A steam supplying apparatus in a washing machine which is capable of supplying steam into a wash tub at the top of the wash tub, along with wash water supplied into the wash tub. The steam supplying apparatus includes a tank connected to a water supply unit adapted to supply wash water, the tank being connected with a wash tub via a steam supply line, and provided with a heater, an air chamber defined in the tank above a predetermined water level limit of the tank, the air chamber being reduced in volume in accordance with an increase in the water level of the tank, thereby causing air existing in the air chamber to be compressed, and an extension passage extending between the predetermined water level limit of the tank and the steam supply line. When water is excessively supplied into the tank over the predetermined water level limit, the excessive amount of water is drained through the extension passage and steam supply line in accordance with air pressure in the air chamber. Accordingly, it is possible to control the water level of the tank.
