Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a dehumidifying method for making a room a dry atmosphere by using a static dehumidifier and a technical field of a dehumidifying device incorporating a static dehumidifier.

[0002]

2. Description of the Related Art As this type of apparatus, for example, a drying apparatus is known which makes a bathroom a dry atmosphere so that it can be used as a drying room for clothes and the like. Can be roughly classified. The former uses, for example, a dehumidifying rotor capable of reversibly absorbing and releasing moisture as a dehumidifier as disclosed in Japanese Utility Model Laid-Open No. 6-10782 and Japanese Patent Laid-Open No. 7-180956. . The latter is disclosed in, for example, JP-A-5-164359 and JP-A-6-sho.
JP-A-3-287532 and JP-A-1-287532
As disclosed in the publication, a static dehumidifier capable of reversibly absorbing and releasing moisture is used.

Although a drying device using a dehumidifying rotor is capable of continuous dehumidifying treatment, it requires a dynamic seal at a portion for sending an air flow to a rotating dehumidifying rotor, which complicates the structure.
Although the device becomes large in size, the static dehumidifier has a structure in which the dehumidifier does not move, and therefore a dynamic seal is not required and a simple structure can be adopted, and the manufacturing is relatively easy.

The dehumidifier itself, both of the rotary type and the static type, may be formed by corrugating a corrugated material or a honeycomb material, to which a hygroscopic agent such as silica gel is attached, and forming it into a cylindrical shape, or by stacking it into a hexahedral block. doing. By passing the processing air through the passage of the dehumidifier having such a configuration, dehumidified and dry air is obtained. Also, if heated air is passed through the passage of the dehumidifier that has absorbed moisture, the dehumidifier is dehumidified, regenerated, and exhibits the dehumidification function again.

The dehumidification technique using a static dehumidifier disclosed in Japanese Patent Laid-Open No. 63-287532 discloses a dehumidification process in which room air is passed through a static dehumidifier and then returned to the room, and indoor or outdoor. The air is heated and then passed through a dehumidifier, and the regeneration process of exhausting the air to the outside is alternately repeated. As shown in FIG. 13, in a drying device to which this technique is applied, a static type dehumidifier 101 is provided in a ventilation passage 102 that circulates indoor air so that ventilation is possible, and a damper 103 provided in the ventilation passage 102 is switched. It is configured to alternately repeat dehumidification and regeneration (ventilation). An air flow in the same direction flows into the dehumidifier 101 during the dehumidification process and the regeneration process, and a heater 104 that heats the air flow during the regeneration process is provided on the upstream side of the dehumidifier 101.

[0006]

The drying device using the conventional static dehumidifier 101 as described above is a dehumidifier 101.
The dehumidification function of itself was not fully brought out, and the performance was dissatisfied. That is, the moisture absorption capacity of this type of dehumidifier 101 is influenced by the temperature, and the lower the temperature, the higher the moisture absorption capacity. However, the directions of the air streams flowing through the dehumidifier 101 in the dehumidification process and the regeneration process are the same. Therefore, when shifting from the regeneration process to the dehumidification process, the air flow always flows from the side that has become hot during the regeneration process, and the characteristics of the dehumidifier 101 cannot be fully utilized.

[0007] Further, although many of the drying devices have a structure for performing a regeneration process as mentioned in the section of the prior art to be able to perform ventilation, the above-mentioned conventional static type drying device is Since the indoor air is discharged through the dehumidifier 101 even in the ventilation operation, only a small amount of air can be ventilated, and it is not possible to deal with the case where a large amount of air is required for ventilation.

The present invention has been made in order to solve the above-mentioned conventional problems. The problem is to use a static dehumidifier that can bring out the dehumidifying function of the static dehumidifier better. Is to obtain a dehumidifying method, and to obtain a static dehumidifier utilizing the dehumidifying method.
It is to improve the function of the static dehumidifier, and to obtain a simple static dehumidifier with a structure that can perform regeneration and heating of the dehumidifier with a single heater, and it is also possible to ventilate a large air volume. Another object is to obtain a static dehumidifier, and to obtain a static dehumidifier that can accurately switch between dehumidification and regeneration.

When the exhaust passage is closed by the damper and the air flow is such that the heater side is on the downstream side, the air dehumidified by the dehumidifier can be supplied into the room to create a dry atmosphere in the room. If the heater is operated in this state, the warm air can bring the room into a heating atmosphere. Also, if the damper closes the open end of the ventilation passage and opens the exhaust passage to operate the heater, and the heater side is set to the upstream air flow, the dehumidifier can be regenerated by the heated air flow. The air supplied to the air is exhausted from the exhaust passage, so that the room is also ventilated.

Embodiments of the present invention will now be described with reference to the drawings. First Embodiment of the Invention The dehumidifying method of the first embodiment is
The dehumidifier 1 having a reversible moisture absorption / desorption function and having the structure shown in FIG. 1 is used to dehumidify the room as shown in FIG. Dehumidifier 1 applied to this dehumidification method
As shown in FIG. 1, a corrugated structure material or a honeycomb structure material in which a hygroscopic agent such as silica gel is bonded to an inorganic fiber such as ceramics by using a polymerization reaction is laminated to form a large number of linear air-permeable members through which treated air is passed. The passages 2 are formed in a rectangular parallelepiped shape or a cubic shape in which they are distributed over the whole. Each passage 2 is parallel and all of its open ends are open to two opposite surfaces of the dehumidifier 1.

As shown in FIG. 2, the dehumidifier 1 having the above-mentioned structure is provided in the ventilation passage 3 so that each passage 2 constitutes a part of the ventilation passage 3 to form a static dehumidifier 1. . The static dehumidifier 1 is made to alternately repeat the dehumidification process and the regeneration process. The dehumidification process is a process in which the air in the room is sucked in by the blower 4, passed through the dehumidifier 1 in the ventilation passage 3, dehumidified, and returned to the room. The regeneration process is a process in which the indoor air sucked by the blower 4 is heated to about 140 ° C. by the heater 5 as a heating means provided in the air passage 3 and then passed through the dehumidifier 1 to be discharged outside the room. The feature of the dehumidifying method of the first embodiment is that the air passing through the room to the dehumidifier 1 in the dehumidifying process and the regenerating process is performed in opposite directions.

The moisture absorption capacity of this type of dehumidifier 1 is affected by temperature, and the lower the temperature, the higher the moisture absorption capacity. However, the direction of the airflow flowing through the dehumidifier 1 in the dehumidification process and the regeneration process is the same. Then, when shifting from the regeneration process to the dehumidification process, the air flow in the dehumidification process always flows in from the side that has become hot during the regeneration process, and the above-mentioned characteristics of the dehumidifier cannot be utilized. On the other hand, if the direction of passage of the indoor air to the dehumidifier 1 in the dehumidifying step and the regeneration step is opposite, that is, counterflow, the temperature of the inflow side of the dehumidifier 1 in the dehumidification step after the regeneration step Temperature can be prevented, the dehumidifying performance of the dehumidifier 1 can be brought out, and the energy efficiency can be improved.

The time of the dehumidifying process is set to be slightly shorter than the time of the regenerating process, and the reversal of the direction of the air flow is achieved by switching the air passage by opening / closing the damper 6, or by switching the forward / reverse switching of the axial blower with the damper. It should be done by. By setting a temporal cushion, that is, a short cooling time at the time of transition from the regeneration process to the dehumidification process, the dehumidifier 1 that has undergone the regeneration process
The temperature of the inflow side in the dehumidification process can be further lowered, and the dehumidification function of the dehumidifier 1 can be further brought out.

According to the dehumidifying method of the first embodiment, not only the functionality of the dehumidifier 1 can be enhanced, but also the heater 5 used in the regeneration process can be used for heating. That is, by forming an air flow in the same direction as in the dehumidifying process and operating the heating means, heating by blowing warm air into the room is realized. At this time, since the heater 5 used in the regeneration process is located on the downstream side of the dehumidifier 1, the heated air flow does not pass through the dehumidifier 1, so that the dehumidifier 1 does not take heat and its life is reduced. Does not shorten the
For the reasons described above, the dehumidification process can be smoothly performed.

Each of the embodiments described below relates to a static dehumidifier utilizing the dehumidification method using the static dehumidifier 1 shown in the first embodiment.

Embodiment 2 of the Invention FIG. 3 is a cross-sectional configuration diagram showing the static dehumidifier of the second embodiment, and FIG.
Is also a vertical cross-sectional configuration diagram. This static dehumidifier
The static type dehumidifier 1 shown in the first embodiment can be ventilated by the passage 2 in the middle of the ventilation passage 9 in which the indoor air outlet 7 and the indoor air inlet 8 are opened as the outlet end and the inlet end, respectively. Intervened. The ventilation passage 9 is a main body casing 11 attached to the ceiling or the like of a room to be dehumidified such as a bathroom 10.
The indoor suction port 8 and the indoor air outlet 7 are defined in the interior of the main casing 11 and are separated from each other and open toward the room. The indoor suction port 8 and the indoor air outlet 7 are provided with a grill, and a filter 12 is mounted inside the grill of the indoor suction port 8.

From the dehumidifier 1 in the ventilation passage 9 to the indoor suction port 8
On the side, a blower 13 is built in the ventilation passage 9 to form an air flow of indoor air from the indoor suction port 8 through each passage 2 of the dehumidifier 1 toward the indoor air outlet 7. Further, a heater 14 for raising the temperature of the air passing through the part is installed in the ventilation passage 9 on the indoor outlet 7 side of the dehumidifier 1 so as to traverse the ventilation passage 9. Between the dehumidifier 1 and the blower 13 in the ventilation passage 9, there is connected an exhaust passage 16 which can be opened and closed by an electric damper 15 and has one end communicating with the outside. This exhaust passage 16
The ventilation passage 9 is provided between the blower 13 and the connecting portion with the ventilation passage 9 of
An electric damper 17 that opens and closes the relevant part is provided.
In the vicinity of the dehumidifier 1, an air passage 9 composed of each passage 2 is provided.
A regeneration passage 18 is formed in parallel with the above portion. One end of this regeneration passage 18 is connected to the ventilation passage 9 near the blower outlet of the blower 13, and the other end is connected to the ventilation passage 9 between the indoor blower outlet 7 and the heater 14. The electric damper 17 that opens and closes the ventilation passage 9 is configured to close the regeneration passage 18 by opening the ventilation passage 9 and open the regeneration passage 18 by closing the ventilation passage 9.

A uniform plate 19 made of a thin plate made of metal or the like having a large number of small holes substantially uniformly distributed between the heater 14 and one surface of the passage 2 of the dehumidifier 1 facing the opening end of the passage 2.
Is attached so as to cross the ventilation passage 9 of the relevant portion.
Further, first and second temperature sensors 20 and 21 are incorporated in the ventilation passage 9 near the facing surface facing the open end of each passage 2 of the dehumidifier 1. The first temperature sensor 20 and the second temperature sensor 21 are the controller 2 incorporated in the main body casing 11.
2 and the detection outputs of both are input to the controller 22. The operations of the heater 14, the electric dampers 15 and 17, and the blower 13 are controlled by the controller 22.

As shown in FIG. 5, the static dehumidifier of the above structure uses the space above the ceiling so that the indoor suction port 8 and the indoor air outlet 7 face and open on the ceiling surface of the room such as the bathroom 10. Installed. One end of the exhaust passage 16 is connected to the outside by a duct 23. In this apparatus, the electric dampers 15 and 17, the blower 13 and the heater 14 are controlled by the controller 22, and the switching between the dehumidifying process and the regenerating process is repeated to make the installed room a dry atmosphere. That is, in the dehumidification process, the blower 13 is operated and the electric damper 15 in the exhaust passage 16 is operated.
Is maintained closed, and the electric damper 17 of the ventilation passage 9 is closed.
Is opened and the regeneration passage 18 is closed, so that the heater 14 is de-energized.

As a result, the air in the room is sucked into the ventilation passage 9 from the indoor suction port 8 by the blower 13. The sucked air passes through the respective passages 2 of the dehumidifier 1 in the direction of the solid line arrow in the figure, is blown out from the indoor air outlet 7 into the room, and the indoor air circulates. The air in the room sucked by passing through each passage 2 of the dehumidifier 1 interposed in the ventilation path 9 is dehumidified and returned to the room as dry air, whereby a dry atmosphere in the room progresses.

In the regeneration process performed after the dehumidification process, the operation of the blower 13 is continued, the electric damper 15 of the exhaust passage 16 is opened, and the electric damper 17 of the ventilation passage 9 is opened.
Is closed and the regeneration passage 18 is opened so that the heater 14 is energized. As a result, the blower 1
Due to 3, the air in the room is sucked into the ventilation passage 9 from the indoor suction port 8. The sucked air flows into the ventilation passage 9 from the heater 14 side through the regeneration passage 18. Then, a part of the exhaust gas passes through the heater 14 and is heated to about 140 ° C., the temperature distribution is made uniform by the uniform plate 19, and passes through each passage 2 of the dehumidifier 1 in the direction of the dotted line arrow in the figure, and the exhaust gas is open. The air is exhausted from the passage 16 to the outside to ventilate the inside of the room. When the hot air passes through the passages 2 of the dehumidifier 1 interposed in the ventilation passage 9, the dehumidifier 1 absorbed in the previous dehumidification process is dehumidified, and the dehumidifier 1 is regenerated.

The air in a part of the room that has passed through the regeneration passage 18 returns to the room from the indoor outlet 7 and forms a circulation flow in the room, although not many. Therefore, even in the regeneration process, the room is dried to some extent. By alternately repeating the dehumidifying process and the regenerating process, the bathroom and the like can be ventilated and dried. When the items to be dried 24 such as clothes are hung in the bathroom 10 to be dried, the drying time becomes shorter when the drying atmosphere has a higher degree of drying. However, it is also an important factor that shortens the drying time by promptly separating and removing the moisture taken from the material to be dried 24 from the material to be dried 24. In this static dehumidifier, a part of the air circulates in the regeneration process as described above, and the moisture stripped off by the exhaust air is discharged to the outside, so that the moisture can be quickly separated from the material to be dried 24. The drying time is shortened.

The transition from the dehumidifying process to the regenerating process and the transition from the regenerating process to the dehumidifying process are performed by the controller 22 based on the detection values of the first temperature sensor 20 and the second temperature sensor 21. In the dehumidification process, as dehumidification progresses, the temperature rise due to heat of adsorption decreases, and if the adsorption capacity of the dehumidifier 1 is lost, the temperatures on the upstream side and the downstream side of the dehumidifier 1 are in equilibrium. At the time when these temperatures reach a predetermined temperature difference before equilibrium, the controller 22 shifts to the regeneration process.
Works. Further, in the regeneration process, as the dehumidification progresses, the temperature drop due to the dehumidification decreases, and if the dehumidification of the dehumidifier 1 is eliminated, the upstream side and the downstream side of the dehumidifier 1 are in a high temperature and equilibrium state. At the time when these temperatures reach a predetermined temperature difference before reaching equilibrium, the controller 22 shifts to the dehumidification process.
Works. As a result, it is possible to accurately grasp the moisture absorption / regeneration of the dehumidifier 1 and automatically switch the dehumidification / regeneration.

The dehumidifying capacity of the dehumidifier 1 is influenced by the temperature, and the lower the temperature, the higher the dehumidifying capacity. Therefore, when the dehumidifier 1 is regenerated until the regeneration is completed, the temperature of the dehumidifier 1 shifts to the dehumidification step. Therefore, it is not preferable. The static dehumidifier according to the second embodiment utilizes the dehumidifying method shown in the first embodiment. In the dehumidifying process and the regenerating process, the directions of the air streams passing through the dehumidifier 1 are made opposite to each other to form a counter flow. Therefore, the effect as shown in the first embodiment can be directly obtained.

As described above, since the air in the room is circulated in the dehumidifying process, the function of the dehumidifying process is used as it is, and the heater 14 which is not normally used in the dehumidifying process is operated to heat the room. it can. In this case as well, in this static dehumidifier in which the heater 14 is located on the downstream side of the dehumidifier 1, since hot air does not pass through the dehumidifier 1 and the heat is not taken by the dehumidifier 1, the heat of the heater 14 is heated for heating. Can work effectively. Further, it is possible to prevent the dehumidifier 1 from being thermally deteriorated due to continuous heating operation for a long time. This heating operation can be incorporated in the dehumidification process. That is,
When the room temperature is low or when it is desired to dry the material to be dried 24 quickly, the heater 14 is operated even during the dehumidification process, and if the room temperature is raised, evaporation of water is promoted and the drying time can be shortened.

Further, as described above, in the regeneration process, the indoor air is exhausted so that the indoor ventilation is carried out. However, since the dehumidifier 1 is passed, only a small air volume ventilation can be expected, and a large air volume ventilation is expected. Can not be dealt with when needed. In this static dehumidifier, the electric damper 17 is switched to the side that closes the regeneration passage 18, the electric damper 15 in the exhaust passage 16 is opened, and the blower 13 is operated.
The air in the room blown out from the room can be exhausted to the outside through the exhaust passage 16 without passing through the dehumidifier 1. That is, ventilation of a large air volume can be carried out if necessary, and has an expanded function.

The switching between the dehumidifying process and the regenerating process may be performed by incorporating a timer in the controller 22 and setting the time by the timer. An apparatus for drying the bathroom 10 may be set to perform a dehumidification process for about 3 to 5 minutes and then a regeneration process for about 2 minutes. Further, even if the first temperature sensor 20 and the second temperature sensor 21 are replaced with the first humidity sensor 25 and the second humidity sensor 26, the transition between the dehumidifying process and the regenerating process can be automatically performed. . That is, in the dehumidification process, as dehumidification progresses, the adsorption capacity of the dehumidifier 1 decreases, and the humidity on the upstream side and the downstream side of the dehumidifier 1 eventually reach an equilibrium state. When the humidity reaches a predetermined difference before the equilibrium is reached, the controller 22 may be operated to shift to the regeneration process. Further, in the regeneration process, as the moisture release progresses, the amount of moisture release decreases and the dehumidifier 1
The upstream and downstream humidities will eventually reach equilibrium. When the humidity becomes a predetermined humidity difference before equilibrium, if the controller 22 is operated so as to shift to the dehumidification process, the dehumidification / regeneration can be automatically switched like the temperature sensor. .

The uniform plate 19 is a functional component for eliminating the unevenness of the heat distribution of the air flow by the heater 14 and sending it to the dehumidifier 1 after uniformizing it. By providing the uniform plate 19, the regeneration function in the regeneration process is stabilized. In addition, the dehumidifier 1 can be prevented from deteriorating due to radiant heat of the heater 14, but since it is accompanied by a pressure loss, it is not an indispensable part, and even if it is removed, the above-mentioned respective functions are not hindered. .

Similar to the dehumidifying process, the electric dampers 15 and 17
By switching between, the heater 14 is stopped, and the blower 13 is operated, a part of the room can be ventilated while circulating the air. As a result, a small amount of air is ventilated through the exhaust passage 16 with an appropriate amount of air, and along with this, the regeneration passage 1
The air in the room can be circulated by 8 and the indoor air outlet 7. In the bathroom 10 and the like after taking a bath, the ventilation operation can dry the wall surface, floor, etc., and it is possible to suppress the generation of mold and the like.

By operating the auxiliary heater 27 together with the heater 14, quick heating can be performed. Further, when the room temperature is low or when it is desired to dry the object to be dried 24 quickly, the room temperature can be raised by operating only the auxiliary heater 27, the evaporation of moisture can be promoted, and the drying time can be shortened. . The other configurations and functions are the same as those of the second embodiment, and therefore their explanations are omitted.

This is the same as the static dehumidifier shown in the second mode. Therefore, the same portions as those of the second embodiment are denoted by the same reference numerals, and description thereof is omitted.

The ventilation passages 2 are intervened in the middle of the ventilation passages 9 that are open to the inside of the room as the entrance ends. The ventilation passage 9 is defined in a main body casing 11 attached to the ceiling or the like of a room to be dehumidified such as a bathroom, and the indoor suction port 8 and the indoor air outlet 7 are separated from each other on the lower surface of the main body casing 11. It opens toward the room. The indoor suction port 8 and the indoor air outlet 7 are provided with grills, and filters 12 are attached to the insides of these grills.
