Automatic bread-making device
First Claim
1. An automatic bread-making device, comprising:
- a housing with a baking chamber;
a cooking vessel removably arranged in said chamber and provided at its bottom with a rotating shaft;
a cooking heater arranged in said cooking chamber to heat said vessel;
a kneading blade removably attached to said rotating shaft; and
a driving means for rotating said kneading blade through the rotating shaft, wherein said kneading blade is provided with a bore for attachment to the rotating shaft, said bore having at least one crescent-shaped projection formed therein, and wherein said rotating shaft is provided at its upper portion with at least one groove extending in the direction parallel to a line which intersects with an axis of the shaft at a right angle to form a head adapted to be engaged with said projection of the blade when said shaft is in revolution, said head being partially cut in such a manner that it may pass through an opening defined by an inner wall of the bore and a free end of said projection.

Abstract
An automatic bread-making device comprises a housing, a cooking vessel removably arranged therein and provided at its bottom with a rotating shaft, a kneading blade removably attached to the rotating shaft, and a driving means for rotating the kneading blade through the rotating shaft. The kneading blade is providing with at least one crescent-shaped projection at a wall surface of a bore for attachment of the blade to the rotating shaft, while the rotating shaft is provided at its upper portion with at least one groove extending in the direction parallel to a line which intersects the axis of the shaft to form a head with a figure similar to that of an opening formed between the inner wall of the bore and a free end of the projection. The kneading blade is attached to the rotating shaft so that the head of the rotating shaft is engaged with the projection of the blade when the head of the shaft is arranged in the bore of the blade. The device further comprises a sequence control system for controlling the driving means and heaters, and a coupling means between the rotating shaft and the driving shaft. During kneading, the driving shaft is rotated in such a manner that, when revolution of the blade is to be reversed, the driving shaft is reversely driven and stopped just before engagement of the driving disk with the coupling member, and then redriven in the same direction.
