Title: Air cleaning hot air heating device
Inventor: NAGANO OSAMU
IPC: F24H3/04
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent deformation of a diaphragm by effecting a setting by which a proportional control valve is opened and gas is removed from a gas passage during an air cleaning operation to avoid a negative pressure condition, in the case where gas is discharged from the gas passage in a closed-valve condition and the negative pressure is imposed. SOLUTION: When an air cleaning operation switch 24 is pressed, a control device senses the action to rotate an air cleaning fan 23, followed by sucking unclean air to a grill 20, removing dust and smell by a filter 21 and diffusing the resultant cleaned air from a diffuser 22, thereby cleaning the air. Specifically, in a non-combusting mode, electric current is applied to an electromagnetic coil of a proportional control device 15 for a given period of time to allow an iron core to generate a magnetic field for moving valve rubber downward, followed by widening a gap with respect to a valve seat to remove gas closed in a gas passage. Thus, a setting for avoiding a negative pressure condition is effected and a diaphragm can be prevented from being deformed.
