5 is a flowchart illustrating a control method of a refrigerator having a storage room according to the present invention.

Looking at the control method of the refrigerator having a storage room according to the present invention with reference to Figure 5, the first step is to store the food desired by the user in the storage room 12, then determine whether the set temperature of the food is input, food When the set temperature is entered, set the input temperature to the set temperature (see S1, S2, S3).

At this time, the user puts the food to be stored at a specific temperature on the tray 16 inside the storage chamber 12, and then closes the storage chamber door 14 to seal the storage chamber 12, and the temperature input button Input the temperature of the food directly through (52).

Next, in the second step, if the set temperature of the food is not input in the first step, it is determined whether the food name is input, and if the food name is input, the optimum temperature corresponding to the input food is automatically set to the set temperature. See S5)

In this case, the user inputs a food name input to the storage room 12 through the food input button, and the input food name automatically sets the optimum temperature corresponding to each food in the microcomputer 40 to a set temperature.

Of course, the microcomputer 40 is stored in advance the optimum temperature corresponding to a variety of food, the optimum temperature is the optimum storage temperature for storing the freshest food or the most suitable food temperature for storing the most delicious food, the optimum temperature Optionally, one of the optimum storage temperature or the optimum eating temperature may be selected.

A time may be set and transferred to the microcomputer 40.

In general, the low temperature storage mode allows food to be stored within a low temperature temperature range for a long time, while the rapid cooling mode enables the food to be cooled to a cryogenic temperature for a short time.

For example, the low temperature storage mode enables to maintain the optimal storage temperature at which the food can be stored freshest at the set temperature, while the rapid cooling mode sets the storage temperature of the food in a short time or the eating temperature in a good state of eating. It is preferable to be able to maintain the temperature, and more preferably to maintain a shorter operating time in the rapid cooling mode than the low temperature storage mode.

Of course, each mode may be configured before setting the set temperature in the first and second steps.

Next, in the fourth step, the microcomputer 40 adjusts the temperature control means according to the set temperature set in the first and second steps and the set mode set in the third step, thereby cooling the inside of the storage chamber 12. (See S7).

At this time, the setting mode, the setting temperature, and the setting time set by the buttons 52, 54, and 56 are transmitted to the microcomputer 40 to be displayed on the display unit 60. While controlling the operation of the temperature control means such as the means 20, while controlling the amount of cold air supplied to the storage chamber 12 to be supplied to the storage chamber 12 during the operation time.

Specifically, in the low temperature storage mode and the rapid cooling mode, the microcomputer 40 controls the amount of cold air supplied to the storage chamber 12 according to a set temperature and an operating time, and the opening and closing degree of the cold air supply valve 24 is controlled. And it can be adjusted depending on the opening and closing, the food is cooled to the set temperature by the cold air.

Of course, the supply amount of cold air is set to be larger in the rapid cooling mode than in the low temperature storage mode, so that the operating time is relatively shorter in the rapid cooling mode than the low temperature storage mode to cool down to a set temperature.

In more detail, as the refrigeration cycle is operated, cold air is generated around the evaporator 8, and the cold air flows along the cold air circulation passages 22a and 22b to open the cold air supply valve 24. The food is stored in the storage compartment 12 is introduced into the storage compartment 12, and the cold air is cooled.

Next, when the setting mode made in the fourth step is completed, the fifth step informs the completion of the setting mode, and then determines whether food is to be withdrawn from the storage room 12, and when food is withdrawn from the storage room 12. The operation is completed (see S8, S9).

At this time, when each setting mode is completed so that the food inside the storage compartment 12 is at the set temperature, the display unit 60 notifies the user through text, sound, alarm, etc., and determines whether the storage door 14 is opened or closed. do.

In more detail, since the opening and closing sensor 30 is installed between the storage room 12 and the storage room door 14, when each mode is completed, the opening and closing sensor 14 is opened and closed to draw food. The signal is transmitted from the 30 to the microcomputer 40 to determine whether the food is withdrawn, and if it is determined that the food is withdrawn, the microcomputer 40 operates in relation to the cooling performed in the storage chamber 12. To exit.

Next, in the sixth step, the cold storage mode is automatically set when the food is not withdrawn from the storage room 12 in the fifth step, and the microcomputer 40 adjusts the temperature control means according to each cold storage mode. Allow cooling inside the storage compartment 12 (see S10 and S11).

In this case, the cold storage mode is to be made automatically when the food is not drawn from the storage room 12 after the low temperature storage mode or the rapid cooling mode is completed to keep the food from melting, the cold storage mode or rapid cooling The cold air supply means 20 is controlled so that less amount of cold air is supplied to the storage chamber 12 than in the mode so that the food inside the storage chamber 12 maintains the set temperature of the low temperature.

Of course, while the cold mode as described above receives the signal from the opening and closing sensor 30 to the microcomputer 40 to determine whether to withdraw the food, if the food is withdrawn from the storage room 12, the microcomputer ( 40 completely terminates all operations related to the cooling inside the storage chamber 12.

In the above, the present invention has been described in detail by way of examples based on the embodiments of the present invention and the accompanying drawings.
