Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an air duct cover structure and a range hood. Background Art

[0002] Range hoods are usually equipped with a duct cover structure for covering the smoke outlet and the telescopic smoke duct. Since the range hood installation scenarios in different users' homes are different, the distance between the top plate of the range hood and the ceiling will also vary. For this reason, the duct cover structure usually includes a lower duct cover and an upper duct cover. The lower duct cover is installed on the top plate of the range hood, and the upper duct cover is movably installed on the inner side of the lower duct cover and can slide up and down relative to the lower duct cover. Therefore, according to the distance between the lower duct cover and the ceiling in the specific installation scenario, the upper duct cover can be pulled up to abut against the ceiling and installed on the ceiling.

[0003] However, since the cross-sectional shapes of the lower duct cover and the upper duct cover are usually U-shaped, the opposite side edges of the upper duct cover are easily deformed inward under the action of external force, and since the range hood shakes during operation, it is also easy to cause the upper duct cover to shake relative to the lower duct cover. For this reason, some manufacturers will set guide rail pairs on the opposite side inner walls of the main air duct to match the upper duct cover. Although this structure can limit the opposite side walls of the upper duct cover, thereby avoiding deformation of the opposite side walls of the upper duct cover and reducing the shaking between the upper duct cover and the lower duct cover, the guide rail pairs added to this structure make the structure of the duct cover structure more complicated, and the production and processing are more complicated and cumbersome, which not only reduces the production and processing efficiency of the duct cover structure, but also increases the production and processing cost of the duct cover structure.

[0042] Reference Figures 1 to 5 One embodiment of the utility model provides a duct cover structure, which includes a lower duct cover 100 and an upper duct cover 200. The lower duct cover 100 includes a first front plate 110 and first side plates 120 correspondingly connected to the opposite sides of the first front plate 110. The edge of one end of the first side plate 120 away from the first front plate 110 has a first folded edge 121 bent inwardly. The upper end of the first folded edge 121 is provided with a forward-bending limiting portion 122. The limiting portion 122 is spaced apart from the corresponding first front plate 110 and forms a limiting groove 123. The upper duct cover 200 is slidably installed on the inner side of the lower duct cover 100. The upper duct cover 200 includes a second front plate 210 and second side plates 220 correspondingly connected to the opposite sides of the second front plate 210. The end of the second side plate 220 away from the second front plate 210 is movably inserted into the corresponding limiting groove 123.

[0043] In the above structure, a first folded edge 121 is provided on an edge of a side of the first side panel 120 away from the first front panel 110, and a limiting portion 122 is bent at the upper end of the first folded edge 121, and a limiting groove 123 is formed between the limiting portion 122 and the first front panel 110. Thus, the upper air duct cover 200 can be movably installed in the lower air duct cover 100, and the second side panel 220 can be movably inserted into the corresponding limiting groove 123, so that the upper air duct cover 200 can be limited, which can not only reduce the shaking between the upper air duct cover 200 and the lower air duct cover 100, but also reduce the deformation of the two second side panels 220 of the upper air duct cover 200 under the action of external force. In addition, the structure only needs to bend the edge of the first side panel 120 to form the first folded edge 121, and bend the upper end of the first folded edge 121 to form the limiting portion 122. The structure is simple in structure and easy to process. It not only facilitates the improvement of the production and processing efficiency of the air duct cover structure, but also eliminates the need to set up other structures such as guide rail pairs, thereby greatly reducing the production and processing costs of the air duct cover structure.

[0044] Reference Figures 1 to 10 In some embodiments, the upper edge of the second side panel 220 is provided with a fourth folded edge 221 bent inwardly. When the upper air duct cover 200 moves relative to the lower air duct cover 100 toward the inside of the lower air duct cover 100, the fourth folded edge 221 can overlap the corresponding limiting portion 122.

[0045] In the above structure, by providing a fourth folded edge 221 on the upper edge of the second side plate 220 that can overlap with the limiting portion 122 , the upper duct cover 200 can be prevented from falling off from below the lower duct cover 100 .

[0046] Reference Figures 1 to 10 In some embodiments, a fourth flange 222 is provided on a side edge of the fourth folded edge 221 away from the corresponding second side plate 220 .

[0047] In the above structure, the setting of the fourth flange 222 can make the edge of the fourth folded edge 221 smoother, avoiding cutting or scratching the user due to the sharp edge of the fourth folded edge 221, thereby protecting the user.

[0048] It is understandable that, referring to Figures 1 to 10 The fourth flange 222 can be specifically formed by folding the edge of the fourth folded edge 221 downward by 180 degrees.

[0049] Reference Figure 1 and Figure 2In some embodiments, a mounting bracket 300 is further included. The mounting bracket 300 has a mounting portion 310 and a connecting portion 320. The mounting portion 310 is used to be mounted to a wall. The connecting portion 320 is connected to the mounting portion 310 and extends forward relative to the mounting portion 310. One of the second side panels 220 can be connected to the connecting portion 320.

[0050] In the prior art, the conventional installation method of the upper air duct cover 200 is to install a hook on the ceiling, and then pull the lower air duct cover 100 upward to the hook, but this method cannot make the upper end of the upper air duct cover 200 completely fit with the ceiling, and there will be a certain gap between the upper air duct cover 200 and the ceiling, which affects the overall aesthetics. To this end, by adopting the air duct cover structure of the embodiment of the utility model, the mounting bracket 300 has a mounting portion 310 and a connecting portion 320, and the mounting portion 310 can be directly installed on the wall, and the connecting portion 320 extends forward relative to the mounting portion 310, and can be connected with the second side plate 220 of the upper air duct cover 200, thereby facilitating the upper end of the upper air duct cover 200 to abut against the ceiling and be flush with the ceiling iron. In addition, the structure only needs to connect the second side plate 220 and the connecting portion 320 from the side, which is simple and convenient to operate, thereby facilitating the installation and assembly of the air duct cover structure.

[0051] Reference Figure 1 and Figure 2 In some embodiments, the connecting portion 320 is formed by bending one side edge of the mounting portion 310 forward.

[0052] In the above structure, the connection portion 320 is formed by bending one side edge of the mounting portion 310 forward, thereby making the structure of the mounting bracket 300 relatively simple, and only needs to be bent, which is convenient for the production and processing of the mounting bracket 300. In addition, the connection portion 320 is formed by bending the mounting portion 310, which can also increase the structural strength of the mounting bracket 300 and improve the installation stability when the upper duct cover 200 is installed on the mounting bracket 300.

[0053] In some embodiments, there are two connecting parts 320 , and the two connecting parts 320 can be connected to the two second side panels 220 in a one-to-one corresponding manner.

[0054] In the above structure, by providing two connecting parts 320 , both side panels of the upper air duct cover 200 can be connected with the corresponding connecting parts 320 , thereby greatly improving the installation stability of the upper air duct cover 200 .

[0055] It can be understood that the number of the above-mentioned connecting parts 320 is two, and specifically, two mounting brackets 300 can be set, and each mounting bracket 300 has a mounting part 310 and two connecting parts 320, or, one mounting bracket 300 can be set, and the mounting bracket 300 has a mounting part 310 and two connecting parts 320, and the two connecting parts 320 are both connected to the mounting part 310, thereby reducing the number of accessories that need to be installed and facilitating the installation of the mounting bracket 300.

[0056] Reference Figures 1 to 10 In some embodiments, the upper edge of the second front plate 210 is provided with a third folded edge 211 bent inwardly, and a third flange 212 is provided on a side edge of the third folded edge 211 away from the second front plate 210 .

[0057] In the above structure, by setting the third folded edge 211 and the third flange 212 on the upper edge of the second front panel 210, the structural strength of the upper air duct cover 200 can be improved, and the upper edge of the second front panel 210 can also be made smoother, thereby avoiding cutting or scratching the user due to the sharp upper edge of the second front panel 210 during the installation of the upper air duct cover 200, thereby protecting the user.

[0058] It is understandable that, referring to Figures 1 to 10 The third flange 212 can be specifically formed by folding the edge of the third fold 211 downward by 180 degrees.

[0059] Reference Figures 1 to 10 In some embodiments, the upper edge of the first front panel 110 is provided with a first flange 111 folded inwardly, and the upper edge of each first side panel 120 is provided with a second flange 124 folded inwardly.

[0060] In the above structure, by providing the first flange 111 and the second flange 124, the upper edge of the lower duct cover 100 can be made smoother, thereby preventing the user from being cut or scratched by the sharp upper edge of the upper duct cover 200 during the installation of the duct cover structure, thereby protecting the user.

[0061] It is understandable that, referring to Figures 1 to 10 The first flange 111 can be formed by folding the upper edge of the first front plate 110 downward by 180 degrees. Similarly, the second flange 124 can be formed by folding the upper edge of the first side plate 120 downward by 180 degrees.

[0062] Reference Figures 1 to 10 In some embodiments, the lower edge of each first side panel 120 is provided with a second folded edge 125 folded outward, and the second folded edge 125 is provided with at least one mounting hole 126 .

[0063] In the above structure, by providing the second folded edge 125 at the lower edge of the first side plate 120, and the second folded edge 125 is provided with at least one mounting hole 126, it is convenient to mount the lower duct cover 100 on the top plate 410 of the range hood body 400. Among them, since the second folded edge 125 is formed by folding outward relative to the first side plate 120, the second folded edge 125 is located outside the duct cover structure during installation, which is convenient for operators to operate, making the installation of the lower duct cover 100 more convenient and simple.

[0064] Reference Fig.11 An embodiment of the utility model further provides a range hood, which includes a range hood body 400 and an air duct cover structure of any of the above embodiments, wherein the lower end of the lower air duct cover 100 abuts against the top plate 410 of the range hood body 400 and is cooperatively connected with the top plate 410.

[0065] In the above structure, by adopting the duct cover structure of any of the above embodiments, the upper duct cover 200 can be movably installed in the lower duct cover 100, and the second side plate 220 can be movably inserted in the corresponding limiting groove 123, so that the upper duct cover 200 can be limited, which can not only reduce the shaking between the upper duct cover 200 and the lower duct cover 100 when the range hood is working, but also reduce the deformation of the two second side plates 220 of the upper duct cover 200 under the action of external force. And the duct cover structure only needs to bend the edge of the first side plate 120 to form the first folded edge 121, and bend the upper end of the first folded edge 121 to form the limiting portion 122, which has a simple structure and is easy to process, and can be convenient for the production and manufacture of the range hood.

[0066] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
