When pressure is applied downward, the arrangement of the second movement barriers 224a and 224b according to the present embodiment may be changed at regular intervals. Therefore, when the temporary assembly parts 130a and 130b are moved to the temporary assembly part 214 by the temporary assembly part guides 218 and 220, the second movement barrier 224a, 224b) may change the arrangement to the lower side. However, when the temporary assembly parts 130a and 130b are inserted into the drain pump mounting part 210, the external pressure acting on the second moving barriers 224a and 224b disappears and protrudes to the drain pump mounting plate 212, and the temporary assembly part ( It abuts against the rear surfaces 138a and 138b of 130a and 130b.

The drainage pump mounting part 210 according to the present embodiment includes a fastening part stopper 228 formed to come into contact with the fastening part 150 . When the temporary assembly parts 130a and 130b are fitted into the drain pump mounting part 210, the fastening part stopper 228 comes into contact with the front surface of the fastening part 150. The fastening part stopper 228 according to this embodiment may be formed to be continued from the central guides 218a and 218b. When the fastening part 150 comes into contact with the fastening part stopper 228, the second movement barriers 224a and 224b that limit the backward movement of the temporary assembly part protrude.

The drainage pump mounting part 210 according to the present embodiment has a fastening member hole 230 through which a fastening member fastening the fastening part 150 and the base 200 passes. The fastening member hole 230 according to the present embodiment is formed at a portion where the fastening part 150 is located when the temporary assembly parts 130a and 130b are fitted into the drainage pump mounting part 210.

The temporary assembly parts 130a and 130b according to the present embodiment can also be fastened with a separate fastening member. In this case, the temporary assembly parts 130a and 130b and the base 200 are fastened to the drainage pump mounting part 210 with a fastening member It is also possible to form a separate fastening member hole (not shown) for this.

Although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and in the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Various modifications and implementations are possible by those skilled in the art, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
