Patent ID: 8887536

Claim:
A washing/drying machine having a fragrance supply apparatus comprising: a washing/drying machine body to collect clothes to be treated; and a fragrance supply apparatus to supply a fragrance solution contained therein into the clothes due to a pressure difference, the fragrance supply apparatus comprising: a fragrance solution container to contain the fragrance solution therein; a dock to which the fragrance solution container is connected, and having a fragrance solution outlet disposed below the fragrance solution container and an air inlet formed at an upper side of the fragrance solution outlet, wherein the air inlet is formed at a position where the pressure difference is generated to effuse the fragrance solution through the fragrance solution outlet; an opening and closing unit to open and close the air inlet, and a controller to control the opening and closing unit, wherein the fragrance solution container comprises: a container main body having a cylindrical shape for containing the fragrance solution therein, wherein the container main body is provided with an injection hole disposed at an upper end of the container main body for injecting the fragrance solution into the fragrance main body therethrough and a coupling unit formed a lower end of the container main body to be cut down in a radial direction of the container main body, a mount member coupled to the coupling portion of the container main body to be communicated with each other, wherein the mount member is provided with a dock coupling portion inwardly reduced in a radial direction and downwardly extended and having a discharge hole formed a central portion of the dock coupling portion, and a blocking member movably disposed in the mount member in a vertical direction to block the discharge hole of the mount member by its own weight when fragrance solution container is separated from the dock, wherein the dock comprises an opening operation portion to come in contact with the blocking member to upwardly move the blocking member, thus to open the discharge hole, the opening operation portion is upwardly protruded from an inner lower surface of the dock to be inserted into the discharge hole, wherein the pressure difference is generated while the air inlet is opened by the opening and closing unit so that the fragrance solution is dropped through the fragrance solution outlet, and wherein the supply of the fragrance solution is stopped while the air inlet is closed by the opening and closing unit.
