Description: BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a refrigerator, and more particularly a refrigerated air supply apparatus for providing a portion of refrigerated air rearward from the door of the refrigerator. 2. Description of Background Art As shown in Figs. 1 and 2, generally refrigerators have a freezer compartment 10 and a fresh food compartment 20 partitioned by an insulation barrier 5. The compartments 10, 20 are defined by inner cases 12, 22 respectively surrounded by insulation 7 which is cased by outer case 2. And a fan unit 4 which is for providing refrigerated air flow path to both freezer compartment 10 and fresh food compartment 20 is mounted in an evaporating chamber 11 provided at the rear of the freezer compartment 10. An evaporator 8 is also provided in the evaporating chamber 11 in which refrigerated air is generated thereby. The compartments 10, 20 are closed by doors 19, 29 which are hinged in front of the refrigerator. And the door 29 has door baskets 26 mounted at inner surfaces thereof for storing food therein. Conventional refrigerated air circulation will be explained in view of Figs. 1 and 2. As refrigeration cycle drives, refrigerated air is generated by the evaporator 8 in which working fluid or refrigerant flows. And as the fan unit 4 drives, a portion of the refrigerated air flows to the freezer compartment 10, and the other portion of the refrigerated air impinges on a grill 16 and is then guided to fresh food duct 24 through a passage 15 defined by a shroud 14 and a grill 16. The refrigerated air guided to the fresh food duct 24 is then blown out into the fresh food compartment 20 through a plurality of outlets 25 formed in the front surface thereof. Refrigerated air supplied to fresh food compartment 20 via the above-mentioned supply path, then moves forward and carries out heat exchanges with food stored in fresh food compartment 20, thereby becoming relatively warm air. The warm air returns to the evaporating chamber 11 through a return duct 30 formed in the insulation barrier 5 with its inlet 31 adjacent to the door 29. And the warm air in the evaporating chamber 11 carries out heat exchanges with the evaporator 8, thereby becoming refrigerated air repeatedly. But the conventional refrigerated air circulation system has a number of shortcomings. First, it reduces the effective uniform cooling of the fresh food compartment 20, since the refrigerated air is provided only in one direction, forward, from the outlets 25 of fresh food duct 24. This means that the temperature of a portion adjacent to the outlets 25 is lower than that of a portion adjacent to the door 29. Therefore, food stored adjacent to the outlets 25 may be over-refrigerated while food stored adjacent to the door 29 is tend to be perishable due to relative high temperature. This problem is based on the fact that the refrigerated air is provided into the fresh food compartment 20 only in one direction from the duct 24. Second, the temperature of a door adjacent portion in the fresh food compartment 20 tends to be increased due to frequent opening of the door 29. It takes relatively longer time to decrease the temperature of the door-adjacent portion than that of the portion adjacent to the fresh food duct 24, since refrigerated air is only provided by the fresh food duct 24. Third, it is difficult to keep the food stored in the door baskets 26 to the temperature desired, due to a inflow of warm air from outside when the door is opened. An improved refrigerated air circulation system was described in U. S. Pat. No. 5,584,191 issued Dec. 17, 1996. According to the air circulation system, refrigerated air is blown out into fresh food compartment by either cool air duct mounted at the corner of fresh food compartment and door duct into which the refrigerated air is provided simultaneously by a transmission duct mounted on a side wall. The transmission duct is exposed to the interior of fresh food compartment and it only delivers refrigerated air which has been spouted in fresh food compartment through the cool air duct to the door duct. The air circulation system has still some problems although it improves uniform refrigerating effect by the spouted refrigerated air from the door duct. A problem with the circulation system is that the transmission duct occupies a certain space in the fresh food compartment where food is stored so that the substantial storage space in fresh food compartment is restricted by the presence of the transmission duct. Another problem is that the amount of refrigerated air spouted by the door duct is not sufficient, since the refrigerated air delivered through the transmission duct is the one which had been provided to the cool air duct. This problem can be overcome by a circulation system which delivers refrigerated air from the evaporating chamber directly to the door duct, without via the cool air duct. Still another problem is that the temperature difference between the fresh food compartment and interior of the transmission duct conduce to dewing and freezing on the surface of the transmission duct. A refrigerator according to the preamble of claim 1 is known for example from US-A-5 285 655. SUMMARY OF THE INVENTION It is an object of the invention to provide an improved refrigerator that provides refrigerated air uniformly in the fresh food compartment. It is another object of the invention to provide prompt cooling of a portion adjacent to the door. It is still another object of the invention to provide an improved air refrigerator that provides sufficient refrigerated air to the door adjacent portion, to keep foods stored in the door baskets fresh. In accordance with the present invention, there is provided a refrigerator as defined in claim 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in Fig. 3 where the first embodiment of the invention is illustrated, a refrigerator of the invention has a freezer compartment 110 and a fresh food compartment 120 partitioned by an insulation barrier 134. A refrigerated air supply apparatus of the invention includes a connecting duct 132 which is diverged from a passageway 130 in the insulation barrier 134. The connecting duct 132 provides the refrigerated air to a door duct 160 mounted in a door 150 so that the door duct 160 flows refrigerated air into the fresh food compartment 120 rearward, thereby achieving uniform cooling of the fresh food compartment 120. The passageway 130 means a duct or a path which flows refrigerated air from a refrigerating chamber 111 to the fresh food compartment 120, including all conventional ones. In the embodiment shown in Fig. 3, the connecting duct 132 is diverged in the interior of the insulation barrier 134. Being diverged from the passageway 130 in the barrier 134, connecting duct 132 extends forward and has an outlet 133 on the front portion of lower wall 134a of the barrier 134. The outlet 133 of the connecting duct 132 is adjacent to the door 150 which closes the fresh food compartment 120. Since connecting duct 132 is mounted in the interior of the barrier 134, it does not occupy any space in the fresh food compartment 120. The storage space, therefore, in the fresh food compartment 120 can be fully utilized. As illustrated in Figs. 4 and 5, a door duct 160 is mounted in the door 150 which receives refrigerated air from the passageway 130 through the connecting duct 132. The door duct 160 has an inlet 161 which communicates with the outlet 133 of the connecting duct 132 and receives refrigerated air therefrom when door 150 is closed. In this embodiment, the inlet 161 is formed in the upper surface of the door liner 154, and refrigerated air provided via connecting duct 132 flows downward in the door duct 160. The door duct 160 has a vertical portion 162 which is communicated with the inlet 161 and a plurality of horizontal portions 164 which are communicated with the vertical portion 162. The horizontal portions 164 are provided with a plurality of outlet openings 166 respectively, to spout the refrigerated air into the fresh food compartment 120. Refrigerated air provided into the door duct 160 flows into the fresh food compartment 120 through the outlet openings 166 so that a door adjacent portion in the fresh food compartment 120 is chilled promptly which tends to be easily warmed due to the frequent opening of the door 150. In this embodiment illustrated, the horizontal portions 164 of the door duct 160 are positioned under door baskets 152. Refrigerated air spouted from the outlet openings 166 of the door duct 160 passes across the food stored in the door baskets 152, and then flows into the interior of the fresh food compartment 120. The food stored in the door baskets 152 is exposed to the spouted refrigerated air and is kept fresh thereby. Preferably, the door duct is formed integrally with the door baskets 152. And the outlet openings 166 may be formed in a manner that the refrigerated air flows rearward directly into the fresh food compartment 120 or in a manner that refrigerated air flows into the fresh food compartment 120 across the food stored in the door baskets 152. Also preferably the door duct 160 may be mounted in the interior of the door baskets 152. A refrigerated air supply path will be explained hereinafter with reference to the Figs. 3-5. A portion of refrigerated air generated by an evaporator 108 in refrigerating chamber 111 is directed to the freezer compartment 110 and the other is directed to the fresh food compartment 120 through the passageway 130 by a fan unit 104. Refrigerated air guided to the passageway 130 is then divided into two by the connecting duct 132. A portion of the divided refrigerated air is provided into a fresh food duct 124 mounted at the rear of the fresh food compartment 120, while the other is provided into the connecting duct 132. Refrigerated air in the fresh food duct 124 is spouted into the fresh food compartment 120 forward through a plurality of outlets 126 formed on the front surface thereof as indicated by arrows in Fig. 3. And refrigerated air in the connecting duct 132 flows forward to the outlet 133 thereof and then, flows into the door duct 160, inlet 161 of which is communicated with the outlet 133 in door-closed state. In the interior of the door duct 160, the refrigerated air flows downward along with the vertical portion 162 and is distributed to the horizontal portions 164. Then, refrigerated air is spouted into the fresh food compartment 120 rearward through outlet openings 166. It will be understood that refrigerated air is spouted into the fresh food compartment 120 forward by the fresh food duct 124 and rearward by the door duct 160 respectively. Interior of the fresh food compartment 120 is, therefore, charged with new refrigerated air uniformly Refrigerated air provided into the fresh food compartment 120, carries out heat exchanges with the foodstuff stored therein, then becoming relatively warm air. The warm air is returned to the evaporating chamber 111 where evaporator 108 is mounted through a return duct(not shown) and then becoming refrigerated air repeatedly by heat exchange with the evaporator 108. In the embodiment illustrated and explained, the connecting duct 132 is diverged from the passageway 130 in the insulation barrier 134. Substantially, the barrier is a partition defined by an inner wall 103b of freezer compartment 110 and an inner wall 103a of fresh food compartment 120 in which insulation material, such as urethane is filled. This means that the connecting duct 132 according to the invention does not occupy any space in the fresh food compartment so that inner space of the fresh food compartment 120 can be fully utilized for food storage. The second embodiment of the invention will be described hereinafter with reference to Figs. 6-8. According to the embodiment illustrated in Figs. 6 and 7, a connecting duct 232 is mounted in the interior of an insulation barrier 234 and a side wall 228 which is defined by an inner side wall 227 of a fresh food compartment 220 and an outer case 229. The connecting duct 232 is diverged from a passageway 230 which is a duct or a path for delivering refrigerated air to a fresh food duct 224 in the insulation barrier 234. Connecting duct 232 is then extended forward through the interior of the barrier 234 and the side wall 228 and has an outlet 233 formed on the front side surface of the side wall 228. It will be understood that being diverged from the passageway 230, the connecting duct 232 is extended forward through interior of the side wall 228 to the front side surface thereof. Substantially the side wall 228 defined by inner side wall 227 of fresh food compartment 220 and outer case 229 is filled with insulation material as known. Also in this embodiment, the connecting duct 232 does not occupy any storage space in fresh food compartment 220 by mounting it in the interior of the side wall 228. As shown in Fig. 8, a door duct 260 is mounted in the door 250. The inlet 261 formed on a side wall of the door 250 is communicated with the outlet 233 of the connecting duct 232 when the door is closed. And the door duct 260 is provided with a vertical portion 262 and a pair of horizontal portions 264 with a plurality of outlet openings 266. Substantially the function of the door duct 260 is the same one as described above except that it is provided with an inlet 261 in the side surface thereof. Refrigerated air generated by an evaporator 208 is distributed either to fresh food duct 224 and door duct 260 through the passageway 230 and connecting duct 232. Similarly, refrigerated air is spouted into the fresh food compartment 220 forward through a number of outlets 226 of the fresh food duct 224 and rearward through a number of outlet openings 266 of door duct 260, respectively. The interior of the fresh food compartment 220 is, therefore, charged with new refrigerated air uniformly. It will also be understood that the connecting duct 232 of the embodiment is mounted in the side wall 228 and barrier 234 in insulated state without occupying any storage space in fresh food compartment 220. Another embodiment for communicating connecting duct with door duct will be described with reference to Figs. 9 and 10. This embodiment discloses a connecting structure where refrigerated air in connecting duct will be delivered to door duct without leakage. As shown in Figs. 9 and 10, a connecting member 340 is mounted on the inclined front surface 329 of fresh food compartment 320. And an outlet 333 of connecting duct 332 is formed in the connecting member 340. A door duct 360 which has the same function and structure as explained above is mounted in the door 350. The door duct 360 is provided with an inlet 361 which is formed on the side surface of the door 350 to communicate with the outlet 333 of the connecting duct 332 when the door is closed. The connecting member 340 is protruded laterally toward the door 350 and is formed with resilient material to have close contact with the door 350 when closed. The connecting member 340 may be formed integrally with the inclined front surface 329 of the refrigerator. According to the embodiment, the connecting member 340 having outlet 333 of connecting duct 332 provides close contact with the side surface of the door 350 where inlet 361 of door duct 360 is formed. The refrigerated air which flows in the connecting duct 332 will be delivered to the door duct 360 without air leakage. It will be understood that the connecting member 340 can provide close contact between connecting duct 332 and door duct 360 to prevent air leakage. Therefore, various modifications can be occurred in its contour and design. Next, the third embodiment will be described with reference to Figs. 11 and 12. According to the embodiment, a connecting duct 432 is mounted along an inner side wall 428 of fresh food compartment 420. As described above and shown in Fig. 11, the connecting duct 432 is diverged from a passageway 430 in an insulation barrier 434 which is a duct or a path for guiding refrigerated air to a fresh food compartment 424. The inner side wall 402 is provided with a groove 460 as shown in Fig. 12 in which the connecting duct 432 is inserted. The groove 460 extends forward along the inner side wall 402. The connecting duct 432 is mounted in the groove 460 not to protrude inward in the fresh food compartment 420. The connecting duct 432 mounted in the groove 460 is surrounded by an insulation layer 464 which is cased by cover 462. And the connecting duct 432 is provided with its outlet 433 at the front surface of the side wall 428 which is communicated with an inlet of door duct(not shown) which is described and illustrated above. The connecting duct 432 is laid in the side wall 428 of the fresh food compartment 420 with surrounding insulation 464. In the producing process of this embodiment, an inner wall 402, an outer case 404 and an insulation 406 will be prepared as conventional except that the inner side wall 402 is provided with the groove 460. Therefore, the structure of the connecting duct 432 in this embodiment is easily applied to the conventional refrigerator. When the cabinet of refrigerator is prepared by a conventional manner, the connecting duct 432 having U section or pipe type section is assembled to the groove 460 of inner wall 402. Then assembling process will be finished by assembling insulation 464 and cover 462 on the connecting duct 432. It will be understood that according to the embodiment the connecting duct 432 also does not occupy any storage space in the fresh food compartment 420. And, the conventional problem inccurred by temperature difference between connecting duct 432 and fresh food compartment 420 will be overcome, since the connecting duct 432 is covered with insulation 464. And as stated above, this embodiment may be easily applied to the conventional refrigerators, since it does not require any further structural change except in the inner side wall 402. A refrigerator which is not in accordance with the invention will be described with reference to Figs. 13 and 14. Also in this example, the refrigerator is divided into a freezer compartment 510 and a fresh food compartment 520 by an insulation barrier 534. A fresh food duct 524 is mounted vertically at the rear wall of fresh food compartment 520 and provided with a plurality of outlet openings 526 to spout refrigerated air into the fresh food compartment 520. A refrigerating chamber 511 is provided at the rear of the freezer compartment 510 where an evaporator 508 and a fan unit 504 is mounted. Refrigerated air generated by the evaporator 508 is provided into the fresh food duct 524 through a passageway 530 mounted in the barrier 534. The passageway 530 is communicated with a duct or space 515 defined by a shroud 506 and a grill 507. A connecting duct 532 of this refrigerator is diverged at the uppermost portion of a fresh food duct 524 and mounted against the lower wall 534a of barrier 534. The connecting duct 532 extends forward along with the lower wall 534a and has an outlet 533 located in front of the fresh food compartment 520. A door duct 560 is mounted in the door 550 which closes the fresh food compartment 520. An inlet 561 of the door duct 560 is formed in the upper portion of the door 550 which communicates with the outlet 533 of connecting duct 532 when the door is closed, as shown in Fig. 14. Door duct 560 has a vertical portion 562 which is communicated with the inlet 561 and a pair of horizontal portions 564 which is communicated with the vertical portion 562. A plurality of outlet openings 566 are formed on the front surface of the horizontal portions 564. Refrigerated air flown into the door duct 560 through the connecting duct 532 is spouted into fresh food compartment 520 by the outlet openings 566, thereby cooling the door adjacent portion sufficiently in fresh food compartment 520. As described in the first embodiment, the outlet openings 566 of the door duct 560 are formed in a manner that refrigerated air spouted from the openings 566 passes through the food stored in the door baskets 552 respectively. Also similarly, the horizontal portions 564 may be formed integrally with the door baskets 552. And horizontal portions 564 may be mounted in the interior of the door baskets 552. In this example, the space occupied by the connecting duct 532 is not usually utilized as storage space, since the connecting duct 532 is diverged from the fresh food duct 524 at the uppermost portion there of and mounted along the lower wall 534a of barrier 534. Usually food is stored on the shelves mounted horizontally in fresh food compartment 520 so that the space occupied by connecting duct 532 is not necessarily required for food storage. The connecting duct 532 may be formed integrally with either fresh food duct 524 or lower wall 534a of the barrier. In that case, assembling process for connecting duct 532 will be very simple, thereby reducing additive process. With reference to Figs. 15 and 16, another embodiment for control of refrigerated air will be described. As shown in Figs. 15 and 16, a damper device 680 is installed at a point in which a connecting duct 632 is diverged from a passageway 630. The passageway 630 is a duct or path for guiding refrigerated air to the fresh food compartment 620 through a path or duct 640 and a fresh food duct 624. And the connecting duct 632 is a duct for delivering a portion of refrigerated air to the door duct described above. The damper device 680 controls amount of air flow to connecting duct 632 and to the path 640 respectively. Detailed description on internal structure of the damper device 680 is omitted herein, since the damper device 680 is known and there are various known damper devices which control amount of air flow in ducts. Refrigerated air generated by the evaporator(not shown) is guided into the passageway 630, and then flows into the path 640 and connecting duct 632, respectively. The damper device 680 is mounted in the passageway 630 where it is divided into path 640 and connecting duct 632, thereby controlling the amount of flow of refrigerated air respectively. In the embodiment, the damper device 680 is provided with a pair of baffle 682, 684 which open and close the path 640 and connecting duct 632. The damper device 680 illustrated schematically is a so called "twin damper" having a pair of baffles. The baffle 682 controls the amount of refrigerated air which flows into the fresh food compartment 620 through the path 640 and fresh food duct 624. And the baffle 684 controls the amount of refrigerated air which flows into the door duct through the connecting duct 632. It will be understood that each damper device can be mounted in either in passageway 640 and connecting duct 632, respectively. The damper device 680 is controlled by a micro processor(not shown) which is mounted in the refrigerator. Control of the baffle 684 in the damper device 680 which controls the amount of airflow of connecting duct 632 is carried out on the basis of a temperature sensed by a sensor 694 which is mounted in door adjacent portion. And control of the baffle 682 in the damper device 680 which controls the amount of airflow of passageway 640 is carried out on the basis of a temperature sensed by a sensor 692 mounted in the fresh food compartment 620. For example, when the temperature sensed by the sensor 694 is higher than desired, the micro processor controls the baffle 684 of the damper device 680 to be opened, thereby providing refrigerated air in the door adjacent portion. In case that a pair of separate damper devices is mounted in connecting duct 632 and passageway 640, respectively, the same control for the damper devices will be carried out on the basis of the temperatures respectively sensed by the sensors 692, 694. As illustrated and explained above, according to the air supply apparatus of the invention, refrigerated air is provided into the fresh food compartment by the fresh food duct and door duct respectively. This means that refrigerated air is spouted in the fresh food compartment forward and rearward simultaneously and this improves effective uniform cooling of the fresh food compartment. And the connecting duct which delivers refrigerated air to the door duct is mounted in the interior of insulation barrier or in the interior of the side wall of fresh food compartment. This provides sufficient storage space in the fresh food compartment by the fact that the connecting duct does not occupy any space in the food storage space, that is the fresh food compartment. And when connecting duct is mounted along with the lower wall of the barrier, the storage space is not so much limited than before, since the space occupied by the connecting duct is not so often utilized as storage space. Conventional problems such as dewing and freezing on the outer surface of the connecting duct can be overcome by mounting it in the interior of the barrier or in the interior of the side wall or at least mounting insulation layer on the connecting duct. Substantially the door adjacent portion tends to be easily warmed, due to the inflow of warm air when the door is opened. The apparatus of this invention provides refrigerated air concentratedly in the door adjacent portion by the door duct when the door is closed, thereby cooling the portion promptly. Accordingly, food stored in a door adjacent portion in the fresh food compartment will be kept fresh in spite of frequent opening of the door. Further, the food stored in the door basket which contacts relative warm air when the door is opened can be kept fresher by forming the outlet openings of the door duct in a position that refrigerated air spouted therefrom passes across the food stored in the door basket.
