Title: Automatic air humidifying apparatus
Inventor: KOVACS JOZSEF
IPC: F22B1/30
Filed: 1982-10-01
Abstract: Automatic air humidifying apparatus in which cleaning to remove scale and other solid contaminants is initiated at variable intervals whose duration is determined as a function both of the amount of water which has been evaporated and the amount of contaminants accumulated in the cylinder. The amount of evaporated water is determined by measuring the current consumed by the electrical heating elements (2) during the operating period by means of a current/voltage converter (12) connected to the supply current which controls a VCO the output of which is counted or "integrated" by a dividing chain (16). The amount of solid contaminant accumulated is measured by determining the rate at which a fixed volume of liquid, measured by upper and lower level sensors (13, 9) within the cylinder, is discharged from the vessel through a path the flow cross-section of which is restricted by the contaminants. <IMAGE>
