Refrigerator with main cover and subsidiary cover

Abstract

The invention provides a refrigerator with a main cover and a subsidiary cover. The refrigerator comprises an insulated box body, an insulated cover body and at least one dilution refrigeration element, wherein the insulated cover body can be rotatably pivoted on the insulated box body so that the insulated cover body is closed on the insulated box body to form a closed space; the insulated cover body comprises a base and a cover plate, the base is provided with a groove, and the cover plate can be rotatably pivoted on the base so that the cover plate is closed in the groove of the base; the groove is provided with a plurality of air vents; and the dilution refrigeration element is arranged in the groove. The insulated cover body can be designed into the main cover and the subsidiary cover and forms a closed storage space together with the insulated box body, and the main cover and the subsidiary cover can be used for placing dilution refrigeration elements and separating stored articles with the replaceable dilution refrigeration elements to avoid polluting the dilution refrigeration element because of condensed water.

Description

technical field [0001] The present invention relates to a cold storage box, in particular to a cold storage box with a double cover. Background technique [0002] Traditional cold storage boxes store low-temperature items or fresh-keeping items for a short period of time, and then deliver them to customers, or serve as a temporary fresh-keeping function for food in stores or sales. In the traditional cold storage box, a cold storage device is placed above the thermal insulation items. If you want to access the items, you must first remove the cold storage unit, which is very inconvenient to operate. And when some cold storage boxes use dry ice as a cold storage material, a dry ice tray is usually placed above the items to hold the dry ice. However, the dry ice tray must be removed first to access the items, which is also very inconvenient to operate. Regardless of whether the cold accumulator is placed on the top or side of the box, if the cold storage material is not clean...

AI Technical Summary

Problems solved by technology

However, every time the dry ice is placed and replaced, the coffin lid needs to be opened, which also causes troubles for the staff and family members

There is also a coffin with an electric refrigeration system. The refrigeration system is integrated with the coffin. The refrigeration system must be powered by electricity, but the refrigeration system needs to dissipate heat. Therefore, there will be noise and power wiring problems during operation.
