Abstract

PROBLEM TO BE SOLVED: To recovery dissipated heat on opposite surfaces of a blind without diffusing it into a room side by providing air blowoff outlets at a lower position in a back surface and a front surface of the blind, providing an upper opening, and further opening an air suction inlet laterally toward the blind prodtruding it from a ceiling side in the vicinity of a front surface side. SOLUTION: An air blowoff outlet 20 is opened upward slightly larger than a lower region just below a blind 10 such that it covers the entire of the lower region on the side of a front surface 10a and on the side of a back surface 10b of the blind 10. In the air suction inlet 30 a duct 60 is protruded from an opening in a ceiling 50 surface on the inside of a room located slantingly frontally of the blind front surface 10a, and an end of the duct 60 is opened laterally toward the blind 10 side along the ceiling surface 50. An air stream from which dissipated heat is recovered rising along the back surface 10b strikes the ceiling 50 surface and is moved laterally on the ceiling 50 and is sucked in and recovered from the air suction inlet 30. An air stream rising along the front surface 10a showing a slight diffusion trend toward the inside of the room on an upper portion in the room is directly absorbed into the air suction inlet 30 as it is.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for recovering heat from a blind provided along a window surface of an air barrier air conditioner, and more particularly to a device for recovering heat load flowing into a room by recovering heat from the front as well as the back of the blind. This is a reduction.

[0002]

2. Description of the Related Art In a conventional air barrier air conditioner, air is blown out from an air outlet 200 provided below a blind 100 between a back surface of the blind 100 suspended at a predetermined interval from a window and a window. An air flow is blown upward by the fan 210 to collect heat radiated from the back of the blind 100 to the window side (FIG. 3). In addition, blind 10
The blown-out airflow from which the heat released from the back surface has been collected is collected by a suction fan 310 from an air suction port 300 having a lower opening opened on a ceiling surface almost directly above the blind 100.

[0003]

The heat dissipation of the blind is
Heat is dissipated not only from the back of the blinds to the window, but also from the front of the blinds to the indoor side. However, in the above-mentioned conventional method, only the heat radiation from the back of the blind to the window side is recovered, and the heat radiation from the front of the blind to the indoor side cannot be recovered. Also, the blown airflow rising between the window surface and the back surface of the blind spreads upward, and a part of the blown airflow hits the ceiling or the like, and may diffuse laterally along the ceiling surface. Further, there is a case where the light passes through the louvers of the blind, passes from the rear side of the blind to the front side, and diffuses to the indoor side. The air flow diffused in this manner is difficult to collect at the conventional air suction port having the lower opening. The present invention has been proposed in view of such a problem, and heat can be recovered from a blind by flowing an airflow to both sides of a back surface and a front surface of the blind, and without diffusing the airflow to the indoor side. It is intended to provide technology.

[0004]

According to a first aspect of the present invention, there is provided an air barrier air-conditioning window having an air outlet located below a blind provided on a window side of the air barrier and a position above the blind. A device for collecting heat dissipation of a blind by flowing an air flow along a blind surface to an air inlet of the blind, wherein an air outlet is provided with a blind rear facing a window side of the blind, and a blind front facing an indoor side. At the lower position on both sides of the blind, an upper opening was provided, and an air suction port was projected from the ceiling near the front side of the blind to open laterally toward the blind.

Further, in the invention according to claim 2, in the invention according to claim 1, the air outlet is formed in one upper opening corresponding to a lower range on both front and back sides of the blind. According to a third aspect of the present invention, in the first aspect of the invention, the air outlets are formed in a plurality of upper openings corresponding to lower ranges on each side of the front and back of the blind.

In the above construction, since the air outlet is provided at the upper opening at the lower position on both sides of the back and front of the blind, the air flow blown out from the air outlet is on both sides of the back and front of the blind. Rise along. Therefore, not only heat dissipation from the back of the blind to the window side, but also heat dissipation from the front of the blind to the indoor side can be performed. In addition, the airflow that passes between the louvers of the blind and passes from the back side to the front side is combined with the airflow that rises on the front side of the blind and is not easily diffused indoors. In particular, if the air outlet is formed in one upper opening corresponding to the lower range on both the front and back sides, the airflow blown upward from the air outlet will hit the lower end of the blind, etc. It is divided into a back side and a front side, and the air flow can be made to flow along both sides of the blind with a simple single opening configuration of the air outlet.

On the other hand, even if the air outlets are formed in a plurality of upper openings corresponding to the lower ranges on the front and rear sides, the air flow can be made to flow along both sides of the blind as described above. In particular, in such a configuration, since the air outlets are respectively provided at the front side and the rear side of the blind, the blown air flow does not directly hit the lower end of the blind, and there is no fear that the blind is shaken by the air flow. Further, in any of the above configurations, the air intake port is projected upward from the ceiling near the front side of the blind at a position higher than the blind and is opened laterally toward the blind, so that the rear side of the blind is closed. The airflow that hits the ceiling surface by ascending the side can be recovered by transmitting the airflow laterally through the ceiling surface.

Further, the air flow which rises up the front side of the blind and shows a slight tendency to diffuse upwards is also opened directly to the blind side, so that the air flow does not escape to the indoor side, so that it does not escape to the indoor side. Can be collected by suctioning to the side. In the present invention having the above-described configuration, while performing recovery by the airflow of heat radiation from the front of the blind to the indoor side, which was not possible with the conventional method, and efficiently recovering the airflow while preventing diffusion of the airflow to the indoor side, The heat load flowing into the room can be efficiently reduced.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a heat dissipation recovery device for a blind according to the present invention includes an air outlet 20 provided at a position below a blind 10 hung down along a window surface, and an air intake provided at a position above the blind 10. 30. The blind 10 of the present embodiment has a conventional configuration in which a plurality of louvers 11 each having a substantially rectangular shape are connected to each other so that the angle of the louvers 11 can be adjusted, and is hung down along a window surface. However, the blind 10 is not limited to such a configuration, and other types may be used.

As shown in FIG. 1, the air outlet 20 is provided to cover the entire lower area of the front side 10a and the rear side 10b of the blind 10.
Is formed in one upper opening of a substantially rectangular shape slightly larger than the area immediately below the upper part. The upper opening of the air outlet 20 is, as shown in FIG.
And the rear surface 10b are arranged such that the same opening area is allocated. Just above the central position of the air outlet 20 of the upper opening, the blind 10 is hung. Inside the air outlet 20, a blower fan 40 having a conventional configuration is provided so as to be able to blow airflow upward.

The air flow blown from the blower fan 40 is blown from the air outlet 20 toward the lower end of the blind 10 as shown in FIG. The outer edge portion of the blown air flow rises along the front surface 10a of the blind 10 and the back surface 10b of the blind 10 as it is.
On the other hand, the central portion of the air flow flux hits the lower surface of the lowermost louver 11 of the blind 10 and
The flow is diverted to the 0a side and the back surface 10b side (indicated by a dotted arrow pointing upward in the figure). The separated air flow rises on both sides of the blind 10 together with the air flow rising directly from the air outlet 20 on each surface. In addition, by setting the air outlet 20 having a single opening smaller than the above-described configuration and forming the opening corresponding to the width of the louver 11 of the blind 10, the entire blown air flow is controlled by the blind 1.
It may be set to 0 and divided. In such a case, it is more preferable that the lower surface of the louver 11 to which the blown air flow directly hits has a shape capable of splitting the flow, and is set to an appropriate weight so as not to be easily shaken by the air flow.

Further, as shown in FIG. 1, the air suction port 30 of this embodiment is provided with a ceiling 5 near the blind front 10a side.
It is provided on the 0 side. The duct 60 is projected from the opening on the ceiling 50 surface on the indoor side diagonally forward of the blind front 10a, and the end of the duct 60 is opened laterally toward the blind 10 along the ceiling 50 surface. Inside the ceiling 50 of the duct 60, a suction fan 70 of a conventional configuration is provided.
Is provided. The air flow that has recovered heat radiation (indicated by a double-headed arrow crossing the blind 10 in the figure) while rising along the back surface 10b of the blind 10 hits the ceiling 50 surface, further travels along the ceiling 50, and sucks air. It is sucked and collected from the mouth 30. On the other hand, the front 10a of the blind 10
Although the airflow rising along the line has a tendency to diffuse slightly upward in the room, it is directly sucked and collected in the air suction port 30.

In this way, the back 10 of the blind 10
Not only heat dissipation from b side to window side, but also blind front 1
The heat radiation from the 0a side to the indoor side is also collected by the air flow, and this air flow can be collected at the air suction port 30 without escaping to the indoor side. Further, in the above configuration, the air outlet 20 having the upper opening is provided.
2 is provided, however, as shown in FIG. 2, a plurality of air outlets may be separately provided for the blind front 10a and the blind back 10b.

FIG. 2A shows a front view 1 of a blind 10.
Air outlets 20a and 20b having upper openings corresponding to lower ranges of the respective surfaces on the 0a side and the back surface 10b side are separately provided with the same opening area. Furthermore, the air outlet 20
a and 20b are separated from each other by a blind 20c.
(The width of the louver is a guide). Therefore, the air flow blown out from the air outlets 20a and 20b is as shown in FIG.
As shown by the arrow in (a), since it does not hit the lower end side of the blind 10, the blind 10 is not shaken by the airflow,
Both sides of the blind 10 can be raised at the same flow rate. Further, in FIG. 2B, an air outlet 220 having an upper opening is newly provided beside the air outlet 200 having the conventional configuration so as to correspond to a lower area on the front side of the blind 100. The air outlet 220 is formed at an upper opening having the same area as the air outlet 200. Further, a diverter 410 is attached to the blower fan 400 so that air with a similar flow rate blows up from the air outlets 200 and 220.

In any of the above configurations, the air outlet 20
Alternatively, when forming 20a and 20b, blind 10
The opening areas of the air outlets corresponding to the respective surfaces of the blind 10 are set to be the same so that the air flows having the same flow rate flow on the front sides 10a and 10b of the blind 10. However, the front 10a side of the blind 10 and the back 1
The proportion of the opening area may be changed in accordance with the heat radiation amount on the 0b side so that an air flow having a flow rate corresponding thereto is obtained. For example, when the amount of heat radiation on the blind back 10b side is larger than that on the blind front 10a side, the opening area of the air outlet 20b provided in the lower range on the blind back 10b side may be larger than the air outlet 20a. Alternatively, the air outlet 20 having a single opening may be shifted so that the opening portion on the side of the blind rear surface 10b can be larger than the lower side of the front surface 10a.

Further, the air outlet 20 or 20a,
The opening area may be appropriately changed by, for example, configuring the 20b so as to cover the fixed opening surface with a sliding surface. Further, in the above-described configuration, the configuration in which one blower fan 40 is provided has been described. However, if necessary, separate fans may be provided for the front 10a side and the rear face 10b side of the blind 10, respectively. . Although only the configuration in which the air suction port 30 is provided on the ceiling 50 is shown, another air suction port provided in the lower opening on the ceiling 50 may be provided.

[0017]

According to the present invention, since the air flow can flow not only on the back side of the blind facing the window side but also on the front side of the blind, heat can be recovered from the front side of the blind to the indoor side. In addition, by providing the air inlet on the ceiling near the front of the blind and at the lateral opening toward the blind, the airflow on the front of the blind, which tends to diffuse into the room, can be sufficiently suctioned and collected. The diffusion of the airflow to the inside can also be suppressed. In this manner, the heat load flowing into the room can be reduced by the heat recovery by the air flow at the front of the blind and the efficient recovery of the air flow. Due to such a reduction in the heat load, the energy consumption for indoor cooling can be significantly reduced.
