Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to a cooking appliance. BACKGROUND

[0002] In the existing cooking appliance, such as electric stew pot, it includes heating base, pot body and inner container, the inner container is located in the pot body and placed on the heating base, and then the food materials in the inner container are heated. The material of the inner container is usually ceramic. Although ceramic can keep the original flavor of food materials, due to the low thermal conductivity of ceramic material, the heat generated by the heating device of the heating base cannot effectively heat the food materials in the inner container, and most of the heat is diffused to the surrounding through the bottom of the heating device, resulting in waste of most of the heat, low heating efficiency of the heating device and long cooking time.

[0003] Although the existing cooking appliance has a side heating / heat conducting structure attached to the side wall of the ceramic pot, because the material of the pot body is ceramic and the size tolerance is large, when the side heating / heat conducting structure heats or insulates the side of the ceramic pot, a certain gap is required to be reserved between the side structure and the side of the ceramic pot during design to take into account that various deformation amounts of the ceramic pot cannot effectively contact the side of the ceramic pot, and the heat can only heat the ceramic pot through radiation, the side heating efficiency is low, and the cooking time is long. SUMMARY

[0004] Therefore, it is necessary to provide a cooking appliance to ensure that the heat conducting member effectively contacts the side wall of the inner container.

[0005] The present application provides a cooking appliance, which comprises a heating base including a shell and a heating disc arranged in the shell; an inner container capable of being arranged in the shell and placed on the upper surface of the heating disc; and at least one heat conducting assembly, each of the heat conducting assemblies comprising a heat conducting member, a connecting member and a force applying member, the heat conducting member being rotatably arranged at the edge of the heating disc through the connecting member and having a rotation axis, and the force applying member abutting against the heat conducting member for applying force to drive the heat conducting member to rotate around the rotation axis to fit the side wall of the inner container.

[0006] In the aforementioned cooking appliance, when the inner pot is placed on the heating plate, the bottom wall of the inner pot is in contact with the upper surface of the heating plate, allowing the heating plate to directly heat the bottom wall of the inner pot. Simultaneously, the force-applying component abuts against the heat-conducting component and applies force to it, causing the heat-conducting component to rotate around its axis of rotation via the connecting component and come into contact with the side wall of the inner pot. The heat-conducting component then conducts the heat generated by the heating plate to the side wall of the inner pot, heating it and ensuring even heating, thus improving heating efficiency and shortening cooking time. Even if different inner pots have different sizes due to large dimensional tolerances or processing errors, the force-applying component ensures effective contact between the heat-conducting component and the side wall of the inner pot of varying sizes, guaranteeing heat conduction between the heat-conducting component and the inner pot. This also expands the applicability of the cooking appliance.

[0007] In one embodiment, the heat-conducting element includes a heat transfer portion and a heat-conducting portion connected to the heat transfer portion, the heat transfer portion being disposed on the lower surface of the heating plate, and at least a portion of the heat-conducting portion being disposed on the outer side wall of the inner liner.

[0008] With this configuration, the heat generated by the heating plate can be conducted through the heat transfer part to the heat conduction part, and then through the heat conduction part to the outer wall of the inner liner.

[0009] In one embodiment, the heat transfer portion is shaped to fit the lower surface of the heating plate; and / or the heat conduction portion is curved to fit the shape of the inner liner sidewall.

[0010] This configuration allows the heat transfer part to fit snugly against the lower surface of the heating plate, ensuring effective heat conduction between the heating plate and the side wall of the heat transfer part; it also allows the heat conduction part to fit snugly against the side wall of the inner liner, ensuring effective heat conduction between the heat conduction part and the side wall of the inner liner.

[0011] In one embodiment, the connector includes a mounting base and a rotating shaft. The mounting base is disposed on the lower surface of the heating plate and has a shaft hole. The heat transfer part has an assembly hole. The mounting base is movably inserted through the assembly hole and protrudes from the shaft hole. The rotating shaft is inserted through the shaft hole and is the rotation axis of the heat-conducting component.

[0012] This configuration prevents the mounting base from accidentally dislodging from the assembly hole, and allows the heat-conducting component to rotate around the shaft relative to the mounting base and heating plate.

[0013] In one embodiment, the connector includes a mounting base and a rotating shaft. The mounting base has a shaft hole, and the rotating shaft is disposed in the heat transfer part. The rotating shaft is rotatably engaged with the shaft hole, and the rotating shaft is the rotation axis of the heat conduction component.

[0014] With this configuration, the heat-conducting component is rotatably connected to the mounting base via a rotating shaft, and the heat-conducting component can rotate around the rotating shaft relative to the mounting base and the heating plate.

[0015] In one embodiment, the force-applying element is an elastic element, which is located below the heat-conducting element and on the side of the connector near the edge of the heating plate. One end of the elastic element is connected to the outer shell, and the other end is connected to the lower surface of the heat-conducting element.

[0016] With this configuration, the elastic element is compressed after the inner liner is inserted, and an elastic force is applied to the heat-conducting element towards the inner liner to press the heat-conducting element tightly against the side wall of the inner liner, so that the heat-conducting part is in close contact with the side wall of the inner liner, ensuring the heat conduction effect between the heat-conducting element and the side wall of the inner liner.

[0017] In one embodiment, the force-applying element is an elastic element, which is disposed between the heat-conducting element and the heating plate, and is located on the side of the connector near the center of the heating plate.

[0018] With this configuration, the elastic element is compressed after the inner liner is inserted, and an elastic force is applied to the heat-conducting element in a direction away from the inner liner to press the heat-conducting part tightly against the side wall of the inner liner, so that the heat-conducting part and the side wall of the inner liner are in close contact, ensuring the heat conduction effect between the heat-conducting part and the side wall of the inner liner.

[0019] In one embodiment, there are multiple heat-conducting components arranged circumferentially along the heating plate.

[0020] This configuration allows multiple heat-conducting components to increase the contact area between the heat-conducting components and the inner liner sidewall, thereby improving heating efficiency.

[0021] In one embodiment, a plurality of the heat-conducting components are evenly distributed along the circumference of the heating plate.

[0022] This design ensures uniform heating of the inner liner's sidewalls, further improving heating efficiency and effectiveness.

[0023] In one embodiment, the inner liner is made of ceramic material.

[0024] This setting allows the ingredients to retain their original flavor and improves the cooking results. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Existing cooking appliances, such as electric slow cookers, include a heating base, a pot body, and an inner pot. The inner pot is located inside the pot body and rests on the heating base, thus heating the food inside. The inner pot is usually made of ceramic. While ceramic can preserve the original flavor of the food, its low thermal conductivity means that the heat generated by the heating element on the heating base cannot effectively heat the food inside the inner pot. As a result, a significant amount of heat is lost through the bottom of the heating element to the surrounding area, leading to low heating efficiency and long cooking times.

[0039] Although existing cooking utensils have side heating / heat conduction structures attached to the side walls of earthenware pots, the pot body is made of ceramic and has large dimensional tolerances. When the side heating / heat conduction structure heats or keeps the earthenware pot's side warm, a certain gap must be reserved between the side structure and the side of the earthenware pot during the design process. This is to accommodate the various deformations of the earthenware pot so that it cannot make effective contact with the side of the earthenware pot. The heat can only be heated to the earthenware pot by radiation, resulting in low side heating efficiency and long cooking time.

[0040] To solve the above problems, such as Figures 1 to 9 As shown, this application provides a cooking appliance to ensure effective contact between the heat-conducting component and the inner pot sidewall. This cooking appliance can be an electric slow cooker, electric stew pot, or other cooking equipment.

[0041] like Figures 1 to 2 As shown, specifically, the cooking appliance includes a heating base 10, an inner pot 20, and at least one heat-conducting component 30, wherein: the heating base 10 includes a housing 11 and a heating plate 12 disposed within the housing 11; the inner pot 20 can be disposed within the housing 11 and placed on the upper surface of the heating plate 12; each heat-conducting component 30 includes a heat-conducting element 31, a connecting element 32, and a force-applying element 33, the heat-conducting element 31 is rotatably disposed on the edge of the heating plate 12 via the connecting element 32, and has a rotation axis; the force-applying element 33 abuts against the heat-conducting element 31 to apply a force to drive the heat-conducting element 31 to rotate around the rotation axis to fit against the side wall of the inner pot 20.

[0042] In the cooking appliance provided in this application, when the inner pot 20 is placed on the heating plate 12, the bottom wall of the inner pot 20 is in contact with the upper surface of the heating plate 12, so that the heating plate 12 can directly heat the bottom wall of the inner pot 20. At the same time, the force-applying member 33 abuts against the heat-conducting member 31 and can apply force to the heat-conducting member 31, so that the heat-conducting member 31 rotates around the rotation axis through the connecting member 32 and is in contact with the side wall of the inner pot 20. The heat-conducting member 31 can conduct the heat generated by the heating plate 12 to the side wall of the inner pot 20 to heat the side wall of the inner pot 20, thereby making the inner pot 20 heated evenly, improving heating efficiency, and shortening cooking time. Furthermore, even if different inner pots 20 have different sizes due to factors such as large dimensional tolerances or processing errors, the force-applying member 33 can ensure that the heat-conducting member 31 is in effective contact with the side wall of the inner pot 20 of different sizes, thereby ensuring the heat conduction effect between the heat-conducting member 31 and the inner pot 20, and also expanding the applicability of the cooking appliance.

[0043] The heat-conducting component 31 is made of a metal material with good thermal conductivity, such as aluminum, to effectively transfer the heat generated by the heating plate 12 to the side wall of the inner liner 20.

[0044] In one embodiment, the inner pot 20 is made of ceramic material. The ceramic material allows the food to retain its original flavor, and the heating plate 12 and heat-conducting component 30 work together to heat both the bottom and side walls of the inner pot 20, ensuring that the heat generated by the heating plate 12 effectively heats the food inside the inner pot 20, thereby improving the cooking effect. Of course, in other embodiments, the inner pot 20 can also be made of other materials such as stainless steel or aluminum alloy; this embodiment of the invention does not impose specific limitations.

[0045] like Figures 2 to 3 As shown, the heat-conducting component 31 includes a heat transfer portion 311 and a heat-conducting portion 312 connected to the heat transfer portion 311. The heat transfer portion 311 is disposed on the lower surface of the heating plate 12, and at least a portion of the heat-conducting portion 312 is disposed on the outer side wall of the inner liner. The heat transfer portion 311 is connected to the lower surface of the heating plate 12 via a connector 32, allowing the entire heat-conducting component 31 to rotate relative to the heating plate 12 about a rotation axis via the connector 32. The heat-conducting portion 312 is used to contact the outer side wall of the inner liner 20. The heat generated by the heating plate 12 can be conducted through the heat transfer portion 311 to the heat-conducting portion 312, and then through the heat-conducting portion 312 to the side wall of the inner liner 20.

[0046] like Figures 2 to 3As shown, the heat transfer part 311 is shaped to fit the lower surface of the heating plate 12, allowing it to adhere to the lower surface of the heating plate 12 and ensuring effective heat conduction between the heating plate 12 and the sidewall of the heat transfer part 311. Similarly, the heat conduction part 312 is curved to fit the shape of the sidewall of the inner liner 20, allowing it to adhere to the sidewall of the inner liner 20 and ensuring effective heat conduction between them. Since the dimensional differences between different inner liners 20 are usually small, the rotation range of the heat conduction part 31 is also small, ensuring that at least a portion of the heat transfer part 311 is always in contact with the lower surface of the heating plate 12, and at least a portion of the heat conduction part 312 is always in contact with the sidewall of the inner liner 20.

[0047] In one embodiment, the heat transfer part 311 and the heat conduction part 312 are integrally formed, which facilitates the transmission between the heat transfer part 311 and the heat conduction part 312, and is easy to manufacture. Furthermore, the heat conduction part 31 is in the form of a sheet to better transfer heat.

[0048] like Figure 3 and Figure 5 As shown, in one embodiment, the connector 32 includes a mounting base 321 and a rotating shaft 322. The mounting base 321 is disposed on the lower surface of the heating plate 12, and has a shaft hole 3211. The heat transfer part 311 has an assembly hole 3111. The mounting base 321 movably passes through the assembly hole 3111 and protrudes from the shaft hole 3211. The rotating shaft 322 passes through the shaft hole 3211 and serves as the rotation axis of the heat-conducting component 31. The size of the assembly hole 3111 is slightly larger than the size of the mounting base 321, allowing the mounting base 321 to move within the assembly hole 3111. During assembly, the mounting base 321 is first passed through the mounting hole 3111, and then the rotating shaft 322 is passed through the shaft hole 3211. The rotating shaft 322 prevents the mounting base 321 from accidentally coming out of the mounting hole 3111, and one side of the heat transfer part 311 is in contact with the rotating shaft 322, allowing the heat conduction element 31 to rotate relative to the mounting base 321 and the heating plate 12 around the rotating shaft 322. During rotation, the mounting base 321 moves within the mounting hole 3111, and the rotating shaft 322 can rotate with the heat conduction element 31, or it can be fixed relative to the mounting base 321 and the heating plate 12.

[0049] Specifically, the rotating shaft 322 includes a rotating portion 3221 and abutment portions 3222 located at both ends of the rotating portion 3221. The abutment portions 3222 extend axially along the rotating portion 3221 to prevent the rotating shaft 322 from accidentally dislodging from the shaft hole 3211. Furthermore, the number of mounting seats 321 can be one, two, or more, with multiple mounting seats 321 arranged at intervals along the rotation axis. The mounting holes 3111 are arranged in a one-to-one correspondence with the mounting seats 321. Multiple mounting seats 321 can improve the stability and reliability of the connection between the heat-conducting component 31 and the heating plate 12.

[0050] In another embodiment, the connector 32 includes a mounting base 321 and a rotating shaft 322. The mounting base 321 has a shaft hole 3211, and the rotating shaft 322 is disposed in the heat transfer part 311. The rotating shaft 322 is rotatably engaged with the shaft hole 3211, and the rotating shaft 322 is the axis of rotation of the heat-conducting component 31. The heat-conducting component 31 is rotatably connected to the mounting base 321 via the rotating shaft 322, and the heat-conducting component 31 can rotate around the rotating shaft 322 relative to the mounting base 321 and the heating plate 12. The mounting base 321 can be disposed on the lower surface of the heating plate 12 or on the outer casing 11.

[0051] like Figures 4 to 5 As shown, in one embodiment, the force-applying member 33 is an elastic member, located below the heat-conducting member 31 and on the side of the connecting member 32 near the edge of the heating plate 12. One end of the elastic member is connected to the outer shell 11, and the other end is connected to the lower surface of the heat-conducting member 31. When the inner liner 20 is not inserted, the elastic member is in an undeformed state. The size of the inserted inner liner 20 needs to be equal to or larger than the size of the space enclosed by the heat-conducting part 312 and the heating plate 12 at this time, so as to ensure that the heat-conducting part 312 can fit against the side wall of the inner liner 20. After the inner liner 20 is inserted, the heat-conducting component 31 will rotate around the rotation axis in the -X direction. The elastic component is compressed and an elastic force is applied to the heat-conducting component 31 towards the inner liner 20. Since the elastic component is located on the side of the connector 32 near the edge of the heating plate 12, the heat-conducting component 31 as a whole tends to rotate around the rotation axis in the +X direction, so as to press the heat-conducting part 312 tightly against the side wall of the inner liner 20, so that the heat-conducting part 312 and the side wall of the inner liner 20 are closely attached, ensuring the heat conduction effect between the heat-conducting component 31 and the side wall of the inner liner 20.

[0052] like Figures 6 to 9 As shown, in another embodiment, the force-applying member 33 is an elastic member, which is disposed between the heat-conducting member 31 and the heating plate 12, and is located on the side of the connector 32 near the center of the heating plate 12. When the inner liner 20 is not inserted, the elastic member is in an undeformed state. The size of the inserted inner liner 20 needs to be equal to or greater than the size of the space enclosed by the heat-conducting part 312 and the heating plate 12 at this time, so as to ensure that the heat-conducting part 312 can fit against the side wall of the inner liner 20. After the inner liner 20 is inserted, the heat-conducting component 31 will rotate around the rotation axis in the -X direction. The elastic component is compressed and an elastic force is applied to the heat-conducting component 31 in a direction away from the inner liner 20. Since the elastic component is located on the side of the connector 32 near the center of the heating plate 12, the heat-conducting component 31 has a tendency to rotate around the rotation axis in the +X direction, so as to press the heat-conducting part 312 tightly against the side wall of the inner liner 20, so that the heat-conducting part 312 and the side wall of the inner liner 20 are closely attached, ensuring the heat conduction effect between the heat-conducting component 31 and the side wall of the inner liner 20.

[0053] Specifically, the elastic element can be a spring. When one end of the spring is connected to the outer shell 11 and the other end is connected to the lower surface of the heat-conducting element 31, a limiting post 13 protrudes from the inner wall of the outer shell 11. One end of the spring is fitted onto the limiting post 13 to fix one end of the spring to the outer shell 11. At the same time, the limiting post 13 can also limit the deformation direction of the spring. The other end of the spring abuts against the lower surface of the heat transfer part 311. The lower surface of the heat transfer part 311 can also have a limiting post 13 protruding away from the heating plate 12. The two ends of the spring are respectively fitted onto the two limiting posts 13. When the spring is located between the heat-conducting element 31 and the heating plate 12, a limiting post 13 protrudes from the lower surface of the heating plate 12. One end of the spring is fitted onto the limiting post 13 to fix one end of the spring to the heating plate 12. At the same time, the limiting post 13 can also limit the deformation direction of the spring. The other end of the spring abuts against the heat transfer part 311. The heat transfer section 311 may also have protruding limiting posts 13 facing the heating plate 12, and the two ends of the spring are respectively sleeved on the two limiting posts 13. Of course, the elastic element can also be a silicone element, a rubber element, a disc spring, or other elastic elements, and this embodiment of the invention does not impose specific limitations here.

[0054] In other embodiments, the force-applying member 33 may also directly cooperate with the heat-conducting part 312. For example, the force-applying member 33 may be able to extend and retract to abut against the heat-conducting part 312 so that the heat-conducting part 312 fits against the side wall of the inner liner 20.

[0055] In other embodiments, the force-applying member 33 may include two elastic members, one of which is connected at one end to the outer shell 11 and at the other end to the lower surface of the heat-conducting member 31; the other elastic member is disposed between the heat-conducting member 31 and the heating plate 12. Of course, the force-applying member 33 may also be configured as other elements capable of applying force to the heat-conducting member 31, and at least after the inner liner 20 is inserted, it may cause the heat-conducting member 31 to have a tendency to rotate in the +X direction.

[0056] like Figure 3 and 5 As shown, the heat transfer section 311 includes an assembly section 3112 and a heat transfer section 3113. The heat transfer section 3113 is located between the assembly section 3112 and the heat conduction section 312, and at least partially adheres to the lower surface or side surface of the heating plate 12. The assembly section 3112 is used to connect the heat transfer section 3113 and the heat conduction section 312 to the heating plate 12. The heat transfer section 3113 adheres at least partially to the lower surface or side surface of the heating plate 12, so that the heat generated by the heating plate 12 can be conducted through the heat transfer section 3113 to the heat conduction section 312, and then through the heat conduction section 312 to the side wall of the inner liner 20.

[0057] Specifically, the heat transfer section 3113 is located near the edge of the heating plate 12, and the assembly section 3112 extends from the heat transfer section 3113 toward the center of the heating plate 12. The area near the center of the heating plate 12 is the main heating area. Thus, the assembly section 3112 and the heat transfer section 3113 can also reduce the heat generated by the heating plate 12 from spreading to the bottom or the periphery, reduce heat waste, improve heating efficiency, and also prevent the temperature of other components inside the outer casing 11 from rising, avoid risks, and ensure the safety of using the cooking appliance.

[0058] like Figure 3 and Figure 7 As shown, there are multiple heat-conducting components 30, which are arranged circumferentially along the heating plate 12. Multiple heat-conducting components 30 increase the contact area between the entire heat-conducting component 30 and the side wall of the inner liner 20, thereby further improving heating efficiency. Preferably, the multiple heat-conducting components 30 are evenly distributed circumferentially along the heating plate 12, ensuring uniform heating of the side wall of the inner liner 20, thus further improving heating efficiency and heating effect. Specifically, the number of heat-conducting components 30 can be six as shown in the figure, with the six heat-conducting components 30 evenly spaced circumferentially along the heating plate 12. Of course, the number of heat-conducting components 30 can also be two, three, four, or more, as long as the heat-conducting elements 31 of each heat-conducting component 30 do not interfere with each other when rotating relative to the heating plate 12. This embodiment of the invention does not impose specific limitations here.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
