DEVICES FOR HEATING AND VENTILATING

摘要

PURPOSE: A heater and a ventilator are provided to certainly transmit and receive infrared signals between the heater and ventilator though an operator interrupts the transmission and the receiving. CONSTITUTION: A gas stove(22) contains a switch detection unit(40) to detect a start or a stop of heating; transmission LEDs(Light Emitting Diode)(44a,44b) to transmit infrared signals to start or to stop a ventilation fan(36) toward an oven hood(30); a timer(43) to measure time from the start or the stop of the heating; and a transmission control unit(42) to transmit the infrared signals when the switch detection unit detects the start or the stop of the heating and to transmit the infrared signals again when the timer measures the time. Thereby, the infrared signals are transmitted and received certainly.
