FIG. 13 is a sectional view of a main part of a conventional refrigerator.

[0004] Reference numeral 1 denotes a refrigerator main body, which is constituted by a heat insulating box body 5 in which a heat insulating material 4 is foam-filled between an outer box 2 and an inner box 3. A part corresponding to the side of the heat insulating partition wall 6 which is vertically divided by the attached pre-partition member and the heat insulating partition wall 6 fixed to the rear side of the pre-partition member after filling the heat insulating material 4. On the outer surface of the inner box 3, a stop plate 7 made of a hard resin is attached to the upper and lower chambers defined by the heat insulating partition wall 6, and the heat insulating partition wall 6 is fixed to the stop plate 7.

[0005] Since the partition member is fixed to the stopper plate 7, the stopper plate 7 extending over the upper and lower chambers is filled with the inner jig through the inner box 3 when the heat insulating material 4 is filled. The inner box can be prevented from being deformed due to the foaming pressure.

Further, the amount of heat traveling between the upper and lower chambers along the stop plate 7 can be minimized.

[0007]

However, in the above-mentioned conventional construction, the partition wall 6 is attached to the inner box 3 via the stopper plate 7, and the stopper plate 7 is fixed to the inner box 3 with screws or the like. The upper and lower chambers are not completely airtight and are not partitioned off. Especially when the room temperature difference between the upper and lower chambers is extremely large, heat exchange between the rooms is promoted and not only a predetermined room temperature cannot be secured, but also in food management. Quality could not be maintained.

In addition, since parts such as the stop plate 7 and screws are required, the number of parts is increased, and the number of man-hours is also increased, resulting in an increase in cost.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a refrigerator in which a partition portion for partitioning a storage room has improved sealing and heat insulating properties.

[0010]

In order to achieve this object, a refrigerator according to the present invention comprises a refrigerator body in which an inner box is arranged in an outer box and a foam insulating material is filled between the two boxes. In a refrigerator, the refrigerator comprises a vertical partition plate for partitioning a storage room left and right, and a horizontal partition plate positioned above the vertical partition plate and partitioning the storage room up and down, wherein the horizontal partition plate and the vertical partition plate are foam-insulated. Before filling with the material, it is inserted into the inner box, integrally foamed with the foamable heat insulating material, and attached.

Thus, the vertical partition and the horizontal partition forming the storage room can be formed without gaps, and stable cooling performance can be secured.

Further, the present invention provides a method for filling a horizontal partition plate with the foamable heat insulating material, and allowing the foamable heat insulating material to leak from a lower portion of the horizontal partition plate to join the horizontal partition plate and the vertical partition plate. The part is fixed with a seal.

[0013] Thus, since the horizontal partition plate does not bend due to the foaming pressure of the heat insulating material, the doors attached to the vertical partition plate can be kept in balance, so that it is possible to provide a refrigerator which is stable in quality.
