Cooking appliance

This invention describes a cooking appliance that can not only cook food but also keep it warm or even cool it for storage. It achieves this by using a special electronic component called a Peltier unit, which can either absorb heat from the cooking chamber to cool it down or release heat into it to warm it up, simply by reversing an electrical current. The claims focus on a specific setup where the Peltier unit's metal parts are connected to the chamber's interior and exterior.
