Description

Technical Field

[0001] This invention relates to an electric heating pot and an electric heating device. Background Technology

[0002] Electric cookware is a common kitchen appliance in our lives, including rice cookers, induction cookers, and electric frying pans. During daily use, we often find that the food being cooked only occupies a portion of the pan's volume, sometimes only half, or even less. Therefore, a lot of energy is wasted during the electric heating process as the pan itself heats up, while the upper part of the pan is used less frequently. Additionally, the larger size of the pan results in a slower temperature rise.

[0003] To solve these problems, methods such as increasing power or improving the material and thickness of the pot are usually used to improve the temperature rise and efficiency of the pot. However, these methods have limited effect on improving thermal efficiency and will waste additional resources and energy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of low energy utilization rate of electric heating pots in the prior art, and to provide an electric heating pot and electric heating equipment.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] An electric heating pot, characterized in that the electric heating pot includes a pot body and a heating part, the receiving cavity of the pot body is used to receive the object to be heated, and the pot body includes at least two pot sections, which are connected sequentially along the vertical direction.

[0008] In this solution, the electric heating pot has multiple pot sections, and heating elements are provided on at least the side walls of the pot body. This allows each pot section in the pot body to be heated by its corresponding heating element, and the heating element of the corresponding pot section can be activated as needed. This enables the pot body to heat according to the condition of the object to be heated in the pot body's cavity, avoiding energy waste in heating the pot body itself, and improving energy utilization and the efficiency of temperature rise within the pot body.

[0009] Preferably, the pot section includes a bottom pot section and an upper pot section, and the heating part includes a vertical heating part and a horizontal heating part. The vertical heating part is disposed on the outer surface of the side wall of the upper pot section, and the horizontal heating part is disposed on the outer surface of the bottom wall of the bottom pot section.

[0010] In this solution, the heating part can include a vertical heating part and a horizontal heating part. The horizontal heating part refers to the heating part that is arranged on the outer surface of the pot body along the horizontal direction. It is usually arranged at the bottom of the pot body to heat the bottom section of the pot. The vertical heating part refers to the heating part that is arranged on the outer surface of the side wall of the pot body along the vertical direction.

[0011] Preferably, the heating part includes a heating film that covers the outer surface of the corresponding pot section;

[0013] In this design, the heating element can be a heating film covering the outer surface of the pot section, or a heating tube connected to the outer surface of the pot section.

[0014] Preferably, the heating element is fixed to the outer surface of the corresponding pot section by welding or by thermally conductive adhesive.

[0015] Preferably, the pot body further includes a sealing portion connected between two adjacent pot sections, so that the at least two pot sections form a receiving cavity of the pot body.

[0016] In this solution, by setting a sealing part between two adjacent pot sections, multiple pot sections can be connected in sequence to form a receiving cavity, which can accommodate and heat the object to be heated; in addition, the sealing part can also prevent heat conduction between two adjacent pot sections, which can further improve the energy utilization rate.

[0017] Preferably, the sealing part includes an annular body, which is disposed at the connection between two adjacent pot sections, and the surface of the annular body abuts against the connection surface of the pot section.

[0018] Preferably, the abutting surface of the annular body is provided with an abutting portion, the abutting portion including a protruding strip protruding from the abutting surface and a groove recessed into the abutting surface, and the groove is provided on at least one side of the protruding strip.

[0019] In this solution, by setting an abutment part on the abutment surface of the annular body, when two adjacent pot sections are connected to each other, the protrusion of the abutment part is squeezed and deformed, thereby improving the sealing performance; when the protrusion is squeezed, the groove can provide space for the deformation of the protrusion, making the connection between the pot sections tighter.

[0020] Preferably, the sealing portion further includes an extension portion that bends and extends from the outside of the annular body, and the inner surface of the extension portion is in contact with the outer surface of the pot section.

[0021] In this solution, the sealing part also includes an extension part, which can fit against the outer surface of the pot section, thereby further improving the sealing performance and making the connection between the pot sections tighter.

[0022] Preferably, the electric heating pot further includes a sensor disposed between two adjacent pot sections, the sensor being used to detect the liquid level of the substance to be heated within the receiving cavity of the pot body.

[0023] In this solution, the sensor can detect the liquid level of the material to be heated inside the pot body, thereby enabling the corresponding heating element to be activated and the corresponding pot section to be heated based on the liquid level.

[0024] Preferably, the pot body further includes a sealing part, and the detection end of the sensor passes through the sealing part so that the detection end of the sensor communicates with the receiving cavity of the pot body.

[0025] In this solution, the sensor can be connected to the inside of the pot body through the sealing part. When the liquid level of the material to be heated in the pot reaches the position of the sensor, the sensor can detect the height of the liquid level. Furthermore, installing the sensor through the sealing part can make the installation of the sensor more reliable and tight, and prevent the material to be heated from leaking from the sensor installation point.

[0026] Preferably, the electric heating pot further includes a support frame surrounding the outside of the pot body and spaced apart from the pot body to form a heat insulation cavity.

[0027] In this solution, a heat insulation cavity can be formed between the support and the pot body, thereby reducing the diffusion of heat into the surrounding space and also reducing the surface temperature of the electric heating pot that the user can touch.

[0028] Preferably, the electric heating pot further includes a connector located between the pot body and the support, the connector including a first fixing part and a second fixing part connected to the first fixing part, the first fixing part being fixedly connected to the outer side walls of two adjacent pot sections respectively; the second fixing part being used to be fixedly connected to the support.

[0029] In this design, adjacent pot sections and supports can be connected using connectors, resulting in a compact structure.

[0030] Preferably, the electric heating pot further includes a handle, one end of which is connected to the bracket and has an opening; the wire of the heating element extends into the handle through the opening to connect to an external power source.

[0031] In this design, the handle allows the user to hold it for easy use; moreover, the handle also serves as a housing for electrical components, resulting in a compact structure and facilitating connection to an external power source.

[0032] An electric heating device, characterized in that the electric heating device includes an electric heating pot as described above.

[0033] In this solution, the electric heating device uses the aforementioned electric heating pot, whose pot body has multiple pot sections, and heating elements are provided on at least the side walls of the pot body. This allows each pot section in the pot body to be heated by its corresponding heating element, and the heating element of the corresponding pot section can be activated as needed. This enables the pot body to be heated according to the condition of the object to be heated in the pot body's cavity, avoiding energy waste in heating the pot body itself, and improving energy utilization and the efficiency of temperature rise within the pot body.

[0034] Preferably, the electric heating device further includes a chassis, in which a power supply module is provided; the electric heating pot includes a handle, and the wire of the heating element extends into the handle through the opening;

[0035] When the electric heating pot is placed on the chassis, the handle is connected to the chassis so that the heating element is electrically connected to the power supply module of the chassis.

[0036] In this solution, the electric heating device may also include a chassis, and a power supply module may be installed in the chassis, thereby separating the power supply from the electric heating pot, improving the safety performance of electrical components during use; it can also simplify the structure of the electric heating pot itself, making it easier for users to use the electric heating pot.

[0037] Preferably, the heating section includes a horizontal heating section, which is disposed on the outer surface of the bottom wall of the pot section;

[0038] The upper surface of the chassis is provided with a receiving groove for accommodating the horizontal heating element.

[0039] In this design, the horizontal heating element can be installed inside the electric heating pot, and the groove on the base can be used to accommodate the horizontal heating element, thereby limiting the position of the electric heating pot relative to the base during use and preventing the electric heating pot from shaking.

[0040] Preferably, the chassis is further provided with a heating module, the position of which corresponds to the bottom wall of the pot section, and the heating module is used to heat the bottom wall of the pot section.

[0041] In this solution, a heating module can also be installed in the chassis to heat the bottom pot section, thereby simplifying the bottom structure of the electric heating pot and reducing costs.

[0042] The positive and progressive effects of this invention are as follows: the electric heating pot has multiple pot sections in its main body, and heating elements are provided on at least the side walls of the main body, so that each pot section in the main body can be heated by the corresponding heating element. Furthermore, the heating elements of the corresponding pot sections can be turned on as needed, so that the main body can be heated according to the condition of the object to be heated in the pot body cavity, avoiding energy waste in the heating of the main body itself, and improving the energy utilization rate and the efficiency of temperature rise in the main body.

[0093] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0094] This invention provides an electric heating pot 10, which can convert electrical energy into heat energy to heat the object to be heated. The heating methods of the electric heating pot 10 include, but are not limited to, steaming, stir-frying, and deep-frying.

[0095] The electric heating pot 10 includes a pot body 100 and a heating element. The receiving cavity 710 of the pot body 100 is used to receive the object to be heated, which can be a solid, a liquid, or a solid-liquid mixture. Figure 1-4 As shown, the pot body 100 includes at least two pot sections 110, which are connected sequentially along the vertical direction; the heating part is provided on the outer surface of the side wall of the pot body 100 and corresponds to the corresponding pot section 110 to heat the corresponding pot section 110.

[0096] The electric heating pot 10 has a pot body 100 with multiple pot sections 110, and heating elements are provided on at least the side wall of the pot body 100. This allows each pot section 110 in the pot body 100 to be heated by its corresponding heating element. The heating elements of the corresponding pot section 110 can be turned on as needed, so that the pot body 100 can be heated according to the condition of the object to be heated in the pot body 100 cavity 710. This avoids wasting energy on heating the pot body 100 itself, and improves the energy utilization rate and the efficiency of temperature rise in the pot body 100.

[0097] In practical implementation, a heating element is provided on at least the side wall of the pot body 100, so that the heating element can heat the corresponding pot section 110. A corresponding heating element can also be provided on the bottom of the pot body 100, or it can be heated by other devices, such as heating the bottom of the pot body 100 by the chassis 20.

[0098] As a preferred implementation method, such as Figure 2As shown, the pot section 110 includes a bottom pot section 111 and an upper pot section 112. The bottom pot section 111 is located at the bottom of the pot body 100, which is the bottom part of the pot. The upper pot section 112 is located above the bottom pot section 111, which is the side wall part of the pot. Depending on the actual usage requirements, there can be only one upper pot section 112 or multiple upper pot sections 112. When there are multiple upper pot sections 112, the multiple upper pot sections 112 are connected sequentially along the vertical direction and form the receiving cavity 710 of the pot body 100 with the bottom pot section 111.

[0099] Accordingly, the heating section includes a vertical heating section 211 and a horizontal heating section 212. The vertical heating section 211 is disposed on the outer surface of the side wall of the upper pot section 112; the horizontal heating section 212 is disposed on the outer surface of the bottom wall of the bottom pot section 111. In other embodiments, the horizontal heating section 212 may also be disposed in other devices and heat the bottom portion of the pot.

[0100] In a preferred embodiment, the heating element includes a heating film 220 that covers the outer surface of the corresponding pot section 110; and / or, the heating element includes a heating tube 230 that is connected to the outer surface of the corresponding pot section 110.

[0101] In practical implementation, the heating element in the electric heating pot 10 can be entirely a heating film 220, entirely a heating tube 230, or a combination of both. For example, Figure 2 As shown, the heating element in the electric heating pot 10 is a heating film 220. For example... Figure 4 As shown, the vertical heating part 211 in the electric heating pot 10 is a heating tube 230, and the horizontal heating part 212 in the electric heating pot 10 can be a heating tube 230 (not shown in the figure) or a heating film 220 (not shown in the figure).

[0102] In practice, the heating element is fixed to the outer surface of the corresponding pot section 110 by welding or by using thermally conductive adhesive.

[0103] As a preferred implementation method, such as Figure 2-4 As shown, the pot body 100 also includes a sealing portion 120, which is connected between two adjacent pot sections 110 so that at least two pot sections 110 form a receiving cavity 710 of the pot body 100. By providing a sealing portion 120 between two adjacent pot sections 110, multiple pot sections 110 can be connected in sequence to form a receiving cavity 710, thereby accommodating and heating the object to be heated; furthermore, the sealing portion 120 can also be made of a material with poor thermal conductivity to avoid heat conduction between two adjacent pot sections 110, so that the heat from the heating element is concentrated on the corresponding pot section 110.

[0104] like Figure 2-4 As shown, the pot body 100 has two separate pot sections 110. A sealing part 120 can be provided between the two separate pot sections 110, thereby forming a sealed whole with multiple separate pot sections 110. When a food to be heated is placed in the pot, the food will not leak. In addition, the sealing part 120 also serves as a heat insulation, preventing heat conduction between the two pot sections 110.

[0105] In specific implementation, the sealing part 120 can have a corresponding structural form according to the sealing connection requirements between the pot sections 110 and the usage requirements of the inner wall of the pot body 100.

[0106] As a preferred implementation method, such as Figure 2-4 and Figure 5 As shown, the sealing part 120 includes an annular body 121, which is disposed at the connection of two adjacent pot sections 110, and the surface of the annular body 121 abuts against the connection surface of the pot section 110.

[0107] In practice, the pot sections 110 are connected sequentially along the vertical direction, and the annular body 121 is disposed between the lower end face of the upper pot section 110 and the upper end face of the lower pot section 110, and fits against the two end faces respectively, so that the connection between the two pot sections 110 can be sealed.

[0108] As a preferred implementation method, such as Figure 6 As shown, the abutting surface of the annular body 121 is provided with an abutting portion 122. The abutting portion 122 includes a protruding rib 1221 protruding from the abutting surface and a recessed groove 1222 recessed into the abutting surface. At least one side of the protruding rib 1221 is provided with a groove 1222. When two adjacent pot sections 110 are connected to each other, the protruding rib 1221 of the abutting portion 122 is squeezed and deformed, thereby improving the sealing performance. When the protruding rib 1221 is squeezed, the groove 1222 can provide a space to accommodate the deformation of the protruding rib 1221, making the connection between the pot sections 110 more compact.

[0109] like Figure 6 As shown, the abutting part 122 is arranged around the abutting surface of the annular body 121, and grooves 1222 are provided on both sides of the protrusion 1221.

[0110] As a preferred implementation method, such as Figure 6 As shown, the sealing portion 120 also includes an extension portion 123, which bends and extends from the outside of the annular body 121, and the inner surface of the extension portion 123 is in contact with the outer surface of the pot section 110. This can further improve the sealing performance and make the connection between the pot sections 110 more compact.

[0111] like Figure 6As shown, the extension 123 and the annular body 121 can form an L-shaped structure. The upper and lower surfaces of the annular body 121 abut and fit against the surfaces of the upper and lower pot sections 110, respectively, while the inner surface of the extension 123 fits against the outer wall of the upper pot section 110. In a specific implementation, the extension 123 and the annular body 121 can be integrally formed.

[0112] As a preferred implementation method, such as Figure 1 and Figure 2 As shown, the electric heating pot 10 also includes a sensor 300, which is disposed between two adjacent pot sections 110. The sensor 300 is used to detect the liquid level of the substance to be heated in the receiving cavity 710 of the pot body 100.

[0113] In practical implementation, sensor 300 can be a water immersion sensor 300. For example... Figure 1 and Figure 2 As shown, a sensor 300 is placed between two adjacent heating films 220. The sensor 300 can detect the liquid level inside the pot body 100, and thus activate the corresponding heating film 220 for heating based on the liquid level, thereby saving energy and avoiding waste. Specifically, when two adjacent sensors 300 are immersed in the object to be heated, it indicates that there is an object to be heated in the pot body 100 below the sensor 300, requiring heating. In this case, all heating films 220 below the sensor 300 can be activated for heating. Furthermore, multiple sensors 300 can be placed circumferentially between two adjacent pot sections 110. Multiple sensors 300 can detect multiple liquid levels in the circumferential direction of the object to be heated, avoiding detection errors caused by unbalanced placement of the pot body 100 or the state of the object to be heated inside the pot. Specifically, if the operating plane of the pot body 100 is flat, or if the object to be heated inside the pot body 100 contains a lot of solids, or if the liquid level of the object to be heated is not horizontal, the detection result may be inaccurate if only one sensor 300 is used. By setting multiple sensors 300, the liquid level at different positions can be detected at the same height of the pot body 100. The data from multiple liquid levels is processed, and the final liquid level result is output to control the start of the heating film 220.

[0114] As a preferred implementation method, such as Figure 2As shown, the pot body 100 also includes a sealing part 120. The detection end of the sensor 300 passes through the sealing part 120 so that the detection end of the sensor 300 communicates with the receiving cavity 710 of the pot body 100. The sensor 300 can communicate with the inside of the pot body 100 through the sealing part 120. When the liquid level of the material to be heated in the pot reaches the position of the sensor 300, the sensor 300 can detect the height of the liquid level. Furthermore, installing the sensor 300 through the sealing part 120 makes the installation of the sensor 300 more reliable and tight, preventing the material to be heated from leaking from the installation point of the sensor 300.

[0115] As a preferred implementation method, such as Figure 2-4 As shown, the electric heating pot 10 also includes a support 400, which surrounds the outside of the pot body 100 and is spaced apart from the pot body 100 to form a heat insulation cavity. This reduces heat diffusion into the surrounding space and also lowers the surface temperature of the electric heating pot 10 that the user can touch.

[0116] like Figure 7 As shown, the support 400 includes a support body 410 and a first connecting portion 420. The support body 410 surrounds the outer wall of the pot body 100, and one end of the support body 410 is connected to the pot body 100. The first connecting portion 420 is connected to the other end of the support body 410 and extends toward the interior of the support body 410. The first connecting portion 420 is used to fixably connect to the pot body 100 and form a heat insulation cavity with the pot body 100. By setting the support 400 on the outside of the pot body 100, and by having the support body 410 surround the outside of the pot body 100, and by having a gap between the support body 410 and the pot body 100 through the first connecting portion 420 to form a heat insulation cavity, heat loss from the pot can be reduced, and burns can be avoided when the user accidentally touches the pot.

[0117] like Figure 7 As shown, the top pot section 110 can extend away from the receiving cavity 710 to form a second connecting portion 1121, forming a generally L-shaped structure. When the bracket 400 is installed on the outside of the top pot section 110, the bracket body 410 can wrap around the outer wall of the pot body 100 in a vertical direction, and the first connecting portion 420 extends horizontally towards the pot body 100 and is fixedly connected to the outer wall of the pot body 100. The bracket body 410 and the first connecting portion 420 can form a generally L-shaped structure. The bracket 400 can be made of a material with poor thermal conductivity; for example, the bracket 400 can be a plastic part. Figure 2As shown, multiple supports 400 can be sequentially arranged below the support 400. The support body 410 of the lower support 400 contacts the support body 410 of the upper support 400, and the first connecting part 420 of the lower support 400 is fixedly connected to the side wall of the pot body 100.

[0118] like Figure 9 and Figure 10 As shown, the support 400 also includes a spacer 430, which is connected to the first connecting portion 420 and is spaced apart from the support body 410. The height of the spacer 430 is lower than the height of the support body 410. The spacer 430 increases the structural strength of the support 400. Furthermore, since the spacer is located between the support body 410 and the pot body 100, when heat from the pot body 100 dissipates into the surrounding environment, some of the heat can first pass through the space between the spacer 430 and the pot body 100, and then through the space between the spacer 430 and the support body 410, thereby improving the heat insulation effect.

[0119] like Figure 10 As shown, one end of the spacer portion 430 is connected to the upper surface of the first connecting portion 420 and extends away from the first connecting portion 420. In one specific embodiment, the bracket body 410 can extend vertically, the first connecting portion 420 can extend horizontally, and the partition portion is located inside the bracket body 410 and extends vertically. The spacer portion 430 is also generally annular, and the spacer portion 430 and the bracket body 410 can be coaxially arranged. A notch is provided at a certain position in the spacer portion 430, which can reserve space for the fastener to fix the bracket 400.

[0120] like Figure 9 As shown, a first reinforcing member 440 is provided between the surface of the spacer portion 430 facing the interior of the bracket body 410 and the first connecting portion 420. The first reinforcing member 440 protrudes from the surface of the spacer portion 430 toward the interior of the bracket body 410.

[0121] like Figure 9 As shown, the surface of the spacer 430 facing the inside of the support body 410 is the inner wall of the spacer 430. Multiple first reinforcing members 440 may be provided between the inner wall of the spacer 430 and the first connecting part 420. The multiple first reinforcing members 440 are arranged around the inner wall of the spacer 430.

[0122] like Figure 9 As shown, a second reinforcing member 450 is provided between the spacer portion 430, the support body 410, and the first connecting portion 420. The second reinforcing member 450 can further improve the structural strength of the support 400.

[0123] like Figure 7As shown, the spacer 430 is located outside the extension 123, and the first reinforcing member 440 is located above the extension 123. It can provide a certain limiting effect on the seal, preventing deformation of the seal and thus ensuring proper sealing. Correspondingly, as... Figure 4 As shown, when the heating part is a heating tube 230, the spacer 430 and the second reinforcing member 450 can also play a certain limiting role for the heating tube 230.

[0124] The aforementioned bracket 400 can be disposed on the outer side wall of the pot body 100 and correspond to the heating film 220 disposed on the outer side wall, so that the heating film 220 can be accommodated in the heat insulation cavity.

[0125] like Figure 2 As shown, for an electric heating pot 10 with a horizontal heating section 212 at the bottom, the electric heating pot 10 also includes a bottom support 510 and a bottom shell 520. The bottom support 510 is connected to the bottom of the pot body 100, and the bottom shell 520 is connected to the bottom support 510 to form a receiving portion. The horizontal heating section 212 can be located in the receiving portion to protect the horizontal heating section 212 from wear.

[0126] As a preferred implementation method, such as Figure 8 As shown, the electric heating pot 10 also includes a connector 600 located between the pot body 100 and the support 400. The connector 600 includes a first fixing part 610 and a second fixing part 620 connected to the first fixing part 610. The first fixing part 610 is fixedly connected to the outer side wall of two adjacent pot sections 110 respectively; the second fixing part 620 is used to fixally connect to the support 400.

[0127] like Figure 8 As shown, the first fixing part 610 and the second fixing part 620 form a roughly L-shaped structure. The first fixing part 610 can be welded to two adjacent pot sections 110 respectively to improve the reliability and stability of the connection. The second fixing part 620 and the first connecting part 420 of the bracket 400 can be fixed by fasteners. The first connecting part 420 and the second fixing part 620 are respectively provided with through holes, and fasteners can pass through the through holes from bottom to top to fix the connector 600 to the bracket 400. This makes the assembly process more convenient.

[0128] As a preferred implementation method, such as Figure 2 As shown, the electric heating pot 10 also includes a handle 700, one end of which is connected to the bracket 400 and has an opening; the heating element’s wire extends into the handle 700 through the opening to connect to an external power source.

[0129] like Figure 2As shown, the wires of the heating element and the sensor 300 can both extend into the handle 700 through the opening. The handle 700 includes a receiving cavity 710 near the opening and a hand-held portion 720 away from the opening. A control module 800 can be housed in the receiving cavity 710, and the wires can be connected to the control module 800 after extending into the receiving cavity 710 through the opening. Specifically, as... Figure 2 As shown, the receiving cavity 710 has an inclined mounting plate 711. The outer surface of the mounting plate 711 has a connector 730. The electrical connection terminal of the control module 800 can be disposed in the connector 730 so that after the connector 730 is plugged into the corresponding device, the control module 800 can be electrically connected to the electrical connection terminal in the corresponding device.

[0130] This invention also provides an electric heating device 1, such as... Figure 1 and Figure 2 As shown, the electric heating device 1 includes the electric heating pot 10 as described above.

[0131] The electric heating device 1 employs the aforementioned electric heating pot 10, whose pot body 100 has multiple pot sections 110, and heating elements are provided on at least the side walls of the pot body 100. This allows each pot section 110 in the pot body 100 to be heated by its corresponding heating element, and the heating element of the corresponding pot section 110 can be activated as needed. This enables the pot body 100 to be heated according to the condition of the object to be heated in the pot body 100 cavity 710, avoiding energy waste in the heating of the pot body 100 itself, and improving energy utilization and the efficiency of temperature rise within the pot body 100.

[0132] As a preferred implementation method, such as Figure 2 As shown, the electric heating device 1 also includes a chassis 20, within which a power supply module 23 is housed; the electric heating pot 10 includes a handle 700, with the heating element's wires extending into the handle 700 through an opening; when the electric heating pot 10 is mounted on the chassis 20, the handle 700 is connected to the chassis 20, thereby electrically connecting the heating element to the power supply module 23 of the chassis 20. This separates the power supply from the electric heating pot 10, improving the safety performance of electrical components during use; it also simplifies the structure of the electric heating pot 10 itself, making it easier for users to operate.

[0133] like Figure 2 As shown, the power supply module 23 can be housed within the chassis 20. The electric heating pot 10 is plugged into the chassis 20, allowing the electrical components within the electric heating pot 10 to be electrically connected to the power supply module 23, thus supplying power to the electric heating pot 10. In practical implementation, other components can also be housed within the chassis 20, thereby simplifying the components of the electric heating pot 10, resulting in a compact structure and ease of use.

[0134] like Figure 2 As shown, the chassis 20 includes a chassis body 21 and a protrusion 22. The chassis body 21 has a generally flat structure, and the pot body 100 of the electric heating pot 10 can be mounted on the chassis body 21. A protrusion 22 is provided at one end of the chassis body 21. The upper surface of the protrusion 22 can have a connector that matches the plug-in 730 of the handle 700, so that when the electric heating pot 10 is placed on the chassis body 21, the plug-in 730 of the handle 700 can be aligned with and plugged into the connector of the protrusion 22 to form an electrical connection. The connector can be a waterproof connector.

[0135] In a preferred embodiment, the heating element includes a horizontal heating element 212, which is disposed on the outer surface of the bottom wall of the pot section 110; the upper surface of the base 20 is provided with a receiving groove for accommodating the horizontal heating element 212. This restricts the position of the electric heating pot 10 relative to the base 20 during use and also prevents the electric heating pot 10 from shaking.

[0136] like Figure 2 As shown, both the bottom support 510 and the bottom shell 520 can be accommodated in the receiving groove, so that the bottom surface of the pot body 100 can fit against the upper surface of the chassis body 21, and the chassis body 21 can bear the weight of the electric heating pot 10.

[0137] As another preferred embodiment, a heating module is also provided in the chassis 20. The position of the heating module corresponds to the bottom wall of the pot section 110. The heating module is used to heat the bottom wall of the pot section 110.

[0138] In a specific implementation, the horizontal heating part 212 can also be installed in other components besides the electric heating pot 10, such as inside the chassis body 21. The position of the horizontal heating part 212 inside the chassis body 21 is opposite to the position of the electric heating pot 10 when it is installed on the chassis body 21, so that the horizontal heating part 212 can heat the bottom pot section 111.

[0139] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
