Control circuit for an air cleaner |
摘要 |
A control circuit for an air cleaner including a gas sensor, an ultraviolet sensor and a control circuit for performing an automatic operation of the air cleaner in response to the detection of outputs of the sensors. A predetermined number of electrical pulses from the ultraviolet sensor are observed by the control circuit during a first predetermined time period after the passage of a second predetermined time period from a point of time when an initial pulse from the ultraviolet sensor has been inputted to the control circuit, the control circuit identifies the predetermined number of the pulses as a drive signal for initiating the operation of the air cleaner.
