Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices, systems, apparatuses, and methods consistent with aspects of the present application.

Fig. 1 is a cross-sectional view of a pot body of a cooking appliance according to an embodiment of the present application, the pot body including an outer shell (not shown), a heat-insulating cover 1, an inner pot 2, and a heating device 3. The heat-insulating cover 1 is located in a housing (not shown), and includes a bottom wall 11, a side wall 12, and a cavity 13 surrounded by the bottom wall 11 and the side wall 12. The inner pot 2 is arranged in the cavity 13 of the heat-insulating cover 1, and the heating device 3 is positioned between the bottom of the inner pot 2 and the bottom of the heat-insulating cover 1 and used for heating the inner pot 2. This application cooking utensil is electric pressure cooker, during the culinary art, produces high-pressure gas in the interior pot 2, and interior pot 2 supports downwards to press heating device 3, and heating device 3 is with pressure transmission to heat preservation cover 1, and heat preservation cover 1 plays the effect that keeps warm and resistance to compression.

The top of the side wall 12 of the heat preservation cover 1 is provided with a ring of flanging 14 extending outwards, and when the heat preservation cover 1 is placed in the shell, the flanging 14 is positioned on the upper surface of the shell. The pot body also comprises a support ring 4, the support ring 4 is sleeved outside the heat preservation cover 1, is positioned between the shell (not shown) and the flanging 14, and supports the flanging 14 upwards. The flange 14 includes a plurality of outwardly protruding pot teeth 15, and a plurality of pot cover teeth are provided on a pot cover (not shown) of the cooking appliance, and when the pot cover is rotated to a closed position, the pot cover teeth are located right under the pot body teeth 15 and the support ring 4, and are engaged with the pot body teeth 15 and the support ring 4, so that the pot cover (not shown) and the pot body are maintained in a closed state.

Referring to fig. 2 and 3, the top surface 151 of the pot teeth 15 is integrally formed with a plurality of ribs 16. The provision of the ribs 16 improves the overall strength of the flange 14. When the cooking utensil is subjected to a destructive pressure test, the inner pot 2 is in a closed state, water is injected into the inner pot 2 to evacuate air, then the pressure is increased, and the inner pot 2 applies downward pressure to the heat-insulating cover 1 along with the increase of the pressure in the inner pot 2. The convex rib 16 can buffer part of pressure applied on the pot body teeth 15, reduce the upward deformation degree of the pot body teeth 15, avoid the influence on the sealing performance of the inner pot 2, achieve the requirement required by the test and enable the cooking utensil to pass the destructive pressure test.

The ribs 16 are stamped and formed directly on the insulating cover 1, are simple to manufacture and can be stamped and formed before the side walls 12 are stretched. In the present embodiment, the rib 16 extends in the radial direction of the heat retaining cover 1, but the rib 16 may alternatively extend in other directions. The height of the convex rib 16 is consistent with the thickness of the plate of the heat preservation cover 1. The thickness of the plate of the heat preservation cover 1 is 1mm, the height of the convex rib 16 is 1mm, and the convex rib 16 is directly formed by punching the plate without other processing modes. Wherein, the width of the convex rib 16 is 2mm-5mm, and the length is 5-10mm, which is convenient for punch forming.

The pot body teeth 15 are provided with side edges 152 extending downwards from the outer edges thereof, the inner edges of the top surfaces 151 of the pot body teeth 15 are provided with first arc-shaped surfaces 153 connected with the side walls 12, and the outer edges of the top surfaces 151 are provided with second arc-shaped surfaces 154 connected with the side edges 152. The top surface 151 is provided with a horizontal surface (not shown) between the first arc-shaped surface 153 and the second arc-shaped surface 154, and the length of the rib 16 does not exceed the radial length of the horizontal surface (not shown). In the present embodiment, the rib 16 extends radially from the first arc-shaped surface 153 to the second arc-shaped surface 154, that is, the rib 16 is disposed on the top surface 151 of the pot tooth 15 as long as possible.

Referring to fig. 4, a chamfer 161 is arranged at the joint between the rib 16 and the top surface 151 of the pot teeth 15, and the radius of the chamfer 161 is 0.2 mm. The provision of chamfer 161 avoids stress concentration problems.
