Description

[Detailed description of the invention] The present invention relates to a solar heat utilization device, and more specifically, a blind type solar heat collector is installed in the space of a double-glazed window facing the outside air of a building, and The present invention relates to a novel solar heat utilization window in which the indoor side is movable relative to the outdoor side so that the space can be opened and closed from the indoor side.

The conventionally known structure consists of two glass plates facing each other with a space between them, a solar heat collector placed in the space, and air intake and exhaust ports that can be opened and closed above and below the space leading to the inside of the room. will be established.

In use, if both intake and exhaust ports are left open during winter sunshine, low-temperature indoor air flows into the space from the lower intake and exhaust ports, is heated by the solar heat collector, and heated air rises inside the space. enters the room through the upper air intake and exhaust vents and warms the low-temperature indoor air.

Also, at night, both intake and exhaust ports are closed to prevent air convection between the room and the space, and to prevent low-temperature air in the space cooled by outside air from flowing into the room.

However, in the conventional structure described above, the intake and exhaust ports are usually provided above and below the indoor window, which not only complicates the structure and increases construction costs, but also makes it difficult to ensure that the area of the intake and exhaust ports is sufficiently large. It was impossible.

In addition, due to the presence of intake and exhaust ports, the lighting area of the indoor window is reduced, and the use of set-in windows both indoors and outdoors reduces the need for inspection and maintenance of the heat collector and contamination within the space caused by indoor air flowing through. There were shortcomings such as no measures being taken to clean the area.

The present invention has been developed in view of the above, and is designed to solve all of the above-mentioned drawbacks by allowing the indoor side of a double-glazed window to move parallel and upward relative to the outdoor side.

The present invention will be described in detail with reference to Examples below.

In FIGS. 1 and 2, the window frame is composed of an upper frame 1, a lower frame 2, and left and right vertical frames 3.

A primary window 4 is vertically rotatably installed in the above window frame via upper and lower vertical shafts 5 and 6, and the outer peripheral edge of the primary window 4 is slidably connected to the inside of the window frame. Tight material 7, 7.
... is provided to seal the space between the primary window 4 and the window frame.

A transparent plate 8 is hermetically fitted on the outdoor side of the primary window 4 via a tight material 9 and a sealing material 10.

A secondary window 11, which will be described in detail later, is placed inside the primary window 4, that is, on the indoor side, and its four peripheral edges are brought into close contact with the four peripheral edges of the opposing primary window 4, so that a sealed space is formed between the windows 4 and 11. A space 12 is formed.

A blind solar heat collector 13 is disposed within the space 12.

The heat collector 13 is composed of, for example, a group of slats arranged vertically and in parallel at regular intervals, and the slat group includes a first slat 14 having a solar heat absorbing surface on its upper surface and a second slat 15 having a solar heat reflecting surface on its upper surface. and alternately.

As shown in FIG. 3, both slats 14 and 15 are provided with elongated holes 18 and 19 through which the slat hoisting cord 16 and slat lifting cord 17 are inserted, and tilting cords 20 are stretched at both ends of the slat 14 in the width direction. do.

Further, a stopper 21 is fixed to the lifting cord 17 at a position on the back side of the second slat 15.

In winter, when the lifting cord 17 is pulled up and the second slat is moved from the position shown in FIG. 4A to the position shown in FIG. Figure 4D).

Conversely, in summer, when the second slat 15 is pulled down and moved to the position shown in Fig. 4C, the upper surfaces of all the slats become only heat reflecting surfaces, reflecting solar heat rays to the outside (Fig. 4E).

Returning to FIGS. 1 and 2, the secondary window 11 is composed of an upper stile 22, a lower stile 23, and left and right vertical stile 24. 25 is fitted.

Note that 25 can also be made of a surface material such as frosted glass without using a transparent plate.

Almost secondary windows 1 are located on the upper edge of the upper stile 22 and the lower edge of the lower stile 23.
Tight members 26 each having a width dimension equal to 1 are attached.

In addition, vertically long tight materials 27 and 27 are attached to the indoor edges of the left and right vertical frames 4A (Fig. 2) of the primary window 4, and the secondary window 11
On the outdoor side of the window, an airtight plate 28.28 which faces and contacts the tight material 27.27 is formed integrally with or separately from the vertical stile 24.24 of the secondary window.

With the above configuration, the space between the primary window 4 and the secondary window 11 is substantially sealed.

In order to enable the secondary window 11 to move parallel and upward relative to the primary window 4, the present invention provides the following parallel movement and upward movement guide means.

29 is a shoji side board 30, a movable plate 31, and a small shoji side board 3
The substrate 30 and the substrate 32 are fixed to the primary window 4 and the secondary window 11, respectively, by means of an upper hinge member in which the substrates 2 are connected by pins 33A and 33B, respectively.

34 is a lower hinge member consisting of a shoji side board 35, a movable board 36 connected to the board with a pin 33C, and an L-shaped receiver plate 37. The board 35 is attached to the primary window 4, and the receiver plate 37 is attached to the 2 They are each fixed to the next window 11.

Note that the rotation radius 11 of the hinge member 29 is equal to the rotation radius of 1° of the hinge member 34, and the pin 33A vs. pin 33B and pin 33C.
The relative positions of the centers 36A of the rounded ends of the movable plates 36 are formed to be the same.

A sliding plate 38 is attached to the bottom surface of the secondary window 11, and a rotating lever member 39 is attached below the sliding plate 38 on the lower frame 2 of the window frame.

The rotating lever member 39 is connected to a rotating shaft 40 as shown in FIG. 1A.
It has a bundle 41 fixed to the rotating shaft 40 and a lever 42.

A ball 43 is rotatably attached to the free end of the lever.

When the bundle 41 is turned, the lever 42 stands up and the ball 43
The sliding plate and therefore the secondary window 11 are lifted up through the slide plate.

At the same time, the secondary window 11 connected to the primary window 4 by both hinge members 29 and 34 is displaced in the indoor/outdoor direction and vertically upward in a state parallel to the primary window 4, creating a gap between the windows. bring forth.

Since a rotatable ball 43 is provided at the end of the lever 42, the parallel movement of the secondary window 11 is performed smoothly.

When the lever 42 heated by the air in the space 12 is raised to form the above-mentioned gap during the winter sunshine, as described above, the low-temperature air in the room flows from the gap at the bottom to the space 12, as described in the prior art. The heated air that enters the room and is heated by the heat collector 13 returns to the room through the upper gap and contributes to heating.

At night, when the lever 42 is pushed down, the secondary window 11 is displaced vertically downward due to gravity and approaches the primary window 4, again forming a sealed space 12 between the windows.

In the summer, if the closed space 12 is closed and the reflective surface of the slat is turned up to reflect the sunlight toward the outside, the indoor cooling effect will not be impaired, and most of the outdoor temperature will not be conducted into the room. do not.

Incidentally, 44 is a screw attached to the secondary window, and 45 is a nut attached to the primary window, and the sealing between the primary window 4 and the secondary window 11 is completed by engaging them.

When inspecting or cleaning the heat collector 13, lift the lower part of the secondary window 11 toward the upper right in FIG. can lift the secondary window 11 at a large angle using the pins 33A and 33B as fulcrums.

Although the above-mentioned parallel movement/upward movement guide means uses hinge members at the top and bottom, the lower hinge member 34 may be omitted and a guide for guiding the ball 43 may be provided on the bottom surface of the sliding plate 38 instead.

Furthermore, if an appropriate spring (not shown) is interposed between the base plate 35 of the lower hinge member and the movable plate 36, the 2
The L-shaped size of the next window facilitates reassembly between the plate 37 and the movable plate 36.

In FIG. 1, reference numeral 46 denotes a blind mounting bracket for mounting the top box 47 of the heat collector to the secondary window 11.

A bundle 48, also shown in FIG. 2, is used to secure the primary window 4 to the window frame.

5 and 6 show another parallel movement/upward movement guide means of the present invention.

At least two pin brackets 5 having small diameter pins 49 facing inward are provided on the left and right vertical frames 4A, 4A of the primary window 4.
Fix 0 respectively.

Further, left and right guide plates 51,51 are attached to the outdoor side surfaces of the left and right vertical frames 24,24 of the secondary window 11, either integrally or separately.

Each of the guide plates 51, 51 is provided with at least two U-shaped engagement grooves 52, into which the pins 49 are fitted.

Recesses 52 are provided at the tops of both ends of the inclined sides of the U-shaped retaining groove 52.

When the pin 49 engages with the recess 52A, the secondary window 11 is in a parallel state, separated from the primary window 4, and elevated in the vertical direction; when the pin 49 engages with the recess 52B, the Close to window 4.

The vertical frames 4A and 4A of the primary window 4 are also provided with long tight members 53 that are in close contact with the side of the guide plate 51, so that even when the secondary window 11 is separated, the secondary window and the primary window are Seal the sides between windows.

Although the secondary window is operated manually in this embodiment, it may be moved using an operating fitting (not shown).

Also, the relationship between the pin and the guide plate can be reversed.

In both of the above embodiments, the heat collector 13 is attached to the secondary window 11, but it can also be attached to the primary window 4.

In addition, although the primary window 4 was explained regarding the rotating window structure, the primary window 4
It is also possible to make a window by fixing it to a window frame.

The present invention is structured as described above, and unlike conventional solar heating windows, the air intake and exhaust ports are not attached to the upper and lower parts of the secondary window, so the area of the transparent plate can be widened and it only contributes to indoor lighting. Naku 2
The structure of the next window is simplified, and the cross-sectional area of the intake and exhaust ports can be taken up to the full width of the window, so air circulation is complete.

Since the movement of returning the separated secondary windows to the close contact position uses gravity, the operation is extremely easy.

Furthermore, the present invention has many advantages such as being extremely economical because the mechanism for air circulation can also be used for inspecting the heat collector.
