Description

  The present invention relates to a dehumidifying / humidifying device that exhibits both a dehumidifying function and a moisture absorbing function.

  Patent Document 1 listed below describes a dehumidifying device including a hygroscopic element and a blower. Although FIG. 12 of the said patent document 1 is disclosing the structure provided with the several moisture absorption element, each moisture absorption element cannot be controlled independently (all the moisture absorption elements are a moisture absorption state at once). In other words, the humidity is rapidly increased or decreased in a short time. Therefore, it is difficult to adjust the humidity so as to be within a predetermined range.

Japanese Patent Laid-Open No. 9-24235

  An object of this invention is to provide the dehumidification / humidification apparatus with easy adjustment of humidity.

  The dehumidifying / humidifying device according to the present invention, which has been made to solve the above-mentioned problems, has a plurality of absorption / desorption devices that can be changed between a moisture absorption state that adsorbs moisture in the air and a moisture release state that releases the absorbed moisture into the air. And a control unit capable of independently controlling each of the plurality of moisture absorbing / releasing units to be in the moisture absorbing state or the moisture releasing state.

  Blower means for generating a flow of air in a predetermined direction during a moisture release operation for releasing moisture adsorbed by the plurality of moisture absorption / release units into the air, and the plurality of moisture absorption / release units in the predetermined direction The control means is arranged to sequentially enter the moisture release state from the moisture absorption / release unit located upstream of the air flow toward the predetermined direction during the moisture release operation. It is good to control.

  Blower means for generating a flow of air in a predetermined direction during a moisture release operation for releasing moisture adsorbed by the plurality of moisture absorption / release units into the air, and the plurality of moisture absorption / release units in the predetermined direction The control means is configured to sequentially enter the moisture release state from the moisture absorption / release unit located on the downstream side of the air flow toward the predetermined direction during the moisture release operation. In addition, it may be controlled so that the moisture release state of each moisture release unit is maintained until a predetermined time elapses when the moisture absorption / release unit located on the most upstream side becomes a moisture release state.

  The moisture absorption / release unit is improved in moisture absorption due to a decrease in temperature, and the plurality of moisture absorption / release units have one or more responsiveness of temperature decrease than other moisture absorption / release units. The specific moisture absorption / release unit may be included, and the specific moisture absorption / release unit may be disposed outside.

  By collecting moisture in the air by the plurality of moisture absorption / release units and locally releasing the adsorbed moisture, it can be applied as a local humidification device that locally increases the humidity at a specific location.

  Since the dehumidifying / humidifying device according to the present invention can control each of the plurality of moisture absorption / release units independently, the humidity can be easily adjusted.

  When a plurality of moisture absorption / release units are provided so as to be aligned along the direction of air flow, a certain moisture absorption / desorption unit is controlled by sequentially controlling the moisture absorption / release units located upstream of the air flow. It can suppress that the water | moisture content discharge | released from the moisture release unit will be adsorb | sucked by the moisture absorption / release unit downstream from it.

  When a plurality of moisture absorption / release units are provided so as to be aligned along the direction of air flow, the moisture absorption / release unit is located in the most upstream side so that the moisture release state is in order from the moisture absorption / release unit located on the downstream side. By controlling so that the moisture release state of each moisture release unit is maintained until a predetermined time elapses when the moisture unit becomes moisture release, the moisture released from one moisture absorption / release unit is more downstream than that. It can suppress adsorbing | sucking to a moisture absorption / release unit.

  By placing a specific moisture absorption / release unit that has a higher temperature responsiveness than other moisture absorption / release units on the outside, the specific moisture absorption / release unit can be cooled more easily. Becomes faster.

It is a figure for demonstrating the dehumidification / humidification apparatus concerning a 2nd modification.

  The dehumidifying / humidifying device 1 according to an embodiment of the present invention will be described in detail. A dehumidifying / humidifying device 1 according to this embodiment shown in FIG. 1 includes a moisture absorption / release unit 10 and a control means 20. The moisture absorbing / releasing unit 10 uses a moisture absorbing substance 11 that releases moisture adsorbed by raising the temperature and adsorbs moisture in the air by lowering the temperature. In the present embodiment, the temperature of the hygroscopic substance 11 is controlled by controlling the application (energization) of electrical energy. Examples of the hygroscopic substance 11 include conductive carbon and conductive polymer. The moisture absorption / release unit 10 in the present embodiment has a structure in which planar hygroscopic substances 11 are laminated at a predetermined interval. That is, the moisture absorption / release unit 10 has air permeability.

  The dehumidifying / humidifying device 1 according to the present embodiment includes a plurality of such moisture absorbing / releasing units 10. The moisture absorption / release unit 10 is accommodated in the ventilation path 30. The ventilation path 30 is a passage for wind (air flow) generated by the air blowing means 40 (fan). The air blowing means 40 has a state in which the flow of air in the ventilation path 30 flows from one side of the ventilation path 30 to the other side (hereinafter, the direction in which the air flows is sometimes referred to as a first direction) and from the other side. The state can be switched to one of the states that flow to one side (hereinafter, the direction in which the air flows may be referred to as a second direction). By using a plurality of air blowing means 40 (see FIG. 1), the air flow in the first direction and the second direction may be generated, or by switching between normal rotation and reverse rotation of one air blowing means 40, You may make it produce the flow of the air of a 1st direction and a 2nd direction. The plurality of moisture absorption / release units 10 are arranged along the ventilation path 30, that is, along the air flow generated by the air blowing means 40. In the present embodiment, four moisture absorption / release units 10 are provided. In the following description, the first moisture absorption / release unit 101, the second moisture absorption / release unit 102, the third moisture absorption / release unit 103, and the fourth moisture absorption / release unit 104 may be referred to in order from the left side in FIG.

  The control means 20 controls the switch 21 provided corresponding to each moisture absorption / release unit 10. When each switch 21 is turned on, the corresponding moisture absorption / release unit 10 is energized. In the following description, the switches 21 corresponding to the first to fourth moisture absorption / release units 104 may be referred to as a first switch 211, a second switch 212, a third switch 213, and a fourth switch 214, respectively. By energizing the moisture absorbing / releasing unit 10 in this way, the temperature of the moisture absorbing / releasing unit 10 (hygroscopic substance 11) rises and the moisture adsorbed in the moisture absorbing / releasing unit 10 is released into the air. It becomes. When the energization is stopped, the temperature of the moisture absorption / release unit 10 (the moisture absorption substance 11) decreases, and the moisture absorption / release unit 10 is in a moisture absorption state in which moisture in the air is adsorbed until the moisture absorption / release unit 10 is saturated. As shown in FIG. 1, in this embodiment, one DC power supply 22 is provided for the two moisture absorption / release units 10. That is, a circuit in which two moisture absorption / release units 10 supply one power supply 22 is constructed. One power supply 22 may be provided for one moisture absorption / release unit 10.

  Control (operation) by the control means 20 of the dehumidifying / humidifying device 1 configured as described above will be described. The dehumidifying / humidifying device 1 according to the present embodiment collects moisture from the air in the room (external) where the device is installed, and discharges the collected moisture toward a specific location in the room. That is, it is an apparatus for performing local humidification. Although the humidity of the entire room in which the apparatus is installed does not change, it can be said that the apparatus has a deviation in the humidity distribution in the room (the humidity in a specific area in the room is higher than in other areas). As shown in FIG. 2, for example, by installing the apparatus so that high-humidity air is sent toward the vicinity of the face of the user lying on the bed, a moisturizing action during sleeping is brought about.

  First, the control means 20 executes a moisture absorption process for causing the moisture absorption / release unit 10 to adsorb moisture in the air. In the moisture absorption process, the flow of air by the blowing means 40 is the first direction. All moisture absorption / release units 10 are in a non-energized state (all switches 21 are turned off). That is, all the moisture absorption / release units 10 are in a moisture absorption state. By setting it as such a state, the external air is taken in into the ventilation path 30 from the one side of the ventilation path 30 by the air flow produced by the ventilation means 40, and the water | moisture content contained in the air is installed in the ventilation path 30. It is adsorbed by the moisture absorbing / releasing unit 10 (moisture absorbing material 11). The air deprived of moisture is discharged to the outside from the other side of the ventilation path 30. In this way, moisture in the air is collected by the moisture absorption / release unit 10.

  The collected moisture in the air is released into the air by the moisture release process. In the moisture release process, the flow of air by the blowing means 40 is set to the second direction. And the several moisture absorption / release unit 10 is made into a moisture release state in order. As shown in FIG. 3, in this embodiment, the first moisture absorption / release unit 101 located on the upstream side in the air flow direction (second direction) sequentially enters the moisture release state (FIGS. 3B to 3B). (See (d)). That is, the moisture absorption state is set in the order of the first moisture absorption / release unit 101, the second moisture absorption / release unit 102, the third moisture absorption / release unit 103, and the fourth moisture absorption / release unit 104. In other words, the control means 20 controls each switch 21 to be turned on in the order of the first switch 211, the second switch 212, the third switch 213, and the fourth switch 214.

  By controlling in this way, the moisture collected in the moisture absorption process is sequentially released from the first moisture absorption / release unit 101 on the air flow flowing in the second direction. That is, high-humidity air is released to the outside. Such a moisture absorption process and a moisture release process are repeated to repeatedly release high-humidity air to the outside.

  In the moisture release process, the moisture release state in order from the first moisture absorption / release unit 101 is that moisture released from the moisture absorption / release unit 10 located on the upstream side in the air flow direction (second direction) It is for suppressing adsorbing | sucking to the moisture absorption / release unit 10 located in the downstream rather than that. Moisture released from a certain moisture absorbing / releasing unit 10 (excluding the fourth moisture absorbing / releasing unit 104 located on the most downstream side) rides on air flowing in the second direction and is positioned on the downstream side. It will pass through the wet unit 10. At that time, if the released moisture is adsorbed by the moisture absorption / release unit 10 located on the downstream side, the amount of moisture output from the device (the outlet of the ventilation path 30) is reduced. Therefore, it is preferable that the moisture absorption / release unit 10 located on the downstream side has a low adsorbing ability (the closer to the saturated state, the better). Therefore, in this embodiment, it is set as the moisture release state in order from the 1st moisture absorption / release unit 101 located in an upstream. In addition, the moisture absorption / release unit 10 that has completed the moisture release may be sequentially switched to the moisture absorption state (see FIGS. 3C and 3D), or the last moisture absorption / release unit 10 may release moisture. You may make it maintain a moisture release state until completion. By sequentially switching to the moisture absorption state, when the moisture absorption / desorption unit 10 located on the most downstream side is completed, the moisture absorption / desorption unit 10 on the upstream side of the moisture absorption / desorption unit 10 has advanced moisture adsorption. Therefore, there is an advantage that switching between moisture release and moisture absorption becomes faster.

  Thus, since the dehumidifying / humidifying device 1 according to the present embodiment can control each of the plurality of moisture absorption / release units 10 independently, the humidity can be easily adjusted. Specifically, in the moisture release process, a plurality of moisture absorption / release units 10 are sequentially put into a moisture release state, so the amount of moisture released at a time is a maximum of one moisture absorption / release unit 10 minutes. . Therefore, as shown in FIG. 4 (indicated by a dotted line), the humidity of the air released from the apparatus in the moisture release process repeats a state of rising and falling in small increments, and the humidity of the released air is within a predetermined range. It is easy to be contained (contained within an appropriate humidity range (for example, humidity 50 to 80%)). As shown in FIG. 4 as a reference (indicated by a one-dot chain line), an integrated moisture absorbing / releasing unit in which a plurality of moisture absorbing / releasing units 10 according to the present embodiment are grouped (the volume of the moisture absorbing substance 11 with the present embodiment is the same as that of FIG. In the moisture release process of the apparatus provided with the same moisture absorption / release unit), the moisture is greatly increased in a short time by releasing the adsorbed moisture at a time. Since each unit has a small amount of moisture absorption and release, and these units can be controlled independently, a significant increase in humidity in a short time is suppressed (uniform humidity) Can be achieved). Further, the dehumidifying / humidifying device 1 according to the present embodiment releases moisture sequentially from each of the moisture absorbing / releasing units 10, so that the moisture releasing / releasing device (relative to the integrated moisture absorbing / releasing unit) is released. There is also an advantage that the time during which the wet state continues is prolonged.

  In the moisture release process of the present embodiment, the moisture absorption / release units 10 are controlled so that the moisture absorption / release units 10 are sequentially put into a moisture release state. It may be done. For example, if the humidity of the output air does not become the required humidity only by putting one moisture absorption / release unit 10 into the moisture release state, the plurality of moisture absorption / release units 10 are brought into the moisture release state at once. , And so on. Since each of the moisture absorbing / releasing units 10 can be controlled independently, the moisture absorbing / releasing units 10 can be operated one by one as in the above moisture releasing step, or can be operated differently. It can also be made.

  The dehumidifying / humidifying device 1 according to the present embodiment is mainly intended for “humidifying” (outputting high-humidity air) (dehumidifying is performed, but the dehumidifying is for humidification). Therefore, the plurality of moisture absorption / release units 10 are controlled to be sequentially in a moisture release state in the moisture release process. On the other hand, when the main purpose is “dehumidification”, it is preferable to control the plurality of moisture absorption / release units 10 to be sequentially in a moisture absorption state in the moisture absorption process.

  Moreover, the following are mentioned as another advantage of the dehumidification / humidification apparatus 1 concerning this embodiment. Since the air blowing means 40 in this embodiment can switch the direction of air flow, even if dust or the like adheres to the moisture absorption / release unit 10 or the ventilation path 30, it can be blown away with air. If the temperature of the moisture absorption / release unit 10 during energization rises to about 60 degrees, generation of mites, molds, and the like can be suppressed. Since the temperature of the moisture absorption / release unit 10 is controlled by energizing the moisture absorption / release unit 10 directly, the energy efficiency is high (compared to a device heated by high-temperature air).

  Hereinafter, a modified example of the dehumidifying / humidifying device 1 according to the above embodiment will be described focusing on differences from the above embodiment. It is good also as an apparatus applied combining the modification demonstrated below.

-1st modification Although the said embodiment demonstrated that it was made into a moisture release state in order from the moisture absorption / release unit 10 located in the upstream in a 2nd direction in the moisture release process, the moisture release / release located in a downstream side. You may make it make it a moisture release state in order from the moisture unit 10. FIG. That is, if it is an apparatus provided with the four moisture absorption / release units 10 like the said embodiment, as shown in FIG. 5, the 4th moisture absorption / release unit 104, the 3rd moisture absorption / release unit 103, and the 2nd moisture absorption / release unit. Control is performed so as to change from the moisture absorption state to the moisture release state in the order of the moisture unit 102 and the second moisture absorption / release unit 102. In this case, the release of each moisture release unit is performed until the first moisture absorption / release unit 101 located on the most upstream side is in the moisture release state and a predetermined time has elapsed (until the moisture release of the first moisture absorption / release unit 101 is completed). Maintain humidity. That is, the fourth moisture absorption / release unit 104 is first in a moisture release state, and then the third moisture absorption / release unit 103 is in a moisture release state, but even if the third moisture absorption / release unit 103 is in a moisture release state, The moisture release state of the fourth moisture absorption / release unit 104 is maintained (see FIG. 5C). Then, even if the 2nd moisture absorption / release unit 102 will be in a moisture release state, the moisture release state of the 4th moisture absorption / release unit 104 and the 3rd moisture absorption / release unit 103 is maintained. Finally, the fourth moisture absorption / release unit 103, the third moisture absorption / release unit 103, and the second moisture absorption / release unit 102 are dehumidified until a predetermined time elapses after the first moisture absorption / release unit 101 enters the moisture release state. The state is maintained (see FIG. 5D).

  The reason for controlling in this way is as follows. Moisture generated when a moisture absorption / release unit 10 other than the fourth moisture absorption / release unit 104 located on the most downstream side in the second direction is in a moisture release state rides on the air flow in the second direction. It passes through the moisture absorption / release unit 10 located on the downstream side. Therefore, in order to prevent moisture from being adsorbed to the moisture absorption / release unit 10 located downstream of a certain moisture absorption / release unit 10, the moisture release state of the moisture absorption / release unit 10 located downstream is maintained (moisture absorption). Not state.)

  Also in this example, as in the above embodiment, the humidity of the air released from the device in the moisture release process repeats a state of rising and falling in small increments, and the humidity of the released air falls within a predetermined range. Becomes easier.

Second Modification The above embodiment is based on the premise that each of the plurality of moisture absorption / release units 10 has the same ability (the same amount of moisture absorption per unit volume, moisture absorption rate and moisture release rate). However, the capacity | capacitance of one part moisture absorption / release unit 10 in the some moisture absorption / release unit 10 and another one part moisture absorption / release unit 10 may differ. As a suitable example, the following configuration can be cited.

  Among the plurality of moisture absorption / release units 10, some of the moisture absorption / release units 10 have other moisture absorption / release units 10 (here, formally referred to as normal moisture absorption / release units 10 b) because of their responsiveness to moisture absorption during cooling. The specific moisture absorption / release unit 10a is included. Various methods for increasing the responsiveness of the hygroscopic action during cooling are conceivable. For example, the following configuration is adopted. The specific moisture absorption / release unit 10 a includes a plate-like base member 12 that supports the moisture-absorbing substance 11. The hygroscopic substance 11 is fixed to the surface of the base member 12. The specific moisture absorption / release unit 10a is configured by placing the base member 12 (see FIG. 6A) to which the moisture absorption material 11 is fixed at a predetermined interval. The base member 12 is made of a conductive material (for example, aluminum or copper). By energizing the base member 12, the temperature of the base member 12 increases, and by stopping energization, the temperature of the base member 12 decreases. When the temperature of the base member 12 rises, the moisture adsorbed by the hygroscopic substance 11 is thereby released (becomes a moisture release state). When the temperature of the base member 12 decreases, moisture in the air is adsorbed by the hygroscopic substance 11 (becomes a hygroscopic state).

  By using such a base member 12, the responsiveness to the outside air temperature is increased. That is, the specific moisture absorption / release unit 10a using the base member 12 is more sensitive to the moisture absorption / release unit (usually moisture absorption / release unit 10b) that does not use the base member 12 because of the responsiveness of the temperature drop when the energization is stopped. It becomes higher than that.

  In this example, a plurality (three or more) of two types of moisture absorption / release units 10 having different responsiveness to such temperature decrease are provided. Similar to the above embodiment, the plurality of moisture absorption / release units 10 are arranged along the direction in which the air flows. Among the plurality of moisture absorbing / releasing units 10 arranged in this manner, the specific moisture absorbing / releasing unit 10a is disposed outside. For example, as shown in FIG. 6 (b), two specific moisture absorption / release units 10a are arranged outside in the direction of air flow, and the remaining two normal moisture absorption / release units 10b are connected to the two specific moisture absorption / release units 10a. It is arranged inside so as to be sandwiched between them.

  The advantages of such a configuration are as follows. When it arrange | positions so that the some moisture absorption / release unit 10 may be located in a line along the direction through which air flows, the moisture absorption / release unit 10 located in the outer side is easy to be cooled with external air. Therefore, when the moisture release state (energized state) is switched to the moisture absorbed state (non-energized state), the temperature of the moisture absorbent / release unit 10 located on the outside quickly decreases. In this example, the moisture absorbing / releasing unit 10 located on the outside is the specific moisture absorbing / releasing unit 10a whose temperature is likely to decrease due to the presence of the base member 12, so that the responsiveness when switching from moisture releasing to moisture absorbing is accelerated. . That is, when the switching is performed, the specific moisture absorption / release unit 10a is in a state where moisture can be quickly absorbed, so that it is possible to shorten the time until the next switching to the moisture release state.

  In the configuration shown in FIG. 6B, a plurality of moisture absorption / release units 10 are arranged along the air flow direction, and the specific moisture absorption / release unit 10a is disposed on both outer sides in the air flow direction. Although it is arranged, as shown in FIG. 6C, the specific moisture absorption / release unit 10a may be arranged only on one outer side. In that case, the specific moisture absorption / release unit 10a may be disposed on the most upstream side in the direction of air flow (first direction) during moisture absorption. That is, by setting the moisture absorption / release unit 10 to which the moisture of the outside air first reaches as the specific moisture absorption / release unit 10a, it is possible to provide a device that has quick response when switching from moisture release to moisture absorption.

  In addition, in this example, it has been described that the two types of moisture absorption / release units 10 having different responsiveness to temperature decrease are provided. However, three or more types of moisture absorption / release units having different responsiveness to temperature decrease are described. 10 may be provided. When the moisture absorption / release unit 10 having a high temperature responsiveness is preferentially placed outside (the highest priority is on the most upstream side in the first direction), thereby switching from moisture release to moisture absorption. It can be set as a device with quick response.

  As mentioned above, although embodiment (and its modification) of this invention was described in detail, this invention is not limited to the said embodiment (and its modification) at all, and in the range which does not deviate from the summary of this invention. Various modifications are possible.

  For example, the dehumidifying / humidifying device 1 according to the above-described embodiment (and its modification) is a device for performing local humidification (the humidity of the entire room where the device is installed does not change). Although described, the same technical idea can be applied to devices other than this type. For example, the same technical idea can be applied to a device in which a device is installed so as to straddle a room and the outdoors and the room is humidified or dehumidified.
