　次に、本実施の形態の空気調和機の室内機１００の特徴について説明する。室内機１００は、メンテナンス等の際に、係合構造部７の係合状態を解除し、前面パネル４を回動させて前面ケーシング３の前面側が開かれる。ここで、前面パネル４と前面ケーシング３との境界部分には、係合構造部７の係合状態を解除する際に、使用者が指を掛ける凹形状の指掛け部５０が形成されている。指掛け部５０は、係合構造部７の係合状態を解除して前面パネル４を回動させるために必要であるが、形状によっては非常に目立つため、室内機１００の外観の意匠性を損ねる問題がある。特に、前面ケーシング３が傾斜面部５を有し、該傾斜面部５に指掛け部５０を形成した室内機１００では、前面側から見ると、指掛け部５０の存在が非常に目立つため、外観の意匠性が非常に損なわれる問題があった。 Next, features of the indoor unit 100 of the air conditioner according to the present embodiment will be described. The indoor unit 100 releases the engagement state of the engagement structure portion 7 during maintenance or the like, and rotates the front panel 4 to open the front side of the front casing 3. Here, at the boundary portion between the front panel 4 and the front casing 3, a concave finger-hanging portion 50 is formed on which a user puts his / her finger when releasing the engagement state of the engagement structure portion 7. The finger hooking portion 50 is necessary for releasing the engaged state of the engaging structure portion 7 and rotating the front panel 4. However, depending on the shape, the finger hanging portion 50 is very conspicuous and impairs the design of the appearance of the indoor unit 100. There's a problem. In particular, in the indoor unit 100 in which the front casing 3 has the inclined surface portion 5 and the finger hanging portion 50 is formed on the inclined surface portion 5, since the presence of the finger hanging portion 50 is very conspicuous when viewed from the front surface side, There was a problem that was very damaged.
　そこで、図７及び図８に示すように、本実施の形態における傾斜面部５には、閉じた状態の前面パネル４を開く方向に回動させる際に、使用者が指を掛ける凹状の指掛け部５０が、前面側から背面側に向かって漸次狭まる台形状として設けられている。つまり、本実施の形態の空気調和機の室内機１００では、台形状の広幅部分で指掛け部５０としての機能を確保できると共に、前面側から見た場合に、台形状の狭幅部分でできるだけ存在を目立たなくすることができ、意匠性に優れた外観を呈することができる。 Therefore, as shown in FIGS. 7 and 8, the inclined surface portion 5 in the present embodiment has a concave finger-hanging portion on which the user puts his / her finger when the front panel 4 in the closed state is rotated in the opening direction. 50 is provided as a trapezoidal shape that gradually narrows from the front side toward the back side. That is, in the indoor unit 100 of the air conditioner according to the present embodiment, the trapezoidal wide portion can ensure the function as the finger hanging portion 50 and, when viewed from the front side, the trapezoidal narrow portion exists as much as possible. Can be made inconspicuous, and an appearance excellent in design can be exhibited.
　図６に示すように、指掛け部５０は、使用者の指を指先から第一関節の半分程度の位置まで入れることができる深さであることが望ましい。指先から第一関節の半分程度の位置まで指を入れることができれば、前面パネル４の縁部に指をしっかりと掛けることができ、係合構造部７の係合状態を解除する作業がらくになるからである。 As shown in FIG. 6, it is desirable that the finger-hanging portion 50 has a depth that allows the user's finger to be inserted from the fingertip to a position about half of the first joint. If the finger can be inserted from the fingertip to about half the position of the first joint, the finger can be firmly hooked on the edge of the front panel 4, and the work of releasing the engagement state of the engagement structure portion 7 becomes difficult. Because.
　また、図８に示すように、指掛け部５０は、係合構造部７に隣接する位置に設けられている。つまり、指掛け部５０に入れた使用者の指の力が、係合構造部７に直接伝わるので、係合構造部７の係合状態を容易に解除することができる。但し、指掛け部５０は、係合構造部７の係合状態を解除することができれば、係合構造部７から離れた位置に設けてもよい。 Further, as shown in FIG. 8, the finger hooking portion 50 is provided at a position adjacent to the engaging structure portion 7. That is, the force of the user's finger placed in the finger-hanging portion 50 is directly transmitted to the engagement structure portion 7, so that the engagement state of the engagement structure portion 7 can be easily released. However, the finger hooking portion 50 may be provided at a position away from the engaging structure portion 7 as long as the engagement state of the engaging structure portion 7 can be released.
　また、図６～図８に示すように、指掛け部５０は、係合構造部７によってケーシング１の内面側が塞がれている。具体的には、指掛け部５０は、係合構造部７の係止溝部７１の外面よって内面側が塞がれている。したがって、室内機１００は、指掛け部５０を通じて風又は埃がケーシング１の内部に進入する事態を防ぐことができるので、故障の原因を未然に防ぐことができる。 Further, as shown in FIGS. 6 to 8, the finger hook portion 50 is closed on the inner surface side of the casing 1 by the engaging structure portion 7. Specifically, the inner surface side of the finger-hanging portion 50 is closed by the outer surface of the locking groove portion 71 of the engagement structure portion 7. Therefore, since the indoor unit 100 can prevent a situation in which wind or dust enters the inside of the casing 1 through the finger rest portion 50, the cause of the failure can be prevented in advance.
　以上に、本発明を実施の形態に基づいて説明したが、本発明は上述した実施の形態の構成に限定されるものではない。例えば、図示した室内機１００の内部構成は、一例であって、上述した内容に限定されるものではなく、他の構成要素を含んでもよい。また、室内機１００は、係合構造部７を有さない構成としてもよい。要するに、本発明は、その技術的思想を逸脱しない範囲において、当業者が通常に行う設計変更及び応用のバリエーションの範囲を含むものである。 As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to the structure of embodiment mentioned above. For example, the illustrated internal configuration of the indoor unit 100 is an example, and is not limited to the above-described content, and may include other components. Further, the indoor unit 100 may be configured not to include the engagement structure portion 7. In short, the present invention includes a range of design changes and application variations usually made by those skilled in the art without departing from the technical idea thereof.
