Conventional refrigerators of this type have storage compartments for storing various foods, such as a refrigerator compartment, a freezer compartment,
It also has a vegetable room and a cold room called a chilled room. By the way, in a refrigerator equipped with such various storage compartments, for example, the refrigerator compartment and the freezer compartment are equipped with interior lights to illuminate the food inside, but in this case, the mounting structure of the interior lights is It is considered a problem.

In other words, in conventional refrigerators of this type, as shown in Japanese Utility Model Publication No. 46-4394, the socket of the lamp serving as the interior light is attached to the heat insulating material of the refrigerator body. Generally, a structure was adopted in which the socket was buried inside the storage chamber and the socket was sealed and held by a partition wall on the inner box side that defined the back side of the storage chamber.

[Problem that the invention attempts to solve]

However, according to the above-mentioned conventional structure, since the lamp socket section is buried within the heat insulating material that constitutes the refrigerator main body, it is necessary to assemble the lamp socket section in advance when molding the main body heat insulating material. Not only is the molding process troublesome, but the lamp socket and lead wires are buried within this heat insulating material, and there is no room to pull out the lead wires, so the work is troublesome when replacing the lamp, especially on the lamp socket side. There were drawbacks such as the fact that maintenance due to breakdowns was virtually difficult. This is easily understood because if there is enough lead wire, etc., the lamp socket can be pulled out and repaired in the event of a failure.

In addition, in the conventional structure described above, the structure for insulating and sealing the lamp socket mounting area from the cold air flow path flowing on the back side of the storage compartment rear partition plate is complicated, and the sealing of the inner box is particularly complicated. This is a difficult situation, and it is hoped that some sort of countermeasure will be taken.

The present invention has been developed in view of the above-mentioned circumstances, and has a simple structure that makes it easy to install an interior light that is installed for internal lighting in a storage room. The object of the present invention is to obtain an inexpensive interior light mounting structure for a refrigerator that can be repaired and is excellent in sealing properties of an inner box, etc., ease of assembling each part, etc.

The indoor light mounting structure for a refrigerator according to the present invention is equipped with a back partition plate that forms a cold air air path on the back side of the storage compartment, and heat insulation is provided at a position corresponding to the lamp installation part on the back side of the back partition plate. A sealed space surrounded by a wall made of wood is formed, and an opening for installing a lamp is bored in the part of the rear partition plate corresponding to this sealed space, and a part of the side edge of this opening is provided with a partition plate. A lamp mounting piece protruding from the back side is integrally provided, and a notch in which a lamp socket portion is attached and held is formed in this mounting piece.

[Effect]

According to the present invention, the lamp is integrally attached to the back partition plate of the storage room, and is thermally isolated from the cold air path on the back side of the partition plate.

〔Example〕

Hereinafter, the present invention will be explained in detail using an embodiment shown in the drawings. Figures 1 to 5 show an embodiment of the interior light mounting structure for a refrigerator according to the present invention. First, the overall schematic structure will be briefly explained using FIGS. 4 and 5. In the figure, reference numeral 1 is the refrigerator main body, and this main body 1 consists of an outer box 2, an inner box 3, and a container filled between them. The inner box 3 is made up of an outer box insulating material 4, and its back side is partitioned by a back partition plate 5 within the inner box 3 described above, so that a storage chamber 6 such as a freezer compartment is formed in the front part of the partition plate 5. On the other hand, a cooling chamber having a cooler 8, a cooling fan 9, cold air supply side air passages 11a, 11b, etc. is formed on the back side thereof. In the figure, numeral 7 denotes a cold air outlet opened at the upper part of the rear partition plate 5, and numeral 10 denotes a heat insulating material attached to the cooling chamber side of the partition plate 5.

Now, according to the present invention, as is clear from FIGS. 1 and 2, a rear partition plate that forms a cooling chamber with a cold air supply side air passage and the like on the rear side of the storage chamber 6 as described above. A sealed space surrounded by a wall made of heat insulating material 10 is formed at a position corresponding to the lamp mounting part 12 on the back side of the lamp 5, and a lamp mounting opening 13 is formed in the rear partition plate 5 corresponding to this sealed space. A lamp mounting piece 15 is integrally provided on a part of the side edge of this opening 13 and projects toward the back side of the partition plate, and a notch 15a is formed in this mounting piece 15 to which the lamp socket portion 14a of the lamp 14 is mounted. It has characteristics in that way.

Here, in this embodiment, a case is shown in which the lamp mounting portion 12 is provided on an inclined surface portion formed by bending the partition plate 5 at a predetermined point to the rear side,
Further, in FIG. 3, 14b is a lead wire drawn out from the socket portion 14a of the lamp 14, and 16 is a locking hole formed on the side edge of the lamp mounting opening 13 on the side of the storage chamber 6 so as to cover the opening 13. 17a, 17
This is a lamp cover that can be detachably attached via b.

According to the indoor light mounting structure for a refrigerator according to the present invention having the above-mentioned structure, the lamp socket mounting portion 12 is directly provided on the back partition plate 5 of the storage compartment 6, which makes the structure simple. First, the heat insulating material 10 attached to the back side of the partition plate 5 not only easily and reliably seals the cold air supply side air passage of the lamp mounting part 12 and the cooling chamber side, but also seals the lamp socket part of the lamp 14 easily and reliably. 14
Since it can be installed or removed using a simple attachment/detachment operation, it is extremely easy to perform tasks such as replacing the lamp 14 and maintaining the lamp socket part 14a, especially since the lead wire 14b has plenty of room to draw out. This has the advantage that the lamp socket portion 14a can be pulled out to the outside of the refrigerator for repair.

Here, in the lamp mounting part 12 mentioned above,
The lamp 1 is a sealed space defined by the heat insulating material 10 that defines its surroundings from the cooling side such as the cold air supply side air passage.
It is preferable to form it with a certain amount of margin to allow heat generation at 4.
