Based on the pressures measured by the aisle pressure sensor 37a, the living room pressure sensor 37c, and the lobby pressure sensor 37b, the control unit 38 controls the operation of the supply air fan 31, each supply air damper 33, the exhaust fan 34, and each exhaust damper 36, and automatically adjusts the pressure in the aisle 7, the lobby space S1, and the living room space S2.

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 the living space S2. Next, the main door 8b is closed to separate the corridor 7 from the lobby space S1. The lobby partition door 15 is also closed to separate the lobby space S1 from the living space S2. This isolates the infected person in the living space S2. The infected person will live in the 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 isolation.

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

When the infected person finishes their meal, 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 lobby space S1 to their original separated state, and the lobby space S1 to its original separated state.

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 aisle pressure sensor 37a measures the pressure in the aisle 7. Information about the pressure in the aisle 7 is sent to the control unit 38. The lobby pressure sensor 37b measures the pressure in the lobby space S1. Information about 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 about the pressure in the living room space S2 is sent to the control unit 38.

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

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

(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 positioning 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 positioning 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.

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

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 float 1 is provided that can reliably suppress the movement of air containing viruses and sufficiently achieve infection control measures.

In this embodiment, the lobby partition door 15 can be opened and closed using 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 improves the convenience of the main room 8 while keeping costs down.

In this embodiment, the door frame 40 is provided with a gasket 17 that closes the gap between the lobby partition door 15 and the door frame 40 along the side edge of the lobby partition door 15 at the first position P1. This effectively prevents air from moving from the living space S2 into the lobby space S1 and the aisle 7 through the gap between the lobby partition door 15 and the door frame 40 when the living space S2 and the lobby space S1 are separated. 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 partition door 15. Therefore, when an infected person is isolated in the living space S2, it is possible to prevent virus-containing air from moving from the living space S2 to the outside. This more reliably prevents the virus from infecting others.

In this embodiment, a folding table 14 is provided in the lobby space S1. As a result, when dividing the living space S2 and the lobby space S1, supplies brought into the lobby space S1 from the corridor 7 can be placed on the table 14, 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 makes it possible to prevent 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.

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 pressure 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 the living room space S2 can be maintained lower than the pressure in the lobby space S1 and aisle 7. Therefore, if an infected person is isolated in the living room space S2, even if the lobby partition door 15 is temporarily opened, it is possible to prevent virus-containing air from moving outside from the living room space S2. This more reliably prevents the virus from infecting others.

In this embodiment, a window 18 is provided on the wall 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.

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

Next, a modified example will be described. The lobby compartment 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, the lobby partition door 15 has a built-in door control unit and a locking mechanism. When the lobby space S1 and the living space S2 are separated by the lobby partition door 15 as an infection control measure, if the pressure in the lobby space S1 is lower than the pressure in the living space S2, the control unit 38 sends a signal to the door control unit of the lobby partition door 15. The door control unit receiving the signal sends a command to the locking mechanism of the lobby partition door 15, and the lobby partition door 15 is locked by the locking mechanism. This maintains the closed state of the lobby partition door 15. If the pressure in the lobby space S1 becomes higher than the pressure in the living space S2, the control unit 38 sends a signal to the door control unit of the lobby partition door 15, and the door control unit causes the locking mechanism to unlock the lobby partition door 15.
