Stereoscopic air circulating device of medicine refrigerator

Abstract

The invention discloses a stereoscopic air circulating device of a medicine refrigerator. The stereoscopic air circulating device comprises a box body. A top fan is mounted on the inner wall of a top plate of the box body. Side fans are mounted in the middles of the inner walls of side plates on the two sides. The top fan and the side fans are each connected to a steering motor through a universal shaft. The steering motors are connected to a control circuit board. The control circuit board is connected to a temperature probe in the box body. Under control of the control circuit board, the top fan, the side fans and the steering motors are controlled by a control program to operate during refrigerator refrigerating, defrosting, door closing and other special time frames, and multiple preset stereoscopic air circulating manners can be achieved. Therefore, the gradient of the temperature in the box body is eliminated, and the temperature seen by a user on an outer temperature display device is actual temperature of points in the box body; and meanwhile, due to the fact that the temperature probe can faster sense temperature changing, compared with a common system, the refrigerating time of a compressor on the interior of the box body is shortened, and the phenomenon of local supercooling in the box body is avoided.

Description

[0001] Technical field: [0002] The invention relates to the field of medical refrigerators, in particular to a three-dimensional wind circulation device for medical refrigerators. [0003] Background technique: [0004] With the development of the domestic medical industry, most hospitals and pharmaceutical factories need to use medical refrigerators. Medical refrigerators mainly store medicines, reagents, vaccines, biological products, and valuable medicines that need to be stored at low temperature. Compared with ordinary civilian refrigerators, Medical refrigerators have stricter temperature control requirements. Once the temperature goes wrong, it may cause drug failure and economic losses, and even endanger the lives of patients. [0005] In the current medical refrigerator, the freezer is in a nearly closed environment, and the colder air sinks due to the specific gravity and gathers at the bottom of the box, while the hotter air gathers at the top of the box. At the s...
