CEILING-MOUNTED HEATING AND COOLING APPARATUS
A ceiling-mounted heating and cooling apparatus is disclosed, which is capable of uniformly heating and cooling an indoor space in such a manner that a discharge air from a heating and cooling apparatus is discharged toward a portion distanced far from an inlet. In a ceiling-mounted heating and cooling apparatus which is installed at a ceiling of a certain building and includes a suction port and a discharge port, there is provided an improved ceiling-mounted heating and cooling apparatus, comprising a duct part which is detachably installed at the discharge port and transfers a discharge air into the lower surfaces of the indoor of the building, wherein said duct part is a bellows or a telescope type unit. The indoor of the building can be uniformly heated or cooled by discharging discharge air further from the suction port of the ceiling-mounted heating and cooling apparatus.
1. Field of the Invention
The present invention relates to a ceiling-mounted heating and cooling apparatus (air conditioner), and in particular to a ceiling-mounted heating and cooling apparatus capable of uniformly heating and cooling an indoor space in such a manner that a discharge air from a heating and cooling apparatus is discharged toward a portion distanced far from an inlet.
2. Description of the Background Art
Generally, an air conditioner is referred to an air conditioning apparatus capable of achieving a temperature and moisture control and a purification wherein it is called an air purification apparatus, namely, a heating and cooling apparatus.
The heating and cooling apparatus is classified into a ceiling-mounted type in which it is installed on a ceiling, a stand type, namely, package type, a wall-mounted type in which it is installed on an inner wall, and a ceiling-embedded cassette type in which a part of the same is embedded into a wall and ceiling.
As shown therein, the ceiling-mounted cassette type heating and cooling apparatus 2 is installed on a ceiling 1 of a certain building. A suction port 3 is installed at a center portion of the heating and cooling apparatus 2 for sucking indoor air. A discharge port 4 is installed for discharging the air that is sucked from the suction port 3 and is cooled and heated.
In the thusly constituted heating and cooling apparatus 2, the distance between the suction port 3 and the discharge port 4 is too small, so that the air discharged from the discharge port 4 does not reach the bottom surface of the indoor space, but is sucked by the suction port 3.
In particular, since hot air is lighter than cold air, the hot air is not flown toward the lower region. There is a structural problem that the hot air stays for a certain time period in the space near the ceiling and is sucked by the suction port 3.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the present invention to overcome the above-described problems encountered in the conventional art.
It is another object of the present invention to provide a ceiling-mounted heating and cooling apparatus in which heated or cooled air reaches a portion distanced far from a suction port wherein the heated or cooled air is not directly sucked by the suction port.
It is further another object of the present invention to provide a ceiling-mounted heating and cooling apparatus capable of uniformly heating and cooling an indoor space in such a manner that a heated or cooled air discharged from a ceiling-mounted heating and cooling apparatus is far outputted.
To achieve the above objects, in a ceiling-mounted heating and cooling apparatus which is installed at a ceiling of a certain building and includes a suction port and a discharge port, there is provided an improved ceiling-mounted heating and cooling apparatus, comprising a duct part which is detachably installed at the discharge port and transfers a discharge air into the lower surfaces of the indoor of the building, wherein said duct part is a bellows or a telescope type unit.
The duct part includes a guide part which is designed to guide an extension of the same in a longitudinal direction.
The guide part includes a moving part for extending one end of the duct part, and a driving part which drives the moving part.
The moving part includes a belt which rotates so as to extend one end of the duct part, and driving and driven pulleys connected between the both ends of the duct part through the belt, and said driving part includes a driving motor which is connected with the driving pulley and is installed on the ceiling for thereby driving the driving pulley, and a switch which is electrically connected so as to normally rotate or reverse-rotate the driving motor.
The duct part further includes a fan installed at an end of the duct part for thereby efficiently discharging the discharge air.
The duct part is inclined downwards from the discharge part and gets distanced more and more from the suction port to the outer side.
BRIEF DESCRIPTION OF THE DRAWINGSThe present invention will become better understood with reference to the accompanying drawings which are given only by way of illustration and thus are not limitative of the present invention, wherein;
The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in
An extendable part 80 may be installed at the wall surface duct 60b positioned at a wall surface for thereby automatically extending the wall surface duct 60b. In the extendable part 80, one end of a rope 85 is provided at the motor 81 and a pulley 83 rotated by the motor 81 and is wound or loosened based on a normal or reverse rotation of the pulley 81. The other end of the rope 85 is installed at an end of the wall surface duct 60b, so that one end of the wall surface duct 60b is extendable in an up and down direction, and the motor 81 is controlled by an additional switch.
In the present invention, since the discharge air is uniformly distributed into the indoor space by automatically or manually extending the ducts, the discharged air is not directly sucked into the suction part, so that the indoor air can be widely and uniformly circulated for thereby achieving an uniform heating and cooling operation in the indoor space.
As described above, in the present invention, the duct capable of being extendable so that the discharge air from the suction port of the ceiling-mounted heating and cooling apparatus is installed at the discharge port, so that it is possible to uniformly heat or cool the inner space of the building.
In addition, in the present invention, it is possible to automatically extend the ducts.
As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
