Description

[0001] This application claims priority to Chinese Patent Application No. 202510214807.3, filed on February 25, 2025, entitled "Heating Component and Household Appliance", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of household appliance technology, and more specifically, to a heating component and a household appliance. Background Technology

[0003] In related technologies, household appliances include heating elements. When the appliance is in heating mode, the heating element operates and generates heat. Temperature regulation of the heating element relies on external sensors, resulting in slow response and low temperature control accuracy, thus reducing the appliance's performance. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this application proposes a heating assembly.

[0006] The second aspect of this application proposes a household appliance.

[0007] In view of the above, a first aspect of this application provides a heating assembly for a household appliance, comprising: a power unit; a connecting part connected to the power unit, the power unit driving the connecting part to rotate; a heating plate; a magnetic element, one of the heating plate and the magnetic element being connected to the connecting part and capable of rotating with the connecting part; a connecting structure, the other of the heating plate and the magnetic element being movably connected to the connecting part through the connecting structure, the connecting part being capable of rotating relative to the connecting structure; and the heating plate being able to heat up when one of the heating plate and the magnetic element rotates with the connecting part.

[0008] This application provides a heating assembly for use in household appliances. The heating assembly includes a power unit, a connecting unit, a heating plate, and a magnetic component.

[0009] The connecting part is connected to the power part, and the power part is used to drive the connecting part to rotate.

[0010] One of the heating plate and the magnetic component is connected to the connecting part and can rotate with the connecting part. The other of the heating plate and the magnetic component is movably connected to the connecting part through a connecting structure, and the connecting part can rotate relative to the connecting structure. That is to say, the rotation of the connecting part can drive one of the heating plate and the magnetic component to rotate, but the other of the heating plate and the magnetic component will not rotate with the connecting part.

[0011] Specifically, the heating plate is connected to the connecting part and can rotate with the connecting part, while the magnetic component is movably connected to the connecting part through a connecting structure. The power unit drives the connecting part to rotate, the heating plate rotates with the connecting part, but the magnetic component does not rotate with the connecting part.

[0012] Specifically, the magnetic component is connected to the connecting part and can rotate with the connecting part, while the heating plate is movably connected to the connecting part through a connecting structure. The power unit drives the connecting part to rotate, the magnetic component rotates with the connecting part, but the heating plate does not rotate with the connecting part.

[0013] It is understandable that when one of the heating plate and the magnetic component rotates with the connecting part, the movement of one of the heating plate and the magnet relative to the other causes a change in the alternating magnetic field acting on the heating plate, thereby generating eddy currents and heating the heating plate, achieving the purpose of heating the second body of the household appliance. The power unit, connecting part, heating plate, magnetic component, and connecting structure proposed in this application work together so that when one of the magnetic component and the heating plate rotates relative to the other, the changing rotating magnetic field cuts magnetic lines of force to generate eddy currents, causing the heating plate to heat up, which can meet the usage requirements of the household appliance in heating mode. Simultaneously, this design allows for real-time adjustment of the heating component's power by adjusting the rotation speed of the connecting part through the power unit, achieving stepless adjustment of the heating component's power and enabling constant temperature control. Compared to heating tube heating, it has the advantage of high temperature control accuracy, improving the temperature control precision of the household appliance and enhancing its performance and market competitiveness.

[0014] It is understandable that the other of the heating plate and magnetic component is movably connected to the connecting part through a connecting structure. That is, the connecting structure can not only connect and fix the other of the heating plate and magnetic component to the connecting part, but also meet the usage requirements that the other of the heating plate and magnetic component does not rotate with the connecting part.

[0015] The heating assembly described above according to this application may also have the following additional technical features:

[0016] In some technical solutions, optionally, the power unit can drive the connecting part to rotate in a first direction or a second direction; when the connecting part rotates in the first direction, one of the heating plate and the magnetic component can rotate with the connecting part in the first direction so that the heating plate heats up.

[0017] This technical solution defines the mating structure of the power unit, connecting part, heating plate and magnetic component.

[0018] The power unit can drive the connecting part to rotate in either a first direction or a second direction. Specifically, the power unit can drive the connecting part to rotate in either the first or second direction. This allows the connecting part to switch between rotating in the first and second directions. At least one of the heating plate and the magnetic component can rotate with the connecting part in the first direction, so that when either the heating plate or the magnetic component rotates with the connecting part in the first direction, the heating plate heats up, thereby heating the second body.

[0019] In some technical solutions, optionally, when the connecting part rotates in the second direction, one of the heating plate and the magnetic component does not rotate with the connecting part, and the heating plate does not heat up.

[0020] In this technical solution, the mating structure of the power unit, connecting part, heating plate and magnetic component is further defined.

[0021] When the power unit drives the connecting part to rotate in the first direction, one of the heating plate and the magnetic component can rotate along with the connecting part in the first direction, thereby changing the alternating magnetic field acting on the heating plate, causing eddy currents to be generated in the heating plate, which in turn causes the heating plate to heat up, thereby heating the second body, so that when food is contained in the second body, the food can be heated and stirred.

[0022] When the power unit drives the connecting part to rotate in the second direction, one of the heating plate and the magnetic component does not rotate with the connecting part. Consequently, the magnetic component and the heating plate cannot achieve magnetic field coupling, and the heating plate will not generate heat. That is, in the household appliance proposed in this application, the connecting part can rotate in both the first and second directions. Therefore, heating of the second body can be achieved when the connecting part rotates in the first direction, and stirring of the medium within the second body can be achieved when the connecting part rotates in the second direction. This design enables the household appliance to function as both a cold and hot beverage dispenser, further enriching the product's functionality and improving its performance and market competitiveness.

[0023] In some technical solutions, optionally, the heating assembly further includes: a first bracket, one of the heating plate and the magnetic component is disposed on the first bracket, the first bracket is rotatable with the connecting part in a first direction; wherein, in a second direction, the first bracket is movably engaged with the connecting part, and the first bracket does not rotate with the connecting part.

[0024] In this technical solution, the structure of the heating component is defined.

[0025] The heating assembly also includes a first bracket, on which one of the heating plate and the magnetic component is disposed. The first bracket serves as a mounting carrier for the heating plate and the magnetic component, and has the function of installing and fixing the heating plate and the magnetic component.

[0026] For example, the first bracket is positioned in a limiting engagement with the connecting portion along a first direction, and movably engaged with the connecting portion along a second direction. When the power unit drives the connecting portion to rotate along the first direction, it causes one of the first bracket and one of the heating plate and magnetic component mounted on the first bracket to rotate. This changes the alternating magnetic field acting on the heating plate, generating eddy currents and causing it to heat up, thus heating the second body. This allows for heating and stirring of food within the second body. Conversely, when the power unit drives the connecting portion to rotate along the second direction, the first bracket cannot rotate with the connecting portion, and therefore one of the heating plate and magnetic component does not rotate with the connecting portion, preventing the heating plate from heating up. This allows for stirring of food within the second body. In other words, the household appliance proposed in this application allows the connecting portion to rotate both along the first and second directions, enabling heating of the second body when the connecting portion rotates along the first direction and stirring of the medium within the second body when the connecting portion rotates along the second direction.

[0027] Optionally, along the first direction, the first bracket and the connecting part are in a limiting fit. For example, the first bracket and the connecting part are in a limiting fit along the first direction through a ratchet and pawl structure or a one-way bearing or other one-way transmission mechanism, so that the first bracket can rotate with the connecting part when the connecting part rotates along the first direction. The first bracket is in a movable fit with the connecting part along the second direction. For example, the first bracket and the connecting part are in a movable fit along the second direction through a ratchet and pawl structure or a one-way bearing or other one-way transmission mechanism, that is, when the connecting part rotates along the second direction, due to the characteristic that the ratchet and pawl structure or the one-way bearing can only release the moving part in one direction, the first bracket can rotate relative to the connecting part, that is, the first bracket does not rotate with the connecting part.

[0028] In some technical solutions, the heating assembly may optionally include: a one-way bearing sleeved on the connecting part, and the first bracket and the one-way bearing being engaged in a first direction, the one-way bearing being able to rotate with the connecting part along the first direction; a first limiting member disposed on the connecting part, the first limiting member being used to limit the one-way bearing along the length direction of the connecting part; wherein, when the connecting part rotates along the second direction, the connecting part is able to rotate relative to the first bracket through the one-way bearing.

[0029] In this technical solution, the structure of the heating component is defined.

[0030] The heating assembly also includes a one-way bearing and a first limiting element.

[0031] A one-way bearing is fitted onto the connecting part, and the first bracket and the one-way bearing are engaged in a limiting fit in the first direction. The first bracket is unidirectionally rotatably connected to the connecting part via the one-way bearing. Specifically, when the connecting part rotates in the first direction, the first bracket rotates with the connecting part via the one-way bearing. When the connecting part rotates in the second direction, the connecting part rotates relative to the first bracket via the one-way bearing, thereby preventing either the heating plate or the magnetic component from rotating with the connecting part.

[0032] By setting a first limiting member, the first limiting member limits the one-way bearing along the length direction of the connecting part, so that the one-way bearing cannot move along the length direction of the connecting part, thereby limiting the matching size between the one-way bearing and the connecting part, and thus limiting the matching size between the heating plate and the magnetic component, providing structural support for the effective heating of the heating plate.

[0033] In some technical solutions, the heating assembly may optionally include a second bracket, wherein one of the heating plate and the magnetic component is limited and engaged with the connecting portion via the second bracket.

[0034] In this technical solution, the heating assembly also includes a second bracket, which engages with the connecting part for limiting and positioning. One of the heating plate and the magnetic component is mounted on the second bracket, thereby supporting the heating plate and the magnetic component, improving the connection strength between the heating plate / magnetic component and the connecting part, and facilitating the installation of the heating plate / magnetic component. When the connecting part rotates in the first direction, the heating plate / magnetic component, driven by the second bracket, can rotate along the first direction with the connecting part, causing the heating plate to heat up.

[0035] Optionally, the second bracket and the connecting part form a limiting fit relationship. The second bracket and the connecting part can be fixedly connected, such as by welding or bonding. Based on the limiting fit relationship between the second bracket and the connecting part, the second bracket and the connecting part can also be detachably connected, such as by threaded connection, snap-fit, or connection through a two-way locking bearing. Optionally, the second bracket and the connecting part are detachably connected axially, allowing the second bracket to be disengaged from the connecting part.

[0036] In some technical solutions, the power unit may optionally be located on the second support.

[0037] In this technical solution, the power unit is located on the second bracket. One of the heating plate and the magnetic component shares the same bracket with the power unit, so that the second bracket can accommodate both the installation of the heating plate and the magnetic component and the installation of the power unit, thereby reducing the number of supporting components and lowering the height of the household appliance in the length direction of the connection.

[0038] In some technical solutions, optionally, along the length of the connecting part, one of the heating plate and the magnetic component is located at the upper or lower part of the second bracket, and the power unit is located at the lower or upper part of the second bracket; and / or the second bracket and the connecting part are limited and matched by any of the following methods: threaded connection, snap-fit, bidirectional locking bearing and welding; and / or the upper and lower parts of the second bracket are both provided with a first mounting groove, and one of the heating plate and the magnetic component and the power unit are respectively located in the first mounting groove.

[0039] In this technical solution, along the length of the connecting part, one of the heating plate and the magnetic component and the power unit are respectively located at the upper and lower parts of the second bracket, so as to facilitate the installation and disassembly of one of the heating plate and the magnetic component and the power unit.

[0040] Optionally, the second bracket and the connecting part can be connected by threads, snap-fit, bidirectional locking bearing, or welding.

[0041] Optionally, the upper and lower parts of the second bracket are respectively provided with first mounting grooves, and one of the heating plate and magnetic component and the power component are respectively provided in the first mounting grooves on both sides of the second bracket, which can reduce the height of the household appliance in the length direction of the connection part.

[0042] In some technical solutions, optionally, when the connecting part rotates in the second direction, one of the heating plate and the magnetic component rotates with the connecting part via the second bracket, so that the heating plate heats up.

[0043] In this technical solution, the mating structure of the power unit, connecting part, heating plate and magnetic component is further defined.

[0044] When the power unit drives the connecting part to rotate in the first direction, one of the heating plate and the magnetic component can rotate with the connecting part in the first direction, thereby changing the alternating magnetic field acting on the heating plate, causing eddy currents to be generated in the heating plate, which in turn causes the heating plate to heat up, thus achieving heating of the second body.

[0045] When the power unit drives the connecting part to rotate in the second direction, one of the heating plate and the magnetic component can rotate with the connecting part in the second direction, thereby changing the alternating magnetic field acting on the heating plate, causing eddy currents to be generated in the heating plate, which in turn causes the heating plate to heat up, thus achieving heating of the second body.

[0046] Specifically, when the connecting part rotates in the first direction, one of the heating plate and the magnetic component can rotate along with the connecting part in the first direction under the drive of the second bracket, so that the heating plate heats up.

[0047] Specifically, when the connecting part rotates in the second direction, one of the heating plate and the magnetic component can rotate along with the connecting part in the second direction under the drive of the second bracket, so that the heating plate heats up.

[0048] In some technical solutions, optionally, at least a portion of the heating plate is located above the magnetic element.

[0049] In this technical solution, the mating structure of the heating plate and the magnetic component is defined.

[0050] At least a portion of the heating plate is located above the magnetic element. That is, a portion of the heating plate is located above the magnetic element, or the entire heating plate is located above the magnetic element.

[0051] This arrangement keeps the heating plate away from the first body to avoid heating the first body and affecting the operation of the electrical components inside it. While ensuring the heating effect of the heating component, it also ensures the operating temperature of other components in the household appliance, providing structural support for ensuring the performance of the household appliance.

[0052] In some technical solutions, optionally, the other of the heating plate and the magnetic component is arranged around the connecting portion and spaced apart from the connecting portion; the other of the heating plate and the magnetic component is provided with a second mounting groove, the opening of the second mounting groove facing the power unit; the connecting structure includes a first bearing, the first bearing is located in the second mounting groove; the first bearing is sleeved on the connecting portion, and the first bearing connects the other of the heating plate and the magnetic component.

[0053] In this technical solution, the other of the heating plate and the magnetic component is arranged around the connecting portion and spaced apart from it. That is, the other of the heating plate and the magnetic component is fitted onto the connecting portion, and there is a gap between the other of the heating plate and the magnetic component and the connecting portion. In this way, when the connecting portion rotates, the other of the heating plate and the magnetic component does not rotate with the connecting portion.

[0054] The connecting structure includes a first bearing.

[0055] The first bearing is located within the second mounting groove and is sleeved on the connecting part. The first bearing connects the heating plate and the other of the magnetic components. Thus, when the connecting part rotates, the other of the heating plate and magnetic components will not rotate with the connecting part. Simultaneously, the first bearing also serves to connect the other of the heating plate and magnetic components and the connecting part.

[0056] In some technical solutions, the connecting structure may optionally include a seal located in the second mounting groove; the groove walls of the first bearing and the second mounting groove are connected by the seal; or the seal is connected between the connecting part and the groove wall of the second mounting groove, and the seal is located between the bottom of the first bearing and the second mounting groove.

[0057] In this technical solution, the connection structure also includes a seal, which is located in the second mounting groove.

[0058] The walls of the first bearing and the second mounting groove are connected by a seal.

[0059] Alternatively, the seal is connected between the connecting part and the wall of the second mounting groove, and the seal is located between the bottom of the first bearing and the second mounting groove.

[0060] The first bearing and the seal work together to connect the heating plate and the magnetic component, and the seal also acts as a barrier against water and dirt in the environment, thus ensuring the waterproof performance of the household appliance.

[0061] In some technical solutions, the connecting structure may optionally include: an oil seal, connected between the other of the heating plate and the magnetic component and the connecting portion; and / or a second limiting member, disposed on the other of the heating plate and the magnetic component, the second limiting member being used to limit the first bearing along the length direction of the connecting portion.

[0062] In this technical solution, the composition of the connection structure is defined.

[0063] The connection structure also includes an oil seal and / or a second limiting element.

[0064] When the connection structure also includes an oil seal, the oil seal is connected between the heating plate and the other of the magnetic components and the connection part. The oil seal can block water, dirt, etc. in the environment, and prevent water, dirt, etc. from entering the heating component.

[0065] When the connecting structure also includes a second limiting member, the second limiting member limits the first bearing along the length direction of the connecting part, so that the first bearing cannot move along the length direction of the connecting part, thereby limiting the other of the heating plate and the magnetic component, and thus limiting the mating dimensions of the heating plate and the magnetic component, providing structural support for the effective heating of the heating plate.

[0066] In some technical solutions, optionally, when the connecting structure includes a second limiting member, the second limiting member includes: a washer, the washer being sleeved on the connecting portion and spaced apart from the connecting portion; a retaining ring, the retaining ring being connected to the other of the heating plate and the magnetic component, and the washer abutting against the side of the first bearing facing the power portion and between the retaining ring.

[0067] In this technical solution, when the connecting structure includes a second limiting member, the structure of the second limiting member is defined.

[0068] The second limiting component includes a washer and a retaining ring.

[0069] The washer is fitted onto the connecting part and spaced apart from the connecting part. That is, the washer is arranged around the connecting part, and there is a gap between the washer and the connecting part.

[0070] The other of the heating plate and magnetic component is connected to the retaining ring, and the washer abuts between the first bearing on the side facing the power unit and the retaining ring.

[0071] In other words, the snap ring and the washer work together to limit the first bearing along the length of the connection, so that the first bearing cannot move along the length of the connection, thereby limiting the other of the heating plate and the magnetic component, and thus limiting the mating dimensions of the heating plate and the magnetic component, providing structural support for the effective heating of the heating plate.

[0072] In some technical solutions, the connecting structure may optionally include a second bearing and a third bracket. The second bearing is connected between the connecting part and the third bracket, and the third bracket is located between the other of the heating plate and the magnetic component and the power part. The other of the heating plate and the magnetic component is connected to the third bracket and encloses the mounting cavity. One of the heating plate and the magnetic component is located inside the mounting cavity, and the other of the heating plate and the magnetic component is used for mounting and fixing the power part, the connecting part, and the connecting structure.

[0073] In this technical solution, the connecting structure also includes a second bearing and a third bracket.

[0074] The second bearing connects the connecting part and the third bracket. Specifically, the second bearing is sleeved on the connecting part, with its inner ring connected to the connecting part and its outer ring connected to the third bracket. The inner ring of the second bearing can rotate relative to its outer ring. Thus, when the connecting part rotates, the third bracket will not rotate with the connecting part.

[0075] The third bracket is located between the other of the heating plate and the magnetic component and the power unit. The other of the heating plate and the magnetic component is connected to the third bracket and encloses the mounting cavity, which serves to accommodate one of the heating plate and the magnetic component.

[0076] When installing the heating assembly, the other of the heating plate and the magnetic component is connected to the second body. That is, the other of the heating plate and the magnetic component is used for the installation and fixation of the power unit, the connecting part, and the connecting structure.

[0077] By defining the cooperation structure between the heating plate and the magnetic component, the second bearing, the third bracket, and the connecting part, dynamic balance can be ensured when the power unit drives the connecting part to rotate, reducing the amount of shaking. This helps to reduce the operating noise of household appliances. At the same time, because this structure reduces the amount of shaking, it can ensure the cooperation position between the heating plate and the magnetic component, which helps to improve the stability and reliability of the heating plate.

[0078] For example, the other of the heating plate and the magnetic component is provided with a second mounting groove, the opening of the second mounting groove facing the third bracket.

[0079] In some technical solutions, the heating plate may optionally include any one or a combination of the following: an aluminum plate, an iron plate, or an aluminum-iron composite plate.

[0080] In this technical solution, the heating plate includes any one or a combination of the following: an aluminum plate, an iron plate, or an aluminum-iron composite plate. The heating plate has good thermal conductivity, which can improve the heating effect on the second body.

[0081] In some technical solutions, the magnetic component may optionally be ring-shaped; or there may be multiple magnetic components arranged circumferentially along the connection portion.

[0082] In this technical solution, the magnetic component is ring-shaped, which allows it to surround the connecting part to facilitate its installation. Furthermore, making the magnetic component ring-shaped can shorten the magnetic circuit, increase the magnetic flux density, and thus improve the starting torque.

[0083] Alternatively, there can be multiple magnetic components distributed circumferentially along the connection. This arrangement can reduce manufacturing costs.

[0084] In some technical solutions, optionally, when there are multiple magnetic components, the multiple magnetic components include multiple N poles and multiple S poles, and the number of pole pairs of the magnetic components is greater than or equal to 4 pairs; and / or the heating assembly further includes a first magnetic conductive component, which is disposed between two adjacent magnetic components.

[0085] In this technical solution, when there are multiple magnetic components, the number of pole pairs of the magnetic components is greater than or equal to 4 pairs, which can improve the heating power.

[0086] The heating assembly also includes a first magnetic conductor, which is disposed between two adjacent magnetic components. This allows the magnetic flux density of the magnetic components and the power unit to be more concentrated, which is beneficial to improving rotation efficiency and heating efficiency.

[0087] In some technical solutions, the power unit may optionally include: a rotor core, the rotor core having a connecting hole, and a connecting part passing through the connecting hole; and multiple permanent magnets disposed on the rotor core, the multiple permanent magnets being arranged circumferentially around the connecting hole.

[0088] In this technical solution, the structure of the power unit is defined.

[0089] The power unit includes a rotor core and multiple permanent magnets. The rotor core has connecting holes, through which the connecting parts pass to meet the requirements of the power unit driving the connecting parts to rotate.

[0090] Multiple permanent magnets are located on the rotor core, and the multiple permanent magnets are arranged circumferentially around the connecting hole.

[0091] The power unit is used to cooperate with the stator, and the stator drives the connecting part to rotate through the rotor.

[0092] In some technical solutions, optionally, the heating assembly further includes: a stator, arranged along the axial direction of the rotor core, the stator being spaced apart on the side of the power unit away from the connecting structure, the stator being used to drive the connecting unit to rotate through the power unit; the stator includes a stator core, windings and winding supports, the windings being wound around the stator core through the winding supports.

[0093] In this technical solution, the structure of the heating component is defined.

[0094] The heating assembly also includes a stator, which is arranged at intervals along the axial direction of the rotor core on the side of the power unit away from the connecting structure.

[0095] For example, a stator is disposed on the first body of the household appliance, and a power unit is disposed on the second body. The stator can drive the power unit to rotate, thereby causing the power unit to drive the connecting part to rotate. Furthermore, the power unit is located on one side of the stator along the axial direction. Through the principle of axial magnetic flux coupling, the power unit and the stator are separated, so that the second body and the first body do not need to transmit power through a connecting shaft. This arrangement also reduces the axial thickness of the stator and the power unit, as well as the overall weight, thus reducing the overall height and weight of the household appliance, facilitating its storage and transportation. Users can store the first body with the stator and the second body with the power unit separately, improving storage and carrying convenience. The household appliance proposed in this application can achieve both the processing of the medium inside the second body and the heating function through the rotation of the same connecting part, improving the utilization rate of the connecting part. Moreover, it eliminates the need for electrical components on the second body, enabling the entire second body to be cleaned, thus improving the convenience of cleaning the second body.

[0096] In addition, by using the principle of axial magnetic flux coupling, the power unit and the stator are set up separately, eliminating the need for a connecting shaft to pass through the second body to transmit power, thus improving the sealing performance of the second body. It also eliminates the need for a coupling to connect the shafts, thereby reducing the noise when the household appliance is working.

[0097] In some technical solutions, the heating assembly may optionally include a second magnetic conductor and a third magnetic conductor, wherein the second magnetic conductor is located on the side of the magnetic component facing the power unit, and the third magnetic conductor is located on the side of the permanent magnet facing the magnetic component.

[0098] In this technical solution, the heating component also includes a second magnetic conductive element and a third magnetic conductive element.

[0099] The second magnetic guide element is located on the side of the magnetic component facing the power unit, and the third magnetic guide element is located on the side of the permanent magnet facing the magnetic component. By setting the second and third magnetic guide elements, the magnetic flux density of the magnetic component and the power unit can be more concentrated, thereby improving rotational efficiency and heating efficiency.

[0100] In some technical solutions, the heating assembly may optionally include: a cutting tool and a cutting tool connecting part; or a stirring component and a stirring component connecting part; or a fan blade and a fan blade connecting part.

[0101] In this technical solution, the heating assembly also includes blades, a stirring element, or a fan blade. The rotating blades process the food. The rotating stirring element agitates the ingredients. The rotating fan blades deliver airflow.

[0102] The cutting tool, stirring component, and fan blades are collectively referred to as the processing unit. This application achieves both the processing of the medium within the second body and the heating function through the rotation of a single connecting part, thus improving the utilization rate of the connecting part. In other words, one of the heating plate and magnetic component shares the same power unit and connecting part with the processing unit, and the connecting part serves as the mounting carrier for either the heating plate or the magnetic component. This eliminates the need for additional components to install and fix either the heating plate or the magnetic component, allowing the heating assembly to not only heat but also process the medium within the second body. This enriches the functions of the heating assembly, reduces the number of components, helps lower production costs, reduces the overall size of the heating assembly, and improves its performance and market competitiveness.

[0103] Household appliances include any one of the following: food processor, rice cooker, and fan.

[0104] Specifically, in the case of a household appliance including a food processor, the first body includes a base assembly, and the second body includes a cup assembly. A blade and a connecting part are connected. The cup assembly is placed on the base assembly. Through the interaction between the stator and the power unit, the blade rotates, thereby processing the food inside the cup assembly. Simultaneously, the power unit is fitted onto the connecting part to drive the blade to rotate. One of a magnetic component or a heating plate is fitted onto the connecting part, enabling the connecting part to drive either the magnetic component or the heating plate to rotate. The power unit, heating plate, and magnetic component are located on the same side of the blade.

[0105] Specifically, in the case of a household appliance including a rice cooker, the first body includes a first pot body, the second body includes a second pot body, a stirring member and a connecting part are connected, the second pot body is disposed inside the first pot body, and the food inside the second pot body is heated by a heating plate. At least a portion of the stirring member extends into the second pot body to stir the food inside the second pot body, thereby improving the uniformity of heating of the food inside the second pot body and preventing scorching. The power unit, heating plate and magnetic component are located on the same side of the stirring member.

[0106] Specifically, in the case of household appliances including fans, the fan head and fan base can be separated, facilitating the cleaning of the fan head. Simultaneously, when the fan head is mounted on the fan base, the stator inside the fan base drives the power unit inside the fan head to rotate, which in turn drives the fan blades to rotate via the connecting part, achieving the air delivery function. The power unit, heating plate, and magnetic component are located on the same side of the fan blades.

[0107] The second aspect of this application provides a household appliance comprising: a heating component as described in the first aspect.

[0108] The household appliance provided in this application includes the heating component as described in the first aspect, and therefore has all the beneficial effects of the aforementioned heating component, which will not be described in detail here.

[0109] In some technical solutions, the household appliance may optionally include: a first body, wherein the stator of the heating component is disposed on the first body; and a second body, wherein the second body can be installed on the first body, and the power unit, connecting part, heating plate, magnetic component and connecting structure are all disposed on the second body.

[0110] In this technical solution, the household appliance also includes a first body and a second body.

[0111] The stator of the heating assembly is mounted on the first body via a fixed bracket. The power unit, connecting part, heating plate, magnetic components, and connecting structure are all mounted on the second body. The stator can drive the power unit to rotate, which in turn drives the connecting part to rotate. Furthermore, the power unit is located on one side of the stator along the axial direction. Through the principle of axial magnetic flux coupling, the power unit and the stator are separated, so that the second body and the first body do not need to transmit power through a connecting shaft. At the same time, this arrangement can also reduce the thickness of the stator and the power unit along the axial direction, as well as the overall weight, thereby helping to reduce the overall height and weight of the household appliance, making it easier to store and transport. When storing, the user can store the first body with the stator and the second body with the power unit separately, improving the convenience of storage and carrying.

[0112] In this configuration, one of the heating plate and the magnetic component is connected to the second body; that is, the other of the heating plate and the magnetic component is used for the installation and fixation of the power unit, the connecting part, and the connecting structure. The power unit, the connecting part, and the connecting structure are connected to the second body through the other of the heating plate and the magnetic component. This arrangement helps to reduce the amount of shaking, ensures the proper alignment of the heating plate and the magnetic component, reduces operating noise, and improves the stability and reliability of the heating plate.

[0113] The axial magnetic flux coupling principle separates the power unit and the stator, reducing their axial thickness and weight. This, in turn, helps reduce the overall height and weight of the appliance, facilitating storage and transportation. Furthermore, by separating the stator and power unit through axial magnetic flux coupling, the need for a connecting shaft passing through the second body for power transmission is eliminated, improving the sealing performance of the second body. The absence of a coupling between the shafts also reduces noise during operation.

[0114] In some technical solutions, optionally, when the heating component includes a blade, the household appliance includes a food processor, the first body includes a base assembly, the second body includes a cup assembly, the cup assembly can be mounted on the base assembly, and the blade is located inside the cup assembly; when the heating component includes a stirring member, the household appliance includes a rice cooker, the first body includes a first pot body, the second body includes a second pot body, the second pot body is disposed inside the first pot body, at least a portion of the stirring member extends into the second pot body, and the heating plate is located at the bottom of the second pot body; when the heating component includes fan blades, the household appliance includes a fan, the first body includes a fan base, the second body includes a fan head, the fan head can be mounted on the fan base, and the fan blades are disposed on the fan head and can rotate relative to the fan head.

[0115] In this technical solution, the household appliance includes any one of a food processor, a rice cooker, and a fan.

[0116] Specifically, in the case of a household appliance including a food processor, the first body includes a base assembly, the second body includes a cup assembly, and a blade connecting part. The cup assembly is placed on the base assembly. Through the interaction between the stator and the power unit, the blade rotates, thereby processing the food inside the cup assembly. At the same time, the power unit is sleeved on the connecting part to drive the blade to rotate. One of the magnetic component and the heating plate is sleeved on the connecting part, so that the connecting part can drive the magnetic component or the heating plate to rotate.

[0117] Specifically, in the case of a household appliance including a rice cooker, the first body includes a first pot body, the second body includes a second pot body, a stirring element is connected to the connecting part, the second pot body is disposed inside the first pot body, the food inside the second pot body is heated by a heating plate, at least a part of the stirring element extends into the second pot body to stir the food inside the second pot body, thereby improving the uniformity of heating of the food inside the second pot body and preventing the food from burning.

[0118] Specifically, in the case of household appliances including fans, the fan head and fan base can be separated, which facilitates the cleaning of the fan head. At the same time, when the fan head is installed in the fan base, the stator in the fan base drives the power unit in the fan head to rotate, and the power unit drives the fan blades to rotate through the connecting part to realize the air delivery function.

Detailed Implementation

[0132] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0133] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0134] The following reference Figures 1 to 9 The present application describes heating assembly 12 and household appliance 1 according to some embodiments.

[0135] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a heating assembly 12 according to some embodiments of this application is used in a household appliance 1. The heating assembly 12 includes a power unit 100, a connecting part 220, a heating plate 300, and a magnetic element 400.

[0136] The connecting part 220 is connected to the power unit 100.

[0137] The power unit 100 is used to drive the connecting part 220 to rotate.

[0138] One of the heating plate 300 and the magnetic component 400 is connected to the connecting part 220 and can rotate with the connecting part 220.

[0139] The other of the heating plate 300 and the magnetic component 400 is movably connected to the connecting part 220 via the connecting structure 500.

[0140] The connecting part 220 is rotatable relative to the connecting structure 500.

[0141] When either the heating plate 300 or the magnetic component 400 rotates with the connecting part 220, the heating plate 300 can be heated.

[0142] The present application provides a heating component 12 for use in a household appliance 1. The heating component 12 includes a power unit 100, a connecting part 220, a heating plate 300, and a magnetic component 400.

[0143] The connecting part 220 is connected to the power part 100, and the power part 100 is used to drive the connecting part 220 to rotate.

[0144] One of the heating plate 300 and the magnetic component 400 is connected to the connecting part 220 and can rotate with the connecting part 220. The other of the heating plate 300 and the magnetic component 400 is movably connected to the connecting part 220 through the connecting structure 500, and the connecting part 220 can rotate relative to the connecting structure 500. That is to say, the rotation of the connecting part 220 can drive one of the heating plate 300 and the magnetic component 400 to rotate, but the other of the heating plate 300 and the magnetic component 400 will not rotate with the connecting part 220.

[0145] Specifically, the heating plate 300 is connected to the connecting part 220 and can rotate with the connecting part 220, while the magnetic component 400 is movably connected to the connecting part 220 through the connecting structure 500. The power unit 100 drives the connecting part 220 to rotate, the heating plate 300 rotates with the connecting part 220, but the magnetic component 400 does not rotate with the connecting part 220.

[0146] Specifically, the magnetic component 400 is connected to the connecting part 220 and can rotate with the connecting part 220, while the heating plate 300 is movably connected to the connecting part 220 via the connecting structure 500. The power unit 100 drives the connecting part 220 to rotate, the magnetic component 400 rotates with the connecting part 220, but the heating plate 300 does not rotate with the connecting part 220.

[0147] It is understandable that when one of the heating plate 300 and the magnetic component 400 rotates with the connecting part 220, the heating plate 300 and the magnet move relative to the other, causing a change in the alternating magnetic field acting on the heating plate 300. This generates eddy currents in the heating plate 300, causing it to heat up and thus heating the second body 16 of the household appliance 1. The power unit 100, connecting part 220, heating plate 300, magnetic component 400, and connecting structure 500 proposed in this application work together so that when one of the magnetic component 400 and the heating plate 300 rotates relative to the other, the changing rotating magnetic field cuts magnetic lines of force to generate eddy currents, causing the heating plate 300 to heat up, meeting the usage requirements of the household appliance 1 in heating mode. Simultaneously, this arrangement allows the power of the heating component 12 to be adjusted in real time by regulating the rotation speed of the connecting part 220 via the power unit 100. Compared to heating tube heating, this offers the advantage of higher temperature control accuracy, improving the temperature control precision of the household appliance 1 and enhancing its performance and market competitiveness.

[0148] It is understandable that the other of the heating plate 300 and the magnetic component 400 is movably connected to the connecting part 220 through the connecting structure 500. That is, the connecting structure 500 can not only connect and fix the other of the heating plate 300 and the magnetic component 400 to the connecting part 220, but also meet the usage requirement that the other of the heating plate 300 and the magnetic component 400 does not rotate with the connecting part 220.

[0149] For example, the connecting part 220 includes a pivot.

[0150] This embodiment provides a heating assembly 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: the power unit 100 can drive the connecting part 220 to rotate in a first direction or a second direction.

[0151] When the connecting part 220 rotates in the first direction, one of the heating plate 300 and the magnetic element 400 can rotate along the first direction with the connecting part 220, so that the heating plate 300 heats up.

[0152] In this embodiment, the mating structure of the power unit 100, the connecting part 220, the heating plate 300, and the magnetic element 400 is defined.

[0153] The power unit 100 can drive the connecting part 220 to rotate in either a first direction or a second direction. Specifically, the power unit 100 can drive the connecting part 220 to rotate in either the first or second direction. This allows the connecting part 220 to switch between rotating in the first and second directions. At least one of the heating plate 300 and the magnetic component 400 can rotate with the connecting part 220 in the first direction, causing the heating plate 300 to heat up when it rotates with the connecting part 220 in the first direction, thereby heating the second body 16.

[0154] For example, one of the first direction and the second direction is clockwise, and the other of the first direction and the second direction is counterclockwise.

[0155] For example, when the connecting part 220 rotates in the second direction, one of the heating plate 300 and the magnetic element 400 rotates with the connecting part 220.

[0156] For example, when the connecting part 220 rotates in the second direction, one of the heating plate 300 and the magnetic element 400 does not rotate with the connecting part 220.

[0157] This embodiment provides a heating assembly 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: when the connecting part 220 rotates in the second direction, one of the heating plate 300 and the magnetic component 400 does not rotate with the connecting part 220, and the heating plate 300 does not heat up.

[0158] In this embodiment, the mating structure of the power unit 100, the connecting part 220, the heating plate 300, and the magnetic component 400 is further defined.

[0159] When the power unit 100 drives the connecting part 220 to rotate in the first direction, one of the heating plate 300 and the magnetic component 400 can rotate along the first direction with the connecting part 220. This causes the alternating magnetic field acting on the heating plate 300 to change, resulting in eddy currents in the heating plate 300. This causes the heating plate 300 to heat up, thereby heating the second body 16. This allows for the heating and stirring of food when food is contained in the second body 16.

[0160] When the power unit 100 drives the connecting part 220 to rotate in the second direction, one of the heating plate 300 and the magnetic component 400 does not rotate with the connecting part 220. Consequently, the magnetic component 400 and the heating plate 300 cannot achieve magnetic field coupling, and the heating plate 300 will not heat up. This allows for stirring of the food when it is contained within the second body 16. In other words, the household appliance 1 proposed in this application allows the connecting part 220 to rotate in both the first and second directions. This enables heating of the second body 16 when the connecting part 220 rotates in the first direction and stirring of the medium within the second body 16 when the connecting part 220 rotates in the second direction. This configuration allows the household appliance 1 to function as both a cold and hot beverage dispenser, further enriching the product's functionality and improving its performance and market competitiveness.

[0161] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, the heating assembly 12 also includes a first bracket 600.

[0162] One of the heating plate 300 and the magnetic component 400 is disposed on the first support 600.

[0163] The first bracket 600 can rotate along the first direction with the connecting part 220.

[0164] In the second direction, the first bracket 600 is movably engaged with the connecting part 220, and the first bracket 600 does not rotate with the connecting part 220.

[0165] In this embodiment, the structure of the heating component 12 is defined.

[0166] The heating assembly 12 also includes a first bracket 600, and one of the heating plate 300 and the magnetic component 400 is disposed on the first bracket 600. The first bracket 600 serves as a mounting carrier for one of the heating plate 300 and the magnetic component 400, and has the function of mounting and fixing one of the heating plate 300 and the magnetic component 400.

[0167] For example, the first support 600 is limited to the connecting part 220 along the first direction, and the first support 600 is movably engaged with the connecting part 220 along the second direction. When the power unit 100 drives the connecting part 220 to rotate along the first direction, it drives one of the first support 600 and the heating plate 300 and magnetic component 400 disposed on the first support 600 to rotate. The alternating magnetic field acting on the heating plate 300 changes, causing the heating plate 300 to generate eddy currents, which causes the heating plate 300 to heat up and realize the heating of the second body 16. This allows for the heating and stirring of food when food is contained in the second body 16. When the power unit 100 drives the connecting part 220 to rotate in the second direction, the first bracket 600 cannot rotate with the connecting part 220. Consequently, one of the heating plate 300 and the magnetic component 400 does not rotate with the connecting part 220, so that the heating plate 300 cannot generate heat. This allows for stirring of the food when food is contained in the second body 16. In other words, in the household appliance 1 proposed in this application, the connecting part 220 can rotate in both the first and second directions. Thus, the second body 16 can be heated when the connecting part 220 rotates in the first direction, and the medium inside the second body 16 can be stirred when the connecting part 220 rotates in the second direction.

[0168] Optionally, along the first direction, the first bracket 600 and the connecting part 220 are in a limiting engagement. For example, the first bracket 600 and the connecting part 220 are in a limiting engagement along the first direction through a ratchet and pawl structure or a one-way bearing 700 and other one-way transmission mechanisms, so that the first bracket 600 can rotate with the connecting part 220 when the connecting part 220 rotates along the first direction. The first bracket 600 is in a movable engagement with the connecting part 220 along the second direction. For example, the first bracket 600 and the connecting part 220 are in a movable engagement along the second direction through a ratchet and pawl structure or a one-way bearing 700 and other one-way transmission mechanisms, that is, when the connecting part 220 rotates along the second direction, due to the characteristic that the ratchet and pawl structure or the one-way bearing 700 can only release the moving part in one direction, the first bracket 600 can rotate relative to the connecting part 220, that is, the first bracket 600 does not rotate with the connecting part 220.

[0169] Of course, the unidirectional transmission component can also have other structures, which are not specifically limited here.

[0170] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, the heating assembly 12 also includes a one-way bearing 700 and a first limiting member 800.

[0171] One-way bearing 700 is sleeved on connecting part 220, and first bracket 600 and one-way bearing 700 are engaged in upper limit cooperation in the first direction.

[0172] The one-way bearing 700 can rotate along the first direction with the connecting part 220.

[0173] The first limiting member 800 is provided at the connecting part 220.

[0174] The first limiting member 800 is used to limit the one-way bearing 700 along the length direction of the connecting part 220.

[0175] When the connecting part 220 rotates in the second direction, the connecting part 220 can rotate relative to the first bracket 600 via the one-way bearing 700.

[0176] In this embodiment, the structure of the heating component 12 is defined.

[0177] The heating assembly 12 also includes a one-way bearing 700 and a first limiting member 800.

[0178] A one-way bearing 700 is sleeved on the connecting portion 220. The first bracket 600 and the one-way bearing 700 are engaged in a limiting fit in the first direction. The first bracket 600 is unidirectionally rotatably connected to the connecting portion 220 via the one-way bearing 700. Specifically, when the connecting portion 220 rotates in the first direction, the first bracket 600 rotates with the connecting portion 220 via the one-way bearing 700. When the connecting portion 220 rotates in the second direction, the connecting portion 220 rotates relative to the first bracket 600 via the one-way bearing 700, thereby preventing either the heating plate 300 or the magnetic component 400 from rotating with the connecting portion 220.

[0179] By setting the first limiting member 800, the first limiting member 800 limits the one-way bearing 700 along the length direction of the connecting part 220, so that the one-way bearing 700 cannot move along the length direction of the connecting part 220, thereby limiting the mating size of the one-way bearing 700 and the connecting part 220, and thus limiting the mating size of the heating plate 300 and the magnetic component 400, providing structural support for the effective heating of the heating plate 300.

[0180] For example, the first limiting member 800 includes a retaining ring.

[0181] For example, the first bracket 600 is provided with a positioning groove, the one-way bearing 700 is provided in the positioning groove, the first limiting member 800 is located at the opening of the positioning groove, and the first limiting member 800 abuts against the one-way bearing 700.

[0182] This embodiment provides a heating assembly 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: when the connecting part 220 rotates in the second direction, one of the heating plate 300 and the magnetic component 400 rotates with the connecting part 220 through the second bracket 900, so that the heating plate 300 heats up.

[0183] In this embodiment, the mating structure of the power unit 100, the connecting part 220, the heating plate 300, and the magnetic component 400 is further defined.

[0184] When the power unit 100 drives the connecting part 220 to rotate in the first direction, one of the heating plate 300 and the magnetic component 400 can rotate along the first direction with the connecting part 220. This causes the alternating magnetic field acting on the heating plate 300 to change, resulting in eddy currents in the heating plate 300. This causes the heating plate 300 to heat up, thereby heating the second body 16. This allows for the heating and stirring of food when food is contained in the second body 16.

[0185] When the power unit 100 drives the connecting part 220 to rotate in the second direction, one of the heating plate 300 and the magnetic component 400 can rotate in the second direction along with the connecting part 220. This causes the alternating magnetic field acting on the heating plate 300 to change, resulting in eddy currents in the heating plate 300. This causes the heating plate 300 to heat up, thereby heating the second body 16. This allows for the heating and stirring of food when food is contained in the second body 16.

[0186] For example, one of the heating plate 300 and the magnetic element 400 is limited and engaged with the connecting portion 220 in both the first and second directions, so that when the connecting portion 220 rotates in the first direction or when the connecting portion 220 rotates in the second direction, the magnetic element 400 can rotate with the connecting portion 220 to make the heating plate 300 heat up.

[0187] For example, one of the heating plate 300 and the magnetic component 400 is limited and engaged with the connecting portion 220 in both the first and second directions. In this way, when the connecting portion 220 rotates in the first direction, the heating plate 300 can rotate with the connecting portion 220 in the first direction, and when the connecting portion 220 rotates in the second direction, the heating plate 300 can rotate with the connecting portion 220 in the second direction, so that the heating plate 300 can be heated regardless of whether the connecting portion 220 rotates in the first or second direction.

[0188] In this configuration, one of the heating plate 300 and the magnetic component 400 is positioned and engaged with the connecting portion 220 along both the first and second directions. Optionally, the connection between the heating plate 300 and the magnetic component 400 and the connecting portion 220 can be fixed, such as by welding or bonding. Alternatively, based on the positioning and engaging relationship between the heating plate 300 and the magnetic component 400 and the connecting portion 220, the connection can also be detachable, such as by threaded connection, snap-fit, or connection via a bidirectional locking bearing.

[0189] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 5 and Figure 6 As shown, the heating assembly 12 also includes a second bracket 900.

[0190] One of the heating plate 300 and the magnetic component 400 is positioned and engaged with the connecting part 220 via the second bracket 900.

[0191] In this embodiment, the heating assembly 12 further includes a second bracket 900, which is mutually restrictive with the connecting portion 220. One of the heating plate 300 and the magnetic component 400 is disposed on the second bracket 900, thereby supporting the heating plate 300 and the magnetic component 400, improving the connection strength between the heating plate 300 / magnetic component 400 and the connecting portion 220, and facilitating the installation of the heating plate 300 / magnetic component 400. When the connecting portion 220 rotates in the first direction, the heating plate 300 / magnetic component 400 can rotate along with the connecting portion 220 in the first direction under the drive of the second bracket 900, so that the heating plate 300 generates heat.

[0192] Optionally, the second bracket 900 and the connecting portion 220 form a limiting fit relationship. The second bracket 900 and the connecting portion 220 can be fixedly connected, such as by welding or bonding. Based on the limiting fit relationship between the second bracket 900 and the connecting portion 220, the second bracket 900 and the connecting portion 220 can also be detachably connected, such as by threaded connection, snap-fit, or connection via a two-way locking bearing. Optionally, the second bracket 900 and the connecting portion 220 are detachably connected axially, allowing the second bracket 900 to detach from the connecting portion 220.

[0193] In some other embodiments, when the connecting part 220 rotates in the second direction, one of the heating plate 300 and the magnetic element 400 can rotate along the second direction with the connecting part 220 under the drive of the second bracket 900, so that the heating plate heats up.

[0194] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 5 and Figure 6 As shown, the power unit 100 is provided on the second bracket 900, and the power unit 100 is stacked on one side of the heating plate 300 and the magnetic component 400.

[0195] In this embodiment, the positional relationship between one of the heating plate 300 and the magnetic element 400 and the power unit 100 is defined.

[0196] The power unit 100 is stacked on one side of either the heating plate 300 or the magnetic component 400. That is, the power unit 100 is stacked on one side of the heating plate 300, or the power unit 100 is stacked on one side of the magnetic component 400.

[0197] For example, the power unit 100 is located above one of the heating plate 300 and the magnetic element 400.

[0198] For example, one of the heating plate 300 and the magnetic element 400 is located above the power unit 100.

[0199] This configuration ensures the proper fit between the heating plate 300 and the magnetic component 400 and the power unit 100. The second bracket 900 not only serves to install and fix the heating plate 300 and the magnetic component 400, but also to install and fix the power unit 100, providing structural support for the power unit 100 to effectively drive the movement of the heating plate 300 and the magnetic component 400.

[0201] In this embodiment, the power unit 100 is mounted on the second bracket 900. One of the heating plate 300 and the magnetic component 400 shares the same bracket with the power unit 100, so that the second bracket 900 can be used to install both the heating plate 300 and the magnetic component 400 and the power unit 100. This reduces the number of supporting components and lowers the height of the household appliance 1 in the length direction of the connecting part 220.

[0202] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 8 As shown, along the length of the connecting portion 220, one of the heating plate 300 and the magnetic component 400 is located on the upper or lower part of the second bracket 900, and the power unit 100 is located on the lower or upper part of the second bracket 900; and / or the second bracket 900 and the connecting portion 220 are limited and engaged by any of the following methods: threaded connection, snap-fit, bidirectional locking bearing and welding; and / or the upper and lower parts of the second bracket 900 are each provided with a first mounting groove 910, and one of the heating plate 300 and the magnetic component 400 and the power unit 100 are respectively located in the first mounting groove 910.

[0203] In this embodiment, along the length of the connecting portion 220, one of the heating plate 300 and the magnetic component 400 and the power unit 100 are respectively disposed on the upper and lower parts of the second bracket 900, so as to facilitate the installation and removal of one of the heating plate 300 and the magnetic component 400 and the power unit 100.

[0204] Optionally, the second bracket 900 and the connecting part 220 can be connected by threads, snap-fit, bidirectional locking bearing, or welding.

[0206] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 , Figure 8 and Figure 9 As shown, the other of the heating plate 300 and the magnetic component 400 surrounds the connecting portion 220 and is spaced apart from the connecting portion 220; the other of the heating plate 300 and the magnetic component 400 is provided with a second mounting groove 1100, the opening of the second mounting groove 1100 facing the power unit 100; the connecting structure 500 includes a first bearing 530, the first bearing 530 is located in the second mounting groove 1100; the first bearing 530 is sleeved on the connecting portion 220, and the first bearing 530 connects the other of the heating plate 300 and the magnetic component 400.

[0207] In this embodiment, the other of the heating plate 300 and the magnetic component 400 is arranged around and spaced apart from the connecting portion 220. That is, the other of the heating plate 300 and the magnetic component 400 is sleeved on the connecting portion 220, and there is a gap between the other of the heating plate 300 and the magnetic component 400 and the connecting portion 220. In this way, when the connecting portion 220 rotates, the other of the heating plate 300 and the magnetic component 400 does not rotate with the connecting portion 220.

[0208] The connecting structure 500 includes a first bearing 530.

[0209] The first bearing 530 is located within the second mounting groove 1100. The first bearing 530 is sleeved on the connecting portion 220 and connects to the other of the heating plate 300 and the magnetic component 400. Thus, when the connecting portion 220 rotates, the other of the heating plate 300 and the magnetic component 400 will not rotate with the connecting portion 220. Simultaneously, the first bearing 530 also serves to connect the other of the heating plate 300 and the magnetic component 400 to the connecting portion 220.

[0210] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 , Figure 8 and Figure 9 As shown, the connection structure 500 also includes a seal 540, which is located in the second mounting groove 1100; the first bearing 530 and the groove wall of the second mounting groove 1100 are connected by the seal 540; or the seal 540 is connected between the connection part 220 and the groove wall of the second mounting groove 1100, and the seal 540 is located between the first bearing 530 and the bottom of the second mounting groove 1100.

[0211] In this embodiment, the connection structure 500 further includes a seal 540, which is located within the second mounting groove 1100.

[0212] The first bearing 530 and the groove wall of the second mounting groove 1100 are connected by a seal 540.

[0213] Alternatively, the seal 540 is connected between the connecting portion 220 and the groove wall of the second mounting groove 1100, and the seal 540 is located between the first bearing 530 and the bottom of the second mounting groove 1100.

[0214] The first bearing 530 and the seal 540 work together to connect the heating plate 300 and the magnetic component 400 to the connecting part 220. The seal 540 can also block water, dirt and other contaminants in the environment, thus ensuring the waterproof performance of the household appliance 1.

[0215] For example, the other of the heating plate 300 and the magnetic component 400 is provided with a second mounting groove 1100, the opening of the second mounting groove 1100 facing the third bracket 520.

[0216] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, the connection structure 500 also includes an oil seal 550 and / or a second limiting member 560.

[0217] The oil seal 550 is connected between the heating plate 300 and the other of the magnetic component 400 and the connecting part 220.

[0218] The second limiting member 560 is provided in the other of the heating plate 300 and the magnetic member 400.

[0219] The second limiting member 560 is used to limit the first bearing 530 along the length direction of the connecting part 220.

[0220] In this embodiment, the composition of the connection structure 500 is defined.

[0221] The connection structure 500 also includes an oil seal 550 and / or a second limiting element 560.

[0222] When the connection structure 500 also includes an oil seal 550, the oil seal 550 is connected between the other of the heating plate 300 and the magnetic component 400 and the connection part 220. The oil seal 550 can block water, dirt and other contaminants in the environment, and prevent water, dirt and other contaminants in the environment from entering the heating component 12.

[0223] When the connecting structure 500 also includes a second limiting member 560, the second limiting member 560 limits the first bearing 530 along the length direction of the connecting portion 220, so that the first bearing 530 cannot move along the length direction of the connecting portion 220, thereby limiting the other of the heating plate 300 and the magnetic member 400, and thus limiting the mating dimensions of the heating plate 300 and the magnetic member 400, providing structural support for the effective heating of the heating plate 300.

[0224] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, when the connecting structure 500 includes a second limiting member 560, the second limiting member 560 includes a washer 562 and a retaining ring 564.

[0225] Washer 562 is fitted onto the connecting part 220 and arranged at intervals from the connecting part 220.

[0226] The snap ring 564 is connected to the other of the heating plate 300 and the magnetic element 400.

[0227] Washer 562 abuts against the side of the first bearing 530 facing the power unit 100 and between the retaining ring 564.

[0228] In this embodiment, when the connecting structure 500 includes a second limiting member 560, the structure of the second limiting member 560 is defined.

[0229] The second limiting component 560 includes a washer 562 and a retaining ring 564.

[0230] Washer 562 is fitted onto connector 220 and spaced apart from connector 220. That is, washer 562 is arranged around connector 220, and there is a gap between washer 562 and connector 220.

[0231] The other of the heating plate 300 and the magnetic component 400 is connected to the retaining ring 564, and the washer 562 abuts against the side of the first bearing 530 facing the power unit 100 and between the retaining ring 564.

[0232] In other words, the snap ring 564 and the washer 562 cooperate to limit the first bearing 530 along the length direction of the connecting part 220, so that the first bearing 530 cannot move along the length direction of the connecting part 220, thereby limiting the other of the heating plate 300 and the magnetic component 400, and thus limiting the mating size of the heating plate 300 and the magnetic component 400, providing structural support for the effective heating of the heating plate 300.

[0233] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, the connecting structure 500 also includes a second bearing 510 and a third bracket 520.

[0234] The second bearing 510 is connected between the connecting part 220 and the third bracket 520.

[0235] The third support 520 is located between the heating plate 300 and the other of the magnetic components 400 and the power unit 100.

[0236] The other of the heating plate 300 and the magnetic component 400 is connected to the third bracket 520 and encloses the mounting cavity 1000.

[0237] One of the heating plate 300 and the magnetic component 400 is located within the mounting cavity 1000.

[0238] The other of the heating plate 300 and the magnetic component 400 is used for mounting and fixing the power unit 100, the connecting part 220 and the connecting structure 500.

[0239] In this embodiment, the other of the heating plate 300 and the magnetic component 400 is arranged around and spaced apart from the connecting portion 220. That is, the other of the heating plate 300 and the magnetic component 400 is sleeved on the connecting portion 220, and there is a gap between the other of the heating plate 300 and the magnetic component 400 and the connecting portion 220. In this way, when the connecting portion 220 rotates, the other of the heating plate 300 and the magnetic component 400 does not rotate with the connecting portion 220.

[0240] The connecting structure 500 also includes a second bearing 510 and a third bracket 520.

[0241] The second bearing 510 is connected between the connecting portion 220 and the third bracket 520. Specifically, the second bearing 510 is sleeved on the connecting portion 220, with its inner ring connected to the connecting portion 220 and its outer ring connected to the third bracket 520. The inner ring of the second bearing 510 can rotate relative to its outer ring. Thus, when the connecting portion 220 rotates, the third bracket 520 will not rotate with the connecting portion 220.

[0242] The third bracket 520 is located between the other of the heating plate 300 and the magnetic component 400 and the power unit 100. The other of the heating plate 300 and the magnetic component 400 is connected to the third bracket 520 and encloses the mounting cavity 1000. The mounting cavity 1000 has the function of accommodating one of the heating plate 300 and the magnetic component 400.

[0243] When the heating assembly 12 is installed, the other of the heating plate 300 and the magnetic component 400 is connected to the second body 16. That is, the other of the heating plate 300 and the magnetic component 400 is used for the installation and fixation of the power unit 100, the connecting part 220 and the connecting structure 500.

[0244] By defining the cooperation structure of the heating plate 300 and the other of the magnetic component 400, the second bearing 510, the third bracket 520 and the connecting part 220, dynamic balance can be ensured when the power unit 100 drives the connecting part 220 to rotate, reducing the amount of shaking. This helps to reduce the operating noise of the household appliance 1. At the same time, because this structure reduces the amount of shaking, it can ensure the cooperation position of the heating plate 300 and the magnetic component 400, which helps to improve the heating stability and reliability of the heating plate 300.

[0245] This embodiment provides a heating assembly 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: at least a portion of the heating plate 300 is located above the magnetic component 400.

[0246] In this embodiment, the mating structure of the heating plate 300 and the magnetic element 400 is defined.

[0247] At least a portion of the heating plate 300 is located above the magnetic element 400. That is, a portion of the heating plate 300 is located above the magnetic element 400, or the entire heating plate 300 is located above the magnetic element 400.

[0248] This arrangement keeps the heating plate 300 away from the first body 14 to avoid heating the first body 14 and affecting the operation of the electrical components inside the first body 14. While ensuring the heating effect of the heating component 12, it also ensures the operating temperature of other components of the household appliance 1, providing structural support for ensuring the performance of the household appliance 1.

[0249] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, the other of the heating plate 300 and the magnetic component 400 is provided with a second mounting groove 1100.

[0250] The opening of the second mounting slot 1100 faces the third bracket 520.

[0251] The connecting structure 500 also includes a first bearing 530 and a seal 540.

[0252] The first bearing 530 and the seal 540 are both located in the second mounting groove 1100.

[0253] The first bearing 530 is sleeved on the connecting part 220, and the seal 540 is connected between the first bearing 530 and the groove wall of the second mounting groove 1100.

[0254] In this embodiment, the mating structure of the heating plate 300, the magnetic element 400, and the connecting structure 500 is defined.

[0255] The other of the heating plate 300 and the magnetic component 400 is provided with a second mounting groove 1100. That is, the heating plate 300 is provided with a second mounting groove 1100, and the opening of the second mounting groove 1100 faces the third bracket 520, or the magnetic component 400 is provided with a second mounting groove 1100, and the opening of the second mounting groove 1100 faces the third bracket 520.

[0256] The connection structure 500 also includes a first bearing 530 and a seal 540, both of which are located in the second mounting groove 1100. The second mounting groove 1100 serves to accommodate the first bearing 530 and the seal 540.

[0257] A first bearing 530 is fitted onto the connecting portion 220, and a seal 540 is connected between the first bearing 530 and the groove wall of the second mounting groove 1100. The inner ring of the first bearing 530 is connected to the connecting portion 220, and the outer ring of the first bearing 530 is connected to the seal 540. The inner ring of the first bearing 530 can rotate relative to the outer ring of the first bearing 530. Thus, when the connecting portion 220 rotates, the other of the heating plate 300 and the magnetic component 400 will not rotate with the connecting portion 220.

[0258] The seal 540 is connected between the first bearing 530 and the groove wall of the second mounting groove 1100. The first bearing 530 and the seal 540 cooperate to connect the connecting part 220 and the other of the heating plate 300 and the magnetic component 400, which helps to reduce the amount of shaking, reduce the operating noise of the household appliance 1, and improve the heating stability and reliability of the heating plate 300. At the same time, the seal 540 also can block water, dirt and other contaminants in the environment, ensuring the waterproof performance of the household appliance 1.

[0259] For example, the seal 540 includes a sealing silicone pad or a sealing rubber pad.

[0260] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: the heating plate 300 includes any one or a combination of the following: an aluminum plate, an iron plate, or an aluminum-iron composite plate.

[0261] In this embodiment, the heating plate 300 includes any one or a combination of the following: an aluminum plate, an iron plate, or an aluminum-iron composite plate. The heating plate 300 has good thermal conductivity and can improve the heating effect on the second body 16.

[0262] This embodiment provides a heating assembly 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: the magnetic element 400 is ring-shaped; or there are multiple magnetic elements 400, and the multiple magnetic elements 400 are arranged circumferentially along the connecting portion 220.

[0263] In this embodiment, the magnetic component 400 is ring-shaped, so that the magnetic component 400 is arranged around the connecting portion 220 to facilitate the installation of the magnetic component 400. Furthermore, setting the magnetic component 400 as a ring can shorten the magnetic circuit, increase the magnetic flux density, and thus improve the starting torque.

[0264] Alternatively, there may be multiple magnetic components 400, which are distributed circumferentially along the connecting portion 220. This arrangement can reduce manufacturing costs.

[0265] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 7 As shown, when there are multiple magnetic elements 400, each magnetic element 400 includes multiple N poles and multiple S poles, and the number of pole pairs of the magnetic element 400 is greater than or equal to 4 pairs; and / or the heating assembly 12 also includes a first magnetic conductive element 1200, which is disposed between two adjacent magnetic elements 400.

[0266] In this embodiment, when there are multiple magnetic elements 400, the number of pole pairs of the magnetic elements 400 is greater than or equal to 4 pairs, which can improve the heating power.

[0267] The heating assembly 12 also includes a first magnetic conductor 1200, which is disposed between two adjacent magnetic conductors 400. This allows the magnetic flux density of the magnetic conductors 400 and the power unit 100 to be more concentrated, which is beneficial to improving rotation efficiency and heating efficiency.

[0268] For example, the first magnetic conductor 1200 is disposed between adjacent N poles and S poles.

[0269] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 , Figure 2 and Figure 3 As shown, the power unit 100 includes a rotor core 110 and a plurality of permanent magnets 120.

[0270] The rotor core 110 is provided with a connecting hole 112.

[0271] The connecting part 220 passes through the connecting hole 112.

[0272] Multiple permanent magnets 120 are disposed on the rotor core 110.

[0273] Multiple permanent magnets 120 are arranged circumferentially around the connecting hole 112.

[0274] In this embodiment, the structure of the power unit 100 is defined.

[0275] The power unit 100 includes a rotor core 110 and a plurality of permanent magnets 120. The rotor core 110 is provided with a connecting hole 112, and a connecting part 220 passes through the connecting hole 112 to meet the usage requirements of the power unit 100 driving the connecting part 220 to rotate.

[0276] Multiple permanent magnets 120 are disposed on the rotor core 110, and the multiple permanent magnets 120 are arranged circumferentially around the connecting hole 112.

[0277] The power unit 100 is used to cooperate with the stator 1300. Through the principle of axial magnetic flux coupling, the power unit 100 and the stator 1300 are separated. The stator 1300 rotates through the rotor drive connection 220.

[0278] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the heating assembly 12 also includes a stator 1300, which includes a stator core 1302, a winding 1304, and a winding support 1306.

[0279] Along the axial direction of the rotor core 110, the stator 1300 is arranged at intervals on the side of the power unit 100 away from the connecting structure 500.

[0280] The stator 1300 is used to drive the connecting part 220 to rotate via the power unit 100.

[0281] The winding 1304 is wound around the stator core 1302 via the winding bracket 1306.

[0282] In this embodiment, the structure of the heating component 12 is defined.

[0283] The heating assembly 12 also includes a stator 1300, which is arranged at intervals along the axial direction of the rotor core 110 on the side of the power unit 100 away from the connecting structure 500.

[0284] For example, the stator 1300 is disposed on the first body 14 of the household appliance 1, and the power unit 100 is disposed on the second body 16. The stator 1300 can drive the power unit 100 to rotate, so that the power unit 100 drives the connecting part 220 to rotate. Furthermore, the power unit 100 is located on one side of the stator 1300 along the axial direction. Through the principle of axial magnetic flux coupling, the power unit 100 and the stator 1300 are separated, so that the second body 16 and the first body 14 do not need to transmit power through a connecting shaft. At the same time, this arrangement can also reduce the thickness of the stator 1300 and the power unit 100 along the axial direction and the overall weight, thereby helping to reduce the overall height and weight of the household appliance 1, making it easier to store and transport the household appliance 1. When storing, the user can store the first body 14 with the stator 1300 and the second body 16 with the power unit 100 separately, improving the convenience of storage and carrying. The household appliance 1 proposed in this application can both process the medium inside the second body 16 and achieve the heating function through the rotation of the same connecting part 220, thereby improving the utilization rate of the connecting part 220. Moreover, it does not require electrical components to be installed on the second body 16, and can achieve whole-machine cleaning of the second body 16, thus improving the convenience of cleaning the second body 16.

[0285] Specifically, the stator 1300 includes a stator core 1302, a winding 1304, and a winding support 1306. The winding 1304 is wound around the stator core 1302 through the winding support 1306.

[0286] Among them, such as Figure 2 and Figure 3 As shown, the stator 1300 is fixed inside the first body 14 by a fixing bracket 1700.

[0287] In addition, by using the principle of axial magnetic flux coupling, the power unit 100 and the stator 1300 are set separately, eliminating the need for a connecting shaft to pass through the second body 16 to transmit power, thus improving the sealing performance of the second body 16. Furthermore, there is no need to set a coupling to connect the rotating shafts, thereby reducing the noise when the household appliance 1 is working.

[0288] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, the heating assembly 12 also includes a second magnetic conductor 1400 and a third magnetic conductor 1500.

[0289] The second magnetic conductor 1400 is located on the side of the magnetic conductor 400 facing the power unit 100.

[0290] The third magnetic conductor 1500 is located on the side of the permanent magnet 120 facing the magnetic component 400.

[0291] In this embodiment, the heating assembly 12 further includes a second magnetic conductor 1400 and a third magnetic conductor 1500.

[0292] The second magnetic guide 1400 is located on the side of the magnetic component 400 facing the power unit 100, and the third magnetic guide 1500 is located on the side of the permanent magnet 120 facing the magnetic component 400. By providing the second magnetic guide 1400 and the third magnetic guide 1500, the magnetic flux density of the magnetic component 400 and the power unit 100 can be more concentrated, thereby improving rotational efficiency and heating efficiency.

[0293] This embodiment provides a heating component 12. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 As shown, the heating assembly 12 also includes: a blade 210, with the blade 210 connected to the connecting part 220; or a stirring element, with the stirring element connected to the connecting part 220; or a fan blade, with the fan blade connected to the connecting part 220.

[0294] In this embodiment, the heating assembly 12 further includes a blade 210, a stirring element, or a fan blade. The blade 210 rotates to process the food. The stirring element rotates to stir the ingredients. The fan blade rotates to deliver airflow.

[0295] The blade 210, stirring component, and fan blade are collectively referred to as the processing unit. This application achieves both the processing of the medium within the second body 16 and the heating function through the rotation of the same connecting part 220, thus improving the utilization rate of the connecting part 220. In other words, one of the heating plate 300 and the magnetic component 400 shares the same power unit 100 and connecting part 220 with the processing unit, and the connecting part 220 serves as the mounting carrier for one of the heating plate 300 and the magnetic component 400. This eliminates the need for additional components to install and fix the heating plate 300 and the magnetic component 400, allowing the heating assembly 12 to not only have a heating function but also the function of processing the medium within the second body 16. This enriches the function of the heating assembly 12, reduces the number of components in the heating assembly 12, helps reduce product production costs, reduces the external dimensions of the heating assembly 12, and improves the performance and market competitiveness of the heating assembly 12.

[0296] Household appliance 1 includes any one of a food processor, a rice cooker, and a fan.

[0297] Specifically, in the case where the household appliance 1 includes a food processor, the first body 14 includes a base assembly 14a, and the second body 16 includes a cup assembly 16a. A blade 210 and a connecting portion 220 are connected. The cup assembly 16a is placed on the base assembly. Through the interaction between the stator 1300 and the power unit 100, the blade 210 rotates, thereby processing the food inside the cup assembly 16a. Simultaneously, the power unit 100 is fitted onto the connecting portion 220, driving the blade 210 to rotate. One of the magnetic component 400 and the heating plate 300 is fitted onto the connecting portion 220, enabling the connecting portion 220 to drive either the magnetic component 400 or the heating plate 300 to rotate. The power unit 100, the heating plate 300, and the magnetic component 400 are located on the same side of the blade 210.

[0298] Specifically, in the case where the household appliance 1 includes a rice cooker, the first body 14 includes a first pot body, the second body 16 includes a second pot body, a stirring member and a connecting part 220 are connected, the second pot body is disposed inside the first pot body, and the food inside the second pot body is heated by the heating plate 300. At least a part of the stirring member extends into the second pot body to stir the food inside the second pot body, thereby improving the uniformity of heating of the food inside the second pot body and preventing scorching. The power unit 100, the heating plate 300 and the magnetic member 400 are located on the same side of the stirring member.

[0299] Specifically, in the case where the household appliance 1 includes a fan, the fan head and fan base can be separated, facilitating the cleaning of the fan head. Simultaneously, when the fan head is installed in the fan base, the stator 1300 inside the fan base drives the power unit 100 inside the fan head to rotate. The power unit 100 then drives the fan blades to rotate via the connecting part 220, achieving the air delivery function. The power unit 100, heating plate 300, and magnetic component 400 are located on the same side of the fan blades.

[0300] like Figure 4 and Figure 5 As shown, a household appliance 1 according to some embodiments of this application includes: a heating component 12 as described in any of the above embodiments.

[0301] The household appliance 1 provided in this application includes a heating component 12 as described in any embodiment, and therefore has all the beneficial effects of the heating component 12, which will not be described in detail here.

[0302] This embodiment provides a household appliance 1. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 4 and Figure 5 As shown, the household appliance 1 also includes a first body 14 and a second body 16.

[0303] The stator 1300 of the heating assembly 12 is mounted on the first body 14 via a fixed bracket 1700.

[0304] The second body 16 can be installed on the first body 14.

[0305] The power unit 100, the connecting part 220, the heating plate 300, the magnetic component 400 and the connecting structure 500 are all located on the second body 16.

[0306] In this embodiment, the household appliance 1 also includes a first body 14 and a second body 16.

[0307] The stator 1300 of the heating assembly 12 is mounted on the first body 14 via a fixed bracket 1700. The power unit 100, connecting part 220, heating plate 300, magnetic component 400, and connecting structure 500 are all mounted on the second body 16. The stator 1300 can drive the power unit 100 to rotate, thereby causing the power unit 100 to drive the connecting part 220 to rotate. Furthermore, the power unit 100 is located on one side of the stator 1300 along the axial direction. Through the principle of axial magnetic flux coupling, the power unit 100 and the stator 1300 are coupled. The separation of the stator 1300 and the power unit 100 eliminates the need for a connecting shaft to transmit power. This arrangement also reduces the axial thickness of the stator 1300 and the power unit 100, as well as the overall weight, thereby reducing the overall height and weight of the household appliance 1. This facilitates the storage and transportation of the household appliance 1. When storing the appliance, the user can separately store the first body 14 with the stator 1300 and the second body 16 with the power unit 100, improving the convenience of storage and carrying.

[0308] In this configuration, one of the heating plate 300 and the magnetic component 400 is connected to the second body 16. Specifically, the other of the heating plate 300 and the magnetic component 400 is used for mounting and fixing the power unit 100, the connecting part 220, and the connecting structure 500. The power unit 100, the connecting part 220, and the connecting structure 500 are connected to the second body 16 via the other of the heating plate 300 and the magnetic component 400. This arrangement helps reduce the amount of shaking, ensures the proper alignment of the heating plate 300 and the magnetic component 400, reduces operating noise, and improves the stability and reliability of the heating plate 300.

[0309] The stator 1300 is located on the first body 14, and the power unit 100 is located on the second body 16. The power unit 100 is connected to the connecting part 220. Under the interaction of the magnetic fields of the stator 1300 and the power unit 100, the power unit 100 can rotate, thereby driving the connecting part 220 to rotate, thus processing the food inside the second body 16. The power unit 100 is located on one side of the stator 1300 along the axial direction. Through the principle of axial magnetic flux coupling, the power unit 100 and the stator 1300 are separated. At the same time, the axial thickness of the stator 1300 and the power unit 100, as well as their weight, can be reduced, which helps to reduce the overall height and weight of the household appliance 1, making it easier to store and transport the household appliance 1. In addition, by using the principle of axial magnetic flux coupling, the stator 1300 and the power unit 100 are set separately, eliminating the need for a connecting shaft to pass through the second body 16 to transmit power, thus improving the sealing performance of the second body 16. Furthermore, there is no need to set a coupling to connect the rotating shafts, thereby reducing the noise when the household appliance 1 is working.

[0310] This embodiment provides a household appliance 1. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: When the heating component 12 includes a blade 210, the household appliance 1 includes a food processor, the first body 14 includes a base assembly 14a, the second body 16 includes a cup assembly 16a, the cup assembly 16a can be installed on the base assembly 14a, and the blade 210 is located inside the cup assembly 16a; When the heating component 12 includes a stirring member, the household appliance 1 includes a rice cooker, the first body 14 includes a first pot body, the second body 16 includes a second pot body, the second pot body is disposed inside the first pot body, at least a portion of the stirring member extends into the second pot body, and the heating plate 300 is located at the bottom of the second pot body; When the heating component 12 includes fan blades, the household appliance 1 includes a fan, the first body 14 includes a fan base, the second body 16 includes a fan head, the fan head can be installed on the fan base, and the fan blades are disposed on the fan head and can rotate relative to the fan head.

[0311] In this embodiment, the household appliance 1 includes any one of a food processor, a rice cooker, and a fan.

[0312] Specifically, in the case where the household appliance 1 includes a food processor, the first body 14 includes a base assembly 14a, the second body 16 includes a cup assembly 16a, the blade 210 is connected to the connecting part 220, the cup assembly 16a is placed on the base assembly, and the blade 210 is rotated by the interaction between the stator 1300 and the power unit 100, thereby processing the food in the cup assembly 16a. At the same time, the power unit 100 is sleeved on the connecting part 220 to drive the blade 210 to rotate. One of the magnetic component 400 and the heating plate 300 is sleeved on the connecting part 220, so that the connecting part 220 can drive the magnetic component 400 or the heating plate 300 to rotate.

[0313] Specifically, when the household appliance 1 includes a rice cooker, the first body 14 includes a first pot body, the second body 16 includes a second pot body, the stirring member is connected to the connecting part 220, the second pot body is disposed in the first pot body, the heating plate 300 realizes the heating of the food in the second pot body, at least a part of the stirring member extends into the second pot body to realize the stirring of the food in the second pot body, thereby improving the uniformity of heating of the food in the second pot body, and also preventing the food from burning.

[0314] Specifically, when the household appliance 1 includes a fan, the fan head and the fan base can be separated, which facilitates cleaning of the fan head. At the same time, when the fan head is installed in the fan base, the stator 1300 in the fan base drives the power unit 100 in the fan head to rotate, and the power unit 100 drives the fan blades to rotate through the connecting part 220 to realize the air delivery function.

[0315] For example, by axially separating the stator 1300 and the power unit 100, and causing the stator 1300 to drive the power unit 100 to rotate the connecting part 220, the magnetic element 400 rotates with the connecting part 220 and generates eddy currents with the heating plate 300 (e.g., aluminum plate) so that the heating plate 300 heats up.

[0316] Based on the principle of axial magnetic flux coupling, the stator 1300 drives the power unit 100 to rotate. The power unit 100 drives the magnetic component 400 to rotate counterclockwise through the connecting part 220 and the one-way bearing 700. The magnetic component 400 generates eddy currents with the aluminum disc, causing the aluminum disc to heat up. When rotating clockwise, the magnetic component 400 does not rotate with the power unit 100, stirring but not heating, thus realizing the cold and hot beverage functions of the household appliance 1.

[0317] The heating power of the heating component 12 varies with the rotation speed of the connecting part 220. The higher the rotation speed of the connecting part 220, the greater the heating power of the heating component 12.

[0318] The heating power of the heating component 12 is infinitely adjustable, enabling constant temperature control. The heating of the cup body component 16a in this application is passive heating, which allows for water washing (e.g., dishwasher washing function), making it safe and reliable.

[0319] This application utilizes the principle of axial magnetic flux to rotate the power unit 100 and the magnetic component 400, thereby heating the heating plate 300. Eddy currents are generated by the changing rotating magnetic field cutting magnetic lines of force, thus heating the heating plate 300. This solution has a simple structure, achieves passive heating, has a wider range of applications, and addresses user pain points.

[0320] like Figure 2 As shown, the household appliance 1 also includes a first fastener 1800, and the mounting bracket 1700 is fixed by the first fastener 1800. The first fastener 1800 includes screws, bolts, rivets, etc., which will not be listed here.

[0321] like Figure 1 As shown, the heating assembly 12 also includes a second fastener 1600, through which the power unit 100 and the connecting part 220 are mounted and fixed. The second fastener 1600 includes screws, bolts, rivets, etc., which will not be listed here. For example, the household appliance 1 includes a water heater.

The terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium.
