Abstract
The utility model relates to a two-stage axial-flow cooking fume exhauster, which is used for exhausting the cooking fume in the kitchen. Because the utility model adopts a two-stage axial-flow fan, under the condition of sufficient pressure, the flow quantity is increased largely, the size is reduced, and the exhaust effect of the utility model is increased.
Description
The utility model relates to a kind of exhaustor for kitchen, and the flow that particularly a kind of two-stage axial flow blower constitutes is bigger, the smoke exhaust ventilator that pressure is enough, volume is little.
Existing smoke exhaust ventilator adopts centrifugal blower and does not adopt axial flow blower, and this mainly is to consider that the pressure coefficient of centrifugal blower is bigger than axial flow blower; But centrifugal blower is except the bigger shortcoming of noise, and main deficiency is that discharge coefficient is little, and the suction effect of the smoke exhaust ventilator of this just feasible employing centrifugal blower is bad.Existing be subjected to the restriction of smoke exhaust ventilator volume, rotating speed and noise by improving way that power of motor increases the smoke exhaust ventilator flow; And the way of seeking effective oil smoke shield cover owing to do not improve the flow of smoke exhaust ventilator, can not really improve suction effect.
The utility model attempts to provide a kind of smoke exhaust ventilator, is guaranteeing under enough pressure condition bigger flow is arranged, and the less smoke exhaust ventilator of volume own.
The technical solution of the utility model is: utilize the big advantage of axial flow blower discharge coefficient, being connected by the two-stage axial flow blower constitutes the blower fan of smoke exhaust ventilator, overcomes the little shortcoming of axial flow fan pressure coefficient.Utilize two axial flow fan vane wheels to be installed in series, relatively rotate with respect to each other, promptly to the axial flow rotary blower fan as the smoke exhaust ventilator blower fan, casing is cylindrical, additional any shield cover, the oil collector sump tank that current collector is installed and constitutes in import department by oil collecting ring, oil-deflecting rod and Sheng oil bowl.Smoke exhaust ventilator is fixing on the wall by U type support.The blower fan of the utility model smoke exhaust ventilator also can be made of two homodromal impellers of a driven by motor.
It is 28cm that the utility model smoke exhaust ventilator adopts the impeller diameter worker, when motor speed is 1450rpm, pressure can reach 80Pa, the stream 18m that weighs
3/ min; The zone radius of effectively taking out reaches 30cm, reaches fully to guarantee enough pressure, and big flow, volume is little, suction effect is good purpose are arranged.
Below in conjunction with accompanying drawing technical solutions of the utility model are described further.
Accompanying drawing is the cutaway view of the utility model smoke exhaust ventilator.
Embodiment: as shown in drawings, motor (2), (3) are fixed on the columniform casing (1) by fixed head (4), (5) respectively, and impeller (6), (7) relatively rotate respectively.Smoke exhaust ventilator import department installs current collector (10) and oil collecting ring (8), oil-deflecting rod (9), contains the oil collector sump tank that oil bowl (11) constitutes, rotate isolated oil droplet at a high speed by impeller (6), (7) and flow to oil collecting ring (8) along casing (1) inwall, flow in the oil-collecting bowl (11) by oil-deflecting rod (9) again, oil-collecting bowl (11) plays the effect of radome fairing simultaneously, and smoke exhaust ventilator is fixing on the wall by a U type frame.
Claims (1)
1. kitchen smoke exhaust ventilator, form by casing, blower fan, oil collector sump tank, it is characterized in that: casing is cylindrical, blower fan is the convection rotary type blower fan or is made of two impellers of same driven by motor, along oil collecting ring (8) is arranged, oil collecting ring (8) is with diversion rod (9) and contain the oil collector sump tank that oil bowl (11) constitutes smoke exhaust ventilator in the rectifier at air inlet place (10).
