Description

本発明は、壁掛け用の室内機を複数用いたマルチ型の空気調和機に関する。   The present invention relates to a multi-type air conditioner using a plurality of wall-mounted indoor units.

従来の壁掛け用の室内機では、熱交換率を高くするために、筐体内の幅方向の全体に亘って室内熱交換器を配置している。また、熱交換器機の断面形状は、送風ファンの前後及び上側を覆うべく、略Ｊ字形状（詳細には、逆Ｊ字形状）に形成されている（特許文献１及び特許文献２参照）。これにより、上側に位置する吸込口から吸い込まれた室内空気は、室内熱交換器を通過して、下側に位置する送風口から熱交換後の空気が送風されるようになる。   In a conventional wall-mounted indoor unit, an indoor heat exchanger is arranged over the entire width in the housing in order to increase the heat exchange rate. Moreover, the cross-sectional shape of the heat exchanger is formed in a substantially J shape (specifically, an inverted J shape) so as to cover the front and back and the upper side of the blower fan (see Patent Document 1 and Patent Document 2). Thereby, the indoor air sucked from the suction port located on the upper side passes through the indoor heat exchanger, and the air after heat exchange is blown from the blower port located on the lower side.

一方、壁掛け用の複数台の室内機と、室外機とで構成されるいわゆるマルチ型の空気調和装置では、この各室内機の筐体内に冷媒の流量を調整するための電動膨張弁を収納し、各室内機で冷暖房運転を個々に操作し得るようにしている。
特開２００５−１６８３０号公報 特開２００５−２３３４８４号公報 On the other hand, in a so-called multi-type air conditioner composed of a plurality of wall-mounted indoor units and an outdoor unit, an electric expansion valve for adjusting the flow rate of the refrigerant is accommodated in the casing of each indoor unit. In each indoor unit, the air conditioning operation can be individually operated.

しかしながら、室内機の筐体内に電動膨張弁を取り付けるためには、室内機の内容積を広げなければならず、通常の室内機と比べて外形寸法が大きくなってしまう。
また、電動膨張弁を取り付ける場合には、異物を除去するストレーナーや、オリフィスを設けなければならず、運転時の運転音が通常の室内機と比べて大きくなってしまう。 However, in order to mount the electric expansion valve in the housing of the indoor unit, the internal volume of the indoor unit must be expanded, and the external dimensions are larger than that of a normal indoor unit.
In addition, when an electric expansion valve is attached, a strainer for removing foreign matter and an orifice must be provided, and the operation noise during operation becomes larger than that of a normal indoor unit.

本発明は、上述した事情に鑑みてなされたものであり、電動膨張弁を内蔵しない通常の室内機と比較して、室内機の形状を大きくすることがなく、かつ電動膨張弁を内蔵しない通常の室内機と比較して、運転時の運転音を略同等にすることができる空気調和機を提供することを目的とする。   The present invention has been made in view of the above-described circumstances, and does not increase the shape of the indoor unit and does not have a built-in electric expansion valve compared to a normal indoor unit that does not have a built-in electric expansion valve. It aims at providing the air conditioner which can make the driving | running | working sound at the time of driving | running | working substantially equivalent compared with this indoor unit.

本発明では、室内機の筐体内に、送風ファンの前後及び上方を覆う熱交換器と、電動膨張弁とを備えた空気調和機において、前記熱交換器の左端部又は右端部のいずれかの一部であって、前記送風ファンの後方を覆う部分に切り欠き部を設け、この切り欠き部に前記電動膨張弁を配設したことを特徴とする。
この構成によれば、熱交換器に必要な効率を確保しつつ、電動膨張弁を室内機に配置することができる。 In this invention, in the air conditioner provided with the heat exchanger which covers the front and back and the upper part of a ventilation fan in the housing | casing of an indoor unit, and an electric expansion valve, either the left end part or the right end part of the said heat exchanger A notch part is provided in a part covering the rear of the blower fan, and the electric expansion valve is disposed in the notch part.
According to this configuration, the electric expansion valve can be arranged in the indoor unit while ensuring the efficiency required for the heat exchanger.

また、前記室内機が前記熱交換器の外形状に沿って着脱可能なフィルターを備え、前記切り欠き部に前記電磁膨張弁の外方を覆うカバー部材を設けることもできる。
この構成によれば、フィルターを電動膨張弁に引っ掛けることがなく、容易にフィルターを着脱することができる。 The indoor unit may include a filter that is detachable along the outer shape of the heat exchanger, and a cover member that covers the outside of the electromagnetic expansion valve may be provided in the notch.
According to this configuration, the filter can be easily attached and detached without hooking the filter on the electric expansion valve.

さらに、前記切り欠き部に、前記電磁膨張弁に接続されるストレーナーを配置してもよい。
この構成によれば、大きな運転音を発生するストレーナーが裏側にあるので、室内側から音が聞こえ難くすることができる。さらには、カバー部材によって運転音を低減させることができる。 Furthermore, you may arrange | position the strainer connected to the said electromagnetic expansion valve in the said notch part.
According to this configuration, since the strainer that generates a loud driving sound is on the back side, it is difficult to hear the sound from the indoor side. Furthermore, driving noise can be reduced by the cover member.

また、前記切り欠き部を設けた端部側に、電装箱を配置してもよい。
この構成によれば、電磁膨張弁と接続される配線を短くすることができる。 Moreover, you may arrange | position an electrical equipment box in the edge part side which provided the said notch part.
According to this configuration, the wiring connected to the electromagnetic expansion valve can be shortened.

さらに、前記室内機の前記切り欠き部を設けた端部側から、室外機に接続される冷媒配管を延出させてもよい。
この構成によれば、電磁膨張弁と接続される冷媒配管を短くすることができる。 Furthermore, you may extend the refrigerant | coolant piping connected to an outdoor unit from the edge part side which provided the said notch part of the said indoor unit.
According to this configuration, the refrigerant pipe connected to the electromagnetic expansion valve can be shortened.

本発明によれば、室内機の筐体内に、送風ファンの前後及び上方を覆う熱交換器と、電動膨張弁とを備えた空気調和機において、前記熱交換器の左端部又は右端部のいずれかの一部であって、前記送風ファンの後方を覆う部分に切り欠き部を設け、この切り欠き部に前記電動膨張弁を配設しているので、熱交換器に必要な効率を確保しつつ、電動膨張弁を配置することができる。そのため、室内機の内部に電動膨張弁を配置するスペースを別途確保する必要がなくなる。また、室内機の前部を覆う前ケースを外したときに、電動膨張弁が見えない位置にあるため、前ケースを外しても見た目がよい。さらに、通常の室内機と同じ大きさにすることができるので、製造時における金型や使用部品類を共通化することができる。
また、熱交換器の後方部分に切り欠き部を設けて、この切り欠き部に電動膨張弁を配置しているので、室内側から電動膨張弁までの距離をできるだけ遠ざけることができる。その結果、室内側で電動膨張弁の運転音が小さく聞こえる（消音される）ようになるので、室内の居住性を良好に維持することができる。 According to the present invention, in an air conditioner provided with a heat exchanger that covers the front and rear and the top of the blower fan and an electric expansion valve in the casing of the indoor unit, either the left end portion or the right end portion of the heat exchanger is provided. A notch is provided in a part covering the rear of the blower fan, and the electric expansion valve is disposed in the notch, so that the efficiency required for the heat exchanger is ensured. However, an electric expansion valve can be arranged. Therefore, it is not necessary to separately secure a space for arranging the electric expansion valve inside the indoor unit. Further, when the front case that covers the front part of the indoor unit is removed, the electric expansion valve is in a position where it cannot be seen. Furthermore, since it can be made the same size as a normal indoor unit, it is possible to share a mold and used parts at the time of manufacture.
Moreover, since the notch part is provided in the rear part of the heat exchanger and the electric expansion valve is disposed in the notch part, the distance from the indoor side to the electric expansion valve can be as far as possible. As a result, since the operation sound of the electric expansion valve can be heard (muffled) on the indoor side, the comfort in the room can be maintained well.

また、前記室内機が前記熱交換器の外形状に沿って着脱可能なフィルターを備え、前記切り欠き部に前記電磁膨張弁の外方を覆うカバー部材を設けているので、フィルターを電動膨張弁に引っ掛けることがなく、フィルターを容易に着脱することができる。   In addition, since the indoor unit includes a filter that can be attached and detached along the outer shape of the heat exchanger, and the cover member that covers the outside of the electromagnetic expansion valve is provided at the notch, the filter is electrically driven by the expansion valve. The filter can be easily attached and detached without being hooked on.

さらに、前記切り欠き部に、前記電磁膨張弁に接続されるストレーナーを配置しているので、大きな運転音を発生するストレーナーが裏側にあるので、室内側から音が聞こえ難くすることができる。さらには、カバー部材によって運転音を低減させることができる。その結果、室内の居住性を良好に維持することができる。   Furthermore, since the strainer connected to the electromagnetic expansion valve is arranged in the notch portion, the strainer that generates a loud driving sound is on the back side, so that it is difficult to hear the sound from the indoor side. Furthermore, driving noise can be reduced by the cover member. As a result, the indoor habitability can be maintained well.

さらにまた、前記切り欠き部を設けた端部側に、電装箱を配置し、前記室内機の前記切り欠き部を設けた端部側から、室外機に接続される冷媒配管を延出させているので、配線及び冷媒配管を短くすることができ、引き回しが容易になる。   Furthermore, an electrical box is disposed on the end portion side where the cutout portion is provided, and a refrigerant pipe connected to the outdoor unit is extended from the end portion side where the cutout portion of the indoor unit is provided. Therefore, the wiring and the refrigerant piping can be shortened, and the routing becomes easy.

以下、本発明の実施の形態に係る空気調和機について、図面を参照しながら説明する。図１は、マルチ型の空気調和機の概要図である。
空気調和機１は、室内の壁に掛けられる壁掛け用の室内機２（本実施の形態では、２台の室内機２ａ、２ｂ）と室外に設置される室外機３とを備え、それぞれが２本の冷媒管４（液管４Ａ、ガス管４Ｂ）で接続されている。また、それぞれの室内機２ａ、２ｂは、ワイヤレスリモコン装置５によって遠隔操作可能になっている。
なお、室内機２を２台としたのは一例であり、３台以上の室内機２ａ、２ｂ、…が冷媒管４を介して室外機３に接続されていてもよい。 Hereinafter, an air conditioner according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a multi-type air conditioner.

なお、室内機２ａと室内機２ｂとは、それぞれ同じ構造を有しているため、以下、室内機２ａについて説明し、室内機２ｂについての説明は省略する。 FIG. 2 is a cross-sectional view of the indoor unit 2a viewed from the side, with the left side being the wall side and the right side being the indoor side (front side). 3 is an exploded perspective view of the indoor unit 2, and FIG. 4 is an exploded perspective view of the front portion of the indoor unit 2.
Since the indoor unit 2a and the indoor unit 2b have the same structure, the indoor unit 2a will be described below, and the description of the indoor unit 2b will be omitted.

室内機２ａの外形状を形成する筐体は、図２に示すように、前面側の前ケース部２Ａと、後面側の後ケース部２Ｂと、前ケース部２Ａの下側に位置するルーバー部２Ｃとで構成されている。この前ケース部２Ａは、その前側に前面パネル２Ｄが取り付けられており、上面部に吸込口２ｆが設けられ、ルーバー部２Ｃには、吹出口９が設けられている。また、後ケース部２Ｂの後側には、室内の壁に取り付けるための、据付け枠体１４（図３参照）が設けられている。   As shown in FIG. 2, the casing forming the outer shape of the indoor unit 2a includes a front case part 2A on the front side, a rear case part 2B on the rear side, and a louver part located below the front case part 2A. 2C. The front case portion 2A has a front panel 2D attached to the front side thereof, a suction port 2f provided in the upper surface portion, and a blowout port 9 provided in the louver portion 2C. Further, an installation frame body 14 (see FIG. 3) is provided on the rear side of the rear case portion 2B to be attached to the indoor wall.

この前ケース部２Ａと後ケース部２Ｂとに囲まれた部分の内方には、図２に示すように、室内熱交換器１１と、この室内熱交換器１１の下側に位置する送風ファン１２と、室内熱交換器１１の下側を覆い、室内熱交換器１１から流下するドレン水を貯留し排出するドレンパン６と、前ケース部２Ａと室内熱交換器１１との間に着脱可能に配置され、吸込まれた室内側空気内の比較的大きな塵や埃を除塵するエアフィルター７と、後ケース部２Ｂの右側端部に取り付けられ、後述する電動膨張弁１６等を制御する電装箱１３（図３参照）とが設けられている。   As shown in FIG. 2, an indoor heat exchanger 11 and a blower fan located below the indoor heat exchanger 11 are disposed in the inner portion of the portion surrounded by the front case portion 2A and the rear case portion 2B. 12, a drain pan 6 that covers the lower side of the indoor heat exchanger 11 and stores and discharges drain water flowing down from the indoor heat exchanger 11, and is removable between the front case portion 2A and the indoor heat exchanger 11. An air filter 7 that is arranged and removes relatively large dust in the indoor air that has been sucked in, and an electrical box 13 that is attached to the right end of the rear case portion 2B and controls an electric expansion valve 16 and the like to be described later. (See FIG. 3).

室内熱交換器１１は、室内の空気を加熱／冷却（調温）するものであり、その配管内を冷媒が通過することにより、冷房／ドライ運転時に蒸発器として作用し、冷却器として機能する。また、暖房運転時には、凝縮器として作用し、加熱器として機能するものである。この室内熱交換器１１は、図２に示すように、その断面形状が略Ｊ字形状（詳細には、Ｊ字形状の上下を逆さにした形状）をなしており、送風ファン１２の前後及び上方を覆うようになっている。これにより、前ケース部２Ａの上方から吸い込まれる室内側空気Ｗ１が、この室内熱交換器１１を通過するように配置されている。
また、この室内熱交換器１１は、図３に示すように、室内機２の幅方向の全体（詳細には、前ケース部２Ａの左側端部から電装箱１３まで）に亘って延在する態様で配置されている。なお、室内熱交換器１１の詳細については、後述する。 The indoor heat exchanger 11 heats / cools (controls temperature) the air in the room. When the refrigerant passes through the piping, the indoor heat exchanger 11 functions as an evaporator during cooling / dry operation and functions as a cooler. . Further, during heating operation, it acts as a condenser and functions as a heater. As shown in FIG. 2, the indoor heat exchanger 11 has a substantially J-shaped cross section (specifically, a shape in which the J shape is turned upside down). It covers the top. Thereby, the indoor side air W <b> 1 sucked from above the front case portion 2 </ b> A is disposed so as to pass through the indoor heat exchanger 11.
Further, as shown in FIG. 3, the indoor heat exchanger 11 extends over the entire width of the indoor unit 2 (specifically, from the left end of the front case portion 2A to the electrical box 13). Arranged in a manner. The details of the indoor heat exchanger 11 will be described later.

送風ファン１２は、吸込口２ｆから室内側空気Ｗ１（図２参照）が室内熱交換器１１を通過するように吸込み、吹出口９から加熱／冷却後の空気Ｗ２（図２参照）を再び室内に循環させるためのものである。この送風ファン１２は、図３に示すように、室内熱交換器１１と同様に、室内機２の幅方向の全体（詳細には、前ケース部２Ａの左側端部から電装箱１３まで）に亘って延在する態様で配置されている。また、この送風ファン１２は、側部に配置された送風ファンモータ１２Ａ（例えば、クロスフローファン）によって駆動されるようになっている。   The blower fan 12 sucks the indoor air W1 (see FIG. 2) from the suction port 2f so as to pass through the indoor heat exchanger 11, and the heated / cooled air W2 (see FIG. 2) from the blowout port 9 again. It is for circulation. As shown in FIG. 3, the blower fan 12 is disposed in the entire width direction of the indoor unit 2 (specifically, from the left end of the front case portion 2 </ b> A to the electrical equipment box 13), like the indoor heat exchanger 11. It arrange | positions in the aspect extended over. The blower fan 12 is driven by a blower fan motor 12A (for example, a cross flow fan) disposed on the side.

また、エアフィルター７と室内熱交換器１１との間であって、空気調和機１の前側部分には、図２に示すように、空気清浄フィルター８が設けられている。この空気清浄フィルター８は、エアフィルター７を通過した室内空気内の比較的細かい塵や埃を除塵するためのものである。
さらに、吹出口９には、この吹出口９から吹出す温風／冷風の上下風向を制御するフラップ９Ａと、この吹出口９から吹出す温風／冷風の左右風向を制御する複数の縦羽根１０が取り付けられている。このフラップ９Ａには、その角度を調整する駆動用モータが取り付けられ、ワイヤレスリモコン装置５の操作によりフラップ９Ａが回動自在に制御されるようになっている。 Further, as shown in FIG. 2, an air purification filter 8 is provided between the air filter 7 and the indoor heat exchanger 11 and on the front side portion of the air conditioner 1. The air cleaning filter 8 is for removing relatively fine dust and dust in the indoor air that has passed through the air filter 7.
Further, the air outlet 9 has a flap 9A for controlling the up / down direction of hot air / cold air blown from the air outlet 9 and a plurality of vertical blades for controlling the left / right air directions of the hot air / cold air blown out from the air outlet 9. 10 is attached. A driving motor for adjusting the angle of the flap 9A is attached to the flap 9A, and the flap 9A is rotatably controlled by the operation of the wireless remote controller 5.

図５は、本実施の形態に係る空気調和機１の冷媒回路図を示す。

室内熱交換器１１は、逆Ｊ字形状の頂上部で、前側に位置する親熱交換器１１Ａと、後側に位置する子熱交換器１１Ｂとが分離又は組み付け可能に構成されている。また、親熱交換器１１Ａの右側端部には、液管４Ａと、ガス管４Ｂと、ドレンパン６からドレン水を排出するドレン配管２８が組み付けられるようになっている。 FIG. 6 shows an exploded perspective view of the indoor heat exchanger 11 attached to the indoor units 2a and 2b. In FIG. 6, the front side (indoor side) is a diagonally lower left side. Moreover, FIG.7 and FIG.8 is the perspective view which looked at the indoor heat exchanger 11 from diagonally left back, Comprising: The state which attached the electric expansion valve 16 is shown.
The indoor heat exchanger 11 has an inverted J-shaped top and is configured such that a parent heat exchanger 11A located on the front side and a child heat exchanger 11B located on the rear side can be separated or assembled. Further, a liquid pipe 4A, a gas pipe 4B, and a drain pipe 28 for discharging drain water from the drain pan 6 are assembled to the right end of the parent heat exchanger 11A.

この子熱交換器１１Ｂの長さＬ２は、図６に示すように、親熱交換器１１Ａの幅方向の長さＬ１と比較して、短く形成されている。より詳細には、子熱交換器１１Ｂと親熱交換器１１Ａとの左端部が一致するように組み付けた状態で、子熱交換器１１Ｂの右端部が切り欠かれたように（以下、切り欠き部２９という。図７及び図８参照）なっている。この切り欠き部２９は、図３に示すように、電装箱１３が配置される側に形成されている。   The length L2 of the child heat exchanger 11B is formed shorter than the length L1 in the width direction of the parent heat exchanger 11A as shown in FIG. More specifically, in a state where the left end portions of the child heat exchanger 11B and the parent heat exchanger 11A are assembled so as to coincide with each other, the right end portion of the child heat exchanger 11B is cut out (hereinafter referred to as a notch portion). 29. See FIG. 7 and FIG. As shown in FIG. 3, the notch 29 is formed on the side where the electrical box 13 is disposed.

この切り欠き部２９には、図７及び図８に示すように、電動膨張弁１６が取り付けられている。また、液管４Ａとガス管４Ｂとは、フレキシブルなパイプ３０内に内包して室外機３まで配管されるており、この切り欠き部２９から、このパイプ３０が延びている。さらに、この切り欠き部２９には、ストレーナー１７を配置することもできる。
このように取り付けられた電動膨張弁１６は、図２に２点差線で示すように、室内機２ａの側部から見て、親熱交換器１１Ａの後方であって、室内機２ａの壁側上部に位置することになる。 As shown in FIGS. 7 and 8, the electric expansion valve 16 is attached to the notch 29. The liquid pipe 4 </ b> A and the gas pipe 4 </ b> B are included in a flexible pipe 30 and are piped to the outdoor unit 3, and the pipe 30 extends from the notch 29. Furthermore, the strainer 17 can be disposed in the notch 29.
The electric expansion valve 16 attached in this way is, as shown by a two-dotted line in FIG. 2, viewed from the side of the indoor unit 2a, behind the parent heat exchanger 11A, and on the wall side of the indoor unit 2a. Will be located.

また、電動膨張弁１６の外周には、図８に示すように、カバー部材３１が取り付けられている。また、親熱交換器１１Ａの右側側部（図８では左側となる）も、カバー部材３２で覆われるようになる。
このカバー部材３１は、図８に示すように、１枚の鋼板を上下に折り曲げたものであり、電動膨張弁１６の幅方向の全体を覆っている。また、カバー部材３１の上部には、親熱交換器１１Ａの表面と段差ができないように取り付けられる案内面部３１ａが形成されている。さらに、このカバー部材３１が取り付けられた後、図３に示す遮音部材３３ａ、３３ｂ、３３ｃ、３３ｄが親熱交換器１１Ａの右側側面、及び電装箱１３の前面を覆うように取り付けられる。 A cover member 31 is attached to the outer periphery of the electric expansion valve 16 as shown in FIG. Further, the right side portion (the left side in FIG. 8) of the parent heat exchanger 11 </ b> A is also covered with the cover member 32.
As shown in FIG. 8, the cover member 31 is formed by bending a single steel plate up and down and covers the entire width direction of the electric expansion valve 16. In addition, a guide surface portion 31a is formed on the upper portion of the cover member 31 so as not to be stepped from the surface of the parent heat exchanger 11A. Further, after the cover member 31 is attached, the sound insulation members 33a, 33b, 33c, and 33d shown in FIG. 3 are attached so as to cover the right side surface of the parent heat exchanger 11A and the front surface of the electrical box 13.

この案内面部３１ａは、エアフィルター７を着脱する際に、このエアフィルター７を案内するためのものである。より詳細には、エアフィルター７の取り付けは、図４に示すように、前面パネル２Ｄを取り外し、室内機２ａの奥行き方向に屈曲するエアフィルター７の上部７ａを、前ケース部２Ａの幅方向に長い長孔２ｅに挿入することにより行われる。このとき、エアフィルター７の上部７ａは、室内熱交換器１１の上部の形状に案内され、室内機２ａの奥側まで入り込むことになる。一方、切り欠き部２９では、子熱交換器１１Ｂが切り欠かれているため、カバー部材３１の案内面部３１ａがエアフィルター７の上部７ａを案内することになる。   The guide surface portion 31a is for guiding the air filter 7 when the air filter 7 is attached or detached. More specifically, as shown in FIG. 4, the air filter 7 is attached by removing the front panel 2D and placing the upper portion 7a of the air filter 7 bent in the depth direction of the indoor unit 2a in the width direction of the front case portion 2A. This is done by inserting it into the long long hole 2e. At this time, the upper part 7a of the air filter 7 is guided to the shape of the upper part of the indoor heat exchanger 11, and enters the back side of the indoor unit 2a. On the other hand, in the notch 29, since the child heat exchanger 11B is notched, the guide surface 31a of the cover member 31 guides the upper part 7a of the air filter 7.

本発明の実施の形態に係る空気調和機１では、室内熱交換器１１の子熱交換器１１Ｂの部分に切り欠き部２９を形成し、この切り欠き部２９に電動膨張弁１６を配置しているので、室内熱交換器１１に必要な効率を確保しつつ、電動膨張弁１６を配置することができる。そのため、室内機２ａ、２ｂの内部に電動膨張弁１６を配置するスペースを別途確保する必要がなくなる。また、室内機２ａ、２ｂの前部を覆う前ケース部２Ａまたは前面パネル２Ｄを外したときに、電動膨張弁１６が見えない位置にあるため、前ケース部２Ａまたは前面パネル２Ｄを外しても見た目がよい。さらに、電動膨張弁１６を内蔵しない通常の室内機と同じ大きさにすることができるので、製造時における前ケース部２Ａや後ケース部２Ｂなどの金型や使用部品類を共通化することができる。
また、室内機２ａ、２ｂの側部断面（図２参照）において、室内機２ａ、２ｂの壁側上部に電動膨張弁１６が配置されることになるので、室内側から電動膨張弁１６までの距離をできるだけ遠ざけるようにすることができる。その結果、室内側での電動膨張弁１６の運転音が小さく聞こえる（消音される）ようになるので、室内の居住性を良好に維持することができる。 In the air conditioner 1 according to the embodiment of the present invention, a notch 29 is formed in the portion of the child heat exchanger 11B of the indoor heat exchanger 11, and the electric expansion valve 16 is disposed in the notch 29. Therefore, the electric expansion valve 16 can be disposed while ensuring the efficiency required for the indoor heat exchanger 11. Therefore, it is not necessary to separately secure a space for arranging the electric expansion valve 16 inside the indoor units 2a and 2b. Further, when the front case 2A or the front panel 2D covering the front of the indoor units 2a and 2b is removed, the electric expansion valve 16 is in a position where it cannot be seen, so that even if the front case 2A or the front panel 2D is removed. It looks good. Furthermore, since it can be made the same size as a normal indoor unit that does not incorporate the electric expansion valve 16, it is possible to share molds and parts used such as the front case portion 2A and the rear case portion 2B at the time of manufacture. it can.
Moreover, in the side section (refer FIG. 2) of indoor unit 2a, 2b, since the electric expansion valve 16 will be arrange | positioned in the wall side upper part of indoor unit 2a, 2b, from the indoor side to the electric expansion valve 16 The distance can be kept as far as possible. As a result, since the operation sound of the electric expansion valve 16 on the indoor side can be heard (mute), the comfort in the room can be maintained well.

また、切り欠き部２９に、電動膨張弁１６の外方を覆うカバー部材３１を設けているので、エアフィルター７の着脱時に、このカバー部材３１の案内面部３１ａによってエアフィルター７の上部７ａを室内機２ａ、２ｂの奥側へ案内することができる。その結果、エアフィルター７の上部７ａが電動膨張弁１６に引っ掛かることなく、容易に着脱することができる。
他方、このカバー部材３１は、電動膨張弁１６を覆うことにより、電動膨張弁１６の運転音を遮蔽する役割を果たしている。これにより、さらに電動膨張弁１６の運転音を小さくすることができ、室内の居住性を良好にすることができる。 Further, since the cover member 31 that covers the outside of the electric expansion valve 16 is provided in the notch portion 29, when the air filter 7 is attached or detached, the upper surface 7a of the air filter 7 is placed indoors by the guide surface portion 31a of the cover member 31. It can guide to the back side of machine 2a, 2b. As a result, the upper part 7 a of the air filter 7 can be easily attached and detached without being caught by the electric expansion valve 16.
On the other hand, the cover member 31 serves to shield the operation sound of the electric expansion valve 16 by covering the electric expansion valve 16. Thereby, the driving sound of the electric expansion valve 16 can be further reduced, and the comfort in the room can be improved.

さらに、ストレーナー１７を電動膨張弁１６と共に配置することで、ストレーナー１７の音も消音されるようになる。そのため、室内の居住性を良好に維持することができる。   Further, by arranging the strainer 17 together with the electric expansion valve 16, the sound of the strainer 17 is also silenced. For this reason, it is possible to maintain good indoor comfortability.

さらにまた、切り欠き部２９を電装箱１３が配置される側に形成しているので、電動膨張弁１６と電装箱１３との距離を短くすることができる。そのため、電動膨張弁１６と電装箱１３との配線を短くすることができ、材料費を低減することができると共に、配線作業を容易にすることができる。   Furthermore, since the notch 29 is formed on the side where the electrical box 13 is disposed, the distance between the electric expansion valve 16 and the electrical box 13 can be shortened. Therefore, the wiring between the electric expansion valve 16 and the electrical box 13 can be shortened, the material cost can be reduced, and the wiring work can be facilitated.

また、液管４Ａとガス管４Ｂとを内包するパイプ３０が、切り欠き部２９から延在するようにしたので、液管４Ａとガス管４Ｂとを短くすることができる。そのため、材料費を低減することができると共に、配管作業を容易にすることができる。   Moreover, since the pipe 30 including the liquid pipe 4A and the gas pipe 4B extends from the notch 29, the liquid pipe 4A and the gas pipe 4B can be shortened. Therefore, material costs can be reduced and piping work can be facilitated.

以上、本発明を実施するための最良の形態について述べたが、本発明は既述の実施形態に限定されるものではなく、本発明の技術思想に基づいて各種の変形および変更が可能である。
本実施の形態では、電装箱１３を室内機２ａ、２ｂの右側端部に配置し、その近傍に切り欠き部２９を形成しているが、左右を逆にして入れ替えた構造であっても、本実施の形態と同様な作用・効果を得ることができる。 The best mode for carrying out the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. .
In the present embodiment, the electrical box 13 is arranged at the right end of the indoor units 2a and 2b, and the notch 29 is formed in the vicinity thereof, but even if the structure is replaced with the left and right reversed, The same actions and effects as in the present embodiment can be obtained.

また、カバー部材３１は、本実施の形態では鋼板製にしたが、遮音効果の高い材料、又は、エアフィルター７の案内性能（摩擦、摩耗性能）に問題がなければ、樹脂成型品であってもかまわない。   Further, the cover member 31 is made of a steel plate in the present embodiment. However, if there is no problem in the material having a high sound insulation effect or the guide performance (friction and wear performance) of the air filter 7, the cover member 31 is a resin molded product.
