Method for control cool air of refrigerator using to infrared rays sensor

The present invention relates to a cold air control method of a refrigerator, and more particularly, a track ball structure including a spherical drive body equipped with an infrared sensor and a cold air discharge port, and a drive body case into which the drive body is inserted. It is mounted between the shelf and the refrigerating compartment door part, and the drive unit rotates the inside of the case at a predetermined time, and senses the temperature of each object in the refrigerating compartment through an infrared sensor mounted on the drive unit. By discharging the cold air to the) side to maintain a uniform temperature distribution in the refrigerator through the rapid cooling of the new object, thereby relates to a refrigerator cold air control method to improve the overall performance of the refrigerator accordingly.

In general, the refrigerator is used to freeze or refrigerate food, and the like, and as shown in FIG. 1, the refrigerator 100 is nutrientd into the main body 100 and the main body 100 to freeze and refrigerate food. 110 and the refrigerating compartment 120, the freezer compartment door 130 and the refrigerating compartment door 140, which is mounted on the front of the main body 100 to open and close the freezer compartment 110 and the refrigerating compartment 120, and the freezer compartment 110 And refrigeration cycle devices that perform compression, condensation, and evaporation to form cold air required for cooling of the refrigerating compartment 120, and the cold air formed by the freezing cycle 151 of the upper rear side of the freezing compartment 110; A blowing fan 150 for forcibly blowing air into the freezing compartment 110 and the refrigerating compartment 120, and the partition wall 115 between the freezing compartment 110 and the refrigerating compartment 120 in communication with the blower chamber 151. A plurality of positions are formed at each shelf 170 of the refrigerating compartment 120. It is comprised by the cold air discharge port 160 which discharges cold air.

In such a refrigerator, the low-temperature low-pressure gaseous refrigerant is compressed to high temperature and high pressure, and the compressed high-temperature high-pressure gas phase refrigerant is cooled and condensed in the course of passing through the condenser and converted into a high-pressure liquid state. As the phase-changed refrigerant passes through a capillary tube (not shown), its temperature and pressure are lowered, and then it is continuously phase-changed into a low-temperature low-pressure gas state in an evaporator to take heat from the surroundings to cool the air around it. The air cooled through the evaporator as described above is formed by a plurality of cold air outlets 160 formed in the freezer compartment 110 and the partition walls 115 of the freezer compartment 110 and the refrigerating compartment 120 by the operation of the blower fan 150 located at one side of the evaporator. As the discharge circulates through the refrigerating chamber 120, the temperatures of the freezing chamber 110 and the refrigerating chamber 120 are lowered.

However, in the conventional refrigerator illustrated in FIG. 1, a temperature sensor (not shown) mounted at a specific portion of the refrigerating compartment 120 senses a temperature of a new load (food) accommodated in the refrigerating compartment 120 to detect the new load. Instead of intensively supplying cold air to the refrigerator, if the temperature sensor mounted on a specific portion of the refrigerating compartment 120 senses the temperature of the refrigerating compartment 120 itself and the temperature around the refrigerating compartment 120 is high, the refrigerating compartment 120 Since it is formed in a structure (see FIG. 2) that supplies cold air to the entire refrigerating compartment 120 through the cold air outlet 160 formed in the partition wall 115, that is, the periphery of the refrigerating compartment 120 as described above. When the temperature is increased, there is a big problem that the power consumption of the refrigerator is increased, such that the cold air is discharged from the cold air outlet 160 for a predetermined time in order to cool the ambient temperature of the entire refrigerating chamber 120.

In addition, when a new new load is stored in the refrigerator having a cooling structure, that is, the refrigerating chamber 120, which cools the entire refrigerating chamber 120 having an increased ambient temperature by using the cold air discharged through the cold air discharge port 160 as described above. Since the new load stored is cooled while lowering the ambient temperature of the refrigerating chamber 120 by the cooling method as described above, there is a big problem that the cooling rate of the new load due to cold air and the cooling capacity of the refrigerator are greatly reduced.

In order to solve the above problems, the present invention provides a shelf of a refrigerator having a track ball structure including a spherical drive body each equipped with an infrared sensor and a cold air discharge port, and a drive body case into which the drive body is inserted. And a driving unit rotates and drives the inside of the case at a predetermined time installed between the refrigerator compartment door part and the temperature of each object stored in the refrigerating compartment through an infrared sensor mounted on the driving unit. By comparing the set temperature of the refrigerating chamber and injecting cold air to the exact position of the high object (new object) among the objects stored in the refrigerating chamber to maintain a uniform temperature distribution in the refrigerator through rapid cooling, accordingly The goal is to improve performance.

An object of the present invention, the track ball structure is mounted between the shelf of the refrigerator and the refrigerating chamber door part by mounting a spherical drive body each equipped with an infrared sensor and a cold air discharge port, and a drive body case into which the drive body is inserted. Detects the temperature of each object in the refrigerating chamber through the infrared sensor of the refrigerator to be solved by the refrigerator cold air control method using the infrared sensor of the present invention to discharge the cold air to a high object (new object) to cool the object quickly. Will be described in detail below with reference to the accompanying drawings.
