The lid 17 covers the clothes input port on the front of the dryer main body 11, and the motor 18 drives the rotary drum 12 and the blower fan 15.

The operation of the above configuration will be described. The lid 17 is opened, and the object to be dried (clothing) is put into the rotary drum 12 to start the operation. The drive of the motor 18 causes the blower fan 15 and the rotating drum 12 to rotate. The object to be dried (clothing) is agitated by the rotation of the rotary drum 12, and the drying air is blown by the rotation of the blower fan 15.
4 and supplied into the rotating drum 12. The drying air in the rotating drum 12 containing the moisture of the object to be dried (clothing) is sent from the exhaust path 16 by the blower fan 15 to the dryer body 1.
It is exhausted outside 1. The object to be dried (clothing) is thus dried.

Since the drying process is performed only by the stirring by the rotary drum 12 and the blowing by the blowing fan 15, the power consumption can be reduced, and the drying process with low running cost can be performed. The rotating drum 12
Since the temperature inside is equal to room temperature and does not become high,
Drying with little damage or shrinkage can be performed even on a material to be dried (clothing) having low durability against heat.

(Embodiment 2) As shown in FIG.
Numeral 9 is provided on the side of the main body 11 of the dryer on which the motor 18 is mounted, and the drying air is sucked through the air inlet 19. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described. In the drying process, when outside air is taken in from the intake port 19,
At the same time as cooling the motor 18, the drying air can be heated by the heat generated by the motor 18, and the rotating drum 12
The temperature of the drying air supplied into the inside can be higher than the outside air, and the relative humidity can be lower than the outside air, that is, the energy can be increased. Thereby, the time required for the drying process can be reduced.

(Embodiment 3) As shown in FIG. 3, a heater (heating means) 20 heats the drying air supplied into the rotary drum 12. The electrode 21 is disposed at a position where the electrode 21 comes into contact with the object to be dried (clothing) in the rotating drum 12 during operation. The electrode 21 is composed of a pair of conductive members and an insulating member between them (both not shown), and detects a resistance value between the conductive members.

Next, as shown in FIG. 4, the drying degree detecting means 22 detects the drying state of the object to be dried in the rotary drum 12 by the electrode 21 and inputs the output to the control means 23. The input setting means 24 is for input setting of a driving course and the like, and the display means 25 displays the set contents and the like. The storage unit 26 stores the motor 18 and the heater 20 via the driving unit 27 by the control unit 23.
The data necessary for controlling the operation of the device and performing the drying process is stored.

The control means 23 dries the material to be dried in the rotary drum 12 from the initial stage of the drying process only by stirring by the rotary drum 12 and blowing by the blower fan 15, and the drying degree detected by the drying degree detecting means 22. However, when a predetermined drying degree (for example, 85 to 90%) is reached, the drying air is heated by the heater 20 to perform the drying process. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described with reference to FIG. 5. When the operation is started at time t0, the material to be dried in the rotary drum 12 is dried only by stirring by the rotary drum 12 and blowing by the blowing fan 15. Therefore, the degree of drying of the object to be dried increases as time passes, as shown in the figure. When a predetermined degree of drying is detected by the drying degree detecting means 22 at time t1, the control means 23
The heater 20 is energized through the heater, and the drying air is heated by the heater 20 to perform the drying process.

As a result, the drying progress speed increases after the heater 20 is energized, and the drying time is shortened. In addition,
In FIG. 5, a dotted line indicates a change in the degree of drying when the heater 20 is not energized.

The degree of drying shown in FIG. 5 indicates the average degree of drying of the material to be dried in the rotary drum 12, and is generally reduced to about 103% in order to be touched and felt dry. Need to be done. For this reason, when the heater 20 is not energized, it takes a long time from when the degree of drying approaches 100% to when it reaches 103%. For this reason, when a predetermined degree of drying is detected by the degree-of-drying detecting means 22, the heater 20 is energized and the heater 20 heats the drying air to perform the drying process, whereby the drying time is reduced and the power consumed is reduced. The amount differs depending on the timing of supplying power to the heater 25, and in some cases increases as compared with the first embodiment, but can be reduced as compared with the conventional clothes dryer.

In the above-described embodiment, the drying degree detecting means 22 detects the drying state of the material to be dried in the rotary drum 12 by the electrode 21, but the temperature sensors are provided on the intake side and the exhaust side of the rotary drum 12.

Further, humidity sensors may be provided on the intake side and the exhaust side of the rotating drum 12, and the detected humidity difference may be used. It may be detected, or may be detected by a combination of these methods.

(Embodiment 4) Control means 23 in FIG.
Is to dry the object to be dried in the rotary drum 12 only from the initial stage of the drying process by the stirring of the rotary drum 12 and the blowing of the blower fan 15, and the degree of drying of the object to be dried in the rotary drum 12 is less than 100%. When a predetermined degree of drying (for example, 93 to 98%) is reached, the drying air is heated by the heater 20 to perform the drying process.

That is, a predetermined drying degree (for example, 85 to 90%) is detected by the drying degree detecting means 22,
After that, when a predetermined time elapses and the degree of drying of the object to be dried in the rotary drum 12 reaches the predetermined degree of drying of less than 100%, the drying air is heated by the heater 20 to perform the drying process. I have. The predetermined time in this case is controlled in accordance with the time until the predetermined degree of drying is detected by the drying degree detecting means 22.
It changes according to the amount of the material to be dried. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described with reference to FIG. 6. When the operation is started at time t0, the material to be dried in the rotary drum 12 is dried only by stirring by the rotary drum 12 and blowing by the blowing fan 15. Therefore, the degree of drying of the object to be dried increases as time passes, as shown in the figure. When the predetermined drying degree is detected by the drying degree detecting means 22 at the time t1, the control means 23 passes a predetermined time corresponding to the time until the predetermined drying degree is detected by the drying degree detecting means 22, When the drying degree of the object to be dried reaches a predetermined drying degree of less than 100%, the heater 20 is energized via the driving means 27, and the drying air is heated by the heater 20 to perform the drying process.

As a result, the drying progress speed increases after the heater 20 is energized, and the drying time is shortened. In addition,
In FIG. 6, a dotted line indicates a change in the degree of drying when the heater 20 is not energized. As indicated by the dotted line, when the degree of drying reaches 100% before the degree of drying, the drying progress speed is reduced, and a large amount of time is required until the end of drying, and the power consumption increases. By drying the heater 25 when a predetermined value 100% before the drying degree is detected, the object to be dried can be dried in a short time.
As a result, the power consumption is minimized, and the time required for the drying process is reduced.

(Embodiment 5) As shown in FIGS. 7 and 8, the temperature detecting means 28 detects the temperature of the exhaust gas from the rotating drum 12 and inputs its output to the control means 29.
The control unit 29 performs a drying process on the object to be dried in the rotary drum 12 with the drying air heated by the heater 20 from an initial stage of the drying process, and the rate of change of the exhaust gas temperature detected by the temperature detection unit 28 is a predetermined value. At this point, the heater 20 is turned off to agitate the rotating drum 12 and blow the fan 1.
The drying process is performed only by the air blow of No. 5. Other configurations are the same as those of the third embodiment.

The above configuration will be described with reference to FIGS. 9 and 10. When the heater 20 is energized from the initial stage of the drying process and the drying process is performed with the drying air heated by the heater 20, the exhaust gas temperature detected by the temperature detecting means 28 becomes the operation at time t0 as shown in FIG. From the start of operation, until the moisture contained in the object to be dried starts evaporating, the temperature rise is large, and when it evaporates from the object to be dried, the evaporation heat is taken away, so as shown by the dotted line , The temperature rise is small. When the rate of change of the exhaust gas temperature detected by the temperature detecting means 28 at time t3 becomes equal to or less than a predetermined value, the heater 20 is turned off and the operation is continued until drying is completed only by stirring the rotary drum 12 and blowing the blower fan 15.

The degree of drying of the object to be dried in the rotary drum 12 can be determined by turning on the heater 20 in the initial stage of the drying process, so that the temperature of the object to be dried (clothing) also increases, as shown by the solid line in FIG. The drying progress speed is faster than when the heater 20 shown by the dotted line is not energized. Even if the heater 20 is turned off, since the drying proceeds with the residual heat of the object to be dried, the drying progress speed does not immediately decrease. At time t4, as shown in FIG. 9, when the temperature of the material to be dried becomes equal to room temperature,
The drying proceeds at the same speed as indicated by the dotted line of 0, and the drying is completed.

As described above, since the heater 20 is energized to perform the drying process using hot air and the drying process using the residual heat of the object to be dried, the drying time is reduced. The reduction in power consumption depends on the timing at which the heater 20 is turned off, and in some cases increases as compared with the first embodiment, but can be reduced as compared with the conventional clothes dryer.

At this point, the heater 20 is turned off, the drying process is performed only by the stirring of the rotary drum 12 and the blowing of the blower fan 15, and the drying degree detected by the drying degree detecting means 22 is a predetermined drying degree (for example, 85 to 9).
(0%), the drying air is heated by the heater 20 to perform the drying process. Other configurations are the same as those of the fifth embodiment.

The operation of the above configuration will be described with reference to FIG. 11. As in the case of the fifth embodiment, the heater 20 is energized from the initial stage of the drying process, and is dried by the drying air heated by the heater 20. Then, when the rate of change of the exhaust gas temperature detected by the temperature detecting means 28 at time t3 becomes equal to or less than a predetermined value, the heater 20 is turned off, and the drying operation is performed only by the stirring of the rotary drum 12 and the blowing of the blowing fan 15.

Even if the heater 20 is turned off, the drying proceeds with the residual heat of the object to be dried, so that the drying speed does not immediately decrease. At time t5, the drying degree detecting means 22
When the degree of drying detected by the above becomes a predetermined degree of drying, the drying air is heated by the heater 20 to perform the drying process. As a result, the drying progress speed increases after the heater 20 is energized, and the drying time is shortened. Note that FIG.
The dotted line indicates the change in the degree of drying when the heater 20 is not energized.

(Embodiment 7) Control means 29 in FIG.
Is to dry the object to be dried in the rotating drum 12 with the drying air heated by the heater 20 from the initial stage of the drying process, and the rate of change of the exhaust gas temperature detected by the temperature detecting means 28 becomes equal to or less than a predetermined value. At this point, the heater 20 is turned off, the drying process is performed only by the stirring of the rotary drum 12 and the blowing of the blower fan 15, and the drying degree detected by the drying degree detecting means 22 is less than 100% (for example, 93%). The drying air is heated by the heater 20 at the point of time when the drying air reaches about 98%. Other configurations are the same as those of the fifth embodiment.

The operation of the above configuration will be described. In the initial stage of the drying process of the object to be dried in the rotary drum 12, the heater 20 is energized to supply heated drying air into the rotary drum 12 for drying. . Temperature detecting means 28
When the change rate of the exhaust gas temperature detected by the above becomes equal to or less than a predetermined value, the heater 20 is turned off, and the drying operation is performed only by the stirring of the rotary drum 12 and the blowing of the blowing fan 15.

Thereafter, after a predetermined drying degree is detected by the drying degree detecting means 22, a predetermined time has elapsed, and the drying degree of the object to be dried in the rotary drum 12 has become a predetermined drying degree of less than 100%. At this point, the heater 20 is energized and the heater 20 heats the drying air to perform the drying process.

Thus, the drying time is shortened.
The reduction in power consumption depends on the timing at which the heater 20 is turned off, and in some cases increases as compared with the first embodiment, but can be reduced as compared with the conventional clothes dryer.
