[0099] The utility model also provides an air conditioner, which comprises the above-mentioned air conditioner indoor unit.

[0100] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0101] In the air conditioner indoor unit provided by the utility model, the air conditioner indoor unit includes an air conditioner main body 10, a preset air duct 20, a preset air outlet component 30 and a damper 40. The preset air duct 20 is arranged on the air conditioner main body 10; the outer end of the preset air duct 20 is an air outlet. The preset air outlet component 30 is located outside the air conditioner main body 10, and the preset air outlet component 30 has an air outlet channel 31; the preset air outlet component 30 is connected to the air conditioner main body 10 so that the first end of the air outlet channel 31 is connected to the side of the preset air duct 20, and the second end of the air outlet channel 31 is used for air outlet. The damper 40 is movably arranged to have a first state and a second state; when the damper 40 is in the first state, the damper 40 blocks the outer port of the preset air duct 20 and avoids the first port of the air outlet channel 31, and the wind in the preset air duct 20 can only pass through the air outlet channel 31 and be discharged from the second port of the air outlet channel 31; when the damper 40 is in the second state, the damper 40 blocks the first port of the air outlet channel 31 and avoids the outer port of the preset air duct 20, and the wind in the preset air duct 20 can only be discharged from the outer port of the preset air duct 20. One of the outer port of the preset air duct 20 and the second port of the air outlet channel 31 is arranged obliquely upward or upward, and the other is arranged obliquely downward or downward.

[0102] When the preset air duct 20 and the air outlet duct 31 adopt the first setting mode, the outer port of the preset air duct 20 is set obliquely upward or upward, and the second port of the air outlet duct 31 is set obliquely downward or downward, so that the outer port of the preset air duct 20 blows air upward, and the second port of the air outlet duct 31 blows air downward. At this time, when the air conditioner indoor unit blows hot air, the damper 40 is in the first state; when the air conditioner indoor unit blows cold air, the damper 40 is in the second state.

[0103] When the preset air duct 20 and the air outlet duct 31 adopt the second setting mode, the outer port of the preset air duct 20 is set obliquely downward or downward, and the second port of the air outlet duct 31 is set obliquely upward or upward, so that the outer port of the preset air duct 20 blows air downward, and the second port of the air outlet duct 31 blows air upward. At this time, when the air conditioner indoor unit blows hot air, the damper 40 is in the second state; when the air conditioner indoor unit blows cold air, the damper 40 is in the first state.

[0104] In the specific implementation process, when the air conditioner starts the heating mode and the air conditioner indoor unit blows hot air, the hot air blows downward, and the hot air will slowly float upward from the indoor floor, so that the indoor temperature can be controlled in a carpet-like manner. When the air conditioner starts the cooling mode and the air conditioner indoor unit blows cold air, the cold air blows upward, and the cold air will slowly fall from the upper part of the room, so that the indoor temperature can be cooled in a shower-like manner. It can be seen that the air conditioner indoor unit of the present application can solve the problem of cold air blowing on people, thereby improving comfort.

[0105] The air conditioner indoor unit of the present application can achieve upward air outlet for cooling and downward air outlet for heating, realizing shower-like air supply for cooling and carpet-like air supply for heating, thereby improving the comfort of the air conditioner; and the air inlet 14 of the air conditioner is downward, which solves the problem of dust accumulation at the air inlet when the air conditioner is idle.

[0106] The air-conditioning indoor unit of the present application: 1. Solve the problem of single air outlet mode and poor comfort of ordinary wall-mounted air conditioners; 2. Solve the problem of additional insulation required for switching air ducts; 3. Solve the problem of needing multiple air guide plates and multiple motion mechanisms to complete air guide direction switching; 4. Solve the problem of poor dust prevention after the air conditioner is turned off; 5. Solve the problem of needing to select an operating mode when turning on the air conditioner.

[0107] The indoor unit of the air conditioner of the present application has air outlets up and down, which can prevent direct blowing in the entire cooling area; it can effectively prevent dust accumulation at the air inlet when the air conditioner is idle; it can realize air duct switching by using a damper and a motor, which has a simple structure and low cost. Moreover, when switching the air duct, the hot air blows downward, and no additional insulation is required, and no condensation water will be generated on the surface of the air duct, which is reliable and practical.
