Embodiment 1

[0039] Such as figure 2As shown, in this embodiment, the overflow port 15 of the filter device 10 communicates with the flocculation bucket 20 through the overflow pipe 30 , so that the overflow water at the filter device 10 flows back into the flocculation bucket 20 from the overflow pipe 30 . The overflow pipe 30 is provided with a first flow sensor 16 for detecting overflow flow velocity.

[0040] In this embodiment, comparing the detected value of the first flow sensor 16 with the preset set value V1 in the system has the following conditions:

[0041] Situation 1. When the detection value of the overflow flow rate of the filter device is equal to 0, it is judged that the filter device is not blocked, and the filter device is working normally;

[0042] Situation 2: When the detection value of the overflow flow rate of the filter device is greater than 0 and less than the set value V1, it is judged that the filter device is slightly blocked, the flow rate of the water in ...

Embodiment 2

[0049] Such as image 3 As shown, in this embodiment, the water outlet 14 of the filter device 10 is provided with a second flow sensor 19 for detecting the water flow velocity.

[0050] In this embodiment, comparing the detection value of the second flow sensor 19 with the preset set value V2 in the system is as follows:

[0051] Situation 11. When the outlet flow rate of the filter device is greater than the set value V2, it is judged that the filter device is not blocked, and the filter device works normally;

[0052] Situation 12: Within a certain period of time t, the detected value of the water outlet flow rate of the filter device is always lower than the set value V2, and it is judged that the filter device is blocked.

[0053] Preferably, in this embodiment, in case 12, it is judged that the filter device is slightly clogged, the flow rate of water entering the filter device decreases, and a prompt signal is sent out that the filter device needs to clean the filter e...

Embodiment 3

[0057] Such as figure 1 and Figure 4 As shown, in this embodiment, the flocculation bucket 20 is provided with a water level sensor 21 for detecting the height of the water level inside it.

[0058] In this embodiment, the detection value of the water level sensor 21 is compared with the preset set value h in the system as follows:

[0059] Situation 21. When the outlet flow rate of the filter device is greater than the set value V2, it is judged that the filter device is not blocked, and the filter device is working normally;

[0060] Situation 22. Within a certain period of time t, the water level drop of the flocculation water in the flocculation bucket is less than the set value h, and it is judged that the filter device is blocked.

[0061] Preferably, in this embodiment, in case 22, it is judged that the filter device is severely blocked, the water supply to the filter device is stopped, and a prompt signal is issued to indicate that the filter element needs to be rep...

Abstract

The invention discloses a flocculation washing machine which comprises an outer barrel, a washing structure and a circulation water treatment device, wherein the washing structure is arranged inside the outer barrel; the circulation water treatment device is arranged outside the outer barrel; the circulation water treatment device comprises a flocculation treatment unit for performing flocculation treatment on washing water; the flocculation treatment unit is connected with the outer barrel through a filtering device, and flocculation water flows back to the outer barrel after filtration treatment; an overflowing hole is formed in the filtering device; a flow sensor for detecting overflowing velocity is arranged at the overflowing hole. The invention further relates to a control method of the washing machine. The control method comprises the following steps: performing real-time detection on the overflowing velocity of the filtering device and / or the liquid level height of a flocculation barrel, and judging the blocking situation of the filtering device according to the relationship of a detection value and a set value. The blocking situation of the filtering device is confirmed by judging whether the overflowing velocity of the filtering device and / or the liquid level height reduction velocity of the flocculation barrel are greater than set values or not, and the purpose that whether a filter element of the filtering device needs to be cleaned or replaced is precisely judged can be achieved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a flocculation washing machine with a cycle water-saving function, and also relates to a control method of the above-mentioned flocculation 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 less detergent is put in, and i...
