Description

[Detailed description of the invention] The present invention provides a refrigerator having an inner box integrally formed with an upper chamber portion, a lower chamber portion, and a partition wall portion that partitions these compartment portions into upper and lower compartments. It is an object of the present invention to provide a refrigerator that can reliably operate the cooling air and smoothly flow the cold air that has passed through the cooler.

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

Reference numeral 1 denotes an inner box that constitutes the refrigerator body A, which includes an upper chamber portion 1A forming the inner wall of the freezing compartment 13, a lower chamber portion IB forming the inner wall of the refrigerator compartment 14, and a partition wall portion 1C dividing these compartments 13 and 14 into upper and lower parts. It is formed integrally with a synthetic resin plate by vacuum forming or the like.

This partition wall portion has a shape in which grooves 15 that are open on the left, right and rear sides are formed on the back surface, and the grooves 15 are filled with a heat insulating material to form a heat insulating partition wall 19.

A cold air passage 16 with a predetermined interval between the upper surface of the partition wall portion 1C
A partition wall plate 12 is provided which is assembled to the inner box 1 to form a partition wall plate 12.

This plate 12 is connected to the bottom plate 12A of the freezer compartment 13 and the partition wall portion 1.
Mainly, the plate-shaped heat insulating material 11 has a planar area sufficient to cover the entire upper surface of the cooler 5 and the bottom plate 12A of the freezer compartment so as to sufficiently close the space between the cooler 5 placed on the cooler 5 It is configured.

Therefore, the cold air passage 16 is essentially created between the heat insulating material 11 and the partition wall portion 1C.

Reference numeral 17 denotes a partition front member which is located in front of the partition wall portion 1C and spans the entire width, and together with the partition wall portion 1C and the partition wall plate 12, constitutes a partition wall inside the refrigerator.

The upper surface of the partition wall portion 1C serves as a mounting surface for the cooler 5, so a drain port 2 is bored and a drain pipe (not shown) is connected to the partition wall portion 1C.
The water is disposed inside the main body A and drains to the outside of the main body A.

The cooler 5 is a plate-fin tube type in which a large number of plate-like fins 5C are arranged in parallel, and a refrigerant tube 5D is arranged in a meandering manner through the fins. Relatively thick side plates 5A and 5B are provided.

At the rear corners of the upper surface of the partition wall portion, there are rear end flanges 5 bent outward of the left and right rear portions of the side plates 5A and 5B of the cooler 5.
The protrusions 3, 3 that a, 5b come into contact with are formed integrally with the inner box 1.

On the back side of the inner box 1 above one of the protrusions 3, a bare cold pipe 6 leading to the cooler 5, that is, a capillary tube through which the refrigerant flows in and a suction pipe through which the refrigerant flows out, are covered with a heat insulating material 4 and pass through the main body A. A hole 7 extending outward is formed.

A cylinder 18 forming a hole 7A penetrating the main body A corresponding to the hole 7 is attached through the back wall of the main body 1 to form a guide hole for the extending portion of the refrigerant pipe 6.

A sealing putty 8 seals the gap between the holes 7 and 7A and the outer periphery of the refrigerant pipe 6.

Reference numeral 9 denotes a support part formed integrally with the heat insulating material 11, which is formed at the rear of the heat insulating material 11 made of styrofoam, etc., and supports the refrigerant pipe 6.
It has a height that covers the bottom plate 12A and supports the rear part of the bottom plate 12A, and abuts on the upper surface of the protrusion 3.

The part that covers the refrigerant pipe 6 is a groove 9' that opens downward, and one side is formed with an inclined surface 9A similar to the inclined surface 3A formed on the right protrusion 3, and this inclined surface 3A, 9A both act as guide surfaces so that the cool air that has passed through the cooler 5 is smoothly sucked into the blower 18.

The putty 8 is filled in the groove 9' so as to sufficiently seal the gap between the periphery of the refrigerant pipe 6 and the support portion 9.

As described above, the support part that covers the refrigerant pipe and supports the rear part of the bottom plate of the upper chamber is integrally formed with the heat insulating material on the cooler, so that the support part has a structure with a reduced number of parts. The position of the refrigerant pipe can be accurately aligned with the protruding part, the rear support of the bottom plate is sufficient, and the bottom plate does not sink downward even when heavy objects are placed, and the extending portion of the refrigerant pipe is sealed with putty. The protrusion allows for accurate positioning of the cooler relative to the blower and other parts, ensuring that the cool air flowing through the cooler is directed in the correct direction, thereby increasing the cooling effect. It can be maintained well.

In addition, the presence of the protrusion prevents the formation of a vortex of cold air at the upper corner of the partition wall portion, and the side surface of the protrusion can be used as a guide surface for the cold air, allowing the cool air to flow smoothly, resulting in high efficiency. Cold air circulation can be achieved.

Further, by providing the protruding portions at the upper corners of the partition wall portions, it is possible to reinforce the corner portions where the inner box is most likely to become thin when molded.
