Abstract
Description
Technical Field
[0001] The utility model relates to the field of small household appliances, in particular to a cooking utensil. Background Art
[0002] Some cooking utensils, such as electric hot pots, heat the pot body through an electric heating plate. Usually, the electric heating plate is cast by centrifugal casting, and a through hole is usually formed in the center of the electric heating plate. Due to the existence of the through hole, some impurities or water can easily enter the base assembly through the through hole, which can easily cause damage to some components in the base assembly.
[0003] In order to solve the above problems, currently the through hole is mainly blocked by a hardware cover plate, and the cover plate is fixed to the electric heating plate by screws. Although this method can solve the above problems, it has many parts and complicated assembly process. Utility Model Content
[0004] In view of this, it is necessary to provide a cooking utensil for the above-mentioned problem, which has fewer parts and is easy to assemble.
[0005] The utility model provides a cooking utensil, comprising a base assembly and a pot body, wherein the base assembly comprises a shell, a cover body and a heating plate, wherein the cover body is located below the heating plate and is fixed in the shell body; wherein the heating plate is provided with a through hole, and the cover body is integrally provided with a protrusion, and the protrusion is inserted into and blocks the through hole.
[0006] In the above cooking utensil, when the heating plate is installed on the cover body, the through hole is blocked by the protrusion, and impurities or water above the heating plate will not enter the base assembly through the through hole, thereby avoiding damage to the components in the base assembly; because the protrusion is integrally provided on the cover body, additional parts such as cover plates and screws can be omitted, the number of parts can be reduced, and the assembly steps of the base assembly can also be simplified to reduce costs.
[0007] In one embodiment, the top surface of the protrusion is lower than the plate surface of the heating plate.
[0008] With such a configuration, the groove formed by the raised top surface and the inner side surface of the through hole can accumulate a small amount of impurities or water, preventing the impurities from remaining on the surface of the heating plate and pushing the pot body upward, thereby ensuring that the bottom wall of the pot body can fit with the surface of the heating plate, and the pot body will not shake relative to the heating plate, thereby ensuring the heat transfer effect between the pot body and the heating plate.
[0009] In one of the embodiments, the height difference between the top surface of the protrusion and the plate surface of the heating plate is 1 mm to 20 mm.
[0010] Such an arrangement ensures that there is enough space to accommodate impurities and water, and at the same time allows the user to easily clean up when a small amount of impurities or water enters the groove, while also avoiding an increase in the size of the base assembly due to excessive height difference.
[0011] In one of the embodiments, a positioning portion is protruded from the bottom of the pot body, the positioning portion is inserted into the through hole, and the height of the positioning portion is not greater than the height difference between the top surface of the protrusion and the plate surface of the heating plate.
[0012] With such a configuration, by inserting the positioning portion into the through hole, the pot body and the base assembly are accurately positioned, making it easier for the user to assemble the pot body. This also prevents the pot body from sliding radially relative to the base assembly during use, thereby improving the stability of the pot body on the base assembly.
[0013] In one of the embodiments, the top surface of the protrusion is higher than the plate surface of the heating plate, the bottom of the pot body is recessed to provide a positioning groove, and the protrusion passes through the through hole and is inserted into the positioning groove.
[0014] With such a configuration, the protrusion is inserted into the positioning groove, so that the pot body and the base assembly are accurately positioned, which makes it easier for users to assemble the pot body. At the same time, it also prevents the pot body from sliding radially relative to the base assembly during use, thereby improving the stability of the pot body on the base assembly.
[0015] In one embodiment, the height of the protrusion is not greater than the sum of the thickness of the heating plate and the depth of the positioning groove.
[0016] Such an arrangement ensures the stability and reliability of the cooperation between the protrusion and the positioning groove, while preventing the protrusion from lifting the pot body due to the protrusion being too high.
[0017] In one embodiment, the height difference between the top surface of the protrusion and the bottom surface of the protrusion is 2 mm to 25 mm.
[0018] Such an arrangement ensures the stability and reliability of the cooperation between the protrusion and the through hole, while preventing the overall thickness of the base assembly from being too large due to excessive height difference.
[0019] In one embodiment, the cross-sectional area of the protrusion gradually increases along the direction from the top surface of the protrusion toward the bottom surface of the protrusion.
[0020] With such a configuration, the outer side surface of the protrusion can play a guiding role. When the user installs the heating plate on the cover body, even if the protrusion and the through hole are not completely aligned, the outer side surface of the protrusion can be abutted against the inner side surface of the through hole, so that the heating plate moves relative to the cover body, and the protrusion gradually aligns with the through hole, which is convenient for the user to position and install the heating plate and the cover body.
[0021] In one embodiment, the top of the protrusion is chamfered.
[0022] With such a configuration, the chamfer can play a guiding role, making it easier for the user to position the protrusion and the through hole, and can also prevent the sharp edges on the top of the protrusion from scratching the user's hands or damaging the heating plate and the pot body.
[0023] In one of the embodiments, a chamfer is provided on an edge of the through hole on a side facing the cover body.
[0024] With such arrangement, the chamfer can play a guiding role, making it easier for the user to position the protrusions and through holes, and can also prevent sharp edges at the bottom of the heating plate from scratching the user's hands or damaging the cover.

[0032] 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.
[0033] In cooking utensils such as electric hot pots that heat the pot body through an electric heating plate, the electric heating plate is usually cast by centrifugal casting, and a through hole is formed in the center of the electric heating plate. Due to the existence of the through hole, some impurities or water can easily enter the base assembly through the through hole, which can easily cause damage to some components in the base assembly. Therefore, currently, the through hole is mainly blocked by a hardware cover plate, and the cover plate is fixed to the electric heating plate by screws, but this method has many parts and a complicated assembly process, which will also increase costs.
[0034] In order to solve the above problems, Figures 1 to 4 As shown, the utility model provides a cooking utensil, which can prevent impurities or water from entering the base assembly through the through hole, has fewer parts, is easy to assemble, and has a low cost.
[0035] like Figure 1 to Figure 2 As shown, specifically, the cooking utensil includes a base assembly 10 and a pot body 20, the base assembly 10 includes a shell 11, a cover body 12 and a heating plate 13, the cover body 12 is located below the heating plate 13, and the heating plate 13 is arranged on the cover body 12; wherein, the heating plate 13 has a through hole 131, and a protrusion 121 is integrally protruded on the cover body 12, and the protrusion 121 is inserted into and blocks the through hole 131.
[0036] In the cooking utensil provided by the embodiment of the utility model, when the heating plate 13 is installed on the cover body 12, the through hole 131 is blocked by the protrusion 121, so that during use, impurities or water above the heating plate 13 will not enter the base assembly 10 through the through hole 131, thereby avoiding damage to the components in the base assembly 10; because the protrusion 121 is integrally arranged on the cover body 12, additional parts such as cover plates and screws can be omitted, the number of parts can be reduced, and the assembly steps of the base assembly 10 can also be simplified to reduce costs.
[0037] Furthermore, by inserting the protrusion 121 into the through hole 131 , the heating plate 13 and the cover body 12 can be accurately positioned, further facilitating assembly by the user.
[0038] like Figure 2As shown, the heating plate 13 is used to support the pot body 20 and heat the pot body 20, and the cover body 12 can be a reflective cover, and is used to reflect the heat radiated downward by the heating plate 13 toward the pot body 20 to reduce heat loss, and also reduce the impact of the heating plate 13 on the lower components. The cover body 12 can be fixed to the housing 11 by means of buckles, screws, etc.
[0039] like Figures 2 to 3 As shown, in one embodiment, the top surface of the protrusion 121 is lower than the surface of the heating plate 13. The top surface of the protrusion 121 and the inner side surface of the through hole 131 form a groove, and a small amount of impurities or water can be accumulated in the groove to prevent the impurities from remaining on the surface of the heating plate 13 and pushing the pot body 20 upward, ensuring that the bottom wall of the pot body 20 can fit the surface of the heating plate 13, and the pot body 20 will not shake relative to the heating plate 13, thereby ensuring the heat transfer effect between the pot body 20 and the heating plate 13. In addition, the top surface of the protrusion 121 is lower than the surface of the heating plate 13, which can also reduce the precision requirements for the processing dimensions of the heating plate 13 and the cover body 12, ensuring that the protrusion 121 does not affect the normal placement of the pot body 20.
[0040] like Figure 3 As shown, specifically, the top surface of the protrusion 121 is lower than the surface of the heating plate 13, and the height difference H1 between the two satisfies 1mm to 20mm. Among them, the height difference H1 can be any value between 1mm and 20mm, such as 1mm, 2mm, 3mm, 4mm...19mm, 20mm, etc. The height difference H1≥1mm ensures that there is enough space to accommodate impurities and water, so that the bottom wall of the pot body 20 can always fit with the surface of the heating plate 13. The height difference H1≤20mm makes it easy for the user to clean up when a small amount of impurities or water enters the groove; at the same time, it also avoids the height difference H1 being too large, which causes the overall thickness of the cover body 12 and the heating plate 13 to be too large, and avoids occupying too much storage space due to the excessive size of the base assembly 10.
[0041] like Figure 3As shown, a positioning portion 21 is convexly provided at the bottom of the pot body 20, and the positioning portion 21 is inserted into the through hole 131, and the height of the positioning portion 21 is not greater than the height difference between the top surface of the protrusion 121 and the plate surface of the heating plate 13. By inserting the positioning portion 21 into the through hole 131, the pot body 20 and the base assembly 10 are accurately positioned, which is convenient for users to assemble the pot body 20, and at the same time, it is also prevented that the pot body 20 slides radially relative to the base assembly 10 during use, thereby improving the stability of the pot body 20 on the base assembly 10. The height of the positioning portion 21 needs to be less than or equal to the height difference H1, so that the bottom wall of the pot body 20 can fit with the plate surface of the heating plate 13, and the pot body 20 is prevented from shaking relative to the base assembly 10, thereby ensuring the heat transfer effect between the pot body 20 and the heating plate 13. Furthermore, the positioning portion 21 and the through hole 131 are not easily deformed even after long-term use, thereby ensuring that the bottom wall of the pot body 20 can always fit the plate surface of the heating plate 13 to ensure the stability of the pot body 20 on the base assembly 10.
[0042] Among them, the edge of the through hole 131 on the side facing the positioning portion 21 can be chamfered, and the bottom of the positioning portion 21 can also be chamfered. The inner diameter of the chamfered part is larger, so that it can play a guiding role, so that the user can position the positioning portion 21 and the through hole 131.
[0043] In another embodiment, the top surface of the protrusion 121 is higher than the plate surface of the heating plate 13, and the bottom of the pot body 20 is recessed with a positioning groove (not shown), and the protrusion 121 is inserted into the positioning groove through the through hole 131. By inserting the protrusion 121 into the positioning groove, the pot body 20 and the base assembly 10 are accurately positioned, which is convenient for users to assemble the pot body 20, and also prevents the pot body 20 from sliding radially relative to the base assembly 10 during use, thereby improving the stability of the pot body 20 on the base assembly 10.
[0044] The edge of the positioning groove on the side facing the heating plate 13 may be chamfered, and the inner diameter of the chamfered portion is larger, so as to play a guiding role, so that the user can position the protrusion 121 and the positioning groove easily.
[0045] Specifically, the height of the protrusion 121 is not greater than the sum of the thickness of the heating plate 13 and the depth of the positioning groove. The top surface is higher than the plate surface of the heating plate 13, and the height of the protrusion 121 above the plate surface of the heating plate 13 is less than or equal to the depth of the positioning groove, so as to ensure the stability and reliability of the cooperation between the protrusion 121 and the positioning groove, and prevent the pot body 20 from radially sliding relative to the heating plate 13 and the cover body 12, and prevent the protrusion 121 from lifting the pot body 20, causing the bottom wall of the pot body 20 and the heating plate 13 to not fit together.
[0046] In other words, the height difference between the protrusion 121 and the surface of the heating plate 13 is set to H2, and the depth of the positioning groove needs to be less than or equal to the height difference H2, so that the bottom wall of the pot body 20 can fit with the surface of the heating plate 13 to prevent the pot body 20 from shaking relative to the base assembly 10, thereby ensuring the heat transfer effect between the pot body 20 and the heating plate 13.
[0047] Of course, in another embodiment, the top surface of the protrusion 121 can also be flush with the surface of the heating plate 13. In this case, the bottom of the pot body 20 can be a plane or a recessed bottom with a positioning groove, so that the pot body 20 can be stably placed on the plane formed by the top surface of the protrusion 121 and the surface of the heating plate 13.
[0048] like Figure 3 As shown, the height difference H3 between the top surface of the protrusion 121 and the bottom surface of the protrusion 121 is 2mm to 25mm. The height difference H3 can be any value between 2mm and 25mm, such as 2mm, 3mm, 4mm, 5mm...24mm, 25mm, etc. The height difference H3≥2mm ensures the stability and reliability of the cooperation between the protrusion 121 and the through hole 131, avoids radial sliding of the heating plate 13 relative to the cover body 12, and thus ensures the stability of the pot body 20 on the base assembly 10. The height difference H3≤25mm avoids excessive height difference H3 that causes the overall thickness of the base assembly 10 to be too large, and avoids occupying too much storage space.
[0049] In the illustrated embodiment, since the through hole 131 is formed in the center of the heating plate 13 during the centrifugal casting process, the cross section of the through hole 131 is generally circular, and the cross section of the protrusion 121, the positioning portion 21 or the positioning groove can be correspondingly set to be circular. The through hole 131, the protrusion 121 positioning portion 21 or the positioning groove has no restrictions on the installation direction and angle of the pot body 20, the heating plate 13 and the cover body 12, and the user can install the pot body 20 and the heating plate 13 in any direction.
[0050] Of course, in other embodiments, the cross-section of the through hole 131, the protrusion 121, the positioning portion 21 or the positioning groove can also be set to a regular or irregular shape such as an ellipse, a triangle, a quadrilateral, etc. as needed. As long as it is ensured that when the protrusion 121 is inserted into the through hole 131 and the positioning groove, or when the protrusion 121 and the positioning portion 21 are inserted into the through hole 131, the pot body 20, the heating plate 13 and the cover body 12 do not shake relative to each other, the embodiments of the utility model are not specifically limited here.
[0051] Furthermore, the outer side surface of the protrusion 121 can be a curved surface, a flat surface or an irregular curved surface, and the curved surface and the flat surface can facilitate the production and processing of the protrusion 121. When the outer side surface of the protrusion 121 is a curved surface, the vertical cross section of the outer side surface is an arc; when the outer side surface of the protrusion 121 is a flat surface, the vertical cross section of the outer side surface is a straight line.
[0052] like Figure 3 to Figure 4 As shown, along the direction from the top surface of the protrusion 121 to the bottom surface of the protrusion 121, the cross-sectional area of the protrusion 121 gradually increases. When the cross section of the protrusion 121 is circular, and the outer side surface of the protrusion 121 is a plane, the protrusion 121 is in a truncated cone shape, and the cross-sectional area of the end of the protrusion 121 away from the pot body 20 is larger than the cross-sectional area of the end of the protrusion 121 close to the pot body 20. In this way, the outer side surface of the protrusion 121 can play a guiding role. When the user installs the heating plate 13 on the cover body 12, even if the protrusion 121 and the through hole 131 are not completely aligned, the outer side surface of the protrusion 121 can be abutted against the inner side surface of the through hole 131, so that the heating plate 13 moves relative to the cover body 12, and the protrusion 121 gradually aligns with the through hole 131, so that the user can easily position and install the heating plate 13 and the cover body 12.
[0053] like Figure 3 to Figure 4 As shown, in the illustrated embodiment, the top of the protrusion 121 is provided with a chamfer, and the edge of the through hole 131 on the side facing the cover body 12 is also provided with a chamfer. The inner diameter of the chamfered portion is relatively large, so it can also play a guiding role, further facilitating the user to position the protrusion 121 and the through hole 131. In addition, the chamfer can also prevent the presence of sharp edges on the top of the protrusion 121 or the bottom of the heating plate 13 from scratching the user's hands or damaging the heating plate 13, the cover body 12 and the pot body 20. Among them, the chamfer can be a bevel or a rounded corner. Of course, in other embodiments, only the top of the protrusion 121 may be provided with a chamfer, or only the edge of the through hole 131 on the side facing the cover body 12 may be provided with a chamfer.
[0054] 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 20 can be detachably mounted with the base assembly 10, and the embodiment of the utility model does not impose any specific limitation thereto.
[0055] 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.
[0056] 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.
