US 11,236,454 B2 · Method for controlling release amount of detergent, and washing machine

Abstract

A method for controlling release amount of detergent and a washing device, include: dividing inner space of a detergent box into independent N compartments, wherein each of the compartments is configured to store a type of detergent having a certain concentration range; assigning a concentration level Ci, i=1, . . . , N to each of the compartments wherein the higher the detergent concentration, the lower the concentration level; selecting one of the compartments containing detergent and releasing the detergent in the selected compartment, and obtaining the concentration level C of the selected compartment; obtaining a laundry weight m; and calculating a release amount of the detergent, wherein Vn=1.25*m*(C+1). The formula which is configured to calculate the release amount of detergent is also provided based on both of the detergent concentration level and the laundry weight. Hence, the problem of excess foaming and residue caused by putting too much concentrated detergents which have to introduce more rinsing cycles could be effectively solved.

A washing machine comprising:

a detergent box configured to store detergent is divided into independent N compartments, wherein each of the compartments is configured to store a type of detergent having a certain concentration range;
an automatic dispensing device configured to draw a certain amount of detergent from the detergent box to dispense;
N solenoid valve(s), wherein one of the solenoid valve is configured to selectively communicate one compartment with the automatic dispensing device;
a weight detecting device configured to detect the weight of the laundry in the washing machine;
and
a control module storing concentration levels Ci, i=1, . . . , N which corresponds to the independent N compartments wherein the higher the detergent concentration, the lower the concentration level;
as running washing program, the control module configured to drive one of the solenoid valve to open and obtain the concentration level C of the selected compartment, and to receive the laundry weight m input from the weight detecting device and calculate a release amount of detergent Vn, Vn=1.25 * m * (C+1), and to control the automatic dispensing device to draw corresponding amount of detergent to dispense.
