Heating apparatus, medium processing apparatus, and medium processing method
A recording apparatus includes a support surface configured to support the medium and positioned downstream than the recording unit in a transporting direction in which a medium to which a liquid impinged by the recording unit is transported, a heating unit configured to heat the medium supported by the support surface, a flow channel including an inlet and an outlet opening toward the support surface, and a blower disposed in the flow channel and configured to allow a gas entering via the inlet to be blown out from the outlet. The inlet opens to allow at least some of the gas blown from the outlet to enter. The outlet is nearer to the recording unit than the inlet is, and its blowing direction goes toward at least an inlet side in a direction along the support surface.
1. A medium processing apparatus comprising:

an inner wall;
an outer wall;
a heating unit configured to heat the medium supported by the support surface;
a flow channel including an inlet and an outlet, the inlet and the outlet opening toward the support surface; and
a blower disposed in the flow channel and configured to allow a gas entering via the inlet to be blown out from the outlet, wherein
the inner wall houses the heating unit,
the outer wall houses the inner wall and the blower,
the flow channel is defined by an outer surface of the inner wall and an inner surface of the outer wall,
the inlet opens to allow at least some of the gas blown out from the outlet to enter the flow channel and circulate along the outer surface of the inner wall and the inner surface of the outer wall toward the blower,
the outlet is nearer to the recording unit than the inlet is, and
a blowing direction of the outlet goes toward at least an inlet side on which the inlet is located in a direction along the support surface.
2. The medium processing apparatus according to claim 1 , wherein
the inlet opens toward an outlet side on which the outlet is located.
3. The medium processing apparatus according to claim 1 , wherein
the inlet is provided with a guide face that inclines relative to the support surface and that extends toward an outlet side on which the outlet is located.
4. The medium processing apparatus according to claim 1 , wherein
the gas blown out from the outlet passes through a region heated by the heating unit.
5. The medium processing apparatus according to claim 4 , wherein
the heating unit is disposed at a position opposite to the support surface.
6. The medium processing apparatus according to claim 4 , wherein
the heating unit is disposed in the flow channel.
7. The medium processing apparatus according to claim 1 , wherein
an opening area of the outlet is smaller than an opening area of the inlet.
8. The medium processing apparatus according to claim 1 , comprising:
a housing configured to accommodate the heating unit, wherein
the inlet includes:
a first wall member configuring a part of the housing;
a second wall member that is located on the outlet side than the first wall member and configuring a part of the housing; and
side wall members intersecting with the first wall member and the second wall member and configuring parts of the housing, the side wall members extending up to a position closer to the support surface than a position of the second wall member.
9. The medium processing apparatus according to claim 8 , wherein
a distance between the side wall members is longer than a length of the support surface in a width direction intersecting with the transporting direction.
10. The medium processing apparatus according to claim 1 , comprising:
a plurality of the blowers arranged in a width direction intersecting with the transporting direction.
11. A heating apparatus disposed to face a support surface, the support surface being configured to support the medium, and positioned downstream than the recording unit in a transporting direction in which a medium to which a liquid impinged by the recording unit is transported, the heating apparatus comprising:
an inner wall;
an outer wall;
a heating unit configured to heat the medium supported by the support surface;
a flow channel including an inlet and an outlet, the inlet and outlet opening toward the support surface; and
a blower disposed in the flow channel and configured to allow a gas entering via the inlet to be blown out from the outlet, wherein
the inner wall houses the heating unit,
the outer wall houses the inner wall and the blower,
the flow channel is defined by an outer surface of the inner wall and an inner surface of the outer wall,
the inlet opens to allow at least some of the gas blown out from the outlet to enter the flow channel and circulate along the outer surface of the inner wall and the inner surface of the outer wall toward the blower,
the outlet is nearer to the recording unit than the inlet is, and
a blowing direction of the outlet goes toward at least an inlet side on which the inlet is located in a direction along the support surface.
12. A medium processing method configured to dry, in a medium processing apparatus including a flow channel disposed away from an inclined surface, the medium supported by the inclined surface, the method comprising:
heating a gas by a heating unit;
blowing the heated gas, by a blower, to cause the heated gas to flow from a vertical upside to a vertical downside along the inclined surface;
causing the flowing gas to enter into the flow channel; and
causing the gas to circulate,
wherein the flow channel is defined by an outer surface of an inner wall and an inner surface of an outer wall, the inner wall houses the heating unit, and the outer wall houses the inner wall and the blower.
