Embodiment 1

[0048] In the washing machine water intake control method provided in this embodiment, the washing machine is preset with a standard washing water level corresponding to the weight of the clothes. After detecting the degree of turbidity, the amount of washing water corresponding to the degree of turbidity is fed to the first washing water level. The first washing The water level is lower than or equal to the standard washing water level. The above-mentioned second water intake reaches the washing water level, which is the first washing water level corresponding to the degree of dirtiness obtained according to the detected degree of dirtiness, and is also the actual washing water level of the final laundry in the inner tub.

[0049] The first washing water level is preset according to the different turbidity values. Different turbidity values ​​correspond to different first washing water volumes. The first washing water volume is inversely proportional to the turbidity value. Th...

Embodiment 2

[0051] This embodiment is optimized on the basis of Embodiment 1, wherein the second water intake reaches the washing water level, and the washing water level is the first washing water level corresponding to the degree of pollution obtained according to the degree of pollution detected, which is also the final washing water level in the inner tub. The actual washing water level of the clothes. N turbidity value intervals are preset for the turbidity degree, and the turbidity value intervals correspond to different first washing water volumes.

[0052] Here, take the third level of laundry volume as an example, and the standard washing water level is 35L. Three intervals of the degree of contamination are preset for the degree of contamination, and it is judged which interval the detected value of the degree of contamination falls into, so as to determine the amount of first washing water for the second water inflow corresponding to the interval.

[0053] Such as figure 2 A...

Embodiment 3

[0056] Such as figure 1 As shown, the washing machine water intake control method provided in this embodiment, the steps include:

[0057] Step S101, add detergent, weigh the clothes, and determine the corresponding initial water level; after the clothes are put into the washing tub before entering the water for the first time, the washing tub rotates for a period of time, and the current weight of the clothes is determined by the relevant parameters of the motor, according to the weight of the clothes The weight presets the initial water level. Or calculate the weight of the clothes according to the weighing of the load cell.

[0058] Step S102, enter water and detect the water level; the method for controlling the water intake of the washing machine according to the present invention can use a water level sensor to measure the water level, wherein the sensor can be a traditional external water level sensor or a built-in water level sensor, and the sensor can be an inductor ...

Abstract

The invention provides a washing machine water intake control method and a washing machine, which detect and judge the degree of turbidity. The greater the degree of turbidity, the smaller the water intake. Detect and judge the degree of turbidity. When the degree of turbidity is high, reduce the amount of water inflow, thereby increasing the concentration of detergent to achieve the cleaning effect. It solves the need to increase the dosage of detergent in order to achieve the cleaning effect when the clothes are highly dirty. The amount of washing will prolong the washing time, causing energy waste and low washing efficiency.

Description

technical field [0001] The invention relates to the technical field of laundry, in particular to a washing machine water intake control method and the washing machine. Background technique [0002] With the improvement of people's living standards, the washing machine has become one of the main household appliances in people's daily life. The washing process of the washing machine mainly includes several stages of washing, rinsing and drying. , after entering the rinsing stage, in order to rinse off the stains and residual detergent, it is necessary to enter more water or perform more rinsing times to rinse the clothes, which will inevitably consume a lot of water resources, how to do it while washing the clothes To save water and save detergent, it has always been one of the focuses of consumers. [0003] The existing washing machine, taking the drum as an example, puts the laundry into the washing machine and starts the washing process. Most of the washing machine water i...
