That is, the cold air discharged from the lower discharge port 321 may flow to the first half of the lower space 112 along the lower surface of the partition member 16, and evenly supply the cold air to the entire area of the lower space 112. This becomes possible. In addition, the air flowing up to the front of the lower space 112 flows to the bottom of the lower space 112.

Air flowing downward from the front of the housing member 17 may be moved backward through the spaced apart from the bottom of the housing member 17 and the bottom surface of the storage chamber 11, the lower suction port ( 341 and 342 may flow to the rear of the grill pan cover 300 through the second suction port 342.

In addition, the air flowing downward from the rear end of the lower space 112 may flow into the space between the accommodating member 17 and the grill pan cover 300, and the first one of the lower suction ports 341 and 342. It may flow to the rear of the grill pan cover 300 through the suction port 341.

Accordingly, the cool air inside the lower space 112 may flow into the space in which the evaporator 13 is accommodated without being accumulated in a specific region despite the arrangement of the accommodating member 17, and by the evaporator 13. It can be cooled again and then supplied again, allowing even cooling of the lower space.

On the other hand, it may have a different structure for more even cooling of the lower space (112).

15 is a cross-sectional view showing another example of a cold air supply structure in the lower space.

As shown, the partition member flow path 161 may be formed below the partition member 16. The partition member 16 flow path may be formed on the lower surface of the partition member 16, may be integrally formed with the partition member 16, may be configured separately from the partition member 16 and coupled to each other. have.

The partition member flow path 161 may be formed by the partition member duct 162. The partition member duct 162 may be formed over the entire bottom surface of the partition member 16, and may have a size corresponding to the bottom surface of the partition member 16.

The rear end of the partition member duct 162 may be opened and may contact the grill pan cover 300. In addition, the opened rear end of the partition member duct 162 may communicate with the lower discharge port 321.

In addition, a plurality of duct outlets 163 may be formed on the bottom surface of the partition member duct 162. The plurality of duct discharge holes 163 may be spaced apart in the front-rear direction, and may be evenly disposed on the entirety of the lower portion of the partition member 16. Therefore, cool air flowing along the partition member duct 162 may be evenly discharged from the upper surface of the lower space 112 to the entire lower space 112.

Therefore, the cold air can be supplied evenly in the entire region, as well as in the second half of the lower space 112 adjacent to the grill pan cover 300, and even cooling can be performed without a temperature deviation occurring in the lower space 112.

Hereinafter, the operation of the refrigerator 1 having the above structure will be described.

16 is a block diagram illustrating a signal flow for controlling the operation of the refrigerator. 17 is a view schematically showing the overall cold air circulation structure inside the storage compartment.

As shown in the drawing, the inside of the storage compartment 11 may be cooled by one evaporator 13 provided at the rear of the storage compartment 11. In particular, the interior of the storage compartment 11 may be divided into a space formed by the upper space 111, the lower space 112, and the accommodation member 17, and one evaporator 13 in each of these spaces. The cold air supplied from) may be supplied.

An upper temperature sensor 203 may be provided in the upper space 111, and a lower temperature sensor 350 may be provided in the lower space 112. In addition, an accommodating member temperature sensor 390 for detecting a temperature inside the accommodating member 17 may be further provided. Of course, if necessary, the housing member temperature sensor 390 for sensing the temperature of the housing member 17 may not be provided, and cold air may be configured to be supplied for a predetermined time.

The upper temperature sensor 203, the lower temperature sensor 350, and the accommodation member temperature sensor 390 are connected to the controller, and the controller 19 is the upper damper 440, the lower damper 450, and a blowing fan. 430 and the fan 370.

Accordingly, the inner spaces of the upper space 111, the lower space 112, and the storage member 17 may be independently maintained in temperature and independently controlled by the control unit 19.

In more detail, if it is determined that the temperature of the upper space 111 is unsatisfactory by the upper temperature sensor 203, the controller 19 drives the blowing fan 430.

In addition, the cold air generated by the evaporator 13 may be introduced into the air guide 400 through the shroud 411 by the driving of the blower fan 430. In addition, when the upper damper 440 is opened, the upper damper 440 passes through the rear flow passage 260, and cold air may be discharged to the upper space through the upper discharge port 204.

In addition, some of the cold air flowing along the rear flow path 260 may be discharged downward from the front of the upper surface 111 of the upper space 111 through the upper duct 280. Therefore, the upper space 111 is evenly cooled by the cold air discharged from the front and rear.

The cold air moved downward of the cold air introduced into the upper space 111 flows along the upper surface of the partition member 16 and flows into the return duct 500 through the upper suction port 205. . In addition, the return duct 500 discharges the introduced cold air from the lower side of the evaporator 13 or the rear side of the evaporator 13. The evaporator 13 cools the air discharged by the return duct 500 again.

The air cooled by the evaporator 13 again flows into the air guide 400, and the upper space 111 is formed through the upper damper 440, the rear flow path 260, and the upper duct 280. The inner side of the cold air circulation can be made, and the upper space 111 is continuously cooled. When the upper temperature sensor 203 senses that the temperature of the upper space 111 is lower than the set temperature, the blowing fan 430 is stopped.

On the other hand, if it is determined that the temperature of the lower space 112 is higher than the set temperature by the lower temperature sensor 350, the blower fan 430 is driven and the lower damper 450 is opened.

The cool air generated by the evaporator 13 by driving the blower fan 430 flows into the air guide 400 through the shroud 411, and passes through the lower damper 450 that is opened. It enters the lower duct 360. In addition, the cool air is directed to the lower discharge port 321 through the lower duct 360, and the cool air discharged from the lower discharge port 321 flows forward to cool the lower space.

The air discharged into the lower space 112 may be recovered to the lower suction ports 341 and 342 through the spaced space below or rear of the accommodating member 17 after cooling the lower space 112. .

The cold air flowing into the lower suction ports 341 and 342 is directed toward the evaporator 13 inside the grill pan cover 300 and may be cooled again while passing through the evaporator 13. The cool air cooled after passing through the evaporator 13 may be circulated while being supplied to the lower space 112 again through the air guide 400, the lower damper 450, and the lower duct 360.

The lower space 112 may be continuously cooled by the circulation supply of the cold air, and the driving of the blowing fan 430 is stopped when the temperature of the lower space 112 is lower than the set temperature.

On the other hand, the lower space 112 is partitioned by the partition member 16 into a space located below the upper space 111, some of the cold air in the upper space 111 may be introduced. The lower space 112 may be maintained at a lower temperature than the upper space 111 because the lower space 112 is a space in which cold air moved downward is located.

In addition, the upper space 111 is located above the lower space 112, and since the cool air discharged to the lower space 112 does not flow upward because of the characteristics of the structure, the lower space 112 and the high temperature Independent cooling will be possible while maintaining.

On the other hand, the fan 370 is driven when the temperature inside the accommodating member 17 is equal to or higher than a set temperature or when cooling within the accommodating member 17 is required. Since the fan 370 is located in front of the evaporator and blows air in the axial direction, it is possible to supply the cold air generated by the evaporator 13 toward the accommodating member 17.

In particular, since the opening of the housing member 17 and the housing member discharge port 331 are disposed adjacent to each other in a position facing each other, the cold air toward the housing member 17 by the driving of the fan 370 is substantially the lower portion. All of them may be supplied to the inside of the accommodating member 17 without being leaked to another area of the space 112.

The interior of the accommodating member 17 is a relatively narrow space, and may be maintained at a lower temperature than the lower space 112 due to cold air supplied to the inside of the space closed by the drawer cover 172.

The cold air introduced into the accommodation member 17 may be discharged to the outside through a space between the drawer 171 and the drawer cover 172 without a discharge hole provided separately, and the lower suction ports 341 and 342. Recovered through may be cooled again by the evaporator (13).

Continuous supply of cold air into the housing 17 allows the inside of the housing 17 to be cooled at a relatively low temperature and at a high speed relative to other spaces.

When the inside of the accommodating member 17 becomes below a set temperature or satisfies a set time or condition, the driving of the fan 370 is stopped and the cooling of the accommodating member 17 is completed.

The accommodating member 17 may be configured to cover the accommodating member discharge port 331 and the lower suction port 341 from the front in a mounted state. That is, when the accommodating member 17 is mounted, the accommodating member discharge port 331 and the lower suction port 341 are not exposed to the outside. To this end, the accommodating member 17 may be disposed on a bottom surface of the lower space 112, and an upper end of the accommodating member 17 may be configured to be located at least above the accommodating member discharge port 331. have.

Meanwhile, at least one of the upper space 111, the lower space 112, and the storage member 17 formed in the storage chamber 11 may be independently cooled and operated. Hereinafter, an independent operation state of each space will be described with reference to the drawings.

As shown in the drawing, in the operating state for cooling the upper space 111, the cooling operation of the lower space 112 and the storage member 17 is stopped. In addition, when the upper space 111 is cooled, only cold air of the upper space 111 flows into the space inside the grill pan cover 300 to exchange heat with the evaporator 13. Therefore, inflow or mixing of air in the lower space 112 and the inner space of the accommodation member 17 can be prevented. Therefore, cooling of the upper space 111 can be made quickly and efficiently, and it is possible to prevent the temperature of the lower space 112 and the receiving member 17 from being unintentionally changed.

In detail, in the state where the blowing fan 430 is driven to cool the upper space 111, only the upper damper 440 is opened and the lower damper 450 is closed. In addition, the fan 370 maintains a stopped state when the blowing fan 430 is driven.

 Therefore, the air forcedly flowed by the blowing fan 430 may be supplied only to the rear passage 260 and the upper duct 280 through the upper damper 440. In addition, the flow of cold air into the lower space 112 and the inner space of the accommodation member 17 may be blocked at the source.

On the other hand, in the state in which the partition member 16 is removed, the upper space 111 and the lower space 112 may be in a non-partitioned state, and the lower damper 450 may maintain the closed state. In this case, when the blowing fan 430 is driven, circulation of cold air may occur in the entire interior of the storage compartment 11, and the entire interior of the storage compartment 11 may be maintained at substantially the same temperature. The entire storage compartment 11 can be used as one storage space such as a refrigerator compartment of a general refrigerator.

Of course, the accommodating member 17 is provided in the storage compartment 11 to form a separate accommodating space in the storage compartment 11, and to supply the cold air to the accommodating member 17. It may be possible to control the interior to an independent temperature.

By this independent cooling operation, the supply of cold air to the upper space 111 can be concentrated, and the temperature of the upper space 111 can be cooled to a predetermined temperature quickly.

19 is a view schematically showing a cold air circulation state during a cooling operation of a lower space in the storage compartment.

As shown, in the operating state for cooling the lower space 112, the cooling operation of the upper space 111 and the storage member 17 is stopped. In addition, when the lower space 112 is cooled, only cold air of the lower space 112 flows into the space inside the grill pan cover 300 to exchange heat with the evaporator 13. Therefore, inflow or mixing of air in the upper space 111 and the inner space of the accommodation member 17 can be prevented. Therefore, cooling of the lower space 112 can be made more quickly and efficiently, and it is possible to prevent the temperature of the upper space 111 and the receiving member 17 from being unintentionally changed.

In detail, in the state in which the blowing fan 430 is driven to cool the lower space 112, only the lower damper 450 is opened and the upper damper 440 is closed. In addition, the fan 370 maintains a stopped state when the blowing fan 430 is driven.

 Therefore, the air forcedly flowed by the blowing fan 430 may be supplied only to the lower duct 360 through the lower damper 450. In addition, the flow of cold air into the upper space 111 and the inner space of the accommodation member 17 may be blocked at the source.

This independent cooling operation allows the supply of cold air to the lower space 112 to be concentrated, and it is possible to cool the temperature of the lower space 112 to a predetermined temperature quickly.

20 is a view schematically showing a cold air circulation state during the cooling operation of the housing member.

As shown, the cooling operation of the upper space 111 and the lower space 112 is stopped in the operating state for cooling the inner space of the housing member 17. Therefore, the air in the upper space 111 and the lower space 112 may be prevented from being introduced into or mixed with the evaporator 13 to exchange heat. Therefore, cooling of the inner space of the accommodating member 17 can be made more quickly and efficiently, and it is possible to prevent the temperature of the upper space 111 and the lower space 112 from being unintentionally changed.

In detail, in the state in which the fan 370 is driven to cool the accommodating member 17, both the upper damper 440 and the lower damper 450 are closed, and the blower fan 430 also stops. Will be maintained.

 Therefore, the air forcedly flowed by the fan 370 may flow forward and may be supplied only to the inside of the accommodating member 17. In addition, the flow of cold air into the upper space 111 and the lower space 112 may be blocked at the source.

This independent cooling operation allows the supply of cold air to the accommodating member 17 to be concentrated, and it is possible to cool the temperature of the inner space of the accommodating member 17 to a predetermined temperature quickly.
