220 tangent line and the angle of circular end face 101 are 22 °.
It should be noted that in the present embodiment, along the circumferential direction of spiral case ontology 100,200 arc transition of changeover portion.
Changeover portion 200 is the shell-like structure for the protrusion that annular extends, in the axis direction along spiral case ontology 100 and along spiral case ontology 100
Radial direction, the opening of changeover portion 200 is gradually increased, so that make the first end 210 of changeover portion 200 (can be remote here
Distalmost end from spiral case air outlet) tangent line and the angle of circular end face 101 be 5 °, the second end 220 of 200 outer wall of changeover portion
Tangent line and the angle of circular end face 101 are 22 °.
From first end 210 to second end 220, the height of changeover portion 200 successively increases and arc transition.Such design is not
But become larger with making the air duct gradual change of spiral case;Spiral case is also set to be provided with the transition of arc, the wind that centrifugal blower generates can take advantage of a situation arc
The guidance of shape changeover portion 200 smoothly blows to air outlet.It has so ensured sufficient air quantity, has also avoided turbulent flow and turbulent flow
Occur, realizes the technical effect of smooth outlet air.
Further, in the present embodiment, above-mentioned centrifugal blower volute 10 further includes chimney fan 300;Chimney fan 300 and mistake
The second end 220 for crossing section 200 connects;The junction of chimney fan 300 and changeover portion 200 is arc or polygon.
In this way, the wind that the arc or polygonal design of junction enable to blower to generate can after changeover portion 200
Swimmingly connect.
Further, in the present embodiment, above-mentioned centrifugal blower volute 10 further includes the extended segment of the smooth tubular of inner wall
400;The second end 220 of changeover portion 200 is connect by extended segment 400 with chimney fan 300;The company of chimney fan 300 and extended segment 400
The section for meeting place is arc or polygon.
So ensure that the air from blower smooth can unhinderedly be discharged from chimney fan 300.
Optionally, the cross sectional shape of chimney fan 300 is annular or polygon.It is suitable when such shape has ensured outlet air
Freely, the obstruction to air is reduced.Optionally, chimney fan 300 has the opening of radial direction, and the opening is along chimney fan 300
Axis direction extends.It may also be seen that being provided with multiple movably flabellums (showing in figure unlabeled) on air duct 300
To adjust the direction of outlet air.
The present embodiment of the invention also provides a kind of air conditioner 20, and air conditioner 20 includes above-mentioned centrifugal blower volute 10.
Air conditioner 20 include above-mentioned centrifugal blower volute 10, therefore have centrifugal blower volute 10 all beneficial to imitate
Fruit.The centrifugal blower volute 10 of air conditioner 20 greatly reduces air in the resistance of fan air channel, improves air quantity and air-supply
Distance keeps complete machine air conditioner 20 more comfortable.
Specifically, can be seen that air conditioner 20 from Fig. 3 and Fig. 4 includes two centrifuges and two chimney fans 300, from
Scheming and chimney fan 300 correspond.Further, two centrifuges are alternately superimposed, and two chimney fans 300 are mutual
Connection integrates, so to save installation space.
It can also be seen that the extended segment 400 of the more superposed centrifuge in extended segment 400 positioned at the centrifuge of bottom
Long, the extended segment 400 of different length ensure that the air from centrifuge can smoothly be discharged from chimney fan 300.
The technical solution of the embodiment of the present invention is at least had the following advantages and beneficial effects:
Centrifugal blower volute 10 includes spiral case ontology 100 and changeover portion 200.The first end 210 of changeover portion 200 is located at spiral case
The side of air outlet on ontology 100 far from spiral case ontology 100, second end 220 are located at the air outlet close to spiral case ontology 100
Side, while from first end 210 to second end 220, the inner wall section opening of changeover portion 200 is gradually increased.It allowed in this way
The smooth gradual transition of section 200 is crossed, i.e., the outlet air from spiral case ontology 100 can be smoothly discharged by changeover portion 200, make to have leisure
Gas is greatly reduced in the resistance of fan air channel, the form using spiral case end face with gradual change, effective solution centrifugal blower volute
The unsmooth problem of 10 air-supplies.
Air conditioner 20 includes above-mentioned centrifugal blower volute 10.Air conditioner 20 makes air significant in the resistance of fan air channel
Reduce, improve air quantity and air supplying distance, keeps complete machine air conditioner 20 more comfortable.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
