Description

Cooking container and cooking appliance using same [ Field of technology ] The invention relates to the field of kitchen appliances, in particular to a cooking container and a cooking appliance adopting the same. [ Background Art ] Along with the popularization of IH rice cooker with high-efficiency heating, consumers have higher requirements on the shape, the material and the function of the rice cooker. In order to improve the cooking effect of rice in the inner container of the rice cooker, manufacturers are researching the process materials of the inner container in a heating mode, wherein in order to improve the heating uniformity of the inner container, the inner container adopting a soaking process and the like are arranged. A soaking liner adopting a soaking process is characterized by adopting a soaking plate process, namely an interlayer is arranged in the liner, a proper amount of heat conducting liquid is filled in the interlayer, vacuumizing and packaging are carried out, so that the inside of the liner achieves a negative pressure effect, when the liner is heated, the inside of the liner is heated, the negative pressure is adopted, so that water can be boiled and gasified at a very low temperature and absorb a large amount of heat, and meanwhile gasified steam can bring the heat to a place with low temperature of the liner at a very high speed, so that the heat can be instantaneously dispersed to each part of the liner. Some soaking inner containers (aluminum) adopt an inflation plate structure, namely two layers of composite aluminum sheets, and graphite pipelines are silk-screened between interlayers, so that the pipelines printed with graphite are not bonded together due to the existence of graphite during high-temperature compounding, and then the parts which are not bonded together are retracted and arched through pressure inflation to form a hollow vascular pipeline structure. Under the condition of negative pressure in the vessel, the heat conducting liquid is gasified and collided rapidly, the pressure in the vessel is higher when the temperature is higher, the internal pressure born by the vessel is larger, and the vessel is of an arch structure (approximate to a circular arc shape) and is uniformly stressed, so that the traditional flat plate type vapor chamber is of a cantilever structure. So the vessel can bear higher steam pressure, the vessel structure can be suitable for heating at higher temperature, and the pressure value of pressure relief is obviously higher than that of the traditional vapor chamber. However, if the pressure in the pipeline is higher than the tensile strength of the pipeline when the temperature of the rice cooker is kept out of control, the pipeline wall can be rapidly increased, but the whole system is uniformly pressurized, and when the pipeline wall is broken and depressurized, local blocky pipeline wall breakage can occur. Because the limiting pressure breaking through the pipe wall is high at this time, when the pipe wall breaks, high-pressure steam can impact broken pipe wall fragments, so that the fragments splash to damage other parts of the rice cooker and the like. [ Invention ] The invention aims to solve the technical problem of overcoming the defects of the prior art and providing a cooking container for preventing the heat conduction vessel wall from being broken into splash fragments under pressure and a cooking appliance adopting the cooking container. In order to solve the technical problems, the invention adopts the following technical scheme: The cooking container comprises a container wall which surrounds into a cylinder, wherein the container wall is provided with a heat conduction vessel which is hollow and protrudes out of the outer surface of the container wall, the heat conduction vessel surrounds into a plurality of polygonal structures, heat conduction medium is filled in the heat conduction vessel, at least one polygonal structure is provided with a pressure relief part, the pressure bearing strength of the pressure relief part is lower than that of other heat conduction vessels, and when the pressure in the heat conduction vessel exceeds the pressure bearing strength of the pressure relief part, the pressure relief part is damaged to release pressure. In the cooking container, at least two heat conducting vessels on the polygonal structure are intersected to form the pressure relief part, and other heat conducting vessels in the polygonal structure are connected by using fillets. In the cooking container, the polygonal structure is at least a quadrilateral structure, at least two pressure relief portions are arranged in the polygonal structure, and a round angle is arranged between every two adjacent pressure relief portions. In the cooking container, in the same polygonal structure, the number of the pressure relief portions is smaller than the number of the rounded corners. In the cooking container, the wall thickness of the
