Generally, a refrigerator cabinet fills and foams a heat-insulating material in a filling space formed by an inner box and an outer box to achieve heat insulation between the refrigerator, the outside, and each storage room provided in the refrigerator. In order to prevent the inner box and the like from being deformed by the pressure of the heat insulating material during filling and foaming of the heat insulating material, a foaming jig is housed inside the inner box to reinforce the inner surface of the inner box.
In addition, the refrigerator cabinet is provided with a dew-proof pipe for preventing condensation generated in the refrigerator due to a temperature difference between each storage room and the outside air on the front surface of the cabinet and a partition plate that partitions the cabinet into each storage room. .

  However, in a conventional refrigerator cabinet, when a foaming jig is stored in the inner box, a dew-proof pipe (projecting dew-proof pipe) that protrudes from the horizontal partition plate and is attached to the vertical partition plate is bent and the foam jig is used. The work was to stretch the protruding dew-proof pipe after holding and foaming the insulation. For this reason, there existed a subject that a protrusion dew-proof pipe deform | transforms by the work mistake, or was damaged (for example, refer patent document 1).

  Also, in the conventional refrigerator cabinet, there is a method of dividing the foaming jig to store the foaming jig inside the inner box without bending the protruding dew-proof pipe, but the foaming jig is stored inside the inner box. There is a problem that the work to be performed becomes complicated (see, for example, Patent Document 2).

  The present invention has been made in order to solve the above-described problems, and a refrigerator in which a work for storing a foaming jig in an inner box is easy without the protruding dew-proof pipe being deformed or damaged. The goal is to get the cabinet. Moreover, it aims at obtaining the refrigerator using this cabinet.

  The refrigerator cabinet according to the present invention comprises an inner box and an outer box, and a refrigerator cabinet in which a space formed between the inner box and the outer box is filled with a heat insulating material is foamed. A plurality of storage chamber spaces are formed by one or a plurality of horizontal partition members that vertically divide the internal space of the cabinet, and one or a plurality of vertical partition plates that divide the internal space partitioned by the horizontal partition members left and right. The at least one front surface portion of the vertical partition plate is provided with a protruding dew-proof pipe protruding from the horizontal partition member disposed at a position intersecting with the vertical partition plate. At least the rear part of the protruding horizontal partition member has a protruding part that functions as a jig for preventing deformation of the storage chamber space during the filling and foaming in the same direction as the protruding dew-proof pipe. Is formed so as to inner surface facing the inner box Te, length of projection from the horizontal partitions of said protruding anti-condensation pipe is shorter than the length of the vertical partition.

In the refrigerator cabinet according to the present invention, since the protruding length of the protruding dew-proof pipe from the horizontal partition member is shorter than the length of the vertical partition plate, the protruding dew-proof pipe and the side of the side where the protruding dew-proof pipe is not provided. An insertion space for the foaming jig is secured between the partition member (or cabinet). In addition, at least the rear part of the horizontal partition member from which the protruding dew-proof pipe protrudes has a protruding part that functions as a jig for preventing deformation of the storage chamber space during filling and foaming in the same direction as the protruding dew-proof pipe. And since it is formed so as to face the inner surface of the inner box, it is not necessary to press the inner rear surface of the inner box at a position facing the protruding dew-proof pipe with a foaming jig.
Therefore, the thickness of the foaming jig passing through the insertion space formed above or below the protruding dew-proof pipe can be made smaller than this insertion space, so that the protruding dew-proof pipe is not deformed or damaged. A foaming jig can be stored. Moreover, since the foaming jig accommodated in the storage chamber space provided with the protruding portion can be an integral type, the work of housing the foaming jig can be easily performed.

  Drawing 5 is a figure of the state where urethane foaming jig was stored in cabinet 1 of the refrigerator in one embodiment of the present invention, (a) is a front view and (b) shows a side section schematic diagram. The manufacturing process of the cabinet 1 is demonstrated using this figure.

Step 1.
The outer box 11 and the inner box 12 are assembled to form the outer portion of the cabinet 1, and the horizontal partition member 20, the horizontal member 40, and the horizontal member 50 are attached to the inside of the cabinet 1. Thereafter, a dew-proof pipe 60 is disposed on these front portions. Further, a protruding dew-proof pipe 61 to be provided on the front surface portion of the vertical partition plate 30 is disposed so as to protrude from the horizontal partition member 20.

Step 2.
As shown in FIG. 5, the space formed by the rear surface of the horizontal member 40, the side surface and the rear surface of the cabinet 1 is a substantially rectangular parallelepiped plate member between the horizontal member 40 and the protruding dew-proof pipe 61. The foaming jig 100 is attached. Further, the foaming jig 101 is attached above the horizontal installation member 40 and the foaming jig 100 from between the horizontal installation member 40 and the protruding dew-proof pipe 61. The foaming jig 101 is composed of a bottom surface portion 101a that is a substantially rectangular parallelepiped plate-shaped member and side surface portions 101b that stand from both side portions of the bottom surface portion 101b. It has a shape.

  These foaming jigs 100 and 101 are for preventing the inner surface of the inner box 12 from being deformed when a space formed by the outer box 11 and the inner box 12 is filled with a heat insulating material. Further, the protruding portions 21 and 22 formed on the horizontal partition member 20 also serve to prevent the inner surface of the inner box 12 from being deformed. In addition, the inner surface of the inner box 12 that is not protected by the foaming jig 100, the foaming jig 101, the protruding portion 21, and the protruding portion 22 is protected by another foaming jig (not shown).

  In the present embodiment, the thicknesses of the foaming jig 100 and the bottom surface portion 101a are both about 50 mm, which is sufficiently larger than the dimension of the space formed by the horizontal installation member 40 and the protruding dew-proof pipe 61. Small. For this reason, when attaching the foaming jigs 100 and 101, the protruding dew-proof pipe 61 is not deformed or damaged by colliding with the protruding dew-proof pipe 61.

Step 3.
A space formed by the outer box 11 and the inner box 12 is filled with a heat insulating material and foamed. At the time of filling and foaming, foaming pressure is applied to the outer box 11 and the inner box 12, and the resin inner box 12 having a lower strength than the outer box 11 formed of a metal plate tends to be deformed. If the inner box 12 is deformed and the internal space of the cabinet 1 is narrowed, the vertical partition plate 30, the horizontal partition plate 41, the horizontal partition plate 51, the fan grill 70, and the like that are installed in the cabinet 1 after filling and foaming cannot be attached. End up.
However, in the present embodiment, the inner box 12 is deformed by the foaming jig 100, the foaming jig 101, the projecting part 21, the projecting part 22, and other foaming jigs (not shown), and the interior of the cabinet 1. The space is prevented from becoming narrow.

Step 4.
The foaming jig 100, the foaming jig 101, and other foaming jigs (not shown) are removed. Also at this time, the thicknesses of the foaming jig 100 and the bottom surface portion 101a are both about 50 mm, which is sufficiently smaller than the dimension of the space formed by the horizontal installation member 40 and the protruding dew-proof pipe 61. For this reason, when attaching the foaming jigs 100 and 101, the protruding dew-proof pipe 61 is not deformed or damaged by colliding with the protruding dew-proof pipe 61.

Step 5.
As shown in FIG. 3, the inner box is formed from the space formed by the rear surface of the horizontal installation member 40, the side surface and the rear surface of the cabinet 1, and the space formed by the rear surface of the horizontal installation member 50, the side surface and the rear surface of the cabinet 1. A fan grill 70, a cooler 71, and the like are attached to the rear surface of Twelve. Then, the horizontal partition plate 41 and the horizontal partition plate 51 are attached. The thickness of the horizontal partition plate 41 is also sufficiently smaller than the dimension of the space formed by the horizontal installation member 40 and the protruding dew-proof pipe 61, about 90 mm. For this reason, when attaching the foaming jigs 100 and 101, the protruding dew-proof pipe 61 is not deformed or damaged by colliding with the protruding dew-proof pipe 61.

Step 6.
The vertical partition plate 30 is attached in a state where the cushion 32 and the metal foil 33 are inserted in front of the vertical partition member 31. The vertical partition plate 30 is structured to be fitted and attached from the lateral direction in order to prevent deformation and breakage of the protruding dew-proof pipe 61. Thereafter, the metal foil 34, the cushion 35 and the metal panel 36 are attached in front of the protruding pipe 61.

  Since the fan grill 70 and the cooler 71 need to be attached after filling and foaming, the horizontal member 40 and the horizontal partition plate 41 have a split structure, but do not interfere with the fan grill 70 after installation, and the fan The horizontal partition plate 41 may be used in place of the foaming jig 100 if there is no problem with the mounting of the grill 70. At this time, the horizontal installation member 40 and the horizontal partition plate 41 may be integrated. Moreover, you may provide the protrusion part which prevents a deformation | transformation of the inner box 12. FIG.

  Further, in this embodiment, the side surface of the inner box 12 forming the ice making chamber and the switching chamber is protected by the protruding portion 20c of the horizontal partition member 20 and the side surface portion 101b of the foaming jig 101, but the protruding portion 20c or It is also possible to extend the length of any one of the side surface portions 101b and protect the side surface of the inner box 12 forming the ice making chamber and the switching chamber by only one side.

Then, the experimental result of the heat transfer property from the protrusion dew prevention pipe 61 to the metal panel 36 (front surface of the vertical partition plate 30) is demonstrated using FIGS.
FIG. 6 is a cross-sectional view of the front portion of the vertical partition plate 30. FIG. 6A shows a cross-sectional view of the vertical partition plate 30 in the embodiment of the present invention in which the protruding dew-proof pipe 61 is disposed between the metal foil 33 and the metal foil 34. 6 (b) and 6 (c) are cross-sectional views of the front portion of the vertical partition plate 30 for comparison experiments, and FIG. 6 (b) shows the vertical partition plate 30 on which the metal foil 34 is not disposed. A cross-sectional view is shown, and FIG. 6C shows a cross-sectional view of the vertical partition plate 30 on which the metal foil 33 is not disposed.
FIG. 7 is a diagram illustrating measurement points for measuring the temperature of the metal panel 36 (the front surface of the vertical partition plate 30). Moreover, FIG. 8 is a measurement result of the temperature of the metal panel 36 (front surface of the vertical partition plate 30) in the measurement points 1-5 shown in FIG. 7, FIG. 8 (a) is FIG. 8 (b), FIG. 8 (b), and FIG. 8 (c) are views of the metal panel 36 (front surface of the vertical partition plate 30) in the vertical partition plate 30 shown in FIG. 6 (c), respectively. The measurement result of temperature is shown.

  As shown in FIG. 8, at each of the measurement points 1 to 5, the temperature of the metal panel 36 (FIG. 8A) of the vertical partition plate 30 according to the embodiment of the present invention is other specifications ( It is higher than the temperature of the metal panel 36 (FIGS. 8B and 8C) of the vertical partition plate 30 in FIGS. 6B and 6C. Moreover, also in the average temperature of the measurement points 1-5, the temperature of the metal panel 36 (FIG. 8 (a)) of the vertical partition plate 30 in one embodiment of this invention is other specifications (FIG. 6 (b) and It is higher than the temperature of the metal panel 36 (FIGS. 8B and 8C) of the vertical partition plate 30 in (c)). From this, it can be seen that the vertical partition plate 30 in the embodiment of the present invention in which the protruding dew-proof pipe 61 is arranged between the metal foil 33 and the metal foil 34 has good heat transfer to the metal panel 36. .

In the refrigerator cabinet 1 configured as described above, the protruding length of the protruding dew-proof pipe 61 from the lower surface of the horizontal partition plate 20a is shorter than the height of the vertical partition plate 30. An insertion space for the foaming jig 100 and the foaming jig 101 is secured in a space formed between the members 40. Moreover, since the protrusion part 20b which fulfill | performs the function of the jig | tool for preventing the deformation | transformation of a storage chamber space in the case of filling foaming is formed in the rear part of the horizontal partition member 20, it opposes the protrusion dew-proof pipe 61. It is not necessary to press the inner rear surface of the inner box 12 at the position with the foaming jig 100 or the foaming jig 101.
Therefore, since the thickness of the foaming jig 100 and the foaming jig 101 passing through the insertion space formed below the protruding dew-proof pipe 61 can be made smaller than this insertion space, the protruding dew-proof pipe 61 is deformed, The foaming jig 100 and the foaming jig 101 can be accommodated without being damaged. In addition, since the foaming jig 100 and the foaming jig 101 can be integrated, the work of housing the foaming jig 100 and the foaming jig 101 can be easily performed.

  Further, since each of the metal foil 33 and the metal foil 34 is provided so as to sandwich the protruding dew-proof pipe 61 by the elastic force of the cushion 32 and the cushion 35, the metal foil 33 and the metal foil 34 are protruded. This heat is transmitted to the metal panel 36, so that the entire region of the metal panel 36 (the front surface of the vertical partition plate 30) can be heated even if the protruding pipe 61 is not provided on the entire front surface of the vertical partition plate 30.
