Definitions

  • the present invention relates to a scattered light smoke detector with an optical measuring chamber, which has a sensor arrangement with at least one light source and a light receiver and a labyrinth system with arranged on the periphery of the measuring chamber aperture, wherein the at least one light source and the light receiver are each arranged in a housing.
  • the optical measuring chamber is designed such that disturbing ambient light can not and smoke very easily penetrate into it.
  • the at least one light source and the light receiver are arranged so that no light rays can pass directly from the at least one light source to the receiver. In the presence of smoke particles in the beam path, the light of the at least one light source is scattered to this and a portion of this scattered light is incident on the light receiver and causes an electrical signal.
  • the invention should now be a scattered light smoke detector of the type mentioned above, in which the light-penetrated optical surfaces, as little as possible dirty, so that the detector has a constant sensitivity.
  • the said housing have an elongated shape and have a small window opening, and that the at least one light source and the light receiver are arranged in the rear part of their housing, so that between the window openings of the housing and the light penetrated optical surfaces of the at least one light source and / or the light receiver, a relatively large distance is formed.
  • a further advantage of the arrangement according to the invention is that the respective bundles of rays have a relatively small cross section, so that the scattered light reaching the light receiver is obtained with high certainty from smoke particles in the center of the measuring chamber and not from dust particles deposited on its bottom.
  • the inventive smoke detector is characterized in that said distance is greater than the diameter of said optical surfaces.
  • the smoke detector according to the invention is further characterized in that the measuring chamber is bounded above by a carrier disk from which said housing project downwards, and that the labyrinth system forms a lid-like, fixable on the carrier disk and having a bottom and a side wall component, which can be plugged from below onto the carrier disk.
  • a first preferred embodiment of the inventive smoke detector is characterized in that at least one of the window openings of said housing is enclosed by a one-piece frame, and in that said casings are open at the bottom, with the exception of the window openings, and in that the bottom of said component has covers for the casings.
  • a compact, free scattering space is formed in the measuring chamber between the light exit or light entry side of the housing and the opposing diaphragms.
  • a further preferred embodiment of the inventive smoke detector is characterized in that a contact strip for the electrical connection of the detector with a provided in a detector base connector strip is arranged on the support disk, and that said electrical connection is effected by a tangential movement of the contact strip and / or connector strip.
  • the contact strip is integrated on the upper side of the carrier disk in so-called insert technique.
  • FIG. 2 shows a view of a part of the optical sensor system 2 in a cross section through the detector as seen from below.
  • the base 1 is intended for mounting on the ceiling of the room to be monitored, with the installation either directly on a flush box or surface-mounted with or without base addition.
  • the base 1, which essentially consists of a circular plate and a downwardly projecting edge web, contains inter alia a plug connector 4 (FIGS. 3, 4) which is provided for receiving a contact strip 5 (FIG. 4) connected to the sensor system ,
  • the optical sensor system 2 includes a plate-shaped carrier 6 for the optical sensor, a fixed to the underside of the carrier 6 lid-shaped labyrinth 7, arranged on the base 1 facing the upper side of the carrier 6 arranged circuit board 8 with the transmitter and a printed circuit board 8 am Edge and upwardly covering cover 9, which forms part of the housing 3.
  • the contact strip 5 is an integral part of the support plate 6 and protrudes from this upwards.
  • the cover 9 has substantially the shape of a plate with a peripheral collar at the edge and with an opening 10 for the passage of the contact strip 5, so that this projects into the plane of the socket 1 arranged in the socket strip 4.
  • the optical sensor shown in FIG. 2 includes a measuring chamber formed by the carrier 6 and the labyrinth 7 with a light receiver 11 and two light sources 12, 12 ', which are each arranged in a housing 13, 14, 15.
  • These housings consist of a bottom part, in which the respective diode (photodiode or IRED) is held, and which has a window opening for the entrance or exit of light at its front side facing the center of the measuring chamber.
  • the scattering space formed in the measuring chamber in the region in front of the mentioned window-like openings of the housings 13, 14, 15 is compact and exposed.
  • This arrangement and shape makes the detector for the use of a usable in this scattering space transparent body for smoke simulation best suited.
  • Such transparent bodies are used to adjust or test for smoke sensitivity in the manufacture of the detectors (see EP-B-0 658 264).
  • the frames of the window openings are integrally formed at least in the housings 14 and 15, whereby the tolerances for the smoke sensitivity are reduced.
  • the window frames consist of two parts, one of which is worked on the ceiling and the other at the bottom of the measuring chamber.
  • the windows are rectangular or square and between the window openings and the associated light source 12, 12 'and the lens of the associated light receiver 11 is a relatively large distance, resulting in a relatively small opening angle of the respective light beams.
  • a small opening angle of the light beams has the advantage that, on the one hand, hardly any light of the light sources 12, 12 'hits the ground and, on the other hand, the light receiver 11 does not "see” the ground, so that dust particles deposited on the floor can not generate disturbing scattered light.
  • Another advantage of the large distance between the windows and the light source 12, 12 'and the lens of the light receiver 11 is that the light-penetrated optical surfaces are relatively deep inside the housing and are thus well protected against contamination, resulting in a constant sensitivity the opto-electronic elements result.
  • the labyrinth 7 consists of a bottom and peripherally arranged aperture 16 and it contains flat cover for said housing 13, 14, 15.
  • the bottom and the panels 16 serve to shield the measuring chamber against extraneous light from the outside and to suppress the so-called background light ( see also EP-A-0 821 330 and EP-A-1 087 352).
  • the peripherally arranged aperture 16 each consist of two legs and have an L-shaped configuration. Due to the shape and arrangement of the aperture 16, in particular by their mutual distance, it is ensured that the measuring chamber is adequately shielded from extraneous light and still their function can be checked with an optical test device (EP-B-0 636 266).
  • the panels 16 are arranged asymmetrically, so that smoke from all directions can penetrate similarly well into the measuring chamber.
  • the directed against the measuring chamber leading edge of the aperture 16 is formed as sharp as possible, so that only a little light fall on such an edge and can be reflected.
  • the arrangement of the two light sources 12 and 12 ' is selected so that the optical axis of the light receiver 11 with the optical axis of the one light source, according to the light source 12, a blunt and with the optical axis of the other light source, according to the light source 12', includes an acute angle.
  • the light of the light source 12, 12 ' is scattered by penetrating into the measuring chamber smoke and a portion of this scattered light is incident on the light receiver 11, wherein at an obtuse angle between the optical axes of light source and light receiver of forward scattering and at an acute angle between the optical axes of backward scattering speaks.
  • the carrier 6 is prepared accordingly and has provided in the housings 13, 14 and 15 grooves (not shown) in which polarizing filter can be fixed.
  • polarizing filter can be fixed.
  • light sources 12, 12 'diodes can be used, which emit radiation in the wavelength range of visible light (see EP-A-0 926 646), or the light sources can emit radiation of different wavelengths, for example the one light source red and the other blue light.
  • the housing 3 of the smoke detector is constructed substantially in two parts and consists of the already mentioned cover 9 and a sensor sensor system 2 comprehensive detector hood 17.
  • the latter consists of an upper annular portion and a spaced therefrom, the tip of the detector forming plate which is connected to the upper annular part by arcuate or rib-like webs 18.
  • the space designated by the reference numeral 19 between the upper and the lower part of the detector hood 17 forms a running over the entire housing circumference opening for the entry of air and thus smoke to the optical sensor system 2, said opening is interrupted only by the relatively narrow webs 18 , There is an even number of webs 18 is provided, according to four.
  • the detector hood 17 and the cover 9 are fixed to the carrier 6 via hook-type snap fasteners (not shown) and the entire detector is fastened in the base 1.
  • a ring 20 is inserted, which carries an insect screen 21 made of a suitable flexible material.
  • the carrier 6 is pressed against the ring 20, whereby the insect screen 21 is fixed in the detector.
  • the attachment of the detector in the base 1 is done by a kind of bayonet lock.
  • the detector is from below pushed into the base 1, which is possible due to a formed by guide ribs and guide grooves mechanical coding only in a single relative position between the detector and socket. Then, the detector in the base 1 is rotated by an angle of about 20 ° (Fig.
  • the contact strip 5 is integrated on the upper side of the carrier 6 in so-called insert technique and manufactured in one piece with the carrier 6.
  • the electrical connections are made to a cast in the carrier 6 stamped part with metallic, mutually insulated metal parts.
  • the free ends of these Metailleiter protrude next to the contact strip 5 from the support 6 and form contact points for the production of solder joints to the transmitter on the circuit board. 8
  • a light guide 22 is fixed to the bottom of the labyrinth 7 forming member, which projects on the one hand up to the circuit board 8 and on the other hand through a hole in the lower part of the detector hood 17 from the detector hood.
  • the detector hood is provided in the region of said bore with a spherical recess 23 which surrounds the free end of the light guide 22.
  • the light guide 22 serves as a so-called alarm indicator for the visual display of alarm conditions of the detector.
  • an LED (not shown) is provided for this purpose, which is activated in an alarm condition and the light guide 22 is exposed to light.
  • the alarm indicator requires little power and, because it is located in the area of the detector apex, it is practically visible on all sides. The visibility from all sides is only given from a viewing angle of 20 ° to the horizontal, but since the detector is mounted on the ceiling, this condition is met in most cases.
  • the light guide 22 is guided through the measuring chamber in the area between the housings 14 and 15.
  • the two housings 14 and 15 are connected to each other at their front side and thus form with their inner side surfaces and the connecting surface between them one the light guide 22 surrounding wall, which largely shields the scattering space of the measuring chamber against the light guide 22.
  • the smoke detector described so far is a purely optical detector with smoke detection based on the scattered light caused by smoke particles that have penetrated into the measuring chamber.
  • the detector can be designed as a two-criteria detector and additionally contain a temperature sensor.
  • two temperature sensors 24 formed by NTC resistors are provided, which are arranged in the region of two mutually opposite webs 18.
  • the webs 18 have in the middle of an elongated recess 25, in which from above the temperature sensors 24 protrude, which are mounted on the circuit board 8.
  • Optical thermal detectors are known, so that a description of the signal evaluation is omitted here.
  • the detector could contain other sensors, such as a fire gas sensor (CO, NO x ), which could be arranged at correspondingly small dimensions within the measuring chamber.
  • CO, NO x fire gas sensor
  • optical, optical-thermal and thermal fire detectors are in use today, whereby gas detectors can still be used for these.
  • the optical, thermal and optical thermal detectors may additionally have a fire gas sensor.
  • the detector shown covers the variants visually and optically-thermally (possibly supplemented by a fire gas sensor) from, of course, in the purely optical detector no temperature sensors 24 are provided. Apart from that, but the detector structure in the two variants previously described mechanically completely the same. By using a double photodiode as the light receiver 11, optimum redundancy (two light transmitters, two light receivers, two temperature sensors) can be achieved.
