Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and in particular to an exhaust pipe and a range hood using the exhaust pipe. Background Technology

[0002] To facilitate portability and installation, most range hoods on the market use flexible, extendable corrugated hoses, typically made of materials such as aluminum foil, steel wire, plastic, or pure aluminum.

[0003] For example, Chinese utility model patent application 201922242929.6 discloses an exhaust mask and smoke exhaust pipe assembly for a range hood. The smoke exhaust pipe is located at the outlet of the exhaust mask. The smoke exhaust pipe 2 includes an aluminum foil tube 21, and steel wire is spirally wound around the outer periphery of the aluminum foil tube 21.

[0004] The aluminum foil cigarette tubes used in the market typically have a larger spacing between the steel wires. (See...) Figure 1 The spacing between two adjacent turns of steel wire is P1, and P1 is greater than or equal to 24mm, which increases the compression ratio of the flue pipe, thereby reducing the volume of the flue pipe and saving product packaging space and costs. During installation, when the flue pipe is pulled open, there are usually obvious wrinkles, which increases the smoke exhaust resistance, reduces the smoke exhaust effect, and increases the smoke exhaust noise. Oil can easily accumulate at the wrinkles, posing a safety hazard. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a smoke exhaust pipe with a smaller wire spacing to address the shortcomings of the existing technology, thereby reducing the disadvantages of high wind resistance and high smoke exhaust noise of the existing smoke exhaust pipe, and reducing the amount of oil accumulation at the folds of the smoke exhaust pipe.

[0006] The second technical problem to be solved by this utility model is to provide a range hood that uses the exhaust pipe.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a smoke exhaust pipe, including a smoke exhaust pipe body with aluminum foil and a steel wire that is wound around the smoke exhaust pipe body to provide support, characterized in that: the distance between two adjacent turns of the steel wire on at least part of the smoke exhaust pipe body is P, and satisfies 12mm≤P≤18mm.

[0008] By reducing the spacing of the steel wires, the drawbacks of existing exhaust pipes, such as high wind resistance and loud exhaust noise, are reduced, as is the amount of oil accumulated at the folds of the exhaust pipes.

[0009] In order to protect the exhaust pipe body and reduce airflow noise, the exhaust pipe also includes a protective layer that can protect the exhaust pipe body and reduce airflow noise. The protective layer is disposed on the outside of the exhaust pipe body.

[0010] To protect the exhaust pipe body and reduce airflow noise, the protective layer is a plastic film with at least one layer.

[0011] To reduce the smoke exhaust resistance and noise in the bend section, the smoke exhaust pipe body includes a straight section and a bend section, and the spacing of the steel wires in the bend section is P.

[0012] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a range hood that uses the exhaust pipe.

[0013] Compared with the prior art, the advantages of this utility model are: by reducing the spacing of the steel wires, the disadvantages of the existing exhaust pipes, such as high wind resistance and high exhaust noise, are reduced, and the amount of oil accumulation at the folds of the exhaust pipe is reduced.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0020] Example 1

[0021] See Figure 4 A range hood includes an output end 21, at which an exhaust pipe is connected.

[0022] See Figure 2 The exhaust pipe includes an aluminum foil exhaust pipe body 11 and a steel wire 12 wound around the exhaust pipe body 11 for support. The steel wire 12 is spirally wound around the perimeter of the exhaust pipe body 11, and the distance between two adjacent turns of the steel wire 12 is P, which satisfies 12mm≤P≤18mm.

[0023] To avoid excessive cost increases, the diameter of the steel wire 12 can be appropriately reduced, while still achieving the desired support effect for the aluminum foil.

[0024] By reducing the spacing of the steel wires, the drawbacks of existing exhaust pipes, such as high wind resistance and loud exhaust noise, are reduced, as is the amount of oil accumulated at the folds of the exhaust pipes.

[0025] Example 2

[0026] See Figure 3 The exhaust pipe also includes a protective layer 13, which is disposed on the outside of the exhaust pipe body 11. The protective layer 13 is a plastic film with at least one layer, and can be a plastic film with good sound insulation properties, such as PVC or PE. The protective layer 13 can protect the exhaust pipe body 11 and also has a certain sound insulation effect on airflow noise, reducing the amount of exhaust airflow noise radiated into the kitchen, reducing the impact on users, and thus improving the user experience.

[0027] Example 3

[0028] See Figure 4 The exhaust pipe body 11 includes a straight section 111 and an elbow section 112, with the elbow section 112 connecting the straight section 111 and the output end 21. Because the wind resistance at the elbow section 112 is relatively high, significantly impacting the exhaust resistance and noise of the range hood, a small wire spacing is used at the elbow section 112. The spacing between two adjacent turns of the wire 12 on the elbow section 112 is P, where 12mm ≤ P ≤ 18mm. The spacing between two adjacent turns of the wire 12 on the straight section 111 remains at the normal spacing. Figure 1 In the existing technology, the spacing of the steel wires 12 in the straight section 111 is P1, 24mm≤P1≤28mm.

[0029] The above embodiments can be freely combined and used according to needs.
