Here, the refrigerant in the cooler 18 evaporates, and cool air for cooling each storage chamber is generated in the cooling chamber 16 having the cooler 18.

  Next, the cooling operation by the cold air circulation will be described.

  The low-temperature cold air generated in the cooling chamber 16 is sent by the cooling fan 19 from the cooling chamber cold-air conveyance path 30 to the refrigerator compartment 7 and the freezer compartment 9, and the cold air supplied to the refrigerator compartment 7 cools the refrigerator compartment 7. After that, it is supplied to the vegetable room 8 and each room is cooled to the set temperature. Then, the cold air after cooling each chamber returns to the cooling chamber 16 again, is cooled by the cooler 18, and is circulated to each chamber by the cooling fan 19. In addition, the cold air supply to each of the chambers is performed by the control unit 81 operating / stopping the compressor 15 and the cooling fan 19 based on the temperatures detected by the refrigerator temperature detecting means 78 and the freezer temperature detecting means 80, and the refrigerator compartment damper 31. The freezer damper 34 is controlled to open and close so that each chamber is maintained in a set temperature range.

  Next, the cooling operation of the vegetable compartment 8 will be described.

  The vegetable room 8 is cooled by the cold air after cooling from the refrigerated cold air return passage 33 being supplied from the vegetable cold air inlet 44 provided in the cold air return passage 38 as shown in FIG. The cold air gently flows into the vegetable room 8 from the vegetable cold air inlet 44 through the vegetable room passage portion 50 by the blowing pressure of the cooling fan 19, and the lower container 57 and the upper container 58 of the vegetable room container 55 and the inner peripheral wall of the vegetable room 8. The vegetables, plastic bottles, etc. stored in the vegetable compartment container 55 are indirectly cooled from the outer periphery of the container, and cool air is supplied from the vegetable cold air return port 46 via the refrigerated cold air return passage 33. It circulates from the return duct 40 to the cooling chamber 16.

  Here, in the refrigerator shown in this embodiment, as shown in FIG. 11, the vegetable room fan 53 is provided in the vegetable room passage portion 50 of the vegetable room 8, and when the vegetable room fan 53 rotates, the return passage 38 is opened. Most of the returned cold air flowing is sucked from the vegetable cold air inlet 44 into the vegetable room passage section 50 and supplied from the outlet 54 of the vegetable room fan 53 toward the rear surface of the lower container 57 in the vegetable room 8. .

  The cold air supplied toward the lower container 57 of the vegetable compartment 8 is circulated by the air pressure of the cooling fan 19 in the space between the lower container 57 and the upper container 58 and the bottom and inner peripheral walls of the vegetable compartment 8. It flows faster than the flow and returns to the cooling chamber 16 from the vegetable cold air return port 46 via the return passage 38 and circulates. At that time, cool air other than the cool air returning to the cooling chamber 16 is circulated from the first vegetable cold air inlet 47 and the second vegetable cold air inlet 51 provided in the upper portion of the vegetable chamber 8. Is sucked into the vegetable compartment fan 53 from the upper opening of the vegetable compartment passage portion 50 communicating with these passages 51a, and again from the air outlet 54 of the vegetable compartment fan 53 to the lower container in the vegetable compartment 8 again. It is supplied toward 57 and diffuses or circulates in the vegetable compartment 8.

  First, in the vegetable compartment container 55 of the refrigerator, a lower container 57 is divided into a vegetable storage part 61 and a non-vegetable storage part 60 by a partition plate 59, and an upper container 58 is placed on the upper opening of the vegetable storage part 61. Since the three storage units are configured, food is divided into the respective storage units, for example, fruits are stored in the upper container 58, vegetables are stored in the vegetable storage unit 61, and plastic bottles are stored in the non-vegetable storage unit 60. Drinks such as packs can be stored efficiently.

  Moreover, since the said vegetable compartment container 55 equips the partition plate 59 which forms the vegetable storage part 61 with the moisture permeable membrane unit 62, it can maintain the humidity in the vegetable storage part 61 substantially constant, Can be cooled and stored in good condition. That is, the inside of the vegetable storage unit 61 is in a high humidity state due to moisture transpiration from the vegetables stored in the vegetable storage unit 61. However, when the humidity is higher than a predetermined humidity, for example, higher than the saturation humidity, the humidity component is indicated by a broken line arrow in FIG. Through the moisture permeable membrane 62-2 provided on the partition plate 59, the moisture is gradually permeated into the non-vegetable storage unit 60, and the inside of the vegetable storage unit 61 has a humidity of 80 to 95% R.D. H. To be kept.

  Here, since the moisture permeable membrane 62-2 is located between the vegetable storage unit 61 and the non-vegetable storage unit 60 in the vegetable compartment container, vegetables or the like may be placed on the top and be damaged. Disappear. Moreover, since the partition plate 59 to which the moisture permeable membrane 62-2 is attached is not a box-like member like the vegetable compartment container 55 but is a plate-like member and has a small size, the opening 59-1 for attaching the moisture permeable membrane is provided in the partition plate. There is no need to reduce the productivity due to the integral molding at the time of molding.

  In this embodiment, as described above, the vegetable compartment container 55 is composed of a lower container 57 and an upper container 58 placed on the upper part of the vegetable container so as to be slidable back and forth. The upper part of the vegetable storage unit 61 can be reasonably covered using the upper container 58, and the humidity can be prevented while preventing the cold air from entering the vegetable storage unit 61. Can be maintained in a substantially constant state, and the vegetables can be well preserved by cooling.

  Further, since the moisture permeable membrane 62-2 is integrally formed with the resin frame 62-1, and is attached to the partition plate 59 as the moisture permeable membrane unit 62, the moisture permeable membrane itself can be easily attached to the partition plate 59. .

  Further, the partition plate 59 is fitted with recesses 57a formed at the upper end of the outer peripheral wall of the lower container 57 with the hanging piece portions 59-3a and 58-3b formed at both ends thereof, and the mounting piece portions 59-2a and 59-. Since 2b is placed on the upper end of the outer peripheral wall of the lower container 57 and attached to the lower container 57, the partition plate 59 can be attached simply by being fitted into the lower container from the upper opening of the lower container 57. Moreover, the partition plate 59 is fixed by being positioned in the left-right direction by fitting the hanging pieces 59-3a and 58-3b into the recesses 57a, and the partition plate 59 moves carelessly in the lower container. The volume of the storage unit 61 or the non-vegetable storage unit 60 changes, or a plastic bottle or the like stored in the non-vegetable storage unit 60 moves each time the door is opened and closed, pushing the partition plate 59 toward the vegetable storage unit 61 and vegetables. It is possible to prevent the pressure from being deteriorated. Further, since the partition plate 59 can be removed, there is an advantage that the moisture permeable membrane unit 62 can be easily cleaned and maintained.

  As described above, this refrigerator is provided with the moisture permeable membrane 62-2 without causing damage to the moisture permeable membrane or lowering the productivity, so that the humidity of the vegetable storage unit 61 can be maintained substantially constant. Although the refrigerator can be stored in a refrigerator, the upper container 58 constituting the vegetable compartment container 55 can be slid lightly and at the same time, the lower container 57 and the upper container 58 are brought into close contact with each other without any gap. This can prevent the intrusion of cold air into the lower container, and this point will be further described.

  That is, when the upper container 58 of the vegetable compartment container 55 slides back and forth on the lower container 57, the protrusion 68 provided on the upper container rail 63 is a straight line of the lower container rail 64 as shown in FIG. The straight portion 67 of the upper container rail portion 63 contacts the intersection portion 71 of the lower container rail portion 64 and is supported at these two points, and slides on the lower container rail portion 64 of the lower container 57. Therefore, the upper container 58 can accommodate a large amount of fruit and can be slid lightly even if it is heavy.

  When the vegetable compartment container 55 is stored in the vegetable compartment 8 with the door 11 closed, the protrusion 68 of the upper container rail portion 63 enters the concave portion 72 of the lower container rail portion 64 to enter the upper container rail portion 63. The straight portion 67 and the straight portion 69 of the lower container rail portion 64 are in contact with each other, and the contact portions of these both come into close contact with no gap. Therefore, the cold air flowing around the vegetable compartment container 55 can be prevented from entering the vegetable storage part 61 of the lower container 57 from between the lower container 57 and the upper container 58, and is stored in the vegetable storage part 61. The vegetables can be stored in a cool state without being deteriorated by drying.

  Moreover, since this refrigerator has various effects also about vegetable room cooling, this is also demonstrated below.

  First, in this embodiment, a vegetable room fan 53 is provided in the vegetable room 8, and this vegetable room fan 53 is provided on the back part of the vegetable room on the non-vegetable storage part 60 side of the vegetable room container 55. The cool air in the vegetable compartment is diffused or circulated toward the vegetable storage section 60. Therefore, the cold air from the vegetable compartment fan 53 circulates intensively around the non-vegetable storage unit 60, and the plastic bottles and packs stored in the non-vegetable storage unit 60 can be efficiently cooled. . In particular, drinking water such as PET bottles and packs stored in the non-vegetable storage unit 60 is effective because it has a larger heat capacity than vegetables and is difficult to cool, thereby increasing the temperature of the vegetable room due to storage of PET bottles and the like. Can be efficiently suppressed.

  Further, since the first vegetable cold air inlet 47 provided in the vegetable chamber 8 together with the vegetable chamber fan 53 is provided in the front portion of the vegetable chamber container 55 on the non-vegetable storage portion 60 side, The cold air to the vegetable cold air return port 46 can be circulated more efficiently and intensively to the non-vegetable storage portion, which is effective.

  Further, the second vegetable cold air suction port 51 serving as another suction port for circulating the cold air in the vegetable chamber 8 is provided at the upper portion of the vegetable chamber substantially diagonally with the vegetable chamber fan 53. Therefore, the cold air from the vegetable compartment fan 53 diffuses and circulates through the bottom portion of the non-vegetable storage portion 60 of the vegetable compartment container 55 forward and diagonally through the vegetable compartment 8, and then circulates in the upper part of the vegetable compartment. The second vegetable cold air inlet 51 flows, so that cold air is diffused over the outer circumference of the vegetable chamber container 55 while preventing the cold air from entering the vegetable chamber container consisting of the lower container 57 and the upper container 58. And can be circulated to effectively cool vegetables, plastic bottles, and the like.

  Further, in this refrigerator, a communication passage 39 is formed between the refrigerated cold air return passage 32 and the refrigerated cold air return passage 33, and when the vegetable compartment fan 53 rotates, the suction force of the vegetable compartment fan 53 causes the low temperature in the refrigerated cold air passage 32 Fresh cold air is mixed into the refrigerated cold air return passage 33 and supplied from the vegetable cold air inlet 44 into the vegetable compartment 8 through the return passage 38. Therefore, in this refrigerator, the vegetable compartment 8 is cooled by the low-temperature cold air by mixing the low-temperature fresh cold air into the cold air after cooling the refrigerator compartment by the rotation of the vegetable compartment fan 53. Therefore, the vegetable compartment 8 can be effectively cooled, and the vegetable compartment 8 is reliably cooled even when the cooling load condition is bad, for example, when many vegetables, plastic bottles, etc. are temporarily stored. be able to. In addition, the amount of low-temperature fresh cold air taken in through the communication passage 39 can be increased by increasing the number of rotations of the vegetable compartment fan 53, and a large amount of room temperature PET bottles having a large heat capacity are stored in summer. Even at times, this can be reliably cooled. Moreover, since the vegetable compartment 8 can be reliably cooled, the occurrence of dew condensation due to cold radiation from the cooling compartment 16 can be efficiently suppressed, and the vegetables can be stored in a cooled state in a good state.

  The vegetable compartment fan 53 operates when the refrigerator compartment damper 31 is opened by the output from the refrigerator compartment temperature detecting means 78 to cool the refrigerator compartment 7 and the vegetable compartment 8 and diffuses the cold air in the vegetable compartment 8 or Although it circulates, in this embodiment, since it controls also based on the detection temperature of the vegetable compartment temperature detection means 79 provided in the vegetable compartment 8, the temperature of the refrigerator compartment 7 is high, and cooling operation is not performed. Even when the temperature of the vegetable compartment 8 becomes equal to or higher than the set temperature, the vegetable compartment 8 starts to rotate and diffuses and / or circulates cold air in the vegetable compartment 8. Therefore, when the temperature of the vegetable room becomes high and a large temperature difference is caused by the cold radiation from the cooling chamber 16 and the condition is likely to cause dew condensation, the vegetable room fan 53 rotates to eliminate this and effectively generate dew condensation. Can be prevented.

If the temperature of the vegetable room 8 becomes higher than the second set temperature set to a temperature slightly higher than the set temperature in spite of the rotation of the vegetable room fan 53, the vegetable room fan The number of rotations of 53 can be increased to increase the diffusion or circulation of the cold air, and the amount of fresh cold air taken in can be increased and the vegetable room 8 can be reliably cooled. Therefore, the lack of cooling in the summer can be resolved, and good cooling storage of vegetables and the like can be reliably realized to increase the reliability of the refrigerator.

  Although the embodiment of the present invention has been described above, the configuration described in the above embodiment is shown as an example for carrying out the present invention, and various modifications can be made within the scope of achieving the object of the present invention. Needless to say.

  For example, although the moisture permeable film 62-2 illustrated what laminated | stacked the silicon thin film and the hydrophilic nylon fiber, it was not restricted to this, and when the humidity in a vegetable storage part becomes more than predetermined value, the humidity component Any material can be used as long as it allows moisture to be maintained at a constant humidity.

  The refrigerator according to the present invention can maintain a substantially constant humidity in the vegetable storage section by providing the vegetable compartment container with a moisture permeable membrane without damaging the moisture permeable membrane or reducing productivity, and cooling vegetables in a good state. Can be saved. Therefore, it can be widely applied to refrigerators for business use as well as home use.
