Description

{The refrigerator in which the freshness preservation period is expanded while the bacterial occurrence is controlled.}

The present invention relates to a refrigerator, and more specifically, to radiate electric charges to the inner space of the refrigerator to continuously vibrate water molecules in the storage to suppress the generation of bacteria and to maintain freshness for a longer period of time to extend the shelf life of each It is designed to adjust the amount of charge emitted according to the type of storage.

In general, a refrigerator is a device for storing food at a low temperature, and is an electrical appliance that is frozen or refrigerated depending on the state of the storage to be stored.

In particular, according to an embodiment, a freshness keeping compartment is formed separately between the freezing compartment and the refrigerating compartment, or a freshness keeping compartment is formed inside the refrigerating compartment so that stored goods can be kept fresh through the freshness keeping compartment.

However, in this refrigerator, the cold air below 0 degrees generated by the heat exchange method is moved to the inside of the freezing compartment along the first flow path to create ice inside, and the cold air from the freezing compartment is moved to the freshness holding compartment along the second flow path. Stored goods are kept fresh at a temperature between ~ 10 degrees, and cold air from the freshness keeping compartment is moved to the refrigerating compartment along the third flow path to keep stored items at a low temperature, and cold air from the refrigerating compartment passes through the fourth flow path. It is moved back to the freezer and configured to circulate.

Therefore, conventional refrigerators have a structural problem in that the freshness holding compartment is based on the circulation structure of cold air, but is inevitably affected by the freezing and refrigerating compartments. There was a problem with being thrown away.

In other words, the freshness storage compartment and the refrigerator compartment must maintain a certain amount of moisture to keep the stored goods fresh. Conversely, the freezer must be cooled in a dry state so that frost does not occur.

Therefore, at first, the freshness compartment can keep the stored fresh with sufficient moisture and coolness,

As time passes, the moisture in the freshness-keeping compartment is moved to the freezing compartment by the circulation structure of cold air, causing frost, and the freezing compartment cannot smoothly supply cold air to the freshness-keeping compartment due to frost. will be.

Furthermore, in the conventional refrigerator, when food is stored for a long period of time and bacteria such as mold are generated, there is a problem in that the cold air circulation structure spreads to the entire freezing chamber and the freshness maintaining compartment along each flow path, contaminating the stored food.

Therefore, the present invention is intended to keep stored items fresh while suppressing the generation of bacteria regardless of the circulation structure of cold air in a conventional refrigerator.

In particular, it is intended to maintain freshness for a longer period of time while suppressing the occurrence of germs by continuously vibrating the water molecules of stored objects by making the inner space into a battlefield filled with electric charge.

In addition, the present invention is to adjust the amount of electric charges emitted according to the type or characteristics of the stored products according to the moisture content of the stored products stored in the refrigerator or the freshness keeping compartment.
