Abstract

The invention discloses a method and device for prejudging domestic appliance faults and a domestic appliance. The method comprises the following steps that operation parameters of the domestic appliance are obtained after the domestic appliance is powered on, wherein the operation parameters comprise the first operation parameter and the second operation parameter; according to the first operation parameter and a preset trend character algorithm equation, theoretical operation parameters of the domestic appliance are calculated; according to a preset error calculation way, the theoretical operation parameters and the second operation parameter, the error value of the domestic appliance is calculated, and whether the error value is in a preset normal range or not is judged; if the error value is not in the preset normal range, a knowledge base of the domestic appliance is called according to the error value, and therefore information of abnormal components of the domestic appliance is obtained; and early-warning information is generated according to the information of the abnormal components and sent. According to the method, faults of the domestic appliance can be prejudged, the safety of the domestic appliance is improved, and user experience is also improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for predicting failures of household appliances, a device for predicting failures of household appliances and a household appliance. Background technique [0002] With the improvement of living standards, more and more household appliances such as air conditioners and air purifiers have entered various families. However, in the related art, the household appliance reports a fault only when an operation fault occurs, which is low in safety and is not conducive to user experience. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide a method for predicting failures of household appliances, which can realize the prediction of failures of household appliances, which not on...
