Description

空気調和機の室内機Air conditioner indoor unit
　本発明の一態様は、キャビネットの構造に特徴を有する空気調和機の室内機に関する。本願は、２０１８年２月２７日に、日本に出願された特願２０１８－０３３６５９号に基づき優先権を主張し、その内容をここに援用する。 One embodiment of the present invention relates to an indoor unit of an air conditioner characterized by a cabinet structure. The present application claims priority based on Japanese Patent Application No. 2018-033659 filed in Japan on February 27, 2018, the contents of which are incorporated herein by reference.
　従来の空気調和機の室内機（以下、単に室内機と称する）は、能力に応じてキャビネットの長手方向の寸法が異なる。例えば、一部の室内機は、空調機能等の高機能化のために、シロッコファンからなる送風機を複数備えている。風量を多くするには、このような送風機の数を増やして室内機の長手方向に並べて配置することが必要となるため、キャビネットの長手方向の寸法が長くなる。 Conventional air conditioner indoor units (hereinafter simply referred to as indoor units) have different dimensions in the longitudinal direction of the cabinet depending on their capabilities. For example, some indoor units are provided with a plurality of blowers made of sirocco fans in order to enhance the functions such as the air conditioning function. In order to increase the air volume, it is necessary to increase the number of such fans and arrange them in the longitudinal direction of the indoor unit, so that the dimension in the longitudinal direction of the cabinet becomes long.
　能力に応じて異なる長さのキャビネットを作製するには、寸法の異なるキャビネットに応じた金型を用意する必要がある。 ¡In order to create cabinets with different lengths according to capacity, it is necessary to prepare dies for cabinets with different dimensions.
　このような不都合に対し、特許文献１には、キャビネット部分を左右の端部と、中央ケーシング部とに３分割された構造として、左右の端部を射出成形によって成形するとともに、中央ケーシング部を押出成形によって成形することが開示されている。これにより、室内機の設計寸法に適合する寸法を有する中央ケーシング部を用いることで、別機種の室内機に対応でき、また、寸法の異なる金型を新たに用意する必要がなくなる。 For such inconvenience, Patent Document 1 discloses that the cabinet part is divided into a left and right end part and a central casing part, and the left and right end parts are formed by injection molding. It is disclosed to form by extrusion. As a result, by using the central casing portion having dimensions that match the design dimensions of the indoor unit, it is possible to deal with different types of indoor units, and there is no need to newly prepare dies having different dimensions.
特許３２０５１５１号Patent 3205151
　しかしながら、中央ケーシング部が、押出成形によって成形することが不可能な一定でない断面形状を有する場合、金型を用いて中央ケーシング部を作製せざるを得ない。このため、中央ケーシング部の寸法に応じた金型を用意しなければならない。 However, when the central casing portion has a non-constant cross-sectional shape that cannot be formed by extrusion molding, the central casing portion must be manufactured using a mold. For this reason, a mold corresponding to the dimension of the central casing portion must be prepared.
　また、普及機種の中央ケーシングよりも長尺の中央ケーシング部を用いる機種では、室内機を組み立てる前に当該中央ケーシング部を保管するための特殊な箱を用意する必要がある。また、特殊な箱を用いて保管することに伴い、保管場所、輸送方法等も見直す必要もある。 Also, in a model using a central casing part longer than the central casing of a popular model, it is necessary to prepare a special box for storing the central casing part before assembling the indoor unit. In addition, with storage using special boxes, it is also necessary to review storage locations and transportation methods.
　本発明の一態様は、中間部分を１種類の金型を用いて作製することが可能な分割構造のキャビネットによって室内機を構成することを目的とする。 An object of one embodiment of the present invention is to configure an indoor unit with a cabinet having a divided structure in which an intermediate portion can be manufactured using one type of mold.
　上記の課題を解決するために、本発明の一態様に係る空気調和機の室内機は、左端部、右端部および前記左端部と前記右端部との間に配置される少なくとも１つの中間部をそれぞれ個別に設けられた定型の部品として有し、各部品が接合されることにより形成されるキャビネットを備えている。 In order to solve the above problems, an air conditioner indoor unit according to an aspect of the present invention includes a left end portion, a right end portion, and at least one intermediate portion disposed between the left end portion and the right end portion. Each is provided as a standard part provided individually, and is provided with a cabinet formed by joining the parts.

A blower 4 and a heat exchanger 5 are provided inside the main body 2. Further, an air outlet 23 is formed in the front portion of the main body 2.
　室内機１において、第１吸込口２１の内側（下側）には、第１フィルタ２４が設けられ、第２吸込口２２の内側（上側）には、第２フィルタ２５が設けられている。第１フィルタ２４は、例えばプレフィルタに相当する機能を有するフィルタである。第１フィルタ２４は、第２フィルタ２５よりも低性能であり、かつ第２フィルタ２５よりも通風抵抗が小さい。第２フィルタ２５は、例えばＨＥＰＡフィルタ(High Efficiency Particulate Air Filter)である。第２フィルタ２５は、第１フィルタ２４よりも高性能であり、かつ第１フィルタ２４よりも通風抵抗が大きいフィルタである。 In the indoor unit 1, a first filter 24 is provided on the inner side (lower side) of the first suction port 21, and a second filter 25 is provided on the inner side (upper side) of the second suction port 22. The first filter 24 is a filter having a function corresponding to, for example, a prefilter. The first filter 24 has a lower performance than the second filter 25 and has a lower ventilation resistance than the second filter 25. The second filter 25 is, for example, a HEPA filter (High Efficiency Particulate Air Filter). The second filter 25 is a filter that has higher performance than the first filter 24 and has a larger ventilation resistance than the first filter 24.
　室内機１では、第１吸込口２１から吸い込まれた空気は、第１フィルタ２４、送風機４および熱交換器５を経て吹出口２３から吹き出される。また、第２吸込口２２から吸い込まれた空気は、第２フィルタ２５、送風機４および熱交換器５を経て吹出口２３から吹き出される。 In the indoor unit 1, the air sucked from the first suction port 21 is blown out from the outlet 23 through the first filter 24, the blower 4 and the heat exchanger 5. Further, the air sucked from the second suction port 22 is blown out from the blower outlet 23 through the second filter 25, the blower 4 and the heat exchanger 5.
　第１吸込口２１には、第１吸込口２１を開閉する開閉蓋２６が設けられている。 The first suction port 21 is provided with an opening / closing lid 26 that opens and closes the first suction port 21.

FIG. 3 is an exploded perspective view of each main part in the main body 2. FIG. 4 is a perspective view of a state in which a part of the main part is assembled.
　図３および図４に示すように、本体部２は、送風機４、熱交換器５、モータ６、キャビネット７、ドレンパン８および仕切部材９を備えている。なお、図３では、便宜上、モータ６が省略されている。 3 and 4, the main body 2 includes a blower 4, a heat exchanger 5, a motor 6, a cabinet 7, a drain pan 8, and a partition member 9. In FIG. 3, the motor 6 is omitted for convenience.
　キャビネット７は、室内機１の後部に設けられ、送風機４、熱交換器５、モータ６およびドレンパン８を支持する。キャビネット７の前側は開放されている。 The cabinet 7 is provided at the rear part of the indoor unit 1 and supports the blower 4, the heat exchanger 5, the motor 6 and the drain pan 8. The front side of the cabinet 7 is open.
　キャビネット７に囲まれる空間には、複数（ここでは２個）の送風機４と、モータ６とが配置されている。送風機４は、例えばシロッコファンであり、羽根車４１と、羽根車４１を覆うケーシング４２とを有している。送風機４は、左側に１個、右側に１個、合計で２個設けられている。羽根車４１は、中心にシャフト４１ａを有している。隣り合う送風機４のシャフト４１ａは、それぞれ、送風機４の間に配置されたモータ６に連結されている。したがって、送風機４は、モータ６に駆動されて回転する。 In a space surrounded by the cabinet 7, a plurality of (in this case, two) blowers 4 and a motor 6 are arranged. The blower 4 is a sirocco fan, for example, and includes an impeller 41 and a casing 42 that covers the impeller 41. A total of two blowers 4 are provided, one on the left side and one on the right side. The impeller 41 has a shaft 41a at the center. The shafts 41 a of the adjacent blowers 4 are connected to the motor 6 disposed between the blowers 4. Therefore, the blower 4 is driven by the motor 6 and rotates.
　ケーシング４２には、羽根車４１の軸方向の両方の側面に開口する吸込部４２ａが形成されている。また、ケーシング４２には、羽根車４１の外周側に面して開口する吹出部４２ｂが形成されている。これにより、送風機４は、吸込部４２ａから空気を吸い込み、吸い込んだ空気を吹出部４２ｂから吹き出す。 The casing 42 is formed with a suction portion 42 a that opens on both side surfaces of the impeller 41 in the axial direction. Further, the casing 42 is formed with a blowing portion 42 b that opens toward the outer peripheral side of the impeller 41. Thereby, the air blower 4 inhales air from the suction part 42a, and blows off the sucked air from the blowing part 42b.
　ドレンパン８は、キャビネット７の前端部とねじにて連結され、キャビネット７によって支持されている。ドレンパン８にはドレンパイプ８１が接続されており、熱交換器５にて生じた水は、ドレンパン８に受け止められ、ドレンパイプ８１を通じて排出される。 The drain pan 8 is connected to the front end portion of the cabinet 7 with screws and is supported by the cabinet 7. A drain pipe 81 is connected to the drain pan 8, and water generated in the heat exchanger 5 is received by the drain pan 8 and discharged through the drain pipe 81.
　仕切部材９は、キャビネット７の前方位置かつドレンパン８の上に配置されている。仕切部材９は、キャビネット７の前端部と連結されることにより、キャビネット７に支持されている。送風機４およびモータ６は、ねじ締結にて仕切部材９に固定されている。 The partition member 9 is disposed in front of the cabinet 7 and on the drain pan 8. The partition member 9 is supported by the cabinet 7 by being connected to the front end portion of the cabinet 7. The blower 4 and the motor 6 are fixed to the partition member 9 by screw fastening.
　熱交換器５は、仕切部材９の前に配置されて、仕切部材９に固定されている。熱交換器５は、冷媒を流す伝熱管５１（配管）を有している。熱交換器５は、伝熱管５１内を流れる冷媒と熱交換を行うことによって、送風機４から送られる空気を冷却または加熱する。 The heat exchanger 5 is disposed in front of the partition member 9 and is fixed to the partition member 9. The heat exchanger 5 has a heat transfer tube 51 (pipe) through which a refrigerant flows. The heat exchanger 5 cools or heats the air sent from the blower 4 by exchanging heat with the refrigerant flowing in the heat transfer tube 51.
　送風機４、熱交換器５、モータ６、ドレンパン８および仕切部材９は、キャビネット７に取り付けられる、室内機１の構成部品である。 The blower 4, the heat exchanger 5, the motor 6, the drain pan 8, and the partition member 9 are components of the indoor unit 1 that are attached to the cabinet 7.

　キャビネット７Ｂにおいて、左端部７１と右端部７２との間に３つの中間部７３が配置されている。隣接する２つの中間部７３は、配管部７４によって互いに接続されている。このように、キャビネット７Ｂにおいても、配管部７４が２つの中間部７３を接続する部品を兼ねている。 In the cabinet 7B, three intermediate portions 73 are arranged between the left end portion 71 and the right end portion 72. Two adjacent intermediate portions 73 are connected to each other by a piping portion 74. Thus, also in the cabinet 7B, the piping part 74 serves as a part for connecting the two intermediate parts 73.
　左端部７１と中間部７３との接合、中間部７３と配管部７４との接合、右端部７２と中間部７３との接合は、上述したキャビネット７Ａにおけるこれらの接合と同じであるので、ここではその説明を省略する。 Since the joining of the left end 71 and the intermediate part 73, the joining of the intermediate part 73 and the piping part 74, and the joining of the right end part 72 and the intermediate part 73 are the same as these joints in the cabinet 7A described above, here The description is omitted.
　キャビネット７Ｂは、キャビネット７のほぼ３倍の長さを有する長尺に形成されることから、配管部７４が中間部７３の荷重を受けるため、配管部７４の負担が大きくなる。このため、キャビネット７Ｂも、補強部材によって補強されている。キャビネット７Ｂの補強は、３つの中間部７３に跨がる補強部材を各中間部７３の背面部７３１における外面およびキャビネット７Ｂの前面側の少なくともいずれか一方に固定されることで施される。あるいは、隣接する２つの中間部７３に対してキャビネット７Ａと同じようにして補強を施してもよい。 Since the cabinet 7 </ b> B is formed to have a length approximately three times that of the cabinet 7, the piping portion 74 receives the load of the intermediate portion 73, so that the burden on the piping portion 74 increases. For this reason, the cabinet 7B is also reinforced by the reinforcing member. The cabinet 7B is reinforced by fixing a reinforcing member straddling the three intermediate portions 73 to at least one of the outer surface of the back surface portion 731 of each intermediate portion 73 and the front surface side of the cabinet 7B. Alternatively, reinforcement may be applied to the two adjacent intermediate portions 73 in the same manner as the cabinet 7A.
　（キャビネット７，７Ａ，７Ｂの利点）
　以上のように、キャビネット７，７Ａ，７Ｂは、左端部７１、右端部７２および左端部７１と右端部７２との間に配置される中間部７３をそれぞれ個別の部品として有し、各部品が接合されることにより形成される。また、左端部７１、右端部７２および中間部７３は、それぞれ定型の部品として形成される。 (Advantages of cabinets 7, 7A, 7B)
As described above, the cabinets 7, 7A, and 7B have the left end portion 71, the right end portion 72, and the intermediate portion 73 disposed between the left end portion 71 and the right end portion 72 as individual components. It is formed by joining. Further, the left end portion 71, the right end portion 72, and the intermediate portion 73 are each formed as a standard part.
　これにより、キャビネット７，７Ａ，７Ｂを構成する各部品を室内機１の異なる機種間で共通化することができる。例えば、長さ（横幅）のサイズが異なる室内機１を製造する場合、中間部７３の数を異ならせることで、所望の長さのキャビネット７，７Ａ，７Ｂなどを得ることができる。それゆえ、各種の部品の組み合わせによって、異なるサイズの機種の室内機１を製造することができる。 Thereby, each component constituting the cabinet 7, 7A, 7B can be shared among different models of the indoor unit 1. For example, when manufacturing the indoor unit 1 having different lengths (widths), the cabinets 7, 7A, 7B having desired lengths can be obtained by changing the number of the intermediate portions 73. Therefore, different sizes of indoor units 1 can be manufactured by combining various components.
　また、１種類の中間部７３を１つ以上有することで異なる長さのキャビネット７，７Ａ，７Ｂが構成される。これにより、異なる長さの中間部が必要な従来技術と比べて部品の種類を少なくすることで、必要な金型の種類を少なくすることができる。したがって、金型に要する費用を低減することができる。しかも、同一種の部品を用いて製造できる室内機１の台数が増えるため、部品単価を低減することができる。 Moreover, cabinets 7, 7A and 7B having different lengths are configured by having one or more kinds of one intermediate portion 73. Thereby, compared with the prior art which requires the intermediate part of different length, the kind of required metal mold | die can be decreased by reducing the kind of components. Therefore, the cost required for the mold can be reduced. In addition, since the number of indoor units 1 that can be manufactured using the same type of components increases, the unit cost of components can be reduced.
　また、部品管理を容易にすることができる。特に、最も長い部品である中間部７３については、室内機１を組み立てる前に中間部７３を保管するための１種類の箱を用意すればよい。それゆえ、中間部７３の保管、輸送等を容易にすることができる。 Also, parts management can be facilitated. In particular, for the intermediate part 73 which is the longest part, one type of box for storing the intermediate part 73 may be prepared before the indoor unit 1 is assembled. Therefore, storage, transportation, etc. of the intermediate part 73 can be facilitated.
　キャビネット７は、左端部７１と、右端部７２と、１つの中間部７３と、配管部７４とを有している。配管部７４は、左端部７１または右端部７２と中間部７３との間に配置されるとともに、左端部７１または右端部７２と中間部７３と接合され、定型の部品として形成される。 The cabinet 7 has a left end portion 71, a right end portion 72, one intermediate portion 73, and a piping portion 74. The piping portion 74 is disposed between the left end portion 71 or the right end portion 72 and the intermediate portion 73, and is joined to the left end portion 71 or the right end portion 72 and the intermediate portion 73 to be formed as a standard part.
　キャビネット７Ａは、左端部７１と、右端部７２と、２つの中間部７３と、配管部７４とを有している。また、キャビネット７Ｂは、左端部７１と、右端部７２と、３つの中間部７３と、配管部７４とを有している。左端部７１と左端部７１に隣接する中間部７３とが接合され、右端部７２と右端部７２に隣接する中間部７３とが接合される。配管部７４は、隣接する中間部７３の間に配置されるとともに、隣接する中間部７３に接合される。 The cabinet 7A has a left end portion 71, a right end portion 72, two intermediate portions 73, and a piping portion 74. Further, the cabinet 7 </ b> B has a left end portion 71, a right end portion 72, three intermediate portions 73, and a piping portion 74. The left end portion 71 and the intermediate portion 73 adjacent to the left end portion 71 are joined, and the right end portion 72 and the intermediate portion 73 adjacent to the right end portion 72 are joined. The piping part 74 is disposed between the adjacent intermediate parts 73 and joined to the adjacent intermediate part 73.
　これにより、キャビネット７，７Ａ，７Ｂにおいて、配管部７４を接続用の部品として利用することができる。 Thereby, in the cabinets 7, 7A, 7B, the piping part 74 can be used as a component for connection.
　キャビネット７Ａは、２つの隣接する前記中間部にわたって取り付けられる補強部材７６，７７を有している。キャビネット７Ｂは、２つ以上の隣接する中間部７３にわたって接続される補強部材を有している。 The cabinet 7A has reinforcing members 76 and 77 attached over two adjacent intermediate portions. The cabinet 7B has a reinforcing member connected across two or more adjacent intermediate portions 73.
　これにより、キャビネット７Ａ，７Ｂの剛性を高めることができる。 This can increase the rigidity of the cabinets 7A and 7B.
　左端部７１、右端部７２、中間部７３、配管部７４および接続部７５がそれぞれ隣接する部品と接合される方向（各部品同士が接合される方向）は、本体部２の長手方向、すなわち左端部７１、右端部７２、中間部７３、配管部７４および接続部７５の各部品が並ぶ方向である。なお、ここでの接合は、接合のためのねじ締結を含むものとする。また、上記の部品として、後述する実施形態２における短縮中間部７８（図１２参照）も含まれる。 The direction in which the left end portion 71, the right end portion 72, the intermediate portion 73, the piping portion 74, and the connecting portion 75 are joined to adjacent components (the direction in which the components are joined) is the longitudinal direction of the main body portion 2, that is, the left end In this direction, the parts 71, right end 72, intermediate part 73, piping part 74, and connection part 75 are arranged. In addition, joining here shall include the screw fastening for joining. Further, as the above-described components, a shortened intermediate portion 78 (see FIG. 12) in the second embodiment described later is also included.
　キャビネット７，７Ａ，７Ｂの前側に取り付けられる室内機１の構成部品によって、キャビネット７の後ろから前に向かう方向およびキャビネット７の上部から下方に向かう方向に力が作用する。これに対し、各部品が並ぶ方向は構成部品による力が作用する方向とほぼ直交する方向である。したがって、構成部品による力に対する剛性を高めることができる。 Forces act in the direction from the back of the cabinet 7 to the front and the direction from the top of the cabinet 7 downward by the components of the indoor unit 1 attached to the front side of the cabinets 7, 7A, 7B. On the other hand, the direction in which the parts are arranged is a direction substantially orthogonal to the direction in which the force from the component acts. Therefore, the rigidity with respect to the force by a component can be improved.
　左端部７１、右端部７２、中間部７３、配管部７４および接続部７５がそれぞれ隣接する部品と接合する接合部（各部品同士が接合される接合部）は、少なくとも１つの屈曲部を有している。 The left end portion 71, the right end portion 72, the intermediate portion 73, the piping portion 74, and the connecting portion 75 are joined to adjacent components (joined portions where the respective components are joined) have at least one bent portion. ing.
　例えば、左端部７１の接合部７１２と、右端部７２の接合部７２２と、中間部７３の左接合部７３３および右接合部７３４と、配管部７４の左接合部７４２および右接合部７４３とは、１つの屈曲部を有する逆Ｌ字形状に形成されている。また、左端部７１の接合部７１２と、右端部７２の接合部７２２と、中間部７３の左接合部７３３および右接合部７３４と、配管部７４の左接合部７４２および右接合部７４３とは、２つの屈曲部を有するコ字形状（２つの平行部分とこれらの平行部分の一端同士を繋ぐ部分とを有する形状）に形成されてもよい。 For example, the joining portion 712 of the left end portion 71, the joining portion 722 of the right end portion 72, the left joining portion 733 and the right joining portion 734 of the intermediate portion 73, and the left joining portion 742 and the right joining portion 743 of the piping portion 74 are It is formed in an inverted L shape having one bent portion. Further, the joining portion 712 of the left end portion 71, the joining portion 722 of the right end portion 72, the left joining portion 733 and the right joining portion 734 of the intermediate portion 73, and the left joining portion 742 and the right joining portion 743 of the piping portion 74 are as follows. It may be formed in a U-shape having two bent portions (a shape having two parallel portions and a portion connecting one end of these parallel portions).
　なお、上記の接合部には、後述する実施形態２における短縮中間部７８の左接合部７８３および右接合部７８４（図１２参照）も含まれる。 In addition, the above-described joint portion includes a left joint portion 783 and a right joint portion 784 (see FIG. 12) of the shortened intermediate portion 78 in Embodiment 2 described later.
　これにより、接合部の剛性を高めることができる。 This can increase the rigidity of the joint.

The shortened intermediate portion 78 is also formed of resin by an injection mold as in the case of other components.
　短縮中間部７８は、中間部７３の右接合部７３４と配管部７４の左接合部７４２との間に配置されている。短縮中間部７８は、中間部７３よりも短く形成されており、例えば、短縮中間部７８は、中間部７３の１／３の長さを有する。短縮中間部７８は、中間部７３に接合されることで中間部７３を補足するために設けられた部品である。短縮中間部７８は、背面部７８１と、上枠部７８２と、左接合部７８３と、右接合部７８４とを有している。 The shortened intermediate portion 78 is disposed between the right joint portion 734 of the intermediate portion 73 and the left joint portion 742 of the piping portion 74. The shortened intermediate portion 78 is formed shorter than the intermediate portion 73. For example, the shortened intermediate portion 78 has a length that is 1/3 of the intermediate portion 73. The shortened intermediate portion 78 is a component provided to supplement the intermediate portion 73 by being joined to the intermediate portion 73. The shortened intermediate portion 78 has a back surface portion 781, an upper frame portion 782, a left joint portion 783, and a right joint portion 784.
　背面部７８１は、長方形または正方形を成す部分である。 The back surface portion 781 is a rectangular or square portion.
　上枠部７８２は、中央部７８２ａと、前部７８２ｂとを有している。中央部７８２ａは、背面部７８１の内面における上端の中央から前方に突出するように形成されている。中央部７８２ａは、キャビネット７Ｃの前後方向の所定の厚みを確保するために設けられている。前部７８２ｂは、中央部７８２ａの前端から左右に背面部７８１の両端まで細長く伸びるように形成されている。 The upper frame part 782 has a center part 782a and a front part 782b.

The central portion 782a is provided to ensure a predetermined thickness in the front-rear direction of the cabinet 7C. The front part 782b is formed so as to extend elongated from the front end of the central part 782a to the left and right ends of the back part 781.
　左接合部７８３は、中間部７３の右接合部７３４と接合される部分である。左接合部７８３は、逆Ｌ字形状を成しており、背面部７８１および上枠部７８２の左端から左側に突出するように形成されている。左接合部７８３は、右接合部７３４が嵌まり込むように凹形状に形成されている。 The left joint portion 783 is a portion joined to the right joint portion 734 of the intermediate portion 73. The left joint portion 783 has an inverted L shape, and is formed so as to protrude from the left end of the back surface portion 781 and the upper frame portion 782 to the left side. The left joint portion 783 is formed in a concave shape so that the right joint portion 734 is fitted therein.
　右接合部７８４は、配管部７４と接合される部分である。右接合部７８４は、逆Ｌ字形状を成しており、配管部７４の左接合部７４２に嵌まり込むように、背面部７８１および上枠部７８２の右端から右側に突出するように形成されている。 The right joint part 784 is a part joined to the pipe part 74. The right joint portion 784 has an inverted L shape, and is formed so as to protrude rightward from the right end of the back surface portion 781 and the upper frame portion 782 so as to fit into the left joint portion 742 of the piping portion 74. ing.
　図１２の（ｃ）に示すように、本体部２Ｃは、このように構成されるキャビネット７Ｃを備える。キャビネット７Ｃには、中間部７３に３台の送風機４と１台のモータ６とが取り付けられ、短縮中間部７８に１台の送風機４が取り付けられる。 As shown in FIG. 12 (c), the main body 2C includes a cabinet 7C configured as described above. In the cabinet 7 </ b> C, three blowers 4 and one motor 6 are attached to the intermediate portion 73, and one blower 4 is attached to the shortened intermediate portion 78.
　なお、ここでの送風機４およびモータ６は、実施形態１のキャビネット７に取り付けられる送風機４およびモータ６に比べて軸方向のサイズが短い。 Note that the blower 4 and the motor 6 here are shorter in the axial direction than the blower 4 and the motor 6 attached to the cabinet 7 of the first embodiment.
　（キャビネット７Ｃの利点）
　キャビネット７Ｃは、左端部７１または右端部７２と前記中間部との間に配置され、前記中間部より短い短縮中間部をさらに有し、前記短縮中間部は、定型の部品として形成される。 (Advantages of cabinet 7C)
The cabinet 7C is disposed between the left end portion 71 or the right end portion 72 and the intermediate portion, and further includes a shortened intermediate portion shorter than the intermediate portion, and the shortened intermediate portion is formed as a standard part.
　仕様に基づく能力を達成するために４台の送風機４を必要とする室内機１を作製するには、中間部７３だけでは足りない。これに対し、中間部７３を２つ接続すれば、４台の送風機４を取り付けることができるが、スペースが余ってしまい、キャビネット７Ｃが無駄に長くなる。このような不都合に対し、短縮中間部７８を補足することにより、１つの中間部７３のみでは不足する１台の送風機４を取り付けるスペースのみを確保することができる。したがって、１つの中間部７３を用いた室内機１よりもサイズを大きくする際に、さらに１つの中間部７３を追加することではサイズが大きくなりすぎる場合、短縮中間部７８を追加することで所望のサイズのキャビネット７Ｃを得ることができる。 In order to produce the indoor unit 1 that requires four blowers 4 to achieve the capacity based on the specifications, the intermediate part 73 alone is not sufficient. On the other hand, if two intermediate parts 73 are connected, four fans 4 can be attached, but space is left and the cabinet 7C becomes unnecessarily long. For such inconvenience, by supplementing the shortened intermediate portion 78, it is possible to secure only a space for mounting one blower 4 which is insufficient with only one intermediate portion 73. Therefore, when the size is made larger than that of the indoor unit 1 using one intermediate portion 73 and the size becomes too large by adding one intermediate portion 73, it is desirable to add the shortened intermediate portion 78. Can be obtained.
