Water level judging device and method for washing device

Abstract

The invention discloses a water level judging device and a water level judging method for a washing device, relating to the technical field of washing devices. The water level judging device for the washing device comprises a floating device used for determining the water level in a water tank of the washing device, at least one detection device used for feeding back water level signals of the floating device, and a controller, wherein the floating device is mounted in the water tank, the at least one detection device is mounted outside the water tank, the at least one detection device is matched with the floating device, and the at least one detection device is electrically connected with the controller. The invention further provides a water level judging method adopting the water level judging device for the washing device. The water level judging device for the washing device provided by the invention is simple in structure, a water level switch or a water level sensor used for judging the water level is not needed, and the independent pore opening operation for the water tank is not needed, thus the potential safety hazard of water leakage can be effectively avoided, meanwhile, the manufacturing cost can be greatly reduced, and the assembling procedure is reduced.

Description

technical field [0001] The invention relates to the technical field of washing devices, in particular to a water level judging device of a washing device and a water level judging method applied to the water level judging device of the washing device. Background technique [0002] At present, in most washing device products, the determination of the water level is generally realized by a water level sensor or a water level switch: when the inflow reaches a certain amount of water, the water level switch action or the water level sensor feeds back information to the control board of the whole machine. These two methods of judging the water level all need to lead out the air conduit on the water tank to be connected to the water level switch or the water level sensor, so that the water level control when the water is fed is realized during the operation of the complete machine. Since these two water level determination methods both open a hole at one end of the water tank, the...

AI Technical Summary

Problems solved by technology

Since these two water level determination methods both open a hole at one end of the water tank, the water tank and the component end need to be sealed with pipe clamps or other methods, which has hidden dangers of water leakage, increases the cost of the whole machine, and increases the assembly process

[0003] Based on the above description, there is an urgent need for a new water level judging device for a washing machine to solve the hidden danger of water leakage caused by the existence of a water level switch or a water level sensor in the existing dishwasher water level judging device, which requires high manufacturing costs and difficult assembly.
