a clothes care compartment provided inside the body to receive clothes; a machine room provided inside the body and separated from the clothes care compartment; a printed circuit board housing forming one side wall of the machine room, forming a partition to separate a receiving space from the machine room, and ventilating the receiving space by circulating a flow of ambient air from outside the body; and a printed circuit board assembly arranged in the receiving space to be cooled by the ambient air circulating through the receiving space from the outside of the body. ### Claim 2 (depends on 1) The clothes care apparatus of claim 1, wherein the printed circuit board housing comprises: a first housing forming one side wall of the machine room; and a second housing forming the receiving space by being coupled to the first housing, and partitioning the receiving space from the machine room. ### Claim 3 (depends on 2) The clothes care apparatus of claim 2, wherein the first housing comprises: a first air inlet that allows air outside the body to flow into the receiving space; and a second air inlet that allows air outside the body to flow into the machine room. ### Claim 4 (depends on 2) The clothes care apparatus of claim 2, wherein: the printed circuit board assembly comprises a printed circuit board comprising a mounting surface; and the printed circuit board is arranged such that the mounting surface faces the first housing. ### Claim 5 (depends on 2) The clothes care apparatus of claim 2, wherein, by separating the receiving space from the machine room, the second housing prevents heat of the machine room from being transmitted to the receiving space. ### Claim 6 (depends on 2) The clothes care apparatus of claim 2, further comprising a first cover member arranged between the printed circuit board assembly and the first housing to cover one surface of the printed circuit board assembly, wherein the first cover member is formed of an insulating material to prevent a current from flowing from the printed circuit board assembly to the first housing. ### Claim 7 (depends on 6) The clothes care apparatus of claim 6, wherein the first cover member comprises a plurality of holes configured to allow air to smoothly flow into the printed circuit board assembly in the receiving space. ### Claim 8 (depends on 6) The clothes care apparatus of claim 6, further comprising a second cover member arranged between the printed circuit board assembly and the second housing to cover a second surface opposite to the one surface of the printed circuit board assembly, wherein the second cover member is formed of an insulating material to prevent a current from flowing from the printed circuit board assembly to the second housing. ### Claim 9 (depends on 3) The clothes care apparatus of claim 3, wherein the first housing further comprises an air outlet arranged above the first air inlet and that allows air of the receiving space to be discharged to the outside of the body. ### Claim 10 (depends on 2) The clothes care apparatus of claim 2, further comprising a sealing member arranged between the first housing and the second housing to prevent moisture from flowing to the receiving space. ### Claim 11 (depends on 3) The clothes care apparatus of claim 3, further comprising a fan arranged in the receiving space to suction air outside the body into the receiving space through the first air inlet. ### Claim 12 (depends on 1) The clothes care apparatus of claim 1, wherein the machine room includes a compressor or a steam generator. ### Claim 13 (depends on 12) The clothes care apparatus of claim 12, wherein the printed circuit board assembly comprises an inverter circuit that changes a driving speed of the compressor by a frequency conversion. ### Claim 14 (depends on 2) The clothes care apparatus of claim 2, wherein the second housing is formed of an insulating material to prevent a current from flowing from the printed circuit board assembly to the second housing. ### Claim 15 (depends on 2) The clothes care apparatus of claim 2, wherein, when the first housing is separated from the body, the printed circuit board assembly and a first cover member are exposed to a rear side of the body to allow access from the rear side of the body. ### Claim 16 A clothes care apparatus comprising: a body; a clothes care compartment provided inside the body; a machine room provided inside the body under the clothes care compartment; a printed circuit board housing arranged in the machine room to form a partition to separate a receiving space from the machine room, the printed circuit board housing provided with a first air inlet that flows air outside the body into the receiving space and a second air inlet that flows air outside the body into the machine room; and a printed circuit board assembly arranged in the receiving space. ### Claim 17 (depends on 16) The clothes care apparatus of claim 16, wherein the printed circuit board housing comprises: a first housing forming a rear wall of the machine room, and a second housing forming the receiving space by being coupled to the first housing, and insulating the receiving space from the machine room. ### Claim 18 (depends on 16) The clothes care apparatus of claim 16, wherein: the first air inlet comprises a plurality of first air inlets; the second air inlet comprises a plurality of second air inlets; and a number of the plurality of first air inlets is greater than a number of the plurality of second air inlets. ### Claim 19 (depends on 17) The clothes care apparatus of claim 17, wherein the printed circuit board assembly is arranged to face the first housing such that when the first housing is separated from the body, the printed circuit board assembly is exposed to a rear side of the body. ### Claim 20 A clothes care apparatus comprising: an outer cabinet; a clothes care compartment provided with an open front surface to receive clothes; an inner cabinet arranged inside the outer cabinet and comprising the clothes care compartment; a machine room formed between the outer cabinet and the inner cabinet and provided with an open rear surface; a first housing covering the open rear surface of the machine room to form a rear wall of the machine room; a second housing coupled to the first housing to form a receiving space separated from the machine room; and a printed circuit board assembly arranged in the receiving space to face the first housing.
