ABSTRACT:
An automatic faucet assembly includes a chassis and a cover removably connected to the chassis, wherein both chassis and cover extend above the surface of a deck of a sink basin. The chassis has a mounting section for mounting the chassis to the surface of the deck. A deck plate is mounted between the mounting section and the surface to provide support and stability to the faucet assembly. The faucet assembly further comprises: a fluid conduit extending through the chassis and connecting a fluid discharge port with a fluid supply; an infrared sensor mounted on the chassis for sensing the presence of a user of the faucet assembly; an electrical connector wire extending from the infrared sensor, through an opening in the deck, to a solenoid valve that turns on the fluid supply when infrared sensor senses the presence of the user; and a battery-operated power supply for supplying power to the infrared sensor. The cover connects with the chassis, providing a sealed chamber for the fluid conduit, infrared sensor, electrical connector wire, and power supply. Upon connection of the cover and chassis, a mechanical microswitch is activated by a switch actuator extending from the cover, enabling the power supply to energize the infrared sensor. Cover and deck plate each comprises a zinc die cast layer formed in the shape of the cover and the deck plate, respectively, a metallic polyester layer formed on the zinc die cast layer, and a substantially clear, polymer layer formed on the metallic polyester layer.
