Specific embodiment
In conjunction with referring to FIG. 1 to FIG. 4, according to an embodiment of the invention, dual channel spiral case includes the first training wall 1, the
Two training walls 2 and dividing walls 3, dividing walls 3 are arranged between the first training wall 1 and the second training wall 2, the outlet air end of dividing walls 3
End is provided with the first bulkhead 4 and the second bulkhead 5, and first runner 6 is formed between the first training wall 1, dividing walls 3 and the first bulkhead 4,
Second flow channel 7 is formed between second training wall 2, dividing walls 3 and the second bulkhead 5.
Since dual channel spiral case shunts the outlet air of blower by dividing walls 3, blower outlet air is then enabled to divide
It is not flowed out from first runner 6 and second flow channel 7, realizes dual channel outlet air, therefore by using the dual channel spiral case, it is only necessary to one
A spiral case and a blower can realize the outlet air up and down of air conditioner, and structure is simple, and cost is relatively low, and occupied space compared with
It is small, it can be realized the densification of air conditioner structure.
Preferably, first runner 6 and second flow channel 7 are located at the radial outside and radially inner side of dual channel spiral case, make
Have leisure and recalls wind and can be formed radially outlet air level in dual channel spiral case along first runner 6 and second flow channel 7, it is more convenient
The structure for forming outlet air up and down, is easy to implement the outlet air up and down of air conditioner.
The air outlet of first runner 6 is located at below the air outlet of second flow channel 7, and the air outlet of first runner 6, which is formed down, to be gone out
The air outlet in air port, second flow channel 7 forms air outlet.It enables to the dual channel of single spiral case to design with this configuration to realize
Upper and lower distribution air-supply, air-supply can cover entire human body, promote client's comfort.
The axial ends of first training wall 1 and the second training wall 2 is provided with spiral case cover board 9, can be by 1 He of the first training wall
The closure of openings at 2 both ends of the second training wall enables air conditioner air-out along first-class to form the runner of all round closure
Road 6 and second flow channel 7 are advanced, and are avoided that air leakage phenomena occurs, are improved outlet air efficiency.
In the present embodiment, spiral case has dual channel, respectively first runner 6 and second flow channel 7, and each runner has phase
The volute tongue answered, respectively the first volute tongue 12 and the second volute tongue 13, wherein the first volute tongue 12 is formed in the air intake of dividing walls 3, the
Two volute tongues are formed at the link position of the first training wall 1 and the second training wall 2, have different spiral cases to avoid in different runners,
Different air outlets, the respectively upper outlet air of the lower air outlet of first runner 6 and second flow channel 7 are provided on different runners
Mouthful, to realize the outlet air of different directions.
According to an embodiment of the invention, air channel structure includes above-mentioned dual channel spiral case.
Assembling chamber is formed in first training wall 1, air channel structure further includes centrifugal blower 8, and centrifugal blower 8 is arranged in wind
In machine installation cavity.
Dividing the first shunt duct of formation, dividing walls 3 and the first water conservancy diversion at wind position between dividing walls 3 and centrifugal blower 8
Dividing the second shunt duct of formation at wind position between wall 1.After air is flowed out out of centrifugal blower 8, in the first snail of dividing walls 3
Carry out a point wind at tongue 12, a part enters in first runner 6 through the first shunt duct, another part through the second shunt duct into
Enter into second flow channel 7, a point character and conduct for 8 outlet air of centrifugal blower is made in completion.
Preferably, centrifugal blower 8 is double-suction centrifugal fan, is respectively arranged with air inlet in the axial ends of dual channel spiral case
10.By using double-suction centrifugal fan, the cost of indoor unit of air conditioning cabinet can be reduced, solves the problems, such as insufficient space, is improved
On the one hand the working efficiency of centrifugal blower is to increase blower utilization efficiency, improve air quantity, on the other hand, improves the stream in room
Dynamic range of DO, enhances indoor comfort.In the present embodiment, double-suction centrifugal fan includes double sucking centrifugal wind blade and driving electricity
Machine namely the air channel structure of the application only need a centrifugation blade and a driving motor that can complete to be distributed out up and down
Wind, therefore can be effectively reduced cost, space hold is reduced, manufacturing procedure is reduced.
Under the acting of impeller of double-suction centrifugal fan, air-flow is entered the wind from the two sides of dual channel spiral case,.
It include double sucking centrifugal wind blade, dual channel spiral case, driving motor in above-mentioned air channel structure, three is produced by driving motor
Lively power makes centrifugation blade rotate to form negative pressuren zone, and air-flow enters in centrifugation blade through two sides heat exchanger 11, in dual channel spiral case
Then interior diffusion is distinguished upward air outlet under the guiding of the first runner of spiral case 6 and second flow channel 7, diffusion action and is gone out down
Air port distribution air-supply realizes distributed air-supply up and down, improves indoor comfort.Spiral case cover board 9 seals entire air duct, in addition to
Except the air inlet 10 of the left and right sides, so as to reduce the noise that leaks out, outlet air efficiency is improved.
In first runner 6, air-flow accelerates outflow from double-suction centrifugal fan, in the helix training wall of first runner 6
Downward air outlet flowing, prevents air-flow from returning in first runner 6 under the action of the first volute tongue 12 under the water conservancy diversion diffusion action in face.
In second flow channel 7, air-flow accelerates outflow from double salary centrifugal blower, in the helix training wall of first runner 6
Upward air outlet flowing, prevents air-flow from returning in second flow channel 7 under the action of the second volute tongue 13 under the water conservancy diversion diffusion action in face.
According to an embodiment of the invention, air conditioner includes air channel structure, which is above-mentioned air channel structure.
Preferably, when the axial ends of dual channel spiral case is respectively arranged with air inlet 10, go out to distinguish in air inlet 10
It is provided with heat exchanger 11.
Since the centrifugal blower of the application is entered the wind using two sides double suction, indoor air-flow is allowed to flow from room two sides, and it is upper
Lower outlet air forms the circulating current of packaging type in a room, further improves room comfort.Meanwhile it is indoor improving
On the basis of machine comfort and performance, a motor is shared by double sucking centrifugal wind blade, a dual channel spiral case, reduce motor,
Spiral case quantity reduces indoor unit cost.
