[0007] The vortex ring generating device provided by the present invention comprises an air outlet cavity, a vortex ring generating part and a fan assembly. The air flow area of ​​the air outlet end of the air outlet cavity is smaller than the air flow area of ​​the air inlet end. The vortex ring generating part can periodically drive the gas in the air outlet cavity along the air inlet direction, that is, the vortex ring generating part generates disturbances in the air inlet direction to the gas in the air outlet cavity. The fan assembly is provided with a vortex ring generating part on one side away from the air outlet cavity, which can drive the airflow into the vortex ring generating part, so that the airflow driven by the fan assembly forms a vortex ring airflow from the gas blown out of the air outlet end through the vortex ring generating part, thereby realizing vortex air supply. The vortex air supply makes the airflow blown out of the indoor unit of the air conditioner have a large variation range, a long air supply distance and a wide radiation range; at the same time, the vortex air supply can realize windless air supply and reduce energy consumption.

[0093] In one embodiment of the present invention, preferably, the driving part includes: a driving member (not shown); a shift fork 402 connected to the driving disk 2102; a transmission member, the transmission member is connected to the driving member, and the transmission member transmits the movement of the driving member to the shift fork 402 so that the shift fork 402 moves to drive the driving disk 2102 to rotate.

It can be understood that the transmission member can be other mechanisms that meet the requirements.

[0097] On the one hand, the driving member is a motor, and the driving member and the fan assembly share a motor, which effectively reduces the production cost of the product and can reduce the space occupied by the vortex ring generating device 100, which is conducive to sufficient space for airflow to circulate, and thus facilitates the formation of the vortex ring and ensures a good air outlet effect; on the other hand, the driving member is a separately arranged motor, which can make the blades 202 rotate at different frequencies, and thus can make the airflow channel open or close at different frequencies, and can adjust the output range and output distance of the vortex ring airflow to achieve personalized air outlet to meet the needs of different users and improve the market competitiveness of the product.

By rotating the blade 202 90° to open the closed vortex ring generating part, it can ensure that the wind has a larger flow area, effectively promote the formation of vortex ring airflow, and ensure that the vortex ring airflow output range is large and the output distance is long, thereby ensuring a good wind output effect.

[0112] like Fig. 22 As shown, the number of the air outlet 22, the air inlet 24 and the vortex ring generating device 100 is equal and at least one, and at least one vortex ring generating device 100 is respectively connected to each corresponding air inlet 24 and each air outlet 22, so that each air outlet 22 of the air conditioner 200 can realize the air outlet in the vortex ring airflow mode, and can ensure that the vortex ring airflow of each air outlet 22 is sufficient, thereby improving the user's blowing experience. Further, the output distance and output range of the vortex ring airflow discharged from each air outlet 22 can be the same or different, which can meet the use needs of different users. The output distance and output range of the vortex ring airflow discharged from each air outlet 22 are the same, which is convenient to set and convenient for user operation. The output distance and output range of the vortex ring airflow discharged from each air outlet 22 are different, which can realize different personalized air supply modes in the same space, thereby meeting the needs of different users in the same space, further improving the user's satisfaction and improving the market competitiveness of the product. It can be understood that when the number of air outlets 22 is multiple, one or more of them can be set as a conventional air outlet mode to meet the needs of different users.

[0113] The shape of the air outlet 22 is circular, elliptical, square or rectangular. The various shapes of the air outlet 22 can meet the needs of different setting positions of the air outlet 22, and can also meet the user's needs for various air outlet cross-sections. At the same time, air outlets 22 of various shapes are arranged on the shell of the air conditioner 200 to meet the demand for beautiful appearance of the air conditioner 200, thereby improving the market competitiveness of the product. It is understandable that the air outlet 22 can also be other special shapes.

[0114] Multiple air inlets 24 are arranged on one or more sides of the shell of the air conditioner 200, which can meet the needs of different fan types and have a wide range of applications.

[0118] Furthermore, the air inlet 24 and the air outlet 22 of the air conditioner 200 may be closed in the form of an up and down sliding switch door or horizontal grille blades, or in other forms that meet the requirements.

The wind generated by the axial flow fan 10 flows to the air outlet cavity 30 in a pulsed manner through the opening or closing of the vortex ring generating part. Since the outlet end of the air outlet cavity 30 is connected to the air outlet 22, the air outlet of the air outlet cavity 30 is The cross-sectional area of ​​the outlet end is reduced, so that the wind flowing through the vortex ring generating part is discharged through the outlet end of the air outlet cavity 30 and forms a vortex ring airflow, which effectively expands the air supply range and air supply distance of the air conditioner 200, and the vortex ring airflow is discharged from the outlet end of the air outlet cavity 30 by the air outlet 22, realizing directional propagation of air supply. Compared with the existing air conditioner 200, the vortex ring generating device 100 reduces the wind speed required for the same distance of wind propagation, thereby greatly reducing energy consumption and realizing personalized air supply, reducing the user's use cost and improving the user's use experience. At the same time, the wind of the existing air conditioner 200 is discharged in the form of a fixed airflow, which makes the user feel that the airflow is concentrated and the wind force is large, while the wind is discharged from the outlet end of the air outlet cavity 30 through the vortex ring generating part in the form of a vortex ring airflow, which can make the user feel that there is no wind.

[0120] In a specific embodiment, Fig.23 As shown, the diameter of the outlet end of the air outlet cavity 30 of the vortex ring generating device 100 is Ds, and the diameter of the inlet end arranged opposite to the outlet end of the air outlet cavity 30 is Db, and Ds is smaller than Db; the diameter of the motor cover of the first motor 50 is Dm, and the diameter of the fixing ring 2104 of the vortex ring generating device 100 is Dt. In order to promote the formation of the vortex ring airflow and ensure that the output range of the vortex ring airflow is large and the output distance is long, Dt is reduced so that Dt is equal to Dm.

Further, increasing the operating speed of the fan can also promote the formation of the vortex ring airflow.

[0121] In a specific embodiment, the output speed of the vortex ring airflow is 0.5m / s to 5m / s. When the output speed of the vortex ring airflow is 2m / s to 2.5m / s and the diameter of the output range of the vortex ring airflow is 0.1m to 0.5m, the human body feels more comfortable and can have an experience without feeling of wind.
