Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a bracket and an electric stew pot. Background Art

[0002] The existing electric stew pot includes a heating base, a pot body and an inner pot. The inner pot is located in the pot body. The heating base heats the liquid in the pot body, and the liquid heats the food in the inner pot, thereby heating the food in the inner pot.

[0003] When the electric stew pot is working, the temperature difference of the heating surface of the electric heating plate is large, and local supercooling boiling occurs, generating a large number of bubbles. During the rising process of the bubbles, they are blocked by the pad and the inner pot, and the small bubbles aggregate to form large bubbles. Eventually, the large bubbles float to the surface and break, producing the noise of larger bubbles breaking, and even causing the inner pot to shake. The noise mainly dissipates outward through the air vents. When the noise is large, it will affect the user experience. Utility Model Content

[0004] In view of this, it is necessary to provide a bracket and an electric stew pot to address the above problems, so as to reduce the noise generated when the electric stew pot is working.

[0005] The utility model first provides a bracket for use in an electric stew pot, comprising: a tray, comprising a supporting portion and a connecting portion connected to the periphery of the supporting portion, wherein a plurality of first channels are provided on the connecting portion, each of the first channels is arranged to penetrate along the thickness direction of the tray, and each of the first channels comprises a gradually expanding section, wherein the cross-sectional area of the gradually expanding section gradually increases along the direction from the bottom to the top of the tray; and supporting legs, which are provided on the tray and are used to support the tray in the electric stew pot.

[0006] In the above-mentioned bracket, the bubbles below the bracket will rise through the gradually expanding sections of the multiple first channels on the connecting part. When the bubbles pass through the small diameter end of the gradually expanding section, they will neck and break into small bubbles and rise toward the large diameter end of the gradually expanding section to leave the first channel. In addition, the gradually increasing cross-sectional area of the gradually expanding section can also prevent the bubbles from blocking the gradually expanding section, so that the bubbles can better rise and leave the first channel. Since the floating bubbles are all small bubbles with smaller diameters, the noise generated when the small bubbles float to the surface and break is smaller, thereby reducing the noise generated when the electric stew pot is working, and the impact force generated when the small bubbles break is also smaller, thereby reducing the shaking noise generated by the electric stew pot and improving the user experience.

[0007] In one embodiment, the first channel further includes a tapered section, the cross-sectional area of which gradually decreases from the bottom to the top of the tray, and the small diameter end of the tapered section is connected to the small diameter end of the gradually expanding section.

[0008] With such a configuration, the bubbles generated by the heating plate during operation will rise in sequence through the tapered section and the gradually expanding section. The tapered section can accelerate the thermal convection of the fluid and form a negative pressure in the tapered section to attract the bubbles under the bracket into the tapered section and the gradually expanding section, preventing the bubbles from gathering under the bracket to form large bubbles, thereby improving the bubble crushing efficiency.

[0009] In one embodiment, the first channel further includes a constant diameter section extending from the bottom toward the top of the tray, and the top end of the constant diameter section is connected to the small diameter end of the gradually expanding section.

[0010] With this arrangement, the bubbles generated by the heating plate during operation will rise in sequence through the constant diameter section and the gradually expanding section. The constant diameter section extends the path for the bubbles to undergo necking and breaking, thereby better breaking large bubbles into small bubbles and improving the bubble breaking effect.

[0011] In one embodiment, the first channel further includes a tapered section, and along the direction from the bottom to the top of the tray, the lower end of the equal diameter section is connected to the small diameter end of the tapered section.

[0012] With such arrangement, the bubbles generated by the heating plate during operation will rise in sequence through the tapered section, the equal diameter section and the gradually expanding section. The tapered section can attract the bubbles under the bracket into the tapered section, the equal diameter section and the gradually expanding section. When the bubbles pass through the small diameter ends of the equal diameter section and the gradually expanding section, they will neck and break into small bubbles and rise toward the large diameter end of the gradually expanding section to leave the first channel. The gradually expanding section can prevent the bubbles from blocking the equal diameter section, thereby improving the bubble breaking efficiency and effect.

[0013] In one embodiment, the angle of the tapered section is α, and the angle of the diverging section is β, then α>β.

[0014] Such an arrangement ensures that the inlet of the tapered section is always in a negative pressure state, thereby being able to always maintain an attraction effect on the bubbles below the bracket.

[0015] In one embodiment, a plurality of protrusions are provided on the connecting portion, and the first channel is provided in each of the protrusions.

[0016] With such arrangement, the protrusion can increase the local thickness of the support portion, so as to facilitate processing of the first channel at the protrusion.

[0017] In one embodiment, a plurality of the first channels are spaced apart along the circumference of the connecting portion.

[0018] Such an arrangement and the circumferential spacing arrangement are beneficial to expanding the coverage area of the first channel and eliminating bubbles better and more.

[0019] In one embodiment, a guide surface is further provided on the bottom surface of the tray, and the guide surface extends obliquely downward from the bottom end of the first channel toward the middle of the support portion.

[0020] With this arrangement, the bubbles gathered on the guide surface can move along the guide surface toward the first channel, thereby better guiding the bubbles into the first channel and preventing the bubbles from gathering under the bracket to form large bubbles.

[0021] In one embodiment, the guide surface is a curved surface, a flat surface, or a trapezoidal surface.

[0022] With such arrangement, the guide surface can better guide the bubbles into the first channel, and the structure is simple and easy to process.

[0023] In one embodiment, the tray has a planar cross section.

[0024] With such arrangement, the cross section of the tray is flat, that is, the tray has a flat plate structure, which is simple in structure and easy to process.

[0025] In one embodiment, the tray further includes a buffer seat and a buffer member disposed on the buffer seat, the buffer seat is disposed in a central area of the guide surface, and a lower surface of the buffer seat is higher than a lower surface of the support leg.

[0026] With such arrangement, the buffer member can prevent the buffer seat from contacting the heating plate and reduce the heat exchange area of the heating plate, thereby ensuring heat exchange efficiency.

[0027] In one embodiment, the lower surface of the buffer member is flush with the lower surface of the leg.

[0028] Such an arrangement enables both the legs and the buffer member to be used to support the bracket, thereby improving the overall stability of the bracket.

[0029] In one embodiment, the buffer member is a flexible member.

[0030] With such arrangement, the buffer member can play a buffering role and absorb the vibration of the cooking equipment caused by heat convection or bubble collapse impact, thereby reducing the generation of noise.

[0031] The utility model also provides an electric stew pot, comprising: a heating base, comprising an outer shell and a heating plate located inside the outer shell, wherein the heating plate and the outer shell form a heating cavity; an inner pot; and the bracket, wherein the bracket is arranged in the heating cavity and above the heating plate, the legs are arranged on the bottom wall of the heating cavity, and the inner pot is placed on the support portion.

[0032] In one embodiment, the projection of the bottom wall of the inner pot on the plane where the bracket is located is located within the projection area of the first channel on the plane where the bracket is located; or the projection edge of the bottom wall of the inner pot on the plane where the bracket is located coincides with the projection of the first channel on the plane where the bracket is located.

[0033] This arrangement prevents the bubbles from being blocked by the bottom wall of the inner pot placed on the support portion after passing through the first channel, thereby preventing the bubbles from aggregating into large bubbles on the bottom wall of the inner pot.

[0034] In one embodiment, the support portion includes a first rib and a second rib radially spaced apart, each of the first rib and the second rib is provided with a corresponding notch, the first rib, the second rib and the support portion are arranged to form a positioning groove, and the bottom wall of the inner pot is provided with a positioning protrusion that cooperates with the positioning groove.

[0035] With such a configuration, the first convex rib and the second convex rib can limit the inner pot, and at the same time can also improve the strength of the support part, ensuring the stability and reliability of the support part in supporting the inner pot; the setting of the notch allows the liquid in the areas inside and outside the first convex rib and the second convex rib to circulate with each other, so as to ensure the heat exchange efficiency of the area above the support part.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component. When a component is considered to be "fixed to" another component, it may be directly fixed to the other component or there may be a central component.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] An electric stew pot consists of a heating base, a pot body, and an inner pot. The inner pot is located within the pot body. The heating base heats the liquid within the pot body, which in turn heats the ingredients within the inner pot. When the electric stew pot is in operation, the heating surface of the electric heating plate experiences a large temperature difference, causing localized supercooling and boiling, which generates a large number of bubbles. As these bubbles rise, they are blocked by the support and inner pot, causing small bubbles to aggregate and form larger bubbles. These bubbles eventually surface and burst, producing a loud noise. Simultaneously, the impact of these bubbles acts on the stew pot, causing the inner pot to shake and make noise, impacting the user experience.

[0052] In order to solve the above problems, Figures 1 to 11 As shown, the present application provides a bracket and an electric stew pot, wherein the bracket is used in the electric stew pot to reduce the noise generated when the electric stew pot is working.

[0053] like Figure 1 and Figure 11 As shown, the electric stew pot includes a heating base 200, an inner pot 300, and a support 100. The heating base 200 includes a housing 201 and a heating plate 202 located within the housing 201. The heating plate 202 and the housing 201 form a heating chamber 203. The support 100 is disposed within the heating chamber 203 and above the heating plate 202. The inner pot 300 is placed on the support 100. When the electric stew pot is in operation, the heating chamber 203 is filled with liquid such as water. The heating plate 202 heats the liquid in the heating chamber 203, and the liquid in the heating chamber 203 heats the inner pot 300 on the support 100.

[0054] like Figures 1 to 4 As shown, the bracket 100 includes a tray 10 and a leg 20, wherein: the tray 10 includes a support portion 11 and a connecting portion connected to the periphery of the support portion 11, and a plurality of first channels 12 are provided on the connecting portion, each first channel 12 is arranged to pass through along the thickness direction of the tray 10, and each first channel 12 includes a gradually expanding section 122, which extends from the bottom to the top of the tray 10, and the cross-sectional area of the gradually expanding section 122 gradually increases; the leg 20 is provided on the tray 10, and is used to support the tray 10 in the electric stew pot.

[0055] The legs 20 are disposed on the bottom wall of the heating chamber 203 to mount the bracket 100 in the heating chamber 203 , and the inner pot 300 is placed on the support portion 11 .

[0056] In the bracket 100 provided by the embodiment of the present invention, since the bracket 100 is located above the heating plate 202, the bubbles generated by the heating plate 202 during operation will rise through the gradually expanding sections 122 of the multiple first channels 12 on the periphery of the support part 11. When the bubbles pass through the small diameter end of the gradually expanding section 122, they will neck and break into small bubbles and rise toward the large diameter end of the gradually expanding section 122 to leave the first channel 12. In addition, the gradual increase in the cross-sectional area of the gradually expanding section 122 can also prevent the bubbles from blocking the gradually expanding section 122, so that the bubbles can better rise and leave the first channel 12. Since the floating bubbles are all small bubbles with smaller diameters, the noise generated when the small bubbles float to the surface and break is smaller, thereby reducing the noise generated when the electric stew pot is working, and the impact force generated when the small bubbles break is also smaller, thereby reducing the shaking noise generated by the electric stew pot and improving the user experience.

[0057] Furthermore, the first channel 12 is located outside the support portion 11 , so that bubbles will not be blocked by the inner pot 300 placed on the support portion 11 after passing through the first channel 12 , thereby preventing the bubbles from aggregating into large bubbles on the outer wall of the inner pot 300 .

[0058] like Figures 1 to 3 As shown, in one embodiment, legs 20 extend downward from the tray 10 and are mounted on the bottom wall of the heating chamber 203. Multiple legs 20 are provided, spaced apart along the periphery of the tray 10 to ensure the stability of the bracket 100 within the heating chamber 203. This also prevents the legs 20 from blocking air bubbles from moving toward the first channel 12 and causing them to aggregate into large bubbles at the legs 20. Of course, in other embodiments, the legs 20 may also extend outward from the periphery of the tray 10 and be secured to the sidewalls of the heating chamber 203, as long as the stability of the bracket 100 within the heating chamber 203 is ensured. This embodiment of the utility model is not particularly limited here.

[0059] like Figure 5 As shown, in one embodiment, the first channel 12 includes a constant diameter section 121 and a gradually expanding section 122. Along the direction from the bottom to the top of the tray 10, the top end of the constant diameter section 121 is connected to the small diameter end of the gradually expanding section 122. When the heating plate 202 is in operation, the bubbles generated will rise through the constant diameter section 121 and the gradually expanding section 122 of the first channel 12 in sequence. When the bubbles pass through the small diameter ends of the constant diameter section 121 and the gradually expanding section 122, they will neck and break into small bubbles and rise toward the large diameter end of the gradually expanding section 122 to leave the first channel 12. The constant diameter section 121 extends the path for the bubbles to neck and break, thereby better breaking large bubbles into small bubbles and improving the bubble breaking effect. The gradually expanding section 122 can also prevent the bubbles from blocking the constant diameter section 121 and the gradually expanding section 122, so that the bubbles can better rise and leave the first channel 12.

[0060] like Figure 6As shown, in one embodiment, the first channel 12 includes a tapered section 123 and a gradually expanding section 122. The cross-sectional area of the tapered section 123 gradually decreases along the direction from the bottom to the top of the tray 10, and the small diameter end of the tapered section 123 is connected to the small diameter end of the gradually expanding section 122. The bubbles generated by the heating disk 202 during operation will rise in turn through the tapered section 123 and the gradually expanding section 122 of the first channel 12. The gradually decreasing cross-sectional area of the tapered section 123 can accelerate the thermal convection of the fluid and form a negative pressure in the tapered section 123 to attract the bubbles below the bracket 100 into the tapered section 123 and the gradually expanding section 122, thereby preventing the bubbles from gathering under the bracket 100 and forming large bubbles, thereby improving the bubble crushing efficiency; when the bubbles pass through the small diameter end of the gradually expanding section 122, they will neck and break into small bubbles and rise toward the large diameter end of the gradually expanding section 122 to leave the first channel 12, and the gradually expanding section 122 can also prevent the bubbles from blocking the gradually expanding section 122, so that the bubbles can better rise and leave the first channel 12.

[0061] like Figure 6 As shown, in one embodiment, the first channel 12 includes a tapered section 123, a constant diameter section 121 and a gradually expanding section 122, the top end of the constant diameter section 121 is connected to the small diameter end of the gradually expanding section 122, and the lower end of the constant diameter section 121 is connected to the small diameter end of the tapered section 123. The bubbles generated by the heating disk 202 during operation will rise in sequence through the tapered section 123, the equal diameter section 121 and the gradually expanding section 122 of the first channel 12. The tapered section 123 can accelerate the thermal convection of the fluid and form a negative pressure in the tapered section 123 to attract the bubbles below the bracket 100 into the tapered section 123, the equal diameter section 121 and the gradually expanding section 122, thereby preventing the bubbles from gathering under the bracket 100 and forming large bubbles; when the bubbles pass through the small diameter ends of the equal diameter sections 121 and the gradually expanding section 122, they will neck and break into small bubbles and rise toward the large diameter end of the gradually expanding section 122 to leave the first channel 12. The equal diameter section 121 extends the path for the bubbles to neck and break, thereby better breaking the large bubbles into small bubbles; and the gradually expanding section 122 can also prevent the bubbles from blocking the equal diameter section 121 and the gradually expanding section 122, so that the bubbles can better rise and leave the first channel 12, thereby improving the bubble breaking efficiency and effect.

[0062] The horizontal cross-sections of the tapered section 123, the constant diameter section 121, and the gradually expanding section 122 are all circular, so as to facilitate the passage of bubbles through the first channel 12 and also facilitate the processing of the first channel 12. Of course, the horizontal cross-sections of the tapered section 123, the constant diameter section 121, and the gradually expanding section 122 may also be square, triangular, or other regular or irregular shapes, and the present invention is not specifically limited thereto.

[0063] like Figure 4As shown, the angle α of the tapered section 123 and the angle β of the diverging section 122 are such that α>β. This allows the inlet of the tapered section 123 to be larger than the outlet of the diverging section 122, ensuring that the inlet of the tapered section 123 is always in a negative pressure state, thereby maintaining a constant suction effect on bubbles beneath the stent 100. In any vertical section passing through the centerline a of the first channel 12, the angle α is the angle between the two side walls of the tapered section 123, and the angle β is the angle between the two side walls of the diverging section 122.

[0064] like Figure 9 As shown, in another embodiment, the plurality of first channels 12 are spaced apart along the circumference of the connecting portion. Specifically, the plurality of first channels 12 can be spaced apart at equal intervals along the circumference of the connecting portion, or the plurality of first channels 12 can be spaced apart at unequal intervals along the circumference of the connecting portion, such as in a scattered or divergent pattern.

[0065] like Figure 3 and Figure 8 As shown, in one embodiment, since the overall thickness of the tray 10 is relatively thin, in order to facilitate the processing of the first channel 12 on the connecting portion, the outer thickness of the connecting portion can be increased.

[0066] like Figure 9 As shown, the connecting portion is provided with a plurality of protrusions 111, each of which is provided with a first channel 12. The protrusions 111 can also increase the thickness of the support portion 11 locally, facilitating the processing of the first channel 12 at the protrusions 111. Of course, in other embodiments, when the overall thickness of the connecting portion is sufficiently large, the outer thickness of the support portion 11 may not be increased or the protrusions 111 may not be provided, and the first channel 12 may be processed directly on the outer periphery of the support portion 11.

[0067] like Figures 2 to 3 As shown, the bottom surface of the tray 10 is further provided with a guide surface 13, which extends from the bottom end of the first channel 12 toward the middle of the support portion 11. Since bubbles move upward, the guide surface 13 extends from the middle of the support portion 11 to the bottom end of the first channel 12, allowing bubbles gathered on the guide surface 13 to move along the guide surface 13 toward the first channel 12. This can better guide the bubbles on the guide surface 13 and the bubbles below the bracket 100 into the first channel 12, preventing the bubbles from gathering below the bracket 100 and forming large bubbles, thereby improving the bubble crushing efficiency.

[0068] Specifically, the guide surface 13 can be a curved surface, a plane, or a trapezoidal surface, which can better guide the bubbles into the first channel, and has a simple structure and is easy to process. When the guide surface 13 is a curved surface, it can be a curved surface that is concave relative to the support portion 11, or it can be a curved surface that is convex relative to the support portion 11. It can be understood that, from the longitudinal section of the tray 10, the contour line where the guide surface 13 is located is an arc line. When the guide surface 13 is a plane, from the longitudinal section of the tray 10, the contour line where the guide surface 13 is located is a straight line. When the guide surface 13 is a trapezoidal surface, from the longitudinal section of the tray 10, the contour line where the guide surface 13 is located is a slant line (reference Figure 3 It is worth mentioning that the specific shapes of the guide surface 13 mentioned here are all general shapes of the whole.

[0069] Furthermore, the cross section of the tray 10 may be planar, which can be understood as the upper surface of the tray 10 being planar, the lower surface of the tray 10 being planar, and the tray 10 as a whole being a flat plate structure with a simple structure and easy processing and manufacturing.

[0070] like Figure 1 and Figure 3 As shown, the tray 10 further includes a buffer seat 14 and a buffer member 15 disposed on the buffer seat 14. The buffer seat 14 is disposed in the central area of the guide surface 13, and the lower surface of the buffer seat 14 is higher than the lower surface of the leg 20. When the leg 20 is placed in the electric stew pot, the leg 20 is supported within the inner pot of the electric stew pot. Since the buffer seat 14 is used to mount the buffer member 15, the lower surface of the leg 20 is lower than the lower surface of the buffer seat 14, preventing the buffer seat 14 from contacting the inner pot. Furthermore, the lower surface of the buffer seat 14 is higher than the lower surface of the buffer member 15, and the lower surface of the buffer member 15 can be flush with or higher than the lower surface of the leg 20. Even if the heavy inner pot 300 placed on the support 100 causes the support 100 to deform, the buffer member 15 will first contact and support the heating plate 202, thereby preventing further deformation of the buffer seat 14 and preventing contact between the buffer seat 14 and the heating plate 202, which would reduce the heat exchange area between the heating plate 202 and the water in the heating chamber 203. It can be understood that when the height difference between the lower surface of the buffer seat 14 and the lower surface of the buffer member 15 is H, the distance between the lower surface of the buffer seat 14 and the heating plate 202 is greater than or equal to H. Furthermore, because the lower surface of the buffer member 15 is much smaller than that of the buffer seat 14, even if the lower surface of the buffer member 15 contacts the heating plate 202, a sufficient heat exchange area is maintained between the heating plate 202 and the water in the heating chamber 203, ensuring heat exchange efficiency.

[0071] like Figure 1 and Figure 3As shown, in one embodiment, when the legs 20 extend downward from the tray 10, the lower surface of the buffer 15 is flush with the lower surface of the legs 20. When the legs 20 are positioned on the bottom wall of the heating chamber 203, the lower surface of the buffer 15 is in contact with the heating plate 202, so that both the legs 20 and the buffer 15 can be used to support the bracket 100, thereby improving the overall stability of the bracket 100 within the heating chamber 203.

[0072] In one embodiment, the buffer member 15 is a flexible member. When the lower surface of the buffer member 15 is in contact with the heating plate 202, the buffer member 15 can also act as a buffer and absorb vibrations generated by heat convection or bubble collapse in the cooking device, further reducing noise. Of course, in other embodiments, the buffer member 15 can also be a rigid member to stably and reliably support the bracket 100 within the heating chamber 203.

[0073] like Figure 3 As shown, in one embodiment, the buffer seat 14 is provided with a mounting hole 141, and the buffer member 15 includes a mounting section 151 and a buffer section 152 connected to each other. The mounting section 151 is locked in the mounting hole 141 to achieve a fixed connection between the buffer member 15 and the buffer seat 14, and the buffer section 152 is protruded from the lower surface of the buffer seat 14. Of course, in other embodiments, the buffer member 15 can also be integrally formed with the buffer seat 14, or be provided as a separate structure with the buffer seat 14 and fixedly connected by other means such as gluing or screwing, and the present invention is not specifically limited thereto.

[0074] like Figure 1 As shown, the diameter D1 of the buffer seat 14 is smaller than the diameter D2 of the heating plate 202 to reduce the size of the buffer seat 14 and prevent the bubbles generated by the heating plate 202 from rising and aggregating excessively in the buffer seat 14 to form large bubbles, thereby affecting the bubble breaking efficiency.

[0075] like Figure 1 As shown, the projection of the bottom wall of the inner pot 300 onto the plane of the support 100 lies within the projection of the first channel 12 onto the plane of the support 100, or the edge of the projection of the bottom wall of the inner pot 300 onto the plane of the support 100 coincides with the projection of the first channel 12 onto the plane of the support 100. The projection of the first channel 12 onto the plane of the support 100 refers to the annular area enclosed by the projections of all first channels 12 onto the plane of the support 100. The projection of the bottom wall of the inner pot 300 onto the plane of the support 100 lies within the inner ring of the annular area, or the edge of the projection of the bottom wall of the inner pot 300 onto the plane of the support 100 coincides with the annular area. This prevents bubbles from being blocked by the bottom wall of the inner pot 300 placed on the support portion 11 after passing through the first channel 12, preventing them from agglomerating into large bubbles at the bottom wall of the inner pot 300. The first channel 12 is preferably located near the edge of the support portion 11.

[0076] like Figures 8 to 10 As shown, the support portion 11 is provided with a positioning groove 16, and the bottom wall of the inner pot 300 is provided with a positioning protrusion 301 that cooperates with the positioning groove 16. When the inner pot 300 is placed on the support portion 11, the positioning protrusion 301 cooperates with the positioning groove 16 to ensure the stability of the inner pot 300 on the support 100, prevent the inner pot 300 from shifting during cooking, and facilitate the user's positioning of the inner pot 300. Furthermore, the cooperation between the positioning groove 16 and the positioning protrusion 301 ensures the relative position of the inner pot 300 and the support 100, further ensuring that bubbles rising from the first channel 12 are not blocked by the inner pot 300, preventing bubbles from agglomerating into large bubbles on the outer wall of the inner pot 300.

[0077] like Figure 8 As shown, in one embodiment, the support portion 11 is provided with a first rib 17 and a second rib 18 radially spaced apart. The first rib 17, the second rib 18, and the support portion 11 form a positioning groove 16. The first rib 17 and the second rib 18 serve to position the inner pot 300 while also enhancing the strength of the support portion 11 and ensuring the stability and reliability of the support portion 11 in supporting the inner pot 300. The first rib 17 and the second rib 18 can be circular with different diameters and, together with the support portion 11, form an annular positioning groove 16. The positioning protrusion 301 is configured as an annular or arc-shaped protrusion corresponding to the positioning groove 16, eliminating any directional restrictions between the inner pot 300 and the support 100, making it easier for the user to place the inner pot 300. Alternatively, the first rib 17 and the second rib 18 can be other shapes, such as squares or triangles, of varying sizes. The shape of the positioning protrusion 301 corresponds to the shape of the positioning groove 16 to ensure that they fit together.

[0078] In other embodiments, when the first rib 17 and the second rib 18 are concentric rings, a reinforcing rib may be provided between the first rib 17 and the second rib 18 to enhance the stability of the first rib 17 and the second rib 18 .

[0079] like Figure 8As shown, corresponding notches 19 are provided on each of the first and second ribs 17, 18. Since the support portion 11 is located on the side facing away from the heating plate 202, the notches 19 allow for fluid flow between the areas inside and outside the first and second ribs 17, 18, ensuring efficient heat exchange in the area above the support portion 11 and preventing the liquid in the first and second ribs 17, 18 from becoming too cold, thereby ensuring efficient heating of the inner pot 300. Multiple notches 19 can be provided on each of the first and second ribs 17, 18, and spaced apart circumferentially along the first or second rib 17, 18. In other embodiments, when multiple positioning grooves 16 are spaced apart circumferentially along the support portion 11, the gaps between adjacent positioning grooves 16 can also be considered notches 19, thereby enhancing heat exchange efficiency above the support portion 11.

[0080] Of course, in other embodiments, the positioning groove 16 can also be a groove in a ring or arc shape formed by the upper surface of the support part 11; or, a positioning protrusion 301 can be provided on the support part 11, and a positioning groove 16 that can cooperate with the positioning protrusion 301 can be opened on the bottom wall of the inner pot 300. As long as it can cooperate with the positioning protrusion 301 to limit the inner pot 300, the embodiment of the utility model does not make specific restrictions here.

[0081] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0082] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
