Description

Die Erfindung betrifft eine Warenkühltheke insbesondere zur Kühlung von empfindlichen Lebensmitteln wie Frischfisch mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a refrigerated goods counter especially for cooling sensitive Food such as fresh fish with the characteristics of the generic term of Claim 1.

Bei herkömmlichen Kühltheken wird meistenteils die Umluftströmung auch dann aufrecht erhalten, wenn das Kühlaggregat abgeschaltet ist. Bei empfindlichen Lebensmitteln wie Frischfisch trocknet der stetige Luftstrom die Ware aus und lässt sie unansehnlich werden. Die Vermeidung oder wenigstens die weitgehende Reduzierung einer solchen Warenaustrocknung ist Aufgabe der Erfindung. Diese Aufgabe wird durch Anspruch 1 gelöst.With conventional refrigerated counters, the circulating air flow is usually also used maintained when the cooling unit is switched off. For sensitive foods like fresh fish, the constant air flow dries out the goods and leaves they become unsightly. Avoiding or at least largely reducing it Such drying of the goods is the object of the invention. This Object is solved by claim 1.

Durch die Maximierung des Volumens des Wannenraumes unterhalb des Warenbodens kann sich dort bei Stillstand des Umluftventilators und bei dadurch unterbundener Umluftströmung ein Maximum an überfeuchteter Luft ansammeln. Die Luftüberfeuchtung ist eine Folge bereits der systembedingt vorliegenden Abkühlung der den Wannenraum bildenden bzw. umgebenden Wand- bzw. Bodenflächen. In Abhängigkeit von der thermostatgesteuerten Wiedereinschaltung des Kühlaggregates und der damit verbundenen Funktionsaufnahme des Verdampfers wird die Umluftströmung durch Einschaltung des Ventilators wieder in Gang gesetzt. Dadurch wird die im Wannenraum angesammelte, überfeuchtete Luft bereits dann über die Warenauslage hinübergeblasen, wenn der Verdampfer noch nicht voll aktiviert ist und seine volle Kühlfunktion aufgenommen hat. Die Strömung der überfeuchteten Luft über die im Warenraum ausgelegte Ware befeuchtet sie, ohne dass sie bereits ihren vollen Kühleffekt auf die Ware ausübt. Damit wird eine zwischenzeitlich eingetretene Warenaustrocknung wieder ausgeglichen, bevor die Umluftströmung kühlt. Durch die Maximierung des Volumens des Wannenraumes unterhalb des Warenbodens wird die Menge an dort zur Verfügung stehender, überfeuchteter Luft maximiert, ohne dass es dazu einer Volumenvergrößerung der gesamten Kühltheke bedarf. Diese Volumenmaximierung wird dadurch erreicht, dass der Wannenraum unterhalb des Warenbodens von Funktionsteilen, insbesondere vom Verdampfer freigehalten ist.By maximizing the volume of the tub space below the product floor can occur there when the air recirculation fan is at a standstill and Accumulate circulating air flow a maximum of over-humidified air. The Air humidification is a consequence of the system-related cooling the wall or floor surfaces forming or surrounding the tub space. Depending on the thermostat-controlled restart of the Cooling unit and the associated function of the evaporator the circulating air flow starts again by switching on the fan set. As a result, the over-humidified air that has accumulated in the tub is already there then blown over the goods display when the evaporator is still is not fully activated and has started its full cooling function. The current the humidified air humidified over the goods displayed in the goods room them without already having their full cooling effect on the goods. This compensates for any drying out of goods that has occurred in the meantime, before the circulating air flow cools. By maximizing the volume of the tub space below the product floor, the amount of there becomes Available, over-humidified air is maximized without being one Volume increase of the entire refrigerated counter is required. This volume maximization is achieved in that the tub space below the goods floor from functional parts, especially from the evaporator.

Besonders einfach und zweckmäßig ist eine Synchronein- und -abschaltung von Kühlaggregat und Umluftventilator (Anspruch 2). Die Kühlwirkung und deren Konstanz wird durch eine zusätzliche Eisbefüllung des Warenbodens begünstigt (Anspruch 3). Die Tropflöcher gemäß Anspruch 4 begünstigen die erwünschte Luftüberfeuchtung im Wannenraum unterhalb des Warenbodens. Der Maximierung des Aufnahmevolumens des Wannenraumes unterhalb des Warenbodens dient die Positionierung des Kühlaggregates innerhalb des Luftschachtes zum Warenraum außerhalb des Wannenraumes (Anspruch 5).Synchronous switching on and off is particularly simple and expedient Cooling unit and recirculation fan (claim 2). The cooling effect and its constancy is favored by an additional ice filling of the goods floor (claim 3). The drip holes according to claim 4 favor the desired air humidification in the tub below the product floor. Maximizing of the receiving volume of the tub space below the goods floor the positioning of the cooling unit within the air shaft to the goods room outside the tub space (claim 5).

Durch die erfindungsgemäße Reduzierung bzw. Minimierung der Austrocknung der Warenauslage wird z.B. bei Fischen ein unansehnlicher Grauschleier vermieden, der die Kunden von einem Kauf abhält. Die Stillstandsphasen sowohl des Kühlaggregats als auch des Umluftventilators bedeuten im Übrigen eine Energieersparnis.By reducing or minimizing drying out according to the invention the goods display is e.g. avoid an unsightly gray haze on fish, that keeps customers from making a purchase. The downtimes of both The cooling unit and the recirculation fan also save energy.

Die Erfindung wird unter Zuhilfenahme der beigefügten Zeichnung näher erläutert.The invention is explained in more detail with the aid of the attached drawing.

Die Warenkühltheke enthält einen Thekenkorpus 1, eine Thekenwanne 2, eine Thekenabdeckung 3, eine Bedienplatte 4, einen Verdampfer 5, wenigstens einen Ventilator 6 und einen in der Thekenwanne 2 angeordneten Warenboden 7. Auf dem Warenboden 7 befindet sich ein Vorrat aus zerkleinertem Eis 8, auf bzw. in dem die zu präsentierende Ware 9, etwa Fische und Fischprodukte, gelagert sind. Der Warenboden 7 teilt in etwa horizontaler Richtung den gesamten Thekenraum in einen unteren positionierten Wannenraum 10 und in einen oberhalb des Warenbodens 7 positionierten Warenraum 11. An der Bedienseite 12 der Theke ist ein vertikal verlaufender Luftschacht 13 angeordnet, in dessen unterem Teil der mit einem (nicht dargestellten) Kühlaggregat verbundene Verdampfer 5 positioniert ist. Oberhalb des Verdampfers 5 ist innerhalb des Luftschachtes 13 wenigstens ein Ventilator 6 angeordnet, der im Betrieb eine durch die Richtungspfeile 14 angedeutete Luftströmung erzeugt.The goods refrigerated counter contains a counter body 1, a counter tub 2, one Counter cover 3, an operating panel 4, an evaporator 5, at least one Fan 6 and a shelf 7 arranged in the counter tub 2 the goods base 7 is a stock of crushed ice 8, on or in to which the goods to be presented 9, such as fish and fish products, are stored. The merchandise shelf 7 divides the entire counter space in an approximately horizontal direction in a lower positioned tub space 10 and in one above the goods floor 7 positioned goods room 11. On the service side 12 is the counter a vertically extending duct 13 arranged in the lower part of the with an evaporator 5 (not shown) connected to the cooling unit is. Above the evaporator 5 is at least within the air shaft 13 a fan 6 is arranged, which in operation by the directional arrows 14 indicated airflow generated.

Zur Steuerung der Kühlung des über die durch die Thekenabdeckung hindurch sichtbaren Ware 9 streichenden Luftstromes 14 ist innerhalb des Luftschachtes 13 oder an einer anderen geeigneten Stelle außerhalb des Wannenraumes 10 ein Temperatursensor 15 angeordnet. Wenn die Luft im Bereich des Temperatursensors 15 eine unterhalb eines Schwellenwerts liegende Temperatur aufweist, wird bzw. ist der Verdampfer 5 bzw. das Kühlaggregat abgeschaltet. Steigt die Lufttemperatur über diesen oder einen anderen vorwählbaren Schwellenwert, so schaltet sich das Kühlaggregat zu. Gleichzeitig wird der Ventilator 6 eingeschaltet, so dass bei laufendem Kühlaggregat eine Umluftströmung in Richtung der Pfeile 14 vorhanden ist. Während der Betriebsphase des Kühlaggregats nimmt die Luftströmung 14 naturgemäß Feuchtigkeit sowohl vom Eis als auch von der darin gelagerten Ware 9 auf und gibt diese am Verdampfer 5 durch Kondensation wieder ab. Erreicht Sobald jedoch die Lufttemperatur im Bereich des Temperatursensors 15 einen unteren Schwellenwert, werden der Verdampfer 5 und der Ventilator 6 abgeschaltet. Die Luftströmung 14 kommt nun zum Stillstand. Es liegen dann Kühlverhältnisse wie bei Theken mit einer ausschließlichen Eiskühlung vor. Das Eis 8 und auch die darauf präsentierte Ware 9 geben Feuchtigkeit ab, die sich wegen der fehlenden Luftströmung oberhalb des Warenbodens 7 ansammelt und quasi ein Mikroklima mit hoher Luftfeuchtigkeit bildet. In dieser kalten Luftschicht mit praktisch feuchtigkeitsgesättigter Luft ist naturgemäß die Austrocknung der Waren 9 äusserst gering.To control the cooling of the through the counter cover visible goods 9 air stream 14 is within the duct 13 or at another suitable location outside the tub space 10 a temperature sensor 15 is arranged. If the air in the area of the temperature sensor 15 has a temperature below a threshold value, the evaporator 5 or the cooling unit is or is switched off. The increases Air temperature above this or another preselectable threshold, see above the cooling unit switches on. At the same time the fan 6 is switched on so that with the cooling unit running, a circulating air flow in the direction of the arrows 14 is present. During the operating phase of the cooling unit, the Air flow 14 naturally moisture both from the ice and from it stored goods 9 and returns them to evaporator 5 by condensation from. Once reached, however, the air temperature in the area of the temperature sensor 15 a lower threshold, the evaporator 5 and the fan 6 switched off. The air flow 14 now comes to a standstill. Then there are Cooling conditions as with counters with exclusive ice cooling. The Ice 8 and also the goods 9 presented on it give off moisture that is because of the lack of air flow above the floor 7 and creates a microclimate with high humidity. In this cold layer of air with practically moisture-saturated air the drying out of the Were 9 extremely low.

Während einer Stillstandsphase schmilzt das Eis zu einem gewissen Teil ab. Damit das Schmelzwasser wenigstens in gewissem Umfang abfließen kann, sind im Warenboden 7 Schlitze oder Bohrungen vorhanden, die sein Abfließen in den Wannenraum 10 erlauben. Das Schmelzwasser wird am Wannenboden 16 gesammelt und bei Bedarf abgezogen. Der unterhalb des Warenbodens 7 befindliche Wannenraum 10 ist indessen mit gekühlter und feuchtigkeitsgesättigter Luft angefüllt. Wenn nun der Verdampfer 5 bzw. das Kühlaggregat und der Ventilator 6 zugeschaltet werden, wird der sich unterhalb des Warenbodens 7 befindende Luft- und Feuchtigkeitsvorrat im Wannenraum 10 in Richtung der Umluftströmung 14 mobilisiert. Während der Anfangsphase des Betriebes des Verdampfers 5 steht in der in Umlaufrichtung 14 mobilisierten, noch nicht wirksam heruntergekühlten Luftströmung noch ein erhöhter Feuchtigkeitsvorrat zur Verfügung. Dementsprechend ist der Austrocknungseffekt der anfänglich umgewälzten Luft besonders gering. Erst nach längerer Betriebsdauer des Kühlaggregates sinkt der Feuchtigkeitsgehalt der umgewälzten Luft auf Werte ab, die dem Feuchtigkeitsgehalt herkömmlicher Umlufttheken entsprechen.To a certain extent, the ice melts during a standstill phase. In order to the melt water can drain off at least to a certain extent are in Goods floor 7 slots or holes are present, which drain into the Allow tub space 10. The melt water is collected on the tub floor 16 and subtracted if necessary. The one located below the shelf 7 Trough space 10 is, however, with cooled and moisture-saturated air filled. If the evaporator 5 or the cooling unit and the fan 6 are switched on, the one located below the goods floor 7 Air and moisture supply in the tub space 10 in the direction of the circulating air flow 14 mobilized. During the initial phase of the operation of the evaporator 5 is in the mobilized in the direction of rotation 14, not yet effectively cooled down Air flow still an increased moisture reserve available. Accordingly, the drying effect of the initially circulated air is particularly low. It only drops after the cooling unit has been in operation for a long time Moisture content of the recirculated air to values that correspond to the moisture content correspond to conventional convection counters.

Untersuchungen mit Fischvorräten haben gezeigt, dass der Flüssigkeitsverlust der Fische etwa 37 g pro Stunde und Quadratmeter beträgt. Bei einer Warentheke mit synchroner Zu- und Abschaltung von Kühlaggregat und Ventilator beträgt der Flüssigkeitsverlust 11 g pro Stunde und Quadratmeter. Bei Eistheken ohne Zusatzkühlung, die hinsichtlich des Flüssigkeitsverlustes der Waren optimal sind, beträgt dieser Wert 7,6 g pro Stunde und Quadratmeter. Bei der erfindungsgemäßen Theke liegen somit hinsichtlich der Warenaustrocknung Verhältnisse vor, die mit einer Eistheke ohne Zusatzkühlung vergleichbar sind. Dabei ist jedoch eine zuverlässigere Kühlung möglich. Die Waren können so gekühlt werden, dass ihre vorgeschriebene Kerntemperatur sicher eingehalten wird. Studies with fish stocks have shown that the fluid loss of the Fish is about 37 g per hour and square meter. At a counter with The synchronous switching on and off of the cooling unit and fan is the Loss of fluid 11 g per hour and square meter. For ice cream counters without additional cooling, which are optimal with regard to the loss of liquid in the goods, this value is 7.6 g per hour and square meter. In the case of the invention The counter is therefore in terms of drying out conditions that are comparable to an ice cream counter without additional cooling. However, there is one more reliable cooling possible. The goods can be cooled so that their prescribed core temperature is safely observed.
