Embodiment 1

[0039] Embodiment 1: the current container size of detergent is: the bottom area is 20*13.2=264 square centimeters; the height is 7.6 centimeters, so the volume is 264*7.6=2006.4 cubic centimeters=2.0064 liters, when the container is full The volume of the detergent is the volume of the detergent, so the volume of the current detergent is 2.0064 liters. According to the value measured by the weight sensor, the density of the current detergent can be obtained by using ρ=m / v. According to the predetermined corresponding relationship between density and concentration, Determine the concentration of the current detergent and select the corresponding dosage.

Embodiment 2

[0040] Embodiment 2: the size of the detergent container is: the bottom area is 10*10=100 square centimeters, the height is 10 centimeters, and the current volume is 100*10=1000 cubic centimeters=1 liter. The volume is the volume of the detergent, so the volume of the current detergent is 1 liter. According to the value measured by the weight sensor, the density of the current detergent can be obtained by using ρ=m / v. According to the predetermined correspondence between density and concentration, judge Display the concentration of the current detergent and select the corresponding dosage.

Abstract

The invention discloses a method for automatically determining the adding amount of a detergent according to the detergent concentration of a washing machine, which relates to the field of home appliances. The method comprises the following steps of: 1, obtaining the basal area of a detergent-accommodating vessel; 2, obtaining the height of the detergent in the vessel; 3, obtaining the weight of detergent in the vessel; 4, calculating the volume of the current detergent according to the basal area and the height; 5, calculating the density of current detergent according to the volume and the weight of the detergent; and 6, comparing the density with set data in a database by using a master control program to obtain the concentration of the current detergent and then controlling the opening size and time of a delivery valve according to the comparison result. By the method, the concentration of different detergents are discriminated and the throwing amount is automatically adjusted according to the corresponding set program, so the washing effect is improved and the waste of the detergent is reduced; and the particular concentration of the current detergent can be obtained by using a plurality of sensors, so complicated manual operation is reduced and intellectualization and high efficiency are expected to be realized.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a method for automatically controlling the dosage of detergent according to the detergent density of a washing machine. Background technique [0002] At present, with the development of the home appliance industry, each home appliance is tapping its own development potential, and many additional functions and original functions of each home appliance have been greatly strengthened and improved. In the washing machine industry, it is a popular function for the washing machine to automatically inject detergent during the washing process. This solution generally installs a storage container / chamber inside the washing machine, which is usually filled with detergent. During the washing process, the washing machine controls the injection valve. The flow rate of the detergent is controlled to control the time, frequency and milliliters of the detergent. The program and equipment structure...
