Description

本発明は、電子部品を実装した配線基板を収納するための配線基板保持装置を備えた空気調和機の室内機に関するものである。 The present invention relates to an indoor unit of an air conditioner provided with a wiring board holding device for accommodating a wiring board on which electronic components are mounted.

従来、空気調和機の室内機は、外郭を形成する筐体の内部に、複数のコネクタ及び電子部品が実装された配線基板を収納するための配線基板保持装置を備えた構成が知られている。配線基板保持装置は、一例として、配線基板を保持する凹形状のベースフレームと、ベースフレームの開口面を塞ぐカバー部材とで構成されている。 Conventionally, it is known that an indoor unit of an air conditioner is provided with a wiring board holding device for accommodating a wiring board on which a plurality of connectors and electronic components are mounted inside a housing forming an outer shell. .. As an example, the wiring board holding device is composed of a concave base frame that holds the wiring board and a cover member that closes the opening surface of the base frame.

配線基板のコネクタには、ベースフレームの外部から通した高電圧線と低電圧線とが接続される場合がある。高電圧線と低電圧線は、ベースフレームの凹部内に設けられた配線経路を通じてコネクタに接続されるが、近接しているとノイズが発生するため、一定の距離をあけて配線される。 A high-voltage line and a low-voltage line passed from the outside of the base frame may be connected to the connector of the wiring board. The high-voltage line and the low-voltage line are connected to the connector through a wiring path provided in the recess of the base frame, but noise is generated when they are close to each other, so they are wired at a certain distance.

例えば特許文献１には、同一の配線経路内において、ワイヤーハーネスを構成する複数の電線中の特定の電線を流れる信号等が、他の電線を流れる電流等の干渉を受ける事態を防止する構成が開示されている。 For example, Patent Document 1 has a configuration for preventing a signal or the like flowing through a specific electric wire in a plurality of electric wires constituting a wire harness from being interfered with by a current or the like flowing through another electric wire in the same wiring path. It is disclosed.

実開平５−４８５３３号公報Jikkenhei 5-48533

特許文献１に開示された発明では、ワイヤーハーネスを構成する複数の電線を同一の配線経路内に配線する構成なので、該配線経路内に高電圧線と低電圧線とを配線した場合、ノイズの発生を抑制できない虞がある。ノイズの発生を抑制できる程度に間隔をあけて高電圧線と低電圧線を配線するには、配線経路を無駄に大きくせざるを得ない。つまり、特許文献１に係る発明を空気調和機の室内機に適用し、高電圧線と低電圧線のノイズの発生を抑制する構成にすると、配線経路が大きくなってしまうことで、他の様々な機能を追加するスペースが制限されてしまい、多機能を備えた室内機の実現が困難となる。 In the invention disclosed in Patent Document 1, since a plurality of electric wires constituting the wire harness are wired in the same wiring path, noise is generated when the high voltage line and the low voltage line are wired in the wiring path. There is a risk that the occurrence cannot be suppressed. In order to wire the high-voltage line and the low-voltage line at intervals that can suppress the generation of noise, the wiring path must be unnecessarily large. That is, if the invention according to Patent Document 1 is applied to an indoor unit of an air conditioner and is configured to suppress the generation of noise in high-voltage lines and low-voltage lines, the wiring path becomes large, and various other methods The space for adding various functions is limited, and it becomes difficult to realize an indoor unit equipped with multiple functions.

本発明は、上記のような課題を解決するためになされたもので、配線経路を大きくすることなく、高電圧線と低電圧線のノイズの発生を抑制できる、空気調和機の室内機を提供することを目的とする。 The present invention has been made to solve the above problems, and provides an indoor unit of an air conditioner capable of suppressing the generation of noise in high-voltage lines and low-voltage lines without increasing the wiring path. The purpose is to do.

本発明に係る空気調和機の室内機は、外郭を形成する筐体と、前記筐体の内部に配置され、電子部品を実装した配線基板を収納する配線基板保持装置と、を備え、前記配線基板保持装置は、前記配線基板を保持する凹形状のベースフレームと、前記ベースフレームの開口面を塞ぐカバー部材と、を有し、前記ベースフレームは、凹部内を、外部から通した第１配線の第１配線経路と、前記配線基板が嵌め込まれる領域と、に区画する基板支持壁と、前記基板支持壁から前記配線基板が嵌め込まれる領域に向かって突き出し、外部から通した第２配線の第２配線経路を形成する保持部と、が設けられ、前記第１配線と前記第２配線とが、前記基板支持壁を隔てて前記ベースフレームの内部に配線されるものである。 The indoor unit of the air conditioner according to the present invention includes a housing that forms an outer shell and a wiring board holding device that is arranged inside the housing and houses a wiring board on which electronic components are mounted. The board holding device has a concave base frame for holding the wiring board and a cover member for closing the opening surface of the base frame, and the base frame has a first wiring that passes through the recess from the outside. A second wiring that is divided into a first wiring path and a region in which the wiring board is fitted, and a second wiring that protrudes from the board support wall toward a region in which the wiring board is fitted and is passed from the outside. A holding portion for forming the two wiring paths is provided, and the first wiring and the second wiring are wired inside the base frame with the substrate support wall interposed therebetween .

本発明に係る空気調和機の室内機によれば、外部から通した第１配線と外部から通した第２配線とを、基板支持壁を隔ててベースプレートの内部に配線する構成なので、第１配線を高電圧線とし、第２配線を低電圧線とした場合、基板支持壁でノイズの発生を抑制することができる。また、本発明に係る空気調和機の室内機は、配線基板が嵌め込まれる領域に第２配線を配線するので、第１配線を通す第１配線経路が大きくなることもない。 According to the indoor unit of the air conditioner according to the present invention, the first wiring passed from the outside and the second wiring passed from the outside are wired inside the base plate with the substrate support wall separated. When the high voltage line is used and the second wiring is a low voltage line, the generation of noise can be suppressed at the substrate support wall. Further, in the indoor unit of the air conditioner according to the present invention, since the second wiring is wired in the region where the wiring board is fitted, the first wiring path through which the first wiring is passed does not become large.

That is, the concave interior surrounded by the substrate support wall 8 and the lower wall surface 60 is configured as the first wiring path 61 for passing the first wiring 90. As shown in FIG. 9, the opening surface of the first wiring path 61 is closed by attaching the cover member 7 to the base frame 6.

ベースフレーム６及び基板支持壁８には、配線基板５が嵌め込まれる領域６２を形成する壁面に、配線基板５を固定するための嵌合突部５ａが設けられている。嵌合突部５ａは、配線基板５の板厚と略同程度の幅寸からなる嵌合溝が形成されており、この嵌合溝に配線基板５の縁部が嵌め込まれる構成である。嵌合突部５ａは、配線基板５が嵌め込まれる領域６２の周方向に沿って間隔をあけて複数設けられている。 The base frame 6 and the substrate support wall 8 are provided with a fitting protrusion 5a for fixing the wiring board 5 on the wall surface forming the region 62 into which the wiring board 5 is fitted. The fitting protrusion 5a is formed with a fitting groove having a width approximately equal to the thickness of the wiring board 5, and the edge portion of the wiring board 5 is fitted into the fitting groove. A plurality of fitting protrusions 5a are provided at intervals along the circumferential direction of the region 62 into which the wiring board 5 is fitted.

また、ベースフレーム６には、図７〜図９に示すように、基板支持壁８から配線基板５が嵌め込まれる領域６２に向かって突き出し、当該領域６２に、外部から通した第２配線９１の第２配線経路６３を形成する保持部８０が設けられている。保持部８０は、基板支持壁８の長手方向に沿って間隔をあけて配置された第１保持部８０ａと第２保持部８０ｂとで構成されている。 Further, as shown in FIGS. 7 to 9, the base frame 6 protrudes from the substrate support wall 8 toward the region 62 into which the wiring board 5 is fitted, and the second wiring 91 is passed through the region 62 from the outside. A holding portion 80 that forms the second wiring path 63 is provided. The holding portion 80 is composed of a first holding portion 80a and a second holding portion 80b arranged at intervals along the longitudinal direction of the substrate support wall 8.

第１保持部８０ａは、基板支持壁８の端縁部からベースフレーム６の開口面に向かって延出され、延出した端部から配線基板５が嵌め込まれる領域６２に向かって突き出す形状から成る。第２保持部８０ｂは、基板支持壁８の端縁部から配線基板５が嵌め込まれる領域６２に向かって突き出し、突き出した端縁部からベースフレーム６の開口面に向かって延出させた形状から成る。つまり、第２配線経路６３は、図９に示すように、側面方向から見て、第１保持部８０ａと第２保持部８０ｂとで囲まれた領域によって形成されている。なお、第１保持部８０ａと第２保持部８０ｂとを間隔をあけて配置している理由は、第２配線９１を第２配線経路６３に通しやすくするためであり、配線取り回し作業の作業性を高めるためである。また、保持部８０は、第２保持部８０ｂを配線基板保持装置４の右側面側に配置し、第１保持部８０ａを配線基板保持装置４の左側面側に配置した構成に限定されず、第２保持部８０ｂを配線基板保持装置４の左側面側に配置し、第１保持部８０ａを配線基板保持装置４の右側面側に配置した構成でもよい。 The first holding portion 80a has a shape that extends from the edge portion of the substrate support wall 8 toward the opening surface of the base frame 6 and projects from the extending end portion toward the region 62 into which the wiring board 5 is fitted. .. The second holding portion 80b has a shape that protrudes from the edge portion of the substrate support wall 8 toward the region 62 into which the wiring board 5 is fitted and extends from the protruding edge portion toward the opening surface of the base frame 6. Become. That is, as shown in FIG. 9, the second wiring path 63 is formed by a region surrounded by the first holding portion 80a and the second holding portion 80b when viewed from the side surface direction. The reason why the first holding portion 80a and the second holding portion 80b are arranged at intervals is to facilitate the passage of the second wiring 91 through the second wiring path 63, and the workability of the wiring routing work This is to increase. Further, the holding portion 80 is not limited to the configuration in which the second holding portion 80b is arranged on the right side surface side of the wiring board holding device 4 and the first holding portion 80a is arranged on the left side surface side of the wiring board holding device 4. The second holding portion 80b may be arranged on the left side surface side of the wiring board holding device 4, and the first holding portion 80a may be arranged on the right side surface side of the wiring board holding device 4.

配線基板保持装置４の右側面には、図６に示すように、第１配線経路６１に通じる第１開口部９２と、第２配線経路６３に通じる第２開口部９３とが形成されている。第１開口部９２は、ベースフレーム６及びカバー部材７のそれぞれに形成した切り欠き状の開口を組み合わせた構成である。同様に、第２開口部９３も、ベースフレーム６及びカバー部材７のそれぞれに形成した切り欠き状の開口を組み合わせた構成である。なお、第１開口部９２及び第２開口部９３は、ベースフレーム６又はカバー部材７の一方にのみ形成した構成でもよい。 As shown in FIG. 6, a first opening 92 leading to the first wiring path 61 and a second opening 93 leading to the second wiring path 63 are formed on the right side surface of the wiring board holding device 4. .. The first opening 92 is a combination of notch-shaped openings formed in each of the base frame 6 and the cover member 7. Similarly, the second opening 93 also has a configuration in which notch-shaped openings formed in the base frame 6 and the cover member 7 are combined. The first opening 92 and the second opening 93 may be formed only on one of the base frame 6 and the cover member 7.

第１配線９０は、一例として電源線及び駆動モーター等の高電圧線であり、第１開口部９２を通じて第１配線経路６１に通される。第１配線経路６１に通した第１配線９０は、基板支持壁８に形成された切り欠き孔から配線基板５が嵌め込まれた領域６２へ通され、配線基板５の対応するコネクタ５０に接続される。また、第２配線９１は、一例としてセンサー線等の低電圧線であり、第２開口部９３を通じて第２配線経路６３に通され、配線基板５の対応するコネクタ５０に接続される。なお、電線は、第１配線９０を低電圧線とし、第２配線９１を高電圧線としてもよい。 The first wiring 90 is, for example, a power supply line and a high voltage line of a drive motor or the like, and is passed through the first wiring path 61 through the first opening 92. The first wiring 90 passed through the first wiring path 61 is passed through the notch hole formed in the substrate support wall 8 to the region 62 in which the wiring board 5 is fitted, and is connected to the corresponding connector 50 of the wiring board 5.
