For this purpose, it is an object of the present invention to provide a kind of outdoor units.
It is another object of the present invention to provide a kind of control methods.
It is yet a further object of the present invention to provide a kind of computer readable storage mediums.
To achieve the goals above, a kind of outdoor unit is provided in the first aspect of the present invention technical solution, comprising: machine
Shell, the top of the casing are equipped with the air outlet of outside outlet air；At least one baffle is movably arranged at the air outlet,
The baffle can be opened and closed the air outlet.
The outdoor unit provided through the invention is equipped with the air outlet of outside outlet air at the top of casing, for air-conditioning to be discharged
Air in device after exchanging heat, wherein refer at the top of casing and install fixed back cabinet in the vertical direction upward in outdoor unit
Side；By being movably equipped at least one baffle at air outlet, for opening and closing air outlet, specifically, lead to
The baffle that at least one opening and closing air outlet is set is crossed, on the one hand in outdoor unit normal course of operation, baffle is opened, to ensure
Air discharge channel is unimpeded at air port, in order to avoid circulate between the air and outside air that hinder air outlet to be discharged, it is another
Aspect can be by making flapper closure, to prevent air outlet and wind wheel accumulated snow or other sundries from entering in outdoor unit standby
Air outlet and influence outdoor unit normal operation, reduce outdoor unit a possibility that breaking down, reduce maintenance cost.
It is emphasized that the mode that the baffle of outdoor unit opens or closes can be sliding, rotation, overturning or flexible,
The purpose of opening and closing air outlet can be achieved.The quantity of baffle can be one, it is two or more, wherein baffle number be two
Or when multiple, only need the sum of the area of two or more baffles that can cover the air outlet at the top of outdoor unit, so as to subtract
The area of small every block baffle, to reduce a possibility that being interfered when baffle is opened by external object, it will be understood that outdoor unit is generally pacified
Mounted in small space, if baffle area is larger, it is easy when opening to collide with wall or other external objects, limitation baffle
It is normal to open.It is opened or closed in addition, the direction that baffle opens or closes can be along cabinet top broadside side, it can also be along machine
Narrow side side opens or closes at the top of shell, can also open or close along other directions, such as along outdoor unit top and direction broadside side
Edge is opened or closed in the straight line in 45° angle direction, or a certain vertex Unscrew or closing at the top of outdoor unit, in baffle number
When amount is two or more, different baffles can also be opened or closed along different directions simultaneously, allow baffle to multiple directions
It is opened and closed air outlet, to make full use of the space on outdoor unit periphery, further decreases and receives external object interference when baffle is opened
A possibility that, in order to avoid influence air outlet normal exhaust.
In addition, the outdoor unit in above-mentioned technical proposal provided by the invention can also have following additional technical feature:

Specific embodiment limitation.
Outdoor unit and its control method according to some embodiments of the invention are described referring to Fig. 1 to Figure 11.
As shown in Figure 1, providing a kind of outdoor unit 1 in one embodiment of the present of invention, comprising: casing 11, casing 11
Top is equipped with the air outlet 12 of outside outlet air；Baffle 13 is movably arranged at air outlet 12, and baffle 13 can be opened and closed air outlet
12.In this embodiment, the air outlet 12 of outside outlet air is equipped at the top of casing 11, for being discharged in air conditioner after exchanging heat
Air, wherein the top of casing 11, which refers to, installs the side of fixed back cabinet 11 in the vertical direction upward in outdoor unit 1；
By being movably equipped with a baffle 13 at air outlet 12, for opening and closing air outlet 12, specifically, pass through setting
The baffle 13 of at least one opening and closing air outlet 12, on the one hand in 1 normal course of operation of outdoor unit, baffle 13 is opened, to ensure
Air discharge channel is unimpeded at air outlet 12, in order to avoid flowed between the air and outside air that hinder air outlet 12 to be discharged
It is logical, it on the other hand, can be by closing baffle 13, to prevent 15 accumulated snow of air outlet 12 and wind wheel in 1 standby of outdoor unit
Or other sundries enter air outlet 12 and influence the normal operation of outdoor unit 1, reduce a possibility that outdoor unit breaks down, and reduce dimension
Protect cost.In one particular embodiment of the present invention, as shown in Fig. 2, 13 quantity of baffle of outdoor unit 1 is two, and can edge
The 11 top broadside side of casing of outdoor unit 1 opens or closes air outlet 12.
It is emphasized that above embodiments are only preferred embodiment, protection scope of the present invention is not limited to the above reality
The scheme in example is applied, the mode that the baffle 13 of outdoor unit 1 opens or closes can be sliding, rotation, overturning or flexible, can be real
Now it is opened and closed the purpose of air outlet 12.The quantity of baffle 13 can be one, it is two or more, wherein 13 quantity of baffle be two
Or when multiple, only need the sum of the area of two or more baffles 13 that can cover the air outlet 12 at 1 top of outdoor unit, thus
The area of every block baffle 13 can be reduced, to reduce a possibility that being interfered when baffle 13 is opened by external object, it will be understood that outdoor
Machine 1 is typically mounted at small space, if 13 area of baffle is larger, is easy when opening to touch with wall or other external objects
It hits, limitation baffle is normally opened.In addition, the direction that baffle 13 opens or closes can be along 11 top broadside side of casing open or
It closes, can also open or close, can also be opened or closed along other directions, such as along outdoor unit along 11 top narrow side side of casing
1 top is opened or closed with direction broadside edge in the straight line in 45° angle direction, or is rotated around the 1 a certain vertex in top of outdoor unit
It opens or closes, when 13 quantity of baffle is two or more, different baffles 13 can also play on or off along different directions simultaneously
It closes, subtracts baffle 13 further to make full use of the space on 1 periphery of outdoor unit to multiple directions opening and closing air outlet 12
A possibility that being interfered when small front apron 13 is opened by external object, in order to avoid influence 12 normal exhaust of air outlet.
