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 an electric kettle as an example, a heating element is usually installed on the outer bottom of the inner liner to heat the inner liner. However, this heating method has low heating efficiency and poor heating uniformity. Utility Model Content

[0003] The main purpose of this invention is to provide a liquid heating container that aims to improve the heating efficiency of the heating tube on the inner liner.

[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 tube. 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 tube is spirally wound around the surface of the heat-conducting component away from the inner liner, wherein the surface of the heat-conducting component that is in contact with the heating tube is a convex arc surface, and the surface of the heating tube that is in contact with the heat-conducting component is a concave arc surface.

[0005] In one embodiment, the length of the heating tube is greater than 1.5 times the circumference of the end of the heat-conducting element away from the liner opening.

[0006] In one embodiment, the heat-conducting component includes a first heat-conducting part and a second heat-conducting part connected to each other. The first heat-conducting part is located inside the second heat-conducting part. The first heat-conducting part is used to fit against the bottom wall, and the second heat-conducting part is used to fit against the connecting wall.

[0007] In one embodiment, the heating tube is wound around the outer surface of the second heat-conducting part.

[0008] 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.

[0009] In one embodiment, in the axial direction of the inner liner, the distance between the heating tube and the end of the heat-conducting element is L1, which satisfies L1≥8mm.

[0010] In one embodiment, the distance between two spirally wound heating tubes in the axial direction of the inner liner is L2, which satisfies 30mm≥L2≥5mm.

[0011] In one embodiment, the height of the connecting wall is H1, satisfying D1≥H1.

[0012] 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.

[0013] In one embodiment, the connecting wall is arranged in an arc shape.

[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 side of the first heat-conducting portion that is in contact with the inner liner is provided with a plurality of second grooves arranged at intervals along its circumference.

[0016] The technical solution of this utility model involves configuring the inner liner as a structure including 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. A heat-conducting element is disposed on the outer surface of the bottom of the inner liner, and a heating tube is spirally wound around the surface of the heat-conducting element away from the inner liner. The surface of the heat-conducting element that contacts the heating tube is a convex arc surface, while the surface of the heating tube that contacts the heat-conducting element is a concave arc surface. Thus, the convex and concave arc surfaces increase the contact area between the heating tube and the heat-conducting element, thereby increasing the heating area. Simultaneously, the heating tube can evenly heat the bottom, allowing the heat-conducting element to conduct heat evenly, ensuring uniform heating of the liquid inside the inner liner and improving the heating efficiency of the heating tube. On the other hand, the arc-shaped connecting wall facilitates cleaning of the inner liner. Compared to the traditional large arc-shaped bottom wall structure of the inner liner, it lowers the center of gravity of the product when the water is in the inner liner. This makes the product less prone to shaking when the water boils and tumbles in the inner liner, avoiding product tipping and other safety risks. Furthermore, it allows the heating element to heat the bottom evenly, ensuring that the heat conduction components can conduct heat evenly and guaranteeing that the liquid in the inner liner heats up uniformly. This changes the direction of water tumbling when boiling, preventing water from splashing from the spout when the water boils due to uneven heating of the heating element, further improving user safety and reducing noise when the liquid heating container is boiling water.

[0035] Existing liquid heating containers are typically used to heat liquids, with electric kettles serving as an example. In electric kettles, a heating element is usually installed on the outer bottom of the inner liner to heat it. However, this heating method has low efficiency and poor heating uniformity. This invention proposes a liquid heating container that improves the heating efficiency of the heating element on the inner liner. The liquid heating container can be an electric kettle, a health pot, a soymilk maker, a blender, or other devices that can heat liquids; the following description uses an electric kettle as an example.

[0036] Please see Figures 1 to 4In one embodiment of this utility model, the liquid heating container includes an inner liner 1, a heat-conducting element 2, and a heating tube 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 tube 3 is spirally wound around the surface of the heat-conducting element 2 away from the inner liner 1, wherein the surface of the heat-conducting element 2 that is in contact with the heating tube 3 is a convex arc surface, and the surface of the heating tube 3 that is in contact with the heat-conducting element 2 is a concave arc surface.

[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 2 and Figure 3 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 that 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 with the traditional structure where the peripheral wall 11 and the bottom wall 12 of the inner liner 1 are directly connected, the setting of the connecting wall 13 makes it easier for users to clean the inner liner 1, and there will be no accumulation of impurities at the connection between the peripheral wall 11 and the bottom wall 12.

[0040] The connecting wall 13 is arc-shaped. Specifically, the peripheral wall 11 and bottom wall 12 of the inner liner 1 are connected by an arc-shaped wall. Compared with the traditional inner liner 1 structure, the arc-shaped wall makes it easier for users to clean the inner liner 1, and there is no 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.

[0041] The bottom wall 12 is circular, with a diameter of D1 and a diameter of D2 for the peripheral wall 11, satisfying 1 > D1 / D2 > 0.5. In other words, the diameter of the bottom wall 12 is at least larger than the radius of the peripheral wall 11. This design facilitates cleaning of the inner tank 1 and lowers the center of gravity of the product when filled with water. This prevents the product from easily shaking when the water boils and tumbles in the inner tank 1, thus avoiding product tipping and other safety risks.

[0042] Please see Figure 3 The heating tube 3 is spirally wound around the outside of the bottom of the inner liner 1, allowing for uniform heating of the bottom area of ​​the inner liner 1. To ensure uniform heating of the bottom of the inner liner 1 and consistent temperature rise of the liquid within the inner liner 1, a heat-conducting element 2 is installed between the inner liner 1 and the heating tube 3 to evenly transfer the heat generated by the heating tube 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 bottom wall 12, connecting wall 13, and part of the peripheral wall 11.

[0043] 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, water transfers heat 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 will disrupt 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In this embodiment, the heating tube 3 is spirally wound around the surface of the heat-conducting element 2 away from the inner liner 1. The surface of the heat-conducting element 2 that contacts the heating tube 3 is a convex arc surface, and the surface of the heating tube 3 that contacts the heat-conducting element 2 is a concave arc surface. The convex and concave arc surfaces increase the contact area between the heating tube 3 and the heat-conducting element 2, thereby increasing the heating area. Simultaneously, the heating tube 3 can heat the bottom evenly, allowing the heat-conducting element 2 to conduct heat evenly, ensuring uniform heating of the liquid inside the inner liner 1 and improving the heating efficiency of the heating tube 3. Furthermore, this arrangement can change the direction of water turbulence during boiling, preventing water from splashing from the spout when the water boils due to uneven heating by the heating tube 3, further enhancing user safety.

[0048] Meanwhile, the heating tube 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, improving heating efficiency, reducing local overheating and rapid formation and rupture of bubbles, and reducing the overall noise of the liquid heating container during the water heating process.

[0049] The technical solution of this utility model is to set 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. The bottom wall 12 extends radially along the inner liner 1, the connecting wall 13 is arc-shaped, and the heat-conducting element 2 is set on the outer surface of the bottom of the inner liner 1. The heating tube 3 is spirally wrapped around the surface of the heat-conducting element 2 away from the inner liner 1. The surface of the heat-conducting element 2 and the heating tube 3 that are in contact is a convex arc surface, and the surface of the heating tube 3 and the heat-conducting element 2 that are in contact is a concave arc surface. In this way, on the one hand, it facilitates the cleaning of the inner liner 1, and on the other hand, compared with the traditional large arc-shaped bottom wall 12 inner liner 1 structure, it lowers the center of gravity of the inner liner 1 when filled with water in the product. This makes the product less likely to shake when the water boils and tumbles in the inner liner 1, avoiding product tipping and other safety risks. On the other hand, it allows the heating element 3 to heat the bottom evenly, improving heating efficiency, and also allows the heat conduction element 2 to conduct heat evenly, ensuring that the liquid in the inner liner 1 heats up evenly. This changes the tumbling direction of the water when boiling, avoiding the situation where water splashes spout from the spout when the water in the inner liner 1 boils due to uneven heating by the heating element 3, further improving user safety, and also further reducing the noise of the liquid heating container when boiling water.

[0050] In one embodiment, the length of the heating tube 3 is greater than 1.5 times the circumference of the end of the heat-conducting element 2 furthest from the opening of the inner liner 1. This arrangement ensures that the heating tube 3 has sufficient length, allowing for more turns around the outer surface of the heat-conducting element 2, increasing the contact area between the heating tube 3 and the heat-conducting element 2, thereby increasing the heating area. This allows the heating tube 3 to heat the bottom evenly, and the heat-conducting element 2 to conduct heat evenly, ensuring uniform heating of the liquid inside the inner liner 1 and improving the heating efficiency of the heating tube 3 on the inner liner 1.

[0051] Please see Figures 6 to 9 In 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 tube 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 to heat the connecting wall 13 of the inner liner 1 as well, thereby increasing the heat transfer area of ​​the heat-conducting component to the entire inner liner 1 and improving the heating efficiency.

[0052] Please see Figure 2 and Figure 4Furthermore, the heating tube 3 is wound around the outer surface of the second heat-conducting part 22. Specifically, placing the heating tube 3 on the outer surface of the second heat-conducting part 22 facilitates the welding and installation of the heating tube 3 and the heat-conducting component 2. At the same time, 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. Even 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 heating tube 3 during installation and welding, and the plurality of connecting posts 27 are used for positioning the temperature controller 4 during installation.

[0053] Please see Figure 5 In 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 distance between the heating tube 3 and the end of the heat-conducting element 2 in the axial direction of the inner liner 1 is L1, which satisfies L1≥8mm. Specifically, configuring the distance between the heating tube 3 and the end of the heat-conducting element 2 to be greater than 8mm can ensure the uniformity of heat transfer from the heating tube and improve the noise when the liquid heating container is boiling water. Exemplary values ​​for L1 can be 8mm, 9mm, 10mm, 11mm, and 12mm.

[0055] Please see Figure 5 In one embodiment, the distance between two spirally wound heating tubes 3 in the axial direction of the inner liner 1 is L2, which satisfies 30mm ≥ L2 ≥ 5mm. Specifically, the spirally wound heating tubes 3 can be wound in the circumferential direction of the inner liner 1, or they can be wound from the bottom wall 12 of the inner liner 1 to the liner opening. That is, any one spiral of the heating tube 3 forms a plane, which can be perpendicular to the axial direction of the inner liner 1 or have a certain angle with the axial direction of the inner liner 1. Examples of values ​​for L2 are 5mm, 7mm, 9mm, 10mm, 13mm, 15mm, 18mm, 20mm, 25mm, and 30mm.

[0056] Please see Figure 4 and Figure 5In one embodiment, 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 greater 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 Figure 4 In one embodiment, 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.

[0058] Please see Figures 6 to 9 In 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.

[0059] Please see Figure 6 and Figure 7In 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 side of the first heat-conducting part 21 that is in contact with the inner liner 1 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.
