Description

Technical Field

[0001] The utility model generally relates to the field of kitchen appliances, and in particular to a decorative cover and a range hood. Background Art

[0002] The decorative cover of the range hood is used to cover the air hood and air duct on the top of the range hood, and plays a role in aesthetics and decoration. The decorative cover can usually be pulled out from the top of the range hood, and the height can be adjusted according to the height of the user's house. Most European range hoods have a main decorative cover and an additional decorative cover on the outside of the main body shell. The double-layer decorative cover is more expensive; and some main decorative covers have no space or the space is too small between the main decorative cover and the main body shell, so the additional decorative cover cannot be installed, or it is difficult to pull out the additional decorative cover, and the surface is easily scratched during the pulling process.

[0003] Generally, there are hanging ears on both sides of the top of the attached decorative cover, and there are screw holes on the hanging ears. The attached decorative cover is fixed to the ceiling by screws. When installing the attached decorative cover, you need to hang the whole machine first, and then pull out the attached decorative cover. The installation master needs to hold the hanging ears with his hands to prevent the attached decorative cover from slipping, and then aim at the ceiling to screw in, which is inconvenient to install. And when installing the attached decorative cover, if the ceiling strength is poor, such as plastic ceiling, the attached decorative cover cannot be stably fixed on the ceiling, which poses a safety hazard. Therefore, there are situations where the attached decorative cover is difficult to install, and the installation requires a certain strength of the ceiling. Utility Model Content

[0042] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] Please refer to Figure 1 and Figure 8 As shown, this embodiment provides a decorative cover, including:

[0045] A first decorative cover 10;

[0046] a fixing bracket 20, the fixing bracket 20 being mounted at one end of the first decorative cover 10, and being used to support the first decorative cover 10 and be mounted to the ceiling together with the first decorative cover 10;

[0047] The second decorative cover 30 is disposed at one end of the first decorative cover 10 away from the fixing bracket 20 and is installed at the periphery of the air duct 70 to surround the air duct 70 .

[0048] The decorative cover provided in this embodiment provides two decorative covers. The second decorative cover 30 is a main decorative cover, which is installed on the air duct 70 to wrap the air duct 70. The first decorative cover 20 is installed at one end of the main decorative cover as an additional decorative cover. The first decorative cover 10 is directly used as an outer shell panel, and the outer shell panel can be eliminated to reduce costs. The first decorative cover 20 is installed on the ceiling through a fixing bracket 20, which is more convenient to install, and the first decorative cover 20 is supported and fixed more firmly and reliably.

[0049] The decorative cover structure provided in this embodiment includes two parts, namely, a first decorative cover 10 and a second decorative cover 30 which are arranged up and down (the direction is taken as an example of the position during the installation process). The second decorative cover 30 is arranged on the periphery of the air duct 70 to wrap and fix the air duct 70. The second decorative cover 30 is used as both the main body shell and the decorative cover outside the main body, which has lower cost. The first decorative cover 10 is arranged on the periphery of the second decorative cover 30, which is slightly larger than the second decorative cover 30 and can wrap the second decorative cover 30. When installing, the first decorative cover 10 is slid and adjusted according to the distance between the second decorative cover 30 and the ceiling to adapt to installation spaces of different heights. The first decorative cover 10 and the second decorative cover 30 provided in this embodiment have similar structures, both of which are formed by three baffles in the shape of a Chinese character, and semi-enclose the air duct 70 from the front end and both sides, providing a relatively flat and beautiful outer surface;

[0050] The first decorative cover 10 is arranged around the air duct 70, and the lower part of the air duct 70 is connected to the smoke hood 40 for collecting oil smoke. The air duct 70 and the smoke hood 40 are connected by a connecting plate 80, so that the air duct 70 can be fixed to the smoke hood 40 through the connecting plate 80, and the air duct 70 is not easy to generate vibration and abnormal noise when in use. The connecting plate 80 is provided with two arc mounting surfaces 81, and the two arc mounting surfaces 81 are hollow. The arc mounting surface 81 is used to achieve fixation with the bottom of the air duct 70, and the curvature of the arc mounting surface 81 matches the curvature of the air duct 70, and is evenly attached to the bottom of the air duct 70, so that the gravity of the air duct 70 itself is evenly dispersed to the connecting plate 80, thereby improving the strength of the whole machine and reducing the vibration and abnormal noise generated when the range hood is in operation; at the same time, the connecting plate 80 is connected to the air duct 70, which can play a certain role in collecting and guiding oil, and reduce the risk of oil dripping.

[0051] The connecting plate 80 is a hollow structure with an oil hole at the bottom, through which the collected waste oil leaks into the oil cup. A mounting hole is also provided to achieve a fixed connection with the smoke hood 40, which can replace the outer shell enclosure for connection and fixation. Canceling the outer shell enclosure can further reduce the cost of the range hood.

[0052] The decorative cover provided in this embodiment semi-encloses the air duct 70 through the second decorative cover 30, and the side of the air duct 70 close to the wall is provided with an outer shell back plate 60, and the air duct 70 is fixedly installed on the outer shell back plate 60, wherein the second decorative cover 30 is provided with a flange structure on the side close to the outer shell back plate 60, and the flange structure is provided with a mounting hole for realizing the fixation between the second decorative cover 30 and the outer shell back plate 60.

[0053] Further, one end of the first decorative cover 10 away from the second decorative cover 30 is provided with a relatively arranged first flanging 11 and a relatively arranged first hanging ear 12. The first flanging 11 is arranged towards the inside of the first decorative cover 10, and the first hanging ear 12 is arranged towards the outside of the first decorative cover 10;

[0054] The fixing bracket 20 is provided with a relatively arranged second flanging 21 and a relatively arranged second hanging ear 22. Both the second flanging 21 and the second hanging ear 22 are arranged towards the outside of the first decorative cover 10. The first flanging 11 and the second flanging 21 are in abutting cooperation, and the first hanging ear 12 and the second hanging ear 22 are used for installing with the suspended ceiling.

[0055] In this embodiment, the first decorative cover 10 is fixed to the suspended ceiling through the fixing bracket 20. When the first decorative cover 10 is installed, a first flanging 11 and a first hanging ear 12 are arranged at one end close to the suspended ceiling. The first hanging ear 12 is a structure protruding from the decorative cover. A through hole is provided on the first hanging ear 12 to fix the first decorative cover 10 to the suspended ceiling. The first hanging ear 12 protrudes towards the outside of the first decorative cover 10 for easy installation; the first flanging 11 is bent towards the inside of the first decorative cover 10 to form a structure as shown in Figure 2 As shown. There is a notch between the first flangings 11 at each side position of the first decorative cover 10 for the second hanging ear 22 on the fixing bracket 20 to pass through; the fixing bracket 20 is fixedly installed with the first decorative cover 10. The fixing bracket 20 also has a three-sided structure in the shape of a C. When installed, the two opposite sides cooperate with the two opposite sides of the first decorative cover 10. Second flangings 21 and second hanging ears 22 are provided on the two sides. The second hanging ear 22 passes through the notch between the above-mentioned first flangings 11 and coincides with the first hanging ear 12, and is fixed to the installed suspended ceiling through screws. The second flanging 21 is arranged towards the outside of the first decorative cover 10 to form a structure as shown in Figure 3 As shown. After the first decorative cover 10 and the fixing bracket 20 are installed, the first flanging 11 and the second flanging 21 are in abutting contact for supporting and fixing to form a form as shown in Figure 4 As shown. The length of the second flanging 21 can be the same as or slightly shorter than the length of the first flanging 11.

[0056] Further, the second hanging ear 22 is arranged higher than the second flanging 21.

[0057] Reference Figure 3As shown in the figure, the height of the second hanging ear 22 provided on the fixed bracket 20 is higher than that of the second flanging 21. Preferably, a stepped surface is provided on the second flanging 21, and the second hanging ear 22 is located on the stepped surface, so that the second hanging ear 22 is higher than the first hanging ear 12. The second hanging ear 22 is located above the first hanging ear 12, and the first flanging 11 is placed above the second flanging 21, so that the first decorative cover 10 and the fixed bracket 20 are respectively subjected to mutual acting forces, and the fixing method is more stable and reliable, reducing the risk of installation falling off. Moreover, in this embodiment, the second hanging ear 22 is a stepped structure relative to the second flanging 21. The second hanging ear 22 is used to cooperate with the first hanging ear 12, and can be abutted or have a certain gap to fix the first decorative cover 10 on the ceiling. During the installation and cooperation process, in order to enable the second hanging ear 22 to achieve stable installation with the first decorative cover 10 and avoid the plane of the first hanging ear 12, preferably, the bottom surface of the second hanging ear 22, that is, the surface close to the first decorative cover 10, is parallel to the surface where the first flanging 11 on the first decorative cover 10 is located.

[0058] Furthermore, the fixed bracket 20 further includes an installation surface 24, and the installation surface 24 is located on the side of the first decorative cover 10 with an opening, and a fixed bracket hanging hole 23 is provided on the installation surface 24.

[0059] In this embodiment, the fixed bracket 20 is also provided with an installation surface 24. The installation surface 24 is located at the opening of the first decorative cover 10, that is, the back of the entire decorative cover installation. This installation surface 24 generally contacts the wall surface. A fixed bracket hanging hole 23 is provided on the installation surface 24, and the fixed bracket 20 is fixed on the wall surface through the fixed bracket hanging hole 23, which is convenient for the installation of the entire decorative cover.

[0060] In this embodiment, the first decorative cover 10 is installed and fixed through the fixed bracket 20. First, the fixed bracket 20 can be pre-hung on the wall through the fixed bracket hanging hole 23 and an external hook, and then the first decorative cover 10 is pulled, so that the first decorative cover 10 reaches the set installation height, and the first flanging 11 of the first decorative cover 10 is moved and placed above the second flanging 21 of the fixed bracket 20. Since the first decorative cover 10 is a U-shaped structure, the opposite side surfaces have a certain deformation ability. By pulling the position of the first decorative cover 10 close to the installation ceiling, the first flanging 11 is moved above the second flanging 21. At this time, the first decorative cover 10 will not slide off, and the installer does not need to hold the first decorative cover 10 by hand, greatly reducing the installation difficulty; and through the fixed bracket 20, the mutual fixation with the first decorative cover 10 is realized, and it can be installed in places with weak installation ceiling strength, such as a plastic ceiling, without affecting the fixation of the range hood. The entire range hood is installed more stably and has stronger safety.

[0061] Furthermore, gaps 90 are provided between both ends of the mounting surface 24 and the first decorative cover 10 , and the distance between the mounting surface 24 and the first decorative cover 10 is adjustable.

[0069] like Figure 6As shown, the limit block 50 includes a limit body 51, which is provided with a penetrating mounting hole 52, and is detachably mounted on the outer shell back plate 60 behind the air duct 70 through the mounting hole 52; a hanging groove 53 is provided at one end of the limit block 50, and is clamped on the outer shell back plate 60 through the hanging groove 53. The hanging groove 53 is preferably set in the form of a U-shaped groove, and is clamped on the outer shell back plate 60 through the hanging groove 53, and is moved to the position where it needs to be fixed and installed, so that the mounting hole on the limit block 50 is fixed to the corresponding screw hole on the outer shell back plate 60, and there is no need to manually hold the limit block 50, so the installation is convenient.

[0070] Furthermore, slide grooves 54 are provided on both sides of the limiting body 51 , and the openings of the slide grooves 54 are arranged toward the second decorative cover 30 . The slide grooves 54 extend along the length direction of the limiting body 51 , and the slide grooves 54 are slidably connected to the first decorative cover 10 .

[0071] In this embodiment, the limit block 50 is preferably set to a long strip structure, the hanging groove 53 is set on the short side of the limit body, and the slide grooves 54 are set on both sides. The opening of the slide groove 54 is facing the hanging groove 53, that is, the opening of the slide groove 54 is set toward the position of the first decorative cover 10 and the second decorative cover 30. When the first decorative cover 10 is set outside the second decorative cover 30, part of the structure on the first decorative cover 10 is inserted into the slide groove 54, forming a Figure 7 The form shown limits the freedom of the lower end of the first decorative cover 10, and the upper end of the first decorative cover 10 can still undergo a certain deformation to facilitate its installation and fixation. This setting allows the first decorative cover 10 to move back and forth only along the length direction of the slide groove 54, which facilitates the installation of the first decorative cover 10; preferably, the slide groove 54 is set in the form of a U-shaped groove, and the depth of the slide groove 54 is related to the width of the corresponding flange 14 on the first decorative cover 10.

[0072] Furthermore, the first decorative cover 10 is provided with a relative third flange 13 , and the third flange 13 is arranged on an edge adjacent to the first flange 11 .
