Abstract

The present application relates to the technical field of washing machines, and particularly discloses a water level detection device for a pulsator washing machine and the pulsator washing machine. The water level detection device for the pulsator washing machine is characterized in that an insulating body is installed on the outer sidewall of the inner drum of the washing machine, facilitating the installation of the water level detection device, a plurality of conductive holes are arranged on the insulating body, and a conductive connecting piece is arranged between adjacent conductive holes. Since the washing water usually placed in the washing machine is a conductor, when the water level reaches the installation position of the insulating body, the conductive holes are filled with liquid, which makes the plurality of conductive holes in series and conductive, and further makes the entire detection circuit closed and conductive, generating a digital signal. That is, the water level is determined by high and low levels, the water level information is obtained in time, the accuracy and stability of water level detection are improved, and the detection efficiency is improved since the digital signal is directly transmitted to the controller for determination.
