Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] Such as figure 1 The shown device for detecting the water level of a pulsator washing machine includes a Hall sensor 2 arranged on the outer wall of the outer tub 1, and a magnetic buoyancy device 3 that can rise and fall with the water level of the washing machine is arranged on the inner wall of the outer tub 1. The Hall sensor 2 and the The magnetic buoyancy device 3 is turned on at the corresponding position, and the Hall sensor 2 is connected with the controller.

[0022] Further, the Hall sensor 2 includes a first Hall sensor 21 arranged at the bottom of the outer tub 1 and a second Hall sensor 22 arranged at the mouth of the outer tub 1, the first and second Hall sensors 21, 22 There is at least one third Hall sensor 23 between them, and the first, second, and third Hall sensors 21, 22, and 23 are vertically arranged, that is, the first, second, and third Hal...

Abstract

The invention relates to a device and a method of the device for detecting the water level height of a pulsator washing machine. The device comprises a Hall sensor which is arranged on an outer wall of an outer drum. A magnetic floating device which is capable of lifting along with the water level of the washing machine is arranged on an inner wall of the outer drum, the Hall sensor is communicated with the magnetic floating device at a corresponding position, and the Hall sensor is connected with a controller. The technical scheme indicates that the Hall sensor is arranged on the outer wall of the outer drum, and the magnetic floating device which is capable of lifting along with the water level is arranged on the corresponding position on the inner wall of the outer drum. Along with the raising of the water level in the washing machine, the magnetic floating device is communicated with the Hall sensor at different height. Signals are output from the Hall sensor to the controller, and then judgment of the water level height is made by the controller. The device is accurate in judgment, free from influences of factors of the temperature and tightness and high in stability.

Description

technical field [0001] The invention relates to a pulsator washing machine, in particular to a device and a detection method for detecting the water level of a pulsator washing machine. Background technique [0002] At present, most of the water level detection devices of pulsator washing machines on the market use a hose to connect an oscillator. The oscillator can change with the change of the gas pressure in the hose, and then send different oscillation frequencies to the MCU for comparison. Judgment (the water level corresponding to different frequencies has been set in the MCU medium in advance), so that different water levels cause different air pressure in the hose, and the frequency of the water level transmitted to the MCU is also different, so as to achieve the purpose of judging the water level. However, such devices are easily affected by temperature, sealing, etc., and the accuracy and stability are affected. Contents of the invention [0003] The object of t...
