[0032] (Water-related spaces) The bathroom space S3 is provided with a bathtub 27, a shower (not shown), a toilet 28, and a hand washing basin 29.

[0033] The bathtub 27 is disposed in a corner on one side in the first direction D1 and on one side in the second direction D2 of the bathroom space S3. The bathtub 27 is equipped with a shower. The toilet 28 is arranged on one side of the bathroom space S3 in the first direction D1, alongside the bathtub 27 in the second direction D2. The hand-washing basin 29 is disposed on the other side in the first direction D1 of the toilet 28. The hand-washing basin 29 is attached to the wall surface 8a on the other side in the second direction D2 of the main room 8. A pressure adjusting section 30 is provided to adjust the pressure in the passage 7 and each space described above.

[0034] (Pressure adjustment section) Pressure adjustment unit 30 adjusts the pressure in passage 7, lobby space S1, and living space S2 so that the pressure in living space S2 is lower than the pressure in lobby space S1 and passage 7. Pressure adjustment unit 30 includes an air supply fan 31, an air supply duct 32, an air supply damper 33, an exhaust fan 34, an exhaust duct 35, an exhaust damper 36, a pressure sensor 37, and a control unit 38.

[0035] The air supply fan 31 is provided outside the passage 7 and the main room 8. One air supply duct 32 is provided for each of the passageway 7, the lobby space S1, and the living space S2. Each air supply duct 32 is connected to an air supply fan 31 by an air supply line 39a. Air blown by the air supply fan 31 is supplied from each air supply duct 32 to the passageway 7 and each space through the air supply line 39a. An air supply damper 33 is provided upstream of each air supply duct 32. The air supply damper 33 is provided so as to be able to open and close the air supply line 39a. The opening degree of the air supply damper 33 is adjustable.

[0036] Hereinafter, the air supply duct 32 in the passageway 7 will be referred to as the "passageway air supply duct 32a," the air supply duct 32 in the lobby space S1 will be referred to as the "lobby air supply duct 32b," and the air supply duct 32 in the living room space S2 will be referred to as the "living room air supply duct 32c." Additionally, the air supply damper 33 upstream of the passageway air supply duct 32a will be referred to as the "passageway air supply damper 33a," the air supply damper 33 upstream of the lobby air supply duct 32b will be referred to as the "lobby air supply damper 33b," and the air supply damper 33 upstream of the living room air supply duct 32c will be referred to as the "living room air supply damper 33c."

[0037] An exhaust fan 34 is provided outside the passageway 7 and the main chamber 8. One exhaust duct 35 is provided in each of the passageway 7, the lobby space S1, and the living space S2. Each exhaust duct 35 is connected to an exhaust fan 34 by an exhaust line 39b. When the exhaust fan 34 is operated, air in the passageway 7 and each space is exhausted from each exhaust duct 35 through the exhaust line 39b to the outside. An exhaust damper 36 is provided downstream of each exhaust duct 35. The exhaust damper 36 is provided so as to be able to open and close the exhaust line 39b. The opening degree of the exhaust damper 36 is adjustable.

[0038] Hereinafter, the exhaust duct 35 in the passage 7 will be referred to as the "passageway exhaust duct 35a," the exhaust duct 35 in the lobby space S1 will be referred to as the "lobby exhaust duct 35b," and the exhaust duct 35 in the living room space S2 will be referred to as the "room exhaust duct 35c." Additionally, the exhaust damper 36 downstream of the passageway exhaust duct 35a will be referred to as the "passageway exhaust damper 36a," the exhaust damper 36 downstream of the lobby exhaust duct 35b will be referred to as the "lobby exhaust damper 36b," and the exhaust damper 36 downstream of the living room exhaust duct 35c will be referred to as the "room exhaust damper 36c."

[0039] (Pressure sensor) The pressure sensors 37 are arranged one each in the passage 7, the lobby space S1, and the living space S2. Hereinafter, the pressure sensor 37 in the passage 7 will be referred to as the "passage pressure sensor 37a," the pressure sensor 37 in the lobby space S1 will be referred to as the "lobby pressure sensor 37b," and the pressure sensor 37 in the living room space S2 will be referred to as the "living room pressure sensor 37c." The passage pressure sensor 37a measures the pressure in the passage 7, the lobby pressure sensor 37b measures the pressure in the lobby space S1, and the living room pressure sensor 37c measures the pressure in the living room space S2.

[0040] (Control unit) The control unit 38 is provided outside the passage 7 and the main chamber 8. Control unit 38 is electrically connected to supply air fan 31, each supply air damper 33, exhaust fan 34, each exhaust damper 36, and each pressure sensor 37. Based on the pressures measured by aisle pressure sensor 37a, living room pressure sensor 37c, and lobby pressure sensor 37b, control unit 38 controls the operation of supply air fan 31, each supply air damper 33, exhaust fan 34, and each exhaust damper 36, and automatically adjusts the pressure in aisle 7, lobby space S1, and living room space S2.

[0041] A method for isolating a virus-infected person in the living space S2 to prevent the spread of infection will be described below with reference to FIG. First, the infected person is moved to living space S2. Next, main door 8b is closed to separate corridor 7 from lobby space S1. Lobby partition door 15 is also closed to separate lobby space S1 from living space S2. This isolates the infected person in living space S2. The infected person will live in living space S2 until the risk of infection to others has sufficiently decreased. The bathroom compartment door 26 can be freely opened and closed by the infected person, allowing them to take a bath, defecate, etc. without going outside during quarantine.

[0042] Necessary supplies are carried into the lobby space S1 through the passage 7, and from the lobby space S1 into the living space S2. Below, we will explain the procedure for providing meals to an infected person, for example. First, a crew member opens main door 8b and carries a meal from the aisle 7 into lobby space S1. Next, the crew member assembles folding table 14 and places the meal on table 14. After that, the crew member goes out to the aisle 7 and closes main door 8b. Once main door 8b is closed, the infected person opens lobby section door 15 and carries the meal from lobby space S1 into living space S2. The infected person closes lobby section door 15 and eats the meal in living space S2.

[0043] When the infected person has finished eating, they open the lobby compartment door 15 and return the dishes to the table 14. They then return to the living space S2 and close the lobby compartment door 15. Once the lobby compartment door 15 is closed, the crew member opens the main door 8b, enters the lobby space S1, and carries the dishes out to the aisle 7. The crew member then closes the main door 8b, returning the living space S2 and the lobby space S1 to their original separated state, and the lobby space S1 and the aisle 7 to their original separated state.

[0044] Furthermore, the pressure in the living space S2 is maintained by the pressure adjusting unit 30 so as to be lower than the pressure in the lobby space S1 and the passage 7. The operation of the pressure adjusting unit 30 will now be described. The passageway pressure sensor 37a measures the pressure in the passageway 7. Information on the pressure in the passageway 7 is sent to the control unit 38. The lobby pressure sensor 37b measures the pressure in the lobby space S1. Information on the pressure in the lobby space S1 is sent to the control unit 38. The living room pressure sensor 37c measures the pressure in the living room space S2. Information on the pressure in the living room space S2 is sent to the control unit 38.

[0045] Based on information about the pressure in the passageway 7 and each space, the control unit 38 adjusts the operation of the air supply fan 31 and the exhaust fan 34 and the opening degree of each air supply damper 33 and each exhaust damper 36. This automatically adjusts the pressure in the living space S2 to be lower than the pressure in the lobby space S1 and the passageway 7. The pressure in the lobby space S1 may be lower than the pressure in the passageway 7 or may be equal to the pressure in the passageway 7.

[0046] Due to the pressure difference between the living space S2 and the lobby space S1 and the passageway 7, even if the lobby partition door 15 is temporarily opened, the movement of virus-containing air in the living space S2 is suppressed.

[0047] (Action and effect) The floating body 1 of this embodiment has the following advantages. In this embodiment, the floating body 1 is equipped with a lobby partition door 15 that can be opened and closed between a first position P1 that divides the main room 8 into a lobby space S1 on the aisle 7 side and a living space S2 at the rear, and an open position P2 that opens the lobby space S1 and the living space S2 and follows the wall surface 8a of the main room 8. Therefore, by placing the lobby partition door 15 in the open position P2, the living space S2 and the lobby space S1 can be integrated. Note that, because the lobby partition door 15 follows the wall surface 8a in the open position P2, it does not interfere with movement between the living space S2 and the lobby space S1. Furthermore, by placing the lobby partition door 15 in the first position P1, the living space S2 and the lobby space S1 can be used separately. In this way, the use type of the space can be changed depending on the situation.

[0048] For example, if there is no need to isolate an infected person in living space S2, lobby partition door 15 is placed in open position P2 to integrate living space S2 and lobby space S1. When lobby partition door 15 is open, only the air supply duct 32 and exhaust duct 35 of living space S2 may be used, only the air supply duct 32 and exhaust duct 35 of lobby space S1 may be used, or the air supply duct 32 and exhaust duct 35 of both living space S2 and lobby space S1 may be used. Furthermore, if there is a need to isolate an infected person in living space S2, lobby partition door 15 may be placed in first position P1 to prevent virus-laden air from moving from living space S2 to lobby space S1.

[0049] The floating body 1 further includes a pressure adjusting unit 30 that adjusts the pressure in the passage 7, the lobby space S1, and the living space S2 so that the pressure in the living space S2 is lower than the pressure in the lobby space S1 and the passage 7. By making the pressure in the living space S2 lower than the pressure in the lobby space S1 and the passage 7, even if the lobby partition door 15 is temporarily opened, the pressure difference between the living space S2 and the lobby space S1 can prevent virus-laden air in the living space S2 from moving to the lobby space S1 and the passage 7. As described above, according to this embodiment, a floating body 1 is provided that can reliably suppress the movement of air containing viruses and sufficiently achieve infection control measures.

[0050] In this embodiment, the lobby partition door 15 can be opened and closed by means of a hinge 16. This allows the lobby partition door 15 to be positioned along the wall surface 8a of the main room 8 with a simple configuration when the living space S2 is open. This therefore makes it possible to improve the convenience of the main room 8 while keeping costs down.

[0051] In this embodiment, the door frame 40 is provided with a gasket 17 along the side edge of the lobby section door 15 at the first position P1, sealing the gap between the lobby section door 15 and the door frame 40. This effectively prevents air in the living space S2 from migrating through the gap between the lobby section door 15 and the door frame 40 to the lobby space S1 and the passageway 7 when the living space S2 is separated from the lobby space S1. Furthermore, because the lower gasket 17 is easily deformed, it is possible to prevent the sealing function of the lower gasket 17 from being weakened by the load it receives from the lobby section door 15. Therefore, when an infected person is isolated in the living space S2, it is possible to prevent virus-containing air from migrating from the living space S2 to the outside. This more reliably prevents the virus from infecting others.

[0052] In this embodiment, a folding table 14 is provided in the lobby space S1. This allows supplies brought into the lobby space S1 from the corridor 7 to be placed on the table 14 when dividing the living space S2 and the lobby space S1, and then the living space S2 can be opened and the supplies on the table 14 can be brought into the living space S2. This prevents the virus from spreading to others when providing necessary supplies to an infected person. Furthermore, the table 14 can be folded up when not in use. This improves the convenience of the main room 8.

[0053] In this embodiment, the pressure adjustment unit 30 automatically adjusts the pressure in the aisle 7, lobby space S1, and living space S2 based on the pressures measured by the aisle pressure sensor 37a, living room pressure sensor 37c, and lobby pressure sensor 37b. This allows the pressure in the aisle 7, lobby space S1, and living room space S2 to be automatically controlled based on the pressure in each space. Therefore, even if the pressure in each space fluctuates, the pressure in living room space S2 can be maintained lower than the pressure in the lobby space S1 and aisle 7. Therefore, even if an infected person is isolated in living room space S2 and the lobby partition door 15 is temporarily opened, the movement of virus-laden air from living room space S2 to the outside can be prevented. This more reliably prevents the virus from infecting others.

[0054] In this embodiment, a window 18 is provided on the wall surface 8a of the living space S2. This allows an infected person in the living space S2 to see the view outside the main room 8 without leaving the living space S2. In addition, with the living space S2 and the lobby space S1 separated, the living space S2 can be observed from the outside. Therefore, if an infected person is isolated in the living space S2, the condition of the infected person can be observed without entering the living space S2.

[0055] In this embodiment, a viewing window 15a is provided in the lobby partition door 15. This allows the situation inside the living space S2 to be checked from the lobby space S1 through the viewing window 15a.

[0056] Next, a modified example will be described. The lobby section door 15 may be provided so as to be linked to the control unit 38. Specifically, the floating body 1 may be configured as follows. For example, lobby section door 15 has a built-in door control unit and a locking mechanism. When lobby section door 15 separates lobby space S1 and living space S2 as an infection control measure, if the pressure in lobby space S1 is lower than the pressure in living space S2, control unit 38 sends a signal to the door control unit of lobby section door 15. The door control unit receives the signal and sends a command to the locking mechanism of lobby section door 15, which locks lobby section door 15. This keeps lobby section door 15 in a closed state. If the pressure in lobby space S1 becomes higher than the pressure in living space S2, control unit 38 sends a signal to the door control unit of lobby section door 15, which causes the locking mechanism to unlock lobby section door 15.

[0057] (Other embodiments) The above describes in detail the embodiments of the present disclosure with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes and the like are also included within the scope that does not deviate from the gist of the present disclosure. In the above embodiment, the main room 8 is divided into the living space S2, the lobby space S1, and the bathroom space S3, but this is not limited to this. The main room 8 may be divided into the living space S2 and the lobby space S1 without the bathroom space S3.

[0058] In the above embodiment, the floating body 1 is provided with a wardrobe 19, a bed 20, a chair 22, a desk 21, a chest of drawers 23, a television 24, a bathtub 27, a shower (not shown), a toilet 28, and a hand washing basin 29 in the main room 8, but the furniture and fixtures in the main room 8 can be changed as appropriate. For example, the wardrobe 19 and the bed 20 do not have to be provided in the main room 8.
