Description

Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to an electric hot pot. Background Technology

[0002] Existing electric hot pots, such as electric hot pots and electric slow cookers, generally include a heating device, an outer pot, and an inner pot that can be placed inside the outer pot. During operation, while the heating device provides heat to the inner pot, it can also easily create a high-temperature environment between the outer and inner pots. When the outer pot absorbs too much heat, it will be at a high temperature. The outer pot of existing electric hot pots is generally made of high-temperature resistant plastic. When it is at a high temperature, it will emit a plastic smell, which will affect the user experience. Moreover, the outer pot at a high temperature is not easy for users to touch.

[0003] Patent document CN203987545U discloses an electric pressure cooker in which the outer pot and the outer casing are separated by multiple independent heat insulation elements spaced apart along the circumference of the outer pot. Figure 1 As can be seen, the outer cover has a heat-insulating edge on the side closest to the inner cavity of the electric pressure cooker. This heat-insulating edge extends downwards as much as possible to cover the gap between the outer pot and the outer cover, thereby improving the waterproof effect. Although this method achieves waterproofing to a certain extent, the heat-insulating edge of the outer cover is too close to the hot outer pot, which causes a large amount of heat to be transferred from the outer pot to the outer cover during cooking, which is not conducive to forming a good heat insulation effect. This problem is more prominent for some high-power appliances.

[0004] To address the deficiencies in CN203987545U and improve heat insulation, patent document CN215304930U discloses an electric hot pot, including a pot body and an inner pot. The pot body includes an outer shell with a cavity for accommodating the inner pot. A heating unit is disposed within the cavity and located below the inner pot. The pot body also includes an inner shell located within the cavity and surrounding the side of the inner pot, and a reflector located below the heating unit. A first heat insulation gap exists between the reflector and the inner pot, a second heat insulation gap exists between the reflector and the inner shell, and a third heat insulation gap exists between the inner pot and the inner shell. By setting the first, second, and third heat insulation gaps, heat transfer from the high-temperature inner pot and the reflector to the inner shell is reduced. The heat transfer to the outer shell is further reduced by the inner shell, thus solving the problem of excessive temperature rise of the outer shell during cooking.

[0005] Similar to the reflectors or outer pots disclosed in patent documents CN203987545U and CN215304930U, they generally have horizontally extending flanges at their respective rims. To improve the structural strength of the flanges, the edges of the flanges are further flanged again. In order to form a good assembly surface, the direction of the second flange is generally downward, so that the top of the flange is relatively flat, so that the outer pot can fit with the heat insulation component or the outer shell. However, after the flange is flanged downward again, due to the existence of the heat insulation gap, if the pot overflows during operation, it will provide a channel for the overflow water to enter the interior of the outer shell. The interior of the outer shell contains electronic components such as adjustable temperature controllers and control boards. When water droplets fall on the live parts, it will cause circuit failure and lead to abnormal operation of the electric pot. This problem is more pronounced for electric hot pots with heating bases that do not have lids. For example, the inner pot of a detachable hot pot can be placed on the heating base, but the top of the heating base is not covered. During cooking, if the inner pot's lid is not properly closed or if the lid is left open for easy access, the risk of water ingress is greatly increased if the pot overflows. Utility Model Content

[0006] This application provides an electric hot pot that uses an inner gap and an outer barrier to solve the problem that existing electric hot pots cannot adequately balance heat insulation and waterproofing performance. In electric hot pots that are sensitive to both overflow and heat insulation, this application can ensure good heat insulation performance while ensuring that when overflow occurs, overflow water is not easily allowed to enter the outer shell through the gap between the reflector and the inner shell, reducing the technical problems that may cause circuit failure.

[0007] The technical solution adopted in this application is as follows:

[0008] An electric hot pot includes an outer pot, a lid, and an inner pot. The lid closes onto the inner pot by its own weight. The outer pot has a cavity for accommodating the inner pot. The inner pot is removably placed in the cavity. The outer pot includes a shell, a heat-insulating rim connected to the top of the shell and extending downwards, and a reflector located below the heat-insulating rim. The heat-insulating rim and the reflector cooperate to form the cavity. The top of the reflector has an outwardly folded edge. A first heat-insulating gap exists between the lower edge of the heat-insulating rim and the outwardly folded edge. The reflector also has a water-blocking folded edge connected to the outwardly folded edge and extending upwards. The water-blocking folded edge is located outside the heat-insulating rim.

[0009] In this application, the top of the reflector is provided with an outward-flared flange. The presence of the outward-flared flange provides the reflector with a radially outward extension space. When the inner pot overflows, the liquid flowing downward along the outer wall of the inner pot and the inner wall of the heat insulation rim passes through the first heat insulation gap. The extension of the outward-flared flange provides relatively ample radial flow space for the liquid, reducing the probability of the liquid directly flowing into the outer shell through the first heat insulation gap. An upward-extending water-blocking flange is provided on the outward-flared flange, which can further effectively block the liquid, diverting it to flow into the reflector. This further reduces the possibility of liquid entering the outer shell through the first heat insulation gap, thereby effectively protecting the electronic components inside the outer shell and ensuring the normal operation of the electric hot pot.

[0010] The water-blocking flange is connected to the outer periphery of the outer flange and extends continuously along the circumferential direction of the outer periphery of the outer flange to form a closed ring structure.

[0011] In this technical solution, the water-blocking flange extends continuously along the outer periphery to form a closed ring structure. The closed ring structure can block overflowing water from all directions, thereby more effectively protecting the electronic components inside the shell, avoiding short circuits and malfunctions caused by water contacting the circuit, and improving the reliability and safety of the electric hot pot operation.

[0012] The electric hot pot also includes an adjustable temperature controller located inside the outer shell. The adjustable temperature controller is arranged near the outer periphery of the bottom wall of the reflector. The water-blocking flange extends partially along the outer periphery of the outer flange, and at least a portion of the water-blocking flange is located above the adjustable temperature controller.

[0013] This technical solution, by incorporating an adjustable thermostat, allows for a wide range of adjustment in heating power and temperature, meeting the cooking needs of different ingredients and providing a more flexible cooking experience. To facilitate linkage between the adjustable thermostat and an external control knob or sliding switch, the thermostat is positioned relatively far outwards. However, the presence of the first heat insulation gap increases the risk of water ingress into the thermostat. Therefore, this solution places at least a portion of the water-retaining flange above the thermostat, effectively preventing spilled liquid from contacting it and thus protecting it. The partially extended design of the water-retaining flange also reduces the manufacturing cost of the reflector.

[0014] The water-blocking flange tapers inward along the outer flange to shorten the distance between the inner wall of the water-blocking flange and the inner periphery of the outer flange.

[0015] This technical solution shortens the distance between the water-retaining flange and the inner periphery of the outer flange by contracting the water-retaining flange inward along the outer flange. This reduces the accumulation of water on the outer flange at the position corresponding to the water-retaining flange, further reducing the probability of overflowing liquid crossing the water-retaining flange and entering the interior of the shell, thus improving waterproof performance.

[0016] The electric hot pot also includes a heating plate installed on the reflector, the inner pot is supported by the heating plate, the heating plate has a central through hole, and a water-blocking component is provided at the central through hole.

[0017] This technical solution installs the heating plate on the reflector, simplifying the inner pot's structure and facilitating thorough cleaning. Centrifugally cast heating plates are widely used in electric cookers due to their high density and production efficiency. However, due to the manufacturing process, centrifugally cast heating plates often have a central through-hole. When the inner pot overflows, this central through-hole allows spilled liquid to enter the outer pot. Therefore, this technical solution incorporates a water-blocking component at the central through-hole to prevent overflow and reduce the probability of water entering the outer pot. This effectively protects the electronic components inside the outer pot, ensuring the reliability and stability of the electric cooker's operation.

[0018] The electric hot pot also includes a heating plate. The bottom wall of the reflector is provided with a raised area for mounting the heating plate and a sunken area arranged around the raised area. The sunken area is provided with a drain hole.

[0019] If the inner pot overflows, the spilled liquid will collect at the bottom of the reflector. Installing the heating plate in the raised area of ​​the reflector's bottom wall can prevent the heating plate from getting wet, thus reducing the risk of circuit failure. The recessed area facilitates the collection of spilled liquid and its drainage through the drain hole, improving the efficiency of water treatment and enhancing the stability and reliability of the electric cooker's operation.

[0020] There is a second heat insulation gap between the water-blocking flange and the heat insulation edging.

[0021] This technical solution reduces heat transfer from the water-blocking flange to the heat-insulating edge by setting a second heat-insulating gap between the water-blocking flange and the heat-insulating edge, thereby reducing heat transfer from the heat-insulating edge to the outer shell and lowering the temperature rise of the outer shell. This not only prevents the outer shell from becoming too hot to touch, but also extends the service life of the outer shell.

[0022] A heat insulation component is provided between the outer shell and the reflector. The heat insulation component is snapped and fixed to the outward flange. The outer shell is provided with a first positioning post located in the heat insulation space and extending downward. The first positioning post is provided with a first positioning hole. The heat insulation component is provided with a second positioning hole. The reflector and the outer shell are connected by fasteners passing through the second positioning hole and the first positioning hole.

[0023] This technical solution, by placing a heat insulation component between the outer shell and the reflector, avoids contact heat transfer between the reflector and the outer shell, reducing the temperature rise of the outer shell. The heat insulation component is secured to the outward-facing flange via a snap-fit ​​mechanism, facilitating installation and disassembly. The heat insulation component can be assembled onto the reflector without additional tools or complex operations, significantly improving assembly efficiency. Furthermore, the heat insulation component is connected to the outer shell via fasteners. Therefore, the heat insulation component not only reduces heat transfer from the reflector to the outer shell but also provides a medium for the connection between the reflector and the outer shell. The reflector and the outer shell are connected by fasteners passing through the heat insulation component, allowing the reflector, heat insulation component, and outer shell to be assembled as a module with the other components of the electric hot pot, thereby further improving assembly efficiency.

[0024] There are multiple heat insulation elements, and these multiple heat insulation elements are non-uniformly distributed along the outer flange; or...

[0025] There are multiple heat insulation components, which are distributed at equal angles along the outward flange, and the structure of one of the heat insulation components is different from the structure of the other heat insulation components.

[0026] In this technical solution, the non-uniform distribution of the heat insulation components on the outer flange, or the equal-angled arrangement of the heat insulation components on the outer flange but with one heat insulation component having a different structure from the others, gives the multiple heat insulation components specific installation positions in the circumferential direction of the outer flange. This provides clear guidance for the assembly of the reflector and the shell, requiring the reflector and the shell to be assembled with a specific alignment relationship. This ensures the alignment relationship between the water-blocking flange and the internal components of the shell, enabling the water-blocking flange to achieve a better water-blocking effect.

[0027] The outer pot also includes a base located below the outer shell. The base has an upwardly extending second positioning post, the second positioning post has a third positioning hole, the reflector has a fourth positioning hole, and the reflector and the base are connected by fasteners passing through the third positioning hole and the fourth positioning hole.

[0028] In this technical solution, the design of the second positioning post on the base and the third positioning hole on the reflector increases the distance between the base and the reflector, thereby creating a heat dissipation space between them and reducing heat transfer from the reflector to the base. The reflector and the base are connected by fasteners, allowing the module consisting of the reflector, heat insulation component, and outer shell to be assembled together with the base, significantly improving the assembly efficiency of the outer pot. Furthermore, the fastener connection ensures a secure connection between the reflector and the base, reducing potential problems caused by loose components and improving the reliability and stability of the electric hot pot's operation.

[0051] Many specific details are set forth in the following description to provide a thorough understanding of this application.

[0055] like Figures 1 to 4As shown, an electric hot pot includes an outer pot, a lid, and an inner pot 101. The lid is closed onto the inner pot 101 by its own weight. The outer pot has a cavity for accommodating the inner pot 101. The inner pot 101 can be placed in the cavity. The outer pot includes a shell 2, a heat-insulating rim 3 connected to the top of the shell 2 and extending downward, and a reflector 1 located below the heat-insulating rim 3. The heat-insulating rim 3 and the reflector 1 cooperate to form the cavity. The top of the reflector 1 is provided with an outward flange 11. There is a first heat-insulating gap 5 between the lower edge of the heat-insulating rim 3 and the outward flange 11. The reflector 1 is also provided with a water-blocking flange 12 connected to the outward flange 11 and extending upward. The water-blocking flange 12 is located outside the heat-insulating rim 3.

[0056] The heat insulation rim 3 and the reflector 1 form a cavity. During the operation of the electric hot pot, both the inner pot 101 and the reflector 1 radiate heat to the heat insulation rim 3. The presence of the heat insulation space 4 between the heat insulation rim 3 and the outer shell 2, as well as the presence of the first heat insulation gap 5 between the lower edge of the heat insulation rim 3 and the outer flange 11 of the reflector 1, reduces the heat transfer from the heat insulation rim 3 to the outer shell 2, thereby significantly reducing the rate of temperature rise of the outer shell 2.

[0057] In this application, the lid is secured to the inner pot 101 by its own weight, making it possible for the lid to be pushed open when the electric hot pot overflows during high-power cooking. The reflector 1 has an outward-flared edge 11 at its top. This outward-flared edge 11 provides the reflector 1 with radially outward extension space. When the inner pot 101 overflows, the liquid flowing downwards along the outer wall of the inner pot 101 and the inner wall of the heat-insulating edge 3 passes through the first heat-insulating gap 5. The extension of the outward-flared edge 11 provides relatively ample radial flow space for the liquid, reducing the probability of the liquid directly flowing into the outer shell 2 through the first heat-insulating gap 5. An upward-extending water-blocking flange 12 is provided on the outward-flared edge 11, which further effectively blocks the liquid, diverting it to flow into the reflector 1, further reducing the possibility of liquid entering the outer shell 2 through the first heat-insulating gap 5. This effectively protects the electronic components inside the outer shell 2 and ensures the normal operation of the electric hot pot.

[0058] like Figure 4 As shown, the projection of the water-blocking flange 12 on the vertical plane covers at least part of the projection of the first heat insulation gap 5 on the vertical plane, so that the water-blocking flange 12 not only has the function of blocking liquid from entering the interior of the outer shell 2, but also has the function of reducing the heat radiation from the high-temperature inner pot 101 to the outer shell 2 through the first heat insulation gap 5, thereby reducing the temperature rise of the outer shell 2.

[0059] This application does not limit the specific form of the upward extension of the water-retaining flange. For example, the water-retaining flange extends obliquely upwards towards the direction away from the heat insulation edge, thereby widening the gap between the water-retaining flange and the heat insulation edge. This allows the water-retaining flange and the outer flange to form a flared structure along the radial direction of the reflector, enabling the water-retaining flange to buffer the flowing water when there is a large amount of overflow, reducing the probability of overflow entering the interior of the outer shell through the first heat insulation gap. Alternatively, the water-retaining flange extends obliquely upwards towards the direction closer to the heat insulation edge, allowing the water-retaining flange and the outer flange to form a constricted structure along the radial direction of the reflector. When there is a large amount of overflow, the water-retaining flange can block the flowing water and push it back into the interior of the reflector, reducing the probability of overflow entering the interior of the outer shell through the first heat insulation gap. Furthermore, as... Figure 4 As shown, the water-blocking flange 12 extends vertically from bottom to top so that the water-blocking flange 12 and the outer flange 11 can form an equal diameter structure along the radial direction of the reflector 1. The water-blocking flange 12 can maintain a certain gap with the heat insulation circumference 3 and a certain gap with the outer shell 2, thereby reducing the heat transfer to the outer shell 2 through the water-blocking flange 12.

[0060] The specific location of the water-blocking flange 12 in this application can be any of the following embodiments:

[0061] Implementation method one: such as Figure 3 and Figure 6 As shown, the water-blocking flange 12 is connected to the outer periphery of the outer flange 11 and extends continuously along the circumferential direction of the outer periphery of the outer flange 11 to form a closed ring structure. The closed ring structure can form an all-round blockage of overflow water, thereby more effectively protecting the electronic components inside the outer shell 2, avoiding short circuits and malfunctions caused by water contacting the circuit, and improving the reliability and safety of the electric hot pot operation.

[0062] Implementation Method Two: (e.g.) Figure 7 and Figure 8 As shown, the electric hot pot also includes an adjustable temperature controller 10 located inside the outer shell 2. The adjustable temperature controller 10 is arranged near the outer periphery of the bottom wall of the reflector 1. The water-blocking flange 12 extends partially along the outer periphery of the outer flange 11, and at least part of the water-blocking flange 12 is located above the adjustable temperature controller 10.

[0063] This second embodiment, by setting an adjustable thermostat 10, can achieve a wide range of adjustment for heating power and heating temperature, meeting the cooking needs of different ingredients and providing a more flexible cooking experience. To facilitate linkage between the adjustable thermostat 10 and an external operating knob or sliding switch, the adjustable thermostat 10 is positioned relatively far outwards. Due to the presence of the first heat insulation gap 5, the risk of water ingress into the adjustable thermostat 10 is increased. Therefore, in this second embodiment, at least a portion of the water-blocking flange 12 is positioned above the adjustable thermostat 10, effectively preventing overflowing liquid from contacting the adjustable thermostat 10, thus protecting it. Compared to the technical solution in the first embodiment where the water-blocking flange 12 extends continuously along the outer periphery of the outer flange 11, the partial extension design of the water-blocking flange 12 in this second embodiment reduces the processing and manufacturing cost of the reflector 1.

[0064] As a preferred embodiment of this second implementation method, such as Figure 8 As shown, the water-blocking flange 12 contracts inward along the outer flange 11 to shorten the distance between the inner wall of the water-blocking flange 12 and the inner periphery of the outer flange 11.

[0065] In this embodiment, by shrinking the water-blocking flange 12 inward along the outer flange 11, the distance between the water-blocking flange 12 and the inner periphery of the outer flange 11 can be shortened, thereby reducing the accumulation of water on the outer flange 11 at the position corresponding to the water-blocking flange 12, further reducing the probability of overflowing liquid crossing the water-blocking flange 12 and entering the interior of the outer shell 2, and improving the waterproof performance.

[0066] As a preferred embodiment of this application, such as Figure 3 and Figure 7 As shown, the electric hot pot also includes a heating plate 7 installed on the reflector 1, and the inner pot 101 is supported on the heating plate 7. The heating plate 7 has a central through hole, and a water-blocking component 8 is provided at the central through hole.

[0067] In this embodiment, the heating plate 7 is mounted on the reflector 1, which simplifies the structure of the inner pot 101 and facilitates thorough cleaning of the inner pot 101 by the user. The centrifugally cast heating plate 7 has advantages such as high density and high production efficiency, making it widely used in electric hot pots. However, due to the characteristics of the manufacturing process, the centrifugally cast heating plate 7 is prone to having a through-hole in its central area. When the inner pot 101 overflows, this central through-hole provides a path for the overflowing liquid to enter the outer pot. Therefore, in this embodiment, a water-blocking component 8 is provided at the central through-hole to block overflowing water, reducing the probability of it entering the outer pot through the central through-hole. This effectively protects the electronic components inside the outer pot, ensuring the reliability and stability of the electric hot pot's operation.

[0068] In a specific implementation, such as Figure 3As shown, the water baffle 8 includes a blocking part 81 that blocks the central through hole and a positioning part 82 connected to the blocking part 81. The positioning part 82 is connected to the heating plate 7.

[0069] As a preferred embodiment of this application, such as Figure 3 and Figure 6 As shown, the electric hot pot also includes a heating plate 7. The bottom wall of the reflector 1 has a raised area 16 for mounting the heating plate 7 and a sunken area 17 arranged around the raised area 16. The sunken area 17 has a drain hole 15. If the inner pot 101 overflows, the overflowing liquid will converge at the bottom of the reflector 1. Mounting the heating plate 7 on the raised area 16 of the bottom wall of the reflector 1 can prevent the heating plate 7 from being submerged in water, thereby reducing the risk of circuit failure caused by this. The sunken area 17 facilitates the collection of overflowing liquid and its discharge through the drain hole 15, improving the efficiency of water treatment and enhancing the stability and reliability of the electric hot pot's operation.

[0070] Furthermore, the sunken area 17 is provided with multiple drainage holes 15 at intervals along its circumference to increase the efficiency of water drainage. Even further, the drainage holes 15 are positioned in the sunken area 17 to avoid the adjustable thermostat 10; that is, the horizontal projection of the drainage holes 15 avoids the horizontal projection of the adjustable thermostat 10. It is even possible to maximize the distance between the horizontal projection of the drainage holes 15 and the horizontal projection of the adjustable thermostat 10 within the limits of available space, to prevent drainage from dripping onto the adjustable thermostat 10 and affecting its operation.

[0071] As a preferred embodiment of this application, such as Figure 4 As shown, a second heat insulation gap exists between the water-blocking flange 12 and the heat insulation edge 3. By setting a second heat insulation gap between the water-blocking flange 12 and the heat insulation edge 3, the heat transfer from the water-blocking flange 12 to the heat insulation edge 3 can be reduced, thereby reducing the heat transfer from the heat insulation edge 3 to the outer shell 2, reducing the temperature rise of the outer shell 2, which not only prevents the outer shell 2 from becoming too hot to touch, but also extends the service life of the outer shell 2.

[0072] In this application, the fixing method between the reflector 1 and the outer shell 2 can be any of the following embodiments:

[0073] Implementation Method 3: For example Figure 3 and Figure 5 As shown, a heat insulation component 6 is provided between the outer shell 2 and the reflector 1. The heat insulation component 6 is snapped and fixed to the outer flange 11. The outer shell 2 is provided with a first positioning post 21 located in the heat insulation space 4 and extending downward. The first positioning post 21 is provided with a first positioning hole 22. The heat insulation component 6 is provided with a second positioning hole 64. The reflector 1 and the outer shell 2 are connected by fasteners passing through the second positioning hole 64 and the first positioning hole 22.

[0074] In this third embodiment, by providing a heat insulation component 6 between the outer shell 2 and the reflector 1, contact heat transfer between the reflector 1 and the outer shell 2 can be avoided, reducing the temperature rise of the outer shell 2. The heat insulation component 6 is fixed to the outer flange 11 by snapping, which facilitates the installation and disassembly of the two. The heat insulation component 6 can be assembled onto the reflector 1 without additional tools or complicated operations, greatly improving the assembly efficiency. Furthermore, the heat insulation component 6 is connected to the outer shell 2 by fasteners. Therefore, the setting of the heat insulation component 6 not only reduces the heat transfer from the reflector 1 to the outer shell 2, but also provides a medium for the connection between the reflector 1 and the outer shell 2. The reflector 1 and the outer shell 2 are connected by fasteners passing through the heat insulation component 6, so that the reflector 1, the heat insulation component 6, and the outer shell 2 can be assembled as a module with the other components of the electric hot pot, thereby helping to improve assembly efficiency. Furthermore, compared to placing the first positioning post 21 at the bottom, placing the first positioning post 21 at the top in this third embodiment can shorten the length of the first positioning post 21, thereby saving materials and reducing costs. It also facilitates the connection and fixation between the reflector 1 and the outer shell 2 in the integrated molding of the outer shell 2 and the heat insulation edge 3. In other words, although this third embodiment does not limit the connection and fixation method between the outer shell 2 and the heat insulation edge 3—they can be molded separately and then assembled, or they can be molded as a single piece—the integrated molding method in this third embodiment is more conducive to more conveniently achieving the assembly and positioning of the reflector 1, the heat insulation component 6, and the outer shell 2.

[0075] In a specific implementation, such as Figure 5 and Figure 6 As shown, the outer flange 11 is provided with a positioning notch 13 corresponding to the position of the first positioning post 21. The heat insulation member 6 includes a heat insulation part 61 located above the outer flange 11 and a stop part 62 connected to the heat insulation part 61 and located below the outer flange 11. A slot 63 with an opening facing the positioning notch 13 is formed between the heat insulation part 61 and the stop part 62. The heat insulation member 6 is inserted into the position of the positioning notch 13 through the slot 63. The second positioning hole 64 passes through the heat insulation part 61 and the stop part 62. The heat insulation member 6 passes through the second positioning hole 64 and the first positioning hole 22 from bottom to top to fasten the reflector 1, the heat insulation member 6 and the outer shell 2 together.

[0076] In this embodiment, the distribution of the heat insulation element 6 on the outer flange 11 can be any of the following embodiments:

[0077] Example 1: There are multiple heat insulation elements 6, which are non-uniformly distributed along the outer flange 11. In a specific example, such as... Figure 6 As shown, the outer flange 11 is provided with positioning notches 13 that correspond one-to-one with the heat insulation component 6.

[0078] Example 2: There are multiple heat insulation components 6, which are distributed at equal angles along the outward flange 11. The structure of one heat insulation component differs from the structures of the others. For example, one heat insulation component is made larger to distinguish it from the others. In a specific example, such as... Figure 8 As shown, the outer flange 11 is provided with positioning notches 13 that correspond one-to-one with the heat insulation component 6.

[0079] Both Embodiment 1 and Embodiment 2 enable multiple heat insulation components 6 to have specific installation positions in the circumferential direction of the outer flange 11, thereby providing clear guidance for the assembly of the reflector 1 and the outer shell 2. This ensures that the reflector 1 and the outer shell 2 are assembled with a specific alignment relationship, thereby ensuring the alignment relationship between the water-blocking flange 12 and the internal components of the outer shell 2, so that the water-blocking flange 12 can achieve a better water-blocking effect.

[0080] As a preferred embodiment of this third implementation method, such as Figure 3 As shown, the outer pot also includes a base 9 located below the outer shell 2. The base 9 has an upwardly extending second positioning post 91, and the second positioning post 91 has a third positioning hole. The reflector 1 has a fourth positioning hole 14. The reflector 1 and the base 9 are connected by fasteners passing through the third positioning hole and the fourth positioning hole 14. In this embodiment, the design of the second positioning post 91 on the base 9 and the third positioning hole on the reflector 1 can increase the distance between the base 9 and the reflector 1, thereby forming a heat dissipation space between the base 9 and the reflector 1 and reducing the heat transfer from the reflector 1 to the base 9. The reflector 1 and the base 9 are connected by fasteners, thereby assembling the module composed of the reflector 1, the heat insulation component 6 and the outer shell 2 together with the base 9, which greatly improves the assembly efficiency of the outer pot. Moreover, the connection of the fasteners can ensure that the connection between the reflector 1 and the base 9 is firm, reducing the hidden dangers caused by loose parts and improving the reliability and stability of the electric pot operation.

[0081] Implementation Method 4: This implementation method 4 is not illustrated. In this implementation method 4, a heat insulation component is provided between the outer shell and the reflector. The heat insulation component is snapped and fixed to the outer flange. The outer shell is provided with a first positioning post extending from bottom to top. The first positioning post is provided with a first positioning hole. The heat insulation component is provided with a second positioning hole. The reflector and the outer shell are connected by fasteners passing through the second positioning hole and the first positioning hole.
