Liq. dispensing equipment for shower head - has solenoid valve controlled by proximity switch monitoring area below water outlet

摘要

The equipment dispenses liquids from an shower head, having a solenoid valve (20, 22) in the passage (16, 17) to the outlet (18). The valve is controlled by a proximity switch (26, 27) in conjunction with control switchgear. The proximity switch monitors the area below the spout (18), and functions when an article is brought into this area causing the solenoid valve to open. The equipment can be used to control a shower with mixing valves (11, 12) for hot and cold water, thus avoiding the need for readjusting the valves each time the shower is used. The proximity switch can comprise a sender (26) and a receiver (27), mounted above the spout and to the side of it on a bracket (25) attached to the spout pipe.
