Method for controlling laundry processing apparatus

1. A method for controlling a laundry processing apparatus, the method comprising:

inputting a command for starting drying;

forwardly-rotating a drying drum and a drying fan;

supplying hot air into the drying drum;

integrating a drying time by operating a timer; and

sensing a dryness of laundry in the drying drum by operating a dryness sensor,

wherein a controller determines that the laundry is tangled, when a dryness sensing value (K) sensed by the dryness sensor is equal to or greater than a first set value (k 1 ) before a first set time (T 1 ) elapses after the drying is started, and

wherein the controller performs a primary laundry untangling process of reversely rotating the drying drum for a second set time (T 2 ).

2. The method of claim 1 , wherein, when the second set time (T 2 ) elapses, a rotational direction of the drying drum is changed such that the drying drum is controlled to be forwardly rotated.

3. The method of claim 2 , wherein the primary laundry untangling process is performed only one time for the second set time (T 2 ).

4. The method of claim 3 , wherein whether the drying is completed is determined after the first set time (T 1 ) elapses, and

wherein a variation (H) of the dryness sensing value is calculated, by the controller, for a specific duration using the sensed dryness value receive from the dryness sensor before the drying is completed.

5. The method of claim 4 , wherein the variation (H) of the dryness sensing value is a result obtained through {(second sensing value−first sensing value)/elapsed time}, and

wherein the second sensing value is greater than the first sensing value.

6. The method of claim 5 , wherein the controller determines that the laundry is tangled when it is determined that the variation (H) of the dryness sensing value is greater than a set value (h), and performs a secondary laundry untangling process of reversely rotating the drying drum for a third set time (T 3 ).

7. The method of claim 6 , wherein, when a time interval, which is taken to increase a dryness sensing value from the first sensing value to the second sensing value, is determined to be less than a set time (t), the controller determines that the laundry is tangled and performs the secondary laundry untangling process of reversely rotating the drying drum for the third set time (T 3 ).

8. The method of claim 6 , wherein, when the third set time (T 3 ) elapses, the rotational direction of the drying drum is changed and the drying drum is controlled to be forwardly-rotated.

9. The method of claim 8 , wherein the secondary laundry untangling process is performed only one time for the third set time (T 3 ).

10. The method of claim 9 , wherein the second set time (T 2 ) is equal to the third set time (T 3 ) or

wherein one of the second set time (T 2 ) and the third set time (T 3 ) is shorter than the other of the second set time (T 2 ) and the third set time (T 3 ).

11. The method of claim 7 , wherein, when the third set time (T 3 ) elapses, the rotational direction of the drying drum is changed and the drying drum is controlled to be forwardly-rotated.

12. The method of claim 11 , wherein the secondary laundry untangling process is performed only one time for the third set time (T 3 ).

13. The method of claim 12 , wherein the second set time (T 2 ) is equal to the third set time (T 3 ) or

wherein one of the second set time (T 2 ) and the third set time (T 3 ) is shorter than the other of the second set time (T 2 ) and the third set time (T 3 ).
