synchronous and in-phase effects on the liquid of electromagnetic microwave and ultrasonic vibrations. The creation of torque in the liquid can reduce the washing time, and the synchronous action of microwave and ultrasonic vibrations increases the efficiency of the destruction of bacteria and fungi. The additional radiating piezoelectric elements 3 are made according to the Gunn diode scheme, while the screens 7 for microwave and ultrasonic vibrations are mounted on one side and arranged so that during the operation of the device the maximum torque in the liquid is created. The radiating surfaces 6 of these piezoelements are located at some angle to the plane of the main vibrational piezoelectric element 2 for the propagation of microwave and ultrasonic vibrations throughout the volume of the liquid. The use of additional piezoelements in the device, which are made of a semiconductor material capable of synchronous and in-phase generation of microwave and ultrasonic vibrations, dramatically expanded its technological capabilities. Technological possibilities have expanded further due to the fact that the frequency of oscillations generated by additional piezoelements is two orders of magnitude or more higher than that of the main piezoelectric element, which allowed to erase fabrics of any density and with a high pollution factor. The device can be used in medicine for sterilization of various materials in liquid media, in a household for the destruction of bacteria on the surface of food products (for example, vegetables, fruits) and so on.
CLAIM
A washing device comprising a tank and a vibrating ultrasound element placed therein, which generates a torque, characterized in that the multifunctional piezoelements are additionally arranged in the reservoir such that electromagnetic microwave oscillations irradiate most of the working volume and are generated by a single source of ultrasonic and microwave oscillations.
