Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to an air conditioner, and more particularly, to a personal or particular space air conditioner, which can be installed at a desired located and fashion enough to permit air conditioning, not for an entire air conditioning space, but for a particular space.




2. Background of the Related Art




The air conditioner maintains a temperature, a humidity, and the like of a desired space (air conditioned space) at appropriate states by using a refrigerating cycle of compression, condensation, expansion, and evaporation of a refrigerant. In the air conditioner, there are package type air conditioners and room air conditioners. In general, the air conditioner has a heat discharging part with the condenser and a heat absorbing part with the evaporator arranged in separate places. And, since the heat discharging part is arranged outside of the room, the heat discharging part is called as an outdoor unit, and, since the heat absorbing part is arranged inside the room, the heat absorbing part is called as an indoor unit. A related art room air conditioner will be explained with reference to FIG.


1


.




A heat discharging part


5


is arranged outside of the room, and the heat absorbing part


3


is arranged inside of the room. For an example, the heat absorbing part


3


is fixed to a wall, and the heat discharging part


5


is placed on a veranda or the like. There is refrigerant pipe lines connected between the heat absorbing part


3


and the heat discharging part


5


for flow of the refrigerant. And, there is a drain hose


9


connected to the heat absorbing part


3


for discharging the condensate formed at the evaporator of the heat absorbing part


3


.




A system of the heat absorbing part will be explained, with reference to FIG.


2


. The heat absorbing part


3


is provided with an evaporator


37


and a fan


38


fitted inside thereof. And, there is a suction grill


33


in front portion of a body


31


of the heat absorbing part, for drawing air from the room, and a discharge grill


35


below the body


31


of the heat absorbing part, for discharging cooled air heat exchanged with the evaporator


37


into the room again.




The operation of the related art air conditioner will be explained, with reference to

FIGS. 1 and 2

.




The room air flowed into the suction grill


33


is cooled down as the room air is heat exchanged at the evaporator


37


, and discharged into the room again, for maintaining the room temperature at a preset level. The evaporated refrigerant is provided to a compressor in the heat discharging part


5


through a low pressure pipe line


7




b,


and compressed and provided to the condenser. The refrigerant makes heat exchange with external air at the condenser to condense the refrigerant and discharge heated air outside of the room. The condensed refrigerant is expanded at an expansion valve and flows to the evaporator


37


through a high pressure pipe line


7




a


again. By repeating the foregoing process, the room, i.e., the air conditioned space


1


can be maintained at a desired temperature.




In the meantime, water drops are formed on a surface of the evaporator


37


during heat exchange between the room air and the refrigerant at the evaporator


37


in the heat absorbing part


3


, because a surface temperature of the evaporator


37


is very low compared to the room temperature, to cool down the room air in contact with the evaporator


37


below a dew point of the air. The water drops formed at the evaporator


37


are collected at a place along a drain channel


39


in the heat absorbing part


3


, and drained to outside of the room through a drain hose


9


.




However, the related art air conditioner has the following problems.




First, the related art air conditioner in general is bulky and heavy such that installation of the air conditioner is not convenient. And, moving once installed indoor unit or outdoor unit to another place is difficult, since the refrigerant pipe lines are formed of copper tubes, and passed through a wall for fastening at desired locations.




Second, the transfer of cooled air from the heat absorbing part to a distant place from the heat absorbing part takes much time period, to require a long time period in cooling down the distant place. And, an intensive local air conditioning for a particular space, not the entire air conditioning space, has not been possible. If moving the air conditioner to a space where air conditioning is required is possible, the intensive air conditioning for the particular space can be made available, that is in fact not possible by using the related art air conditioner.




Third, even though the discharge grill in the heat discharging part has means for regulating a blow direction, the blow direction regulation has a limitation since the heat absorbing part itself is fixed to wall or the like.




Therefore, development of a particular space cooling, or personal(small sized) air conditioner is required, which is convenient and simple in installation and movement, enough to permit an instant cooling of, not the entire air conditioning space, but a particular space.




SUMMARY OF THE INVENTION




Accordingly, the present invention is directed to a personal air conditioner that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.




An object of the present invention is to provide a personal air conditioner which can be installed and moved with easy to permit an effective air conditioning of a particular space.




Another object of the present invention is to provide a personal air conditioner, of which direction of cooled air discharge from a heat absorbing part can be regulated, freely.




Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.




To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, the personal air conditioner includes a heat discharging part having small sized compressor and condenser, a heat absorbing part having a small sized evaporator, a flexible high pressure pipe line connecting between the condenser and the evaporator, and a flexible low pressure pipe line connecting between the evaporator and the compressor, thereby installation and moving of the heat discharging part and the heat absorbing part are convenient. The high pressure pipe line and the low pressure pipe line are preferably detachable. Thus, since coupling and separation of the heat discharging part and the heat absorbing part are possible, fast cooling down of a desired space is possible.




The personal air conditioner further includes heat absorbing part fixing means having one end connected to the heat absorbing part and the other end supported on a desired location.




The heat absorbing part fixing means includes a base movable and supported on a desired location, a first supporting member fixed on the base, and a second supporting member having one end height adjustably coupled to the first supporting member and the other end rotatably coupled to the heat absorbing part. And, the personal air conditioner further includes angle adjusting means in a lower portion of the second supporting member for adjusting an angle in up and down direction.




Thus, the personal air conditioner of the present invention can cool down a desired space within a short time period because installation and movement of the heat discharging part and the heat absorbing part are convenient, and cooled air from the heat absorbing part can be directed as desired.




It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

. Alike the related art air conditioner, the air conditioner of the present invention also includes a compressor, a condenser, an expansion valve, an evaporator and the like, for employing the refrigerating cycle. Of course, the condenser is in the heat discharging part


100


, and the evaporator is in the heat absorbing part


200


. And, though it is desirable that the compressor and the expansion valve are provided to the heat discharging part, the compressor and the expansion valve may be provided to the heat absorbing part. And, the heat discharging part


100


and the heat absorbing part


200


have fans respectively, for enhancing a heat exchange efficiency. However, since a purpose of the air conditioner of the present invention lies on cooling a local space, an air conditioner with a small cooling capacity is acceptable, with consequential small sized components in the personal air conditioner, such as compressors and the like, along with the heat absorbing part


200


and heat discharging part


100


, that renders a convenience in moving and installation of the air conditioner. Moreover, it is preferable that the high pressure pipe line


310


and the low pressure pipe line


320


are formed of flexible material for improving the convenience in moving and installation of the air conditioner, and detachably connected between the heat absorbing part


200


and the heat discharging part


100


by means of quick coupling or the like, for easy installation and moving of the heat absorbing part


200


and the heat discharging part


100


, when it is required to take an appropriate measure for refilling the refrigerant. On the other hand, in general, one end of the drain hose


330


is connected to the heat absorbing part


200


, and the other end is exposed to outside of the room for discharging the condensate outside of the room. However, it is preferable for the personal air conditioner of the present invention that the other end of the drain hose


330


is connected to the heat discharging part


100


, because, as the heat discharging part


100


is in general installed outside of the room, it is convenient in view of installation that the condensate is transferred to the heat discharging part


100


and discharge the condensate to outside of the room therefrom. It is of course preferable that the drain hose


330


is also formed of a flexible material.




A configuration of installation of the air conditioner of the present invention will be explained, with reference to

FIGS. 4 and 5

. Because the related art air conditioner is bulky, it has been difficult for the user to install the air conditioner for himself, actually. However, the air conditioner of the present invention has small and light heat discharging part


100


and heat absorbing part


200


and flexible pipe lines, installation of which is easy, the user can install it at a desired location with easy.

, the heat discharging part


100


may be installed, for an example, on a veranda or fixed to an outer side of a wall, and the heat absorbing part


200


may be placed on a desired location in a room, for an example, on a computer monitor


40


. Of course, since the heat absorbing part


200


and the heat discharging part


100


is movable, the location is not limited to this, but the heat absorbing part


100


can be placed on a TV receive.r or a desk, or the like. As shown in

FIG. 5

, it is possible to fix the heat absorbing part


200


to a heat absorbing part fixing means


400


for easy placing of the heat absorbing part


200


at a desired place. And, though a hole is required to be made in a wall for the refrigerant pipe lines connecting the heat absorbing part


200


and the heat discharging part


100


in the related art air conditioner, the air conditioner of the present invention permits connection of the pipe lines through a window as the pipe lines are small and flexible. Other than the foregoing method for installing the heat absorbing part


200


, various methods are available. For an example, the heat absorbing part


200


may be mounted on a wall, or installed by other different methods to a desired location.




In the meantime, since the heat discharging part


100


of the present invention is small, a plurality of the heat discharging parts


100


may be installed. And, both the heat absorbing part


200


and the heat discharging part


100


may be installed in a room, when an outlet of the heat absorbing part


200


is required to be directed to a direction cooling is required, and the heat discharging part


100


is directed to the other side. Of course, it is preferable that an appropriate measure is taken to direct a heat from the heat discharging part


100


to outside of the room.




In the meantime, it is preferable that the heat absorbing part


200


is fixed to a heat absorbing part fixing means for easy installation of the heat absorbing part


200


at a desired location as a simple placement of the heat absorbing part fixing means fulfils the installation of the heat absorbing part


200


. An embodiment of installation of the heat absorbing part of the air conditioner of the present invention will be explained, with reference to FIG.

. Therefore, according to this embodiment, an easy installation of the heat absorbing part


200


at a desired location is possible by placing the base


410


of the heat absorbing part


200


at the desired location. In this instance, the user may adjust height and angle of the heat absorbing part


200


in directing cooled air to a desired space for an effective cooling within a short time period. Other than the foregoing method, the heat absorbing part

432


via one pin


436


and the other end rotatably connected to the heat absorbing part


200


via the other pin


438


. However, different from the first embodiment, the base


430


is fixed to a wall. Consequently, an installation height of the heat absorbing part


200


can not be adjusted. Therefore, it is preferable that the pin


436

432


and the second supporting part


434


and the pin


438


connecting the second supporting part


434


and the heat absorbing part


200
