The present invention relates to a refrigerator, and more particularly, to a refrigerator having a latch switch device provided in a handle of a door to release a storage container from being coupled to a door, And a stopper device that allows the latch switch device to be released only when the door is closed.

Generally, a refrigerator discharges cold air generated by a refrigeration cycle including a compressor, a condenser, an expansion valve, an evaporator, etc. to lower the temperature of the inside of the refrigerator and freeze or refrigerate food or the like.

The refrigerator generally includes a freezer for freezing food or beverage, and a refrigerator for storing the food or beverage at a low temperature.

Such a refrigerator includes a top mount type in which a freezing chamber is disposed in an upper portion of a refrigerating chamber, a bottom freezer type in which a freezing chamber is disposed in a lower portion of the refrigerating chamber, and a freezing chamber in which a freezing chamber and a refrigerating chamber are connected to the left and right sides And a side by side type (side by side type).

The refrigerator cools the storage compartment such as the freezer compartment or the refrigerating compartment by using the refrigerant generated while exchanging heat with the refrigerant circulating in the refrigeration cycle. Therefore, the inside of the storage compartment of the refrigerator is usually maintained at a lower temperature than the outside.

The freezer compartment and the refrigerating compartment are provided inside a cabinet constituting a refrigerator body and are selectively opened and closed by a freezing compartment door and a refrigerating compartment door, respectively. The freezer compartment door and the refrigerator compartment door are rotatably mounted to a freezer compartment and a refrigerating compartment whose front surfaces are opened. Each door is provided with a gasket for sealing the inside of the compartment.

In recent years, in order to meet the demands of various consumers and to prevent cold loss due to frequent opening and closing of the door, an opening is formed in a door of a refrigerator compartment door or a freezer compartment and a home bar door is rotatably mounted on the refrigerator compartment door or the freezer compartment door Has been developed and used.

Such a home bar door is provided so as to provide a storage space in a space through which the door is opened, and to store or take out food stored therein by opening the home bar door.

For example, Korean Patent Laid-Open Publication No. 10-2011-0067952 discloses a side-by-side type refrigerator in which an opening is formed in a freezing chamber door, and a groove is formed in the opening to allow a stored product to be easily taken out.

The home bar includes a storage room capable of storing stored items and a home bar door for selectively shielding the opening. The home bar door is rotatably provided around the hinge part.

That is, the disclosed refrigerator includes a freezing chamber door for opening and closing the freezing chamber, and a home bar door for opening and closing the storage chamber of the home bar in the freezing chamber door.

The refrigerator compartment door or the freezer compartment door may be referred to as a "main door" and the home bar door may be referred to as an "auxiliary door".

The home bar door having an opening at an intermediate portion of the door of the refrigerator compartment or the freezer compartment and configured to pivot the home bar door up and down and a home bar door having a width equal to the width of the refrigerator compartment door to be rotatable relative to the refrigerator compartment door There is.

In the latter case, a home bar door formed to be equal in width to the refrigerator compartment door is sometimes referred to as a "magic door ".

In both of the above-described home bar doors, the main door is rotatably connected to the refrigerator main body with a hinge, and the auxiliary door is rotatably mounted on the main door.

The main door is provided with a gasket as a sealing member for sealing the freezing compartment and the freezing compartment at an inner edge portion of the main door which is in contact with the front surface of the refrigerator body.

Also, a gasket for sealing the storage space inside the groove door is provided at a portion of the inner edge of the auxiliary door in contact with the main door.

However, since the main door and the auxiliary door are provided with separate gaskets, there is a problem that the loss of cool air through the two gaskets increases, compared to a case where only one gasket is provided because there is no auxiliary door.

In addition, dew is formed on the front surface of the main body, which is a portion where the gasket is in contact with the front surface of the main door, by the temperature difference between the inside and the outside of the main door.

In this case, since two heaters are required to prevent dew formation, power consumption is increased accordingly.
