[0002] With the improvement of people's living standards and quality of life, air conditioners, especially multi-purpose air conditioners with cooling and heating functions, have become indispensable appliances for home and office use. Typically, the indoor unit of an air conditioner consists of a casing, a panel, a heat exchanger, crossflow blades, and an air supply and deflector. A typical air conditioner structure features an air inlet and an outlet, with the outlet located near the bottom of the unit. During operation, the airflow is redirected by rotating the air deflector at the outlet, delivering cool air downward and hot air upward.

[0003] However, due to the location limitation of the air outlet of the air conditioner, which is close to the bottom of the indoor unit, the air outlet direction control effect of cooling and heating is not obvious, resulting in the cold air still blowing to the user during cooling, while the hot air is sent up but does not blow to the user during heating.

[0052] In order to ensure that the rack can move along a fixed track during the movement of the gear-driven rack, a slide groove or slide rail is formed on the side of the rack, and a slide rail or slide groove is formed on the inner side of the shell 11 accordingly; the slide groove and the slide rail cooperate to realize the movement of the rack relative to the shell 11; in this embodiment, a slide rail is formed on the side of the rack, and a slide groove is formed on the side of the shell 11 accordingly; specifically, the rack is an arc-shaped rack, and internal teeth are formed on the inner side thereof, which mesh with the external teeth of the gear; the slide rail is an arc-shaped slide rail, and the center line of the arc-shaped slide rail coincides with the axis center line of the fan 22.

[0063] like Figure 2c As shown, the air conditioner indoor unit provided in this embodiment supplies air upward and downward at the same time. Under the action of the first driving mechanism, the first air guide 31 is close to the front and lower side of the heat exchanger 21, the first air outlet 3 is connected, the first air guide plate 33 is at a certain angle to the shell 11, and the first air outlet 32 ​​is opened; under the action of the second driving mechanism, the second air guide 41 is attached to the second bottom shell 442, the second air outlet 4 is connected, the second air guide plate 43 is at a certain angle to the cross-sectional direction of the second air outlet 42, and the second air outlet 42 is opened; the fan 22 and Two air outlet ducts are formed between the second air outlet 42; under the action of the fan 22, the indoor air enters the shell 11 and completes heat exchange with the heat exchanger 21, and is then discharged through the first air outlet 32, and is sent upward under the action of the first air guide plate 33, and is discharged through the second air outlet 42, and is sent downward under the action of the second air guide plate 43; at the same time, the optimal air supply direction can be achieved according to actual needs based on the angle between the first air guide plate 33 and the shell 11, and the angle between the second air guide plate 43 and the cross-sectional direction of the second air outlet 42.

[0064] Theoretically, the air entering the shell 11 may be divided into two streams through the heat exchanger 21 and the fan 22, flowing out from the first air outlet 3 and the second air outlet 4 respectively, forming simultaneous upper and lower air outlets. However, from the analysis of the air duct characteristics, due to the special position relationship of the first air guide 31, most of the air still flows out from the first air outlet 3, while the air volume flowing out of the second air outlet 4 is very small.
