[0018] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0019] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0020] See also Figure 1-3In a first aspect, the present invention provides an air-conditioning indoor unit 100, which includes a casing 10, a vortex ring generating device 20, a first driving mechanism 30, a second driving mechanism 40, an air-driving mechanism 50, and a heat exchanger 60. The casing 10 has an inner cavity 101, an air inlet 102 connected to the inner cavity 101, and an air outlet 103 connected to the inner cavity 101. The vortex ring generating device 20 is arranged at the air outlet 103. The first driving mechanism 30 is mounted on the casing 10 and connected to the vortex ring generating device 20. The first driving mechanism 30 is used to drive the vortex ring generating device 20 to swing left and right. The second driving mechanism 40 is mounted on the first driving mechanism 30. The second driving mechanism 40 is used to drive the vortex ring generating device 20 to slide up and down in the vertical direction. The air-driving mechanism 50 is mounted in the inner cavity 101. The air-driving mechanism 50 is used to drive air from the air inlet 102 into the inner cavity 101 and diffuse out from the air outlet 103. The heat exchanger 60 is installed between the air inlet 101 and the wind driving mechanism 50 . The heat exchanger 60 is used to perform heat exchange and temperature reduction on the air entering the inner cavity 101 .

[0021] The air conditioning indoor unit 100 disclosed in this embodiment has two operating modes, one of which is a conventional air conditioning operating mode, i.e., the vortex ring generating device 20 is not operating, and the air driving mechanism 50 drives air from the air inlet 102 into the inner cavity 101, and diffuses out from the air outlet 103 after passing through the heat exchanger 60, thereby cooling the surrounding environment. In the other operating mode, the air driving mechanism 50 is operating while the vortex ring generating device 60 is also operating. The air entering the inner cavity 101 from the air inlet 102 diffuses out from the air outlet 103 after passing through the vortex ring generating device 20, thereby cooling the surrounding environment.

[0022] Exemplarily, the vortex ring generating device 20 may be disposed at the air outlet 103 , but is not limited to being disposed in the middle, above, below, left or right of the air outlet 103 .

[0023] The air-conditioning indoor unit 100 proposed in the first aspect of the present invention forms a vortex ring airflow when the air passes through the vortex ring generating device 20 and is discharged from the air outlet 103, which can effectively expand the air supply range and air supply distance of the air-conditioning indoor unit. Moreover, under the same air supply distance, the wind speed required by the vortex ring generating device 20 is smaller, thereby reducing energy consumption. In addition, the vortex ring airflow formed by the vortex ring generating device 20 has a weak wind feeling, which can provide users with a better blowing experience. Furthermore, by setting a first driving mechanism 30 for driving the vortex ring generating device 20 to swing left and right, and a second driving mechanism 40 for driving the vortex ring generating device 20 to slide up and down in the vertical direction, the vortex ring generating device 20 can realize large-scale and multi-angle directional air supply, further meeting the needs of users, and having a large market space.

[0024] It should be noted that, in some optional embodiments, the air-conditioning indoor unit 100 may not be provided with the second driving mechanism 40 , and the vortex ring generating device 20 only swings left and right under the action of the first driving mechanism 30 .

[0026] In an optional embodiment, the back cover 12 further includes a fifth surrounding wall 123 disposed on the inner side of the fourth surrounding wall 122. The fifth surrounding wall 123 faces the third surrounding wall 114 and is spaced apart from the inner side of the third surrounding wall 114. The fourth surrounding wall 122 and the fifth surrounding wall 123 enclose an airflow channel, and the air entering the inner cavity 101 from the air inlet 102 is blown out to the outside through the airflow channel enclosed by the fourth surrounding wall 122 and the fifth surrounding wall 123. This arrangement reduces the cross-sectional area of ​​the airflow blowing outward, so that when the wind-driving mechanism 50 is operating at low power, the airflow blowing out from the air outlet 103 can also have a relatively high flow rate, thereby reducing energy consumption.
