Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0025] refer to Figure 1-7 , the water level sensor of the washing machine, including the upper shell 9 and the lower shell 18 connected together, the upper shell 9 and the lower shell 18 are fixed together by a buckle connection, and the upper and lower shells are snapped together by the buckle Together, the assembly efficiency of the sensor is improved. The lower housing 18 has a stepped structure. This design makes the entire sensor structure more compact and reduces the sensor space occupancy. The bottom of the lower housing 18 is provided with an integrally formed air intake channel 1, A detection device is provided between the upper casing 9 and the lower casi...

Abstract

The invention relates to the technical field of water level sensors, in particular to a washing machine water level sensor. The washing machine water level sensor comprises an upper shell and a lowershell connected together. An integrally-formed air inlet channel is arranged at the bottom of the lower shell, a detecting device is arranged between the upper shell and the lower shell, the detectingdevice comprises an inductor coil support and a silica gel membrane, the inductor coil support comprises a cylinder, a PCB support is integrally molded at the upper portion of the cylinder, a PCB isarranged at the upper portion of the PCB support, the PCB is electrically connected with an inductor coil wound around the middle of the cylinder, a membrane gland is integrally formed at the bottom of the cylinder, the membrane gland and the lower shell are fixedly connected together, the silica gel membrane is sealed inside the lower shell through the membrane gland, the air inlet channel is communicated with a cavity at the lower portion of the silica gel membrane, and a magnetic core used in cooperation with the inductor coil is arranged at the upper portion of the silica gel membrane. Thewashing machine water level sensor is more compact in whole structure, more convenient and firm to assemble, reasonable in structural design and longer in service life.

Description

technical field [0001] The invention relates to the technical field of water level sensors, in particular to a washing machine water level sensor. 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. The water level sensor of the washing machine provides a resonant frequency of the LC oscillating circuit to the computer board of the washing machine, and the computer board of the washing machine automatically controls and adjusts the water level of the washing machine according to the resonant frequency signal of the oscillating circuit. The different assembly methods in the sensor manufacturing process will directly affect the use effect of the sensor and affect the assembly efficiency at the same time. Contents of the invention [0003] The object of the present invention is to solve the problem of unreasonable sensor assembly method in th...
