Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a cooking pot body and an electric hot pot containing the same. Background Technology

[0002] To achieve the desired instant cooking effect, the pot is usually divided into two chambers of different sizes, each with its own independent heating structure. This allows for separate control of the heating effect in each chamber, especially by utilizing the high-power heating of the smaller chamber.

[0003] In related technologies, heating structures mostly include a heating plate and a heating element. The heating plate area in a small cavity is relatively small, resulting in a high heat load per unit area and consequently, an excessively high heating plate temperature. Prolonged use can easily lead to heating element deformation or bursting. Conversely, if the heating plate temperature in the small cavity is kept too low, the quick-wash function will be affected. Utility Model Content

[0004] Therefore, it is necessary to provide a cooking pot body that, while reducing the time users have to wait for cooking due to the small cavity and rapid boiling, improves the protection of the heating element and reduces the risk of heating element deformation and bursting.

[0005] A cooking pot body includes a pot body with a pot cavity, a baffle plate, and a heating assembly; the baffle plate is disposed in the pot cavity and divides the pot cavity into a first cavity and a second cavity, the volume of the first cavity being smaller than the volume of the second cavity; the heating assembly includes a first heating tube and a second heating tube spaced apart at the bottom of the pot body, both the first heating tube and the second heating tube having an effective heating section, the effective heating section of the first heating tube being located within the projection of the first cavity along the vertical direction; wherein, a first ratio k1 of the heating power of the first heating tube to the volume of the first cavity satisfies: 750W / L≤k1≤1100W / L.

[0006] Understandably, once the position of the baffle relative to the pot body is determined, the volume of the first cavity is fixed. To ensure the first cavity quickly absorbs heat from the first heating element while preventing damage to it, the heating power of the first heating element needs to be limited to meet a first ratio k1. When the first ratio k1 is greater than or equal to 750 W / L, it avoids insufficient heating power due to a small ratio, which could affect the rapid boiling of the liquid in the first cavity. When the first ratio k1 is less than or equal to 1100 W / L, it avoids deformation and bursting of the first heating element 131 due to an excessively large ratio. This allows the liquid in the first cavity to absorb the heat generated by the first heating element promptly and effectively, thus mitigating the problem of a rapid increase in surface temperature caused by the inability to dissipate heat effectively and promptly. This improves the protection of the heating element and reduces the risk of deformation and bursting.

[0007] In some embodiments, the second ratio k2 of the volume of the first cavity and the volume of the second cavity satisfies:

[0008] .

[0009] This setting, by limiting the range of the second ratio k2, effectively limits the volume range of the first cavity, thereby reducing the risk of deformation and bursting of the first heating element while ensuring rapid boiling.

[0010] In some embodiments, the third ratio k3 between the heating power of the first heating element and the surface area of ​​the effective heating section in the first heating element satisfies: k3 ≤ 25 W / cm² 2 .

[0011] In other words, by limiting the third ratio, the heating power of the first heating element is further limited, keeping the heating power of the first heating element within a safe range and avoiding the problem of the surface temperature of the first heating element being too high as much as possible.

[0012] In some embodiments, the first heating element is riveted to the pot body, and the third ratio k3 satisfies: 10W / cm² 2 ≤k3≤12W / cm 2 ;

[0013] Alternatively, the first heating element is welded to the pot body, and the third ratio k3 satisfies:

[0014] 18W / cm 2 ≤k3≤22W / cm 2 .

[0015] Understandably, the third ratio needs to be reduced accordingly during riveting to ensure that the first heating element is fully heated while reducing the corrosion impact at the riveting gap and improving safety. During welding, the third ratio can be increased accordingly, that is, the heating power of the first heating element can be increased accordingly. This improves heating efficiency and significantly facilitates rapid boiling while avoiding deformation or bursting of the first heating element.

[0016] In some embodiments, the heating assembly further includes a heat-conducting element disposed at the bottom of the pot body, wherein the first heating tube and the second heating tube are both disposed on the side of the heat-conducting element away from the pot body.

[0017] In other words, by utilizing the heat-conducting components, the heat generated by the first and second heating elements can be fully transferred to their respective cavities to meet the heating requirements.

[0018] In one embodiment, the heat-conducting component is provided with a heat-insulating groove, the projection of the heat-insulating groove in the vertical direction coincides with the projection of the baffle in the vertical direction.

[0019] Understandably, by using the heat insulation groove, the amount of heat diffusion from the first heating element to the second cavity can be reduced, which is conducive to the heat of each heating element being fully transferred to the corresponding cavity.

[0020] In some embodiments, the first cavity has a length direction and a width direction, and the first heating element also has a first coupling terminal connected to the corresponding effective heating section, the first coupling terminal being located on one side of the length direction of the first cavity.

[0021] This configuration ensures that the entire first heating element is located within the vertical projection of the first cavity, reducing assembly interference and heating interference between the first and second heating elements.

[0022] In some embodiments, the first cavity has a length direction and a width direction, and the first heating element also has a first coupling terminal connected to the corresponding effective heating section, the first coupling terminal being located on the side of the first cavity near the second heating element along the width direction.

[0023] This setup is equivalent to adjusting the position of the first coupling terminal to the bottom of the pot body near the center, so as to avoid short circuits caused by the liquid left along the edge of the pot body coming into contact with the coupler that mates with the first coupling terminal.

[0024] In some embodiments, the first coupling terminal protrudes beyond the projection of the first cavity in the vertical direction.

[0025] In this way, a portion of the second cavity can be used for the arrangement of the first coupling terminal, thereby ensuring that the first effective heating section has sufficient length to meet the rapid boiling of the first cavity.

[0026] In some embodiments, the height of the baffle in the vertical direction is not greater than the height of the pot opening of the pot body.

[0027] This design ensures that the baffle does not protrude from the edge of the pot body, reducing interference with the lid's fit and ensuring that the edge of the lid and the edge of the pot body fit as closely as possible, thereby reducing liquid splashing.

[0028] In some embodiments, the height of the baffle is H1 in the vertical direction, and the height of the pot opening of the pot body is H2. Then H1 and H2 satisfy:

[0029] .

[0030] This improves the problem of liquids splashing between the first and second chambers after boiling due to the low baffle, thereby reducing the risk of heat exchange between the liquids in the two chambers and facilitating rapid boiling in the first chamber.

[0031] In some embodiments, the vertical projection of the pot cavity is rectangular, and the baffle is located on one side of the length direction of the pot cavity.

[0032] This configuration ensures that the dimensions of the first cavity and the second cavity are consistent along the width of the pot cavity. The volume of the first cavity can be determined solely by the position of the baffle along the length of the pot cavity, thus maintaining the first cavity at a relatively small volume.

[0033] In some embodiments, the baffle is integrally formed with the pot body.

[0034] This not only facilitates production and manufacturing but also ensures the airtightness of the connection between the two, preventing food or liquid from mixing in the first and second cavities.

[0035] This application also provides an electric hot pot, including a base and the aforementioned cooking pot body, wherein the cooking pot body is supported on the base. Attached Figure Description

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, the pot body is typically divided into two cavities of different sizes, each equipped with an independent heating structure to meet the heating control needs of different cavities, especially utilizing the high-power heating of the smaller cavity to achieve a quick-cooking effect. The heating structure usually includes a heating plate and a heating element. To achieve a more pronounced quick-cooking effect, the heating plate area corresponding to the smaller cavity is also correspondingly smaller, so that it does not protrude as much as possible from the vertical projection of the smaller cavity, ensuring that the heat from the heating plate is fully transferred to the smaller cavity.

[0052] However, when the heating element in the small cavity is heated with high power, the heat generated per unit area of ​​the heating element is significantly higher. Since the corresponding heating plate area is small, the heat load per unit area of ​​the heating plate is high, leading to the problem of excessively high heating plate temperature. If the heating plate remains at a high temperature for a prolonged period, the internal heating element will overheat, affecting the material properties of the heating element and posing a risk of deformation. Furthermore, excessively high temperatures can cause excessive internal pressure in the heating element, potentially leading to element bursting. Conversely, if the heating element is heated with relatively low power, the heating plate temperature will be too low to maintain stable and continuous heating, weakening the quick-rinse effect or even preventing it from being achieved.

[0053] To address this, one embodiment of this application provides a cooking pot body that, while satisfying the requirement of quick rinsing in a small cavity, improves the protection of the heating element and reduces the risk of heating element deformation and bursting. The specific structure of this cooking pot body is described in detail below.

[0054] Please see Figures 1 to 4For example, the cooking pot body 100 includes a pot body 110 with a pot cavity 111 and a baffle plate 120 disposed in the pot cavity 111. The baffle plate 120 divides the pot cavity 111 into a first cavity 1111 and a second cavity 1112, and the volume of the first cavity 1111 is smaller than the volume of the second cavity 1112. The cooking pot body 100 also includes a heating assembly 130 disposed at the bottom of the pot body 110. The heating assembly 130 includes a first heating element 131 and a second heating element 132 spaced apart at the bottom of the pot body 110. Both the first heating element 131 and the second heating element 132 include an effective heating section, that is, the first heating element 131 corresponds to a first effective heating section 1311, and the second heating element 132 corresponds to a second effective heating section 1321. The first effective heating section 1311 is located within the projection of the first cavity 1111 in the vertical direction. The first ratio k1 of the heating power of the first heating tube 131 to the volume of the first cavity 1111 satisfies: 750W / L≤k1≤1100W / L.

[0055] It should be noted in advance that the first heating element 131 and the second heating element 132 also include coupling terminals connected to their respective corresponding effective heating sections. The first heating element 131 corresponds to the first coupling terminal 1312, which is connected to the first effective heating section 1311. The second heating element 132 corresponds to the second coupling terminal 1322, which is connected to the second effective heating section 1321. The two coupling terminals are used to cooperate with a coupler. The first effective heating section 1311 refers to the portion of the first heating element 131 used for directly heating the liquid in the first cavity 1111, and the second effective heating section 1321 refers to the portion of the second heating element 132 used for directly heating the liquid in the second cavity 1112.

[0056] Meanwhile, the first ratio k1 between the heating power of the first heating element 131 and the volume of the first cavity 1111 reflects the heating power transferred from the first heating element 131 to the first cavity 1111 per unit volume, which is the volumetric power density. The larger the first ratio k1, the faster the liquid in the first cavity 1111 heats up; conversely, the smaller the first ratio k1, the slower the liquid in the first cavity 1111 heats up.

[0057] Understandably, both the first cavity 1111 and the second cavity 1112 contain liquid. The first heating element 131 and the second heating element 132 can simultaneously heat the first cavity 1111 and the second cavity 1112 through their respective effective heating sections. Since the first cavity 1111 has a smaller volume, in the initial heating stage, the first heating element 131 can be controlled to heat at a higher power, thereby transferring heat as fully as possible to the first cavity 1111 through the first effective heating section 1311 to achieve rapid boiling and shorten the user's waiting time for cooking. Simultaneously, once the position of the baffle 120 relative to the pot body 110 is determined, the volume of the first cavity 1111 is fixed. To ensure that the first cavity 1111 quickly absorbs heat from the first heating element 131 while preventing damage to the first heating element 131, the heating power of the first heating element 131 needs to be limited to meet the first ratio k1. Specifically, when the first ratio k1 is greater than or equal to 750 W / L, it can prevent the heating power from being too low due to an excessively small first ratio, thus avoiding the rapid boiling of the liquid in the first cavity 1111. When the first ratio k1 is less than or equal to 1100 W / L, it can prevent the deformation and bursting of the first heating element 131 due to an excessively large first ratio. For example, if the volume of the first cavity 1111 is 2L, to achieve the above effect, the heating power of the first heating element 131 can be between 1500W and 2200W. In this way, the liquid in the first cavity 1111 can absorb the heat generated by the first heating element 131 in a timely and effective manner, alleviating the problem of a rapid increase in surface temperature caused by the inability to dissipate the heat generated by the first heating element 131 in a timely and effective manner, thereby improving the protection of the heating element and reducing the risk of deformation and bursting of the heating element.

[0058] In some specific embodiments, the first ratio k1 can be 750W / L, 800W / L, 850W / L, 900W / L, 960W / L, 1100W / L, etc.

[0059] The second heating element 132 is located entirely within the projection of the second cavity 1112.

[0060] Furthermore, the height of the opening of the first cavity 1111 is the same as the height of the baffle 120 in the vertical direction. The cross-sectional area of ​​the first cavity 1111 is S1, and the height of the opening of the first cavity 1111 is H1, which is also the height of the baffle 120 in the vertical direction. Therefore, the expression for the volume V1 of the first cavity 1111 is: V1 = S1 × H1. Taking the heating power of the first heating element 131 as P1, the first ratio k1 satisfies:

[0061] .

[0062] The height of the opening of the first cavity 1111 serves as the maximum liquid level within it. Normally, the liquid level in the first cavity 1111 is less than the height of its opening. Therefore, during operation, the first heating element 131 is continuously heated at a higher power, i.e., P1 remains constant. When the liquid level in the first cavity 1111 is high, the corresponding first ratio k1 is low, resulting in a slower temperature rise and hindering rapid boiling. Conversely, when the liquid level in the first cavity 1111 is low, the corresponding first ratio k1 is high, resulting in a faster temperature rise and facilitating rapid boiling. Therefore, when the first ratio k1 is calculated based on the height of the opening of the first cavity 1111, even reducing the liquid level in the first cavity 1111 can maintain rapid boiling while minimizing the risk of deformation and bursting of the first heating element 131.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the second ratio k2 of the volume of the first cavity 1111 and the volume of the second cavity 1112 satisfies:

[0064] .

[0065] In other words, the volume of the first cavity 1111 is greater than or equal to one-third of the volume of the second cavity 1112, but less than the volume of the second cavity 1112. According to the aforementioned expression for the volume V1 of the first cavity 1111, since the opening height of the first cavity 1111 and the opening height of the second cavity 1112 are the same, the cross-sectional areas of the first cavity 1111 and the second cavity 1112 are used as variables affecting the second ratio k2. Specifically, when the second ratio k2 is greater than or equal to one-third, it can prevent the first heating element 131 from deforming and bursting due to the first cavity 1111 being too small because the second ratio k2 is too small; when the second ratio is less than the volume of the second cavity 1112, it can prevent the first cavity 1111 from becoming too large because the second ratio k2 is too large, thus preventing the rapid boiling of the liquid inside the first cavity 1111 from being weakened. Therefore, by limiting the range of the second ratio k2, the volume range of the first cavity 1111 is effectively limited, so that it can reduce the risk of deformation and bursting of the first heating tube 131 while satisfying rapid boiling.

[0066] Wherein, when the volume of the first cavity 1111 and the volume of the second cavity 1112 satisfy the aforementioned second ratio k2, the fifth ratio k5 between the volume of the first cavity 1111 and the volume of the pot cavity 111 is satisfied:

[0067] .

[0068] In some specific embodiments, when the fifth ratio k5 = 1 / 3, the second ratio k2 = 1 / 2.

[0069] In some other specific embodiments, the second ratio k2 can also be: 1 / 3, 2 / 3, 3 / 4, 4 / 5, etc.

[0070] In some specific embodiments, the vertical projection of the pot cavity 111 is rectangular, and the baffle 120 is disposed along the length of the pot cavity 111 (i.e., Figure 1 The first cavity 1111 and the second cavity 1112 are positioned along the width direction of the pot cavity 111 (i.e., the left and right directions). This arrangement ensures that the first cavity 1111 and the second cavity 1112 are positioned along the width direction of the pot cavity 111 (i.e., the left and right directions). Figure 1 The dimensions (vertical direction) of the pot cavity 111 are kept consistent. The volume of the first cavity 1111 can be determined solely by the position of the baffle 120 along the length of the pot cavity 111, thereby maintaining the first cavity 1111 in a smaller volume. For example, the pot cavity 111 has a first cavity wall and a second cavity wall that are arranged opposite to each other and spaced apart along its own length. The baffle 120 is positioned close to the second cavity wall. The space between the second cavity wall and the baffle 120 serves as the first cavity 1111, and the space between the second cavity wall and the baffle 120 serves as the second cavity 1112.

[0071] Alternatively, the vertical projection of the pot cavity 111 can also be square or circular, as long as it can maintain the small volume of the first cavity 1111 and facilitate timely and effective absorption of the heat from the first heating tube 131.

[0072] Please see Figures 1 to 4 In some embodiments, the third ratio k3 of the heating power of the first heating element 131 to the surface area of ​​the effective heating section in the first heating element 131 satisfies: k3 ≤ 25 W / cm² 2 The third ratio k3 refers to the heating power of the first heating element 131 per unit area, calculated based on the outer surface area of ​​the first effective heating section 1311 on the first heating element 131. If the area power density of the first heating element 131 is k3, and the outer surface area of ​​the first effective heating section 1311 is S2, then the expression for k3 is:

[0073] .

[0074] Since the outer surface area of ​​the first effective heating section 1311 on the first heating element 131 is a constant, the heating power of the first heating element 131 is a variable affecting the third ratio k3. When the third ratio k3 is large, the heating power of the first heating element 131 is large. Conversely, when the third ratio k3 is small, the heating power of the first heating element 131 is small. Therefore, by limiting the third ratio k3, the heating power of the first heating element 131 is further limited, maintaining the heating power of the first heating element 131 within a safe range, minimizing the risk of excessively high surface temperature of the first heating element 131, and thus reducing the risk of deformation and bursting of the first heating element 131.

[0075] Therefore, in this embodiment, based on the aforementioned first ratio k1, the heating power of the first heating element 131 is limited by the volume of the first cavity 1111; and, using the third ratio k3, the heating power of the first heating element 131 is limited by its own dimensions. This forms a dual protection, further ensuring that the heat from the first heating element 131 can be transferred to the first cavity 1111 in a timely and effective manner, satisfying the requirement for rapid boiling.

[0076] Furthermore, the first heating element 131 can be riveted to the pot body 110, at which point the third ratio k3 satisfies:

[0077] 10W / cm 2 ≤k3≤12W / cm 2 .

[0078] Because assembly gaps exist during the riveting of the first heating element 131, interfacial thermal resistance exists; furthermore, external moisture can easily seep in and cause electrochemical corrosion at these gaps. Therefore, a larger third ratio k3 leads to excessively high temperatures at the assembly gaps, resulting in greater corrosion. Thus, during riveting, the third ratio k3 needs to be appropriately reduced, meaning the heating power of the first heating element 131 needs to be reduced accordingly. This not only extends its service life but also improves operational safety.

[0079] In some specific embodiments, when the first heating element 131 is riveted to the pot body 110, the third ratio k3 can be 10 W / cm². 2 10.5W / cm 2 11W / cm 2 11.2W / cm 2 11.8W / cm 2 Or 12W / cm 2 .

[0080] In some other embodiments, the first heating element 131 can be welded to the pot body 110, in which case the third ratio k3 satisfies:

[0081] 18W / cm2 ≤k3≤22W / cm 2 .

[0082] Understandably, when the first heating element 131 is welded relative to the pot body 110, the molten metal fills the gaps or crevices between the first heating element 131 and the pot body 110, thus preventing the penetration of external moisture. Therefore, the third ratio k3 can be increased accordingly, improving heating efficiency while avoiding deformation or bursting of the first heating element 131, which is significantly beneficial for rapid boiling.

[0083] In some specific embodiments, when the first heating element 131 is welded to the pot body 110, the third ratio k3 can be 18 W / cm². 2 19W / cm 2 20W / cm 2 20.5W / cm 2 21W / cm 2 Or 22W / cm 2 .

[0084] Please continue reading. Figures 1 to 4 In some embodiments, the heating assembly 130 further includes a heat-conducting element 133, which is disposed at the bottom of the pot body 110. The first heating element 131 and the second heating element 132 are both disposed on the side of the heat-conducting element 133 away from the pot body 110. That is, by utilizing the heat-conducting element 133, the heat generated by the first heating element 131 and the second heating element 132 can be fully transferred to their respective cavities to meet the heating requirements. Moreover, because the first heating element 131 and the second heating element 132 share the heat-conducting element 133, the heat-conducting element 133 has a large heat transfer area, thereby reducing the heat load on the heat-conducting element 133 when the first heating element 131 heats the first cavity 1111, which is conducive to timely and effective heat transfer.

[0085] The heat-conducting component 133 can be arranged in a plate-like structure that is adapted to the bottom of the pot body 110, and can be made of a material with good thermal conductivity, such as aluminum.

[0086] In some specific embodiments, the pot body 110 is made of die-cast aluminum, and the bottom of the pot body 110 itself has a high thermal conductivity. In this case, the heat-conducting component 133 can be omitted from the bottom of the pot body 110, and the first heating element 131 can be directly riveted or welded to the pot body 110. Alternatively, the pot body 110 can be made of stainless steel, and the heat-conducting component 133 can be welded to the bottom of the pot body 110 first, and then the first heating element 131 can be welded or riveted to the heat-conducting component 133.

[0087] The fourth ratio of the heating power of the second heating tube 132 to the surface area of ​​the effective heating section in the second heating tube 132 is the same as the third ratio mentioned above, and the fixing method of the second heating tube 132 is the same as that of the first heating tube 131, so it will not be described again here.

[0088] like Figure 2 and Figure 3 As shown, in some embodiments, the heat-conducting component 133 is provided with a heat-insulating groove 1331, the projection of the heat-insulating groove 1331 in the vertical direction coincides with the projection of the baffle 120 in the vertical direction. That is, the heat-conducting component 133 is provided with a heat-insulating groove 1331 at the junction of the first cavity 1111 and the second cavity 1112 to reduce heat conduction between the first cavity 1111 and the second cavity 1112. In particular, when the first heating tube 131 needs to be heated with a large power in the initial stage of heating, the temperature in the second cavity 1112 is significantly lower than the temperature in the first cavity 1111. Therefore, the heat-insulating groove 1331 can be used to prevent the heat of the first heating tube 131 from diffusing towards the second cavity 1112, which is conducive to the full transfer of the heat of the first heating tube 131 to the first cavity 1111.

[0089] Alternatively, the first heating element 131 and the second heating element 132 may each be provided with an independent heat-conducting element 133, and a heat-insulating gap may be provided between the two heat-conducting elements 133, as long as it can maintain sufficient heat transfer. This is just an example.

[0090] like Figure 1 and Figure 2 As shown, in some embodiments, the vertical height of the baffle 120 is no greater than the height of the pot opening of the pot body 110. This arrangement ensures that the baffle 120 does not protrude from the edge of the pot opening of the pot body 110, thereby reducing interference with the lid's engagement with the pot body 110 and ensuring that the edge of the lid and the edge of the pot opening of the pot body 110 can be as close as possible, thus reducing liquid splashing. Specifically, the vertical height of the baffle 120 is less than the height of the pot opening of the pot body 110. Alternatively, the vertical height of the baffle 120 is the same as the height of the pot opening of the pot body 110, that is, the top of the baffle 120 is flush with the edge of the pot opening of the pot body 110.

[0091] Furthermore, along the vertical direction, the height of the baffle 120 is H1, and the height of the pot opening of the pot body 110 is H2. Then H1 and H2 satisfy:

[0092] .

[0093] In other words, the height of the baffle 120 is not less than two-thirds of the height of the pot opening of the pot body 110. If the height of the baffle 120 is too low, there may be a problem of heat exchange caused by the liquids in the first cavity 1111 and the second cavity 1112 splashing each other after boiling, reducing the cooking speed in the first cavity 1111. Moreover, since the height of the pot openings of the first cavity 1111 and the second cavity 1112 is based on the height of the baffle 120, if the height of the baffle 120 is too small, the volume of the first cavity 1111 and the second cavity 1112 will be too small, reducing the utilization rate of the pot cavity 111.

[0094] In summary, the height H1 of the baffle 120 needs to meet the following requirements:

[0095] .

[0096] By limiting the height of the baffle 120, the risk of heat exchange between the first cavity 1111 and the second cavity 1112 is reduced, while making full use of the space in the pot cavity 111. This also reduces interference when the pot lid is fastened.

[0097] In some specific embodiments, the height H1 of the baffle 120 can satisfy:

[0098] H1 = 0.7 × H2, or H1 = 0.75 × H2, or H1 = 0.8 × H2, or H1 = 0.85 × H2, or H1 = 0.9 × H2, or H1 = 0.95 × H2, or H1 = H2.

[0099] The baffle plate 120 is integrally formed with the pot body 110, which not only facilitates manufacturing but also ensures the sealing of the connection between the two, preventing food or liquid from mixing in the first cavity 1111 and the second cavity 1112. For example, the baffle plate 120 and the pot body 110 are integrally die-cast or integrally welded.

[0100] like Figure 3 and Figure 5 As shown, in some embodiments, the projection of the first cavity 1111 along the vertical direction is rectangular, having a length direction (i.e., Figure 3 (top and bottom direction) and width direction (i.e.) Figure 3 (in the left-right direction). Regarding the first heating element 131, the first coupling terminal 1312 can be located on one side of the first cavity 1111 along its own length direction, for example, located on... Figure 3 The first heating element 131 is positioned in the upper middle part of the cavity. This arrangement ensures that the entire first heating element 131 is located within the vertical projection of the first cavity 1111, reducing assembly interference and heating interference between the first heating element 131 and the second heating element 132.

[0101] like Figure 4 andFigure 6 As shown, alternatively, the first coupling terminal 1312 corresponding to the first heating element 131 can be located on one side of the width direction of the first cavity 1111 and positioned close to the second heating element 132. It can be understood that the width direction of the first cavity 1111 is... Figure 4 The left and right direction is the same as the length direction of the pot cavity 111. Therefore, this setting is equivalent to adjusting the position of the first coupling terminal 1312 to the bottom of the pot body 110 near the center area, so as to avoid the liquid left along the edge of the pot body 110 from contacting the first coupling terminal 1312 and causing contamination or short circuit.

[0102] In actual use, the cooking pot body 100 needs to be mounted on a base 200. The base 200 is equipped with a first coupler 210 that mates with the first coupling terminal 1312 and a second coupler 220 that mates with the second coupling terminal 1322. Because when the first coupling terminal 1312 is positioned close to the center of the pot body 110, the first coupler 210 is also positioned correspondingly in the center of the base 200, thus facilitating a short circuit to the first coupler 210 caused by liquid spreading from the edge of the pot body 110 and dripping onto the base 200.

[0103] The second coupling terminal 1322 can also be located near the center of the pot body 110, and the second coupler 220 can be located near the center of the base 200.

[0104] like Figure 4 As shown, in some embodiments, the first coupling terminal 1312 may protrude beyond the vertical projection of the first cavity 1111 to ensure the length of the first effective heating section 1311. It is understood that no heat is generated at the coupling terminal; therefore, a portion of the second cavity 1112 can be used for the arrangement of the first coupling terminal 1312, thereby ensuring that the first effective heating section 1311 has sufficient length to meet the rapid boiling requirements of the first cavity 1111.

[0105] The first heating element 131 is U-shaped, but it can also be elliptical or racetrack-shaped.

[0106] Alternatively, the second coupling terminal 1322 of the second heating tube 132 can also be located on the side close to the first heating tube 131, in which case the first coupler 210 and the second coupler 220 can both be located near the center area of ​​the base 200.

[0107] Please see Figures 1 to 4In some embodiments, the heating power of the first heating element 131 is X, the heating power of the second heating element 132 is Y, and the heating assembly 130 has a first state and a second state. In the first state, the heating power of the first heating element 131 and the heating power of the second heating element 132 satisfy: X > Y, and 1000W ≤ X ≤ 2200W;

[0108] In the second state, the heating power of the first heating element 131 satisfies: 300W≤X≤900W.

[0109] In other words, in the first state, the heating power of the first heating element 131 can be adjusted to be greater than that of the second heating element 132 to heat the smaller volume of the first cavity 1111 with high power, thus achieving rapid boiling. After boiling, the system can switch to the second state, reducing the heating power of the first heating element 131 to maintain the boiling state in the first cavity 1111, and correspondingly increasing the heating power of the second heating element 132 to bring the liquid in the second cavity 1112 to a boil.

[0110] Of course, the heating power of the first heating tube 131 in the first state should not be too large, and needs to satisfy: X+Y=2200W; and, since the volume of the second cavity 1112 is large and the amount of liquid stored in it is large, the heating power of the second heating tube 132 in the first state should not be too small, otherwise the liquid in the second cavity 1112 will heat up too slowly.

[0111] In some specific embodiments, in the first state, the heating power of the first heating element 131 can be 1000W, 1500W, 1800W, 2000W, or 2200W. In the second state, the heating power of the first heating element 131 can be 300W, 500W, 650W, 800W, or 900W.

[0112] Please see Figures 5 to 8 Another embodiment of this application provides an electric hot pot, including a base 200 and the aforementioned cooking pot body 100, with the cooking pot body 100 supported on the base 200. A raised boss 230 is provided in the central region of the base 200, and both the first coupler 210 and the second coupler 220 are disposed on the boss 230. Simultaneously, the base 200 is provided with a drain hole 2001 located on the outer periphery of the boss 230. This arrangement effectively raises the assembly position of the first coupler 210 and the second coupler 220, facilitating the smooth flow of liquid to the outer periphery of the boss 230 and its discharge through the drain hole 2001, reducing the risk of short circuits between the first coupler 210 and the second coupler 220. The electric hot pot also includes a lid 300, which can be fastened to the opening of the cooking pot body 100.

[0113] 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.

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 protection scope of this application.
