Embodiment
As shown in Figures 1 and 2, high-performance axial flow blower used for range hood, including shell and in shell by electricity
The centrifugal wind wheel 2 that machine 1 drives, the centrifugal wind wheel 2 are at least made up of radially-arranged arc shaped blade 3, adjacent arc shaped blade 3
Between form air channel 4, exhaust outlet of the air channel 4 along direction from inside to outside to blower fan tilts.Inclined air channel 4, which is designed, to be caused
High-pressure blast caused by centrifugal wind wheel 2 collision shell inwall after to blower fan exhaust outlet rebound, without be again introduced into from
Heart blower fan, the air channel 4 for being designed to greatly to reduce centrifugal wind wheel 2 export the flow-disturbing between outer casing inner wall, improve wind
The overall motive effect of fluid of machine, so as to reduce the motion windage of centrifugal blower so that centrifugal blower can high-speed rotation simultaneously
Produce more than 600Pa high-pressure blast so that the grease in oil smoke can congeal into small oil droplet, improve the separating degree of grease.
In order to further carry out further water conservancy diversion to the flow direction of the wind of blower fan, the top of the centrifugal wind wheel 2, which is additionally provided with, leads
Solar or lunar halo 5, air-ducting ring 5 is overall be in back-off cover body, cover body outer wall is radially distributed a guide vane 6, shape between adjacent guide vane 6
Air-guiding aisle radially, guide vane 6 can obstruct wind and circular flow-disturbing produced in housing, make it can only leading along radial direction
Wind passage flows to the exhaust outlet of housing, the high-pressure blast of radial rotary caused by centrifugal wind wheel 2 is become axial stream from what is smoothed out
It is dynamic, energy expenditure is reduced, is further ensured that the motive effect of fluid of whole blower fan.
In order to prevent the grease for condensing upon inner walls from being moved upwards under the drive of wind, the inwall of the shell is in air channel
The relevant position in 4 exits is provided with solidifying oil ring 7, coagulates the surface that oil ring 7 protrudes outer casing inner wall, is prevented by solidifying oil ring 7 liquefied
Grease moves upwards, and it flows downward along outer casing inner wall under gravity.Air channel 4 entrance of the lower house in centrifugal wind wheel 2
Locate inside bending and form food tray 18, in order to receive the grease that housing wall flows down.
For the ease of the dismounting of blower fan, to be cleaned or be repaired, a variety of structures being readily disassembled are employed.Shell first
Fastened and formed by the upper-lower casing 8,9 separated, installation and removal can be by rotating against upper-lower casing 8,9 so that buckle overlaps
