WATER-MIXING TAP WITH CONTACTLESS REMOTE CONTROL Russian patent published in 2005 - IPC

FIELD: technical means of water supply.

SUBSTANCE: the invention presents a water-mixing tap with contactless remote control and is pertinent to the technical means of water supply. The water-mixing tap with contactless remote control contains a body with a chamber for mixing of water and the tap-changer, feeding pipes, a discharge pipe with an outlet nozzle and an inlet-outlet head, an autonomous control-and- measuring block electrically connected with a source and a receiver of optical rays and with electromagnetic valves of water delivery. The outlet nozzle is made in the form of a centrifugal spraying injector forming a cone of finely dispersed uniformly sprayed water. The discharge pipe is made with a capability to accommodate a fiber-optical transducer with an external modulation, an outlet optical butt of which is placed in the inlet-outlet head of the discharge pipe and the opposite butt of the transducer is optically connected to the source and the receiver of the optical emission located in the autonomous control and measuring block electrically connected with the electromagnetic valves of water feeding. At that the electrical circuit of the block is made on the basis of the integrating circuit of accumulation of the signals of the measuring information. The technical result is a decrease of consumption of water and thermal energy used for its heating up, provision of the switch-on state of the tap only by availability of an object of treatment within the zone of control and at achievement of a combination of contactless of on-off turnings of the water feeding with electric passivity of the tap, its stability against action of electromagnetic interferences and origination of the false on /off switching, protection of sensing optical elements of the contactless drive of the tap against actions of vandals (versions).

EFFECT: the invention ensures a decrease of consumption of water and thermal energy used in the process, provision of the switch-on state of the tap just by availability of an object of treatment in the zone of control, protection against different types of interferences.
