The blocking means 45 includes, for example, a peripheral edge of the surface of the closed door 44 on the toilet room 5 side, and a rubber 46 provided on the peripheral edge of the door frame 43 so as to be in contact with the peripheral edge while maintaining an airtight state. Is done. Therefore, when the door 44 is closed, the air flow between the interior of the toilet room 5 and the corridor 6 via the opening 42 is blocked by the blocking means 45.
When the air flow path between the interior of the toilet room 5 and the corridor 6 via the opening 42 is blocked by the blocking means 45, the air flow to the toilet room 5 is connected to the air supply hole 32 and the exhaust device. This is possible only via the 31A mounting hole.

トイレ室5以外の部屋、即ち、特定の部屋以外の部屋(特定の部屋以外の建物内部)としての居室7、納戸b、居室(和室)d、リビングダイニングeは、空気取込孔51を備える。空気取込孔51は、特定の部屋以外の部屋の室内と床下空間35とに跨って貫通する。空気取込孔51は、例えば特定の部屋以外の部屋の床板13の端面13Aが壁2や2Aや2Bの内面2Aより離れて設置されたことによって床板13の端面13Aと壁の内面2Aとの間に設けられた隙間Sにより形成される。よって、隙間Sが空気取込孔51として機能するとともに、隙間Sにより、床板13の端面13Aと壁の内面2Aとが縁の切れた状態となるので、床板13の端面13Aと壁の内面2Aとが接触することによるこすれ音の発生をなくすことができる。また、床板13にドリルなどで孔を形成することなく空気取込孔51を形成できるので、空気取込孔51の形成作業が容易となり、かつ、床1の見栄えをよくできる。   The room 7 other than the toilet room 5, that is, the room 7 as a room other than the specific room (the interior of the building other than the specific room), the storage room b, the living room (Japanese room) d, and the living dining room e include an air intake hole 51. . The air intake hole 51 penetrates the room other than the specific room and the underfloor space 35. The air intake hole 51 is formed, for example, between the end surface 13A of the floor plate 13 and the inner surface 2A of the wall by setting the end surface 13A of the floor plate 13 of a room other than a specific room apart from the inner surfaces 2A of the walls 2, 2A, and 2B. It is formed by a gap S provided therebetween. Accordingly, the gap S functions as the air intake hole 51, and the gap S causes the end surface 13A of the floor board 13 and the inner surface 2A of the wall to be cut off from each other. Therefore, the end surface 13A of the floor board 13 and the inner surface 2A of the wall The generation of rubbing noise due to contact with can be eliminated. Moreover, since the air intake hole 51 can be formed without forming a hole in the floor board 13 with a drill or the like, the work of forming the air intake hole 51 is facilitated, and the appearance of the floor 1 can be improved.

最良の形態1によれば、遮断手段45が、開口部42を経由するトイレ室5の室内と廊下6との間の空気の流通経路を遮断することにより、アンダーカットのような物理的な開口部がなくなって、遮音性能が向上するので、トイレ室5の室内で発生した音の廊下6への透過量を少なくできるとともに、開口部42を経由するトイレ室5の室内と廊下6との間の空気の流通経路が遮断手段45により遮断された場合でも、排気装置31Aの駆動によりトイレ室5の室内が負圧になると、特定の部屋以外の部屋としての居室7、納戸b、居室(和室)d、リビングダイニングeの室内から空気が、空気取込孔51、床下空間35、空気供給孔32により形成される空気流通経路60を経由してトイレ室5の室内に供給されるため、トイレ室5の換気を効率的に行える。   According to the best mode 1, the blocking means 45 blocks the air flow path between the interior of the toilet room 5 and the corridor 6 via the opening 42, thereby providing a physical opening such as an undercut. Since the sound insulation performance is improved by eliminating the portion, the amount of sound generated in the room of the toilet room 5 through the hallway 6 can be reduced and between the room of the toilet room 5 via the opening 42 and the hallway 6. Even when the air flow path is blocked by the shut-off means 45, if the interior of the toilet room 5 becomes negative pressure due to the drive of the exhaust device 31A, the room 7, the storage room b, and the room (Japanese-style room) as a room other than the specific room D) Since the air is supplied from the room of the living dining room e to the room of the toilet room 5 through the air flow path 60 formed by the air intake hole 51, the underfloor space 35, and the air supply hole 32, the toilet Change room 5 Efficiently carried out.

つまり、従来は、トイレ室の出入口のドアの下部に換気のための空気流通口(アンダーカット)を設けていたので、ドアが閉められた場合でも、当該空気流通口を経由してトイレ室の室内で発生した音が空気流通口を経由して廊下に伝播してしまったが、最良の形態1によれば、遮断手段45を備えたので、トイレ室5の室内で発生した音の廊下6への透過量を少なくできるとともに、排気装置31Aと空気流通経路60とを備えたので、トイレ室5の室内の換気を効率的に行えるという効果が得られる。   In other words, conventionally, an air circulation port (undercut) for ventilation is provided at the lower part of the door of the toilet room, so even when the door is closed, the toilet room is connected via the air circulation port. The sound generated in the room has propagated to the corridor via the air circulation port. However, according to the best mode 1, since the blocking means 45 is provided, the sound corridor 6 generated in the room of the toilet room 5 is provided. Since the exhaust device 31A and the air flow path 60 are provided, the ventilation of the toilet room 5 can be efficiently performed.

尚、空気取込孔51は、特定の部屋以外の建物内部の1つ以上の区画領域から床下空間13に通じるように設ければよい。例えば、床下空間13と特定の部屋以外の建物内部としての廊下6とに跨って貫通する空気取込孔51のみを設けるようにしてもよい。   In addition, what is necessary is just to provide the air intake hole 51 so that it may lead to the underfloor space 13 from one or more division area | regions inside buildings other than a specific room. For example, you may make it provide only the air intake hole 51 penetrated ranging over the underfloor space 13 and the corridor 6 as the inside of buildings other than a specific room.
