The base 26 can also simultaneously provide the side wall of the receiving cavity 21, so that the base 26 is used to enclose the receiving cavity 21.

[0238] As Figures 1 to 6As shown, the coil assembly 660 further includes a disc-shaped winding 182 for forming the resonant inductor of the electromagnetic heating resonant circuit to generate an alternating magnetic field required for electromagnetic heating after being energized. The circuit board assembly 22 is used to supply power to the disc-shaped winding 182. The circuit board assembly 22 is provided with, for example, a resonant capacitor used in conjunction with the disc-shaped winding 182, a switching module (such as a power switching transistor IGBT), a control module, a power supply module, etc. The coil assembly 660 is disposed at the bottom of the accommodating cavity 21, and the cooking container 30 is detachably disposed within the magnetic induction region (i.e., the electromagnetic heating region) of the coil assembly 260, for example, at least below. The cooking container 30 has a cooking container central axis P3. The cooking container 30 is generally in the shape of a rotating body with the cooking container central axis P3 as the axis.

[0239] The coil assembly 660 includes a coil component 670. The coil component 670 includes at least one disc-shaped winding 182 for generating an alternating magnetic field after being energized. The coil component 670 has a coil component central axis PA. The coil component 670 is configured such that the magnetic field intensity of the alternating magnetic field is non-uniformly distributed along the circumferential direction of the coil component 670. Among them, the electromagnetic heating cooking appliance 600 is configured such that the cooking container 30 is detachably disposed at least above the coil component 670. When the cooking container 30 is located at least above the coil component 670, the cooking container central axis P3 and the coil component central axis PA are substantially coincident, and at least a part of the coil component 670 can rotate relative to the cooking container 30 around the coil component central axis PA. As an alternative embodiment, in specific implementation, the cooking container 30 can also be selectively rotated relative to at least a part of the coil component 670 around the cooking container central axis P3. Thus, one of the cooking container 30 and the alternating magnetic field generated by the coil component 670 can rotate relative to the other around the coil component central axis PA, so that the heated part of the cooking container 30 rotates along the circumferential direction of the cooking container 30 on the cooking container 30.

[0240] In the present application, the two central axes being substantially coincident means that the distance between the two central axes ≤ 3 mm and the included angle between the two central axes ≤ 5°. That is, the two central axes are substantially parallel and close to each other.

[0241] It can be understood that both the cooking container central axis P3 and the coil component central axis PA extend along the height direction of the cooking appliance 100.

[0242] In an embodiment not shown in the present application, the wire coil device 660 is configured to be disposed on the side of the cooking container 30 (for example, the wire coil device 660 is configured to include a sleeve that can be sleeved on the outer periphery of the cooking container 30). That is, in the present application, the cooking container 30 and the wire coil device 660 are detachably disposed on one side within the magnetic induction region of the wire coil device 660 (that is, the disk-shaped winding 182 and / or the magnetic field generated thereby is located at least on the lower side or at least on the outer side of the cooking container 30), and the central axis P3 of the cooking container is made to substantially coincide with the central axis PA of the wire coil assembly.

[0243] As some preferred embodiments of the present application, as Figures 3 to 5 shown, the wire coil assembly 670 includes a plurality of disk-shaped windings 182, and the plurality of disk-shaped windings 182 are spaced apart in the circumferential direction of the wire coil assembly 670 such that all the disk-shaped windings 182 do not fill the circular ring region with the central axis PA of the wire coil assembly as the axis. Alternatively, the wire coil assembly 670 includes only one disk-shaped winding 182, and the winding center of the disk-shaped winding 182 deviates from the central axis PA of the wire coil assembly. The disk-shaped winding 182 is not concentric with the wire coil assembly 670. Thus, along the circumferential direction of the wire coil assembly 670, the magnetic field line density is large and the magnetic field strength is strong in the region where the disk-shaped winding 182 is distributed, and the magnetic field line density is small and the magnetic field strength is weak in the region where the disk-shaped winding 182 is not distributed. That is, the non-uniform distribution of the magnetic field strength is achieved by making the disk-shaped winding 182 non-uniformly distributed in the circumferential direction of the wire coil assembly 670.

[0244] The gap between two adjacent disk-shaped windings 182 cannot be too small, otherwise electromagnetic self-interference will occur, resulting in adverse phenomena such as high back pressure, low inductance, low heating power, large stored current, and messy heating waveforms.

[0245] The driving device 50 disposed on the base 26 is configured to drive one of the cooking container 30 and the alternating magnetic field generated by the wire coil assembly 670 to rotate relative to the other around the central axis PA of the wire coil assembly. In the illustrated embodiment, the cooking appliance 600 is configured such that the cooking container 30 is rotatable relative to the wire coil assembly 670 around the central axis P3 of the cooking container. That is, the driving device 50 is configured to drive the cooking container 30 to rotate around the central axis PA of the wire coil assembly relative to the wire coil assembly 670.

[0246] It should be noted that in the present application, the number of disk-shaped windings 182 included in the wire coil assembly 670 is not specifically limited. In specific implementation, the number of disk-shaped windings 182 included in the wire coil assembly 670 can be selectively one, two, three, four, five, six, seven, eight, nine, or ten or more. In specific implementation, as Figures 3 to 6As shown, preferably, the number of the disk-shaped windings 182 is three, and the three disk-shaped windings 182 are arranged at intervals along the circumferential direction of the wire spool assembly 670. Further preferably, the three disk-shaped windings 182 are equally spaced along the circumferential direction of the wire spool assembly 670.

[0247] In the present application, the wire spool assembly 670 is configured such that an alternating magnetic field has N strong magnetic regions and N weak magnetic regions alternately distributed along the circumferential direction of the wire spool assembly 670, wherein the magnetic field intensity of the strong magnetic regions is greater than that of the weak magnetic regions. In the illustrated embodiment, the portions of the wire spool assembly 670 corresponding to the positions where the disk-shaped windings 182 are provided are strong magnetic regions, and the portions corresponding to the gaps between two disk-shaped windings 182 are weak magnetic regions. The N strong magnetic regions are equally spaced along the circumferential direction of the wire spool assembly 670, and the N weak magnetic regions are equally spaced along the circumferential direction of the wire spool assembly 670. Among them, the electromagnetic heating cooking appliance 600 is configured such that when the cooking container 30 is at least above the wire spool assembly 670, at least a part of the wire spool assembly 670 and the cooking container 30 can rotate relative to each other by ±180 / N degrees. It can be understood that when the wire spool assembly 670 rotates relative to the cooking container 30 by ±180 / N degrees, the strong magnetic regions cover the entire cooking container 30, that is, the cooking container 30 is heated evenly. Of course, the wire spool assembly 670 can rotate relative to the cooking container 30 by a larger angle (preferably an angle that is an integer multiple of ±180 / N degrees, and there is no limit to the upper limit of the rotation angle), but it needs to rotate at least ±180 / N degrees to ensure that the cooking container 30 is heated evenly.

[0248] It should be noted that N is any integer greater than or equal to 1; in specific implementation, N can optionally be any value among 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. It should be further pointed out that N is not limited to the values listed above, and it can also be any value greater than 10. In specific implementation, N can also be 11, 12, 13, etc. In the illustrated embodiment, the wire spool assembly 670 is configured such that an alternating magnetic field has 3 strong magnetic regions and 3 weak magnetic regions alternately distributed along the circumferential direction of the wire spool assembly 670.

[0249] According to the present application, by making the wire spool assembly 670 include at least one disk-shaped winding 182 and making the cooking container 30 rotatable relative to the wire spool assembly 670, the effect of rotational heating of the point heat source of the electromagnetic heating cooking appliance 600 can be achieved, and at the same time, the complex and changeable convection tumbling form and tumbling effect inside the cooking container 30 can be realized, so that the ingredients are heated more evenly, achieving a better cooking effect, and thus improving the user experience. Especially when the wire spool assembly 670 includes multiple disk-shaped windings 182, the effect of rotational heating of multiple point heat sources of the electromagnetic heating cooking appliance 600 can be achieved, thereby making the ingredients heated more evenly and achieving a better cooking effect.

[0250] As some preferred embodiments of the present application, the electromagnetic heating cooking appliance 600 is configured such that when the cooking container 30 is placed at least above the coil assembly 670, the distance between the disc-shaped winding 182 and the cooking container 30 is any value between 3 mm and 30 mm. In specific implementation, preferably, the distance between the disc-shaped winding 182 and the cooking container 30 is between 6 mm and 10 mm.

[0251] According to the present application, the distance between the disc-shaped winding 182 and the cooking container 30 is between 3 mm and 30 mm to solve problems such as the small area of the magnetic field generated by the disc-shaped winding 182 covering the cooking container 30 and insufficient heating power due to too large a distance; at the same time, it can also solve problems such as the large heat generation of the disc-shaped winding 182 and increased energy consumption due to too small a distance between the disc-shaped winding 182 and the cooking container 30.

[0252] As Figure 1 and Figure 5 shown, the coil assembly 670 includes a coil holder 180, at least one coil support 683, and at least one disc-shaped winding 182. The coil holder 180 is preferably configured in a disc shape. The coil holder 180 has a coil holder central axis P8, and the coil holder central axis P8 is also the coil assembly central axis PA. The coil supports 683 are arranged at intervals along the circumferential direction of the coil holder 180. The disc-shaped windings 182 are wound around the coil supports 683, so that the disc-shaped windings 182 are arranged at intervals along the circumferential direction of the coil holder 180. The winding center of the disc-shaped winding 182 is set on the axis of the coil support 683, and the axis of the coil support 683 deviates from the coil holder central axis P8, so that the disc-shaped winding 182 is not concentric with the coil holder 180. In specific implementation, a plurality of coil supports 683 can be further arranged at equal intervals along the circumferential direction of the coil holder 180 on the coil holder 180. A magnetic conductive member can also be arranged on the coil support 683 to further focus (converge) the magnetic force lines of the magnetic field of the disc-shaped winding 182.

[0253] As Figure 4 and Figure 5 shown, the disc-shaped winding 182 is formed by winding an enameled wire 189, for example. The enameled wire 189 includes a winding portion 182A and two end portions 182B. The winding portion 182A is wound in a disc shape around the winding center to form an effective resonant inductor of the electromagnetic heating resonant circuit. The end portions 182B are the parts of the enameled wire 189 not used to form the effective resonant inductor, and the winding portion 182A is located between the two end portions 182B. At least some of the plurality of disc-shaped windings 182 are connected in series, that is, formed by winding the same enameled wire 189; or, the plurality of disc-shaped windings 182 do not share a wire (enameled wire), that is, each disc-shaped winding is wound by its own enameled wire 189. Preferably, the coil holder 180 is provided with a bundling member 180P for bundling all the end portions 182B.

[0254] Preferably, the axial cross-section of the coil reel 180 is a C-shaped structure. The coil reel 180 has a radially symmetric structure with the central axis P8 of the coil reel as the axis. The disc-shaped winding 182 is disposed, for example, on the outer side of the C-shaped structure, and the cooking container 30 is located, for example, on the inner side of the C-shaped structure, so as to facilitate the connection of the enameled wire 189 to the circuit board assembly 22.

[0255] For example, the two end portions 182B of the enameled wire 189 continue to extend to form a first connection segment 182C and a second connection segment 182D. The circuit board assembly 22 further includes a first power supply wire 24A and a second power supply wire 24B. The first power supply wire 24A and the second power supply wire 24B are connection wires extending from the printed circuit board of the circuit board assembly 22. The first power supply wire 24A is connected to the first connection segment 182C, and the second power supply wire 24B is connected to the second connection segment 182D, thereby connecting the disc-shaped winding 182 to the circuit board assembly 22.

[0256] The first power supply wire 24A and the second power supply wire 24B can be single-strand wires or multi-strand wires. Specifically, the number of wire strands is the same as the number of the first enameled wires 189. That is, when the coil assembly 670 includes M first enameled wires 189, the first power supply wire 24A includes M wires (strands), and the second power supply wire 24B includes M wires (strands). For example, the coil assembly 670 includes one first enameled wire 189, and the three disc-shaped windings 182 are all wound by the one first enameled wire 189. The first power supply wire 24A and the second power supply wire 24B each include only one (strand) wire. Or, the coil assembly 670 includes three first enameled wires 189, and each first enameled wire 189 winds out a disc-shaped winding 182. The first power supply wire 24A and the second power supply wire 24B each include three (strands) wires.

[0257] As Figure 1As shown, the wire coil device 660 includes a temperature sensor assembly 40 for contacting the bottom surface of the cooking container 30. That is, the temperature sensor assembly 40 is disposed below the cooking container 30 and senses the temperature of the cooking container 30 by contacting the bottom surface of the cooking container 30. In this application, the temperature sensor assembly 40 is also referred to as the temperature sensing device 40. In this application, the wire coil device 660 is configured such that the coil holder 180 is connected to the wall of the receiving cavity (for example, the outer peripheral edge of the coil holder 180 is connected to the side wall of the receiving cavity 21), so that at least a part of the temperature sensor assembly 40 can rotate relative to the coil holder 180 around the central axis P8 of the coil holder, so as to drive the cooking container 30 to rotate synchronously relative to the coil holder 180 around the central axis P8 of the coil holder. The driving device 50 is connected to the temperature sensor assembly 40 and is used to drive at least a part of the temperature sensor assembly 40 to rotate relative to the coil holder 180 (that is, the cooker body 20) around the central axis P8 of the coil holder, driving the cooking container 30 to rotate synchronously relative to the coil holder 180 around the central axis P8 of the coil holder.

[0258] As Figure 1 , Figure 2 , Figure 6 and Figure 7 shown, the driving device 50 can be selectively configured to include a driving component 51 and a transmission component 55. The driving component 51 is used to provide a driving force for rotating at least a part of the temperature sensor assembly 40 relative to the coil holder 180, and the transmission component 55 is connected between the driving component 51 and the temperature sensor assembly 40 and is used to transmit the driving force to the temperature sensor assembly 40. That is, the driving component 51 is drivably connected to the temperature sensor assembly 40 through the transmission component 55. Under the drive of the driving component 51, at least a part of the temperature sensor assembly 40 can rotate relative to the coil holder 180 around the central axis PA of the wire coil assembly.

[0259] The driving component 51 is configured as a motor, for example. The motor 51 is a stepping motor, for example, so as to be able to provide power for the forward and reverse rotation of the temperature sensor assembly 40. The motor 51 is electrically connected to the control module of the circuit board assembly 22 and operates under the control of the control module. By controlling the motor 51, the control module can realize the forward and reverse rotation and intermittent rotation of the temperature sensor assembly 40, and the rotation speed and stroke are adjustable. The rotation speed value range of the temperature sensor assembly 40 is, for example, 1 r / min to 350 r / min, preferably 4 r / min to 6 r / min.

[0260] The transmission assembly 55 includes, for example, a first transmission wheel 57 and a second transmission wheel 58, where both the first transmission wheel 57 and the second transmission wheel 58 are configured as gears for meshing transmission. Further, the first transmission wheel 57 is connected to the motor shaft 59 (motor output shaft) of the motor 51, and the second transmission wheel 58 is connected to the temperature sensor assembly 40. When power is supplied to the motor 51, the motor 51 can drive at least a part of the temperature sensor assembly 40 to rotate through the first transmission wheel 57 and the second transmission wheel 58, ultimately causing the cooking container 30 to rotate.

[0261] It should be noted that the first transmission wheel 57 and the second transmission wheel 58 can be selectively configured as one of a gear, a roller, a sprocket, a pulley, a friction wheel, etc. Preferably, both the first transmission wheel 57 and the second transmission wheel 58 are configured as gears.

[0262] As some preferred embodiments of the present application, as Figure 1 and Figure 7 shown, the electromagnetic heating cooking appliance 600 further includes a magnetic shielding cover 52, which is made of a metal material and is used to cover at least a part of the driving device 50 (for example, covering the motor 51) to shield the magnetic field generated by the disc-shaped winding 182. For example, the motor 51 is mounted on the base 26 of the cooking pot body 20 through two bolts 54, and the magnetic shielding cover 52 can be mounted to the base 26 by using the two bolts 54 at the same time, so that the outer shell of the motor 51 is in contact with the magnetic shielding cover 52. The magnetic shielding cover 52 is provided with a through hole 56 for the motor shaft 59 to pass through.

[0263] As some preferred embodiments of the present application, further, the electromagnetic heating cooking appliance 600 further includes a ground wire 53. One end of the ground wire 53 is connected to the outer shell of the magnetic shielding cover 52 and / or the motor 51 (for example, fixed to the magnetic shielding cover 52 through the bolt 54), and the other end of the ground wire 53 is connected to the ground terminal of the electromagnetic heating cooking appliance 600, such as the ground terminal on the circuit board assembly 22 or the ground terminal on the power socket 27. Under the action of the ground wire 53, the outer shell of the motor 51 and the magnetic shielding cover 52 are grounded together, which can also effectively improve the magnetic shielding effect of the magnetic shielding cover 52.

[0264] To achieve a better magnetic shielding effect, the motor shaft 59 can be further selectively made of a non-metallic material. Of course, the motor shaft 59 can also be made of a metal material. In addition, the transmission assembly 55 (the first transmission wheel 57, the second transmission wheel 58, etc.) included in the driving device 50 can also be made of a non-metallic material.

[0265] The structure of the temperature sensor assembly 40 will be introduced in detail below.

[0266] As Figures 8 to 11As shown, in the assembled state, the temperature sensor assembly 40 includes a first end 431 and a second end 432 that are oppositely arranged along the axial direction of the coil rack 180. Among them, the first end 431 is used to contact the bottom surface of the cooking container 30, and the second end 432 is provided with an outlet for leading out the cable of the temperature sensor assembly 40. The axial direction of the temperature sensor assembly 40 is also the axial direction of the coil rack 180, and the radial direction of the temperature sensor assembly 40 is also the radial direction of the coil rack 180.

[0267] Specifically, the temperature sensor assembly 40 includes a housing 43, a temperature-sensing fuse assembly 49, and a wiring assembly 40A.

[0268] The housing 43 includes a housing body 43A and a temperature-sensing cover 43B. The housing body 43A is generally constructed as a rotary body structure, such as a cylindrical shape, and has a housing body central axis P4. The housing body central axis P4 can also be regarded as the central axis of the temperature sensor assembly 40. An installation cavity 437 is formed inside the housing body 43A. At both ends of the housing body 43A along its own axial direction, a first opening 435 and a second opening 436 are respectively provided, and both the first opening 435 and the second opening 436 communicate with the installation cavity 437. The temperature-sensing cover 43B covers the first opening 435 and is used to contact the object to be measured temperature (such as the cooking container 30).

[0269] The temperature-sensing fuse assembly 49 includes at least one electronic component, such as including a thermistor 491. Each electronic component has two electronic component terminals 493. The temperature-sensing fuse assembly 49 is arranged in the installation cavity 437 and close to the first opening 435, so that the temperature-sensing fuse assembly 49 contacts the temperature-sensing cover 43B or is close to the temperature-sensing cover 43B. Thus, when the cooking container 30 contacts the temperature-sensing cover 43B, through the heat conduction of the temperature-sensing cover 43B, the thermistor 491 can sense the temperature of the cooking container 30.

[0270] The wiring assembly 40A is arranged in the installation cavity 437. The wiring assembly 40A includes at least two second cables 484. The second cables 484 are arranged corresponding to the electronic component terminals 493 and are connected to the corresponding electronic component terminals 493. The second cables 484 are exposed from the second opening 436. Thus, the second cables 484 can be connected to the control module of the circuit board assembly 22 to transmit the temperature value sensed by the temperature sensor assembly 40 to the control module. The portions of the multiple second cables 484 outside the installation cavity 437 are integrated into a bundle, for example, to facilitate wiring in the accommodation cavity 21.

[0271] Among them, the temperature sensor assembly 40 is configured such that the temperature-sensing fuse assembly 49 remains in a fixed position relative to the housing body 43A (i.e., the outer housing 43), the second cable 484 is rotatable relative to the housing body 43A about the central axis P4 of the housing body 43A, and during the rotation of the second cable 484 relative to the housing body 43A about the central axis P4 of the housing body, the second cable 484 is always in electrical conduction with the corresponding electronic component terminal 493.

[0272] Furthermore, the cooking appliance 600 is configured such that the central axis P4 of the housing body coincides or substantially coincides with the central axis PA of the wire coil assembly, the housing body 43A rotates relative to the wire coil holder 180 under the drive of the drive device 50, and the housing body 43A drives the cooking container 30 to rotate synchronously. It can be understood that the first opening 435 and the temperature-sensing cover 43B are located at the first end 431, the second opening 436 is located at the second end 432, the second cable 484 is the cable of the temperature sensor assembly 40, and the second opening 436 is the outlet for leading out the cable.

[0273] Preferably, the temperature-sensing fuse assembly 49 further includes a fuse 492. The fuse 492 also contacts or is close to the temperature-sensing cover 43B. When the temperature of the cooking container 30 is too high, the fuse 492 melts, thereby avoiding safety problems.

[0274] As Figure 8 and Figure 11 shown, an installation portion 4373 is provided in the installation cavity 437. The installation portion 4373 is correspondingly arranged with the electronic components of the temperature-sensing fuse assembly 49 for carrying the corresponding electronic components. The installation portion 4373 is connected to the side wall of the installation cavity 437. The installation portion 4373 is provided with an opening for the electronic component terminal 493 to pass through, or there is a gap between the installation portion 4373 and the side wall of the installation cavity 437 for the electronic component terminal 493 to pass through. For example, the installation portion 4373 is configured as a support groove, such that the temperature-sensing fuse assembly 49 is clamped between the support groove and the temperature-sensing cover 43B. The thermistor 491 and the fuse 492 are usually cylindrical and have a small contact area with the support groove. Therefore, preferably, silicone grease 4374 is filled between the temperature-sensing fuse assembly 49 and the temperature-sensing cover 43B, so that the positions of the respective electronic components are stable and the heat conduction performance is not affected.

[0275] Preferably, the wiring assembly 40A further includes at least two first wiring terminals 471. The first wiring terminals 471 are arranged corresponding to the electronic component wiring terminals 493, and the first wiring terminals 471 are also arranged corresponding to the second cable 484. The first wiring terminals 471 are connected between the corresponding electronic component wiring terminals 493 and the second cable 484, so that the corresponding second cable 484 is electrically connected to the electronic component wiring terminals 493. Among them, the temperature sensor assembly 40 is configured such that the first wiring terminals 471 remain in a fixed position relative to the housing body 43A, and during the rotation of the second cable 484 around the central axis P4 of the housing body relative to the housing body 43A, the second cable 484 and the corresponding first wiring terminals 471 always remain electrically connected.

[0276] Preferably, the wiring assembly 40A further includes a second wiring terminal 481. The second wiring terminal 481 is arranged corresponding to the first wiring terminal 471. Therefore, the second wiring terminal 481 is also arranged corresponding to the second cable 484. The second wiring terminal 481 is connected between the corresponding first wiring terminal 471 and the second cable 484, so that the corresponding second cable 484 is electrically connected to the first wiring terminal 471. Among them, the temperature sensor assembly 40 is configured such that the second wiring terminal 481 and the second cable 484 can rotate synchronously around the central axis P4 of the housing body relative to the housing body 43A, and during the rotation of the second cable 484 around the central axis P4 of the housing body relative to the housing body 43A, the second wiring terminal 481 and the corresponding first wiring terminal 471 always remain electrically connected.

[0277] Specifically, as Figure 11 shown, the first wiring terminal 471 has a first connection portion 4711 for connecting the second wiring terminal 481, and the second wiring terminal 481 has a second connection portion 4811 for connecting the first wiring terminal 471. At least a part of one of the first connection portion 4711 and the second connection portion 4811 is configured as at least a part of a first metal ring, and the axis of the first metal ring is the central axis P4 of the housing body. The other of the first connection portion 4711 and the second connection portion 4811 includes at least one metal contact arm 4814. Among them, the temperature sensor assembly 40 is configured such that the metal contact arm 4814 contacts at least a part of the first metal ring, and the metal contact arm 4814 can rotate around the central axis P4 of the housing body relative to the housing body 43A. Thus, the revolution axis of the metal contact arm 4814 coincides with the axis of the first metal ring. Therefore, during the rotation of the metal contact arm 4814, it can always contact at least a part of the first metal ring, that is, the first wiring terminal 471 and the second wiring terminal 481 always remain conductive.

[0278] Further, in order to enable the metal contact arm 4814 to be well connected to the first metal ring, the other of the first connecting portion 4711 and the second connecting portion 4811 further includes at least a part of the second metal ring 4813, and at least one metal contact arm 4814 is arranged at intervals along the circumferential direction of the second metal ring on the second metal ring 4813. The axis of the second metal ring 4813 is the central axis P4 of the housing body, and the second metal ring 4813 is rotatable relative to the housing body 43A about the central axis P4 of the housing body. Thus, the second metal ring 4813 can support the metal contact arm 4814, so that the metal contact arm 4814 is arranged in a circumferential manner to make good contact with the first metal ring.

[0279] In the illustrated embodiment, the first connecting portion 4711 is configured as the first metal ring, and the second connecting portion 4811 includes at least a part of the second metal ring 4813 and the metal contact arm 4814 (for example, two metal contact arms 4814 are provided corresponding to each first metal ring 4711).

[0280] The temperature sensor assembly 40 has a plurality of electronic component terminals 493, and thus has a plurality of first metal rings and a plurality of first metal contact arms 4814. Preferably, at least a part of all the first metal rings 4711 are distributed at intervals from the inside to the outside in the radial direction of the housing body 43A, so that the plurality of first metal rings 4711 do not affect each other. Further preferably, all the first metal rings 4711 are distributed at intervals from the inside to the outside in the radial direction of the housing body 43A. More preferably, all the first metal rings 4711 are equally spaced from the inside to the outside in the radial direction of the housing body 43A.

[0281] Preferably, the wiring assembly 40A further includes a first temperature sensing signal transmission assembly 47, and the first temperature sensing signal transmission assembly 47 includes a first bracket 472 and a first terminal 471. The first bracket 472 is arranged in the installation cavity 437 and connected to the side wall of the installation cavity 437, so that the first bracket 472 is non-rotatable relative to the housing body 43A. The first terminal 471 is arranged on the first bracket 472.

[0282] For example, as Figure 11 shown, the first bracket 472 is generally in the shape of a circular plate. The first bracket 472 is provided with at least two first through slots 473, and the first through slots 473 are arranged corresponding to the first terminals 471. As Figure 12As shown, the first terminal 471 extends through the corresponding first through slot 473, such that a part of the first terminal 471 is located on the side of the first bracket 472 facing the first opening 435, and another part is located on the side of the first bracket 472 facing the second opening 436. Among them, the part of the first terminal 471 located on the side of the first bracket 472 facing the second opening 436 is the first connecting portion 4711, and the part of the first terminal 471 located on the side of the first bracket 472 facing the first opening 435 is used to connect to the electronic component terminal 493.

[0283] The first terminal 471 is composed of a first connecting portion 4711 and a third connecting portion 4712. The third connecting portion 4712 is provided on the first metal ring 4711, and for example, it can be integrally formed with the first metal ring (for example, the third connecting portion 4712 and the first metal ring 4711 are made of the same piece of metal). The part of the first terminal 471 located on the side of the first bracket 472 facing the first opening 435 is, for example, a part of the third connecting portion 4712. In the illustrated embodiment, the third connecting portion 4712 is used to extend upward through the first through slot 473 from bottom to top. There may be an interference fit between the third connecting portion 4712 and the first through slot 473. The third connecting portion 4712 and the electronic component terminal 493 may be connected by welding.

[0284] As Figure 13 shown, one of the first bracket 472 and the side wall of the installation cavity 437 is provided with a rib 4724, and the other of the first bracket 472 and the side wall of the installation cavity 437 is provided with a groove 4371 for receiving the rib 4724. The groove 4371 extends along the axial direction of the housing body 43A to make the first bracket 472 non-rotatable relative to the housing body 43A. In the illustrated embodiment, the first bracket 472 is provided with a rib 4724, and the side wall of the installation cavity 437 is provided with a groove 4371.

[0285] The side wall of the installation cavity 437 may also be provided with at least one first support protrusion (not shown) extending toward the middle of the installation cavity 437. The first support protrusion is used to contact the side of the first bracket 472 facing the second opening 436, so that the first support protrusion can support the first temperature sensing signal transmission assembly 47. The first bracket 472 is made of, for example, plastic and resin materials. During installation, it is inserted into the installation cavity 437 from the second opening 436, and it can reach the predetermined installation position by utilizing its own elastic deformation performance to pass over the first support protrusion.

[0286] Preferably, the wiring assembly 40A further includes a second temperature sensing signal transmission assembly 48. The second temperature sensing signal transmission assembly 48 includes a second bracket 482, a second terminal 481, and a second cable 484. The second bracket 482 is disposed in the installation cavity 437 and connected to the side wall of the installation cavity 437. The second bracket 482 is located between the first bracket 472 and the second opening 436. The second bracket 482 is rotatable relative to the housing body 43A about the central axis P4 of the housing body. The second terminal 481 is disposed on the second bracket 482. The second cable 484 is connected to the second terminal 481, so that the second temperature sensing signal transmission assembly 48 is rotatable relative to the housing body 43A about the central axis P4 of the housing body.

[0287] For example, as Figure 11 shown, the second bracket 482 is generally in the shape of a circular plate. The second bracket 482 is provided with at least two second through grooves 483. The second through grooves 483 are correspondingly arranged with the second terminal 481. The second terminal 481 extends through the corresponding second through groove 483, so that a part of the second terminal 481 is located on the side of the second bracket 482 facing the first opening 435, and another part of the second terminal 481 is located on the side of the second bracket 482 facing the second opening 436. Wherein, the part of the second terminal 481 located on the side of the second bracket 482 facing the first opening 435 is the second connecting portion 4811, and the part of the second terminal 481 located on the side of the second bracket 482 facing the second opening 436 is used to connect the second cable 484.

[0288] The second terminal 481 is composed of a second connecting portion 4811 and a fourth connecting portion 4812. The second connecting portion includes at least part of a metal contact arm 4814 and a second metal ring 4813. The metal contact arm 4814 and the fourth connecting portion 4812 are respectively disposed on both sides of the second metal ring 4813. The metal contact arm 4814, the second metal ring 4813, and the fourth connecting portion 4812 are formed as a whole, for example, made of the same piece of metal. The part of the second terminal 481 located on the side of the second bracket 482 facing the second opening 436 is, for example, a part of the fourth connecting portion 4812. The fourth connecting portion 4812 extends downward through the second through groove 483. An interference fit may be provided, for example, between the fourth connecting portion 4812 of the second terminal 481 and the second through groove 483. The fourth connecting portion 4812 of the second terminal 481 and the second cable 484 may be connected by welding, for example.

[0289] Preferably, a second groove 486 is provided on the side of the second bracket 482 facing the first opening 435. The second groove 486 is correspondingly arranged with the second through groove 483 and communicates with the corresponding second through groove 483. The second groove is used to accommodate a part of the second connecting portion 4811. For example, the second groove 486 is configured as an arc-shaped groove for accommodating the second metal ring 4813, so that the second bracket 482 can stably support the second terminal 481. Preferably, two second grooves 486 are correspondingly arranged for one second through groove 483, and the two second grooves 486 are respectively located on both sides of the second through groove 483.

[0290] As Figure 8 shown, an annular groove 4372 with the central axis P4 of the housing body as the axis is provided on the side wall of the installation cavity 437. The annular groove 4372 is used to accommodate the outer peripheral portion of the second bracket 482, so that the second bracket 482 can rotate in the annular groove 4372, that is, it can rotate relative to the housing body 43A. It can be understood that the annular groove 4372 also plays a role in supporting the second temperature sensing signal transmission component 48. The second bracket 482 is made of plastic and resin materials, for example. During installation, it is inserted into the installation cavity 437 from the second opening 436, and it can enter the annular groove 4372 by using its own elastic deformation performance.

[0291] The electronic component terminal 493 is configured as a flexible conductive wire, for example. During assembly, the electronic component terminal 493 is reserved with enough length. First, it is welded to the first terminal 471 outside the installation cavity 437, and then the first temperature sensing signal transmission component 47 and the second temperature sensing signal transmission component 48 are successively loaded into the installation cavity 437 from the second opening 436. After assembly, the electronic component terminal 493 is coiled in the installation cavity 437 by using its own flexibility.

[0292] As Figure 8 、 Figure 10 and Figure 11 shown, a second connecting member 485 is provided on the side of the second bracket 482 facing the second opening 436. The second connecting member 485 is used to connect the base 26 of the cooking appliance 600. The second connecting member 485 is configured as a plug board, for example. The base 26 is provided with a slot for accommodating the plug board. When the temperature sensor assembly 40 is installed on the cooking appliance 600, the second connecting member 485 makes the second temperature sensing signal transmission component 48 non-rotatable relative to the base 26 and the cooking pot body 20. However, since the second temperature sensing signal transmission component 48 is rotatable relative to the first temperature sensing signal transmission component 47 and the housing 43, the first temperature sensing signal transmission component 47 and the housing 43 of the temperature sensor assembly 40 are rotatable relative to the base 26 and the cooking pot body 20. Furthermore, the housing 43 can drive the cooking container 30 to rotate relative to the base 26 and the cooking pot body 20.

[0293] In summary, as Figure 11As shown, in the present application, the housing 43, the temperature-sensing fuse assembly 49, and the first temperature-sensing signal transmission assembly 47 of the temperature-sensing device 40 form the rotating member 44 of the temperature-sensing device 40. The first temperature-sensing signal transmission assembly 47 is accommodated in the housing 43 (specifically, the housing body 43A) and is electrically connected to the second temperature-sensing signal transmission assembly. The rotating member 44 can be driven to rotate around the central axis P4 of the housing body relative to the second temperature-sensing signal transmission assembly 48. Specifically, both the temperature-sensing fuse assembly 49 and the first temperature-sensing signal transmission assembly 47 are fixed in position relative to the housing 43, and the housing 43 can be driven to rotate around the central axis P4 of the housing body relative to the second temperature-sensing signal transmission assembly 48. The temperature-sensing fuse assembly 49 and the first temperature-sensing signal transmission assembly 47 are driven by the housing 43 and can rotate around the central axis P4 of the housing body relative to the second temperature-sensing signal transmission assembly 48.

[0294] As Figure 8 shown, the wire coil device 660 of the cooking appliance 600 further includes a clutch member 46 for detachably connecting to the bottom surface of the cooking container 30. When the cooking container 30 is placed in the accommodation cavity 21, the clutch member 46 contacts the bottom of the cooking container 30. The clutch member 46 is connected to the housing 43, for example, disposed at the first end 431 of the housing 43, for example, sleeved on the outer periphery of the temperature-sensing cover 43B, so that the clutch member 46 and the housing 43 can rotate synchronously around the central axis P4 of the housing body relative to the cooking pot body 20. For example, the cooking container 30 includes ferromagnetic material, and the clutch member 46 is configured to be magnetic, so that the two are magnetically attracted; and / or, the clutch member 46 is configured to be engaged with the bottom surface of the cooking container 30.

[0295] As Figure 6 shown, the clutch member 46 is provided with a limiting through hole 461, for example. The first end 431 of the housing 43 passes through the limiting through hole 461 so that the clutch member 46 is sleeved on the first end 431. As Figure 8 , Figure 9 and Figure 11 shown, the housing 43 of the temperature sensor assembly 40 further includes a second blocking portion 434 extending radially outward for contacting one side of the second end 432 of the clutch member 46 facing the housing 43. Thus, the clutch member 46 can have a stable axial position.

[0296] The structure of the wire coil device 660 is introduced below.

[0297] As described above, the wire spool device 660 includes a temperature sensor assembly 40 and a wire spool assembly 670. The wire spool assembly 670 includes a spool holder 180, and a disk-shaped winding 182 is disposed on the spool holder 180. For example, the disk-shaped winding 182 is disposed on one side of the spool holder 180 facing the second end portion 432. The central axis P8 of the spool holder is also the central axis PA of the wire spool assembly. The axial direction of the spool holder 180 is also the axial direction of the wire spool assembly 670. The radial direction of the spool holder 180 is also the radial direction of the wire spool assembly 670. The circumferential direction of the spool holder 180 is also the circumferential direction of the wire spool assembly 670.

[0298] In the present application, the driving device 50 is used to drive the housing 43 to rotate relative to the spool holder 180 about the central axis P4 of the housing body.

[0299] As Figure 6 shown, a wire spool through hole 188A is provided at the central portion of the spool holder 180, and the wire spool through hole 188A extends along the axial direction of the spool holder 180. Among them, the temperature sensor assembly 40 is adapted to the wire spool through hole 188A, so that at least a part of the temperature sensor assembly 40 can rotate relative to the spool holder 180 about the central axis 8 of the spool.

[0300] For example, the temperature sensor assembly 40 is disposed in the wire spool through hole 188A. That is, the spool holder 180 is sleeved on the outer periphery of the housing body 43A. The side wall of the wire spool through hole 188A is connected to the outer peripheral surface of the temperature sensor assembly 40 (i.e., the side wall of the mounting cavity 437) through a revolute pair structure 161. Among them, the axis of the revolute pair structure 161 coincides or substantially coincides with the central axis P8 of the spool holder. Optionally, the revolute pair structure 161 is configured as a rolling bearing, so that the inner ring of the rolling bearing 161 is tightly fitted with the outer peripheral surface of the housing 43, and the outer ring of the rolling bearing 161 is tightly fitted with the inner peripheral surface of the wire spool through hole 188A. As an alternative embodiment, the revolute pair structure 161 can also be selectively configured as a sliding bushing (not shown in the figure). In order to prevent electromagnetic interference, the revolute pair structure 161 is further selectively made of a non-metallic material.

[0301] For example, a cylindrical portion 188C (see Figure 5 and Figure 8 ) is provided at the central portion of the spool holder 180, and the wire spool through hole 188A is formed inside the cylindrical portion 188C. The first end portion 431 and the second end portion 432 of the housing 43 respectively pass through the wire spool through hole 188A from both ends of the cylindrical portion 188C.

[0302] On the inner peripheral surface of the wire spool through-hole 188A, a blocking surface 188B is provided that extends in the radial direction of the wire spool through-hole 188A toward the temperature sensor assembly 40. The housing 43 of the temperature sensor assembly 40 further includes a first blocking portion 433 that extends radially outward. The wire spool device 660 is configured such that the rotary pair structure 161 is axially limited between the blocking surface 188B and the first blocking portion 433 along the axial direction of the wire spool holder 180. Thus, the rotary pair structure 161 has a stable axial position.

[0303] As Figure 9 shown, on the outer peripheral surface of the housing body 43A of the housing 43 of the temperature sensor assembly 40, a connection structure 45 for connecting the driving device 50 is provided, so that the temperature sensor assembly 40 can rotate relative to the wire spool holder 180 around the wire spool center axis P8 under the drive of the driving device 50, wherein the connection structure 45 is provided on the side of the first blocking portion 433 facing the second end portion 432.

[0304] As described above, the driving device 50 includes a second transmission wheel 58. The second transmission wheel 58 is a ring structure and is used to sleeved on the outer peripheral surface of the temperature sensor assembly 40. Specifically, it is sleeved on the outer peripheral surface of the housing body 43A of the housing 43. The connection structure 45 is used to connect the second transmission wheel 58.

[0305] Specifically, the connection structure 45 includes a first limiting stop surface 453. The first limiting stop surface 453 extends radially outward from the outer peripheral surface of the temperature sensor assembly 40 and faces the second end portion 432, and is used to limit the transmission wheel 58 from moving toward the wire spool holder 180 along the axis direction of the temperature sensor assembly 40.

[0306] As Figure 7 shown, at least one second connection body 58F is provided on the inner peripheral surface of the second transmission wheel 58. The connection structure 45 further includes at least one first connection body 451. The first connection body 451 is used to be correspondingly arranged with the second connection body 58F and connect the second connection body 58F. The first connection body 451 is closer to the second end portion 432 than the first limiting stop surface 453. When the second transmission wheel 58 is installed in the set position, the first connection body 451 is engaged with the second connection body 58F to limit the second transmission wheel 58 from rotating relative to the connection structure 45. In the illustrated embodiment, the connection structure 45 includes a plurality of first connection bodies 451, and the plurality of first connection bodies 451 are arranged at intervals along the circumferential direction of the temperature sensor assembly 40, for example, arranged at equal intervals.

[0307] Preferably, the second connecting body 58F is a limiting groove provided on the inner peripheral surface of the second driving wheel 58. The limiting groove extends along the axial direction of the second driving wheel 58. The first connecting body 451 is a rib provided on the outer peripheral surface of the temperature sensor assembly 40. The limiting groove of the second connecting body 58F is used to accommodate the rib of the first connecting body 451.

[0308] The connecting structure 45 further includes at least one second limiting stopper 456. The second limiting stopper 456 is provided on the outer peripheral surface of the housing body 43A of the housing 43 of the temperature sensor assembly 40. One side of the second limiting stopper 456 facing the first end portion 431 includes a second limiting stop surface 454. The second limiting stop surface 454 extends outward from the outer peripheral surface of the temperature sensor assembly 40 in the radial direction of the temperature sensor assembly 40. The second limiting stop surface 454 is closer to the second end portion 432 than the first limiting stop surface 453. The second limiting stop surface 454 is used to jointly define the axial position of the second driving wheel 58 with the first limiting stop surface 453.

[0309] The second limiting stopper 456 has a first outer surface 455 on the side facing away from the central axis P4 of the temperature sensor assembly 40. The first outer surface 455 is configured to be inclined with respect to the central axis P4 of the temperature sensor assembly 40, such that the distance between the end of the first outer surface 455 facing the second end portion 432 and the central axis P4 of the temperature sensor assembly 40 is less than the distance between the end of the first outer surface 455 facing the first end portion 431 and the central axis P4 of the temperature sensor assembly 40. The portions of the housing body 43A of the housing 43 of the temperature sensor assembly 40 located on both sides of the second limiting stopper 456 in the circumferential direction of the temperature sensor assembly 40 are configured as functional grooves 457 extending along the axial direction of the temperature sensor assembly 40. The functional grooves 457 penetrate through the side walls of the housing body 43A of the housing 43 of the temperature sensor assembly 40.

[0310] The housing body 43A is made of materials such as plastic and resin, for example. When installing the second driving wheel 58 on the housing body 43A, the second driving wheel 58 is sleeved from the second end portion 432. The first outer surface 455 functions as a guide and is also referred to as a guiding inclined surface. The second limiting stop 456 is also referred to as a limiting and guiding structure. Under the action of the guiding inclined surface 455, the second driving wheel 58 can be conveniently moved to a preset position. Meanwhile, by providing through functional grooves 457 on both sides of the limiting and guiding structure 456, when installing the second driving wheel 58, the limiting and guiding structure 456 in a cantilever state will swing towards the inside of the installation cavity 437, making it easier to install the second driving wheel 58 to the set position. When the second driving wheel 58 reaches the preset position (after crossing the second limiting stop surface 454), the limiting and guiding structure 456 will reset by utilizing its own elastic deformation ability, such that the second driving wheel 58 is clamped between the second limiting stop surface 454 and the first limiting stop surface 453.

[0311] In the illustrated embodiment, the connection structure 45 includes a plurality of second limiting stops 456, and the plurality of second limiting stops 456 are arranged at intervals along the circumferential direction of the temperature sensor assembly 40, for example, arranged at equal intervals.

[0312] In summary, the temperature sensor assembly 40 includes a housing 43 for contacting the bottom surface of the cooking container 30 and a cable (specifically, the second cable 484) extending from the housing 43, wherein the cable 484 is used to keep the relative position with the coil rack 180 unchanged (for example, the cable 484 is mechanically connected to the coil rack 180 through the cavity wall of the accommodating cavity 21, so that the two keep the relative position unchanged). The coil device 660 is configured such that the housing 43 can rotate relative to the cable 484 around the coil rack central axis P8, so as to drive the cooking container 30 to rotate synchronously relative to the cable 484 around the coil rack central axis P8, thereby enabling the cooking container 30 to rotate relative to the coil rack 180 around the coil rack central axis P8.

[0313] According to the present application, the components of the temperature sensor assembly 40 can move relative to each other, such that the temperature sensor assembly 40 has more application scenarios. Of course, the temperature sensor assembly 40 can also be applied to situations where relative movement between components is not required. The coil device 660 can rotate the cooking container 30, so that the intended purpose can be achieved by rotation. For example, rotating the cooking container 30 relative to the magnetic field of electromagnetic heating, so that the heated part of the cooking container 30 moves on the cooking container 30, realizing uniform heating of the cooking container 30. Meanwhile, the coil device 660 can also monitor the temperature of the cooking container 30. The cooking appliance 600 includes all the features and effects of the temperature sensor assembly 40 and the coil device 660.

[0314] It should be noted that the cooking appliance according to the present application can be one of an electric rice cooker, an electric slow cooker, and an electric pressure cooker, or a cooking appliance similar to these cooking appliances.
