Household scrubber and self-cleaning method thereof

Abstract

The invention discloses a self-cleaning method of a household scrubber. The self-cleaning method comprises the following steps: (1) closing a liquid spraying device; (2) keeping a motor of a main machine to be started, and sucking a liquid flowing through a rolling brush into a liquid suction pipeline; and (3) starting the liquid spraying device again, and spray the liquid to the rolling brush at least once; and then closing the liquid spraying device. After the liquid spraying device, the rolling brush motor and the main machine motor are closed, the liquid spraying device is started again, the liquid is sprayed to the rolling brush for at least one time, then the liquid spraying device is closed, and the whole self-cleaning operation is finished so that dirt (especially garbage with high viscosity) can be prevented from being adhered to a nozzle, and the problem that the nozzle is blocked is avoided.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a household floor washing machine and a self-cleaning method thereof. Background technique [0002] In the prior art, scrubbers are generally divided into commercial scrubbers and household scrubbers. Commercial scrubbers are generally used in relatively large factories, garages, shopping malls, supermarkets, etc., while household scrubbers are generally suitable for large areas. Relatively small (generally less than 200 square meters) family. [0003] For household floor washing machines, its structure mainly includes the main body of the washing machine and the floor brush. The floor brush is equipped with a roller brush for cleaning the ground; the main body of the floor washing machine is equipped with a water tank (to supply water to the roller brush) and a sewage tank ( to collect sewage); it is also provided with a controller, a liquid spraying device, a rolling brush ...

AI Technical Summary

Problems solved by technology

However, in practical applications, the following problems are found: due to the continuous rotation of the roller brush during the self-cleaning process, the dirt (such as liquid dirt and / or solid particles) on it will be thrown out, and these dirt Sometimes it will be blocked on the nozzle of the liquid spraying device, causing the nozzle to be blocked; in practical application, if the liquid spraying device is in the process of spraying liquid, the sprayed liquid can wash away these dirt; and in practical application, due to The roller brush has the inertia of rotation. When the self-cleaning operation is completed, the inertial rotating roller brush may throw the stolen goods onto the nozzle, especially when dealing with viscous garbage (such as porridge and other kitchen waste, mud, etc.) , after the garbage sticks to the nozzle, it will dry after a while, and it will block the nozzle after drying
