A second capacitor 9 is installed on the front side of the dehumidifying case 51. The second condenser 9 is also an orthogonal heat exchanger, with one side communicating with the regeneration duct 65 and the regeneration warm air duct 52, and the other side communicating with the second switching valve 8 and the intake duct 30.

A connection duct 62 is connected to the motor 43 side of the regeneration hot air duct 52 that is directly connected to the lower part of the dehumidification case 51 . Approximately the center of the connecting duct 62 is partitioned and divided into two chambers, with the - chamber connected to the regeneration hot air duct 52 and the other chamber connected to the regeneration hot air duct 53.

A regeneration fan 1 is mounted on a motor shaft 4B that can be driven by a motor 43.
0 is directly connected. The regeneration fan duct 63 surrounding the regeneration fan 10 communicates with the connection duct 62, and the connection duct 62 between the regeneration fan 1o and the regeneration hot air duct 53.
A regenerative heater 11 is housed inside.

The regeneration hot air 160 that has passed through the second condenser 9 is sucked in by the regeneration fan IO, heated by the regeneration heater 11 in the connection duct 62, and converted into regeneration hot air 170. The regenerated hot air 170 is sent from the regenerated hot air duct 53 to the -1 dehumidifier 6 or the second dehumidifier 7 selected by the second switching valve 8 .

Regarding the operation of the present invention based on the above agreement, FIGS.
The diagram is explained below.

When the motor 43 is operated, the drum 23, circulation fan 3, and regeneration fan 10 are rotated.

Due to the suction action of the circulation fan 3, the supply air 100 reaches Mc
1 condenser 4, the first switching valve 5, the first dehumidifier 6, the second condenser 9 and the heater 2, and the dry heat becomes 140
and is sucked into the drying chamber 1.

The drying hot air 140 that has dried the clothes, etc. in the drying chamber 1 contains steam emitted from the clothes, etc., and changes into wet air 150. A part of the heat of the wet air 150 is given to the supply air 100 by the Agl condenser 4, Ro KIIO can do it.

The warm air 110 is dehumidified and warmed by the first dehumidifier 6, and becomes dry@air 120. Dry temperature! ij1.120 recovers the regenerated energy by the regenerative heater 11 by the second condenser 9 and becomes dry hot air 130.

When the chemical moisture absorbent contained in the first dehumidifier 6 absorbs a certain amount of moisture, its moisture absorption performance decreases.
It is necessary to release the chemical moisture absorbent to the outside to regenerate it.

By interlockingly switching the first switching valve 5 and the second switching valve β at regular intervals using the timer 42, the state shown in FIG. 3 and the state shown in FIG.
The states in the diagram are repeated alternately.

The regeneration gas circulated by the regeneration fan 10 is supplied to the regeneration heater 1
1? This heats the air to become regenerated hot air 170, which passes through the second switching valve 8 and is supplied to the first dehumidifier 66.

The water absorbed in Figure 3 is the regenerated heat lK1 in Figure 4.
70 releases the water to the outside from the first dehumidifier 6, and restores the moisture absorption performance of the first dehumidifier 6.The regeneration heat 170 takes away the moisture released to the outside, and the relative humidity decreases to #yoboioo.
A moist hot air 180 close to * is obtained.

7Wd'4L 180t- When supplied to the second condenser 9, it is cooled to dry Si temperature 120, and the water is condensed to generate condensed i+d water 12. Since these condensation heats are recovered by the hot drying air 120, the drying temperature of the regeneration heater 11 is almost the same as the drying temperature sucked into the drying chamber 1;
Since the heat of the regenerative heater 11 is used for drying clothes, etc., a dryer with less energy loss can be obtained.

The second dehumidifier 7 in FIG. 4 has already been regenerated in FIG. 3 and has sufficient moisture absorption performance, so that the dry hot air 120 can be obtained.

The moisture absorption and regeneration cycle of the dehumidifier 6.7 explained above,
The dehumidifiers 6 and 7 are used in a fixed state.

As explained above, the regeneration fan 10 is attached to the motor shaft 48.
The regenerating fan duct 63 is integrated with the motor 43, and the drive system of the dryer is integrated.Dehumidifiers 6, 7, etc. are housed in the dehumidifying case 51 and are integrated. ing. The nine drive systems centered around the motor 43 and the dehumidifying function sections centered around the dehumidifiers 6 and 7 are independently separated, so assembly is easy.

Further, the drive system and the dehumidifying function section are installed on the same plane on the lower surface of the outer frame 20, and can be easily connected and assembled through the connection duct 62.

The condensed water 12 generated from the second condenser 9 is discharged to the outside through the drain provided in the regeneration hot air duct 52, but when the regeneration heater lit is installed in the regeneration hot air duct 52, the condensed water 12 is re-evaporated. As a result, heat loss occurs in the regeneration heater 11, resulting in energy savings and a reduction in ghee production. Therefore, in the present invention, the regeneration heater 11 is replaced by the regeneration fan 10.
The re-evaporation of the condensed water 12 is prevented by providing the condensed water 12 in the outlet connecting duct 62 and separating it from the regeneration hot air duct.

Furthermore, since the regeneration heater 11 is provided on the ventilation outlet side of the regeneration fan 10, the regeneration fan 10 and the motor shaft 4
8 is prevented from being directly heated.

When the dehumidifier 6.7, condenser 4.9, etc. themselves become high temperature, their performance deteriorates.
Note that the dehumidifier 6.7 and the condenser 4.9 are separated from the dehumidifying case 51, thereby preventing the dehumidifier 6.7 and the condenser 4.9 from being directly heated and causing performance deterioration.
