AI Technical Summary

Technical Problem

The heat-conducting ducts of the existing heat-conducting inner liner are prone to rupture under pressure at high temperatures, causing fragments to fly and posing a safety hazard.

Method used

A pressure relief section is provided on the polygonal structure of the heat-conducting pulsator. The pressure-bearing strength of the pressure relief section is lower than that of other heat-conducting pulsators. When the internal pressure exceeds the pressure-bearing strength, the pressure relief section ruptures to release pressure and safely releases the pressure through the pressure relief channel, avoiding fragments from splashing.

Benefits of technology

It effectively avoids the rupture of the heat conduction tube wall and the splashing of fragments, improving the safety of cooking appliances, and reduces pressure relief noise through the sound-dampening component.

Abstract

This invention discloses a cooking container, comprising a cylindrical container wall with hollow, protruding heat-conducting ducts on its outer surface. The heat-conducting ducts form several polygonal structures filled with a heat-conducting medium. At least one polygonal structure has a pressure-relief section. The pressure-bearing capacity of the pressure-relief section is lower than that of the other heat-conducting ducts. When the pressure inside the heat-conducting duct exceeds the pressure-bearing capacity of the pressure-relief section, the pressure-relief section is destroyed, releasing pressure. A cooking utensil is also disclosed, comprising a utensil body and a lid. The utensil body has a cavity containing the aforementioned cooking container. This invention solves the problem of heat-conducting duct walls rupturing into splattering fragments under pressure. When the pressure-relief section breaks, a rupture point is formed instead of localized fragments, reducing damage to the utensil body and other components, and improving user safety.
