Description

本発明は、空気調和装置の室外機に係り、特に電気部品箱における端子台とスイッチ基板との取付け構造の改良に関する。   The present invention relates to an outdoor unit of an air conditioner, and more particularly to an improvement in a mounting structure between a terminal block and a switch board in an electrical component box.

室内機と室外機とを、冷媒管およびリード線を介して接続してなる分離型の空気調和装置が多用されている。特に、室外機には、筐体である室外機本体内に、圧縮機と、熱交換器と、この熱交換器に対向して配置される送風機などが収容される。さらに、室外機本体内には電気部品箱が取付けられていて、ここには圧縮機、送風機などを駆動制御するための制御部品が装着される制御基板と、電源供給用電線の端子および制御基板接続用電線の端子が取付けられる端子台が収容される。   2. Description of the Related Art A separate type air conditioner in which an indoor unit and an outdoor unit are connected via a refrigerant pipe and a lead wire is frequently used. In particular, the outdoor unit accommodates a compressor, a heat exchanger, a blower disposed to face the heat exchanger, and the like in an outdoor unit body that is a casing. Furthermore, an electrical component box is mounted in the outdoor unit main body. Here, a control board on which control parts for driving and controlling a compressor, a blower and the like are mounted, a terminal of the power supply electric wire, and a control board A terminal block to which the terminal of the connecting wire is attached is accommodated.

たとえば、［特許文献１］には、制御基板を主基板と補助基板とに分離し、補助基板に設定スイッチを設けている。上記補助基板を電気部品箱の側面に取付け、設定スイッチを操作し易い向きに配置できるようにしたことを特徴とする空気調和装置の室外機が開示されている。上記設定スイッチは、たとえばパワーセーブモード運転、既設配管運転モード等の各種の運転モードに対応させるための切換えスイッチである。   For example, in [Patent Document 1], a control board is separated into a main board and an auxiliary board, and a setting switch is provided on the auxiliary board. There is disclosed an outdoor unit for an air conditioner characterized in that the auxiliary board is attached to a side surface of an electric component box and the setting switch can be arranged in an easy-to-operate direction. The setting switch is a changeover switch for corresponding to various operation modes such as a power save mode operation and an existing pipe operation mode.

特開２００２−１０６８８７号公報JP 2002-106887 A

ところで、上述の［特許文献１］の技術では、端子台が上記設定スイッチを取付けた補助基板に隣接して設けられている。この端子台の正面視面積および電気部品箱側面からの突出量と比較して、上記補助基板の正面視面積および設定スイッチの電気部品箱側面からの突出量が極くわずかでしかない。
そのため、補助基板の取付けを端子台の取付けの後に行うと、端子台が邪魔になって作業性が悪い。作業順序を予め決めなければならず、手間がかかる。補助基板が取付けられた状態で、設定スイッチと端子台とは極く接近した位置にある。そのため、設定スイッチを操作する際に誤って手が端子台に触れ、作業性が悪い。さらには、電線端子の取付け部に直接、手が触れると感電の虞れがある。 By the way, in the technique of the above-mentioned [Patent Document 1], the terminal block is provided adjacent to the auxiliary board to which the setting switch is attached. Compared with the front view area of the terminal block and the protruding amount from the side of the electric component box, the front view area of the auxiliary board and the protruding amount of the setting switch from the side of the electric component box are very small.
Therefore, if the auxiliary board is attached after the terminal block is attached, the terminal block becomes an obstacle and the workability is poor. The work order must be determined in advance, which takes time. With the auxiliary board attached, the setting switch and the terminal block are in a very close position. For this reason, when operating the setting switch, the hand accidentally touches the terminal block and the workability is poor. Furthermore, there is a risk of electric shock if the hand directly touches the wire terminal mounting portion.

上記補助基板を端子台から離間した位置に取付けることができれば問題が解決するが、既に補助基板は電気部品箱の側面端部に取付けられており、ここから位置をずらすことができない。端子台においても同様に、スペース的に余裕が少なく、無理に位置をずらすと電源コード等の接続作業が行い難くなって作業性が低下してしまう。   The problem can be solved if the auxiliary board can be mounted at a position away from the terminal block, but the auxiliary board is already mounted on the side edge of the electric component box, and the position cannot be shifted from here. Similarly, in the terminal block, there is not enough space, and if the position is forcibly shifted, it is difficult to connect the power cord and the like, and the workability is lowered.

本発明は上述した事情を考慮してなされたものであり、その目的とするところは、設定スイッチの取付けを簡単にした構成を備え、設定スイッチの操作を安全に行える空気調和装置の室外機を提供しようとするものである。   The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide an outdoor unit of an air conditioner that has a configuration in which the setting switch can be easily attached and can safely operate the setting switch. It is something to be offered.

上記目的を達成するため本発明は、筐体である室外機本体の内部に、圧縮機と、熱交換器と、この熱交換器に対向して配置される送風機および、圧縮機、送風機などを駆動制御するための制御部品が装着される制御基板等を収納する電気部品箱とを具備した空気調和装置の室外機において、
室外機本体の一側面に開口され配線蓋によって開閉される配線用開口部と、この配線用開口部と対向して開口端を有する上記電気部品箱と、この電気部品箱の開口端と室外機本体の配線用開口部との間に介在される端子台ベースと、この端子台ベースに取付けられ配線用開口部側に電源供給用電線の端子が取付けられる第１の接続部および電気部品箱側に制御基板と電気的に接続する電線の端子が取付けられる第２の接続部を互いに並列に備えた端子台と、さらに端子台ベースに取付けられ端子台の第２の接続部を覆うカバー部を備え、カバー部から離間した位置で、かつ上方へ突出し箱型をなすスイッチ固定部が設けられるカバー本体と、このカバー本体に着脱自在に取付けられ端子台の第１の接続部を覆う端子カバーと、カバー本体の上記スイッチ固定部内に収容され、スイッチ固定部の外部から手動操作可能な設定スイッチを備えたスイッチ基板とを具備する。 In order to achieve the above object, the present invention provides a compressor, a heat exchanger, a blower disposed opposite to the heat exchanger, a compressor, a blower, and the like inside an outdoor unit body that is a casing.

FIG. 6 is a partial cross-sectional plan view of the cover main body 30.

上記電気部品箱１０は前面一部が開口する箱体であり、この天板部１０ａが室外機本体１の天板１ａとほとんど接触するよう室外機本体１に取付けられる。天板部１０ａの裏面側全面に亘って制御基板１１が取付けられる。上記制御基板１１には、送風機３、圧縮機７等の電動部品を駆動制御するための制御部品が実装される。   The electric component box 10 is a box whose front part is open, and is attached to the outdoor unit main body 1 so that the top plate part 10a is almost in contact with the top plate 1a of the outdoor unit main body 1. The control board 11 is attached over the entire back surface side of the top plate portion 10a. On the control board 11, control parts for driving and controlling electric parts such as the blower 3 and the compressor 7 are mounted.

すなわち、制御基板１１における長手方向の一側辺部には発熱量が大きく、放熱フィン１２を備えたパワートランジスタモジュール等が実装され、制御基板１１の下面側（反天板側）には、電解コンデンサ等の電気部品が実装される。
電気部品箱１０の一側面には複数の孔部からなる通気孔１３が設けられ、かつ電気部品箱１０内部にはスロープ１４が設けられる。このスロープ１４は耐燃性の合成樹脂材からなり、電気部品箱１０の前面開口端から電気部品が実装される底部に向かって電気部品箱１０内に形成される空気流通路の高さ（幅）を狭くするように設けられる。 That is, a large amount of heat is generated on one side portion in the longitudinal direction of the control board 11, and a power transistor module or the like including the radiation fins 12 is mounted. Electrical components such as capacitors are mounted.
A vent hole 13 having a plurality of holes is provided on one side surface of the electric component box 10, and a slope 14 is provided inside the electric component box 10. The slope 14 is made of a flame-resistant synthetic resin material, and the height (width) of the air flow passage formed in the electric component box 10 from the front opening end of the electric component box 10 toward the bottom where the electric component is mounted. Is provided so as to be narrow.

上記室外機本体１の一側面には配線用開口部１５が設けられていて、ここには配線蓋１６が複数の取付けネジを介して取付けられる。配線蓋１６の上部側における室外機本体１側面には、室外機運搬時に用いられる把手部１７が一体に成形され、上記配線蓋１６には把手部１７の逃げをなす湾曲部１８が凹陥形成される。   A wiring opening 15 is provided on one side surface of the outdoor unit main body 1, and a wiring lid 16 is attached thereto via a plurality of mounting screws. On the side of the outdoor unit body 1 on the upper side of the wiring lid 16, a handle portion 17 that is used when the outdoor unit is transported is integrally formed. The

上記配線蓋１６の湾曲部１８下部には複数の孔部からなる通気孔１９が設けられ、外部空気がこれら通気孔１９を介して室外機本体１内へ導入されるようになっている。さらに配線蓋１６には、外部電線を通すための外部電線導入部２０が形成される。   A vent hole 19 composed of a plurality of holes is provided below the curved portion 18 of the wiring lid 16, and external air is introduced into the outdoor unit main body 1 through the vent holes 19. Further, the wiring lid 16 is formed with an external electric wire introduction portion 20 for passing an external electric wire.

特に、図２に示すように、上記配線蓋１６を室外機本体１から取外すと、配線用開口部１５から端子台ベース２１の一部と、この端子台ベース２１に取付けられるカバー本体３０および端子カバー４０が露出する。端子台ベース２１には端子台２２も取付けられているが、この端子台２２は上記カバー本体３０および端子カバー４０によって覆われていて、これらを取外すことによってはじめて露出する。   In particular, as shown in FIG. 2, when the wiring cover 16 is removed from the outdoor unit main body 1, a part of the terminal block base 21 from the wiring opening 15, the cover main body 30 attached to the terminal block base 21, and the terminals The cover 40 is exposed. Although the terminal block 22 is also attached to the terminal block base 21, this terminal block 22 is covered with the said cover main body 30 and the terminal cover 40, and is exposed only after removing these.

なお説明すると、上記端子台ベース２１は、電気部品箱１０開口端から水平方向に突出する水平部２１ａと、この水平部２１ａの端部から斜め下方に折り曲げられ傾斜部２１ｂとからなる。傾斜部２１ｂの先端は室外機本体１側面に設けられる配線用開口部１５の下端近傍まで延出され、この傾斜部２１ｂに上記端子台２２が取付けられる。   In other words, the terminal block base 21 includes a horizontal portion 21a that protrudes in the horizontal direction from the opening end of the electrical component box 10, and an inclined portion 21b that is bent obliquely downward from the end portion of the horizontal portion 21a. The tip of the inclined portion 21b extends to the vicinity of the lower end of the wiring opening 15 provided on the side surface of the outdoor unit body 1, and the terminal block 22 is attached to the inclined portion 21b.

上記端子台ベース２１における傾斜部２１ｂの幅寸法は、配線用開口部１５の幅寸法よりも若干大きめに設けられ、水平部２１ａの幅寸法は、傾斜部２１ｂの幅よりも狭く設けられていて、電気部品箱１０に対する配線作業の邪魔とならないように成形されている。
上記端子台２２は、第１の接続部２２ａと第２の接続部２２ｂが並列に、２列備えられる。第１の接続部２２ａには外部から延出される電源供給用の電線の端子が取付けられ、第２の接続部２２ｂには電気部品箱１０内の制御基板１１と接続する電線の端子が取付けられる。したがって、第１の接続部２２ａは第２の接続部２２ｂよりも大きく成形され、各接続端子を区画する隔壁２２ｃも大である。 In the terminal base 21, the width of the inclined portion 21b is slightly larger than the width of the wiring opening 15, and the width of the horizontal portion 21a is narrower than the width of the inclined portion 21b. The electric component box 10 is molded so as not to interfere with the wiring work.
The terminal block 22 includes two rows of first connection portions 22a and second connection portions 22b in parallel. A terminal of a power supply electric wire extending from the outside is attached to the first connecting portion 22a, and a terminal of an electric wire connected to the control board 11 in the electric component box 10 is attached to the second connecting portion 22b. . Accordingly, the first connection portion 22a is formed larger than the second connection portion 22b, and the partition 22c that partitions each connection terminal is also large.

端子台２２の両側端部にはカバー本体取付け部２２ｄが設けられ、ここに上記カバー本体３０の両側部に形成される脚部３１が嵌め込まれる。脚部３１には、ネジ孔を備えた取付け座３１ａが一体に成形され、取付けネジを介して端子台ベース２１の傾斜部２１ｂに取付け固定される。   Cover body attachment portions 22d are provided at both end portions of the terminal block 22, and leg portions 31 formed on both side portions of the cover body 30 are fitted therein. A mounting seat 31 a having a screw hole is integrally formed on the leg portion 31, and is fixed to the inclined portion 21 b of the terminal block base 21 through mounting screws.

カバー本体３０の脚部３１は端子台２２のカバー本体取付け部２２ｄ上端面間に亘って架設される傾斜するカバー部ａと、このカバー部ａの長手方向に沿う端縁から一体に垂直方向に折曲形成される垂直面部ｂを備えている。上記カバー部ａはカバー本体取付け部２２ｄと対向する部分を残して、第１の接続部２２ａと対向する部分は欠落加工され、第２の接続部２２ｂと対向する部分のみが残って架設状態となっている。   The leg portion 31 of the cover body 30 is integrally formed vertically from the inclined cover portion a extending over the upper end surface of the cover body mounting portion 22d of the terminal block 22 and the edge along the longitudinal direction of the cover portion a. The vertical surface part b formed by bending is provided. The cover part a leaves a part facing the cover body mounting part 22d, a part facing the first connection part 22a is cut off, and only a part facing the second connection part 22b remains and is installed. It has become.

したがって、端子台ベース２１の傾斜部２１ｂに端子台２２とカバー本体３０のみを取付けた状態で、端子台２２の第１の接続部２２ａがカバー部ａの欠落部分に対向して露出し、第２の接続部２２ｂはカバー部ａによって覆われる。
カバー部ａの欠落部分を挟んで残された両側部、すなわち脚部３１の対向部分において、一方の側部にはネジ孔を備えた取付け部３２が設けられ、他方側部には図示しない掛止用凹部を備えた掛止部３３が設けられる。 Therefore, in a state where only the terminal block 22 and the cover body 30 are attached to the inclined portion 21b of the terminal block base 21, the first connection portion 22a of the terminal block 22 is exposed to face the missing portion of the cover portion a. The two connecting portions 22b are covered with a cover portion a.
At both side portions left across the missing portion of the cover portion a, that is, the opposite portion of the leg portion 31, a mounting portion 32 having a screw hole is provided on one side portion, and the other side portion is not illustrated. A latching portion 33 having a latching recess is provided.

一方、上記端子カバー４０は、長手方向の一側部にネジ挿通用孔を備えた突部４１が設けられ、他側部に爪部４２が設けられている。カバー本体３０に端子カバー４０を取付けるには、カバー本体３０の掛止部３３に端子カバー４０の爪部４２を挿入し掛合したのち、カバー本体３０の取付け部３２に対して端子カバー４０の突部４１を位置合せし、取付けネジを螺挿すればよい。   On the other hand, the terminal cover 40 is provided with a protrusion 41 having a screw insertion hole on one side in the longitudinal direction and a claw 42 on the other side. In order to attach the terminal cover 40 to the cover main body 30, the claw portion 42 of the terminal cover 40 is inserted into the latching portion 33 of the cover main body 30 and engaged, and then the protrusion of the terminal cover 40 against the mounting portion 32 of the cover main body 30. The part 41 may be aligned and a mounting screw may be screwed.

この状態で、カバー本体３０に端子カバー４０が取付け固定され、端子台２２の第１の接続部２２ａが端子カバー４０によってカバーされる。端子カバー４０には複数の溝部４３が所定間隔を存して一体に凹陥形成されていて、これら溝部４３は第１の接続部２２ａを構成する隔壁２２ｃ相互間に挿入される。すなわち、溝部４３の存在により、第１の接続部２２ａに接続される電源供給用電線の端子がより抜け難くなる。   In this state, the terminal cover 40 is attached and fixed to the cover body 30, and the first connection portion 22 a of the terminal block 22 is covered by the terminal cover 40. A plurality of groove portions 43 are integrally formed in the terminal cover 40 with a predetermined interval, and these groove portions 43 are inserted between the partition walls 22c constituting the first connection portion 22a. In other words, the presence of the groove 43 makes it more difficult for the terminal of the power supply wire connected to the first connecting portion 22a to come off.

一方、カバー本体３０の垂直面部ｂは一部のみが上方へ突出していて、この突出部はスイッチ基板５０を取付けるためのスイッチ固定部３４となっている。上記スイッチ固定部３４は、最上部に箱型をなし、前面側が閉塞されたうえで手前側に突出するコネクタ収納部３５と、このコネクタ収納部３５の下部側で、かつ前面側において開口する、丸孔からなる第１のスイッチ操作用孔３６および、矩形状の第２のスイッチ操作用孔３７を備えている。   On the other hand, only a part of the vertical surface portion b of the cover body 30 protrudes upward, and this protrusion serves as a switch fixing portion 34 for mounting the switch substrate 50. The switch fixing part 34 has a box shape at the uppermost part, and the front side is closed and the front side is opened, and the lower side of the connector storage part 35 and the front side is opened. A first switch operation hole 36 made of a round hole and a rectangular second switch operation hole 37 are provided.

上記スイッチ固定部３４は、左右側部が所定の幅寸法に形成され、背面側は開口される。上記第１のスイッチ操作用孔３６と同一高さの両側部には左右一対の固定爪３８が設けられていて、先端の爪部ｄは弾性変形自在である。
このカバー本体３０に一体成形されるスイッチ固定部３４に、上記スイッチ基板５０が取付けられる。すなわち、スイッチ基板５０はスイッチ固定部３４を構成するコネクタ収納部３５と下部に亘る背面の開口から内部に挿入される。 The switch fixing portion 34 has left and right side portions formed in a predetermined width dimension, and the back side is opened. A pair of left and right fixing claws 38 are provided on both sides of the same height as the first switch operation hole 36, and the claw portion d at the tip is elastically deformable.
The switch board 50 is attached to the switch fixing portion 34 that is integrally formed with the cover body 30. That is, the switch board 50 is inserted into the connector housing part 35 constituting the switch fixing part 34 and the opening on the back surface extending to the lower part.

スイッチ基板５０の前面に上部からコネクタ５１と、第１のスイッチ５２および第２のスイッチ５３が所定間隔を存して実装される。これら部品を実装したスイッチ基板５０をスイッチ固定部３４の背面開口部から内部に挿入すると、上記固定爪３８の先端爪部ｄにスイッチ基板５０の側縁が当接する。さらにスイッチ基板５０を押し込むと、固定爪３８の先端爪部ｄが弾性変形して開き、スイッチ基板５０の通過を許容する。   The connector 51, the first switch 52, and the second switch 53 are mounted on the front surface of the switch board 50 from above at a predetermined interval. When the switch board 50 on which these components are mounted is inserted into the inside from the back opening of the switch fixing part 34, the side edge of the switch board 50 comes into contact with the front end claw part d of the fixing claw 38. When the switch board 50 is further pushed in, the front end claw portion d of the fixing claw 38 is elastically deformed and opened to allow the switch board 50 to pass through.

スイッチ基板５０が先端爪部ｄを乗り越えたところで、スイッチ基板５０はスイッチ固定部３４の角部に当接して、それ以上の押し込みが規制される。その一方で、固定爪３８がもとの状態に復帰し、スイッチ基板５０を挟持する。スイッチ固定部３４内にはスイッチ基板５０の上端縁と下端縁とが嵌り込む支え片ｅが一体に設けられていて、スイッチ基板５０の上下端部位置の移動が規制される。   When the switch board 50 gets over the tip claw part d, the switch board 50 comes into contact with the corner of the switch fixing part 34, and further pressing is restricted. On the other hand, the fixing claw 38 returns to the original state, and the switch board 50 is clamped. A support piece e into which the upper end edge and the lower end edge of the switch substrate 50 are fitted is integrally provided in the switch fixing portion 34, and movement of the upper and lower end portions of the switch substrate 50 is restricted.
