Description

本発明は、筐体と風向板とを備える空気調和機の室内機に関する。 The present invention relates to an indoor unit of an air conditioner including a housing and a wind direction plate.

従来、空気調和機の室内機は、筐体と風向板とを備えている。筐体の下部には、空気が吹き出される吹出口が形成されている。風向板は、空気が吹き出す方向を変更するものであり、上部において筐体との間に上下方向の隙間が形成された状態で吹出口を覆うように設けられている。これにより、風向板が回転しても、筐体に接触することを抑制している。特許文献１には、上記のように、風向板と筐体との間に隙間が形成され、風向板が他部品と接触することを抑制する空気調和機が開示されている。 Conventionally, an indoor unit of an air conditioner includes a housing and a wind direction plate. An air outlet through which air is blown out is formed in the lower part of the housing. The wind direction plate changes the direction in which the air is blown out, and is provided so as to cover the air outlet with a vertical gap formed between the wind direction plate and the housing at the upper part. As a result, even if the wind direction plate rotates, it is suppressed from coming into contact with the housing. As described above, Patent Document 1 discloses an air conditioner in which a gap is formed between the wind direction plate and the housing to prevent the wind direction plate from coming into contact with other parts.

特開２００３−１９４３６３号公報Japanese Unexamined Patent Publication No. 2003-194363

しかしながら、特許文献１は、風向板と筐体との間に隙間が形成されているため、隙間を通して室内機の内部が見えてしまい、意匠性が損なわれる。 However, in Patent Document 1, since a gap is formed between the wind direction plate and the housing, the inside of the indoor unit can be seen through the gap, and the design is impaired.

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、風向板と筐体との間に隙間が形成されていても、意匠性が損なわれない空気調和機の室内機を提供するものである。 The present invention has been made to solve the above problems, and provides an indoor unit of an air conditioner in which the design is not impaired even if a gap is formed between the wind direction plate and the housing. To do.

本発明に係る空気調和機の室内機は、被取付部に取り付けられ、空気が吹き出される吹出口が下部に形成された筐体と、上部において筐体との間に上下方向の隙間が形成された状態で吹出口を覆うように設けられ、空気が吹き出す方向を変更する風向板と、を備え、筐体は、吹出口の前端に沿った前端縁部と、隙間の前方において前端縁部から下方に突出し、風向板と対向する位置の全域に設けられた突出部と、を有する。 In the indoor unit of the air conditioner according to the present invention, a vertical gap is formed between the housing, which is attached to the mounted portion and has an air outlet formed at the lower part, and the housing at the upper part. The housing is provided with a wind direction plate that is provided so as to cover the air outlet and changes the direction in which the air is blown out, and the housing has a front end edge along the front end of the air outlet and a front end edge in front of the gap. It has a protruding portion that protrudes downward from the air conditioner and is provided over the entire position facing the wind direction plate.

本発明によれば、隙間の前方において突出部が下方に突出しているため、隙間が突出部に覆われる。このため、室内機の内部が見え難い。従って、風向板と筐体との間に隙間が形成されていても、意匠性を確保することができる。 According to the present invention, since the protruding portion protrudes downward in front of the gap, the gap is covered with the protruding portion. Therefore, it is difficult to see the inside of the indoor unit. Therefore, even if a gap is formed between the wind direction plate and the housing, the design can be ensured.

本実施の形態１によれば、隙間４０の前方において突出部３２が下方に突出しているため、隙間４０が突出部３２に覆われる。このため、室内機３を見上げているユーザ等は、室内機３の内部が見え難い。従って、風向板２３と筐体２０との間に隙間４０が形成されていても、意匠性を確保することができる。また、本実施の形態１は、図８に示すように、突出部３２の下端の高さＡは、風向板２３の上端の高さＢより低い。これにより、突出部３２におけるＢ以下の部分（突出部３２の太字で囲まれた部分）と、風向板２３におけるＡ以上の部分（風向板２３の太字で囲まれた部分）とは、水平からみた場合に重なっている。従って、仮にユーザ等が水平方向から室内機３を見ても、室内機３の内部は突出部３２に阻まれて見えない。即ち、本実施の形態１は、意匠性を更に改善することができる。 According to the first embodiment, since the protruding portion 32 projects downward in front of the gap 40, the gap 40 is covered by the protruding portion 32. Therefore, it is difficult for a user or the like looking up at the indoor unit 3 to see the inside of the indoor unit 3. Therefore, even if a gap 40 is formed between the wind direction plate 23 and the housing 20, the design can be ensured. Further, in the first embodiment, as shown in FIG. 8, the height A of the lower end of the protruding portion 32 is lower than the height B of the upper end of the wind direction plate 23. As a result, the portion of the protruding portion 32 below B (the portion surrounded by bold letters of the protruding portion 32) and the portion above A of the wind direction plate 23 (the portion surrounded by bold letters of the wind direction plate 23) are separated from the horizontal. It overlaps when you see it. Therefore, even if the user or the like looks at the indoor unit 3 from the horizontal direction, the inside of the indoor unit 3 is blocked by the protruding portion 32 and cannot be seen. That is, the first embodiment can further improve the design.

図９は、比較例の室内機１０３の拡大断面図である。ここで、本実施の形態１に係る室内機３の作用を分かりやすくするために、比較例に係る室内機１０３と比較して説明する。比較例に係る室内機１０３の筐体１２０は、前端縁部１３１から下方に突出する突出部を有していない。このため、風向板１２３と筐体１２０との間に形成される隙間４０が、そのまま露出している。従って、室内機１０３を見上げているユーザ等からは、隙間４０を通して室内機１０３の内部が見えてしまい、意匠性が損なわれる。また、意匠性を向上させるために、隙間４０を小さくして目立たないようにしようとすると、風向板１２３が回転したときに筐体１２０に接触する虞がある。 FIG. 9 is an enlarged cross-sectional view of the indoor unit 103 of the comparative example. Here, in order to make it easier to understand the operation of the indoor unit 3 according to the first embodiment, the description will be made in comparison with the indoor unit 103 according to the comparative example. The housing 120 of the indoor unit 103 according to the comparative example does not have a protruding portion protruding downward from the front end edge portion 131. Therefore, the gap 40 formed between the wind direction plate 123 and the housing 120 is exposed as it is. Therefore, a user or the like looking up at the indoor unit 103 can see the inside of the indoor unit 103 through the gap 40, and the design is impaired. Further, if the gap 40 is made small to make it inconspicuous in order to improve the design, there is a risk that the wind direction plate 123 will come into contact with the housing 120 when it rotates.

これに対し、本実施の形態１は、隙間４０の前方において突出部３２が下方に突出しているため、隙間４０が突出部３２に覆われる。従って、風向板２３と筐体２０との間に隙間４０が形成されていても、意匠性を確保することができる。ここで、本実施の形態１は、図６に示すように、風向板２３が２つに分割されたものとなっている。それぞれの風向板２３の駆動用モータ２４が設けられている側は、駆動用モータ２４の回転駆動に追従して回転する。一方、風向板２３の駆動用モータ２４が設けられていない室内機３の中央側は、駆動用モータ２４から離れているため、回転範囲に若干のばらつきが生じる。このため、風向板２３の室内機３の中央側が、隙間４０がより生じ易くなっている。しかし、本実施の形態１は、風向板２３の室内機３の中央側が、自重により若干開いて隙間４０が広がっていても、突出部３２が下方に突出しているため、隙間４０を目立たなくすることができる。 On the other hand, in the first embodiment, since the protruding portion 32 projects downward in front of the gap 40, the gap 40 is covered by the protruding portion 32. Therefore, even if a gap 40 is formed between the wind direction plate 23 and the housing 20, the design can be ensured. Here, in the first embodiment, as shown in FIG. 6, the wind direction plate 23 is divided into two parts. The side of each wind direction plate 23 provided with the drive motor 24 rotates following the rotational drive of the drive motor 24. On the other hand, since the central side of the indoor unit 3 in which the drive motor 24 of the wind direction plate 23 is not provided is separated from the drive motor 24, the rotation range slightly varies. Therefore, a gap 40 is more likely to occur on the central side of the indoor unit 3 of the wind direction plate 23. However, in the first embodiment, even if the central side of the indoor unit 3 of the wind direction plate 23 is slightly opened due to its own weight and the gap 40 is widened, the protruding portion 32 protrudes downward, so that the gap 40 is made inconspicuous. be able to.

また、突出部３２の前面は、前端縁部３１の前面から同一面上に沿って延びている。このように、突出部３２と前端縁部３１との間に段差がないため、意匠性を更に向上させることができる。更に、突出部３２の前面が前端縁部３１の前面から同一面上に沿って延びているため、前端縁部３１と突出部３２とを一体的に成形することができるため、筐体２０を製造する上での製造性を向上させることもできる。 Further, the front surface of the protruding portion 32 extends along the same surface from the front surface of the front end edge portion 31. As described above, since there is no step between the protruding portion 32 and the front end edge portion 31, the design can be further improved. Further, since the front surface of the projecting portion 32 extends along the same surface from the front surface of the front end edge portion 31, the front end edge portion 31 and the projecting portion 32 can be integrally molded, so that the housing 20 can be formed. It is also possible to improve the manufacturability in manufacturing.

実施の形態２．
図１０は、本発明の実施の形態２に係る突出部２３２の拡大断面図である。本実施の形態２は、突出部２３２の下端の高さＡが、風向板２３の上端の高さＢと同じである場合（Ａ＝Ｂ）について例示する。本実施の形態２では、実施の形態１と同一の部分は同一の符号を付して説明を省略し、実施の形態１との相違点を中心に説明する。Embodiment 2.
FIG. 10 is an enlarged cross-sectional view of the protrusion 232 according to the second embodiment of the present invention. The second embodiment exemplifies the case where the height A of the lower end of the protrusion 232 is the same as the height B of the upper end of the wind direction plate 23 (A = B). In the second embodiment, the same parts as those in the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and the differences from the first embodiment will be mainly described.

図１０に示すように、風向板２３と筐体２０との間の隙間４０は、室内機２０３を水平からみた場合に突出部２３２に覆われている。このため、仮にユーザ等が水平方向から室内機２０３を見ても、室内機２０３の内部は突出部２３２に阻まれて見えない。即ち、本実施の形態２は、実施の形態１と同様に、意匠性を更に改善することができる。筐体２０及び風向板２３の製造上のばらつき及び風向板２３の自重等により、突出部２３２の下端の高さＡが、風向板２３の上端の高さＢと同じとなる状態が維持されることは容易ではない。しかし、実施の形態１とあわせ、突出部２３２の下端の高さＡは、風向板２３の上端の高さＢ以下（Ａ≦Ｂ）であれば、意匠性を更に改善することができる。 As shown in FIG. 10, the gap 40 between the wind direction plate 23 and the housing 20 is covered by the protrusion 232 when the indoor unit 203 is viewed from the horizontal. Therefore, even if the user or the like looks at the indoor unit 203 from the horizontal direction, the inside of the indoor unit 203 cannot be seen because it is blocked by the protruding portion 232. That is, the second embodiment can further improve the design as in the first embodiment. Due to manufacturing variations of the housing 20 and the wind direction plate 23, the weight of the wind direction plate 23, and the like, the height A of the lower end of the protrusion 232 is maintained to be the same as the height B of the upper end of the wind direction plate 23. It's not easy. However, in addition to the first embodiment, if the height A of the lower end of the protruding portion 232 is equal to or less than the height B of the upper end of the wind direction plate 23 (A ≦ B), the designability can be further improved.

実施の形態３．
図１１は、本発明の実施の形態３に係る突出部３３２の拡大断面図である。本実施の形態３は、突出部３３２の下端の高さＡが、風向板２３の上端の高さＢよりも高い場合（Ａ＞Ｂ）について例示する。本実施の形態３では、実施の形態１、２と同一の部分は同一の符号を付して説明を省略し、実施の形態１、２との相違点を中心に説明する。Embodiment 3.
FIG. 11 is an enlarged cross-sectional view of the protruding portion 332 according to the third embodiment of the present invention. The third embodiment exemplifies the case where the height A of the lower end of the protrusion 332 is higher than the height B of the upper end of the wind direction plate 23 (A> B). In the third embodiment, the same parts as those of the first and second embodiments are designated by the same reference numerals and the description thereof will be omitted, and the differences from the first and second embodiments will be mainly described.

図１１に示すように、風向板２３と筐体２０との間の隙間４０は、室内機３０３を水平からみた場合に突出部３３２に一部覆われている。このように、突出部３３２が隙間４０の前方において前端縁部３１から下方に突出しており、隙間４０の一部が突出部３３２に覆われているため、隙間４０が目立たない。従って、ユーザ等が室内機３０３を見上げても、室内機３０３の内部は突出部３３２に阻まれて見え難い。 As shown in FIG. 11, the gap 40 between the wind direction plate 23 and the housing 20 is partially covered by the protrusion 332 when the indoor unit 303 is viewed from the horizontal. As described above, the protruding portion 332 projects downward from the front end edge portion 31 in front of the gap 40, and a part of the gap 40 is covered by the protruding portion 332, so that the gap 40 is inconspicuous. Therefore, even if the user or the like looks up at the indoor unit 303, the inside of the indoor unit 303 is obstructed by the protruding portion 332 and is difficult to see.

図６に示すように、本実施の形態３は、風向板２３が２つに分割されたものであると、それぞれの風向板２３の駆動用モータ２４が設けられている側は、駆動用モータ２４の回転駆動に追従して回転する。一方、風向板２３の駆動用モータ２４が設けられていない室内機３の中央側は、駆動用モータ２４から離れているため、回転範囲に若干のばらつきが生じる。このため、風向板２３の室内機３０３の中央側が、隙間４０がより生じ易くなっている。これにより、本実施の形態３のように、突出部３３２の下端の高さＡが、風向板２３の上端の高さＢよりも高く（Ａ＞Ｂ）なっても、突出部３３２が隙間４０の前方において前端縁部３１から下方に突出している。このため、ユーザ等が室内機３０３を見上げても、室内機３０３の内部は突出部３３２に阻まれて見え難い。 As shown in FIG. 6, in the third embodiment, when the wind direction plate 23 is divided into two, the side on which the drive motor 24 of each wind direction plate 23 is provided is the drive motor. It rotates following the rotational drive of 24. On the other hand, since the central side of the indoor unit 3 in which the drive motor 24 of the wind direction plate 23 is not provided is separated from the drive motor 24, the rotation range slightly varies. Therefore, a gap 40 is more likely to occur on the central side of the indoor unit 303 of the wind direction plate 23. As a result, even if the height A of the lower end of the protruding portion 332 is higher than the height B of the upper end of the wind direction plate 23 (A> B) as in the third embodiment, the protruding portion 332 has a gap 40. It protrudes downward from the front end edge 31 in front of the above. Therefore, even if the user or the like looks up at the indoor unit 303, the inside of the indoor unit 303 is obstructed by the protruding portion 332 and is difficult to see.
