The indoor unit in the above embodiment may also be used in the technical field of air conditioning apparatuses, that is, according to another aspect of the present application, an air conditioner is provided, including an indoor unit, where the indoor unit is the indoor unit in the above embodiment.
According to another aspect of the present application, there is provided a control method of an air conditioner for controlling the air conditioner in the above embodiment, the method including the steps of: when the indoor unit is in the air inlet mode of the upper air inlet 11 and the lower air inlet 12, the air guide assembly 30 is controlled to be positioned at the air guide position so that air flow outside the shell 10 is discharged outside the shell 10 after passing through the first channel 142, the cooling channel 40 and the second channel 143; when the indoor unit is in the air outlet mode of the upper air inlet 11 and the lower air inlet 12, the air guide assembly 30 is controlled to be positioned at a non-air guide position, and at this time, no air flows pass through the first channel 142, the cooling channel 40 and the second channel 143. The negative pressure formed in the lower cavity in the heating mode can drive the air flow in the cooling channel to flow towards one side of the lower air opening.
Specifically, the air conditioner is adopted, so that the problem of heat dissipation of a screen, namely a display device, arranged on the panel body is solved when the air conditioner heats up. When the air conditioner is used for refrigerating, the problem that cold air directly blows to the rear end face of the screen is avoided. The indoor natural wind is utilized to perform heat exchange, the effect of screen cooling is achieved, the structure is simple and reliable, negative pressure generated by the air outlet when heating is utilized to drive air flow, and the energy consumption is greatly reduced. When in refrigeration, the inner air deflector is automatically closed, so that cold air does not directly blow the rear end face of the screen, and condensation water generated by the screen is avoided.
The negative pressure generated by the lower air outlet when the air conditioner heats up drives the indoor cold air to flow through the rear end face of the screen for heat exchange, thereby achieving the aim of cooling the screen. When in refrigeration, the air deflector assembly is closed, so that upward cold air can not be directly blown onto the rear end face of the screen, and the screen is prevented from generating condensation.
As shown in fig. 1, in the present embodiment, the screen heat dissipation system of the air conditioner is composed of a bottom case member, a panel body, an air deflector assembly, a screen, a panel, and the like. The air deflector is arranged on the panel body, and the air deflector is opened and closed by driving the connecting rod through 1 stepping motor. The panel body is mounted on the bottom chassis member, and then the screen is mounted on the panel body, and the panel 60 is mounted after being fixedly locked. A larger gap is reserved between the screen and the panel body, so that ventilation can be realized.
When the air conditioner is in heating operation, the stepping motor drives the connecting rod to drive the inner air deflector to open by 30 degrees, and at the moment, the negative pressure generated by the heated lower air outlet drives the air flow in the 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 opened and connected with indoor air, fresh cold air flows downwards from the upper end and exchanges heat with the screen, so that heat is taken away for cooling.
When the air conditioner inner cooling machine operates, 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 deflector can prevent the cold air from directly blowing the rear end surface of the screen, so as to avoid condensation water generated by supercooling the screen, as shown in fig. 3. Meanwhile, a larger gap is reserved between the screen and the panel body, heat transfer can be blocked, and the effect is good.
