Description

Technical Field

[0001] The utility model relates to a coil and a stove with the functions of generating a magnetic field and generating heat. Background Art

[0002] Traditional induction cookers and electric ceramic cookers are common heating devices in the kitchen. They each use different heating principles and control systems to meet different cooking needs. Induction cookers heat metal pots through the principle of electromagnetic induction, while electric ceramic cookers heat ceramic or glass ceramic panels through the principle of resistance heating to generate heat. Although they differ in heating principles, they each have a series of advantages, such as the rapid heating, high energy efficiency, and controllable temperature of induction cookers, which are suitable for fast cooking; while electric ceramic cookers have the characteristics of uniform heating and uniform temperature distribution, which are suitable for long-term slow cooking.

[0003] However, traditional induction cookers and electric ceramic cookers are usually designed independently, which results in the heating plates taking up a large space and needing to be placed separately when in use, which is not flexible enough and is not conducive to the rational use and layout of kitchen space. In addition, they also require their own independent control systems and heating devices, which increases costs and complexity. Utility Model Content

[0004] The first object of the utility model is to provide a coil having the functions of generating a magnetic field and generating heat.

[0005] The second object of the utility model is to provide a stove which has a coil with the function of generating a magnetic field and generating heat and realizes the integration of the functions of an induction cooker and an electric ceramic cooker.

[0006] The first purpose of the utility model is achieved in this way:

[0007] A coil with the function of generating a magnetic field and generating heat, the coil comprises a wire core with the function of generating a magnetic field and generating heat, the wire core is a strip-shaped wire core, a linear wire core, a spring-shaped wire core or a wavy wire core, and the surface of the wire core is coated with nano high-temperature insulating paint.

[0008] Improve energy efficiency and heating efficiency: By combining the principles of electromagnetic induction and resistance heating, the coil can more efficiently convert electrical energy into heat energy. For induction cookers, electromagnetic induction can quickly heat iron or magnetic pots; while for scenes that require even heating, such as electric ceramic stoves, resistance heating can provide more uniform heat distribution.

[0009] Improved high temperature resistance: The nano high temperature insulating paint coated on the surface of the wire core not only protects the wire core from direct high temperature damage, increases the durability and life of the coil, but also prevents short circuits and electrical safety accidents.

[0010] Expanded cooking flexibility: Users can choose to use electromagnetic heating or resistance heating, or a combination of the two, according to different cooking needs. This flexibility allows the same device to be used for a variety of cooking methods, such as quickly stir-frying vegetables, boiling water, and slow-cooking soups.

[0011] Increase the surface area of ​​the coil: Linear, spring-shaped or wavy designs can effectively increase the surface area of ​​the coil in contact with the air or pot, thereby improving the heat exchange efficiency. In particular, the spring-shaped iron-alloy aluminum wire core, its unique shape can produce a larger surface area, making the heat more evenly distributed.

[0012] Improve the strength and uniformity of the magnetic field: Due to its shape, the spring-shaped, linear or wavy core can generate a more uniform magnetic field when current passes through it. This is especially important for induction cookers, because a more uniform magnetic field can effectively improve heating efficiency and consistency in food cooking.

[0013] Enhanced mechanical strength and flexibility: The spring-shaped or wavy iron-aluminum wire core has better mechanical strength and flexibility, making the coil more durable and reducing physical loss caused by long-term use and thermal expansion.

[0014] Improved heat dissipation: The linear and spring-shaped structure design helps to dissipate heat from the coil, thereby reducing energy waste and potential damage risks caused by overheating.

[0015] The first purpose of the utility model can also be solved by the following technical measures:

[0016] Furthermore, the cross section of the strip core is rectangular.

[0017] Furthermore, the cross section of the linear core is circular.

[0018] Further, the strip-shaped wire core is a strip-shaped iron-clad aluminum wire core, the line-shaped wire core is a line-shaped iron-clad aluminum wire core, the spring-shaped wire core is a spring-shaped iron-clad aluminum wire core, and the wavy wire core is a wavy iron-clad aluminum wire core.

[0019] Optimize electrothermal performance: The material of iron-alloy aluminum combined with nano high-temperature insulating paint can effectively control the efficiency and safety of electrothermal conversion. The linear or spring-like shape helps to optimize the resistance characteristics of the coil and achieve more efficient electrothermal conversion.

[0020] The second purpose of the utility model is achieved in this way:

[0021] A stove comprises a high temperature resistant, insulated and non-magnetic stove body and a controller. The coil is placed in the inner cavity of the stove body. The controller is electrically connected to the coil. The controller controls the coil to generate a changing magnetic field or controls the coil core to generate heat by energizing.

[0022] Efficient heating performance: The controller can selectively control the coil to generate a changing magnetic field or generate heat by energizing the iron-alloy aluminum wire core. This flexible heating method allows the stove to adapt to different cooking needs, such as fast heating and uniform heating.

[0023] Enhanced safety: The high-temperature resistant, insulated and non-magnetic furnace body can effectively prevent heat loss, while preventing interference from external magnetic fields, protecting electrical components from high temperatures, and enhancing safety in use.

[0024] Multifunctional and integrated design: The design of this stove can not only adapt to traditional cooking methods, but also meet the needs of modern kitchens for multifunctionality and high efficiency. For example, different cooking methods such as boiling, frying and stewing can be performed on the stove at the same time.

[0025] The second purpose of the utility model can also be solved by the following technical measures:

[0026] Furthermore, the coil is an arc-shaped coil, and the furnace body is an arc-shaped furnace body.

[0027] 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.

[0028] The beneficial effects of the utility model are as follows:

[0029] The utility model combines the principles of electromagnetic induction and resistance heating to convert electrical energy into heat energy more efficiently. For the induction cooker, electromagnetic induction can quickly heat iron or magnetic pots; and for scenes that require even heating, such as electric ceramic stoves, resistance heating can provide more even heat distribution.

[0030] In the utility model, the nanometer high temperature insulating paint coated on the surface of the wire core not only protects the wire core from direct high temperature damage, increases the durability and life of the coil, but also prevents the occurrence of short circuits and electrical safety accidents.

[0031] In the present invention, the spring-shaped or line-shaped core can generate a more uniform magnetic field when current passes through it due to its shape characteristics. This is particularly important for the application of induction cookers, because a more uniform magnetic field can effectively improve the heating efficiency and the consistency of food cooking.

[0032] The utility model adopts a spring-shaped iron-alloy aluminum wire core with better mechanical strength and flexibility, making the coil more durable and reducing physical loss caused by long-term use and thermal expansion; and the linear and spring-shaped structural design helps to dissipate heat of the coil, thereby reducing energy waste and potential damage risks caused by overheating.

[0033] In the utility model, the controller can selectively control the coil to generate a changing magnetic field or generate heat by electrifying the iron-alloy aluminum wire core. This flexible heating method enables the stove to adapt to different cooking needs, such as rapid heating and uniform heating. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0043] Example, combined with Figures 1 to 7 As shown, a coil with the function of generating a magnetic field and generating heat, the coil 1 includes a wire core with the function of generating a magnetic field and generating heat, the wire core 2 is a strip-shaped iron-clad aluminum wire core, a linear iron-clad aluminum wire core, a spring-shaped iron-clad aluminum wire core or a wavy iron-clad aluminum wire core, and the surface of the wire core 2 is coated with nano high-temperature insulating paint.

[0044] Furthermore, the cross-section of the strip-shaped iron-clad aluminum wire core or the wavy iron-clad aluminum wire core is rectangular.

[0045] Furthermore, the cross-section of the linear iron-alloy aluminum core is circular.

[0046] A furnace using the coil 1 includes a high-temperature resistant, insulated, non-magnetic furnace body 3 and a controller. The coil 1 is placed in the inner cavity of the furnace body 3. The controller and the coil 1 are electrically connected. The controller controls the coil 1 to generate a changing magnetic field or controls the iron-alloy aluminum wire core 2 of the coil 1 to be energized to generate heat.

[0047] The core of this stove is a coil that has the function of generating magnetic field and heat. The coil is wound with multiple strands of wire cores, which can be strip-shaped iron-clad aluminum wire cores, linear iron-clad aluminum wire cores, spring-shaped iron-clad aluminum wire cores or wavy iron-clad aluminum wire cores. The surface of these wire cores is coated with nano high-temperature insulating paint to improve the high-temperature resistance of the coil.

[0048] In this induction cooker, we take the strip iron-coated aluminum wire core as an example, which has a rectangular cross-section. When the user activates the induction function, the controller will control the coil through electrical connection to generate a changing magnetic field. The changing magnetic field generated by the flow of current in the coil will induce eddy currents at the bottom of the pot, causing the pot to generate magnetic coupling and heat up quickly. This fast heating feature allows users to quickly heat ingredients to the desired temperature, saving time and improving cooking efficiency.

[0049] This stove is characterized by its ability to generate magnetic field and heat. The coil is wound with multiple strands of wire cores, which are spring-shaped iron-alloy aluminum wire cores, and the surface is coated with nano high-temperature insulating paint to enhance the high temperature resistance of the coil.

[0050] When the user activates the heating function, the controller energizes the iron-and-aluminum wire core of the control coil through the electrical connection, causing it to generate heat. The design of the spring-shaped wire core allows the heat to be more evenly distributed throughout the coil, thus ensuring uniform heating. The user can adjust the heating power through the controller to meet the cooking needs of different dishes.

[0051] Combination Figure 8 In another embodiment, the coil 1 is an arc-shaped coil, and the furnace body 3 is an arc-shaped furnace body.
