Description

Technical Field

[0001] This utility model relates to the field of controller bracket technology, specifically a small and lightweight controller bracket structure. Background Technology

[0002] A range hood controller bracket is a metal or plastic structural component used to fix and support the control panel and electronic components of a range hood. It is usually installed on the range hood panel or in a wall cabinet. In order to control the range hood, mechanical buttons or touch screens are set on the panel of the bracket. It must also be resistant to high temperature, oil stains and mechanical stability to ensure that the controller operates reliably in the kitchen environment for a long time.

[0003] Nowadays, most controller buttons or touch screens are located directly outside the range hood for users to control. However, being directly outside the range hood means that the panel is exposed to an oily environment for a long time. After a long period of time, the oil and other debris on the panel will be difficult to clean, which may cause the touch or buttons to malfunction. There is also a risk that the panel may be accidentally touched by the user when they are moving items in the kitchen, which may cause damage to the panel.

[0004] The front panel of the range hood has a large space, so when installing the controller bracket, it is fixed directly on the entire front panel. When the controller needs to be replaced, the entire front panel needs to be removed. Because the front panel is large and heavy, the disassembly process is also quite difficult. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a small and lightweight controller support structure, which has the advantage of protecting the controller from damage and oil contamination.

[0006] To achieve the aforementioned goal of higher installation stability, this utility model provides the following technical solution: it includes a range hood body, a controller bracket, and a main bracket, wherein the controller bracket is disposed on the front side of the range hood body, and the main bracket is disposed on the rear side of the range hood body; The controller bracket includes a protective plate, a controller support plate, and a rotating shaft. The rotating shaft is rotatably connected to the range hood body. There are two rotating shafts, which are arranged symmetrically. The protective plate is fixedly connected between the two rotating shafts. The two sides of the controller support plate are rotatably connected to the rotating shaft. The main support includes a suspension groove and a support base plate that fit together, and a shock-absorbing oil cavity is also provided in the suspension groove.

[0007] Preferably, the shock-absorbing oil chamber includes a first oil chamber and a second oil chamber, which are interconnected. There are two hanging grooves located on the rear side of the range hood body and arranged symmetrically. A protective cavity is opened in the middle of the front side of the range hood body, and a rotating shaft cavity is connected to the protective cavity. The controller bracket is located in the protective cavity.

[0008] Preferably, a synchronous extrusion block is movably arranged inside the first oil cavity, and a pressure adjusting screw is internally threaded to the synchronous extrusion block. The pressure adjusting screw is rotatably connected to the range hood body. The second oil cavity is connected to the suspension groove and the outside. Two buffer blocks are provided in each second oil cavity to seal the connection between the second oil cavity and the suspension groove and the outside.

[0009] Preferably, the rotating shaft is located within the rotating shaft cavity, and there is damping between the two.

[0010] Preferably, the protective plate is rotatably connected to the controller support plate, and rotating pins are fixed on both sides of the controller support plate. The rotating pins are located inside the rotating shaft and are rotatably connected to it. Limiting blocks are also fixed on the outer periphery of the rotating pins. A limiting groove is provided at one end of the rotating shaft near the rotating pin, and the limiting block is located in the limiting groove.

[0011] Preferably, the arc angle of the limiting groove is 90°-180°.

[0012] Preferably, two symmetrical bracket hooks are fixed at one end of the bracket base plate. The bracket hooks are L-shaped and cooperate with the suspension groove.

[0013] Preferably, two front baffles are fixed on the front side of the range hood body. The front baffles are located on both sides of the protective plate and their length is the same as that of the protective plate. A smoke outlet is fixed on the top of the range hood body.

[0014] Compared with the prior art, the present invention provides a small and lightweight controller bracket structure, which has the following advantages: 1. This small and lightweight controller bracket structure allows the controller to be hidden inside the chamber when not in use, preventing external dust and dirt from adhering to the controller support plate or being damaged by accidental contact with external objects. When in use, the controller support plate can be brought out through the protective plate for controlling the on / off switch and other parameters of the range hood. At this time, the protective plate can also be used in conjunction with the front baffle to block oil fumes and prevent them from contacting the surface of the controller support plate and causing pollution to the controller screen.

[0015] 2. This small and lightweight controller bracket structure has a smaller overall size, and all the control components of the range hood are integrated into the controller support plate and protected within a protective cavity. Compared to the current control components where the touch screen is directly set on the front end of the range hood, this control panel is more compact and does not occupy the entire front end of the range hood. It not only does not affect normal use, but also protects the entire panel from direct contact with the outside world. Especially during the replacement process, there is no need to replace the entire front panel; only the controller support plate needs to be replaced. The controller support plate is lightweight, making replacement more convenient.

[0016] 3. The small and lightweight controller bracket structure can also transmit the vibration of the range hood fan to the compressible medium through the setting of the shock-absorbing oil chamber and buffer block. This causes the buffer block to make a small displacement, which is then absorbed and will not be transmitted to the main bracket, thereby preventing the bolts fixing the bracket and the wall from falling off due to long-term vibration.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-9 As shown, the range hood includes a range hood body 10, a controller bracket, and a main bracket. The controller bracket is located on the front side of the range hood body 10 and is equipped with various control components such as circuit boards. Various parameters of the oil press are controlled via a touch screen. The main bracket is located on the rear side of the range hood body 10 and is mounted on the wall to fix the entire range hood. Two front baffles 101 are also fixed on the front side of the range hood body 10 to block the oil fumes. The front baffles 101 are located on both sides of the protective plate 20, and their length is the same as that of the protective plate 20. The front baffles 101 can completely block the front end of the oil press, so that the oil fumes that cannot be sucked into the range hood body 10 are blocked at the front baffles 101. A smoke outlet 102 is fixed on the top of the range hood body 10, through which the oil fumes are discharged to the outside.

[0021] The controller bracket includes a protective plate 20, a controller support plate 21, and a rotating shaft 22. The rotating shaft 22 is rotatably connected inside the range hood body 10. There are two rotating shafts 22, which are symmetrically arranged. The protective plate 20 is fixedly connected between the two rotating shafts 22. The two sides of the controller support plate 21 are rotatably connected to the rotating shafts 22. The main bracket includes a hanging groove 15 and a bracket base plate 30 that cooperate with each other. The hanging groove 15 is also provided with a shock-absorbing oil cavity. Two symmetrical bracket hooks 301 are fixed at one end of the bracket base plate 30. The bracket hooks 301 are L-shaped and cooperate with the hanging groove 15.

[0022] The shock-absorbing oil chamber includes a first oil chamber 13 and a second oil chamber 14, which are interconnected. Two hanging grooves 15 are provided, located symmetrically on the rear side of the range hood body 10, for hanging on the main support. A protective cavity 16 is provided in the middle of the front side of the range hood body 10, and a rotating shaft cavity 11 is connected to the protective cavity 16. The controller bracket is located inside the protective cavity 16. A synchronous extrusion block 131 is movably installed inside the first oil chamber 13, and a pressure adjusting screw 12 is threadedly connected to the synchronous extrusion block 131. The pressure adjusting screw 12 is rotatably connected to the range hood body 10. During production, the shock-absorbing oil chamber is filled with a high-density medium, such as hydraulic oil or water, or a low-density medium, such as air or high-pressure gas such as carbon dioxide. The second oil chamber 14 is connected to the hanging groove 15 and the outside. Each second oil chamber 14 is provided with two buffer blocks 141 for sealing the second oil chamber 14. At the connection point between the suspension groove 15 and the outside, a limit switch is provided on the buffer block 141 to prevent the buffer block 141 from detaching from the second oil chamber 14. Since the hydraulic oil has low compressibility, adjusting the pressure adjusting screw 12 causes the synchronous extrusion block 131 to extrude the hydraulic oil, allowing the buffer block 141 to directly abut against the main support of the range hood. This does not provide shock absorption for the support, but it can make the range hood installation more stable. At this time, the vibration generated by the range hood acts directly on the main support, so the range hood will not shake. The high-pressure gas has high compressibility, so after the compressed gas moves the second oil chamber 14 to both sides, it abuts against the range hood. The high-pressure gas gives the buffer block 141 a certain degree of elasticity. After the range hood is started, the vibration generated by the fan will be absorbed by the high-pressure gas in the second oil chamber 14, which will have a certain shock absorption effect. At this time, the range hood will shake slightly. Users can choose according to their needs.

[0023] The rotating shaft 22 is located inside the rotating shaft cavity 11, and there is damping between the two, that is, external force cannot easily drive the rotating shaft 22 to rotate, and a certain force needs to be applied.

[0024] The protective plate 20 is rotatably connected to the controller support plate 21. Rotating pins 211 are fixed on both sides of the controller support plate 21. The rotating pins 211 are located within and rotatably connected to the rotating shaft 22. Limiting blocks 2111 are also fixed to the outer periphery of the rotating pins 211. A limiting groove 221 is formed at one end of the rotating shaft 22 near the rotating pins 211, and the limiting block 2111 is located within the limiting groove 221. The arc angle of the limiting groove 221 is 90°-100°. When the range hood is not in use, the controller support plate 21 can be moved into the protective cavity 16 by rotating the protective plate 20, thus preventing dust and grease from adhering to the controller support plate. On 21, after using the range hood, the protective plate 20 can be rotated to bring out the controller support plate 21 until the controller support plate 21 is aligned with the front plane of the range hood body 10 and the protective plate 20 is aligned with the front baffle 101. At this time, the protective plate 20 and the front baffle 101 can prevent the oil fumes from continuing to drift out of the range hood body 10. The protection plate 20 can prevent some oil stains from remaining on the controller support plate 21 when the oil fumes drift out from the front face of the range hood body 10. After long-term use, these oil stains accumulate and are difficult to clean, resulting in poor contact of the touch screen of the controller support plate 21 and inability to accurately control the range hood.

[0025] By setting the limiting groove 221, the protection plate 20 is rotated 180°, which in turn drives the controller support plate 21 to rotate 90°. This allows the protection plate 20 to work with the front baffle 101 to block the range hood from the front, preventing oil fumes from passing through the range hood's controller and contaminating the controller screen.

[0026] The cooperation between the protection plate 20 and the controller support plate 21 integrates the control components of the range hood onto the controller support plate 21 and protects them within the protection cavity 16. Compared to the current practice of directly placing the touch screen of the control components on the front end face of the range hood, the control components are more compact and do not occupy the entire front end face of the range hood. Especially during the replacement process, it is not necessary to replace the entire front panel; only the controller support plate 21 needs to be replaced. The controller support plate 21 is also lighter overall, making replacement more convenient.

[0027] Working principle: In use, first fix the bracket base plate 30 to the wall, then install the range hood onto the bracket base plate 30. When the range hood needs to be turned on, the user manually pulls down the protective plate 20. At this time, the protective plate 20 drives the rotating shaft 22 to rotate, causing the limiting block 2111 to move relative to the limiting groove 221. Initially, the limiting block 2111 abuts against one side of the limiting groove 221. When the protective plate 20 and the controller support plate 21 are on the same plane, that is, after the protective plate 20 has rotated 90°, the other side wall of the limiting groove 221 abuts against the limiting plate 221. On the position block 2111, and then continue to rotate the protection plate 20, the controller support plate 21 will rotate upward through the limit block 2111 and the rotating pin 211, and the protection plate 20 will rotate downward. Then the protection plate 20 will continue to rotate 90 degrees, and the controller support plate 21 will also rotate 90 degrees synchronously. At this time, the protection plate 20 and the front baffle 101 are in the same position, the controller support plate 21 is parallel to the front end face of the range hood body 10, and the protection plate 20 and the controller support plate 21 are at 180 degrees. At this time, the range hood can be controlled by the touch screen on the controller support plate 21 to control the switch and various parameters of the range hood.

[0028] When the shock absorption effect of the main bracket needs to be adjusted, the synchronous extrusion block 131 can be moved closer to the protective plate 20 by rotating the pressure adjusting screw 12. This causes the other chamber of the synchronous extrusion block 131 to be extruded, and the medium in this chamber will enter the second oil chamber 14. This causes the two buffer blocks 141 to slide to both sides and gradually abut against the bracket base plate 30 and the bracket hook 301, so that they completely fill the installation gap between the main bracket and the range hood body 10. This prevents the range hood body 10 from shaking significantly due to the vibration of the fan when it is started, and keeps the range hood firmly fixed on the main bracket, so that the range hood cannot be removed at will. At this time, the effect of the range hood abutting and fixing is increased, and the shock absorption effect is reduced. When disassembly is required, 12 needs to be rotated in the opposite direction to loosen 14 and make it detach from the bracket base plate 30 and the bracket hook 301, so that the range hood can be safely removed.

[0029] If the damping oil cavity is filled with a low-density medium, its high compressibility gives it the properties of an elastic pad. Furthermore, when the range hood body 10 is installed on the bracket base plate 30, since the weight of the upper part of the range hood body 10 is much greater than the weight of the lower part, most of the force on the range hood body 10 is borne by the side of the bracket hook 301. The bottom of the bracket hook 301 provides support and experiences less force. Therefore, most of the vibration generated by the range hood body 10 acts on the side of the bracket hook 301. Thus, the medium in the second oil cavity 14 can lift the buffer block 141. By abutting the side of the buffer block 141 against the side of the bracket hook 301 and the side of the bracket base plate 30, the vibration of the range hood fan can be transmitted to the compressible medium through the buffer block 141, causing the buffer block 141 to produce a slight displacement, which is then absorbed and will not be transmitted to the main bracket. This prevents the bolts fixing the bracket and the wall from coming loose due to long-term vibration. At this time, the buffer block 141 can also be abutted against the main bracket. However, since the buffer block 141 has a certain degree of elasticity, its abutting and fixing effect is reduced, while the shock absorption effect is increased.

[0030] When the range hood is turned off, the range hood body 10 can be turned off by controlling the controller support plate 21. Then, the protective plate 20 is rotated upwards in the opposite direction, which drives the rotating shaft 22 to rotate synchronously. At this time, the rotating shaft 22 rotates in the opposite direction, causing the side of the limiting groove 221 that is not abutted to rotate closer to the limiting block 2111 until the side wall of the limiting groove 221 that is not abutted to abuts against the limiting block 2111. At this time, the protective plate 20 and the controller support plate 21 are set at 90°. Continue to rotate the protective plate 20, and the controller support plate 21 will be driven by the limiting block 2111 to rotate synchronously into the protective cavity 16 until the protective plate 20 completely closes the opening of the protective cavity 16. At this time, the controller support plate 21 is sealed and protected inside the protective cavity 16, preventing external dust and dirt from sticking to the controller support plate 21 or being damaged by external objects.

[0031] In summary, this small and lightweight controller bracket structure, through the setting of the controller bracket, allows the controller to be hidden in the cavity when not in use, preventing external dust and dirt from adhering to the controller support plate 21 or being damaged by accidental contact with external objects. When in use, the controller support plate 21 can be brought out through the protective plate 20 for controlling the on / off switch and other parameters of the range hood 10. Moreover, the protective plate 20 can also cooperate with the front baffle 101 to block oil fumes, preventing oil fumes from contacting the surface of the controller support plate 21 and causing pollution to the controller screen. This controller bracket has a small overall size, and the control components of the range hood are all integrated on the controller support plate 21 and protected within the protective cavity 16. Compared with current control components, this design is significantly more efficient. The touchscreen is directly mounted on the front end of the range hood. This control panel is more compact and does not occupy the entire front end of the range hood. It not only does not affect normal use, but also protects the entire panel from direct contact with the outside world. Especially during the replacement process, there is no need to replace the entire front panel; only the controller support plate 21 needs to be replaced. The controller support plate 21 is lightweight, making replacement easier. Furthermore, through the setting of the shock-absorbing oil chamber and the buffer block 141, the vibration of the range hood fan is transmitted to the compressible medium through the buffer block 141, causing the buffer block 141 to produce a slight displacement, which is then absorbed and not transmitted to the main support. This prevents the bolts fixing the support and the wall from falling off due to prolonged vibration.
