Description

Technical Field

[0001] The utility model relates to the technical field of water level sensors, in particular to a washing machine water level sensor with a stable structure. Background Art

[0002] The washing machine water level sensor is responsible for monitoring and controlling the water level inside the washing machine to ensure that the water level is always kept within the appropriate range in different washing programs. The application of this technology enables the washing machine to automatically adjust the water level according to the required washing volume, which improves the washing effect while saving water resources. Washing machine water level sensors usually adopt pressure sensors, float sensors, capacitive sensors and other types. The pressure-type washing machine water level sensor consists of an air chamber, a diaphragm, a magnetic ring, and a coil. The air in the air chamber is compressed as the water level rises, resulting in an increase in air pressure. The diaphragm, the magnetic ring, and the coil form an LC circuit with variable inductance. As the air pressure increases, the diaphragm will be pushed, which in turn drives the coil to move up and down in the magnetic ring, thus changing the value of the inductance. The change in inductance will generate a corresponding electrical signal, which is proportional to the water level. The electrical signal is transmitted to the washing machine's microcontroller. The microcontroller determines whether the water level has reached the preset level based on the strength of the signal. Once the preset water level is reached, the microcontroller will send an instruction to control the water inlet valve to close and stop water inlet.

[0003] When the existing washing machine water level sensor is installed in washing machines of different models, the positioning structure will change. Therefore, the washing machine water level sensor needs to be set in different installation positions to adapt to different models. If the washing machine water level sensor cannot be installed reliably, it will become loose due to the vibration generated when the washing machine is working, affecting the use of the washing machine water level sensor.
