Abstract

<P>PROBLEM TO BE SOLVED: To prevent dew condensation on an outer wall of a drain pan due to flowing of condensed water between the drain pan and a foam heat insulating material for the drain pan and to reduce work man-hours since the drain pan is cooled to generate dew condensation on the outer wall of the drain pan when the condensed water enters between the drain pan and the foam heat insulating material for the drain pan, and an easy method having less work processes is required as a means to solve the generation. <P>SOLUTION: A foaming multiplication rate of the foam heat insulating material for the drain pan is made lower. Only drain pan discharge port for discharging the condensed water and foam heat insulating material discharge port for the drain pan are adhered. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、空気調和機の室内ユニットのドレンパンの構造に関するものである。 The present invention relates to a drain pan structure of an indoor unit of an air conditioner.

近年、空気調和機の室内吐出空気の気流制御が複雑になるにつれて、室内機の吐出口に配置されるドレンパン外壁への露付きが多くなる傾向にある。そのため、断熱材の部品点数を低減するために、ドレンパンの内壁にドレンパン用発泡断熱材を取付けることが多くなっている。そのため、簡単にドレンパンの内壁にドレンパン用発泡断熱材を取付ける必要がある。 In recent years, as airflow control of indoor discharge air of an air conditioner becomes more complicated, there is a tendency that the dew on the drain pan outer wall arranged at the discharge port of the indoor unit increases. Therefore, in order to reduce the number of parts of the heat insulating material, a foamed heat insulating material for drain pan is often attached to the inner wall of the drain pan. For this reason, it is necessary to easily attach the foam heat insulating material for the drain pan to the inner wall of the drain pan.

従来の文献としては、ドレンパン外壁の露付き防止として、特許文献１が有る。 As a conventional document, there is Patent Document 1 as prevention of dew condensation on the drain pan outer wall.

しかしながら、ドレンパンとドレンパン用発泡断熱材の間に凝縮水が入り込むと、ドレンパンが冷されて、ドレンパン外壁に露付きが発生する。そのための解決手段として、容易で作業工程が少ない方法が必要となる。 However, when condensed water enters between the drain pan and the foam heat insulating material for the drain pan, the drain pan is cooled and dew is generated on the drain pan outer wall. As a solution for that, an easy method with few work steps is required.

そこで、本発明は容易で作業工程が少ない方法及び構造とすることを目的とする。 Accordingly, an object of the present invention is to provide a method and a structure that are easy and require few work steps.

上記課題を解決するため、ドレンパン用発泡断熱材の発泡倍率を低くし、凝縮水を排出させるドレンパン排出口とドレンパン用発泡断熱材排出口のみを接着させることを特徴とする。 In order to solve the above problem, the foaming heat insulating material for drain pan is made to have a low expansion ratio, and only the drain pan outlet for discharging condensed water and the foam insulating material outlet for drain pan are bonded.

本発明を行なうことにより、凝縮水がドレンパンとドレンパン用発泡断熱材の間に流れ込んでドレンパンの外壁に露付きすることを防止すること及び作業工数を低減させることができる。 By carrying out the present invention, it is possible to prevent the condensed water from flowing between the drain pan and the foam insulating material for drain pan and being exposed to the outer wall of the drain pan, and to reduce the work man-hours.

第１の発明は、凝縮水がドレンパンとドレンパン用発泡断熱材の間に流れ込んでドレンパンの外壁に露付きすることを防止すること及び作業工数を低減させることを目的に、ドレンパン用発泡断熱材の発泡倍率を低くし、凝縮水を排出させるドレンパン排出口とドレンパン用発泡断熱材排出口のみを接着させる。 The first aspect of the present invention is to prevent the condensed water from flowing between the drain pan and the foam insulating material for the drain pan to be exposed to the outer wall of the drain pan and to reduce the work man-hours. The foaming ratio is lowered, and only the drain pan outlet for discharging condensed water and the foam insulating material outlet for drain pan are bonded.

図１は、本発明の第１の実施形態における空気調和機の側面の断面図を示すものである。 FIG. 1 is a side sectional view of an air conditioner according to a first embodiment of the present invention.

図１において、室内機のキャビネット１と化粧枠２と熱交換器３と上下風向ルーバー４と左右風向ルーバー５と室内送風ファン６とドレンパン７より構成される室内の空気調和機において、ドレンパン７の内壁に配置されるドレンパン用発泡断熱材８において、凝縮水９がドレンパン７とドレンパン用発泡断熱材８の間に流れ込むとドレンパン７の外壁に露付きすることがある。そのため、凝縮水９がドレンパン７とドレンパン用発泡断熱材８の間に流れ込まないようにする必要がある。 In FIG. 1, in an indoor air conditioner composed of an indoor unit cabinet 1, a decorative frame 2, a heat exchanger 3, an up / down air direction louver 4, a left / right air direction louver 5, an indoor fan 6, and a drain pan 7, In the foam insulation 8 for the drain pan disposed on the inner wall, when the condensed water 9 flows between the drain pan 7 and the foam insulation 8 for the drain pan, the outer wall of the drain pan 7 may be exposed. For this reason, it is necessary to prevent the condensed water 9 from flowing between the drain pan 7 and the foam insulating material 8 for the drain pan.

図２は、本発明の実施形態の概略図である。 FIG. 2 is a schematic diagram of an embodiment of the present invention.

ドレンパン７のドレンパン排出口１０にドレンパン用発泡断熱材８のドレンパン用発泡断熱材排出口１１が位置する。 The drain pan foam heat insulating material discharge port 11 of the drain pan foam heat insulating material 8 is positioned at the drain pan discharge port 10 of the drain pan 7.

熱交換器３から凝縮水９は、ドレンパン用発泡断熱材８に落ちる。その後、ドレンパン用発泡断熱材排出口１１を経由して、ドレンパン排出口１０からドレンホース１３へ行き、凝縮水９は、室外に排出される。 Condensed water 9 falls from the heat exchanger 3 to the foam insulation 8 for the drain pan. Thereafter, the water flows from the drain pan discharge port 10 to the drain hose 13 via the drain pan foam heat insulating material discharge port 11, and the condensed water 9 is discharged outside the room.

この時、ドレンパン用発泡断熱材排出口１１とドレンパン排出口１０の間に隙間があると、凝縮水９は、ドレンパン７とドレンパン用発泡断熱材８の間に流れ込み、ドレンパン７の外壁に露付きする。また、発泡素材を発泡すると、発泡ビーズの間に隙間が生じて、その隙間から凝縮水９がドレンパン７とドレンパン用発泡断熱材８の間に流れ込み、ドレンパン７の外壁に露付きする。 At this time, if there is a gap between the drain pan foam heat insulating material discharge port 11 and the drain pan discharge port 10, the condensed water 9 flows between the drain pan 7 and the drain pan foam heat insulating material 8 and is exposed to the outer wall of the drain pan 7. To do. Further, when the foam material is foamed, a gap is generated between the foam beads, and condensed water 9 flows between the drain pan 7 and the drain pan foam heat insulating material 8 from the gap, and is exposed to the outer wall of the drain pan 7.

本発明では、これを防止するために、ドレンパン用発泡断熱材８の発泡倍率を低くし、発泡ビーズの間の隙間を小さくすることにより、発泡ビーズの間への凝縮水９の侵入を防止し、凝縮水９を排出させるドレンパン排出口１０とドレンパン用発泡断熱材排出口１１のみを接着すれば、ドレンパン７とドレンパン用発泡断熱材８の間に流れ込みを防止し、ドレンパン７の外壁への露付を防ぐことが出来る。尚、発泡倍率は、２０倍以下とする必要がある。 In the present invention, in order to prevent this, the expansion ratio of the foam insulating material 8 for the drain pan is lowered, and the gap between the foam beads is reduced to prevent the condensed water 9 from entering between the foam beads. If only the drain pan discharge port 10 for discharging the condensed water 9 and the drain pan foam heat insulating material discharge port 11 are bonded, the flow between the drain pan 7 and the drain pan foam heat insulating material 8 is prevented, and the dew on the outer wall of the drain pan 7 is prevented. Can prevent sticking. The expansion ratio needs to be 20 times or less.
