Content of the invention
The smoke exhaust ventilator of the present invention includes：Be formed as the bowl-shape upper cover of back-off；With cover upper cover lower section there is opening
The lower cover in face.In addition, smoke exhaust ventilator is formed with suction inlet in the central portion of lower cover, the space between upper cover and lower cover is provided with
The fan of exhaust and motor.And, opening surface be divided near user with front side with front openings faces and away from
Inboard opening surface two parts of the inboard of user.When making respectively by outer from the periphery with front openings face and inboard opening surface
When the region that week surrounds in the line segment that vertical extends and lower cover is with front side trap portion and inboard trap portion, catch with front side
The volume in collection portion is more than the volume of inboard trap portion.
From suction inlet suck oil smoke because with front side trap portion volume be more than inboard trap portion volume, will not
From overflowing with front side trap portion, it is not result in that the arresting efficiency of oil smoke declines.
Brief description
Fig. 1 is the side view of the smoke exhaust ventilator of embodiments of the present invention.
Fig. 2 is the sectional view of the smoke exhaust ventilator of prior art.
Specific embodiment
Hereinafter, referring to the drawings embodiments of the present invention are illustrated.
（Embodiment）
Fig. 1 is the side view of the smoke exhaust ventilator of embodiments of the present invention.As shown in figure 1, embodiments of the present invention
Smoke exhaust ventilator includes upper cover 1 and lower cover 2.The substantially central portion of lower cover 2 is provided with suction inlet 3, waste gas etc. is inhaled from suction inlet 3
Enter.Detachably it is provided with the filter 4 of the oil of trapping oil smoke in front of suction inlet 3.Herein, as one, filter 4 is used
Screw loads and unloads.
The back-off that upper cover 1 is formed as slim is bowl-shape.The waste gas of generation, oil smoke, the water such as when cooking in kitchen for receiving
The lower cover 2 of steam, foul smell etc. covers the lower section of upper cover 1, and has opening surface 2a.In addition, by the region that lower cover 2 is surrounded be for
The trap portion 11 of the oil smoke of exhaust.
In addition, opening surface 2a is divided near user 12 with front side 13 with front openings face 2b with away from user
Inboard opening surface 2c two parts of 12 inboard 14.When making respectively by from the periphery with front openings face 2b and inboard opening surface 2c
The line segment that extends in vertical 15 of periphery and the region that surrounds of lower cover 2 be with front side trap portion 11a, inboard trap portion 11b
When, the volume with front side trap portion 11a is more than the volume of inboard trap portion 11b.
Alternatively, it is also possible to using for example injured prevent with the protecting wire net of metal mesh shaped substitute filter 4.
In addition, the space 10 between upper cover 1 and lower cover 2, it is provided with fan 5 and the motor 6 of exhaust.In upper cover 1
The back side, be provided with the joint 7 for discharging the waste gas etc. sucking from suction inlet 3.Fan 5 is, for example, turbofan.In addition, shape
Become to have the exhaust pathway for connecting suction inlet 3 and joint 7., compared with Sirocco fan, price is low and fan is imitated for turbofan
Rate is high.
In addition, lower cover 2 and suction inlet 3 are in front side 13 whereabouts inclined upward with from the back side 14 with respect to user 12
Shape.In other words, lower cover 2 is to be convex to the cone shape of upper cover 1.And, along formed cone shape from the back side 14 to
Inclined plane 2d that front side 13 is gone, is configured with filter 4, fan 5 and motor 6.
In addition, as angle of inclination, as long as with can in the height between the top surface of the bottom surface of lower cover 2 and upper cover 1
The angle of the inclination of storage fan 5 and motor 6, can adopt arbitrarily angled.
In addition, fan 5 using turbofan but it is also possible to using Sirocco fan with shell etc..In addition, joint 7 is pacified
It is loaded on the opening portion 8 at the back side of upper cover 1.By making the angle of inclination of fan 5 consistent with the opening angle of the shield 9 of joint 7,
Be capable of the minimizing of the resistance of exhaust pathway, air quantity guarantee and noise reduces.However, joint 7 can be to be not only to set
It is placed in the back side of upper cover 1 it is also possible to be arranged at the opening of side or upper surface etc..
In this smoke exhaust ventilator, oil smoke from the front of user 12 along with respect to user 12 with from the back side 14 to
With the lower cover 2 of front side 13 whereabouts inclined upward, it is sucked into suction inlet 3.Therefore, the trap portion 11 of the rake of lower cover 2 deepens, that is,
Make to be the shallower structures of trap portion 11 such as shallow cover type smoke exhaust ventilator, also can prevent the arresting efficiency of oil smoke from declining.
In addition, fan 5 and motor 6 with respect to user 12 with from the back side 14 towards with front side 13 whereabouts inclined upward.
And, the oil smoke from the front of user 12 is sucked into and goes upwards to front side 13 with from the back side 14 with respect to user 12
The fan 5 that side tilts, so the suction plane of fan 5 is towards oblique front lower place, the position movement of suction inlet 3 is to front.Therefore, even if
It is the shallower structures of trap portion 11 such as shallow cover type smoke exhaust ventilator, also can prevent the arresting efficiency of oil smoke from declining further.
In addition, as shown in figure 1, inclined plane 2d extreme lower position 2e, be provided with oily trap portion 16.It is attached to lower cover 2 He
The oil of upper cover 1 is flowed into oily trap portion 16, so the organic efficiency of oil is improved, smoke exhaust ventilator periphery will not be further because of oil
Dirty.
Utilization possibility in industry
In the present invention, even the shallower structure of trap portion such as shallow cover type smoke exhaust ventilator, also it is required for the portions such as cowling panel
Part, useful as smoke exhaust ventilator realizing arresting efficiency raising etc..
