As shown in the figure, the heating and blowing means 1 sends hot air into a drying cabinet in which clothes to be dried are stored, and the cooling and blowing means 2 cools the hot air deprived of the clothes to be dried and includes the hot air. The condensed water is condensed and then sent to the heating and blowing means 1 again. The control means 3 also controls the heating and blowing means 1, the cooling and blowing means 2 and the like. The pre-cooling temperature detecting means 4 and the post-cooling temperature detecting means 5 detect the temperatures before and after the hot air is cooled, respectively. The temperature difference storage means 6 stores the temperature difference between the temperature detection means 4 and 5 every fixed time after the start of the drying operation. The first stroke detection means 7 detects that the amount of change of the temperature difference with respect to time has become equal to or less than a first predetermined value, and the second stroke detection means 8 performs detection of the first stroke. It is to detect that the amount of change of the temperature difference with respect to time has become equal to or greater than a second predetermined value. Then, when the time required for drying has elapsed when the second stroke is detected, the drying operation is terminated.

Problems to be Solved by the Invention In such a conventional clothes dryer, when the moisture content at the start of the drying operation of the clothes to be dried is small, (a) of FIG.
In some cases, the first stroke detecting means 7 does not detect the temperature difference from the beginning while the temperature difference shows a tendency to increase. Therefore, at this time, the temperature in the drying cabinet is too high, and the clothes to be dried are adversely affected by heat. In order to prevent this, as shown in FIG. 12, when the temperature of the pre-cooling temperature detecting means 4 rises to a predetermined value or more, the application of heat is stopped, and the air is blown into the drying chamber. When the temperature has dropped, the temperature inside the refrigerator is adjusted such as adding hot air again. For this reason, the temperature difference does not show the characteristic that can be obtained only by drying with normal hot air alone, as shown in FIG. Therefore, as described above, when the temperature of the pre-cooling temperature detecting means 4 has risen to a predetermined value or more, the drying operation has to be continued for a certain time from that point in time, and thereafter the drying operation has to be forcibly terminated.

Hot air 16 warmed by the heater 15 is added to the clothes 14 to be dried in the drying cabinet 13, and the hot air deprived of the clothes 14 to be dried is sent to the heater 15 again through the exhaust port 17. At this time, the hot air 16 containing water is cooled by the cooling fan 18 and a part of the water vapor is condensed. Therefore, the hot air 16 added to the clothes 14 to be dried through the heater 15 has a relatively low humidity, and the drying efficiency of the clothes 14 to be dried can be improved.

The operation of the above configuration will be described. At the same time as the drying operation is started, the drying chill 13 itself, the clothes 14 to be dried in the refrigerator, and the moisture contained in the clothes 14 to be dried are simultaneously heated by the hot air 16. However, the water has not been sufficiently heated, and has not been vaporized. Therefore, the temperature rise characteristics obtained by the pre-cooling temperature detecting means 4 include:
In addition to the specific heat of the drying cabinet 13 itself, the specific heat of the clothes 14 to be dried and the moisture has a great influence. That is, the specific heat of water (1c
al / g), the specific heat of the clothes 14 to be dried is also a general one.
Since it is close to 0.3 to 0.5 cal / g, the effect of the amount of the clothes 14 to be dried greatly affects the initial temperature rise as shown in FIG. Next, when the clothes 14 to be dried and the drying cabinet 13 are sufficiently warmed up, the moisture contained in the clothes 14 to be dried starts to evaporate.
The temperature inside the drying cabinet 13 rises above a certain level when drying humid clothing as shown in FIG. 4 (b) because the energy is much greater than the energy added to the temperature rise of the drying cabinet 13 itself. On the other hand, as shown in FIG. 4 (a), it is easy for the clothing having a low humidity to rise relatively easily with the lapse of time due to the small heat of vaporization. In addition, clothing 14 to be dried
It is experimentally known that the time required for the inside of the drying cabinet 13 to warm up in the initial stage of drying is generally about 10 minutes, depending on the amount of water and the external temperature. Detection means
The amount of the clothes 14 to be dried can be estimated from the temperature difference of 4,5. Further, the required drying time can be determined by judging the degree of wetness from the amount of change in the temperature difference thereafter. For example,
When the temperature difference is T 1 of the FIG. 5 (a), [Delta] T 1 by dehydration rate such as the change amount of the temperature difference FIG. 5 (b) (the moisture contained in the drying clothes 14), and [Delta] T 2 And the temperature difference is T 1
In the case the amount of change in the temperature difference is [Delta] T 1, the amount is small and dewatering rate of the drying clothes 14 can be determined to about 60%, when the amount of change in the temperature difference is [Delta] T 2 at temperature difference T 1 is the The amount of the dried clothes 14 is large and the dehydration rate can be determined to be 90%, and the drying time can be determined as t 1 and t 2 in FIG. 5 (c).

In addition, it is experimentally required that an appropriate judgment is made by using the change amount of the temperature difference of 10 to 20 minutes after the start of the operation for the detection time of the change amount of the temperature difference after 10 minutes at this time. However, as shown in FIGS. 6 (a) and 6 (b), when the temperature difference at 10 minutes is large and small, there is a slight temporal difference in the movement of the temperature difference depending on the magnitude of the humidity.
The smaller the temperature difference, the longer the time period is selected by the time zone selection means 12 to detect the inclination, whereby a more accurate drying time can be determined.

As described above, according to the clothes dryer of the embodiment of the present invention, the drying time determining means 10 performs drying based on the temperature difference between the pre-cooling temperature detecting means 4 and the post-cooling temperature detecting means 5 and the amount of change of this temperature difference with respect to time. Is determined, the time required for ideal drying can be determined even when the moisture content of the clothes 14 to be dried in the drying cabinet 13 at the start of the drying operation is small, and the drying operation is completed. can do.

Further, the change amount detecting means 9 changes the time zone for detecting the change amount based on the temperature difference stored in the temperature difference storage means 6, so that accurate drying even when the change amount of the temperature difference with respect to time is small.
