The cold air supply port 16 constitutes a part of the cold air path, and in this case, is provided in the upper part of the rear wall portion of the vegetable compartment 13. Further, a damper 17 is provided in the cold air supply port 16. The damper 17 is rotatably provided, and the opening degree of the cool air supply port 16 is controlled by adjusting the amount of rotation. The amount of cold air supplied into the vegetable compartment 13 increases as the opening degree of the cold air supply port 16 by the damper 17 increases, and conversely, the amount of cold air supplied into the vegetable compartment 13 decreases as the opening degree of the cold air supply port 16 by the damper 17 decreases. The amount of cold air that is done is reduced.

  In addition, a vegetable case 18 formed of, for example, an opaque plastic material is provided inside the vegetable compartment 13. The vegetable case 18 is fixed to the back surface of a drawer-type vegetable room door 19 that opens and closes the vegetable room 13, so that the vegetable case 18 is taken in and out of the vegetable room 13 as the vegetable room door 19 is opened and closed. It has become.

  A partition wall 20 made of, for example, a transparent plastic material is provided inside the vegetable case 18. The partition wall 20 divides the interior of the vegetable case 18 into a plurality of storage units, in this case, a main storage unit 21 and a sub storage unit 22. The main housing portion 21 is a space formed on the rear side of the partition wall 20 and occupies most of the space including the rear portion of the vegetable case 18. The sub accommodating portion 22 is a space formed on the front side of the partition wall 20, that is, on the vegetable compartment door 19 side, and occupies a part of the vegetable case 18, in this case, the front portion. The volume of the main housing portion 21 is larger than the volume of the sub housing portion 22.

  A crisp case 30 made of, for example, a transparent plastic material is detachably attached to the top of the vegetable case 18. The crispa case 30 may be formed of the same plastic material as that of the partition wall 20 or may be formed of a different plastic material. In this case, the crispa case 30 is detachably mounted on the upper portion of the main housing portion 21 of the vegetable case 18 and is movable back and forth. The crispa case 30 functions as a thin bottom storage case smaller than the vegetable case 18, and also functions as an upper lid of the vegetable case 18, particularly the main storage portion 21.

  Moreover, the dimension of the front and rear direction of the chestnut case 30 is smaller than the dimension of the front and rear direction of the vegetable case 18. Thereby, in a state where the crispa case 30 is placed on the top of the vegetable case 18, the rear part of the vegetable case 18, in this case, above the rear part of the main housing part 21, is not opened by the crispa case 30. 31 is formed.

  The vegetable case 18 includes a moisture permeable sheet unit 32 at the opening 31. The moisture permeable sheet unit 32 is detachably attached to the opening portion 31.

The moisture permeable sheet unit 32 takes moisture into the inside from the outside of the vegetable case 18, and discharges moisture from the inside to the outside of the vegetable case 18, so that the inside of the vegetable case 18, particularly the main housing portion 21. Adjust the humidity.

  Next, a configuration example of the vegetable case 18 described above will be described in more detail. The inner surface of the vegetable case 18 constitutes the inner surface of the vegetable compartment 13 in the state accommodated in the vegetable compartment 13, that is, in the state where the vegetable compartment door 19 closes the vegetable compartment 13. A plurality of grooves 40 are provided on the inner surface of the vegetable case 18, in this case, at least on the inner surface of the bottom wall of the main housing portion 21, as illustrated in FIGS. 2 and 3. In this case, the groove part 40 extends linearly along the left-right direction of the refrigerator 10 on the inner surface of the bottom wall of the main housing part 21.

  As illustrated in FIG. 4, the groove portion 40 is formed by combining two types of inclined surfaces having different lengths, that is, a long inclined surface 41 and a short inclined surface 42. The long inclined surface 41 is an inclined surface having a predetermined length dimension, and forms a rear surface of the groove portion 40. The length dimension of the long inclined surface 41 can be appropriately changed and set. In addition, the normal direction of the long inclined surface 41 is directed upward of the front portion of the refrigerator 10. On the other hand, the short inclined surface 42 is an inclined surface having a length dimension shorter than that of the long inclined surface 41, and forms a front surface of the groove portion 40. The length dimension of the short inclined surface 42 can be appropriately changed and set in a range shorter than the long inclined surface 41. In addition, the normal direction of the short inclined surface 42 is directed upward in the rear part of the refrigerator 10. Therefore, the normal line of the long inclined surface 41 and the normal line of the short inclined surface 42 intersect with each other above the groove portion 40.

  The inclination angle of the long inclined surface 41 is gentle with respect to the horizontal plane, and is preferably set at least within an angle range of 45 ° from the horizontal plane. On the other hand, the inclination angle of the short inclined surface 42 is steep with respect to the horizontal plane, and is preferably set at least within an angle range of 45 ° to 90 ° from the horizontal plane.

  On the upper surface of the bottom wall of the main housing portion 21, the long inclined surface 41 and the short inclined surface 42 are alternately arranged along the front-rear direction of the refrigerator 10. That is, the short inclined surface 42 is provided between the two long inclined surfaces 41 adjacent in the front-rear direction, and the long inclined surface 41 is provided between the two short inclined surfaces 42 adjacent in the front-rear direction. That is, the two long inclined surfaces 41 adjacent in the front-rear direction are divided by the short inclined surface 42, and the two short inclined surfaces 42 adjacent in the front-rear direction are divided by the long inclined surface 41.

  The longitudinal side surface of the bottom wall of the main housing portion 21 has a mountain-shaped cross section in which peaks and valleys are alternately continued by alternately connecting a plurality of long inclined surfaces 41 and short inclined surfaces 42. And the groove part 40 is provided corresponding to the trough part. The groove portion 40 is a valley portion having a V-shaped cross section formed by the lower portion of the long inclined surface 41 and the lower portion of the short inclined surface 42.

  The vegetable case 18 includes flat portions 51 and 52. The flat portions 51 and 52 are examples of non-groove portions. On the upper surfaces of the flat portions 51 and 52, the groove portion 40, in other words, the long inclined surface 41 and the short inclined surface 42 are not provided, and the flat surface Is formed. In the present embodiment, the flat portion 51 illustrated in FIG. 4 is provided at the front portion of the bottom wall of the main housing portion 21, and the flat portion 52 illustrated in FIG. 5 is provided at the rear portion of the bottom wall of the main housing portion 21. It has been. The dimensions of the flat portions 51 and 52 in the front-rear direction can be appropriately changed and set. However, it is preferable that at least a dimension capable of inserting a human finger is secured.

  In addition, as illustrated in FIG. 6, lattice-like ribs 60 are provided on the outer surface of the vegetable case 18, in this case, the lower surface of the bottom wall of the main housing portion 21. The rib 60 is integrally provided with a plurality of horizontal ribs 61 extending in the same direction as the groove 40 and a plurality of vertical ribs 62 extending in a direction different from the groove 40. The rib 60 has a configuration in which the horizontal rib 61 and the vertical rib 62 are orthogonal to each other, and is a so-called lattice-shaped rib. The rib 60 mainly has a function of reinforcing the bottom wall of the vegetable case 18.

  A bulging portion 70 that bulges upward is provided on a part of the bottom wall of the vegetable case 18, and no rib 60 is provided on the lower surface of the bulging portion 70. The bulging part 70 is provided in the rear part of the vegetable case 18 and on the left side when viewed from the front side of the refrigerator 10, and is provided in the ice making room 15 below the vegetable room 13. Corresponds to the ice machine that does not bulge upward.

  In the part where the rib 60 is provided in the vegetable case 18, distortion of the material, that is, so-called “shrinkage” easily occurs during resin molding. That is, the thickness of the upper portion of the rib 60 tends to be slightly thinner due to so-called “shrinkage” than other portions, that is, portions where the rib 60 is not provided. Therefore, when the bottom wall of the main housing portion 21 provided with the lattice-like ribs 60 on the lower surface is viewed from above, it is formed by a plurality of long inclined surfaces 41 and short inclined surfaces 42 as illustrated in FIG. The ridgeline of the peak part extended in the horizontal direction, the trough part extended in the horizontal direction formed by the some long inclined surface 41 and the short inclined surface 42, ie, the groove part 40, and the vertical rib extended in the direction different from the groove part 40 among the ribs 60 A lattice-like pattern composed of 62 and the lateral rib 61 extending in the same direction as the groove portion 40 of the rib 60 is visible on the inner surface of the bottom wall of the main housing portion 21, in this case, the upper surface.

  According to the refrigerator 10 according to the present embodiment, the groove 40 formed by the two inclined surfaces 41 and 42 having different lengths on the inner surface of the vegetable case 18, in this case, the upper surface of the bottom wall of the main housing portion 21. Is provided. According to this configuration, as illustrated in FIG. 4, the stored item V accommodated in the main accommodating portion 21 can be supported by surface contact on the long inclined surface 41 and by line contact on the ridgeline of the mountain portion. it can. That is, since the stored material V can be supported not by point contact but by a contact mode having a certain width and area, the load applied to the stored material V can be stored in a dispersed state. In particular, it is possible to suppress the damage of the lower part of the stored item V.

  In addition, a space can be secured between the lower surface of the stored item V and the groove 40 below the stored item V. Therefore, it is possible to secure a cool air space in which cool air flows below the storage item V, and it is possible to suppress damage to the storage item V, particularly damage to the lower part of the storage item V.

  Moreover, by reflecting light on the inclined surfaces 41 and 42 constituting the groove portion 40, it is possible to form a sparkling appearance and to improve design.

  Moreover, the vegetable case 18 does not form the groove part 40 over the whole inner surface, but has the flat parts 51 and 52 in which the groove part 40 is not provided in the part. Therefore, in these flat parts 51 and 52, foreign substances, such as vegetable waste, can be easily removed, and the cleaning property can be improved. Particularly in the inside of the vegetable case 18, foreign matters such as vegetable scraps are likely to remain in the corners of the bottom wall. According to this embodiment, since the flat parts 51 and 52 are provided in the front part and the rear part which are the corners of the bottom wall of the vegetable case 18, it is possible to easily remove foreign matters that are likely to remain in the corners, and to clean them. Can be further improved.

The bottom of the vegetable case 18 includes a trough that extends in the direction, that is, the groove 40, a vertical rib 62 that extends in a direction different from the groove 40 of the rib 60, and a horizontal rib 61 that extends in the same direction as the groove 40 of the rib 60. A grid pattern is formed on the upper surface of the wall. In other words, not only the groove 40, the crest, and the trough that are intentionally formed on the inner surface of the vegetable case 18, but also the so-called “shrink” by the rib 60 that is unintentionally formed on the inner surface of the vegetable case 18, The design of the inner surface of the vegetable case 18 can be improved by a lattice pattern.

  In addition, this embodiment is not limited to embodiment mentioned above, For example, it can expand or deform | transform as follows. For example, the groove 40 may be provided not only on the bottom wall of the vegetable case 18 but also on the front wall, the rear wall, the side wall, and the like. Further, the groove 40 may have a long inclined surface on the front side and a short inclined surface on the rear side. Moreover, the groove part 40 is not restricted to what extends in the left-right direction of the vegetable case 18, For example, it is good also as a structure extended in the front-back direction of the vegetable case 18, and the direction which inclines with respect to the left-right direction or front-back direction of the vegetable case 18. It is good also as a structure extended to. Moreover, this embodiment is applicable also to storage rooms other than the vegetable compartment 13, for example, storage rooms, such as the refrigerator compartment 12, the freezer compartment 14, and an ice making room.

  In addition, as illustrated in FIG. 8, the rib 60 may be configured by only the vertical rib 62 extending in a direction different from the groove portion 40. In this case, the inner surface of the vegetable case 18 is formed by a ridgeline of a mountain portion extending in the lateral direction formed by the plurality of long inclined surfaces 41 and the short inclined surfaces 42, and the plurality of long inclined surfaces 41 and the short inclined surfaces 42. The lattice-like pattern can be visually recognized by the valley portions extending in the horizontal direction, that is, the groove portions 40 and the vertical ribs 62 extending in a direction different from the groove portions 40 of the ribs 60. Even with this configuration, not only the groove 40, the crest, and the trough that are intentionally formed on the inner surface of the vegetable case 18, but also the so-called “shrink” by the rib 60 that is unintentionally formed on the inner surface of the vegetable case 18 is used. Thus, the design of the inner surface of the vegetable case 18 can be improved by a lattice pattern.

  According to the refrigerator according to the present embodiment, the plurality of grooves provided on the inner surface of the storage chamber are formed by inclined surfaces having different lengths. According to this configuration, the stored item can be supported not by point contact but by a contact mode having a certain degree of width and area, and damage to the stored item can be suppressed.
