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 certain aspects of the present application, as detailed in the appended claims.

Referring to fig. 1 and 2, the cooking device of the present application includes a pot cover 100 and a pot body 200, where the pot body 200 includes an inner pot 1, a heat-insulating cover 7 and an outer shell 8, the inner pot 1 is accommodated in the heat-insulating cover 7, and the heat-insulating cover 7 is located in the outer shell 8. A cooking cavity is formed between the inner pot 1 and the pot cover 100, and a pot tooth structure which is mutually buckled is arranged between the pot cover 100 and the heat-insulating cover 7.

This cooking utensil is still including being located 1 bottom of pot and the coil panel subassembly that keeps warm and cover 7 bottoms in, the coil panel subassembly is located between 1 bottom of pot and this heat preservation cover 7 bottoms in this for 1 heats pot in this. The cooking utensil also comprises a supporting seat 2, and the supporting seat 2 is also positioned between the bottom of the inner pot 1 and the bottom of the heat-preservation cover 7. The cooking utensil is an electric pressure cooker in the embodiment, the electric pressure cooker can move the inner pot 1 downwards along with the increase of the pressure in the inner pot 1 in the cooking process, and the supporting seat 2 is used for supporting the inner pot 1.

Referring to fig. 3 to 6, the bottom of the supporting base 2 is supported on the bottom wall of the heat-insulating cover 7, and the top of the supporting base is upward supporting the inner pot 1. This supporting seat 2 wholly is cyclic annular, includes the diapire and the lateral wall that upwards extends from the diapire, the center department of diapire is hollow out construction, forms mounting hole 20 for hold coil disc subassembly.

The pressure of the gas in the cooker pot applied to the inner pot 1 is transmitted to the heat-insulating cover 7 through the supporting base 2. The heat-insulating cover 7 is made of metal, so that the heat-insulating cover can bear large pressure. The coil panel assembly does not need to play a supporting role, so PPS plastic does not need to be used, and common heat-resistant plastic is used. This supporting seat 2 provides the supporting role, because the design of mounting hole 20 makes this supporting seat 2 be hollow out construction, compares the coil panel subassembly that is made by PPS plastic material and supports, can practice thrift manufacturing cost. The supporting base 2 can be made of general PBT (Polybutylene terephthalate) plastic material so as to reduce the cost.

In the present embodiment, the coil panel assembly includes a coil panel cover 4, a coil 5 and a coil panel holder 6, and the coil panel cover 4 and the coil panel holder 6 are separately molded and then assembled with each other. Referring to fig. 6, a gap a is provided between the top surface of the coil cover 4 and the bottom surface of the inner pot 1, and the two are kept out of contact, so that the inner pot 1 is supported by the support base 2. The coil base 6 is provided with a plurality of positioning parts (not numbered), and the coil 5 is wound on the top surface of the coil base 6 one turn and fixed by the plurality of positioning parts.

Referring to fig. 4 to 5, and referring to fig. 2, the support base 2 is provided with a ring of steps 21 on the inner wall of the mounting hole 20. After the coil disk seat 6 and the coil 5 are placed below the mounting hole 20 of the support base 2 from bottom to top, the coil disk cover 4 is assembled to the support base 2 from top to bottom, the coil disk cover 4 is supported by the step 21, and the coil disk cover 4 is positioned above the mounting hole 20 and covers the coil 5. And the coil disk cover 4 and the coil disk seat 6 are locked together by screws.
