[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the duct according to the present invention will be described with reference to the accompanying drawings. Note that the same members as those already described with reference to FIGS. 6 and 7 are designated by the same reference numerals, and description thereof will be omitted.
[0008]
First, the internal duct structure according to the present embodiment will be described with reference to FIGS. In the interior duct structure shown in FIG. 1, the interior duct main body 37 is formed in a box shape by bending a sheet metal to include the bottom plate 24, the side plates 25, and the back plate 26. The in-compartment duct main body 37 is slightly larger than the communication port 4 in consideration of ease of attachment. Screw holes 40 and 41 as attachment means for attaching an L-shaped flange 38 are formed in the vicinity of both side plate sides of the bottom plate 24 and the side plate 25, respectively. The L-shaped flange 38 is formed by bending a sheet metal and has a long side duct side mounting surface 42 and a short side warehouse inner side mounting surface 43. The duct side mounting surface 42 corresponds to the screw hole 41. A long hole 44 is formed, and a screw hole 45 for screwing to the inner surface of the refrigerator is formed in the inner mounting surface 43 of the refrigerator.
A screw hole 47 for attaching the partition plate 22 is formed in the rear plate 26, and the long hole 51 formed in the partition surface 50 of the partition plate 22 is screwed to the screw hole 47 to be partitioned. The plate 22 is attached. The width of the partition plate 22 is substantially equal to the width of the communication port 4, and an adhesive surface 52 to which a sealing material is attached is formed on the upper end surface of the partition plate 22. By pressing the adhesive surface 52 of the partition plate 22 against the bottom of the refrigerator unit and fixing the same, the communication port 4 is partitioned into a cool air suction side and a cool air discharge side.
[0009]
Next, a method of attaching the internal duct will be described. When the inner width is large enough to mount the inner duct 23, the inner mounting surface 43 of the L-shaped flange 38 and the upper end of the side plate 25 are first aligned, and the screw hole 41 and the long hole 44 are formed. The L-shaped flange 38 is fixed to the internal duct main body 37 by screwing (FIG. 1: position S). Next, the inside duct 23 is aligned with the communication port 4 of the cooling storage ceiling surface 30, and the screw hole 45 of the L-shaped flange 38 inside mounting surface 43 of the cooling storage is screwed to the cooling storage ceiling surface 30. Attach. Further, since the partition plate 22 is slidably attached to the screw hole 47 of the rear plate 26 of the duct 23 in the refrigerator through the long hole 51, the partition plate 22 is pushed up and pressed against the bottom surface of the refrigerator unit. Is attached, and the communication port 4 is divided into a cold air suction side and a cold air outlet side, whereby the installation of the in-compartment duct 23 is completed.
[0010]
When the inner width of the refrigerator is not large enough to mount the inner duct 23, first, the duct-side mounting surface 42 of the L-shaped flange 38 is adjusted to the inner width of the inner duct 23 with respect to the inner duct 23 bottom plate 24. The L-shaped flange 38 is fixed to the internal duct main body 37 by screwing the screw hole 40 and the long hole 44 (FIG. 1: position D). Next, as shown in FIG. 2, the inside duct 23 is aligned with the communication port 4 of the cooling storage ceiling surface 30, and the screw hole 45 of the L-shaped flange 38 inside mounting surface 43 of the cooling storage is screwed to the inside surface 53 of the cooling storage. It is stopped and the inside duct 23 is attached. Further, the installation of the in-compartment duct 23 is completed by attaching the partition plate 22 described above.
[0011]
As shown in FIG. 3, even if the inner width of the refrigerator is slightly increased, the L-shaped flange 38 slides on the duct main body 37 in the refrigerator due to the elongated hole 44 on the duct side mounting surface 42 of the L-shaped flange 38. Since it is mounted as possible, it is only necessary to loosen the screw 54 to shift the position of the L-shaped flange 38 and screw it again, so that it can be easily mounted to a cooling storage having a different internal width dimension.
[0012]
As described above, since the attachment position of the L-shaped flange is provided so as to be changeable with respect to the duct main body in the compartment, even in a cooling storage having a small interior compartment width, the attachment can be easily performed simply by changing the attachment position of the L-shaped flange. . In addition, even in a cooling storage having a small internal storage width, the duct inside the storage can be attached to the entire internal width of the storage. It is now possible to mount a large-class refrigerator unit that requires a large communication port. In addition, the long hole is provided on the duct side mounting surface of the L-shaped flange, so that the L-shaped flange can be slidably mounted on the duct body in the refrigerator, and can accommodate cooling storages with different widths in the refrigerator. Can be. Therefore, it is possible to use a common duct for the cooling storages having different internal widths.
[0013]
The present invention is not limited to the contents of the above-described embodiment, and various improvements and modifications can be made without departing from the gist of the present invention. For example, although the long hole is provided in the L-shaped flange, it may be provided in the duct in the refrigerator. Further, the flange is L-shaped, but the flange is not limited to the L-shape as long as it has an inside mounting surface and a duct-side mounting surface.
[0014]
【The invention's effect】
As described above, according to the internal duct structure of the present invention, the internal duct can be easily attached regardless of whether the internal width is large or small.
