Description
- This application claims the benefit of Korean Patent Application No. 10-2005-0077437, filed on Aug. 23, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

- 2. Description of the Related Art
- A conventional independent temperature controlled refrigerator, as disclosed in Korean Patent No. 10-234066, includes an evaporator for refrigerating a refrigerator compartment and an evaporator for refrigerating a freezer compartment. This enables easy control of temperatures of the freezer compartment and the refrigerator compartment using the evaporators.
- When the evaporators are installed in the conventional refrigerator, the evaporator for the freezer compartment is installed at a rear side of the freezer compartment and the evaporator for the refrigerator compartment is installed at a rear side of the refrigerator compartment, and, afterwards, refrigerating pipes are connected to the respective evaporators. The pipes are connected to an inlet and an outlet of the evaporator for the freezer compartment at an inner rear side of the freezer compartment by welding and to an inlet and an outlet of the evaporator for the refrigerator compartment at an inner rear side of the refrigerator compartment by welding.
- However, in the conventional refrigerator, since the evaporators must be independently installed in the freezer compartment and the refrigerator compartment during manufacture, the installation of the evaporators is troublesome and complicated. Particularly, since, when installing the evaporators, a worker must connect the pipes to the freezer compartment and, afterwards, must connect the pipes to the refrigerator compartment, the installation of the evaporators is difficult.
- Moreover, in the conventional refrigerator, the pipes of the evaporator for the refrigerator compartment and the evaporator for the freezer compartment are connected in series so that refrigerant, passed through one of the evaporators, flows to the other of the evaporators. Additionally, defrosting heaters for defrosting the evaporators are installed in the lower sides of the evaporators.
- However, in the conventional refrigerator, hot refrigerant in the lower evaporator flows toward the upper evaporator due to thermosyphoning when the evaporator positioned in the lower side thereof is defrosted, is defrosted thereby heating the upper evaporator. Due to this phenomenon, the upper evaporator is unnecessarily heated and heating of the lower evaporator is delayed thereby elongating heating time.
- Accordingly, it is an aspect of the present invention to provide a refrigerator in which evaporators refrigerating a plurality of compartments are integrally formed so that the evaporators are easily installed.
- Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the invention.
- It is another aspect of the invention to provide a refrigerator in which pipes are easily connected to evaporators.
- It is still another aspect of the invention to provide a refrigerator in which, when defrosting is performed in one of evaporators of compartments, heat transfer from one evaporator to the other evaporator is minimized such that defrosting time is reduced and energy is conserved.
- These and/or other aspects of the present invention provides a refrigerator including a main body including a first compartment disposed at an upper side thereof and a second compartment disposed at a lower side thereof, and an evaporator including a first refrigerating part to refrigerate the first compartment integrally connected with a second refrigerating part to refrigerate the second compartment via a connection pipe, wherein the connection pipe connects an upper side of the first refrigerating part with the second refrigerating part.
- The connection pipe is connected with the upper side of the second refrigerating part.
- The first refrigerating part, the second refrigerating part and the connection pipe form a single pipe.
- The first refrigerating part of the evaporator is spaced apart from the second refrigerating part of the evaporator.
- The evaporator includes a housing to accommodate and support the first refrigerating part and the second refrigerating part, and a defrost water tray to partition an inside of the housing between the first refrigerating part and the second refrigerating part and to discharge defrost water flowed down from the first refrigerating part.
- The evaporator further includes a first defrosting heater installed to a lower side of the first refrigerating part, and a second defrosting heater installed to a lower side of the second refrigerating part.
- It is another aspect of the present invention to provide a refrigerator including a main body including a first compartment and a second compartment separated from the first compartment, and an evaporator including a first refrigerating part installed in the first compartment integrally formed with a second refrigerating part installed in the second compartment, wherein an inlet pipe and an outlet pipe of the evaporator are disposed to one of the first refrigerating part and the second refrigerating part.
- It is yet another aspect of the present invention to provide a refrigerator including a main body including a first compartment disposed at an upper side thereof and a second compartment disposed at a lower side thereof and separated from the first compartment, and an evaporator including a first refrigerating part installed in the first compartment and a second compartment installed in the second compartment integrally connected with each other by a connection pipe, wherein an inlet pipe and an outlet pipe of the evaporator are disposed to one of the first refrigerating part and the second refrigerating part, and the connection pipe extends from a lower side of the second refrigerating part and is connected with an upper side of the first refrigerating part.

evaporator 20 comprises a first defrostingheater 41 installed in a lower side of the first refrigeratingpart 21 and a seconddefrosting heater 42 installed in a lower side of the second refrigeratingpart 22 such that the firstdefrosting heater 41 heats the first refrigeratingpart 21 to remove frost on the first refrigeratingpart 21, and the seconddefrosting heater 42 heats the second refrigeratingpart 22 to remove frost on the second refrigeratingpart 22. - Moreover, the
evaporator 20 comprises adefrost water tray 27 installed in thehousing 24 to partition an inside of thehousing 24 between the first refrigeratingpart 21 and the second refrigeratingpart 22, and to discharge defrost water flowed down from the first refrigeratingpart 21. The defrost water tray 27, as shown inFIG. 1 , partitions the space between thefirst compartment 11 and thesecond compartment 12 when theevaporator 20 is installed in themain body 10 so as to block air flow between thefirst compartment 11 and thesecond compartment 12. -
FIG. 3 illustrates pipe arrangement of theevaporator 20 of the refrigerator shown inFIG. 1 . InFIG. 3 , the first refrigeratingpart 21 comprises a right-sidedfirst circulation part 21 a and a left-sidedsecond circulation part 21 b, lower sides of which are connected with each other, and the second refrigeratingpart 22 comprises a left-sidedfirst circulation part 22 a and a right-sidedsecond circulation part 22 b, lower sides of which are connected with each other. Ends of aconnection pipe 23 are connected with an upper side of thefirst circulation part 21 a of the first refrigeratingpart 21 and an upper side of thesecond circulation part 22 b of the second refrigeratingpart 22, respectively. An inlet pipe 28 (also shown inFIG. 2 ) extends from the upper side of the first refrigeratingpart 21 to the second refrigeratingpart 22 and is connected with the upper side of thefirst circulation part 22 a. Anoutlet pipe 29 is connected with the upper side of thesecond circulation part 21 b of the first refrigeratingpart 21. By doing so, refrigerant introduced through theinlet pipe 28 sequentially passes through thefirst circulation part 22 a of the second refrigeratingpart 22, thesecond circulation part 22 b of the second refrigeratingpart 22, theconnection pipe 23, thefirst circulation part 21 a of the first refrigeratingpart 21, and thesecond circulation part 21 b of the first refrigeratingpart 21, and then flows through theoutlet pipe 29. - When manufacturing the
evaporator 20, a single long pipe is bent without seams as shown inFIG. 3 and coolingfins first circulation parts second circulation parts parts first circulation part 21 a of the first refrigeratingpart 21 is overlapped with thesecond circulation part 21 b of the first refrigeratingpart 21 and thesecond circulation part 22 b of the second refrigeratingpart 22 is overlapped with thefirst circulation part 22 a of the second refrigeratingpart 22. By doing so, theevaporator 20 is formed as shown inFIG. 2 . - The
evaporator 20 is installed in themain body 10, as shown inFIG. 1 , such that the first refrigeratingpart 21 is disposed at the rear side of thefirst compartment 11 and the second refrigeratingpart 22 is disposed at the rear side of thesecond compartment 12, and thesecond duct 34 is coupled with thethird duct 36 so as to cover theevaporator 20. Theintermediate partition 13 for partitioning the space between thefirst compartment 11 and thesecond compartment 12 is separated from themain body 10 and is coupled with themain body 10 after installation of theevaporator 20 and the second andthird ducts intermediate partition 13 is separated so that theevaporator 20 is easily installed. Although theevaporator 20 is firstly installed and the second andthird ducts evaporator 20 may be installed in themain body 10 after being coupled with the second andthird ducts - After the installation of the
evaporator 20 in themain body 10, theinlet pipe 28 and theoutlet pipe 29 of theevaporator 20 are connected withpipes 43. Since theinlet pipe 28 and theoutlet pipe 29 of theevaporator 20 of the present invention, as shown inFIG. 3 , are positioned at the upper side of the first refrigeratingpart 21, thepipes 43 are easily connected. Since the connection of the pipes (i.e., theinlet pipe 28 and theoutlet pipe 29 to respective pipes 43) is performed only in the space of thefirst compartment 11 when connecting thepipes 43, theevaporator 20 is easily installed and time for the connection of the pipes is also reduced. Thepipes 43 are connected by a weldingprocess using connectors 44. -
FIG. 4 shows the arrangement of theinlet pipe 28 and theoutlet pie 29 according to another preferred embodiment of the present invention. Differing fromFIG. 3 , aninlet pipe 51 is disposed to the second refrigeratingpart 22 and anoutlet pipe 52 is extended from the first refrigeratingpart 21 to the second refrigeratingpart 22. This arrangement is an alternative, whereby the connection of the pipes is performed in a space of the second refrigeratingpart 12. - Moreover, since the
evaporator 20, as shown inFIG. 3 , is installed such that the upper end of theconnection pipe 23 is connected with the upper side of thefirst circulation part 21 a of the first refrigeratingpart 21 and the lower end of theconnection pipe 23 is connected to the upper side of thesecond circulation part 22 b of the second refrigeratingpart 22, heat transfer from the second refrigeratingpart 22 to the first refrigeratingpart 21 is minimized when defrosting is performed so that defrosting is rapidly carried out. - The upper end of the
connection pipe 23 is connected with the upper side of the first refrigeratingpart 21 such that hot refrigerant of the second refrigeratingpart 22 is prevented from flowing toward the first refrigeratingpart 21 due to thermosyphoning. That is, when defrosting the second refrigeratingpart 22, refrigerant in the first refrigeratingpart 21 remains in the condensed state and does not flow toward the lower second refrigeratingpart 22. - Therefore, when defrosting the second refrigerating
part 22, the second refrigeratingpart 22 is rapidly heated such that the defrosting time can be reduced and the problem that temperature of the compartment is unnecessarily raised due to the reduction of the defrosting time during the defrosting is minimized. Therefore, energy loss can be reduced. Since, when defrosting the first refrigeratingpart 21, the hot refrigerant in the first refrigeratingpart 21 cannot flow toward the lower second refrigeratingpart 22, heat transfer between the first and second refrigerating parts does not occur. - As described above, since the refrigerator of the present invention includes an evaporator in which the first refrigerating part for refrigerating the first compartment and the second refrigerating part for refrigerating the second compartment are integrally connected with each other, the evaporator can be completely installed in the refrigerator by installing a single evaporator set in the refrigerator when manufacturing the refrigerator. Particularly, the connection of the pipes for the installation of the evaporator can be minimized so that the evaporator can be rapidly and easily installed.
- Moreover, according to the refrigerator of the present invention, since the inlet pipe and the outlet pipe of the evaporator are disposed to one of the first refrigerating part and the second refrigerating part, the connection of the pipes is performed in only one of the compartments so that the pipes are easily connected.
- Additionally, since the connection pipe for connecting the upper first refrigerating part to the lower second refrigerating part extends from the second refrigerating part to the upper side of the first refrigerating part, heat transfer between the first refrigerating part and the second refrigerating part is prevented. Thus, when defrosting the second refrigerating part, the second refrigerating part is rapidly heated to reduce the defrosting time, and due to the reduction of the defrosting time, the problem that temperature of the compartments is raised during the defrosting is minimized and energy loss can be reduced.
- Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
