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. Utility Model Content

[0004] The utility model aims to provide a multifunctional heating plate which can select electromagnetic heating or resistance heating mode according to needs.

[0005] The purpose of the utility model is achieved in this way:

[0006] A multifunctional heating plate, comprising a high temperature resistant insulating non-magnetic furnace body, an electromagnetic generating device, a heating device, a controller, a heat insulating bottom, a heat insulating cotton heat insulating layer, a mica heat insulating layer and a ceramic seat, wherein the heating device comprises a resistance heating element and a temperature sensor, wherein the resistance heating element, the heat insulating bottom, the heat insulating cotton heat insulating layer and the mica heat insulating layer are sequentially arranged in the high temperature resistant insulating non-magnetic furnace body, the ceramic seat is arranged in the high temperature resistant insulating non-magnetic furnace body, the heating terminal of the resistance heating element is placed on the ceramic seat, and the temperature sensor is arranged on the ceramic seat;

[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 on the periphery of a high temperature resistant insulating non-magnetic furnace body, and the electromagnetic coil is arranged inside the electromagnetic coil support assembly and on the periphery of the resistance heating element;

[0008] The electromagnetic temperature control component extends outward through 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] Functional integration: By integrating the functions of induction cooker and electric ceramic cooker, it not only reduces the number of kitchen equipment, but also provides a variety of cooking methods. This integrated design allows users to choose the most suitable heating method according to specific cooking needs.

[0011] Space optimization: Since the multifunctional hotplate combines the functions of two appliances, it can significantly save space in the kitchen. This is especially important in small kitchens or when a large number of kitchen utensils are required.

[0012] Improved energy efficiency: The induction cooker heats the food using electromagnetic induction, which is extremely efficient with little heat loss, while the ceramic cooker can precisely control the heating temperature. The combined device can adjust energy use according to different cooking methods, thereby improving energy efficiency.

[0013] Simplified operation: The unified controller simplifies the operation interface and makes switching from induction heating to resistance heating simple and quick. Users can easily adjust and control cooking conditions without having to operate two independent devices separately.

[0014] Enhanced safety: The high temperature resistant, insulated and non-magnetic furnace body design improves the safety of the equipment and avoids the potential impact of heat and electromagnetic radiation on users and the kitchen environment. In addition, the thermal insulation design reduces the leakage of heat energy and reduces the risk of burns.

[0015] Good heat preservation effect: through the setting of mica sheet insulation layer and thermal insulation cotton insulation layer, it can effectively lock in heat and improve heating efficiency, while also helping to maintain the stability of cooking temperature.

[0016] Efficient heating: The combination of electromagnetic induction principle and resistance heating principle makes heating more uniform and rapid. Users can choose the appropriate heating method according to the needs of different dishes, which improves cooking efficiency.

[0017] Optimization of heating efficiency: The electromagnetic coil is placed outside the resistance heating element, which allows the electromagnetic field to act directly on the metal pot, while the resistance heating element provides radiant heat. This configuration allows the two heating mechanisms to complement each other, thereby improving the overall heating efficiency and speed.

[0018] Enhanced safety: The location of the solenoid coil helps limit direct thermal energy leakage, thereby improving safety. Induction heating does not produce open flames or hot surfaces, which further reduces the risk of burns.

[0019] Even temperature distribution: Because the electromagnetic coil surrounds the resistance heating element, it can form a more even heat distribution on the bottom and edges of the pot, which is especially important for cooking methods that require even heating, such as frying or slow cooking.

[0020] The purpose of the utility model can also be solved by the following technical measures:

[0021] Furthermore, the electromagnetic coil and the resistive heating element are at the same height.

[0022] Improved heating efficiency: The same height configuration of the electromagnetic coil and the resistance heating element allows the two heating methods to be closer in space, which helps to more effectively utilize the generated heat energy. Electromagnetic heating can quickly heat the pot to the required temperature, while resistance heating can provide stable and continuous heat, which together makes heating faster and more even.

[0023] Optimization of energy use: This layout can reduce energy waste because electromagnetic heating and resistive heating act on the same area at the same time, which improves the efficiency of energy conversion and thus reduces electrical energy consumption.

[0024] Control flexibility: Users can choose to use electromagnetic heating or resistance heating alone, or a combination of the two, to suit different cooking needs. This design allows the heating plate to be suitable for a wider variety of cooking tasks, from rapid boiling to precise temperature control cooking.

[0025] Compactness of the equipment: Due to the integrated design of the heating components, the overall equipment is more compact, reducing the required kitchen space. This is particularly beneficial in environments with limited kitchen space, allowing for better integration and layout of kitchen equipment.

[0026] Improved service life and durability: The same height design means that the thermal stress on the heating plate is more uniform, reducing material fatigue and damage due to temperature differences, thereby improving the durability and reliability of the entire equipment.

[0027] Furthermore, the resistance heating element is a heating coil.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] The beneficial effects of the utility model are as follows:

[0044] In the utility model, the induction cooker part is heated by electromagnetic induction, which is highly efficient and has almost no heat loss, while the electric ceramic stove part can accurately control the heating temperature. The integrated device can adjust energy use according to different cooking methods, thereby improving energy efficiency.

[0045] The utility model, the unified controller simplifies the operation interface, makes the switch from electromagnetic heating to resistance heating simple and quick. The user can easily adjust and control the cooking conditions without having to operate two independent devices separately.

[0046] The utility model has a high temperature resistant, insulated and non-magnetic furnace body design that improves the safety of the equipment and avoids the potential impact of heat and electromagnetic radiation on users and the kitchen environment. In addition, the heat insulation design reduces the leakage of heat energy and reduces the risk of scalding. Moreover, the mica sheet insulation layer and the heat insulation cotton insulation layer can effectively lock in heat, improve heating efficiency, and also help maintain the stability of cooking temperature.

[0047] The utility model combines the electromagnetic induction principle and the resistance heating principle to heat more evenly and quickly. Users can choose the appropriate heating method according to the needs of different dishes, which improves cooking efficiency. Moreover, the electromagnetic coil is placed on the periphery of the resistance heating element so that the electromagnetic field can directly act on the metal pot, while the resistance heating element provides radiant heat. This configuration allows the two heating mechanisms to complement each other, thereby improving the overall heating efficiency and speed.

[0048] In the utility model, the same height configuration of the electromagnetic coil and the resistance heating element allows the two heating methods to be closer in space, which helps to more effectively utilize the generated heat energy. Electromagnetic heating can quickly heat the pot to the required temperature, while resistance heating can provide stable and continuous heat, which together make heating faster and more uniform. In addition, this layout can reduce energy waste because electromagnetic heating and resistance heating act on the same area at the same time, which improves the efficiency of energy conversion and thus reduces power consumption.

[0052] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0053] Example, combined with Figure 1 to Figure 2 As shown, a multifunctional heating plate comprises a high temperature resistant insulating non-magnetic furnace body 1, an electromagnetic generating device, a heating device, a controller, a heat insulating bottom 4, a heat insulating cotton insulation layer 3, a mica sheet insulation layer 2 and a ceramic seat 11, wherein the heating device comprises a resistance heating element 5 and a temperature sensor 6, wherein the resistance heating element 5, the heat insulating bottom 4, the heat insulating cotton insulation layer 3 and the mica sheet insulation layer 2 are sequentially arranged in the high temperature resistant insulating non-magnetic furnace body 1, the ceramic seat 11 is arranged in the high temperature resistant insulating non-magnetic furnace body 1, the heating terminal 10 of the resistance heating element 5 is placed on the ceramic seat 11, and the temperature sensor 6 is arranged on the ceramic seat 11;

[0054] The electromagnetic generating device comprises an electromagnetic coil 8, an electromagnetic temperature control component 9 and an electromagnetic coil 8 support component 7, wherein the electromagnetic coil 8 support component 7 is arranged on the periphery of the high temperature resistant insulating non-magnetic furnace body 1, and the electromagnetic coil 8 is arranged inside the electromagnetic coil 8 support component 7 and is located on the periphery of the resistance heating element 5;

[0055] The electromagnetic temperature control component 9 extends outward through the high temperature resistant insulating non-magnetic furnace body 1, the mica sheet insulation layer 2, the insulation cotton insulation layer 3, the insulation bottom 4 and the resistance heating element 5, and the electromagnetic temperature control component 9 is electrically connected to the electromagnetic coil 8;

[0056] 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.

[0057] Furthermore, the electromagnetic coil 8 and the resistance heating element 5 are at the same height.

[0058] Furthermore, the resistance heating element 5 is a heating coil.

[0059] 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.

[0060] Furthermore, the shapes of the resistance heating element 5, the insulation bottom 4, the insulation cotton insulation layer 3, the mica sheet insulation layer 2, the resistance heating element 5, the electromagnetic coil 8 and the electromagnetic coil 8 bracket assembly 7 are all planes.

[0061] When the electromagnetic generator (i.e. the induction cooker solution) is started alone, the working method is as follows:

[0062] Controller activation: The user selects to start the function of the electromagnetic generating device through the controller interface. After receiving the instruction, the controller will energize the electromagnetic coil 8.

[0063] The electromagnetic coil 8 works: the controller supplies power to the electromagnetic coil 8 through an electrical connection, and the electromagnetic coil 8 begins to generate an alternating magnetic field. This magnetic field can affect the metal cookware (usually iron or iron-containing cookware) placed above.

[0064] Heat Energy Generation: Eddy currents are generated inside the metal cookware due to the magnetic field generated by the electromagnetic coil 8. The generation of these eddy currents causes the metal material to generate resistive heating, thereby heating the bottom of the cookware and the food inside.

[0065] Temperature monitoring: The electromagnetic temperature control component 9 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.

[0066] 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.

[0067] 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 8, stop heating, and safely end the working process.

[0068] In this way, the electromagnetic generating device can provide cooking functions to users efficiently and safely, and is particularly suitable for rapid heating and maintaining a cool environment in the kitchen.

[0069] When the heating device is started alone (i.e. the electric ceramic stove solution), it works as follows:

[0070] Controller activation: The user selects the function of starting the heating device 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 5.

[0071] The resistance heating element 5 works: the controller supplies power to the resistance heating element 5 through the electrical connection, and the resistance heating element 5 starts to generate heat. The resistance material inside the resistance heating element 5 is heated by the resistance generated by the current passing through, and the electrical energy is converted into heat energy.

[0072] Heat transfer: Heat is transferred from the resistance heating element 5 to the bottom of the ceramic or glass cookware placed on it. In this process, the heat insulation bottom 4, the heat insulation cotton insulation layer 3 and the mica sheet insulation layer 2 can reduce the downward conduction of heat and protect other parts of the heating plate.

[0073] Temperature monitoring: The temperature sensor 6 measures the temperature of the bottom of the ceramic or glass cookware through the ceramic base 11 and feeds the data back to the controller. The controller automatically adjusts the current of the resistance heating element 5 according to the preset temperature setting to control the heating temperature and ensure temperature stability during the cooking process.

[0074] Cooking process: As the heating device continues to heat, the food at the bottom of the pot is gradually heated, completing the cooking process. Due to the efficient heating of the resistance heating element 5, the heating speed is fast, which greatly shortens the cooking time.

[0075] 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 5, stop heating, and safely end the working process.

[0076] 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.

[0077] When the electromagnetic generator and the heating device are started at the same time (i.e. the induction cooker and the electric ceramic cooker are started together), the working method is as follows:

[0078] Controller activation: The user selects to start the electromagnetic generating device and the heating device at the same time through the controller interface. After receiving the instruction, the controller will supply power to the electromagnetic coil 8 and the resistance heating element 5 at the same time.

[0079] The electromagnetic coil 8 works: the controller supplies power to the electromagnetic coil 8 through electrical connection, and the electromagnetic coil 8 starts to generate an alternating magnetic field. This magnetic field can affect the metal cookware placed above. At the same time, the resistance heating element 5 also starts to work, generating heat through the current.

[0080] Heat generation: Due to the magnetic field generated by the electromagnetic coil 8, 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 5 also plays a role, conducting heat upward to the bottom of the ceramic or glass cookware.

[0081] Temperature monitoring: The electromagnetic temperature control component 9 and the temperature sensor 6 monitor the temperature of the induction cooker and the electric ceramic cooker respectively. The controller automatically adjusts the current of the electromagnetic generator and the heating device according to the preset temperature setting to control the heating temperature and ensure the temperature stability during the cooking process.

[0082] Cooking process: As the electromagnetic generator and the heating device continue to heat, the food at the bottom of the pot is gradually heated, completing the cooking process. 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.

[0083] 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 8 and the resistance heating element 5, stop heating, and safely end the working process.

[0084] 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.

[0085] In another embodiment, in combination Figure 3 The shapes of the resistance heating element 5, the insulation bottom 4, the insulation cotton insulation layer 3, the mica sheet insulation layer 2, the resistance heating element 5, the electromagnetic coil 8 and the electromagnetic coil 8 bracket assembly 7 are all arc-shaped.
