Opfindelsen angår en forsi nkelsesindretning med en forsinkelsesafbryder, som har en håndbetjent afbryder og en af et styreelement med tidselement styret elektronisk afbryder, hvorved to forbrugere, som er anbragt i adskilte grene af en strømkreds, ved slutning af den håndbe-5 tjente afbryder indkobler samtidig, og den første forbruger straks udkobl es ved brydning af den håndbetjente afbryder, og den anden forbruger udkobler tidsmæssigt forsinket ved hjælp af et styreelement og en elektronisk afbryder.BACKGROUND OF THE INVENTION The invention relates to a delay device having a delay switch having a hand operated switch and one of a control element with a time controlled electronic switch, whereby two consumers located in separate branches of a circuit at the end of the hand operated switch simultaneously switch on , and the first consumer is immediately disconnected by breaking the hand-operated switch, and the second consumer temporarily switches off by means of a control element and an electronic switch.
Sådanne forsinkelsesindretninger med en afbryder er kendte. I den-10 ne forbindelse er to forbrugere, fx. en lampe og en motor til drift af en ventilator, parallelkoblet. I lampens gren er der anbragt en håndbetjent afbryder og i motorens gren en af et styreelement styret afbryder. Denne afbryder kan være en triac, med hvis gate styreelementets styreudgang står i forbindelse. Et udtag i lampegrenen mellem en hånd-15 betjent afbryder og lampen står i forbindelse med en første forbindelsesklemme i styreelementet, som indeholder et forsinkelseskredsløb, fx. et RC-led. Den anden forbindelsesklemme i styreelementet er forbundet med nullederen. Til sådanne kendte forsinkelsesindretninger skal der i alt anbringes fire tilslutningskabler, forbindelseskabler til lampe og 20 motor, fase og nulleder, på forsinkelseskontakten i en indbygget stikdåse.Such delay devices with a switch are known. In this connection, two consumers, e.g. a lamp and a motor for operating a fan, connected in parallel. In the branch of the lamp is a hand operated switch and in the branch of the motor a switch controlled by a control element. This switch may be a triac with which the gate control element control output is connected. An outlet in the lamp branch between a hand operated switch and the lamp communicates with a first connection terminal of the control element which contains a delay circuit, e.g. an RC joint. The second connection terminal of the control element is connected to the neutral conductor. For such known delay devices, a total of four connecting cables, connecting cables for lamp and 20 motor, phase and neutral conductor, must be placed on the delay contact in a built-in socket.
Når en håndbetjent afbryder på en sådan forsinkelsesafbryder sluttes, indkobler lampen. Samtidig kommer der en spænding på den første forbindelsesklemme i styreelementet, som straks afgiver et signal til 25 sin styreudgang, og triac'en kobler ind. Derved starter motoren straks.When a hand operated switch on such a delay switch is closed, the lamp switches on. At the same time, a voltage is applied to the first terminal of the control element, which immediately gives a signal to its control output and the triac switches on. This will start the engine immediately.
Når den håndbetjente afbryder brydes, udkobler lampen straks. Styreelementets første forbindelsesklemme ligger da på nulspænding. Nulsignalet kommer derpå også forsinket af et tidselement på styreudgangen, og triac'en spærrer i motorgrenen. Tidselementet i styreelementet 30 bestemmer tidsrummet mellem udkobling af lampen og udkobling af motoren.When the hand-operated switch is broken, the lamp switches off immediately. The first connection terminal of the control element is then at zero voltage. The zero signal is then also delayed by a timing element on the control output, and the triac locks in the motor branch. The time element in the control element 30 determines the time between switching off the lamp and switching off the motor.
Triac'en i sådanne kendte forsinkelsesafbrydere styres under hele motorens funktionstid. Belastningen og dermed triac’ens samt styreelementets støjfølsomhed er derved stor. På grund af den store belastning 35 har man til triac'en brug for en kølevinge til bortledning af varme, - 2 -The triac in such known delay switches is controlled during the entire engine operating time. The noise and thus the noise sensitivity of the triac and the control element are thereby large. Due to the large load 35, a heat sink is needed for the triac to dissipate heat, - 2 -
DK 164428 BDK 164428 B
som opstår under den lange driftstid. Denne kølevinge behøver ekstra plads i det i og for sig lille kontakthus.which occurs during the long operating time. This cooling wing needs extra space in the small contact housing in itself.
Hvis den meget belastede triac skulle være defekt, kan motoren ved en sådan forsinkelsesafbryder ikke længere udkobles. Kun lampen kan 5 stadigvæk tages i brug.If the highly loaded triac should be defective, the motor can no longer be switched off at such a delay switch. Only the lamp 5 can still be used.
Til grund for opfindelsen ligger den opgave at udvikle en forsinkelsesindretning, hvis komponenter kan anbringes pladsbesparende, især ved en forsinkelsesafbryder, som kan anvendes i en almindelig indbygget stikdåse.The object of the invention is to develop a delay device, the components of which can be placed space-saving, especially by a delay switch which can be used in a standard built-in socket.
10 Denne opgave løses ifølge opfindelsen ved, - at den håndbetjente afbryder har en første mekanisk afbryder i den første forbrugers gren og mekanisk koblet med denne en anden, i samme retning koblende mekanisk afbryder i den anden forbrugers gren, 15 - at den elektroniske afbryder er anbragt som en shunt parallelt med den anden mekaniske afbryder, og - at styreelementet med sine tilslutninger er tilsluttet parallelt med den første mekaniske afbryder, og at styreelementets styreudgang står i forbindelse med den elektroniske afbryders koblingsindgang, 20 hvorhos styreelementets styreudgang ved et spændingsfald på belastningssiden af tilslutningen skifter til IND og derpå igen kobler til UD efter et fast, af et tidselement bestemt tidsrum.This task is solved according to the invention in that - the hand-operated switch has a first mechanical switch in the branch of the first consumer and mechanically coupled therewith a second, similarly coupling mechanical switch in the branch of the second consumer, 15 - the electronic switch is arranged as a shunt parallel to the second mechanical switch, and - the control element with its connections is connected in parallel with the first mechanical switch, and the control output of the control element is connected to the switching input of the electronic switch, the control output of the control element at a voltage drop on the load side of the the connection switches to IND and then switches back to OUT after a fixed period of time element.
Ved forsinkelsesindretningen ifølge opfindelsen er begge forbruge-25 re, fx. en lampe og en motor til en ventilator, ved forsinkelsesafbryderens lukkede håndbetjente afbryder via mekaniske afbrydere tilsluttet samme spænding på nettet, og på begge tilslutninger til det parallelt med den første mekaniske afbryder ligger det samme potentiale. Styreelementet registrerer spændingsfald på belastningssiden af tilslutnin-30 gen, som er forbundet med et udtag mellem den første mekaniske afbryder og lampen. Styreelementet aktiveres altså ved brydning af den håndbetjente afbryder og afgiver derpå straks et signal til sin styreudgang. . Dette signal sendes til koblingsindgangen på den elektroniske afbryder, fx. en triac, som derpå danner en shunt parallelt med den anden mekani-35 ske afbryder. Dette styresignal opretholdes i et af et RC-led i styre- - 3 -In the delay device according to the invention, both consumers, e.g. a lamp and motor for a fan, at the closed circuit breaker of the delay switch, via mechanical switches connected to the same voltage on the grid, and on both connections to the parallel to the first mechanical switch, the same potential lies. The control element detects voltage drop on the load side of the connection, which is connected to an outlet between the first mechanical switch and the lamp. The control element is thus activated by breaking the hand-operated switch and then immediately gives a signal to its control output. . This signal is sent to the switching input of the electronic switch, e.g. a triac which then forms a shunt parallel to the second mechanical switch. This control signal is maintained in one of an RC link in the control - 3 -

elementet bestemt tidsrum, således at triac'en, som blev ledende ved brydning af den håndbetjente afbryder, igen spærrer efter dette på forhånd valgte tidsrum. Følgelig er motoren stadigvæk i gang efter udkob-• ling af lampen i et af tidselementet bestemt tidsrum.the element determined for a period of time so that the triac, which became conductive upon breaking the hand-operated switch, again blocks after this preset time. Accordingly, the engine is still operating after switching off the lamp for a period of time determined by the time element.
5 Med denne forsinkelsesindretning opnås den fordel, at den elektroniske afbryder, triac'en, kun er indkoblet i motorens forsinkelsestid. Motoren forsynes ved sluttet håndbetjent afbryder via den anden mekaniske afbryder og først efter brydning af den håndbetjente afbryder i forsinkelsestiden via den parallelt koblede triac. Forsinkelsesafbryde-10 ren skånes derfor, således at den er driftsklar længere end de på markedet værende afbrydere. De elektroniske komponenter belastes altså mindre. Endvidere er det væsentligt, at motoren kan anvendes selv ved en defekt i disse komponenter.5 With this delay device, the advantage is obtained that the electronic switch, the triac, is only switched on during the motor delay time. The motor is powered by a closed hand operated switch via the second mechanical switch and only after breaking the hand operated switch during the delay time via the parallel triac. The delay switch 10 is therefore spared so that it is ready for operation longer than the switches on the market. The electronic components are thus charged less. Furthermore, it is essential that the engine can be used even if there is a defect in these components.
Som følge af triac'ens kortere driftstider behøves der ingen køle-15 vinge, hvorfor forsinkelsesafbryderen kan dimensioneres mindre. Triac'ens kortere indkoblingstider formindsker også eventuelle defekter.Due to the shorter operating times of the triac, no cooling vanes are needed, so the delay switch can be sized smaller. The triac's shorter switch-on times also reduce any defects.
Endvidere opnås der med forsinkelsesafbryderen ifølge opfindelsen yderligere den fordel, at motoren også kan anvendes ved defekt triac.Furthermore, the delay switch of the invention further provides the advantage that the motor can also be used in defective triac.
Den ville så blot udkoble samtidig med lampen, da strømmen kun løber 20 til motoren via triac'en i forsinkelsestiden.It would then simply switch off at the same time as the lamp, as the current only runs 20 to the motor via the triac during the delay time.
Med anbringelsen af styreelementet ifølge opfindelsen parallelt med den første mekaniske afbryder opnås de fordele, at forsinkelsesafbryderen kun behøver tre tilslutninger, nemlig forbindelseskabler til lampe og motor og fasetilslutningen, og også at der ved sluttet håndbe-25 tjent afbryder ikke er spænding på styreelementet. Derved forhindres uønskede fejl kobl inger af styreelementet.With the arrangement of the control element according to the invention parallel to the first mechanical switch, the advantages are obtained that the delay switch only needs three connections, namely lamp and motor connection cables and the phase connection, and also that with the closed hand operated switch there is no voltage on the control element. This prevents unwanted faults coupling of the control element.
Ifølge en yderligere udformning af forsinkelsesafbryderen er der foran styreelementets indgang koblet en diode i gennemgangsretningen i serie med en højohmsk modstand. Derved afpasses spændingsforløbet efter 30 styreelementets behov.According to a further embodiment of the delay switch, a diode in the passage direction is connected in series with a high ohmic resistance in front of the control element input. Thereby, the voltage flow is adjusted according to the needs of the control element.

På tegningen viser: fig. 1 kredsløbsdiagrammet for en forsinkelsesindretning ifølge 35 opfindelsen, - 4 -The invention is further explained by means of an exemplary embodiment which is shown roughly schematically in the drawing.

fig. 2 anskueliggør strømmen i den håndbetjente afbryders gren i forsinkelsesafbryderen og, i afhængighed heraf, strømforløbet i triac'ens gren.FIG. 2 illustrates the current in the branch of the hand-operated switch in the delay switch and, as a result, the current in the branch of the triac.
5 Forsinkelsesindretningen arbejder med en forsinkelsesafbryder ifølge fig. 1. Denne indkobler samtidig en lampe 1 og en motor 2 til en ventilator. Efter udkobling af lampen 1 kører motoren 2 stadigvæk videre i et fast tidsrum. Lampen 1 og motoren 2 er anbragt i adskilte grene af en strømkreds. En håndbetjent afbryder 3 har en første meka-10 ni sk afbryder 31 i grenen til lampen 1 og en anden mekanisk afbryder 32 i grenen til motoren 2. De to mekaniske afbrydere 31 og 32 er koblet indbyrdes gennem en stiv, ikke ledende forbindelse og brydes eller sluttes altid samtidigt med kun ét manuelt aktiveringselement.5 The delay device operates with a delay switch according to FIG. 1. It also switches on a lamp 1 and a motor 2 to a fan. After switching off the lamp 1, the motor 2 continues to run for a fixed period of time. The lamp 1 and the motor 2 are arranged in separate branches by a circuit. A hand operated switch 3 has a first mechanical switch 31 in the branch of the lamp 1 and a second mechanical switch 32 in the branch of the motor 2. The two mechanical switches 31 and 32 are interconnected through a rigid, non-conductive connection and are broken. or always ends simultaneously with only one manual activation element.
Den anden mekaniske afbryder 32 er anbragt i grenen til motoren 2 15 således, at den danner en shuntforbindelse med en triac 4, til hvis gate 41 er koblet en styreudgang 53 fra et styreelement 5.The second mechanical switch 32 is positioned in the branch of the motor 2 15 to form a shunt connection with a triac 4 to which gate 41 is coupled a control output 53 from a control element 5.
Styreelementet 5 er koblet parallelt med den første mekaniske afbryder 31, som findes i grenen til lampen 1. Ved et spændingsfald på belastningssiden af tilslutningen 51 i styreelementet 5, således som 20 det frembringes ved brydning af den håndbetjente afbryder 3, kommer der spænding på styreudgangen 53 på styreelementet 5. Derved gøres triac'en 4 ledende. Følgelig løber der også efter brydning af den håndbetjente afbryder 3 en strøm via triac'en 4 og forsyner motoren 2.The control element 5 is coupled in parallel to the first mechanical switch 31, which is located in the branch of the lamp 1. In the case of a voltage drop on the load side of the connection 51 in the control element 5, as produced by breaking the hand-operated switch 3, voltage is applied to the control output. 53 on the control element 5. This makes the triac 4 conductive. Accordingly, even after breaking the hand-operated switch 3, a current flows through the triac 4 and supplies the motor 2.
Styreelementet 5 indeholder et tidselement, fx et RC-led, som fra 25 tidspunktet for et spændingsfald på belastningssiden af tilslutningen 51 efter et fast, forudbestemt tidsrum igen sætter spændingen på styreudgangen 53 på nul. Som følge heraf spærrer triac'en 4, og ved fortsat brudt håndbetjent afbryder 3 udkobler motoren 2.The control element 5 contains a timing element, for example an RC link, which, from the time of a voltage drop on the load side of the connection 51, after a fixed predetermined period of time, resets the voltage of the control output 53 to zero. As a result, the triac blocks 4, and in case of continued broken hand-operated switch 3, the motor 2 shuts down.
Til beskyttelse af styreelementet 5 er der i tilledningen til be-30 lastningssiden af tilslutningen 51 på styreelementet 5 seriekoblet en diode 6 og en højohmsk modstand 7.To protect the control element 5, a diode 6 and a high ohmic resistor 7 are connected in series in the supply to the load side of the connection 51 on the control element 5 in series.
For at tydeliggøre forsinkelsesafbryderens funktionsmåde ifølge opfindelsen viser fig. 2 skematiseret for varigheden af en frakoblingsperiode forløbet af spændingen U51 på belastningssiden af tilslutningen 35 51 samt forløbet af spændingen U53 på styreudgangen 53 i styreelementetIn order to clarify the operation of the delay switch according to the invention, FIG. 2 schematically illustrated for the duration of a switch-off period, the voltage U51 on the load side of the connection 35 51 and the voltage U53 on the control output 53 in the control element

- 5 - 5.- 5 - 5.
Når den håndbetjente afbryder 3 sluttes til tidspunktet ti, er der netspænding både på lampen 1 og på motoren 2. Samtidigt ligger der en spænding U51 på tilslutningen 51 til styreelementet 5. På den anden 5 tilslutning 52 i styreelementet 5 er der imidlertid den samme spænding, således at styreudgangen 53 forbliver spændingsfri, og triac'en 4 ikke tændes. Triac'en 4 belastes endnu ikke, og en eventuel defekt i triac'en påvirker endnu ikke funktionen i lampen 1 og motoren 2.When the hand-operated switch 3 is connected to time ten, there is mains voltage both on the lamp 1 and on the motor 2. At the same time there is a voltage U51 on the connection 51 to the control element 5. On the other 5 connection 52 in the control element 5, however, the same voltage is so that the control output 53 remains voltage free and the triac 4 does not turn on. The triac 4 is not yet loaded, and any defect in the triac does not yet affect the function of lamp 1 and motor 2.
Når den håndbetjente afbryder 3 atter åbnes til tidspunktet t2, 10 udkobler lampen 1 i strømkredsens første gren straks, og spændingen U51 på belastningssiden af tilslutningen 51 i styreelementet 5 falder til nul. Dette spændingsfald på tilslutningen 51 udløser styreelementet, hvis styreudgang 53 skifter til spænding. Følgelig bliver* triac'en 4 ledende, og den mekaniske afbryder 32 i grenen til motoren 2 shuntes.When the hand-operated switch 3 is again opened to time t2, 10 the lamp 1 in the first branch of the circuit immediately switches off and the voltage U51 on the load side of the connection 51 in the control element 5 drops to zero. This voltage drop on the connection 51 triggers the control element, whose control output 53 changes to voltage. Accordingly, the * triac 4 becomes conductive and the mechanical switch 32 in the branch of the motor 2 is shunted.
15 Ved frakoblet lampe 1 kører motoren 2 altså videre.15 If the lamp 1 is switched off, the motor 2 thus continues.
Efter et fast tidsrum, som bestemmes fra tidspunktet t2 for spændingsfaldet på tilslutningen 51 ved hjælp af et RC-led i styreelementet 5, kobler styreelementet 5 til tidspunktet t3 igen styreudgangen 53 til spændingsfri. Følgelig spærrer triac'en 4, og motoren 2 frakobles for-20 sinket ved fortsat afbrudt håndbetjent afbryder 3.After a fixed period of time determined from the time t2 of the voltage drop on the connection 51 by means of an RC link in the control element 5, the control element 5 switches the control output 53 to the voltage-free again at the time t3. Consequently, the triac 4 locks and the motor 2 is switched off by the sustained disconnected hand operated switch 3.
