Title: WATER-SAVING WASHING MACHINE
Abstract:
Disclosed is a water-saving washing machine comprising an ordinary washing machine (1) and a water-saving device (2). The water-saving device (2) comprises a water-saving drum (3), a water-recovery electromagnetic valve (4), a water-recovery water pump (5), a water circulating pump (6), a water-saving drum upper water level switch (7) and a water-saving drum lower water level switch (14), wherein the water-recovery water pump (5) is in communication with a water drainage port of a water drainage electromagnetic valve (9) of the ordinary washing machine (1), the water-recovery electromagnetic valve (4) is in communication with the water drainage port of the water drainage electromagnetic valve (9), the water-recovery electromagnetic valve (4) is connected to a water drainage pipe (10), and a water outlet of the water-recovery water pump (5) is in communication with the water-saving drum (3). A water outlet of the water circulating pump (6) is located at a position at the top of a water-holding drum (11), a water-drawing port of the circulating pump (6) is located at the bottom of the water-saving drum (3), the water-saving drum water level switch (7) is placed at an upper portion of the water-saving drum (3), the water-saving drum lower water level switch (14) is placed at a bottom plate of the water-saving drum (3), a controller (13) is used to control the water-recovery water pump (5) to recover the water used in the final rinse by the washing machine and draw same into the water-saving drum (3), and when washing clothes the next time, the controller (13) is used to control the water circulating pump (6) to draw the recovered water from the water-saving drum (3) into the water-holding drum (11) for use in the first washing cycle, thereby saving limited water resources.
