Description
Technical Field

Background
A washing machine is a device for washing relatively dirty laundry contained in the washing machine by using a detergent and a mechanical rotation action. With the improvement of living standard of people, a washing machine is one of main household appliances of daily life, the washing process of the washing machine mainly comprises several stages of washing, washing dehydration, rinsing and rinsing dehydration, the washing stage comprises washing water inflow of the washing machine and washing of washings by detergent, the rinsing stage comprises rinsing water inflow of the washing machine, the part of the inflow water mainly aims at removing the detergent remained on the washings, and multiple times of rinsing are needed in the rinsing process, so that a large amount of water resources are consumed, how to save water while washing clothes is achieved, and the washing machine is one of focuses of attention of consumers.
At present, one of the reasons influencing the washing performance of the washing machine is the water inflow, the water inflow is closely related to the liquid level height, and the washing machine mainly controls the water inflow to determine the liquid level height. The liquid level height is detected by a frequency type water level sensor generally, and the working principle of the frequency type water level sensor is that air in an air chamber inside the water level sensor is compressed due to the change of the liquid level height, a magnetic core inside an inductor is pushed to generate displacement, so that the inductance value is changed, and then an external LC oscillator generates a frequency which changes along with the liquid level difference. The existing control method for water inlet of washing machine is an absolute liquid level control method, i.e. the optimum washing liquid level height is predetermined, and the frequency value corresponding to the liquid level height is obtained, when the water level frequency value detected by water level sensor is the set frequency value, the water inlet is stopped, and the washing is carried out. However, because the manufacturers of the water level sensors are different, the oscillation circuits are different, the measurement accuracy of the computer board is high, the assembly difference of the whole washing machine is different, and the like, when the water level sensors of different washing machines detect the same water level frequency, the difference of the water inflow is large, the accurate control of the water inflow is greatly influenced, and the water consumption difference of the washing machine is large. And the reference water level may drift due to external environmental factors, so that the water inflow amount is not the optimal amount of washing water, thereby causing adverse effects on the washing effect.
