Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to an oil cup mounting structure and a range hood having the same. Background Technology

[0002] Range hoods are typically equipped with an oil cup to collect grease. The oil cup is installed at the bottom of the range hood body and can be removed for easy cleaning. In related technologies, the oil cup is connected to the range hood body via a hook-on method, such as... Figure 1 As shown, a hook 32 is connected to the oil cup 31. The hook 32 is used to hook and fix it to the hanging cavity a on the main body of the range hood. A limiting plate d is provided in the hanging cavity a. After the hook 32 is in place with the hanging cavity a, the limiting plate d will press the hook 32 firmly. Each time the hook 32 is inserted into or removed from the hanging cavity a, it will squeeze the limiting plate d and deform it. The limiting plate d is usually integrally injection molded with the cavity wall of the hanging cavity a. During the disassembly and assembly of the oil cup 31, the limiting plate d is easily damaged after being subjected to the squeezing force. Utility Model Content

[0003] The purpose of this utility model is to provide an oil cup mounting structure and a range hood having the same, which is used to solve the above-mentioned technical problems.

[0004] The oil cup installation structure proposed in this utility model includes a range hood body, a limiting structure, and an oil cup assembly. The range hood body has a hanging cavity with a downward-facing hanging interface. The limiting structure is connected to the range hood body, and its functional end extends into the hanging cavity. The oil cup assembly includes an oil cup and an oil cup hook. The oil cup hooks are provided on both sides of the oil cup, and the oil cup hooks have limiting parts. When the oil cup hooks move from the hanging interface into the hanging cavity, the limiting parts press the functional end of the limiting structure in the installation direction, causing the limiting structure to deform and the limiting part to pass through. After the oil cup hooks are installed in place in the hanging cavity, the functional end of the limiting structure presses the limiting part in the installation direction.

[0005] According to one embodiment of the present invention, the limiting structure includes a connecting part and a deformable part. The connecting part is connected to the main body of the smoke machine, and the cross-section of the functional end of the deformable part is V-shaped or arc-shaped.

[0006] According to one embodiment of the present invention, a connecting part is provided between the connecting part and the deformable part. The connecting part extends downward from the edge of the connecting part. The deformable part is connected to the lower edge of the connecting part. The connecting part delivers the deformable part downward and positions the functional end of the deformable part on the moving path of the oil cup hook in the hanging cavity.

[0007] According to one embodiment of the present invention, the limiting structure is a sheet metal part, and the deformation part includes a first deformation segment and a second deformation segment. The first deformation segment extends downward from the lower edge of the connecting part, and the second deformation segment extends upward from the lower edge of the first deformation segment.

[0008] According to one embodiment of the present invention, the limiting structure is a plastic part, the deformable part extends from the lower edge of the connecting part to the installation direction of the oil cup hook, and the lower surface of the deformable part is provided with a protrusion with an arc-shaped cross section along its width direction, the protrusion forming the working end.

[0009] According to one embodiment of the present invention, the working end has a first surface and a second surface that are arranged opposite to each other. When the oil cup hook is installed into the hanging cavity, the limiting part presses against the first surface, and the deforming part deforms, causing the limiting part to pass over the working end. After the oil cup hook is installed in place in the hanging cavity, the second surface presses against the limiting part in the installation direction.

[0010] According to one embodiment of the present invention, a connecting post is also provided in the hanging cavity, and the limiting structure is connected to the connecting post and located in the hanging cavity.

[0011] This utility model also proposes a range hood, which adopts the above-mentioned oil cup installation structure. The left and right sides of the main body of the range hood are connected to the blocking blocks, the hanging cavity is set on the blocking blocks, the lower surface of the blocking blocks is provided with the hanging interface, and the limiting structure is connected to the blocking blocks and the working end extends into the hanging cavity.

[0012] According to one embodiment of the present invention, the range hood also includes a back plate assembly, profiles are provided on both sides of the main body of the range hood, the back plate assembly is connected between the two profiles, and a block is connected to the lower end of the profiles.

[0013] According to one embodiment of the present invention, the smoke hood further includes a side baffle assembly. The front side of the profile is provided with an installation groove, the side baffle assembly is connected to the installation groove, and a limiting structure is connected to the lower end of the profile and supports the side baffle assembly upward.

[0014] Compared with the prior art, the oil cup mounting structure of this utility model has the following advantages:

[0015] This utility model's oil cup installation structure features a limiting structure whose functional end can elastically deform under the force of the oil cup hook. This allows the oil cup hook to overcome the resistance of the limiting structure and be inserted into the mounting cavity. After the oil cup hook is installed in the mounting cavity, the functional end of the limiting structure presses against the limiting part, thus securing the oil cup hook entirely within the mounting cavity. This improves the installation stability of the oil cup hook, prevents the oil cup from easily falling off, and enhances the overall structural stability of the range hood. Compared to the integral injection molding of the limiting structure and the range hood body, processing the limiting structure separately before connecting it to the range hood body improves the structural strength and toughness of the limiting structure. Therefore, it avoids the problem of the functional end of the limiting structure easily breaking due to repeated deformation, thereby improving the overall structural stability of the oil cup installation structure.

That is, in some embodiments of this utility model, these practical details are not essential.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art.

[0030] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0031] Please see Figures 2 to 5 This utility model discloses an oil cup installation structure, which includes a range hood body 1, a limiting structure 2, and an oil cup assembly 3. The range hood body 1 has a hanging cavity a, with a downward-facing hanging interface. The limiting structure 2 is connected to the range hood body 1, and its functional end extends into the hanging cavity a. The oil cup assembly 3 includes an oil cup 31 and oil cup hooks 32. Oil cup hooks 32 are provided on both sides of the oil cup 31, and each oil cup hook 32 has a limiting part 321. When the oil cup hook 32 moves from the hanging interface into the hanging cavity a, the limiting part 321 presses against the functional end of the limiting structure 2 in the installation direction, causing the limiting structure 2 to deform and the limiting part 321 to pass through. After the oil cup hook 32 is installed in the hanging cavity a, the functional end of the limiting structure 2 presses against the limiting part 321 in the installation direction.

[0032] In this embodiment, the oil cup 31 is installed at the bottom of the back plate assembly 4 of the range hood body 1. During the exhaust process, the oil and water mixture in the fumes accumulates in the air collection chamber and on the volute of the exhaust fan, eventually flowing into the oil cup 31 for collection. The range hood body 1 has two hanging cavities a, located at opposite ends of the bottom. The length of the oil cup 31 corresponds to the length of the bottom of the range hood body 1, so that the positions of the two oil cup hooks 32 correspond to the positions of the two hanging cavities a. The active end of the limiting structure 2 extends into the hanging cavity a. When subjected to force, the active end of the limiting structure 2 undergoes elastic deformation and applies an elastic reaction force. The fixed end of the oil cup hook 32 is fixedly connected to the oil cup 31. The hook end of the oil cup hook 32 can extend into the hanging cavity a and hang on the preset cavity wall of the hanging cavity a. In this way, the oil cup 31 can be fixedly hung at the bottom of the range hood body 1.

[0033] The active end of the limiting structure 2 faces the hanging interface. The oil cup hook 32 enters the hanging cavity a from the hanging interface. The limiting part 321 is located on the side of the oil cup hook 32 facing the active end of the limiting structure 2. When the oil cup hook 32 enters the hanging cavity a, the limiting part 321 first abuts against the active end of the limiting structure 2. The active end of the limiting structure 2 creates resistance to the movement of the oil cup hook 32 along the installation direction. As the installer applies force to push the oil cup hook 32 into the hanging cavity a, the oil cup hook 32 squeezes the active end of the limiting structure 2, causing it to elastically deform. This allows the oil cup hook 32 to overcome the resistance created by the active end of the limiting structure 2 and thus be installed in place within the hanging cavity a. After the oil cup hook 32 is installed in place, the elastic force generated by the active end of the limiting structure 2 reacts to the limiting part 321, thereby pressing the oil cup hook 32 firmly into the hanging cavity a. This improves the installation stability of the oil cup hook 32, prevents the oil cup 31 from easily falling off, and enhances the overall structural stability of the range hood.

[0034] The limiting structure 2 is separately processed and then connected to the main body 1 of the range hood. Compared with the integral injection molding of the limiting structure 2 and the main body 1 of the range hood, processing the limiting structure 2 separately and then connecting it to the main body 1 of the range hood can improve the structural strength and structural toughness of the limiting structure 2. Therefore, it can avoid the problem that the working end of the limiting structure 2 is prone to breakage due to repeated deformation, thereby improving the overall structural stability of the oil cup installation structure.

[0035] The oil cup mounting structure of this utility model, as follows: Figure 5As shown, the limiting structure 2 includes a connecting part 21 and a deformable part 22. The connecting part 21 is connected to the main body 1 of the range hood, and the cross-section of the functional end of the deformable part 22 is V-shaped or arc-shaped. The connecting part 21 is used to fix the limiting structure 2 on the main body 1 of the range hood. The functional end is located on the deformable part 22, which is used to undergo elastic deformation and generate elastic reaction force when compressed. By making the cross-section of the functional end of the deformable part 22 V-shaped or arc-shaped, the functional end of the deformable part 22 has sufficient space to undergo elastic deformation and generate sufficient elastic force when compressed, thereby improving the clamping effect on the oil cup hook 32.

[0036] The oil cup mounting structure of this utility model, as follows: Figure 5 As shown, a connecting portion 23 is provided between the connecting portion 21 and the deformable portion 22. The connecting portion 23 extends downward from the edge of the connecting portion 21, and the lower edge of the deformable portion 22 is connected to the connecting portion 23. The connecting portion 23 delivers the deformable portion 22 downward, and positions the functional end of the deformable portion 22 on the moving path of the oil cup hook 32 within the hanging cavity a. One end of the connecting portion 23 is connected to the edge of the connecting portion 21, and the other end extends downward at an angle. The deformable portion 22 is connected to the lower end of the connecting portion 23. The connecting portion 23 can shorten the distance between the deformable portion 22 and the hanging interface, so that after the oil cup hook 32 enters the hanging cavity a, the limiting portion 321 can contact and compress the deformable portion 22 earlier, thereby improving the installation effect of the oil cup hook 32.

[0037] The oil cup mounting structure of this utility model, as follows: Figure 5 As shown, the limiting structure 2 is a sheet metal part. The deformation part 22 includes a first deformation segment 221 and a second deformation segment 222. The first deformation segment 221 extends downward from the lower edge of the connecting part 23, and the second deformation segment 222 extends upward from the lower edge of the first deformation segment 221. The first deformation segment 221 and the second deformation segment 222 are connected in an upward-opening V-shape or arc shape. The second deformation segment 222 serves as the functional end of the limiting structure 2, abutting against the limiting part 321 of the oil cup hook 32. When the second deformation segment 222 is squeezed by the limiting part 321, the opening between the first deformation segment 221 and the second deformation segment 222 is compressed, thereby generating an elastic force on the limiting part 321 by the second deformation segment 222. The sheet metal part has higher structural strength and is less likely to break after repeated stress. It is also less likely for the second deformation segment 222 to undergo irreversible plastic deformation, thus ensuring the stability of the limiting structure 2.

[0038] The oil cup mounting structure of this utility model, as follows: Figure 9As shown, the limiting structure 2 is a plastic part. The deformable part 22 extends from the lower edge of the connecting part 23 towards the installation direction of the oil cup hook 32. The lower surface of the deformable part 22 has an arc-shaped protrusion 223 along its width direction, forming the working end. When the protrusion 223 is pressed by the limiting part 321, the deformable part 22 can elastically deform upward together. After the limiting part 321 passes over the protrusion 223, the deformable part 22 returns to its shape downward, and the protrusion 223 is pressed and fixed to the protrusion 223. Plastic parts are lower in cost and easier to process and mold.

[0039] The oil cup mounting structure of this utility model, as follows: Figure 9 As shown, the actuating end has a first surface b and a second surface c arranged opposite to each other. When the oil cup hook 32 is installed into the mounting cavity a, the limiting part 321 presses against the first surface b, and the deforming part 22 deforms, causing the limiting part 321 to pass over the actuating end. After the oil cup hook 32 is installed in place in the mounting cavity a, the second surface c presses against the limiting part 321 in the installation direction. The first surface b and the second surface c are inclined relative to each other. When the oil cup hook 32 just enters the mounting cavity a, the limiting part 321 first presses against the first surface b. The first surface b can decompose the force exerted by the limiting part 321 on the actuating end, thereby generating a component force that makes it easier for the actuating end to undergo elastic deformation, so that the limiting part 321 can more easily overcome the resistance of the actuating end and pass over the actuating end. After the limiting part 321 passes over the actuating end, the second surface c presses against the limiting part 321 to generate a downward mounting direction clamping force on the limiting part 321, thereby further improving the clamping effect of the actuating end on the limiting part 321.

[0040] The oil cup mounting structure of this utility model, as follows: Figure 4 and Figure 9 As shown, a connecting post 111 is also provided inside the hanging cavity a. The limiting structure 2 is connected to the connecting post 111 and located inside the hanging cavity a. In conjunction with the embodiment of the connecting part 21 described above, the connecting part 21 can have a connecting hole, which is fixedly connected to the connecting post 111 to achieve the fixed installation of the limiting structure 2 inside the hanging cavity a. Installing the limiting structure 2 inside the hanging cavity a prevents the limiting structure 2 from being exposed and affecting the appearance of the range hood, thus also providing concealment and protection for the limiting structure 2.

[0041] This utility model also proposes a smoke hood, such as Figure 2 and 6 As shown, the oil cup installation structure described above is adopted. Blocks 11 are connected to the left and right sides of the range hood body 1. The hanging cavity a is located on the block 11, and the lower surface of the block 11 has a hanging interface. The limiting structure 2 is connected to the block 11, and its working end extends into the hanging cavity a. The block 11 is connected to the range hood body 1, and the oil cup hook 32 is hung inside the block 11. Forming the hanging cavity a through the block 11 avoids creating a cavity on the range hood body 1, thus simplifying the formation of the hanging cavity a and improving its structural strength.

[0042] The smoke hood of this utility model, such as Figure 2 and 6 As shown, the system also includes a back panel assembly 4. Profiles 12 are provided on both sides of the main body 1 of the range hood. The back panel assembly 4 is connected between the two profiles 12, and a block 11 is connected to the lower end of the profile 12. The profile 12 is a high-strength structure on the back panel assembly 4 and has sufficient thickness to connect with the block 11, thus improving the connection strength between the block 11 and the back panel assembly 4. It is understandable that during the operation of the range hood, the weight of the oil cup 31 increases after collecting oil, thus increasing the gravity on the block 11. Connecting the block 11 to the profile 12 prevents the back panel assembly 4 from being easily damaged or deformed due to the increased gravity from the oil cup 31, thereby improving the overall structural stability of the back panel assembly 4.

[0043] The smoke hood of this utility model, such as Figure 2 and 6 As shown, the range hood also includes a side baffle assembly 5. The front side of the profile 12 has a mounting groove, and the side baffle assembly 5 is connected to the mounting groove. The limiting structure 2 is connected to the lower end of the profile 12 and supports the side baffle assembly 5 upwards. The rear side of the side baffle assembly 5 is connected to the mounting groove, enabling a fixed connection between the side baffle assembly 5 and the profile 12, thereby fixing the side baffle assembly 5 to the left and right sides of the back panel assembly 4. The rear end of the bottom side of the side baffle assembly 5 overlaps downwards on the limiting structure 2, so the blocking block 11 can provide upward support for the side baffle assembly 5, preventing concentrated force on the rear side of the side baffle assembly 5 and improving the installation stability of the side baffle assembly 5.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
