Description

本発明は、空気調和機の室内機に関し、さらに詳しく言えば、設置場所の状況に応じて室内機内への空気吸込方向を選択できるようにした技術に関するものである。 TECHNICAL FIELD The present invention relates to an indoor unit of an air conditioner, and more specifically, to a technology that enables selection of the air suction direction into the indoor unit according to the conditions of the installation location.

空気調和機の室内機の一つとして、被空調室の天井裏に設置される天井埋込ダクト型がある。天井埋込ダクト型の室内機は、高さが小さい天井裏の空間内に設置されることから扁平な直方体形状の筐体を備えている。筐体の内部は、仕切板によって熱交換器が配置される熱交換室と送風機が配置される送風機室に区画されている。 As one of the indoor units of air conditioners, there is a ceiling-embedded duct type that is installed behind the ceiling of a room to be air-conditioned. Since the ceiling-embedded duct type indoor unit is installed in a small space behind the ceiling, it has a flat rectangular parallelepiped housing. The interior of the housing is partitioned by a partition plate into a heat exchange chamber in which a heat exchanger is arranged and a blower chamber in which a blower is arranged.

送風機室側に室内空気を取り込む空気吸込口が設けられ、熱交換室側に熱交換された調和空気が吹き出される空気吹出口が設けられる。空気吸込口には空気吸込ダクトが接続され、空気吹出口には空気吹出ダクトが接続される。 An air inlet for taking in room air is provided on the blower chamber side, and an air outlet for blowing out heat-exchanged conditioned air is provided on the heat exchange chamber side. An air suction duct is connected to the air suction port, and an air blowing duct is connected to the air blowing port.

多くの場合、空気吹出口は筐体の前面側に配置され、空気吸込口は筐体の後面（背面）側に設けられるが、筐体の後面と天井裏の造作（例えば、壁や柱）との間が狭く、空気吸込口に空気吸込ダクトを接続することができない場合がある。 In many cases, the air outlet is placed on the front side of the housing, and the air inlet is provided on the rear (rear) side of the housing. In some cases, the air suction duct cannot be connected to the air suction port due to the narrow space between the

この点を考慮して、送風機室側の空気吸込口を、筐体の後面から空気を吸い込む後面吸込口と筐体の底面（送風機室の底面）から空気を吸い込む底面吸込口の２つとし、そのいずれかを空気吸込口として選択できるようにした室内機がある。 In consideration of this point, two air inlets are provided on the blower chamber side: a rear inlet for sucking air from the rear of the housing and a bottom inlet for sucking air from the bottom of the housing (bottom of the fan chamber). There is an indoor unit in which either of them can be selected as an air suction port.

この室内機においてはアタッチメントパネルとしてのふさぎ板を有している。室内機が後面吸込口から空気を吸い込む場合（以下、後面吸込方式ともいう）にはふさぎ板によって底面吸込口を塞ぐ。一方、室内機が底面吸込口から空気を吸い込む場合（以下、底面吸込方式ともいう）にはふさぎ板によって後面吸込口を塞ぐ。 This indoor unit has a cover plate as an attachment panel. When the indoor unit sucks air from the rear suction port (hereinafter also referred to as a rear suction method), the bottom suction port is closed with a blocking plate. On the other hand, when the indoor unit sucks air from the bottom suction port (hereinafter also referred to as a bottom suction method), the rear suction port is closed with a blocking plate.

しかし、後面吸込口と底面吸込口の開口の面積（大きさ）が等しくない場合がある。特許文献１に記載された発明では、ふさぎ板をふさぎ板大とふさぎ板小の２枚で構成している。開口の面積の大きい吸込口を塞ぐ場合には、ふさぎ板大とふさぎ板小を重ねることなく並べて配置する。これに対して、開口の面積の小さい吸込口を塞ぐ場合には、ふさぎ板大とふさぎ板小の一部分を重ね合わせてその大きさを吸込口の大きさに合わせるようにしている。しかし、従来技術ではふさぎ板としてふさぎ板大とふさぎ板小の２枚を必要とするため、室内機の構成部品が増えてしまう。従って、室内機の組み立て作業に工数を要するうえ、部品の管理コストが上がるなどの問題があり、構成の簡素化の観点から好ましくない。 However, the areas (sizes) of the openings of the rear suction port and the bottom suction port may not be equal. In the invention described in Patent Document 1, the closing plate is composed of two pieces, a large closing plate and a small closing plate. When closing a suction port with a large opening area, a large closing plate and a small closing plate are arranged side by side without overlapping. On the other hand, when closing a suction port with a small opening area, a large sealing plate and a small sealing plate are overlapped to match the size of the suction port. However, in the prior art, two closing plates, a large closing plate and a small closing plate, are required, which increases the number of components of the indoor unit. Therefore, there are problems such as the need for man-hours to assemble the indoor unit, and the management cost of the parts increases.

したがって、本発明の課題は空気調和機の室内機において、空気吸込口を選択可能な場合であっても、室内機の構成部品を増やすことのない空気調和機の室内機を提供することにある。 Accordingly, it is an object of the present invention to provide an indoor unit for an air conditioner that does not increase the number of components of the indoor unit even if the air suction port can be selected. .

上記課題を解決するため、本発明は、底面に設けられた底面吸込口と側面に設けられた側面吸込口とを有する直方体形状の筐体と、上記底面吸込口および上記側面吸込口のいずれか一方を塞ぐアタッチメントパネルとを含む空気調和機の室内機において、上記アタッチメントパネルには、上記アタッチメントパネルを折り曲げるための折り曲げ部が形成さ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 a rectangular parallelepiped housing having a bottom suction port provided on a bottom surface and a side suction port provided on a side surface, and one of the bottom suction port and the side suction port. An air conditioner indoor unit including an attachment panel closing one side is characterized in that the attachment panel is formed with a bending portion for bending the attachment panel.

本発明によれば、空気調和機の室内機において、空気吸込口を選択可能な場合であっても、室内機の構成部品を増やすことのない空気調和機の室内機を提供することができる。 Advantageous Effects of Invention According to the present invention, it is possible to provide an indoor unit for an air conditioner without increasing the number of components of the indoor unit even when the air suction port is selectable.

次に、図１ないし図９を参照しながら、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 invention will be described with reference to FIGS. 1 to 9, but the invention is not limited thereto.

まず、図１と図２を参照して、本実施形態の説明において、空気調和機の室内機１は、例えば天井埋込ダクト型空気調和機の室内機であり、家屋の天井裏に設置される筐体１０を備えている。天井裏の空間は高さが低いため、天井裏に設置される筐体１０の形状は扁平な直方体である。筐体１０の四隅には、図示しない吊下げボルトにより当該筐体１０を天井裏の例えば躯体スラブに吊り下げるための吊下げフック１０１が設けられている。なお、本実施形態では、天井埋込ダクト型室内機を用いて説明を行うが、本発明の空気調和機の室内機はこれに限られず、室内空間に露出する天吊型室内機やダクト型室内機など様々な室内機に適用することができる。 First, referring to FIGS. 1 and 2, in the description of the present embodiment, an indoor unit 1 of an air conditioner is, for example, an indoor unit of a ceiling-embedded duct type air conditioner, and is installed in the ceiling of a house. A housing 10 is provided. Since the space behind the ceiling is low, the shape of the housing 10 installed in the ceiling is a flat rectangular parallelepiped. Suspension hooks 101 are provided at the four corners of the housing 10 for suspending the housing 10 from, for example, a frame slab behind the ceiling by means of suspension bolts (not shown). In this embodiment, a ceiling-embedded duct-type indoor unit is used for explanation, but the indoor unit of the air conditioner of the present invention is not limited to this, and a ceiling-suspended indoor unit or a duct-type indoor unit exposed to the indoor space is used. It can be applied to various indoor units such as indoor units.

筐体１０は、上面パネル１１、左側面パネル１２Ｌおよび右側面パネル１２Ｒを備えている。図４を併せて参照して、筐体１０の底面には、底蓋パネル１３とアタッチメントパネル１４とが配置される。筐体１０の前面１６と後面１５は空気流通口として開放されている。 The housing 10 includes a top panel 11, a left side panel 12L and a right side panel 12R. Also referring to FIG. 4 , a bottom lid panel 13 and an attachment panel 14 are arranged on the bottom surface of the housing 10 . A front surface 16 and a rear surface 15 of the housing 10 are open as air flow holes.

図２に示すように、筐体１０の内部は、仕切板２０によって左右に区画されており、その一方である後面１５側が熱交換室３０、他方である前面１６側が送風機室４０である。熱交換室３０の底面は底蓋パネル１３によって塞がれている。図示しないが、左側面パネル１２Ｌは仕切板２０の左側端部に固定され、右側面パネル１２Ｒは仕切板２０の右側端部に固定されている。 As shown in FIG. 2 , the interior of the housing 10 is divided into left and right by a partition plate 20 , one of which is the rear surface 15 side of which is a heat exchange chamber 30 , and the other of which is the front surface 16 side of which is a blower chamber 40 . The bottom surface of the heat exchange chamber 30 is closed by the bottom lid panel 13 . Although not shown, the left side panel 12L is fixed to the left end of the partition plate 20, and the right side panel 12R is fixed to the right end of the partition plate 20. As shown in FIG.

熱交換室３０内には、熱交換器３１とドレンパン３２とが設けられている。送風機室４０内には、送風機４１が設けられている。送風機４１にはシロッコファンが用いられている。本実施形態において、図３に示すように、送風機４１の台数は２台であるが、１台もしくは３台以上であってもよい。 A heat exchanger 31 and a drain pan 32 are provided in the heat exchange chamber 30 . A fan 41 is provided in the fan chamber 40 . A sirocco fan is used for the blower 41 . In this embodiment, as shown in FIG. 3, the number of blowers 41 is two, but may be one or three or more.

本実施形態によると、送風機４１の運転により、筐体１０の前面１６側から室内空気が吸い込まれ、熱交換器３１にて冷媒と熱交換された調和空気が筐体１０の後面１５側から吹き出される。 According to this embodiment, due to the operation of the blower 41, indoor air is sucked from the front surface 16 side of the housing 10, and the conditioned air heat-exchanged with the refrigerant in the heat exchanger 31 is blown out from the rear surface 15 side of the housing 10. be done.

したがって、筐体１０の前面１６側に図示しない空気吸込ダクトが接続され、筐体１０の後面１５側に図示しない空気吹出ダクトが接続されるが、筐体１０の前面１６と天井裏の造作（例えば、壁や柱）との間に空気吸込ダクトを接続するための十分な空間がない場合、筐体１０の前面１６側に空気吸込ダクトを接続することができない。 Therefore, an air intake duct (not shown) is connected to the front surface 16 side of the housing 10, and an air outlet duct (not shown) is connected to the rear surface 15 side of the housing 10. For example, if there is not enough space for connecting the air suction duct between the housing 10 and the wall or column, the air suction duct cannot be connected to the front face 16 side of the housing 10 .

そこで、本発明では、送風機室４０側の空気吸込口を、筐体１０の前面１６から空気を吸い込む前面吸込口１６１と、筐体１０の底面（送風機室４０の底面）から空気を吸い込む底面吸込口１６２の２つとし、そのいずれかを選択できるようにしている。この空気吸込口の選択は、アタッチメントパネル１４の取付位置を変更することにより行われる。なお、アタッチメントパネル１４はメンテナンス用のサービスパネルでもある。 Therefore, in the present invention, the air suction port on the blower chamber 40 side is divided into a front suction port 161 that sucks air from the front surface 16 of the housing 10 and a bottom suction port that sucks air from the bottom surface of the housing 10 (bottom surface of the blower chamber 40). There are two ports 162, one of which can be selected. The selection of the air suction port is performed by changing the attachment position of the attachment panel 14 . The attachment panel 14 is also a service panel for maintenance.

図４ａおよび図４ｂはアタッチメントパネル１４にて底面吸込口１６２を塞いで、筐体１０を前面吸込口１６１より室内空気を吸い込む前面吸込方式とした状態を示している。これに対して、図５はアタッチメントパネル１４にて前面吸込口１６１を塞いで、筐体１０を底面吸込口１６２より室内空気を吸い込む底面吸込方式とした状態を示している。いずれの場合にも、吸込口にはエアフィルタを有する吸込グリル１７が設けられる。本実施形態において、前面吸込口１６１と底面吸込口１６２の開口の面積（大きさ）は等しいことで吸込グリル１７は前面吸込口１６１と底面吸込口１６２とに兼用される。 4a and 4b show a state in which the attachment panel 14 closes the bottom air intake 162 and the housing 10 is of a front air intake system in which indoor air is drawn in through the front air intake 161. FIG. On the other hand, FIG. 5 shows a state in which the attachment panel 14 closes the front air intake 161 and the housing 10 adopts a bottom air intake system in which indoor air is drawn in through the bottom air intake 162 . In either case, the intake is provided with an intake grille 17 with an air filter. In this embodiment, the front suction port 161 and the bottom suction port 162 have the same opening area (size), so that the suction grille 17 is used both as the front suction port 161 and the bottom suction port 162 .

しかし、前面吸込口１６１と底面吸込口１６２では、その周囲で吸込グリル１７を使用しない吸込口（前面吸込口１６１または底面吸込口１６２）を塞ぐ、アタッチメントパネル１４を固定するネジ止め位置が異なる。 However, the front suction port 161 and the bottom suction port 162 are different in the screwing position for fixing the attachment panel 14 that closes the suction port (the front suction port 161 or the bottom suction port 162) around which the suction grille 17 is not used.

すなわち、図３に示すように、前面吸込口１６１と底面吸込口１６２を塞ぐアタッチメントパネル１４が取り付けられる箇所は、ともにその横幅（左側面パネル１２ｌと右側面パネル１２Ｒ間に沿った幅）ＷＡは等しいが、縦幅（前面吸込口１６１では上下方向に沿った幅ＷＢ１、底面吸込口１６２側では前後方向に沿った幅ＷＢ２）については、底面吸込口１６２側の幅ＷＢ２の方が前面吸込口１６１側の幅ＷＢ１より長い。アタッチメントパネル１４を固定するネジ止め部が底蓋パネル１３の仕切板２０の下端にあるため、アタッチメントパネル１４は、底面吸込口１６２の前後方向に沿った幅と底蓋パネル１３の一端１３１の前後方向に沿った幅とを足し合わせた長さを有して形成されている。すなわち、アタッチメントパネル１４は図６に示すように、横幅ＷＡ、縦幅ＷＢ２を有する一枚構成の板金材からなる。 That is, as shown in FIG. 3, the width (the width along between the left side panel 12l and the right side panel 12R) WA is Although they are equal, the vertical width (the width WB1 along the vertical direction at the front suction port 161 and the width WB2 along the front-rear direction at the bottom suction port 162 side) is such that the width WB2 at the bottom suction port 162 side is larger than that at the front suction port. It is longer than the width WB1 on the 161 side. Since the screw fixing portion for fixing the attachment panel 14 is located at the lower end of the partition plate 20 of the bottom lid panel 13 , the attachment panel 14 has a width along the front-rear direction of the bottom suction port 162 and a front-rear width of one end 131 of the bottom lid panel 13 . It is formed to have a length that is the sum of the width along the direction. That is, as shown in FIG. 6, the attachment panel 14 is made of a single sheet metal material having a width WA and a length WB2.

そのため図７に示すように、底面吸込方式とするにあたって、アタッチメントパネル１４の、縦幅ＷＢ２方向の一辺（図６では下辺）１４ａを、筐体１０の底面と後面とが交差する角部１０ａ（図３参照）に合わせて、アタッチメントパネル１４にて後面吸込口１６１を塞ぐ場合、アタッチメントパネル１４の一部分が筐体１０の上面側にはみ出す。 Therefore, as shown in FIG. 7, in adopting the bottom suction method, one side (lower side in FIG. 6) 14a of the attachment panel 14 in the vertical width WB2 direction is positioned at the corner 10a ( 3), when the attachment panel 14 closes the rear suction port 161, a portion of the attachment panel 14 protrudes from the upper surface side of the housing 10. As shown in FIG.

ここで説明の便宜上、アタッチメントパネル１４において、後面吸込口１６１に対応する大きさの部分をパネル本体１４１、筐体１０の上面側にはみ出す部分をはみ出し部１４２という。 For convenience of explanation, the portion of the attachment panel 14 corresponding to the rear suction port 161 is called a panel main body 141 , and the portion that protrudes to the upper surface side of the housing 10 is called a protruding portion 142 .

本発明において、はみ出し部１４２は上面パネル１１に重なるように折り曲げ可能であり、アタッチメントパネル１４は、図６に示すように、はみ出し部１４２を折り曲げるための折り曲げ部１４３を備えている。折り曲げ部１４３は、パネル本体１４１とはみ出し部１４２の境界線に沿って延在している。折り曲げ部１４３には、その折り曲げを容易とするため、機械的強度がアタッチメントパネル１４の他の部位よりも機械的強度が弱められた脆弱部１４３ａが形成されている。 In the present invention, the protruding portion 142 can be folded so as to overlap the top panel 11, and the attachment panel 14 is provided with a folding portion 143 for folding the protruding portion 142, as shown in FIG. The bent portion 143 extends along the boundary line between the panel main body 141 and the protruding portion 142 . The bent portion 143 is formed with a fragile portion 143a having a lower mechanical strength than other portions of the attachment panel 14 in order to facilitate the bending.

本実施形態において、脆弱部１４３ａは、図８に示すように、パネル本体１４１とはみ出し部１４２の境界線に沿って所定の間隔をもって一列状に形成された複数の長孔（スリット）１４３ｂからなる。 In this embodiment, as shown in FIG. 8, the fragile portion 143a consists of a plurality of long holes (slits) 143b formed in a row at predetermined intervals along the boundary line between the panel body 141 and the protruding portion 142. .

これによれば、室内機１を設置する天井裏において、筐体１０の後面１６と天井裏の造作（例えば、壁や柱）との間が狭く、筐体１０の後面１６と天井裏の造作との間に空気吸込ダクトを接続するための十分な空間がないため、筐体１０の後面吸込口１６１に空気吸込ダクトを接続することができない場合、室内機１を底面吸込方式とする際に、アタッチメントパネル１４にて筐体１０の後面吸込口１６１を塞いではみ出し部１４２を上面パネル１１に重なるように折り曲げればよく、一枚のアタッチメントパネル１４にて吸込方式の選択に対応することができる。 According to this, in the ceiling space where the indoor unit 1 is installed, the space between the rear surface 16 of the housing 10 and the ceiling space features (for example, walls and pillars) is narrow, and the space between the rear surface 16 of the housing 10 and the ceiling space features is narrow. If the air suction duct cannot be connected to the rear suction port 161 of the housing 10 because there is not enough space for connecting the air suction duct between the The attachment panel 14 can close the rear suction port 161 of the housing 10 and bend the protruding portion 142 so as to overlap the upper panel 11, and the suction method can be selected with one attachment panel 14. can.

当該室内機の出荷時には、アタッチメントパネル１４は底面吸込口１６２を塞ぐように筐体１０の底面にネジ止めされる。その際、製品の搬送時等の衝撃に耐えるように筐体１０の底面側の機械的強度を高めるため、アタッチメントパネル１４はその一端側であるはみ出し部１４２が熱交換室３０の底面を覆う底蓋パネル１３の一端部１３１とともに仕切板２０にネジ止めされる。 When the indoor unit is shipped, the attachment panel 14 is screwed to the bottom surface of the housing 10 so as to close the bottom suction port 162 . At this time, in order to increase the mechanical strength of the bottom side of the housing 10 so as to withstand impacts during transportation of the product, the attachment panel 14 has a protruding portion 142 at one end thereof that covers the bottom of the heat exchange chamber 30. It is screwed to the partition plate 20 together with one end portion 131 of the lid panel 13 .

図９は図２のＸ部拡大図である。図９を参照して、仕切板２０は底蓋パネル１３の一端部１３１とアタッチメントパネル１４の一端部であるはみ出し部１４２がネジ止めされる脚部２１を有している。脚部２１は、熱交換室３０内のドレンパン３２と干渉しないように、機械室４０側に向けてＬ字状に折り曲げられていることが好ましい。 9 is an enlarged view of the X portion of FIG. 2. FIG. Referring to FIG. 9, the partition plate 20 has a leg portion 21 to which one end portion 131 of the bottom lid panel 13 and a protruding portion 142 which is one end portion of the attachment panel 14 are screwed. The leg portion 21 is preferably bent in an L shape toward the machine room 40 so as not to interfere with the drain pan 32 inside the heat exchange chamber 30 .

底蓋パネル１３の一端部１３１は、仕切板２０の脚部２１の下面に沿って配置され、同様に、アタッチメントパネル１４の一端部であるはみ出し部１４２も仕切板２０の脚部２１の下面に沿って配置される。 One end portion 131 of the bottom lid panel 13 is arranged along the lower surface of the leg portion 21 of the partition plate 20, and similarly, the protruding portion 142, which is one end portion of the attachment panel 14, is also arranged on the lower surface of the leg portion 21 of the partition plate 20. placed along.

底蓋パネル１３の一端部１３１とアタッチメントパネル１４のはみ出し部１４２は互いに重ねられた状態で仕切板２０の脚部２１にネジ止めされる。これにより、筐体１０の底面側の機械的強度が高められる。また、折り曲げ部１４３は底蓋パネル１３と重なることで長孔（スリット）１４３ｂが塞がれる。 One end portion 131 of the bottom lid panel 13 and the protruding portion 142 of the attachment panel 14 are screwed to the leg portion 21 of the partition plate 20 while being overlapped with each other. This increases the mechanical strength of the bottom side of the housing 10 . Further, the bent portion 143 overlaps the bottom lid panel 13 to close the long hole (slit) 143b.

アタッチメントパネル１４のはみ出し部１４２には、図６に梨地模様で示すように例えばＦＰＥ（フォームドポリエチレン）からなる緩衝材１４４が設けられている。このため、底蓋パネル１３の一端部１３１を上、その下にアタッチメントパネル１４のはみ出し部１４２を重ねて配置して仕切板２０の脚部２１にネジ止めすることが好ましく、これによれば、緩衝材１４４によりネジ止め部分の気密性を確保することができる。また、例えば室内機１を設置場所まで搬送する際に筐体１０に振動が加わっても、アタッチメントパネル１４を仕切板２０で強固に保持することができる。 A protruding portion 142 of the attachment panel 14 is provided with a cushioning material 144 made of, for example, FPE (formed polyethylene), as indicated by a satin pattern in FIG. For this reason, it is preferable to place one end portion 131 of the bottom cover panel 13 on top and the protruding portion 142 of the attachment panel 14 under it and screw it to the leg portion 21 of the partition plate 20. According to this, The cushioning material 144 can ensure the airtightness of the screwed portion. Further, even if vibration is applied to the housing 10 when the indoor unit 1 is transported to the installation location, the attachment panel 14 can be firmly held by the partition plate 20 .

以上、本発明について実施形態を用いて説明したが、本発明の技術的範囲は上記実施形態の記載に限定されるものではない。当業者であるならば上記実施形態に加えられる変更もしくは改良も本発明の技術的範囲に含まれる。 Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the description of the above embodiments.
