DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage such as a refrigerator or a freezer provided with an evaporating pipe in an inner box.

[0002]

2. Description of the Related Art A conventional refrigerator is disclosed in Japanese Patent Publication No. 5-221.
No. 48, there is no treatment of the defrosting water generated on the freezer compartment side surface of the inner box. Japanese Utility Model Publication No. 38-18487 discloses an electric refrigerator having a defrosting water channel formed on the back of an inner box. In this case, the inner box itself is provided with a drain recess formed at the bottom of the refrigerator main body. Water flows down through a water guide groove formed vertically along the inner wall of the refrigerator, and is guided to an evaporating dish equipped with an electric compressor to evaporate the water, which is treated as a cooler. Is not suitable, and the water guide groove of the defrost water is only on the back of the inner box, and the water guide groove of the defrost water is not provided on the side surface of the inner box.

[0003]

For this reason, in the conventional refrigerator, the frost generated on the freezer compartment side surface of the inner box becomes defrosting water by the defrosting operation and flows down when the door is opened. The present invention solves the above-described problem, which may leak out of the refrigerator from the front opening edge and wet the floor surface. The aim is to provide a storage to prevent.

[0004]

Means for Solving the Problems An inner box, an outer box filled with foam insulation between the inner box, an evaporating pipe provided on at least a side surface of the inner box, and a lower part of the inner box. The inner box is provided with a guide located forward of the evaporating pipe and guiding the defrosted water to the defrosted water receiver.

[0005]

According to the present invention, as described above,
During the defrosting, the defrost water does not climb over the guide portion but flows down along the guide portion and is received by the lower defrost water receiver, so that it does not leak out of the refrigerator. .

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

[0007] 1 is a freezer body, 2 is a door, 3 is a flat or container-shaped shelf that is removably inserted into and removed from the freezer compartment, and 4 is a container-shaped defrosting water that is disposed at the bottom of the freezer compartment. It is received. The door body 2 is provided with a door pocket 5.

The freezer main body 1 is formed of an outer box 6, an inner box 7, and a foam insulating material 8 such as polyurethane foam filled between the outer box and the inner box. An evaporation pipe 9 is attached to the inner box 7. A condensation pipe 10 is provided on the back of the outer box 6. The condensation pipe 10 has a dew-prevention pipe 10a disposed at the front opening edge of the freezer main body 1.
Is connected.

The inner box 7 is made of a synthetic resin such as ABS or styrene by vacuum forming, and is provided with a plurality of upper and lower pairs of shelf receiving ribs 11 protruding toward the freezer compartment on both left and right sides, and a foam insulating material side. A groove 12 for the evaporating pipe 9 to be provided, a guide rib 13 for defrosting water protruding toward the freezer compartment, and defrosting water located on both left and right side walls of the inner box 7 and forward of the front end of the evaporating pipe 9. Is formed integrally with the vertical groove-shaped guide portion 14 for guiding the water to the defrost water receiver 4 and the concave recess portion 15 on the bottom surface.

The guide portion 14 extends from above the uppermost arrangement groove 12 and below the lowermost arrangement groove 12. The upper end 14a of the guide portion 14 is formed from a portion above the upper end 14a by being formed in a portion where the side wall of the inner box cooled by the evaporating pipe 9 has little thermal influence and has a small cooling degree and is hardly frosted or dewed. The defrosting water or the water drops flowing in front of the part 14 is prevented from leaking out of the refrigerator. The lower end 14b has a small thermal effect similarly to the upper end 14a, and is formed close to the guide rib 13, so that the defrost water or the water droplet is surely guided to the defrost water receiver 4. When the defrosted water that has flowed down cannot be received by the defrosted water receiver 4, the defrosted water is received by the concave recess 15 so as not to leak out of the refrigerator.

[0011] The evaporating pipe 9 is, as shown in FIG.
In order to improve heat exchange, it is disposed in the disposing groove 12 and its back surface is covered with a heat conductive thin film 16 with an adhesive such as aluminum foil. The evaporating pipe 9
And the front end 16a of the thermal conductive thin film 16 is disposed at a position rearward of the guide portion 14.
It is designed to reduce the thermal effects on

The width dimensions (d1) and (d2) of the arrangement grooves 12 on the left, right, left and right sides of the arrangement grooves 12 formed in the inner box 7.
Are smaller than the width dimensions (D1) and (D2) of the left and right side surfaces and the back surface, thereby forming flat portions (W1) (W2) and (W3) and (W4) on the front and rear sides of the left and right surfaces and on the left and right sides of the back surface. The defrost water or the water droplets are made to flow easily, so that the defrost water can be reliably received by the lowermost defrost water receiver 4.

Further, since the guide portion 14 is formed as a concave groove protruding toward the foam insulating material 8 side, the foaming jig can be formed in a shape conforming to the shape of the inner box when the foam insulating material is filled. Although a gap is not generated between the inner box and the inner jig and the inner box is prevented from being deformed, it is preferable, but a protruding rail shape may be used. .

[0014]

According to the present invention, since the inner box is provided with the guide portion located forward of the evaporating pipe and leading to the defrosted water receiver,
At the time of defrosting, the defrost water does not climb over the guide portion but flows down along the guide portion and can be received at the lower defrost water receiver, so that it can be prevented from leaking out of the refrigerator.
