Description

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

The present invention relates to a refrigerator, and to be more specific, it emits electric charges into the inner space of the refrigerator to continuously vibrate water molecules in the stored product to suppress the occurrence of bacteria, and to maintain freshness for a longer period of time to extend the storage period and to It is designed to control the amount of radiated charge according to the type of storage.

In general, a refrigerator is a device for the purpose of low-temperature storage of food,

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

However, in such a refrigerator, cold air below 0 degrees generated by the heat exchange method is moved into the freezing compartment along the first flow path to generate ice inside, and the cold air from the freezer is moved along the second flow path to the freshness storage compartment. The stored material is kept fresh at a temperature between ~ 10 degrees, and the cold air in the freshness maintenance compartment is moved to the refrigerating chamber along the third flow path so that the stored material is stored at a low temperature, and the cold air in the refrigerating compartment is stored at a low temperature through the fourth flow passage. It is moved back to the freezer and circulated.

Therefore, the conventional refrigerator has a structural problem in that the freshness retention compartment is affected by the freezing and refrigerating compartments based on the cold air circulation structure. There was a problem with throwing it away.

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

Therefore, at first, the freshness storage compartment can keep the stored items fresh with sufficient moisture and cool air, but

As time passes, the moisture in the freshness storage compartment is moved to the freezing chamber by the circulation structure of cold air, and frost occurs, and the freezer compartment becomes unable to smoothly deliver cold air to the freshness storage compartment due to frost, and its operating condition gradually deteriorates. will be.

Moreover, the conventional refrigerator has a problem in that when food is stored for a long period of time and bacteria such as mold occur, it spreads to the entire freezer and freshness compartment along each flow path due to the circulation structure of cold air, thereby contaminating the stored material.
