Problems solved by technology

[0002] Most of the wind wheels used in the existing range hoods are centrifugal. The structure of the centrifugal wind wheel is complex and difficult to disassemble. When the main exhaust components of the wind turbine are used, a large amount of oil fume is introduced into the interior of the wind rotor during the smoking process, causing oil dirt to adhere to the blades of the wind rotor and other components, affecting normal use and reducing the working efficiency of the wind rotor

Embodiment 1

[0042] Such as Figure 1-4 As shown, a range hood with an axial-flow wind wheel is provided with a hood main body 1, and an axial-flow exhaust assembly 2 is installed inside the hood main body 1, and the plane L where the air inlet 21 of the exhaust assembly 2 is located is parallel to The plane P where the air outlet 22 is located.

[0043] The air inlet 21 and the air outlet 22 of the axial flow exhaust assembly 2 are parallel to each other, and the interior of the exhaust assembly 2 is a through cavity of a straight passage.

[0044] The internal assembly of the exhaust assembly 2 is as follows:

[0045] The exhaust assembly 2 includes a volute 23 , and the upper and lower surfaces of the volute 23 are correspondingly provided with outlet and air inlets 21 .

[0046] In order to improve the overall ventilation effect of the ventilation assembly 2 , the volute 23 is provided with an air outlet 22 and a plurality of air inlets 21 .

[0047] The multi-inlet 21 is used to in...

Embodiment 2

[0062] A range hood with an axial-flow wind wheel, other features are the same as in Embodiment 1, the difference is: as figure 1 As shown, in order to prevent the inside of the ventilation assembly 2 from being polluted, this embodiment does not pass the gas with soot into the inside of the ventilation assembly 2, effectively keeping the inside of the ventilation assembly 2 clean.

[0063] The air inlet 21 communicates with the air inlet group 4 of the hood main body 1 through the air duct 3 , and the air outlet 22 communicates with the exhaust duct 5 at the top of the hood main body 1 .

[0064] The air inlet group 4 is divided into a clean air inlet group and an oil fume air inlet group, and the clean air inlet group and the oil fume air inlet group are connected through an independent air duct 3 .

[0065] The upper air inlet channel 31 communicates with the clean air inlet group 41 and the air inlet 21 of the exhaust assembly 2 .

[0066] The lower air inlet duct 32 comm...

Embodiment 3

[0071] A range hood with an axial-flow wind wheel, other features are the same as in Embodiment 1, the difference is: as figure 1 As shown, in this embodiment, according to the principle of aerodynamics, the outer surface of the housing 11 of the main body of the hood 1 serves as a guiding surface for the moving direction of the oil fume, rather than forming a cover area for gathering the oil fume.

[0072] All outer surfaces of the casing 11 can be used as guiding surfaces, and the casing 11 does not include any platform structure such as a plane, an inclined plane or a non-planar surface, which is arranged above the cooktop.

[0073] There is at least one air inlet group 4 located in the non-covering area of ​​the casing 11 .

[0074] According to the principle of aerodynamics, after the oil fume is generated, the oil fume will move along the outer surface of the housing 11 and be sucked into the air duct 3 inside the hood main body 1 by at least one air inlet group 4 provid...

Abstract

The invention discloses a range hood with an axial-flow type wind wheel. The range hood comprises a range hood main body, wherein an axial-flow type exhaust component is assembled inside the range hood main body; a plane L on which the gas inlet of the exhaust component is arranged is parallel to a plane P on which the a gas outlet is arranged; the exhaust component comprises a volute; the gas outlet and the gas inlet are correspondingly formed in the upper surface and the lower surface of the volute; a motor is assembled inside the volute; blades are rotationally assembled at the rotor end ofthe motor; the plane M of the central points of the blades is parallel to the plane L and the plane P respectively; the gas inlet is communicated with air inlet groups of the range hood main body through an air flue; the gas outlet is communicated with a smoke discharge channel in the top of the range hood main body; a plurality of air inlet groups are arranged; the air inlet groups comprise cleaned air inlet groups and cooking fume air inlet groups. The range hood with the axial-flow type wind wheel is simple in structure and convenient to mount and dismount; meanwhile, according to air dynamic principle, cooking fume is not introduced into the axial-flow type wind wheel but is discharged directly, then the interior of the wind wheel is kept clean, and the service life of the wind wheelis prolonged.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood with an axial-flow wind wheel. Background technique [0002] Most of the wind wheels used in the existing range hoods are of centrifugal type, and the structure of the centrifugal wind wheel is complicated, and it is difficult to disassemble and assemble. A large amount of oil fume is introduced, causing oil dirt to adhere to the wind rotor blades and other components, affecting normal use and reducing the working efficiency of the wind rotor. [0003] Therefore, aiming at the deficiencies of the prior art, it is very necessary to provide a range hood with an axial-flow wind wheel to solve the deficiencies of the prior art. Contents of the invention [0004] The object of the present invention is to avoid the deficiencies of the prior art and provide a range hood with an axial-flow wind wheel. The range hood with an axial-flow wind wheel has a simple structure...
