Description

  The present invention relates to a roll curtain device. In particular, it is related with the roll curtain apparatus provided with the solar cell.

Conventionally, many installation places where a solar cell is installed as a power source have been proposed to be part of a building. Installation on the roof of a building (for example, see Patent Document 1), installation on the roof of a building (for example, see Patent Document 2), and embedding a solar cell module in a precast concrete panel to the wall of the building What to use (for example, see Patent Document 3), installation of solar cells utilizing traffic buildings (for example, see Patent Document 4), installation of solar cell modules on the outside of a veranda or balcony wall or fence (for example, Patent Documents) 5).
Japanese Patent Laid-Open No. 06-085304 (Abstract, FIG. 1) Japanese Unexamined Patent Publication No. 07-180313 (abstract, FIG. 1) Japanese Patent Laid-Open No. 08-120825 (abstract, FIG. 1) Japanese Patent Laid-Open No. 2002-010494 (Abstract, FIG. 1) Japanese Patent Application Laid-Open No. 2002-134776 (Abstract, FIG. 1)

  There are few proposals for installation locations other than the above. The large surface that receives direct sunlight from the sun on the exterior of the building is a window. However, the installation of a solar cell makes it impossible for the window to function.

  The direct solar radiation entering the window on a sunny day is large, and a curtain is drawn to block this heat. In many cases, the curtains are lowered to block the glare of solar radiation even in winter. Curtains have been used to block solar radiation in order to help shield light and reduce air conditioning loads.

  Therefore, a problem to be solved is to secure a solar cell installation surface by utilizing a curtain of a building window.

  In order to solve the above-mentioned problems, the present invention provides a roll curtain for attaching a film type solar cell on a window side surface of a roll screen body, and connecting the film type solar cell as a power source to a storage battery and a load via a charge / discharge controller. A device. By sticking a film type solar cell on the window side surface of the main body of a roll screen by this, the arrangement | positioning surface of a solar cell can be effectively ensured in addition to the curtain function of a roll curtain, and it can also be made excellent in workability. Even in winter, roll screens are often lowered to block the glare of direct solar radiation, so sunlight can be used effectively. In addition, by installing a storage battery, it can be used as a backup power source when necessary and as an emergency power source in the event of a disaster.

  Further, if the storage battery is a film-type storage battery and is a roll curtain device that is attached to the interior side surface of the roll screen body, an apparatus in which power generation and storage are integrated can be realized. It can be an excellent device.

  If the load is a roll curtain device which is a roll screen winding or moving motor, the roll screen winding or moving can be realized by providing the roll curtain device with a motor.

  Further, if the load is a roll curtain device that is a light source that illuminates the roll screen, for example, a seasonal display that colors a night window can be shaped and expressed by the windows of the entire building.

  According to the present invention, a roll type solar cell is attached on the window side surface of the main body of the roll screen, and the roll type solar cell is used as a power source to connect to a storage battery and a load via a charge / discharge controller. In addition to the curtain function of the curtain, it is possible to effectively secure the arrangement surface of the solar cell and to have excellent workability. Even in winter, roll curtains are often lowered to block the glare of direct solar radiation, and sunlight can be used effectively. In addition, by installing a storage battery, it can be used as a backup power source when necessary and as an emergency power source in the event of a disaster.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an external perspective view of a roll curtain device according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the roll curtain device in FIG. As shown in FIGS. 1 and 2, a roll curtain device 1 is a curtain that stores a roll screen 3 and a main body 3a of the roll screen 3 wound around the roll core 3b while holding both ends of the roll core 3b. Box 2 is basically composed of. In this example, the curtain box 2 also stores a motor 4a that rotates the roll core 3b of the roll screen 3, such as an ultrasonic motor.

  In this example, the curtain box 2 includes a box frame 2a provided with upper left and right angles 2a1 and 2a1 for fixing the roll curtain device 1 to the ceiling material 20 of the building, and a front cover 2b attached to the box frame 2a. It consists of a rear cover 2c.

  The roll screen 3 has a roll screen main body 3a, a roll core 3b for attaching the upper end portion thereof, a lower end weight portion 3c attached to the lower end portion of the roll screen main body 3a, and a pull cord 3d attached to the lower end weight portion 3c by a pull cord attachment portion 3f. . A pull 3e is attached to the lower end of the pull cord 3d.

  Further, in the embodiment based on the present invention, the film type solar cell 6 is pasted on the window side surface of the main body 3a of the roll screen 3 and the film type storage battery 8 is rolled. The screen 3 is affixed to the interior side of the main body 3a. Thus, a roll curtain device in which power generation and power storage are integrated is realized, and the device is excellent in installation location and workability.

  In FIG. 3, the external view of an example of the sheet | seat of the film type solar cell 6 is shown. A sheet of a flexible film-type solar cell 6 in which a solar cell body 6a is formed on a plastic film 6b as a substrate, and is lighter than a rigid solar cell. A part of this sheet is adhered to the main body 3a of the roll screen 3 with an adhesive or the like.

  In this example, a charge / discharge controller 7 is installed in the curtain box 2 as shown in FIG. Further, a control circuit 5 for the motor 4a is also installed.

  In FIG. 4, the connection circuit of the film type solar cell 6 in the roll curtain apparatus 1 is shown with the block diagram. The film type solar cell 6 as a power source is connected to the storage battery, here, the film type storage battery 8 and the load 4 through the charge / discharge controller 7 as described above. The load 4 may be a motor or a lighting fixture.

  When the roll screen 3 is pulled down by this circuit for light shielding, the power generated by the film type solar cell 6 is adjusted by the charge / discharge controller 7 and stored in the film type storage battery 8. The motor 4a is driven by the stored electric power, and the roll screen 3 can be raised and lowered. For example, every time a switch provided in the pull cord attaching portion 3f pulls the pull 3e, the roll screen 3 can be switched between a winding direction, a winding direction, and a stop.

  Furthermore, in the case where a space is provided on the left and right of the roll screen 3, it is possible to have a structure in which the roll screen 3 can be slid to the left and right by a motor. For example, it can be realized by transmitting rotation of a motor using a shaft formed with a thread.

  Also, if the load is a light source that illuminates the roll screen 3, for example, a seasonal display that colors the night window by the stored electricity during the day is shaped and expressed by the window of the entire building, and the night city It is possible to add rich colors.

  As described above, according to the above-described embodiment, by attaching the film type solar cell on the window surface of the roll screen, the arrangement surface of the solar cell can be effectively secured in addition to the curtain function of the roll curtain, and the workability is improved. Can also be excellent. Even in winter, roll curtains are often lowered to block the glare of direct solar radiation, and sunlight can be used effectively. In addition, installation of a film-type storage battery can be used as a backup power source when necessary and as an emergency power source in the event of a disaster.

  As described above, the roll curtain device according to the present invention is useful as an emergency power source at the time of a disaster as it can effectively use solar energy as a power source, and has a great industrial applicability.
