Further, the fully automatic washer / dryer is provided with a water tank, a pipe, a switching valve and the like (not shown) as a washing machine, and various washing machines are used in the washing process and the drying process by the dryer. A control device (not shown) is provided to perform control. This control device performs the following control particularly in the drying process.

The outside air sucked through the outside air suction port 59a is heated by the heater 62 to become warm air (dry air) and the drum 53.
After entering the inside and drying the clothes, the clothes are exhausted. At this time, the control device detects the warm air based on the temperature detection signal of the inlet temperature sensor 66 or the outlet temperature sensor 67 that detects the temperature of the warm air. The temperature (inlet temperature or outlet temperature) is controlled to an appropriate temperature. That is, the inlet temperature sensor 66
Alternatively, an appropriate temperature designation value is given to the temperature detection value of the outlet temperature sensor 67, and the heater 62 is controlled so as to keep the temperature detection value at the temperature designation value.

Then, while controlling the temperature detection value of the inlet temperature sensor 66 or the outlet temperature sensor 67 to be the temperature designated value in this way, at the same time, the humidity of the warm air is based on the humidity detection signal of the outlet humidity sensor 68. The (outlet humidity) is controlled to an appropriate humidity. That is, an appropriate specified humidity value is given to the detected humidity value of the outlet humidity sensor 68, and when the detected humidity value falls below the specified humidity value, the temperature of the heater 62 is lowered thereafter, or in addition to this. Blower 61
The rotation speed is decreased, and further, water is sprayed from the spray nozzle 65 as necessary, so that the detected humidity value is controlled to be maintained at the specified humidity value.

Thereafter, the controller continues to dry the clothes for a while while keeping the humidity detection value of the outlet humidity sensor 68 at the specified humidity value as described above, and detects the load detection value of the load cell 70 (the load detection value of the plurality of load cells 70). The total value of) is monitored, and when the load detection value stabilizes at a constant value, it is determined that the clothes have been dried.

That is, since the load cells 70 provided on the respective support portions (suspension 69) of the processing tank 52 detect the loads supported by the respective support portions, the load detection values of these load cells 70 are controlled by the control device. If the total is added, the total weight of the tare of the processing tank 52 and the like and the weight of the clothes containing moisture in the drum 53 can be known. That is, the weight of the clothes that changes depending on the dry state can be detected together with the weight of the processing tank 52 that is constant regardless of the dry state of the clothes.

Since the humidity of the hot air (exit humidity) is maintained at the specified humidity based on the humidity detection signal of the exit humidity sensor 68, the load detection value (total value) of the load cell 70
If is stable at a certain value, it means that the clothes are uniformly in balance with the specified humidity. Therefore, as described above, when the load detection value (total value) of the load cell 70 stabilizes at a constant value, it can be determined that the drying is completed.

<Operation / Effect> The washing process and drying process of clothes performed in the fully automatic washer / dryer having the above configuration will be described.

(Washing process) In the washing process, the drum lid 55 is used.
After opening the container and putting the clothes in the drum 53, water is supplied to the drum 53 by using a pipe (not shown) under the control of the controller.
And is discharged from the inside of the drum 53, and the drum drive motor 57 rotates the drum 53 forward or backward at a low speed.
Preliminary cleaning, main cleaning with addition of detergent, and rinsing are performed. Then, after draining the water in the drum 53, the drum driving motor 57 rotates the drum 53 at a high speed to spin-dry it.
Thus, the washing process is completed and then the drying process is started.

(Drying Step) In the drying step, the clothes are dried under the control of the controller as follows. First, the rotation speed of the drum 53 is reduced to a low speed, and the blower 61 and the heater 62 are operated. The baffle 53b in the drum 53 contacts the peripheral wall of the drum 53 to lift the clothes upward, and then the tumbling operation of falling apart from the peripheral wall of the drum 53 above is repeated.

On the other hand, the blower 61 allows the outside air suction port 59a.
The outside air sucked from the air through the air filter 63 passes through the heater 62 in the middle of the treatment tank 5 as shown by an arrow in FIG.
2 into the drum 53 through the through hole 53a, passing through the clothes tumbling inside the drum 53, passing through the through hole 53a, and then into the exhaust duct 60 from the treatment tank 52, It is discharged to the outside of the machine through the air filter 64.

At this time, the air (outside air) sucked from the outside air intake port 59a is heated by the heater 62 to become warm air (dry air) and enters the drum 53 to dry the clothes. By controlling the heater 62 based on the detection signal of the inlet temperature sensor 66 or the outlet temperature sensor 67, the temperature is controlled to an appropriate temperature. In addition,
The control of the warm air temperature based on the temperature detection signal of the inlet temperature sensor 66 is used for clothing delicate with respect to the temperature, and the control of the warm air temperature based on the temperature detection signal of the outlet temperature sensor 67 is used for the clothing resistant to temperature. But the outlet temperature sensor 67
When controlling based on the temperature detection signal of
The number of times of ON-OFF of is increased, and the drying time is slightly extended.

After that, the drying end time is judged to finish the drying, and after the drying is finished, the heater 62 is stopped and the air of the outside air temperature is made to flow to perform the cool down (cooling).
Generally, the end time of drying is generally the difference between the temperature detection value of the inlet temperature sensor 66 and the temperature detection value of the outlet temperature sensor 67 (inlet / outlet temperature difference), the change in the temperature detection value of the outlet temperature sensor 67, or the outlet humidity sensor. It is determined based on the humidity detection value of 68. However, since all of these conventional methods for determining the drying end time determine the drying end time by a transient value of temperature or humidity, some clothes, especially when heterogeneous clothes are mixed, may be overloaded. Dryness is inevitable.

Therefore, in the washing clothes drying apparatus according to the first embodiment, the inlet temperature sensor 66 or the outlet temperature sensor 6 is used.
The temperature detection value of No. 7 is controlled so as to be maintained at the specified temperature value, and at the same time, the humidity of the hot air (outlet humidity) is controlled to be an appropriate humidity based on the humidity detection signal of the outlet humidity sensor 68. Then, the change in the load detection value (total value) of the load cell 70 is monitored, and when the load detection value stabilizes at a constant value, it is determined that the drying is completed. The specified humidity value is a relative humidity at a specified outlet temperature determined from the proper relative humidity of the clothes at room temperature, and is given to the control device. Alternatively, the absolute humidity may be used for control.

As described above, according to the washing clothes dryer of the first embodiment, the water is sprayed from the spray nozzle 71 as needed based on the humidity detection value of the outlet humidity sensor 67, so that the drum The warm air supplied to the inside of 53 is humidified to continue the drying of the clothes for a while while keeping the humidity detection value at the specified humidity value, and when the load detection value of the load cell 20 becomes stable at a constant value, the drying of the clothes is completed. Therefore, regardless of the amount, quality, shape, density of material, etc. of clothing,
Even when a plurality of kinds of clothes are mixed, all the clothes are evenly equal to the humidity (specified value) of the hot air supplied into the drum 53, so that there is no fear of overdrying and the entire clothes are kept at the desired humidity. It can be dried uniformly. Moreover, the configuration is a one-way system and simple.

[Second Embodiment] A washing clothes drying apparatus according to a second embodiment of the present invention will be described with reference to FIG.

An inlet humidity sensor 71 is provided on the downstream side of the spray nozzle in the duct 59. The inlet humidity sensor 71 detects the humidity of hot air flowing into the drum 53, and the load cell 70 is not provided. This is different from the washing clothes drying device 50 according to the first embodiment. In addition, the air supply duct 59 includes a blower 61, a heater 62, a spray nozzle 65, an inlet temperature sensor 66 and an inlet humidity sensor 71, and the exhaust duct 60 includes an outlet temperature sensor 67 and an outlet humidity sensor 68. The load cell 70 is not provided.

Then, a control device (not shown) performs the following control in the drying process. That is, the specified values are given to the temperature detection value of the inlet temperature sensor 66 and the humidity detection value of the inlet humidity sensor 71, and the inlet temperature sensor 6
By controlling the heater 62 based on the temperature detection value of 6, the temperature detection value is maintained at the specified temperature value, and the rotation of the blower 61 is controlled based on the humidity detection value of the inlet humidity sensor 71. , Spray nozzle 65 if necessary
The humidity detection value is maintained at the specified humidity value by controlling the spraying of water.

Thereafter, in the control device, the outlet temperature sensor 6
The temperature detection value of No. 7 or the humidity detection value of the outlet humidity sensor 68 is monitored, and when the temperature detection value or the humidity detection value stabilizes at a constant value, it is determined that the clothes have been dried.

That is, the temperature and humidity specified for the temperature detection value of the inlet temperature sensor 66 and the humidity detection value of the inlet humidity sensor 71 are set to the proper drying temperature determined by the type of clothes and to the proper relative humidity when cooled down. It is the appropriate relative humidity at the specified temperature that is determined so that the temperature detected value of the inlet temperature sensor 66 is maintained at the temperature specified value as described above, and at the same time, the humidity detected value of the inlet humidity sensor 71 is set to the specified humidity. By controlling so as to keep the clothes, the clothes are dried from the beginning with warm air having an appropriate humidity, and converge to the appropriate humidity with the passage of time. Then, at this time, the temperature detection value of the outlet temperature sensor 67 and the humidity detection value of the outlet humidity sensor 68 stabilize at a constant value (becomes the same as the designated value). Therefore, as described above, when the temperature detection value of the outlet temperature sensor 67 or the humidity detection value of the outlet humidity sensor 68 becomes stable at a constant value, it can be determined that the clothes have been dried. In addition, you may make it control by absolute humidity.

<Operation / Effect> As described above, according to the washing clothes drying apparatus of the second embodiment, water is sprayed from the spray nozzle 71 as needed based on the humidity detection value of the inlet humidity sensor 71. By doing so, the warm air supplied into the drum 53 is humidified to continue drying the clothes for a while while maintaining the humidity detection value at the specified humidity value.
When the temperature detection value of 7 or the humidity detection value of the outlet humidity sensor 68 stabilizes at a constant value, it is determined that the drying of the clothes is completed. Therefore, as in the case of the first embodiment, the amount of clothes,
Regardless of the quality, shape, density of material, etc., even when a plurality of types of clothes are mixed, since all the clothes are evenly equal to the humidity (specified value) of the hot air supplied into the drum 53,
There is no risk of overdrying, and the entire product can be dried uniformly at the desired humidity. Moreover, the configuration is a one-way system and simple.

In the first and second embodiments, an example of the drum type washing clothes drying device applied to the drum type fully automatic washer / dryer has been described, but the present invention is not limited to this, and the one-way type washing clothes drying device of the present invention is used. The apparatus can also be applied to so-called box dryers and tunnel finishers.
