A laundry treating apparatus, particularly, a laundry treating apparatus using steam is disclosed. The laundry treating apparatus such as a washing machine, a dryer, a drying and washing machine is an apparatus which washes or dries articles such as clothes. The laundry treating apparatus includes an operation course including a drying process in which hot air is supplied into a drum adapted to accommodate articles to dry the articles and a cooling process in which cool air is supplied into the drum to cool the articles, wherein the operation course further includes a steam process in which steam is supplied into the drum, and the laundry treating apparatus includes a controller which controls a heater adapted to generate the steam such that an operation time point of the heater varies according to an amount of the articles. The laundry treating apparatus includes a drum adapted to accommodate articles, a control panel adapted to provide an interface with a user, and a controller to perform a steam process for supplying steam into the drum, wherein the controller controls a heater adapted to generate the steam to perform the steam process such that an operation time point of the heater varies according to an amount of the articles.

1. A controlling method for a laundry treating apparatus comprising: an operation course including a drying process in which hot air is supplied into a laundry accommodating portion adapted to accommodate articles to dry the articles anda cooling process to cool the articles,wherein the operation course further includes a steam process in which steam is supplied into the laundry accommodating portion,wherein the controlling method includes controlling a heater adapted to generate the steam such that an operation start time point of the heater is earlier as an amount of the articles in the laundry accommodating portion is more, andwherein the operation start time point of the heater is in either the drying process or the cooling process. 2. The controlling method according to claim 1, wherein the steam process is performed during the cooling process. 3. The controlling method according to claim 2, wherein with regard to a time period until the steam process begins after an operation of the heater is started, the operation start time point of the heater varies within a section from the last period of the drying process to an initial period of the cooling process according to the amount of the articles. 4. The controlling method according to claim 2, wherein a time period from a start of the cooling process to an end of the steam process is invariable. 5. The controlling method according to claim 1, wherein operation conditions of the drying process vary according to dryness detected in the drying process. 6. The controlling method according to claim 5, wherein the amount of the articles is determined according to the detected dryness. 7. The controlling method according to claim 5, wherein the operation conditions include at least one of a drying process time, a temperature in the laundry accommodating portion, and a capacity of a heater adapted to heat air supplied into the laundry accommodating portion. 8. The controlling method according to claim 1, wherein fine water particles and hot air are supplied into the laundry accommodating portion instead of the steam in the steam process, and the operation start time point of the heater is replaced by a time point at which the fine water particles and the hot air are supplied into the laundry accommodating portion. 9. A controlling method for a laundry treating apparatus comprising a laundry accommodating portion adapted to accommodate articles, a control panel adapted to provide an interface with a user, and a controller, wherein the control panel includes: a course selection part which allows the user to select a steam-available course, which selectively includes a steam process for supplying steam into the laundry accommodating portion, as an operation course; andan option selection part which allows the user to additionally select an option course including the steam process in the selected course,the controlling method comprising: controlling a heater adapted to generate the steam when the steam-available course and the option course are selected such that an operation start time point of the heater is earlier as an amount of the articles in the laundry accommodating portion is more, andwherein the heater is turned on during the steam-available course. 10. The controlling method according to claim 9, wherein the steam-available course includes a drying process in which hot air is supplied into the laundry accommodating portion to dry the articles and a cooling process to cool the articles. 11. The controlling method according to claim 9, wherein the steam process is performed during the cooling process. 12. The controlling method according to claim 11, wherein with regard to a time period until the steam process begins after an operation of the heater is started, the operation start time point of the heater varies within a section from the last period of the drying process to an initial period of the cooling process according to the amount of the articles. 13. The controlling method according to claim 9, wherein the operation start time point of the heater varies according to the amount of the articles. 14. The controlling method apparatus according to claim 9, wherein the option course includes a course in which the steam process is performed such that the articles have a moisture content of 5% or less after the drying process is completed. 15. The controlling method according to claim 9, wherein the steam-available course includes a drying process in which hot air is supplied into the laundry accommodating porting to dry the articles, and the option course includes a cooling process to cool the articles and the steam process. 16. The controlling method according to claim 15, wherein the steam process is performed during the cooling process. 17. The controlling method according to claim 16, wherein with regard to a time period until the steam process begins after an operation of the heater is started, the operation start time point of the heater varies within a section from the last period of the drying process to an initial period of the cooling process according to the amount of the articles. 18. The controlling method according to claim 17, wherein when the amount of the articles is determined to be equal to or smaller than a specific amount, the laundry accommodating portion, which is rotatably disposed in a cabinet as a drum, is not driven during the cooling process. 19. The controlling method according to claim 9, wherein fine water particles and hot air are supplied into the laundry accommodating portion instead of the steam in the steam process, and the operation start time point of the heater is replaced by a time point at which the fine water particles and the hot air are supplied into the laundry accommodating portion.
