1. A washing machine comprising:
a main body;
a tub disposed in the main body; and
a detergent supply device configured to supply a detergent to the tub and to receive water introduced from a water supply source at a position lower than a level of the detergent in the detergent supply device, the water supply source being an external water supply source, and
the detergent supply device further comprises:
a detergent container configured to contain the detergent;
a housing comprising a water supply part to receive water from the external water supply source, and configured to guide the water received through the water supply part to the detergent container; and
a housing cover comprising a detergent container hole to receive the detergent container, and configured to cover an open upper side of the housing,
an inlet through which the water is introduced from an outside of the detergent supply device;
a first outlet configured to delay discharge of detergent injected into the detergent supply device to the outside of the detergent supply device so that a time taken to discharge the detergent is increased; and
a second outlet configured to discharge the detergent injected into the detergent supply device and the water introduced into the detergent supply device through the inlet,
wherein the first outlet is formed below the second outlet so that the detergent injected into the detergent supply device which is not discharged by the second outlet is discharged by the first outlet, and residual water inside the detergent supply device is discharged to the outside of the detergent supply device.
