Description

Technical Field

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

[0002] With the increasing proportion of kitchen wall cabinets installed, repairs become more complicated in scenarios where the range hood installation includes side cabinets on both sides. These side cabinets often obstruct the top screw positions, preventing screwdrivers from reaching in and hindering repairs. For this situation, the first solution is to remove the entire range hood from its mounting position. This is difficult and can easily soil the area below the range hood, posing a greater risk if it falls. Furthermore, it requires detaching the exhaust pipe from the hood, which allows grease to drip out and makes reinstallation more prone to leaks due to the grease buildup. The second solution involves a lifting mechanism, allowing the range hood to be lowered for repairs. However, this requires a lifting function, which is not only more expensive but also makes it impossible to lower the hood for repairs if the lifting function fails. The third solution uses a lifting hook to adjust the gap between the range hood and the cabinet. However, the lifting hook needs to be adjusted synchronously from left to right. Because the range hood is relatively heavy, it is easy for the left and right sides to become out of sync and get stuck. In conclusion, further improvements are needed to the existing range hood repair structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a maintenance structure for a range hood that is simple in structure, easy to use, and reliable, in light of the above-mentioned existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a maintenance structure for a range hood, including a fan frame and a fixed frame provided on the back of the fan frame, the fixed frame is provided with a hook, and the upper part of the back plate of the fan frame is provided with a hooking hole for hanging on the hook, characterized in that: it also includes a fan frame height adjustment mechanism, which can adjust the relative height between the fan frame and the fixed frame when the hooking hole is detached from the hook.

[0005] As a preferred embodiment, the wind turbine frame height adjustment mechanism includes an adapter hook that protrudes upward from the upper edge of the back plate of the wind turbine frame.

[0006] To minimize the size of the adapter hook while meeting the minimum maintenance height requirement, an exhaust hood is installed on the top of the fan frame, and the top of the adapter hook is lower than the top of the exhaust hood.

[0007] The adapter hook can have various installation structures. Preferably, a reinforcing bracket is fixed to the outer periphery of the hook hole, the adapter hook is fixed on the reinforcing bracket, and the adapter hook corresponds one-to-one with the hook hole and is located directly above the hook hole.

[0008] As another preferred embodiment, the wind turbine frame height adjustment mechanism includes an adapter plate protruding upward from the upper edge of the back plate of the wind turbine frame, and the adapter plate has an adapter hanging hole.

[0009] Further preferably, the adapter plate and the back plate of the fan frame are integrally formed, or the adapter plate and the back plate of the fan frame are separate parts. This design eliminates the need for adapter hooks, making it more convenient to use, but it results in relatively more material waste and higher costs.

[0010] As another preferred embodiment, the height adjustment mechanism of the wind turbine frame is an elastic element, with the upper end of the elastic element fixed to the fixed frame and the lower end of the elastic element fixed to the wind turbine frame.

[0011] The lower end of the elastic element can be fixed to different parts of the wind turbine frame. Preferably, the lower end of the elastic element is fixed to the upper part of the back plate of the wind turbine frame or to the top plate of the wind turbine frame.

[0012] The elastic element can have various structures; preferably, the elastic element is a steel wire or a spring.

[0013] As another preferred embodiment, the wind turbine frame height adjustment mechanism includes a motor and a rope. The motor is mounted on the top plate of the wind turbine frame, one end of the rope is attached to the drive output end of the motor, and the other end of the rope is attached to the fixed frame. This configuration allows the rope to automatically retract or extend under the drive of the motor, making maintenance more convenient.

[0014] Compared with the prior art, the advantages of this utility model are as follows: The maintenance structure of this range hood has a fan frame height adjustment mechanism. When the mounting hole is detached from the hook, the fan frame height adjustment mechanism can adjust the relative height between the fan frame and the fixed frame. When the range hood needs to be maintained, the range hood can be lowered to a certain position through the fan frame height adjustment mechanism, so that there is enough maintenance height between the top of the lower box of the range hood and the side cabinet of the kitchen wall cabinet, ensuring that the screwdriver can be inserted for disassembly and maintenance. The structure is very simple and maintenance is very convenient. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, the maintenance structure of the range hood in this embodiment includes a fan frame 1 and a fixing frame 2 located on the back of the fan frame 1. The fixing frame 2 is provided with a hook 21. The upper part of the back plate 11 of the fan frame 1 is provided with a hanging hole 13 for hanging on the hook 21. When the hanging hole 13 is detached from the hook 21, the height adjustment mechanism of the fan frame can adjust the relative height between the fan frame 1 and the fixing frame 2.

[0024] The fan frame height adjustment mechanism of this embodiment includes an adapter hook 3 protruding upward from the upper edge of the back plate 11 of the fan frame 1. The adapter hook 3 has an adapter hanging hole 31 that mates with the hook 21. To improve the installation firmness of the adapter hook 3, a reinforcing bracket 5 is fixed to the outer periphery of the hanging hole 13, and the adapter hook 3 is fixed to the reinforcing bracket 5. The adapter hanging hole 31 corresponds one-to-one with the hanging hole 13 and is located directly above the hanging hole 13. In this embodiment, there are two hanging holes 13, which are spaced apart from each other on the left and right. Correspondingly, there are also two adapter hanging holes 31, which are spaced apart from each other on the left and right. An air outlet hood 4 is installed on the top of the fan frame 1. The top of the adapter hook 3 is lower than the top of the air outlet hood 4. In this way, the size of the adapter hook 3 is minimized while meeting the minimum maintenance height requirement.

[0025] Alternatively, the wind turbine frame height adjustment mechanism can also use an adapter plate (not shown in the figure). The adapter plate can be integrally formed with the back plate 11 of the wind turbine frame 1, or it can be a separate component from the back plate 11 of the wind turbine frame 1. The adapter plate protrudes upward from the upper edge of the back plate 11 of the wind turbine frame 1, and has adapter hanging holes. This maintenance structure eliminates the need for adapter hooks, making it more convenient to use, but it is relatively wasteful of materials and has a relatively high cost.

[0026] When maintenance is required, first lift the range hood down so that hook 21 is detached from the mounting hole 13. Then, hang the range hood's adapter mounting hole 31 onto hook 21. At this time, if... Figure 4 As shown, the entire range hood moves downwards, leaving a maintenance gap 10 between the lower housing 8 and the side cabinet 9, ensuring that a screwdriver can be inserted for disassembly and maintenance.

[0027] Example 2:

[0028] like Figure 5 As shown, the height adjustment mechanism of the fan frame in this embodiment is an elastic element 6. The upper end of the elastic element 6 is fixed to the fixed frame 2, and the lower end of the elastic element 6 is fixed to the back plate 11 or the top plate 12 of the fan frame 1. The elastic element in this embodiment is made of spring steel wire, with the upper end of the spring steel wire fixed to the fixed frame 2 and the lower end fixed to the top plate 12 of the fan frame 1.

[0029] When maintenance is needed, first lift the range hood down so that the hook 21 is disengaged from the mounting hole 13. Then, use the spring steel wire to pull the range hood down, leaving a maintenance gap. At this time, even if the maintenance technician lets go, the range hood will not fall down, which is relatively safe.

[0030] Example 3:

[0031] like Figure 6 As shown, the fan frame height adjustment mechanism of this embodiment includes a motor 71 and a rope 72. The motor 71 is mounted on the top plate 12 of the fan frame 1. The rope 72 is preferably a steel wire rope with a spring structure. One end of the rope 72 is mounted on the drive output end of the motor 71, and the other end of the rope 72 is mounted on the fixed frame 2. This makes it easier to lift the range hood during maintenance.

[0032] When maintenance is needed, first lift the range hood down so that the hook 21 is disengaged from the mounting hole 13. Then, driven by the motor 71, the rope 72 extends, causing the range hood to descend and creating a maintenance gap. Similarly, even if the maintenance technician lets go, the range hood will not fall, making it relatively safe.
