Definitions

the present invention relates to a device for controlling a tap by optical detection.
Devices are known according to which the presence of the user's hands or body is detected using an opto-electronic system which triggers the flow of water, the flow being stopped by move it away from the user.
the detection device is produced by a transmitter producing, for example, an infrared ray which is reflected by the hands or the body of the user towards a receiver sensitive to the ray emitted and which then delivers a signal, the latter being amplified and processed to allow control of a solenoid valve.
the transmitter and the receiver are physically very close and the incident ray is practically reflected on itself. Therefore, the detection area is very small and it is located under the spout of the tap. Under these conditions, it is not possible to maintain the flow of water if the hands come out of this area and plunge, for example, towards the bottom of the sink.
the present invention which overcomes these drawbacks, is remarkable in that the transmitter and the receiver are separate and in that their axes are concurrent and contained in an inclined plane.
1 is a sink comprising a spout 2 for supplying water placed under the control of a detection unit 3.
the detection zone 5 extends practically from the spout 2 to the bottom of the sink.
the axes 8 and 9 are concurrent and contained in an inclined plane which lowers towards the bottom of the sink relative to the horizontal XX, the point of convergence I being located, substantially, on the vertical YY passing through the axis of the spout 2.
a lens is placed in front of the radiating semiconductor element constituting the emitter, the axis of the lens is coincident with that of said element and practically the central emerging ray, that of Figures 1 and 4 , is perpendicular to the partition supporting the device.
the central emerging ray, materialized by the axis 8, must be deflected towards the center. This result is obtained by shifting the optical axis of the lens 11 relative to that of the emitter 6. A analogous but symmetrical arrangement is adopted with regard to the receiver.
the optical axes of the transmitter and the receiver are inclined as shown in FIGS. 7 to 8.
a prism is placed in front of the lenses 11 Fresnel 12, made of a material allowing the infrared to pass through,
Fresnel 12 made of a material allowing the infrared to pass through
a plurality of prisms is used, the assembly thus constituted being able to serve as a protector for the device, the prism (s) 12 making it possible to widen the beam downwards the vertical plane.
the device which has just been described must be able to be used whatever the distances between the spout 2 and the support wall on the one hand, and said spout and the bottom of the sink on the other hand. In other words, it is necessary to be able to vary the position of the point I where the axes 8 and 9 meet, and this, preferably, along a horizontal ZZ.
each lens can be moved in a vertical direction and in a horizontal direction relative to the element in front of which it is placed.
each lens 11 is carried by a slide 13 guided in a slide 14 of the housing 15 containing the transmitter or the receiver, the axis WW of the slide being inclined relative to the plane of symmetry of the device, which contains the YY axis.
each slide allows a double adjustment.
the meeting point I of the axes 8 and 9 is in Ia, that is to say further than that I on the same horizontal ZZ.
the meeting point is in Ib, that is to say less far than that I on the same horizontal ZZ.
the invention provides for associating a usual device with that of the invention, as is apparent from FIGS. 4 and 5.
the usual device detects the zone located immediately in below the spout 2.
the usual device 16 is arranged between the transmitter 6 and the receiver 7.
