Abstract

PURPOSE:To prevent a place from being filled with smoke and to clean the air in an early stage by detecting the number of flames of lighters, matches, etc., by an ultraviolet ray detecting sensor and controlling the number of revolution of a motor driven blower according to the detected number of flames. CONSTITUTION:The signal sent from the ultraviolet ray detecting sensor 2 is so treated that the number of output of the sensor 2 in an unit time which is arbitrary set is calculated and the number of the detected pulses is integrated and the number of revolution of the motor driven blower is controlled according to the integrated value. Thus, the electric power for the motor driven blower is controlled by an electric power controlling circuit to be strong or weak according to whether the detected number of flames of match or lighter in the unit time is large or small. As a result, the air of room is cleaned in an early stage and the room is not filled with smoke.

Description of the Related Art Conventionally, as shown in Fig. 3, this type of air purifier is equipped with an ultraviolet detection sensor 2o that detects ultraviolet rays contained in the flame of a lighter or a matchstick, and is installed on the front of the main body. The electric blower was started. After starting, the rotational speed of the electric blower is changed according to the output of the gas center 21.

った。Problems to be Solved by the Invention In general, air purifiers remove air pollution caused by cigarette smoke. When starting at the UV detection center, the rotation speed of the electric blower was set to the standard rotation speed, and then the rotation speed of the electric blower was controlled according to the gas concentration detected by the gas center. However, the rate of air diffusion in the room is slow, and the gas sensor is located inside the main unit, so it takes time to detect it, and by the time the gas sensor detects it, the room is filled with cigarette smoke. Therefore, it was not possible to drive on ``strong'' mode until the room was filled with smoke to some extent.

電動送風機の電力の制御を行う。In the above configuration, the number of flames detected during unit time t is counted and taken as an integrated value, but if no flame is detected during unit time, the integrated value is subtracted. If this integrated value is large, it is "strong"
If the amount is less, the electric power of the electric blower is controlled via the electric power control circuit so that the electric blower is set to "weak".

、早期に部屋の空気の清浄を行うことが出来る。Here, a large number of flame detections is a factor in generating a large amount of smoke, so by increasing the output of the electric blower to "strong" as soon as a flame occurs, it is possible to prevent smoke from filling up and to prevent smoke from filling up quickly. It is possible to purify the air in the room.
