Home bar temperature automatic control device and method of refrigerator

The present invention relates to a home bar of a refrigerator, and more particularly, to an apparatus and a method for automatically adjusting a home bar temperature of a refrigerator to automatically adjust the amount of cold air introduced into the home bar according to the amount and temperature of the load put into the home bar.

In general, the parallel refrigerator constitutes the main body 1 in a manner in which the freezing compartment 2 and the refrigerating compartment 3 are arranged side by side with each other by a central insulating wall 4 as shown in FIGS. 1A and 1B. In the freezer compartment 2 and the refrigerating compartment 3, the front part 13 is provided with a door 13. The freezing chamber (2) and the refrigerating chamber (3) is to create a cold air in the premises by the operation of the refrigeration cycle to circulate it to freeze and refrigerated food, the refrigeration cycle is a refrigerant gas is maintained at a high pressure state It consists of a high pressure part which circulates, and a low pressure part which keeps and circulates a refrigerant gas in a low pressure state. The high pressure unit includes a compressor for converting low-temperature low-pressure gas refrigerant into a high-temperature high-pressure gas refrigerant, a condenser for converting the high-temperature, high-pressure gas refrigerant changed in the compressor into a liquid refrigerant of room temperature and high pressure, and a liquid refrigerant at room temperature and high pressure through the condenser. It consists of a dryer for dehumidifying. And a capillary tube for converting the liquid refrigerant of room temperature and high pressure dehumidified through the low pressure section into a liquid refrigerant of low temperature and low pressure, and an evaporator for absorbing external heat while changing the liquid refrigerant of low temperature and low pressure changed in the capillary into a gas state. It consists of an accumulator that blocks the vaporized liquid refrigerant from entering the compressor. In such a refrigeration cycle, the evaporator 7 is installed perpendicular to the cold air circulation path on the rear wall side of the freezing chamber 2 so as to exchange heat in the circulating air in the furnace to change to cold, and the cold air is on the upper side of the evaporator 7. The inside of the chamber is forced to circulate by the driving of the blower fan 8 installed in the blower fan and its blowing force. The circulated freezer compartment and the refrigerating compartment cold air are returned to the evaporator 7 side to be heat exchanged, and then discharged to the freezer compartment 2 and the refrigerating compartment 3 by driving a blower fan 8 to the freezer compartment 2 and The food inside the refrigerator compartment 3 is to be frozen and refrigerated, and for this purpose, freezing and refrigerator compartment suction ports 9A and 9B are formed at the lower side of the shroud 6 of the freezer compartment 2 and the refrigerator compartment 3. On the upper side, the freezing and refrigerating chamber discharge ports are sucked through the freezing and refrigerating chamber suction ports 9A and 9B to discharge the circulated air exchanged from the evaporator 7 to the freezing chamber 2 and the refrigerating chamber 3 again. (9C) 9D are formed. In addition, the guide tube 9E penetrates through the heat insulating wall 4 in the center so that the refrigerating chamber cold air sucked through the refrigerating chamber suction port 9B can be directed to the evaporator 7 installed in the rear wall side cold air circulation path 6 of the freezing chamber 2. ) Is installed.

In the parallel refrigerator configured as described above, first, the blowing fan 8 installed at the upper side of the freezing chamber 2 rear wall cold air circulation path 6 is driven, and the freezing chamber 2 and the driving unit are driven by the blowing fan 8. The freezing compartment and the refrigerating compartment air are sucked through the inlets 9A and 9B formed on the lower side of the shroud 6 of the refrigerating compartment 3 and flowed into the evaporator 7 installed vertically in the cold air circulation path 6. At this time, the refrigerating chamber air introduced into the refrigerating chamber suction port 9B is led to the cold air circulation path 6 of the rear wall side of the freezing chamber 2 through the guide tube 9E installed through the central insulating wall 4 and is the freezing chamber suction port 9A. It is introduced into the evaporator 7 with the freezer air sucked through the). The freezing and refrigerating chamber air introduced in this way is heat exchanged by the evaporator 7 and then the freezing chamber through the discharge ports 9C and 9D formed at the upper side of the shroud 6 of the freezing chamber 2 and the refrigerating chamber 3. (2) and the refrigerating chamber (3) is to be repeatedly performed continuously. On the other hand, the upper side of the refrigerator compartment door 5A is provided with a home bar 5C for taking out and eating food in the refrigerator compartment 3 without opening the refrigerator compartment door 5A as shown in FIGS. 2 and 3. have. The home bar 5C has a storage space 5E having a home bar case 5D therein, and is provided inside the refrigerating chamber door 5A, and the front part of the home bar case 5D is opened to open the refrigerator compartment door 5A. The opening and closing of the groove bar door 5G provided at the opening 5B side of the groove bar door 5G is opened and closed, and a cold air inlet 5F is formed at the upper side of the rear surface of the groove bar case 5D, so that the cold air inside the refrigerating chamber 3 is formed. It is configured to flow into the home bar case 5D.

However, in the conventional home bar structure of the refrigerator, the amount of cold air supplied into the home bar case is determined by the total temperature of the refrigerator compartment regardless of the type and size of the load put into the home bar case. In one case, a large deviation between the internal temperature of the home bar case and the refrigerating chamber temperature causes not only unevenness of the overall temperature of the refrigerating chamber, but also causes deterioration of the performance and reliability of the device as well as the refrigeration efficiency. Therefore, an object of the present invention is to be able to automatically adjust the amount of cold air flowing into the home bar according to the amount and temperature of the load put into the home bar.

And the refrigerator compartment door 5A is provided with a groove bar 10 so that the food in the refrigerator compartment 3 can be taken out and eaten even when the refrigerator compartment door 5A is closed, and the groove bar 10 is housed therein. A space bar 11 includes a home bar case 10A, which is provided inside the refrigerating compartment door 5A, and a front bar of the home bar case 10A is opened to be installed at the opening 5B side of the refrigerating compartment door 5A. The door 10B is opened and closed by opening and closing the door 10B, and a cold air inlet 12 is formed at an upper side of the rear side of the home bar case 10A so that cold air in the refrigerating compartment 3 flows into the home bar case 10A. It is configured to be. In the home bar of the refrigerator, the present invention is provided with a door 13 for opening and closing the cold air inlet 12 of the home bar case (10A) on the upper side of the home bar case (10A). The door 13 is installed on one side of the shaft 13A so as to be rotated up and down about one side, and a motor 14 generating a driving force by power supply is installed on the lower side of the shaft 13A. In addition, the operating unit 15 is provided between the motor 14 and the door 13 to receive the driving force of the motor 14 to rotate the door 13 up or down by mechanical operation. The home bar case 10A is equipped with a temperature sensor 16 so as to detect the internal temperature of the home bar case 10A.

The present invention configured as described above, first, the internal temperature of the home bar case 10A is sensed by the temperature sensor 16 mounted on the home bar case 10A.
