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

1 - 7 . (canceled)

8 . A heating device comprising:
a heating section to heat a recording medium; a cooling section to cool the recording medium conveyed from the heating section; and a duct to guide air from inside the heating section to outside the heating device, the duct including:
a first inflow portion through which the air in the heating section flows into the duct; and
a second inflow portion through which the air in the cooling section flows into the duct,
wherein a width of the duct in a height direction of the heating device decreases from the first inflow portion toward the second inflow portion.

9 . The heating device according to claim 8 , further comprising an intake port to expel the air in the duct to outside the heating device,
wherein the width of the duct in the height direction of the heating device decreases from the first inflow portion toward the intake port.

10 . The heating device according to claim 8 , further comprising a collection unit disposed in the duct to collect a condensed liquid in the duct,
wherein the collection unit is disposed at a position at which the width of the duct in the height direction of the heating device is largest in the duct.

11 . The heating device according to claim 10 , further comprising:
an inclined portion disposed at a bottom of the duct and inclined downwardly toward the collection unit; and a serpentine path disposed above the inclined portion inside the duct.

12 . An inkjet printer system comprising:
an inkjet printer to form an image on a recording medium; and the heating device according to claim 8 to heat the recording medium.

13 . A heating-and-cooling device comprising:
a heating section to heat a recording medium; a cooling section to cool the recording medium conveyed from the heating section; and a duct to guide air inside the heating section to outside the heating-and-cooling device, the duct including:
a first inflow portion through which the air in the heating section flows into the duct; and
a second inflow portion through which the air in the cooling section flows into the duct,
wherein a width of the duct in a height direction of the heating-and-cooling device decreases from the first inflow portion toward the second inflow portion.

14 . The heating-and-cooling device according to claim 13 , further comprising
an intake port to expel the air in the duct to outside the heating-and-cooling device, wherein the width of the duct in the height direction of the heating-and-cooling device decreases from the first inflow portion toward the intake port.

15 . The heating-and-cooling device according to claim 13 , further comprising
a collection unit disposed in the duct to collect a condensed liquid in the duct, wherein the collection unit is disposed at a position at which the width of the duct in the height direction of the heating-and-cooling device is largest in the duct.

16 . The heating-and-cooling device according to claim 15 , further comprising:
an inclined portion disposed at a bottom of the duct and inclined downwardly toward the collection unit; and a serpentine path disposed above the inclined portion inside the duct.

17 . An inkjet printer system comprising:
an inkjet printer to form an image on a recording medium; and the heating-and-cooling device according to claim 13 to heat and cool the recording medium.

18 . A drying device comprising:
a heating section to heat a recording medium; a cooling section to cool the recording medium conveyed from the heating section; and a duct to guide air inside the heating section to outside the drying device, the duct including:
a first inflow portion through which the air in the heating section flows into the duct; and
a second inflow portion through which the air in the cooling section flows into the duct,
wherein a width of the duct in a height direction of the drying device decreases from the first inflow portion toward the second inflow portion.

19 . The drying device according to claim 18 , further comprising
an intake port to expel the air in the duct to outside the drying device, wherein the width of the duct in the height direction of the drying device decreases from the first inflow portion toward the intake port.

20 . The drying device according to claim 18 , further comprising
a collection unit disposed in the duct to collect a condensed liquid in the duct, wherein the collection unit is disposed at a position at which the width of the duct in the height direction of the drying device is largest in the duct.

21 . The drying device according to claim 20 , further comprising:
an inclined portion disposed at a bottom of the duct and inclined downwardly toward the collection unit; and a serpentine path disposed above the inclined portion inside the duct.

22 . An inkjet printer system comprising:
an inkjet printer to form an image on a recording medium; and the drying device according to claim 18 to dry the recording medium.
