Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a liquid heating container. Background Technology
[0002] Existing liquid heating containers are typically used to heat liquids. Taking electric kettles as an example, electric kettle inner tanks generally have problems such as loud boiling noise, spots easily forming on the bottom after prolonged heating, and difficulty in cleaning. In addition, some inner tanks with large arc-shaped bottom walls also have the problem of poor stability when boiling water. The center of gravity of the water in the inner tank with a large arc-shaped bottom wall will be higher in the product. After the water boils and rolls in the inner tank, the product will shake more significantly due to the high center of gravity, which may lead to product tipping and safety risks. Furthermore, the water holding capacity of the inner tank with a large arc-shaped bottom wall is also reduced. Utility Model Content
[0003] The main objective of this invention is to provide a liquid heating container that addresses at least one of the technical problems mentioned in the background section.
[0004] To achieve the above objectives, the present invention proposes a liquid heating container, which includes an inner liner, a heat-conducting component, and a heating assembly. The inner liner includes a peripheral wall, a bottom wall, and a connecting wall connecting the peripheral wall and the bottom wall. The bottom wall extends radially along the inner liner, and the connecting wall is arc-shaped. The heat-conducting component is disposed on the outer surface of the bottom of the inner liner. The heating assembly includes a first heating element and a second heating element, both of which are disposed on the surface of the heat-conducting component away from the inner liner and are spaced apart in the axial direction of the inner liner.
[0005] In one embodiment, the heat-conducting component includes a first heat-conducting portion and a second heat-conducting portion connected to each other. The first heat-conducting portion is located inside the second heat-conducting portion. The first heat-conducting portion is used to fit against the bottom wall, and the second heat-conducting portion is used to fit against the connecting wall. The first heating element and the second heating element are disposed on the outer surface of the second heat-conducting portion, and the first heating element is located inside the second heating element.
[0006] In one embodiment, the first heating element has a first opening formed at its two ends at a distance, and the second heating element has a second opening formed at its two ends at a distance, wherein the first opening and the second opening have different orientations.
[0007] In one embodiment, the orientation of the first opening and the orientation of the second opening are opposite.
[0008] In one embodiment, the diameter of the bottom wall is D1, and the diameter of the peripheral wall is D2, satisfying 1 > D1 / D2 > 0.5.
[0009] In one embodiment, D1 and D2 satisfy 0.65 > D1 / D2 > 0.5.
[0010] In one embodiment, in the axial direction of the inner liner, the height of the connecting wall is H1, and the height of the heat-conducting element is H2, satisfying H1 > H2 > H1 / 2.
[0011] In one embodiment, in the axial direction of the inner liner, the shortest distance between the heating assembly and the end of the heat-conducting element is L1, which satisfies L1≥8mm.
[0012] In one embodiment, in the axial direction of the inner liner, the distance between the first heating element and the second heating element is L2, which satisfies 30mm≥L2≥5mm.
[0013] In one embodiment, the diameter of the bottom wall is D1, and the height of the connecting wall is H1, satisfying D1≥H1.
[0014] In one embodiment, the second heat-conducting part is provided with a plurality of strip-shaped notches, which are arranged at intervals along the circumference of the second heat-conducting part.
[0015] In one embodiment, the side of the heat-conducting component that is in contact with the inner liner is provided with a plurality of first grooves arranged at intervals along the circumference of the heat-conducting component, the first grooves being formed in the first heat-conducting portion and the second heat-conducting portion; and / or, the first heat-conducting portion is provided with a plurality of second grooves arranged at intervals along its circumference.
[0016] The technical solution of this utility model, by setting the inner liner to include a peripheral wall, a bottom wall, and a connecting wall connecting the peripheral wall and the bottom wall, with the bottom wall extending radially along the inner liner, facilitates cleaning of the inner liner. Compared to the traditional large arc-shaped bottom wall inner liner structure, it lowers the center of gravity of the product when the water is contained in the inner liner, thus preventing the product from shaking when the water boils and tumbles in the inner liner, avoiding product tipping and other safety risks. Furthermore, the heat-conducting element is located on the outer surface of the bottom of the inner liner. The heating assembly includes a first heating element and a second heating element. The arrangement of the first and second heating elements allows the heating assembly to evenly heat the bottom of the inner liner, ensuring uniform heat conduction and uniform temperature rise of the liquid inside the inner liner. This changes the tumbling direction of the boiling water, preventing water from splashing from the spout when the water boils due to uneven heating, further improving user safety and reducing noise when the liquid heating container is boiling water.

[0035] Existing liquid heating containers, typically used for heating liquids, such as electric kettles, generally suffer from problems like loud boiling noise, spots forming on the bottom after prolonged use, and difficulty in cleaning. Furthermore, some kettles with large, curved bottoms exhibit poor stability during boiling, as the center of gravity is higher, leading to noticeable shaking and potential tipping or safety hazards. The large, curved bottom also reduces the kettle's water capacity. This invention proposes a liquid heating container to address at least one of these problems. The liquid heating container can be an electric kettle, a health pot, a soymilk maker, a blender, or other devices capable of heating liquids; the following description uses an electric kettle as an example.
[0036] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the liquid heating container includes an inner liner 1, a heat-conducting element 2, and a heating assembly 3; the inner liner 1 includes a peripheral wall 11, a bottom wall 12, and a connecting wall 13 connecting the peripheral wall 11 and the bottom wall 12, the bottom wall 12 extends radially along the inner liner 1, and the connecting wall 13 is arc-shaped; the heat-conducting element 2 is disposed on the outer surface of the bottom of the inner liner 1; the heating assembly 3 includes a first heating element 31 and a second heating element 32, both of which are disposed on the surface of the heat-conducting element 2 away from the inner liner 1, and are spaced apart in the axial direction of the inner liner 1.
[0037] Specifically, the inner liner 1 has a water storage cavity for storing water or other heatable liquids. The inner liner 1 can be made of a heatable metal material, such as stainless steel, or it can be configured as a combination of part metal and part glass, with the metal and glass materials surrounding the water storage cavity. Heating the metal material heats the liquid inside the water storage cavity.
[0038] Please see Figure 4 and Figure 5 More specifically, the peripheral wall 11, bottom wall 12, and connecting wall 13 of the inner liner 1 are connected and enclosed to form a water storage cavity for storing water. The peripheral wall 11, bottom wall 12, and connecting wall 13 are integrally formed for easy manufacturing. The peripheral wall 11 is cylindrical, and the peripheral wall 11, bottom wall 12, and connecting wall 13 are made of a heatable metal material, such as stainless steel. The liquid heating container may include an outer shell (not shown in the figure), and the metal inner liner 1 is integrally disposed within the outer shell. In other embodiments, the edge of the peripheral wall 11 away from the bottom wall 12 may also be connected to a glass body. In this case, the liquid heating container does not have an outer shell structure, and the glass body allows the user to intuitively see the water level in the liquid heating container and the state of the water in the inner liner 1 during boiling.
[0039] The bottom wall 12 extends radially along the inner liner 1, meaning the bottom wall 12 of the inner liner 1 is flat. The bottom wall 12 and the peripheral wall 11 are connected by a connecting wall 13. Compared to the traditional structure where the peripheral wall 11 and the bottom wall 12 of the inner liner 1 are directly connected, the connecting wall 13 makes it easier for users to clean the inner liner 1, and prevents the accumulation of impurities at the connection between the peripheral wall 11 and the bottom wall 12. The connecting wall 13 is arc-shaped. Compared to the traditional structure of the inner liner 1, the arc-shaped wall makes it easier for users to clean the inner liner 1, and prevents the accumulation of impurities at the connection between the peripheral wall 11 and the bottom wall 12. It should be noted that the arc-shaped connecting wall 13 can be composed of multiple arc segments, or it can be designed as a large rounded corner to achieve a smooth transition between the peripheral wall 11 and the bottom wall 12.
[0040] Please see Figures 2 to 4 The heating assembly 3 includes a first heating element 31 and a second heating element 32. Both the first heating element 31 and the second heating element 32 are tubular, roughly C-shaped, and are arranged around the outside of the bottom of the inner liner 1. The heating assembly 3 heats the bottom of the inner liner 1. Simultaneously, to ensure uniform heating of the bottom of the inner liner 1 by the heating assembly 3 and to ensure uniform temperature rise of the liquid inside the inner liner 1, a heat-conducting component is also provided between the inner liner 1 and the heating assembly 3 to uniformly conduct the heat generated by the heating assembly 3 to the bottom of the inner liner 1. The bottom of the inner liner 1 refers to the area near the bottom of the inner liner 1, including but not limited to the area of the bottom wall 12, the connecting wall 13, and part of the peripheral wall 11 of the inner liner 1.
[0041] It should be noted that there are many sources of noise during the use of an electric kettle, such as the water quality and level inside the inner tank 1, the material of the inner tank 1 itself, or vibrations from the heating element 3. Specifically, during the heating process of the inner tank 1, if the heat conduction structure at the bottom of the inner tank 1 is uneven, the water inside will also be heated unevenly. During normal heating, heat is transferred through convection; that is, the water at the bottom, being less dense, rises, while the surrounding cooler water sinks to replenish it. However, if the heat conduction is uneven, it will cause some areas of water to heat up rapidly and produce steam, while other areas remain relatively cold. This temperature difference disrupts the water convection. The process of steam forming bubbles in an uneven temperature environment also becomes irregular. Under normal circumstances, bubbles will be generated and rise relatively evenly from the bottom, but now there will be a situation where a large number of bubbles are generated rapidly in some areas, while very few bubbles are generated in other areas.
[0042] Furthermore, when a large number of bubbles are rapidly generated and burst in a localized area, a relatively loud "gurgling" sound is produced. Moreover, due to localized overheating, water vapor passing through a cooler water layer produces a sharper "hissing" sound. These sounds are louder and more frequent than during normal, uniform heating. For example, during normal heating, the gurgling sound might be relatively gentle and regular, while with uneven heat conduction, the gurgling sound can become very noisy, similar to the sound of water violently boiling in a pot.
[0043] Meanwhile, the uneven generation and bursting of air bubbles can cause the inner liner 1 to vibrate. This vibration frequency may be close to the natural frequency of the kettle itself, thus triggering resonance. Just like striking a bell, when the external vibration frequency matches the natural frequency of the bell, the sound will be louder. In this situation, the kettle will emit a louder humming sound or a continuous low-frequency vibration noise than usual, making it seem as if the kettle is "shaking" and making noise.
[0044] Furthermore, when a large number of bubbles generated locally rise to the surface and burst, they cause violent fluctuations in the water surface. These fluctuations cause the water to hit the inner wall of the kettle, producing a "slapping" sound. Under normal circumstances, the water slapping sound is relatively quiet, but under conditions of uneven heat conduction, the sound will become louder and more frequent due to the violent fluctuations in the water surface.
[0045] In this embodiment, the first heating element 31 and the second heating element 32 are both disposed on the surface of the heat-conducting element 2 away from the inner liner 1, and are arranged at intervals in the axial direction of the inner liner 1. By heating the bottom of the inner liner 1 with the first heating element 31 and the second heating element 32, the heating assembly 3 can evenly heat the bottom of the inner liner 1, thereby allowing the heat-conducting element 2 to conduct heat evenly. This ensures that the liquid in the inner liner 1 heats up evenly, thereby changing the turbulence direction when the water boils. This prevents water from splashing spouts when the water in the inner liner 1 boils due to uneven heating by the heating assembly 3, further improving user safety.
[0046] Meanwhile, the heating component 3 heats the bottom evenly, and the heat-conducting component 2 conducts heat evenly. This means that during the heating process, heat can be transferred to the water more evenly, reducing local overheating and the rapid formation and rupture of bubbles, thus reducing the overall noise of the liquid heating container during the water heating process.
[0047] The technical solution of this utility model, by configuring the inner liner 1 as including a peripheral wall 11, a bottom wall 12, and a connecting wall 13 connecting the peripheral wall 11 and the bottom wall 12, with the bottom wall 12 extending radially along the inner liner 1, facilitates cleaning of the inner liner 1. Furthermore, compared to the traditional inner liner 1 structure with a large arc-shaped bottom wall 12, it lowers the center of gravity of the inner liner 1 within the overall product structure, thus preventing the product from easily shaking when the water boils and tumbles in the inner liner 1, avoiding product tipping and other safety risks. Additionally, the heat-conducting component 2 is disposed on the outer surface of the bottom of the inner liner 1. The heating component 3 includes a first heating element 31 and a second heating element 32. By setting the first heating element 31 and the second heating element 32, the heating component 3 can evenly heat the bottom of the inner pot 1, thereby allowing the heat conduction element 2 to conduct heat evenly. This ensures that the liquid in the inner pot 1 heats up evenly, thereby changing the rolling direction of the water when it boils. This prevents water from splashing spouts when the water in the inner pot 1 boils due to uneven heating by the heating component 3, further improving the safety of the user and also reducing the noise of the liquid heating container when boiling water.
[0048] Please see Figures 6 to 9In one embodiment, the heat-conducting component 2 includes a first heat-conducting part 21 and a second heat-conducting part 22 connected to each other. The first heat-conducting part 21 is located inside the second heat-conducting part 22. The first heat-conducting part 21 is used to fit against the bottom wall 12, and the second heat-conducting part 22 is used to fit against the connecting wall 13. Specifically, the first heat-conducting part 21 is arranged in a circular plate shape and is used to fit against the surface of the heat-conducting component 2. The shape of the second heat-conducting part 22 is adapted to the shape of the connecting wall 13. When the heating assembly 3 heats, the heat transferred to the heat-conducting component 2 can be transferred to the connecting wall 13 of the inner liner 1 through the second heat-conducting part 22, so as to heat the connecting wall 13 of the inner liner 1 as well, thereby increasing the heat transfer area of the heat-conducting assembly to the entire inner liner 1 and improving the heating efficiency.
[0049] Please see Figure 4 and Figure 5 Furthermore, the first heating element 31 and the second heating element 32 are disposed on the outer surface of the second heat-conducting part 22, with the first heating element 31 located inside the second heating element 32. Disposing the heating assembly 3 on the outer surface of the second heat-conducting part 22 facilitates the welding and installation of the heating assembly 3 and the heat-conducting element 2. Simultaneously, it provides sufficient installation space on the outer surface of the first heat-conducting part 21 for installing the temperature controller 4 component of the liquid heating container. Further, the lower surface of the first heat-conducting part 21 is provided with a plurality of first positioning ribs 25, a plurality of second positioning ribs 26, and a plurality of connecting posts 27. The plurality of first positioning ribs 25 and the plurality of second positioning ribs 26 are used for positioning the first heating element 31 and the second heating element 32 during installation and welding, and the plurality of connecting posts 27 are used for positioning the temperature controller 4 during installation. Of course, in other embodiments, one of the first heating element 31 and the second heating element 32 may also be disposed on the outer surface of the first heat-conducting part 21; this is not specifically limited.
[0050] Please see Figure 3In one embodiment, the first heating element 31 has a first opening 31a spaced apart at both ends, and the second heating element 32 has a second opening 32a spaced apart at both ends, with the first opening 31a and the second opening 32a facing opposite directions. Specifically, since the first heating element 31 and the second heating element 32 are arranged in a C-shaped tubular configuration, when the first heating element 31 and the second heating element 32 are heating, the positions of the first opening 31a and the second opening 32a have no heat source and are relatively low in heat compared to other parts. During the heating process, water near the first heating element 31 and the second heating element 32 will be heated first, while water further away from the first heating element 31 and the second heating element 32 will take longer to reach the same temperature. This results in an uneven water temperature distribution within the inner tank 1. This uneven heating not only affects the user experience but may also lead to overheating of some water, resulting in a large number of bubbles being generated rapidly in some areas while very few bubbles are generated in other areas, as mentioned above, which will further lead to louder noise when boiling water. Therefore, by setting the orientations of the first opening 31a and the second opening 32a to opposite directions, the first heating element 31 and the second heating element 32 can evenly heat the bottom of the inner liner 1, thereby avoiding the aforementioned problems. Preferably, the orientations of the first opening 31a and the second opening 32a are opposite. That is, when the orientations of the first opening 31a and the second opening 32a are the same, it is considered that the angle between them is 0 degrees. Therefore, setting the orientations of the first opening 31a and the second opening 32a to opposite directions means that the angle between the first opening 31a and the second opening 32a is 180 degrees.
[0051] Please see Figure 4 In one embodiment, the diameter of the bottom wall 12 is D1, and the diameter of the peripheral wall 11 is D2, satisfying 1 > D1 / D2 > 0.5. Specifically, the bottom wall 12 is circular, with a diameter of D1 and a diameter of D2, satisfying 1 > D1 / D2 > 0.5. That is, the diameter of the bottom wall 12 is at least larger than the radius of the peripheral wall 11. This arrangement facilitates cleaning of the inner tank 1 and lowers the center of gravity of the product when the water in the inner tank 1 is filled. This makes the product less prone to shaking when the water boils and tumbles in the inner tank 1, preventing product tipping and other safety risks.
[0052] Furthermore, D1 and D2 satisfy 0.65 > D1 / D2 > 0.5. Specifically, the ratio of D1 to D2 is preferably in the range of 0.5-0.65. This facilitates cleaning of the inner tank 1 and lowers the center of gravity of the product when the water in the inner tank 1 is filled. As a result, when the water boils and tumbles in the inner tank 1, the product is less likely to shake, thus avoiding product tipping and other safety risks.
[0053] Please see Figure 5In one embodiment, in the axial direction of the inner liner 1, the height of the connecting wall 13 is H1, and the height of the heat-conducting component 2 is H2, satisfying H1 > H2 > H1 / 2. This arrangement allows the heat-conducting component 2 to cover the connecting wall 13 as much as possible, enabling heat conduction and heating of the connecting wall 13, thereby improving heating efficiency. Furthermore, since the shape of the second heat-conducting portion 22 of the heat-conducting component 2 matches the shape of the connecting wall 13, it also facilitates the manufacturing of the heat-conducting component 2 and the welding of the heat-conducting component 2 to the connecting wall 13.
[0054] Please see Figure 5 In one embodiment, the shortest distance between the heating component 3 and the end of the heat-conducting element 2 in the axial direction of the inner liner 1 is L1, which satisfies L1 ≥ 8 mm. Specifically, configuring the distance between the heating component 3 and the end of the heat-conducting element 2 to be greater than 8 mm can ensure the uniformity of heat transfer between the first heating element 31 and the second heating element 32, while also improving the noise level when the liquid heating container is boiling water. Exemplary values for L1 can be 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm.
[0055] Please see Figure 5 In one embodiment, the distance between the first heating element 31 and the second heating element 32 in the axial direction of the inner liner 1 is L2, satisfying 30mm ≥ L2 ≥ 5mm. Specifically, the shortest distance between the first heating element 31 and the second heating element 32, which are arranged in a C-shape, in the axial direction of the inner liner 1 is L2, satisfying 30mm ≥ L2 ≥ 5mm. This arrangement further ensures the uniformity of heating the bottom of the inner liner 1 by the first heating element 31 and the second heating element 32, thereby ensuring that the water in the inner liner 1 can be heated evenly and reducing noise. Examples of values for L2 include 5mm, 7mm, 9mm, 10mm, 13mm, 15mm, 18mm, 20mm, 25mm, and 30mm.
[0056] Please see Figure 4 and Figure 5 In one embodiment, the diameter of the bottom wall 12 is D1, and the height of the connecting wall 13 is H1, satisfying D1≥H1. Specifically, the height of the connecting wall 13 refers to the height of the connecting wall 13 in the axial direction of the inner liner 1. Setting the diameter of the bottom wall 12 to be no less than the height of the connecting wall 13 can lower the center of gravity of the inner liner 1 in the overall product, thereby making the product less prone to shaking when the water boils and tumbles in the inner liner 1, avoiding product tipping and other safety risks.
[0057] Please see Figures 6 to 9In one embodiment, the second heat-conducting part 22 is provided with a plurality of strip-shaped notches 22a, which are arranged at intervals along the circumference of the second heat-conducting part 22. Specifically, the bottom of the heat-conducting component 2 and the inner liner 1 are connected by welding. The plurality of strip-shaped notches 22a on the second heat-conducting part 22 serves two purposes: firstly, it allows the solder between the bottom of the second heat-conducting part 22 and the inner liner 1 to flow out, thus removing welding slag; secondly, it ensures the stability of the welding between the second heat-conducting part 22 and the inner liner 1. The number of strip-shaped notches 22a is set to 4-8. Further, the width of the strip-shaped notches 22a is between 0.5mm and 4mm. The width of the strip-shaped notches 22a can be exemplarily 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm.
[0058] Please see Figure 6 and Figure 7 In one embodiment, the side of the heat-conducting component 2 that is in contact with the inner liner 1 is provided with a plurality of first grooves 23 arranged at intervals along the circumference of the heat-conducting component 2. The first grooves 23 are formed in the first heat-conducting part 21 and the second heat-conducting part 22; and / or, the first heat-conducting part 21 is provided with a plurality of second grooves 24 arranged at intervals along its circumference. Specifically, the heat-conducting component 2 may be provided with a plurality of first grooves 23, which are formed in the first heat-conducting part 21 and the second heat-conducting part 22 and are arranged at intervals along the circumference of the heat-conducting component 2. The plurality of first grooves 23 can play a role in venting and removing welding slag during the welding process between the heat-conducting component 2 and the inner liner 1, and at the same time, can ensure that the surfaces in contact between the heat-conducting component 2 and the inner liner 1 are completely welded together by the solder, thus ensuring the stability of the welding between the heat-conducting component 2 and the inner liner 1. Alternatively, multiple second grooves 24 can be formed on the first heat-conducting part 21. Similarly, the multiple second grooves 24 play a role in venting and removing welding slag during the welding process between the heat-conducting component 2 and the inner liner 1. At the same time, they can also ensure that the contact surfaces of the heat-conducting component 2 and the inner liner 1 are completely welded together by the solder, thus ensuring the stability of the welding between the heat-conducting component 2 and the inner liner 1. Alternatively, multiple first grooves 23 and multiple second grooves 24 can be provided on the heat-conducting component 2 at the same time. The number of first grooves 23 can be set to 4-8, and the number of second grooves 24 can be set to 4-8.
