In the present embodiment, the main body 41 is provided in an L-like configuration. By arranging the main body in an L-like configuration and designing the edges in a streamline shape, the volume of the main body can be expanded while taking into account the installation problem of the microbubble generator 4.
The process of generating microbubbles by the microbubble generator 4 is as follows: running water flows through the water inlet part 42 and enters the main body 41, the water inlet end of the water outlet pipe 45 is sealed after the water level in the main body 41 rises to form sealed air, the water level further rises to compress the sealed air, the air is promoted to be dissolved in a large amount of water, under the pushing of the running water pressure, the water dissolved with a large amount of air enters the water outlet part 43 along the water outlet pipe, and because the micro-bubble generating mechanism is arranged in the water outlet part 43, the air dissolved in the water is separated out and generates a large amount of micro-bubble water. After the micro bubble generating device 4 completes a micro bubble production process, the first water inlet valve 51 is closed, a part of water remains in the first water inlet valve, in order to discharge the remaining water, the drain valve 8 is opened at this time, the remaining water flows out under the action of gravity, the remaining water can be completely discharged after the preset drainage time t, and the drain valve 8 can be closed at this time.
Since the size of the internal space of the microbubble generator main body 41 is fixed and the amount of the enclosed air is also fixed, as tap water continuously enters and forms microbubble water, the enclosed air is continuously consumed until the air is completely consumed, and microbubbles cannot be generated, so that the amount of the microbubble water generated by the microbubble generator enclosing air once is basically constant.
Meanwhile, since the amount of the residual water is fixed, the speed at which the water flows out under the gravity is also fixed, and thus the preset drainage time t is set.
For a more clear explanation of the present application, the structure and control method of the washing machine of the present application will be further explained by taking the embodiment shown in fig. 1 to 11 as an example:

The water inlet portion 42 is connected to a first water inlet valve 51 through a first pipe 61, and the other end of the first water inlet valve is connected to a tap water pipe. The water outlet part 43 is connected with the washing drum 10 through the third pipeline 7. The lowermost end of the main body 41 is provided with a drain part 44 for discharging the residual water in the main body 41, the drain part 44 is connected to the drain valve 8, and the other end of the drain valve passes through the fourth pipe 9 to wash the drum 10.
In order to adapt to different washing or rinsing modes, different washing water or rinsing water is needed to be used and can be divided into three types; all micro-bubble water, all conventional water, and micro-bubble water and conventional water mixed water respectively correspond to the first state, the second state and the third state.
Therefore, the water inlet modes of the washing machine can be divided into three types, the first water inlet mode is micro-bubble water, and the water inlet method comprises the following steps:
as shown in fig. 2, the control system of the washing machine controls the first water valve 51 to be opened, the drain valve 8 is closed, tap water enters the water inlet portion 42 of the micro-bubble generating device 4 along the first pipeline 61, and enters the main body 41 after being branched, the tap water seals air and is pressurized to promote dissolution and water in the main body 41, water with a large amount of dissolved air enters the water outlet portion 43 of the micro-bubble generating device along the water outlet pipe, a large amount of micro-bubbles are generated in the water outlet portion 43, and water containing micro-bubbles enters the washing drum 10 along the second pipeline 7.
After the water amount in the washing machine reaches the water amount of the first preset water level, it is described that the air sealed by the micro-bubble generating device 4 is basically completely consumed, the micro-bubble water cannot be continuously generated, at this time, the first water inlet valve 51 is closed, tap water stops entering the micro-bubble generating device 4, the water discharge valve 8 is opened, after time t, all residual water in the micro-bubble generating device 4 is discharged, air enters and fills the micro-bubble generating device 4, at this time, the water discharge valve 8 is closed, the first water inlet valve 51 is opened, the micro-bubble generating device 4 restarts water inlet, gas dissolving and micro-bubble generating processes, when the water amount of the first preset water level reaches 2 times, the residual water is discharged again, the micro-bubble generating process is started, and the process is circulated in such a way, and the water amount of the first preset water level reaching n times can be reached.
After the water amount in the washing machine reaches the water amount of the second preset water level, the first water inlet valve 51 is closed, the tap water stops entering the micro-bubble generating device 4, the drain valve 8 is opened, after the time t, all residual water in the micro-bubble generating device 4 is discharged, and the drain valve 8 is closed.
It should be noted that the first preset water level is defined as the amount of micro-bubble water generated by the micro-bubble generating device by enclosing the primary air, and the second preset water level is the amount of water required by the washing machine for washing or rinsing.
The second water inlet method is that the whole water is conventional water:
as shown in fig. 3, the control system of the washing machine controls the first water inlet valve 51, the second water inlet valve 52 and the drain valve 8 to be opened simultaneously, tap water enters the microbubble generator through the first pipeline 6, most of the tap water enters the washing drum 10 through the drain valve 8 and the third pipeline 9 from the drain part 44 because the drain valve 8 is in an opened state, and a small part of the tap water enters the washing drum 10 from the water outlet part 43 and the second pipeline 7, and the microbubble generator 4 cannot form a pressure maintaining dissolved air state because the lower part of the microbubble generator is in an opened state, so that microbubble water cannot be formed, and the washing machine belongs to conventional water.
