Abstract

PROBLEM TO BE SOLVED: To enhance an energy saving effect by a method wherein an opening part is provided at a lower part of a wall facing a door to discharge chilled air in a container outside and an auxiliary duct having a horizontal part almost parallel with a bottom part of the container is mounted on the internal surface of the door. SOLUTION: An opening part 62 is provided at a bottom part 61 on the side of a wall 38 facing a door 31 of a container 34 to discharge the chilled air in the container 34 outside while an auxiliary duct 63 which has a horizontal part 67 extending by a specified length L almost parallel with the bottom part 61 at a lower part of the opening part 62 is mounted on the internal surface of the door 31. The chilled air in the container 34 flows downward along the internal surface of the wall 38 but none between the door 31 and the container 34. The chilled air running downward along the internal surface of the wall 38 flows out hitting the horizontal part 67 of an auxiliary duct 63 and moves in the direction opposite to the door 31 but does not hat the tip part of a receiving part 13 heated to be kept from moving near the opening part of the door thereby achieving a higher energy saving effect.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a high energy saving effect.

[0002]

2. Description of the Related Art In a conventional refrigerator 1, for example, as shown in FIG. 11, a plurality of refrigeration compartments 2, a freezing compartment 3, and a vegetable compartment 4 are provided in this order from the top, and a refrigeration compartment is provided in front of each compartment. 2 is a door 21 (swing-out type door), and a freezer compartment 3 is a door 31
(Drawer-type door), door 32 (drawer-type door), and vegetable room 4 are provided with door 41 (drawer-type door). The freezer compartment 3 is provided with containers 34 and 35, in which ice made frozen food or frozen food is put in the container 34, and frozen food or the like is put in the container 35. Vegetable room 4 also has container 43
Is provided.

[0003] Door packings 22, 39, 33, and 42 are respectively provided over the entire periphery at the end of the inner surface of each door.
Receiving part 11 (the upper end of the box of refrigerator 1) forming the receiving surface of each door packing, receiving part 12 (the end of the partition separating compartments 2 and 3), and receiving part 13 (door 31) And the receiving part of the door 32), the receiving part 14 (the end of the partition separating the freezer compartment 3 and the vegetable compartment 4), the receiving part 15 (the bottom end of the box of the refrigerator 1), etc. Thus, the cool air is prevented from leaking to the outside, and the cool air is circulated in the order of, for example, the freezing room 3, the refrigerating room 2, the vegetable room 4, etc., so that each room is maintained at an optimum temperature. 51 is a compressor for compressing the refrigerant, 52 is an evaporator for evaporating the refrigerant and exchanging heat with the air in the refrigerator to cool it, and 53 is a fan for circulating cool air.

FIG. 12 shows a refrigeration cycle of the refrigerator 1. The refrigerant compressed by the compressor 51 first flows to the dip condenser 54 used for evaporating the drain water, then flows to the main condenser 55 and then flows upward, as shown by the arrow, as shown by the arrow. After passing through a crest condenser 56 for preventing sticking, it flows through a conduit 60 provided in the receiving portions 11 to 16 and the like, and then flows into a capillary tube 57.
After being evaporated and cooled in the evaporator 52 through the
1 is compressed. The conduit 60 buried in the frontage of the main body is kept at about 5 to 7 ° C.
The heat is dissipated to a high degree to prevent the occurrence of dew condensation on the surfaces of the distal ends of the receiving portions 11 to 16.

There is a problem that the cold air is heated because the air flows through the gap between the bottoms, and the energy efficiency is reduced. The container 35 also has the cool air in the container 3.
Since the air flows through the cold air holes 37 as in the case of No. 4, there is a problem that the cold air is heated and the energy efficiency is reduced. SUMMARY OF THE INVENTION An object of the present invention is to provide a refrigerator having an improved energy saving effect by preventing cold air from flowing between a door and a container and substantially preventing cold air in the container from hitting a heated receiving portion. That is.

[0006]

Since the present invention is not limited to the above embodiment, various modifications can be made without departing from the spirit of the appended claims.

[0023]

According to the refrigerator of the present invention, an opening is provided at the lower part of the wall facing the door and / or at the bottom on the side of the wall to allow the cool air in the container to go out of the container, and the opening is formed on the inner surface of the door. Mounting an auxiliary duct having a horizontal section extending a predetermined length substantially parallel to the bottom of the container below the section,
Alternatively, such an auxiliary duct is provided integrally with the inner surface of the door, and the cool air flowing out of the opening is guided by the auxiliary duct so as not to go near the door opening. Can be efficiently cooled and a high energy saving effect can be achieved. It is easy to form the auxiliary duct integrally with the inner surface of the door made of a synthetic resin or the like, and it is possible to save labor for mounting the auxiliary duct. Since the bottom of the container is formed flat, for example, even if the container is taken out for cleaning or the like and placed on a flat surface, the container has good stability and is easy to handle. Further, since the volume of the container can be made larger than before, the effective internal volume can be made larger.

When the auxiliary duct is mounted between the mounting plate for fixing the rail supporting the container to the inner surface of the door and the inner surface of the door, the auxiliary duct is mounted on the door. It can be easily and firmly attached to the inner surface of the.

If the rail and the auxiliary duct are integrally formed of synthetic resin, the cost and weight can be reduced.

By providing an upward weir at the periphery of the opening and / or at the end of the auxiliary duct, it is possible to prevent liquid such as water collected at the bottom of the container from flowing downward.
