Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidity controller using a hygroscopic material.

[0002]

2. Description of the Related Art A conventional dehumidifier has a dedicated device for dehumidifying only and a humidifier for humidifying only. The respective units are controlled to adjust the humidity of a room.

[0003]

SUMMARY OF THE INVENTION One machine can be a humidifier or a dehumidifier, and can automatically select a humidification operation or a dehumidification operation to adjust a desired humidity set value. It is a thing.

[0004]

[Means for Solving the Problems] A rotor made of a hygroscopic material formed by cylindrically forming a hygroscopic material having a property of adsorbing moisture in air is rotated about its axis, and air is passed in the axial direction of the rotor. Is provided with a passage that divides the passage surface into two, one passage being a circulation path for indoor air to be subjected to humidity control, and the other passage being a circulation path for outdoor air,

An air blower is provided in each passage and an air heating heater is arranged on the upstream side of the hygroscopic material, and the indoor air and the outdoor air are continuously sucked simultaneously at the same time. The indoor air is returned to the room and the outdoor air is returned to the room after passing through the material.

When dehumidifying the interior of the room, the heaters arranged in the indoor air circulation path are not energized, and the heaters arranged in the outdoor air circulation path are energized so that a high-temperature air flow is obtained. The rotor of the hygroscopic material that has absorbed the moisture of the

Since the outdoor air is heated to a high temperature by the heater and passes through the rotor made of a hygroscopic material, the moisture in the indoor air adsorbed by the moisture absorbing rotor is dehumidified (released) and returned to the outside again. In this way, the moisture in the room is once adsorbed to the rotor of the hygroscopic material and discharged to the outside of the room to dehumidify the room.

In the case of humidifying, contrary to the case of dehumidifying, the heater arranged in the indoor air circulation path is energized,
Do not energize the heater placed in the outdoor air circulation path, and move the rotor of the moisture absorbent that has absorbed moisture from the outdoor air to the indoor air passage to move the indoor air to a high temperature by the heater to absorb moisture. Since it passes through the material, the moisture in the outdoor air adsorbed to the rotor of the hygroscopic material is dehumidified (released) and returned to the room again.

In this way, the outdoor moisture is once adsorbed to the rotor of the hygroscopic material and taken into the room to humidify the room. Since the rotor of the hygroscopic material continuously rotates in one direction, moisture absorption at room temperature and dehumidification at high temperature are periodically repeated.

The present invention will be described with reference to the drawings. FIG. 1 is a view showing an embodiment of the present invention, and FIG. 2 is a front view a side view b of the humidity controller. FIG. 1 is a horizontal cross-sectional view of the humidity controller 10 attached to the indoor side of the indoor and outdoor partition walls 14.

A motor 4a for circulating the indoor air is attached to a partition plate 3 which divides a passage for circulating the indoor air in the direction of arrow A and a passage for circulating the outdoor air in the direction of arrow B, with a screw (not shown), and a blower blade. 5a is attached to the motor 4a.

Further, a motor 4b for circulating the outdoor air is similarly attached to the partition plate 3, and a blower blade 5b is fitted and attached to the shaft thereof. When the power switch 12 is turned on from the power cord 11 to energize, the blower motors 4a and 4b start to rotate, and the blades 5a and 5b rotate, and at the same time, the motor for driving the rotor 7 of the hygroscopic material shown in FIGS. 18 also starts to rotate, and the rotor 7 made of a hygroscopic material also starts to rotate via the pulley 20 and the transmission belt 8.

The both ends of the rotor 7 made of the moisture absorbing material are the support plates 1
The support plates 15 and 15 'are rotated by being pivotally supported by the protrusions 15a and 15a' of the reference numerals 5 and 15 ', and the support plates 15 and 15' have two semi-circular vents 15.
b, 15b 'and 15c, 15c' are open for ventilation in the axial direction. The support plates 15 and 15 'are fastened at four places with spacers 17a to d, which are slightly longer than the length of the rotor 7 made of a moisture absorbent material, and screws 16a to d, 16a' to d ', which are flat heads. The support plates 15 and 15 'are assembled so that they can rotate around the projections 15a and 15a' integrated with the support plates 15 and 15 '.

Appropriate tension is applied to the transmission belt 8 by the roller 21, and the rotation is transmitted to the moisture absorbent rotor 7 by frictional force. Semicircular ventilation holes 15b of the support plates 15 and 15 '
The radius of the arc portion of the windows of ~ c 'is made smaller than the radius of the rotor 7 made of a hygroscopic material to secure the overlap margin and prevent leakage of air passing through the rotor 7 made of a hygroscopic material. A space is provided by axially dividing the hygroscopic material into one of the two semi-circular windows so that the indoor air passes and the other through the outdoor air.

The air in the room is sucked in through the suction port X, passes through the heater 6a fixed by the fixing portion 9a between the front panel 2 and the partition plate 3, passes through the slowly rotating rotor 7 of the hygroscopic material, and is discharged. It is returned to the room from mouth Y again. When dehumidifying the room, the heater 6a is not energized, and when humidifying, the energization is controlled so that the heated air passes through the rotor 7 which is a hygroscopic material.

The outdoor air is sucked in through the suction port S, passes through the heater 6b fixed by the fixing portion 9b between the back panel 1 and the partition plate 3, and passes through the slowly rotating rotor 7 of hygroscopic material and is discharged. It is returned to the outside from the mouth T again. When dehumidifying the interior of the room, the heater 6b controls energization, and the heated air passes through the rotor 7, which is a hygroscopic material, and does not energize when humidifying.

When the heaters 6a and 6b are not energized, air at room temperature passes, so that moisture is adsorbed from the air, and when hot heated air passes, the moisture is desorbed. Therefore, when it is necessary to dehumidify the room, the heater 6a is not energized,
When it is necessary to energize 6b and conversely humidify it, the heater 6a is energized and 6b is controlled so as not to be energized, and the adjustment knob 13 is automatically adjusted to the desired humidity.

If a humidity sensor (not shown) is attached to the suction port X, the inside of the room can be controlled to a constant humidity, and if it is attached to the suction port S, it is installed outside the partition wall 14 between the room and the outside to control the room to a constant humidity. You can do it.
Therefore, even if a humidity sensor is attached to both of the suction ports X and S and the humidity controller is attached to either side of the partition wall, the indoor position can be controlled to a constant humidity by switching the attachment position changeover switch 19. You can do it.

Further, by providing three switching operation functions of dehumidifying operation, humidifying operation, and automatic operation, it can be used as a dehumidifier alone or as a humidifier alone, and as described above, either one is automatically required. It becomes possible to control the inside of the room to a constant humidity according to the selection.

[0020]

As described above, according to the present invention, 1
Since it can be used as a dehumidifier on a stand or as a humidifier, and because the moisture absorbent rotor is continuously and slowly rotated, it is possible to perform a stable dehumidifying operation and a humidifying operation continuously. The control accuracy of indoor humidity can be improved.
