ANTI-FLOODING SAFETY DEVICE FOR HOUSEHOLD APPLIANCES, IN PARTICULAR WASHING MACHINES

摘要

An anti-flooding safety device for a user apparatus includes:
a first connection body defining a first duct, the first duct having an inlet and an outlet, the inlet of the first duct being provided for connection to a supply point of a mains supply. An inner flexible hose and an outer flexible hose are impermeable to water, wherein the inner hose has a proximal end, which is sealingly fixed in a position corresponding to the outlet of the first duct, and a distal end for connection to the user apparatus, and wherein the inner hose extends longitudinally within the outer hose so that between at least part of the two hoses a gap is defined designed to convey to the user apparatus and/or to withhold inside it any possible leaking water. A valve arrangement on the first connection body can be switched from a position of opening of the first duct to a position of closing of the first duct following upon detection of a leakage of water. The axis of the inlet extends in a direction transverse to the axis of the outlet.

1. An anti-flooding safety device for a user apparatus, in particular a household appliance, designed for connection between a supply point of a mains water supply and the user apparatus, said device comprising:
at least one first connection body defining a first duct for the water, the first duct having an inlet and an outlet which extend according to respective longitudinal axes, the inlet of the first duct being provided for connection to the supply point the mains supply; an inner flexible hose and an outer flexible hose impermeable to water, wherein the inner flexible hose has a proximal end, which is sealingly fixed at the outlet the first duct, and a distal end, which is provided for fluid connection to the user apparatus, and wherein the inner flexible hose extends longitudinally within the outer flexible hose so that defined between at least part of the two flexible hoses is a gap designed to convey towards the user apparatus and/or to withhold inside it any possible leaking water; and a valve arrangement mounted on the first connection body and comprising an open/close member, designed to pass from a position of opening of the first duct to a position of closing of the first duct following upon detection of a leakage of water, wherein the axis of said inlet extends in a direction transverse to the axis of said outlet.
