Description

Switching device for the outside temperature-dependent setting of a Thermostats in a heat storage furnace The invention relates.nich to a switching device For setting depending on the outside temperature, record the storage core temperature Thermostats in at least one heat storage heater.

- In the event of such a switchgear, it is known to expose an encapsulated bimetal switch with a changeover contact and heating resistor to the outside temperature. The resistance creates a temperature in the capsule that allows the switch to switch over. As a result, the resistor is switched off and a voltage is applied to the resistors for external heating of the thermostats in heat storage cells $ The higher the outside temperature here, the shorter the time until switching and the longer the cool-down time to switch it on again . the resisted. As a result, the electrical resistors on the thermostats in the heat storage furnace are supplied with a higher output per unit of time and the final switching temperature is already reached at low memory core temperatures can be and thereby changed its switching characteristics. In addition, for sufficient external heating of the thermostat, a relatively high output is required, so that with a large number of connected heat storage devices, the bimetallic contact wears out quickly because of its high switching frequency.

The object of the invention is a switching device of the receipts Established so that the external heating of the thermostats in the heat storage stoves and a wonderfully impulsive contact is omitted.

The solution to this object is, according to the invention, that a switch, the switching point of which changes depending on the outside temperature, switches a device. which readjusts the switch up to the switching point and that a setting device is switched in parallel with the back-up device which adjusts the Thermettten in the lärmeepelcherofen at the same time as the back-up device- "The setting of the thermostats in the heat transfer furnaces is therefore » obanieohv so that a thermal overload of the * Therikonteten in VR- rmenpeich.erbten b.ei ungUtetigen Teiäporaturverhältnionen between Außentemp'eratur Speicherkernteaparatur and can no longer occur and the saddle temperaturgenteuerte - 1-th switched on only when Außentemperaturnehwankungen.

Further advantageous details of the invention are shown below with the aid of the drawing of an exemplary embodiment, but are still raging. A temperature-controlled switch 19, for example Fluid expansion regulator with one of the outside temperature temperature external temperature sensor 2 has a contact auf-der In the rest position of switch 1 until it is range of the low outside temperature to be recorded closed-iat. By turning a readjusting axle 4, you can the contact 3 is opened # whereby the necessary rotation from the rest position up to opening with increasing Outside temperature increases, the contact 3 iot via a switching clock 5 can be attached to the voltage and is connected in series with a Interrupt 2Untakt 6 in the circuit oinee sheet magneti .7.

The pawl 11 is held in engagement with the toothing of the gear wheel 9 against the action of an actuator spring 13 by a pull magnet 12, which is also connected to the time switch 5 . The interrupter contact 6 can be coupled to the indexing pawl 8 , or it can be designed as a self-interrupting bimetal switch. The locking pawl 11 is connected to a lever 14 by means of which the Fortechalt pawl 8 can be pivoted out of the range of action of the toothing on the gear wheel q. The adjustment device for de-n-Thermontaten 15 in the Wäriaeapeleberofen 16 is also designed as a step controller to simplify production, the electromagnet 7 of which is parallel 1 to the electromagnet 7 in the adjustment device for the switch 1 . % ,, With the gear wheel 9 the thermostat is set from the rest position to lower Sebelt temperatures. The operating mode of the switching device is as follows: Before the timer 5 applies voltage to the switching device, the release springs 13 at the step-by-step switches have brought the pawls 11 and the stepping pawls 8 out of the range of action of the corresponding gears q, so that the return springs 10 could bring the temperature-dependent switch 1 or the thermostat 15 to their rest position. If voltage is now applied to this switching device by the timer 5 at the beginning of the low tariff period, then the Zugmagneteri 12 bring the pawl 11 and the for, t ",) chalt pawls 8 into engagement with the toothing of the gears Ani: enocaen it has an awkato temperature below that lower greartomperaturo that imit this sohaiteinrichtung should be recorded there = is contact 3 goded, oodas the stepping mechanism 4-way adjustment device for the Switch 1 does not work when switched on by the bucket clock 5 anliLaft -.- Daduroh also remain dl * step controllers for -Einstellug'der thermostats 15 : La the heating kiln 16 In their resting place and the Wäreeopäiaheröfen 16 have been tea set on your floor by the thermostat often 15 temperature heated. On the other hand, an outside temperature above the lower limit temperature is quite right because if contact 3 is closed and the step switching mechanism for switch 1 is switched on via interrupter contact 6 , contact 3 is opened via adjustment axis 4. At the same time, the display salting mill in the heat storage area has been switched on by the same number of teeth outside of its rest position, and as a result the ThermastL-t 15 has been adjusted to a lower display temperature.
