It corresponds to one direction in which the other end side insertion port 42 of the room drainage pipe is formed in parallel (both are the left and right directions in FIGS. 7 and 9), and one flange portion 22a is for integration. The other flange part 22b overlaps with the jig in the vertical direction, and the other flange part 22b is attached from the integration jig 3 so that the second mounting hole 24b formed in the other flange part does not overlap with the integration jig in the vertical direction. It is also formed prominently.

Furthermore, in this embodiment, by forming the predetermined direction to coincide with one direction, the space occupied by the entire structure is suppressed compared to a case where these two directions do not coincide and are orthogonal to each other, for example. be able to. Note that by forming the second attachment hole 24b of the other flange portion so as not to overlap the integration jig in the vertical direction, work such as attaching screws to the second attachment hole 24b becomes easier.

A second installation tool insertion opening 53 having a shape corresponding to the first installation tool insertion opening 43 is provided at a portion of the rotatable portion 5 that faces one of the flange portions 22a in the folded state. By forming the first installation tool insertion opening 43 and the second installation tool insertion opening 53, the installation tool can be inserted into the second installation hole 24a at one flange portion 22a through these openings. It is possible to tighten screws, etc.

Further, as shown in FIGS. 5 and 6, the second mounting hole 24a of one flange part 22a of the freezer compartment drain pipe attachment part 22 does not overlap the refrigerator compartment drain pipe 11 in the vertical direction, so that the refrigerator compartment drain pipe 11 can be avoided from obstructing the work of attaching screws to the second attachment hole 24a.

In the present invention, by configuring the integration jig 3 as described above, the rotatable part 5 can be formed in the jig main body 4 by simply rotating the rotatable part 5 with respect to the jig main body 4 until it is in a folded state. The plurality of lock hooks 44 are respectively hooked to the plurality of lock holes 54 of the rotatable part 5 and locked, thereby allowing each of the refrigerator compartment drain pipe 11 and the freezer compartment drain pipe 21 to be locked with a simple rotation and locking operation. The end 11b and the other end 21b can be firmly fixed to the integration jig 3, greatly improving operability.

In the above, we have explained the situation where gaskets are installed between the refrigerator compartment drain pipe attachment part and the refrigerator compartment water outlet, and between the freezer compartment drain pipe attachment part and the freezer compartment water outlet. Gaskets 7 may also be installed between the other ends of the pipe and the freezer compartment drain pipe and the integration jig, respectively.

A drainage outlet 64 is included.

Further, as shown in FIGS. 7 and 9, the drainage confluence port 62 is located at a lower position in the drainage receiving portion 61 than other parts of the drainage receiving portion, which is advantageous for the merging of drainage. be.

Further, as shown in FIGS. 7 and 9, the drainage guide portion 63 is formed to be thinner on the downstream side of drainage than on the upstream side. With this configuration, when the water flow is large, the structure in which the tip is tapered buffers the water flow and prevents the water flow from scattering.

Further, as shown in FIGS. 7 and 9, a lid portion 65 is attached to the drainage outlet 64 of the drainage guide portion 63, and as shown in FIGS. 11A and 11B, the lid portions 25, 65 are The lid part can be opened by the impact of the discharged water, and when there is little or no drainage, the drainage outlet can be restored to the closed state by its own gravity.

Note that a lid portion 25 is also attached to the port on the other end side of the freezer compartment drain pipe, and the lid portion 25 is configured in the same manner as the lid portion 65.

By forming the lid as described above, when there is drainage, the lid automatically opens to let the drainage flow out, and when there is no drainage, the lid automatically opens due to its own gravity. By closing the door, moisture can be prevented from flowing back into the refrigerator body.

According to the embodiment of the present invention described above, after the refrigerator compartment drainage unit 1 and the freezer compartment drainage unit 2 are integrated using the integration jig 3, the integrated assembly is attached to the refrigerator. This eliminates the need to assemble the refrigerator compartment drainage system and the freezer compartment drainage system separately, reducing the effort required for assembly. The number of members and sealing materials to be arranged can be reduced, the overall structure can be made more compact, and the problem of foaming liquid leakage can be improved.
