Embodiment 1

[0029] like figure 1 As shown, the washing machine of the present invention mainly includes: a box body 1 , an outer cylinder 2 , an inner cylinder 3 , a water inlet system 4 , a computer board controller 5 , a drainage system 7 , a circulating water purification device 8 , and a motor drive device 9 . The water inlet system 4 includes: a first water inlet valve 41, a second water inlet valve 42, a third water inlet valve 43, a first water inlet pipe 44, a second water inlet pipe 45, a third water inlet pipe 46, a detergent Box 47 and fourth water inlet pipe 48. The first water inlet valve 41 communicates with the detergent box 47 through the first water inlet pipe 44, and the detergent box 47 communicates with the outer cylinder 2 through the fourth water inlet pipe 48, which is a pre-water inlet passage for washing water. The second water inlet valve 42 is communicated with the detergent box 47 through the second water inlet pipe 45, and the detergent box 47 is communicated...

Embodiment 2

[0038] The difference between this embodiment and the first embodiment is that the washing machine is also provided with a second turbidity threshold. After washing, the turbidity detection device 10 is activated to detect the turbidity voltage signal V1 of the washing water, and calculate the turbidity according to V0, V1 and the turbidity formula. The wash water turbidity value NTUa at this time was calculated. Determine whether NTUa is less than the set first turbidity threshold NTU1 (for example, 600NTU). If so, it indicates that the turbidity of the washing water is not high, and it is suitable for direct circulation purification. If not, further judge whether NTUa is greater than the set second turbidity. Threshold NTU2 (for example, 900NTU), NTU1 < NTU2, if it is, it indicates that the turbidity of the washing water is too high and it is not suitable for circulating purification, and the water is directly drained and re-entered with clean water to perform circulating cle...

Embodiment 3

[0041] The difference between this embodiment and the first embodiment is that the washing machine does not have a first turbidity threshold, and the set ratio n of the discharged water to the total washing water, 0≤n≤1, the first turbidity threshold set in the first embodiment The turbidity threshold NTU1 or less is set to the interval corresponding to the drainage ratio of 0 in this embodiment, and the second turbidity threshold NTU2 or higher set in the first embodiment is set to the interval corresponding to the drainage ratio of 1 in this embodiment. The corresponding relationship between the set turbidity interval and the drainage ratio n is:

[0042] Turbidity interval (NTU)

[0043] Therefore, in this embodiment, after washing, it is only necessary to determine the corresponding above-mentioned interval according to the detected turbidity NTUa of the washing water, and execute the next step.

Abstract

The invention discloses a washing machine cycle cleaning control method and the washing machine. The washing machine includes a water tank, a water inlet system, a drainage system, a cycle water purification device and a turbidity detection device, and also includes a cycle water purification path and backwash cleaning The passage, the circulating water purification passage is composed of the water tank, the drainage system, the circulating water purification device, the water inlet system and then the circulation passage of the water storage tank, and the backwash cleaning passage is composed of the water inlet system, the circulating water purification device and the drainage system. In the rinsing process, the washing machine of the present invention executes the circulating clean water rinsing through the circulating water purifying device, and according to the turbidity of the washing water detected by the turbidity detecting device, selects the preset displacement corresponding to the turbidity and then enters the clear water to reduce the turbidity Afterwards, perform a rinsing cycle with clean water. In the present invention, the scheme of reducing the turbidity by discharging part of the water and then entering clean water is more time-saving than purifying all the washing water with high turbidity, so as to achieve the purpose of stopping immediately after washing and saving water, time and electricity.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine for purifying water circulating and rinsing, in particular to a washing control method for washing with purifying water in a washing machine cycle and a washing machine thereof. Background technique [0002] With the improvement of people's living standards, washing machines have now become one of the main household appliances in people's daily life. The laundry process of the washing machine mainly includes several stages of washing, rinsing, and drying. During the washing stage, the washing machine enters water and detergent to wash the clothes. , after entering the rinsing stage, in order to rinse 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, even for a water-saving front-loading washing machine, in order to Rinse clothes also ne...
