Further, the vortex ring member 2 is installed in the air duct, and the vortex ring member 2 has an air inlet end 21 and an air outlet end 22, and the air inlet area of the air inlet end 21 is larger than the air outlet area of the air outlet end 22, so that the air entering from the air inlet end 21 of the vortex ring member 2 forms annular air after passing through the air outlet end 22. The difference between the air inlet area of the air inlet end 21 and the air outlet area of the air outlet end 22 can be set according to actual requirements, and there is no limitation here.
Further, when the number of the air inlets 14 and the air outlets 13 is plural, the air inlet end 21 of the scroll member 2 is communicated with at least one of the air inlets 14, and the air outlet end 22 of the scroll member 2 is communicated with at least one of the air outlets 13, so that the air of at least one of the air inlets 14 passes through the scroll member 2 and is discharged from at least one of the air outlets 13. Taking a cabinet air-conditioning indoor unit as an example, the scroll ring 2 is provided with an upper end inside the casing 1, that is, the air outlet 13 opposite to the scroll ring 2 is provided at the upper end of the front panel 11, so that when the air blown out through the scroll ring 2 forms scroll air and is blown out from the air outlet 13, the scroll air can be sent to the far end indoors in an annular manner, that is, under the same air volume, the scroll ring can blow the formed scroll air farther, thereby reducing the energy consumption of the air-conditioning indoor unit.

And the first fan 3 is located between the scroll member 2 and the air inlet 14, that is, the first fan 3 is located between the scroll member 2 and at least one air inlet 14 opposite to the scroll member 2, in this embodiment, by setting the operation parameters of the first fan 3, for example, increasing the operation rotation speed, operation frequency, and the like of the first fan 3, the speed of the wind entering the air inlet 14 can be increased, that is, the vortex ring wind formed after the wind passes through the scroll member 2 is blown out from the air outlet 13 at a higher speed.
Further, the wind shielding member 4 is movably connected to the wind inlet end 21 of the scroll member 2, so that the wind shielding member 4 can open or close the wind inlet end 21 of the scroll member 2. Specifically, when the wind shielding member 4 opens the wind inlet end 21 of the scroll member 2, wind can be blown in from the wind inlet 14 opposite to the wind inlet end 21 of the scroll member 2, and wind blown out from the wind outlet end 22 after passing through the scroll member 2 forms scroll wind, and then is blown into the room from the wind outlet 13 opposite to the wind outlet end 22; when the wind shielding part 4 closes the wind inlet end 21 of the vortex part 2, at the moment, the first fan 3 is closed, wind cannot pass through the wind inlet end 21 of the vortex part 2, enters the shell 1 from the rest of the wind inlets 14, exchanges heat through a heat exchange device and the like in the shell 1, and is blown out from the rest of the wind outlets 13, so that the normal refrigeration or heating mode of the indoor unit of the air conditioner is realized.
Further, the driving member 5 is connected to the wind shielding member 4, and the driving member 5 drives the wind shielding member 4 to open or close the wind inlet end 21 of the scroll member 2. The operation modes of the indoor unit of the air conditioner include multiple types, such as: a cooling mode, a heating mode, and a pulse mode. In this embodiment, taking the pulse mode of operation of the air conditioning indoor unit as an example, the initial state of the wind shielding member 4 when the air conditioning indoor unit is shut down is a closed state, that is, the initial state of the wind shielding member 4 is the air inlet end 21 of the closed scroll member 2, when the air conditioning indoor unit operates in the pulse mode, the driving member 5 drives the wind shielding member 4 to switch from the closed state to the open state, and the time that the wind shielding member 4 is in the open state is 0.05s to 0.5s, when the wind shielding member 4 is in the closed state, high pressure is formed between the air inlet 13 and the wind shielding member 4, at the instant the wind shielding member 4 is opened, the wind passing through the scroll member 2 is high pressure wind, that is, the high pressure wind flows from the air inlet end 21 with a larger area into the air outlet end 22 with a smaller area, so that the wind speed of the high pressure wind is faster, and the high pressure wind forms vortex ring wind. Then, the wind shielding member 4 is continuously driven to switch from the open state to the closed state to complete one of the vortex winds. Alternatively, the time for which the wind shield 4 is in the open state is 0.1 s. However, in other embodiments, the time that the windshield 4 is in the open state may be set to other values, and is not limited herein.
Further, the formation of the vortex ring wind after the blowout of the blowout port 13 is intermittent, that is, there is a certain interval time between each vortex ring wind, that is, the interval time is a time from the last opening of the wind shielding member 4 to the next opening of the wind shielding member 4. The interval time is more than 1s, and the setting can be specifically carried out according to the air conditioner indoor unit and the user requirements. Optionally, the interval time is 1.4 s.
