Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a stile made of aluminum (hereinafter abbreviated as aluminum), such as a sliding shoji, or a stile and a backbone.
This invention relates to dew condensation prevention fittings that can prevent dew from forming on the indoor side surfaces of fittings.

[Conventional technology]

In general, in fittings such as sliding shojis, which have extruded aluminum sections on the stile or the stile and backbone, the glass surface of the fitting, the stile, and the backbone will change depending on the temperature difference between indoors and outdoors.

Condensation forms on the interior side of the fittings frame where the fittings are fitted,
This is especially noticeable in the winter.

Therefore, in conventional fittings, insulation material is interposed in the indoor/outdoor direction (thickness direction) of the stile, and plate glass is layered on the inside and outside of the stile or on the inner circumferential side surrounded by the stile and backbone. The idea is to prevent condensation by creating an insulating space between the inside and outside panels to insulate the outdoor and indoor sides.

[Problem to be solved by the invention]

However, as described above, it is difficult to reliably prevent dew condensation by insulating the outdoor and indoor sides of fittings. Therefore, it is conceivable to put a sheet of glass containing hot wires on the inner circumference of a frame, etc., and supply power to the hot wires from a general commercial power source to make the hot wires generate heat and prevent dew condensation. In addition to the complicated wiring that connects the
Since the fittings move, connection failures are likely to occur, and the challenge is to improve the power supply to the heated glass sheets.

The present invention solves the above-mentioned problems by using solar cells, allows relatively simple wiring for power supply to heat-wire board glasses, and reliably prevents dew condensation, which is useful for energy saving. The purpose is to provide preventive fittings.

(Means for Solving the Problem 1) The dew condensation prevention fittings according to the present invention include a plate-shaped solar cell facing outdoors on at least a part of the inner circumferential side surrounded by an aluminum stile or a stile and a backbone. , fix the battery at a suitable place in the fittings, connect the battery to the solar cell, and install a plate glass with hot wires or a plate glass with hot wires arranged on the surface attached to the frame or the area surrounded by the frame and the frame. A hot wire is connected to the battery via a switch.

[Function] The dew condensation prevention fittings of the present invention generate electricity from the solar cells by irradiating the solar cells with daytime sunlight, and send the electricity to the battery. During this time, the temperature difference between outdoors and indoors is relatively small.
Since dew condensation is less likely to form on the indoor side surfaces of the fittings and fitting frames, by leaving the switch OFF, the electricity generated by the solar cells can be stored in the battery. At night, when the temperature difference between outdoors and indoors is large, the switch is turned on and power is supplied from the battery to the hot wire, which generates heat and raises the temperature of the glass sheet containing the hot wire, causing the glass to pass through the frame and backbone. Heat is conducted to the frame through these, thereby warming the indoor side surfaces of the fittings and the frame as a whole, and reliably preventing dew condensation on these surfaces. In addition, in the present invention, it is only necessary to connect the solar cell and the battery, and the battery and the hot wire inside the fittings, and no external power source is used, so the wiring for supplying power to the hot wire is relatively simple. In addition to being easy to connect, it also reliably prevents condensation without causing poor connections.Secondly, since it uses solar cells, it also helps save energy.

On the inner periphery of the upper part surrounded by the frame (2) and the backbone (2a), the surface or both sides are protected with transparent plate glass (4a), and a light-transparent plate-shaped solar cell (4) is installed outdoors. A plate glass (5) containing a heating wire (5a) is integrally provided on the indoor side of the solar cell (4), and the plate glass (5) is also attached to the frame (2) and the backbone. It is stretched on the inner circumferential side of the upper part surrounded by (2a). Frame (2) and backbone (2a)

Oil mud The fittings of each example generate electricity from the solar cell (4) when daytime sunlight irradiates the solar cell (4) and sends the electric power to the battery (6). During this time, the difference in temperature between outdoors and indoors is relatively small and condensation is less likely to form on the shoji (1) and frame (3), so by turning off the switch (7), the battery (6) The battery (4) stores the generated electricity. During times when the temperature difference between outdoors and indoors is large, such as at night, turn on the switch (7) by operating the operation part (7a) from the indoor side, and disconnect the heat wire (
5a), the hot wire (5a) generates heat to raise the temperature of the glass plate (5) containing the hot wire (5a), and the hot wire (5a) is heated.
