Embodiment 1

[0072] Such as figure 1 As shown, in this embodiment, the air intake device 9 is composed of a frequency conversion air pump 91 driven by a frequency conversion motor, and the frequency conversion air pump 91 can blow air into the flocculation container 7 at different intake rates by changing the power of the frequency conversion motor.

[0073] The control method of washing machine in the present embodiment is specifically as follows:

[0074] 10) The washing water in the water tank flows into the flocculation container;

[0075] 11) Separation stage: The frequency conversion motor of the frequency conversion air pump works at high power for a certain period of time t1 to generate a relatively high-speed air flow V1, and blow the high-speed air flow V1 into the flocculation container, and use the detergent in the washing water to generate a large amount of air in the flocculation container. Foam, the foam separates most of the dirt in the wash water from the water and wraps ...

Embodiment 2

[0083] In this embodiment, the air intake device is an air pump group composed of at least two parallel air pumps; each air pump is connected in parallel with the flocculation container, and each air pump is provided with a control device for controlling its switch, so that each air pump Or work at the same time, so that the air intake device formed by the air pump group blows air into the flocculation container at different air intake rates.

[0084] Such as figure 2 As shown, in this embodiment, the air intake device 9 is an air pump group composed of a first air pump 92 and a second air pump 93 connected in parallel. The first air pump 92 and the second air pump 93 are respectively provided with control devices for controlling their switches, so that the first air pump 92 and the second air pump 93 can work separately or simultaneously, so that the air intake device composed of the air pump group can Air is blown into the flocculation container 7 at different air intake r...

Embodiment 3

[0093] Such as image 3 As shown, in the embodiment of the present invention, the circulating water treatment device of the washing machine can also include a filter unit 23, including a filter container 231 and a filter screen 232 arranged in the filter container 231, and the filter container 231 is connected with the flocculation container 7 and the filter container 232 respectively. The water holding cylinder 2 is connected, and the water treated by flocculation in the flocculation container is filtered and re-discharged into the water holding cylinder for reuse during rinsing.

[0094] Further, the filter 232 divides the inside of the filter container 231 into two parts, the first part communicates with the flocculation container 7 through a connecting pipe, and the second part communicates with the water tank through the second circulation pipeline provided with the second drainage pump 6 2 connected.

Abstract

The invention discloses a washing machine and a control method thereof. The washing machine comprises a water containing drum, a washing structure arranged in the water containing drum and a circulating water treatment device arranged outside the water containing drum. The circulating water treatment device comprises a flocculation treatment unit and is characterized in that the flocculation treatment unit comprises a flocculation container used for flocculating water drained by the water containing drum, a flocculant throwing device for throwing flocculant into the flocculation container and an air feed device for blowing air into the flocculation container. The air feed device is provided with at least two gears with different air feeding speeds, and before the flocculant is thrown, the air feed device blows air into water in the flocculation container at high air feeding speed to generate foam; after the flocculant is thrown into the flocculation container, the air feed device blows air into the flocculation container at low air feeding speed to accelerate a flocculation reaction. By controlling the work state of the air feed device, the high-speed air is blown in the early stage, a great deal of dirt in the washing water is taken away by the foam, the consumption of the flocculant is reduced, and the efficiency of the flocculation reaction is improved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a cycle water-saving washing machine, especially a washing machine and a control method thereof. 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 less detergent is put in, and it may be rinsed clean twice, but because the user chooses 3 ...
