Example 2

The present embodiment describes the control method of the circular refrigerator according to the present invention in detail.

The control method of the circular refrigerator in the technical scheme of the embodiment 1 comprises the following steps:

when the circular refrigerator is in an operating state, the motor 60 operates and drives the storage rack 20 to perform a circular rotation motion, and cool air is blown onto the storage rack 20 at least from a circumferential direction of the storage rack 20.

The first sensor monitors the temperature in the box body in real time. The first sensor is for example a temperature sensor.

When the temperature in the box body reaches the preset value, the compressor 80 stops working, and when the temperature in the box body does not reach the preset value, the compressor 80 continues working and executes in a circulating mode, so that the temperature in the box body is kept at the preset temperature.

In the control method of the circular refrigerator in any one of the embodiment 1, the cold air in the airflow space 101 is controlled to blow onto the storage rack 20 at least from the circumferential direction of the storage rack 20, so that the food materials can be cooled uniformly, and the storage effect of the food materials can be improved; on the other hand, the control method of the embodiment can make the food material contact the cold air more uniformly by controlling the storage rack 20 to perform the circular rotation motion, so as to further improve the storage effect of the food material. The control method of the circular refrigerator in the embodiment solves the technical problem that the cooling of food materials in the refrigerator is uneven due to the fact that the air outlet mode of the traditional refrigerator is from back to front in the prior art.

According to a preferred embodiment, the control method of the circular refrigerator further comprises the steps of:

the second sensor monitors the state of the box door in real time. The second sensor is for example a position sensor.

When the door is in the open state, the motor 60 stops working, and when the door is in the closed state, the motor 60 continues working.

In the control method of the circular refrigerator in the preferred technical scheme of this embodiment, the state of the door is monitored in real time by the second sensor, and when the door is in the open state, the motor 60 stops working, so that the storage rack 20 stops rotating, and a user can conveniently access food materials; when the door is closed, the motor 60 continues to operate, so that the storage shelf 20 keeps circular rotation, and the food material can contact with cold air more uniformly.

Fig. 6 shows a flowchart of the operation of the circular refrigerator. As shown in fig. 6, when the circular refrigerator is in normal operation and a user does not take and take food, the motor 60 operates and drives the storage rack 20 to perform circular rotation, so that the food on the storage racks 20 in different layers can be cooled uniformly, and the refrigeration effect is improved. When the user accesses the food materials, the state of the food materials is changed after the box door is opened and is monitored by the second sensor, the main control system regulates and controls the motor 60 to stop working, the motor 60 is in a non-self-locking state, and the user can manually rotate the storage rack 20 and access the food materials. After the food material is stored and taken out, the motor 60 normally works, and the storage rack 20 continues to perform circular rotation motion. A first sensor is arranged in the box body, and when the first sensor detects that the temperature in the box body reaches a preset value, the compressor 80 is stopped; when the first sensor detects that the temperature inside the tank does not reach the preset value, the compressor 80 keeps operating.
