Description
Technical Field
The utility model belongs to the technical field of centrifugal fan structure technique and specifically relates to indicate a spiral case and have centrifugal fan of this spiral case.
Background
At present, an integrated kitchen range and a range hood become one of necessary kitchen equipment. The centrifugal fan is widely applied to the field of range hoods due to the advantages of large suction force, low noise, compact structure and the like. Centrifugal fans typically include a volute, an impeller, and a motor. However, the volute of the existing centrifugal fan is of a spiral structure or an arc structure, and the spiral structure or the arc structure causes continuous air flowing in the volute, so that the noise is high.
Disclosure of Invention
The utility model discloses problem to prior art provides a spiral case and have centrifugal fan of this spiral case, novel structure, design benefit, stable in structure, the setting up of flat panel section makes this internal wind of process spiral case interrupted, broken up by the flat panel section, reduces the continuous flow that the wind flowed, overcomes that traditional spiral case all is arc or spiral to walk wind, the wind flows and causes the great problem of noise in succession.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a pair of spiral case, including the spiral case body, the spiral case body is provided with total air outlet, the spiral case body is provided with the flat panel section.
And the periphery of the main air outlet is provided with a mounting panel, and the mounting panel is fixedly connected with the volute body.
Wherein, the installation panel and the volute body are integrally formed.
Wherein, be provided with a plurality of first mounting holes on the mounting panel.
The volute comprises a volute body and is characterized in that mounting pieces are fixedly arranged at two ends of the volute body, and a plurality of second mounting holes are formed in the mounting pieces.
The utility model also provides a centrifugal fan, including the fan body and the spiral case, the middle part at the spiral case body is installed to the fan body.
Wherein, the periphery of fan body still overlaps and is equipped with the insulating plastic body.
The utility model has the advantages that:
the utility model discloses novel structure, design benefit, stable in structure, the setting of flat panel section makes this internal wind of process spiral case interrupted, broken up by the flat panel section, reduces the continuous flow that the wind flowed, overcomes that traditional spiral case all is that arc or spiral walk wind, wind flow and cause the great problem of noise in succession.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
A volute is shown in figure 1 and comprises a volute body 1, wherein the volute body 1 is provided with a main air outlet 2, and the volute body 1 is provided with a flat panel section 3. Specifically, the setting of flat panel section 3 makes the wind through in the spiral case body 1 be broken up, broken up by flat panel section 3, reduces the continuous flow of wind current, overcomes traditional spiral case and all is the arc or spiral and walks wind, the wind current causes the great problem of noise in succession, this embodiment novel structure, design benefit, stable in structure.
In the volute of this embodiment, the periphery of the main air outlet 2 is provided with the installation panel 4, and the installation panel 4 is fixedly connected with the volute body 1. Particularly, the volute is convenient to install in a range hood or an integrated stove, and installation is convenient; the installation panel 4 and the volute body 1 are integrally formed, and the installation panel 4 and the volute are more stable in connection structure due to the arrangement.
In the volute of this embodiment, the mounting panel 4 is provided with a plurality of first mounting holes 5. Specifically, the installation panel 4 is conveniently fixed on the integrated kitchen range or the range hood by the aid of the first installation holes 5 and external screws and bolts.
The volute of this embodiment, the both ends of volute body 1 are all fixed and are provided with installation piece 6, be provided with a plurality of second mounting holes 7 on the installation piece 6. Specifically, the installation piece 6 with the cooperation of second mounting hole 7 is fixed, and above-mentioned setting is convenient to be fixed installation piece 6 and spiral case body 1 on integrated kitchen or smoke ventilator with external screw, bolt cooperation convenience.
The utility model also provides a centrifugal fan, including fan body 8 and the spiral case, fan body 8 is installed at the middle part of spiral case body 1. Specifically, the setting of the flat plate section 3 of the volute body 1 enables wind passing through the volute body 1 to be broken and scattered by the flat plate section 3, so that continuous flow of wind flow is reduced, and the problem that the traditional centrifugal fan is arc-shaped or spiral wind, and the wind flow continuously causes large noise is solved.
This embodiment a centrifugal fan, fan body 8's periphery is still overlapped and is equipped with insulating plastic body 9. Specifically, the above arrangement effectively improves the safety, prevents the electric leakage when the operator touches the fan body 8, improves the installation and is reliable, and in addition, the insulating colloid can also protect the fan body 8, and the structure is reliable.
The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, but all the technical solutions of the present invention are within the scope of the present invention.
