Description

Technical Field

[0001] This utility model relates to the field of integrated cabinet embedded range hoods, specifically a range hood connection structure based on a smart home integrated cabinet. Background Technology

[0002] With the development of smart homes and integrated kitchens, range hoods are increasingly being integrated into cabinet structures. However, traditional range hoods mostly use fixed-length hoods, which often present the following problems during installation: First, the fixed hood length cannot be flexibly adjusted according to the cabinet height, often requiring on-site cutting and processing, making construction cumbersome; second, if the cabinet is tall and the fixed hood length is insufficient, the internal flue structure is often exposed, affecting aesthetics and sealing performance; third, variations in the width of different hood specifications can also cause inaccurate matching of the range hood's installation position, affecting the overall fit between the range hood and hood. Therefore, there is an urgent need for a simple, flexible, and highly compatible range hood connection structure to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a range hood connection structure based on a smart home integrated cabinet to solve the technical problems mentioned in the background art.

[0004] Based on the above ideas, this utility model provides the following technical solution:

[0005] A range hood connection structure based on a smart home integrated cabinet, characterized in that it includes:

[0006] The cabinet, the range hood installed inside the cabinet, the liftable range hood fixedly connected to the range hood, and the fixed range hood fixedly installed on the top of the cabinet and connected to the wall;

[0007] The lifting smoke hood is fitted over the outside of the fixed smoke hood and slidably connected to it. The outer surface of the fixed smoke hood is provided with a sliding strip, and the inner side of the lifting smoke hood is provided with a corresponding sliding groove. The sliding strip and the sliding groove slide together to realize the vertical sliding connection between the fixed smoke hood and the lifting smoke hood.

[0008] Preferably, the lower two sides of the cabinet are respectively provided with second threaded plates.

[0009] Each of the second threaded plates is slidably mounted with a right-angle plate.

[0010] The bottom of the right-angle plate is slidably connected to the second threaded plate, and the side is slidably connected to the first threaded plate.

[0011] The first threaded plate is fixedly connected to the lifting fume hood.

[0012] Preferably, the first threaded plate has a first threaded hole, and the second threaded plate has a second threaded hole.

[0013] The screws pass through the side and bottom surfaces of the right-angle plate respectively and are threaded into the first and second threaded holes.

[0014] The height of the liftable fume hood relative to the cabinet and its installation width can be adjusted by rotating the screw.

[0015] Preferably, the first threaded plate and the right-angle plate are in a perpendicular sliding fit.

[0016] The second threaded plate and the right-angle plate are in a horizontal sliding fit.

[0017] Preferably, the lifting fume hood is a metal plate structure, and the whole is in the shape of a square tube; the fixed fume hood is located inside the lifting fume hood and is offset from its bottom end.

[0018] Preferably, the sliding fit between the slider and the groove is a linear guide rail fit or a U-shaped groove fit.

[0019] Working principle:

[0020] This invention achieves adaptive adjustment of the height of the smoke hood by using a sliding connection structure between the lifting smoke hood and the fixed smoke hood, thereby adapting to the installation space of integrated cabinets of different specifications.

[0021] Specifically, the fixed range hood is installed on the top of the cabinet and fixedly connected to the wall, its position remaining stationary. The retractable range hood is fixedly connected to the range hood, completely covering the outside of the fixed range hood. A sliding groove inside the retractable range hood engages with a sliding strip on the outer surface of the fixed range hood, allowing the retractable range hood to slide vertically relative to the fixed range hood. This allows users to manually or electrically adjust the position of the retractable range hood according to the actual installation height of the cabinet or aesthetic preferences, ensuring it fits snugly against the lower edge of the cabinet, thus concealing all exposed parts of the fixed range hood and achieving a visually appealing, unified, recessed installation.

[0022] Based on this, the lower sides of the cabinet are equipped with an adjustable installation connection structure consisting of a second threaded plate, a right-angle plate, and a first threaded plate. The second threaded plate is fixed inside the cabinet, while the right-angle plate slides in contact with both the bottom of the second threaded plate and the side of the first threaded plate. The first threaded plate is fixed to the side wall of the lifting fume hood by screw threads.

[0023] By rotating the screws, the right-angle plate can be finely adjusted in both the horizontal and vertical directions, thereby changing the installation height and lateral spacing of the lift-up fume hood. This structure can simultaneously solve the problem of inconsistent vertical and horizontal spacing within the cabinet, offering excellent installation compatibility and adjustment precision.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] By employing a nested sliding structure of grooves and strips between the lift-up range hood and the fixed range hood, the lift-up range hood can slide up and down along the outer wall of the fixed range hood. This allows for flexible adjustment based on the specific installation height of the cabinet, avoiding structural exposure or secondary cutting issues caused by insufficient range hood length, significantly improving adaptability and installation convenience. The structure utilizes a sliding fit between a first threaded plate, a second threaded plate, and a right-angle plate, with lateral adjustment achieved through screw thread limits. This adapts to cabinets and lift-up range hoods of varying widths, solving the problems of fixed installation width and poor adaptability inherent in traditional range hood structures. The double-threaded connection provides both installation positioning and shock absorption, ensuring the stability and safety of the range hood during long-term use and preventing wobbling and misalignment. This structural design eliminates the need for custom processing based on cabinet dimensions, making it suitable for standardized production. This enhances the modular assembly capability of range hoods in smart home integrated cabinets, shortens installation cycles, and reduces labor and cost inputs. After adjustment, the lifting fume hood can completely cover the exposed part of the fixed fume hood, resulting in a unified and neat overall visual effect. This effectively avoids problems such as oil fume leakage or dust accumulation, further enhancing the product's user experience and hygiene performance. Attached Figure Description

[0032] like Figure 1-5 ,

[0033] A range hood connection structure based on a smart home integrated cabinet, characterized in that it includes:

[0034] Cabinet 1, range hood 2 installed inside the cabinet 1, liftable range hood 3 fixedly connected to the range hood 2, and fixed range hood 4 fixedly installed on the top of the cabinet 1 and connected to the wall;

[0035] The lifting smoke hood 3 is fitted over the outside of the fixed smoke hood 4 and slidably connected to it. The outer surface of the fixed smoke hood 4 is provided with a slide bar 11, and the inner side of the lifting smoke hood 3 is provided with a corresponding slide groove 12. The slide bar 11 and the slide groove 12 slide together to realize the vertical sliding connection between the fixed smoke hood 4 and the lifting smoke hood 3.

[0036] Specifically, the lower two sides of the cabinet 1 are respectively provided with second threaded plates 8.

[0037] Each of the second threaded plates 8 is slidably mounted with a right-angle plate 5.

[0038] The bottom of the right-angle plate 5 is slidably connected to the second threaded plate 8, and the side is slidably connected to the first threaded plate 6.

[0039] The first threaded plate 6 is fixedly connected to the lifting fume hood 3.

[0040] Specifically, the first threaded plate 6 is provided with a first threaded hole 7, and the second threaded plate 8 is provided with a second threaded hole 9.

[0041] Screw 10 passes through the side and bottom surfaces of the right-angle plate 5 respectively and is threaded into the first threaded hole 7 and the second threaded hole 9.

[0042] The height of the lifting fume hood 3 relative to the cabinet 1 and its installation width can be adjusted by rotating screw 10.

[0043] Specifically, the first threaded plate 6 and the right-angle plate 5 are in a perpendicular sliding fit.

[0044] The second threaded plate 8 and the right-angle plate 5 are in a horizontal sliding fit.

[0045] Specifically, the lifting smoke hood 3 is a metal plate structure, and the whole is in the shape of a square tube; the fixed smoke hood 4 is located inside the lifting smoke hood 3 and is offset from its bottom end.

[0046] Specifically, the sliding fit between the slide bar 11 and the slide groove 12 is a linear guide rail fit or a U-shaped slide groove fit.

[0047] like Figure 4 As shown, the fixed smoke hood 4 is provided with a sliding strip 11 on the outside, and the lifting smoke hood 3 is provided with a matching sliding groove 12 on the inside. Through sliding cooperation, the lifting smoke hood 3 can slide up and down relative to the fixed smoke hood 4, thereby achieving adaptive installation at different heights.

[0048] like Figure 3 and Figure 4 As shown in the enlarged view, the lower two ends of the cabinet 1 are provided with second threaded plates 8, on which right-angle plates 5 are slidably installed. The right-angle plates 5 are slidably connected to the side of the first threaded plate 6. The first threaded plate 6 is connected and fixed to the lifting fume hood 3 by welding or screwing.

[0049] The first threaded plate 6 and the second threaded plate 8 are respectively provided with a first threaded hole 7 and a second threaded hole 9. The right-angle plate 5 is provided with a corresponding through hole. The screw 10 passes through the right-angle plate 5 and is threadedly connected to the corresponding threaded hole. By adjusting the screw rotation, the first threaded plate 6 and the right-angle plate 5 can slide up and down, thereby adjusting the height of the lifting fume hood 3. At the same time, the right-angle plate 5 and the second threaded plate 8 can be laterally adjusted through sliding cooperation to adapt to cabinets of different widths.

[0050] This structure allows for flexible installation without requiring modifications to the fixed fume hood or cutting or customizing of the lifting fume hood. It boasts high installation efficiency, strong reliability, and broad application value.

[0051] Some range hoods use fixed-length hoods, which often lead to problems such as height mismatch, exposed structure, or the need for on-site cutting when installed in smart integrated cabinets of different sizes, failing to meet the requirements for fast and standardized installation. At the same time, the existing structure also lacks effective adjustment means in the width direction, which can easily lead to misalignment or insecure fixing, affecting product stability and service life.

[0052] This invention features a fixed fume hood mounted on top of a cabinet and secured to the wall, while a liftable fume hood is fitted over the fixed hood and slidably connected via a groove and a slider. This allows the liftable hood to slide up and down relative to the fixed hood, flexibly adjusting its installation position according to the cabinet height and achieving adaptive height adjustment. This structure not only eliminates the need for on-site cutting but also ensures complete coverage of the internal structure by the fume hood, effectively improving overall aesthetics and sealing.

[0053] Furthermore, this application includes second threaded plates on both sides of the cabinet, on which right-angle plates are slidably installed. The right-angle plates and the first threaded plate, as well as the second threaded plate, form sliding engagements in the vertical and horizontal directions, respectively. Combined with the limiting adjustment of screws, this allows for fine-tuning of the height and width of the range hood. This structure enables adaptation to cabinets and range hood components of different sizes, significantly improving installation flexibility and stability, and providing an effective technical means for the modular installation of integrated range hoods.
