[0066] The range hood and the elastic buckle for realizing the embedded installation of the range hood provided by the embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0067] First, in combination with Figures 1 to 9 The range hood provided by the embodiments of the present utility model will be described.

[0068] As Figure 1As shown in the figure, an embodiment of the present utility model provides an oil fume machine 2 that can achieve fully embedded installation.

[0069] As Figure 2 shown, the oil fume machine 2 provided by the embodiment of the present utility model includes a main box 21, a smoke collecting device 22, and a movable plate glass assembly 23. The smoke collecting device 22 is located below the main box 21, and the movable plate glass assembly 23 is pivotally connected to the position of the smoke inlet of the smoke collecting device 22 through a hinge to open or close the smoke inlet of the smoke collecting device 22. When the movable plate glass assembly 23 is closed, the bottom surface of the oil fume machine 2 is the glass plane, which improves the overall visual effect. When the movable plate glass assembly 23 is open, it is in an outwardly inclined state, as Figure 2 and Figure 3 shown in the figure.

[0070] As Figure 2 , Figure 6 and Figure 7 shown, the main box 21 includes a main box enclosure 212, a decorative cover 211, a power box 213, a fan, a air duct 214, etc. The main box enclosure 212 includes a front enclosure 2122, a top enclosure 2121, a side enclosure 2123, and a back enclosure 2124. The top enclosure 2121 and the front enclosure 2122 are made into an integral structure through a bending process, and the side enclosure 2123 and the back enclosure 2124 are made into an integral structure through a bending process. Each plate member is connected by fasteners and encloses a space for accommodating the fan. The decorative cover 211 is in a U-shaped structure and covers the outer periphery of the front enclosure 2122 and the side enclosure 2123, improving the overall visual effect of the main box 21. The fan includes a fan housing, a wind wheel arranged in the fan housing, a motor, etc. The fan housing constructs the air duct 214, and the outlet of the air duct 214 passes through the top enclosure 2121 and is connected to the exhaust pipe. The power box 213 is fixedly connected above the top enclosure 2121.

[0071] As Figure 2 and Figure 4 shown, the smoke collecting device 22 includes an outer enclosure 221. The outer enclosure 221 includes a front plate 2211, a top plate 2212, a back plate 2213, and a side plate 2215 (not shown). After each plate member is connected, a receiving space is formed. An oil net, a lamp panel 227, a first oil receiving plate 226, a reinforcing beam 224, a second oil receiving plate 225, a sealing cover 223, a side plate support frame 222, etc. are installed in the receiving space.

[0072] Specifically, as Figure 8As shown in the figure, the first oil receiving plate 226 is configured with a first step structure 2261, a second step structure 2262 located below the first step structure 2261, and a bend 2263 located at the top edge of the first step structure 2261. The bend 2263 is used for fixedly connecting with the front plate 2211. Both the first step structure 2261 and the second step structure 2262 are provided with enclosures 2264 to enable them to have a certain flow guiding function. During installation, the first step structure 2261 is installed below the front enclosure plate 2122 of the main box 21, so that the oil droplets adhering to the inner wall of the front enclosure plate 2122 can drip onto the first step structure 2261 under the action of gravity.

[0073] As Figure 5 shown in the figure, two reinforcing beams 224 are provided and are relatively installed below the side enclosure plate 2123. The reinforcing beam 224 is configured with a first oil guiding groove 2231 that slopes downward from front to back. The first end of the first oil guiding groove 2231 is connected to the first step structure 2261 of the first oil receiving plate 226, and the second end of the reinforcing beam 224 is connected to the back plate 2213. A second oil receiving plate 225 is connected to the bottom edge of the back plate 2213. The second oil receiving plate 225 is provided with an oil receiving groove 2251. The second end of the first oil guiding groove 2231 is located above the oil receiving groove 2251 and has a certain distance from the back plate 2213, facilitating the oil in the first oil guiding groove 2231 to drip smoothly onto the second oil receiving plate 225 below. In addition, the first oil guiding groove 2231 is located below the side enclosure plate 2123 and is also used to directly receive the oil droplets dripping from the inner wall of the side enclosure plate 2123 of the main box 21. Specifically, as Figure 6 or Figure 7 shown by the black arrows in the figure, some of the oil droplets dripping from the front enclosure plate 2122 and the oil droplets (not shown) dripping from the side enclosure plate 2123 can all flow through the first oil guiding groove 2231 and converge into the oil receiving groove 2251.

[0074] In addition, a wire routing hole 2242 is also provided on the reinforcing beam 224 to facilitate wire routing between the main box 21 and devices such as motors. A positioning portion 2243 is also provided on the reinforcing beam 224. The positioning portion 2243 in this embodiment is a horizontal bend formed on the reinforcing beam 224. The horizontal bend extends towards the middle of the range hood 2 and has a positioning surface facing upward horizontally, which is used for positioning the side enclosure plate 2123. During installation, the side enclosure plate 2123 is installed inside the reinforcing beam 224 and above the first oil guiding groove 2231, and the bottom edge of the side enclosure plate 2123 directly abuts against this horizontal positioning surface.

[0075] As Figure 3As shown in the figure, on the inner side of the second oil drip tray 225 (the direction in which the second oil drip tray 225 faces the front plate 2211), a lamp board 227 is also connected. The lamp board 227 is used to install light sources such as lamp beads. The lamp board 227 itself has several bending structures, which wrap the top edge of the second oil drip tray 225 and are also used to support the oil screen.

[0076] As Figure 7 and Figure 9 shown in the figure, the smoke collecting device 22 further includes two sealing covers 223. Each sealing cover 223 is respectively connected to the first oil drip tray 226, the strengthening beam 224, the back plate 2213 and the second oil drip tray 225, thereby constructing a smoke collecting cavity. Specifically, at the second step structure 2262 of the first oil drip tray 226, a retaining structure 2264 is provided by bending process, and the retaining structure 2264 is connected to the sealing cover 223 by screws. In addition, as Figure 8 shown in the figure, the two ends in the horizontal direction of the second step structure 2262 extend outward and forward in sequence to form an oil outlet part 22621. As Figure 9 shown in the figure, a second oil guiding groove 2231 is provided on the inner side of the sealing cover 223. Combining Figure 8 and Figure 9 , the oil outlet part 22621 of the second step structure 2262 is communicated with the first end of the second oil guiding groove 2231, and the second end of the second oil guiding groove 2231 extends above the oil receiving groove 2251 of the second oil drip tray 225 and is thus communicated with the oil receiving groove 2251.

[0077] As Figure 7 shown by the black arrow in the figure, the front apron 2122 - the first step structure 2261 - the first oil guiding groove 2231 - the oil receiving groove 2251 form a first oil path. As Figure 7 shown by the gray arrow in the figure, the front apron 2122 - the first step structure 2261 - the second step structure 2262 - the second oil guiding groove 2231 - the oil receiving groove 2251 form a second oil path. In this way, the range hood 2 of the present utility model is provided with parallel double oil paths, which can improve the grease collection effect.

[0078] As Figure 3 shown in the figure, a front strengthening beam 228 is further connected below the first oil drip tray 226. The front strengthening beam 228 has an inclined surface, and the inclined surface is set to be parallel to the inner side surface of the movable plate glass assembly 23 of the range hood 2 after being unfolded, so as to enhance the aesthetics.

[0079] As Figure 2 , Figure 4 , Figure 5 , Figure 12 , Figure 13As shown, the range hood 2 further includes a plurality of baffles 2214. The baffles 2214 are L-shaped and are connected to the gap between the smoke collecting device 22 and the inner side wall of the preset installation cavity 15. The size of the baffles 2214 depends on the width of the gap, so as to minimize the gap as much as possible and make the range hood 2 more visually coordinated with the cabinet 1 after installation. It should be noted that the baffle 2214 also includes a baffle for blocking the gap between the back plate 2213 and the back wall of the cabinet 1.

[0080] By adopting the range hood structure in the present utility model, the effect of collecting grease in parallel with a double oil path is achieved, the grease collection effect is improved, and the overall structure is more compact and lightweight, facilitating the full-embedded installation of the entire range hood 2, thereby enhancing the overall aesthetics.

[0081] The following will combine Figure 1 、 Figures 10 to 17 to illustrate how the present utility model realizes the embedded installation of the range hood 2.

[0082] First, the structure of the cabinet 1 for installing the range hood 2 in the present utility model will be described.

[0083] As Figure 1 、 Figures 10 to 12 shown, only the part of the cabinet 1 for installing the range hood 2 is shown in the figure. This part of the cabinet 1 includes a left cabinet board 11, a top cabinet board 12, a right cabinet board 13, and a front cabinet board (not shown). The front cabinet board can be set as a whole board structure or in a double-door manner. After the cabinet boards are connected, a preset installation cavity 15 is formed, and the preset installation cavity 15 is used to accommodate the range hood 2. In the embodiment of the present utility model, the cabinet 1 further includes a support member 14. As Figure 10 and Figure 11 shown, the cross-sectional shape of the support member 14 is L-shaped, and it is fixedly connected to the inner sides of the left cabinet board 11 and the right cabinet board 13 through fasteners such as screws to form a horizontally upward support surface 141. The support surface 141 is used to cooperate with the elastic buckle 24 provided on the side plate 2215 of the range hood 2 to realize the full-embedded installation of the range hood 2. The elastic buckle 24 is arranged to be able to converge inward to avoid the support member 14 during the process of the range hood 2 being loaded into the preset installation cavity 15 from bottom to top, and be supported by the support surface 141 after rebounding, so as to be embedded and installed into the preset installation cavity 15 by means of the elastic buckle 24.

[0084] The elastic buckle 24 provided in the embodiment of the present utility model includes a base body 241, a support member 242, a deformation member 243, a movable member 244, etc.

[0085] Specifically, as Figures 12 to 15 shown, the base body 241 can be detachably connected to the side plate 2215 of the range hood 2 to be installed. As Figure 15As shown in the figure, the base body 241 is an approximately box-shaped structure formed by a bending process, including a front wall 2411, a bottom wall 2412, side walls 2413, and a back wall 2414. A clamping hole 24111 is provided on the front wall 2411 for mating connection with a clamping hook 24311 of the deformation part 243. A through hole is provided on the bottom wall 2412 for a bolt 246 to pass through. A flanging 24132 and an oblong hole 24131 are provided on the side wall 2413. The flanging 24132 is used for detachable connection with a side plate 2215 of the range hood 2 through a fastener, and the oblong hole 24131 is used for adjusting the height of a movable part 244 of the elastic buckle 24.

[0086] As Figure 15 As shown in the figure, the support member 242 has a U-shaped structure, including a vertical part 2421 and a horizontal part 2422, and is integrally installed into the space surrounded by the base body 241. A fastener installation hole for connecting with the movable part 244 is provided on the vertical part 2421 of the support member 242, and a through hole for installing a nut is provided on the horizontal part 2422 of the support member 242. During installation, the support member 242 is installed into the space of the base body 241, and the support member 242 and the base body 241 are fixedly installed through a rivet nut and a bolt 246.

[0087] The deformation part 243 has a V-shaped elastic sheet structure, which includes a connecting part 2431 and a deformation part 2432. The connecting part 2431 is connected to the base body 241, and the detachable connection between the two is specifically realized by the cooperation of a clamping hook 24311 provided on the connecting part 2431 and a clamping hole 24111 on the front wall 2411 of the base body 241. The deformation part 2432 is cantilevered relative to the connecting part 2431, and thus can be cantilevered relative to the base body 241, so that the deformation part 243 has elasticity.

[0088] The movable part 244 includes a connecting arm 2441 and a cantilever 2442. The connecting arm 2441 passes over the front wall 2411 of the base body 241 and extends to the rear wall of the base body 241. A fastener installation hole 24411 is formed on the connecting arm 2441, which can be adapted to the fastener installation hole provided on the support member 242, so that the movable part 244 can be movably connected to the support member 242 through a screw 247. The screw 247 passes through the oblong hole 24131 on the base body 241. After installation, the cantilever 2442 of the movable part 244 extends out of the base body 241 and is cantilevered relative to the base body 241. As Figure 14As shown in the figure, in the installed state, the deformable member 243 is disposed between the movable member 244 and the base body 241. When the cantilever 2442 of the movable member 244 is subjected to an extrusion force, it will contract towards the base body 241. During this process, the movable member 244 rotates relative to the base body 241 around the axis of the screw 247, and will squeeze the deformable member 243, causing the deformable member 243 to contract. When the extrusion force applied to the cantilever 2442 disappears, the movable member 244 will return to its original state under the elastic recovery force of the deformable member 243.

[0089] As Figure 12 and Figure 13 As shown in the figure, when the range hood 2 is installed in an embedded manner, first install the above-mentioned elastic buckle 24 on the side plate 2215 of the range hood 2. Two to three such elastic buckles 24 are installed on one side plate 2215 of the range hood 2, and a total of 4 to 6 such elastic buckles 24 are installed. During installation, the entire range hood 2 is inserted into the preset installation cavity 15 from bottom to top. During the insertion process, the movable member 244 of the elastic buckle 24 will first be squeezed by the supporting member 14 and contract towards the side wall of the range hood 2 to avoid the supporting member 14. When it gradually crosses the edge of the supporting member 14 from bottom to top, the extrusion force gradually disappears, and it will rebound under the action of the deformable member 243 and be supported by the supporting surface 141, thereby realizing the embedded installation of the entire range hood 2. When disassembly and maintenance are required, open the front cabinet panel and pull the range hood 2 forward, so that the range hood 2 slides out from back to front under the guidance of the supporting member 14. In this way, through the setting of the elastic buckle 24, the disassembly and assembly steps of the range hood 2 are simplified, and the installation efficiency can be effectively improved.

[0090] As Figures 15 to 17 As shown in the figure, the supporting member 242 of the elastic buckle 24 in the embodiment of the present invention is fixedly connected to the base body 241 through a rivet bolt 246, so that the relative position between the supporting member 242 and the base body 241 can be adjusted. Specifically, as Figure 15 As shown in the figure, the nut 245 is fixedly connected to the supporting member 242, and the bolt 246 passes through the bottom wall 2412 of the base body 241 and is connected to the nut 245. Since the screw 247 connected to the supporting member 242 and the vertically extending long circular hole 24131 provided on the base body 241 are not tightly connected, the relative height between the supporting member 242 and the base body 241 can be adjusted by screwing the bolt 246, and then the relative position between the movable member 244 and the base body 241 can be adjusted. As Figure 16 As shown in the figure, taking the bottom wall 2412 of the base body 241 as the reference O for comparison, at this time, the end of the movable member 244 is located below the bottom wall 2412 of the base body 241, and H2 is a negative value. As Figure 17As shown, at this time, the end of the movable member 244 is located above the bottom wall 2412 of the base body 241, and H1 is a positive value. When the base body 241 of the elastic buckle 24 is installed at the same position of the range hood 2, the overall height of the range hood 2 can be adjusted only by adjusting the height of the support member 242 of the elastic buckle 24. Thus, during the installation of the range hood 2, the height adjustment of the range hood 2 can be conveniently achieved. In this way, even if the installation position of the supporting member 14 is slightly deviated, the range hood 2 can be conveniently adjusted accordingly, making the entire installation process smoother, with higher installation efficiency and better overall visual appearance after installation.

[0091] It should be noted that the deformation member 243 is detachably connected to the base body 241, specifically detachably connected to the base body 241 through the hook 24311. It can be understood that the deformation member 243 can also be detachably connected to the base body 241 through fasteners, or fixedly connected by welding or other means.

[0092] In the above example, the supporting member 14 is fixedly connected to the inner side surface of the side wall of the preset installation cavity 15. Alternatively, the supporting member 14 can also be embedded and installed in the side wall of the preset installation cavity 15. For example, a strip-shaped groove extending in the front-rear direction and opening inward is formed in the side wall, and a U-shaped channel steel is fixedly connected in the strip-shaped groove as a support member, which can also achieve the embedded installation of the range hood 2.

[0093] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or replacements to the relevant technical features, and the technical solutions after these changes or replacements will fall within the protection scope of the present invention.
