The adhesive layer 16 connects the diaphragm 14 and the second surface 22, and the adhesive layer 16 is provided with a through hole 26. The touch switch assembly 18 is mounted on the second surface 22. The touch switch assembly 18 includes a touch button 28. In the direction from the first surface 20 to the second surface 22 in the first direction, the through hole 26, the icon 24 and the touch button 28 are arranged in sequence.

[0034] In the above panel assembly 100, the second surface 22 of the panel 12 is connected to the diaphragm 14 having the icon 24 through the adhesive layer 16, so that the fitting degree between the panel 12 and the diaphragm 14 can be improved, and quality risks such as touch failure can be avoided or reduced to a certain extent.

[0035] Specifically, household appliances include but are not limited to range hoods, cooktops, dishwashers, microwave ovens, microwave ovens with grills, microwave steam and grill combination ovens, etc. In one embodiment, the household appliance is a range hood. The panel assembly 100 can be mounted on the front side of the range hood.

[0036] The material of the panel 12 includes, but is not limited to, glass, acrylic, and PC (Polycarbonate). The panel 12 can be a light-transmitting panel 12. The panel 12 can have a shape including, but not limited to, a flat shape. In Figure 1 , the first direction is the front-back direction, the first surface 20 is the front surface of the panel 12, and the second surface 22 is the back surface of the panel 12. The thickness and shape of the panel 12 can be specifically determined according to the actual situation, and the present utility model does not make specific limitations thereon.

[0037] Icons 24 are provided on the diaphragm 14. The present utility model does not make specific limitations on the number of the icons 24. In Figure 1 , the number of the icons 24 provided on the diaphragm 14 is multiple, and the multiple icons 24 are arranged at intervals along the second direction. The second direction is the left-right direction. The icons 24 can be formed on the diaphragm 14 by means including, but not limited to, spray painting and screen printing. The icons 24 can be provided on the surface of the diaphragm 14 facing away from the adhesive layer 16 (such as the back surface of the diaphragm 14), or can also be provided on the surface of the diaphragm 14 facing the adhesive layer 16 (such as the front surface of the diaphragm 14).

[0038] The appearance presented by the icons 24 can be designed according to the style of real objects. For example, the light switch icon 24 can be designed in the style of a light bulb emitting light, the air volume increasing icon 24 can be designed in the style of a fan blade with a large number, the air volume decreasing icon 24 can be designed in the style of a fan blade with a small number. The heating switch icon 24 can be designed in the style of a heating tube, etc., so as to achieve a super-real user interface (UI) display. In Figure 1 , the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction. It can be understood that the present utility model does not limit the specific directions of the first direction, the second direction, and the third direction.

[0039] The material of the diaphragm 14 includes, but is not limited to, PET (Polyethylene terephthalate) or PC material. The thickness and shape of the diaphragm 14 are specifically determined according to the actual situation, and the present utility model does not make specific limitations thereon. In Figure 1 , the diaphragm 14 is in a flat cuboid shape.

[0040] The adhesive layer 16 can be a double-sided adhesive. The adhesive layer 16 connects the diaphragm 14 and the second surface 22, so that the diaphragm 14 can be better attached to the panel 12, the adhesion between the panel 12 and the diaphragm 14 can be improved, and the quality risks such as touch failure can be avoided or reduced to a certain extent. The through holes 26 on the adhesive layer 16 can form light-transmitting holes, which can facilitate users to observe the icons 24 from the front side of the panel 12 (the side where the first surface 20 is located) for corresponding operations. In Figure 1In this case, the second side 22 of the panel 12 is the back side of the panel 12. The adhesive layer 16 can serve as the back adhesive of the panel assembly 100, connecting the diaphragm 14 and the back side of the panel 12, and is used to display and transmit the switch touch medium.

[0041] The area of the diaphragm 14 with the adhesive layer 16 is fixedly adhered to the second side 22 of the panel 12. An icon 24 is provided in the area of the diaphragm 14 without the adhesive layer 16.

[0042] Optionally, the touch switch assembly 18 can be a capacitive touch switch assembly 18. The touch switch assembly 18 can sense capacitance changes to achieve touch control. The touch switch assembly 18 is mounted on the second side 22. The touch switch assembly 18 further includes a body 46. The touch button 28 is provided on the side of the body 46 facing the diaphragm 14. The body 46 can include a housing and a circuit board. The circuit board is located inside the housing and is connected to the touch button 28. In Figure 1 and Figure 4 In this case, in the first direction, the direction from the first side 20 to the second side 22 is the front-to-back direction, that is, the front-to-back direction. The through hole 26, the icon 24, and the touch button 28 are arranged in sequence. Thus, when the user observes the panel 12 from the front side of the panel 12, the icon 24 can be seen. When the user touches the area on the panel 12 corresponding to the icon 24, the touch button 28 can be triggered, so that the corresponding functions of the icon 24, such as turning on / off, adjusting, etc., can be realized, such as turning on / off the light, adjusting the wind speed gear, etc.

[0043] In some embodiments, a light-shielding area 30 and a light-transmitting area 32 are provided on the second side 22. Along the first direction, the light-transmitting area 32 corresponds to the icon 24.

[0044] Thus, the icon 24 can be more easily perceived by the user.

[0045] Specifically, the entire panel 12 can be a light-transmitting panel 12. The second side 22 includes an area corresponding to the icon 24 in the first direction. This area can be used as the light-transmitting area 32. Optionally, the area of the light-transmitting area 32 can be the same as or slightly larger than the area of the icon 24. An ink layer can be formed on other areas outside the light-transmitting area 32 to block light, thereby forming the light-shielding area 30. When observing the panel 12 from the side where the first side 20 of the panel 12 is located, the light transmittance difference between the light-shielding area 30 and the light-transmitting area 32 is large, so that the user can more easily see the icon 24, facilitating the user operation.

[0046] The color of the ink layer includes but is not limited to black.

[0047] In some embodiments, please refer to Figure 3 , in the first direction from the first side 20 to the second side 22, the icon 24 falls within the range of the light-transmitting area 32.

[0048] Thus, the icon 24 can be made more perceptible.

[0049] Specifically, in Figure 1 、 Figure 3 and Figure 4 , the direction from the first surface 20 to the second surface 22 in the first direction is the front-to-back direction. In the front-to-back direction, the icon 24 falls within the range of the light-transmitting area 32, that is, the area of the icon 24 is smaller than the area of the light-transmitting area 32. When viewing the panel 12 from the side where the first surface 20 of the panel 12 is located, the icon 24 is within the range of the light-transmitting area 32, making the icon 24 clearer and more visible, easier for the user to see the icon 24, and facilitating the user's operation.

[0050] In some embodiments, the touch button 28 includes a conductive elastic member 34. A touch area 36 is provided on the surface of the elastic member 34 facing the diaphragm 14. In the first direction, the touch area 36 corresponds to the icon 24.

[0051] Thus, it can be achieved that touching the icon 24 can trigger the touch button 28.

[0052] Specifically, the elastic member 34 can allow for the assembly error existing between the touch switch assembly 18 and the panel 12. In Figure 1 , the first direction is the front-to-back direction. The surface of the elastic member 34 facing the diaphragm 14 is the front surface of the elastic member 34, and a touch area 36 is provided on the front surface of the elastic member 34. In the front-to-back direction, the icon 24 corresponds to the touch area 36. When the user touches the area corresponding to the icon 24 (such as the light-transmitting area 32 area) of the panel 12 from the side where the first surface 20 of the panel 12 is located, the touch button 28 corresponding to the icon 24 can be triggered, thereby realizing the corresponding function.

[0053] In some embodiments, the touch button 28 includes a light-emitting area 38. The touch area 36 is arranged around the light-emitting area 38. Along the first direction, the icon 24 corresponds to the light-emitting area 38.

[0054] Thus, the icon 24 can be made more easily perceptible.

[0055] Specifically, in Figure 1 and Figure 4 , the first direction is the front-to-back direction. Along the front-to-back direction, the icon 24 corresponds to the light-emitting area 38. The light-emitting area 38 can emit light, and the light illuminates the icon 24. The user can more easily observe the illuminated icon 24 on the front side of the panel 12, facilitating the user's operation.

[0056] The touch button 28 may include a light-emitting portion 40. The surface of the light-emitting portion 40 facing the icon 24 forms a light-emitting area 38. The light-emitting portion 40 may include, but is not limited to, a light-emitting diode.

[0057] The touch area 36 is arranged around the light-emitting area 38, so that the light-emitting area 38 can illuminate the icon 24 from the middle, which is beneficial to improving the brightness uniformity of the icon 24. Please refer to Figure 3 , the touch area 36 is in a circular ring shape, and the light-emitting area 38 is located in the middle area of the touch area 36.

[0058] Optionally, in the first direction, the light-emitting area 38 can cover the area of the icon 24 on the diaphragm 14, so as to ensure the display effect.

[0059] It can be understood that in other embodiments, the touch switch assembly 18 can also be other touch switch assemblies, rather than being limited to the touch switch assembly 18 with the elastic member 34. In the first direction, the touch area 36, the icon 24, and the light-transmitting area 32 of the touch switch assembly 18 are correspondingly arranged.

[0060] In some embodiments, the surface of the elastic member 34 facing the diaphragm 14 is in contact with the diaphragm 14.

[0061] Thus, the problem of touch failure can be avoided or reduced to a certain extent.

[0062] Specifically, in Figure 4 , the surface of the elastic member 34 facing the diaphragm 14 is the front surface of the elastic member 34. When the touch switch assembly 18 is installed on the second surface 22 of the panel 12, the front surface of the elastic member 34 can be in close contact with the back surface of the diaphragm 14. Thus, when the user touches the area corresponding to the icon 24 on the panel 12 on the side where the first surface 20 of the panel 12 is located, the success rate of triggering the touch button 28 can be improved to achieve the corresponding function. Optionally, in one embodiment, the elastic member 34 can be a touch sensing spring.

[0063] In some embodiments, please refer to Figure 3 , in the first direction, the edge of the through hole 26 is within the range of the touch area 36.

[0064] Thus, the touch sensitivity can be improved.

[0065] Specifically, in Figure 3 , the range of the touch area 36 is in a circular ring shape, and the edge of the through hole 26 is between the outer circle and the inner circle of the ring. That is to say, the part of the adhesive layer 16 surrounding the through hole 26 is within the range of the touch area 36 in the first direction. This part can make the diaphragm 14 in contact with the second surface 22 of the panel 12, ensuring a gapless and close contact among the elastic member 34, the diaphragm 14, and the panel 12, thereby improving the touch sensitivity.

[0066] In some embodiments, the panel assembly 100 includes a first bracket 42 and a second bracket 44. The first bracket 42 is disposed on the second surface 22. The touch switch assembly 18 includes a body 46. The touch button 28 is disposed on one surface of the body 46 along a first direction. The second bracket 44 is disposed on the surface of the body 46 along a second direction. The first bracket 42 and the second bracket 44 are connected to mount the touch switch assembly 18 on the second surface 22, and the first direction is perpendicular to the second direction.

[0067] Thus, the touch switch assembly 18 can be mounted on the second surface 22.

[0068] Specifically, in Figure 1 ..., the first direction is the front-back direction, and the second direction is the left-right direction. The panel assembly 100 includes two first brackets 42. Two second brackets 44 are provided on the body 46. The two first brackets 42 are spaced apart along the second direction. The diaphragm 14 is located between the two first brackets 42. The two second brackets 44 are respectively disposed on both sides of the body 46 along the second direction. During installation, the first bracket 42 and the second bracket 44 are connected in one-to-one correspondence (by means including but not limited to bolts, welding, etc.) to mount the touch switch assembly 18 on the second surface 22 (such as the back surface) of the panel 12.

[0069] The first bracket 42 can be fixed on the second surface 22 of the panel 12 by means including but not limited to bolts, gluing, etc. Optionally, the second bracket 44 can be integrally connected with the housing of the body 46. The height of the first bracket 42 relative to the second surface 22 can be used to adjust the distance between the touch switch assembly 18 and the panel 12.

[0070] An appliance according to an embodiment of the present invention includes the panel assembly 100 according to any of the above embodiments.

[0071] In the above appliance, the second surface 22 of the panel 12 and the diaphragm 14 with the icon 24 are connected through the adhesive layer 16, so as to improve the fitting degree between the panel 12 and the diaphragm 14, and avoid or reduce quality risks such as touch failure to a certain extent.

[0072] In some embodiments, the appliance includes a range hood or an integrated stove.

[0073] Thus, the range hood or the integrated stove can apply the panel assembly 100 of this embodiment.

[0074] Optionally, in one embodiment, the range hood includes a smoke collecting cavity, and the panel assembly 100 can be disposed on the front side surface of the smoke collecting cavity.
