Abstract
A heater assembly includes heating element for generating heat to warm a space to be heated. A heat sensor is provided sensing the temperature within the radiant heater assembly for automatically disabling the heater elements upon exposure of the sensor to temperature in excess of a predetermined threshold temperature. A tip-over switch is provided for disabling the heater elements in resonse to predetermined tilting movement of the radiant heater assembly relative to a normal upright position. Alert indicators are provided for indicating disablement of the heater elements upon actuation of either the heat sensor or tip-over switch.
Claims20
An alert system for monitoring the operation of a heater assembly, the heater assembly having heater means for generating heat to warm a space to be heated, thermostatic means for sensing the temperature of the space to be heated, and switch means responsive to the thermostatic means for controlling the operation of the heater means, the alert system comprising:
- a signaling means for emitting a humanly perceivable signal, signal switch means connected to the signaling means for enabling the signaling means to emit the signal, tilt sensing means for disabling the heater means in response to a predetermined tilting movement of the heater assembly relative to a normal upright position, and circuit means connecting the tilt sensing means and the signal switch means for causing the signal switch means to enable the signaling means upon disablement of the heater means by the tilt sensing means regardless of the temperature sensed by the thermostatic means.
A heater assembly comprising heat generating means for generating heat to warm a space to be heated, thermostatic means for sensing the temperature of the space to be heated, and switch means responsive to the thermostatic means for controlling the operation of the heater means, tilt means for sensing a predetermined tilting movement of the heater relative to a normal upright orientation, the tilt means including circuit means which operates in response to such tilting movement to disable the heat generating means, and alert means for indicating a tilting movement of the heater means sufficient to disable the heater means, the alert means being operable regardless of the temperature sensed by the thermostatic means.
An electric heater assembly operable in a normal upright orientation and susceptible to a tip-over condition comprising heater means for generating heat to warm a space to be heated, thermostat means for sensing the temperature in the space to be heated for controlling the heat generated by the heater means, overheat means coupled to the heater means for disabling the heater means upon sensing a temperature in the heater assembly in excess of a predetermined threshold temperature, tip-over means for disabling the heater means upon sensing a predetermined tilting movement of the heater assembly relative to the normal upright position, and alert means for indicating disablement of the heater means upon actuation of either the overheat means or the tip-over means, the alert means being operable regardless of the temperature sensed by the thermostat means.
An alert system for monitoring operation of an electric heater assembly, the heater assembly being operable in a normal upright orientation but susceptible to a tip-over condition, and having heater means for generating heat to warm a space to be heated, thermostatic means for sensing the temperature of the space to be heated, and switch means responsive to the thermostatic means for controlling the operation of the heater means, the alert system comprising first circuit means for automatically disabling the heater means upon elevation of the temperature within the heater assembly to a temperature in excess of a predetermined threshold temperature, second circuit means for automatically disabling the heater means in response to a predetermined tilting movement of the heater assembly relative to the normal upright position, and signaling means operable regardless of the temperature sensed by the thermostat means, for indicating the disablement of the heater means by one of the first and second circuit means.
