Defrost device and refrigerator having the same

Abstract

The invention provides a thawing device. The thawing device includes: a cylinder body, which defines a thawing chamber with a forward opening, and the thawing chamber is used to place the object to be treated; the device door is arranged at the forward opening of the thawing chamber for opening and closing The thawing chamber; the radio frequency generating module configured to generate radio frequency signals; the upper electrode plate and the lower electrode plate are respectively horizontally arranged at the top wall and the bottom wall of the thawing chamber, and are respectively electrically connected with the radio frequency generating module, so that according to the radio frequency The signal generates a radio frequency wave of a corresponding frequency in the thawing chamber, and thaws the to-be-processed object in the thawing chamber; and the tray is arranged in the thawing chamber to carry the to-be-processed object; and at least part of the tray is made of transparent material to reduce the Electromagnetic losses generated. The invention adopts the tray made of transparent material to carry the object to be processed, which can reduce the electromagnetic loss generated by the tray, make the object to be processed absorb more energy of radio frequency waves, and improve the thawing efficiency of the thawing device.

Description

technical field [0001] The invention relates to the field of thawing, in particular to a thawing device and a refrigerator with the thawing device. 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 me...
