One end of the circulation line 4 is connected to the bottom of the outer tub 1, and the other end of the circulation line 4 is connected to the top of the outer tub 1. The circulation pipeline 4 and the outer barrel 1 form a circulation channel, and water in the outer barrel 1 can realize the circulation flow of the water along the circulation pipeline 4.
The position where the circulation pipeline 4 is connected to the bottom of the outer tub 1 is not particularly the bottom of the outer tub 1. The bottommost part of the outer tub 1 and the position close to the bottommost part of the outer tub 1 are both the bottom of the outer tub 1, and are within the protection scope of the present invention. Specifically, the position where the circulation pipeline 4 is connected to the bottom of the outer tub 1 in this embodiment is a position lower than the lowest washing water level on the outer tub 1, so as to ensure that the circulation pipeline 4 can still perform water circulation when washing at the lowest washing water level.
The position where the circulation line 4 is connected to the top of the outer tub 1 is not particularly the topmost part of the outer tub 1. The topmost part of the outer tub 1 and the position close to the topmost part of the outer tub 1 are both the top of the outer tub 1, and are within the protection scope of the present invention.

In order to improve the filtering effect and the filtering efficiency, the filtering means 6 of the present embodiment is a filtering membrane, and the diameter of the filtering means 6 is larger than that of the circulation line 4.
And the bubble generating device is positioned on the circulating pipeline 4 and is used for generating bubbles in the water passing through the circulating pipeline 4, namely, the bubbles are mixed in the water passing through the circulating pipeline 4 to form bubble water.

This embodiment can realize the effect of filtering impurity filth and production bubble in step in same circulating line, and the structure is simplified, and washing efficiency and rinsing efficiency improve greatly, save the water resource. Because filter equipment 6 filters the time, if aquatic impurity filth is more, filter equipment 6's the one side of intaking piles up impurity filth easily, leads to filter equipment 6's filtering quality and filtration efficiency variation. In order to solve the above problem, the present embodiment washes the filtering device 6 with water in the circulation line 4 to ensure the filtering performance and the filtering efficiency of the filtering device 6.
Specifically, the drain pipe 3 is connected to the outer tub 1, the first switch is arranged on the circulation pipeline 4 between the filtering device 6 and the bottom of the outer tub 1, the second switch is arranged between the circulation pipeline 1 between the filtering device 6 and the bottom of the outer tub 1 and the drain pipe 3, and the washing machine comprises a controller which controls the states of the first switch and the second switch.

Under the action of the water pump 5, water in the outer barrel 1 enters the circulating pipeline 4, is firstly filtered by the filtering device 6, then passes through the bubble generating device 7 to generate bubble water and enters the washing barrel through the top of the outer barrel 1, and therefore the water in the washing barrel is bubble water.
When the controller controls the washing machine to be in a flushing state, the controller controls the water pump 5 to stop working, controls the first switch of the three-way electromagnetic valve 8 to be switched off, and controls the second switch to be switched on, and controls the bubble generating device 7 to stop working.

The method for conducting the outer barrel and the circulating pipeline comprises the steps of controlling the first switch of the three-way electromagnetic valve to be conducted, and controlling the second switch to be disconnected. The water pump and the bubble generating device are controlled to work, under the action of the water pump, water in the outer barrel enters the circulating pipeline, is filtered by the filtering device at first, and then generates bubble water through the bubble generating device and enters the washing barrel through the top of the outer barrel, so that the water in the washing barrel is the bubble water, and the bubble water washes clothes.
And (3) washing the filtering device:
and the circulating pipeline is communicated with the drain pipe, and water in the circulating pipeline is discharged through the drain pipe after washing the filtering device under the action of gravity.
The method for conducting the circulating pipeline and the water drainage pipe comprises the steps of controlling a first switch of the three-way electromagnetic valve to be disconnected and controlling a second switch of the three-way electromagnetic valve to be conducted. The water pump and the bubble generating device are controlled to stop working, water in the circulating pipeline passes through the filtering device under the action of gravity, impurities and dirt in the filtering device are washed, and the impurities and the dirt are discharged through the water discharging pipe.
In this embodiment, water is always stored in the circulation line 4 during the generation of bubble water, and although the water stored in the circulation line 4 can flush the filter device 6 to a certain extent, the flush effect of this embodiment is general because the amount of water stored in the circulation line 4 is limited.
According to the dirty difference of doing washing, there can be the impurity filth deposit of different volume on filter equipment, in order to avoid filter equipment filterable impurity filth not to bring the hindrance for bubble generating device, accelerate washing efficiency and rinsing efficiency simultaneously, in this embodiment, the step of producing bubble water and the step of washing filter equipment are gone on in turn.
In the washing process, after the step of generating bubble water is carried out for time t1, a step of washing the filtering device is carried out for one time; after the step of generating bubble water during the rinsing process is performed at time t2, a step of washing the filter device is performed once. Wherein t2 > t 1.
In the rinsing stage, the impurity and dirt content in the water is gradually reduced, so that the impurity and dirt filtered by the filtering device is also gradually reduced, and frequent washing is not needed. As the number of rinses increases, the execution time of the bubble water generating step increases.
Specifically, as shown in fig. 5, a specific washing process of this embodiment:

Further, the control method of the washing machine of the present embodiment includes a step of generating bubble water and a step of washing the filtering device.
Specifically, the step of generating bubble water comprises the following steps:
the water pump enables water at the bottom of the outer barrel to flow to the top of the outer barrel through the circulating pipeline, and the water is firstly filtered by the filtering device and then forms water flow with bubbles through the bubble generating device.
The method for conducting the outer barrel and the circulating pipeline comprises the steps of controlling the first switch of the three-way electromagnetic valve to be conducted, and controlling the second switch to be disconnected. The water pump and the bubble generating device are controlled to work, under the action of the water pump, water in the outer barrel enters the circulating pipeline, is filtered by the filtering device at first, and then generates bubble water through the bubble generating device and enters the washing barrel through the top of the outer barrel, so that the water in the washing barrel is the bubble water, and the bubble water washes clothes.
