The present invention relates to a refrigerator and a method of operating the same, and more particularly, even when opening the refrigerator by lowering the temperature in advance by changing the mode of the refrigerator to a rapid cooling mode in advance before the times of frequent door openings. The present invention relates to a refrigerator capable of preventing excessive rise in internal temperature and improving cooling efficiency and a method of operating the same.

In general, the refrigerator is provided with at least one storage compartment in which food is accommodated so as to freeze and refrigerate food, and one side of the storage compartment is open to store and take out food.

In addition, the front of the storage compartment is provided with a door for selectively opening or closing the storage compartment.

The user can open the door to take out or put food stored in the storage compartment.

On the other hand, when opening the door of the refrigerator, cold air flows to the outside, air at room temperature flows into the storage compartment, and the temperature of the storage compartment is increased.

Even if the refrigerator door is kept open for a long time, the stored food may be deteriorated.

Therefore, the related art discloses a technique of rapidly recovering a low temperature of a storage compartment by changing to a rapid cooling mode when the refrigerator door is opened to increase the temperature.

Accordingly, the present invention has been proposed to solve the above problems, and statistically, when the door is frequently opened, the mode of the refrigerator is switched to the rapid cooling mode before the frequent times of opening the door to lower the temperature in advance. In addition, an object of the present invention is to provide a refrigerator and a method of operating the same, which can prevent excessive rise in the internal temperature and improve cooling efficiency.

In order to achieve the above object, a storage chamber is formed and the refrigeration cycle is performed; A door rotatably installed on the main body; A door opening sensor for detecting whether the door is open; A temperature sensor for sensing a temperature in the storage compartment; And when the door is opened at the first number of times at a plurality of first number of times at a uniform time interval, whether the door is opened from the door opening detecting sensor. The number of openings of the door corresponds to the times, and the first number of times is arranged in order of decreasing number of openings of the door, and the predetermined number of times is set from the first number of times corresponding to the maximum number of openings. After extracting two times, the refrigerator comprises a microcomputer to switch the mode of the refrigerator to the rapid cooling mode before a predetermined time interval for each of the second number of times, and receives the temperature in the storage compartment from the temperature sensor Is provided.

In addition, when the temperature in the storage chamber sensed by the temperature sensor is less than the lower limit temperature of the rapid cooling mode, the microcomputer switches the rapid cooling mode to the normal cooling mode or no operation mode.

In this case, the lower limit temperature of the rapid cooling mode is lower than the lower limit temperature of the normal cooling mode.

The microcomputer may further include a memory, in which the first number of times and the number of openings of the door corresponding thereto are stored.

In this case, when the microcomputer stores the first number of times and the number of openings of the door corresponding thereto, the microcomputer detects that the door is opened continuously with a previous time of each first number of times.

1 is a perspective view of a refrigerator according to an embodiment of the present invention, Figure 2 is a block diagram showing the configuration of a refrigerator according to an embodiment of the present invention.

The refrigerator 100 has a storage compartment 110a formed like a conventional refrigerator, and includes a main body 110 on which a refrigeration cycle is performed, and a door 120 rotatably installed on the main body 110.

In particular, the refrigerator 100 according to the embodiment of the present invention includes a door opening sensor 130, a temperature sensor 140, and a microcomputer COM.

The door opening detection sensor 130 detects whether the door 120 is open. In addition, the temperature sensor 140 detects the temperature T1 in the storage compartment 110a.

The microcomputer COM first receives whether the door 120 is opened from the door opening sensor 140 at a plurality of first numbers of times at uniform time intervals.

For example, when the interval is 1 hour, whether the door 120 is opened or not is transmitted at a total of 24 hours at an interval of 1 hour. The interval of 1 hour above is just one example, and the interval can be freely set such as 6 hours, 10 minutes, 1 minute or 10 seconds.

Thereafter, when the door 120 is opened at the first number of times, the microcomputer COM corresponds to the number of openings of the door 120 at the first number of times, and the first number of times. After arranging the number of times in the order of decreasing the number of openings of the door 120, and extracting the second number of times by a predetermined number of times from the first number of times corresponding to the maximum number of openings, the second number The mode of the refrigerator 100 is switched to the rapid cooling mode before each predetermined time interval. For example, the number of times for determining the second number may be freely set to 1, 3, 5, 10, etc. according to the characteristics of the refrigerator.

In addition, the microcomputer M receives the temperature T1 in the storage compartment 110a from the temperature sensor 140.

Therefore, by changing the mode of the refrigerator 100 to a rapid cooling mode in advance of the times where the door 120 is frequently opened, the temperature is further lowered in advance to prevent excessive increase in the internal temperature even when the refrigerator 100 is opened. And the cooling efficiency can be improved.

In the embodiment of the present invention, it is preferable that a door switch is used as the door opening sensor 130.

In addition, when the temperature T1 in the storage compartment 110a sensed by the temperature sensor 140 becomes equal to or lower than the lower limit temperature T2 of the rapid cooling mode, the microcomputer COM may select the rapid cooling mode. Switch to cooling mode or no operation mode.

The reason for limiting the lower limit temperature of the rapid cooling mode is to prevent the food or the like stored in the storage compartment 110a from freezing or becoming too cold due to the temperature of the storage compartment 110a being excessively lowered.

At this time, the lower limit temperature T2 of the rapid cooling mode is set to be lower than the lower limit temperature T2 of the normal cooling mode.

In addition, the microcomputer COM may include a memory M, and the memory M may store the first number of times and the number of openings of the door 120 corresponding thereto.

At this time, when the microcomputer COM stores the first number of times and the number of openings of the door 120 corresponding thereto, the microcomputer COM is continuously connected to the previous time of each first number of times. When the door 120 is detected to be open, the number of openings of the door 120 to be stored may be multiplied by a weight.

The reason for the weighting in the case of continuously opening in storing the number of openings of the door 120 in this way means that the probability that the door 120 is kept open for a long time statistically before and after that time is high. This is because it is necessary to perform the operation in the rapid cooling mode in advance.

The microcomputer COM also includes a memory M, which corresponds to dates, the first number of times corresponding to the dates, and the first number of times. The number of openings of the door 120 may be stored, and the number of openings of the door 120 for each time may be stored by adding only the number of openings within a period from a few days ago to the present.

As such, the reason for ignoring the old data and summing only the number of door openings in the period from the last few days to the present is that the recent door opening habits have changed statistically, and in this case, it is more preferable to use the latest data than the old data. This is because the door opening habit can be accurately predicted.

In this case, the microcomputer COM opens dates in the memory M, the first number of times corresponding to the dates, and the door 120 corresponding to the first numbers of times. When storing the number of times, when it is detected that the door 120 is opened continuously with the previous time of each first number of times, the number of openings of the storing door 120 may be multiplied and stored.

3 is a view illustrating a time-temperature graph according to an operation of a conventional refrigerator and a time-temperature graph of a refrigerator operation according to an embodiment of the present invention.

3A illustrates a time-temperature graph according to a typical refrigerator operation, and FIG. 3B illustrates a time-temperature graph of a refrigerator operation according to an embodiment of the present invention.

In FIG. 3A, time t0 is a time at which the opening operation of the refrigerator door 120 is performed, time t1 is a time at which the refrigerator door 120 is closed, and time t2 is a normal lower limit temperature of the storage compartment 110a. The time at which the temperature T2 was reached is shown. In addition, in FIG. 3B, time t0 'is a time at which the opening operation of the refrigerator door 120 is performed, time t1' is a time at which the refrigerator door 120 is closed, and time t2 'is a storage room 110a. Represents the time when the temperature reaches the normal lower limit temperature T2.

As can be seen by comparing FIG. 3A and FIG. 3B, according to the refrigerator operating system according to the embodiment of the present invention, the temperature in the storage compartment 110a is lowered to T1 lower than T2 in advance when the door 120 is opened. When the refrigerator door 120 is kept open for the same time (t1-t0 = t1'-t0 '), the temperature rises to T3 which is lower than T4. Therefore, it can be seen that the time (t3'-t1 ') for recovering to the lower limit temperature T2 of the cooling mode is shortened compared to the time (t3-t1) for FIG. 3A.

4 is a flowchart schematically illustrating a method of operating a refrigerator according to an embodiment of the present invention.

Method of operating the refrigerator 100 according to an embodiment of the present invention, the step of detecting whether the door 120 of the refrigerator 100 is open (S210); Determining whether the door 120 is open at a plurality of first number of times at uniform intervals (S220); Adding the number of openings of the door 120 corresponding to the first number of times when the door 120 is opened at the first number of times (S230); Arranging the first number of times in the order of decreasing the number of openings of the door 120 and extracting a second number of times by a predetermined number of times from the first number of times corresponding to the maximum number of openings ( S240); And switching the mode of the refrigerator 100 to the rapid cooling mode before a predetermined time interval every second number of times (S250).

In addition, the operation method, the step of detecting the temperature (T1) in the storage compartment (110a) of the refrigerator; If the temperature T1 in the storage compartment 110a of the refrigerator 100 is detected to be lower than or equal to the lower limit temperature T2 of the rapid cooling mode, switching the rapid cooling mode to the normal cooling mode or the non-operating mode; can do.

In this case, the lower limit temperature T2 of the rapid cooling mode is set to be lower than the lower limit temperature T3 of the normal cooling mode.

The driving method may further include storing the first number of times and the number of openings of the door 120 corresponding thereto. In this case, when storing the first number of times and the number of openings of the door 120 corresponding thereto, when it is detected that the door 120 is opened continuously with a previous time of each first number of times. In this case, the number of openings of the storing door 120 may be multiplied and stored.

For example, when the time interval of the first number of times is 10 seconds, when it is detected that the door 120 is opened continuously with the time before 10 seconds, the door 120 is opened for 10 seconds or more. It can be regarded as retained, and can be stored by multiplying the number of openings of the time by 2, 3, and the like.

In another embodiment, the driving method may include storing dates, the first number of times corresponding to the dates, and the number of openings of the door 120 corresponding to the first number of times. It may further include, in this case, the number of opening of the door 120 for each time may be stored by adding only the number of openings within a period from a few days ago to the current date.

In addition, when detecting whether the door 120 corresponding to the dates, the first number of times corresponding to the dates, and the first number of times is open, the first number of times When it is detected that the door 120 is opened continuously with the previous time, the weight of the opening number of the door 120 to be stored may be multiplied and stored.

Effects expected in the refrigerator operating method according to the present embodiment have been already described in the description of the refrigerator, and thus repeated descriptions thereof will be omitted.

In addition, in the above method, the statistics were mainly used based on the number of openings of the refrigerator door, but the statistics could be effectively used even based on the continuous opening time. For reference, in the present invention, it is proposed to consider this by giving a weight to the number of openings added when a continuous opening time is detected.

According to the present invention, by changing the temperature of the refrigerator to the rapid cooling mode in advance before the times when the doors are opened frequently, the temperature is further lowered in advance, thereby preventing excessive rise of the internal temperature even when the refrigerator is opened, and improving the cooling efficiency. Can be improved.
