Description

本発明は、空気調和機の室外機に係わり、特に、室外機の筺体の側面に固定される電装カバーの構造に関する。   The present invention relates to an outdoor unit of an air conditioner, and more particularly to a structure of an electrical cover fixed to a side surface of a housing of the outdoor unit.

空気調和機の室外機は、筺体の右側面の上下に端子とバルブが配置され、端子とバルブを電装カバーで覆う構造になっている。従来の端子とバルブを電装カバーで覆う構造としては、端子を金属製の端子カバーで覆い、バルブを覆う樹脂製のバルブカバーを端子カバーの上から重ね合せて筺体の右側面に固定する構造になっている（例えば、特許文献１参照）。また、この電装カバーは、室外機を運ぶための取手部となる凹部が端子カバーとバルブカバーの重なる部分に筺体の右側面に向かって形成されている。   The outdoor unit of an air conditioner has a structure in which terminals and valves are arranged above and below the right side surface of the housing, and the terminals and valves are covered with an electrical cover. The conventional structure for covering the terminal and valve with the electrical cover is to cover the terminal with a metal terminal cover, and then overlay the resin valve cover that covers the valve on the terminal cover and fix it to the right side of the housing. (For example, refer to Patent Document 1). In this electrical cover, a recess serving as a handle for carrying the outdoor unit is formed in a portion where the terminal cover and the valve cover overlap toward the right side of the housing.

しかしながら、バルブカバーを端子カバーの上から重ね合せて固定する構造であるため、バルブカバーが大型になり多量の樹脂材料が必要になっていた。また、取手部が端子カバーとバルブカバーが重なる部分に形成されているため、取手部に手指を掛けて室外機を運ぶときに取手部の強度を得ることができる反面、端子カバーとバルブカバーの両方に凹部を形成しなければならず、特に金属製の端子カバーに凹部を形成するのが難しかった。   However, the structure is such that the valve cover is overlaid and fixed from above the terminal cover, so that the valve cover becomes large and a large amount of resin material is required. In addition, since the handle is formed in the part where the terminal cover and valve cover overlap, the strength of the handle can be obtained when carrying the outdoor unit with your fingers on the handle, but the terminal cover and valve cover Both sides had to be formed with recesses, and it was particularly difficult to form recesses in a metal terminal cover.

これらの課題を解決するため、端子カバーに取手部を形成せずに、端子カバーと重ならないようにバルブカバーに取手部を形成することが考えられるが、バブルカバーのみに取手部を形成することになるため、取手部の強度が低下するおそれがあった。また、この場合には、端子カバーとバルブカバーを別々に固定することになるため、端子カバーとバルブカバーの取付作業性が悪くなるおそれがあった。   In order to solve these problems, it is conceivable to form the handle part on the valve cover so as not to overlap the terminal cover without forming the handle part on the terminal cover, but to form the handle part only on the bubble cover. Therefore, the strength of the handle portion may be reduced. In this case, since the terminal cover and the valve cover are separately fixed, the workability of attaching the terminal cover and the valve cover may be deteriorated.

特開平７−６３３７６号公報JP-A-7-63376

本発明は上記問題点に鑑み、樹脂製のバルブカバーの樹脂材料の使用量を抑えつつ、室外機を運ぶための取手部をバルブカバーに容易に形成することができ、かつ、バルブカバーに形成した取手部の強度が低下することがないようにした空気調和機の室外機を提供することを目的とする。   In view of the above problems, the present invention can easily form a handle for carrying an outdoor unit on the valve cover while suppressing the amount of resin material used for the resin valve cover, and can be formed on the valve cover. An object of the present invention is to provide an outdoor unit for an air conditioner that does not reduce the strength of the handle.

上記課題を解決するため、本発明の空気調和機の室外機は、筺体と、筺体の側面に設けられた端子と、端子の下方に設けられたバルブとを備える。この室外機は、端子を覆うように筺体の側面に取付けられる金属製の端子カバーと、端子カバーの下部を覆うように重ね合わせる重合部とバルブを覆う膨出部とを有し端子カバーとともに筺体の側面に固定される樹脂製のバルブカバーとを備える。バルブカバーの膨出部には、重合部の下方近傍の位置に筺体の側面に向かって凹ませた取手部が形成されている。   In order to solve the above problems, an outdoor unit for an air conditioner according to the present invention includes a housing, a terminal provided on a side surface of the housing, and a valve provided below the terminal. This outdoor unit has a metal terminal cover that is attached to the side surface of the housing so as to cover the terminal, a superposition portion that overlaps the lower portion of the terminal cover, and a bulging portion that covers the valve, and the housing together with the terminal cover. And a resin-made valve cover fixed to the side surface. The bulge portion of the valve cover is formed with a handle portion that is recessed toward the side surface of the housing at a position near the lower portion of the overlapping portion.

本発明の空気調和機の室外機によれば、樹脂製のバルブカバーの重合部を金属製の端子カバーの下部を覆うように重ね合わせるため、バルブカバーで端子カバー全体を覆わなくて済むので、バルブカバーの樹脂材料の使用量を抑えることができる。
また、樹脂製のバルブカバーの膨出部には、バルブカバーの重合部の下方近傍の位置に取手部が形成されているので、室外機を運ぶための取手部を金属製の端子カバーに形成しなくて済み、取手部をバルブカバーに容易に形成することができ、その取手部の強度を確保することができる。
さらに、樹脂製のバルブカバーの膨出部に取手部が形成されているため、金属製の端子カバーと樹脂製のバルブカバーの重なる部分に取手部を形成する場合と比べて取手部の奥行が深くなり、取手部に手指を掛け易くすることができる。 According to the outdoor unit of the air conditioner of the present invention, since the overlapping portion of the resin valve cover is overlapped so as to cover the lower part of the metal terminal cover, it is not necessary to cover the entire terminal cover with the valve cover. The amount of resin material used for the valve cover can be reduced.
In addition, the bulge part of the resin valve cover is formed with a handle part near the lower part of the overlapping part of the valve cover, so a handle part for carrying the outdoor unit is formed on the metal terminal cover. The handle portion can be easily formed on the valve cover, and the strength of the handle portion can be ensured.
Furthermore, since the handle is formed at the bulging part of the resin valve cover, the depth of the handle is less than when the handle is formed on the overlapping part of the metal terminal cover and the resin valve cover. It becomes deeper and can make it easier to put fingers on the handle.

As shown in FIGS. 1 and 2, the outdoor unit 1 includes a box-shaped housing 10 that houses therein a heat exchanger, a blower fan, a compressor, an electrical component, a refrigerant pipe, and the like (not shown). The housing 10 includes a bottom plate (not shown), a top plate 11, a front plate 12, and a side plate 13. The front plate 12 of the housing 10 is provided with a fan guard 20, and the side plate 13 of the housing 10 is provided with a terminal 30 and a valve 40 below the terminal 30. The outdoor unit 1 has a structure in which air sucked from the back surface of the housing 10 is heat-exchanged with a refrigerant by a heat exchanger and blown out from the fan guard 20 by rotation of the blower fan.

端子３０は、筺体１０の内部に収容した電装部に接続されるとともに、バルブ４０との間の筺体１０の側面板１３の上を通って室内機に延びる配線３１に接続されている。この端子３０は、筺体１０の側面板１３を矩形状に切欠くことで形成された切欠部１３３を内側に傾斜させて形成した端子台１３１に取付けられている。なお、筺体１０の側面板１３の切欠いた部分には切欠孔１３０が形成される。この端子３０は、筺体１０の側面板１３に取付けられる金属製の端子カバー５０により覆われている。   The terminal 30 is connected to an electrical component housed inside the housing 10 and is connected to a wiring 31 that extends to the indoor unit through the side plate 13 of the housing 10 with the valve 40. The terminal 30 is attached to a terminal block 131 formed by inclining a notch 133 formed by notching the side plate 13 of the housing 10 into a rectangular shape. A notch hole 130 is formed in the notched portion of the side plate 13 of the housing 10. The terminal 30 is covered with a metal terminal cover 50 attached to the side plate 13 of the housing 10.

バルブ４０は、筺体１０の内部に収容した冷媒配管を介して熱交換器や圧縮機に接続されるとともに、室内機に延びる図示しない冷媒配管に接続されている。このバルブ４０は、筺体１０の側面板１３から外側に突出するように配置されている。このバルブ４０は、端子カバー５０とともに筺体１０の側面板１３に固定される樹脂製のバルブカバー６０により覆われている。   The valve 40 is connected to a heat exchanger and a compressor via a refrigerant pipe accommodated in the housing 10 and is connected to a refrigerant pipe (not shown) extending to the indoor unit. The valve 40 is disposed so as to protrude outward from the side plate 13 of the housing 10. The valve 40 is covered with a resin valve cover 60 fixed to the side plate 13 of the housing 10 together with the terminal cover 50.

端子カバー５０は、外側に膨出した形状になっており、端子３０に接続された配線３１が通るように下縁が開放するように形成されている。この端子カバー５０の下部５１は、バルブカバー６０に重なる部分であり、その下部５１の左隅には、図示しないネジでバルブカバー６０とともに共締めするための共締用孔５１０が形成されている。端子カバー５０の上端には、筺体１０の側面板１３の切欠孔１３０の上縁１３０ａに引掛けるための係止片５２が設けられている。また、端子カバー５０の両側端には、筺体１０の側面板１３の切欠孔１３０の左右の側縁１３０ｂに引掛けるための係止片５３が設けられている。   The terminal cover 50 has a shape that bulges outward, and is formed so that the lower edge is opened so that the wiring 31 connected to the terminal 30 passes. A lower portion 51 of the terminal cover 50 is a portion overlapping the valve cover 60, and a fastening hole 510 for fastening together with the valve cover 60 with a screw (not shown) is formed at the left corner of the lower portion 51. At the upper end of the terminal cover 50, a locking piece 52 for hooking on the upper edge 130a of the cutout hole 130 of the side plate 13 of the housing 10 is provided. Further, on both side ends of the terminal cover 50, locking pieces 53 for hooking on the left and right side edges 130 b of the cutout holes 130 of the side plate 13 of the housing 10 are provided.

バルブカバー６０は、外側に膨出した形状になっており、配線３１がバルブ４０の上方に通るように上縁が開放するように形成されている。このバルブカバー６０は、上部に端子カバー５０の下部５１を覆うように重ね合わせる重合部６１と、重合部６１の下部に徐々に外側に傾斜する傾斜面６２１を有し傾斜面６２１と連続的に形成されてバルブ４０を覆う膨出部６２とを備えている。   The valve cover 60 has a shape that bulges outward, and is formed so that the upper edge is opened so that the wiring 31 passes above the valve 40. The valve cover 60 has an overlapping portion 61 that overlaps the upper portion so as to cover the lower portion 51 of the terminal cover 50, and an inclined surface 621 that gradually inclines outward at the lower portion of the overlapping portion 61 and is continuous with the inclined surface 621. And a bulging portion 62 that is formed and covers the valve 40.

バルブカバー６０の重合部６１の左隅には、図示しないネジで端子カバー５０とともに共締めするため、端子カバー５０の共締用孔５１０に位置合わせされる円筒状の共締用孔６１０が形成されている。バルブカバー６０の膨出部６２には、重合部６１の下方近傍の位置に筺体１０の側面板１３に向かって凹ませた取手部６２０が形成されている。この取手部６２０は、バルブカバー６０が筺体１０の側面板１３に固定されたときにバルブ４０の上方の位置になるように形成されている。バルブカバー６０の周縁には、側面板１３の配線３１とバルブ４０の周囲に形成された複数の係止孔１３２に引掛けるための複数の係止片６３が設けられている。   A cylindrical co-tightening hole 610 that is aligned with the co-tightening hole 510 of the terminal cover 50 is formed in the left corner of the overlapping portion 61 of the valve cover 60 to be fastened together with the terminal cover 50 with a screw (not shown). ing. The bulging portion 62 of the valve cover 60 is formed with a handle portion 620 that is recessed toward the side plate 13 of the housing 10 at a position near the lower portion of the overlapping portion 61. The handle 620 is formed so as to be positioned above the valve 40 when the valve cover 60 is fixed to the side plate 13 of the housing 10. On the periphery of the valve cover 60, a plurality of locking pieces 63 for hooking on the wiring 31 of the side plate 13 and the plurality of locking holes 132 formed around the valve 40 are provided.

次に、筺体１０の側面板１３に端子カバー５０とバルブカバー６０を固定する方法について説明する。図１、図２（ｂ）および図２（ｃ）に示すように、筺体１０の側面板１３の切欠孔１３０の上縁１３０ａならびに左右の側縁１３０ｂに、端子カバー５０の上端に設けられた係止片５２および両側端に設けられた係止片５３を引掛ける。これにより、端子３０と配線３１の上部３１０（端子３０側）が端子カバー５０で覆われる。   Next, a method for fixing the terminal cover 50 and the valve cover 60 to the side plate 13 of the housing 10 will be described. As shown in FIGS. 1, 2 (b) and 2 (c), the upper edge 130 a of the cutout hole 130 and the left and right side edges 130 b of the side plate 13 of the housing 10 are provided at the upper end of the terminal cover 50. The locking pieces 52 and the locking pieces 53 provided on both side ends are hooked. Thereby, the terminal 30 and the upper part 310 (terminal 30 side) of the wiring 31 are covered with the terminal cover 50.

その後、筺体１０の側面板１３の複数の係止孔１３２に、バルブカバー６０の周縁に設けられた複数の係止片６３を引掛ける。すると、バルブカバー６０の重合部６１が端子カバー５０の下部５１を覆うように重ね合わされるとともに、端子カバー５０の下部５１に形成された共締用孔５１０に、バルブカバー６０の重合部６１に形成された共締用孔６１０が位置合わせされる。これにより、配線３１の下部３１１（図示しない室内機側）とバルブ４０がバルブカバー６０で覆われる。   Thereafter, the plurality of locking pieces 63 provided on the peripheral edge of the valve cover 60 are hooked on the plurality of locking holes 132 of the side plate 13 of the housing 10. Then, the overlapping portion 61 of the valve cover 60 is overlapped so as to cover the lower portion 51 of the terminal cover 50 and the overlapping portion 510 formed in the lower portion 51 of the terminal cover 50 is connected to the overlapping portion 61 of the valve cover 60. The formed co-tightening hole 610 is aligned. As a result, the lower portion 311 (on the indoor unit side not shown) of the wiring 31 and the valve 40 are covered with the valve cover 60.

次に、端子カバー５０の下部５１に形成された共締用孔５１０およびバルブカバー６０の重合部６１に形成された共締用孔６１０に図示しないネジを通しネジ止めすることで、バルブカバー６０と端子カバー５０が側面板１３に共締めされる。これにより、図２（ａ）に示すように、バルブカバー６０と端子カバー５０が筺体１０の側面板１３に固定される。   Next, a screw (not shown) is passed through and screwed into a co-tightening hole 510 formed in the lower portion 51 of the terminal cover 50 and a co-tightening hole 610 formed in the overlapping portion 61 of the valve cover 60, thereby fixing the valve cover 60. The terminal cover 50 is fastened together with the side plate 13. Thereby, as shown in FIG. 2A, the valve cover 60 and the terminal cover 50 are fixed to the side plate 13 of the housing 10.

以上説明してきた実施形態による空気調和機の室外機１によれば、樹脂製のバルブカバー６０の重合部６１を金属製の端子カバー５０の下部５１を覆うように重ね合わせるため、バルブカバー６０で端子カバー５０の全体を覆わなくて済むので、バルブカバー６０の樹脂材料の使用量を抑えることができる。また、バルブカバー６０の膨出部６２に取手部６２０が形成されているため、バルブカバー６０のみに取手部６２０を形成すればよく、取手部６２０を端子カバー５０に形成しなくて済むので、取手部６２０をバルブカバー６０に容易に形成することができる。さらに、バルブカバー６０の重合部６１の下方近傍の位置に取手部６２０が形成されているため、室外機１を運ぶときに荷重が加わる取手部６２０の強度を確保することができる。   According to the outdoor unit 1 of the air conditioner according to the embodiment described above, the overlapping portion 61 of the resin valve cover 60 is overlapped so as to cover the lower portion 51 of the metal terminal cover 50. Since it is not necessary to cover the entire terminal cover 50, the amount of resin material used for the valve cover 60 can be reduced. Further, since the handle portion 620 is formed on the bulging portion 62 of the valve cover 60, the handle portion 620 may be formed only on the valve cover 60, and the handle portion 620 need not be formed on the terminal cover 50. The handle portion 620 can be easily formed on the valve cover 60. Furthermore, since the handle portion 620 is formed at a position near the lower portion of the overlapping portion 61 of the valve cover 60, the strength of the handle portion 620 to which a load is applied when the outdoor unit 1 is carried can be ensured.

さらに、バルブカバー６０の膨出部６２は重合部６１の下部に徐々に外側に傾斜する傾斜面６２１を有し傾斜面６２１と連続的に形成され、取手部６２０は傾斜面６２１に形成されているとともにバルブ４０の上方の位置に形成されているため、配線３１やバルブ４０に対して邪魔にならずに、背景技術のような端子カバーとバルブカバーの重なる部分に取手部を形成する場合と比べて取手部６２０の奥行が深くなり、取手部６２０に手指を掛け易くすることができる。   Further, the bulging portion 62 of the valve cover 60 has an inclined surface 621 that gradually inclines outward at the lower portion of the overlapping portion 61 and is formed continuously with the inclined surface 621, and the handle portion 620 is formed on the inclined surface 621. And the handle 40 is formed at a position above the valve 40, so that the handle portion is formed in the overlapping portion of the terminal cover and the valve cover as in the background art without disturbing the wiring 31 and the valve 40 Compared to the depth of the handle portion 620, the handle portion 620 can be easily put on the finger.

なお、バルブカバー６０と端子カバー５０が筺体１０の側面板１３に共締めされることで、バルブカバー６０と端子カバー５０が筺体１０の側面板１３に固定されるため、端子カバー５０とバルブカバー６０の取付作業性を良くすることができる。   Since the valve cover 60 and the terminal cover 50 are fastened together with the side plate 13 of the housing 10, the valve cover 60 and the terminal cover 50 are fixed to the side plate 13 of the housing 10. The mounting workability of 60 can be improved.
