Embodiment 1

[0039] Such as figure 1 and figure 2As shown, the flocculation container 10 and the filter container 12 described in this embodiment are arranged side by side under the outer cylinder 2. A stop valve 15 is provided to control the connection / disconnection between the two containers. The upper part of the flocculation container 10 communicates with the water outlet at the bottom of the outer cylinder 2 through the water guide pipe 16, and the water guide pipe 16 is provided with a water outlet control valve 17. The bottom of the flocculation container 10 is provided with a drainage structure for draining to the outside of the washing machine, including a drainage port of the flocculation container, a drain pipe 18 and a drain valve 19 communicating with the drain port.

[0040] Further, the filter container 12 is provided with a circulating water structure for discharging filtered water into the outer cylinder 2, including a circulating water outlet of the filter container, a...

Embodiment 2

[0042] Such as image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the filter container 12 is arranged inside the flocculation container 10, the chamber between the filter container 12 and the flocculation container 10 is used for flocculation treatment water, and the lower part of the filter container 12 is provided with There is a port, and the port is provided with an on-off control structure 22 for controlling the connection / disconnection between the two containers.

Embodiment 3

[0044] Such as Figure 5 and Figure 6 As shown, the flocculation container 10 described in this embodiment is arranged above the filter container 12, the bottom of the flocculation container 10 communicates with the upper part of the filter container 12 through a connecting pipe 14, the connecting pipe 14 is provided with a stop valve 15, and the upper part of the flocculation container 10 is connected to The water outlet at the bottom of the outer cylinder 2 is communicated through the water guide pipe 16, and the water guide pipe 16 is provided with a water outlet control valve 17.

[0045] The bottom of the filter container 12 is provided with a drainage structure for draining water to the outside of the washing machine and a circulating water structure for discharging filtered water into the outer cylinder 2. The filter screen 13 divides the inside of the filter container 12 into two parts. The connecting pipe 14 communicates with the drainage structure, and the second p...

Abstract

A washing machine with a circulated water treatment function and a control method therefor. The washing machine comprises a water holding barrel (2), a washing structure arranged inside the water holding barrel (2) and a circulated water treatment device arranged under the water holding barrel (2), wherein the circulated water treatment device comprises a flocculation treatment unit and a filtering unit, the flocculation treatment unit comprises a flocculation container (10) connected to the water holding barrel (2) and a flocculation agent dosing device (11) for dosing a flocculation agent into the flocculation container (10), and water is discharged from the water holding barrel (2) to the flocculation container (10) for flocculation treatment; and the filtering unit comprises a filtering container (12) and a filter net (13) arranged inside the filtering container (12), the filtering container (12) is in communication with the flocculation container (10) and the water holding barrel (2), respectively, for filtering the water having been flocculation-treated in the flocculation container (10) and discharging same again into the water holding barrel (2) for reuse. The washing machine circularly treats water by flocculation and filtration till the end of washing, in which the water is discharged into the circulated water treatment device for purification in the flocculation treatment unit and the filtering unit and finally discharged outside. The washing machine has the advantages of saving water resources, reducing water pollution and protecting the environment.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a circulating water-saving washing machine, especially a washing machine with a circulating water treatment function 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 r...
