性となる。The relationship between the temperature (i) of the first temperature sensor 5 and the temperature (b) of the second temperature sensor 6 when a small amount of clothes is put into the clothes dryer having the above configuration has the characteristics shown in FIG.
The temperature difference between these temperatures a and b becomes the characteristic of the temperature difference c in FIG. As is apparent from FIG. 7, when the temperature difference exceeds T1 within t1 hours after the start of operation, it is determined that the amount of cloth is small, and the operation is controlled to perform the set delay time t2. . In addition, when the amount of cloth is small, the temperature sensor 5, 6 when the operation is stopped halfway, the power is reset, a new large capacity of clothes is put in, and the operation is started,
B'and its temperature difference C'have the characteristics shown in FIGS. 8 and 9.

う問題点を有していた。Problems to be Solved by the Invention However, in the conventional configuration, when the temperature difference between the temperature sensors 5 and 6 reaches a predetermined value within a predetermined time t1, it is determined that the amount of cloth is small, and then only the operation for a certain time is continued. For example, if a large capacity is replaced during a small amount of operation, as shown in Fig. 9, the temperature difference exceeds T1 within t1 hours after the start of operation, so it is judged as a small amount, and it should be normal. Although it takes t4 hours for drying, there is a problem that the operation is performed for the delay time t2 and the operation ends at t3 time, which causes a malfunction.

少量を検知できる。When a small amount of clothes is put into the clothes dryer having the above configuration, operation is stopped midway, power is reset, and a large capacity of clothes is put in, the temperature d of the first temperature sensor 15 and the second temperature The temperature e of the sensor 16 has the characteristics shown in FIG. Also,
The characteristics shown in FIG. First, if you put in a small amount of clothes, the temperature difference will be within t1 hour.
Since T1 is exceeded, the microcomputer 17 detects a small amount and enters constant-time operation of t2 hours. At time t4 in the middle of this fixed-time operation, if the small amount of clothes previously put in is stopped drying, the power is reset, and a large amount of clothes is put in and restarted, the microcomputer 17 will detect the initial temperature difference. Since the temperature exceeds T1, the heater circuit is not energized until t5 hours, and the cold air operation is performed. After 5 hours, dry detection is started again.
At this point, since the temperature difference is T1 or less, the large capacity is no longer judged to be the small capacity. Also,
If the amount of clothes put in again is small, a small amount can be detected again.
