Description

The present invention relates to a building that enables the elimination of triads that can avoid coronavirus infection (in the present invention, the building is a concept including, for example, a room, a karaoke room, a private room, and the like).

In order to avoid the three-csence condition that can spread the coronavirus infection, the following is required.

That is, the three-dense state is closed, dense, and close, and elimination of the three-dense is effective in preventing a new type of coronavirus infection. Therefore, the government and local governments have repeatedly called for avoiding the Three Cs.

The reason is as follows. "A closed space with poor ventilation", "a crowded place where a large number of people gather", and "a close scene where people talk and speak up close", and if these three conditions are met, an outbreak of infected people is likely to occur. Is known from domestic and foreign surveys. For example, the reason is that outbreaks have been confirmed in places such as houseboats, live houses, and social gatherings.

Specifically, the purpose is to avoid the environment where it is easy to inhale the coronavirus contained in the droplets scattered during conversations in a three-dense state, and also to eliminate the coronavirus caused by infection from people who have no mild or subjective symptoms. It is desirable to completely eliminate the new coronavirus.

For example, as is well known, in Tokyo, there are many cases of suspected infection at night clubs and other restaurants that are open at night, and a certain governor said on March 30, 2020, these stores and karaoke stores. We requested that we refrain from using such services for the time being.

However, at present, it is considered that no clear idea and structure have been proposed for a building having a structure that enables the elimination of coronavirus and the elimination of three densities by exhausting the polluted air in the room to the outside.

Considering the current situation based on the above requests, it is considered that no concrete guidelines have been given and no structural proposals have been made.

As an invention for achieving indoor air ventilation, there is an invention described in Japanese Patent Application Laid-Open No. 2017-161166 (Patent Document 1). The configuration is to send the underfloor air directly above along the wall surface from the suction port on the floor surface and exhaust it to the outside from the air outlet of the ceiling, and to use the ventilation fan attached to the ceiling of the room to blow the indoor air. It is sent toward the wall surface and combined with the indoor air (contaminated air) flowing through this wall surface, and this contaminated air is also efficiently ventilated.

(A) Schematic diagram showing the air flow of the entire building of FIG. 1, and (b) Schematic diagram showing the air flow of the entire building of FIG. 1 according to another embodiment. In FIG. 3, (a) a schematic diagram showing the air flow in the attic due to the operation of a fan provided in the attic when there is no wind, and (b) a schematic diagram showing the air flow in the attic due to the natural wind flowing through the attic.

Hereinafter, each embodiment of the present invention will be described in order based on the drawings, but the description is not limited to this description and each drawing. Therefore, it is within the scope of the present invention that the concepts are similar or consistent based on the description and each drawing.

1 and 3 are examples, and the building 1 is a Japanese house. The building 1 includes, for example, a roof 2, a wall 3 and a ceiling 4 that support the roof 2, and a floor 5 that supports the wall 3. The space divided by the ceiling 4, the wall 3, and the floor 5 is the indoor 100, and the outside of the building 1 is the outdoor 101. In the figure, 102 shows the building of the building 1.

In FIGS. 1, 4 (a) and 4 (b), the roof 2 includes a roof space 200 (attic), and the walls 2a and 2a in the longitudinal direction (building direction) of the roof 2 (in the paired structure, Each of the walls 2a (the same applies hereinafter) is provided with a blower 10 (each including one thereof; the same applies hereinafter), and each has an exhaust port 11. Each exhaust port 11 is provided with a shutter 12. The roof 2 may have a pointed roof (not shown). The shutter 12 is opened while the blower 10 is in operation. For example, as shown in FIG. 4 (a). However, it is automatically released in strong winds. For example, as shown in FIG. 4 (b). By utilizing the opening of the exhaust port 11, the contaminated air A in the roof space 200 is exhausted to the outside from the exhaust port 11.

FIG. 2 shows a bird's-eye view of the air flow in the room 100, the corner air outlet 15, the corner suction port 16, and the outside air corner suction port 21 after the roof 2 of the building 1 is removed. A schematic diagram is shown. In the figure, cut A is a schematic view of a bird's-eye view in a state where the ceiling 4 is cut in addition to the roof 2 of the building 1, and further, cut B is a state in which the ceiling 4 and the floor 5 are cut in addition to the roof 2 of the building 1. A schematic diagram of a bird's-eye view of the underfloor space 600 is shown. It shows that the contaminated air A is attracted to the corner of the building 1 by the second air flow A2.

As shown in FIGS. 3 (a) and 3 (b), a corner air outlet 15 connected to the directly above flow path 20, which will be described later, is formed at each corner of the ceiling 4. As a result, the contaminated air A sent from the directly above flow path 20 is blown out to the roof space 200. Although not shown, it is also effective to provide a shutter at the corner air outlet 15 so that the corner can be freely opened and closed. For example, it is considered to be effective for human overdensity and the presence or absence of contaminated air, and also useful for energy saving.

As shown in FIG. 3A, each corner of the wall 3 is a flow path 20 directly above the floor 5 to send air sent from the corner suction port 16 opened in the corner of the floor 5 to the ceiling 4, which will be described later. To form. The formation of the upper flow path 20 is due to the action of the flow rate and the wind speed of the contaminated air A blown out from the corner air outlets 15 opened at the respective corners of the ceiling 4 into the roof space 200. The flow of the contaminated air A is referred to as a first air flow A1. Further, the first air flow A1 has a function of attracting the air that flows or stays in the room 100 (stagnation air), and promotes the ventilation of the room 100. The function of attracting the air that flows or stays in the room 100 (stagnation air) is referred to as a second air flow A2. Further, air tends to stagnate in the vicinity of the wall 3, and the stagnation of contaminated air A is attracted to the first air flow A1 and sent to the corner air outlet 15. Further, as shown in FIG. 3B, the corner suction port 16 may have a slit shape, and the amount of air introduced into the room 100 from the corner suction port 16 may be adjusted.

In FIGS. 3 (a) and 3 (b), a plurality of the above-mentioned corner corner air outlets 15 are formed at each corner of the ceiling 4, and the contaminated air A from the corner air outlet 15 is the roof 2. The exhaust port 11 opened in the wall 2a and the blower 10 work to exhaust the air to the outdoor 101 via the roof space 200. The respective air flows are shown in FIGS. 3 (a) and (b) and FIGS. 4 (a) and (b).

In FIGS. 3A and 3B, a plurality of corner suction ports 16 are formed at each corner of the floor 5, and the corner suction ports 16 are connected to the underfloor space 600 of the underfloor 6 and are connected to the underfloor space 600. It is a structure connected to a plurality of outside air corner suction ports 21 formed at the corners of the wall 6a under the floor 6. Therefore, the outside air reaches the underfloor space 600 from the outside air corner suction port 21, passes through the corner suction port 16, and becomes the flow of the first air flow A1. That is, fresh outside air is taken into the room 100 to promote ventilation and / or dilute it. A shutter may be attached to the outside air angle corner suction port 21 as well.

As described above, in the present invention, the flow of air (fresh outside air and contaminated air A) is as follows. That is, the outside air is the outdoor 101 → the outside air angle corner suction port 21 → the underfloor space 600 → the corner corner suction port 16 (floor 5) of the floor 5 → the direct upper flow path 20 (the first air flow A1, and in principle, the contaminated air A. ), And the indoor air flow caused by this first air flow A1 (contaminated air A, second air flow A2) → corner air outlet 15 of the ceiling 4 → roof space 200 of the roof 2 → exhaust port 11 → It becomes outdoor 101. The underfloor space 600 is useful for cooling and heating the air.

Each of the above-mentioned air flows shows the air flow in the room 100, and also the air flow in the roof 2 and the roof space 200, centering on the flow of the flow path 20 directly above the room 100. As a result, ventilation of the entire building 1 becomes possible smoothly and efficiently through the air flow of the entire building 1. This air flow is shown in FIGS. 3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b).

As described above, FIG. 4A shows a state showing the air flow between the roof 2 and the roof space 200 due to the operation of the blower 10 and the like. I assumed that there was no flow in the outside air. Further, FIG. 4B shows a state in which the air flow between the roof 2 and the roof space 200 by natural ventilation is shown, and is effective under strong winds.

Further, as shown in FIG. 3 (b), a blower 10a is attached to each flow path of the first air flow A1, and an auxiliary blower 10b is attached to the flow path of each second air flow A2. It is also possible to promote that flow. That is, it is preferable to promote forced ventilation of the first and second air streams A1 and A2. Reference numeral 10c in the figure is a blower attached to the roof 2 to promote the flow of the contaminated air A staying in the roof space 200. These blowers 10a to 10c are deployed as needed. It is desirable to deploy it to promote ventilation.

The devices such as the blowers 10a to 10c and the shutter 12 described above may be controlled by a control mechanism (not shown), which is effective for the effectiveness of the automatic ventilation of the building 1, energy saving, and avoidance of three crowds.

The above-mentioned corner corner is, for example, a corner corner in which two walls 3, 3 are linked at 90 ° in an example in which the building 1 has four sides (including four walls 3), and this corner corner and / or Ideally, the upper flow path 20 is formed in the vicinity thereof, and the corner suction port 16 and the corner outlet 15 are similarly formed in the corner corner and / or the vicinity portion thereof. Is ideal.

Although not shown, the number of locations where the outside air corner suction port 21, the corner corner suction port 16, or the corner corner air outlet 15 is increased is increased with the intention of promoting overall ventilation of the room 100 and speeding up avoidance of three crowds. That is also effective. For example, at the opening location, suction is performed at any of the wall 6a, the wall 3, and / or the inside of the wall 2a of the roof 2, the room 100 such as the floor 5, the ceiling 4, and / or the roof space 200. It is also effective to open a mouth or an outlet. That is, the purpose is to secure the expansion of the air ventilation volume and to promote the overall ventilation.

The above-mentioned corner corner air outlet 15, corner corner suction port 16, exhaust port 11, outside air corner corner suction port 21, suction port, etc. are limited to the shapes of the mouth and the hole, for example, as shown in FIG. 3 (b). For example, all forms such as slits, pores, through holes, meshes, elongated holes, etc., or all forms such as gaps can be adopted, and necessary places such as floor 5, ceiling 4, wall 3, etc. And / or, the optimum air passage can be used for underfloor 6 and the like. As a result, the landscape of each place is not spoiled, and the form of the building 1 can be matched. In other words, it can meet all the needs of landscape, structure and strength maintenance.

Each of the above-mentioned examples is a preferable example. Within the scope of the gist of each of the embodiments, a structure in which a part of the configuration is changed, or a structure in which the same features and effects can be achieved, and the like are within the scope of the present invention.
