Description

[Detailed description of the invention] This invention provides a cooler chamber at the back of the refrigerator body, and forms an exposure recess made of synthetic resin integrally with the inner box at the bottom of the cooler chamber. To provide a drainage structure in which a drainage pipe is connected to the lower part of the drain pipe, and there is no water leakage from this connection part.

Next, embodiments of the present invention will be described in detail based on the drawings.

1 is a refrigerator body in which a heat insulating material 4 is filled between an outer box 3 and an inner box 2 which is vacuum-formed from a synthetic resin plate.
A refrigerator compartment 6 is formed at the bottom of the freezer compartment 5, and a cooler compartment 9 in which a cooler 8 is housed is provided at the back of the freezer compartment 5 between it and the inner box 2 via a partition plate 7.

Reference numeral 10 denotes an exposed concave portion formed by recessing the inner box 2 downward in the lower part of the cooler chamber 9, and a hole 11 is formed in the bottom.

A collar 14 of a drainage nozzle 13 that penetrates the wall of the main body 1 is in contact with the lower surface of the recess 10 corresponding to the hole 11 via a seal plate 12 made of rubber or the like.

Reference numeral 15 denotes a holding plate formed with a cylindrical portion 16 inserted into the hole 11, which is in contact with the bottom surface of the recess 10, and the cylindrical portion 16 extends below the boundary between the inner box 2 and the seal plate 12 to prevent drainage. This boundary is not to be invaded.

Reference numeral 17 denotes a screw that screws the retainer plate 15 and the collar 14 together so that the inner box 2 seal plate 12 is held between the retainer plate 15 and the collar 14 of the drain pipe.

Reference numeral 18 denotes an inner drain pipe whose upper enlarged portion is simply inserted into the cylindrical portion 16 and supported by the holding plate 15, and whose lower portion extends into the drain pipe 13. It faces the drain port 20 of the board 19.

21 is an electric heater provided on the back surface of the dew receiving plate 19, and 22 is an electric heater wrapped around the outer surface of the inner drain pipe 18.

As mentioned above, the presser plate 15 acts as a support member for the inner drain pipe 18, and when the screw 17 is screwed in, it sufficiently presses the inner box 2 toward the collar 14, so that even if the inner box 2 is wavy, it can be corrected. to ensure sufficient contact with the seal plate 12.

By configuring the present invention as described above, it is possible to make the connection between the inner box and the collar of the drain pipe in the exposure recessed part to a sufficient liquid-tight state with the holding plate through the sealing plate, and also to prevent molding. Even if the inner box is deformed and the sealing plate is insufficiently liquid-tight, the presence of the cylindrical portion of the holding plate prevents water from leaking into the heat insulating material from the gap between the inner box and the sealing plate.

Also, if the inner drainage pipe passes through the retaining plate as in the embodiment and receives the defrosting water from the dew receiving plate, a large amount of defrosting water will not flow through the sealing plate, which will prevent water leakage. It will be excellent as a.

The holding plate can also be used as a support member for the inner drainage pipe, and the plate structure allows easy assembly.
