Water level sensor structure

Abstract

The invention provides a water level sensor structure which is applied to the technical field of washing machine part structures. An air inlet cavity (2) of a sensor casing (1) of the water level sensor structure is communicated with an air chamber of a washing machine; an internal capacitor (3) and an inductance coil (4) which are arranged in the sensor casing (1) are connected to form an oscillating circuit (5); an inverter (6), a resistor (7) and an external capacitor (8) in the sensor casing (1) can form a control circuit (9); the control circuit (9) is arranged in the sensor casing (1), and the control circuit (9) is connected with the oscillating circuit (5). The water level sensor structure is simple in structure, improves the timeliness and the accuracy of receiving and converting inductance value signals of the inductance coil, enables a washing machine computer panel to accurately control the washing machine water level according to the signals of the water level sensor and effectively improves the control performance of the washing machine.

Description

technical field [0001] The invention belongs to the technical field of washing machine component structures, and more specifically relates to a water level sensor structure used in washing machine water level control and regulation. Background technique [0002] The washing machine water level sensor has a simple structure and convenient control, and is widely used in low-end, mid-end, and high-end washing machines. In the prior art, the digital sensor of the washing machine can only provide an LC oscillation circuit frequency to the computer board of the washing machine, and the computer board of the washing machine controls and adjusts the water level of the washing machine according to the frequency signal of the oscillation circuit. However, the water level sensor of the washing machine with this structure cannot correct the frequency of the oscillating circuit, so the accuracy of the water level sensor of the washing machine cannot be guaranteed, which affects the overa...
