Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a refrigerator, in particular, to prevent the occurrence of dew condensation caused by cooling both the inner and outer boxes by a suction pipe inserted between the inner and outer boxes.

Conventionally, in this type of refrigerator, the suction pipe from the evaporator outlet to the refrigerant compressor passes through the outer box and the inner box, and is installed along the outer box or inner box, which prevents condensation from forming on the outer surface of the nearby box. Water droplets that formed and flowed down wet the refrigerator compartment, and during installation, the floor surface got wet and dirty.

For this reason, it has been considered to bury the suction pipe in the heat insulating material between the inner and outer boxes, but this requires special work to hold it in place and is complicated to manufacture.

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

Reference numeral 1 denotes a refrigerator main body composed of an inner box 2, an outer box 3, and a heat insulating material 4 filled with foam between the two boxes 2 and 3.
An evaporator 6 is disposed at a suitable location within a storage chamber 5 formed by, for example.

A refrigerant compressor 8, a condenser 9, etc., which together with the evaporator 6 constitute a refrigerant cycle, are disposed in a machine room 7 formed in the lower part of the main body 1, etc.

A suction pipe 10 from the evaporator 6 to the refrigerant compressor 8 is inserted between the inner and outer boxes 2 and 3, embedded in the heat insulating material 4, and penetrates the bottom wall 3A of the outer box 3 to the machine room 7. It is pulled inward.

Reference numeral 11 denotes a separator fitted to the outer periphery of the suction pipe 10 located in the heat insulating material 4, and is made of a heat conductive material such as a synthetic resin and is formed into a cylindrical shape or a substantially C-shaped cross section, and a radial shape. A plurality of leg pieces 12, 12, .

A continuous or discontinuous ring body 13 having a diameter larger than that of the separator 11 is integrally formed.

It is preferable that the leg pieces 12, 12 and the ring body 13 are formed at a plurality of locations on the outer periphery of the separator 11 with intervals between each other as in the embodiment. The continuous end portion 13A is disposed opposite to the circumferential opening 11A of the separator 11 to facilitate attachment and detachment of the separator 11 to the suction port 10.

Furthermore, a plurality of protrusions 14.1 are provided on the outer peripheral surface of the ring body 13.
4... are provided protrudingly spaced apart from each other on the outer periphery.

Reference numeral 15 denotes a door body that opens and closes the front opening of the storage room 5.

Since the present invention is constructed as described above, the foamed heat insulating material also penetrates between the separator, the leg pieces, and the ring body and buries them, so that the fixed position is ensured and the pulse during the flow of the refrigerant is ensured. It is possible to reduce the propagation of flowing sound, vibration, etc. to both the inner and outer boxes, and to prevent dew condensation by reliably separating the suction pipe from both the inner and outer boxes.

Furthermore, before foaming the insulation material, a suction pipe equipped with a separator is inserted between the inner and outer boxes, but even if it is deviated toward the outer box, for example, the protrusion on the ring body will not reach the outer box. In addition to holding the suction pipe at a predetermined interval and preventing dew condensation, the isolation body is made of a thermally poor conductor, and although the expansion ratio and thermal conductivity of the ring body are not O, it is possible to isolate the suction pipe from the outer box. There is almost point contact with the body etc. through the protrusions, and heat conduction to the outer box can be ignored.

Therefore, there is no need to fix and support the separator etc. to the outer box, inner box, etc. with special members in advance, and the design and manufacture can be simplified.
