Description

Washing machine with ultrasonic washing function

Technical field

The invention belongs to the technical field of washing machines and discloses a washing machine with an ultrasonic washing function.

Background technique

The ultrasonic wave has a cleaning function, and the principle is that the ultrasonic generating device includes an ultrasonic generator and an energy converter, and the high-frequency oscillation signal emitted by the ultrasonic generator is converted into a high-frequency mechanical oscillation by the energy converter to propagate to the medium, and the ultrasonic wave in the cleaning solvent is The frontward radiation between the dense and dense phases in the cleaning liquid causes the liquid to flow and generates tens of thousands of tiny bubbles. The tiny bubbles existing in the liquid vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles rapidly grow. Then suddenly closes, creating a shock wave when the bubble is closed, generating thousands of atmospheric pressures around it, destroying the insoluble dirt and dispersing them in the cleaning solution, when the group particles are wrapped by the oil and adhere to the surface of the cleaning member, The oil is emulsified, and the solid particles are detached, thereby achieving the purpose of purifying the surface of the cleaning member.

In view of the excellent cleaning function of ultrasonic waves, there is no shortage of washing machines that use ultrasonic cleaning, but it is mainly for the decontamination treatment of clothes, and there is no washing machine with ultrasonic washing function specially designed for small objects such as jewelry and glasses.
