In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The panel assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, the panel assembly 10 according to the embodiment of the utility model includes a panel 1, a circuit board 2, a shading member 3 and a light diffuser 4.

[0036] Specifically, Figure 1 As shown, the panel 1 can be used in household appliances such as an air conditioner 100. The panel 1 can be the panel 1 of the air conditioner 100. One of the two sides in the thickness direction of the panel 1 is the outer side of the panel 1, that is, the side of the panel 1 facing away from the inside of the air conditioner 100, and the other side of the two sides in the thickness direction of the panel 1 is the inner side of the panel 1, that is, the side of the panel 1 facing the inside of the air conditioner 100. Figure 1 and Figure 2 As shown, the circuit board 2 is arranged on one side of the panel 1 in the thickness direction and is spaced apart from the panel 1, for example, Figure 1 As shown, the circuit board 2 is disposed inside the panel 1 and spaced apart from the panel 1. It is understandable that the circuit board 2 is disposed inside a household appliance such as an air conditioner 100, which can ensure that the appearance of the air conditioner 100 is neat and beautiful.

[0037] like Figure 2 As shown, a photosensitive receiver 21 is provided on the side of the circuit board 2 facing the panel 1. It can be understood that a display element or an indicator light can also be provided on the side of the circuit board 2 facing the panel 1. The display element is used to display data information. For example, when the panel assembly 10 is used for the air conditioner 100, the display element can display the operating status of the air conditioner 100 (cooling, heating, humidification, etc.), the current operating temperature of the air conditioner 100 and other information. The photosensitive receiver 21 can receive light from the room outside the panel 1, and adjust the brightness of the display element or the indicator light according to the indoor light, so as to ensure the comfort of the user.

[0038] For example, during the day, the indoor light is brighter, and the brightness received by the photosensitive receiver 21 is larger, so the brightness of the display or indicator light can be controlled to be larger. At night, when the user is sleeping, the indoor light is dim, and the brightness received by the photosensitive receiver 21 is lower, so the brightness of the display or indicator light can be controlled to be reduced or turned off to ensure the user's comfort.

[0039] The shading member 3 is located between the circuit board 2 and the panel 1 and is arranged around the photosensitive receiver 21. The shading member 3 can ensure that the light received by the photosensitive receiver 21 comes from the light passing through the panel 1 directly opposite to the photosensitive receiver 21, and prevent light from other places, such as the light of the display or indicator light on the circuit board 2, from being received by the photosensitive receiver 21 and affecting the detection of the photosensitive receiver 21.

[0040] The light homogenizer 4 is arranged on the side of the panel 1 facing the circuit board 2 and is arranged opposite to the photosensitive receiver 21. For example, the light homogenizer 4 can be attached to the panel 1 to evenly project the light received at different angles through the panel 1 onto the photosensitive receiver 21. Figure 3 and Figure 4 As shown, the light passing through the panel 1 can be prevented from being affected by the position of the indoor light, the panel 1 process (spraying, lamination or injection molding, etc.) and the position of the photosensitive receiving head, effectively solving the problem of photosensitivity failure caused by inconsistent light intensity at different angles, and ensuring the reliability of the photosensitive receiver 21.

[0041] Table 1 below shows the photosensitivity test data of different panels 1 under different light intensities and different light incident angles.

[0042] Table 1 The photosensitivity test data of the panel of the utility model

[0043]

[0044]

[0045] It can be seen from Table 1 that, when the light homogenizer 4 is provided, under the same light intensity, the data received by the photosensitive receiver 21 is substantially the same for light incident at different angles.

[0046] According to the panel assembly 10 of the embodiment of the utility model, by arranging a light homogenizer 4 on the side of the panel 1 facing the circuit board 2 and making the light homogenizer 4 arranged opposite to the photosensitive receiver 21, the light received at different angles through the panel 1 can be evenly projected onto the photosensitive receiver 21, and the light passing through the panel 1 can be prevented from being affected by the position of the indoor lights, the panel 1 process and the position of the photosensitive receiving head, thereby effectively solving the problem of photosensitivity failure caused by inconsistent light intensity at different angles, and ensuring the reliability of the photosensitive receiver 21.

[0047] In some embodiments of the present invention, Figure 2As shown, the projection of the shading member 3 on the panel 1 is located within the projection of the light homogenizer 4 on the panel 1. It can be understood that in the direction from the panel 1 to the circuit board 2, the light homogenizer 4 can completely block the shading member 3 and the space inside the shading member 3, so that the light entering the shading member 3 and received by the photosensitive receiver 21 is all homogenized by the light homogenizer 4, ensuring the reliability of the photosensitive receiver 21.

[0048] Optionally, the shape of the light homogenizer 4 can be the same as the shape of the outer contour of the projection of the shading member 3 on the panel 1, and the outer edge of the projection of the light homogenizer 4 on the panel 1 is flush with the outer contour of the projection of the shading member 3 on the panel 1 or exceeds the outer contour of the projection of the shading member 3 on the panel 1.

[0049] Of course, the utility model is not limited to this, and the light homogenizer 4 can also be located on the inner side of the end of the shading member 3 close to the circuit board 2, wherein the outer contour of the light homogenizer 4 can also be flush with or spaced apart from the inner contour of the end of the shading member 3 close to the circuit board 2. Of course, the light homogenizer 4 can also cover the inner side of the entire panel 1, that is, the surface of the panel 1 facing the circuit board 2, and the light homogenizer 4 covers the surface of the entire panel 1 facing the circuit board 2, and the light homogenizer 4 can have a hollow area at the position of the display or indicator light.

[0050] In some embodiments of the present invention, Figure 2 As shown, one axial end of the shading member 3, that is, the end of the shading member 3 that is away from the panel 1, is connected to the circuit board 2, and the other end, that is, the end of the shading member 3 that is away from the circuit board 2, abuts against the light homogenizer 4 or the panel 1. It can be understood that when the projection of the shading member 3 on the panel 1 is located within the projection of the light homogenizer 4 on the panel 1, the shading member 3 is located between the light homogenizer 4 and the circuit board 2, and the end of the shading member 3 that is away from the circuit board 2 abuts against the light homogenizer 4; when the light homogenizer 4 is located on the radial inner side of the shading member 3, the end of the shading member 3 that is away from the circuit board 2 abuts against the panel 1. In this way, the problem of light leakage due to the gap between the shading member 3 and the panel 1 can be avoided, and the reliability of the operation of the photosensitive receiver 21 can be ensured.

[0051] Optionally, the shading member 3 is an elastic member, such as a rubber member or a silicone member, so as to ensure that the shading member 3 abuts against the panel 1 or the light-distributing sheet 4 without causing interference between the panel 1 and the shading member 3 .

[0052] Of course, the present invention is not limited thereto, and the shading member 3 may have only a portion close to one end of the panel 1 as an elastic member, and a portion close to the circuit board 2 as a rigid member.

[0053] In some embodiments of the present invention, the shading member 3 is snap-connected to the circuit board 2, thereby improving the reliability of the connection between the shading member 3 and the circuit board 2, simplifying the connection method between the shading member 3 and the circuit board 2, and improving assembly efficiency.

[0054] For example, in Figure 2 In the example shown, the circuit board 2 is provided with a clamping hole 22, and the end of the shading member 3 facing away from the panel 1 is provided with a clamping hook 33 that cooperates with the clamping hole 22. There are multiple clamping holes 22, and there are multiple clamping hooks 33 that cooperate with multiple clamping holes 22. The multiple clamping hooks 33 are arranged at intervals along the circumferential direction of the shading member 3.

[0055] In some embodiments of the present invention, Figure 2 As shown, along the axial direction of the shading member 3, the shading member 3 includes a first section 31 and a second section 32, one end of the first section 31 is connected to the circuit board 2, along the axial direction of the shading member 3, the inner contour size of the first section 31 remains unchanged, one end of the second section 32 is connected to the end of the first section 31 away from the circuit board 2, and the other end of the second section 32 abuts against the light homogenizer 4 or the panel 1, and in the direction from the first section 31 to the second section 32, the inner wall surface of the second section 32 is inclined toward the direction away from the axis of the shading member 3. It can be understood that the first section 31 is formed in a straight cylinder shape, and the second section 32 is formed in a trumpet shape, and the second section 32 can play a role in focusing light, so that the photosensitive receiver 21 can receive light and improve the reliability of the photosensitive receiver 21.

[0056] The first section 31 and the second section 32 may both be elastic members, or the first section 31 may be a rigid member and the second section 32 may be an elastic member.

[0057] Optionally, the thickness of the second section 32 is smaller than the thickness of the first section 31 , thereby facilitating the second section 32 to deform and abut against the panel 1 or the light homogenizing sheet 4 .

[0058] Optionally, the light homogenizing sheet 4 is a PET (polyethylene glycol terephthalate) diffusion film. When light passes through the diffusion layer with PET as the base material, it will pass through the medium with different refractive index, causing many refractions, reflections and scattering phenomena of the light, which can correct the light into a uniform surface light source to achieve the effect of optical diffusion.

[0059] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the panel assembly 10 further includes a box cover 5, which is disposed on one side of the panel 1 in the thickness direction and defines a mounting cavity 51 together with the panel 1, and the circuit board 2 and the light shielding member 3 are disposed in the mounting cavity 51. This can protect components such as the circuit board 2 and ensure the reliability of the components such as the circuit board 2.

[0060] Optionally, the box cover 5 is connected to the panel 1 by snapping and / or by fasteners. It is understandable that the box cover 5 and the panel 1 can be connected only by snapping, or the box cover 5 and the panel 1 can be connected only by fasteners, or the box cover 5 and the panel 1 can be connected by fasteners and snapping. This can not only improve the reliability of the connection between the box cover 5 and the panel 1, but also simplify the connection between the panel 1 and the box cover 5.

[0061] In some embodiments of the utility model, a coating is adhered to the surface of the panel 1 facing away from the circuit board 2, and a hollow area is provided relative to the circuit board 2, thereby facilitating light to pass through the panel 1 and be received by the photosensitive receiver 21, and facilitating light from the display element on the circuit board 2 to pass through the circuit board 2 and be displayed outwardly, so as to facilitate user viewing.

[0062] In some embodiments of the present invention, the thickness of the area on the panel 1 opposite to the circuit board 2 is smaller than the thickness of the remaining areas, thereby facilitating light to pass through the panel 1 and be received by the photosensitive receiver 21, and facilitating light from the display element on the circuit board 2 to pass through the circuit board 2 and be displayed outwardly, which is convenient for users to view.
