2. Description of the Related Art Conventionally, as indoor heating of a house, heating by an air conditioner (hereinafter referred to as "air conditioner") provided on an inner wall of a room has been known. In the case of heating by this air conditioner, the blowing of warm air may give discomfort, and the temperature increases near the ceiling, often resulting in an unfavorable health environment such as head and foot cold.

[0003] For this reason, in recent years, heating by a floor heating device is becoming mainstream. In the case of this floor heating, there is no blowing of warm air unlike an air conditioner, and the temperature is higher near the floor, so that a favorable thermal environment of head and foot heat can be realized.

[0004]

However, in the above-mentioned floor heating, as shown in FIG. 7, when the window (1) is cooled by the outside air, cold air (2) is generated near the window (1). The phenomenon that this cold air (2) flows toward the floor (3)
(Cold Draft) cannot be prevented, which causes local convection, which tends to cause a temperature difference in the room and lowers comfort. Moreover, when the window (1) is cooled, dew condensation occurs on the window (1),
There was also a problem that the room dries.

Accordingly, the present invention solves the above-mentioned problems, suppresses the generation of cool air near the window in the room, prevents dew condensation in the window, and keeps the indoor thermal environment comfortable. The purpose is to provide a window heating device that can be used.

[0006]

In order to solve the above-mentioned problems, a window heating apparatus according to the present invention includes a heating element integrally incorporated in a window frame into which a shoji is fitted or around the window frame.
By heating the window frame with the heating element, the shoji is heated.

Specifically, a heating element is incorporated in the lower chord of the window frame. The heating element is disposed over substantially the entire length of the lower chord material in the longitudinal direction. Further, a part of a floor heater is used as a heating element.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIGS. 1 and 2, a window heating device according to an embodiment of the present invention
The heating element (12) is integrated into a window frame (11) into which the (10) is fitted.

A shoji (10) is provided around a glass plate (13) around a metal frame-like frame (1 such as aluminum).
4) is attached. These windows (10) (10) are, for example, fitted into the window frame (11) so that they can be pulled. Shoji
(10) is not limited to such a pulling type, and may be, for example, a double door type, a pulling down type, or a fitting type.

The window frame (11) is composed of a pair of vertical frame members (20) and (20) and an upper chord member (21) connecting the upper ends of the vertical frame members (20) and (20).
And a lower chord member (22) connecting the lower ends of the vertical frame members (20), (20) to form a rectangular frame. These vertical frame materials (20)
(20), the upper chord material (21) and the lower chord material (22) are extruded products made of metal such as aluminum. And
The lower chord member (22) of the window frame (11) has a hollow structure as shown in FIG. 1, and a heating element (12) is mounted inside the hollow chord member.

The heating element (12) is composed of, for example, a strip-shaped electric panel heater, and has a pair of concave grooves (23) formed at both ends along the longitudinal direction thereof in the lower chord material (22). (23), with the heating surface (24) facing up,
It is arranged over almost the entire length in the longitudinal direction of (22). The heating element (12) is not limited to the panel-shaped heater, and may be, for example, an electric cord-shaped heater (25) as shown in FIG. The invention is not limited to the electric type, and may be, for example, a gas hot water type.

In FIG. 2, reference numeral (30) denotes a switch for controlling the energization of the heating element (12), which is mounted on a wall surface (31) in the room. This switch (30) is not limited to a type that turns on and off the power supply to the heating element (12), and for example, a type that can adjust the amount of heat generation,
A type with a timer function, a type that controls energization according to the environment around the window (10) such as indoor and outdoor temperature and humidity,
It may be of a type linked to a floor heating switch. Further, the mounting location of the switch (30) is not limited to the wall surface (31), and may be mounted on a window frame (32) surrounding the window frame (11), for example. In FIGS. 1 and 3, (33) is a foundation, (34) is a pull, (35) is a joist, (36) is a window frame base, (37) is a base material,
(38) is a floor material.

In the above configuration, when power is supplied to the heating element (12), the heating element (12) generates heat and the lower chord material (22) is heated. As a result, the vertical frame material (20) (2
0), and further, the upper chord material (21) is gradually heated by heat conduction,
The entire window frame (11) warms up. Also, the frame (14) of the shoji (10) in contact with the window frame (11) is heated by heat conduction, and
The plate (13) in contact with (14) also warms, and the entire shoji (10) warms.

When the entire window (40) is warmed in this way, as shown in FIG. 4, the air in contact with the window (40) also becomes warm and becomes warm air (41). Thereby, the generation of cool air near the window (40) in the room is eliminated, the occurrence of local convection is prevented, and the temperature in the room can be kept uniform. Also,
Since the entire window (40) is warmed, the occurrence of dew condensation can be prevented.

FIGS. 5 and 6 show a window heating device according to another embodiment. In this window heating device, the heating element (50)
As a floor heater laid on the floor in the room (60) (60)
Some of ... are used. That is, one end along the lower chord (52) is extended to the lower chord (52), and the lower chord is
By inserting it into the lateral groove (53) formed in (52), the heating element
(50) is incorporated.

The floor heating heaters (60) are not limited to panel heaters, but may be, for example, electric cord heaters. In this case, a part of the cord heaters is a lower chord material. (52) The heating element may be incorporated in the lower chord material by being routed inside. Also, the floor heater (6
0) (60) are not limited to the electric type, and may be, for example, a gas hot water type. The other configuration is the same as the configuration of the window heating device shown in FIGS. 1 and 2 and has the same operation and effect.

The present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention. For example, the location where the heating element is incorporated is not limited to the lower chord material of the window frame. For example, it may be incorporated in the wall around the window frame or in the base of the window frame.

[0018]

As is apparent from the above description, the window heating device of the present invention incorporates a heating element for heating the window frame, so that the entire window is effectively heated by heat conduction.
Generation of cool air near the window can be suppressed. Thus, local convection can be prevented, and the temperature in the room can be kept uniform. In addition, since the entire window is warmed, the occurrence of dew condensation on the window can be suppressed, and it is possible to prevent the indoor from drying, especially in winter, which tends to dry. Therefore, the indoor thermal environment can be maintained comfortably.

Furthermore, by eliminating dew condensation and preventing drying, the generation of mold and the like can be suppressed, the surroundings of the windows can be kept hygienic, and the life span of indoor wood-based products can be extended.

In a cold region, it is possible to prevent ice from being attached to the glass surface of the window or the like so that the outside cannot be seen.
Ice can also be prevented from hindering opening and closing.

Furthermore, the heat generated from the heat generating element is quickly and almost uniformly distributed over the entire window by incorporating the heat generating element in the lower chord of the window frame or disposing the heat generating element over substantially the entire length of the lower chord in the longitudinal direction. It can be communicated, and the heating performance can be improved.

Further, by using a part of the floor heating heater as the heating element, a heating element dedicated to window heating can be omitted, and the structure can be simplified and the construction cost can be reduced.
