First Embodiment
<< About the dehumidifier >>
First, a dehumidifying device 1 according to a first embodiment of the present invention will be described with reference mainly to FIGS. 1 to 3.
FIG. 1 is a schematic view showing a building 40 equipped with the dehumidifying device 1 according to the first embodiment of the present invention, FIG. 2 is a perspective view showing the dehumidifying device 1, and FIG. 3 is an attachment to the outer wall 40 w of the dehumidifying device 1 It is a typical sectional view showing a state.

The dehumidifying device 1 according to the first embodiment of the present invention includes a cooling unit 20 for dehumidifying (cooling) the air 12 supplied by a blower (ventilating fan 6X), and a drainage unit 21 disposed below the cooling unit 20. And a heater (film heater 3) for heating the heated air 12 by adding heat to the dehumidifying part (cooler 2) integrally formed.
The cooling unit 20 and the heater (film heater 3) are disposed on the flow path of the air 12 supplied to the indoor 15 by a blower (ventilating fan 6X), and the heater (film heater 3) is a dehumidifying unit (cooler 2) Integrally attached to the That is, by integrally attaching the film heater 3 to the cooler 2, it has the portability that it can be carried together.
Here, the flow path of the air 12 supplied to the indoor 15 by the ventilation fan 6X is not limited to the linear extension of the air supply direction of the ventilation fan 6X. For example, when the air 12 passes through a bent conduit (not shown), the curved extension through which the air 12 passes is also included in the flow path.

The dehumidifier 1 has a function of reducing the amount of water vapor in the air 12 by discharging condensation water while lowering the temperature by the cooler 2 and lowering the relative humidity while raising the temperature by the film heater 3. For this reason, the dehumidifying device 1 includes the cooler 2 that lowers the temperature and reduces the amount of water vapor, and the film heater 3 that reduces the relative humidity, so that the sensible temperature is more compared to a fan that lowers the sensible temperature of people. It can be lowered. And according to the dehumidification apparatus 1, it becomes unnecessary to newly provide the air conditioner 8 with large electric power consumption which is shown in FIG. 5 and mentioned later. Details of these configurations will be described later.

As shown in FIG. 1, when the building 40 provided with the dehumidifying device 1 supplies the air 12 from the outdoor 14 to the indoor 15 by the ventilation fan 6X, the air 12 supplied from the dehumidifying device 1 Temperature and humidity are adjusted. In addition, the air 12 in the indoor 15 of the building 40 is configured to be smoothly exchanged by being exhausted to the outdoor 14 by the ventilation fan 6Y.

As shown in FIG. 2 described above, the cooler 2 is integrally formed of a cooling unit 20 for cooling the air 12 supplied to the indoor 15 and a drainage unit 21 disposed below the cooling unit 20. Are configured. That is, the cooler 2 has the portability that the cooling unit 20 and the drainage unit 21 can be carried together.
The cooling unit 20 includes a cooling pipe 20a through which a refrigerant such as cooling water flows, and a frame 20d for holding the cooling pipe 20a.

In the present embodiment, the cooling pipe 20a is connected to a low temperature water source such as a well or a water storage tank (not shown) and a pump (not shown), and is configured to circulate cooling water as a refrigerant. . Thus, according to the cooler 2 by the cooling pipe 20a connected to the water storage tank etc., electric power is more than cooling the indoor 15 by the air conditioner 8 provided with the outdoor unit 8a and the indoor unit 8b described later with reference to FIG. Consumption can be reduced.
The cooling pipe 20a is not limited to the one connected to the well or the water storage tank, but may be connected to a refrigerator equipped with a heat exchanger such as a condenser or an evaporator. It is not limited to water but fluorocarbons etc. may be used.

In the present embodiment, the cooling pipe 20a has a base end side for supplying the cooling water and a tip end side for collecting the cooling water in the short direction of the frame 20d (the main surface 3a of the film heater 3 described later In one direction perpendicular to the direction perpendicular to the frame 20d. In the present embodiment, the “one vertical direction” is a direction extending horizontally and is a direction extending in front of the paper surface shown in FIG. Thus, when the cooling pipe 20a is pulled out from the frame 20d in one direction, piping becomes easy, which is preferable. On the other hand, in the present invention, the direction in which the cooling pipe 20a is drawn out is arbitrary, and may be the vertical direction, and furthermore, the parts of the cooling pipe 20a drawn out from the frame 20d may be mutually different directions.

The cooling pipe 20a is formed so as to be folded back in a plurality of portions at a central portion thereof which is accommodated in the frame 20d. Specifically, as shown in the cross-sectional view in FIG. 3, the cooling pipe 20a according to the present embodiment is formed by being folded back so that four parts are arranged in parallel inside the frame 20d. By forming in this manner, the cooling effect of the air 12 is enhanced by increasing the area in which the air 12 supplied to the indoor 15 contacts the cooling pipe 20 a in the frame 20 d.

The frame 20 d according to the present embodiment has, for example, an inverted U-shaped angled shape viewed from the short direction so that the air 12 can be passed in the short direction (direction perpendicular to the main surface 3 a of the film heater 3 described later). It is formed in the shape of a circle. The lower portion of the frame 20 d is connected so as to be covered by the drainage portion 21.
The drainage portion 21 is for draining condensation moisture falling on the cooling pipe 20a to the outside of the building 40 for dehumidification, and receiving the condensation water dripping from the cooling pipe 20a from below the receiving portion 21a , And a weir 21 b for discharging the dew condensation water to the outside 14.
The receiving portion 21a is formed in a tray shape with a standing wall around the periphery, and is formed to be fitted to the lower portion of the frame 20d.
The weir 21 b is connected to the central lower portion of the receiving portion 21 a so as to be in communication with the internal space thereof, and is in communication with the internal space of the drainage portion 21. The weir 21 b is formed continuously from the indoor 15 to the outdoor 14, and is connected to the drainage pipe 13 provided in the ground of the outdoor 14.

In the dehumidifying device 1 according to the present embodiment, a blower (ventilating fan 6X) for supplying the outside air from the outside 14 to the inside 15 is integrally attached to the cooler 2. The blower (ventilating fan 6X) is, as shown in FIG. 1, an intake-side blower (a pressurized-type blower that pressurizes the indoor 15) that sucks the air 12 from the outdoor (the outdoor 14) to the indoor (the indoor 15). The ventilation fan 6X is configured to be operable by the motor 6c. The ventilation fan 6X includes a mounting frame 6d for mounting on the outer wall 40w, and a rotating shaft 6e rotated by a motor 6c.
In the dehumidifying system of the present invention, as shown in FIG. 1, an exhaust-side fan (ventilating fan 6Y) for exhausting air 12 indoors (indoor 15) to the outdoor (outdoor 14) and an intake-side fan (ventilating fan 6X) And a switch SW that switches the supply of power to simultaneously operate the exhaust side fan (ventilating fan 6Y).
The ventilation fan 6Y has a function of reducing the pressure in the room 15 (indoor), and is provided in a portion of the outer wall 40w of the building 40 apart from the ventilation fan 6X.

Thus, if the ventilation fan 6X and the ventilation fan 6Y are provided in the building 40, ventilation will be performed well between the outdoor 14 and the indoor 15.
By simultaneously operating the ventilation fans 6X and 6Y with the switch SW, the dehumidifying system of the present invention can suppress an increase in the pressure in the room 15 and can satisfactorily supply the air 12 from the ventilation fan 6X.
In addition, if it is a building structure where circulation of air 12 is smooth only by ventilation fan 6X (in other words, if the pressure in indoor 15 can supply air from ventilation fan 6X to indoor 15), ventilation fan 6Y is necessarily required. It is not a configuration.

The mounting frame 6d has, for example, flanges 6a extending upward and downward. The ventilation fan 6X is attached to the outer wall 40w by screwing the set screw 6b into the outer wall 40w through the through hole formed in the flange 6a while the flange 6a is in surface contact with the outer wall 40w. And the cooler 2 is connected to the ventilation fan 6X by the connection frame 4 and the connection pin 4a which are mentioned later, and the film heater 3 which is mentioned later is supported by the cooler 2 by the support 3b. That is, the cooler 2 and the film heater 3 are attached to the outer wall 40w together with the ventilation fan 6X. The shape of the support 3b is not limited as long as the film heater 3 can be supported, and may be a block other than a rod, or a clamp that supports the film heater 3 so as to be held. Alternatively, the film heater 3 may be supported using screws, bolts, nuts, and adhesives.

Depending on the configuration in which the indoor unit 15 is cooled by the air conditioner 8 provided with the outdoor unit 8a and the indoor unit 8b described later with reference to FIG. 5, the dust attached to the filter of the indoor unit 8b is merely diffused. You can not do it.
On the other hand, according to the cooler 2 provided with the ventilation fan 6X according to the present embodiment, the supplied outside air is cooled and taken into the room 15, and the air 12 in the room is exhausted by the ventilation fan 6Y.
Thus, since movement of the air 12 occurs between the indoor 15 and the outdoor 14, dust can be discharged to the outdoor 14 together with the indoor air 12, and the diffusion of dust in the indoor 15 can be suppressed.

The cooler 2 and the ventilation fan 6X are connected by a connecting frame 4.
The connecting frame 4 is formed in a shape substantially identical to the outer shape formed by fitting the frame 20d and the receiving portion 21a and the outer shape of the mounting frame 6d of the ventilation fan 6X excluding the flange 6a.
The ventilation fan 6X and the connection frame 4 are connected by screwing in the connection screw 4b in a state where the end face of the connection frame 4 on the side away from the cooler 2 is superimposed on the attachment frame 6d of the ventilation fan 6X.
The connecting frame 4 and the cooler 2 are a part of the connecting frame 4 and the frame of the cooler 2 in a state where the frame 20 d of the cooler 2 is superimposed on the end face of the connecting frame 4 close to the cooler 2. The connection pin 4a is connected to a part of 20d by being embedded.

The heater according to the present embodiment is a planar (flat) film heater 3 provided with a conductive wire (not shown) therein. Specifically, in the film heater 3 according to the present embodiment, the elements constituting the film heater 3 undergo phase transition according to the temperature, and the electric resistance value changes, so that the heat generation temperature is adjusted. It is a mold heater.
The heater (film heater 3) is disposed on the extension of the air supply direction of the air 12 supplied via the cooling unit 20, and the main surface 3a of the heater (film heater 3) is disposed to face the cooling unit 20.
Here, the extension of the air 12 in the air supply direction is not limited to the linear extension of the air 12 in the air supply direction. For example, when the air 12 passes through a bent conduit (not shown), the bent extension through which the air 12 passes is also included.
Further, “facing” is not limited to the state in which the main surface 3 a of the film heater 3 is disposed parallel to the surface on the indoor 15 side of the cooling unit 20 as shown in FIG. That is, the air 12 passing through the cooling unit 20 may be disposed so as to touch the main surface 3 a, and the main surface 3 a is obliquely directed to the “facing” side with respect to the surface of the cooling unit 20 on the indoor 15 side. The state is also included.

By disposing the film heater 3 in this manner, it is possible to lower the relative humidity while raising the temperature of the air 12 cooled by the cooling unit 20 below the dew point to a suitable temperature for dehumidification. Furthermore, since the main surface 3a of the film heater 3 is disposed to face the cooling unit 20, the dehumidifying device 1 is compactly disposed.
In the present embodiment, the air 12 supplied by the ventilation fan 6X is brought into contact with the flat film heater 3 so as to bypass the film heater 3 and supplied to the indoor 15.

A switch (not shown) for turning on / off power supplied to the film heater 3 may be connected to the film heater 3. By operating the switch connected in this way, for example, when the temperature rise by the film heater 3 interferes with the target temperature setting on summer day, etc., the switch is turned off to operate the film heater 3. You can stop it. Furthermore, the film heater 3 is not limited to the self-control type heater, and may be operation-controlled by another control device, or may be operation-controlled by the operation of the user.

A plurality of through holes may be formed in the thickness direction of the film heater 3 in a region other than the conductive wire (not shown) in the film heater 3. In this way, by passing the air 12 supplied by the ventilation fan 6X through the through hole, the air can be made to go straight without detouring so as to prevent the flow, thereby enhancing the air supply capacity. it can.
In addition, the heater which concerns on this invention is not limited to the planar film heater 3, What is necessary is just to be able to heat up. For example, it may be a steam pipe through which steam for hot water supply passes, or an exhaust heat pipe through which exhaust gas generated by the cogeneration system passes. In this way, it is not necessary to provide separate heaters for the dehumidifier 1.

The dehumidifier 1 further includes a plurality of bar-like supports 3 b for attaching the heater (film heater 3) to the cooler 2. The support 3 b is formed to project toward the film heater 3 from the surface of the cooler 2 facing the film heater 3 in the frame 20 d and the drainage portion 21. The film heater 3 can be easily attached to the cooler 2 by means of the support 3 b.
Therefore, the dehumidifier 1 can easily attach the cooler 2, the film heater 3 and the ventilation fan 6X to the building 40 collectively.

The dehumidifier 1 further includes a generator 5 that generates electric power by rotational power generated by rotation of a rotary shaft 6e of a blower (ventilating fan 6X). And a heater (film heater 3) is using the electric power supplied from the generator 5 as a heat source, and is connected to the generator 5 by the conducting wire 5a. According to such a configuration, it is possible to cause the generator 5 to generate power using the rotational power generated when the ventilation fan 6X operates, and to use the power as a heat source of the film heater 3. Therefore, it is not necessary to separately prepare a heat source for operating the film heater 3.

Preferably, the dehumidifier 1 further comprises a filter 7 for removing foreign matter present in the air.
The filter 7 according to the present embodiment is formed of an antibacterial material or a fiber to which the antibacterial material is applied, and is on the flow path of the air 12 supplied to the indoor 15 and on the upstream side of the fan (ventilating fan 6X) In the mounting frame 6d. On the other hand, as long as it is on the said flow path, the arrangement | positioning is arbitrary, for example, may be provided between a fan (ventilation fan 6X) and a heater (film heater 3).
As described above, the dehumidifier 1 includes the filter 7, so that the air 12 supplied to the indoor space 15 can be cleaned, and adhesion of dust and the like to the film heater 3 can be suppressed.
In addition, when it is not necessary to remove a foreign material, the filter 7 is not necessarily a required structure.

The dehumidifying device 1 preferably further includes a mounting structure (a flange 6 a and a set screw 6 b) to the outer wall 40 w of the building 40.
Specifically, the flange 6 a is a part of the mounting frame 6 d and is formed to project in the vertical direction more than the connecting frame 4. The set screw 6b is inserted through a part of the flange 6a in the thickness direction and screwed into the outer wall 40w. Thus, the dehumidifying device 1 can be easily attached to the inner wall surface of the outer wall 40 w of the building 40 by providing the attaching structure (flange 6 a and the set screw 6 b). In addition, as an attachment structure for attaching the dehumidifier 1 to the outer wall 40w, it is not limited to the thing by the flange 6a and the set screw 6b, You may use a bolt and a nut and an adhesive agent.

Furthermore, when the dehumidifying device 1 is attached to the inner wall surface of the outer wall 40w of the building 40, the air 12 can easily flow around the dehumidifying device 1, and therefore the dehumidifying device 1 is enclosed like a duct (not shown) It can suppress the growth of mold compared to the case of being attached to
However, the dehumidifier according to the present invention is not limited to the one attached to the outer wall 40w, and may be one attached to the duct of the building 40. As described above, when it is attached to the duct, the case where the growth of mold does not become a problem or the case where the duct is already provided and the dehumidifying device is attached to this is easier than attaching to the outer wall 40w, etc. There is.

About the image of the usage example
Images of changes in temperature and humidity when the dehumidifier 1 is used will be described. For example, when the air 12 outside 14 is at a temperature of about 30 degrees and a relative humidity of about 50%, the air 12 supplied by the ventilation fan 6X contacts the cooling unit 20 to a temperature of about 20 degrees and a relative humidity of about 20%. It will be 70%. At this time, since the condensed water is discharged from the weir 21b of the drainage portion 21 to the outside 14, the amount of water vapor in the air is reduced, so that the dehumidified air is dehumidified. Then, by being heated by the film heater 3, the temperature is about 23 degrees and the relative humidity is about 60%, and the air 12 of this temperature and the relative humidity is supplied to the indoor 15.
Regarding the temperature of the cooling water flowing through the cooling pipe 20a of the cooler 2, the temperature of the cooling water flowing from the water storage tank or the like into the cooling unit 20 (frame 20d) is approximately 7 to 10 degrees, and the cooling unit 20 returns to the water storage tank or the like The temperature of the incoming cooling water is about 15 degrees. Then, for example, when the dehumidifier 1 is used for 10 hours, the amount of water discharged to the outside 14 is about 15 liters.
As described above, by bringing the air 12 outside 14 into contact with the cooling unit 20, it is possible to lower the temperature to cause condensation and reduce the amount of water vapor in the air for dehumidification. Further, the film heater 3 can lower the relative humidity by lowering the relative humidity while raising the supplied air 12 to an appropriate temperature at which the user does not feel cold.

Unlike the cooler 2, the cooler 2X is directly attached to the outer wall 40w, not to the outer wall 40w (see FIG. 3) via the ventilation fan 6X. Specifically, the upper portion of the frame 20Xd of the cooling unit 20X constituting the cooler 2X and the lower portion of the frame 21Xd of the drainage portion 21X extend on the side (the outer wall 40w side) away from the film heater 3. At the extended end, the flanges 20b extend in the directions away from each other, upper and lower directions which are perpendicular to the extending direction.

The cooler 2X is attached to the outer wall 40w by screwing the set screw 20c into the outer wall 40w through the through hole formed in the flange 20b with the flange 20b in surface contact with the outer wall 40w. Become. And since the film heater 3 is supported by the cooler 2X by the support 3b, these are attached to the outer wall 40w with the cooler 2X.

The cooler 2X configured in this way can dehumidify the supplied air 12 by being attached to the downstream side of the supplied air 12 by the existing ventilation fan (not shown). For this reason, it is not necessary to newly prepare a ventilation fan, and it can hold down cost.

In addition, although the connection part 9 which concerns on said dehumidifier 1Y illustrated the structure which connects the cooling part 20Y (heat exchanger 10) and the indoor unit 8b (heat exchanger 8ba) in parallel, this invention is such It is not limited to the following configuration.
For example, the refrigerant pipe 8 d and the connection portion 9 may be disposed so as to be connected in series with the cooling unit 20 Y (heat exchanger 10) and the indoor unit 8 b (heat exchanger 8 ba). In this case, it is preferable that the refrigerant supplied from the outdoor unit 8a is configured to pass through the cooling unit 20Y (the heat exchanger 10) earlier than the indoor unit 8b.
In this case, specifically, one portion of the refrigerant pipe 8d through which the refrigerant supplied to the living room 40b passes is connected to the outdoor unit 8a and the cooling unit 20Y. The connection part 9 through which the refrigerant supplied to the living room 40a passes is connected to the cooling part 20Y and the indoor unit 8b. Further, the other part of the refrigerant pipe 8d is connected to the indoor unit 8b and the outdoor unit 8a.
With such a configuration, since the amount of heat absorption by the cooling unit 20Y for dehumidification is small, the refrigerant after passing through the cooling unit 20Y can be effectively used for cooling the living room 40a by the indoor unit 8b.

In the above embodiment, although an example of attaching the dehumidifying device to the outer wall has been described, the present invention is not limited to such a configuration, and is attached to a wall, a ceiling plate, a bottom plate, etc. It is also good. For example, when the dehumidifying device is attached to the ceiling plate or the bottom plate, the dehumidifying device may be attached such that the dehumidifying device is disposed on the flow path of the air 12 supplied in the downward or upward direction. Specifically, the dehumidifier may be rotated 90 degrees and attached such that the film heater 3 is positioned closer to the air supply side than the cooler 2 with respect to the attachment direction of the dehumidifier according to the above embodiment.

The end portions 52f of the side edge portions on the other side of the first portion 52a and the second portion 52b are spaced apart and spaced apart. A gap provided between the end 52f of the side edge on the other side is an indoor side opening for supplying air into the room, and is a slit 52e formed along the longitudinal direction of the mantle 52.
Specifically, the end 52 f of each of the first portion 52 a and the second portion 52 b is formed so as to be folded back to the axial center side from another portion extending in the circumferential direction of the mantle 52 .
The protruding length of the folded back portion and protruding from the other portion is longer than the total thickness of the first moisture absorbent 50 (or the second moisture absorbent 60) and the first heater 51 (or the second heater 61).
In this manner, the end 52 f is folded back and protrudes, thereby limiting the deviation in the circumferential direction of the first moisture absorber 50 (or the second moisture absorber 60) and the first heater 51 (or the second heater 61). Can.

In the outer collar portion 52, an indoor side opening (slit 52e) and an outdoor side opening 52d (see FIG. 10) continuous with the indoor side opening (slit 52e) via the accommodation space 52c are formed.
The slit 52e is formed on the side wall of the outer collar 52, and the outdoor opening 52d is a proximal end (an end on the support box 54 side) of the outer collar 52 continuous with the accommodation space 52c. A lid 57 is attached to the tip of the mantle 52, and the tip of the mantle 52 is sealed by the lid 57.

As described above, the outer cover 52 is formed to be long, and the indoor opening is the slit 52 e, so that the moisture absorbent (the first moisture absorbent 50 or the second moisture absorbent) disposed in the inside of the outer pocket 52 The air dehumidified by the hygroscopic material (the first hygroscopic material 50 or the second hygroscopic material 60) can be effectively supplied to the room while increasing the area of the air touched by 60).

The indoor side opening (slit 52e) has a heater (first heater 51 or second heater 61) and a hygroscopic material (first hygroscopic material 50 or second hygroscopic material 60) in a cross section orthogonal to the longitudinal direction of the mantle 52 Are formed on extensions of the openings 51a, 50a at the end of the arc shape in each of.
In the present embodiment, the slits 52e have openings 51a between the end portions on the other side of the two first heaters 51 (two second heaters 61) in the vertical cross section shown in FIG. It is formed on the extension of the opening 50a between the end parts on the other side of the sheet of the first moisture absorbing material 50 (the two sheets of the second moisture absorbing material 60). And the slit 52e has an opening 51a between the end portions on the other side of the two first heaters 51 (two second heaters 61), and the two first moisture absorbents 50 (two The second moisture absorbent material 60) is formed so as to be narrower and open in the circumferential direction of the outer collar 52 than the opening 50a between the end portions on the other side.

When the air dehumidified by the hygroscopic material (the first hygroscopic material 50 or the second hygroscopic material 60) is supplied into the room by being formed in this manner, the heater (the first heater 51 or the second heater 61) When exhausting the air heated by (1) from the room to the outside, it is possible to suppress interference between the moisture absorbent and the heater and to suppress the decrease in the amount of ventilation.
The present invention is not limited to such an embodiment, and the slits 52e may be formed of the first heater 51 (or the second heater 61), and the first moisture absorbent material 50 (so that the restriction of the air flow rate can be suppressed). Alternatively, it may be formed on the extension of the opening at the other end of the second moisture absorbent material 60). Specifically, the first heater 51 (or the second heater 61) and the first hygroscopic material 50 (or the second hygroscopic material 60) are not provided two each, but are integrally formed. It is also good. Even in such a case, the first heater 51 (or the second heater 61) and the first hygroscopic material 50 (or the second hygroscopic material 60) are provided with openings so as not to interfere with the air flow to the slits 52e. It should just be.

When the first heater 51 (or the second heater 61) and the first moisture absorbing material 50 (or the second moisture absorbing material 60) are respectively integrally formed, the first portion 52a and the second region 52 of the mantle 52 are It is necessary not to inhibit the opening / closing by the hinge 53 with the site 52b.
For example, the end 52f of the first portion 52a and the second portion 52b is at the end of the first heater 51 (or the second heater 61) and the end of the first moisture absorbing material 50 (or the second moisture absorbing material 60) It may be formed flat, without forming in the axial center side so that it may not contact | abut.
In addition, the first portion 52a and the second portion 52b are not opened and closed by the rotation around the rotation shaft 53a by the hinge 53, but the first peripheral portion of the lid 57 and the other not-shown fitting portions are used. The portion 52a and the second portion 52b may be configured to be vertically fitted.

[Supporting box]
The mantle 52 according to the present embodiment is supported at its base end side by a support box 54 shown in FIGS. 9 and 10. The support box 54 is formed in a box-like box main body 54 a, a lid 54 b for closing the box main body 54 a, and a hollow substantially rectangular parallelepiped shape.
As shown in FIG. 10, the side wall 54e of the box body 54a is formed with a through hole 54d through which the base end of the outer collar 52 passes, and a boss 54c is formed inside the box body 54a at the periphery of the through hole 54d. It is formed to protrude. That is, the base end of the mantle 52 is supported by the boss 54c.

For example, assuming that the curvature of the outer surface of the mantle 52 in the natural state is smaller than the curvature of the supporting surface of the boss 54c, the boss 52c is deformed by the reaction force of the boss 54c against the restoring force of the mantle 52. It is possible to support suitably by. According to such a configuration, the outer collar 52 can be fitted and supported by the boss 54 c without providing a separate attachment member.
Of course, it is also possible to attach the shell 52 to the box body 54a by a separate attachment member.

Further, a through hole 54g for communicating the inside of the box body 54a with the outside through the cylindrical communication cylinder 55 shown in FIG. 9 in the bottom wall portion 54f opposed to the lid 54b in the box body 54a (see FIG. 10) Is formed. The unshown internal flange portion provided at the end of the communication cylinder 55 shown in FIG. 9 is assembled with a screw or the like in a state of being in contact with the periphery of the through hole 54g, the communication cylinder 55 and the box main body 54a Is connected.
A disc-like flange 56 to which the first fan 58 (or the second fan 68) is attached is provided at the outdoor end of the communication cylinder 55.

The ventilator with dehumidification function S1 according to the present embodiment includes a humidity sensor 73 that detects the humidity of the air supplied to the room from outside (in the present embodiment, the air inside the communication cylinder 55).
The humidity sensor 73 is used to calculate the amount of moisture absorption of a first moisture absorbent material 50 (second moisture absorbent material 60) described later, and is attached to the inner wall surface of the communication cylinder 55.
The humidity sensor 73 may be disposed inside the support box 54 or inside the outer casing 52 as well as inside the communication cylinder 55. This is because it is only necessary that the correlation between the magnitude of the humidity of the air supplied from the outdoor can be calculated by the control unit C described later.
The moisture absorption amount may be calculated by another method as described later without using the humidity sensor 73.
In the present embodiment, an example in which the hygroscopic material and the heater are provided only in the inside of the mantle 52 is described, but for example, the hygroscopic material may be provided inside the support box 54 and the communication cylinder 55 as well. The heater may be further provided.

[Blower]
The blowers are a first blower (first fan 58) attached to the first air conditioner S11 to be unitized, and a second blower (second fan 68 attached to the second air conditioner S12 to be integrated And is included.
Specifically, each of the first fan 58 and the second fan 68 is attached to the flange 56 provided on the communication cylinder 55 as shown in FIGS. 6 and 9 and described above. The flange 56 also functions as a mounting portion for mounting the first air conditioner S11 (second air conditioner S12) on the wall of the room.
And 1st air conditioning apparatus S11 and 2nd air conditioning apparatus S12 have a flange 56 as an attaching part, respectively, and a room as a unit with a fan (the 1st fan 58 or the 2nd fan 68) It can be easily attached to the wall of the
The "attachment portion" attached to the wall of the room is not limited to the flange 56, but may be the support box 54, the communication cylinder 55, etc., and a fixture (not shown) attached to these. It is also good.

In addition, since the blowers are individually attached to the first air conditioner S11 and the second air conditioner S12, a stable air volume can be secured in each device, and both of the dehumidifying ability and the recovery ability can be obtained. It is preferable in that it can be enhanced.
However, the present invention is not limited to such a configuration as long as it is possible to form flow paths in the opposite direction with respect to the indoor and the outdoor in the first air conditioner S11 and the second air conditioner S12. That is, the first air conditioning apparatus S11 and the second air conditioning apparatus S12 do not necessarily have to be provided with a blower separately, and even if the blower is provided indoors or only one is required. Good.

[Control unit]
Next, a control method of the first air conditioning apparatus S11, the second air conditioning apparatus S12, and the first fan 58 and the second fan 68 by the control unit C will be described mainly with reference to FIGS. FIG. 11 is a diagram showing a control flow of the dehumidifying function-equipped ventilator S1 (first air conditioner S11, second air conditioner S12, and first fan 58 and second fan 68) by the control unit C. Fig.12 (a) is a figure which shows the moisture absorption amount of the 1st moisture absorbing material 50 in 1st air conditioning apparatus S11, and the relationship of time, FIG.12 (b) is the 2nd moisture absorbing material 60 in 2nd air conditioning apparatus S12. It is a figure which shows the relationship between moisture absorption amount and time.

For the sake of convenience, in FIGS. 12 (a) and 12 (b), the diagram of the amount of absorbed moisture (wt%) starts at 0. However, the actual value of the moisture absorption amount (wt%) 0 in FIG. 12 is not the factory shipment value of the first moisture absorbing material 50 and the second moisture absorbing material 60, but the value of the first moisture absorbing material 50 and the second moisture absorbing material 60. It shows the value of the lower limit of the amount of moisture absorption (wt%) in the environment being used. That is, the value of the moisture absorption amount (wt%) 0 is a value higher than the value at the time of shipment from the factory, and the value after recovery control after repeatedly using the first air conditioner S11 or the second air conditioner S12 equal.
The control unit C controls the first air conditioner S11, the second air conditioner S12, and the first fan 58 and the second fan 68 according to the operation of a person (user) and / or automatically. It is a thing.

The control unit C drives the first fan 58 attached to the first air conditioner S11 and the second fan 68 attached to the second air conditioner S12 when the control start operation is performed by the operation of a person. To do (step S1).
Specifically, assuming that the rotation forming the air flow in the air supply direction to the room is the first rotation, and the rotation forming the air flow in the air discharging direction to the outside is the reverse rotation. When the first fan 58 is rotated in the forward direction, the second fan 68 is controlled to rotate in the reverse direction.
By controlling in this manner, it is possible to let the outside air from the outside of the room pass through the room and be discharged to the outside.
Furthermore, the control unit C operates the second heater 61 of the second air conditioner S12.

Here, the control for taking the dehumidified outside air into the room by positively rotating the first fan 58 or the second fan 68 without operating the heater (the first heater 51 or the second heater 61) is referred to as "dehumidification control". . That is, the control unit C performs dehumidification control on the first air conditioner S11.
In addition, the heater (the first heater 51 or the second heater 61) is operated to evaporate the moisture absorbed by the first moisture absorbing material 50 or the second moisture absorbing material 60 to recover the dehumidifying function. " This control involves control of discharging the moisture-containing air to the outside by reversely rotating the first fan 58 or the second fan 68. That is, the control unit C performs recovery control on the second air conditioner S12.
At the beginning of the operation start of the first air conditioner S11 and the second air conditioner S12, that is, at the stage before the dehumidification control, the moisture absorbed by the first moisture absorbing material 50 or the second moisture absorbing material 60 is small. Therefore, at this stage, the operation of the heater (the first heater 51 or the second heater 61) is optional.

Next, the control unit C determines the characteristics (hygroscopic efficiency) of the hygroscopic material (the first hygroscopic material 50 or the second hygroscopic material 60), the humidity data of air passing through the communication cylinder 55 detected from the humidity sensor 73, and the control unit The moisture absorption amount of the moisture absorbent material (the first moisture absorbent material 50 or the second moisture absorbent material 60) assumed from the aeration time measured by the timer provided to C is calculated (step S2).
For example, when the moisture absorption amount of the moisture absorbing material (the first moisture absorption material 50) is equal to or less than a prescribed amount (60 wt% of the moisture absorption possible amount in the present embodiment) (step S3: No), the control unit C calculates the moisture absorption amount (Step S2).
On the other hand, the control unit C is a predetermined threshold whose absorption amount of the hygroscopic material (the first absorption material 50) is less than the hygroscopic amount, and which is 50 wt% or more of the hygroscopic amount (this In the embodiment, when it exceeds 60 wt%, that is, when the value exceeds the prescribed amount (step S3: Yes), dehumidifying control and recovery control for the first air conditioner S11 and the second air conditioner S12. And (step S4). For example, the threshold is 60 wt% or 70 wt% of the hygroscopic capacity.

Specifically, the control unit C switches the rotation of the first fan 58 from the forward rotation to the reverse rotation (step S4), drives the first fan 58 (step S1), and the first air conditioner S11 It switches so that 1 heater 51 may be operated (Step S4). At the same time, the control unit C switches the rotation of the second fan 68 from the reverse rotation to the positive rotation, drives the second fan 68 (step S1), and operates the second heater 61 of the second air conditioner S12. It is stopped (step S4). Furthermore, when the dehumidification control and the recovery control are switched, the measurement of the aeration time by the timer is restarted in order to calculate the moisture absorption amount of the second moisture absorbent material 60 of the second air conditioner S12.
Thereafter, the control unit C alternately performs the dehumidifying control and the recovery control on the first air conditioner S11 and the second air conditioner S12 in parallel until the control is canceled by the operation of the control unit C by the user. Run.
With such control, as shown in FIG. 12, it is possible to suppress the decrease in the dehumidifying efficiency of each of the first moisture absorbent 50 of the first air conditioner S11 and the second moisture absorbent 60 of the second air conditioner S12. The dehumidified air can be continuously and stably taken into the room.

FIG. 12B shows a state in which the second heater 61 is operated at the time of operation of the first second fan 68. In this case, since the moisture absorbed by the second moisture absorbing material 60 is vaporized by the second heater 61, the moisture absorption amount remains at 0 wt% until the control is switched to the dehumidification control.
For example, when the second heater 61 is not operated at the time of the first operation of the second fan 68, air containing moisture in the room comes in contact with the second moisture absorbent material 60 of the second air conditioner S12, and from inside the room The amount of moisture absorbed by the second moisture absorbing material 60 slightly increases because the fluid flows out of the room. The change in the amount of moisture absorption after the start of recovery control for the second moisture absorbent material 60 (that is, after 2 hours shown in FIG. 12B and thereafter) is similar to that shown in the schematic diagram 12 (b).

In addition, the control unit C may have a function of controlling the supplied power for heating the heater (the first heater 51 or the second heater 61). Specifically, at the time of recovery control, when the humidity detected by the humidity sensor 73 is high, the control unit C performs control to increase the supplied power more than when the detected humidity is low.
According to such a configuration, when the humidity of the outside air taken into the room through one of the first air conditioning apparatus S11 or the second air conditioning apparatus S12 is high, the hygroscopic material (the first moisture absorption material 50 or the second moisture absorption material) The moisture absorption of 60) increases quickly. In this case, the efficiency of recovery control in the other of the first air conditioner S11 or the second air conditioner S12 can be enhanced by increasing the power supplied to the heater, and the amount of dehumidification by the dehumidification control and the recovery control Balance of recovery amount can be maintained.
That is, in recovery control, the amount of moisture released from the first moisture absorbing material 50 or the second moisture absorbing material 60 can be increased by the heat of the heater to which large power is supplied, and recovery control to dehumidification control with a small amount of moisture absorption. It can be migrated. Therefore, it is possible to efficiently dehumidify the room while suppressing the control failure by reducing the number of switching of the dehumidification control and the recovery control. On the other hand, when the humidity of the outside air is low, energy saving can be achieved by relatively reducing the power supplied to the heater.

First Modified Example
Although the 1st moisture absorption material 50 and the 2nd moisture absorption material 60 which concern on the said embodiment were demonstrated as what does not have an unevenness | corrugation, this invention is not limited to such a structure.
Next, a hygroscopic material 80 according to a first modification will be described mainly with reference to FIG. FIG. 13 is a schematic longitudinal sectional view showing a moisture absorbent material 80 according to a first modification.
The moisture absorbent material 80 is formed in a sheet shape in a long shape.
The hygroscopic material 80 is formed of a main body portion 80a which is a cylindrical base portion, and a protrusion 80b which is formed continuously projecting from the inner surface of the main body portion 80a in order to enhance the dehumidifying efficiency and the dehumidifying efficiency. There is. In other words, the inner surface of the moisture absorbent material 80 has a plurality of ridges 80b formed in an annular shape as viewed in the longitudinal direction in the longitudinal direction.
A vent (not shown) communicating the inside with the outside is formed in a portion of the moisture absorbing material 80 opposite to the slit 52 e of the mantle 52.

According to the hygroscopic material 80 provided with such ridges 80b, the contact area with the air passing through the hygroscopic material 80 can be made larger than that formed flat without unevenness.
Therefore, as described above, the ability to increase the dehumidification efficiency of the hygroscopic material 80 can effectively suppress the supply of air with high humidity into the room, and can increase the dehumidification efficiency. The dehumidifying ability can be recovered quickly. Furthermore, the flow of air passing through the inside of the moisture absorbent material 80 is disturbed by coming into contact with the ridges 80b, and the moisture absorption rate and moisture release rate can be increased.
Furthermore, the hygroscopic material 80 is not limited to one including the cylindrical main body 80a, and, like the first hygroscopic material 50 or the second hygroscopic material 60 shown in FIG. Alternatively, a main body portion formed separately may be provided as a base portion. In this case, the protrusion 80b is formed in an arc shape in cross section when viewed in the long direction.

Second Modified Example
Although the mantle 52 according to the above embodiment has been described as extending linearly in the longitudinal direction, the present invention is not limited to such a configuration.
Next, a mantle 82 according to a second modification will be described with reference to FIG. FIG. 14 is a schematic vertical cross-sectional view showing a mantle 82 having the first moisture absorbent 50 and the first heater 51 therein according to a second modification.
The outer collar portion 82 is formed to have large diameter portions and small diameter portions alternately in the longitudinal direction while having a substantially uniform thickness. Then, the first heater 51 having a substantially uniform thickness is attached along the inner wall surface of the outer sheath portion 82, and the first moisture absorbent material 50 formed into a sheet shape with a substantially uniform thickness is a first heater It is stuck on top of 51. Further, a cosmetic cylinder 89 is provided so as to cover the outer peripheral surface of the outer collar portion 82. The cosmetic cylinder 89 is preferable because the appearance can be improved, but the cosmetic cylinder 89 is not necessarily a necessary component.

The inner surface of the first moisture absorbent 50 configured in this manner has a plurality of ridges formed in an annular or arc shape in the longitudinal direction when viewed in the longitudinal direction.
For this reason, the first moisture absorbent material 50 disposed along the inner wall surface of the outer collar portion 82 is the first moisture absorbent material 50 disposed along the inner wall surface of the flat outer rib portion 52 having no unevenness. Compared to the above, the contact area with air passing through the inside of the hygroscopic material 50 can be increased.
Therefore, the ability to increase the dehumidifying efficiency of the hygroscopic material 50 can effectively suppress the supply of air with high humidity into the room, and the ability to increase the dehumidifying efficiency enables the dehumidifying ability to be reduced. It can recover quickly. That is, also in the second modification, the same effect as the first modification can be obtained.

In the second modification, although the first air conditioning apparatus including the first moisture absorbent 50 and the first heater 51 as constituent members has been described, it goes without saying that the same configuration can be adopted for the second air conditioning apparatus. is there.
For example, when the humidity of the outdoor air (outside air) facing one side of the first air conditioner and the second air conditioner is constantly higher than the humidity of the outside air of the other side, the one air conditioner However, the other air conditioner may be provided with the mantle 52 shown in FIG. 9. In this way, it is possible to maintain a balance between the amount of dehumidification by the dehumidification control of the first air conditioner or the second air conditioner and the amount of recovery by recovery control.
That is, air conditioners having different dehumidification capabilities may be provided according to the humidity of the outside air.

Third Modified Example
In the above embodiment, as shown in FIG. 9, the outer collar portion 52 is described as having no pattern and the support box 54 has a rectangular shape, but the present invention relates to such a configuration. It is not limited to things.
Next, a first air conditioning apparatus S21 according to a third modification will be described with reference to FIG. FIG. 15 is a schematic perspective view showing a first air conditioning apparatus S21 according to a third modification.
The first air conditioning apparatus S21 includes an outer collar 92 with a pattern 92f and a hollow hemispherical support box 94.

In the mantle 92, a plurality of patterns 92f, which are hollows with a star-shaped bottom, are formed. The design is enhanced by the pattern 92f. Further, as the pattern 92f, the outer collar 92 may be a through hole penetrating in the thickness direction, and air may flow between the inside and the outer of the outer collar 52 also in the pattern 92f.

The support box 94 is formed so that the side attached to the wall surface in the room has a flat surface, and the indoor side is formed in a bowl shape and formed in a hemispherical shape.
In particular, when the support box 94 is formed to have a uniform (including substantially uniform) thickness and the inner surface is also formed in a hemispherical shape, the air introduced into the support box 94 is applied to the hemispherical inner surface. It can be made to contact and it can guide | induce to the outer collar part 92 or the communication cylinder 55 side. Therefore, air can be efficiently supplied from the outside to the room, and the air can be efficiently discharged from the room to the outside.

In addition, by combining the star-shaped pattern 92f and the hemispherical support box 94, it is possible to express a star on the near side by the support box 94 and a distant star by the pattern 92f, and the first air conditioner S21 relates to the star sky as a whole. It is possible to create a sense of unity beauty.
In addition, in the 3rd modification, although 1st air conditioning apparatus S21 was demonstrated to the example, it is needless to say that the same structure can be employ | adopted also about a 2nd air conditioning apparatus.

Fourth Modified Example
In the above embodiment, the control unit C (refer to FIG. 6) measures the moisture absorption amount of the moisture absorbent (the first moisture absorbent 50 or the second moisture absorbent 60), the characteristic of the moisture absorbent, the humidity data by the humidity sensor 73, and the control unit It demonstrated as what was calculated by the ventilation time measured by the timer provided in C. FIG. However, the present invention is not limited to such a configuration.
Next, a configuration according to a strain sensor 74 according to a fourth modification will be described mainly with reference to FIGS. 16 and 17. FIG. 16 is a schematic perspective view showing a state in which the strain sensor 74 according to the fourth modification is attached in the vicinity of the outdoor side opening 52 d in the mantle 52. FIG. 17 is a diagram showing a control flow of the dehumidifying function-equipped ventilator S1 by the controller C according to the fourth modification.

The first moisture absorbing material 50 (or the second moisture absorbing material 60) provided in the inside of the outer collar 52 becomes heavier by the amount of the adsorbed water when the moisture in the air is adsorbed. The outer collar 52 is supported at its proximal end on the outdoor side opening 52 d side in a cantilevered manner by a support (boss 54 c). Therefore, as the first moisture absorbing material 50 becomes heavier, the load is applied to the upper portion of the boss 54c from the upper portion of the proximal end portion of the outer collar portion 52 with the lower portion of the boss 54c in contact with the lower portion of the base end portion Will be added. At this time, the base end of the mantle 52 receives a reaction force from the upper portion of the boss 54 c, and a bending moment is applied to the base end of the mantle 52.
The strain sensor 74 is attached to an inner surface of a portion (a supported portion) of the base end portion of the outer collar portion 52 that abuts on the upper portion of the boss 54c. For this reason, the strain sensor 74 can detect a minute amount of deflection of the base end portion of the mantle 52 due to a bending moment which varies with the amount of moisture absorption.

Then, the control unit C calculates the amount of increase in the weight of the first moisture absorbing material 50 from the amount of slight deflection of the base end of the mantle 52 detected by the strain sensor 74, and calculates the moisture absorption of the moisture absorbing material. Control can be performed as follows. Among the control shown next, step S11 is substantially the same as step S1 described with reference to FIG. 11, step S13 is step S3, and step S14 is step S4, so duplicate contents will be described. I omit explanation.

Furthermore, the control unit C operates the second heater 61 of the second air conditioner S12.
Next, the control unit C calculates the moisture absorption amount of the moisture absorbent (the first moisture absorbent 50 or the second moisture absorbent 60) based on the deflection amount detected by the strain sensor 74 (step S12).
For example, when the moisture absorption amount of the moisture absorbing material (the first moisture absorption material 50) is equal to or less than a prescribed amount (60 wt% of the moisture absorption possible amount in the present embodiment) (step S13: No), the control unit C calculates the moisture absorption amount (Step S12).
On the other hand, the control unit C is a predetermined threshold whose absorption amount of the hygroscopic material (the first absorption material 50) is less than the hygroscopic amount, and which is 50 wt% or more of the hygroscopic amount (this In the embodiment, the dehumidification control for the first air conditioner S11 and the second air conditioner S12 is performed when the amount of moisture absorption exceeds 60 wt%), that is, when the value exceeds the prescribed amount (step S13: Yes) And recovery control (step S14).
According to such a configuration, it is not necessary to perform the measurement by the timer which is necessary in the control according to the above-described embodiment, and it is not necessary to synchronize the start of ventilation to the first moisture absorbent 50 and the start of measurement of the timer. It is possible to preferably switch between dehumidification control and recovery control.

It has been described that switching of control is simultaneously performed.
However, the present invention is not limited to such a configuration. Next, control by the control unit C according to the fifth modification will be described mainly with reference to FIG. FIG. 18 is a diagram showing a control flow of the dehumidifying function-equipped ventilator S1 by the control unit C according to the fifth modification.

The control unit C according to the fifth modification stops the heater (the first heater 51 or the second heater 61) when switching from recovery control to dehumidification control, and is a hygroscopic material in which air from the room is heated by the heater Ventilation control is performed to operate the blower (the first fan 58 or the second fan 68) so as to contact the (first moisture absorbent 50 or the second moisture absorbent 60) and flow out to the outside.
Specifically, as shown in FIG. 18, when the control start operation is performed by a person's operation, the control unit C performs the first fan 58 attached to the first air conditioner S11, and the second air conditioner The second fan 68 attached to S12 is driven (step S21). Furthermore, the control unit C operates the second heater 61 of the second air conditioner S12.
Next, the control unit C calculates the amount of moisture absorption of the moisture absorbent (the first moisture absorbent 50 or the second moisture absorbent 60) based on the amount of deflection detected by the strain sensor 74 (step S22).
When the moisture absorption amount of the moisture absorbing material (the first moisture absorbing material 50) becomes a value exceeding the prescribed amount (60 wt% of the moisture absorption possible amount in the present embodiment) (step S23: Yes), the controller C controls the second heater The operation of 61 is stopped (step S24). The state is maintained without switching between the dehumidifying control and the recovery control until the predetermined time when the second heater 61 stops taking heat (until 5 minutes in this embodiment) (ventilation control) Say.). After the predetermined time has elapsed (step S25), the dehumidifying control and the recovery control for the first air conditioner S11 and the second air conditioner S12 are switched (step S26).

Specifically, the control unit C switches the rotation of the first fan 58 from the forward rotation to the reverse rotation (step S26), drives the first fan 58 (step S21), and the first air conditioner S11 It switches so that 1 heater 51 may be operated (Step S26). At the same time, the control unit C switches the rotation of the second fan 68 from reverse rotation to forward rotation, and drives the second fan 68 (step S21).

According to the above-described control, heat is applied by passing through the second heater 61 in order to maintain the state in which the second fan 68 ventilates the air in the room until the second heater 61 does not take heat. Air can be prevented from being supplied into the room. Therefore, the temperature rise in the room can be suppressed.
Note that the operation using the heater (the first heater 51 or the second heater 61) is stopped for the control using the humidity sensor 73 described with reference to FIG. 11 instead of the control using the strain sensor 74. It is of course possible to apply control to put
