Description

[0001] The present invention relates to a refrigerator and a refrigerator,

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

Generally, a refrigerator is a household appliance that allows low-temperature storage of food in an internal storage space that is shielded by a door. To this end, the refrigerator is configured to cool the inside of the storage space by using cool air generated through heat exchange with the refrigerant circulating in the refrigeration cycle, thereby storing the stored food in an optimum state.

Such a refrigerator allows the temperature inside the refrigerator to be maintained at a predetermined temperature so that the food stored in the refrigerator can always be stored in the best condition. In order to maintain the set temperature, the inside must be sealed, and it is configured to have a structure capable of continuous cooling by supplying cold air using a refrigeration cycle.

The storage space in the furnace enables the cool air generated in the evaporator to be supplied to the interior space by driving the blowing fan, in order to maintain a constant temperature. At this time, the blowing fan is driven when the temperature in the furnace is higher than the set temperature, and the cool air is supplied to the storage space to cool the furnace. When the furnace temperature is lower than the set temperature, the blowing fan is stopped to stop the supply of cool air to the storage space.

Korean Patent Laid-Open Publication No. 1997-0070868 discloses a refrigerator in which a storage space is composed of a refrigerating chamber and a freezing chamber, and a freezing chamber is maintained at a set temperature by cold air generated in an evaporator provided in the freezing chamber. A damper is provided on the flow path of the cool air supplied to the refrigerating chamber, and the refrigerator is capable of supplying cold air so that the refrigerating chamber maintains the set temperature by opening and closing the damper.

The controller controls the damper to maximize the flow rate of cool air supplied to the refrigerating chamber in the case of a specific situation such as a sudden rise in internal temperature due to the first startup of the refrigerator or the heat load, And the damper is controlled so that the flow rate of cool air supplied to the damper is smaller.

Wherein the damper comprises: a first opening and closing member for opening and closing a cool air passage passing through the barrier; And a second opening and closing member selectively opening and closing an opening formed in the first opening and closing member smaller than the size of the cold air passage.

Wherein the damper comprises: a third open / close member for opening / closing a part of the cool air passage passing through the barrier; And a fourth opening and closing member that opens and closes the remaining part of the cool air passage, and the third opening and closing member is formed to be larger than the fourth opening and closing member.

The damper includes: a first damper that opens and closes a first passage opened in the barrier; And a second damper that opens and closes a second passage opened to the barrier with a size smaller than that of the first passage.

A control method of a refrigerator according to an embodiment of the present invention is a control method of a refrigerator having an evaporator in a freezer compartment and controlling the supply of cool air to the refrigerator compartment by a damper provided in the barrier, The refrigerator is operated to cool the freezer compartment to supply the cool air generated by the evaporator until the temperature of the freezer compartment reaches the lower limit temperature. In the freezing compartment cooling operation, When the temperature of the interior of the refrigerator reaches the upper limit temperature, the control unit determines the flow rate of cool air supplied to the refrigerating chamber through the damper to a maximum flow rate and a flow rate less than the maximum flow rate, And a cold storage room cooling operation for supplying cold air to the refrigerator compartment.

Wherein the control unit supplies cold air at a maximum flow rate through the damper in a specific situation in which the first startup of the refrigerator or a high temperature heat load is applied to the inside of the refrigerator, So that cold air is supplied.

The storage space inside the cabinet 10 is divided into left and right sides by the barrier 11 to form the freezing compartment 12 and the refrigerating compartment 13, respectively. The door 20 includes a freezing compartment door 21 and a refrigerating compartment door 22 so that a pair can be rotatably mounted on both sides of the cabinet 10. The freezer compartment door 21 and the refrigerator compartment door 22 may be configured to independently open and close the freezer compartment 12 and the refrigerating compartment 13.

A plurality of drawers and shelves for storing food may be provided in the freezing room 12 and the refrigerating room 13. A basket for storing food may be provided on the rear surface of the freezer compartment door 21 and the refrigerator compartment door 22. The freezer compartment door 21 may include an ice maker for making ice and a dispenser for dispensing ice made by the ice maker. A home bar may be provided in the refrigerator compartment door 22.

Meanwhile, although not shown in detail, a machine room partitioned from the storage space may be formed at the lower end of the cabinet 10. Inside the machine room, a compressor (31) constituting a refrigeration cycle and a condenser, a compressor (31) and a fan for cooling the condenser may be provided.

An evaporator 121 may be disposed at the rear of the freezer compartment 12 and a blowing fan 122 may be installed above the evaporator 121 to cool the freezer compartment 12 ) Or forcedly flow toward the refrigerating chamber (13). The evaporator 121 and the blowing fan 122 may be shielded by a grill pan forming a rear wall of the freezing chamber 12.

The barrier 11 is divided into the freezing chamber 12 and the freezing chamber 13 so that the freezing chamber 12 is provided with a freezing chamber 13 , And from the freezing chamber (13) to the freezing chamber (12).

A damper 40 is provided on the upper portion of the barrier 11 so that cold air generated by the evaporator 121 can be supplied to the refrigerating chamber 13 through the barrier 11, A return duct 112 is provided at a lower portion of the barrier 11 so that air in the refrigerating chamber 13 flows into the freezing chamber 12.

The freezer compartment temperature sensor 123 and the refrigerating compartment temperature sensor 133 are provided in the freezing compartment 12 and the refrigerating compartment 13 so that the freezing compartment 12 and the refrigerating compartment 13 are cooled .

That is, when the temperature inside the freezing chamber 12 is not satisfied, the damper 40 is closed and the blowing fan 122 is driven to cool the evaporator 121 into the freezing chamber 12, And then cooled. When the temperature inside the refrigerating chamber 13 is not satisfied, the damper 40 is opened and the cool air of the evaporator 121 can be supplied to the refrigerating chamber 13 through the damper 40 do. The refrigerating chamber 13 can be cooled to a predetermined temperature by the cool air supplied into the refrigerating chamber 13 and the air in the refrigerating chamber 13 can be returned to the freezing chamber through the return duct 112 have.

The damper 40 can be frozen in a state where the damper 40 is closed by the cold air of the evaporator 121, so that the damper 40 can be heated by the heater to prevent binding by freezing and to perform normal operation.

3 is a schematic view showing a structure of a damper which is a main constituent of the refrigerator.

As shown in the drawing, the damper 40 according to the embodiment of the present invention is configured to control the flow rate of the cooling air supplied from the freezing chamber 12 to the refrigerating chamber 13 through various structures.

3 (a), the damper 40 includes opening and closing members 41 and 42 for opening and closing the cool air passage 111 formed in the upper portion of the barrier 11. The opening and closing members 41 and 42 are configured to allow air having a different flow rate to pass therethrough.

In detail, the opening and closing members 41 and 42 may include a first opening and closing member 41 and a second opening and closing member 42. The first opening and closing member 41 may be formed to open and close the entire cool air passage 111 and the second opening and closing member 42 may be provided on the first opening and closing member 41, And the opening 411 formed in the opening and closing member 41 may be opened or closed.

Accordingly, the first opening and closing member 41 can determine the supply of cold air that can flow through the entire cold air passage 111, and the second opening and closing member 42 is smaller than the cold air passage 111 The supply of the cool air supplied through the opening 411 of the first opening and closing member 41 can be determined.

The size of the cool air passage 111 may be set to a size that can satisfy the flow rate of the cool air necessary for a specific situation such as an initial operation of the refrigerator 1 or a high temperature food or object entering the inside thereof . That is, it is possible to supply a sufficient amount of cold air so that the cooling performance is not deteriorated even under such circumstances, based on a specific situation.

However, operation in a specific situation, such as when a large amount of cold air is supplied by opening the first opening / closing member 41, may cause the relatively high temperature air of the refrigerating chamber 13 The temperature of the freezing chamber 12 may be increased to increase the driving time of the compressor 31.

Accordingly, in a general situation other than a specific situation, the second opening and closing member 42 is opened to supply relatively small amount of cool air to satisfy the storage temperature of the refrigerating chamber 13, and at the same time, the temperature of the freezing chamber 12 excessively Can be prevented.

Of course, the open / close members 41 and 42 may be configured such that a plurality of open / close members 41 and 42 are not opened and closed but one open / close member 41 and 42 are opened and closed, The flow rate of cool air supplied through the cool air passage 111 may be adjusted.

3 (b), the damper may be configured such that the two open / close members 43 and 44 open and close one cool air passage 111, respectively.

The opening and closing members 43 and 44 may be composed of a third opening and closing member 43 and a fourth opening and closing member 44 and may be arranged in parallel to each other. Therefore, the third opening and closing member 43 and the fourth opening and closing member 44 may be formed to have different sizes, and accordingly, the opening and closing areas of the cold air passage 111 may be different from each other.

Therefore, in a specific situation where a large amount of cold air is required, both the third opening / closing member 43 and the fourth opening / closing member 44 are opened to supply the maximum flow rate through the entire cool air passage 111 So that cool air of a flow rate is supplied to the inside of the refrigerating chamber 13 to effectively cool the refrigerating chamber 13 in a specific situation.

When a smaller amount of cool air than the maximum amount of cooling air is required, the third opening / closing member 43 having a relatively large size is opened so that a smaller amount of cool air than the maximum flow amount is supplied to the scavenge freezing chamber 13, ). In a general situation where a relatively small amount of cold air is required, the fourth opening / closing member 44 having a relatively small size is opened to cool the refrigerating chamber 13 with the least amount of cold air.

As the amount of the cold air flowing into the refrigerating chamber 13 decreases, the amount of the hot air flowing into the freezing chamber 12 through the refrigerating chamber 13 can be reduced. That is, it is possible to prevent the high-temperature air heat-exchanged in the refrigerating chamber (13) from flowing into the freezing chamber (12) to drop the temperature of the freezing chamber (12) drastically.

Of course, the number of the opening and closing members 43 and 44 is not limited to two, but may be made larger in order to control the flow rate.

3 (c), two cool air passages 111 are opened in the upper part of the barrier 11, and a damper 40 is provided in each of the cool air passages 111 to enable independent opening and closing Lt; / RTI >

In detail, the cool air passage 111 may include a first passage 111a and a second passage 111b, respectively, which are opened at an upper portion of the barrier 11. The first passage 111a is formed in such a size that cool air of a maximum flow rate that can be supplied when the refrigerator 1 is operated in a specific situation can be supplied and the second passage 111b is connected to the first passage 111a ) So that the cool air can be supplied at a flow rate smaller than the maximum flow rate under a general situation other than a specific situation.

The first passage 111a and the second passage 111b may be provided with a first damper 45 and a second damper 46, respectively. The first damper 45 and the second damper 46 are configured to individually open and close the first passage 111a and the second passage 111b so that cool air supplied in a specific situation is required for a maximum flow rate The first damper 45 is opened and the second damper 46 is opened when a smaller amount of cold air is supplied in a general situation.

Hereinafter, operation of the refrigerator according to the embodiment of the present invention will be described with reference to the drawings.

FIG. 4 is a graph showing changes in the operating state of the refrigerator with time.

As shown in the drawing, the refrigerating compartment temperature sensor 133 and the freezing compartment temperature sensor 123 provided in the refrigerating compartment 13 and the freezing compartment 12 measure the temperature in the compartment, 31 and the damper 40 so that the temperature in the hearth can be kept below the set temperature.

When the temperature of the freezing compartment 12 is detected by the freezing compartment temperature sensor 123 to reach the upper limit temperature T1, it is determined that the temperature of the freezing compartment 12 is unsatisfactory and the compressor 31 is driven do. The refrigeration cycle is activated by the operation of the compressor 31 and cold air is generated in the evaporator 121. The generated cold air is supplied into the freezing chamber 12 by the blowing fan 122 to cool the freezing chamber 12.

The freezing chamber 12 is continuously cooled by the operation of the compressor 31. When it is detected by the freezing room temperature sensor 123 that the temperature of the freezing chamber 12 has reached the lower limit temperature T2, It is determined that the temperature of the freezing chamber 12 is satisfied and the compressor 31 is stopped.

The operation of the compressor 31 is determined according to the temperature of the freezing chamber 12, so that the freezing chamber 12 can be maintained at a predetermined temperature or lower.

The refrigerating chamber 13 is supplied with the cool air generated by the evaporator 121 toward the refrigerating chamber 13 according to the operation of the damper 40 so that the refrigerating chamber 13 can be cooled to a predetermined temperature. Hereinafter, the operation of the refrigerating chamber 13 will be described in detail with reference to the drawings.

5 is a flowchart sequentially showing the operation of the refrigerator.

As shown in the drawing, the compressor 31 is driven to enable the cooling operation of the refrigerating chamber 13 while the freezing chamber 12 is being cooled.

When the temperature of the refrigerating compartment 13 reaches the upper limit temperature T3 by the refrigerating compartment temperature sensor 133, the damper 40 is opened to cool the refrigerating compartment 13, So that the cool air can be introduced into the refrigerating chamber (13).

At this time, the controller 30 determines whether the operation state of the refrigerator 1 is a special operation state. The special operation corresponds to the case where the refrigerator is firstly started after the refrigerator is first installed or after a power failure, or when a high temperature food or object is introduced into the refrigerator compartment (13) and the temperature in the refrigerator rises sharply.

If the control unit 30 determines that the operation state of the refrigerator 1 is a special operation state, the controller 30 controls the damper 40 so that the cool air of the maximum flow rate is supplied to the refrigerating chamber 13 . That is, the first opening / closing member 41 is opened or both the third opening / closing member 43 and the fourth opening / closing member 44 are opened or the first damper 45 is opened.

Accordingly, the cool air of the maximum flow rate can be supplied to the inside of the refrigerating chamber 13 through the cool air passage 111, and the refrigerating chamber 13 can be cooled at a high speed (section A of FIG. 4). The cool air supplied to the inside of the refrigerating chamber 13 through the upper portion of the barrier 11 is cooled through the return duct 112 under the barrier 11 after cooling the inside of the refrigerating chamber 13, 12). The cool air generated by the evaporator 121 may be directly discharged to the inside of the freezing chamber 12 to cool the freezing chamber 12.

On the other hand, if the control unit 30 determines that the operation state of the refrigerator 1 is a general operation state other than the special operation state, the amount of cool air supplied to the refrigerating chamber 13 is relatively small, Allow a small flow rate. That is, the second opening / closing member 42 may be opened, the fourth opening / closing member 44 may be opened, or the second damper 46 may be opened.

Accordingly, relatively small amount of cool air is supplied to the inside of the refrigerating chamber 13 through the cool air passage 111, and the refrigerating chamber 13 can be cooled at a relatively later speed. The cool air supplied to the inside of the refrigerating chamber 13 through the upper portion of the barrier 11 is cooled into the freezing chamber 12 through the return duct 112 under the barrier 11 after cooling the inside of the refrigerating chamber Is recovered. The cool air generated by the evaporator 121 may be directly discharged to the inside of the freezing chamber 12 to cool the freezing chamber 12.

On the other hand, the operation time of the refrigerating chamber 13 can be accumulated by the timer 32 when the refrigerating operation of the refrigerating chamber 13 is started. If the operation time of the refrigerating chamber 13 is equal to or longer than the preset time while the cool air having a relatively small flow rate is supplied into the refrigerating chamber 13 by the normal operation, 40) to be supplied to the refrigerating chamber (13).

That is, when the cooling operation of the refrigerating compartment 13 exceeds the set time, the heat insulating performance of the refrigerating compartment 13 is lowered, or the cool air is leaked due to the breakage of the gasket. The control unit 30 supplies the cool air to the refrigerating chamber 13 at a maximum flow rate to prevent the food in the refrigerating chamber 13 from being damaged.

If the operation time of the refrigerating chamber 13 has not exceeded the predetermined time, the controller 30 maintains a state in which the relatively small amount of cool air is supplied to the refrigerating chamber 13 by the damper 40.

The supply of cold air to the refrigerating chamber 13 may be performed until the temperature of the refrigerating chamber 13 detected by the refrigerating chamber temperature sensor 133 reaches the lower limit temperature T4. When the temperature of the refrigerating compartment is detected by the refrigerating compartment temperature sensor to reach the lower limit temperature T4, the controller closes the damper to stop the supply of cold air to the refrigerating compartment.

When the flow rate of the cool air supplied to the refrigerating chamber 13 is reduced, the cooling operation time of the freezing chamber 12 is reduced as shown in FIG. 4, so that the operation time of the compressor 31 can be reduced. The cooling operation time of the freezing chamber 13 can be shortened and the whole cycle can be shortened. Thus, the refrigerator compartment 13 and the freezer compartment 12 can be brought to a similar time to a dissatisfied period, thereby enabling efficient operation.
