Oval inner pot, electric pressure cooker and combination method of pot edge of inner pot

Abstract

The invention provides an oval inner pot, an electric pressure cooker and a combination method of a pot edge of the inner pot. The oval inner pot comprises a pot body and a pot edge reinforcing plate,wherein the pot body comprises the pot edge, the cross section of the pot body is oval, the pot edge is positioned at the open end of the pot body, and the pot edge extends outwards along the radialdirection of the pot body; the pot edge reinforcing plate is heated to be laminated to the bottom of the pot edge. For the oval inner pot provided by the invention, the pot edge reinforcing plate is designed at the pot edge, so that the thickness of the pot edge is reinforced locally, meanwhile, the interface between the two layers is in a comprehensive metallurgical bonding state formed through heating lamination, so that the combined layer interface has the characteristics of firmness, high tensile strength and good extension property, the problems that a short shaft becomes long, a long shaft becomes short, and the deformation tends to be round during the process that the oval inner pot bears an inside pressure intensity are solved, the oval inner pot can maintain the stability of integral size deformation when bearing load, and good rigidity is achieved; and meanwhile, a plate material becomes thin through the structure, the weight of the oval inner pot is reduced, and the effect of reducing the cost is achieved.

Description

Technical field [0001] The invention relates to the field of cooking appliances, in particular to an elliptical inner pot, an electric pressure cooker and an inner pot rim compound method. Background technique [0002] The inner pot is one of the core parts of the electric pressure cooker to realize the cooking function. Existing inner pots are divided into circular and elliptical shapes in appearance. Because of the symmetry of structural dimensions, the circular inner pot deforms uniformly after being subjected to internal pressure. Due to the asymmetry of the long and short axis of the elliptical pressure cooker, after being subjected to internal pressure, the size of the long axis of the ellipse becomes smaller and shrinks inward; the size of the short axis becomes larger and expands outward. The overall deformation trend tends to be round. Consider the accuracy of shape control after internal load. Traditional methods rely on increasing the thickness of the material to ach...
