As a result, the restricting projection 154 comes into contact with the inner surface of one side of the pivoting restriction hole 127 when the pillar 110 is unfolded, so that the pivot angle is limited.

Since the restricting projection 154 is accommodated in the rotation restricting hole 127, movement of the pillar 110 in the longitudinal direction is restricted, and the pillar 110 can be prevented from being separated.

The guide protrusion 142 is guided by the slide rail 160 when the pillar 110 is lifted or lowered. The slide rail part 160 is fixed to the inside of the pillar 110 by a separate bracket and may be integrally formed inside the pillar 110.

The slide rail portion 160 is provided with a receiving groove portion 162 for receiving the locking protrusion 154 when the locking protrusion 154 and the cutout groove 152 coincide with each other as shown in FIG. The receiving groove portion 162 is formed at the lower end of the slide rail portion 160. The receiving groove portion 162 receives the restraining protrusion 154 when the filler 100 is folded, 110 are prevented from moving up and down.

Hereinafter, the function and effect of the sealing device of the side-by-side refrigerator according to the embodiment of the present invention will be described.

First, the assembly of the sealing device 100 of the side door refrigerator according to an embodiment of the present invention will be described. A guide protrusion 142 is formed inside the filler 110 divided into the front plate 114 and the case 112 Install it.

The upper end of the guide protrusion 142 protrudes from the top of the pillar 110 and is coupled to the slide rail 160 in the pillar 110 and is elastically supported by the restoring member 156.

The fixed portion 123 of the hinge bracket 122 is attached to the door 10 by a separate fastening member 129 and the rotary portion 124 is accommodated in the rotary groove 125 of the pillar 110. [ At this time, the rotation preventing part 126 is provided in the rotation groove 125 so that the rotation part 124 is inserted in the upper direction from the lower part of the rotation groove 125 and bound. At this time, the restricting protrusion 154 formed in the rotation part 124 is inserted into the rotation restricting hole 127 of the departure prevention part 126 to limit the rotation range of the pillar 110 around the rotation part 124, The pillars 110 can be prevented from moving up and down.

The remaining space of the rotation groove 125 after the rotation part 124 is engaged is covered by a hook cap 130 which is hooked to the lower part of the rotation groove part 125.

The rotation trench 125 is formed to be longer than the rotation portion 124 to easily engage with the rotation portion 124 and to cover the surplus space of the rotation trench 125 by the finishing cap 130,

Hereinafter, the operation of the filler 110 by opening and closing the door 10 will be described. The first filler 110 is located in the sealing position. In other words, the door 10 is in close contact with the rear surface between the opposed doors 10 so as to seal the inside thereof, thereby preventing the outflow of cold air.

When the door (10) is opened to store food in the refrigerator storage room, the door (10) is rotated around the door hinge and opened.

The guide protrusion 142 is guided along the guide groove 145 of the guide block 144 and the filler 110 is folded into a vertical state of the door 10 according to the guide of the guide groove 145, .

At this time, the restraining protrusion 154 of the rotation part 124 is accommodated in the receiving groove part 162 by the rotation of the pillar 110 as shown in FIG. 4 or 8, Can be fixed by the restricting portion (150). That is, the pillar 110 is pivoted about the rotation portion 124 of the hinge bracket 122 and the guide protrusion 142, which is separated from the guide block 144, is raised by the elastic force of the restoring member 156 The incision grooves 152 are shifted from the restricting protrusions 154 of the hinge portions 120 as the guide protrusions 142 are raised.

That is, when the locking protrusion 154 is received in the receiving groove 162, the locking protrusion 154 does not coincide with the locking protrusion 154 as the guide protrusion 142 rises, so that the pillar 110 is not rotated. Therefore, in the opened state of the door 10, the filler 110 can always maintain the fixed position.

At this time, since the restraining protrusion 154 is accommodated in the receiving groove 162, the up and down movement of the pillar 110 can be restrained, and separation of the pillar 110 can be prevented.

When the door 10 is closed in the state where the storage of the food is completed in the refrigerator storage room, the filler 110 is kept in the correct position and can be closed without interference from the other door 10.

When the guide protrusion 142 is inserted into the guide groove 145 of the guide block 144, the guide protrusion 142 is lowered by the contact as shown in FIG. The cutout groove 152 is aligned with the restricting protrusion 154 by the lowering of the guide protrusion 142 so that the pillar 110 is rotatable around the hinge portion 120.

4, the guide protrusion 142 is guided along the guide groove 145 of the guide block 144 to rotate the filler 110 to the sealing position. When the filler 110 is rotated to the sealing position, the front plate 114 of the filler 110 comes into close contact with the gasket of each door 10 to prevent the cool air from leaking out of the storage room through the gaps between the doors 10 have.

The upward and downward movement of the guide protrusion 142 due to the opening and closing of the door 10 can be accurately guided linearly by the slide rail part 160 provided inside the pillar 110. [

As described above, according to the sealing device of the side door type refrigerator according to the embodiment of the present invention, the pillars can always be positively positioned in the open state of the door, and the rotation of the pillars is selectively prevented to prevent the product from being damaged by malfunction And it is easy to maintain and repair because of easy separation and connection of pillars.
