Description

Technical Field

The utility model relates to a multifunctional heating plate.

Background

Conventional kitchen heating devices typically include induction cookers and electroceramics ovens that employ different heating principles and structural designs, respectively, to meet different cooking needs. The induction cooker uses the electromagnetic induction principle, and generates a variable magnetic field through a coil to heat the metal cookware, while the electroceramic cooker uses the resistance heating principle, and generates heat through heating ceramic or glass ceramic panels.

While conventional induction cookers and electroceramics each have their unique advantages, their independent design causes problems. First, since they are separate heating devices, they need to be placed separately, taking up a lot of kitchen space, which is detrimental to layout and utilization. Second, the separate control system and heating device add cost and complexity. Therefore, there is a need for an innovative design that combines the functions of induction cookers and electric ceramic cookers into a single multi-function heating plate to provide a more convenient and efficient heating experience.

The operation is convenient, and all heating functions can be managed through one controller, so that the operation is simpler, more convenient and more visual. The design ensures that a user can easily switch different heating modes to meet various cooking requirements from quick boiling to slow stewing.

The controller can control heating coil and magnetic stripe respectively, satisfies different culinary art demands.

The electromagnetic generating device (magnetic stripe) can quickly respond to the instruction of the controller and quickly change the magnetic field, thereby realizing the quick heating of the cooker. This rapid response characteristic makes electromagnetic heating well suited for cooking modes requiring rapid heating and heat-interruption, such as stir-frying.

Electromagnetic heating only heats up in the case of a pan with a metal bottom, not the entire oven face, thereby reducing energy waste. Meanwhile, resistance heating (heat generating coil) can provide stable continuous heating when necessary.

The heating plate is suitable for various cooking appliances, including non-magnetic appliances, due to the independent control of the electromagnetic generating device and the resistance heating device. This is particularly useful for users using conventional ceramic or glass cookware.

Thermomagnetic separation-due to the physical separation of the heat generating coil from the magnetic stripe, efficiency losses or potential magnetic degradation due to the transfer of thermal energy to the magnetic stripe can be reduced. This separation ensures that the magnetic stripe can operate in a relatively cold environment, maintaining its performance and longevity.

The magnetic field is enhanced, namely the magnetic strip is arranged below the heating coil, so that the magnetic field is directly acted on the stove surface upwards, and electromagnetic heating can be more concentrated and efficient, especially when a cooking appliance made of iron or other magnetic materials is used.

Improved heat distribution characteristics-different shaped cores can improve the distribution of heat on the furnace face according to the layout and structural characteristics thereof. For example, a wavy or spring-like core may provide more uniform and broad thermal coverage due to its greater surface area, which is particularly beneficial for foods requiring uniform heating during cooking (e.g., grilling or slow stewing).

The increased mechanical elasticity-the spring-like and wave-like core structure increases the elasticity of the core, making it more resistant to thermal expansion and contraction due to heating. This elasticity helps to extend the life of the core and reduce damage caused by thermal stresses.

Optimized thermal response time-spring-like and wave-like cores may have faster thermal response times due to their complex structure. This allows the heating device to reach the desired temperature faster, improving cooking efficiency and energy use efficiency.

The improved heat dissipation capability is that the strip-shaped and linear wire cores have larger surface areas to be contacted with air, which is helpful for heat dissipation and more effective temperature regulation, thereby preventing overheating and ensuring the safety and quality of food in the cooking process.

Improved thermal efficiency by optimizing the shape and layout of the wire core, higher thermal efficiency can be achieved, and energy loss is reduced, which is beneficial to environmental protection and economy.

Further, the cross section of the strip-shaped wire core or the wavy wire core is rectangular.

Further, the cross section of the linear wire core is circular.

Further, the heating coil is an arc-shaped coil, and the furnace body is an arc-shaped furnace body.

The design is more attached to the bottom of the concave pot, so that the heating efficiency is enhanced. The arc-shaped coil can be better matched with the curvature of the concave bottom of the pan, so that more uniform heat distribution is realized, thereby improving the heat efficiency and reducing the energy waste. In addition, the arc-shaped design can also help to concentrate heat energy and accelerate the cooking process, and meanwhile, the magnetic field generated by the induction cooker can be better utilized, so that the interaction between the magnetic field and the cooker is optimized, and the overall heating effect is improved.

The user does not have to purchase two devices and maintain multiple systems, which reduces the overall ownership and operating costs of the user in the long term.

According to the utility model, the heating coil is physically separated from the magnetic stripe, so that the efficiency loss or potential magnetic reduction caused by heat energy transfer to the magnetic stripe can be reduced. This separation ensures that the magnetic strip can operate in a relatively cold environment, maintaining its performance and longevity, and that the positioning of the magnetic strip below the heat-generating coil helps the magnetic field to act directly upward on the cooking surface, which can make electromagnetic heating more concentrated and efficient, especially when cooking appliances made of iron or other magnetic materials are used.

According to the utility model, the spring-shaped and wave-shaped wire core structure increases the elasticity of the wire core, so that the wire core can bear thermal expansion and contraction caused by heating. This elasticity helps to extend the life of the core, reduce damage caused by thermal stresses, and the spring-like and wave-like cores may have a faster thermal response time due to their complex structure. This allows the heating device to reach the desired temperature faster, improving cooking efficiency and energy use efficiency.
