Abstract

A drying device includes a drying section to dry a recording medium; a cooling section to cool the recording medium conveyed from the drying section; and a duct to expel air inside the drying section to outside the drying device. The duct includes a joint section where the air from the drying section meets air from the cooling section meet. The air from the drying section containing moisture and solvent medium is cooled in the duct.

First claim

What is claimed is:

1. A drying device comprising:
a drying section to dry a recording medium;
a cooling section to cool the recording medium conveyed from the drying section;
a duct to guide air inside the drying section and air inside the cooling section, to a port communicated with an outside of the drying device; and
a first inflow portion through which the air in the drying section flows into the duct; and
a second inflow portion through which the air in the cooling sections flows into the duct,
wherein, in the duct, the second inflow portion is disposed at a position closer to the port than the first inflow portion.

2. The drying device according to claim 1 , wherein the duct forms a serpentine path.

3. The drying device according to claim 2 , wherein the duct includes partition plates that form the serpentine path.

4. The drying device according to claim 3 , wherein the duct further comprises a collection section to collect a condensed liquid, and said collection section is disposed at a position lower, in a vertical direction inside the duct, than the partition plates included in the duct.

5. The drying device according to claim 2 , wherein the duct includes a tube that forms the serpentine path.

6. The drying device according to claim 5 , wherein the duct further comprises a collection portion to which condensed droplets collect in the duct, and said collection portion is disposed at a position lower, in a vertical direction inside the duct, than the tube.

7. The drying device according to claim 1 , further comprising a collection section disposed at a bottom of the duct to collect a condensed liquid.

8. The drying device according to claim 1 , wherein the duct is made of stainless steel.

9. An inkjet printer system comprising:
an inkjet printer to form an image on a recording medium; and
the drying device according to claim 1 to dry the recording medium.
