Abstract
PURPOSE: To lower the pump discharge pressure as well as to subdue the ignition noise at the ignition stage in a hot-water supply using an electromagnetic pump activated by the diode rectified a.c. half wave, by providing a condenser connected in parallel with a diode.
CONSTITUTION: At the both ends of a diode 3, a direct circuit is connected, which consists of a relay contact 5 and a condenser 6. When a switch 2 is closed, as the contact 5 is closed, the voltage impresses an electromagnetic pump 4 through two direct circuit series; the diode 3 series as well as the contact 5 (of a relay 18) - the condenser 6 series, to obtain a waveform, (b). After several seconds, a relay coil 18 becomes an excited state, which closes the contact 5 to obtain an impressed voltage having the half wave, (c). Since the electromagnetic pump 4 is impressed with the wave form, (b) at the initial ignition stage, the activity of the electromagnetic pump 4 is restrained, which lowers the pump discharge pressure and subdues the ignition noise at the igntion stage.
