Refrigerator energy-conservation control method and refrigerator

Abstract

The invention discloses a refrigerator energy-conservation control method and a refrigerator. Adjustment of a refrigerator energy-conservation mode is achieved through an electronic temperature control way, so that tediousness of manual operation and installation and usage of a mechanical switch are avoided. The refrigerator energy-conservation control method comprises the steps that an induction signal output by a temperature sensor is received; whether a door body of the refrigerator is opened or not is judged based on the induction signal; if yes, door opening information is recorded, and the operating time period and the non-operating time period of the refrigerator are analyzed based on the door opening information; and the refrigerator is controlled to be adjusted to the energy-conservation mode in the non-operating time period. Opening of the door body is judged through the change, induced by the temperature sensor, of the temperature in a box body of the refrigerator, , so that energy-conservation arrangement of the refrigerator in the non-operating time period is achieved through the electronic temperature control way.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a refrigerator energy-saving control method and the refrigerator. Background technique [0002] In supermarkets, shopping malls and other occasions, freezers are used to refrigerate items such as beverages and food for customers to purchase. The compressor refrigeration cycle system in the freezer is used to reduce the temperature in the cabinet, so that the items maintain a cool taste or freshness at the refrigerated temperature. [0003] During the business hours when customers purchase, the refrigerators are opened more frequently, and the cold air leaks more. In order to maintain the refrigeration temperature requirements, the compressor refrigeration cycle system needs to operate at high frequency to keep the low temperature; but during non-business hours, the refrigerators If it is always closed and there is no leakage of cold air, the compressor refriger...

AI Technical Summary

Problems solved by technology

[0004] In the existing method of controlling the energy-saving mode during non-business hours, manual control requires managers to manually adjust the energy-saving mode during non-business hours, and cancel the energy-saving mode during business hours, which requires manual timing operations, and there are gaps; The automatic control method is to set a mechanical switch on the door of the freezer. The freezer controller counts the business hours and non-business hours by detecting the switching frequency of the mechanical switch, and controls the operation of the compressor and evaporating fan during the business hours to maintain the refrigeration temperature. Requirements, such as 2-7 degrees; and during non-business hours, control and stop the operation of compressors, evaporating fans, etc., and adjust the temperature in the freezer to 8-14 degrees in the standby mode to achieve the purpose of energy saving, but This method of judging the business status by detecting the switching frequency of the mechanical switch requires additional mechanical switch components in the freezer, and the need to realize the circuit of the mechanical switch and the control circuit, which increases the complexity of the structural design.
