Description

Technical Field

[0001] The utility model relates to the field of small household appliances, in particular to a cooking utensil. Background Art

[0002] A cooking appliance, such as an electric hot pot, generally comprises a base, a heating element and a pot body, wherein the heating element is fixed in the base and the pot body can be placed on the heating element. When the pot body is placed on the base assembly, in order to make the bottom wall of the pot body contact with the heating element, at least part of the pot body is also located in the cavity of the base.

[0003] Although the above method can protect the heating element, it causes the overall thickness of the base assembly to be larger and the cost is also higher. Utility Model Content

[0004] In view of this, it is necessary to provide a cooking utensil to address the above problems, which can reduce the thickness of the heating base and reduce the cost.

[0005] The utility model provides a cooking utensil, comprising a heating base and a pot body, wherein the heating base comprises a base body and a heating plate, wherein the heating plate is at least partially arranged in the base body, and the top surface of the heating plate is higher than the top surface of the base body, and the pot body is detachably arranged on the heating base, and when the pot body is placed on the heating base, the bottom surface of the pot body can be tightly attached to the top surface of the heating plate.

[0006] In the above cooking utensil, the heating base is used to support the pot body, the heating plate is used to heat the pot body, and the bottom surface of the pot body is in close contact with the top surface of the heating plate to ensure the heat transfer effect between the pot body and the heating plate. Since the base body does not need to wrap the entire heating plate, and the pot body does not need to be accommodated in the base body, the overall thickness of the base body can be reduced, thereby reducing the production and processing difficulty of the base body and the heating plate, reducing costs, and also reducing the overall volume of the heating base, reducing the occupied space, and facilitating storage.

[0007] In one of the embodiments, the dimension L of the top surface of the heating plate higher than the top surface of the base body satisfies 1mm≤L≤40mm.

[0008] Such an arrangement enables the bottom wall of the pot body to fully contact the top surface of the heating plate to ensure the heat transfer effect; at the same time, it can prevent the heating plate from being too high, which would lead to an excessive overall thickness of the base body and the heating plate.

[0009] In one embodiment, the base body includes a shell and an annular connecting member, the connecting member is connected to the upper edge of the shell, or the connecting member is connected to the inner side of the upper end of the side wall of the shell.

[0010] In this configuration, the shell is used to accommodate part of the heating plate and other components inside the heating base, and the connecting piece can cover the portion of the shell that is not covered by the heating plate to protect the components inside the shell.

[0011] In one embodiment, the heating base further comprises a plurality of positioning ribs, wherein the plurality of positioning ribs are arranged at intervals along the circumference of the shell or the connecting member, and when the pot body is placed on the heating plate, the positioning ribs abut against the bottom wall and / or side wall of the pot body.

[0012] With such arrangement, the positioning rib is used to support the pot body when it abuts against the bottom wall of the pot body, and is used to position the pot body when it abuts against the side wall of the pot body, which makes it easy for the user to install the pot body and prevents the pot body from shaking relative to the heating base.

[0013] In one embodiment, each of the positioning ribs has a guiding slope, and each of the guiding slopes extends obliquely upward and outward from the top surface of the base body.

[0014] With such an arrangement, multiple guide slopes can form a space with a larger opening at the upper end and a smaller opening at the lower end. When the pot body is placed on the heating plate, the guide slopes can be abutted against the outer periphery of the bottom wall of the pot body, so that the pot body moves relative to the heating base and the heating plate, and the pot body gradually aligns with the heating plate.

[0015] In one embodiment, the positioning rib is in one or more of a flame shape, a wave shape, a peak shape, a sawtooth shape, a circle, an ellipse, a triangle, and a trapezoid.

[0016] In one of the embodiments, when the pot body is placed on the heating base, a first heat dissipation gap is provided between the bottom surface of the pot body and the top surface of the base body.

[0017] With such arrangement, the hot air below the heating plate can dissipate heat through the first heat dissipation gap, thereby preventing the temperature of the component below the heating plate from being too high and affecting the normal use of the component.

[0018] In one embodiment, the heating base further includes a reflective cover disposed in the base body, the reflective cover is located below the heating plate, and a second heat dissipation gap is provided between a side edge of the heating plate and a cover surface of the reflective cover.

[0019] In this arrangement, the reflective cover is used to reflect the heat radiated downward by the heating plate toward the pot body, and the protrusion causes the heating plate to be lifted upward to a position where the top surface of the heating plate protrudes from the top surface of the base body, thereby facilitating the installation of the heating plate; the hot air between the heating plate and the reflective cover can be discharged through the second heat dissipation gap, thereby preventing the ambient temperature between the heating plate and the reflective cover from being too high and affecting the normal use of other nearby components.

[0020] In one of the embodiments, a through hole is provided at the center of the heating plate, and a protrusion is correspondingly provided on the bottom surface of the pot body.

[0021] Such a configuration can facilitate the user to position the pot body, ensure that the bottom wall of the pot body can fit with the heating plate, and the pot body will not shake relative to the heating plate, thereby improving the heat transfer effect between the pot body and the heating plate.

[0022] In one embodiment, the bottom surface of the pot body is concave inward, and the top surface of the heating plate is correspondingly configured to be convex.

[0023] Such an arrangement can facilitate the user to position the pot body, and ensure that the bottom wall of the pot body can fit with the heating plate, thereby ensuring the heat transfer effect between the pot body and the heating plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0035] A cooking appliance, such as an electric hot pot, generally comprises a base, a heating element and a pot body, wherein the heating element is fixed in the base and the pot body can be placed on the heating element. When the pot body is placed on the base assembly, in order to make the bottom wall of the pot body contact with the heating element, at least part of the pot body is also located in the cavity of the base. Although the above method can protect the heating element, it causes the overall thickness of the base assembly to be larger and the cost is also higher.

[0036] In order to solve the above problems, Figures 1 to 7 As shown, the utility model provides a cooking utensil, which can reduce the overall thickness of the heating base and reduce the cost.

[0037] like Figure 1 and Figure 4 As shown, specifically, the cooking utensil includes a heating base 10 and a pot body 30, the heating base 10 includes a base body and a heating plate 20, the heating plate 20 is at least partially arranged in the base body, and the top surface of the heating plate 20 is higher than the top surface of the base body, the pot body 30 is detachably arranged on the heating base 10, and when the pot body 30 is placed on the heating base 10, the bottom surface of the pot body 30 can be tightly attached to the top surface of the heating plate 20.

[0038] In the cooking utensil provided by the utility model, the heating base 10 is used to support the pot body 30, the heating plate 20 is used to heat the pot body 30, and the bottom surface of the pot body 30 is in close contact with the top surface of the heating plate 20 to ensure the heat transfer effect between the pot body 30 and the heating plate 20. Since the base body does not need to wrap the entire heating plate 20, and the pot body 30 does not need to be accommodated in the base body, the thickness of the base body can be reduced, thereby reducing the difficulty of production and processing of the base body and the heating plate 20 and reducing costs. In addition, the reduction in the thickness of the base body also reduces the overall volume of the heating base 10, thereby reducing the occupied space and facilitating storage.

[0039] like Figure 5 As shown, the top surface of the heating plate 20 is higher than the top surface of the base body by a dimension L, and satisfies 1mm≤L≤40mm. L≥1mm enables the bottom wall of the pot body 30 to fully contact the top surface of the heating plate 20 to ensure the heat transfer effect between the heating plate 20 and the pot body 30; L≤40mm can prevent the heating plate 20 from being too high, resulting in an excessive overall thickness of the base body and the heating plate 20, and avoid occupying too much storage space.

[0040] The top surface of the heating plate 20 is used to support the pot body 30, and the top surface can be a plane or a curved surface with a certain curvature. When the top surface of the heating plate 20 is a plane, the dimension L of the top surface of the heating plate 20 higher than the top surface of the base body is the height difference between any point on the top surface and the top surface of the base body.

[0041] When the top surface of the heating plate 20 is a curved surface, the dimension L of the top surface of the heating plate 20 above the top surface of the base body can be the height difference between the highest point on the top surface and the top surface of the base body, or can be the height difference between the lowest point or any point on the top surface and the top surface of the base body. In addition, when the top surface of the heating plate 20 is a curved surface with a certain curvature, the bottom surface of the pot body 30 is concave inward, and the top surface of the heating plate 20 is correspondingly set to a convex surface. This can also facilitate the user to position the pot body 30, and ensure that the bottom wall of the pot body 30 can fit with the heating plate 20, thereby ensuring the heat transfer effect between the pot body 30 and the heating plate 20.

[0042] like Figure 2 As shown, the base body includes a shell 11 and an annular connecting member 12, and the connecting member 12 is connected to the upper edge of the shell 11, or the connecting member 12 is connected to the inner side of the upper end of the side wall of the shell 11. The shell 11 is used to accommodate part of the heating plate 20 and other components inside the heating base 10. Since the size of the heating plate 20 is smaller than that of the shell 11, the connecting member 12 can cover the part of the shell 11 that is not covered by the heating plate 20 to protect the internal components of the shell 11.

[0043] Specifically, the housing 11 includes a bottom shell 113 and an annular outer shell 114 connected to the bottom shell 113, and the connecting member 12 is connected to one end of the outer shell 114 away from the bottom shell 113. The bottom shell 113, the outer shell 114 and the connecting member 12 can be an integrally formed setting, which is convenient for production and processing, or a split structure, and fixedly connected by welding, screws, etc. Of course, the bottom shell 113 and the outer shell 114 can also be an integral structure, and the connecting member 12 can be fixedly connected to the outer shell 114 by welding, screws, etc.; or the connecting member 12 and the outer shell 114 can be an integral structure, and the bottom shell 113 and the outer shell 114 can be fixedly connected by welding, screws, etc.

[0044] like Figures 1 to 3 As shown, the heating base 10 further includes a plurality of positioning ribs 15, which are arranged at intervals along the circumference of the housing 11 or the connecting member 12, and when the pot body 30 is placed on the heating plate 20, the positioning ribs 15 abut against the bottom wall or side wall of the pot body 30. Among them, all the positioning ribs 15 may abut against the bottom wall of the pot body 30; all the positioning ribs 15 may abut against the side wall of the pot body 30; or, some of the positioning ribs 15 may abut against the bottom wall of the pot body 30, and some of the positioning ribs 15 may abut against the side wall of the pot body 30.

[0045] Specifically, a plurality of positioning ribs 15 are arranged at intervals along the circumference of the connecting member 12. When the pot body 30 is placed on the heating plate 20, the bottom wall or side wall of the pot body 30 abuts against the positioning ribs 15, and a third heat dissipation gap is formed between the bottom wall of the pot body 30, two adjacent positioning ribs 15, and the top surface of the connecting member 12. The positioning ribs 15 are used to support the pot body 30 when they abut against the bottom wall of the pot body 30, and are used to position the pot body 30 when they abut against the side wall of the pot body 30, so that the user can install the pot body 30, and at the same time, the pot body 30 can be prevented from shaking relative to the heating base 10, so as to ensure that the pot body 30 can be stably and reliably mounted on the heating plate 20 and fit with the heating plate 20, thereby improving the heat transfer effect between the pot body 30 and the heating plate 20. In addition, the hot air under the heating plate 20 can be dissipated through the third heat dissipation gap, so as to prevent the temperature of the components under the heating plate 20 from being too high and affecting the normal use of the components.

[0046] In the illustrated embodiment, the number of the positioning ribs 15 is four, and the four positioning ribs 15 are evenly spaced along the circumference of the connecting member 12 to ensure the balance and stability of the pot body 30. At this time, the third heat dissipation gaps are also four. Of course, in other embodiments, the number of the positioning ribs 15 can also be two, three or more, the number of the third heat dissipation gaps corresponds to the positioning ribs 15, and the multiple positioning ribs 15 can also be arranged at uneven intervals, as long as the positioning and support effects of the pot body 30 can be ensured, the embodiment of the utility model is not specifically limited here.

[0047] Among them, the positioning rib 15 can be one or more of flame-shaped, wave-shaped, peak-shaped, serrated, circular, elliptical, triangular, trapezoidal, and of course, can also be other regular or irregular shapes, as long as it can limit the radial movement of the pot body 30 relative to the heating base 10. The embodiment of the utility model does not make specific restrictions here.

[0048] like Figure 3 and Figure 7 As shown, each positioning rib 15 has a guiding bevel 151, and each guiding bevel 151 extends upward and outward from the top surface of the base body. In other words, multiple guiding bevels 151 can form a funnel-like structure in the circumferential direction. That is, along the thickness (height) direction of the base body, the opening of the funnel-shaped structure formed by multiple guiding bevels 151 gradually increases from the base body upward. In this way, the guiding bevel 151 can further facilitate the user to position the pot body 30 and the heating base 10. When the pot body 30 is placed on the heating plate 20, even if the pot body 30 and the heating plate 20 are not completely aligned, the guiding bevel 151 can be against the outer periphery of the bottom wall of the pot body 30, so that the pot body 30 moves relative to the base body and the heating plate 20, and the pot body 30 gradually aligns with the heating plate 20, so that it is convenient for the user to install the pot body 30. Among them, the guiding bevel 151 can be a plane, a curved surface or an irregular curved surface.

[0049] like Figure 7 As shown, the height of the positioning rib 15 is greater than or equal to the distance between the bottom wall of the pot body 30 and the top surface of the connecting member 12. It can be understood that the higher the height of the positioning rib 15, the larger the opening on the upper side of the funnel-shaped structure, so that the guiding effect of the positioning rib 15 on the pot body 30 can be improved, and it is further convenient for the user to align and install the pot body 30. In addition, when the pot body 30 is placed on the heating plate 20, the positioning rib 15 can be against the outer periphery of the bottom of the pot body 30 or the side wall of the pot body 30, so as to prevent the pot body 30 from shaking relative to the heating base 10, or from tipping over or even sliding from the side of the heating base 10, further improving the stability and reliability of the pot body 30 on the heating plate 20, thereby improving the safety of the pot body 30 during use.

[0050] It is worth mentioning that, since the third heat dissipation gap is formed between the bottom wall of the pot body 30, two adjacent positioning ribs 15 and the top surface of the connecting member 12, the height of the third heat dissipation gap refers to the distance between the bottom wall of the pot body 30 and the top surface of the connecting member 12 in the height direction. In other embodiments, a recessed groove may be provided in the portion of the connecting member 12 between two adjacent positioning ribs 15 to further increase the area of ​​the third heat dissipation gap or increase the height of the third heat dissipation gap.

[0051] like Figure 1As shown, when the pot body 30 is placed on the heating plate 20, an annular circumferential surface is formed between the bottom wall of the pot body 30 and the top surface of the base body, and the circumferential surface is formed by the cross section where the third heat dissipation gap is located and the cross section where the positioning rib 15 is located along the circumferential direction, wherein the sum of the cross-sectional areas of the positioning rib 15 is smaller than the sum of the cross-sectional areas of the third heat dissipation gap. For example: when the base body is a circular structure as shown in the figure, the sum of the circumferential angles occupied by the projection of the third heat dissipation gap on the base body is greater than the sum of the circumferential angles occupied by the projection of the positioning rib 15 on the base body. In this way, the third heat dissipation gap can be ensured to be large enough to ensure the heat dissipation effect, and to avoid the temperature of the component below the heating plate 20 being too high and affecting the normal use of the component.

[0052] like Figure 3 and Figure 7 As shown, in the illustrated embodiment, the positioning rib 15 is provided on the connecting member 12 and is integrally formed with the connecting member 12. This ensures the reliability of the connection between the positioning rib 15 and the connecting member 12, and also facilitates the production and processing of the heating base 10. Of course, in other embodiments, the positioning rib 15 can also be fixedly connected to the connecting member 12 by welding, screws, etc.; or, the positioning rib 15 can also be fixedly provided on the upper edge of the shell 114 of the shell 11, as long as the positioning rib 15 can ensure the positioning and support effect of the pot body 30, the embodiment of the utility model is not specifically limited here.

[0053] like Figure 2 and Figure 4 As shown, although the heating plate 20 is used to heat the pot body 30 located on the upper side of the heating plate 20, the heat generated by the heating plate 20 will also gather under the heating plate 20, causing the surrounding ambient temperature to rise, and the components located under the heating plate 20 are easily damaged when they are in a high temperature state for a long time. Therefore, when the pot body 30 is placed on the heating base 10, there is a first heat dissipation gap between the bottom surface of the pot body 30 and the top surface of the base body. The hot air under the heating plate 20 can dissipate heat through the first heat dissipation gap to prevent the temperature of the components under the heating plate 20 from being too high and affecting the normal use of the components. In addition, since the density of hot air is smaller than that of cold air, the hot air will flow upward, so the first heat dissipation gap helps to improve the heat dissipation effect.

[0054] like Figure 2 and Figure 5As shown, the bottom wall of the shell 11 has a heat dissipation area 111 protruding toward the inside of the shell 11, and a heat dissipation port 112 is provided on the heat dissipation area 111. The heat dissipation area 111 protrudes toward the inside of the shell 11, so that when the base body is placed on an external plane such as a desktop, there is a certain gap between the bottom surface of the heat dissipation area 111 and the external plane, and the gap allows air to circulate. Since the temperature of the components in the base body may also rise during operation, the hot air in the base body can be dissipated through the heat dissipation port 112 of the heat dissipation area 111 to prevent the temperature of the components in the base body from being too high and affecting the normal use of the components.

[0055] like Figures 4 to 5 As shown, the heat dissipation area 111 is located below the heating plate 20. In this way, the heat dissipation port 112 is connected to the first heat dissipation gap, and the cold air from the outside can enter the bottom of the heating plate 20 through the heat dissipation port 112, and the hot air under the heating plate 20 can be discharged through the first heat dissipation gap, thereby achieving air circulation and improving the heat dissipation effect. Alternatively, the cold air from the outside can enter the bottom of the heating plate 20 through the first heat dissipation gap, and the hot air under the heating plate 20 can be discharged through the heat dissipation port 112.

[0056] like Figure 2 and Figure 4 As shown, in one embodiment, the heating base 10 further includes a reflector 13 disposed in the base body, the reflector 13 is located below the heating plate 20, and a second heat dissipation gap is provided between the side edge of the heating plate 20 and the cover surface of the reflector 13. The reflector 13 is used to reflect the heat radiated downward from the heating plate 20 toward the pot body 30, so as to reduce heat loss and improve the cooking effect, and also reduce the impact of the heating plate 20 on the lower components. In addition, the hot air between the heating plate 20 and the reflector 13 can be discharged through the second heat dissipation gap and the first heat dissipation gap, so as to avoid the ambient temperature between the heating plate 20 and the reflector 13 being too high and affecting the normal use of other nearby components.

[0057] Furthermore, a convex column 131 is provided on one side of the reflector 13 facing the heating plate 20, and the heating plate 20 is fixed on the convex column 131. The convex column 131 allows the heating plate 20 to be lifted upward to a position where the top surface of the heating plate 20 protrudes from the top surface of the base body, which facilitates the installation of the heating plate 20.

[0058] like Figure 2 and Figure 5As shown, the reflector 13 is provided with an avoidance hole 132. External air enters the base body through the heat dissipation port 112, and is discharged from the first heat dissipation gap through the avoidance hole 132 and the second heat dissipation gap, thereby realizing air circulation between the base body as a whole and the outside, further improving the heat dissipation effect. Alternatively, external air may enter the base body through the first heat dissipation gap, and be discharged from the heat dissipation port 112 through the second heat dissipation gap and the avoidance hole 132. The avoidance hole 132 on the reflector 13 can also be used to pass cables or to avoid other components in the base body.

[0059] In another embodiment, the reflector 13 may not be provided in the base body. In this case, the heat dissipation port 112 is directly connected to the first heat dissipation gap to achieve air circulation between the base body and the outside.

[0060] like Figure 3 to Figure 4 As shown, in one embodiment, a through hole 21 is provided at the center of the heating plate 20, and a protrusion 31 is provided on the bottom surface of the pot body 30. The cooperation between the protrusion 31 and the through hole 21 can facilitate the user to position the pot body 30, ensure that the bottom wall of the pot body 30 can fit with the heating plate 20, and the pot body 30 will not shake relative to the heating plate 20, thereby improving the heat transfer effect between the pot body 30 and the heating plate 20. In addition, the protrusion 31 and the through hole 21 are not easily deformed, so as to ensure that the bottom wall of the pot body 30 can always fit with the heating plate 20. Since the through hole 21 of the heating plate 20 will not heat the protrusion 31 on the bottom wall of the pot body 30, the through hole 21 and the protrusion 31 only play a role in positioning the pot body 30 and the heating plate 20, the protrusion 31 and the through hole 21 on the bottom wall of the pot body 30 and the heating plate 20 can occupy a small space, so that the pot body 30 and the heating plate 20 can be easily produced and processed, and the installation space of other structures such as the heating tube on the heating plate 20 is avoided, so as to ensure the heating efficiency of the heating plate 20 on the pot body 30. Of course, in other embodiments, a protrusion can also be provided at the center of the heating plate 20, and a groove can be provided on the bottom surface of the pot body 30 accordingly.

[0061] like Figure 1 As shown, the cooking utensil can be configured as an electric hot pot, an electric steamer, an electric stew pot, an electric rice cooker, or the like, wherein the pot body 30 can be detachably mounted on the heating base 10, and the embodiment of the utility model does not impose any specific limitation thereto.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
