Description
Technical field
The present invention relates to a kind of exhaust duct, and in particular to a kind of oil smoke road reverse-filling air draft bend pipe.
Background technology
With the development and the improvement of people's living standards of society, in order to prevent from cooking caused fume pollution kitchen ring
Border, many families can install range hood in kitchen, siphon away the oil smoke in kitchen in cooking process.Existing high residential building
In kitchen ventilation road use common flue more, when certain family fume exhauster for kitchen does not work, the oil smoke in common flue is easy
The exhaust duct exported by range hood pours in down a chimney and entered in residential households kitchen, asking for food taint of odour and fume pollution occurs
Topic.In order to prevent oil smoke from pouring in down a chimney, return taste, Kitchen hygiene environment is effectively improved, existing technical measures are set at exhaust duct
Non-return valve gear.When range hood normal work, check (non-return) valve is opened under the effect of air-flow；And work as range hood not work
When making, check (non-return) valve is closed so as to prevent the oil smoke of common flue from pouring in down a chimney under gravity.But due to residential housing
More and more higher, common flue operating condition become increasingly complex, and the pressure in flue is also increasing；On the other hand, with non-return
The growth of valve usage time, the non-return performance of its closure is also more and more weaker, has had a strong impact on that exhausting-pipe for cooking fume exhauster road is normal
Air draft and only wind function, therefore be badly in need of designing and a kind of can alleviate the exhaust duct that oil smoke pours in down a chimney and seem of crucial importance and must
Will.
The content of the invention
The shortcomings that it is an object of the invention to overcome above-mentioned prior art, there is provided a kind of oil smoke road reverse-filling air draft is curved
Pipe, the air draft bend pipe can prevent oil smoke from pouring in down a chimney.
To reach above-mentioned purpose, reverse-filling air draft bend pipe in oil smoke road of the present invention includes main channel, the first auxiliary is led to
Road and the second accessory channel, main channel are arc-shaped structure, and the first accessory channel is cirque structure, and the right-hand member of main channel is set
There is oil smoke entrance, the left end of main channel is provided with oil smoke outlet, and the lateral surface of main channel offers the first oil smoke mouth, main channel
Medial surface is provided with the second oil smoke mouth, wherein, the entrance of the first accessory channel is connected with the first oil smoke mouth, the second auxiliary
The entrance of passage is connected with the second oil smoke mouth, the first accessory channel and the second accessory channel along flue gas forward flow direction successively
Distribution；
First accessory channel is connected the inwall on the right side of the accessory channel of opening position first and the inwall of main channel with main channel
Between be in inverted V-shaped structure, the second accessory channel and the inwall on the right side of the accessory channel of opening position second that main channel is connected and master
It is in inverted V-shaped structure between the inwall of passage；
First accessory channel is connected the inwall on the left of the accessory channel of opening position first and the inwall of main channel with main channel
Between angle be θ, the second accessory channel and the inwall on the left of the accessory channel of opening position second that main channel is connected with it is main logical
Angle between the inwall in road is ρ, wherein, 90 ° of 180 ° of ＜ θ ＜, 90 ° of 180 ° of ＜ ρ ＜.
Branching block is provided with main channel, the cross section of branching block is to be spliced by the first triangle and the second triangle
Shape, wherein, the drift angle of the first triangle is located at the side of main channel oil smoke entrance, and the drift angle of the second triangle is positioned at main logical
The side of road oil smoke outlet, and the drift angle of the first triangle is acute angle, the drift angle of the second triangle are obtuse angle, the first triangle and
Second triangle is sequentially distributed along the direction that oil smoke circulates.
The entrance of the accessory channel of branching block face second.
The invention has the advantages that：
Reverse-filling air draft bend pipe in oil smoke road of the present invention is in specific operation process, when range hood works, i.e.,
When oil smoke forward flow, due to the inwall that the first accessory channel is connected with main channel on the right side of the accessory channel of opening position first with
It is in inverted V-shaped structure between the inwall of main channel, the accessory channel of opening position second that the second accessory channel is connected with main channel is right
It is in inverted V-shaped structure, i.e. inwall on the right side of the first accessory channel and the inwall of main channel between the inwall of side and the inwall of main channel
It is non-to seamlessly transit, the inwall for the accessory channel of opening position second that the inwall on the right side of the second accessory channel is connected with main channel
It is non-to seamlessly transit, therefore the oil smoke in main channel directly flows through main channel with certain flow direction, without entering first
In accessory channel and the second accessory channel；When range hood is stopped, i.e., oil smoke reverse flow when, oil smoke is from main channel
Oil smoke outlet is entered in main channel, due to 90 ° of 108 ° of ＜ θ ＜, 90 ° of 108 ° of ＜ ρ ＜, therefore it is interior on the left of the first accessory channel
Wall and the interior walls be smooth transition of main channel, the interior walls be smooth transition of inwall and main channel on the left of the second accessory channel, therefore oil
Cigarette is divided into two-way in flow process, wherein oil smoke flows in main channel all the way, another way enter the first accessory channel and
In second accessory channel, therefore oil smoke flow inversion after the first accessory channel and the second accessory channel changes, Ran Houyu
Oil smoke in main channel reversely mixes and interferes with each other obstruction, so as to prevent oil smoke from entering in the oil smoke entrance of main pipeline, and then
Prevent oil smoke from pouring in down a chimney, simple in construction, easy to operate, applicability is extremely strong, can effectively solve the problem that high residential building resident family lampblack-preventing pours in down a chimney
And the taint of odour that occurs in cooking process of different home and anti-taste problem, improve family kitchen environment and quality.
