Description

Technical Field

[0001] The utility model relates to the field of integrated stoves, in particular to an oil leakage-proof connecting pipe used for an air duct of an integrated stove. Background Art

[0002] The integrated stove includes a stove body and an air duct system. The oil in the air duct system will flow into the oil box. The air duct system needs to use a telescopic hose to lead the oil smoke in the air duct to the outside. However, since the connection between the telescopic hose and the air duct is a clamp, and some are wrapped with a circle of aluminum foil tape, the oil in the oil smoke will still flow out from the gap between the hose and the air duct, dirtying the ground. Summary of the invention

[0003] The object of the present invention is to provide an oil leakage-proof connecting pipe for an integrated stove air duct, which can lead the oil leaking from the connection between the hose and the air duct back into the integrated stove air duct.

[0004] To achieve this purpose, the present invention adopts the following technical solution: an oil leakage prevention connecting pipe for an integrated stove air duct, comprising a pipe body, the pipe body having a smoke inlet end connected to the integrated stove air duct and a smoke outlet end connected to the oil smoke exhaust hose, the bottom of the smoke inlet end forms a downwardly inclined portion that is inclined downward in the smoke inlet direction, the downwardly inclined portion forms a first opening, the lower edge of the first opening is provided with a first guide plate extending to the bottom of the connection between the oil smoke exhaust hose and the smoke outlet end, the first guide plate is an inclined plate, and one downwardly inclined end of the inclined plate is connected to the first opening. When in use, the oil leaked between the smoke outlet end and the smoke exhaust hose will drip onto the first guide plate, and then flow back into the integrated stove air duct along the inclined direction of the first guide plate, thereby avoiding dirtying the ground.

[0005] Furthermore, the first guide plate has an outer periphery that tilts upwards, so as to prevent oil from leaking from the outer periphery of the inclined plate.

[0006] Furthermore, the upper edge of the first opening forms a second guide plate that is inclined downward toward the smoke inlet direction, and the lower end of the second guide plate is close to the middle of the first guide plate. On the one hand, the oil flows from the second guide plate to the first guide plate and then returns to the integrated stove air duct; on the other hand, the size of the first opening is reduced to reduce the blowing of oil smoke.

[0007] Furthermore, the smoke outlet end is inserted into the oil smoke exhaust hose, and further comprises a clamp which is pressed tightly on the oil smoke exhaust hose and the connection between the oil smoke exhaust hose, so as to realize the connection between the smoke outlet end and the smoke exhaust hose.

[0008] Furthermore, the smoke inlet is trumpet-shaped, and the end with a smaller opening of the smoke inlet is connected to the smoke outlet. The trumpet smoke inlet plays a role in gathering oil smoke, and increases the contact area between the smoke inlet and the oil smoke, which is conducive to the oil smoke adhering to the inner wall of the smoke inlet.

[0009] Further, an installation frame is provided around the opening of the smoke inlet end, and installation holes are opened on the installation frame as required. The installation frame can be directly installed on the outer side of the integrated stove, and the smoke inlet end faces the integrated stove air duct. The integrated stove air duct, the side of the integrated stove, and the installation holes are connected into one body by bolts.

[0010] The beneficial effects of the present utility model: The oil leaking between the smoke outlet end and the exhaust smoke hose will drip onto the first drainage plate, and then flow back into the integrated stove air duct along the inclined direction of the first drainage plate. As the oil in the integrated stove air duct flows into the oil box, it avoids soiling the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings rather than all structures. In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The exhaust smoke hose 100 is a conventional component in the art, and the integrated stove and the integrated stove air duct are existing products and are not within the protection scope of this product. As Figures 1-4As shown in the figure, the present product aims to protect an oil leakage prevention connecting pipe for an integrated stove air duct, including a pipe body 1. The pipe body 1 has a smoke inlet end 11 and a smoke outlet end 12. Among them, the smoke inlet end 11 is connected to the integrated stove air duct, and an installation frame 3 is provided around the opening of the smoke inlet end 11. The installation frame 3 is rectangular. There is an installation opening on the side of the integrated stove. The air outlet of the integrated stove air duct and the smoke inlet end 11 are both aligned with the installation opening, and then the integrated stove air duct, the installation frame 3, and the integrated stove are fixed into one body by bolts.

[0018] The smoke outlet end 12 is connected to an oil exhaust hose 100, that is, the smoke outlet end 12 is inserted into the oil exhaust hose 100. Additionally, a clamp 2 is included. The clamp 2 is also a conventional part for installing the oil exhaust hose 100, and the clamp 2 is pressed against the connection of the oil exhaust hose 100.

[0019] Furthermore, a downward inclined part 13 that inclines downward in the smoke inlet direction is formed at the bottom of the smoke inlet end 11. At this time, only the bottom surface of the smoke inlet end 11 can be set as an inclined structure, similar to an inclined plane. However, in this embodiment, the smoke inlet end 11 is in a trumpet shape. The smaller opening end of the smoke inlet end 11 is connected to the smoke outlet end 12, and the installation frame 3 is provided at the larger opening end. This trumpet-shaped smoke inlet end 11 can also play a role in gathering oil fume. The contact area between the oil fume and the smoke inlet end 11 is larger, and the effect of attaching oil is better.

[0020] Moreover, a first opening 14 is formed at the upper edge of the downward inclined part 13. Since the downward inclined part 13 is inclined, the first opening 14 is also inclined. And a first drainage plate 15 is provided at the lower edge of the first opening 14. The end of the first drainage plate 15 extends to directly below the connection of the oil exhaust hose 100 and the smoke outlet end 12. The first drainage plate 15 is an inclined plate, and the downward inclined end of the inclined plate is connected to the first opening 14. Then, the oil flowing out between the oil exhaust hose 100 and the smoke outlet end 12 will drip onto the first drainage plate 15 and flow back into the integrated stove air duct along the first drainage plate 15. To prevent the oil from flowing out of the first drainage plate, it is best to turn up the periphery of the first drainage plate 15, that is, except for the position where the first drainage plate 15 is connected to the first opening 14, the rest of the edges are bent upward. The cross-section of the first drainage plate 15 is arc-shaped.

[0021] A second drainage plate 16 is formed at the upper edge of the first opening 14. The second drainage plate 16 is inclined downward in the smoke inlet direction. The lower end of the second drainage plate 16 is close to the middle position of the first drainage plate 15. The second drainage plate 16 can not only guide the oil to the first drainage plate 15 but also further reduce the opening, thereby reducing the passage of oil fume through the opening.

[0022] In use, fume is blown from the integrated stove air duct into the pipe body 1, and then blown from the pipe body 1 to the exhaust fume hose 100 for discharge. During this process, the oil in the fume will adhere to the inner walls of the pipe body 1 and the exhaust fume hose 100, and then flow to the bottoms of the pipe body 1 and the exhaust fume hose 100 under the action of gravity. The oil leaking from between the exhaust fume hose 100 and the smoke outlet end 12 will drip onto the first drainage plate 15, and then flow back into the integrated stove air duct along the inclined direction of the first drainage plate 15, and then flow into the oil box with the oil in the integrated stove air duct for collection.

[0023] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0024] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left" and "right" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0025] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations to the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
