Refrigerator and home bar heater control method with home bar heater {Refrigerator with hombar-heater and control method of hombar-heater}

The present invention relates to a refrigerator equipped with a home bar heater and a home bar heater control method.

Generally, a refrigerator is a home appliance that allows food to be stored at a low temperature in an internal storage space that is shielded by a refrigerator door. The refrigerator cools the storage space by using cold air generated by heat exchange with a refrigerant circulating in a refrigeration cycle. Stored foods can be optimally stored.

Such refrigerators are gradually becoming larger and more versatile in accordance with the change of dietary life and the trend of luxury, and refrigerators of various structures considering the convenience of users have been released. Recently, a refrigerator having a separate home bar on the refrigerator door and which can easily take out stored foods including drinks is preferred.

In a refrigerator equipped with a home bar, there is a problem in that condensation occurs in the home bar door due to a temperature difference between the inside and the outside of the home bar door. To solve this problem, the home bar door is provided with a home bar heater.

Hereinafter, a method of controlling the home bar heater according to the embodiments of the present invention having the above configuration will be described with reference to the drawings.

5 is a flowchart illustrating a control method of a home bar heater according to an exemplary embodiment of the present invention.

Referring to the drawings, the components constituting the refrigeration cycle is operated by the application of power to cool the interior. Condensation may occur in the home bar door 300 according to humidity conditions when the temperature in the refrigerator drops below a predetermined temperature during cooling in the refrigerator and the temperature of the outside air is above a certain temperature.

That is, the cold air in the refrigerator is in contact with the rear surface of the home bar door 300 and is not leaked to the outside by the gasket 220 in close contact with the home bar door 300. However, the groove bar door 300 adjacent to the gasket 220 has a lower temperature at the rear surface due to conduction, and when the condition that the dew condensation occurs in contact with the outside is provided, the rear surface of the groove bar door 300 and the Moisture due to condensation is generated on the inner circumference of the corresponding groove bar frame 200.

When power is applied to the refrigerator 1, the moisture detection sensor 500 is also activated, and the moisture detection sensor 500 is between the home bar frame 200 and the home bar door 300, in particular, the gasket ( Water is detected in a portion corresponding to the outside of the 220. [S100]

At this time, in the method for determining whether water is detected, when the humidity sensor is used as the moisture detection sensor 500, the humidity measured by the humidity sensor continuously to set the measured humidity can be generated condensation When the value is reached, it is determined that moisture is detected and the home bar heater is operated.

In addition, when an electrode sensor is used as the moisture detection sensor 500, when moisture is generated between the home bar door 300 and the home bar frame 200, the electrode sensor may be electrically connected. The home bar heater 400 is operated by determining that moisture is detected at the moment of electrical connection.

In addition, when a capacitive sensor is used as the moisture detecting sensor 500, the dielectric constant of the capacitive sensor changes as moisture is generated between the home bar door 300 and the home bar frame 200. When the condensation reaches the set value which may cause condensation, it is determined that moisture is detected and the home bar heater 400 is operated.

The measured value detected by the moisture detecting sensor 500 is transmitted to the controller, and when the measured value determined that condensation may occur to the controller is transmitted, the home bar heater 400 is instructed to supply power. .

When power is applied to the home bar heater 400, the home bar heater 400 generates heat to remove moisture between the home bar frame 200 and the home bar door 300, and the home bar frame 200. Condensation between the home bar door 300 is prevented. [S200]

Meanwhile, the moisture detection sensor 500 continuously transmits the measured value continuously detected to the controller even when the home bar heater 400 is operated, and moisture of a predetermined value or less is detected by the moisture detection sensor 500. If the controller is to cut off the power applied to the home bar heater 400 will stop the heating of the home bar heater 400. [S300]

This process is continuously repeated as long as power is supplied to the refrigerator 1, and the condensation is maintained in the home bar door 300 or the home bar frame 200.
