　（実施の形態１）
　図１は、本実施の形態における空気調和機の室内機の外観図、図２（ａ）は、室内機の前面パネルを取り付けた状態の正面図、図２（ｂ）は、室内機の前面パネルを取り外した状態の正面図、図３（ａ）は、室内機の停止時のＡＡ断面図、図３（ｂ）は、室内機の運転時のＡＡ断面図、である。なお、本実施の形態における空気調和機は、室内に設置される室内機１と、室外に設置される室外機（図示せず）とを冷媒配管および接続電線で接続することによって構成される。 (Embodiment 1)
FIG. 1 is an external view of an indoor unit of an air conditioner in the present embodiment, FIG. 2A is a front view of a state in which a front panel of the indoor unit is attached, and FIG. 2B is a front view of the indoor unit. FIG. 3A is a cross-sectional view taken along the line AA when the indoor unit is stopped, and FIG. 3B is a cross-sectional view taken along the line AA when the indoor unit is in operation. In addition, the air conditioner in this Embodiment is comprised by connecting the indoor unit 1 installed indoors, and the outdoor unit (not shown) installed outdoors with refrigerant | coolant piping and a connecting wire.
　図１から図３を用いて、室内機１の構成について説明する。本実施の形態における室内機１は、天面側から吸い込む天面吸い込み口２ａと、前面側から吸い込む前面吸い込み口２ｂとを有し、前面側の前面吸い込み口２ｂの前側を覆う前面パネル２を有している。室内機１の運転停止時には前面パネル２は閉じた状態となっているが、運転が開始されると前面パネル２が開いた状態となり、吸い込む風量を増加させる。 The configuration of the indoor unit 1 will be described with reference to FIGS. 1 to 3. The indoor unit 1 in the present embodiment has a front panel 2 that has a top suction port 2a that sucks in from the top side and a front suction port 2b that sucks in from the front side, and covers the front side of the front suction port 2b on the front side. Have. When the operation of the indoor unit 1 is stopped, the front panel 2 is in a closed state, but when the operation is started, the front panel 2 is in an open state, and the amount of air sucked is increased.
　また、室内機１には、室内へ送風する吹き出し口３を有し、上下に風向を変更する上下羽根３ａと、左右に風向を変更する左右羽根３ｂとを備える。また、室内機１の内部には略逆Ｖ字形状の室内熱交換器５と、室内へ送風する室内ファン６と、塵埃を捕集するエアフィルター７と、を備える。また、エアフィルター７はフィルター枠７ａに保持される。なお、エアフィルター枠７ａには、エアフィルター７を自動で掃除する自動掃除装置を搭載しているが、この説明については省略する。 Also, the indoor unit 1 has a blowout port 3 for blowing air into the room, and includes upper and lower blades 3a that change the wind direction up and down, and left and right blades 3b that change the wind direction left and right. The indoor unit 1 includes a substantially inverted V-shaped indoor heat exchanger 5, an indoor fan 6 that blows air into the room, and an air filter 7 that collects dust. The air filter 7 is held by the filter frame 7a. The air filter frame 7a is equipped with an automatic cleaning device that automatically cleans the air filter 7, but this description is omitted.
　そして、室内ファン６を駆動することによって風の流れを発生させ、天面吸い込み口２ａおよび前面吸い込み口２ｂから室内空気を吸い込み、室内熱交換器５で冷媒と室内空気とが熱交換する。その後、冷房であれば冷たくなった室内空気を、暖房であれば暖かくなった室内空気をそれぞれ室内へ送る。 Then, the indoor fan 6 is driven to generate a wind flow, the indoor air is sucked from the top suction port 2a and the front suction port 2b, and the indoor heat exchanger 5 exchanges heat between the refrigerant and the indoor air. Then, if it is cooling, the indoor air which became cold will be sent indoors, and if it will be heating, the indoor air which became warm will be sent indoors.
　このように構成された室内機において、天面吸い込み口２ａと前面吸い込み口２ｂと室内熱交換器５の前面で区画された箇所に電装ユニット８を配置している。このように電装ユニット８を配置することによって、天面吸い込み口２ａと前面吸い込み口２ｂと室内熱交換器５で区画されたデッドスペースを有効活用して電装ユニット８を配置することができる。これによって、室内熱交換器５の側部に電装ユニット８を配置せず、室内熱交換器５の横幅方向を長くすることができ、室内熱交換器５における熱交換性能を向上させることができる。 In the indoor unit configured in this way, the electrical unit 8 is arranged at a location partitioned by the top surface suction port 2a, the front surface suction port 2b, and the front surface of the indoor heat exchanger 5. By disposing the electrical unit 8 in this manner, the electrical unit 8 can be disposed by effectively utilizing the dead space defined by the top surface suction port 2a, the front surface suction port 2b, and the indoor heat exchanger 5. As a result, the electrical unit 8 is not arranged on the side of the indoor heat exchanger 5, the width direction of the indoor heat exchanger 5 can be lengthened, and the heat exchange performance in the indoor heat exchanger 5 can be improved. .
　また、電装ユニット８は電装部品が配置された基板を有しているため発熱するが、天面吸い込み口２ａおよび前面吸い込み口２ｂから吸い込まれる風によって電装ユニット８を冷却することができる。また、室内熱交換器５よりも上方に電装ユニット８を配置するので、電装ユニット８に室内熱交換器５で発生するドレン水が掛かってしまうことを抑制し、信頼性を向上させることができる。 Also, the electrical unit 8 generates heat because it has a substrate on which electrical components are arranged, but the electrical unit 8 can be cooled by the wind sucked from the top suction port 2a and the front suction port 2b. Moreover, since the electrical unit 8 is disposed above the indoor heat exchanger 5, it is possible to suppress the drain water generated in the indoor heat exchanger 5 from being applied to the electrical unit 8 and improve the reliability. .
　次に、電装ユニット８の構成について説明する。図４は、電装ユニット８の外観斜視図、図５は、電装ユニット８の分解斜視図である。また、図６は、電装ユニット８とフィルター枠７ａとの位置関係を示した図である。 Next, the configuration of the electrical unit 8 will be described. 4 is an external perspective view of the electrical unit 8, and FIG. 5 is an exploded perspective view of the electrical unit 8. FIG. 6 is a diagram showing the positional relationship between the electrical unit 8 and the filter frame 7a.
　図４～図６に示すように、電装ユニット８は、板金で形成された支持板８ａと、難燃性の樹脂で形成されたベース８ｂと、電装部品が配置された基板８ｃと、難燃性の樹脂で形成されたカバー８ｄと、板金で形成された板金カバー８ｅとに分解することができる。本実施の形態では、ベース８ｂとカバー８ｄで用いられている難燃性の樹脂として、ＡＢＳ樹脂を用いているが、これに限定されることはなく、その他の難燃性樹脂を用いても構わない。 As shown in FIGS. 4 to 6, the electrical unit 8 includes a support plate 8a formed of sheet metal, a base 8b formed of flame-retardant resin, a substrate 8c on which electrical components are disposed, and a flame retardant. It can be disassembled into a cover 8d formed of a conductive resin and a sheet metal cover 8e formed of sheet metal. In the present embodiment, the ABS resin is used as the flame retardant resin used in the base 8b and the cover 8d, but the present invention is not limited to this, and other flame retardant resins may be used. I do not care.
　また、基板８ｃ内の電装部品と室外機（図示せず）との電装部品とを結ぶ内外接続電線が接続される端子台８ｆは、電装ユニット８とは分割して側部に配置され、前面側から作業ができるように、内外接続電線が接続される接続部は正面方向を向いている。 Further, the terminal block 8f to which the internal / external connection electric wire connecting the electrical component in the substrate 8c and the electrical component of the outdoor unit (not shown) is connected to the front side is divided from the electrical unit 8 and is disposed on the side. In order to be able to work from the side, the connection part to which the inner and outer connection electric wires are connected faces the front direction.
　そして、支持板８ａは、フィルター枠７ａの両端で支持するように配置されており、かつ、支持板８ａを板金で形成しているので、輸送時などに発生する外力に対する電装ユニット８の変形を防ぐことができる。さらにはメンテナンス時に作業者が電装ユニット８に外力を掛けることがあっても、板金で形成された支持板８ａで支えているため、電装ユニット８とフィルター枠７ａとの距離が縮まることがなく、一定量の吸い込み風量を確実に確保することができる。なお、フィルター枠７ａと支持板８ａとの接続は、ネジで接続してもよいし、引っ掛けるようにして接続してもよい。 The support plate 8a is disposed so as to be supported at both ends of the filter frame 7a, and the support plate 8a is formed of a sheet metal, so that the electrical unit 8 can be deformed against an external force generated during transportation or the like. Can be prevented. Furthermore, even if an operator may apply an external force to the electrical unit 8 during maintenance, the distance between the electrical unit 8 and the filter frame 7a is not reduced because it is supported by the support plate 8a formed of sheet metal. A certain amount of suction air volume can be reliably secured. Note that the filter frame 7a and the support plate 8a may be connected by screws or may be hooked.
　また、本実施の形態では支持板８ａの右側に基板８ｃを配置するように電装ユニット８が形成されており、左側には開口部８ｇを設けている。支持板８ａをフィルター枠７ａの横幅方向全部にわたって配置するので風の流れを遮ってしまうことになる。そのため、本実施の形態では、右側に基板８ｃを配置し、左側に開口部８ｇを設けることによって開口部８ｇに風が通る通路を設けることで、通風抵抗を低減することができる。なお、基板８ｃの配置と開口部８ｇの配置は左右逆であっても、基板８ｃと開口部８ｇの配置を上下にしても問題は無い。 In the present embodiment, the electrical unit 8 is formed so that the substrate 8c is disposed on the right side of the support plate 8a, and an opening 8g is provided on the left side. Since the support plate 8a is disposed over the entire width of the filter frame 7a, the flow of wind is blocked. For this reason, in this embodiment, by providing the substrate 8c on the right side and providing the opening 8g on the left side to provide a passage through which air passes through the opening 8g, the ventilation resistance can be reduced. It should be noted that even if the arrangement of the substrate 8c and the arrangement of the opening 8g are opposite to each other, there is no problem even if the arrangement of the substrate 8c and the opening 8g is arranged up and down.
　さらに、本実施の形態では、板金カバー８ｅの両端部には樹脂製のカバー８ｈを設けており、樹脂製のカバー８ｈで板金カバー８ｅの両端部を覆う構成としている。このような構成とすることによって、板金カバー８ｅのエッジを保護する構成となり、さらに作業性を向上することができる。 Furthermore, in the present embodiment, a resin cover 8h is provided at both ends of the sheet metal cover 8e, and the both ends of the sheet metal cover 8e are covered with the resin cover 8h. With this configuration, the edge of the sheet metal cover 8e is protected, and workability can be further improved.
　図７は、ＢＢ断面図であり、図８は、ベース８ｂとカバー８ｄとの突合せ部の要部拡大略図である。図７、図８に示すようにベース８ｂの周囲に沿って溝形状９が形成されており、溝形状９は内側の側壁９ａと、外側の側壁９ｂとで形成される。 FIG. 7 is a cross-sectional view taken along the line BB, and FIG. As shown in FIGS. 7 and 8, a groove shape 9 is formed along the periphery of the base 8b, and the groove shape 9 is formed by an inner side wall 9a and an outer side wall 9b.
　一方、カバー８ｄには溝形状９に嵌め合わせることができるように、溝形状９と対向する位置に凸形状１０を設けている。そして、溝形状９に凸形状１０が収まり、ベース８ｂにカバー８ｄが嵌め合わされる。このとき隙間無く嵌め合わされることが望ましいが、ものづくり上の誤差で隙間１１があいてしまう。 On the other hand, the cover 8d is provided with a convex shape 10 at a position facing the groove shape 9 so that the cover 8d can be fitted into the groove shape 9. Then, the convex shape 10 is accommodated in the groove shape 9, and the cover 8d is fitted into the base 8b. At this time, it is desirable to fit with no gap, but there is a gap 11 due to a manufacturing error.
　そこで、本実施の形態では、ベース８ｂとカバー８ｄとの嵌め合わせ部において難燃性部材１２を配置している。本実施の形態では、難燃性部材１２にＥＰＴシールを用いており、軟性、すなわち弾性力を有しているため、ベース８ｂとカバー８ｄとが嵌め合わさるときに力が掛かり隙間を埋めるように難燃性部材１２が変形する。 Therefore, in the present embodiment, the flame retardant member 12 is disposed in the fitting portion between the base 8b and the cover 8d. In the present embodiment, an EPT seal is used for the flame retardant member 12 and is soft, that is, has an elastic force. Therefore, when the base 8b and the cover 8d are fitted together, a force is applied to fill the gap. The flame retardant member 12 is deformed.
　このように、ベース８ｂとカバー８ｄとの間に弾性力を有する難燃性部材１２を用いることで、電装ユニット８の内部と外部との隙間を埋めることができるため、異物の侵入を防ぐことができる。さらに、ベース８ｂとカバー８ｄとの間の部材１２が難燃性であるため、電装ユニットで発火した場合の外部への延焼を防ぐことができる。 As described above, by using the flame retardant member 12 having elasticity between the base 8b and the cover 8d, the gap between the inside and the outside of the electrical unit 8 can be filled, so that foreign matter can be prevented from entering. Can do. Furthermore, since the member 12 between the base 8b and the cover 8d is flame retardant, it is possible to prevent the spread of fire to the outside when ignited by the electrical unit.
　また、溝形状９を形成する内側の側壁９ａの高さＨ１を、外側の側壁９ｂの高さＨ２よりも高くしている。例えば、異物が何らかの理由で側壁９ｂを超えて溝形状９に侵入したとしても、さらに高い側壁９ａがあるために、電装ユニット８の内部への異物侵入を防ぐことができる。 Further, the height H1 of the inner side wall 9a forming the groove shape 9 is set higher than the height H2 of the outer side wall 9b. For example, even if a foreign matter enters the groove shape 9 beyond the side wall 9b for some reason, the higher side wall 9a is present, so that foreign matter can be prevented from entering the electrical unit 8.
