PROBLEM TO BE SOLVED: To frequently perform accurate washing by reducing drainage in the water piping in a beverage supply device. SOLUTION: A circulation path where washing liquid can circulate through a reserver 2 and water piping 12 without passing through a hot water tank 6 is formed by providing a switching valve 14 in a water supply port 7, and providing a circulation line 15 communicating with the switching valve 14. Thus, it is possible to perform washing with small amounts of washing liquid, and to frequently perform washing since a waster liquid container 13 is hardly full. Also, it is possible to increase the peeling effects of dirt in the reserver 2 and the water piping 12, and to perform accurate washing by making the washing liquid circulate and flow.
