Description

Anordning ved motorvarmere. Device for engine heaters.

Foreliggende oppfinnelse vedrører motorvarmere som er forsynt mejd en fortrinnsvis dobbeltmantlet beholder, som på to adskilte høydenivåer er bestemt til å forbindes med motorens kjølevannsystem og som oppvarmes ved hjelp av en brenner. Motorvarmeren er nærmest bestemt til å anvendes for oppvarmning av bilmotorer før start i kjølig vær. Brenneren tilføres brensel, fortrinnsvis i gassform, gjennom en av en magnet påvirket ventil, idet magneten og en gnistinduktor samt tennplugg tilføres strøm fra bilens akkumulatorbat-teri for respektive ventilens åpning og brennerens tenning etter slutning av en trykkstrømbryter. Oppfinnelsen har til ho-vedoppgave å frembringe en forbedring av slike motorvarmere ved redusering av strømuttaket fra batteriet under motorvarmerens funksjon. Dette oppnås vesentlig derved at to strømkretser over batteriet og trykkstrømbryteren er tilsluttbare til en annen strømbryter som manøvreres av en av brenneren påvirket termostat, idet den ene strømkrets inneholder gnistinduktoren og tennpluggen og den annen magnet, og idet der i en mellom trykkstrøm-bryteren og magneten anbrakt shuntkrets sitter en motstand på en sådan måte at ved motorvarmerens start, de to strømkret-ser er tilsluttet batteriet, men etter at brenneren er tent, den termostatstyrte strømbryter bryter de to strømkretser og bare shuntkretsen får strøm fra batteriet for ventilens fastholdelse i den åpne stilling. Gnistinduktoren krever en forholdsvis stor strømstyrke, men behøver bare å være i gang en kortere tid. Likeledes krever ventilens magnet en forholdsvis stor strømstyrke ved selve åpningen, mens ven-tilen derimot kan fastholdes i den åpne stilling med en vesentlig mindre strømtil-førsel til magneten, hvilket muliggjøres ved shuntkretsen og den i denne innsatte motstand. The present invention relates to engine heaters which are provided with a preferably double-jacketed container, which is intended to be connected to the engine's cooling water system at two separate height levels and which is heated by means of a burner. The engine heater is almost certainly intended to be used for warming up car engines before starting in cold weather. The burner is supplied with fuel, preferably in gaseous form, through a valve affected by a magnet, as the magnet and a spark inductor as well as the spark plug are supplied with power from the car's accumulator battery for the valve's opening and the burner's ignition after closing a pressure switch. The main task of the invention is to produce an improvement of such engine heaters by reducing the current draw from the battery during the engine heater's function. This is essentially achieved by the fact that two current circuits above the battery and the pressure current switch are connectable to another current switch which is operated by a thermostat affected by the burner, one circuit containing the spark inductor and the spark plug and the other magnet, and while there in a between the pressure current switch and the magnet installed shunt circuit, a resistor is placed in such a way that when the engine heater starts, the two current circuits are connected to the battery, but after the burner is lit, the thermostatically controlled circuit breaker breaks the two current circuits and only the shunt circuit receives power from the battery for the valve's retention in the open score. The spark inductor requires a relatively large current, but only needs to be in operation for a shorter time. Likewise, the valve's magnet requires a relatively large amperage at the opening itself, while the valve, on the other hand, can be maintained in the open position with a significantly smaller current supply to the magnet, which is made possible by the shunt circuit and the resistor inserted in it.

Oppfinnelsen skal i det følgende be-skrives nærmere under henvisning til den på tegningene som eksempel viste utførel-sesform, idet også andre egenskaper som karakteriserer oppfinnelsen skal angis. Fig. 1—3 viser skjematisk en i henhold til oppfinnelsen utført anordning. Fig. 4—6 viser et koblingsskjema i forskjellige innstillingsstillinger av de sam-virkende elementer. Fig. 7 viser en anordning i henhold til en mojdifisert utførelse. I de forskjellige figurer er samme henvisningsbetegnelser anvendt for samme eller ekvivalente deler. In the following, the invention will be described in more detail with reference to the embodiment shown in the drawings as an example, as other characteristics that characterize the invention must also be indicated. Fig. 1-3 show schematically a device made according to the invention. Fig. 4-6 shows a connection diagram in different setting positions of the cooperating elements. Fig. 7 shows a device according to a modified embodiment. In the different figures, the same reference designations are used for the same or equivalent parts.

I fig. 1—6 betegner 10 motorens akku-mulatorbatteri og 12 det ved bilens fører-sete værende instrumentbord, på hvilket en hovedstrømbryter 14 er montert på vanlig måte. Til den for oppfinnelsen nødvendige utrustning hører en trykkstrømbryter 16 samt fortrinnsvis også en kontrollampe 18, som begge er anbrakt på instrumentbordet. In fig. 1-6, 10 denotes the engine's accumulator battery and 12 the instrument panel by the car's driver's seat, on which a main power switch 14 is mounted in the usual way. The equipment necessary for the invention includes a pressure current switch 16 and preferably also a control lamp 18, both of which are placed on the instrument panel.

Fra en gasolbeholder går en rørledning 20, i hvilken der fortrinnsvis er innsatt en gasstrykkontakt 22, til en av en elektromagnet 24 manøvrert ventil 25 og fra denne en ledning 26 til motorvarmerens brenner. VIotorvarmeren kan f. eks. være utført slik 3om det fremgår av patent nr. 97024 til hvilket der henvises for en nærmere be-skrivelse av sammes funksjon og virkemåte. Gasstrykkontakten 22 er ved hjelp av ledninger 28, 30 tilsluttet hovedstrømbryterens samt trykkstrømbryterens 16 ene pol. For at strøm skal kunne passere fra batteriet til strømbryteren 16, må derfor ledningen 20 stå under trykk. A pipeline 20, in which a gas pressure contact 22 is preferably inserted, runs from a gas oil container to a valve 25 operated by an electromagnet 24 and from this a line 26 to the engine heater's burner. The VIotor heater can e.g. be carried out as 3if it appears from patent no. 97024 to which reference is made for a more detailed description of the same's function and mode of operation. The gas pressure contact 22 is connected by means of wires 28, 30 to one pole of the main current switch and the pressure current switch 16. In order for current to pass from the battery to the circuit breaker 16, the line 20 must therefore be under pressure.

En termostatstyrt dobbeltpolet omkobler 32 har en pol 34, som over en ledning 35 står i direkte forbindelse med ledningen 30, og kontaktarmer eller en dobbeltarm 36, 38 som ved ledninger 39, 41 er tilsluttet strøm-bryteren 16. Strømbryteren 32 har videre to poler 40, 42, av hvilke den førstnevnte gjennom en ledning 43 i serie er forbundet med en gnistinjduktor 44, en tennplugg 46 og jord resp. batteriets negative pol. Polen 42 inngår i en krets 48 som fører til jord resp. batteriets 10 negative pol, og i hvilken magneten 24 er innkoblet. Strømbryteren 32 har ytterligere en pol 50 som er tilsluttet en ledning 52, i hvilken kontroll-lampen 18 er innsatt og som er tilsluttet jord resp. batteriets negative pol. En shuntkrets 54 forbinder ledningen 41 med magneten 24, idet der i denne krets er innsatt en forkoblingsmotstand 56. A thermostatically controlled double-pole switch 32 has a pole 34, which is in direct connection with the line 30 via a wire 35, and contact arms or a double arm 36, 38 which are connected to the circuit breaker 16 by wires 39, 41. The circuit breaker 32 also has two poles 40, 42, of which the former is connected through a wire 43 in series with a spark inductor 44, a spark plug 46 and ground resp. negative terminal of the battery. Pole 42 is part of a circuit 48 which leads to earth or the negative pole of the battery 10, and in which the magnet 24 is connected. The circuit breaker 32 has a further pole 50 which is connected to a wire 52, in which the control lamp 18 is inserted and which is connected to ground or negative terminal of the battery. A shunt circuit 54 connects the wire 41 to the magnet 24, as a ballast resistor 56 is inserted in this circuit.

Fig. 4 viser de forskjellige elementers innstilling når motorvarmeren ikke er i virksomhet. Hovedstrømbryteren 14 antas å være brutt. Likeledes er gasstrykkontakten 22 og trykkstrømbryteren 16 brutt, hvorfor systemet er strømløst. Kontaktarmene eller dobbeltarmen 36, 38 holdes med fjærkraft mot de to poler 40, 42. I henhol|d til fig. 5 er hovedstrømbryteren 14 sluttet og ledningen 20 står under trykk, hvorfor gasstrykkontakten 22 forbinder ledningene 28 og 30 med hverandre. Videre er trykkstrømbryteren 16 sluttet, og strøm går fra batteriets 10 positive pol gjennom ledningene 39, 41 til kontaktarmene 36, 38. Ved at disse ligger an mot polene 40, 42 får på den ene side magneten 24 strøm, således at den av samme regulerte ventil 25 åpner og gass strømmer til brenneren. På den annen side tilføres strøm til gnistinduktoren 44 og tennpluggen 46, hvorved den gass-luftblanjding som forlater brenneren antennes. Begge disse operasjoner er forholdsvis strømkrevende, men tar kort tid. I og med at brenneren er tent, vil dens hete forbrenningsgasser påvirke en termostat (som i det nevnte patent er be-tegnet med 50) som i sin tur omstiller armene 36, 38, slik at disse istedet kommer til anlegg mot strømbryterens 32 poler 34, 50 i henhold til fig. 6. Strømtilførselen til gnistinduktoren 44 og likeledes til magneten 24 avbrytes dermed via polen 42. Fig. 4 shows the setting of the various elements when the engine heater is not in operation. The main circuit breaker 14 is assumed to be broken. Likewise, the gas pressure contact 22 and the pressure current switch 16 are broken, which is why the system is without power. The contact arms or double arm 36, 38 are held by spring force against the two poles 40, 42. According to fig. 5, the main circuit breaker 14 is closed and the line 20 is under pressure, which is why the gas pressure contact 22 connects the lines 28 and 30 to each other. Furthermore, the pressure current switch 16 is closed, and current flows from the positive pole of the battery 10 through the wires 39, 41 to the contact arms 36, 38. As these are in contact with the poles 40, 42, on the one hand, the magnet 24 receives current, so that the same regulated valve 25 opens and gas flows to the burner. On the other hand, current is supplied to the spark inductor 44 and the spark plug 46, whereby the gas-air mixture leaving the burner is ignited. Both of these operations are relatively power-intensive, but take a short time. As the burner is lit, its hot combustion gases will affect a thermostat (which in the aforementioned patent is denoted by 50) which in turn adjusts the arms 36, 38, so that these instead come into contact with the poles 34 of the circuit breaker 32 , 50 according to fig. 6. The current supply to the spark inductor 44 and likewise to the magnet 24 is thus interrupted via the pole 42.

Som det fremgår av fig. 5 var også As can be seen from fig. 5 was also

shuntkretsen 54 strømførende under den første startperiode ved dens tilslutning til ledningen 41, idet imidlertid magneten 24 fikk hovedmengden av den nødvendige strøm direkte gjennom denne ledning. Etter kontaktarmenes 36, 38 omstilling i henhold til fig. 6, går fremdeles strøm gjennom shuntkretsen 54, men Idenne gang via ledningen 35, polen 34, armen 38 og ledningen 39. I den eneste nå gjenværende sluttede strømkrets inngår motstanden 56 og magneten 24, hvilket innebærer at strømforbruket blir vesentlig redusert, idet det dog er fullt tilstrekkelig til å. holde magnetventilen i sin åpne stilling. the shunt circuit 54 current-carrying during the first starting period at its connection to the line 41, the magnet 24 however receiving the main amount of the required current directly through this line. After the contact arms 36, 38 have been adjusted according to fig. 6, current still flows through the shunt circuit 54, but this time via the wire 35, the pole 34, the arm 38 and the wire 39. The only now remaining closed current circuit includes the resistor 56 and the magnet 24, which means that the power consumption is significantly reduced, although is fully sufficient to keep the solenoid valve in its open position.

Som det fremgår av fig. 6, er nå også kontrollampen 18 innkoblet i en i forhold til batteriet 10 sluttet strømkrets. I og med at lampen 18 tenner etter f. eks. 10—15 sekunder, kan strømbryteren 16 gå til brutt stilling. Ved den viste utførelsesform av-stenges motorvarmeren etter fullført opp-gave ved hjelp av hovedstrømbryteren 14, som bryter også [den siste strømkrets. Gasstrykkontakten som er av spesiell verdi når motorvarmeren manøvreres ved hjelp av tidsur, bryter strømmen hvis gassen i gasolbeholderen tar slutt, og hindrer all innkobling hvis beholderens utløpsventil ikke skulle ha åpnet seg. As can be seen from fig. 6, the control lamp 18 is now also connected in a closed circuit in relation to the battery 10. As the lamp 18 lights up after e.g. 10-15 seconds, the circuit breaker 16 can go to the broken position. In the embodiment shown, the engine heater is switched off after completion of the task by means of the main circuit breaker 14, which also breaks [the last circuit. The gas pressure contact, which is of particular value when the engine heater is operated by means of a timer, cuts the current if the gas in the LPG container runs out, and prevents all connection if the container's outlet valve should not have opened.

Utførelsesformen i henhold til fig. 7 adskiller seg fra den foregående hoved-sakelig derved at gnistinduktoren 44 og tennpluggen 46 er erstattet med en gløde-plugg resp. en glødetråd 60. Videre er omkobleren 32 erstattet me(d en omkobler 62 som er termostatstyrt, men bare har to poler 34 og 42. Elektromagneten 24 får likesom ved den foregående utførelsesform under det første startmoment, strøm via omkoblerens arm 38 ved at den ligger an mot polen 42. Glødepluggen 60 er ved ledninger 64, 66 parallellkoblet med elektromagneten 24 i forhold til startbatteriet 10, således at altså også glødepluggen 60 får strøm over polen 42 i omkobleren 62. I og med at armen 38 omstilles, slik at den istedet har kontakt med polen 34, vil ikke bare elektromagneten 24, men også gløde-pluggen 60 kobles i serie mejd forkoblings-motstanden 56. De får således begge strøm av redusert styrke. Med hensyn til gløde-pluggen 60 er denne strømtilførsel i og for seg uten nytte, men den er så ubetyde-lig at den ikke i nevneverdig grad belaster startbatteriet. Man får samtidig fordelen av en enklere omkobler uten at et skadelig strømforbruk behøver å tas med i bereg-ningen. The embodiment according to fig. 7 differs from the preceding mainly in that the spark inductor 44 and the spark plug 46 have been replaced with a glow plug or a filament 60. Furthermore, the switch 32 has been replaced with a switch 62 which is thermostatically controlled, but only has two poles 34 and 42. The electromagnet 24, as in the previous embodiment, during the first starting moment, receives current via the switch's arm 38 in that it lies towards the pole 42. The glow plug 60 is connected by wires 64, 66 in parallel with the electromagnet 24 in relation to the starter battery 10, so that the glow plug 60 also receives current via the pole 42 of the switch 62. As the arm 38 is adjusted, so that it instead has contact with pole 34, not only the electromagnet 24, but also the glow plug 60 will be connected in series with the ballast resistor 56. They thus both receive current of reduced strength. With respect to the glow plug 60, this power supply in and of itself without benefit, but it is so insignificant that it does not put a significant strain on the starter battery.

Lampen 18 er ved utførelsesformen i henhold til fig. 7 innkoblet under anord-ningens hele funksjonstid, hvilket likeledes The lamp 18 is in the embodiment according to fig. 7 switched on during the device's entire working life, which likewise

Device for engine heaters which omfatter en fortrinnsvis dobbeltmantlet beholder, som på to adskilte høydenivåer er bestemt til å forbindes med motorens kjøle vannsystem og som oppvarmes ved hjelp av en brenner, som tilføres brensel gjennom en av en elektromagnet påvirket ventil, idet elektromagneten og et tennorgan tilføres strøm fra et akkumulator-batteri for respektive ventilens åpning og brennerens tenning etter slutning av en trykkstrømbryter, karakterisert ved at to strømkretser over batteriet (10) og trykk-strømbryteren (16) er tilsluttbare til en omkobler (32, 62) som manøvreres av en av brenneren påvirket termostat, idet den ene strømkrets inneholder tennorganet (46, 60) og den annen elektromagneten (24), og idet der i en mellom trykkstrøm-bryteren (16) og magneten (24) anbrakt krets sitter en forkoblingsmotstand (56) på en sådan måte at ved motorvarmerens start, de to strømkretser er tilsluttet batteriet, men etter at brenneren er tent, den termostatstyrte omkobler innkobler forkob-lingsmotstanden i serie med elektromagneten for ventilens (25) fastholdelse i den åpne stilling med redusert strømforbruk. comprises a preferably double-jacketed container, which at two separate height levels is intended to be connected to the engine's cooling water system and which is heated by means of a burner, which is supplied with fuel through a valve affected by an electromagnet, the electromagnet and an ignition device being supplied with current from an accumulator -battery for the opening of the respective valve and the ignition of the burner after the end of a pressure switch, characterized in that two current circuits above the battery (10) and the pressure-current switch (16) are connectable to a switch (32, 62) which is operated by a thermostat affected by the burner, one circuit containing the ignition device (46, 60) and the second electromagnet (24), and since in a circuit placed between the pressure current switch (16) and the magnet (24) there is a ballast resistor (56) in such a way that when the engine heater starts, the two current circuits are connected to the battery, but after that the burner is lit, the thermostatically controlled switch engages the pre-connection resistor in series with the electromagnet for holding the valve (25) in the open position with reduced power consumption. 2. Anordning som angitt i påstand 1, karakterisert ved at de to strømkretser er parallellkoblet, hvorfor strøm går gjennom 'det som glødeplugg utførte tennorgan (60, fig. 7) også etter start-øyeblikket, dog med redusert strømstyrke i og med at forkob-lingsmotstanden (56) er innkoblet.2. Device as stated in claim 1, characterized in that the two current circuits are connected in parallel, which is why current flows through the ignition device (60, fig. 7) which was carried out as a glow plug even after the starting moment, however with a reduced amperage in that the -ling resistor (56) is switched on.
