Description

[Technical field]

[0001] The present invention relates to buildings. [Background technology]

[0002] In recent years, in addition to rooms such as living rooms and dining rooms where family members gather, houses are often provided with highly independent rooms (independent rooms) for use by specific individuals. For example, independent rooms may be used as work rooms (see Patent Documents 1 and 2 below) or as treatment rooms for cohabitants. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-286072 [Patent Document 2] JP 2003-161046 A Summary of the Invention [Problem to be solved by the invention]

[0004] When used as a medical treatment room, it is desirable to control the flow of air to other spaces for sanitary air conditioning management.

[0005] Therefore, the present invention has been made in consideration of the above circumstances, and provides a building that can prevent air from flowing from a specific room into other spaces within the building. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention employs the following means. In other words, the building of the present invention comprises a first room which can directly supply and exhaust air to the outside, a second room adjacent to the first room, and a third room adjacent to the second room, the second room being at a higher positive pressure than the first room and the third room, a first door that can be opened and closed is disposed between the first room and the second room, and an air flow is formed from the second room toward the third room.

[0007] In a building configured in this manner, the second room is at a higher positive pressure than the first room, so when the first fitting connecting the second room and the first room is opened, an airflow (air flow) is formed from the second room to the first room, and air is prevented from flowing from the first room to the second room. Since the second room is at a higher positive pressure than the third room and an airflow is formed from the second room to the third room, the residual air in the second room flows into the third room after the first fitting is closed. This makes it possible to prevent air from flowing from the first room (a specified room) into other spaces such as the second room.

[0008] In addition, in the building of the present invention, a wall is provided around the first room to separate it from other spaces within the building, and the wall may have a wall panel arranged from the floor slab to the ceiling slab, and a sealant arranged between a lower end of the wall panel and the floor slab, and between an upper end of the wall panel and the ceiling slab.

[0009] In a building constructed in this manner, a sealant is placed between the lower end of the wall panel of the wall provided around the first room and the floor slab, and a sealant is placed between the upper end of the wall panel and the ceiling slab. This seals the gaps between the wall panel and the floor slab and between the wall panel and the ceiling slab, making it possible to prevent air from flowing into the first room from places other than the first fixture.

[0010] In addition, the building of the present invention may have a second door that can be opened and closed arranged between the second room and the third room, and the second door may have a ventilation space formed therein that allows air to circulate.

[0011] In a building configured in this manner, a ventilation space is formed in the second fixture that allows air to circulate, so that air from the second room can pass through the ventilation space and flow into the third room.

[0012] In the building according to the present invention, the first fitting may be configured to be capable of sealing off the first room and the second room.

[0013] In a building configured in this manner, the first fitting is configured to be able to seal the first room and the second room, so that when the first fitting is closed, air can be prevented from circulating around the first fitting, etc.

[0014] The building according to the present invention further includes a first air supply and exhaust system for supplying and exhausting air to the first room; The system may further include a second air supply and exhaust system that supplies air to the second room and exhausts air from the third room, and the first air supply and exhaust system and the second air supply and exhaust system may be separate systems.

[0015] In a building configured in this way, the first supply and exhaust system that supplies and exhausts air to the first room and the second supply and exhaust system that supplies air to the second room and exhausts air from the third room are separate systems. This prevents air from the first room from flowing into the second room and the third room.

[0016] In addition, in the building of the present invention, the second supply and exhaust system may be connected to rooms in the building other than the first room, the second room, and the third room, and the second room may be at a higher positive pressure than the other rooms.

[0017] In a building configured in this way, the second air supply and exhaust system is also connected to other rooms in the building, and the second room is set at a higher positive pressure than the other rooms, thereby preventing air from the first room from flowing into the other rooms.

[0018] In addition, in the building of the present invention, the exhaust equipment of the first air supply and exhaust system may exhaust the air in the first room to the outside and have a suppression mechanism that suppresses the exhausted air in the first room from being recirculated within the building.

[0019] In a building configured in this manner, the suppression mechanism exhausts the air in the first room to the outside and suppresses the exhausted air in the first room from being recirculated inside the building. Therefore, if the air in the first room is contaminated, it does not affect the surrounding area of ​​the building and suppresses the contaminated air from being taken in as part of the air supply of the building or other buildings around the building.

[0020] In the building according to the present invention, the first fitting may be the only opening for entering and exiting the first room from within the building.

[0021] In a building configured in this manner, the only opening for entering and exiting the first room is the first fitting, so that the flow of air flowing from inside the building into the first room can be restricted to the opening where the first fitting is installed. Effect of the Invention

[0022] According to the building of the present invention, it is possible to prevent air from flowing from a specific room into other spaces. [Brief description of the drawings]

[0028] A washroom 16 is disposed adjacent to the −Y side of the corridor 12. A bathroom 17 is disposed adjacent to the washroom 16 on the +X side.

[0029] A private room 21 is arranged adjacent to the +Y side of the corridor 12 and on the -X side of the toilet 15. A private room 22 is arranged adjacent to the -Y side of the corridor 12 and on the -X side of the washroom 16. An LDK (living, dining, and kitchen) 23 is arranged on the -X side of the corridor 12.

[0030] A wall (partition wall) W1 is provided between the corridor 12 and the private room 14. A wall (partition wall) W2 is provided between the toilet 15 and the private room 14.

[0031] 2 is an elevation view showing a schematic configuration of the walls W1 and W2. The walls W1 and W2 are collectively referred to as the wall W. As shown in Fig. 2, the wall W has a wall panel 31. The wall panel 31 is formed in a flat plate shape. The plate surface of the wall panel 31 is arranged along a vertical plane. The wall panel 31 is arranged from the floor slab 32 to the ceiling slab 33.

[0032] A small gap is formed between the lower end 31d of the wall panel 31 and the floor slab 32. A sealant 35 is provided between the lower end 31d of the wall panel 31 and the floor slab 32. A small gap is formed between the upper end 31u of the wall panel 31 and the ceiling slab 33. A sealant 35 is provided between the upper end 31u of the wall panel 31 and the ceiling slab 33. The sealant 35 closes the gap and prevents air from flowing through the gap.

[0033] As shown in Fig. 1, a sliding door D1 is provided between the corridor 12 and the front room 13. The sliding door D1 is a one-way sliding door that is movable in the X direction. The sliding door D1 does not have a ventilation space formed therein, unlike the door D2 described later.

[0034] Between the front room 13 and the toilet 15, a door (second fixture) D2 is provided. FIG. 3 is an elevation view showing a schematic configuration of the door D2. As shown in Fig. 3, the door D2 has a door frame 36 and a door body 37. The door frame 36 is a three-sided frame having an upper frame and a pair of vertical frames. The door body 37 is attached to the door frame 36 via hinges (not shown) and is designed to open towards the front room 13.

[0035] The door D2 has a ventilation space that allows air to flow from the front room 13 side to the toilet 15 side. The ventilation space is, for example, a gap (undercut) s1 formed between the floor surface F and the lower end of the door body 37. In addition, an opening such as a louver that penetrates the door body 37 in the plate thickness direction (the direction from the front room 13 side toward the toilet 15 side) may be formed as the ventilation space.

[0036] As shown in FIG. 1, a door (first fitting) D3 is provided between the front room 13 and the private room 14. The door D3 is configured to be able to seal the front room 13 and the private room 14. The door D3 is able to seal the front room 13 and the private room 14 by not forming a ventilation space like the door D2, for example. The only opening for entering and exiting the private room 14 from inside the building 1 is the door D3. As a result, when a resident enters or leaves the private room 14, they must pass through the front room 13 and open the door D3.

[0037] The building 1 is equipped with a first air supply and exhaust system (first air supply and exhaust system) 40, a second air supply and exhaust system (second air supply and exhaust system) 50, and a third air supply and exhaust system 70. The first air supply and exhaust system 40 and the second air supply and exhaust system 50 are separate systems and do not supply or exhaust air to the same room. In Fig. 1, the dashed arrows indicate the air supply paths, and the solid arrows indicate the exhaust paths.

[0038] The first air supply and exhaust system 40 supplies and exhausts air to and from the private room 14. The first air supply and exhaust system 40 has a first air supply facility 41 and a first exhaust facility 46.

[0039] The first air supply equipment 41 has an external air supply port 42. The external air supply port 42 is, for example, provided on an outer wall of the private room 14, and is an air supply register that can adjust the amount of air supplied.

[0040] The first exhaust equipment 46 has an exhaust port 47, a fan 48, and a suppression mechanism 49. The exhaust port 47 is provided, for example, in the ceiling or a wall of the private room 14. The fan 48 is provided, for example, in the attic of the private room 14. A duct 48a connected to the fan 48 is connected to the exhaust port 47 and is also connected to the suppression mechanism 49.

[0041] The suppression mechanism 49 exhausts the air in the individual rooms 14 to the outside via a backflow prevention damper (not shown). The suppression mechanism 49 is configured to suppress the exhausted air in the individual rooms 14 from being recirculated into the building 1. The suppression mechanism 49 may be, for example, a chimney that continues to the rooftop, or a duct that sufficiently protrudes from the exterior wall of the building 1.

[0042] Air outside the building 1 flows into the private room 14 through the external air intake 42. Air inside the private room 14 is forcibly drawn in through the exhaust 47 by the fan 48, passes through the duct 48a, and is exhausted to the outside of the building 1 by the suppression mechanism 49. In this way, the private room 14 is capable of directly supplying and exhausting air to and from the outside of the building 1.

[0043] The second supply and exhaust system 50 supplies and exhausts air to rooms other than the private rooms 14 of the building 1. Specifically, the second supply and exhaust system 50 supplies air to the front room 13, the private rooms 21, 22, and the living / dining / kitchen area 23, and exhausts air from the toilet 15, the washroom 16, the bathroom 17, and the living / dining / kitchen area 23.

[0044] The second air supply and exhaust system 50 has a second air supply facility 52 and a second exhaust facility 61.

[0045] The second air supply equipment 52 has air intakes 53, 54, 55, and 56, a fan 57, and an external air intake 58. The air intake 53 is provided in the front room 13. The air intake 54 is provided in the private room 21. The air intake 55 is provided in the private room 22. The air intake 56 is provided in the living / dining / kitchen area 23. The air intakes 53, 54, 55, and 56 are provided, for example, in the ceiling, floor, wall, etc. of each room. The external air intake 58 is provided in the outer wall of the living / dining / kitchen area 23.

[0046] The fan 57 is provided in the living / dining / kitchen area 23. The fan 57 is provided, for example, above the ceiling of the living / dining / kitchen area 23. The air supply ports 53, 54, 55, 56, the external air supply port 58, and the fan 57 are connected by a duct 59.

[0047] The second exhaust equipment 61 has exhaust ports 62, 63, 64 and a fan 66. The exhaust port 62 is provided in the toilet 15. The exhaust port 63 is provided in the washroom 16. The exhaust port 64 is provided in the bathroom 17. The fan 66 is provided in the ceiling or the like of the bathroom 17. The exhaust ports 62, 63, 64 and the fan 66 are connected by a duct 65. The duct 65 is connected to an external exhaust port (not shown) provided in, for example, an outer wall or the like located on the +X side of the bathroom 17.

[0048] The third air supply and exhaust system 70 has a kitchen air supply and exhaust equipment 71. The kitchen air supply and exhaust equipment 71 is provided in, for example, a kitchen range hood, and simultaneously supplies and exhausts air.

[0049] The kitchen supply and exhaust equipment 71 supplies and exhausts air to and from the living / dining / kitchen area 23, particularly the kitchen area. Air from outside the building 1 passes through external air supply port 58, is forcibly drawn into duct 59 by fan 57, flows into living / dining / kitchen area 23 through air supply port 56, flows into private room 21 through air supply port 54, flows into private room 22 through air supply port 55, and flows into front room 13 through air supply port 53.

[0050] By the fan 66, air in the toilet 15 is drawn in through the exhaust port 62, air in the washroom 16 is drawn in through the exhaust port 63, and air in the bathroom 17 is drawn in through the exhaust port 64, passes through the duct 65, and is exhausted from the external exhaust port.

[0051] The supply and exhaust volumes of the first supply and exhaust system 40 and the second supply and exhaust system 50 are adjusted so that the front room 13 is at a positive pressure (higher air pressure) than the private room 14 and the toilet 15, and is at a positive pressure higher than the other rooms (the washroom 16, the bathroom 17, the private rooms 21, 22, and the living / dining / kitchen area 23) in the building 1. This creates an air flow from the front room 13 toward the toilet 15, and the air in the front room 13 passes through the ventilation space s1 of the door D2 and flows into the toilet 15, and is exhausted to the outside through the exhaust port 62.

[0052] The ventilation rate of the first air supply and exhaust system 40 is set to be greater than the ventilation rate of the second air supply and exhaust system 50.

[0053] In the building 1 configured in this manner, the front room 13 is at a higher positive pressure than the private room 14, so when the door D3 connecting the front room 13 and the private room 14 is opened, an airflow (air flow) is formed from the front room 13 to the private room 14, and air is prevented from flowing from the private room 14 to the front room 13. Since the front room 13 is at a higher positive pressure than the toilet 15 and an airflow is formed from the front room 13 to the toilet 15, after the door D3 is closed, the remaining air in the front room 13 flows into the third room and is prevented from flowing into the corridor 12 adjacent to the front room 13. Therefore, it is possible to prevent air from flowing from the private room 14 (a specified room) into other spaces such as the front room 13.

[0054] Furthermore, a sealant 35 is disposed between the lower end 31d of the wall panel 31 of the wall W provided around the private room 14 and the floor slab 32, and a sealant 35 is disposed between the upper end 31u of the wall panel 31 and the ceiling slab 33. As a result, the gaps between the wall panel 31 and the floor slab 32 and the ceiling slab 33 are sealed, so that air is prevented from flowing into the private room 14 from places other than the door D3. Furthermore, the sound insulation of the private room 14 can be improved.

[0055] In addition, since a ventilation space s1 through which air can flow is formed in the door D2, air in the anteroom 13 can pass through the ventilation space s1 and flow into the toilet 15 even when the door D2 is closed.

[0056] Furthermore, since the door D3 is configured to be able to seal the private room 14 and the anteroom 13, it is possible to prevent air from circulating around the door D3 when the door D3 is closed.

[0057] In addition, the first air supply and exhaust system 40 that supplies and exhausts air to the private room 14 and the second air supply and exhaust system 50 that supplies air to the front room 13 and exhausts air from the toilet 15 are separate systems. Therefore, the air in the private room 14 is prevented from flowing into the front room 13 and the toilet 15.

[0058] The second air supply and exhaust system 50 is also connected to other rooms in the building 1 (the washroom 16, the bathroom 17, the private rooms 21 and 22, and the living / dining / kitchen area 23), and the front room 13 is set to a higher positive pressure than the other rooms. This prevents air from the private room 14 from flowing into the other rooms.

[0059] Furthermore, the suppression mechanism 49 exhausts the air in the private room 14 to the outside via the backflow prevention damper, preventing the exhausted air in the private room 14 from being recirculated back into the building 1. Therefore, for example, if the private room 14 is used for recuperation of a patient with mild infectious disease and the air in the private room 14 is contaminated, it is possible to prevent the surrounding area of ​​the building 1 from being affected and to prevent the contaminated air from being taken in as part of the air supply to the building 1 or other buildings 1 surrounding the building 1.

[0060] In addition, since the only opening for entering and exiting the private room 14 is the door D3, the flow of air flowing from inside the building 1 into the private room 14 can be restricted to the opening where the door D3 is provided.

[0061] The shapes and combinations of the components shown in the above-described embodiment are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0062] For example, the upper and lower ends of the wall panel 31 of the wall W provided around the private room 14 are provided with a sealant 35 to seal the gaps between the wall panel 31 and the floor slab 32 and the ceiling slab 33, but the present invention is not limited to this. The gaps between the wall panel 31 and the floor slab 32 and the ceiling slab 33 do not have to be sealed with the sealant 35.

[0063] Further, the door D2 is formed with the ventilation space s1 through which air can flow, but the present invention is not limited to this. The door D2 does not necessarily have to be formed with the ventilation space s1.

[0064] In addition, the door D3 is configured to be able to seal the private room 14 and the front room 13, but the present invention is not limited to this. The door D3 does not have to be configured to be able to seal the private room 14 and the front room 13.

[0065] In addition, the second air supply and exhaust system 50 is also connected to other rooms in the building 1, and the front room 13 is set to a more positive pressure than the other rooms, but the present invention is not limited to this. The second air supply and exhaust system 50 does not have to be connected to other rooms in the building 1.

[0066] Further, although the second air supply and exhaust system 50 includes the suppression mechanism 49, the present invention is not limited to this. The second air supply and exhaust system 50 does not necessarily have to include the suppression mechanism 49.

[0067] Additionally, wiring and piping that extend from the private room 14 to other spaces in the building 1 may be sealed with a sealant at the boundary between the private room 14 and the other spaces. This prevents air from inside the private room 14 from flowing into the other spaces through the wiring and piping. [Explanation of symbols]
