Description

本発明は、室内機の内部に設けられた高圧発生器による帯電防止に関する。   The present invention relates to prevention of charging by a high-pressure generator provided inside an indoor unit.

従来から、空気調和機の室内機には、空気清浄のために放出させるイオンを発生させるための高圧発生器が取り付けられており、その高圧発生器に取り付けられた放熱板は、制御基板等が内部に配置されるＣ−ＢＯＸから離され、電気的に絶縁された状態で配置されている（例えば、特許文献１参照）。   Conventionally, an indoor unit of an air conditioner has been provided with a high-pressure generator for generating ions to be released for air cleaning, and a heat sink attached to the high-pressure generator is a control board or the like. It is separated from the C-BOX disposed inside and is disposed in an electrically insulated state (see, for example, Patent Document 1).

図５は、従来の空気調和機内に配置されたＣ−ＢＯＸ２と高圧発生器３の配置図であり、図６はＣ−ＢＯＸ２の要部断面図である。図５、図６に示すように、Ｃ−ＢＯＸ２を覆っている板金４に、高圧発生器３の影響により帯電した電位を、制御基板を介して放電するために、制御基板５上にグランドに接続されている接続端子６を実装し、Ｃ−ＢＯＸ２にビス７で固定すると同時に、板金４と接続するように構成している。   FIG. 5 is a layout view of the C-BOX 2 and the high-pressure generator 3 arranged in a conventional air conditioner, and FIG. 6 is a cross-sectional view of the main part of the C-BOX 2. As shown in FIGS. 5 and 6, in order to discharge the potential charged to the metal plate 4 covering the C-BOX 2 due to the influence of the high voltage generator 3 through the control board, it is grounded on the control board 5. The connected connection terminal 6 is mounted and fixed to the C-BOX 2 with a screw 7, and at the same time, connected to the sheet metal 4.

しかしながら、前記従来の構成では、ビス７で固定する必要があるため、ビス止め時に制御基板５の他の実装部品を損傷させる可能性があるという課題を有していた。   However, in the conventional configuration, since it is necessary to fix with the screw 7, there is a problem that other mounting parts of the control board 5 may be damaged at the time of screwing.

本発明は、前記従来の課題を解決するために、制御基板を配置した場合に制御基板の実装部品の損傷を防止することができる空気調和機を提供することを目的とする。   In order to solve the above-described conventional problems, an object of the present invention is to provide an air conditioner that can prevent damage to components mounted on a control board when the control board is arranged.

前記従来の課題を解決するために本発明の空気調和機は、制御基板を内部に配置するＣ−ＢＯＸと、前記Ｃ−ＢＯＸの外部を覆う板金と、前記板金の外方に設けられ、放熱板が接続された高圧発生器と、を備え、前記板金には接触端子を設け、前記制御基板を前記Ｃ−ＢＯＸに配置したときに、前記接触端子が前記制御基板のグランドパターンに接触するように構成し、前記板金と前記放熱板とを電気的に接続し、前記放熱板に帯電した電位を前記板金と前記接触端子とを介して前記制御基板から放電させることにより、制御基板にビス止めをする必要がないため、制御基板に配置された実装部品の損傷を防止することができる。
In order to solve the conventional problems, an air conditioner according to the present invention is provided with a C-BOX in which a control board is disposed, a sheet metal that covers the outside of the C-BOX, and an outer side of the sheet metal, comprising a high pressure generator plate is connected, and wherein the sheet metal provided with contact terminals, when placing the control board to the C-BOX, to the contact terminal is in contact with the ground pattern of the control board The sheet metal and the heat radiating plate are electrically connected , and the electric potential charged to the heat radiating plate is discharged from the control board via the sheet metal and the contact terminal, thereby screwing the control board. Therefore, it is possible to prevent damage to the mounted components arranged on the control board.

本発明は、制御基板を配置した場合に制御基板の実装部品の損傷を防止することができる空気調和機を提供することができる。   The present invention can provide an air conditioner that can prevent damage to components mounted on a control board when the control board is arranged.

第１の発明の空気調和機は、制御基板を内部に配置するＣ−ＢＯＸと、前記Ｃ−ＢＯＸの外部を覆う板金と、前記板金の外方に設けられ、放熱板が接続された高圧発生器と、を備え、前記板金には接触端子を設け、前記制御基板を前記Ｃ−ＢＯＸに配置したときに、前記接触端子が前記制御基板のグランドパターンに接触するように構成し、前記板金と前記放熱板とを電気的に接続し、前記放熱板に帯電した電位を前記板金と前記接触端子とを介して前記制御基板から放電させることにより、制御基板にビス止めをする必要がないため、制御基板に配置された実装部品の損傷を防止することができる。 An air conditioner according to a first aspect of the present invention is a high-pressure generator in which a C-BOX having a control board disposed therein, a sheet metal that covers the outside of the C-BOX, and a heat sink that is provided outside the sheet metal comprising a vessel, a, wherein the sheet metal provided with contact terminals, when placing the control board to the C-BOX, configured such that the contact terminal is in contact with the ground pattern of the control board, and the sheet metal wherein connecting the heat radiating plate electrically, by discharging the charged potential to the radiator plate from the control board via said contact terminal and the metal plate, it is not necessary to screwing on the control board, It is possible to prevent damage to the mounted components arranged on the control board.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

図１は、本発明の実施の形態１における空気調和機の説明図、図２は、実施の形態１における制御基板と高圧発生器との配置図、図３は、実施の形態１におけるＣ−ＢＯＸ２の要部断面図、図４は、実施の形態１における回路図である。なお、従来の構成と同じ部位については、同じ符号を付して説明する。 (Embodiment 1)
FIG. 1 is an explanatory diagram of an air conditioner according to Embodiment 1 of the present invention, FIG. 2 is a layout diagram of a control board and a high-pressure generator according to Embodiment 1, and FIG. FIG. 4 is a circuit diagram of the first embodiment. In addition, about the same site | part as the conventional structure, the same code | symbol is attached | subjected and demonstrated.

図１から図４に示すように、本発明の空気調和機の室内機１の内部に、Ｃ−ＢＯＸ２（コントロールボックス）が配置されており、Ｃ−ＢＯＸ２の近傍には高圧発生器３が設けられている。さらに、高圧発生器３には放熱板１１が取り付けられている。   As shown in FIGS. 1 to 4, a C-BOX 2 (control box) is arranged inside the indoor unit 1 of the air conditioner of the present invention, and a high-pressure generator 3 is provided in the vicinity of the C-BOX 2. It has been. Further, a heat radiating plate 11 is attached to the high pressure generator 3.

図３に示すように、Ｃ−ＢＯＸ２の周囲は、板金４で覆われており、板金４には接触端子９を設けている。さらに、板金４は放熱板１１とビス１２で固定されている。すなわち、放熱板１１と接触端子９とは電気的に接続されている状態となっている。   As shown in FIG. 3, the periphery of the C-BOX 2 is covered with a sheet metal 4, and a contact terminal 9 is provided on the sheet metal 4. Further, the sheet metal 4 is fixed to the heat radiating plate 11 and screws 12. That is, the heat sink 11 and the contact terminal 9 are in an electrically connected state.

ここで、Ｃ−ＢＯＸ２に制御基板５を配置すると、制御基板５の二次側グランド８のパタンに、接触端子９が接触し接続される。   Here, when the control board 5 is arranged on the C-BOX 2, the contact terminal 9 contacts and is connected to the pattern of the secondary side ground 8 of the control board 5.

図４は、制御基板５内の放電経路の回路図である。本発明の空気調和機のように、高圧発生器３を搭載している空気調和機は、高圧発生器３周辺の温度や湿度などの雰囲気の影響により高圧発生器３の放熱板１１やＣ−ＢＯＸ２を覆っている板金４を帯電させる。   FIG. 4 is a circuit diagram of a discharge path in the control board 5. Like the air conditioner of the present invention, the air conditioner equipped with the high pressure generator 3 is affected by the atmosphere such as temperature and humidity around the high pressure generator 3 and the heat sink 11 and C− of the high pressure generator 3. The sheet metal 4 covering the BOX 2 is charged.

また、スイッチングトランス１０の１次―２次間は、５０ＭΩ以上の抵抗１２で接続されているため、高圧発生器３の放熱板１１に帯電した電位を、板金４から接触端子９を経由して制御基板５の２次側から１次側回路に放電することで、制御基板５の誤動作や破壊を防止することができる。   Since the primary-secondary of the switching transformer 10 is connected by a resistor 12 of 50 MΩ or more, the potential charged on the heat radiation plate 11 of the high-voltage generator 3 is transferred from the sheet metal 4 via the contact terminal 9. By discharging from the secondary side of the control board 5 to the primary side circuit, malfunction and destruction of the control board 5 can be prevented.

以上のように、本発明は、高圧発生器を搭載した空気調和機以外の機器の用途にも適用できる。   As mentioned above, this invention is applicable also to the use of apparatuses other than the air conditioner which mounts a high voltage | pressure generator.
