[0020] Figure 3 This is a structural schematic diagram of the disassembly of an embodiment of the switch assembly of this application. Detailed Implementation
[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0022] Combination Figure 1 This application provides a range hood 1. The core component of the range hood 1 is a smoke collection assembly 10, which has a main air inlet 101 on its front side. The main air inlet 101 is correspondingly arranged with the stove and can effectively absorb the oil fumes generated during cooking. The range hood 1 includes a volute (not shown) and a centrifugal impeller (not shown), with the centrifugal impeller disposed inside the volute. In some embodiments, the volute and the centrifugal impeller can be installed inside the smoke collection assembly 10. The volute and the centrifugal impeller can work together to generate negative pressure, thereby driving gas convection and discharging the oil fumes from the main air inlet 101 to the air outlet 102. Optionally, the air outlet 102 can be equipped with an exhaust hood or a check valve, and then connected to the flue through a corrugated pipe or other pipe to ensure smooth exhaust of oil fumes.
[0023] In other embodiments, the design structure of the smoke hood 1 includes a frame (not shown) and a smoke collection assembly 10. The smoke collection assembly 10 is mounted on the frame and securely connected to it. The smoke hood 1 can be fixed to a wall via the frame or the smoke collection assembly 10, thus achieving a stable installation. The frame is correspondingly positioned with the air outlet 102 on the smoke collection assembly 10, allowing the gas inside the smoke collection assembly 10 to flow smoothly into the frame from the air outlet 102. The frame is also equipped with a smoke exhaust port, which can be equipped with an exhaust hood or a check valve as needed, and connected to an external flue via a corrugated pipe or other pipe to ensure smooth exhaust of fumes. The frame includes an outer shell, a volute, and a centrifugal impeller housed within the frame. The volute can communicate with the interior of the smoke collection assembly 10. When the centrifugal impeller rotates, it generates negative pressure, thereby driving the gas inside the smoke collection assembly 10 to the exhaust port for discharge. The front side of the smoke collection assembly 10 is provided with a main air inlet 101, which is corresponding to the stove. The main air inlet 101 can draw in the oil fumes generated during cooking, and then discharge them through the air outlet 102 after passing through the smoke collection assembly 10 and the frame.
[0024] Combination Figure 2 In some embodiments, the range hood 1 is further optimized to improve user experience and maintainability. Specifically, the range hood 1 also includes a switch assembly 20 for controlling the operating status of the range hood 1. The smoke collection assembly 10 includes a housing 11 with a mounting port 111 facing the front of the range hood 1. The switch assembly 20 is installed inside the housing 11. The operating surface of the switch assembly 20 is exposed to the front of the range hood 1 through the mounting port 111 for user operation. By providing the mounting port 111 on the housing 11, the switch assembly 20 can directly mate with the housing 11 without complex bonding or other fixing operations with larger plates. This design simplifies the installation process of the switch assembly 20, reduces installation steps and time, and also reduces the risk of failure due to improper installation. When repairing or replacing the switch assembly 20, it can be directly disassembled and installed through the mounting port 111. This design makes the maintenance process more convenient, allowing maintenance personnel to quickly replace the switch assembly 20 without disassembling the entire range hood 1 or multiple components, thereby reducing maintenance time and costs. At the same time, this design also improves the maintainability of the product and extends the service life of the range hood 1. Optionally, the range hood 1 also includes an exhaust hood, which is installed on the housing 11. The housing 11 is provided with a main air inlet 101, and the switch assembly 20 is located on the side of the air inlet near the exhaust hood.
[0025] Combination Figure 3In some embodiments, the switch assembly 20 includes a mounting base 21 and a switch 22. The switch 22 is mounted on the mounting base 21, and the mounting base 21 is mounted on the housing 11. The switch 22 can be a key switch, a micro switch, etc., and is not specifically limited here. The mounting base 21 can connect to the switch 22 and also to the housing 11. One function of the mounting base 21 is to stably mount the switch 22 inside the housing 11. Through its connection with the housing 11, the mounting base 21 provides a firm support for the switch 22, ensuring that the switch 22 will not loosen due to vibration or external force during the operation of the range hood 1. The mounting base 21 also serves to cover the mounting opening 111, thus forming a user-facing surface. Specifically, by covering the mounting opening 111, the mounting base 21 not only hides the internal mounting structure but also forms a clean user-facing surface. This design not only improves the aesthetic appearance of the range hood 1 but also reduces the possibility of dust and oil entering the housing 11, further enhancing the product's anti-fouling performance.
[0026] In some embodiments, the mounting base 21 includes a mounting plate 211, a first fixing part 212, and a second fixing part 213. The switch 22 is mounted on the first fixing part 212 via a fastener, and the mounting base 21 is mounted on the housing 11 via the first fixing part 212. The first fixing part 212, the second fixing part 213, and the switch 22 are all located on the same side of the mounting plate 211. After the switch assembly 20 is installed on the housing 11, the first fixing plate 211, the second fixing plate 211, and the switch 22 are located inside the housing 11 and are covered by the housing 11. By providing the first fixing part 212 and the second fixing part 213, the mounting base 21, the switch 22, and the housing 11 can be installed and removed during assembly and maintenance by changing the connection relationship between the first fixing part 212 and the housing 11 and changing the connection relationship between the second fixing part 213 and the housing 11. The switch 22 is mounted on the first fixing part 212 via a fastener (such as a screw, a clip, etc.), while the mounting base 21 is connected to the housing 11 via the first fixing part 212 and the fastener. This design ensures that after the switch assembly 20 is installed into the housing 11, the first fixing part 212, the second fixing part 213, and the switch 22 are all located inside the housing 11 and are covered by the housing 11, thus concealing the internal mounting structure.
[0027] In some embodiments, the first fixing part 212 and the second fixing part 213 extend from the fixing plate 211 toward the interior of the housing 11, and the housing 11 is provided with a fixing hole 112 (for connection). Figure 1The fixing member passes through the fixing hole 112 and engages with the first fixing part 212 to install the fixing seat 21 onto the housing 11. The fixing member (such as a screw or clip) passes through the fixing hole 112 on the housing 11 and engages with the first fixing part 212, thereby securely installing the fixing seat 21 inside the housing 11. This design not only ensures the stability of the fixing seat 21 but also makes maintenance and replacement more convenient through a detachable connection. The switch 22 can be engaged with the second fixing part 213 via screws or clips, and the housing 11 can be engaged with the first fixing part 212 via screws or clips. This method enables a detachable connection between the fixing seat 21, the switch 22, and the housing 11. This split design makes the assembly and disassembly of the switch assembly 20 more flexible and also reduces maintenance costs due to switch 22 malfunction.
[0028] Optionally, the mounting hole 112 is located on the side of the housing 11 where the air outlet 102 of the smoke collection assembly 10 is located. In other words, the mounting hole 112 is located on the upper side of the housing 11. Thus, by placing the mounting hole 112 on the upper side of the housing 11, it avoids the surface facing the user. This way, the user will not see any mounting holes or fasteners when using the range hood 1 normally, maintaining the cleanliness and aesthetics of the range hood 1. During maintenance, the design of the mounting hole 112 on the upper side reduces the possibility of it being obstructed by cabinets or walls. Maintenance personnel can more easily access the mounting hole 112 to disassemble and replace the switch assembly 20, thereby improving maintenance efficiency and reducing maintenance difficulty.
[0029] In some embodiments, the first fixing part 212 is plate-shaped and has threaded holes or through holes for connection with a fixing member. The first fixing part 212 is located on the side of the switch 22 near the air outlet 102 of the aforementioned smoke collection assembly 10. In other words, the first fixing part 212 is located above the switch 22. This arrangement not only provides physical shielding for the switch 22, reducing the potential damage to the switch 22 from droplets, but also effectively shields the switch 22 from oil droplets or liquids dripping from above. During the operation of the range hood 1, droplets formed by the condensation of oil fumes or steam may drip from the air outlet 102 side of the smoke collection assembly 10. By placing the first fixing part 212 above the switch 22, these droplets first contact the first fixing part 212, rather than falling directly onto the switch 22. In a kitchen environment, there is a lot of oil fumes and moisture. The shielding effect of the first fixing part 212 can effectively prevent droplets from directly contacting the switch 22, reducing electrical faults caused by droplets.
[0030] In some embodiments, the fixing plate 211 is provided with a button hole 2111, and the switch 22 includes a button portion 221 that extends from the button hole 2111. At least a portion of the button portion 221 is located on the side of the fixing plate 211 away from the housing 11. In this way, the button portion 221 of the switch 22 can be exposed to the outside of the range hood 1, and the user can control the range hood 1 by pressing the button portion 221. By designing the button portion 221 to extend out of the fixing plate 211, the user can directly press the button portion 221 to control the range hood 1, improving the convenience of operation.
[0031] In some embodiments, the side of the fixing plate 211 facing away from the housing 11 forms an operating surface, which is parallel to the front-facing surface of the housing 11. The fixing plate 211 can cover the mounting opening 111 and, together with the housing 11, forms a user-facing surface. The design of the fixing plate 211 not only hides the internal mounting structure but also completely covers the mounting opening 111, forming a clean user-facing surface with the housing 11. This design not only improves the overall aesthetics of the range hood 1 but also reduces the possibility of dust and oil entering the interior of the housing 11, enhancing the product's anti-fouling performance. The side of the fixing plate 211 facing away from the housing 11 and towards the user can be equipped with elements such as buttons, labels, or indicator lights. By integrating these elements onto the operating surface, the user can directly read the information provided by the labels or indicator lights and operate the range hood 1 via the buttons. This design not only improves the convenience of operation but also enhances the user's interactive experience with the device. Indicator lights and labels can provide the user with intuitive device status information, such as the operating status of the range hood 1, whether cleaning is required, and whether a malfunction has occurred. By displaying this information on the control panel, users can quickly understand the equipment's operating status without opening the range hood or inspecting its internal structure, thus improving ease of use and efficiency.
[0032] The operating surface of the fixing plate 211 can be recessed relative to the housing 11, protrude relative to the housing 11, or be flush with the housing 11.
[0033] Specifically, in some embodiments, the operating surface is flush with the front-facing surface of the housing 11. This flush design creates a unified, flat appearance. This makes the front of the range hood 1 look cleaner and smoother, without noticeable protrusions or gaps. The flush design also makes the front surface of the range hood 1 easier to clean. Because there are no noticeable protrusions or depressions, dust and grease are less likely to accumulate, and users can easily wipe the entire surface with a cloth or cleaning tools without worrying about cleaning hard-to-reach areas.
[0034] In some embodiments, the operating surface is further away from the interior of the housing 11 than the front-facing surface of the housing 11. In other words, the fixing plate 211 protrudes from the housing 11, thus forming a protruding operating surface. The protruding operating surface can intuitively indicate the location of the buttons on the range hood 1 to the user. When using the device, the user can easily find and operate the buttons without worrying about accidental operation or searching for the button location. This design can significantly improve the user experience in complex kitchen environments or dimly lit conditions. The surfaces formed by the fixing plate 211 configured as described above are all oriented outwards, making it easier for the user to clean them. Due to the slightly protruding operating surface, it is also easier to reach the surface of the switch assembly 20 during cleaning. The protruding fixing plate 211 is also more convenient to disassemble. Maintenance personnel can more easily access the edges of the fixing plate 211, thereby quickly disassembling the switch assembly 20 for repair or replacement.
[0035] In some embodiments, the operating surface is closer to the interior of the housing 11 than the front-facing surface of the housing 11. In other words, the fixing plate 211 is recessed relative to the housing 11. The recessed operating surface can intuitively indicate the location of the button to the user. When operating, the user can perceive the existence of the recessed area by touch or sight, thereby quickly locating the button. This design not only improves the convenience of operation but also reduces the possibility of misoperation, especially in complex kitchen environments or dimly lit conditions, significantly improving the user experience. Because the operating surface is recessed inside the housing 11, the switch assembly 20 is better protected, reducing the possibility of external contaminants (such as dust, oil, water droplets, etc.) directly contacting the buttons and indicator lights. This design not only extends the service life of the switch assembly 20 but also reduces the risk of short circuits or corrosion caused by contamination, enhancing the reliability and durability of the product.
[0036] In some embodiments, the distance between the operating surface and the front-facing surface of the housing 11 is less than 2 mm. For example, 1.5 mm, 1 mm, or 0.5 mm.
[0037] In some embodiments, the area of the fixing plate 211 is larger than the area of the mounting opening 111, and the fixing plate 211 closes the mounting opening 111.
[0038] In some embodiments, the front-facing surface of the housing 11 and the front-facing operating surface of the fixing plate 211 together form the user-facing surface of the smoke collection assembly 10. In other words, the front side of the smoke hood 1 forms an exposed user-facing surface with the surface of the housing 11 through the fixing plate 211 of the switch assembly 20, without the need for additional plates to fix them. Compared to the prior art, not setting additional plates facilitates the assembly and maintenance of the switch assembly 20. By directly utilizing the fixing plate 211 and the surface of the housing 11 to form the user-facing surface, the design of the smoke hood 1 is simpler. This design reduces the number of parts, lowers production costs, and also reduces the assembly complexity and failure risk that may be caused by additional plates. Not setting additional plates makes the assembly and maintenance process of the switch assembly 20 more direct and convenient. Maintenance personnel can quickly disassemble and assemble the switch assembly 20 without removing additional plates. This design not only improves maintenance efficiency but also reduces the risk of component damage due to frequent disassembly and assembly, extending the service life of the equipment.
[0039] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
