Abstract

An automatic bread baking machine wherein, at a predetermined time prior to a preset time, water is supplied into a container, in which the ingredients of bread are mixed into the water by rotating a rotary vane provided in the container, producing dough. A fixed rod is provided in the container adjacent to and spaced from the rotary vane, and the dough is twined around the fixed rod by the rotary vane and kneaded at comparatively low speed by the cooperation of the rotary vane and the fixed rod. The dough temperature is sensed by a temperature sensor disposed in the fixed rod, and when the sensed temperature has reached a predetermined value, the dough kneading operation is terminated. The water is supplied into the container from a water tank covered with a heat-insulating layer. An ice box for containing ice is provided in the water tank, and when the ambient temperature is higher than a predetermined value, cold water is supplied to the container.

Dependent claims

An automatic bread baking machine comprising:

housing;
a container removably mounted in the housing, for containing the ingredients of bread;
water supply means mounted in the housing;
kneading means for kneading the ingredients of bread with water into dough in the container, said kneading means comprising a rotary shaft which extends through the bottom of said container, at least one rotary vane mounted on an upper end of said rotary shaft inside of said container to extend perpendicularly to said rotary shaft, a fixed rod mounted in said container adjacent to and spaced from said rotary vane, said fixed rod being oriented transverse to the axis of rotation of said rotary shaft, and a motor mounted in said housing outside of said container for driving said rotary shaft to effect movement of said vane past said fixed rod thereby to cause the dough being kneaded to turn about said fixed rod as said vane rotates in said container;
a heater in the housing for baking the dough in the container;
and
a controller for performing, in a sequential order, a kneading step in which water is supplied from the water supply means to the container and the kneading means is driven to produce the dough, a fermentation step for fermenting the dough, and a baking step for baking the fermented dough by use of the heater.
