Unfreezing method used for unfreezing device, and refrigerator

Abstract

The invention provides an unfreezing method used for an unfreezing device. the unfreezing device includes a cylindrical body, a device door body, a radio frequency generation module, an upper electrode plate, a lower electrode plate and an infrared sensor; the cylinder body is limited to have an unfreezing cavity used for placing a to-be-processed object and having a forward opening; the device door body is arranged on the forward opening of the unfreezing cavity and used for opening and closing the unfreezing cavity; the upper and lower electrode plates are respectively and horizontally arranged on the top and bottom walls of the unfreezing cavity and electrically connected to the radio frequency generation module; and the infrared sensor is arranged on the inner wall of the unfreezing cavity and used for sensing the size of the to-be-processed object. The unfreezing method includes the following steps: the infrared sensor senses the size of the to-be-processed object; the volume of the to-be-processed object is calculated according to the size of the to-be-processed object; the volume of the to-be-processed object is obtained; and whether the radio frequency generation module starts working is judged, and the working power when the radio frequency generation module works is determined. Compared with unfreezing methods with certain unfreezing power in the prior art, the unfreezing method has better unfreezing effects, and unnecessary energy waste can be avoided.

Description

technical field [0001] The invention relates to the field of thawing, in particular to a method for a thawing device and a refrigerator. Background technique [0002] During the freezing process of food, the quality of food is maintained, but frozen food needs to be thawed before processing or consumption. In order to facilitate users to freeze and thaw food, in the prior art, a heating device or a microwave device is generally provided in the refrigerator to thaw the food. [0003] However, thawing food through a heating device generally requires a long thawing time, and the thawing time and temperature are not easy to control, which will easily cause water evaporation and juice loss in the food, resulting in loss of food quality; It is fast and efficient, so the loss of nutrients in food is very low. However, due to the difference in the penetration and absorption of water and ice by microwaves, and the uneven distribution of internal substances in food, the melted area a...
