Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The following is for reference. Figures 1-4 The cooking device 100 according to the present invention describes a cooking device 100 in which a heating coil 2 can be installed by setting a device body 1, and a cooking space 11 is formed inside the device body 1 to accommodate objects, so that the heating coil 2 can heat the objects in the cooking space 11, thereby realizing the cooking function of the cooking device 100. At the same time, by setting at least two heating structures 26 on the heating coil 2, the at least two heating structures 26 can heat different areas in the cooking space 11 respectively, thereby improving the heating efficiency and reliability.

[0032] like Figure 1 As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1 and a heating coil plate 2.

[0033] The main body of the device 1 has a cooking space 11; the heating coil 2 is distributed along a first direction with the cooking space 11, and the heating coil 2 includes at least two heating structures 26 distributed along a second direction. The at least two heating structures 26 are used to heat at least two areas of the cooking space 11 respectively, and the second direction intersects with the first direction.

[0034] Specifically, the main body 1 serves as the skeleton of the cooking equipment 100, providing installation space for components within the cooking equipment 100. A cooking space 11 is formed within the main body 1, which can accommodate objects for heating. A heating coil 2 generates heat to heat the objects within the cooking space 11. The heating coil 2 is mounted on the main body 1 for reliable operation. Distributing the heating coil 2 and the cooking space 11 along a first direction separates them, preventing the heating coil 2 from occupying internal space and reducing its volume. It also prevents objects from affecting the heating coil 2 and causing it to malfunction, thus ensuring both the proper volume of the cooking space 11 and the reliable operation of the heating coil 2. The objects to be heated can be food ingredients or cooking utensils 28, etc.

[0035] Meanwhile, the heating coil 2 includes a heating structure 26, which generates heat to achieve the heating function of the heating coil 2. At least two heating structures 26 are provided in the heating coil 2, that is, the number of heating structures 26 can be two, three or more, so that the object can be heated simultaneously by at least two heating structures 26, which can improve the heating efficiency of the object. Moreover, by distributing at least two heating structures 26 along the second direction, the at least two heating structures 26 can be spaced apart along the second direction to avoid interference between the at least two heating structures 26, which would cause uneven heat generation or failure to generate heat, thereby improving the reliability of the operation of the heating structure 26, and thus improving the reliability of the operation of the heating coil 2.

[0036] Furthermore, at least two heating structures 26 are used to heat at least two areas within the cooking space 11 respectively. By distributing at least two heating structures 26 at intervals, at least two heating structures 26 can heat different areas within the cooking space 11 respectively, thereby improving the efficiency and reliability of heating objects.

[0037] It should be noted that, in actual use, at least two heating structures 26 can be used to heat a single object or multiple objects within the cooking space 11. When heating a single object, the heights of the at least two heating structures 26 can be configured to be different, so that different areas of the single object can be heated simultaneously by the at least two heating structures 26, thereby reducing the temperature difference between different areas and improving the uniformity and efficiency of heating. When heating multiple objects, the at least two heating structures 26 can be used to heat multiple objects simultaneously, which can improve the heating efficiency. For example, the cooking device 100 can be used to heat cooking pots 28. When heating a single pot, the bottom and side walls of the cooking pot 28 can be heated simultaneously, or the cooking device 100 can be used to heat multiple cooking pots 28 simultaneously.

[0038] Furthermore, the second direction intersects with the first direction, and one of the first and second directions can be a horizontal direction and the other can be a vertical direction.

[0039] According to the embodiment of the present invention, the cooking device 100 can install the heating coil 2 by setting the device body 1, and form a cooking space 11 inside the device body 1 to accommodate objects, so that the heating coil 2 can heat the objects in the cooking space 11, thereby realizing the cooking function of the cooking device 100. At the same time, by setting at least two heating structures 26 on the heating coil 2, the at least two heating structures 26 can heat different areas in the cooking space 11 respectively, thereby improving the heating efficiency and reliability.

[0040] In some embodiments, the heating coil 2 includes: a main support 21, a first winding 22, a first magnetic core 23, a second winding 24, and a second magnetic core 25. The first winding 22 and the first magnetic core 23 are distributed opposite to each other on the main support 21 along a first direction. The second winding 24 and the second magnetic core 25 are distributed opposite to each other on the main support 21 along the first direction. The second winding 24 and the first winding 22 are distributed along a second direction. The first winding 22 and the second winding 24 are used to heat two areas of the cooking space 11 respectively.

[0041] Specifically, the main support 21 can serve as a skeleton, providing mounting positions for the first winding 22, the first magnetic core 23, the second winding 24, and the second magnetic core 25. All three components can be mounted on the main support 21 for fixation, preventing displacement and potential failure. The first winding 22 and the second winding 24 are used to heat the object. By distributing the first winding 22 and the first magnetic core 23 relative to each other in the first direction, and the second winding 24 and the second magnetic core 25 relative to each other in the first direction, the first magnetic core 23 and the second magnetic core 25 can be used to strengthen the magnetic field, change the distribution of magnetic lines of force, and prevent magnetic leakage. This allows more energy to be concentrated on the side containing the first winding 22 and the second winding 24, improving the heating efficiency of the first winding 22 and the second winding 24.

[0042] Furthermore, by distributing the second winding 24 and the first winding 22 along the second direction, the first winding 22 and the second winding 24 can be spaced apart along the second direction to avoid interference between them, which would prevent the first winding 22 and the second winding 24 from generating heat. This ensures the reliable operation of the first winding 22 and the second winding 24. Moreover, the first winding 22 and the second winding 24 are used to heat two areas of the cooking space 11 respectively, which means that the first winding 22 and the second winding 24 can simultaneously heat two areas of the cooking space 11, thereby improving the heating efficiency and reliability.

[0043] It should be noted that, for example Figures 1-4 As shown, two heating structures 26 can be set on the heating coil disk 2, such that one heating structure 26 includes a first winding 22 and a first magnetic core 23, and the other heating structure 26 includes a second winding 24 and a second magnetic core 25. The heating function of the two heating structures 26 can be realized through the first winding 22 and the second winding 24, that is, the function of heating coil disk 2 to heat different areas can be realized.

[0044] In such Figure 2-Figure 4 In the illustrated embodiment, the first winding 22 and the first magnetic core 23 are distributed in a vertical direction, and the second winding 24 and the second magnetic core 25 are also distributed in a vertical direction. This allows the first winding 22 and the second winding 24 to heat the object in a vertical direction, i.e., the first direction is vertical. Moreover, the first winding 22 is located above the first magnetic core 23, and the second winding 24 is located below the second magnetic core 25. This allows the first winding 22 to heat the object located above the heating coil 2, and the second winding 24 to heat the object located below the heating coil 2, thus achieving bidirectional heating of the heating coil 2.

[0045] In some embodiments, the second direction is along the radial direction of the second winding 24, which is distributed around the first winding 22.

[0046] Specifically, the first winding 22 and the second winding 24 are distributed along a second direction, and the second direction is radially along the second winding 24. This allows the first winding 22 and the second winding 24 to be distributed radially along the second winding 24. Consequently, the first winding 22 can be positioned either outside or inside the second winding 24, thus achieving the desired arrangement. This also reduces the space occupied by the heating coil 2 in the first direction, facilitating the arrangement of the heating coil 2 and reducing the size of the cooking setup, making the cooking device 100 more portable. Furthermore, as... Figure 2-Figure 4 As shown, by setting the second winding 24 around the first winding 22, the second winding 24 can be set outside the first winding 22, which can realize the setting of the first winding 22 and the second winding 24, and can reduce the space occupied by the heating coil 2 in the height direction, which is beneficial to the setting of the heating coil 2.

[0047] In some embodiments, the main support 21 has a first side and a second side that are distributed opposite to each other along a first direction.

[0048] Specifically, the first direction is the vertical direction, that is, the first side can be above or below the main support 21, and the second side can be below or above the main support 21.

[0049] The main body bracket 21 has a first winding groove 214 for mounting the first winding 22 and a second core slot 215 for mounting the second core 25 on the first side. The main body bracket 21 has a second winding groove 216 for mounting the second winding 24 and a first core slot 217 for mounting the first core 23 on the second side.

[0050] Specifically, the first winding slot 214 is used to install the first winding 22, to arrange and fix the first winding 22 to prevent it from tangling or bending and thus failing; the second magnetic core slot 215 is used to install the second magnetic core 25, to install and fix the second magnetic core 25 to prevent it from moving and thus failing; the second winding slot 216 is used to install the second winding 24, to arrange and fix the second winding 24 to prevent it from tangling or bending and thus failing; and the first magnetic core slot 217 is used to install the first magnetic core 23, to install and fix the first magnetic core 23 to prevent it from moving and thus failing.

[0051] Furthermore, the first winding groove 214 and the second magnetic core slot 215 are disposed on the first side of the main body support 21, and the second winding groove 216 and the first magnetic core slot 217 are disposed on the second side of the main body support 21. The first winding 22 can be used to heat the object located on the first side of the main body support 21, and the second winding 24 can be used to heat the object located on the second side of the main body support 21. Moreover, the first magnetic core 23 can be used to concentrate more energy on the side where the first winding 22 is located, that is, on the first side of the main body support 21, thereby improving the heating efficiency of the first winding 22. The second magnetic core 25 can be used to concentrate more energy on the side where the second winding 24 is located, that is, on the second side of the main body support 21, thereby improving the heating efficiency of the second winding 24.

[0052] For example, such as Figure 2-Figure 4 As shown, the first winding groove 214 and the second magnetic core slot 215 are disposed above the main body support 21, and the second winding groove 216 and the first magnetic core slot 217 are disposed below the main body support 21. That is, the first side of the main body support 21 is the upper side of the main body support 21, and the second side is the lower side of the main body support 21.

[0053] In some embodiments, the main support 21 is constructed in an annular shape, and the main support 21 includes a first ring portion 211, a second ring portion 212 and a third ring portion 213 distributed radially from the inside to the outside, a first winding groove 214 is formed between the first ring portion 211 and the second ring portion 212, and a second winding groove 216 is formed between the second ring portion 212 and the third ring portion 213.

[0054] Specifically, the first ring portion 211, the second ring portion 212, and the third ring portion 213 are arranged sequentially from the inside to the outside along the radial direction of the main body support 21, thus separating the first ring portion 211, the second ring portion 212, and the third ring portion 213 along the radial direction of the main body support 21. The first winding groove 214 is set between the first ring portion 211 and the second ring portion 212, that is, the first winding 22 is set between the first ring portion 211 and the second ring portion 212, and the area between the first ring portion 211 and the second ring portion 212 is heated by the first winding 22. The second winding groove 216 is set between the second ring portion 212 and the third ring portion 213, that is, the second winding 24 is set between the second ring portion 212 and the third ring portion 213, and the area between the second ring portion 212 and the third ring portion 213 is heated by the second winding 24.

[0055] It should be noted that the main support 21 is constructed in a ring shape. The first winding groove 214 is disposed between the first ring portion 211 and the second ring portion 212, and the second winding groove 216 is disposed between the second ring portion 212 and the third ring portion 213. That is, both the first winding groove 214 and the second winding groove 216 are constructed in a ring shape, which facilitates the protection of the first winding 22 and the second winding 24 and prevents them from bending and breaking during the arrangement of the first winding 22 and the second winding 24.

[0056] In some embodiments, the first magnetic core slot 217 extends radially from the first ring portion 211 to the second ring portion 212 along the main body support 21, and the second magnetic core slot 215 extends radially from the second ring portion 212 to the third ring portion 213 along the main body support 21.

[0057] Specifically, the first magnetic core slot 217 is configured to extend radially from the first ring portion 211 to the second ring portion 212 along the main body support 21, that is, the first magnetic core 23 is placed on the first ring portion 211 and the second ring portion 212, and the first winding groove 214 is formed between the first ring portion 211 and the second ring portion 212, so that the first magnetic core 23 and the first winding 22 are directly opposite each other, so as to strengthen the electromagnetic field of the first winding 22 through the first magnetic core 23, so that more energy is concentrated above the first winding 22, thereby improving the heating efficiency of the first winding 22, and thus improving the efficiency of heating the object above the heating coil 2.

[0058] Meanwhile, the second magnetic core slot 215 is configured to extend radially from the second ring portion 212 to the third ring portion 213 along the main body support 21, that is, the second magnetic core 25 is placed on the second ring portion 212 and the third ring portion 213, and the second winding groove 216 is formed between the second ring portion 212 and the third ring portion 213. This allows the second magnetic core 25 and the second winding 24 to be arranged opposite each other, so as to strengthen the electromagnetic field of the second winding 24 through the second magnetic core 25, so that more energy is concentrated below the second winding 24, thereby improving the heating efficiency of the second winding 24, and thus improving the efficiency of heating the object below the heating coil 2.

[0059] In some embodiments, the first magnetic core 23 includes a first body segment 232, a first inner segment 231 and a first outer segment 233. The first inner segment 231 and the first outer segment 233 are respectively bent and connected to the two ends of the first body segment 232. The first inner segment 231 extends from the first ring portion 211 to the first side, and the first outer segment 233 extends from the second ring portion 212 to the first side.

[0060] Specifically, such as Figure 2-Figure 4As shown, the first inner segment 231 and the first outer segment 233 are respectively bent and connected to both ends of the first body segment 232, making the first magnetic core 23 shaped like a "Z". The first inner segment 231 extends from the first ring portion 211 to the first side, that is, the first inner segment 231 is disposed on the first ring portion 211 and extends from the lower surface to the upper surface of the first ring portion 211. A insertion hole 218 can be provided on the first ring portion 211 so that the first inner segment 231 can extend into the insertion hole 218 and cooperate with the insertion hole 218 to realize the first inner segment 231. The connection between segment 231 and the first ring portion 211 is such that the first outer segment 233 extends through the first side from the second ring portion 212, that is, the first outer segment 233 is disposed on the second ring portion 212 and extends from the lower surface to the upper surface of the second ring portion 212. A insertion hole 218 can be provided on the second ring portion 212 so that the first outer segment 233 can extend into the insertion hole 218 and cooperate with the insertion hole 218 to realize the connection between the first outer segment 233 and the second ring portion 212. Thus, the first magnetic core 23 can be mounted on the main body bracket 21.

[0061] And / or, the second magnetic core 25 includes a second body segment 252, a second inner segment 251 and a second outer segment 253, the second inner segment 251 and the second outer segment 253 are respectively bent and connected to the two ends of the second body segment 252, and the second inner segment 251 extends from the second ring portion 212 to the second side, and the second outer segment 253 extends from the third ring portion 213 to the second side.

[0062] Specifically, such as Figure 2-Figure 4 As shown, the second inner section 251 and the second outer section 253 are respectively bent and connected to both ends of the second body section 252, making the second magnetic core 25 shaped like a "Z". The second inner section 251 extends from the second ring portion 212 to the second side, meaning it is disposed on the second ring portion 212 and extends from the upper surface to the lower surface. A insertion hole 218 can be provided on the second ring portion 212 so that the second inner section 251 can extend into the insertion hole 218 and cooperate with it to realize the second inner... The second outer segment 253 extends through the third ring 213 from the second side of the second ring 213, that is, the second outer segment 253 is disposed on the third ring 213 and extends from the upper surface to the lower surface of the third ring 213. A insertion hole 218 can be provided on the third ring 213 so that the second outer segment 253 can extend into the insertion hole 218 and cooperate with the insertion hole 218 to realize the connection between the second outer segment 253 and the third ring 213. Thus, the second magnetic core 25 can be mounted on the main support 21.

[0063] It should be noted that the second ring portion 212 is connected to both the first outer segment 233 and the second inner segment 251. The insertion holes 218 on the second ring portion 212 that mate with the first outer segment 233 and the second inner segment 251 can be spaced apart to avoid interference between the first outer segment 233 and the second inner segment 251, thereby preventing interference between the first magnetic core 23 and the second magnetic core 25. Furthermore, multiple first magnetic cores 23 and second magnetic cores 25 are evenly spaced apart on the circumference of the main support 21 to uniformly enhance the magnetic field and effectively prevent magnetic leakage. For example... Figures 3-4 As shown, six first magnetic cores 23 and six second magnetic cores 25 are respectively provided in the heating coil disk 2. The number of first magnetic cores 23 and second magnetic cores 25 is not limited to that described in this embodiment, and can be flexibly set according to specific needs and space size.

[0064] In some embodiments, the first winding groove 214 is located between the first inner section 231 and the first outer section 233, and the second winding groove 216 is located between the second inner section 251 and the second outer section 253.

[0065] Specifically, the first winding groove 214 is disposed between the first inner section 231 and the first outer section 233, that is, the first winding 22 is disposed between the first inner section 231 and the first outer section 233. At the same time, the first magnetic core 23 extends from the first ring portion 211 to the second ring portion 212, so that the first magnetic core 23 and the first winding 22 are positioned opposite each other, so that the electromagnetic field of the first winding 22 can be enhanced by the first magnetic core 23, thereby improving the heating efficiency of the first winding 22.

[0066] Furthermore, the second winding groove 216 is disposed between the second inner section 251 and the second outer section 253, that is, the second winding 24 is disposed between the second inner section 251 and the second outer section 253. At the same time, the second magnetic core 25 extends from the second ring portion 212 to the third ring portion 213, so that the second magnetic core 25 and the second winding 24 are positioned facing each other, so that the electromagnetic field of the second winding 24 can be enhanced by the second magnetic core 25, thereby improving the heating efficiency of the second winding 24.

[0067] In some embodiments, a first wire-locking groove 2141 is formed in the first winding groove 214, and the first winding 22 passes through the first wire-locking groove 2141.

[0068] Specifically, the first wire slot 2141 is used to fix the first winding 22, such as... Figure 2-Figure 3As shown, the first wire-locking groove 2141 is disposed between the first ring portion 211 and the second ring portion 212, and is disposed along the circumference of the first ring portion 211. The first winding 22 can be wound around the first winding groove 214 one circle after another along the first wire-locking groove 2141 to realize the arrangement and fixation of the first winding 22. Furthermore, the first wire-locking groove 2141 is configured as multiple arc-shaped segments that extend upward from the lower surface of the first winding groove 214 and are evenly disposed around the first ring portion 211, which is beneficial for the arrangement of the first winding 22 and can reduce the use of materials and reduce the installation cost.

[0069] And / or, a second wire-locking groove 2161 is formed in the second winding groove 216, and the second winding 24 passes through the second wire-locking groove 2161.

[0070] Specifically, the second wire slot 2161 is used to fix the second winding 24, such as... Figure 2 and Figure 4 As shown, the second wire-locking groove 2161 is disposed between the second ring portion 212 and the third ring portion 213, and is disposed along the circumference of the second ring portion 212. The second winding 24 can be wound around the second winding groove 216 one circle at a time along the second wire-locking groove 2161 to achieve the arrangement and fixation of the second winding 24. Furthermore, the second wire-locking groove 2161 is configured as multiple arc-shaped segments that extend downward from the upper surface of the second winding groove 216 and are evenly disposed around the second ring portion 212, which is beneficial for the arrangement of the second winding 24 and can reduce the use of materials and reduce the installation cost.

[0071] It should also be noted that the first wire clamping groove 2141 and the second wire clamping groove 2161 may not be provided in the first winding groove 214 and the second winding groove 216. Instead, the first winding 22 and the second winding 24 may be coiled and arranged in the first winding groove 214 and the second winding groove 216 respectively. The first winding 22 and the second winding 24 may be used to heat objects located above and below the heating coil 2 respectively.

[0072] In some embodiments, the direction of rotation of the first winding 22 is opposite to that of the second winding 24.

[0073] Specifically, the first winding 22 is located above the main support 21, and the second winding 24 is located below the main support 21. By setting the rotation directions of the first winding 22 and the second winding 24 to opposite directions, the first winding 22 can be wound clockwise and the second winding 24 can be wound counterclockwise, or the first winding 22 can be wound counterclockwise and the second winding 24 can be wound clockwise. Both arrangements can achieve bidirectional heating of the heating coil 2 by using the first winding 22 and the second winding 24 to heat objects located in the upper and lower directions of the heating coil 2.

[0074] The rotation direction of the first winding 22 and the second winding 24 can be flexibly selected according to the specific circumstances during actual production.

[0075] It should also be noted that the height of the heating coil plate 2 in this application can be less than 9mm.

[0076] In some embodiments, the device body 1 has at least two cooking spaces 11, a heating coil 2 is located between two adjacent cooking spaces 11, and at least two heating structures 26 are used to heat at least two areas of the two adjacent cooking spaces 11.

[0077] Specifically, the cooking space 11 is used to accommodate objects so that the heating coil 2 can heat the objects. The main body of the device 1 has at least two cooking spaces 11, that is, the number of cooking spaces 11 can be two, three or more, so that objects can be accommodated simultaneously by at least two cooking spaces 11, which can improve the efficiency of heating objects. At the same time, by placing the heating coil 2 between two adjacent cooking spaces 11, objects in two adjacent cooking spaces 11 can be heated simultaneously by one heating coil 2, which can reduce the number of heating coils 2 and reduce the installation cost.

[0078] And, such as Figure 2-Figure 4 As shown, the heating coil 2 includes two heating structures 26. The two heating structures 26 are used to heat two areas of two adjacent cooking spaces 11. That is, the two heating structures 26 can simultaneously heat two areas in two adjacent cooking spaces 11 to improve the efficiency of heating the object.

[0079] In some embodiments, there are two cooking spaces 11 that are spaced apart in the vertical direction. The upper cooking space 11 is formed on the top side of the device body 1, and the lower cooking space 11 is formed inside the device body 1.

[0080] Specifically, by separating the two cooking spaces 11 vertically, the two cooking spaces 11 can be separated along the first direction to avoid interference between the two cooking spaces 11, thereby ensuring reliable heating of objects in the two cooking spaces 11. It also facilitates simultaneous heating of objects in the two cooking spaces 11 by the heating coil 2, thereby improving heating efficiency and reliability. Furthermore, by forming the upper cooking space 11 on the top side of the device body 1 and the lower cooking space 11 inside the device body 1, the heating coil 2 can be placed on the top of the device body 1, so that the heating coil 2 can be used to simultaneously heat objects in the two cooking spaces 11, thereby improving the efficiency of heating objects.

[0081] It should be noted that, for example Figure 1 As shown, the upper cooking space 11 can be used to accommodate the cooking pot 28. A microcrystalline panel 27 can be covered on the upper surface of the heating coil 2 to support the cooking pot 28 and protect the heating coil 2 from water ingress or other dangerous situations. The upper part of the cooking device 100 can be used as an induction cooker. The upper surface of the lower cooking space 11 can be made of materials with magnetic conductivity such as SUS430, SUS304, and low carbon steel to radiate heat into the interior of the lower cooking space 11 using the second winding 24.

[0082] It should also be noted that by placing the heating coil 2 between the two cooking spaces 11, the first winding 22 can be used to heat the bottom of the object in the upper cooking space 11, and the second winding 24 can be used as the top heat source of the cooking space 11 in the lower space. For example, the first winding 22 can be used to heat the bottom of a rice cooker, electric kettle, etc., and the second winding 24 can be used as the top heat source of an electric oven, air fryer, etc. In actual design, different combinations can be selected according to specific needs, which can increase the applicability of the cooking equipment 100.
