BACKGROUND OF THE INVENTION This invention relates to an air conditioner capable of dehumidifying and humidifying a room.

[0002]

2. Description of the Related Art The applicant of the present invention filed an earlier application (Japanese Patent Application No. 2-90).
No. 833) proposed the following air conditioner. As shown in FIG. 3, the structure is such that the surface of the porous plate 51 is arranged so as to face the ventilation passage 53 of the indoor unit 52, and the hygroscopic medium 54 is circulated to the back of the porous plate 51. . In this case, moisture is absorbed from the humid air sucked into the ventilation passage 53 by the fan 55 into the hygroscopic medium 54 through the porous plate 51, and the dehumidified air is returned to the room. The hygroscopic medium 54 is circulated between the back portion of the porous plate 51 and the reproducing portion 57 installed outdoors by the medium pump 56. The regenerator 57 includes a medium chamber 58 into which the hygroscopic medium 54 flows, a low pressure chamber 60 adjacent to the medium chamber 58 via a semipermeable membrane 59, and a vacuum pump 61 for depressurizing the low pressure chamber 60. And the absorbed water from the above room,
The hygroscopic medium 54, which has been released into the low pressure chamber 60 through the semipermeable membrane 59 and released moisture, is again supplied to the inside of the room,
This allows continuous dehumidification operation.

[0003]

However, the air conditioner described above has a drawback in that only dehumidifying operation can be performed.

The present invention has been made to solve the above-mentioned conventional drawbacks, and the purpose thereof is to effectively use the conventional constituent devices, and to carry out the dehumidification operation without causing a significant cost increase. An object is to provide an air conditioner that can perform both humidification operation.

[0005]

Therefore, in the air conditioner of the present invention, the surface of the porous plate 2 which allows the permeation of moisture is arranged on the indoor side, and the hygroscopic medium 5 is circulated on the back side thereof. An air conditioner for indoor dehumidification or humidification, which is arranged adjacent to the medium chamber 9 via a medium chamber 9 into which the hygroscopic medium 5 flows and a semipermeable membrane 10 that allows moisture to permeate. Air chamber 11 and air chamber 11
And an air pump 13 connected to the air pump 13, and a switching means 16 for switching and communicating the suction port 14 and the air outlet 15 of the air pump 13 with the air chamber 11, and the air chamber 11 further includes the air chamber 11. When 11 is connected to the suction port 14 of the air pump 13, the air chamber 11 is hermetically closed, while the air chamber 11 is blown out by the air outlet 15 of the air pump 13.
It is characterized in that a check damper 12 is provided for communicating with the atmosphere while increasing the pressure of the air chamber 11 when connected to the.

[0006]

In the above air conditioner, if the air chamber 11 is connected to the suction port 14 of the air pump 13 to depressurize the air chamber 11, moisture is released from the hygroscopic medium 5 through the semipermeable membrane 10. Therefore, dehumidification is performed on the porous plate 2 side.

On the other hand, by switching the switching means 16, the air chamber 1
1 to the air outlet 15 of the air pump 13 to connect the air chamber 11
When is pressurized, moisture in the pressurized air is absorbed by the hygroscopic medium 5 through the semipermeable membrane 10. Therefore, the porous plate 2 side is humidified to release the moisture.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes an indoor unit. In this indoor unit 1, a porous plate 2 which allows passage of moisture is arranged with its surface facing an air passage 3. Has been done. This indoor unit 1 has a fan 4
With this fan 4, the indoor air is circulated in the ventilation passage 3. The hygroscopic medium 5 flows into the back portion of the porous plate 2, and the hygroscopic medium 5 is circulated between the moisture absorbing / releasing portion 6 provided on the outdoor side and the back portion of the porous plate 2. It is supposed to circulate on road 7. Reference numeral 8 is a medium pump for circulating the hygroscopic medium 5.

The moisture absorbing / releasing section 6 has a medium chamber 9 into which a hygroscopic medium flows in, and an air chamber 11 arranged adjacent to the medium chamber 9 with a semipermeable membrane 10 allowing the passage of moisture. Have.
The air chamber 11 is provided with a check damper 12, but the check damper 12 is closed when the pressure in the air chamber 11 becomes low, and when the pressure in the air chamber 11 exceeds a certain level. In addition, it is opened at an opening that maintains the pressure.

On the other hand, 13 is an air pump, and its suction port 14 and blow-out port 15 have a four-way switching valve (switching means) 1
6 are connected to a pair of ports. The other pair of ports of the four-way switching valve 16 are connected to a communication passage 17 communicating with the air chamber 11 and an atmosphere opening passage 18, respectively. That is, the four-way switching valve 16 allows the suction port 14 and the outlet port 15 of the air pump 13 to be switched and communicated with the communication passage 17 and the atmosphere opening passage 18.

As the hygroscopic medium 5 used in the above, 90% ethylene glycol, 40% lithium chloride and the like can be mentioned, but the hygroscopic medium 5 is not particularly limited thereto.

Next, the operating state of the air conditioner will be described. First, at the time of dehumidifying operation, as shown in FIG. 2, the suction port 14 of the air pump 13 is connected to the air chamber 11 via the communication passage 17, and the air outlet 15 is connected to the atmosphere opening passage 18, respectively. Is reduced to a state Pc close to a vacuum (the check damper 12 is closed). Then, due to the pressure difference (Po-Pc) from the pressure Po of the hygroscopic medium 5, the air chamber 11 passes from the hygroscopic medium 5 through the semipermeable membrane 10.
Water is released inside. At this time, in the indoor unit 1, moisture is absorbed from the humid air sucked into the ventilation passage 3 by the fan 4 to the hygroscopic medium 5 through the porous plate 2, and the dehumidified air is returned to the room. At this time, in order to improve the indoor dehumidifying ability, the moisture absorbing / releasing section 6
It is necessary to improve the ability to remove water from the hygroscopic medium 5 in step 1. However, for this purpose, the hygroscopic medium 5 may be heated in the medium chamber 9.

On the other hand, during the humidifying operation, as shown in FIG. 1, the air outlet 15 of the air pump 13 is connected to the air chamber 11 via the communication passage 18, and the suction inlet 14 is connected to the atmosphere open passage 18. The pressure Pc in the air chamber 11 is increased (the check damper 12 is opened). Then, due to the pressure difference (Pc-Po) from the pressure Po of the hygroscopic medium 5, moisture is absorbed into the hygroscopic medium 5 through the semipermeable membrane 10. At this time, in the indoor unit 1, moisture is released from the hygroscopic medium 5 through the porous plate 2 to the indoor air sucked into the ventilation path 3 by the fan 4.
Humidified air is returned to the room. At this time, in order to improve the indoor humidifying capacity, the hygroscopic medium 5 in the moisture absorbing / releasing section 6 is used.
It is necessary to improve the water supply capacity to the air chamber. For this purpose, the hygroscopic medium 5 may be cooled in the medium chamber 9 or the air supplied to the air chamber 11 may be heated.

[0014]

The air conditioner of the present invention has a simple structure in which the conventional constituent devices are effectively used and only the switching means is added, that is, the dehumidifying operation and the humidifying are performed without causing a significant cost increase. It becomes possible to perform both driving and driving, and therefore, comfort in use can be improved.
