Description of the invention: [Technical field to which the invention belongs] [Technical Field] The present invention relates to a drum-type washer-dryer that sequentially performs washing, rinsing, dehydrating, and drying steps in a rotating drum. Prior Art 3 Background Art Conventionally, such a drum-type washer-dryer has a structure shown in FIG. This structure will be described below. As shown in FIG. N, the frame i supports the water tank 4 with 10 suspension members 2 and shock absorbers 3, and the opening of the water tank 4 is opened and closed by the door 5. A rotatable rotary drum 6 having a rotation axis in a substantially inclined direction is arranged in the water tank 4, and a plurality of water passing holes 7 and a baffle 8 are provided in the rotary drum 6. The casing 1 is provided with a water supply valve (water supply mechanism) 9 for washing and a water supply valve 10 for drying, and a drainage path 13 is connected to a drain 15 provided in the water tank 4 and a drainage port 11 and a drainage pump (drainage mechanism) 12. The blower 15 blows air into the water tank 4 through the blow-out port 14 and communicates with the heater 16 to the blower 15 and forms a series of dry-blinking circulation paths by connecting the heat exchanger 17 in the water tank 4 with the blower 15. The water supply pipe 18 is a pipe for passing water from the water supply valve 10 for drying into the heat exchanger 17. 20 The operation of the washing and drying steps will be described in the above structure. Once the laundry is put into the rotating drum 6 and the washing step is started, the washing water supply valve 9 is opened, and water is supplied to the water tank 4 to a predetermined water level. Next, the rotating roller 6 is driven at a rotation speed of about 50 r / min, and the inputted clothes are repeatedly raised and dropped by the broadcasting board 8 and washed by the impact force when the washing water is dropped to the water surface. net. 5 After the washing step 〆 is finished, the drain pump 12 is driven and the washing water is discharged through the drainage path 13. Once the drainage is completed, the rotating drum 6 is rotated at a high speed of about 1,000 r / min for dehydration. Then, once the dehydration step is completed, the process proceeds to a drying step. 10 15 20 The drying step is the same as the washing step. The rotating drum 6 is driven first, and the hot air heated by the fan 15 and the heater 16 is blown from the outlet 14 to the rotating drum while searching for the laundry in the rotating drum 6. 6 in order to heat and evaporate the moisture contained in the clothes. Next, high-temperature air containing steam was blown and exchanged, and mixed with the cooling water supplied to the heat-exchanger-shaped cooling water from the drying secret water valve 10, and heated for cold dehumidification. Then, the dehumidified air is tracked by the heater material and blown into the rotary drum 6 to dry the clothes. Thereby, a series of drying cycles are formed. In this conventional structure, when you want to form a series of drying cycles in the frame 1 with a limited size, you must marry the frame and the sink 4 _ 'So-come' will not make money area A large heat exchanger 17 suppresses dry energy. In addition, because this kind of heat exchanger uses the wind pressure of the wind of the wrong object to make the cooling water fly away from the ground in the heat exchange buckle: heat: in another way, if you want to improve the drying performance, you can easily increase the cycle: Bei J said that the problem was that the cross-sectional shape of the heat exchange office would break the balance of the cooling water, and the cooling water would be rolled up to -16, which significantly reduced the drying performance. Right dry_clothes with long hairs or pets' hairs, etc. Badger hairs can accumulate inside the heat exchanger 17 and cause failure.
