Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a refrigerator in which a storage unit for a large bottle or the like is provided on a bottle shelf of a storage room door.

2. Description of the Related Art In recent years, a refrigerator in which a bottle shelf is provided on a door of a storage room and a large-sized bottle storage portion is provided in a part of the bottle shelf has become mainstream.

Conventionally, this type of refrigerator has a general structure such as NR-C9Z1 sold by Matsushita Electric Industrial Co., Ltd. in March 1989. The configuration will be described below with reference to FIGS. 3 and 4.

As shown in the drawing, a cold air discharge port 2 of a cool air discharge air passage (not shown) is provided on the top surface of the storage chamber 1. Storage room door 9
Is composed of an outer frame 3, an inner plate 4, and a foaming heat insulating material 5.
A bottle shelf 6 is installed in the. A recess 7 is provided in the inner plate 4 to form a large-sized bottle storage unit 8. In the above configuration, the large bottle storage section 8 is located directly below the cold air discharge port 2.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional refrigerator, since the large bottle storage portion is located directly below the cool air discharge port 2, dew condensation occurs on the surface of the outer frame 3 of the storage chamber door 9 of the large bottle storage portion 8. A phenomenon has occurred. That is, in the large-sized bottle storage portion 8, since the recess 7 is provided in the refrigerator door inner plate 4 to secure the space for storing the large-sized bottle, the large-sized bottle storage portion 8 has a thin foam insulation material. Further, in the large-sized bottle storage section 8, since it is directly exposed to the cool air discharged from the cool air discharge port 2, it is the location in the refrigerator where the difference in temperature from the surroundings of the refrigerator is the largest. Therefore, in the large-sized bottle storage section 8, the cold air inside the refrigerator is transmitted to the outer frame of the refrigerator door and a dew condensation phenomenon occurs.

The present invention solves the above-mentioned problems, and an object of the present invention is to prevent the dew condensation phenomenon in the large bottle storage portion of the storage compartment door of the refrigerator.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is to arrange a large bottle storage portion of a storage compartment door of a refrigerator at a position avoiding a position directly below a cool air discharge port on the top surface of the storage compartment. .

Effect The present invention, due to the above-described configuration, prevents the large bottle storage portion from being directly exposed to the cold air, reduces the temperature difference from the surroundings of the refrigerator, and prevents the condensation phenomenon in the large bottle storage portion of the refrigerator storage door. Is something that can be done.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. As shown in the drawing, a cool air discharge port 2 of a cool air discharge passage (not shown) is provided on the top surface of the storage chamber 1. The storage chamber door 9 comprises an outer frame 3, an inner plate 4, and a foaming heat insulating material 5 filled in a gap between the outer frame and the inner plate, and a bottle shelf 6 is fixed to the inner plate 4 by fitting. A recess 7 is provided in a part of the inner plate 4, whereby the width of the bottle shelf is widened to form a large-sized bottle storage unit 8. The large bottle storage portion 8 is arranged at a position avoiding immediately below the cold air discharge port 2.

The operation in the above configuration will be described. The cool air discharged from the cool air discharge port 2 on the top surface of the storage chamber descends along the inner plate 4 of the storage chamber door and reaches the bottle shelf. At this point, the temperature difference between the cool air and the outside of the storage chamber is the largest, but the foaming heat insulating material 5 of the storage chamber door has a sufficient thickness, and the dew phenomenon does not occur on the door outer frame. This cold air draws heat from the food on the bottle shelf and raises the temperature. The cold air then circulates to the large bottle shelf. In the large-sized bottle storage portion 8, the thickness of the foaming heat insulating material 5 on the door of the storage room is thin, but the temperature difference between the outside of the storage room and the cool air is small, and the condensation phenomenon does not occur on the outer frame of the door. There is no.

As described above, according to the refrigerator of the embodiment of the present invention, since the large-sized bottle storage portion 8 is arranged at the position in front of the top surface of the storage room and below the cool air discharge port 2, dew condensation occurs on the outer frame of the door. There is no such thing.

Further, as described above, since the thickness of the foaming heat insulating material of the storage room door is arranged so as to correspond to the temperature of the cold air in the storage room, the thickness of the storage room door can be reduced.

Advantageous Effect of the Invention As is apparent from the above embodiments, according to the present invention, the large bottle storage portion of the storage chamber door is arranged at a position on the top surface of the storage chamber that is located directly below the cold air outlet, so that the door outer frame is provided. It is possible to prevent the dew condensation phenomenon. Since the thickness of the door of the storage chamber can be reduced, the foaming heat insulating material can be saved, and the volume of the storage chamber can be increased.
