<p>PURPOSE:To make the temperature control reliable at low cost by a method wherein an electric resistor is fixed to a diaphragm of a diaphragm type thermostat opening and closing a contact by the expansion and contraction corresponding to any temperature fluctuation. CONSTITUTION:A diaphragm 4 of a thermostat 1 opening and closing the electric contact of a blower is sealed up making use of the displacement of the diaphragm 4 subject to the fluctuation of the ambient temperature to fix and seal up a heating resistor 10 to said diaphragm 10 through the intermediary of a metal fitting 8. Consequently the heating resistor 10 can heat the diaphragm 10 so efficiently that the contact of the thermostat 1 may be turned ON immediately to secure the closing operation after specified time lapse if the contact of the thermostat is turned OFF even if the main body of the thermostat or the periphery thereof cools down.</p> |
