Unfreezing device and refrigerator having the same

Abstract

The invention provides an unfreezing device. The unfreezing device includes a cylinder body, a device door body, a radio frequency generation module, an upper electrode plate and a lower electrode plate; the cylinder body is limited to have an unfreezing cavity having a forward opening and used for placing a to-be-processed object; the device door body is arranged on the forward opening of the unfreezing cavity and used for opening and closing the unfreezing cavity; the radio frequency generation module is configured to generate radio frequency signals; the upper and lower electrode plates arerespectively and horizontally arranged on the top and bottom walls of the unfreezing cavity and electrically connected to the radio frequency generation module to generate radio frequency waves of corresponding radio frequency in the unfreezing cavity according to the radio frequency signals and unfreeze the to-be-processed object in the unfreezing cavity; and the radio frequency generation module is configured to not work when the device door body is opened. Through the configuration of the radio frequency generation module to not work when the device door body is opened, the radio frequencywaves can be prevented from leaking to create harm to human bodies when users open the device door body during an unfreezing process, and therefore, the safety of the unfreezing device can be enhanced.

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...
