specifically, the present invention relates to an evaporator having
a duct integrated therewith, in which a circulating duct and an
evaporator are fabricated as one module for reducing an error
caused by a worker, a performance deviation and working
man-hours.
BACKGROUND ART
[0002] In general, the refrigerator is provided with a compressor
for elevating a temperature and a pressure of low temperature, low
pressure gaseous refrigerant to a high temperature and high
pressure gaseous refrigerant, and a condenser for cooling and
condensing the high temperature and high pressure gaseous
refrigerant into liquidus refrigerant by using heat exchange with
outdoor air.
[0003] In addition to this, the refrigerator is provided with a
capillary tube having a diameter smaller than a diameter of other
parts for decompressing the refrigerant introduced thereto from the
condenser, and an evaporator for evaporating the refrigerant from
the capillary tube to low temperature and low pressure refrigerant
for absorbing heat from an inside of the refrigerator.
[0004] The refrigerator is also provided with a freezing chamber
having cold air introduced thereto from the evaporator directly for
maintaining a chamber temperature of about -18.degree. C., and a
refrigerating chamber having the cold air introduced thereto from
the freeing chamber for maintaining a chamber temperature of about
0.about.7.degree. C.
[0005] There are a machinery room on a lower portion of a rear side
of the refrigerating chamber having the compressor and the
condenser mounted thereto, and a cold air supply unit in rear of
the freezing chamber isolated therefrom with a rear wall thereof
having a cooling fan for forced blow of the cold air from the
evaporator to the freezing chamber and a defrosting heater for
removing frost from a surface of the evaporator mounted
thereto.
[0006] The cold air cooled down by means of heat exchange at the
evaporator as the air is deprived of heat by refrigerant passes a
cold air outlet in rear walls of the freezing chamber and the
refrigerating chamber through the circulating duct and discharged
and circulated in the refrigerator by a fan to drop temperatures of
the freezing chamber and

MODE FOR THE INVENTION
[0018] Reference will now be made in detail to the specific
embodiments of the present invention, examples of which are
illustrated in the accompanying drawings. Wherever possible, the
same reference numbers will be used throughout the drawings to
refer to the same or like parts.
[0019] Referring to FIG. 1, the evaporator having a duct integrated
therewith includes an evaporator 1 and a circulating duct 20.
[0020] The evaporator 10 is used for generating cold air, and
includes a heat exchanger tube 11 having a refrigerant pipe 12
extended from a top side thereof and connected to a refrigerant
pipe 12 in a refrigerator by welding.
[0021] The circulating duct 20 is mounted in a cold air supply
portion 4 (see FIG. 3) located on one side of a freezing chamber
for guiding the cold air from the evaporator 10 to a refrigerating
chamber and/or the freezing chamber.
[0022] The circulating duct 20 includes a duct portion 30 and a
mounting portion 40, wherein the duct portion 30 is mounted to a
top side of the cold air supply portion 4 and extended extensively
to the refrigerating chamber and/or the freezing chamber, and may
have a plurality of pass through holes 31 along an outside
surface.
[0023] The duct portion 30 has an enlarged portion 32 on a lower
side with a slope and insertion holes 33 for pass through of the
refrigerant pipe 12 of the evaporator 10.
[0024] The mounting portion 40 is connected to a bottom edge of the
duct portion 30 and extended down extensively, and has a rear side
of an opened box shape, a fan mounting portion 41 on an upper side
for mounting a cooling fan (not shown) thereto, and an inside space
for holding the evaporator 10.
[0025] Particularly, the mounting portion 40 has a cover 42 on the
opened rear side for easy holding of the evaporator 10, wherein the
cover 42 has mounting projections 43 at regular intervals along
edges and the mounting portion 40 has mounting holes 44 in opposite
sides at regular intervals in conformity with the mounting
projections 43.
[0026] As another embodiment of the present invention, instead of
the mounting projections 43 of the cover 42 and the mounting holes
44 of the mounting portion 40 for holding the evaporator 10, a door
may be provided for rotatably opening/closing the rear side of the
mounting portion 40, or other system may be provided for easy
holding of the evaporator 10 within the mounting portion 40.
[0027] It is preferable that the mounting portion 40 fabricated as
one module thus is mounted to a conventional inner case (not shown)
which forms an inner surface of the refrigerator with conventional
fastening means (screws or the like) in a state the evaporator 10
is received in and secured to the mounting portion 40.
[0028] As one embodiment, though the evaporator is shown as a
fin-tube type evaporator in the drawing, having a meander of
repeatedly bent copper heat exchanger tube 11 with aluminum cooling
fins 13 closely inserted on an outside of the tube 11, a coaxial
type or jacket type heat exchanger may be used as required.
[0029] Unexplained reference numeral 50 in the drawing denotes an
accumulator for separating liquid refrigerant from gaseous
refrigerant to prevent liquid back for protecting the compressor,
thereby preventing turbulence of the liquid refrigerant in the
evaporator.
[0030] The operation of the evaporator having a duct integrated
therewith of the present invention will be described.
[0031] Referring to FIG. 1, as one embodiment of the present
invention, in a state the evaporator 10 is placed in the mounting
portion 40, the evaporator 10 and the circulating duct 20 are
integrated by passing the mounting projections 43 on the edges of
the cover 42 through the mounting holes 44 in the opposite edges of
the mounting portion 40, respectively.
[0032] In this instance, the refrigerant pipe 12 extended from the
top side of the evaporator 10 is passed through the insertion holes
33 in the enlarged portion 32 of the circulating duct 20 to expose
the refrigerant pipe 12 to an outside of the enlarged portion 32,
and welded to the refrigerant pipe 12 in an inside of the
refrigerant, and finally, the evaporator 10 and the mounting
portion 40 integrated as a module is mounted to an inner case of
the refrigerator.
[0033] Eventually, because the evaporator 10 and the circulating
duct can be mounted in the refrigerator as a mode of one component,
a work load required for fastening can be reduced,
significantly.
[0034] It will 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 the modifications
and variations of this invention provided they come within the
scope of the appended claims and their equivalents.
