Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a heating kettle. BACKGROUND

[0002] With the increasing demand for convenient drinking water and healthy life, heating kettles have become an indispensable small household appliance in modern families and office environments. Its core function is to quickly and safely heat cold water to the desired temperature to meet various needs such as drinking, tea brewing, and coffee brewing.

[0003] The kettle body of the traditional heating kettle is generally a structure combining a metal base plate and a glass kettle body. The metal base plate has fast heat conduction, and the glass kettle body is convenient for observing the situation inside the kettle. The metal base plate and the glass kettle body are generally connected by adhesive. The glue is exposed to the water body, which will release gas during the boiling process, resulting in poor taste of the water body, and these gases often have certain harm to the human body. Moreover, scale is prone to form at the bonding site, which is difficult to clean.

[0004] In the prior art, there are also some health care kettles / water boilers that use all-glass kettle bodies. However, due to the influence of the glass material, the kettle body is prone to breakage due to uneven heating. In this part of the scheme, once the kettle body breaks, there is a risk of water flowing into the lower heating control circuit. Therefore, the focus / difficulty of the all-glass kettle body scheme is to ensure uniform heat conduction of the kettle body and avoid kettle body breakage. SUMMARY

[0005] The present application provides a heating kettle to solve the technical problems of the prior art, such as the bottom of the all-glass kettle body being made of glass material and poor heat conduction.

[0006] In a first aspect, the embodiments of the present application provide a heating kettle, comprising: a kettle body made of all-glass material; a heating seat comprising a seat body and a heat source fixed in the seat body; the seat body is fixedly connected to the bottom of the kettle body, and the heat source faces the kettle bottom; a uniform heating layer arranged between the heat source and the kettle bottom; The uniform heating layer comprises: heat-conducting glue, glass fiber mesh or metal mesh; the heat-conducting glue is adhered to the kettle bottom; along the direction in which the heat source points to the kettle bottom, the glass fiber mesh is at least partially embedded in the heat-conducting glue, and the mesh holes of the glass fiber mesh are filled with heat-conducting glue. The glass fiber mesh is preferred. This is because the glass fiber mesh not only has good heat conduction and heat resistance, but also can confine the glue in the mesh holes and avoid large cracks in the glue. Moreover, the glass fiber mesh can also squeeze the air bubbles in the glue, allowing the gas in the glue to be discharged through the glass fiber, and the price is also affordable.

[0007] In some embodiments, the thermally conductive adhesive and the glass fiber mesh or metal mesh are both disc-shaped and their centers coincide along the thickness direction; the overlapping area of ​​the outer contour areas of the thermally conductive adhesive and the glass fiber mesh or metal mesh is not less than 95% of the area of ​​the thermally conductive adhesive.

[0008] In some embodiments, the thickness of the fiberglass mesh is less than the thickness of the thermally conductive adhesive; On the side of the heat spreader away from the bottom of the pot, the glass fiber mesh or metal mesh is flush with the thermally conductive adhesive.

[0009] In some embodiments, the heating kettle further includes: a microcrystalline glass plate or a metal plate; A microcrystalline glass plate or a metal plate is disposed between the heat source and the heat spreader, with one side facing the heat source and the other side bonded to the heat spreader. Preferably, the metal plate is an aluminum plate.

[0010] In some embodiments, the heating base further includes: a first support and a heat transfer element; The first bracket is fixed in the base body, and the top of the first bracket supports a microcrystalline glass plate or a metal plate. The heat transfer component is bowl-shaped with a hollow bottom and has a first contact portion and a second contact portion at an angle to each other; the first contact portion is parallel to the bottom of the pot and the second contact portion extends toward the pot body. The first contact portion is pressed against the bottom of the first support and connected to the microcrystalline glass plate or metal plate through a connector passing through the first support; the second contact portion surrounds the first outer periphery of the bottom of the pot. The aforementioned heat transfer component creates a temperature gradient at the bend (the most vulnerable part) of the outer periphery of the glass pot, preventing the glass pot from cracking.

[0011] In some embodiments, the heat source includes: First heating plate; The first support is hollow, and the first heating plate is set in the hollow area of ​​the first support, facing the microcrystalline glass plate or metal plate; On the bottom of the kettle, there is a gap between the orthographic projection range of the first contact portion and the orthographic projection range of the first heating plate.

[0012] In some embodiments, the heating base further includes a second support; The second support is mounted on the seat; the side of the second support facing the inside of the seat is fixedly connected to the end of the second contact part away from the first contact part by a buckle. The bottom outer circumference of the pot body has a stepped structure; the stepped structure is fixedly erected on the second support.

[0013] In some embodiments, the heat source includes: The heating element is housed within the base; the heating element has a receiving cavity. The heating element is located at the bottom of the accommodating cavity; The heat spreader is placed at the opening of the cavity, and there is a gap between the heating element and the heat spreader.

[0014] In some embodiments, the heating element includes at least one of a heating wire, a heating element, and a heating tube.

[0015] In some embodiments, the heat source includes: a second heating plate; The second heating plate is attached to the side of the heat spreader away from the bottom of the pot.

[0016] The heating kettle provided in this application has the following technical advantages: This application involves attaching a heat-dissipating layer to the outer surface of the bottom of a glass teapot. This layer possesses excellent internal thermal conductivity, enabling it to rapidly diffuse concentrated and uneven heat from the heat source and conduct it to the bottom of the teapot. This reduces temperature differences across different areas of the bottom, preventing breakage caused by uneven temperature distribution. The heat-dissipating layer comprises thermally conductive adhesive and a fiberglass mesh or metal mesh. Its excellent thermal conductivity allows for lateral heat conduction through the fiberglass mesh or metal mesh when there is localized temperature unevenness, preventing localized overheating. The fiberglass mesh or metal mesh also confines some of the thermally conductive adhesive within its pores, partially reducing tension between the adhesive particles and mitigating cracking. This prevents large cracks in the thermally conductive adhesive and ensures its excellent heat-dissipating properties. Furthermore, after applying the thermally conductive adhesive to the bottom of the kettle, this application presses a glass fiber mesh into the adhesive. During the pressing process, air bubbles or gases can escape along the mesh fibers, thereby reducing air bubbles in the adhesive and improving its heat dissipation performance. Additionally, even if the kettle body cracks, the heat dissipation layer in this application can still hold the water at the bottom, preventing spilled water from flowing into the heating control circuit below.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0023] The research and development concept of this application includes: The all-glass kettle body requires extremely high heat uniformity. Thermally conductive adhesive is typically applied to the bottom of the kettle body in a liquid state before the kettle is installed on the base. During the curing process, the thermally conductive adhesive is prone to cracking or the presence of air bubbles due to stress changes and the gas it generates. Cracks in the thermally conductive adhesive prevent effective heat conduction, resulting in uneven temperatures in different areas and a large temperature difference, which can easily lead to cracking and breakage of the glass kettle body. Similarly, the presence of air bubbles can also cause poor local heat transfer, resulting in localized high temperatures. This application incorporates a heat-equalizing layer to improve upon these shortcomings of the thermally conductive adhesive.

[0024] This application provides a heating kettle, the structural schematic diagram of which is shown below. Figures 1-9 As shown, the heating kettle includes: kettle body 100, heating base 200 and heat spreader 300.

[0025] The body of the kettle is made entirely of glass.

[0026] The heating base 200 includes a base body 210 and a heat source 220 fixed inside the base body 210; the base body 210 is fixedly connected to the bottom of the kettle body 100, and the heat source 220 faces the bottom 110 of the kettle body 100.

[0027] A heat spreader layer 300 is disposed between the heat source 220 and the bottom of the kettle 110. The heat spreader layer 300 includes: thermally conductive adhesive 310, fiberglass mesh 320 or metal mesh 320; wherein, fiberglass mesh 320 is preferred. The thermally conductive adhesive 310 is adhered to the bottom of the kettle 110; along the direction from the heat source 220 to the bottom of the kettle 110, the fiberglass mesh 320 or metal mesh 320 is at least partially embedded in the thermally conductive adhesive 310, and the mesh openings of the fiberglass mesh 320 or metal mesh 320 are filled with thermally conductive adhesive 310.

[0028] In this embodiment, as Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the heated kettle after the kettle body 100 is concealed. A heat-dissipating layer 300 is attached to the outer surface of the bottom 110 of the all-glass kettle body 100. The heat-dissipating layer 300 has good internal heat conduction properties, which can quickly diffuse the concentrated and uneven heat from the heat source 220 and conduct it to the bottom 110 of the kettle body 100, reducing the temperature difference between different areas of the bottom 110 of the kettle body 100, and avoiding damage caused by uneven temperature distribution at the bottom 110. For example, Figures 4-9As shown, the heat spreader 300 includes thermally conductive adhesive 310 and a fiberglass mesh 320 or a metal mesh 320. The fiberglass mesh 320 or the metal mesh 320 has a mesh structure and good thermal conductivity. When the local temperature is uneven, heat can be conducted within the fiberglass mesh 320 or the metal mesh 320, preventing the generation of local high temperatures. Moreover, the fiberglass mesh 320 or the metal mesh 320 can confine part of the thermally conductive adhesive 310 within the mesh openings, which can to a certain extent block the tension between the thermally conductive adhesive 310, thereby reducing the cracking phenomenon of the thermally conductive adhesive 310, preventing the formation of large-sized cracks in the thermally conductive adhesive 310, and ensuring the good heat spreader performance of the thermally conductive adhesive 310 itself.

[0029] Furthermore, considering that the thermally conductive adhesive 310 will evaporate and generate bubbles during the coating process on the bottom 110 of the kettle, and that these bubbles will block the heat conduction of the thermally conductive adhesive 310, in this embodiment, after the thermally conductive adhesive 310 is coated on the bottom 110 of the kettle, a glass fiber mesh 320 or a metal mesh 320 is pressed into the thermally conductive adhesive 310. During the pressing process, bubbles or gas can escape along the mesh fibers of the glass fiber mesh 320 or the metal mesh 320, thereby reducing the number of bubbles in the thermally conductive adhesive 310 and improving the heat dissipation performance of the thermally conductive adhesive 310.

[0030] Optionally, the fiberglass mesh 320 is a mesh material made by weaving fiberglass yarn as the base material.

[0031] Optionally, the base 210 has a receiving area, and a heat source 220 is disposed in the receiving area. The heat source 220 is exposed through the opening of the receiving area and faces the bottom 110 of the pot body 100.

[0032] In some embodiments, the thermally conductive adhesive 310 and the glass fiber mesh 320 or metal mesh 320 are both disc-shaped and their centers coincide along the thickness direction; the overlapping area of ​​the outer contour areas of the thermally conductive adhesive 310 and the glass fiber mesh 320 or metal mesh 320 is not less than 95% of the area of ​​the thermally conductive adhesive 310.

[0033] In this embodiment, along the thickness direction of the thermally conductive adhesive 310, the glass fiber mesh 320 or metal mesh 320 is at least partially embedded within the thermally conductive adhesive 310. The thermally conductive adhesive 310 and the glass fiber mesh 320 or metal mesh 320 have approximately the same planar dimensions and are overlapped. Therefore, the glass fiber mesh 320 or metal mesh 320 can confine as much of the plane of the thermally conductive adhesive 310 as possible, thereby improving the heat dissipation effect of the entire heat-spreading layer 300.

[0034] In some embodiments, the thickness of the glass fiber mesh 320 or the metal mesh 320 is less than the thickness of the thermally conductive adhesive 310.

[0035] On the side of the heat spreader 300 away from the bottom of the pot 110, the fiberglass mesh 320 or metal mesh 320 is flush with the thermally conductive adhesive 310.

[0036] In this embodiment, along the thickness direction of the thermally conductive adhesive 310, the glass fiber mesh 320 or metal mesh 320 is embedded in the thermally conductive adhesive 310 and flush with the thermally conductive adhesive 310. Therefore, both the glass fiber mesh 320 or metal mesh 320 and the thermally conductive adhesive 310 can contact the heat source 220. The heat from the heat source 220 can be diffused through the glass fiber mesh 320 or metal mesh 320 and the thermally conductive adhesive 310, thereby improving the heat dissipation effect of the entire heat dissipation layer 300.

[0037] In some embodiments, the glass fiber mesh 320 or the metal mesh 320 is embedded in the thermally conductive adhesive 310, so that both sides of the glass fiber mesh 320 or the metal mesh 320 have continuous thermally conductive adhesive 310, thereby making the thermally conductive adhesive 310 more continuous and ensuring the reliability of the thermally conductive adhesive 310.

[0038] Considering that modern electric kettles generally have a long-term heat preservation function, which requires a long-term heating function to maintain, prolonged heating may cause the temperature of the heat spreader 300 to rise continuously, thereby causing the temperature of the kettle body 100 to rise continuously, reaching the tolerance threshold of the kettle body 100 and thus damaging it. Therefore, in some embodiments, please refer to... Figure 4 and Figure 5 The heating pot also includes: a microcrystalline glass plate 400 or a metal plate 400.

[0039] A microcrystalline glass plate 400 or a metal plate 400 is disposed between the heat source 220 and the heat spreader 300, with one side facing the heat source 220 and the other side being bonded to the heat spreader 300.

[0040] In this embodiment, the microcrystalline glass plate 400 or the metal plate 400 is disposed between the heat source 220 and the heat spreader 300. The microcrystalline glass plate 400 or the metal plate 400 can absorb a small amount of infrared energy and thus heat up, creating a temperature difference on both sides of the microcrystalline glass. In other words, the microcrystalline glass plate 400 or the metal plate 400 can play a certain heat-insulating effect, preventing the heat spreader 300 from getting too hot, thereby protecting the heat spreader 300, reducing the risk of cracking of the thermally conductive adhesive 310, and also protecting the kettle body 100.

[0041] Since the pot body 100 is made entirely of glass, a bend 130 is provided at the connection between the first outer periphery 120 and the bottom 110 at the bottom of the pot body 100. However, the bend 130 has poor durability and is prone to cracking under large temperature differences. Therefore, in some embodiments, please refer to... Figure 4 and Figure 5 The heating base 200 also includes a first support 230 and a heat transfer element 240.

[0042] The first bracket 230 is fixed inside the base 210, and the top of the first bracket 230 supports the microcrystalline glass plate 400 or the metal plate 400.

[0043] The heat transfer element 240 is bowl-shaped with a hollow bottom and has a first contact portion 241 and a second contact portion 242 at an angle to each other; the first contact portion 241 is parallel to the bottom of the pot 110 and the second contact portion 242 extends toward the pot body 100.

[0044] The first contact portion 241 is pressed onto the bottom of the first bracket 230 and connected to the microcrystalline glass plate 400 or the metal plate 400 through the connector 260 passing through the first bracket 230; the second contact portion 242 surrounds the first outer periphery 120 of the bottom of the pot body 100.

[0045] In this embodiment, the first support 230 is fixedly disposed within the base 210. A microcrystalline glass plate 400 or a metal plate 400 is disposed on the first support 230. The first contact portion 241 of the heat transfer element 240 is pressed against the first support 230. A connector 260 passes through the first support 230, connecting the microcrystalline glass plate 400 or the metal plate 400 on the first support 230 and the first contact portion 241 under the first support 230, allowing heat from the microcrystalline glass plate 400 or the metal plate 400 to pass through... The connector 260 reaches the heat transfer element 240, which surrounds the first outer periphery 120 of the bottom of the kettle body 100 and the bent portion 130 between the first outer periphery 120 and the bottom of the kettle 110. The bowl-shaped heat transfer element 240 can form a heat preservation zone, thereby making the temperature between the first outer periphery 120 and the bottom of the kettle body 100 close. This reduces the possibility of cracking at the bend due to the large temperature difference, and improves the reliability and service life of the all-glass kettle body 100.

[0046] Optionally, the first support 230 has a stud, and the connector 260 is a screw disposed inside the stud. The two ends of the screw are connected to the first contact portion 241 of the microcrystalline glass plate 400 or metal plate 400 and the heat transfer element 240.

[0047] Optionally, the heat transfer element 240 is made of aluminum.

[0048] Next, this application provides three different embodiments of the heating kettle with different structures.

[0049] Firstly, please refer to Figure 4 and Figure 5In the heating kettle, the heat source 220 includes a first heating plate 221. A first support 230 is hollow, and the first heating plate 221 is disposed within the hollow area of ​​the first support 230, facing the microcrystalline glass plate 400 or the metal plate 400. On the bottom 110 of the kettle, the projected area of ​​the first contact portion 241 is spaced from the projected area of ​​the first heating plate 221.

[0050] In this embodiment, the heat transfer element 240 only needs to perform the function of heat transfer. The cleverly designed annular heat transfer element 240 provides space for the first heating plate 221, allowing the first heating plate 221 to be placed inside the annular heat transfer element 240. Moreover, the first support 230 has a certain thickness. The first heating plate 221, located in the hollow area of ​​the first support 230, is fixed to the bottom of the first support 230 and has a gap with the microcrystalline glass plate 400 or metal plate 400 above the first support 230. An air medium layer is formed between the first heating plate 221 and the microcrystalline glass plate 400 or metal plate 400. The air conducts the heat of the first heating plate 221 to the microcrystalline glass plate 400 or metal plate 400, avoiding direct contact between the first heating plate 221 and the microcrystalline glass plate 400 or metal plate 400, thus reducing the possibility of damage to the microcrystalline glass plate 400 or metal plate 400 due to direct contact.

[0051] Furthermore, the heating base 200 also includes: a second support 250; the second support 250 is partially mounted on the base 210; the side of the second support 250 facing the inside of the base 210 is fixedly connected to the end of the second contact portion 242 away from the first contact portion 241 by a snap fastener; the bottom outer periphery of the kettle body 100 has a stepped structure; the stepped structure is fixedly mounted on the second support 250.

[0052] In this embodiment, the second support 250 is also ring-shaped and rests on the opening of the base 210, exposing the microcrystalline glass plate 400 or the metal plate 400. The bottom of the kettle body 100 has a multi-segment structure with different diameters, forming a stepped structure on the outer periphery of the bottom of the kettle body 100. The stepped structure is ring-shaped and fixedly rests on the ring-shaped second support 250. The stepped structure provides sufficient space for fixing the kettle body 100, making the connection between the stepped structure and the base 210 stable. Moreover, the second support 250, in addition to fixing the kettle body 100, also serves to fix the heat transfer component 240.

[0053] Other technical features, such as the heat spreader 300, have been described above in this embodiment and will not be repeated here. Only the parts that are different from the aforementioned embodiments are described here. Those skilled in the art can understand that the technical features in other embodiments of this application can be freely combined with the features in this embodiment.

[0054] Secondly, please refer to Figure 6 and Figure 7In the heating kettle, the heat source 220 includes a heating element 222 and a heating element 223. The heating element 222 is disposed in the base 210; the heating element 222 has a receiving cavity; the heating element 223 is disposed at the bottom of the receiving cavity; the heat spreader 300 is laid at the opening of the receiving cavity, and there is a gap between the heating element 223 and the heat spreader 300.

[0055] Unlike the previous embodiment, in the heat source 220 of this embodiment, the heating element 222 houses the heating element 223, which has the effect of protection and heat preservation. The heating element 223 inside the heating element 222 is located at the bottom of the heating element 222, and the pot body 100 is located above the heating element 222, so that there is a gap between the heat spreader 300 connected to the bottom 110 of the pot body 100 and the heating element 223. An air medium layer is formed between the heat spreader 300 and the heating element 223. The air conducts the heat of the heating element 223 to the heat spreader 300, avoiding direct contact between the heating element 223 and the heat spreader 300, and reducing the possibility of damage to the heat spreader 300 due to direct contact.

[0056] Furthermore, the heating element 223 includes at least one of a heating wire, a heating plate, and a heating tube.

[0057] In this embodiment, the heating element 223 can be a heating wire, a heating element, or a heating tube, or it can be a combination of at least two of the three, providing heat.

[0058] Other technical features, such as the heat spreader 300, have been described above in this embodiment and will not be repeated here. Only the parts that are different from the aforementioned embodiments are described here. Those skilled in the art can understand that the technical features in other embodiments of this application can be freely combined with the features in this embodiment.

[0059] Thirdly, please refer to Figure 8 and Figure 9 In the heating pot, the heat source 220 includes: a second heating plate 224; the second heating plate 224 is attached to the side of the heat equalization layer 300 away from the bottom 110 of the pot.

[0060] Unlike the previous embodiment, in this embodiment, the heat source 220 directly adopts a disc-shaped first heating plate 221, which is attached to the side of the heat equalization layer 300 away from the bottom of the pot 110, and directly heats the heat equalization layer 300. The disc-shaped first heating plate 221 itself has a good heat equalization effect, and by directly attaching to the heat equalization layer 300, it evenly conducts heat to the bottom of the pot 110 of the pot body 100.

[0061] Other technical features, such as the heat spreader 300, have been described above in this embodiment and will not be repeated here. Only the parts that are different from the aforementioned embodiments are described here. Those skilled in the art can understand that the technical features in other embodiments of this application can be freely combined with the features in this embodiment.

[0062] By applying the embodiments of this application, at least the following beneficial effects can be achieved: (1) A heat-spreading layer 300 is attached to the bottom 110 of the all-glass pot body 100. The heat-spreading layer 300 has good internal thermal conductivity and can quickly diffuse the concentrated and uneven heat from the heat source 220 and conduct it to the bottom 110 of the pot body 100, reducing the temperature difference between different areas of the bottom 110 of the pot body 100 and avoiding damage caused by uneven temperature distribution of the bottom 110. The heat-spreading layer 300 includes thermally conductive adhesive 310 and glass fiber mesh 320 or metal mesh 320. The glass fiber mesh 320 or metal mesh 320 has a mesh structure and good thermal conductivity. When the local temperature is uneven, heat can be conducted laterally inside the glass fiber mesh 320 or metal mesh 320 to prevent the generation of local high temperature. Moreover, the fiberglass mesh 320 or metal mesh 320 can confine some of the thermally conductive adhesive 310 within the mesh openings, which can block the tension between the thermally conductive adhesive 310 to a certain extent, thereby reducing the cracking phenomenon of the thermally conductive adhesive 310, reducing the possibility of large-sized cracks, and ensuring the good heat dissipation performance of the thermally conductive adhesive 310 itself.

[0063] (2) Considering that during the process of applying thermally conductive adhesive 310 to the bottom of the kettle 110, the thermally conductive adhesive 310 will evaporate and generate bubbles, and the bubbles will block the heat conduction of the thermally conductive adhesive 310. Therefore, in this embodiment, after the thermally conductive adhesive 310 is applied to the bottom of the kettle 110, the glass fiber mesh 320 is pressed into the thermally conductive adhesive 310. During the pressing process of the thermally conductive adhesive 310, bubbles or gas can escape along the mesh of the glass fiber mesh 320, thereby reducing the bubbles in the thermally conductive adhesive 310 and improving the heat uniformity of the thermally conductive adhesive 310.

[0064] (3) Along the thickness direction of the thermally conductive adhesive 310, the glass fiber mesh 320 or metal mesh 320 is at least partially embedded in the thermally conductive adhesive 310. The thermally conductive adhesive 310 and the glass fiber mesh 320 or metal mesh 320 have approximately the same planar dimensions and are overlapped. Therefore, the glass fiber mesh 320 or metal mesh 320 can confine as much of the plane of the thermally conductive adhesive 310 as possible, thereby improving the heat dissipation effect of the entire heat dissipation layer 300.

[0065] (4) The microcrystalline glass plate 400 or the metal plate 400 is placed between the heat source 220 and the heat spreader 300. The microcrystalline glass plate 400 or the metal plate 400 can absorb a small amount of infrared energy and thus heat up, so that a temperature difference is formed on both sides of the microcrystalline glass. That is, the microcrystalline glass plate 400 or the metal plate 400 can play a certain heat insulation effect, prevent the heat spreader 300 from being too hot, and thus protect the heat spreader 300, reduce the risk of cracking of the thermal adhesive 310, and also protect the kettle body 100.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
