Description

Technical Field

[0001] The utility model relates to a multifunctional heating plate. Background Art

[0002] Traditional kitchen heating equipment usually includes induction cookers and electric ceramic cookers, which use different heating principles and structural designs to meet different cooking needs. Induction cookers use the principle of electromagnetic induction to generate a changing magnetic field through a coil to heat metal pots, while electric ceramic cookers use the principle of resistance heating to generate heat by heating ceramic or glass ceramic panels.

[0003] Although traditional induction cookers and electric ceramic cookers each have their own unique advantages, their independent designs lead to some problems. First, since they are separate heating devices, they need to be placed separately, which takes up a lot of kitchen space and is not conducive to layout and utilization. Secondly, independent control systems and heating devices increase costs and complexity. Therefore, it is necessary to propose an innovative design that combines the functions of induction cookers and electric ceramic cookers into a multifunctional heating plate to provide a more convenient and efficient heating experience.

[0007] The electromagnetic generating device comprises an electromagnetic coil, an electromagnetic temperature control assembly and an electromagnetic coil support assembly, wherein the electromagnetic coil support assembly is arranged at the bottom of the high temperature resistant insulating non-magnetic furnace body, the electromagnetic coil is arranged in the electromagnetic coil support assembly, and the electromagnetic coil is located between the electromagnetic coil support assembly and the high temperature resistant insulating non-magnetic furnace body;

[0008] The electromagnetic temperature control component extends outward through the electromagnetic coil support component, the electromagnetic coil, the high temperature resistant insulating non-magnetic furnace body, the mica sheet insulation layer, the insulation cotton insulation layer, the insulation bottom and the resistance heating element, and the electromagnetic temperature control component is electrically connected to the electromagnetic coil;

[0009] The controller is electrically connected to the electromagnetic generating device and the heating device respectively, and the controller controls the electromagnetic generating device to generate a changing magnetic field or controls the heating device to be powered on to generate heat.

[0010] Space saving: The induction cooker and ceramic cooker functions are integrated into one device, which avoids the extra space required when the two are used separately. This integrated design makes the kitchen space tidier and makes more efficient use of space resources.

[0011] Cost-effectiveness: By combining both heating methods into one unit, the cost of purchasing and installing two separate units is avoided. At the same time, maintenance and repair expenses are reduced because there is only one unit to maintain instead of two.

[0012] Flexibility: Users can choose between electromagnetic heating or resistance heating to meet the cooking needs of different dishes. This flexibility makes the heating plate more applicable to a wider range of dishes.

[0013] Optimized thermal management: The design of the built-in resistance heating element, temperature sensor, electromagnetic coil and temperature control components optimizes the overall thermal management system. The temperature sensor ensures accurate control of the heating temperature to avoid overheating or undercooking, while the insulation layer at the bottom effectively isolates heat loss and improves energy efficiency.

[0014] Wide applicability: Since the device combines two different heating principles, it can be compatible with more types of cooking utensils, from ordinary stainless steel, iron pots to ceramic or glass pots, which greatly enhances the user's freedom of choice and convenience of use.

[0015] Improved safety: The high temperature resistant insulated non-magnetic furnace body not only ensures the safety of the equipment during high temperature operation, but also prevents electromagnetic leakage and protects the health of users. At the same time, the multi-layer insulation design reduces the temperature of the high temperature resistant insulated non-magnetic furnace body, and is used to move the multi-functional heating plate to reduce the risk of burns.

[0016] The purpose of the utility model can also be solved by the following technical measures:

[0017] Furthermore, the resistance heating element is a heating coil.

[0018] Improve thermal efficiency: Using heating coils as resistive heating elements can generate heat more efficiently and transfer heat energy to cooking utensils through direct heating. This method is more efficient than other heating methods, can quickly reach the required temperature, and shorten cooking time.

[0019] Furthermore, the heating coil is wound by a strip-shaped wire core, a linear wire core, a wavy wire core, or a spring-shaped wire core.

[0020] Improved heat distribution: Different shaped wire cores can improve the distribution of heat on the stove surface based on their layout and structural characteristics. For example, wavy or spring-shaped wire cores can provide more uniform and extensive heat coverage due to their larger surface area, which is particularly beneficial for foods that require even heating during cooking, such as frying, roasting or slow cooking.

[0021] Increased mechanical elasticity: The spring-like and wavy core structure increases the elasticity of the core, making it more able to withstand thermal expansion and contraction caused by heating. This elasticity helps to extend the life of the core and reduce damage caused by thermal stress.

[0022] Optimized thermal response time: Spring-shaped and wavy wire cores may have faster thermal response time due to their complex structure. This allows the heating device to reach the required temperature faster, improving cooking efficiency and energy efficiency.

[0023] Improved heat dissipation: Ribbon and wire cores have a larger surface area in contact with the air, which helps dissipate heat and more effectively regulate temperature, thereby preventing overheating and ensuring food safety and quality during cooking.

[0024] Improved thermal efficiency: By optimizing the shape and layout of the wire core, higher thermal efficiency can be achieved and energy losses can be reduced, which is beneficial for both environmental protection and economy.

[0025] Furthermore, the shapes of the resistance heating element, the insulation bottom, the insulation cotton insulation layer, the mica sheet insulation layer, the resistance heating element, the electromagnetic coil and the electromagnetic coil bracket assembly are all planes.

[0026] Improve heat transfer efficiency: The flat shape design can better contact with the bottom of the pan, increase the contact area, and thus improve the heat transfer efficiency. This design ensures that the bottom of the pan can be heated evenly, avoiding heat concentration in a certain area of ​​the pan, thereby improving the cooking effect and the uniformity of the food.

[0027] Enhance the versatility of the equipment: The flat-shaped heating plate is very suitable for most pans on the market, which enhances the adaptability and flexibility of the heating plate. Users can use various types of pans without worrying about the compatibility between the pots and the heating plate.

[0028] Improve energy efficiency: Since the heating surface is in closer contact with the bottom of the pot, it can reduce heat loss and improve energy utilization. This design is of great significance for reducing energy consumption and saving electricity, especially in commercial kitchen environments with high energy demands.

[0029] Furthermore, the shapes of the resistance heating element, the insulation bottom, the insulation cotton insulation layer, the mica sheet insulation layer, the resistance heating element, the electromagnetic coil and the electromagnetic coil bracket assembly are all arc-shaped.

[0030] Improved compatibility with curved pots: The curved design allows the heating plate to better match the curved bottom of a pot (such as a wok or some special-purpose pots), increasing the contact area, which helps to transfer heat energy more efficiently and ensure that the bottom of the pot is heated more evenly.

[0031] Enhanced thermal efficiency: The arc design allows for closer contact, reduces heat loss, and improves energy efficiency. This design is particularly suitable for cooking methods that require high temperature and fast cooking, such as stir-frying, and can quickly transfer heat to the ingredients.

[0032] Expand the scope of use: The curved heating plate can be suitable for various types of curved pots, making this heating plate not only limited to the use of frying pans, but also more versatile and practical.

[0033] The beneficial effects of the utility model are as follows:

[0034] The utility model combines the functions of induction cooker and electric ceramic cooker into one device, avoiding the extra space required when the two are used separately. This integrated design makes the kitchen space tidier and more efficient in utilizing space resources. By integrating the two heating methods into one device, the cost of purchasing and installing two separate devices is avoided. At the same time, the cost of maintenance and repair is reduced because only one device needs to be maintained instead of two.

[0035] The utility model allows users to select electromagnetic heating or resistance heating as required to meet the cooking requirements of different dishes. This flexibility makes the heating plate more applicable and can handle more types of dishes.

[0036] The utility model optimizes the overall thermal management system by designing the built-in resistance heating element, temperature sensor, electromagnetic coil and temperature control component. The temperature sensor ensures accurate control of the heating temperature to avoid overheating or insufficient cooking, while the insulation layer at the bottom effectively isolates heat loss and improves energy efficiency.

[0040] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0041] Example, combined with Figure 1 to Figure 2As shown, a multifunctional heating plate comprises a high temperature resistant insulating non-magnetic furnace body 1, an electromagnetic generating device 7, a heating device 8, a controller, a heat insulating bottom 3, a heat insulating cotton insulation layer 4, a mica sheet insulation layer 5 and a ceramic seat 6, wherein the heating device 8 comprises a resistance heating element 81 and a temperature sensor 82, wherein the resistance heating element 81, the heat insulating bottom 3, the heat insulating cotton insulation layer 4 and the mica sheet insulation layer 5 are sequentially arranged in the high temperature resistant insulating non-magnetic furnace body 1, the ceramic seat 6 is arranged in the high temperature resistant insulating non-magnetic furnace body 1, the heating terminal of the resistance heating element 81 is placed on the ceramic seat 6, and the temperature sensor 82 is arranged on the ceramic seat 6;

[0042] The electromagnetic generating device 7 comprises an electromagnetic coil 71, an electromagnetic temperature control assembly 72 and an electromagnetic coil support assembly 73, wherein the electromagnetic coil support assembly 73 is arranged at the bottom of the high temperature resistant insulating non-magnetic furnace body 1, and the electromagnetic coil 71 is arranged in the electromagnetic coil support assembly 73, and the electromagnetic coil 71 is located between the electromagnetic coil support assembly 73 and the high temperature resistant insulating non-magnetic furnace body 1;

[0043] The electromagnetic temperature control component 72 extends outward through the electromagnetic coil support component 73, the electromagnetic coil 71, the high temperature resistant insulating non-magnetic furnace body 1, the mica sheet insulation layer 5, the insulation cotton insulation layer 4, the insulation bottom 3 and the resistance heating element 81, and the electromagnetic temperature control component 72 and the electromagnetic coil 71 are electrically connected;

[0044] The controller is electrically connected to the electromagnetic generator 7 and the heating device 8 respectively, and the controller controls the electromagnetic generator 7 to generate a changing magnetic field or controls the heating device 8 to be powered on to generate heat.

[0045] Furthermore, the resistive heating element 81 is a heating coil, which is formed by winding a plurality of first wire cores, wherein the first wire core is an iron-alloyed aluminum wire core, and the surface of the iron-alloyed aluminum wire core is coated with nano high-temperature insulating paint.

[0046] Furthermore, the shapes of the resistance heating element 81, the insulation bottom 3, the insulation cotton insulation layer 4, the mica sheet insulation layer 5, the resistance heating element 81, the electromagnetic coil 71 and the electromagnetic coil bracket assembly 73 are all planes.

[0047] When the electromagnetic generating device 7 (i.e. the induction cooker solution) is started alone, the working mode is as follows:

[0048] Controller activation: The user selects to start the function of the electromagnetic generating device 7 through the controller interface. After receiving the instruction, the controller will energize the electromagnetic coil 71.

[0049] The electromagnetic coil 71 works: the controller supplies power to the electromagnetic coil 71 through electrical connection, and the electromagnetic coil 71 starts to generate an alternating magnetic field. This magnetic field can penetrate the non-conductive high-temperature-resistant insulating non-magnetic furnace body 1 and affect the metal cookware (usually iron or iron-containing cookware) placed above.

[0050] Heat energy generation: Eddy currents are generated inside the metal cookware due to the magnetic field generated by the electromagnetic coil 71. The generation of these eddy currents causes the metal material to generate resistance heat, thereby heating the bottom of the cookware and the food inside.

[0051] Temperature monitoring: The electromagnetic temperature control component 72 passes through each layer to the pot, detects the current temperature, and feeds the data back to the controller. The controller automatically adjusts the current according to the preset temperature setting to control the heating temperature and ensure the temperature stability and safety during the cooking process.

[0052] Energy efficiency and safety: The working principle of the induction cooker makes the energy during the heating process mainly concentrated in the cooker itself, reducing the loss of ambient heat, and can quickly respond to control commands and adjust the heating intensity. At the same time, since the heat source is not directly in contact with the outside world, it is safer to use.

[0053] End of use: When cooking is completed or the user ends the cooking process, the controller will cut off the power supply to the electromagnetic coil 71, stop heating, and safely end the working process.

[0054] In this way, the electromagnetic generating device 7 can provide the user with cooking functions efficiently and safely, and is particularly suitable for rapid heating and maintaining a cool environment in the kitchen.

[0055] When the heating device 8 (i.e. the electric ceramic stove solution) is started alone, the working method is as follows:

[0056] Controller activation: The user selects to start the function of the heating device 8 through the controller interface, and this time the electric ceramic stove solution is selected. After receiving the instruction, the controller will energize the resistance heating element 81.

[0057] The resistance heating element 81 works: the controller supplies power to the resistance heating element 81 through electrical connection, and the resistance heating element 81 starts to generate heat. The resistance material inside the resistance heating element 81 is heated by the resistance generated by the current passing through, and the electrical energy is converted into heat energy.

[0058] Heat transfer: Heat is transferred from the resistance heating element 81 to the bottom of the ceramic or glass cookware placed on it. In this process, the heat insulation bottom 3, the heat insulation cotton insulation layer 4 and the mica sheet insulation layer 5 can reduce the downward conduction of heat and protect other parts of the heating plate.

[0059] Temperature monitoring: The temperature sensor 82 measures the temperature of the bottom of the ceramic or glass cookware through the ceramic base 6 and feeds the data back to the controller. The controller automatically adjusts the current of the resistance heating element 81 according to the preset temperature setting to control the heating temperature and ensure temperature stability during the cooking process.

[0060] Cooking process: As the heating device 8 continues to heat, the food at the bottom of the pot is gradually heated, and the cooking process is completed. Due to the efficient heating of the resistance heating element 81, the heating speed is fast, which greatly shortens the cooking time.

[0061] End of use: When cooking is completed or the user ends the cooking process, the controller will cut off the power supply to the resistance heating element 81, stop heating, and safely end the working process.

[0062] In this way, the electric ceramic stove solution can provide users with an efficient and safe cooking experience, and is particularly suitable for cooking needs that require low-temperature and uniform heating, such as cooking soups and stews.

[0063] When the electromagnetic generating device 7 and the heating device 8 are started simultaneously (i.e. the electromagnetic cooker and the electric ceramic cooker are started together), the working method is as follows:

[0064] Controller activation: The user selects the function of simultaneously starting the electromagnetic generating device 7 and the heating device 8 through the controller interface. After receiving the instruction, the controller will supply power to the electromagnetic coil 71 and the resistance heating element 81 at the same time.

[0065] The electromagnetic coil 71 works: the controller supplies power to the electromagnetic coil 71 through electrical connection, and the electromagnetic coil 71 starts to generate an alternating magnetic field. This magnetic field can penetrate the non-conductive high temperature resistant insulating non-magnetic furnace body 1 and affect the metal cookware placed above. At the same time, the resistance heating element 81 also starts to work and generates heat through the current.

[0066] Heat generation: Due to the magnetic field generated by the electromagnetic coil 71, eddy currents are generated inside the metal cookware, which causes the metal material to generate resistance heating, thereby heating the bottom of the cookware and the food inside. At the same time, the resistance heating element 81 also plays a role, conducting heat upward to the bottom of the ceramic or glass cookware.

[0067] Temperature monitoring: The electromagnetic temperature control assembly 72 and the temperature sensor 82 monitor the temperature of the induction cooker and the electric ceramic cooker respectively. The controller automatically adjusts the current of the electromagnetic generator 7 and the heating device 8 according to the preset temperature setting to control the heating temperature and ensure the temperature stability during the cooking process.

[0068] Cooking process: With the continuous heating of the electromagnetic generating device 7 and the heating device 8, the food at the bottom of the pot is gradually heated, and the cooking process is completed. Due to the combined effect of the induction cooker and the electric ceramic cooker, the heating speed is faster and the cooking effect is better.

[0069] End of use: When cooking is completed or the user ends the cooking process, the controller will cut off the power supply to the electromagnetic coil 71 and the resistance heating element 81, stop heating, and safely end the working process.

[0070] In this way, the joint start-up solution of induction cooker and ceramic cooker can provide users with an efficient and flexible cooking experience, meet the heating needs of different dishes, and improve cooking efficiency and quality.

[0071] Another embodiment, combined with Figure 3 As shown, the shapes of the resistance heating element 81, the insulation bottom 3, the insulation cotton insulation layer 4, the mica sheet insulation layer 5, the resistance heating element 81, the electromagnetic coil 71 and the electromagnetic coil support assembly 73 are all arc-shaped.
