いる。[Prior Art] A drum-type washer/dryer has a structure in which the drum rotates around a horizontal axis, and since washing and drying can be done in the same drum, it combines the functions of washing, dehydrating, and drying. It has become a typical washer/dryer.

している。As shown in FIGS. 5 and 6, a conventional drum-type washer/dryer includes a water tank 2 suspended from an outer box 1 by a spring 4, and a water tank 2 that rotates around a horizontal axis 3a inside the water tank 2. It has a double structure with the drum 3 arranged. Aquarium 2 is
It is suspended by springs 4 to absorb vibrations during operation, and has the function of storing and discharging washing liquid and dehydrating liquid. The drum 3 has a large number of small holes 5 throughout its peripheral wall for water absorption during washing, drainage during dehydration, and passage of warm air during drying.

び循環パイプ８が設けられている。The drying heater 6 is installed inside the upper part of the water tank 2 along the outer periphery of the drum 3, and during the drying process, hot air is flowed from above to below the drum 3, passing through the outside of the water tank 2 again. A blower 7 and a circulation pipe 8 are provided to circulate the drum 3.

にして行われる。[0006] The washing process is carried out by placing the laundry items in the drum 3, dropping washing water containing dissolved detergent from above to be incorporated into the laundry items, and rotating the drum 3 at a low speed. The articles to be washed in the drum 3 are lifted to near the top of the drum 3 by the centrifugal force caused by the rotation of the drum 3 and a bump (not shown), and then fall due to their own weight (referred to as tumbling). This tumbling is repeated, and the laundry is washed by the impact force when it falls. Rinsing is done in the same way.

水する場合は排水用ポンプ１０を用いることもある。The dewatering process is carried out by rotating the drum 3 at high speed and pressing the laundry items against the inner surface of the peripheral wall of the drum 3 using its centrifugal force. At this time, the water is blown away from the small hole 5 of the drum 3, runs along the inner surface of the water tank 2, is guided to the lower part thereof, and is discharged to the outside of the machine via the drain valve 9. When draining water to a high position, a drainage pump 10 may be used.

分を凝縮されて、その水分は機外へ排出される。The drying process is carried out by rotating the drum 3 at a low speed while heating the air inside the water tank 2 by energizing the drying heater 6. The air in the water tank 2 heated to a high temperature by the drying heater 6 is agitated by the rotation of the drum 3, raising the temperature of the entire interior of the water tank 2 (including the laundry items) and evaporating the moisture contained in the laundry items. let This hot and humid air is transferred from a circulation pipe 8 connected to the bottom of the water tank 2 to a blower 7.
It is sucked into the water tank 2, and is again connected to the drying heater 6.
It circulates through a route where it is heated. The hot and humid air sucked from the bottom of the water tank 2 comes into direct contact with the cooling water stored in the lower part of the circulation pipe 8, is cooled and condensed, and the water is discharged outside the machine.

たまつてつまりやすいという傾向もある。[Problems to be Solved by the Invention] When drying laundry items in a conventional drum-type washer/dryer, drying air that is heated in the drum 3 and becomes hot and humid is cooled and dehumidified in the circulation pipe 8. However, due to insufficient contact with the cooling water, the temperature of the circulating air does not decrease and the drying temperature increases.
There were problems such as damaging the fabric and increasing the temperature of the entire device. In addition, lint and the like generated from the laundry are blown away by the air and discharged from the water tank 2, and captured by the cooling water in the circulation pipe 8. However, the circulation pipes are thin and tend to be easily clogged with lint.

There are many parts to be assembled into the aquarium 2, such as the need to be attached to the aquarium 2, which leaves problems with assembly workability.
