Description

Technical Field

[0001] This utility model relates to a mounting structure, and more particularly to a mounting structure for a range hood and a range hood. Background Technology

[0002] Ceiling-mounted range hoods are gaining popularity due to their fan system being installed inside the ceiling, resulting in lower noise levels and the ability to miniaturize the air intake components below the hood. Currently, the installation structure of ceiling-mounted fan modules typically involves directly mounting them to the ceiling using expansion screws.

[0003] For example, a range hood disclosed in Chinese utility model patent application number 202221537556.0 includes an air intake component, a power device for installation in the ceiling, and a connecting pipe installed between the air intake component and the power device.

[0004] The direct ceiling mounting method requires a longer time for installers to lift the fan module, and the operation is relatively cumbersome. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a mounting structure that addresses the shortcomings of the existing technology and solves the problem of long lifting time of the fan system during installation.

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

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a mounting structure for a range hood, including a first bracket and a second bracket, both connected to an external mounting base. The first bracket and the second bracket are spaced apart in the left-right direction and both extend in the front-back direction. The characteristic is that two extensions are provided on the side of the first bracket and the second bracket that are close to each other. The extensions on each bracket extend towards the other bracket, and the extensions on each bracket are spaced apart along the length direction of their respective brackets. The upper surface of the extension is lower than the upper surface of the corresponding bracket. The mounting structure also includes hooks connected to the range hood. The number of hooks corresponds to the number of extensions, and each hook can be hung on the corresponding extension to achieve pre-installation.

[0008] By providing extensions for hook attachment on the first and second brackets, the problem of long lifting time for the fan system during installation is solved.

[0009] To provide shock absorption, a first shock-absorbing pad is provided on the extension, and the hook is hung on the first shock-absorbing pad.

[0010] In order to fix the first shock-absorbing pad on the extension, a positioning post extending downward is formed at the bottom of the first shock-absorbing pad, a positioning hole is provided on the extension for the positioning post to pass through, and a limiting part is provided on the positioning post to limit it to the side of the extension away from the first shock-absorbing pad.

[0011] Furthermore, the extension and the hook are connected by screws, which pass through from bottom to top. The extension has a slotted hole extending in the front-to-back direction to facilitate screw adjustment. Through the slotted hole on the mounting structure, if the front-to-back position of the range hood's air intake assembly and the fan system does not match after the user has installed the base tiles in the later stages of renovation, the screws can be slightly loosened, the fan system moved back and forth appropriately, and the screws tightened again after alignment. This solves the problem of inaccurate front-to-back position matching between the fan system and the air intake assembly in the later stages of installation.

[0012] To provide shock absorption, a second shock-absorbing pad is provided between the screw and the bottom of the extension.

[0013] To prevent the fan system from sliding due to fan vibration after its position is fixed, the part of the extension located around the waist-shaped hole is provided with anti-slip teeth, and the second shock-absorbing pad abuts against the anti-slip teeth.

[0014] To facilitate screw adjustment, the first damping pad has a flange extending toward the inside of the waist-shaped hole, and the inside of the flange has a clearance hole to facilitate screw adjustment.

[0015] In order for the second shock-absorbing pad to effectively contact the anti-slip teeth, the bottom of the anti-slip teeth is lower than the bottom of the flange.

[0016] In order to enable the extensions on the first and second brackets to be directly adapted to the hook positions on the wind turbine system, so that the distance between the first and second brackets does not need to be adjusted during installation, the mounting structure also includes a third bracket for connecting the first and second brackets.

[0017] In order to connect the range hood and the extension, the hook includes a connecting part that connects to the range hood and a hanging part that can be hung on the extension.

[0018] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a range hood that uses the aforementioned hanging structure.

[0019] Compared with the prior art, the advantages of this utility model are as follows: by setting extensions for hook attachment on the first and second brackets, the problem of long lifting time of the fan system during installation is solved; through the waist-shaped holes on the mounting structure, if the front and rear positions of the range hood's air intake component and the fan system do not match after the user has laid the bottom tiles in the later stage of decoration, the screws can be slightly loosened, the fan system can be moved back and forth appropriately, and after matching, the screws can be tightened again, thus solving the problem of inaccurate front and rear position matching between the fan system and the air intake component in the later stage of installation.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] 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.

[0028] See Figures 1-2 A range hood includes a fan system 21 and an air inlet assembly 22 disposed below the fan system 21. The fan system 21 is connected to an external mounting base via a mounting structure. In this embodiment, the external mounting base is a ceiling.

[0029] The mounting structure includes a first bracket 11 and a second bracket 12, both of which are connected to an external mounting base. The first bracket 11 and the second bracket 12 are spaced apart in the left-right direction. Both the first bracket 11 and the second bracket 12 extend in the front-back direction. The first bracket 11 has a first mounting hole 111, and the second bracket 12 has a second mounting hole 121. The first bracket 11 and the second bracket 12 can be fixed to the ceiling using expansion screws at the mounting holes. Each mounting hole is located near the front and rear ends of the corresponding bracket.

[0030] Two extensions 13 are provided on the side of the first bracket 11 and the second bracket 12 that are close to each other. The extensions 13 on each bracket extend toward the other bracket, and the extensions 13 on each bracket are spaced apart along the length of their respective brackets. The upper surfaces of the first bracket 11 and the second bracket 12 are fixed to the ceiling, while the upper surfaces of the extensions 13 are lower than the upper surfaces of the corresponding brackets, i.e., there is a certain gap between them and the ceiling.

[0031] The mounting structure also includes hooks 14 connected to the fan system 21. The number of hooks 14 corresponds to the extension 13. In this embodiment, there are four hooks 14, with two hooks 14 on each of the left and right sides of the fan system 21, and the hooks 14 on each side are spaced apart in the front-back direction. Each hook 14 includes a connecting part 141 connected to the fan system 21 and a hanging part 142 that can be hung on the extension 13. The hanging part 142 of each hook 14 can be hung on the corresponding extension 13 to achieve the pre-installation of the range hood. At this time, the hooks 14 are only supported on the extension 13 and are not fixed to each other, but after the pre-installation is completed, the fan system 21 does not need to be lifted for the next fixing operation.

[0032] See Figures 1-3 The first bracket 11 and the second bracket 12 are connected by a horizontally arranged third bracket 18. The third bracket 18 can be connected to the first bracket 11 and the second bracket 12 by screws. By setting the third bracket 18, the extensions on the first bracket 11 and the second bracket 12 can be directly adapted to the hook positions on the fan system 21, thus eliminating the need to adjust the spacing between the first bracket 11 and the second bracket 12. The third bracket 18 has a downwardly recessed profile 181 in the middle, which facilitates alignment with the center line of the range hood space and facilitates installation.

[0033] See Figures 3-5 A first shock-absorbing pad 15 is provided on the extension 13, and the hanging part 142 of the hook 14 is hung on the first shock-absorbing pad 15. A positioning post 151 extending downward is formed at the bottom of the first shock-absorbing pad 15, and a positioning hole 131 is provided on the extension 13 for the positioning post 151 to pass through. A limiting part 1511 is provided on the positioning post 151 that can limit the extension 13 to the side away from the first shock-absorbing pad 15.

[0034] During installation, when lifting the fan system 21, the hook 14 can be placed above the first shock-absorbing pad 15 from front to back, and then you can let go. At this time, the fan system 21 can be hung on the first shock-absorbing pad 15, which solves the problem of the long lifting time of the fan system 21 during installation.

[0035] The extension 13 and the hook 14 are connected by a screw 16, which passes through from bottom to top. The extension 13 has a waist-shaped hole 132 extending in the front-back direction to facilitate adjustment of the screw 16's position. The first shock-absorbing pad 15 has a flange 152 extending inward toward the waist-shaped hole 132, and an clearance hole 153 is formed on the inner side of the flange 152 to facilitate adjustment of the screw 16's position. Preferably, the front-back dimension of the waist-shaped hole 132 can accommodate a 10mm front-back movement of the screw 16.

[0036] A second shock-absorbing pad 17 is provided between the screw 16 and the bottom of the extension 13. Anti-slip teeth 133 are provided on the portion of the extension 13 located around the waist-shaped hole 132, and the second shock-absorbing pad 17 abuts against the anti-slip teeth 133. The anti-slip teeth 133 are designed to prevent slippage due to fan vibration after the fan system 21 is finally fixed in its final position.

[0037] See Figures 4-5 To ensure effective contact between the second damping pad 17 and the anti-slip teeth 133, the bottom of the anti-slip teeth 133 is lower than the bottom of the flange 152. The gap between each anti-slip tooth 133 is set such that when the screw 16 with the second damping pad 17 is in any position, the number of effective anti-slip teeth 133 covered by the second damping pad 17 on one side must be at least two to ensure the anti-slip effect.

[0038] By using the structure of the waist-shaped hole 132 and screw 16 on the mounting structure, if the front and back positions of the range hood's air intake component 22 and the fan system 21 do not match after the user has laid the bottom tiles in the later stage of the renovation, the screw 16 can be slightly loosened, the fan system 21 can be moved back and forth appropriately, and after matching, the screw 16 can be tightened again. This solves the problem of inaccurate front and back position matching between the fan system 21 and the air intake component 22 in the later stage of installation.

[0039] The mounting structure in this embodiment is relatively thin and does not occupy much of the limited ceiling space, allowing for trial installation in different ceiling height environments.
