With the above configuration, the operation will be described below. High-humidity air in the room is blown to the hygroscopic element 1 by the blower 102 for processing, and the hygroscopic element 1 absorbs moisture in the air,
Dehumidified air is blown indoors.

As described above, according to the dehumidifying apparatus of the first embodiment of the present invention, when moisture in the air is absorbed by the moisture absorbing element 1, the network structure of the super absorbent polymer physically expands,
Since moisture is retained in the space, there is no generation of heat of adsorption that occurs when ordinary silica gel adsorbs water,
Since the temperature rise is very small at about 1 to 2 ° C., dehumidified air with a small air conditioning load can be supplied indoors. FIG. 2 shows the amount of dehumidification by the water absorbing element 1. The water absorbing element 1 can absorb 1 g of water per 1 g. Therefore, it is possible to control the dehumidifying ability by increasing or decreasing the number of hygroscopic elements.

Will be described with reference to. As shown in the figure, a moisture absorbing element 1 having a corrugated structure 2 made of a highly water-absorbent polymer is provided on the downstream side of the processing blower 102.

The moisture absorbing element 1 is made to absorb moisture, and the dehumidified air is blown into the room. Since the moisture absorption element 1 has the corrugated structure 2, the moisture absorption element 1 has a very low pressure loss, so that a large amount of the moisture absorption element 1 can be used. Therefore, in order to increase the dehumidification performance, it is sufficient to increase the thickness direction of the moisture absorption element 1, and since the contact area of the moisture absorption element 1 with air also increases, the dehumidification performance also improves.

As described above, according to the dehumidifying device of the second embodiment of the present invention, by using the hygroscopic element having a low pressure loss, the dehumidifying performance can be easily improved, and the corrugated structure of the hygroscopic element can be used. Dehumidification performance can be easily changed by changing the number of pitches or the number of cells. Further, by making the shape of the hygroscopic element a corrugated structure, the contact area of high-humidity air can be increased and the dehumidifying ability can be improved.

Next, the third embodiment of the present invention will be described with reference to FIG.

With the above configuration, the operation will be described below. Blower 102 for treating moisture in the indoor high-humidity air
The moisture absorbing element 1 is made to absorb moisture, and the dehumidified air is blown into the room.

By operating for a long time, the moisture absorbing element 1 which is saturated with moisture in the indoor high-humidity air and has deteriorated dehumidifying performance does not absorb moisture any more. However, the drive roller motor 4 rotates the drive roller 3 to wind the blown surface of the hygroscopic element 1 whose dehumidification performance has deteriorated around the drive roller 3 to contain the water that has been wound around the driven roller 5 in advance. Blower 10 for processing the new moisture absorption element 1
It is moved to a position where the high-humidity air sent from 2 comes into contact with it, and the moisture in the high-humidity air is again absorbed by the new hygroscopic element 1.

As described above, according to the dehumidifying apparatus of the third embodiment of the present invention, the dehumidifying element having deteriorated dehumidifying performance is wound up by the driving roller, so that the dehumidifying element having a new life is sufficiently replaced with the dehumidifying element which has reached the end of its life. By sending the moisture absorbing element in the above, the dehumidifying ability can be maintained for a long period of time.

It is also possible to control the life of the dehumidifying ability by adjusting the length of the sheet of the moisture absorbing element.

The material of the hygroscopic element 1 made of a highly water-absorbent polymer is the same as that shown in Example 1 or 2.

With the above configuration, the operation will be described below. The dehumidified air is sent to the room by allowing the moisture absorbing element 1 to absorb the moisture in the high-humidity air in the room by the blower 6 which also serves as the processing and regeneration. When the moisture absorption element 1 becomes saturated with water and the dehumidification performance deteriorates, the air blown from the processing / regeneration and blower 6 is heated by the heater 7 to a temperature of 50 to 70 ° C., and the heated air is kept for 5 to 10 minutes. By sending air to the moisture absorption element 1,
The moisture retained by the moisture absorbing element 1 is desorbed to regenerate the moisture absorbing element 1.

Generally, when a hygroscopic agent such as silica gel is used, 120 to 140 can be used to regenerate the deteriorated silica gel.
It cannot be regenerated unless it is heated at a temperature of ℃ for a long time. However, the hygroscopic element 1 using the super absorbent polymer can be regenerated at a very low temperature in a short time. FIG. 6 shows the moisture absorption performance and the reproduction performance of the moisture absorption element 1. It can be regenerated at a very low temperature of 70 ° C, and has good repeatability, so that dehumidification and regeneration can be used repeatedly.

It is divided into the air passage 8b.

The damper 9 for switching the air passage 8 is a manual type, but may be an electric type. The material of the hygroscopic element 1 made of a highly water-absorbent polymer is the same as that shown in Example 1.

With the above configuration, the operation will be described below. The dehumidified air is sent to the room by allowing the moisture absorbing element 1 to absorb the moisture in the high-humidity air in the room by the blower 6 which also serves as the processing and regeneration. When the moisture absorption element 1 becomes saturated with water and the dehumidification performance deteriorates, the air blown from the processing / regeneration and blower 6 is heated by the heater 7 to a temperature of 50 to 70 ° C., and the heated air is kept for 5 to 10 minutes. By sending air to the moisture absorbing element 1, the moisture absorbing element 1 is regenerated.

The dry air dehumidified by the moisture absorbing element 1 is blown into the room from the air passage 8a by the damper 9 that switches the air passage in the air passage 8. When the dehumidifying performance of the moisture absorption element 1 is deteriorated, the damper 9 switches the air passage, and the humidified air heated by the heater 7 is connected through a duct or the like and discharged to the outside of the room although not shown.

As described above, according to the dehumidifying apparatus of the fifth embodiment of the present invention, the air passages of the dry air during dehumidification and the humidified air during regeneration are divided and the dampers are used to switch the dehumidifying apparatus as it is. And play can be used repeatedly.
If humidified air is exhausted indoors when regenerating, it is useless to dehumidify, so normally it is done outdoors or in the bathroom when regenerating, but if humidified air during regeneration is exhausted outside with ducts etc. In particular, dehumidification and regeneration can be repeated without moving the dehumidifier.

If you want to use it as a humidifier,
It is also possible to switch dry air to the outside and humidified air to the room during regeneration.

Next, the sixth embodiment of the present invention will be described with reference to FIG.
Will be described with reference to. As shown in the figure, in the air passage 8 of the main body provided on the wall surface, the blower 6 for processing and regeneration, the heater 7, the hygroscopic element 1 made of a super absorbent polymer, and the air passage 8 are arranged in order from the upstream side to the outdoor exhaust side and the indoor side. A damper 9 for switching to the blower side is provided.

The damper 9 for switching the air passage 8 is a manual type, but may be an electric type. The material of the hygroscopic element 1 made of a highly water-absorbent polymer is the same as that shown in Example 1.

With the above configuration, the operation will be described below. The dehumidified air is sent to the room by allowing the moisture absorbing element 1 to absorb the moisture in the high-humidity air in the room by the blower 6 which also serves as the processing and regeneration. Further, when the moisture absorption element 1 becomes saturated with water and the dehumidifying performance deteriorates, the air blown from the treatment / regeneration and blower 6 is heated by the heater 7 to a temperature of 50 to 70 ° C., and the heated air is kept for 5 to 10 minutes. By sending air to the moisture absorbing element 1, the moisture absorbing element 1 is regenerated.

As described above, according to the dehumidifying apparatus of the sixth embodiment of the present invention, the contact area of high humidity air can be increased and the dehumidifying ability can be improved by forming the shape of the moisture absorbing element in the corrugated structure, and Since there is no generation of heat of adsorption during moisture absorption, dehumidified air can be supplied indoors without air conditioning load due to temperature rise. In addition, by contacting the air heated by the heater with the moisture absorbing element in a moisture saturated state, the moisture retained in the moisture absorbing element can be desorbed and the moisture absorbing element can be regenerated, and it is provided on the wall surface. Therefore, the regeneration air can be discharged to the outside of the room by switching the damper without using the duct, and at the same time, the room air can be ventilated as a ventilation device.

Next, the seventh embodiment of the present invention will be described with reference to FIG.
Will be described with reference to. As shown in the figure, a moisture absorbing element 1 made of a highly water-absorbent polymer and a heater 7 are alternately laminated and provided on the downstream side of the blower 6 for processing and regeneration.

The material of the hygroscopic element 1 made of a highly water-absorbent polymer is the same as that shown in the first embodiment.

With the above configuration, the operation will be described below. The dehumidified air is sent to the room by allowing the moisture absorbing element 1 to absorb the moisture in the high-humidity air in the room by the blower 6 which also serves as the processing and regeneration. When the moisture absorbing element 1 is saturated with water and the dehumidifying performance is deteriorated, the plurality of moisture absorbing elements 1 which are alternately laminated with the heater 7 and are integrally structured are heated to 50 to 70 ° C. and blown from the blower 6 for processing and regeneration. The moisture retained in the moisture absorbing element 1 is desorbed by air, and the moisture absorbing element 1 is regenerated.

As described above, according to the dehumidifying device of the seventh embodiment of the present invention, when the normal heater is used to regenerate and regenerate the air, 5
Power consumption increases due to the large amount of energy used to heat to 0-70 ° C. However, by forming the heater and the moisture absorbing element in an integrated structure, the heating effect of the moisture absorbing element at the time of reproduction can be improved, and by uniformly heating the moisture absorbing element, the reproduction time and power consumption can be reduced.

Next, the eighth embodiment of the present invention will be described with reference to FIG.
A description will be given with reference to 0. As shown in the figure, the cylindrical hygroscopic element 1 has a corrugated structure 2 and is divided into a processing side and a reproducing side in an air passage. The processing blower 102 is provided in the air passage on the processing side.
Is provided to blow high-humidity air to the moisture absorbing element 1 to absorb moisture and blow it into the room as dry air. A reproduction blower 103 is provided in the reproduction side air passage, and the reproduction blower 103 and the moisture absorbing element 1 are provided.
A heater 7 is provided between the two, and the air blown from the regeneration blower 103 is heated to 50 to 70 ° C. by the heater 7 and blown to the moisture absorption element 1. In addition, the blowing direction is shown as a counter flow on the processing side and the reproducing side, but a parallel flow may be used. A motor 11 is connected to the cylindrical moisture absorbing element 1 by a pulley 10, and the moisture absorbing element 1 is rotated by rotating the motor 11.

The material of the hygroscopic element 1 made of a highly water-absorbent polymer is the same as that shown in Example 1.

With the above configuration, the operation will be described below. The high-humidity air in the room is absorbed by the processing part of the hygroscopic element 1 divided by the air passage in the processing blower 102 and is blown into the room as dry air. In the regenerated portion of the hygroscopic element 1 in which the moisture is saturated and the dehumidifying performance is deteriorated, it is heated by the heater 7 and moisture is desorbed and regenerated. Then, it is exhausted to the outside as humidified air. This moisture absorption element 1 is 10 to 20 rp
Since it is rotating at h, the above-mentioned processing (moisture absorption) and regeneration can be performed continuously and repeatedly.

As described above, according to the dehumidifying device of the eighth embodiment of the present invention, the dehumidification can be continuously performed by rotating the moisture absorbing element. The dehumidified dry air can be used outdoors as well as the humidified air at the time of regeneration to be used as a humidifier.

Next, the ninth embodiment of the present invention will be described with reference to FIG.

The material of the hygroscopic element 1 made of the super absorbent polymer and having the corrugated structure 2 is the same as that shown in the first embodiment.

With the above configuration, its operation will be described below. The high-humidity air in the room is absorbed by the processing part of the hygroscopic element 1 divided into the air passages by the processing blower 102 and is blown into the room as dry air. In the regenerated portion of the hygroscopic element 1 in which the moisture is saturated and the dehumidifying performance is deteriorated, the heater 7 heats the moisture to remove the moisture and regenerate it. Then, the regenerated air containing water passes through the air passage 8 and is recovered in heat by the sensible heat exchange element 12, and is sent again to the regeneration blower 103 through the air passage 8. Further, since the moisture absorbing element 1 rotates at 10 to 20 rph, the above-mentioned processing (moisture absorption) and regeneration can be continuously and repeatedly performed.

As described above, according to the dehumidifying device of the ninth embodiment of the present invention, the dehumidification can be continuously performed by rotating the rotary cylindrical hygroscopic element. By recovering the heat of the regenerated air with the sensible heat exchange element, it is possible to reduce the power consumption consumed for heating and raising the temperature of the heater during regeneration. By regenerating the moisture absorption element in the moisture saturated state by desorption of moisture by heating and reusing the regenerated high humidity air as the regenerated air, the regenerated air is not discharged and the size of the entire apparatus can be reduced. .

Further, since the cylindrical hygroscopic element has a corrugated structure, the contact area of the high-humidity air can be increased to improve the dehumidifying ability, and since the heat of adsorption is not generated during moisture absorption, the temperature rises. The dehumidified air without the air-conditioning load can be continuously supplied to the room.

Furthermore, since the regeneration can be performed at a temperature which is about half the regeneration temperature of silica gel, energy can be saved.
