Refrigerating equipment with overcooling function

Abstract

The invention provides refrigerating equipment with an overcooling function. The refrigerating equipment comprises a refrigerating chamber for containing refrigerated objects, a refrigerating circulating system, a supply air way, a tray, a temperature sensor and air supply machines, wherein the refrigerating circulating system comprises a compressor, a condenser, an expansion mechanism and an evaporator which are connected together, and refrigerating cold air is generated through cooling of the evaporator; the supply air way is used for conveying the cold air generated by the evaporator; the tray is arranged in the refrigerating chamber and used for containing the refrigerated objects, the tray is provided with multiple through holes, an air supply cavity is formed in the bottom of the tray, the air supply cavity is used for receiving the cold air conveyed by the supply air way, and the cold air is exhausted upwardly through the through holes from the bottom of the tray; the temperature sensor is arranged on the refrigerating chamber, located below the tray and used for detecting the bottom temperature of the refrigerated objects on the tray; and the air supply machines are used for blowing the cold air conveyed by the supply air way to the tray below the air supply machines in the refrigerating chamber. By the adoption of the refrigerating equipment with the overcooling function, the refrigerated food is overcooled efficiently, and the overcooling 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, in particular to a refrigerating device with a supercooling function 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 Items are refrigerated on both the upper and lower portions of t...

Problems solved by technology

However, in the actual use process, it is found that the amount of cold air entering the bottom from the through hole of the mounting plate is relatively small, and the effect of supercooling is still not well achieved.

In addition, 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
