Description

A washing machine with an ultrasonic device

technical field

The invention relates to the technical field of washing machines, in particular to a washing machine equipped with an ultrasonic device.

Background technique

Ultrasound has a cleaning function. The principle is that the ultrasonic generating device includes an ultrasonic generator and an energy converter. The high-frequency oscillation signal sent by the ultrasonic generator is converted into a high-frequency mechanical oscillation by the energy converter and propagated to the medium. The ultrasonic wave in the cleaning solvent is The forward radiation in the cleaning liquid makes the liquid flow and generate tens of thousands of tiny bubbles. The tiny bubbles in the liquid vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles grow rapidly. Then it closes suddenly, and shock waves are generated when the bubbles close, and thousands of atmospheric pressures are generated around them, destroying insoluble dirt and making them disperse in the cleaning solution. When the group particles are wrapped in oil and adhere to the surface of the cleaning parts, The oil is emulsified, and the solid particles are separated, so as to achieve the purpose of cleaning the surface of the cleaning parts.

Due to the characteristics of ultrasonic waves, people have been trying to apply ultrasonic cleaning technology to traditional washing machines to make up for the insufficiency of washing machines in dealing with stubborn stains on certain parts. There are many patents related to this, and even some washing machine manufacturers are in the market. Launched an ultrasonic washing machine.

However, because cloth or cotton items have the effect of absorbing ultrasonic waves, ultrasonic washing machines have a large loss of ultrasonic waves when washing fabrics; in addition, the cleaning principle of ultrasonic washing machines is to vibrate and clean through high-frequency ultrasonic cleaning equipment emitted by ultrasonic transducers. The liquid in the tank produces many small high-frequency bubbles. These small bubbles continuously hit the surface of the fabric to be cleaned, and resonate with the stains and oil stains on the surface of the fabric to be cleaned, so that the stains and oil stains fall off! For fabrics such as clothing, the stains of cotton products are adsorbed inside, or have penetrated into its molecular or atomic organization. High-frequency air bubbles can only resonate on the surface of the clothing. \ Cotton clothes are not ideal.

In view of this, the present invention is proposed.

The ultrasonic generating device is provided in the washing machine mainly to use the following characteristics of ultrasonic waves to deal with stubborn stains or stains that are not easy to handle in ordinary washing machines.

Mechanical effect: The mechanical effect of ultrasound can promote the emulsification of liquids, the liquefaction of gels and the dispersion of solids. When a standing wave is formed in an ultrasonic fluid medium, tiny particles suspended in the fluid are condensed at the wave nodes due to the action of mechanical force, forming periodic accumulations in space. When ultrasonic waves propagate in piezoelectric materials and magnetostrictive materials, the induced electric polarization and induced magnetization are caused by the mechanical action of ultrasonic waves.

Cavitation: When ultrasonic waves act on liquids, a large number of small bubbles can be generated. One reason is that a negative pressure is formed due to the local tensile stress in the liquid, and the reduction of the pressure makes the gas originally dissolved in the liquid supersaturated, and escapes from the liquid to become small bubbles. Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation. Inside the cavity is a liquid vapor or another gas dissolved in a liquid, or it may even be a vacuum. The small bubbles formed by cavitation will continue to move, grow or burst suddenly with the vibration of the surrounding medium. When bursting, the surrounding liquid suddenly rushes into the bubbles to generate high temperature, high pressure, and shock waves at the same time. The internal friction that accompanies cavitation can form charges and cause luminescence due to discharge within the bubble. Most of the techniques for sonication in liquids are related to cavitation.

Thermal effect: Due to the high frequency and high energy of ultrasonic waves, it can produce significant thermal effects when absorbed by the medium.

Chemical effects: The action of ultrasound can promote or accelerate certain chemical reactions. For example, pure distilled water produces hydrogen peroxide after ultrasonic treatment; nitrogen-dissolved water produces nitrous acid after ultrasonic treatment; dye aqueous solution will change color or fade after ultrasonic treatment. The occurrence of these phenomena is always accompanied by cavitation. Ultrasound can also accelerate the process of hydrolysis, decomposition and polymerization of many chemical substances. Ultrasound also has a significant effect on photochemical and electrochemical processes. After the aqueous solution of various amino acids and other organic substances is ultrasonically treated, the characteristic absorption bands disappear and show a uniform general absorption, which indicates that the cavitation has changed the molecular structure.

The beneficial effect of the present invention is that, adopting a washing machine with an ultrasonic device of the present invention realizes the multi-purpose function of one machine, and on the basis of its own function of washing clothes, the cleaning of small items is carried out through the ultrasonic device, For example: gold and silver jewelry, glasses, small children's toys, or some parts of clothing that are not easy to be cleaned separately, such as collars, cuffs, and the edges of clothes. The washing box equipped with an ultrasonic generating device is set in the easy-to-observe control panel seat or on the shell of the washing machine. When the washing machine is sold, the salesperson can also use it to demonstrate the ability of ultrasonic waves to remove stains for customers, with strong visibility. Increase the sense of identity of customers; the invention has simple structure and convenient use.
