Abstract

PURPOSE:To form an air return passage, secure a necessary inlet port, lessen the resistance of an air passage, and obtain a sufficient cooling performance by providing openings on the side walls of partition plates dividing the interior of a freezing chamber, and further by disposing an inlet port at a position where the partition plates abut against a duct cover. CONSTITUTION:The side walls of partition plates 13a and 13b for dividing the interior of a freezing chamber 2 into two parts and forming the right and left chambers are provided with openings 16a and 16b, respectively, and a lower part where the partition plates 13a and 13b abut against a duct cover 7 is further provided with an inlet port 17. The openings 16a, 16b and the inlet port 17 form an air passage communicating to one another. Since it is so designed that an air return passage is formed between the partition plates 13a and 13b, the resistance of the inlet air passage is lessened to a great extent.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a forced cold air circulation type refrigerator-freezer.

Conventional technology is configured. Reference numeral 6 denotes a cooler, which is installed on the back side of the freezer compartment 2 and includes a blower 6 that forcibly circulates cold air to the freezer compartment 2 and the refrigerator compartment 3. 7 is a duct cover connected to a duct 8 that divides cold air into the freezer compartment 2 and the refrigerator compartment 3;
The duct 8 is connected to a temperature control device 9 of the refrigerator compartment 3.

The temperature control device 9 includes a damper opening/closing device that adjusts the amount of cold air discharged to the refrigerator compartment 3 and a cold air discharge passage (
(not shown), and a dial /l/ that adjusts the opening degree of the damper opening/closing device 10 to change the set temperature of the refrigerator compartment 3.
It has 11. The inside of the freezer compartment 2 is further divided into two compartments by a trim 12 and partition plates 1aa and 13b.
The cold air discharge port 14 and the cold air suction port 16 of the duct cover 7 are used to extract and cool the freezer compartment 2 by the cold air circulated by the blower 6.

Problems to be Solved by the Invention However, in such a configuration, due to the provision of partition plates that further partition the inside of the freezer compartment 2, the number of cold air suction ports 16 in the duct cover 7 is reduced, increasing air path resistance and reducing cooling performance. It had the disadvantage of causing deterioration.

In view of the above problems, the present invention does not require a complicated air path configuration, and
By making slight improvements to the partition plates, air path resistance can be reduced and sufficient cooling performance can be obtained.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a plurality of openings in the side wall of the partition plate, and provides a suction port where the partition plate and the duct cover come into contact with each other. , the duct cover communicates with each other to form a return air path.

Effects According to the present invention, with the above-described configuration, a return air path is formed, a necessary suction port is secured, air path resistance is reduced, and sufficient cooling performance is ensured.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to FIGS. 1 and 2. Components that are the same as those in the prior art are designated by the same reference numerals, detailed explanations thereof will be omitted, and only different portions will be explained.

13a and 13b are partition plates for partitioning the inside of the freezer compartment 2 into two left and right compartments. Also, partition plates 13a and 13b
Openings 16a and 16b are provided in the side wall of the duct cover 7, and a suction port 17 is provided in the lower part of the duct cover 7 where the partition plates 13a and 13b come into contact with each other. The suction port 17 has a communicating wind path structure.

In this configuration, the cooler 5 cools the air blower 6.
The cold air is discharged into the freezer compartment through the cold air discharge port 14 of the duct cover 7. Further, the return air path to the cooler 6 is returned to the cold air inlet 16 and the openings 18a and 16b provided in the side walls of the partition plates 13a and 13b. It forms an air path that enters the abutting lower suction port 17 and returns to the cooler 6.

As described above, according to this embodiment, the partition plates 13a and 13
Since the return air path is formed inside b, the resistance of the suction air path is significantly reduced.

Effects of the Invention As described above, according to the present invention, an opening is provided in the side wall of a partition plate that partitions the inside of the freezing chamber, and a suction port is further provided at a position where the partition plate contacts the duct cover. By doing so, the following effects can be obtained.

(1) Suction air path resistance is significantly reduced and cooling performance is improved.

@) Instead of installing a dedicated part, it can be easily adopted by simply providing an opening in a conventional part and converting the conventional ineffective space into an air passage configuration.

(3) Since the suction port is disposed on the side wall of the partition plate, the temperature distribution inside the freezer compartment 2 is significantly improved compared to the conventional method.
