Description

Technical Field

[0001] This invention relates to the field of heating device technology, and in particular to a conductive heating device adapted to various pot bottom shapes. Background Technology

[0002] In daily cooking, the bottom of cooking containers is prone to deformation due to prolonged high-temperature heating, bumps, and other factors during handling, resulting in an uneven bottom that affects heating efficiency. Most mainstream conductive heating devices on the market currently have a fixed, one-piece heating plate structure, which cannot be adjusted to fit the deformed shape of the pot bottom.

[0003] The fixed heating plate of this type does not make sufficient contact with the deformed pot bottom, achieving only localized heat transfer. This not only leads to uneven heating of the pot bottom, affecting cooking quality, but also causes significant heat loss and reduces heating efficiency. Furthermore, the fixed heating plate cannot adapt to pot bottoms with varying degrees of deformation, easily resulting in poor heat transfer and localized overheating, making it difficult to meet practical usage needs.

[0004] In view of the technical shortcomings of existing integrated heating plates, such as inability to adapt to deformed pot bottoms, large heat loss, and poor heating effect, there is an urgent need for a conductive heating device that can adapt to deformed pot bottoms. This invention is proposed to solve the above-mentioned technical pain points. Summary of the Invention

[0005] The purpose of this invention is to provide a conductive heating device that is adaptable to various pot bottom shapes, solving the problems of existing integrated heating plates being unable to adapt to deformed pot bottoms, having high heat loss, and poor heating effect.

[0006] To achieve the above objectives, the present invention provides a conductive heating device adaptable to various pot bottom shapes, including a support base, a heat generation component, a heating support plate, and an elastic conductive component; The support base and the heating support plate are fixedly or detachably connected by a support structure, forming an installation space for accommodating the heat energy generating component. The size of the installation space is adapted to the external size of the heat energy generating component. The heat generation component is assembled in the installation space. Specifically, the heat generation component is located below the heating support plate and maintains a preset distance from the heating support plate. The heat generation component provides a heat source for the heated support plate and / or the elastic conduction component. The elastic conductive component enables heat transfer. At least one is arranged on the heating support plate and is movably installed through the heating support plate. One end of the component extends out of the heating support plate on the side away from the installation space. The end face of the extended end is used to contact the bottom of the container to be heated. The elastic conductive component can reciprocate and extend along the vertical direction of the heating support plate. The extension and retraction stroke of the elastic conductive component can adapt to the shape and undulation of the bottom of the container to be heated, so as to achieve contact with the bottom of the container to be heated and conduct heat through elastic extension and retraction.

[0007] Preferably, the heating support plate is provided with a guide through structure for the elastic heat conductor to move through, and the elastic heat conductor is slidably engaged with the guide through structure.

[0008] Preferably, the heating support plate is thermally connected to the heat generation component, and the heat energy is transferred from the heat generation component to the heating support plate, then from the heating support plate to the elastic heat conductor, and then to the container to be heated.

[0009] Preferably, the elastic thermal conductive element includes a thermal conductive element and an elastic element; the thermal conductive element can movably penetrate the heating support plate, with one end for contacting the bottom of the container to be heated, and the other end extending into the support base and abutting against the elastic element; the elastic element is disposed in the support base to provide elastic expansion and contraction force for the thermal conductive element, so as to realize the reciprocating expansion and contraction of the thermal conductive element.

[0010] Preferably, one end of the heat-conducting component extending into the support base is provided with a limiting structure, and the support base is provided with a stepped limiting hole. One end of the heat-conducting component extending into the support base passes through the stepped limiting hole. One side of the limiting structure abuts against the elastic component, and the elastic force of the elastic component drives the other side of the limiting structure to press against the stepped limiting hole.

[0011] Preferably, the limiting structure is a flange, which is adapted to the stepped surface of the stepped limiting hole.

[0012] Preferably, a plurality of the elastic thermal conductive elements are uniformly arranged around the circumference of the heating support plate to form a first heating ring.

[0013] Preferably, a plurality of the elastic thermal conductive elements are arranged around the heating support plate to form a second heating ring, which is located around the first heating ring.

[0014] Preferably, the heat generation component is disposed in the area between the first heating coil and the second heating coil. The beneficial effects of this invention are: 1. Adaptive Fit, Solving the Problem of Uneven Heating in Deformed Pot Bottoms: This invention utilizes multiple independent, elastically expandable heat-conducting components. Each component can reciprocate vertically and, under the continuous thrust of an elastic element (such as a compression spring), maintains a tight fit to the concave-convex shape of the pot bottom. Regardless of whether the pot bottom is concave, convex, or wavy, all heat-conducting components can achieve zero-gap contact with all parts of the pot bottom. This completely eliminates the air thermal resistance caused by pot bottom deformation in traditional integrated heating plates, significantly improving heat conduction efficiency and avoiding localized overheating or cold spots, achieving truly uniform, fully fitted heating.

[0015] 2. Dual-ring heating layout, covering various cookware sizes: This invention uses an elastic heat conductor to evenly form a first heating ring and a second heating ring along the circumference, with the inner and outer rings corresponding to different diameters of pot bottoms. Small-sized pots are independently heated by the inner ring, while large-sized pots are supported by both the inner and outer rings, adapting to various pot types from household milk pots to large-diameter steamers without the need to replace the heating plate. Simultaneously, the independent extension and retraction of the dual rings can accommodate localized deformation of the pot bottom (such as only a central bulge or only edge warping), significantly improving the versatility and adaptability of the device.

[0025] The components include: a bearing base 1; a stepped limiting hole 11; a heat generation component 2; a heating bearing plate 3; a guide through structure 31; an elastic conduction component 4; a heat conduction component 41; a limiting structure 411; an elastic component 42; a first heating ring 5; and a second heating ring 6. Detailed Implementation

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0027] like Figure 1 , Figure 2 As shown, the present invention provides a conductive heating device adapted to various pot bottom shapes, including a support base 1, a heat generation component 2, a heating support plate 3, and an elastic conductive component 4.

[0028] The support base 1 supports the overall structure, and its top is equipped with a support column, which serves as a support structure for the heating support plate 3. The heating support plate 3 is made of a thermally conductive metal, such as aluminum alloy or copper, which have high thermal conductivity, and is fixed or detachably connected to the support column by screws or other means. An installation space is formed between the heating support plate 3 and the support base 1, allowing the heat generation component 2 to be fixed. The inner diameter and height of this installation space are adapted to the external dimensions of the heat generation component 2. This design stably constrains the heat generation component 2 in a predetermined position, preventing heat source displacement or component collision due to shaking during use. Simultaneously, the enclosed installation space reduces ineffective heat loss to the surroundings, concentrating most of the heat energy upwards for transfer, thereby significantly improving thermal efficiency.

[0029] In one embodiment, the heating support plate 3 is a circular metal plate, but other shapes are also possible, such as rectangular, elliptical, polygonal, or irregular shapes. It should stably support the container to be heated, accommodate the arrangement of the elastic conductive components 4, and form an installation space with the support base 1. A rectangular heating support plate 3 can be adapted to a rectangular pot bottom, and an elliptical plate can be adapted to an elliptical pot bottom, thus breaking through the traditional limitations of circular heating plates and enabling the device to match various irregularly shaped pots or specific cooking utensils, further expanding its applicability and meeting the diverse needs of different users.

[0030] The heat generation component 2 can be a ring-shaped heating tube, the power of which can be set according to actual cooking needs, and is installed in the installation space between the support base 1 and the heating support plate 3. Specifically, in this embodiment, the heat generation component 2 is located below the heating support plate 3 to provide a heat source for the heating support plate 3 and / or the elastic conduction component 4.

[0031] In one embodiment, such as Figure 3As shown, a certain preset distance (e.g., 1-5mm) is maintained between the heat generation component 2 and the heating support plate 3. This distance ensures efficient heat radiation transfer while preventing local overheating damage to the heating support plate 3, ensuring that heat energy can be quickly transferred to the heating support plate 3 and the subsequent elastic conductive component 4. If the distance is too small, the local temperature rise of the heating support plate 3 will be too rapid, which may easily lead to metal fatigue or deformation, or even burn out the heat conduction component 41; if the distance is too large, the heat radiation efficiency will decrease and energy consumption will increase. The preset distance can achieve the optimal balance between thermal efficiency and safety, while reserving a small space for the thermal expansion of the heating support plate 3 to prevent thermal stress damage.

[0032] In one embodiment, such as Figure 4 As shown, a certain preset distance is maintained between the heat generation component 2 and the heating support plate 3. This preset distance can also be zero, meaning the heating surface of the annular electric heating tube is directly attached to the bottom surface of the heating support plate 3. This direct attachment method minimizes heat loss in the air and improves thermal response speed, making it particularly suitable for cooking scenarios requiring rapid heating or high power density. To ensure uniform adhesion and avoid localized overheating, thermally conductive grease can be applied between the contact surfaces, or thermally conductive pads can be used to compensate for manufacturing tolerances and improve thermal contact.

[0033] It should be noted that, regardless of whether gap bonding or direct bonding is used, as long as effective heat transfer can be achieved between the heat generation component 2 and the heating support plate 3, and the requirements for temperature uniformity and structural stability of the device under different operating conditions are met, it falls within the protection scope of this invention.

[0034] Furthermore, multiple elastic conductive components 4 are provided, which can be made of materials with high thermal conductivity such as copper. For details, please refer to [link / reference]. Figure 2The elastic conductive component 4 includes a heat-conducting element 41 and an elastic element 42, wherein the elastic element 42 is a compression spring, forming a structure that can elastically extend and retract. The heating support plate 3 is provided with corresponding circular guide through-structures 31, through which the heat-conducting element 41 can movably pass, achieving a sliding fit with the guide through-structure 31. This allows the heat-conducting element 41 to flexibly extend and retract in a direction perpendicular to the heating support plate 3, adapting to different pot bottom shapes. The upper end of the heat-conducting element 41 protrudes from the side of the heating support plate 3 away from the installation space. The end face of this protruding end is polished smooth and flat for contact with the bottom of the container to be heated. The lower end of the heat-conducting element 41 extends into the support base 1 and abuts against the elastic element 42. The elastic element 42 is vertically installed inside the support base 1, with its lower end fixedly connected to the bottom of the support base 1 and its upper end abutting against the heat-conducting element 41, providing a continuous elastic force to the heat-conducting element 41. This drives the heat-conducting element 41 to reciprocate and extend, ensuring that the upper end of the heat-conducting element 41 can tightly fit the bottom of the pot, and the extension stroke can adapt to the undulation of the pot bottom. When a traditional integrated heating plate encounters a deformed pot bottom, only the raised local area can contact the heat transfer, while air gaps are formed in the recessed areas, resulting in severely uneven heating and a large amount of heat waste. In this solution, each elastic conductive component 4 extends and retracts independently. Regardless of whether the pot bottom is concave, convex, or wavy, each heat-conducting element 41 can always fit tightly against the pot bottom under the action of elastic force, thereby directly transferring heat to all parts of the pot bottom, completely eliminating the thermal resistance and local overheating risk caused by gaps, and achieving true full-fit uniform heating.

[0035] In one embodiment, a compression spring is not the only alternative to the elastic element 42. Elastic rubber columns, disc springs, wave springs, or elastic silicone components can also be used as substitutes. Any component that can provide a continuous and stable elastic force to the heat-conducting element 41, driving it to reciprocate and expand, and possesses high-temperature resistance and resistance to aging, can be used in this device. Elastic rubber columns are simple in structure and low in cost, while disc springs have strong load-bearing capacity and can be flexibly selected according to the overall size and force requirements of the device. Different elastic elements 42 have their own advantages in stiffness, stroke, temperature resistance, and cost. Providing multiple alternatives allows this device to be optimized for different application scenarios (such as household, commercial, and industrial use), thereby enhancing its industrial adaptability and scalability.

[0036] To prevent the heat-conducting component 41 from detaching from above during use, the support base 1 is provided with stepped limiting holes 11 corresponding to the installation position of each heat-conducting component 41 (e.g., Figure 5As shown, the stepped limiting hole 11 has a stepped structure with a smaller upper end and a larger lower end. The end of the heat-conducting component 41 that extends into the bearing base 1 has an integrally formed annular flange as a limiting structure 411. The outer diameter of this limiting structure 411 is larger than the inner diameter of the guide through structure 31 on the heating bearing plate 3, and also larger than the diameter of the upper end of the stepped limiting hole 11. After assembly, the upper surface of the limiting structure 411 faces the stepped surface of the stepped limiting hole 11. The elastic element 42 (compression spring) is sleeved on the lower end of the heat-conducting component 41 or abuts against the lower surface of the limiting structure 411. The elastic force of the elastic element 42 pushes the heat-conducting component 41 upwards, causing the upper surface of the limiting structure 411 to press tightly against the stepped surface, thereby effectively preventing the heat-conducting component 41 from detaching upwards and ensuring structural stability. The limiting structure 411 converts the elastic force of the elastic element 42 into a limiting force: under normal working conditions, the elastic force is used to both adhere to the bottom of the pot and simultaneously press the limiting structure 411 firmly onto the stepped surface to prevent it from coming off; when the bottom of the pot is removed, the heat-conducting element 41 will not pop out of the device due to the elastic force, thus ensuring safety and ease of disassembly and assembly. In contrast, if only the friction between the heat-conducting element 41 and the guide hole or a simple retaining ring is used for limiting, it is easy to loosen or fall off after long-term use, while the stepped surface of this solution has a self-locking characteristic when it cooperates with the limiting structure 411, resulting in higher reliability.

[0037] Regarding the extension form of the limiting structure 411, it can either extend outward along the end face of the lower end of the heat-conducting element 41 to form an end face protrusion, which is easy to process, has a large contact area, and a reliable limiting effect; or it can protrude outward along the side wall of the lower end of the heat-conducting element 41 to form an annular flange. As long as it can effectively abut against the stepped surface, it falls within the protection scope of this invention.

[0038] In one embodiment, such as Figure 6As shown, the support base 1 includes an upper shell and a lower shell, which are detachably connected by means of snaps, screws, or threads. When engaged, they together form an internal space for housing the heat generation component 2 and the elastic conduction component 4. Multiple connecting posts are integrally formed or fixedly installed within the upper shell. Each connecting post extends vertically and has a stepped limiting hole 11 inside, which cooperates with the limiting structure 411 at the lower end of the heat-conducting component 41. The heat-conducting component 41 passes sequentially from top to bottom through the guide through structure 31 on the heating support plate 3 and the stepped limiting hole 11 in the connecting post. The limiting structure 411 at its lower end is located within the large hole section of the connecting post and abuts against the stepped surface. An elastic element 42 (such as a compression spring) is sleeved on the lower end of the heat-conducting component 41, with its upper end abutting against the lower surface of the limiting structure 411 and its lower end abutting against the inner wall of the lower shell. The detachable connection between the upper and lower shells facilitates the replacement or repair of the elastic element 42 and the heat-conducting element 41 without damaging the entire bearing base 1. In addition, the connecting column integrates the stepped limiting hole 11 with the shell body, which not only ensures the reliability of the limiting function but also reduces the number of independent parts, thus improving assembly efficiency.

[0039] It should be noted that both the upper and lower shells in this embodiment are injection molded from high-temperature resistant plastic, and the bottom of the lower shell is also provided with ventilation holes or heat dissipation structures to assist the heat generation component 2 in dissipating heat and prevent excessive internal temperature from affecting the life of the elastic element 42. This split-type load-bearing base 1 structure can be implemented as an independent solution or in parallel with the aforementioned integrated load-bearing base 1 solution, allowing users to choose according to actual production conditions.

[0040] like Figure 7 As shown, to fully cover pot bottoms of different sizes, multiple elastic conductive components 4 are evenly arranged around the circumference of the heating support plate 3 to form a first heating ring 5. For example, the diameter of the first heating ring 5 can be set to 15~20cm, and the distance between two adjacent elastic conductive components 4 is 3~5cm, which is used to correspond to the main heating area of ​​conventional household cookware. Furthermore, multiple elastic conductive components 4 are also arranged around the periphery of the first heating ring 5 to form a second heating ring 6. The diameter of the second heating ring 6 can be set to 25~30cm, for example, and the adjacent spacing is consistent with that of the first heating ring 5. A single heating ring can only cover a fixed diameter range. When a small pot is placed on it, the heating ring on the edge is empty, and when a large pot is placed on it, the heating ring in the center cannot cover the edge of the pot bottom. With the inner and outer double ring design, the small pot bottom is independently heated by the first heating ring 5, while the large pot bottom is supported by the two heating rings together, so that complete heat contact can be obtained regardless of the diameter of the pot bottom; at the same time, the independent expansion and contraction of the double rings can also cope with local deformation of the pot bottom (such as only the center protrusion or only the edge warping), and its adaptability is far superior to the single ring design.

[0041] If the heating support plate 3 adopts other shapes such as rectangle or ellipse, the first heating ring 5 and the second heating ring 6 can be set as rectangular rings, elliptical rings, etc., to ensure the uniform arrangement and heating uniformity of the elastic conduction components 4.

[0042] The heat generation component 2 (annular heating tube) is correspondingly located in the area between the first heating coil 5 and the second heating coil 6 (see reference). Figure 7 Its annular center coincides with the center of the heating support plate 3, and its radial width exactly covers the area from the outer edge of the first heating ring 5 to the inner edge of the second heating ring 6. Placing the heat source between the two heating rings achieves a "central heating, bidirectional conduction" layout. Heat radiates simultaneously from the central area to both the inner and outer sides, ensuring that the roots of the elastic conductive components 4 of the first heating ring 5 and the second heating ring 6 receive almost the same heat flux density, thus guaranteeing consistent temperatures between the inner and outer rings. If the heat source is placed directly below one of the heating rings, the temperature of that ring will be significantly higher, while the temperature of the other ring will be lower, resulting in uneven heating of the large pot bottom. This layout solves the problem of temperature difference between the two rings, and because the heat source is very close to both heating rings, the thermal response speed is fast and energy consumption is low.

[0043] The heat transfer path of this device is as follows: heat energy is transferred from the heat generation component 2 to the heating support plate 3, and then from the heating support plate 3 to each elastic conductive component 4, and then to the container to be heated. The heating support plate 3 itself serves as an intermediate heat equalization layer, which can absorb the heat radiated by the heat generation component 2 and evenly diffuse it to the entire plate surface, avoiding the direct conduction of local high temperature from the heat source to certain heat-conducting components 41 and the resulting hot spots on the bottom of the pot.

[0044] The container (pot) to be heated is placed on the heating support plate 3. Since the bottom of the pot may have concave, convex, or irregular deformations, the heat-conducting elements 41 of each elastic conductive component 4 will automatically extend and retract along the guide through structure 31 under the elastic force of the elastic element 42: at convex parts of the pot bottom, the heat-conducting element 41 is pressed downwards, and the elastic element 42 is compressed; at concave parts of the pot bottom, the heat-conducting element 41 is pushed upwards under the elastic force, always maintaining close contact with the pot bottom. Simultaneously, the first heating ring 5 and the second heating ring 6 cover the center and edge areas of the pot bottom, respectively. After the power is turned on, the annular heating tube generates heat energy, which is transferred to each elastic conductive component 4 through both the heating support plate 3 and direct radiation. Finally, the elastic conductive components 4 efficiently conduct the heat energy to all parts of the pot bottom that are in close contact with them, achieving uniform heating. Throughout the process, the cooperation between the stepped limiting hole 11 and the limiting structure 411 ensures that the heat-conducting element 41 will not detach, the preset spacing prevents the heating support plate 3 from overheating, and the multiple heating rings ensure adaptability to pot bottoms of different sizes.

[0045] Compared with existing integrated heating plates, this device completely solves the problems of uneven heating and heat loss caused by deformed pot bottoms not fitting properly and local suspension through the adaptive expansion and contraction of the elastic conduction component 4; the structural design of the heating support plate 3 as the intermediate heat equalization layer and the heat generation component 2 arranged between the two heating rings further improves the temperature uniformity; the limiting structure 411 and the guiding through structure 31 ensure the reliability and safety of long-term use.

[0046] In one embodiment, such as Figure 8 As shown, the present invention also includes a heat detection device. Specifically, the heating support plate 3 and the support base 1 are respectively provided with interconnecting through holes. The position of the through holes can be set in the central area or near the edge of the heating support plate 3 according to the actual temperature measurement needs. The heat detection device uses a temperature probe, which passes through the through holes on the heating support plate 3 and the support base 1. The upper end is close to or in contact with the bottom of the container to be heated, and the lower end can be connected to the control circuit through a wire. The heat detection device can sense the actual temperature of the bottom of the pot in real time and feed the temperature signal back to the control circuit. When the temperature of the bottom of the pot exceeds the preset safety threshold (e.g., 150°C), the control circuit can automatically cut off the power supply of the heat generation component 2 or reduce its power, thereby realizing over-temperature protection. In this embodiment, by having the temperature probe directly or nearly in contact with the bottom of the pot, the true temperature of the bottom of the pot can be reflected more accurately, thereby effectively preventing damage to the cookware, burning of food, or even the risk of fire caused by dry burning or abnormal high temperature, and improving the safety of product use.

[0047] In another embodiment, the present invention further includes a protection device (not shown) on the support base 1, which is specifically a temperature control switch. The temperature control switch is electrically connected to the heat generation component 2, and its sensing surface is in close contact with the bottom of the heating support plate 3 or a reference temperature point within the support base 1. The temperature control switch is set to a certain operating temperature (e.g., 150°C). When the ambient temperature of the heating support plate 3 or the installation space reaches this operating temperature due to abnormal conditions (such as heat accumulation caused by the sticking of the elastic conductive component 4, fan failure, etc.), the temperature control switch will automatically disconnect, cutting off the power supply circuit of the heat generation component 2. After the temperature drops to the reset temperature, the temperature control switch can be automatically or manually reset to restore power supply. This protection device serves as a primary safety protection, complementing the secondary electronic protection formed by the aforementioned heat detection device: the temperature control switch is a mechanical overheat protection, highly reliable, unaffected by electromagnetic interference, and can independently perform power-off protection when the electronic control circuit fails, thus forming a dual safety guarantee. Meanwhile, the temperature control switch has a simple structure and low cost, and is easy to integrate into the limited space of the support base 1, which helps to control the overall cost of the machine while ensuring safety.

[0048] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
