Reference numeral 1 denotes a main body having a heat insulating structure. An inner box 3 made of a hard synthetic resin, which is to be incorporated into the outer box 2 made of a steel plate with a space therebetween and is opened forward, and a foam insulating material 4 is filled between the outer box 2 and the inner box 3. 3, a freezer compartment 5 is formed.

[0003] The front opening of the freezer compartment 5 is closed by a drawer door 6 provided with a packing 7 on both sides so as to be openable and closable by a rail (not shown), and a freezer container 8 for storing and freezing frozen products in the freezer compartment 5 is mounted. Have been.

As shown in FIG. 5, the freezer container 8 is a rectangular box-shaped body having an open top, and a cutout step 8a for forming a cool air flow path at the upper end of the back wall and the cutout step 8a. A plurality of cold air outlets 8c1 are formed at the edges 8b on both sides and the upper end 8c of the front wall 8d, and are attached to the drawer door 6 by means not shown. In addition, the freezer 5
A cool air outlet 9 is formed at the rear, and a cooler 10 is provided behind the freezer compartment 5.

[0005] Here, the cool air cooled by the cooler 10 flows from the cool air outlet 9 of the freezer compartment 5 as shown by the arrow A, and the cool air passes through the inside of the freezer container 8 to cool the article to be frozen. The cool air flows out of the plurality of cool air outlets 8c1 at the upper end 8c of the front wall 8d of the freezer container 8, and returns to the cooler 10 from below through a cool air flow path formed between the front wall 8d and the drawer door 6. Circulated.

[0006]

The conventional FIG.
In the configuration of the freezer container 8 shown in FIG. 5, the plurality of cold air outlets 8 at the upper end 8c of the front wall 8d of the freezer container 8 are provided.
A part of the cool air flowing out from c1 may flow laterally from left and right from both sides as shown in B1 and B2 in the drawing, and the cool air may leak to the outside from the packing 7 between the drawer door 6 and the main body 1.

In view of the above, an object of the present invention is to provide a freezer container for a storage that restricts the flow of cold air in a freezing room and minimizes leakage of cold heat to the outside in order to solve such a problem. .

[0008]

According to the first aspect of the present invention, there is provided a main body having an open front surface, a door closing the opening of the main body, a freezing room formed inside the main body and the door, and the freezing room. Formed in a box-like body having an opening at the upper side, and a cool air introducing portion is formed at an upper end of a rear wall of the box-like body, and a cool air outlet is formed at an upper end of a front wall facing the rear wall. A storage that includes a freezer container, and that introduces cool air from a cool air introduction portion of the freezer container, draws the cool air from the cool air outlet, and forms a cool air circulation passage through a cool air passage formed between the front wall and the door. In this freezer container, cold air regulating members are provided at both ends of the front wall of the freezer container to guide cool air in the cool air flow path downward and to regulate cool air flowing in the left-right direction. According to this means, the cool air regulating member prevents the cool air from flowing downward and hitting the door packing from the left and right directions. Therefore, heat loss in packing the door is reduced, the cooling capacity can be improved, and the power consumption can be reduced.

According to a second aspect of the present invention, in the freezer container of the storage according to the first aspect, the cool air regulating member partitions the flow of the cool air in the left-right direction of the cool air flow path to prevent the cool air from hitting the door packing. A pair of regulating ribs erected in the directions are mounted corresponding to both ends of the front wall. According to this means, cold air is prevented from hitting the packing of the door by the regulating rib, and heat loss is reduced.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a refrigerator-freezer serving as a storage according to an embodiment of the present invention, wherein reference numeral 1 denotes a heat-insulating main body (hereinafter referred to as a main body). An inner box 3 made of a hard synthetic resin which is assembled into the outer box 2 with a space therebetween and is opened forward, and a foam insulation material 4 of a foaming method in place is filled between the outer box 2 and the inner box 3. It is configured.
The inner box 3 is vertically divided by an upper partition wall 11, a refrigerator compartment 12 is formed above the partition wall 11, and a two-stage freezer compartment 5 is formed below the lower partition wall 11. Wall 1
3 to form an upper and lower freezer compartment 5,
A vegetable compartment 14 is formed on the lower side.

A front opening of the freezer compartment 5 is closed by a drawer door 6 so as to be openable and closable by a rail (not shown). Each of the drawer doors 6 is provided with a freezer container 15 for storing a frozen product. On the back, a cooler 10
And a cool air fan 16 serving as a cool air circulation device
7.

A front opening of the refrigerator compartment 12 has a door 1 also serving as heat insulation.
8, a refrigerator 19 is provided in the refrigerator compartment 12 with shelves 19 for placing refrigerated goods in three stages vertically, and an ice warm room 21 below the shelf 20 is arranged below the refrigerator compartment 12. Door 18
