Description

Home bar temperature automatic control device of refrigerator and its method {TEMPERATURE AUTO CONTROL APPARATUS AND METHOD FOR HOMEBAR 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 forms 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 the heat insulating wall 4 in the center, as shown in FIGS. 1A and 1B. The front doors of the freezing chamber 2 and the refrigerating chamber 3 are provided. 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 section includes a compressor for converting a 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 by 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 this refrigeration cycle, the evaporator 7 is installed vertically on the rear wall side of the freezer compartment 2 so as to heat exchange the circulating air in the refrigerator to cold, and the cold air is a blower fan installed on the upper side of the evaporator 7. The driving of (8) and the blowing force thereof allow the inside of the chamber to be forcedly circulated. 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 9 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 circulating 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 is installed to penetrate 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 led to the evaporator 7 side installed at the rear wall side of the freezing chamber 2. .

In the drawings, reference numeral 6 denotes a cold air circulation path formed between the rear wall of the freezing chamber 2 and the refrigerating chamber 3 and the shroud 9.

In the parallel refrigerator configured as described above, first, the blowing fan 8 installed at the rear wall side upper side of the freezing chamber 2 is driven, and the freezing chamber 2 and the refrigerating chamber 3 are driven by the blowing fan 8. Air is sucked in through the suction ports 9A and 9B formed at the lower side of the shroud 9 and flows into the evaporator 7 side. At this time, the refrigerating chamber air introduced into the refrigerating chamber suction port 9B is introduced into the evaporator 7 side of the rear wall side of the freezing chamber 2 through the guide tube 9E installed through the central insulating wall 4. 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 9 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 refrigerating compartment door (5A) is provided with a home bar (5C) for taking out the food in the refrigerating compartment (3) without having to open the refrigerating compartment door (5A) as shown in Figures 2 and 3 is provided 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.
