Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an all-glass heating kettle. Background Technology

[0002] Glass kettles are a common household appliance, widely used due to their advantages such as being transparent and aesthetically pleasing, and allowing for easy observation of the water's condition.

[0003] Common glass kettles mainly include electric heating glass kettles, constant temperature glass kettles, multi-functional glass kettles, and electroplated glass kettles. Most electric heating kettles use an electric heating element installed at the bottom, converting electrical energy into heat to heat the water. To reduce leaks or short circuits, some electric heating kettles use a separate heating element, where the heating plate is mounted on a base and can be sealed. When heating water, the kettle is placed on the heating plate so that the heat generated by the heating element is transferred to the inside of the glass kettle. However, the heat transfer efficiency between the glass kettle and the heating plate is poor, resulting in long boiling times, wasted energy, and a higher risk of breakage due to the hard contact between the bottom of the glass kettle and the heating plate during long-term use.

[0004] Therefore, those skilled in the art are dedicated to developing an all-glass heating kettle to improve the heat transfer efficiency between the glass kettle and the heating base plate and reduce the risk of glass kettle breakage. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an all-glass heating kettle that improves the heat transfer efficiency between the glass kettle and the heating base plate and reduces the risk of glass kettle breakage.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A fully glass kettle includes a glass kettle body with a flat bottom surface having a flatness tolerance of 0.02 mm to 0.1 mm. The bottom surface is coated with a heat-conducting layer having a thickness of 0.2 mm to 0.5 mm.

[0008] The beneficial effects of this utility model are: by coating the bottom surface of the glass kettle body with a heat-conducting layer, the heat transfer efficiency between the glass kettle and the heating plate can be significantly improved. The addition of the heat-conducting layer, as a heat conduction medium, helps heat to be transferred from the heating plate to the glass kettle more quickly, thereby reducing boiling time and improving energy utilization efficiency.

[0009] The flatness tolerance of the bottom surface of the glass water bottle is controlled between 0.02mm and 0.1mm. This high-precision processing technology can ensure good contact between the bottom surface of the glass water bottle and the heating plate, reduce the risk of breakage caused by hard impact, and enhance the durability and service life of the glass water bottle.

[0010] The thickness of the thermal conductive layer is controlled between 0.2mm and 0.5mm. This thickness range ensures the thermal conductivity while avoiding damage caused by excessive thinness and reduced heat transfer efficiency caused by excessive thickness, thereby improving safety during use.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the thermally conductive layer is made of a high-temperature resistant ink coating with thermally conductive metal powder, or thermally conductive silicone, or graphene.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the heat-conducting layer is made of high-temperature resistant ink coating with heat-conducting metal powder, or heat-conducting silicone, or graphene, which can efficiently conduct the heat emitted by the heating base plate to the glass kettle body, achieving the purpose of rapid water boiling and energy saving. At the same time, the heat-conducting layer separates the bottom of the glass kettle from the heating base plate, and the heat-conducting layer has a certain elasticity and toughness, which plays a buffering role and can effectively protect the glass kettle and prevent it from breaking.

[0014] Furthermore, an asbestos mesh layer is also provided in the middle of the heat-conducting layer.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the asbestos mesh layer helps to evenly transfer heat to the bottom surface, avoiding uneven heating of the bottom surface and the occurrence of cracks or deformation.

[0016] Furthermore, the glass kettle body includes a glass kettle body, the bottom surface is connected to the lower side of the glass kettle body, and the spout is also provided on the upper side of the glass kettle body.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the spout facilitates the pouring of liquid from the glass pitcher.

[0018] Furthermore, the glass body is made of borosilicate glass, and the bottom surface is made of microcrystalline glass.

[0019] The beneficial effects of adopting the above-mentioned further solutions are: microcrystalline glass reduces cracking, and high borosilicate glass increases the strength of the glass pot body.

[0020] Furthermore, a handle is also installed on the glass water bottle body.

[0021] The advantage of adopting the above-mentioned further solution is that the handle makes it easier to hold and move the glass heating pot.

[0022] Furthermore, a temperature sensor is also installed on the bottom surface. The detection end of the temperature sensor is located at the bottom of the bottom surface, and a shielding layer is provided on the outside of the temperature sensor. The end of the temperature sensor and the side opposite to the bottom surface have a signal conduction part.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the sensor is used to detect the temperature inside the glass heating kettle, and the temperature detection information is transmitted to the heating component controller through the conductive part.

[0024] Furthermore, a glass lid is also installed on the glass water bottle body.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the glass lid reduces the amount of impurities entering the glass water bottle.

[0026] Furthermore, the glass cover includes a disc portion and a cylindrical portion. The lower side of the disc portion abuts against the upper end of the glass water bottle body, and the cylindrical portion is located at the mouth of the glass water bottle body. A filter funnel is also installed inside the cylindrical portion.

[0027] The beneficial effect of adopting the above-mentioned further solution is that the filter basket is used to store and filter tea leaves.

[0028] Furthermore, a magnetic sensor that cooperates with the heating base plate detection part is also installed on the lower side of the bottom surface, and the magnetic sensor is located in the middle of the bottom surface.

[0029] The beneficial effect of adopting the above-mentioned further solution is that the magnetic sensor is used to detect whether the glass kettle is placed on the heating element. Attached Figure Description

[0035] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0036] In the description of this utility model, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "inner", "outer", "circumferential", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, an all-glass kettle includes a glass kettle body 1 with a flat bottom surface 2. The flatness tolerance of the bottom surface 2 is 0.02 mm to 0.1 mm. The bottom surface 2 is coated with a heat-conducting layer 3 with a thickness of 0.2 mm to 0.5 mm. The addition of the heat-conducting layer 3 acts as a heat conduction medium, helping heat to be transferred more quickly from the heating plate to the inside of the glass kettle, thereby reducing boiling time and improving energy efficiency.

[0040] In the embodiments, the thermally conductive layer 3 is made of a high-temperature resistant ink coating with thermally conductive metal powder, or thermally conductive silicone, or graphene.

[0041] Specifically, when using a high-temperature resistant ink coating, the bottom surface of the glass vessel is first wet-polished to ensure a flatness tolerance of approximately 0.02mm to 0.1mm. This step can be achieved by continuously dripping water onto the surface of a high-speed rotating grinding wheel, while the bottom of the glass is pressed against the grinding wheel surface manually or by a robotic arm to achieve the required flatness tolerance. After wet-polishing and cleaning the bottom surface of the glass heating container, the surface is cleaned with water and alcohol to remove any residual abrasive or impurities. Next, a high-temperature resistant paint layer containing thermally conductive metal powder is applied to the cleaned glass bottom surface using screen printing. Screen printing is a commonly used coating technique, and the uniformity and thickness of the coating can be controlled by adjusting the mesh count of the printing screen. High-temperature resistant ink containing thermally conductive metal powder is selected as the coating material, where the thermally conductive metal powder can be aluminum powder or copper powder, etc. The high-temperature resistant paint can be commercially available, with the thermally conductive metal powder added to enhance its thermal conductivity. Finally, the printed glass heating container blank needs to be baked and cured at high temperature to obtain the requirements of high wear resistance and high adhesion. The curing process is usually carried out in a high-temperature oven (furnace) above 500℃, and the curing time is about 60 minutes.

[0042] When using a thermally conductive silicone layer, after the initial thermally conductive silicone is preliminarily dried, use a 250-500 mesh screen to screen print the thermally conductive silicone on the bottom surface of the glass heating pot to make uneven areas smooth and meet the flatness tolerance requirements. Place the glass bottom surface coated with thermally conductive silicone into a high-temperature oven or furnace at about 200℃ to bake and cure.

[0043] When graphene is used as the heat-conducting layer 3, the graphene layer is attached to the bottom surface 2 and then directly fired into shape, or the graphene layer is directly pasted onto the bottom surface 2. The all-glass kettle absorbs heat from the heating base plate (electric ceramic stove, electric heating aluminum plate, etc., not shown in the figure) through heat conduction to heat the liquid in the kettle. Due to the influence of the contact area between the bottom of the glass kettle and the heating base plate and the flatness of the bottom of the glass kettle, the heat conduction efficiency is not ideal. After applying a layer of high thermal conductivity coating to the bottom of the glass kettle, the heat-conducting layer 3 can efficiently absorb heat from the heating base plate. At the same time, since the heat-conducting layer 3 is tightly integrated with the glass kettle, the two can achieve efficient heat transfer, and thus achieve efficient heat transfer from the heating base plate to the glass kettle through a relay method.

[0044] Glass is a brittle material and is easily broken when subjected to external impact. During long-term use, slight collisions and friction between the bottom of the glass kettle and the heating plate can also cause micro-cracks to form on the bottom of the kettle, which can then expand and lead to breakage. The heat-conducting layer 3 separates the bottom of the glass kettle from the heating plate, and the coating has a certain degree of elasticity and toughness, which acts as a buffer and can effectively protect the glass kettle and prevent it from breaking.

[0045] To further improve the uniform thermal conductivity of the thermal conductive layer 3, an asbestos mesh layer 4 is also provided in the middle of the thermal conductive layer 3.

[0046] like Figure 1 , Figure 2 As shown, in some embodiments, the glass kettle body 1 includes a glass body 5. A bottom surface 2 is connected to the lower side of the glass body 5 via high-temperature glass welding. A spout 6 is also present on the upper side of the glass body 5. The glass body 5 is made of high borosilicate glass, which has a low coefficient of thermal expansion, approximately one-third that of ordinary glass. This makes it less prone to breakage during rapid temperature changes, exhibiting stronger fracture resistance and resisting shattering under sudden temperature changes from 0℃ to 200℃. It also possesses high transparency. The bottom surface 2 is made of microcrystalline glass, which has high hardness and strength, is more wear-resistant and less prone to breakage than ordinary glass, has excellent light transmittance, good flatness and clarity, and strong processing performance.

[0047] The glass kettle body 1 is also equipped with a handle 7, which makes it easy to hold and move the heated kettle.

[0048] like Figure 1 , Figure 2 As shown, in one embodiment, a temperature sensor 8 is also installed on the bottom surface 2. The detection end of the temperature sensor 8 is located at the bottom of the bottom surface 2 and a shielding layer is provided on the outside of the temperature sensor 8. The end of the temperature sensor 8 and the side opposite to the bottom surface have a signal conduction part. The temperature sensor 8 is used to detect the temperature of the liquid in the heating kettle and transmit the temperature information to the controller of the heating component (not shown in the figure), so that the controller can control the heating rate of the heating component.

[0049] A magnetic sensor 13, which works in conjunction with the detection unit of the heating base plate, is also installed on the lower side of the bottom surface 2, and the magnetic sensor 13 is located in the middle of the bottom surface 2. When the heating base plate detects the magnetic sensor 13, it indicates that the kettle has been placed on the heating base plate, thus preventing the heating base plate from burning dry. Example

[0050] like Figure 1 , Figure 2 and Figure 3As shown, the difference between Embodiment 2 and Embodiment 1 is that a glass lid 9 is also installed on the glass kettle body 1. Specifically, the glass lid 9 includes a disc portion 10 and a cylindrical portion 11. The lower side of the disc portion 10 abuts against the upper end of the glass kettle body 1, and the cylindrical portion 11 is located at the mouth of the glass kettle body 1. A high-temperature resistant elastic sealing ring can also be installed on the outer layer of the cylindrical portion 11. A filter funnel 12 is also installed inside the cylindrical portion 11. The cylindrical portion 11 has a cavity in the middle and a hole at the bottom. The filter funnel 12 is installed inside the cavity and is used to fill tea leaves, etc. The cylindrical portion 11 and the disc portion 10 are detachably connected. When brewing, after removing the cylindrical portion 11 from the disc portion 10, tea leaves, etc. are placed in the filter funnel 12, and then the cylindrical portion 11 is fastened or threaded onto the disc portion 10.
