A moisture absorption rotor 8 is interposed between the moisture absorption ventilation passage 40 and the regeneration ventilation passage 41. The moisture absorbing rotor 8 is formed by impregnating a band-shaped sheet-like base material such as a ceramic sheet having a predetermined width and length with a solution in which zeolite as an adsorbent is dissolved, and impregnating the zeolite with the solution. , 1mm high on a supported strip-shaped flat sheet
After being subjected to corrugation processing of about 1.5 mm and bonded and integrated, it is formed in a substantially cylindrical shape by winding in the length direction. Therefore, when the moisture absorbing rotor 8 is viewed from the front, there are many honeycomb-shaped gaps similar to the cross section of the corrugated cardboard, and the design is such that the pressure loss of air passing axially through the moisture absorbing rotor 8 is reduced. Have been. The moisture absorbing rotor 8 is connected to a motor 9 at a central portion thereof, and rotates around a motor shaft when the motor 9 is driven.

And a reproduction fan 11 are provided. Regeneration ventilation path 41
The regeneration heater 7 is incorporated between the moisture absorption rotor 8 and the regeneration fan 11 inside. Downstream of the moisture absorption rotor 8 in the moisture absorption ventilation path 40 and the regeneration ventilation path 41, a ventilation path switching damper 12 is provided so that the direction of the damper 12 can be changed according to the use of the humidity controller. An outdoor air suction port 5 facing the outside and a second indoor air outlet 6 facing the room side communicate with each other through a ventilation path 42.

Next, the operation of the conventional dehumidifier during the dehumidifying operation will be described with reference to FIG. 8, where the arrows in the figure indicate the flow of air. First, the damper 12 is connected to the first ventilation air passage 3 through the moisture absorption ventilation passage 40 and the regeneration ventilation passage 4.
1 is switched so as to communicate with the outdoor air outlet 4. In this state, power is supplied to the motor 9, the moisture absorption fan 10, the regeneration fan 11, and the regeneration heater 7. Moisture absorption fan 10
Accordingly, the moisture in the room air guided from the first room air suction port 1 to the moisture absorption ventilation passage 40 is absorbed by the moisture absorption rotor 8, and the dried air is exhausted from the first room air outlet 3.

On the other hand, the room air flowing from the second room air suction port 2 by the regeneration fan 11 is heated by the regeneration heater 7 and passes through the moisture absorption rotor 8. At this time, the moisture in the moisture absorbing rotor 8 that has absorbed moisture in the moisture absorbing ventilation passage 40 is released, and wet air containing a large amount of moisture is discharged from the outdoor air outlet 4. Moisture absorption repeated by the moisture absorption rotor 8,
The separation, the exhaust of the dry air into the room, and the discharge of the humid air to the outside of the room gradually remove the moisture of the room air and dehumidify the room air. Since the indoor air is discharged from the outdoor air outlet 4, the outdoor air flows from the outdoor air inlet 5 through the ventilation path 42 into the room from the second indoor air outlet 6.

Next, the operation of the humidifying operation will be described with reference to FIG. In this case, the damper 12 is connected to the moisture absorbing ventilation passage 4.

On the other hand, the room air flowing from the second room air suction port 2 by the regeneration fan 11 passes through the moisture absorption rotor 8 which is heated by the regeneration heater 7 and rotates. At this time, moisture is released from the moisture absorbing rotor 8 that has absorbed moisture in the moisture absorbing ventilation passage 40, and wet air containing a large amount of moisture is discharged from the first indoor air outlet 3. Therefore, the interior air is gradually supplied with moisture and humidified by the repeated absorption and desorption of moisture by the moisture absorption rotor 8, the exhaustion of the dry air to the outside, and the exhaustion of the humid air to the interior of the room.

In the conventional humidity controller, in order to perform an efficient dehumidification operation, for example, during the dehumidification operation, more moisture in the room air is absorbed by the moisture absorption rotor 8. It is desirable to absorb moisture and return air having a low absolute humidity to the room and exhaust unnecessary moisture to the outside. Similarly, at the time of the humidification operation, it is desirable that more moisture in the room air be absorbed by the moisture absorption rotor 8, air having a low absolute humidity is exhausted outside the room, and necessary moisture is returned to the room. Further, in order to sufficiently exhibit the moisture absorbing performance of the moisture absorbing rotor 8, it is desirable that the moisture absorbing rotor 8 heated by the regeneration heater 7 be rapidly cooled to a temperature as close to room temperature as possible while passing through the regeneration region. .

However, for the above-mentioned reason, when the amount of air to be absorbed is increased in order to adsorb more moisture or to cool the rotor 8 rapidly, the wind speed of the air passing through the rotor 8 is also increased. 100% of the moisture contained in the air while the indoor air passes through the moisture absorbing rotor 8
It becomes difficult to absorb moisture. In addition, when humidifying operation is used in winter, the amount of dry air flowing into the room from the outside due to natural ventilation increases as the amount of indoor air exhausted outside increases, which hinders humidification performance. There is.

The present invention has been made in view of the above problems, and has as its object to provide a humidity controller that can increase the efficiency of moisture absorption, humidification, and dehumidification and increase the amount of regeneration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a humidity controller according to the present invention will be described below with reference to the drawings. 7 to FIG.
The same members or those having the same functions as those of 1 are denoted by the same reference numerals, and detailed description thereof will be omitted. First, a first embodiment of the humidity controller according to the present invention will be described. The operation of the humidity controller according to the present embodiment at the time of the ventilation operation is not much different from that of the conventional humidity controller, and thus the case of the dehumidification and humidification operation will be described.

FIG. 1 is a schematic configuration diagram of a humidity controller according to the first embodiment. The humidity controller of the present embodiment has a plurality of moisture absorbing rotors, and constitutes a moisture absorbing circuit through which the same air passes. During the dehumidifying or humidifying operation of the conventional humidity controller, the amount of moisture in the indoor air taken into the main body from the first indoor air suction port 1 and absorbed while passing through the moisture absorbing rotor 8 is determined by the moisture absorption. The air flow increases as the air flow increases, but at the same time, the passing wind speed increases, so that the amount of water that passes through without being absorbed increases. Therefore, the moisture absorption and desorption of the air in the air repeated by the moisture absorption rotor 8 and the exhaustion of the dry air to the inside and outside of the room and the exhaustion of the humid air to the inside and outside of the room by the moisture absorption rotor 8 can provide an appropriate dehumidification or humidification effect. In a humidifier, the amount of moisture that passes through the moisture absorption rotor 8 without being absorbed is reduced, and unnecessary moisture is removed during dehumidification, and more moisture in the air required during humidification is released to the outside or the interior of the humidifier. Connect.

Therefore, as shown in FIG. 1, the first moisture absorbing rotor 16 and the second moisture absorbing rotor 17 are arranged to form a single moisture absorbing circuit in which the same air passes through each moisture absorbing portion. In this embodiment, the moisture absorbing rotors 16, 17
Although the case where two are mounted is shown, the number is not limited to two, and the greater the number, the higher the moisture absorption efficiency. The first moisture absorption rotor 16, the first indoor air suction port 20, the first regeneration fan 18, and the first regeneration heater 14 constitute a first regeneration circuit, and the second moisture absorption rotor 17 and the second interior air intake The opening 21, the second regeneration fan 19, and the second regeneration heater 15 constitute a second regeneration circuit. In order to simultaneously rotate the respective moisture absorbing rotors 16 and 17 in the same direction, a coaxial motor 9 for the moisture absorbing rotor is provided.

Next, the operation of the humidity controller in the first embodiment will be described with reference to FIG. In the case of the dehumidifying operation, the first and second regeneration circuits communicate with the outdoor air outlet 4 and the moisture absorption circuit communicates with the first indoor air outlet 3 by the damper 12, as shown in FIG. In this state, the moisture absorption fan 10, the first regeneration fan 18, the second regeneration fan 19, the first regeneration heater 1
4. Energize the second regeneration heater 15 and the motor 9.

The indoor air guided into the moisture absorption circuit from the first indoor air suction port 1 by the moisture absorption fan 10 has the moisture contained therein adsorbed by the first moisture absorption rotor 16 and passes therethrough without being adsorbed there. The absorbed moisture is supplied to the second moisture absorbing rotor 17.
The air that has been adsorbed when passing through and is in a dry state containing almost no water is discharged from the first indoor air outlet 3 into the room.

On the other hand, the room air guided into the regeneration circuit from the first room air suction port 20 by the first regeneration fan 18 is:
After being heated by the first regeneration heater 14, the first moisture absorbing rotor 1
Go through 6. At this time, the moisture adsorbed by the first moisture absorption rotor 16 evaporates and separates when the heated air passes, and becomes a state containing a large amount of moisture, and is discharged from the first outdoor air outlet 4 to the outside. . Similarly, in the regeneration system of the second moisture absorption rotor 17, the room air guided from the fourth indoor air suction port 21 is heated by the second regeneration heater 15 by the second regeneration fan 19, and the second moisture absorption rotor 17 is heated. When passing through, the air becomes highly humid and is discharged from the first outdoor air outlet 4 to the outside.

Next, in the case of the humidification operation, as shown in FIG. 3, the damper 12 is switched to a state in which the regeneration circuit communicates with the first indoor air outlet 3, and the moisture absorption circuit communicates with the outdoor air outlet 4. . In this state, electricity is supplied to the moisture absorption fan 10, the first regeneration fan 18, the second regeneration fan 19, the first regeneration heater 14, the second regeneration heater 15, and the moisture absorption rotor motor 9. As in the case of the dehumidifying operation, the indoor air guided into the moisture absorption circuit from the first indoor air suction port 1 by the moisture absorption fan 10 passes through the first moisture absorption rotor 16 so that the moisture contained therein is removed by the first moisture absorption rotor. The water that has been adsorbed by the air passage 16 and passed therethrough without being adsorbed is adsorbed when passing through the second moisture absorption rotor 17, and the air that has become dry and contains almost no water is discharged from the first outdoor air outlet 4. Released outside the room.

On the other hand, the indoor air guided into the regeneration circuit from the third indoor air suction port 20 by the first regeneration fan 18 is:
After being heated by the first regeneration heater 14, the first moisture absorbing rotor 1
Go through 6. At this time, the moisture adsorbed in the moisture absorption circuit of the first moisture absorption rotor 16 evaporates and separates when the heated air passes, and becomes a state containing a large amount of moisture. Will be released.

Similarly, in the regeneration system of the second moisture absorbing rotor 17, the indoor air guided from the fourth indoor air suction port 21 by the second regeneration fan 19 is supplied to the second regeneration heater 15.
, And becomes high humidity air when passing through the second moisture absorption rotor 17, and is discharged from the first indoor air outlet 3 into the room. By forming a moisture absorption circuit in which the same room air passes through a plurality of moisture absorption rotors in this manner, the amount of moisture that is not adsorbed and passes through is reduced as compared with the case of a single moisture absorption rotor. And the amount of regeneration increases accordingly, so that the amount of moisture discharged from the outdoor air outlet 4 to the outside during the dehumidifying operation increases. In addition, during the humidification operation, the amount of water released into the room from the first indoor air outlet 3 increases, so that high dehumidification and humidification effects can be obtained. Further, as in the conventional case, in any case, the indoor air is discharged from the outdoor air outlet 4, so that
The outdoor air flows from the outdoor air suction port 5 through the ventilation passage 42 to the second
The air flows into the room from the indoor air outlet 6.

Next, a description will be given of a second embodiment of the humidity controller according to the present invention. The structure and operation and effect of the regeneration circuit using the humidity controller of the present embodiment are not significantly different from those of the humidity controller of the first embodiment.
A description will be given of a structure different from that of the humidity controller of the embodiment, and a moisture absorption circuit having an operational effect.

FIG. 4 is a schematic configuration diagram of a humidity controller according to the second embodiment. The humidity controller of the present embodiment is the same as the humidity controller of the first embodiment except that a cooling device is provided in a ventilation path between the moisture absorbing rotors. In the moisture absorption circuit of the humidity controller in the first embodiment, the first moisture absorption rotor 16 is heated by the regeneration heater 7 while passing through the regeneration area.
In the moisture absorption area, while room air guided into the main body from the first indoor air suction port 1 passes through the moisture absorption rotor 16,
When the heat from the first moisture absorption rotor 16 is transmitted and reaches the second moisture absorption rotor 17, the air temperature has risen.
In some cases, it may not be able to exhibit sufficient moisture absorption performance.

Therefore, in the second embodiment, as shown in FIG. 4, a first cooling ventilation passage 24 is provided between the first moisture absorbing rotor 16 and the second moisture absorbing rotor 17. The first cooling ventilation passage 24 has a structure in which irregularities are processed inside so as to increase the surface area. The first cooling fan 25 is arranged near the first cooling ventilation passage 24, and is cooled by the cool air from the first cooling fan 25, so that the room air heated when passing through the first moisture absorbing rotor 16 is heated. Is cooled to a temperature suitable for absorbing moisture. Also, the first
For rotation of the moisture absorbing rotor 16 and the second moisture absorbing rotor 17,
A motor 22 for the first moisture absorbing rotor and a motor 23 for the second moisture absorbing rotor are provided, and the rest of the regeneration circuit, the damper 12, and the like have the same configuration as in the first embodiment.

Next, the operation of the moisture absorption circuit of the humidity controller according to the second embodiment will be described. The indoor air guided into the moisture absorption circuit from the first indoor air suction port 1 by the moisture absorption fan 10 passes through the first moisture absorption rotor 16, and when the moisture contained therein is adsorbed by the first moisture absorption rotor 16. at the same time,
The heat from the first moisture absorption rotor 16 is transmitted, and the air temperature rises. However, since the first cooling ventilation passage 24 is cooled by the cool air from the first cooling fan 25, the room air is cooled while passing through the first cooling ventilation passage 24, and reaches a temperature close to room temperature. Thereby, the second moisture absorbing rotor 1
Since the amount of moisture absorbed when passing through 7 increases, the moisture absorption efficiency can be improved.

Next, a third embodiment of the humidity controller according to the present invention will be described. FIG. 5 is a front view of a moisture absorption rotor of the humidity controller according to the third embodiment, and FIG. 6 is a cross-sectional view of a moisture absorption circuit of the humidity controller of the third embodiment. The humidity controller of the present embodiment divides the moisture absorption area of one moisture absorption rotor into a plurality of parts, provides a moisture absorption circuit that allows the same air to pass through each moisture absorption area in series, and further provides ventilation between the moisture absorption areas. A cooling device is provided on the road.

As described above, in order to sufficiently exhibit the moisture absorption performance of the rotary moisture absorption rotor in the moisture absorption area, the moisture absorption rotor heated by the regeneration heater while passing through the regeneration area is kept at room temperature as much as possible. It is desirable to cool rapidly to a temperature close to. However, if the humidifying operation is used in winter, for example, if the amount of moisture absorbed is increased, the amount of indoor air exhausted to the outside increases, and the amount of dry air flowing into the room from the outside increases by natural ventilation. In some cases. In addition, the temperature distribution in the moisture absorption area becomes high immediately after passing through the regeneration area due to the influence of heat from the regeneration heater, but it is difficult to cool down gradually as it passes through the moisture absorption area. May decrease.

Therefore, as shown in FIG.
To the regeneration area 13, the first moisture absorption area 26, and the second moisture absorption area 2.

As shown in FIG. 6, a moisture absorption circuit 46 is provided so that the same air turns so as to pass through the respective moisture absorption regions in series, and a second cooling passage is provided between the first moisture absorption region 26 and the second moisture absorption region 27. The second ventilation fan 30 and the third cooling fan 32 are provided between the second moisture absorption area 27 and the third moisture absorption area 28. In addition, each of the ventilation passages 30 and 31 is subjected to unevenness processing so as to increase the surface area, and two cooling fans 32 and 33 are arranged at positions where the respective ventilation passages 30 and 31 are cooled. I do. Thereby, the air passing through the moisture absorption region can be cooled to a temperature as close to room temperature as possible.

In the above embodiment, the moisture absorption areas 26, 27,
FIG. 28 shows a case where three divisions are performed, but as the number increases, the moisture absorption efficiency can be improved, and the number of divisions is not limited. In addition, a regenerating circuit, a damper, and the like other than the moisture absorbing circuit have the same configuration as the conventional one.

Next, the operation of the moisture absorption circuit of the humidity controller according to the third embodiment will be described. First, the moisture-absorbing air 29 guided into the moisture-absorbing circuit passes through the first moisture-absorbing region 26, during which moisture contained in the air is adsorbed, and at the same time, heat from the moisture-absorbing rotor 8 is transmitted, and the air temperature is reduced. Rises.
Then, heat is taken while passing through the second cooling ventilation passage 30 which is always cooled by the second cooling fan 32, and passes through the second moisture absorption region 27 in a cooled state. At this time, since the air temperature is rising, the moisture contained in the air is efficiently adsorbed, and at the same time, the heat from the moisture absorption rotor 8 is transmitted. Then, while passing through the third cooling ventilation passage 31 cooled by the third cooling fan 33, heat is taken again, and passes through the third moisture absorption region 28 in a cooled state, and the moisture contained in the air is removed. Is adsorbed.

The order of passage of the moisture-absorbing region through which the moisture-absorbing air 29 passes immediately after the rotating moisture-absorbing rotor 8 has passed through the regeneration region 13 is the first moisture-absorption region 26, which is a moisture-absorption region that is greatly affected by heat from the regeneration heater. First, then the second
