However, such a conventional humidifier has the following problems.

Since the introduced air to the adsorbent 54 side is not rectified, when the adsorbent 54 is heated by the introduced air when desorbing moisture from the adsorbent 54, the adsorbent 54 has uneven temperature distribution. Occurs. As a result, the adsorbent 54 expands unevenly, and the adsorbent 54 is easily broken by repeatedly operating the desorption and adsorption processes.

Further, since the introduced air is not rectified, uneven distribution of the flow rate of the passing air occurs in the adsorbent 54 during both the adsorption and desorption processes, and a part in the adsorbent 54 that does not function for humidification occurs.

Since the upstream side of the heat source 53 is open to the blower 52 and the air passage 51, there is a risk that the heating wire of the heat source 53 will come into contact with the surroundings due to disconnection or expansion of the heat source 53, causing electric leakage.

According to the present invention, in the adsorption process, the air introduced from the space other than the space to be conditioned is supplied to the adsorbent so that the water contained in the air is adsorbed to the adsorbent to dehumidify in the adsorption process. The generated air is exhausted to a space other than the humidity-controlled space. In the desorption process, the air introduced from the humidity-controlled space is heated by the heat source and passed through the adsorbent to desorb the water adsorbed on the adsorbent. The air thus humidified is discharged to the humidity-controlled space to humidify the inside of the humidity-controlled space.

As shown in FIG. 2, the control unit 11 includes an adsorption control circuit 12, a desorption control circuit 13, and a main control circuit 14.

The adsorption control circuit 12 is composed of a first air passage switching circuit 12a, a first heat source operating circuit 12b, and a first blower operating circuit 12c. Then, the first air passage switching circuit 12a causes the first air passage switching circuit 12a to
The second air passage switching units 6 and 7 are controlled so that the upstream end of the air passage 1 communicates with the air supply port 4 and the downstream end of the air passage 1 communicates with the exhaust port 5, respectively. Further, the first heat source operation circuit 12b is

Further, the first blower operation circuit 12c controls the operation of the blower 9 to allow the adsorbent 8 to pass a predetermined flow rate of air.

The desorption control circuit 13 comprises a second air passage switching circuit 13a, a second heat source operating circuit 13b, and a second blower operating circuit 13c. Then, the second air passage switching circuit 13a, when starting the desorption process,
By controlling the second air passage switching units 6 and 7, the upstream end of the air passage 1 is communicated with the air supply communication port 2 and the downstream end of the air passage 1 is communicated with the air outlet communication port 3, respectively. Also, the second heat source operation circuit 1
3b is to continue the operation of the heat source 10 during the desorption process. Furthermore, the second blower operation circuit 13c controls the operation of the blower 9 to allow a predetermined flow rate of heated air to pass through the adsorbent 8 to desorb moisture from the adsorbent 8.

The main control circuit 14 includes a timer circuit 14a, a driving circuit 14b, a reset circuit 14c and a stopping circuit 14d.

The stop circuit 14d sends a signal to the operation circuit 14b when the operation is stopped, and causes the first and second air path switching units 6 and 7 to communicate the air path 1 with a space other than the humidity-controlled space 1a, and then the heat source 10 The operation of the blower 9 is stopped to make the blower 9 operate strongly, and after the set time has elapsed, the operation is stopped and the air passage 1 is communicated with the humidity controlled space by the first and second air passage switching units 6 and 7. is there.

The operation of the above configuration will be described. That is, when the main power source (not shown) is turned on, the desorption process and the adsorption process described below are alternately repeated to humidify the inside of the humidity-controlled space 1a.

First, in the desorption process, the first air passage switching unit 6 causes the upstream end of the air passage 1 to communicate with the air supply passage 2 by the control signal shown by the chain line in FIG. The portion 7 is located at a position where the downstream end of the air passage 1 communicates with the outlet communication port 3. When the heat source 10 and the blower 9 are activated in this state, the blower 9
Introduces the air in the humidity-controlled space 1a and supplies this air to the heat source 10
After heating by, it is passed through the adsorbent 8. Therefore, the adsorbent 8 is heated to release the adsorbed moisture into the air. The heated introduced air is discharged together with the released moisture from the outlet communication port 3 into the humidity-controlled space 1a to humidify the humidity-controlled space 1a. At this time, a rectifying plate 8a is arranged on the upstream side of the heat source 10 and rectifies the introduced air to rectify the heat source 10
Supply to. Therefore, since the hot air having a uniform temperature distribution can be supplied to the adsorbent 8, the adsorbent 8 can be uniformly heated,
Adsorbed water can be uniformly desorbed from the entire adsorbent 8. Also,
Since the adsorbent 8 can be heated uniformly, expansion that occurs when the adsorbent 8 is heated also occurs in each part on average, and the thermal destruction of the adsorbent 8 can be reduced. Further, since the current plate 8a is made of an insulating material, it is electrically safe even if it is brought close to the heat source 10.

Next, in the adsorption process, the first air passage switching unit 6 causes the air passage 1 to communicate with the air supply port 4 and the second air passage switching unit 7 sends the air by the control signal shown by the solid line in FIG. Exhaust port 5 through path 1
It is in a position to communicate with. In this state, when the heat source 10 is stopped and the blower 9 is operated, the blower 9 moves the humidity controlled space 1a.
Air is introduced from a space other than the above to pass the adsorbent 8.
At this time, the air absorbs moisture contained therein by the adsorbent 8 to become dry air. This dry air is exhausted to a space other than the humidity-controlled space 1a through the exhaust port 5. At this time, the heat source 10
Since the straightening plate 8a is provided on the upstream side of, the introduced air is straightened and then uniformly supplied to the adsorbent 8. Therefore, each part of the adsorbent 8 uniformly adsorbs.

When the operation is stopped during the above-described repeated operation, the heat source 10 is first stopped, and then the first and second air passage switching units 6 and 7 are controlled to set the air passage 1 to a space other than the humidity-controlled space 1a. Of the blower 9, and after the blower 9 has been operated for a set period of time, the blower 9 is stopped, and the first and second air passage switching units 6 and 6 are restarted.
The air passage 1 is communicated with the humidity-controlled space 1a by controlling 7 to stop the operation of the equipment.

When operating as a dehumidifier,
By controlling the second air passage switching units 6 and 7, the air passage 1 communicates with the humidity-controlled space 1a during the adsorption stroke, and the air passage 1 except the humidity-controlled space 1a during the desorption stroke. This can be done by communicating with the space and performing the same operation as above.
