Directional sound wave thawing control method and refrigerator

Abstract

The invention discloses a directional sound wave thawing control method and a refrigerator, and relates to the technical field of thawing. The unfreezing method has two unfreezing modes, namely a default mode and a user-defined mode. When the user selects the default mode, the temperature of the to-be-unfrozen object at the moment is automatically obtained through the temperature sensor and displayed through the display screen, the unfreezing temperature is automatically set to set the unfreezing process, and then the directional sounder generates sound waves to unfreeze the to-be-unfrozen object; when the user selects the user-defined mode, the user can set an unfreezing process by setting time or unfreezing temperature, and then the directional sounder generates sound waves to unfreeze the to-be-unfrozen article. And when the unfreezing process is completed, displaying is performed through a display screen, and a user is reminded by giving out a prompt tone. According to the invention, rapid and uniform thawing can be carried out by using directional sound waves with strong directivity, and electromagnetic interference can be avoided. And the user can conveniently monitor and operate the unfreezing process through the display screen.

Description

technical field [0001] The invention relates to the technical field of thawing, in particular to a directional acoustic wave thawing control method and a refrigerator. Background technique [0002] Commonly used thawing methods in life include air thawing, warm thawing, circulating thawing and microwave thawing. Air thawing, warm water thawing and circulating thawing do not require special thawing equipment, and the operation is simple and convenient, but the thawing speed is slow. Microwave thawing uses electromagnetic waves to generate a large amount of heat energy to make the food heat from the inside to the outside at the same time, which shortens the thawing time extremely quickly, but this will lead to a large loss of soluble components in the food cells, which will seriously reduce the quality of the food. At present, most of the freezer and refrigerator products on the market are equipped with superconducting disks to meet the needs of daily food thawing, improve th...

Problems solved by technology

The patent document CN109619373B generates ultrasonic signals through the ultrasonic generating module, but because the sound waves use multiple propagation directions to thaw the object to be treated, although the thawing is more uniform, it will cause damage to other electronic devices, and even the contacts will fall off

In addition, the patent document CN109619373B can only operate according to the thawing process preset by the system, but the temperature of the object to be processed after thawing required by the user is different, which cannot meet the diverse needs of the user
