Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a refrigerator in which a part of a refrigerant pipe on the heat radiation side of a refrigerating cycle unit is provided on the front surface of a partition wall portion such as a freezing compartment and a refrigerating compartment to prevent dew formation in the vicinity thereof. .

[0002]

[Prior art]

 Conventionally, a refrigerator of this type is apparent from, for example, Japanese Utility Model Laid-Open No. 63-49481, and the description of the Japanese Utility Model Laid-Open No. 63-49481 will be given below with reference to FIG.

Reference numeral 21 is an outer box of the refrigerator, 22 is an inner box, and 23 is a foamed polyurethane filled between the outer box 21 and the inner box 22. Reference numeral 24 is a partition that partitions the inside of the refrigerator, 25 is an upper partition plate that constitutes the partition 24, and 26 is a lower partition plate.

Reference numeral 27 is a heat insulating member disposed between the upper partition plate 25 and the lower partition plate 26, and at the same time constitutes an air passage 28 for returning the cool air in the refrigerating chamber to a cooler (not shown).

Reference numeral 29 is a pressing member such as polystyrene foam disposed in the front opening formed by the upper partition plate 25 and the lower partition plate 26, and 30 is a front surface of the pressing member 29 for preventing dew condensation. This is the condenser pipe. Reference numeral 31 denotes a front plate of the front partition which constitutes the front surface of the front partition 24, and 32 denotes a good heat conductor which is in close contact with the back surface of the front plate 31 of the front partition and the condenser pipe 30.

With the above structure, the heat from the condenser pipe 30 is transferred to the front partition plate 31 to prevent dew condensation.

[0007]

[Problems to be solved by the device]

 However, in these configurations, the number of parts is large in order to secure the space for ensuring the close contact between the pressing member 29, the good thermal conductor 32, and the front partition plate 31 and the pressing member 29 in order to prevent dew condensation. It was troublesome to improve the dimensional accuracy during assembly.

In consideration of the above problems, the present invention provides a refrigerating cabinet with a reduced number of parts and improved workability.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the refrigerator of the present invention comprises a condenser pipe arranged in front of a partition for partitioning an inner box and a compartment into a plurality of chambers, upper and lower partition plates constituting the partition, and the partition described above. It consists of a heat insulating member with air passages arranged between the plates, a front partition plate, and polyurethane foam filled between the outer and inner boxes.The heat insulating member is located at the rear of the condenser pipe contact surface and the partition plate. It is characterized in that it has a cavity consisting of, and this cavity communicates with a space constituted by an outer box and an inner box through perforations arranged in the inner box at both ends thereof.

[0010]

[Action]

 With the above-mentioned configuration, without having a separate supporting member for supporting the condenser pipe, and due to the filling pressure of the polyurethane foam to be filled into the heat insulating member side, the above-mentioned middle partition front plate, the condensing pipe and the heat insulating member are provided. Adhesion of members can be secured, and good heat conductors and pressing members can be deleted.

【Example】

 A refrigerator according to an embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 1a, an inner box 1b, and a foamed polyurethane 1c filled between both boxes. Reference numeral 2 is a partition which divides the refrigerator body 1 into upper and lower parts. Reference numerals 3 and 4 denote upper partition plates and lower partition plates constituting the partition 2, and 5 denotes a heat insulating member located between the upper and lower partition plates 3 and 4.

An air passage 6 is formed in the heat insulating member 5 to guide cold air in the refrigerating chamber to a cooler (not shown).

Reference numeral 7 denotes a hollow formed in a tubular shape by the heat insulating member 5 and the lower partition plate 4, and both ends thereof face the inner box 16. Reference numeral 8 denotes an inner box perforation 8 arranged at a position facing both ends of the cavity 7, and the cavity 7 communicates with the foamed polyurethane 1c through the inner box perforation 8. Reference numeral 9 denotes a condenser pipe arranged on the front surface of the partition 2, the rear portion of which is in contact with the heat insulating member 5 and the front portion of which is in contact with the front partition plate 10.

Therefore, the polyurethane foam 1c also flows into the cavity through the inner box perforation 8 and presses the heat insulating member 5 toward the condensation pipe 9 to bring the front partition plate 10 into contact with the condensation pipe 9. Is.

As a result, even if the number of parts is reduced as compared with the conventional case, the front partition plate 10 and the compression pipe 9 can be brought into close contact with each other to prevent dew condensation.

Further, workability is improved by reducing the number of parts.

[0018]

[Effect of device]

 As described above, according to the present invention, by filling the cavity located at the rear of the condenser pipe with polyurethane, the adhesion pressure between the condenser pipe and the front partition plate can be improved by the filling pressure, and for the purpose of heat conduction. No heat conductors or pressing members are required, and the number of parts and work processes can be reduced.
