ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a system for delivering hot water from a water supply source to a washer machine.
BACKGROUND OF THE INVENTION
Washer machines are commonly used to wash clothing. Conventional washer machines have an inlet connector to receive hot water from a supply source such as a hot water feed-line installed in the home. In common practice, the inlet connector of the washer machine is typically connected to the hot water supply source by a flexible hose assembly having a single hose made from a synthetic polymer such as rubber. Over time the flexible hose will degrade and upon complete failure hot water flowing therein is expelled into the outside environment. In the case of a basement, leakage of hot water typically causes more of an inconvenience than damage. However, in recent years more and more washer machines are being located and used on floors which have occupied spaces below. As such, leakage of water can cause significant property damage to the floor and the occupied space below.
SUMMARY OF THE INVENTION
The principal object of the present invention is to provide a safety hose system that can be safely used to supply hot water from a hot water supply source to a washer machine.
The present invention is a safety hose system for use in delivering water from a water supply source to an inlet connector of a washing machine. In one embodiment, the system comprises a first connector engageable with the inlet connector of the washer machine and a second connector engageable with the water supply source. The system further comprises a first hose having first and seconds end connected to the first and second connectors, respectively. The system further comprises a second hose disposed concentrically and sealed about the first hose and extending from the first connector to the second connector. The system further comprises a sealing material. The first and second ends of the second hose are molded to the first and second connector, respectively, by the sealing material to form an unitary one piece structure. The system may further comprise an over-spill portion formed by said second hose being disposed about the first hose. The over-spill portion comprises a water reactive material which will change the color of any water entering into the over-spill portion. The system further comprises a third hose having a first end engaged with the second hose and in communication with the over-spill portion. The third hose is made from a transparent material such that the color of any water passing there through can be visually observed. In operation, if the first hose should become damaged any water flowing through the first hose will be passed into the over-spill portion and into the third hose where it is safely discarded.
