Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to a range hood that is easy to disassemble and repair. Background Technology

[0002] In daily life, range hoods are an indispensable kitchen appliance, and their installation stability and ease of maintenance directly affect the user experience and safety. Among kitchen appliances, the installation stability of range hoods is directly related to usage safety, but their existing hanging structures have significant support risks. Currently, most range hoods on the market are fixed to the wall via a mounting plate. In specific installation, mounting holes must first be pre-drilled in the wall, then the mounting plate is fixed with expansion bolts, and finally the range hood is hung on the mounting plate.

[0003] Currently, most range hoods on the market use a "single-point mounting" design, meaning the back of the hood is connected to the wall panel via only one hook, with the entire weight of the unit borne by this single connection point. This design reveals significant drawbacks over long-term use: when the range hood is operating, the high-speed fan generates continuous vibration, which repeatedly acts on the connection between the mounting panel and the wall. Because it relies on only one connection point, the vibration energy cannot be dispersed, easily leading to the gradual loosening of the mounting bolts and even wear and expansion of the wall mounting holes. Especially for older units, accumulated grease and grime increase the weight of the unit, further exacerbating the stress on the connection point, causing deformation of the mounting area or hook disengagement, significantly increasing the risk of falling. Furthermore, the existing connection between the mounting panel and the hood is mostly rigid, lacking a cushioning structure. The impact force from vibration is directly transmitted to the wall, potentially causing loosening of the installation structure and accelerating wear on the hood components, shortening the equipment's lifespan. When cleaning or repairing a range hood, disassembly requires loosening the single mounting point. During this process, the hood is prone to wobbling due to imbalance, increasing maintenance difficulty and potentially causing damage to surrounding cabinets or walls. Therefore, to address the issues of poor support stability and easy loosening / falling caused by vibration in existing range hoods with single-point mounting, a structural design that distributes stress, enhances connection reliability, and facilitates disassembly and assembly is urgently needed to improve equipment safety and ease of maintenance. Utility Model Content

[0004] To address the aforementioned issues, a range hood that is easy to disassemble and repair is provided. By setting up a mounting plate and auxiliary brackets, the number of mounting points on the range hood body is increased, thereby improving the connection stability of the range hood body and solving the problem of poor connection stability caused by the single-point mounting of traditional range hoods.

[0005] To address the problems of existing technologies, this utility model provides a range hood that is easy to disassemble and maintain, including a range hood body and a mounting mechanism for mounting the range hood body to a wall. The mounting mechanism includes a mounting plate, a first hook, a second hook, and an auxiliary hook. The mounting plate is connected to the wall by expansion bolts. The first hook and the second hook are fixed to the back of the range hood body. The second hook is located below the first hook. The first hook can be engaged with the mounting plate. One end of the auxiliary hook is connected to the wall by expansion bolts, and the other end of the auxiliary hook is connected to the second hook.

[0006] Preferably, the mounting plate is provided with a slot, the first hook can be inserted into the slot, and a buffer pad is provided on the contact surface between the first hook and the slot.

[0007] Preferably, the mounting plate has first oblong holes at both ends, and the expansion bolts can move vertically within the first oblong holes.

[0008] Preferably, the auxiliary mounting bracket includes a middle plate, a connecting plate, a third hook, and a connector. The middle plate is disposed between the range hood body and the mounting plate. One end of the connecting plate is hinged to the middle plate and the other end is hinged to the third hook. The third hook is connected to the second hook. The connector is snapped onto the top edge of the range hood body.

[0009] Preferably, the upper end of the intermediate plate is provided with a second oblong hole. The connecting member includes an adjusting bolt and an angle steel. One end of the screw of the adjusting bolt is welded to the expansion bolt and the other end passes horizontally through the second oblong hole and the angle steel. The angle steel is located at the top edge of the range hood body. By rotating the nut of the adjusting bolt, the intermediate plate can be pressed tightly against the back of the range hood body.

[0010] Preferably, one side of the intermediate plate contacts the range hood body and the other side contacts the mounting plate, and buffer pads are respectively provided on the surfaces of the intermediate plate that contact the range hood body and the mounting plate.

[0011] Preferably, a cushioning pad is provided on the side of the third hook that contacts the second hook.

[0012] Preferably, the connecting plate is provided with several through holes.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. By setting auxiliary mounting brackets, the number of mounting points for the range hood body is increased, thereby increasing the stability of the range hood body installed on the wall. At the same time, by setting buffer pads on both sides of the middle plate in the auxiliary mounting brackets, the vibration generated by the fan in the range hood body when it is working is prevented from being transmitted to the mounting plate, thus preventing the mounting plate from loosening when it is connected to the wall due to vibration, thereby increasing the stability of the device.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1-6As shown, this utility model provides a range hood that is easy to disassemble and repair, including a range hood body 1 and a mounting mechanism 2 for hanging the range hood body 1 on the wall. The mounting mechanism 2 includes a mounting plate 20, a first hook 21, a second hook 22 and an auxiliary hanging component 23. The mounting plate 20 is connected to the wall by expansion bolts. The first hook 21 and the second hook 22 are fixed to the back of the range hood body 1. The second hook 22 is located below the first hook 21. The first hook 21 can be snapped onto the mounting plate 20. One end of the auxiliary hanging component 23 is connected to the wall by expansion bolts, and the other end of the auxiliary hanging component 23 is connected to the second hook 22.

[0024] When installing the range hood body 1, mark the drilling points at the determined installation location using a tape measure and pencil, and then drill holes. The drilling depth and diameter should be determined according to the specifications of the expansion bolts, generally 6-8 cm deep, with a diameter slightly larger than the expansion bolt diameter. Place the mounting plate 20 into the drilled holes, and insert the upper end of the auxiliary bracket 23 into the expansion bolt holes. Drill holes and install expansion bolts at the top and bottom positions on the wall. Use a level to check if the mounting plate 20 is level. Install a backflow preventer at the flue outlet of the range hood body 1 to prevent backflow of fumes. Seal the backflow preventer and flue interface with sealant to enhance the seal. Connect one end of the exhaust pipe to the exhaust port of the range hood and the other end to the backflow preventer. Ensure a secure connection; tape or hose clamps can be used for fixation. The exhaust pipe should be kept as straight as possible, avoiding excessive bends to reduce exhaust resistance. If the exhaust pipe is too long, it can be trimmed appropriately, but the trimmed length must ensure proper connection and use. Hang the range hood body 1 on the mounting plate 20, ensuring it is securely attached. Locate the pre-installed power outlet in the kitchen and ensure its voltage matches the rated voltage of the range hood body 1. Finally, after connecting the power, turn on all the function buttons on the range hood body 1 to check if the fan is operating normally, if the suction power is sufficient, and if there are any abnormal noises. Simultaneously, check the exhaust pipe for any smoke leaks; if any are found, seal them immediately.

[0025] It should be noted that the mounting plate 20 is first installed in the holes of the expansion bolts, and then the auxiliary hanging part 23 is installed. The second hook 22 is set below the first hook 21, which can make multi-point connections to the range hood body 1 and increase the stability of the connection of the range hood body 1.

[0026] The mounting plate 20 is provided with a slot, and the first hook 21 can be inserted into the slot. A cushioning pad is provided on the contact surface between the first hook 21 and the slot. Figures 4-5As shown, the first hook 21 is a detachable connecting slot. Under the influence of the weight of the range hood body 1, the first hook 21 is tightly connected to the slot. Setting a buffer pad at the connection between the first hook 21 and the slot can reduce the impact of the vibration generated by the fan inside the range hood body 1 on the connection between the range hood body 1 and the mounting mechanism 2.

[0027] The mounting plate 20 has first oblong holes 200 at both ends, allowing the expansion bolts to move vertically within these holes. Figures 4-5 As shown, the first waist-shaped hole 200 can further increase the adaptability of the device. When the mounting plate 20 is not level when it is installed on the wall by expansion bolts, the horizontal installation adjustment of the range hood body 1 can be achieved by adjusting the mounting plate 20 in the vertical direction.

[0028] The auxiliary mounting bracket 23 includes a middle plate 230, a connecting plate 232, a third hook 233, and a connector 234. The middle plate 230 is positioned between the range hood body 1 and the mounting plate 20. One end of the connecting plate is hinged to the middle plate 230, and the other end is hinged to the third hook 233. The third hook 233 is connected to the second hook 22. The connector 234 is snapped onto the top edge of the range hood body 1. Figure 6 As shown, the upper end of the middle plate 230 is connected to the wall, and the range hood body 1 is lifted at a certain point through the third hook 233, making the connection and installation of the range hood body 1 more stable.

[0029] A second oblong hole 231 is vertically provided at the upper end of the middle plate 230. The connecting piece 234 includes an adjusting bolt 2340 and an angle steel 2341. One end of the screw of the adjusting bolt 2340 is welded to the expansion bolt, and the other end horizontally passes through the second oblong hole 231 and the angle steel 2341. The angle steel 2341 is located at the top edge of the range hood body 1. By rotating the nut of the adjusting bolt 2340, the middle plate 230 can be pressed tightly against the back of the range hood body 1. Figures 4-5 As shown, since the screw part of the adjusting bolt 2340 is fixed on the expansion bolt connected to the wall, pulling the upper end of the middle plate 230 upward will make the third hook 233 and the second hook 22 tightly connected. At this time, the position of the screw part of the adjusting bolt 2340 in the second oblong hole 231 can make the middle plate 230 have a lifting effect on the second hook 22. Rotating the nut on the adjusting bolt 2340 can fix the position of the middle plate 230. The angle steel 2341 mainly plays the role of supporting the adjusting bolt 2340, which facilitates the rotation of the nut of the adjusting bolt 2340. When disassembling the range hood body 1, by screwing the nut of the adjusting bolt 2340, the entire range hood body 1 is lifted up, thereby making the first hook 21, the second hook 22 contact the mounting plate 20 and the third hook 233 to realize the disassembly and maintenance of the range hood.

[0030] One side of the intermediate plate 230 contacts the range hood body 1, and the other side contacts the mounting plate 20. Buffer pads are provided on the contact surfaces of the intermediate plate 230 with both the range hood body 1 and the mounting plate 20. To further increase the stability of the device, by providing buffer pads on the contact surfaces of the intermediate plate 230 with the range hood body 1 and the mounting plate 20, the intermediate plate 230 can fill the gap between the range hood body 1 and the mounting plate 20. This also reduces the transmission of vibrations generated by the range hood body 1 during operation to the mounting plate 20, preventing the mounting plate 20 from loosening due to vibrations. Similarly, a buffer pad is provided on the side of the third hook 233 that contacts the second hook 22. This also significantly reduces the risk of loosening due to vibration.

[0031] To further increase the stability of the device connection, several through holes are provided on the connecting plate 232 to reduce the self-weight of the structure and reduce the load on the expansion bolts and the wall.

[0032] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
