- The refrigerator of the embodiments is configured such that the evaporator accommodating part of the depression part formed in the barrier within which the heat insulator is filled is formed to be stepped to the blowing unit accommodating part.
- Accordingly, the heat insulator is formed to be thicker in a part which the evaporator is disposed in and therefore has a relatively low temperature, thereby preventing influence on change of the temperature of the inside of the refrigerating compartment.
- Furthermore, the evaporator is located on the freezing compartment, thereby minimizing the whole thickness of the barrier and, at the same time, maintaining the heat insulation performance of the refrigerating compartment.
- In addition, a blowing unit accommodating part is additionally depressed, thereby securing a space which allows the cold air of the evaporator to be introduced into a blowing fan and, therefore, improving the flow performance of the cold air.
- In addition, the blowing unit accommodating part and the cold air passage are formed to be depressed in the barrier, thereby making the flow of the cold air within the barrier smooth, and, at the same time, making the entire structure of the barrier simple.
- Furthermore, the barrier cover to shield the depression part is configured to include a lower cover to shield the evaporator accommodating part and an upper cover to shield the blowing unit accommodating part and the cold air passage.
- Accordingly, it is possible to make the assembly of the evaporator cover to be easy, and to provide a more easy fixing structure by the passage guide part and the evaporator guide part formed in the upper cover and the lower cover, thereby making the assembly easy.
- Further, the cover mounting portion in which the barrier cover is mounted is formed to be depressed, so that the barrier cover is mounted to be accommodated in the inside of the barrier, and the coupling member is fastened to the fastening part by penetrate through the fastening part, thereby providing a more firm coupling structure.
- Further, a heat insulator different from the foamed heat insulator within the barrier is provided in the depression part at which the thickness of the barrier is relatively is thin, thereby improving heat insulation performance of the barrier.
- Further, heat insulation for the depression part at which heat insulation is relatively weak is possible, thereby maintaining the temperature of the refrigerating compartment. Further, heat insulation performance is maintained due to additional heat insulation by the heat insulator, so that a number of configurations including the evaporator and the blowing unit and the like are provided in the inside of the barrier, thereby maintaining the thickness of the barrier. Accordingly, it is possible to prevent the interior volume of the refrigerator from decreasing due to the barrier.
- Further, the thickness of the heat insulator is relatively thin than other parts at a location corresponding the barrier in which the evaporator and the blowing unit is accommodated, and the condensation prevention member is formed in the side surface of the barrier for the refrigerating compartment corresponding thereto.
- The condensation prevention part is formed in a concave and convex shape, so that when air within the refrigerating compartment is circulated, recirculation of air occurs in the inside of the heat insulating grooves formed in the condensation prevention part thereby forming an air layer between the surface of the barrier and the inside of the refrigerating compartment. Accordingly, the heat delivery rate of the surface of the barrier is lowered, thereby preventing condensation from occurring due to temperature difference on the surface of the barrier.
- Accordingly, the heating member for removal of frost generated in the inside of the barrier is provided in the depression part and the defrost water discharge part to discharge defrost water generated upon defrosting from the inside of the depression part to the machine room is formed. Therefore, there is an advantage in that the defrost water is smoothly discharged.
- Further, the refrigerant pipe guide part to guide the refrigerant pipe coupled to the evaporator to the machine room is formed in the barrier and a line guide part to guide power line coupled to the electric parts provided in the inside of the depression part is provided. Accordingly, when the number of electric parts including the evaporator is mounted in the inside of the barrier, the assembly thereof is easily made.

FIGS. 1 and 2 , the exterior shape of therefrigerator 1 according to an embodiment of the present invention is formed by acabinet 10 defining a storage space and adoor 20 to open and close the storage space. - The
cabinet 10 is divided into left and right sides by abarrier 100 to define arefrigerating compartment 40 and a freezingcompartment 30 respectively. The refrigeratingcompartment 40 and the freezingcompartment 30 are configured to have a plurality of drawers and shelves therein and to preserve various foods therein.

FIG. 5 is a front view showing the shape of the depression part of the barrier.FIG. 6 is a perspective view taken along line 6-6′ ofFIG. 5 . - Referring to
FIGS. 3 to 6 , thebarrier 100 is formed to be elongated up and down inside thecabinet 10, and anevaporator 110 and ablowing unit 130 are mounted therein. - The external shape of the
barrier 100 is formed by acasing 150 defining the internal spaces of therefrigerating compartment 40 and the freezingcompartment 30 and aheat insulator 300 is foamed and filled within thecasing 150. Theheat insulator 300 is filled evenly throughout the internal space of thebather 100. - Meanwhile, a
depression part 200 is formed on the left side surface of thebarrier 100, that is, the surface exposed to cold air from the freezingcompartment 30. Furthermore, theevaporator 110 and theblowing unit 130 which will be described below are accommodated in thedepression part 200. - Specifically, the
depression part 200 includes anevaporator accommodating part 210 in which theevaporator 110 for generation of cold air is accommodated, a blowingunit accommodating part 220 which accommodates theblowing unit 130, and acold air passage 230 which supplies the cold air generated by theevaporator 110 to therefrigerating compartment 40 and the freezingcompartment 30. - The
evaporator accommodating part 210 which is formed in the lower side of thebarrier 100 is formed to be larger than theevaporator 110 to fully accommodate theevaporator 110 and may be formed to be depressed greater than the thickness of theevaporator 110. That is, theevaporator accommodating part 210 is formed to be depressed to a sufficient depth such that theevaporator 110 is not extruded outside thebarrier 100 when theevaporator 110 is mounted therein. Furthermore, theevaporator 110 may be mounted to be fixed to theevaporator accommodating part 210 using a separate fixing member or a fixing structure. - Furthermore, a
cold air inlet 212 is formed in the lower end of theevaporator accommodating part 210. The cold air inlet 121 is a passage through which the cold air within therefrigerating compartment 40 returns to theevaporator 110 and may be formed on rear side of theevaporator accommodating part 210. - A
suction grill 214 is formed in thecold air inlet 212 to prevent foreign substances from being introduced from the inside of the refrigerating compartment and the outside of the refrigerator to theevaporator accommodating part 210. The cold air inlet 121 may be formed at a location corresponding to a location at which the drawers and the like of therefrigerating compartment 40 are provided not to be exposed to the outside when the refrigeratingcompartment door 24 is opened. - Furthermore, a
drain fan 120 for discharging defrost water produced upon defrosting frost may be further formed on the bottom of theevaporator accommodating part 210. Thedrain fan 120 is formed to be tilted to one side and may be formed to be in communication with the machine room of thecabinet 10. - The
drain fan 120 may be provided as a separate member to be mounted on the bottom of theevaporator accommodating part 210 corresponding to the lower side of theevaporator 110. If required, the bottom thedepression part 200 is formed be tilted to enable thedepression part 200 to play the role of thedrain fan 120. - Meanwhile, the blowing
unit accommodating part 220 is formed on the upper side of theevaporator accommodating part 210. In addition, theblowing unit 130 disposed on the blowingunit accommodating part 220 includes amotor 132, a blowingfan 134 and ashroud 136. - Specifically, the
motor 132 is for providing a rotating force to operate the blowingfan 134, and an electric motor generally used may be applicable thereto. Furthermore, the blowingfan 134 is mounted on the rotating shaft of themotor 132. As the blowingfan 134, a centrifugal fan for introducing air in the direction of the rotating shaft and discharging it in a radial direction may be used, a turbo fan having excellent blowing capability may be used. The thickness of thebarrier 100 may be slim by applying the turbo fan. Furthermore, theshroud 136 functions to guide the cold air passed through theevaporator 110 to be introduced to the blowingfan 134. The mount structure of theblowing unit 130 is described in detail below with reference the drawings. - Meanwhile, cold
air guide part 222 is formed on both sides of the blowingunit accommodating part 220. The coldair guide part 222 guides the cold air from theevaporator accommodating part 210 to be directed to the center of theshroud 136. For this, the coldair guide part 222 is formed such that its width becomes narrow from the lower side to the upper side. - Specifically, the lower end of the blowing
unit accommodating part 220 has a width identical to that of the upper end of theevaporator accommodating part 210, and the upper end of the blowingunit accommodating part 220 is formed to have a width identical to that of the lower end of thecold air passage 230. - Furthermore, the cold
air guide part 222 may be formed to be tilted or rounded, and guides the cold air moving along with the coldair guide part 222 to be directed to the center of theshroud 136. - Furthermore, the blowing
unit accommodating part 220 is formed to be depressed greater than theevaporator accommodating part 210 and thecold air passage 230 which will be described below. Herein, the surface of the inlet of theshroud 136 is spaced from the surface of the blowingunit accommodating part 220. Accordingly, the cold air rising from theevaporator accommodating part 210 can be smoothly moved into anorifice 137 formed around the center of theshroud 136 through a space spaced between the blowingunit accommodating part 220 and theshroud 136. - The
evaporator accommodating part 210 and the blowingunit accommodating part 220 have different depression depths to be stepped with respect to each other. Therefore, the thicknesses of theheat insulators 300 within thebarrier 100 corresponding to theevaporator accommodating part 210 and the blowingunit accommodating part 220 are become different. In order words, since theevaporator accommodating part 210 is relatively depressed less than the blowingunit accommodating part 220, the thickness of theheat insulator 300 corresponding to theevaporator accommodating part 210 relatively becomes thicker. As a result, it is possible to efficiently prevent the cold air from the evaporator 110 from being delivered to therefrigerating compartment 40 due to heat conduction. - Furthermore, since the blowing
unit accommodating part 220 is relatively depressed greater than theevaporator accommodating part 210, a passage for smooth flowing of cold air to theblowing unit 130 is ensured. Furthermore, the thickness of theheat insulator 300 corresponding to the blowingunit accommodating part 220 is relatively thin, but the heat insulation of theblowing unit 130 having a temperature relatively higher than that of theevaporator 110 is sufficiently possible. - Meanwhile, the stepped parts of the
evaporator accommodating part 210 and the blowingunit accommodating part 220 are coupled to each other by acoupling part 240. Thecoupling part 240 forms an interface between the evaporatoraccommodating part 210 and theblowing unit 130 and is formed to be tilted. Accordingly, the cold air within theevaporator accommodating part 210 may be caused to be smoothly introduced into the inside of the blowingunit accommodating unit 220. - The
cold air passage 230 is formed on the upper side of the blowingunit accommodating part 220. Thecold air passage 230 is to guide the cold air discharged from the outlet 139 of theshroud 136 into the refrigerating compartment and the freezingcompartment 30, and is formed to be extended to the upper side of thebarrier 100. The width of the outlet 139 of theshroud 136 may be formed to be identical to the width of thecold air passage 230. Furthermore, thecold air passage 230 may be formed to have a width identical to the width of the opened upper end of the blowingunit accommodating part 220. - Furthermore, the
cold air passage 230 is formed to be depressed less than the blowingunit accommodating part 220. Therefore, the thickness of theheat insulator 300 on a location corresponding to thecold air passage 230 may be formed to be thicker than the thickness of the heat insulator on a location corresponding to the blowingunit accommodating part 220. Accordingly, the cold air flowing along thecold air passage 230 can be blocked not to be delivered to therefrigerating compartment 40 due to heat conduction. - The
cold air passage 230 is shielded by abarrier cover 400 which will be described below, thereby forming the cold air passage completely. Furthermore, acold air outlet 232 is formed in the upper end of thecold air passage 230. Thecold air outlet 232 is located in the upper center of thebarrier 100 and may be exposed to therefrigerating compartment 40. In addition, anoutlet grill 234 to guide the direction of the discharged cold air may be further formed in thecold air outlet 232. - Meanwhile, a cold
air distribution device 140 is provided in thecold air outlet 232. The coldair distribution device 140 is for selectively supplying the cold air supplied from thecold air passage 230 to thecold air outlet 232, and is formed in a size corresponding to thecold air outlet 232. Furthermore, the coldair distribution device 140 may be formed to have the structure of a damper and thecold air outlet 232 is formed to be selectively opened and closed. Accordingly, when the coldair distribution device 140 is opened, some of the cold air guided through thecold air passage 230 is discharged to thecold air outlet 232, thereby being introduced into the refrigerating compartment. On the other hand, when the coldair distribution device 140 is closed, the whole of the cold air guided through thecold air passage 230 is discharged to the freezing compartment. - Meanwhile, the
depression part 200 is shielded by thebarrier cover 400. Thebarrier cover 400 is formed to have a plate shape, and shields thedepression part 200 to form a part of the left side surface of thebarrier 100, that is, a part of the wall of the inside of the freezingcompartment 30. Furthermore, thebarrier cover 400 is formed to have the same plane as the side surface of thebarrier 100 when being mounted on thebarrier 100. - The
barrier cover 400 may be formed of one plate material, whereas may be formed to be divided into a plurality of parts if required. For example, thebarrier cover 400 may be formed to be divided into a part covering theevaporator accommodating part 210 and a part covering theblowing unit 120 and thecold air passage 230. - In addition, the right side surface of the
barrier 100 opposite to the surface on which thebarrier cover 400 is mounted is also formed to have a smooth plane without protruding the outside, thereby forming a part of the wall of the inside of therefrigerating compartment 40. Accordingly, the both side surfaces of thebarrier 100 all may be formed to be flat. - Furthermore, a mounting
guide 424 having a shape corresponding to the external shape of theevaporator 110 is formed on the rear surface of thebarrier cover 400 corresponding to theevaporator 110, thereby assisting the fixation of theevaporator 110. - Meanwhile, a
cold air inlet 422 is formed in the lower end of thebarrier cover 400 corresponding to theevaporator accommodating part 210. Thecold air inlet 422 is a part into which the cold air of the freezing compartment is introduced, and guides the cold air of the freezingcompartment 30 to be introduced into theevaporator accommodating part 210. - Furthermore, a
cold air outlet 412 is formed in the upper part of thebarrier cover 400 corresponding to thecold air passage 230. A number ofcold air outlets 412 may be formed at uniform intervals, and enable the cold air rising along thecold air passage 230 to be discharged to the freezingcompartment 30. - Meanwhile, coupling ends 416 and 426 to mount the
barrier cover 400 are further formed on the both side ends of thebarrier cover 400. Furthermore, a fastening member, such as a screw, is inserted into thecoupling end barrier cover 400 to be fixed to the left side surface of thebarrier 100. Furthermore, the side surface of thebarrier 100 corresponding to thecoupling end coupling end barrier 100. -
FIG. 7 is a diagram showing the flow state of cold air within the bather viewed from the freezing compartment, and -
FIG. 8 is a diagram showing the flow state of cold air within the barrier viewed from the refrigerating compartment; - Referring to
FIGS. 7 and 8 , when power is supplied to therefrigerator 1, a freezing cycle inside therefrigerator 1 is operated. Due to the operation of the freezing cycle, air in contact with theevaporator 110 is cooled, thereby generating cold air. - First, describing a state in which cold air is supplied to the freezing
compartment 30 with reference toFIG. 7 , the blowingfan 134 is operated by the operation of themotor 132 in order to supply cold air to the freezingcompartment 30. Due to the operation of the blowingfan 134, the cold air of the freezingcompartment 30 introduced through thecold air inlet 422 is heat-exchanged by theevaporator 110 to be more cold state, and is then moved upward according to the operation of the blowingfan 134. - The cold air moved upward from the
evaporator accommodating part 210 is moved into inside the blowingunit accommodating part 220 along thecoupling part 240, is then introduced into theorifice 137 of theshroud 136 by the guide of the coldair guide part 222. - The cold air introduced into the
shroud 136 is discharged into the outlet 139 of theshroud 136 to be guided to thecold air passage 230. The cold air guided to thecold air passage 230 is supplied to the freezingcompartment 30 through thecold air outlet 412 formed on thebarrier cover 400. - In this case, a plurality of
cold outlets 412 is formed in a vertical direction, and the cold air is discharged evenly throughout the inside of the freezingcompartment 30 through thecold air outlets 412. The discharged cold air cools the inside of the freezingcompartment 30, and the cold air within the freezingcompartment 30 is again introduced through thecold air inlet 422 and is circulated while the blowingfan 134 is operated. - Furthermore, since the cold
air distribution device 140 provided in thecold air outlet 232 is in a closed state, the cold air is supplied only into the freezingcompartment 30 without being introduced into therefrigerating compartment 40. - Meanwhile, the
evaporator accommodating part 210, the blowingunit accommodating part 220 and thecold air passage 230 have been shielded by thebarrier cover 400 made of a relatively thin plastic material. Accordingly, cold air of theevaporator 110 or the cold air moving in the inside of thedepression part 200 may be heat-exchanged with the cold air of the freezingcompartment 30 due to heat conduction through thebarrier cover 400. - Describing a state in which cold air is supplied to the
refrigerating compartment 40 with reference toFIG. 8 , the blowingfan 134 is operated by the operation of themotor 132 in order to supply cold air to therefrigerating compartment 40. Due to the operation of the blowingfan 134, the cold air of the freezingcompartment 30 and therefrigerating compartment 40 introduced through thecold air inlets evaporator 110 to be more cold state, and is then moved upward according to the operation of the blowingfan 134. - The cold air moved upward from the
evaporator accommodating part 210 is moved into inside the blowingunit accommodating part 220 along thecoupling part 240, is then introduced into theorifice 137 of theshroud 136 by the guide of the coldair guide part 222. - The cold air introduced into the
shroud 136 is discharged into the outlet 139 of theshroud 136 to be guided to thecold air passage 230. The cold air guided to thecold air passage 230 is supplied to the freezingcompartment 30 through thecold air outlet 412 formed on thebarrier cover 400. Furthermore, the cold air guided through thecold air passage 230 is supplied up to the coldair distribution device 140 formed on the upper end of thecold air passage 230. The coldair distribution device 140 is opened when it is intended that the cold air is supplied to therefrigerating compartment 40. Accordingly, the cold air is discharged into thecold air outlet 232 through the coldair distribution device 140. - The cold air supplied into inside the refrigerating
compartment 40 through thecold air outlet 232 cools the inside of therefrigerating compartment 40, and the cold air of therefrigerating compartment 40 is again introduced through thecold air inlet 212 and is circulated while the blowingfan 134 is operated. -

motor 132 is fixed to thebarrier cover 400 by amotor mount 135, and arotating shaft 132 a is extended from themotor 132.

shroud 136 is fixed to thebarrier cover 400 in a form to accommodate the blowingfan 134. In addition, the edge of theorifice 137 formed in theshroud 136 is rounded toward the blowingfan 134 to be fitted to the inside of thebellmouth 134 c. Accordingly, the cold air moving to the coldair guide part 222 is softly guided into the blowingfan 134. Furthermore, as described above, the surface of theshroud 136 on which theorifice 137 is formed is spaced from the coldair guide part 222. As a result, the cold air moved from theevaporator accommodating part 210 is introduced into the blowingfan 134 in parallel to therotating shaft 132 a of the blowingfan 134 through theorifice 137. - By the structure as described above, the
barrier cover 400 may be integrated with theblowing unit 130. That is, when thebarrier cover 400 is separated, theblowing unit 130 can be separated along therewith. As a result, when the repair of theblowing unit 130 is required, product repair is easy by separating thebarrier cover 400. -

Furthermore, ablowing unit 130 which includes themotor 132, a blowingfan 134 and ashroud 136 is accommodated in the blowingunit accommodating part 220. - A different type of
heat insulator 500 from that of the foamedheat insulator 300 is provided in thedepression part 200. Theheat insulator 500 is for assisting the heat insulation of thedepression part 200 that is relatively thinner than other parts in thebarrier 100 and may be formed to have the shape of a thin sheet or plate. - The
heat insulator 500 is made of a material having a higher efficiency compared to the foamedheat insulator 300. For example, theheat insulator 500 may be implemented using a vacuum heat insulator (Vacuum Insulation Panel). - The vacuum heat insulator is formed such that a vacuum-packaged core is accommodated in the inside of an envelope having a low gas penetration rate, the heat insulation performance is considerably high whereas the thickness thereof is formed to be relatively thin, compared to the poly urethane or polystyrene.

third heat insulator 530 is relatively thicker than thecold air passage 230, the third heat insulator may be formed to be thinnest compared to thefirst heat insulator 510 and thesecond heat insulator 520. - As described above, the
heat insulator 500 may be formed to be divided into thefirst heat insulator 510, thesecond heat insulator 520 and thethird heat insulator 530. Furthermore, therespective heat insulators 500 are all attached to theevaporator accommodating part 210, the blowingunit accommodating part 200 and thecold air passage 230. - However, depending on the thickness of the
barrier 100, theheat insulator 500 may be attached only to any one of theevaporator accommodating part 210, the blowingunit accommodating part 220 and thecold air passage 230. In this case, theheat insulator 500 may formed to have a shape corresponding to a part to which theheat insulator 500 attached. - Furthermore, the

depression part 200 is shielded by thebarrier cover 400. Thebarrier cover 400 is formed to have a plate shape, and shields thedepression part 200 to form a part of the side surface of thebarrier 100, that is, a part of the wall of the inside of the freezingcompartment 30. Furthermore, thebarrier cover 400 is formed to have the same plane as the side surface of thebarrier 100 when being mounted on thebarrier 100. - The
barrier cover 400 may be formed of one plate material, and, if required, may be formed to be divided into a plurality of parts. In the case of division into the plurality of parts, thebarrier cover 400 may be formed to be divided into a part covering theevaporator accommodating part 210 and a part covering the blowingunit accommodating part 220 and thecold air passage 230. - In addition, the side surface of the
barrier 100 opposite to the surface on which thebarrier cover 400 is mounted is also formed to have a plane shape without protruding the outside, thereby forming a part of the wall of the inside of therefrigerating compartment 40. Accordingly, the both side surfaces of thebarrier 100 all may be formed to have a plane shape. - The rear surface of the
barrier cover 400 corresponding to theevaporator 110 may be contacted with theevaporator 110 to be pressed into theevaporator 110 to fix it, amount guide 424 having a shape corresponding to the evaporator may be formed to assist the fixation of theevaporator 110. - Furthermore, the plurality of

FIG. 19 is a perspective view of a barrier viewed from a refrigerating compartment according to a fourth embodiment of the present invention.FIG. 20 is a cross-sectional view taken along line 20-20′ ofFIG. 19 . - In the fourth embodiment of the present invention, same structures as the structures of the first embodiment as described above are denoted by the same reference numerals and therefore, the detailed description of the corresponding structures will be omitted.
- In the fourth embodiment of the present invention, a
condensation prevention part 600 for prevention of condensation is formed in a part of thebarrier 100 exposed to therefrigerating compartment 40. - Referring to
FIGS. 19 and 20 , the external shape of thebarrier 100 is defined by thecasing 150 which defines the internal spaces of therefrigerating compartment 40 and the freezingcompartment 30. Theheat insulator 300 is formed by filling foaming liquid into the inside of thecasing 150. - Meanwhile, the
depression part 200 that is depressed in the freezingcompartment 30 is formed in thebarrier 100. Thedepression part 200 is formed to be depressed on the one side surface of thebarrier 100 and is formed to be opened toward the freezingcompartment 30. Thedepression part 200 may be configured to include anevaporator accommodating part 210 in which theevaporator 110 for generation of cold air is accommodated, a blowingunit accommodating part 220 which accommodates theblowing unit 130 for circulation of cold air, and acold air passage 230 which supplies the cold air generated by theevaporator 110 to therefrigerating compartment 40 and the freezingcompartment 30. - A cold air inlet is formed in the lower part of the
barrier 100 for therefrigerating compartment 40 and a cold air outlet is formed in the upper part thereof. Furthermore, aninlet grill 214 and anoutlet grill 234 are provided respectively at the cold air inlet and the cold air outlet, and the inside of thebarrier 100 in which the refrigeratingcornpartment 40 and the inside of barrier in which theevaporator 110 are in communication with each other, thereby allowing supply of cold air. - A
cover inlet 422 is formed in the lower part of thebarrier 100 for the freezingcompartment 30 and acover outlet 412 is formed in the upper part thereof. Therefore, the inside of thebarrier 100 in which the freezingcompartment 30 is provided and the inside of thebarrier 100 in which theevaporator 110 is provided are in communication with each other thereby allowing supply of cold air. - Meanwhile, the
blowing unit 130 which is configured to include themotor 132, the blowingfan 134 and theshroud 136 is accommodated in the blowingunit accommodating part 220. Furthermore, the blowingunit accommodating part 220 is formed to be depressed greater than theevaporator accommodating part 210 and thecold air passage 230. - In order words, since the blowing
unit accommodating part 220 is relatively depressed greater than theevaporator accommodating part 210, the thickness of theheat insulator 300 corresponding to theevaporator accommodating part 210 relatively becomes thinner. Accordingly, it is possible to secure a smooth flowing passage of cold air upon mounting of theblowing unit 130. Furthermore, the thickness of theheat insulator 300 corresponding to the blowingunit accommodating part 220 is relatively thin, but the heat insulation of theblowing unit 130 having a temperature relatively higher than that of theevaporator 110 is sufficiently possible. - Meanwhile, the
depression part 200 is shielded by thebarrier cover 400. Thebarrier cover 400 is formed to have a plate shape, and shields thedepression part 200 to form a part of the side surface of thebarrier 100, that is, a part of the wall of the inside of the freezingcompartment 30. Furthermore, the fixation of theevaporator 110 and the formation of the cold air passage are possible by the mounting of thebarrier cover 400. - In addition, the side surface of the
barrier 100 opposite to the surface on which thebarrier cover 400 is mounted is also formed to have a plane shape without protruding into the outside, thereby forming a part of the wall of the inside of therefrigerating compartment 40. Accordingly, the both side surfaces of thebarrier 100 all may be formed to have a plane shape. - Meanwhile, the
condensation prevention part 600 to prevent condensation from occurring on the surface of thebarrier 100 may be formed in the side surface of the barrier which defines the side surface of the refrigerating compartment. - The
condensation prevention part 600 will be described in detail below with reference to the drawings. -
FIG. 21 is a partial plan view enlarging a condensation prevention part according to an embodiment. - Referring to
FIG. 21 , thecondensation prevention part 600 is formed in thebarrier 100 which defines the side surface of therefrigerating compartment 40. Thecondensation prevention part 600 may be formed to include a plurality of grooves which is formed to be depressed and may be formed in a location corresponding to the blowingunit accommodating part 220. - Specifically, the
condensation prevention part 600 may be configured to includepartition parts 601 continuously protruding at uniform intervals in horizontal and vertical directions and heat insulatinggrooves 602 defined by thepartition parts 601. Accordingly, theheat insulating grooves 602 are formed to have a groove shape having a rectangular cross section Thecondensation prevention part 600 may be configured such that theheat insulating grooves 602 are arranged continuously in a grid shape in horizontal and vertical directions. - Furthermore, the
condensation prevention part 600 may be formed in thecasing 150 which defines thebarrier 100. That is, thecondensation prevention part 600 may be formed by a plurality ofheat insulating grooves 602 which is depressed in thecasing 150. Furthermore, thecondensation prevention part 600 may be formed by a plurality ofpartition parts 601 which protrudes the surface of thecasing 150. - The
condensation prevention part 600 may be formed in a location corresponding to the blowingunit accommodating part 220 at which the thickness of theheat insulator 300 is relatively thin on thebarrier 100. The location corresponding to the blowingunit accommodating part 220, at which the thickness of theheat insulator 300 is thin, is adjacent to the inside of therefrigerating compartment 40 and, therefore, may be a portion at which a possibility that condensation occurs is high. - Meanwhile, the
heat insulating grooves 602 are formed such that a ratio of the width and depth of theirs opened inlets is about less than 6:1. That is, when the ratio of the width and depth of inlets is too large, re-circulation of air in the inside of theheat insulating grooves 602 may not occur, so that theheat insulating grooves 602 may be formed in a size to allow re-circulation of air to occur in the inside of theheat insulating grooves 602. - For example, the horizontal and vertical widths of the inlet of the
heat insulating groove 602 may be set to about 5 mm, and the depth of theheat insulating groove 602, that is, the height of thepartition part 601 is set to about 2.5 mm. In this case, the ratio of the width and depth of the inlet of theheat insulating groove 602 is about 2:1, and re-circulation of air can occur in the inside of theheat insulating grooves 602. - The height of the
partition part 601 may be variously set, but, when it is set to about more than 10 mm, not only the appearance thereof is not good, but also storage of foods in the refrigerator may be also influenced. Accordingly, the height of thepartition part 601 is appropriately set to about less than 10 mm and, when the size of the inlet of theheat insulating groove 602 is considered, may be set to more than 1 mm. - Meanwhile, the
condensation prevention part 600 may be formed in various groove shapes and the inlet of theheat insulating groove 602 may be formed in various shapes, such as polygon, circle, oval shapes or the like which allow re-circulation of air to occur in addition to a rectangular shape. -
FIG. 22 is a diagram showing the flow state of cold air within the barrier viewed from the refrigerating compartment. - Referring to the drawing, cold air is generated by the operation of the freezing cycle in the
evaporator 110. - In order for supply of the cold air into the
refrigerating compartment 40 and the freezingcompartment 30, the blowingfan 134 is operated by the operation of themotor 132. Due to the operation of the blowingfan 134, the cold air of the freezingcompartment 30 and therefrigerating compartment 40 introduced through thecover inlet 422 and the cold air inlet is heat-exchanged by theevaporator 110 to be more cold state, and is then moved upward according to the operation of the blowingfan 134. - The cold air moving upward from the
evaporator accommodating part 210 is moved into inside the blowingunit accommodating part 220 along thecoupling part 240, is then introduced into the orifice of theshroud 136 by the guide of the cold air guide part. - The cold air introduced into the
shroud 136 is discharged into the outlet of theshroud 136 to be guided to thecold air passage 230. The cold air guided to thecold air passage 230 is supplied to the freezingcompartment 30 through thecover outlet 412 formed on thebarrier cover 400. - In this case, a plurality of
cover outlets 412 is formed in a vertical direction, and the cold air is discharged evenly throughout the inside of the freezingcompartment 30 through thecover outlets 412. The discharged cold air cools the inside of the freezingcompartment 30, and the cold air within the freezingcompartment 30 is again introduced through thecover inlet 422 and is circulated while the blowingfan 134 is operated. - Furthermore, the cold air guided through the
cold air passage 230 is supplied up to the coldair distribution device 140 on the upper end of thecold air passage 230. The coldair distribution device 140 is opened when it is intended that the cold air is supplied to therefrigerating compartment 40. Accordingly, the cold air is discharged into the cold air outlet and theoutlet grill 234 through the coldair distribution device 140. - The cold air supplied into inside the refrigerating
compartment 40 through theoutlet grill 234 cools the inside of therefrigerating compartment 40, and the cold air of therefrigerating compartment 40 is again introduced through the cold air inlet and thegrill inlet 214 and is circulated while the blowing fan is operated. -
FIG. 23 is a diagram showing simulation for air flow of the condensation prevention part. Furthermore,FIG. 24 is a diagram showing simulation for heat distribution of the condensation prevention part. - Referring to
FIGS. 23 and 24 , the cold air discharged from theoutlet grill 234 is introduced into theinlet grill 214 in therefrigerating compartment 40 to be circulated in the inside of therefrigerating compartment 40. - Some of cold air that is circulated in the inside of the
refrigerating compartment 40 is moved along the wall surface of thebarrier 100. In this case, the cold air moving along thebarrier 100 is separated from thecondensation prevention part 600. - Specifically, the air passing through the
condensation prevention part 600 is separated from the inlet of theheat insulating groove 602 of thecondensation prevention part 600, and a part thereof is moved into the inside of theheat insulating groove 602. As described above, some of cold air separated from the inlet of theheat insulating groove 602 moves in a direction of progress and passes theheat insulating groove 602 by, and the rest thereof is introduced into the inside of theheat insulating groove 602. - The cold air introduced into the inside of the
heat insulating groove 602 is moved along the wall surface of the inside of theheat insulating groove 602. That is, the cold air is moved from the inlet of theheat insulating groove 602 sequentially into the side wall, bottom and opposite side wall thereof. - Furthermore, when the cold air that is moved in the inside of the
heat insulator groove 602 again reaches the inlet of theheat insulating groove 602, the cold air is prevented from being moved out thereof by the cold air passing theheat insulating groove 602 by, and is then moved into the inside of theheat insulating groove 602, thereby being circulated in the inside of theheat insulating groove 602. - As described above, re-circulation of the introduced cold air occurs in the inside of the
heat insulating groove 602. Accordingly, an air layer is formed at the depth of theheat insulating groove 602 in thecondensation prevention part 600. Furthermore, re-circulation of the cold air occurs in the insides of all of the plurality ofheat insulating groove 602 formed in thecondensation prevention part 600, so that a heat insulating layer to block heat-exchange is formed in thecondensation prevention part 600. - Specifically, an air layer is formed between the surface of the
barrier 100 and the inside of therefrigerating compartment 40 by the cold air which is re-circulated in theheat insulating grooves 602. Furthermore, the air within therefrigerating compartment 40 is not directly heat-exchanged with the surface of thebarrier 100 by the air layer. - That is, the heat delivery rate of the surface of the
barrier 100 is lowered by preventing the mixing between the surface temperature of thebather 100 and the air of the inside of therefrigerating compartment 40. Accordingly, condensation does not occur in the surface of thebarrier 100 even in the location corresponding to the blowingunit accommodating part 220 at which the thickness of theheat insulator 300 is relatively thin. - Meanwhile, the condensation prevention part may be formed at various locations in addition to the above-described location.
