Description

[Detailed description of the invention] The present invention relates to a refrigerator with an improved mounting structure for attaching a high-pressure side refrigerant pipe to the inner surface of an outer box.The purpose of the invention is to provide a refrigerator that can reduce the number of parts and contribute to cost reduction. It is in.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a heat insulating casing comprising a heat insulating material 4 enclosed between an inner box 2 and an outer box 3, which forms a freezer 5 and a refrigerating chamber 6 inside. Reference numeral 7 denotes a steel bottom plate installed and fixed at a predetermined distance below the heat insulating casing 1, and forms a space 8 between the outer bottom surface of the outer box 3 and the bottom plate 7. 9 is a compressor installed in the rear part of the space 7, and 10 is a condenser pipe as a high-pressure side refrigerant pipe led out from the discharge side of the compressor 9, and a part of this (the part on the compressor 9 side) is bent in a meandering shape. The remaining part (the part on the cooler side) is attached to the flange part 3a of the opening edge of the outer box 3 closed by the back plate 1a, and the final part is Eventually, it will be led to the cooler for the refrigerator room. Reference numeral 11 designates a receiving plate for an evaporation plate 12 provided on a meandering condenser pipe 10. When the compressor 9 is operated, the compression heat of the compressor 9 generates an updraft that rises along the back surface of the heat insulating casing 1, and this updraft flows into the space 8 from the front to the rear. An air current is generated and the condenser pipe 10 is cooled.

Now, reference numeral 13 denotes two fixing tongue pieces for fixing the condenser pipe 10 to the heat insulating case 1, and as shown in FIG.
A notch is cut out in the shape of a letter, and the remaining two opposing pieces are bent downward by cutting and raising, and one side end surface 13a of these two tongue pieces 13 is engaged with the condenser pipe 10, and the condenser pipe 10 is turned into a tongue. It is held between one end surface 13a of the piece 13 and the inner surface of the flange 3a of the outer box 3. Reference numeral 14 denotes a tape attached to the outer box 3 in order to close the through hole 15 created when the tongue piece 13 is cut and formed. The heat insulating material 4 is prevented from leaking to the outside from the through hole 15. Reference numeral 16 denotes a table mounted on the upper surface of the heat insulating case 1, whereby the tape 14 that closes the through hole 15 is hidden and not exposed to the outside, improving the appearance.

According to the above configuration, the tongue piece 13 is formed by cutting and bending on the outer box 3, and the capacitor pipe 10 is fixed by the end face 13a on one side of the tongue piece 13, so that a fixing member of a separate member can be attached to the outer box. Unlike fixing the capacitor pipe by welding, the number of parts can be reduced and costs can be reduced, and unlike fixing the fixture by welding, the tongue piece 13 can be bent. All you have to do is
The workability of attaching the capacitor pipe 10 can be improved. Furthermore, since the condenser pipe 10 is locked and fixed between the one side end surface 13a of the tongue piece 13 and the inner surface of the flange portion 3a of the outer box 3, the outer box 3
Even if the thickness of the capacitor pipe 10 is small, if the tongue piece 13 is formed to be wider than the thickness, the tongue piece 13 will have a thick wall in the direction of the external force received from the condenser pipe 10, and will have high rigidity. , it is possible to obtain a large fixing force, and therefore the tongue piece 13 can be firmly locked to the condenser pipe 10, and the condenser pipe 10 can be firmly fixed.
can be securely fixed.

Note that the location where the tongue piece 13 is cut and formed is not limited to the top surface of the outer box 3 as in the above embodiment, but may be formed on both left and right sides of the rear end of the outer box 3 or on the back plate that covers the rear opening of the outer box 3. Both the left and right outer peripheral edges of 1a may be used. In particular, when the tongue piece 13 is formed on the back plate 1a as described in the latter case, when the heat insulating material 4 is enclosed, the through hole may be used as the hole for enclosing the heat insulating material 4. Available. Further, the capacitor pipe 10 is not limited to the one provided at the flange portion 3a that forms the opening edge of the outer box 3 and to which the back plate 1a is attached, as in the above embodiment, but is provided at the front opening edge of the outer box 3. With this configuration, even if hot and humid air comes into contact with the front opening edge of the outer box 3 when the refrigerator door is opened or closed, the heat from the condenser pipe 10 will cause the outer box to Condensation on the front opening edge of No. 3 can be suppressed.

As explained above, in the present invention, when fixing the high-pressure side refrigerant pipe to the heat-insulating casing, by providing a tongue piece by cutting and forming the outer box, it is possible to fix the high-pressure side refrigerant pipe using a separate member. In addition to eliminating the need for tools and contributing to cost reduction, the simple operation of simply bending the tongue piece improves the workability of installing the high-pressure side refrigerant pipe. Since the high-pressure refrigerant pipe is locked and fixed between the side end face and the inner surface of the flange part of the outer box or the front opening edge, the required strength of the tongue piece can be maintained even when the outer box is thin. is obtained,
It is possible to provide a refrigerator in which a high-pressure side refrigerant pipe can be securely fixed.
