Abstract

PURPOSE:To prevent water droplets adhered to an outlet pipe of a cooling device from flowing into an inner box during defrosting operation and further to prevent rusts from occurring at an outer box or a thermal insulating effect from being damaged by a method wherein a midway part of an outlet pipe within the inner box is bent downwardly to form a bent part. CONSTITUTION:A midway part (a midway part reaching to a pipe outlet port 55 of an inner box) in an outlet pipe 51 within a cooling chamber 3 is formed with a bent part 56 bent downwardly. Since the bent part 56 bent downwardly in the cooling chamber 3 is formed, water droplets adhered to the surface of the outlet pipe 51 of the cooling device can be collected at a predetermined position in an inner box and dripped when the cooling device 34 is defrosted. Water droplets adhered to the outlet pipe 51 of the cooling device is positively prevented from being flowed out of the inner box 6 through the pipe outlet 55 and then occurrence of rust at the outer box 5 or a reduction in a thermal insulating effect can be prevented. In addition, since the water droplets are always dropped at the predetermined positions, then arrangement of the dew receiving pan 35 at the predetermined positions enables the water droplets to be eliminated.

On the other hand, a molded heat insulating material 32 and a partition plate 33 are provided behind the back plate 28.
As a result, a cooling chamber 3 is constructed, and a cooler 34 included in the refrigeration cycle is housed and installed within this cooling chamber 3. This cooler 34 is a so-called cross fin tube type heat exchanger in which a plurality of metal fins are attached to a refrigerant pipe.
It is provided vertically along the back surface of the inner box 6, and as shown in FIG.
It is installed with an inclination of 5° to 30" to the left. Due to this inclination, the defrosting water flows downward along the fins during defrosting, and drips from the lower end. I can do it.

Here, since the back plate 28 has a semicircular arc shape, an ineffective space is created at the corners of both sides of the cooling chamber 30, but this ineffective space is utilized to discharge cold air extending in the vertical direction by the molded heat insulating material 32. A duct 40 and a cold air return duct 41 are configured. This cold air discharge duct 40 communicates with the blower 37, and has cold air discharge ports 42 formed in the back plate 28 corresponding to the left corners of each space partitioned by the shelf 24.
It is open to the inside of the freezer compartment 2. Similarly, the cold air return duct 41 is opened into the freezer compartment 2 through cold air suction ports 43 formed at the right corner of the back plate 28 corresponding to each space, and is connected to the cooler 34. It communicates with the middle of the cold air suction side 3B.

The cold air completely cooled by the cooler 34 is sucked into the cold air discharge side 3A on the left side by the blower 37, and then is sent to the cold air discharge duct 40 in the front. The cold air that has flowed into the cold air discharge duct 40 is discharged into the space above each shelf 24 from each cold air discharge port 42 . At this time, the cold air is blown diagonally forward from the cold air outlet 42, flows through the space above the shelf 24 as shown by the arrow in FIG.
3... into the cold air return duct 41 and the cooler 34
It returns to the middle of the cold air suction side 3B. Furthermore, since the cooler 34 is tilted but laid flat, the cold air flowing in from the cold air suction port 43 flows from the cold air suction side 3B to the cold air discharge side 3A.
It is possible to realize a cold air circulation path with a simple configuration and low ventilation resistance.
