[0039] Embodiment 1

[0040] like Figure 1 and Figure 2 As shown, the first embodiment of the utility model provides a panel mechanism, which includes a panel body 1 and a light assembly 2. The panel body 1 includes an exterior panel 11 and a support shell 12 connected to the inner side of the exterior panel 11. A receiving cavity 13 is formed between the exterior panel 11 and the support shell 12. The exterior panel 11 has a light-transmitting window 111. The exterior panel 11 forms a light-transmitting window 111 through which light can pass in some areas by removing the film or spraying the opaque material, etc., without destroying the structural strength and integrity of the panel body 1. The light assembly 2 is detachably connected to the panel body 1 and is disposed in the receiving cavity 13. The light assembly 2 includes a light bar 21, and the light emitted by the light bar 21 is emitted through the light-transmitting window 111. Since the light assembly 2 is disposed in the receiving cavity 13, the light is emitted from the light-transmitting window 111 of the exterior panel 11, without destroying the integrity and aesthetics of the panel body 1. Moreover, the panel body 1 can provide protection for the lighting component 2 to prevent the lighting component 2 from being damaged; the lighting component 2 is easy to install in the accommodating cavity 13, and can be fixed to the exterior panel 11 or the supporting shell 12 by bonding, welding, etc., without the need for additional protective structures and installation structures such as lampshades and mounting frames, thereby avoiding increasing production costs, and the installation method and installation process are relatively simple.

[0041] The exterior panel 11 includes but is not limited to a glass plate, and may also be other plastic panels or metal panels with decorative functions. The lighting component 2 includes but is not limited to an atmosphere lamp, and may also be a lighting body with a lighting function. When the lighting component 2 is an atmosphere lamp, an LED lamp may be used. The LED lamp has a variety of colors and can form a light intensity effect of a breathing lamp, which can be selected and set according to the specific working mode of the range hood. For example, different colors can be displayed to correspond to the working mode of the range hood. When the range hood is in a stir-frying mode, the lighting component 2 can be displayed in red; when the range hood is in a high-end large air volume mode, the lighting component 2 can be displayed in blue; when the range hood is in a low-end small air volume mode, the lighting component 2 can be displayed in white. In addition, when the range hood is started and shut down, the user can intuitively feel the startup process and shutdown process through the breathing light effect, making the kitchen usage scene more technological and closer to the needs of contemporary people.

[0042] It should be noted that the lighting assembly 2 can also be applied to other electrical appliances besides the range hood, such as electric fans, gas stoves, etc., and this embodiment 1 does not make any specific limitation.

[0043] In order to guide the light, the lighting assembly 2 also includes a light guide plate 22, which is connected to the light-emitting side of the light bar 21, and is used to guide the light emitted by the light bar 21 to the light-transmitting window 111. The light guide plate 22 and the light bar 21 are connected together, which can prevent the light bar 21 from deforming while guiding the light. The light guide plate 22 is preferably formed by processing an acrylic plate, which has good structural strength, does not require mold auxiliary processing, and reduces production costs. The light guide plate 22 can form a uniform distribution of the light emitted by the LED lamp to form a planar light source. Since the panel body 1 needs to maintain a relatively thin width, the width of the accommodating cavity 13 is limited, that is, the distance between the exterior panel 11 and the supporting shell 12 is relatively limited. If the light-emitting side of the light bar 21 is parallel to the exterior panel 11, the distance between the exterior panel 11 and the supporting shell 12 is too narrow, which will affect the installation of the light guide plate 22. Therefore, the light-emitting side of the light bar 21 should be arranged perpendicular to the exterior panel 11 to avoid the problem of insufficient width of the panel body 1, resulting in insufficient installation of the light guide plate 22.

[0044] Further, in this embodiment Figure 1 In the embodiment, the height of the light guide plate 22 is h1, referring to the second embodiment. Figure 3 , the height of the light guide plate 22 is h2. Therefore, in order to meet the different sizes of the light guide plate 22 so as to form light-emitting areas with different effects, the light-emitting side of the light bar 21 is arranged perpendicular to the exterior panel 11, so that the height direction of the light guide plate 22 can extend along the height direction of the accommodating cavity 13, so that the light guide plate 22 can be formed to any height without being limited by the distance between the exterior panel 11 and the supporting shell 12. For example, in this embodiment Figure 2 and Example 2 Figure 4 In the embodiment, the sizes of the light assembly 2 are different, which is also formed by the different heights of the light guide plate 22, thereby forming light-emitting areas with different effects.

[0045] Optionally, the lighting assembly 2 further includes an insulating film layer 23, which is coated on the partial outer surface of the light guide plate 22 and the light bar 21, and the outer surface of the light guide plate 22 not covered by the insulating film layer 23 forms a light emitting surface 221. The insulating film layer 23 can be made of an insulating sticker, which is pasted and coated on the surface of the light guide plate 22 and the light bar 21, so that the lighting assembly 2 is packaged to form a module. On the one hand, the insulating sticker can provide insulation protection for the light guide plate 22 and the light bar 21, and on the other hand, no light will be emitted from the surface of the light guide plate 22 and the light bar 21 covered by the insulating sticker, so that the light can only be emitted through the light emitting surface 221, and the emission direction of the light is limited, so that the light is more concentrated and the loss of light energy is avoided.

[0046] In order to form a gradual lighting effect, the orthographic projection of the lighting assembly 2 on the exterior panel 11 is located outside the light-transmitting window 111, so that the light-emitting surface 221 and the light-transmitting window 111 are arranged alternately, so that the light-emitting surface 221 is located on one side of the light-transmitting window 111, and the light emitted from the light-emitting surface 221 is reflected between the exterior panel 11 and the supporting shell 12, and finally emitted from the light-transmitting window 111. Since the light-emitting surface 221 is arranged on one side of the light-transmitting window 111, the reflection paths of the emitted light at different positions of the light-transmitting window 111 are different, so that different light intensities are formed at different positions of the light-transmitting window 111, that is, the light intensity emitted from the light-transmitting window 111 gradually decreases from the side close to the light-emitting surface 221 to the side away from the light-emitting surface 221, forming a gradual lighting effect.

[0047] When the light-transmitting window 111 is a rectangular window, the light-emitting surface 221 can be disposed on any side of the rectangle. Figure 5 When the light-transmitting window 111 extends horizontally along the length direction of the exterior panel 11, the light-emitting surface 221 can be arranged at the lower side of the light-transmitting window 111. Figure 1 As shown, this arrangement can form a horizontally extending light band and form a gradually weakening gradient lighting effect from bottom to top at the light-transmitting window 111 .

[0048] Optionally, the light assembly 2 further includes a soft light plate 24, which is attached to the light emitting surface 221. The soft light plate 24 can make the light softer and more natural, has the effect of softening the light, further improves the visibility of the light emitted from the light-transmitting window 111, and avoids the formation of more irritating light. The soft light plate 24 can be made of PC plastic, and the processing technology is simple, and does not require mold auxiliary processing.

[0049] There are many ways to fix the light assembly 2. Specifically, the light assembly 2 is bonded to the support housing 12 or the exterior panel 11, and is sandwiched between the exterior panel 11 and the support housing 12. The light assembly 2 has been packaged as a module by the bonding of the insulating film layer 23. The position can be fixed by gluing, and the assembly process is simple. The exterior panel 11 and the support housing 12 are sandwiched on both sides to reduce the risk of displacement and deformation of the light assembly 2.

[0050] In order to position and support the light assembly 2, the panel body 1 also includes a positioning support 14 disposed in the accommodating cavity 13. The positioning support 14 is connected to the exterior panel 11 and / or the supporting shell 12, and the positioning support 14 is used to support the light assembly 2. The positioning support 14 supports the lower surface of the light assembly 2 to prevent the light assembly 2 from shifting after the adhesive fails. The positioning support 14 can be an L-shaped sheet metal bracket, or a block made of plastic, and the specific structure is not limited in this embodiment. Preferably, a plurality of positioning supports 14 are provided, and the plurality of positioning supports 14 are spaced apart along the extension direction of the light-transmitting window 111 to provide multi-point support for the entire strip-shaped light assembly 2.

[0051] Optionally, the positioning support 14 is bonded to the exterior panel 11, and the panel body 1 further includes a fastener, which passes through the support shell 12 to connect the positioning support 14. Preferably, silicone adhesive is used to bond the positioning support 14 to the exterior panel 11, and the bonding reliability is good. Screw holes are provided on the positioning support 14, and a through mounting hole is provided on the support shell 12. Fasteners such as screws pass through the mounting holes and are threadedly connected to the positioning support 14. This mounting structure not only realizes the limited support of the lighting assembly 2, but also realizes the detachable connection between the exterior panel 11 and the support shell 12, and does not affect the aesthetics of the exterior panel 11.

[0052] The panel body 1 further includes a seal 15, which is disposed between the outer panel 11 and the support shell 12, and is used to fill the gap between the outer panel 11 and the support shell 12. Figure 1 As shown, the support housing 12 forms a bent mounting edge around the periphery, the outer decorative panel 11 fits the mounting edge, and the seal 15 is arranged between the mounting edge and the outer decorative panel 11 to form a seal. The seal 15 can improve the sealing of the accommodating cavity 13 and prevent light from leaking around the outer decorative panel 11.

[0053] Embodiment 2

[0054] like Figure 3 and Figure 4 As shown, the second embodiment provides a panel mechanism, which includes a panel body 1 and a lighting assembly 2. The panel body 1 includes an exterior panel 11 and a supporting shell 12 connected to the inner side of the exterior panel 11. A receiving cavity 13 is formed between the exterior panel 11 and the supporting shell 12. The exterior panel 11 has a light-transmitting window 111. The lighting assembly 2 is detachably connected to the panel body 1 and is disposed in the receiving cavity 13. The lighting assembly 2 includes a light bar 21. Light energy emitted by the light bar 21 is emitted through the light-transmitting window 111.

[0055] The difference of the second embodiment is that, unlike the first embodiment in which the light emitting surface 221 is located on one side of the light transmission window 111 to form a gradual lighting effect, at least one light bar 21 is disposed on both opposite sides of the light guide plate 22 in the second embodiment, and the light emitting surface 221 is disposed on the side of the light guide plate 22 facing the exterior panel 11, and the light guide plate 22 covers the light transmission window 111 so that the light emitting surface 221 faces the light transmission window 111. Figure 3 As shown, the light emitted by the two light bars 21 is reflected inside the light guide plate 22 and finally emitted from the light-transmitting window 111, forming a uniform light effect. Preferably, the two light bars 21 are symmetrically arranged on both sides of the light-transmitting window 111, so that the light intensity of the entire light-transmitting window 111 is more uniform.

[0056] Embodiment 3

[0057] The third embodiment of the present utility model provides a range hood, such as Figure 5 and Figure 6 As shown, the range hood includes a panel mechanism as in the above-mentioned embodiment 1 or embodiment 2, and the range hood also includes a smoke collecting cavity 100. The front plate of the smoke collecting cavity 100 is provided with a smoke inlet 101, and the panel body 1 is connected to the front plate and arranged above the smoke inlet 101. The range hood cleverly utilizes the internal space of the panel body 1, and realizes the installation of the light assembly 2 through the accommodating cavity 13 formed by the outer decorative panel 11 and the supporting shell 12. The light energy emitted by the light bar 21 is emitted through the light-transmitting window 111 of the outer decorative panel 11, and will not damage the integrity and aesthetics of the panel body 1. Moreover, the panel body 1 can provide protection for the light assembly 2 to prevent the light assembly 2 from being damaged; the light assembly 2 is easy to install in the accommodating cavity 13, and can be fixed to the outer decorative panel 11 or the supporting shell 12 by bonding, welding, etc., without the need to additionally set up protective structures and installation structures such as lampshades and mounting frames, thereby avoiding increasing production costs, and the installation method and installation process are relatively simple.

[0058] The indication principle and implementation method of the light assembly 2 and the working status can be set with reference to the prior art. This is not the focus of this application and will not be elaborated in this third embodiment.

[0059] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
