Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, specifically to a heating module and its cooking device. The heating module is used to be installed in the cooking device for electromagnetic heating. Background Technology

[0002] In existing heating modules, such as the electromagnetic coil in an induction cooker or rice cooker, magnetic strips are required to guide the direction of the magnetic field generated by the coil wires. The magnetic strips are usually mounted on separate magnetic strip brackets and then installed as independent magnetic strip components on the coil frame. This results in a relatively complex and costly magnetic strip mounting structure for the electromagnetic coil, which is not conducive to the rapid manufacturing of the electromagnetic coil. At the same time, existing magnetic strip components are also prone to causing poor heat dissipation of the coil wires. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the aforementioned related technologies.

[0004] Therefore, the purpose of this utility model is to provide a heating module and its cooking device, mainly to solve the problems of complex magnetic strip installation structure and high cost of existing heating modules.

[0005] The present invention provides a heating module and a cooking device thereof. The heating module of the present invention includes a base bracket, a first coil wire portion provided on the base bracket, and a first pressing wire portion provided on the base bracket. The first pressing wire portion is configured to extend outward toward the side of the base bracket.

[0006] A first pressing area with a clearance structure is formed between the first pressing part and the first coiled part. The first pressing area is configured to be open on the outer side of the side of the seat support, so that the first pressing area is connected to the outer space area of ​​the side of the seat support through the open structure.

[0007] It also includes a magnetic component, which is mounted on the first pressure line portion, and the first pressure line portion is formed to isolate the magnetic component from the first pressure area.

[0008] The number of first pressure lines is set to multiple, and the multiple first pressure lines are arranged in a ring-shaped structure and in an intermittent structure on the support. A first heat dissipation area with an open structure is formed between two adjacent first pressure lines in the ring direction. The heat dissipation area formed by a single first heat dissipation area in the ring direction is larger than the area formed by a single first pressure line in the ring direction.

[0009] The aforementioned heating module is configured with multiple first pressing areas and multiple first heat dissipation areas to form a continuous annular clearance structure in the annular direction for placing and installing the first tightly wound wire group, forming a structure in which the first tightly wound wire group is pressed onto the first coil wire part by the first pressing part for a limited installation.

[0010] In the aforementioned heating module, a limiting part is provided on the side of the first pressure part in the annular direction, so as to form a limiting structure in which the magnetic part and the side wall of the limiting part are in mutual contact when the magnetic part is installed on the first pressure part.

[0011] The aforementioned heating module is configured such that the height of the limiting part is less than the height of the magnetic component, so that a portion of the side position of the magnetic component is exposed relative to the limiting part.

[0012] And / or, the side wall of the limiting part is provided with a heat dissipation part with a recessed structure so that when the magnetic part comes into contact with the side wall of the limiting part, a part of the side position of the magnetic part is exposed relative to the heat dissipation part.

[0013] The aforementioned heating module has a wire part with a protruding structure facing the first coil wire part on one end of the first wire pressing part near the outer edge of the base bracket. The wire part and the first coil wire part are spaced apart to form a wire inlet space height H1.

[0014] Alternatively, the incoming wire space height H1 can be set to be less than the winding space height H2 formed by the first crimping area, or the incoming wire space height H1 can be set to be greater than or equal to the height value H0 formed by a single wire group in the first closely wound wire group and less than the winding space height H2 formed by the first crimping area.

[0015] The aforementioned heating module also has a second coil wire section on the base bracket, which is connected to the first coil wire section to make the base bracket have a concave structure.

[0016] The seat support is provided with a second pressing part that extends toward the outer edge of the seat support. A second pressing area with a clearance structure is formed between the second pressing part and the second coiled part. The second pressing area is configured to be open at an angle to the lower part of the outer edge of the seat support, so that the second pressing area is connected to the outer space area of ​​the outer edge of the seat support through the open structure.

[0017] The number of second pressure lines is set to be multiple. The multiple second pressure lines are arranged in a ring-shaped structure and in a spaced-out structure on the seat bracket. A second heat dissipation area with an open structure is formed between two adjacent second pressure lines in the ring direction.

[0018] Multiple second pressing areas and multiple second heat dissipation areas are configured to form a continuous annular clearance structure in the annular direction for placing and installing the second tightly wound wire assembly.

[0019] The aforementioned heating module is configured such that the heat dissipation area formed by a single second heat dissipation zone in the annular direction is larger than the area formed by a single first pressure line in the annular direction and also larger than the area formed by a single second pressure line in the annular direction.

[0020] Alternatively, the heat dissipation area formed by a single second heat dissipation zone in the circumferential direction may be larger than the heat dissipation area formed by a single first heat dissipation zone in the circumferential direction.

[0021] Alternatively, a magnetic element may also be installed on the second pressure line portion, and the second pressure line portion may be configured to isolate the magnetic element from the second pressure area.

[0022] Alternatively, a structure in which at least a portion of the first and second pressure lines are staggered in the circumferential direction is provided.

[0023] The aforementioned heating module is configured such that the thickness of the winding space formed by the first pressing area is greater than the thickness of the winding space formed by the second pressing area, so that the thickness of the first dense winding group formed in the first pressing area is greater than the thickness of the second dense winding group formed in the second pressing area.

[0024] Alternatively, the cross-section formed by a single wire group in the first tightly wound wire group within the first pressing area is a rectangular structure, and the cross-section formed by a single wire group in the second tightly wound wire group within the second pressing area is a non-rectangular structure, and the thickness of the first tightly wound wire group is greater than the thickness of the second tightly wound wire group.

[0025] Alternatively, the length of the second crimping portion in the extension direction is greater than the length of the first crimping portion in the extension direction, so that the open length of the second crimping area is greater than the open length of the first crimping area, and the thickness of the first tightly wound wire group is greater than the thickness of the second tightly wound wire group.

[0026] Alternatively, the second tightly wound wire group can be configured to have a polygonal structure, while the first tightly wound wire group can be configured to have a non-polygonal structure, and the thickness of the first tightly wound wire group can be greater than the thickness of the second tightly wound wire group.

[0027] In the aforementioned heating module, when the second tightly wound wire group is configured to have a polygonal structure, the outermost ring position of the first tightly wound wire group is set to form a minimum distance L1 and a maximum distance L2 along the radial direction of the support bracket to the innermost ring position of the second tightly wound wire group, and the minimum distance L1 is set to be less than the maximum distance L2.

[0028] The minimum distance L1 is set to be greater than or equal to half the length of the first pressure line in the extension direction, and the maximum distance L2 is set to be less than or equal to the length of the first pressure line in the extension direction.

[0029] The aforementioned heating module also has a receiving portion on its bracket for mounting temperature sensing components;

[0030] It also includes a crimping member, which, when installed on the receiving part, is configured to limit the temperature sensing component to be installed on the receiving part.

[0031] The temperature sensing component is provided with an elastic element, which is located between the pressing member and the receiving part. The pressing member is configured to be able to rotate in the annular direction of the receiving part and move up and down in the vertical direction of the receiving part. When the pressing member moves downward into the receiving part and then rotates at an angle and moves upward under the elastic pushing force of the elastic element, the pressing member is configured to be limited and installed on the receiving part.

[0032] When the crimping member is limited and installed on the receiving part, a first limiting structure is formed between the crimping member and the receiving part to limit the crimping member to be installed on the receiving part in the vertical direction, and a second limiting structure is also formed between the crimping member and the receiving part to limit the crimping member to be installed on the receiving part in the circumferential direction of the receiving part.

[0033] The positions of the first limiting structure and the second limiting structure are arranged at intervals in the annular direction of the accommodating part.

[0034] A cooking apparatus, comprising a main body and a cooking pot, wherein the cooking pot is placed on the main body, characterized in that it further comprises a heating module as described above, wherein the heating module is configured to perform electromagnetic induction heating on the cooking pot.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] In this solution, the first pressing part is fully utilized for the installation structure of the magnetic component. The first pressing part can not only crimp the first tightly wound wire group, but also install the magnetic component. This makes the overall structure simple, low-cost, and convenient for quick installation of the magnetic component, thus facilitating the rapid production and manufacturing of the heating device.

[0037] In this design, the first and second pressure sections perform multiple functions, eliminating the need for a separate structure on the support bracket to install magnetic components. This allows most of the area on the support bracket to better form a heat dissipation zone, thereby improving the heat dissipation effect of the first and second densely wound wire groups.

[0038] In this solution, the installation structure for the magnetic components is simple, eliminating the need for a separate structure for installing the magnetic components. The installation of the magnetic components is achieved by fully utilizing the structure on the bracket to press the first and second pressing parts of the first and second tightly wound wire groups, resulting in a simple installation structure and low cost.

[0039] In this design, the structure of the first pressing part can effectively guide a single wire group to enter the first pressing area for winding and be pressed by the first pressing part, thereby forming a first tightly wound wire group in the first pressing area. This provides better guidance for winding the single wire group and reduces the likelihood of uneven winding caused by the single wire group jumping.

[0040] In this solution, the mounting structure of the first pressure wire part and the magnetic component forms a first heat dissipation area with a large area of ​​heat dissipation, which can realize the first densely wound wire group to dissipate heat over a large area, thereby improving the reliability and stability of the heating module.

[0041] In this solution, the mounting structure of the second pressure wire section and magnetic component forms a second heat dissipation area with a large area of ​​heat dissipation, which can realize the second densely wound wire group to dissipate heat over a large area, thereby improving the reliability and stability of the heating module.

[0042] In this solution, the structural and positional design of the first and second heat dissipation zones enables the first and second closely wound wire groups to dissipate heat over a large area, effectively improving the reliability and stability of the heating module.

[0043] In this scheme, the positional distribution and distance setting of the first and second tightly wound wire groups can make the magnetic field of the heating module relatively independent, reduce the magnetic field interference between the magnetic fields formed by the first and second tightly wound wire groups, and at the same time make the heating module heat the cooking pot more evenly.

[0044] In this solution, the shape, thickness, and other structural settings of the first and second densely wound wire groups enable the heating area corresponding to the first densely wound wire group to be highly efficient when heating the cooking pot, while the heating area corresponding to the second densely wound wire group is large. This facilitates the uniform transfer of heat from the bottom wall to the side wall of the cooking pot, resulting in high overall heating efficiency and good uniform heating effect.

[0045] In this solution, the installation structure of the temperature sensing component is made simple and low-cost, and it does not form a rigid interference fit structure, which greatly reduces the strength of the crimping component during installation, and makes it easier and faster to install or remove the crimping component.

[0046] In this solution, the limiting installation structure of the crimping component has better stability. It achieves the formation of limiting installation structures in the vertical and circumferential directions at two different mutually spaced positions, making the installation structure of the crimping component simpler and more convenient. The crimping component can be easily installed in place without applying a large force, and the limiting structure formed by the crimping component has high stability and reliability.

[0047] In this solution, the crimping component makes installation and disassembly easier, facilitating the maintenance and replacement of the temperature sensing component. The crimping component avoids the problems of difficult disassembly and assembly or damage caused by interference fit, thus achieving lower maintenance costs for the heating module.

Detailed Implementation

[0054] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0055] Example: The heating module and cooking device of this utility model, such as Figures 1 to 5 As shown in the diagram, the heating module simplifies its structure and reduces its cost by incorporating a magnetic component 4 and a heat dissipation structure. This facilitates the manufacturing of the heating module, improves production efficiency, and enhances its heat dissipation performance when installed in the cooking appliance.

[0056] The heating module of this solution includes a base bracket 1, which has a disc-shaped or ring-shaped structure. A first coiled wire portion 101 and a first pressing wire portion 103 are also provided on the base bracket 1. The first pressing wire portion 103 is located on the first coiled wire portion 101 and extends outwards towards the side of the base bracket 1. A first pressing area 107 with a clearance structure is formed between the first pressing wire portion 103 and the first coiled wire portion 101. The first pressing area 107 is open towards the side of the base bracket 1, thus connecting the first pressing area 107 to the outer space of the side of the base bracket 1. This allows a single wire group to enter the first pressing area 107 from outside the base bracket 1 for winding, achieving a disc-shaped wire group wound within the first pressing area 107. Additionally... The thermal module also includes a magnetic component 4, which is mounted on the first pressing part 103. The first pressing part 103 is configured to isolate the magnetic component 4 from the first pressing area 107. Specifically, the lower end face of the first pressing part 103 and the upper surface of the first coiled wire part 101 form the first pressing area 107. The magnetic component 4 can be mounted on the upper end face of the first pressing part 103. This allows the thickness of the first pressing part 103 to isolate the magnetic component 4 from the first pressing area 107. When a single wire group enters the first pressing area 107 for forming, the single wire group will not contact the magnetic component 4. By mounting the magnetic component 4 on the first pressing part 103, the structure of the first pressing part 103 is fully utilized, eliminating the need for a separate structure for mounting the magnetic component 4 on the bracket 1. This results in a simple overall structure, low cost, and convenient installation of the magnetic component 4.

[0057] The first pressing part 103 is configured to be multiple, and the multiple first pressing parts 103 are arranged in a ring-shaped and spaced-apart structure on the support bracket 1. A first heat dissipation area 105 with a clearance structure is formed between two adjacent first pressing parts 103 in the ring direction. The heat dissipation area formed by a single first heat dissipation area 105 in the ring direction is larger than the area formed by a single first pressing part 103 in the ring direction. Specifically, the multiple first pressing parts 103 are spaced apart in the ring direction to form multiple positions for crimping a single wire group, so that the single wire group can be wound and shaped in the first crimping area 107. At the same time, multiple first pressing parts 103 form multiple first... The heat dissipation area 105 is an effective heat dissipation area for single wires wound in the first crimping area 107 after being formed. It is mainly used by the heating module to dissipate heat after single wires are wound in the first crimping area 107 during operation. The structure of the first heat dissipation area 105 provides a larger heat dissipation area. At the same time, the structure of the first crimping part 103 for mounting the magnetic component 4 eliminates the need for a separate structure for mounting the magnetic component 4 on the bracket 1. This allows most of the area on the bracket 1 to better form a heat dissipation area, making the area of ​​the first heat dissipation area 105 larger and thus improving the heat dissipation effect of the wires wound in the first crimping area 107 on the heating module.

[0058] It can be seen that by making full use of the first crimping part 103 in the mounting structure of the magnetic component 4, the first crimping part 103 can not only crimp the first tightly wound wire group 2, but also install the magnetic component 4, making the overall structure simple, low cost, and convenient for quick installation of the magnetic component 4.

[0059] In this scheme, multiple first pressing areas 107 and multiple first heat dissipation areas 105 are set to form a continuous annular clearance structure in the annular direction for placing and installing the first tightly wound wire group 2. The first tightly wound wire group 2 is pressed by the first pressing part 103 onto the first coil part 101 in a limited installation structure. When a single wire group enters the first pressing area 107, it will be wound, that is, wound within the continuous annular clearance structure, and thus formed into the first tightly wound wire group 2. The first tightly wound wire coil has a disc-shaped or circular structure and is pressed by multiple first pressing parts 103 into the continuous annular clearance structure formed by the first pressing area 107 and the first heat dissipation area 105, so as to press the first tightly wound wire group 2 between the first pressing part 103 and the first coil part 101 for forming, thereby realizing the winding and forming of the first tightly wound wire group 2. At the same time, the first tightly wound wire group 2 is cooled by the first heat dissipation area 105.

[0060] In order to better limit the installation of the magnetic component 4, the first pressure part 103 in this solution is provided with a limiting part 109 on the side in the annular direction. This is configured such that when the magnetic component 4 is installed on the first pressure part 103, the magnetic component 4 and the side wall of the limiting part 109 are in mutual contact. When the magnetic component 4 is installed on the end face of the first pressure part 103, the limiting part 109 can limit the magnetic component 4 in the annular direction to prevent the magnetic component 4 from moving or deviating in the annular direction.

[0061] Optionally, the first pressure part 103 is provided with limiting parts 109 on both sides in the annular direction to limit the magnetic element 4 in both the clockwise and counterclockwise directions in the annular direction.

[0062] In order to improve the heat dissipation effect of the magnetic component 4, in this solution, the height of the limiting part 109 is set to be less than the height of the magnetic component 4, so that a part of the side position of the magnetic component 4 is exposed relative to the limiting part 109. This makes the upper surface position and a part of the side surface of the magnetic component 4 exposed when the magnetic component 4 is installed in place, thereby enabling better heat dissipation.

[0063] And / or, in order to improve the heat dissipation effect of the magnetic component 4, in this solution, a heat dissipation part with a recessed structure is provided on the side wall of the limiting part 109 so that when the magnetic component 4 comes into contact with the side wall of the limiting part 109, a part of the side position of the magnetic component 4 is exposed relative to the heat dissipation part. The heat dissipation part can be used to dissipate heat from the side position of the magnetic component 4 so that the magnetic component 4 has a larger heat dissipation area for better heat dissipation when it is installed in place.

[0064] To better guide the single wire group into the first crimping area 107 for winding, and to improve the tightness and stability of the first tightly wound wire group 2 during winding, this design provides a guide wire portion 110 with a protruding structure facing the first coiled wire portion 101 at one end of the first crimping portion 103 near the outer edge of the support bracket 1. The guide wire portion 110 and the first coiled wire portion 101 are spaced apart to form an entry space height H1. The entry space height H1 allows the single wire group to enter the first crimping area 107 from outside the support bracket 1. The guide wire portion 110 guides and restricts the single wire group, preventing bouncing or jerking during entry, thus guiding the single wire group and limiting its entry into the first crimping area 107 with minimal wobbling. The winding process is carried out within the crimping area 107 to form the first densely wound wire group 2. Specifically, the height H1 of the incoming wire space is set to be less than the height H2 of the winding space formed by the first crimping area 107, or the height H1 of the incoming wire space is set to be greater than or equal to the height H0 formed by a single wire group in the first densely wound wire group 2 and less than the height H2 of the winding space formed by the first crimping area 107. This allows the single wire group to be guided more stably to move into the first crimping area 107 for winding at the incoming wire space height H1, making it less likely to bounce or jerk. This results in better stability of the single wire group entering the first crimping area 107, thereby achieving a tighter and more stable connection between adjacent single wire groups in the first densely wound wire group 2, reducing the likelihood of misalignment or large gaps.

[0065] Optionally, the lower end of the conductor portion 110 is configured to have a circular or spherical structure.

[0066] In this design, the support 1 is also provided with a second coil section 102. The second coil section 102 is configured as a ring or circular structure. The second coil section 102 is connected to the first coil section 101 so that the support 1 has a concave structure. That is, the support 1 forms a concave structure in the shape of a disc or ring. The concave structure makes the support 1 a three-dimensional plate structure, which can heat the bottom and side walls of the cooking pot and achieve a three-dimensional heating effect.

[0067] Specifically, a second pressing part 104 extending towards the outer edge of the seat support 1 is provided on the seat support 1. A second pressing area 108 with a clearance structure is formed between the second pressing part 104 and the second coiled part 102. The second pressing area 108 is configured to be open diagonally downward towards the outer edge of the seat support 1, so that the second pressing area 108 is connected to the outer space area of ​​the outer edge of the seat support 1 through the open structure. This allows a single wire group to enter the second pressing area 108 from the outside of the seat support 1 for winding, realizing that a single wire group is wound into a coiled structure in the second pressing area 108. The number of second pressing parts 104 is set to be multiple, and the multiple second pressing parts 104 are arranged in a ring structure and spaced apart on the seat support 1. Adjacent second pressing parts 104 are arranged in a ring structure and spaced apart. A second heat dissipation area 106 with a clearance structure is formed between the pressing sections 104 in the annular direction; multiple second pressing sections 108 and multiple second heat dissipation areas 106 are provided to form a continuous annular clearance structure in the annular direction for placing and installing the second tightly wound wire group 3. The continuous annular clearance structure is used for winding a single wire group to form a space area for placing the second tightly wound wire group 3. The second pressing section 104 forms a structure for pressing the second tightly wound wire group 3, realizing the pressing of the second tightly wound wire group 3 between the second pressing section 104 and the second coil section 102 for forming. The single wire group enters the second pressing section 108 through the open structure of the second pressing section 108 for winding. The formed second tightly wound wire group 3 is located in the continuous annular clearance structure, thereby realizing the winding of the second tightly wound wire group 3.

[0068] Optionally, the plurality of second pressure lines 104 are evenly distributed in the annular direction.

[0069] Optionally, the second pressing part 104 extends outward along the radial direction of the seat bracket 1 toward the outer edge of the seat bracket 1 to form the second pressing area 108 which opens obliquely downward along the radial direction of the seat bracket 1 toward the outer edge of the seat bracket 1, so as to form the second tightly wound wire group 3 into a concave structure after being wound, thereby forming a three-dimensional heating effect on the cooking pot.

[0070] Optionally, in order to better guide the single wire group into the second crimping area 108 for winding, and to improve the tightness and stability of the second closely wound wire group 3 during the winding process, a conductor part 110 is also provided on the second crimping part 104. The conductor part 110 has the same structure as the conductor part 110 on the first crimping part 103 and achieves the same technical effect.

[0071] To further enhance the heat dissipation effect of the second closely wound wire group 3, in this scheme, the heat dissipation area formed by a single second heat dissipation area 106 in the annular direction is larger than the area formed by a single first pressure wire part 103 in the annular direction and larger than the area formed by a single second pressure wire part 104 in the annular direction; this can form a larger heat dissipation area of ​​the second closely wound wire group 3 in the annular direction, which can dissipate heat more effectively.

[0072] To further enhance the heat dissipation effect of the second closely wound wire group 3, in this scheme, the heat dissipation area formed by a single second heat dissipation area 106 in the annular direction is set to be larger than the heat dissipation area formed by a single first heat dissipation area 105 in the annular direction; thus forming a larger heat dissipation area in the annular direction for the second closely wound wire group 3, which can dissipate heat more effectively.

[0073] In this solution, in order to further improve the heat dissipation effect of the first closely wound wire group 2 and the second closely wound wire group 3, at least a portion of the first pressing wire portion 103 and the second pressing wire portion 104 are arranged in a staggered distribution in the annular direction. The staggered structure allows at least a portion of the first heat dissipation area 105 and the second heat dissipation area 106 to also form a staggered structure, thereby improving the heat dissipation effect of the heating module and improving the stability and reliability of the operation of the first closely wound wire group 2 and the second closely wound wire group 3.

[0074] In this scheme, a magnetic component 4 can also be provided to guide the magnetic field generated by the second tightly wound wire group 3. The second pressing part 104 can also be equipped with a magnetic component 4, and the second pressing part 104 can be configured to isolate the magnetic component 4 from the second pressing area 108. By also installing a magnetic component 4 on the second pressing part 104, the second pressing part 104 can also have multiple functions. The second pressing part 104 can not only press the second tightly wound wire group 3, but also install the magnetic component 4, making the overall structure simple, low cost, and convenient for quick installation of the magnetic component 4. The magnetic component 4 on the second pressing part 104 can better guide the magnetic field generated by the second tightly wound wire group 3.

[0075] For the structure in which the magnetic component 4 is mounted on the first pressure wire portion 103, an adhesive portion can be provided between the first pressure wire portion 103 and the magnetic component 4 to bond and fix the magnetic component 4 to the first pressure wire portion 103. The adhesive layer can bond and fix the magnetic component 4 to the upper end face of the first pressure wire portion 103, and the bonded and fixed structure is stable and reliable.

[0076] Preferably, a pre-adhesive groove is provided on the upper end face of the first pressure part 103. The pre-adhesive groove is used for pre-applying adhesive. This can limit the bonding position of the magnetic component 4 on the first pressure part 103, prevent the adhesive layer from overflowing, and prevent the adhesive layer from being too thick, causing the magnetic component 4 to be too far away from the first tightly wound wire group 2. This improves the stability and consistency of bonding and fixing multiple magnetic components 4 to multiple first pressure parts 103 respectively.

[0077] Alternatively, a locking part can be provided between the first pressure part 103 and the magnetic component 4 to form a magnetic component 4 that is locked and fixed on the first pressure part 103. The magnetic component 4 is placed on the first pressure part 103 for locking and limiting fixation, thereby realizing the installation and placement of the magnetic component 4.

[0078] The structure in which the magnetic component 4 is mounted on the second pressure part 104 can be the same as the structure in which the magnetic component 4 is mounted on the first pressure part 103. An adhesive layer or a locking part can be provided to fix the magnetic component 4 to the second pressure part 104.

[0079] To further improve the heating efficiency and uniform heating effect of the heating module in heating the cooking pot, this solution sets the thickness of the winding space formed by the first pressing area 107 to be greater than the thickness of the winding space formed by the second pressing area 108. This makes the thickness of the first densely wound wire group 2 formed in the first pressing area 107 greater than the thickness of the second densely wound wire group 3 formed in the second pressing area 108. This allows for relatively concentrated heating of the bottom wall of the cooking pot, resulting in high heating efficiency, while the side wall of the cooking pot can be heated over a relatively large area. This facilitates the transfer and diffusion of heat between the bottom and side walls of the cooking pot. During the heating process, the first densely wound wire group 2 can rapidly heat the liquid in the cooking pot, while the second densely wound wire group 3 can diffuse the heat of the liquid in the cooking pot towards the inner side wall of the cooking pot. After the liquid boils, multiple boiling points can be formed in the cooking pot, thus achieving a better uniform heating effect.

[0080] To further improve the heating efficiency and uniform heating effect of the heating module on the cooking pot, this solution sets the cross-section of a single wire group in the first tightly wound wire group 2 within the first pressing area 107 to a rectangular structure, and sets the cross-section of a single wire group in the second tightly wound wire group 3 within the second pressing area 108 to a non-rectangular structure. The thickness of the first tightly wound wire group 2 is greater than the thickness of the second tightly wound wire group 3. The rectangular cross-section of the first tightly wound wire group 2 results in higher heating efficiency and better concentrated heating in the bottom wall area of ​​the cooking pot corresponding to the first tightly wound wire group 2. Meanwhile, the side walls of the cooking pot can be heated over a relatively large area, facilitating heat transfer and diffusion between the bottom and side walls. During heating, the first tightly wound wire group 2 enables the liquid in the cooking pot to heat up rapidly, while the second tightly wound wire group 3 enables the liquid in the cooking pot to diffuse and heat up inwards. After the liquid boils, multiple boiling points can be formed in the cooking pot, thus achieving a better uniform heating effect.

[0081] To further improve the heating efficiency and uniform heating effect of the heating module on the cooking pot, in this solution, the length of the second pressing part 104 in the extending direction is greater than the length of the first pressing part 103 in the extending direction, so that the open length of the second pressing area 108 is greater than the open length of the first pressing area 107, and the thickness of the first tightly wound wire group 2 is greater than the thickness of the second tightly wound wire group 3. This makes the heating area formed by the second tightly wound wire group 3 in the extending direction greater than the heating area of ​​the first tightly wound wire group 2 in the extending direction, resulting in higher heating efficiency and better relatively concentrated heating effect in the bottom wall area of ​​the cooking pot corresponding to the first tightly wound wire group 2, while the side wall of the cooking pot has a larger heating area for diffused heating, which is conducive to the transfer and diffusion of heat between the bottom wall and the side wall of the cooking pot. During the heating process, the first tightly wound wire group 2 can realize the rapid heating of the liquid in the cooking pot, while the second tightly wound wire group 3 can realize the diffused heating of the liquid in the cooking pot towards the inward side. After the liquid boils, multiple boiling points can be formed in the cooking pot, thereby achieving a better uniform heating effect.

[0082] To further improve the efficiency and uniformity of the heating module in heating the cooking pot, this solution sets the second tightly wound wire group 3 to a polygonal structure while the first tightly wound wire group 2 is set to a non-polygonal structure, with the thickness of the first tightly wound wire group 2 being greater than the thickness of the second tightly wound wire group 3. When the second tightly wound wire group 3 has a polygonal structure, an angle is formed at the intersection of any two adjacent sides of the polygonal structure. At this angle, the heating area of ​​the cooking pot is extended, and a more concentrated magnetic field is formed at this angle, thereby extending the heating area on the cooking pot, i.e., increasing the heating area. This increases the heating range of the second tightly wound wire group 3 on the side wall area of ​​the cooking pot, achieving a larger heating area. Simultaneously, it improves the uniformity of heating the cooking pot. Multiple extended heating areas are formed on the side wall, which together with the areas in the second tightly wound coil group 3 (excluding the included angle) form a larger heating area. At the same time, multiple areas for heat diffusion are formed, which helps to improve the uniformity of heating the cooking pot by the second tightly wound coil group 3. The non-polygonal structure and relatively large thickness of the first tightly wound coil group 2 make the heating efficiency of the bottom wall area of ​​the cooking pot corresponding to the first tightly wound coil group 2 higher and the heating effect of relatively concentrated heating better. The side wall of the cooking pot has a larger heating area for diffusion heating, which is conducive to the transfer and diffusion of heat between the bottom wall and the side wall of the cooking pot. During the heating process, the first tightly wound coil group 2 can realize the rapid heating of the liquid in the cooking pot, while the second tightly wound coil group 3 can realize the diffusion heating of the liquid in the cooking pot towards the inward side. After the liquid boils, multiple boiling points can be formed in the cooking pot, thereby achieving a better uniform heating effect.

[0083] To further reduce magnetic field interference between the first tightly wound wire group 2 and the second tightly wound wire group 3, and to improve the uniform heating effect and heating area of ​​the heating module for the cooking pot, in this solution, when the second tightly wound wire group 3 is configured as a polygon, the outermost ring of the first tightly wound wire group 2 is arranged radially from the support bracket 1 to the innermost ring of the second tightly wound wire group 3 to form a minimum distance L1 and a maximum distance L2, with the minimum distance L1 being less than the maximum distance L2. It can be understood that, if the second tightly wound wire group 3 is a polygon and the first tightly wound wire group 2 is a circle, the intersection (angle) between any two adjacent sides of the polygon in the second tightly wound wire group 3 is arranged radially to the outer edge of the first tightly wound wire group 2 to form the maximum distance L2, while the midpoint of any side of the second tightly wound wire group 3 is arranged radially to the outer edge of the first tightly wound wire group 2 to form the minimum distance L1. Because the second tightly wound wire group 3 has a polygonal structure and the first tightly wound wire group 2 has a circular structure, the maximum distance L2 and the minimum distance L1 formed are not equal. The minimum distance L1 is set to be greater than or equal to half the length of the first pressing part 103 in the extension direction, and the maximum distance L2 is set to be less than or equal to the length of the first pressing part 103 in the extension direction. In this way, the interval between the first tightly wound wire group 2 and the second tightly wound wire group 3 is relatively moderate, and the intervals at multiple positions are not equal. This makes the magnetic field interference between the first tightly wound wire group 2 and the second tightly wound wire group 3 relatively low. The magnetic field of the first tightly wound wire group 2 and the magnetic field of the second tightly wound wire group 3 can remain relatively independent, and at the same time, they are not too far apart in the radial direction. This allows the heat on the bottom wall and the side wall of the cooking pot to be transferred and diffused more effectively, thereby improving the uniformity of heating the cooking pot.

[0084] Preferably, the second tightly wound wire group 3 is configured to have a hexagonal structure.

[0085] Preferably, the second closely wound wire group 3 is configured to have an octagonal structure.

[0086] When the second tightly wound wire group 3 has a polygonal structure, an angle is formed at the intersection of any two adjacent sides of the polygonal structure. At this angle, the heating area of ​​the cooking pot is extended, and a more concentrated magnetic field is formed at this angle, thereby extending the heating area on the cooking pot and increasing the heating area. This increases the heating range of the side wall area of ​​the cooking pot by the second tightly wound wire group 3, resulting in a larger heating area. At the same time, it improves the uniformity of heating the cooking pot, forming multiple extended heating areas on the side wall of the cooking pot. These extended heating areas, together with the areas of the second tightly wound wire group 3 other than the angled areas, form a larger heating area and multiple areas for heat diffusion, which helps to improve the uniformity of heating the cooking pot by the second tightly wound wire group 3.

[0087] In this solution, the heating module also includes a temperature sensing component 5, which is used to detect the temperature of the cooking pot. In the prior art, the temperature sensing component 5 is generally fixed to the base bracket 1 with screws, or the temperature sensing component 5 is installed on the base bracket 1 by setting a rigid interference fit between the temperature sensing component 5 and the base bracket 1. The above-mentioned installation structure for the temperature sensing component 5 is relatively complex and costly. In addition, the rigid interference fit requires a large external force to install the temperature sensing component 5, and a large external force is also required to disassemble the temperature sensing component 5. The previous method involved using force to install and remove the temperature sensing component 5, which was inconvenient and prone to damage to the component or the support plate. It also made maintenance difficult and prevented easy and convenient installation of the temperature sensing component 5. The installation limiting structure for the temperature sensing component 5 in this solution addresses one of these problems, enabling convenient, easy, and quick installation at a low cost. The temperature sensing component 5 and the support plate 1 are less prone to damage, and the temperature sensing component 5 can be easily installed without the need for a rigid interference fit.

[0088] Specifically, the support bracket 1 is also provided with a receiving portion 111 for mounting the temperature sensing component 5. The receiving portion 111 is configured as a ring structure and is mainly located at the center of the support bracket 1, that is, at the center of the first coil portion 101. It is a structural part for limiting and mounting the temperature sensing component 5 in place. The heating module also includes a pressing member 6, which is an independent component structure. When the pressing member 6 is installed on the receiving portion 111, it is configured to limit and mount the temperature sensing component 5 on the receiving portion 111. When the pressing member 6 is installed in place by external force, the pressing member 6 forms a structure that limits the temperature sensing component 5 on the receiving portion 111 in the vertical direction, thereby realizing the limiting and mounting structure of the temperature sensing component 5.

[0089] The temperature sensing component 5 is provided with an elastic element 7, which can be a spring. The elastic element 7 is located between the pressing member 6 and the receiving portion 111. The pressing member 6 is configured to rotate within the receiving portion 111 along the annular direction and move up and down along the vertical direction of the receiving portion 111. When the pressing member 6 moves downward into the receiving portion 111, rotates at an angle, and moves upward under the elastic pushing force of the elastic element 7, the pressing member 6 is configured to be fixedly installed on the receiving portion 111. Specifically, the pressing member 6 can move up and down on the receiving portion 111, or it can move clockwise or counterclockwise along the annular direction on the receiving portion 111. During the installation of the pressing member 6, a downward external force is first applied to the pressing member 6 to compress the elastic element 7 and enter the receiving portion. On 111, after moving downward a certain distance, a rotational force can be applied to the crimping member 6 to make it move in the annular direction. When the rotational movement reaches a certain angle, it has moved a certain distance in the annular direction. Then, the external force applied to the crimping member 6 is removed. At this time, under the elastic force of the elastic member 7, the elastic member 7 pushes the crimping member 6 upward to move a certain distance. When the crimping member 6 moves upward into place, it is limited and installed in the receiving part 111. When applying downward and rotational forces to the crimping member 6, no excessive external force is required. It is only necessary to gently move the crimping member 6 downward and rotate it in the annular direction. No interference fit is performed during the entire process, so no large external force is required. This allows the crimping member 6 to be easily and quickly limited and installed in the receiving part 111.

[0090] Specifically, when the crimping member 6 is positioned and installed on the receiving portion 111, a first limiting structure 112 is formed between the crimping member 6 and the receiving portion 111 to limit the crimping member 6 to be installed on the receiving portion 111 in the vertical direction, mainly by limiting a portion of the crimping member 6 to be installed within the receiving portion 111. Furthermore, a second limiting structure 113 is formed between the crimping member 6 and the receiving portion 111 to limit the crimping member 6 to be installed on the receiving portion 111 in the circumferential direction, mainly by limiting a portion of the crimping member 6 to be installed within the receiving portion 111. The positions of the first limiting structure 112 and the second limiting structure 113 are arranged at intervals in the circumferential direction of the receiving portion 111. The first limiting structure 112 and the second limiting structure 113 form limiting structures for the crimping member 6 in the vertical and circumferential directions at different intervals, avoiding interference fits at the same position. Specifically, the receiving portion 111 is provided with a laterally extending first protrusion, and the crimping member 6 is provided with a corresponding laterally extending second protrusion. When the crimping member 6 enters the receiving portion 111 downwards and rotates at a certain angle, the second protrusion is located below the first protrusion. When the crimping member 6 rotates to its position and moves upwards under the elastic pushing force of the elastic member 7, the lower end face of the first protrusion and the upper end face of the second protrusion contact each other in the vertical direction to form a contact limiting structure, which is the first protrusion and the second protrusion forming a contact limiting structure. As the first limiting structure 112, no interference fit structure is formed in the vertical direction. Under the contact limiting structure of the first and second protrusions, the crimping member 6 is limited and fixed in the vertical direction on the receiving part 111. A part of the crimping member 6 is limited within the receiving part 111, and the limiting structure is mainly formed in the upward direction in the vertical direction to prevent the crimping member 6 from detaching from the receiving part 111 upward. The receiving part 111 is also provided with a downwardly protruding third protrusion, and the crimping member 6 is correspondingly provided with a downwardly recessed fourth recess. When an external force is applied downward to the crimping member 6, the downward movement distance is greater than the downward protrusion height of the third protrusion. At this time, the fourth recess on the crimping member 6 will be located below the third protrusion. The rotating pressing member 6 rotates, and the angle of rotation of the pressing member 6 forms a distance of rotation in the annular direction, so that the fourth concave part is located directly below the third convex part. At this time, the external force applied to the pressing member 6 is removed, and the pressing member 6 moves upward under the elastic pushing force of the elastic member 7, so that the fourth concave part moves upward and forms the third convex part wrapped or sleeved by the fourth concave part, that is, a limiting structure is formed in the clockwise and counterclockwise directions in the annular direction. The wrapping or sleeved structure forms a contact limiting structure, so an interference fit structure is not formed in the vertical direction. At this time, the pressing member 6 cannot rotate within the receiving part 111, and the third convex part and the fourth concave part form the second limiting structure 113.It is understandable that the first limiting structure 112 is ultimately formed after the pressing member 6 moves downward and rotates, and then moves upward to its final position. Therefore, by placing the first limiting structure 112 and the second limiting structure 113 at two different, mutually spaced positions in the annular direction of the receiving portion 111, limiting structures can be formed in the vertical and annular directions respectively. This makes the installation of the pressing member 6 easier, eliminating the need for interference fit. The contact limiting and wrapping limiting structures only require the pressing member 6 to move downward and rotate to achieve the limiting installation structure for the temperature sensing component 5. That is, after the pressing member 6 is limited and installed on the receiving portion 111, the pressing member 6 forms the limiting structure for the temperature sensing component 5, thus limiting the temperature sensing component 5 within the receiving portion 111.

[0091] Specifically, regarding the vertical limiting structure of the crimping member 6, the first limiting structure 112 limits the crimping member 6 in the upward direction in the vertical direction. That is, the crimping member 6 is limited and fixed in the receiving portion 111 in the upward direction and will not detach from the receiving portion 111. The elastic member 7 is located between the crimping member 6 and the temperature sensing component 5 to form a vertical limiting structure for the crimping member 6 in the downward direction. That is, the elastic member 7 has an elastic pushing force on the crimping member 6 in the upward direction, thus limiting the crimping member 6 in the downward direction within the receiving portion 111. Of course, the elastic member 7 has elastic force in the vertical direction and can be compressed or extended. When the crimping member 6 is... During installation, an external force can be applied to the crimping member 6. When the crimping member 6 is subjected to a downward external force, it can compress the elastic member 7 and move downward. At this time, the crimping member 6 can be moved downward into the receiving part 111 for installation. At the same time, a rotational force can be applied to the crimping member 6. When the crimping member 6 rotates at a certain angle, the rotational force on the crimping member 6 can be canceled. At this time, the crimping member 6 will be driven upward by the elastic pushing force of the elastic member 7 to move into place and realize the installation of the crimping member 6. When installed in place, a first limiting structure 112 is formed between the crimping member 6 and the receiving part 111, that is, an upward and downward limiting installation structure is formed in the vertical direction.

[0092] Specifically, regarding the vertical limiting installation structure of the temperature sensing component 5, a stepped portion is provided at the front end of the temperature sensing component 5. When the temperature sensing component 5 is placed inside the receiving portion 111, the stepped portion and the support portion on the receiving portion 111 contact each other to form a downward limiting structure in the vertical direction, preventing the temperature sensing component 5 from detaching from the receiving portion 111 in the downward direction. Combined with the elastic member 7 located between the pressing member 6 and the receiving portion 111, the pressing member 6, through the elastic member 7, forms a limiting structure for the upward direction of the temperature sensing component 5 in the vertical direction, thus achieving the limiting of the temperature sensing component 5 in both the upward and downward directions in the vertical direction. The mounting structure includes a pressing member 6 that primarily forms a vertically upward limiting structure for the temperature sensing component 5. An elastic member 7 is located between the pressing member 6 and the temperature sensing component 5. The temperature sensing component 5 is placed within the receiving portion 111 via the elastic member 7, enabling the temperature sensing component 5 to move vertically. Specifically, when the pressing member 6 moves downward, it compresses the elastic member 7, pressing the temperature sensing component 5 into the receiving portion 111. During the installation of the pressing member 6, the elastic member 7 can also push the pressing member 6 upward, ensuring it is installed in place and achieving a limiting installation effect.

[0093] The temperature sensing component 5 in this solution includes a temperature sensing bracket and a temperature sensing cap. The temperature sensing cap is installed on the temperature sensing bracket, and a temperature sensing sensor is also installed on the temperature sensing bracket. The temperature sensing sensor is located on the bottom end face inside the temperature sensing cap to detect the temperature on the temperature sensing cap. When the temperature sensing cap comes into contact with the cooking pot, the temperature of the cooking pot is transferred to the temperature sensing cap and is contacted by the temperature sensing sensor, thus achieving the effect of detecting the temperature of the cooking pot.

[0094] The temperature sensing component 5 is also equipped with a connecting wire, which is connected to the temperature sensing sensor for electrical connection with the control module, so as to realize the signal feedback transmission of the detected temperature. In order to facilitate the connection of the connecting wire, a wire hole is also provided on the crimping member 6 for the connecting wire on the temperature sensing component 5 to pass through. The connecting wire passes through the wire hole to pass through the crimping member 6 to realize electrical connection with the external control module.

[0095] Specifically, the temperature-sensing bracket and the temperature-sensing cap can move up and down in the vertical direction together. When the cooking pot presses down on the temperature-sensing cap, the temperature-sensing bracket and the temperature-sensing cap move together toward the pressing member 6 to compress the elastic member 7. When the cooking pot is removed, the temperature-sensing bracket and the temperature-sensing cap move together away from the pressing member 6 under the elastic pushing force of the elastic member 7 to reset to the installed structure. In this process, the temperature-sensing component 5 achieves the effect of detecting the temperature of the cooking pot.

[0096] The cooking device includes a main body and a cooking pot, with the cooking pot placed on the main body. It also includes a heating module as described above, configured to electromagnetically induction heat the cooking pot. The heating module is installed inside the main body. During the operation of the cooking device, the temperature sensing component 5 detects the temperature on the cooking pot, and the heating module electromagnetically induction heats the cooking pot, enabling the cooking device to cook food.

[0097] In this solution, the cooking device can be a rice cooker, induction cooker, or electric pressure cooker, or other kitchen appliances that require electromagnetic induction heating. As long as the heating module of this solution is set accordingly, the technical effect of this solution can be achieved.

[0098] For any aspects not covered in this solution, existing technologies can be used or referenced.

[0099] Working Principle: The heating module of this solution utilizes a structure on the first pressing part 103, which is used to press the first tightly wound wire group 2, to mount a magnetic component 4. This simplifies the mounting structure of the magnetic component 4, reducing costs. The bracket 1 does not require a separate structure for mounting the magnetic component 4. The first pressing part 103 not only serves to press the first tightly wound wire group 2 downwards but also to mount the magnetic component 4, while simultaneously isolating the magnetic component 4 from the first tightly wound wire group 2. Similarly, a magnetic component 4 can also be mounted on the second pressing part 104, enabling the second pressing part 104 to not only press downwards but also to mount the magnetic component 4. The second tightly wound wire group 3, which is pressed together, also serves to install the magnetic component 4. The installation structure of the magnetic component 4 is simple and low in cost. At the same time, the structure of the first pressing part 103 and the second pressing part 104 eliminates the need for other separate structures on the support bracket 1 to install the magnetic component 4. This allows the support bracket 1 to form a large heat dissipation area, the first heat dissipation area 105 and the second heat dissipation area 106. This enables the first tightly wound wire group 2 and the second tightly wound wire group 3 to dissipate heat more effectively, preventing heat concentration. When the heating module is installed on the cooking device, it can effectively dissipate heat, improving its reliability and stability.

[0100] Those skilled in the art will understand that the above embodiments are specific implementations of the present utility model. In practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present utility model, and all such changes are within the protection scope of the present utility model.
