Description

Detailed Description of the Invention

[0001]

The present invention relates to dehumidification using a hygroscopic material,
The present invention relates to a device for both drying and heating, and is capable of drying laundry by using, for example, a bathroom.

[0002]

2. Description of the Related Art Conventionally, when laundry is dried in the bathroom, warm air is circulated in the bathroom for a certain period of time with a device having both a heating function and an exhaust function, and then the exhaust air is discharged for a certain period of time. By repeating the above operation, that is, applying warm air to the laundry, the moisture evaporates and the humidity in the bathroom increases, and if it becomes too high, the drying efficiency deteriorates. After lowering it, it was done by repeating the operation of blowing warm air again to dry it.
However, when circulating hot air, heat cannot escape unless the room is closed and the effect cannot be expected.However, in the case of exhaust air, if the air is closed, the room will become negative pressure. Because of this, most of the exhaust blowers simply run idle and the exhaust capacity becomes extremely poor, so the drying efficiency is low. In addition, since a device that merely sends hot air and dries does not have a dehumidifying function that keeps the humidity in a comfortable state, it is necessary to separately prepare a dehumidifier when dehumidifying the room.

[0003]

Instead of discharging the moisture of the laundry in the room, that is, the evaporated moisture, to the outside together with the indoor air, the room is sealed and only the moisture or the humidity of the laundry is discharged to the outside. It is possible to dehumidify indoors where molds easily grow because it is compact and has a high drying capacity. As a measure to raise blood pressure when taking a bath, one unit is provided with those functions so that the room can be heated before taking a bath.

[0004]

A hygroscopic material having a property of adsorbing moisture in the air is formed in a cylindrical shape, and a rotor of the hygroscopic material provided with a rotation shaft is rotated about the axis to move air in the axial direction. Through which the air passage surface is divided into two to provide a plurality of passages, one passage being an indoor air circulation passage, the other passage being an outdoor air circulation passage, and a blower and an air passage to each passage. A heater for heating is installed, and the indoor air and the outdoor air are sucked in, and the outdoor air passes through the heater first and then passes through the hygroscopic material slowly rotated by the rotating means such as a motor and returns it to the outside again. After passing through the heater, the heater is passed through and then returned to the room.

When dehumidifying the room, the heater arranged in the indoor air circulation path is not energized, and the heater arranged in the outdoor air circulation path is energized so that a high-temperature air flow is obtained. When the rotor of the hygroscopic material that has adsorbed the humidity of the air rotates and moves to the passage of the outdoor air, the outdoor air is heated to a high temperature by the heater and passes through the rotor of the hygroscopic material. Dehumidify (release moisture) and return it to the outside.
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.

When the laundry is dried in the room and dried, the heater disposed in the indoor air circulation path is also energized while the dehumidifying operation is performed to dry the laundry with warm air. Keep the humidity low and the drying efficiency high. When heating the room, a blower that circulates the room air is operated to take in the room air, and a heater arranged in the room air circulation path is energized to return warm air to the room again. In this case, the blower that circulates the outdoor air, the heater in the outdoor air circulation path, and the rotor of the hygroscopic material are in a stopped state.

[0007]

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 a combined dehumidifying, drying and heating device. FIG. 1 is a cross-sectional view showing a state in which the dual function device 10 is attached to a partition wall 14 inside and outside the room.

A motor 4a for circulating indoor air is attached with a screw (not shown) 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, 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 dehumidifying operation is designated on the operation panel (not shown), the blower motors 4a and 4b start to rotate and the blades 5a and 5b rotate, and at the same time, the motor 18 for driving the rotor 7 of the hygroscopic material shown in FIGS. Starting to rotate 2
0, the rotor 7 made of a hygroscopic material also starts to rotate via the transmission belt 8.

Both ends of the rotor 7 made of the moisture absorbent material are supported by the support plate 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 passes through the slowly rotating rotor 7 made of a hygroscopic material, passes through the heater 6a arranged in front of the discharge port Y, and is returned to the room again. When dehumidifying the room, the heater 6a is not energized. The outdoor air is sucked from 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, passes through the slowly rotating rotor 7 of the hygroscopic material, and passes through the discharge port T. It is returned to the outside again. When dehumidifying the room, the heater 6b is energized to control the heated air.
The absorbent 7 passes through the rotor 7. Next, when the drying operation is designated on the operation panel (not shown), the heater 6a arranged in the indoor air circulation path is also energized while the above-described dehumidifying operation is performed.
When the heating operation is designated on the operation panel, the motor 6b for circulating the outdoor air and the blower 5b are stopped and the heater 6 is operated.
b is not energized, and the motor 4a for circulating the indoor air and the blower 5a are rotated while the drive motor 18 of the moisture absorbent rotor is also stopped to suck in the indoor air and pass through the moisture absorbent rotor 7 which is stopped. After passing through the heater 6a whose energization is controlled, it becomes hot air and is returned to the room again.

Further, if the heater 6a is not energized, it can be used as a circulator for circulating the air in the room, so that this operation mode can be given to the operation panel. In addition, since it is easy to understand that the heater 6a is not energized during the drying operation, and even if the drying operation is performed in the dehumidifying operation itself, it is easy to understand that it has the drying ability, this may be done. Also, during this drying operation, the heater 6a
It is easily conceivable to control the temperature of the room and humidity by a preset program to maintain the drying capacity and prevent the temperature of the room from becoming too high.

[0014]

As described above, according to the present invention, 1
It can be used for dehumidifying, drying, and heating on the stand, and can be used for drying laundry, for example, in the bathroom at home, and since it has a higher drying capacity than conventional ones, it should be miniaturized. Is possible. In addition, since the bathroom tends to be damp, there is a lot of mold damage, and since dehumidification can be done against this, mold growth can be prevented. Furthermore, when a winter elderly person takes a bath, the temperature in the bathroom is low before taking a bath, and blood pressure rises temporarily, which has a bad effect on health. This also makes it possible to take a comfortable bath by heating it in advance before taking a bath. Things are possible.
