The laundry treating apparatus of claim 4, wherein the driver is configured to rotate the drum less than one full revolution and then stops when the sensor senses the door opening and closing the opening, wherein the display part is configured to display the weight information only when the selection part receives the input of the selection command.
The laundry treating apparatus of claim 1, wherein the driver is configured to rotate and stop the drum after the selection part receives the input of the selection command, wherein the display part is configured to display the weight information after the drum stops rotating.
The laundry treating apparatus of claim 6, wherein, based on that the power part receives the input of the power-on command or the sensor senses the door opening or closing the opening, the driver is configured to rotate the drum only whenthe selection part receives the input of the selection command.
The laundry treating apparatus of claim 6, wherein the driver is configured to rotate the drum less than one full revolution and then stops when the selection part receives the input of the selection command.
The laundry treating apparatus of claim 1, wherein the control panel further comprises: selection partwherein the execution part is configured to receive the input of the execution command after the weight information is displayed after the drum stops rotating.
The laundry treating apparatus of claim 1, wherein the locker is configured to lock the door after the weight information is displayed after the drum stops rotating.
The laundry treating apparatus of claim 1, wherein the display part is configured to display the weight information differently when an amount of the laundry accommodated in the drum varies.

Description

[Technical Field] The present disclosure relates to a laundry treating apparatus and a method of controlling the same. More specifically, it relates to a laundry treating apparatus capable of supplying steam and hot air to laundry to perform a drying cycle including sterilization, wrinkle removal, deodorization, and drying, and a control method thereof. [Background Art] Generally, a laundry treating apparatus refers to a device capable of performing one or more of washing, drying, or managing laundry. Here, the laundry treating apparatus may perform only the washing, drying, or management function, or may perform all the washing, drying, and management functions. Such a laundry treating apparatus includes any course for washing, drying, or managing laundry, and the execution time of the course is calculated based on the weight of the laundry. For example, when the weight of the laundry is large, the execution time is set relatively long. When the weight of the laundry is small, the execution time is set relatively short. FIG. 1 illustrates a method of performing a course by a conventional laundry treating apparatus (see, for example, Korean Patent Application Publication Nos. 10-2009-0077097 and 10-2008-0102611). FIG. 1-(a) illustrates a control method in which a conventional laundry treating apparatus performs a course. Referring to FIG. 1-(a), the conventional laundry treating apparatus may include a power supply step (S1) of supplying power to the laundry treating apparatus by turning on the power button, a selection step (S2) of selecting an appropriate course or option on the control panel of the laundry treating apparatus, and a start step (S3) of pressing a execution button to execute the course in which multiple options are set. When the start step (S3) is performed, a door locking step (S4) may be performed to lock the door to the cabinet. The conventional laundry treating apparatus performs a weight detection step (S5) of detecting the weight based on the applied electrical current while rotating the drum that accommodates the laundry. Once the weight of the laundry is calculated, the controller of the conventional laundry treating apparatus performs a time display step (S6) of displaying the expected execution time of the selected course to the user, and an execution step (S7) of automatically executing the course. As a result, the weight detection step (S5) and the time display step (S6) of the conventional laundry treating apparatus are performed after the user has input the start step (S3) of executing the course. Therefore, the user is forced to input the execution of the course without receiving information about the weight of the laundry or the expected execution time. Consequently, the user cannot actively control the execution time of the course or option, and the time display step (S6) can only provide simple information to the user as a service. Further, when the execution time displayed in the time display step (S6) is not suitable for the user's current intention or situation, the user is not given the opportunity to actively take action by adding or removing laundry. Also, in conventional laundry treating apparatuss, when the execution time of the selected course or option does not meet the intention, the user cannot cancel or change the course unless they actively take measures, such as turning off the power of the washing machine. This inconvenience becomes more pronounced when remotely controlling the conventional laundry treating apparatus. FIG. 1-(b) illustrates the rotation state of the drum when the conventional laundry treating apparatus senses weight. Referring to FIG. 1-(b), the conventional laundry treating apparatus rotates the drum D in direction I for at least one full revolution to detect the weight of the laundry L. Specifically, while rotating the drum D in direction I, the conventional laundry treating apparatus measures the current applied to or output from the driver that rotates the drum, thereby calculating the weight of the laundry L. When the conventional laundry treating apparatus rotates the drum D to detect the weight, the laundry L on the bottom surface of the drum rises inside the drum D and falls in direction II due to gravity, colliding with the inner wall of the drum and affecting the current of the driver. Therefore, in order to accurately detect the weight of the laundry L despite variations in the driver current, the conventional laundry treating apparatus must rotate the drum D continuously in direction I for at least one full revolution and align the applied or output current values, which is a limitation. As a result, the time required for the conventional laundry treating apparatus to detect the weight of the laundry may inevitably exceed the time needed to rotate the drum continuously. In addition, in conventional laundry treating apparatuss, because the time required for the weight detection step (S5) is set relatively long, the time display s
