Description

[Detailed description of the invention] This invention relates to a window equipped with an intake/exhaust device for utilizing solar heat.

As a return to the use of solar energy, a solar heat harvesting space is created between the double glass panels installed inside and outside the window or between the sliding glass doors, and an intake/exhaust space is created that allows communication with the indoor space above and below the space. By providing a vent, the cold indoor air is drawn into the solar heat collection space through the lower intake/exhaust vents, warmed, and the warmed air is discharged indoors through the upper intake/exhaust vents.
Various windows have been disclosed that promote indoor heat convection and utilize solar heat for heating.

However, as shown in Fig. 1, the conventional air intake/exhaust device is equipped with two glass plates installed inside and outside the window opening, or at the upper and lower ends of the inner side 1 of the sliding glass doors 1 and 2. 1 and an air intake/exhaust port 3.3 that can be opened and closed, and is further provided with a blind 5 having a heat absorbing surface and a reflecting surface in a solar heat collecting space 4 preferably provided between the inner and outer glass sliding doors 1 and 2. It was hot.

Incidentally, a window opening generally has an upper side at a position lower than the ceiling surface 6 and a lower side at a position higher than the floor surface 7.

In the conventional device, indoor air is directly taken in through the lower air intake/exhaust port 3 and discharged into the room directly through the upper air intake/exhaust port 3.

Therefore, conventionally, the very light warm air heated in the solar heat collection space 4 and released into the room from the upper air intake/exhaust port 3 rises to the indoor upper space shown by diagonal lines in FIG. 1 and accumulates there. In addition, the cold air, which has become heavier as the temperature drops, descends into the lower part of the room indicated by diagonal lines and accumulates there.

In other words, warm air and cold air accumulate outside the area of natural convection from the upper air intake/exhaust port 3 to the lower air intake/exhaust port 3 in the room.
The drawback was that solar heat was not utilized effectively.

This idea was made in view of the above points, and in addition to providing air flow paths extending above and below the solar heat harvesting space, intake and exhaust ports are provided at the upper and lower ends of each upper and lower air flow path. The purpose of the present invention is to provide a window that greatly improves solar heat utilization efficiency by opening into a room.

A solar heat collecting space Sp is formed between , d, and a normal type blind or a solar heat utilizing type blind B is provided in the space so as to be movable up and down.

A solar heat-utilizing blind is one in which the slats have been processed in some way to have solar heat absorption and reflection properties, and by changing the slope or spacing of the slats, solar heat can be absorbed or reflected. Yes, regular blinds refer to those that do not have such special processing.

Although there are no particular restrictions on the method of installing blind B,
In order to create a decorative effect inside the window, as shown in the example shown in the figure, blinds should be installed on the window frame of the outer sash, extending indoors from the inner glass shoji fitting part and surrounding the solar heat harvesting space. The frame Fb may be integrally formed, a plurality of known brackets 11 may be placed in front of the upper side 10 of the frame Fb, and the top rail 12 of the blind may be supported by the brackets.

When the blind mounting frame Fb is integrally connected to the outer sash window frame, a rectangular continuous heat insulating packing 13 is attached to the inner end of the blind mounting frame, and the heat insulating packing 13 is attached to the outside of the inner sash window frame Fi. If you put it close to the side,
Heat conduction between the inner and outer window frames is blocked, providing an insulating effect.

Of course, the blind mounting frame Fb is attached to the outside window frame Fo.
A heat insulating gasket, which is formed separately from the window frame and similarly attached to the outdoor end of the blind mounting frame, may be brought into contact with the indoor side surface of the outer sash window frame. Inconveniences caused by dripping of condensed water onto the slats 14 can be avoided.

Mu is an upper flow path forming member, and the cutout receiving part 26 at the upper end
and a closing plate portion 27 that hangs down from the cutout receiving portion.

The parting receiving part 26 is formed into a square Ω-shape for reinforcement, and the upper and lower two contact edges 26a and 26b are brought into contact with the indoor side surface of the wall Wu of the building, and fasteners such as nails 28. is fixed by
The upper surface supports the ceiling board 29.

The parting receiving part 26 also has the function of a spacer that separates the closing plate part 27 from the indoor side surface of 7Wu by a certain distance, and the closing plate part 27
The lower end portion of 7 is locked to the locking portions 2 and 3 of the upper frame H.

In this way, the upper flow path forming member forms a flow path Pu that connects from the solar heat harvesting space S to the vicinity of the ceiling surface via the vent hole 21 of the upper frame H between the closing plate part 27 and the indoor side surface of the wall. are doing.

Further, as shown in FIG. 2, in the upper part of the closing plate part 27, intake/exhaust ports 30 are provided at regular intervals in the horizontal direction to communicate the upper end part of the upper flow path Pu with the interior of the room. A large number of them are provided, and the lower surface of the cutout receiving part 26 and the closing plate part 2

6c and 27a, a sliding plate 31 having through holes (not shown) formed at equal intervals with the intake/exhaust ports 30 is slidably held via a knob 32, and this knob is moved from side to side. By moving it, the intake/exhaust ports 30 can be opened and closed.

Next, in the lower frame S of the inner satsushi window frame, the glass shoji d
An outer wall 36 and an inner wall 37 are provided at the outdoor end and the indoor end of the web 35 having rails 33, 34 which support the slides a and d4 in a sliding manner. 36 is provided with a vent 38 that communicates the lower end of the solar heat collecting space Sp with the inside of the lower frame.

Furthermore, a mounting wall 39 is provided at the lower end of the outer wall that extends indoors and then hangs down. stand 4
The fixtures 42 are fixed to the window sill by driving them into the window sill from their hanging parts.

Further, a locking portion 40 is formed at the lower end of the inner wall 37 and is bent inward in a stepped manner.

As in the case of the upper frame, the mounting wall 39 and the locking part 40 are separated from each other.

Ml is a lower flow path forming member.

This member is made in the same shape as the above-mentioned upper flow path forming member Mu, and is attached by arranging it vertically symmetrically.

However, from the lower frame S of the lower flow path forming member Ml, the cutout receiving portion 2
If it is necessary to make the distance to 6' smaller than the distance from the upper frame H of the upper flow path forming member Mu to the parting receiving part 26, the upper part of the closing plate part 27' may be appropriately shortened.

The parting receiving part 26' of the lower flow path forming member is formed by the waist wall We.
The upper end of the interior finishing material 43 is received, and the closing plate portion 27'
The upper end portion is locked to the locking portion 40 of the lower frame, and the closing plate portion is connected to the indoor side surface of the wall We from the solar heat collecting space Sp to the floor surface 44 through the ventilation hole 38 of the lower frame. A flow path P1 is formed that communicates with the air to a position as close as possible to the air.

A suction/exhaust port 30' that communicates the lower end of the flow path with the interior of the room is provided at the lower end of the closing plate, and this
A sliding plate 31' that opens and closes is attached.

It is also desirable that the lower intake/exhaust port 39' be opened at the same height as the floor surface 44; in that case,
The cutout receiving portion 26' receives the floorboard on its lower surface.

As described above, the upper flow path forming member Mu is connected to the upper frame H of the inner sash window frame to form the upper flow path Pu extending from the solar heat collection space Sp to the vicinity of the ceiling surface, and the upper flow path Pu is formed at the end of the flow path. In addition, a lower passage forming member Ml is connected to the lower frame S to form a lower passage extending from the solar heat collecting space Sp to a position as close as possible to the floor surface. P1 is formed, and a suction pipe communicating with the room is formed at the lower end of the flow path.
Since the exhaust port 30' is provided, the air warmed in the solar heat collection space Sp rises from the upper end of the space through the upper frame air vent 21 and the upper frame, rises inside the upper flow path Pu, and is discharged near the ceiling surface. It flows into the room from the intake/exhaust port 30.

In addition, the gradually cooled air falls near the floor surface, but the cold air near the floor surface is sucked into the lower flow path Pl from the intake/exhaust port 30' and passes through the inside of the lower frame S and the vent 38 to collect solar heat. It reaches inside the space Sp and is heated.

In this way, the indoor air circulates through the lower flow path P1, the solar heat collection space Sp, and the upper flow path Pu without stagnation of either warm air or cold air indoors, and solar heat is effectively utilized for heating.

Of course, the glass shoji d1 built into the outer sash
, d2, there is a suction valve that can be opened and closed above and below it.
If exhaust ports 45 and 46 are provided, the internal and external intake/exhaust ports 3
0, 30', 45, and 46 are all open for efficient ventilation, and in summer, the outside intake/exhaust ports 4
When only 5' and 46 are opened, warm air does not accumulate in the solar heat collecting space and outside air can be constantly circulated, thereby preventing an increase in the indoor cooling load.

In addition, by lowering the blind and selecting the orientation of the slats, the solar heat harvesting space can be divided into a high-temperature outside air flow path and a low-temperature insulating air layer with the blind as a boundary, allowing cooling. There is an advantage that the effect is improved.

As in the illustrated embodiment, ventilation holes 21.38 are provided in the upper frame H and lower frame S of the inner sash window frame, and the upper flow path forming member M
By attaching U and the lower flow path forming member Ml to form the upper flow path Pu and the lower flow path P1 between the wall of the building, it is possible to form the upper flow path Pu and the lower flow path P1 without making any troublesome features on the building frame. , it is possible to obtain a convection promoting effect with simple construction.

In addition, the inner satsushi window frame has regular glass shoji d3, d
4 can be built in, and the disadvantage of the conventional disadvantage of having an intake/exhaust port in the glass shoji, which results in the lighting area and visual field being narrowed, can be solved.

However, in order to communicate the solar heat harvesting space Sp with the upper flow path Pu and the lower flow path P1, it is not necessary to make the upper and lower frames H and S of the inner sash into a special structure as described above.
, upper and lower frames with a conventional structure, 4 frames and a lintel 24,
A plurality of separating members (
A ventilation gap substantially similar to the vent opening 21.38 may be formed by interposing a vent (not shown) and securing it to the lintel and window.

Furthermore, the upper and lower flow path forming members Mu and Ml are not limited to those that cooperate with building walls Wu and Wl to form a flow path as shown in the figure, but may also be flow path forming members that are independent of the walls. A structure that forms a flow path may also be used.

Which one to use can be selected depending on the type of wall (true wall, large wall).

Note that, in the illustrated embodiment, the upstream/downstream word forming members Mu and Ml have a cutout receiving part and a closing plate part integrally molded.
They may be formed separately and then combined, or
In some cases, the parting part and part of the blocking plate (up to the intake/exhaust port and the sliding plate guide piece) may be molded together, and the remaining part of the blocking plate may be molded independently or with the upper and lower frames H and S, respectively. It may be formed integrally and the closing plate portion may be cut down depending on the height and height of the ceiling surface and floor surface of the building.

As described above, when using a window equipped with the intake/exhaust device of this invention, the warm air heated in the solar heat collecting space is introduced into the upper flow path from the upper end of the space and released into the room near the ceiling surface. In addition, the heavy cold air that gradually cools down and is still low in temperature is sucked into the lower flow path near the floor surface and flows into the lower end of the solar heat collecting space.

Therefore, both in the solar heat harvesting space and indoors,
Since ideal heat convection occurs without stagnation of warm or cold air, solar heat can be used for indoor heating with extremely high efficiency.

When the indoor temperature is higher than the outdoor temperature, the outer satsushi
If the exhaust vents or glass shoji are opened, cold air will flow into the room near the floor from the lower passage, and warm indoor air will flow outdoors from the upper passage near the ceiling, allowing for efficient ventilation. can.
