To provide a device for easily washing a dish basket by naturally draining water which is stored in a conventional dish basket so as to keep the inner part of the dish basket sanitary.

A fan shape inclination is obtained with a drain outlet as a center on the whole bottom surface of the dish basket as shown in a dish basket body (Figure 2). Then water falling onto the dish basket through the drain outlet (2) is naturally drained through a drain hose. When a drain outlet stopper (4) is inserted to the inner part of the drain outlet (2). Then tap water is fed from a faucet and stored in the dish basket so as to wash the basket as shown in Figure 1. When tap water is fed from the faucet, a funnel receiver (1) is attached to the tip end of the hose, so that water is easily supplied from any type of faucet and fed into the dish basket from a water supply port (3).
