 The present invention relates to an air conditioner suitable for heating two adjacent rooms such as a bathroom and a dressing room.

[0002]

[Prior Art]

 Hereinafter, a conventional two-room air conditioner will be described with reference to the drawings. In FIG. 2, a dressing room 100, which is a first air-conditioned space, and a bath room 200, which is a second air-conditioned space, are adjacent to each other with a wall 150 interposed therebetween. In the figure, holes 151 and 152 are formed above and below the wall 150, respectively, and the undressing room 100 and the bathroom 200 communicate with each other through both holes. The conventional air conditioner has an air passage 5 having an intake port 1 and an intake port 2 facing the dressing room 100 and the bathroom 200 on the hole 151 side, and a delivery path facing the dressing room 100 and the bathroom 200 on the hole 152 side, respectively. It has an air passage 6 having an air outlet 3 and an air outlet 4, and an air passage 7 connecting the air passage 5 and the air passage 6 to each other. The air passage 7 is provided with a fan 8. The fan 8 is connected to a rotating shaft of a motor 9 provided in a gap between the air passage 7 and the wall 150. When the fan 8 performs the ventilation operation by the rotation of the motor 9, the air in the dressing room 100 and the bathroom 200 is sucked from the intake port, ventilates the ventilation path 7, and is discharged from the air supply port. The ventilation passage 7 is also provided with a heater 10 so that the air ventilated through the ventilation passage 7 is heated. The air passage 5 is provided with an intake damper 11 which is a first damper. The intake damper 11 is movable by an angle α around the fulcrum 11a. On the other hand, the ventilation path 6 is provided with an air supply damper 12 which is a second damper. The air supply damper 12 is movable by an angle β around the fulcrum 12a. The heating modes for the undressing room 100, the bathroom 200, and both rooms are switched by setting the angles of the intake damper 11 and the air supply damper 12.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1a, b, and c are a side sectional view, a plan view, and an AA sectional view of a two-room air conditioner according to this embodiment, respectively. In the figure, the same or corresponding parts as those of the conventional example are designated by the same reference numerals. In FIG. 1, a dressing room 100 which is a first air-conditioned space and a bath room 200 which is a second air-conditioned space are adjacent to each other with a wall 150 interposed therebetween. In the figure, a hole 151 is formed in the wall 150 so that the dressing room 100 and the bathroom 200 communicate with each other. The air conditioner according to the present embodiment has an intake port 1 and an air supply port 3 that are open to the undressing room 100 side, and an intake port 2 and an air supply port 4 that project from the hole 151 of the wall 150 and open to the bathroom 200 side. .. The intake port 2 is formed on the outer periphery of the air supply port 4. The intake port 1 and the intake port 2 are connected by a ventilation path 5. The air supply port 3 and the air supply port 4 are connected by a ventilation path 6. The air passage 5 and the air passage 6 are communicated with each other by the air passage 7. The air passage 5 is formed in the space between the air passage 7 and the wall 150 except for the motor 9 and its vicinity described later. The air passage 7 is provided with a fan 8. The fan 8 is connected to a rotating shaft of a motor 9 provided in a gap between the air passage 7 and the wall 150. When the fan 8 performs the air-flow operation by the rotation of the motor 9, the air in the dressing room 100 and the bathroom 200 is sucked from the intake port, ventilated through the ventilation path 7, and sent out from the air supply port. The ventilation passage 7 is also provided with a heater 10 so that the air ventilated through the ventilation passage 7 is heated. The air passage 6 is provided with an air supply damper 12 which is a first damper. The air supply damper 12 rotates about a fulcrum 12a as a central axis. On the other hand, the ventilation path 5 is provided with an intake damper 11 which is a second damper. The intake damper 11 rotates about the fulcrum 11a as the center axis. In this embodiment, the heating mode for the undressing room 100, the bathroom 200, and both rooms (two rooms) can be switched by setting the angles of the intake damper 11 and the air supply damper 12.

Next, the operation of the present device will be described with reference to FIG. When the power source (not shown) of the device is turned on, the heater 10 starts to generate heat. On the other hand, the motor 9 rotates and the fan 8 starts flowing air. FIG. 1 shows a two-room heating mode. In this mode, the intake damper 11 and the air supply damper 12 are set to the neutral position. Air from the undressing room 100 and the bathroom 200 is sucked from the intake ports 1 and 2, respectively, and ventilates through the ventilation passage 5, and is introduced into the ventilation passage 7 by the intake damper 11. The air introduced into the ventilation passage 7 is heated by the heater 10. The heated air is distributed by the air supply damper 12 and is ventilated through the air passage 6 to be supplied from the air supply port 3 and the air supply port 4 to the dressing room 100 and the bathroom 200, respectively. As a result, air circulation occurs in the undressing room 100 and the bathroom 200 as indicated by arrows 101 and 102. After that, heating is performed until the room temperature of both rooms rises to a desired temperature. By adjusting the set angles of the intake damper 11 and the air supply damper 12, the heating ratio between the dressing room 100 and the bathroom 200 can be adjusted arbitrarily. Next, in the dressing room heating mode, the intake damper 11 is set to the left side (shown by a chain double-dashed line) in the figure, and the air supply damper is set to a horizontal state (shown by a chain double-dashed line) in the figure. As a result, only the air in the dressing room 100 is taken in through the intake port 1 and heated in the same manner as in the two-chamber heating mode, and is delivered to the dressing room 100 only through the air supply port 3. In the dressing room 100, air is circulated as shown by an arrow 101, and heating is performed until the room temperature rises to a desired temperature. Next, in the bathroom heating mode, the intake damper 11 is set to the right side (shown by a chain double-dashed line) in the figure, and the air supply damper 12 is set to be upright (shown by a chain double-dashed line) in the figure. As a result, only the air in the bathroom 200 is taken in from the intake port 2, heated in the same manner as in the two-room heating mode, and sent out to the bathroom 200 only from the air supply port 4. Air is circulated in the bathroom 200 as shown by an arrow 201, and heating is performed until the room temperature rises to a desired temperature. As described above, in this device, intake and air can be supplied only to the room to be heated by setting the intake damper and the air supply damper. The intake damper 11 and the air supply damper 12 can be set mechanically or electromagnetically. Further, by linking the operations of both dampers, the ratio of intake air and air supply may be set only by selecting a desired room to be heated.

As described above, in this device, since the intake port 2 is formed around the air supply port 4, only one hole needs to be provided in the wall 150. The intake port is not limited to the concentric outer circumference of the air supply port, but may be provided adjacently. Further, in this embodiment, the ventilation passage 5 is provided by utilizing the gap between the fan 8 and the wall 150, and the thickness with respect to the wall is made the same as that of the conventional example, but the arrangement state of the ventilation passage is not limited to this. is not.

[0009]

[Effect of the device]

 In the two-room air conditioner according to the present invention, since the intake port is formed around the air supply port, it suffices to provide one hole in the wall where the installation is performed, and the installation work can be simplified.
