An embodiment of a refrigerator will be described below with reference to the drawings. A refrigerator 10 illustrated in FIG. 1 has a plurality of types of compartments such as a refrigerating compartment 12, a vegetable compartment 13, a freezing compartment 14, and an ice making compartment 15, all of which are examples of storage compartments, inside a heat insulating box body 11 that constitutes the outer shell. It has a storage room. The refrigerating compartment 12, the vegetable compartment 13, the freezing compartment 14, and the ice making compartment 15 are partitioned so as to be vertically adjacent to each other. In this embodiment, the ice making compartment 15 is provided below the vegetable compartment 13 and on the left side of the refrigerator 10 when viewed from the front side. A small freezer compartment (not shown) is provided on the right side of the ice making compartment 15 . The refrigerator 10 has a well-known refrigerating cycle (not shown), and cold air generated by this refrigerating cycle is supplied to each storage compartment by a blowing action of a fan (not shown).

A cool air supply port 16 for supplying cool air to the vegetable compartment 13 is provided in the vegetable compartment 13 . The cold air supply port 16 constitutes a part of the cold air path, and is provided in the upper portion of the rear wall portion of the vegetable compartment 13 in this case. A damper 17 is provided at the cool air supply port 16 . The damper 17 is provided to be rotatable, and the degree of opening of the cold air supply port 16 is controlled by adjusting the amount of rotation of the damper 17 . The larger the opening of the cold air supply port 16 by the damper 17, the greater the amount of cold air supplied into the vegetable compartment 13. Conversely, the smaller the opening of the cold air supply port 16 by the damper 17, the more cold air is supplied into the vegetable compartment 13. The amount of cold air drawn is less.

A vegetable case 18 made of, for example, an opaque plastic material is provided inside the vegetable compartment 13 . The vegetable case 18 is fixed to the rear surface of a drawer-type vegetable compartment door 19 for opening and closing the vegetable compartment 13, so that the vegetable case 18 can be taken in and out of the vegetable compartment 13 as the vegetable compartment 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 partitions the interior of the vegetable case 18 into a plurality of storage portions, in this case, a main storage portion 21 and a sub storage portion 22 . The main storage portion 21 is a space formed behind 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 side of the vegetable compartment door 19, and occupies part of the vegetable case 18, in this case, the front portion. The volume of the main accommodation portion 21 is larger than the volume of the sub accommodation portion 22 .

A crisper case 30 made of, for example, a transparent plastic material is detachably attached to the upper portion of the vegetable case 18 . The crisper case 30 may be made of the same plastic material as the partition wall 20, or may be made of a different plastic material.

The main body case has a ventilation hole configured by, for example, a ratchet structure. The moisture-permeable sheet has, for example, a two-layer structure composed of a nonwoven fabric and a porous film, and is permeable to moisture in the air. The moisture-permeable sheet unit 32 absorbs moisture from the outside of the vegetable case 18 to the inside and discharges moisture from the inside of the vegetable case 18 to the outside, so that the inside of the vegetable case 18 , particularly the main storage section 21 . Adjust humidity.

Next, a configuration example of the vegetable case 18 described above will be described in further detail. The inner surface of the vegetable case 18 constitutes the inner surface of the vegetable compartment 13 when it is accommodated in the vegetable compartment 13 , that is, when the vegetable compartment door 19 closes the vegetable compartment 13 . 2 and 3, 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 container 21. As shown in FIGS. In this case, the groove portion 40 extends linearly along the left-right direction of the refrigerator 10 on the inner surface of the bottom wall of the main storage portion 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 the rear side surface of the groove portion 40 . The length dimension of the long inclined surface 41 can be changed and set as appropriate. Further, the normal direction of long inclined surface 41 is oriented toward the upper front portion of 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 the surface on the front side of the groove portion 40 . The length dimension of the short inclined surface 42 can be appropriately changed and set within a range shorter than that of the long inclined surface 41 . In addition, the normal direction of short inclined surface 42 is oriented upward at the rear of refrigerator 10 . Therefore, the normal line of the long inclined surface 41 and the normal line of the short inclined surface 42 intersect above the groove portion 40 .

Moreover, the inclination angle of the long inclined surface 41 is gentle with respect to the horizontal plane, and is preferably set within an angle range of at least 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 within an angle range of at least 45° and 90° from the horizontal plane.

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

A plurality of long inclined surfaces 41 and short inclined surfaces 42 are alternately connected to each other, so that the longitudinal side surface of the bottom wall of the main housing portion 21 has a cross section in the shape of a mountain range in which peaks and valleys are alternately continuous. And the groove part 40 is provided corresponding to the valley part. The groove portion 40 is a valley portion with 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 also has flat portions 51 and 52 . The flat portions 51 and 52 are examples of non-groove portions, and the upper surfaces of these flat portions 51 and 52 are not provided with the groove portion 40, in other words, the long inclined surface 41 and the short inclined surface 42, and are flat surfaces. is formed. In this embodiment, the flat portion 51 illustrated in FIG. 4 is provided at the front portion of the bottom wall of the main storage portion 21, and the flat portion 52 illustrated in FIG. 5 is provided at the rear portion of the bottom wall of the main storage portion 21. It is The dimensions of the flat portions 51 and 52 in the front-rear direction can be appropriately changed and set, but it is preferable to ensure at least a dimension that allows insertion of a human finger.

Further, as illustrated in FIG. 6 , grid-like ribs 60 are provided on the outer surface of the vegetable case 18 , in this case, on the lower surface of the bottom wall of the main storage portion 21 . The rib 60 integrally includes 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 that of the groove 40 . The rib 60 has a structure in which horizontal ribs 61 and vertical ribs 62 are orthogonal to each other, and is a so-called grid rib. The ribs 60 mainly function to reinforce the bottom wall of the vegetable case 18 .

A portion of the bottom wall of the vegetable case 18 is provided with a bulging portion 70 that bulges upward, and the rib 60 is not provided on the lower surface of the bulging portion 70 . The bulging portion 70 is provided in the rear portion 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 chamber 15 below the vegetable chamber 13 . It bulges upward to correspond to an ice maker that does not.

In the portion of the vegetable case 18 where the ribs 60 are provided, distortion of the material, so-called "shrinkage", is likely to occur during resin molding. That is, the portion above the rib 60 tends to be slightly thinner due to so-called "shrinkage" than the other portion, ie, the portion where the rib 60 is not provided. Therefore, when viewed from above, the bottom wall of the main housing portion 21 having the grid-like ribs 60 provided on the bottom surface is formed of a plurality of long inclined surfaces 41 and short inclined surfaces 42, as illustrated in FIG. A laterally extending trough formed by a ridge line of a laterally extending peak, a plurality of long inclined surfaces 41 and a plurality of short inclined surfaces 42, i.e., a groove 40 extending in the lateral direction, and a longitudinal rib extending in a direction different from that of the groove 40 in the ribs 60. 62 and lateral ribs 61 of the ribs 60 extending in the same direction as the grooves 40 are visible on the inner surface of the bottom wall of the main housing portion 21, in this case, on the upper surface.

According to the refrigerator 10 according to the present embodiment, the groove 40 is formed by two inclined surfaces 41 and 42 having different lengths on the inner surface of the vegetable case 18, in this case, on the upper surface of the bottom wall of the main storage portion 21. is provided. According to this configuration, as illustrated in FIG. 4, the stored material V accommodated in the main storage section 21 can be supported by surface contact on the long inclined surface 41 and by line contact on the ridges of the peaks. can. That is, since the storage object V can be supported not by point contact but by a contact mode having a certain width or area, the load applied to the storage object V can be distributed and stored. Damage to the storage material V, especially damage to the lower part of the storage material V can be suppressed.

In addition, a space can be secured between the bottom surface of the storage material V and the groove portion 40 below the storage material V. As shown in FIG. Therefore, it is possible to secure a space for cool air to flow below the stored items V, and to prevent damage to the stored items V, especially damage to the lower portion of the stored items V.

In addition, since the light is reflected on the inclined surfaces 41 and 42 forming the groove 40, it is possible to form a glittering appearance and improve the design.

In addition, the vegetable case 18 does not form the groove 40 over the entire inner surface, but has flat portions 51 and 52 on which the groove 40 is not provided. Therefore, in these flat portions 51 and 52, foreign matter such as vegetable waste can be easily removed, and cleaning can be improved. In particular, inside the vegetable case 18, foreign matter such as vegetable waste tends to remain at the corners of the bottom wall. According to the present embodiment, since the flat portions 51 and 52 are provided at the front and rear corners of the bottom wall of the vegetable case 18, foreign matter that tends to remain in the corners can be easily removed, resulting in easy cleaning. can be further improved.

Further, according to the present embodiment, the ridge lines of the crests extending in the horizontal direction formed by the plurality of long inclined surfaces 41 and the short inclined surfaces 42 and the lateral ridges formed by the plurality of long inclined surfaces 41 and the short inclined surfaces 42 are formed. The bottom of the vegetable case 18 is formed by the valleys or grooves 40 extending in the same direction, the vertical ribs 62 of the ribs 60 extending in a direction different from that of the grooves 40, and the horizontal ribs 61 of the ribs 60 extending in the same direction as the grooves 40. A grid pattern is formed on the upper surface of the wall. That is, using not only the grooves 40, peaks, and valleys that are intentionally formed on the inner surface of the vegetable case 18, but also the so-called "shrinkage" due to the ribs 60 that are 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 the lattice pattern.

In addition, this embodiment is not limited to the embodiment described above, and can be expanded or modified as follows, for example. For example, the groove portion 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 walls, and the like. Further, the groove portion 40 may have a long inclined surface on the front side and a short inclined surface on the rear side. Moreover, the groove portion 40 is not limited to extending in the left-right direction of the vegetable case 18. For example, the groove portion 40 may be configured to extend in the front-rear direction of the vegetable case 18, or in a direction inclined with respect to the left-right direction or the front-rear direction of the vegetable case 18. It is good also as a structure extended to. Moreover, this embodiment can be applied to storage compartments other than the vegetable compartment 13, such as the refrigerator compartment 12, the freezer compartment 14, and the ice making compartment.

Further, as illustrated in FIG. 8 , the rib 60 may be composed only of a vertical rib 62 extending in a direction different from that of the groove 40 . In this case, the inner surface of the vegetable case 18 is formed by a ridge line of laterally extending peaks formed by a plurality of long inclined surfaces 41 and short inclined surfaces 42 and a plurality of long inclined surfaces 41 and short inclined surfaces 42 . A grid-like pattern is visible due to the laterally extending troughs or grooves 40 and the longitudinal ribs 62 of the ribs 60 extending in a direction different from that of the grooves 40 . This configuration also utilizes not only the grooves 40, peaks, and valleys that are intentionally formed on the inner surface of the vegetable case 18, but also the so-called "shrinkage" due to the ribs 60 that are unintentionally formed on the inner surface of the vegetable case 18. As a result, the design of the inner surface of the vegetable case 18 can be improved by the lattice pattern.

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