Abstract

PROBLEM TO BE SOLVED: To solve a problem in an air conditioner wherein if a heat radiation plate is attached to a high voltage generator, the heat radiation plate is charged with electricity due to influence of an ambient temperature or the like, and a control board in a control box causes malfunction when there is discharge to a conductive part of a high voltage generator interior.SOLUTION: In the air conditioner, by connecting the heat radiation plate 6 of the high voltage generator 3 to sheet metal 4 of the control box 2, and directly connecting the sheet metal 4 to a secondary side ground 9 of the control board 7, an electric potential charged in the heat radiation plate 6 of the high voltage generator and the sheet metal 4 of the control box can be discharged to the secondary side ground 9 of the control board, and charging of the heat radiation plate 6 can be prevented.

Description

本発明は、高圧発生器の放熱板と制御基板を収納するコントロールボックスに取り付けられた板金とを接続し、さらにコントロールボックスの板金を制御基板の２次側グランドに接続することにより高圧発生器による帯電を防止することができる空気調和機に関するものである。   The present invention relates to a high voltage generator by connecting a heat radiation plate of a high voltage generator and a metal plate attached to a control box containing a control board, and further connecting the metal plate of the control box to a secondary side ground of the control board. The present invention relates to an air conditioner capable of preventing charging.

従来、イオンを発生させる高圧発生器に取り付けられた放熱板は、コントロールボックスから離れており電気的に絶縁された状態で空気調和機に搭載されている（例えば、特許文献１参照）。   Conventionally, a heat sink attached to a high-pressure generator that generates ions is mounted on an air conditioner in a state of being electrically insulated from a control box (see, for example, Patent Document 1).

図５〜図７に、特許文献１に記載された従来の空気調和機１とコントロールボックス２と高圧発生器３の構成図を示す。コントロールボックス２を覆っている板金４においては、高圧発生器３の影響により帯電した電位をアース線５を通じて放電している。   5 to 7 are configuration diagrams of the conventional air conditioner 1, the control box 2, and the high pressure generator 3 described in Patent Document 1. FIG. In the sheet metal 4 covering the control box 2, the charged potential due to the influence of the high voltage generator 3 is discharged through the ground wire 5.

しかしながら、前記従来の構成では、高圧発生器３の放熱板６は、高圧発生器３に近くにあるため絶縁状態であっても湿度などの影響により放熱板６は帯電し、高圧発生器３内部の導電部に放電して、制御基板７と接続しているリード線８経由することでコントロールボックス２内の制御基板７が誤動作するという課題を有していた。   However, in the conventional configuration, the heat radiating plate 6 of the high voltage generator 3 is close to the high voltage generator 3, so that the heat radiating plate 6 is charged due to the influence of humidity or the like even in an insulated state, There is a problem that the control board 7 in the control box 2 malfunctions by discharging to the conductive portion and passing through the lead wire 8 connected to the control board 7.

本発明は、前記従来の課題を解決するもので、高圧発生器３の放熱板６をコントロールボックス２の板金４に接続し、前記板金４をコントロールボックス２内の制御基板７の２次側グランド９に接続することで高圧発生器３により放熱板６が帯電を発生させない空気調和機を提供することを目的とする。   The present invention solves the above-described conventional problem, and connects the heat sink 6 of the high voltage generator 3 to the sheet metal 4 of the control box 2, and the sheet metal 4 is connected to the secondary side ground of the control board 7 in the control box 2. It is an object of the present invention to provide an air conditioner in which the high-pressure generator 3 prevents the radiator plate 6 from being charged by being connected to 9.

前記従来の課題を解決するために、本発明の空気調和機１は、高圧発生器３の放熱板６とコントロールボックス２の板金４とスイッチングトランス１０で絶縁された２次側グランド９を接続する。   In order to solve the above-described conventional problems, the air conditioner 1 of the present invention connects the heat sink 6 of the high pressure generator 3, the sheet metal 4 of the control box 2, and the secondary ground 9 insulated by the switching transformer 10. .

これによって、高圧発生器の影響により放熱板に帯電した電位は、高圧発生器の導電部へ放電することなく、制御基板の誤動作を防止することができる。   As a result, the potential charged on the heat sink due to the influence of the high voltage generator can be prevented from malfunctioning the control board without discharging to the conductive portion of the high voltage generator.

本発明の空気調和機は、高圧発生器の放熱板とコントロールボックスの板金に帯電した電位を制御基板の２次側グランドに放電することができる。   The air conditioner of the present invention can discharge the electric potential charged to the heat sink of the high pressure generator and the sheet metal of the control box to the secondary side ground of the control board.

本発明は、高圧発生器の放熱板とコントロールボックスの板金を接続し、前記板金を制御基板の２次側グランドのパターンにビスにより固定かつ接続するものである。   In the present invention, the heat sink of the high-voltage generator and the sheet metal of the control box are connected, and the sheet metal is fixed and connected to the secondary ground pattern of the control board with screws.

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.

（実施の形態１）
図１は、本発明の第１の実施の形態における空気調和機１とコントロールボックス２と高圧発生器３と高圧発生器３の放熱板６における構成図である。図２は、コントロールボックス２と高圧発生器３との構成図である。図３はコントロールボックス２の板金４と制御基板７とを接続端子１２にてビス１１により接続させた構成図である。図４は、制御基板内７の放電経路の回路図である。 (Embodiment 1)
FIG. 1 is a configuration diagram of the air conditioner 1, the control box 2, the high pressure generator 3, and the heat dissipation plate 6 of the high pressure generator 3 according to the first embodiment of the present invention. FIG. 2 is a configuration diagram of the control box 2 and the high-pressure generator 3. FIG. 3 is a configuration diagram in which the sheet metal 4 of the control box 2 and the control board 7 are connected to each other by screws 11 at the connection terminals 12. FIG. 4 is a circuit diagram of a discharge path in the control board 7.

高圧発生器３を搭載している空気調和機１は、高圧発生器３周辺の雰囲気の影響により高圧発生器３の放熱板６やコントロールボックス２を覆っている板金４を帯電させる。高圧発生器３の放熱板６は、コントロールボックス２の板金４とビス止めされ接続されている。また、コントロールボックス２の板金６は、コントロールボックス２内の制御基板７に接続端子１２とビス１１で固定され接続されており、接続端子１１は、２次側グランド９のパターンに直接接続されている。スイッチングトランス９の１次―２次間は、５０ＭΩ以上の１−２次間抵抗１３で接続されているため、高圧発生器３の放熱板６に帯電した電位を板金４を経由して制御基板７の１次側回路に放電することで、制御基板の誤動作や破壊を防止することができる。   The air conditioner 1 equipped with the high pressure generator 3 charges the sheet metal 4 covering the heat radiating plate 6 and the control box 2 of the high pressure generator 3 due to the influence of the atmosphere around the high pressure generator 3. The heat radiating plate 6 of the high pressure generator 3 is screwed and connected to the metal plate 4 of the control box 2. Further, the sheet metal 6 of the control box 2 is fixedly connected to the control board 7 in the control box 2 with a connection terminal 12 and a screw 11, and the connection terminal 11 is directly connected to the pattern of the secondary side ground 9. Yes. Since the primary-secondary of the switching transformer 9 is connected by a primary-secondary resistor 13 of 50 MΩ or more, the potential charged on the heat radiating plate 6 of the high-voltage generator 3 is supplied to the control board via the sheet metal 4. 7 can be prevented from malfunctioning or being destroyed.

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.
