The purge section (18a) on the outlet side communicates with an air introduction passage (21) provided with a regeneration blower (blower means) (20). On the other hand, the suction section (18a) on the suction side does not show a specific structure, but communicates with the regeneration chamber (16) via a communication chamber (17) provided at the top of the cover (15). . The regeneration chamber (16) communicates with the air discharge passage (22).
For this reason, the outside air sent to the air introduction passage (21) crosses the adsorption rotor (10) between the two purge sections (18a) when flowing through the seal passage (18), and further from the communication chamber (17). Reproduction room (16)
And then discharged from the air discharge passage (22).

The regeneration air passage (23) is a communication chamber (17) which is an upstream portion with respect to the regeneration position of the adsorption rotor (10), and a downstream portion with respect to the regeneration position of the adsorption rotor (10). The air discharge passage (22) is partially adjacent to the air discharge passage (22). That is, the regeneration air passage (23)
The upstream side and the downstream side of the suction rotor (10) are at least partially adjacent to each other.

In the cover (15), an electric heater (24) and a catalyst structure (25) are provided. The electric heater (24) includes a first heater (24a) disposed upstream of the regeneration position of the adsorption rotor (10) in the regeneration air passage (23), and an adsorption rotor (10) in the regeneration air passage (23). ) Located downstream of the playback position
The catalyst structure (25) is arranged near the second heater (24b). Specifically, the first heater (24a) is disposed in the communication chamber (17), and the second heater (24b)
Are arranged in the air discharge passage (22) and are adjacent to each other with a thin partition plate therebetween.

As described above, as a feature of the first embodiment, the regeneration air passage (23) is configured such that the upstream side and the downstream side of the adsorption rotor (10) are at least partially adjacent to each other. And the first heater (24a) and the second heater (24b)
Each is disposed in the regeneration air passage (23) so as to be adjacent to each other.

The first heater (24a) heats the adsorption rotor (10) to about 200 ° C. through the air flowing through the regeneration air passage (23) to remove odorous or harmful components from the adsorption rotor (10). And the adsorption rotor (10) is regenerated.
The second heater (24b) heats the air containing the odorous and harmful components desorbed from the adsorption rotor (10) and the catalyst structure (25) to about 300 ° C. ) To make odorous or harmful components odorless or harmless.

Although not shown, the catalyst structure (25) has, for example, a honeycomb shape (or other various shapes) having a large surface area by forming a large number of hexagonal air passage holes.
The catalyst layer can be formed on the surface of the base material. The catalyst, for example, Al ₂ O ₃ , ZrO ₂ , CeO ₂ , SiO ₂ and at least one metal oxide selected from zeolite or a mixture of the metal oxide and a composite oxide of the metal as a carrier, The carrier contains Ag, Pd, Pt, Mn and Rh as catalyst components.

Then, it is activated by being heated to about 300 ° C. or more, and decomposes odorous or harmful components to make them odorless or harmless.

As shown in FIG. 4, which is a partially enlarged view of FIG. 1, the electric heater (24) has, for example, a rod-shaped heating element integrated with a large number of heat transfer fins to increase the heat transfer area. can do. The specific shape and structure of the heating element may be appropriately set according to the shape of the portion where the electric heater (24) is arranged, and for example, a sheath heater, a semiconductor heater, a ceramic heater, or the like may be used.

The electric heater (24) and the catalyst structure (25) can be integrated. In this case, for example, if a catalyst layer is formed on the surface of the heat transfer fins of the electric heater (24), Good. As shown in the figure, the catalyst structure (2

When the catalyst layer is formed on the surface of (24), the size of the device can be reduced by reducing the installation space.

In the above configuration, when the regenerative blower (20) is driven, the outside air is blown from the air introduction passage (21) to the seal passage (18) as shown schematically in FIGS. Then, after passing through the first heater (24a) in the communication chamber (17), the air flows into the regeneration chamber (16). After passing through the adsorption rotor (10) in the regeneration chamber (16), this air passes through the air discharge passage (22) and passes through the second heater (24b).
And is discharged outside through the catalyst structure (25) (FIG. 1).
Solid arrow airflow).

In the first embodiment, the air purification is performed by using a portion (adsorption portion) where the adsorption rotor (10) is out of the cover (15). Then, when the adsorption section has sufficiently adsorbed the odorous component and the harmful component and almost reached the saturated state,
The adsorption rotor (10) is rotated to perform regeneration in the regeneration chamber (16).

-Operating operation- Next, the operating operation of the air purification device (1) will be specifically described.

First, during the air purification operation, the drive motor (12)
With the suction rotor (10) stopped,
Start (2). Then, in this air purification device (1), the regeneration section located inside the regeneration chamber (16) is formed in a narrow area, and the adsorption section located outside the regeneration chamber (16) is formed in a wide area. Is efficiently performed using the wide adsorption portion, and odor components and harmful components are removed from the indoor air.

On the other hand, if the air purification performance of the suction rotor (10) decreases in this state, the drive motor (12) is started to rotate the suction rotor (10) by a predetermined angle, and the regeneration blower (20) and the electric heater Power is supplied to (24) to start the regeneration process of the suction rotor (10). And when the reproduction of the part in the reproduction room (16) ends,
The suction rotor (10) is again rotated by a predetermined angle to reproduce the next portion, and this partial reproduction is repeated several times to reproduce the entire suction rotor (10).

When the adsorption rotor (10) is regenerated, the electric heater (2
The flow of air when power is supplied to 4) to start the regeneration blower (20) will be specifically described. First, outside air flows from the air introduction passage (21) through the seal passage (18). Seal passage (1
In (8), the air flows from the purge section (18a) on the blow side to the purge section (18a) on the suction side across the adsorption rotor (10). At this time, since the air passing through the adsorption rotor (10) is at room temperature, odor components and harmful components attached to the adsorption rotor (10) are not desorbed in the seal passage (18), and the outside air is already heated. It passes while absorbing heat from the suction rotor (10).

The air that has entered the purge section (18a) on the suction side flows into the communication chamber (17) provided at the upper part in the cover (15), and is further heated by the first heater (24a) that has already generated heat. Heated. The hot air passes through the suction rotor (10). As the high-temperature air passes through the adsorption rotor (10), the adsorption rotor (1) is formed in the regeneration chamber (16).
Odorous and harmful components are eliminated from 0). In addition, these desorbed components are contained in the regeneration air, and the air exhaust passage (22)
Flows through. At this time, since the second heater (24b) is heated and the catalyst is activated, these components desorbed from the adsorption rotor (10) are oxidatively decomposed and deodorized or made harmless.

In the first embodiment, when air passes from the right to the left in FIG. 1 through the adsorption rotor (10) in the regeneration chamber (16) (see solid arrows), odor components and harmful components are desorbed. However, since the airflow (see the dashed arrow) flowing through the seal passage (18) at both side edges of the regeneration chamber (16) acts as a shield,
There is no odor from the regeneration room (16) to the outside. Even if air containing odor components etc. flows out of the shielding plate (19), the air is included in the airflow flowing through the seal passage (18) and returns from the communication chamber (17) to the regeneration chamber (16). As a result, odor leakage is prevented. Similarly, the heat of the high-temperature air is also absorbed by the air flowing from the communication chamber (17) to the regeneration chamber (16). Then, the air after the regeneration of the adsorption rotor (10) passes through the catalyst structure (25), and flows out of the air exhaust passage (22) as clean air in which odor components and harmful components are decomposed. Released.

According to the first embodiment, when the adsorption rotor (10) is periodically regenerated, the air purification performance can be reduced without replacing the adsorption rotor (10). And high purification performance can be maintained.
Mold spores and airborne bacteria also adhere to the adsorption rotor (10) at a considerable rate, but they can be killed by heating during regeneration of the adsorption rotor (10). The odor generated due to the cause can be suppressed.

Further, in the first embodiment, the cover (15) is formed in a relatively narrow area, and the area of the portion used for air purification is increased. Can be secured.

During regeneration of the adsorption rotor (10), the air inside the regeneration chamber (16) is discharged from the air discharge passage (22) while introducing outside air from the air introduction passage (21). Therefore, if steam is generated by heating the adsorption rotor (10) during regeneration, the steam is also discharged. Therefore, even if the device (1) is cooled down to room temperature after the end of the regeneration, it is possible to prevent dew formation in the device (1). For this reason,
It is also possible to prevent mold and rust from occurring in the device (1) due to dew condensation, and prevent water drops from leaking into the room.

The feature of the first embodiment is that the first
Since the heater (24a) and the second heater (24b) are arranged in one place, for example, the heater (24
a, 24b), when heat insulating material is attached to the cover (15) near the cover (15), the heat dissipation prevention structure can be integrated in one place of the cover (15). You can enhance the nature. For this reason, the thermal insulation effect of the device (1) can be enhanced to maintain the decomposition performance at a high level.

-Modification of Embodiment 1- In the air purification device of Embodiment 1 described above, after all parts of the suction rotor (10) (parts outside the cover (15)) are subjected to air purification, regeneration is summarized. While purifying the air using a part of the suction rotor (10), the other part (that is, in the regeneration chamber (16)) regenerates the suction rotor (10) at the same time. It may be. Then, it is possible to easily continue the air purification operation without interruption.

In this case, for example, a timer may be used to start the drive motor (12) and rotate the suction rotor (10) by a predetermined angle when the air purification operation is performed for a predetermined time, or the suction rotor (10) may be used. The concentration of odorous and harmful components in the air downstream of the adsorption section is detected, and when the concentration exceeds a predetermined value, it is determined that purification performance has decreased, and the drive motor (12) is started. Is also good. When using a timer, for example, air purification is performed during the activity time of a person during the day, and regeneration is performed when no person is present at night, or adsorption and regeneration are performed several times a day. And so on.

Further, in addition to the catalyst structure (25) of the first embodiment, an adsorption rotor is provided in the communication chamber (17) and the regeneration chamber (16).
A catalyst structure (25) may be additionally provided at a position on the upstream side of (10), as indicated by a virtual line. In this case, since the catalyst structure (25) is located on the upstream side of the adsorption rotor (10), clean air for regeneration passes through the adsorption rotor (10), and odor components and the like are removed. Desorption is performed effectively.

[0056]

Second Embodiment Next, a second embodiment shown in FIG.
Will be described. The second embodiment is provided with a heat exchanger (26) for performing heat exchange between the air flowing through the air introduction passage (21) and the air discharged from the air discharge passage (22). 5 is a schematic diagram showing a schematic air flow. As the heat exchanger (26), for example, a helical tube heat exchanger with radiating fins, a double tube heat exchanger, or the like can be used.

As shown in the figure, the outside air is first supplied to the heat exchanger (2).
As it passes through 6), it is heated by the heat of the discharged treated air. The outside air is not heated to such an extent that the odor components and the like of the adsorption rotor (10) are desorbed by this heat, and passes through the adsorption rotor (10) when flowing through the seal passages (18) on both sides of the regeneration chamber (16). Only. Thereafter, the air is heated to a high temperature by the first heater (24a) when passing through the communication chamber (17) and enters the regeneration chamber (16) as in the first embodiment. Therefore, odor components and harmful components are desorbed from the adsorption rotor (10) by the high-temperature air.

Thereafter, the air becomes clean air from the regeneration chamber (16) through the air discharge passage (22), and passes through the heat exchanger (26) when discharged outside. Therefore, the air after the treatment is cooled by applying heat to the air introduced from the outside and then discharged outside the machine.

According to the second embodiment, in addition to the effects of the first embodiment, a heat exchanger (26) is provided to apply the heat of the discharged air to the introduced air. Even if the capacity of the electric heater (24) is suppressed, air can be efficiently heated, and odor components and harmful components can be removed from the adsorption rotor (10) and the catalyst can be sufficiently activated. Therefore, energy can be saved.
