Description

  The present invention relates to an outside air intake device that is installed in front of a window or a sweeping window of a building to guide the wind in the vicinity of the building, particularly the direction of the wind blowing parallel to the window surface, toward the window direction to efficiently take the wind into the room. .

  Ventilation fans and air conditioners are used to ventilate the room and lower the room temperature during the warm season. These fans consume electricity, and the air conditioner discharges warm air to the outside, thereby reducing global warming and saving energy. Is not preferred. In order to lower the room ventilation and room temperature, it is effective to take in outside air from the windows, and it is preferable because it saves energy and is friendly to the global environment. However, even if the window is opened, if the wind is blowing parallel to the window surface, the outside air does not enter the room much because the air flows in due to the difference in specific gravity due to the temperature difference near the window. Also, when only a breeze is blowing, the outside air does not enter sufficiently regardless of the wind direction.

  As a device that increases the amount of outside air flowing into the room by changing the wind direction of the wind blowing parallel to the window surface to the direction toward the window, the windshields protrude outside the room at the left and right edges of the window. The windshield is provided with a ventilation hole and a wind guide member for opening and closing the ventilation hole. When the wind comes from the right side of the window in parallel with the window surface, the right ventilation hole is opened and the left ventilation hole is opened. There has been proposed a wind intake device in which wind is taken into a room through a window when the windshield is closed (Patent Document 1). This device is fixed to the building and cannot be easily removed. Therefore, in the case of a strong wind, there is a risk of being destroyed by wind pressure. In particular, in recent years, a violent typhoon, which has never been experienced before, often hits Japan, and it has to be said that the device such as Patent Document 1 is extremely likely to be destroyed by a strong wind. When the wind direction changes frequently, it is assumed that the wind guide body frequently collides with the wind shield plate to generate noise and eventually break down.

  Further, a wind guiding structure of an opening installed in a building so as to cover an opening provided to take in wind into the building has been proposed (Patent Document 2). The structure is generally composed of two sets in which two legs are connected in a V-shape, a shaft connecting the respective leg connecting portions, and one air guide body having one end fixed to the shaft. . The air guide is rotatable between the left and right legs around the axis as a rotation axis. In this structure, the ends of the four legs are fixed slightly outside the four corners of the opening so that the two sets of V-shaped structures are located above and below the opening and the air guide is vertical. When the wind blows from the right side along the opening, the wind guide is located along the left leg, and the wind hits the wind guide and the wind direction changes to the opening direction. When the wind blows from the left side, the wind guide is positioned along the right leg, and the wind hits the wind guide and the wind direction changes to the opening direction. However, this structure is also fixed to the building, and there is a risk of destruction due to strong winds.If the wind direction changes frequently, the wind guide frequently collides with the legs, generating noise, and eventually It is presumed to be destroyed.

  Further, a window for taking in wind, which is installed outside the window so as to cover the window, has also been proposed (Patent Document 3). The window has openings on the left and right side surfaces, and is a movable plate that opens and closes the openings. Is provided. When the wind comes from the right side of the bay window in parallel with the window surface, the right opening is opened and the left opening is closed by the plate, so that the wind is taken into the window from the bay window. This bay window is also fixed to the building, and like the inventions described in Patent Literature 1 and Patent Literature 2, there is a risk of destruction due to strong wind. When the wind direction changes frequently, the plate body is frequently opened. It is estimated that the vehicle collides with and generates noise, and eventually it is destroyed.

  The problem to be solved by the present invention is to reduce the consumption of electricity and oil by efficiently using the outside air for ventilation and cooling of a room, thereby contributing to the suppression of global warming and resource saving. Specifically, even when the wind is blowing parallel to the window surface or when it is a breeze, by providing an outside air intake device that can sufficiently take in outside air into the room by guiding the wind direction toward the window is there. It is assumed that the outside air intake device can be easily removed and stored in a safe place when it is unnecessary or in the event of a typhoon. Further, the present invention provides the above-mentioned outside air intake device, which is provided with a mechanism that does not easily fall down even when the wind pressure is equal to or higher than a certain level.

The inventor of the present application has conducted intensive studies, and as a result, a device in which two planar air guides are connected at intervals so that the mutual angle is 60 degrees to 120 degrees is provided near the outside of the window, and the wind guides are provided. By arranging it upright, the connecting part is close to the window, and both ends are away from the window, the wind direction of the wind blowing parallel to the window surface is changed to the window direction by the wind guide, so that it enters the room from the window. I found out. In addition, it has been found that when the breeze blows toward the window, the wind moves along the left and right wind guides, gathers in a gap between the connecting portions of the two wind guides, and the wind having increased wind speed blows into the window from the gap.
However, in the case where the wind guide was fixed, the device was blown down when the wind pressure exceeded a certain level. Therefore, in order to solve this problem, the air guide is formed by forming a sheet-like membrane on a square frame, and one end of the sheet is firmly fixed to one vertical side of the frame, and the other end is opposed to the frame. A magnet or hook-and-loop fastener is used on the side to be fixed so that it can be easily detached when the wind pressure exceeds a certain level. By this, when the wind pressure becomes a certain level or more, one end of the sheet of the wind guide body is detached from the frame, the sheet freely flows into the wind, the wind pressure received by the entire device is reduced, and it is possible to prevent the device from falling over. Was.

  The outside air intake device according to the first invention includes two planar air guides, and the two air guides are connected at an interval such that a mutual angle is 60 to 120 degrees. It is characterized by the following.

  The outside air intake device according to the second invention is the outside air intake device according to the first invention, wherein the air guide comprises a film-like body and a frame for fixing the film-like body, and one end of the film-like body is The frame is firmly fixed to one side and the other end is detachably fixed to a side of the frame opposite to the side.

  The outside air intake device according to a third invention is the outside air intake device according to the second invention, wherein one end of the film-like body is firmly fixed to one side of the frame, and the other end is the outside of the frame. It is characterized in that it is detachably fixed to a side opposite to the side by using a sheet-like magnet, a magnet, or a hook-and-loop fastener.

  By arranging the outside air intake device according to the present invention outside a window or a sweep window of a building, even when the wind is blowing parallel to the window surface, the outside air is sufficiently introduced into the room by guiding the wind direction toward the window. Can be taken into account. In addition, even when a slight breeze is blowing from the front, but only a small amount of outside air enters the room, the use of this outside air intake device enhances the wind by collecting wind in the gap between the joints of the left and right wind guides, It can reach the deeper part of the room and take in sufficient outside air. Sending this outside air to the deep part is effective in lowering the room temperature. In addition, when the wind pressure exceeds a certain level, one end of the air guide separates from the frame and freely flows into the wind.As a result, the wind pressure received by the outside air intake unit decreases, so that it does not fall over with a slight wind, ensuring unmanned safety. Can be done. On the day when a strong wind is predicted, the detachable portion may be removed in advance. Furthermore, even when a very strong wind such as a typhoon blows, the outdoor air intake device can be easily carried, and if it is stored in a safe place, there will be no destruction of the device and no damage to the building. By using the outside air intake device according to the present invention, indoor ventilation and cooling can be performed only by natural energy such as wind without consuming artificial energy such as electricity. Of course, the indoor temperature is not cooled below the outside air temperature by the present invention, but even in the case of using an air conditioner in summer, the power consumption of the air conditioner can be reduced by using the air conditioner after lowering the room temperature in advance according to the present invention. . For example, even if you use the air conditioner immediately in the dining room that you use immediately after returning home, you can save energy by opening the windows in the bedrooms and other rooms that you want to use after a while, lowering the room temperature using the present invention, and then operating the air conditioner immediately before use, even if you use the dining room immediately after returning home. Become. Furthermore, power outages have been occurring for a long time in disaster-stricken areas due to recent severe typhoons and other disasters. Even in such a situation, the present invention can make hospitals, nursing homes, shelters, and the like more comfortable if there is no wind. In addition, the mechanism of the present invention, which works on the safe side with one end coming off when the wind pressure exceeds a certain level, can be diverted to the fall of a tent caused by a gust or the collapse caused by a soundproof sheet on a demolition scaffold. I want to repeat.
