Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cooking equipment, and in particular to a bracket assembly and a cooking equipment. Background Art
[0002] In the related art, for cooking equipment such as rice cookers with electromagnetic heating, one or more coils need to be set opposite to the metal cookware. The coils generate a high-frequency alternating magnetic field, which acts on the metal cookware to form eddy currents to achieve self-heating of the cookware.
[0003] When producing and assembling such cooking equipment, the coils need to be wound one by one, and the production process is complicated. Utility Model Content
[0004] The present application aims to solve at least one of the technical problems existing in the prior art or related art.
[0005] To this end, a first aspect of the present application provides a bracket assembly.
[0006] A second aspect of the present application provides a cooking device.
[0007] In view of this, the first aspect of the present application provides a bracket assembly, including: a first bracket, the first bracket includes a accommodating cavity, the accommodating cavity is used to accommodate an inner pot, and the first bracket is used to wind a side coil; a chassis, the chassis is detachably connected to the first bracket; a second bracket, the second bracket is connected to the chassis, the first bracket and the second bracket are respectively located on both sides of the chassis, and the second bracket is used to wind a bottom coil.
[0008] In the technical solution, the cooking device includes a bracket assembly, and exemplarily, the bracket assembly is a coil disc bracket for winding the bottom coil and the side coil. The bracket assembly includes a first bracket, a chassis, and a second bracket, and the first bracket and the chassis are separately arranged. Among them, the first bracket includes a receiving cavity, and when the cooking device is cooking, the inner pot is placed at a specific position in the receiving cavity, and the side coil is wound on the first bracket, so that when the inner pot is placed in the receiving cavity, the side coil is located outside the side wall of the inner pot.
[0009] The second bracket is connected to the first bracket through the bottom plate, wherein the second bracket and the first bracket are respectively located on both sides of the bottom plate. The bottom coil is wound around the second bracket, and the bottom plate is located at the bottom of the first bracket, so that when the inner pot is placed in the accommodating cavity, the bottom coil can be arranged toward the bottom wall of the inner pot.
[0010] By arranging the first bracket and the second bracket separately, when producing or assembling the cooking device, the side coils can be independently wound on the first bracket, and the bottom coils can be independently wound on the second bracket on the chassis. After the winding is completed, the chassis with the second bracket is assembled with the first bracket.
[0011] For example, the number of the second brackets is the same as the number of the bottom coils. When the cooking device is produced and assembled, the bottom coils are wound one by one on the plurality of second brackets on the chassis. At the same time, the side coils are wound on the first bracket alone. After the side coils on the first bracket and the bottom coils on the second bracket are wound, the first bracket and the chassis are assembled, and the bottom coils and the side coils are wired, thereby realizing modular production.
[0012] The present application simplifies the assembly process of the cooking equipment and improves modular production efficiency by using the split-design first bracket and second bracket.
[0013] In addition, the bracket assembly in the above technical solution provided by the present application may also have the following additional technical features:
[0014] In some technical solutions of the present application, optionally, a limiting rib is provided at the bottom of the first bracket, and the limiting rib includes a slot; the chassis is provided with a mounting portion opposite to the limiting rib, and the mounting portion includes a clamping portion, and the clamping portion is clamped in the slot.
[0015] In this technical solution, a limiting rib is provided at the bottom of the first bracket, and the chassis includes a mounting portion that is opposite to the limiting rib. When the first bracket and the chassis are connected, the limiting rib cooperates with the mounting portion to fix the relative position of the first bracket and the chassis, so that after assembly, the position of the bottom coil and the inner pot can be relatively fixed. A clamping groove is provided on the limiting rib, and a clamping portion is provided on the mounting portion. When the first bracket and the chassis are assembled and fixed, the first bracket and the chassis are fixed by clamping the clamping portion into the clamping groove.
[0016] Exemplarily, the limiting rib is a raised cylindrical structure, and the mounting portion is a through hole matching the shape of the cylindrical structure. A transverse slot is provided on the cylindrical structure, and an avoidance portion is provided at the starting position of the transverse slot. A latching tooth is provided on the side wall of the through hole, and the latching tooth is the above-mentioned latching portion. When assembling the first bracket and the chassis, the cylindrical structure is passed through the through hole, and the latching tooth on the through hole enters the slot through the avoidance portion. At this time, the chassis is rotated so that the latching tooth is latched into the slot, thereby completing the installation of the chassis and the first bracket.
[0017] The technical solution of the present application can realize quick assembly and quick disassembly of the first bracket and the chassis, thereby improving the assembly efficiency of the cooking equipment.
[0018] In some technical solutions of the present application, optionally, the number of the second brackets is at least two, and the at least two second brackets are spaced apart along the circumference of the chassis, and a bottom coil is wound around each second bracket.
[0019] In this technical solution, the second bracket is used to wind the bottom coil, and the number of the second brackets is relative to the number of the bottom coils. When the number of the bottom coils is at least two, the number of the second brackets is also at least two. Exemplarily, the number of the second brackets can be greater than the number of the bottom coils. For example, when the number of the bottom coils is three, the number of the second brackets can be four.
[0020] The second bracket is arranged on the chassis, and a plurality of second brackets are arranged at intervals along the circumference of the chassis, so that after the winding of the bottom coil is completed, the bottom coil is also arranged at intervals along the circumference of the chassis. When the cooking device is working, the inner pot is placed in the accommodating cavity of the first bracket, and the position of the inner pot is fixed at this time. Since the chassis is connected to the first bracket, it can be ensured that the bottom coil is arranged at intervals along the circumference of the bottom wall of the inner pot at this time, so that the bottom coil can cover a larger area of the bottom wall, and while ensuring the heating efficiency, a weak magnetic field area is formed between two adjacent bottom coils, thereby forming a weak heat area and a strong heat area on the bottom wall of the inner pot, and promoting the heat to flow from the strong heat area to the weak heat area, forming heat convection, and this heat convection can avoid excessive heat concentration, so that the rice water inside the cooking device is heated more evenly, and the cooked rice is more evenly soft and hard, and the surface is smoother, thereby improving the heating effect.
[0021] In some technical solutions of the present application, optionally, the first bracket includes: a first bracket segment and a second bracket segment, the first bracket segment is located on the side of the first bracket, the second bracket segment is located at the bottom of the first bracket, the first bracket segment and the second bracket segment are enclosed to form a accommodating cavity, and the second bracket segment is located between the accommodating cavity and the second bracket.
[0022] In this technical solution, in the first bracket, the upper part is set as the first bracket segment, and the lower part is set as the second bracket segment. The second bracket segment is bent compared to the first bracket segment, so that the second bracket segment can support the bottom of the pot body.
[0023] The second bracket section extends to the top of the second bracket, so that the second bracket section can separate the pot body and the second bracket, avoiding the pot body from directly contacting the side coil. By providing the second bracket section, the heat preservation effect can be improved.
[0024] In some technical solutions, optionally, a positioning portion is provided on one of the first bracket and the second bracket, and a positioning hole is provided on the other bracket, and the positioning portion is inserted into the positioning hole.
[0025] When installing the second bracket to the first bracket, the positioning part is inserted into the positioning hole. When the positioning part and the positioning hole are relatively matched, the positioning part can position the second bracket to prevent the second bracket from shaking relative to the first bracket, thereby ensuring the installation stability of the first bracket and the second bracket.
[0026] In some technical solutions of the present application, optionally, the second bracket includes: a main body; a wire pressing part; and a winding shaft, wherein the winding shaft is arranged between the main body and the wire pressing part and connected to the main body and the wire pressing part.
[0027] In this technical solution, the second bracket includes a body and a wire pressing part, wherein a winding shaft is provided on the body, and when the bottom coil is wound, the wire is wound around the winding shaft as the rotation axis to form the bottom coil. The wire pressing part is connected to the body through the winding shaft, so that a space for winding is formed between the wire pressing part and the body. The present application can reduce the difficulty of winding by designing the second bracket.
[0028] In some technical solutions of the present application, optionally, the main body is provided with a wire threading hole and a wire fixing portion; the wire pressing portion is provided with a heat dissipation hole; wherein, multiple bottom coils are connected in series in sequence, and the wire output end of a bottom coil passes through the wire threading hole from one side of the main body to the other side of the main body, and is connected to the wire input end of another bottom coil after passing through the wire fixing portion.
[0029] In this technical solution, a threading hole and a wire fixing portion are also provided on the main body, and a plurality of bottom coils are sequentially connected in series. After winding one bottom coil, the wire end of the bottom coil passes through the threading hole on the main body, is threaded from one side of the main body to the other side of the main body, and after being fixed by the wire fixing portion, is routed to the next second bracket, and the next bottom coil is wound.
[0030] For example, multiple bottom coils can be wound sequentially through a complete long wire.
[0031] Exemplarily, in two adjacent bottom coils, the line-in terminal of one bottom coil is connected to the line-out terminal of the other bottom coil through a connector such as a connecting terminal.
[0032] The wire pressing part is provided with heat dissipation holes, which increase the contact area between the bottom coil and the air and improve the heat dissipation capacity.
[0033] The technical solution of the present application, by providing a wire threading hole to allow the outlet end of a bottom coil to pass through the back of the main body, and fixing the wiring between the two bottom coils through the wire fixing part, can effectively avoid the problem of wire sheath damage caused by overlapping and squeezing between the connecting wire and the coil, prevent short circuit and other faults, and at the same time effectively improve the stability of the connecting wire during transportation, reduce the possibility of decoupling due to transportation vibration, and improve the reliability of the cooking equipment.
[0034] In some technical solutions of the present application, optionally, the bracket assembly further includes: a magnetic member, and the magnetic member is arranged on the wire pressing part.
[0035] In this technical solution, the bracket assembly also includes a magnetic component. Exemplarily, the magnetic component can be a magnetic component made of soft ferrite or a magnetic component made of magnetic powder core material.
[0036] Exemplarily, the magnetic member is arranged on a side of the pressing line portion facing away from the inner pot.
[0037] Exemplarily, the magnetic member is connected to the wire pressing portion by bonding.
[0038] Exemplarily, the magnetic member is snap-connected to the wire pressing portion via a snap buckle.
[0039] Exemplarily, the magnetic member is fixedly connected to the wire pressing portion via a plastic bracket.
[0040] By providing a magnetic component, the magnetic field of the bottom coil can be converged to a certain extent, thereby reducing the occurrence of magnetic leakage.
[0041] In some technical solutions of the present application, optionally, the main body and the chassis are an integrated structure.
[0042] In this technical solution, the body of the second bracket is integrally formed with the chassis, so when winding the bottom coil, multiple coils can be wound directly on one coil bracket without winding them separately and then assembling and fixing them, thereby reducing the assembly steps and improving assembly efficiency.
[0043] The second aspect of the present application provides a cooking device, including a bracket assembly as provided in any of the above technical solutions. Therefore, the cooking device also includes all the beneficial effects of the bracket assembly provided in any of the above technical solutions. To avoid repetition, they will not be repeated here.
[0044] In some technical solutions of the present application, optionally, the cooking device also includes: an inner pot, the inner pot is accommodated in the first bracket, and the inner pot includes a bottom wall and a side wall; a side coil, the side coil is wound around the first bracket, and the side coil is wound along the bottom wall toward the side wall; and a bottom coil, the bottom coil is wound around the second bracket, and the bottom coil is arranged toward the bottom wall.
[0045] In this technical solution, the cooking equipment includes, but is not limited to, electric rice cookers, electric soup cookers, and electric pressure cookers, and the cooking equipment includes an inner pot for holding food. The cooking equipment also includes a bottom coil and a side coil, which can generate a continuously alternating electromagnetic field after being energized. This continuously alternating electromagnetic field continuously cuts the inner pot, and can generate eddy currents on the inner pot. When the eddy currents flow through the metal pot, Joule heat is generated, thereby heating and cooking the food in the pot, such as rice and water.
[0046] The bottom coil can generate eddy currents on the bottom wall of the inner pot, thereby generating Joule heat on the bottom wall. The side coil can generate eddy currents on the side wall of the inner pot, thereby generating Joule heat on the side wall. By separately arranging the side coils and the bottom coils, the cooking device can heat from the side and the bottom at the same time, making the heat distribution more uniform and improving the cooking effect.
[0047] In some technical solutions of the present application, optionally, the number of the bottom coils is at least two, the at least two bottom coils are distributed at intervals along the circumference of the bottom wall, and at the same time, the polarity of the magnetic field generated by the at least two bottom coils is the same.
[0048] In this technical solution, at the same time, the polarity of the magnetic field generated by the multiple bottom coils is the same. According to the principle of Lorentz's law that like attracts like and opposites repel each other, the magnetic fields of each two adjacent bottom coils in the multiple bottom coils repel each other, and the mutually repelling magnetic fields will cancel each other out to a certain extent, thereby forming a weak magnetic field area in a small range between two adjacent bottom coils. This weak magnetic field area will form a relatively weak heat area on the bottom wall of the inner pot. During the cooking process, due to the heat transfer effect of the inner pot itself, the heat energy of the strong heat area will be transferred to the weak heat area, thereby forming heat convection. This heat convection can avoid excessive heat concentration. At the same time, since such a weak heat area is only formed in a small range between two adjacent bottom coils, it will not have a significant impact on the heating efficiency.
[0049] The technical solution of the present application is to set up multiple bottom coils at the bottom that can simultaneously generate magnetic fields with the same magnetic properties, thereby forming a small-scale weak magnetic field area between two adjacent bottom coils. This will form a strong heat area and a small-scale weak heat area at the bottom of the pot, prompting heat to flow from the strong heat area to the weak heat area. It can avoid the problem of excessive heat concentration in some areas without significantly affecting the cooking efficiency, so that the rice water inside the cooking equipment can be heated more evenly, the cooked rice can be more evenly soft and hard, and the surface can be smoother, thereby improving the heating effect.
[0050] In some technical solutions of the present application, optionally, a projection of the side coil on a first plane overlaps at least partially with a bottom coil; wherein the first plane is the plane where the bottom coil is located.
[0051] In this technical solution, due to the principle of heat rising, the heating power of the bottom coil of the cooking device is generally higher than the heating power of the side wall coil, so that the bottom coil at the bottom is used for main heating, and the side coil at the side is used for auxiliary heating. This causes the heat of the bottom wall of the cooking device to be higher than the heat of the side wall, which causes the degree of gelatinization of the rice close to the bottom wall of the inner pot to be higher than that of the rice in other positions.
[0052] In view of the above problems, the technical solution of the present application designs that the bottom coil of the bottom partially extends out of the side wall of the inner pot in the axial direction of the inner pot. Specifically, the plane where the bottom coil is located is defined as the first plane. For example, any three points can be selected on the bottom coil, and the planes corresponding to these three points are the above first plane.
[0053] The side coil is projected on the first plane in a direction perpendicular to the first plane, and the projection of the side coil on the first plane is overlapped with at least part of the bottom coil, that is, at least part of the bottom coil overlaps with the side coil in the height direction of the inner pot. The magnetic field generated by the part of the bottom coil overlapping with the side coil will also act on the side wall of the inner pot, so that while the side wall of the inner pot is heated in the lateral direction by the side coil, the side wall of the inner pot is supplementarily heated by the bottom coil at the bottom, so that the magnetic fields generated by the bottom coil and the side coil will both act on the side wall of the inner pot, thereby improving the heating effect on the side wall of the inner pot, so that the side wall and the bottom wall of the inner pot can be heated more evenly, so that the gelatinization degree of rice at different positions when cooking rice is close, and the cooking effect is improved.

[0068] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0070] Refer to the following Figures 1 to 9 The present invention describes a support assembly and a cooking device provided according to some embodiments of the present application.
[0071] In some embodiments of the present application, a bracket assembly is provided. Figure 1 , Figure 2A , Figure 2B and Figure 3 The schematic diagram of the structure of the bracket assembly of some embodiments of the present application is shown as follows: Figure 1 , Figure 2A , Figure 2B and Figure 3 As shown, the cooking device 200 includes: a first bracket 102, the first bracket 102 includes a accommodating cavity 1022, the accommodating cavity 1022 is used to accommodate the inner pot 202, and the first bracket 102 is used to wind the side coil 204; a chassis 104, the chassis 104 is detachably connected to the first bracket 102; a second bracket 106, the second bracket 106 is connected to the chassis 104, the first bracket 102 and the second bracket 106 are respectively located on both sides of the chassis 104, and the second bracket 106 is used to wind the bottom coil 206.
[0072] In this embodiment, the cooking device 200 includes a support assembly 100, which is illustratively a coil disc support for winding a bottom coil 206 and a side coil 204. The support assembly 100 includes a first support 102, a bottom plate 104, and a second support 106, and the first support 102 and the bottom plate 104 are separately arranged. Among them, the first support 102 includes a receiving cavity 1022. When the cooking device 200 performs cooking, the inner pot 202 is placed at a specific position in the receiving cavity 1022, and the side coil 204 is wound around the first support 102, so that when the inner pot 202 is placed in the receiving cavity 1022, the side coil 204 is located outside the side wall 2022 of the inner pot 202.
[0073] The second bracket 106 is connected to the first bracket 102 through the bottom plate 104, wherein the second bracket 106 and the first bracket 102 are respectively located on both sides of the bottom plate 104. The bottom coil 206 is wound around the second bracket 106, and the bottom plate 104 is located at the bottom of the first bracket 102, so that when the inner pot 202 is placed in the accommodating cavity 1022, the bottom coil 206 can be arranged toward the bottom wall 2024 of the inner pot 202.
[0074] By arranging the first bracket 102 and the second bracket 106 separately, when producing or assembling the cooking device 200, the side coil 204 can be independently wound on the first bracket 102, and the bottom coil 206 can be independently wound on the second bracket 106 on the chassis 104. After the winding is completed, the chassis 104 with the second bracket 106 is assembled with the first bracket 102.
[0075] For example, the number of the second brackets 106 is the same as the number of the bottom coils 206. When the cooking device 200 is produced and assembled, the bottom coils 206 are wound one by one on the plurality of second brackets 106 on the chassis 104. At the same time, the side coils 204 are wound separately on the first bracket 102. After the winding of the side coils 204 on the first bracket 102 and the bottom coils 206 on the second bracket 106 is completed, the first bracket 102 and the chassis 104 are assembled, and the bottom coils 206 and the side coils 204 are wired, thereby realizing modular production.
[0076] The present application simplifies the assembly process of the cooking device 200 and improves modular production efficiency by using the split design of the first bracket 102 and the second bracket 106.
[0077] In some embodiments of the present application, optionally, as shown in FIG. 2 and Figure 3As shown, a limiting rib 1024 is provided at the bottom of the first bracket 102 , and the limiting rib 1024 includes a slot 1026 ; the chassis 104 is provided with a mounting portion 1042 opposite to the limiting rib 1024 , and the mounting portion 1042 includes a clamping portion 1044 , and the clamping portion 1044 is clamped in the slot 1026 .
[0078] In this embodiment, a limiting rib 1024 is provided at the bottom of the first bracket 102, and the chassis 104 includes a mounting portion 1042 that is opposite to the limiting rib 1024. When the first bracket 102 and the chassis 104 are connected, the limiting rib 1024 cooperates with the mounting portion 1042 to fix the relative position of the first bracket 102 and the chassis 104, so that after assembly, the relative position of the bottom coil 206 and the inner pot 202 can be ensured to be relatively fixed. A clamping groove 1026 is provided on the limiting rib 1024, and a clamping portion 1044 is provided on the mounting portion 1042. When the first bracket 102 and the chassis 104 are assembled and fixed, the first bracket 102 and the chassis 104 are fixed by clamping the clamping portion 1044 into the clamping groove 1026.
[0079] Exemplarily, the limiting rib 1024 is a raised cylindrical structure, and the mounting portion 1042 is a through hole matching the shape of the cylindrical structure. A transverse slot 1026 is provided on the cylindrical structure, and an avoidance portion is provided at the starting position of the transverse slot 1026. A latching tooth is provided on the side wall 2022 of the through hole, and the latching tooth is the above-mentioned latching portion 1044. When assembling the first bracket 102 and the chassis 104, the cylindrical structure is passed through the through hole, and the latching tooth on the through hole enters the slot 1026 through the avoidance portion. At this time, the chassis 104 is rotated so that the latching tooth is latched into the inside of the slot 1026, thereby completing the installation of the chassis 104 and the first bracket 102.
[0080] The embodiment of the present application can realize quick assembly and quick disassembly of the first bracket 102 and the chassis 104 , thereby improving the assembly efficiency of the cooking device 200 .
[0081] In some embodiments of the present application, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the number of the second brackets 106 is at least two, and the at least two second brackets are spaced apart along the circumference of the chassis 104 , and a bottom coil 206 is wound around each second bracket 106 .
[0082] In this embodiment, Figure 3The arrow Y in the figure shows the circumference of the chassis 104. The second brackets 106 are used to wind the bottom coils 206. The number of the second brackets 106 is relative to the number of the bottom coils 206. When the number of the bottom coils 206 is at least two, the number of the second brackets 106 is also at least two. Exemplarily, the number of the second brackets 106 may be greater than the number of the bottom coils 206. For example, when the number of the bottom coils 206 is three, the number of the second brackets 106 may be four.
[0083] The second brackets 106 are disposed on the chassis 104 and are spaced apart along the circumference of the chassis 104 . Therefore, after the bottom coil 206 is wound, the bottom coil 206 is also spaced apart along the circumference of the chassis 104 . When the cooking device 200 is working, the inner pot 202 is placed in the accommodating cavity 1022 of the first bracket 102. At this time, the position of the inner pot 202 is fixed. Since the bottom plate 104 is connected to the first bracket 102, it can ensure that the bottom coil 206 is arranged at intervals along the circumference of the bottom wall 2024 of the inner pot 202, so that the bottom coil 206 can cover a larger area of the bottom wall 2024. While ensuring the heating efficiency, a weak magnetic field area is formed between two adjacent bottom coils 206, thereby forming a weak heat area and a strong heat area on the bottom wall 2024 of the inner pot 202, which promotes heat to flow from the strong heat area to the weak heat area, forming heat convection. This heat convection can avoid excessive heat concentration, so that the rice water inside the cooking device 200 is heated more evenly, and the cooked rice is more evenly soft and hard, and the surface is smoother, thereby improving the heating effect.
[0084] In some embodiments of the present application, optionally, Figure 2B As shown, the first bracket 102 includes: a first bracket segment 112 and a second bracket segment 113, the first bracket segment is located at the side of the first bracket 102, the second bracket segment is located at the bottom of the first bracket 102, the first bracket segment 112 and the second bracket segment 113 enclose a receiving cavity 1022, and the second bracket segment is located between the receiving cavity 1022 and the second bracket 106.
[0085] In this embodiment, in the first bracket 102, the upper part is set as the first bracket segment 112, and the lower part is set as the second bracket segment 113. The second bracket segment 113 is bent compared to the first bracket segment 112, so that the second bracket segment 113 can support the bottom of the pot body.
[0086] The second bracket section 113 extends to the top of the second bracket, so that the second bracket section 113 can separate the pot body and the second bracket, avoiding the pot body from directly contacting the side coil. By providing the second bracket section 113, the heat preservation effect can be improved.
[0087] In some embodiments, optionally, a positioning portion is provided on one of the first bracket 102 and the second bracket, and a positioning hole is provided on the other bracket, and the positioning portion is inserted into the positioning hole.
[0088] When installing the second bracket to the first bracket 102, the positioning part is inserted into the positioning hole. When the positioning part and the positioning hole are relatively matched, the positioning part can position the second bracket to prevent the second bracket from shaking relative to the first bracket 102, thereby ensuring the installation stability of the first bracket 102 and the second bracket.
[0089] In some technical solutions of the present application, optionally, Figure 4 and Figure 5 Schematic diagrams showing the structure of the second bracket 106 in some embodiments of the present application are shown. Figure 4 and Figure 5 As shown, the second bracket 106 includes: a body 1061 ; a wire pressing portion 1065 ; and a winding shaft 1062 . The winding shaft 1062 is disposed between the body 1061 and the wire pressing portion 1065 , and is connected to the body 1061 and the wire pressing portion 1065 .
[0090] In this technical solution, the second bracket 106 includes a body 1061 and a wire pressing portion 1065, wherein a winding shaft 1062 is provided on the body 1061. When the bottom coil is wound, the wire is wound around the winding shaft 1062 as the rotation axis to form the bottom coil. The wire pressing portion 1065 is connected to the body 1061 through the winding shaft 1062, so that a space for winding is formed between the wire pressing portion 1065 and the body 1061. The present application can reduce the difficulty of winding by designing the second bracket 106.
[0091] In some embodiments of the present application, optionally, Figure 4 and Figure 5 As shown, the main body 1061 is provided with a threading hole 1063 and a wire fixing portion 1064; the wire pressing portion 1065 is provided with a heat dissipation hole 1066; wherein, multiple bottom coils are connected in series in sequence, and the outlet end of a bottom coil passes from one side of the main body 1061 through the threading hole 1063 to the other side of the main body 1061, and is connected to the inlet end of another bottom coil after passing through the wire fixing portion 1064.
[0092] In this embodiment, the second bracket 106 includes a body 1061 and a wire pressing portion 1065, wherein a winding shaft 1062 is provided on the body 1061. When the bottom coil 206 is wound, the wire is wound around the winding shaft 1062 as the rotation axis to form the bottom coil 206. The body 1061 is also provided with a threading hole 1063 and a wire fixing portion 1064. A plurality of bottom coils 206 are sequentially connected in series. After winding one bottom coil 206, the outlet end of the bottom coil 206 passes through the threading hole 1063 on the body 1061, is threaded from one side of the body 1061 to the other side of the body 1061, and after being fixed by the wire fixing portion 1064, is routed to the next second bracket 106, and the next bottom coil 206 is wound.
[0093] For example, a plurality of bottom coils 206 may be wound sequentially through a complete long wire.
[0094] Exemplarily, among two adjacent bottom coils 206 , the line-in terminal of one bottom coil 206 is connected to the line-out terminal of the other bottom coil 206 via a connector such as a connection terminal.
[0095] The wire pressing portion 1065 is provided with heat dissipation holes 1066 , and the contact area between the bottom coil 206 and the air is increased through the heat dissipation holes 1066 , thereby improving the heat dissipation capability.
[0096] In the embodiment of the present application, a wire threading hole 1063 is provided to allow the wire end of a bottom coil 206 to be passed through the back side of the main body 1061, and the wiring between the two bottom coils 206 is fixed by the wire fixing portion 1064. This can effectively avoid the problem of wire sheath damage caused by overlapping and squeezing between the connecting wire and the coil, prevent short circuit and other faults, and effectively improve the stability of the connecting wire during transportation, reduce the possibility of disconnection due to transportation vibration, and improve the reliability of the cooking device 200.
[0097] In some embodiments of the present application, optionally, Figure 6 The schematic diagram of the structure of the bracket assembly of some embodiments of the present application is shown as follows: Figure 6 As shown, the bracket assembly 100 further includes: a magnetic member 108 , and the magnetic member 108 is disposed on the wire pressing portion 1065 .
[0098] In this embodiment, the support assembly 100 further includes a magnetic member 108. Exemplarily, the magnetic member 108 may be a magnetic member 108 made of soft ferrite or a magnetic member 108 made of magnetic powder core material.
[0099] Exemplarily, the magnetic member 108 is disposed on a side of the pressing line portion 1065 facing away from the inner pot 202 .
[0100] Exemplarily, the magnetic member 108 is connected to the wire pressing portion 1065 by bonding.
[0101] Exemplarily, the magnetic member 108 is snap-connected to the wire pressing portion 1065 via a snap buckle.
[0102] Exemplarily, the magnetic member 108 is fixedly connected to the wire pressing portion 1065 via a plastic bracket.
[0103] By providing the magnetic member 108 , the magnetic field of the bottom coil 206 can be converged to a certain extent, thereby reducing the occurrence of magnetic leakage.
[0104] In some embodiments of the present application, optionally, the body 1061 and the chassis 104 are an integrated structure.
[0105] In this embodiment, the main body 1061 of the second bracket 106 is integrally formed with the chassis 104. Therefore, when winding the bottom coil 206, multiple coils can be directly wound on one coil bracket without winding them separately and then assembling and fixing them. This can reduce the assembly steps and improve assembly efficiency.
[0106] The second aspect of the present application provides a cooking device 200, including a bracket assembly 100 as provided in any of the above embodiments. Therefore, the cooking device 200 also includes all the beneficial effects of the bracket assembly 100 provided in any of the above embodiments, which will not be described again here to avoid repetition.
[0107] In some embodiments of the present application, optionally, Figure 7 , Figure 8 and Fig. 9 The schematic diagram of the structure of the cooking device of some embodiments of the present application is shown as follows: Figure 7 , Figure 8 and Fig. 9 As shown, the cooking device 200 also includes: an inner pot 202, which is accommodated in the first bracket 102, and the inner pot 202 includes a bottom wall 2024 and a side wall 2022; a side coil 204, which is wound around the first bracket 102, and the side coil 204 is wound along the bottom wall 2024 toward the side wall 2022; and a bottom coil 206, which is wound around the second bracket 106, and the bottom coil 206 is arranged toward the bottom wall 2024.
[0108] In this embodiment, the cooking device 200 includes, but is not limited to, an electric rice cooker, an electric soup cooker, and an electric pressure cooker, and the cooking device 200 includes an inner pot 202, and the inner pot 202 is used to hold food. The cooking device 200 also includes a bottom coil 206 and a side coil 204, which can generate a continuously alternating electromagnetic field after being energized, and the continuously alternating electromagnetic field continuously cuts the inner pot 202, and can generate eddy currents on the inner pot 202, and when the eddy currents flow through the metal pot, Joule heat is generated, thereby achieving heating and cooking of food in the pot, such as rice and water.
[0109] The bottom coil 206 can generate eddy currents on the bottom wall 2024 of the inner pot 202, thereby generating Joule heat on the bottom wall 2024. The side coil 204 can generate eddy currents on the side wall 2022 of the inner pot 202, thereby generating Joule heat on the side wall 2022. By separately arranging the side coil 204 and the bottom coil 206, the cooking device 200 can heat from the side and the bottom at the same time, making the heat distribution more uniform and improving the cooking effect.
[0110] In some embodiments of the present application, optionally, the number of the bottom coils 206 is at least two, the at least two bottom coils 206 are distributed at intervals along the circumference of the bottom wall 2024, and at the same time, the polarity of the magnetic field generated by the at least two bottom coils 206 is the same.
[0111] In this embodiment, at the same time, the polarity of the magnetic field generated by the multiple bottom coils 206 is the same. According to the principle of Lorentz's law that like attracts like and opposites repel each other, the magnetic fields of each two adjacent bottom coils 206 in the multiple bottom coils 206 repel each other, and the mutually repelling magnetic fields will cancel each other out to a certain extent, thereby forming a weak magnetic field area in a small range between two adjacent bottom coils 206, and this weak magnetic field area will form a relatively weak heat area on the bottom wall 2024 of the inner pot 202. During the cooking process, due to the heat transfer effect of the inner pot 202 itself, the heat energy of the strong heat area will be transferred to the weak heat area, thereby forming heat convection, which can avoid excessive heat concentration. At the same time, since such a weak heat area is only formed in a small range between two adjacent bottom coils 206, it will not have a significant impact on the heating efficiency.
[0112] Exemplarily, the bottom coil 206 is electrically connected to the excitation circuit 208. The excitation circuit 208 can cause the bottom coil 206 to generate a magnetic field by passing a current in a certain direction into the bottom coil 206. The magnetic field generated by the bottom coil 206 can generate a heating current on the bottom wall of the inner pot, thereby causing the bottom wall of the inner pot to heat up.
[0113] At least two bottom coils 206 are defined, including a first sub-coil 2062 and a second sub-coil 2064. Since the polarity of the magnetic field generated by different sub-coils is related to the winding direction and the current direction, in order to achieve the same magnetic field polarity for the first sub-coil 2062 and the second sub-coil 2064, the connection method between the input and output terminals of the two sub-coils and the positive and negative poles of the excitation circuit 208 can be controlled based on the winding direction of the first sub-coil 2062 and the second sub-coil 2064.
[0114] Exemplarily, the above-mentioned winding direction includes a clockwise direction and a counterclockwise direction.
[0115] Exemplarily, assuming that the winding directions of the first sub-coil 2062 and the second sub-coil 2064 are the same, the connection mode between the input and output terminals of the first sub-coil 2062 and the positive output and negative output terminals of the excitation circuit 208 is set to be the same as the connection mode between the input and output terminals of the second sub-coil 2064 and the positive output and negative output terminals of the excitation circuit 208, and the current directions in the first sub-coil 2062 and the second sub-coil 2064 are also kept the same. Since the winding directions and current directions of the two different coils are the same, the magnetic field polarities that can be generated by the two coils can be the same.
[0116] Exemplarily, assuming that the winding directions of the first sub-coil 2062 and the second sub-coil 2064 are opposite, the connection mode of the input and output terminals of the first sub-coil 2062 and the positive output and negative output terminals of the excitation circuit 208 is set to be opposite to the connection mode of the input and output terminals of the second sub-coil 2064 and the positive output and negative output terminals of the excitation circuit 208, and the current directions in the first sub-coil 2062 and the second sub-coil 2064 are also kept opposite. Since the windings of the two different coils are opposite and the currents are opposite and the same, the magnetic field polarity that can be generated by the two coils in this case can also be the same.
[0117] The embodiment of the present application sets a plurality of bottom coils 206 at the bottom that can simultaneously generate magnetic fields with the same magnetic properties, thereby forming a small-scale weak magnetic field area between two adjacent bottom coils 206. This will form a strong heat area and a small-scale weak heat area at the bottom of the pot, prompting heat to flow from the strong heat area to the weak heat area. It can avoid the problem of excessive heat concentration in some areas without significantly affecting the cooking efficiency, so that the rice water inside the cooking device 200 is heated more evenly, the cooked rice is more evenly soft and hard, and the surface is smoother, thereby improving the heating effect.
[0118] In some embodiments of the present application, optionally, a projection of the side coil 204 on the first plane 210 overlaps with at least a portion of the bottom coil 206 ; wherein the first plane 210 is the plane where the bottom coil 206 is located.
[0119] In this embodiment, due to the principle of heat rising, the heating power of the bottom coil 206 of the cooking device 200 is generally higher than the heating power of the side wall 2022 coil, so that the bottom coil 206 at the bottom is used for primary heating, and the side coil 204 at the side is used for auxiliary heating. This causes the heat of the bottom wall 2024 of the cooking device 200 to be higher than the heat of the side, which causes the degree of gelatinization of the rice close to the bottom wall 2024 of the inner pot 202 to be higher than that of the rice at other positions.
[0120] In view of the above problems, the embodiment of the present application designs the bottom coil 206 to extend partially out of the side wall 2022 of the inner pot 202 in the axial direction of the inner pot 202. Specifically, the plane where the bottom coil 206 is located is defined as the first plane 210. For example, any three points can be selected on the bottom coil 206, and the planes corresponding to these three points are the first plane 210.
[0121] A projection of the side coil 204 on the first plane 210 is made along a direction perpendicular to the first plane 210, and the projection of the side coil 204 on the first plane 210 is made to overlap with at least a portion of the bottom coil 206, that is, in the height direction of the inner pot 202, at least a portion of the bottom coil 206 overlaps with the side coil 204. The magnetic field generated by the bottom coil 206 overlapping with the side coil 204 will also act on the side wall 2022 of the inner pot 202. Therefore, while the side wall 2022 of the inner pot 202 is heated in the lateral direction by the side coil 204, the side wall 202 of the inner pot 202 can be supplementarily heated by the bottom coil 206 at the bottom, so that the magnetic fields generated by the bottom coil 206 and the side coil 204 will both act on the side wall 2022 of the inner pot 202, thereby improving the heating effect on the side wall 2022 of the inner pot 202, so that the side wall 2022 and the bottom wall 2024 of the inner pot 202 can obtain a more even heating effect, so that the gelatinization degree of rice at different positions when cooking rice is close, thereby improving the cooking effect.
