[0031] The following reference Figure 1 and Figure 2 This application describes a touch panel assembly and kitchen appliance according to some embodiments.

[0032] This application provides a touch panel component, such as Figure 1 As shown, the touch panel assembly includes a glass cover plate 5, a color filter 3, and a button frame 1. The glass cover plate 5 is fixedly installed on the touch screen frame 4 of the kitchen appliance. The color filter 3 and the button frame 1 are located on the same side of the glass cover plate 5, and the color filter 3 is located between the glass cover plate 5 and the button frame 1. The color filter 3 is in contact with the surface of the glass cover plate 5. The button frame 1 is fastened to the touch screen frame 4 and presses against the color filter 3 so that the color filter 3 is tightly attached to the glass cover plate 5 under the pressure of the button frame 1.

[0033] An elastic plastic pad 2 is laid on the surface of the button panel frame 1 facing the color film 3. When the button panel frame 1 is fastened to the touch screen frame 4, the button panel frame 1 presses against the color film 3 through the elastic plastic pad 2, causing the elastic plastic pad 2 to compress. Thus, when the button panel frame 1 deforms, the elastic plastic pad 2 can absorb the deformation, allowing the color film 3 to still be under stable pressure and maintain a tight fit with the glass cover plate 5. This prevents gaps from appearing between the color film 3 and the glass cover plate 5 due to the deformation of the button panel frame 1, which would affect the touch effect of the touch panel assembly.

[0034] In one embodiment of this application, preferably, the elastic plastic pad 2 is a silicone pad or a polyurethane foam pad. Both silicone pads and polyurethane foam pads have good elasticity, which can absorb the deformation of the keypad frame 1. At the same time, silicone pads and polyurethane foam pads are easier to process, for example, through precision cutting, to ensure that the thickness of the elastic plastic pad 2 is controllable, ensuring the uniform thickness of the touch panel assembly and improving the user experience. In addition, both silicone pads and polyurethane foam pads have good heat resistance and weather resistance, so that they will not age after long-term use, and the touch panel assembly has good stability during long-term use.

[0035] In one embodiment of this application, preferably, as shown below, Figure 1 As shown, the elastic plastic pad 2 is provided in two layers, and the two layers of elastic plastic pad 2 are stacked on the keypad frame 1 in sequence. The two layers of elastic plastic pad 2 have different hardnesses. The layer of elastic plastic pad 2 closer to the keypad frame 1 has a larger hardness, and the layer of elastic plastic pad 2 farther away from the keypad frame 1 has a smaller hardness.

[0036] For example, when two layers of elastic plastic pads 2 are laid on the keypad frame 1, the layer of elastic plastic pads 2 closer to the keypad frame 1 is a polyurethane foam pad with higher hardness, and the layer of elastic plastic pads 2 further away from the keypad frame 1 is a silicone pad with lower hardness; thus, while the elastic plastic pads 2 absorb the deformation of the keypad frame 1 by relying on their good elasticity, they can also provide sufficient pressure to the color film 3, so that the color film 3 adheres more tightly to the glass cover plate 5.

[0037] In this embodiment, preferably, when using a silicone pad, the thickness of the silicone pad is not less than 1 mm, the hardness of the silicone pad can reach Shore A60, the tensile strength can reach 7 MPa, the elongation at break can reach 300%, the heat resistance temperature can reach 200 degrees Celsius, and the weather resistance is UV-A grade.

[0038] Preferably, when using polyurethane foam pads, the thickness of the polyurethane foam pads is not less than 1 mm, and its density is 0.03 g / cm³. 3 Its compressive strength can reach 0.3 MPa.

[0039] In one embodiment of this application, preferably, the elastic plastic pad 2 and the keypad frame 1 are bonded together by a light-curing adhesive or a double-sided adhesive film, thereby ensuring the bonding strength and uniformity between the elastic buffer pad and the keypad frame 1, and ensuring the stability of the touch panel assembly.

[0040] When the elastic plastic pad 2 has two layers, the two layers of elastic plastic pad 2 can also be bonded together with light-curing adhesive or double-sided film.

[0041] In one embodiment of this application, preferably, as shown below, Figure 1 and 2 As shown, the keypad frame 1 has multiple light-transmitting areas 11 with light sources installed. The elastic plastic pad 2 has a matching light-transmitting hole 21 at the position opposite to each light-transmitting area 11, so as not to obstruct the light source on the keypad frame 1 from illuminating the color film 3 and the glass cover 5. At the same time, the elastic plastic pad 2 covers the other areas on the keypad frame except for the light-transmitting areas 11, so that when the keypad frame 1 presses against the color film 3, it can provide uniform pressure to the color film 3 along the plane of the color film 3, and at the same time, it can also prevent light leakage between the multiple light-transmitting areas 11.

[0042] In an embodiment of the present application, preferably, the key plate frame 1 is an ABS (Acrylonitrile Butadiene Styrene plastic) plastic frame, an ACF (Artificial Cartilage Foam) artificial cartilage frame or an EPP (Expanded polypropylene) foamed polypropylene frame. Thus, the key plate frame 1 has good impact resistance and weather resistance, and is not prone to deformation after long-term use.

[0043] In an embodiment of the present application, preferably, an optical adhesive layer is arranged between the glass cover plate 5 and the color film 3, so that the color film 3 is bonded to one side surface of the glass cover plate 5 through the optical adhesive layer.

[0044] Specifically, when assembling the glass cover plate 5 and the color film 3, an optical adhesive layer is coated at a position of the glass cover plate 5 for mounting the color film 3, the color film 3 is attached to the position of the glass cover plate 5, and then the glass cover plate 5 is placed in a vacuum laminating machine, the laminating pressure is set to 0.6 MPa, the laminating time is set to 10 min, and the laminating temperature is set to 50°C, so that the glass cover plate 5 and the color film 3 are closely laminated.

[0045] At this time, the elastic plastic pad 2 arranged on the key plate frame 1 can absorb the deformation of the key plate frame 1, so as to provide stable pressure for the color film 3 and avoid the occurrence of light leakage due to the gap between the key plate frame 1 and the color film 3.

[0046] In this embodiment, preferably, the thickness of the optical adhesive layer is not less than 0.1 mm, so as to ensure the stability of the bonding between the color film 3 and the glass cover plate 5.

[0047] Preferably, the refractive index of the optical adhesive used in the optical adhesive layer is not greater than 1.5, the viscosity is not greater than 500 cP, and the hardness after curing is not greater than Shore D80, so as to ensure that the use of the optical adhesive layer will not affect the use feeling of the touch panel assembly.

[0048] In this embodiment, preferably, the thickness of the glass cover plate 5 is 3.5 mm-5.5 mm, the light transmittance of the glass cover plate 5 is not less than 90%, and the haze of the glass cover plate 5 is less than 1%, so that the touch panel assembly has good clarity and improves the user experience.

[0049] The present application also provides a kitchen electrical equipment comprising the touch panel assembly of any of the above embodiments.

[0050] In this embodiment, the kitchen electrical equipment comprises the touch panel assembly, so that the kitchen electrical equipment has all the beneficial effects of the touch panel assembly, which will not be repeated here.
