Wiring system for electrically operated devices comprising heating resistances
| Details |
Inventors: Roth, Moshe;

Attorney, Agent or Firm:
In the disclosed heater device, a thermostatic control is connected in series with a heating resistance across two power junctions. An incandescent lamp and a glow lamp are connected in series between the junctions while the common point between the lamps is connected to the common point between the switch and the resistance. When the thermostatic switch opens in response to heat it turns on the glow lamp; when it closes it turns on the incandescent lamp. |
|
DETAILED DESCRIPTION What is claimed is: 1.
A heating arrangement comprising: first and second junctions connectable to a power source, a heating resistance having first and second terminals, a thermostatic control switch in series with the second terminal of the resistance, and two optical signals, one being an incandescent lamp and the second a gas filled glow lamp, each having first and second terminals and being arranged and positioned such that one terminal of the incandescent lamp is directly connected to the second terminal of said resistance, a connection from the first terminal of the incandescent lamp to the first terminal of the glow lamp, the second terminal of the incandescent lamp being connected to one of the junctions, a connection from the one of the junctions to the first terminal of the resistance, the second terminal of the glow lamp being connected to the other of said junctions and the other of said junctions being connected to the thermosttic switch, and a supplemental switch in series with said resistance and one of said functions.
Description:
BACKGROUND OF INVENTION The present invention relates to a wiring system for electrically controlled devices, such as domestic cooling apparatus, flat irons, grillers and so on, and particularly for water heaters which are also connected to a solar system, and more particularly to the visual indication of their positive performance and/or their temperature.
It is well known to provide a small incandescent lamp, usually a red one, connected to the circuit in such a manner that, by its glowing, it indicates that the device is under current, e.
g.
the thermostatic switch thereof, if any, is in closed position.
When the circuit is broken, either automatically by the thermostat, or manually by an exterior switch, it stops glowing, announcing the breaking of the circuit.
STATE OF ART The above arrangement, although in general use, has obvious drawbacks.
The lamp being out of order, which may happen quite frequently, there is no visual indication whether the circuit is closed or not
