Abstract: A detergent supply apparatus of a washing machine, which prevents water, which is not discharged from a detergent tub through a siphon unit, from overflowing the detergent tub and being discharged to the outside of the washing machine. The siphon unit includes a siphon pipe formed on a bottom of a chamber of the detergent supply apparatus, and a cover member installed above the siphon pipe. The cover member includes a siphon cap surrounding an outer circumferential surface of the siphon pipe so that a siphon channel is provided between the siphon pipe and the siphon cap, and a bypass channel for circulating water overflowing the siphon channel to the siphon channel.
