Refrigeration equipment and its control methods

By setting up a secondary storage compartment and a damper assembly in the refrigerator, the system utilizes ambient air to naturally cool high-temperature food and switches to cold air cooling when appropriate. This solves the problem of high-temperature food affecting refrigeration efficiency and energy consumption, achieving efficient refrigeration and preservation.

AI Technical Summary

Technical Problem

When placing hot food in existing refrigerators, the low-temperature environment is disrupted, affecting the refrigeration and preservation effect and increasing energy consumption. In addition, users often forget to refrigerate the food after it has cooled down, causing the food to spoil.

Method used

A secondary storage compartment is set up in the refrigerator, and the circulation of ambient air or cold air is controlled by a damper assembly. The ambient air is used to naturally cool hot food, and the system switches to cold air cooling when the food is at a suitable temperature. Combined with sensors to detect temperature and the presence of items, energy consumption and refrigeration effect are optimized.

Benefits of technology

It allows for the placement of high-temperature foods without affecting the refrigeration effect of the main storage compartment, thus preventing food spoilage, saving energy, and improving refrigeration efficiency.

Abstract

The present application provides a refrigeration device and a control method thereof. The refrigeration device comprises a device body and a damper assembly mounted to the device body, the device body defining a main storage chamber and a sub storage chamber, and the damper assembly being configured to selectively allow cold air in the refrigeration device or ambient air at ambient temperature to flow through the sub storage chamber. The control method comprises: determining whether the temperature in the sub storage chamber is greater than the ambient temperature outside the refrigeration device; in response to the temperature in the sub storage chamber being greater than the ambient temperature, controlling the damper assembly to allow ambient air at ambient temperature to flow through the sub storage chamber; and in response to the temperature in the sub storage chamber not being greater than the ambient temperature, controlling the damper assembly to allow cold air in the refrigeration device to flow through the sub storage chamber. The refrigeration device of the present application can allow high-temperature foodstuffs to be placed therein, and after the high-temperature foodstuffs are naturally cooled, the foodstuffs can be refrigerated and preserved.
