Abstract
The utility model provides a double wind wheel fume extractor which comprises a motor, a rotor shaft installed on the motor, a left spiral casing, a right spiral casing, a left wind wheel and a right wind wheel, wherein, the rotor shaft of the motor is penetrated out extendedly along the both sides of the motor, and the left wind wheel and the right wind wheel are correspondingly and fixedly installed at the left end and the right end of the rotor shaft. After adopting the technical proposal, the two wind wheels are symmetrically installed at the both sides of the motor, thereby ensuring the motor to be in the equilibrium state during the work, and the air suction opening of each wind wheel corresponds to a stove to suck air, the actual length of the single wind wheel can be shortened, therefore, the wind wheels have detachability within a limited space, and the easy disassembling and washing purpose is achieved.
Description
Technical field:
The utility model relates to the smoke exhaust ventilator technical field, and refer in particular to a kind of increase suction tolerance and reduce pneumatic noise, and the two wind wheel smoke exhaust ventilators of easily removable and washable formula.
Background technology:
Traditional smoke exhaust ventilator all is single wind wheel, corresponding motor has only a side to draw turning cylinder, the smoke exhaust ventilator of this structure is when work, because its asymmetry, increased wearing and tearing and noise that motor rotation axis holds, and two cooking stoves about generally stove and accessory is furnished with, the single suction air port of single wind wheel smoke exhaust ventilator can only be arranged between two cooking stoves, the exhausting effect is undesirable, owing to having only an inlet scoop so air-flow bigger through vapour lock and the pneumatic noise that the inlet scoop produces.In addition, existing spiral case all is that metal solder is one-body molded, the rectangular structure of its air outlet, when air outlet with after round check valve assembly is connected, the dead angle that is unfavorable for the air-flow high-speed motion is arranged in the spiral case, cause air movement to be obstructed, reduce suction tolerance and produce big noise.Also have, single wind wheel smoke exhaust ventilator is that to satisfy the length of its its wind wheel of suction tolerance longer, can't disassembly, cleaning after installing and using.
Summary of the invention:
The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, a kind of pair of wind wheel smoke exhaust ventilator to be provided.
For achieving the above object, the technical scheme that the utility model provides is: a kind of pair of wind wheel smoke exhaust ventilator, include motor, be installed in the armature spindle on the motor, left and right spiral case and left and right wind wheel, the rotor axial motor both sides extension of motor passes, and correspondence is fixed with left and right wind wheel on the two ends, the left and right sides of armature spindle.
Left and right spiral case is respectively equipped with the inlet scoop on the wind wheel correspondence position.
Become to flexibly connect between the composition surface of left and right spiral case.
The air outlet that is positioned at the spiral case top is for to carry out the transition to circular configuration gradually from rectangle.
After adopting technique scheme, by two wind wheels being installed in the bilateral symmetry of motor, be in poised state when making machine operation, and the corresponding cooking stove exhausting in the inlet scoop of each wind wheel, owing to adopt the double suction air port that the vapour lock that produces when air communication is crossed the inlet scoop is set, and the noise that air-flow produced obviously reduces, when suitably reducing power of motor, still can increase suction tolerance, save the energy and improved service behaviour.Because air outlet is for to carry out the transition to circular configuration gradually from rectangle, the dead angle of the air-flow high-speed motion in spiral case that can not exert an influence, therefore the windage and the noise of generation reduce greatly.Because adopt two wind wheel structures, the physical length of its single wind wheel can shorten, therefore wind wheel has detachability in limited space, reaches easily removable and washable purpose.
Description of drawings:
Fig. 1 is the three-dimensional exploded view of smoke exhaust ventilator of the present utility model.
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
As attached illustrated in figures 1 and 2, this pair of wind wheel smoke exhaust ventilator, include motor 1, be installed in the armature spindle 2 on the motor 1, a left side, right spiral case 3,4 and left, right wind wheel 5,6, extension passes the armature spindle 2 of motor 1 to motor 1 both sides, correspondence is fixed with a left side on the two ends, the left and right sides of armature spindle 2, right wind wheel 5,6, should a left side after smoke exhaust ventilator is installed, right wind wheel 5,6 inlet scoop 8.9 correspondences are in two cooking stove tops on the gas burner, the left side wind wheel 5 main left side cooking stoves of drawing, right wind wheel 6 main the right oil smoke that cooking stove produced of drawing, because double suction air port 8 is set, 9, increased the equivalent cross-sectional area of inlet scoop effectively, crossed vapour lock and the pneumatic noise that the inlet scoop produces when air communication and obviously reduce; Spiral case is made up of left and right spiral case 3,4, become to flexibly connect between them, this has just simplified the processing of mould greatly, spiral case adopts plastics to make, avoid adopting metal material to increase cost, the air outlet 7 that is positioned at the spiral case top is from the rectangular circular configuration that carries out the transition to gradually, the dead angle of the air-flow high-speed motion in spiral case of so just can eliminating the effects of the act.During disassembly, cleaning, revolve nut 10,11 and take off at 8,9 places in the inlet scoop, wind wheel 5,6 is unloaded from rotor axis of electric 2, and take out from inlet scoop 8,9 separately respectively.
