In this embodiment, as described above, the power control of the dehumidifying means 8 is performed in three steps. However, fine control of two or four or more steps does not cause any problem.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 3 is a sectional view showing the configuration of the present embodiment. In the present embodiment, the dehumidifying means 8 includes the adsorbing section 18 and the first
The blowing means 19, the second blowing means 20, and the heating means 21 are used.

FIG. 4 shows the dehumidifying means 8 used in this embodiment.
It is a perspective view which shows a structure of. The suction part 18 is provided in the intake pipe 12.
It absorbs moisture from the air in the drying cabinet 7 sucked in from above, and has a configuration shown in FIG. That is, the adsorbing section 18 is formed of an adsorbent 18a having a honeycomb structure in which silica gel, zeolite, or calcium chloride is formed into a disk shape or a column shape, and a large number of through holes are opened so that air flows in the axial direction. . The adsorbent 18a is rotated by the rotor motor 22 and the belt 23. Further, a partition plate 24 is provided on the surface of the adsorbent 18a.
And the partition plate 25 are arranged, and the partition plate 24 and the partition plate 25 slide on both surfaces of the adsorbent 18a. The adsorbent 18a is formed by the partition plate 24 and the partition plate 25.
Is separated into an adsorption zone 26 and a regeneration zone 27.

That is, while the adsorbent 18a is rotationally driven by the rotor motor 22 and the belt 23, the adsorbing section 18 takes in air from the suction pipe 12 connected to the exhaust hole 7a of the drying cabinet 7 by the first blowing means 19. The intake air is circulated from the blower tube 13 into the drying cabinet 7 through the adsorbent 18a. At this time, the intake air sucked from the intake pipe 12 comes into contact with the adsorption zone 26 of the adsorbent 18a, whereby moisture is adsorbed by the adsorbent 18a and dried. Further, the outside air blown by the second blowing means 20 is heated by the heating means 21 to contact the regeneration zone 27 of the adsorbent 18a, and the contacted outside air is exhausted again by the second blowing means 20 to the outside of the apparatus. I have.
In other words, in the regeneration zone 27, the hot air heated by the heating means 21 separates the moisture adsorbed by the adsorbent 18a, thereby regenerating the adsorbent 18a,
8a is restored. The moisture adsorbed in the adsorption zone 26 is separated by passing through the regeneration zone 27, and the adsorbent 18a is automatically regenerated. Further, the partition plate 24 and the partition plate 25 slide on the surface of the adsorbent 18a with the rotation of the adsorbent 18a, and partition so that there is no gap between the surfaces of the adsorption zone 26 and the regeneration zone 27. There is no air leakage between zones.

The operation of this embodiment will be described below. FIG. 5 is a flowchart showing a control program of the control means 11 of the present embodiment. In step 101, the start of the operation is confirmed, and in the subsequent step 102, timing of the operation time of the drying operation is started. At the same time, in step 103,
The first blowing means 19, the second blowing means 20, the heating means 21 and the rotor motor 22 which constitute the dehumidifying means 8 are turned on. That is, the air in the drying cabinet 7 is sucked, and the moisture is dehumidified by the adsorption unit 18. At this time, since the adsorbent 18a adsorbs moisture contained in the humid air in the drying cabinet 7, the heat of adsorption is generated by the condensation of water when the moisture is adsorbed. Therefore, the air that has passed through the adsorption section 18 is heated by the heat of adsorption and becomes high-temperature, low-humidity dry air. The dry air is blown from the blower tube 13 into the drying chamber 7 by the blower of the first blower 19. The air blown into the drying cabinet 7
The clothes are dried by coming into contact with the clothes in the drying cabinet 7. The low-humidity air including the moisture released from the clothes is sent to the dehumidifying means 8 again from the intake pipe 12 connected to the exhaust hole 7a.

In the following step 104, it is confirmed whether or not the duration of the drying operation has reached a predetermined time. If the result of this check is YES and the predetermined time has elapsed, the routine proceeds to step 105. In step 105, the heating means 21 constituting the dehumidifying means 8 is controlled to reduce the power consumption to a predetermined value. The power control for the heating means 21 may be performed by, for example, controlling the phase of a supply voltage from a commercial power supply. In the present embodiment, the power supply method is not particularly limited.

The reason why the power supplied to the heating means 21 is reduced to a predetermined value after the predetermined time has elapsed is the same as that described in the first embodiment. That is, the moisture contained in the clothes housed in the drying cabinet 7 decreases with the elapse of a predetermined time, and the amount of water released from the clothes from this stage is smaller than that in the initial stage of drying. Therefore, the amount of water to be adsorbed by the adsorbing section 18 is also reduced, and the electric power required to regenerate the adsorbent 18a is reduced. If the result of the check in step 104 is NO, the operation of each part in step 103 is continued.

Subsequently, in step 106, it is confirmed whether or not the second predetermined time described in the first embodiment has elapsed.
If the check result is YES, step 107
Then, the energizing power of the heating means 21 constituting the dehumidifying means 8 is reduced to the next predetermined value. Step 10
In step S8, it is checked whether the third predetermined time has elapsed in the drying operation. If the check result is YES, the process proceeds to step S109, in which the power supply to the heating means 21 constituting the dehumidifying means 8 is performed. To the next predetermined value. In this way, as a result of the check in the next step 110, when the total operation time reaches a predetermined value, step 1
In step 11, the first blowing means 19, the second blowing means 20, the heating means 21 and the rotor motor 22 are turned off, the drying is completed, and the apparatus stands by until the next operation starts. Step 10
6. While the result of the check in steps 108 and 110 is NO, the energized state in each step is maintained.

As described above, according to the present embodiment, the drying cabinet 7 for accommodating the clothes, the adsorbent 18a for absorbing moisture from the air in the drying cabinet 7, and the air in the drying cabinet 7 are suctioned. A first air blowing means 19 for discharging the air into the drying cabinet 7 again through the adsorbent 18a;
a second air blowing means 20 for exhausting air again out of the drying cabinet 7 through
A dehumidifying unit 8 comprising a heating unit 21 for heating the adsorbent 18a by raising the temperature of the air outside the drying cabinet 7 sucked by the second blowing unit 20, and between the drying cabinet 7 and the dehumidifying unit 8. Pipe 12 and blower pipe 13 for connecting the dehumidifier 8
And a control means 11 for controlling the heating power of the heating means 21 as the drying time elapses, thereby realizing a clothes dryer with high energy efficiency. It is.

In this embodiment, as described above, the power control of the dehumidifying means 8 is performed in three steps. However, fine control of two or four or more steps does not cause any problem.

(Embodiment 3) Next, a third embodiment of the present invention will be described. The configuration of the present embodiment is the same as that of the second embodiment, except that only the configuration of the control program of the control means 11 is different. FIG. 6 is a flowchart showing a control program of the control unit 11 of the present embodiment.

The operation of this embodiment will be described below. In step 201, the start of operation is confirmed, and in step 202,
The timing of the operation time of the drying operation is started. At the same time, in step 203, the first blowing means 19, the second blowing means 20, the heating means 21 and the rotor motor 22 which constitute the dehumidifying means 8 are turned on, the air in the drying cabinet 7 is sucked, and the dehumidifying unit 18 dehumidifies. . At this time, as described in the second embodiment, the adsorbent 18a generates heat of adsorption due to the condensation of the adsorbed moisture, and the air blown into the drying chamber 7 by the first blowing means 19 is high temperature and low humidity. It has become dry air. The dry air contacts the clothes in the drying cabinet 7 to dry the clothes. The low-temperature and high-humidity air containing moisture released from the clothes is sent to the dehumidifying means 8 again by the first blowing means 19.

Subsequently, in step 204, it is confirmed whether or not the drying operation has continued for a predetermined time. If the result of this check is YES, the operation proceeds to step 205, where the power consumption of the second blowing means 20 and the heating means 21 is reduced by a predetermined amount. In this state, the operation is continued, and when it is confirmed in step 206 that the operation time has reached the second predetermined time,
In step 207, the power consumption of the second blowing means 20 and the heating means 21 is further reduced by a predetermined amount. The reason for this is the first
In the same manner as described in the second embodiment or the second embodiment, when the drying proceeds after a predetermined time, the amount of moisture released from the clothes decreases, so that the dehumidifying amount that the dehumidifying means 8 dehumidifies is also small. Because In the present embodiment, the power consumption for the regeneration of the adsorbent 18a is reduced by reducing the power consumption of the second blowing means 20 and the heating means 21 by a predetermined amount.

Further, in steps 208 and 209, the reduction of the power consumption is repeated once. Subsequently, in step 210, when it is confirmed that the total operation time has reached a predetermined value, the process proceeds to step 211, where the first blowing means 19, the second blowing means 20, the heating means 21 and the rotor motor 22 are turned off, and drying is performed. Finish and wait until the next operation starts. Note that while the result of the check in step 106, step 108, or step 110 is NO, the energized state in each step is maintained.

As described above, according to the present embodiment, the drying cabinet 7 for accommodating the clothes, the adsorbent 18a for adsorbing moisture from the air in the drying cabinet 7, and the air in the drying cabinet 7 are sucked and sucked. A first blowing means 19 for discharging the air outside the drying chamber 7 again into the drying chamber 7 through the agent 18a;
Second air blowing means 20 for exhausting air again out of the drying cabinet 7 through the
A dehumidifying means 8 comprising a heating means 21 for heating the adsorbent 18a by heating the air outside the drying chamber 7 which the second air blowing means 20 has taken in, and between the drying chamber 7 and the dehumidifying means 8. The control unit 11 includes a suction pipe 12 and a blow pipe 13 to be connected, and a control means 11 for controlling the dehumidifying means 8. The control means 11 controls the amount of blowing air of the second blowing means 20 and the heating means as the drying time elapses. As a configuration in which the power supplied to the power supply 21 is gradually reduced, an energy-efficient clothes dryer is realized.

In this embodiment, as described above, the power control of the dehumidifying means 8 is performed in three steps. However, fine control in two or four or more steps does not cause any problem.

(Embodiment 4) Next, a fourth embodiment of the present invention will be described. The configuration of the present embodiment is the same as that of the second embodiment or the third embodiment, except that the control program of the control means 11 is different. FIG. 7 is a flowchart showing a control program of the control means 11 of the present embodiment.

8a. In addition, the adsorbent 18a generates heat of adsorption due to the condensation of the adsorbed moisture, and the air blown by the first blowing means 19 is high-temperature, low-humidity dry air. The dry air comes into contact with the clothes in the drying cabinet 7 to dry the clothes. The low-temperature and high-humidity air including the moisture released from the clothes is sent from the intake pipe 12 to the dehumidifying means 8 again,
It becomes dry air. Subsequently, in step 304, it is confirmed whether or not the drying operation has continued for a predetermined time. If the result of the check is YES, the process proceeds to step 305, in which the power supplied to the first blowing means 19, the second blowing means 20, and the heating means 21 constituting the dehumidifying means 8 is reduced to a predetermined value. The power control for the second blowing means 20 and the heating means 21 may be performed by, for example, controlling the phase of a supply voltage from a commercial power supply, and the present embodiment does not particularly limit the power supply method. .

And therefore
The amount of air blown by the first blowing means may be small, and the amount of regeneration air blown by the second blowing means 20 to regenerate the adsorbent 18a may be small. Further, when the amount of the regenerating air blown by the second blowing means 20 is controlled to be small, the amount of electricity to the heating means 21 for maintaining the temperature of the regenerating air at a predetermined temperature may be small. If the result of the check in step 304 is NO, the operation of each part in step 303 is continued.

Subsequently, at step 306, it is confirmed whether or not the drying operation has continued for a second predetermined time. If the result of the confirmation is YES, step 307
Then, the amount of electricity to the first blowing means 19, the second blowing means 20, and the heating means 21 constituting the dehumidifying means 8 is further reduced to the next predetermined value. In step 308, it is further confirmed whether or not the drying operation has elapsed for a third predetermined time. If the result of the check is YES, the process proceeds to step 309, and the amount of electricity to the first blowing means 19, the second blowing means 20, and the heating means 21 constituting the dehumidifying means 8 is further reduced to the next predetermined value. Let it.
