Description

DETAILED DESCRIPTION OF THE INVENTION [Utilization of the invention flr] The present invention relates to an invention for efficiently making a heat generating portion of a radiant type straightening pipe heater arranged to perform cooling of a cooler.

[Background of the invention]

If you look at the conventional refrigerator with this ridge structure in Figures 6 and 7, 1 is the main unit of the refrigerator, 2.3 is the freezer compartment formed inside the cold air cabinet body 1, It is cold and dignified. 4 is a partition wall that separates the freezer compartment 2 from the cold storage compartment M3. 51"t shows a cold air passage formed in the partition wall 4. 6 is a cooler installed at the rear of the freezer compartment 2. 7 is a radiant defrosting unit installed at the bottom of the cooler 6. This is a tube heater. 8 is a rubber cap attached to both ends of the silk removing heater 7, which processes the ends of the reeds (not shown). 9 is a cooler 6 and a box removing heater 7. It is a ceiling cover installed between the tube heaters 7.

This ceiling cover 9 is γ southward from the cooler 6.
i This prevents water from hitting the defrosting tube heater 7 and generating evaporation noise. Moreover, this ceiling cover 9 is attached to a pipe heater 7111 for removing silk by holding the mounting legs 9a at both ends! In addition to being attached to the rubber cap 8 of 1, it is suspended from the cooler 6 with support legs 9b. Reference numeral 10 denotes a gutter that receives the removed water flowing south from the cooler 6.

This gutter 10 is used when the foam insulation material is installed in the refrigerator body 1 as shown in the figure. 11 is a protective body made of aluminum or the like. This limb protection body 11 prevents the gutter 10 from being abnormally heated and deformed by the lightning heater 7 for removing waste. Reference numeral 12 denotes a drain provided to drain the unboxed water collected in the gutter 10 to the outside of the refrigerator. The cold air passage 5 shown in the figure (the cold air discharged into the refrigerator compartment 3 is passed through the cooler 6)
For the purpose of preventing frost from forming inside the passageway returning to the
! 1. It is always installed opposite to this cold air S path 5.

1311, a partition that divides the inside of the refrigeration volume 2 into a place where the cooler 6 is installed and a place where the eutectic is placed, 14 is a fan guard, 15 is a blower for forced circulation of cold air, such a configuration In a refrigerator having a conventional structure, the cooling operation of gourds is carried out as follows. After drying up, the cold air cooled by the cooler 6 is discharged into the refrigeration volume 2 by the blower 15 for indoor circulation through the partition 13 and fan guard 14, and also into the cold air chamber 3. Although not shown, the cold air is discharged through path A.

The cold air discharged into the freezer compartment 2 and refrigerator 3 cools the food in each compartment, and then returns to the cooler 6 section. That is, the cold air in the freezer compartment 2 returns through the freezer compartment return cold air passage 16, and the cold air in the refrigerator compartment returns through the cold air passage 5. While this operation is repeated, a sheath forms on the cooler 6. When the defrosting lightning heater 7 is passed through to remove the accumulated frost, the cold air around the defrosting tube heater is transferred to the heater 7. +#Iσ
The water rises to the cooler 6 side and melts the frost that has formed on the cooler 6. In this process, the melted water falls from the cooler 6 toward the cooling heater 7. However, since there is a ceiling cover 9 above the defrosting pipe heater 7, the box removal water of the direct light does not hit the defrosting pipe heater 7 and generate evaporation noise. Furthermore, when the defrosting tube heater 7 is heating, the surface of the gutter 10 is covered with the aluminum protector 11, so that the gutter 10 will not be abnormally heated and deformed.

As described above, conventional refrigerators have been made practical by providing the protector 11 that covers the entire gutter 10, but the cost of the protector that covers the entire gutter 1o is high, and the cooler 6, ceiling cover 9, pipe heater for pouring silk 7
In the refrigerator in which the refrigerator 6 is attached, the fan guard 14 and the partition plate 13 are removed and the cooler 6 is pulled out to the freezer compartment 2 side. When servicing the cooler 6, a problem frequently occurred in which the relief heater 7 hit the part 2 of the partition wall 4 and the cooler 6 could not be pulled out.

Furthermore, since no special measures have been taken to supply heat from the phase removal heater 7 to the cold air passage 5 which cannot be covered with the aluminum protector 11, the heat supply from the phase removal heater 7 is excluded. If the heat supply from the cold air passageway 5 was too large, the heat insulating material of the partition wall 4 forming the cold air passage 5 would be thermally deformed.

[Purpose of the invention]

The present invention is an attempt to solve the problems of the above-mentioned shields.

[Summary of the invention]

That is, the heat generating part of the defrosting tube heater is located in a box-shaped cover with an open top, and the top surface of the defrosting tube heater is covered with a ceiling cover, and is surrounded by the box-shaped cover and the ceiling cover. The heating section layer (the room where the heat generating section of the waste removal pipe heater is located) can be placed in the gutter installed at the bottom of the cooler, and the bottom of the heating chamber can also be equipped with an air intake port to take in the cold air returned from inside the refrigerator. It forms an air outlet for introducing hot rays and heated air toward the cooler, etc., and the rising piece on the side opposite to the partition wall of the box-shaped cover is formed perpendicular to the bottom surface of the box-shaped cover. be.
