Embodiment 1

[0036] Embodiment 1. In this embodiment, a conductivity detection method is used to obtain the concentration level of detergent.

[0037] The concentration of detergent is reflected by the content of its active substances. Currently, there are two main methods for detecting the content of such active substances: optical sensor detection method and chemical reagent detection method. Among them, the optical sensor detection method has a high sensor cost and a complicated structure. If it is applied to a washing machine, it will not only complicate the hardware structure design of the washing machine, but also significantly increase the cost of the washing machine. However, the chemical reagent detection method requires offline detection, consumes reagents, and cannot achieve concentration distinction online, so it is not suitable for application in washing machine products.

[0038] In order to meet the application requirements of the washing machine, this embodiment uses the co...

Embodiment 2

[0096] In the second embodiment, the detergent concentration level is obtained by manually inputting detergent concentration parameters.

[0097] see Figure 5 , Image 6 In this embodiment, a detergent box 22, an automatic feeding device 25, a weight detection device 27, a man-machine interface 29 and a control module 28 are provided in the washing machine. Wherein, the detergent box 22 is used for storing a certain capacity of detergent 23, and its storage capacity can meet the demand of detergent dosage for multiple washing procedures. An automatic dispensing device 25 is installed on the detergent box 22 for quantitatively extracting and dispensing the detergent 23 stored in the detergent box 22 . Similarly, the automatic delivery device 25 can also be designed in various ways such as Venturi tube negative pressure quantitative extraction mode, quantitative pump automatic extraction mode, and the like. The detergent 23 quantitatively extracted by the automatic dispensin...

Abstract

The invention discloses a precise detergent dosage control method and a washing machine. The method comprises steps that N concentration intervals are established in order from low to high; each concentration interval is assigned with a concentration level, the i-th concentration interval corresponds to the i-th concentration level, Ci=N-i+1, and i=1,... ..., and N; the concentration level Ci of the detergent in a washing apparatus is determined; the weight m of the laundry is obtained; a formula Vn=1.25*m* (Ci + 1) is utilized, and the dosage Vn of the detergent is obtained through calculation. The method is advantaged in that two factors of detergent concentration and washing clothes weight are comprehensively considered, the detergent dosage is determined through formula calculation, soprecise control of the detergent dosage is realized, a problem that the concentrated detergent is excessively applied when the detergent dosage is determined based on the weight of the laundry is solved, and problems of detergent residue, increased foams, multiple rinsing and water and electricity waste due to excessive detergent delivery are solved.

Description

technical field [0001] The invention belongs to the technical field of washing equipment, and in particular relates to a method and a washing machine capable of automatically controlling the amount of detergent according to the concentration of the detergent. Background technique [0002] Washing machine is a kind of special cleaning equipment used for washing clothes, cotton, linen, chemical fiber and other textiles. The current washing machine, whether it is a fully automatic washing machine or a semi-automatic washing machine, basically has the three basic functions of washing, rinsing and dehydration. To a certain extent, it reduces people's labor intensity and makes people's lives comfortable. Moreover, with the development of society, people's requirements for quality of life are gradually improving and expectations for smart products are constantly improving, and washing machines are also developing rapidly in the direction of intelligence. [0003] Most of the curre...
