  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing the refrigerator of the present embodiment. The refrigerator 1 includes a heat insulating box 2 that forms a main body, and the heat insulating box 2 is provided with a refrigerator compartment 3, a freezer compartment 4, and a vegetable compartment 5 in order from above. The refrigerator compartment 3 and the freezer compartment 4 are partitioned by a heat insulating wall 6, and the freezer compartment 4 and the vegetable compartment 5 are partitioned by a heat insulating wall 7.

  The refrigerator compartment 3 stores stored items in a refrigerator, and the front opening 3a is opened and closed by a pivotable door 3b. The freezer compartment 4 stores stored items in a frozen state, and the front opening 4 a is opened and closed by a drawer-type door 4 b formed integrally with the storage case 8. Guide portions (not shown) that extend back and forth and slide on each other are provided on the outer surfaces of the side walls of the freezer compartment 4 and the storage case 8. The storage case 8 is smoothly inserted and removed together with the door 4b by the guide portion.

  The vegetable room 5 stores stored items refrigerated at a refrigeration temperature higher than that of the refrigerated room 3, and stores vegetables and fruits. The front opening 5a of the vegetable compartment 5 is opened and closed by a drawer-type door 5b formed integrally with the storage case 10. Guide portions (not shown) that extend back and forth and slide on each other are provided on the outside of the side wall of the vegetable compartment 5 and the side wall of the storage case 10. The storage case 10 is smoothly put in and out with the door 5b by the guide portion.

  A compressor 41 is disposed behind the vegetable compartment 5. A condenser, an expander, and a cooler (all not shown) are connected to the compressor 41 in order, and a refrigerant such as isobutane is circulated by driving the compressor 41 to constitute a refrigeration cycle.

  2, 3, and 4 are a plan view, a perspective view, and a side sectional view of the storage case 10. FIG. 3 shows a state where the accessory case 11 is removed. The storage case 10 is formed of a resin molded product having an upper surface opened, and is attached to the back surface of the door 5b (see FIG. 1) filled with a heat insulating material. On the upper surface of the storage case 10 is placed a small case 11 for storing small items such as fruits. The accessory case 11 is made of a resin-formed product, and is slidable forward and backward with respect to the storage case 10. Thereby, the upper surface of the storage case 10 is opened and closed.

  A flexible packing 40 disposed between the small case 11 and the storage case 10 is provided. The packing 40 can be formed by using one or more of silicon rubber, nitrile rubber, ethylene propylene rubber, and chloroprene rubber. The packing 40 may be provided at the front end of the storage case 10. Thereby, when the upper surface of the storage case 10 is closed, the space between the storage case 10 and the accessory case 11 can be sealed at the front end. Further, the packing 40 may be provided at the rear end of the small case 11 to seal between the storage case 10 and the small case 11.

  A storage box 16 having an open top surface is disposed on the right side of the front portion of the storage case 10. A cutout portion 15 into which the storage box 16 is inserted is formed in the front portion of the accessory case 11, and the space between the accessory case 11 and the storage box 16 is sealed by the packing 40. In the storage box 16, a tall stored item such as a PET bottle having a capacity of 2L is stored.

  A minute vertical gap S1 is formed between the rear end of the storage case 10 and the accessory case 11. By providing the clearance S1, the sliding resistance when sliding between the storage case 10 and the accessory case 11 in the front-rear direction can be reduced.

  A rib 11b is provided at the rear end of the accessory case 11 so as to protrude downward facing the gap S1. Since the rib 11b covers the front surface of the gap S1, it is difficult for cold air to flow into the storage case 10. At this time, a gap S2 in the front-rear direction is formed between the back surface of the storage case 10 and the rib 11b. By providing the clearance S <b> 2, the front end of the storage case 10 can be reliably sealed by the accessory case 11.

  The storage case 10 is provided with an L-shaped partition plate 30 spaced from the rear surface of the storage case 10 by a distance d, for example, 3 mm to 5 mm. The front end 30 a of the partition plate 30 extends in the forward direction to the vicinity of the storage box 16, and the upper end 30 b extends upward to the vicinity of the accessory case 11. The partition plate 30 is detachable and is made of a metal such as aluminum. Thereby, while improving the convenience at the time of cleaning of the storage case 10, a stored item can be cooled efficiently.

  A plurality of adjustment ports 35 arranged in parallel in the left-right direction are provided on the back surface of the storage case 10. For this reason, the partition plate 30 is arranged so as to be separated from the adjustment ports 35 by the distance d and to cover the front surfaces of all the adjustment ports 35. The area of the adjustment port 35 is set to about 5 mm to 10 mm. A discharge port 36 for discharging cool air to the vegetable compartment 5 is provided behind the storage case 10.

  In the refrigerator 1 having the above-described configuration, cold air generated by heat exchange with the cooler is discharged to the refrigerating room 3 and the freezing room 4 to cool the refrigerating room 3 and the freezing room 4. The cold air flowing through the freezer compartment 4 returns to the cooler. The cold air flowing through the refrigerator compartment 3 is guided to the vegetable compartment 5 and discharged into the vegetable compartment 5 from the discharge port 36.

  Since the front portion of the storage case 10 is sealed, it is difficult for cold air to flow in from the adjustment port 35 due to the pressure of the storage case 10. At this time, even if cool air flows into the storage case 10 from the adjustment port 35, it is shielded by the partition plate 30 and flows out through the gaps S1 and S2. Thereby, the distribution | circulation of the cold air ahead of the partition plate 30 is suppressed, and the drying of a stored matter is suppressed.

  Further, when the pressure in the storage case 10 rises due to moisture released from the stored items in the storage case 10, cold air flows out from the adjustment port 35. Thereby, dew condensation in the storage case 10 can be prevented. At this time, the cold air flowing out from the adjustment port 35 merges with the cold air discharged from the discharge port 36 disposed behind the storage case 10 and flows around the storage case 10. Thereby, it is possible to suppress cold air containing a large amount of water from flowing again into the storage case 10 from the adjustment port 35.

  According to the present embodiment, the front end portion of the storage case 10 is sealed by the accessory case 11 and the front surface of the adjustment port 35 opened at the rear end portion is covered by the partition plate 30, so that it is stored by moisture released from the vegetable compartment 5. When the pressure in the case 10 rises, cold air flows out from the adjustment port 35. Thereby, dew condensation in the storage case 10 can be prevented. Moreover, since the cool air flowing in from the adjustment port 35 is blocked by the partition plate 30, it is possible to suppress the drying of the stored items.

  In addition, since the packing 40 disposed between the front end of the accessory case 11 and the storage case 10 is provided and the adjustment port 35 opens on the back surface of the storage case 10, the degree of sealing in the storage case 10 can be further increased. it can.

  Moreover, since the discharge port 36 which discharges cold air to the vegetable compartment 5 is provided in the back of the storage case 10, it can suppress that the cold air which contains a lot of moisture which came out of the adjustment port 35 flows into the storage case 10 again. it can.

  Moreover, since the notch 15 provided in the front part of the accessory case 11 is inserted into the storage box 16, the convenience in the storage case 10 can be improved without lowering the sealing degree in the storage case 10.

  Moreover, since the partition plate 30 consists of metals, such as aluminum, a stored item can be cooled more efficiently.

  In the present embodiment, in addition to the packing 40, a packing may be provided on the rib 11b to close the gap S2. However, a gap may be formed between the packing 40 and the front end of the storage case 10 when the packing of the ribs 11 b comes into contact with the back surface of the storage case 10 due to the assembly accuracy of the refrigerator 1. Accordingly, when the cool air flowing into the storage case 10 from the adjustment port 35 on the back flows through the storage case 10 toward the front gap, drying of the stored items is promoted.

For this reason, it is more desirable to arrange packing on either the front or back of the storage case 10. At this time, in the case where packing is provided on the rib 11b, the flow of the cold air in the storage case 10 can be suppressed by providing the adjustment port 35 on the front surface of the storage case 10.
