Description

Die Erfindung betrifft ein Verfahren zum Betreiben gekühlter Verkaufsmöbel mit einem einen Temperaturfühler aufweisenden Thermostaten zur Erfassung der Raumtemperatur innerhalb des gekühlten Verkaufsmöbels.The invention relates to a method for operating cooled sales furniture with a thermostat having a temperature sensor for detecting the room temperature within the cooled sales furniture.

Zur Zeit ist es üblich, Kühlmöbel, insbesondere offene gekühlte Verkaufsmöbel, ob mit oder ohne Nachtabdeckung, mit einem konstant eingestellten Thermostaten zu betreiben. Außerhalb der Verkaufszeiten, d. h. nachts und an Sonn- und Feiertagen sowie während der Betriebsferien und vor allem mit geschlossener Abdeckung, bleibt die Kältemaschine solange in Betrieb, bis außer der Luft auch die Warentemperatur konstant ist. Bei geschlossener Abdeckung, z. B. herabgelassenem Rollo; kann keine Wärme mehr an die Umgebung abgeführt werden und die Temperatur innerhalb des Verkaufsmöbels fällt soweit ab, daß die Ware, beispielsweise Milch, möglicherweise anfriert.At the moment it is common to operate refrigerated cabinets, in particular open refrigerated sales cabinets, with or without night cover, with a constant thermostat. Outside of sales hours, i.e. H. at night and on Sundays and public holidays as well as during the company holidays and especially with the cover closed, the refrigerator remains in operation until the temperature of the goods is constant in addition to the air. With the cover closed, e.g. B. lowered blind; heat can no longer be dissipated to the surroundings and the temperature inside the sales furniture drops to such an extent that the goods, for example milk, may freeze.

Die US-A-3,727,419 beschreibt einen Kühlschrank mit einem in diesem angeordneten Kontrollthermostaten. Der Thermostat weist einen Temperaturfühler zur Erfassung der Raumtemperatur innerhalb des Kühlschrankes auf. Der Temperaturfühler wird während den Zeiten, in denen die Tür des Kühlschrankes öfters geöffnet wird, beheizt. Mit diesem Verfahren und der dazugehörigen Vorrichtung sollen lange Stillstandszeiten der Kältemaschinen vermieden werden.US-A-3,727,419 describes a refrigerator with a control thermostat arranged therein. The thermostat has a temperature sensor to record the room temperature inside the refrigerator. The temperature sensor is heated during the times when the refrigerator door is opened frequently. This method and the associated device are intended to avoid long downtimes of the chillers.

Die US-A-3,465,536 behandelt eine Abdeckeinrichtung für Kühlmöbel, die insbesondere in Nachtstunden angebracht wird. Die Nachtabdeckung ist dabei mit einer Abtaukontrolleinheit verbunden, so daß bei Inbetriebnahme der Nachtabdeckung keine Abtauung erfolgt.US-A-3,465,536 deals with a covering device for refrigeration cabinets, which is attached in particular at night. The night cover is connected to a defrost control unit so that no defrost takes place when the night cover is started up.

Der Erfindung liegt die Aufgabe zugrunde, eine kostengünstige und einfache Temperaturregelung zur Verfügung zu s.tellen, mit der außerdem Energie eingespart werden kann und eine zu niedrige Temperatur im Inneren des Verkaufsmöbels außerhalb der Verkaufszeiten verhindert wird.The invention has for its object to provide an inexpensive and simple temperature control with which energy can also be saved and a too low temperature inside the sales furniture is prevented outside of the sales times.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß während den Verkaufszeiten der Temperaturfühler zur Simulierung einer höheren Temperatur elektrisch beheizt und der Thermostat so justiert wird; daß bei beheiztem Temperaturfühler die gewünschte Temperatur im Warenraum aufrechterhalten wird und daß außerhalb der Verkaufszeiten der Temperaturfühler nicht beheizt wird.This object is achieved in that during the sales times the temperature sensor to simulate a higher temperature is electrically heated and the thermostat is adjusted; that the desired temperature is maintained in the goods area when the temperature sensor is heated and that the temperature sensor is not heated outside of the sales times.

Durch die erfindungsgemäße Maßnahme wird die Temperatur innerhalb der Warenzone im Tagesbetrieb auf dem gleichen Wert gehalten wie bisher, während im Nachtbetrieb die Temperatur gegenüber der bisherigen Verfahrensweise leicht angehoben wird. Dazu wird während der Verkaufszeiten am Temperaturfühler durch elektrische Beheizung eine höhere Temperatur simuliert und gleichzeitig der Thermostat so justiert, daß in dem Warenraum die gewünschte Kühltemperatur herrscht. Nach Verkaufsschluß wird die Beheizung der Temperaturfühler ausgeschaltet, so daß dieser die wirkliche Temperatur mißt. Infolgedessen arbeitet der Thermostat bei etwas höherer Temperatur, so daß die Kühitemperatur in dem Warenraum ebenfalls um einige Grad ansteigt.As a result of the measure according to the invention, the temperature within the goods zone is kept at the same value in daytime operation as before, while in nighttime operation the temperature is raised slightly compared to the previous method. For this purpose, a higher temperature is simulated by electrical heating during the sales times on the temperature sensor and at the same time the thermostat is adjusted so that the desired cooling temperature prevails in the goods room. At the end of the sale, the heating of the temperature sensors is switched off so that it measures the real temperature. As a result, the thermostat operates at a slightly higher temperature, so that the cooling temperature in the store also rises by a few degrees.

Durch das erfindungsgemäße Verfahren wird Energie eingespart, da weniger Kälteleistung erforderlich ist, und außerdem verhindert, daß die Ware anfriert.The method according to the invention saves energy because less cooling power is required and also prevents the goods from freezing.

Gemäß einer vorteilhaften Ausgestaltungsform des Erfindungsgedankens wird die Beheizung des Temperaturfühlers gemeinsam mit der Möbel-und/oder Ladenbeleuchtung ein- und ausgeschaltet. Nach einer weiteren bevorzugten Ausführungsform kann die Beheizung des Temperaturfühlers auch bei Betätigung eines als Nachtabdeckung dienenden Rollos ausgeschaltet werden.According to an advantageous embodiment of the inventive concept, the heating of the temperature sensor is switched on and off together with the furniture and / or shop lighting. According to a further preferred embodiment, the heating of the temperature sensor can also be switched off when a roller blind serving as a night cover is actuated.

Eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens weist unter anderem einen mit einem Temperaturfühler ausgestatteten Thermostaten auf. Erfindungsgemäß ist der Thermostat mit einem als Heizwiderstand ausgebildeten Heizelement versehen, der Heizwiderstand über einen Transformator und ein Relais mit einer Schwachstromqueile verbunden, der Transformator und das Relais außerhalb der Kühlzone angebracht und mit einer zusammen mit der Beheizung des Temperaturfühlers ein-oder ausschaltenden elektrischen Einrichtung verbunden.A device for carrying out the method according to the invention has, inter alia, a thermostat equipped with a temperature sensor. According to the invention, the thermostat is provided with a heating element designed as a heating resistor, the heating resistor is connected to a low-current source via a transformer and a relay, the transformer and the relay are arranged outside the cooling zone and connected to an electrical device which switches on or off together with the heating of the temperature sensor .

Das erfindungsgemäße Verfahren und die zugehörige Vorrichtung lassen sich auf alle Kühl-und Tiefkühlmöbel anwenden.The method according to the invention and the associated device can be applied to all refrigeration and freezer furniture.

Im folgenden wird ein Ausführungsbeispiel anhand einer Figur schematisch dargestellt.An exemplary embodiment is shown schematically below with reference to a figure.

Die Figur zeigt im Querschnitt ein offenes gekühltes Verkaufsmöbel, das im Beispiel als Kühlregal 1 beschrieben ist.The figure shows in cross section an open refrigerated display case, which is described in the example as a cooling shelf 1.

Das Kühlregal 1 weist einen Kühlmöbelkorpus 2 aus einem wärmeisolierenden Material auf, der in seinem unteren Ende als Wanne ausgebildet ist. Eine Abdeckung 3 trennt einen Warenraum 4, der mehrere Konsolen 5 zur Lagerung von zu kühlender Ware aufweist, von dem Innenraum 6 der Wanne, in dem ein Verdampfer 7 eines Thermostaten und als Einrichtung zur Luftförderung ein Ventilator 8 angeordnet sind. Der Ventilator 8 dient zur Luftumwälzung, wobei die Luft zunächst am Verdampfer 7, der Teil eines Kältekreislaufes ist, vorbeiströmt, dann über einen Luftschacht an der Rückwand der Kühltruhe nach oben und zwischen die Konsolen gelangt und an der Vorderseiten der Konsolen als Kaltluftvorhang nach unten strömt. Die Luftströmung ist durch Pfeile 9 angedeutet. Zur Nachtabdeckung weist das Kühlregal 1 ein Rollo 10 auf.The cooling shelf 1 has a refrigerator body 2 made of a heat-insulating material, which is designed in its lower end as a tub. A cover 3 separates a goods room 4, which has a plurality of brackets 5 for storing goods to be cooled, from the interior 6 of the tub, in which an evaporator 7 of a thermostat and as a device for air delivery, a fan 8 are arranged. The fan 8 is used for air circulation, the air first flowing past the evaporator 7, which is part of a refrigeration cycle, then via an air duct on the rear wall of the freezer upwards and between the brackets and flows down on the front of the brackets as a cold air curtain . The air flow is indicated by arrows 9. To cover the night, the cooling shelf 1 has a roller blind 10.

Ein Temperaturfühler 11 des Thermostaten ist innerhalb der Kühlzone des Warenraums 4, beispielsweise an der gezeigten Stelle, angebracht. Erfindungsgemäß ist dieser Temperaturfühler 11 mit einem als Heizwiderstand ausgebildeten Heizelement versehen. Da das Heizelement im Feuchtbereich des Kühlregals liegt, wird der Heizwiderstand meist vergossen eingebaut. Als zusätzliche Sicherung und zur Energieeinsparung wird der Heizwiderstand mit Schwachstrom (z. B. 12V) gespeist. Ein dafür erforderlicher Transformator und ein Relais, die zusammen in einem Gehäuse 12 eingebaut sind, sind an einem geeigneten Platz außerhalb der Kühlzone bzw. des Feuchtbereiches montiert und mit beispielsweise dem Schalter für die Möbel- und/oder Ladenbeleuchtung verbunden. Die Betätigung der Beheizung des Temperaturfühlers 11 kann auch über eine Schaltuhr erfolgen.A temperature sensor 11 of the thermostat is mounted inside the cooling zone of the goods room 4, for example at the point shown. According to the invention, this temperature sensor 11 is provided with a heating element designed as a heating resistor. Since the heating element is in the wet area of the cooling shelf, the heating resistor is usually installed in a potted form. As an additional safeguard and to save energy, the heating resistor is fed with low current (e.g. 12V). A required transformer and a relay, which are installed together in a housing 12, are mounted in a suitable place outside the cooling zone or the wet area and connected to, for example, the switch for the furniture and / or shop lighting. The heating of the temperature sensor 11 can also be operated via a time switch.

Während der Verkaufszeiten wird der Temperaturfühler 11 mit z. B. 0,2 W beheizt. Auf diese Weise wird am Temperaturfühler 11 eine um beispielsweise 2 bis 4°C höhere Temperatur simuliert. Gleichzeitig wird der Thermostat bzw. Verdampfer 7 so justiert, daß die Kühlluft mit einer Temperatur von z. B. - 3'°C in den Luftschacht an der Rückwand eintritt, wodurch innerhalb des Warenraumes 4 die gewünschte Temperatur, die den gleichen Wert wie bisher hat, beispielsweise + 5 °C, eingestellt wird.During the sales times, the temperature sensor 11 with z. B. 0.2 W heated. In this way, a temperature which is higher by, for example, 2 to 4 ° C. is simulated on the temperature sensor 11. At the same time the thermostat or evaporator 7 is adjusted so that the cooling air with a temperature of z. B. - 3 '° C in the air duct on the rear wall, whereby the desired temperature within the goods room 4, which has the same value as before, for example + 5 ° C, is set.

Nach Verkaufsschluß wird die Beheizung des Temperaturfühlers 11 beispielsweise gemeinsam mit der Möbel-. und/oder Ladenbeleuchtung oder bei Betätigung der Nachtabdeckung abgeschaltet, und der Temperaturfühler 11 mißt die wirkliche Temperatur. Infolgedessen arbeitet der Thermostat bzw. Verdampfer 7 bei um einige Grad höherer Temperatur, so daß die Kühlluft in den Luftschacht erwärmt, z. B. mit 0 °C, eintritt. In dem Warenraum 4 herrscht trotz der leicht erwärmten Kühlluft die gleiche Temperatur wie während der Verkaufszeiten, da bei geschlossenem Rollo keine Wärme an die Umgebung abgegeben wird und somit weniger kalte Luft ausreicht, um die gleiche Kühltemperatur zu erzeugen.After the sale closes, the heating of the temperature sensor 11, for example, together with the furniture. and / or shop lighting or when the night cover is actuated, and the temperature sensor 11 measures the actual temperature. As a result, the thermostat or evaporator 7 operates at a few degrees higher temperature, so that the cooling air in the duct heats up, for. B. with 0 ° C occurs. Despite the slightly warmed cooling air, the same temperature prevails in the goods room 4 as during the sales times, since when the roller blind is closed, no heat is emitted to the surroundings and therefore less cold air is sufficient to generate the same cooling temperature.

Durch die erfindungsgemäße Maßnahme wird verhindert, daß die Ware, beispielsweise Milch, durch Temperatursenkung in Folge der Nachtabdeckung anfriert. Da bei Nachtabdeckung geringere Kälteleistung nötig ist, um die gleiche Kühltemperatur zu erzeugen, werden durch das erfindungsgemäße Verfahren außerdem erhebliche Energieeinsparungen erzielt.The measure according to the invention prevents the goods, for example milk, from freezing due to the temperature drop as a result of the night cover. Since less cooling capacity is required in the case of night coverage in order to generate the same cooling temperature, the method according to the invention also achieves considerable energy savings.
