Abstract

The electric oven has a cooking space (3) behind the door (4) which is heated by an element (5). To protect its housing (1) and neighbouring furniture and esp. electronic controls, the fan (6) suitably positioned on the housing is operated (7) under electronic control from a temp. sensor (8) on the metallic housing (9) of an interior lamp (10) on the back wall (11). The temp. sensor is a PTC resistor providing a signal to start the fan when the temp. exceeds a preset level. The heat source represented by the oven and its lamp is accurately monitored so as to keep the fan running for as long as overheating is to be expected.

Description

Die vorliegende Erfindung bezieht sich auf einen Back-/Bratofen mit Ofenheizung und mit zumindest einer Beleuchtungseinrichtung zum Beleuchten des Ofenmuffel-Innenraums sowie mit einem thermostatgesteuerten Motorlüfter für die Gehäusekühlung.The present invention relates to a baking / roasting oven with oven heating and with at least one lighting device for illuminating the interior of the oven muffle and with a thermostatically controlled motor fan for cooling the housing.

Es ist allgemein üblich, die Ansteuerung der Heizelemente einer Ofenmuffelheizung über Thermostaten vorzunehmen, da damit für das Gargut gut beherrschbare Behandlungsbedingungen erzielt werden. Je nach Garungs- bzw. Behandlungsart des Gargutes können entsprechende Garungstemperaturen ausgewählt werden, deren Einhaltung durch den Thermostaten, dessen Thermofühler naheliegenderweise innerhalb der Ofenmuffel und in zweckmäßigerweise zu den Heizquellen ausgerichtet angeordnet ist.It is common practice to control the heating elements of a muffle heater by means of thermostats, since treatment conditions which are easy to control for the food to be cooked are thereby achieved. Depending on the type of cooking or treatment of the food to be cooked, appropriate cooking temperatures can be selected, compliance with which is arranged by the thermostat, whose thermal sensor is obviously arranged within the oven muffle and expediently aligned with the heating sources.

Zum einen zum Schutze von dem Back-/Bratofen benachbarten Möbeln bzw. dem Einbaukorpus bei Einbau-Back-/Bratöfen und zum anderen zum Schutze von zum Einsatz gebrachten elektronischen Bauelementen gegen Überwärmung oder Übererhitzung ist es bekanntgeworden, Motorlüfter einzusetzen, die in Verbindung mit geeigneten Luftführungswegen, insbesondere die elektronischen Bauelemente aber auch das Umfeld der Ofenmuffel durch den erzeugten Luftstrom kühlen. Derartige Lüftersysteme sind insbesondere auch bei Öfen erforderlich, welche zur Reinigung der Ofenmuffel auf pyrolytische Selbstreinigung zurückgreifen. Zur Ansteuerung des Lüftermotors werden bei bekannten Anordnungen unterschiedliche Kriterien herangezogen. Beispielsweise kann es ausreichend sein, und dies ist häufig bei reinen Mikrowellenherden der Fall, daß der Lüftermotor lediglich während der Einschaltzeit von Heizleistungsvorgängen angesteuert und betrieben wird. Es hat sich aber auch als zweckmäßig erwiesen, nach Laufzeiten für die Ansteuerung eines Motorlüfters nach einer Betriebszeit des Back-/Bratofens zu realisieren. Des weiteren ist es auch bekannt geworden, Thermofühler zum Einsatz zu bringen, welche an zweckmäßig erachteten Stellen in den zu kühlenden problematischen Bereichen die Temperatur erfassen. In diesem Zusammenhang ist es auch bekannt, die Ofenmuffel-Temperatur selbst zu erfassen, beispielsweise indem an die Wandung des Back-/Bratraumes ein Metallbügel herangeführt ist, der mit einem temperaturabhängig schaltenden Schalter zur Ansteuerung für den Motorlüfter in Verbindung steht.On the one hand to protect the furniture or the built-in body in the case of built-in baking / roasting ovens, and on the other hand to protect electronic components used against overheating or overheating it has become known to use motor fans which, in combination with suitable air ducts, in particular the electronic components, also cool the area around the furnace muffle by the air flow generated. Fan systems of this type are also required in particular in furnaces which use pyrolytic self-cleaning to clean the furnace muffle. In known arrangements, different criteria are used to control the fan motor. For example, it may be sufficient, and this is often the case with pure microwave ovens, that the fan motor is only controlled and operated during the heating power processes during the switch-on time. However, it has also proven expedient to implement after operating times for the control of a motor fan after an operating time of the baking / roasting oven. Furthermore, it has also become known to use thermocouples which measure the temperature at points deemed expedient in the problematic areas to be cooled. In this context, it is also known to detect the furnace muffle temperature itself, for example by leading a metal bracket to the wall of the baking / roasting space, which is connected to a temperature-dependent switch for controlling the motor fan.

Aufbauend auf diesem Stand der Technik ist es Aufgabe der vorliegenden Erfindung, eine Ansteuerung für einen Motorlüfter zur Gehäusekühlung bereitzustellen, die zum einen funktionstüchtig und zum anderen möglichst einfach ist.Building on this prior art, it is the object of the present invention to provide a control for a motor fan for cooling the housing, which is on the one hand functional and on the other hand as simple as possible.

Eine Ansteuerung für einen Motorlüfter zur Gehäusekühlung, die diesen Anforderungen gerecht wird, ist erfindungsgemäß dadurch gekennzeichnet, daß der Thermofühler der Thermostatsteuerungs-Einheit für den Motorlüfter kontaktiert ist mit der Wandung eines aus der Ofenmuffel nach außen ragenden Gehäuseteils der Ofenmuffel-Beleuchtungseinrichtung.A control for a motor fan for cooling the housing, which meets these requirements, is characterized according to the invention in that the thermocouple of the thermostat control unit for the motor fan is contacted with the wall of a housing part of the furnace muffle lighting device protruding outwards from the furnace muffle.

Eine Thermostatsteuerung für den Motorlüfter zur Gehäusekühlung nach den erfindungsgenäßen Merkmalen zeichnet sich dadurch aus, daß die Montage- und Ankopplung des Thermofühlers dieser Thermostat-Steuerungseinheit an der aus der Ofenmuffel nach außen abstehenden Gehausewandung der für die Muffelinnenbeleuchtung dienenden Beleuchtungseinrichtung ohne besondere zusätzliche Maßnahmen besonders einfach und effizient ist. Der Thermofühler braucht lediglich, z.B. unter Verwendung einer Befestigungslasche, an die aus Sicherheitsgründen, Kühlungsgründen und Wärmebelastungsgründen metallische Gehäusewandung der Beleuchtungseinrichtung von außen in Verbindung gebracht werden. Über die Gehäusewandung der Beleuchtungseinrichtung wird an den Thermofühler gesichert die Temperatur der Muffelwandung herangeführt und zusätzlich wird der Thermofühler durch die Heizleistung der Beleuchtungseinrichtung ebenfalls mit Wärmeenergie beaufschlagt. Das hat zur Folge, daß bereits kurz nach Einschalten der Backofenbeleuchtung der Thermofühler anspricht und über die nachgeschaltete Thermostatsteuerungs-Einheit den Motorlüfter für die Gehäusekühlung in Betrieb setzt und diese Betriebsweise auch über die Heizphasen hinaus mindestens solange aufrecht erhält, bis die Backofenbeleuchtung abgeschaltet wird.A thermostat control for the motor fan for cooling the housing according to the features according to the invention is characterized in that the mounting and coupling of the thermocouple of this thermostat control unit to the housing wall of the muffle interior lighting of the lighting device serving for the muffle interior lighting is particularly simple and without special measures is efficient. The thermal sensor only needs, e.g. using a fastening tab to which, for safety reasons, cooling reasons and heat load reasons, metallic housing walls of the lighting device are connected from the outside. The temperature of the muffle wall is securely brought up to the thermal sensor via the housing wall of the lighting device and, in addition, the thermal power of the lighting device is also subjected to thermal energy. As a result, the thermal sensor responds shortly after the oven lighting is switched on and the motor fan for the housing cooling is activated via the downstream thermostat control unit and maintains this mode of operation beyond the heating phases at least until the oven lighting is switched off.

Da die Backofenbeleuchtung regelmäßigerweise länger eingeschaltet ist als die Backofenbeheizung, ist durch die erfindungsgemäße Anordnung des Thermofühlers dieser mit höchster Wahrscheinlichkeit an der am wärnsten verbliebenen Stelle der Backofenmuffel, so daß der thernostatgesteuerte Lüftermotor mit sehr hoher Sicherheitsgarantie genügend ausdauernd kühlt. Eine gesonderte Zeitsteuerung des Motorlüfters bzw. besondere Maßnahmen zur Nachlaufsteuerung können deshalb entfallen.Since the oven lighting is regularly switched on longer than the oven heating, the arrangement according to the invention of the thermal sensor means that it is most likely to be at the warmest point of the oven muffle, so that the thernostat-controlled fan motor with a very high safety guarantee is sufficiently durable cools. A separate time control of the motor fan or special measures for run-on control can therefore be omitted.

Nach einer bevorzugten Ausgestaltung des vorliegenden Erfindung ist der Temperaturfühler ein temperaturabhängig stark veränderlicher Widerstand mit positivem Temperatur-Koeffizienten-Verhalten. Der sich entsprechend der an der Wandung der Ofenbeleuchtung vorhandenen Temperatur ergebende Widerstandswert des Temperaturfühlers wird bei Erreichen eines festen Widerstands-Schwellwerts zur Ansteuerung des Motorlüfters ausgewertet und bei Unterschreiten dieses Schwellwertes wird der Motorlüfter wieder abgeschaltet, da dann davon auszugehen ist, daß gesichert keine problematische Temperatur in dem zu kühlenden Bereich vorhanden ist, da keine Wärmenachfuhr aus wärmeren Bereichen mehr zu erwarten ist.According to a preferred embodiment of the present invention, the temperature sensor is a temperature-dependent, strongly variable resistor with a positive temperature-coefficient behavior. The resistance value of the temperature sensor resulting from the temperature on the wall of the furnace lighting is evaluated when the resistance of the motor fan is reached and the motor fan is switched off when the temperature falls below this threshold, since it can then be assumed that no problematic temperature is guaranteed is present in the area to be cooled, since heat supply from warmer areas is no longer to be expected.

Ein nach den Merkmalen der Erfindung ausgestattetes Ausführungsbeispiel ist im folgenden kurz beschrieben. Es zeigen:

An embodiment equipped according to the features of the invention is briefly described below. Show it:
Fig. 1
schematized a muffle of a household stove in a side view
Fig. 2
also schematically shows a partial view in the area of the oven lighting.

In der Fig. 1 ist in schematisierter Ansicht ein Einbau-Backofen dargestellt, dessen aus einer Muffel 2 gebildeter Back-/Bratraum 3 durch eine Gerätetür 4 verschlossen ist. Der Back-/Bratraum 2 wird von einem Heizkörper 5 beheizt. Um das Gehäuse des Einbau-Backofens 1 und somit auch die benachbarten Möbel sowie insbesondere auch elektronische Steuereinrichtungen von hohen bzw. zu hohen Temperaturen zu schützen, ist der Einbau-Backofen 1 mit einem Motorlüfter 6 versehen, der an geeigneter Stelle im Backofengehäuse angeordnet ist. Der Lüftermotor 6 wird durch eine Thermostatelektronik 7 angesteuert, wobei das Ansteuersignal von einem Thermosensor 8 geliefert wird, welcher an dem Gehäuse 9 einer Backofenbeleuchtung 10 angeflanscht ist. Zum einen steht dieses Gehäuse 9, welches insbesondere aus thermischen Gründen üblicherweise aus Metall besteht, mit der Muffelwandung 11 des Back-/Bratraums 2 in thermischer Verbindung und es ist auch der im Inneren des Back-/Bratraums 2 herrschenden Temperatur ausgesetzt.In Fig. 1, a built-in oven is shown in a schematic view, the baking / roasting space 3 formed from a muffle 2 is closed by an appliance door 4. The baking / roasting space 2 is heated by a radiator 5. Around the housing of the built-in oven 1 and thus also the neighboring furniture and in particular also electronic control devices of high or too high temperatures protect, the built-in oven 1 is provided with a motor fan 6, which is arranged at a suitable point in the oven housing. The fan motor 6 is controlled by thermostat electronics 7, the control signal being supplied by a thermal sensor 8 which is flanged to the housing 9 of an oven light 10. On the one hand, this housing 9, which, for thermal reasons in particular, usually consists of metal, is in thermal connection with the muffle wall 11 of the baking / roasting space 2 and is also exposed to the temperature prevailing inside the baking / roasting space 2.

Bei Überschreiten einer vorgegebenen Temperatur im Bereich des Gehäuses 9 der Beleuchtungseinrichtung 10 wird vom Thermofühler 8, welcher als starkt widerstandsveränderlicher Widerstand mit positiver Temperaturcharakteristik (PTC) ausgebildet ist, ein elektrisch auswertbarer Wert an die Thermostatsteuerschaltung 7 abgegeben, so daß diese den Motorlüfter 6 in Gang setzt, wodurch für ausreichende Kühlung in Gerätegehäuse gesorgt wird. Die das Gerätegehäuse erwärmende Wärmequelle ist der Back-/Bratraum 2 und als Übergangsstelle dessen 11. Da diese Wärmequelle über das Gehäuse 9 der Beleuchtungseinrichtung 10 annährend unverfälscht erfaßt wird und zusätzlich noch die Wärme der Beleuchtungseinrichtung 10 selbst erfaßt wird, ist sichergestellt, daß der Motorlüfter 6 garantiert solange in Betrieb ist, wie erhöhte Wärme erwartet werden kann.When a predetermined temperature in the area of the housing 9 of the lighting device 10 is exceeded, the thermocouple 8, which is designed as a strongly variable resistor with a positive temperature characteristic (PTC), outputs an electrically evaluable value to the thermostat control circuit 7 so that the motor fan 6 is started sets, which ensures sufficient cooling in the device housing. The heat source that heats the device housing is the baking / roasting space 2 and, as a transition point, its 11th place. Since this heat source is detected almost unadulterated via the housing 9 of the lighting device 10 and additionally the heat of the lighting device 10 itself is detected, it is ensured that the motor fan 6 is guaranteed to be in operation as long as increased heat can be expected.

Mit Hilfe dieser Maßnahmen ist es also möglich, auf eine gesonderte Nachlaufsteuerung für den Motorlüfter 6 zu verzichten.With the help of these measures, it is therefore possible to dispense with a separate run-on control for the motor fan 6.
