Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of Korean Patent
Application No. 2007-34423, filed on Apr. 6, 2007 in the Korean
Intellectual Property Office, the disclosure of which is
incorporated herein by reference.
BACKGROUND
[0002] 1. Field
[0003] The present invention relates to a refrigerator, and, more
particularly, to a refrigerator including a blowing unit optimized
for a bottom type condenser.
[0004] 2. Description of the Related Art
[0005] A refrigerator is a machine that generates cool air using
the movement of heat due to the phase change of refrigerant and
supplies the cool air to a storage compartment, in which various
kinds of food are stored, through a specific channel to maintain
the freshness of the food for a long time. A refrigerator generally
includes a compressor to compress a refrigerant, a condenser to
condense the compressed refrigerant, an expansion device to expand
the condensed refrigerant and an evaporator to evaporate the
expanded refrigerant to cool a storage compartment.
[0006] The compressor and the condenser must be cooled using
external air. For this reason, the compressor and the condenser are
mounted in a machine compartment partitioned from the storage
compartment. In the machine compartment are also mounted a blowing
unit, i.e., a blowing fan, to blow air necessary to cool the
compressor and the condenser.
[0007] The blowing fan mounted in the machine compartment is an
axial flow fan. The axial flow fan is mounted in the machine
compartment in consideration of the direction of air flow occurring
at the rear of a main body of the refrigerator, where no large
resistance is applied to the axial flow fan, which is developed in
consideration of the flow direction.
[0008] In the refrigerator with the above-stated construction, the
air, blown through the axial flow fan, is discharged through a
discharge port formed at the rear of the main body. However, when
air is blown through the axial flow fan, then discharged to the
rear of the main body, the discharge of the air may be impeded.
[0009] The difficulty of efficient air discharge is especially
present for a built-in type refrigerator. The main body of such
refrigerators, are mounted in the wall of a building further
impeding the smooth discharge of air to the rear of the main
body.
[0010] Furthermore, an increase in power consumption of the blowing
unit results from the impedance of smooth discharge of air.
SUMMARY
[0011] Additional aspects and/or advantages 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.
[0012] Therefore, it is an aspect of the invention to provide a
refrigerator that is capable of smoothly discharging air using a
blowing unit.
[0013] It is another aspect of the invention to provide a
refrigerator that is capable of reducing the power consumption
through the smooth discharge of air by the blowing unit.
[0014] In accordance with one embodiment, the present invention
provides a refrigerator including a main body having a storage
compartment defined therein, a condenser mounted at the bottom of
the main body, and a blowing unit to blow air having passed the
condenser, wherein the blowing unit includes a centrifugal fan and
a blowing guide member to guide air blown by the centrifugal
fan.
[0015] In an embodiment, the blowing guide member includes a fan
casing surrounding the centrifugal fan and a guide duct to guide
air introduced through the fan casing.
[0016] In an embodiment, the fan casing has a suction port, through
which air blown by the centrifugal fan is suctioned.
[0017] In an embodiment, the guide duct communicates with the fan
casing to guide the air suctioned through the suction port.
[0018] In an embodiment, the guide duct has a discharge port,
through which the air, suctioned through the suction port and
guided, is discharged, and the discharge port is directed to the
front of the main body.
[0019] In an embodiment, the main body is provided at the bottom
thereof with an air discharge channel having one end communicating
with the discharge port of the guide duct to discharge the air,
guided along the guide duct and discharged, to the front of the
main body.
[0020] Additional aspects and/or advantages of the invention will
be set forth in part in the description which follows and, in part,
will be obvious from the description, or may be learned by practice
of the invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] Reference will now be made in detail to the embodiments of
the present invention, examples of which are illustrated in the
accompanying drawings, wherein like reference numerals refer to
like elements throughout. The embodiments are described below to
explain the present invention by referring to the figures.
[0026] FIG. 1 is a sectional view illustrating a refrigerator
according to an embodiment of the present invention, and FIG. 2 is
an exploded perspective view of the refrigerator.
[0027] Referring to FIGS. 1 and 2, the refrigerator according to an
embodiment of the present invention includes a main body 10 having
a storage compartment 12, which is divided into a refrigerating
compartment and a freezing compartment by a middle partition (not
shown), defined therein. To the front of the storage compartment 12
are mounted doors to open and close the refrigerating compartment
and the freezing compartment.
[0028] To the inside rear wall of the storage compartment 12 is
mounted an evaporator 16 to generate cool air. Above the evaporator
16 is mounted a cool air circulation fan 18 to blow internal air in
the storage compartment 12 such that the internal air is circulated
through the evaporator 16. The evaporator 16 is disposed in a cool
air generating compartment 20 defined inside the storage
compartment 12.
[0029] Below the cool air generating compartment 20 is formed a
cool air inlet port 22, through which the internal air in the
storage compartment 12, i.e., the cool air, is introduced into the
cooling air generating compartment 20 such that the air passes
through the evaporator 16. Below the evaporator 16 is formed a cool
air outlet port 24, through which the cool air, having passed
through the evaporator 16, is discharged into the storage
compartment 12 by the cool air circulation fan 18.
[0030] At the front side of the bottom of the main body 10 is
mounted a condenser 42 to change a high-temperature and
high-pressure refrigerant gas into a low-temperature and
high-pressure refrigerant liquid. The condenser 42 is a bottom type
condenser mounted in a built-in type refrigerator to increase the
capacity of the storage compartment 12. That is, the condenser 42
according to an embodiment of the present invention includes
superior space efficiency as compared to a conventional condenser,
thus increasing the capacity of the refrigerator.
[0031] At the rear side of the bottom of the main body 10 is
defined a machine compartment 30. Access panel 23 may be affixed to
main body 10. Access panel 23 can be removed and later reaffixed to
main body 10 to allow access to machine compartment 30 for
servicing. In the machine compartment 30 are mounted a compressor
32 to change a gaseous refrigerant into a high-temperature and
high-pressure refrigerant gas and a blowing unit 34 to blow air
having passed through the condenser 42 and the compressor 32.
[0032] As shown in FIG. 3, the blowing unit 34 includes a blowing
fan 35 and a blowing guide member 36 to guide air blown by the
blowing fan.
[0033] The blowing fan suctions air into the machine compartment
30, during the operation of the blowing fan, to cool the condenser
42 and the compressor 32. According to an embodiment of the present
invention, the blowing fan is not a conventional axial flow fan but
a multi-blade centrifugal fan 35. At one side of the centrifugal
fan 35 is mounted a motor 35a to drive the centrifugal fan 35.
[0034] The blowing guide member 36 includes a cylindrical fan
casing 37 surrounding the centrifugal fan 35 and a guide duct 38
communicating with the fan casing 37 to guide air introduced
through the fan casing 37.
[0035] At one side of the fan casing 37 is formed a suction port
37a, through which air is suctioned during the rotation of the
centrifugal fan 35.
[0036] The guide duct 38 communicates with the fan casing 37, as
described above. During the rotation of the centrifugal fan 35, the
guide duct 38 guides the air suctioned through the suction port 37a
of the fan casing 37 such that the air is discharged toward the
front of the main body 10. To this end, a discharge port 38a is
formed at one side of the guide duct 38 such that the discharge
port 38a is directed to the front of the main body 10.
[0037] At the bottom of the main body 10 is also formed an air
supply channel 28 to guide the introduction of external air into
the machine compartment 30 and an air discharge channel 29 to guide
the discharge of the air from the machine compartment 30. The air
supply channel 28 and the air discharge channel 29 extend in the
forward-and-backward direction of the main body 10 such that the
interior of the machine compartment 30 communicates with the front
side of the bottom of the main body 10. One end of the air
discharge channel 29 communicates with the discharge port 38a of
the guide duct 38, and the other end of the air discharge channel
29 communicates with a discharge port (not shown) formed at the
lower front of the main body 10.
[0038] Hereinafter, the air circulating operation of the
refrigerator according to an embodiment of the present invention
will be described.
[0039] First, when the centrifugal fan 35 is rotated by the motor
35a, air outside the machine compartment is introduced into the
machine compartment 30 while the air is heat-exchanged with the
bottom type condenser 42. The air, introduced into the machine
compartment 30, cools the compressor 32 by the continuous rotation
of the centrifugal fan 35.
[0040] The air inside the machine compartment 30, having passed
through the condenser 42 and the compressor 32, is introduced into
the fan casing 37, surrounding the centrifugal fan 35, through the
suction port 37a by the centrifugal fan 35. The air, introduced
into the fan casing 37, is guided along the guide duct 38, and is
then discharged through the discharge port 38a of the guide duct
38.
[0041] The air, discharged through the discharge port 38a of the
guide duct 38, moved to the air discharge channel 29, in which the
air is discharged to the front of the main body 10.
[0042] According to an embodiment of the present invention,
therefore, the air, having passed through the bottom type condenser
42 and the compressor 32, is discharged to the front of the main
body 10 by the blowing unit 34, which includes the centrifugal fan
35 and the blowing guide member 36 to guide the air blown by the
centrifugal fan 35. Consequently, the smooth discharge of air is
accomplished. In addition, the power consumption of the blowing
unit 34 is reduced through the discharge of air to the front of the
main body 10.
[0043] Furthermore, the air, having passed through the bottom type
condenser 42 and the compressor 32, is blown using the centrifugal
fan 35. Consequently, efficiency is maintained through a relatively
small flow resistance, as compared to that of the conventional
axial flow fan.
[0044] As apparent from the above description, the refrigerator
according to an embodiment of the present invention has the effect
of discharging the air, having passed through the bottom type
condenser and the compressor, to the front of the main body by the
centrifugal fan and the blowing guide member, thereby accomplishing
the smooth discharge of air.
[0045] Furthermore, the refrigerator according to an embodiment of
the present invention has the effect of smoothly discharging air to
the front of the main body, thereby reducing the power consumption
necessary to discharge air.
[0046] 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.
