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 combines the advantages of an induction cooker and an electric ceramic cooker.

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

[0006] A multifunctional heating plate comprises a furnace body, an electromagnetic generator, a heating device and a controller. The electromagnetic generator and the heating device are respectively arranged in the inner cavity of the furnace body. The controller is electrically connected to the electromagnetic generator and the heating device respectively. The controller controls the electromagnetic generator to generate a changing magnetic field or controls the heating device to generate heat by powering on.

[0007] Improved space efficiency: Combining the induction cooker and the ceramic cooker into one heating device significantly reduces the space occupied by kitchen equipment. This is especially beneficial for home kitchens or commercial kitchens with limited space, making the kitchen layout more concise and efficient.

[0008] Optimization of energy utilization: Users can choose the most suitable heating method according to different cooking needs. Electromagnetic heating is used for rapid heating and high-temperature cooking, while resistance heating is suitable for low temperature and uniform heating. This flexibility not only improves the efficiency of energy use, but also helps to preserve the nutrition and flavor of food.

[0009] Cost-effectiveness: A single control system reduces manufacturing and maintenance costs. Users do not need to purchase two devices or maintain multiple systems, which reduces the user's overall ownership and operating costs in the long run.

[0010] Easy to operate: All heating functions can be managed through one controller, making operation simpler and more intuitive. This design allows users to easily switch between different heating modes to meet various cooking needs, from fast boiling to slow cooking.

[0011] The purpose of the utility model can also be solved by the following technical measures:

[0012] Furthermore, the heating device is a heating coil, the electromagnetic generating device is a plurality of magnetic strips, the controller is electrically connected to the heating coil and the magnetic strips respectively, the controller controls the magnetic strips to generate a changing magnetic field, and the controller controls the heating coil to be energized to generate heat.

[0013] The controller can control the heating coil and magnetic strip separately to meet different cooking needs.

[0014] Fast response: The electromagnetic generator (magnetic strip) can quickly respond to the controller's instructions and quickly change the magnetic field, thereby achieving rapid heating of the pot. This fast response feature makes electromagnetic heating very suitable for cooking methods that require rapid heating and heat-off, such as stir-frying.

[0015] Energy efficiency: The combination of electromagnetic generator (magnetic strip) and heating coil can improve the overall energy efficiency. Electromagnetic heating only heats the pot when it has a metal bottom, rather than heating the entire stove surface, thus reducing energy waste. At the same time, resistance heating (heating coil) can provide stable and continuous heating when needed.

[0016] Strong adaptability: Due to the independent control of the electromagnetic generator and the resistance heating device, the heating plate can be applied to various cooking utensils, including non-magnetic utensils. This is especially useful for users who use traditional ceramic or glass pots.

[0017] Long service life and low maintenance cost: The heating coil and magnetic strip are simple and durable in design. Compared with complex electronic devices, they have a low failure rate and relatively low maintenance and replacement costs.

[0018] Easy to operate and user-friendly: The integrated control system allows users to select and adjust cooking modes through a simple interface, improving the ease of use and accessibility of the appliance.

[0019] Enhanced safety: Induction heating only works when a cooking utensil is present, avoiding the situation of heating without a pot, which increases the safety of the device and reduces the risk of burns or fire.

[0020] Furthermore, the heating coil is arranged in the furnace body, and the magnetic strip is arranged in the furnace body and below the heating coil.

[0021] Improved thermal efficiency: This layout helps the heat generated by the heating coil to be more evenly distributed on the stove surface. At the same time, the magnetic field of the magnetic strip acts upward on the metal pots on the stove surface. This structural design can reduce heat loss and improve heating efficiency.

[0022] Thermal magnetic separation: Since the heating coil is physically separated from the magnetic strip, the efficiency loss or potential magnetic degradation caused by the transfer of heat energy to the magnetic strip can be reduced. This separation ensures that the magnetic strip can operate in a relatively cool environment, maintaining its performance and life.

[0023] Enhanced magnetic field effect: Placing the magnetic strip below the heating coil helps the magnetic field act directly upward on the stove surface, which can make electromagnetic heating more concentrated and efficient, especially when using cooking utensils made of iron or other magnetic materials.

[0024] Enhanced safety: This structural design also helps to better control the thermal output and magnetic field distribution of the device, reducing the safety risks that may be caused by misoperation or equipment failure. The orderly layout of heat and magnetic sources helps prevent overheating and electromagnetic interference.

[0025] Strong cooking adaptability: This design allows users to choose the appropriate heating method according to different cooking needs. Whether it is fast heating or continuous heat preservation, it can be met by one device, which improves the flexibility and convenience of cooking.

[0026] Furthermore, the magnetic strips are arranged at intervals at the bottom of the heating coil.

[0027] Furthermore, the magnetic strip is a permanent magnet.

[0028] Furthermore, thermal insulation cotton and mica sheets are arranged between the heating coil and the furnace body.

[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 cross section of the strip-shaped core or the wavy core is a rectangle.

[0036] Furthermore, the cross section of the linear core is circular.

[0037] Furthermore, the heating coil is an arc-shaped coil, and the furnace body is an arc-shaped furnace body.

[0038] This design fits the bottom of the concave pot better and enhances heating efficiency. The arc-shaped coil can better match the curvature of the concave pot bottom, achieving more uniform heat distribution, thereby improving thermal efficiency and reducing energy waste. In addition, the arc-shaped design can also help concentrate heat energy and speed up the cooking process. At the same time, it can also better utilize the magnetic field generated by the induction cooker and optimize the interaction between the magnetic field and the pot, thereby improving the overall heating effect.

[0039] The beneficial effects of the utility model are as follows:

[0040] The utility model combines the induction cooker and the electric ceramic cooker into one heating device, which significantly reduces the space occupied by kitchen equipment. This is particularly beneficial for home kitchens or commercial kitchens with limited space, making the kitchen layout more concise and efficient, and users can choose the most suitable heating method according to different cooking needs. Electromagnetic heating is used for rapid heating and high-temperature cooking, while resistance heating is suitable for low temperature and uniform heating. This flexibility not only improves the efficiency of energy use, but also helps to retain the nutrition and flavor of food. In addition, a single control system reduces manufacturing and maintenance costs. Users do not need to purchase two devices or maintain multiple systems, which reduces the overall cost of ownership and operation of users in the long run.

[0041] In the utility model, since the heating coil is physically separated from the magnetic strip, the efficiency loss or potential magnetic reduction caused by the transfer of heat energy to the magnetic strip can be reduced. This separation ensures that the magnetic strip can operate in a relatively cold environment to maintain its performance and life, and arranging the magnetic strip below the heating coil helps the magnetic field to act directly upward on the stove surface, which can make electromagnetic heating more concentrated and efficient, especially when using cooking utensils made of iron or other magnetic materials.

[0042] In the utility model, the spring-shaped and wavy wire core structure increases the elasticity of the wire core, making it more able to withstand thermal expansion and contraction caused by heating. This elasticity helps to extend the life of the wire core and reduce damage caused by thermal stress. In addition, the spring-shaped and wavy wire core may have a faster thermal response time due to its complex structure. This allows the heating device to reach the desired temperature faster, improving cooking efficiency and energy efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
