Description

[Detailed Description of the Invention] The present invention relates to a forced draft cooling type refrigerator, and particularly to one in which a partition wall separating a refrigerator compartment and a freezing compartment is formed integrally with an inner box.

Conventionally, in this type of product, a cooling passage or a cooler is placed in a partition wall that is paired with the inner box, or a separate cross rail is provided at the tip of the partition wall, and the gap between the two is used as an air path. There are things like that.

In the former case, the passage structure is complicated and it is difficult to seal the foamed heat insulating material, and in the latter case, sealing the gap between the partition wall and the cross rail becomes troublesome.

In view of these points, the present invention aims to provide a refrigerator that has a simple configuration and is easy to manufacture.

An embodiment of the present invention will be described in detail below.

Reference numeral 1 denotes a refrigerator main body, the interior of which is divided into a freezing compartment 3 and a refrigerating compartment 4 by a partition wall 2' formed integrally with an inner box 2.

A cooling room 5 is provided at the rear of the freezer compartment 3 and divided by a partition plate 5a, and houses a cooler 6 and a fan 7 placed on the windward side.

Reference numeral 8 designates a freezer compartment side suction hole provided in the partition plate 5a, 8a designates a freezer compartment side discharge hole, and 9 designates a discharge duct that blows air into the refrigerator compartment 4.

Reference numeral 10 denotes a refrigerating compartment side suction duct provided within the partition wall 2', and is composed of a molded heat insulating material 11 made of foamed polystyrene or the like and a mounting plate 12 molded of plastic or the like.

A recessed groove 13 is formed in the molded heat insulating material 11, and a refrigerating compartment side suction hole 14 is provided on the front surface of the recessed groove 13.

By attaching the molded heat insulating material 11 to the concave portion 16 of the top surface 15 of the refrigerator compartment box of the partition wall 2', a refrigerator compartment side suction duct 10 is formed between the groove 13 of the molded heat insulating material 11 and the inner box 2. ing.

Further, 17 is a through hole passing through the partition wall 2', one end of which opens at the rear end of the groove 13, and the other end of which opens below the cooling chamber 5.
In particular, it opens in an inclined part 2c between a raised part 2a and an exposed recessed part 2b formed integrally with the partition wall 2'.

Further, 18 is a heat insulating material provided between the partition plate 5a and the cooler 6,
A backflow prevention piece 18a is provided which extends above the through hole 17 and prevents cold air from the cooling chamber 5 from flowing into the refrigerator compartment 4 through the through hole 15 due to its own weight when the fan 7 is stopped.

19 is a cross rail decorative board, and 20 is a cross rail mounting sash, which also supports the front end of the mounting plate 12 with a lower end locking piece 20a.

Next, the functions and effects of the above configuration will be explained.

During cooling operation, cold air circulates within the refrigerator as shown by the arrow in FIG.

A part of the cold air discharged from the fan 7 is transferred to the freezer compartment side discharge hole 8
The cold air enters the freezer compartment 3 from a, returns through the freezer compartment side suction hole 8, and the remaining cold air passes through the discharge duct 9 and is discharged into the refrigerator compartment 4 from the discharge hole 21.
4 and circulates to the groove 13, the through hole 17, and the cooler 6.

At this time, by installing the suction duct 10 having the suction hole 14 on the top surface of the refrigerator compartment, the suction hole 14 can be installed at a position relatively distant from the discharge hole 21, and the temperature distribution in the refrigerator compartment can be optimized without causing a short circuit. ing.

Further, since the suction duct 10 is installed in the recessed part 16 of the inner box, it does not protrude below the partition wall 2', and a food storage space is secured.

As described above, the present invention forms a concave part on the top surface of the refrigerator compartment box, arranges a grooved molded heat insulating material in this concave part, and creates a refrigerator compartment side intake duct between the inner box and the molded heat insulating material. Because of this, the suction hole can be installed at a position relatively distant from the discharge hole, and the temperature distribution within the refrigerator compartment can be optimized without short circuiting.

In addition, the suction duct can secure food storage space without protruding below the partition wall.Furthermore, only the through hole on the suction side penetrates the partition wall, which is integrated with the inner box as an air path, and its seal Since the work is simple and the dimensions are short, it is easier to assemble and can be manufactured at a lower cost than conventional methods.
