Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings.
If Fig. 1 is structure of the invention oblique view.Fig. 2 is structure of the invention front view.Fig. 3 is structure of the invention rearview.
Fig. 4 is the left view of Fig. 3.Fig. 5 is the A-A views of Fig. 2.Fig. 6 is the local B views of Fig. 5.Fig. 7 is that air duct coaming plate structure three regards
Figure.Fig. 8 is the front view of air duct coaming plate.Under a kind of crimping kitchen ventilator air duct, including air duct coaming plate 1, air duct upper cover plate 2, air duct
Cover board 3, air duct upper cover plate 2 and air duct lower cover 3 distinguish the both sides that fixing seal is mounted on air duct coaming plate 1 so that air duct coaming plate
1, air duct upper cover plate 2, air duct lower cover 3 constitute a hollow space, are connected for air.Driving motor is enclosed mounted on air duct
Inside plate 1, and in the hollow space.Wherein, air duct coaming plate 1 includes coaming plate wall 13 and front shoe 14, preceding fixation
Plate 14 is fixed on the front side of coaming plate wall 13, rectangular in 14 middle part setting of front shoe for the fixed shape for maintaining coaming plate wall 13
Opening, passes through for air.It is provided with the first washer 11 on front shoe 14, it is right respectively on the first washer 11 and front shoe 14
Front bolt hole 12 should be set, wherein the first washer 11 is made of fine and close soft material, can be rubber skin.By in front bolt
Installation bolt on hole 12, for the kitchen ventilator air duct of the present invention to be connected to external air duct, so as to external air duct
Exhaust.By the way that the first washer 11 is arranged on front shoe 14, it is used for the tensioning of above-mentioned installation bolt, avoids making for a long time
Used time, fixing bolt pitch；Additionally by the first washer 11, ensure that when front shoe 14 is fixed sealing can be played the role of again,
It avoids moving air from leaking, influences smoke discharging effect.
Wherein, coaming plate wall 13 includes upper straightway siding 131, circular arc siding 132 and lower straightway siding 133, upper straight line
Section siding 131 and lower straightway siding 133 are separately fixed at the both ends of circular arc siding 132 and tangent with circular arc siding 132 respectively.
Wherein, upper straightway siding 131, circular arc siding 132 and lower straightway siding 133 are made by a monoblock sheet metal component bending.
Upper cover plate 2 flat shape in air duct is consistent with the end surface shape of coaming plate wall 13, is enclosed so as to which air duct upper cover plate 2 to be completely installed to
The end surface side of wooden partition 13.Round first air inlet 23 of border circular areas setting of upper cover plate 2 in air duct, in round first air inlet 23
Periphery is provided with upper bolt hole 22 in the outer part, by the way that bolt is arranged on upper bolt hole 22 for wind loop to be fixedly mounted.
Lower cover 3 shape in air duct is consistent with the end surface shape of coaming plate wall 13, is arranged in the border circular areas of air duct lower cover 3
Second air inlet 32 is used for from lower side inspiration oil smoke.By the collective effect of the first air inlet 23 and the second air inlet 32, increase
The effect of fume-exhausting is added.Outside coaming plate flanging 15 is arranged in the both sides of the coaming plate wall 13, and the coaming plate flanging 15 is
It is folded up to form flanging on the basis of former coaming plate wall 13.Corresponding, in air duct, the periphery of upper cover plate 2 and air duct lower cover 3 is set
Cover board crimping 25 and cover board card slot 26 are set, the cover board card slot 26 is on original air duct upper cover plate 2 and air duct lower cover 3
The groove being stamped and formed out.When air duct upper cover plate 2 and air duct lower cover 3 to be mounted on air duct coaming plate 1, first by coaming plate wall 13
The outer wall of cover board card slot 26 is blocked in lower surface, is then carried out at crimping to air duct upper cover plate 2 and 3 periphery of air duct lower cover respectively
Reason so that air duct upper cover plate 2 and 3 periphery of air duct lower cover form cover board crimping 25 so that cover board crimping 25 is by coaming plate flanging 15
It wraps.Due to the supporting role of 26 outer wall of cover board card slot, prevent coaming plate wall 13 from falling off downwards because of its own gravity or surprisingly, together
When, since coaming plate flanging 15 is clasped by cover board crimping 25, limitation air duct coaming plate 1 is relative to air duct upper cover plate 2 and air duct lower cover 3
Move left and right, additionally by coaming plate flanging 15 on coaming plate wall 13 respectively with the installation of cover board crimping 25, cover board card slot 26 coordinate,
Coaming plate wall 13 has with air duct upper cover plate 2, air duct lower cover 3 in sealing contact at three respectively, so as to enhance sealing effect, prevents
Gas leakage when work does not have to extra soldered in addition it can the intensity of enhancing structure, ensure that the appearance cleaning of the present invention.It is logical
Drop test is crossed, the present invention will not fall apart, and sealing effect influences less.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, in relation to the common of technical field
Technical staff can also make a variety of changes and modification without departing from the spirit and scope of the present invention, therefore all
Equivalent technical solution also belongs to scope of the invention, and scope of patent protection of the invention should be defined by the claims.
