[0001] The utility model relates to the technical field of kitchen appliances, in particular to an inner pot and a cooking utensil. Background Art
[0002] Cooking appliances such as steam ovens have become a necessity in household life. Figure 1 to Figure 3 As shown, the cooking utensil 1000 generally includes an inner pot 100 and a front panel 300, wherein the inner pot 100 includes an inner pot body 10 and a flange 20, wherein the inner pot body 10 includes an inner pot left enclosure 12, an inner pot lower enclosure 13, an inner pot right enclosure 14, an inner pot upper enclosure 15 and a back panel 16, the inner pot left enclosure 12, the inner pot lower enclosure 13, the inner pot right enclosure 14 and the inner pot upper enclosure 15 are sequentially connected end to end, the inner pot left enclosure 12, the inner pot lower enclosure 13, the inner pot right enclosure 14 and the inner pot upper enclosure 15 jointly form an inner pot opening 11 arranged along the front and back and an inner pot rear opening, the back panel 16 is sealed at the inner pot rear opening, and the front panel 300 is arranged at the inner pot opening 11 and is used to install a door body, etc.
[0003] like Figure 1 to Figure 3 As shown, the inner liner 100 further includes a flange 20. Usually, the front end of the inner liner 100 is flattened outward to form an outward-turned flange 20. Figure 3 As shown, the flange 20 includes a corner arc section 26, a parallel section 23 and a connecting section 24. The edge of the liner opening 11, the corner arc section 26, the parallel section 23 and the connecting section 24 are sequentially connected. The parallel section 23 is parallel and spaced apart on the outer side of the liner enclosure. The connecting section 24 is vertically arranged with the parallel section 23. The corner arc section 26 is an outwardly convex arc section. The front panel 300 includes a front panel body 320 and a folded edge 310. The front panel body 320 is provided with a front panel opening 321. The folded edge 310 includes a vertical section 311 and a horizontal section 312. The edge of the front panel opening 321, the vertical section 311 and the horizontal section 312 are sequentially connected. Figure 3 As shown, the flange 20 is inserted into the inner edge of the horizontal section 312, and the horizontal section 312 and the connecting section 24 are opposite and fixed to each other, thereby achieving a stable connection between the liner 100 and the front panel 300, wherein the horizontal section 312 and the connecting section 24 can be fixed by welding, bolting, clamping, etc.
[0004] At present, the materials of the inner pot 100 of the cooking utensils 1000 on the market are mainly stainless steel and enamel. Compared with stainless steel, enamel has obvious advantages in cleaning and heat preservation. Figure 3As shown, since the single-layer thickness of the flange 20 is relatively small, in order to achieve stable support for the connecting section 24 and the front panel 300 on the connecting section 24, the distance between the connecting section 24 and the upper liner panel 15 in the vertical direction is relatively small, and the double-layer thickness flange 20 can provide stable support for the front panel 300, preventing the front panel 300 from deforming or shaking in the arrangement direction of the connecting section 24 and the upper liner panel 15. Therefore, Figure 3 As shown, since the single-layer thickness of the flange 20 is small and the spacing between the parallel section 23 and the inner pot enclosure along the arrangement direction is small, the corner arc section 26 is small in size, and the corner arc section 26 is not easy to be porcelain-attached, resulting in the enamel inner pot 100 being prone to porcelain bursting at the corner arc section 26. After encountering steam or condensed water, rust will occur at the location where the porcelain burst occurs, and rust will occur in the cooking utensil 1000.
[0005] Therefore, it is urgent to design a new inner pot and cooking utensil to improve the above problems. Utility Model Content

[0050] The cooking appliance 1000 provided in the embodiment of the present disclosure may be an oven, a steamer, a steam oven, a microwave oven, an integrated stove, a steaming and baking all-in-one machine, etc. The embodiment of the present disclosure takes a steam oven as an example for explanation. The steam oven can steam and cook food alone, and can also bake food alone. Users can adaptively select the steaming function or baking function of the steam oven according to their own cooking needs. The steam oven has many functions, which is convenient for users to use in a variety of ways. The steam oven has become a necessity for family life.
[0051] like Figure 1 to Figure 3As shown, the steam oven generally includes an inner tank 100 and a front panel 300, wherein the inner tank 100 includes an inner tank body 10 and a flange 20, wherein the inner tank body 10 includes an inner tank left panel 12, an inner tank lower panel 13, an inner tank right panel 14, an inner tank upper panel 15 and a back panel 16, the inner tank left panel 12, the inner tank lower panel 13, the inner tank right panel 14 and the inner tank upper panel 15 are sequentially connected end to end, the inner tank left panel 12, the inner tank lower panel 13, the inner tank right panel 14 and the inner tank upper panel 15 jointly form an inner tank opening 11 arranged along the front and back and an inner tank rear opening, the back panel 16 is sealed at the inner tank rear opening, and the front panel 300 is arranged at the inner tank opening 11 and is used to install a door body, etc.
[0052] like Figure 1 to Figure 3 As shown, the inner liner 100 further includes a flange 20. Usually, the front end of the inner liner 100 is flattened outward to form an outward-turned flange 20. Figure 3 As shown, the flange 20 includes a corner arc section 26, a parallel section 23 and a connecting section 24. The edge of the liner opening 11, the corner arc section 26, the parallel section 23 and the connecting section 24 are sequentially connected. The parallel section 23 is parallel and spaced apart on the outer side of the liner enclosure. The connecting section 24 is vertically arranged with the parallel section 23. The corner arc section 26 is an outwardly convex arc section. The front panel 300 includes a front panel body 320 and a folded edge 310. The front panel body 320 is provided with a front panel opening 321. The folded edge 310 includes a vertical section 311 and a horizontal section 312. The edge of the front panel opening 321, the vertical section 311 and the horizontal section 312 are sequentially connected. Figure 3 As shown, the flange 20 is inserted into the inner edge of the horizontal section 312, and the horizontal section 312 and the connecting section 24 are opposite and fixed to each other, so as to achieve a stable connection between the liner 100 and the front panel 300, wherein the horizontal section 312 and the connecting section 24 can be fixed by welding, bolting, clamping, etc. It should be noted that all methods that can achieve a fixed connection between the horizontal section 312 and the connecting section 24 are within the protection scope of the embodiments of the present disclosure.
[0053] At present, the materials of the inner pot of the steam oven on the market are mainly stainless steel and enamel. Compared with stainless steel, enamel has obvious advantages in cleaning and heat preservation. Figure 3 As shown, since the thickness W of a single layer of the flange 20 is generally 0.6 mm to 0.9 mm, the thickness W of a single layer of the flange 20 is relatively small. In order to achieve stable support for the connecting section 24 and the front panel 300 on the connecting section 24, the distance between the connecting section 24 and the liner upper panel 15 along the up-down direction (i.e., the first direction) is relatively small. The double-layer flange 20 with a relatively close distance can provide stable support for the front panel 300, and prevent the front panel 300 from deforming or shaking in the arrangement direction of the connecting section 24 and the liner upper panel 15. Therefore, as Figure 3As shown, the distance between the parallel section 23 and the outer side surface of the upper enclosure 15 of the inner pot is small in the up-down direction, resulting in a small size of the corner arc section 26 in the up-down direction. The corner arc section 26 is not easy to be porcelain-attached, resulting in the enameled inner pot 100 being prone to porcelain bursting at the corner arc section 26. After encountering steam or condensed water, rust will occur at the location where the porcelain burst occurs, and rust will occur in the steam oven.
[0054] In addition, a large degree of plastic deformation occurs at the corner arc segment 26 in a smaller space. The degree of deformation at the corner arc segment 26 is large, and the stress and strain of the material at the corner arc segment 26 are large, which causes the flange 20 to easily break and be damaged at the corner arc segment 26, affecting the normal use of the inner pot 100 and the steam oven.
[0055] To solve the above problems, Figures 4 to 7 As shown, the flange 20 includes an outer convex arc segment 21, an inclined straight line segment 22, a parallel segment 23 and a connecting segment 24. Figure 7 As shown, the edge M of the inner liner opening 11, the convex arc segment 21, the inclined straight line segment 22, the parallel segment 23 and the connecting segment 24 are connected in sequence, the convex arc segment 21 and the inclined straight line segment 22 are connected at the connecting position P, the inner liner body 10 is arranged in parallel on one side of the parallel segment 23, and the connecting position P is located on the other side of the parallel segment 23. The convex arc segment 21 and the inclined straight line segment 22 are not limited to the space occupied by the parallel segment 23 and the inner liner upper enclosure 15 in the up and down directions. The convex arc segment 21 and the inclined straight line segment 22 form a larger "large corner structure". Under the premise that other structures and sizes are the same, the size of the "large corner structure" is relatively Figure 3 The size of the corner arc section 26 is obviously larger, and the "large corner structure" is more likely to be stained with porcelain. The enamel inner pot 100 is not prone to porcelain explosion at the "large corner structure", which avoids rust in the steam oven and ensures the normal use of the inner pot 100 and the steam oven. For example, Figure 7 As shown, the convex arc segment 21 has a curvature center O1, and the liner upper enclosure 15, the convex arc segment 21 and the inclined straight line segment 22 communicate to form an inner cavity, and the curvature center O1 is located in the inner cavity.
[0056] In addition, the plastic deformation of the "large corner structure" is gradual, and the degree of plastic deformation of the "large corner structure" is relatively Figure 3 The corner arc section 26 is more gentle, and the stress and strain of the material at the "large corner structure" are relatively Figure 3 The stress and strain of the material at the corner arc section 26 are small, and the flange 20 is not easy to break or be damaged at the convex arc section 21 and the inclined straight line section 22, thereby ensuring the normal use of the inner pot 100 and the steam oven.
[0057] As an optional embodiment, Figure 7 As shown, the line connecting the center of curvature O1 and the edge M of the inner pot opening 11 is O1M, and the line connecting the center of curvature O1 and the connection position P is O1P, wherein the angle α formed by O1M and O1P is less than 180°, the convex arc segment 21 is a superior arc, the arc length of the convex arc segment 21 is further increased, the size of the convex arc segment 21 is further increased, and the porcelain hanging effect of the convex arc segment 21 is further enhanced. The enamel material inner pot 100 is not prone to porcelain explosion in the convex arc segment 21, avoiding rust problems in the steam oven, and ensuring the normal use of the inner pot 100 and the steam oven. Exemplarily, the angle α can be 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 175°, etc. In other embodiments, the range of the angle α is not limited to the above range, and can also be adjusted according to needs.
[0058] As an optional embodiment, Figure 7 As shown, the inner wall of the inner pot body 10 is tangent to the outer peripheral surface of the convex arc segment 21, and the outer wall surface of the inner pot body 10 is tangent to the inner peripheral surface of the convex arc segment 21. The connection between the inner pot body 10 and the convex arc segment 21 is very stable and smooth, which avoids severe deformation at the connection position between the inner pot body 10 and the convex arc segment 21, and prevents the stress and strain concentration and excessive size at the connection position between the inner pot body 10 and the convex arc segment 21. It also avoids the inner pot 100 from breaking at the connection position between the inner pot body 10 and the convex arc segment 21, and avoids the inner pot 100 from rusting, thereby ensuring the normal use of the inner pot 100 and the steam oven.

The connection between the inclined straight line segment 22 and the convex arc segment 21 is very stable and smooth, which avoids severe deformation at the connection position between the inclined straight line segment 22 and the convex arc segment 21, and prevents the problem of concentrated and excessive stress and strain at the connection position between the inclined straight line segment 22 and the convex arc segment 21. It is avoided that the inner pot 100 is prevented from breaking at the connection position between the inclined straight line segment 22 and the convex arc segment 21, and the inner pot 100 is prevented from rusting, thereby ensuring the normal use of the inner pot 100 and the steam oven.
[0060] As an optional embodiment, Figure 7As shown, a transition fillet 25 is provided at the connection between the inclined straight line segment 22 and the parallel segment 23, and the connection between the inclined straight line segment 22 and the parallel segment 23 is very stable and smooth, which avoids severe deformation at the connection position of the inclined straight line segment 22 and the parallel segment 23, prevents the problem of excessive stress and strain concentration at the connection position of the inclined straight line segment 22 and the parallel segment 23, prevents the inner pot 100 from breaking at the connection position of the inclined straight line segment 22 and the parallel segment 23, and prevents the inner pot 100 from rusting, thereby ensuring the normal use of the inner pot 100 and the steam oven. For example, as Figure 7 As shown, the transition fillet 25 is an arc, the center of the transition fillet 25 is O2, and O2 is outside the inclined straight line segment 22, the parallel segment 23 and the transition fillet 25.
[0061] As an optional embodiment, Figure 7 As shown, from the edge M of the inner pot opening 11 to the connection position P, the radius of curvature of the convex arc segment 21 tends to increase, the arc length of the convex arc segment 21 is further increased, the size of the convex arc segment 21 is further increased, and the porcelain hanging effect of the convex arc segment 21 is further enhanced. The enamel inner pot 100 is not prone to porcelain explosion in the convex arc segment 21, which avoids rust problems in the steam oven and ensures the normal use of the inner pot 100 and the steam oven.
[0062] As an optional embodiment, Figure 7 As shown, the convex arc segment 21 includes at least two circular arc segments connected in sequence, the centers of the at least two circular arc segments are concentrically arranged and coincide with the curvature center O1, and the radius of the inner arc of the at least two circular arc segments gradually increases from the edge M of the inner liner opening 11 to the connection position P, which is convenient for processing the convex arc segment 21. For example, Figure 7 As shown, the convex arc segment 21 includes a first arc segment 211 and a second arc segment 212 connected to each other, the curvature center of the first arc segment 211 and the curvature center of the second arc segment 212 coincide with each other and are O1, the radius of the inner arc of the first arc segment 211 is R1, the radius of the inner arc of the second arc segment 212 is R2, and R1 is smaller than R2. For example, R1 can be 0.7 mm to 2.2 mm, and R2 can be 1.7 mm to 4.2 mm.
[0063] As an optional embodiment, Figure 7 As shown, the convex arc segment 21 includes at least two circular arc segments connected in sequence, the centers of the at least two circular arc segments are concentrically arranged and coincide with the curvature center O1, and the radius of the outer arc of the at least two circular arc segments gradually increases from the edge M of the inner liner opening 11 to the connection position P, which is convenient for processing the convex arc segment 21. For example, Figure 7As shown, the convex arc segment 21 includes a first arc segment 211 and a second arc segment 212 connected to each other, the curvature center of the first arc segment 211 and the curvature center of the second arc segment 212 coincide with each other and are O1, the radius of the outer arc of the first arc segment 211 is R3, the radius of the outer arc of the second arc segment 212 is R4, and R3 is smaller than R4. For example, R3 can be 1.5 mm to 3 mm, and R3 can be 1.7 mm to 5 mm.

Controlling L2 / L1 to 4 to 15 can, on the one hand, prevent the "large corner structure" from exploding, and on the other hand, prevent the "large corner structure" from being too large and affecting the size of the horizontal section 312, thereby ensuring a larger contact area between the horizontal section 312 and the connecting section 24, achieving a stable connection between the horizontal section 312 and the connecting section 24, and ensuring that the flange 20 provides a stable support to the front panel 300.
[0065] As an optional embodiment, Figure 7 As shown, the maximum spacing between the inner circumference of the convex arc segment 21 and the inner tank body 10 in the up and down direction is L2, wherein L2 is 3mm to 10mm. If L2 is controlled within 3mm to 10mm, on the one hand, it can avoid porcelain explosion of the "large corner structure", and on the other hand, it can also avoid the "large corner structure" from being too large and affecting the size of the horizontal section 312, ensuring a larger contact area between the horizontal section 312 and the connecting section 24, achieving a stable connection between the horizontal section 312 and the connecting section 24, and ensuring that the flange 20 firmly supports the front panel 300.

Exemplarily, L2 / W can be 3, 4, 5, 6, 7, 8, etc. In other embodiments, the range of L2 / W is not limited to the above range, and can also be adjusted according to demand.
[0067] As an optional embodiment, Figure 7 As shown, the maximum spacing between the inner circumference of the convex arc segment 21 and the inner tank body 10 in the up-down direction is L2, and the length of the inclined straight line segment 22 is L5, wherein L5 / L2 is 1-2. L5 / L2 is controlled to be 1-2. On the one hand, it can avoid porcelain explosion in the "large corner structure". On the other hand, it can also avoid the "large corner structure" from being too large and affecting the size of the horizontal segment 312, ensuring a larger contact area between the horizontal segment 312 and the connecting segment 24, achieving a stable connection between the horizontal segment 312 and the connecting segment 24, and ensuring that the flange 20 firmly supports the front panel 300. Exemplarily, L5 / L2 can be 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, etc. In other embodiments, the range of L5 / L2 is not limited to the above range, and can also be adjusted according to demand.
