Abstract

The invention provides a waterway abnormality detection method and device. The abnormal detection method of the waterway includes: using the pressure sensor at the water inlet to collect the first pressure value, and the pressure sensor at the water outlet to collect the second pressure value, the waterway includes a main water valve, and the water inlet and water outlet of the main water valve are respectively A pressure sensor is provided; the opening and closing state of the main water valve is obtained, and when the main water valve is opened, it is judged whether the first pressure value is equal to the second pressure value, and if the result is no, it is determined that the waterway is abnormal. According to the solution of the present invention, by judging whether the first pressure value at the water inlet of the main water valve is equal to the second pressure value at the water outlet, it is possible to determine whether there is any abnormality in the waterway, so that water leakage in the waterway can be found in time, and water leakage in the waterway can be avoided for a long time Serious losses to users.

Description

technical field [0001] The invention relates to the field of water leakage detection, in particular to a waterway abnormality detection method and device. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's pace of life is getting faster and faster, so they are more and more willing to buy a lot of food and put it in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily life. . [0003] Moreover, current refrigerators have more and more functions to meet different needs of users. For example, a refrigerator equipped with an ice-making system can provide ice cubes to users. In the ice-making system of the refrigerator, the waterway is a key system component. If the waterway leaks or fails, it will lead to serious consequences. The current ice-making system cannot monitor, discover and prevent waterway leakage, and it is easy to affect the w...
