Abstract
The utility model discloses a civil induced draught fan. The bottom of the shell of the blade chamber of the induced draught fan is semicircular or arc in shape; the upper part of the shell of the blade chamber is arranged outwards and open, and the opening of the upper part of the shell of the blade chamber is an open air outlet. A fan blade is eccentrically arranged in the shell; and on the shell, the wall of shell on the side opposite to the motor is a plane, and the place corresponding to the fan blade on the plane is open, and the opening is an open air inlet. A fixed support is arranged on the shell. When in installing, the open air inlet is arranged facing a flue and the open air outlet is arranged on the inner wall of the flue, and the inner wall at the port of the flue is better; an umbrella-shaped cap can be arranged above the open air outlet of the shell or on the top of the flue. The civil induced draught fan has the beneficial effects that, since the motor and other electric elements are all arranged on the outer wall of a chimney and keep away from a smoke duct, the work environment of the civil induced draught fan is improved fundamentally, and the maintenance and protection of the civil induced draught fan become more convenient.
Description
Technical field
The utility model relates to a kind of domestic guiding fan.
Background technique
Existing domestic guiding fan is mounted in directly over the chimney of roof all, thereby is subjected to smoke fire during its work and burns and can hardly be avoided, and usually can cause the damage of electric wiring and components and parts and can't normally use.Though therefore the economic loss that causes is also not very big, maintenance and service work but are cumbersome, the fine method that does not also address this problem at present.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of can make working environment be improved significantly domestic guiding fan design.
The technological scheme that the utility model adopted is the bottom semicircular in shape or the arc of this induced draught fan fan blade chamber housing, the outside diffusion open in top, its opening is that air-out is uncovered, draught fan impeller off-centre is contained in the housing, be plane shape with the opposing side shell wall of motor side on the housing, corresponding draught fan impeller place is also opened wide on it, and it is uncovered to be that air intake is uncovered.On housing, also be provided with fixed bearing, can also have 90 degree between the supporting surface of bearing and the housing to 135 degree angles.Air intake with this electric fan shell when use installing is uncovered facing to flue, and air-out is uncovered to be installed on the inwall of flue up, preferably is installed on the inwall at flue exit place.
Above the air intake of housing is uncovered, perhaps can also be provided with umbrella hat on the top of flue.
The beneficial effects of the utility model are because motor and electrical apparatus element all are arranged on the outer wall of chimney, avoided discharge flue, thereby its working environment have obtained the improvement of essence.And it is maintained and protect also more convenient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the plan view of Fig. 1
Fig. 3 is a use installation method schematic representation of the present utility model
Embodiment
Example 1
As shown in Figure 1 and Figure 2, the bottom semicircular in shape or the arc of this induced draught fan fan blade chamber housing 1, the outside diffusion open in top, its opening is air-out uncovered 5, draught fan impeller 6 off-centre are contained in the housing 1, side shell wall 2 relative with motor 4 ends on the housing 1 is a plane shape, and corresponding draught fan impeller 6 places are also opened wide on it, and it is uncovered to be air intake uncovered 3.On housing 1, also be provided with fixed bearing 8.Have the angle of 90 degree between the supporting surface of fixed bearing 8 and the housing 1, mounted induced draught fan appropriateness is leaned forward to 135 degree.
Air intake uncovered 3 with this electric fan shell 1 when using installation faces toward flue 7, and air-out uncovered 5 is installed on the inwall of flue 7 up, preferably is installed on the inwall at flue exit place.See Fig. 3.
Example 2
Above the air-out of housing 1 uncovered 5, perhaps also be provided with umbrella hat, because this design is simple especially, so this accompanying drawing omits on the top of flue 7.
Claims (3)
1, a kind of domestic guiding fan, the housing and the draught fan impeller that comprise the fan blade chamber, the bottom semicircular in shape or the arc that it is characterized in that this induced draught fan fan blade chamber housing (1), the outside diffusion open in top, its opening are air-out uncovered (5), and draught fan impeller (6) off-centre is contained in the housing (1), it is plane shape that housing (1) is gone up the side shell wall (2) relative with motor (4) end, corresponding draught fan impeller (6) is located also to open wide on it, and it is uncovered to be air intake uncovered (3), also is provided with fixed bearing (8) on housing (1).
