In order to secure the watertightness of the outer duct 22, the outer duct 22 is provided so as to wrap around the outer periphery of the heat exchange chamber 21 and the outer duct 22 forms a duct with the outer wall of the heat exchange chamber 21.

２０に流れ込む。The operation in the above-mentioned structure will be described. When washing, rinsing and dehydration are completed and the drying process is started, the drum 5 is driven to rotate at a low speed by the motor 7 to loosen the clothes in the drum 5. Further, the drying heater 12 and the blower fan 13 are energized, and hot air is blown into the drum 5 from the front surface of the drum 5 through the first duct 11 and the front surface of the water tank 2. At this time, the clothes in the rotating drum 5 mix with the hot air, deprive the clothes of moisture, and become hot air with high humidity, which flows into the heat exchanger 20 from the side surface of the water tank 2 through the second duct 14.

ータ１２で加熱され、ドラム５内に送り込まれる。At this time, the water supply valve 17 is opened, and the cooling water flows through the water supply pipe 16 and flows into the outer duct 22 of the heat exchanger 20. Then, the supplied water flows into the heat exchange chamber 21 through the holes 24 in the outer wall of the heat exchange chamber 21 like a shower. That is, since the humid air passes through the shower, the humid air is deprived of water and becomes dry air, and is sent to the blower fan 13. Then, it is again heated by the drying heater 12 and fed into the drum 5.

を通り、洗濯乾燥機本体１外に排出される。Since the cooling water flows in from the entire outer peripheral surface of the heat exchange chamber 21 as described above, it is possible to make efficient contact with the humid air, the dehumidifying performance is good, and the drying time of the clothes in the drum 5 can be shortened. . Further, the cooling water flowing into the heat exchange chamber 21 receives the water tank 2, the drain valve 9, and the drain hose 10.
And is discharged to the outside of the washer / dryer main body 1.

断面積より広くしている。As shown in the figure, in the heat exchanger 25, the cross-sectional area of the heat exchange chamber 26 is divided into the second duct (inflow side duct) 14 to the heat exchange chamber 26, the heat exchange chamber 26 and the blower fan 13. It is made wider than the cross-sectional area of the connected third duct (outflow side duct) 14a.

効果的に熱交換される。The high-temperature and high-humidity circulating air passes through the second duct 14 and the heat exchange chamber 26 by the blower fan, and then passes through the third duct 1.
It flows to 4a. On the other hand, the cooling water flows from the water supply valve to the outer duct 22 through the water supply hose 16, and the heat exchange chamber 26
The cooling water is discharged from the outer duct 22 in a shower shape. Since the circulating air passes through the shower of the cooling water, the moisture in the circulating air is removed. At this time, since the cross-sectional area of the heat exchange chamber 26 is wider than that of the second duct 14 and the third duct 14a, the flow velocity of the circulating air is 2
At 6, the time becomes slower, the time of contact with the cooling water becomes longer, and the heat exchange is performed more effectively.
【００３２】これにより循環空気中の水分を多く取り除

ト１４ａは、熱交換室２８の上面端部に接続している。As shown in the figure, the heat exchanger 27 is provided in the heat exchange chamber 28 in which the circulating air flows, and in the center of the upper surface of the heat exchange chamber 28, and the cooling water is made to flow into the flow path of the heat exchange chamber 28. The nozzle 29 is connected to a water supply hose 16 connected to a water supply valve (not shown). The heat exchange chamber 28 has a mortar-like shape with its upper portion spread, and the nozzle 29 has a part of the passage narrowed. The third duct 14a is connected to the upper end of the heat exchange chamber 28.

Since the flow of the circulating air in the drying process is the same as in the first embodiment, only the dehumidifying action of the heat exchanger 27 will be described.

がれる。The hot and humid circulating air flows to the second duct 14, the heat exchange chamber 28, and the third duct 14a by a blower fan. At this time, the cooling water flowing from the water supply valve through the water supply hose 16 to the nozzle 29 becomes particulate at the portion where the nozzle 29 is narrowed. Then, cooling water in the form of fine particles is poured from the nozzle 29 into the heat exchange chamber 28 from the upper part of the heat exchange chamber 28 in the direction opposite to the flow direction of the circulating air.

間で効果的に熱交換できる。As described above, since the nozzle 29 is partly throttled, the cooling water becomes particulate and the heat exchange chamber 28
Since the heat exchange chamber 28 has a mortar-like shape with a wide upper portion, the flow velocity of the circulating air is slowed in the heat exchange chamber 28 and is effective in the entire space of the heat exchange chamber 28. Can exchange heat.

る。Further, since the heat exchange chamber 28 is tapered like a mortar, it is difficult for the fine fibers in the circulating air to adhere to the wall surface, so that the fibers do not accumulate and flow down easily with the cooling water. The fibers contained in the cooling water are stored in the water tank 2.
Without being deposited on the bottom surface, it is directly discharged through the drain valve 9 and the drain hose 10 to the outside of the washer / dryer main body 1.
