) A drum shaft fixed to the rear plate 2b of the drum 2 and supported by a rear bearing 23.

Further, a drum support member 24 related to the drum support part is fixed to the rear part of the drum 2 using the outer periphery of the rear surface of the outer frame 1,
An opening 25 is formed in the center of the drum support member 24 to discharge hot and humid air from the drum 2, and the drum support member 24 is attached to the rearmost part of the outer frame 1 toward a part of the corner of the outer frame 1. Is the outer frame 1 and the heat resistant chestnut 5 constructed to maintain an airtight structure? An exhaust duct 30 that connects to the opening 25 of the drum support member 24 and forms an exhaust passage 27 is disposed between the back cover 26 made of a plate, and the back cover 26 connects the exhaust duct 30 to a certain level. The exhaust tuft 3o is made of a material having at least a lower thermal conductivity than steel, such as a synthetic resin material or a waterproofed coagulated material. It is designed to be formed by

The exhaust duct 30 is connected to the opening 25 of the drum support member 24 to form the exhaust passage 27, and the back cover 26 covers the exhaust duct 30 with an insulating air layer having a certain thickness. This relates to the exhaust air passage section.

28Iri is a connecting pipe between the exhaust hole 24a of the drum support member 24 and the exhaust port 29.29 provided on the first corner side of the outer frame. Since the inside of the outer frame 1 is pressurized by the pressurizing fan 15, in order to prevent air leakage, the unused exhaust ports 29 and 29 are configured to maintain airtightness by using only a few lids 31.

Since the exhaust duct 30 is arranged by forming a Made of steel plate,
The exhaust duct 30 is made of a material with a lower thermal conductivity than steel, so even if the back cover 26 is cooled by outside air, the cold temperature will be transferred to the exhaust duct 3 due to the presence of the insulating air layer 32.
Even if it is not transmitted to 0, and even if it is transmitted to some extent, since the exhaust duct 30 is made of the above-mentioned material, there is little conduction to it, and in the end, the condensation on the inner wall of the exhaust duct 30 is reduced.
It can be made extremely small.

(2) Since the exhaust port 29 is formed at the bottom of the main body and the condensation water reservoir 33 is formed at the bottom of the exhaust duct 30, the moisture condensed on the inner wall of the durable exhaust duct 30 is removed by its own weight.
gather at Furthermore, since the direction of the exhaust air is approximately the same as the flow direction of the condensed fresh water, the exhaust air pressure moves the condensed water to the condensed water reservoir.
Easy to collect in 3. Therefore, the dew condensation water is reliably collected in the dew condensation water reservoir 33 and does not leak into the machine.

3) Since the dew condensation water reservoir 33 is provided close to the exhaust port 29 provided at the bottom of the exhaust air passage,
A drainage hose etc. can be connected to the condensation water reservoir 33,
Drainage can be easily carried out by using the exhaust port 29 as it is.

Of course, it is possible to provide the dew condensation water reservoir 33 at a position away from the exhaust port 29 and use it for drainage, or to form a separate drainage port, but in this case, the dew condensation water reservoir 33 When draining the condensed water collected in
A drainage hose (not shown) must be installed by making a hole in the body of the machine, for example, the back cover 26, and in this respect, the present embodiment is expected to have better effects.
