DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having improved air-blowing efficiency and the like when air is blown by being divided into a plurality of ducts.

[0002]

2. Description of the Related Art Today, a refrigerator (including a refrigerator) is provided with an air blower for sucking air and blowing it from a plurality of locations.

FIG. 6 is a perspective view of a refrigerator provided with such a blower, and FIG. 7 is a view showing a sectional structure thereof.
The internal space of the refrigerator is partitioned by a refrigerator compartment side partition wall 15 and the like, and a refrigerator compartment 4, a freezer compartment 5, a vegetable compartment 6 and the like are formed,
Further, a plurality of shelves 19 are provided in the refrigerator compartment 4 so that various foods can be stored.

[0004] A refrigerator is a compressor 2 for compressing a refrigerant.
2. It has a refrigerant circuit consisting of a condenser for releasing heat and condensing the refrigerant, a decompression device for reducing the pressure of the refrigerant, an evaporator for evaporating the refrigerant to generate cold heat, and further circulating the air in the refrigerator to the evaporator. A blower is provided for exchanging heat with the refrigerant and discharging the air from a discharge port provided in each room.

In recent years, such refrigerators have been equipped with a refrigerator-side evaporator 25 for supplying cool air to the refrigerator room 4 and the vegetable room 6 and a refrigerator-side evaporator for supplying cool air to the freezer room 5 and the ice room 7. FIG. 7 shows such a case.

When two evaporators are provided in this manner, the refrigerator-side blower 1 in which the refrigerator-side evaporator 25 is installed is provided.
39 and a freezer-side blower 40 in which the freezer-side evaporator 26 is provided.

The outlets in the refrigerator compartment 4 correspond to the ceiling outlets 29 and the shelves 19 which are provided on the ceiling on the opening side and form a cool air curtain when the door of the refrigerator compartment 4 is opened. It is provided with a shelf outlet 30 and the like provided on the rear side of the refrigerator compartment 4 (the wall on the back side facing the door).

The vegetable compartment 6 is not provided with such an outlet, and cool air is supplied by the air in the refrigerator compartment 4 flowing into the refrigerator compartment side communication hole 17 provided in the refrigerator compartment side partition wall 15. It has become so.

Then, the air in the vegetable compartment 6 is drawn into the refrigerator compartment side blower 139 from the vegetable compartment intake port 32, and the air in the refrigerator compartment 4 and the vegetable compartment 6 is circulated.

On the other hand, the freezer compartment 5, the ice room 7, and the select room 8 are each provided with a freezer compartment side outlet 31 and the ice room 7, the select room 8, and the freezer room 5 are provided.
The air in the ice room 7 and the select room 8 flows into the freezing room 5 through the freezing room side communication hole 18 provided in the freezing room side partition wall 16 for separating the freezing room 5 from the freezing room 5. Air is sucked into the freezer-side air blower 40 from the room air inlet 33.

With such a configuration, the refrigerant compressed by the compressor 22 radiates heat in the condenser to condense, is decompressed by the decompression device, and is supplied to the refrigerator-side evaporator 25 and the freezer-side evaporator 26. . Then, here, heat exchange with the air circulated by the refrigerating room side blower 139 and the freezing room side blowing device 40 evaporates, and the air is cooled.

The cooled air is blown into the refrigerator compartment 4 by the refrigerator compartment blower 139 and is blown into the freezer compartment 5 and the ice compartment 7 by the freezer compartment blower 40.

FIG. 8 is an exploded perspective view showing a schematic configuration of the refrigerator-side blower 139, which comprises a cross flow fan 43 for flowing air and a duct for forming a flow path of the air.

The duct is constituted by a ceiling duct 35 communicating with the ceiling outlet 29, a shelf duct 36 communicating with the shelf outlet 30, and an intake duct 37 for returning air from the vegetable compartment 6 to the refrigerator compartment side evaporator 25. The intake duct 37 is formed
Inside, a refrigerator-side evaporator 25 is provided so as to close the passage. The cross-flow fan 43 is connected to the refrigerator-side evaporator 2.
5 is provided on the leeward side.

FIG. 9 is a schematic cross-sectional view of the refrigerator-side blower 139. FIG. 9A is a schematic view including the ceiling duct 35, and FIG.
(B) is a schematic diagram including a shelf duct 36.

With such a configuration, the cross flow fan 4
When 3 rotates, the air in the vegetable compartment 6 flows into the intake duct 37 via the vegetable compartment intake port 32, and passes through the refrigerator compartment evaporator 25 provided in the intake duct 37.

Then, the vehicle crosses the cross flow fan 43 and the fan case 41 causes the ceiling duct 35 and the shelf duct 36 to pass through.
And is blown out from each outlet.

[0018]

However, since the shelf duct 36 extends substantially perpendicular to the ceiling duct 35, it is necessary to change the direction of the air discharged from the cross flow fan 43 to a substantially right angle. There is a problem that a large pressure loss occurs and the thickness H of the fan case 41 must be increased.

That is, in the configuration shown in FIG. 8, the air discharged from the cross flow fan 43 is discharged in a uniform direction.

Therefore, this direction is, for example, the ceiling duct 35
If the ceiling duct 3
The air flowing into the shelf duct 5 may go straight, but the air flowing into the shelf duct 36 must hit the wall P (see FIG. 9) to change the direction of the flow path.

At this time, if the wall P is close to the cross flow fan 43, the wind pressure on the wall P increases, causing a large pressure loss and a decrease in air volume.

Of course, by increasing the distance between the wall P and the cross flow fan 43 and making the wall P a curved surface, the wind pressure on the wall can be reduced to reduce the pressure loss, thereby preventing a decrease in the air volume. However, in this case, there is a problem in that the thickness H of the refrigerating room side blowing device 139 becomes large and the storage space is pressed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator in which a duct is made compact to increase a storage space, and a pressure loss is reduced so that a large air volume can be obtained.

As can be seen from these figures, a gap is provided between the wall of the fan case 41 on the side of the ceiling duct 35 and the partition plate 51 to form a shunt channel 57 for diverted air.

As a result, the air in the vegetable compartment 6 is sucked into the intake duct 37 from the vegetable compartment intake port 32 by the suction force generated by the rotation of the intake fan unit 49, and the air passes through the refrigerator compartment side evaporator 25. Then, it is cooled and flows into the fan case 41 via the intake duct side intake port 54.

The air flowing into the fan case 41 traverses the intake fan section 49 and is discharged in the direction of the ceiling duct side outlet 55.

At this time, since the suction force due to the rotation of the branch fan unit 50 is acting on the branch channel 57, the suction fan unit 4

However, since the channel changes due to the suction force of the branch fan unit 50, the conventional air flows. As described above, the occurrence of a large pressure loss can be prevented, and the air blowing efficiency is improved.

Further, since the air is diverted by being sucked in this way, the distance between the wall on the side of the ceiling duct 35 in the fan case 41 and the cross flow fan 43 can be shortened, and the refrigeration chamber side The thickness of the blower can be reduced, so that the storage space is not pressed.

On the other hand, the air cooled by the refrigerator-side evaporator 25 is diverted as described above and flows to the ceiling duct 35 and the shelf duct 36.

The air flowing through the ceiling duct 35 is blown into the refrigerator from the ceiling outlet 29 to form an air curtain, and the air flowing through the shelf duct 36 is blown from the shelf outlet 30 into the refrigerator. Thereby, even when the door is opened and closed, it becomes difficult for outside air to enter the inside of the refrigerator, so that the cooling effect is enhanced and the refrigerator compartment is uniformly cooled.

The air blown out to the refrigerator compartment 4 in this way is supplied to the refrigerator compartment side communication hole 17 provided in the refrigerator compartment side partition wall 15.
, And flows into the vegetable compartment 6 and returns to the refrigerator compartment side blower 39 from the vegetable compartment intake port 32.

The ceiling of the vegetable room 6 has baffles 20
The air flowing in through the refrigerated compartment side communication hole 17 directly blows on vegetables and the like stored in the vegetable compartment 6 to prevent drying and freezing of the vegetables and the like.

As described above, by using the air blower having a small thickness as the cooler-side air blower 39, the storage space such as the cooler room 4 is not squeezed, and the large capacity can be obtained without increasing the size of the housing. And the pressure loss of the diverted air is reduced, so that the power consumption can be reduced and the economy is increased.

Next, another embodiment of the present invention will be described with reference to the drawings. The same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

In the above embodiment, air from the intake duct 37 is taken into the intake fan unit 49, discharged from the intake fan unit 49 and flows into the ceiling duct 35, and a part of the air flows through the branch channel 57. In this configuration, the air is sucked into the distribution fan unit 50 and divided into the shelf duct 36.

The tongue 5 facing the ceiling duct 35
2 and the tongue piece 52 facing the shelf duct 36 are provided at different positions, and these are provided at positions substantially orthogonal to each other.

As a result, air from the cross flow fan 43 facing the ceiling duct 35 is discharged in a direction substantially perpendicular to the intake duct 37, and air from the cross flow fan 43 facing the shelf duct 36 flows to the intake duct 37. The ink is discharged in a substantially parallel direction.
