Refrigerator failure judgment method, server and computer-readable storage medium

Abstract

The invention discloses a refrigerator failure judgment method. The refrigerator includes a storage room, an evaporator, a first temperature sensor and a second temperature sensor. The judging method includes: obtaining the difference between multiple first temperature values ​​and multiple second temperature values ​​and preset temperature values; Whether the proportion of the failure of the valve unable to switch to the refrigeration side is greater than the first preset proportion; and when the proportion of the failure of the solenoid valve unable to switch to the refrigeration side of the refrigerator is greater than the first preset proportion, it is judged that the failure of the solenoid valve cannot be switched to the refrigeration side of the refrigerator . In addition, the invention also discloses a server and a computer-readable storage medium. The judging method, server and computer-readable storage medium of the present invention use a support vector machine classifier to judge whether there is a fault that the solenoid valve cannot be switched to the refrigerated side in the refrigerator, thereby helping maintenance engineers to understand the cause of the failure in advance, bringing all spare parts, and effectively improving maintenance engineers. One home repair rate.

Description

technical field [0001] The invention relates to household electrical appliances, in particular to a method for judging refrigerator faults, a server and a computer-readable storage medium. Background technique [0002] At present, traditional refrigerators are already facing development bottlenecks. Problems such as lack of product technical standards, low consumer awareness in the market, high product prices, and poor experience restrict the development of traditional refrigerators. The growing new demands of users force the refrigerator industry to Intelligent transformation. When a household appliance breaks down, it will bring great inconvenience to people's daily life. With the rapid development of the home appliance industry, the home appliance repair industry has also made great progress, but there are still maintenance engineers who cannot know the cause of the failure in advance.

Problems solved by technology

[0002] At present, traditional refrigerators are already facing development bottlenecks. Problems such as lack of product technical standards, low consumer awareness in the market, high product prices, and poor experience restrict the development of traditional refrigerators. The growing new demands of users force the refrigerator industry to Intelligent direction transformation

When a household appliance breaks down, it will bring great inconvenience to people's daily life. With the rapid development of the home appliance industry, the home appliance repair industry has also made great progress, but there are still maintenance engineers who cannot know the cause of the failure in advance. Unable to bring spare parts

The failure of the solenoid valve to switch to the refrigerated side is a common fault in refrigerators. Repairing such faults requires special tools such as spare parts welding guns, vacuum pumps, etc. If the cause of the fault cannot be known in advance, a second visit is often required to reduce the successful repair rate of the first visit

[0003] Although the number of smart refrigerators is increasing rapidly at present, smart refrigerator products only have the function of uploading fixed types of fault codes, and cannot perform fault diagnosis, so that maintenance engineers can better understand the cause of the fault and complete a successful on-site repair.

At present, the application of fault diagnosis on home appliances only has fixed fault codes, which are limited to simple faults such as sensor faults and door opening timeouts. At present, there is no online detection method for the solenoid valve that cannot be switched to the refrigeration side, which means that the solenoid valve of the refrigerator is switched. Switchover failure detection (failure to switch to refrigerated side, stuck on frozen side) is valuable and necessary
