Example Embodiment

[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] The double volute wind turbine fan of the present invention, such as figure 1 , 2 As shown, it includes a first fan 01 and a second fan 02;

[0043] The first fan 01 includes a first volute 11, a first wind wheel 12, and a first motor 13. The first wind wheel 12 and the first motor 13 are assembled in the first volute 11 and the first motor 13 drives the first wind wheel 12. The first volute 11 has a first air inlet 14 and a first air outlet 15;

[0044] The second fan 02 includes a second volute 21, a second fan wheel 22, and a second motor 23. The second fan wheel 22 and the second motor 23 are assembled in the second scroll casing 21 and the second motor 23 drives the second fan wheel 22. The second volute 21 has a second air inlet 24 and a second air outlet 25;

[0045] The first volute 11 and the second volute 21 are connected together, and the first air ...

Abstract

The invention discloses a double volute wind wheel fan and belongs to air exhaust devices. An existing single volute wind wheel fan has the defects of disaccording with an extractor hood in air suction, unstable in operation, and relatively low in operation efficiency. The double volute wind wheel fan comprises a first fan and a second fan. A first volute of the first fan is connected with a second volute of the second fan. A first air outlet of the first fan and a second air outlet of the second fan are converged together and are jointly connected with an air outlet port. When used for different rangers, the double volute wind wheel fan is even in air suction and enables a whole machine to be enlarged in air quantity, improves smoke suction effect, and remarkably reduces noise. Matching and electronic control of double motors are more suitable for independent or linkage operation of a single range or double ranges, improve efficiency of the whole machine and remarkably show the advantage of energy conservation. Different shapes of air outlets and corresponding ports are selected according to shell bodies of different extractor hoods so as to reduce air outlet resistance and vortex, and therefore air quantity is increased and noise is reduced.

Description

technical field [0001] The invention belongs to an exhaust device, in particular to a double-volute wind turbine fan used for range hoods. Background technique [0002] Existing fans for range hoods are applied to the main Chinese range hoods currently on the market, and are usually assembled by a single wind wheel volute and a motor. In general, there are two stoves under the range hood. When the stove is used at the same time, the motor on one side of the volute casing fan hinders the air intake, which will cause uneven air suction on both sides, resulting in poor oil absorption effect, and poor stability during operation. Also there is above defect because single motor work can't control air intake. [0003] From the design point of view, the existing range hood fan has the following defects: ①The volute, wind wheel and motor of the fan are all configured in a single configuration, and uneven air suction will inevitably occur on the air intake channel, resulting in limit...
