Description

A refrigerator and a control method for the same

The present invention relates to a refrigerator and a control method of the refrigerator.

2. Description of the Related Art Generally, a refrigerator is a household appliance capable of storing an object such as food at a low temperature in a storage space formed in a cabinet. By cooling the inside of the storage space by using cool air generated through heat exchange with a refrigerant circulating in a refrigeration cycle, So that it can be stored in an optimal state.

The storage space may be divided into a refrigerator compartment or a freezer compartment according to a temperature range of the storage compartment. The storage space may be opened and closed by a door, and the user may open the door to put the object into or out of the storage space.

The refrigerator includes a top freezer type in which a freezing compartment is provided on the upper side in accordance with its shape, a bottom freezer type in which a freezing compartment is provided in a lower side, a side by side type in which the freezing compartment and the refrigerating compartment are provided side by side, And a French door type having a freezing chamber on the lower side.

Meanwhile, the refrigerator may be provided with a refrigeration cycle device for forming a refrigeration cycle for generating cold air.

The refrigeration cycle apparatus includes a compressor for compressing gaseous refrigerant at a high temperature and a high pressure, a condenser for cooling the compressed refrigerant to be condensed into a liquid state, an expansion valve for expanding the condensed refrigerant, And an evaporator.

The refrigerator may include a cooling fan for cooling the compressor and the condenser.

One side of the cabinet may be partitioned with the storage space, and a machine room in which the compressor, the condenser, and the cooling fan are disposed may be formed. In addition, the machine room may have an air inlet and an air outlet at one side thereof so that external air can be introduced and discharged.

By driving the cooling fan, the flow of air inside the machine room is forced, and the compressor and the condenser can be cooled by air flowing. When the cooling fan is driven, air can be sucked into the machine room through the suction port, and the air cooled inside the machine room can be discharged to the outside through the discharge port.

On the other hand, the cooling fan is generally controlled to be turned on when the compressor is driven and turned off when the compressor is stopped.

However, since the compressor is not sufficiently heated at the initial stage of driving the compressor, even if the cooling fan is driven, the cooling may not be effectively performed, and unnecessary power consumption may occur.

When the driving of the cooling fan is stopped when the compressor is stopped, the compressor may not be efficiently cooled and the temperature of the rebuilding may be too high to reduce the compression efficiency.

Therefore, in order to improve the efficiency of the refrigeration cycle and reduce the power consumption, a more efficient control method of the cooling fan is required.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator and a control method of a refrigerator which can prevent unnecessary power consumption and improve the efficiency of a refrigeration cycle through efficient control of a cooling fan for cooling a machine room.

A refrigerator according to an embodiment of the present invention includes: a cabinet forming a storage space; A refrigeration cycle device forming a refrigeration cycle and having a compressor and a condenser; A machine room formed at one side of the cabinet, in which the compressor and the condenser are disposed; A cooling fan disposed in the machine room for enforcing the flow of air for cooling the compressor and the condenser; A timer for accumulating the operation time and the stop time of the compressor; And a control unit for receiving the accumulated time information from the timer and controlling the operation of the compressor and the cooling fan, wherein the controller controls the operation of the compressor when the cooling fan is in a standby state So as to be driven later.

The control unit controls the cooling fan to stop after the driving is continued for a preset time T2 when the compressor is stopped.

The set time T1 and the set time T2 are the same time.

And a refrigerant valve provided on the refrigerant passage of the refrigerating cycle device for shutting off the refrigerant passage at an initial stage of driving the compressor and opening the refrigerant passage after a predetermined waiting time has elapsed, T1) is set to correspond to the waiting time of the refrigerant valve, and the cooling fan is driven when the refrigerant valve is opened.

A control method of a refrigerator according to an embodiment of the present invention is a control method of a refrigerator including a refrigeration cycle apparatus including a compressor and a condenser, and a cooling fan for enforcing the flow of air for cooling the compressor and the condenser, Wherein the compressor is driven for generation of the cooling fan, and the cooling fan is kept stationary; Determining whether a driving time of the compressor has reached a preset time (T1) in a control unit; And when the driving time of the compressor reaches the set time T1, the cooling fan is driven.

The compressor is stopped and the driving of the cooling fan is maintained; Determining whether a stop time of the compressor has reached a set time (T2) in the control unit; And stopping the cooling fan when the stop time of the compressor reaches the set time (T2).

The set time T1 and the set time T2 are the same time.

The set time T1 is a time of 30 seconds or more to 90 seconds or less.

The set time T2 is a time of 30 seconds or more to 90 seconds or less.

And a refrigerant valve provided on the refrigerant passage of the refrigerating cycle device for shutting off the refrigerant passage at an initial stage of driving the compressor and opening the refrigerant passage after a predetermined waiting time elapses, The time T1 is set to correspond to the waiting time of the refrigerant valve, and the cooling fan is driven when the refrigerant valve is opened.

Further, the compressor is a linear type compressor.

A control method for a refrigerator according to another embodiment of the present invention is a refrigerator including a refrigeration cycle apparatus including a compressor and a condenser, and a cooling fan for enforcing the flow of air for cooling the compressor and the condenser, The cooling fan is driven after waiting for a predetermined time when the compressor is driven, and the cooling fan is stopped for a predetermined time when the compressor is stopped.

In the control method of the refrigerator and the refrigerator according to the embodiment of the present invention, the following effects can be expected.

First, during the initial driving of the compressor, cooling may not be effective even if the cooling fan is driven as the temperatures of the compressor and the condenser are low. However, since the cooling fan is operated after the set time T1 has elapsed, inefficient power consumption of the cooling fan can be prevented.

Secondly, even after the compressor is stopped, since the cooling fan operates during the set time T2, the compressor and the condenser can be further cooled for a predetermined time. As the compressor is further cooled, it may become more fully cooled as the compressor begins to re-start. Thus, the compressor is prevented from reaching an excessively high temperature state, so that damage to the compressor can be prevented.

Further, since the condenser is further cooled, the condenser can be cooled more sufficiently than when the compressor starts driving again. Accordingly, as the temperature of the condenser is lowered, the condensing efficiency can be increased, resulting in an increase in the efficiency of the refrigeration cycle.

That is, since the cooling fan is delayed and stopped, power consumption is not increased, and the efficiency of the refrigeration cycle can be increased.

Thirdly, when the compressor is a linear type compressor, the cooling efficiency due to the driving of the cooling fan may be lowered as the temperature rises less due to a small load at the initial stage of the driving, (T1) has elapsed, it is possible to more effectively prevent inefficient power consumption.

Fourthly, there is provided a refrigerant valve for opening the refrigerant passage after a predetermined waiting time after the start of driving of the compressor so that the refrigerant flows after the refrigerant is sufficiently compressed by the compressor, So that the cooling is started when the refrigerant starts to flow and a load is generated in the condenser. Therefore, as the cooling is performed at the time of generation of the load of the condenser, unnecessary power consumption by driving at the time of occurrence of no load is prevented, and efficient cooling of the condenser is achieved.

For example, the refrigerant valve 150 may be provided at the outlet of the compressor 110. At the beginning of the operation of the compressor 110, the refrigerant passage is shielded and a refrigerant is compressed in the compressor 110, so that the refrigerant can not flow. When the refrigerant is compressed by the compressor 110 to a sufficient pressure, the refrigerant passage may be opened to discharge the refrigerant at a sufficient pressure.

The refrigerant valve 150 may be provided to be opened after a predetermined time elapses from the starting point of starting the compressor 110. Alternatively, the refrigerant can be provided to be opened when the outlet refrigerant pressure of the compressor 110 reaches a predetermined pressure or more.

Hereinafter, it is assumed that the refrigerant valve 150 is provided to be opened after a predetermined time elapses from the starting point of driving the compressor 110.

Meanwhile, a separate cold generating chamber having the evaporator 140 may be formed in the cabinet 11.

For example, the cool air generation room may be formed inside the rear wall of the storage space 12. The storage space 12 and the cool air generation room may be formed to communicate with each other. The air in the storage space 12 may be moved to the cool air generation chamber, cooled by the evaporator 140, and then supplied to the storage space 12 again.

The expansion valve 130 may be disposed in the cool air generating chamber and may be disposed on a pipe connecting the evaporator 140 and the condenser 120.

The refrigerator 1 may be provided with a machine room 14 in which the compressor 110 and the condenser 120 are disposed.

The machine room 14 may be formed at a lower portion of the refrigerator 1, or may be formed at a lower rear portion thereof.

The machine room 14 may be divided into the storage space 12 and the partition wall and provided as a separate insulated space from the storage space 12. The partition wall separating the machine room 14 and the storage space 12 is provided with a thermal insulation material so that the high temperature of the machine room 14 due to the operation of the compressor 110 does not affect the storage space 12. [ can do.

Meanwhile, the machine room 140 may include the compressor 110 and the cooling fan 20 for cooling the condenser 120.

The cooling fan 20 may be provided in the machine room 14 and may be provided to enforce the flow of air inside the machine room 14 for cooling the compressor 110 and the condenser 120.

The cooling fan 20 may force the external air to be sucked into the machine room 14 and may be forced to be discharged to the outside of the machine room 14 after passing the compressor 110.

The machine room (14) can be opened to the rear of the cabinet (11).

The rear opening of the machine room (14) can be shielded by the cover (16). The cover 16 may be detachably provided in the cabinet 11. [

The cover 16 may be formed with a suction port 161 through which external air is sucked into the machine room 14 and a discharge port 162 through which the air in the machine room 14 is discharged to the outside.

The suction port 161 and the discharge port 162 may be disposed on the left and right sides of the cover 16. A flow path through which the air moves may be formed between the suction port (161) and the discharge port (162) in the machine room (14).

Of course, the suction port 161 and the discharge port 162 are not limited to the embodiments of the present invention, and may be various positions in which external air can pass through the machine room 14, Lt; / RTI > For example, the suction port 161 and the discharge port 162 may be formed on the left and right sides of the machine room.

The compressor 110 and the condenser 120 are disposed on the air flow path between the suction port 161 and the discharge port 162 and can be cooled by being brought into contact with and exchanging heat with the moving air.

The cooling fan 20 is positioned on the air flow path between the suction port 161 and the discharge port 162 so that air is sucked from the suction port 161 side when driven to move to the discharge port 162 side. can do.

At this time, the cooling fan 20 may be positioned between the compressor 110 and the condenser 120. In addition, air may be sucked from the condenser 120 side to discharge air toward the compressor 110, so that the air can cool the condenser 120 and then cool the compressor 110.

The temperature of the compressor 20 is heated to a temperature higher than the temperature of the condenser 100 when the refrigeration cycle apparatus 100 is operated. Therefore, by first cooling the condenser 100 and then cooling the compressor 20 , So that cooling can be efficiently performed.

It is needless to say that the position of the cooling fan 20 is not limited to the present embodiment and that the air sucked into the machine room 14 through the suction port 161 is supplied to the condenser 120 and the compressor 110 sequentially Lt; RTI ID = 0.0 > and / or < / RTI >

For example, the cooling fan 20 may be disposed between the suction port 161 and the discharge port 162, and the compressor 110, the condenser 120, and the cooling fan 20 may be disposed in this order. Alternatively, the cooling fan 20, the compressor 110, and the condenser 120 may be disposed in this order.

The refrigerator (1) may include a temperature sensor (40) for measuring the temperature inside the storage space (12). The temperature sensor 40 may be provided in the storage space 12.

The temperature sensor 40 may be provided in each storage room so that the temperatures of the plurality of storage rooms can be measured.

The refrigerator (1) may include a timer (50) for counting the flow of time.

The refrigerator 1 may include a memory 60 for storing operation algorithm information of the refrigerator 1 and various data for controlling the refrigerator 1.

The refrigerator (1) may include a controller (30) for controlling the overall operation of the refrigerator (1).

The controller 30 may be electrically connected to the temperature sensor 40 to check the temperature information measured by the temperature sensor 40. Then, the timer 50 can be electrically connected to check the flow of time.

The control unit 30 may be electrically connected to the memory 60 to control the overall operation of the refrigerator 1 according to an algorithm stored in the memory 60. [

The controller 30 may be electrically connected to the compressor 110 and the cooling fan 20 to control the operation of the compressor 110 and the cooling fan 20.

The control unit 30 may control the operation of the compressor 110 according to an algorithm stored in the memory 60. [ At this time, the driving and stopping conditions of the compressor 110 can be variously applied to maintain the temperature of the storage space 12 within a required range.

Algorithms related to the operation of the compressor 30 for efficiently maintaining the temperature of the storage space 12 are variously disclosed in the known art, and a detailed description thereof will be omitted.

For example, the memory 60 may be provided with a set temperature value for driving or stopping the compressor 110. The control unit 30 may control the operation of the compressor 110 by comparing the set temperature value stored in the memory 60 with the temperature value measured by the temperature sensor 40.

When the temperature measured by the temperature sensor 40 is equal to or higher than a predetermined temperature, the control unit 30 drives the compressor 110 to operate the refrigeration cycle apparatus 100. When the refrigeration cycle apparatus 100 is operated, cool air is generated and supplied to the storage space 12, and the storage space 12 can be cooled.

When the temperature measured by the temperature sensor 40 is lower than a predetermined temperature, the controller 30 stops the operation of the compressor 110 and stops generating the cool air. Accordingly, the temperature of the storage space 12 can be maintained at an intended proper temperature.

Meanwhile, the controller 30 may control the driving of the cooling fan 20 to cool the compressor 110 and the condenser 120.

At this time, the controller 30 may control the cooling fan 20 to be driven after a predetermined time elapses when the compressor 110 is driven.

The cooling of the compressor 110 may not be effective even when the cooling fan 20 is driven as the temperatures of the compressor 110 and the condenser 120 are low. However, since the cooling fan 20 is operated after a predetermined time has elapsed, inefficient power consumption can be prevented.

In particular, the compressor 110 may be provided as a linear type compressor to improve compression performance. In the case of the linear type compressor, there is a characteristic that a comparatively small load is generated at the beginning of the driving, and a temperature rise is not large at the beginning of the driving.

In particular, in the case of a linear type compressor, the internal piston compresses the refrigerant by linear motion, and can be operated so that the linear motion radius is small at the initial stage of driving and gradually increases in the linear motion radius. Therefore, at the initial stage of driving, the starting pressure may be small, the load may be small, and the temperature rise may not be large.

Therefore, when the linear type compressor is applied, when the cooling fan 20 is driven at the initial stage of driving the compressor 110, the cooling effect of the compressor 110 by the cooling fan 20 is greatly reduced Which may result in unnecessary power consumption. However, since the cooling fan 20 is controlled not to be driven at the beginning of the operation of the compressor 110, inefficient power consumption can be effectively prevented.

Meanwhile, the control unit 30 may control the driving of the cooling fan 20 to be continued for a predetermined time after the compressor 110 is stopped. That is, after the compressor 110 is stopped, the driving of the cooling fan 20 is stopped after the cooling fan 20 is continuously driven for a predetermined time without stopping the cooling fan 20 immediately .

The compressor 110 and the condenser 120 can be further cooled for a predetermined time since the cooling fan 20 operates for a predetermined time after the compressor 110 is stopped.

As the compressor 110 is further cooled, it may become more fully cooled as the compressor 110 begins to re-start. Accordingly, it is possible to prevent the compressor 110 from reaching an excessively high temperature state, thereby preventing the compressor 110 from being damaged.

Further, since the condenser 120 is further cooled, the condenser 120 can be cooled sufficiently more when the compressor 110 starts to be driven again. Accordingly, as the temperature of the condenser 120 is lowered, the condensing efficiency can be increased, and as a result, the efficiency of the refrigeration cycle is increased.

As a result, by delaying and delaying the cooling fan 20, the efficiency of the refrigeration cycle can be increased without increasing the power consumption so as to use the power more efficiently.

Hereinafter, a control method of the refrigerator 1 will be described in detail with reference to the drawings.

FIG. 4 is a view showing the operation and stopping points of the compressor and the cooling fan according to the embodiment of the present invention, and FIG. 5 is a flowchart showing a control method of the refrigerator according to the embodiment of the present invention.

When the driving condition of the compressor 110 is satisfied, the compressor 110 is driven and the refrigeration cycle apparatus 100 can be operated.

For example, when the temperature of the storage space 12 becomes higher than the proper temperature, the compressor 110 may be driven.

In detail, the storage space 12 may be provided as a refrigerating chamber or a freezing chamber, and may be provided to maintain a required temperature range for refrigerating or freezing storage of food.

The control unit 30 may determine that generation of cool air is required and control the compressor 110 to be driven when the temperature measured by the temperature sensor 40 is equal to or higher than a preset reference temperature C1.

At this time, the reference temperature C1 may be an upper limit temperature value of the required temperature range of the storage space 12, and may be stored in the memory 60 and provided. If the user adjusts the temperature of the storage space 12 through the operation of the refrigerator 1, the temperature value of the reference temperature C1 may be adjusted accordingly.

Meanwhile, when the compressor 110 is driven, the cooling fan 20 can be kept stationary. [S100]

The control unit 30 may count the flow of time through the timer 50 when the compressor 110 starts driving.

Then, it is possible to judge whether or not the counted time has reached the predetermined set time T1.

At this time, the set time T1 may be set to a time of 30 seconds or more to 90 seconds or less.

Alternatively, when the refrigerant valve 150 is provided to be opened after a predetermined specific waiting time from the starting point of the driving of the compressor 110, the waiting time of the refrigerant valve 150 at the set time T1 As shown in FIG.

That is, when the refrigerant valve 150 is provided, the set time T1 may be set to a time from the starting point of starting the compressor 110 to the time when the refrigerant valve 150 is opened have. In this case, the cooling fan 20 may start driving when the refrigerant valve 150 is opened after the compressor 110 is driven.

At this time, the waiting time of the refrigerant valve 150 may be set within a range of 30 seconds or more to 90 seconds or less. [S210]

When the driving time of the compressor 110 does not reach the preset time T1, the controller 30 may control the cooling fan 20 to maintain the stopped state. That is, the driving switch of the cooling fan 20 can be controlled to be in an off state. [S230]

Meanwhile, when the driving time of the compressor 110 reaches the preset time T1, the controller 30 may control the cooling fan 20 to be driven. That is, the drive switch of the cooling fan 20 can be controlled to be in the ON state.

That is, the cooling fan 20 can be operated after waiting for a predetermined time after the compressor 110 starts to be driven.

When the cooling fan 20 is driven, the air in the machine room 14 is forced to flow, and the compressor 110 and the condenser 120 can be cooled by air. [S220]

Meanwhile, the control unit 30 may determine whether the compressor 110 has reached a stop condition, and may continuously indicate or stop driving the compressor 110.

The stopping criterion of the compressor 110 may be the surface temperature of the compressor 110, the temperature of the refrigerant at the outlet of the compressor 110, or the temperature inside the storage space 12 .

In detail, when the temperature of the compressor 110 is lower than the predetermined reference temperature C2, the control unit 30 determines that generation of cool air is not required and that the compressor 110 has reached the stop condition It can be judged.

At this time, the reference temperature C2 may be a lower limit temperature value of the required temperature range of the storage space 12, and may be stored in the memory 60 and provided. When the user adjusts the temperature of the storage space 120 through the operation of the refrigerator 1, the temperature value of the reference temperature C2 may be adjusted correspondingly.

Alternatively, when the surface temperature of the compressor 110 or the temperature of the refrigerant at the outlet of the compressor 110 is equal to or higher than a predetermined temperature, the controller 30 controls the compressor 110 to prevent the compressor 110 from overloading, ) Has reached the stop condition.

To this end, a temperature sensor for measuring the temperature of the refrigerant at the outlet of the compressor 110 or the surface temperature of the compressor 110 may be further provided. [S310]

If it is determined that the compressor 110 has not reached the stop condition, the controller 30 may control the driving of the compressor 110 and the cooling fan 20 to be maintained.

That is, by driving the compressor 110, cool air is continuously generated and supplied through the refrigeration cycle apparatus 100, and the compressor 110 and the condenser 120 are cooled by the cooling fan 20 The state can be maintained. [S330]

On the other hand, when it is determined that the compressor 110 has reached the stop condition, the controller 30 may control the driving of the compressor 110 to stop.

At this time, the controller 30 may control the driving of the cooling fan 20 to be continued. That is, when the compressor 110 is stopped, the cooling fan 20 is driven to further cool the compressor 110 and the condenser 120. [S320]

The control unit 30 may count the flow of time through the timer 50 when the driving of the compressor 110 is stopped.

Then, it is possible to judge whether or not the counted time has reached the predetermined set time T2. The set time T2 may be the same as the set time T1.

For example, the set time T2 may be 30 seconds or longer to 90 seconds or shorter. [S410]

When the stop time of the compressor 110 does not reach the set time T2, the control unit 30 may control the driving of the sikik cooling fan 20 to be maintained. That is, the compressor 110 and the condenser 120 may be further cooled. [S430]

On the other hand, when the stop time of the compressor 110 reaches the preset time T2, the controller 30 can control the cooling fan 20 to stop. That is, the drive switch of the cooling fan 20 can be controlled to be in the off state. [S440]
