Abstract

The disclosure provides a washing machine and method for controlling the same. An embodiment of the washing machine includes an auxiliary washing unit placed below a door arranged on top of a main body; an input unit for receiving instructions to start and stop auxiliary washing; and a water supply unit for supplying water to the auxiliary washing unit if the instruction to start water supply is input, and stopping supplying water to the auxiliary washing unit if the instruction to stop water supply is input.

First claim

What is claimed is:

1. A washing machine comprising:
a main body having an opening at an upper side of the main body;
a door to open and close the opening;
a water supply unit including:
a main water supply passage through which to supply water to the washing machine for machine-washing, and
an auxiliary water supply passage through which to supply water to the washing machine for hand-washing;

an input unit to receive an input for starting supplying water through the auxiliary water supply passage and an input for stopping supplying water through the auxiliary water supply passage; and
a control unit configured to:
prevent the water supply unit from starting supplying water through the auxiliary water supply passage when the input unit receives the input for starting supplying water while the door is closed, and
stop supplying water through the auxiliary water supply passage when the input unit receives the input for stopping supplying water while the water is supplied through the auxiliary water supply passage.

2. The washing machine according to claim 1 , further comprising:
a door position sensing unit to sense the door being closed.

3. The washing machine according to claim 2 , wherein the door position sensing unit comprises a magnet disposed at the door.

4. The washing machine according to claim 1 , wherein the control unit is further configured to stop supplying water through the auxiliary water supply passage after supplying water through the auxiliary water supply passage for a predetermined duration.

5. The washing machine according to claim 1 , further comprising:
an outer tub to contain water;
a rotatable tub disposed in the outer tub and configured to accommodate laundry received through the opening; and
a water level sensing unit configured to sense whether a water level of the outer tub reaches a predetermined water level,
wherein the control unit is further configured to stop supplying water through the auxiliary water passage based on the water level sensing unit sensing that the water level of the outer tub reaches the predetermined water level.

6. The washing machine according to claim 1 , further comprising:
an outer tub to contain water;
a rotatable tub disposed in the outer tub and configured to accommodate laundry received through the opening;
a water level sensing unit configured to sense whether a water level of the outer tub reaches a predetermined water level; and
a drainage unit configured to drain the water contained in the outer tub;
wherein the control unit is further configured to control the drainage unit to drain water contained in the outer tub based on the water level sensing unit sensing that the water level of the outer tub reaches the predetermined water level.

7. The washing machine according to claim 1 , further comprising:
an outer tub to contain water;
a rotatable tub disposed in the outer tub and configured to accommodate laundry received through the opening;
a drainage unit configured to drain the water contained in the outer tub; and
a drain input unit to receive an input for draining the water contained in the outer tub.
