Description

TECHNICAL FIELD The present invention relates to a refrigerator / freezer.

[Conventional technology]

FIG. 6 is a side sectional view showing a main part of a conventional refrigerator-freezer shown in, for example, Japanese Patent Application No. 1-138104, and FIG. 7 is a perspective view of the inside of a door.

In FIG. 6 of the drawings, 1 is a refrigerating / refrigerating body, 2 is a freezing compartment for forcibly circulating cold air for cooling (hereinafter referred to as a first freezing compartment), 3 is a door inner plate portion of the first freezing compartment 2. 15 is covered with a lid 16 that can be opened and closed, and a cool air intake 16 is placed on top of the lid 16.
The second freezer compartment 4 having b is a refrigerating compartment partitioned from the upper part by a heat insulating wall 5. In addition, a cooler chamber 6 is arranged in the rear part of the first freezing chamber 2, and a fan 7 is provided above the cooler 6a.
Is covered with a partition plate 8 and stored. A partition inner plate 9 is provided on the back surface of the partition plate 8, and a mouse case 10 is formed on the upper portion. A freezer compartment outlet 11 is provided on the upper part of the partition plate 8, and a freezer compartment inlet port is provided on the upper surface of the heat insulating partition wall 5.
12 and communicates with the lower part of the cooler 6a by a suction duct 13.

The second freezer compartment 3 is covered with a box-shaped opening / closing lid 16 (see FIG. 2) whose one side is pivotally supported on the inner plate 15 of the freezer compartment door 4 and a pocket 17 installed at the lower part of the door inner plate 15. Compartments are formed. Reference numeral 18 denotes a cold air duct, which is attached to the inner box 19 at the ceiling of the first freezer compartment 2, the front end 18a of the duct 18 is wrapped in the recess 16a of the lid 16, and the cold air outlet 18b is used as the cold air intake 16b. They are facing each other. Reference numeral 19a is a cool air discharge port provided at the bottom of the door pocket 16.

Next, the operation of the conventional example will be described with reference to FIGS. 6 and 7. The cool air cooled by the cooler 6a is blown out from the outlet 11 to the first freezer compartment 2 by the fan 7 to cool the first freezer compartment 2, and a part of the cool air is cooled by the cool air duct 18
Through the cold air outlet 18b to the cold air intake 16b of the second freezer compartment 3 of the opposite freezer compartment door 14 that cools the inside and is sucked into the suction duct 13 from the cool air outlet 19a, thereby cooling the cooler room. Return to 6. Since the opening / closing lid 16 has appropriate heat insulation and airtightness, the temperature of the second freezing compartment 3 is not affected by the room temperature of the surrounding first freezing compartment, and the temperature inside the first freezing compartment 2 is not affected. A certain amount of cold air is supplied from the cold air duct 18 without being affected by the change in the amount of cold air circulating in the first freezer compartment 2 depending on the amount of food.

[Problems to be Solved by the Invention]

As described above, in the conventional example, in order to send sufficient cool air to the freezer compartment door by the cool air duct, the cool air duct must be made large, which is why the cool air duct projects to the first freezer compartment side. In addition to the poor storage of food in the refrigerator, since there is only one cold air outlet to the second freezer, the temperature distribution inside the second freezer may be poor depending on the amount of food stored in the second freezer. However, there is a problem in that it may affect the freshness of the food.

The present invention has been made to solve the above-mentioned problems, and an auxiliary cold air duct for cooling the second freezing compartment makes the temperature distribution in the second freezing compartment uniform, thereby preserving food. It is an object of the present invention to provide a freezer-refrigerator that improves the storage quality of food by reducing the overhang of the duct toward the first freezer compartment.

[Means for Solving the Problems]

Therefore, the present invention is directed to a first freezing chamber for forcibly circulating the cool air from the cooler in the partitioned chamber, and the first freezing chamber.
A second freezing chamber that covers the inner plate portion of the door that opens and closes the freezing chamber with a lid that can be opened and closed, and has a plurality of cold air intake ports in a part of the lid, and a partition wall that partitions the first freezing chamber Has a plurality of cold air outlets that are arranged to face the plurality of cold air intakes of the second freezing chamber, and supply cool air from a cooler that cools the second freezing chamber. It is an object of the present invention to achieve the above-mentioned object by a freezer-refrigerator that is provided with a cool air duct that blows out and an auxiliary cool air duct that is formed in front of the cool air duct so as to blow cold air branched from the cool air duct.

Further, in the above invention, the cold air duct comprises a duct cover integrally formed with a cold air guiding rib provided on the heat insulating material side of the freezer-refrigerator body and a duct provided on the first freezer compartment side. Therefore, the above-mentioned object is to be achieved.

[Action]

The first freezer compartment of the refrigerator / freezer according to the present invention is cooled by forced circulation of cold air, and the second freezer compartment is covered with an automatic opening / closing lid on the inner plate of the door of the first freezer compartment. Take in cold air through the intake.

Further, the cold air duct arranged in the ceiling portion of the first freezing chamber sends and blows out the cool air for cooling the second freezing chamber, and the auxiliary cold air duct is provided with a plurality of cold air blowing ports branched from the cold air duct (18b, Cool air is blown from 25, 26) to blow into the plurality of cold air intake ports (16b, 21, 22) to uniformly cool the temperature distribution in the second freezing chamber.

Further, in the above invention, since the cold air duct is composed of the duct cover integrally formed with the cold air guiding rib provided on the heat insulating material side of the refrigerator-freezer body, and the duct provided on the first freezing compartment side, The overhang of the cold air duct can be reduced.
