Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] A range hood is a kitchen appliance installed above the stove to purify the kitchen environment and remove cooking fumes from the kitchen. To control the range hood, some models have a switch box on the inner surface of their flip-up panel. The switch box typically includes a body, a cover, and a switch plate inside the box. The body has an mounting opening, and the cover is installed at the mounting opening.

[0003] However, in related technologies, there are often gaps between the cover and the body of the switch box, especially at the joint between the top edge of the cover and the body. This allows oil fumes to enter the switch box through the gap when the range hood is working, resulting in oil accumulation inside the switch box. This does not meet safety requirements and can also cause oil stains to accumulate on the switch plate inside the switch box, making it prone to failure or corrosion. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a range hood that provides good sealing between the cover and the body, effectively preventing oil fumes from entering the interior of the switch box and forming oil accumulation.

[0005] This application provides a range hood, including:

[0006] Main body of the range hood;

[0007] The panel is rotatably mounted on the main body of the range hood;

[0008] A switch box is disposed on the inner surface of the panel. The switch box includes a box body and a box cover. The box body has an installation opening, and the box cover is installed at the installation opening.

[0009] The top edge of the box cover is provided with an insertion part, which extends from one end of the top edge of the box cover to the other end. The insertion part is inserted into the inner side of the box body through the mounting port and abuts against and fits against the inner wall surface of the box body.

[0010] The range hood provided in this application has a plug-in part on the top edge of the cover, which extends from one end of the top edge of the cover to the other end. The plug-in part is inserted into the inside of the cover through the mounting port and abuts against the inner wall of the cover. This design ensures the sealing of the top edge of the cover and the cover, minimizing gaps between the top edge of the cover and the cover. This effectively prevents oil fumes from entering the interior of the switch box, avoids oil accumulation inside the switch box, meets safety requirements, and prevents oil stains from accumulating on components such as the switch plate inside the switch box, which could lead to failure or corrosion, thus extending the service life of the switch plate and other components inside the switch box.

[0011] In some embodiments, the insertion part is an insertion folded edge formed by pressing the outer surface of the top edge of the box cover toward the inner surface, and the area of ​​the box body located on the top side of the mounting port is a flat area, and the insertion folded edge is inserted into the inner side of the flat area.

[0012] This design ensures that the folded edge can be smoothly inserted into the inner side of the box through the mounting port on the box body, and fits against the inner wall of the flat area on the top side of the mounting port on the box body, improving the convenience of inserting the folded edge on the box cover into the box body; and after the box cover and box body are assembled, the outer surface of the box cover exposed on the outside of the box body is flush or roughly flush with the outer surface of the box body around the mounting port, ensuring that the switch box has a good appearance.

[0013] In some embodiments, the insertion part is an insertion fold formed by pressing the outer surface of the top edge of the cover toward the inner surface, and the area of ​​the box body located on the top side of the mounting opening has a raised insertion groove, and the insertion fold is inserted into the inner side of the insertion groove.

[0014] This design allows for easy insertion of the folded edge onto the inside of the box body by creating raised insertion slots, thus improving the convenience of connecting the folded edge on the lid to the box body.

[0015] In some embodiments, the bottom edge and two opposite side edges of the mounting opening are respectively formed with support flanges extending toward the inner perimeter area of ​​the mounting opening, and the bottom edge and two opposite side edges of the box cover are respectively supported at the corresponding support flanges and fit with the support flanges.

[0016] This design utilizes the three-sided support flanges located at the bottom edge and two opposite side edges of the mounting opening to effectively support the cover. Furthermore, the bottom edge and two opposite side edges of the cover are respectively fitted with the corresponding support flanges to ensure a tight seal between the bottom edge and the box body. Combined with the abutment of the insertion part located at the top edge of the cover and the inner wall of the box body, this ensures good sealing between the four edges of the cover and the box body, effectively preventing oil fumes from entering the interior of the switch box.

[0017] In some embodiments, an insertion gap is formed between the support flange located at the two opposite side edges of the mounting port and the top edge of the mounting port, and the insertion part is inserted into the inner side of the box body through the insertion gap.

[0018] This design ensures that the insertion part located at the top edge of the lid can be smoothly inserted into the inside of the box body through the insertion gap.

[0019] In some embodiments, a first mounting hole is provided at the bottom edge and two opposite side edges of the lid, and a second mounting hole corresponding to the first mounting hole is provided on the supporting folded edge. The lid is fixed to the box body by fasteners passing through the first mounting hole and the second mounting hole.

[0020] This design utilizes fasteners to secure the lid to the box body, and the lid and box body are fixed by a three-sided screw method consisting of a top-side plug and a bottom-side and two opposite sides, effectively ensuring the stability of the lid and box body.

[0021] In some embodiments, the bottom edge of the lid has a bent portion that bends from the outer surface of the lid toward the inner surface, and the bent portion abuts against the support fold located at the bottom edge of the mounting opening.

[0022] This design ensures that the bottom edge of the cover effectively abuts against the supporting fold at the bottom edge of the mounting opening by setting a bend, thereby better preventing oil from entering the switch box.

[0023] In some embodiments, the bottom edge of the lid has an extension that extends away from the top edge of the lid and overlaps the outer surface of the box body in the area located at the bottom of the mounting opening.

[0024] This design ensures a tight seal between the bottom edge of the cover and the box body by providing an extension on the bottom edge of the cover. When oil fumes flow along the outer surface of the cover to the bottom edge of the cover, they will flow down along the extension instead of into the inside of the switch box, thus better preventing oil from entering the switch box.

[0025] In some embodiments, the extension is an extended folded edge formed by pressing the inner surface of the bottom edge of the lid toward the outer surface, and the outer surface of the box body located at the bottom side of the mounting opening is a plane, and the extended folded edge overlaps on the plane.

[0026] This design ensures that when the cover is installed at the mounting opening of the box body, the extended fold at the bottom edge of the cover smoothly overlaps the outer surface of the box body located at the bottom side of the mounting opening, and the extended fold fits against the outer surface of the box body, achieving a good effect of preventing oil from entering the switch box.

[0027] In some embodiments, a sealing strip is provided between the inner surfaces of the bottom edge and the two opposite side edges of the lid and the corresponding support fold.

[0028] This design utilizes a sealing strip to ensure a tight seal between the cover and the body, thereby better preventing oil from entering the switch box. Attached Figure Description

[0050] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0052] In related technologies, the cover and body of the switch box of a range hood are typically fixed together using latches and screws. Two spaced-apart latches are located on the top edge of the cover, which are inserted into the inside of the body through the mounting opening. The cover and body are then secured together with screws. However, this design often results in gaps between the cover and body, particularly at the joint between the top edge of the cover and the body. These gaps allow cooking fumes to enter the switch box during operation, accumulating inside and causing the switch box to fail to meet installation requirements. Furthermore, it can lead to malfunctions or corrosion of components such as the switch board inside the switch box.

[0053] Based on this, this application provides a range hood that has an insertion part extending from one end of the top edge of the cover to the other end. The insertion part is inserted into the inside of the box body through the installation port and overlaps and fits against the inner wall of the box body, ensuring the sealing of the top edge of the cover and the box body and avoiding gaps between the top edge of the cover and the box body, thereby effectively preventing oil fumes from entering the interior of the switch box.

[0054] The following reference Figures 1 to 16 The range hood provided in the embodiments of this application will be described in detail.

[0055] Reference Figure 1 and Figure 2 As shown, some embodiments of this application provide a range hood, including: a range hood body 1, a panel 2, and a switch box 3. The panel 2 is rotatably mounted on the range hood body 1; the switch box 3 is disposed on the inner surface of the panel 2, and the switch box 3 includes a box body 31 and a box cover 32. The box body 31 has an installation opening 311, and the box cover 32 is installed at the installation opening 311.

[0056] Specifically, refer to Figure 1 As shown, the main body 1 of the range hood may include a housing 11 and a smoke collection hood 12. A smoke exhaust channel is formed on the housing 11. The smoke collection hood 12 is connected to the lower part of the housing 11 and has a smoke collection chamber and an air inlet 121 communicating with the smoke collection chamber. The smoke collection chamber is connected to the smoke exhaust channel. The panel 2 is rotatably mounted on the smoke collection hood 12 to close or open the air inlet 121. When the range hood is needed, the control panel 2 can be rotated relative to the smoke collection hood 12 to open the air inlet 121, allowing the cooking fumes to be drawn into the smoke collection chamber through the air inlet 121 and then discharged through the smoke exhaust channel. When the range hood is not needed, the control panel 2 can be rotated in the opposite direction relative to the smoke collection hood 12 to close the air inlet 121, preventing the air inlet 121 from being exposed to the kitchen environment.

[0057] Reference Figure 2 and Figure 3 As shown, the switch box 3 is located on the inner surface of the panel 2, which is the surface of the panel 2 facing the air inlet 121, and also the surface of the panel 2 facing away from the exterior. The switch box 3 includes a box body 31 and a cover 32. The box body 31 has a receiving cavity for accommodating components such as the switch board. The box body 31 is connected to the inner surface of the panel 2. A mounting opening 311 communicating with the receiving cavity is opened on the side surface of the box body 31 away from the panel 2. The cover 32 is detachably installed at the mounting opening 311 to cover the mounting opening 311 and to facilitate the removal of the cover 32 for maintenance of the switch board and other components inside the switch box 3.

[0058] Among them, reference Figures 3 to 5 As shown, the top edge of the lid 32 is provided with a plug-in portion 321. The plug-in portion 321 extends from one end of the top edge of the lid 32 to the other end. The plug-in portion 321 is inserted into the inner side of the box body 31 through the mounting port 311 and abuts against and fits against the inner wall surface of the box body 31.

[0059] For example, refer to Figure 3 As shown in the diagram, the double-headed arrows XX indicate the width direction of the lid 32. The lid 32 has two opposite edges along the width direction, and the insertion portion 321 extends from one end of the top edge of the lid 32 to the other end. That is, the insertion portion 321 extends from one opposite edge of the lid 32 along the width direction to the other opposite edge. In other words, the width of the insertion portion 321 along the width direction of the lid 32 is equal to or approximately equal to the width of the lid 32.

[0060] In this way, the plug-in part 321 is inserted into the inner side of the box body 31 through the mounting port 311 and abuts against the inner wall surface of the box body 31. This makes the top edge of the box cover 32 form a relatively closed fit with the top edge of the mounting port 311 along the entire width direction of the box cover 32. This avoids gaps between the top edge of the box cover 32 and the box body 31 as much as possible, thereby effectively preventing oil fumes from entering the interior of the switch box 3, avoiding oil accumulation inside the switch box 3, meeting safety requirements, and preventing oil stains from accumulating on components such as the switch board inside the switch box 3, which could lead to failure or corrosion, thus extending the service life of components such as the switch board inside the switch box 3.

[0061] In some embodiments, refer to Figures 3 to 9 As shown, the insertion part 321 is an insertion folded edge formed by pressing the outer surface of the top edge of the cover 32 toward the inner surface. The area of ​​the box body 31 located on the top side of the mounting port 311 is a flat area, and the insertion folded edge is inserted into the inner side of the flat area.

[0062] In other words, the insert fold is pressed and folded towards the inner surface of the main body of the box cover 32 relative to the outer surface of the main body, so that a pressing step is formed between the insert fold and the main body of the box cover 32, a height difference is formed between the outer surface of the insert fold and the outer surface of the main body of the box cover 32, and the outer surface of the insert fold is set to sink relative to the outer surface of the main body of the box cover 32. This design ensures that the folded edge can be smoothly inserted into the inner side of the box 31 through the mounting port 311 on the box 31, and fits against the inner wall of the flat area on the top side of the mounting port 311 on the box 31, improving the convenience of inserting the folded edge on the cover 32 into the box 31; and by setting the area on the top side of the mounting port 311 of the box 31 as a flat area, after the cover 32 and the box 31 are assembled, the outer surface of the cover 32 exposed on the outside of the box 31 (that is, the outer surface of the main body of the cover 32) is flush or approximately flush with the outer surface of the box 31 around the mounting port 311, ensuring that the switch box 3 has a good appearance.

[0063] In other embodiments, reference is made to Figures 10 to 16 As shown, the insertion part 321 is an insertion fold formed by pressing the outer surface of the top edge of the cover 32 toward the inner surface. The area of ​​the box body 31 located on the top side of the mounting port 311 has a raised insertion groove 312, and the insertion fold is inserted into the inner side of the insertion groove 312.

[0064] The difference between this embodiment and the above embodiment is that the area on the top side of the mounting port 311 of the box body 31 is not a flat area. The area on the top side of the mounting port 311 of the box body 31 has a raised insertion groove 312. This is designed so that the insertion fold can be smoothly inserted into the inside of the box body 31, improving the convenience of the insertion fold on the box cover 32 and the box body 31.

[0065] In specific implementation, refer to Figure 13 and Figure 14 As shown, the insertion groove 312 is formed in the top side area of ​​the mounting opening 311. The insertion groove 312 can be formed by protruding from the inner surface of the box body 31 toward the outer surface. Specifically, it can be formed by the inner surface of the area on the top side of the mounting opening 311 of the box body 31 protruding toward the outer surface. The width of the insertion groove 312 can be equal to or approximately equal to the width of the top edge of the mounting opening 311, and the width of the insertion groove 312 is slightly larger than the width of the insertion flange. The insertion groove 312 can have a slot facing the bottom side area of ​​the mounting opening 311. The insertion flange is smoothly inserted into the inner side of the box body 31 through the slot of the insertion groove 312 and abuts against and fits against the inner wall surface of the box body 31.

[0066] In some embodiments, refer to Figures 3 to 9 As shown, the bottom edge and two opposite side edges of the mounting opening 311 are respectively formed with support flanges 313 extending toward the inner perimeter area of ​​the mounting opening 311. The bottom edge and two opposite side edges of the cover 32 are respectively supported at the corresponding support flanges 313 and are in contact with the support flanges 313.

[0067] For example, refer to Figure 3 As shown in the figure, the double-headed arrow XX indicates the width direction of the lid 32. The lid 32 has two opposite side edges along the width direction. The insertion part 321 extends from one opposite side edge of the lid 32 along the width direction to the other opposite side edge. The insertion part 321 is inserted into the inside of the box body 31 through the mounting port 311. The bottom edge of the lid 32 and the two opposite side edges are respectively supported on the corresponding support folds 313 on the box body 31 and are in contact with the support folds 313.

[0068] This configuration utilizes the three-sided support flanges 313 located at the bottom edge and two opposite side edges of the mounting port 311 to effectively support the cover 32. Furthermore, the bottom edge and two opposite side edges of the cover 32 are respectively fitted with the corresponding support flanges 313 to ensure the sealing between the bottom edge and the two opposite side edges of the cover 32 and the box body 31. Combined with the abutment and fit between the insertion part 321 located at the top edge of the cover 32 and the inner wall surface of the box body 31, good sealing is ensured between the four edges of the cover 32 and the box body 31, thereby effectively preventing oil fumes from entering the interior of the switch box 3.

[0069] In specific implementation, refer to Figure 4 , Figure 6 and Figure 7As shown, the supporting flange 313 can be formed by pressing the outer surface of the box body 31 around the mounting opening 311 toward the inner surface of the box body 31. That is, the supporting flange 313 is pressed toward the inner surface of the box body 31 relative to the outer surface of the box body 31 around the mounting opening 311, so that a pressing step is formed between the supporting flange 313 and the outer surface of the box body 31 around the mounting opening 311, and a height difference is formed between the outer surface of the supporting flange 313 and the outer surface of the box body 31 around the mounting opening 311. With this configuration, after the box cover 32 is assembled with the box body 31, the outer surface of the box cover 32 exposed on the outside of the box body 31 (that is, the outer surface of the main body of the box cover 32) is flush or approximately flush with the outer surface of the box body 31 around the mounting opening 311, so as to ensure that the switch box 3 has a good appearance.

[0070] It should be noted that the support flange 313 located at the bottom edge of the mounting port 311 can be connected to the support flanges 313 located at the two opposite side edges of the mounting port 311. This arrangement ensures the support strength of the box body 31 to the box cover 32 and achieves a good sealing effect, minimizing the possibility of oil fumes entering the interior of the switch box 3.

[0071] To ensure that the insertion part 321 located at the top edge of the lid 32 is smoothly inserted into the inside of the box body 31, refer to Figure 6 and Figure 7 As shown, an insertion gap 315 is formed between the support flange 313 located at the two opposite side edges of the mounting opening 311 and the top edge of the mounting opening 311, and the insertion part 321 is inserted into the inner side of the box body 31 through the insertion gap 315.

[0072] In specific implementation, the width of the insertion gap 315 can be slightly larger than the thickness of the insertion part 321 to ensure that the insertion part 321 is smoothly inserted into the inside of the box 31 through the insertion gap 315. However, it should not be too large, so as to avoid the insertion gap 315 being too large and causing the insertion part 321 to not properly cover the insertion gap 315, resulting in oil entering the switch box 3 through the uncovered insertion gap 315.

[0073] In some embodiments, the bottom edge and two opposite side edges of the cover 32 are respectively provided with first mounting holes 322, and the support fold 313 is provided with second mounting holes 314 corresponding to the first mounting holes 322. The cover 32 is fixed to the box body 31 by fasteners passing through the first mounting holes 322 and the second mounting holes 314.

[0074] This configuration allows for the use of fasteners to secure the lid 32 to the body 31. Furthermore, the lid 32 and body 31 are secured by a three-sided screw method: top-side insertion and bottom-side and two opposite sides. This effectively ensures the stability of the lid 32 and body 31.

[0075] In practice, fasteners can be screws or other fastening components. The number of fasteners can be set appropriately according to needs. For example, refer to... Figures 6 to 9 As shown, the fasteners are screws, and there are four screws. The bottom edge of the cover 32 is fixed to the corresponding support fold 313 by two spaced screws, and the two opposite side edges of the cover 32 are fixed to the corresponding support fold 313 by one screw.

[0076] To enhance the stability of the screw fastening between the lid 32 and the body 31, at least a portion of the first mounting hole 322 can be countersunk, and correspondingly, at least a portion of the second mounting hole 314 is a countersunk hole adapted to the shape of the first mounting hole 322. For example, refer to... Figures 6 to 9 As shown, the first mounting hole 322 located at the two opposite edges of the lid 32 is a countersunk hole, and correspondingly, the second mounting hole 314 opened on the support flange 313 at the two opposite side edges of the mounting opening 311 of the box body 31 is a countersunk hole.

[0077] In some embodiments, refer to Figures 3 to 9 As shown, the bottom edge of the lid 32 has a bent portion 323 that bends from the outer surface of the lid 32 toward the inner surface, and the bent portion 323 abuts against the support flange 313 located at the bottom edge of the mounting opening 311.

[0078] With this configuration, compared to the flat structure of the bottom edge of the cover 32, by providing a bent part 323 on the bottom edge of the cover 32, it is ensured that the bottom edge of the cover 32 effectively abuts and fits against the support fold 313 located at the bottom edge of the mounting opening 311, thereby achieving the purpose of better preventing oil from entering the switch box 3.

[0079] In other embodiments, reference is made to Figures 10 to 16 As shown, the bottom edge of the lid 32 is provided with an extension 324. The extension 324 extends away from the top edge of the lid 32 relative to the lid 32. The extension 324 overlaps the outer surface of the area of ​​the box body 31 located on the bottom side of the mounting opening 311.

[0080] The difference between this embodiment and the previous embodiment is that the bottom edge of the cover 32 does not have a bent portion 323. Instead, an extension portion 324 is provided at the bottom edge of the cover 32, extending away from the top edge of the cover 32. This arrangement ensures the seal between the bottom edge of the cover 32 and the cover 31 by overlapping the outer surface of the area on the bottom side of the mounting opening 311 of the box body 31 with the extension portion 324. When oil fumes flow along the outer surface of the cover 32 to the bottom edge of the cover 32, they will flow down along the extension portion 324 and will not flow into the interior of the switch box 3, thereby achieving better protection against oil entering the switch box 3.

[0081] Reference Figure 11 , Figure 15 and Figure 16 As shown, the extension 324 is an extended folded edge formed by pressing the inner surface of the bottom edge of the lid 32 toward the outer surface. The outer surface of the box body 31 located on the bottom side of the mounting opening 311 is a plane, and the extended folded edge overlaps on the plane.

[0082] In other words, the extended fold is pressed against the outer surface of the main body of the cover 32 relative to the inner surface of the main body, forming a pressing step between the extended fold and the main body of the cover 32. A height difference is formed between the outer surface of the extended fold and the outer surface of the main body of the cover 32, and the outer surface of the extended fold protrudes beyond the outer surface of the main body of the cover 32. This arrangement ensures that when the cover 32 is installed at the mounting opening 311 of the box body 31, the extended fold at the bottom edge of the cover 32 smoothly overlaps the outer surface of the box body 31 located at the bottom side of the mounting opening 311. Furthermore, by making the outer surface of the box body 31 located at the bottom side of the mounting opening 311 flat, the extended fold fits snugly against the outer surface of the box body 31, achieving a good effect of preventing oil from entering the switch box 3.

[0083] In practice, to avoid oil accumulation at the bottom edge of the lid 32, the extended fold at the bottom edge of the lid 32 can be smoothly connected to the main body of the lid 32 with rounded corners. In this way, when the oil fumes flow along the outer surface of the lid 32 to the bottom edge of the lid 32, they can flow along the rounded corners to the extended fold and flow down along the extended fold.

[0084] To better prevent oil from entering the switch box 3, in some embodiments, a sealing strip is provided between the inner surface of the bottom edge and the two opposite side edges of the cover 32 and the corresponding supporting flange 313. This arrangement ensures a tight seal between the cover 32 and the box body 31, thereby achieving a better effect of preventing oil from entering the switch box 3.

[0085] In specific implementations, a sealing strip can also be provided between the insertion part 321 of the lid 32 and the inner wall surface of the box body 31, so as to better ensure the sealing between the top edge of the lid 32 and the box body 31.
