Abstract
Description
Technical Field
[0001] This invention relates to range hoods, and more particularly to a decorative panel assembly and a range hood equipped with the decorative panel assembly. Background Technology
[0002] Range hoods have become an indispensable kitchen appliance in modern homes. They operate on the principles of fluid dynamics, using a centrifugal fan inside to draw in cooking fumes and a filter to remove some grease particles. The centrifugal fan consists of a casing, an impeller housed within the casing, and a motor that drives the impeller. As the impeller rotates, a negative pressure is generated at the center of the fan, drawing in the cooking fumes from below. After being accelerated by the fan, the fumes are collected by the casing and guided outdoors.
[0003] Currently, various low-suction range hoods have been disclosed in the prior art, such as the "Near-Suction Range Hood" disclosed in Chinese Invention Patent No. 201410537477.3 (Authorization Announcement No. CN 104329708 B). The panel of this range hood includes an upper panel and a lower panel, and a flip-up smoke baffle is installed on the panel. When the range hood is working, the smoke baffle flips upward to open the smoke inlet. In order to avoid interference between the upper chamfer of the smoke baffle and the upper panel when the smoke baffle is open, resulting in hard compression, which could cause the upper panel or the smoke baffle to crack due to large local concentrated stress, thereby causing product failure and even injury to the user, a gap is left between the upper part of the smoke baffle and the upper panel when the smoke baffle is open. The existence of this gap affects the appearance of the range hood and allows oil fumes to escape from the gap, resulting in poor smoke extraction effect. Summary of the Invention
[0004] The first technical problem to be solved by the present invention is to provide a decorative panel assembly with an adaptive floating structure, in view of the above-mentioned existing technology.
[0005] The second technical problem to be solved by the present invention is a range hood that can avoid interference between the smoke baffle and the decorative panel when the smoke baffle is opened and avoid the formation of gaps between the two.
[0006] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a decorative panel assembly, comprising a decorative panel, characterized in that it further comprises:
[0007] The panel bracket is a fixed bracket.
[0008] The support plate is fixed to the panel bracket.
[0009] A decorative panel bracket is located on the outside of a support plate, and the decorative panel is located on the outside of the decorative panel bracket and fixed to the decorative panel bracket.
[0010] An elastic element is provided between the support plate and the decorative panel bracket, and it keeps the decorative panel bracket tending to move outward.
[0011] The limiting component is fixed on the decorative panel bracket and can move synchronously with the decorative panel bracket, thereby limiting the movement of the decorative panel.
[0012] To ensure the overall appearance of the machine and to ensure that the smoke baffle can open smoothly, there are two limiting members, which are respectively fixed on the left and right sides of the decorative panel bracket. The limiting members have a limiting structure for limiting the movement of the decorative panel in the vertical direction and the parallel direction of the decorative panel.
[0013] The limiting component can have various installation structures. Preferably, the support plate has limiting holes on both the left and right sides, and the decorative panel bracket has its left and right sides bent inward to form bent pieces. The bent pieces pass through the corresponding limiting holes and are fixed to the limiting component.
[0014] In a further preferred embodiment, the limiting member is disposed on the outside of the bent piece and fixed on the bent piece.
[0015] The limiting member can have various structures. Preferably, the limiting member has a square base plate. The four edges of the square base plate are bent forward to form a first fold, a second fold, a third fold, and a fourth fold, respectively. The edge of the fourth fold is then folded inward to form a fifth fold. The fourth fold is fixed on the bent piece of the decorative panel bracket. The portion of the support plate located outside the limiting hole forms a stop portion. The stop portion extends into the interior of the limiting member and is used to abut against the first fold, the second fold, the third fold, and the fifth fold.
[0016] In order to make the limiting member and the support plate more reliably limit each other, the edge of the stop portion has an inward flange, the inward flange abuts against the second folded edge, and the extension direction of the inward flange is opposite to the extension direction of the second folded edge.
[0017] To facilitate the installation and guidance of the limiting component and reduce the resistance when the decorative panel bracket moves under force, the edge of the inner flange has a guide fold, which extends from the side where the second fold is located to the side where the fourth fold is located.
[0018] To make the installation structure of the support plate and decorative panel bracket more reasonable, the front side of the panel bracket has a concave cavity, the support plate is disposed in the cavity and fixedly connected to the panel bracket, and the decorative panel bracket is disposed in the cavity.
[0019] The elastic element can have various structures. Preferably, the elastic element is a compression spring, which is always in a compressed state. The inner end of the compression spring is fixed on the support plate, and the outer end of the compression spring abuts against the decorative panel bracket.
[0020] As a preferred embodiment of any of the above solutions, a first cushioning member is fixed to the outer side of the decorative panel. The first cushioning member can typically be a rubber pad.
[0021] Preferably, second buffer members are fixed on the left and right sides of the inner side of the decorative panel. The second buffer members can be made of compressible foam or the like, and can expand and contract with the movement of the decorative panel assembly, ensuring the exquisite appearance of both sides of the decorative panel.
[0022] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: a range hood, including an upper housing and a smoke collection chamber disposed at the bottom of the upper housing, wherein a smoke inlet is opened at the bottom of the smoke collection chamber, and a smoke baffle for opening and closing the smoke inlet is installed at the bottom of the smoke collection chamber, characterized in that: the decorative panel assembly is installed at the bottom of the smoke collection chamber and in front of the smoke inlet.
[0023] Further optimization involves the following: When the smoke baffle is open, its upper end abuts against the first buffer member. The decorative panel moves inward under the force of the smoke baffle, further compressing the elastic member. When the smoke baffle is closed, the decorative panel returns to its original position under the elastic force of the elastic member, making its outer surface flush with the outer surface of the smoke baffle. This structure offers several advantages. First, when the smoke baffle is open, the force applied to its upper end allows the decorative panel to move, preventing hard compression against the upper chamfer of the smoke baffle. This avoids localized stress concentration caused by hard compression, which could lead to glass breakage. The rubber pad prevents hard contact between the upper chamfer of the smoke baffle and the decorative panel, and ensures good contact between the upper edge of the smoke baffle and the decorative panel, preventing gaps and ensuring no smoke escapes from gaps when the range hood is operating. Second, when the smoke baffle is closed, the decorative panel assembly returns to its initial position under the force of the spring and the panel's own weight, maintaining the aesthetic appearance of the range hood when it is not in operation.
[0024] Further preferably, second buffer members are fixed on the left and right sides of the inner side of the decorative panel. When the smoke baffle is closed, the second buffer members are pressed between the bottom of the smoke hood and the decorative panel. The second buffer members are preferably made of compressible foam, which can expand and contract with the movement of the decorative panel assembly, ensuring the appearance of the two sides of the decorative panel.
[0025] Compared with existing designs, the advantages of this invention are as follows: the decorative panel assembly has a support plate fixed on the panel bracket, the decorative panel bracket is located on the outside of the support plate, the elastic member between the support plate and the decorative panel bracket keeps the decorative panel bracket moving outward, and the limiting member installed on the decorative panel bracket can limit the movement of the decorative panel. The range hood using this decorative panel assembly can ensure that the smoke baffle is flush with the decorative panel when closed, ensuring the exquisite appearance, and can also ensure that the upper part of the smoke baffle is completely in contact with the decorative panel when the smoke baffle is open, with no gap between the smoke baffle and the decorative panel, thereby preventing the oil fumes from escaping from between the smoke baffle and the decorative panel and ensuring the smoke extraction effect.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0038] like Figures 1 to 3 As shown, the decorative panel assembly of this embodiment includes a decorative panel 1, a panel support 2, a support plate 3, a decorative panel bracket 4, an elastic element 5, and a limiting element 6. The panel support 2 is a fixed support, with a recessed cavity 21 on its front side. The support plate 3 is disposed within the cavity 21 and fixedly connected to the panel support 2. The decorative panel bracket 4 is disposed within the cavity 21 and located outside the support plate 3. The elastic element 5 is disposed between the support plate 3 and the decorative panel bracket 4, and maintains the decorative panel bracket 4's tendency to move outward. The decorative panel 1 is disposed outside the decorative panel bracket 4 and fixed to it, and moves synchronously with the decorative panel bracket 4. The limiting element 6 is fixed to the decorative panel bracket 4 and can move synchronously with it, limiting the movement of the decorative panel 1.
[0039] In this embodiment, there are two limiting members 6, which are fixed to the left and right sides of the decorative panel bracket 4, respectively. Limiting holes 31 are opened on the left and right sides of the support plate 3. The left and right sides of the decorative panel bracket 4 are bent inward to form bent pieces 41, which pass through the corresponding limiting holes 31. The limiting members 6 are located on the outside of the bent pieces 41 and fixed to them with screws. Thus, the limiting members 6 and the decorative panel bracket 4 are connected and fixed to each other to ensure that they can move synchronously.
[0040] like Figures 4 to 6As shown, the limiting member 6 has a limiting structure for limiting the movement of the decorative panel 1 in the vertical direction and the parallel direction of the decorative panel 1. The limiting member 6 has a square base plate 60, the four edges of which are bent forward to form a first folded edge 61, a second folded edge 62, a third folded edge 63 and a fourth folded edge 64 respectively. The edge of the fourth folded edge 64 is then folded inward to the limiting member 6 to form a fifth folded edge 65. The fourth folded edge 64 is fixed to the bent piece 41 of the decorative panel bracket 4. The portion of the support plate 3 located outside the limiting hole 31 forms a stop portion 32. The stop portion 32 extends into the interior of the limiting member 6 and is used to abut against the first folded edge 61, the second folded edge 62, the third folded edge 63 and the fifth folded edge 65. The fifth fold 65 can limit the decorative panel 1 in the vertical direction, ensuring that the outer surface of the decorative panel 1 and the outer surface of the smoke baffle 10 are in the same plane when the smoke baffle 10 is closed, thus ensuring the overall appearance of the machine and preventing the decorative panel 1 from shifting downwards due to gravity. The second fold 62 limits the decorative panel 1 to the left and right. The first fold 61 and the third fold 63 limit the decorative panel 1 in the direction parallel to the decorative panel 1, preventing the component of gravity in this direction from causing the decorative panel 1 to shift downwards in this direction. This avoids the gap between the upper edge of the smoke baffle 10 and the lower edge of the decorative panel 1 being too small when the smoke baffle 10 is closed, and thus avoids interference between the upper edge of the smoke baffle 10 and the lower edge of the decorative panel 1 when the smoke baffle 10 is open. It can be seen that the folds of the limiting member 6 can achieve the limiting function in three different directions.
[0041] To make the limiting structure between the limiting member 6 and the support plate 3 more reliable, the edge of the stop portion 32 has an inwardly turned flange 33, which abuts against the second folded edge 62, and the extending direction of the inwardly turned flange 33 is opposite to the extending direction of the second folded edge 62. In addition, the edge of the inwardly turned flange 33 has a guide flange 34, which extends from the side where the second folded edge 62 is located to the side where the fourth folded edge 64 is located. The guide flange 34 facilitates the installation guidance of the limiting member 6 and reduces the resistance when the decorative panel bracket 4 moves under force.
[0042] like Figure 7 and Figure 8 As shown, the elastic element 5 in this embodiment is a compression spring. The inner end of the compression spring is fixed on the support plate 3, and the outer end of the compression spring abuts against the decorative panel bracket 4. The compression spring is always in a compressed state, that is, the compression spring always maintains a forward movement tendency on the decorative panel bracket 4.
[0043] In this embodiment, the decorative panel 1 is a glass decorative panel, and a first buffer 71 is fixed to the outer side of the decorative panel 1. The first buffer 71 is a rubber pad that is pasted on the outer surface of the decorative panel 1. Second buffers 72 are fixed to the left and right sides of the inner side of the decorative panel 1. The second buffers 72 are compressible foam that is pasted on.
[0044] like Figures 9 to 11 As shown, the range hood in this embodiment includes an upper housing 8 and a smoke collection chamber 9 located at the bottom of the upper housing 8. A smoke inlet 91 is opened at the bottom of the smoke collection chamber 9, and a baffle plate 10 for opening and closing the smoke inlet 91 is installed at the bottom of the smoke collection chamber 9. A decorative panel assembly is installed at the bottom of the smoke collection chamber 9 and in front of the smoke inlet 91. When the baffle plate 10 is opened, the decorative panel 1 can move slowly under the force applied to the upper end of the baffle plate 10, avoiding hard compression with the upper chamfer of the baffle plate 10. The first buffer 71, i.e., the rubber pad, can prevent hard contact between the upper chamfer of the baffle plate 10 and the decorative panel 1, and can ensure good contact between the upper edge of the baffle plate 10 and the decorative panel 1, avoiding gaps and ensuring that fumes do not escape from gaps when the range hood is working. At this time, the elastic member 5 is further compressed. Furthermore, the decorative panel assembly also prevents the rubber pad from being subjected to hard pressure from the upper edge of the smoke baffle 10 when it is fully open, thus extending the service life of the rubber pad. When the smoke baffle 10 is closed, under the action of the spring force of the elastic element 5 (compression spring) and the weight of the decorative panel 1 itself, the decorative panel assembly returns to its initial position, and the outer surface of the decorative panel 1 is flush with the outer surface of the smoke baffle 10. The second buffer 72 compressible foam is pressed between the bottom of the smoke hood and the decorative panel 1. The compressible foam expands and contracts with the movement of the decorative panel assembly, ensuring the appearance of the range hood when it is not in operation.
[0045] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
