Problems solved by technology
[0007] This detection method is limited by the minimum water level, so it cannot detect the water volume more accurately, and the water injection volume is calculated by time, and the water volume is affected by the water pressure factor
At the same time, when water and clothes are put into the bucket, the weight of water and clothes cannot be distinguished, and the weight of water can only be calculated as the weight of clothes, which directly affects the water volume of the washing bucket

A method for detecting and determining clothes weight in the washing machine and water quantity is characterized by that on the floor supporting legs of washing machine or belbween connected places of lower end of washing cylinder and lower end of hanger rod or between the hanging corners of washing machine shell body and hanger rod, a number of weight sensors is respectively mounted for detecting the weight data of clothes and / or water in the washing cylinder. Under the condition of that in the washing cylinder, the "water-level-frequency" sensor can be used for measuring water level data, the said data can be imput into computer, then the measured weight data and / or water level can be compared with "water level-frequency", "water quantity-water level" and "clothes quantity and water quantity" relationships built-in computer by means of computer so as to analyze and judge water-injection quantity and attain the goal of saving water and savint energy.
Description
technical field [0001] The invention relates to a method for detecting and determining the amount of cloth and water in a washing machine, in particular to a method for detecting and determining the amount of cloth and water in a washing machine by using a weight sensor. Background technique [0002] At present, the basic structure of the traditional washing machine is: the bottom corners of the casing are respectively equipped with supporting feet, the outer tub is suspended on the top of the casing by 4 suspension rods, and an air chamber is arranged at the lower part of the outer tub, and the upper part of the air chamber is connected with the hose by a hose. The water level frequency sensor is connected, the center position of the bottom of the outer tub is fixed by the shaft of the clutch, the pulsator at the bottom of the inner tub is fixed on the shaft of the clutch, the drain valve and the drain hose are installed at the bottom of the outer tub, the motor is fixed at ...
