- an obliquely backwards sloping sealing flange 11 is formed.
- On the sealing flange 11 is a complementary sealing flange 12 of the upper container part 6.
- the contact between the flanges 11, 12 does not have to be hermetically sealed, but a possible gap between them should be so narrow that the air circulation through such a gap is small compared to that formed by a slot formed in the upper container part 6 (here several slots) ) Passage 13 when it is released from a closure element arranged thereon, here a grid 14 which is displaceable in the depth direction.
- the upper container part 6 is connected to a ceiling 15 of the storage compartment 3 with vertical play, z. B. by means of engaging in slots hook 16, suspended to allow close contact of the sealing flanges 11, 12, even if the container parts 5, 6 are not exactly over and placed among themselves.

- the control of the fan 17 and the actuator 18 by the control unit can be done in different ways.
- the fan 17 is continuously in operation to keep a slow, with less than 2 m / s, circulating air flow in the container 4 in motion, which prevents or reduces the formation of a temperature and humidity gradient within the container 4 and so ensures that the detected by the humidity sensor 19 locally at its installation humidity value for the entire volume of the container 4 is representative.

- the humidity threshold may also be set to values other than the 85% rH mentioned above.
- the limit should definitely be higher than the equilibrium humidity of the product to be cooled 23, but should also be far enough below 100% rH to exclude dew formation in relatively cool, possibly shielded by refrigerated goods 23 of the air flow of the fan 17 areas of the container 4 to be able to.

- the operation of the fan 17 is closely oriented to the needs. Need for operation of the fan 17 is when there is a significant gradient of the temperature or humidity in the container 4. On the existence of a temperature gradient can, for. B. are closed when the measured value of the temperature sensor 20 differs significantly from that of a temperature sensor, not shown in the figure, which is mounted in a conventional manner to a wall of the storage compartment 3 and serves to control the compressor operation.
- a gradient of the temperature or the humidity can also be measured directly on the container 4 if it has at least two sensors of the same type at different locations. Since, on the one hand cold air tends to collect at the bottom of the container 4 and on the other hand, the container 4 predominantly on its front is exposed to heat inflow while being cooled from behind, a temperature or humidity gradient is most likely to form between a relatively cold or wet area in the bottom and rear walls of the container 4 and a relatively warm or dry area in a front upper corner Consequently, a second sensor should be spaced vertically and / or in the depth direction from the sensors 19, 20 and preferably at the lower container part 5, in particular at its rear wall 9.
- the sensors 26, 27 may also be accommodated in a housing 41 fixed in the storage compartment 3, for example projecting from the rear wall 29, which engages in the opening 24 of the rear wall 9 when the container part 5 is inserted into the storage compartment 3.
- This on its engaging in the container 4 tip pierced housing 41 may, as in Fig. 4 shown to be tapered forward so that it is easily and safely inserted into the opening 24 and a stop position to which the container 4 in the storage compartment 3 is inserted and in which the opening 24 is substantially sealed, by contact of the Housing 41 is defined with the edges of the opening 24.
- the housing 41 may be provided with a circumferential flexible skirt 42, for example made of rubber, which adjoins the rear wall 9 snugly in the inserted position and the opening 24 also closes tightly when the housing 41 itself does not touch the edges of the opening 24.
- an evaporator 28 is arranged on the rear side of the storage compartment 3.
- the evaporator 28 is here shown spaced from the rear wall 29 of the body 1, but it could also be a known coldwall evaporator, which is inserted between an inner container and an insulating layer of the rear wall 19.
- the fan 22 is arranged to drive air circulation along the free surface of the evaporator 28 and around the walls 7, 9, 10, ceiling 39 and bottom 40 of the container 4, thus minimizing the temperature gradient in the storage compartment 3 and in the container 4, respectively to care.
- a no-frost structure comes into consideration, such.
- Fig. 6 shown where the evaporator and its associated fan outside the range shown, for. B. in a conventional manner in an evaporator chamber under the ceiling of the body 1, are housed, and the fan drives a cold air flow along a guided over the rear wall 29 channel 30, which exits through openings 31 of the rear wall 29 into the storage compartment 3:
- the cold air flows to the container 4, heats up and rises on the inside of the door 2 again in the direction of the evaporator chamber.
- the rear wall 9 may have a double-walled structure.
- a heat transfer material 35 such as a brine or a water-alcohol mixture
- the evaporator of a no-frost refrigerator is generally provided with a defrost heater to thaw frost deposited on the evaporator during operation and to drain the condensate. If a defrost has taken place, the compressor has to run again for some time before the evaporator chamber has cooled down to the extent that all remaining behind dew water residues are frozen again. If the fan of the evaporator chamber is running in such a time, the moisture content of the air exiting at the openings 31, the limit for the air in the container 4, which leads to the opening of the passage 13 exceed. Under these conditions, leaving the passage 13 open would not lead to a reduction, but to an increase in the humidity in the container 4. Therefore, the monitoring of the humidity in the container 4 is preferably exposed in such a situation, and the passage 13 remains closed regardless of the humidity value in the container 4 until the evaporator chamber is cooled down again.

Description
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, das speziell geeignet ist zur Lagerung von gegen Austrocknung empfindlichem Kühlgut. Die Haltbarkeit von nicht steril und luftdicht verpackten Lebensmitteln in einem Kältegerät ist durch mikrobiellen Verderb, chemische und enzymatische Verderbsprozesse sowie durch Austrocknen begrenzt. Frische Lebensmittel wie Obst, Gemüse, Salate oder frische Kräuter geben - neben der durch die natürliche Respiration freigesetzten Feuchte - solange Feuchtigkeit an ihre Umgebung ab, bis sich ein Gleichgewicht zwischen ihnen und der umgebenden Luft eingestellt hat. Die damit einhergehende Austrocknung dieser Lebensmittel ist meist irreversibel und führt dazu, dass diese Lebensmittel als nicht mehr verzehrtauglich beurteilt werden, lange bevor der Verzehr tatsächlich aufgrund einer eventuellen Besiedlung durch Mikroorganismen gesundheitlich bedenklich wäre. Um frische Lebensmittel in einem Kältegerät lange unter Bewahrung ihrer Qualität lagern zu können, ist es daher wünschenswert, die Verdunstung zu minimieren. Andererseits muss eine Lagerung bei zu hoher Luftfeuchtigkeit vermieden werden, da diese wiederum das Wachstum von Mikroorganismen stark fördern würde.The present invention relates to a refrigeration appliance, in particular a household refrigeration appliance, which is particularly suitable for the storage of desiccated refrigerated goods. The shelf life of non-sterile and airtight packaged foods in a refrigerator is limited by microbial spoilage, chemical and enzymatic spoilage processes, and drying out. Fresh foods such as fruits, vegetables, salads or fresh herbs - in addition to the moisture released by the natural respiration - release moisture into their environment until equilibrium is established between them and the surrounding air. The resulting dehydration of these foods is usually irreversible and causes these foods are judged to be no longer verzehrtauglich long before the consumption would be due to a possible colonization by microorganisms of health concern. To be able to store fresh food in a refrigerator for a long time while maintaining its quality, it is therefore desirable to minimize evaporation. On the other hand, a storage at too high humidity must be avoided, as this in turn would greatly promote the growth of microorganisms.
Aus
Aufgabe der Erfindung ist, ein Kältegerät zu schaffen, das verbesserte Lagerbedingungen für frisches, Feuchtigkeit abgebendes Kühlgut bieten kann.The object of the invention is to provide a refrigeration device that can provide improved storage conditions for fresh, moisture-emitting refrigerated goods.
Die Aufgabe wird gelöst durch ein Kältegerät mit den Merkmalen des Anspruchs 1. Der Ventilator ermöglicht es, lokale Temperatur- und Feuchtigkeitsunterschiede in dem Behälter zu minimieren, ohne dass die von ihm umgewälzte Luft über den Durchgang den Behälter verlassen kann. Die Luftfeuchtigkeit kann daher auf einem hohen Wert konstant gehalten werden, ohne dass die Gefahr von Tauwasserbildung im Behälter besteht. Die Steuereinheit ist eingerichtet, das Verschlusselement anhand der im Lagerraum herrschenden Luftfeuchtigkeit zu steuern, um die Abgabe feuchter Luft aus dem Lagerraum zu ermöglichen, wenn dies zur Verhinderung von Kondenswasserbildung im Lagerraum erforderlich ist. Da der Behälter nicht oder allenfalls zu einem geringem Teil durch den Zufluss von Kaltluft von außen gekühlt, sondern durch Kontakt seiner Wand mit einem mit einem Lagerfach, in dem der Behälter angeordnet ist, ist eine Kühlung des Behälters bei geringer Temperaturdifferenz zwischen Behälter und Lagerfach möglich. Je geringer diese Temperaturdifferenz ist, umso geringer ist auch die Neigung zur Ausbildung von Temperaturgradienten in dem Behälter, die durch Betrieb des Ventilators wieder beseitigt werden müssten.The object is achieved by a refrigeration device with the features of
Damit die vom Ventilator angetriebene Luftzirkulation nicht ihrerseits wiederum die Austrocknung des Kühlguts fördert, sollte der Ventilator so angeordnet und dimensioniert sein, dass die Geschwindigkeit des Luftstroms im Lagerraum nirgends 2 m/sec überschreitet.So that the fan-driven air circulation does not in turn promote the desiccation of the refrigerated goods, the fan should be arranged and dimensioned be that the speed of the air flow in the storage room nowhere exceeds 2 m / sec.
Zweckmäßigerweise sollte die Steuereinheit eingerichtet sein, den Durchgang zu öffnen, wenn die Luftfeuchtigkeit an wenigstens einem Messpunkt im Lagerraum einen Grenzwert übersteigt.Conveniently, the control unit should be set up to open the passage if the humidity exceeds a limit at at least one measuring point in the storage room.
Vorzugsweise nimmt die Steuereinheit den Ventilator in Betrieb, wenn die Differenz der Luftfeuchtigkeit und/oder der Temperatur zwischen zwei Messpunkten in dem Lagerraum einen Grenzwert übersteigt.The control unit preferably starts the fan when the difference between the humidity and / or the temperature between two measuring points in the storage space exceeds a limit value.
Um Kühlgut in dem Behälter bequem handhaben zu können, ist es zweckmäßig, wenn der Behälter wenigstens ein unteres und ein oberes Behälterteil umfasst und das untere Behälterteil ohne das obere Behälterteil bewegbar, insbesondere aus dem Lagerfach entnehmbar, ist.In order to handle refrigerated goods in the container convenient, it is advantageous if the container comprises at least a lower and an upper container part and the lower container part without the upper container part movable, in particular from the storage compartment removed.
Komponenten, die zu ihrem Betrieb an Energieversorgungs- oder Signalleitungen angeschlossen sein müssen, wie etwa das Verschlusselement, der Ventilator oder ein Sensor sind vorzugsweise an dem oberen Behälterteil vorgesehen.Components that need to be connected to power or signal lines for their operation, such as the shutter member, the fan or a sensor, are preferably provided on the upper tank part.
Das Lagerfach kann seinerseits einen zweiten Ventilator aufweisen, um in dem Lagerfach einen Luftstrom anzutreiben, der den Behälter umspült und so für eine gleichmäßige Temperaturverteilung auf der Behälterwand sorgt.The storage compartment may in turn comprise a second fan to drive in the storage compartment a flow of air which flows around the container and thus ensures a uniform distribution of temperature on the container wall.
Wenn das Kältegerät ein No-Frost-Gerät ist, kann als zweiter Ventilator zweckmäßigerweise der Ventilator dienen, der bei einem Gerät dieses Typs herkömmlicherweise den Luftaustausch zwischen dem Lagerfach und einer Verdampferkammer antreibt.When the refrigeration device is a no-frost device, the second ventilator may suitably be the ventilator which, in a device of this type, conventionally drives the exchange of air between the storage compartment and an evaporator chamber.
Wenn ein Verdampfer, der das Lagerfach kühlt, mit einer Abtauheizung versehen ist, kann die Steuereinheit eingerichtet sein, den Durchgang geschlossen zu halten, während die Abtauheizung im Betrieb ist, und so den Zutritt von relativ warmer, feuchter Luft ins Inneren des Behälters während des Abtauens zu verhindern.When an evaporator that cools the storage compartment is provided with a defrost heater, the control unit may be configured to keep the passage closed while the defrost heater is in operation, and thus to allow relatively warm, humid air to enter the interior of the container during operation To prevent defrosting.
Um Temperaturschwankungen und mit ihnen einhergehende Schwankungen der relativen Luftfeuchtigkeit in dem Lagerraum zu minimieren, kann die Wand des Lagerraums auf wenigstens einem Teil ihrer Fläche mit einem Wärmespeichemedium versehen sein. Um eine große Wärmemenge in einer kleinen Menge des Wärmespeichermediums speichern zu können, ist das Wärmespeichermedium zweckmäßigerweise so gewählt, dass eine Phasenübergangstemperatur des Wärmespeichermediums mit der Betriebstemperatur des Kältereservoirs übereinstimmt. Vorzugsweise ist das Wärmespeichermedium an einem Teil der Wand angeordnet, das einen vom zweiten Ventilator angetriebenen Kaltluftstrom ausgesetzt ist.In order to minimize temperature fluctuations and associated variations in the relative humidity in the storage room, the wall of the storage room may be provided on at least part of its surface with a heat storage medium. In order to store a large amount of heat in a small amount of the heat storage medium, the heat storage medium is suitably chosen so that a phase transition temperature of the heat storage medium coincides with the operating temperature of the cold reservoir. Preferably, the heat storage medium is disposed on a portion of the wall exposed to a cold air flow driven by the second fan.
Eine weitere Maßnahme, mit der Temperaturgradienten und -schwankungen in dem Lagerraum minimiert werden können, ist, dass die Wand wenigstens auf einem Teil ihrer Fläche eine Außenwand, eine Innenwand und einen isolierenden Spalt dazwischen umfasst.Another measure, with which temperature gradients and fluctuations in the storage space can be minimized, is that the wall comprises at least part of its surface an outer wall, an inner wall and an insulating gap therebetween.

Ein in dem Lagerfach 3 untergebrachter, z. B. aus Kunststoff spritzgeformter Behälter 4 umfasst ein unteres Behälterteil 5 und ein oberes Behälterteil 6. Das untere Behälterteil 5 ist auf dem Boden des Lagerfachs 3 in Tiefenrichtung verschiebbar aufgestellt. Es umfasst eine der Tür 2 zugewandte Vorderwand 7, an der ein Griff 8 zur Erleichterung der Handhabung angeformt ist, eine Rückwand 9, die weniger hoch als die Vorderwand 7 ist, und Seitenwände 10, deren obere Kanten von der Vorder- 7 zur Rückwand 9 hin kontinuierlich abfallen. Entlang der Oberkanten der Wände 7, 9, 10 ist ein schräg nach hinten abfallender Dichtflansch 11 gebildet. Auf dem Dichtflansch 11 liegt ein komplementärer Dichtflansch 12 des oberen Behälterteils 6 auf. Der Kontakt zwischen den Flanschen 11, 12 muss nicht hermetisch dicht sein, ein eventueller Spalt zwischen ihnen sollte jedoch so eng sein, dass die Luftzirkulation durch einen solchen Spalt klein ist gegenüber der durch einen in dem oberen Behälterteil 6 gebildeten (hier aus mehreren Schlitzen bestehenden) Durchgang 13, wenn dieser von einem daran angeordneten Verschlusselement, hier einem in Tiefenrichtung verschiebbaren Gitter 14, freigegeben ist.One in the
Das obere Behälterteil 6 ist an einer Decke 15 des Lagerfachs 3 mit vertikalem Spiel, z. B. mit Hilfe von in Langlöchern eingreifenden Haken 16, aufgehängt, um einen engen Kontakt der Dichtflansche 11, 12 auch dann zu ermöglichen, wenn die Behälterteile 5, 6 nicht exakt über- und untereinander platziert sind.The
Am oberen Behälterteil 6 sind ein Ventilator 17, ein an dem Gitter 14 angreifendes Stellglied 18, ein Luftfeuchtesensor 19 sowie eventuell auch ein Temperatursensor 20 montiert. Der Ventilator 17, das Stellglied 18 und die Sensoren 19, 20 sind über ein Leitungsbündel 21 an eine hier nicht dargestellte elektronische Steuereinheit des Kältegerät angeschlossen, der außer der Steuerung des Ventilators 17 und des Stellglieds 18 anhand von Messdaten der Sensoren 19, 20 auch die Steuerung eines am Lagerfach 3 außerhalb des Behälters 4 angeordneten zweiten Ventilators 22 und, in fachüblicher Weise, eines hier nicht dargestellten Verdichters des Kältegeräts obliegt.At the
Die Steuerung des Ventilators 17 und des Stellglieds 18 durch die Steuereinheit kann auf unterschiedliche Weise erfolgen. Im einfachsten Falle ist der Ventilator 17 kontinuierlich in Betrieb, um eine langsam, mit weniger als 2 m/s, zirkulierende Luftströmung im Behälter 4 in Gang zu halten, die die Ausbildung eines Temperatur- und Luftfeuchtegradienten innerhalb des Behälters 4 verhindert oder verringert und so dafür sorgt, dass der von dem Luftfeuchtesensor 19 lokal an dessen Einbauort erfasste Luftfeuchtigkeitswert für das gesamte Volumen des Behälters 4 repräsentativ ist. Überschreitet dieser Wert eine obere Grenze von z.B. 85 % + ε rH, wobei ε ein kleiner positiver Wert, z.B. 0,5 %, ist, dann steuert die Steuereinheit das Stellglied 18 an, um den Durchgang 13 zu öffnen. Indem so feuchte Luft aus dem Behälter 4 in das umgebenden Lagerfach 3 geblasen wird und trockenere Luft von dort in den Behälter 4 zurückströmt, wird in diesem die Luftfeuchtigkeit weit genug abgesenkt, um den Niederschlag von Tauwasser innerhalb des Behälters 4 zu verhindern. Wenn der Messwert des Sensors 19 auf 85% - ε abgenommen hat, wird das Stellglied 18 erneut angesteuert, um den Durchgang 13 zu schließen. Die Luftfeuchtigkeit im Behälter 4 variiert folglich in einem sehr engen Intervall von 2 ε, und die Menge an Feuchtigkeit, die von im Behälter 4 gelagertem Kühlgut 23 abgeben wird, um einen Gleichgewichtswert der Luftfeuchtigkeit aufrechtzuerhalten, ist sehr gering.The control of the
Bei offenem Durchgang 13 kann die Leistung des Ventilators 17 heraufgesetzt werden, um einen schnellen Luftaustausch zwischen Behälter 4 und Lagerfach 3 zu erreichen und den Durchgang 13 schnell wieder schließen zu können.When the
Der Einschaltgrenzwert der Luftfeuchtigkeit kann natürlich auch auf andere Werte als die oben genannten 85 % rH festgelegt sein. Der Grenzwert sollte auf jeden Fall höher sein als die Gleichgewichts-Luftfeuchtigkeit des Kühlguts 23, sollte aber auch weit genug unter 100 % rH liegen, um Tauwasserbildung in relativ kühlen, eventuell durch Kühlgut 23 von der Luftströmung des Ventilators 17 abgeschirmten Bereichen des Behälters 4 ausschließen zu können. Um die Wahrscheinlichkeit, dass solche abgeschirmten Bereiche entstehen, zu minimieren, kann, wie in
Einer Weiterentwicklung zufolge ist auch der Betrieb des Ventilators 17 eng am Bedarf orientiert. Bedarf nach Betrieb des Ventilators 17 besteht dann, wenn ein deutlicher Gradient der Temperatur oder der Luftfeuchtigkeit im Behälter 4 vorliegt. Auf die Existenz eines Temperaturgradienten kann z. B. geschlossen werden, wenn der Messwert des Temperatursensors 20 deutlich von dem eines in der Figur nicht dargestellten Temperatursensors abweicht, der in an sich bekannter Weise an einer Wand des Lagerfachs 3 angebracht ist und zur Steuerung des Verdichterbetriebs dient.According to a further development, the operation of the
Ein Gradient der Temperatur oder der Luftfeuchtigkeit kann natürlich auch unmittelbar am Behälter 4 gemessen werden, wenn dieser wenigstens zwei Sensoren des gleichen Typs an verschiedenen Stellen aufweist. Da einerseits kalte Luft dazu neigt, sich am Boden des Behälters 4 zu sammeln und andererseits der Behälter 4 überwiegend an seiner Vorderseite einem Wärmezufluss ausgesetzt ist, während er von hinten gekühlt wird, bildet sich ein Temperatur- oder Feuchtigkeitsgradient am ehesten zwischen einem relativ kalten bzw. feuchten Bereich in Boden- und Rückwandnähe des Behälters 4 und einem relativ warmen bzw. trockenen Bereich in einer vorderen oberen Ecke des Behälters 4. Ein zweiter Sensor sollte folglich vertikal und/oder in Tiefenrichtung von den Sensoren 19, 20 beabstandet und vorzugsweise am unteren Behälterteil 5, insbesondere an dessen Rückwand 9, angeordnet sein.Of course, a gradient of the temperature or the humidity can also be measured directly on the
Wenn ein solcher zweiter Sensor am unteren Behälterteil 5 fest montiert ist und dieses zur Handhabung des Kühlguts 23 aus dem Kältegerät entnehmbar sein soll, ergibt sich das Problem, die Signale eines solchen Sensors an die Steuereinheit zu übertragen. Bei der in
Alternativ zur Darstellung der
Einer weiteren, in
Das Vorhandensein von in Richtung des Temperatur- oder Feuchtegradienten beabstandeten Sensoren 19, 20, 26, 27 für Temperatur und Luftfeuchtigkeit erlaubt z. B. eine Steuerung des Ventilators 17, bei der der Ventilator 17 immer dann eingeschaltet wird, wenn die Differenz zwischen den von den Luftfeuchtesensoren 19, 27 gemessenen Luftfeuchtigkeitswerten einen Grenzwert von z. B. 4% rH überschreitet oder die Differenz zwischen den Messwerten der Temperatursensoren 20, 26 einen Grenzwert von 0,3 K überschreitet und der Ventilator wieder ausgeschaltet wird, sobald beide Grenzwerte unterschritten sind.The presence of spaced in the direction of the temperature or

Selbstverständlich kommt auch ein No-Frost-Aufbau in Betracht, wie z. B. in
Der Verdampfer eines No-Frost-Kältegeräts ist im Allgemeinen mit einer Abtauheizung versehen, um an dem Verdampfer im Laufe des Betriebs niedergeschlagenen Reif aufzutauen und das Tauwasser abfließen zu lassen. Wenn ein Abtauvorgang stattgefunden hat, muss der Verdichter erst einige Zeit wieder laufen, bevor die Verdampferkammer soweit abgekühlt ist, dass alle dort zurückgebliebenen Tauwasserreste wieder gefroren sind. Wenn in einer solchen Zeit der Ventilator der Verdampferkammer läuft, kann der Feuchtigkeitsgehalt der an den Öffnungen 31 austretenden Luft den Grenzwert für die Luft im Behälter 4, der zum Öffnen des Durchgangs 13 führt, überschreiten. Unter diesen Bedingungen würde ein Offenstehen des Durchgangs 13 nicht zu einer Verringerung, sondern zu einer Steigerung der Luftfeuchtigkeit im Behälter 4 führen. Daher ist vorzugsweise in einer solchen Situation die Überwachung der Luftfeuchtigkeit im Behälter 4 ausgesetzt, und der Durchgang 13 bleibt unabhängig vom Luftfeuchtigkeitswert im Behälter 4 so lange geschlossen, bis die Verdampferkammer wieder ausgekühlt ist.The evaporator of a no-frost refrigerator is generally provided with a defrost heater to thaw frost deposited on the evaporator during operation and to drain the condensate. If a defrost has taken place, the compressor has to run again for some time before the evaporator chamber has cooled down to the extent that all remaining behind dew water residues are frozen again. If the fan of the evaporator chamber is running in such a time, the moisture content of the air exiting at the
