Apparatus installed in a shower for supplying functional chemicals installed in a shower

摘要

The present invention relates to a washing machine comprising a housing member; An inlet for supplying fluid to the interior of the housing member and an outlet for discharging the fluid to the outside of the housing member; And a valve unit installed inside the housing member, wherein the valve unit includes a base portion filled with a functional material therein, an inlet portion defining a passage through which the fluid flows into the base portion, A storage unit having a fastening portion formed on the housing; And a coupling part having a base part coupled with a part of the coupling part and an outflow part forming a passage through which the fluid flows out of the storage part and having a bend at a lower part of the outflow part so as to be spaced apart from an inner lower end part of the housing part Wherein the valve unit is opened by a differential pressure of fluid generated when the fluid flows along the vertical direction of the housing member while passing through the bent portion along the inner lower end of the housing member during the supply of the fluid, And the valve unit is closed as the differential pressure of fluid is released at the time of release of the functional material. Accordingly, the functional material can be reduced in manufacturing cost while appropriately controlling the dissolution of the saturated solution in which the functional material is dissolved have.
