Description

本発明は空気調和機、特にはその室外機に関し、さらに詳しく言えば、電気部品の電装品ユニットへの取り付け構造に関するものである。   The present invention relates to an air conditioner, and more particularly to an outdoor unit thereof, and more particularly to a structure for mounting an electrical component to an electrical component unit.

室外機の電装品ユニットには、圧縮機を駆動するための種々の電気部品が設けられているが、その一つとしてリアクタがある。リアクタは、インバータにより圧縮機を駆動する際に発生するノイズを低減するために用いられるが、積層鉄心に銅線コイルを巻回した構造であることから比較的大型で重量もある。   The electrical component unit of the outdoor unit is provided with various electrical components for driving the compressor, one of which is a reactor. The reactor is used to reduce noise generated when the compressor is driven by the inverter, but is relatively large and heavy because of the structure in which the copper wire coil is wound around the laminated iron core.

そのため、多くの場合、リアクタは、電装品ユニットに金属製の専用ブラケットを介して固定される(例えば、特許文献1参照)。   Therefore, in many cases, the reactor is fixed to the electrical component unit through a metal dedicated bracket (see, for example, Patent Document 1).

ところで、図4に示すように、リアクタ1とともに大電流遮断用のリレー2を付設する場合、電装品ユニットのスペースは限られているため、リアクタ固定用のブラケット3にリレー固定台4を連設して、そこにリレー2をネジ止めするようにしている。   By the way, as shown in FIG. 4, when the relay 2 for interrupting a large current is provided together with the reactor 1, the space for the electrical component unit is limited, so the relay fixing base 4 is connected to the bracket 3 for fixing the reactor. Then, the relay 2 is screwed there.

しかしながら、リレー2をブラケット3のリレー固定台4にネジ止めする場合、リレー2をリレー固定台4に押し当てて押さえながらネジ止めする必要があるため、作業性がよくない。   However, when the relay 2 is screwed to the relay fixing base 4 of the bracket 3, the workability is not good because it is necessary to press the relay 2 against the relay fixing base 4 and press and hold it.

特開平6−137610号公報JP-A-6-137610

そこで、本発明の課題は、リレーの電装品ユニットへの取り付けを容易に行うことができるようにすることにある。   Then, the subject of this invention is enabling it to attach to the electrical component unit of a relay easily.

上記課題を解決するため、本発明は、圧縮機駆動用の電気部品を有する電装品ユニットを含む室外機を備え、上記電装品ユニットにリアクタ固定台を有するブラケットが取り付けられている空気調和機において、
上記ブラケットには、上記リアクタ固定台に隣接してリレーを固定するリレー固定台が設けられており、上記リレー固定台には、上記リレーを固定する位置に保持する仮止め手段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 present invention provides an air conditioner including an outdoor unit including an electrical component unit having electrical components for driving a compressor, and a bracket having a reactor fixing base attached to the electrical component unit. ,
The bracket is provided with a relay fixing base for fixing a relay adjacent to the reactor fixing base, and the relay fixing base is provided with a temporary fixing means for holding the relay in a position for fixing. It is characterized by that.

本発明の好ましい態様によると、上記仮止め手段は、少なくとも上記リレーの上下2箇所を保持する係止爪を備えている。   According to a preferred aspect of the present invention, the temporary fixing means includes a locking claw for holding at least two upper and lower positions of the relay.

また、上記係止爪は、上記リレー固定台から切り起こされた爪であることが好ましい。   Moreover, it is preferable that the said latching claw is a nail | claw cut and raised from the said relay fixing stand.

本発明によれば、リレー固定台のリレーを固定する位置にリレーを保持する仮止め手段(好ましくはリレー固定台から切り起こされた係止爪)を設けたことにより、リレー固定台にリレーを固定するにあたって、リレーを押さえておく必要がなく、リレーの固定作業を容易に行うことができる。   According to the present invention, the provision of the temporary fixing means (preferably the locking claw cut and raised from the relay fixing base) for holding the relay at the position for fixing the relay of the relay fixing base allows the relay to be fixed to the relay fixing base. In fixing, it is not necessary to hold the relay, and the fixing work of the relay can be easily performed.

次に、図1ないし図3により、本発明の実施形態について説明するが、本発明はこれに限定されるものではない。   Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3, but the present invention is not limited to this.

図1ないし図3を参照して、本発明では、図1に示すブラケット10を用いてリアクタ1とリレー2を電装品ユニット5に設置する。なお、図2には電装品ユニット5の一部のみが示されている。   With reference to FIG. 1 thru | or FIG. 3, in this invention, the reactor 1 and the relay 2 are installed in the electrical component unit 5 using the bracket 10 shown in FIG. FIG. 2 shows only a part of the electrical component unit 5.

ブラケット10は好ましくは金属製であり、この実施形態では、図2に示すように、ブラケット10は、電装品ユニット5の一部を構成する例えば室外機内を熱交換室と機械室とに仕切る仕切板5aに取り付けられるが、これ以外の例えば上記機械室内の所定の支持部材(支持板)に取り付けられてもよい。   The bracket 10 is preferably made of metal. In this embodiment, as shown in FIG. 2, the bracket 10 is a partition that forms a part of the electrical component unit 5, for example, an interior of an outdoor unit divided into a heat exchange chamber and a machine room. Although it is attached to the plate 5a, it may be attached to a predetermined support member (support plate) other than this, for example, in the machine room.

ブラケット10には、リアクタ1を固定するリアクタ固定台11と、リレー2を固定するリレー固定台13とが含まれている。リアクタ固定台11とリレー固定台13は、1枚の金属板のプレス加工により一体に形成することができる。   The bracket 10 includes a reactor fixing base 11 that fixes the reactor 1 and a relay fixing base 13 that fixes the relay 2. The reactor fixing base 11 and the relay fixing base 13 can be integrally formed by pressing one metal plate.

この実施形態において、ブラケット10の上部にリアクタ固定台11が配置され、ブラケット10の下部にリレー固定台13が配置されているが、リアクタ固定台11の上辺、リレー固定台13の下辺およびリアクタ固定台11とリレー固定台13の間には、それぞれ、仕切板5a側に向けて折り曲げられた支持脚101,102,103が形成されており、これら支持脚101,102,103により、リアクタ固定台11およびリレー固定台13は、ともに仕切板5aとの間で所定間隔の空隙が生ずるように仕切板5aに取り付けられる。   In this embodiment, the reactor fixing base 11 is arranged at the upper part of the bracket 10 and the relay fixing base 13 is arranged at the lower part of the bracket 10. However, the upper side of the reactor fixing base 11, the lower side of the relay fixing base 13, and the reactor fixing Support legs 101, 102, and 103 are formed between the base 11 and the relay fixing base 13 so as to be bent toward the partition plate 5 a side. The support legs 101, 102, and 103 form the reactor fixing base. 11 and the relay fixing base 13 are both attached to the partition plate 5a so that a gap of a predetermined interval is generated between the partition plate 5a and the relay support base 13.

リアクタ固定台11の下方には、リアクタ1が有する四角形状の支持基板1aの下辺両端が上方から嵌合される受け溝部111(111a,111b)が左右2箇所に設けられている。   Below the reactor fixing base 11, receiving groove portions 111 (111 a and 111 b) in which the lower ends of the rectangular support substrate 1 a of the reactor 1 are fitted from above are provided at two positions on the left and right.

この例において、左側の受け溝部111aと右側の受け溝部111bはともにプレス加工により四角台形状に形成されるが、左側の受け溝部111aは、上辺および右側辺がリアクタ固定台11から切り離されるように形成され、右側の受け溝部111bは、上辺および左側辺がリアクタ固定台11から切り離されるように形成される。   In this example, the left receiving groove 111a and the right receiving groove 111b are both formed into a square trapezoidal shape by pressing, but the left receiving groove 111a is separated from the reactor fixing base 11 at the upper side and the right side. The right receiving groove 111b is formed such that the upper side and the left side are separated from the reactor fixing base 11.

リレー固定台13には、リレー2を固定する位置に保持する仮止め手段131が設けられている。この実施形態において、仮止め手段131は、リレー固定台13から切り起こされた係止爪131aからなる。   The relay fixing base 13 is provided with temporary fixing means 131 for holding the relay 2 at a position for fixing. In this embodiment, the temporary fixing means 131 includes a locking claw 131 a cut and raised from the relay fixing base 13.

この実施形態において、係止爪131aは、リレー2をリレー2の筐体2aの上面中央部の1箇所と、筐体2aの下面の左右2箇所の合計3箇所で挟んで保持できる位置に配置されているが、少なくとも筐体2aの上下2箇所で挟んで保持できる位置に配置されていればよい。   In this embodiment, the locking claw 131a is arranged at a position where the relay 2 can be held between a total of three locations, one at the center of the upper surface of the housing 2a of the relay 2 and two at the left and right of the lower surface of the housing 2a. However, it should just be arrange | positioned in the position which can be pinched | interposed and hold | maintained at the upper and lower two places of the housing | casing 2a.

また、リレー2の筐体2aの左右両側辺には耳板2bが一体に形成されており、その各々には、ほぼU字状をなすネジ挿通溝2cが形成されている。これ対応して、リレー固定台13の左右2箇所には、リレー2をネジ止めするための雌ネジ孔132が設けられている。   Further, ear plates 2b are integrally formed on the left and right sides of the housing 2a of the relay 2, and screw insertion grooves 2c each having a substantially U shape are formed in each of the ear plates 2b. Correspondingly, female screw holes 132 for screwing the relay 2 are provided at two positions on the left and right sides of the relay fixing base 13.

このブラケット10によれば、リアクタ1をリアクタ固定部11にネジ止めすることができるとともに、リレー2をリレー固定部13にネジ止めすることができるが、特にリレー2をリレー固定部13にネジ止めする際、リレー2が係止爪131aにより固定する位置に保持され、リレー2から両手を離してもリレー2が落下することがないため、リレー2を押さえながらネジ止めする必要がなくなり、リレーのネジ止め作業を容易に行うことができる。   According to this bracket 10, the reactor 1 can be screwed to the reactor fixing portion 11 and the relay 2 can be screwed to the relay fixing portion 13. In particular, the relay 2 is screwed to the relay fixing portion 13. The relay 2 is held at a position where the relay 2 is fixed by the locking claw 131a, and the relay 2 does not fall even if both hands are released from the relay 2. Therefore, it is not necessary to screw the relay 2 while holding the relay 2. Screwing work can be easily performed.

また、リアクタ固定部11およびリレー固定部13は、その背面側が仕切り板5aから離されているため放熱性にも優れている。   Moreover, since the reactor fixing | fixed part 11 and the relay fixing | fixed part 13 are separated from the partition plate 5a in the back side, they are excellent also in heat dissipation.
