Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a pot base structure and cooking utensil. Background Technology

[0002] Most cooking utensils consist of a pot stand and a pot body that is mounted and supported on the pot stand. The pot stand is mainly formed by the base, the pot body, and the middle plate, with the heating plate installed on the middle plate. During assembly, the heating plate needs to be fixed to the middle plate, the middle plate to the pot body, and the pot body to the base. The entire assembly process is complex and cumbersome, and involves many mating structures.

[0003] In related technologies, to simplify the assembly process and structure, the pot body and base can be integrated into a single structure to form the outer shell. In this case, a support base is located in the lower part of the inner wall of the outer shell, the reflector is mounted and fixed on the support base, and the heating plate and thermometer are respectively mounted on the reflector. This arrangement often results in heat from the heating plate being directly transferred to the outer shell through the support base, causing the outer shell temperature to become excessively high, posing a safety hazard. Utility Model Content

[0004] Therefore, it is necessary to provide a pot base structure to reduce the heat transferred to the support shell via the heating plate, and avoid overheating of the support shell to prevent safety hazards.

[0005] A pot base structure includes a supporting shell, a heating component, and a heat insulation seat; the supporting shell has an integrally formed side wall and a bottom wall, the side wall and the bottom wall together forming a cavity, and the cavity wall of the cavity is provided with a support seat; the heating component is housed in the cavity; the heat insulation seat is disposed between the heating component and the support seat, for preventing the heat from the heating component from being transferred to the support seat.

[0006] Understandably, a support base is used to assemble the heating element relative to the support housing, with a heat insulation seat between the support base and the heating element. This arrangement not only prevents the heating element from directly contacting the support base, but also, by utilizing the heat insulation properties of the heat insulation seat, reduces the heat transferred from the heating element to the support base, thereby reducing the heat transferred to the support housing and preventing the support housing temperature from becoming too high.

[0007] In some embodiments, the heat insulation base includes a first connecting portion and a second connecting portion, the first connecting portion being connected to the support base, and the second connecting portion supporting and connecting to the heating assembly.

[0008] In other words, the connection between the heat insulation seat and the support seat is improved by cooperating with the first connecting part and the support part, and by cooperating with the heating component through the second connecting part.

[0009] In some embodiments, the first connecting portion and the second connecting portion are spaced apart in the horizontal direction.

[0010] This design effectively disperses and extends the heat transfer path, thereby increasing heat loss during the heat transfer process and significantly reducing the heat ultimately transferred to the support shell, thus reducing safety hazards caused by excessively high temperatures in the support shell.

[0011] In some embodiments, the first connecting portion and the second connecting portion are spaced apart in the vertical direction.

[0012] This design increases the vertical heat diffusion and transfer paths, thereby increasing heat loss during the heat transfer process.

[0013] In some embodiments, the heat insulation seat further includes a main body, the first connecting portion is disposed on the main body, the second connecting portion protrudes from the main body, the protruding end of the second connecting portion is connected to the heating assembly, and the projection of the second connecting portion in the vertical direction is smaller than the projection of the main body in the vertical direction.

[0014] This design ensures a small contact area between the heat insulation base and the reflector, which is equivalent to reducing the heat transfer area and further reducing heat transfer.

[0015] In some embodiments, the heat insulation seat further includes an abutment portion connected to the first connecting portion and / or the second connecting portion, and the edge of the heating assembly can abut against the abutment portion.

[0016] This design avoids deformation of the reflector in the heating assembly and prevents direct contact between the reflector and the supporting housing, further reducing heat transfer.

[0017] In some embodiments, the first connecting portion has a first central axis, the second connecting portion has a second central axis, and the distance between the first central axis and the second central axis is between 5mm and 10mm.

[0018] This design not only ensures that the distance between the first and second connecting parts is sufficient to avoid assembly interference, but also ensures that the overall size of the heat insulation seat is relatively small, reducing the connection area with the supporting shell and reducing heat transfer.

[0019] In some embodiments, the support base includes a base body and a support column protruding from the base body, the support column being connected to the first connecting portion.

[0020] This reduces the contact area between the insulation base and the support base, thus decreasing heat transfer.

[0021] In some embodiments, the first connecting portion is provided with an assembly groove, and the support column is inserted into the assembly groove.

[0022] In other words, by using the insertion and connection of the assembly slot and the support column, the connection reliability between the heat insulation seat and the support seat can be improved.

[0023] In some embodiments, the heat insulation seat further includes a main body, and the first connecting portion and the second connecting portion are both disposed on the main body; the support seat further includes a limiting protrusion protruding from the seat body and adjacent to or spaced apart from the support column, the main body is provided with a limiting groove, and the limiting protrusion is inserted into the limiting groove and abuts against the groove wall of the limiting groove for limiting.

[0024] In other words, by using the upper limit groove of the main body and the limiting protrusion for limiting, not only can the assembly limiting of the heat insulation seat and the main body be satisfied, and the connection reliability and assembly stability of the heat insulation seat and the support seat be enhanced; furthermore, the limiting protrusion can also be used to support the heat insulation seat, so as to more stably support the heating component, and even the pot body placed on the heating component.

[0025] In some embodiments, the heating assembly includes a reflector and a heating plate disposed on the reflector, the outer diameter of the reflector being larger than the outer diameter of the heating plate, and the reflector being detachably connected to the second connecting portion.

[0026] This design avoids direct connection between the heating element and the heat insulation base, reducing the amount of heat transferred directly to the heat insulation base.

[0027] In some embodiments, the second connecting portion is provided as a column, the column extending vertically toward a side away from the first connecting portion, and the extended end of the column abutting against the edge of the reflector.

[0028] This configuration maintains a small contact area between the heat insulation base and the reflector, thereby reducing the heat conduction area and thus reducing the heat transferred to the support housing; moreover, the column configuration enhances the support effect for the heating components.

[0029] In some embodiments, the pot base structure further includes a locking member; the first connecting portion is fixed to the support base via the locking member, and / or the second connecting portion is fixed to the heating assembly via the locking member. This improves connection reliability and ensures connection stability.

[0030] In some embodiments, the inner sidewall of the support housing is provided with a wire-blocking structure that extends toward the center of the cavity to constrain the wire harness in the region of the cavity near the center.

[0031] In other words, by using the wire-blocking structure, the wire harness can be kept away from the water leakage hole, which not only reduces the obstruction of the water leakage hole by the wire harness, but also prevents the wire harness from being exposed from the water leakage hole and easily damaged.

[0032] In some embodiments, the support housing is further provided with a power cord socket communicating with the cavity, and the pot base structure further includes a power cord pressure plate, which is detachably connected to the support housing and seals the power cord socket.

[0033] In other words, by using the power cord clamp, not only can the wire harness be prevented from being exposed from the power socket, but it can also work with the support housing to limit the power cord and ensure connection reliability.

[0034] One embodiment of this application also provides a cooking appliance, including a pot body and the aforementioned pot base structure, wherein the pot body is placed in the heating component of the pot base structure and is at least partially accommodated within the cavity.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0051] In related technologies, pot supports typically consist of a base, a pot body, and a middle plate. The middle plate is connected to the upper part of the pot body, and the base is connected to the lower part of the pot body. The middle plate and the pot body, as well as the base and the pot body, are secured with snap-fit ​​connections, further tightened by multiple spaced screws to ensure assembly reliability. This results in a complex assembly process with numerous components requiring coordination.

[0052] In related technologies, the pot body and base are typically molded as a single unit to form the outer shell, saving on the fitting structure and assembly process between the pot body and the base. Furthermore, a support base is located in the lower middle part of the inner wall of the outer shell, and the heating structure is mounted on the support base via a reflector to support the heating plate and the pot body, thus eliminating the need for a separate middle plate and saving on the fitting structure and assembly process between the middle plate and the pot body. However, this design allows the heat generated by the heating plate to be directly transferred to the outer shell through direct contact between the reflector and the outer shell, causing the outer shell temperature to become excessively high, posing a safety hazard.

[0053] Based on this, please refer to Figures 1 to 6This application provides a pot support structure 100 for supporting a pot body and heating food inside the pot via electric heating for cooking. The pot support structure 100 reduces the heat transferred to the outer shell (i.e., the supporting shell 110) via the heating plate, preventing overheating and potential safety hazards. Specifically, the pot support structure 100 includes a supporting shell 110, a heating element 120, and a heat insulation seat 130. The supporting shell 110 has an integrally formed side wall 1105 and bottom wall 1106, which together form a cavity 1101. The cavity wall of the cavity 1101 is provided with a support seat 111, and the heating element 120 is housed within the cavity 1101. The heat insulation seat 130 is located between the heating element 120 and the support seat 111 to prevent heat from the heating element 120 from being transferred to the support seat 111. In this design, both the sidewall 1105 and the bottom wall 1106 facing the cavity 1101 serve as the cavity wall of the cavity 1101. For example, a support seat 111 may be provided at the lower part of the sidewall 1105, or near the edge of the bottom wall 1106, or near the middle of the bottom wall 1106, or both the lower part of the sidewall 1105 and the middle part of the bottom wall 1106 may be provided with support seats 111. This is merely an example.

[0054] The supporting shell 110 has a U-shaped cross-section along the vertical direction, which allows for an integrated design of the base and the pot body, reducing assembly structure and process. The vertical direction is... Figure 1 The support base 111 can be located in the lower middle part of the support housing 110. Thus, when the heating component 120 is installed on the support base 111 via the heat insulation seat 130, the heating component 120 can be entirely housed within the cavity 1101, and the lower part of the pot body placed on the heating component 120 can also be housed within the cavity 1101. This serves to limit the assembly of the pot body relative to the pot base structure 100, reducing pot body wobbling. In this process, the heat insulation seat 130 between the heating component 120 and the support base 111 not only prevents the heating component 120 from directly contacting the support base 111, but also, through its heat insulation properties, blocks the heat directly transferred from the heating component 120 to the support base 111, thereby reducing the heat transferred to the support housing 110 via the support base 111 and preventing safety hazards caused by excessively high temperatures in the support housing 110.

[0055] In some specific embodiments, the support base 111 is located at the lower part of the side wall 1105. Multiple support bases 111 are provided and arranged at circumferential intervals along the support housing 110. Each support base 111 is connected to the edge of the heating assembly 120 via a heat insulation seat 130. For example, three support bases 111 are provided, with any two adjacent support bases 111 spaced 120° apart, thus improving support stability while meeting support requirements.

[0056] Please continue reading. Figures 1 to 6 In some embodiments, the heat insulation base 130 includes a first connecting portion 131 and a second connecting portion 132. The first connecting portion 131 is connected to the support base 111, and the second connecting portion 132 supports and connects to the heating assembly 120. That is, the heat insulation base 130, through the arrangement of the first connecting portion 131 and the second connecting portion 132, satisfies the requirement of contact-type engagement with the support base 111 and the heating assembly 120, thereby improving connection reliability and support stability. The first connecting portion 131 and the support base 111 can be directly connected or indirectly connected through other structures; similarly, the assembly of the second connecting portion 132 with the heating assembly 120 is similar.

[0057] In some embodiments, the first connecting portion 131 and the second connecting portion 132 are spaced apart in the horizontal direction. For example... Figure 3 and Figure 4 In this configuration, the first connecting portion 131 is located on the right side, and the second connecting portion 132 is located on the left side. That is, the first central axis of the first connecting portion 131 and the second central axis of the second connecting portion 132 are not collinear, causing the portion of the heat insulation base 130 used to connect the support base 111 and the portion used to connect the heating assembly 120 to be located in different areas. For example, the first connecting portion 131 and the second connecting portion 132 are arranged circumferentially at intervals along the support housing 110. This arrangement effectively disperses and lengthens the heat transfer path from the self-heating assembly 120 to the support base 111, thereby increasing heat loss during heat transfer and significantly reducing the heat ultimately transferred to the support housing 110.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the heating assembly 120 includes a reflector 121 and a heating plate 122 disposed on the reflector 121, the heating plate 122 being provided with a heating tube 123. The heating plate 122 can be fixed to the reflector 121 with screws or welded to the reflector 121, as long as a reliable connection between the heating plate 122 and the reflector 121 is ensured. The outer diameter of the reflector 121 is larger than the outer diameter of the heating plate 122, and the edge of the reflector 121 is connected to the second connecting portion 132 of the heat insulation base 130, avoiding direct connection between the heating plate 122 and the heat insulation base 130, thus reducing the heat directly transferred to the heat insulation base 130. The heating assembly 120 also includes a thermometer 125 disposed on the heating plate 122.

[0059] In some embodiments, the pot base structure 100 further includes a locking member (not shown in the figure). The first connecting portion 131 is fixed to the support base 111 by the locking member, and the second connecting portion 132 is fixed to the heating assembly 120 by the locking member, specifically fastened to the edge of the reflector 121 to maintain assembly stability. Since the first connecting portion 131 and the second connecting portion 132 are spaced apart in the horizontal direction, contact or interference between the two locking members can be avoided, thereby further reducing heat transfer and maintaining assembly reliability.

[0060] In some specific embodiments, the locking element can be directly a screw, that is, the first connecting part 131 is fixed to the support base 111 by a screw, and the second connecting part 132 is fixed to the edge of the reflector 121 by a screw. In this case, by using the first connecting part 131 and the second connecting part 132 to be spaced apart in the horizontal direction, sufficient assembly space is provided for the assembly of the two screws, avoiding interference between the two, and possibly avoiding the problem of heat conduction caused by direct contact between the two screws.

[0061] Alternatively, the first connecting part 131 can also be snapped or bonded to the support base 111; and the second connecting part 132 can be bonded to the edge of the reflector 121 by screws, or welded to the edge of the reflector 121, or snapped on. It is sufficient that the first connecting part 131 and the second connecting part 132 are spaced apart in the horizontal direction and reliably connected to the support base 111 and the reflector respectively.

[0062] like Figures 3 to 4 As shown, in some embodiments, the first connecting portion 131 has a first central axis, and the second connecting portion 132 has a second central axis. The first and second central axes are arranged parallel to each other, and the distance L1 between them is not less than 5 mm. Taking screw fixing as an example, the first connecting portion 131 is provided with a first mounting hole 1301 for screw assembly, and the first central axis is the axis of the first mounting hole 1301; and the second connecting portion 132 is provided with a second mounting hole 1302 for screw assembly, and the second central axis is the axis of the second mounting hole 1302. Therefore, by limiting the distance between the two central axes, on the one hand, sufficient space can be provided for the setting of the first mounting hole 1301 and the second mounting hole 1302, thereby ensuring the size of the corresponding screws to meet the connection reliability; on the other hand, it can avoid the problem of easy interference or contact leading to heat transfer due to the small distance between the corresponding screws.

[0063] Furthermore, the distance between the first central axis and the second central axis is no greater than 10mm. This arrangement avoids the problem of the heat insulation seat 130 becoming too large and its strength decreasing due to the large distance between the first connecting part 131 and the second connecting part 132; and the smaller size will also reduce the connection area with the supporting shell 110, thereby reducing the heat transfer area.

[0064] In some specific embodiments, the distance between the first central axis and the second central axis is between 5mm and 8mm. This arrangement not only ensures that the distance between the first connecting portion 131 and the second connecting portion 132 is sufficient to avoid interference between the two screws, but also ensures that the overall size of the heat insulation seat 130 is relatively small, with higher structural strength, making it a better transfer structure to support the heating assembly 120. For example, the distance between the first central axis and the second central axis can be 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, or 8mm, etc.

[0065] Alternatively, the first and second central axes can be set at an angle. In this case, the distance between the first and second central axes gradually decreases from top to bottom. The key is to ensure that the assembly of the first connecting part 131 with the support base 111 and the assembly of the second connecting part 132 with the heating assembly 120 do not interfere with or come into contact with each other.

[0066] Please see Figures 1 to 5 In some embodiments, the first connecting portion 131 and the second connecting portion 132 are spaced apart in the vertical direction. For example, the first connecting portion 131 may be located below the second connecting portion 132. This arrangement increases the heat diffusion and transfer path in the vertical direction, thereby increasing heat loss during heat transfer and reducing the heat transferred to the support housing 110.

[0067] In some specific embodiments, the first connecting portion 131 and the second connecting portion 132 are spaced apart in the horizontal direction and in the vertical direction. This not only increases the heat diffusion and transfer path in the horizontal direction, but also increases the heat diffusion and transfer path in the vertical direction, thereby significantly reducing the heat transferred to the support housing 110, keeping the support housing 110 as low a temperature as possible, and improving safety in use.

[0068] Alternatively, the second connecting part 132 can be located below the first connecting part 131.

[0069] In this configuration, when the first connecting portion 131 is located below the second connecting portion 132, the upper part of the second connecting portion 132 can contact the bottom of the reflector 121 and be locked by screws. Alternatively, when the first connecting portion 131 is located below the second connecting portion 132, a mounting post can be provided protruding downwards at the edge of the reflector 121. The mounting post corresponds to the second connecting portion 132 and is fixed to the second connecting portion 132 by a long screw passing through the reflector 121 and the mounting post. Of course, it is also possible that the screw passes through the second connecting portion 132 and connects to the mounting post, and the mounting post is welded to the reflector 121. This is only an example.

[0070] In other embodiments, the first connecting portion 131 and the second connecting portion 132 are flush. In this case, the distance between the first central axis and the second central axis can be increased accordingly. This is only an example.

[0071] In another embodiment, the first connecting portion 131 and the second connecting portion 132 are coaxial and spaced apart in the vertical direction. An additional spacer may be provided between the first connecting portion 131 and the second connecting portion 132 to avoid direct contact between the first connecting portion 131 and the second connecting portion 132, thereby further improving the heat insulation effect.

[0072] In another embodiment, the first connecting portion 131 and the second connecting portion 132 can also be coaxial and directly connected. In this case, the first connecting portion 131 is located below the second connecting portion 132, and the end of the first connecting portion 131 facing away from the second connecting portion 132 in the vertical direction is engaged with the support base 111, while the end of the second connecting portion 132 facing away from the first connecting portion 131 in the vertical direction is engaged with the reflector 121 in the heating assembly 120. Of course, it is also possible that the first connecting portion 131 is engaged with the support base 111, and the second connecting portion 132 is fastened to the reflector 121 by screws; conversely, the first connecting portion 131 is fastened to the support base 111 by screws, and the second connecting portion 132 is engaged with the reflector 121. Alternatively, both the first connecting portion 131 and the second connecting portion 132 are fastened to the support base 111 and the reflector 121 respectively by screws, and the two screws do not contact each other or a heat insulation pad is provided between them. This is only an example for illustration.

[0073] Please continue reading. Figures 1 to 5 In some embodiments, the heat insulation seat 130 further includes a main body 133, a first connecting portion 131 is disposed on the main body 133, for example, the first connecting portion can be part of the main body 133, a second connecting portion 132 protrudes from the main body 133, specifically protruding from the upper surface of the main body 133, the protruding end of the second connecting portion 132 is connected to the heating component 120, and the projection of the second connecting portion 132 in the vertical direction is smaller than the projection of the main body 133 in the vertical direction.

[0074] Specifically, the second connecting portion 132 protrudes vertically upward from the upper surface of the main body 133 and is cylindrical in shape. The protruding end of the second connecting portion 132 abuts against the reflector 121 and is fastened by a locking member. That is, the column extends vertically towards the side away from the first connecting portion 131, and the extended end of the column abuts against the edge of the reflector 121 to reduce the contact area between the heat insulation seat 130 and the reflector 121. When the locking member is a screw, a round hole is punched at the edge of the reflector 121 so that the round hole forms a groove on the side away from the support seat 111 along its own axis. The screw can be a countersunk screw, and the nut is accommodated in the groove to avoid the screw protruding and affecting the support of the pot body. The second connecting portion 132 has a threaded hole extending downward from the protruding end to cooperate with the screw. Due to the difference in projection between the second connecting part 132 and the main body 133, the contact area between the heat insulation seat 130 and the reflector 121 is small, which is equivalent to reducing the heat transfer area and further reducing heat transfer.

[0075] The main body 133, the first connecting part 131, and the second connecting part 132 are all integrally formed, for example, by injection molding. The first connecting part 131 and the second connecting part 132 are spaced apart in the horizontal direction on the main body 133 and spaced apart in the vertical direction.

[0076] Please see Figures 1 to 3 In some embodiments, the heat insulation base 130 further includes an abutment portion 134, which is connected to the first connecting portion 131 and the second connecting portion 132. The edge of the heating assembly 120 can abut against the abutment portion 134, specifically the edge of the reflector 121 abuts against the abutment portion. This arrangement can prevent deformation of the reflector 121 in the heating assembly 120 and prevent direct contact between the reflector 121 and the support housing 110, further reducing heat transfer. The edge of the reflector 121 extends downwards as a flange, which abuts against the abutment portion 134. The abutment portion 134 is arc-shaped to fit the inner wall of the support housing 110. The abutment portion 134 is connected to the main body 133.

[0077] Furthermore, there is a heat-insulating gap between the contact portion 134 and the inner wall of the support housing 110, thereby forming an air thermal resistance and avoiding heat conduction problems caused by direct contact between the contact portion 134 and the support housing 110.

[0078] Please refer to 1. Figure 5 , Figure 6 , Figure 7 and Figure 8In some embodiments, the support base 111 includes a base body 1111 and a support column 1112 protruding from the base body 1111, the support column 1112 being connected to the first connecting portion 131. The base body 1111 is connected to the support housing 110, for example, it can be integrally formed to ensure connection reliability. The base body 1111 has multiple spaced perforated holes, which, while meeting the requirements of lightweight design, also increases the air thermal resistance of the base body 1111 itself, further reducing heat transfer. The support column 1112 protrudes from the top of the base body 1111, and the support column 1112 has threaded holes, facilitating the screw to pass through the first connecting portion 131 and engage with the threaded hole wall. Of course, the base body 1111 can also be arranged in a block shape.

[0079] In some specific embodiments, the first connecting part 131 is provided with an assembly groove 1310. The first connecting part 131 is integrally formed into the main body 133, which is equivalent to the main body 133 having an assembly groove 1310. The support column 1112 is inserted into the assembly groove 1310. That is, the first connecting part 131 is sleeved on the outer periphery of the support column 1112 through the assembly groove 1310. The groove wall of the assembly groove 1310 and the outer wall of the support column 1112 can both be provided with matching grooves and protrusions. The protrusions can be confined within the grooves, thereby increasing the connection reliability between the support column 1112 and the first connecting part 131. The first connecting part 131 is provided with a first assembly hole 1301 communicating with the assembly groove 1310. A screw passes through the first assembly hole 1301 and extends into the threaded hole of the support column 1112 to realize the assembly of the first connecting part 131 and the support base 111. At this time, the main body 133 can also play a role in the initial positioning of the heat insulation seat 130 and the support seat 111 through the insertion and cooperation of the assembly groove 1310 and the support column 1112.

[0080] In other embodiments, the first connecting portion 131 may also be cylindrical. For example, both the first connecting portion 131 and the second connecting portion 132 may be cylindrical and extend in opposite directions in the vertical direction. Specifically, the first connecting portion 131 extends downward and the second connecting portion 132 extends upward. The first connecting portion 131 abuts against the support column 1112 and is locked with screws, and the second connecting portion 132 abuts against the reflector 121 and is locked with screws.

[0081] In yet another embodiment, the second connecting portion 132 is provided with a second mounting groove, and the mounting post at the edge of the reflector 121 is inserted into the second mounting groove.

[0082] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8In some embodiments, the support base 111 further includes a limiting protrusion 1113, which protrudes from the base body 1111 and is adjacent to or spaced apart from the support column 1112. The main body 133 is provided with a limiting groove 1330, and the limiting protrusion 1113 is inserted into the limiting groove 1330 and abuts against the groove wall of the limiting groove 1330 for limiting. This arrangement not only satisfies the assembly limiting of the heat insulation base 130 and the main body 133, enhancing the connection reliability and assembly stability of the heat insulation base 130 and the support base 111; but also allows the limiting protrusion 1113 to support the heat insulation base 130, thereby improving the support effect on the heating component 120 and even its upper pot body. The limiting protrusion 1113 is T-shaped, comprising a transverse segment and a longitudinal segment connected to the middle of the transverse segment. Both sides of the transverse segment abut against the wall of the limiting groove 1330 along its length, and the longitudinal segment extends towards the support column 1112 to enhance the structural strength of the transverse segment. Alternatively, the limiting protrusion 1113 can be a block shape adapted to the size of the limiting groove 1330; or, the limiting protrusion 1113 can include multiple limiting columns spaced apart circumferentially along the limiting groove, each abutting against the wall of the limiting groove 1330. This is merely an example.

[0083] In other embodiments, the limiting groove 1330 is connected to the aforementioned assembly groove 1310. In this case, the limiting protrusion 1113 and the support column 1112 can be integrally formed, and the limiting protrusion 1113 and the support column 1112 cooperate to jointly support the heat insulation seat 130. Of course, the limiting groove 1330 and the assembly groove 1310 may not be connected; this is only an example.

[0084] Alternatively, the main body 133 can also be fixed with screws or snap-fitted to the support base 111. This is merely an example to illustrate the point.

[0085] Please see Figure 7 and Figure 9 In some embodiments, the inner side of the support housing 110 is also provided with a wire-blocking structure 112, which extends toward the center of the cavity 1101 to constrain the wire harness in the area near the center of the cavity 1101.

[0086] Specifically, the support housing 110 has a drainage hole near its bottom edge, which connects to the recess 1101; and the bottom of the support housing 110 has a plurality of support legs 113 arranged at intervals along its circumference. Therefore, the wire-blocking structure 112 can prevent the wire harness from approaching the drainage hole, which not only reduces the obstruction of the drainage hole by the wire harness, but also prevents the wire harness from being exposed from the drainage hole and easily damaged.

[0087] Furthermore, the bottom of the support housing 110 is provided with a plurality of heat dissipation holes 1103 arranged at intervals along its circumference and connected to the cavity 1101 to ensure good heat dissipation effect.

[0088] Please see Figure 1 , Figure 6 , Figure 7 and Figure 9 In some embodiments, the support housing 110 is further provided with a power cord socket 1102 communicating with the cavity 1101. The pot base structure 100 also includes a power cord pressure plate 140, which is detachably connected to the support housing 110 and seals the power cord socket 1102.

[0089] In practical use, the pot base structure 100 also includes a function indicator panel 160, which is located in the support housing 110 and electrically connected to the wiring harness in the recess 1101. This wiring harness is also electrically connected to the heating assembly 120 and the power cord 150 to meet the electric heating requirements of the heating assembly 120. Therefore, the power cord clamping plate 140 not only prevents the wiring harness from being exposed at the power socket but also works with the support housing 110 to limit the power cord 150, ensuring reliable connection. The power cord clamping plate 140 can be fixed to the support housing 110 with screws and has ventilation holes to ensure effective heat dissipation.

[0090] The support housing 110 is provided with a mounting hole 1104 communicating with the cavity 1101, and the function indicator panel 160 is mounted in the mounting hole 1104.

[0091] In some embodiments, the heating element 120 has a through hole in the center of its heating plate 122. The heating element 120 also includes a support portion 124, which is at least partially located within the through hole. The support portion 124 is convex in shape, with its center extending into the through hole and its edge abutting against the bottom of the heating plate 122. The support portion 124 is welded to the heating plate 122. This configuration effectively reduces the size of the heating plate 122, thereby saving costs.

[0092] The support housing 110 has a flanged edge at the opening edge and a lifting part 114 to facilitate the user to lift the pot base structure 100.

[0093] One embodiment of this application also provides a cooking appliance, including a pot body and the aforementioned pot base structure 100. The pot body is placed in the heating element 120 of the pot base structure 100 and is at least partially accommodated in the cavity 1101. The bottom surface of the pot body is in contact with the upper surface of the heating element 120 to facilitate sufficient heat transfer.

[0094] The cooking appliance can be a multi-functional cooking pot, an electric hot pot, or a small saucepan, etc.

[0095] 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.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
