Description

  The present invention relates to an air distribution mechanism in a building composed of double walls for circulating air in a building using convection, and in particular, forms an air circulation path for increasing air circulation efficiency. The present invention relates to an air distribution mechanism in a building provided with a hood-like member.

  Conventionally, air conditioners in buildings have been often used with air conditioners such as air conditioners in the summer, and in the winter there are underfloor heaters that use electric appliances, gas, etc., as well as air conditioners, stoves, and gas heaters. It is widespread and it is possible to construct a comfortable living space. In addition, a centralized air-conditioning management system that can automatically manage the temperature, humidity, etc. of all living rooms has become widespread, and a building equipped with a 24-hour ventilation system that continues to exhaust the air in the building There are many.

  In recent years, there has been a widespread attempt to use natural energy to obtain comfort in living spaces. For example, the temperature under the floor is kept low even in the summer, and the inside of the outer wall on the south side is heated by the solar heat even in the winter. It is cool and the living space is warmed by circulating the warm air heated by solar energy in winter. By the way, the energy that circulates and distributes the air in the building uses ascending airflow that is generated when the air is warmed by sunlight as power.

  In this way, from the viewpoint of preventing global warming, various technologies related to environment-friendly energy-saving air-conditioning equipment have been developed, and consumers with high environmental awareness demand such products and services. It has become a trend.

  The applicant of the present invention is a patent holder of Japanese Patent No. 3117933 (Japanese Patent Laid-Open No. 10-325585), and Japanese Patent No. 4314408 (Japanese Patent Laid-Open No. 2006-46669) and Japanese Patent No. 4947746 (Japanese Patent Laid-Open No. 2012-219476). Inventor and patentee. These are all inventions related to energy-saving buildings in which the wall of the building in consideration of the environment has a double structure.

  Japanese Patent Laid-Open No. 10-325585 (Patent No. 3117933) provides a space for circulating air through a double wall in a building, and the space is naturally warmed or cooled by heating sunlight. The air will circulate and start, but by accelerating, accelerating or shutting it down, it can be actively used for heating or cooling in the building, reducing the fuel consumed for heating and cooling, Techniques for reducing the load on natural resources are disclosed. Japanese Patent Application Laid-Open No. 2012-219476 (Patent No. 4947746) discloses a technique related to air conditioning that uses natural energy with higher heating / cooling effect that accelerates the air circulation speed and improves the sealing performance when the air circulation is stopped. Has been.

  Japanese Patent Application Laid-Open No. 2006-46669 (Patent No. 4314408) discloses a technique related to an underfloor ventilation device installed under the floor of a building having a specification for circulating air in the building. Since these all use natural energy to air-condition the building, it can be said that the building using these technologies is sufficiently environmentally friendly.

  In any of these inventions, the force of circulating air in the building is obtained by flowing the air in the air circulation layer composed of the double wall provided on the side wall and the roof portion of the building. Although the structure circulates warm air or cold air, the speed at which the warm air / cold air circulates depends on the speed of the updraft flowing through the air circulation layer.

  In other words, the speed of the updraft is the speed at which the building is heated and cooled, so when performing such air conditioning using only natural power without using power such as electricity, In order to accelerate, it is necessary to improve the efficiency of intake and exhaust, and a structure for performing such intake and exhaust is required. In each of the above-described inventions (particularly, Japanese Patent Application Laid-Open No. 2012-219476 (Patent No. 49947746)), the opening / closing efficiency of the lid that seals the exhaust port of the air circulation layer is increased so that the lid can be easily closed even with a moderate updraft. It was possible to open the body and circulate the air, thereby ensuring the speed of the updraft, but it was not sufficient because it was not a structure that actively increased the speed.

In recent years, consumers are highly aware of the environment and tend to demand buildings that are sufficiently environmentally friendly, while also demanding convenience and comfort. In other words, there is a need for a technology related to an air flow device that makes it possible to quickly heat and cool while utilizing natural power, and the development of an air flow mechanism in a building that solves the above problems is required. It was an urgent matter.

In addition, since the exhaust hood is installed at a position where air is introduced into the air exhaust port, reliable exhaust is possible. In addition, the shape of the exhaust hood was cut obliquely from both end faces of the air circulation layer toward the air exhaust port, and an air flow collection slope consisting of a substantially triangular cavity with the discharge portion at the top was formed. Efficiency increases and the speed of the updraft in the air circulation layer increases. Further, since the airflow discharge slope having a hemispherical shape is cut at a position covering the air exhaust port, the collected air is collected to improve air escape and increase the exhaust efficiency.

  The in-building air circulation mechanism 100 according to the present invention is an air circulation mechanism including an exhaust hood 200, and as shown in FIG. 1, an air circulation layer 110, an air inlet 120, an air outlet 130, and the like. The frame body 140 and the side plates 150a and 150b are used for generating power used for air circulation in the building by being attached to the outer wall portion and the roof portion of the building.

  As shown in FIGS. 6 to 9, the in-building air circulation mechanism 100 is a member provided on the outer wall portion 12 of the building 10 and / or the roof portion 14 of the ceiling, and forms these into a double wall. The layers formed between the layers are air circulation layers 110 and 112. In this embodiment, as shown in FIG. 1, a rectangular frame 140 is sandwiched and fixed by two side plates 150a and 150b as shown in FIG. Layer 110 is formed.

  Usually, the outer wall portion 12 is vertical, and the roof portion 14 is installed in the building 10 with an inclination angle. Therefore, the outer surface is heated by being irradiated with sunlight, and the temperature of the internal air rises. As a result, an updraft is generated. This is a driving force for air circulation in the building 10.

  That is, in the situation where sunlight is not irradiated, the air in the internal space of the air circulation layer 110 is balanced and does not move in the staying state, but sunlight is irradiated to the outer surface of the outer wall portion 12 or the roof portion 14. As a result, the air in the internal space is heated, an upward air flow is generated inside the air circulation layer 110, and an air flow is generated from the lower part of the air circulation layer 110 toward the upper part. The air circulation layer 110 is preferably configured to have a width that can accommodate air that generates an upward airflow when heated, but prevents the air that has been raised by heat from causing vortex retention or backflow. Therefore, it is desirable from the experience value that the width is within 24 mm.

  In addition, the air circulation mechanism 100 in the building is provided with an air inlet 120 at the bottom of the air circulation layer 110 and an air exhaust port 130 at the upper end. The air inlet 120 is composed of one or a plurality of perforations for taking outside air into the air circulation layer 110. In the case of a single perforation, a plurality of perforations are formed at the bottom of the air circulation layer 110 and at the center of the left and right. In this case, the air circulation layer 110 is provided at the bottom of the air circulation layer 110 and in a symmetrical position. The air exhaust port 130 is a single perforation that discharges air in the air circulation layer 110, and is formed at an upper portion of the air circulation layer 110 and at a central position on the left and right sides. The in-building air circulation mechanism 100 is installed on the outer wall portion 12 and / or the roof portion 14 of the building so that the air inlet 120 is on the bottom and the air exhaust port 130 is on the top.

  With this structure, the updraft generated in the air circulation layer 110 is discharged from the air exhaust port 130, and as a result, the air under the floor or in the building space enters the air circulation layer 110 via the air inlet 120. be introduced. At this time, when there are a plurality of air inlets 120, if the air discharge efficiency is high, it becomes possible to suck more air into the air circulation layer 110, and as a result, more air is vigorously built. It becomes possible to circulate and circulate in the interior 10.

  An exhaust hood 200 as shown in FIG. 1 is provided in the air circulation layer 110 of the in-building air circulation mechanism 100. The exhaust hood 200 is a member having the shape shown in FIGS. 2 and 3, and is installed in the vicinity of the air exhaust port 130 at the upper end of the air circulation layer 110 in order to improve the exhaust / circulation efficiency of the air in the air circulation layer 110. Is done.

  The exhaust hood 200 is a thick partition member as shown in FIGS. 2 and 3, and as shown in FIGS. 1 and 8, the air hood 200 has air in the air exhaust port 130 formed at the upper end of the air circulation layer 110. It is installed in the in-building air circulation mechanism 100 so as to introduce the exhaust gas that has risen in the circulation layer 110. Since the exhaust hood 200 is used to efficiently exhaust the air rising in the air distribution mechanism 100 in the building from the air exhaust port 130, the width of the air distribution layer 110 so as to collect all the rising air. And is provided so that there is no airflow leakage over the entire width of the layer.

  Specifically, as shown in FIGS. 2 to 5, the shape of the exhaust hood 200 is provided from the lower side of the air exhaust port 130 toward the air exhaust port 130, and an airflow collecting slope 210 is provided inside the exhaust hood 200. Is provided. The airflow collecting slope 210 includes a cut surface 212 having a notch groove that is a lead-out path for the ascending airflow and having a symmetrical shape. The discharge portion 222 is formed from both side ends 142a and 142b of the frame 140 of the in-building air circulation mechanism 100. Are formed so as to form a substantially triangular funnel-shaped space having a discharge portion 222 as an apex that overlaps with the air exhaust port 130 cut obliquely toward each other. It becomes possible to efficiently collect the air rising along the substantially triangular space toward the air exhaust port 130 so as to be collected by the funnel.

  As shown in FIGS. 2 and 3, the substantially triangular cutting surface 212 having the discharge portion 222 as a vertex has a shape cut into a curved surface. That is, the cutting surface 212 of the airflow collecting slope 210 is directed from the both side ends 142a and 142b of the frame 140 toward the discharge portion 222 that overlaps the air exhaust port 130 so as to form a rounded triangular space when viewed from the front. Thus, the structure is cut into a curved surface. By setting it as this structure, an air density increases as an updraft progresses to the upper part of the air distribution mechanism 100 in a building. As a result, the acceleration of the rising air increases as compared with the linear one, and the momentum of the air discharged from the air exhaust port 130 is increased.

  The exhaust hood 200 is further provided with an airflow discharge slope 220. As shown in FIGS. 2 to 5, the airflow discharge slope 220 is connected to the airflow collection slope 210 and is provided with a hemispherical discharge portion 222 provided at a position overlapping the air exhaust port 130. That is, the discharge part 222 which becomes the upper end part of the airflow collecting slope 210 is connected to the air exhaust port 130 to form an integral space, and the opening of the hemispherical discharge part 222 covers the air exhaust port 130. Has been placed. With this configuration, the ascending airflow collected along the airflow collection slope 210 reaches the airflow discharge slope 220 and is easily flown to the air exhaust port 130 by the hemispherical discharge portion 222, enabling efficient exhaust. It becomes. The opening side of the discharge part 222 of the airflow discharge slope 220 having a hemispherical shape is disposed so that the airflow discharge slope 220 covers the air exhaust port 130, and therefore, has the same diameter as the air exhaust port 130. desirable.

  In the present embodiment, the airflow collecting slope 210 is provided with an inclination angle 214 as shown in FIGS. 3 and 5. The inclination angle 214 is provided on the wall surface side of the air circulation layer 110 where the air exhaust port 130 is provided, that is, from the side plate 150a toward the side plate 150b where the air exhaust port 130 is provided. 4 and FIG. 5, the inclination angle 214 causes the area where the exhaust hood 200 and the side wall 150a are in contact (see FIG. 4) to be larger than the area where the exhaust hood 200 and the side wall 150b are in contact (see FIG. 5). Yes. That is, with this configuration, the air rising in the air circulation layer 110 easily flows in the central portion of the air circulation layer 110 and is easily led out to the air exhaust port 130.

  The exhaust hood 200 can be made of a heat insulating material. In the present embodiment, the exhaust hood 200 is made of a heat insulating material having the same thickness as the air circulation layer 110. Thereby, it became possible to comprise the air distribution mechanism 100 in a building which has a heat insulation effect. In addition, although a polystyrene foam is used as a heat insulation material in this embodiment, the present invention is not limited to this, and general foam heat insulation materials, fiber heat insulation materials, vacuum heat insulation materials, and the like can also be used. However, since it is used for the outer wall and roof of a building, it is desirable that it is lightweight.

  As shown in FIGS. 6, 8, and 9, the in-building air circulation mechanism 100 according to the present invention includes an air circulation layer 110 provided on the outer wall portion 12 of the building 10 and an air circulation layer 110 provided on the roof portion 14. It is possible to adopt a configuration in which the air circulation layer 112 is formed integrally. 6, 8, and 9, the air inlet 120 is provided at the bottom of the outer wall 12, and the air exhaust port 130 is provided at the upper end of the roof 14, and is provided at the bottom of the outer wall 12. The air that has flowed in from the air inlet 120 becomes a rising air current, rises to the roof portion 14, and is discharged into the building 10 from the air exhaust port 130 provided at the upper end of the roof portion 14.

  With this configuration, air flows from the outer wall portion 12 to the roof portion 14, so that the momentum of air discharged from the top of the roof portion 14 into the building 10 is the outer wall portion. Compared with the example divided by 12 and the roof part 14, it becomes stronger.

  More specifically, as shown in FIGS. 6, 8, and 9, when air flows into the air circulation layer 110 from the air inlet 120 and is warmed by sunlight, an updraft is generated. When the air flow rises while being warmed and reaches the upper end of the outer wall portion 12, it flows into the air circulation layer 110 of the roof portion 14 as it is. The raised air reaches the air exhaust port 130 provided at the upper end of the air circulation layer 110 of the roof portion 14, is collected by the exhaust hood 200, and is discharged from the air exhaust port 130 into the building 10. FIG. 6 shows the air flow in winter, and the air flow outside the building and inside the building is blocked to circulate warm air into the building. FIG. 9 shows the air circulation in the summer, and it is a structure in which warm air is exhausted from the exhaust device 20 provided in the roof portion while taking outside air from the lower part of the building and circulating it.

  On the other hand, FIG. 7 shows an in-building air circulation mechanism 100 that has been used in the past. According to the method of separately installing the inlet and outlet in the outer wall portion 12 and the roof portion 14, it is installed in the outer wall portion 12. When the air that has flowed into the air circulation layer 110 from the air inlet 120 at the bottom of the air circulation layer 110 of the built-in air circulation mechanism 100 reaches the upper end of the outer wall portion 12, the building 10 Next, air flows into the air circulation layer 110 again from the air inlet 120 at the bottom of the air circulation layer 110 of the in-building air circulation mechanism 100 installed in the roof portion 14, and the roof portion 14. After reaching the upper end, the air is exhausted into the building 10 from the air exhaust port 130.

  In the conventional method of individually installing the in-building air circulation mechanism 100 on the outer wall portion 12 and the roof portion 14 (see FIG. 7), the momentum of the rising airflow is once discharged into the building 10 at the upper portion of the outer wall portion 12. It will decrease at the time. Further, since the roof portion 14 is inclined, the speed of the rising air flow is slower than that of the outer wall portion 12. That is, as a whole, the force of the ascending airflow that is the power of air circulation in the building 10 is not fully exhibited, and it is difficult to quickly circulate cold air or warm air under the floor in the building 10. It was.

  In the embodiment of the present invention shown in FIGS. 6 and 8, the air circulation layer 112 integrated with the air circulation layer 110 provided on the outer wall portion 12 of the building 10 and the air circulation layer 110 provided on the roof portion 14 is communicated. By forming the air that rises in the air circulation layer 110, there is no obstacle on the way, and a constant amount of air is always supplied from the air inlet 120. When reaching the exhaust port 130, the momentum becomes stronger than in the conventional structure, and it is possible to sufficiently exert the force of the ascending air current that is the power of air circulation in the building 10. By adopting this configuration, it becomes possible to quickly circulate cold air or warm air under the floor in the building 10.
