However, the washing machine usually has only a single washing chamber with a large volume, and even at the lowest water level, the required water amount is large, and for single-piece and small-size clothes, water resources and electric power resources are obviously wasted excessively. And because of a single washing cavity, clothes with different colors and types need to be washed in different batches in order to avoid cross contamination or damage to the clothes, the washing can not be finished at one time, the time consumption is long, and the operation of a user is very inconvenient.
For this reason, research and development personnel are gradually involved in the research of washing machines having a plurality of washing chambers. For example, some washing machines having two independent washing tubs are available in the market, and can perform classified washing simultaneously, but the washing tubs of the washing machines occupy more space of the machine body, so that the whole size of the washing machine is increased, and more space of a home is occupied.
Chinese patent CN104805630B discloses a washing machine having a plurality of outer tubs, which can perform washing in a plurality of spaces. The washing machine having a plurality of outer tubs includes: a casing, wherein the first outer barrel is accommodated in the casing; a first door for opening and closing the laundry inlet formed on the housing, the first door having a second tub; a second door for opening and closing the inlet of the second outer barrel; a first water supply unit and a second water supply unit for respectively supplying washing water to the inside of the first outer tub and the inside of the second outer tub; and a first and a second drainage unit for draining the washing water inside the first and the second outer tub. In the technical scheme of this patent, the inside of above-mentioned second outer bucket is located with rotatory mode to the second cylinder and has drive unit, and its revolution mechanic, drive structure and walk line structure etc. are very complicated, and fail safe and reliable is poor, and drive unit's heat dissipation is bad, and the rotation of second cylinder also produces the damage to the door body easily. Therefore, the scheme is easy to have problems in the aspects of sealing, heat dissipation, fixing and the like of motor driving and magnetic field driving, and the manufacturing and maintenance cost is relatively high.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like are generally described with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction. The terms of orientation such as "inner and outer" are generally with respect to the radial direction of the center or center of gravity of the washing machine cavity.
The invention provides a washing machine in a targeted manner in order to realize classified washing, save space and improve the reliability of the whole machine. The invention is explained in detail below with reference to the figures and in connection with preferred embodiments.
Referring to fig. 1 to 6, in the first preferred embodiment, the washing machine according to the present invention includes a first washing unit having a first washing chamber and a second washing unit having a second washing chamber, i.e., it is possible to perform classified washing, improving user satisfaction. In particular, the second washing unit further comprises a gas flow assisted washing system for creating at least a pressure gas flow through the washing liquid in the second washing chamber for improving the flowability of the washing liquid.
The invention adopts a brand new washing mode, namely a pressure airflow auxiliary washing mode to boost the flow of washing liquid, and has better washing efficiency, sterilization and cleaning effects. In particular, the effect of the gas flow assisted scrubbing is more pronounced when the second scrubbing chamber is preferably a static scrubbing chamber. Compared with roller washing, the water flow in the static washing cavity is relatively poor in mobility, rolling drive, electric control wiring and the like are reduced, the installation difficulty and poor installation of a mechanical structure are reduced, and the structural reliability, the electricity utilization safety and the like are greatly improved. The pressure airflow auxiliary washing mode is non-mechanical force washing and is a care type washing mode, and zero abrasion and zero winding are achieved.
In order to realize the classified washing without enlarging the size of the washing machine, as shown in fig. 2 and 3, the second washing chamber is preferably provided in the

As will be appreciated by those skilled in the art, the micro-bubble generating device 503 (or referred to as a micro-bubble generator) is generally used to generate micro-bubbles with a diameter of less than fifty micrometers (μm) when bubbles are generated, and may also be referred to as micro-nano bubbles, micro-bubbles, nano-bubbles, or the like according to the diameter range of the bubbles. The micro-bubble is generated by melting a certain gas (such as air) into water under a specific pressure by changing the physical properties of the water to form a gas-water mixed solution, and then suddenly polymerizing the gas in the water to form micro-bubble water by expanding to release the pressure. The water flow is accelerated by utilizing the abundant kinetic energy stored in the micro-bubble water and the wave of bubble explosion, thereby enhancing the washing effect. Therefore, as a general knowledge, the
