Description

本発明は、床置き式空気調和機に関し、特に熱交換器から出たドレイン（排水）が電気部品等に掛かることがなく、また製造コストの低い床置き式空気調和機に関する。   The present invention relates to a floor-standing air conditioner, and more particularly to a floor-standing air conditioner in which a drain (drainage) from a heat exchanger is not applied to an electrical component or the like and has a low manufacturing cost.

床置き式空気調和機では、ドレインパン（排水の受け皿）の排水口がつまった場合等に、ドレインパンより水が溢れ出してしまうことがある。従来の床置き式空気調和機では、このような場合に、ドレインパンの下方に配置された電気部品等に水が掛からないように、安全性確保のためのシールを電気部品収納箱の外郭に設けて水の浸入を防止する対策を施していた。   In a floor-mounted air conditioner, water may overflow from the drain pan when the drain port of the drain pan (drainage tray) is clogged. In such a floor-standing air conditioner, in such a case, a seal for ensuring safety is provided on the outer shell of the electrical component storage box so that water does not splash on the electrical components disposed below the drain pan. A measure was taken to prevent water from entering.

また従来の空気調和機の室内機では、熱交換器の下部の吹出口の天板を兼用する露受皿を設け、露受皿のリブの上端中央に設けられた凹部から溢水を流下させる一方、この凹部の下方に位置する露受皿先端部の低位置に設けられた通水孔から溢水を吹出口の前方に滴下させていた（例えば、特許文献１参照）。
特開平９−７２５６８号公報（図１、図２、図３） In addition, in a conventional air conditioner indoor unit, a dew tray that also serves as a top plate of the blower outlet at the lower part of the heat exchanger is provided, and overflow water flows down from a recess provided at the center of the upper end of the rib of the dew plate. Overflowing water was dripped in front of the air outlet from a water passage hole provided at a low position of the tip of the dew pan located below the recess (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 9-72568 (FIGS. 1, 2, and 3)

しかし従来の床置き式空気調和機では、一般的にドレインパンの縁が同じ高さであるため、水が溢れ出す位置が本体ユニットの据え付け状態による傾きや、製品の組立バラツキ等によって変化してしまい、水がどこから溢れ出すか予測ができなかった。このため電気部品収納箱の外郭は、どこから水が溢れ出ても水分が浸入しないように厳重にシールする必要が有り、このシール材が製造コストを増加させる原因となっていた。   However, in conventional floor-mounted air conditioners, the edge of the drain pan is generally the same height, so the position where the water overflows changes depending on the inclination of the main unit installation state, product assembly variations, etc. I couldn't predict where the water would overflow. For this reason, the outer shell of the electrical component storage box needs to be tightly sealed so that water does not enter wherever water overflows, and this sealing material increases the manufacturing cost.

また従来の空気調和機の室内機では（例えば、特許文献１参照）、露受皿先端部の低位置に設けられた通水孔から溢水を吹出口の前方に滴下させて、使用者が溢水を早期に発見できるようにしているものの、溢水は空気調和機の外部に滴下するため、衛生的に問題があり、また滴下した溢水を清掃しなければならない等の問題点があった。   Further, in a conventional air conditioner indoor unit (see, for example, Patent Document 1), overflowing water is dripped in front of the air outlet from a water passage hole provided at a low position of the tip of the dew tray, and the user overflows the water. Although it was made possible to detect it at an early stage, the overflowing water dropped outside the air conditioner, so there was a problem in terms of hygiene, and the dripping overflow had to be cleaned.

本発明は、上記のような問題がなく、電気部品等に水が掛からないようにして安全性を確保することができ、また収容箱をシールするシール材が不要で製造コストを抑制できる床置き式空気調和機を提供することを目的とする。   The present invention eliminates the above-mentioned problems, can ensure safety by preventing water from splashing on electrical components, etc., and does not require a sealing material that seals the storage box, and can suppress the manufacturing cost. It aims at providing a type air conditioner.

本発明に係る床置き式空気調和機は、熱交換器と、該熱交換器の下部に設けられ、熱交換器から発生したドレインを収容するドレインパンと、熱交換器から発生した冷風又は温風を前面下方に設けられた吹出口から送風するための送風ファンと、ドレインパンの下部に設けられ送風ファンを収容するファンケーシングと、前記ドレインパンの直下で床置き式空気調和機の前面側に設けられ、前記熱交換器及び前記送風ファンを制御する電気部品とを備え、ドレインパンが、床置き式空気調和機本体の背面側に形成された切り欠き状の溢流口を有し、ファンケーシングが、前記ファンケーシングの側面を凹状に加工して形成され溢流口から溢れ出た水を流下させる水路を有するものである。 The floor-standing air conditioner according to the present invention includes a heat exchanger, a drain pan provided in a lower portion of the heat exchanger, and containing a drain generated from the heat exchanger, and a cold air or a temperature generated from the heat exchanger. A blower fan for blowing air from an outlet provided below the front surface, a fan casing provided at the lower part of the drain pan and containing the blower fan, and the front side of the floor-mounted air conditioner directly under the drain pan An electrical part that controls the heat exchanger and the blower fan , and the drain pan has a notch-shaped overflow port formed on the back side of the floor-standing air conditioner body , The fan casing has a water channel that is formed by processing the side surface of the fan casing into a concave shape and allows water that has overflowed from the overflow port to flow down.

本発明に係る床置き式空気調和機は、ドレインパンが切り欠き状の溢流口を有し、ファンケーシングが溢流口から溢れ出た水を流下させる水路を有するため、ドレインパンの下部に設けられた電気部品や送風ファンへの水着を防止することができ、水に対する安全性が確保できる。また水の浸入を防止するための電気部品収容箱に貼付されたシール材を省略することができるため、コストが抑えられ安価な床置き式空気調和機を提供することが可能となる。   In the floor-mounted air conditioner according to the present invention, the drain pan has a notch-like overflow port, and the fan casing has a water channel for flowing down the water overflowing from the overflow port. It is possible to prevent the swimsuit from being provided on the provided electrical parts and the blower fan, and to ensure safety against water. Moreover, since the sealing material affixed to the electrical component storage box for preventing water from entering can be omitted, it is possible to provide an inexpensive floor-standing air conditioner with reduced cost.

In the first embodiment, an electrical component storage box 4 that stores electrical components directly below the drain pan 3 is provided. This electrical component is for controlling the heat exchanger 2 and the blower fan 5 shown below.

さらにドレインパン３の下部には、熱交換器２から発生した冷風又は温風を送風するための送風ファン５を収容するファンケーシング６が備えられている。なお本実施形態１では、図１に示すように、電気部品収容箱４が床置き式空気調和機本体１内部の前面側に設けられ、ファンケーシング６が床置き式空気調和機本体１内部の背面側に設けられているものとする。また、床置き式空気調和機本体１の最下部には、底面を形成するベース７が設けられている。なお送風ファン５は、例えば電動モータにより回転して熱交換器２から発生した冷風又は温風を送風するようになっている。   Furthermore, a fan casing 6 that houses a blower fan 5 for blowing cold air or hot air generated from the heat exchanger 2 is provided below the drain pan 3. In the first embodiment, as shown in FIG. 1, the electrical component storage box 4 is provided on the front side inside the floor-standing air conditioner body 1, and the fan casing 6 is inside the floor-standing air conditioner body 1. It is provided on the back side. A base 7 that forms a bottom surface is provided at the bottom of the floor-standing air conditioner body 1. The blower fan 5 is rotated by, for example, an electric motor and blows cold air or hot air generated from the heat exchanger 2.

図１に示す床置き式空気調和機は、床置き式空気調和機本体１の前面上方に設けられた吸込口（符号なし）から送風ファン５によって空気を吸引し、その空気が熱交換器２を通過する。この際、熱交換器２は空気を冷却又は加熱することにより冷風又は温風を発生する。熱交換器２で発生した冷風又は温風は、送風ファン５によって床置き式空気調和機本体１の前面下方に設けられた吹出口（符号なし）から送風される。   The floor-standing air conditioner shown in FIG. 1 sucks air by a blower fan 5 from a suction port (not indicated) provided above the front surface of the floor-standing air conditioner body 1, and the air is the heat exchanger 2. Pass through. At this time, the heat exchanger 2 generates cold air or hot air by cooling or heating the air. Cold air or warm air generated in the heat exchanger 2 is blown by a blower fan 5 from an air outlet (not indicated) provided below the front surface of the floor-standing air conditioner body 1.

図２に示すように、本実施形態１に係る床置き式空気調和機のドレインパン３の底面には、排水口３ａが設けられており、この排水口３ａにはドレインホース８が接続されている。またドレインパン３の側壁の上方には、切り欠き状の溢水口３ｂが設けられている。なお本実施形態１では、溢水口３ｂは床置き式空気調和機本体１の背面側に設けられているものとする。また溢水口３ｂの切り欠きの形状は、任意の形状でよい。
またファンケーシング６の側面には、ファンケーシング６を凹状に加工した水路６ａが形成されており、この水路６ａはドレインパン３に設けられた溢水口３ｂと繋がるように配置されている。なお従来の一般的な床置き式空気調和機では、溢水口３ｂ及び水路６ａに相当するものは設けられていない。 As shown in FIG. 2, a drain port 3a is provided on the bottom surface of the drain pan 3 of the floor-standing air conditioner according to the first embodiment, and a drain hose 8 is connected to the drain port 3a. Yes. Further, a notch-like overflow port 3 b is provided above the side wall of the drain pan 3. In the first embodiment, the overflow port 3b is provided on the back side of the floor-standing air conditioner body 1. Moreover, the shape of the notch of the overflow port 3b may be any shape.
Further, a water channel 6 a formed by processing the fan casing 6 into a concave shape is formed on the side surface of the fan casing 6, and the water channel 6 a is disposed so as to be connected to the overflow port 3 b provided in the drain pan 3. In addition, in the conventional general floor-standing air conditioner, the thing equivalent to the overflow port 3b and the water channel 6a is not provided.

本実施形態１に係る床置き式空気調和機では、床置き式空気調和機本体１の内部上方に備えられた熱交換器２から発生したドレインが、熱交換器２の下部に設けられたドレインパン３に流下する。通常の場合、ドレインパン３に流下したドレインは、排水口３ａからドレインホース８を通って床置き式空気調和機本体１の外部に排出される。
しかし、排水口３ａやドレインホース８に詰まりが発生した場合には、ドレインパン３に水（ドレイン）が溜まり、この水がドレインパン３に設けられた溢水口３ｂから流出する。流出した水は、ファンケーシンング６の側面に凹状に形成された水路６ａに沿って流下し、床置き式空気調和機本体１の最下部を形成するベース７に流れ落ちる。 In the floor-standing air conditioner according to the first embodiment, the drain generated from the heat exchanger 2 provided in the upper part of the floor-standing air conditioner body 1 is provided at the lower portion of the heat exchanger 2. Flow down into pan 3. In a normal case, the drain that has flowed down to the drain pan 3 is discharged from the drain port 3 a through the drain hose 8 to the outside of the floor-standing air conditioner body 1.
However, when the drain port 3 a or the drain hose 8 is clogged, water (drain) is accumulated in the drain pan 3, and this water flows out from the overflow port 3 b provided in the drain pan 3. The water that has flowed out flows down along the water channel 6a formed in a concave shape on the side surface of the funcaging 6, and then flows down to the base 7 that forms the lowest part of the floor-standing air conditioner body 1.

なお本実施形態１では、電気部品を収容する電気部品収容箱４が床置き式空気調和機本体１の前面側に設けられ、溢水口３ｂが床置き式空気調和機本体１の背面側に設けられているが、電気部品を収容する電気部品収容箱４を床置き式空気調和機本体１の背面側に設け、溢水口３ｂを床置き式空気調和機本体１の前面側に設けるようにしてもよい。このように、溢水口３ｂと電気部品を収容する電気部品収容箱４を離れた位置に配置することで、電気部品への水着を確実に防止することができる。   In the first embodiment, the electrical component storage box 4 that stores electrical components is provided on the front side of the floor-standing air conditioner body 1, and the overflow port 3 b is provided on the back side of the floor-standing air conditioner body 1. However, an electrical component storage box 4 for storing electrical components is provided on the back side of the floor-standing air conditioner body 1 and an overflow port 3b is provided on the front side of the floor-standing air conditioner body 1.

In this manner, by arranging the overflow port 3b and the electrical component storage box 4 that stores electrical components at positions separated from each other, it is possible to reliably prevent the bathing of the electrical components.

本実施形態１では、ドレインパン３が切り欠き状の溢流口３ｂを有し、ファンケーシング６が溢流口３ｂから溢れ出た水を流下させる水路６ａを有するため、ドレインパン３の下部に設けられた電気部品や送風ファン６への水着を防止することができ、水に対する安全性が確保できる。また水の浸入を防止するための電気部品収容箱４に貼付されたシール材を省略することができるため、コストが抑えられ安価な床置き式空気調和機を提供することが可能となる。
また、溢水口３ｂから溢れ出た水を流下させる水路６ａがファンケーシング６の側面に凹状に形成されているため、溢水口３ｂから溢れ出た水がファンケーシング６の側面に沿って流下し、水が送風ファン５に掛かるのを防止することができる。
さらに電気部品収容箱４がドレインパン３の直下に設けられているため、溢水口３ｂから溢れ出た水が電気部品に掛かる危険性を低減することができる。 In the first embodiment, the drain pan 3 has a notch-like overflow port 3b, and the fan casing 6 has a water channel 6a for flowing water overflowing from the overflow port 3b. Swimsuits on the provided electrical components and the blower fan 6 can be prevented, and safety against water can be ensured. Moreover, since the sealing material affixed to the electrical component storage box 4 for preventing water from entering can be omitted, it is possible to provide an inexpensive floor-standing air conditioner with reduced costs.
Further, since the water channel 6a for flowing down the water overflowing from the overflow port 3b is formed in a concave shape on the side surface of the fan casing 6, the water overflowing from the overflow port 3b flows down along the side surface of the fan casing 6, It is possible to prevent water from splashing on the blower fan 5.
Furthermore, since the electrical component storage box 4 is provided directly below the drain pan 3, it is possible to reduce the risk that the water overflowing from the overflow port 3b is applied to the electrical component.

なお本発明に係る床置き式空気調和機は、上記の実施形態に限定されるものではなく、本発明の思想の範囲内において変更することが可能である。例えば、ファンケーシング６に設けられた水路６ａは、ホース状のものであってもよい。   The floor-standing air conditioner according to the present invention is not limited to the above-described embodiment, and can be changed within the scope of the idea of the present invention. For example, the water channel 6a provided in the fan casing 6 may be a hose.
