Description

Method for control cool air of refrigerator using to digital camera

The present invention relates to a method of controlling a cold air of a refrigerator, and more particularly, by mounting an image device (digital camera) in a refrigerating compartment and storing the new object (load) acquired by operating the image device at every opening and closing operation of the refrigerating compartment door. Comparing and determining the image of the refrigerating chamber of the state before and the image of the refrigerating chamber of the state after being stored in the new object by discharging and cooling cold air to the new object stored in the refrigerating compartment, the temperature distribution in the refrigerator through the rapid cooling of the new object is uniform. By maintaining it, the present invention relates to a refrigerator cold air control method for improving the overall performance of the refrigerator.

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 the refrigerating compartment 120, and the cold air formed by the freezing cycle 151 of the upper rear of the freezing compartment 110. 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 is fixed. 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 configured as described above, the temperature sensor (not shown) mounted on a specific portion of the refrigerating compartment 120 is a new load through the temperature detection or image of the new load (food) accommodated in the refrigerating compartment 120. Rather than supplying cold air to the new load intensively by measuring the volume of the refrigerator, the refrigerating chamber 120 may sense the weights of the shelves 170 and the refrigerating chamber 120 itself in the refrigerating chamber 120 in which an object is stored. A cold air control method for discharging and blocking cold air in the inside, or as shown in FIG. 2, a temperature sensor mounted at a specific portion of the refrigerating compartment 120 senses the temperature of the refrigerating compartment 120 itself and determines the refrigerating compartment 120. The cold air control method for discharging and blocking cold air in the entire refrigerating chamber 120 is used according to the high and low temperature of the surroundings. As described above, the ambient temperature and weight of the refrigerating chamber 120 are increased by the object. In order to reduce the ambient temperature and weight of the entire refrigerating compartment 120, the refrigerator itself discharges cold air for a predetermined time, thereby lowering the temperature and weight of the refrigerating compartment 120. There is a big problem.

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 is to mount a video device (digital camera) in the refrigerating compartment before the storage of a new object (load) acquired by operating the image device at every opening and closing action of the refrigerating compartment door. By comparing and determining the image of the refrigerator compartment of the state and the image of the refrigerator compartment after storing the new object, the cold air is discharged to the new object stored in the refrigerator compartment so that the temperature distribution in the refrigerator is maintained uniformly through rapid cooling of the new object. Therefore, the purpose is to improve the overall performance of the refrigerator accordingly.

The object of the present invention is to install a video device in a refrigerating compartment, and when the opening and closing action of the refrigerating compartment door, the imager is operated to compare the images of the refrigerating compartment before and after storage of a new object, and to the new object stored in the refrigerating compartment. It can be solved by the refrigerator cold air control method using the imaging device of the present invention to discharge the cold air so that the object is cooled quickly, it will be described in detail with reference to the accompanying drawings.
