Description

本発明は、空気調和機の室外機に係わり、より詳細には、手掛装置の構造に関する。   The present invention relates to an outdoor unit of an air conditioner, and more particularly to the structure of a handhold device.

従来の手掛装置を備えた空気調和機の室外機として、図5(A)および図5(B)に示すように、ケーシング22内に配置された互いに近接する複数の冷媒用の金属管(キャピラリチューブ)51が相互に接触しないように構成することで、金属音を発生させないようにしたものが知られている。   As an outdoor unit of an air conditioner equipped with a conventional hand device, as shown in FIGS. 5 (A) and 5 (B), a plurality of metal tubes for refrigerant (close to each other) arranged in the casing 22 ( It is known that the capillary tube) 51 is configured not to contact each other so as not to generate metal sound.

空気調和機の室外機100の内部は、仕切板21によって、外気を吸い込む吸込口2aを臨ませるように熱交換器4を設置した熱交換器室と、図示しない圧縮機や、複数の冷媒用の金属管(キャピラリチューブ)51を配設した機械室とに区画されている。   The interior of the outdoor unit 100 of the air conditioner includes a heat exchanger chamber in which the heat exchanger 4 is installed so as to face the suction port 2a for sucking outside air through a partition plate 21, a compressor (not shown), and a plurality of refrigerants And a machine room in which a metal tube (capillary tube) 51 is disposed.

機械室の少なくとも背面側を覆っている板金製のケーシング22には開口2cが設けられており、この開口2cと、手指を掛けるために開口2cに装着される合成樹脂製の手掛具31と、冷媒用の複数の金属管(キャピラリチューブ)51を保持する合成樹脂製の保持具32とで、手掛装置3が構成されている。   An opening 2c is provided in the sheet metal casing 22 covering at least the back side of the machine room, and this opening 2c and a synthetic resin handle 31 attached to the opening 2c for placing fingers. The handle device 3 is composed of a synthetic resin holder 32 that holds a plurality of refrigerant metal pipes (capillary tubes) 51.

手掛具31は、開口2cの周縁部に手掛具31の縁部31bが係合して装着された際、この縁部31bの上部位置に、手指に馴染みやすいように架設部31cが連続形成されていることにより、手指を掛けやすくした構成になっている。   When the edge 31b of the handle 31 is engaged with and attached to the peripheral edge of the opening 2c, the handle 31 is continuously connected to the upper portion of the edge 31b so as to become familiar with fingers. By being formed, it is configured to make it easier to place fingers.

また、手掛装置3を構成する手掛具31は、何らかの外力が作用することで、手掛具31の縁部31bが開口2cから外れることによって機械室内に落下しないように、装着時のガタつき(遊び)をなくして、強固に装着されるように工夫された構成になっている。   In addition, the handle 31 constituting the handle device 3 has a backlash at the time of mounting so that the edge 31b of the handle 31 will not fall into the machine room due to detachment from the opening 2c due to some external force. It has a structure that is devised so that it can be firmly attached without any play.

すなわち、開口2cに装着された手掛具31の後部に、複数の冷媒用の金属管(キャピラリチューブ)51を保持するための保持具32を一体成形することで手掛装置3が構成されており、この保持具32が複数の冷媒用の金属管(キャピラリチューブ)51を保持することによって、手掛具31の縁部31bが開口2cから外れなくなるように工夫されている。   That is, the handle device 3 is configured by integrally forming a holder 32 for holding a plurality of refrigerant metal tubes (capillary tubes) 51 at the rear portion of the handle 31 attached to the opening 2c. The holder 32 holds a plurality of refrigerant metal tubes (capillary tubes) 51 so that the edge 31b of the handle 31 is not detached from the opening 2c.

また、手掛穴部31aは、上方に膨出させることで手指を掛けた時に指先を収容できるように構成されるとともに、手掛具31の縁部31bが、開口2cの周縁部にケーシング22の外面側から係合しているのに対し、上方に膨出させた手掛穴部31aの端面31dは、ケーシング22の内面側に当接させることで手掛具31を確実に装着できるようにしている。   In addition, the handhold hole 31a is configured to swell upward so that the fingertip can be accommodated when the finger is hung, and the edge 31b of the handhold tool 31 is formed in the casing 22 on the peripheral edge of the opening 2c. The end surface 31d of the handle hole portion 31a bulged upward is brought into contact with the inner surface side of the casing 22 so that the handle 31 can be securely mounted. I have to.

これらにより、図示しない圧縮機などの振動を受けた場合であっても、複数の冷媒用の金属管(キャピラリチューブ)51が揺れることで互いに接触してしまうのを防ぐことができるとともに、ガタつき(遊び)のない強固な手掛装置3となることから、例えば、冷媒用の複数の金属管(キャピラリチューブ)51に緩衝材を貼り付けることで、相互の接触により発生する金属音を抑制するといった処置を施す必要がない構成になっていた(例えば、特許文献1)。   As a result, even when subjected to vibration of a compressor (not shown) or the like, the plurality of refrigerant metal tubes (capillary tubes) 51 can be prevented from coming into contact with each other due to shaking and rattling. Since it becomes the strong hand-held device 3 without (play), for example, by attaching a buffer material to a plurality of metal tubes (capillary tubes) 51 for refrigerant, metal sound generated by mutual contact is suppressed. Such a configuration is not required (for example, Patent Document 1).

しかしながら、合成樹脂からなる手掛具31を備えた手掛装置3は、指先が収容される手掛穴部31aを上方に膨出させるとともに、架設部31cを設けることで手指が馴染みやすくなり、また、ガタつき(遊び)が生じない強固な構成にしている反面、PL対応の信頼性を向上させるための室外機全体の不燃化対策が不充分であった。   However, the handhold device 3 provided with the handholding tool 31 made of a synthetic resin bulges the handholding hole 31a in which the fingertip is accommodated upward, and it is easy to become familiar with the fingers by providing the erection part 31c. In addition, while it has a strong configuration that does not cause backlash (play), the countermeasure for incombustibility of the entire outdoor unit to improve the reliability for PL is insufficient.

なお、機械室内に延出するように折曲形成される延出部5と、開口2cの上縁部に折曲形成されるL字部2iと、開口2cの左縁に折曲形成される左縁の爪部2eおよび開口2cの右縁に折曲形成される右縁の爪部2eとは、展開図として図2(B)に示すように構成されており、開口2cを形成する際、同図に破線で示す折曲箇所aで折り曲げることによって、図2(A)に示すように同時に折曲形成されることになる。   It is to be noted that the extension portion 5 that is bent so as to extend into the machine room, the L-shaped portion 2i that is bent at the upper edge portion of the opening 2c, and the left edge of the opening 2c are bent. The left edge claw portion 2e and the right edge claw portion 2e bent at the right edge of the opening 2c are configured as shown in FIG. 2B as a development view, and when the opening 2c is formed. By bending at a bending location a indicated by a broken line in the same figure, bending is simultaneously formed as shown in FIG.

その際、機械室内に延出するように折曲形成される延出部5と、開口2cの上縁部に折曲形成されるL字部2iと、開口2cの左縁に折曲形成される左縁の爪部2eおよび開口2cの右縁に折曲形成される右縁の爪部2eとは、展開図として図2(B)に示すようにプレス加工したのち、図2(A)に示すように折曲形成することにより、形状および寸法の精度を高めることができるようになる。   At that time, the extension portion 5 is bent so as to extend into the machine room, the L-shaped portion 2i is bent at the upper edge portion of the opening 2c, and is bent at the left edge of the opening 2c. The left edge claw portion 2e and the right edge claw portion 2e bent at the right edge of the opening 2c are pressed as shown in FIG. As shown in FIG. 5, the accuracy of the shape and size can be increased by forming a bend.

手掛具カバー6は、図4(A)乃至図4(C)に示すような板金製でなり、手掛具30の凹部3bおよび延出部5を機械室側から覆うカバー部6aと、カバー部6aの周縁に連続形成されることにより、ケーシング2および前面カバー20に設けられた段部2dの裏面に密接するフランジ部6bとを備えた構成になっている。   The hand cover 6 is made of sheet metal as shown in FIGS. 4 (A) to 4 (C), and the cover 6a covers the recess 3b and the extension 5 of the hand 30 from the machine room side, By being continuously formed at the periphery of the cover portion 6a, the casing 2 and the flange portion 6b in close contact with the back surface of the step portion 2d provided on the front cover 20 are provided.

手掛具カバー6のカバー部6aは、手掛具30に備えた凹部3bおよび開口2cの下縁部に折曲形成された延出部5を完全に覆うことができるように形成されており、手掛具カバー6のフランジ部6bは、カバー部6aによって凹部3bおよび延出部5を覆った状態で、図4(B)の爪部拡大図に示す矢印fのようにスライドさせることで、開口2cの左縁に折曲形成された左縁の爪部2eおよび開口2cの右縁に折曲形成された右縁の爪部2eに対し、図4(C)の爪部拡大図に示すように係止される左縁の係止部6cおよび右縁の係止部6cを備えている。   The cover portion 6a of the handle cover 6 is formed so as to be able to completely cover the recessed portion 3b provided in the handle 30 and the extended portion 5 formed at the lower edge of the opening 2c. The flange portion 6b of the hand cover 6 is slid as shown by the arrow f shown in the enlarged view of the claw portion in FIG. 4B with the cover portion 6a covering the recess 3b and the extension portion 5. FIG. 4 (C) is an enlarged view of the claw portion 2e bent at the left edge of the opening 2c and the claw portion 2e of the right edge bent at the right edge of the opening 2c.

なお、板金製の手掛具カバー6は、カバー部6aを形成する際、例えば、板金がプレス加工によって絞り加工されることにより、材料取りの効率化を図って残材が多くならないように形成してもよく、または、図4(A)に示すe部(対向面を含む)において、折曲形成された折曲面の一部がスポット溶接されることで強固に形成する構成にしてもよい。   In addition, when forming the cover portion 6a, the sheet metal handle cover 6 is formed so that, for example, the sheet metal is drawn by press working so as to increase the efficiency of material removal and not increase the remaining material. Alternatively, in a portion e (including the facing surface) shown in FIG. 4A, a part of the bent curved surface that is formed may be firmly formed by spot welding. .

ここで、ケーシング2および前面カバー20に設けられた開口2cに対し、ケーシング2および前面カバー20の外面側から手掛具30を装着して、内面側から、複数の下部係止部2hに複数の下部係止爪3eを正確に係止すると同時に、複数の上部係止部2gに複数の上部係止爪3cを正確に係止できたこと、また、開口2cの周縁部に設けられた段部2dに手掛フランジ部3dを密接させたことを確認したのち、ケーシング2および前面カバー20にその内面側から手掛具カバー6を装着する手順について、図4(A)乃至図4(C)に基づいて、以下に説明する。   Here, a handle 30 is attached to the opening 2c provided in the casing 2 and the front cover 20 from the outer surface side of the casing 2 and the front cover 20, and a plurality of lower locking portions 2h are provided from the inner surface side. At the same time that the lower locking claws 3e are correctly locked, the plurality of upper locking claws 3c can be accurately locked to the plurality of upper locking portions 2g, and the step provided at the peripheral edge of the opening 2c After confirming that the handle flange portion 3d is in close contact with the portion 2d, the procedure for attaching the handle cover 6 to the casing 2 and the front cover 20 from the inner surface side is shown in FIGS. ) Will be described below.

図4(A)に示す手掛具カバー6を手に持ち、この手掛具カバー6のカバー部6aで、開口2cに装着された手掛具30に備えた凹部3bおよび開口2cに折曲形成された延出部5を覆いながら、図4(B)に示すように、手掛具カバー6に備えたフランジ部6bをケーシング2および前面カバー20の裏面に当接しながら、フランジ部6bに備えた複数の係止部6cに、開口2cの左縁に折曲形成された左縁の爪部2eを挿入させ、開口2cの右縁に折曲形成された右縁の爪部2eを挿入させる。   Holding the hand cover 6 shown in FIG. 4 (A) in the hand, the cover 6a of the hand cover 6 is bent into the recess 3b and the opening 2c provided in the hand 30 attached to the opening 2c. As shown in FIG. 4B, the flange portion 6b provided on the hand cover 6 is brought into contact with the back surface of the casing 2 and the front cover 20 while covering the formed extension portion 5, while the flange portion 6b A left edge claw portion 2e bent at the left edge of the opening 2c is inserted into the plurality of engaging portions 6c provided, and a right edge claw portion 2e bent at the right edge of the opening 2c is inserted. Let

次に、図4(B)の爪部拡大図に示す矢印fのように、手掛具カバー6を左縁の爪部2eおよび右縁の爪部2eでガイドしながらスライドさせることにより、図4(C)の爪部拡大図に示すように、手掛具カバー6に備えたフランジ部6bに設けられた複数の係止部6cを、開口2cの左縁に折曲形成された左縁の爪部2eを構成する係止溝2fに係止させ、開口2cの右縁に折曲形成された右縁の爪部2eを構成する係止溝2fに係止させる。   Next, as shown by an arrow f in the enlarged nail view of FIG. 4B, the handle cover 6 is slid while being guided by the left edge claw part 2e and the right edge claw part 2e. 4 (C), a left edge formed by bending a plurality of locking portions 6c provided on a flange portion 6b provided on the handle cover 6 at the left edge of the opening 2c. The claw portion 2e is engaged with a locking groove 2f, and the right edge claw portion 2e is bent at the right edge of the opening 2c.

その際、スライドさせた手掛具カバー6は、通し孔6dが設けられている一面(底面)が、図1(D)に二点鎖線(想像線)で示すように延出部5に当接することになり、これによって、図4(A)乃至図4(C)に示すように、延出部5に設けられた逃げ孔5bを挿通している手掛具30に備えた複数の下部係止爪3eの一部が、手掛具カバー6に設けられた係合部6eに係合する。   At this time, the slidable handle cover 6 has one surface (bottom surface) provided with a through-hole 6d abutting against the extending portion 5 as shown by a two-dot chain line (imaginary line) in FIG. Accordingly, as shown in FIGS. 4 (A) to 4 (C), a plurality of lower portions provided in the handgrip 30 through which the escape holes 5b provided in the extending portion 5 are inserted. A part of the locking claw 3e is engaged with an engaging portion 6e provided on the hand hook cover 6.

なお、手掛具カバー6は、スライド時に左縁の爪部2eおよび右縁の爪部2eによってガイドされ、かつ、左縁の爪部2eおよび右縁の爪部2eによって左右方向にガタ付き(遊び)が生じないように規制されるとともに、複数の下部係止爪3eの一部が複数の係合部6eに係合することになる。   The hand cover 6 is guided by the left edge claw portion 2e and the right edge claw portion 2e during sliding, and is rattled in the left-right direction by the left edge claw portion 2e and the right edge claw portion 2e ( (Play) is controlled so as not to occur, and a part of the plurality of lower locking claws 3e is engaged with the plurality of engaging portions 6e.

これによって、延出部5に設けられたねじ孔5aに対して手掛具カバー6に設けられた通し孔6dが位置合わせされることになり、この通し孔6dを通した図4(C)に示すねじ7をねじ孔5aに螺着し、手掛具カバー6を延出部5にねじ締め固定することで、図1(D)に二点鎖線(想像線)で示すように、手掛具カバー6により、手掛具30に備えた凹部3bおよび開口2cに折曲形成された延出部5を覆うことができるようになる。   As a result, the through hole 6d provided in the handle cover 6 is aligned with the screw hole 5a provided in the extending portion 5, and FIG. 1 is screwed into the screw hole 5a, and the handle cover 6 is screwed and fixed to the extension portion 5, so that as shown by a two-dot chain line (imaginary line) in FIG. The hook cover 6 can cover the recessed portion 3b provided in the hand hook 30 and the extending portion 5 formed by bending in the opening 2c.

これによって、板金製の手掛具カバー6は、仮に、合成樹脂製の手掛具30が火災に遭って高温になり、溶け始めてケーシング2および前面カバー20に設けられた開口2cから機外に落下したとしても、この開口2cは、図1(D)に二点鎖線(想像線)で示すように手掛具カバー6で遮蔽されることになって、PL対応の信頼性を向上させるための室外機1全体の不燃化対策を実現できる。   As a result, the metal plate handle 6 is heated from the synthetic resin handle 30 in the event of a fire, and starts to melt from the opening 2c provided in the casing 2 and the front cover 20 to the outside. Even if it falls, the opening 2c is shielded by the hand cover 6 as shown by a two-dot chain line (imaginary line) in FIG. 1 (D) in order to improve the reliability corresponding to the PL. The non-combustible measures for the entire outdoor unit 1 can be realized.

すなわち、例えば、近くで火災が発生することによって、高温に晒された合成樹脂製の手掛具30が溶け始めた場合であっても、この溶け始めた手掛具30が室外機1の機械室内に落下することなく、先端位置が基端部に対して高くなるように傾斜させた延出部5の上面を滑り落ちて機外に排出されることから、溶け始めて火種となった手掛具30が落下することによって機械室内が延焼してしまうという虞がない。   That is, for example, even when a synthetic resin handle 30 exposed to a high temperature starts to melt due to a fire in the vicinity, the melted handle 30 is the machine of the outdoor unit 1. Since it does not fall into the room and slides down on the upper surface of the extension part 5 inclined so that the tip position is higher than the base end part, it is discharged out of the machine, so it is a clue that started to melt and became a fire type There is no fear that the machine room will spread by dropping the tool 30.

なお、図1(D)および図1(E)は、手掛具30が開口2cに装着された状態を要部断面図として示しているが、図1(D)では、手掛具カバー6を二点鎖線(想像線)で示しており、例えば、高温で溶け始めた手掛具30が延出部5の上面に落下した際、手掛具カバー6が、ケーシング2および前面カバー20に設けられた開口2cの一部のみを覆うのではなく、開口2cの全域を遮蔽するように装着されていることから、手掛具30は正確に機外に排出されることになる。   1 (D) and 1 (E) show a state in which the handle 30 is attached to the opening 2c as a cross-sectional view of the main part, but in FIG. 1 (D), the handle hook 6 Is indicated by a two-dot chain line (imaginary line). For example, when the handle 30 that has started to melt at a high temperature falls on the upper surface of the extension portion 5, the handle cover 6 is attached to the casing 2 and the front cover 20. Since it is mounted not to cover only a part of the provided opening 2c but to cover the entire area of the opening 2c, the handle 30 is accurately discharged out of the machine.

以上説明したように、本発明の構成によれば、手掛装置3が、板金製のケーシング2および前面カバー20に設けられた開口2cと、開口2cに装着された合成樹脂製の手掛具30と、開口2cの下縁部から機械室内に延出した延出部5と、延出部5および凹部3bを覆った板金製の手掛具カバー6とからなる構成にしたので、室外機1を設置する際、手指が馴染みやすい手掛具30に手指を掛けて移動させることができるようになり、また、高温になり溶け始めて落下した場合の手掛具30は機外に排出されるとともに、開口2cは、手掛具カバー6で遮蔽されることになって、室外機1全体の不燃化対策を実現することでPL対応の信頼性を向上させた手掛装置3を有する空気調和機の室外機1となる。   As described above, according to the configuration of the present invention, the handle device 3 includes the opening 2c provided in the sheet metal casing 2 and the front cover 20, and the synthetic resin handle attached to the opening 2c. 30, an extension portion 5 extending from the lower edge portion of the opening 2c into the machine room, and a sheet metal handle cover 6 covering the extension portion 5 and the recess portion 3b. When installing 1, the hand 30 can be moved by placing it on a hand tool 30 that is easy to get used to, and the hand tool 30 when it starts to melt and falls is discharged out of the machine. At the same time, the opening 2c is shielded by the hand cover 6 and the air conditioner has the hand device 3 that improves the reliability for PL by realizing the non-combustibility measures for the entire outdoor unit 1. It becomes the outdoor unit 1 of the machine.
