2. Description of the Related Art A window device as shown in FIGS. 3 to 5, for example, is described in a general catalog for buildings issued by the applicant company, and has been widely used in Japan. This window device is constructed by fitting and supporting glass panels 5, 5 inside a window frame 4 formed by combining an upper frame 1, a lower frame 2, and left and right vertical frames 3, 3 into a rectangular shape. ing. In the illustrated example, the inside of the window frame 4 is divided into two in the left-right direction by the upright 6. The upper end of the upright 6 is joined to the central portion of the lower surface of the upper frame 1, and the lower end is joined to the central portion of the upper surface of the lower frame 2. The constituent members 1 to 6 of these window devices are made of aluminum alloy extruded mold members except for the glass panels 5 and 5. Although not shown in the drawings, a window device having a sliding door type, a push-open type, or an elevating type window shovel installed inside a window frame has been widely known.

By the way, the indoor side surfaces (the lower surface in FIG. 4 and the right side surface in FIG. 5) of the respective members 1 to 5, 5 and 6 which compose the window device as described above are more outdoors than the indoor temperature, such as during winter. When the temperature is high and the temperature difference is large, water droplets adhere. That is, each of the above-mentioned members 1 to 1 cooled by outdoor cold air
When indoor warm air touches the indoor side of 3, 5 and 6,
The water vapor contained in the indoor air is condensed and adheres to the indoor side surfaces of these members 1-3, 5 and 6 as condensed water.
Then, this condensed water flows down by gravity, and the lower frame 2
Collect on the upper surface of. In this way, the amount of dew condensation water accumulated on the upper surface of the lower frame 2 sometimes becomes a considerable amount, and if it is left as it is, the curtain, the velvet, etc. will be soiled.

For this reason, conventionally, the upper surface of the lower frame 2 is provided on a part of a corner block for connecting both longitudinal end portions of the lower frame 2 and inner peripheral side surfaces of the lower end portions of the vertical frames 3 and 3. A drain outlet is provided to discharge the condensed water accumulated in the. Attached to the indoor side surface of each of the above members 1 to 5, 5 and 6,

However, in the case of the conventional structure as described above, there are the following points to be solved.

The drainage port is easily clogged with dust or the like, and when it is clogged, dew condensation water remains on the indoor side. That is, not only dew condensation water, but also dust and the like floating indoors are likely to collect on the indoor upper surface of the lower frame 2. Then, if this dust or the like flows into the drain port together with the dew condensation water, the drain port becomes clogged.

When wind blows from the outdoor side (the upper side of FIG. 4, the left side of FIG. 5) on the wall surface provided with the window device, the air on the outdoor side enters the indoor side through the drainage port, thereby improving the indoor heating and cooling effect. It will interfere.
