Description

A laundry treating apparatus The present invention relates to a garment processing device. More specifically, it relates to a garment processing device that detects the volume of fabric immediately upon inputting power and provides an appropriate water level corresponding to that volume. 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. In addition, the clothing processing device is classified into a front-load type washing machine, which has an opening for feeding clothing at the front of the cabinet, and a top-load type washing machine, in which the opening is located at the top of the cabinet. Specifically, conventional top-load type washing machines rotate the drum and the pulsator simultaneously with a single drive unit, or rotate the pulsator independently of the drum, and additionally place a clutch between the drive unit and the pulsator. In such conventional top-load type washing machines, the load or current value applied to the drive unit is measured when the drum is rotated by the drive unit in order to detect the weight of the clothes contained inside the drum. At this time, since there is a possibility that the clothes contained in the drum may be damaged if the pulsator and the drum rotate differently, the conventional clothing processing device necessarily performed a process of aligning the arrangement of the clutch unit in order to rotate the pulsator and the drum simultaneously. Conventional top-load type washing machines included a water level selection unit that allowed the user to directly set the water level (hereinafter referred to as the water level) required for washing clothes. In conventional top-load type washing machines, when a user inputted a water level selection, the default water level set at the time of manufacture was displayed. At this time, when the user inputted an action, the washing proceeded according to the aforementioned default water level. For example, the default water level may be set to level 7 (ranging from level 1 to level 10). In this case, when the user inputs the water level selection unit and the execution unit in sequence, water is supplied at level 7 regardless of the weight of the clothing. Therefore, there was a problem where a large amount of water was dispensed unknowingly because the default water level was displayed when the user entered the water level selection section, even if a small amount of laundry was loaded. In addition, when washing proceeds at the default level even though a small amount of laundry is input, the garment processing device experiences imbalance due to clumping of the clothes, which reduces the efficiency of spin-drying or increases vibration noise. In addition, there was a problem where if the user changed the water level through the level selection section even though the default water level was appropriate, clothes would not be washed properly or water could be wasted. In addition, there was the inconvenience of having to press the water level selection button multiple times to change the water level from the above default level to a level suitable for the laundry.
