Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air processing apparatus for processing indoor air mainly into a dry atmosphere.

[0002]

2. Description of the Related Art Among the above-mentioned devices, there is known a drying and ventilating device which makes a bathroom a dry atmosphere and can be used as a drying room for clothes and the like. A general dry ventilator has a configuration as disclosed in JP-A-4-240495. That is, it is constituted by a blower that circulates indoor air while being heated by the heating means, and a blower that intermittently discharges humid air inside the room to the outside.

[0003] This type of device requires a fan for circulation and a fan for exhaust, and the amount of heat lost due to ventilation is large, so that the heating means also has a large capacity, so that the whole becomes large and the energy efficiency is low. It's not very good. Therefore, Japanese Utility Model Laid-Open No. 6-10772 and Japanese Patent Application Laid-Open No.
As disclosed in JP-A-56-56 and JP-A-8-35696, an apparatus using a dehumidifying rotor capable of reversibly absorbing and releasing moisture has been developed.

[0004] The dehumidifying rotor itself used in this type of apparatus has been conventionally used for a plastic pellet drying apparatus and the like, and is formed by winding a corrugated material or a honeycomb material to which a hygroscopic agent such as silica gel is adhered. It has a cylindrical shape. The drying and ventilating apparatus disclosed in Japanese Patent Application Laid-Open No. 8-35696 is provided with a circulating air path for circulating indoor air by a blower, and an exhaust air path opening outside the room. It is configured to continuously pass through both the circulation air passage and the exhaust air passage.

[0005] A heating means for dehumidifying the dehumidifying rotor to regenerate the dehumidifying ability is provided at an inlet portion of the exhaust air passage into the passage of the dehumidifying rotor. Most of the indoor air taken into the circulation air passage passes through the dehumidifying region of the rotating dehumidifying rotor, is processed into dry air, and is blown into the room. A part of the indoor air taken into the circulation air passage passes through the purging area of the dehumidifying rotor, is heated by the heating means, passes again through the regeneration area of the dehumidifying rotor, and is exhausted outside the room. Due to the passage of the heated air, the dehumidifying rotor in the regeneration area is dehumidified and regenerated. As a result, the room becomes a dry atmosphere with ventilation, and for example, the bathroom can be used as a drying room for clothes and the like.

[0006]

The drying and ventilating apparatus using the conventional dehumidifying rotor as described above uses a part of the air in the room to regenerate the dehumidifying rotor and exhausts the air outside the room. Air will be replenished from the outside. Therefore, when the replenished air has a high humidity, the humidity in the room does not decrease so much, and depending on the humidity of the replenished air, it takes a long time to make the room a dry atmosphere. These problems can be solved by not using indoor air for regeneration of the dehumidifying rotor. However, in order to achieve this with one blower, it is necessary to adjust the pressure loss in the dehumidification-side and regeneration-side air passages, balance the air flow, and perform a very troublesome design, and sometimes In some cases, it is necessary to provide a useless pressure loss resistance in the flow path.

[0014]

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 and 2 utilizes a dehumidifying rotor 1 having a reversible moisture absorbing and releasing function as shown in FIGS. As shown in FIGS. 3 and 4, a dehumidifying rotor 1 applied to this apparatus is formed by rolling 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, and is formed into a cylindrical shape. In this configuration, a multilayer 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 (0.5 rpm to
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 incorporated in a main body casing 6 that is located outside the suction port 9 of the dehumidification air passage 11 and on the outside of the body. The dehumidifying air passage 11 has the suction port 9 as an inlet end and the blower 1
3 through the passage 2 in the dehumidifying area 8 of the dehumidifying rotor 1 to the outlet 1 from the ventilation hole formed in the mounting base plate 7 as the outlet end.
It is configured as a series of passages leading to zero. Dehumidifying air passage 1
The suction side of the one blower 13 communicates with an air supply passage 14 that opens to the outside of the room at the back of the main body casing 6.
An air filter 15 for purifying passing air and an opening / closing damper 16 for opening and closing the outdoor opening are provided at the outdoor opening of the air supply passage 14. The air processing apparatus according to the first embodiment has a configuration in which the main body casing 6 is formed into a hexahedron having no irregularities on the outdoor side, since the air processing apparatus according to the first embodiment is configured to be inserted into a mouth frame of a ventilation opening opened in a bathroom wall, for example. I have.

In the main casing 6, a part of the path on the inlet end side is formed by a passage 2 in a specific region 17 (hereinafter referred to as a purge region) in a preceding stage in the rotation direction of the passage 2 in the dehumidification region 8 in the dehumidification rotor 1. And a passage of another specific region 19 (hereinafter referred to as a regeneration region) at a subsequent stage in the rotation direction of the purge region 17 of the dehumidifying rotor 1 again via a heating path provided with a heater 18 as a heating means. 2, a regeneration air passage 20 having an outlet end opened outside the room. A suction port 21 which is an inlet end of the regenerating air passage 20 is opened at a rear side which is an outdoor side of the main casing 6, and an outlet 22 which is an outlet end of the regenerating air passage 20 is connected to the main casing 6.
Open on the lower surface, which is the outdoor side. The regeneration air passage 20 is configured to be narrower than the dehumidification air passage 11 for processing the indoor air in the entire flow path, and a blower 2 that forms an airflow from the suction port 21 to the air outlet 22 in the regeneration air path 20 near the air outlet 22.
3 are attached. This blower 23 is used for the dehumidifying air passage 11.
Is independent of the blower 13 including the motor 24, and blows a smaller air volume than 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 17 and a regeneration area 19. The dehumidification area 8 occupies the widest angle of about 230 degrees on the entire end face, the purge area 17 has an angle of about 50 degrees, and the regeneration area 19 has an angle of about 80 degrees.

The heating path of the regeneration air path 20 is the dehumidifying rotor 1
Is constituted by a heating box 25 mounted on a mounting base plate 7 which slides in one end in an airtight state. The heating box 25 is provided on one end side of the dehumidifying rotor 1 through an opening formed in the mounting base plate 7.
Of the passage 2 and the end of the passage 2 of the reproduction area 19 are connected to each other. In the heating box 25, a heater 18 for heating an air flow passing through the section is incorporated. Heating box 2
In the regeneration area 19 on the other end surface side of the dehumidification rotor 1 facing to the exhaust pipe 5, an exhaust connection part 26 constituting a part of the regeneration air passage 20 is attached so as to sandwich the dehumidification rotor 1.
The end face side of the dehumidification rotor 1 of the exhaust connection part 26 is open, and the end face of the dehumidification rotor 1 can slide through a seal.

The air processing apparatus having the above-described structure is inserted from the indoor side into a ventilation opening or the like provided through a wall separating the inside and outside of a room such as a bathroom, and is connected to the air inlet 21 of the regeneration air passage 20 and the air blowing device. The outlet 22 and the outdoor opening of the air supply passage 14 are mounted so as to open toward the outside (often outdoors). To make the room dry, the air supply passage 1
4 is closed by the opening / closing damper 16 and the blower 13
23, the dehumidifying rotor 1 and the heater 18 are operated. By the operation of the blower 13, room air is sucked into the dehumidifying air passage 11 from the suction port 9 through the air purification filter 12. The sucked air is blown into the room again from the outlet 10 through the passage 2 in the dehumidifying area 8 of the dehumidifying rotor 1 rotated by the blower 13. On the other hand, the outside air sucked from the suction port 21 of the regeneration air passage 20 by the operation of the blower 23 is sent to the heating box 25 via the passage 2 in the purge area 17 of the rotating dehumidifying rotor 1, and Heater 1
The air is heated again at 8 and flows again into the passage 2 of the regeneration area 19 of the dehumidifying rotor 1 from the opposite direction, and is exhausted from the outlet 22 to the outside through the exhaust connection 26. Since the dehumidifying air passage 11 and the regenerating air passage 20 are independent from each other over the entire passage, the state quantity of the indoor air changes but little ventilation is performed.

The dehumidifying rotor 1 is rotating at a low speed, and the passages 2 in the dehumidifying region 8 are sequentially shifted to the regeneration region 19, and the passages 2 in the regeneration region 19 are sequentially purged in the purge region 17.
, And the passage 2 in the purge area 17 performs a continuous operation of shifting to the dehumidification area 8. The high-temperature airflow heated by the heater 18 flows into the passage 2 of the regeneration area 19 which constitutes a part of the regeneration air passage 20, and the dehumidification rotor 1 of the portion is dehumidified into the outside air which is continuously taken in. I have. The passage 2 of the dehumidifying rotor 1 that has been dehumidified by passing through the regeneration area 19 and provided with the dehumidifying ability is heated to a high temperature by receiving the heat of the heater 18, but is cooled by the outside air blown in the next purge area 17. Is done. The passage 2 of the dehumidification rotor 1 that has been cooled after passing through the purge region 17 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 in the dehumidifying rotor 1 that has absorbed moisture in the dehumidifying area 8 is released again in the regenerating area 19 to be regenerated, and the dehumidifying ability is provided.

In this air processing apparatus, the indoor air is not used for regeneration of the dehumidifying rotor 1, but is dehumidified and discharged to the 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. Since the air flow is formed in the regeneration air passage 20 by the action of the suction side of the blower 23, the air flow flowing in the regeneration air passage 20 is formed in the gap between the regeneration air passage 20 and the dehumidification rotor 1, particularly, as shown in FIG. A high dehumidification performance can be maintained without blowing high-humidity air into the dehumidification air passage 11 side without blowing out into the main body casing 6 from the gap S between the air and the dehumidification rotor 1.

If the operation of the dehumidifying rotor 1 and the heater 18 is stopped and only the blower 13 is operated, the indoor air can be circulated through the air purifying filter 12 through the dehumidifying air passage 11 to function as an air purifying device. Can be. In addition, if the opening / closing damper 16 is opened to open the air supply passage 14, a ventilation operation by introducing outside air can also be performed. 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 the first embodiment, the dehumidification rotor 1 heated in the regeneration region 19 and having a raised surface temperature is cooled by the passage of outside air in the next purge region 17 and reaches the dehumidification region 8, so that the dehumidification capacity in the dehumidification region 8 is improved. Will be kept high.

To release moisture from the dehumidifying rotor 1 in the regeneration area 19, it is necessary to heat the airflow by the heater 18. However, the passage 2 in the purge area 17 is heated in the previous regeneration area 19 and the passage 2 in the purge area 17 is heated. Is preheated by the heat reception, the heating input by the heater 18 can be reduced accordingly, and the energy efficiency can be 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 23 can be reduced. In particular, since the blowers 13 and 23 are configured as independent blowers, the most suitable blowers 13 and 23 in view of the pressure loss in the dehumidification-side and regeneration-side air passages.
There is no need to adjust the pressure loss in the air path to balance the air volume, and there is no need to add useless pressure loss resistance to the flow path. And the manufacturability is improved.

Is reduced by a slope 28 or a curved surface corresponding to the area of the end face of the dehumidifying rotor 1 with respect to the feeding portion 27 for feeding the passage 2 in the regeneration area 19 of the dehumidifying rotor 1. By adopting such a shape of the heating box 25, the amount of the heated air heated by the heater 18 gradually decreases in the flow direction. The end face of the dehumidifying rotor 1 facing the upstream side of the flow has a large area and is the end of the regeneration process, and it is necessary to increase the amount of air and increase the temperature in order to complete the regeneration. Further, the end face of the dehumidifying rotor 1 facing the downstream side of the flow has a small area,
Moreover, since it is the first part of the regeneration process and the amount of moisture is large, the regeneration is easily performed even if the air amount is reduced and the temperature is lowered. Such characteristics of the dehumidifying rotor 1 can be effectively utilized by adopting the shape of the heating box 25 as described above, and efficient regeneration of the dehumidifying rotor 1 can be realized, so that the dehumidifying amount can be increased.
