[0031] First embodiment:
[0032] The embodiment discloses a heating seat.
[0033] Figure 3 It is the internal structure schematic view of the utility model kitchen utensil. As shown in Figure 3 , the heating seat includes a shell 1 and an inner pot 2.
[0034] Figure 4 It is Figure 3 The enlarged view at B. As shown in Figure 3 And Figure 4 The shell 1 is a hollow structure with an opening facing upwards. The shell 1 includes a first flange 11 and an annular groove body 12. The first flange 11 is connected to the upper end of the shell 1 at the first end, and extends towards the inner side of the shell 1 at the second end. The annular groove body 12 is connected to the second end of the first flange 11 at the first end. Illustratively, the shell 1 is a cylindrical body with an open upper end and a closed lower end. The cross section of the first flange 11 is a downward-opening circular arc with a central angle of 180°, and the tangent line at the first end is parallel to the vertical plane. The annular groove body 12 includes a first cylindrical body 122 and a first annular edge 121. The first cylindrical body 122 is vertically arranged and connected to the second end of the first flange 11 at the upper end. The first annular edge 121 is horizontally arranged and connected to the lower end of the first cylindrical body 122 at the first end.
[0035] As shown in Figure 3 And Figure 4As shown, the inner pot 2 is a hollow structure with its opening facing upwards, housed within the outer shell 1. The inner pot 2 includes a second flange 21, which convex upwards. The second end of the second flange 21 is connected to the upper end of the inner pot 2, and the first end extends outwards from the inner pot 2 and overlaps within the annular groove 12. For example, the lower end of the inner pot 2 is screwed to the bottom inner side of the outer shell 1. The second flange 21 includes a vertically arranged second cylindrical body 211 and a third cylindrical body 213, and a horizontally arranged second annular edge 212. The third cylindrical body 213 is positioned outside the second cylindrical body 211. The lower end of the second cylindrical body 211 is connected to the upper end of the inner pot 2, and the lower end of the third cylindrical body 213 overlaps with the first annular edge 121. The first end of the second annular edge 212 is connected to the upper end of the third cylindrical body 213, and the second end is connected to the upper end of the second cylindrical body 211. The horizontally arranged second annular edge 212 can stably support the cookware 3.
[0036] like Figure 4 As shown, the top of the second flange 21 is not higher than the top of the first flange 11. Preferably, the upper end of the second ring edge 212 is flush with the upper end of the first flange 11, so that the heating seat can extend outward when the cookware 3 is placed inside the inner pot 2.
[0037] Preferably, the length of the second ring edge 212 is 30-50mm. An appropriate length can extend the heat transfer and improve the heat dissipation effect. If it is too long, it will increase the cost of the product.
[0038] Preferably, the connection between the first cylinder 122 and the first ring edge 121 is chamfered, the connection between the second cylinder 211 and the second ring edge 212 is chamfered, and the connection between the third cylinder 213 and the second ring edge 212 is chamfered, which improves the aesthetics and safety of the kitchenware.
[0039] Furthermore, several notches (not shown in the figure) are spaced apart on the first annular edge 121 corresponding to the third cylindrical body 213. Alternatively, several notches (not shown in the figure) are spaced apart on the third cylindrical body 213 corresponding to the first annular edge 121. Alternatively, several notches are spaced apart on both the first annular edge 121 and the third cylindrical body 213. These notches allow the lower end of the third cylindrical body 213 to make spaced contact with the upper surface of the first annular edge 121, reducing the contact area between the third cylindrical body 213 and the first annular edge 121, preventing excessive heat transfer from the third cylindrical body 213 to the annular groove 12 and the first flange 11, further improving consumer safety.
[0040] like Figure 4 As shown, furthermore, there is a radial gap between the first cylindrical body 122 and the third cylindrical body 213. Specifically, this radial gap is 0.1 to 2 mm, which prevents the first cylindrical body 122 from contacting the third cylindrical body 213 and causing the outer casing 1 to overheat, thereby further improving consumer safety.
[0041] In the embodiment, the second flange 21 is overlapped on the annular groove body 12, and the top of the second flange 21 is not higher than the top of the first flange 11, so that the second flange 21 is hidden in the annular groove body 12, and the outer edge 311 of the pot 3 is supported on the second flange 21, and the consumer is not easy to touch the hidden second flange 21 when taking or putting down the pot 3 from the side, the structure is simple, and the safety of the heating seat is improved.
[0042] Second embodiment:
[0043] The embodiment discloses a kitchen utensil.
[0044] In the embodiment, the kitchen utensil is an electric stew pot. Those skilled in the art can know that the technical solution of the present disclosure can also be applied to other kinds of kitchen utensils that need to be heated, such as an electric fryer, an electric boiling pot and an electric rice cooker.
[0045] Figure 5 It is a perspective view of the kitchen utensil of the present application. Figures 3 to 5 As shown in the figure, the kitchen utensil comprises a heating seat and a pot 3. The heating seat is as described above. The pot 3 is placed in the inner pot 2 and is overlapped on the second flange 21 on the outside. Exemplarily, the pot 3 comprises an inner container 31 and a cover 32. The inner container 31 is a hollow structure with an opening facing upwards, is made of ceramic material, has an outer edge 311 on the outside upper end, and the outer edge 311 is overlapped on the second flange 21 on the lower end. The cover 32 is clamped in the outer edge 311. Specifically, the outer edge 311 is in a stepped shape, and the lower end of the cover 32 is clamped into the recess formed by the inner side of the step.
[0046] As shown in the figure, Figure 3 Further, the heating seat comprises a heating element 4, and the heating element 4 is arranged at least one of the outside and the lower end of the inner pot 2. Exemplarily, the heating element 4 is an electric heating tube or an electric heating wire. The inner pot 2 is made of metal material, so that the heating element 4 can transfer heat to the inner pot 2 by heat conduction.
[0047] In the embodiment, the pot 3 is placed in the inner pot 2 of the heating seat, the outer edge 311 of the pot 3 is overlapped on the second flange 21, it is convenient to take and put, and since the outer edge 311 only contacts the upper end of the second flange 21, the contact area of the outer edge 311 with the inner pot 2 is small, the temperature of the outer edge 311 is low, and the safety of the consumer is high. At the same time, since the lower end of the third cylinder 213 is overlapped on the first ring edge 121, the contact area of the inner pot 2 with the outer shell 1 is small, the temperature of the outer shell is low, the safety of the consumer is improved, and the service life of the power cord is prolonged.
[0048] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
[0049] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
