Description

Die Erfindung betrifft einen Temperaturregelschalter gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a temperature control switch according to the preamble of the first claim.

Es ist bei Temperaturregelschaltern dieser Art ganz allgemein bekannt, am Anfang oder auch am Ende des möglichen Verstellweges einen Ein-Aus-Schaltkontakt zu betätigen, während über den übrigen Verstellweg die Einstellvorrichtung frei verdreht oder verschoben werden kann, um unterschiedliche Schalttemperaturen für einen temperaturabhängig betätigbaren Schaltkontakt vorzugeben. Ein so ausgebildeter Temperaturregelschalter ist für die durchgehende Temperaturregelung über einen vorbestimmten Temperaturbereich geeignet. Sollen in einem Gerät jedoch zwei unterschiedliche Temperaturbereiche überstrichen werden, dann sind auch zwei getrennte Temperaturregelschalter erforderlich.It is very well known in temperature control switches of this type to actuate an on-off switch contact at the beginning or at the end of the possible adjustment path, while the adjustment device can be freely rotated or shifted over the remaining adjustment path by different switching temperatures for a temperature-dependent switch contact to specify. A temperature control switch designed in this way is suitable for continuous temperature control over a predetermined temperature range. However, if two different temperature ranges are to be covered in one device, then two separate temperature control switches are also required.

Aufgabe der Erfindung ist es, einen Temperaturregelschalter gemäß dem Oberbegriff des ersten Anspruches zu schaffen, der zwei getrennte Temperaturregelbereiche aufweist und dabei in einfacher Weise bedienbar und herstellbar ist.The object of the invention is to provide a temperature control switch according to the preamble of the first claim, which has two separate temperature control ranges and can be operated and manufactured in a simple manner.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des ersten Anspruchs.This problem is solved by the characterizing features of the first claim.

Durch die überfahrbare Rastvorrichtung wird somit der gesamte Verstellweg der Einstellvorrichtung in Verstellstrekken mit entsprechenden Temperaturregelbereichen aufgeteilt. Um von einem Temperaturregelbereich zum anderen zu gelangen, muß daher erst die Rastvorrichtung überwunden werden. Fehleinstellungen können somit nicht unbeabsichtigt, z.B. durch . Anstoßen an die Einstellvorrichtung erfolgen. Dabei kann mit dem üblichen Aufwand für einen Temperaturregelschalter in zwei getrennten Temperaturregelbereichen eine Regelung durchgeführt werden, ohne dabei elektrische oder mechanische Umschalteinrichtungen verwenden zu müssen. Die Anwendung eines so ausgebildeten Temperaturregelschalters ist besonders vorteilhaft in Kühlschränken, wenn sie einerseits in einem Temperaturbereich von z.B. 0°C bis plus 6°C für die übliche Kühlung und andererseits zur Frischhaltung von Gemüse und Südfrüchten in einem Temperaturbereich von z.B. 6°C bis plus 15°C betrieben werden sollen.The entire locking path of the adjustment device is thus divided into adjustment paths with corresponding temperature control ranges by the drive-over locking device. In order to get from one temperature control range to another, the latching device must first be overcome. Incorrect settings cannot be unintentionally, e.g. by . Bump into the adjusting device. With the usual effort for a temperature control switch, control can be carried out in two separate temperature control ranges without having to use electrical or mechanical switching devices. The use of a temperature control switch designed in this way is particularly advantageous in refrigerators if, on the one hand, it is in a temperature range of e.g. 0 ° C to plus 6 ° C for the usual cooling and on the other hand for keeping vegetables and tropical fruits fresh in a temperature range of e.g. 6 ° C to plus 15 ° C should be operated.

Vorteilhafte Ausgestaltungen sind den weiteren Ansprüchen zu entnehmen.Advantageous refinements can be found in the further claims.

Die Erfindung ist nachfolgend anhand der Zeichnungen von Ausführungsbeispielen näher erläutert.The invention is explained in more detail below with reference to the drawings of exemplary embodiments.

Es zeigen:

  • Fig. 1 den prinzipiellen Aufbau eines Temperaturregelschalters, bei dem die Verstellstrecken der Kurvenbahn gleiche Neigung aufweisen und
  • Fig. 2 eine Prinzipdarstellung eines Temperaturregelschalters, bei dem die beiden Verstellstrecken gegenläufige Neigung aufweisen.
Show it:
  • Fig. 1 shows the basic structure of a temperature control switch in which the adjustment paths of the cam track have the same inclination and
  • Fig. 2 is a schematic diagram of a temperature control switch, in which the two adjustment paths have opposite inclinations.

Ein Temperaturregelschalter 1 ist mit einem Ein-Aus-Schaltkontakt 2 und mit einem temperaturabhängig gesteuerten Schaltkontakt 2 versehen.A temperature control switch 1 is provided with an on-off switch contact 2 and with a temperature-dependent controlled switch contact 2.

Dem Ein-Aus-Schaltkontakt 2 ist ein Schaltstift 4 zugeordnet, der mit einer Nockenbahn 5 zusammenwirkt. In der Nockenbahn 5 ist eine Vertiefung 6 als Nocken vorgesehen. Der Schaltkontakt 3 ist mit einem Tastfinder 7 ausgestattet, der auf einer Kurvenbahn läuft. Die Nockenbahn 5 und die Kurvenbahn sind auf einer gemeinsamen Welle befestigt, die von Hand verdrehbar ist, wodurch eine Einstellvorrichtung für den Schaltkontakt 3 und den Ein-Aus-Schaltkontakt 2 gebildet ist.A switching pin 4 is associated with the on-off switching contact 2 and cooperates with a cam track 5. A recess 6 is provided in the cam track 5 as a cam. The switch contact 3 is equipped with a touch finder 7, which runs on a cam track. The cam track 5 and the cam track are fastened on a common shaft which can be rotated by hand, as a result of which an adjusting device for the switching contact 3 and the on-off switching contact 2 is formed.

Gemäß Fig. 1 weist die Kurvenbahn über eine in ihrem mittleren Bereich vorgesehen Verstellstrecke 9 einen konstanten Radius auf. Diese Verstellstrecke 9 erstreckt sich dabei über einen Drehwinkel 10, der durch die Länge der Vertiefung 6 in Umfangsrichtung vorgegeben ist. An die Verstellstrecke 9 mit konstantem Radius schließt sich in der einen Drehrichtung der Kurvenbahn eine weitere Verstellstrecke 11 an, deren Radius bis zu einem Endanschlag 12 hin abnimmt, während sich in der Gegendrehrichtung an die Verstellstrecke 9 eine Verstellstrecke 13 mit zunehmendem Radius anschließt. Die Verstellstrecke 13 reicht bis zu einem Endanschlag 14.1, the cam track has a constant radius over an adjustment section 9 provided in its central region. This adjustment path 9 extends over an angle of rotation 10, which is predetermined by the length of the recess 6 in the circumferential direction. The adjustment path 9 with a constant radius is followed by a further adjustment path 11 in one direction of rotation of the cam track, the radius of which decreases as far as an end stop 12, while an adjustment path 13 with increasing radius adjoins the adjustment path 9 in the opposite direction of rotation. The adjustment path 13 extends to an end stop 14.

In der dargestellten Ausgangsstellung des Temperaturregelschalters 1 gemäß Fig. 1 ist der Schaltstift 4 in die Vertiefung 6 der Nockenbahn 5 eingefallen und der Ein-Aus- . schalter 2 befindet sich zwangsläufig in seiner Ausschaltstellung. Die Vertiefung 6 bildet dabei zusammen mit dem federbelasteten Schaltstift 4 eine Rastvorrichtung, die in beiden Drehrichtungen überfahrbar ist. Sobald demnach der Schaltstift 4 über seine schrägen Flanken durch die Kanten der Vertiefung 6 auf die mit konstantem Radius weiterlaufende Nockenbahn 5 angehoben ist, wird der Ein-Aus-Schaltkontakt 2 in seiner Einschaltstellung bewegt.In the illustrated starting position of the temperature control switch 1 according to FIG. 1, the switching pin 4 has fallen into the recess 6 of the cam track 5 and the on-off. switch 2 is inevitably in its off position position. The recess 6 forms, together with the spring-loaded switching pin 4, a locking device which can be driven over in both directions of rotation. Accordingly, as soon as the switching pin 4 is raised over its inclined flanks by the edges of the recess 6 onto the cam track 5 which continues with a constant radius, the on-off switching contact 2 is moved in its switched-on position.

Wenn der Schaltstift 4 in die Vertriefung 6 eingefallen ist, befindet sich der Tastfinger 7 auf der Verstellstrecke 9, deren Radius dem temperaturgesteuerten Schaltkontakt 3 eine Schalttemperatur von beispielsweise plus 6°C vorgibt. Der Meßfühler 15 des Schaltkontaktes 3 befindet sich vorzugsweise in einem Kühlgerät, dessen Temperatur im Betrachtungsaugenblick niedriger als plus 6°C sein soll. Daher ist in diesem Fall der Schaltkontakt 3 geöffnet. Wird nun an der Einstellwelle 8 eine Verdrehung der Nockenbahn 5 und der fest damit verbundenen Kurvenbahn so vorgenommen, daß die Verstellstrecke 11 der Kurvenbahn unter dem Tastfinger 7 gleitet, dann wird zunächst der Ein-Aus-Schaltkontakt 2 in seine Einschaltstellung gebracht und dem temperaturgesteuerten Schaltkontakt 3 eine Solltemperatur vorgegeben, die beispielsweise bis auf 0°C abgesenkt wird, wenn der Tastfinger 7 im Bereich des Endanschlages 12 angelangt ist. Dort weist die Verstellstrecke 11 ihren geringsten Radius auf. Sobald die Isttemperatur am Meßfühler 15 die von der Verstellstrecke 11 vorgegebene Temperatur unterschreitet, wird der Schaltkontakt 3-geschlossen und beispielsweise das Kühlaggregat des Kühlgerätes eingeschaltet. Nach Erreichen der Solltemperatur schaltet der Schaltkontakt durch die Wirkung des Meßfühlers 15 das Kühlaggregat wieder ab. Der Bereich von plus 6°C bi-s 0°C entspricht dabei dem Temperaturbereich eines Kühlschrankes für Normalkühlung.When the switching pin 4 has fallen into the recess 6, the touch finger 7 is located on the adjustment path 9, the radius of which specifies a switching temperature of, for example, plus 6 ° C. for the temperature-controlled switching contact 3. The sensor 15 of the switch contact 3 is preferably located in a cooling device, the temperature of which should be lower than plus 6 ° C at the moment of observation. Therefore, the switch contact 3 is open in this case. If the cam track 5 and the cam track firmly connected to it are rotated on the setting shaft 8 such that the adjustment path 11 of the cam track slides under the finger 7, then the on-off switch contact 2 is first brought into its switch-on position and the temperature-controlled switch contact 3 specifies a target temperature, which is reduced, for example, to 0 ° C. when the touch finger 7 has reached the area of the end stop 12. There the adjustment path 11 has its smallest radius. As soon as the actual temperature at the sensor 15 falls below the temperature specified by the adjustment path 11, the switch contact 3 is closed and, for example, the cooling unit of the cooling device is switched on. After reaching the target temperature, the switching contact switches the cooling unit off again through the action of the sensor 15. The range of plus 6 ° C to 0 ° C corresponds to the temperature range of a refrigerator for normal cooling.

Soll das Kühlgerät in einem Temperaturbereich von beispielsweise plus 6°C bis plus 15°C betrieben werden, um Gemüse und Südfrüchte oder dergl. lagern zu können, dann wird die Einstellwelle 8 unter Überfahren der Rastvorrichtung 4, 6 und der Verstellstrecke 9 so lange gedreht, bis die Verstellstrecke 13 der Kurvenbahn unter den Tastfinger 7 gelangt. Durch den zunehmenden Radius dieser Verstellstrecke 13 wird auch über den Tastfinger 7 dem temperaturgesteuerten Schaltkontakt 3 eine höhere Sollschalttemperatur vorgegeben, auf die das Kühlgerät mit Hilfe des Meßfühlers 15 in üblicher Weise nachgeführt wird.If the cooling device is to be operated in a temperature range of, for example, plus 6 ° C. to plus 15 ° C. in order to be able to store vegetables and tropical fruits or the like, then the setting shaft 8 is rotated as long as it travels over the locking device 4, 6 and the adjustment distance 9 until the adjustment path 13 of the cam path reaches under the finger 7. Due to the increasing radius of this adjustment path 13, the temperature-controlled switching contact 3 also specifies a higher setpoint switching temperature via the touch finger 7, to which the cooling device is tracked in the usual way with the aid of the sensor 15.

Gemäß Fig. 2 ist bei sonst gleichem Aufbau die Form der Kurvenbahn so geändert, daß die beiden Temperatureinstellbereiche ihren jeweiligen Maximalwert dann aufweisen, wenn sich der Tastfinger 7 im Bereich der Endanschläge 12 bzw. 14 befindet. Hierzu weist die Verstellstrecke 9 über den Drehwinkel 10 eine Steigung auf, die der Temperaturdifferenz zwischen den jeweiligen niedrigsten Temperaturen der beiden Temperaturregelbereiche entspricht. Ausgehend von der dargestellten Stellung, in der die Rastvorrichtung wirksam und der Ein-Aus-Schaltkontakt 2 das Kühlaggregat ausgeschaltet hat, wird beim Verdrehen der Einstellwelle 8 der Ein-Aus-Schaltkontakt 2 geschlossen und über die Verstellstrecke 11 bzw. die Verstellstrecke 13 zunächst der niedrigste Solltemperaturwert des jeweils zu überstreichenden Temperaturbereiches vorgegeben. Hierdurch wird erreicht, daß ausgehend von der Nullstellung im Bereich der Rastvorrichtung 4, 6 in beiden Drehrichtungen die Solltemperatur von den jeweils niedrigsten auf den zugehörigen höchsten Temperaturwert verstellt wird. Selbstverständlich ist es auch möglich, dem jeweils kleineren Radius eine höhere Solltemperatur zuzuordnen.According to FIG. 2, the shape of the cam track has been changed so that the two temperature setting ranges have their respective maximum value when the stylus 7 is in the area of the end stops 12 and 14. For this purpose, the adjustment path 9 has an incline over the angle of rotation 10, which corresponds to the temperature difference between the respective lowest temperatures of the two temperature control ranges. Starting from the position shown, in which the latching device is effective and the on-off switch contact 2 has switched off the cooling unit, the on-off switch contact 2 is closed when the setting shaft 8 is rotated, and first of all via the adjustment path 11 or the adjustment path 13 Lowest target temperature value of the temperature range to be covered is specified. This ensures that, starting from the zero position in the area of the latching device 4, 6, the setpoint temperature is adjusted from the lowest to the associated highest temperature value in both directions of rotation. Of course, it is also possible to assign a higher target temperature to the smaller radius.
