at present, the volute installation mode mainly comprises the installation of the outlet of the volute and the top air outlet plate and the connection and installation of the rear volute bracket and the case, the existing installation mode easily generates resonance phenomenon, abnormal sound can be caused, and particularly the resonance of the rear volute bracket and the case is serious.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the first technical problem that will solve is not enough to above-mentioned prior art, provides one kind and can make the spiral case rear portion not contact with quick-witted case to solved the resonance phenomenon that causes because of spiral case support and the contact of quick-witted case at spiral case rear portion.
The second technical problem to be solved in the present invention is to provide a range hood with the spiral case.
The utility model provides a technical scheme that above-mentioned first technical problem adopted does: a volute, comprising a volute body, characterized in that: the volute body is provided with a mounting bracket capable of mounting the volute body in a hanging manner.
In order to mount the volute body in a suspension manner and reduce the resonance between the volute and the chassis, the volute body comprises a circumferential wall, and the mounting bracket can be arranged on the circumferential wall and extend above the circumferential wall.
In order to mount the volute body in a hanging mode, the mounting support comprises a first side plate and a second side plate which are longitudinally arranged on the annular wall at intervals, and the mounting support further comprises a first top plate which is connected with the tops of the first side plate and the second side plate.
The utility model provides a technical scheme that above-mentioned second technical problem adopted does: the utility model provides an use range hood that has above-mentioned spiral case, includes the fan frame, the fan frame includes the second roof, the spiral case body still includes the air outlet, its characterized in that: the volute body is connected and fixed with the top plate only at two positions, namely the air outlet and the first top plate of the mounting bracket, so that the volute body is suspended in the fan frame.
In order to facilitate the connection between the air outlet and the air frame, a connecting part extending towards the outer side is formed at the opening part of the air outlet, and the connecting part is fixedly connected with the second top plate.
Compared with the prior art, the utility model has the advantages of: the mounting support fixedly connected with the top plate of the case is arranged on the annular wall of the volute body, so that the volute body is only fixedly connected with the top plate at two positions of the air outlet and the mounting support, the volute body is mounted in a hanging mode, the front side, the rear side, the left side, the right side and the bottom of the volute body are not in contact with the case, and the resonance phenomenon of the volute body and the case is reduced.

fig. 2 is a schematic view of a volute of a range hood according to an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
Referring to fig. 1 and 2, a range hood, a ceiling type range hood, includes a fan frame 2 and a fan disposed in the fan frame 2, the fan includes a volute 1.
The volute 1 comprises a volute body 12, the volute body 12 comprising a front cover plate 121, a rear cover plate 122 and an annular wall 123 disposed between the front cover plate 121 and the rear cover plate 122. The volute 1 further includes a mounting bracket 11 provided on the annular wall 123 extending above the annular wall 123 for suspension mounting of the volute body 12. The mounting bracket 11 includes a first side plate 111 and a second side plate 112 spaced apart longitudinally on the annular wall 123, and the mounting bracket 11 further includes a first top plate 113 connecting tops of the first side plate 111 and the second side plate 112, the first top plate 113 extending in a transverse direction.
A second top plate 21 is arranged on the upper portion of the fan frame 2, the volute body 12 further includes an air outlet 13, a connecting portion 14 extending to the outside is formed at an opening portion of the air outlet 13, and the connecting portion 14 is fixedly connected with the second top plate 21. The first top plate 113 is closely attached to and fixed to the second top plate 21.
The volute 1 is only fixedly connected with the second top plate 21 of the fan frame 2 at two positions, namely the air outlet 13 and the first top plate 113 of the mounting bracket 11, so that the volute 1 is suspended in the fan frame 2, and the front side, the rear side, the left side and the right side of the volute 1 are not in contact with the inner side of the fan frame 2, thereby reducing resonance between the volute 1 and the fan frame 2 and effectively reducing vibration noise during the operation of the range hood.
Referring to fig. 1, in addition to the falling problem of the range hood, the foam 3 is added around the volute during factory assembly, and the foam 3 is extracted when the user installs the range hood at home, so that the damage of the volute caused by falling is prevented.
