Abstract
A drying device includes multiple heaters and circuitry. The multiple heaters are driven by an alternating-current power supply to generate heat. The multiple heaters includes a first heater and a second heater other than the first heater. The circuitry repeatedly activates each of the multiple heaters in predetermined cycles corresponding to an AC cycle of the alternating-current power supply and shifts activation start timing between the first heater and the second heater by half the AC cycle of the alternating-current power supply.
Claims12
A drying device comprising:
- multiple heaters driven by an alternating-current power supply to generate heat, the multiple heaters including:
- a first heater;
- and
- a second heater other than the first heater;
- and
- circuitry configured to:
- repeatedly activate each of the multiple heaters in predetermined cycles corresponding to an AC cycle of the alternating-current power supply;
- and
- shift activation start timing between:
- the first heater;
- and
- the second heater,
- by half the AC cycle of the alternating-current power supply.
A heater control method comprising:
- repeatedly activating each of multiple heaters including a first heater and a second heater in predetermined cycles corresponding to an AC cycle of an alternating-current power supply;
- and
- shifting activation start timing between:
- the first heater;
- and
- the second heater,
- by half the AC cycle of the alternating-current power supply.
A non-transitory storage medium storing a plurality of instructions which, when executed by one or more processors, causes the one or more processors to perform a method, comprising:
- repeatedly activating each of multiple heaters including a first heater and a second heater in predetermined cycles corresponding to an AC cycle of an alternating-current power supply;
- and
- shifting activation start timing between:
- the first heater;
- and
- the second heater,
- by half the AC cycle of the alternating-current power supply.
