Abstract
A heating cooking apparatus including a body, a steam container, a steam heater, and a heater covering portion. The body has a cooking compartment in which food is disposed. The steam container includes a chamber, a water supply portion to supply water into the chamber, and a steam discharge portion to discharge steam generated in the chamber into the cooking compartment. The steam heater has a chamber bottom forming portion that is coupled to a lower end of the steam container so as to cover a bottom of the chamber and adapted to heat water supplied into the chamber. The heater covering portion is configured to cover a rim of the steam heater. Covering the rim of the steam heater using the heater covering portion alleviates the risk of power leakage accidents caused when water at the outside of a steam generator comes into contact with the steam heater.
