BACKGROUND

1. Field

The present specification relates to a method of controlling a water dispensing apparatus.

2. Background

Various devices may dispense water. For example, a water purifier or a refrigerator may use various chemical and/or physical filtration methods to treat water supplied from a water source, such as a well or a water utility, to remove impurities and supply the filtered water. For example, a water dispenser may be classified into a nature filtering type, a direct filtering type, an ion exchange resin type, a distillation type, a reverse osmosis type, etc. according to the purification principle or method.

In a water dispensing apparatus, a cup or container to receive water (or other liquid) is typically placed below a water discharge nozzle, and water is supplied when a user presses a water supply or discharge button. When the user determines that a desired amount of water is supplied, the user stops pressing the button to stop the supply of water. Therefore, the user needs to continuously check the amount of water until the desired amount of water is discharged. When the user is distracted or miscalculates the amount of discharged water, the user may be slow to stop pressing the discharge button such that an excess amount of water is discharged and water overflows the user's container. When hot water is being discharged, a user's hand may be burned.

Certain types of water dispensing apparatus may have an auto water discharge button to discharge a predetermined amount of water. However, the amount of water discharged by pressing the automatic water discharge button once is typically small (e.g., 50 ml) and unrelated to a size of a user's container. Therefore, in order to fill a large cup with water, the user may need to press the automatic water discharge button several times, such as pressing the above-described automatic water discharge button for 50 ml ten times to fill a large cup with 500 ml of water. Although the preset discharge amount may be adjusted, this manual adjustment may be burdensome and would need to be repeatedly performed to adjust for different containers.
