With the above configuration, the refrigerator compartment 3, the vegetable compartment 6, and the freezer compartment 8 are cooled to a predetermined temperature. The feature of the present invention is how efficiently this cold air circulation, in particular, the cold air circulation in the vegetable compartment 6 can be performed.

  As shown in FIG. 1, the vegetable storage container 5 forming the vegetable compartment 6 is made of a synthetic resin and is formed in a container shape having an upper surface opening, and ribs 16 projecting outward are formed on the outer surfaces of the left and right side walls 5a in the front-rear direction. The rib 16 is fitted into a recess (not shown) provided in the front-rear direction on the inner wall surface of the housing 1 so that the vegetable storage container 5 is inserted into the housing 1. Removably supported.

  As shown in FIG. 2, guide grooves 17 formed by intersecting a plurality of vertical grooves 17 a and horizontal grooves 17 b are provided on the inner surface side of the left and right side walls 5 a of the vegetable storage container 5. The guide groove 17 is slidably supported by engaging both ends of a later-described shelf plate 18. The groove width is about 1.5 cm wider than the thickness of the shelf board 18, but is not limited to this, and can be changed according to the thickness of the shelf board 18.

Two vertical grooves 17a are provided between the front and rear end portions of the left and right side walls 5a, and between them. The lateral groove 17b
Two are provided at the lower end and above. In addition, the number, length, and position of the vertical groove 17a and the horizontal groove 17b are not limited to the above-mentioned aspect, and can be freely designed according to how to partition the space in the vegetable compartment 6. For example, in FIG. 2, the length of the vertical groove 17 a is from the lower end of the left and right side walls 5 a to the middle of the upper side, but as shown in FIG. Also good. Further, as shown in FIG. 3, a vertical groove 17a and a horizontal groove 17b may be combined to form a step shape.

  As shown in FIG. 4, the shelf board 18 is configured by connecting a plurality of rectangular plate materials 18 a made of synthetic resin in the front-rear direction. A U-shaped handle 19 is provided at the front and rear ends of the shelf board 18a. If the handle 19 is pulled, it is possible to slide the guide groove 17 and easily change the position of the shelf board 18.

  Further, the shelf board 18 can be bent in the front-rear direction (length direction) as a whole of the shelf board 18 by connecting the respective plate members 18a so as to be rotatable. More specifically, as shown in FIGS. 4 to 6, the adjacent plate members 18 a are connected to each other at the left and right ends by a resin-made oval plate-like fastener 20 and a screw 21. Screw holes 22 are provided in advance at the left and right ends of the plate material 18a. Since the diameter of the screw hole 22 is larger than the diameter of the screw 21, the plate material 18 a can rotate with respect to the screw 21. Therefore, as shown in FIGS. 7 and 8, the angle between the fastener 20 and the plate member 18a is variable, and the bending is easy. For example, as shown in FIG. 9, the shape of the shelf board 18 can be changed at an arbitrary position.

The cold air can convect like white arrows. Due to this convection effect, the cool air is easy to circulate and the inside temperature can be kept uniform. Therefore, the deterioration of vegetables due to temperature fluctuations can be prevented. The size and shape of the vent hole 23 are not particularly limited as long as it allows ventilation.

  According to the above configuration, the vegetable compartment 6 can be partitioned by engaging both ends of the shelf board 18 with the guide groove 17 provided on the inner surface side of the left and right side walls 5 a of the vegetable storage container 5. By installing the shelf board 18 in the vegetable compartment 6, a space can be provided between the vegetables, and a structure in which cold air can easily circulate can be obtained. Keeps the temperature uniform and preserves vegetables for a long time with good freshness.

  Further, since the guide groove 17 is formed by intersecting the vertical groove 17a and the horizontal groove 17b, the shelf plate 18 is engaged with the vertical groove 17a to function as a partition wall in the vertical direction, or the guide groove 17 is engaged with the horizontal groove 17b. They can be combined to function as a partition wall in the horizontal direction. Further, since a plurality of vertical grooves 17a and horizontal grooves 17b are provided, the arrangement of the shelf boards 18 increases.

  Further, since the shelf board 18 has a structure that can be bent, the shelf board 18 is engaged with the longitudinal groove 17a and the lateral groove 17b, and is folded in several stages such as L-shape and U-shape. It can be bent and function as a partition wall in both vertical and horizontal directions. In this way, since the shelf boards can be provided in various forms, it is possible to partition various types of spaces with a single shelf board. Therefore, the storage chamber can be freely partitioned into shapes suitable for the type, size, and shape of the vegetables, and temperature unevenness can be prevented.

  Furthermore, since the shelf plate 18 formed by crossing the plurality of vertical grooves 17a and the horizontal grooves 17b can be freely slid along the guide grooves, the vertical direction engaged with the vertical grooves 17a. The partition wall can be switched to the partition wall in the lateral direction engaged with the lateral groove 17b, or vice versa, and further, the partition wall can be switched to the partition wall in the longitudinal direction and the lateral direction. Moreover, when the shelf board 18 is bent and provided, the length of the partition wall in the vertical direction or the partition wall in the horizontal direction can be freely adjusted by changing the position of the bend.

  Thus, since the direction and position which partition the inside of the vegetable compartment 6 can be selected freely, the vertical storage etc. suitable for the kind of vegetable can be selected, and a vegetable can be preserve | saved with sufficient freshness.

  For example, the case where the vegetable compartment 6 is partitioned into various shapes by the two shelf boards 18 will be described below with reference to FIGS. For convenience of explanation, it is assumed that one shelf board is 18b and the other shelf board is 18c.

  As shown in FIG. 10, if the shelf board 18b is installed as a partition wall in the vertical direction so that the upper side is open, vegetables suitable for vertical installation, such as radish, asparagus, burdock, etc., can be placed upright. Become. Since it can be brought close to the state in nature, vegetables can be stored with good freshness without consuming wasteful energy.

  Moreover, as shown in FIG. 11, if the shelf boards 18b and 18c are moved and installed as a partition wall in the horizontal direction, vegetables can be placed without being stacked, so that it is possible to prevent pain deterioration due to the weight of vegetables. it can. In addition, a space is created between the vegetables, and air can be moved by the ventilation holes 23 as indicated by the white arrows, so that temperature unevenness can be eliminated. Moreover, the length of the partition wall of a horizontal direction can be adjusted by bending the shelf boards 18b and 18c in several steps in L shape or U shape, and changing the position of the bending. A space for taking out the vegetables below is created on the side, making it easier to take out the vegetables. Thus, the space above the vegetable compartment 6 that was a dead space can be effectively utilized.

  As shown in FIG. 12, the shelf board 18 can be accommodated by moving the shelf boards 18b and 18c to the longitudinal groove 17a at the front and rear ends and the lateral groove 17b at the lower end. If there is no need to partition the vegetable compartment 6, it can be stored so that the shelf board 18 does not get in the way.

  As described above, even when a large variety of vegetables are stored in a large amount, a structure in which cold air can easily circulate is taken, the temperature is kept uniform, and the vegetables can be stored for a long time with good freshness. Moreover, the space of the vegetable room can be easily reconfigured according to the user's will in response to the change of vegetables.

  In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. For example, in the above embodiment, the guide groove 17 and the shelf board 18 are provided only in the vegetable compartment 6, but it is needless to say that the guide groove 17 and the shelf 18 may be provided in the refrigerator compartment 3 or the freezer compartment 8. Moreover, although the vegetable compartment 6 and the freezer compartment 8 were formed by the drawer-type storage containers 5 and 7, the inside of the housing | casing divided like the refrigerator compartment 3 is provided as it is, without providing a drawer container, as it is. It is good.
