ところで、上述のように、ＨＡシステムに接続させるＨＡ通信回路は絶縁が必要な負荷回路である。元々、ＨＡ通信回路自体は部品点数が少ないため、従来のように電源装置が絶縁回路の場合には、そのままＨＡ通信回路を組み込んでも電源装置全体の部品点数の増加は少なかった。 By the way, as described above, the HA communication circuit connected to the HA system is a load circuit that requires insulation. Originally, since the HA communication circuit itself has a small number of parts, when the power supply device is an insulated circuit as in the conventional case, the increase in the number of parts of the entire power supply device is small even if the HA communication circuit is incorporated as it is.

しかしながら、電源装置が、一次側と二次側とを非絶縁状態として、一次側から二次側へと電力供給を可能とした非絶縁回路の場合、ＨＡ通信回路を絶縁させるためには、フォトカプラや抵抗を実装した回路を別途設ける必要がある。このため、電源装置の部品点数が増加するという問題が生じる。 However, in the case of a non-insulated circuit in which the primary side and the secondary side are in a non-insulated state and power can be supplied from the primary side to the secondary side, in order to insulate the HA communication circuit, a photo It is necessary to separately provide a circuit on which a coupler and a resistor are mounted. Therefore, there arises a problem that the number of parts of the power supply device increases.

本発明の一態様は、非絶縁回路である電源装置に対して、絶縁が必要な負荷回路を追加する際の部品点数の増加を抑制できる電源装置を実現することを目的とする。 One aspect of the present invention is to realize a power supply device that can suppress an increase in the number of parts when a load circuit that requires insulation is added to a power supply device that is a non-isolated circuit.

上記の課題を解決するために、本発明の一態様に係る電源装置は、一次側と二次側が非絶縁状態であるトランスを備えた電源回路と、絶縁が必要な負荷を搭載した絶縁回路を、上記電源回路に電気的に接続するためのアダプタと、が設けられていることを特徴としている。 In order to solve the above problems, the power supply device according to one aspect of the present invention includes a power supply circuit having a transformer in which the primary side and the secondary side are in a non-insulated state, and an insulated circuit equipped with a load requiring insulation. It is characterized in that an adapter for electrically connecting to the power supply circuit is provided.

本発明の一態様によれば、非絶縁回路である電源装置に対して、絶縁が必要な負荷回路を追加する際の部品点数の増加を抑制できる。 According to one aspect of the present invention, it is possible to suppress an increase in the number of parts when adding a load circuit that requires insulation to a power supply device that is a non-insulated circuit.

〔実施形態１〕
以下、本発明の一実施形態について、詳細に説明する。なお、本実施形態では、本発明の電源装置をエアコンの室内機に搭載された例について説明する。 [Embodiment 1]
Hereinafter, one embodiment of the present invention will be described in detail. In this embodiment, an example in which the power supply device of the present invention is mounted on an indoor unit of an air conditioner will be described.

（電源装置１０１）
図１は、本実施形態に係る電源装置１０１の回路図である。 (Power supply device 101)
FIG. 1 is a circuit diagram of the power supply device 101 according to the present embodiment.

電源装置１０１は、図１に示すように、ＳＷ（スイッチング）トランスの一次側と二次側とで、接地電位（０Ｖ）が共通化されている。換言すれば、電源装置１０１は、ＳＷトランスの一次側の平滑用コンデンサのＧＮＤ（０Ｖ）と二次側のマイコンのＧＮＤ（０Ｖ）とを電気的に接続して、非絶縁回路としている。 As shown in FIG. 1, the power supply device 101 has a common ground potential (0V) on the primary side and the secondary side of the SW (switching) transformer. In other words, the power supply device 101 electrically connects the GND (0V) of the smoothing capacitor on the primary side of the SW transformer and the GND (0V) of the microcomputer on the secondary side to form a non-insulated circuit.

電源装置１０１のＳＷトンラスの二次側において、ＰＣＩ（プラズマクラスターイオン）発生回路１１は、非絶縁回路と絶縁されている。換言すれば、ＰＣＩ（プラズマクラスターイオン）発生回路１１は、電源１２Ｖ（Ａ）とは別の絶縁された巻き線によりプラズマクラスター駆動用電源１２Ｖ（Ｂ）を作り、１個のフォトカプラを用いることで、電源１２Ｖ（Ａ）側の回路と絶縁されている。 The PCI (plasmacluster ion) generation circuit 11 is insulated from the non-insulated circuit on the secondary side of the SW tonlas of the power supply device 101. In other words, the PCI (plasmacluster ion) generation circuit 11 creates a plasmacluster drive power supply 12V (B) with an insulated winding different from the power supply 12V (A), and uses one photocoupler. It is insulated from the circuit on the power supply 12V (A) side.

電源装置１０１は、一次側の電源と、二次側のマイコンからの信号線に接続された通信端子１０を備えている。通信端子１０は、ホームオートメンションシステム（以下、ＨＡシステムと称する）に接続するためのＨＡ通信回路１０２（後述）を接続するための端子である。 The power supply device 101 includes a power supply on the primary side and a communication terminal 10 connected to a signal line from the microcomputer on the secondary side. The communication terminal 10 is a terminal for connecting an HA communication circuit 102 (described later) for connecting to a home automation system (hereinafter referred to as an HA system).

（システム全体）
図２は、エアコン１がＨＡシステム２に接続されたシステム構成を示す図である。 (Whole system)
FIG. 2 is a diagram showing a system configuration in which the air conditioner 1 is connected to the HA system 2.

エアコン１は、電源装置１０１に接続されたＨＡ通信回路１０２を介してＨＡシステム２に接続されている。なお、ＨＡシステム２には、複数のエアコン１が接続されている。 The air conditioner 1 is connected to the HA system 2 via the HA communication circuit 102 connected to the power supply device 101. A plurality of air conditioners 1 are connected to the HA system 2.

ＨＡ通信回路１０２は、電源装置１０１の通信端子１０に接続されると共に、ＨＡシステム２の端子３０にも接続されている。具体的には、ＨＡ通信回路１０２の端子２０ａに、電源装置１０１の通信端子１０が接続され、ＨＡ通信回路１０２の端子２０ｂに、ＨＡシステム２の端子３０が接続されている。 The HA communication circuit 102 is connected to the communication terminal 10 of the power supply device 101 and also to the terminal 30 of the HA system 2. Specifically, the communication terminal 10 of the power supply device 101 is connected to the terminal 20a of the HA communication circuit 102, and the terminal 30 of the HA system 2 is connected to the terminal 20b of the HA communication circuit 102.

電源装置１０１とＨＡ通信回路１０２との接続線として、非絶縁の５Ｖ電源（ＶＣＣ５）に接続された線、絶縁した５Ｖ電源（ＶＣＣ５）に接続された線、絶縁した回路のＧＮＤに接続された線、ＨＡシステム２への入出力信号を送信するための線（ＨＡ_ＩＮ、ＨＡ_ＯＵＴ）が必要であり、通信端子１０には、これらの線が接続されている。 As the connection line between the power supply device 101 and the HA communication circuit 102, it was connected to a line connected to a non-insulated 5V power supply (VCC5), a line connected to an insulated 5V power supply (VCC5), and a GND of an insulated circuit. Lines, lines (HA_IN, HA_OUT) for transmitting input / output signals to the HA system 2 are required, and these lines are connected to the communication terminal 10.

従って、ＨＡ通信回路１０２は、電源装置１０１の通信端子１０からの各種信号を、端子２０ａを介して受信し、ＨＡシステム２に端子２０ｂから送信する一方、ＨＡシステム２からの信号を端子２０ｂで受信して、端子２０ａから電源装置１０１に送信している。 Therefore, the HA communication circuit 102 receives various signals from the communication terminal 10 of the power supply device 101 via the terminal 20a and transmits the signals from the HA system 2 to the HA system 2 from the terminal 20b, while transmitting the signals from the HA system 2 at the terminal 20b. It is received and transmitted from the terminal 20a to the power supply device 101.

（ＨＡ通信回路１０２の設置）
図３は、電源装置１０１のメイン基板１０１ａの平面図である。図４は、ＨＡ通信回路１０２の平面図である。図５は、メイン基板１０１ａにＨＡ通信回路１０２を搭載した例を示し、（ａ）は平面図、（ｂ）は（ａ）のＸＸ線矢視断面図である。 (Installation of HA communication circuit 102)
FIG. 3 is a plan view of the main board 101a of the power supply device 101. FIG. 4 is a plan view of the HA communication circuit 102. 5A and 5B show an example in which the HA communication circuit 102 is mounted on the main board 101a, where FIG. 5A is a plan view and FIG. 5B is a cross-sectional view taken along the line XX of FIG. 5A.

メイン基板１０１ａには、ＨＡ通信回路１０２を電気的に接続するためのアダプタとしてのソケット１０３が形成されている。すなわち、電源装置１０１は、一次側と二次側が非絶縁状態であるＳＷトランスを備えたメイン基板（電源回路）１０１ａと、絶縁が必要な負荷を搭載した絶縁回路であるＨＡ通信回路１０２と、ＨＡ通信回路１０２をメイン基板１０１ａに電気的に接続するためのソケット１０３とを備えている。 A socket 103 as an adapter for electrically connecting the HA communication circuit 102 is formed on the main board 101a. That is, the power supply device 101 includes a main board (power supply circuit) 101a having a SW transformer in which the primary side and the secondary side are in a non-insulated state, an HA communication circuit 102 which is an insulating circuit equipped with a load requiring insulation, and the like. A socket 103 for electrically connecting the HA communication circuit 102 to the main board 101a is provided.

ソケット１０３は、上述した電源装置１０１の通信端子１０に接続されている。図５の（ａ）（ｂ）に示すように、ＨＡ通信回路１０２をメイン基板１０１ａに搭載する際に、当該ＨＡ通信回路１０２の裏面１０２ｂに形成された端子２０ａ（図２）のそれぞれの信号線に接続されたピン（図示せず）がソケット１０３に挿入される。これにより、電源装置１０１にＨＡ通信回路１０２が電気的に接続される。 The socket 103 is connected to the communication terminal 10 of the power supply device 101 described above. As shown in FIGS. 5A and 5B, when the HA communication circuit 102 is mounted on the main board 101a, each signal of the terminals 20a (FIG. 2) formed on the back surface 102b of the HA communication circuit 102 A pin (not shown) connected to the wire is inserted into the socket 103. As a result, the HA communication circuit 102 is electrically connected to the power supply device 101.

ＨＡ通信回路１０２は、図４に示すように、表面１０２ａが絶縁状態に加工されている。従って、ＨＡ通信回路１０２を電源装置１０１のソケット１０３に接続した状態であれば、人が当該ＨＡ通信回路１０２の表面１０２ａに触れても問題無いようになっている。 As shown in FIG. 4, the surface 102a of the HA communication circuit 102 is processed to be in an insulated state. Therefore, as long as the HA communication circuit 102 is connected to the socket 103 of the power supply device 101, there is no problem even if a person touches the surface 102a of the HA communication circuit 102.

また、メイン基板１０１ａに、ＨＡ通信回路１０２を、ソケット１０３を用いて接続したときに、当該ＨＡ通信回路１０２を固定する固定部材として棒状の固定用スペーサ１０４が設けられている。つまり、ＨＡ通信回路１０２は、電源装置１０１のソケット１０３に接続した状態で、さらに、電源装置１０１のメイン基板１０１ａ上のソケット１０３近傍に形成された棒状の固定用スペーサ１０４によって固定される。具体的には、ＨＡ通信回路１０２がソケット１０３に接続された状態で、当該ＨＡ通信回路１０２の裏面１０２ｂから表面１０２ａに向かって固定用スペーサ１０４が貫通する位置に孔を形成する。これにより、ＨＡ通信回路１０２をソケット１０３に接続する際に、当該孔から固定用スペーサ１０４を貫通させることで、ＨＡ通信回路１０２をメイン基板１０１ａの所定の位置に確実に固定することが可能となる。 Further, when the HA communication circuit 102 is connected to the main board 101a by using the socket 103, a rod-shaped fixing spacer 104 is provided as a fixing member for fixing the HA communication circuit 102. That is, the HA communication circuit 102 is fixed to the socket 103 of the power supply device 101 by a rod-shaped fixing spacer 104 formed in the vicinity of the socket 103 on the main board 101a of the power supply device 101. Specifically, in a state where the HA communication circuit 102 is connected to the socket 103, a hole is formed at a position where the fixing spacer 104 penetrates from the back surface 102b to the front surface 102a of the HA communication circuit 102. As a result, when the HA communication circuit 102 is connected to the socket 103, the HA communication circuit 102 can be reliably fixed at a predetermined position on the main board 101a by passing the fixing spacer 104 through the hole. Become.

（効果）
図１に示す電源装置１０１による効果について、図６に示す電源装置２０１を参照しながら以下に説明する。 (effect)
The effect of the power supply device 101 shown in FIG. 1 will be described below with reference to the power supply device 201 shown in FIG.

図６に示す電源装置２０１では、ＳＷトランスの一次側と二次側とで絶縁された絶縁回路を構成しているため、当然、ＨＡ通信回路１０２に接続するための通信端子１０も絶縁されている。通信端子１０に接続される二次側からの信号線にフォトカプラを設けて、当該通信端子１０と二次側とを絶縁状態にしている。 In the power supply device 201 shown in FIG. 6, since an insulated circuit is configured on the primary side and the secondary side of the SW transformer, naturally, the communication terminal 10 for connecting to the HA communication circuit 102 is also insulated. There is. A photocoupler is provided on the signal line from the secondary side connected to the communication terminal 10 to insulate the communication terminal 10 from the secondary side.

一方、図１に示す電源装置１０１では、ＳＷトランスの一次側の平滑用コンデンサのＧＮＤ（０Ｖ）と二次側のマイコンのＧＮＤ（０Ｖ）とを電気的に接続して、非絶縁回路を構成しているため、通信端子１０には二次側からの信号線が直接接続されている。つまり、通信端子１０と二次側とが非絶縁状態であるため、図６に示すように、通信端子１０に接続される二次側からの信号線に絶縁用のフォトカプラを設ける必要はない。 On the other hand, in the power supply device 101 shown in FIG. 1, a non-insulated circuit is configured by electrically connecting the GND (0V) of the smoothing capacitor on the primary side of the SW transformer and the GND (0V) of the microcomputer on the secondary side. Therefore, the signal line from the secondary side is directly connected to the communication terminal 10. That is, since the communication terminal 10 and the secondary side are in a non-insulated state, it is not necessary to provide an insulating photocoupler in the signal line from the secondary side connected to the communication terminal 10 as shown in FIG. ..

従って、図１に示す非絶縁回路構成の電源装置１０１は、図６に示す絶縁回路構成の電源装置２０１よりも、通信端子１０を絶縁するためのフォトカプラ等の部品数分だけ、全体の構成部品の数が少なくて済む。 Therefore, the power supply device 101 having a non-insulated circuit configuration shown in FIG. 1 has an overall configuration as compared to the power supply device 201 having an insulated circuit configuration shown in FIG. 6 by the number of parts such as a photocoupler for insulating the communication terminal 10. The number of parts is small.

しかも、通信端子１０に絶縁回路構成のＨＡ通信回路１０２を電気的に接続することで、メイン基板である電源装置１０１は非絶縁回路構成であっても、人が触れそうな部分（通信端子１０）を当該ＨＡ通信回路１０２によって絶縁することができる。つまり、メイン基板が非絶縁回路構成であっても、安全対策を容易に行うことができるという効果がある。 Moreover, by electrically connecting the HA communication circuit 102 having an insulated circuit configuration to the communication terminal 10, even if the power supply device 101 which is the main board has a non-insulated circuit configuration, a portion that is likely to be touched by a person (communication terminal 10). ) Can be insulated by the HA communication circuit 102. That is, even if the main board has a non-insulated circuit configuration, there is an effect that safety measures can be easily taken.

また、ＨＡ通信回路１０２は、電源装置１０１に対して必要に応じて接続することができる別基板で構成できるため、ＨＡシステムが必要なユーザのみ、ＨＡ通信回路１０２を電源装置１０１に接続すればよいことになる。 Further, since the HA communication circuit 102 can be configured with a separate board that can be connected to the power supply device 101 as needed, only the user who needs the HA system can connect the HA communication circuit 102 to the power supply device 101. It will be good.

非絶縁回路構成の電源装置において、ＨＡシステムを用いるためのＨＡ通信回路を別基板としない場合には、当該ＨＡ通信回路分だけパターン間距離を確保する必要がある。つまり、本来、ＨＡシステムが不要なユーザに対しても、上記パターン間距離を確保する必要がある。 In a power supply device having a non-isolated circuit configuration, when the HA communication circuit for using the HA system is not used as a separate substrate, it is necessary to secure the inter-pattern distance for the HA communication circuit. That is, it is necessary to secure the distance between the patterns even for a user who originally does not need an HA system.

しかしながら、ＨＡ通信回路１０２を電源装置１０１に対して着脱自在な別基板とすることで、メイン基板である電源装置１０１において、ＨＡ通信回路分だけパターン間距離を確保する必要がない。 However, by using the HA communication circuit 102 as a separate board that can be attached to and detached from the power supply device 101, it is not necessary to secure the inter-pattern distance for the HA communication circuit in the power supply device 101 that is the main board.

そして、上記構成の電源装置１０１を備えたエアコンの室内機であれば、ＨＡシステムを用いる場合の室内機の新規設置を容易にできるだけなく、既にＨＡシステムを使用しているエアコンの室内機に容易に且つ早く取り替えることができる。これは、室内機を取り替えて、電源装置１０１に別基板であるＨＡ通信回路１０２を取付けるだけで、ＨＡシステムを直ぐに利用できるためである。 If the indoor unit of the air conditioner is equipped with the power supply device 101 having the above configuration, not only can the new indoor unit be easily installed when the HA system is used, but also the indoor unit of the air conditioner that already uses the HA system can be easily installed. It can be replaced quickly. This is because the HA system can be used immediately by simply replacing the indoor unit and attaching the HA communication circuit 102, which is a separate board, to the power supply device 101.

なお、本実施形態では、非絶縁回路構成の電源装置１０１をエアコン１の室内機に搭載し、当該電源装置１０１に取付ける絶縁回路としてＨＡ通信回路１０２を用いた例について説明したが、取付ける絶縁回路としては、ＰＣＩ（プラズマクラスターイオン）発生回路、リモコン受光回路等の他の絶縁が必要な負荷回路であってもよい。 In the present embodiment, an example in which the power supply device 101 having a non-insulated circuit configuration is mounted on the indoor unit of the air conditioner 1 and the HA communication circuit 102 is used as the insulating circuit to be attached to the power supply device 101 has been described. This may be a load circuit that requires other insulation such as a PCI (plasma cluster ion) generation circuit or a remote control light receiving circuit.

また、上記構成の電源装置１０１では、ＨＡ通信回路１０２等の絶縁が必要な負荷回路を別基板としているため、エアコン１の室内機に搭載することは好適であるが、室外機のようにユーザが直接触れる機会が極めて少ないような機器の電源装置に適用してもよい。 Further, in the power supply device 101 having the above configuration, since the load circuit that requires insulation such as the HA communication circuit 102 is used as a separate substrate, it is preferable to mount it on the indoor unit of the air conditioner 1, but the user like the outdoor unit. It may be applied to the power supply device of the device in which the chance of direct contact is extremely small.
