[Problems to be Solved by the Invention] However, in the conventional system, when the fan of the fan coil unit is stopped, a short circuit tends to occur between the outside air supply position and the exhaust port, resulting in insufficient ventilation in the cabin. In addition, energy is wasted in the cooling or heating load caused by solar radiation in a perimeter zone such as near a window or the difference between the outside temperature and the indoor temperature. Furthermore, in winter, there is a problem in that cold drafts occur in perimeter zones such as near windows.

The present invention solves the above problems, and provides an exhaust switching system and switching system for hotel rooms that can prevent short circuits in ventilation, reduce heating and cooling loads, and prevent the occurrence of cold drafts. The purpose is to provide equipment.

[0005]

[Means for Solving the Problems] To this end, the exhaust gas switching system for a hotel guest room of the present invention includes a fan coil unit 9 disposed in a guest room 1 to supply outside air and to cool or heat indoor air; The unit bath 2 includes an exhaust port 13 formed in the ceiling, a curtain box 20 disposed above the window 5, and an inlet 21 formed in the curtain box 20. It is characterized in that one or both of the air from the air can be selectively exhausted.

The exhaust switching device for a hotel guest room of the present invention also includes a fan coil unit 9 disposed in the guest room 1 to supply outside air and to cool or heat the indoor air, and a fan coil unit 9 arranged in the ceiling of the unit bath 2. an exhaust port 13 formed in;
A curtain box 20 disposed above the window 5, an inlet 21 formed in the curtain box 20, and an exhaust outlet 1
3, an exhaust switching device 15 disposed between the suction port 21 and the exhaust manifold 16, and a switching damper 29 rotatably provided within the exhaust switching device 15.
9 allows one or both of the air from the exhaust port 13 and the suction port 21 to be selectively connected to the exhaust manifold pipe 16.

[0007] The numbers added to the above structures are for comparison with the drawings to facilitate understanding, and are not intended to limit the structure of the present invention in any way.

[0008]

[Operation] In the present invention, for example, as shown in the figure, if there is a cooling or heating load caused by sunlight hitting the window 5 or a difference between the outside temperature and the indoor temperature, before check-in,
The switching damper 29 of the exhaust switching device 15 is rotated to the position shown in Y in FIG. 4, and the air between the window 5 and the curtain 6 is discharged through the suction port 21, the duct 19, and the exhaust manifold pipe 16, thereby cooling the air. Alternatively, the heating load may be reduced, and the switching damper 29 of the exhaust switching device 15 may be
is rotated to the position shown in Z in Fig. 4, and indoor air is exhausted from both the exhaust port 13 of the unit bath 2 and the suction port 21 of the curtain box 20, thereby preventing cold drafts in perimeter zones such as near windows. Prevent occurrence.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. 1, 2, and 3 show one embodiment of the exhaust switching system for hotel guest rooms according to the present invention, in which FIG. 1 is a plan view, FIG. 2 is a sectional view, and FIG. 3 is a sectional view taken along line A-A in FIG. 2. It is a diagram.

1 is a guest room, 2 is a unit bath, 3 is a hallway,
Reference numeral 5 indicates a window, and reference numeral 6 indicates a curtain. A fan coil unit 9 is disposed on the ceiling near the entrance 7 of the guest room 1 to circulate indoor air and cool or heat the air. The fan coil unit 9 is supplied with outside air from outside through an outside air supply pipe 10, and is configured to suck indoor air through an inlet 11 and blow out air for heating and cooling through an outlet 12.

[0011] There is an exhaust port 13 in the ceiling of the unit bath 2.
is formed and connected to an exhaust manifold pipe 16 via an exhaust switching device 15. In addition, the exhaust switching device 15
It is also connected to a duct 19 disposed in the curtain box 20, and the duct 19 is connected to a curtain box 20. A suction port 21 is formed in the curtain box 20 so that air between the window 5 and the curtain 6 can be sucked in.

FIGS. 4 and 5 show one embodiment of the exhaust switching device 15 according to the present invention, with FIG. 4 being a sectional view and FIG. 5 being a front view. The exhaust switching device 15 includes a casing 26 having an exhaust port 22 and two intake ports 23 and 25, and a switching damper 29 rotatably provided in the casing 26 by a rotating shaft 27. The suction port 23 is connected to the exhaust port 13 of the unit bath 2, and the suction port 25 is connected to the suction port 21 of the curtain box 20 via the duct 19.

[0013] The operation of the exhaust gas switching system for hotel guest rooms of the present invention having the above configuration will be explained. When the passenger compartment 1 is occupied, the fan coil unit 9 is operated, and the switching damper 29 of the exhaust switching device 15 is set to the position shown in X in FIG. Exhaust is primarily ventilated through the exhaust port 13 and the exhaust manifold 16. If there is a cooling or heating load caused by sunlight hitting the window 5 or a difference between the outside temperature and the indoor temperature, before check-in, rotate the switching damper 29 of the exhaust switching device 15 to the position shown in Y in FIG. window 5
The air between the curtain 6 and the suction port 21, the duct 19,
The cooling or heating load is reduced by discharging the air through the exhaust manifold pipe 16. In addition, at late night in winter, etc., the switching damper 29 of the exhaust switching device 15 is rotated to the position shown in Z in FIG.
