CONTROL METHOD AND SYSTEM FOR DIRECT-CURRENT WATER PUMP, WATER PUMP ASSEMBLY AND STEAM COOKING APPLIANCE

摘要

Disclosed is a control method for a direct-current water pump, comprising: a first control step (102) of controlling an amplification circuit to be activated and initiating control of a timer inside a chip to work when receiving a water delivery instruction; a counting step (104) of counting the number of interrupt signals generated by the timer; and a second control step (106) of controlling the amplification circuit to be deactivated when the number of interrupt signals reaches a first predetermined value, controlling the amplification circuit to be activated when the number of interrupt signals reaches a second predetermined value, and re-performing the counting step (104) and the second control step (106) after clearing the counted number of interrupt signals until receiving an instruction for stopping delivering water. The control method is able to precisely control the water yield of a water pump, and reduce the space occupied by the product and lower product manufacturing costs while continuously delivering water.
