ABSTRACT:
The self cleaning rain gutter system of this invention has the quadruple advantage of being easy to install, being clog resistant, being self cleaning, and being without visible slope. Ease of installation is accomplished by modular sections made up of box, gutter and louver rack. These are simply installed level, using the fascia board as a guide as well as a support. A modular section may be installed fully assembled, with preset slope and leader funnel with cleaning water connections--or, at the option of the installer, may be mounted in a two step procedure, first the support box and then the gutter and louver rack. Clog resistance is provided by an integral top grating which interdicts most leaves and twigs as well as the occasional tennis ball. These larger items tend to provide the framework for clogs. The smooth rounded cross section of the bottom of the inner gutter also tends to resist clogging. Self cleaning is accomplished by a system of water channels and dislodging jet nozzles and at least one flow making jet nozzle. When the self-cleaning feature is activated, either manually or automatically, jets of water into the gutter to dislodge and float away to the next down spout whatever small debris have passed through the top louvers. Water to activate the self-cleaning feature may be obtained by connecting a hose and manually opening a valve, or may be automatically obtained by means of either a timer or a rain sensor and electronically controlled valve.
