Description

A laundry treating apparatus and a control method of the same The present invention relates to a clothing processing device and a method for controlling said clothing processing device. Generally, the term "clothing processing device" refers to a device capable of washing, drying, or performing washing or drying of clothing, etc. Here, the clothing processing device may perform only washing or drying functions, or may perform both washing and drying. Such a garment processing device is equipped with any course or option for performing washing or drying of garments, and the execution time of said course or option is calculated based on the volume of the garments. For example, if the volume of garments is large, the execution time will be set relatively long, and if the volume of garments is small, the execution time will be set relatively short. FIG. 1 illustrates a control method for performing any course or option of a conventional clothing processing device. (See Korean Patent Publications No. 10-2009-0077097 and 10-2008-0102611, etc.) FIG. 1(a) illustrates a control method in which a conventional clothing processing device performs any course or option. Referring to FIG. 1(a), a conventional clothing processing device may include a power supply step (s1) for supplying power to the clothing processing device by inputting (on) a power button, a selection step (s2) for selecting an appropriate course or option on the control panel of the clothing processing device, and a start step (s3) for inputting an execution button to execute the course or option. In the case where the conventional clothing processing device is equipped as a front load type washing machine having an opening for introducing clothing at the front of the cabinet, when the starting step (s3) is performed, a door locking step (s4) for fixing the opening to the cabinet may be performed. Subsequently, the conventional clothing processing device performs a volume detection step (S5) in which it detects the volume of clothing through an applied current value while rotating a drum or the like that receives the clothing. When the volume of the clothing is calculated, the control unit of the conventional clothing processing device performs a time display step (S6) in which it displays the expected execution time of the selected course or option to the user, and performs an execution step (S7) in which it automatically executes the course or option. However, the load detection step (S5) and time display step (S6) of the conventional clothing processing device are performed after the start step (S3) in which the user executes a course or option. Therefore, there was a problem in that the user was forced to input the execution of a course or option without receiving information about the load of clothing or the expected execution time. As a result, there was a problem in that the user could not actively control the execution time of the course or option, and the time display step (s6) could not perform a role beyond simply displaying simple information to the user at the service level. Furthermore, conventional clothing processing devices had a problem in that they did not allow the user to take active measures, such as adding or reducing clothing, even if the execution time displayed in the time display step (s6) did not match the user's current intention or situation. In addition, conventional garment processing devices had a problem in that even if the execution time of a selected course or option did not match the intention, it was impossible to cancel or change the course or option unless active measures were taken, such as manually turning off the washing machine's power again. This inconvenience was further exacerbated when the aforementioned conventional clothing processing device was controlled remotely. FIG. 1(b) illustrates the rotational state of the drum when a conventional clothing processing device detects the amount of fabric. Referring to FIG. 1(b), a conventional clothing processing device rotated the drum (D) in the I direction to detect the amount of clothing (L). Specifically, the conventional clothing processing device calculated the weight of the clothing (L) by measuring the current value applied to or output to the driving unit that rotates the drum (D) while rotating the drum (D) in the I direction. In a conventional clothing processing device, when the drum (D) is rotated to detect the amount of material, the clothing (L) on the bottom surface of the drum rises inside the drum (D) and then falls in direction II due to gravity, inevitably separating from the inner wall of the drum. Therefore, conventional clothing processing devices had a limitation in that they had to align the applied or output current values while continuously rotating the drum (D) in the I direction for at least one rotation to detect the accurate weight of the clothing (L). As a result, conventional clothing processing devices had a problem in that the
