Description

Den foreliggende oppfinnelse vedrører en radarsonde ifølge innledningen i krav 1. The present invention relates to a radar probe according to the introduction in claim 1.

Det er kjent å anvende radarsonder av denne type til styring av spyling av urinalskåler. Radarsonden og styreinn-retningen kan sikret mot vandaler, være anordnet bak urinalskålen. Betjening av spyleinnretningen er berøringsfri og er derved hygienisk. Radarsonden detekterer enhver bevegelse hos brukeren, noe som benyttes for å hindre spylingen. Dersom brukeren fjernet seg og det ikke lenger detekteres bevegelser, innledes spylingen. På grunn av at ventilen i armaturene også åpnes når en person tilfeldigvis går forbi armaturen, foreslås det ifølge DE-A-3.008.025 å utstyre radarsonden med to ømfint-lighetstrinn og å omkople den automatisk fra et trinn med mindre ømfintlighet til et trinn med større ømfintlighet når armaturen benyttes. It is known to use radar probes of this type to control the flushing of urinal bowls. The radar probe and the steering device can be secured against vandals and arranged behind the urinal bowl. Operation of the flushing device is touch-free and is therefore hygienic. The radar probe detects any movement by the user, which is used to prevent flushing. If the user moves away and movements are no longer detected, flushing is initiated. Due to the fact that the valve in the luminaires is also opened when a person accidentally walks past the luminaire, according to DE-A-3,008,025 it is proposed to equip the radar probe with two levels of sensitivity and to switch it automatically from a level of less sensitivity to a level of greater sensitivity when the fixture is used.

Med nevnte radarsonde foreligger imidlertid den vanske-lighet at ved hyppig benyttelse spyles det ikke, på grunn av at det stadig registreres bevegelser. Dersom en bruker ikke beveger seg i et visst tidsrom, spyles det derimot for tidlig, noe som er ubehagelig og betyr unødvendig vannforbruk. With said radar probe, however, there is the difficulty that with frequent use it is not flushed, due to the fact that movements are constantly being recorded. If a user does not move for a certain period of time, however, it is flushed too early, which is unpleasant and means unnecessary water consumption.

Formålet med oppfinnelsen er å frembringe en radarsonde av den innledningsvis angitte type hvormed disse vanskeligheter unngås. Dette er ifølge oppfinnelsen løst ved hjelp av de trekk som er angitt i den kjennetegnende del av krav 1. The purpose of the invention is to produce a radar probe of the type indicated at the outset with which these difficulties are avoided. According to the invention, this is solved by means of the features specified in the characterizing part of claim 1.

Radarsonden er retningsavfølgende, noe som betyr at den skjelner mellom en bevegelse hen mot armaturen og en bevegelse bort fra denne. The radar probe is directional, which means that it distinguishes between a movement towards the luminaire and a movement away from it.

Ved en urinalskål reagerer radarsonden på at brukeren beveger seg bort, og utløser umiddelbart en spyling. Når en bruker etter å ha beveget seg hen til urinalskålen ikke beveger seg i et lengre tidsrom, utløses det ingen spyling. Til tross for de store fordeler er det ikke nødvendig med ømfintlighets-innstilling og omkopling av ømfintlighetstrinnene. Med enkel montering oppnås det således en optimal spylekomfort og et sparsomt vannforbruk. In the case of a urinal bowl, the radar probe reacts to the user moving away, and immediately triggers a flush. When a user, after moving to the urinal bowl, does not move for an extended period of time, no flushing is triggered. Despite the great advantages, there is no need for sensitivity setting and switching of the sensitivity steps. With simple installation, optimal flushing comfort and sparing water consumption are thus achieved.

Ifølge en fordelaktig utførelsesform av oppfinnelsen er radarsonden rettet skrått oppad. I forbindelse med en urinalskål unngås derved på enkel måte utilsiktede spylinger når ventilen er utett. According to an advantageous embodiment of the invention, the radar probe is directed obliquely upwards. In connection with a urinal bowl, accidental flushing is thus easily avoided when the valve is leaking.

Ifølge en annen foretrukket utførelsesform av oppfinnelsen er radarsonden utstyrt med en i og for seg kjent horn-antantenne. Denne har fortrinnsvis innstillbar åpningsvinkel, slik at det kan tas hensyn til spesielle installasjonssitua-sjoner, f.eks. urinalskillevegger og hjørneløsninger. According to another preferred embodiment of the invention, the radar probe is equipped with a known per se horn antenna. This preferably has an adjustable opening angle, so that special installation situations can be taken into account, e.g. urinal partitions and corner solutions.

En foretrukket utførelsesform av oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning til den medfølgende tegning, hvor: Fig. 1 viser et skjematisk riss av et vertikal snitt gjennom en radarsonde som er anordnet bak en urinalskål. Fig. 2 viser et skjematisk planriss ovenfra av urinalskålen . A preferred embodiment of the invention will be described in more detail below with reference to the accompanying drawing, where: Fig. 1 shows a schematic view of a vertical section through a radar probe which is arranged behind a urinal bowl. Fig. 2 shows a schematic top view of the urinal bowl.

Umiddelbart bak en urinalskål 1 er det i en vegg anbrakt en radarsonde 5 med hornantenne for mikrobølger. Urinalskålen er gjennomtrengelig for slike mikrobølger og er for spyling av den koplet til en vannledning 3 og en avløpsledning 2. I veggen befinner det seg dessuten en enhet 4 med magnetventil og en styreinnretning som i samarbeid med radarsonden 5 bevirker automatisk spyling av urinalskålen, som regel fra en ikke vist cisterne. Immediately behind a urinal bowl 1, a radar probe 5 with a horn antenna for microwaves is placed in a wall. The urinal bowl is permeable to such microwaves and for flushing it is connected to a water line 3 and a drain line 2. In the wall there is also a unit 4 with a solenoid valve and a control device which, in cooperation with the radar probe 5, causes automatic flushing of the urinal bowl, as a rule from a cistern not shown.

Radarsonden frembringer et felt som er rettet skrått oppad under en vinkel a . The radar probe produces a field which is directed obliquely upwards at an angle a.

En persons bevegelser i dette felt 6 frembringer et ekko hvorav radarsonden kan bedømme retningen for bevegelsene. En bevegelse hen mot urinalskålen 1 skjelnes fra en bevegelse bort fra urinalskålen. Bevegelser vinkelrett på stråleretningen har overfor radarsonden hastigheten 0 og registreres ikke av denne. En person som går tilfeldig forbi urinalskålen blir derved ikke registrert og utløser heller ikke spyling. Dersom imidlertid brukeren beveger seg hen mot urinalskålen mot pilens 8 retning og kommer inne i feltet 6, registreres denne bevegelse. Like-ledes registreres en bevegelse i pilens 8 retning og oppfattes som "fjerning". Spylingen utløses umiddelbart etter at det etter en hen-bevegelse registreres en bort-bevegelse. En spyling utløses også når det samtidig med en hen-bevegelse registreres en bort-bevegelse. Dersom således en bruker beveger seg hen mot urinalskålen under spylingen, avsluttes spyle-syklusen som ellers. For at kortvarig bevegelse hen mot og bort fra urinalskålen ikke skal innlede spyling, er det anordnet en tidsforsinkelse som sikrer at det ikke utløses spyling før ut-løpet av et visst tidsrom. Etter at spylingen er begynt løper det en viss spyletid, som, nevnt ovenfor, heller ikke avbrytes når en annen bruker ankommer. A person's movements in this field 6 produce an echo from which the radar probe can judge the direction of the movements. A movement towards the urinal bowl 1 is distinguished from a movement away from the urinal bowl. Movements perpendicular to the beam direction have a speed of 0 vis-à-vis the radar probe and are not registered by it. A person who randomly walks past the urinal bowl is thereby not registered and does not trigger flushing either. If, however, the user moves towards the urinal bowl in the direction of the arrow 8 and enters the field 6, this movement is recorded. Similarly, a movement in the direction of the arrow 8 is registered and perceived as "removal". The flushing is triggered immediately after a forward movement is detected, followed by an away movement. A flush is also triggered when an away movement is detected at the same time as a forward movement. Thus, if a user moves towards the urinal bowl during flushing, the flushing cycle ends as usual. So that short-term movement towards and away from the urinal bowl does not initiate flushing, a time delay is arranged which ensures that flushing is not triggered before the end of a certain period of time. After the flushing has started, a certain flushing time runs, which, as mentioned above, is also not interrupted when another user arrives.

I risset i fig. 2 er feltet 6 virksomt under en vinkel ø på 140° og en radius på 600 mm. Denne åpningsvinkel B kan inn-stilles på hornantennen tilpasset til spesielle monteringsfor-hold, f.eks. hjørneplassering, slik at feltet i hvert tilfelle er optimalt. In the drawing in fig. 2, the field 6 is active under an angle ø of 140° and a radius of 600 mm. This opening angle B can be set on the horn antenna adapted to special mounting conditions, e.g. corner location, so that the field is optimal in each case.

Som fig. 1 viser er hornantennen rettet oppad under en vinkel a. Denne vinkel er så stor at en spylestrøm som beveger seg nedad i pilens 7 retning ikke registreres av radarsonden 5. Ved feil ved cisternen fører derved heller ikke en kontinuerlig rennende vannstrøm til utløsning av unødvendige spylinger. As fig. 1 shows, the horn antenna is directed upwards at an angle a. This angle is so large that a flushing current moving downwards in the direction of the arrow 7 is not registered by the radar probe 5. In the event of a fault at the cistern, a continuously flowing water flow does not thereby trigger unnecessary flushing .
