The arrangement enables the first air deflector 21 to rotate around the first rotating shaft 22, and the working reliability of the first air deflector 21 is improved.
The second wind guiding assembly 30 includes a second rotating shaft 32, the second rotating shaft 32 is connected with the panel body of the casing assembly 10, the second rotating shaft 32 is located outside the first rotating shaft 22, the first rotating shaft 22 and the second rotating shaft 32 are arranged in parallel, and the second wind guiding plate 31 is connected with the second rotating shaft 32. The arrangement enables the second air guiding plate 31 to rotate around the second rotating shaft 32, and improves the working reliability of the second air guiding plate 31.
When the first air guiding plate 21 is located at the first closed position and the second air guiding plate 31 is located at the first air guiding position, the air guiding surface 211 of the first air guiding plate 21 is flush with the air guiding surface 311 of the second air guiding plate 31, so that the noise of the air flow is effectively reduced.
In order to further reduce the noise of the airflow, the air guiding surface 211 at the second end of the first air guiding plate 21 may be a curved surface.
The indoor unit in the above embodiment may also be used in the technical field of air conditioner equipment, that is, according to another aspect of the present invention, there is provided an air conditioner, including an indoor unit, where the indoor unit is the indoor unit in the above embodiment.
According to another aspect of the present invention, there is provided a control method of an air conditioner, the method being used for the air conditioner in the above embodiment, the method comprising the steps of: the air conditioner has a refrigerating mode and a heating mode, and when the air conditioner is controlled to be in the refrigerating mode, the second air deflector 31 is controlled to rotate for a preset angle along a preset direction and then is positioned at a first air guiding position; when the air conditioner is controlled to be in a heating mode, the first air guide plate 21 is controlled to rotate for a preset angle along the preset direction and then to be located at the first opening position, and the second air guide plate 31 is controlled to rotate for a preset angle along the preset direction and then to be located at the second air guide position. By the arrangement, when the air conditioner is in a cooling mode and a heating mode, the first air deflector 21 and the second air deflector 31 are conveniently controlled to rotate to the optimal air guiding position, and the air outlet comfort of the air conditioner is further improved.

This arrangement improves the reliability of the air conditioner.
Specifically, as shown in fig. 4, which is a flowchart according to an embodiment of the control method of the air conditioner in the cooling mode according to the present application, when the air conditioner starts the cooling mode, the motor of the second air deflector 31 receives a signal transmitted by the main control system, and drives the second air deflector 31 to rotate counterclockwise around the second rotating shaft 32 by a certain angle e (the angle may be changed, and the approximate range is 30 ° to 50 °), at this time, the fan blade is started, the cooling mode is normally operated, the air conditioner blows air, after receiving a shutdown signal, the fan blade is turned off, the second air deflector 31 is rotated to a closed position, the air conditioner completes shutdown, and if the shutdown signal is not received, the cooling mode is kept to normally operate, and the air is blown out.
As shown in fig. 5, which is a flowchart illustrating an embodiment of a control method for an air conditioner in a heating mode according to the present application, when the air conditioner is turned on in the heating mode, the driving motor of the first air deflector 21 receives the signal transmitted by the main control system, drives the first air deflector 21 to rotate anticlockwise around the first rotating shaft 22 by a certain angle f, (the angle can be changed, and is about 40-70 degrees), the motor of the second air deflector 31 receives the signal transmitted by the main control system, drives the second air deflector 31 to rotate clockwise around the second rotating shaft 32 by 45 degrees, at the moment, the fan blade is started to heat and blow air, the heating mode is normal operation, the air is discharged from the air conditioner, after the shutdown signal is received, and (3) shutting down the fan blades, firstly rotating the second air guide plate 31 to a closed position, then closing the first air guide plate 21, completing shutdown of the air conditioner, and if a shutdown signal is not received, keeping normal operation in a heating mode to realize downward air outlet.
In another embodiment of the present invention, in order to avoid noise generation during heating, the upper end of the first air guiding plate 21 is smoothly transited as shown in fig. 6. Under the heating condition, the first air deflector 21 and the second air deflector 31 are both opened, and hot air is blown out from the lower side of the air outlet. After receiving a shutdown signal under the heating working condition, the fan blade stops, the second air deflector 31 is reset and closed anticlockwise, and then the first air deflector 21 rotates and closes clockwise.
In another embodiment of the present application, the first air guiding plate 21 and the second air guiding plate 31 are directly assembled on the bottom casing to rotate around the axis, the left sides of the first air guiding plate 21 and the second air guiding plate 31 have circular pins to be matched with the axis holes on the bottom casing, and the right sides have axis holes to be matched with the motor and driven by the motor to rotate. The second air deflector 31 rotates around the second rotating shaft 32, and can rotate clockwise or counterclockwise; the first air guiding plate 21 rotates counterclockwise around the first rotating shaft 22.
Specifically, the purpose of the design is that through the mutual matching of the first air deflector 21 and the second air deflector 31, during refrigeration, cold air is blown upwards through the second air deflector 31, so that the effect that cold air does not blow people is achieved, and a shower type refrigeration effect is achieved. The first air deflector 21 and the second air deflector 31 are assembled on the bottom shell and move in a matched mode to achieve up-and-down air supply, during refrigeration, the first air deflector 21 is fixed, the second air deflector 31 is opened around the second rotating shaft 32 in an anticlockwise rotating mode, during heating, the second air deflector 31 is opened in a clockwise rotating mode, meanwhile, the first air deflector 21 is opened around the first rotating shaft 22 in an anticlockwise rotating mode to form a heating air channel, lower air outlet is achieved, and air outlet airflow is far away from the air inlet during heating. In this embodiment, the problem that the air conditioner can not simultaneously realize remote air-out of refrigeration, heating and down pressing and air supply, heat exchange efficiency is not high, room temperature distribution is uneven, comfortableness is not good and air conditioning cold blowing people, aviation baffle condensation and the like is solved.
