The invention discloses a household appliance and a control method for the household appliance. The household appliance comprises: a cavity body having a water-holding cavity; a water pipe connected to the cavity body and communicating with the water-holding cavity; Cavity, the water pipe is provided with a water valve; detection device, the detection device is located on the water pipe and is located on the side of the water valve close to the water chamber, the detection device includes for detecting the The pressure detection part of the fluid pressure in the water pipe and the frequency spectrum detection part suitable for generating vibration under the impact of the fluid; the controller, and the controller is in communication connection with the detection device. According to the household appliance of the present invention, by installing a detection device on the water pipe, and using the detection device to simultaneously detect the water flow pressure in the water pipe and the frequency spectrum value under the impact of the water flow, it is possible to judge whether the household appliance has a water leakage point through the pressure change and the frequency spectrum value change , to realize the effective detection of water leakage of household appliances.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a household appliance and a control method for the household appliance. Background technique [0002] With the improvement of people's living standards, the requirements for the safety attributes of home appliances are very high. At present, the biggest risk of dishwashers on the market is that huge losses are caused by water leakage from the whole machine. There are many reasons for water leakage, such as poor interface, poor sealing, poor welding, rust and scaling, etc., which cannot be prevented in advance through a certain technology. Therefore, it is very important how to stop electricity consumption and inform users in the first place when water leaks. [0003] The related art provides a situation of judging whether there is water leakage in the pipeline by detecting the flow change before and after. Due to the limited accuracy of the flow sensor, water leak...
