Description

Technical Field

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

[0002] Range hoods, widely used kitchen appliances, primarily function to collect and exhaust cooking fumes. However, after prolonged use, grease inevitably accumulates inside, requiring cleaning, which has always been a challenge in product design. Currently, in addition to designs that are easy to clean and require no cleaning, the ease of disassembly of the range hood structure is also gradually becoming an important research and development direction.

[0003] In this structure, the range hood includes a housing and a lower panel. An air inlet is located on the housing, and the lower panel is installed below the air inlet. To facilitate cleaning, the lower panel is usually openable. During installation, the lower panel is first engaged with hooks on the panel bracket and hanging posts on the side wall of the housing, and then secured with screws passing through the panel bracket and the side wall of the housing. However, this method requires the screwdriver to be turned from the side during assembly and disassembly, which can easily interfere with the lower panel or other components such as the grille. This is not only inconvenient to operate but also poses a risk of structural damage. Utility Model Content

[0004] Therefore, it is necessary to provide a range hood that solves the problem of inconvenient disassembly and assembly of the lower panel of existing range hoods.

[0005] This application provides a range hood, which includes a housing, an oil guide plate, and a lower panel assembly. The oil guide plate is installed inside the housing, and an air inlet is provided on the front side of the housing. The lower panel assembly is located below the air inlet and includes a panel bracket and a lower panel. The panel bracket includes a bracket body, a mounting plate, and an extension plate. The lower panel is installed on the bracket body, and the mounting plate is connected to one side of the bracket body in the height direction and extends at least partially toward the oil guide plate. The extension plate is attached to the oil guide plate and connected to the mounting plate. A first connecting hole is provided on the extension plate, and a second connecting hole is provided on the oil guide plate. The range hood also includes fasteners that pass through and connect the first connecting hole and the second connecting hole. Along the thickness direction of the lower panel, the projection of the first connecting hole on the plane of the lower panel is offset from the lower panel.

[0006] In one embodiment, the mounting plate includes a first plate and a second plate, with the bracket body and the second plate respectively connected to the two sides of the first plate and arranged at an angle to the bracket body and the second plate; wherein, the extension plate is connected to the end of the second plate and extends to the end of the first plate, and the first plate, the second plate and the extension plate form a tapered structure.

[0007] In one embodiment, the included angle between the first plate and the second plate is A, and 95°≤A≤115°.

[0008] In one embodiment, the mounting plate further includes a third plate body connected to the side of the second plate body away from the first plate body and extending rearward and downward relative to the second plate body.

[0009] In one embodiment, the second plate and the third plate are connected by a circular arc transition.

[0010] In one embodiment, the housing is provided with a side plate, which is located on the side of the oil guide plate away from the extension plate and is fitted to the oil guide plate; a third connecting hole is provided on the side plate, and the fastener passes through and connects the first connecting hole, the second connecting hole and the third connecting hole.

[0011] In one embodiment, the range hood further includes a grille plate installed at the air inlet and located on the front side of the extension plate.

[0012] In one embodiment, the bottom of the grating plate abuts against the first plate body, and the bottom of the grating plate is provided with a support leg. A slot is provided at the connection between the first plate body and the second plate body, and the support leg extends into the slot.

[0013] In one embodiment, the shortest distance from the inner wall of the slot on the first plate to the support leg is B, and B≤2mm.

[0014] In one embodiment, the length of the support leg is L, the width of the support leg is W, and L / W≥8; and / or, the height of the support leg is H, and H≤5mm; and / or, the edge corner of the support leg on the side away from the grid plate is set as a rounded corner, and the radius of the rounded corner R≥H / 2.

[0015] Compared to existing technologies, the range hood provided in this application, by setting an mounting plate and an extension plate, allows for adjustment of the angle of the extension plate relative to the mounting plate, enabling the extension plate to fit against the inclined surface of the oil guide plate, thereby increasing the contact area between the two and effectively improving the connection strength. Furthermore, because the projection of the first connecting hole on the plane of the lower panel is offset from the lower panel itself—that is, the position of the first connecting hole extends beyond the upper edge of the lower panel—the probability of interference between the fastener and the lower panel during tightening is effectively reduced, significantly improving the ease of fastener assembly and disassembly. Simultaneously, compared to the traditional lateral installation method perpendicular to the sidewall of the housing, the angle formed between the installation direction of the fastener and the corresponding sidewall of the housing is smaller, further reducing the probability of interference with other structures, resulting in higher safety and simpler, faster assembly and disassembly.

[0035] Range hoods, widely used kitchen appliances, primarily function to collect and exhaust cooking fumes. However, after prolonged use, grease inevitably accumulates inside, requiring cleaning, which has always been a challenge in product design. Currently, in addition to designs that are easy to clean and require no cleaning, the ease of disassembly of the range hood structure is also gradually becoming an important research and development direction.

[0036] In this structure, the range hood includes a housing and a lower panel. An air inlet is located on the housing, and the lower panel is installed below the air inlet. To facilitate cleaning, the lower panel is usually openable. During installation, the lower panel is first engaged with hooks on the panel bracket and hanging posts on the side wall of the housing, and then secured with screws passing through the panel bracket and the side wall of the housing. However, this method requires the screwdriver to be turned from the side during assembly and disassembly, which can easily interfere with the lower panel or other components such as the grille. This is not only inconvenient to operate but also poses a risk of structural damage.

[0037] See also Figures 1-11 To address the inconvenience of disassembling and assembling the lower panel of existing range hoods, this application provides a range hood 100. The range hood 100 includes a housing 10, an oil guide plate 20, a grille plate 50, a smoke baffle plate 60, and a lower panel assembly 30. The oil guide plate 20 is installed inside the housing 10. An air inlet 11 is provided on the front side of the housing 10. The grille plate 50 is installed at the air inlet 11. The lower panel assembly 30 is located below the air inlet 11. The smoke baffle plate 60 is located in front of the grille plate 50 and is rotatably mounted on the housing 10 to open and close the air inlet 11. When the smoke baffle plate 60 is closed, it is flush with the lower panel assembly 30.

[0038] Specifically, if Figure 2 As shown, the outer periphery of the oil guide plate 20 is connected to the inner wall of the housing 10, and the oil guide plate 20 is basically tapered towards the inside of the housing 10 from the outer periphery to the center, so as to play a guiding role.

[0039] like Figures 2-6 As shown, the lower panel assembly 30 includes a panel bracket 31 and a lower panel 32. The panel bracket 31 can be a sheet metal part, and the lower panel 32 can be a glass part. Further, the panel bracket 31 includes a bracket body 311, a mounting plate 312, and an extension plate 313. The lower panel 32 is mounted on the bracket body 311, for example, by adhesive such as silicone sealant. The mounting plate 312 is connected to one side of the bracket body 311 in the height direction and extends at least partially towards the direction close to the oil guide plate 20. The extension plate 313 is attached to the oil guide plate 20 and connected to the mounting plate 312. The extension plate 313 has a first connecting hole 3131, and the oil guide plate 20 has a second connecting hole 21. The range hood 100 also includes a fastener 40, which passes through and connects the first connecting hole 3131 and the second connecting hole 21. Wherein, as... Figure 4 As shown, along the thickness direction of the lower panel 32, the projection of the first connecting hole 3131 on the plane where the lower panel 32 is located is offset from the lower panel 32.

[0040] It is understood that by setting the mounting plate 312 and the extension plate 313, the angle of the extension plate 313 relative to the mounting plate 312 can be adjusted accordingly, so that the extension plate 313 can fit against the inclined surface of the oil guide plate 20, thereby increasing the contact area between the two and effectively improving the connection strength. Furthermore, since the projection of the first connecting hole 3131 on the plane of the lower panel 32 is offset from the lower panel 32, that is, the position of the first connecting hole 3131 extends beyond the upper edge of the lower panel 32, the probability of the fastener 40 interfering with the lower panel 32 during the locking process can be effectively reduced, thereby significantly improving the convenience of fastener 40 during installation and removal. At the same time, compared with the traditional lateral installation method perpendicular to the side wall of the housing 10, the angle formed between the installation direction of the fastener 40 and the corresponding side wall of the housing 10 is smaller, which can further reduce the probability of interference with other structures, resulting in higher safety and simpler and faster installation and removal.

[0041] Furthermore, such as Figure 7 and Figure 10As shown, the housing 10 is provided with a side plate 12, which is located on the side of the oil guide plate 20 opposite to the extension plate 313 and is fitted to the oil guide plate 20. A third connecting hole 121 is provided on the side plate 12, through which a fastener 40 passes and connects the first connecting hole 3131, the second connecting hole 21, and the third connecting hole 121. That is, by connecting with the fastener 40 in one step, the lower panel assembly 30, the oil guide plate 20, and the housing 10 can be fixed simultaneously. This not only improves connection efficiency but also further increases the connection strength between the lower panel assembly 30 and the housing 10.

[0042] In one embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the mounting plate 312 includes a first plate body 3121 and a second plate body 3122. The first plate body 3121 is connected to the support body 311 and the second plate body 3122 on both sides, forming an angle with the support body 311 and the second plate body 3122. An extension plate 313 is connected to the end of the second plate body 3122 and extends to the end of the first plate body 3121. The first plate body 3121, the second plate body 3122, and the extension plate 313 form a conical structure. Thus, the conical triangular stabilizing area formed by the first plate body 3121, the second plate body 3122, and the extension plate 313 effectively improves the structural strength of the panel support 31, reduces the probability of deformation of the panel support 31 under external forces, and thus avoids damage during transportation.

[0043] Of course, in other embodiments, the extension plate 313 may also be connected to the end of the first plate 3121 and extend to the end of the second plate 3122, thereby forming a triangular stable region.

[0044] Furthermore, such as Figure 6 , Figure 8 and Figure 9 As shown, the mounting plate 312 also includes a third plate 3123, which is connected to the side of the second plate 3122 away from the first plate 3121 and extends rearward and downward relative to the second plate 3122. That is, the third plate 3123 and the second plate 3122 cooperate to form an air guide section to better guide the airflow direction during the operation of the range hood 100, thereby improving the overall performance of the machine.

[0045] To further enhance airflow performance, in one embodiment, the second plate 3122 and the third plate 3123 are connected by a circular arc transition, which can guide the airflow more smoothly. The radius of the arc between the second plate 3122 and the third plate 3123 can be set between 2mm and 3mm to form a large circular arc transition, further facilitating the guidance of airflow to the fan inlet 11. This also facilitates cleaning and disassembly, preventing users from encountering sharp edges of the sheet metal during routine cleaning and disassembly, thus enhancing safety.

[0046] For example, the radius of the arc between the second plate 3122 and the third plate 3123 can be set to 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm or 3mm, etc., which will not be listed here.

[0047] In the traditional structure, since the fastener 40 is installed laterally on the housing 10, when the user disassembles or installs the grating plate 50, they need to go around the lower panel 32 and the fastener 40, which is difficult and prone to errors that could damage the structure. Moreover, the fastener 40 is exposed in front of the grating plate 50, affecting the appearance of the structure. In this application, however, the fastener 40 is connected to the oil guide plate 20, which is closer to the inside of the housing 10. Therefore, the grating plate 50 can be directly installed on the front side of the extension plate 313, making installation simpler and allowing the extension plate 313 to be covered, preventing the extension plate 313 or the fastener 40 from being exposed and affecting the aesthetics.

[0048] Meanwhile, during installation, the bottom of the grating plate 50 provided in this application can abut against the first plate 3121 and be guided and positioned by the second plate 3122, thereby further improving the assembly efficiency of the grating plate 50.

[0049] Specifically, the included angle between the first plate 3121 and the second plate 3122 is A, and 95°≤A≤115°. It is easy to understand that when A>115°, the tilt angle of the second plate 3122 relative to the first plate 3121 is too large, which is not conducive to the positioning of the grating plate 50 using the second plate 3122. Furthermore, since the extension plate 313 is connected to the end of the second plate 3122, an excessively large tilt angle of the second plate 3122 relative to the first plate 3121 will increase the area of ​​the extension plate 313, making it visible through the grating plate 50 and affecting aesthetics. When A<95°, the risk of interference between the grating plate 50 and the second plate 3122 during installation increases, which is not conducive to the assembly of the grating plate 50. Simultaneously, it will result in an excessively small area of ​​the extension plate 313, which is not conducive to the setting of the first connecting hole 3131 and increases the processing difficulty.

[0050] Preferably, the value of A can be set to 110°, but it is not limited to this. The value of A can also be 95°, 100°, 105° or 115°, etc., which will not be listed here.

[0051] In one embodiment, such as Figure 9 and Figure 11 As shown, the bottom of the grating plate 50 is provided with a support foot 51, and the connection between the first plate body 3121 and the second plate body 3122 is provided with a slot 314. The support foot 51 extends into the slot 314. In this way, the positioning effect between the grating plate 50 and the panel support 31 can be further improved, ensuring the stability of the position of the grating plate 50.

[0052] To further improve the installation stability of the grating plate 50, the shortest distance from the inner side wall of the slot 314 on the first plate 3121 to the support leg 51 is B, and B≤2mm. This helps to reduce the shaking of the grating plate 50.

[0053] For example, the value of B can be 2mm, 1.8mm, or 1.6mm, etc.

[0054] Furthermore, in one embodiment, the length of the support leg 51 is L, the width of the support leg 51 is W, and L / W ≥ 8. That is, the support leg 51 is a flat and wide strip, which can reduce the probability that the support leg 51 will scratch the panel support 31 during the installation of the grille plate 50, thereby ensuring the reliability of the structure. For example, the value of L / W can be 8, 9, or 10, etc.

[0055] In one embodiment, the height of the support leg 51 is H, and H ≤ 5mm. Similarly, by limiting the height of the support leg 51, the probability of the support leg 51 contacting and scratching the panel bracket 31 can be further reduced. The value of H can be 5mm, 4.5mm, or 4mm, etc.

[0056] In one embodiment, the edge corner of the support leg 51 on the side away from the grille plate 50 is set as a rounded corner, and the radius of the rounded corner R ≥ H / 2. It is easy to understand that by setting the edge corner of the support leg 51 as a rounded corner and setting R ≥ H / 2, the probability of the support leg 51 scratching the panel bracket 31 can be further reduced.

[0057] The range hood 100 of this application can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the range hood 100 to perform corresponding operations, thereby realizing intelligent control of the range hood 100 and improving the user experience.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
