Description

[Technical Field]

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

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

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-286072 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-161046 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 hygiene reasons.

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

[0006] In order to achieve the above object, the present invention employs the following means. In other words, the house of the present invention comprises a first area having an independent private room that can be supplied with air directly from outside and exhausted to the outside by an exhaust fan, a second area having a common area adjacent to the first area, and a third area having a living room adjacent to the second area, wherein the third area is at a more positive pressure than the first and second areas, and an air flow is formed from the third area toward the second area, and a first door that can be opened and closed is arranged between the first area and the second area, and when the first door is closed, air flow between the first area and the second area is blocked.

[0007] In a house configured in this way, the first zone uses a ventilation method (type 3 ventilation) in which air is directly supplied from outside and exhausted by an exhaust fan, preventing air from the first zone from flowing into the second or third zone. Furthermore, because the third zone has a higher positive pressure than the second zone, an airflow (air flow) is created from the third zone to the second zone, preventing air from flowing from the second zone into the third zone. In other words, air from the first zone can be prevented from flowing into the third zone.

[0008] In addition, the house of the present invention may have a wall around the first area that separates it from other spaces within the house, and the wall may have a wall panel arranged from the floor slab to the ceiling slab, and sealing material arranged between the lower end of the wall panel and the floor slab, and between the upper end of the wall panel and the ceiling slab.

[0009] In a house configured in this way, a sealant is placed between the lower end of the wall panel of the wall provided around the first area and the floor slab, and a sealant is placed between the upper end of the wall panel and the ceiling slab. Therefore, since the gaps between the wall panel and the floor slab and between the wall panel and the ceiling slab are sealed, it is possible to reliably suppress the flow of air between the first area and other areas when the first fitting is closed.

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

[0011] In a house configured in this manner, a ventilation space is formed in the second fixture that allows air to circulate, so that air from the third area can flow into the second area through the ventilation space regardless of whether the fixture is open or closed.

[0012] In the house according to the present invention, the exhaust fan that exhausts the first area and the exhaust fan that exhausts the second area may be a common exhaust fan.

[0013] In a house configured in this way, the number of exhaust fans can be reduced, allowing for cost-effective operation.

[0014] In the house according to the present invention, the opening for entering and exiting the first area may be the first fitting only.

[0015] In a house configured in this manner, the only opening for entering and exiting the first area is the first fixture, so the flow of air flowing in and out of the first area from within the dwelling unit can be restricted to the opening where the first fixture is installed.

[0016] In addition, the house of the present invention may have an external corridor adjacent to the dwelling unit, and the exhaust duct that exhausts air from the first area may extend across the external corridor to the outer wall portion.

[0017] In a house configured in this manner, the exhaust air from the first area can be exhausted outward from the exterior wall, thereby preventing the exhausted air from being re-introduced into the dwelling unit.

[0018] In the house according to the present invention, air may be supplied to the third area using at least an air supply fan.

[0019] In a house configured in this manner, it is easier to maintain a positive pressure in the third area than in the other areas, and it is possible to more reliably prevent air from being drawn in from the second area (and the first area). [Effects of the Invention]

[0020] According to the house of the present invention, it is possible to prevent air from flowing from a specific room into other spaces. [Brief explanation of the drawings]

The entrance hall 11, corridor 12, washroom 16, toilet 17, dressing room 18, and bathroom 19 constitute a second area A2.

[0027] The kitchen 20 is located adjacent to the -X side of the washroom 16. A door D4 is provided between the washroom 16 and the kitchen 20. The living / dining room 21 is located adjacent to the -X side of the kitchen 20. On the +Y side of the living / dining room 21, a workspace 22, a private room 23, and a private room 24 are arranged in this order from the +X side to the -X side. A door D5 is provided between the corridor 12 and the living / dining room 21. The kitchen 20, the living / dining room 21, the workspace 22, the private room 23, and the private room 24 form a third area A3.

[0028] A wall W1 is provided between the first area A1 and the second area A2, and a wall W2 is provided at the boundary between the first area A1 and the third area A3.

[0029] FIG. 2 is an elevation view showing a schematic configuration of walls W1 and W2. Walls W1 and W2 are collectively referred to as wall W. As shown in FIG. 2, wall W has wall panels 31. The wall panels 31 are formed in the shape of flat plates. The plate surfaces of the wall panels 31 are arranged along vertical planes. The wall panels 31 are arranged from the floor slab 32 to the ceiling slab 33.

[0030] 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 it.

[0031] As shown in FIG. 1, door D1 is provided between the corridor 12 and the detached room 14. Door D1 does not have a ventilation space formed therein, unlike doors D2 to D5, which will be described later. In other words, when door D1 is closed, it is configured to be airtight so that air does not circulate between the corridor 12 and the detached room 14. In other words, by closing door D3, it is possible to block the inflow and outflow of air into and out of the detached room 14 from other rooms, and air supply and exhaust to the detached room 14 can all be performed independently.

[0032] A door D2 is provided between the hallway 12 and the washroom 16. A door D3 is provided between the washroom 16 and the toilet 17. A door D4 is provided between the washroom 16 and the kitchen 20. The doors D2, D3, and D4 are all sliding doors. The doors D2, D3, and D4 are provided with undercuts or louvers, allowing air to circulate between the rooms on either side of the doors D2, D3, and D4.

[0033] Door D5 is provided between the hallway 12 and the living / dining room 21. FIG. 3 is an elevation view showing a schematic configuration of door D5. As shown in FIG. 3, door D5 has a door frame 36 and a door body 37. Door frame 36 is a three-sided frame having a top frame and a pair of vertical frames. Door body 37 is attached to door frame 36 via hinges or the like (not shown) and is designed to open toward the living / dining room 21.

[0034] Door D2 has a ventilation space formed therein that allows air to circulate from the living / dining room 21 side to the hallway 12 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. Alternatively, an opening such as a louver that penetrates the door body 37 in the thickness direction (from the living / dining room 21 side toward the hallway 12 side) may be formed as the ventilation space.

[0035] House 1 is equipped with a first air supply and exhaust system 40 and a second air supply and exhaust system 70. First air supply and exhaust system 40 and second air supply and exhaust system 70 do not supply or exhaust air to or from the same room, and are separate systems. In Figure 1, dashed arrows indicate the air supply paths, and solid arrows indicate the exhaust paths.

[0036] The first air supply and exhaust system 40 supplies and exhausts air to and from the first area A1. The first air supply and exhaust system 40 includes a first air supply facility 41 and a first exhaust facility 46.

[0037] The first air supply equipment 41 has an external air supply port 42. The external air supply port 42 is provided, for example, on the outer wall of the independent room 14, and is an air supply register that can adjust the amount of air supplied.

[0038] The first exhaust equipment 46 has an exhaust port 47, an exhaust port 48, and an exhaust port 49. The exhaust port 47 is provided, for example, in the ceiling or wall of the independent room 14. The exhaust port 48 is provided, for example, in the ceiling of the toilet 17. The exhaust port 49 is provided, for example, in the ceiling of the dressing room 18. A duct 50 is connected to the exhaust port 47. The duct 50 is arranged in the ceiling and connected to an exhaust fan 51 arranged in the ceiling of the bathroom 19. A duct 52 is connected to the exhaust port 48. The duct 52 is arranged in the ceiling and connected to an exhaust fan 51 arranged in the ceiling of the bathroom 19. A duct 53 is connected to the exhaust port 49. The duct 53 is arranged in the ceiling and connected to the exhaust fan 51 arranged in the ceiling of the bathroom 19. Air is supplied to the hallway 12 and the washroom 16 from the living / dining room 21 and the kitchen 20 through the ventilation spaces of doors D4 and D5. The exhaust fan 51 is, for example, a 24-hour mechanical ventilation fan for sick house syndrome.

[0039] An exhaust duct 54 is connected to the exhaust fan 51. The exhaust duct 54 is led from the exhaust fan 51 to the outside of the dwelling, is arranged so as to cross the ceiling of the external corridor 55, and is configured to be exhausted from an outer wall 56 of the house 1.

[0040] A backflow prevention damper (not shown) may be provided in the exhaust duct 53. The provision of the backflow prevention damper is configured to prevent the exhausted air in the detached room 14 from being recirculated within the house 1.

[0041] The first area A1 supplies air to the inside of the detached room 14 through the external air intake port 42. The air inside the detached room 14 is forcibly drawn in through the exhaust port 47 by the exhaust fan 51 and exhausted to the outside of the house 1 through the ducts 50 and 54. In this way, the detached room 14 can directly supply and exhaust air to and from the outside of the house 1.

[0042] The second area A2 supplies air from the kitchen 20 to the washroom 16 through the ventilation space of door D4, and from the living / dining room 21 to the hallway 12 through door D5. The air supplied to the hallway 12 flows into the washroom 16 through the ventilation space of door D2. A portion of the air that flows into the washroom 16 flows into the toilet 17 through the ventilation space of door D3. The air that flows into the toilet 17 is exhausted to the outside through exhaust port 48. A portion of the air that flows into the washroom 16 flows into the dressing room 18. The air that flows into the dressing room 18 is exhausted to the outside through exhaust port 49. A portion of the air that flows into the washroom 16 flows into the bathroom 19. The air that flows into the bathroom 19 is exhausted to the outside through an exhaust port (not shown) provided in fan 51.

[0043] The first exhaust equipment 46 is made up of exhaust ports 47, 48, and 49, ducts 50, 52, and 53, an exhaust fan 51, and an exhaust duct 54.

[0044] The second 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, for example, in a range hood of the kitchen 20, and serves to simultaneously supply and exhaust air. The second air supply and exhaust system 70 of this embodiment is further provided with an air supply fan 72 for constantly supplying air to the kitchen 20.

[0045] The second air supply and exhaust system 70 supplies air not only to the kitchen 20 area, but also to the living-dining area 21. External air supply vents 73 and 74 are provided on the wall facing the veranda 61 of the house 1. The external air supply vent 73 is provided on the wall facing the living-dining area 21. The external air supply vent 74 is provided on the wall facing the private room 24. In other words, air is supplied to the second area A2 via the third area A3 and doors D4, D5, etc. from the air supply fan 72 and the external air supply vents 73 and 74.

[0046] Kitchen air supply and exhaust system 71 has kitchen air supply system 75 and kitchen exhaust system 76. Kitchen air supply system 75 takes in outside air from balcony 61 and is connected to air supply fan 72 via duct 77 disposed, for example, in the ceiling. Air supply duct 78 is connected to air supply fan 72. Air supply duct 78 is connected to air supply port 79 of a range hood provided in kitchen 20, and air is supplied into the room from air supply port 79.

[0047] The kitchen exhaust equipment 76 has an exhaust port 80 provided in the range hood of the kitchen 20. An exhaust fan (not shown) is connected to the exhaust port 80. A duct 81 is connected to the exhaust fan. The duct 81 is disposed, for example, in the ceiling of the living / dining room 21, and is configured to exhaust air to the balcony 61.

[0048] The kitchen air supply equipment 75 is equipped with an air supply fan 72 and an intake / exhaust type range hood, but it may also be configured so that the air supply fan 72 is not provided and a forced air supply type range hood is used to constantly supply air from the kitchen 20 to the living / dining room 21.

[0049] The excess air supplied to the third area A3 flows into the second area A2 through the ventilation spaces of the doors D4 and D5. In other words, the third area A3 is maintained at a higher positive pressure than the second area A2, which prevents air from flowing from the second area A2 into the third area A3.

[0050] Here, an example of the ventilation air volume to each room will be described. The exhaust air volume of the independent room 14 in the first area A1 is 31.5 m 3 / h, 45.5m in strong wind operation mode 3 The exhaust air volume of the toilet 17 and the changing room 18 in the second area A2 is 41 m / h in 24-hour ventilation mode. 3 / h, 61.5m in strong wind operation mode 3 / h, and the exhaust air volume of bathroom 19 is 47.5 m in 24-hour ventilation mode. 3 / h, 71m in strong wind operation mode 3In other words, the total exhaust air volume of the second area A2 is 88.5 m / h in 24-hour ventilation mode. 3 / h, 132.5m in strong wind operation mode 3 / h. The normal air supply volume for the third area A3 is 180 m 3 / h, and when using the kitchen range hood 20, it is 600m 3 / h (constant ventilation 180m 3 / h + kitchen air supply 420m 3 / h). Since the range hood has the same intake and exhaust air volume, the kitchen exhaust air volume is 420 m 3 / h.

[0051] In other words, the ventilation rate in the first zone A1 is approximately 1.2 times / h in 24-hour ventilation mode, and the ventilation rates in the second zone A2 and the third zone A3 are approximately 0.5 times / h in 24-hour ventilation mode. In the strong wind operation mode, an even higher ventilation rate can be ensured.

[0052] Next, we will explain the flow of people within a residence when a family member is infected with an infectious disease. As shown in Figure 4, after returning home, a non-infected person disinfects their hands with alcohol at the entrance 11 (Step 1). After disinfecting, they take off their jackets and hang them on a coat rack, for example, in the hallway 12 (Step 2). They then pass through door D2 and enter the bathroom 16 (Step 3). Door D2 is designed to open and close without needing to grip the handle, for example. They wash their hands in the bathroom 16 (Step 4) and change into their loungewear in the bathroom 16 (Step 5). They then pass through doors D2 and D5 and enter the living / dining room 21 (Steps 6 and 7). Alternatively, they can open door D4 and enter the living / dining room 21 via the kitchen 20.

[0053] As shown in Figure 5, an infected person lives in an individual room 14. The following describes the route an infected person takes to go to the toilet 17, etc. The infected person opens door D1 and exits into the hallway 12 (Step 1). Door D1 may be equipped with a doorknob that does not require gripping a handle when opening or closing. The infected person passes through door D2 from the hallway 12 and enters the washroom 16 (Step 2). Door D2 may also be designed to open and close without gripping a handle. The infected person washes their hands in the washroom 16 (Step 3). Door D3 is opened to enter the toilet 17 and relieves themselves (Step 4). Door D3 may also be designed to open and close without gripping a handle. Before leaving the toilet 17, the infected person disinfects themselves with disinfectant provided inside the toilet 17 (Step 5). Door D3 is opened to return to the washroom 16 and washes their hands (Step 6). The infected person passes through door D2 and exits into the hallway 12 (Step 7), and then passes through door D1 to return to the individual room 14 (Step 8). With this configuration, even if an infected person uses the common area of ​​the second area A2, infection of non-infected people can be prevented as much as possible.

[0054] According to this embodiment, the house 1 includes a first area A1 having an independent room 14 that can be directly supplied with air from the outside and exhausted to the outside by an exhaust fan 51, a second area A2 having common areas such as a bathroom 16 adjacent to the first area A1, and a third area A3 having a living / dining room 21 adjacent to the second area A2. The third area A3 is under a higher pressure than the first and second areas A1 and A2, creating an airflow from the third area A3 toward the second area A2. A door (first fixture) D1 is located between the first area A1 and the second area A2, and when the door D1 is closed, air circulation between the first area A1 and the second area A2 is blocked. In this house 1, the first area A1 uses a ventilation method (type 3 ventilation) in which air is directly supplied from the outside and exhausted by the exhaust fan 51, preventing air from the first area A1 from flowing into the second area A2 or the third area A3. Furthermore, because the third area A3 has a more positive pressure than the second area A2, an airflow (air flow) is formed from the third area A3 to the second area A2, and air is prevented from flowing from the second area A2 into the third area A3. In other words, air is prevented from flowing from the third area A3 into the first area A1.

[0055] Furthermore, a wall W (W1, W2) is provided around the first area A1 of the house 1 to separate it from other spaces within the dwelling unit. The wall W has a wall panel 31 arranged from a floor slab 32 to a ceiling slab 33, and a sealant 35 arranged between a lower end 31d of the wall panel 31 and the floor slab 32 and between an upper end 31u of the wall panel 31 and the ceiling slab 33. In the house 1 configured in this manner, a sealant 35 is arranged between the lower end 31d of the wall panel 31 of the wall W provided around the first area A1 and the floor slab 32, and a sealant 35 is arranged between the upper end 31u of the wall panel 31 and the ceiling slab 33. Therefore, gaps between the wall panel 31 and the floor slab 32 and the ceiling slab 33 are sealed, thereby reliably suppressing air flow between the first area A1 and the other areas A2 and A3 when the door D1 is closed.

[0056] Furthermore, an openable door (second fitting) D4 is disposed between the second area A2 and the third area A3, and a ventilation space through which air can circulate is formed in the door D4. In the house 1 configured in this manner, the ventilation space through which air can circulate is formed in the door D4, so that air from the third area A3 can flow into the second area A2 through the ventilation space regardless of whether the door D4 is open or closed.

[0057] Furthermore, the exhaust from the first area A1 and the exhaust from the second area A2 are configured to be exhausted by a common exhaust fan 51. In a house 1 configured in this manner, the number of exhaust fans can be reduced, thereby reducing costs and enabling efficient maintenance.

[0058] Furthermore, the only opening for entering and exiting the first area A1 is the door D1. In the house 1 configured in this manner, the only opening for entering and exiting the first area A1 is the door D1, so the flow of air flowing in and out of the first area A1 from inside the dwelling unit can be limited to the opening where the door D1 is installed.

[0059] In addition, an external corridor 55 is provided adjacent to the dwelling unit, and an exhaust duct 54 that exhausts air from the first area A1 extends across the external corridor 55 to an exterior wall 56. In a house 1 configured in this manner, the exhaust air from the first area A1 can be exhausted outward from the exterior wall 56, preventing the exhausted air from being re-introduced into the dwelling unit.

[0060] Additionally, air is supplied to the third area A3 using at least the air supply fan 72. In a house 1 configured in this manner, the third area A3 can be maintained at a positive pressure more easily than the other areas, and drawing air from the second area A2 (and the first area A1) can be more reliably prevented.

[0061] According to this embodiment, it is possible to reduce the risk of family members who have been infected with or are suspected of being infected with an infectious disease such as the new coronavirus, influenza, or norovirus spreading the infection within the home.

[0062] 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., within the scope of the present invention.

[0063] For example, sealants 35 are provided at the upper and lower ends of the wall panels 31 of the wall W provided around the independent room 14 to seal the gaps between the wall panels 31 and the floor slab 32 and ceiling slab 33, but the present invention is not limited to this. The gaps between the wall panels 31 and the floor slab 32 and ceiling slab 33 do not have to be sealed with the sealants 35.

[0064] Furthermore, the door D5 has a gap (ventilation space) s1 formed therein that allows air to circulate, but the present invention is not limited to this. The door D5 does not necessarily have to have the gap s1 formed therein.

[0065] In addition, a sealable door D1 is provided between the corridor 12 and the separate room 14, but a front room may also be provided between the corridor 12 and the separate room 14.

[0066] Additionally, wiring and piping that extend from the detached room 14 to other spaces in the house 1 may be sealed with a sealant at the boundary between the detached room 14 and the other spaces. This prevents air from inside the detached room 14 from flowing into other spaces via the wiring and piping.

[0067] The plan for House 1 is just an example, and other plans may be used. A zoning plan that limits areas where infection is a concern should be created. Also, a ventilation plan that prevents air from flowing back from areas where infection is a concern to other rooms should be created. [Explanation of symbols]
