Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically, it relates to a range hood. Background Technology

[0002] Range hoods have become an essential household appliance in the kitchen, and as people's living standards continue to improve, consumers are also placing higher demands on the appearance and shape of range hoods.

[0003] Currently, glass panels are commonly used for the panel components of range hoods. Glass panels have the advantages of being aesthetically pleasing and easy to clean, which not only meets consumers' demand for the aesthetics of range hoods, but also makes it convenient for consumers to clean and maintain the range hoods. Consumers can directly clean the outer surface of the glass panel, or they can remove the glass panel to clean the inside of the cabinet.

[0004] The applicant's previous technical solution disclosed a range hood that achieves a fixed connection between a glass panel, a control panel, and a smoke collection chamber. The range hood includes a glass panel, a control panel, and a smoke collection chamber, and further includes a first bracket fixedly connected to the glass panel, a second bracket fixedly connected to the control panel, and a third bracket fixedly connected to the smoke collection chamber. The third bracket has at least two mounting parts, which are respectively fixedly connected to the first and second brackets, so that the glass panel, control panel, and smoke collection chamber are tightly assembled together, reducing installation gaps. However, fixing the glass panel and smoke collection chamber requires at least two types of brackets, and to maintain the stability of the assembly structure, at least two of each type of bracket are symmetrically arranged. This not only results in high production costs but also requires pre-fixing the brackets on the glass panel and smoke collection chamber, leading to low assembly efficiency.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a range hood to reduce production costs and improve assembly efficiency.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A range hood includes a smoke collection chamber and a glass panel mounted on the smoke collection chamber. The smoke collection chamber has an installation hole. The glass panel is mounted on a bracket. The bracket is inserted into the installation hole from a first direction and forms an interference fit with the wall of the installation hole.

[0009] Furthermore, the bracket includes a bracket body and a support leg protruding from the bracket body in a first direction. The bracket body is fixedly attached to the glass panel, and the support leg is inserted into the mounting hole in the first direction and forms an interference fit with the wall of the mounting hole.

[0010] Preferably, the support leg is a flexible support leg;

[0011] More preferably, the support leg is a flexible support leg made of stainless steel.

[0012] Furthermore, the support body is provided with at least two legs, which are respectively located on both sides of the axis of the support body;

[0013] Preferably, the two legs are symmetrically arranged on both sides of the axis of the support body.

[0014] Furthermore, the radial dimension of the bracket body is larger than the radial dimension of the mounting hole, and the bracket body is matched with the smoke collection chamber on the outer periphery of the mounting hole.

[0015] Furthermore, the support leg includes a first inclined portion formed by bending and extending from the support body in a first direction. The first inclined portion has a first guide slope, which guides the first inclined portion to be inserted into the mounting hole in the first direction. The first guide slope abuts against the wall of the mounting hole.

[0016] Furthermore, the first guide slope extends away from the axis of the support body and bends in the first direction, with the angle between the first guide slope and the plane perpendicular to the first direction being less than 90°.

[0017] Furthermore, the support leg also includes a second inclined portion formed by bending the extended end of the first inclined portion in a first direction. The second inclined portion has a second guide slope. The second guide slope and the first guide slope respectively guide the second inclined portion and the first inclined portion to be inserted into the mounting hole in the first direction and to pass through the mounting hole. The second guide slope and the wall of the mounting hole form an interference fit.

[0018] Furthermore, the second guide slope extends close to the axis of the support body and bends towards the first direction, with the angle between the second guide slope and the plane perpendicular to the first direction being greater than 90°.

[0019] Furthermore, at least part of the mounting hole wall has an arc surface that matches the contour of the first guide slope and / or the second guide slope, and the arc surface protrudes in a direction close to the centerline of the mounting hole.

[0020] Furthermore, the extended ends of the first inclined portion and / or the extended ends of the second inclined portion bend and extend toward the axis of the bracket body to form a fixing portion. The fixing portion is arranged parallel to the bracket body, and the fastener passes through the connecting holes opened on the fixing portion and the bracket body in sequence.

[0021] Preferably, the fastener is a self-tapping screw;

[0022] More preferably, the bracket body includes a first wall and a second wall facing away from each other, with the second wall near the smoke collection chamber and the tail of the self-tapping screw abutting against the second wall.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] 1. In this invention, the bracket installed on the glass panel is inserted into the mounting hole from the first direction. The bracket undergoes elastic deformation and forms an interference fit with the wall of the mounting hole, so that the glass panel is fixed on the smoke collection chamber. The assembly structure of the glass panel and the bracket is simple and easy to operate, and the connection is strong. This not only improves the assembly efficiency of the range hood and reduces the labor intensity of workers, but also reduces the number of parts used and lowers the production cost of the range hood.

[0025] 2. In this invention, the fixing part is provided with a connecting hole for the self-tapping screw to pass through. The tail of the self-tapping screw abuts against the second wall surface of the bracket body, so that the elastic support foot has rigidity and is not easy to undergo elastic deformation under external force, thereby realizing the self-locking function.

[0026] 3. In this invention, if it is necessary to disassemble the glass panel to clean or repair the inside of the smoke collection chamber, simply remove the self-tapping screws first, and then squeeze the support legs to the opposite side so that the support legs are separated from the smoke collection chamber due to contraction, thus achieving the separation of the glass panel from the smoke collection chamber.

[0027] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] like Figures 1 to 8 As shown, this embodiment of the invention provides a range hood, including a smoke collection chamber 100 and a glass panel installed on the smoke collection chamber 100. The smoke collection chamber 100 has a mounting hole 111. The glass panel is installed on a bracket 200. The bracket 200 is inserted into the mounting hole 111 from a first direction and forms an interference fit with the hole wall of the mounting hole 111.

[0046] With the above-mentioned range hood, the bracket 200 installed on the glass panel and the mounting hole 111 opened on the smoke collection chamber 100 are interference-fitted, so that the glass panel and the smoke collection chamber 100 are tightly fixed together. The assembly structure is simple, the assembly efficiency is improved, the labor intensity of workers is reduced, the number of parts used is reduced, the production cost of the range hood is reduced, and the market competitiveness of the product is improved.

[0047] Example 1

[0048] like Figures 1 to 8 As shown, this embodiment of the invention provides a range hood. The bracket 200 includes a bracket body 21 and a support leg 22 protruding from the bracket body 21 in a first direction. The bracket body 21 is fixedly attached to the glass panel. The support leg 22 is inserted into the mounting hole 111 in the first direction and forms an interference fit with the hole wall of the mounting hole 111. Thus, a snap-fit ​​structure is formed between the support leg 22 and the hole wall of the mounting hole 111, realizing a firm connection between the glass panel and the smoke collection chamber 100.

[0049] Preferably, the support leg 22 is an elastic support leg 22. Under the action of external force, the support leg 22 undergoes elastic deformation and is inserted into the mounting hole 111. After the external force is removed, the support leg 22 returns to its original shape, and the surface of the support leg 22 fits seamlessly with the hole wall of the mounting hole 111. Thus, the support leg 22 and the hole wall of the mounting hole 111 form an interference fit, so that the glass panel and the smoke collection chamber 100 are tightly connected.

[0050] More preferably, the support leg 22 is an elastic support leg 22 made of stainless steel, and in particular, the support leg 22 made of stainless steel has good elasticity.

[0051] like Figure 3 and Figure 4 As shown, in this embodiment, the support body 21 is provided with at least two legs 22, and the two legs 22 are respectively arranged on both sides of the axis of the support body 21; preferably, the two legs 22 are symmetrically arranged on both sides of the axis of the support body 21.

[0052] In the above scheme, the bracket body 21 is provided with at least two legs 22, each leg 22 forming an interference fit with the wall of the mounting hole 111, which not only enhances the stability of the assembly structure of the glass panel and the smoke collection chamber 100, making the bracket 200 in a state of force balance, but also improves the assembly efficiency of the range hood, so that the legs 22 undergo elastic deformation under the pressure of external force, thereby inserting into the mounting hole 111.

[0053] like Figure 7 and Figure 8 As shown, in this embodiment, the radial dimension of the bracket body 21 is greater than the radial dimension of the mounting hole 111, and the bracket body 21 is matched with the smoke collection chamber 100 on the outer periphery of the mounting hole 111.

[0054] In the above scheme, the bracket body 21 is limited to the smoke collection chamber 100 on the outer periphery of the mounting hole 111, which plays a role in positioning and fixing. Under the premise that the support leg 22 is interference-fitted with the hole wall of the mounting hole 111, the connection between the bracket 200 and the smoke collection chamber 100 is more secure, and the glass panel is fixedly connected to the smoke collection chamber 100 through the bracket 200.

[0055] like Figure 4 and Figure 7 As shown, in this embodiment, the support leg 22 includes a first inclined portion 221 formed by bending and extending from the support body 21 in a first direction. The first inclined portion 221 has a first guide slope 2221, which guides the first inclined portion 221 to be inserted into the mounting hole 111 from the first direction. The first guide slope 2221 abuts against the hole wall of the mounting hole 111.

[0056] In the above scheme, the first guide slope 2221 guides the first inclined part 221 to be inserted into the mounting hole 111, which makes it easier for the workers performing the assembly operation to insert the support leg 22 into the mounting hole 111 more quickly and effortlessly. At the same time, after the external force is removed, the first inclined part 221 is tightly fitted with the hole wall of the mounting hole 111, thereby ensuring the stability of the connection between the bracket 200 and the smoke collection chamber 100.

[0057] like Figure 4 and Figure 7 As shown, in this embodiment, the first guide slope 2221 is away from the axis of the support body 21 and bends and extends in the first direction, and the angle between the first guide slope 2221 and the plane perpendicular to the first direction is less than 90°.

[0058] In the above scheme, the angle between the first guide slope 2221 and the plane perpendicular to the first direction is an acute angle. After removing the external force, the first guide slope 2221 is ensured to fit tightly with the hole wall of the mounting hole 111, reducing the installation gap, so as to achieve the purpose of tightly assembling the glass panel and the smoke collection chamber 100 together.

[0059] like Figure 4 and Figure 7 As shown, in this embodiment, the support leg 22 further includes a second inclined portion 222 formed by bending the extended end of the first inclined portion 221 in a first direction. The second inclined portion 222 has a second guide slope 2221. The second guide slope 2221 and the first guide slope 2221 respectively guide the second inclined portion 222 and the first inclined portion 221 to be inserted into the mounting hole 111 in the first direction and to pass through the mounting hole 111. The second guide slope 2221 forms an interference fit with the hole wall of the mounting hole 111.

[0060] In the above scheme, the support leg 22 undergoes elastic deformation under the action of external force. The second guide slope 2221 and the first guide slope 2221 guide the second inclined part 222 and the first inclined part 221 to be inserted into the mounting hole 111 from the first direction and pass out of the mounting hole 111. After the external force is removed, the bracket 200 returns to its original shape or the elastic deformation decreases. Since the second guide slope 2221 forms an interference fit with the hole wall of the mounting hole 111, the first guide slope 2221 abuts or has an interference fit with the hole wall of the mounting hole 111, thereby reducing the gap between the first guide slope 2221 and the hole wall of the mounting hole 111.

[0061] like Figure 4 and Figure 7 As shown, in this embodiment, the second guide slope 2221 is close to the axis of the support body 21 and bends and extends in the first direction, and the angle between the second guide slope 2221 and the plane perpendicular to the first direction is greater than 90°.

[0062] In the above scheme, the support leg 22 undergoes elastic deformation under the action of external force, so that the angle between the second guide slope 2221 and the plane perpendicular to the first direction is greater than 90°, which facilitates the second inclined part 222 to be quickly inserted into the mounting hole 111 from the first direction and to pass out of the mounting hole 111. Thus, after the external force disappears, the first guide surface and the hole wall of the mounting hole 111 are limited and matched, so as to realize the fixed connection between the glass panel and the smoke collection chamber 100.

[0063] like Figures 3 to 6 As shown, in this embodiment, at least a portion of the mounting hole 111 has an arc surface that matches the contour of the first guide slope 2221 and / or the second guide slope 2221, and the arc surface protrudes in a direction close to the center line of the mounting hole 111.

[0064] In the above scheme, the wall of the mounting hole 111 has an arc surface, which not only facilitates the first guide slope 2221 to guide the first inclined part 221 and / or the second guide slope 2221 to guide the second inclined part 222 to be inserted into the mounting hole 111, reducing the frictional resistance caused by the line-surface contact, but also facilitates the tight fit between the first guide surface and the wall of the mounting hole 111. In addition, it avoids the burrs on the outer periphery of the mounting hole 111 from scratching the bracket 200.

[0065] With the above-mentioned range hood, the support leg 22 and the wall of the mounting hole 111 are interference-fitted to form a snap-fit ​​structure, which tightly fixes the glass panel and the smoke collection chamber 100 together. The assembly structure is simple, improves assembly efficiency, reduces the labor intensity of workers, reduces the number of parts used, and lowers the production cost of the range hood.

[0066] Example 2

[0067] like Figure 8 As shown, this embodiment is a further limitation of the first embodiment described above. The extension end of the first inclined portion 221 and / or the extension end of the second inclined portion 222 bends and extends toward the axis of the bracket body 21 to form a fixing portion 223. The fixing portion 223 is arranged parallel to the bracket body 21. Fasteners pass through the fixing portion 223 and the connecting hole 2231 opened on the bracket body 21 in sequence. Preferably, the fastener is a self-tapping screw 300. More preferably, the bracket body 21 includes a first wall surface 211 and a second wall surface 212 facing away from each other. The second wall surface 212 is close to the side of the smoke collection chamber 100, and the tail of the self-tapping screw 300 abuts against the second wall surface 212.

[0068] In the above scheme, the fixing part 223 is provided with a connecting hole 2231 for the self-tapping screw 300 to pass through. The tail of the self-tapping screw 300 abuts against the second wall surface 212 of the bracket body 21, so that the elastic support leg 22 has rigidity and is not easy to undergo elastic deformation under external force, thereby realizing the self-locking function. If the glass panel is to be disassembled under necessary conditions, the self-tapping screw 300 needs to be removed first, and then the support leg 22 is squeezed to the opposite side. The support leg 22 separates from the smoke collection chamber 100 due to contraction, thereby realizing the separation of the glass panel from the smoke collection chamber 100.

[0069] Example 3

[0070] like Figures 1 to 8 As shown, this embodiment is a further limitation of the above embodiments one and two. The smoke collection chamber 100 has a front plate 11, and the front plate 11 has a mounting hole 111. The glass panel is mounted on the bracket 200. The bracket 200 is inserted into the mounting hole 111 from front to back and forms an interference fit with the hole wall of the mounting hole 111.

[0071] like Figure 4 and Figure 7As shown, in this embodiment, the support body 21 is provided with at least two legs 22, and the two legs 22 are respectively arranged on both sides of the axis of the support body 21; preferably, the two legs 22 are symmetrically arranged on both sides of the axis of the support body 21.

[0072] like Figure 4 and Figure 7 As shown, in this embodiment, the support leg 22 includes a first inclined portion 221 that extends backward from the support body 21 and a second inclined portion 222 that extends backward from the extension end of the first inclined portion 221. The first inclined portion 221 is integrally connected to the support body 21 and extends away from the axis of the support body 21. The extension end of the first inclined portion 221 is bent toward the axis of the support body 21 to form the second inclined portion 222.

[0073] like Figure 4 and Figure 7 As shown, in this embodiment, the first inclined portion 221 has a first guide slope 2221, and the second inclined portion 222 has a second guide slope 2221. The maximum vertical distance between the second guide slopes 2221 of the fixing portion 223, which is symmetrically arranged along the axis of the bracket body 21, is greater than the maximum radial dimension of the cross-section of the mounting hole 111. Specifically, under the action of external force, the second inclined portion 222 undergoes elastic deformation. The second guide slope 2221 guides the second inclined portion 222 to be inserted into the mounting hole 111 from front to back and to pass out of the mounting hole 111. The first guide slope 2221 guides the first inclined portion 221 to be inserted into the mounting hole 111 from front to back. After the external force is removed, the second inclined portion 222 returns to its original state, and the first guide slope 2221 abuts against the front plate flange 112. The second inclined portion 222 and the front plate flange 112 form an interference fit.

[0074] If the glass panel of the range hood described above needs to be disassembled for cleaning or maintenance of the smoke collection chamber 100, simply remove the self-tapping screws 300 first, then press the support leg 22 to the opposite side, causing the support leg 22 to contract and separate from the smoke collection chamber 100, thus separating the glass panel from the smoke collection chamber 100.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
