An embodiment of the present invention relates to a refrigerator.

An embodiment of the present invention relates to a refrigerator, and more particularly, to a refrigerator and a method of controlling the same, by improving a control structure of a home bar heater provided in a home bar and separately controlling the home bar heater according to a temperature state inside and outside the home bar. .

In general, a refrigerator is provided with a plurality of storage compartments in which the food is accommodated so as to freeze or refrigerate the food, and one side of the storage compartment is opened to store and take out the food.

In addition, recently released refrigerators, it is common that the home bar is further installed on a part of the door to prevent the leakage of cold air more than necessary due to the opening and shielding of the door. Here, the home bar is a portion capable of taking out a drink or food inside the refrigerator compartment without opening the door of the refrigerator.

In addition, an opening of a predetermined size is formed in the refrigerator door so that food is stored or taken out through the home bar, and the opening of the home bar door may be rotatably coupled to the opening.

On the other hand, the temperature difference between the inside and the outside of the refrigerator is large. That is, in the case of the refrigerating chamber, a temperature of approximately 2 to 3 ° C. is formed inside the refrigerator, and an ambient temperature (about 15 to 25 ° C.) of an environment in which the refrigerator is installed is formed outside of the refrigerator.

Therefore, a heat insulating material may be inserted into the home bar door to prevent heat transfer due to the temperature difference between the inside and the outside of the refrigerator.

In addition, the home bar may be provided with a home bar heater to prevent condensation of moisture in the air around the home bar due to a temperature difference between the inside and the outside of the home bar.

On the other hand, since the refrigerator door has a small heat insulation effect at the lower end of the opening due to the installation structure of the home bar door, the refrigerator door is generally formed at a lower temperature than other positions of the opening.

However, the conventional home bar heater is provided to be adjacent to the home bar door along a portion of the refrigerator door to supply the same amount of heat. Therefore, there was a problem in which a particularly low temperature phenomenon appeared at the lower end of the opening among the peripheral positions of the opening in which the home bar door is installed.

In addition, due to the difference between the temperature of the lower end of the opening and the ambient temperature of the refrigerator, moisture in the air is condensed at the lower end of the opening, and condensed moisture forms in the refrigerator.

In this case, when the heat amount of the home bar heater is increased in order to increase the temperature of the lower end of the opening, more power is required than the required power, which increases the cost of using the power. In addition, there is a problem that other parts of the opening, that is, the temperature of the upper end and both side ends are also increased, thereby reducing the freezing efficiency inside the refrigerator.

The present invention has been proposed to solve the above problems, and improves the structure of the home bar heater provided in the home bar to uniformly form the temperature around the home bar by the heater and to provide a refrigerator to increase the efficiency of the heater. For the purpose of

In addition, it is an object to have a large number of heaters are arranged around the home bar door where the low temperature is formed to reduce the power consumption with uniform temperature formation around the home bar door.

In the refrigerator according to an embodiment of the present invention for solving the problems as described above, and a main body portion is formed cold storage chamber; and the refrigerator door is rotatably coupled to the body portion, the opening is formed in at least a portion; and A home bar door to selectively shield the opening; And a heater provided in the refrigerator door to prevent condensation of wet air according to a temperature difference between the inside and the outside of the home bar door, wherein the heater is arranged such that at least one side of the opening generates more heat than the other side. It is characterized by.

In addition, the refrigerator according to another embodiment of the present invention includes a main body portion in which a cold air storage chamber is formed; and a refrigerator door rotatably coupled to the main body portion; And a home bar provided on the refrigerator door and having an opening through which food is drawn out, wherein the home bar includes: a home bar door to selectively shield the opening; A home bar frame in close contact with the home bar door when the home bar door is closed; And a heater provided inside the home bar frame to supply heat, and arranged in multiple stages on one side of the home bar frame.

According to the present invention according to the above configuration, with respect to the opening of the refrigerator door in which the home bar door is installed, in particular, the heater having a large capacity is arranged at the lower end of the opening so that the temperature around the home bar can be uniformly formed. have.

Therefore, it is not necessary to increase the amount of heat generated in the entire heater in order to uniformly form the temperature around the home bar, thereby reducing the power consumption required.
