JPH102156A - Bay window - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make it difficult to make natural ventilation when a door on the indoor side is not opened because there is only one surface of the wall surface faced to the atmosphere in a usual room and to stably make natural ventilation efficiently through only one window without using any electric ventilating fan for preventing odors, moisture, high temperature, etc., in a state to close the door on the indoor side. SOLUTION: An openable window is provided to the side of an overhanging section 2a of a bay window 2, as the basic form, it is divided into two up and down stages, a hinge of one (for example, the upper stage) of the windows or the same function is provided to the wall surface side of a building, a hinge of the other (for example, the lower stage) of the windows or the same function is provided to an overhanging section 2b, openings of four windows such as up and down and right and left are freely combined with each other, and optimum function of a guide wing can be displayed in accordance with the direction of the flow of the atmosphere.

Description

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 building having hydrodynamic characteristics.

[0002]

2. Description of the Related Art There are a conventional bay window 2 having an opening / closing portion on an overhanging surface 2a and an opening / closing portion on an overhanging side 2b. The hinges 4 for opening and closing are mounted on the same surface of either the wall surface 1b of the building or the bay window surface 2a. For this reason, when the wind flows along the window, the air current almost bypasses the room (see FIG. 5A), and when the wind blows at right angles to the window, the static pressure in the room increases, so that the outside air hardly enters the room. Since it does not flow, the air in the room is hardly discharged in any case. (See FIG. 5 (b))

[0003]

In order for the room to be effectively ventilated, the outside air intake (source) and the room air exhaust (sink) are located at the most upstream and the most downstream, respectively, along the flow. It is the best condition to be provided. In general, one room often has only one wall surface facing the outside air, so that the entrance on the indoor side must be kept open at all times in order to maintain good air permeability.

On the other hand, there are many places where it is difficult to always open the doors on the indoor side, such as bathrooms, toilets, storage rooms, etc., and they are left undesired due to the desire to improve air permeability due to odor, moisture, hot air and the like. That is the reality. To solve this, it is necessary to provide an electric ventilation fan, but providing it in each room is uneconomical in terms of equipment cost and power cost.

[0005] The present invention provides an economical method for efficiently taking in natural winds in a wide range of wind directions into a room without using electric power for the purpose of energy saving for the purpose of improving the environment and at the same time stably discharging the indoor air. To provide a reasonable window structure.

[0006]

In order to achieve the above object, according to the present invention, a window which can be opened and closed is provided on a side surface 2b of a projecting portion of a bay window 2, and the window is divided into two upper and lower stages (for example, one upper stage). The hinge 4 of the window 3 is provided on the wall surface side 1b of the building, and the hinge 6 of the other (for example, lower) window 5 is provided on the overhanging surface 2a.
The upper, lower, left and right windows can be freely combined with each other to provide the optimal function of the guide vanes according to the flow direction of the outside air. (Figs. 1 and 2)

[0007] The basic form is to provide four windows on the bay window overhanging part, upper, lower, left and right. As a simplified type, an upper opening is provided on one (for example, left) side surface and a lower opening is provided on the other (for example, right) side surface. Can be provided, but the effect is slightly reduced. (Fig. 3)

Further, by providing the fixed portion 7 between the windows 3 and 5 which can be opened and closed in two stages, the separation between the inflow side and the exhaust side can be further improved. (FIG. 4)

[0009]

1 and 2 show an example in which a hinge 4 of an upper window 3 is provided on a wall surface side 1b of a building, and a hinge 6 of a lower window 5 is provided on an overhanging surface 2a. When the wind blows at an inflow angle of about 0 to 45 degrees from the left as shown in FIG. 1 (a), both the left window 5 and the right window 3 are in the vicinity of the fully opened state.
In addition, when blowing near 45 to 90 degrees as shown in FIG. 1B, both the left window 3 and the right window 5 are almost half-open, so that the inlet is positive and the outlet is negative. Pressure works well. As a result, a stable large vortex is formed in the room,
On the other hand, since the heights of the inlet and the outlet are different, ventilation is effectively performed without causing a short circuit in the indoor airflow. That is, A
The flow from the point to E through B, C, D is stably obtained.

When the wind blows from the building (upper side in FIG. 1), it is difficult to expect sufficient ventilation. However, since a secondary flow is generated near the window due to the turbulence of the air flow, the secondary air flow is Ventilation is performed according to the wind speed.

When the wind blows from the right side of the figure, ventilation is performed as it is, but the same effect can be obtained by opening a window as in FIG.

[0012]

1 and 2 show typical examples. Two openable and closable windows 3 and 5 are arranged on the side wall 2b of the bay window overhang, and the hinge of the window 3 is attached to the wall surface 1b of the building, and the hinge of the window 5 is attached to the overhang surface 2a. And the other as the outlet.

In the embodiment shown in FIGS. 1 and 2, a simplified type is provided in which only the upper stage is provided on one (eg, left) side surface of the bay window overhang portion 2b and only the lower stage is provided on the other (eg, right) side surface. Thus, the scavenging effect is inferior to the basic type. (Fig. 3)

In the embodiment shown in FIGS. 1 and 2, the fixed portion 7 is placed between the upper and lower windows 3 and 5 of the bay window overhang 2, and is suitable when the room to be ventilated is high. (FIG. 4)

[0015]

According to the present invention, the following effects can be obtained by the above structure.

Due to the natural wind, the outside air can be efficiently taken into the room and the room air can be exhausted.

It is effective for a wide range of wind directions.

The outside air that has flowed into the room forms a large swirl that is stable inside the room, and replaces the room air with the outside air.
Completely discharged.

Since no electric power is required, it is suitable for energy saving.

[0020] Compared with a conventional bay window, the object is achieved with almost no increase in cost.

Since it is difficult to keep the door on the indoor side open, it can be mounted in a small room with poor air permeability, so that odor, moisture, high temperature, etc. can be easily prevented.

2. Description of the Related Art There are a conventional bay window 2 having an opening / closing portion on an overhanging surface 2a and an opening / closing portion on an overhanging side 2b. The opening / closing hinge or equivalent function 4 is mounted on the same side of either the left or right side of the wall 1b or the bay window 2a. For this reason, when the wind flows along the window, the air flow almost bypasses the room (see FIG. 5A),
When air is blown at right angles to the window, the outside air hardly flows into the room due to the high static pressure in the room, and in any case, the air in the room is hardly discharged. (See FIG. 5 (b))
