Description of the invention (5) The convex part of the plural function of the component 17. In FIG. 1, the convex strip 17 is shown on the end face of the water-cooled dehumidifying air duct 14, but actually, as shown in FIG. 2, it faces the circulation ventilation path according to the position of the wide side walls in front and back. Set it as usual. Because of this water-cooled dehumidifying air duct 14, the narrow space between the outer frame 1 and the outer frame 1 is provided along the back surface of the outer groove 3. Therefore, the cross-sectional shape of the ventilation path is made into a thin shape with a wide depth and a narrow width. Specifically, the depth dimension of the water-cooled dehumidifying air duct 14 is about 3 mm, the width dimension is about 13 mm, and the length dimension is about 500 mm. Therefore, in order to increase the contact area between the cooling water and the circulating air 12, the cooling water is caused to flow down along the wall surface before and after the width (area) is widened. In addition, in order to reduce the increase in ventilation resistance, the plurality of convex strips 17 are arranged in a staggered shape extending in a horizontal direction on the wall surface of the water-cooled dehumidification air duct 16 in a horizontal direction at a height dimension of 3 mm, so that From the cooling water outflow port 16a of the cooling water supply pipe 16, cooling water 15 flowing out along the wall surface is guided along the wall surface, and the ribs 17 are staggered while being guided while passing through the wall surface.

593829 A7 B7 5. Description of the invention (6). (Please read the precautions on the back before filling this page.) In the dehydration process, the drain solenoid valve 8 is opened to discharge the laundry water in the outer tank 3, and the laundry tank 5 is rotated to perform centrifugal dehydration. And in the drying process, the washing tank 3 and / or the stirring blade 6 are rotated with the drain solenoid valve 8 opened, and the blower 18 is operated at the same time to extract the air in the outer tank 3 from the suction port 3 c and dehumidify it with water. After air-cooled dehumidification is applied to the air duct 14, the air is heated by a heater 19, and blown circulating air 12 is generated from the blowing nozzle 11 toward the laundry in the washing tub 5. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, which is located in the laundry tank 5 and is moistened by taking water from the laundry. The water-cooled dehumidification is performed by circulating the air 12 in the water-cooling dehumidifying air duct 14 and cooling it. The cooling water outflow 16 of the water supply pipe 16 and the cooling water 15 flowing out of the wall surface of the water-cooled dehumidifying air pipe 14 are guided along the wall surface and are guided in a horizontal direction by the convex strip 17 and are guided in a zigzag shape. , Widen the wall surface to make it flow down (make it flow down at a longer distance than the wall's slightly vertical distance), and then circulate the air 12 through the water-cooled dehumidifying air duct 1 4 It can be realized by contacting the cooling water flowing down the wall surface of the water-cooled dehumidifying air duct 14 with a wide area at the time of inside. The circulating air 12 rises at a high speed in the water-cooled dehumidifying air duct 14, so when the cooling water 15 overflows from the leading edge of the convex strip 17, it is blown by the circulating air 12 and becomes a water droplet and flies to On the downstream side, so the flow of cooling water 15 is so that it will not overflow. The corner formed by the inner wall surface of the water-cooled dehumidifying air duct 14 and the top of the convex strip 17 will not be applied along the convex paper scale.

Description of the invention (7) Article 17 The flow of the degree of overflow is ideal. The circulating air 12 rising in the water-cooled dehumidifying air duct 14 hits the leading edge of the ridge 17 and flows on the downstream (upper) side of the ridge 17 so that it can be in good contact. The cooling water 15 flowing through the corners formed on the upper surface of the ridge 17 and the wall surface can be cooled and dehumidified efficiently by heat exchange. According to this, the water-cooled dehumidifier 1 3 when the 'water-cooled dehumidifying air pipe 14 is' is guided in a zigzag shape along the inner wall surface and by the convex strip 17 in a horizontal direction, and the cooling water flowing down the wall surface 1 5 In a wide range, the circulating air 12 is brought into good contact with the heat exchange, and the dehumidifier can be cooled well. Moreover, the convex strip 17 provided on the inner wall surface of the water-cooled dehumidifying air duct 17 is a person having a low height (height), so the resistance to ventilation can also be reduced ', and the occurrence of water droplets flying on the downstream side can be prevented. Therefore, the size of the water-cooled dehumidifier 13 can be avoided.

This paper is again applicable to China National Standard (CNS) A4 specifications (210X297 mm) -19-593829 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _ B7 V. Description of the invention (17) The surface of the plate 2 5 A plurality of convex strips 17 extending in a vertical direction are arranged in a horizontal direction at intervals, and for each convex strip 17, a cooling water flow outlet 16 a of one of the cooling water supply pipes 16 is connected. A person who flows out of cooling water 15 (in a fan-like shape) in a puffy fashion, flows into each of the convex strips 17 and flows down. This embodiment also increases the contact area between the cooling water 15 and the circulating air 12 by increasing the number of the convex strips 17 to improve the heat exchange performance. As described above, the convex strip 17 of each embodiment can be changed to a concave strip constituting the same waterway. Also, the convex surface 17 or concave surface is provided on both sides of the heat exchange plate 25, and the contact surface between the cooling water 15 and the circulating air 12 can be made larger. The surface of the heat exchange plate 25 is provided with a fine concave or convex surface. As a result, the expansion of the dampness of the cooling water 15 can be increased, and the contact area with the circulating air 12 can be increased. In addition, the heat exchange plate 25 and the ridge 17 are made of a metal having excellent thermal conductivity without becoming a thermal impedance. However, if there is a problem of cost or rust, it can be changed to a material such as resin. In addition, the cooling water outflow port 16 a of the cooling water supply pipe 16 of each of the embodiments described above is ejected in such a way that the cooling water supply pipe 16 is directed downward from the cooling water supply pipe 16 toward the water-cooled dehumidifying air pipe 14 It can be ejected toward the inner wall side or toward the heat exchange plate 25 side, so that it can prevent the air from being sprayed up to the circulating air 12 and make the water droplets fly. This type of water-cooled dehumidifier (heat exchanger) can also be applied to clothes dryers or food dryers.

593829 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (18) (Effects of the invention) The present invention is due to the installation. The upper part of the wall facing the wind path is slightly vertical. The cooling water supply pipe flowing down along the wall surface, and the cooling water flowing down the cooling surface provided in the wall surface, and the area for expanding the cooling water flowing down area can expand the contact area between air and cooling water to increase heat exchange. (Cooling and dehumidifying) efficiency, at the same time can prevent the water droplets from flying on the downstream side. Furthermore, since the area under which the cooling water flows is enlarged, the water-cooled heat exchanger (water-cooled dehumidifier) can be made compact. Also, the components protruding from the ventilation path can be made as small as possible, and the ventilation resistance of the water-cooled heat exchanger (water-cooled dehumidifier) can be reduced. In addition, the water-cooled dehumidifier is integrated with the outer tank to form a space to eliminate waste, and the washing and drying mechanism can be made compact.
