The air-conditioning rotator 15 has a honeycomb-shaped ventilation hole through which drying air or air-conditioning air flows. The vent may have a shape other than the honeycomb shape as long as it has air permeability. The air-conditioning rotating body 15 is formed of a hygroscopic substance containing zeolite and silica gel. This hygroscopic substance has a function of absorbing / dehumidifying and absorbing / discharging heat.

The rotating body drive motor 16 has a belt pulley on a rotating shaft. The rotation of the rotating body drive motor 16 is transmitted to the rotating body 15 for air conditioning via the belt pulley and the belt 17 wrapped around the outer circumference of the rotating body 15 for air conditioning. The air-conditioning rotator 15 is rotated at a low speed of 0.5 (r / min). Since the air-conditioning rotator 15 is rotated at a low speed and is light in weight, the rotator driving motor 16 needs to be a small output motor.

The air conditioning duct 18 is provided with a dust collecting filter 28 on the upstream side of the air conditioning rotating body 15. The dust contained in the air-conditioning air flowing through the air-conditioning ventilation passage is changed to the air-conditioning rotating body
Since it is removed by the dust collecting filter 28 on the upstream side before adhering to the air-conditioning unit, the air-conditioning rotator 15 can be prevented from impairing not only the air permeability but also the functions of moisture absorption / dehumidification and heat absorption / discharge.

The dust collecting filter 28 is detachably provided so that it can be inserted and removed from the bottom surface of the outer frame 1.

The drain groove 14a extends to below the outer frame 1. The condensed water generated by the heat exchange double-sided fan 6 as a heat exchanger is drained from a drain port 14a. Drain 1
Since the heater 4a is located on the upstream side of the heater 5, the condensed water is drained before touching the heater 5, which is safe.

The air-conditioning rotating body 15 for dehumidifying or heating the air-conditioning air flowing in the air-conditioning duct 18 is rotatably provided so as to face both the circulation ventilation duct 14 and the air-conditioning duct 18 arranged adjacent to each other. Therefore, the configuration is simpler and more compact than that using the conventional cooling cycle device described above. The rotating body drive motor 16 for rotating the air-conditioning rotating body 15 is extremely light in comparison with the compressor drive motor of the cycle device, so that the weight of the clothes dryer can be reduced. The configuration of the ventilation path is different from the conventional one and does not require many shutters, so that it is simple and suitable for mass production.

When hanging and drying, the support tube 25a is pulled out of the storage case 26 so that the hanging tube 25b protrudes to the front side of the outer frame 1 and a dried product is hung. When there are many dried items, the extension tube 25c is pulled out and the hanging accessories 25 are spread and used. When the hanging tool 25 is not used, the extension tube 25c can be stored in the extension tube 25c and the support tube 25a can be stored in the storage case 26 so that it is not obstructive and easy to use. is there.

The drum pulley 12 is provided with a one-way clutch 11 as shown in FIG. Drum pulley 12
Is mounted on the rotating shaft of the motor 10 via the one-way clutch 11, so that one-way rotation (forward rotation) of the motor 10 is transmitted to the drum pulley 12, but rotation in the opposite direction (reverse rotation) is transmitted. Not done. For this reason, the motor 10
Is rotated forward, the rotating drum 4 rotates, but when rotating in reverse, the rotating drum 4 is stopped.

The operation section 22 has the following operation section and display section as shown in FIG. There are five drying courses: a standard course, a hanging and drying course, an indoor dehumidifying course, and an indoor heating course. The clothes dryer is operated by selecting from these courses. By pressing the corresponding selection button, the selected driving course is illuminated. The power is turned on and off by pressing a power switch. Humidity and room temperature can be arbitrarily set from a high value to a low value. Each set value is displayed by turning on the display lamp. The selection of the set value is performed by the humidity setting button 33b or the temperature setting button 31b.

The controller 21 includes a power supply circuit, a microcomputer, and a drive circuit as shown in FIG. An external power supply is connected to the power supply circuit. The motor 10, the heater 5, and the rotating body drive motor 15 are connected to the drive circuit. The microcomputer has a temperature sensor 30
A, a temperature sensor B, a humidity sensor A, and a humidity sensor B are connected. The operation unit 22 is also connected to the microcomputer.

Next, the operation will be described.

First, the drying operation using the standard course will be described.

Press the select button to select a standard course,
The clothes 20 to be dried are put in the rotating drum 4 and a driving instruction is given. The motor 10 and the heater 5 are controlled by the controller 21.
, And the motor 10 rotates. Along with this, the rotating drum 4 and the heat exchange double-sided fan 6 rotate, and FIG.
As shown in (1), the flow of the drying air indicated by the arrow X and the flow of the cooling air (air conditioning air) indicated by the arrow Y occur. The drying air is heated by the heater 5 of the heating means, deprives the clothes 20 in the rotating drum 4 of moisture, becomes hot and humid, and is sent to the heat exchange double-sided fan 6. As shown in FIG. 14, the drying fan side that carries high-temperature and high-humidity dry air is cooled by an air-conditioning fan that carries cooling air, so that moisture in the dry air is removed as condensed water. The dried air from the water portion is heated by the heater 5 and flows into the rotating drum 4 again to take moisture from the clothes 20. By repeating this, the clothes 20 of the laundry are dried.

The water condensed by the drying fan is blown off by the centrifugal force of the fan and flows down the circulation ventilation path. Further, it flows through the circulation ventilation duct 14 and is drained from the drain port 14a.

Since the humidity of the dry air decreases as the clothing 20 dries, the humidity sensor A32 of the fan casing 7, which is a part of the circulation ventilation path, detects the humidity to reduce the dryness of the clothing 20. You can know. When the detection value of the humidity sensor A32 indicates that the drying state has been reached, the controller 21 stops the energization of the heater 5.

Although the clothes 20 are dried as a result, the clothes 20 cannot be immediately taken out of the rotary drum 4 because they are hot. In order to cool the garment 20 quickly, the air-conditioning rotator 15 is turned immediately after the energization of the heater 5 is stopped. Since the drying air and the cooling air (air conditioning air) flow inside the air-conditioning rotator 15, the part cooled by the cooling air (air conditioning air) slowly rotates and moves to the circulation ventilation passage through which the drying air flows. This cools the drying air. Since the cooled drying air is sent to the rotating drum 4, the clothes 2
Since 0 is cooled quickly, the drying operation is shortened. After performing this cooling operation for a predetermined time, the motor 10 and the rotating body drive motor 15 are stopped, and the clothes drying operation of the standard course is completed.

Next, hanging drying will be described.

Select a hanging course. This hanging-drying operation is performed when drying with less damage, shrinkage, wrinkles, etc. of the cloth.

As shown in FIG. 2, the hanging tool 25 is pulled out to the front side of the outer frame 1. The extension tube 25c is also pulled out. Suspension pipe 25
Hanger 29 with clothing 20 hung on b or extension tube 25c
Hanging. The wind direction plate 19 is set upward, and the air-conditioning air discharged from the cooling air outlet (air-conditioning air outlet) 1a is directly blown onto the clothes 20 suspended on the hanger 29 to make it easier to dry.

After preparing in this way, a hanging course is selected and operated. The motor 10, the heater 5, and the rotating body drive motor 16 are energized by an instruction from the controller 21. On the hanging course, the motor 10 rotates in the reverse direction. The rotation of the motor 10 is controlled by the one-way clutch 11
Does not reach. The heat exchange double-sided fan 6 is rotated while the rotating drum 4 is stopped. Thereby, as shown in FIG. 2, a flow of the drying air indicated by the arrow X and the cooling air (air conditioning air) indicated by the arrow Y is generated.

The cooling air (air conditioning air) sucked into the air conditioning fan side of the heat exchange double-sided fan 6 contains moisture taken from the clothes 20, but as shown in FIG. When passing through the inside, the moisture is taken by the air-conditioning rotating body 15. The air-conditioning rotator 15 is made of a moisture-absorbing substance containing zeolite and silica gel, so that it can absorb moisture. Since the air-conditioning air discharged from the cooling air outlet (air-conditioning air outlet) 1a is dry air from which moisture has been removed, the drying of the clothing 20 proceeds.

The moisture absorbed by the air-conditioning rotating body 15 evaporates when the drying air heated by the heater 5 flows through the circulation ventilation passage and passes through the inside of the air-conditioning rotating body 15 and evaporates into drying air. It is taken. The air-conditioning rotator 15 that absorbs moisture in the air-conditioning ventilation passage and removes and regenerates the moisture when the position where the moisture is absorbed moves to the circulation ventilation passage rotates slowly, so that the absorption and regeneration of the moisture is sufficient. It is done well.

The drying air containing the water removed from the air-conditioning rotary body 15 passes through the stopped rotating drum 4 and is exhausted, and flows into the fan casing cover 7 from the dry air suction port. Since the drying air flowing into the fan casing cover 7 and flowing on the drying fan side of the heat exchange double-sided fan is cooled by the cooling fan that carries the cooling air as described above, the moisture in the dry air is condensed water. It is pulled out. Since the heated air from which the moisture has been removed is heated by the heater and supplied to the air-conditioning rotating body 15, the air-conditioning rotating body 15 is regenerated.

In the hanging drying, since the clothes 20 are not dried while being rolled in the rotating drum 4, the cloth is hardly damaged, shrunk, and wrinkled, and there is no restriction on the volume of the drying chamber as the rotating drum 4. In addition, by using the one-way clutch 11 and rotating the motor 10 in the reverse direction, hanging and drying can be performed while the rotary drum 4 is stopped, so that energy can be saved and noise can be reduced.

Next, the dehumidifying operation of the room shown in FIG. 3 will be described.

When the indoor dehumidifying course and the set humidity are selected, the motor 10 and the rotating body driving motor 16 are energized by the instruction of the controller 21, and the motor 10 rotates in the reverse direction. The rotary drum 4 is stopped by the one-way clutch 11. The heat exchange double-sided fan 6 rotates, and a flow of drying air indicated by an arrow X and a flow of air conditioning air indicated by an arrow Y are generated. Further, the air-conditioning rotating body 15 is slowly rotated at a low speed by the rotating body drive motor 16.

From the outside air inlet 3a to the fan casing 7
The cooling air (air-conditioning air) sucked in is blown by the cooling fan side of the heat exchange double-sided fan 6 and flows downstream through the air-conditioning ventilation path, and the humidity is detected by the humidity sensor B33 provided in the air-conditioning duct 18. You.

The detected humidity is compared with the set humidity by the controller 21. When it is determined that the humidity is high, the heater 5 is energized.

The high-humidity cooling air (air-conditioning air) flowing through the air-conditioning duct 18 removes moisture when passing through the inside of the air-conditioning rotating body 15. Since the cooling air (air conditioning air) having a low humidity is discharged from the cooling air outlet (air conditioning air outlet) 1a, the room can be dehumidified.

The moisture absorbed by the air-conditioning rotating body 15 evaporates when the drying air heated by the heater 5 flows through the circulation ventilation path and passes through the inside of the air-conditioning rotating body 15 to become the drying air. It is taken. As described above, the air-conditioning rotating body 15 is regenerated so as to remove moisture and absorb moisture again, so that the dehumidifying operation can be continued without lowering the dehumidifying ability.

The moisture absorbed in the drying air is removed as condensed water by the heat exchange double-sided fan 6 as described above, and is discharged from the drain port 14.

When this clothes dryer is used as a dehumidifier, the dehumidification capacity is about the same as that of a general household dehumidifier (5 to 15 liters / day). Can be lowered to the extent. With such a dehumidifying capability, for example, when a clothes dryer is installed in a dressing room or the like, the room can be dehumidified by the clothes dryer without using another dehumidifier in the rainy season. It is possible to suppress the occurrence of mildew in seasons where there is much. In addition, steam during bathing can be removed.

When the humidity is low, light dehumidification can be performed by turning off the heater 5 and using the heater.

In the dehumidifying operation, since the rotary drum 4 is kept stopped, the above-mentioned energy saving and energy saving can be expected.

Next, the heating operation of the room shown in FIG. 3 will be described.

When the indoor heating course and the set temperature are selected, the motor 10 and the rotating body drive motor 16 are energized by the instruction of the controller 21, and the motor 10 rotates in the reverse direction. The rotary drum 4 is stopped by the one-way clutch 11. The heat exchange double-sided fan 6 rotates, and a flow of drying air indicated by an arrow X and a flow of air conditioning air indicated by an arrow Y are generated. Further, the air-conditioning rotating body 15 is slowly rotated at a low speed by the rotating body drive motor 16.

From the outside air intake 3a to the fan casing 7
The cooling air (air conditioning air) sucked into the air is blown on the cooling fan side of the heat exchange double-sided fan 6 and flows downstream through the air conditioning ventilation passage, and the temperature is detected by the temperature sensor B31 provided in the air conditioning duct 18. You. Detected temperature is controller 2
In step 1, the temperature is compared with the set temperature, and when it is determined that the temperature is low, the heater 5 is energized.

The cooling air (air conditioning air) sucked from the outside air inlet 3 a is heated by the heat exchange double-sided fan 6. Further, the cooling air (air conditioning air) is heated by the air conditioning rotating body 15 and the cooling air outlet (air conditioning air outlet) 1a
, The room can be heated.

Since the cooling air (air conditioning air) is heated twice by the heat exchange double-sided fan 6 and the air conditioning rotating body 15, the heat of the heater 5 is effectively used for heating.

Since the capacity of the heater 5 is about 1 KW, the temperature of the cooling air (air conditioning air) can be raised to about 60 to 80 ° C. For example, when a clothes dryer is installed in a dressing room or the like, the clothes dryer can be a heater in the dressing room. Rotating drum 4 with undressed clothes
If you put it inside, you can wear warm clothing.

When the temperature is higher than the set temperature, the power supply to the heater 5 is stopped.

In the heating operation, since the rotary drum 4 is kept stopped, the above-described energy saving and noise reduction can be expected.

Next, a flow chart showing the flow of each course will be described.

First, the flow of the standard course will be described with reference to FIG.
