overheating esqhutjs for electrical »arm devices * especially for hangers ·» iron"

Electric heating devices, especially irons, form a branduad "In special adverse circumstances, there is also a risk of death * if they are not switched off after use Kettle with a froekengehutzutz and iron with fempearattcftreglern manufactured * which significantly reduce the risk of fire. But such devices are far more expensive than the common, used, simple ones Designs and for the large cash register the purchase it is unaffordable. Further Sled facilities are known to have connector plugs on the ea - dea heaters and are equipped with elnezs overheating protection * These, however, are liable for the lack of unsafe heat transfer to * "." - - ■. - -. -

Me invention has set the task of creating an overheating protection that can be manufactured cheaply. entwiekela, which uses so little saunas »that it can be accommodated in normal electrical appliances, especially in irons *, and can also be retrofitted into existing appliances»

Me! Solution of this problem is based on dea thoughts, one or "if space is sufficiently available * also to be installed both cables at the entry point into the device to interrupt and in the Tfaterbrechungsstelle overheat protection described below, ä & B he la machine throws himself accommodated. The protection consists essentially of a switching pin which is movable in its longitudinal direction and which is held in place by a strip of thermal bimetal and together with this directly forms a switch through which the heating current of the heating device flows. When the permissible temperature is exceeded, the bimetallic strip releases the switch pin, which snaps back through a spring and thereby interrupts the supply line.

The switch pin is at its end pointing into the interior of the device provided with a notch or a Yoreprung and a point * die to snap-in the bimetallic strip * Sleser can be used to The reclosing is carried out with an inclined approach will also consist of another fiaterial and with the.

In most cases, the heating devices to connect to are the rag Equipped with the tekaanten device connector. In these cases the switch pin and the spring are inserted into one or both connector plugs Device plug-in device installed so that it lies in its longitudinal axis and with a tip held in "biaetell strips" into the interior of the Device protrudes. One end of the bimetallic strip is connected to an insulating * stfick feet * that lies behind the device inside the device. 4a ÄiiBiea Sade is also the connection to "radiators of the fferätee firmly connected. The connector pin is designed as a screw sleeve, which is unscrewed from the holding pin must * Or the tip of the connector pin has an opening through which the switch pin can be opened with a small screwdriver or After overheating and cooling down the device, put the plug in his Operating position can be pushed back «You opening becomes more expedient Way closed by a screw, a removable sap or the like, so that no foreign bodies can penetrate into the opening impede movement of the switch pin «Switching on again is completely harmless, as the strap handles required for this only after removal the device plug-in can be carried out from the plug part of the device,

In the case of heating devices with a permanently installed supply line, switch pin and Bimetal strips built into an insulating body of the heating device, the can also be a part of the handle * The bimetallic strip is attached in such a way that it is heated by the heat in the device and the Switching point is inside the device * The mode of operation is the same those described for devices with a device plug. To switch it on again, the switch pin is provided with an insulating part at its end pointing outwards, which is appropriately shaped like a button and in the event of overheating emerges from the insulating body «

The drawing illustrates two example embodiments of the invention * It shows in Fig. 1 the longitudinal section of an overheating protection for device · with device plug connection in switch-on position »in Fig * 2 the same in Ausachaltstellung, in Fig. 3 the longitudinal section ei &es; Overheating non-protection for devices with a permanently installed supply line in « Switch position and in Fig * 4 the tip of the switchgear with the notch part of the bimetallic strip.
