Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator / freezer, and more particularly to a cooling structure for a freezer compartment.

[0002]

2. Description of the Related Art FIGS. 6 to 8 are views showing a conventional cold air forced circulation type refrigerator / freezer. 6 is a vertical cross-sectional view taken along a plane orthogonal to the door, and FIG. 7 is a partially enlarged view of a range surrounded by a one-dot chain line Z in FIG. FIG. 8 is a perspective view showing the freezing case when the freezing case is partitioned at the center.

In each drawing, 1 is a refrigerator / freezer main body, 2 is a door that opens and closes the front opening of a storage chamber B, 3 is a cooler provided in a cooler chamber A, and 4 is a cooling chamber A and a freezer. The fan grill 5 that divides the room B and 5 is the fan grill 4
A bell mouth that forms an air passage by combining with a fan, 6 is a fan for circulating cold air, 7 is a refrigerating case for storing frozen products, 8 is an outlet for blowing cold air,
Reference numeral 9 is a suction port for returning cold air, which has cooled the frozen material in the case, to the cooler.
A for separating the vegetable compartment D from the vegetable compartment D is a divider B for partitioning the upper and lower freezer compartments, 12 is a magnet gasket for sealing between the main body opening and the door, and 13 is a steel plate for adsorbing the magnet gasket. Made of a front cover, 14 is a suction air passage for guiding the cool air that has cooled the freezer compartment case to the suction port, and 15 is a door inner plate. Further, as shown in FIG. 8, the freezing case 7a is divided into a frozen food storage chamber 7b for storing frozen foods and an ice making chamber 7c for storing ice-made ices according to the configuration.
In some cases.

Next, the operation will be described. The cool air that has passed through the cooler 3 by the fan 6 flows through the air passage between the fan grill 4 and the bell mouth 5 to the freezing case 7 from the outlet 8. Cold air that has cooled the food in the freezing case 7 returns to the cooler 3 from the suction port 9 through the suction air passage 14. On the other hand, the cold air blown out from the lower outlet 8 cools the food in the lower freezing case 7, passes through the floor surface of the freezing compartment B from the suction air passage 14 and is sucked from the inlet 9 to return to the cooler 3. The door inner plate 15 is not provided with a throat for the purpose of not blocking the suction air passage 14. Here, the throat refers to a gap between the protrusion of the inner plate of the door and the storage wall. Further, in the case of the freezing case 7a, cold air flows out from the blowout port 8 into both the frozen food storage chamber 7b and the ice making chamber 7c of the freezing case 7a to cool the food and ice in the freezing case 7a.

[0005]

Since the conventional cold air forced circulation type refrigerator / refrigerator is constructed as described above, the cold air that has cooled the inside of the freezing case 7 by the forced convection by the fan 6 passes through the suction air passage 14. At this time, by cooling the magnet gasket 12 in the vicinity, heat of the front cover 13 that comes into contact with the magnet gasket 12 is taken away, and there is a problem that dew condensation occurs on the front cover 13 when the outside air is humid. Further, there is a problem that the cold air blown into the freezing case 7 does not efficiently flow into the freezing case 7 and a short cycle occurs. The short cycle referred to here is that the cool air is sucked into the suction port before the inside of the case is sufficiently cooled. or,
In the case of the frozen case 7a, since the ice making chamber 7b and the frozen food storage chamber 7c exist in the same atmosphere, when a food with a strong odor is put into the frozen food storage chamber 7c, the odorous molecules of the food are adsorbed on the ice. There was a problem of degrading the quality of ice.

The present invention has been made to solve the above problems, and an object thereof is to prevent dew condensation on the front cover 13 and to efficiently cool the inside of the refrigerating case 7 by eliminating a short cycle. . It also prevents the smell of ice from the ice making room.

[0007]

A cool air outlet is provided on a wall surface of a freezing compartment, and a freezing case is provided in front of the outlet so that the cold air blown out from the cold air outlet flows into the freezing case and the freezing case. In a cold-air forced circulation refrigerator / freezer that flows out from a suction air passage provided at a position different from the upper side of the cold air inflow, an opening for taking in / out stored items above the freezing case and a lid covering the suction air passage are provided. Further, when the freezing case is divided into an ice making room and a frozen food storage room, an opening above the frozen food storage room side for taking in and out stored items and a lid for covering the suction air passage are provided.

[0008]

When the cold air that has cooled the freezing case is sucked in and passes through the air passage, the lid blocks the discharge of the cool air. Further, the lid prevents the cool air in the freezing case from flowing out from a place other than the suction air passage. Further, the ice making room and the frozen food storage room are cut off from each other.

[0009]

The present invention will be described in detail below with reference to examples. 1 is a vertical cross-sectional view of a refrigerator-freezer which is an embodiment of the present invention, FIG. 2 is a vertical cross-sectional view taken along line XY of FIG. 1, and FIG. 3 is a partially enlarged view of a range indicated by Z in FIG. 4 is a perspective view of the lid, and FIG. 5 is a perspective view of a freezing case showing another embodiment in the case of the freezing case 7a. 1 to 15, 18, 19 in the figure
Since this is a portion corresponding to the same reference numeral portion in the conventional example described in FIGS. 6 and 7, description thereof will be omitted here. Reference numeral 16 is a lid, and 17 is an opening formed in the rear portion of the lid.

Next, the operation of this embodiment will be described. The lid 16 runs horizontally to the left and right of the freezing case 2
It is fitted between the ribs 7d of the book and is slidable in the front-rear direction on the upper side of the freezing case 7. The freezing case 7
It is mounted in a frame composed of left and right frames (not shown) and a rear frame attached to the back surface of the door 2. Therefore, when the door 2 of the freezing compartment B is pulled out, the freezing case 7 and the lid 16 are pulled out. Since the lid 16 that has been pulled out can slide in the front-rear direction on the upper side of the freezing case, by pushing the lid 16 back into the freezing compartment B again, the upper opening of the freezing case 7 is opened and food in the freezing case 7 can be taken in and out. .
When the door 2 is closed, the freezing case 7 is pushed back into the freezing compartment B by the inner plate 15 attached to the freezing case 7, and the lid 16 covers the upper opening of the freezing case 7. At that time, the blow-out opening 8 of the fan grill 4 and the front opening 17 of the lid 16 are fitted together. The cool air that has passed through the cooler 3 by the fan 6 flows through the air passage between the fan grill 4 and the bell mouth 5 to the freezing case 7 from the outlet 8.
At this time, all the cool air flows out into the space formed by the freezing case 7 and the lid 16 because the front opening 17 and the front opening 17 of the lid 16 are fitted together. Therefore, short cycle can be prevented and efficient cooling can be performed. The cold air that has cooled the food in the freezing case 7 passes through the suction air passage 14, and at this time, the suction air passage 14 and the magnet gasket 1
Since the space between 2 is blocked by the lid 16, the cool air passing through the suction air passage 14 does not cool the magnet gasket 12. The cold air that has passed through the suction air passage 14 is sucked through the suction port 9 and returns to the cooler 3. On the other hand, the cold air blown out from the lower outlet 8 is in the lower freezing case 7.
The food inside is cooled, and is sucked from the suction air passage 14 through the floor surface of the freezing compartment B from the suction port 9 and returned to the cooler 3. In the case of the frozen case 7a as shown in FIG. 5, the lid 16 is provided at the upper opening of the frozen food storage chamber 7b. At this time, the lid 16 operates in the same manner as the combination of the freezing case 7 and the lid 16 described above. The front opening 17 and the front opening 17 of the lid 16 are fitted together,
The cold air flows out into the frozen food storage room 7b and sucks in the air passage 14
Pass through. The cold air that has cooled the frozen food storage chamber 7b is the lid 1
It is blocked by 6 and never flows into the ice making room.

[0011]

As described above, according to the present invention, a lid which covers the upper opening of the refrigerating case and the suction air passage is provided, and when cold air passes through the suction air passage, the magnet gasket is located in the vicinity. Since it does not cool the front cover, the heat of the front cover that comes in contact with the magnet gasket is not taken away, and even if the outside air is humid, it is possible to prevent the temperature of the front cover from falling below the dew point to prevent dew condensation on the front cover. It can be prevented. In the case of the frozen case 7a, the cold air that has cooled the frozen food storage chamber 7b is covered by the lid 16
In addition to the above effect, the frozen food storage chamber 7b is added to the ice making chamber 7c because it does not flow out from a place other than the suction air passage 14.
It is possible to prevent the smell of food from being absorbed.
