Description

Smart blind window {Smart blind window}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smart blind window, and more particularly, to a window using a smart blind that is modularized to be interchangeable.

The electrochromic sheet such as a liquid crystal panel generally has a structure in which a polymer / liquid crystal composite material including a polymer phase and a liquid crystal phase is sandwiched between a pair of transparent plastic substrates having transparent electrodes made of indium tin oxide (ITO) . In general, the polymer / liquid crystal composite material is applied on a substrate, irradiated with ultraviolet rays, sandwiched again on the two substrates, and phase-separated to a milky white state. When the AC / DC composite material is applied to the substrate at a specific voltage, the polymer / liquid crystal composite material is induced. When the substrate is rotated and aligned, the light is transmitted and becomes transparent. If AC power is not applied, the light is not transmitted and becomes opaque.

Various kinds of liquid crystal panels have been proposed. FIG. 1 is a schematic view illustrating the structure of a liquid crystal panel. 1 shows a liquid crystal panel constructed by adhering a transparent electrode 12 and a transparent electrode 13 on both sides of a polymer / liquid crystal composite film 11 in which two kinds of polymer materials and a liquid crystal material are dispersed.

A transparent conductive layer 12a and a transparent conductive layer 13b are attached to the transparent film 12a and the transparent film 13a serving as a base respectively for the transparent electrode 12 and the transparent electrode 13 to form a polymer / Liquid crystal composite film 11 is in contact with the film 11 and a driving voltage is applied to the transparent electrode 12 and the transparent electrode 13 by the AC power source 15, the light transmittance of the polymer / ) Is not applied, the light transmittance decreases.

Since the electrochromic sheet 10 such as the liquid crystal panel can determine the transmission of light, it can form a smart glass or an intelligent smart by attaching it to a transparent window or a transparent door using a bonding film.

2 shows a plan view and a cross-section of a window with an electrochromic sheet attached thereto, in which a glass 20 is mounted on a window frame 30 such as a door or a window and an electrochromic sheet 10 To form a smart glass.

When a voltage is applied to the electrode lead line provided on the electrochromic sheet 10, the entire smart glass is in a transparent state, and if a voltage is not applied to the electrode lead line, the smart glass is entirely opaque and functions as a blind. Smart blind or electronic blind.

When the electrochromic sheet is attached to the window or door glass as shown in FIG. 2, the electrochromic sheet is exposed to the outside, and the impacted area may not be able to block or transmit light. However, there is a problem in that it is not possible to replace only the parts that do not function, and the entire electrochromic sheet needs to be replaced.

In addition, in order for the electrochromic sheet to adhere to the door or window glass, it is necessary that the transmission and blocking of the light should be uniform throughout and the transmittance must be high in order to act as a smart blind. The electrochromic sheet satisfying such conditions is extremely expensive. It is not difficult to keep the characteristics of the electrochromic sheet uniform and good in a narrow area, and it is possible to manufacture the electrochromic sheet at a low cost. However, if a window or a door is wide, a wide-area electrochromic sheet is required, and as the area becomes wider, the price of the electrochromic sheet per unit area is much higher. That is, maintaining uniform characteristics of the electrochromic sheet over a large area requires considerable skill and is reflected in the price.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a smart blind window having a structure in which an electrochromic sheet is not exposed to an external impact.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a smart blind window according to the present invention will be described in detail with reference to the accompanying drawings.

Disclosed is an electrochromic sheet comprising two sheets of window glass so as to prevent a sheet from being damaged by being exposed to the outside when the electrochromic sheet in a film form is used as a blind in a window, And a plurality of sheets are separated and modularized.

In addition, the present invention can modularize the electrochromic sheet in a state where it is attached to a transparent support plate such as glass or plastic, so that the inserted sheet module can be easily replaced. Further, in order to replace the seat module, a frame for fixing the seat module to the window frame may be provided on the frame so that the remaining seat module remains in place even when the seat module is removed.

FIG. 3 illustrates a plurality of blind modules modularized according to an embodiment of the present invention attached between two glasses constituting a window.

3, two glass pieces 131 and 132 constituting a transparent portion of a window are seated on the window frame 150 at predetermined intervals, and a plurality of modular blind modules 110 are mounted on the window frame 150, May be attached between the two glasses 131 and 132 so as to occupy all or at least a part of the unoccupied empty space (light-transmitting area).

The area of the film-shaped electrochromic sheet in the plurality of blind modules 110 is smaller than the cross-section of the glasses 131 and 132 constituting the window because the sheet for adjusting the light transmittance by the external power source is made of glass 131, 132), there is room for damage.

In FIG. 3, a plurality of blind modules having a long shape in the transverse direction are shown as being arranged in the longitudinal direction. Since most of the windows are opened and closed in the lateral direction, the direction in which the blind module is easy to replace is taken into consideration. However, the present invention is not limited to this, and a plurality of vertically long blind modules may be arranged in the horizontal direction, or may be arranged in the diagonal direction if necessary. Making the blind modules the same size can be advantageous when considering replacement.

The sheet support plate 115 may be made of glass or plastic having high transparency and may be formed to have a wider area than the sheet 111 to protect the sheet 111 without exposing the sheet 111, A predetermined distance d may be formed between the edge and the edge of the seat support plate 115. [ If the distance d is large, the sheet 111 can be surely protected. However, since the gap between the sheets 111 is widened in relation to the neighboring blind module 110, light may leak between the sheets 111, , And the interval d can be formed to be as small as, for example, about 2 mm.

As shown in Fig. 1, since the electrode is formed on the upper surface and the lower surface of the electrochromic sheet 111, the two electrode lead lines 112 and 113 are also formed on both the upper and lower sides of the sheet 111 .

FIG. 6 is a view illustrating a state where a plurality of blind modules are fixed to a window frame according to an embodiment of the present invention, Lt; / RTI >

5, support plate projections 115a and 115b are formed on both sides of the seat support plate 115 for supporting the electrochromic sheet 111. The seat 111 is formed on the projections 115a and 115b And projects further outward than the glasses 131 and 132 constituting the window. Further, the width of the support plate projecting portions 115a, 115b is formed to be narrower than the body width of the seat support plate 115. [

The blind module 110 is configured such that the support plate projections 115a and 115b are supported by the module support 151 formed outside the area where the glasses 131 and 132 constituting the window are seated, The position of the blind module 110 is fixed and the interval between the adjacent blind modules 110 is kept constant.

Since the module support 151 must be formed in the window frame 150 for supporting the blind module 110 inserted between the two glass pieces 131 and 132 and for seating the glass pieces 131 and 132, The glass 131, 132 can be formed only in a region where the glass 131, 132 is seated.

The module support 151 supports the support plate protrusions 115a and 115b formed to be narrower than the body width of the seat support plate 115 so that the blind module 110 is held in contact with the neighboring blind module 110 Can be mounted between the glasses 131 and 132 of the cabinet. The width or diameter of the module support 151 is formed to be narrower than the distance between the support plate projection of the first blind module and the support plate projection of the second blind module abutting the first blind module.

A power supply connection line 171 for supplying power to the blind module 110 may be formed on the frame 150 and connected to the electrode lead wires 112 and 113 provided on the blind module 110, It can be mounted more than the area where the glasses 131 and 132 constituting the window are seated so as not to interfere with the role of the transparent window.

The power supply connection line 171 may be composed of two lines and directly connected to the electrode lead lines 112 and 113 or the power supply connection line 171 may be composed of two power supply lines and one control line, 173 to the electrode lead lines 112 and 113 so that the operation of each blind module 110 may be separately controlled according to the control signal provided through the control line.

The frame 150 is provided with a power controller 175 to supply a power source for driving the color-changing sheet 111 to the power source connection line 171 or to supply power and control signals together.

7 shows a modified embodiment of the blind module according to the present invention in which the blind module 110 'is provided between two transparent sheet support plates 115, unlike FIG. 3 or 6, (111) may be supported and mounted between the two glasses (131, 132) constituting the transparent part of the window.

On the other hand, the module support 151, the power supply connection line 171, the switch 173, the power supply control unit 175, the support plate protrusions 115a, and 115b, which are disposed further outward than the areas where the glasses 131 and 132 constituting the window are seated, 115b and the like are not exposed to the outside, a frame cover (not shown) may be formed on the frame.

In order to replace the blind module 110 that fails to function properly, first the frame cover is removed and the failed blind module 110 and the power connection line 171 are disconnected to remove the failed blind module 110, The blind module 110 is inserted between the two sheets of glass 131 and 132 and supported on the module support 151 and the electrode lead wires 112 and 113 are connected to the power connection line 171 directly or through the switch 173, After connecting to the connection line 171, the frame cover can be mounted on the frame 150 again.
