Abstract

A smaller heating cooker including an inner casing and an outer casing. The inner casing includes a first inner sidewall, a second inner sidewall, a third inner sidewall, and a fourth inner sidewall. The outer casing includes a first outer sidewall, a second outer sidewall, a third outer sidewall, and a fourth outer sidewall. The size of gap between an inner surface of the first outer sidewall and an outer surface of the first inner sidewall and the size of a gap between an inner surface of the second outer sidewall and an outer surface of the second inner sidewall are smaller than the size of a gap between an inner surface of the third outer sidewall and an outer surface of the third inner sidewall and the size of a gap between an inner surface of the fourth outer sidewall and an outer surface of the fourth inner sidewall.
