Abstract
The utility model provides a spiral pressurization wind wheel device and belongs to the field of parts of a smoke exhaust ventilator. The spiral pressurization wind wheel device comprises a cylindrical wind wheel which is disposed in a spiral case; the circular edge of the cylinder is provided with wind wheel blades arranged in an inclined manner; a pressurization wind wheel is disposed in the cylindrical wind wheel and comprises a circular base plate and blades, the blades being arranged on the surface of the circular base plate in an annular manner uniformly; and the axis of the round base plate is fixedly connected with a motor shaft. The spiral pressurization wind wheel device is capable of increasing negative pressure in the spiral case effectively and increasing axial air supply quantity of the spiral case, and enables wind flow to increase on the inner side of the radial wind wheel, thereby enabling wind discharge quantity of the spiral case to increase.
Description
Technical field
The utility model belongs to the range hood part field, and is especially relevant with a kind of spiral boosting wind wheel.
Background technique
At present, the structure of the wind wheel of the range hood of generally selling on the market is cylindrical wind wheel, the wind wheel blade that is obliquely installed is set on the cylindrical circular edges, the wind wheel center of circle is fixedly connected with motor shaft, the rotation of driven by motor wind wheel makes the inner negative pressure that forms of range hood, at present, how improving wind wheel efficiengy-increasing spiral case internal negative pressure becomes and puts the axe in the helve.
The model utility content
The purpose of this utility model will overcome defects exactly, and a kind of negative pressure that can improve in the spiral case is provided, and strengthens the device of the air output of spiral case, for this reason, the utility model by the following technical solutions:
The spiral boosting wind wheel, comprise cylindrical wind wheel, cylindrical wind wheel is installed in spiral case inside, the wind wheel blade that is obliquely installed is set on the cylindrical circular edges, it is characterized in that: in described wind wheel inside the supercharging wind wheel is set, this supercharging wind wheel comprises circular base plate and blade, and the blade annular is evenly distributed on the circular base plate surface, and the axle center of circular base plate is fixedly connected with motor shaft.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described blade is the semicircle arcuation.
Described blade can also be straight line shape.
Use the utility model can reach following beneficial effect: use the negative pressure in the impeller of booster meeting Effective Raise spiral case, the air inlet through hollow shaft amount of increase spiral case, and make the distinguished and admirable radially inboard of wind wheel that is added to, thus strengthen the air output of spiral case.
