Description

[Detailed description of the invention] This invention utilizes the through-hole for suction pipe insertion provided in the inner box that constitutes the heat insulating wall of the refrigerator body to insert the wiring cords of various electrical components. This invention relates to a refrigerator whose purpose is to reduce manufacturing costs without separately providing a through hole for a wiring cord in an inner box.

A detailed explanation will be given below using an example shown in the drawings.
1 is a refrigerator body made by injecting and foaming a foamed heat insulating material 4 between an inner box 2 made of synthetic resin and an outer box 3 made of metal, and partitioned into two upper and lower chambers by a heat insulating partition wall 5;
The upper part is a freezer compartment 6, and the lower part is a freezer compartment 7, and a partition plate 9 for forming a cooler storage compartment 8 is attached to the rear rear of the freezer compartment 6.

A discharge port 10 for discharging cold air is provided in the upper part of the partition plate 9, and a suction port 11 for sucking in the cold air is provided in the lower part thereof.The discharge port 10 is driven by a motor 12. A blower fan 13 is attached. 14 is the cooler storage chamber 8
The cold air cooled by the cooler 14 is fed into the freezer compartment 6 from the discharge port 10 by the drive of the blower fan 13, where it cools the stored items, and then passes through the suction port. 11 into the cooler storage chamber 8.

A portion of the cold air from the cooler 14 is sent into the refrigerator compartment 7 through a cold air duct (not shown), where it cools the stored items and then passes through an inlet provided at the rear of the heat insulating partition wall 5. It is designed to be returned to the cooler storage chamber 8 through 15.

Numeral 16 is a suction pipe for connecting the cooler 14 and the compressor 17 provided at the rear bottom of the refrigerator body 1, and is embedded in the foam insulation layer 4 through a through hole 18 drilled in the inner box 2. has been done. The through hole 18 is connected to the suction pipe 16.
The hole diameter is sufficiently larger than the diameter of the suction pipe 16, and a closing member 17 for positioning and positioning is attached above the suction pipe 16. This closing member 17 has a semicircular shape, and an engagement groove 19 that engages with the outer circumferential edge of the through hole 18 is formed at its outer peripheral edge. The closing member 17 is integrally molded with the wiring cords 20, 20, etc. of various electrical components, and the closing member 17 is inserted into the through hole 18 of the inner box 2.
The wiring cords 20, 20, . . . are buried in the foam insulation layer 4 together with the suction pipe 16. Note that 21 is a sealing material for sealing the surplus space of the through hole 18.

Therefore, when assembling the refrigerator body 1 of the present invention, first, the outer box 3 is assembled to form an appropriate space around the outer periphery of the inner box 2, and the through hole 1 of the inner box 2 is assembled.
A suction pipe 16 is inserted into the inner box 8 and the suction pipe 16 is positioned in the space between the inner box 2 and the outer box 3.

Next, the wiring cords 20, 20, . At the same time,
The closing member 17 is inserted into the through hole 1 using its engagement groove 19.
Attach it to the top of 8. At this time, the closing member 1
The lower end of the suction pipe 7 presses the upper edge of the suction pipe 16 downward to prevent the suction pipe 16 from wobbling and to position it at a predetermined position.

Therefore, the extra space of the through hole 18 that cannot be closed by the closing member 17 alone is filled with a sealing material 21 to prevent leakage of the insulation material, and then the inner box 2 and the outer box 3 are closed.
The foamed heat insulating material 4 may be injected and foamed into the space formed by the above.

The present invention provides a refrigerator in which a foamed heat insulating material is injected and foamed between an inner box and an outer box, and a suction pipe is buried in the foamed heat insulating material layer, and a through hole is provided in the inner box. The above-mentioned suction pipe is inserted into this through hole, and a wiring cord of an electrical component integrally molded with a positioning/closing member having an engagement groove is inserted into the surplus space, and the positioning/closing member and the sealing material are inserted into the surplus space. Since the surplus space of the through hole is closed and the suction pipe and the wiring cord are buried in the foam insulation layer, the through hole for inserting the suction pipe into the inner box and There is no need to provide a separate through-hole for the wiring cord to pass through, and the suction pipe and wiring cord can be buried in the foam insulation layer using a common through-hole, resulting in an extremely simple structure, low cost, and workability. In addition to this, the closing part provided on the wiring cord allows the suction pipe to be positioned without moving up or down, which prevents the wiring cord coating from tearing or breaking due to burrs around the through-hole. This can bring about many remarkable effects, such as completely eliminating such problems.
