Description

Technical Field

[0001] The utility model relates to the technical field of glass products, in particular to a heatable glass panel. Background Art

[0002] Car defoggers are mainly achieved by increasing the windshield temperature or reducing the air humidity inside the car. Traditional methods include: 1. Warm air defogger: By turning on the car's heater system, hot air is blown towards the windshield, raising the glass surface temperature so that water vapor in the fog cannot condense into fog on the glass; or 2. Air conditioning cooling: Using the air conditioning cooling mode, the air temperature inside the car is quickly lowered, reducing the water vapor content in the air, thereby preventing the formation of fog; or 3. Air circulation: Through the car's internal and external circulation system, dry air outside is introduced into the car, reducing the air humidity inside the car and reducing the formation of fog. However, using the above methods requires a certain reaction time and cannot quickly defog the entire car glass, posing certain safety risks during driving.

[0003] In addition, in home appliances such as ovens, vending machines, and refrigerators, rapid demisting is also required to ensure that the glass surface remains clearly visible under various environmental conditions and improve user experience and safety.

[0004] To this end, the present invention proposes a heatable glass panel that can be used in a variety of scenarios. Utility Model Content

[0005] The purpose of this utility model is to solve the above shortcomings in the prior art. In order to achieve the above purpose, this utility model adopts the following technical solutions:

[0006] A heatable glass panel comprises a first glass layer and a second glass layer, wherein a heating layer is sandwiched between the first glass layer and the second glass layer;

[0007] The heating layer is adhered to the first glass layer, at least one silver paste heating line is led out from the edge of the heating layer, and a tongue piece is welded on the silver paste heating line in the direction toward the second glass layer;

[0008] The second glass layer is provided with a notch groove for fitting with the tongue;

[0009] During assembly, the first glass layer and the second glass layer are bonded together via a colloid layer.

[0010] Preferably, there are two silver paste heating lines, which are symmetrically printed on the left and right ends of the edge of the heating layer, so as to facilitate simultaneous heating on both sides, make demisting more uniform, and make the demisting effect faster.

[0011] Preferably, the tongue piece is externally connected to a power line, and after assembly, the tongue piece extends to the outside of the second glass layer to facilitate external wiring.

[0012] Preferably, the colloid layer is glued to the outer sides of the first glass layer and the second glass layer, so as to achieve an integrated glue-bonding effect.

[0013] Preferably, the heating layer is formed by mixing glass powder and graphite powder and then spraying the mixture onto one side surface of the first glass layer.

[0014] Preferably, the first glass layer and the second glass layer are the same or different and are selected from soda-lime silicate glass, aluminosilicate glass, lithium aluminosilicate glass or lithium aluminoborosilicate glass.

[0015] Preferably, the heatable glass panel mentioned in the above solution can be used on a vehicle windshield.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Mix glass powder and graphite powder and stir them thoroughly, then spray them on one side of the first glass layer to form a heating layer, so that the heat of the silver paste heating wire can be transferred to the first and second glass layers in a timely manner, achieving a defogging effect;

[0018] 2. By extending the tongue outward from the second glass layer, it is easier to better match the power line with the tongue, and the tongue is fixed to the silver paste heating wire of the first glass layer by welding to achieve the effect of power heating or signal transmission;

[0019] 3. By using the combination of silver paste heating wire, heating layer and tongue piece, the fog and frost on the glass can be quickly removed, and the visibility of the glass can be improved. Whether it is used in automobiles or home appliances, it improves customer sensory perception and improves product safety. In addition, the silver paste heating wire has a long service life and low maintenance cost. Therefore, the entire assembly solution is more energy-saving and environmentally friendly than the traditional heating and demisting method, reducing energy consumption and emissions.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0030] Reference Figure 1-Figure 3 A heatable glass panel includes a first glass layer 100 and a second glass layer 200, wherein a heating layer 101 is sandwiched between the first glass layer 100 and the second glass layer 200, and the heating layer 101 is formed by mixing glass powder and graphite powder and spraying the mixture onto one side of the first glass layer 100;

[0031] The heating layer 101 is adhered to the first glass layer 100, and at least one silver paste heating line 102 is extended from the edge of the heating layer 101. In this embodiment, there are two silver paste heating lines 102. Specifically, two silver paste heating lines 102 are symmetrically printed on the left and right ends of the edge of the heating layer 101, so as to achieve a uniform defogging effect.

[0032] The silver paste heating wire 102 is welded with a tongue 300 in the direction toward the second glass layer 200. After assembly, the tongue 300 extends outward from the second glass layer 200 and is connected to the power line. To facilitate the mating of the tongue 300 on the first glass layer 100 and the second glass layer 200, a notch 201 for plugging is provided on the second glass layer 200.

[0033] During assembly, the first glass layer 100 and the second glass layer 200 are bonded together by the colloid layer 400. In order to prevent the influence of heat conduction, see Figure 3 The colloid layer 400 is glued to the outer sides of the first glass layer 100 and the second glass layer 200;

[0034] In addition, in the selection of materials for the first glass layer 100 and the second glass layer 200, we choose the same or different materials selected from soda-lime silicate glass, aluminosilicate glass, lithium aluminosilicate glass or lithium aluminoborosilicate glass.

[0035] During assembly, the present invention first mixes glass powder and graphite powder in a certain proportion and then sprays the mixture on the surface of the first glass layer. Generally, in order to facilitate subsequent gluing, the sprayed portion is set on the inner side of the gluing position and filled. When the spraying is completed, a heating layer is formed on the first glass layer. Silver paste heating lines are symmetrically printed on both ends of the outer side of the heating layer. The first glass layer printed with the silver paste heating lines is then subjected to a tempering process. After the tempering is completed, the tongue piece is fixed on the silver paste heating line by welding. The welding needle and the tongue piece are in point contact. After assembly is completed, the edge of the first glass layer is coated with glass interlayer (colloid), and then the tongue piece is aligned with the notch of the second glass layer for mating, and finally, electrical heating or signal transmission is achieved.

[0036] When the utility model is in use, by turning on the power switch, the current passes through the tongue to make the silver paste heating wire heat up. After the silver paste heating wire heats up, the heat is conducted to the heating layer, thereby heating the first glass layer and the second glass layer, and finally realizing the heating and demisting function.

[0037] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
