A convenient and effective detergent dispensing controller; one end of a main channel is a water inlet (101), and the other end of the main channel is an outlet (102) connected to the liquid inlet of a washtub; the detergent dispensing controller is provided with a valve A (2), a valve B (3), a valve C (4), a valve D (5), a pump (6) and nozzles (7); the inlet of valve A communicates with the bypass orifice A (a) of the main channel; the inlet of valve B communicates with the liquid storage tank of the detergent A; the outlets of valve A and valve B communicate with the inlet of valve C; the inlet of valve D communicates with the liquid storage tank of a detergent B; the outlets of valve C and valve D communicate with the inlet of the pump; the outlet of the pump communicates with the bypass orifice B (b) of the main channel; the bypass orifice A of the main channel is relatively adjacent to the inlet of the main channel; the bypass orifice B is relatively adjacent to the outlet of the main channel; the nozzles are connected to the main channel in tandem, and are located between the bypass orifice A and the bypass orifice B. The present invention is suitable for detergent dispensing of an electric washing device. |
