Embodiment 1

[0029] Such as figure 1 As shown, the washing machine of the present invention mainly includes: a casing 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, detergent Box 47 and the 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-inlet channel for washing water. The second water inlet valve 42 communicates with the detergent box 47 through the second water inlet pipe 45 , and the detergent box 47 communicates with the oute...

Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 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 washing water turbidity voltage signal V1, and according to V0, V1 and the turbidity calculation formula Calculate the wash water turbidity value NTUa at this time. 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 determine 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 circular purification, and it is directly drained and re-introduced into clean water to perform circular clean water rinsing; otherwise, it is judge...

Embodiment 3

[0041] The difference between this embodiment and Embodiment 1 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 is 0≤n≤1. The first turbidity threshold set in Embodiment 1 The turbidity threshold NTU1 is set as the interval corresponding to the drainage ratio of 0 in this embodiment, and the second turbidity threshold NTU2 set in the first embodiment is set as 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 interval according to the detected wash water turbidity NTUa, and perform the next step.

Abstract

A washing control method for circular water purification of a washing machine and a washing machine. The washing machine comprises an outer drum (2), a water supplying system (4), a water discharging system (7), a circular water purifier (8), and a turbidity detector (10). The washing machine further comprises a circular water purification passage and a backflushing passage. The circular water purification passage is formed by a circulation passage from, in turn, the outer drum (2), the water discharging system (7), the circular water purifier (8), and the water supplying system (4) to a water receiving drum. The backflushing passage is formed by a passage from the water supplying system (4), the circular water purifier (8) to the water discharging system (7). The washing machine performs circular water purification rinsing by using the circular water purifier (8) during rinsing, selects, according to the turbidity of washing water detected by the turbidity detector (10), a preset amount of drainage corresponding to the turbidity for drainage, and then supplies clean water, so as to reduce the turbidity and then perform the circular water purification rinsing. Drainage of a part of water and supply of clean water to reduce the turbidity save more time as compared with purification of all washing water having high turbidity, so as to achieve the objectives of stopping when clothes are clean and saving water, time, and energy.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine for circulating and rinsing with purified water, in particular to a washing control method for circulating and purifying water of a washing machine 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 ...
