Description

Die Erfindung betrifft ein Kühlgerät gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a cooling device according to the preamble of the first claim.

Bei einem bekannten Kühlgerät dieser Art (DE-GM 93 08 907) ist zum Ein- und Ausschalten des Netzversorgungsstromkreises ein manuell betätigbarer Netzschalter vorgesehen, der mittels elektromechanischer Kontakte den erforderlichen Schaltvorgang ausführt. Um dabei zu vermeiden, daß der Netzschalter unbeabsichtigt oder z.B. durch Kinder unzulässigerweise betätigt wird, ist dem Netzschalter eine durch eine Taste auslösbare Sperreinrichtung zugeordnet, die vom Netzschalter entfernt von dessen Betätigungselement angeordnet ist. Der Netzschalter ist dabei in Einschaltstellung verriegelt, wobei diese Verriegelung nur durch Betätigen der zusätzlichen Taste gezielt entriegelt werden kann und dann selbsttätig in die Ausschaltstellung schaltet. Bei dieser Ausführungsform ist der mechanische Aufwand für die so ausgebildete Kindersicherung beachtlich, wobei die getrennte Anordnung von Betätigungsknopf und Auslösetaste einen zusätzlichen Bauaufwand erfordert.In a known cooling device of this type (DE-GM 93 08 907) is for switching the Mains supply circuit a manually operable Mains switch provided by means of electromechanical Contacts performs the required switching operation. Around to avoid accidentally turning off the power switch or e.g. is improperly operated by children the power switch can be triggered by a button Locking device assigned that removed from the power switch is arranged by its actuator. Of the The mains switch is locked in the on position, this locking only by pressing the additional key can be specifically unlocked and then automatically switches to the off position. At this Embodiment is the mechanical effort for that trained child safety considerably, the separate arrangement of actuation button and release button requires additional construction work.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Kühlgerät gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch welche mit einfachen Mitteln ein unbeabsichtigtes Ausschalten des Netzschalters unterbunden werden kann. The invention is based, with one Cooling device according to the preamble of the first claim Take measures by which with simple means an unintentional turning off of the power switch can be prevented.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characteristic features of the first claim.

Bei einer Ausgestaltung eines Kühlgeräts gemäß der Erfindung wird der Netzschalter lediglich mit einer Einrichtung zur Ausschaltzeitverzögerung versehen, so daß bei einer unbeabsichtigten oder unzulässigen Betätigung des Netzschalters in der Einschaltstellung jedenfalls noch Zeit bleibt, den Einschaltzustand wieder herzustellen. Dabei ist es zweckmäßig, bei Ablauf des wählbaren oder vorbestimmten Zeitverzögerungswertes diesen Ablauf akkustisch und/oder optisch zu signalisieren, um auf den eingeleiteten Ausschaltvorgang aufmerksam zu machen. Dabei kann das entsprechende Signal auch über den Abschaltzeitpunkt hinaus zumindest optisch aufrechterhalten werden, um dem Verderb von ggf. noch eingelagerter Ware entgegenwirken zu können. Sicherheitshalber ist die entsprechende Einrichtung zur Ausschaltzeitverzögerung so aufgebaut, daß der Vorgang der Zeitverzögerung nur abläuft, solange ein Auslöseglied manuell betätigt wird. Ist die Zeitdauer dieser Betätigung kürzer als der voreingestellte Auslösezeitwert, schaltet die Einrichtung zweckmäßigerweise selbsttätig in den Ausgangszustand zurück, in welchem der voreingestellte Zeitverzögerungswert wieder aktiviert wird. Eine Abschaltung ist also nur dann möglich, wenn eine ausreichend lange Zeitspanne das Auslöseglied betätigt wird. Kurzzeitige Betätigungen des Auslösegliedes sind demnach unbeachtlich. Die dem Netzschalter zugeordnete Einrichtung zur Ausschaltzeitverzögerung weist vorzugsweise einen elektronisch steuerbaren Zeitschalter auf, der mittels eines elektrisch an seinen Steuereingang angeschlossenen Tastschalters zu starten ist. Nach dem Start muß dieser selbsttätig zurückstellende Tastschalter bis zum Ablauf der Verzögerungszeitspanne in betätigter Stellung gehalten werden, wenn eine tatsächliche Abschaltung eines entsprechenden Versorgungsstromkreis für das Kühlgerät erreicht werden soll. Andernfalls wird eine nur kurzzeitig dauernde Betätigung des Tastschalters ignoriert. Vorzugsweise weist die Einrichtung einen elektronischen Zähler auf, der auf einen vorbestimmten Verzögerungszeitwert voreingestellt ist und der während der Betätigung des der Zählersteuerung dienenden Tastschalters von einem voreingestellten Wert aus zurückzählt oder bis zu einem voreingestellten Wert hochzählt und dann den Ausschaltvorgang bewirkt. Ein dem Zählwert entsprechender Anzeigewert kann auf einer optischen Anzeigeeinrichtung, insbesondere einem LCD-Display angezeigt werden. Dabei ist es beispielsweise möglich, einen "Count-Down" von einem voreingestellten Wert, beispielsweise 5, während des Ablaufs der Zeitverzögerung auf einen anderen Wert, beispielsweise den Wert 0 zu zählen. Nach Abschluß dieses Zählvorganges wird das Gerät bzw. ein elektrisch betriebener Geräteteil ausgeschaltet. Zweckmäßig ist es dabei, zusätzlich oder alternativ neben der optischen Anzeige auch eine akkustische Anzeige zu steuern, die während des ablaufenden Zeitverzögerungswertes ein Signal abgibt, so daß nicht die optische Anzeige beobachtet werden muß und auch dritte Personen Kenntnis nehmen können. Die Steuerung des Ablaufs der Zeitverzögerungszeit wird vorzugsweise durch einen Mikroprozessor vorgenommen, der die entsprechenden Anzeigeelemente in Abhängigkeit von der Betätigung des Tastschalters steuert. Dabei ist es zweckmäßig, den Status des Gerätes bzw. des betreffenden abzuschaltenden Geräteteils in einem Speicher abzuspeichern, insbesondere in einem EEPROM, das zu Kundendienstzwecken abgefragt werden kann. Die Anzeige des Zeitverzögerungswertes kann hierbei auch im Wechsel mit einer Temperaturanzeige im gleichen Display und mittels der gleichen Anzeigeelemente vorgenommen werden. Die Einrichtung zur zeitverzögerten Abschaltung kann ein Element enthalten, das nach Art eines monostabilen Flip-Flop oder eines R-C-gesteuerten Schmitt-Trigger aufgebaut ist. Dabei ist es zweckmäßig, den Tastschalter gleichzeitig für die Wiedereinschaltung des Versorgungsstromkreises zu nutzen, wobei die Einschaltung ohne Zeitverzögerung erfolgt. Bei diesem Aufbau wird somit ein in einen elektrischen Versorgungsstromkreis eingeschalteter, insbesondere elektronisch ausgebildeter oder elektronisch gesteuerter Netzschalter nach einem manuell ausgelösten Start einer Zeitverzögerungseinrichtung zeitverzögert aus dem Einschaltzustand in den Ausschaltzustand geschaltet, wenn die Startbedingung der Zeitverzögerungseinrichtung über den voreingestellten Zeitverzögerungswert hinaus aufrechterhalten wird. Die Einschaltung des Netzschalters aus dem Ausschaltzustand erfolgt demgegenüber unverzögert. Soll jedoch auch das unbeabsichtigte Einschalten nur unter Zusatzbedingungen möglich sein, kann auch der Einschaltvorgang analog dem Ausschaltvorgang mit entsprechenden Einrichtungen gesteuert werden.In one embodiment of a cooling device according to the Invention is the power switch with only one Provide switch-off delay device so that in the event of inadvertent or inadmissible actuation of the In any case, the mains switch still has time in the switched-on position remains to restore the switch-on state. It is it expedient at the end of the selectable or predetermined Time delay value this process acoustically and / or optically to signal to the initiated To draw attention to the switch-off process. It can corresponding signal also beyond the switch-off time at least visually maintained to spoil it to counteract any goods that may still be stored. For the sake of safety, the appropriate facility for Switch-off time delay constructed so that the process of Time delay only expires as long as a trip element is operated manually. Is the duration of this operation shorter than the preset tripping time value, switches the device expediently automatically in the Initial state back, in which the preset Time delay value is reactivated. A Shutdown is only possible if one the triggering element is actuated for a sufficiently long period of time becomes. Brief actuations of the trigger link are therefore irrelevant. The one assigned to the power switch Device for the switch-off time delay preferably has an electronically controllable timer on the by means of an electrically connected to its control input connected switch must be started. After this This automatic reset button must start until the delay period expires in actuated Position held when an actual Switching off a corresponding supply circuit for the cooling device is to be reached. Otherwise, one only brief actuation of the push button ignored. The device preferably has one electronic counter based on a predetermined Delay time value is preset and during the Actuation of the push button used for counter control counts down from a preset value or up to increments a preset value and then the Switching off causes. A corresponding to the count Display value can be on an optical display device, in particular an LCD display. It is For example, it is possible to count down from one preset value, for example 5, during the Expiry of the time delay to another value, for example to count the value 0. After completing this Counting the device or an electrical operated device part switched off. It is useful thereby, additionally or alternatively besides the optical Display also an acoustic display to control that a signal during the expiring time delay value emits so that the visual display is not observed must and third parties can also take note. The Control of the expiry of the time delay time preferably made by a microprocessor which the corresponding display elements depending on the Pressing the push button controls. It is expedient, the status of the device or the concerned device part to be switched off in a memory store, especially in an EEPROM, which too Customer service purposes can be queried. The display of the Time delay value can also alternate with a temperature display in the same display and by means of the same display elements are made. The Device for delayed switch-off can be a Contain element that is in the manner of a monostable flip-flop or an R-C controlled Schmitt trigger is. It is advisable to press the key switch at the same time for restarting the supply circuit use, switching on without time delay he follows. With this structure, one becomes one electrical supply circuit switched on, in particular electronically trained or electronic controlled power switch after a manually triggered Start of a time delay device with a time delay switched on in the switched-off state, when the start condition of the time delay device beyond the preset time delay value is maintained. The activation of the power switch in contrast, the switch-off state is instantaneous. However, the unintentional switch-on should only be done under Additional conditions may also be possible Switch-on process analogous to the switch-off process with appropriate facilities can be controlled.

Die Erfindung ist nachfolgend anhand einer Prinzipskizze zusätzlich erläutert.The invention is based on a schematic diagram additionally explained.

Ein in der Zeichnung nicht näher dargestelltes Kühlgerät, insbesondere ein Gefrierschrank 1, weist eine Bedien- und Anzeigeblende 2 auf, die frontseitig unterhalb einer Arbeitsplatte 3 und oberhalb einer frontseitigen Gerätetür 4 angeordnet ist. In der Blende befindet sich ein Betätigungselement eines Tastschalters 5, mit dem das Gefriergerät unverzögert ein- aber verzögert ausgeschaltet werden kann, wenn das Betätigungselement des Tastschalters 5 über eine vorbestimmte Zeitverzögerungsdauer hinaus kontinuierlich manuell betätigt wird. In einem ebenfalls in die Blende integrierten Anzeigeelement 7, das insbesondere von einem Mikroprozessor gesteuert wird, erscheint im normalen Betriebsfall die im Kühlraum aktuell herrschende Temperatur. Wird jedoch der Tastschalter 5 betätigt, wird die Anzeige so umgeschaltet, daß zu Anfang ein der voreingestellten Abschaltzeitverzögerung entsprechender Wert angezeigt wird, der beispielsweise von einem Anzeigewert 5 während der Betätigungsdauer des Tastschalters 5 bis auf einen anderen Wert, beispielswert den Wert 0 zurückgezählt wird. Erst wenn dieser Wert erreicht wird, erfolgt die Abschaltung der Stromversorgung insbesondere für den Antrieb des Kältemittelkreislaufs. Gleichzeitig kann ein ebenfalls der Blende 2 zugeordnetes Warnelement 8 zumindest während des Ablaufs der Zeitverzögerung aktiviert sein und dabei ein akkustisches und/oder optisches Warnsignal abgeben. Wenn dieses Warnsignal auch während der Ausschaltphase des Versorgungsnetzes aufrechterhalten wird, kann mittels einer Quittungstaste 9 die Abschaltung dieses Warnsignals vorgenommen werden, wenn der Ausschaltvorgang tatsächlich bewußt gesteuert worden ist. Dieses Warnsignal kann auch dann aktiviert werden, wenn bei mangelhafter Kühlung des Kühlraums die vorgeschriebene niedrige Lagertemperatur nicht aufrechterhalten werden kann. Nach einer Ausschaltung des Netzschalters mittels des Tastschalters 5 kann durch erneutes Betätigen desselben vorzugsweise unter Ausnutzung des Mikroprozessors die erneute, insbesondere unverzögerte Einschaltung des Netzschalters erfolgen. Im übrigen ist die Alarmeinrichtung 8 nicht aktiviert, solange der normale Betriebszustand des Kühlgerätes besteht und der Tastschalter 5 unbetätigt ist.A cooling device, not shown in the drawing, in particular a freezer 1, has an operating and Display panel 2 on the front below one Worktop 3 and above a front door 4 is arranged. There is a in the aperture Actuator of a push button switch 5 with which Freezer switched on without delay but switched off with a delay can be when the actuator of the key switch 5 beyond a predetermined time delay period is continuously operated manually. In one also in the aperture integrated display element 7, in particular controlled by a microprocessor appears in the normal operating case is the one currently prevailing in the cold room Temperature. However, if the key switch 5 is actuated, the display switched so that one of the preset switch-off delay corresponding Value is displayed, for example from a Display value 5 during the actuation period of the Key switch 5 to another value, example value the value 0 is counted down. Only when this value is reached, the power supply is switched off especially for driving the refrigerant circuit. At the same time, an aperture 2 can also be assigned Warning element 8 at least during the course of Time delay must be activated and an acoustic and / or give an optical warning signal. If this Warning signal even during the switch-off phase of the Supply network can be maintained by means of a Acknowledgment button 9 to switch off this warning signal be made when the turn-off process actually has been consciously controlled. This warning signal can also then be activated if the cooling is insufficient Cold store the prescribed low storage temperature cannot be maintained. After a shutdown the power switch by means of the push button 5 can by actuating the same again, preferably using it the microprocessor the renewed, especially instantaneous The mains switch is switched on. Otherwise, the Alarm device 8 is not activated as long as the normal Operating condition of the cooling device exists and the Key switch 5 is not actuated.
