For maintenance and the like, a hinged door 22 is attached to one side surface portion 16, and an opening 24 is formed at a lower portion of the hinged door 22 to suck air from an air inlet of the air conditioner main body 30.

A bottom portion 18 is formed at the lower end of the step portion 12, the rear portion 14, and both side portions 16, 16 to close the bottom opening, and the space surrounded by these members becomes a machine room 20, The air conditioner body 30 is housed in the room 20. The air conditioner main body 30 has a structure shown in FIG.
As shown in FIG. 7, an indoor air intake port 32, an outdoor air intake port 34, a blow port 36, and an exhaust port 38 are formed, and a duct pipe is formed from these to a predetermined location.

This embodiment is configured as described above, and a state in which the stair unit 10 according to the embodiment is installed in a building will be described with reference to FIG.

FIG. 2 is a sectional view showing a state where the stair unit 10 is installed in a corridor 60 on the first floor of a building. In the figure, the staircase unit 10 includes a first-floor partition panel 62.
And the side wall 16 is placed in surface contact with the machine room 2
The route of the duct piping and the like from the air conditioner main body 30 incorporated in the unit 0 is as follows.

The outside air intake port 34 is formed on the upper surface of the air conditioner main body 30, and the exhaust port 38 is formed on the lower surface of the air conditioner main body 30. An intake pipe 44 from the intake port 34
Alternatively, an exhaust pipe 48 is drawn from the exhaust port 38 and penetrates the floor 66 so as to take in or exhaust air under the floor.

From the air outlet 36, an air duct 46 is drawn, penetrates the floor 66, branches off under the floor in two directions, and is connected to an air duct 50 attached to the partition panel 62. The blower tube 46 is covered with a heat insulating material such as glass wool 46a under the floor, so that the blown air is kept warm.

The intake pipe 44, the exhaust pipe 48, and the blower pipe 46 are previously piped inside the stair unit 10 and slightly protrude from the bottom portion 18, while the floor 66 on which the stair unit 10 is installed is provided. At this point, a pipe (not shown) for connecting to each pipe is attached, and piping to be arranged under the floor is provided. By doing so, the work underneath the floor can be completed simply by installing the staircase unit 10 while fitting the respective pipes into the connecting tool, thereby simplifying the work.

It is to be noted that no duct piping is performed from the indoor air suction port 32, and the room air is directly sucked into the machine room 20 from the opening 24 of the stair unit 10 described above.

The ventilation duct 50 is covered by a rectangular-shaped duct cover 52. FIG. 3 is a perspective view showing the appearance of the duct cover 52. FIG. 4 shows 50.

In FIG. 3, the duct cover 52 is a side surface of one partition panel 62 and another partition panel 64 which is provided upright in a direction orthogonal to the partition panel.
Are attached to the side end surfaces of the
It is installed in the orthogonal part of. By installing in this position, the duct cover 52 is attached to the other partition panel 6.
4 can be provided, and the appearance can be improved. Further, the duct cover 52 has an outlet 54 at an upper portion and a lower portion, and a louver 54a is attached to the outlet 54 so that the intensity of the air can be adjusted. In the case of cooling, the upper outlet 5
By opening the opening 4 and opening the lower outlet at the time of heating, comfortable air adjustment can be performed.

Next, as shown in FIG. 4, the ventilation duct 50 inside the duct cover 52 has a vertical pipe 56 extending from the floor 66 to the ceiling 68, and two pipes at the upper part and the lower part of the vertical pipe 56, respectively. Branch pipe 5 that branches into two
The branch pipe 58 communicates with the outlet 54 of the duct cover 52 described above.

As described above, according to this embodiment,
Since the duct pipe passes through the floor portion 66 and passes from under the floor and is piped to the orthogonal portions of the partition panels 62 and 64, the duct pipe does not need to be provided above the ceiling. Therefore, even in a building having a structure in which the beam height is suppressed, the ceiling area is small, and the duct does not enter, air conditioning can be performed by the central air conditioning system.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention.
For example, in the above-described embodiment, the air conditioner main body 30 is installed below the uppermost floor of the stair portion 12, but the air conditioner main body 30 may be installed below the slope of the stair portion 12.

In the above-described embodiment, one blower tube 46 is provided.
Are branched in the middle of the pipe, but two air pipes, a cooling air pipe and a heating air pipe, may be piped. In this case, the cooling air blower is connected to the upper air outlet, and the heating air blower is connected to the lower air outlet, so that the cool air blows out from above and the warm air blows out from below. A comfortable room temperature can be achieved. In addition, in this configuration, since the outlets for the cool air and the warm air are different, the cool air is blown from above and the warm air is blown from below without switching the outlets.

Further, it is also possible to adopt a configuration in which a duct for sucking indoor air is drawn to the second floor to draw in dirty air on the second floor and discharge it to the outside of the room.

The duct cover may be attached to the side surface of the partition panel without integrating the duct cover with the partition panel, so as to have a columnar appearance.

Further, a part of the floor of the building is cut out so that the bottom of the stair unit can also be used as the floor of the building.
It is also possible to adopt a configuration in which a staircase unit is fitted into this cutout. In this case, by previously performing piping from the air conditioner main body to the lower surface of the bottom portion at the factory, work on site can be further reduced. Similarly, the side surface of the staircase unit may be configured to have a shape extending from the upper end of the staircase to the ceiling, and this side surface may be used as a wall panel of a building.

[0033]

As described above, according to the air conditioner storage stair unit according to the present invention, since the stairs are unitized, the stairs can be mass-produced at the factory and the stair construction work at the construction site can be omitted. This has the effect.
