  • Publication number: 20090166348
    Abstract: A control method of an iron and its device, wherein the method comprises the steps of: (1) keeping the output temperature of the iron a temperature T1 suitable for ironing; (2) determining whether the iron is in a working state; if yes, step (1) is carried out; if no, step (3) is carried out; (3) determining whether the time of the iron's non-working state exceeds a predetermined time S1; if yes, step (4) is carried out; if no, step (1) is carried out; (4), the output temperature of the iron is kept at a temperature T2 that is lower than T1. The invention sets a control mode of reducing electricity consumption of the iron according to users' use habit. If only the iron isn't used for a relatively long time such as 5 minutes, the output temperature of the iron will be controlled to fall from a higher constant temperature, such as 200° C., to a lower constant temperature, such as 120° C.
