Abstract
The utility model discloses a bidirectional fan for sucking air and discharging foul gas, belonging to a device for discharging foul gas in kitchens. A motor and a blade are arranged in the shell body of the utility model. One end of the shell body is connected with a foul gas discharging pipe, and the other end of the shell body is uniformly provided with fixed leaves and is movably sheathed with a regulating sleeve. Movable leaves are uniformly arranged on the regulating sleeve. One side of the shell body is communicated with an air inlet pipe whose wall is provided with an air inlet hole. An adjustable air inlet passage is sheathed on the air inlet pipe, and the end of the air inlet pipe is provided with a plugging block. The utility model has the advantages of convenience, practicability and good foul gas discharging effect.
Description
The utility model relates to a kind of bidirection air intake blowdown fan, belongs to the kitchen bad air discharging device.
At present, the blowdown fan that the kitchen is commonly used, a kind of is ventilating fan, it generally is installed on the window, owing to transport out of kitchen range, filth-discharging effect is bad; Another kind is a smoke exhaust ventilator, and it generally is installed in the top of kitchen range, and the oil smoke filth-discharging effect during to cooking is good, but still not good enough to the dirty gas emission effect at indoor other position, and volume is big, and it is attractive in appearance to influence the kitchen.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of bidirection air intake blowdown fan is provided, and it both can get rid of the oil smoke at kitchen range position, can get rid of the dirty gas at other position again, and was convenient and practical.
The purpose of this utility model is achieved in that it comprises housing, motor, blade, blow-off pipe, and housing one end is connected with blow-off pipe, and the other end evenly is provided with fixedly leaf fan, and is movably installed with regulating sleeve, evenly is provided with movable leaf fan on the regulating sleeve; Housing one side is communicated with air inlet pipe, and the wall of air inlet pipe is provided with air admission hole, is set with variable geometry inlet on it, and sprue is installed in the end of air inlet pipe.
Compared with prior art, advantage of the present utility model is that it can two-way blowdown, promptly as required can be from housing one end blowdown, also can be from the variable geometry inlet blowdown, and convenient and practical, it is good that fruit is put in blowdown.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A of the present utility model is to view.
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
Motor (4) and blade (3) are installed in the housing of the present utility model (2), housing (2) one ends are connected with blow-off pipe (5), the other end evenly is provided with fixedly leaf fan (11), and is movably installed with regulating sleeve (1), evenly is provided with movable leaf fan (12) on the regulating sleeve (1); Housing (2) one sides are communicated with air inlet pipe (10), and the wall of air inlet pipe (10) is provided with air admission hole (8), are set with variable geometry inlet (6) on it, and sprue (9) is installed in the end of air inlet pipe.The wall of variable geometry inlet (6) is provided with air admission hole (7), and fixedly to fan (12) quantity identical for leaf fan (11) and movable leaf.
Start motor (4), blade (3) rotation just can blowdown.When needs are got rid of the dirty gas of housing (2) end portion, rotary regulating sleeve (11), make movable leaf fan (12) and fixing leaf on it often fan (11) corresponding, rotate variable geometry inlet (6) simultaneously, make it miss air admission hole (8) on air inlet pipe (10) wall, it is shut get final product, at this moment, dirty gas directly enters housing (2) from housing (2) end and discharges through blow-off pipe (5); When needs are got rid of the dirty gas at variable geometry inlet (6) position, rotary regulating sleeve (1), make movable leaf fan (12) and fixedly leaf fan (11) is staggered, just closure casing (2) end, rotate variable geometry inlet (6) simultaneously, make itself and corresponding the getting final product of air admission hole (8), at this moment, dirty gas enters variable geometry inlet (6) from variable geometry inlet (6) port and air admission hole (7), discharges through air admission hole (8), air inlet pipe (10), housing (2), blow-off pipe (5).The utility model is easy to use, and filth-discharging effect is good.
