Abstract
A method is for heating a functional liquid of a droplet discharging device that has a storage which houses a container storing a functional liquid containing a functional material; a droplet discharge head discharging the functional liquid in a droplet; a cooling means included to the storage and cooling the functional liquid; and a supply tube supplying the functional liquid that is cooled in the storage to the droplet discharge head. The method includes: heating the functional liquid in the supply tube with waste heat that is generated correspondingly to cooling of the cooling means.

A method for heating a functional liquid of a droplet discharging device having:
- a storage that houses a container storing a functional liquid containing a functional material;
- a droplet discharge head discharging the functional liquid in a droplet;
- a cooling means included to the storage and cooling the functional liquid;
- and a supply tube supplying the functional liquid that is cooled in the storage to the droplet discharge head,
- the method comprising:
- heating the functional liquid in the supply tube with waste heat that is generated correspondingly to cooling of the cooling means.
A method for heating a functional liquid of a droplet discharging device,
- having:
- a storage that houses a container storing a functional liquid containing a functional material;
- a droplet discharge head discharging the functional liquid in a droplet;
- a cooling means included to the storage and cooling the functional liquid;
- and a supply tube supplying the functional liquid that is cooled in the storage to the droplet discharge head,
- the method comprising:
