Description

[Detailed description of the invention] This invention relates to the configuration of a refrigerator in which either the freezer compartment or the refrigerator compartment is in a vertical position, with either the upper compartment being the upper compartment, and a special storage structure that makes it easy to replace the blower. In addition, the present invention provides a refrigerator having a structure in which defrosting water of the cooler does not flow down to the suction port of the blower and freeze, and which does not reduce the internal volumes of the freezer compartment and the refrigerator compartment.

Next, embodiments of the present invention will be described in detail based on the drawings.

Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3, and a foamable heat insulating material 4 such as polyurethane foam filled in the space between these two boxes by an in-situ foaming method.

The inner box 3 is made of synthetic resin or the like, with a freezer compartment part 3a, a refrigerator compartment part 3C, and a partition wall part 3b that partitions these two compartments integrally formed by vacuum forming or the like. It serves as a mounting surface for the cooler 25, that is, a dew receiving surface, and is sloped low toward the drain port 5.

The inner box 3 has a shape in which a groove is formed on the back surface of the partition wall portion 3b and is open to the rear and both left and right sides, and the groove of the partition wall portion 3b is also filled with a heat insulating material 4 to create a heat insulating partition wall. 15 is formed.

A notch hole 8 is formed at the rear end corner of the central portion of the upper surface of the partition wall portion 3b, extending from the lower side of the back wall of the freezer compartment portion 3a to the earthen wall of the partition wall portion 3b.

This hole 8 forms a part of the cold air passage and the blower 11
This is provided to facilitate the attachment and detachment of the

Reference numeral 6 denotes a duct member which faces the notch hole 8 and extends from the freezer compartment portion 3a to the refrigerator compartment portion 3C on the back side of the inner box 3.
Cold air discharge ports 18 and 1 formed in a and refrigerator compartment portion 3C, respectively.
A cold air passage 20 communicating with the inner box 3 is formed between the inner box 3 and the inner box 3.

A duct auxiliary member 9 is attached to the inner box 3 together with the duct member 6 so as to be located between the inner box 3 and the duct member 6 so as to face the notch hole 8 .

This duct auxiliary member 9 is located below the cutout hole 8 and extends inside the earthen wall and the lower wall of the partition wall section 3b at the rear thereof so as to form a recess 10 opening into the hole 8 in the partition wall section 3b. box 3
The cold air passage 20 is combined with the duct member 6 so as to be sealed independently from the space between the outer box 2 and the outer box 2, and the heat insulating material 4 is prevented from entering into the cold air passage 20.

Therefore, the duct auxiliary member 9 is located at the thickest part of the heat insulating partition wall 15.

The duct member 6 is formed with a recess 6A that bulges rearward in correspondence with the notch hole 8 and the recess 10, and is a portion that accommodates the electric motor 11 of the blower 11.

The main body 1 is constructed by filling the space between the outer box 2 and the inner box 3 with a heat insulating material 4, with the duct auxiliary member 9 and the duct member 6 attached to the inner box 3.

After constructing this main body 1, the blower 11 is attached to the recess 6A through the notch hole 8 from the side of the freezer compartment 3a and using the recess 10.
A fan partition plate 21 forming a part 1' is attached to the inner box 3 facing the notch hole 8.

A partition wall front member 23 that forms a suction passage 24 for the refrigerator compartment is attached to the front end of the heat insulating partition wall 15, and a heat insulating material 27' for supporting the bottom plate of the freezer compartment is placed on the top surface of the cooler 25. A freezer compartment bottom plate 27 having a suction port 28 is inserted into grooves or rails formed on the left and right walls of the inner box 3 through the front opening of the main body 1 and placed at a predetermined position.

As a result, a cold air passage 7 is formed between the freezer compartment bottom wall 26 made of the freezer compartment bottom plate 27 and the heat insulating material 27' and the partition wall portion 3b, and the cooler 25 is housed therein. A freezer compartment 16 is formed by the and freezer compartment portion 3a, and a refrigerator compartment 17 is formed by the heat insulating partition wall 15 and the refrigerator compartment portion 3C.

When removing the blower 11, it is removed through the notch hole 8 with the freezer compartment bottom plate 26 removed and the fan partition plate 21 removed.

At the edge of the notch hole 8, the upper surface of the partition wall portion 3b, that is, the cooler 2
A waterproof wall 29 is formed in the duct auxiliary member 9 to protrude higher than any part of the dew receiving surface that receives the defrosting water in step 5, and the waterproof wall 29 is formed in the hole 8.
9 is fitted and positioned.

Therefore, the defrosting water does not flow into the recess 10 and is completely drained to the drain port 5, so that it does not freeze inside the recess.

As is clear from the above configuration, the present invention has a cold air passage passing through the notch hole 8 in the duct auxiliary member 9, and the air cooled by the cooler 25 is sent from the cold air passage 20 to the respective discharge ports. At 18.19, the air flows into the freezer compartment and the refrigerator compartment, and returns to the cold air passage 7 through the suction port 28 and suction passage 24.

Since the present invention is constructed as described above, the thickness of the partition wall that separates the freezer compartment and the refrigerator compartment is not increased, and the internal volume of the freezer compartment and the refrigerator compartment is not reduced. Since it can be formed into a thick part, the heat insulating part of the heat insulating box can be used effectively, and in this case, the structure that prevents the heat insulating material from leaking into the cold air passage becomes easy and the number of parts can be reduced.

In addition, the waterproof wall prevents defrosting water from entering the recess, so there is no risk of freezing near the intake port of the blower and reducing the amount of cool air circulating.There is also no reduction in the area of the recess due to freezing, so the blower There is no decrease in efficiency, and repair and replacement of the blower can be accomplished extremely smoothly.

In addition, by providing the waterproof wall on the duct auxiliary member, when installing the duct auxiliary member in the notch hole, the duct auxiliary member can be positioned by aligning the waterproof wall with the notch hole. This makes work etc. extremely easy.
