Description

【０００１】
【発明の属する技術分野】
この発明は、空気調和機の室内熱交換器等を固定するのに使用される熱交換器固定板およびそれを用いた空気調和機に関する。
【０００２】
【従来の技術および発明が解決しようとする課題】
従来、空気調和機の室内ユニットにおいて、室内熱交換器の側面部を底フレームに固定すると共に、吸い込み空気が室内熱交換器を通らずにファン室側に流れ込むのを防止するための熱交換器固定板がある。この熱交換器固定板は、室内熱交換器の側面部から突出する伝熱管のヘアピン部を挿入するための挿入穴がヘアピン部毎に形成されており、組立時にこの挿入穴に伝熱管のヘアピン部を挿入して、室内熱交換器の位置決めを行っている。しかしながら、上記熱交換器固定板では、挿入穴に挿入された熱交換器の伝熱管のヘアピン部に生じた結露水および熱交換器固定板そのものに生じた結露水をドレンパン等に案内する流路が考慮されていないため、伝熱管のヘアピン部に生じる結露水の処理が確実にできず、滞留した結露水がドレンパン以外のところに飛び出すという問題がある。
【０００３】
そこで、この発明の目的は、結露水を確実に処理できる熱交換器固定板およびそれを用いた空気調和機を提供することにある。
【０００４】
【課題を解決するための手段】
上記目的を達成するため、請求項１の熱交換器固定板は、放熱フィンと伝熱管を有する熱交換器の少なくとも一方の側面部をケーシングに固定するための樹脂製の熱交換器固定板であって、上記熱交換器の側面部に裏面側が対向する板状基部と、上記板状基部に形成され、上記熱交換器の上記伝熱管のヘアピン部が挿入される挿入穴と、上記板状基部の表面側かつ上記挿入穴の外周部の少なくとも一部に立設された壁部と、上記壁部の内側かつ裏面側に形成された溝部とを備えたことを特徴としている。
【０００５】
上記請求項１の熱交換器固定板によれば、上記壁部の内側かつ裏面側に形成された溝部によって、壁部の内側に生じた結露水を板状基部の裏面側(熱交換器の側面部と対向する側)に案内して、上記溝部に案内された結露水は、板状基部の裏面側や熱交換器の側面部に沿って下方に流れる。そうして、上記板状基部の裏面側や熱交換器の側面部に沿って流れ落ちる結露水を、熱交換器の結露水を処理するドレンパン等に溜めることによって、結露水を確実に処理できる。
【０００６】

【００１０】
また、請求項２の熱交換器固定板は、放熱フィンと伝熱管を有する熱交換器の少なくとも一方の側面部をケーシングに固定するための樹脂製の熱交換器固定板であって、上記熱交換器の側面部に裏面側が対向する板状基部と、上記板状基部に形成され、上記熱交換器の上記伝熱管のヘアピン部が挿入される挿入穴と、上記板状基部の表面側かつ上記挿入穴の外周部の少なくとも一部に立設された壁部と、上記壁部の内側かつ裏面側に形成された溝部と、上記板状基部の表面側に、上記壁部の外側かつ下側に一端が連なるように立設されたリブとを備えたことを特徴としている。

上記請求項２の熱交換器固定板によれば、上記壁部の内側かつ裏面側に形成された溝部によって、壁部の内側に生じた結露水を板状基部の裏面側(熱交換器の側面部と対向する側)に案内して、溝部に案内された結露水は、板状基部の裏面側または熱交換器の側面部に沿って下方に流れる。また、上記壁部の外側かつ下側に一端が連なるように上記板状基部の表面側に立設されたリブによって、壁部の外側に生じた結露水をリブにより下方に案内して、リブに案内された結露水は、板状基部の表面側を下方に流れる。そうして、上記溝部とリブに案内された結露水を、熱交換器の結露水を処理するドレンパン等に溜めることによって、結露水を確実に処理でき、リブにより板状基部の補強もできる。
【００１２】
また、請求項３の熱交換器固定板は、放熱フィンと伝熱管を有する熱交換器の少なくとも一方の側面部をケーシングに固定するための樹脂製の熱交換器固定板であって、上記熱交換器の側面部に裏面側が対向する板状基部と、上記板状基部に形成され、上記熱交換器の上記伝熱管のヘアピン部が挿入される挿入穴と、上記板状基部の表面側かつ上記挿入穴の外周部の少なくとも一部に立設された壁部と、上記壁部の内側かつ裏面側に形成された溝部と、上記板状基部の表面側に、上記壁部の外側かつ下側に一端が連なるように立設されたリブとを備え、上記板状基部の外縁部の側面が不連続であって、上記板状基部の外縁部の側面に生じた結露水を上記外縁部よりも内側かつ下方に向かって案内する流路が上記板状基部の表面側に形成されていることを特徴としている。
【００１３】
上記請求項３の熱交換器固定板によれば、上記壁部の内側かつ裏面側に形成された溝部によって、壁部の内側に生じた結露水を板状基部の裏面側(熱交換器の側面部と対向する側)に案内して、溝部に案内された結露水は、板状基部の裏面側または熱交換器の側面部に沿って下方に流れる。また、上記壁部の外側かつ下側に一端が連なるように上記板状基部の表面側に立設されたリブによって、壁部の外側に生じた結露水をリブにより下方に案内して、リブに案内された結露水は、板状基部の表面側を下方に流れる。上記板状基部の外縁部の側面が不連続であって、上記板状基部の外縁部の側面に生じた結露水を上記板状基部の表面側に形成された流路によって上記外縁部よりも内側かつ下方に向かって案内して、流路に案内された結露水は、板状基部の表面側を下方に流れる。そうして、上記溝部,リブおよび流路に案内された結露水を、熱交換器の結露水を処理するドレンパン等に溜めることによって、結露水を確実に処理できる。
【００１４】
また、請求項４の熱交換器固定板は、請求項２または３のいずれか１つの熱交換器固定板において、上記リブは、上記壁部の外側かつ下側に接続された一端から他端に向かって徐々に高さを低くしたことを特徴としている。
【００１５】
上記請求項４の熱交換器固定板によれば、上記リブの高さを、上記壁部の外側かつ下側に接続された一端から他端に向かって徐々に低くすることによって、上記壁部の外側先端に生じた結露水を徐々に板状基部の表面に案内するので、確実に結露水の飛散を防止できる。
【００１６】

【００２５】
また、上記板状基部４０の略平行四辺形状の挿入穴４４近傍に、長穴形状の挿入穴４８〜５０の配列方向に対して所定の角度で交差する直線上に沿って第１の外縁部３７を形成し、さらに板状基部４０の略平行四辺形状の挿入穴４５近傍および長穴形状の挿入穴５１近傍に、長穴形状の挿入穴４８〜５０の配列方向に対して所定の角度で交差する直線上に沿って第２の外縁部３８,第３の外縁部３９を形成している。上記熱交換器固定板５の略平行四辺形状の挿入穴４４近傍の図４中右側の第１の外縁部３７に、所定の間隔をあけて円弧形状の切り欠き９３,９４を形成している。上記熱交換器固定板５の略平行四辺形状の挿入穴４５近傍の図４中右側の第２の外縁部３８に、所定の間隔をあけて円弧形状の切り欠き９５,９６を形成している。さらに、上記熱交換器固定板５の長穴形状の挿入穴５１近傍の図４中右側の第３の外縁部３９に、所定の間隔をあけて円弧形状の切り欠き９７,９８を形成している。また、上記板状基部４０の挿入穴４５の図４中左側に、確認窓５３を形成している。

【００２７】
また、上記略平行四辺形状の挿入穴４３と同様に、略平行四辺形状の挿入穴４１,４７(図４に示す)の壁部６１,６７それぞれに、対向する係合爪１０２を２つ形成している。さらに、略平行四辺形状の挿入穴４５(図４に示す)の壁部６５に係合爪１０２を１つ形成している。上記複数の係合爪１０２によって、室内熱交換器２(図２に示す)の伝熱管のヘアピン部１１Ａ,１１Ｃ,１１Ｄ,１１Ｆ,１３Ａ,１４Ｂ,１４Ｅを係合して固定する。

【００２９】
また、図８は上記熱交換器固定板５の裏面図である。上記熱交換器固定板５の裏面側が室内熱交換器２(図２に示す)の左側面と対向する。図８に示すように、略平行四辺形状の挿入穴４１〜４７の壁部６１〜６７(図４に示す)の下側に、一部が欠けた略円形の断面形状の溝部１１１〜１１７を形成し、長穴形状の挿入穴５２の壁部７２(図４に示す)の下側に、一部が欠けた略円形の断面形状の溝部１１８を形成している。上記挿入穴４１〜４７の壁部６１〜６７(図４に示す)および挿入穴５２の壁部７２(図４に示す)の内側壁面に生じた結露水を熱交換器固定板５の裏面側に案内する。そして、上記熱交換器固定板５の裏面側に案内された結露水は、室内熱交換器２に生じた結露水と共に下方のドレンパン(図示せず)に流れ落ちる。
【００３０】
また、図９は上記室内熱交換器２の左側面図を示し、第１前面熱交換器の各熱交換部１１,１２,１３の側面に、放熱フィン(図示せず)の外側を保護するための管板１５,１６,１７を夫々取り付けている。また、上記背面熱交換器１４の側面に、放熱フィン(図示せず)の外側を保護するための管板１８を取り付けている(第２前面熱交換器(２１,２２,２３)の側面にも管板を取り付けているが説明を省略する)。
【００３１】
図１０は上記室内熱交換器２の左側面部に図４〜図８に示す熱交換器固定板５を取り付けた状態を示している。図１０に示すように、上記板状基部４０の外縁部の側面が不連続であって、板状基部４０の外縁部の側面に生じた結露水を上記外縁部よりも内側かつ下方に向かって案内する流路が板状基部４０の表面側に形成されている。また、上記熱交換器固定板５の確認窓５３からは、熱交換部１３の管板１７に設けられた固定用部位である係合部１７a(図９に示す)が目視できるようにしている。
【００３２】
また、図１１は上記熱交換器固定板５により固定された室内熱交換器２が底フレーム１に取り付けられた状態を示す正面図である。
【００３３】
上記熱交換器固定板５では、壁部６１〜６７,７２の内側かつ裏面側に形成された溝部１１１〜１１８によって、壁部６１〜６７,７２の内側に生じた結露水を板状基部４０の裏面側に案内し、その溝部１１１〜１１８により案内された結露水は、板状基部４０の裏面側または室内熱交換器２の側面部に沿って下方に流れてドレンパンに溜まるので、結露水を確実に処理することができる。
【００３４】
また、上記熱交換器固定板５の壁部６１〜６７,７２の外側かつ下側に一端が連なるように板状基部４０の表面側に立設されたリブ８１〜８７,９２によって、壁部６１〜６７,７２の外側に生じた結露水をリブ８１〜８７,９２により下方に案内し、そのリブ８１〜８７,９２に案内された結露水は、板状基部４０の表面側を下方に流れてドレンパンに溜まるので、結露水を確実に処理することができ、リブ８１〜８７,９２により板状基部４０の補強もできる。
【００３５】
また、上記熱交換器固定板５の板状基部４０の外縁部の側面が不連続であるから、その外縁部の側面に生じた結露水がそのまま外縁部に沿って流れ落ちることがなく、板状基部４０の外縁部の側面に生じた結露水を図１０に示すように板状基部４０の表面側に形成された流路(図１０に示す点線の矢印)によって外縁部よりも内側かつ下方に向かって案内し、その流路に案内された結露水をドレンパンに溜めるので、結露水を確実に処理することができる。
【００３６】
また、上記リブ１１１〜１１８の高さを、壁部６１〜６７,７２の外側かつ下側に接続された一端から他端に向かって徐々に低くすることによって、壁部６１〜６７,７２の外側先端に生じた結露水も徐々に板状基部４０の表面に案内するので、結露水の飛散をより確実に防止することができる。
【００３７】
また、上記結露水を確実に処理する熱交換器固定板５を空気調和機に用いることによって、室内熱交換器２の側面部近傍の結露水の飛散を確実に防止できる空気調和機を実現できる。
【００３８】
上記実施の形態では、空気調和機の室内ユニットの室内熱交換器を底フレーム固定するための熱交換器固定板について説明したが、空気調和機の室内ユニットの室内熱交換器に限らず、冷凍機等の他の装置の熱交換器にこの発明を適用してもよい。
【００３９】
また、上記実施の形態では、段方向に隣接する２つのヘアピン部を略平行四辺形状の１つの挿入穴に挿入したが、列方向に隣接する２つのヘアピン部を１つの挿入穴に挿入してもよいし、段方向かつ列方向に隣接するヘアピン部を組み合わせた複数のヘアピン部を１つの挿入穴に挿入してもよい。
【００４０】
また、上記実施の形態では、上記室内熱交換器２の側面に管板１５〜１８を取り付けたが、管板はなくてもよい。
【００４１】
また、この発明の熱交換器固定板は、上記実施の形態に限るものではなく、例えば、挿入穴,壁部,リブおよび流路の位置,形状などは、熱交換器の側面部の形状等に応じて適宜設定すればよい。
【００４２】

Therefore, the claims 3 According to the heat exchanger fixing plate of the present invention, the dew formed on the inner side of the wall portion by the groove portion formed on the inner side and the rear surface side of the wall portion causes the dew condensation water generated on the inner side of the wall portion to be on the rear side (the side portion of the heat exchanger). To the outer side of the wall part and the ribs standing on the surface side of the plate-like base so that one end is connected to the lower side of the wall part. Further, the condensed water produced on the side surface of the outer edge of the discontinuous plate-like base is guided inward and downward from the outer edge by a flow channel formed on the surface side of the plate-like base. By guiding and accumulating the condensed water guided to the groove, rib and flow path in a drain pan or the like, the condensed water can be reliably treated, and the plate-like base can be reinforced by the rib.

Claims 4 The heat exchanger fixing plate according to the present invention is the second aspect. Or 3 In the heat exchanger fixing plate according to any one of the above, the height of the rib is gradually decreased from one end connected to the outside and the lower side of the wall portion toward the other end to thereby increase the outside of the wall portion. Since the condensed water generated at the tip is gradually guided to the surface of the plate-like base portion, it is possible to more reliably prevent the condensed water from scattering.

Claims 5 The air conditioner of the invention of claim 1 to claim 1 4 Any one of the heat exchanger fixing plates is used.
[0054]
Therefore, the claims 5 According to the air conditioner of the invention, by using the heat exchanger fixing plate that reliably processes the condensed water, the heat exchange is performed while preventing the intake air from flowing into the fan chamber without passing through the heat exchanger. It is possible to realize an air conditioner that can reliably prevent the condensation water from scattering near the side surface of the vessel.
