Why is it very hot outside the rice cooker? It's hot in a few minutes. What's wrong with it?
One possibility is that the installation is incorrect, causing a large amount of heat from the heating plate to pass through the connector to the housing.
First, the cooker is not contacted with the heating plate, which leads to a large amount of heat distributed to the small space between the outer shell of the rice cooker and the heating plate, causing the outer shell to generate heat.
Put a little water in the pot, and then press the pan side to shake, and if feel the pot is very smooth, may be the second reason. If it is not smooth, it may be the first reason.Another possibility (but rare) is that when you cook, the heat preservation circuit is connected, and your warm heat is distributed to the shell.
