Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a strip component and a range hood. Background Art

[0002] As people's quality of life improves, their expectations for kitchen cooking environments are also growing. Range hoods have become an indispensable kitchen appliance in modern homes. A range hood uses a motor to drive the impeller at high speed, creating a negative pressure zone near the smoke collection chamber, drawing fumes into the hood and exhausting them outdoors.

[0003] Range hoods typically don't have components installed at their air inlets, leaving them hollow and affecting the overall aesthetics. Currently, strips are often installed at the air inlets to block them. While this solves the problem of a hollow air inlet, it compromises air intake and is inconvenient to install and remove. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a strip assembly is provided, and the technical solution is as follows.

[0005] The strip assembly includes a strip and a connecting piece, the strip has a front side and a back side, the connecting piece is arranged on the back side, wherein the connecting piece has a connecting body and a claw, the connecting body is connected to the back side, and the claw extends from the connecting body toward away from the front side.

[0006] When the strip assembly of the utility model is applied to a range hood, since the strip has a back side portion, a connecting piece with a claw is provided on the back side portion. The claw is provided on the back side portion and will not block the air intake of the range hood. At the same time, the front side portion can partially block the air intake, thereby improving the aesthetics of the entire machine. In addition, the strip can be quickly disassembled and assembled by the claw, and the structure is simple and easy to operate.

[0007] For example, the strip-shaped member comprises a first inclined portion, a second inclined portion, and a curved transition portion. The first and second inclined portions are connected by the curved transition portion, which forms the front portion. This structure is simple and easy to manufacture. When the strip-shaped member is applied to a range hood, it ensures smooth inhalation and a good air intake.

[0008] For example, the first inclined portion has a first end and a second end, the second inclined portion has a third end and a fourth end, the back portion is formed between the first and third ends, the arcuate transition portion connects between the second and fourth ends, and in the height direction, the first and third ends are separated by a distance H1, and the second and third ends are separated by a distance H2, where H1 < H2. When distances H1 and H2 have this relationship, oil residue on the strip can flow down along the first and second inclined portions. When the strip assembly is applied to a range hood, the oil flowing down along the first and second inclined portions can be directed into the oil cup below, preventing oil dripping during prolonged use.

[0009] For example, the first inclined portion and the second inclined portion have an included angle α, 25°≤α≤45°. Setting the included angle α between the first and second inclined portions within this range allows oil to flow smoothly downward along the first and second inclined portions. Furthermore, when the strip assembly is applied to a range hood, it can adapt to the housing, ensuring that oil dripping from the bottom of the first and second inclined portions is directed into the oil cup below the housing.

[0010] For example, the claw has multiple claw bodies, each of which has a first extension section and a second extension section. The first extension section extends in a different direction than the second extension section. The first extension section has a connection point away from the connecting body, and the second extension section bends and extends from the connection point. This connection point forms the claw body into two sections extending in different directions, ensuring secure installation and preventing the claw from falling off.

[0011] For example, the connection points of the plurality of claws are formed on the same circle with a diameter of D1. This facilitates the installation of the claws, ensures the firmness of the claws during installation, and avoids the occurrence of the claws falling off.

[0012] For example, the second extension has a distal end point away from the first extension, and the distal ends of the multiple claws are formed on a common circle with a diameter D2, where D2 ≤ D1. This relationship between diameters D1 and D2 facilitates the installation of the claws, effectively ensuring a secure installation and preventing them from falling off.

[0013] For example, the claw comprises a mounting plate with an opening formed therein, and a plurality of claw bodies disposed on the mounting plate and spaced circumferentially around the opening. Thus, the claw is connected to the connecting body via the mounting plate, facilitating installation of the claw. The plurality of claw bodies disposed on the mounting plate and spaced circumferentially around the opening effectively ensure the structural strength of the claw and its secure installation.

[0014] For example, the strip assembly has at least two connecting pieces, which are spaced apart along the length of the strip assembly, thereby ensuring the firmness of the strip assembly during installation.

[0015] According to another aspect of the present invention, a range hood is provided, comprising a housing, a flap assembly, and the aforementioned strip assembly. The housing is provided with a first air inlet and a second air inlet, the first air inlet being located above the second air inlet and being opened or closed by the flap assembly. The housing is provided with mounting holes around the second air inlet, and claws are connected to the mounting holes so that the strip assembly partially covers the second air inlet. Because the aforementioned strip assembly has the aforementioned beneficial effects, a range hood including the aforementioned strip assembly also has the aforementioned beneficial effects, which will not be further elaborated herein.

[0016] The Summary of the Utility Model introduces a series of simplified concepts, which will be further described in detail in the Detailed Description of the Utility Model. This Summary of the Utility Model does not intend to limit the key features and essential technical features of the claimed technical solution, nor does it intend to determine the scope of protection of the claimed technical solution.

[0029] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0030] To thoroughly understand the embodiments of the present invention, a detailed structure will be provided in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0031] An embodiment of the present invention provides a strip assembly. The strip assembly provided by the present invention can be used in a range hood. The following will describe in detail a strip assembly according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0032] See also Figures 5 to 7The strip assembly 10 may include a strip 110 and a connector 120. The strip 110 may have a front side portion 111 and a back side portion 112. The connector 120 may be disposed on the back side portion 112. The connector 120 may include a connecting body 121 and a claw 122. The connecting body 121 may be connected to the back side portion 112. The claw 122 may extend from the connecting body 121 in a direction away from the front side portion 111. Figure 2 When the strip assembly 10 is applied to the range hood 1 , the front side portion 111 is located on the side close to the operator.

[0033] When the strip assembly 10 of the present invention is applied to the range hood 1, since the strip 110 has a back portion 112, the back portion 112 is provided with a connecting member 120 with a claw 122. The claw 122 is provided on the back portion 112 and will not block the air intake of the range hood 1. At the same time, the front portion 111 can partially block the air intake, thereby improving the aesthetics of the entire machine. In addition, it can be quickly disassembled and assembled through the claw 122, and the structure is simple and easy to operate.

[0034] The claw 122 can be connected to the connecting body 121 by means of rivets or welding. Of course, the claw 122 can also be connected to the connecting body 121 by other means such as screw connection. The claw 122 can also be integrally formed with the connecting body 121. In some embodiments, the claw 122 can be made of spring steel. Specifically, the claw 122 can be made of 65 manganese steel. 65 manganese steel is not only relatively low in price, saving processing costs, but also has high structural strength, certain toughness and plasticity after heat treatment, which ensures the effect of the claw 122 while extending the service life of the claw 122. The connecting body 121 can be connected to the strip 110 by means of welding, gluing, etc., so as to facilitate the installation of the strip 110.

[0035] See also Figures 1 to 6 The strip 110 may have a first inclined portion 113, a second inclined portion 114, and a curved transition portion 115. The first inclined portion 113 and the second inclined portion 114 may be connected by the curved transition portion 115. The curved transition portion 115 may form the front portion 111. This structure is simple and easy to manufacture. When the strip assembly 10 is applied to the range hood 1, it can ensure smooth inhalation and ensure effective air intake.

[0036] In an embodiment not shown in the figures, the strip 110 can be configured as a solid structure, in which case the structural strength of the strip 110 is higher. Understandably, the first inclined portion 113, the second inclined portion 114, the arc-shaped transition portion 115 and the back portion 112 can be respectively a first inclined surface, a second inclined surface, a front surface and a back surface of the strip 110. In this case, the connecting body 121 can be connected to the back surface. In some embodiments, the strip 110 can also be configured as a hollow structure, in which case the structure of the strip 110 is simpler and easier to manufacture. Specifically, when the strip 110 is configured as a hollow structure, in combination with reference to Figures 3 to 6 , the first inclined portion 113, the second inclined portion 114 and the arc-shaped transition portion 115 can be configured as plate-shaped members, and the back portion 112 can be configured as an opening, in which case the connecting body 121 can be arranged at the opening and connected to the first inclined portion 113 and the second inclined portion 114. In an embodiment not shown in the figures, the back portion 112 can also be configured as a plate-shaped member, in which case the back portion 112 can be connected to the first inclined portion 113 and the second inclined portion 114 by welding, one-piece forming or the like. The back portion 112, the first inclined portion 113 and the second inclined portion 114 can be enclosed to form a special-shaped tubular structure. The connecting body 121 can be connected to the side of the back portion 112 away from the front portion 111 by welding, sticking or the like. Specifically, when the strip 110 is configured as a hollow structure, it can be made by bending a metal member. The strip 110 is made of metal, which can avoid the problem of oil sticking. Of course, the strip 110 can also be manufactured by other means or made of other materials.

[0037] In combination with reference to Figures 3 to 6The first inclined portion 113 can have a first end 1131 and a second end 1132. The second inclined portion 114 can have a third end 1141 and a fourth end 1142. The back portion 112 can be formed between the first end 1131 and the third end 1141. The arc-shaped transition portion 115 can be connected between the second end 1132 and the fourth end 1142, and in the height direction, the first end 1131 and the third end 1141 can have a distance H1. The second end 1132 and the third end 1141 can have a distance H2, H1

[0038] Again in combination with reference to Figures 3 to 6 The first inclined portion 113 and the second inclined portion 114 can have an included angle a, 25°≤a≤45°. For example, the included angle a can be 25°, 35°, 45°, etc. The included angle a between the first inclined portion 113 and the second inclined portion 114 is set in this range, on the one hand, the oil stains can flow smoothly along the first inclined portion 113 and the second inclined portion 114 to the lower side, on the other hand, when the strip assembly 10 is applied to the range hood 1, it can be adapted to the shell 20, and ensure that the oil stains falling from the lower part of the first inclined portion 113 and the oil stains falling from the lower part of the second inclined portion 114 can be guided to the oil cup 40 below the shell 20. In an embodiment of the present application, the included angle a is 25°, at this time, on the one hand, the oil stains can effectively flow smoothly along the first inclined portion 113 and the second inclined portion 114 to the lower side, on the other hand, when the strip assembly 10 is applied to the range hood 1, it can be adapted to the shell 20, and effectively ensure that the oil stains falling from the lower part of the first inclined portion 113 and the oil stains falling from the lower part of the second inclined portion 114 can be guided to the oil cup 40 below the shell 20.

[0039] In combination with reference to Figures 3 to 7The claw 122 can have a plurality of claw bodies 1221. Each claw body 1221 can have a first extension section 1221a and a second extension section 1221b. The extension direction of the first extension section 1221a can be different from the extension direction of the second extension section 1221b, and the first extension section 1221a can have a connecting point 1221c away from the connecting body 121. The second extension section 1221b can extend from the connecting point 1221c. In this way, the claw body 1221 is formed into two sections with different extension directions through the connecting point 1221c, ensuring the firmness of the claw 122 during installation and avoiding the claw 122 from falling off. The claw body 1221 can be four. At this time, the firmness of the claw 122 during installation is effectively ensured, and materials are saved. Of course, it is not excluded that the claw body 1221 can be two, three, five, etc.

[0040] Again, see Figures 3 to 7 The connecting points 1221c of the plurality of claw bodies 1221 can be formed on the same circle with a diameter D1. In this way, it is convenient to install the claw 122, ensuring the firmness of the claw 122 during installation and avoiding the claw 122 from falling off. Understandably, the claw 122 at this time is adapted to a round hole. In the embodiments not shown in the figure, it is not excluded that the connecting points 1221c of the plurality of claw bodies 1221 can be formed on the same square, and the claw 122 at this time can be adapted to a square hole.

[0041] Again, see Figures 3 to 7 The second extension section 1221b can have a distal end point 1221d away from the first extension section 1221a. The distal end points 1221d of the plurality of claw bodies 1221 can be formed on the same circle with a diameter D2, D2≤D1. When the diameter D1 and the diameter D2 have this relationship, it is convenient to install the claw 122, effectively ensuring the firmness of the claw 122 during installation and avoiding the claw 122 from falling off. In the embodiments not shown in the figure, in the case where the connecting points 1221c of the plurality of claw bodies 1221 can be formed on the same square, the distal end points 1221d of the plurality of claw bodies 1221 can also be formed on the same square to adapt to the square hole. Understandably, the square on which the connecting points 1221c are formed can be consistent with the square on which the distal end points 1221d are formed, and the perimeter of the square on which the connecting points 1221c are formed is not less than the perimeter of the square on which the distal end points 1221d are formed.

[0042] Again, see Figures 3 to 7The claw 122 may have a mounting plate 1222. An opening 1222a may be provided on the mounting plate 1222. A plurality of claw bodies 1221 may be provided on the mounting plate 1222 and spaced circumferentially around the opening 1222a. In this way, the claw 122 is connected to the connecting body 121 via the mounting plate 1222, which facilitates the installation of the claw 122. The plurality of claw bodies 1221 are provided on the mounting plate 1222 and spaced circumferentially around the opening 1222a, effectively ensuring the structural strength of the claw 122 and the firmness of the claw 122 during installation. The mounting plate 1222 may be connected to the connecting body 121 by rivets or welding. Of course, the mounting plate 1222 may also be connected to the connecting body 121 by other means such as screw connection. The mounting plate 1222 may also be integrally formed with the connecting body 121.

[0043] See also Figure 5 and Figure 8 , the strip assembly 10 may have at least two connectors 120. The at least two connectors 120 may be arranged along the length direction of the strip 110 (i.e. Figure 5 The strip assembly 110 may be arranged at intervals (in the XX direction). For example, the number of connectors 120 may be two, three, or four. This ensures the secure installation of the strip assembly 10. In some embodiments, there may be three connectors 120. Specifically, the three connectors 120 may be provided at both ends and in the middle of the strip assembly 110, effectively ensuring the secure installation of the strip assembly 10.

[0044] According to another aspect of the present invention, a range hood 1 is provided. The range hood 1 may include a housing 20, a flap assembly 30, and the strip assembly 10 described above. The housing 20 may be provided with a first air inlet 210 and a second air inlet 220. The first air inlet 210 may be located above the second air inlet 220. The first air inlet 210 may be opened or closed by the flap assembly 30. The housing 20 is provided with mounting holes 230 around the second air inlet 220. The claws 122 are connected to the mounting holes 230 so that the strip assembly 10 partially blocks the second air inlet 220. Since the strip assembly 10 described above has the above-mentioned beneficial effects, the range hood 1 including the strip assembly 10 described above also has the above-mentioned beneficial effects, which will not be described in detail here.

[0045] Furthermore, after the range hood 1 adopts the strip assembly 10 of the above embodiment, even if the strip assembly 10 is covered with oil due to long-term use, it can be quickly disassembled and cleaned based on the setting of the claws 122 .

[0046] See also Figure 1 、 Figure 3 and Figure 8In some embodiments, the housing 20 may include a housing body 201 and an air inlet mesh 202. The air inlet mesh 202 may be disposed below the first air inlet 210. The air inlet mesh 202 may be provided with a second air inlet 220 and mounting holes 230. The number of mounting holes 230 may be the same as the number of connectors 120. The strip assembly 10 may be installed by connecting the claws 1221 to the mounting holes 230, allowing the strip 110 to partially block the second air inlet 220, thereby improving the aesthetics of the range hood 1.

[0047] Specifically, the diameter of the mounting hole 230 can be smaller than D1 to engage the claw 122. During the installation of the claw 122 on the air inlet grille 202, the second extension section 1221b first partially extends into the mounting hole 230. As the second extension section 1221b continues to extend deeper, the claw body 1221 is squeezed by the sidewall of the mounting hole 230, reducing the diameter of the circle containing the multiple connection points 1221c. This allows the claw 1221c to be easily passed through the mounting hole 230. After the circle containing the multiple connection points 1221c passes through the mounting hole 230, the claw 122 is installed, the claw body 1221 is no longer squeezed by the mounting sidewall, and the diameter of the circle containing the multiple connection points 1221c returns to D1, thereby engaging the claw 122 and preventing the claw 122 from falling out of the mounting hole 230. During the process of removing the claw 122 from the air inlet mesh 202, a force is applied to the claw 122, and the claw body 1221 is squeezed by the side wall of the mounting hole 230, so that the diameter of the circle where the multiple connection points 1221c are located is reduced, so that the circle where the multiple connection points 1221c are located can be easily passed through the mounting hole 230. After the circle where the multiple connection points 1221c are located passes through the mounting hole 230, the claw 122 is removed. When the user installs the strip component 10, he only needs to align the claw 122 with the mounting hole 230, and then forcefully press the claw 122 into the mounting hole 230 to complete the installation of the strip component 10. When the user disassembles the strip component 10, he only needs to forcefully pull the claw 122 outward to complete the disassembly of the strip component 10. This disassembly and assembly method is convenient and quick.
