A cooling air blowing outlet is disposed in a manner of blowing cooling air into a storage container, and a cooling air blowing inlet is disposed above the lowest portion of the cooling air blowing outlet. Air blown out from the cooling air blowing outlet is blown into the cooling air blowing inlet above the cooling air blowing outlet and turns back to a cooling air generating portion after the storage container is cooled. Thus, the air blown out from the cooling air blowing outlet does not flow downward between the storage container and a storage room, so that the exterior air does not enter the refrigerator from the connecting portion.

Description

refrigerator

The present application is based on and claims the benefit of Japanese Patent Application No. 2013-136406, filed on Jun.

An embodiment of the invention is directed to a refrigerator.

In the refrigerator, a heat insulating cabinet is formed by the heat insulating wall body, and a storage chamber is formed inside the heat insulating cabinet. There is also a refrigerator in which the storage container is placed in a form in which the bottom is close to the bottom of the storage compartment.

The heat insulating wall body constituting the heat insulating cabinet body generally has a structure in which a heat insulating material is disposed between the outer plate portion and the inner plate portion, but it is difficult to manufacture the heat insulating cabinet body by one heat insulating wall body. Therefore, the heat insulating cabinet body is configured by dividing the outer panel or the inner panel or the heat insulating material of the heat insulating wall body and appropriately connecting them. In this case, the structure in which the joint portion is located at the lower portion of the heat insulating cabinet may be employed. A heat insulating material such as a sponge is buried inside the connecting portion, but it is difficult to maintain the airtightness completely, and a slight gap may occur.

On the other hand, in the refrigerator, a cold air blowing port for generating cold air generating portion of the cold air is provided above the storage container, and a cool air return for cooling the storage room is provided in the interior of the storage room. Air intake. In this case, the cold air blown out from the cold air outlet exits the storage container, flows out of the storage container, and flows downward on the outside of the storage container, through the gap between the outer bottom surface of the storage container and the bottom surface of the storage chamber. The cold air suction port in the inner portion of the storage compartment returns to the cold air generating portion.

However, when the cold air flows into the cold air suction port through the narrow gap between the outer bottom surface of the container and the bottom surface of the storage chamber as described above, the flow velocity is relatively fast, and therefore, the inside of the refrigerator of the joint portion is opposed to the inside due to the flow of the cold air. The outside of the refrigerator is relatively negative pressure, and a small amount of outside air is sucked from the connecting portion of the lower portion of the heat insulating cabinet, and the outside air intrudes into the storage room or the heat insulating cabinet, so that it may be generated in the refrigerator or in the joint portion. Condensation.

In view of the above, the present invention provides a refrigerator capable of suppressing entry of outside air from the connecting portion in a refrigerator in which a connecting portion of a heat insulating wall body is present in a lower portion of the heat insulating cabinet.

The refrigerator according to the embodiment of the present invention includes: a heat insulating cabinet body having a box shape by a plurality of heat insulating wall bodies, a connecting portion in the heat insulating wall body at a lower portion, and a storage chamber formed therein; a storage container; Provided in the storage chamber at a bottom close to the bottom of the storage chamber, and having an upper surface open; and a cold air generating portion having evaporation And generating a cold air, blowing the cold air from the cold air outlet, sucking the cold air from the cold air suction port, and setting the cold air blowing outlet by blowing the cold air into the storage container And the cold air suction port is disposed above the lowermost end portion of the cold air blowing outlet.

The outlet 39 and the small freezer compartment are cooled by a cold air outlet 40. The lower refrigerating container cold air blowing port 37 is formed to face the upper portion of the lower freezing container 19 so as to be lower than the inside of the lower freezing container 19 so as to blow the cold air into the lower freezing container 19 (in this case, the lower portion) Part of the 19s upper). Further, the upper refrigerating container uses a cold air blowing port 38 to blow the cold air into the upper freezing container 20. The method is formed in a portion that becomes the upper portion of the upper freezing container 20 facing forward. In addition, the cold air blowing port 39 is formed in a portion facing the ice making chamber 5 so as to face the front side so that the cold air is blown into the ice making chamber 5. In addition, the cold air outlet 40 is formed in a portion facing the small freezer compartment 6 so as to face the front side of the small freezer compartment container 18 so as to blow cold air into the small freezer compartment.

The lowermost end portion of the cold air blowing port 37 for the lower freezing container is located above. In other words, the cold air suction ports 41a and 42a are located above the lowermost end portion of the cold air blowing port 37 that blows the cold air toward the lowermost freezing container 19, which is the lowermost storage container. Further, the cold air suction ports 41a and 42a are located on the front side from the cold air blowing ports 37, 38, 39, and 40.

The inner peripheral portion of the main freezing compartment 7 corresponding to the entire circumference of the fin 19a of the lower freezing container 19 (including the back side of the door 17 or the outer front surface of the casing 31, etc.) is provided with the fin 19a The shield portion 43 that is in contact with and is elastically deformable forms a blocking portion 44 from the shielding portion 43 and the fin portion 19a, and the blocking portion 44 blocks cold air from the opening of the upper portion of the upper freezing container 20 toward the main freezing chamber outside the upper freezing container 20. The lower part of 7 is in circulation.

When the fan 33 is accompanied by the cold provided with the evaporator 32, the compressor 29, and the like When driven by a cycle operation, the air sent by the fan 33 flows downward as indicated by the arrows in solid lines and broken lines in FIG. 2, and passes through the evaporator 32, where the air is cooled. Generate cold air. The cold air flows to the front side through the opening 34a, and flows upward in the supply duct portion 36. Then, the cold storage air outlet 37 for the lower side freezer container, the cold air outlet 38 for the upper side freezer container, and the cold air outlet 40 for the small freezer chamber are blown into the respective containers 19, 20, and 18. Further, the ice making chamber is blown out into the ice making chamber 5 by the cold air blowing port 39.

The cold air blown into the lower freezing container 19 from the lower freezing container through the cold air blowing port 37 passes through the lower freezing container 19 to cool the inside (the internal storage), and then passes through the gap G from the cold air inlet. The 41a, 42a are sucked in, and are again sent out by the fan 33 through the suction ducts 41, 42.

The cold air blown into the upper refrigerating container 20 from the upper refrigerating container cold air outlet 38 passes through the upper refrigerating container 20 to cool the inside, and then flows out from the upper surface opening and is sucked from the cold air suction ports 41a and 42a. And is again sent out by the fan 33 through the suction ducts 41, 42.

Then, the cold air blown out from the small freezer compartment 40 to the small freezer compartment container 18 is cooled by the inside of the small freezer compartment 18, and then flows out from the plurality of vent holes 18a and is taken out from the cold air intake port. The 41a, 42a are sucked in, and are again sent out by the fan 33 through the suction ducts 41, 42. The cold air supplied to the ice making chamber 5 is also supplied to the ice-making room, and is sucked from the cold air suction port 41a and returned to the cold air generating unit 30.

In addition, cooling is issued from a control unit (not shown) according to the cooling condition. When the command is switched, the cold air switching damper (not shown) is operated to switch the cold air supply to the main freezing compartment 7, the ice making compartment 5, and the small freezer compartment 6, and to the refrigerating compartment 3 and the vegetable compartment 4. Air conditioning supply. At this time, a dedicated evaporator or fan may be provided for the cold air supply to the refrigerating compartment 3 and the vegetable compartment 4.

In the above-described embodiment, the cold air blowing port 37 for the lower side freezer is provided so that the cold air is blown downward in the lower freezing container 19, and the cold air suction ports 41a and 42a are provided in the cold air blowing port for the lower side freezing container. The lowermost end of 37 is above.

According to the present embodiment, the cold air blown from the lower refrigerating container cold air outlet 37 is cooled in the lower freezing container 19, and then the cold air suction ports 41a and 42a are further above the cold air blowing outlet 37 of the lower freezing container. After being sucked and returned to the cold air generating unit 30, the cold air blown from the lower refrigerating container cold air blowing port 37 does not flow downward between the lower freezing container 19 and the main freezing chamber 7. That is, the airflow of the cold air as indicated by the arrow X of the two-dot chain line in Fig. 2 is not generated. As a result, no outside air (outside air) enters the inside of the main freezing compartment 7 or the inside of the heat insulating cabinet 2.

In other words, it is assumed that the cold air flow of the arrow X is generated, and the inside of the refrigerator of the connecting portion R1 or the connecting portion R2 is relatively negatively pressed outside the refrigerator due to the cold air flow, which may be as shown in the reference example. As shown in Fig. 5 and Fig. 6, the external air enters the inside of the heat insulating cabinet 2 or the main freezing chamber 7 from the small gap of the connecting portion R1 or the connecting portion R2 as shown by the arrow α. However, in this embodiment, The cold air flow indicated by the arrow X is not generated, so that the intrusion of the outside air is not caused. Therefore, it is also possible to prevent condensation from entering the inside of the refrigerator or the connecting portion R1 to the connecting portion R3 due to intrusion of outside air.

When a vacuum heat insulating panel is used for the heat insulating wall body, there is an advantage that the heat insulating wall body can be made thinner. However, since the vacuum heat insulating panel itself has a panel shape (plate shape), it is difficult to form a curved portion. shape. Therefore, when the heat insulating cabinet 2 is configured by the heat insulating wall body using the vacuum heat insulating panel, a plurality of heat insulating wall bodies are connected. Therefore, when the joint portion exists in the lower portion of the heat insulating cabinet, the intrusion of the outside air may occur. In particular, at this time, since the vacuum heat insulating panel is divided at the joint portion, a gap is formed between the vacuum heat insulating panels, and the intrusion of outside air is more likely to occur.

On the other hand, in the present embodiment, since the heat insulating wall body is configured to use a vacuum heat insulating panel, the outside air is easily invaded, but the air flow of the cold air does not face the main freezer compartment outside the upper freezing container 20. The lower side of 7 travels, thereby preventing the intrusion of outside air.

Further, according to the present embodiment, since the lower freezing container 19 has a structure that is non-porous except for the opening of the upper surface, the cold air blowing port 37 for the lower freezing container can be blown to the lower freezing container 19 . After passing through the lower side freezing container 19, the cold air flows directly from the upper surface opening to the cold air suction ports 41a and 42a, so that the formation of the cold air flow toward the lower side of the main freezing chamber 7 can be effectively prevented.

Further, in the present embodiment, the upper freezing container 20 is provided as a storage container independent of the lower freezing container 19, and a gap G is provided between the upper storage container 20 and the lower storage container 19, so that even the lower side is frozen. The upper side refrigerating container 20 is present on the upper side of the container 19, and the cold air supplied into the lower refrigerating container 19 can flow in the direction of the cold air suction ports 41a and 42a through the gap G.

Further, instead of or in addition to the configuration in which the gap G is provided, a configuration in which a vent portion is formed at the bottom of the upper side freezing container 20 may be employed.

Further, according to the embodiment, the cold air generating unit 30 adopts a configuration in which the fan 33 is disposed above the evaporator 32, and is configured such that cold air sucked from the cold air suction ports 41a and 42a passes through the fan 33. The evaporator 32 below the fan 33 is temporarily discharged forward, and then flows upward through the supply duct portion 36 to be blown out from the cold air outlets 37, 38, and 39. Therefore, the vertical size of the cold air generating portion 30 can be reduced.

In other words, when the supply duct portion facing downward is provided in the lower portion of the evaporator 32 of the cold air generating unit 30, and the cold air suction port is provided in the supply duct portion, the position of the cold air suction port is set to the lower side to be frozen. In the upper position of the container 19, the upper and lower dimensions of the cold air generating portion become extremely long, and the entire refrigerator is enlarged in the height direction. On the other hand, in the present embodiment, since the above configuration is employed, the vertical size of the cold air generating unit 30 can be reduced, and the entire refrigerator can be prevented from being enlarged in the height direction.

Further, according to the present embodiment, since the blocking portion 44 is provided, the blocking portion 44 prevents cold air from flowing from the opening of the upper portion of the lower freezing container 19 from which the cold air is blown toward the lower portion of the main freezing chamber 7, and therefore, is finally supplied to the lower side of the freezing. The cold air in the container 19 is directed only in the direction of the upper air intake ports 41a and 42a, and the cold air flow in the direction of the arrow X can be prevented, thereby further contributing to the prevention of intrusion of outside air.

In addition, a heat insulating material such as foamed urethane may be used as the heat insulating wall body of the heat insulating cabinet. At this time, it becomes the outer panel or the inner panel. The structure of the connection causes the joint to appear. In the present embodiment, when the connecting portion is located at the lower portion of the heat insulating cabinet, intrusion of outside air can be prevented.

Further, the bent portion at the bottom of the heat insulating cabinet is effective for forming the machine room, but the bent portion is not essential, and a structure in which only the joint portion exists at the bottom of the heat insulating cabinet may be employed.

The refrigerator according to the embodiment described above includes: a heat insulating cabinet body formed of a heat insulating wall body in a substantially box shape, a connecting portion of the heat insulating wall body at a lower portion, and a storage chamber formed therein; a storage container a bottom portion of the storage chamber is disposed in the storage chamber, and the upper surface is open; and the cold air generating portion is provided with an evaporator and a fan to generate cold air, and the cold air is blown out from the cold air outlet. The cold air suction port sucks the cold air, and the cold air blowing port is provided in such a manner that the cold air is blown into the storage container, and the cold air suction port is disposed above the lowermost end portion of the cold air blowing port. . According to this, in the refrigerator in which the connecting portion of the heat insulating wall body is present in the lower portion of the heat insulating cabinet, it is expected to suppress the intrusion of outside air from the connecting portion.
