Description

本発明は、送風機を支持する支持装置を備えた空気調和機の室外機に関する。 The present invention relates to an outdoor unit of an air conditioner provided with a support device for supporting a blower.

従来から、空気調和機の室外機（以下、室外機という）は、外気と冷媒との熱交換を行う熱交換器と、モータ及びファンを有する送風機とを備える。送風機は、熱交換器へ効率的に空気が供給されるように、室外機の筐体の予め設定された高さに金属製の支持装置により設置される。室外機において、モータ外郭を支持装置に係合させることで送風機を支持装置に固定したものがある（例えば、特許文献１参照）。特許文献１の室外機において、モータと一体に取付部が設けられており、取付部に設けられた引っ掛け部が直接又は防振部材を介在させて、支持部材に設けられた係合部に係合される。 Conventionally, an outdoor unit of an air conditioner (hereinafter referred to as an outdoor unit) includes a heat exchanger that exchanges heat between the outside air and a refrigerant, and a blower having a motor and a fan. The blower is installed by a metal support at a preset height of the housing of the outdoor unit so that air is efficiently supplied to the heat exchanger. In some outdoor units, the blower is fixed to the support device by engaging the outer shell of the motor with the support device (see, for example, Patent Document 1). In the outdoor unit of Patent Document 1, a mounting portion is provided integrally with the motor, and the hooking portion provided on the mounting portion engages with the engaging portion provided on the support member directly or by interposing a vibration isolator member. Will be combined.

特開２０１２−１３３９０号公報Japanese Unexamined Patent Publication No. 2012-13390

しかしながら、特許文献１の送風機において、引っ掛け部はモータと一体の取付部に設けられているため、このような取付部を送風機に設けようとすると、モータの構造を変更する必要が生じる。また、取付部が適用されてモータの構造が変更されると、一般的な送風機のモータとの互換性が無くなり、後に仕様の変更が必要となった場合にモータに大幅な構造変更が生じ得る。 However, in the blower of Patent Document 1, since the hooking portion is provided in the mounting portion integrated with the motor, if such a mounting portion is to be provided in the blower, it is necessary to change the structure of the motor. In addition, if the mounting part is applied and the structure of the motor is changed, compatibility with the motor of a general blower will be lost, and if the specifications need to be changed later, the structure of the motor may be significantly changed. ..

また、送風機のモータが支持装置に取り付けられる構成では、モータ外郭の部材と支持装置の部材との組み合わせを考慮する必要がある。例えば、モータ外郭と支持装置とは異なる種類の金属材料で構成されることがある。この場合、特許文献１のように取付部が支持装置に係合する構成では、取付部と支持装置との間に塩水等の腐食媒体が付着すると、異種材料間の電位差により電子の流れが生じ、金属のイオン化が促進されて取付部と支持装置との接触部に腐食が生じる。モータの取付部に腐食が生じた場合、モータの固定の安定性が低下し、振動が発生して熱交換器の熱交換効率が低下することがある。このため、モータ外郭の部材と支持装置の部材との組み合わせの自由度を高めるためには、腐食を抑制することが望まれる。 Further, in the configuration in which the motor of the blower is attached to the support device, it is necessary to consider the combination of the member of the outer shell of the motor and the member of the support device. For example, the outer shell of the motor and the support device may be composed of different types of metal materials. In this case, in the configuration in which the mounting portion engages with the support device as in Patent Document 1, when a corrosive medium such as salt water adheres between the mounting portion and the support device, electron flow occurs due to a potential difference between different materials. , Ionization of metal is promoted and corrosion occurs at the contact part between the mounting part and the support device. If the mounting portion of the motor is corroded, the stability of fixing the motor may be reduced, and vibration may be generated to reduce the heat exchange efficiency of the heat exchanger. Therefore, in order to increase the degree of freedom in combining the member of the outer shell of the motor and the member of the support device, it is desired to suppress corrosion.

本発明は、上記のような課題を解決するためになされたもので、モータと支持装置との組み合わせの自由度が高い空気調和機の室外機を提供することを目的とする。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an outdoor unit of an air conditioner having a high degree of freedom in combination of a motor and a support device.

本発明に係る空気調和機の室外機は、モータを有する送風機と、前記送風機を支持する支持装置と、前記モータと前記支持装置との間に設けられ、背面に、前記支持装置と係合する爪部を有する絶縁部材とを備え、前記モータは、前記絶縁部材に固定され、前記絶縁部材を介して前記支持装置に支持される。
また、本発明に係る空気調和機の室外機は、モータを有する送風機と、前記送風機を支持する支持装置と、前記モータと前記支持装置との間に設けられ、前記支持装置と係合する突起を有する絶縁部材とを備え、前記モータは、前記絶縁部材に固定され、前記絶縁部材を介して前記支持装置に支持されるものであり、前記支持装置には、開口部が形成されており、前記絶縁部材は前記開口部に配置され、前記突起は、前記絶縁部材の外周部に設けられており、前記絶縁部材には、前記モータが挿入される絶縁開口部が形成されている。 The outdoor unit of the air conditioner according to the present invention is provided between a blower having a motor, a support device for supporting the blower, and the motor and the support device, and engages with the support device on the back surface. The motor includes an insulating member having a claw portion, and the motor is fixed to the insulating member and supported by the support device via the insulating member.
Further, the outdoor unit of the air conditioner according to the present invention is a protrusion provided between a blower having a motor, a support device for supporting the blower, and the motor and the support device, and engaging with the support device. The motor is fixed to the insulating member and supported by the support device via the insulating member, and the support device is formed with an opening. The insulating member is arranged in the opening, the protrusion is provided on the outer peripheral portion of the insulating member, and the insulating member is formed with an insulating opening into which the motor is inserted.

本発明の空気調和機の室外機によれば、絶縁部材を介してモータが支持装置に固定されることにより、モータと支持装置とを絶縁でき、モータと支持装置とを異種金属で構成した場合でも腐食を抑制できる。また、絶縁部材の突起が支持装置と係合する構成により、支持部材へモータを支持させるためにモータ形状を変更する必要がないので、一般的なモータとの互換性を確保できる。したがって、モータと支持装置との組み合わせの自由度が高い空気調和機の室外機を提供することができる。 According to the outdoor unit of the air conditioner of the present invention, the motor and the support device can be insulated by fixing the motor to the support device via an insulating member, and the motor and the support device are made of different metals. But corrosion can be suppressed. Further, since the protrusion of the insulating member engages with the support device, it is not necessary to change the shape of the motor in order to support the motor on the support member, so compatibility with a general motor can be ensured. Therefore, it is possible to provide an outdoor unit of an air conditioner having a high degree of freedom in combining a motor and a support device.

図２は、本発明の実施の形態１に係る支持装置の正面図である。図中、矢印Ｘ方向は支持装置９の幅方向を表し、矢印Ｚ方向は支持装置９の高さ方向を表す。以下、支持装置９の高さ方向及び幅方向は、図１に示される室外機１００の高さ方向及び幅方向とそれぞれ一致するものとして説明する。 FIG. 2 is a front view of the support device according to the first embodiment of the present invention. In the figure, the arrow X direction represents the width direction of the support device 9, and the arrow Z direction represents the height direction of the support device 9. Hereinafter, the height direction and the width direction of the support device 9 will be described as being coincident with the height direction and the width direction of the outdoor unit 100 shown in FIG. 1, respectively.

図１及び図２に示されるように、支持装置９は、ねじ等の固定部材により筐体１に対して固定されており、支持装置９を介して、２台の送風機４が筐体１に取り付けられ、熱交換器３の前面に上下に配置される。支持装置９は、強度を確保するために、例えば鉄等の金属で構成される。支持装置９は、筐体１の底面１ａに設置され、室外機１００の高さ方向（矢印Ｚ方向）に延びる２本の支柱１１と、２本の支柱１１に渡って設けられた箱状の（図３参照）モータ固定部１２とを有する。モータ固定部１２は高さ方向（矢印Ｚ方向）に２つ設けられており、各モータ固定部１２には各送風機４のモータ６が固定される。 As shown in FIGS. 1 and 2, the support device 9 is fixed to the housing 1 by a fixing member such as a screw, and two blowers 4 are attached to the housing 1 via the support device 9.

(See FIG. 3) It has a motor fixing portion 12. Two motor fixing portions 12 are provided in the height direction (arrow Z direction), and the motor 6 of each blower 4 is fixed to each motor fixing portion 12.

図３は、本発明の実施の形態１に係るモータ固定部にモータを取り付ける前の状態を示す分解斜視図である。図４は、本発明の実施の形態１に係るモータ固定部に絶縁部材を固定した状態を示す斜視図である。図１〜図４に基づき、送風機４と支持装置９との取り付け構造について説明する。 FIG. 3 is an exploded perspective view showing a state before the motor is attached to the motor fixing portion according to the first embodiment of the present invention. FIG. 4 is a perspective view showing a state in which the insulating member is fixed to the motor fixing portion according to the first embodiment of the present invention. The mounting structure of the blower 4 and the support device 9 will be described with reference to FIGS. 1 to 4.

モータ固定部１２の前面１６には、略円形状の開口部１３と、支持装置９の幅方向（矢印Ｘ方向）に延びるスリット状の４つの差込穴１４（係合部）が形成されている。開口部１３には、送風機４のモータ６が挿入される。４つの差込穴１４は開口部１３の周囲に設けられている。具体的には、モータ固定部１２の前面１６において開口部１３の外側の左上と、左下と、右上と、右下とに差込穴１４が形成されている。図３において、差込穴１４はモータ固定部１２の前面１６の４つの角部にそれぞれ設けられている。 A substantially circular opening 13 and four slit-shaped insertion holes 14 (engagement portions) extending in the width direction (arrow X direction) of the support device 9 are formed on the front surface 16 of the motor fixing portion 12. There is. The motor 6 of the blower 4 is inserted into the opening 13. The four insertion holes 14 are provided around the opening 13. Specifically, on the front surface 16 of the motor fixing portion 12, insertion holes 14 are formed on the outer upper left, lower left, upper right, and lower right of the opening 13. In FIG. 3, the insertion holes 14 are provided at the four corners of the front surface 16 of the motor fixing portion 12, respectively.

またモータ６は、円柱形状のモータ本体３１と、モータ軸３３と、モータ本体３１に設けられた４つの脚部３４とを有している。モータ軸３３はモータ本体３１に回転自在に支持されており、モータ軸３３にはファン５（図１参照）が取り付けられる。各脚部３４は、例えばアルミニウム等の金属から成り、モータ本体３１の外周面３２から半径方向外側へ向かって放射状に設けられている。各脚部３４には、奥行き方向（矢印Ｙ方向）に貫通した脚部ねじ孔３５が形成されており、脚部ねじ孔３５に固定ねじ４０が通される。 Further, the motor 6 has a cylindrical motor body 31, a motor shaft 33, and four legs 34 provided on the motor body 31. The motor shaft 33 is rotatably supported by the motor body 31, and a fan 5 (see FIG. 1) is attached to the motor shaft 33. Each leg 34 is made of a metal such as aluminum, and is provided radially outward from the outer peripheral surface 32 of the motor body 31. Each leg 34 is formed with a leg screw hole 35 penetrating in the depth direction (arrow Y direction), and a fixing screw 40 is passed through the leg screw hole 35.

また室外機１００は、送風機４のモータ６とモータ固定部１２とを電気的に絶縁する２つの絶縁部材２０を備えている。絶縁部材２０は、モータ６とは別体として形成されており、例えば樹脂等の絶縁性に優れた部材から成る。各絶縁部材２０は、モータ６とモータ固定部１２との間に配置され、２つの絶縁部材２０を介して、モータ６の脚部３４がモータ固定部１２に固定される。 Further, the outdoor unit 100 includes two insulating members 20 that electrically insulate the motor 6 of the blower 4 and the motor fixing portion 12. The insulating member 20 is formed as a separate body from the motor 6, and is made of, for example, a member having excellent insulating properties such as resin. Each insulating member 20 is arranged between the motor 6 and the motor fixing portion 12, and the leg portion 34 of the motor 6 is fixed to the motor fixing portion 12 via the two insulating members 20.

各絶縁部材２０は、全体としてほぼ直方体形状を有している。各絶縁部材２０は、絶縁本体部２１と、絶縁本体部２１の背面に設けられた２つの爪部２２とを有している。爪部２２は、モータ固定部１２に係合する突起の一例である。 Each insulating member 20 has a substantially rectangular parallelepiped shape as a whole. Each insulating member 20 has an insulating main body 21 and two claws 22 provided on the back surface of the insulating main body 21. The claw portion 22 is an example of a protrusion that engages with the motor fixing portion 12.

絶縁本体部２１は、正面視で高さ方向（矢印Ｚ方向）に延びる長方形状をしており、一定以上の厚さに形成されている。ここで、絶縁本体部２１の厚さは、モータ６とモータ固定部１２とが近接する脚部３４周辺で、脚部３４とモータ固定部１２との電気的な絶縁が確保できる厚さであればよい。また、絶縁本体部２１の前面側から見ることを正面視という。 The insulating main body 21 has a rectangular shape extending in the height direction (arrow Z direction) when viewed from the front, and is formed to have a thickness of a certain value or more. Here, the thickness of the insulating main body portion 21 is such that the electric insulation between the leg portion 34 and the motor fixing portion 12 can be ensured around the leg portion 34 in which the motor 6 and the motor fixing portion 12 are close to each other. Just do it. Further, viewing from the front side of the insulating main body portion 21 is referred to as front view.

各絶縁本体部２１の前面には、高さ方向（矢印Ｚ方向）に２つのねじ穴２３が形成されている。２つのねじ穴２３の間隔は、上下に隣接した脚部３４の脚部ねじ孔３５の間隔とほぼ一致している。絶縁本体部２１は複数の脚部３４に渡って設けられる。すなわち、複数の脚部３４が１つの絶縁本体部２１を共有する。これにより、脚部３４を介したモータ固定部１２へのモータ６の固定のための部品が少なくてすむ。 Two screw holes 23 are formed on the front surface of each insulating main body 21 in the height direction (arrow Z direction). The distance between the two screw holes 23 is substantially the same as the distance between the leg screw holes 35 of the vertically adjacent legs 34. The insulating main body 21 is provided over a plurality of legs 34. That is, the plurality of legs 34 share one insulating main body 21. As a result, the number of parts for fixing the motor 6 to the motor fixing portion 12 via the leg portion 34 can be reduced.

絶縁本体部２１ごとに設けられた２つの爪部２２は、絶縁本体部２１の背面に対し傾斜するように下方へ延び、２つの爪部２２の一方は絶縁本体部２１の背面の上部に設けられ、他方は絶縁本体部２１の背面の下部に設けられている。 The two claws 22 provided for each of the insulating main body 21 extend downward so as to be inclined with respect to the back surface of the insulating main body 21, and one of the two claws 22 is provided on the upper part of the back surface of the insulating main body 21. The other is provided at the lower part of the back surface of the insulating main body 21.

一方の絶縁部材２０は、２つの爪部２２が、モータ固定部１２に形成されている右側の２つの差込穴１４にそれぞれ差し込まれ係合することにより、開口部１３の右側に固定される。他方の絶縁部材２０は、２つの爪部２２が、モータ固定部１２に形成されている左側の２つの差込穴１４にそれぞれ差し込まれ係合することにより、開口部１３の左側に固定される。モータ固定部１２に２つの絶縁部材２０が固定された状態で、開口部１３にモータ本体３１が奥行き方向（矢印Ｙ方向）に挿入され、４つの固定ねじ４０によって２つの各絶縁部材２０に４つの脚部３４が締結される。このようにして、モータ６が２つの絶縁部材２０を介してモータ固定部１２に固定され支持される。そして、モータ６のモータ軸３３にファン５が取り付けられる。 One insulating member 20 is fixed to the right side of the opening 13 by inserting and engaging the two claws 22 into the two insertion holes 14 on the right side formed in the motor fixing portion 12. .. The other insulating member 20 is fixed to the left side of the opening 13 by inserting and engaging the two claws 22 into the two insertion holes 14 on the left side formed in the motor fixing portion 12. .. With the two insulating members 20 fixed to the motor fixing portion 12, the motor body 31 is inserted into the opening 13 in the depth direction (arrow Y direction), and four fixing screws 40 are used to connect the two insulating members 20 to each of the two insulating members 20. The two legs 34 are fastened. In this way, the motor 6 is fixed and supported by the motor fixing portion 12 via the two insulating members 20. Then, the fan 5 is attached to the motor shaft 33 of the motor 6.

図５は、本発明の実施の形態１に係るモータ固定部にモータを取り付けた状態を示す正面図である。ここで、支持装置９の幅方向（矢印Ｘ方向）において、絶縁部材２０同士の間隔Ｗｉはモータ本体３１の外径Ｄｍと同程度であり、開口部１３の開口幅Ｗｏはモータ本体３１の外径Ｄｍよりも大きくなるように設定されている。モータ本体３１は、左側の絶縁部材２０と右側の絶縁部材２０との隙間から開口部１３に挿入され、開口部１３のほぼ中央に配置される。このような構成により、モータ本体３１の外郭とモータ固定部１２とが異なる種類の金属から成る場合でも、モータ本体３１の外周面３２と開口部１３の縁部とが離間しているため、異種金属接触による腐食の発生を防止できる。 FIG. 5 is a front view showing a state in which the motor is attached to the motor fixing portion according to the first embodiment of the present invention. Here, in the width direction of the support device 9 (arrow X direction), the distance Wi between the insulating members 20 is about the same as the outer diameter Dm of the motor body 31, and the opening width Wo of the opening 13 is outside the motor body 31. It is set to be larger than the diameter Dm. The motor body 31 is inserted into the opening 13 through a gap between the insulating member 20 on the left side and the insulating member 20 on the right side, and is arranged substantially in the center of the opening 13. With such a configuration, even when the outer shell of the motor body 31 and the motor fixing portion 12 are made of different types of metal, the outer peripheral surface 32 of the motor body 31 and the edge portion of the opening 13 are separated from each other, so that they are different. It is possible to prevent the occurrence of corrosion due to metal contact.

さらに、開口部１３の下側の縁部には切り欠き部１５が形成されている。このため、モータ本体３１の外周面３２と開口部１３の縁部との距離は、切り欠き部１５が形成された領域の距離Ｌ１において、切り欠き部１５が形成されていない領域の距離Ｌ２よりも大きくなっている。このような構成により、モータ本体３１の外周面３２又は開口部１３の縁部に付着した水滴が重力によって開口部１３の下側の位置に移動した場合でも、外周面３２と開口部１３の縁部とが水滴でブリッジされることを回避できる。 Further, a notch 15 is formed at the lower edge of the opening 13. Therefore, the distance between the outer peripheral surface 32 of the motor body 31 and the edge of the opening 13 is greater than the distance L2 in the region where the notch 15 is formed in the distance L1 in the region where the notch 15 is formed. Is also getting bigger. With such a configuration, even when water droplets adhering to the outer peripheral surface 32 of the motor body 31 or the edge of the opening 13 move to a lower position of the opening 13 due to gravity, the edge of the outer peripheral surface 32 and the opening 13 It is possible to prevent the part from being bridged by water droplets.

なお、爪部２２及び差込穴１４を設ける位置及び数は特に限定されない。モータ６のがたつきを抑え、安定してモータ固定部１２に固定するためには、爪部２２と差込穴１４が、開口部１３の周方向に均等に配置されているのが好ましい。また、爪部２２と差込穴１４の数が多い方が、安定性が増す。 The position and number of the claws 22 and the insertion holes 14 are not particularly limited. In order to suppress rattling of the motor 6 and stably fix it to the motor fixing portion 12, it is preferable that the claw portion 22 and the insertion hole 14 are evenly arranged in the circumferential direction of the opening 13. Further, the larger the number of the claws 22 and the insertion holes 14, the higher the stability.

また、爪部２２と差込穴１４とか係合する場合について例示したが、絶縁部材２０とモータ固定部１２に、互いに嵌合する凹凸形状が設けられていればよい。また、モータ６の脚部３４が絶縁部材２０にねじ固定される場合について例示したが、別体として形成された絶縁部材２０とモータ６とが固定できれば、どのような固定方法が採用されてもよい。 Further, although the case where the claw portion 22 and the insertion hole 14 are engaged with each other has been illustrated, the insulating member 20 and the motor fixing portion 12 may be provided with an uneven shape that fits each other. Further, although the case where the leg portion 34 of the motor 6 is screw-fixed to the insulating member 20 has been illustrated, any fixing method may be adopted as long as the insulating member 20 formed as a separate body and the motor 6 can be fixed. good.

以上のように、実施の形態１において、空気調和機の室外機１００は、支持装置９と係合する突起（例えば爪部２２）を有する絶縁部材２０を備え、モータ６は、絶縁部材２０に固定され、絶縁部材２０を介して支持装置９に固定されている。これにより、絶縁部材２０を介してモータ６が支持装置９に固定されることにより、モータ６と支持装置９とを絶縁でき、モータ６と支持装置９とを異種金属で構成した場合でも腐食を抑制できる。また、従来のようにモータと一体に取付部が設けられる構成とは異なり、実施の形態１の室外機１００では、絶縁部材２０の突起が支持装置９と係合する。このため、従来のように支持部材へモータを支持させるためにモータ形状を変更する必要がなく、一般的なモータとの互換性を確保できる。したがって、モータ６と支持装置９との組み合わせの自由度が高い空気調和機の室外機１００を提供することができる。 As described above, in the first embodiment, the outdoor unit 100 of the air conditioner includes an insulating member 20 having a protrusion (for example, a claw portion 22) that engages with the support device 9, and the motor 6 is attached to the insulating member 20. It is fixed and fixed to the support device 9 via the insulating member 20. As a result, the motor 6 is fixed to the support device 9 via the insulating member 20, so that the motor 6 and the support device 9 can be insulated from each other, and even when the motor 6 and the support device 9 are made of different metals, corrosion is caused. Can be suppressed. Further, unlike the conventional configuration in which the mounting portion is provided integrally with the motor, in the outdoor unit 100 of the first embodiment, the protrusion of the insulating member 20 engages with the support device 9. Therefore, it is not necessary to change the shape of the motor in order to support the motor on the support member as in the conventional case, and compatibility with a general motor can be ensured. Therefore, it is possible to provide the outdoor unit 100 of the air conditioner having a high degree of freedom in combining the motor 6 and the support device 9.

また支持装置９には、突起（爪部２２）と係合される差込穴１４が形成されている。これにより、モータ６が固定された絶縁部材２０を、爪部２２を差込穴１４に差し込むことにより支持装置９に固定でき、また、差込穴１４から爪部２２を抜き取ることで取り外すことができる。したがって、モータ６と支持装置９との組み合わせによらず支持装置９に対して容易に着脱できる。 Further, the support device 9 is formed with an insertion hole 14 that is engaged with the protrusion (claw portion 22). As a result, the insulating member 20 to which the motor 6 is fixed can be fixed to the support device 9 by inserting the claw portion 22 into the insertion hole 14, and can be removed by removing the claw portion 22 from the insertion hole 14. can. Therefore, it can be easily attached to and detached from the support device 9 regardless of the combination of the motor 6 and the support device 9.

また支持装置９には、モータ６が挿入される開口部１３が形成されており、絶縁部材２０は、支持装置９において開口部１３の外側に複数配置される。これにより、絶縁部材２０と支持装置９との固定位置を複数箇所に分散させることができるため、モータ６を挿入するための開口を確保しつつ、モータ６を複数箇所で安定的に固定することができる。 Further, the support device 9 is formed with an opening 13 into which the motor 6 is inserted, and a plurality of insulating members 20 are arranged outside the opening 13 in the support device 9. As a result, the fixing positions of the insulating member 20 and the support device 9 can be dispersed in a plurality of places, so that the motor 6 can be stably fixed at a plurality of places while securing an opening for inserting the motor 6. Can be done.

また、直方体形状の絶縁部材２０は、従来のようにモータ６と一体的に設けられる取付部と比べて、単純な形状であるので、製造が容易となる。 Further, since the rectangular parallelepiped-shaped insulating member 20 has a simpler shape than the mounting portion provided integrally with the motor 6 as in the conventional case, it is easy to manufacture.

また、脚部３４は絶縁部材２０の前面に固定され、突起（爪部２２）は、絶縁部材２０の背面に設けられている。これにより、絶縁部材２０の厚さ分、支持装置９と脚部３４との距離が確保されるため、支持装置９と脚部３４とが水滴によりブリッジされるのを防止でき、支持装置９及び脚部３４の腐食を抑制することができる。 Further, the leg portion 34 is fixed to the front surface of the insulating member 20, and the protrusion (claw portion 22) is provided on the back surface of the insulating member 20. As a result, the distance between the support device 9 and the leg portion 34 is secured by the thickness of the insulating member 20, so that it is possible to prevent the support device 9 and the leg portion 34 from being bridged by water droplets, and the support device 9 and the leg portion 34 can be prevented from being bridged. Corrosion of the leg portion 34 can be suppressed.

FIG. 9 is an exploded perspective view showing a state before the motor is attached to the motor fixing portion according to the fourth embodiment of the present invention. FIG. 10 is a perspective view showing a state in which the motor is attached to the motor fixing portion according to the fourth embodiment of the present invention. FIG. 11 is an explanatory view showing a method of fixing the motor and the insulating member according to the fourth embodiment of the present invention. The fourth embodiment is different from the first embodiment in that an insulating member 20c for wrapping the leg portion 34 is provided for each leg portion 34. Hereinafter, in the fourth embodiment, items not particularly described will be the same as those in the first embodiment, and the same functions and configurations will be described using the same reference numerals.

実施の形態４では、絶縁部材２０ｃは４つ設けられている。図９〜図１１の例では、直方体の絶縁本体部２１ｃに形成された収容凹部２５ｃに脚部３４が挿入されることにより、脚部４３の外面が絶縁本体部２１ｃに覆われる。各絶縁本体部２１ｃの前面には、ねじ穴２３ｃが１つ形成されている。また、各絶縁本体部２１ｃの背面には、背面に対して傾斜するように下方へ延びる爪部２２ｃが１つ設けられている。 In the fourth embodiment, four insulating members 20c are provided. In the examples of FIGS. 9 to 11, the outer surface of the leg portion 43 is covered with the insulating main body portion 21c by inserting the leg portion 34 into the accommodating recess 25c formed in the insulating main body portion 21c of the rectangular parallelepiped. One screw hole 23c is formed on the front surface of each insulating main body 21c. Further, on the back surface of each insulating main body portion 21c, one claw portion 22c extending downward so as to be inclined with respect to the back surface is provided.

差込穴１４ｃは、モータ固定部１２の前面１６に、開口部１３を囲むように４つ設けられている。各差込穴１４ｃは、例えば、開口部１３の接線方向に延びるスリット状に形成されている。 Four insertion holes 14c are provided on the front surface 16 of the motor fixing portion 12 so as to surround the opening 13. Each insertion hole 14c is formed in a slit shape extending in the tangential direction of the opening 13, for example.

絶縁部材２０ｃと各脚部３４との固定方法は、固定ねじ４０によるねじ固定に限らず、圧入固定、接着、あるいはスナップリングを用いた固定等、適宜選択できる。例えば、圧入固定では、収容凹部２５ｃの厚みが脚部３４の厚み以下に形成され、収容凹部２５ｃの弾性により収容凹部２５ｃの対向面で脚部３４を挟んで押圧することにより形成される。また、脚部３４を収容凹部２５ｃに挿入し易くするために、各脚部３４の先端は、面取り等により先細り形状に形成されてもよい（図１１参照）。モータ６の各脚部３４に各絶縁部材２０ｃが固定されて、爪部２２ｃが差込穴１４ｃに差し込まれ係合されることにより、モータ６がモータ固定部１２に固定される。 The fixing method of the insulating member 20c and each leg 34 is not limited to screw fixing with the fixing screw 40, and can be appropriately selected such as press-fit fixing, adhesion, or fixing using a snap ring. For example, in press-fitting and fixing, the thickness of the accommodating recess 25c is formed to be equal to or less than the thickness of the leg portion 34, and the leg portion 34 is sandwiched and pressed by the elasticity of the accommodating recess 25c on the facing surface of the accommodating recess 25c. Further, in order to facilitate the insertion of the leg portion 34 into the accommodating recess 25c, the tip of each leg portion 34 may be formed in a tapered shape by chamfering or the like (see FIG. 11). Each insulating member 20c is fixed to each leg portion 34 of the motor 6, and the claw portion 22c is inserted into the insertion hole 14c and engaged with the motor 6 to fix the motor 6 to the motor fixing portion 12.

以上のように、実施の形態４においても、実施の形態１の場合と同様に、モータと支持装置との組み合わせの自由度が高い空気調和機の室外機を提供することができる。また実施の形態４では、絶縁部材２０ｃが脚部３４の外面を覆うことにより、脚部３４が露出しない。したがって、腐食媒体となる水滴等が脚部３４に付着するのを防止でき、脚部３４の腐食を抑制することができる。 As described above, also in the fourth embodiment, as in the case of the first embodiment, it is possible to provide an outdoor unit of an air conditioner having a high degree of freedom in combining a motor and a support device. Further, in the fourth embodiment, the insulating member 20c covers the outer surface of the leg portion 34, so that the leg portion 34 is not exposed. Therefore, it is possible to prevent water droplets or the like, which is a corrosion medium, from adhering to the leg portion 34, and it is possible to suppress corrosion of the leg portion 34.

A circular insulating opening 28 is formed in the insulating member 20d, and the motor main body 31 is inserted into the insulating opening 28. A protrusion 22d is formed on the outer peripheral portion 27d of the insulating member 20d along the circumferential direction, and the protrusion 22d engages with the opening 13 to fix the insulating member 20d to the opening 13. FIG. 14 shows a case where a protrusion 22d extending outward in the radial direction is formed at the front end portion of the insulating member 20d. In this case, the protrusion 22d engages with the edge of the opening 13.

図１２及び図１３に示されるように、絶縁部材２０ｄの前面には、ほぼ等間隔に４つのねじ穴２３ｄが設けられている。開口部１３に固定された絶縁部材２０ｄの絶縁開口部２８にモータ６が挿入され、４つの固定ねじ４０によってモータ６の各脚部３４が絶縁部材２０ｄに締結されることにより、モータ６がモータ固定部１２に固定される。モータ６は、モータ本体３１の外周面３２が絶縁部材２０ｄの内周面２６ｄと接触することにより、安定して保持される。 As shown in FIGS. 12 and 13, four screw holes 23d are provided on the front surface of the insulating member 20d at substantially equal intervals. The motor 6 is inserted into the insulating opening 28 of the insulating member 20d fixed to the opening 13, and each leg 34 of the motor 6 is fastened to the insulating member 20d by four fixing screws 40, whereby the motor 6 is motorized. It is fixed to the fixing portion 12. The motor 6 is stably held by the outer peripheral surface 32 of the motor main body 31 coming into contact with the inner peripheral surface 26d of the insulating member 20d.

なお、絶縁部材２０ｄの突起はどのような形状であってもよい。図１５は、本発明の実施の形態５に係るモータ固定部に絶縁部材を固定した状態の他の一例を示す部分断面図である。図１５に示される一例では、絶縁部材２０ｅの前端部と後端部とに、半径方向外側へ延出した突起２２ｅがそれぞれ形成されており、２つの突起２２ｅの間に突起２２ｅから相対的に凹んだ溝部２９が形成されている。モータ固定部１２の開口部１３の縁部が２つの突起２２ｅに挟まれるように溝部２９に配置されることで、絶縁部材２０ｅの外周部２７ｅと開口部１３とが係合し、絶縁部材２０ｅがモータ固定部１２に固定される。 The protrusion of the insulating member 20d may have any shape. FIG. 15 is a partial cross-sectional view showing another example of a state in which the insulating member is fixed to the motor fixing portion according to the fifth embodiment of the present invention. In the example shown in FIG. 15, protrusions 22e extending outward in the radial direction are formed at the front end portion and the rear end portion of the insulating member 20e, respectively, and the protrusions 22e are relatively between the two protrusions 22e. A recessed groove 29 is formed. By arranging the edge portion of the opening portion 13 of the motor fixing portion 12 in the groove portion 29 so as to be sandwiched between the two protrusions 22e, the outer peripheral portion 27e of the insulating member 20e and the opening portion 13 are engaged with each other, and the insulating member 20e Is fixed to the motor fixing portion 12.

以上のように、実施の形態５においても、実施の形態１の場合と同様に、モータ６と支持装置９との組み合わせの自由度が高い空気調和機の室外機１００を提供することができる。また実施の形態５では、絶縁部材２０ｄ、２０ｅの外周部２７ｄ、２７ｅに設けられた突起２２ｄ、２２ｅがモータ固定部１２の開口部１３と係合する。これにより、突起２２ｄ、２２ｅを外周部２７ｄ、２７ｅに形成すればよく、モータ固定部１２と係合させるための爪部２２（図３参照）を設ける必要がない。また、絶縁部材２０ｄ、２０ｅに形成された絶縁開口部２８にモータ本体部３１を挿入できるため、モータ本体部３１においてモータ固定部１２と近接する部分が絶縁部材２０ｄによって環状に覆われ、水滴のブリッジによる腐食を広範囲で抑制できる。 As described above, also in the fifth embodiment, as in the case of the first embodiment, it is possible to provide the outdoor unit 100 of the air conditioner having a high degree of freedom in combining the motor 6 and the support device 9. Further, in the fifth embodiment, the protrusions 22d and 22e provided on the outer peripheral portions 27d and 27e of the insulating members 20d and 20e engage with the opening 13 of the motor fixing portion 12. As a result, the protrusions 22d and 22e may be formed on the outer peripheral portions 27d and 27e, and it is not necessary to provide the claw portion 22 (see FIG. 3) for engaging with the motor fixing portion 12. Further, since the motor main body 31 can be inserted into the insulating openings 28 formed in the insulating members 20d and 20e, the portion of the motor main body 31 close to the motor fixing portion 12 is annularly covered by the insulating member 20d to cause water droplets. Corrosion due to the bridge can be suppressed in a wide range.

なお、本発明の実施の形態は上記実施の形態に限定されず、種々の変更を行うことができる。例えば、鉄製の支持装置９と、アルミニウム製の脚部３４とが固定される場合について説明したが、支持装置９と脚部３４とはそれぞれどのような部材で形成されてもよい。支持装置９と脚部３４とが異なる金属で構成される場合でも、絶縁部材２０、２０ａ、２０ｂ、２０ｃ、２０ｄにより腐食が抑制される。 The embodiment of the present invention is not limited to the above embodiment, and various modifications can be made. For example, the case where the iron support device 9 and the aluminum leg portion 34 are fixed has been described, but the support device 9 and the leg portion 34 may be formed of any member. Even when the support device 9 and the leg portion 34 are made of different metals, corrosion is suppressed by the insulating members 20, 20a, 20b, 20c, and 20d.

また絶縁部材２０、２０ａ、２０ｂ、２０ｃ、２０ｄ、２０ｅの材料は、モータ６と支持装置９とを電気的に絶縁するものであればよい。例えば、一般にモータ外郭及び支持装置９等に用いられることの少ない金属等の材料であって、腐食に強い種類の材料又は腐食に対する強固な表面処理が施された材料により絶縁部材２０、２０ａ、２０ｂ、２０ｃ、２０ｄを形成し、強度を向上させることもできる。あるいは、絶縁部材２０、２０ａ、２０ｂ、２０ｃ、２０ｄ，２０ｅを、弾性の低いゴム等の材料で構成してもよい。この場合、絶縁部材２０、２０ａ、２０ｂ、２０ｃ、２０ｄ，２０ｅが防振材としても機能し、送風機４の振動が筐体１に伝播するのを抑制することができる。 The material of the insulating members 20, 20a, 20b, 20c, 20d, and 20e may be any material that electrically insulates the motor 6 and the support device 9. For example, insulating members 20, 20a, 20b are made of a material such as a metal that is rarely used for a motor outer shell and a support device 9, and is made of a material that is resistant to corrosion or a material that has been subjected to a strong surface treatment against corrosion. , 20c, 20d can be formed to improve the strength. Alternatively, the insulating members 20, 20a, 20b, 20c, 20d, 20e may be made of a material such as rubber having low elasticity. In this case, the insulating members 20, 20a, 20b, 20c, 20d, 20e also function as vibration isolators, and the vibration of the blower 4 can be suppressed from propagating to the housing 1.

また、送風室Ｆに送風機４が２台設置される場合について説明したが、送風機４は１台でもよく、あるいは３台以上でもよい。 Further, although the case where two blowers 4 are installed in the blower chamber F has been described, the number of blowers 4 may be one or three or more.
