The erosion that is subject to flue gas for the motor that overcomes existing domestic guiding fan and running part thereof; service life is short; the deficiency that work quality is relatively poor; the utility model provides a kind of side-mounted domestic guiding fan that motor is contained in air inducing frame side; this type is because motor is installed in the side of air inducing frame; and motor shaft sheath and upper and lower protective cover and cooling device are voluntarily arranged, therefore can effectively reduce the erosion of high temperature, high humidity and harmful smoke to motor.
2. technical scheme
The technical scheme that its technical problem that solves the utility model adopts is: by air inducing frame, blower fan, ventilating fan, down protective cover, go up the side-mounted domestic guiding fan that protective cover is formed; its special character is to be provided with protective cover down on the wall of air inducing frame one side; in the following protective cover motor is housed, air inducing fan, blower fan and ventilating fan are housed on motor shaft.
Solve in the technical scheme that its technical problem adopts at the utility model; on the sidewall that is arranged on the air inducing frame that following protective cover and the motor that is mounted in it tilt; when an end that will have air inducing fan is made as when tilting downwards; the longitudinal center line of its motor and horizontal upward angle are 80 °-10 °; when an end that will have air inducing fan is made as when tilting upward, the longitudinal center line of its motor is 10 °-80 ° with horizontal time angle.
The utility model is in the technical scheme that adopted of its technical problem of solution; around reaching, the top of air inducing frame is provided with several exhaust smoke holes; on the wall of last protective cover and following protective cover, be respectively equipped with several fresh air inlets and vent, be provided with the tubular motor sheath shaft in the centre of following protective cover bottom surface.
The utility model is in the technical scheme that adopted of its technical problem of solution, and the air inducing fan is contained in motor shaft bottom, and ventilating fan and blower fan are installed in down respectively on the motor shaft between protective cover and motor and motor and the last protective cover.
3. beneficial effect
The beneficial effects of the utility model are effectively to prevent or reduce the erosion of the flue gas of high temperature, high humidity to motor, and have reduced the exhaust resistance of flue gas, and blower effect is improved.Simultaneously, the heat that cold air has produced when having taken away machine operation during by ventilating duct has improved the working environment of motor.

Among the figure: 1. motor shaft; 2. air inducing is fanned; 3. motor shaft sheath; 4. air inducing frame; 5. exhaust smoke hole; 6. play protective cover; 7. ventilating fan; 8. motor; 9. blower fan; 10. go up protective cover; 11. ventilating duct; 12. vent; 13. fresh air inlet; 14. horizontal line; 15. longitudinal center line.
The specific embodiment
In Fig. 1; following protective cover (6) is located on the wall of air inducing frame (4) one sides; be fixed with motor (8) in the following protective cover (6); the air inducing that is equipped with bottom of motor shaft (1) is fanned (2); on the motor shaft (1) between motor (8) and the following protective cover (6), ventilating fan (7) is housed, on the motor shaft (1) between motor (8) and the last protective cover (10), blower fan (9) is housed.The top of air inducing frame (4) be provided with several exhaust smoke holes (5) all around, be provided with tubular motor sheath shaft (3) at the center of protective cover (6) bottom surface down.
On the sidewall that is arranged on air inducing frame (4) that following protective cover (6) and the motor (8) that is mounted in it tilt; when an end that will have air inducing fan (2) is made as when tilting downwards; the longitudinal center line of its motor and horizontal upward angle are 80 °-10 °; when an end that will have air inducing fan (2) is made as when tilting upward, its motor longitudinal center line is 10 °-80 ° with horizontal time angle.Because the center of motor (8) from air inducing frame (4) moved on on the sidewall, like this, not only reduced exhaust resistance but also reduced the chance that flue gas is invaded motor.
After connecting power supply, motor (8) drives the rotation at a high speed simultaneously of air inducing fan (2), ventilating fan (7) and blower fan (9) by motor shaft (1).Outside being located at air inducing frame (4) top and exhaust smoke hole all around (5) discharge machine, smoke tube mouth produces negative pressure to air in the chimney under the effect of air inducing fan (2), and the flue gas in the cooking stove flows through to replenish, and the cooking stove mouth enters fresh air again, makes full combustion of fuel.Suck → get rid of the order that enters fresh air in flue gas → cooking stove again through flue gas like this, go round and begin again, finish the air inducing operation.
In Fig. 2-Fig. 4, be respectively equipped with several vents (12), fresh air inlet (13) and ventilating duct (11) on the wall of following protective cover (6) and last protective cover (10).During work; under the effect of blower fan (9) and ventilating fan (7); after cold air enters ventilating duct (11) between motor and the upper and lower protective cover from all fresh air inlets (13); outside all vents (12) discharge machine; and the heat that produces when having taken away machine operation; cool off motor, made motor keep good working environment, prolonged its service life.
