Abstract
Description
Technical Field
[0001] This application relates to the field of household appliance technology, and more particularly to a coil and a stove. Background Technology
[0002] An induction cooker is a common cooking appliance with advantages such as high heating efficiency, fast heating speed, and safe use of electric heating.
[0003] Conventional induction cookers utilize the principle of electromagnetic induction eddy current heating. An alternating magnetic field is generated through a coil. When a pot made of magnetic material is placed on the cooktop, the alternating magnetic field cuts through the pot, thereby generating an alternating current (i.e., eddy current) at the bottom of the pot, causing the pot to heat up and thus heating the food.
[0004] However, conventional induction cookers can only heat cookware made of magnetic materials; they cannot heat cookware made of other materials, such as ceramic pots and earthenware pots. Utility Model Content
[0005] In view of the above problems, this application provides a coil and a stove that enables heating of cookware made of magnetic materials and other materials, thereby improving the versatility of the stove.
[0006] In a first aspect, this application provides a coil disk, the coil disk comprising: a coil disk support, the coil disk support including an annular winding region; an electromagnetic coil disposed in the winding region; and a magnetic sensing element disposed on the inner side of the electromagnetic coil along the radial direction of the coil disk support.
[0007] The coil of this application, when the cookware to be heated is non-magnetic, will generate a large amount of heat under the magnetic field of the electromagnetic coil, and will heat the cookware of various materials through thermal radiation or thermal conduction. When the cookware to be heated is magnetic, the electromagnetic coil can directly act on the cookware, heating it through electromagnetic induction. At the same time, a portion of the magnetic field also acts on the magnetic element, indirectly heating the cookware through the heat generated by the magnetic element. Thus, the coil can heat both magnetic and non-magnetic cookware, possessing the ability to heat any type of cookware and a wider range of stovetop applications.
[0008] In some embodiments, the coil support forms a through hole; the magnetic sensing element is disposed inside the through hole.
[0009] In this way, the through-hole can be used to provide space for installing magnetic sensing components, thereby improving space utilization.
[0010] Furthermore, the through hole can also serve as a weight-reduction hole, which helps to reduce the weight of the coil support, thereby achieving a lightweight design of the stove, which helps to reduce costs and facilitates handling.
[0011] In some embodiments, the coil support includes: a first support ring, a coil mounting portion, and a second support ring that are sequentially distributed and connected from the inside to the outside along the radial direction of the coil support, the through hole being located radially inside the first support ring; and the electromagnetic coil being disposed on the coil mounting portion.
[0012] In this way, the magnetic sensing element can be placed inside the electromagnetic coil. Moreover, by setting the first support ring and the second support ring, the coil mounting part and the heat insulation element can be supported at a certain height, which facilitates ventilation and heat dissipation for the electromagnetic coil and the magnetic sensing element.
[0013] In some embodiments, there are multiple coil mounting portions, which are distributed at circumferential intervals along the coil disk support.
[0014] By setting multiple coil mounting parts distributed circumferentially along the coil disk support, the multiple coil mounting parts can evenly support the electromagnetic coil, and can further reduce the weight of the coil disk support. In addition, the gaps between the coil mounting parts are conducive to airflow, thereby improving the heat dissipation efficiency of the coil disk.
[0015] In some embodiments, along the axial direction of the coil disk support, a plurality of partition ribs are provided on one side surface of the coil mounting portion, the plurality of partition ribs are distributed radially at intervals along the coil disk support, and a wire groove is defined between two adjacent partition ribs, and the electromagnetic coil is wound in the wire groove.
[0016] Through the design of the ribs and grooves, the electromagnetic coil can be wound orderly on the coil plate support, avoiding problems such as loosening or deformation of the electromagnetic coil, thereby improving heating power and stability. In addition, the rib design enhances the structural strength of the coil plate support, enabling it to withstand greater loads and more complex working environments. The ribs and grooves also help optimize the magnetic field distribution, allowing the magnetic field generated by the electromagnetic coil to act more evenly on the sensing element and the cookware, thus achieving a more uniform heating effect.
[0017] In some embodiments, the coil disk further includes: a heat insulation member disposed on the coil disk support, the magnetic sensing member disposed on the heat insulation member, and the heat insulation member being used to insulate the magnetic sensing member and the electromagnetic coil from heat.
[0018] By incorporating heat insulation components, the high temperatures generated by the magnetic induction component during heating are effectively isolated, preventing heat from being directly transferred to the electromagnetic coil. This protects the electromagnetic coil from high-temperature damage and extends its service life. Furthermore, the heat insulation components also support the magnetic induction component. Through a stable support structure, the component is ensured to maintain its correct position within the mounting slot, preventing displacement or deformation during heating, thereby preserving the overall performance and stability of the coil.
[0019] In some embodiments, the heat insulation member includes: a pad body abutting against the coil support; a boss disposed on the side surface of the pad body facing away from the coil support, the boss being annular in shape extending circumferentially along the pad body, and the magnetic sensing element being disposed radially inside the boss.
[0020] Thus, by placing the heat insulation component on the coil support opposite the through hole, it can be positioned close to the central area of the coil support. This allows the magnetic sensing element to be placed in the central area of the coil support, with the electromagnetic coil arranged outside the magnetic sensing element. The heat insulation component effectively isolates the high temperature generated by the magnetic sensing element during heating, preventing heat from being directly transferred to the electromagnetic coil, thereby protecting the electromagnetic coil from high-temperature damage and extending its service life. Furthermore, the heat insulation component has a relatively simple structure and is easy to manufacture.
[0021] In some embodiments, the height of the boss is greater than the height of the magnetic sensing element.
[0022] Thus, on the one hand, the boss can prevent the heat generated by the magnetic sensing element from spreading radially along the coil support, thereby avoiding heat transfer to the electromagnetic coil and affecting its normal operation; on the other hand, the boss can guide the heat generated by the magnetic sensing element to radiate or conduct towards the cookware side, ensuring that most of the heat can be applied to the cookware, reducing heat loss and improving the heating efficiency of the cookware.
[0023] In some embodiments, the coil disk further includes a magnetic element disposed on the side of the coil disk support opposite to the electromagnetic coil.
[0024] By placing the magnetic component on the side of the coil support facing away from the electromagnetic coil, the magnetic field can be effectively guided towards the cookware and the magnetic sensing component, reducing the magnetic field lines of the electromagnetic coil from radiating away from the cookware, thereby reducing energy loss and improving the heating efficiency of the cookware and the magnetic sensing component.
[0025] Secondly, this application also provides a stove, including a housing defining a receiving cavity; and the aforementioned coil, the coil being disposed within the receiving cavity.
[0026] The stove of this application, by incorporating the aforementioned coil, achieves compatibility with various pots and pans, thus improving the stove's versatility. Attached Figure Description

[0044] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0045] An induction cooker is a common cooking appliance with advantages such as high heating efficiency, fast heating speed, and safe use of electric heating.
[0046] Conventional induction cookers utilize the principle of electromagnetic induction eddy current heating. An alternating magnetic field is generated by an electromagnetic coil on the coil plate. When a pot made of magnetic material is placed on the cooktop, the alternating magnetic field cuts through the pot, thereby generating an alternating current (i.e., eddy current) at the bottom of the pot, causing the pot to heat up on its own to heat the food.
[0047] However, conventional induction cookers can only heat cookware made of magnetic materials; they cannot heat cookware made of other materials, such as ceramic pots and earthenware pots.
[0048] In view of this, this application provides a coil and a stove. When the cookware to be heated is non-magnetic, the magnetic induction element will generate a large amount of heat under the magnetic field of the electromagnetic coil, and the magnetic induction element will heat the cookware of various materials by means of thermal radiation or thermal conduction. When the cookware to be heated is magnetic, the electromagnetic coil can directly act on the cookware to heat it through electromagnetic induction. At the same time, a part of the magnetic field also acts on the magnetic induction element, indirectly heating the cookware by the heat generated by the magnetic induction element. Thus, the coil of this embodiment can heat both magnetic and non-magnetic cookware, possessing the ability to heat any type of cookware and having a wider range of applications.
[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0050] The following will combine Figures 1 to 4 The coil disk 10 of the present application embodiment will be described.
[0051] Reference Figure 1 and Figure 2 As shown, the coil 10 in this embodiment is used to heat the cookware 2. Optionally, the cookware 2 can be a magnetic cookware 2 or a non-magnetic cookware 2.
[0052] refer to Figure 3 and Figure 4The coil disk 10 includes a coil disk support 100, an electromagnetic coil 200, and a magnetic sensing element 300. The coil disk support 100 includes a ring-shaped winding area. For example, the coil disk support 100 can be entirely ring-shaped, such as a circular ring, in which case the entire coil disk support 100 can serve as the winding area; alternatively, a portion of the coil disk support 100 can be ring-shaped and serve as the winding area. The coil disk support 100 provides a stable support structure and serves as the carrier for the electromagnetic coil 200, the heat insulation element 400, and the magnetic sensing element 300, ensuring overall stability and durability.
[0053] The electromagnetic coil 200 can be placed in the winding area of the coil support 100. When the electromagnetic coil 200 is energized, it will generate an alternating magnetic field. The cookware 2 can cut the magnetic field lines, thereby generating an eddy current effect and heating the cookware 2.
[0054] The magnetic sensing element 300 can be disposed on the inner side of the electromagnetic coil 200 along the radial direction of the coil support 100. The magnetic sensing element 300 can be formed in the shape of a sheet, and its thickness can be reasonably selected as needed. The magnetic sensing element 300 is suitable for generating heat under the action of the magnetic field lines of the electromagnetic coil 200 to heat the cookware 2. It can be understood that the magnetic sensing element 300 can also cut the magnetic field lines of the alternating magnetic field generated by the electromagnetic coil 200, thereby achieving heating. As heat accumulates, the magnetic sensing element 300 heats up and transfers the heat to the cookware 2 through heat conduction.
[0055] Optionally, the magnetic sensing element 300 may be made of a material with high magnetic permeability, such as ferrite or silicon steel sheet, so as to generate heat efficiently under the action of the magnetic field generated by the electromagnetic coil 200.
[0056] It should be noted that when the cookware 2 to be heated is a magnetic cookware 2 such as an iron cookware 2, most of the magnetic field energy generated by the electromagnetic coil 200 can directly act on the cookware 2, causing the cookware 2 to cut the magnetic field lines and thus heat the cookware 2; a small portion of the magnetic field energy can heat the magnetic sensing element 300, and then the magnetic sensing element 300 will conduct the heat to the cookware 2 through thermal radiation, thus realizing a dual heating method of electromagnetic heating and thermal radiation heating.
[0057] When the cookware 2 to be heated is a non-magnetic cookware 2, most of the magnetic field energy generated by the electromagnetic coil 200 acts on the magnetic sensing element 300. After the magnetic sensing element 300 heats up, it conducts the heat to the cookware 2 through thermal radiation, thereby heating the non-magnetic cookware 2.
[0058] Furthermore, since the electromagnetic coil 200 is located on the outside of the magnetic sensing element 300, for a cookware 2 with a radial dimension similar to that of the electromagnetic coil 200, the electromagnetic coil 200 can heat both the bottom and the side of the cookware 2, which helps to ensure the uniformity of heating of the cookware 2 and thus improve the uniformity of the internal temperature of the cookware 2.
[0059] In this embodiment of the coil 10, when the cookware 2 to be heated is non-magnetic, the magnetic induction element 300 generates a large amount of heat under the magnetic field of the electromagnetic coil 200, and the magnetic induction element 300 heats the cookware 2 of various materials through thermal radiation or thermal conduction. When the cookware 2 to be heated is magnetic, the electromagnetic coil 200 can directly act on the cookware 2, heating it through electromagnetic induction. At the same time, a portion of the magnetic field also acts on the magnetic induction element 300, indirectly heating the cookware 2 through the heat generated by the magnetic induction element 300. Thus, the coil 10 of this embodiment can heat both magnetic and non-magnetic cookware, possessing the ability to handle various cookware types and a wider range of applications. Furthermore, the heat insulation element 400 can prevent the heat generated by the magnetic induction element 300 from being transferred to the electromagnetic coil 200, ensuring the normal operation of the electromagnetic coil 200 and improving the stability and reliability of the coil 10.
[0060] Optionally, the coil disk 10 may further include a heat insulation component 400. The heat insulation component 400 is disposed on the coil disk support 100, and the magnetic sensing component 300 is fixedly disposed on the heat insulation component 400. The heat insulation component 400 is used to insulate the magnetic sensing component 300 and the electromagnetic coil 200 from heat. In this way, by setting the heat insulation component 400, it can effectively isolate the high temperature generated by the magnetic sensing component 300 during the heating process, preventing heat from being directly transferred to the electromagnetic coil 200, thereby protecting the electromagnetic coil 200 from high temperature damage and extending its service life. In addition, the heat insulation component 400 also plays a role in supporting the magnetic sensing component 300. Through a stable support structure, it ensures that the magnetic sensing component 300 maintains the correct position in the mounting groove, preventing it from shifting or deforming during the heating process, thereby maintaining the overall performance and stability of the coil disk 10.
[0061] In some embodiments, reference Figure 3 and Figure 4 The coil support 100 has a through hole 170, which is located in the middle of the coil support 100 and extends through the coil support 100 along its axial direction. The heat insulation member 400 is supported on one side of the coil support 100 along its thickness direction and covers the through hole 170.
[0062] In this way, the through hole 170 provides space for the magnetic sensing element, improving space utilization. Furthermore, the heat insulation element 400 is positioned on the coil support 100 opposite to the through hole 170, allowing it to be placed close to the central area of the coil support 100. This facilitates the placement of the magnetic sensing element 300 in the central area of the coil support 100, with the electromagnetic coil 200 arranged outside the magnetic sensing element 300. Additionally, the through hole 170 can also serve as a weight-reduction hole, helping to reduce the weight of the coil support 100, thereby achieving a lightweight design for the stove 1, reducing costs, and facilitating handling.
[0063] In some embodiments, reference Figure 3 and Figure 4 The coil support 100 may include a first support ring 130, a coil mounting portion 110, and a second support ring 140. The first support ring 130, the coil mounting portion 110, and the second support ring 140 may be sequentially distributed and connected from the inside to the outside along the radial direction of the coil support 100. The first support ring 130 and the second support ring 140 may be formed as concentric circles, and the through hole 170 is located radially inside the first support ring 130. The coil mounting portion 110 constitutes the aforementioned winding area.
[0064] Along the axial direction of the coil mounting portion 110, the thickness of the coil mounting portion 110 can be less than the height of either the first support ring 130 or the second support ring 140. The coil mounting portion 110 can be a plate-like structure. The electromagnetic coil 200 is disposed in the coil mounting portion 110, and the heat insulation member 400 is supported on the first support ring 130.
[0065] In this way, the magnetic sensing element 300 can be placed inside the electromagnetic coil 200. Moreover, by setting the first support ring 130 and the second support ring 140, the coil mounting part 110 and the heat insulation element 400 can be supported at a certain height, which facilitates ventilation and heat dissipation for the electromagnetic coil 200 and the magnetic sensing element 300.
[0066] Optionally, the coil mounting portion 110 can be formed as an annular shape extending circumferentially along the coil disk support 100; or, the coil mounting portion 110 can be formed as an arcuate segment extending circumferentially along the coil disk support 100. The coil mounting portion 110 can be formed as a continuous surface or can be provided with a hollow structure. The side surface of the coil mounting portion 110 for mounting the electromagnetic coil 200 can be a flat surface or a curved surface. Of course, this application is not limited to this, and the structure of the coil mounting portion 110 can be reasonably selected according to actual needs.
[0067] Optionally, the heat insulation component 400 can be detachably connected to the first support ring 130. For example, the first support ring 130 may have a hook, and the heat insulation component 400 may have a latch, allowing the hook to engage with the heat insulation component 400. Alternatively, the heat insulation component 400 may have a first connecting hole, and the first support ring 130 may have a second connecting hole, with the heat insulation component 400 and the first support ring 130 connected by fasteners passing through the first and second connecting holes. Alternatively, the heat insulation component 400 and the first support ring 130 may be bonded together. Of course, this application is not limited to these methods; the connection method between the heat insulation component 400 and the coil support 100 can be reasonably selected as needed.
[0068] This ensures the stable installation of the heat insulation component 400 on the coil support 100, thereby providing a stable installation environment for the magnetic sensing component 300.
[0069] In some embodiments, reference Figure 3 and Figure 4 There can be multiple coil mounting portions 110, which are distributed at intervals along the circumference of the coil disk support 100. Optionally, the arc length of each coil mounting portion 110 along the circumference of the coil disk support 100 can be equal or unequal, and the length of each coil mounting portion 110 along the circumference of the coil disk support 100 can be flexibly selected according to actual needs.
[0070] By setting multiple coil mounting portions 110 distributed circumferentially along the coil disk support 100, the multiple coil mounting portions 110 can uniformly support the electromagnetic coil 200, and can further reduce the weight of the coil disk support 100. In addition, the gap between the coil mounting portions 110 is conducive to airflow, thereby improving the heat dissipation efficiency of the coil disk 10.
[0071] In some embodiments, reference Figure 3 and Figure 4 Along the axial direction of the coil disk support 100, a plurality of partition ribs 150 are provided on one side surface of the coil mounting part 110 (i.e., the upper surface of the coil mounting part 110). The plurality of partition ribs 150 can be distributed radially at intervals along the coil disk support 100, and a wire groove 160 is defined between two adjacent partition ribs 150. The electromagnetic coil 200 can be wound in the wire groove 160.
[0072] Through the design of the baffle 150 and the wire groove 160, the electromagnetic coil can be wound orderly on the coil plate support 100, avoiding the problem of loosening or deformation of the electromagnetic coil, thereby improving heating power and stability. In addition, the design of the baffle 150 enhances the structural strength of the coil plate support 100, enabling it to withstand greater loads and more complex working environments. The design of the baffle 150 and the wire groove 160 also helps to optimize the magnetic field distribution, so that the magnetic field generated by the electromagnetic coil acts more evenly on the magnetic sensing element 300 and the pot 2, thereby achieving a more uniform heating effect.
[0073] In some embodiments, reference Figure 3 and Figure 4 Along the axial direction of the coil support 100, the magnetic sensing element 300 is higher than the surface of the coil mounting portion 110 facing the cookware 2, and lower than the surface of the electromagnetic coil 200 facing away from the coil mounting portion 110. In other words, the magnetic sensing element 300 is higher than the upper surface of the coil mounting portion 110 and lower than the upper surface of the electromagnetic coil 200.
[0074] This configuration ensures that the magnetic sensing element 300 and the electromagnetic coil 200 are radially opposite each other along the coil support 100. This allows more magnetic field lines generated by the electromagnetic coil 200 to pass through the magnetic sensing element 300, enabling more magnetic field energy to act on the magnetic sensing element 300, reducing magnetic field energy loss, and improving the heating efficiency of the magnetic sensing element 300.
[0075] In some embodiments, reference Figure 3 and Figure 4 The surface of the coil mounting portion 110 facing the cookware 2 is flush with the surfaces of the first support ring 130 and the second support ring 140 facing the cookware 2. In other words, the upper surface of the coil mounting portion 110 is flush with the upper surfaces of the first support ring 130 and the second support ring 140.
[0076] Since the heat insulation element 400 is located on the side surface of the first support ring 130 facing the cookware 2, this arrangement allows the electromagnetic coil 200 and the heat insulation element 400 to be arranged radially opposite each other along the coil support 100, so that the heat insulation element 400 can better prevent the heat of the magnetic sensing element 300 from being transferred to the electromagnetic coil 200.
[0077] In addition, since the partition 150 is located on the side of the coil mounting part 110 facing the cookware 2, the partition 150 can be arranged around the heat insulation pad. In this way, the partition 150 can play a role in fixing the heat insulation pad, further improving the installation stability of the heat insulation pad and the magnetic sensing element 300.
[0078] In some embodiments, reference Figure 3 and Figure 4 The heat insulation component 400 may include a pad body 411 and a boss 412. The pad body 411 may be formed in a disc shape, and may have a continuous surface or a perforated structure. The surface of the pad body 411 facing the cookware 2 may be flat or curved. However, this application is not limited to these limitations; the structure of the pad body 411 can be reasonably selected according to actual needs. The pad body 411 abuts against the coil support 100. For example, the pad body 411 may be located on the surface of the coil support 100 facing the cookware 2 (e.g., the pad body 411 may be located on the first support ring 130) and cover the through hole 170.
[0079] The boss 412 can be provided on the side surface of the pad body 411 facing the cookware 2. The boss 412 is in the shape of a ring extending circumferentially along the pad body 411. The magnetic sensing element 300 is provided on the radial inner side of the boss 412. The magnetic sensing element 300 can be fixed to the pad body 411 or the boss 412.
[0080] Thus, the heat insulation component 400 can effectively isolate the high temperature generated by the magnetic sensing component 300 during the heating process, preventing heat from being directly transferred to the electromagnetic coil 200, thereby protecting the electromagnetic coil 200 from high-temperature damage and extending its service life. Furthermore, the heat insulation component 400 has a relatively simple structure and is easy to manufacture.
[0081] Optionally, the heat insulation component 400 can be made of plastic or other materials with low thermal conductivity to ensure that the heat insulation component 400 has good heat insulation properties.
[0082] In some embodiments, reference Figure 3 and Figure 4 The height of the boss 412 is higher than the height of the magnetic sensing element 300.
[0083] Thus, on the one hand, the boss 412 can prevent the heat generated by the magnetic sensing element 300 from spreading radially along the coil support 100, thereby avoiding the heat transfer to the electromagnetic coil 200 and affecting the normal operation of the electromagnetic coil 200; on the other hand, the boss 412 can guide the heat generated by the magnetic sensing element 300 to radiate or conduct towards the cookware 2 side, so as to ensure that most of the heat can be applied to the cookware 2, reduce heat loss, and improve the heating efficiency of the cookware 2.
[0084] In some embodiments, reference Figure 3 and Figure 4 The coil disk 10 also includes a magnetic element 500, which can be a magnet. The magnetic element 500 is located on the side of the coil disk support 100 opposite to the electromagnetic coil 200 (i.e., the lower side of the coil disk support 100).
[0085] By placing the magnetic element 500 on the side of the coil support 100 facing away from the electromagnetic coil 200, the magnetic field direction can be effectively guided towards the cookware 2 and the magnetic sensing element 300, reducing the magnetic field lines of the electromagnetic coil 200 radiating away from the cookware 2, thereby reducing energy loss and improving the heating efficiency of the cookware 2 and the magnetic sensing element 300.
[0086] In some embodiments, reference Figure 3 and Figure 4 The magnetic component 500 can be multiple, corresponding to the coil mounting portion 110. The coil mounting portion 110, together with the first support ring 130 and the second support ring 140, defines a fixing groove facing away from the opening of the electromagnetic coil 200. The magnetic component 500 is disposed in the fixing groove.
[0087] Thus, the installation method of magnetic component 500 is relatively simple, making it easy to manufacture and assemble.
[0088] In some embodiments, the magnetic sensing element 300 includes an iron-chromium-aluminum alloy element or a nickel-chromium alloy element.
[0089] Iron-chromium-aluminum alloys possess high magnetic permeability and good heat resistance, while nickel-chromium alloys exhibit good resistivity, corrosion resistance, and high-temperature stability. This material selection ensures that the coil 10 can efficiently heat different types of cookware 2, while also maintaining uniform heat distribution and enhancing the compatibility of the cookware 2.
[0090] In some embodiments, reference Figure 3 and Figure 4 The electromagnetic coil 200 may include multiple coils formed by winding, with the multiple coils nested inside and outside the coil disc support 100 along its radial direction. This generates a more uniform and powerful magnetic field, thereby increasing the heating power.
[0091] It is understandable that each turn of the electromagnetic coil 200 around the central axis of the coil support 100 forms a layer, and adjacent layers are connected and distributed radially along the coil support 100, thus giving the electromagnetic coil 200 multiple layers. This multi-layered design allows the electromagnetic coil 200 to generate a stronger and more uniform magnetic field, thereby increasing heating power and enabling the coil 10 to heat the pot 2 more quickly, reducing waiting time.
[0092] The following is for reference. Figure 1 and Figure 2 The stove 1 is described according to a second aspect embodiment of this application.
[0093] The stove 1 in this embodiment includes, but is not limited to, an induction cooker. The stove 1 in this embodiment may include a housing 20 and a coil 10 as described in the above embodiment.
[0094] like Figure 2 As shown, the outer shell 20 defines a receiving cavity. Specifically, the outer shell 20 may include a shell body 21 and a panel 22. The shell body 21 defines the receiving cavity, which has an opening on one side along the height direction of the outer shell 20. The panel 22 covers the opening. The panel 22 may be a liquid crystal panel 22, a ceramic plate, or a panel 22 made of other materials. The panel 22 may serve as a carrier for the cookware 2 and is used to place the cookware 2.
[0095] The coil 10 can be disposed in the receiving cavity, and the coil 10 can be arranged opposite to the opening and the panel 22 to facilitate heating the pot 2.
[0096] By incorporating the aforementioned coil 10 into the stove 1, the stove 1 achieves compatibility with various pots and pans, thus improving its versatility.
[0097] In some embodiments, the stove 1 may further include a control system, which may include a circuit board 30 and is electrically connected to the electromagnetic coil 200. It is understood that the stove 1 provided in this application embodiment, compared to conventional technologies where electromagnetic heating and heat conduction require two separate systems to control electromagnetic and heat conduction independently, uses only one control system to achieve both electromagnetic and heat conduction heating methods. This simplifies control, reduces the number of components inside the stove 1, and lowers production costs.
[0098] Optional, such as Figure 2 As shown, the stove 1 may also include a heat dissipation device, which may be a fan 40. The heat dissipation device is located inside the housing cavity. The outer shell 20 may have an air inlet and an air outlet. The heat dissipation device is used to drive airflow into the housing cavity from the air inlet and out of the housing cavity from the air outlet. When the airflow flows through the coil 10, it can carry away the heat of the coil 10, ensuring the stable and reliable operation of the coil 10.
[0099] Optionally, such as Figure 2 As shown, in order to facilitate the installation of components such as coil 10, fan 40, and circuit board 30 in the receiving cavity, the housing body 21 may include a bottom shell 211 and a top cover 212. An opening is formed in the top cover 212. The bottom shell 211 and the top cover 212 are detachably connected and together define the receiving cavity.
