Refrigerator
Disclosed is a refrigerator, in which the installation and the repair and replacement of a wire harness are easily achieved. In a refrigerator, in which a main body includes an inner casing, an outer casing, and a heat insulating layer provided between the inner and outer casings, and electric and electronic components including sensors and switches are electrically connected to a printed circuit board through a wire harness, an opening is formed through one side of the main body, and a harness block in which the wire harness and a plurality of connection housings for installing the wire harness are intensively disposed is detachably installed in the opening.
1. A refrigerator, having a main body that includes an inner casing, an outer casing, and a heat insulating layer provided between the inner and outer casings, and electric and electronic components including sensors and switches are electrically connected to a printed circuit board through a wire harness, comprising:
an opening formed through one side of the main body, and
a harness block in which the wire harness and a plurality of connection housings for installing the wire harness are disposed that is detachably installed in the opening,
wherein the harness block includes a harness body having a hollow structure inserted into the opening and an edge so that the edge of the harness body is caught by the opening, and a heat insulating material filling the inside of the harness body at a side of the inner casing,
wherein the wire harness is in the heat insulating material.
2. The refrigerator according to claim 1 , wherein the printed circuit board is inserted into the harness block such that the plurality of connection housings are electrically connected to the printed circuit board.
3. The refrigerator according to claim 2 , wherein:
the printed circuit board is provided with first connectors and inserted into the inside of the harness body at the side of the outer casing, and the plurality of connection housings are fixed to the heat insulating material such that one end of each of the plurality of connection housings is buried in the surface of the heat insulating material at the side of the inner casing; and
second connectors corresponding to the first connectors are fixed to the heat insulating material such that one end of each of the second connectors is buried in the surface of the heat insulating material at the side of the outer casing, and the wire harness connecting the second connectors and the plurality of connection housings is buried in the heat insulating material.
4. The refrigerator according to claim 1 , wherein a receiving groove is formed in one end of the opening at the side of the outer casing, a flange is formed on the outer circumference of one end of the harness body corresponding to the receiving groove such that the flange is caught by the receiving groove, and a gasket is installed between the receiving groove and the flange.
5. The refrigerator according to claim 2 , wherein the end of the opening at the side of the outer casing is sealed up with a cover under the condition that the harness block is inserted into the opening.
