According to a preferred embodiment of the method for controlling a drying apparatus of the present invention, as shown in FIG. 4, a drying step S1 for drying a drying object and a drying object 40 in which drying is completed, the door 3 in the drying drum 10. It comprises a moving step (S2) to move to the side.

First, the drying step will be described.

When the user wants to dry the object to be dried 40, the drying drum 10 is rotated while pressing the operation button after putting the wet object to be dried 40 into the drying drum 10, and the drying step S1. ) Starts.

Then, the blower 17 is operated to suck the air inside the drying drum 10 through the lint duct 15. In this case, air is introduced into the drying drum 10 through the hot air supply duct 12 due to the pressure difference.

At this time, the air supplied to the hot air supply duct 12 is heated by the heater assembly 20 and introduced as hot air in a high temperature and a dry state.

The hot air introduced into the drying drum 10 absorbs the moisture contained in the drying object, and then exits the drying drum 10 through the outlet assembly 13. At this time, the air of the drying drum 10 is discharged by the suction force of the blower (17). Then, this substance such as dust or seams contained in the air exiting the outlet assembly 13 is filtered while passing through the lint filter 14.

When the above-described process is repeated and the drying step S1 ends, the moving step S2 is then executed.

5 is a flowchart showing a moving step, and FIGS. 2 and 3 are sectional views schematically showing the interior of the drying apparatus in the moving step.

The moving step (S2) is a step of allowing the drying object 40, which has been completely dried in the drying drum, to move to the front side of the drying drum 10, that is, the door 3, to be piled in one place.

At this time, the strength of the wind 50 blowing into the drying drum 10 in the moving step (S2) is preferably stronger than the intensity of the hot air supplied into the drying drum (10) in the drying step (S1).

This is because the wind 50 blowing in the moving step (S2) may fall while moving to the door 3 side of the drying drum 10 when the drying object 40 is strong enough to fly. .

Therefore, a blower fan (not shown) and a motor (not shown) for driving the blower fan (not shown) are not provided separately, but as the blower 17 inside the drying drum 10 in the moving step. Drying apparatus having a structure for blowing air is preferably rotated at a higher speed than the drying step (S1) of the motor 30 for rotating the blower 17 to generate a stronger wind.

In addition, a reverse rotation step (S21) in which the drying drum 10 rotates in the reverse direction may be included. This is because the drying drum 10 is alternately stirred to eliminate the eccentricity.

That is, after the drying drum 10 rotates in one direction for a predetermined time, the drying object 40 in the drying drum 10 moves to the door 3 side while rotating in the reverse direction for a predetermined time.

Of course, the blowing step (S22) is also maintained in the reverse rotation step (S21).

In addition, the movement step S2 of the present embodiment may be terminated after each of the above-described steps are performed once, or may be configured such that each step is repeated several times.

In addition, the number of times each step of the moving step (S2) and the time it is performed may be adjusted according to the amount of the drying object 40 in the drying drum (10).

Therefore, when the movement step (S2) is completed, the drying object 40 in the drying drum 10 is the front side of the drying drum 10 by the rotation and wind of the drying drum 10, that is, the door 3 side Being concentrated in the user can open the door (3) after the hand deep into the drying drum 10, or can be taken out without having to look inside the drying drum 10, thereby improving the user's convenience.

In addition, the present invention can be applied not only to the drying apparatus described above, but also to a washing machine provided with a drying function of a drum type, and thus a detailed description thereof will be omitted since such a configuration is obvious to those skilled in the art.

As described above, according to the drying apparatus of the present invention and a control method thereof, the dried object to be dried is concentrated on the door side of the drying drum, so that the user can take it out immediately after opening the door. There is no need to put deep, or look inside the drying drum has the effect of improving the convenience of the user.
