  The container 10 of the refrigerator of Example 1 of this invention is demonstrated using FIGS. 1-4.

  The container 10 of this embodiment is a drawer-type container housed in a freezer compartment of a refrigerator, and is placed on a pair of left and right rails 12 and 12 provided on both side surfaces of the freezer compartment. By pulling the freezer compartment doors forward, the containers 10 placed on the rails 12, 12 are also drawn forward.

  The container 10 is composed of an outer container 14 and an inner container 16, and is a double container in which the inner container 16 is fitted inside the outer container 14.

  The outer container 14 includes a bottom plate 18, a front plate 20, left and right side plates 22 and 24, and a rear plate 26. Similarly, the inner container 16 includes a bottom plate 28, a front plate 30, left and right side plates 32 and 34, and a rear plate 36. The rear plate 26 is formed to have a lower height than the other plates 20 to 24, and the rear plate 36 is formed to have a lower height than the other plates 30 to 34, and cold air enters the container 10 from the rear. it can. The outer container 14 and the inner container 16 are formed by injection.

  Outer flange portions 40 extending outward are formed at the upper ends of the left and right side plates 22 and 24 of the outer container 16. Further, the bottom plate 18 has a flat surface. Rectangular openings 38 and 38 are opened in front upper portions of the left and right side plates 22 of the outer container 14.

  An inner flange portion 43 extending outward is formed at the upper ends of the bottom plate 28, the front plate 30, the left and right side plates 32, 34 and the rear plate 36 of the inner container 16. A plurality of ribs 43 projecting in the front-rear direction are formed on the upper surface of the bottom plate 28, and ribs 44 projecting downward are formed in a mesh shape on the lower surface of the bottom surface 28. Openings 42 and 42 are opened in front upper portions of the left and right side plates 32 and 34 of the inner container 16. Steps 46 projecting outward are formed at the edges of the openings 42, 42 as shown in FIG.

  When the inner container 16 is fitted into the outer container 14, a slight gap 48 is formed between the inner container 16 and the outer container 14 as shown in FIG. 3. Further, since the ribs 44 of the bottom plate 28 are placed on the flat bottom plate 18, the bottom plate 18 and the bottom plate 28 also have a gap 50 formed therein.

  An inner flange portion 43 is fitted over the outer flange portion 40. As shown in the enlarged view of FIG. 3, the inner flange portion 43 includes a first extending portion 52 extending in the horizontal direction from the left side plate 32 and a second extending portion extending downward from the first extending portion 52. 54, and a plurality of support ribs 56 are formed at predetermined intervals inside the U-shape. The support rib 56 is placed on the upper surface of the outer flange portion 40, and the inner flange portion 43 is placed on the outer flange portion 40. Further, the outer flange portion 40 is placed on the rail 12.

  An opening 38 opened in the left side plate 22 of the outer container 14 and an opening 42 opened in the left side plate 32 of the inner container 16 are opened at positions facing each other. A blowing member 58 separate from the container 10 is fitted. As shown in FIG. 4, the blowing member 58 is provided with a cylindrical portion 64 so as to surround the entire circumference of the slit surface 62 in which a plurality of slits 60 are opened, and the cylindrical portion 64 penetrates both the opening portions 38 and 42. Fixed. A cylindrical flange portion 66 is formed at one end of the cylindrical portion 64 and is fitted to the stepped portion 46 described above. Further, in order to fix the cylindrical portion 64 to the openings 38 and 42, a claw portion 68 protrudes from the other end of the cylindrical portion 64 and engages with the left side plate 22 of the outer container 14. Further, in order to completely fix the cylindrical portion 64 to the container 10, a soft tape 70 is affixed between the cylindrical flange portion 66 and the stepped portion 46, and the claw portion 68 of the cylindrical portion 64 and the outer container 14 are A soft tape 72 is pasted between the left side plate 22 and the left side plate 22. The reason why the blowing member 58 is fastened with the soft tapes 70 and 72 is to prevent water from entering the gap 48 in addition to fixing. An opening 38 opened in the right side plate 24 of the outer container 14 and an opening 42 opened in the right side plate 34 of the inner container 16 are also opened at positions facing each other. A blowing member 58 separate from the container 10 is fitted in the same manner as the left side.

  When the container 10 is placed on the pair of left and right rails 12 and 12 of the freezer compartment, the outer flange portions 40 and 40 of the outer container 14 are placed on the pair of left and right rails 12 and 12 as shown in FIG. To do.

  According to the container 10 of the present embodiment, since the outer flange portion 40 is placed on the pair of left and right rails 12 and 12, the container 10 is not detached from the rails 12 and 12 when the container 10 is pulled out. Can be shown beautifully.

  Further, since the inner flange portion 43 is formed in a substantially U-shape and the outer flange portion 40 is placed on the support rib 56 inside the inner flange portion 43, even if a load is applied to the flange portions 40, 43, the inner container 16 and the outer container 14 do not come off.

  Further, since gaps 48 and 50 are formed between the outer container 14 and the inner container 16, the heat insulation function works by the air in these gaps 48 and 50.

  Moreover, since the blowing member 58 having the slit 60 is fitted on both side surfaces of the container 10, the cold air that has entered from the rear flows out to both sides through the blowing member 58 without staying inside the container 10.

  Further, since the air blowing member 58 has a structure in which the slit 60 is provided in the slit surface 62 inside the cylindrical portion 64, the air blowing member 58 has a gap from the air blowing member 58 even if the air blowing member 58 penetrates the outer container 14 and the inner container 16. The cool air does not enter 48 and the heat insulating effect of the gap 48 can be maintained.

  Next, the refrigerator container 10 according to the second embodiment of the present invention will be described with reference to FIGS. 5 and 6.

  The difference between the structure of this embodiment and Embodiment 1 is that the structure of the outer container 14, the structure of the blower member 58, and the drain hole 80 are provided.

  In the first embodiment, the outer container 14 is formed by injection, but in the present embodiment, the outer container 14 is formed by assembling using the self-hinge portion 74. When the outer container 14 and the inner container 16 are manufactured by injection, since a draft is required as a mold structure, a dead space exists between the inside of the freezer compartment and the container 10. Therefore, in this embodiment, in order to suppress a reduction in the storage volume, the outer container 14 is formed not by injection but by assembly.

  As shown in FIG. 5, in the outer container 14, the front plate 20, the left side plate 22, the right side plate 24, and the rear plate 26 are connected to the bottom plate 18 by a self-hinge part 74, and the plates 20 to 26 are directed upward. It can be bent.

  Two protrusions 76 protrude from the front end portion and the rear end portion of the left side plate 22, and when the plates 20 to 26 are bent upward, the front plate 20 and the rear plate are located inside the protrusions 76 and 76. 26 is fitted and fixed. Further, in order to further fix each of the plates 20 to 26, a soft tape 78 is provided inside the protrusions 76 and 76 to fix both sides of the front plate 20 and both sides of the rear plate 26. The reason why the plates 20 to 26 are fixed by the soft tape 78 is to prevent water from entering and to improve the sealing performance.

  When assembling the outer container 14 with the structure of the self-hinge part 74, it is possible to eliminate the draft angle as in the prior art, so that a heat insulating layer is formed without creating a dead space, and the reduction in the storage volume is minimized, It can be a double container. In addition, although each plate 24-26 was fixed with the protrusion 76, it may replace with this and may be fixed with a screw.

  Further, as shown in FIG. 6, in the present embodiment, the air blowing member 58 is integrated with the inner container 16. That is, a slit surface 62 provided with a plurality of slits 60 is formed on the right side plate 24, and the cylindrical portion 64 protrudes from the left side plate 22 so as to surround the slit surface 62. A claw portion 68 is provided at the tip of the cylindrical portion 64. When the inner container 16 is fitted inside the assembled outer container 14, the claw part 68 of the cylindrical part 64 is engaged with the opening 38 in the outer container 14, and the blowing member 58 is formed in the container 10. Also in this case, since the air blowing member 58 is formed from the cylindrical portion 64, the heat insulating effect of the gap 48 can be maintained, and the cool air inside the container 10 can be flowed to both sides through the slit 60.

  Further, as shown in FIGS. 5 and 6, in this embodiment, a drain hole 80 is provided in the bottom plate 28 of the outer container 14. This drain hole 80 is for draining water in the unlikely event that water enters between the outer container 14 and the inner container 16. If there is a possibility that the heat insulating property may be deteriorated by the drain hole 80, a screw or a claw-fitting cover is detachably provided in the drain hole 80. You may remove the lid and drain the water.

  Further, as shown in FIG. 6, in this embodiment, the side end portion of the outer flange portion 40 of the outer container 14 is an engagement hole 82 provided in the second extending portion 54 of the inner flange portion 43 of the inner container 16. And the outer container 14 and the inner container 16 are fixed.

Example of change

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof.

  For example, in each of the above embodiments, the gaps 48 and 50 between the inner container 16 and the outer container 14 are air layers, but instead of this, insertion of a heat insulating member such as glass wool or EPS, or filling with a foaming agent. By doing so, the heat insulating property may be further improved.

  Moreover, although the said each Example demonstrated with the container of the freezer compartment, it may replace with this and may apply to the container of a vegetable compartment or a freezer compartment.
