Title: Liquid atomizing device
Inventor: ISHIHARA YUJI
IPC: F02B75/02
Filed: 1986-03-12
Abstract: PURPOSE:To change the amount of atomization steplessly by a method wherein a control circuit, which conducts an atomizing device while controlling a period which causes a given number of A.C. waveforms to lack when an A.C. electric source is supplied to the atomizing device, is provided in the atomizing device. CONSTITUTION:A control circuit 15, which consists of a two-way thyristor 2 and a trigger generating circuit 3, controlling the two-way thyristor 2, is provided in the title atomizing device while the two-way thyristor 2 is inserted into the conducting circuit of the atomizing device 12. The lack of an electric source is effected in synchronization with the pass of the zero point of the electric source by an electric source zero cross signal generating unit 5 and a period until the electric source is lacked again is changed to change the conducting condition of the liquid atomizing device 12. Therefore, when a given time of the lacking of the electric source is shown by (t1), a conducting time is shown by (t2), the amount of atomization during a time wherein there is no lack of the electric source is W and (t1+t2)=T, then ((t2)/TW). If (t1)=2(cycle) and (t2)=1(cycle), (t2/T)W=0.333W is derived; if (t1)=2(cycle) and (t2)=10(cycle), (t2/T)=0.833W is derived. Thus, the amount of atomization may be changed substantially steplessly by changing (t2). According to this method, capacity control may be effected without distorting an impressing voltage at all.
