Note that the outer right cover 8 has four opening/closing cover pairs like the outer left cover 7, and has the same structure as the outer left cover 7, so a detailed description thereof will be omitted.

When the outer right cover 8 is in the closed state, the inner right wall 6 can be covered by the outer right cover 8, and an air layer for heat insulation can be generated between the inner right wall 6 and the outer right cover 8. A steam supply source (not shown) is installed in the space between the inner right wall 6 and the outer right cover 8 to send steam from the first heating roll 9A to the sixth heating roll 11B.

As shown in FIGS. 2 and 5, a top wall 43 is provided at the top of the housing 2, and a hood 44 is provided on the top wall 43. The hood 44 is located above the first heating roll 9A located most upstream among the first heating roll 9A to the sixth heating roll 11B, and bulges upward from the upper wall 43.

As shown in FIGS. 2 and 3, an exhaust duct 45 is provided in the hood 44 above the upper wall 43, and the exhaust duct 45 connects a suction duct section 46, a merging duct section 47, and an axial fan 48. have

The laundry input into the housing 2 from the input port 2a is pressed by the pressure roll 14 against the first heating roll 9A located on the most upstream side among the first heating roll 9A to the sixth heating roll 11B. Since the laundry sometimes contains the most moisture, the steam generated from the laundry heated by the first heating roll 9A is generated from the laundry heated by the second heating roll 9B to the sixth heating roll 11B. More than steam.

Moreover, the steam generated from the laundry decreases as it goes from the second heating roll 9B to the downstream heating rolls 10A, 10B, 11A, and 11B.

A second heating roll 9B and a fourth heating roll 10B are installed below the hood 44, and behind the hood 44 are a third heating roll 10A, a fifth heating roll 11A, and a sixth heating roll 10A. A roll 11B is installed.

As a result, the air containing moisture generated from the laundry heated by the first heating roll 9A to the sixth heating roll 11B is sucked into the suction duct portion 46 from the front suction port 46a and the rear suction port 46b. After that, they are merged in the merging duct 47, sucked into the axial fan 48, and discharged to the outside of the housing 2 through the opening 47a.

At this time, the air containing moisture generated from the first heating roll 9A rises directly above the first heating roll 9A and is efficiently sucked into the suction duct section 46 from the front suction port 46a and the rear suction port 46b. It will be done.

As shown in FIGS. 2 and 4, an air intake cover 49 is provided on the rear wall 4 of the housing 2, and an air intake port 49a is provided at the bottom of the air intake cover 49. The air intake port 49a is located behind (outside) the discharge port 2b and above the discharge port 2b.

Furthermore, since the air intake port 49a is located behind the exhaust port 2b and above the exhaust port 2b, it takes in high-temperature air discharged from the housing 2 through the exhaust port 2b. That is, the air intake port 49a is provided at a position where it can take in high-temperature air discharged from the housing 2 through the discharge port 2b.

Thereby, the air intake port 49a can simultaneously take in the outside air and the high-temperature air discharged from the exhaust port 2b into the intake duct 50, and the intake fan 51 can flow the high-temperature air into the interior of the casing 2. .

The intake fan 51 directs the air taken into the housing 2 from the heating roll pair 11 side located most downstream to the heating roll pair 9 side located most upstream. Air flows upward.

The outside air taken into the intake duct 50 from the air intake port 49a is mixed with the high-temperature air discharged from the exhaust port 2b, so the air flowing inside the housing 2 becomes high temperature, and the inside of the housing 2 is filled with outside air. can be prevented from being cooled by

Air taken into the casing 2 from the outside through the intake duct 50 by the intake fan 51 is directed to the hood 44 side above the third heating roll 10A, fifth heating roll 11A, and sixth heating roll 11B. flows to

It is discharged to the outside of the casing 2 from 47a.

Furthermore, when air is taken into the housing 2 from the outside through the intake duct 50 by the intake fan 51, air flows toward the hood 44 above the sixth heating roll 11B, the fifth heating roll 11A, and the third heating roll 10A. is generated.

Thereby, air can be prevented from stagnation inside the housing 2, and air can flow efficiently throughout the housing 2. Therefore, the air containing moisture generated from the laundry heated by the first heating roll 9A to the sixth heating roll 11B can be efficiently exhausted to the outside of the housing 2 from the exhaust duct 45.

In addition, since it is possible to suppress air stagnation inside the casing 2 due to the airflow flowing inside the casing 2, the stagnation of air inside the casing 2 can be suppressed. It is possible to prevent air that is colder than the air above from remaining, and while keeping the inside of the casing 2 at a high temperature, air containing moisture can be efficiently exhausted to the outside of the casing 2 from the exhaust duct 45.

For this reason, the temperature around the third heating roll 10A and the fifth heating roll 11A is suppressed from becoming lower than the temperature of the air above the housing 2, and the temperature around the third heating roll 10A and the fifth heating roll 11A is It becomes unnecessary to supply a large amount of steam to the heating roll 11A to heat the third heating roll 10A and the fifth heating roll 11A.

As a result, the consumption of steam supplied to the third heating roll 10A and the fifth heating roll 11A can be reduced, and as a result, the amount of steam supplied from the first heating roll 9A to the sixth heating roll 11B can be reduced. Consumption can be reduced.

Note that the intake duct 50 may take in air inside the housing 2 instead of taking in outside air. In this case, high-temperature air inside the housing 2 can be taken into the intake duct 50.
