Abstract: A bread maker having upper and lower rollers, a baking tray, a housing forming an oven chamber, a door attached to the front of the housing, a baking tray detachably mounted in the oven chamber, and a sensor. The sensor senses whether the baking tray is mounted in the oven chamber. The sensor is mounted in at least one of the housing and the door and moves back and forth a predetermined distance depending on contact with the baking tray. A sensing switch which senses the movement of the sensor.

Abstract: A bread maker, including a main body having a baking space and kneading drums located at an upper part and a lower part in the baking space. The kneading drums hold opposite ends of a mixing bag. A movable tray member has a plurality of combining projections at opposite side walls thereof. A fixed tray member positioned opposite the movable tray member forms a slit through which the mixing bag passes. A tray holder is coupled to each end of the fixed tray member and the movable tray member. Each tray holder fixedly supports the fixed tray member, and has a plurality of guide grooves accommodating the combining projections to rotatably support the movable tray member. Anchoring prominences are on the guide grooves adjacent to the fixed tray member, preventing the combining projections from breaking away from the guide grooves when the movable tray member rotates.

Abstract: A bread maker including an oven compartment, kneading drums spacedly disposed in parallel inside the oven compartment, and a drum driving part rotating one of the kneading drums in clockwise and counterclockwise directions. Link shafts eccentrically project from the kneading drums and rotate about each respective rotation axis thereof. A connecting rod connects the link shafts and transmits a rotary movement between the kneading drums.

Abstract: A bread maker including an oven compartment, parallel kneading drums inside the oven compartment that alternate between winding and unwinding rotations, and a drum driving part rotating the kneading drums. Each kneading drum includes a rotation shaft rotating according to the drum driving part; a hollow, cylindrical drum member disposed concentrically along an axis of the rotation shaft; and a clutch between the rotation shaft and the drum member, transmitting a rotary movement from the rotation shaft to the drum member in one direction and allowing the drum member to freewheel in the other direction.

Abstract: A bread maker having a main body forming an oven compartment, a door, a pair of parallel kneading drums, a barcode reader to read a barcode printed on a mixing bag and a reader holder. The reader holder includes a holder body, a sensing lever adjacent to a kneading drum with one end connected to one end of the holder body and the other end protruding from the main body towards the door, the sensing lever being pushed back by the door when the door is closed, and a reader supporting part extending from the holder body towards the door and supporting the barcode reader. The barcode reader moves into a reading position near the adjacent kneading drum when the door is opened and moves into a releasing position distant from the adjacent kneading drum when the door is closed.

Abstract: A bread maker having an oven compartment, a door opening and closing the oven compartment, a fixed kneader with a first kneading roller, and a rotatable kneader with a second kneading roller. The rotatable roller rotates between a kneading position at which the first kneading roller and the second kneading roller face each other, and a released position at which the second kneading roller is spaced apart from the first kneading roller. A spring has a first end attached to a side wall of the oven compartment and a second end coupled to the rotatable kneader, and elastically returns the rotatable kneader to the kneading position as the door is closed and elastically maintains the rotatable kneader at the released position when the door is opened. A pusher in the door pushes the rotatable kneader from the released position to the kneading position as the door is closed.

Abstract: A sealing machine for sealing a pack filled with one or more objects, including a main case; a first sealing member provided in the main case; a second sealing member facing the first sealing member; a movable supporting part supporting the second sealing member and allowing the second sealing member to move near to, and away from, the first sealing member; and a heater provided in at least one of the first sealing member and the second sealing member to heat and melt the pack interposed therebetween.

Abstract: A bread maker includes upper and lower rollers and a bar code scanner. The upper and lower rollers wind a mixing bag containing bread ingredients to form dough. The bar code scanner reads a bar code attached to the mixing bag so that, as the mixing bag is wound by rotation of the upper and lower rollers, the bar code scanner reads the bar code while being in contact with the bar code wound around one of the upper and lower rollers. The upper roller includes flat and arcuate portions. The flat portion is provided with an arcuate guide section to form a circular track together with the arcuate portion.
