Liquid quantity detection method, device, system and household electrical appliance

Abstract

The invention relates to a liquid quantity detection method, a liquid quantity detection device, a liquid quantity detection system and a household electrical appliance. According to the liquid quantity detection method, the liquid quantity detection device, the liquid quantity detection system and the household electrical appliance of the invention, capacitance acquisition is carried out through each capacitance detector arranged on a liquid container; when a liquid quantity in the liquid container changes, the change of the liquid quantity can be sensed by the capacitance detectors, and corresponding capacitance value collection can be carried out; when the capacitance detectors acquire capacitance values, the sum of the corresponding capacitance values is obtained through calculation; and analysis is performed on the sum of the capacitance values and a preset fitted curve, so that liquid level data in the liquid container can be obtained directly. According to the liquid quantity detection method, the liquid quantity detection device, the liquid quantity detection system and the household electrical appliance provided by the technical schemes of the invention, complex data are linearized according to the preset fitted curve; a large quantity of data do not need to be stored during liquid quantity detection, and therefore, the consumption of storage resources is reduced, and operation speed is effectively increased; liquid quantity detection is linearized, so that the minimum scale of the liquid level data obtained by final detection can reach 1% or even can be smaller, and therefore, the resolution and precision of liquid quantity detection are effectively improved. The method has the advantage of high detection reliability and the like.

Description

technical field [0001] The present application relates to the technical field of detection, in particular to a liquid volume detection method, device, system and household appliances. Background technique [0002] With the rapid development of science and technology, the types of household appliances are becoming more and more diverse. An electric steamer is a cooking utensil that uses dynamic steam balance technology to achieve food cooking. It uses a liquid container (ie a water tank) for water supply, and the amount of water will gradually decrease during use. If the amount of water in the water tank is not enough during use, it may cause the steamed food to be too dry, affect the taste, and even damage the water tank. Therefore, in order to ensure the stable operation of the electric steamer, it is particularly important to detect the water level in the water tank. [0003] The traditional liquid volume detection method uses a reed switch to cooperate with a magnet in ...
