Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a refrigerator, and in particular, the lead wires leading into the main body are better supported than the electrical components inside the inner box.

Conventionally, in this type of refrigerator, the lead wires from the defrosting heater and temperature controller of the cooler built into the inner box are drawn out to the machine room formed at the bottom of the main body outside the outer box, where the power supply, electrical components, etc. However, it is troublesome to pass through the outer box on each side of each lead wire and pull them out, and the tying work is complicated to bundle and pull out all the lead wires. The foam insulation material easily leaked through the through holes drilled in the outer box, making sealing work complicated.

This proposal was developed in view of the above points, and the figures will be explained below.

Reference numeral 1 denotes a refrigerator main body composed of an outer box 2, an inner box 3, and a heat insulating material 4 filled with foam between the two boxes 2 and 3, with the inside of the inner box 3 opened to the front by a partition wall 5. -L lower two wheels 6 and 7 are partitioned.

A cooler 8 for cooling the two units, the -1 part freezer compartment 6 and the lower refrigerator compartment 7, is installed at a suitable location within the partition wall 5, and the cold air cooled by the cooler 8 is circulated by a circulation fan 9. are supplied and circulated to chambers 6, 7-\- in the above-mentioned -.

Dew water dripping from the cooler 8 during defrosting, etc., is received and collected in a dew pan 10 formed on the upper surface of the lower member 5A of the partition wall 5. The water is then discharged through a drain pipe 12 to an evaporating dish 14 in a machine room 13 formed at the bottom of the main body 1.

The drain pipes 12 are disposed vertically along the back wall 31 of the inner box 3, protruding outward and extending in the extension direction. A plurality of adjacent and opposing clamping pieces 15j5 are integrally formed.

The clamping piece i5.15 has elasticity, and has protrusions 16, 16 formed in the vicinity of each free end that bulge in the mutually approaching direction, and has an opening width of the support groove 17 formed between the phases n. It's narrowing.

18° 18... is a defrosting heater (not shown) attached to the cooler 8, a circulation fan 9, or an inner box 3
Lead wires are connected to various devices such as temperature controllers installed at appropriate locations inside and outside, and are located between the outer box 2 and the inner box 3. Those from inside the inner box 3 are connected to the through holes 19 drilled at appropriate locations. Pull outward,

derived within.

The drain pipe 12 may be supported in one place or in multiple places on the back wall 3A of the inner box 3 or on the inner surface of the back wall 2B of the outer box 2 with adhesive tape or the like.

In the case of only one clamping piece 15, as shown in FIG. This operation is performed on the inner box 3 or the outer box 2 to form the support groove 17'.

The front openings of the freezer compartment 6 and the refrigerator compartment 7 are formed by door bodies 18 and 1.
9, each is closed so as to be openable and closable.

Reference numeral 20 denotes a cup-shaped stand that is removably placed in a door storage section 21 formed on the inner surface of the door body 19, and a cylindrical support section 23 that expands upward is mounted on a flat base 22. 24 containers for mayonnaise, ketchup, etc.
It is inserted and supported so that it can be freely delivered in an inverted state.
A through hole 25 is formed in the base 22 as necessary so as to communicate with the inside of the support part 23.

Furthermore, if a handle 26 is formed on the outside of the support portion 23, it will be convenient to carry.

As described above, in this case, a clamping piece is formed on the drain pipe that discharges dew water from a cooler, etc., and the lead wire is tied and supported by this clamping piece, and the lead wire is passed through the outer box together with the drain pipe. Because it is pulled out, the lead wire can be bundled and supported at the same time as supporting the drain pipe, which simplifies the process.The clamping piece protects the lead wire from contact with other objects and damage to the lead wire during production. There will be fewer things.

Furthermore, since the lead wire is pulled out of the outer box together with the drain pipe,
There is no need for through holes in the outer box for drain pipes and lead wires, and the through holes for the drain pipes can be used in common, simplifying manufacturing work and sealing points to prevent leakage of insulation material. You can do less.

If the drain pipe and the lead wire are made to pass through the bottom wall of the outer box, there will be almost no problem with the external appearance even if the foam insulation material leaks out to some extent.
