Abstract

The invention is applicable to the technical field of electronic circuits, and provides a dust amount detection method, device and circuit, and a household appliance. The method comprises the following steps: collecting and calculating the dust amount at a dust suction port of a dust box in real time according to the detected working state of infrared geminate transistors, wherein the infrared geminate transistors are arranged at the dust suction port of the dust box; integrating and accumulating the collected dust amount to obtain the total dust amount; judging whether the accumulated total dust amount reaches a target dust amount or not; and if so, sending out prompt information to prompt a user that the dust box is full of dust. According to the invention, the working state of the infrared geminate transistors is used for detection, so that the dust amount at the dust suction port of the dust box can be rapidly and accurately detected, and the dust amount can be subjected to integral accumulation, so that the total dust amount in the dust box can be detected, when it is detected that the total dust amount in the dust box reaches the target dust amount, a user can be prompted to clean the dust box, and the problem that existing dust amount detection is inaccurate is solved.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to a method, a device, a circuit, and a household appliance for detecting the amount of dust. Background technique [0002] With the development of electronic technology, and in order to reduce the work of users, more and more household appliances such as washing machines, dishwashers, and floor sweepers are widely used by users. [0003] When the existing sweeping machines are working, the high-speed rotation of the motor creates a vacuum in the main machine, and the resulting high-speed airflow is used to suck dust and garbage from the suction port. Due to the limited capacity of the dust box containing dust inside it, it is necessary to regularly clean the dust box. Therefore, it is necessary to detect the amount of dust when the sweeper is working, so as to achieve more accurate dust cleaning of the dust box. [0004] Existing sweeping machines detect t...
