The air channel structure of American air-cooled ducted air conditioner
Technical field
The utility model relates to air-conditioning manufacturing technology field, is specifically related to a kind of air channel structure of American air-cooled ducted air conditioner.
Background technology
The air channel of general American air-cooled ducted air conditioner is made up of tuyere structure and centrifugal metal wind wheel, and tuyere structure by a left side, air channel, the right baffle plate in air channel, gripper shoe, overhead gage, lower baffle plate and automatically controlled installing plate etc. totally 6 structural members form, its quantity is more.In process of production, needs assemble into an assembly to each structural member through screw earlier, refill to be fitted on the fuselage; Assembling process is complicated, and efficiency of assembling is low, and cost is higher.In addition, complicated structure has directly caused the air-cooled ducted air conditioner fuselage size bigger than normal, thereby needs corresponding bigger installation and spatial accommodation, and the part maisonette can't be installed and used owing to be subject to the space size, has influenced popularizing and development of this type of air conditioner room unit.
The utility model content
The purpose of the utility model is to consider the problems referred to above, and tuyere structure is optimized, and simplifies the structure and the quantity of tuyere structure spare, and assembling is simple, the air channel structure of the American air-cooled ducted air conditioner of the size of reduction fuselage.
American air-cooled ducted air conditioner air channel structure by this purpose design comprises automatically controlled installing plate and centrifugal metal wind wheel; It is characterized in that also comprising the wind wheel fixed head, on said wind wheel fixed head, be provided with the air port; One side of said automatically controlled installing plate is installed on the wind wheel fixed head, and the opposite side support is on centrifugal metal wind wheel; The air outlet of said centrifugal metal wind wheel is installed on the wind wheel fixed head, and the air outlet of centrifugal metal wind wheel is corresponding with the air port and communicate.
The both sides that on said wind wheel fixed head, are positioned at the air port respectively are provided with a holddown groove; Be positioned on the wind wheel fixed head air port below be provided with the wind wheel limiting plate, the relevant position on the wind wheel fixed head is provided with two fixed heads and is used for being connected with automatically controlled installing plate fixing a plurality of screw holes; The right and left that on said centrifugal metal wind wheel, is positioned at air outlet is respectively equipped with the guide flange bar; Be positioned on the centrifugal metal wind wheel air outlet above be provided with mounting flange; Said guide flange bar is arranged in holddown groove; Said mounting flange is fixed through screw and two fixed heads, and the below support of centrifugal metal wind wheel is on the wind wheel limiting plate.
The utility model advantage compared with prior art is: on the basis that does not influence the air-cooled ducted air conditioner overall performance; Be optimized to 2 structural members to 6 structural members of tuyere structure; Reduced the screw number of connection in a large number; The product efficiency of assembling is significantly improved, and reduced cost, and product reliability also is much improved.On centrifugal metal wind wheel, made full use of the space in the air-cooled ducted air conditioner casing to automatically controlled installing plate support, made the fuselage reduced height surpass 10%, length dimension shortens above 20%, thereby has saved installing space greatly.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
To shown in Figure 3, a kind of American air-cooled ducted air conditioner air channel structure comprises automatically controlled installing plate 2 and centrifugal metal wind wheel 3 like Fig. 1; The utility model characteristics are also to comprise wind wheel fixed head 1, on said wind wheel fixed head 1, are provided with air port 11; One side of said automatically controlled installing plate 2 is installed on the wind wheel fixed head 1, and the opposite side support is on centrifugal metal wind wheel 3; The air outlet of said centrifugal metal wind wheel 3 is installed on the wind wheel fixed head 1, and the air outlet of centrifugal metal wind wheel 3 and air port 11 are corresponding and communicate.
In the present embodiment; The both sides that on said wind wheel fixed head 1, are positioned at air port 11 respectively are provided with a holddown groove 12; Be positioned on the wind wheel fixed head 1 air port 11 below be provided with wind wheel limiting plate 13, the relevant position on wind wheel fixed head 1 is provided with two fixed heads 14 and is used for being connected with automatically controlled installing plate 2 fixing a plurality of screw holes 15; The right and left that on said centrifugal metal wind wheel 3, is positioned at air outlet is respectively equipped with guide flange bar 31; Be positioned on the centrifugal metal wind wheel 3 air outlet above be provided with mounting flange 32; Said guide flange bar 31 is arranged in holddown groove 12; Said mounting flange 32 is fixing through screw and two fixed heads 14, and the below support of centrifugal metal wind wheel 3 is on wind wheel limiting plate 13.
During assembling, the holddown groove 12 of the guide flange bar 31 on the centrifugal metal wind wheel 3 on wind wheel fixed head 1 inserts downwards in the holddown grooves 12, and till the air outlet below of centrifugal metal wind wheel 3 support was to the wind wheel limiting plate 3, centrifugal metal wind wheel 3 was in place; At this moment, the mounting flange 32 on the centrifugal metal wind wheel 3 contacts with two fixed heads 14 on the wind wheel fixed head 1, and is through screw that mounting flange 32 and fixed head 14 is fastening again, promptly accomplished the mount between wind wheel fixed head 1 and the centrifugal metal wind wheel 3.Because the pcb board installed surface support of automatically controlled installing plate 2 on the spiral case of centrifugal metal wind wheel 3, makes spiral case can bear the weight of components and parts such as a part of automatically controlled installing plate 2 and pcb board, has improved product reliability.Automatically controlled components and parts setting is installed in the top of centrifugal metal wind wheel 3, has made full use of the space in the air-cooled ducted air conditioner casing, makes the fuselage reduced height surpass 10%, and length dimension shortens above 20%, thereby has greatly saved installing space.
