A kind of top-sucking kitchen ventilator, including casing, wind cabinet, exhaust fume collecting hood, oil network and lubricating cup, wind cabinet are mounted in casing,
Impeller is installed, exhaust fume collecting hood is mounted on the bottom of casing, and oil network is mounted on the air inlet of exhaust fume collecting hood, and lubricating cup is mounted in inside wind cabinet
The bottom of oil network, the wind cabinet are tiltedly mounted in casing, the axial line and bottom of shell horizontal plane of the installation of wind cabinet internal impeller
Angle it is at an acute angle so that impeller air inlet inclination downward.
Preferably, the axial line of the wind cabinet internal impeller installation and the angle of bottom of shell horizontal plane are 10 ° -80 °.
Preferably, the top-sucking kitchen ventilator further includes deflector, and the deflector is obliquely installed in range hood
Below wind cabinet, the top of exhaust fume collecting hood, deflector includes water conservancy diversion plane, and the upper end of the water conservancy diversion plane, which is equipped with to blower direction, to be extended
Curved surface is drained out, and the lower end of water conservancy diversion plane is extended to casing direction connects oil plane, connects the junction of oil plane Yu water conservancy diversion plane
It is provided with oil leaking hole, is provided with installation position at left and right sides of water conservancy diversion plane.
Preferably, the deflector and exhaust fume collecting hood are in 10 ° of -80 ° of angles.Specific angle is matched with range hood wind cabinet to be set
It is fixed, for drainage and Oil Guide.
Preferably, the number of the oil leaking hole is one or more.Deflector catches the greasy dirt that air duct flows down, due to leading
Flowing plate is inclined, and greasy dirt can be flowed out by oil leaking hole since gravity is toward flowing down, enter lubricating cup by oil network.
Preferably, installation position is the mounting plane by extending at left and right sides of water conservancy diversion plane, is set on the mounting plane
There is mounting hole, installation position is connected and fixed by screw or riveting method with range hood casing.
Preferably, for deflector in addition to the installation position of side, exposed face is big plane.To reduce the contact surface of fluid and deflector
Product reduces energy loss and liquid collision.
Preferably, the cabinet top offers upper opening, and enclosure top is equipped with air outlet, and the air outlet passes through air draft
Pipeline is connected to outdoor or common flue, and exhaust duct passes through the upper opening of cabinet top.
Compared with prior art, the beneficial effect of technical solution of the present invention is: the present invention provides a kind of top suction type fume-exhausting
Machine, the wind cabinet are tiltedly mounted in casing, wind cabinet internal impeller installation axial line and bottom of shell horizontal plane angle at
Acute angle, so that the inclination of impeller air inlet is downward.Compared to the extractor hood structure in more general conventional vertical air duct, structure of the invention is not
It will increase too many components, in terms of the manufacturing and material cost and no less than traditional extractor hood structure.But the present invention inhales
The structure of kitchen ventilator can be obviously improved the oil suction smoke exhaust efficiency of range hood, while also can be reduced and entering the wind crossfire inside smoke machine
Effect, to reduce noise.

Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
In order to better illustrate this embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent actual product
Size；
To those skilled in the art, it is to be understood that certain known features and its explanation, which may be omitted, in attached drawing
's.
The following further describes the technical solution of the present invention with reference to the accompanying drawings and examples.
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of top-sucking kitchen ventilator, including casing 6, wind cabinet 4, exhaust fume collecting hood 5, oil network
2 and lubricating cup 1, wind cabinet 4 be mounted in casing 6, impeller is installed, exhaust fume collecting hood 5 is mounted on the bottom of casing 6, oil network inside wind cabinet 4
2 are mounted on the air inlet of exhaust fume collecting hood 5, and lubricating cup 1 is mounted in the bottom of oil network 2, and the wind cabinet 4 is tiltedly mounted in casing 6, wind cabinet
The axial line of 4 internal impellers installation and the angle of 6 bottom water plane of casing are at 10 ° of -80 ° of acute angles, so that impeller air inlet tilts
Downward.
As shown in Fig. 2, the top-sucking kitchen ventilator further includes deflector 3, the deflector 3 is obliquely installed in fume-exhausting
The lower section of wind cabinet 4 of machine, exhaust fume collecting hood 5 top, deflector 3 includes water conservancy diversion plane 31, the upper end of the water conservancy diversion plane 31 be equipped with to
Drainage curved surface 32 is extended in blower direction, and the lower end of water conservancy diversion plane 31 is extended to 6 direction of casing connects oil plane 33, connects oil plane
33 are provided with oil leaking hole 34 with the junction of water conservancy diversion plane 31, and the left and right sides of water conservancy diversion plane 31 is provided with installation position 35.It uses
In the process, 31 pairs of 3 water conservancy diversion plane of the deflector air-flows entered inside casing 6 drain, and drain curved surface 32 by deflector 3
Air-flow is led into inside wind cabinet 4；Meanwhile the greasy dirt to drip from 4 bottom plate of wind cabinet leaves along 3 water conservancy diversion of deflector, from oil leaking hole
34 discharges, and enter lubricating cup 1 by oil network 2.
The deflector 3 is in 10 ° of -80 ° of angles with exhaust fume collecting hood 5.Specific angle and 4 match settings of range hood wind cabinet, are used
In drainage and Oil Guide.
The number of the oil leaking hole 34 is one or more.Deflector 3 catches the greasy dirt that air duct flows down, due to deflector
3 is inclined, and greasy dirt can be flowed out by oil leaking hole 34 since gravity is toward flowing down, enter lubricating cup 1 by oil network 2.
Installation position 35 is the mounting plane extended by the left and right sides of water conservancy diversion plane 31, and the mounting plane is equipped with peace
Hole is filled, installation position 35 is connected and fixed by screw or riveting method with range hood casing 6.
For deflector 3 in addition to side installation position 35, exposed face is big plane.To reduce the contact area of fluid Yu deflector 3,
Reduce energy loss and liquid collision.
Upper opening is offered at the top of the casing 6, enclosure top is equipped with air outlet, and the air outlet is connected by exhaust duct
It is connected to outdoor or common flue, exhaust duct passes through the upper opening at 6 top of casing.
The range hood of this implementation and the principle Analysis of traditional range hood are as follows:
As shown in figure 3, the air inlet runner of traditional range hood vertical air plenums is assumed to be a, b, c, d totally 4 runners, runner without
Method accomplishes unified flow direction, and can very likely be stopped by the plane of air duct bottom, to turn back or runner is excessively curved
Song causes noise increase and wind loss.
As shown in figure 4, oil smoke passes through oil network 2 by 1 surrounding of lubricating cup and enters smoke machine casing after range hood starting of the present invention
Inside 6, deflector 3 can be oriented to runner, so that oil smoke is flowed towards same direction always, into air duct, complete cigarette
Machine oil suction smoke exhaust process.Assuming that the air inlet runner of smoke machine is still a, b, c, d totally 4 runners, but compared to traditional fume-exhausting
For machine vertical air plenums, runner is effectively integrated and is drained, and is bent less, effectively oil smoke can be made to enter inside air duct,
Complete oil suction smoke exhaust process.
