refrigeration unit

Abstract

The invention provides a refrigeration device which comprises a freezing chamber, a freezing circulation system, a supply air path, a tray, a temperature sensor and an air blower. The freezing chamber is used for storing frozen food. The freezing circulation system comprises a compressor, a condenser, an expansion mechanism and an evaporator which are connected together, and refrigeration cold air is produced through cooling of the evaporator. The supply air path is used for conveying cold air produced by the evaporator. The tray is used for being detachably arranged inside the freezing chamber and bearing the frozen food. The tray is provided with multiple through holes. The temperature sensor is used for being arranged inside the freezing chamber and detecting the bottom temperature of the frozen food on the tray. The air blower is used for blowing cold air conveyed by the supply air path towards the tray at the lower portion inside the freezing chamber. Food is efficiently frozen through supercooling, and therefore the supercooling effect is improved.

Description

technical field [0001] The present invention relates to a refrigerating device for cooling and preserving food etc. in a storage room, and more particularly to a refrigerating device having the function of supercooling and freezing the food etc. in the freezing room. Background technique [0002] So far, the freezing method of freezing food through a supercooled state during freezing in the freezer has been used. When this method is used, because the ice crystals are small, it is not easy to damage the cells of the food, so the effect of reducing blood loss can be obtained. Chinese Patent No. 2016100332561 discloses a refrigeration device with the above-mentioned supercooling function. By using a loading plate with through holes to place items that need to be overcooled, the cold air output from the air duct at the top of the loading plate passes through the through holes from the loading Both the upper part and the lower part of the placing plate cool the articles, wherein ...

AI Technical Summary

Problems solved by technology

However, in the actual use process, it is found that there is a large difference between the temperature value detected by the temperature sensor and the actual temperature value of the item on the loading plate, and it is impossible to accurately control the supercooling temperature according to the temperature of the frozen item. Very good supercooling effect
