Description

  The present invention relates to a dehumidifying device that removes moisture contained in room air mainly using a hygroscopic agent.

  In recent years, high airtightness and high thermal insulation of houses have progressed, and it has been a problem that moisture generated with human life accumulates in room air. Specifically, water vapor generated during cooking, steam that diffuses from the bathroom to the room during bathing, water vapor generated when the laundry is dried indoors, moisture released as sweat from the human body, etc. Moisture from various sources accumulates in room air, increasing humidity. Further, when the indoor humidity increases or the temperature of indoor air containing a lot of moisture decreases, condensation may occur in a place where ventilation is insufficient or where the temperature is locally low. Specifically, dew condensation is likely to occur when the temperature of the wall surface is lower than the surrounding temperature in a place where air circulation is low, such as in a wall of a closet or in a lower leg box.

  To deal with such problems, dehumidifying agents using calcium chloride and the like are currently on the market, and are used by installing them in narrow spaces such as closets and lower leg boxes. However, once the moisture in the air is absorbed, calcium chloride dissolves and becomes an aqueous solution. Therefore, such a dehumidifying agent is not easy to regenerate and is used at present.

  On the other hand, a small dehumidifying device has been proposed as a device for continuously dehumidifying a narrow space such as a closet or a lower leg box (for example, see Patent Document 1).

  Hereinafter, the dehumidifier will be described with reference to FIG. FIG. 14 shows a schematic configuration of the structure of the dehumidifier. As shown in FIG. 14, a conventional close-in dehumidifying device 101 includes a rotary moisture absorption rotor 102 that is configured to allow ventilation of dehumidified air and regeneration air, a heater 103 that heats regeneration air, and heated regeneration air. A heat exchanger 104 for condensing moisture by cooling the high-temperature and high-humidity air by desorbing moisture from the moisture-absorbing rotor, a water storage tank 105 for storing condensed water, and sucking the dehumidified air from an intake port. A dehumidifying fan 106 that passes through the inside of the moisture absorption rotor and sends dry air from an exhaust port, and a regeneration fan 107 that sends regeneration air in the order of the heater, the moisture absorption rotor, and a heat exchanger are provided in the body, and the body is elongated. It is characterized by being composed.

As shown in FIG. 15, it is assumed that the close-in dehumidifier is installed in a clearance inside the close-up.

Although the composition of the hygroscopic agent is not shown in the present invention, it is preferable to include at least one inorganic substance of silica gel and clay as the hygroscopic agent. As silica gel, there are JIS standard type A silica gel, RD type silica gel, ID type silica gel, B type silica gel, etc. When relatively high adsorption speed is not required, granular silica gel can be used and when the absorption speed is required May support powdered silica gel on the surface of a honeycomb molded body or the like, or the silica gel itself may be mixed with a binder or the like to be used as an extrusion molded body.

Examples of the breathable material include OPP / PE, paper / PE, and nonwoven fabric / PE. It is also possible to provide a small hole with a needle hole in these films and adjust the moisture absorption speed by the number and size thereof.

  The subunit | mobile_unit 2 comprised by such a hygroscopic agent is the required minimum magnitude | size which does not have a reproduction | regeneration means etc., and can be installed in narrow spaces, such as the clearance of a closet, and the clearance of a leg box. In addition, moisture absorption starts when it comes into contact with the air in the enclosed space, so there is no need for a power supply, and there is no need to search for an outlet for supplying power, and the installation location is restricted by the distance from the outlet.

In addition, since no power line is required, the door of the closet or foot box can be sealed, and the dehumidification rate by the slave unit can be improved compared to the case where there is a clearance for the power line to pass through the door. it can.

  Although details of the regeneration means were not described, if the silica gel of the slave unit is to be regenerated, there are a method of increasing the temperature of the silica gel, a method of supplying dry air to the silica gel, a combination of these methods, and the like. Conceivable. A heat exchanger and a drain pan for collecting water vapor desorbed from the silica gel as water droplets may be combined. In this embodiment, the child machine 2 is mounted in the recess of the parent machine 4 so that the hot and / or dry air generated by the regeneration means 3 regenerates the hygroscopic agent 1.

Unlike the slave unit, the master unit does not need to be installed in a narrow closed space, so it can be installed in a location near the outlet.

However, the present invention is not limited to this combination, and the same effect can be obtained even when a plurality of child devices are used in one parent device. .

(Embodiment 2)
FIG. 2 is a schematic diagram showing a schematic configuration of the inside of the slave unit 2 from the lateral direction. As shown in FIG. 2, the handset 2 is provided with air circulation means 6, and when the handset is installed in a narrow closed space by the action of the air circulation means 6, the surrounding air is sucked into the handset. It has a function to do. Specifically, an air circulation means 6 is provided at a portion facing the opening of the exterior of the slave unit 2 to suck ambient air into the slave unit. The air sucked into the handset passes through the vicinity of the hygroscopic agent 1 and is discharged from the opening of the exterior of the handset 2 on the opposite side of the air circulation means 6.

  The arrangement of the air circulation means is not limited to this configuration, and the same effect can be obtained if the arrangement is such that the air around the child device 2 can be efficiently sucked and brought into contact with the moisture absorbent 1. be able to. The air circulation means 6 is only required to be able to circulate the air. For example, the air circulation means 6 is heated by a fan that generates a circulating air flow, a hygroscopic agent such as silica gel that generates an ascending air flow by heat and generates adsorption heat, or a heater. There are stones.

(Embodiment 3)
FIG. 3 is a schematic diagram showing a schematic configuration of the inside of the slave unit 2 from the lateral direction. The subunit | mobile_unit 2 has shown the state installed in the floor surface. As shown in FIG. 3, the handset 2 is provided with an air circulation means 6 using the heat of adsorption of the moisture absorbent 1. Specifically, a cylindrical flow path 7 that passes in the vicinity of a hygroscopic agent such as silica gel and has openings at the upper and lower portions of the child device 2 is provided inside the child device 2. Since the flow path 7 has an opening on the lower surface of the child device 2, the air around the child device 2 can be sucked through the gap between the child device 2 and the floor surface. When moisture in the air is adsorbed to the hygroscopic agent 1 such as silica gel in the slave unit 2, the air in the flow path near the hygroscopic agent is heated by the heat of adsorption. As a temperature gradient is generated in the air in the cylindrical flow path 7, an air flow is generated from below to above in the cylindrical flow path 7. As a result, ambient air can be sucked from the lower opening of the child device 2. The positional relationship between the opening, the hygroscopic agent, and the flow path is not limited to the arrangement in this figure, and the same effect can be obtained if the arrangement is such that a temperature gradient is generated by the adsorption heat of the hygroscopic agent. It can be done. Further, the shape of the cylindrical flow path is not limited to this structure, and the cross-sectional shape of the flow path is not limited.

(Embodiment 4)
FIG. 4 is a schematic diagram showing a schematic configuration of the inside of the slave unit 2 from the lateral direction. As shown in FIG. 4, the subunit | mobile_unit 2 is provided with the ventilation means 8 as the air circulation means 6. As shown in FIG. The blowing means 8 includes a fan that operates by a driving source such as a battery. Since the blowing means is not a mechanism for generating heat unlike the regenerating means, a predetermined operation can be realized with a relatively small dry battery or secondary battery. In addition, a method of effectively using the battery by performing intermittent operation can be used. Since the surrounding air can be sucked by the air flow generated by the blowing means as in the third embodiment, the dehumidifying efficiency in the closed space by the slave unit 2 can be improved. The structure of the blowing means is not particularly limited, and any method can be used regardless of the shape of the blades as long as the method has a function for transferring air. it can. In addition, since it is necessary to allow ambient air to pass through the hygroscopic agent having a structure with a relatively high pressure loss, a structure such as a sirocco fan is suitable as the shape of the blade.

(Embodiment 5)
As shown in FIG. 5, the slave unit 2 is provided with display means 9. The display means 9 may be configured so that the user can recognize information such as an LED or a liquid crystal panel. Since the display means 9 displays the time since the use of the slave unit is displayed, it can be used as a guide for knowing the timing of reproducing the slave unit. Further, as described later, if various detection means capable of detecting the ambient temperature, humidity, and the like of the slave unit are incorporated in the slave unit, the detection results of the various detection units are displayed, so that the slave unit 2 It can be used as a standard for dehumidifying effect.

(Embodiment 6)
As shown in FIG. 6, the child device 2 is provided with a sound generating means 10 such as a buzzer or a speaker. Since it assumes that the subunit | mobile_unit 2 is installed in a narrow closed space, the case where it installs in the position which cannot be easily seen from the circumference | surroundings is also assumed. Therefore, by using the sound generating means 10, the state of the handset 2 can be transmitted to the user. Specifically, it is possible to know the timing for reproducing the slave unit by generating a notification sound when a certain time has elapsed since the start of use of the slave unit 2. Further, as will be described later, as long as various detection means are built in the slave unit, a neglected sound may be generated according to the detection results of the various detection means.

  For example, if the ambient humidity is longer than the set value for a long time, it is necessary to respond by adding a slave unit. You may notify. The notification sound may be properly used depending on the content to be notified. Various detection means only need to be able to detect the surrounding environment, and include a temperature sensor, a humidity sensor, an illuminance sensor, a gas sensor, and the like.

(Embodiment 7)
As shown in FIG. 7, the handset 2 is provided with temperature detection means 11. As the temperature detection means 11, a detection means such as a thermistor or a resistance temperature detector whose electrical characteristics change according to temperature is used. Since the condensation tends to occur when the temperature of the high-humidity air decreases, the temperature detection means 11 detects a change in the ambient temperature. When a sudden temperature drop is detected, the dehumidifying ability is improved by increasing the operation of the air circulation means described above. Alternatively, it is possible to inform the user that there is a possibility of dew condensation using the display means and sound generation means described above. In addition, when a plurality of temperature detection means are provided, the airflow can be detected from the positional relationship with the heating element, so that the operation of the air circulation means can be controlled.

(Embodiment 8)
As shown in FIG. 8, the handset 2 is provided with humidity detecting means 12. As the humidity detecting means 12, a detecting means whose electrical characteristics change according to the humidity, such as a polymer film type humidity sensor, is used. The humidity detector 12 detects a change in the humidity of the surrounding air. When a sudden increase in humidity is detected, the dehumidifying ability is improved by increasing the operation of the air circulation means described above. Alternatively, it is possible to inform the user that there is a possibility of dew condensation using the display means and sound generation means described above.

(Embodiment 9)
As shown in FIG. 9, the handset 2 is provided with illuminance detection means 13. As the illuminance detection means 13, a detection means such as a phototransistor whose electrical characteristics change according to the illuminance is used. The illuminance detection means 13 detects the brightness around the handset 2. Since the handset 2 is supposed to be installed in a narrow closed space, the dehumidifying capability is insufficient when used in an open space. Therefore, when the illuminance detection means determines that the surrounding is bright, the operation of the air circulation means can be stopped. In other words, when the surroundings are bright, the closed space may be open. Therefore, if the air circulation is continued as it is, there is a possibility that the hygroscopic ability of the hygroscopic agent will be immediately reduced. Further, when the state in which the illuminance is lowered continues, it is determined that the closed space is closed, and the dehumidifying ability can be improved by appropriately operating the air circulation means.

(Embodiment 10)
As shown in FIG. 10, the handset 2 is provided with a timer 14. The timer 14 has a structure in which the time is displayed by an LED, a liquid crystal, or the like, and may have any structure that allows the user to set a time to be measured and recognize the elapsed time. The timer 14 starts when the regeneration of the hygroscopic agent by the master unit is completed, and notifies when a certain time has elapsed. That is, the timing at which the dehumidifying ability is considered to be lowered is notified by the timer. If the length of the timer is set in advance according to the capacity of the space to be dehumidified, the capacity of the hygroscopic agent, the humidity of the target space, or the season, the dehumidification can be performed efficiently. For example, in summer, the timer is set with a certain time of 48 hours.

  Even if a hygroscopic agent that absorbs a large amount of moisture and has a reduced hygroscopic capacity is installed, the humidity in the space does not decrease. Thus, dehumidification can be performed efficiently.

  Moreover, it is also possible to appropriately determine a decrease in the capacity of the hygroscopic agent by combining with various detection means such as the temperature detection means and the humidity detection means described above. Specifically, by combining with the signal from the humidity detection means, if the low humidity state continues for a long time, the timer progresses slowly, and if the high humidity state continues for a long time, the timer progresses. The playback timing can be appropriately notified by increasing the speed or the like.

(Embodiment 11)
FIG. 11 is a schematic diagram showing a schematic configuration of the inside of the slave unit 2 from the lateral direction. As shown in FIG. 11, the child device 2 is provided with a heat generating means 15. The heat generating means 15 is composed of a heating wire such as a nichrome wire, and is provided for heating the moisture absorbent 1. When the hygroscopic agent 1 is regenerated by the parent device 4, the temperature can be raised by passing a current from the parent device to the heat generating means. Since the heat generating means is built in the slave unit and the power source is provided in the master unit, the regenerating capacity of the moisture absorbent can be improved without greatly increasing the size of the slave unit.

  In the present embodiment, the heat generating means is installed below the hygroscopic agent 1, but the present invention is not limited to this configuration, and the heat generating means 15 may be installed inside the hygroscopic agent 1. The effect of can be obtained. In addition, by causing the heat generating means 15 to generate heat when the handset 2 is used, a temperature gradient is generated in the air around the handset 2 and it is also possible to obtain an effect as an air circulating means.

(Embodiment 12)
As shown in FIG. 12, the slave unit 2 is provided with a communication means 16 such as wireless communication, and can communicate with the master unit. Since it is assumed that the slave unit is installed in a narrow closed space, a wireless method using radio waves is suitable for communication between the master unit and the slave unit. By performing communication from the child device to the parent device, the operation state of the child device and the surrounding state can be known from the parent device. Specifically, if you can know the information from the handset installed in an invisible position, such as the elapsed time from the start of use of the handset and the change in the humidity of the air around the handset, it can be used effectively. .

  In addition, communication from the master unit to the slave unit and the slave unit generates a notification sound makes it possible to know the location of the slave unit. Specifically, the location of the child device can be recognized by the operation of a speaker as sound generation means of the child device by communication from the parent device. Since it is assumed that the handset is installed in a narrow closed space, there is a possibility of forgetting its existence. In that case, the location of the slave unit can be immediately known by the slave unit emitting a notification sound through communication from the master unit.

(Embodiment 13)
As shown in FIG. 13, the secondary unit 17 is provided in the slave unit 2, and the charging unit 18 is provided inside the master unit 4. The secondary battery 17 may be any battery as long as it can be repeatedly charged and discharged, such as a nickel cadmium battery or a lithium ion battery. In the present embodiment, since the size of the slave unit is desired to be as small as possible, a secondary battery having characteristics of being small and having a large battery capacity is suitable for the secondary battery. The secondary battery 17 is used to operate the above-described air circulation means, display means, various detection means, and the like. Since the child device 2 uses the parent device to regenerate the built-in hygroscopic agent, the secondary battery 17 can be charged by using the charging means 18 provided in the parent device at that time. is there.

  Although the details of the configuration of the secondary battery are not shown, any secondary battery having a battery capacity that can be used to operate the above-described air circulation means, display means, various detection means, etc. The same effect can be obtained even if is used.
