In addition, the bent portion 15 is inserted into the side portion 9 of the lower duct 1 to be described later.

The lower duct 1 is a device for introducing air descending from the upper portion into the duct, and is installed to be spaced apart from the bottom surface of the inside of the refrigerator body.

The lower duct 1 includes a bottom surface 5, a bent portion 6 positioned behind the bottom surface 5, the hooking portion 3 positioned behind the bent portion 6, It consists of side portions (9) in which grooves or protrusions are formed in both sides of the lower duct (1) and in the front and rear directions of the lower duct (1).

The bottom surface 5 is configured to put the container on the top in a rectangular plate shape. It is preferable that a rib 7 is formed below the bottom surface 5.

The rib 7 is formed in plural, and an arc portion 8 is formed which connects the rib 7 and the front part of the rib 7 with each other. The ribs 7 and the circular arcs 8 are formed on the inlet side through which the air is sucked, and serve as guides through which air can be introduced.

The bent part 6 is connected to the bottom surface 5 and is formed in a curved shape to give elasticity when the hooking part 3 is inserted and to cover the hooking part 3.

Therefore, the hooking part 3 is not visible from the exterior when opening and closing the door, thereby ensuring a beautiful appearance.

The hooking part 3 includes a vertical part 11 connected to the vertical part of the bent part 6, a horizontal part 12 connected to the vertical part and formed in a horizontal direction, and the horizontal part 12. It is made of an inclined portion 13 connected to.

The inclined portion 13 is a portion which is fixed while being inserted into the upper duct 2 and is inclined to the first vertical surface a and the first vertical surface a, which are connected to the horizontal portion 12. A plurality of inclined surfaces (b, c) formed, and a second vertical surface (d) formed in the vertical direction of the inclined surfaces (b, c).

At least one hooking portion 3 should be provided, and in the present embodiment, two hooking portions 3 are fixed to the front surface of the upper duct 2.

The hooking portion 3 may be configured to protrude as long as the horizontal length of the bent portion (6).

The hooking portion 3 is preferably made of a material that can be bent or stretched by its elasticity.

The hooking part 3 may be inserted into the groove 4 of the upper duct 2 to facilitate detachment.

The side portion 9 is configured to be long in the rail type from the front to the rear of the lower duct 1 can be easily removable.

The side portion 9 is protruded to form a projection and a groove.

The protrusion is composed of a first protrusion 25 and a second protrusion 26.

The protrusion may be configured in the shape of a vertical plate with a long length.

In addition, the groove is composed of a first groove 28 and a second groove (29).

The first protrusion 25 is connected to a lower end of one side of the bottom surface 5 and is formed in a downward direction, and a first groove 28 is formed in the lower direction of the first protrusion 25. The second protrusion 26 is formed at the lower end of the first groove 28 to protrude. In addition, a second groove 29 is formed in the lower direction of the second protrusion 26.

As mentioned above, the groove formed in the lower end of the said processus | protrusion is a form formed continuously.

A stopper 10 is formed at the end of the side portion 9 of the lower duct 1.

The stopper 10 is formed to protrude in the lower direction of the bottom surface 5 at the end of the side portion (9). The stopper 10 has a circular arc shape when viewed from the front side, and in the present invention, two stoppers 10 are formed at both sides.

That is, the first protrusion 102 and the second protrusion 103 are inserted into the groove along the shape of the protrusion 15 and slide.

In the present invention, the hooking portion 3 is formed in the lower duct 1, and the groove 4 is formed in the upper duct 2, but may be configured to be interchanged.

In another embodiment of the present invention, the protrusions 101 may be formed in the main body 100, and the grooves 24 may be formed in the lower duct 1.

The main body 100 refers to a portion forming both side walls with respect to the front surface of the inside. The main body 100 is provided with a plurality of protrusions 101 spaced apart from each other in the vertical direction.

The protruding portion 101 is formed in the front-rear direction of the main body 100, and preferably has a rectangular shape so as to be easily inserted into the groove.

The protrusion 101 may be composed of a first protrusion 102 and a second protrusion 103.

The first protrusion 102 is formed to protrude from a lower end of the main body 100 and is formed of a vertical portion and a horizontal portion formed horizontally on the vertical portion.

The second protrusion 103 is formed upward from one side of the first protrusion 102 to the vertical portion. That is, the first protrusion 102 and the second protrusion 103 are configured to be coupled in the vertical direction.

The lower end of the lower duct (1) is preferably provided with a rib (7).

The ribs 7 are formed to extend in the front and rear directions of the main body 100 so as to form a passage through which cold air flows between the lower duct 1 and the bottom surface 5 inside the main body 100.

In addition, although four ribs 7 are formed, five to six may be formed. An arc portion 8 is formed which connects the rib 7 and the front part of the rib 7 with each other.

The arc portion 8 is bent in an arc direction and coupled to the rib 7.

The rib 7 is configured to be parallel to the front and rear direction of the lower duct 1, is formed to protrude in the lower direction of the lower duct 1, the end of the horizontal portion formed in connection with the circular arc (8) As the width increases, the width becomes wider and inclined.

The ends of the ribs 7 are formed in the shape of a quadrangle with an inclination formed at each corner.

The central portion 20 of the rib 7 is formed to be concave at a predetermined angle, and inclined portions are formed at both ends of the central portion 20. With the above structure, it is possible to minimize the resistance of the air to be sucked.

A support 22 is provided which supports between the ribs 7 and the ribs 7.

The support 22 is composed of a first support 22A and a second support 22B formed in a lower direction of the lower duct 1 on one side of the first support 22A.

The first support 22A is configured to be coupled to the bottom surface 5, and the first support 22A is formed to be parallel to each other in the left and right directions of the lower duct 1.

The second support 22B is formed in a quadrangular shape so as to connect between the first support 22A and the first support 22A, and both ends of the upper edge are formed to be inclined.

The ribs 7 and the arcs 8 are formed to be located at the inlet side through which the air is sucked, and serve as a guide through which air can be introduced.

The operation of this embodiment having the above-described configuration will be described below.

First, when the lower duct 1 slides toward the upper duct 2, the ribs 7 and the circular arcs 8 reach the bottom, and the stopper 10 is caught on the bottom.

In this case, the inclined portion 13 of the hooking portion 3 may be inserted into the groove 4 of the upper duct 2 so that the second vertical surface d may be coupled while contacting the upper duct 2. have.

Therefore, the cold air generated from the evaporator is sucked to form a cold air flow path through the ribs 7 of the lower duct 1, the cold air hit the edge of the upper duct 2 is transferred into the upper duct (2). As it supplies cold air into the storage compartment.
