DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window structure of a blow-out room which plays an important role in a ventilation function in an environmentally friendly house.

[0002]

2. Description of the Related Art In a general house, there is a case where a stairwell is formed in which an upper part of an entrance hall or a living room is opened to an upper floor. Such a blow-out room is generally intended to improve the feeling of opening by increasing the upper space, or to improve the design of the building.

An opening having a relatively large area for lighting is formed above the blow-out room,
Generally, a fitting window which cannot be opened and closed is provided in this opening. For this reason, the blow-off room is configured as a bright and comfortable space by natural lighting from the opening.

[0004]

However, in the blow-by room having the fitting window which cannot be opened and closed at the uppermost portion as described above, although good lighting can be obtained, the room temperature rises due to stagnation of hot air above. However, there is a problem that the comfortability is deteriorated by the radiation of hot air.

[0005] In particular, in an environmentally-friendly house that seeks to improve by taking ventilation without using air conditioning, which has recently attracted attention,
In order to treat the ventilation room as a space for circulating the indoor air and ventilating it, how to remove the hot air that has accumulated above the ventilation room in the middle and summer months is a major issue related to the livability of the ventilation space. It is a problem.

An object of the present invention is to provide a window structure of a blow-off room which can measure the ventilation above the blow-out room and smoothly remove the hot air staying at this location.

[0007]

In order to solve the above-mentioned problems, a window structure of a blow-out room according to the present invention is a window structure provided at the uppermost part of a wall of a blow-out room extending over two or more floors,
A plurality of stages are provided vertically adjacent to each other, and each stage is configured such that each window is rotatable around a horizontal axis and can be stopped.

In the window structure of the blow-out room, a plurality of windows are provided vertically adjacent to each other at the uppermost portion of the blow-out room, and each window is rotatable about a horizontal axis and has a desired rotation. By being configured to be able to stop or fix at the position, it is possible to introduce external wind and measure ventilation above the blow-off room, and remove hot air that has accumulated due to this ventilation.

The present inventor conducted experiments and airflow analysis simulations in order to remove the hot air stagnating at the uppermost portion of the blow-out room and to improve the livability. As a result, when a window that can be opened over the entire surface, such as a sliding window, is provided at the opening provided at the top of the blow-out room, the direction of ventilation cannot be controlled, and it is difficult to eliminate hot air. That is, the knowledge that, when a window capable of holding an oblique attitude by rotating about the horizontal axis is provided in the opening, it is possible to control the direction of the ventilation and remove the hot air that has stayed in a good state. I got

For this reason, the windows need to be provided in a plurality of stages in the vertical direction, and each window needs to be rotatable about a horizontal axis. In this way, by providing a plurality of windows vertically rotatable around the horizontal axis, it is easy to individually open and close the plurality of windows to control the direction of the wind introduced into the room, and Can be dispersed to guide the airflow in a preferable state.

In particular, by providing a plurality of windows vertically, when each window is rotated or stopped at a desired angle and fixed or fixed, each window exhibits a function as a wing, and the rotation angle of the window is adjusted. Accordingly, the direction of the airflow can be guided above or horizontally above the blow-out room, thereby achieving good ventilation.

It is preferable that the window is formed so as to be horizontally long along the blow-off portion as a whole. In this case, a plurality of windows may be arranged in the horizontal direction to be horizontally long, or one window may be used to be horizontally long. By configuring the window in this way, it is possible to uniformly ventilate the upper part of the blow-by room to remove hot air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the window structure of the blow-out room will be described below with reference to the drawings. FIG. 1 is a cross-sectional view illustrating a window structure of a blow-out room. FIG. 2 is a south view and a north view of a house having a window structure of a stairwell. FIG.
FIG. 4 is a diagram illustrating a ventilation state above a blow-by room when a window is opened.

The window structure of the blow-out room according to the present invention is configured such that ventilation can be ensured at the uppermost portion of the blow-out room formed over two or more floors and hot air staying in this portion can be eliminated. This is particularly advantageous when applied to an environment-friendly house in which a blow-off portion in a blow-out room is configured as a return space for air penetrating from a lower floor to an upper floor.

Next, a window structure of a blow-out room according to this embodiment will be described with reference to FIGS. In the figure, a blow-out room A is configured from the first floor 1 to the second floor 2, and further, a roof 4 is formed diagonally from the upper part of the second floor 2 to the roof 3.

The roof 4 is formed to be inclined obliquely upward from the south side to the north side (from the right side to the left side in FIG. 1) of the blow-out room A, and a portion corresponding to the roof 3 is formed in a penthouse shape. The ceiling 5 extending from the room A to the roof 3 is formed obliquely along the slope of the roof 4, thereby forming a ventilation space 6 extending from the room A to the roof 3 via the ceiling 5.

The house C according to the present embodiment is configured as an environmentally friendly house, and is configured to make full use of sunlight and natural wind to enhance comfort. For this reason, the roof 4 is provided with a skylight 4a for lighting that cannot be opened and closed, and a roof material provided with a solar power generation element is used on the roof surface. With this configuration, it is possible to realize sufficient lighting for the blow-by room A and the second floor 2, and to secure the warm air by taking in solar heat in winter.

However, the inclination and the configuration of the roof 4 and the ceiling 5 are not limited to the above configuration, and the roof 4 and the ceiling 5 may have any configuration as long as they cover the upper part of the blow-out room A.

The height of the eaves 8 on the south wall 7 of the blow-out room A is set lower than the ceiling of the second floor 2, and the wall 7 corresponds to the floor height of the first floor 1. Terrace window 9a, high window 9
b and a plurality of windows at a position close to the eaves 8
A window structure B composed of 10 is configured.

In the window structure B, a plurality of windows 10 are vertically arranged adjacent to each other in three stages at positions corresponding to the uppermost portion of the blow-out room A on the wall 7, and the window structure B is formed in the horizontal direction. It is configured by arranging it with a length substantially corresponding to the size. Therefore, regardless of the size of the window 10 in the horizontal direction, the window structure B is configured to be horizontally long as a whole.

The window 10 comprises a frame 10a and a shoji 10b.
10b is configured to rotate around a horizontal shaft (not shown) provided at an upper portion, and to stop or fix at a desired rotation position. Means for rotating the shoji 10b is not particularly limited, and may be configured to be able to rotate using a rope or a small motor.

The shaft for rotating the shoji 10b does not need to be fixed. For example, by pushing the lower end of the shoji 10b to the outside, the upper end can rotate while descending along the frame 10a. Such a configuration may be used. As the window 10 configured in this way, there are windows such as a rotating window and a sliding window, and these can be selectively used.

Each of the windows 10 constituting the window structure B is independently rotated so as to be independently rotated with respect to another vertically adjacent window 10 or another horizontally adjacent window 10. The angle is configured to be adjusted. Since the shoji 10b is configured to be rotatable about a horizontal axis, the shoji 10b
Is inclined at a desired angle, it is possible to control the direction of the airflow guided from the outside to the indoor according to the inclination of the shoji 10b.

That is, when the window 10 is closed and the angle of the shoji 10b is set to 0 degree, and when the lower side of the shoji 10b is rotated at a small angle of about 30 degrees so that the lower side moves outdoors, the external airflow is reduced. Along the upper part of the blow-off room A, and circulates toward the ceiling 5. When the shoji screen 10b is rotated so as to be substantially horizontal, the external airflow is guided substantially horizontally along the shoji screen 10b and circulates toward the second floor 2.

The height and width of the window 10 are not set uniquely, but are not limited to the volume of the blow-out room A, the height of the wall 7 corresponding to the uppermost portion, and the height of the wall 7 of the blow-out room A. It is set appropriately according to the dimension in the direction and the like. For example, the height of the window 10 is preferably in the range of about 250 mm to 600 mm, and the width is preferably of a size corresponding to the module set in the building.

Therefore, one window 10 may be arranged corresponding to the lateral dimension of the blow-out room A, and a plurality of windows 10 having a small width are arranged adjacent to each other to correspond to the lateral size of the blow-off room A. It is also possible to arrange them.

That is, when configuring the window structure B, it is essential that the windows 10 be provided vertically and vertically adjacent to each other, but it is not essential how many windows 10 are arranged in the horizontal direction. It suffices if the whole is arranged horizontally long corresponding to the size of the blow-out room A.

On the north side of the roof 4 corresponding to the roof 3, a wall 11 is formed substantially parallel to the wall 7 of the blow-out room A, and a plurality of windows 12 are also arranged on the wall 11. . The window 12
Is configured to be continuous with one side of a ventilation space 6 formed along the ceiling 5 from above the blow room A to the roof 3,
It has a function of blowing out the airflow flowing through the ventilation space 6 to the outside.

For this reason, the configuration of the window 12 is not particularly limited. In this embodiment, a window 12 configured similarly to the window 10 of the wall 7 is used. The window 12 is preferably provided on the wall 11 formed to face the wall 7, but need not necessarily be provided at the position facing the wall 7, and may be formed on a wall orthogonal to the wall 7.

Therefore, a ventilation space 6 whose upper and lower ends are opened and closed to the outside by the windows 10 and 12 is formed above the blow-off room A. The position of the window 12 is preferably higher than the position of the window 11, as shown in the figure. However, the window 12 does not necessarily need to be above the window 11, and may be at least equal to or higher than the height of the window 11. If the heights of the windows 11 and 12 are substantially equal, it is possible to expect a considerable effect by partially removing the hot air above the blow-off room A, if not completely.

Next, the ventilation state of the house C having the window structure B of the blow-out room A configured as described above will be described with reference to the schematic diagram of FIG. 3 obtained by simulation. This figure 3
Is when a south wind with a wind speed of 4.2 m / s blows against house C,
The window 10 provided on the wall 7 on the windward side and the window 12 provided on the wall 11 are appropriately rotated so that the window 10 is guided indoors and discharged from the window 12. The arrow shown in the figure indicates the direction of the wind.

In the figure, the windows 10 provided on the south wall 7 are each rotated such that the shoji screens 10b are inclined at about 30 degrees, and the windows 12 provided on the north wall 11 on the rooftop 3 are also provided. It has turned at substantially the same angle.

Part of the wind blowing outside of the house C becomes a strong airflow 21 along the roof surface of the roof 4 and flows near the top of the roof 4 and on an extension of the roof 4. Wall 11
Is lower than the pressure on the upper surface of the roof 4, and a weak airflow 22 opposite to the airflow 21 is formed in a portion formed by the north wall 11 of the roof 4 and the upper part of the roof 3. .

Above the blow-off room A, an airflow 23 guided by the window 10 flows along the ceiling 5 toward the window 12 on the rooftop 3 side. That is, a part of the wind blowing outdoors collides with the shoji 10b of the window 10 and is guided toward the ceiling 5 above the blow-out room A according to the rotation angle of the shoji 10b. And it becomes the airflow 23 along the ceiling 5, and hardly flows in the two directions on the second floor.

The air flow 23 flows along the ceiling 5 in the direction of the north window 12 and is discharged from the window 12 to the outside. In this process, the hot air staying near the ceiling 12 can be removed to the outside.

It has been confirmed that the effects on the discharge of hot air and the habitability almost coincide with the simulation in the measurement of the experimental house. Therefore, it is possible to eliminate the hot air stagnating above the blow-out room A without requiring any special power and without adversely affecting the second floor by the hot air.

Further, since the roof 10 is configured so as to be horizontally long as a whole corresponding to the lateral dimension of the blow-out room A, the airflow 23 is uniformly distributed along the ceiling 5 above the blow-out room A. Can be formed, and high livability can be exhibited even in the summer.

[0038]

As described above in detail, in the window structure of the blow-out room according to the present invention, the uppermost part of the blow-out room can be rotated vertically and vertically adjacently in parallel and in plural stages around the horizontal axis. In addition, by arranging a window configured to be able to be stopped or fixed at a desired rotation position, external wind is introduced to measure the ventilation above the blow-out room, and to remove the hot air that has accumulated due to the ventilation. Can be done.

In particular, when the windows provided in the upper and lower stages are rotated to a desired angle and stopped or fixed, each window exhibits a function as a wing, and the direction of the air flow is changed according to the rotation angle of the windows. It can be guided above or horizontally above the blow-out room, and thereby good ventilation can be realized.
