Embodiment Construction

[0036] In this example, if figure 1 As shown, a refrigerator failure operation method is applied to a main control circuit board, a display board, a temperature sensor, a heating device, a refrigeration system, a door switch, an ambient temperature sensor, a refrigeration temperature sensor, a freezing temperature sensor and a defrosting temperature sensor In the composed refrigerator control system, the refrigerator control system takes the main control circuit board as the control core. The ambient temperature sensor, refrigerating temperature sensor, freezing temperature sensor, defrosting temperature sensor, and door switch are used as detection devices. The main control circuit board collects information through the detection devices to determine whether the refrigerator is running normally, thereby controlling the operation of the heating device and the refrigeration device. Once a fault is detected, it will operate according to the corresponding fault operation mode, an...

Abstract

The invention discloses a fault operation method for refrigerators, and a refrigerator using the fault operation method. The fault operation method is applied to a refrigerator control system consisting of a main control circuit board, a display board, a temperature sensor, a heating device, a refrigerating system, a door switch, an ambient-temperature sensor, a refrigerating-temperature sensor, a freezing-temperature sensor, and a defrosting-temperature sensor. The fault operation method is characterized in that corresponding fault operation manners are set according to different fault modes of the refrigerator. According to the fault operation method disclosed by the invention, aiming at different fault types of the refrigerator, the corresponding fault operation modes are set, so that the refrigerator is guaranteed to more safely and reliably work under fault states.

Description

technical field [0001] The invention relates to a refrigerator control method, in particular to a refrigerator operating method in various fault states and a refrigerator using the method. Background technique [0002] Traditional mechanical refrigerators have simple structures and few functions. Most of them do not have fault detection devices. When a refrigerator fails, it is difficult for users to detect it. If it takes a long time, it will cause more serious safety accidents. [0003] With the development of society and the advancement of science and technology, the popularity of electronically controlled refrigerators has increased. Refrigerators have more and more functions, but the corresponding failure rate is also getting higher and higher. Ordinary electronically controlled refrigerators are only tested for simple functions such as temperature sensors and door switch alarms. There is no prompt for insufficient refrigeration and defrosting failures of the refrigera...
