Abstract
The utility model discloses a range hood fan unit structure with a pressure stabilizing function, which comprises a volute casing and an impeller. The volute casing is provided with an air outlet, and a chamfer structure inclined inwards is arranged at the air outlet and on the end surface of at least one side of the volute casing along the axial direction of the impeller. The range hood fan unit structure effectively reduces vortex of the air outlet of a fan unit, keeps pressure of the air outlet of the fan unit and reduces pressure loss of the air outlet of the fan unit.
Description
Technical field
The utility model relates to a kind of range hood, particularly a kind of range hood air unit structure with pressure stabilization function.
Background technique
At present, the blower fan group volute width of range hood is bigger than impeller width, cause when the high velocity air that impeller comes out flows into volute, will producing bigger sudden enlargement loss, and the easiest turbulent flow and the vortex phenomenon of producing in the volute outlet port.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of range hood air unit structure with pressure stabilization function, reduced the eddy current of blower fan group exhaust outlet and can keep blower fan group exhaust outlet pressure after using this range hood air unit structure, reduced the exhaust outlet pressure loss with pressure stabilization function.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of range hood air unit structure with pressure stabilization function, comprise volute and impeller, volute is provided with exhaust outlet, is positioned at exhaust outlet place along impeller shaft at least one side end face at volute and is provided with intilted chamfering structure.
As further improvement of the utility model, be positioned at exhaust outlet place along impeller shaft to the both sides end face at volute and be equipped with intilted chamfering structure.
As further improvement of the utility model, the chamfering structure on the described volute is for facing chamfering directly.
As further improvement of the utility model, chamfering structure madial wall on the described volute and volute madial wall angle are 100 °-170 °.
As further improvement of the utility model, the chamfering structure on the described volute is the cambered surface chamfering.
As further improvement of the utility model, the radius of arc of the chamfering structure cambered surface on the volute is 5mm-200mm.
As further improvement of the utility model, described single chamfering structure is 10mm-150mm along the width of impeller axial direction.
Useful technique effect of the present utility model is: the utility model is provided with intilted chamfering structure by being positioned at the exhaust outlet place at volute along the impeller axial end, effectively reduced the eddy current of blower fan group exhaust outlet, keep blower fan group exhaust outlet pressure, reduced the blower fan group exhaust outlet pressure loss.
