Laundry treating apparatus having a cleaning nozzle and method for controlling the same

A laundry treating apparatus, comprising:

• a main body having a tub, a drum disposed inside the tub, and a circulation path to circulate air from the tub;
• a lint filter provided in the circulation path;
• a lint filter nozzle provided in the circulation path to inject water to the lint filter;
• a first water supply passage having one side connected to a water supply source and another side connected to the lint filter nozzle;
• a first water supply valve to open and close the first water supply passage;
• an rpm sensor to sense an rpm of the drum;
• and
• a controller configured to:
• determine that the laundry treating apparatus is to operate in a drying course;
• when the laundry treating apparatus is determined to operate in the drying course, determine when the sensed rpm of the drum is more than a prescribed rpm;
• and
• in response to the determination that the sensed rpm of the drum during the drying course is more than the prescribed rpm, control the first water supply valve to supply water to the lint filter nozzle during the drying course, and
• wherein the prescribed rpm is set such that water dropping toward the drum through the lint filter bounces to outside of the drum by a rotation force of the drum without being introduced into the drum,
• wherein the controller is configured to control the first water supply valve to be opened and closed a prescribed number of times such that water is intermittently supplied to the lint filter when the rpm of the drum sensed by the rpm sensor, during the drying course, is more than the prescribed rpm.
