By the setting of position of splitter, being separated by main air duct and go to upper and lower two sub-air channels, upper secondary air channel is corresponding with upper sub-air channel
Connection, the connection corresponding with lower sub-air channel of lower secondary air channel, upper and lower secondary air channel carries out wind-guiding to upper and lower sub-air channel respectively.By shunting
The setting of part so that the air-flow in sub-air channel will not be produced turbulent flow etc. due to colleague by multiple secondary air channel effects, is conducive to
Air-conditioner is blown more accurately and efficiently.
In order to improve the air-supply efficiency in each sub-air channel, described position of splitter includes the first conduction part and the second conduction part, institute
Stating the first conduction part and have the first drain face towards spiral case 600 first side, described second conduction part has towards described spiral case
Second drain face of 600 second sides；
Described first drain face is correspondingly arranged with the wind-guiding face of spiral case 600 first side；
Described second drain face is correspondingly arranged with the wind-guiding face of spiral case 600 second side.
Specifically, in the present embodiment, the wind-guiding face of the first drain face and spiral case 600 first side is as the side in a sub-air channel
Wall, the common flowing guiding air-flow.The bearing of trend in the wind-guiding face of the first drain face and spiral case 600 first side is close, by air-flow
Guiding toward same direction, beneficially air-flow can flow in sub-air channel more smoothly.In like manner, the second drain face and spiral case 600
The wind-guiding face of the second side is as the sidewall in another sub-air channel, the common flowing guiding air-flow.Second drain face and spiral case 600
The bearing of trend in the wind-guiding face of two sides is close, is guided toward same direction by air-flow, and beneficially air-flow can be more suitable in sub-air channel
Smooth flowing.
The present invention further provides the control method of a kind of through-flow air-conditioner, wall-hanging air conditioner have main air duct and with institute
Stating the secondary air channel of main air duct connection, corresponding secondary air channel is provided with centrifugal blower, and the control method of described wall-hanging air conditioner includes
Following steps:
Judge whether currently received instruction is wind-guiding instruction；
The control module of air-conditioner receives control instruction, the instruction received is entered with the instruction catalogue being pre-stored in controller
Row comparison, to judge whether currently received instruction is wind-guiding instruction.It is of course also possible to by judging to connect according to signal intensity
Whether the instruction received is wind-guiding control instruction.
If so, centrifugal blower is opened, so that the connectivity part in described main air duct and described secondary air channel forms negative pressure.
In the present embodiment, secondary air channel is correspondingly arranged on centrifugal blower, when centrifugal blower works, by the air in secondary air channel
Discharge from secondary air outlet.Forming negative pressure in making secondary air channel, air enters secondary air channel from secondary air inlet 210, at secondary air inlet 210
Negative pressure is formed at neighbouring main air outlet 120.Thus the air-flow flowed out from main air outlet 120 is guided.
For the more preferable wind-guiding of air-conditioner, described secondary air channel includes secondary air channel and lower secondary air channel, and each secondary air channel is the most right
A centrifugal blower should be provided with；
The step of described unlatching centrifugal blower has and includes:
Open with centrifugal blower corresponding to described upper pair air channel and/or；
Open the centrifugal blower corresponding with described lower secondary air channel.
In the present embodiment, can according to the actual requirements, centrifugal blower that in unlatching, secondary air channel is corresponding or open with described
Centrifugal blower that lower secondary air channel is corresponding or simultaneously open the centrifugal blower that upper secondary air channel is corresponding with lower secondary air channel, i.e. can root
The quantity of wind-guiding position and wind guide component is selected according to actual demand.User is conducive to obtain effect of blowing more accurately.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every at this
Under the inventive concept of invention, utilize the equivalent structure transformation that description of the invention and accompanying drawing content are made, or directly/indirectly use
The technical field relevant at other is included in the scope of patent protection of the present invention.
