Abstract
A bread producing machine comprises a baking case for accommodating bread materials, a baking chamber for accommodating the baking case, a mixing, kneading means for mixing, kneading the bread materials within the baking case, a heating means for heating the baking case, an air inlet route and an exhaust route including the baking chamber a fan for compulsory blast use is disposed in the course of the exhaust rate. The exhaust route is located at its one end above the baking case so as to confront the upper portion side wall of the baking chamber as an air inlet port, and confronts at its other end an outer side exhaust port provided in an outer cover. The ventilation by the driving operation of the fan becomes a suction type, such that the baking chamber is set in the negative pressure region so that the steam venting step after the bread baking step positively and quickly exhausts the steam existing not only on the top surface of the bread, but also in the gap between the bread periphery and the bread baking case.
