a sliding panel having one side on which a first circuit unit is mounted, the sliding panel being accommodated in the accommodation portion so as to be taken out of the control box and a groove is formed in at least one of the top and bottom surfaces of the sliding panel; and a rotation panel having one side on which a second circuit unit is mounted and being rotatably mounted at one side of the control box, and wherein the sliding panel slides along a guide rail that is inserted into the groove by passing through the slit. ### Claim 2 (depends on 1) The air conditioner according to claim 1, wherein one side of the accommodation portion is formed in a forward/backward direction so that the sliding panel is mounted to be taken out of a front of the control box. ### Claim 3 (depends on 2) The air conditioner according to claim 2, wherein the other side of the accommodation portion is formed in right and left directions, and the rotation panel is disposed so that one side of the rotation panel on which the circuit unit is mounted directs forward. ### Claim 4 (depends on 1) The air conditioner according to claim 1, wherein the sliding panel slides in the forward/backward direction along the guide rail. ### Claim 5 (depends on 4) The air conditioner according to claim 4, wherein the guide rail comprises a fixing part and a rail part that is bent from the fixing part. ### Claim 6 (depends on 5) The air conditioner according to claim 5, wherein the rail part passes through the slit and protrudes from an inner side of the control box. ### Claim 7 (depends on 6) The air conditioner according to claim 6, wherein the groove is formed in a movement direction of the sliding panel. ### Claim 8 (depends on 5) The air conditioner according to claim 5, wherein the fixing part is coupled to the control box and fixes the guide rail. ### Claim 9 (depends on 1) The air conditioner according to claim 1, wherein a hinge bracket is coupled to the rotation panel, and the hinge bracket is rotatably mounted on the control box. ### Claim 10 (depends on 9) The air conditioner according to claim 9, wherein the hinge bracket comprises a bracket body and a coupling portion that extends from the bracket body and is mounted on the rotation panel. ### Claim 11 (depends on 10) The air conditioner according to claim 10, wherein the coupling portion comprises a connector that extends from the bracket body and a bent portion that is bent and extends from the connector, and the bent portion is coupled to the rotation panel. ### Claim 12 (depends on 11) The air conditioner according to claim 11, wherein a slit is formed in one side of the control box, the bent portion passes through the slit and protrudes from an inner side of the control box, and the bent portion and sides of the rotation panel are coupled to each other. ### Claim 13 (depends on 10) The air conditioner according to claim 10, wherein the hinge bracket further comprises a rotation limiting portion that extends from the bracket body. ### Claim 14 (depends on 13) The air conditioner according to claim 13, wherein a hole through which the rotation limiting portion passes is formed in one side of the control box. ### Claim 15 (depends on 14) The air conditioner according to claim 14, wherein, when the rotation panel rotates, the rotation limiting portion is positioned at an outer side of the control box, and an external force applied to the rotation panel is removed, the rotation panel descends and the rotation limiting portion is interfered by sidewalls of the control box and limits rotation of the rotation panel and returning to an original position of the rotation panel. ### Claim 16 An air conditioner comprising: a control box in which a first circuit unit and a second circuit unit to perform control related to air conditioning or heating are accommodated; a sliding panel that is disposed in the control box, slides, and is mounted to be taken out of the control box; and a rotation panel that is rotatably mounted at one side of the control box by a hinge bracket, wherein the first circuit unit is mounted at one side of the sliding panel and the second circuit unit is mounted at one side of the rotation panel, the sliding panel is disposed to be taken out of the control box so as to secure a working space for repair or inspection of the first circuit unit and the second circuit unit mounted at one side of the rotation panel is disposed to direct forward, and a slit through which the hinge bracket is formed in one side of the control box, portions of the hinge bracket pass through the slit and are coupled to the rotation panel, and other portions of the hinge bracket are positioned at an outer side of the control box. ### Claim 17 (depends on 16) The air conditioner according to claim 16, wherein a rotation limiting portion that limits rotation of the rotation panel protrudes from the hinge bracket. ### Claim 18 (depends on 17) The air conditioner according to claim 17, wherein a hole through which the rotation limiting portion passes is formed in one side of the control box. ### Claim 19 (depends on 18) The air conditioner according to claim 18, wherein, when an external force is applied to the rotation panel and the rotation panel is rotated so that the rotation limiting portion passes through the hole and the external force applied to the rotation panel is removed, the rotation panel descends and the rotation limiting portion is interfered by sidewalls of the control box and limits rotation of the rotation panel. ### Claim 20 (depends on 16) The air conditioner according to claim 16, wherein repair or inspection of the first circuit unit mounted on the sliding panel or the second circuit unit mounted on the rotation panel is performed in a state in which a cable connected to the first circuit unit and/or the second circuit unit is not separated from the first circuit unit and/or the second circuit unit. ### Claim 21 A control box assembly for a heater or an air conditioner in which components to control the heater or the air conditioner are provided, the control box assembly comprising: a control box; a sliding panel which slides in and out of the control box and a first circuit unit is mounted on one side thereof; a rotating panel which is rotated in and out of the control box and a second circuit unit is mounted on one side thereof; and at least one guide rail along which the sliding panel slides, and wherein the control box includes at least one slit into which an insertion portion of the corresponding at least one guide rail is inserted and the sliding panel includes at least one groove provided in a position corresponding to the insertion portion and formed in a movement direction of the sliding panel. ### Claim 22 (depends on 21) The control box assembly of claim 21, further comprising a hinge bracket which is coupled to the rotation panel and rotatably mounted on the control box. ### Claim 23 (depends on 22) The control box assembly of claim 22, wherein the control box includes at least one slit into which a portion of the hinge bracket is inserted and is formed in a portion of the control box, the portion of the hinge bracket inserted into the slit and are coupled to the rotation panel, and the other portion of the hinge bracket are positioned at an outer side of the control box. ### Claim 24 (depends on 23) The control box assembly of claim 23, wherein the hinge bracket includes a rotation limiting portion that limits rotation of the rotation panel protrudes from the hinge bracket and a hole through which the rotation limiting portion is inserted and is formed in one side of the control box.
