Abstract
The utility model discloses an outer flue of arranging of hidden, include the pipe of discharging fume the pipe butt joint with the lampblack absorber, its characterized in that: the window is characterized by further comprising a rectangular flat pipe, one end of the round pipe is connected with one end of the rectangular flat pipe into a whole through a smooth transition part, and the rectangular flat pipe penetrates through the building outer wall to be hidden in a structure dividing line or is placed in a gap between the top end of the window and the window hole. Compared with the prior art, the utility model discloses abandon shared flue, stop the taint of odor phenomenon, can will when building a wall or installing door and window the utility model discloses the outlet flue is hidden in the structure and cuts apart the gap between line or window top and the window hole, from outdoor unable outer row's flue of seeing, is favorable to the city to hold neatly, and unified standard prevents in disorder to arrange and puts.
Description
Technical Field
The utility model belongs to the technical field of building structure, in particular to flue is arranged outward to hidden.
Background
At present, the kitchen of residential buildings is generally provided with a common flue for discharging oil smoke of an oil smoke exhauster, and a flue cavity of the common flue penetrates through a plurality of floors to be communicated with each household of the same unit, but the common problems of the flues are that the odor is mixed with each other, and what dishes are known about upstairs and downstairs when one household is used for cooking dishes; therefore, at present, most families return to a mode of punching holes in windows or walls and directly exhausting, the diameter of a smoke exhaust pipe of the range hood is mainly 20cm, 18cm, 16cm and 15cm, holes are punched in the walls in some cases, and the size of the smoke exhaust pipe is different from that of the smoke exhaust pipe in the window, so that the outdoor smoke exhaust pipe is seven-horizontal-eight-vertical-eight in the transverse direction and is very unattractive.
SUMMERY OF THE UTILITY MODEL
Stifled not as dredging, the utility model aims at disclosing one kind and abandoning traditional sharing flue under the condition that does not influence the whole outward appearance of building, changing into the outer flue of hidden of direct drainage mode, the technical scheme who takes is:
the utility model provides an outer flue of arranging of hidden, includes the pipe of the butt joint of tub of discharging fume with the lampblack absorber, its characterized in that: the window is characterized by further comprising a rectangular flat pipe, one end of the round pipe is connected with one end of the rectangular flat pipe into a whole through a smooth transition part, and the rectangular flat pipe penetrates through the building outer wall to be hidden in a structure dividing line or is placed in a gap between the top end of the window and the window hole. Compared with the prior art, the utility model discloses abandon shared flue, stop the taint of odor phenomenon, can will when building a wall or installing door and window the utility model discloses the outlet flue is hidden in the structure and cuts apart the gap between line or window top and the window hole, from outdoor unable outer row's flue of seeing, is favorable to the city to hold neatly, and unified standard prevents in disorder to arrange and puts.
Furthermore, a vertical plate which is connected with the rectangular flat tube and the smooth transition part into a whole is arranged at the upper end of the rectangular flat tube, which is close to the smooth transition part, the vertical plate can be abutted against an inner wall surface and is provided with two fixing holes for allowing fastening screws to pass through, and a plurality of reinforcing ribs are arranged at the joint of the vertical plate and the smooth transition part. Is beneficial to enhancing the strength and preventing the fracture.
Furthermore, the circular tube comprises four sections of which the outer diameters are gradually reduced, and can be respectively butted with smoke exhaust pipes of the range hoods with the diameters of 20cm, 18cm, 16cm and 15 cm. The range hoods of different models can be conveniently used.
Furthermore, the vertical ribs which are connected with the upper side and the lower side into a whole are uniformly arranged in the tube cavity of the rectangular flat tube. The compressive strength of the rectangular flat tube is enhanced, and collapse is prevented.
Further, the length of the rectangular flat pipe is 100-120cm, the width is 36cm, the height is 3cm, and the wall thickness of the rectangular flat pipe and the wall thickness of the round pipe are 3 mm. The height is thin enough and is suitable for concealment.
Drawings
Fig. 1 is a schematic structural view of embodiment 1.
Fig. 2 is a schematic structural view of embodiment 2.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The theoretical basis that the embodiment can realize normal smoke discharge is discussed through calculation as follows:
according to the minimum pipe diameter of 15cm of the smoke exhaust pipe, the air carrying area m is as follows:
m=πR2=3.14*7.5*7.5=176.625cm2；
the wind carrying area n of the rectangular flat pipe is as follows:
n = length height-wall thickness and area of vertical ribs =100 x 3- (306 x 0.3+11 x 2.4 x 0.3) =200.28 cm2；
From the above calculation, the wind carrying area of the rectangular flat tube is larger than that of the smoke exhaust tube, so that the rectangular flat tube cannot exhaust smoke of the range hood to form wind resistance, and smooth smoke exhaust can be realized. Moreover, the rectangular flat tube cavity is very thin, birds cannot enter the rectangular flat tube cavity, and rainwater cannot flow into the rectangular flat tube cavity easily.
The embodiment 2 is otherwise the same as the embodiment 1, except that a vertical plate 4 connected with the rectangular flat tube 2 and the smooth transition part 3 into a whole is arranged at the upper end of the rectangular flat tube 2 near the smooth transition part 3, the vertical plate 4 can be abutted against an inner wall surface and is provided with two fixing holes 41 for allowing fastening screws to pass through, and a plurality of reinforcing ribs 42 are arranged at the joint of the vertical plate 4 and the smooth transition part 3.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
