Detailed Implementation

[0065] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0066] like Figures 1 to 4As shown, a heating structure according to a first aspect of the present disclosure includes: a housing for supporting a component to be supported; a heating assembly disposed within the housing for heating the component to be supported, wherein the heating assembly has a first heating part and a second heating part, the second heating part being arranged around the periphery of the first heating part, and a gap existing between the first heating part and the second heating part; and a floating assembly having a first floating part and a second floating part, the first floating part being connected to the first heating part, the second floating part being connected to the second heating part, and the floating assembly being used to make the first heating part and the second heating part float relative to each other; wherein the second floating part is located on the side of the second heating part away from the first heating part.

[0067] It is understood that the heating structure provided in this embodiment includes a shell, a heating component, and a floating component. The shell can be used to support the component to be supported. The heating component is disposed within the shell, and when the shell supports the component, the component can be heated by the heating component. Specifically, the heating component includes a first heating part and a second heating part, which heat the component to be supported. The floating component allows the first and second heating parts to float relative to each other. Specifically, the floating component may include a first floating part and a second floating part, wherein the first floating part is connected to the first heating part, and the second floating part is connected to the second heating part. The floating of the first and second floating parts allows both the first and second heating parts to float independently, enabling them to better conform to the bottom of the component to be supported, ensuring the heat transfer efficiency of the heating component and thus guaranteeing the heating efficiency and heating effect of the heating structure. Considering that the first and second heating parts expand and deform due to thermal expansion and contraction when they are in a heated state, a gap is provided between them to avoid mutual compression and interference during expansion, thereby improving reliability and the operational stability of the heating structure. Furthermore, the second floating part is located on the side of the second heating part away from the first heating part. This arrangement reduces the impact of the second floating part on the gap and improves the supporting performance of the second heating part on the load-bearing component, as well as the fit between the second heating part and the load-bearing component.

[0068] It should be noted that the floating component can have a certain degree of elasticity. When the part to be supported is pressed against the first heating part and the second heating part, the first floating part applies a rebound force to the first heating part, and the second floating part applies a rebound force to the second heating part, so as to ensure that the first heating part and the second heating part are always in close contact with the part to be supported, thereby ensuring the heat transfer efficiency and heat transfer effect of the heating component on the part to be supported.

[0069] In some examples, when the heating structure does not support the component to be supported, the top of the first heating part is higher than the top of the second heating part; or the top of the first heating part and the top of the second heating part are flush.

[0070] It is understandable that the floating stroke of the first heating element can be equal to that of the second heating element, so that the tops of the first and second heating elements remain flush when the heating structure is not carrying the component to be carried. This arrangement ensures support and improves stability when the heating structure carries the component. Alternatively, the floating stroke of the first heating element can be greater than that of the second heating element, and when the heating structure is not carrying the component, the top of the first heating element protrudes beyond the top of the second heating element. With this arrangement, when the heating structure carries the component, the component will apply pressure to the first heating element during its descent, causing it to pull the first heating element down until the tops of the first and second heating elements are flush. This allows the first and second heating elements to jointly support the component and heat it. This design allows for a greater rebound force between the first floating part and the first heating part, ensuring that the first heating part can better fit the bottom of the component to be supported, thereby improving the fit between the heating assembly as a whole and the component to be supported, thus ensuring the heat transfer efficiency of the heating assembly to the component to be supported, and improving the heating efficiency and heating effect of the heating structure.

[0071] In some examples, such as Figure 1 As shown, the second heating part is arranged around the periphery of the first heating part.

[0072] It is understood that the second heating element can be annular, surrounding the first heating element, and the first and second heating elements can float relative to each other under the action of the floating assembly. The first heating element is located at the center of the heating assembly, corresponding to the center of the bottom of the component to be supported. The second heating element corresponds to the outer side of the center of the bottom of the component to be supported. Under the action of the floating assembly, both the first and second heating elements can fit tightly against the bottom of the component to be supported, achieving uniform heating of the component, improving the contact effect between the component to be supported and the heating structure, and enhancing heating performance.

[0073] For example, the first heating part can be a first heating plate, the second heating part can be a second heating plate, and both the first heating plate and the second heating plate are annular. The second heating plate is arranged around the periphery of the second heating plate, and the centers of the first heating plate and the second heating plate coincide. The combination of the first heating plate and the second heating plate can form a complete annular structure.

[0074] In some examples, such as Figure 1As shown, the heating structure further includes a reflector plate disposed within the housing, and the heating component disposed on the reflector plate.

[0075] Understandably, the heating structure may include a reflector. Specifically, the reflector may be housed within the casing, forming a placement groove. The heating components are placed within this groove, with the tops of the first and second heating parts protruding beyond the opening of the groove. A portion of the heat emitted by the first and second heating parts directly acts on the component to be supported, while the remaining heat is reflected by the reflector to the bottom of the component, reducing heat loss, ensuring concentrated heat, and improving the heating efficiency and effect on the component.

[0076] For example, a connector may be provided inside the housing to connect the reflector to the housing. Specifically, the top end of the connector may be connected to the opening of the housing, and the bottom end may be connected to the upper edge of the groove formed by the reflector. On the vertical projection, the top end of the connector is a first circle, and the bottom end is a second circle, with the second circle falling inside the first circle. The center of the first circle coincides with the center of the second circle. The sidewall shape of the connector may be consistent with the shape of the outer sidewall of the component to be supported. This avoids interference with the component, limits the component, and prevents heat dissipation from the component, thus achieving concentrated heating of the component, ensuring uniform heating, and improving heating efficiency and effect.

[0077] In some examples, such as Figures 1 to 4 As shown, multiple first floating parts are provided, symmetrically arranged between the first heating part and the reflector with the central axis of the first heating part as the axis of symmetry; and / or multiple second floating parts are provided, symmetrically arranged between the second heating part and the reflector with the central axis of the second heating part as the axis of symmetry.

[0078] Understandably, multiple first floating parts can be provided to ensure the floating effect of the first heating part. Specifically, with the central axis of the first heating part as the axis of symmetry, multiple first floating parts are arranged symmetrically between the first heating part and the reflector. The reflector supports the first floating parts, which in turn cause the first heating part to float relative to the second heating part. The symmetrical arrangement of multiple first floating parts ensures a uniform distribution of the supporting force and floating force provided to the first heating part, ensuring force balance and providing sufficient floating force. This allows the first heating part to stably adhere to the bottom of the component to be supported, improving heat transfer and preventing tilting of the first heating part when the heating structure supports the component, thus improving stability.

[0079] For example, three first floating parts may be provided, with the included angle between each pair of adjacent first floating parts being 120°, so as to uniformly support the first heating part.

[0080] Understandably, multiple second floating parts can be provided to ensure the floating effect of the second heating part. Specifically, with the central axis of the second heating part as the axis of symmetry, multiple second floating parts are arranged symmetrically between the second heating part and the reflector. The reflector supports the second floating parts, which in turn cause the second heating part to float relative to the first heating part. The symmetrical arrangement of multiple second floating parts ensures a uniform distribution of the supporting and floating forces provided to the second heating part, ensuring force balance and providing sufficient floating force. This allows the second heating part to stably adhere to the bottom of the component to be supported, improving heat transfer and preventing tilting of the second heating part when the heating structure supports the component, thus improving stability.

[0081] For example, three second floating parts may be provided, with the included angle between each pair of adjacent second floating parts being 120°, so as to uniformly support the second heating part.

[0082] In some examples, such as Figures 1 to 3 As shown, the first floating part includes: a first rod, one end of which is connected to the first heating part, and the other end of which passes through the reflector; a first limiting member, which is disposed on the first rod and located between the first heating part and the reflector; a first elastic member, which is sleeved on the first rod and used to press against the first limiting member; and a second limiting member, which is disposed on the first rod and located on the side of the reflector away from the first heating part, and used to restrict the first rod from detaching from the reflector.

[0083] Understandably, the first floating part may include a first rod, a first limiting member, a first elastic member, and a second limiting member. One end of the first rod is connected to the bottom of the first heating part. The reflector may have a through hole, and the other end of the first rod passes through the through hole, located on the side of the reflector away from the first heating part. The first rod supports the first heating part. The first limiting member may be disposed on the first rod and located between the first heating part and the reflector; further, the first limiting member may be closer to the first heating part. The first elastic member may be sleeved on the first rod, with its top end located between the first heating part and the first rod. The bottom end of the first elastic member may be connected to the side of the reflector facing the first heating part, or may pass through the reflector on the side of the reflector away from the first heating part. The elastic force of the first elastic member causes the first heating part to float relative to the second heating part. The second limiting member is disposed on the first rod and located on the side of the reflector away from the first heating part. On the vertical projection, the area of ​​the second limiting member is larger than the area of ​​the through hole, so that the second limiting member restricts the separation of the first rod and the reflector. Specifically, after the component to be supported is removed from the heating structure, the rebound force of the elastic member is greater than the weight of the first heating part itself. The elastic member pushes the first limiting member, causing the first rod to move the first heating part upward. When it moves to the point where the second limiting member abuts against the reflector, the second limiting member restricts the first rod from moving further upward, preventing the first rod from coming out of the through hole and causing the first rod and the reflector to separate, thus improving reliability.

[0084] It should be noted that when the heating structure is not supporting the component to be supported, the top of the first heating element can be higher than the top of the second heating element. Correspondingly, the elastic force of the first elastic element is greater than the weight of the first heating element itself, but less than the sum of the weight of the first heating element and the weight of the component to be supported. With this configuration, when the heating structure is not supporting the component to be supported, the top of the first elastic element presses against the first limiting element, causing the first limiting element to push the first rod upwards, which in turn pushes the first heating element upwards, with the top of the first heating element protruding above the top of the second heating element. When the heating structure is supporting the component to be supported, the component first abuts against the top of the first heating element, applying pressure to the first heating element, causing the first elastic element to compress. The first heating element moves downwards until it is supported by both the first and second heating elements. Furthermore, the rebound force generated by the compression of the first elastic element pushes the first heating element tightly against the bottom of the component to be supported, ensuring the heat transfer efficiency and effect of the heating assembly on the component to be supported.

[0085] For example, the first elastic element may be a spring, which is sleeved on the first rod. The first limiting element may be a first cover, which passes through the first rod, and the first cover has a first groove formed on the side facing the reflector. The top of the spring may press against the bottom of the groove, and the side wall of the first groove may restrict the radial degree of freedom of the spring along the first rod, thereby improving stability.

[0086] For example, the first limiting member and the first rod can be a separate structure or an integrated structure, and the second limiting member and the first rod can be a separate structure or an integrated structure.

[0087] In some examples, such as Figures 1 to 4 As shown, the second floating part includes: a second rod, one end of which is connected to the second heating part, and the other end of which passes through the reflector; a third limiting member, which is disposed on the second rod and located between the second heating part and the reflector; a second elastic member, which is sleeved on the second rod and used to press against the second limiting member; and a fourth limiting member, which is disposed on the second rod and located on the side of the reflector away from the second heating part, and the fourth limiting member is used to restrict the first rod from detaching from the reflector.

[0088] Understandably, the first floating part may be provided with a second rod, a third limiting member, a second elastic member, and a fourth limiting member. One end of the second rod is connected to the bottom of the second heating part, and the reflector may have a through hole. The other end of the second rod passes through the through hole and is located on the side of the reflector away from the second heating part. The second rod supports the second heating part. The third limiting member may be provided on the second rod and located between the second heating part and the reflector; furthermore, the third limiting member may be closer to the second heating part. The second elastic member may be sleeved on the second rod, with its top end located between the second heating part and the second rod. The bottom end of the second elastic member may be connected to the side of the reflector facing the second heating part, or may pass through the reflector on the side of the reflector away from the second heating part. The elastic force of the second elastic member causes the second heating part to float relative to the second heating part. The fourth limiting member is provided on the second rod and is located on the side of the reflector away from the second heating part. Projected vertically, the area of ​​the fourth limiting member is larger than the area of ​​the through hole, thus preventing the separation of the second rod and the reflector. Specifically, after the component to be supported is removed from the heating structure, the rebound force of the elastic member is greater than the weight of the second heating part. The elastic member pushes the third limiting member, causing the second rod to move upward, thus moving the second heating part upward. When the second rod reaches the fourth limiting member against the reflector, the fourth limiting member prevents the second rod from moving further upward, avoiding the second rod from detaching from the through hole and causing separation between the second rod and the reflector, thereby improving reliability.

[0089] It should be noted that the elastic force of the second elastic element is greater than the weight of the second heating element itself, and the sum of the elastic forces of the first and second elastic elements is less than the sum of the weights of the first and second heating elements and the weight of the component to be supported. This ensures that the rebound forces of the first and second elastic elements allow the first and second heating elements to remain tightly fitted to the bottom of the component to be supported, thus guaranteeing the heat transfer efficiency and effect of the heating assembly on the component to be supported.

[0090] For example, the second elastic element can be a spring, which is sleeved on the second rod. The third limiting element can be a second cover, which passes through the second rod, and the second cover has a second groove formed on the side facing the reflector. The top of the spring can press against the bottom of the groove, and the side wall of the second groove can restrict the radial freedom of the spring along the second rod, thereby improving stability. Furthermore, while ensuring sufficient support capacity, the spring force should prevent the end of the second heating plate near the first heating plate from tilting downwards at a large angle, which would reduce the support capacity for the load-bearing component.

[0091] For example, the third limiting member and the second rod can be a separate structure or an integrated structure, and the fourth limiting member and the second rod can be a separate structure or an integrated structure.

[0092] In some examples, such as Figure 1 As shown, the first heating part includes: a first disc body connected to one end of the rod body; a first support frame connected to the first disc body for abutting against the reflector plate; and a first heating tube disposed on the first disc body; wherein, when the heating structure does not support the component to be supported, there is a gap between the first support frame and the reflector plate.

[0093] Understandably, the first heating element may include a first disc, a first support frame, and a first heating tube. The bottom of the first disc is connected to one end of a rod, allowing it to float relative to the second heating element via a floating component. The first support frame is mounted on the bottom of the first disc. When the heating structure is not supporting the component to be supported, the top of the first heating element may be higher than the top of the second heating element. Correspondingly, under the action of the first elastic member, the first disc moves upward until its top is higher than the top of the second heating element, while a gap remains between the bottom of the first support frame and the reflector. The first elastic member pushes against the first limiting member to keep the first rod supporting the first disc. When the heating structure is supporting the component to be supported, the component to be supported and the first disc descend, and the first support frame follows, descending until its bottom abuts against the reflector, thus supporting the first disc. Simultaneously, the first elastic member pushes against the first limiting member to ensure the first rod also supports the first disc, guaranteeing reliable support. The first heating tube can be embedded inside the first plate or set at the bottom of the first plate, and the bottom center of the component to be supported is heated by the first heating tube.

[0094] It is understandable that the first heating tube can be a ring structure, coiled at the first plate body, to ensure that the first heating tube heats the load-bearing component evenly, and to increase the heating area of ​​the first heating tube, thereby ensuring heating efficiency and heating effect.

[0095] In some examples, such as Figure 1 As shown, the first rod is closer to the end of the first plate that is closer to the second plate than the first heating tube.

[0096] Understandably, along the radial direction of the first disc, the first rod is closer to the end of the first disc near the second disc than the first heating tube; that is, the first rod is located outside the first heating tube. This arrangement ensures balanced force distribution when the first heating section supports the receiving component, which is beneficial for the stable floating of the first heating section.

[0097] In some examples, such as Figure 1 As shown, the second heating part includes: a second disc body, which is arranged around the periphery of the first disc body and connected to one end of the second rod body; a second support frame, which is connected to the second disc body and is used to abut against the reflector plate; and a second heating tube, which is disposed in the second disc body; wherein, when the heating structure does not support the component to be supported, there is a gap between the second support frame and the reflector plate.

[0098] Understandably, the second heating element may include a second disc, a second support frame, and a second heating tube. The second disc may be annular, surrounding the first disc, with a gap between them to ensure smooth floating of the first disc relative to the second disc by the floating element. One end of the second support frame is connected to a reflector, and the other end has a gap with the reflector. A second elastic element pushes against a third limiting element to keep the second rod supporting the first disc. When the heating structure carries the load-bearing component, the load-bearing component and the second disc descend, and the second support frame descends accordingly until its bottom end abuts against the reflector, supporting the second disc. Simultaneously, the second elastic element pushes against the third limiting element, ensuring the second rod also supports the second disc, guaranteeing reliable support. The second heating tube may be embedded inside the second disc or located at its bottom, heating the bottom center of the load-bearing component.

[0099] It is understandable that the second heating tube can be a ring structure, coiled at the second plate, to ensure uniform heating of the component to be supported, and to increase the heating area of ​​the second heating tube, thereby ensuring heating efficiency and heating effect.

[0100] In some examples, such as Figure 1 As shown, the second rod is closer to the end of the second disc that is farther away from the first disc than the second heating tube.

[0101] Understandably, along the radial direction of the second disc, the second rod is closer to the end of the second disc furthest from the first disc than the second heating tube; that is, the second rod is located outside the second heating tube. This arrangement ensures balanced force distribution when the second heating section supports the load-bearing component, which is beneficial for the stable floating of the second heating section.

[0102] In some examples, such as Figure 1 As shown, the gap is located between the first heating tube and the second heating tube.

[0103] It is understandable that, considering that the first and second heating tubes expand and deform due to thermal expansion and contraction when they are in a heating state, which in turn causes the first and second discs to expand and deform, especially the deformation between the first and second heating tubes, a gap is set between the first and second heating tubes to avoid the first heating part and the second heating part from expanding and squeezing each other, thereby improving reliability and the working stability of the heating structure.

[0104] In some examples, such as Figure 1 As shown, the distance between the center of the second rod and the center of the second heating tube is greater than the distance between the center of the first rod and the center of the first heating tube.

[0105] It is understandable that the distance between the center of the second rod and the center of the second heating tube along the radial direction of the second plate is greater than the distance between the center of the first rod and the center of the first heating tube. With this setting, the distance between the first heating tube and the second heating tube is closer when the positions of the first rod and the second rod remain unchanged. This ensures that the heating area of ​​the first heating tube and the second heating tube can be covered, reduces the impact of the interval between the first heating tube and the second heating tube on the heating effect, ensures heating uniformity, and improves the heating effect.

[0106] It should be noted that, while ensuring that the distance between the first heating tube and the second heating tube remains unchanged at the set distance, the distance between the center of the second rod and the center of the second heating tube is greater than the distance between the center of the first rod and the center of the first heating tube, so that the second rod is closer to the outer side of the second plate. Under the action of the second floating part, it is more conducive to the fit between the second plate and the component to be supported, thus ensuring the heating effect.

[0107] In some examples, such as Figure 1 As shown, the heating structure further includes a thermostat, which is retractably disposed at the top of the first plate; wherein, when the heating structure is not carrying the component to be carried, the thermostat protrudes from the top of the first plate and the top of the second plate.

[0108] Understandably, the heating structure can also be equipped with a temperature controller to detect the temperature of the component to be supported, thereby controlling the heating temperature and ensuring safe and reliable heating operations. Specifically, the temperature controller is located at the top of the first plate and can extend and retract vertically. When the heating structure is not supporting the component to be supported, the temperature controller can protrude from the top of both the first and second plates. This allows the temperature controller to first contact the bottom of the component when it is placed on the heating structure. The pressure from the component causes the temperature controller to drop, bringing the bottom of the component into contact with the first plate. The pressure exerted by the component on the first plate causes it to descend, so that both the first and second plates together abut against the bottom of the component. The thermostat can be electrically connected to the first heating unit and the second heating unit, and has a certain degree of resilience so that it can rebound under the gravity of the component to be supported, and always press against the bottom of the component to be supported, so as to accurately detect the current temperature of the component to be supported in real time. When the temperature of the component to be supported reaches the preset maximum temperature, the thermostat can control the first heating unit and the second heating unit to stop heating, so as to avoid the heating temperature from being too high and damaging the food, ensure heating safety, and improve reliability.

[0109] For example, the thermostat may include a housing, a temperature sensor, a controller, and a spring. The temperature sensor is housed within the housing, which protects it and improves reliability. The temperature sensor is attached to the inner top wall of the housing. The housing is made of a material with good thermal conductivity to ensure accurate temperature detection of the component being supported. The temperature sensor, the first heating element, and the second heating element are all electrically connected to the controller. The controller controls the operation of the first and second heating elements based on the temperature information of the component being supported detected by the temperature sensor. Specifically, if the temperature of the component being supported, as received by the controller from the temperature sensor, is greater than or equal to a preset maximum temperature, the controller stops heating the first and / or second heating elements. The spring may be connected to the bottom of the housing. The spring force is greater than the weight of the housing itself, ensuring that when the heating structure is not supporting a component, the spring lifts the housing, causing the thermostat to protrude from the top of the first plate. Meanwhile, the spring force is less than the sum of the weight of the outer shell and the weight of the component to be supported. When the heating structure supports the component to be supported, the spring is compressed, and the thermostat drops down so that the top of the thermostat is flush with the top of the first heating part. At the same time, the spring's rebound force makes the top of the thermostat press against the bottom of the component to be supported, ensuring accurate temperature control and improving reliability.

[0110] It should be noted that the temperature controller can be located in the middle of the first plate to ensure that it accurately detects the temperature of the center of the component to be supported, ensuring accurate temperature detection results, and ensuring that the rebound force applied by the temperature controller to the component to be supported is even, preventing tilting and improving reliability. For example, the first plate can be annular in shape, and the temperature controller can be cylindrical in shape, with the first plate and the temperature controller arranged concentrically.

[0111] In some examples, the extension stroke of the aforementioned thermostat is greater than the floating stroke of the aforementioned first heating element.

[0112] Understandably, the extension stroke of the thermostat needs to be greater than the floating stroke of the first heating element. This design ensures that when the heating structure is not supporting the component to be supported, the floating element drives the first heating element to rise, so that the top of the first heating element protrudes beyond the top of the second heating element. Simultaneously, the thermostat rises to protrude beyond the top of the first heating element. This ensures that when the component to be supported is installed on the heating structure, the bottom of the component will first contact the thermostat. Furthermore, even when the weight of the component causes both the first heating element and the thermostat to descend, the thermostat will always remain pressed against the bottom of the component due to its rebound, ensuring accurate temperature control and improving reliability.

[0113] In some examples, the first heating unit and the second heating unit described above can be controlled to heat individually or simultaneously.

[0114] It is understandable that the first heating unit and the second heating unit can be controlled to heat simultaneously to improve heating efficiency, or they can be controlled separately to form multiple heating modes and heating temperatures, which are suitable for various usage scenarios and improve user experience.

[0115] In some examples, a first support point is formed at the top of the second disc to support the component to be carried; and / or a second support point is formed on the reflector to support the component to be carried.

[0116] Understandably, a first support point can be formed at the top of the second plate to support the component to be supported when the heating structure is carrying it, ensuring the stability of the component and the heating effect of the second heating element. Simultaneously, a second support point can be formed on the reflector plate to support the component, further improving its stability. Furthermore, the second support point can be located on the side wall of the reflector plate or at a heat-resistant component fixed to the reflector plate.

[0117] In some examples, such as Figure 1 As shown, the housing has an opening for inserting the component to be supported, and the top surface profile of the heating part protrudes toward the opening.

[0118] Understandably, the top of the shell can be formed with an opening to create an open container, allowing the component to be placed inside through the opening and then received and heated by the first and second heating sections. Furthermore, considering that the heating sections deform during heating, with the deformation direction downwards, the overall profile of the first and second discs is designed as an arch, with the top profile of the arch protruding towards the opening. This strengthens the overall structural strength of the heating section, reduces deformation, increases the contact area between the heating section and the bottom of the component, and improves reliability.

[0119] It should be noted that the bottom of the component to be supported can also adopt an arched design, that is, the arched profile protrudes in the direction away from the heating part, so as to strengthen the overall structural strength of the component to be supported, reduce the amount of deformation, increase the contact area between the bottom of the component to be supported and the heating part, and improve reliability.

[0120] According to a second aspect of the present disclosure, a cooking appliance is provided, comprising: a heating structure as described in any of the above technical solutions; and a pot body for cooperating with the heating structure.

[0121] It is understood that cooking appliances can be equipped with the aforementioned heating structure, thus possessing all the beneficial effects of such a structure, which will not be elaborated upon here. The pot body can serve as a support component, used in conjunction with the heating structure. Specifically, when the pot body is placed on the heating structure, the bottom of the pot body will first contact the thermostat, pressing it downwards until the bottom of the pot body contacts the first plate and presses it downwards until the pot body is supported by both the first and second plates. The thermostat, under the action of its rebound force, adheres tightly to the bottom of the pot body to accurately detect its temperature. The first and second heating parts can heat the pot body simultaneously or individually, and the first heating part, under the action of the floating part, adheres tightly to the pot body, improving the contact between the pot body and the first heating part, ensuring the heat transfer efficiency of the heating assembly to the support component, and improving the heating efficiency and heating effect of the heating structure.

[0122] For example, the bottom of the pot body can adopt an arched design, that is, the arched profile protrudes in the direction away from the heating part, so as to strengthen the overall structural strength of the component to be supported and reduce the amount of deformation. Correspondingly, the overall profile design of the first heating part and the second heating part is also arched, and the top profile of the arch protrudes in the direction of the opening of the shell, so as to strengthen the overall structural strength of the heating part and reduce the amount of deformation. When used together, the contact area between the heating part and the bottom of the component to be supported can be increased, thereby improving the heating efficiency.
