Abstract
The invention discloses a structural improvement on a centrifugal fan group of a range hood. The range hood comprises an air channel group and the centrifugal fan group, wherein the centrifugal fan group is fixedly arranged in the air channel group and comprises a volute and a fan; and by taking a using direction as reference, the side wall of the lower end of the air channel group is provided with a first chamfering structure which inclines to the inner side of the first chamfering structure, and a second chamfering structure in the same direction as the first chamfering structure is arranged on the volute of the centrifugal fan group close to the first chamfering structure on the air channel group. The distance between the centrifugal fan group and the air channel group at the first chamfering structure is effectively increased, so that air enters the range hood smoothly, and the supply air rate of the range hood is improved.
Description
Technical field
The present invention relates to a kind of range hood, particularly a kind of range hood centrifugal fan group structural improvement.
Background technology
At present, the air channel group of range hood is owing to the restriction of complete machine structure, and its sidewall is provided with a chamfering that tilts to the inside, so just causes the spiral case of centrifugal fan group to reduce in the air intake distance of this side, and range hood has some setbacks at the air intake of this side.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of range hood centrifugal fan group structural improvement, use the range hood centrifugal fan group of this improvement after the range hood air intake smooth and easy, improved its intake.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of range hood centrifugal fan group structural improvement, range hood comprises air channel group and centrifugal fan group, the centrifugal fan group is fixedly arranged in the group of air channel, the centrifugal fan group comprises spiral case and blower fan, to use direction to be benchmark, group lower end, air channel sidewall is provided with first chamfering structure to its inboard inclination, the spiral case of centrifugal fan group is provided with second chamfering structure identical with the first chamfering structure direction near the first chamfering structure position on the group of air channel, so just increased air channel group and centrifugal fan group distance, made air intake more smooth and easy at its first chamfering structure place.
As a further improvement on the present invention, second chamfering structure on the spiral case of described centrifugal fan group is parallel with first chamfering structure on the group of air channel, has guaranteed that like this blower fan group and air channel interblock space are even, and it is smooth and easy to help the range hood air intake.
As a further improvement on the present invention, on the spiral case of described centrifugal fan group second chamfering structure for facing chamfering directly.
As a further improvement on the present invention, the angle of the spiral case lateral wall of this second chamfering structure and centrifugal fan group formation is 10 °-80 °.
As a further improvement on the present invention, second chamfering structure is the cambered surface chamfering on the spiral case of described centrifugal fan group.
As a further improvement on the present invention, the arc radius of the cambered surface of this second chamfering structure is 5-100mm.
As a further improvement on the present invention, the width of second chamfering structure is 10-100mm on the spiral case of centrifugal fan group.
Useful technique effect of the present invention is: the present invention is by being provided with second chamfering structure identical with its incline direction in the group sidewall first chamfering structure position, the corresponding air channel of the spiral case of centrifugal fan group, effectively increased centrifugal fan group and air channel group distance in the first chamfering position, make that the range hood air intake is smooth and easy, improved its intake.

The specific embodiment
Embodiment: a kind of range hood centrifugal fan group structural improvement, range hood comprises air channel group 1 and centrifugal fan group 2, centrifugal fan group 2 is fixedly arranged in the air channel group 1, centrifugal fan group 2 comprises spiral case 22 and blower fan 21, to use direction to be benchmark, group 1 lower end sidewall in air channel is provided with first chamfering structure 4 to its inboard inclination, the spiral case 22 of centrifugal fan group 2 is provided with second chamfering structure 3 identical with first chamfering structure, 4 directions near first chamfering structure, 4 positions on the group 1 of air channel, it is even at its first group of 1 interbody spacer with centrifugal fan group 2 so just to have increased air channel group 1, and it is smooth and easy to help the range hood air intake.
Described this second chamfering structure 3 is 10 °-80 ° with the angle of the spiral case 22 lateral walls formation of centrifugal fan group 2.
The arc radius of the cambered surface of described this second chamfering structure 3 is 5-100mm.
The width of second chamfering structure 3 is 10-100mm on the spiral case 22 of described centrifugal fan group 2.
