Unfreezing device, refrigerator and unfreezing control method of refrigerator

Abstract

The invention provides an unfreezing device, a refrigerator and an unfreezing control method of the refrigerator. The unfreezing device comprises a shell, a first electrode board, a second electrode board and a high-frequency power supply, the first electrode board is arranged at the top of the inner wall of the shell, the second electrode board is arranged at the bottom of the inner wall of the shell, the first electrode board and the second electrode board are connected with two ends of the high-frequency power supply respectively, high-frequency alternating electric fields are generated between the first electrode board and the second electrode board when the high-frequency power supply operates, so that high-frequency electromagnetic waves are generated and acted onto unfrozen food, insulating materials are arranged between the first electrode board and the inner wall of the shell and the second electrode board and the inner wall of the shell and on the lower side of the first electrode board and the upper side of the second electrode board, and the unfrozen food is placed on the insulating materials of the upper side of the second electrode board. The unfreezing device is simple in structure, the high-frequency electromagnetic waves are rapidness and uniformity in unfreezing, and nutrient loss is low.

Description

technical field [0001] The invention relates to the technical field of current sampling, in particular to a thawing device, a refrigerator and a thawing control method thereof. Background technique [0002] The food in the freezer compartment of the refrigerator is in a frozen state and cannot be eaten directly, so it must be thawed before cooking frozen meat and other foods, and the thawing process also brings inconvenience to users. From the perspective of heat transfer, thawing can be divided into two categories: thawing from the outside to the inside and simultaneous thawing from the inside and the outside. The thawing from the outside to the inside is also called the external heating method: the heat is transferred from the higher temperature medium to the surface of the frozen product, and the heat is gradually transferred from the surface to the center. Air thawing, water thawing, infrared radiation thawing, and metal plates are all thawing methods from the outside t...
