Description

How to control the sleep operation of the refrigerator

The present invention relates to a control method of a refrigerator, and more particularly, to a sleep operation control method of a refrigerator in which a sleep operation is automatically entered according to a sleep pattern of a user without pressing a sleep operation key.

In general, a refrigerator is an electronic product used for keeping food fresh for a predetermined period of time. As shown in FIG. 1, the refrigerator is divided into a main body 10 and a freezer compartment for freezing and storing food in the main body 10. (11) and the refrigerating compartment 12 for refrigerating, the freezer compartment 13 installed at the front of the main body 10 to open and close the freezer compartment 11, and the refrigerating compartment door 14 for opening and closing the refrigerating compartment 12; It is largely composed of a freezing cycle for making cold air required for cooling the freezing chamber 11 and the refrigerating chamber 12, and cold air supply means for sending the cold air made in the freezing cycle to the freezing chamber 11 and the refrigerating chamber 12.

The refrigeration cycle of the refrigerator includes a compressor (not shown) for compressing a low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant, and converting the high-temperature, high-pressure gas refrigerant into a high-temperature, high-pressure liquid refrigerant. The main condenser (not shown), the capillary tube (not shown) for converting the high-temperature, high-pressure liquid refrigerant into a low-temperature, low-pressure liquid refrigerant, and the low-temperature, low-pressure liquid refrigerant to evaporate a low-temperature, low-pressure gas refrigerant The main body is composed of an evaporator (not shown) and a connecting pipe (not shown) that serves as a moving passage for the refrigerant while integrating the respective components.

Therefore, when the refrigeration chamber 11 is filled with the food for freezing and the refrigeration chamber 12 is supplied with the refrigerated food, the compressor is configured to receive a control signal from the controller to drive the compressor to form a low-temperature, low-pressure gas refrigerant. Compress with a high-temperature, high-pressure gas refrigerant.

The compressed high-temperature, high-pressure gas refrigerant is guided through the condenser and condensed into a high-temperature, high-pressure liquid refrigerant while passing through the condenser. This is rapidly converted into a low-temperature, low-pressure liquid refrigerant and then guided through a connecting pipe to pass through the evaporator is converted to a low-temperature, low-pressure gas refrigerant to evaporate, whereby the ambient air is heat exchanged by the evaporation of the evaporator Cold air is generated.

Thus, the cold air generated in the evaporator is supplied to the freezer compartment by the cold air supply means to cool the freezer compartment, so that the food stored in the freezer compartment is frozen and a portion is supplied to the refrigerating compartment 12 to cool the refrigerating compartment 12. As a result, food stored in the refrigerating chamber 12 is refrigerated.

Figure 2 is a block diagram of a refrigerator having a sleep driving key according to the prior art.

Referring to FIG. 2, a refrigerator having a sleep driving key according to the related art includes a door opening / closing detecting unit 20 that detects whether a door of a refrigerator is opened or closed, and a freezing chamber temperature detecting unit 21 that detects a predetermined temperature of a freezer compartment of the refrigerator. And a central controller 22 for controlling the entire system according to a predetermined temperature detected by the freezer compartment temperature detector, a ROM 23 for operating a program according to a control signal of the central controller 22, and a central controller. RAM 24 for storing the data selected in 22 and reading out the stored data, and controlled by the central controller 22 according to a predetermined temperature detected by the freezer compartment temperature sensing unit 21 and in the refrigerator. The compressor 25 compresses the low-temperature and low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant, and the high-temperature, high-pressure gas refrigerant generated by the compressor 25 includes a condenser (not shown), a capillary tube (not shown), and an evaporator ( Through a low-temperature, low-pressure gas refrigerant through The sleep operation key for inputting the sleep operation key when the user is taken into the freezer / refrigerator fan 26 and the central control unit 22 which converts the converted low-temperature and low-pressure gas refrigerant to the freezing and refrigerating chamber. (27), and the sleep operation display unit 28 to inform the user when the sleep operation key 27 is applied to the central control unit 22.

The refrigerator having the sleep driving key according to the related art configured as described above has a problem that the refrigerator enters the sleep operation only when the user presses the sleep driving key before entering the sleep.

Therefore, there is a hassle of pressing the sleep operation key before the user enters the water surface.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide a sleep operation control method of the refrigerator in which the sleep operation is automatically entered according to the user's sleep pattern without pressing the sleep operation key. Is in.

The characteristic of the sleep operation control method of the refrigerator according to the present invention is that, when the power plug of the refrigerator is connected to a power outlet, the refrigerator performs normal operation, and does the user press the sleep operation key while the refrigerator performs normal operation? Determining the number of times the sleep operation key is applied to the RAM and the number of times the sleep operation key is applied to the RAM of the central control unit; Checking the time and number of times of sleep and the step of automatically sleeping during the time when the sleep operation key is applied to the refrigerator automatically, according to the user's sleep pattern without the user pressing the sleep operation key. Driving is about to enter.

3, in the sleep operation control method of the refrigerator according to the present invention, when the power plug of the refrigerator is connected to a power outlet, the refrigerator operates normally (S101).

At this time, the central control unit of the refrigerator drives the compressor and the freezer / refrigeration chamber fan through the motor driving unit, respectively, to perform cooling operation.

Subsequently, it is determined whether the user presses the sleep operation key during the normal operation of the refrigerator (S102). When the sleep operation key is applied to the refrigerator, the sleep operation display unit installed on one side of the refrigerator turns on, and the central control unit sleeps. The time when the operation key is applied and the number of times the sleep operation key is applied are stored in the RAM (S103).

Then, by the control signal of the central control unit, (10 o'clock to 2 o'clock), (2 o'clock to 4 o'clock), (20 o'clock to 22 o'clock) (2 o'clock to 24 o'clock) at 10 hour intervals for 10 days C) Check the time zone during which the sleep operation key is most applied (S104).

Subsequently, the refrigerator automatically enters the sleep operation at the time when the sleep driving key is most applied (S105).

When the sleep operation of the refrigerator starts, the defrost inrush driving time is changed to a time zone other than the sleep time zone of the user.

After the sleep operation is completed, the refrigerator performs normal operation.

The sleep operation control method of the refrigerator according to the present invention has the effect of automatically entering the sleep operation according to the sleep pattern of the user without pressing the sleep operation key.

In addition, by deferring the defrosting operation of the refrigerator for a predetermined time when the user sleeps to achieve a comfortable sleep when the user sleeps.
