Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking pot technology, and in particular to a multifunctional cooking pot waterproof baking tray structure. Background Technology
[0002] Currently, the common method for connecting the baking pan and heating plate of a separate cooking pot involves die-casting the baking pan and then riveting the heating plate onto it. In this structure, the heating plate is usually exposed and fixed to the baking pan only by a simple mechanical connection, lacking effective sealing and protection measures.
[0003] In actual use, especially in the cleaning of the baking pan, numerous problems have been exposed, seriously affecting the user experience. Due to their structural design and technological limitations, existing detachable cooking pot baking pans are extremely inconvenient to clean. Users cannot soak the baking pan in water or put it directly in a dishwasher; they can only use a conservative and cumbersome wiping method. This cleaning method not only fails to thoroughly remove grease and food residue from the baking pan, increasing the difficulty and workload of cleaning, but may also lead to bacterial growth due to incomplete cleaning, affecting the hygiene and safety of cooked food. Utility Model Content
[0004] The purpose of this utility model is to disclose a multifunctional cooking pot waterproof baking pan structure. By integrally die-casting the baking pan and the heating plate, only the conductive rod at the end of the heating plate is exposed, which can be completely immersed in water for cleaning, greatly improving the waterproofness of the baking pan.
[0005] To achieve the above objectives, this utility model discloses a multifunctional cooking pot waterproof baking pan structure, comprising: a base, wherein a plug-in unit is provided on the top surface of the base; a heating plate, wherein silicone caps and conductive rods are symmetrically arranged at both ends of the heating plate and are sequentially sealed and connected, wherein the conductive rods are plugged into and electrically connected to the plug-in unit; and a baking pan body, wherein the bottom of the baking pan body is integrally die-cast with the heating plate, and the baking pan body is detachably connected to the base.
[0006] By adopting the above solution, the baking pan and heating plate are integrally die-cast, with the heating plate completely embedded inside the baking pan, only the conductive rod at the end of the heating plate protruding. This structure makes the baking pan seamless, allowing it to be directly immersed in water for washing or placed in a dishwasher, thoroughly removing oil stains and food residue, improving cleaning efficiency and hygiene safety. The embedded tube die-casting process completely encapsulates the heating plate inside the baking pan, avoiding direct contact with air and moisture, preventing oxidation and corrosion. Simultaneously, the two ends of the heating plate are sealed to the conductive rod via silicone caps, further preventing moisture intrusion, protecting the heating plate and circuit system, and extending service life. It also eliminates the mechanical connection between the heating plate and the baking pan, no longer relying on the dimensional accuracy of individual components. The sealed connection design between the conductive rod and the plug-in unit also reduces assembly difficulty and improves the overall structural stability and success rate.
[0007] Furthermore, a heating wire is centrally disposed within the heating plate, and a heating tube cold needle extending from the end of the heating plate is connected to the end of the heating wire. The heating plate is filled with magnesium oxide filler that encapsulates the heating wire and the heating tube cold needle.
[0008] By adopting the above scheme, the heating wire is centrally positioned within the heating plate, allowing heat to diffuse evenly outwards from the center. This uniform heat distribution ensures minimal temperature differences across the baking pan when heating food, preventing localized overheating or underheating, guaranteeing even heating, and resulting in better cooking outcomes and improved food quality and taste. Magnesium oxide, an excellent insulating material with good thermal conductivity, effectively prevents electrical short circuits between the heating wire and the external environment, thus preventing electrical leakage.
[0009] Furthermore, a hollow section is provided near the end of the heating plate, and the hollow section is filled with a first high-temperature silicone for fixing the magnesium oxide filler and the heating tube cold needle, and the first high-temperature silicone is aligned with the port of the heating plate.
[0010] By employing the above scheme, the magnesium oxide filler encapsulates the heating wire and heating tube cold needle. During the operation of the heating plate, slight movement may occur due to factors such as temperature changes and vibration. The first high-temperature silicone filling within the hollowed-out section provides additional fixation for the magnesium oxide filler, binding it more tightly within the heating plate and preventing it from loosening or shifting. This ensures that the heating wire and heating tube cold needle remain in a stable position, maintaining the normal heating performance of the baking plate. The first high-temperature silicone filling within the hollowed-out section tightly encapsulates the heating tube cold needle, enhancing the connection strength between the heating tube cold needle and the heating plate. This prevents the heating tube cold needle from loosening or falling off due to shaking or pulling during use, improving the reliability of the electrical connection. The heating plate port is a critical area where external moisture may enter the heating plate. The first high-temperature silicone filling is aligned with the heating plate port, forming a tight waterproof barrier that effectively prevents moisture from seeping into the heating plate from the port. This meets the requirements for water immersion.
[0011] Furthermore, the silicone cap is sealed and fixed to the end of the heating plate by a second high-temperature silicone seal, and the heating tube cold needle passes through the silicone cap and is fixedly connected to the conductive rod.
[0012] By adopting the above solution, the second high-temperature silicone sealant forms a tight sealing layer between the silicone cap and the end of the heating plate, effectively preventing moisture from seeping into the heating plate from the connection between the end of the heating plate and the silicone cap. Simultaneously, the silicone cap itself possesses a certain degree of elasticity and sealing properties, working in conjunction with the second high-temperature silicone sealant to form a double waterproof mechanism. This significantly enhances the overall waterproof performance of the baking pan, ensuring that the heating wire, magnesium oxide filler, and other electrical components inside the heating plate will not be damaged by water ingress when immersed in water for cleaning or in a humid environment.
[0013] Furthermore, the heating tube cold needle is provided with external threads, the conductive rod is provided with internal threads, and the heating plate is threadedly connected to the conductive rod to lock the silicone cap.
[0014] By adopting the above solution, the threaded connection is a connection method with good self-locking properties. During the tightening process, an inward squeezing force is generated on the silicone cap, pressing it tightly against the end of the heating plate. When the heating element's cold needle and the conductive rod are screwed together, a large frictional force and mechanical interlocking force are generated between them, making the connection very strong. This squeezing force makes the seal between the silicone cap and the end of the heating plate even tighter, further enhancing the waterproof performance.
[0015] Furthermore, the conductive rod and the heating plate are riveted together.
[0016] By adopting the above scheme, when the conductive rod and the heating plate are riveted, the rivet undergoes plastic deformation during the riveting process, tightly pressing the conductive rod and the heating plate together to form a strong mechanical connection. This connection method can withstand greater tensile force, shear force, and vibration. During the use of the baking pan, even when encountering frequent handling, thermal expansion and contraction stress generated by heating and cooling cycles, the conductive rod and the heating plate are not prone to loosening or separation, ensuring the stability and reliability of the connection.
[0017] Furthermore, the bottom of the baking pan body is provided with a protruding assembly structure, and the assembly structure is provided with a channel for accommodating the heating plate, the heating plate being embedded in the channel.
[0018] By adopting the above solution, the heating plate is evenly embedded within the channel, allowing for more even heat distribution across the bottom of the baking pan. During heating, heat diffuses from the heating plate outwards, preventing localized overheating or underheating and ensuring a more uniform temperature distribution on the baking pan surface. This ensures that all parts of the food are heated evenly during cooking, guaranteeing optimal results and enhancing the taste and color of the food. Whether frying, grilling, or baking, the food achieves ideal cooking conditions. The protruding assembly structure provides physical protection for the heating plate, preventing damage from collisions, pressure, or other external forces during transportation, installation, and use. The embedded heating plate within the channel facilitates the implementation of waterproofing measures.
[0019] Furthermore, the plug-in unit includes a first socket guide plate, a second socket guide plate, and a third socket guide plate. The first and second socket guide plates are respectively plugged into and connected to the conductive rod at the end of the heating plate, and the third socket guide plate is used to plug into and connect to the ground wire guide plate extending from the bottom of the baking pan body.
[0020] By adopting the above solution, a tight physical contact can be formed between the conductive plate and the conductive rod. This ensures that the conductive plate has a certain clamping force on the conductive rod in the plugged-in state, thereby ensuring the stability of current transmission, reducing problems such as increased resistance and abnormal heating caused by poor contact, and lowering the probability of electrical faults. The plug-in connection method is simple to operate and requires no complicated tools or professional skills. During the production and assembly of the baking tray, workers can quickly and accurately insert the conductive rod into the corresponding socket conductive plate, improving production efficiency. At the same time, when the baking tray needs to be repaired, or the heating plate or other components need to be replaced, the conductive rod can be easily pulled out of the socket conductive plate, facilitating maintenance and upkeep.
[0021] Furthermore, the baking pan body is provided with multiple support feet, the ends of the support feet are on the same plane, and a temperature control boss is provided on the bottom of the baking pan body near the assembly structure, the height of the temperature control boss not exceeding the height of the support feet.
[0022] By adopting the above solution, the ends of multiple support feet are on the same plane, providing a stable and level support surface for the baking pan. The temperature control boss is positioned close to the assembly structure, allowing it to be closer to the core heating area of the baking pan. This enables more accurate sensing of temperature changes at the bottom of the baking pan. By detecting the temperature of the temperature control boss, the heating power of the heating plate can be controlled in a timely and precise manner, achieving accurate temperature adjustment of the baking pan to meet different cooking needs.
[0023] Furthermore, the base is also provided with a socket switch slider, which is used to control the start and stop of the heating plate.
[0024] By adopting the above solution, the operation of the socket switch slider is very intuitive. Users can control the heating plate to start and stop with a simple sliding motion.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0026] 1. The baking pan and heating plate are integrally die-cast, with the heating plate fully embedded inside the pan, only the conductive rod at the end of the heating plate protruding. This makes the baking pan seamless, allowing it to be directly soaked in water for cleaning, more thoroughly removing grease and food residue, greatly improving cleaning efficiency. In addition to soaking, this baking pan structure can also be placed in a dishwasher. This is a huge convenience for users who value a convenient lifestyle, saving time and effort compared to manual cleaning, further enhancing the user experience.
[0027] 2. The one-piece die-cast structure eliminates the gaps and dead corners caused by the riveting of the heating plate in traditional baking pans, preventing the accumulation of oil and food residue in these areas, making cleaning easier and more thorough, and effectively ensuring the hygiene and safety of the baking pan. The one-piece structure enhances the overall strength and rigidity of the baking pan, allowing it to better withstand the stress generated by thermal expansion and contraction during heating and cooling, making it less prone to deformation and cracking, thus ensuring the normal use and aesthetic appearance of the baking pan.
[0028] 3. The embedded tube die-casting process completely encapsulates the heating plate inside the baking pan, significantly reducing the chance of direct contact between the heating plate and external air and moisture. This physical isolation effectively prevents moisture from entering the heating plate, avoiding electrical faults such as short circuits and leakage caused by moisture, and improving the waterproof performance of the baking pan. Both ends of the heating plate are sealed to the conductive rods via silicone caps, forming a reliable waterproof barrier. The silicone caps have good elasticity and sealing properties, allowing them to fit tightly against the conductive rods, further preventing moisture from entering at the connection between the conductive rods and the heating plate, providing double protection for the heating plate and the electrical system.

[0042] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0043] Please refer to Embodiment 1 of this utility model. Figures 1 to 6As shown, a multi-functional cooking pot waterproof baking pan structure is provided, including a base 1, a heating plate 2, and a baking pan body 3. A plug-in unit 11 is centrally located on the top surface of the base 1. This location can be different in other embodiments, but is not specifically limited in this embodiment. In this embodiment 1, the plug-in unit 11 comprises a first socket guide 111, a second socket guide 112, and a third socket guide 113, which are spaced apart from each other. The third socket guide 113 is used to connect with a ground wire guide 33 extending from the bottom of the baking pan body 3. The heating plate 2 is formed by bending a metal tube, including but not limited to U-shape, S-shape, straight shape, or serpentine shape. The metal tube of the heating plate 2 is preferably a stainless steel tube. A heating wire 23 is centrally inserted inside the heating plate 2. The heating wire 23 can be a nickel-chromium alloy heating wire 23. The central placement of the heating wire 23 within the heating plate 2 allows heat to diffuse evenly outwards from the center of the heating plate 2. This uniform heat distribution ensures minimal temperature differences across the baking pan when heating food, preventing localized overheating or cooling and guaranteeing even heating for better cooking results, thus enhancing the quality and taste of the dish. Magnesium oxide, an excellent insulator with good thermal conductivity, encapsulates the heating wire 23 and the heating element cooling needle 24, effectively preventing electrical short circuits between the heating wire 23 and the external environment, thus preventing electrical leakage.
[0044] The heating wire 23 is connected to heating tube cold needles 24 at both ends. The heating tube cold needles 24 protrude from the end of the heating plate 2. The heating tube cold needles 24 can be made of the same material as brass. The heating plate 2 is filled with high-purity magnesium oxide powder 27 so that the heating wire 23 and the heating tube cold needles 24 in the heating plate 2 are completely wrapped by the magnesium oxide powder 27 filler. After vibration and sintering, a dense insulating and heat-conducting layer is formed. The heating plate 2 has hollowed-out sections 25 at both ends, with a hollowed-out size of 4mm-5mm. The hollowed-out sections 25 are filled with a first high-temperature silicone 26 that can withstand temperatures up to 300℃. The first high-temperature silicone 26 can be red high-temperature silicone, which has good insulation and indication effects. After the first high-temperature silicone 26 is cured, it is flush with the tube opening. The magnesium oxide filler wraps around the heating wire 23 and the heating tube cold needles 24. During the operation of the heating plate 2, there may be slight movement due to temperature changes, vibration, and other factors. The high-temperature silicone 26 filling the hollow section 25 provides additional fixation for the magnesium oxide filler, binding it more tightly within the heating plate 2 and preventing it from loosening or shifting. This ensures that the heating wire 23 and the heating tube cold needle 24 remain in a stable position, maintaining the normal heating performance of the baking pan. The high-temperature silicone 26, filling the hollow section 25, tightly wraps the heating tube cold needle 24, enhancing the connection strength between the heating tube cold needle 24 and the heating plate 2. This prevents the heating tube cold needle 24 from loosening or falling off during use due to shaking or pulling, improving the reliability of the electrical connection. The ports of the heating plate 2 are critical areas where external moisture may enter. The high-temperature silicone 26 is aligned and filled with the ports of the heating plate 2, forming a tight waterproof barrier that effectively prevents moisture from seeping into the heating plate 2 from the ports, meeting the requirements for water immersion.
[0045] The heating plate 2 has silicone caps 21 and conductive rods 22 symmetrically arranged at both ends and sealed in sequence. The conductive rods 22 are electrically connected to the plug-in unit 11. The bottom of the baking pan body 3 is integrally die-cast with the heating plate 2, and the baking pan body 3 is detachably connected to the base 1. Specifically, the two conductive rods 22 are respectively plugged into the first socket guide plate 111 and the second socket guide plate 112. The bottom of the baking pan body 3 has an outwardly protruding assembly structure 31, and the assembly structure 31 has a channel 32 for accommodating the heating plate 2. The heating plate 2 is embedded in the channel 32, and the evenly embedded heating plate 2 can make the heat more evenly transferred to all areas of the bottom of the baking pan. During the heating process, the heat diffuses from the heating plate 2 to the surrounding area, avoiding local overheating or undercooling, and making the surface temperature distribution of the baking pan more uniform. In this way, when cooking food, all parts of the food are heated evenly, which can ensure the cooking effect, improve the taste and color of the food, and achieve the ideal cooking state whether frying, grilling or baking. The protruding assembly structure 31 provides physical protection for the heating plate 2, preventing it from being damaged by external forces such as collisions and squeezing during transportation, installation, and use. The heating plate 2 is embedded in the channel 32, which facilitates the implementation of waterproofing measures.
[0046] The silicone cap 21 is sealed and fixed to the end of the heating plate 2 by a second high-temperature silicone sealant 4. The heating tube cold needle 24 passes through the silicone cap 21 and is fixedly connected to the conductive rod 22. Preferably, the heating tube cold needle 24 is provided with external threads, and the conductive rod 22 is provided with internal threads. The heating plate and the conductive rod 22 are threadedly connected to lock the silicone cap 21. Threaded connection is a connection method with good self-locking properties. During tightening, an inward squeezing force is generated on the silicone cap 21, pressing the silicone cap 21 tightly against the end of the heating plate 2. When the heating tube cold needle 24 and the conductive rod 22 are screwed together, a large frictional force and mechanical interlocking force are generated between them, making the connection very firm. This squeezing force makes the seal between the silicone cap 21 and the end of the heating plate 2 even tighter, further enhancing the waterproof performance.
[0047] In some embodiments, to further improve the connection stability of the conductive rod 22, the conductive rod 22 and the heating plate 2 are riveted together. This connection method can withstand greater tensile force, shear force, and vibration. During the use of the baking pan, even if it encounters frequent handling, thermal expansion and contraction stress caused by heating and cooling cycles, the conductive rod 22 and the heating plate 2 are not easily loosened or separated, ensuring the stability and reliability of the connection. The baking pan body 3 and the heating plate 2 are integrally die-cast, with the heating plate 2 completely embedded inside the baking pan, only the conductive rod 22 at the end of the heating plate 2 is exposed. This structure makes the baking pan seamless, allowing it to be directly soaked in water for washing or placed in a dishwasher, thoroughly removing oil stains and food residue, improving cleaning efficiency and hygiene safety. The embedded tube die-casting process completely encloses the heating plate 2 inside the baking pan, avoiding direct contact with air and moisture, preventing oxidation and corrosion. At the same time, the two ends of the heating plate 2 are sealed to the conductive rod 22 through silicone caps 21, further preventing moisture intrusion, protecting the heating plate 2 and the circuit system, and extending service life. It also eliminates the mechanical connection link between the heating plate 2 and the baking pan, no longer relying on the dimensional accuracy of individual components. The sealed connection design between the conductive rod 22 and the plug-in unit 11 also reduces the assembly difficulty and improves the stability and success rate of the overall structure.
[0048] In some embodiments, the bottom of the baking pan body 3 is further provided with multiple support feet 34, the ends of which are on the same plane. A temperature control boss 35 is provided near the assembly structure 31 at the bottom of the baking pan body 3. The height of the temperature control boss 35 does not exceed the height of the support feet 34. The ends of the multiple support feet 34 are on the same plane, providing a stable and level support surface for the baking pan. The proximity of the temperature control boss 35 to the assembly structure 31 allows it to be closer to the core heating area of the baking pan, thus more accurately sensing temperature changes at the bottom of the baking pan. By detecting the temperature of the temperature control boss 35, the heating power of the heating plate 2 can be controlled in a timely and precise manner, achieving precise temperature adjustment of the baking pan to meet different cooking needs. In this embodiment 1, four stainless steel support feet 34 are welded to the bottom of the baking pan body 3, with a coplanar tolerance of ≤0.2mm at the foot ends. The height of the temperature control boss 35 is at least 1.5mm lower than the end face of the support feet 34.
[0049] In some embodiments, optionally, a socket switch slider 12 is also provided on the base 1. The socket switch slider 12 is used to control the start and stop of the heating plate 2. It is linked with a micro switch through an internal slide rail to control the on and off of the heating plate 2. The operation of the socket switch slider 12 is very intuitive. Users can control the start and stop of the heating plate 2 with a simple sliding action.
[0050] During assembly, the baking pan body 3 is placed on the base 1 via support feet 34. Two conductive rods 22 are inserted into the elastic clamping grooves of the first socket guide plate 111 and the second socket guide plate 112, which are spaced apart, to complete the electrical connection. The ground wire guide plate 33 is inserted into the third socket guide plate 113 to ensure grounding safety. The socket switch slider 12 is slid to the "ON" position, and the current flows through the guide plates, through the conductive rods 22, and reaches the heating wire 23 to generate heat. The heat is then conducted through the magnesium oxide layer to the aluminum alloy baking pan for uniform heat conduction. During cleaning, the baking pan can be removed and immersed in water or placed in a dishwasher. The silicone cap 21 and double high-temperature silicone prevent moisture intrusion, and the magnesium oxide layer maintains insulation.
[0051] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0052] 1. The baking pan body 3 and the heating plate 2 are integrally die-cast, with the heating plate 2 completely embedded inside the baking pan, only the conductive rod 22 at the end of the heating plate 2 protruding. This makes the baking pan seamless, allowing it to be directly soaked in water for cleaning, more thoroughly removing oil stains and food residue, greatly improving cleaning efficiency. In addition to soaking in water, this baking pan structure can also be placed directly in a dishwasher. This is a great convenience for users who value a convenient lifestyle, saving time and effort compared to manual cleaning, further enhancing the user experience.
[0053] 2. The one-piece die-cast structure eliminates the gaps and dead corners caused by the riveting of the heating plate 2 in traditional baking pans, preventing the accumulation of oil and food residue in these areas, making cleaning easier and more thorough, and effectively ensuring the hygiene and safety of the baking pan. The one-piece structure enhances the overall strength and rigidity of the baking pan, and during the heating and cooling process, the baking pan can better withstand the stress generated by thermal expansion and contraction, and is not prone to deformation, cracking and other problems, ensuring the normal use and beautiful appearance of the baking pan;
[0054] 3. The embedded tube die-casting process completely encloses the heating plate 2 inside the baking pan, significantly reducing the chance of direct contact between the heating plate 2 and external air and moisture. This physical isolation method effectively prevents moisture from entering the heating plate 2, avoiding electrical faults such as short circuits and leakage caused by moisture, and improving the waterproof performance of the baking pan. The two ends of the heating plate 2 are sealed to the conductive rod 22 via silicone caps 21, forming a reliable waterproof barrier. The silicone caps 21 have good elasticity and sealing properties, allowing them to fit tightly against the conductive rod 22, further blocking the possibility of moisture entering from the connection between the conductive rod 22 and the heating plate 2, providing double protection for the heating plate 2 and the circuit system.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
