Detailed ways

The insulating glass of the present invention will be further described in detail in conjunction with the drawings and embodiments below.

Please refer to FIG. 1 , an insulating glass 100 according to an embodiment of the present invention includes electrochromic glass 12 , spacer elements 14 and low-emissivity coated glass 16 . Wherein, the electrochromic glass 12 has a first surface 122 and a second surface 124 opposite to each other, and an electrochromic film layer 126 is formed on the second surface 124 . The low-emissivity coated glass 16 has a third surface 162 and a fourth surface 164 opposite to each other, and a low-emissivity film layer 166 is formed on the third surface 162 . The spacer element 14 is located between the second surface 124 of the electrochromic glass 12 and the third surface 162 of the low-E coated glass 16 .

Specifically, in this embodiment, the spacer element 14 has a top wall 141 , a bottom wall 142 , a first side wall 143 and a second side wall 144 . The first side wall 143 is opposite to the second side wall 144 and connected between the top wall 141 and the bottom wall 142 . The top wall 141 is connected to the second surface 124 , and the bottom wall 142 is connected to the third surface 162 . The first side wall 143 is close to the inside of the insulating glass 100 , and the second side wall 144 is close to the edge of the insulating glass 100 . The first sidewall 143 and the second sidewall 144 are connected between the top wall 141 and the bottom wall 142 to form an accommodating cavity 145 . The accommodating cavity 145 is filled with a desiccant 146, and the first side wall 143 is formed with an opening 147. In this way, if moisture enters the insulating glass 100, it can be absorbed by the desiccant 146 filled in the accommodating cavity 145, thereby ensuring the insulation of the insulating glass. 100 dry inside.

In order to fix the electrochromic glass 12, the spacer 14 and the low-emissivity coated glass 16 to each other, the top wall 141 and the bottom wall 142 of the spacer 14 can be connected to the second surface 124 and the third surface 162 by glue 17 respectively .

In order to improve the sealing effect of the insulating glass 100, the spacer element 14 can be located at the peripheral position of the second surface 124 and the third surface 162, and between the outer surface of the second side wall 144 and the second surface 124 and the third surface 162 Fill it with sealant to further prevent moisture or flying dust from entering the hollow glass 100 .

In particular, in the electrochromic glass 12, along the direction from the second surface 124 to the third surface 162, the electrochromic film layer 126 may sequentially include a first transparent conductive layer 1261, an electrochromic layer 1262, an ion conducting layer 1263 , an ion storage layer 1264 and a second transparent conductive layer 1265 . Moreover, the electrochromic glass 12 further includes an internal terminal 1266 , a wire 1267 and an external terminal 1268 . The internal terminal 1266 is located on the second surface 124 and forms ohmic contact with the first transparent conductive layer 1261 and the second transparent conductive layer 1265 respectively, and the external terminal 1268 is located outside the second surface 124 and is electrically connected to the internal terminal 1266 through a wire 1267. connect. The external terminal 1268 is used for connecting with an external circuit to provide power for the electrochromic glass 12 . Wherein, the wire 1267 can be passed through the glue 17 and the sealant 18 to ensure that the periphery of the wire 1267 is also sealed. In addition, since the electrochromic film layer 126 is sealed inside the insulating glass 100 , the electrochromic film layer 126 in this embodiment can save the use of protective layers, but the present invention is not limited thereto.

When in use, by changing the voltage on the electrochromic glass 12, the color of the electrochromic glass 12 can be darkened, the transmittance can be reduced or the color can be lightened, and the transmittance can be increased, thereby realizing the regulation of light or heat. For example, when a forward voltage is applied between the first transparent conductive layer 1261 and the second transparent conductive layer 1265, ions (H ⁺ , Li ⁺ ) in the ion storage layer 1264 will leave the ion storage layer 1264 and pass through the ion conduction layer 1264. Layer 1263 reaches the electrochromic layer 1262, and undergoes redox reaction with the material in the electrochromic layer 1262, showing that the color becomes darker and the transmittance decreases; when the first transparent conductive layer 1261 and the second transparent conductive layer 1265 When a reverse voltage is applied, the ions (H ⁺ , Li ⁺ ) will leave the electrochromic layer 1262 again, pass through the ion conducting layer 1263 to reach the ion storage layer 1264 to be stored, and the color becomes lighter and the transmittance increases. In this way, when the indoor temperature is high or the indoor light needs to be weak, a forward voltage is applied between the first transparent conductive layer 1261 and the second transparent conductive layer 1265 of the electrochromic film layer 126, and the insulating glass 100 can shield All or part of the sunlight plays the role of heat resistance or creating a private space; when the indoor temperature is low or the indoor light needs to be strong, the first transparent conductive layer 1261 and the second transparent conductive layer 126 of the electrochromic film layer 126 When a reverse voltage is applied between the conductive layers 1265, the insulating glass 100 can allow sunlight to enter the room as much as possible, so as to increase the indoor temperature or increase indoor lighting; thereby realizing intelligent control of indoor temperature and light. This "active" way of changing the light and heat properties of glass can make human beings who are active indoors more comfortable, and better reflect comfort and humanity.

At the same time, since the insulating glass 100 also includes the low-emissivity coated glass 16 , it can further play a role in energy saving, and further makes the insulating glass 100 have excellent energy-saving performance.

In addition, the combination of the electrochromic glass 12 and the low-emissivity coated glass 16 in the insulating glass 100 can also be in other ways. one side.
