PROBLEM TO BE SOLVED: To easily confirm the progress of pollution by blinking a pollution stage display means corresponding to the pollution stage to be shifted to and then switching to lighting when shifting to another pollution stage according to a judgment result by a judgment means. SOLUTION: When the degree of pollution by the judgment of a judgment means (a microcomputer 52) is 'a little bit of pollution', for example, a lamp 61 of 'AMBER' is lit up, at the same time, a lamp 60 of 'GREEN' is turned off, and a lamp 62 of 'RED' is blinked. More specifically, it is indicated that the degree of pollution in a room is being shifted from the 'a little bit of pollution' state to a 'pollution' one. Then, the lamp 62 is lit up, and at the same time the lamps 60 and 61 are turned off. More specifically, it is indicated that the degree of pollution in the room is the 'pollution' state. Three lamps 60-62 corresponding to the degree of pollution are provided in a pollution stage display means (pollution display part), and the lamps 60-62 are lit up, thus easily recognizing the state of the air pollution in the room visually. |
