In the heating mode, the negative pressure formed in the lower cavity can drive the airflow in the cooling channel to flow towards one side of the lower air opening.
Particularly, when the air conditioner is adopted, the problem that the screen, namely the display device, arranged on the panel body dissipates heat is solved when an inner machine of the air conditioner heats. When the air conditioner is used for refrigerating, cold air is not directly blown to the rear end face of the screen. Utilize indoor natural wind to carry out the heat exchange, reach the effect of screen cooling, this simple structure is reliable, utilizes the negative pressure that the air-out produced down to drive the air current during heating, greatly reduced energy consumption. When in refrigeration, the internal air deflector is automatically closed, so that cold air is not directly blown to the rear end face of the screen, and the screen is prevented from generating condensed water.
The negative pressure generated by the lower air outlet during heating in the air conditioner drives the indoor cold air to flow through the rear end face of the screen for heat exchange, thereby achieving the purpose of cooling the screen. During refrigeration, the air guide plate component is closed, so that upward cold air cannot be directly blown to the rear end face of the screen, and condensation of the screen is avoided.

The air guide plate is arranged on the panel body, and the 1 stepping motor drives the connecting rod to drive the connecting rod to open and close the air guide plate. The panel body is mounted on the bottom shell member, and then the screen is mounted on the panel body, and the panel 60 is mounted after being fixed and locked. A large gap is reserved between the screen and the panel body, and ventilation can be achieved.
When the air conditioner indoor unit is heated, the stepping motor drives the connecting rod to drive the inner air deflector to open by 30 degrees, and at the moment, negative pressure generated by heated lower air outlet drives airflow in a cooling channel between the panel body and the screen to flow downwards, as shown in fig. 2. The upper end and the lower end of the cooling channel are both provided with openings and connected with indoor air, fresh cold air flows downwards from the upper end and exchanges heat with the screen, and therefore heat is taken away to cool.
When the air conditioner indoor unit operates in a refrigerating mode, the stepping motor drives the connecting rod to drive the inner air deflector to be closed. At this time, the cold air flows from bottom to top, and the closed air guide plate can prevent the cold air from directly blowing the rear end face of the screen, so as to avoid the generation of condensed water due to the overcooling of the screen, as shown in fig. 3. Meanwhile, a large gap is reserved between the screen and the panel body, so that heat transfer can be blocked, and the effect is good.
