Description

[Detailed Description of the Invention] The present invention relates to a heat insulating window equipped with a waterproof device.

Conventionally, various types of windows with waterproof devices have been proposed.

For example, an airtight material is attached to the frame that makes up the window frame and the stile that makes up the window shoji, creating an airtight space between them, and the airtight space is opened to the outside air through holes formed in the frame and the stile. It is known that the inside of a closed space is made to have the same pressure as the outside air.

In addition, as a heat insulating material, the upper, lower and vertical frames that form the window frame have a structure in which the indoor side member and the outdoor side member made of metal are connected via a heat insulating material, and a window shoji is placed within this window frame. It has been known.

Therefore, it is conceivable to combine both of the above for an insulated window with a waterproof device, but since the space communicates with the outside air, the outside air can enter the space and come into contact with the outside part of the window sash. The stile becomes a cold bridge, resulting in poor insulation.

Particularly when the outside temperature is low, such as during winter, condensation water forms on the indoor side of the stile.

The present invention was developed in view of the above circumstances, and its purpose is to make the space formed between the window frame and the window shoji installed in the window frame equal to the outside air, thereby improving the waterproof effect. To provide a heat insulating window with a waterproof device which has excellent heat insulating properties and can prevent outside air in a space from coming into contact with the outside part of a stile room of a window shoji and forming a cold bridge or forming dew condensation.
