Description
The present invention relates to a method for controlling the temperature of a refrigerator in a refrigerator, and more particularly, to a refrigerator having a refrigerator which comprises a freezer compartment and a refrigerating compartment by detecting a temperature thereof and selectively driving a compressor, And the temperature of the elevated freezer compartment and the refrigerating compartment is adjusted to a normal temperature within a short period of time.
The refrigerator is equipped with a refrigerator and a refrigerator to keep the foods to be stored for a long time in a fresh state.
In such a refrigerator, when the temperature of the freezing compartment or the freezing compartment rises when the door is opened or closed, if the changed temperature is lowered to the predetermined temperature within a short period of time, the food can be stored in a fresh state for a long time.
The conventional refrigerator has a separate control key for lowering the raised temperature to a predetermined temperature quickly when the temperature of the refrigerator compartment or the freezer compartment rises when the door is opened and closed.
Accordingly, when the user opens and closes the door of the refrigerator compartment or the freezer compartment and presses the control key, the compressor and the refrigerator fan or the refrigerator fan constituting the refrigerator operate to lower the temperature of the freezer compartment and the refrigerating compartment to a predetermined temperature in a short period of time .
However, the conventional refrigerator has a problem that it takes a long time to adjust the temperature of the refrigerating chamber and the freezing chamber to a normal temperature because the rapid control operation is not performed unless a separate control key for rapid cooling and freezing is pressed.
Accordingly, the present invention is directed to a refrigerator and a refrigerator which selectively open a compressor, a freezing fan, a refrigerator fan, or the like according to a sensed temperature change by sensing a temperature of a freezer compartment and a refrigerating compartment, So that the temperature can be adjusted to a normal temperature within a short time.

According to an aspect of the present invention, there is provided a method for controlling a rapid temperature control of a refrigerator, comprising the steps of: detecting a temperature of a freezer compartment and a refrigerating compartment; determining whether a change in the temperature detected in the first step is high; A second step of comparing the temperature change data with the temperature change data at the time of the normal control, and a second step of comparing the detected temperature change amount with the temperature change data at the time of the normal control, Mode to a third step of controlling the temperature of the freezing compartment or the freezing compartment to be decreased within a short period of time.
Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a refrigerator temperature control system according to the present invention. The refrigerator includes a first sensor 1 for sensing the temperature of the freezer compartment, a second sensor 2 for sensing the temperature of the refrigerator compartment, A third sensor 3 for detecting whether or not the doors of the freezing compartment or the freezing compartment are opened or closed, a temperature sensor for detecting a temperature change of the freezing compartment or the freezing compartment using data input from the sensors 1-3, A first relay switch (5-7) for performing a switching operation in accordance with a control signal of the control unit (4), and a second relay switch A compressor (8) operated by a power supplied according to an operation and compressing and outputting a refrigerant for lowering the temperature of a refrigerating chamber or a freezing chamber, and a power source supplied according to a switching operation of the second relay switch A refrigeration fan 9 for supplying the refrigerant outputted from the compressor 8 to the freezer compartment and a refrigerant circuit 9 which is operated by a power supplied according to the switching operation of the third relay switch 7, And a refrigeration fan (10) for supplying refrigeration air to the refrigerator compartment.
In addition, N1-N3 not described above are inverters, and D1-D3 are diodes.
FIG. 3 is a flowchart illustrating a control process of the refrigerator temperature control system according to an exemplary embodiment of the present invention. Referring to FIG. 3, A second step of comparing the temperature change data with the temperature change data at the time of normal control when it is determined that the change amount of the temperature is high as a result of the determination; The control mode is switched to the rapid control mode and the temperature of the freezing compartment or the freezing compartment is controlled to be decreased within a short period of time.
In the third step, when the temperature of the freezing chamber changes significantly, the fan for the freezing operation of the compressor is operated for about 90 minutes so that the temperature of the freezing chamber falls in a short time.
In the third step, when the temperature of the refrigerating compartment is changed, the compressor and the refrigerator compartment are operated at a maximum output until the refrigerating compartment temperature reaches a predetermined temperature
The operation of the refrigerator temperature rapid control method of the present invention will be described with reference to FIGS. 1 to 3. FIG.
First, when the refrigerator performs a normal operation, the first sensor 1 senses the temperature of the freezer compartment and outputs the sensed temperature to the controller 4. The second sensor 2 senses the temperature of the refrigerator compartment, And the third sensor 3 senses whether the door of the refrigerator compartment or the freezer compartment is opened or closed and outputs the result to the controller 4. [
At this time, the controller 4 senses a temperature change of the refrigerator compartment or the freezer compartment using data supplied from each of the sensors 1-3, and controls the compressor 8 so that the temperatures of the refrigerator compartment and the freezer compartment are always kept constant, ), The freezing fan (9), and the cooling fan (10).
The control operation of the controller 4 will be described in more detail as follows.
2 (A) shows the temperature variation of the freezing compartment and the refrigerating compartment during normal operation. When the temperature of the freezing compartment and the refrigerating compartment rises to a certain temperature (point A in FIG. 2 (A)), The temperature of the refrigerating compartment and the freezing compartment are lowered by turning off the compressor 8 and the fans 9 and 10 when the temperature is lowered to the specified temperature (point B in FIG. 2 (A) It can be seen that the rising rate and the falling rate of freezing room and freezing room temperature are constant by avoiding falling too much.
However, when external factors such as the door opening and closing of the user are generated, the temperature of the freezing room or the refrigerating room rapidly increases as in the T1 section of FIG. 2 (B).
The sudden increase in temperature means that the slope of temperature gradient is steep.
Therefore, the control unit 4 recognizes the temperature change of the freezing room by using the data inputted from the first sensor 1, recognizes the temperature change of the freezing room by using the data inputted from the second sensor 2, If it is determined that the rate of change of the temperature has changed by a large amount as in the period T1 in FIG. 2 (B), the temperature change data of the previously stored normal operation is compared with the currently sensed temperature change.
If it is determined that the detected temperature change amount of the refrigerating compartment or the freezing compartment increases by a predetermined amount or more compared with the temperature variation during normal operation, the control unit 4 switches the mode to the rapid control mode, So that it can fall to the prescribed temperature quickly.
That is, if the temperature change amount of the freezing compartment is rapidly increased as a result of the comparison, the controller 4 turns on the first relay switch 5 and the second relay switch 6 to turn on the compressor 8 and the freezing fan 9 The control unit 4 controls the first relay switch 5 and the third relay switch 7 so that the temperature of the freezing compartment is lowered to the predetermined temperature within a short period of time, To operate the compressor (8) and the refrigeration fan (10) so that the temperature of the refrigerating compartment is lowered to a predetermined temperature within a short time.
When controlling the refrigerating compartment in the above operation, the compressor (8) and the refrigerating fan (10) are operated with the maximum output so that the temperature of the refrigerating compartment falls in a short time.
The present invention detects the temperature of the freezing compartment and the refrigerating compartment and selectively drives a compressor, a freezing fan, a refrigeration fan, and the like appropriately according to a change in temperature sensed. The temperature of the freezing compartment and the refrigerating compartment increased by door opening / The temperature can be maintained.
