Embodiments of the present invention will now be described with reference to the drawings. Embodiment 1 FIG. The air processing apparatus according to the first embodiment shown in FIGS. 1 to 5 utilizes a dehumidifying rotor 1 having a reversible moisture absorption / release function as shown in FIGS. As shown in FIGS. 3 and 4, a dehumidifying rotor 1 applied to this apparatus is formed by winding a corrugated structural material in which a hygroscopic agent such as silica gel is bonded to inorganic fibers such as ceramics by using a polymerization reaction to form a cylindrical shape. , A multi-layered passage 2 is formed concentrically. The tooth row 3 is formed on a part of the outer periphery of the dehumidification rotor 1, and the dehumidification rotor 1 rotatably supported by a shaft mounted at the center is provided on the rotation axis of the motor 4. The mounted reduction gear 5 is meshed and rotated in one direction by the motor 4. Each passage 2 of the dehumidifying rotor 1 has a linear shape parallel to the axis, and the open end faces both end surfaces of the dehumidifying rotor 1.

The dehumidifying rotor 1 having the above configuration is rotatably mounted on a mounting base plate 7 provided in a box-shaped main body casing 6, and is rotated at a low speed (from 0.5 rpm) by a motor 4.
About 1 rpm). In the main body casing 6, a part of the path is constituted by a passage 2 in a specific region 8 (hereinafter, referred to as a dehumidifying region) of the dehumidifying rotor 1, and both ends are formed as a suction port 9 and an air outlet 10. Is formed. The suction port 9 of the dehumidifying air passage 11 is opened at an upper front portion on the indoor side of the main body casing 6, and an air purification filter 12 for removing dust and odorous gas.
Is detachably mounted.

The outlet 10 of the dehumidifying air passage 11 is open at the front center of the main casing 6. A blower 13 that forms an airflow toward the dehumidification rotor 1 is mounted in a main body casing 6 that is located outside the suction port 9 of the dehumidification air passage 11 and outside the room. The dehumidifying air passage 11 has a suction port 9 as an inlet end, and a series of passages from a blower 13 through a passage 2 in a dehumidifying area 8 of the dehumidifying rotor 1 to a vent hole 10 formed as an outlet end from a ventilation hole formed in the mounting base plate 7. It is configured as a passage. In the air processing apparatus according to this embodiment, for example, since the air processing apparatus is configured to be inserted into a mouth frame of a ventilation opening 14 opened in a bathroom wall and attached thereto,
The main body casing 6 is formed in a hexahedron without irregularities on the outdoor side.

In the main casing 6, a part of the path on the inlet end side is formed by the passage 2 in a specific region 15 (hereinafter referred to as a purge region) in the preceding stage in the rotation direction of the passage 2 in the dehumidification region 8 in the dehumidification rotor 1. And a passage 2 of another specific area 17 (hereinafter referred to as a regeneration area) at a subsequent stage in the rotation direction of the purge area 15 of the dehumidifying rotor 1 again via a heating path provided with a heater 16 as a heating means. A regenerating air path 18 having an outlet end opening outside the room is formed. A suction port 19 which is an inlet end of the regeneration air passage 18 opens on a lower surface which is an outdoor side of the main casing 6, and an outlet 20 which is an outlet end of the regeneration air passage 18 is a rear surface which is an outdoor side of the main casing 6. It is open to. A blower 21 that forms an airflow from the suction port 19 to the air outlet 20 is attached to the regeneration air path 18 at the back of the suction port 19 of the regeneration air path 18. The blower 21 is driven by a common motor 22 with the blower 13 in the dehumidifying air passage 11. As a result, as shown in FIG. 4, the end face of the dehumidification rotor 1 facing the open end of the entire passage 2 is divided into three areas of a dehumidification area 8, a purge area 15, and a regeneration area 17. The dehumidifying area 8 occupies the widest angle of about 230 degrees on the entire end face, the purge area 15 has an angle of about 50 degrees, and the regeneration area 17 has an angle of about 80 degrees.

The heating path of the regeneration air path 18 is
Is constituted by a heating box 23 mounted on the mounting base plate 7 which slides in one end face in an airtight state. The heating box 23 connects the end of the passage 2 of the purge area 15 and the end of the passage 2 of the regeneration area 17 on one end side of the dehumidifying rotor 1 through an opening formed in the mounting base plate 7. In the heating box 23, a heater 16 for heating an air flow passing through the section is incorporated. Heating box 2
An exhaust box 24, which constitutes a part of a regeneration air passage 18, is attached to the regeneration area 17 on the other end surface side of the dehumidification rotor 1 facing the dehumidification rotor 3 so as to sandwich the dehumidification rotor 1.
The end face side of the dehumidification rotor 1 of the exhaust box 24 is open so that the end face of the dehumidification rotor 1 can slide in an airtight state. The exhaust box 24 communicates with the outlet 20 of the regeneration air passage 18.

As shown in FIGS. 1 and 2, the air processing apparatus having the above structure is inserted from the indoor side into a ventilation opening 14 or the like provided through a wall separating the indoor and outdoor, such as a bathroom, for regeneration. The air inlet 18 and the air outlet 20 of the air passage 18 are mounted so as to open to the outside (often outdoors). In order to make the room dry, the blowers 13 and 2
1 and the dehumidifying rotor 1 and the heater 16 are operated. By operating the blower 13, indoor air is introduced into the dehumidifying air passage 11 through the suction port 9.
From the air purification filter 12. The sucked air is supplied to the dehumidifying rotor 1 rotated by the blower 13.
Through the passage 2 of the dehumidifying area 8 from the outlet 10 again into the room. On the other hand, the operation of the blower 21 causes
8 is sent into the heating box 23 through the passage 2 in the purge area 15 of the rotating dehumidifying rotor 1, and the heater 16 in the heating box 23.
And the passage 2 in the regeneration area 17 of the dehumidifying rotor 1
Flows from the opposite direction, and is exhausted to the outside from the outlet 20 through the exhaust box 24 (see FIG. 5). Dehumidifying air passage 1
1 and the regeneration air path 18 are independent of each other over the entire path, so that the state quantity of the indoor air changes but little ventilation is performed.

The dehumidification rotor 1 is rotating at a low speed, and the passages 2 in the dehumidification area 8 are sequentially shifted to the regeneration area 17, and the passages 2 in the regeneration area 17 are sequentially purged 15
, And the passage 2 in the purge area 15 performs a continuous operation of shifting to the dehumidification area 8. A high-temperature airflow heated by the heater 16 flows into the passage 2 of the regeneration area 17 which constitutes a part of the regeneration air passage 18, and the dehumidification rotor 1 in the portion is dehumidified into the outside air continuously taken in. I have. The passage 2 of the dehumidifying rotor 1 that has been dehumidified by passing through the regeneration area 17 and provided with the dehumidifying ability is heated to a high temperature due to the heat of the heater 16, but is cooled by the outside air blown in the next purge area 15. Is done. The passage 2 of the dehumidification rotor 1 that has been cooled after passing through the purge region 15 sequentially moves to the dehumidification region 8 and continuously absorbs moisture from the airflow flowing through the dehumidification air passage 11 passing through the passage 2. The airflow which has become a dry atmosphere by being absorbed in moisture is blown out from the air outlet 10 into the room, and makes the room a dry atmosphere. The moisture of the dehumidifying rotor 1 that has absorbed moisture in the dehumidifying area 8 is released again in the regenerating area 17 to be regenerated, thereby providing dehumidifying ability.

In this air processing apparatus, the indoor air is not used for regeneration of the dehumidifying rotor 1, but is dehumidified and discharged outside using the outdoor air. A dry atmosphere is created by the indoor air circulating through the dehumidifying air passage 11. The air in the room is thus dehumidified continuously and continuously.
, It is processed into high-dry, clean air. Therefore, it is possible to make the room a dry atmosphere in a short time regardless of the humidity of the outside air, and the inside air is also cleaned. If the operation of the dehumidifying rotor 1 and the heater 16 is stopped and only the blowers 13 and 21 are operated, the device functions as an air cleaning device. The moisture absorption capacity of the dehumidification rotor 1 in the dehumidification region 8 is affected by the temperature. The lower the temperature, the higher the moisture absorption capacity. In this embodiment, the reproduction area 17
The dehumidification rotor 1 whose surface temperature has been increased by heating in the next step is cooled by the passage of outside air in the next purge area 15 and reaches the dehumidification area 8, so that the dehumidification capacity in the dehumidification area 8 is maintained high.

In order to release moisture from the dehumidifying rotor 1 in the regeneration area 17, it is necessary to heat the airflow by the heater 16. However, the passage 2 in the purge area 15 is heated in the regeneration area 17 and the passage 2 in the purge area 15 is heated. Is preheated by heat reception, the heating input by the heater 16 can be reduced accordingly, and the energy efficiency is improved. By using the dehumidifying rotor 1 efficiently in this manner, the amount of circulating air for forming a dry atmosphere and the amount of air for regeneration can be reduced, and the size of the blowers 13 and 21 can be reduced.

8 is blown into the blower 21 and flows through the regeneration air passage 18. That is, the dehumidifying rotor 1 uses a part of the indoor air.
Thus, a part of the indoor air is exhausted to the outside and the room can be ventilated. In this case, a part of the air in the room is used to regenerate the dehumidifying rotor 1 and exhausted to the outside of the room. Therefore, when the replenished air has a high humidity, the humidity in the room does not decrease so much, but it is effective when the air outside is dry or ventilation is required.
