Japanese Patent Application Publication No. 9-060958 Japanese Patent Application Publication No. 4-240345

Although the technique disclosed in Patent Document 1 suppresses dew condensation on the frame, there is still room for improvement in order to further suppress dew condensation.

The present invention takes the above-mentioned facts into account and aims to suppress condensation at the air terminal.

The air outlet according to the first aspect includes a frame frame and a rectifying plate provided within the frame frame, and at least one of the frame frame and the rectifying plate has a hygroscopic heat generating material containing a hygroscopic heat generating fiber. .

According to the air terminal according to the first aspect , the air terminal includes a frame and a rectifying plate provided within the frame. At least one of the picture frame and the current plate has a moisture-absorbing heat-generating material containing moisture-absorbing heat-generating fibers. As a result, for example, when dew condenses on the picture frame and the rectifying plate, the condensation is absorbed (adsorbed) by the hygroscopic heat generating fibers of the hygroscopic heat generating material. Therefore, dew condensation on the picture frame and the current plate is suppressed.

In addition, the moisture-absorbing heat-generating fiber generates heat when it absorbs dew condensation. This increases the temperature of the frame frame and the current plate, making it difficult for dew condensation to occur on the frame frame and the current plate. Therefore, dew condensation on the picture frame and the current plate is further suppressed.

The air terminal according to the second aspect is the air terminal according to the first aspect , in which the moisture absorbing heat generating material is provided on the picture frame and the rectifying plate located on the inner peripheral part of the picture frame.

According to the air outlet according to the second aspect , the moisture absorbing heat generating material is provided in the picture frame and the rectifying plate located on the inner peripheral part of the picture frame.

Here, for example, when cold air is blown into the room from the air outlet, the warm air in the room flows as the cold air is blown out, and the warm air flows into the picture frame and the inner peripheral part of the picture frame. Therefore, dew condensation is likely to occur on the picture frame and the rectifier plate located on the inner circumference of the picture frame.

On the other hand, in the present invention, the moisture-absorbing heat generating material is provided on the picture frame and the rectifying plate on the inner peripheral part of the picture frame. Thereby, it is possible to efficiently suppress dew condensation on the picture frame and the rectifier plate located on the inner peripheral part of the picture frame.

In the air outlet according to the third aspect , in the air outlet according to the first aspect or the second aspect, the moisture absorbing heat generating material is provided along one side surface of the current plate.

According to the air outlet according to the third aspect , the moisture absorbing heat generating material is provided along one side of the current plate.

Here, as described above, the moisture-absorbing heat-generating material generates heat when it absorbs moisture from the condensation on the rectifier plate. As a result, one side surface of the current plate is heated, so that dew condensation on the side surface is suppressed. Further, the heat of the moisture absorbing heat generating material is transmitted from one side of the current plate to the other side of the current plate. Therefore, dew condensation is suppressed not only on one side of the current plate but also on the other side of the current plate.

Therefore, in the present invention, compared to the case where the moisture absorbing heat generating material is provided along both sides of the current plate, it is possible to suppress dew condensation on the current plate and reduce the material cost of the moisture absorbing heat generating material.

As explained above, according to the air termination port according to the present invention, dew condensation on the air termination port can be suppressed.

Hereinafter, an air terminal according to an embodiment will be described with reference to the drawings.

(Air terminal)
FIG. 1 shows an air termination port 20 according to this embodiment. As shown in FIG. 2, the air outlet 20 is an outlet that blows out air-conditioning air (cold air or warm air) into the room 10. The air outlet 20 is provided in an opening 14 formed in the ceiling 12.

A duct 16 provided on the back side of the ceiling 12 is connected to the air outlet 20. An air conditioner (not shown) is connected to the duct 16. Thereby, the air-conditioning air (cold air or warm air) generated by the air conditioner is blown into the room from the air outlet 20 via the duct 16.

As shown in FIGS. 1 and 2, the air terminal 20 is H-shaped or V-shaped. The air outlet 20 includes a frame frame 22, a rectifying plate 26, and moisture-absorbing heat-generating materials 30, 40.

(Picture frame)
The picture frame 22 is formed into a rectangular frame shape from metal, resin, or the like. Further, the frame frame 22 is arranged along the outer periphery of the opening 14 formed in the ceiling 12, and is fixed to the ceiling 12 with screws, adhesives, etc. (not shown).

As shown in FIG. 2, the frame frame 22 has a plurality of (four in this embodiment) frame parts 24. Each frame portion 24 is formed to have an L-shaped cross section. This frame portion 24 has a side wall portion 24A and a frame portion 24B.

The side wall portion 24A is disposed within the opening 14 of the ceiling 12 and is connected to the duct 16. A frame portion 24B is provided at the end portion (tip portion) of the side wall portion 24A on the opening 14 side. The frame portion 24B extends outward along the lower surface of the ceiling 12 from the end of the side wall portion 24A on the opening 14 side. Note that each frame portion 24 is provided with a moisture absorbing heat generating material 30, which will be described later.

(rectifier)
As shown in FIG. 1, the plurality of rectifying plates 26 are arranged inside the picture frame 22. Further, the plurality of rectifying plates 26 are formed into a plate shape from metal, resin, or the like. These rectifier plates 26 are arranged along the vertical width direction (arrow Y direction) of the picture frame frame 22, and are arranged at intervals in the horizontal width direction (arrow X direction) of the picture frame frame 22. Further, both end portions in the longitudinal direction of each rectifying plate 26 are respectively joined to the frame portion 24 (see FIG. 2) of the picture frame frame 22.

The plurality of rectifying plates 26 are arranged with the plate thickness direction as the width direction of the frame frame 22, and partition the inside of the frame frame 22. Thereby, a flow path 28 through which air-conditioning air flows is formed between adjacent rectifier plates 26 .

Note that a moisture-absorbing heat-generating material 40, which will be described later, is provided on the rectifying plate 26 on the inner peripheral portion of the frame frame 22. Further, each current plate 26 is rotatable around the longitudinal direction. Thereby, as will be described later in the modification shown in FIG. 3, the inclination angle θ of the current plate 26 with respect to the axial direction V of the frame frame 22 can be changed (adjusted).

(Moisture-absorbing heat-generating material)
The moisture absorbing heat generating materials 30 and 40 are formed including moisture absorbing heat generating fibers. Specifically, the hygroscopic heat generating materials 30 and 40 are formed into a cloth-like (sheet-like) shape using hygroscopic heat generating fibers. The moisture absorbing heat generating material 30 is provided in each frame portion 24 of the picture frame 22.

As shown in FIG. 2, the moisture absorbing heat generating material 30 is bent into an L-shaped cross section along the side wall portion 24A and the frame portion 24B of the frame portion 24, and adhesive is applied to the side wall portion 24A and the frame portion 24B. It is fixed with double-sided tape, etc.

As shown in FIG. 1, the hygroscopic heat generating material 40 is provided on the rectifying plate 26 on the inner circumference of the picture frame 22. As shown in FIG. In the following, for convenience of explanation, among the plurality of rectifier plates 26 arranged in the width direction (arrow X direction) of the picture frame frame 22, the rectifier plates 26 arranged on both sides (both ends) will be referred to as the rectifier plates 26A, and these rectifiers will be referred to as rectifier plates 26A. The current plate 26 disposed between the plates 26A may be distinguished as a current plate 26B. Furthermore, when the current plates 26A and 26B are not distinguished from each other, they are referred to as the current plate 26.

The rectifier plates 26A on both sides are arranged along the inner circumferential portions of the picture frame frame 22 on both sides in the width direction. A hygroscopic heat generating material 40 is provided on these rectifying plates 26A. The moisture absorbing heat generating material 40 is provided from one end side to the other end side in the longitudinal direction of the rectifying plate 26A.

On the other hand, both ends of the plurality of rectifying plates 26B in the longitudinal direction are arranged at the inner circumferential portions of the picture frame frame 22 on both sides in the vertical width direction. Moisture-absorbing and heat-generating materials 40 are provided at both ends of the rectifying plates 26B in the longitudinal direction, respectively.

As shown in FIGS. 1 and 2, the hygroscopic heat generating material 40 is fixed with an adhesive, double-sided tape, etc. in a stacked state on one side surface 26S1 of the side surfaces 26S1 and 26S2 on both sides of the current plate 26A. ing. Similarly, the hygroscopic heat generating material 40 is fixed to one side surface 26S1 of both ends of the rectifying plate 26B with an adhesive, double-sided tape, etc. in an overlapping state.

Here, the moisture-absorbing heat-generating fibers are, for example, chemical fibers having high moisture-absorbing and releasing properties, such as acrylate fibers, or natural fibers. Therefore, when dew condenses on each frame portion 24 of the frame portion 24B, the dew condensation is adsorbed onto the moisture-absorbing heat generating material 30. Similarly, when dew condenses on the rectifying plate 26 on the inner peripheral portion of the frame frame 22, the dew condensation is adsorbed onto the moisture absorbing heat generating material 40.

In addition, the moisture-absorbing heat-generating fiber has high adsorption heat-generating property. Therefore, when the moisture absorbing heat generating materials 30 and 40 adsorb dew condensation, the moisture absorbing heat generating materials 30 and 40 generate heat, and each frame portion 24 of the frame portion 24B and the rectifying plate 26 on the inner peripheral portion of the frame frame 22 are heated. Ru.

(effect)
Next, the operation of this embodiment will be explained.

As shown in FIG. 2, for example, in the summer, cold air generated by an air conditioner (not shown) is blown into the room 10 through the duct 16 and the air outlet 20, as shown by arrow C. At this time, the cold air flows along the flow path 28 formed between the plurality of adjacent baffle plates 26 and is blown out from the air control port 20 downward.

At this time, the warm air in the room 10 flows, and as shown by the arrow W, the warm air in the room 10 flows into the frame frame 22 and the inner peripheral portion of the frame frame 22. Here, the frame frame 22 and the current plate 26 are cooled by the cold air passing through the air control port 20. Therefore, when warm air from the room 10 is supplied to the frame frame 22 and the inner circumferential portion of the frame frame 22, dew condensation tends to occur on the frame frame 22 and the rectifying plate 26 located at the inner circumference of the frame frame 22.

As a countermeasure against this, in this embodiment, moisture absorbing heat generating materials 30 and 40 are provided on the frame frame 22 and the rectifying plate 26 located at the inner peripheral part of the frame frame 22. More specifically, hygroscopic heat generating materials 30 and 40 are provided at both longitudinal ends of the frame frame 22, the rectifying plate 26A, and the rectifying plate 26B. As a result, for example, when dew condenses on the frame frame 22, the condensation is absorbed by the hygroscopic heat generating fibers of the hygroscopic heat generating material 30. Therefore, dew condensation on the frame frame 22 is suppressed.

Similarly, when dew condenses on the rectifying plate 26, the condensation is absorbed by the moisture absorbing heat generating fibers of the moisture absorbing heat generating material 40. Therefore, dew condensation on the current plate 26 is suppressed.

Further, the hygroscopic heat generating fibers of the hygroscopic heat generating materials 30 and 40 generate heat when they absorb dew condensation. As a result, the frame frame 22 is heated by the moisture-absorbing heat generating material 30, making it difficult for the frame frame 22 to form dew condensation. Therefore, dew condensation on the frame frame 22 is further suppressed.

Similarly, since the current plate 26 is heated by the hygroscopic heat generating material 40, dew condensation on the current plate 26 becomes difficult to occur. Therefore, dew condensation on the current plate 26 is further suppressed.

The condensation absorbed by the moisture-absorbing heat-generating materials 30 and 40 is released from the moisture-absorbing heat-generating materials 30 and 40 by the cold air passing through the air outlet 20. Thereby, when dew condensation occurs on the frame frame 22 or the rectifying plate 26, the moisture absorbing heat generating materials 30, 40 can absorb the condensation again. As the moisture-absorbing heat-generating materials 30 and 40 repeatedly absorb and release moisture, dew condensation on the frame frame 22 and the rectifying plate 26 on the inner peripheral portion of the frame frame 22 is suppressed over a long period of time.

Furthermore, in this embodiment, the moisture-absorbing heat-generating materials 30 and 40 are provided on the frame frame 22, which is prone to condensation, and on the rectifying plate 26 located on the inner circumference of the frame frame 22. Thereby, dew condensation on the air termination port 20 can be efficiently suppressed.

Moreover, in this embodiment, the moisture absorbing heat generating material 40 is provided on one side surface 26S1 of the current plate 26. Here, as described above, the moisture absorbing heat generating material 40 generates heat when it absorbs moisture from the dew condensation on the rectifying plate 26. As a result, one side surface 26S1 of the current plate 26 is heated, so that dew condensation on the side surface 26S1 is suppressed. Further, the heat of the moisture absorbing heat generating material 40 is transmitted from one side surface 26S1 of the current plate 26 to the other side surface 26S2 of the current plate 26. Therefore, dew condensation is suppressed not only on one side surface 26S1 of the current plate 26 but also on the other side surface 26S2 of the current plate 26.

Therefore, in this embodiment, compared to the case where the moisture absorbing heat generating material 40 is provided on one side surface 26S1 and the other side surface 26S2 of the straightening plate 26, the moisture absorbing heat generating material 40 can suppress dew condensation on the straightening plate 26, and The material cost of heat generating fibers can be reduced.

(Modified example)
Next, a modification of the above embodiment will be described.

FIG. 3 shows an air terminal 20 according to a modified example. In this air control opening 20, a plurality of (three in this modification) rectifying plates 26 are arranged in the center of the frame frame 22 along the axial direction V of the frame frame 22. As a result, the cold air is blown out downward along the rectifying plate 26 at the center of the frame frame 22, as shown by arrow C.

On the other hand, a plurality of (eight in this modification) rectifier plates 26 on the inner peripheral side of the frame frame 22 are arranged on the outer side of the frame frame 22 from the duct 16 toward the frame frame 22 with respect to the axial direction V of the frame frame 22. It is inclined towards. As a result, on the inner peripheral side of the frame frame 22, as shown by arrow C, the cool air is blown out to the outside of the frame frame 22.

At this time, the warm air in the room 10 flows, and as shown by the arrow W, the warm air in the room 10 is supplied to the picture frame 22 and the inner peripheral part of the picture frame 22, and the warm air in the room 10 is supplied to the center part of the picture frame 22. Warm air is supplied. As a result, dew condensation is likely to occur on the picture frame frame 22 and the plurality of rectifying plates 26 located at the inner circumference and center of the picture frame frame 22.

As a countermeasure against this, in this modification, hygroscopic heat generating materials 30 and 40 are provided on the picture frame 22 and the rectifying plate 26 located at the inner circumference and center of the picture frame 22, respectively. Thereby, dew condensation on the air termination port 20 can be efficiently suppressed.

Next, in the above embodiment, the air termination port 20 is H-shaped or V-shaped. However, as in the modification shown in FIG. 4, the air terminal 50 may be of the VH type or the HV type. That is, in the air termination port 50, the plurality of rectifying plates 26 are arranged in a grid pattern when viewed from the axial direction of the frame frame 22. In this air outlet 50, moisture-absorbing heat-generating materials 30 and 40 are provided on the frame frame 22 and the rectifying plates 26 at the outer periphery and center of the frame frame 22, respectively.

Further, in the modified example shown in FIGS. 5 and 6, the air terminal 60 is of a breeze type (line type). The air termination port 60 has an elongated rectangular shape as a whole. In this air outlet 60, for example, the frame frame 22 and all of the plurality of rectifying plates 26 are provided with moisture absorbing heat generating materials 30, 40.

Next, in the embodiment described above, the hygroscopic heat generating material 30 is fixed to the frame portion 24 of the picture frame 22 with adhesive, double-sided tape, or the like. However, for example, as in the modification shown in FIG. 7(A), the moisture absorbing heat generating material 30 may be fixed to the frame portion 24 of the picture frame 22 via a magnet 32.

Similarly, the moisture absorbing heat generating material 40 may be fixed to one side surface 26S1 of the current plate 26 via a magnet 42, as in a modification shown in FIG. 7(B). This makes it easy to attach the moisture absorbing heat generating materials 30 and 40 to the frame frame 22 and the rectifying plate 26.

Note that the magnets 32 and 42 are fixed in advance to the moisture absorbing heat generating materials 30 and 40 with an adhesive or the like.

Next, in the embodiment described above, the moisture absorbing heat generating material 40 is provided on one side surface 26S1 of the current plate 26. However, the moisture absorbing heat generating material 40 may be provided on both sides of the one side surface 26S1 and the other side surface 26S2 of the current plate 26. In this case, dew condensation on the current plate 26 can be suppressed more reliably.

Further, for example, the moisture absorbing heat generating material 70 may be formed into a cylindrical shape, as in a modification shown in FIG. 8 . Specifically, the moisture absorbing heat generating material 70 is formed into a cylindrical shape with a rectangular cross section. A rectifying plate 26 is inserted inside this moisture absorbing heat generating material 70. By forming the hygroscopic heat generating material 70 in a cylindrical shape in this manner, the hygroscopic heat generating material 70 can be easily attached to the current plate 26.

Further, in the embodiment described above, the moisture absorbing heat generating materials 30 and 40 are provided on the frame frame 22 and the rectifying plate 26 of the air outlet 20, respectively. However, the moisture absorbing heat generating materials 30 and 40 can be provided on at least one of the frame frame 22 and the rectifying plate 26 of the air outlet 20.

Furthermore, in the embodiment described above, the moisture absorbing heat generating materials 30 and 40 are provided on the frame frame 22 and the rectifying plate 26, which are made of metal, resin, or the like. However, the frame frame and the current plate only need to have a hygroscopic heat-generating material, and the frame frame and the current plate themselves can also be formed of a hygroscopic heat-generating material. In this case, the hygroscopic heat generating material is formed by, for example, reinforcing hygroscopic heat generating fibers with resin or the like.

Further, in the embodiment described above, the air termination port 20 is used as an air conditioning outlet. However, the air termination port 20 may be, for example, an air conditioning inlet, or may be a ventilation outlet or intake port.

Further, in the embodiment described above, the air outlet 20 is provided in the ceiling 12. However, the air terminal may also be provided on a wall, floor, or the like.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and the embodiment and various modifications may be used in combination as appropriate, and the gist of the present invention may be It goes without saying that the invention can be implemented in various ways without departing from the scope.
