Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blind as a solar shading device.

[0002]

[Prior art]

 As is well known, a blind is a system in which a large number of slats are arranged in parallel at intervals and the solar radiation is shielded by the degree of overlap between the slats.

Such a blind is usually provided along the window, but in recent years, in order to improve the indoor environment around the window and to save energy, a method as shown in FIG. 5 has also been implemented.

In FIG. 5, reference numeral 1 is a blind, and 2 is a window glass of a window, but there is a space 3 between the window glass 2 and the window 1. In order to efficiently exhaust the cool air or hot air that collects in this space 3 or to return it to the air conditioner 4, for example, in the case where the blind 1 is a horizontal blind in which the slat 5 extends horizontally, the air conditioner 4 is installed below the blind 1. An exhaust port 9 which is an end of a duct 8 having a fan 7 is provided at a position of a ceiling 6 which is an upper part of the space 3.

In this way, the air blown out from the air conditioner 4 partially enters the space 3 from the lower side of the blind 1, rises, is sucked into the duct 8 from the exhaust port 9, and is discarded outdoors. Or, it is returned to the air conditioner 4 via the room. As a result, the cold air outside the window is cooled in the space 3 by the window glass 2 and the warm air is collected by the solar radiation through the window glass 2 and the warm air is prevented from deteriorating the indoor environment.

[0006]

[Problems to be solved by the device]

 However, even if the cool air or hot air accumulated between the window glass 2 and the blind 1 is efficiently exhausted by the system as shown in FIG. 5, in the conventional blind, there is a flow space between the adjacent slats. The indoor air was sucked into the window side between the slats through the ventilation space, so the efficiency did not increase.

An object of the present invention is to eliminate the disadvantages of the conventional example and provide a blind capable of efficiently treating the air between the blind and the window glass.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a translucent film which is continuous in the parallel direction of the slats so that the side edges of the slats are connected to each other, and one side of the blind is closed by the translucent film. Is the gist.

[0009]

[Action]

 According to the present invention, since one side of the blind is closed by the translucent film, the air between the window glass and the blind and the room air are partitioned by this translucent film, and the both are not mixed. As a result, it is possible to efficiently exhaust the air between the window glass and the blind without sucking indoor air from between the slats.

Further, since the light is transmitted through the light-transmitting film, the control of the solar radiation in the blind can be performed in the same manner as the conventional one, and when the blind is wound up, the light-transmitting property is provided between the slats. The presence of the translucent film does not interfere with the blind operation as the film is folded and fits.

[0011]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a view of the blind of the present invention, in which the same components as those of FIG.

The blind 1 of the present invention is basically the same as the conventional one, in which a large number of slats 5 are arranged in parallel at intervals and the solar radiation is shielded by the degree of overlap between the slats 5.

In the present invention, the translucent film 10 continuous in the parallel direction of the slats 5 is provided such that the front side edge or the rear side edge of each slat 5 is joined. By thus providing the translucent film 10 on the blind 1, the translucent film 10 can close one side (window side or indoor side) of the blind 1.

The translucent film 10 is a synthetic resin non-breathable film and has flexibility.

Further, the size of the transparent film 10 is preferably such that it covers the entire surface of the blind 1, and the degree of the transparent property is appropriately selected depending on its application such as transparent or translucent. . Further, a heat ray reflective film may be used as the translucent film 10.

Between the adjacent slats 5, the translucent film 10 is provided with folds 11 so that the slat 5 side can be folded.

The blind 1 is provided so as to leave a space 3 between it and the window glass 2. An air conditioner 4 is installed below the blind 1, and a fan 7 is installed at the position of the ceiling 6 above the space 3. An exhaust port 9 which is an end of the duct 8 is provided.

Next, the usage will be described. When the blind 1 is expanded, the distance between the slats 5 also increases as shown in FIG. 2, but since the translucent film 10 is bonded to the side edge of each slat 5, the translucent film 10 also has slats 5. It will be spread out in between.

Since the translucent film 10 allows solar radiation to pass through, the solar radiation can be adjusted by adjusting the overlapping angle of the slat 5 as in the conventional case. As shown in FIG. 3, even if the angle of the slats 5 is changed, it does not affect the spread of the transparent film 10.

Moreover, since one side of the blind 1 (for example, the indoor side) is closed by the translucent film 10, the air in the window glass 2 and the space 3 of the blind 1 mixes with the indoor air on the opposite side of the blind 1. There is no such thing.

In this way, the air blown out from the air conditioner 4 partially enters the space 3 from the lower side of the blind 1, rises without mixing with room air, and enters the duct 8 from the exhaust port 9. It is either sucked in and thrown outdoors or returned to the air conditioner 4 via the room.

When the blind 1 is rolled up, the transparent film 10 is folded and set between the slats 5 by the folds 11 as shown in FIG. 4, so that the presence of the transparent film 10 is a blind operation. It does not hurt.

In the above embodiment, the horizontal blind in which the slat 5 extends horizontally has been described, but a vertical blind in which the slat extends vertically can also be applied by providing the translucent film 10.

[0024]

[Effect of device]

 As described above, the blind of the present invention can efficiently process the air between the blind and the window glass.
