Description

Pot body assembly and cooking utensil with same

Technical Field

The utility model relates to a small household appliances technical field particularly, relates to a pot body subassembly and have its cooking utensil.

Background

In the related art, the electric pressure cooker includes a cooker body and a cooker cover, the cooker body includes a middle plate assembly, a heat-insulating cover and an inner cooker, and the middle plate assembly is matched with the heat-insulating cover.

Usually, medium plate subassembly and heat preservation cover are fixed through two kinds of modes, and one kind is fixed by the mode that adopts the screw, but this kind of mode operation difficulty labour cost is high, has not only increased holistic assembly complexity but also damaged the heat preservation cover easily, makes the heat preservation cover fixed unstably. The other type is that the elastic buckle position through the middle plate is fixed with the middle plate and carries out axial spacing through the support ring structure, and middle plate elasticity is buckled and is the plastic part, has the problem of detaining absolutely and needs to increase solitary positioning element, and is with high costs, assembles complicacy.

Above-mentioned two kinds of fixed modes all make the cover that keeps warm after the installation keeps warm and cover difficult taking out to probably damage the medium plate subassembly when taking out the cover that keeps warm, bring inconvenience for subsequent use and maintenance.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a pot body assembly and cooking utensil with same to solve the problem that the heat preservation cover in the correlation technique is difficult to take out.

In order to achieve the above object, according to an aspect of the present invention, there is provided a pot body assembly, comprising: an outer pot; the middle plate structure is arranged at the top of the outer pot and comprises a middle plate body and a first stopping convex part which is arranged on the inner wall of the middle plate body and protrudes inwards, and the first stopping convex part is provided with a first stopping surface; the heat preservation cover comprises a heat preservation cover body and an elastic convex part arranged on the outer wall of the heat preservation cover body, the heat preservation cover is arranged in the middle plate structure, the first stop convex part is in butt fit with the elastic convex part, the elastic convex part is provided with a matching surface in contact with the first stop surface, and the first stop surface comprises a first arc-shaped surface or a first inclined surface so that the heat preservation cover is detachably connected with the middle plate structure.
