[0052] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0053] As Figures 1 to 3As shown, according to the first aspect of the embodiments of the present disclosure, a heating structure 100 is provided, which comprises a housing 110 configured to carry a to-be-carried object, and a heating assembly 120 arranged in the housing 110 and configured to heat the to-be-carried object, wherein the heating assembly 120 is provided with a first heating part 121 and a second heating part 122, the first heating part 121 is movable relative to the second heating part 122, and a floating part 130 is connected to the first heating part 121 and configured to make the first heating part 121 float relative to the second heating part 122. In the case that the heating structure 100 does not carry the to-be-carried object, the top end of the first heating part 121 is higher than the top end of the second heating part 122. In the case that the heating structure 100 carries the to-be-carried object, the to-be-carried object abuts against the top end of the first heating part 121 and the top end of the second heating part 122.

[0054] It can be understood that the heating structure 100 provided by the embodiments of the present disclosure is provided with the housing 110, the heating assembly 120 and the floating part 130. The housing 110 can be used to carry the to-be-carried object. The heating assembly 120 is arranged in the housing 110, and in the case that the housing 110 carries the to-be-carried object, the heating assembly 120 can heat the to-be-carried object. Specifically, the heating assembly 120 is provided with the first heating part 121 and the second heating part 122, and the floating part 130 is connected to the first heating part 121 and can drive the first heating part 121 to float relative to the second heating part 122. Further, in the case that the heating structure 100 does not carry the to-be-carried object, the floating part 130 can drive the first heating part 121 to float, so that the top end of the first heating part 121 protrudes from the top end of the second heating part 122. In the case that the heating structure 100 carries the to-be-carried object, the to-be-carried object exerts pressure on the first heating part 121, so that the to-be-carried object drives the first heating part 121 to descend, and the to-be-carried object is supported by the first heating part 121 and the second heating part 122, and the to-be-carried object is heated by the first heating part 121 and / or the second heating part 122. By arranging the floating part 130, the first heating part 121 can better fit the bottom of the to-be-carried object, improve the fitting degree of the heating assembly 120 as a whole and the to-be-carried object, thereby ensuring the heat transfer efficiency of the heating assembly 120 to the to-be-carried object, and improving the heating efficiency and heating effect of the heating structure 100.

[0055] It should be noted that the floating part 130 can have a certain elasticity, and when the to-be-carried part is placed in the shell 110, it will first abut against the first heating part 121 protruding from the second heating part 122 and apply pressure to the first heating part 121, so that the first heating part 121 moves downward until the top end of the first heating part 121 and the top end of the second heating part 122 jointly support the to-be-carried part. The floating part 130 applies an upward pushing force to the first heating part 121 to ensure that the first heating part 121 is always closely attached to the to-be-carried part, thereby ensuring the heat transfer efficiency and effect of the heating assembly 120 on the to-be-carried part.

[0056] Exemplarily, the to-be-carried part can be a pot body. When the first heating part 121 and the second heating part 122 jointly support the pot body, the top end of the first heating part 121 and the top end of the second heating part 122 are in the same profile and are attached to the bottom profile of the pot body. For example, the bottom profile of the pot body and the top end profile of the heating assembly 120 are mutually matching circular arcs.

[0057] In some examples, as shown in Figure 1 The second heating part 122 is annularly arranged on the periphery of the first heating part 121.

[0058] It can be understood that the second heating part 122 can be annularly arranged on the periphery of the first heating part 121, and the first heating part 121 is floating relative to the second heating part 122 through the floating part 130. The first heating part 121 is located at the overall middle position of the heating assembly 120, so that the first heating part 121 corresponds to the middle position of the bottom of the to-be-carried part. When the heating structure 100 carries the to-be-carried part, the second heating part 122 is in hard contact with the to-be-carried part to ensure the supporting effect of the second heating part 122 on the to-be-carried part, and the corresponding position of the bottom of the to-be-carried part is heated through the second heating part 122. The first heating part 121 can be closely attached to the middle position of the bottom of the to-be-carried part under the action of the floating part 130, so as to supplement the heating heat of the middle part of the to-be-carried part, realize uniform heating, improve the contact effect of the to-be-carried part and the heating structure 100, and improve the heating performance.

[0059] Exemplarily, the first heating part 121 can be a first heating disc, and the second heating part 122 can be a second heating disc. Both the first heating disc and the second heating disc are circular rings, the second heating disc is annularly arranged on the periphery of the second heating disc, and the centers of the first heating disc and the second heating disc coincide. The combination of the first heating disc and the second heating disc can form a complete circular ring structure.

[0060] In some examples, as shown in Figure 1 The heating structure 100 further comprises a reflection plate 140 arranged in the shell 110, and the heating assembly 120 is arranged on the reflection plate 140.

[0061] It can be understood that the heating structure 100 can be provided with a reflecting plate 140, specifically, the reflecting plate 140 can be arranged in the shell 110, and the reflecting plate 140 can surround to form a placing groove, the heating assembly 120 is arranged in the placing groove, and the top end of the first heating part 121 and the top end of the second heating part 122 protrude from the slot of the placing groove. Part of the heat emitted by the first heating part 121 and the second heating part 122 directly acts on the to-be-carried member, and the remaining heat is reflected to the bottom of the to-be-carried member through the reflecting plate 140, reducing heat loss, ensuring heat concentration, improving heating efficiency and heating effect on the to-be-carried member.

[0062] Exemplarily, the inside of the shell 110 can be provided with a connecting piece, and the reflecting plate 140 is connected to the shell 110 through the connecting piece. Specifically, the top end of the connecting piece can be connected to the opening of the shell 110, and the bottom end is connected to the upper edge of the slot of the placing groove surrounded by the reflecting plate 140, and the projection of the connecting piece in the vertical direction is projected as a first circle, the projection of the bottom end of the connecting piece is projected as a second circle, and the second circle falls into the first circle, the center of the first circle and the center of the second circle coincide, and the side wall profile shape of the connecting piece can be consistent with the shape of the outer side wall profile of the to-be-carried member. On the one hand, it can avoid interference with the to-be-carried member, on the other hand, it can limit the to-be-carried member, and on the other hand, it can block the heat emission of the to-be-carried member, realize concentrated heating of the to-be-carried member, ensure uniform heating, and improve heating efficiency and heating effect.

[0063] In some examples, as shown in Figures 1 to 3 The above floating part 130 is provided with a plurality of symmetrically arranged between the above first heating part 121 and the above reflecting plate 140.

[0064] It can be understood that the floating part 130 can be provided with a plurality of floating parts to ensure the floating effect of the first heating part 121. Specifically, the center axis of the first heating part 121 is taken as the symmetry axis, and the plurality of floating parts 130 are arranged in an axisymmetric manner between the first heating part 121 and the reflecting plate 140. The floating part 130 is supported by the reflecting plate 140, and the floating part 130 drives the first heating part 121 to float relative to the second heating part 122. The axisymmetric arrangement of the plurality of floating parts 130 can ensure that the supporting force and the floating force provided to the first heating part 121 are uniformly distributed, the first heating part 121 is balanced, and sufficient floating force can be provided, so that the first heating part 121 can stably adhere to the bottom of the to-be-carried member, improve the heat transfer effect, avoid the first heating part 121 from being inclined when the heating structure 100 carries the to-be-carried member, and improve the stability.

[0065] Exemplarily, the floating part 130 can be provided with three, and the included angle between each adjacent two floating parts 130 is 120°, so as to uniformly support the first heating part 121.

[0066] In some examples, as shown in the drawings, the floating part 130 comprises a rod body 131, one end of the rod body 131 is connected to the first heating part 121, and the other end is connected to the reflecting plate 140; a first limiting part 132 is arranged on the rod body 131 and located between the first heating part 121 and the reflecting plate 140; and an elastic part 133 is sleeved on the rod body 131 and used for pressing on the first limiting part 132. Figures 1 to 3

[0067] It can be understood that the floating part 130 can be provided with the rod body 131, the first limiting part 132 and the elastic part 133. Among them, one end of the rod body 131 is connected to the bottom of the first heating part 121, and the other end of the rod body 131 is connected to the side of the reflecting plate 140 facing the first heating part 121, and the first heating part 121 is supported by the rod body 131. The first limiting part 132 can be arranged on the rod body 131 and located between the first heating part 121 and the reflecting plate 140, and further, the first limiting part 132 can be closer to the first heating part 121. The elastic part 133 can be sleeved on the rod body 131, and the elastic part 133 is sleeved on the rod body 131, the top end of the elastic part 133 is located between the first heating part 121 and the rod body 131, and the bottom end of the elastic part 133 can be connected to the side of the reflecting plate 140 facing the first heating part 121, or can be sleeved on the reflecting plate 140 located on the side of the reflecting plate 140 away from the first heating part 121. The first heating part 121 is floated relative to the second heating part 122 by the elastic force of the elastic part 133.

[0068] It should be noted that the elastic force of the elastic part 133 is greater than the self-gravity of the first heating part 121, and less than the sum of the self-gravity of the first heating part 121 and the self-gravity of the to-be-supported part. In this way, in the case that the heating structure 100 does not support the to-be-supported part, the top end of the elastic part 133 presses on the first limiting part 132, so that the first limiting part 132 pushes the rod body 131 to rise, and in turn pushes the first heating part 121 to rise, and the top end of the first heating part 121 protrudes from the top end of the second heating part 122. In the case that the heating structure 100 supports the to-be-supported part, the to-be-supported part first abuts against the top end of the first heating part 121 and exerts a pressure on the first heating part 121, so that the elastic part 133 is compressed, and the first heating part 121 moves downward until the to-be-supported part is supported by the first heating part 121 and the second heating part 122 together. And the elastic force generated by the compression of the elastic part 133 pushes the first heating part 121 to tightly adhere to the bottom of the to-be-supported part, so as to ensure the heat transfer efficiency and effect of the heating assembly 120 on the to-be-supported part.

[0069] ​Exemplarily, the elastic member 133 can be a spring, and the spring is sleeved on the rod body 131. The first limiting member 132 can be a cover body, which is penetrated through the rod body 131, and a groove is formed on the side of the cover body facing the reflecting plate 140. The top end of the spring can abut against the groove bottom, and the side wall of the groove can limit the radial freedom of the spring along the rod body 131, thereby improving the stability.

[0070] In some examples, as shown in Figure 1 The floating part 130 further includes a second limiting member 134. The other end of the rod body 131 is penetrated through the reflecting plate 140. The second limiting member 134 is arranged on the rod body 131 and located on the side of the reflecting plate 140 away from the first heating part 121. The second limiting member 134 is used to limit the rod body 131 from separating from the reflecting plate 140.

[0071] It can be understood that the floating part 130 can further be provided with the second limiting member 134. Specifically, the reflecting plate 140 can be provided with a through hole, and the other end of the rod body 131 penetrates through the through hole. The second limiting member 134 is arranged on the rod body 131 and located on the side of the reflecting plate 140 away from the first heating part 121. In the vertical projection, the area of the second limiting member 134 is greater than the area of the through hole, so that the second limiting member 134 limits the rod body 131 and the reflecting plate 140 from separating. Specifically, after the to-be-carried member is taken away from the heating structure 100, the elastic force of the elastic member 133 is greater than the self-gravity of the first heating part 121. The elastic member 133 pushes the first limiting member 132, so that the rod body 131 drives the first heating part 121 to move upward. When the second limiting member 134 abuts against the reflecting plate 140, the second limiting member 134 limits the rod body 131 from continuing to move upward, thereby avoiding the rod body 131 from separating from the reflecting plate 140 due to the rod body 131 being taken out from the through hole, and improving the reliability.

[0072] Exemplarily, the first limiting member 132 and the rod body 131 can be a split structure or an integral structure, and the second limiting member 134 and the rod body 131 can be a split structure or an integral structure.

[0073] In some examples, as shown in Figure 1 The first heating part 121 includes a first disc body 1211 connected to one end of the rod body 131, a first support frame 1212 connected to the first disc body 1211 and used to abut against the reflecting plate 140, and a first heating pipe 1213 arranged on the first disc body 1211. In the case that the heating structure 100 does not carry the to-be-carried member, there is a gap between the first support frame 1212 and the reflecting plate 140.

[0074] It can be understood that the first heating part 121 can be provided with a first disc body 1211, a first support frame 1212 and a first heating pipe 1213. The bottom of the first disc body 1211 is connected to one end of the rod body 131, so as to drive the first disc body 1211 to float relative to the second heating part 122 through the floating part 130. The first support frame 1212 is arranged on the bottom of the first disc body 1211, and when the heating structure 100 does not carry the to-be-carried part, the elastic force of the elastic member 133 is greater than the overall gravity of the first heating part 121, and under the action of the elastic member 133, the first disc body 1211 moves upward, so that the top end of the first disc body 1211 is higher than the top end of the second heating part 122, and at the same time, a gap is left between the bottom end of the first support frame 1212 and the reflecting plate 140. The elastic member 133 pushes the first limiting member 132, so that the rod body 131 supports the first disc body 1211. When the heating structure 100 carries the to-be-carried part, the sum of the to-be-carried part and the gravity of the first heating part 121 is greater than the elastic force of the elastic member 133, the to-be-carried part and the first disc body 1211 descend, the first support frame 1212 descends along with the to-be-carried part and the first disc body 1211, until the bottom end of the first support frame 1212 abuts against the reflecting plate 140, and the first disc body 1211 is supported by the first support frame 1212. At the same time, the elastic member 133 pushes the first limiting member 132, so that the rod body 131 supports the first disc body 1211 together, to ensure the support reliability. The first heating pipe 1213 can be embedded in the inside of the first disc body 1211 or arranged at the bottom of the first disc body 1211, and the middle position of the bottom of the to-be-carried part is heated by the first heating pipe 1213.

[0075] It can be understood that the first heating pipe 1213 can be in a ring structure, and arranged at the first disc body 1211, to ensure that the first heating pipe 1213 uniformly heats the to-be-carried part, and to increase the heating area of the first heating pipe 1213, to ensure the heating efficiency and the heating effect.

[0076] In some examples, as shown in Figure 1 The second heating part 122 includes a second disc body 1221 arranged around the first disc body 1211, a second support frame 1222 connected to the reflecting plate 140 and the second disc body 1221 respectively, and a second heating pipe 1223 arranged in the second disc body 1221.

[0077] It can be understood that the second heating part 122 can be provided with a second disc body 1221, a second support frame 1222 and a second heating pipe 1223. The second disc body 1221 can be annular and arranged around the periphery of the first disc body 1211. A gap can exist between the second disc body 1221 and the first disc body 1211 to ensure that the floating part 130 can smoothly drive the first disc body 1211 to float relative to the second disc body 1221. One end of the second support frame 1222 is connected to the reflecting plate 140, and the other end is connected to the second disc body 1221, so as to fix the second disc body 1221 to the reflecting plate 140 through the second support frame 1222. The second heating pipe 1223 can be embedded in the inside of the second disc body 1221 or arranged at the bottom of the second disc body 1221, and the corresponding position of the bottom of the to-be-carried part is heated through the second heating pipe 1223.

[0078] It can be understood that the second heating pipe 1223 can be annular, and arranged at the second disc body 1221 to ensure that the second heating pipe 1223 uniformly heats the to-be-carried part and increases the heating area of the second heating pipe 1223 to ensure the heating efficiency and effect.

[0079] In some examples, as shown in Figure 1 The heating structure 100 further includes a temperature controller 150 telescopically arranged at the top end of the first disc body 1211. When the heating structure 100 does not carry the to-be-carried part, the temperature controller 150 protrudes from the top end of the first disc body 1211.

[0080] It can be understood that the heating structure 100 can also be provided with a temperature controller 150, which can detect the temperature of the to-be-carried object to control the heating temperature and ensure the safety and reliability of the heating operation. Specifically, the temperature controller 150 is arranged at the top end of the first disc body 1211 and can be extended and retracted in the vertical direction. In the case that the heating structure 100 does not carry the to-be-carried object, the temperature controller 150 can protrude from the top end of the first disc body 1211. In this way, when the to-be-carried object is placed on the heating structure 100, the bottom of the to-be-carried object first contacts the temperature controller 150, and the temperature controller 150 is lowered under the pressure of the to-be-carried object, so that the bottom of the to-be-carried object contacts the first disc body 1211. The pressure exerted by the to-be-carried object on the first disc body 1211 can cause the first disc body 1211 to lower, so that the first disc body 1211 and the second disc body 1221 abut against the bottom of the to-be-carried object. The temperature controller 150 can be electrically connected to the first heating part 121 and the second heating part 122 and has a certain resilience, so as to rebound under the action of the gravity of the to-be-carried object and always press against the bottom of the to-be-carried object, so as to accurately and timely detect the current temperature of the to-be-carried object. In the case that the temperature of the to-be-carried object reaches the preset maximum temperature, the first heating part 121 and the second heating part 122 can be controlled to stop heating by the temperature controller 150, so as to avoid damage to the food caused by excessively high heating temperature and ensure the heating safety and improve the reliability.

[0081] Exemplarily, the temperature controller 150 can be provided with a shell, a temperature sensor, a controller and a spring. The temperature sensor is arranged in the shell to protect the temperature sensor and improve the reliability, and the temperature sensor is attached to the inner wall at the top end of the shell. The shell is made of a material with good heat transfer performance, so as to ensure that the temperature sensor can accurately detect the temperature of the to-be-carried object. The temperature sensor, the first heating pipe 1213 and the second heating pipe 1223 are electrically connected to the controller, and the controller can control the working conditions of the first heating pipe 1213 and the second heating pipe 1223 according to the temperature information of the to-be-carried object detected by the temperature sensor. Specifically, in the case that the temperature information of the to-be-carried object sent by the temperature sensor is greater than or equal to the preset maximum temperature, the controller controls the first heating pipe 1213 and / or the second heating pipe 1223 to stop heating. The spring can be connected to the bottom of the shell, and the elastic force of the spring is greater than the self-gravity of the shell, so as to ensure that the spring lifts the shell in the case that the heating structure 100 does not carry the to-be-carried object, so that the temperature controller 150 protrudes from the top end of the first disc body 1211. At the same time, the elastic force of the spring is less than the sum of the self-gravity of the shell and the self-gravity of the to-be-carried object, so that the spring is compressed in the case that the heating structure 100 carries the to-be-carried object, and the temperature controller 150 is lowered, so that the top of the temperature controller 150 is flush with the top of the first heating part 121. At the same time, the rebound force of the spring causes the top end of the temperature controller 150 to tightly contact the bottom of the to-be-carried object, so as to ensure that the temperature control effect of the temperature controller 150 is accurate and improve the reliability.

[0082] It should be noted that the temperature controller 150 can be located in the middle of the first disc body 1211 to ensure that the temperature controller 150 accurately detects the temperature of the middle of the to-be-carried member, ensures that the detection temperature result is accurate, and ensures that the rebound force exerted by the temperature controller 150 on the to-be-carried member is balanced, thereby avoiding tilting and improving reliability. Exemplarily, the whole of the first disc body 1211 can be annular, and the whole of the temperature controller 150 can be cylindrical, and the first disc body 1211 and the temperature controller 150 are concentrically arranged.

[0083] In some examples, the telescopic stroke of the temperature controller 150 is greater than the floating stroke of the first heating part 121.

[0084] It can be understood that the telescopic stroke of the temperature controller 150 needs to be greater than the floating stroke of the first heating part 121. In this way, it can be ensured that when the heating structure 100 is not carrying the to-be-carried member, the floating part 130 drives the first heating part 121 to rise, so that the top end of the first heating part 121 protrudes from the top end of the second heating part 122, and at the same time, the temperature controller 150 rises to protrude from the top end of the first heating part 121. When the to-be-carried member is installed on the heating structure 100, the bottom of the to-be-carried member will first contact the temperature controller 150, and in the case that the first heating part 121 and the temperature controller 150 are both lowered due to the self-gravity of the to-be-carried member, the temperature controller 150 always presses the bottom of the to-be-carried member due to the rebound, thereby ensuring that the temperature control effect of the temperature controller 150 is accurate and improving the reliability.

[0085] In some examples, the first heating part 121 and the second heating part 122 can be controlled to heat separately or simultaneously.

[0086] It can be understood that the first heating part 121 and the second heating part 122 can be controlled to heat simultaneously to improve the heating efficiency, or can be controlled to heat separately to form multiple heating modes and heating temperatures, which are suitable for various use scenarios and improve user experience.

[0087] In some examples, the top end of the second disc body 1221 forms a first supporting point for supporting the to-be-carried member, and / or the reflecting plate 140 forms a second supporting point for supporting the to-be-carried member.

[0088] Understandably, a first support point can be formed at the top of the second plate 1221 to support the component to be supported when the heating structure 100 is carrying it, ensuring the stability of the component and the heating effect of the second heating part 122 on the component. Simultaneously, a second support point can be formed on the reflector 140 to support the component, further improving its stability. Furthermore, the second support point can be located on the side wall of the reflector 140 or at a heat-resistant part fixed to the reflector 140.

[0089] In some examples, such as Figure 1 As shown, the housing 110 has an opening for inserting the component to be supported, and the top surface profile of the heating part protrudes toward the opening.

[0090] Understandably, the top of the housing 110 may have an opening, making the housing 110 an open container. The component to be supported can be placed inside the housing 110 through the opening, and then received and heated by the first heating element 121 and the second heating element 122. Furthermore, considering that the heating elements will deform during heating, and that the deformation direction is downward, the overall surface of the first disc 1211 and the second disc 1221 is designed to be arched, with the top profile of the arch protruding towards the opening. This strengthens the overall structural strength of the heating elements, reduces deformation, increases the contact area between the heating elements and the bottom of the component to be supported, and improves reliability.

[0091] 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.

[0092] According to a second aspect of the present disclosure, a cooking appliance is provided, comprising: a heating structure 100 as described in any of the above technical solutions; and a pot body for cooperating with the heating structure 100.

[0093] It can be understood that the cooking utensil can be provided with the heating structure 100 described above, thus having all the beneficial effects of the heating structure 100, which will not be repeated here. The pot body can be used as a to-be-carried member and cooperates with the heating structure 100. Specifically, when the pot body is placed on the heating structure 100, the bottom of the pot body will first contact the temperature controller 150, and continue to move downward by pressing the temperature controller 150, the bottom of the pot body will contact the first disc body 1211 and press the first disc body 1211 to move downward, until the pot body is supported by the first disc body 1211 and the second disc body 1221. The temperature controller 150 is tightly attached to the bottom of the pot body under the action of the elastic force, so as to accurately detect the temperature of the pot body. The first heating part 121 and the second heating part 122 can heat the pot body simultaneously or individually, and the first heating part 121 is tightly attached to the pot body under the action of the floating part 130, which improves the contact condition of the pot body and the first heating part 121, ensures the heat transfer efficiency of the heating assembly 120 to the to-be-carried member, and improves the heating efficiency and heating effect of the heating structure 100.

[0094] Exemplarily, the bottom of the pot body can adopt an arch-shaped design, that is, the top surface profile of the arch shape protrudes in the direction away from the heating part, so as to strengthen the overall structural strength of the to-be-carried member and reduce the deformation amount. Correspondingly, the overall surface profile of the first heating part 121 and the second heating part 122 is also arch-shaped, and the top surface profile of the arch shape protrudes in the direction of the opening of the shell 110, so as to strengthen the overall structural strength of the heating part and reduce the deformation amount. The cooperation can increase the contact area of the heating part and the bottom of the to-be-carried member and improve the heating efficiency.
