BACKGROUND OF THE INVENTION
The present invention relates to a refrigerator provided with a condensation prevention heater in a partition.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a refrigerator in which a plurality of containers are arranged in the vertical direction with respect to a room such as a freezer room or a refrigerator room, and a plurality of pull-out doors for pulling out the containers are provided in the vertical direction. For example, in the conventional refrigerator shown in FIGS. 10 and 11, the refrigerator main body 1 opening forward is a steel plate outer box 2 that forms the outer shell of the refrigerator, a synthetic resin inner box 3 that forms the inner wall of the refrigerator, and an outer box. 2 and the inner box 3 are composed of a heat insulating material 4 filled and foamed, and divided into four chambers in the vertical direction by partition walls 13 and 14 and an intermediate partition 5 attached after filling and foaming.
[0003]
The middle partition 5 is composed of a middle partition upper plate 6, a middle partition lower plate 7, and a middle partition heat insulating material 8 positioned between the middle partition upper plate 6 and the lower plate 7. A decorative cover 9 formed in a U-shape is attached, a dew condensation prevention heater 10 is attached to the back surface of the decorative cover 9, and a front heat insulating material 11 is disposed on the back surface.
[0004]
FIG. 12 is an external view of a conventional condensation prevention heater. The condensation prevention heater 10 is placed on the aluminum foil 12 in a certain pattern, and an end portion is connected to a lead wire 10a to form a connection portion 10b.
[0005]
Next, the operation will be described.
In the above configuration, when electric power is supplied to the dew condensation prevention heater 10, the dew condensation prevention heater 10 is sandwiched between the front heat insulating material 11 at the front end of the partition and the decorative cover 9. Is heated by the dew condensation prevention heater 10 to prevent dew condensation.
[0006]
[Problems to be solved by the invention]
