BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to an attic air conditioner.

[0002]

2. Description of the Related Art Recently, in multi-story detached houses, an attic is often provided in addition to a living space on each floor, and accordingly, a demand for air conditioning of the attic is gradually increasing. On the other hand, for air conditioning of living spaces on the first and second floors,
Conventionally, air conditioners such as wall-mounted type, floor-standing type, and ceiling-embedded duct type have been used.

Therefore, it is possible to use the air conditioner used for air conditioning of the living space on the first and second floors to air-condition the attic.

FIG. 2 is an explanatory view showing a state in which each type of air conditioner used for ordinary air conditioning in the living space is installed in the attic R. In the figure, X is a wall-mounted air conditioner, which is installed on an installation plate P hanging from a ceiling surface C at a corner of the attic R. Y is a floor-standing air conditioner, which is installed on the floor surface F at the corner of the attic R. Z is a ceiling-embedded duct type air conditioner, which is installed in an installation space S provided outside the ceiling surface C, and the suction port of the suction duct Z _{1 and} the air outlet of the blowout duct Z ₂ are indoors from the ceiling surface C. It was made to face.

[0005]

[Problems to be Solved by the Invention] However, unlike the living spaces on the first and second floors, the attic often has a smaller ceiling area and a wall height that is not so high. It is generally considered desirable to install the wall-mounted air conditioner X in the upper part of the room in terms of air conditioning efficiency. Therefore, the wall-mounted air conditioner X has to be installed as shown in FIG. 2, and the space on the back side of the installation plate P becomes a dead space S ₁ and cannot be used. For even floor-type air conditioner Y, because it is a tall, it is difficult to place close to the wall surface of the attic R, the dead space S ₁ not available on the back side as shown in FIG. 2 It is easy to occur. Further, in the ceiling-embedded duct air conditioner Z, a large space is required to install the _two ducts Z ₁ and Z _{2 including} the suction duct Z ₁ and the blowout duct Z _2, and a large installation space S is required as a whole. Become.

When the conventional air conditioner used for the air conditioning of the living space on the first floor or the second floor is diverted to air-condition the attic R in this manner, a problem that a large installation space is required for the size of the room is required. However, due to this, there was a problem that an unusable dead space S ₁ was generated and it became difficult to perform comfortable air conditioning.

The present invention has been made in view of the above problems, and requires a small installation space and is capable of accommodating various inclination angles of the ceiling when installed on the ceiling of the attic. The purpose is to provide an air conditioner.

[0008]

Therefore, the attic air conditioner according to claim 1 is formed on one surface of the casing 3 and the air conditioner main body 2 in which the fan rotor 4, the heat exchanger 5 and the like are incorporated in the casing 3. An elastic duct 6 attached to the opening 31 is provided, and an air suction passage 65 that communicates an internal passage of the duct 6 with the suction side space 21 of the air conditioner body 2 is provided inside the elastic duct 6. It is characterized in that the partition wall 7 having elasticity is provided to partition the air outlet passage 66 communicating with the outlet side space 22 of the apparatus body 2.

The attic air conditioner according to claim 2 is
The stretchable duct 6 is characterized in that the vertical cross section is formed in a fan shape, and the casing 3 is rotatably connected to the ceiling grille 8 by a hinge 9 in the kaname part.

[0010]

In the air conditioner for the attic according to claim 1,
It can be installed by attaching the tip of the elastic duct 6 to the ceiling C of the attic, and making the respective openings of the air suction passage 65 and the air outlet passage 66 partitioned by the partition wall 7 face the interior of the attic. Therefore, as compared with the conventional ceiling-embedded duct type air conditioner having two ducts, the installation space can be reduced accordingly. If the duct 6 and the partition wall 7 are stretchable to transform the duct 6 into a fan shape, even if the ceiling C of the attic is inclined, the air conditioner main body 2 can be installed without being inclined.

In the attic air conditioner according to the second aspect of the present invention, the duct 6 can be easily deformed at the time of installation, so that the installation work corresponding to the inclined state of the ceiling C can be performed more easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete embodiment of the attic air conditioner of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing an installed state of an attic air conditioner according to an embodiment of the present invention.

The air conditioner 1 has an air-conditioner main body 2 in which necessary components such as a fan rotor 4 and a heat exchanger 5 are housed in a box-shaped casing 3 having one open surface, and an opening edge 31 formed on one surface of the casing 3. And an elastic duct 6 attached thereto.

The ventilation space inside the air conditioner main body 2 is divided into a suction side space 21 and a blowing side space 22, and a scroll curved surface 32 is formed on the inner surface of the casing 3 for appropriately guiding the wind flow. . Further, the casing 3 is provided with a drain drainage port 33, and a short pipe 34 connected to the drain drainage port 33 is inserted into a cover 35 attached to the roof.

The stretchable duct 6 is an adiabatic double-wall duct having an inner wall 61 and an outer wall 62 having a corrugated cross section (bellows) and a flexible heat insulating material 63 inserted between them, and the inner wall 61 and the outer wall It is possible to expand and contract by deforming the waveform of 62. Further, the duct 6 in the illustrated example has a fan-shaped vertical cross-sectional shape in a natural state in which the duct 6 is neither expanded nor contracted, and its upper end opening edge 64 is airtightly attached to the opening edge portion 31 of the casing 3. A partition wall 7 is provided inside the duct 6, and the partition wall 7 allows an internal passage of the duct 6 to communicate with the suction side space 21 and an air suction passage 65 that communicates with the blow side space 22. It is divided into and. The partition wall 7 is also a heat-insulating double wall in which a flexible heat insulating material 73 is loaded between the double walls 71 and 72 having a corrugated cross section, and is elastic by deforming the corrugations of the walls 71 and 72. is there.

The lower end opening edge 67 of the duct 6 is attached to the ceiling grill 8 attached to the ceiling C of the attic R. The ceiling grille 8 has a suction port 81 corresponding to the air suction passage 65 and an air outlet 8 corresponding to the air blowing passage 66.
2 are formed, and louvers 83 and 84 for adjusting the wind direction are provided on them. In addition, a hinge 9 is provided on the kaname part of the fan-shaped duct 6, and the casing 3 and the ceiling grill 8 are rotatably connected by the hinge 9, and the duct 6 is expanded and contracted in the direction of arrow A so that The inclination state of the air conditioner body 2 can be adjusted.

In the above structure, when the air conditioner body 2 is operated, the air in the attic R passes through the heat inlet 5 from the suction port 81, the air suction passage 65 and the suction side space 21, and further blows out. The room is conditioned by blowing out from the outlet 82 into the room of the attic R through the space 22 and the outlet passage 66. The air flow at this time is shown by arrows a, b, c, and d. Since the air intake passage 65 and the air outlet passage 66 of the duct 6 are insulated by the partition wall 7, heat transfer between the cold air and the warm air passing through them is unlikely to occur, and the air inlet passage 65 and the air outlet passage Since the passage 66 and the outside of the duct 6 are insulated by the duct 6,
The heat exchange between the cool air or the warm air passing through the passages 65 and 66 and the outside air does not easily occur. The drain water generated by the operation of the air conditioner body 2 is discharged from the drain drain port 33 through the pipe 34 onto the roof by a drain pump or the like (not shown).

In this air conditioner 1, the air conditioner body 2
The installation posture can be adjusted by expanding and contracting the duct 6 around the hinge 9. In other words,
It is possible to install the air conditioner main body 2 in the same proper posture even in a place where the inclination angle of the ceiling C is different. Further, with such a ceiling-mounted type, since it is not necessary to install the air conditioner 1 in the indoor space of the attic R, even if the air conditioner 1 is installed, the indoor space is narrowed and cannot be used in the indoor space. There is no room for dead space.

Although the duct 6 has a fan-shaped longitudinal section in this embodiment, the duct 6 does not have to have a fan-shaped natural shape. For example, even if the vertical section is rectangular, that is, the upper opening edge and the lower opening edge are parallel,
By contracting one side in the circumferential direction or expanding the other side, the sector can be deformed into a fan shape or a shape similar thereto, so that it is possible to cope with various inclination angles of the ceiling C. However, when it is desired to make the installation space of the air conditioner 1 as small as possible, it is desirable to make it fan-shaped as in the embodiment.

[0021]

As described above, since the air conditioner according to claim 1 can be installed in a narrow space above the ceiling of the attic, it is possible to efficiently perform air conditioning in the attic. At the same time, there will be no dead space that cannot be used with the installation of the air conditioner,
Moreover, there are many practical effects that the air conditioner body can be installed in a proper posture even if the ceiling is inclined.

In the attic air conditioner according to the second aspect, the duct can be easily deformed at the time of installation, and therefore the installation work corresponding to the tilted state of the ceiling C can be easily performed.
