Referring to fig. 1 and fig. 2, an indoor unit 10 of an air conditioner is provided, where the indoor unit 10 of the air conditioner includes a casing 100, a vortex ring generator 200, a wind driving mechanism 300, and a heat exchanger 400. The housing 100 has an inner cavity 103, an air inlet 101 and an air outlet 102, and both the air inlet 101 and the air outlet 102 are communicated with the inner cavity 103. The wind-driving mechanism 300 is installed in the inner cavity 103, and the wind-driving mechanism 300 is used for driving air to enter the inner cavity 103 from the air inlet 101 and diffuse out from the air outlet 102. The heat exchanger 400 is installed between the air outlet 102 and the wind driving mechanism 300, and the heat exchanger 400 is used for exchanging heat and reducing the temperature of air entering the inner cavity 103. Wherein, the vortex ring generating device 200 is installed at the air inlet 101; the indoor unit 10 of the air conditioner further includes a driving mechanism 600, the driving mechanism 600 is installed at the air inlet 101 and connected to the vortex ring generating device 200, and the driving mechanism 600 is configured to drive the vortex ring generating device 200 to move along the first direction. It is understood that the intake vent 101 includes, but is not limited to, above, below, to the left, and to the right of the intake vent 101. Through the technical scheme, the vortex ring generating device 200 is arranged at the air inlet 101, air at the air inlet 101 generates vortex ring airflow through the vortex ring generating device 200, then flows to the air outlet 102 through the inner cavity 103, and the vortex ring airflow is diffused to the outside of the indoor air conditioner unit 10 through the air outlet 102. The vortex ring airflow generated by the vortex ring generating device 200 can effectively expand the air supply range and the air supply distance of the indoor unit 10 of the air conditioner; under the same air supply distance, the required air speed of the vortex ring generating device 200 is smaller, so that the energy consumption can be reduced; in addition, the vortex ring airflow formed by the vortex ring generating device 200 has weak wind feeling, so that the user can have better wind blowing experience. Further, the driving mechanism 600 is arranged to drive the vortex ring generating device 200 to move along the first direction, so that large-range and multi-angle directional air supply of the vortex ring generating device 200 can be realized, the requirements of users are further met, and the large market space is provided.

The indoor unit 10 of the air conditioner disclosed in this embodiment has two operation modes, wherein one of the operation modes is an operation mode of a conventional air conditioner, that is, the vortex ring generating device 200 does not operate, and the air driving mechanism 300 drives air to enter the inner cavity 103 from the air inlet 101, and diffuse out from the air outlet 102 after passing through the heat exchanger 400, so as to cool the surrounding environment. In another working mode, when the wind driving mechanism 300 is in operation, the vortex ring generating device 200 is also in operation, and air entering the inner cavity 103 from the wind inlet 101 is diffused out from the wind outlet 102 under the action of the vortex ring generating device 200 to cool the surrounding environment.

Referring to fig. 1 and fig. 3 to fig. 5, an air conditioning indoor unit 10 is provided, where the air conditioning indoor unit 10 includes a casing 100, a vortex ring generating device 200, a wind driving mechanism 300, and a heat exchanger 400. The housing 100 has an inner cavity 103, an air inlet 101 and an air outlet 102, and both the air inlet 101 and the air outlet 102 are communicated with the inner cavity 103. The wind-driving mechanism 300 is installed in the inner cavity 103, and the wind-driving mechanism 300 is used for driving air to enter the inner cavity 103 from the air inlet 101 and diffuse out from the air outlet 102. The heat exchanger 400 is installed between the air outlet 102 and the wind driving mechanism 300, and the heat exchanger 400 is used for exchanging heat and reducing the temperature of air entering the inner cavity 103. The vortex ring generator 200 is installed in the casing 100 and includes a first vortex ring generator 210 and a second vortex ring generator 220. The first vortex ring generator 210 and the second vortex ring generator 220 are both installed at the air inlet 101; it is to be understood that the first vortex ring generator 210 and the second vortex ring generator 220 may also be installed at the air outlet 102. It is understood that the outlet 102 includes, but is not limited to, above, below, to the left, and to the right of the outlet 102.

Referring to fig. 3 to 5 in conjunction with fig. 15 and 16, in an alternative embodiment, the casing 100 includes a first baffle 110, a second baffle 150, a first shell 120, a second shell 140, and an air duct 130.

It can be understood that the cross-sectional area of the air inlet 101 is larger than that of the air outlet 102, and this arrangement reduces the cross-sectional area of the airflow blown out, so that the airflow blown out from the air outlet 102 can have a larger flow velocity under the condition of low-power operation of the wind driving mechanism 300, and thus, the effect of reducing energy consumption is achieved.

Referring to fig. 4 and 5, in an alternative embodiment, the first baffle 110 is provided with a first grille through which the external air enters the air inlet 101. Referring to fig. 3 to 5, in another alternative embodiment, a second grille is disposed on the second baffle 150, and the air flow in the air outlet 102 is diffused into the room through the second grille.

Referring to fig. 5, in another alternative embodiment, the first baffle 110 is provided with a first mounting portion on which the first vortex ring generator 210 is mounted. Illustratively, the first mounting portion is hollow in structure, i.e., the airflow in the inner cavity 103 does not flow through the first vortex ring generator 210 through the first grill. It can be understood that compared to the structure that the airflow in the inner cavity 103 passes through the first vortex ring generator 210 through the grating, the airflow in the inner cavity 103 passes through the first vortex ring generator 210 without passing through the grating, so that the vortex ring airflow passing through the first vortex ring generator 210 is wider and stronger, and has a greater influence on the airflow in the inner cavity 103.

Referring to fig. 2, in an alternative embodiment, the second baffle 150 is provided with a fourth mounting portion, and the second vortex ring generator 220 is mounted on the fourth mounting portion. Referring to fig. 5, in another alternative embodiment, the first baffle 110 is provided with a second mounting portion, and the second vortex ring generator 220 is mounted on the second mounting portion.

It can be understood that, by moving the movable plate 112, the gap between the movable plate 112 and the air inlet 101 can be adjusted, so as to adjust the area entering the air inlet 101, and thus adjust the air supply amount of the indoor air conditioner 10, so that the indoor air conditioner 10 has more air supply modes and more diversity. Meanwhile, due to the movable structure of the movable plate 112, the movable plate 112 can be cleaned more conveniently as ash is accumulated on the movable plate 112.

In an alternative embodiment, the drive mechanism 600 includes a transmission and a motor. The transmission member is connected with the movable plate 112; the motor is connected with the transmission piece and used for driving the transmission piece to move along the first direction.
