Description

本発明は、室内ユニットにおける結露水の処理をすることができる空気調和機に関するものである。   The present invention relates to an air conditioner capable of treating condensed water in an indoor unit.

従来の空気調和機においては、熱交換器は台枠を介して室内ユニットに取り付けられているが、熱交換器が台枠から浮き上がると熱交換されていない空気が室内に吹き出されることから、熱交換器が台枠から浮き上がらないように構成することで熱交換性能を向上させている（例えば、特許文献１参照）。   In the conventional air conditioner, the heat exchanger is attached to the indoor unit through the frame, but when the heat exchanger is lifted from the frame, air that is not heat exchanged is blown out into the room, The heat exchange performance is improved by configuring the heat exchanger so that it does not rise from the underframe (see, for example, Patent Document 1).

熱交換器の台枠への取付構造について図９及び図１０を参照しながら詳述する。図９は従来の空気調和機の室内ユニットに設けられた熱交換器とその台枠の分解斜視図であり、図１０はその部分分解斜視図である。   A structure for mounting the heat exchanger to the frame will be described in detail with reference to FIGS. 9 and 10. FIG. 9 is an exploded perspective view of a heat exchanger and its underframe provided in an indoor unit of a conventional air conditioner, and FIG. 10 is a partially exploded perspective view thereof.

図９及び図１０に示されるように、熱交換器１０１は、その端部を形成する左右一対の端板１０５ａ，１０５ｂを有し、一方の端板１０５ａには突起１０６ａが形成される一方、他方の端板１０５ｂには孔部１０４ｂが形成されている。また、熱交換器１０１を室内ユニットに取り付けるための台枠１０２は、熱交換器１０１の幅とほぼ等しい幅で立設された一対の取付板１０３ａ，１０３ｂを有し、一方の取付板１０３ａには孔部１０４ａが形成される一方、他方の取付板１０３ｂには突起１０６ｂが形成されている。   As shown in FIGS. 9 and 10, the heat exchanger 101 has a pair of left and right end plates 105a and 105b that form end portions thereof, while one end plate 105a has a protrusion 106a, A hole 104b is formed in the other end plate 105b. In addition, the frame 102 for attaching the heat exchanger 101 to the indoor unit has a pair of mounting plates 103a and 103b erected with a width substantially equal to the width of the heat exchanger 101, and one mounting plate 103a includes While the hole 104a is formed, a projection 106b is formed on the other mounting plate 103b.

熱交換器１０１を室内ユニット内に取り付ける場合には、熱交換器端板１０５ａの突起１０６ａを対応する取付板１０３ａの孔部１０４ａに嵌入させるとともに、取付板１０３ｂの突起１０６ｂを対応する熱交換器端板１０５ｂの孔部１０４ｂに嵌入させている。   When mounting the heat exchanger 101 in the indoor unit, the protrusion 106a of the heat exchanger end plate 105a is fitted into the hole 104a of the corresponding mounting plate 103a, and the protrusion 106b of the mounting plate 103b is inserted into the corresponding heat exchanger. It is made to fit in the hole 104b of the end plate 105b.

しかしながら、従来の構成では、熱交換器端板１０５ａの突起１０６ａと取付板１０３ａの孔部１０４ａとが係合するため、突起１０６ａの先端部は送風回路の内側に位置することになり、突起１０６ａの先端部に生じた結露水が送風回路に侵入し、送風回路を通じて空気調和機の吹き出し口から漏れ出て、水が飛んだり滴下する恐れがあるという課題を有していた。   However, in the conventional configuration, since the protrusion 106a of the heat exchanger end plate 105a and the hole 104a of the mounting plate 103a are engaged, the tip of the protrusion 106a is positioned inside the air blowing circuit, and the protrusion 106a. Condensed water generated at the front end of the air enters the blower circuit, leaks from the blowout port of the air conditioner through the blower circuit, and has a problem that water may fly or drop.

本発明は、従来技術の有するこのような問題点に鑑みてなされたものであり、簡素な構成で突起先端に生じた結露水を円滑にドレンパンに導くことにより吹き出し口からの水の漏洩を防止することができる空気調和機を提供することを目的としている。   The present invention has been made in view of such problems of the prior art, and prevents the leakage of water from the outlet by smoothly guiding the condensed water generated at the tip of the protrusion to the drain pan with a simple configuration. It aims to provide an air conditioner that can be used.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

図１は本発明に係る空気調和機の室内ユニットの縦断面図であり、図２はこの室内ユニットに設けられた熱交換器とその台枠の分解斜視図である。   FIG. 1 is a longitudinal sectional view of an indoor unit of an air conditioner according to the present invention, and FIG. 2 is an exploded perspective view of a heat exchanger and its frame provided in the indoor unit.

図１に示されるように、本発明に係る空気調和機の室内ユニット１の内部には、熱交換器２と、室内空気を熱交換器２に通風させるためにクロスフローファン７とが設けられている。空気調和機の運転中は、クロスフローファン７が動作することにより、吸込みグリル８より吸込まれた室内空気が熱交換器２を通過し冷媒と熱交換し、熱交換した調和空気が吹き出し口１０より室内に吹き出すように構成されている。   As shown in FIG. 1, a heat exchanger 2 and a crossflow fan 7 are provided inside the indoor unit 1 of the air conditioner according to the present invention to allow the indoor air to flow through the heat exchanger 2. ing. During the operation of the air conditioner, the cross flow fan 7 is operated so that the indoor air sucked from the suction grill 8 passes through the heat exchanger 2 and exchanges heat with the refrigerant, and the heat-conditioned conditioned air is discharged from the outlet 10. It is configured to blow out more indoors.

また、熱交換器２の下方には、熱交換器２で発生した結露水を溜め、外部へ導出するドレンホースに導くためのドレンパン９が設けられている。   In addition, a drain pan 9 is provided below the heat exchanger 2 for collecting condensed water generated in the heat exchanger 2 and leading it to a drain hose that leads to the outside.

図２に示されるように、熱交換器２は、その端部を形成する左右一対の端板４ａ，４ｂを有し、一方の端板４ａには突起６ａが形成される一方、他方の端板４ｂには孔部５ｂが形成されている。熱交換器２は台枠３を介して室内ユニットに取り付けられるが、この台枠３は、熱交換器２の幅とほぼ等しい幅で立設された一対の取付板３ａ，３ｂを有し、一方の取付板３ａには孔部５ａが形成される一方、他方の取付板３ｂには突起６ｂが形成されている。   As shown in FIG. 2, the heat exchanger 2 has a pair of left and right end plates 4a and 4b that form the ends thereof, and one end plate 4a has a protrusion 6a formed on the other end. A hole 5b is formed in the plate 4b. The heat exchanger 2 is attached to the indoor unit via the frame 3, and this frame 3 has a pair of mounting plates 3 a and 3 b erected with a width substantially equal to the width of the heat exchanger 2, A hole 5a is formed in one mounting plate 3a, while a protrusion 6b is formed in the other mounting plate 3b.

熱交換器２を室内ユニットに取り付けるに際し、熱交換器端板４ａの突起６ａを対応する取付板３ａの孔部５ａに嵌入させるとともに、取付板３ｂの突起６ｂを対応する熱交換器端板４ｂの孔部５ｂに嵌入させることにより、熱交換器端板４ａ，４ｂが台枠２に設けられた左右一対の取付板３ａ，３ｂにしっかりと固定される。   When attaching the heat exchanger 2 to the indoor unit, the projection 6a of the heat exchanger end plate 4a is fitted into the hole 5a of the corresponding mounting plate 3a, and the projection 6b of the mounting plate 3b is fitted to the corresponding heat exchanger end plate 4b. The heat exchanger end plates 4a and 4b are firmly fixed to the pair of left and right mounting plates 3a and 3b provided on the frame 2 by being fitted into the holes 5b.

図３及び図４は取付板３ａの先端部を示しており、両図に示されるように、取付板３ａにおける孔部５ａの下方には、取付板３ａの端面よりほぼ垂直に延びる水受けリブ９０が形成されている。この水受けリブ９０は、突起６ａに生じる結露水をドレンパン９に誘導するための水受け誘導手段として作用し、結露水をドレンパン９に誘導できる形状であれば、図４に示される形状以外の形状でもよい。   3 and 4 show the tip of the mounting plate 3a, and as shown in both figures, below the hole 5a in the mounting plate 3a, a water receiving rib extending substantially perpendicularly from the end surface of the mounting plate 3a. 90 is formed. The water receiving rib 90 acts as a water receiving guiding means for guiding the condensed water generated in the protrusion 6a to the drain pan 9, and can have a shape other than the shape shown in FIG. 4 as long as the condensed water can be guided to the drain pan 9. Shape may be sufficient.

このように、水受けリブ９０を設けることで、冷房運転時に突起６ａの先端が結露しても、水受けリブ９０により結露水はドレンパン９に円滑に処理されるので、結露水が送風回路を通じて吹き出し口１０から漏れ出て、水が飛んだり滴下するという事態を回避できる。なお、送風回路とは、吸込みグリル８より吸込まれ、熱交換器２を通過し、クロスフローファン７にて吹き出し口１０から吹き出す空気の流れのことである。   In this way, by providing the water receiving rib 90, even if the tip of the protrusion 6a is condensed during cooling operation, the condensed water is smoothly processed by the drain pan 9 by the water receiving rib 90. It is possible to avoid a situation in which water leaks out and drops from the outlet 10. The blower circuit is a flow of air that is sucked from the suction grill 8, passes through the heat exchanger 2, and is blown out from the outlet 10 by the cross flow fan 7.

図５は水受けリブ９０の変形例を示しており、突起６ａの下方に設けられた水受けリブ９０は前方に向かって下方に傾斜しており、水受けリブ９０に滴下した結露水をドレンパン９に確実に導くことができる。   FIG. 5 shows a modified example of the water receiving rib 90. The water receiving rib 90 provided below the protrusion 6a is inclined downward toward the front, and the dew condensate dripped onto the water receiving rib 90 is drained. 9 can be surely guided.

図６は水受けリブ９０の別の変形例を示しており、図５に示されるように傾斜した水受けリブ９０の後縁を孔部５ａよりも後方に位置させることで、突起６ａから滴下する水を確実に受けることができ、結露水が吹き出し口１０から漏れ出ることを防止することができる。   FIG. 6 shows another modification of the water receiving rib 90. As shown in FIG. 5, the rear edge of the inclined water receiving rib 90 is positioned behind the hole 5a, so that the water receiving rib 90 is dropped from the protrusion 6a. Thus, it is possible to reliably receive the water to be condensed, and to prevent the condensed water from leaking from the outlet 10.

図７は水受けリブ９０のさらに別の変形例を示しており、傾斜した水受けリブ９０の後縁を、孔部５ａの後方でその下端よりも上方に位置させることで、突起６ａから滴下する水をさらに確実に受けることができ、結露水が吹き出し口１０から漏れ出ることを防止することができる。   FIG. 7 shows still another modified example of the water receiving rib 90. The rear edge of the inclined water receiving rib 90 is positioned behind the hole 5a and above the lower end thereof, thereby dropping from the protrusion 6a. The water to be received can be received more reliably, and the condensed water can be prevented from leaking from the outlet 10.

図８は水受けリブ９０のさらに別の変形例を示しており、傾斜した水受けリブ９０の前縁を孔部５ａよりも前方に位置させることで、突起６ａから滴下する水をさらに確実に受けることができ、結露水が吹き出し口１０から漏れ出ることを防止することができる。   FIG. 8 shows still another modified example of the water receiving rib 90. By positioning the front edge of the inclined water receiving rib 90 in front of the hole 5a, water dripped from the protrusion 6a can be more reliably obtained. It is possible to prevent the condensed water from leaking out from the outlet 10.

以上のように、結露水をドレンパンに誘導する形状とした水受けリブを取付板３ａの先端に配設することで、送風回路への結露水の侵入を防止することができるので、さまざまな形態の空気調和機に適用できる。   As described above, it is possible to prevent the intrusion of the dew condensation water into the blower circuit by disposing the water receiving rib having a shape for guiding the dew condensation water to the drain pan at the tip of the mounting plate 3a. Applicable to any air conditioner.

本発明は、室内ユニットにおける結露水の処理をすることができる空気調和機に関するものである。   The present invention relates to an air conditioner capable of treating condensed water in an indoor unit.

従来の空気調和機においては、熱交換器は台枠を介して室内ユニットに取り付けられているが、熱交換器が台枠から浮き上がると熱交換されていない空気が室内に吹き出されることから、熱交換器が台枠から浮き上がらないように構成することで熱交換性能を向上させている（例えば、特許文献１参照）。   In the conventional air conditioner, the heat exchanger is attached to the indoor unit through the frame, but when the heat exchanger is lifted from the frame, air that is not heat exchanged is blown out into the room, The heat exchange performance is improved by configuring the heat exchanger so that it does not rise from the underframe (see, for example, Patent Document 1).

熱交換器の台枠への取付構造について図９及び図１０を参照しながら詳述する。図９は従来の空気調和機の室内ユニットに設けられた熱交換器とその台枠の分解斜視図であり、図１０はその部分分解斜視図である。   A structure for mounting the heat exchanger to the frame will be described in detail with reference to FIGS. 9 and 10. FIG. 9 is an exploded perspective view of a heat exchanger and its underframe provided in an indoor unit of a conventional air conditioner, and FIG. 10 is a partially exploded perspective view thereof.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

図１は本発明に係る空気調和機の室内ユニットの縦断面図であり、図２はこの室内ユニットに設けられた熱交換器とその台枠の分解斜視図である。   FIG. 1 is a longitudinal sectional view of an indoor unit of an air conditioner according to the present invention, and FIG. 2 is an exploded perspective view of a heat exchanger and its frame provided in the indoor unit.

図１に示されるように、本発明に係る空気調和機の室内ユニット１の内部には、熱交換器２と、室内空気を熱交換器２に通風させるためにクロスフローファン７とが設けられている。空気調和機の運転中は、クロスフローファン７が動作することにより、吸込みグリル８より吸込まれた室内空気が熱交換器２を通過し冷媒と熱交換し、熱交換した調和空気が吹き出し口１０より室内に吹き出すように構成されている。   As shown in FIG. 1, a heat exchanger 2 and a crossflow fan 7 are provided inside the indoor unit 1 of the air conditioner according to the present invention to allow the indoor air to flow through the heat exchanger 2. ing. During the operation of the air conditioner, the cross flow fan 7 is operated so that the indoor air sucked from the suction grill 8 passes through the heat exchanger 2 and exchanges heat with the refrigerant, and the heat-conditioned conditioned air is discharged from the outlet 10. It is configured to blow out more indoors.

また、熱交換器２の下方には、熱交換器２で発生した結露水を溜め、外部へ導出するドレンホースに導くためのドレンパン９が設けられている。   In addition, a drain pan 9 is provided below the heat exchanger 2 for collecting condensed water generated in the heat exchanger 2 and leading it to a drain hose that leads to the outside.

図２に示されるように、熱交換器２は、その端部を形成する左右一対の端板４ａ，４ｂを有し、一方の端板４ａには突起６ａが形成される一方、他方の端板４ｂには孔部５ｂが形成されている。熱交換器２は台枠３を介して室内ユニットに取り付けられるが、この台枠３は、熱交換器２の幅とほぼ等しい幅で立設された一対の取付板３ａ，３ｂを有し、一方の取付板３ａには孔部５ａが形成される一方、他方の取付板３ｂには突起６ｂが形成されている。   As shown in FIG. 2, the heat exchanger 2 has a pair of left and right end plates 4a and 4b that form the ends thereof, and one end plate 4a has a protrusion 6a formed on the other end. A hole 5b is formed in the plate 4b. The heat exchanger 2 is attached to the indoor unit via the frame 3, and this frame 3 has a pair of mounting plates 3 a and 3 b erected with a width substantially equal to the width of the heat exchanger 2, A hole 5a is formed in one mounting plate 3a, while a protrusion 6b is formed in the other mounting plate 3b.

熱交換器２を室内ユニットに取り付けるに際し、熱交換器端板４ａの突起６ａを対応する取付板３ａの孔部５ａに嵌入させるとともに、取付板３ｂの突起６ｂを対応する熱交換器端板４ｂの孔部５ｂに嵌入させることにより、熱交換器端板４ａ，４ｂが台枠２に設けられた左右一対の取付板３ａ，３ｂにしっかりと固定される。   When attaching the heat exchanger 2 to the indoor unit, the projection 6a of the heat exchanger end plate 4a is fitted into the hole 5a of the corresponding mounting plate 3a, and the projection 6b of the mounting plate 3b is fitted to the corresponding heat exchanger end plate 4b. The heat exchanger end plates 4a and 4b are firmly fixed to the pair of left and right mounting plates 3a and 3b provided on the frame 2 by being fitted into the holes 5b.

図３及び図４は取付板３ａの先端部を示しており、両図に示されるように、取付板３ａにおける孔部５ａの下方には、取付板３ａの端面よりほぼ垂直に延びる水受けリブ９０が形成されている。この水受けリブ９０は、突起６ａに生じる結露水をドレンパン９に誘導するための水受け誘導手段として作用し、結露水をドレンパン９に誘導できる形状であれば、図４に示される形状以外の形状でもよい。   3 and 4 show the tip of the mounting plate 3a, and as shown in both figures, below the hole 5a in the mounting plate 3a, a water receiving rib extending substantially perpendicularly from the end surface of the mounting plate 3a. 90 is formed. The water receiving rib 90 acts as a water receiving guiding means for guiding the condensed water generated in the protrusion 6a to the drain pan 9, and can have a shape other than the shape shown in FIG. 4 as long as the condensed water can be guided to the drain pan 9. Shape may be sufficient.

このように、水受けリブ９０を設けることで、冷房運転時に突起６ａの先端が結露しても、水受けリブ９０により結露水はドレンパン９に円滑に処理されるので、結露水が送風回路を通じて吹き出し口１０から漏れ出て、水が飛んだり滴下するという事態を回避できる。なお、送風回路とは、吸込みグリル８より吸込まれ、熱交換器２を通過し、クロスフローファン７にて吹き出し口１０から吹き出す空気の流れのことである。   In this way, by providing the water receiving rib 90, even if the tip of the protrusion 6a is condensed during cooling operation, the condensed water is smoothly processed by the drain pan 9 by the water receiving rib 90. It is possible to avoid a situation in which water leaks out and drops from the outlet 10. The blower circuit is a flow of air that is sucked from the suction grill 8, passes through the heat exchanger 2, and is blown out from the outlet 10 by the cross flow fan 7.

図５は水受けリブ９０の変形例を示しており、突起６ａの下方に設けられた水受けリブ９０は前方に向かって下方に傾斜しており、水受けリブ９０に滴下した結露水をドレンパン９に確実に導くことができる。   FIG. 5 shows a modified example of the water receiving rib 90. The water receiving rib 90 provided below the protrusion 6a is inclined downward toward the front, and the dew condensate dripped onto the water receiving rib 90 is drained. 9 can be surely guided.

図６は水受けリブ９０の別の変形例を示しており、図５に示されるように傾斜した水受けリブ９０の後縁を孔部５ａよりも後方に位置させることで、突起６ａから滴下する水を確実に受けることができ、結露水が吹き出し口１０から漏れ出ることを防止することができる。   FIG. 6 shows another modification of the water receiving rib 90. As shown in FIG. 5, the rear edge of the inclined water receiving rib 90 is positioned behind the hole 5a, so that the water receiving rib 90 is dropped from the protrusion 6a. Thus, it is possible to reliably receive the water to be condensed, and to prevent the condensed water from leaking from the outlet 10.

図７は水受けリブ９０のさらに別の変形例を示しており、傾斜した水受けリブ９０の後縁を、孔部５ａの後方でその下端よりも上方に位置させることで、突起６ａから滴下する水をさらに確実に受けることができ、結露水が吹き出し口１０から漏れ出ることを防止することができる。   FIG. 7 shows still another modified example of the water receiving rib 90. The rear edge of the inclined water receiving rib 90 is positioned behind the hole 5a and above the lower end thereof, thereby dropping from the protrusion 6a. The water to be received can be received more reliably, and the condensed water can be prevented from leaking from the outlet 10.

図８は水受けリブ９０のさらに別の変形例を示しており、傾斜した水受けリブ９０の前縁を孔部５ａよりも前方に位置させることで、突起６ａから滴下する水をさらに確実に受けることができ、結露水が吹き出し口１０から漏れ出ることを防止することができる。   FIG. 8 shows still another modified example of the water receiving rib 90. By positioning the front edge of the inclined water receiving rib 90 in front of the hole 5a, water dripped from the protrusion 6a can be more reliably obtained. It is possible to prevent the condensed water from leaking out from the outlet 10.

以上のように、結露水をドレンパンに誘導する形状とした水受けリブを取付板３ａの先端に配設することで、送風回路への結露水の侵入を防止することができるので、さまざまな形態の空気調和機に適用できる。   As described above, it is possible to prevent the intrusion of the dew condensation water into the blower circuit by disposing the water receiving rib having a shape for guiding the dew condensation water to the drain pan at the tip of the mounting plate 3a. Applicable to any air conditioner.
