Abstract
PURPOSE: To obtain an air cleaner of high sensitivity, a small size, light weight and a low cost by providing an air cleanliness sensor and an air cleanliness meter operated by the change in corona discharge current to the air cleaner.
CONSTITUTION: If air is allowed to flow while corona discharge is being caused by applying high voltage, the discharge current across both electrodes changes with the change in the dust concn. in the air, and therefore the dust concn. is detected from the change in this current. Thereupon, an air cleanliness sensor 28 and an air cleanliness meter 48 are provided to the air cleaner. In this way, the contamination of the air is accurately and easily measured with the corona discharge type sensor of a small size and light weight, and the air cleaner is operated.
