  CONTROL DEVICE OF THE HEATING RESISTANCE OF A STORAGE STOVE,.



   The object of the present invention is a device for automatic control of the heating resistance of an accumulation stove, comprising several independent heating circuits. Its purpose is to provide a device that regulates.,., - as a function of the outside temperature, the maximum core temperature of an electric storage stove.



   '. Storage stoves, the heating resistance of which is subdivided into several sections which can be switched on and off independently of each other are known per se. The invention is characterized by as many

On the other hand, if at the start of the heating period, the outside temperature is -11 C, the contact of thermostat 16 is closed as well as the contacts of thermostats 15 and 14.

   As a result, all coils 8, 9, 10 are energized, all contacts 5, 6,7 close and all resistors 2, 3,4 heat up until thermostat 10 opens., because thermostats 9 and 8 are inoperative due to the short-circuiting effected by auxiliary contacts 18 and 19. However, if during the night the outside temperature rises and exceeds -10 c, thermostat 16 opens the contact), the contacts 7 and 19 drop out and the core temperature is regulated by thermostat 12.



   The device described therefore adapts automatically to the conditions imposed by the outside temperature.

ABSTRACT. Device for controlling the heating resistance of a storage stove, the heating resistance of which is subdivided into several sections and each of which can be switched on and off., Characterized by as many internal thermostats as there are resistance sections to com. command, by as many external thermostats as there are 7 resistance sections to be controlled and by a locking device actuated at the time of switching an external thermostat to put in action the internal thermostats of the sections whose the outside thermostats are set for outside temperatures higher than the temperature which caused the switching of the outside thermostat in question.
