The warm air is discharged through the second opening.
1. An ink heating device comprising:
an ink container that includes an ink pack filled with ink and a case housing the ink pack and having a first opening and a second opening; and
a blower that sends warm air into the case through one of the first opening and the second opening, wherein
the warm air is discharged through the other of the first opening and the second opening.
2. The ink heating device according to claim 1 , wherein
when a virtual line having the longest length among virtual lines from the first opening to respective portions of the inner surface of the case is defined as a longest virtual line,
when the case is divided into two parts of a first part and a second part on a virtual plane passing through a middle point of the longest virtual line and being orthogonal to the longest virtual line and when the first part is assumed to be where the first opening is disposed, the second opening is disposed in the second part.
3. The ink heating device according to claim 1 , wherein
the case is formed in a shape of a rectangular parallelepiped,
the first opening is provided on a first side surface among four side surfaces of the case,
the second opening is provided on a second side surface among the four side surfaces of the case, and
when the case is viewed from above, the second side surface has two end portions, and the second opening is provided at a position closer to the end portion having a longer distance to the first opening along an outer shape of the case than the end portion having a shorter distance to the first opening along the outer shape of the case.
4. The ink heating device according to claim 1 , comprising
a container mounting portion to which the ink container is attached, wherein
the container mounting portion includes a first duct connected to the blower,
the ink pack includes a spout that supplies the ink to outside at an end portion of the ink container on a far side in a mounting direction of the ink container to the container mounting portion,
the case includes a third opening for fixing the spout and the first opening on an end surface on a far side in the mounting direction, and
the first opening and the opening of the first duct face each other when the ink container is mounted on the container mounting portion.
5. The ink heating device according to claim 4 , wherein the first duct guides the warm air from the blower to the container mounting portion.
6. The ink heating device according to claim 4 , wherein the second opening is provided closer to a front side in the mounting direction of the case than the first opening.
7. The ink heating device according to claim 4 , wherein the container mounting portion includes a second duct connected to the blower,
the case is formed in a rectangular parallelepiped shape whose longitudinal direction is the mounting direction,
the second opening is provided at an end portion on the front side in the mounting direction of a side surface along the mounting direction of the case, and
in the container mounting portion, the second opening and an opening of the second duct face each other when the ink container is mounted on the container mounting portion.
8. The ink heating device according to claim 7 , wherein the first opening is provided at a position deviated to an opposite side of a side surface where the second opening is provided on an end surface of the case on a far side in the mounting direction.
9. The ink heating device according to claim 4 , comprising a plurality of sets of the ink containers and the container mounting portions, and
the first duct includes a branch pipe connected from the blower to the plurality of ink containers.
10. An inkjet recording apparatus comprising:
the ink heating device according to claim 1 ; and
an image forming unit forming an image by discharging the ink supplied from the ink heating device.
11. An ink supply apparatus comprising the ink heating device according to claim 1 , wherein the ink heated by the ink heating device is supplied.
12. An image forming system comprising:
the ink supply apparatus according to claim 11 ; and
an inkjet recording apparatus forming an image by discharging the ink supplied from the ink supply apparatus.
