As shown in fig. 5, a nozzle body is disposed between the inlet valve 510 and the washing tub 520, and the inlet valve 510 and the washing tub 520 are centrally connected by the nozzle body.

Preferably, the air supply device 540 is an air pump.

The specific embodiment is as follows:

as shown in figures 5 to 7 of the drawings,

the washing machine includes a water inlet valve 510, a shower head body, a washing tub 520 (specifically, an inner tub, for example), a micro bubble generating device 530, a gas supply device 540, a table 550, and the like.

The gas supply unit 540 comprises an air pump, and the gas supply unit 540 is connected to the gas inlet structure 533 of the microbubble generator 530 through a gas duct 560 to supply gas to the microbubble generator 530.

The micro-bubble generating device 530 includes a spray nozzle 5301 (formed as a water outlet structure 532), a flat seal ring 5302, set screws (for locking with the mounting holes 5303), a large valve cover 5304, a large valve cover seal ring 5305, a cavity 5306 (with an inner cavity 534 formed inside the cavity), a small valve cover seal ring 5307, a small valve cover assembly 5308, a water inlet tip 53091 (formed as a water inlet structure 531), an air inlet tip 53092 (formed as an air inlet structure 533), and the like.

The water enters the cavity 5306 from the water inlet tip 53091 on the large valve cover 5304, is compressed in the cavity and then is discharged from the spray nozzle 5301. When the device is designed, the water inlet amount of the water inlet sharp nozzle 53091 is higher than the water outlet amount of the spray nozzle 5301 in unit time, so that high pressure is formed in the sealed cavity 5306, air is dissolved in water under the action of the pressure, the spray nozzle 5301 is a cavitation device manufactured by utilizing the venturi effect, and after water containing high-concentration air solute enters the spray nozzle 5301, the water is manufactured into micro-bubble discharge through the cavitation effect of the spray nozzle 5301.

After the continuous operation is performed for a period of time, the amount of water stored in the cavity 5306 is large, and the occupied space is large, so that when the cavity 5306 discharges water, micro-bubbles in the cavity 5306 are broken and disappear. Therefore, the air supply device 540 is utilized in the scheme, the water inlet pause at the water inlet tip 53091 is controlled logically, the air supply device 540 blows air into the cavity 5306 through the air inlet tip 53092 on the small valve cover component 5308, the part of water with low micro-bubble content stored in the cavity 5306 is discharged, a new period is started, and the water enters the cavity 5306 through the water inlet tip 53091 again to regenerate the micro-bubble water.

Preferably, the cavity 5306 is substantially elongated and flat to facilitate assembly of the product and compact placement within the washing machine.

In addition, the present embodiment is provided with a control device of the washing machine, and implements the control logic of the following washing machine by the control device:

first step (see step 302 in fig. 3): when washing starts, external water flows through the water inlet valve and the spray head body and enters the washing barrel, if the target water level is n, the washing barrel in the step feeds water to (n-d), n and d are constants, the value range of n is 1-8, the value range of d is 0-7, and n is larger than d.

Second step (see step 304 in fig. 3): the micro-bubble generating device changes water flow into micro-bubble water dissolved with air solute, and then the micro-bubble water passes through a detergent chamber and a softener chamber of the spray head body and enters the washing barrel. Namely the water inflow of the target micro-bubble is d grade.

A third step (see steps 306 to 312 in fig. 3): when the total water inflow time of the micro bubbles exceeds e seconds (second preset time length), the water inlet valve stops supplying water to the micro bubble generating device, namely micro bubble water is stopped from being fed into the washing barrel, the conventional water flow directly enters the washing barrel through the water inlet valve and the spray head body until the total water amount in the washing barrel reaches n grades, and then the washing barrel starts washing action. And if the total water inlet time of the micro-bubbles does not exceed e seconds, and the total water amount in the washing barrel reaches n grades, starting the washing action of the washing barrel, wherein e is a constant and has a value range of 60 seconds to 300 seconds, and the preferred value is 180 seconds. (the process aims at ensuring that the working water pressure of the washing machine is 0.03-1 Mpa, the water pressure is lower than 0.03Mpa in a special working environment, the water flow is small, the total water inlet time is abnormal and larger, meanwhile, low-pressure water flow cannot generate dense micro bubbles after passing through a micro bubble generating device, the water outlet of the device is slow, and therefore, after the total water inlet time is abnormal, water is not fed by the micro bubble generating device in the process, and conventional water is directly fed to a preset water level n grade.)

A fourth step (see step 314 in fig. 3): the air pump operates for a seconds (first preset time duration), and the stored water in the micro-bubble generating device is emptied, so that micro-bubbles can be generated by the micro-bubble generating device next time.

A fifth step (see steps 316 to 320 in fig. 3): the first step to the third step are repeated in the rinsing water inlet process, after the rinsing water inlet is finished, the air pump works for a seconds again, and the stored water in the micro-bubble generating device is emptied, so that micro-bubbles can be generated by the micro-bubble generating device next time.

Sixth step (see step 322 in fig. 3): the dewatering action is started.

The seventh step: and (6) ending.

In the fourth step, the air pump is operated for a second, the flow rate of the air pump is b milliliters/second, the cavity capacity of the microbubble generator is m milliliters, a, b and m are constants, the value range of a is 10 seconds to 60 seconds, and the preferred value is 30 seconds; b ranges from 10 ml/s to 40 ml/s, and the preferred value is 20 ml/s; m ranges from 200 ml to 800 ml, preferably 500 ml. And a, b and m satisfy the relation: a is not less than m is not less than 1.15. This kind of design can guarantee that the air pump is with the complete evacuation of residual water in the microbubble generating device.

In addition, the spray nozzle on the microbubble generating device is connected with the spray head body through a pipeline, and in the spatial layout, the height of the spray nozzle is 5-15 mm higher than the corresponding interface (inlet of the spray head body) on the spray head body, and the layout can make full use of the gravity action to discharge stored water.

And the water inlet step is realized by that the normal water enters the (n-d) gear firstly and then the micro-bubble water enters the d gear, after the process is finished, the washing or rinsing action is started, and then the air pump starts to act to perform the air supply step, so that the phenomenon that the water inlet action and the air pump work simultaneously, and the noise generated by the air pump influences the feeling of a user is avoided.
