Description
TECHNICAL FIELD
[0001] The present invention relates to a refrigerator, and more
particularly, to a refrigerator having a condenser at an outer side
of a machine room in which a compressor is installed.
BACKGROUND ART
[0002] Generally, a refrigerator serves to store food and drink in
a low temperature state by providing a cooling chamber. The cooling
chamber of the refrigerator may be divided into a freezing chamber
maintained in a temperature below zero, and a refrigerating chamber
maintained in a temperature above zero.
[0003] The refrigerator can freshly store food in a frozen state or
in a cooled state by lowering each temperature of the freezing
chamber and the refrigerating chamber, by transmitting cool air to
the freezing chamber and the refrigerating chamber. Here, the cool
air is generated by a refrigeration cycle constituted by a
compressor, a condenser, an expansion valve, and an evaporator.
[0004] For installation of the refrigeration cycle, a machine room
is installed in a rear bottom portion of the refrigerator. A fan, a
compressor, a condenser, and so on constituting the refrigeration
cycle are installed at the machine room.
[0005] A great deal of heat occurs from the compressor, the
condenser, and so on of the machine room, and the occurred heat has
to be dissipated outside. For dissipation of heat, a plurality of
vents through which external air flows are formed at a cover for
protecting the machine room. And, a blowing fan is installed at the
machine room so as to generate a blowing force such that external
air can be introduced into the vents.
[0006] However, since the conventional machine room is equipped
therein with not only the condenser but also the compressor, the
fan, etc., the machine room occupies a prescribed space of a bottom
portion of the refrigerator.
[0007] The space occupied by the machine room can not be utilized
as a storage space of the refrigerator. Accordingly, there has been
proposed a refrigerator having a structure in which heat of the
condenser is smoothly emitted, and the machine room is
compacted.
DISCLOSURE OF THE INVENTION
[0008] Therefore, it is an object of the present invention to
provide a refrigerator capable of sufficiently emitting heat of a
machine room and a condenser, and implementing a compact
configuration of the machine room.
[0009] To achieve these and other advantages and in accordance with
the purpose of the present invention, as embodied and broadly
described herein, there is provided a refrigerator, comprising: a
case having a cooling chamber; a machine room disposed on one side
of the case, and configured to accommodate a compressor therein; a
condenser disposed on an outer surface of the case; and a heat
emission unit configured to guide external air of the case for heat
emission of the compressor and the condenser.
[0010] In the refrigerator, the machine room may be disposed on a
rear bottom portion of the case, and the condenser may be disposed
on a rear surface of the case.
[0011] The heat emission unit may include a machine room cover
configured to cover the machine room, and having a plurality of
first vents; a condenser case configured to fix the condenser
accommodated therein onto a wall surface of the case, having a
plurality of second vents, and communicated with one side of the
machine room; a blowing fan configured to generate a flow of air
passing through the first and second vents; and a communication
portion configured to communicate an inner side of the machine room
with an inner side of the condenser case.
[0012] The blowing fan may be installed such that air introduced
into one of the first vents and the second vents is discharged to
the other.
[0013] The fan may be coupled to a rear surface of the machine room
cover.
[0014] The fan may be installed at the communication portion
configured to communicate an inner side of the machine room with an
inner side of the condenser case.
[0015] The blowing fan may be implemented as a cross flow fan.
[0016] The communication portion may include a communication duct
configured to communicate an inner side of the machine room with a
rear side of the case, and a guide duct configured to communicate
an inner side of the communication duct with an inner side of the
condenser case.
[0017] The communication duct may be formed at a lower middle
portion on a rear surface of the case.
[0018] The machine room may have an opened surface toward a side
surface of the case, and the machine room cover may cover the
opened surface. The communication duct may be formed on a rear
surface of the case so as to be adjacent to the opened surface of
the machine room.
[0019] Each of the second vents may be formed to have a size
increased toward a side surface of the condenser case, from a
connection passage of the condenser case communicated with the
guide duct.
[0020] The condenser may be implemented as refrigerant pipes for
passing a refrigerant are curved a plurality of times on the same
plane.
[0021] The communication portion may be provided so as to have a
decreased sectional area in a flow direction of air by the blowing
fan.
[0022] The refrigerator of the present invention has the following
advantages.
[0023] Firstly, the condenser is installed on an outer surface of
the case not inside the machine room, and the heat emission unit
for emitting heat of the machine room and the condenser is
provided. Accordingly, the machine room may have a decreased
capacity, and heat of the condenser may be effectively emitted.
[0024] Secondly, since the condenser is positioned on a rear
surface of the refrigerator, a degraded appearance of the
refrigerator may be prevented.
[0025] Thirdly, since the condenser is not installed in the machine
room, a position of the machine room may be variable to right and
left portions or a middle portion of a rear surface of the
refrigerator.
[0026] Fourthly, the condenser case having the condenser
accommodated therein may serve to guide a flow of air to each
portion of the condenser, and may prevent a degraded appearance due
to exposure of the condenser. Owing to the condenser case, may be
prevented damage of the condenser when the refrigerator is
moved.
[0027] Fifthly, since an opened surface of the machine room is
formed at a side surface of the case, a flow path of air passing
through the machine room and the condenser case may be simplified.
Accordingly, a flow resistance of air may be reduced, and power
consumption of the blowing fan may be decreased.
[0028] Sixthly, each of the second vents is formed to have a size
increased toward a side surface of the condenser case, from the
connection passage of the condenser case communicated with the
guide duct. This may minimize air leakage occurring through the
second vents before air inside the condenser case is heat-exchanged
with each part of the condenser, in the case when air is introduced
from the connection passage to the condenser case, or from the
condenser case to the connection passage.
[0029] Seventhly, the condenser may be implemented as refrigerant
pipes for passing a refrigerant are curved a plurality of times on
the same plane. This may minimize each thickness of the condenser
and the condenser case. Furthermore, since the condenser may be
installed on an outer surface of the case, the refrigerator may
have an increased installation space.
[0030] Eighthly, the communication portion may be provided so as to
have a decreased sectional area in a flow direction of air
generated by the flowing fan. This causes air to flow with an
increased speed, thereby enhancing a heat emission efficiency of
the condenser or the compressor.

MODES FOR CARRYING OUT THE PREFERRED EMBODIMENTS
[0040] Reference will now be made in detail to the preferred
embodiments of the present invention, examples of which are
illustrated in the accompanying drawings.
[0041] Hereinafter, a refrigerator according to a first embodiment
of the present invention will be explained in more detail.
[0042] FIG. 1 is a perspective view of a heat emission unit
installed on a rear surface of a refrigerator according to a first
embodiment of the present invention, FIG. 2 is an exploded
perspective view of the heat emission unit of FIG. 1, and FIG. 3 is
a sectional view taken along line `I-I` in FIG. 1.
[0043] Referring to FIGS. 1 to 3, a refrigerator according to the
present invention comprises a case 40 having a cooling chamber (S);
a machine room 70 disposed on one side of the case 40, and
configured to accommodate a compressor 50 therein; a condenser 20
disposed on an outer side of the case 40; and a heat emission unit
100 configured to guide external air of the case 40 for heat
emission of the compressor 50 and the condenser 20.
[0044] Hereinafter, each component of the refrigerator according to
the present invention will be explained in more detail.
[0045] The refrigerator according to the present invention
comprises the case 40 that forms appearance thereof, and having a
cooling chamber (S) where food items are cooled to be stored.
[0046] The machine room 70 is formed below a rear surface of the
case 40.
[0047] The compressor 50 is installed at the machine room 70.
[0048] The compressor 50, an evaporator (not shown), the condenser
20, and an expander (not shown) constitute a refrigeration
cycle.
[0049] The condenser 20 is disposed on a rear surface of the case
40, not inside the machine room 70.
[0050] The heat emission unit 100 is provided to guide external air
of the case 40 for heat emission of the compressor 50 and the
condenser 20.
[0051] The heat emission unit 100 includes a machine room cover 101
configured to cover the machine room 70, and having a plurality of
first vents 102; a condenser case 114 configured to fix the
condenser 20 accommodated therein onto a wall surface of the case
40, having a plurality of second vents 114b, and communicated with
one side of the machine room 70; a blowing fan 103 configured to
generate a flow of air passing through the first and second vents
102 and 114b; and a communication portion 113 configured to
communicate an inner side of the machine room 70 with an inner side
of the condenser case 114.
[0052] The communication portion 113 includes a communication duct
113b configured to communicate an inner side of the machine room 70
with a rear side of the case 40, and a guide duct 113a configured
to communicate an inner side of the communication duct 113b with an
inner side of the condenser case 114.
[0053] The communication duct 113b is formed at a lower middle
portion on a rear surface of the case 40.
[0054] Air introduced into one of the first vents 102 and the
second vents 114b is discharged to the other by the blowing fan
103. Accordingly, the compressor 50 inside the machine room 70, and
the condenser 20 inside the condenser case 114 are cooled.
[0055] Preferably, a flow direction of air by the blowing fan 103
is determined so that air having a high temperature by passing
around the condenser 20 can absorb heat from the compressor 50, by
passing around the compressor 50 having a relatively higher
temperature than the condenser 20.
[0056] The blowing fan 103 is implemented as an axial flow fan, and
is installed on a rear surface of the machine room cover 101.
[0057] In the present invention, the condenser 20 is installed
inside the condenser case 114. And, the condenser case 114 is
installed on one outer side of the case 40, not inside the machine
room 70. This allows the cooling chamber (S) to have a more
increased capacity compared to when the condenser is installed at
the machine room 70.
[0058] As the condenser case 114 is installed so as to contact with
external air, heat having conducted to the condenser case 114 from
the condenser 200 installed inside the condenser case 114 is
emitted by air passing through an outer surface of the condenser
case 114. Accordingly, the condenser case 114 serves as a heat
emission plate for emitting heat generated from the condenser 20 to
outside of the refrigerator.
[0059] The condenser 20 is formed in an in-line shaped plate so as
to be inserted into the condenser case 114, i.e., is formed as
refrigerant pipes for passing a refrigerant are curved a plurality
of times. Here, the refrigerant pipe is disposed on the same plane.
An inlet 21 of the condenser 20 is connected to an outlet 51 of the
compressor 50 inside the machine room 70. An outlet 22 of the
condenser 20 is connected to a hot line inlet 25 installed on a
front surface of the refrigerator so as to prevent dew
condensation.
[0060] The condenser case 114 includes a case member 114a having a
prescribed space to accommodate the condenser 20 therein, and
having one opened side surface; a plurality of second vents 114b
penetratingly formed at the case member 114a, and configured to
introduce air thereinto so as to cool the condenser 20; and a
connection passage 113aa disposed on a lower end of the case member
114a in communication with the guide duct 113a, so that the
condenser case 114 and the machine room 70 can be communicated with
each other.
[0061] Preferably, each of the second vents 114a is formed to have
a size increased toward a side surface of the condenser case 114,
from the connection passage 113aa of the condenser case 114
communicated with the guide duct 113a.
[0062] Under this configuration, heat emission of the condenser 20
disposed in the condenser case 114 is uniformly performed.
[0063] In the present invention, the machine room cover 101 may be
installed at the case 40 by a coupling member such as bolts.
However, the machine room cover 101 may be integrally formed with
the case 40.
[0064] Hereinafter, with reference to FIG. 4, will be explained
processes for installing the heat emission unit, and processes for
emitting heat of the compressor and the condenser through the heat
emission unit, in the refrigerator according to the first
embodiment of the present invention.
[0065] FIG. 4 is a perspective view showing a flow of air through
the heat emission unit of FIG. 1.
[0066] Firstly, will be explained processes for coupling the
condenser 20 accommodated in the condenser case 114 to the
compressor 50 installed in the machine room 70, and processes for
fixing the condenser case 114 to the case 40.
[0067] The condenser 20 disposed on a plane in the form of in-line
is inserted into the condenser case 114. Then, the condenser 20 is
fixed to the condenser case 114 by a coupling member (not shown)
such as screws or in a welding manner so as to be prevented from
moving in the condenser case 114.
[0068] The inlet 21 of the condenser 20 is connected to the outlet
51 of the compressor 50 installed inside the machine room 70. And,
the outlet 22 of the condenser 20 is connected to the hot line
inlet 25 installed on a front surface of the refrigerator so as to
prevent dew condensation.
[0069] Then, the opened one side surface of the condenser case 114
having the condenser 20 therein is adhered, by using a coupling
member 114c, to a wall surface of a rear surface of the case
40.
[0070] In correspondence to the communication duct 113b positioned
at the blower fan 103 inside the machine room 70, the guide duct
113a integrally formed on a lower end of the condenser case 114 is
fixed to the blowing fan 103, by the coupling member 114c, as one
opened side thereof is adhered to the blowing fan 103.
[0071] Through the above processes, may be completed the processes
for coupling the condenser 20 accommodated in the condenser case
114 to the compressor 50, and the processes for fixing the
condenser case 114 to a rear wall of the case 40.
[0072] The blowing fan 103 is coupled to a rear wall of the case 40
so as to face the compressor 50. And, the machine room cover 101 is
installed on a rear wall of the case 40 by a coupling member, so as
to cover the blowing fan 103.
[0073] Hereinafter, will be explained processes for emitting heat
of the compressor 50 and the condenser 20 by the heat emission unit
100 provided on a rear wall of the case 40.
[0074] A refrigerant introduced into the refrigerator via an
evaporator (not shown) in a low-temperature low-pressure gaseous
state is compressed into a high-temperature high-pressure gaseous
state by the compressor 50, thereby being used to heat the
compressor 50. Therefore, the compressor 50 requires to be cooled
so as to prevent damage and lowering of a driving efficiency
thereof.
[0075] The compressor 50 is cooled by a flow of air generated by
the blowing fan 103 and discharged to or introduced into the first
vents 102.
[0076] The refrigerant discharged through the compressor 50 is
condensed into a high-temperature high-pressure liquid state via
the condenser 20. In this case, a large amount of heat occurs
around the condenser 20. Therefore, the condenser 20 requires to be
cooled so as to prevent damage and lowering of a driving efficiency
thereof.
[0077] The condenser 20 is cooled by a flow of air generated by the
blowing fan 103 and discharged to or introduced into the second
vents 114b.
[0078] The reason is because a flow of air by the blowing fan 103
also occurs at the condenser 20 through the communication portion
113.
[0079] As the condenser case 114 having the condenser 20
accommodated therein in a fixed state is installed so as to
directly contact with external air, heat having conducted from the
condenser 200 is emitted out by natural convection of air passing
through an outer side of the condenser case 114.
[0080] Here, the condenser case 114 serves as a heat emission
plate.
[0081] Here, a flow direction of air is determined such that air
having served to cool one of the compressor 50 and the condenser 20
can be supplied to the other for cooling.
[0082] Since the compressor 50 has a relatively higher temperature
than the condenser 20, a flow direction of air is preferably set so
that the condenser 20 can be firstly cooled and then the compressor
50 can be cooled.
[0083] In conclusion, since external air can absorb heat of the
compressor 50 and the condenser 20 to dissipate the heat by the
heat emission unit, heat emission of the machine room 70 and the
condenser 20 is smoothly performed. Also, the machine room 70 can
have a compact configuration.
[0084] Next, will be explained state changes of a refrigerant
circulating in the refrigeration cycle constituted by the
compressor 50 and the condenser 20.
[0085] A refrigerant introduced into the compressor 50 through the
evaporator (not shown), and pressurized into a high-temperature
high-pressure gaseous state from a low-temperature low-pressure
gaseous state flows to the condenser 20 accommodated in the
condenser case 114 fixed to the case 40. Then, the refrigerant
introduced into the condenser 20 has a state change to a
room-temperature high-pressure liquid state through a heat emission
process by the condenser 20.
[0086] Here, the refrigerant having complete a condensation process
by the condenser 20 is introduced into the hot line inlet 25
connected to the outlet 22 of the condenser 20, and then flows on
an entire part of a hot line (not shown) installed on a front
surface of the refrigerator for prevention of dew condensation.
Then, the refrigerant moves into an expansion valve (not shown)
through an inlet of the expansion valve connected to an outlet of
the hot line.
[0087] The refrigerant introduced into the expansion valve is
depressurized into a state that can be easily evaporated, through a
heat exchange by the evaporator. The refrigerant is introduced into
the evaporator, and then is evaporated by an absorption reaction by
which internal heat of the refrigerator is absorbed. The evaporated
refrigerant is changed into a low-temperature low-pressure gaseous
state, thus to be introduced into the compressor 50 again.
[0088] The refrigeration cycle is completed through the above
processes, and is repeated to discharge the generated cool air into
the refrigerator. Accordingly, the refrigerator can have a lowered
internal temperature.
[0089] Hereinafter, a refrigerator according to a second embodiment
of the present invention will be explained with reference to FIGS.
5 and 6. Explanations for the same components as those of the first
embodiment will be omitted.
[0090] FIG. 5 is a perspective view of a heat emission unit
installed on a rear surface of a refrigerator according to a second
embodiment of the present invention, and FIG. 6 is a sectional view
taken along line `II-II` in FIG. 5.
[0091] Referring to FIGS. 5 and 6, the refrigerator according to a
second embodiment is different from the refrigerator according to a
first embodiment in the aspects of positions of a machine room
cover 201 and a communication portion 213.
[0092] The machine room 270 has an opened surface toward a side
surface of the case 40, and a machine room cover 201 covers the
opened surface. A communication duct 213b is formed on a rear
surface of the case 40 so as to be adjacent to the opened surface
of the machine room 270.
[0093] Each of a plurality of the second vents 114b formed at the
condenser case 114 has a size increased to both side surfaces of
the condenser case 114, from the connection passage 113aa of the
condenser case 114 communicated with the guide duct 213a.
[0094] Under this configuration, air passing through the machine
room 270 and the condenser case 114 can smoothly flow. This allows
the blowing fan for generating a flow of air to have reduced power
consumption.
[0095] Hereinafter, a refrigerator according to a third embodiment
of the present invention will be explained with reference to FIGS.
7 and 8. Explanations for the same components as those of the first
embodiment will be omitted.
[0096] FIG. 7 is a perspective view of a heat emission unit
installed on a rear surface of a refrigerator according to a third
embodiment of the present invention, and FIG. 8 is a sectional view
taken along line `III-III` in FIG. 7.
[0097] Referring to FIGS. 7 and 8, the refrigerator according to a
third embodiment is different from the refrigerator according to a
first embodiment in the aspect of a communication portion 313.
[0098] The communication portion 313 includes a communication duct
313b configured to communicate an inner side of the machine room 70
with a rear side of the case 40, and a guide duct 113a configured
to communicate an inner side of the communication duct 313b and an
inner side of the condenser case 114. The communication portion 313
is provided such that the communication duct 313b and the guide
duct 113a can have a decreased sectional area in a flow direction
of air, respectively.
[0099] Under this configuration, as air flows with an increased
speed, heat of the condenser or the compressor is more effectively
emitted. Hereinafter, a refrigerator according to a fourth
embodiment of the present invention will be explained with
reference to FIG. 9. Explanations for the same components as those
of the first embodiment will be omitted.
[0100] FIG. 9 is a perspective view showing a condenser case and a
blowing fan of a refrigerator according to a fourth embodiment of
the present invention.
[0101] Referring to FIG. 9, the refrigerator according to a fourth
embodiment is different from the refrigerator according to a first
embodiment in the aspects of an installation position and a type of
a blowing fan 403.
[0102] Here, the blowing fan 403 is implemented as a cross flow
fan, and is installed at one side of the guide duct 113a.
[0103] As the blowing fan 403 is installed at a position where a
flow direction of air frequently changes, a cooling efficiency by
the compressor 50 and the condenser 20 can be more enhanced.
[0104] It will also be apparent to those skilled in the art that
various modifications and variations can be made in the present
invention without departing from the spirit or scope of the
invention. Thus, it is intended that the present invention cover
modifications and variations of this invention provided they come
within the scope of the appended claims and their equivalents.
