Description

  The present invention relates to a humidifier and an air conditioner equipped with the humidifier.

  Conventionally, an air conditioner having a humidifying function has an adsorption-side space provided with an adsorption-side fan and the adsorption-side space separated from each other, and a desorption-side space provided with a desorption-side fan and a heater. Is formed.

A honeycomb-structured and disk-shaped rotating element (hereinafter referred to as a rotor) carrying a moisture-absorbing material is provided over the adsorption side space and the desorption side space, and takes in outdoor air to the rotor by an adsorption side blower. Then, after adsorbing the moisture contained therein, the rotor is rotated and placed in the detachment side space, the air from the detachment side blower is heated by the heater, and then the rotor is passed through. The moisture of the moisture absorbent was desorbed as water vapor, high-temperature and high-humidity air containing the water vapor was conveyed to the indoor space, and the indoor space was humidified (see, for example, Patent Document 1).
JP 2002-317970 A

  However, in the conventional configuration, the suction side space and the desorption side space need to be partitioned, and a mechanism for rotating the rotor is also required. Since it is necessary to provide each of the blowers, the configuration is complicated, and there is a problem that compactness cannot be realized.

  In addition, since the rotor rotates with respect to the central axis, a disk-shaped configuration is indispensable, and there is a problem that a free configuration cannot be selected for the adsorbent and a compact configuration cannot be realized.

  This invention solves the said subject, and aims at providing a low-cost and compact humidifier and an air conditioner.

  In order to solve the conventional problems, the present invention is directed to a moisture absorbing member that adsorbs moisture in the atmosphere, a suction portion into which the atmosphere flows into the moisture absorbing member, and conveyance that conveys moisture adsorbed by the moisture absorbing member into the room. Switching means for switching the discharge direction of the air after passing through the moisture absorbing member between the transporting part side and the communicating part side, and a communication part for releasing the air after passing through the moisture absorbing member to the atmosphere. The provided humidifier can provide a low-cost and compact humidifier.

  The present invention can provide a low-cost and compact humidifier and air conditioner.

According to a first aspect of the present invention, there is provided a hygroscopic member that adsorbs moisture in the atmosphere, a suction unit through which air flows into the hygroscopic member, a transport unit that transports moisture adsorbed by the hygroscopic member into the room, and the hygroscopic member A humidifying device provided with a switching means for switching the discharge direction of the air after passing through the moisture absorbing member between the conveying unit side and the communicating unit side, A low-cost and compact humidifier can be provided.

  2nd invention is provided with the outdoor heat exchanger and the outdoor fan which allows air to pass through to the said outdoor heat exchanger, The air after passing the moisture absorption member of Claim 1 is air | atmosphere with the attraction | suction force of the said outdoor fan. Use the air conditioner outdoor unit blower with the humidifier as the suction fan required to adsorb moisture in the outdoor air to the moisture absorbing member of the humidifier. Thus, a configuration that can be simplified is made possible.

  As a result, since the outdoor unit blower provided in the outdoor unit of the air conditioner is used as the adsorption side blower for transporting moisture in the outdoor air to the honeycomb moisture absorbent member carrying the moisture absorbent, humidification is performed. There is no need to add a new suction fan to the device. Therefore, it is possible to simplify the configuration, save space, and save resources.

(Embodiment 1)
FIG. 1 is a schematic view of an air conditioner including a humidifier according to a first embodiment of the present invention.

  In FIG. 1, the air conditioner includes an outdoor unit 2 that includes a humidifying device 1 that is disposed outdoors, and an indoor unit 3 that is disposed indoors. The indoor unit 3 is provided with an indoor heat exchanger 4 and an indoor fan (not shown). Further, the humidifier 1 and the indoor unit 3 are connected by a humidified air conveying pipe 5 to send humidified air to the indoor space. The outdoor unit 2 is provided with a compressor 6, an outdoor heat exchanger 7, an expansion valve 8, and a four-way valve 9, and the outdoor fan 10 is an outdoor fan installation space configured by the outdoor heat exchanger 7 and the outdoor fan 10. 11 is arranged. The compressor 6, the four-way valve 9, the indoor heat exchanger 4, the expansion valve 8, and the outdoor heat exchanger 7 are connected by a refrigerant pipe 12 to form a refrigeration cycle in which refrigerant circulates as is well known. Switching between cooling operation and heating operation is performed. During the heating operation, the high-temperature gas refrigerant discharged from the compressor 6 is sent to the indoor heat exchanger 4 via the four-way valve 9, and the condensed high-pressure liquid refrigerant is decompressed via the expansion valve 8 to be the outdoor heat exchanger. 7 and returned to the compressor 6 through the four-way valve 9.

  The humidifying device 1 is provided with a stationary moisture absorbing member 13, a desorption side space 14 above the moisture absorbing member 13, a heater 15 as a heating means at the lower portion, and an inlet 16 for sucking outdoor air. ing. Further, the desorption side space 14 is provided with a desorption side blower 17 for sucking high-temperature and high-humidity air and transporting it to the indoor space. It communicates with the suction side space 19. Moreover, between the adsorption | suction side space 19 and the outdoor fan installation space 11 of the said outdoor unit 2, the damper 20 which is the switching means which partitions off those spaces and can be opened and closed as needed is provided.

About the humidification apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
In the humidifier 1, the damper 20 is opened without energizing the heater 15 while the outdoor fan 10 is rotating during the adsorption operation.

  At that time, the outdoor fan installation space 11 has a negative pressure with respect to the atmospheric pressure, so outdoor air is taken in from the suction port 16 in the previous period, and the adsorption member 13, the desorption side space 14, the communication port 18, and the adsorption side space. 19, sequentially passes through the damper 20, reaches the outdoor fan installation space 11, and is discharged into the atmosphere by the outdoor fan 10 together with the air sucked from the outdoor heat exchanger 7. At this time, since the moisture absorbing member 13 carries a moisture absorbing material such as zeolite, moisture in the air taken in is trapped in the moisture absorbing member 13.

Further, during the detachment operation, the damper 20 is closed, the heater 15 is energized, and the detachment side blower 17 is operated. At this time, the air taken in from the suction port 16 is heated by the heater 15 and passes through the moisture absorbing member 13 in a state of high temperature, and the adsorption member 13 is heated and trapped in the adsorption member 13. Is desorbed and becomes high-temperature and high-humidity air and reaches the desorption-side space 14, and the air is sent by the desorption-side blower 17 into the transfer pipe 5 as a transfer unit and discharged into the indoor space. By alternately performing the adsorption operation and the desorption operation, a predetermined amount of humidified air is sent to the indoor space to humidify the indoor space.

  As described above, in the present embodiment, the outdoor fan installation space 11 and the suction side space 19 are opened and closed by the damper 20 as necessary, and the outdoor fan is used for the outdoor fan installation space 11 during the suction operation. By allowing outdoor air to be taken in, the simplified configuration of the humidifier 1 can be achieved without providing a dedicated suction fan.
