Problems solved by technology

[0002] During the use of household refrigerators, refrigerator refrigeration and defrosting system failures occur from time to time. Once a failure occurs, refrigerator refrigeration and defrosting will not be able to operate normally and efficiently
For example, when the temperature sensor fails, the compressor or defrost heater can only work for a fixed period of time before the temperature sensor is replaced. This way of working can neither control the cooling of the refrigerator compartment nor ensure that the evaporator The frost is completely melted, which affects the normal cooling efficiency and is not conducive to the storage of indoor food in the refrigerator

Abstract

The invention provides a refrigeration device. The refrigeration device comprises a chamber for storing objects, a first temperature sensor for detecting the temperature of the chamber, an evaporatorfor cooling the chamber, and a second temperature sensor for detecting the temperature of the evaporator; when the first temperature sensor cannot normally work, a control unit controls refrigerationof the chamber based on the temperature, detected by the second sensor, of the evaporator; and when the second temperature sensor cannot normally work, the control unit controls defrosting of the evaporator based on the temperature, detected by the first sensor, of the chamber in the defrosting phase of the evaporator. Before maintainers replace the broken sensor, continuous normal operation of arefrigerator can be guaranteed according to the temperature information measured by the other temperature sensor.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a household refrigerator and a control method thereof. Background technique [0002] During the use of household refrigerators, failures of the refrigeration and defrosting systems of the refrigerators occur from time to time. Once a failure occurs, the refrigeration and defrosting of the refrigerator cannot be performed normally and efficiently. For example, when the temperature sensor fails, the compressor or defrost heater can only work for a fixed period of time before the temperature sensor is replaced. This way of working can neither control the cooling of the refrigerator compartment nor ensure that the evaporator The frost is completely melted, which affects the normal cooling efficiency and is not conducive to the storage of indoor food in the refrigerator. Contents of the invention [0003] The problem solved by the invention is how to ensure that the refrigera...
