Abstract
A controlling method for a dryer is provided. The controlling method includes the steps of rotating a drum in a first direction and a second direction which is an opposite direction to the first direction by a motor, measuring the load of the motor and identifying the weight of drying materials based on the lower motor load among the load of the motor measured during rotation in the first direction and the load of the motor measured during rotation in the second direction.
Claims20
A controlling method for a dryer, the method comprising:
- rotating a drum in a first direction and a second direction which is an opposite direction to the first direction by a motor;
- rotating a fan by the motor in a direction of rotation for the drum;
- measuring a load of the motor;
- determining a lower motor load based on the fan rotating in a direction that does not generate air flow;
- and
- identifying a weight of drying materials disposed in the drum based on the lower motor load.
A controlling method for a dryer, the method comprising:
- rotating a drum in a first direction during a predetermined time period, and rotating the drum in a second direction which is an opposite direction to the first direction during a predetermined time period;
- rotating a fan in a direction of rotation for the drum;
- comparing motor loads in each rotation direction measured while the drum is rotated in the first and second directions and selecting a rotation direction which is measured as a lower motor load, wherein the lower motor load is based on the fan rotating in a direction that does not generate air flow;
- rotating the drum, alternately, each of:
- two or more times of first stirring sections where the drum is rotated in the first direction, and
- two or more times of second stirring sections where the drum is rotated in the second direction;
- and
- identifying a weight of drying materials based on motor loads measured in the two or more times of stirring sections rotating in the selected direction.
A dryer comprising:
- a main body including a door;
- a heater arranged inside the main body;
- a drum rotatably arranged inside the main body;
- a motor configured to drive the drum;
- a power transmission member configured to obtain power from the motor and rotate the drum in a first direction and a second direction which is an opposite direction to the first direction;
- a fan configured to obtain power from the motor, provide hot wind to the drum, and rotate in the same direction as the drum;
- a current detection sensor configured to measure motor loads of the motor in the first direction and the second direction;
- and
- a processor,
- wherein the processor is configured to:
- measure a load of the motor while the drum is rotated in the first direction and in the second direction,
- determine a lower motor load based on the fan rotating in a direction that does not generate air flow, and
- identify a weight of drying materials based on the lower motor load among a load of the motor measured during rotation in the first direction and a load of the motor measured during rotation in the second direction.
A non-transitory computer-readable recording medium including a program for executing a method for measuring a weight of drying materials housed inside a drum of a dryer, the method comprising:
- rotating the drum in a first direction and a second direction which is an opposite direction to the first direction by a motor;
- rotating a fan by the motor in a direction of rotation for the drum;
- measuring a load of the motor;
- determining a lower motor load based on the fan rotating in a direction that does not generate air flow;
- and
- identifying the weight of drying materials based on the lower motor load among the load of the motor measured during rotation in the first direction and a load of the motor measured during rotation in the second direction.
