DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the dehumidifying / drying device according to the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a bathroom and 2 is a bathtub. In recent years, the bathroom 1 is made to function as a dehumidifying / drying room to dry the clothes 3. In addition,
Reference numeral 4 is a gallery.

On the ceiling of the bathroom 1, as will be described later,
The suction port 5 and the air outlet 7 are provided, and the dehumidifying / drying device 100 is connected thereto. The dehumidifying / drying device 100 is provided with a dehumidifying element 11, and a suction line 13 connected to the suction port 5 and a blowout line 15 connected to the blowout port 7 are connected to the dehumidifying element 11.
A blower 17 is connected to the.

According to this, the moistened humid air in the bathroom 1 sucked through the suction port 5 is dehumidified by the dehumidifying element 11, and then becomes circulating air through the blower 17 to form a blowout port. It is returned from 7 to the bathroom 1.

Further, the dehumidifying element 11 is provided with a regeneration line 19 for regenerating the dehumidifying element 11.

One end of the regeneration line 19 is connected to an inlet 21 for regeneration air (for example, provided in a washroom), and the other end is connected to an outlet 23. According to this, when the regeneration of the dehumidifying element 11 is requested, the blower 25 is driven, and the air taken in from the outlet 21 is heated by the heater 27 and is dehumidified so as to be orthogonal to the above-mentioned circulating air. The air is sent to the element 11, and after the dehumidifying element 11 is regenerated, it becomes humid air and is discharged from the discharge port 23.

Since the air discharged from the discharge port 23 has a relatively high temperature and high humidity, it contains a large amount of water (high absolute humidity). Compared to the hot air ventilation drying method, the efficiency of moisture removal is higher.
Therefore, according to this, the energy required for heating the inside of the bathroom 1 is small, and more efficient operation than the warm air ventilation drying method becomes possible.

In the above-mentioned structure, according to this embodiment, the dehumidifying element 11 has the ceramic honeycomb laminated body. And, in this ceramic honeycomb laminate,
For example, a metal silicate gel in which a plurality of metals such as cobalt, iron and manganese are combined with silica gel is polymerized.

The dehumidifying element 11 adjusts the shapes of the micropores and meripores involved in the adsorption of moisture, and by incorporating the metal in the form of metal chloride into the ceramics honeycomb laminate, moisture adsorption is achieved. The amount is increasing.

Further, many hydroxyl groups are fixed in the pores,
The hydrophilicity is increased, and thus the water adsorption and desorption properties are improved.

This makes the device compact,
The amount of heat energy for regeneration is correspondingly reduced, and an efficient device is provided. Needless to say, this type of dryer is not limited to a bathroom dryer, but can be used for various purposes such as a push-in dryer, a futon dryer, a room dehumidifier, and a dryer.

FIG. 2 shows another embodiment.

According to this, the dehumidifying element 31 is the motor 3
It is a rotary type driven by 3. In the case of this rotary type,
Regeneration air is fed in the direction opposite to the circulating air.

FIG. 3 shows another embodiment.

In this embodiment, a heating device 35 for heating the circulating air is provided on the secondary side of the dehumidifying element 11. According to this, the air dehumidified through the dehumidifying element 11 is heated by the heating device 35 and then heated in the bathroom 1.
Returned inside.

In this example, the heating device 35 is a hot water heat exchanger, to which a hot water generator (eg boiler) 37 is connected. The heating device 35 may be an electric heater. Reference numeral 39 is a control valve for controlling the flow rate of hot water, and 40 is a controller.

According to this, the dehumidified air is once heated by the heating device 35 and then returned to the inside of the bathroom 1, so that the temperature inside the bathroom 1 is maintained at a constant temperature and the effect of blowing off steam is promoted. Therefore, unlike the conventional one, it does not take a long time to dry the clothes 3, and the drying efficiency is improved.

By using the heating device 35, the bathroom 1
It goes without saying that the heating operation inside can be performed.

As yet another embodiment, electric dampers 51 and 53 are provided in front of and behind the blower 25 in the regeneration line 19.

The electric damper 51 is for switching the intake port for the regeneration air sent to the regeneration line 19. When it is switched to one direction, the air in the bathroom 1 is taken in as regeneration air, and when it is switched to the other direction, the air in the rest, for example, the washroom, is taken in as regeneration air.

The electric damper 53 sends the regeneration air taken into the regeneration line 19 to the dehumidifying element 11 or bypasses it. When it is bypassed, the taken-in air is transferred along the ventilation line 20 and naturally discharged to the outside through the discharge port 23.

The ventilation line 20 including the electric damper 53 and bypassing the dehumidifying element 11 constitutes a ventilation device.

As an example of how to use the ventilation line 20, immediately after taking a bath, the amount of water in the bathroom 1 is large, and in such a case, before the dehumidifying / drying operation is performed using the dehumidifying element 11. In addition, for example, the ventilation operation using the ventilation line 20 is performed within the time set by the timer. By doing so, the water content immediately after bathing is removed, so that the subsequent dehumidifying and drying operations can be efficiently performed.

At that time, fresh air outside the room enters the bathroom 1 from the louver 4 provided at the bottom of the bathroom 1.

In FIG. 4, the dehumidifying element 31 is replaced with a rotary type driven by a motor 33. According to this, the regeneration air is fed in the direction opposite to the circulating air. Other configurations are the same as those in FIG.

FIG. 5 shows still another embodiment.

According to this, the temperature sensor 41 is provided at the inlet of the dehumidifying / drying device (the device inlet of the circulating air). The temperature sensor 41 is connected to the controller 40, and the controller 40 controls the heating amount of the heating device 35 according to the temperature detected by the temperature sensor 41.

Incidentally, as shown in FIG. 4 corresponding to FIG. 3, it is possible to change the dehumidifying element 31 to a motor-driven rotary type.

FIG. 6 shows another embodiment.

According to this, the temperature sensor 55 and the humidity sensor 57 are provided at the inlet of the dehumidifying / drying device (the device inlet for circulating air), and the humidity for detecting the humidity outside the bathroom 1 is provided outside the bathroom 1. Sensors 59 are provided, which are connected to the controller 40. This controller 40 is shown in FIG.
In accordance with the processing flow shown in, the hot water generator 37 and the control valve 39
Control.

Referring to FIG. 7, when the operation is started (S1),
It is determined whether the humidity inside the bathroom 1 is higher than the outside humidity (S2). If the humidity is larger than the outside humidity, only the ventilation operation is performed (S3), and then the heating operation in the bathroom 1 is performed (S).
4).

In the case of the operation of only ventilation, it is economical because only the power of the blower 25 is required, and a considerable amount of water can be discharged even in this operation. Is extremely effective as

When the determination in S2 is small, S3 is skipped and the heating operation in the bathroom 1 is immediately performed (S).
4). During the heating operation, the inside of the bathroom 1 (laundry, walls, tiles, tile joints) is heated / maintained to promote evaporation of water from the material to be dried. At this time, the heating device 35 is controlled according to the temperature detected by the temperature sensor 41,
The preset temperature is maintained.

Then, it is judged whether the temperature in the bathroom 1 is higher than a predetermined set temperature (S5). If the temperature is high, the above temperature maintaining operation in the bathroom 1 is started (S6). It returns to the determination step S5 again.

After S6, it is determined whether the set time has passed (S7), and if so, the dehumidifying operation is performed (S).
8). This is because when the set time has elapsed, the humidity inside the bathroom 1 rises due to the evaporation of water from the material to be dried. If the set time has not elapsed, the process returns to the determination step S7 again. After the dehumidifying operation, it is determined whether the set humidity is exceeded (S9),
If it exceeds, the control is terminated after counting the set number of cycles (S10), and if not exceeded, the dehumidifying operation is returned to (S8).

If the set number of cycles is not counted, the process returns to S4.

According to this embodiment, the energy saving effect becomes particularly remarkable in the region where the drying progresses to some extent and the amount of water vaporized per unit time gradually decreases.
Therefore, in the operation immediately after the start of the drying operation, while the heating operation by the heating device 35 is being performed, the operation for dehumidifying using the dehumidifying element 11 (heating and dehumidifying simultaneous operation) may be performed. This is done between S3 and S4.

When considering the drying in the bathroom 1,
(1) When only resin wall surfaces are dried like a unit bath, (2) When not only the tile surface like tiled bathroom 1 but also tile joints are dried (3) A case such as the case where even the clothes 3 that have been dried is also conceivable.

In the case of (1), the drying can be performed relatively easily, but in the cases of (2) and (3), the drying time becomes long. According to this, depending on the purpose of drying, S5, S7, S9, S
By changing the set times A, B, C, and D of 10, respectively, extremely effective control can be performed in each case.

It should be noted that FIG. 4 corresponding to FIG. 3 also in this embodiment.
As described above, the dehumidifying element 31 can be changed to a motor-driven rotary type.

[0058]

As is apparent from the above description, according to the present invention, the dehumidifying element includes a ceramic honeycomb laminated body, and this ceramic honeycomb laminated body includes silica gel and a plurality of cobalt, iron, manganese, or the like. Since the metal silicate gel in which the metals are combined is polymerized, the water adsorption and desorption properties are improved, the energy required for regeneration is suppressed to a small level, and the apparatus can be made compact and energy saving can be achieved.
