Abstract
Disclosed is an apparatus for detecting a belt-cutoff of a dryer. The apparatus comprises a drying drum accommodating a laundry therein; a motor applying a rotational force to the dry drum; a belt wound around the drying drum and a rotating shaft of the motor; and a belt cut detecting unit provided adjacent to the motor in order to sense the belt-cutoff, wherein the belt cut detecting unit is pressed as the motor is rotated by a turning moment when the belt is cut off.
Claims23
An apparatus for detecting a belt-cutoff of a dryer, comprising:
- a drying drum accommodating a laundry therein;
- a motor applying a rotational force to the dry drum;
- a belt wound around the drying drum and a rotating shaft of the motor;
- and
- a belt cut detecting unit provided adjacent to the motor for detecting the belt-cutoff,
- wherein the belt cut detecting unit is pressed as the motor is rotated by a turning moment when the belt is cut off.
An apparatus for detecting a belt-cutoff of a dryer, comprising:
- a dry drum;
- a motor rotating the drying drum and provided with a pressing element protruded from one side of an outer circumference thereof;
- a spring supporting the motor;
- a belt wound around the drying drum and a rotating shaft of the motor;
- and
- a micro switch contacting with the pressing element when the belt is cut off.
A method for detecting a belt-cutoff of a dryer, comprising the steps of:
- rotating of the drying drum by an input of an operation command;
- turning on the belt cut detecting unit as the belt wound around the drying drum is cut off;
- and
- stopping the operations of the heater and the motor as soon as the belt cut detecting unit is turned on.
A method for detecting a belt-cutoff of a dryer, the method comprising judging the cutting of a belt which connects a drying drum with a motor through an operation of applying pressure on a belt cut detecting unit while the motor itself rotates.
