本発明は、空気調和装置の室外機に関し、特に、室外ファンのファンモータを設置するファンモータ台の取付構造に係るものである。     The present invention relates to an outdoor unit of an air conditioner, and particularly relates to a fan motor base mounting structure for installing a fan motor of an outdoor fan.

従来、空気調和装置の室外機は、特許文献1に示すように、ケーシング内に圧縮機の他、室外熱交換器及び室外ファンが収納されているものがある。     Conventionally, as shown in Patent Document 1, an outdoor unit of an air conditioner includes a casing in which an outdoor heat exchanger and an outdoor fan are housed in a casing.

上記室外機のケーシングは、平面視矩形状に形成されている。該ケーシング内は、鉛直板からなる仕切り板によって、圧縮機や電装品が収納される機械室と、室外熱交換器及び室外ファンが収納される熱交換室とに仕切られている。機械室は、正面、側面及び背面がケーシングの側板によって覆われている。一方、熱交換室は、正面が空気の吹出口が形成されたケーシングの側板によって覆われ、側面及び背面は、開口し、空気の吸込口を形成している。該吸込口には、格子状の網部材が嵌め込まれている。     The casing of the outdoor unit is formed in a rectangular shape in plan view. The inside of the casing is partitioned by a partition plate made of a vertical plate into a machine room in which a compressor and electrical components are stored, and a heat exchange chamber in which an outdoor heat exchanger and an outdoor fan are stored. The machine room is covered with a side plate of the casing at the front, side, and back. On the other hand, the front surface of the heat exchange chamber is covered with a side plate of a casing in which an air outlet is formed, and the side surface and the rear surface are opened to form an air inlet. A lattice-like net member is fitted into the suction port.

上記室外熱交換器は、平面視L字状に形成され、L字の2つの外側面が熱交換室の側面及び背面の開口にそれぞれ対向するように配置されている。上記室外ファンは、上記室外熱交換器の内側に配置されている。また、室外ファンは、熱交換室の正面と背面とに平行に延びるファンモータ台に取り付けられている。ファンモータ台は、下端がケーシングの底板に固定される一方、上端が熱交換室の正面から背面に亘って延びる連結板に固定されている。連結板は、前端部がケーシングの前側の側板に固定される一方、後端部は、室外熱交換器の上端部を前後方向に挟持するように該室外熱交換器の上に載置されている。     The outdoor heat exchanger is formed in an L shape in a plan view, and is arranged so that the two outer surfaces of the L shape face the openings on the side surface and the back surface of the heat exchange chamber, respectively.

ところで、室外ファンの風量が大きくなると、羽根の回転に伴って生じる振動が大きくなる。そのため、室外ファンの回転に伴う振動を低減することが必要となり、ファンモータ台のより強固な固定が望まれる。そこで、連結板の後端部と天板とをネジ止めすることで振動の低減を図ることが考えられる。     By the way, when the air volume of the outdoor fan increases, the vibration generated with the rotation of the blades increases. Therefore, it is necessary to reduce the vibration associated with the rotation of the outdoor fan, and a stronger fixation of the fan motor base is desired. Therefore, it is conceivable to reduce the vibration by screwing the rear end portion of the connecting plate and the top plate.

しかしながら、連結板の後端部は、室外熱交換器に載置されているにすぎず、天板にネジ止めされるまでは左右方向の位置が定まらない。また、連結板と天板とのネジ止めは連結板天板覆い被さった状態で行われるため、連結板のネジ孔と天板の挿通孔との位置合わせが困難となり、取り付け作業に手間取るおそれがあった。 However, the rear end portion of the connecting plate is merely placed on the outdoor heat exchanger, and the position in the left-right direction is not determined until it is screwed to the top plate. In addition, since the screwing of the connecting plate and the top plate is performed with the top plate covering the connecting plate, it is difficult to align the screw hole of the connecting plate and the insertion hole of the top plate, and it takes time for installation work. There was a fear.

On the other hand, the folded portion (32) on the rear side is constituted by two folded pieces (32a, 32a) in which the left and right ends of the rear end portion of the main body portion (31) are folded downward. The two folded piece (32a, 32a) has an upper surface and outer side surface of the support member upon being placed on the rear end of (30b) the outdoor heat exchanger (22), an outdoor heat exchanger (22) It is formed so as to be caught in a corner portion formed by.

このような構成により、支持部材(30b)は、前端部がケーシング(10)の前面に固定される一方、後端部が上記室外熱交換器(22)の上に載置されることによって、ケーシング(10)と室外熱交換器(22)とに架け渡されて支持されている。また、支持部材(30b)は、2つの折り返し片(32a,32a)と切り起こし片(31a)とによって上記室外熱交換器(22)を挟み込むように、該室外熱交換器(22)に載置されている。そのため、支持部材(30b)は、前後方向には移動できないが、左右方向には若干の移動が可能な状態で室外熱交換器(22)に載置されることとなる。     With such a configuration, the support member (30b) has the front end fixed to the front surface of the casing (10), while the rear end is placed on the outdoor heat exchanger (22). It is spanned and supported by the casing (10) and the outdoor heat exchanger (22). The support member (30b) is mounted on the outdoor heat exchanger (22) so as to sandwich the outdoor heat exchanger (22) between the two folded pieces (32a, 32a) and the cut-and-raised piece (31a). Is placed. Therefore, the support member (30b) cannot be moved in the front-rear direction, but is placed on the outdoor heat exchanger (22) in a state where it can be slightly moved in the left-right direction.

また、支持部材(30b)の上記2つの折り返し片(32a,32a)の間には、本体部(31)の後方に突出する突出部(35)が形成されている。突出部(35)は、本体部(31)の後方に延びる延出部(35a)と、該延出部(35a)の後端において下方に折り返された折り返し片(35b)とを有し、L字状の板状に形成されている。折り返し片(35b)は、天板(11)を取り付けると、外側面が天板(11)の背面側の側壁部(11b)の内側面に対向するように形成されている。折り返し片(35b)の中央部分には、後述するボルト(51)が締結されるネジ孔(35c)が形成されている。詳細については後述するが、このような構成により、突出部(35)は、ファンモータ台(30)の支持部材(30b)と天板(11)との取付構造(50)の一部を構成する。     Further, a projecting portion (35) projecting rearward of the main body portion (31) is formed between the two folded pieces (32a, 32a) of the support member (30b). The projecting portion (35) includes an extending portion (35a) extending rearward of the main body portion (31), and a folded piece (35b) folded downward at the rear end of the extending portion (35a). It is formed in an L-shaped plate shape. When the top plate (11) is attached, the folded piece (35b) is formed so that the outer surface faces the inner surface of the side wall portion (11b) on the back side of the top plate (11). A screw hole (35c) to which a later-described bolt (51) is fastened is formed in the central portion of the folded piece (35b). Although the details will be described later, with this configuration, the protrusion (35) constitutes a part of the mounting structure (50) between the support member (30b) of the fan motor base (30) and the top plate (11). To do.

〈ファンモータ台と天板との取付構造〉
図3に示すように、ファンモータ台(30)の支持部材(30b)と天板(11)との取付構造(50)は、ガイド(15)と挿通孔(14)とが形成された天板(11)の背面側の側壁部(11b)と、ネジ孔(35c)が形成された支持部材(30b)の突出部(35)と、ボルト(51)と、座金(52)とを有している。
<Fan motor base and top plate mounting structure>
As shown in FIG. 3, the mounting structure (50) between the support member (30b) of the fan motor base (30) and the top plate (11) has a top formed with a guide (15) and an insertion hole (14). It has a side wall (11b) on the back side of the plate (11), a protrusion (35) of the support member (30b) in which the screw hole (35c) is formed, a bolt (51), and a washer (52). doing.

ガイド(15)は、天板(11)の背面側の側壁部(11b)の一部を内側に切り起こして形成された一対の切り起こし片(15)によって形成されている。一対の切り起こし片(15)は、挿通孔(14)を挟むように形成されている。また、一対の切り起こし片(15)は、左右方向において互いに対向すると共に上下方向において上側ほど互いの間隔が狭くなるように傾斜している。より具体的には、一対の切り起こし片(15)は、上端部の互いの間隔が、支持部材(30b)の突出部(35)の幅と略等しくなる一方、下端部の互いの間隔が、支持部材(30b)の突出部(35)の幅よりも大きくなるように形成されている。     The guide (15) is formed by a pair of cut and raised pieces (15) formed by cutting and raising a part of the side wall (11b) on the back side of the top plate (11). The pair of cut and raised pieces (15) are formed so as to sandwich the insertion hole (14). Further, the pair of cut and raised pieces (15) are inclined so as to face each other in the left-right direction and to be narrower toward each other in the up-down direction. More specifically, in the pair of cut and raised pieces (15), the distance between the upper ends is substantially equal to the width of the protrusion (35) of the support member (30b), while the distance between the lower ends is The support member (30b) is formed so as to be larger than the width of the protrusion (35).

上記支持部材(30b)の突出部(35)は、一対の切り起こし片(15)に挟み込まれている。より具体的には、突出部(35)は、一対の切り起こし片(15)のそれぞれの上端部に当接することにより、一対の切り起こし片(15)の間に挟まっている。また、この状態において、突出部(35)のネジ孔(35c)と天板(11)の挿通孔(14)とは対向している。     The protrusion (35) of the support member (30b) is sandwiched between the pair of cut and raised pieces (15). More specifically, the protrusion (35) is sandwiched between the pair of cut-and-raised pieces (15) by contacting the upper ends of the pair of cut-and-raised pieces (15). In this state, the screw hole (35c) of the projecting portion (35) and the insertion hole (14) of the top plate (11) face each other.

上記ボルト(51)は、座金(52)及び挿通孔(14)に挿通され、該挿通孔(14)に対向するネジ孔(35c)に螺合されている。これにより、ファンモータ台(30)の支持部材(30b)と天板(11)とが固定されている。     The bolt (51) is inserted into the washer (52) and the insertion hole (14), and is screwed into the screw hole (35c) facing the insertion hole (14). Thereby, the support member (30b) and the top plate (11) of the fan motor base (30) are fixed.

〈ファンモータ台の支持部材と天板との取付方法〉
以下、ファンモータ台(30)の支持部材(30b)と天板(11)の取付方法について図4に基づいて説明する。
<Attaching method of fan motor base support member and top plate>
Hereinafter, a method for attaching the support member (30b) and the top plate (11) of the fan motor base (30) will be described with reference to FIG.

まず、室外ファン(23)が取り付けられたファンモータ台(30)が天板(11)のみが組付けられていない状態のケーシング(10)内に設置される。このとき、ファンモータ台(30)の支持部材(30b)は、上述のように、前端部がケーシング(10)の前面に固定される一方、後端部が、2つの折り返し片(32a,32a)と切り起こし片(31a)とによって上記室外熱交換器(22)を挟み込むように、該室外熱交換器(22)の上に載置される。そのため、支持部材(30b)は、前後方向には移動できないが、左右方向には若干の移動が可能な状態となる。     First, the fan motor base (30) to which the outdoor fan (23) is attached is installed in the casing (10) in a state where only the top plate (11) is not assembled. At this time, as described above, the support member (30b) of the fan motor base (30) has the front end portion fixed to the front surface of the casing (10), while the rear end portion has two folded pieces (32a, 32a). ) And the cut-and-raised piece (31a) so that the outdoor heat exchanger (22) is sandwiched between the outdoor heat exchanger (22). Therefore, the support member (30b) cannot move in the front-rear direction, but can move slightly in the left-right direction.

ところで、上述のような状態では、支持部材(30b)の後端部は、室外熱交換器(22)の上に載置されているにすぎないため、左右方向の位置が定まらず、所望の設置位置からずれている可能性が高い。支持部材(30b)の後端部が所望の設置位置からずれると、天板(11)とネジ止めする際に、支持部材(30b)のネジ孔(35c)と天板(11)の挿通孔(14)との位置を合わせる作業が必要となり、手間がかかる。また、支持部材(30b)と天板(11)との固定は支持部材(30b)天板(11)覆い被さった状態で行われるため、支持部材(30b)のネジ孔(35c)と天板(11)の挿通孔(14)との位置合わせが困難となり、取り付け作業に手間取るおそれがある。 By the way, in the state as described above, the rear end portion of the support member (30b) is merely placed on the outdoor heat exchanger (22). There is a high possibility that it is displaced from the installation position. When the rear end of the support member (30b) is displaced from the desired installation position, the screw hole (35c) of the support member (30b) and the insertion hole of the top plate (11) when screwed to the top plate (11) Work to align with (14) is necessary and takes time. The support member and (30b) for fixing the top plate (11) is carried out in a state where the top plate to the support member (30b) is (11) covering overlying the screw hole of the support member (30b) and (35c) Positioning with the insertion hole (14) of the top plate (11) becomes difficult, and there is a risk that it takes time for installation work.

これに対し、本実施形態の取付構造(50)は、天板(11)を側板(12)の上方から下方へ移動させて該側板(12)に組付ける際に、支持部材(30b)の突出部(35)と当接するガイド(15)(一対の切り起こし片(15))によって、支持部材(30b)の後端部を、上記ネジ孔(35c)と上記挿通孔(14)とが対向する設置位置まで導くこととしている。そのため、天板(11)を側板(12)の上方から下方へ移動させて該側板(12)に組付けるだけで、支持部材(30b)の後端部がガイド(15)によって設置位置まで導かれ、上記ネジ孔(35c)と上記挿通孔(14)とが対向する。     On the other hand, the mounting structure (50) of the present embodiment allows the top plate (11) to move downward from above the side plate (12) to be attached to the side plate (12). By means of the guide (15) (a pair of cut and raised pieces (15)) in contact with the projecting portion (35), the screw hole (35c) and the insertion hole (14) are connected to the rear end of the support member (30b). It is supposed to lead to the opposite installation position. Therefore, the rear end of the support member (30b) is guided to the installation position by the guide (15) only by moving the top plate (11) from the upper side to the lower side of the side plate (12) and assembling it to the side plate (12). The screw hole (35c) and the insertion hole (14) face each other.

具体的には、図4(a)に示すように、天板(11)が側板(12)に組付けられる前の状態において、支持部材(30b)のネジ孔(35c)と天板(11)の挿通孔(14)との左右方向の位置がずれている場合がある。図4(a)では、支持部材(30b)の後端部が、ネジ孔(35c)と挿通孔(14)とが対向する設置位置から距離dだけ左側にずれている。このような場合には、そのまま天板(11)を下方に移動させると、ガイド(15)を構成する一対の切り起こし片(15)のうちの左側の切り起こし片(15)が、支持部材(30b)の突出部(35)の左端部に当接する(図4(b)参照)。     Specifically, as shown in FIG. 4A, in the state before the top plate (11) is assembled to the side plate (12), the screw hole (35c) of the support member (30b) and the top plate (11 ) May be misaligned with the insertion hole (14) in the left-right direction. In FIG. 4A, the rear end portion of the support member (30b) is shifted to the left by a distance d from the installation position where the screw hole (35c) and the insertion hole (14) face each other. In such a case, when the top plate (11) is moved downward as it is, the left cut-and-raised piece (15) of the pair of cut-and-raised pieces (15) constituting the guide (15) becomes the support member. It contacts the left end of the protrusion (35) of (30b) (see FIG. 4 (b)).

ここで、一対の切り起こし片(15)は、左右方向において互いに対向すると共に上下方向において上側ほど互いの間隔が狭くなるように傾斜している。つまり、左側の切り起こし片(15)は、下端から上端に向かう程、右側に位置するように傾斜している。そのため、左側の切り起こし片(15)が突出部(35)の左端部に当接したまま、天板(11)をさらに下方に移動させると、突出部(35)が左側の切り起こし片(15)によって右側へ押され、突出部(35)が形成された支持部材(30b)の後端部が右側へ移動する(図4(b)参照)。     Here, the pair of cut-and-raised pieces (15) are inclined so as to face each other in the left-right direction and become narrower toward each other in the up-down direction. That is, the left cut and raised piece (15) is inclined so as to be positioned on the right side from the lower end toward the upper end. Therefore, when the top plate (11) is moved further downward while the left cut-and-raised piece (15) is in contact with the left end of the protruding portion (35), the protruding portion (35) is moved to the left-cut and raised piece ( 15), the rear end of the support member (30b) on which the protrusion (35) is formed is moved to the right by being pushed to the right (see FIG. 4 (b)).

支持部材(30b)の後端部は、突出部(35)が一対の切り起こし片(15)に挟み込まれるまで右側へ移動する。上述の場合、支持部材(30b)の後端部は、突出部(35)の右端部が右側の切り起こし片(15)に当接するまで右側へ移動する(図4(c)参照)。このようにして、天板(11)が側板(12)に組付けられると共に、突出部(35)が一対の切り起こし片(15)の間に挟まるように支持部材(30b)の後端部が移動して所望の設置位置に至る。その結果、突出部(35)のネジ孔(35c)と天板(11)の挿通孔(14)とが対向する。     The rear end portion of the support member (30b) moves to the right until the projecting portion (35) is sandwiched between the pair of cut and raised pieces (15). In the case described above, the rear end portion of the support member (30b) moves to the right side until the right end portion of the projecting portion (35) contacts the right cut and raised piece (15) (see FIG. 4C). In this way, the top plate (11) is assembled to the side plate (12), and the rear end of the support member (30b) so that the protruding portion (35) is sandwiched between the pair of cut and raised pieces (15). Moves to the desired installation position. As a result, the screw hole (35c) of the protrusion (35) and the insertion hole (14) of the top plate (11) face each other.

その後、ボルト(51)を座金(52)及び挿通孔(14)に挿通し、該挿通孔(14)に対向するネジ孔(35c)と螺合させる。これにより、ファンモータ台(30)の支持部材(30b)と天板(11)とが固定される。     Thereafter, the bolt (51) is inserted into the washer (52) and the insertion hole (14), and screwed into the screw hole (35c) facing the insertion hole (14). Thereby, the support member (30b) and the top plate (11) of the fan motor base (30) are fixed.

このようにして天板(11)を側板(12)の上方から下方へ移動させて該側板(12)に組付けるだけで、容易にネジ孔(35c)と挿通孔(14)とが対向する。そのため、位置合わせ作業を行うことなく、ボルト(51)を締結することができる。     In this way, the screw hole (35c) and the insertion hole (14) easily face each other simply by moving the top plate (11) from the upper side to the lower side of the side plate (12) and assembling the side plate (12). . Therefore, the bolt (51) can be fastened without performing an alignment operation.

−実施形態の効果−
本実施形態によれば、支持部材(30b)の室外熱交換器(22)に載置された後端部に、室外熱交換器(22)の後方へ突出してネジ孔(35c)が形成された突出部(35)を設ける一方、ケーシング(10)の天板(11)に、該天板(11)を側板(12)に組付ける際に、突出部(35)と当接して支持部材(30b)の後端部をネジ孔(35c)と挿通孔(14)とが対向する設置位置まで導くガイド(15)を設けることとした。これにより、天板(11)を側板(12)に組付けるために下方へ移動させるだけで、突出部(35)に形成されたネジ孔(35c)と天板(11)に形成された挿通孔(14)とを対向させることができる。従って、位置合わせ作業を別途行うことなく、雄ネジ(51)を締結して、ファンモータ台(30)の支持部材(30b)と天板(11)とを容易に固定することができ、取り付け作業を容易化することができる。また、このように、ファンモータ台(30)の支持部材(30b)と天板(11)とを固定することにより、室外ファン(23)の回転に伴う振動を低減することができる。
-Effect of the embodiment-
According to the present embodiment, a screw hole (35c) is formed at the rear end of the support member (30b) placed on the outdoor heat exchanger (22) so as to protrude rearward of the outdoor heat exchanger (22). When the top plate (11) is assembled to the side plate (12) on the top plate (11) of the casing (10), the support member comes into contact with the projection (35). A guide (15) for guiding the rear end of (30b) to an installation position where the screw hole (35c) and the insertion hole (14) face each other is provided. Thus, the screw hole (35c) formed in the projecting portion (35) and the insertion formed in the top plate (11) are simply moved downward to assemble the top plate (11) to the side plate (12). The hole (14) can be opposed. Therefore, the male screw (51) can be fastened and the support member (30b) and the top plate (11) of the fan motor base (30) can be easily fixed without performing the positioning work separately. Work can be facilitated. Further, by fixing the support member (30b) and the top plate (11) of the fan motor base (30) in this way, vibration associated with the rotation of the outdoor fan (23) can be reduced.

また、本実施形態によれば、ガイド(15)を、天板(11)の後端部に形成され、左右方向において互いに対向すると共に上下方向において上側ほど互いの間隔が狭くなるように傾斜した一対の板状片(15,15)によって構成することとした。これにより、支持部材(30b)の後端部を設置位置まで導くガイド(15)を、上述のような一対の板状片(15,15)によって容易に構成することができる。     Further, according to the present embodiment, the guide (15) is formed at the rear end portion of the top plate (11) and is opposed to each other in the left-right direction and inclined so that the distance between the guides (15) becomes narrower toward the upper side in the vertical direction A pair of plate-like pieces (15, 15) is used. Thereby, the guide (15) which guides the rear end of the support member (30b) to the installation position can be easily configured by the pair of plate-like pieces (15, 15) as described above.

また、本実施形態によれば、一対の板状片(15,15)を、天板(11)の一部を切り起こして形成することにより、容易に構成することができる。     Further, according to the present embodiment, the pair of plate-like pieces (15, 15) can be easily configured by cutting and raising a part of the top plate (11).

《その他の実施形態》
上記実施形態では、一対の板状片(15,15)は、天板(11)の背面側の側壁部(11b)に形成されていたが、例えば、本体部(11a)の後端部に形成することとしてもよい。この場合であっても、一対の板状片(15,15)を、左右方向において互いに対向すると共に上下方向において上側ほど互いの間隔が狭くなるように傾斜させて形成することにより、上記実施形態と同様の効果を奏することができる。
