[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a machine room juxtaposed beside a heat insulating box constituting a storage room.

[0002]

2. Description of the Related Art In recent years, this type of refrigerator is mainly provided with an opening in a side wall of a heat insulating box constituting a storage room, and a heat insulating case having a built-in cooler attached from the outside of the opening. .

A conventional refrigerator is disclosed in Japanese Patent No. 252764.
Japanese Patent Application Laid-Open No. 9-No.

Hereinafter, the conventional refrigerator will be described with reference to the drawings. FIG. 6 is an overall perspective view of a conventional refrigerator, and FIG. 7 is a perspective view of a main part of the conventional refrigerator. 6 and 7, reference numeral 1 denotes a storage chamber 2 which is a heat insulating box. Reference numeral 3 denotes a machine room arranged side by side with the heat insulating box 1 and a compressor 3a, a condenser 3
b, a drawable base 4 in which a condenser blower 3c and the like are arranged is housed. Reference numeral 5 denotes a door that opens and closes the entire opening of the heat-insulating box 1. Numeral 6 denotes a heat insulating case in which a cooler 7 is housed. Further, it is attached from the outside so as to match the opening 8 provided in the side wall of the heat insulating box 1. A connecting pipe 9 connects the compressor 3a and the cooler 7. As described above, a cooling system is formed to cool the storage room 2.

[0005]

However, in the above-mentioned conventional structure, a large opening 8 is provided in the side wall of the heat insulating box 1 and the heat insulating case 6 for accommodating the cooler 7 is provided.
Because of this, there is a drawback that heat insulation with the outside becomes insufficient, which causes a decrease in cooling performance and dew condensation therearound, and that it is very difficult to draw out the cooler 7 during service. .

An object of the present invention is to solve the conventional problems, and an object of the present invention is to provide a refrigerator having improved heat insulation performance and improved drawability of a cooling system.

[0007]

According to the present invention, a compressor, a condenser, a blower for a condenser and the like are arranged in a machine room juxtaposed to a side of a heat insulating box forming a storage room. A drawable base is provided, a cooler is arranged in the heat insulating box, and an opening through which a connecting pipe connecting the compressor and the cooler is provided on the front surface of the wall, the cooler is removed, and the base is pulled out. The cooling system can be taken out,
Further, since only the connecting pipe and a few lead wires pass through the opening, the opening space is extremely small. In addition, a detachable cover pipe that closes the opening is fitted into the opening, but burring holes that form recesses are formed on the upper and lower surfaces of the opening.
And the upper and lower surfaces of the cover pipe are fitted into the burring holes.
Have a columnar protrusion that, there in the upper surface of the cylindrical projecting part
The burring hole when removing the cover pipe.
Since the abutting portion is chamfered , the cover pipe can be positioned on the same surface as the front surface of the heat insulating box by fitting the uneven portion, and the sealing performance of the door can be ensured.

DETAILED DESCRIPTION OF THE INVENTION According to the first aspect of the present invention, a machine room is juxtaposed beside a heat insulating box formed by a storage room, and a compressor, a condenser and a condenser are provided in the machine room. Provided with a drawable base in which a blower or the like is arranged, in a refrigerator in which a cooler is arranged in the heat insulating box, an opening through a connecting pipe connecting the compressor and the cooler is provided on the front surface of the heat insulating box body wall surface. Since the detachable cover pipe that closes the opening is fitted in the opening, the cooler is removed,
When the base is pulled out, the cooling system can be easily taken out, which improves serviceability. Further, since only the connecting pipe and several lead wires pass through the opening, the opening space can be extremely small, and heat leakage can be suppressed. A detachable cover pipe that closes the opening is fitted into the opening, but recesses are formed on the upper and lower surfaces of the opening .
A burring hole that, said cover pipe upper and lower surfaces Bari
Have a columnar protrusion that fits into ring bore, the cylindrical projecting part
Of the cover pipe when removing the cover pipe.
Since the portion that comes into contact with the sealing hole is chamfered, it is possible to reliably fix it at an accurate position by fitting the uneven portion.

[0009] In addition, when removing the cover pipe, circle
The fitting of the concave and convex portions can be easily released along the chamfered portions of the columnar convex portions .
