Bread maker and control method thereof
First Claim
1. A bread maker having an oven compartment and an electric component compartment, a pair of parallel kneading drums inside the oven compartment to which are attached opposite ends of a mixing bag containing bread ingredients, the kneading drums reversing rotary direction periodically, and a drum driving part in the electric component compartment rotating the kneading drums, the bread maker comprising:
- a rotation sensing part sensing a rotation rate of one of the kneading drums; and
a controller stopping the drum driving part when the sensed rotation rate is greater than a predetermined rotation rate.

Abstract
A bread maker having an oven compartment and an electric component compartment, a pair of parallel kneading drums inside the oven compartment that reverse rotary direction periodically and to which are attached opposite ends of a mixing bag containing bread ingredients, and a drum driving part in the electric component compartment rotating the kneading drums. A rotation sensing part senses a rotation rate of one of the kneading drums. A controller stops the drum driving part when the sensed rotation rate is greater than a predetermined rotation rate.

25. A sensor for a bread maker having parallel kneading drums that rotate clockwise and counterclockwise to reciprocate a bag of ingredients attached to the kneading drums, comprising:
-
a first disk rotating with a first one of the kneading drums and having a projection extending radially therefrom;
a second disk, adjacent the first disk, rotating with the first kneading drum and having a plurality of projections at regular intervals extending radially therefrom;
a first disk sensor sensing rotation of the first disk and having a first light emitter and a first light receiver, the first light emitter emitting light to the first light receiver and the projection of the first disk passing between the first light emitter and the first light receiver as the first disk rotates, the first disk sensor generating a pulse signal with each interruption of the light by the projection of the first disk;
a second disk sensor sensing rotation of the second disk and having a second light emitter and a second light receiver, the second light emjtter emitting light to the second light receiver and the projections of the second disk passing between the second light emitter and the second light receiver as the second disk rotates, the second disk sensor generating a pulse signal with each interruption of the light by the projections of the second disk; and
a controller receiving the pulse signals and stopping rotation of the kneading drums when a pulse width of the pulse signals is greater than a predetermined pulse width. - View Dependent Claims (26, 27, 28, 29, 30)
