Washing machine with water storage tank

摘要

A washing machine comprises a tub in which a drum is rotatably mounted, and a storage tank having a flow connection to the tub via a feeding line provided with a discharge pump and a three-port valve adapted to drive the flow to a drain or to the storage tank, rinsing fluid being stored in the storage tank for subsequent reuse. The washing machine further comprises an automatic valve connected to a drain line downstream the three-port valve and to an overflow line downstream the storage tank, said automatic valve being provided with means for avoiding any mixture of flows in the different configurations of the washing machine cycles.

1. A washing machine comprising:
a tub; a drum rotatably mounted within the tub; a storage tank having a flow connection to the tub via a feeding line; a discharge pump; a first valve selectively coupling the discharge pump to a drain or the storage tank; a drain line fluidly coupling the first valve with the drain; an overflow line fluidly coupling the storage tank to the drain; and a second valve fluidly coupled with the drain line downstream of the first valve and with the overflow line downstream of the storage tank, said second valve adapted to avoid mixing a flow of liquid between the drain line and the overflow line during a washing machine cycle; wherein the second valve is a four-port valve.
