Fig. 4 is a rear view of the back shape of the door gasket of the refrigerator compartment door equipped with an ice maker according to the present invention, and Fig. 5 is a diagram of the installation structure of the heat insulation duct and the support bracket of the refrigerator compartment door equipped with an ice maker according to the present invention Partial exploded perspective view. the

It can be seen that the door gasket 224 protrudes forward/rearward and is recessed in the shape of the inner surface of the refrigerator compartment door 220 as seen from the rear surface structure of the door gasket 224 . the

The door liner 224 forms the refrigerator door 220 in combination with the casing 222 . Furthermore, in order to prevent loss of cold air inside the refrigerator compartment 200 through the refrigerator compartment door 220, a foam E is filled between the outer shell 222 and the door gasket 224 to form a heat insulating layer. Since the temperature inside the ice-making compartment 400 is different from the temperature inside the refrigerating compartment 200, heat insulation between the ice-making compartment 400 and the refrigerating compartment 200 is required. And the concave part should be filled with foam E. the

In order to form the ice making room 400, a heat insulating duct made of a heat insulating material is installed on the side of the door liner 224 corresponding to the outside of the ice making room 400, which is recessed backward (with reference to FIG. 4 ). 440. the

The heat insulation pipe 440 is used to guide the cold air between the cold air pipe 120 on the side of the main body 100 and the ice making chamber 400, and the door liner where the supply port 224a and the discharge port 224b are provided The left side (with reference to FIG. 4 ) of the rear surface of the pad 224 is inserted and joined. the

The heat insulation pipe 440 is to ensure the cold air flow channel flowing between the cold air pipe 120 and the ice making chamber 400 before filling the heat insulation material in the refrigerator compartment door 20 , and it is inserted into the door lining The concave portion of the pad 224 should have a shape and size corresponding to the concave portion. the

The heat insulation duct 440 is made of the same heat insulation material as the foam E filled between the casing 222 and the door gasket 224, thereby for the ice making chamber 400, especially for the supply port adjacent to The parts of 224a and the discharge port 224b are insulated, thereby preventing the loss of cold air due to heat exchange. the

A supply passage 442 and a discharge passage 444 are formed on the heat insulating duct 440 . The supply path 442 is a perforated structure for communicating the inside and outside of the ice making compartment 400 , so that cold air supplied through the supply duct 122 can flow into the inside of the ice making compartment 400 . the

The discharge passage 444 is provided on the lower side of the supply passage 442, and is the same as the supply passage 442. It is a perforated structure for communicating the inside and outside of the ice making compartment 400, so that the ice making compartment The cold air used for making ice discharged from 400 is discharged through the discharge pipe 124 . the

When installing the heat insulation pipe 440 , the openings of the supply passage 442 and the discharge passage should be aligned with the supply port 224 a and the discharge port 224 b provided on one side of the ice making chamber 400 . the

On the left side of the heat insulation pipe 440 connected to the supply port 224a and the discharge port 224b, a mounting portion 446 for mounting a support bracket 450 to be described below is formed. The placement part 446 is to facilitate the installation and fixing of the support bracket 450 , and its shape is formed to be concave inward corresponding to the shape of the support bracket 450 , and is provided at the openings of the supply passage 442 and the discharge passage 444 part. the

In order to improve tightness, it should be made of elastic material. the

The ice-making sealing gasket 460 is composed of an elastic portion 462 and a joint portion 464 . The elastic part 462 is made of elastic material, so that it is close to the end of the opening of the cold air duct 120 provided on the main body 100, and when the ice-making compartment 400 and the main body 100 are rotated through the rotation of the refrigerator compartment door 220 When one side of them is close to each other, it contacts with the open end of the cold air duct 120 . the

The elastic portion 462 is compressed and closely attached to the outer peripheral surface of the opening end of the cold air duct 120 , so that the space between the cold air duct 120 and the ice making chamber 400 will be completely combined. the

The elastic portion 462 is disposed on the joint portion 464 . The joint part 464 is used for installing the ice making compartment gasket 460, and generally forms a disc-shaped structure, and is preferably made of a plastic material with a certain strength. the

A combination protrusion (not shown) corresponding to the gasket installation opening 452b of the support bracket 450 is formed at the approximate center of the combination portion 464 to allow cold air to pass through. An ice chamber gasket 460 may be installed on the support bracket 450 . the

The sealing performance between the heat insulation duct 440 and the cold air duct 120 is further improved through the installation of the ice making compartment gasket 460 . the
