Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a refrigerator having a structure in which a storage chamber is formed by an inner box and a cooler is disposed below the bottom of the inner box.

[Technical background of the invention]

Conventionally, in refrigerators, for example, the freezer compartment, which is a storage room, is formed by a relatively thick inner box (thickness: approximately 2 mm), and the area below the bottom of this inner box (for example, the freezer compartment and the Some are constructed by placing the cooler inside the partition wall between the refrigerator and the refrigerator, and foaming and filling the surrounding area with polyurethane as a heat insulating material.

[Problems with background technology]

However, in this case, even if a failure occurs in the cooler and it becomes necessary to repair or replace it, it is difficult to remove the cooler. Therefore, it is considered that the cooler can be taken out by cutting the bottom of the inner box, but the conventional inner box is relatively thick and cannot be cut easily. Even if it were possible to cut it, it would be difficult to dispose of the opening formed by the cutting, which could impair the function of the storage room.

[Purpose of invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a refrigerator in which the cooler can be easily removed without impairing the function of the storage compartment.

[Summary of the idea]

In order to achieve the above object, the present invention forms the storage chamber with a thin inner box, and in the bottom of the inner box, a plurality of slits are formed in the shape of a frame along the planar outline of the cooler located below. A separable portion having substantially the same planar shape as the cooler is formed by forming a separable portion, and a bottom plate larger than the separable portion is removably arranged on the bottom surface of the inner box. Therefore, when repairing or replacing the cooler, the removable part is separated and the cooler is taken out, and after the repair or replacement is stored, the opening formed by the separation is closed with the bottom plate. It is characterized by how it is obtained.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a refrigerator body, and 2 a freezer compartment serving as a storage room. The freezer compartment 2 is formed by a thin inner box 3 having a rectangular shape with an open front and a thickness of about 0.2 mm. Reference numeral 4 denotes a partition wall, which vertically partitions the freezer compartment 2 and the refrigerating compartment 5 below it. The bottom surface 3a of the inner box 3 of the freezer compartment 3 within this partition wall 4
A cooler storage chamber 6 is formed below, and this cooler storage chamber 6 communicates with the upper part of the freezer compartment 2 via a ventilation duct 7 provided at the back of the freezer compartment 2. It is communicated with the upper part of the refrigerator compartment 5 through a ventilation duct 8 provided at the upper rear part of the compartment 5. or,
Vent holes 9 and 10 are provided at the front of the partition wall 4 to communicate the cooler storage chamber 6 with the freezer compartment 2 and the refrigerator compartment 5, respectively. Reference numeral 11 denotes a cooler disposed in the cooler storage chamber 6, and above this a heat insulator 12 made of, for example, styrofoam is removably provided between the cooler and the bottom surface 3a of the inner box 3. . Reference numeral 13 denotes a fan installed behind the cooler 11 in the cooler storage chamber 6. When this fan is operated, the cold air inside the cooler storage chamber 6 cooled by the cooler 11 is passed through the ventilation ducts 7 and 8 to the freezer compartment. At the same time, the air in the freezer compartment 2 and the refrigerator compartment 5 is sucked into the cooler storage compartment 6 through vents 9 and 10 to circulate the air. Reference numeral 14 denotes a heat insulating material filled around the freezer compartment 2 and the refrigerator compartment 5, which is made of foamed polyurethane, for example, with the cooler 11, fan 13, etc. placed therein. On the other hand, the inner box 3 in the freezer compartment 2
As shown in FIG. 1, a plurality of slits 15 are formed in the bottom part 3a of the cooler 11 in a large frame shape along the planar outline of the cooler 11, thereby forming a cutout having substantially the same shape as the planar shape of the cooler 11. Possible part 16 (slit 1
5). In this case, the front slit 15 also serves as a vent communicating with the vent 9. 17 is a bottom plate placed on the inner bottom surface of the inner box 3, as shown in FIG. Vent hole 1 corresponds to port 9
8 is formed.

In the above configuration, when a failure or the like occurs in the cooler 11 and the cooler 11 is to be repaired or replaced, after removing the bottom plate 17,
The separable portion 16 is separated from the inner box 3 by cutting between each slit 15 with a cutter or the like, and the separable portion 16 is removed and the cooler 11 is inserted through the opening formed thereby. Take out the. In this case, the inner box 3 itself is formed to be thin with a thickness of about 0.2 mm, and a separable part 16 is formed in the bottom part 3a by a slit 15, so that the bottom part 3a is cooled. An opening for taking out the container 11 can be easily formed. In addition, after repairing or replacing the cooler 11, the bottom part 3 of the inner box 3
Although the opening remains formed in a, the inner box 3
Since the bottom plate 17 can be placed on the bottom surface 3a of the storage chamber to close the opening thereof, no problem will arise and the function as a storage chamber will not be impaired.

By the way, in the above-mentioned inner box 3, the cooler 11
In order to easily take out the material, it is conceivable to form an opening in the bottom surface portion 3a in advance for taking out the material. However, with such an inner box,
Since the inner box 3 itself is thin, its strength is further weakened, making it difficult to handle when the inner box is assembled or handled alone, and sealing work to prevent leakage when filling the insulation material 14 with foam is required. The problem arises that it becomes difficult to carry out. In this regard, according to the present embodiment, when the inner box 3 is handled, the entire bottom surface portion 3a is present, so the strength is greater than that of the above-mentioned one, making it possible to improve the handling property, and also facilitate the sealing work. When the cooler 11 is taken out, the separable part 16 is formed by the slit 15 in the bottom part 3a as described above.
Therefore, an opening can be easily formed in the bottom surface portion 3a, and the cooler 11 can be easily taken out.

[Effect of idea]

As is clear from the above description, the present invention has a storage chamber formed by a thin inner box, and a plurality of slits formed in the bottom of the inner box in a frame shape along the planar outline of the cooler located below. A separable portion having substantially the same planar shape as the cooler is formed by forming a separable portion, and a bottom plate having a larger size than the separable portion is removably arranged on the bottom surface of the inner box. Therefore, the cooler can be easily taken out without impairing the function of the storage chamber, and the inner box can be easily handled, which is an excellent effect.
