Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is directed to the installation location of a radiation-type defrosting pipe heater provided to remove frost adhering to a cooler or a refrigerating room suction passage. It is related to.

[Prior art]

In this type of conventional radiation type defrosting pipe heater, a heater 12 is fixed using a part of a heater cover provided at the lower part of a cooler 8, as shown in FIG.

This heater cover 13 is designed to cover the entire width of the cooler 8, and the dew melted by the defrosting tube heater falls from the cooler and hits the defrosting tube heater, causing evaporation noise. It has become. This heater cover had a defect in that the diagonal line part 5C (styrofoam) of the partition part 5 that separates the freezer compartment 6 and the refrigerator compartment 7 was heated to too high a temperature by the defrosting tube heel and was melted and deformed. In addition, because the defrosting pipe heater was installed at an intermediate position between the freezer compartment suction passage and the refrigerator compartment suction passage, the radiant heat from the defrosting pipe heater did not reach the refrigerator compartment suction passage, resulting in residual frost. There was a drawback.

[Purpose of the invention]

An object of the present invention is to efficiently defrost the inside of a refrigerator compartment suction passage using the radiant heat of a defrosting pipe heater.

[Summary of the invention]

Between the freezer compartment and the refrigerator compartment, the refrigerator compartment 5 is more humid, so frost is more likely to form inside the refrigerator compartment suction passage. Therefore, we installed the defrosting pipe heater horizontally with the refrigerator compartment suction passage, and since the partition would melt if left as is, we created a structure in which the bulk of the heater cover on the 5 partition side was extended, avoiding the refrigerator compartment suction passage. It is intended to be provided.

[Embodiments of the invention]

The details of the present invention will be explained below using an example shown in the drawings.
Reference numeral 1 denotes a refrigerator body, which is constructed by filling a foamed heat insulating material 4 between an outer box 2 and an inner box 3. Reference numeral 5 denotes a partition, which partitions the upper part of the inner box 3 into a freezing compartment 6 and the lower part into a refrigerating compartment 7. Reference numeral 8 denotes a cooler, which is installed in a cooler chamber lo formed by a cooling chamber partition plate 9 provided at the back of the freezing chamber 6. In the freezer compartment suction passage 5a, cold air forcibly sent out by the fan IJ circulates through the freezer compartment 6, is sucked into the freezer compartment suction passage 5a, and returns to the cooler 8. Similarly, in the refrigerator compartment suction passage 5b, part of the cold air forcibly sent out by the fan 11 enters the refrigerator compartment 7 and circulates through the refrigerator compartment suction passage 5.
b and returns to the cooler 8. Reference numeral 12 denotes a radiation-type defrosting pipe heater, which is attached to the side plate of the cooler 8 using a part of the heater cover. This defrosting pipe heater 12 is placed in a horizontal position with respect to the refrigerator compartment suction passage 51, as shown in FIG. In addition, the heater cover was made long because if it was too short, the partition would melt, but the radiant heat of the defrosting tube heater would not reach the refrigerator compartment suction passage, resulting in residual frost. As shown, it is cut out facing the refrigerator compartment suction passage.

Therefore, as described above, it becomes easy to defrost the back of the 5th refrigerating room suction passage 5b, and there is no need to worry about melting the partition 5C.

〔Effect of the invention〕

As explained above, the present invention installs a defrosting tube heater horizontally with the suction passage of the refrigerator room, which is difficult to defrost, and extends the bulk of the heater cover on the partition side to prevent the partition from melting. Since there was a cut in the same shape as the indoor suction passage, radiant heat can reach deeper into the refrigerator suction passage. Therefore, the radiant heat of the defrosting tube heater can be used efficiently.

Claims (1)

[Scope of Claims] 1. A suction port for returning cold air from the refrigerator compartment to the cooler room is formed in the compartment insulation wall filled in the partition wall that partitions the freezer compartment and the refrigerator compartment, and the compartment insulation wall In addition to forming a gutter in the defrosting water receiver of the cooler, a radiant defrosting tube heater is installed at the bottom of the cooler. A refrigerator characterized by being installed at a position substantially horizontal to a suction passage opening. 2. A heater cover attached to the top of the defrosting pipe heater covers the partition wall side of the pipe heater, excluding the part facing the refrigerator compartment suction passage, so that the pipe heater directly irradiates the inside of the suction passage. A refrigerator according to claim 1, characterized in that:
