Safety device against fluid leakage for household appliances

Abstract

A safety device against fluid leakage for a domestic appliance, arranged for connection between a fluid source and the domestic appliance, comprising: a first conduit (23) and a second conduit respectively defining a first conduit (23) for fluid A connecting body (20) and a second connecting body (13), a fluid-tight flexible inner hose (17) and a flexible outer hose (16). The inner hose (17) is connected in fluid communication with the first conduit (23) and the second conduit (93) and extends longitudinally within the outer hose (16) such that a gap (18) having proximal and distal ends is defined at Between at least a portion of the two hoses (16, 17), a gap (18) is substantially closed at said ends for retaining possible leaking fluid therein. The device includes a first sealing means (40) operatively disposed between the outer hose (16) and the first connecting body (20) and defining a gap for the gap (18) and the first connecting body (20) The fluid communication of the chamber (30) connects the connecting passages (44-45).

Description

technical field [0001] The present invention relates to a safety device against fluid leakage, in particular an anti-overflow safety device designed for connection between a source of fluid and a device using said fluid, such as a household appliance. [0002] More specifically, the invention relates to said security devices of the type comprising: [0003] first and second connectors defining first and second conduits for fluid, respectively; [0004] Fluid-tight inner flexible hose and outer flexible hose, [0005] wherein the inner hose is connected in fluid communication with the first conduit and the second conduit and extends longitudinally within the outer hose such that a gap is defined between at least a portion of the two hoses, the gap has a proximal end and a distal end, the gap is approximately It is closed at the ends for keeping any possible leaking fluid inside. Background technique [0006] Safety devices for household appliances of the type mentioned are...

Problems solved by technology

For this purpose, in fact, a sealing element must be provided between the outer surface of the outer hose and the corresponding passage of the housing; in order to keep this sealing element in place, suitable positioning and / or fixing means must be provided, which are configured as additional component or together with the housing in a single piece, complicating the manufacture of the device and increasing its size

[0011] For example, to check the integrity of the seals of the outer hoses or gaps, testing of these devices can only be performed when the device has been almost completely assembled, and this situation complicates possible interventions in the product to correct malfunctions
