Reference numeral 64 denotes a first protruding surface protruding from the right side of the mounting surface 62. A transformer 66 and a capacitor 68 for compressor movement are mounted on the first protruding surface 64. In addition, the above-mentioned drawer member 22 is arranged so as to be located above the first projecting surface 64.

Reference numeral 70 denotes a second protruding surface that protrudes from the left side of the mounting surface 62. A capacitor 72 for starting the compressor is mounted on the second protruding surface 70.

Reference numeral 74 denotes a roof member provided on the upper right side of the mounting surface 62. The roof member 74 is configured to cover the right side of the mounting surface 62, as shown in FIGS.

Reference numeral 76 denotes a lower surface projecting portion projecting obliquely forward from the lower surface of the mounting surface 62.

Reference numeral 78 denotes a fixing portion for fixing the lead wire 48 provided on the roof member 74 by cutting and raising.

Reference numeral 80 denotes a fixing portion of the lead wire 48 similarly provided on the right side of the mounting surface 62 by cutting and raising.

Reference numerals 82 and 84 denote fixing portions of the lead wires 48 provided by cutting and raising the lower surface projecting portions 76.

Reference numeral 86 denotes a fixing portion for the lead wire 48 provided by cutting and raising on the left side of the mounting surface 62.

Reference numerals 88 to 92 denote claw portions provided on the inner peripheral portion of the mounting surface 62 for fixing the control plate 10.

Reference numeral 94 denotes a rib provided on the inner surface of the mounting surface 62 for positioning the control plate 10.

The mounting member 60 having the above structure is integrally formed of a synthetic resin.

A case where the control plate 10 is mounted using the mounting member 60 will be described.

First, as described above, the lead wire 48 is drawn from the lead member 22.

As shown in FIG. 8, the mounting member 60
Is screwed to the arrangement surface 16.

The transformer 66 and the capacitors 68 and 72 are mounted on the first protruding surface 64 and the second protruding surface 70, respectively.

The control plate 10 is mounted on the mounting surface 60. In this case, the control plate 10 is positioned by the rib 94 and is fixed by the claw portions 88, 90, 92. Further, screwing is performed.

The lead wires drawn out from the lead member 22 are fixed to the peripheral portion of the mounting surface 62 by fixing portions 78 to 86, respectively, and the lead wires 48 are wired as shown in FIG.

When the mounting member 60 is used as described above, the control plate 10 can be easily and securely mounted, and the wiring of the lead wires 48 can be efficiently simplified.

Since a roof member 74 is provided above the mounting surface 62, the water flowing along the outer box 14 flows along the back side of the mounting member 60 by the roof member 74 as shown in FIG. No water flows on the control plate 10 due to the flow.

Further, as shown in FIG.
When the cover 13 is put on the cover 13, the roof member 74 is arranged inside the cover 13. Therefore, even if an object hits the cover 13, the roof member 74 can prevent the cover 13 from being dented.

When the control plate 10 is mounted on the mounting surface 60, the claws 88 can be bent outward by putting a hand on the roof member 74, and the roof member 74 also serves as a handle. For this reason, workability of the work of attaching the control plate 10 is improved.

[0066]

As described above, according to the lead wire drawing member of the refrigerator of the present invention, since the lead wire is drawn through the first insertion hole and the second insertion hole, the lead wire is formed at the edge of the through hole provided on the wall surface. It will not hurt you.

Since the lead wire can be inserted into the lid through the notch in the second insertion hole, the workability is improved.

According to the lead wire drawing member of the refrigerator of the second aspect, by providing the claw, the lid portion and the fitting portion can be completely engaged.

According to the third aspect of the present invention, the adhesive tape for winding the lead wire is compressed by the peripheral portion of the second insertion hole, so that the through hole is sealed and attached to the refrigerator main body. The sealing property of the injected urethane is improved. Further, since the adhesive tape is compressed, it does not come close to the charged part of the electrical component.
