Further, the exhaust temperature sensor 17 and the clock pulse generation circuit 26 are connected to the input terminal of the drying operation control device 230, as well as a course selection switch 27 for selecting each course of the drying operation and a start switch for starting the drying operation. 28 is connected to the electrode 18 through a contact frequency output circuit 29, lfj and a dryness detection circuit 30. A drive circuit 24 is connected to the output terminal of the drying operation control device 23, and a display 3161 and an alarm such as a buzzer 32 are also connected to the output terminal of the drive circuit 24.
and heater 16 are connected, and these motor 7 and heater 1
A power source 34 is connected to each power source end r of the power source terminal r of the power source 6 and the input terminal of the front first g flow circuit 17 via a power switch 33.

More specifically, the contact frequency output circuit 29 is composed of an operational amplifier 35 and resistors 36 to 40 as shown in FIG. Since it emits, it is obtained from the electrode 18 and output to the drying operation control device 23.

Further, the dryness detection circuit 30 also includes an operational amplifier 41, 42, resistors 43 to 48, a capacitor 49, diodes 50 to 52.1, and a transistor 53, as shown in FIG.
As will be described later, the electrode 18 emits a signal with a voltage level corresponding to the degree of wetness of the clothes it comes into contact with, and the signal is obtained from the electrode 18 and output to the drying operation control device 23. It looks like this.

On the other hand, the display 31 is composed of, for example, a set of three 7-segment light emitting diodes, and is mounted on a ζ panel 54 disposed on a part of the front surface of the front outer box 1, as shown in FIG. The course selection switches 27. are arranged side by side, and the course selection switches 27. Start switch 28 and T source switch 3

Now, in the case of the device configured as described above, in order to carry out the drying operation, first open the door 4 and put the clothes to be dried (not shown) into the drum 2 through the clothes entrance 3, and then close the drum 4. 33, then operate the course selection switch notch 27, and then operate the start switch 28. Then, the drying operation control device 23 starts operating, and first the motor 7 and the heater are controlled through the drive circuit 24.
6 is energized. Therefore, the heater 16 generates heat at the same time as the motor 7 starts, and the motor 7 simultaneously rotates the fan 6 via the belt transmission mechanism 8 and rotates the drum 2 via the belt transmission mechanism 9. Therefore, the clothes to be dried stored in the drum 2 are agitated and
i The clothes to be dried are moved to the electrode 18 by being stirred by the crosspiece.
come into contact with. Here, the frequency of contact of the clothes to be dried with the electrode 18 is proportional to the amount of ultra-drying load, such that it is high when the mouth of the clothes to be dried, that is, the drying negative 6:f l' is large, and low when it is small. From the electrode 18, the drying negative (;:f) is determined depending on the contactor.Then, the drying operation control device 23 is activated at the beginning of this drying operation.
The amount of drying load is determined based on the signal obtained from the two-legged electrode 18 through the contact frequency output circuit 29, and if it is less than the specified container -〇, the drying operation is started according to the drying capacity of the melon. Predict the time required to finish] 7. -r
The tpI result is given to the display 31 to cause the display 31 to display the predicted time in numbers as shown in FIG. still,
As an example, the number 17 rl 20J is displayed in FIG.
It is displayed that it will take 20 minutes.

On the other hand, based on the rotation of the fan 6, the air inside the drum 2 passes through the filter 12 and the exhaust air 1110 to the suction port 11.
It is sucked into the fan casing 5 from the outlet port 15, and is further discharged into the duct 14 from the discharge port 15.
Circulation through the drum 1 and back into the drum 2 from the air opening 13 is started. On the other hand, at the same time, the air outside the machine is sucked into the fan casing 5 from the fresh air intake port 20 and is discharged outside the machine from the fresh air outlet 21. Heat is exchanged between the air and the air outside the machine via the fan 6, and the air inside the drum 2 is dehumidified. Therefore, air that has been dehumidified and heated by the heater 16 flowing into the duct 14, that is, warm air, is sequentially supplied into the drum 2.
The clothes will be gradually dried. In addition, as the drying operation progresses, the table value in the above display: ', :: The required time is sequentially displayed. Then, the electrode 18 emits a signal with a voltage level corresponding to the degree of wetness of the clothes to be dried, which are kept in contact with each other.
As the drying of the clothes to be dried progresses, the voltage level gradually decreases and becomes lower than the basic value at the time of completion of drying. Therefore, the drying operation control device 23 has two electrodes 18.
The dampness of the clothes to be dried is determined based on the voltage height signal obtained from the dryness detection circuit 30, and the voltage height of the signal indicating the dampness is a standard value as described above. When it becomes lower than Jl, the power to the motor 7 and the heater 15 is cut off through the drive circuit 24, and at the same time, the buzzer 32 is energized. Therefore, when the rotation of the drum 2 and fan 6 is stopped here, Hi, - Evening 1G departure;

In this case, the drying operation control device 23 adjusts to the abnormally large drying load obtained from the electrode 18 through the contact output circuit 29 at the beginning of the drying operation. ↓ ÷ ζ (Next, it is judged that the dryness (α negative 6: f is greater than the specified value 14, and the buzzer 32 is sounded in a manner different from the above-mentioned end notification, for example, to indicate an abnormality. At the same time, the display 31 displays a message different from the normal display, such as rFULJ shown in FIG. 5, so that the user can know the abnormality. By correcting the operation, it is possible to prevent erroneous operation.Therefore, there is no need to worry about the situation where the clothes to be dried are not dried at the end of the drying operation, and, There is no need to wear out the support part of the drum 2, the motor 7, the belt transmission mechanisms 8, 9, etc., and the life of the drying machine can be extended. The time required for the drying operation is predicted on the display 31.
In the case where the drying operation end time is displayed as 1, it is possible to eliminate the difference from the actual drying operation end time and improve usability. Furthermore, in this case, as described in -1-, since both the abnormality notification is performed by B→J'32 and the display 31 displays a different expression from the normal display,
Misunderstanding or mishearing can be prevented as much as possible.
You can take more reliable measures.

In particular, the buzzer 32 often also serves as a termination notification as described above, and in such cases, the display 31 can also compensate for this.
1j. Mistakes can be prevented as much as possible.

In particular, in the case of the above-mentioned embodiment, the drying load is completely stopped in response to abnormalities such as the series of -1. ．． This makes it even more effective.

However, it is not always necessary to completely stop the drying operation, and therefore only the buzzer 32 (alarm) and indicator 31 are activated in response to an abnormality in the drying load as described above. It's okay. Further, the detection of the dry load amount and the degree of dryness may be performed by the exhaust temperature sensor 17 instead of the electrode 18. In addition, the display 31 is not limited to displaying the estimated time required for the drying operation and the remaining time based on the predicted time required for the drying operation, but may also display the time of a timer for executing the drying operation, for example. P for good or start of drying operation
It may also be something that displays the time of a timer for making a reservation. Furthermore, the indication that the dry load is abnormal due to i: 3 l is not limited to the above-mentioned rFULJ, but can be any other type of indication, such as an indication in other forms, or in other words, as long as it is an expression that is different from the normal indication. It may be.

In addition, the present invention is not limited to the embodiments shown in the drawings, and may be practiced with appropriate modifications within the scope of the invention.

[Effects of the Invention] As is clear from the above description, according to the dryer of the present invention, when the drying load amount is δ−,
Dry it? IJ jijl, it was determined that the abnormality was notified, and the display was displayed in a different expression from the normal display. This allows you to know more reliably, thereby preventing incorrect operation as much as possible, and eliminating the problem of undried clothes at the end of the drying operation. In addition to eliminating the need for the drum support part, motor, and bell!・
