Abstract

Thermostat for regulating operative temperature comprising temperature sensing element for the air space (1) that controls a radiant heater (3). The purpose of this invention is to produce a thermostat that can regulate heating devices based on the operative temperature of the locale. This is achieved by a compensation heater core (5) being placed near and situated to affect the temperature sensing element (1) and a thermistor (6) being exposed to radiant heat from the surroundings in order to control heat development in the compensation heater core (5) so that it increases when the radiant heat from the surroundings increases.<IMAGE>

Description

8405263-8 så att den känner av -strâlvärmen från infravàrmarna. .Om givaren placeras i "skuggan" från infravärmarna kommer den att reglera utifrån lufttemperaturen. Detta medfor att den opertiva temperaturen minskar med stigande utetemperatur vilket gor att det känns svalare i lokalen ju varmare det är utet Om man däremot har en tillförlitlig givare för operativ temperatur kopplas I infravärmarna in då den upplevda temperaturen i lokalen blir for låg._Temperaturen i lokalen känns därvid behaglig hela tiden. 8405263-8 so that it senses the radiant heat from the infrared heaters. .If the sensor is placed in the "shadow" from the infrared heaters it will regulate based on the air temperature. This means that it the operative temperature decreases with increasing outdoor temperature which makes it feel cooler in the room the warmer it is If, on the other hand, you have a reliable sensor for operation temperature is switched on in the infrared heaters when it is experienced the temperature in the room becomes too low._The temperature in the room feels comfortable all the time.

För reglering av kompensationselementet används normalt en termonegativ termistor. Samtliga, för regleringen viktiga, element, bimetallen. accelerations- samt kompensationselementet är placerade inuti ett termostathus och ar därvid ,anordnade att avkanna enbart lufttemperaturen.Swedish patent no. 345,059 describes, for example, a thermostat for regulating radiators and whose 4temperature- sensing element 'is a bimetallic; To achieve a smooth temperature control and prevent regulation ~ the point is used acceleration elements and compensation elements which are arranged to influence the bimetal. For regulation of the compensation element is normally used a thermonegative thermistor. All elements important for regulation, bimetals. the acceleration and compensation element is placed inside a thermostat housing and are thereby, arranged to detect only the air temperature.

UPPFINNINGENS ÄNDAMÅL OCH VIKTIGASTE KÄNNETECKEN Ändamålet med föreliggande uppfinning är att åstadkomma en termostat som kan reglera uppvärmningsanordningar utifrân den operativa temperaturen i lokalen. Detta åstadkommes därigenom att ett kompensationselement är placerat nära, och anordnat att påverka, det temperaturkannande elementet , att en termistur som ar anordnad att exponeras För strålningsvärme från omgivningen. är anordnad att styra värmeutvecklingen i kompensationselementet . så att den ökar nar strålningsvärmen från omgivningen ökar.OBJECTS AND MOST IMPORTANT CHARACTERISTICS OF THE INVENTION The object of the present invention is to provide one thermostat that can regulate heating devices from it operating temperature in the room. This is accomplished thereby that a compensation element is placed close to, and arranged to influence, the temperature sensing element, that a thermisture that is arranged to be exposed to radiant heat from the surroundings. is arranged to control the heat development in the compensation element. so that it increases when the radiant heat from the environment increases.

KORT BESKRIVNING AV RITNINGÅRNA Uppfinningen kommer i det följande -att beskrivas i ett utfdringsexempel under hänvisning till bifogade ritningar§ 8405263-8 Figur 1 visar ett diagram over den energibesparing som erhålls om en lokal uppvärms med både strålningsvarme och luftvärme, figur 2 visar en uppfinningsenlig termostat for operativ temperatur, och 7 figur 3 visar en känd elektronisk termostat kompletterad med en uppfinningsenlig kompensator För stråltemperaturen.BRIEF DESCRIPTION OF THE DRAWING YEARS The invention will hereinafter be described in one Exemplary embodiments with reference to the accompanying drawings§ 8405263-8 Figure 1 shows a diagram of the energy savings obtained if a room is heated with both radiant heat and air heat, figure 2 shows a thermostat according to the invention for operating temperature, and 7 figure 3 shows a known electronic thermostat supplemented with a compensator according to the invention For the beam temperature.

BESKRIVNING AV UTFÖRINGSEXEMPEL I figur 2 visas en enkel uppkoppling av en termostat enligt uppfinningen. Ett temperaturkännande element, ett bimetall- element 1, påverkar mekaniskt en strömställare 2 som sluter en strömkrets till en elektrisk belastning såsom en uppvärmnings- anordning 3 då- temperaturen sjunker under ett Förinställt bör-värde (ej närmare visat). Uppvärmningsanordningen 3 kan utgöras av exempelvis en infravärmare fór inomhusbruk.DESCRIPTION OF EMBODIMENTS Figure 2 shows a simple connection of a thermostat according to the invention. A temperature sensing element, a bimetallic element 1, mechanically acts on a switch 2 which closes one circuit to an electrical load such as a heating device 3 when the temperature drops below a Preset setpoint (not shown). The heating device 3 can consists of, for example, an infrared heater for indoor use.

Det temperaturkännande elementet 1 är anordnat i ett termostathus 4 vilket även rymmer strömställaren 2 och ett kompensationselement S. Kompensationselementet 5 är ständigt inkopplat i serie med en termistor 6 och värmer det temperaturkannande elementet 1 så att detta bryter strömmen till uppvarmningsanordningen 3 tidigare än vad som annars skulle vara fallet. Termistorn 6 är termonegativ, dvs ju högre temperatur den utsätts for desto lägre blir dess resistans och desto mer ström flyter genom termistorn 6 och kompensations~ motståndet 5. Ju högre strom som genomflyter kompensations- elementet 5 desto högre temperatur avger det till sin omgivning.The temperature sensing element 1 is arranged in one thermostat housing 4 which also holds the switch 2 and one compensation element S. The compensation element 5 is permanent connected in series with a thermistor 6 and heats it temperature sensing element 1 so that this interrupts the current to the heating device 3 earlier than otherwise would be the case. The thermistor 6 is thermonegative, ie the higher the temperature it is exposed to, the lower its resistance and the more current flows through the thermistor 6 and the compensation ~ resistor 5. The higher the current flowing through the compensation the element 5 the higher the temperature it emits to its environment.

Termistorn 6 är anordnad utanför termostathuset 4 på så sätt att den exponeras för omgivningens strålningsvarme. Detta kan t.ex. åstadkommas genom att termisturn 6 placeras 1 ett svartfärgat, tunnväggigt. halvklotsformat hus 7 eller liknande vilket placeras i strâlgângen från en eller Flera infravärmare (ej visade).The thermistor 6 is arranged outside the thermostat housing 4 in this way that it is exposed to the radiant heat of the surroundings. This can for example is achieved by placing the thermistor 6 in one black, thin-walled. hemispherical house 7 or similar which is placed in the beam from one or more infrared heaters (not shown).

I figur 3 visas en alternativ utföringsform enligt uppfinningen där en tidigare känd elektronisk termostat 8 som æoon QUALITY 8405263-8 styr en belastning 3 med hjälp av en tyristor TO kompletterats med kompensationseiement 5 och termistor G. Kompensations- elementet _5 har därvid anordnats vid termostatens 8 tempera» turkännanøe element 1 och påverkar detta genom 'sin värme- avgivning i beroende av omgivningens stråltemperatur.Figure 3 shows an alternative embodiment according to the invention where a previously known electronic thermostat 8 as æoon QUALITY 8405263-8 controls a load 3 by means of a thyristor TO supplemented with compensation element 5 and thermistor G. Compensation the element _5 has then been arranged at the temperature of the thermostat 8 » turkännanøe element 1 and affects this by 'its heat emission depending on the ambient radiation temperature.

Upnfinningen är naturligtvis inte begränsad' till det ovan beskrivna utföringsexemplet utan ett flertal alternativa utföringsformer år tänkbara inom ramen föi patentkravens skyddsomfång. Sålunda är det exempelvis tänkbart att använda en, termopositiv termistor som kopplas 1 serie med ett begrânsningsmofistånd och parallellt med kompansatinnselementet 5.The invention is of course not limited to the above described embodiment without a plurality of alternatives embodiments are conceivable within the scope of the claims scope of protection. Thus, for example, it is conceivable to use one, thermopositive thermistor connected 1 series with one boundary resistance and parallel to the compensating element 5.
