They are usually installed above the kitchen stove and can quickly extract the exhaust gas produced by the gas stove and the oil fumes generated during cooking, thereby purifying the kitchen environment and improving people's comfort while cooking.

[0003] Existing side-suction range hoods are usually equipped with a flip-up air guide plate assembly. When the range hood is not in operation, the air guide plate assembly covers the oil fume inlet of the smoke collection chamber to keep the panel of the range hood intact. When the range hood is in operation, the air guide plate assembly is flipped to an outward tilted open state, exposing the oil fume inlet, so that oil fumes can enter the smoke collection chamber through the oil fume inlet to achieve waste oil filtration and oil fume extraction.

[0004] However, in the existing structure of range hoods, the hinge assembly is exposed when the air guide plate assembly is opened. Users can see the hinge assembly from the outside, which affects the aesthetics. In addition, the oil fumes are also prone to condensing at the hinge assembly, which can affect the rotation of the air guide plate assembly and affect the user experience. Utility Model Content

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] As people's living standards improve, range hoods have become an indispensable appliance in the kitchen. They are usually installed above the kitchen stove and can quickly extract the exhaust gas produced by the gas stove and the oil fumes generated during cooking, thereby purifying the kitchen environment and improving people's comfort while cooking.

[0039] This utility model provides a range hood, such as Figures 1-4As shown, the range hood includes a smoke collection hood assembly 1, a hinge assembly 2, and an air guide plate assembly 3. The smoke collection hood assembly 1 includes a smoke collection hood body 11, with a front opening forming a smoke inlet. The hinge assembly 2 includes a first hinge 21 and a second hinge 22 that are rotatably connected. The first hinge 21 is fixedly connected to the smoke collection hood, and the second hinge 22 is fixedly connected to the air guide plate assembly 3. The air guide plate assembly 3 can be flipped through the hinge assembly 2. When the air guide plate assembly 3 is in the open position, the smoke inlet is exposed, and the range hood can draw away the smoke through the smoke inlet. When the air guide plate assembly 3 is in the closed position, the air guide plate assembly 3 and the outer surface of the smoke collection hood body 11 are joined to form a complete exterior surface.

[0040] like Figure 2 and Figure 5 As shown, the smoke hood assembly 1 also includes a top plate 12, the lower surface of which forms a mounting surface. The top plate 12 is fixedly mounted on the top surface of the smoke hood body 11. In order to stably fix the first hinge 21 on the mounting surface of the top plate 12, the range hood also includes a fixing assembly 4. The fixing assembly 4 includes a first fixing plate 41, which is provided with a first fixing groove 42. The first fixing groove 42 extends to one side of the first fixing plate 41 to form a mounting opening 45. The first fixing plate 41 is fixedly mounted on the mounting surface, and the first hinge 21 is disposed in the first fixing groove 42 through the mounting opening 45 and fixedly connected to the first fixing plate 41.

[0041] The fixing component 4, by creating a first fixing groove 42 on the first fixing plate 41 and fixing the first fixing plate 41 to the mounting surface, allows the first hinge 21 of the hinge assembly 2 to be fixed in the first fixing groove 42, thereby concealing the first hinge 21. Furthermore, the clamping structure between the top plate 12 and the fixing component 4 increases the fixing area of ​​the first hinge 21, improving overall rigidity. By setting the fixing component 4, the range hood conceals the first hinge 21 of the hinge assembly 2 under the top plate 12, ensuring that the user cannot directly observe the existence of the hinge assembly 2, maintaining a simple and clean appearance. It also reduces the amount of oil fumes condensed on the hinge assembly 2, ensuring smooth rotation of the air guide plate assembly 3 and improving the user experience.

[0042] like Figure 2 and Figure 3 As shown, in order to improve the reliability of the connection between the air guide plate assembly 3 and the smoke collection hood assembly 1 and the smoothness of rotation, the range hood includes two hinge assemblies 2. The two hinge assemblies 2 are spaced apart along the rotation axis of the air guide plate assembly 3. Through the two fixed points at the far ends, the slight deflection or displacement of the air guide plate assembly 3 when the single-sided hinge assembly 2 rotates can be effectively eliminated, avoiding the possible misalignment of the air guide plate assembly 3 due to long-term use, and ensuring the regularity of the appearance and the stability of the function of the product throughout its entire life cycle.

[0043] Preferably, the upper surface of the first fixing plate 41 is a contoured surface, which is designed based on the lower surface of the top plate 12 at the fixing position of the first fixing plate 41, so as to ensure that the first fixing plate 41 can fit tightly against the top plate 12 and ensure the stability of the fixing between the first fixing plate 41 and the top plate 12.

[0044] like Figure 5 As shown, the fixing component 4 further includes a second fixing plate 43, which is connected to the first fixing plate 41 via a first transition plate 44 to form a first fixing groove 42. Preferably, the fixing component 4 is integrally formed by stamping, which can improve processing efficiency and reduce production costs.

[0045] In this embodiment, the depth of the first fixing groove 42 is greater than or equal to the thickness of the first hinge 21, so as to ensure that the first hinge 21 can be fixed in the fixed space formed by the top plate 12 and the first fixing groove 42, while not interfering with the top plate 12 and the fixing component 4, and ensuring that the first fixing plate 41 can be attached and fixed to the top plate 12.

[0046] like Figure 4 and Figure 5 As shown, the depth of the first fixing groove 42 is equal to the thickness of the first hinge 21. The first hinge 21 includes a first abutting surface 211 and a second abutting surface 212. The first abutting surface 211 abuts against the mounting surface, and the second abutting surface 212 abuts against the bottom of the first fixing groove 42, that is, against the second fixing plate 43. This structure allows the top plate 12 and the second fixing plate 43 to simultaneously clamp the first hinge 21, thereby ensuring the stability of the second hinge 22. This design evenly distributes various forces on the first hinge 21 (such as the force of gravity and the torque of opening and closing) to a larger area of ​​the top plate 12 and the dedicated reinforcing member (fixing component 4), greatly improving the local rigidity of the mounting point of the air guide plate assembly 3 and the overall structural stability, making its operation more stable and without abnormal noise.

[0047] In some embodiments, the first fixing plate 41 is fixedly connected to the mounting surface by adhesive. The advantages of adhesive fixing are that it eliminates the need for drilling or adding additional connectors, does not increase weight, facilitates lightweight design, and results in a smooth, flat, and aesthetically pleasing surface without weld marks or screw heads.

[0048] In some embodiments, the first fixing plate 41 is fixedly connected to the mounting surface by welding. The advantage of welding is that welding can provide a strong connection between the first fixing plate 41 and the top plate 12, and it can achieve high-speed, mass production without the need for additional connectors (such as screws and nuts), resulting in low material costs.

[0049] In some embodiments, the first fixing plate 41 is fixedly connected to the mounting surface by bolts. The advantages of bolted connections are that they can be easily disassembled and reassembled, facilitate maintenance, replacement and adjustment, the connection quality depends on standard parts and preload, are easy to control and inspect, loose screws are easy to find, and they have high reliability.

[0050] To secure the first hinge 21, a fixing hole 213 is provided in the first hinge 21. A fixing screw passes through the mounting surface and the fixing hole 213 sequentially and is threadedly connected to the second fixing plate 43. The fixing screw passing through the fixing hole 213 restricts the horizontal freedom of the first hinge 21. Simultaneously, the top plate 12 and the second fixing plate 43 clamp and secure the first hinge 21, restricting its vertical freedom. This secures the first hinge 21 and ensures its stability.

[0051] Furthermore, the fixing screw is threaded into the fixing hole 213. That is, the fixing hole 213 of the first hinge 21 is provided with internal threads, and the fixing screw can simultaneously fix the first hinge 21 and the second fixing plate 43. The fixing screw can not only fix the first hinge 21 through the internal threads of the fixing hole 213, but also increase the contact area between the fixing screw and the first hinge 21 due to the internal threads of the fixing hole 213, thereby further improving the stability of the first hinge 21.

[0052] In this embodiment, the first abutting surface 211 and the second abutting surface 212 of the first hinge 21 are connected by a second transition plate 214, and a fixing hole 213 is formed on the second abutting surface 212. That is, the second abutting surface 212 abuts against the second fixing plate 43, so that when the fixing screw is threadedly connected to both the second abutting surface 212 and the second fixing plate 43, there is no gap between the second abutting surface 212 and the second fixing plate 43, which can effectively avoid local deformation caused by different fastening forces on the second abutting surface 212 and the second fixing plate 43.

[0053] It is worth noting that the fixing screws are countersunk screws. As the countersunk screws pass through the top plate 12 and subsequently through the fixing hole 213 and the second fixing plate 43, the head of the countersunk screw is completely recessed into the top plate 12, flush with its surface. This ensures that no exposed fixing screws or other fasteners are visible from any external perspective (whether viewed from the front, side, or top). This "embedded" installation method not only achieves a secure fixation but also cleverly conceals the mechanical structure.

[0054] Understandably, hinge assembly 2 typically first secures the second hinge 22 to the air guide plate assembly 3, and then inserts the first hinge 21 into the fixing slot for fixation. For example... Figure 5As shown, in order to facilitate the operation of the operator, the second fixing plate 43 includes a fixing part 431 and a guide part 432. The fixing screw is threadedly connected to the fixing part 431. The guide part 432 is disposed on the side of the fixing part 431 near the mounting port 45. Along the direction away from the fixing part 431, the guide part 432 is inclined in the direction away from the mounting surface.

[0055] The inclined guide part 432 keeps the mounting opening 45 open. When the operator inserts the first hinge 21 into the fixing slot, even if the first hinge 21 has a certain deviation, it can still enter the fixing slot under the guidance of the guide part 432, thus improving assembly efficiency.

[0056] like Figure 6 As shown, the top plate 12 includes a main plate 121 and a baffle plate 122 set at an angle to the main plate 121. The smoke collection hood assembly 1 also includes a smoke collection hood body 11. The baffle plate 122 is set on the front side of the smoke collection hood body 11. The baffle plate 122 has an opening 123. The first hinge 21 passes through the opening 123 to be installed in the first fixing groove 42.

[0057] The shield 122 serves two purposes: firstly, it provides a quick alignment reference when assembling the main board 121 onto the smoke hood body 11; secondly, it shields the fixing component 4 and the first hinge 21, improving aesthetics. The clearance 123 allows the first hinge 21 to smoothly enter the fixing slot.

[0058] To further conceal the hinge assembly 2, the air guide plate assembly 3 includes an air guide plate body and a decorative panel 31. The decorative panel 31 is spaced apart from the air guide plate body and located on the side of the air guide plate body facing away from the smoke collection hood. The second hinge 22 is disposed between the decorative panel 31 and the air guide plate body. By using the air guide plate body and the decorative panel 31 to cover the second hinge 22, the user cannot see the second hinge 22 whether looking from the outside or the inside. In other words, the range hood only exposes the pivot of the hinge assembly 2, greatly reducing the amount of oil fumes condensed on the hinge assembly 2 and ensuring that the hinge assembly 2 can rotate smoothly for a long time.

[0059] It is understandable that the decorative panel 31 is generally made of glass or polymer material, and the air guide plate is made of oleophobic polymer material. If the air guide plate body or the decorative panel 31 is directly fixed to the second hinge 22, it is easy for it to break.

[0060] like Figure 3As shown, to solve the above problems, the air guide plate assembly 3 also includes a support frame 32, which is disposed between the air guide plate body and the decorative panel 31. The second hinge 22 is fixedly connected to the support frame 32. The support frame 32 is made of a high-strength material, such as metal, thereby ensuring the reliability of the connection between the air guide plate assembly 3 and the second hinge 22.

[0061] In this embodiment, the support frame 32 can also house structures such as a touch panel, circuit board, and drive components inside the air guide plate assembly 3. This not only frees up internal space for the smoke collection chamber assembly but also makes the touch panel, circuit board, and drive components less susceptible to corrosion by oil fumes, thus improving their service life.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
