Open type refrigerated cabinet and control method thereof

Abstract

The invention discloses an open type refrigerated cabinet and a control method thereof. The open type refrigerated cabinet comprises a cabinet body, a rolling shutter device, a motor, an inductor anda controller. The cabinet body is provided with an open type display surface, the rolling shutter device is provided with a transparent rolling shutter, the rolling shutter device is disposed on the cabinet body, the motor is electrically connected to the rolling shutter device, and the controller is electrically connected to the inductor and the motor. The inductor is used to induct whether at least one person body is located at front of the open type display surface of the cabinet body, and, when the human body is located at the front of the open type display surface of the cabinet body, thecontroller is used to drive the motor to control the rolling shutter device so that the transparent rolling shutter keeps at a rollback state and then the open type display surface is at an open state. The n open type refrigerated cabinet and the control method thereof can reduce energy waste and improve the heat insulation effect.

Description

[0001] The present invention is an application date: February 10, 2014, application number: 2014100465795, title of invention: open refrigerator and its control method. technical field [0002] The invention relates to a refrigerator, in particular to an open refrigerator and a control method thereof. Background technique [0003] Refrigerated cabinets are used by stores to display fresh foods, etc., to keep these foods fresh, and to sell them. Refrigerators can be divided into closed refrigerators and open refrigerators. The closed refrigerators have glass doors that can be opened. When not in use, the glass doors are in a normally closed state to prevent the cold air from overflowing. The cabinet has better heat preservation effect. However, consumers need to manually open the glass door, so it is inconvenient to take the food displayed in the cabinet.

AI Technical Summary

Problems solved by technology

When the store is in the off-peak hours of business or when no customers come to the store, the cold air in the cabinet is still continuously spilled from the open display surface, which is usually open, resulting in waste of energy and the insulation effect of the open refrigerator poor

[0006] In order to solve the above-mentioned problems of open refrigerators, those skilled in the art have tried their best to find a solution, but no suitable method has been developed for a long time.
