For example, in some embodiments, at least a portion of the driving portion can rotate, and the rotating portion is in transmission fit with the driving fitting portion to drive the driving fitting portion to rotate, so as to drive the pot 20 to rotate. For another example, in other embodiments, one of the driving portion and the driving fitting portion is adapted to generate an alternating magnetic field, and under the action of the alternating magnetic field, the other and one of the driving portion and the driving fitting portion can rotate relatively, so as to realize magnetic driving rotation. The matching mode of magnetic drive rotation enables the driving part and the driving matching part to be free from mechanical connection, therefore, the driving part can be installed on the base body 10, the weight of the cookware 20 is reduced, the electric connection structure of the cookware 20 is simplified, or the cookware 20 is not required to be provided with the electric connection structure, the cookware 20 can be conveniently taken and placed and cleaned, and the use safety and the service life are improved.

For example, by providing the stator assembly 40 and the rotor assembly 50, in some embodiments, the pot 20 is enabled to rotate clockwise relative to the housing 10; in other embodiments, the cooker 20 can rotate counterclockwise relative to the seat 10; in still other embodiments, the cooker 20 can rotate clockwise relative to the seat 10 and counterclockwise relative to the seat 10 (as shown by arrows a-a in fig. 1 and 2).

And, rotor subassembly 50 can realize rotating under the effect of the alternating magnetic field that stator module 40 produced, can need not to carry out mechanical connection between stator module 40 and the rotor subassembly 50, consequently, stator module 40 can install in pedestal 10, so that stator module 40 is connected with the power and produces alternating magnetic field, the weight of pan 20 has been alleviateed on the one hand, on the other hand has simplified the electric connection structure of pan 20, or need not to set up electric connection structure on the pan 20, the getting of pan 20 of being convenient for is put, wash, safety in utilization and life have been improved.

Of course, in other embodiments, the stator assembly 40 and the rotor assembly 50 may be interchanged, specifically, the driving portion is the rotor assembly 50, the driving fitting portion is the stator assembly 40, and the driving fitting portion generates the alternating magnetic field, so that the rotor assembly 50 can rotate relative to the stator assembly 40 under the action of the alternating magnetic field, thereby providing the driving force for the rotation of the pot 20. This is also within the scope of the invention.

According to the cooking utensil 100 of the embodiment of the invention, the pot 20 can rotate relative to the base 10 by arranging the driving part and the driving matching part, so that the diner can conveniently clamp food materials, the pot 20 is easy to separate from the base 10 so as to conveniently take, place and clean the pot 20, and the pot 20 is simpler in structure and lighter in weight.

According to some embodiments of the present invention, the rotor assembly 50 includes a permanent magnet 51, and the permanent magnet 51 can rotate relative to the stator assembly 40 under the driving of the alternating magnetic field generated by the stator assembly 40, so as to smoothly drive the pot 20 to rotate. And the permanent magnet 51 has magnetism itself, need not to be connected with the power and can induce alternating magnetic field, the structure of rotor subassembly 50, it is easier to set up the position design, the structure of pan 20 is also simpler, for example in some embodiments, rotor subassembly 50 locates pan 20, make pan 20 and the part on pan 20 (including rotor subassembly 50) all need not to be connected with the power, pan 20 structure has been simplified greatly, avoid electric connection structure to damage in the cleaning process of pan 20, and cooking utensil 100 only seat 10 or the part on the seat 10 need be connected with the power, power supply part quantity such as power plug of cooking utensil 100 has been reduced.

In some embodiments of the present invention, as shown in fig. 3 and 4, the stator assembly 40 includes a stator coil 41, and the rotor assembly 50 includes a permanent magnet 51, wherein the permanent magnet 51 and the stator coil 41 are distributed at intervals along the rotation axis of the pot 20, for example, distributed up and down as shown in fig. 3 and 4, so that the permanent magnet 51 is more uniformly located in the range of the alternating magnetic field of the stator coil 41, and the force applied to each position of the permanent magnet 51 is more uniform, which facilitates the rotation of the permanent magnet 51.

Furthermore, as shown in FIG. 4, the spacing between the stator coil 41 and the permanent magnet 51 is less than or equal to 15mm, i.e., L1 ≦ 15mm, for example, in some embodiments, the spacing L1 between the stator coil 41 and the permanent magnet 51 may be 14mm, 12mm, 10mm, 8mm, 6mm, 4mm, 2mm, and so on. Too large distance between the stator coil 41 and the permanent magnet 51 may cause the permanent magnet 51 not to be completely located within the magnetic field range generated by the stator coil 41, or the magnetic field strength at the position of the permanent magnet 51 is too small, resulting in too small force for driving the permanent magnet 51 to rotate, and further affecting the permanent magnet 51 to drive the cookware 20 to rotate smoothly. Within the above size range, at least most of the permanent magnet 51 is located within the range of the alternating magnetic field generated by the stator coil 41, and the magnetic field strength at the position where the permanent magnet 51 is located is large enough, so that the permanent magnet 51 can smoothly drive the pot 20 to rotate, and the weight of food materials allowed to be contained in the pot 20 is larger.

In a further embodiment of the present invention, as shown in FIG. 4, the stator coil 41 is spaced from the permanent magnet 51 by a distance equal to 5mm, or equal to 10mm, or greater than 5mm and less than 10mm, i.e., 5mm L1 is 10 mm. An excessively small distance between the stator coil 41 and the permanent magnet 51 may cause an excessively large attraction force between the permanent magnet 51 and the stator coil 41 or other metal parts on the housing 10, thereby increasing the resistance to rotation of the permanent magnet 51. In the size range, the permanent magnet 51 can be located more in the range of the alternating magnetic field generated by the stator coil 41, the magnetic field intensity of the position where the permanent magnet 51 is located is large enough, and the rotation resistance of the permanent magnet 51 is small, so that the permanent magnet 51 can drive the cookware 20 to rotate more easily.

According to some embodiments of the present invention, as shown in fig. 3 and 4, the projection of the permanent magnet 51 on the upper surface of the seat body 10 is located in the projection of the stator coil 41 on the upper surface of the seat body 10, so as to further ensure that the permanent magnet 51 can be located in the range of the alternating magnetic field generated by the stator coil 41, and to facilitate improving the uniformity of the force applied by the permanent magnet 51 in the alternating magnetic field.

For example, in some specific embodiments, as shown in fig. 4, the permanent magnet 51 is a ring-shaped permanent magnet, the stator coil 41 is formed as a ring-shaped coil, the inner diameter of the ring-shaped permanent magnet is greater than or equal to the inner diameter of the ring-shaped coil, and the outer diameter of the ring-shaped permanent magnet is less than or equal to the outer diameter of the ring-shaped coil. The projection of the permanent magnet 51 on the upper surface of the seat body 10 is completely positioned in the projection of the stator coil 41 on the upper surface of the seat body 10, the coaxiality of the permanent magnet 51 and the stator coil 41 is improved, and the stress uniformity of the permanent magnet 51 is improved. For example, in some embodiments, the annular permanent magnet is disposed coaxially with the annular coil, so that the effect of improving the force uniformity of the permanent magnet 51 is better.

It should be noted that the term "toroidal coil" is to be understood broadly, and includes both a single-turn coil and a multi-turn spirally-extending coil, wherein the inner diameter of the innermost coil in the multi-turn spirally-extending coil is the inner diameter of the toroidal coil, and the outer diameter of the outermost coil is the outer diameter of the toroidal coil.

In the embodiment that the rotor assembly 50 includes the permanent magnet 51, the permanent magnet 51 may also be magnetically attracted to the pot 20 to achieve the fixing of the rotor assembly 50, the rotor assembly 50 does not need other fixing structures or only needs other simple fixing structures (for example, the fixing may also be performed by gluing), and the fixing of the rotor assembly 50 is simpler and firmer.

In some embodiments, as shown in fig. 4 and fig. 6, the bottom wall of the pot 20 is provided with a matching groove 201, and at least a part of the driving matching portion is located in the matching groove 201, so that on one hand, the structure of the pot 20 and the driving matching portion is more compact, and the adjustment of the distance between the pot 20 and the seat body 10 is facilitated, and on the other hand, the matching groove 201 can also play a limiting role in the driving matching portion, thereby improving the stability of fixing the driving matching portion. In addition, the part of the driving matching part extending into the matching groove 201 can also be magnetically attracted with the groove wall of the matching groove 201, so that the reliability of positioning and fixing of the driving matching part is improved. For example, in the embodiment that the driving engagement portion is the rotor assembly 50, and the rotor assembly 50 includes the permanent magnet 51, the outer circumferential edge of the permanent magnet 51 cooperates with the inner circumferential surface of the engagement groove 201 to achieve positioning of the rotor assembly 50, and the permanent magnet 51 can be magnetically attracted to the groove wall of the engagement groove 201 all the time, and the attraction area is large, and the attraction is more reliable.

According to some embodiments of the present invention, as shown in fig. 3 and 4, the heating assembly 30 includes an electromagnetic coil 31, the electromagnetic coil 31 is used for generating an alternating magnetic field, at least a portion of the pot 20 is located in the alternating magnetic field generated by the electromagnetic coil 31, so that the pot 20 can generate heat under the action of the alternating magnetic field, and an electromagnetic induction heating function is realized, and a mechanical connection between the pot 20 and the seat body 10 is not required, thereby facilitating the taking, placing and cleaning of the pot 20. In some embodiments, the alternating magnetic field generated by the stator assembly 40 can also perform electromagnetic induction heating on the pot 20 to further improve the heating efficiency and effect of the pot 20.

In addition, as shown in fig. 4, the driving part is the stator assembly 40, the stator assembly 40 includes the stator coil 41, one of the electromagnetic coil 31 and the stator coil 41 is disposed around the other, i.e., the electromagnetic coil 31 is disposed around the stator coil 41 or the stator coil 41 is disposed around the electromagnetic coil 31, so that the stator assembly 40 and the heating assembly 30 on the housing 10 are more compact. For example, in the example shown in fig. 4, the electromagnetic coil 31 is disposed around the stator coil 41, so that the stator coil 41 is disposed closer to the middle of the base 10, after the pot 20 is placed on the base 10, the rotor assembly 50 is more easily located within the range of the alternating magnetic field of the stator coil 41, the pot 20 does not need to be specially aligned, the use is more convenient, and the extension range of the electromagnetic coil 31 can be larger, so that the pot 20 can be heated from a larger range, and the uniformity of heating of the pot 20 is improved.

As shown in FIG. 4, the distance between the electromagnetic coil 31 and the pot 20 is less than or equal to 15mm, i.e. L2 ≦ 15mm, for example, in some embodiments, the distance L2 between the electromagnetic coil 31 and the pot 20 may be 14mm, 12mm, 10mm, 8mm, 6mm, 4mm, 2mm, etc. The too big interval of solenoid 31 and pan 20 can lead to pan 20 heating range little or heat inhomogeneous, and in above-mentioned size range, solenoid 31 and pan 20's interval is more suitable, makes pan 20 most region can be in solenoid 31's alternating magnetic field to increase pan 20's heated area, and improve the homogeneity to pan 20 heating.

In a further embodiment of the invention, as shown in fig. 4, the distance between the electromagnetic coil 31 and the pot 20 is equal to 5mm, or equal to 10mm, or greater than 5mm and less than 10mm, i.e. 5mm ≦ L2 ≦ 10 mm. The small distance between the electromagnetic coil 31 and the pot 20 increases the resistance of the pot 20 to rotate. In the above size range, the pot 20 can be located more within the range of the alternating magnetic field generated by the electromagnetic coil 31, and the rotational resistance of the pot 20 is small.

In some embodiments of the present invention, the electromagnetic coil 31 and the stator coil 41 are separate coils, so that the electromagnetic coil 31 and the stator coil 41 can be controlled independently, i.e. the electromagnetic heating function and the rotation function of the pot 20 can be controlled independently, and the cooking appliance 100 is more convenient to use.

In other embodiments of the present invention, the electromagnetic coil 31 and the stator coil 41 are integrated coils, which is beneficial to simplify the processing procedure, and the working states of the electromagnetic coil 31 and the stator coil 41 are consistent and can be controlled together, which is beneficial to simplify the control circuit and the power supply circuit.

According to some embodiments of the present invention, as shown in fig. 3 and 4, the cooking appliance 100 further includes a supporting member 60, the supporting member 60 may be disposed between the pot 20 and the seat 10, or may be disposed between the driving matching portion (e.g., the rotor assembly 50) and the seat 10 as shown in fig. 4, the supporting member 60 is supported on the seat 10 to enable the pot 20 and the seat 10 to be separated by a predetermined gap, and the pot 20 and the seat 10 are not in direct contact with each other, so as to effectively reduce the resistance to the rotation of the pot 20 relative to the seat 10.

In some embodiments, the predetermined gap is equal to 1mm, or equal to 5mm, or greater than 1mm and less than 5mm, i.e., 1mm L3 5mm, for example in some embodiments, the predetermined gap L3 may be 2mm, 3mm, 4mm, and so forth. In above-mentioned size range, avoid pan 20 for support piece 60 slope or because machining error leads to taking place the contact between pan 20 and the pedestal 10, it is effectual to reduce pan 20 rotation resistance, and prevents that the too big center that leads to pan 20 in predetermined clearance is too high, is favorable to improving pan 20's stability.

According to some embodiments of the present invention, the supporting member 60 may be a rolling bearing, a sliding bearing or a ball bearing, so as to realize rolling friction or sliding friction, so as to further reduce the resistance of the pot 20 to rotate relative to the seat body 10, and enhance the stability of the rotational operation of the pot 20 after containing food materials.
