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 the same. Generally, the term "clothing processing device" refers to a device capable of performing one or more of washing, drying, and care of clothing. Here, the clothing processing device may perform only washing, drying, or care functions, or may perform washing, drying, and care functions. Such a garment processing device is equipped with any course for washing, drying, or managing garments, and the execution time of said course is calculated based on the weight of the garment. For example, if the weight of the garment is large, the execution time will be set relatively long, and if the weight of the garment is small, the execution time will be set relatively short. FIG. 1 illustrates a method for performing any course 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 an arbitrary course. Referring to FIG. 1(a), a conventional clothing processing device may include a power supply step (T1) for supplying power to the clothing processing device by inputting (on) a power button, a selection step (T2) for selecting an appropriate course or option on the control panel of the clothing processing device, and a start step (T3) for inputting an execution button to execute a course with multiple options set. When the above starting step (T3) is performed, a door locking step (T4) for locking the door to the cabinet may be performed. A conventional clothing processing device performs a weight detection step (T5) that detects the weight of the clothing through an applied current value while rotating a drum or the like that receives the clothing. When the weight of the clothing is calculated, the control unit of the conventional clothing processing device performs a time display step (T6) that displays the estimated execution time of the selected course to the user, and performs an execution step (T7) that automatically executes the course. Consequently, the weight detection step (T5) and the time display step (T6) of the conventional clothing processing device are performed after the start step (T3) in which the user executes the course. Therefore, there was a problem in that the user was forced to input the execution of the course without receiving information about the weight of the 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 (T6) was not suitable for 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 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 weight. Referring to FIG. 1(b), a conventional clothing processing device rotated the drum (D) at least once in the I direction to detect the weight of the clothing (L). Specifically, a conventional clothing processing device calculates 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 weight, the clothing (L) on the bottom surface of the drum rises inside the drum (D) and then falls in direction II due to gravity, colliding with the inner wall of the drum and affecting the current value of the driving unit. 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) even with deviations in the current values of the driving unit. As a result, conventional clothing processing devices had a problem in that the time required to detect the weight of the clothing inevitably exceeded the time required to continuously rotate the drum. In addition, conventional clothing processing devic
