A cold air duct (8) formed in the dividing wall (22) to guide cold air to the temperature controller (4);

A shelf 9 assembled in the refrigerating compartment 7 and the freezing compartment 6 to accommodate food, fruit, vegetables, and the like;

A door 10 for opening and closing the freezer compartment 6 and the refrigerating compartment 7 in which the shelf 9 is assembled;

A plurality of door baskets 12 coupled to the inside of the door 10,

A home bar 11 coupled to the door 10 together with the door baskets 12 to secure an independent refrigerator compartment;

A cold air inlet 15 formed in the home bar cover 14 to introduce cold air into the home bar 11;

The groove bar cold air duct 23 formed in the dividing wall 22 for guiding the cold air to the cold air inlet 15 is configured.

Referring to the operation and effect of the prior art as described above are as follows.

First, the blowing fan 3 blows low-temperature air dropped by the evaporator of the refrigerator 1 to the freezing air outlet 5 of the freezing chamber 6 and the refrigerating chamber 7.

The cold air blown through the cold air discharge port 5 is discharged into the refrigerating chamber 7 to circulate the refrigerating chamber 7.

In addition, the cold air blown into the freezing chamber 6 by the blowing fan 3 is circulated through the freezing chamber 6.

At this time, the temperature controller 4 of the refrigerator 1 is kept at about -18 ° C because the freezing chamber 6 must be frozen for a long time by freezing water or meat, etc., the refrigeration chamber 7 is drinking water, vegetables, Keep fresh goods such as fruits, so they should be kept unfrozen, so keep it at around 3 ° C to minimize the deterioration of the goods.

However, since the articles stored in the refrigerating chamber 7 are articles such as drinks, vegetables, fruits, etc. that are frequently used by the user, the door 10 is also frequently opened and closed.

That is, when the user opens and closes the door 10 to eat a cold drink, all the low temperature air in the refrigerating compartment 7 is mixed with the high temperature air in the room, and the temperature of the refrigerating compartment 7 is increased. As described above, a lot of power was consumed by operating the refrigerator 1 to lower the temperature of the elevated refrigerator compartment 7 to a lower temperature.

Therefore, items such as drinks or water stored in the refrigerating compartment 7 frequently used by the user combine the home bar 11 to the inside of the door 10 in order to minimize the cold air loss of the refrigerating compartment 7 and separate the home bar. The door 17 was formed and stored.

In addition, the home bar 11, which is enclosed with the home bar cover 14 in the door 10 and secures an independent space, has a home bar cold air in which the cool air supplied to the freezing chamber 6 by the blowing fan 3 is formed in the separation wall 22. Passing through the duct 23 flows into the cold air inlet 15 formed on the side of the groove bar 11 to maintain the inside of the groove bar 11 at a low temperature.

However, in the cold air supply structure of the groove bar 11, low temperature cold air is not quickly supplied into the groove bar 11.

That is, when the user opens the home bar door 17 and takes out the drink in the home bar 11, the inside of the home bar 11 is mixed with the room temperature to increase the temperature.

In addition, when the user closes the home bar door 17, low-temperature cold air should be quickly supplied to the inside of the home bar 11, but since the cold air is supplied only from the cold air inlet 15 formed at one side of the home bar 11, the home bar ( It takes a long time for the internal temperature of 11) to become low temperature.

In addition, since the cold air is moved from the top to the bottom, the cold air inlet port 15 formed on one side of the home bar cold air duct 23 and the home bar 11 is formed horizontally so that the cold air of the low temperature inside the home bar 11 The cooling performance inside the groove bar 11 was lowered because it was not supplied quickly to the furnace.

In addition, when the user wants to use the goods in the refrigerating chamber, the door is opened to use the goods. When the door is opened as described above, the warm air from the outside flows through the cold air inlet through the cold air inlet so that the temperature inside the home bar is increased. Has a problem that heat loss occurs due to the rise.

The purpose of the present invention for solving the conventional problems and the like,

When the door is closed, a large amount of low temperature cold air is quickly supplied to the inside of the home bar, and when the door is opened, the outside air cannot be introduced into the home bar to improve the cooling performance of the home bar. to provide.

In order to achieve the above object, the present invention,

When the door is closed, the cold air inlet is opened to supply cold air flowing into the space between the inner wall of the door and the door basket to the inside of the home bar, and when the door is opened, the cold air inlet is closed to prevent outside air from entering the inside of the home bar. Combining the opening and closing plate to the cold air inlet can achieve the object of the present invention.

The configuration of the present invention will be described in detail with reference to Figs.

Cold air is discharged from the cold air outlet 105 to the left and right directions by the operation of the blower fan 103 of the refrigerator 101 and flows down into the space 118 between the door inner wall 116 and the door basket 112. Opening and closing plate 131 coupled to the cold air inlet 115 of the home bar cover 114 to flow into the inside,

Coupling means of the opening and closing plate 131 for coupling the opening and closing plate 131 to the cold air inlet 115,

When the door 110 is opened by the opening / closing operation of the opening and closing plate 131, the cold air inlet 115 is closed to prevent outside air inflow, and when the door 110 is opened, the cold air inlet 115 is opened. The opening and closing means of the opening and closing plate 131 that can supply the cold air into the home bar 111 was provided.

And, the coupling means of the opening and closing plate 131 was provided with a hinge shaft 131 formed on the opening and closing plate 131 is coupled to the hinge hole 133.

In addition, the opening and closing means of the opening and closing plate 131 and the first magnet 134 attached to the lower end of the opening and closing plate 131,

The second magnet 135 is attached to the separation wall having the same height as the first magnet 134 and the inner wall.

Referring to the operation of the present invention as described in Figures 3 to 7 as follows.

First, the blowing fan 103 blows low-temperature air dropped from the evaporator of the refrigerator 101 to the freezing air outlet 105 of the freezing chamber 107 and the refrigerating chamber 106.

The cold air blown through the cold air outlet 105 is discharged to the refrigerating chamber 106 to circulate the refrigerating chamber 106.

In addition, the cold air blown into the freezer compartment 107 by the blower fan circulates through the freezer compartment 107.

At this time, the temperature controller 104 of the refrigerator 101 is kept at about -18 ° C because the freezing chamber 107 freezes water or meat and keeps it for a long time, and the refrigerating chamber 106 includes drinking water, vegetables, Keep fresh goods such as fruits, so they should be kept unfrozen, so keep it at around 3 ° C to minimize the deterioration of the goods.

In addition, the user frequently finds a drink or cool water stored in the refrigerating compartment 106 to combine the home bar 111 inside the door 110 to minimize the loss of cold air in the refrigerating compartment 106 and separate home bar doors. (117) was formed to allow storage of the article.

In addition, in order to cool the inside of the groove bar 111 having an independent space as described above, the cold air inlet 115 must be opened to supply cold air.

Therefore, when the door 110 is closed, the second magnet 135 attached to the first magnet 134 and the separating wall 122 or the inner wall 124 of the opening and closing plate 131 coupled to the cold air inlet 115. Magnetic forces are generated because they face the same height with the same polarity.

In addition, the opening and closing plate 131 to which the first magnet 134 is attached is pushed into the groove bar 111 by the magnetic force generated in the first magnet 134 and the second magnet 135 so that the hinge shaft 132 is closed. It rotates to a predetermined angle as shown in Figure 6 to open the cold air inlet 115.

In addition, the opening and closing plate 131 rotated as described above guides the cold air flowing down into the space 118 between the door inner wall 116 and the door basket 112 and flows into the home bar 111 to thereby introduce the inside of the home bar 111. Cool down.

On the other hand, when the user opens the door 110 to use vegetables or fruits or other items, if the opening and closing plate 131 of the home bar 110 is in an open state, warm air from outside flows into the home bar 111. The internal temperature of the home bar 111 is increased.

In addition, when the door 110 is opened when the opening and closing plate 131 is open when the user closes the door 110, the interference occurs between the separating wall 122 or the inner wall 124 and the opening and closing plate 131. The opening and closing plate 131 should always be closed.

Therefore, when the door 110 is opened, the first magnet 134 attached to the opening and closing plate 131 does not generate magnetic force with the second magnet 135, and is attached to the lower side of the opening and closing plate 131. It rotates downward about the hinge axis 132 by the weight of the first magnet itself.

In addition, the opening and closing plate 131 is positioned in line with the home bar cover 114 as shown in FIG. 7 to close the cold air inlet 115.

Therefore, when the door 110 is opened, the cold air inlet 115 is closed to prevent heat loss due to external air flowing into the cold air inlet, and the separating wall 122 or the inner wall 124 when the door 110 is closed. In order to prevent the interference of the opening and closing plate 131.

In this way, the present invention combines the opening and closing plate with the cold air inlet formed on the left and right sides of the home bar cover, and when the door is closed, the cold air inlet is opened by the opening and closing plate to flow into the space between the door inner wall and the door basket.
