Abstract

PROBLEM TO BE SOLVED: To shorten drying time, to make a machine body compact by reducing the number of part items, and to prevent vibration of an apparatus body from being transmitted to the dehumidifying duct side. SOLUTION: This fully automatic washer dryer dries clothes by blowing hot air in a drum 22 after washing the clothes in the inside drum 22. A double- tube type heat exchanger 40 is installed in the part. Water to be supplied in the drum 22 is passed through into an inner tube 41 of this double tube type heat exchanger 40. Hot water is passed through into an outer tube 42. Air is passed between fins 43 outside of the outer tube 42. Hot water warmed by exchanging heat with the hot water in the outer tube 42 while passing through into the inner tube 41 is supplied in the drum 22, and is used as washing and rinsing water. Hot air warmed by exchanging heat with the hot water in the outer tube 42 while passing between the fins 43 is blown in the drum 22 at clothes drying time. Highly humid exhaust air containing moisture evaporated from the clothes at this clothes drying time is exhausted outdoors via a discharge duct 33.

However, the prior art described above has the following disadvantages. 1. The drying time is long The amount of warm air blown into the inner drum 3 is an important factor that determines the drying time. Basically, the drying time becomes shorter as the amount of warm air increases. In the case of the conventional example, hot air that has received moisture from clothing is dehumidified with water or air to return to low-humidity air, and is again used for drying through the hot air electric heater 8. At this time, in order to dry the clothes efficiently, it is necessary to reduce the temperature of the hot air to a sufficiently low level in the dehumidifying process. To that end, the humidity of the hot air must be reduced as much as possible during the process. For example, when the heat exchange amount Q is constant, Q =
As shown by mc △ t (m: hot air volume, c: specific heat, Δt: temperature difference), the temperature difference can be increased by reducing the hot air volume m. That is, the air volume must be limited to some extent. Therefore, at present, there is a limit in shortening the drying time.

[0009] 2. In the case of warm water washing, it takes time to warm the washing water with the electric heater 5. In the case of the electric heater 5, the generated Joule heat increases as the current value increases. However, the contract for ordinary households is usually 30 A, and the upper limit of power consumption is about 1 kW.
Therefore, use 30 liters of water for washing and rinsing,
Consider a case where the temperature is raised to 0 ° C. (initial 20 ° C.). 1
The time required for a kW electric heater is given by Equation 1.

[Formula 1] Washing and rinsing are not started after the temperature reaches the set temperature, but if half of these are considered to contribute to prolonging the operation time, a total of about 20 minutes for washing and 10 minutes for rinsing compared to the case where hot water is not used is used. Will be extended. Therefore,
In the conventional example, the operation time is longer by 20 to 80 minutes depending on the amount of water than in the case where hot water is not used depending on the set temperature.
