[0041] In order to better explain the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0042] It should be clear that, for the purpose, technical solutions and advantages of the embodiments of the present disclosure to be clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, not all embodiments. The components of the embodiments of the present disclosure generally described and illustrated in the accompanying drawings herein can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the claimed present disclosure, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present disclosure.

[0043] A specific embodiment is described below, in which:

[0044] First, as shown in Figure 1 and Figure 2 , a door panel structure applied to a range hood is provided, the door panel structure is rotatably mounted on the range hood, comprising:

[0045] a circuit board 1 in a shape of a circular ring (hui-shaped), with an LED strip 14 arranged on the outer periphery of the circuit board 1;

[0046] a glass mounting plate 2 in a shape of a circular ring (hui-shaped), wherein the glass mounting plate 2 is fixedly mounted below the circuit board 1;

[0047] a square functional development board 3, wherein the functional development board 3 can be used for mounting functional modules, the functional development board 3 is fixedly mounted below the circuit board 1 and arranged at the center position of the glass mounting plate 2, an annular channel 100 is formed between the functional development board 3 and the glass mounting plate 2, and the annular channel 100 serves as an illumination channel for the circuit board 1.

[0048] The door panel structure applied to a range hood in this embodiment realizes the integrated design of illumination and function expansion through a laminated structure with specific geometric shapes. The hui-shaped (circular ring-shaped) circuit board 1 refers to an annular light-emitting base body with a central hollow area, and this structure reserves an installation space for subsequent function expansion through the central hollow area. The glass mounting plate 2 adopts a geometric bearing structure with the same geometric shape as that of the circuit board 1. The functional development board 3 serves as a square bearing platform, and the annular spacing maintained between the functional development board 3 and the glass mounting plate 2 forms a continuous optical path channel.

[0049] The circular lighting track is achieved through the vertical stacking of three layers: a light panel 1, a glass mounting plate 2, and a functional development plate 3, with size adjustments. The outer contour of the glass mounting plate 2 is larger than that of the light panel 1, while the inner contour of the glass mounting plate 2 is smaller than that of the light panel 1. This ensures that the light panel 1 and the glass mounting plate 2 are aligned with the same central axis, allowing the light panel 1 to be stably placed on the glass mounting plate 2. The side length of the functional development plate 3 is larger than the inner contour of the light panel 1, resulting in a partial overlap between the functional development plate 3 and the light panel 1. This proportional relationship allows the glass mounting plate 2, the light panel 1, and the functional development plate 3 to combine and form a circular lighting track. While maintaining the circular lighting function, the originally unused central area in the center of the light panel 1 is transformed into a functional expansion area. This structural layout solves the problem of space waste in traditional structures.

[0050] In practical implementation, the functional development board 3 can carry a touch switch module, an air quality sensor, or a wireless communication unit. Its electrical connection with the external control system can be achieved through a flexible circuit board or wireless transmission. This modular design makes the door panel structure possible to be continuously upgraded.

[0051] In this embodiment, as Figure 2 and Figure 3 As shown, a plurality of first support frames 21 are provided on the glass mounting plate 2;

[0052] Multiple second support frames 31 are provided on the functional development board 3, and the second support frames 31 are aligned with the first support frames 21 one by one; the lamp board 1 is clamped and fixed in the horizontal direction by the multiple first support frames 21 and the multiple second support frames 31.

[0053] The steps of clamping and fixing multiple first support frames 21 and multiple second support frames 31 include: the first support frame 21 on the glass mounting plate 2 and the second support frame 31 on the functional development plate 3 form a one-to-one alignment layout, so that the lamp plate 1 is embedded between the two and positioned by the mechanical constraints of the first support frame 21 and the second support frame 31.

[0054] Specifically, such as Figure 3 The diagram illustrates the arrangement of the first support frame 21 and the second support frame 31. The first support frame 21 is positioned on the upper, lower, left, and right sides of the glass mounting plate 2, while the second support frame 31 is positioned at corresponding locations on the functional development plate 3. During installation, the lamp panel 1 is placed within the clamping space formed by the first support frame 21 and the second support frame 31. Furthermore, the symmetrical distribution design of the first support frame 21 and the second support frame 31 constrains the lamp panel 1 in the X, Y, and Z axes, reducing the occurrence of wobbling after installation.

[0055] In this embodiment, as Figure 2 As shown, a first pressure plate 211 is constructed on the first support frame 21, and the distance between the first pressure plate 211 and the glass mounting plate 2 is equivalent to the thickness of the lamp plate 1; a second pressure plate 311 is constructed on the second support frame 31, and the distance between the second pressure plate 311 and the functional development plate 3 is equivalent to the thickness of the lamp plate 1.

[0056] After the lamp panel 1, glass mounting plate 2 and functional development plate 3 are assembled and installed, the lamp panel 1 is vertically positioned by being clamped by the first pressure plate 211 and the glass mounting plate 2, and the lamp panel 1 is vertically positioned by being clamped by the second pressure plate 311 and the functional development plate 3.

[0057] Meanwhile, the lamp plate 1 supports the function development board 3 through the second pressure plate 311 and places the function development board 3 in the middle of the glass mounting plate 2 and below the lamp plate 1.

[0058] In practical applications, the first pressure plate 211 refers to the limiting structure set on the first support frame 21. The first pressure plate 211 is located in the middle of the first support frame 21. Its purpose is to constrain the vertical displacement of the lamp plate 1 by forming a precise limiting space with the glass mounting plate 2, thereby achieving vertical positioning of a local position of the lamp plate 1. Similarly, the second pressure plate 311 refers to the limiting structure set on the second support frame 31. The second pressure plate 311 is located in the middle of the second support frame 31. Its purpose is to constrain the vertical displacement of the lamp plate 1 by forming a precise limiting space with the functional development board 3, thereby achieving vertical positioning of a local position of the lamp plate 1. Based on the aforementioned vertical positioning method of the local position of the lamp plate 1, the overall vertical stable positioning of the lamp plate 1 is achieved.

[0059] The dimensions of the limiting space refer to the distance between the first pressing plate 211 and the glass mounting plate 2, and the distance between the second pressing plate 311 and the functional development plate 3, which strictly correspond to the thickness of the lamp plate 1.

[0060] Furthermore, when the lamp panel 1 is pressed in for installation, the limiting space formed by the first pressing plate 211 and the glass mounting plate 2 first constrains the lamp panel 1 in the vertical direction; such as Figure 2As shown, the functional development board 3 only contacts the lamp board 1 in the horizontal direction. Therefore, when the functional development board 3 is placed below the lamp board 1, the lamp board 1 needs to provide support. The lamp board 1 is first installed on the glass mounting plate 2 and is horizontally and vertically limited by the first support frame 21 and the first pressure plate 211 on the first support frame 21. At this time, there is contact pressure between the lamp board 1 and the glass mounting plate 2. After the functional development board 3 is installed below the lamp board 1, without any structural assistance on the functional development board 3, the functional development board 3 needs to rely on the lamp board 1 to provide a support base. The second support frame 31 and the second pressure plate 311 on the second support frame 31 serve as the connection structure between the functional development board 3 and the lamp board 1. While providing horizontal and vertical limitation between the functional development board 3 and the lamp board 1, the lamp board 1 supports the functional development board 3 through the second pressure plate 311, thereby allowing the functional development board 3 to be installed below the lamp board 1. At this time, there is contact pressure between the lamp board 1 and the second pressure plate 311 to achieve the supporting function.

[0061] To further improve the installation stability between the first support frame 21 and the lamp board 1 and between the second support frame 31 and the lamp board 1, in this embodiment, a first silicone strip 212 is provided between the first support frame 21 and the lamp board 1; and a second silicone strip 312 is provided between the second support frame 31 and the lamp board 1.

[0062] The first silicone strip 212 serves as an elastic buffer element between the first support frame 21 and the lamp panel 1, and the second silicone strip 312 serves as an elastic buffer element between the second support frame 31 and the lamp panel 1. Specifically, the first silicone strip 212 is clamped between the outer contour of the first support frame 21 and the lamp panel 1, and the second silicone strip 312 is clamped between the inner contour of the second support frame 31 and the lamp panel 1.

[0063] The first silicone strip 212 and the second silicone strip 312 are disposed in the installation gap between the first support frame 21 and the lamp board 1 and in the installation gap between the first support frame 21, thereby forming a barrier structure that can prevent external dust from entering.

[0064] In addition, the first silicone strip 212 and the second silicone strip 312 provide effective elastic pressure between the first support frame 21 and the lamp board 1 and between the second support frame 31 and the lamp board 1, thereby improving installation stability.

[0065] In this embodiment, as Figure 3 As shown, the lamp panel 1 includes:

[0066] A light guide plate 11 in the shape of a U-shape, with the LED light strip 14 arranged on the outer periphery of the light guide plate 11;

[0067] The light-emitting rubber plate 12 is in a shape of a hollow square, and the light-emitting rubber plate 12 is arranged above the light guide rubber plate 11;

[0068] The light-diffusing rubber plate 13 is in a shape of a hollow square, and the light-diffusing rubber plate 13 is arranged below the light guide rubber plate 11.

[0069] In some specific application examples, the light guide rubber plate 11 can be a polycarbonate plate, the light-emitting rubber plate 12 can be an acrylic plate with a matte paint sprayed on the surface thereof, the light-diffusing rubber plate 13 can be an acrylic plate containing titanium dioxide diffusion particles, and the light guide rubber plate 11, the light-emitting rubber plate 12 and the light-diffusing rubber plate 13 are fixed in a laminated manner; light emitted by the LED strip 14 on the outer periphery of the light guide rubber plate 11 is firstly primarily diffused by the material property of the light guide rubber plate 11 itself and guided to the annular region of the light guide rubber plate 11, the light-emitting rubber plate 12 performs secondary reflection through a diffuse reflection coating on the surface (e.g., matte paint), so that the brightness of light is enhanced in the vertical direction, and then the light passing through is refracted for a third time by diffusion particles (e.g., titanium dioxide diffusion particles) inside the light-diffusing rubber plate 13, thereby eliminating the phenomenon of local brightness concentration, and thus achieving a uniform light-emitting effect of the annular lighting channel.

[0070] In some of the foregoing embodiments of the present application, a structural form in which a glass mounting plate 2 and a function development plate 3 directly carry a light panel 1 is provided. However, the following problems exist in this process: when the glass mounting plate 2 and the function development plate 3 directly fix the light panel 1, an integral supporting structure is lacked, resulting in insufficient installation stability of the light panel 1; the spatial layout between the glass mounting plate 2 and the function development plate 3 does not form a clear mounting area, which may affect the cooperative assembly of the light panel 1 and a functional module; meanwhile, the rotational connection between the door panel structure and a range hood main body 300 lacks a stable installation reference, resulting in limitation of the overall structural strength.

[0071] In some of the foregoing embodiments, a structural form in which a glass mounting plate 2 and a function development plate 3 directly carry a light panel 1 is provided. However, the following problems exist in this process: when the glass mounting plate 2 and the function development plate 3 directly fix the light panel 1, an integral supporting structure is lacked, which may result in insufficient installation stability of the light panel 1; the spatial layout between the glass mounting plate 2 and the function development plate 3 does not form a clear mounting area, which may affect the cooperative assembly of the light panel 1 and a functional module; meanwhile, the rotational connection between the door panel structure and a range hood main body 300 lacks a stable installation reference, resulting in limitation of the overall structural strength.

[0072] Accordingly, the door panel structure is further improved. In this embodiment, as shown in Figure 1 and Figure 3 , the door panel structure further comprises: a fixing plate 4, the fixing plate 4 is connected and fixed to the glass mounting plate 2, and the fixing plate 4 is rotatably connected to a range hood.

[0073] The fixed plate 4 is used to construct the basic support frame of the door panel structure. The rotatable connection between the fixed plate 4 and the range hood can be achieved using a hinge structure. The purpose of introducing the fixed plate 4 is to ensure that the door panel structure has the basic functional requirement of opening and closing after being combined with the glass mounting plate 2 and rotatably connected by the fixed plate 4. In addition, the fixed plate 4 can also establish a unified installation benchmark, unifying the installation benchmarks of the scattered glass mounting plate 2, functional development plate 3 and light plate 1 onto the fixed plate 4, thereby improving the rigidity of the overall structure.

[0074] In this embodiment, preferably, the fixing plate 4 is square and the glass mounting plate 2 is U-shaped. The outer contour of the fixing plate 4 is similar to the outer contour of the glass mounting plate 2, so that the fixing plate 4 and the glass mounting plate 2 can be aligned and connected as a whole, making the structure aesthetically pleasing after the fixing plate 4 and the glass are installed and combined. In addition, the outer peripheral edge of the fixing plate 4 is folded down to form an L-shaped connecting part, and the fixing plate 4 is fixedly connected to the glass mounting plate 2 through the L-shaped connecting part.

[0075] After the fixing plate 4 and the glass mounting plate 2 are fixedly connected by the L-shaped connecting part, the fixing plate 4 and the glass mounting plate 2 are separated by the L-shaped fixing part to form an installation space, which is used to place the lamp plate 1.

[0076] The L-shaped connecting part refers to the vertical folded edge structure formed by extending the edge of the fixing plate 4 downwards. It can be achieved by bending or integral molding. The L-shaped connecting part increases the contact surface between the fixing plate 4 and the glass mounting plate 2 for fixed connection. The installation space refers to the interval and height provided by the L-shaped connecting part between the fixing plate 4 and the glass mounting plate 2, forming an interval area that is equivalent to the shape of the fixing plate 4 (such as square). This interval area provides a positioning area for the lamp panel 1 and reserves a hidden installation cavity for the functional module.

[0077] In this embodiment, as Figure 2 As shown above, the glass mounting plate 2 is provided with multiple first support frames 21, and the functional development plate 3 is provided with multiple second support frames 31. After the fixing plate 4 is installed, the upper ends of the multiple first support frames 21 are connected and fixed to the fixing plate 4, and the multiple second support frames 31 are connected and fixed to the fixing plate 4. Since the glass mounting plate 2 and the functional development plate 3 are directly connected to the fixing plate 4 through the first support frames 21 and the second support frames 31 respectively, the installation structure stability of the glass mounting plate 2 and the functional development plate 3 can be increased. This is suitable for the range hood door panel environment that needs to withstand long-term vibration and temperature changes, and can effectively maintain the accurate positioning and stable operation of each functional module.

[0078] It can also be understood that the contact pressure between the lamp plate 1 and the second pressure plate 311 of the second support frame 31, which has the function of supporting, has also been changed. After the functional development board 3 is connected and fixed on the fixed plate 4 through multiple second support frames 31, the lamp plate 1 is supported by the second support frame 31 and installed above the functional development board 3, thereby reducing the supporting pressure of the second support frame 31 (that is, it can work with the first support frame 21 to support the lamp plate 1), so that the installation position of the lamp plate 1 is more stable.

[0079] As a preferred method for adding functional modules in this embodiment, in this embodiment, such as Figure 2 As shown, a square opening 41 is provided in the middle of the fixed plate 4; a switch control box 200 for placing switch elements is installed at the square opening 41. The switch control box 200 is connected to the function development board 3 below, so that the functional module of the switch control box 200 with switch control function can be placed in a hidden mounting cavity and connected to the function development board 3.

[0080] Secondly, in this embodiment, as Figure 1 As shown, a range hood is provided, comprising:

[0081] The range hood body 300 has a hinge component located below it.

[0082] The range hood body 300 is connected to the door panel structure as described above via a hinge.

[0083] Because the range hood uses the door panel structure described above, it has all the beneficial effects of the door panel structure, which will not be elaborated here.

[0084] In summary, the door panel structure and range hood used in this embodiment, through the combined design of the U-shaped light panel 1 and the square functional development board 3, not only realizes the ring lighting channel but also reserves space for functional expansion, providing the possibility of adding a large number of functional modules to the range hood in the future, which is beneficial for users / developers to expand the functions.

[0085] Finally, it should be noted that the above-described embodiments are merely specific implementations of this disclosure, used to illustrate the technical solutions of this disclosure, and not to limit them. The protection scope of this disclosure is not limited thereto. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features within the scope of the technology disclosed in this disclosure.
