Abstract
Unlike available technology, which reduces noise through reducing motor power or placing the ventilator outdoor, the present invention designs a low-noise, low power consumption, high-efficiency thin kitchen ventilator by reducing noise source. The said kitchen ventilator is easy to mount and demount for cleaning, and has large sucking force, high purification rate and beautiful shape.
Description
The present invention relates to a kind of household smoke exhaust ventilator.
In existing technology, no matter be suspension type smoke exhaust ventilator or wall-hanging smoke exhaust ventilator, its motor all is that axle is rotating, draught fan impeller is fixed on rotation thereupon on the motor shaft, and motor is fixed on the casing of smoke exhaust ventilator.
This motor is fixed on the mounting means on the casing, make that the smoke exhaust ventilator noise is big, gauge is also big, because noise derives from vibration, the balancing processing of impeller can not be accomplished absolute equilibrium in producing smoke exhaust ventilator blower fan process, blower fan rotary blade vibration unavoidably always like this, motor is again to be fixed on the casing, drives shell like this and vibrates together and make casing produce speaker effect.Noise is bigger.
Reducing noise at present has two kinds of schemes, and the one, reduce power of motor, the 2nd, adopt the mode of blower fan away from human body.As application number is 91105335.2 wall type oil vapour extractors, this patent disclosure a kind of exhaust blower can be mounted freely on outside window or on the skylight, and Cooker hood is installed facing to the frying pan wall-attaching type, the part has solved noise problem like this.But in the middle of Cooker hood and the exhaust blower connecting pipe must be arranged in this mode, must increase resistance of ducting loss like this, power of motor increases, and cost increases, and installs inconvenient, also not attractive in appearance.And this mode that abates the noise is not from solving in essence, but room noise is become outdoor noise, contaminated environment.
The objective of the invention is to avoid above-mentioned technical deficiency part, and a kind of low noise, low-power consumption, high efficiency, slim smoke extractor are provided.
Design of the present invention is: start with from reducing noise source, at first select the low noise motor for use and select multiple wing low noise centrifugal fan for use, motor shaft is fixed on the ring flange.And fixing by ring flange and body of wall (or firm building), electric machine casing and rotary blade are fixed.Draught fan impeller rotates with electric machine casing, because the hub disk of impeller directly is fixed on the motor casing, has saved the impeller reel, save material, reduced cost, the casing of motor has played the effect of big reel to the impeller hub disk simultaneously, improve the rigidity of impeller hub disk, reduced the generation of noise.The motor axial dimension dwindles, and makes the smoke exhaust ventilator shell make the slim possibility that becomes.
Taking to select a kind of air-foil fan that can satisfy required flow of smoke exhaust ventilator and pressure parameter aspect the efficient that improves complete machine, when air inlet is installed, requiring air inlet to insert in the impeller, and certain interval is radially being arranged.In the appearance design of casing, considered that from aesthstic angle the length of casing and wide proportionate relationship are substantially:
L/B＝(1＋0.61B)
In the formula: L is the overall width size of casing
B is the high size of the gabarit of casing
0.618 optimization coefficient
The present invention will be further described below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the structure chart of the embodiment of the invention
Fig. 2 is the front appearance figure of the embodiment of the invention
Fig. 3 is an embodiment of the invention scheme of installation one
Fig. 4 is an embodiment of the invention scheme of installation two
Among the figure: 1. draught fan impeller 2. motor casings 3. end face flanges 4. volute of blower 5. air outlets 6. unidirectional 7. casing front panels, 8. air inlets, 9. oil collection boxes, 10. automatically controlled part 11. Oil Guide fins 12. casing bottom surface Oil Guide fins 13. volute of blower oil leaking holes 14. motor shaft 15. cabinet rear panels, 16. set bolts, 17. bodies of wall (or firm building) that cut down.
As shown in Figure 1, motor shaft 2 is fixed on the ring flange 3, and ring flange 3 is fastened on the wall and separates with cabinet rear panel 15, and cabinet rear panel 15 is fixing in addition to have reduced noise on the wall like this, and it is also convenient to unpick and wash.Air inlet 8 is fixed on the spiral case 4, and oil collection box 9 is plugged on casing front panel 7 following (as shown in Figure 2), and there is both ends high, middle low in the Oil Guide fin front panel below, and the minimum point below is facing to casing bottom surface Oil Guide fin 12.Automatically controlled part 10 is installed on the casing front panel 7.
Among Fig. 3, provided a kind of embodiment of the invention scheme of installation, motor shaft 14 fixedly fuses with end face flange 3, and is fixed on the body of wall (or firm building) 17 by flange.
Fig. 4 has provided another kind of embodiment of the invention scheme of installation, and motor shaft 14 is fixed flange and cabinet rear panel 15 with set bolt 16 after fixing with flange with body of wall (or firm building) 17.
Claims (4)
- One kind by motor, impeller, spiral case, air inlet, unidirectionally cut down, household smoke exhaust ventilator that automatically controlled part, oil collection box, casing etc. are formed is characterized by: fix a flange on the motor shaft, be fixed on the body of wall (or firm building) by flange, the motor casing rotation, impeller is fixed on the motor casing and with motor casing and rotates, motor is selected the low noise motor for use, exhaust blower selects for use multiple wing low noise centrifugal fan, air inlet to insert in the impeller, and radially leaving certain interval, because axial dimension dwindles, casing can be made the book molded dimension.
- 2. smoke exhaust ventilator according to claim 1 is characterized by: cabinet can be made the partial installation that do not fuse with motor as shown in Figure 3, or the installation form that connects together with flange, cabinet rear panel and body of wall (or firm building), as shown in Figure 4, convenient disassembly reduces vibration like this.
- 3. smoke exhaust ventilator according to claim 1 is characterized by: there are a two ends height, middle low, minimum point below in case front panel below facing to tank floor Oil Guide fin, makes the greasy dirt on its panel flow to oil collection box.
- 4. its characteristic of smoke exhaust ventilator according to claim 1 is: oil-guide device is arranged on the oil collection box.
