Field of the Invention The present invention relates to a clothes dryer capable of stopping the operation in a drying time most suitable for the condition of the article to be dried (clothes) and displaying the required drying time at the beginning of the operation.

れている。2. Description of the Related Art In recent years, clothes dryers have become widespread, and the usage methods of users have been diversified.
There is a need to be able to optimally dry clothes with varying degrees of wetness. At the same time, from the viewpoint of usability, it is required that the time required for drying can be displayed to the user as early as possible, or the time until the end of drying can be displayed during driving.

ていた。Conventionally, this kind of clothes dryer is generally one in which the dryer itself judges the drying rate of clothes and stops the operation, and the time required for drying is estimated in the process.
In other words, by providing an electrode at one location inside the rotary drum and detecting the resistance value of the contact with clothes, when the contact of wet clothes is detected, the resistance value of the electrode is detected to be low. The dry state of the clothes is determined based on the change in the frequency at which a resistance value equal to or less than the value is detected in a certain period of time, and the time required for drying is displayed or the operation is stopped.

が高いためカーブＣのようになる。FIG. 8 shows a change in the frequency of the resistance value being a certain value or less with the progress of drying when typical clothes are dried by the dryer having such a structure. When the amount of cloth is large and the cloth is well moistened, the resistance value of the clothes contacting the electrodes is low and the frequency is high from the beginning, so that the curve A is obtained. Further, when the amount of cloth is large and the cloth is dry, the frequency of contact of the clothes with the electrodes is high, but since the clothes are dry from the beginning, the resistance value is high. Like On the other hand, when the amount of cloth is small but the cloth is well moistened, the frequency of contact of the clothes with the electrodes is low, but when the contact occurs, the resistance value is below a certain resistance value, and as a result, a curve B is obtained. Furthermore, when the amount of cloth is small and the cloth is dry, the frequency of contact of the clothes with the electrode is low and the resistance value is high, so that a curve C is obtained.

た。In such a conventional clothes dryer, it is not possible to distinguish between a case where the amount of cloth is large but dry, and a case where the amount of cloth is small but well moist. Since it is judged that the clothes are in the same condition and the drying operation is performed in the same sequence, there is a problem that if the amount of cloth is small but well wet, it will be undried, and if the amount of cloth is large, it will be over-dried Was. That is, there is a problem that the optimum drying time required for drying cannot be estimated in the initial stage of operation when the amount of clothes or the degree of wetness changes variously. In addition, there is a problem that the operation cannot be stopped in the optimum drying time depending on the condition of the clothes.

The conduction angle Φ of the phase control signal from 0 is large, the output of the pulse integration circuit 23 is large, and the absolute value of the average value A that is integrated and detected by the average voltage detector 24 is large. Further, the conduction angle Φ of the voltage applied to the motor 4 when the clothes are lifted by the lifter of the rotating drum 1 is such that the water content of each piece of clothes is large and the center of gravity is located on the outer peripheral side of the rotating drum 1. Therefore, the value becomes very large, and conversely, the conduction angle Φ when the clothes drop from the lifter becomes very small due to recoil. As a result, the amplitude B detected by the voltage amplitude detector 25 becomes a very large value, as shown in FIG. 4 (a).

Also,
The conduction angle Φ of the voltage applied to the motor 4 when the clothes are lifted by the lifter of the rotating drum 1 is small because the water content of each piece of clothes is small and the center of gravity is on the center side of the rotating drum 1. Therefore, the value becomes small, and the conduction angle Φ when the clothes fall from the lifter also becomes small. As a result, the amplitude B detected by the voltage amplitude detector 25 has a very small value, as shown in FIG. 4 (b).

The conduction angle Φ of the phase control signal from 20 becomes medium, and the absolute value of the average value Α detected by the integral conversion by the average voltage detector 24 becomes medium. Further, the conduction angle Φ of the voltage applied to the motor 4 when the clothes are lifted by the lifter of the rotating drum 1 has a large water content of each piece of clothes, and the center of gravity is located on the outer peripheral side of the rotating drum 1. Therefore, the value becomes large, and conversely, the conduction angle Φ when the clothes fall from the lifter becomes small due to recoil. As a result, the amplitude B detected by the voltage amplitude detector 25 has a large value, as shown in FIG. 4 (c).

Furthermore, the conduction angle Φ of the voltage applied to the motor 4 when the clothes are lifted by the lifter of the rotating drum 1 is also small because the water content of each piece of clothes is small and the center of gravity is located on the center side of the rotating drum 1. Therefore, the value becomes small, and the conduction angle Φ when the clothes fall from the lifter also becomes small. As a result, the amplitude B detected by the voltage amplitude detector 25 has a very small value, as shown in FIG. 4 (d).

The larger the absolute value, the larger the water content. Therefore, it is possible to estimate the state of clothes, the amount of clothes, and the water content from the output of the average voltage detection unit 24 and the output of the voltage amplitude detection unit 25 in the initial stage of operation.

Next, in step 33, the combination of the amount of clothes and the water content when the average value A is C is obtained from the intersections of the straight lines a, b and c in FIG. 5 (for example, points E, F and G). Next, step 34
Then, the intersections of the straight lines d, e, and f of the amplitude B in FIG. Finding (for example, points H, I, J) and finding a function g passing through this intersection (K). Next, in step 35, the water content when the amplitude B in the function g is D is obtained (for example,
L). In the next step 36, the amount of clothes is proportionally calculated by the above-mentioned function g and the basic equation of the intersection B and the amplitude B when the amplitude B is D, and the cloth amount and the water content are estimated. Step 37
Then, the required drying time is estimated in accordance with the preset amount of clothes and water content, a signal is sent to the display means 27, and the heater 7 is energized.
