Abstract
The utility model discloses an air channel structure of a kitchen range hood, which comprises a cylindrical shell, wherein an air outlet is arranged on the side wall of the shell, and an air inlet is arranged on one bottom wall of the shell in the axial direction, so that the flowing direction of air flow is vertical to the flowing direction of air flow; the shell is internally provided with a rotating shaft, a cross flow fan is installed on the rotating shaft, and an axial flow fan is installed on the rotating shaft and positioned on one side, close to the air inlet, of the cross flow fan. Adopt above-mentioned technical scheme, the utility model discloses a kitchen lampblack absorber wind channel structure installs in the turning of pipeline, the position of buckling to inside is provided with axial fan and cross-flow fan, and it is rotatory to drive through the motor, thereby plays better promotion velocity of flow effect when the air current commutates in the pipeline, improves the efficiency of taking a breath of lampblack absorber.
Description
Technical Field
The utility model relates to a kitchen lampblack absorber wind channel structure belongs to smoke ventilator technical field.
Background
The fume exhauster is also called as fume exhauster, and is a kitchen electrical appliance for purifying kitchen environment. The kitchen ventilator is arranged above a kitchen stove, can rapidly pump away waste burnt by the stove and oil fume harmful to human bodies generated in the cooking process, and exhaust the waste and the oil fume to the outside, reduces pollution, purifies air, and has the safety guarantee effects of gas defense and explosion prevention. The range hood discharges air out of the room through the air pipes, and the structure with the air ducts reasonably arranged helps to exhaust air smoothly, so that the operation efficiency of the range hood is improved. Most of household air pipes cannot be directly led to the outside but have corners and bent parts, and wind resistance is easily caused at the corner parts, so that the speed of air flow is reduced after the air flow directly impacts the bent parts, and the exhaust efficiency is greatly reduced.
SUMMERY OF THE UTILITY MODEL
Therefore, the to-be-solved technical problem of the utility model is to provide a higher kitchen lampblack absorber wind channel structure of exhaust efficiency.
In order to achieve the above purpose, the utility model discloses a kitchen range hood air channel structure, which comprises a cylindrical shell, wherein an air outlet is arranged on the side wall of the shell, and an air inlet is arranged on one axial bottom wall of the shell, so that the air flow flowing direction is vertical to the air flow flowing direction; the shell is internally provided with a rotating shaft, a cross flow fan is installed on the rotating shaft, and an axial flow fan is installed on the rotating shaft and positioned on one side, close to the air inlet, of the cross flow fan.
The rotating shaft is far away from one end of the air inlet and penetrates out of the outer side of the shell to be connected with a driving motor.
The casing includes two side plate portions and lateral wall portion, be provided with the eaves of inside side bending on the side plate portion, lateral wall portion is a bent plate, the both sides of bent plate weld in on the eaves.
The air inlet is circular, a support is arranged at the position of the air inlet, and one end of the rotating shaft is installed on the support.
The air flow outflow direction of the air outlet is tangent to the circle of the air inlet.
Adopt above-mentioned technical scheme, the utility model discloses a kitchen lampblack absorber wind channel structure installs in the turning of pipeline, the position of buckling to inside is provided with axial fan and cross-flow fan, and it is rotatory to drive through the motor, thereby plays better promotion velocity of flow effect when the air current commutates in the pipeline, improves the efficiency of taking a breath of lampblack absorber.

As shown in the figures, the utility model provides an air channel structure of a kitchen range hood, which comprises a cylindrical shell 1, wherein an air outlet 2 is arranged on the side wall of the shell 1, and an air inlet 3 is arranged on one axial bottom wall of the shell 1, so that the inflow direction of air flow is vertical to the outflow direction of air flow; a rotating shaft 4 is arranged in the shell 1, a cross flow fan 5 is installed on the rotating shaft 4, and a shaft flow fan 6 is installed on the rotating shaft 4 and on one side, close to the air inlet 3, of the cross flow fan 5.
And one end of the rotating shaft 4, which is far away from the air inlet 3, penetrates out of the shell 1 and is used for connecting a driving motor.
The housing 1 includes two side plate portions 11 and a side wall portion 12, an inward-bending eave 13 is provided on the side plate portion 11, the side wall portion 12 is a bent plate, and both sides of the bent plate are welded on the eave 13.
The air inlet 3 is circular, a support 7 is arranged at the position of the air inlet 3, and one end of the rotating shaft 4 is installed on the support 7.
The air flow outflow direction of the air outlet 2 is tangent to the circular shape of the air inlet 3.
Adopt above-mentioned technical scheme, the utility model discloses a kitchen lampblack absorber wind channel structure installs in the turning of pipeline, the position of buckling to inside is provided with axial fan 6 and cross-flow fan 5, and it is rotatory to drive through the motor, thereby plays better promotion velocity of flow effect when the air current commutates in the pipeline, improves the efficiency of taking a breath of lampblack absorber.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
