PURPOSE: A pump device for liquid deter is provided to form main components of first and second valve units through a molded material. CONSTITUTION: An inlet(16) for the inflow of a liquid detergent is formed at a housing(10), and the housing stores the liquid detergent in an inner space(12). An internal pipe path(52) connected to the inner space of the housing is installed at a moving pipe path unit(40). The moving pipe path unit reciprocates along the inner space of the housing. Through the connection with and movement of the moving pipe path unit, a first valve unit(20) opens/closes the inlet and a second valve unit(60) opens/closes the internal pipe path. |
