清浄機のアイオナイザ異常検出回路。 A voltage supply relay is connected between the high voltage generation circuit connected to the ionizer of the air purifier and the power supply of the circuit, and an abnormality detection circuit connected to the high voltage generation circuit and the voltage supply relay are connected. In between,
A pair of timers whose operating times are different from each other and to which abnormal signals detected by the abnormality detection circuit are input simultaneously, and the contacts of the voltage supply relay are cut off for the operating time of a short timer among these timers. a supply cutoff control circuit for controlling the
An abnormality counter that counts the number of times an abnormal signal is input to the short timer during the operation time of the long timer of the pair of timers; a reset circuit that resets the abnormality count counter when the count of the abnormality count reaches a predetermined number of times, and a signal that confirms the count and controls the supply cutoff control circuit when the count of the failure count counter reaches a predetermined number; Ionizer abnormality detection for an air purifier, which is connected to an operation confirmation circuit that emits a signal that activates an abnormality alarm such as an abnormality indicator lamp, and is composed of the above-mentioned abnormality counter and a frequency confirmation circuit that prevents input to the reset circuit. circuit.
