Embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
The range hood of the embodiment of the present invention, as shown in Figs. 1-5, the range hood, includes annular spiral case
Body 1, and the air outlet 2 of the top side positioned at spiral case body 1, the air outlet 2 are a square outlet, on the air outlet 2
Equipped with outlet air cover body 3, outlet air cover body 3 is that section is circular outlet air cover body, for being circular smoke exhaust pipe with extraneous section
Connection, outlet air cover body 3 are equipped with one-way non-return valve 31.The air outlet 2 is equipped with wind deflector 4, which is arranged at outlet air
Inner peripheral the radially extending along air outlet 2 of mouth 2 so that the air outlet 2 forms a circular outlet.The spiral case body 1 wraps
Front face 11 and rear surface 12, and the ring wall 13 around the periphery of front and rear wall are included, the top side of ring wall 13 is equipped with outlet
Flange 14, forms air outlet 2 on outlet(discharge) flange 14.
The circular outlet and the section of outlet air cover body 3 match.In this way, can on the air outlet 2 of the range hood
It is circular outlet air cover body 3 directly to set section, therefore, can not have to set the conversion equipment from square towards circle conversion,
So that the height of range hood entirety is minimized, and overall volume reduces.
And the lower section of the wind deflector 4 of side is close to be equipped with volute tongue 5, volute tongue 5 and the ring wall of spiral case body 1 on air outlet 2
13, which are connected, is adjacent to, the shape of the volute tongue 5, and as shown in Fig. 3,4,5, the front end face 51 of volute tongue 5 is into the inside of spiral case body 1
Recessed arc, matches with the periphery of wind deflector 4, and the bottom surface 52 of volute tongue 5 be under convex curved surface, the i.e. bottom surface 52 section
It is arc-shaped, as shown in figure 4, be downward projection of arc, it is such to be shaped such that volute tongue 5 is downwardly convex at air outlet 2, it can subtract
The area of sudden change region at the air outlet 2 of small spiral case, so as to reduce vortex, reduces energy loss.And those skilled in the art
Also be understood that, have 5 side of spiral case wind deflector 4 can also omit, that is to say, that the spiral case 5 of the side of air outlet with
The wind deflector 4 of opposite side forms circular outlet together, is so omitted component, reduces cost.
And in the embodiment, 41 shape of top plane of the wind deflector 4 of air outlet opposite side is 2 side shape of air outlet
What is matched is arc-shaped, and the section of the horizontal direction formed below of wind deflector 4 is the inclined-plane 42 of arc, gradually towards spiral case body
1 inner wall is close, and the both sides of wind deflector 4 are mutually fixed with the front and back sides of spiral case body 1.
As shown in Figure 6,7, for the range hood another embodiment schematic diagram, in the embodiment, same spiral case
