Clothes treatment apparatus, and control method for clothes treatment apparatus

A control method of a laundry treatment apparatus including:

• a drum configured to form a space in which clothes are stored and having an entrance formed on a front surface thereof;
• a fixing panel;
• an output shaft configured to pass through the fixing panel so as to be connected to the drum;
• an input shaft configured to be rotated by a motor and form coaxiality with the output shaft;
• a gear unit configured to connect the input shaft to the output shaft to rotate the output shaft at a rotation speed lower than a rotation speed of the input shaft;
• and a drying part configured to supply heated air or unheated air to the drum, the control method comprising:
• a laundry weight determination operation of determining the amount of clothes stored in the drum;
• a setting operation of setting a rotation speed that causes a centrifugal force of 1G or less according to the amount of clothes to a reference rotation speed;
• an air supply operation of supplying heated air to the drum by the drying part;
• and
• a first motion execution operation of rotating the drum at a reference rotation speed, a first rotation speed set to be higher than the reference rotation speed, and a second rotation speed set to be lower than the reference rotation speed,
• wherein the first motion execution operation includes:
• rotating the drum in a first direction set to any one of a clockwise direction and a counterclockwise direction at the reference rotation speed;
• rotating the drum in the first direction at the first rotation speed;
• and
• rotating the drum in the first direction at the second rotation speed.
