Problems solved by technology

[0007] However, because the flocculant is directly put into the water tank of the washing machine to treat the washing water, it will cause secondary pollution of the clothes by the flocculant
In addition, if the dosage of flocculant has a large deviation, the flocculation effect will deteriorate. When the amount is small, the floc particles are small and cannot be effectively stratified, and when the amount is too large, the floc density is large and cannot be effectively stratified. Both situations will make The filter screen of the filter container is severely clogged, cannot be drained normally, and is difficult to clean. The final result is that the process of flocculation treatment of water cannot be carried out normally.

Embodiment 1

[0040] Such as figure 1 As shown, the washing is completed, and the measured turbidity value of the washing water is recorded as N1. The turbidity value N1 can be detected when it is in the bucket before it is discharged into the flocculation container, or it can be discharged into the flocculation container before the flocculant is put in. For detection, this embodiment uses the washing water to detect the turbidity value when it is not discharged into the flocculation container and is still in the water bucket. In this way, if the detected turbidity value is high, it can be directly discharged when it is not suitable for flocculation, and the flocculation treatment water is not used; omitted The step of entering the flocculation container is eliminated, which not only saves time but also prevents the flocculation container from being polluted by washing water and needs to be cleaned.

[0041]According to the detected turbidity value N1, determine the initial flocculant dosag...

Embodiment 2

[0045] This embodiment makes improvements for the color fading of the clothes: when the clothes are fading, the detected turbidity value is high, and the main control board can no longer judge whether the clothes are rinsed clean, so it cannot make a correct judgment. Therefore, the turbidity value before and after the flocculation treatment can be compared. When the difference between the turbidity value before and after the treatment is less than 20, it is considered that the turbidity value is caused by color fading, and the clothes have been rinsed and entered the dehydration process.

Embodiment 3

[0047] Such as figure 2 and image 3 As shown, the washing machine of the present invention includes a washing machine body 1 and a water circulation treatment system 2. The washing machine body 1 needs to have various parts of an ordinary washing machine, including a washing bucket 3, a main control board for controlling washing, and an automatic detergent injection device. (not shown in the figure), the tub 3 is provided with a tub turbidity detection device 4, which has a weighing or similar function to determine the amount of laundry, and a water level sensor or similar function to determine the amount of laundry water. The water circulation treatment system 2 includes a flocculation container 5 for flocculation treatment of laundry water with a flocculant, and the flocculation container 5 is provided with a flocculation turbidity detection device 6 . Further, it may also include a filter container 7 for filtering the flocculation treatment water, as well as structures s...

Abstract

The invention discloses a method for controlling flocculation processing water of a washing machine through turbidity measurement and the washing machine. The washing machine comprises a washing machine body and a water circulation processing system, wherein the water circulation processing system comprises a flocculation container used for performing flocculation processing on water discharged from the washing machine body; the flocculation container is provided with a turbidity detection device; whether the set condition is met or not is judged through detecting the turbidity of the water after the flocculation through flocculation agent putting in each time; and if the condition is not met, a measure of putting the set quantity of flocculation agents for realizing the flocculation processing on the water in different times is adopted until the set condition is met. The method of measuring the turbidity value is used for judging the putting of the flocculation agents; the method is simple; the putting quantity of the flocculation agents is precise; the defect of poor flocculation effect or even failure due to great error is avoided; the water circulation processing efficiency is improved; and the rinsing water is saved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a circulating water-saving washing machine, in particular to a method for controlling washing machine flocculation treatment water through turbidity measurement 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 consume a lot of water resources, even if it is a water-saving drum washing machine. Clothes also need to be rinsed at least twice, and this process consumes at least 30L of tap water. Sometimes there are less stains on the clothes or le...
