Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention is designed to attach the front part of the refrigerator body so as to be spaced at a predetermined distance from the front end of the partition member that partitions the refrigerator body into a plurality of rooms. This invention relates to a refrigerator in which a partition plate is provided and a dew-proof pipe is provided along the inner surface of the partition plate.

(Prior Art) A partition member and a partition plate portion of this type of refrigerator are shown in FIG. In FIG. 4, 1 is a partition wall that is a partitioning member that partitions the inside of the refrigerator into a freezer compartment and a refrigerator compartment, and 2 is a partition plate with a U-shaped cross section that is disposed at the front of the refrigerator body. The bent parts 2a, 2a at both the upper and lower ends of the partition wall 1
The inner surface of the partition plate 2 is fitted into the extending portions 1a, 1a at the front end of the partition wall 1, so that the inner surface of the partition plate 2 has a predetermined distance from the front end of the partition wall 1. 3 is a dew-proof pipe arranged along the inner surface of the partition plate 2; 4 is a heat insulating member, such as styrene foam, filled in the gap between the front end of the partition wall 1 and the inner surface of the partition plate 2; A groove portion 4a in which the dew-proof pipe 3 is housed is formed on the front surface. As a result, since the Styrofoam 4 has some restoring force when compressed,
In the filled state, the dew prevention pipe 3 is brought into contact with the inner surface of the partition plate 2 by utilizing the above-mentioned restoring force, and also has a heat insulating effect that prevents the heat of the dew prevention pipe 3 from being transmitted to the front end of the partition wall 1. It is something that does.

(Problems to be Solved by the Invention) However, in the above conventional configuration, the dew-proof pipe 3 is brought into contact with the inner surface of the partition plate 2 due to the slight restoring force of the polystyrene foam 4.
The dimensional accuracy of the foamed polystyrene 4 must be made high. As a result, the mold for molding the styrofoam 4 has become highly accurate, and the styrofoam 4 has been molded with high precision.
The disadvantage was that the production cost was high. In addition, since the above-mentioned slight restoring force when the Styrofoam 4 is compressed is a property that disappears due to deterioration over time, the dew-proof pipe 3 no longer comes into contact with the inner surface of the partition plate 2 as time passes. However, there are also problems in terms of quality due to insufficient dew-proofing effect.

Therefore, the purpose of the present invention is to provide a refrigerator that can securely contact the dew-proof pipe along the inner surface of the partition plate, realize the structure at low cost, and prevent the problem of quality deterioration over time. It is on offer.

[Structure of the invention] (Means for solving the problems) The refrigerator of the invention is arranged such that the refrigerator body is spaced a predetermined distance from the front end of a partition member having heat insulation properties for partitioning the inside of the refrigerator body into a plurality of rooms. A metal partition plate is arranged on the front part of the main body, and a dew-proof pipe is arranged along the inner surface of this partition plate through which hot gas flows during compressor operation, and further, a metal partition plate is arranged on the front end of the partition member and the partition plate. A pressing member made of an elastic material that presses the dew-proof pipe against the partition plate is disposed within the interval between the inner surface of the plate, and a large number of protrusions are provided on the rear surface of the pressing member at the front end of the partition member. It is distinctive in that it protrudes toward the rear so as to come into contact with it.

(Function) Since the dew-proof pipe is brought into pressure contact with the partition plate by the pressing member made of an elastic material, the dew-proof pipe comes into reliable contact with the inner surface of the partition plate. Further, since the pressing member is made of an elastic material, it is possible to prevent the pressing force of the pressing member from deteriorating over time, and since dimensional accuracy during manufacture is not required so much, costs can be reduced. In particular, when a large number of protrusions are provided on the rear surface of the pressing member so as to come into contact with the front end of the partition member, the distance between the front end of the partition member and the inner surface of the partition plate varies greatly depending on the product. In addition, since the large number of projections can be deformed quite freely, the dew prevention pipe can be pressed against the partition plate with sufficient force by the pressing member.

(Example) Hereinafter, Figures 1 to 3 will be described for an example of the present invention.
This will be explained with reference to the figures.

In FIGS. 1 and 2, reference numeral 11 denotes a refrigerator body having a front opening, which is composed of an outer box 12 made of, for example, an iron plate, and an inner box 13 made of, for example, plastic, placed inside the outer box 12. There is. 1
4 has a plurality of rooms inside the refrigerator main body 11, for example, a freezer compartment 15.
and a partition wall that is a partition member that partitions the refrigerator compartment 16,
This has thermal insulation properties. Reference numeral 17 denotes a metal partition plate having a substantially U-shaped cross section, which is disposed on the front surface of the refrigerator main body 1 so that its inner surface is spaced from the front end 14a of the partition wall 14 by a predetermined distance. Here, the partition plate 17 has bent portions 17 at both upper and lower ends thereof.
a, 17a are fitted between extending portions 14b, 14b that protrude forward from both upper and lower ends of the front end portion 14a of the partition wall 14. 18 is the partition plate 17
This is a generally U-shaped dew-proof pipe arranged along the inner surface of the compressor, through which hot gas flows when the compressor is in operation.

Reference numeral 19 denotes a pressing member made of an elastic material, such as ethyl vinyl acetate-based resin, which presses against the front end 1 of the partition wall 14.
4a and the inner surface of the partition plate 17. This pressing member 19 is formed by injection molding, for example, and has a thin-walled shape as a whole.
As shown in FIG. 3, its cross section is stepped so that grooves 19a, 19a in which the dew-proof pipe 18 is positioned are formed on the front surface, and a large number of thin-walled protrusions 19b are formed on the rear surface. For example, four protrusions 19c are formed on each of these protruding pieces 19b to protrude rearward. Here, the protrusion 19 of the pressing member 19
Since the length dimension in the front-rear direction including c is set to be longer than the distance between the front end 14a of the partition wall 14 and the inner surface of the partition plate 17, the pressing member 1
The dew proof pipe 18 is pressed against the partition plate 17 by the elastic force of the elastic force 9 . Reference numeral 20 denotes a cushioning member made of foamed polyurethane, for example, which has cushioning properties and is disposed between the protrusion 19d formed on the front surface of the pressing member 19 and the inner surface of the partition plate 17. For example, an aluminum foil 21 having good thermal conductivity is sandwiched between the inner surface of the dew prevention pipe 18 and the groove 1 of the pressing member 19 so that both upper and lower ends of the aluminum foil 21 cover the outer periphery of the dew prevention pipe 18.
9a.

In the above configuration, since the pressing member 19 has higher elasticity than the conventional foamed polystyrene 4 (see FIG. 4), the dew prevention pipe 18 can be brought into reliable contact with the partition plate 17. In addition, the elastic force of the pressing member 19 is sufficiently large compared to the restoring force of the polystyrene foam 4, and there is almost no deterioration over time, so it is possible to prevent as much as possible the reduction in the force pressing against the dew prevention pipe 18 due to deterioration over time. . Furthermore, the pressing member 19 is
Since each protruding piece 19b and protrusion 19c can be deformed quite freely, the precision of the length dimension in the front and rear direction is not required so much, and a high-precision mold is not required, so compared to the past, the pressing force is reduced. The cost for manufacturing the member 19 can be reduced. In particular, a large number of protrusions 1 are provided on the rear surface of the pressing member 19.
9c is provided so as to protrude so as to come into contact with the front end of the partition wall 14, so even if the distance between the front end of the partition wall 14 and the inner surface of the partition plate 17 varies greatly from product to product, a large number of protrusions can be avoided. Since 19c can be deformed fairly freely, the dew prevention pipe 18 can be pressed against the partition plate 17 with sufficient force by the pressing member 19. In addition, the dew-proof pipe 18 is covered with the upper and lower ends of the aluminum foil 21, and the aluminum foil 21
Since the intermediate portion of the dew-proof pipe 18 is configured to be brought into contact with the partition plate 17 by the buffer member 20, the heat radiated from the dew-proof pipe 18 toward the pressing member 19 can be efficiently guided to the partition plate 17 via the aluminum foil 21. Can be done.

[Effects of the invention] As is clear from the above description, the present invention has a front part of the refrigerator main body so as to be spaced a predetermined distance from the front end of a partition member having heat insulating properties for partitioning the refrigerator main body into a plurality of rooms. A metal partition plate is placed on the inside of the partition plate, and a dew-proof pipe is placed along the inner surface of this partition plate through which hot gas flows during compressor operation.
Furthermore, a pressing member made of an elastic material is disposed within the space between the front end of the partitioning member and the inner surface of the partitioning plate, and the pressing member is made of an elastic material and presses the dew-proofing pipe against the partitioning plate, and a pressing member is provided on the rear surface of the pressing member. Since a large number of protrusions are provided to protrude rearward so as to come into contact with the front end of the partition member, it is possible to reliably contact the dew-proof pipe along the inner surface of the partition plate, and the structure is cost-effective. In addition, the problem of quality deterioration over time can be prevented, and even when the distance between the front end of the partition member and the inner surface of the partition plate varies greatly from product to product, the effects of variation can be prevented. It has the excellent effect of being able to
