[21] According to a feature of the control box of the integrated air conditioner according to the present invention for solving the above problems, the control box is installed on one side of the front panel in which the suction grill and the discharge grill is formed to control the operation of the air conditioner And an electrostatic precipitator configured to ionize and remove foreign substances in the air sucked by the suction grill, wherein the control box has a control case having a front surface and an upper surface opened and a capacitor installed therein; A cover installed to open and close on an upper surface of the control case, a display panel coupled to a front surface of the control case, and fixing means formed on the control case and the cover to fix the capacitor when the cover is closed. It is composed.
[22] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[23] As shown in FIG. 3, the integrated air conditioner according to the present invention has a suction port 31a formed at a side of the cabinet 31 mounted on a window or a wall to suck outdoor air, and the outdoor of the cabinet 31. A discharge port (not shown) for discharging air to the outside is formed on the rear surface of the side, and a suction grill 32a for sucking air in the room and a discharge grill 32b for discharging air into the room are provided on the front surface of the cabinet 31. The disposed front panel 32 is assembled.
[24] In addition, a control box 40 for controlling the operation of the air conditioner and confirming an operation state according to the discharge grill 32b is disposed at one side of the discharge grill 32b, and the cabinet is disposed at one side of the front panel 32. A refrigeration cycle apparatus is installed inside 31 to absorb heat of indoor air by using a refrigerant circulating in the refrigeration cycle apparatus, and then radiate it to the outside.
[25] In addition, the cabinet 31 is provided with an indoor and outdoor heat exchanger for cooling operation, a compressor, a fan, and the like, and an electric dust collector for air cleaning.
[26] In this case, the control box 40 will be described in more detail with reference to FIG. 4. The front and top surfaces of the control box 40 are opened, and a plurality of electronic components 41a for controlling the operation of the air conditioner are mounted therein. A control case 43 in which a substrate 41 and a capacitor 42 for securing capacitance are installed, a cover 44 in which an upper surface of the control case 43 is opened and closed, and the control case ( Fixing means (43d) formed on the display panel 45 and the control case 43 and the cover 44 coupled to the front of the 43 so that the capacitor 42 can be fixed when the cover 44 is closed 44b).
[27] In addition, the display panel 45 is provided with a display hole 45b and a pressing part 45c, and a plurality of tet switches 46a are mounted on the rear surface of the display panel 45 behind the pressing part 45c. And a display substrate 46 on which the display component 46b is installed in a portion corresponding to the display hole 45b, and coupled to the front surface of the display panel 45 on the front surface of the display panel 45. The display window 47 indicating the information displayed on the display component 46a is disposed.
[28] In addition, one side of the display panel 45 is located at the rear of the front panel 32, the limit switch 45f for disconnecting the power supplied to the electric dust collector described above when the front panel 32 is removed The switch mounting portion 45e to be mounted is formed, so that the electrostatic precipitator can be prevented from operating when the front panel 32 is removed.
[29] Meanwhile, a plurality of fitting grooves 44a are formed at one side of the cover 44, and one side end of an upper surface of the control case 43 corresponding to the cover 44 is fitted to the plurality of fitting grooves 44a. A plurality of fitting protrusions 43a are formed to allow the upper surface of the control case 43 and the cover 44 to be coupled to each other.
[30] In addition, the groove 45a formed at one end of the display panel 45 is fitted into the protrusion 43b formed at one end of the front surface of the control case 43, and is formed at the other end of the display panel 45. The protrusions (not shown) formed are inserted into a plurality of grooves 43c formed at the other end of the front side of the control case 43 so that the display panel 45 is coupled to the front side of the control case 43.
[31] On the other hand, the display window 47 is a front surface of the display panel 45 so that the projection (47a) fitted in the hole (45d) formed in the front of the display panel 45 protrudes to block the display hole (45b). Is coupled to.
[32] In addition, the fixing means 43d and 44b may include a first fixing part 43d formed on one inner surface of the control case 43 so as to surround the lower part of the capacitor 42 when the capacitor 42 is installed. When the cover 44 is closed, it consists of a second fixing portion 44b which is formed in the lower surface direction of the cover 42 to surround the upper portion of the capacitor 42, the first and second fixing portion 43d , 44b) may have various shapes depending on the shape of the capacitor 42 without having a predetermined shape.
[33] In other words, when the capacitor 42 is formed in a cylindrical shape, as shown in FIG. 5, the first fixing part 43d and the second fixing part 44b are also cylindrical in the same manner as the capacitor 42. The first fixing portion 43d surrounds the lower portion of the capacitor 42, and the second fixing portion 44b surrounds the upper portion of the capacitor 42, so that the capacitor 42 It can be fixed.
[34] Therefore, since the control box 20 does not need a clamp and a bolt for fixing the clamp in order to fix the capacitor, the number of parts in the assembly process is reduced, as well as the cost is reduced, and the process is simplified to assemble. To improve.
[35] The control box of the integrated air conditioner according to the present invention configured as described above comprises a control case, a cover for opening and closing the upper surface of the control case and a display panel coupled to the front of the control case is the operation of the air conditioner In the case of installing a capacitor for securing the capacitance in the control box to control the control and check the operation state accordingly, the first fixing part and the second fixing part formed on the control case and the cover respectively, the lower and upper portions of the capacitor By wrapping, since there is no need for a separate fixing means, the number of assembly parts can be reduced, thereby simplifying the assembly process and improving workability.
[36] In addition, by forming a switch mounting portion that is equipped with a limit switch to cut off the power supplied to the electrostatic precipitator when the front panel is removed on one side of the display panel, it is possible to prevent the electrostatic precipitator from operating when the front panel is removed It works.
