空気調和装置の室内機Indoor unit of air conditioner
　本発明は、ベースプレートに対してフロントパネルが固定された構造を有する空気調和装置の室内機に関するものである。 The present invention relates to an indoor unit of an air conditioner having a structure in which a front panel is fixed to a base plate.
　空気調和装置の室内機のケースは、据え付け作業やメンテナンス作業のために着脱可能となっている。例えば特許文献１には、本体ケースの前面パネルを着脱する構成が開示されている。 The case of the indoor unit of the air conditioner is detachable for installation work and maintenance work. For example, Patent Document 1 discloses a configuration in which a front panel of a main body case is attached and detached.

　しかし、特許文献１の上記構成とは異なり、室内の壁面に固定されたベースプレートとフロントパネルとを固定する場合、ベースプレートとフロントパネルの上部に設けられた固定部が用いられる。固定部としては、ベースプレートに設けられ、下方に凹むと共に挿入穴が形成された凹部と、フロントパネルに設けられ、挿入穴に差し込まれて凹部内に進出して係合する爪部とが用いられる。
　固定部がベースプレート及びフロントパネルの上部に存在するので、視認性が悪く、作業者は手探りでの作業となる。このため、固定部の爪部が凹部に挿入された固定状態なのか、爪部が凹部に挿入されていない解除状態なのかが分からず爪部を誤って外してしまい、予期せぬタイミングでフロントパネルを落下させてしまうおそれがある。 However, unlike the above-mentioned composition of patent documents 1, when fixing a baseplate fixed to a wall surface in a room, and a front panel, a fixing part provided in the upper part of a baseplate and a front panel is used. As the fixing portion, there are used a recess provided on the base plate and recessed downward and having an insertion hole formed therein, and a claw provided on the front panel and inserted into the insertion hole and advanced into and engaged with the recess .
Since the fixing portion is present on the base plate and the upper portion of the front panel, the visibility is poor, and the worker is a groping operation. For this reason, it can not be determined whether the claw portion of the fixing portion is in the fixed state inserted in the concave portion or in the release state in which the claw portion is not inserted in the concave portion, and the claw portion is accidentally removed. There is a risk of dropping the panel.
　また、室内機の機種に応じて、複数の固定部のうち、凹部に爪部を挿入して固定する箇所と、凹部に爪部を挿入せずに固定部として用いずダミーとする箇所とを設ける場合がある。例えば、フロントパネルが重い機種の場合には、フロントパネルが軽い機種に比べて凹部に爪部を挿入して固定する箇所を多くするといった運用が行われる（すなわち、軽い機種はダミーとして用いる固定部が多い）。この様な場合、固定部の凹部に爪部が挿入されているのか否かを作業者の触手によって確実に認識することが求められる。 Further, depending on the model of the indoor unit, among the plurality of fixing parts, a place where the claw part is inserted and fixed in the recess and a place where the nail is not used as a fixing part without inserting the claw part in the recess It may be provided. For example, in the case where the front panel is heavy, operation is performed such that the claws are inserted into the recess and fixed more places than in the case where the front panel is light (that is, the light unit is used as a dummy A lot). In such a case, it is required for the worker's tentacle to reliably recognize whether or not the claw portion is inserted into the recess of the fixed portion.
　本発明は、このような事情に鑑みてなされたものであって、ベースプレートとフロントパネルとを着脱する固定部がベースプレートとフロントパネルの上部に設けられている場合であっても、確実に爪部の存在を認識することができる空気調和装置の室内機を提供することを目的とする。 The present invention has been made in view of such circumstances, and the claw portion can be reliably provided even when the fixing portion for attaching and detaching the base plate and the front panel is provided on the base plate and the upper portion of the front panel. It is an object of the present invention to provide an air conditioner indoor unit capable of recognizing the presence of

Note that FIG. 4 shows a recess 8 in which the claws 9 are not present, and FIG. 5 shows only the claws 9.
　凹部８は、ベースプレート３の上面から下方に凹んだ底面８ａが形成されている。底面８ａの幅方向における中央は平坦面とされている。凹部８の手前側には、爪部９が挿入可能とされた挿入穴８ｂが設けられている。 The recess 8 is formed with a bottom surface 8 a which is recessed downward from the upper surface of the base plate 3. The center in the width direction of the bottom surface 8a is a flat surface. On the front side of the recess 8 is provided an insertion hole 8b into which the claw portion 9 can be inserted.
　爪部９は、フロントパネル５の上部のベースプレート３側の端面から、ベースプレート３に向かって突出するように設けられている。爪部９は、図３のように平面視すると、幅広な略矩形状とされている。爪部９は、取り付けた場合に、凹部８の底面８ａの平坦面に亘って配置されている。爪部９の下面には図示しない係止部が設けられており、ベースプレート３側の被係止部に係合するようになっている。この係合は、爪部９の上面を押圧することによって外れるようになっている。 The claws 9 are provided to project toward the base plate 3 from an end face of the upper portion of the front panel 5 on the base plate 3 side. The claw portion 9 has a wide, substantially rectangular shape in plan view as shown in FIG. The claws 9 are disposed across the flat surface of the bottom surface 8 a of the recess 8 when attached. A locking portion (not shown) is provided on the lower surface of the claw portion 9 so as to be engaged with the locked portion on the base plate 3 side. This engagement is released by pressing the upper surface of the claws 9.
　爪部９の側方と凹部８の側部との間には、作業者の指が入り触手可能な寸法Ａとされた隙間１０が設けられている。寸法Ａとしては、２ｍｍから５ｍｍとされる。この隙間１０によって、作業者は凹部８の底面８ａと爪部９との段差を触手によって認識できるようになっている。なお、隙間１０は、図３のように爪部９の両側に設けても良いし、爪部９の片側のみに設けても良い。 Between the side of the claw portion 9 and the side portion of the recess 8, a gap 10 having a size A in which the finger of the worker can enter and which can be touched by a hand is provided. The dimension A is 2 mm to 5 mm. The gap 10 allows the operator to recognize the step between the bottom surface 8 a of the recess 8 and the claw portion 9 by a tentacle. The clearances 10 may be provided on both sides of the claw portion 9 as shown in FIG. 3 or may be provided on only one side of the claw portion 9.
　爪部９の上面には、幅方向に並んだ２つの凸部９ａが設けられている。凸部９ａの頂面は平坦面とされている。これら凸部９ａは、作業者の触手によって段差が認識可能な形状とされている。なお、凸部９ａの数は３つ以上であっても良いし、１つのみであっても良い。また、凸部９ａに代えて凹んだ凹所としても良い。 On the upper surface of the claw portion 9, two convex portions 9a aligned in the width direction are provided. The top surface of the convex portion 9a is flat. These convex portions 9a are shaped such that the step can be recognized by the operator's tentacle. The number of convex portions 9a may be three or more, or may be only one. Moreover, it may be replaced with the convex part 9a, and may be a concave.
　図２に示すように、固定部７の凹部８の全てに爪部９が挿入されて固定されているわけではない。図２では、第３固定部７ｃには爪部９が挿入されていない。すなわち、フロントパネル５には、第３固定部７ｃに対応する位置に爪部９を備えていない。その他の固定部７すなわち第１固定部７ａ、第２固定部７ｂ、第４固定部７ｄ及び第５固定部７ｅには、爪部９が挿入されている。したがって、これら固定部７ａ，７ｂ，７ｄ，７ｅに対応する位置には、フロントパネル５に爪部９が設けられている。このような構成としたのは、ベースプレート３を共通化して、フロントパネル５を機種に応じて使い分けるためである。例えば、重い機種の場合には軽い機種に比べて多くの爪部９をフロントパネル５に設ける。したがって、軽い機種の場合には、例えば、第１固定部７ａ、第３固定部７ｃ及び第５固定部７ｅの３箇所に対応する位置のみに爪部９を設ける。 As shown in FIG. 2, the claws 9 are not inserted into and fixed to all the recessed portions 8 of the fixing portion 7. In FIG. 2, the claw portion 9 is not inserted into the third fixing portion 7 c. That is, the front panel 5 is not provided with the claw portion 9 at a position corresponding to the third fixing portion 7c. The claw portion 9 is inserted into the other fixing portions 7, that is, the first fixing portion 7 a, the second fixing portion 7 b, the fourth fixing portion 7 d and the fifth fixing portion 7 e. Therefore, the claws 9 are provided on the front panel 5 at positions corresponding to the fixing portions 7a, 7b, 7d and 7e. Such a configuration is to make the base plate 3 in common and to use the front panel 5 properly in accordance with the model. For example, in the case of a heavy type, many claws 9 are provided on the front panel 5 as compared with the light type. Therefore, in the case of a light type, for example, the claws 9 are provided only at three positions corresponding to the first fixing portion 7a, the third fixing portion 7c, and the fifth fixing portion 7e.
　上述の室内機１によれば、以下の作用効果を奏する。
　固定部７の凹部８に挿入された爪部９との間に、作業者の指で触手可能な底面８ａが設けられているので、作業者が底面８ａと爪部９との段差を触手によって認識し、爪部９の存在を確認することができる。したがって、ベースプレート３とフロントパネル５とを着脱する固定部７がベースプレート３とフロントパネル５の上部に設けられており、作業者が視認困難な場合であっても、確実に爪部９の存在を認識することができる。 According to the above-mentioned indoor unit 1, the following effects are achieved.
Since the bottom surface 8a which can be touched by the finger of the worker is provided between the claw portion 9 inserted into the concave portion 8 of the fixing portion 7, the worker can make a step between the bottom surface 8a and the claw portion 9 by the tentacle. It can be recognized to confirm the presence of the claws 9. Therefore, the fixing portion 7 for attaching and detaching the base plate 3 and the front panel 5 is provided on the base plate 3 and the upper portion of the front panel 5, and the presence of the claw portion 9 is surely achieved even when the operator has difficulty in visual recognition. It can be recognized.
　爪部９の上面に、凸部９ａを設けることとしたので、作業者が凸部９ａの段差を触手によって認識し、爪部９の存在を確認することができる。したがって、ベースプレート３とフロントパネル５とを着脱する固定部７がベースプレート３とフロントパネル５の上部に設けられており、作業者が視認困難な場合であっても、確実に爪部９の存在を認識することができる。 Since the convex portion 9a is provided on the upper surface of the claw portion 9, the operator can recognize the level difference of the convex portion 9a by a tentacle and confirm the presence of the claw portion 9. Therefore, the fixing portion 7 for attaching and detaching the base plate 3 and the front panel 5 is provided on the base plate 3 and the upper portion of the front panel 5, and the presence of the claw portion 9 is surely achieved even when the operator has difficulty in visual recognition. It can be recognized.
　複数の固定部７の少なくとも１つには、爪部９が凹部８に配置され、その他の固定部７には爪部９が凹部８に配置されないようにして、室内機１の機種によって、爪部９と凹部８の組み合わせを変えることとした。具体的には、重い機種の場合には軽い機種に比べて多くの爪部９を凹部８に係合させることとする。このような場合であっても、作業者は、爪部９が存在する固定部７と存在しない固定部７とを判別することができるので、機種が異なっていても作業を誤ることがない。 Depending on the model of the indoor unit 1, the claw 9 is disposed in the recess 8 in at least one of the plurality of fixing portions 7 and the claw 9 is not disposed in the recess 8 in the other fixing portions 7. It was decided to change the combination of the portion 9 and the recess 8. Specifically, in the case of a heavy model, more claws 9 are engaged with the recess 8 than in a lighter model. Even in such a case, since the operator can distinguish between the fixing portion 7 in which the claw portion 9 is present and the fixing portion 7 in which the claw portion 9 is not present, even if the type is different, the work is not mistaken.
　なお、上述した実施形態では、凹部８をベースプレート３に設け、爪部９をフロントパネル５に設ける構成としたが、爪部９をベースプレート３に設け、凹部８をフロントパネル５に設ける構成としても良い。 In the embodiment described above, the recess 8 is provided on the base plate 3 and the claws 9 are provided on the front panel 5, but the claws 9 may be provided on the base plate 3 and the recess 8 may be provided on the front panel 5. good.
