Description

本発明は、ドレン水を排出する流水路を備えた空気調和装置の室内機に関するものである。   The present invention relates to an indoor unit of an air conditioner provided with a flow channel for discharging drain water.

空気調和装置の室内機には、冷房時等に熱交換器等にて凝縮したドレン水を集めて外部に排出するための流水路が設けられている。下記特許文献１及び２には、流水路を一方向に傾斜させてドレン水を排水する発明が開示されている。   The indoor unit of the air conditioner is provided with a flow channel for collecting drain water condensed by a heat exchanger or the like during cooling and discharging it to the outside. Patent Documents 1 and 2 below disclose an invention in which drain water is drained by inclining a flowing water channel in one direction.

国際公開第２０１５／１３６７１１号International Publication No. 2015/136711 特開２０１５−１０２２５７号公報Japanese Patent Laying-Open No. 2015-102257

しかし、室内機が傾いて据え付けられると、傾斜が急になった場合にはドレン水の流速が大きくなり流水路からドレン水が漏出するおそれがあり、傾斜が緩やかになった場合には排水が円滑に行われないおそれがある。   However, if the indoor unit is installed at an incline, the drain water flow rate will increase if the incline becomes steep, and the drain water may leak from the flow channel. There is a risk that it will not run smoothly.

本発明は、このような事情に鑑みてなされたものであって、流水路を流れる凝縮水の流速を適正に調整することができる空気調和装置の室内機を提供することを目的とする。   This invention is made | formed in view of such a situation, Comprising: It aims at providing the indoor unit of the air conditioning apparatus which can adjust the flow velocity of the condensed water which flows through a flowing water channel appropriately.

上記課題を解決するために、本発明の空気調和装置の室内機は以下の手段を採用する。
すなわち、本発明にかかる空気調和装置の室内機は、本体内にて凝縮した水を受けて排出する流水路を備え、前記流水路の底面には、該流水路の一部を遮る突起が設けられていることを特徴とする。 In order to solve the above problems, the indoor unit of the air conditioner of the present invention employs the following means.
That is, the indoor unit of the air conditioner according to the present invention includes a water flow channel that receives and discharges water condensed in the main body, and a projection that blocks a part of the water flow channel is provided on the bottom surface of the water flow channel. It is characterized by being.

室内機の内部で凝縮した水は流水路へと導かれ室内機の外部へと排出される。流水路の底面には、流水路の一部を遮る突起が設けられているので、流水路を流れる水の流速を調整することができる。例えば、流速が大きすぎて水が流水路を越えて漏出してしまうことを防止することができる。
突起は、水の流れ方向に所定間隔を有して複数設けることが好ましい。 The water condensed inside the indoor unit is led to the flow channel and discharged to the outside of the indoor unit. Since the bottom surface of the flow channel is provided with a projection that blocks a part of the flow channel, the flow velocity of the water flowing through the flow channel can be adjusted. For example, it is possible to prevent water from leaking beyond the flow channel due to the flow rate being too high.
It is preferable to provide a plurality of protrusions with a predetermined interval in the water flow direction.

さらに、本発明の空気調和装置の室内機では、前記底面は、長手方向の一方向に向かって全体が傾斜するとともに、該長手方向に直交する幅方向の一方向に向かって全体が傾斜することを特徴とする。   Furthermore, in the indoor unit of the air conditioner according to the present invention, the bottom surface is entirely inclined in one direction in the longitudinal direction, and is entirely inclined in one direction in the width direction orthogonal to the longitudinal direction. It is characterized by.

流水路の底面を長手方向の一方向に向かって全体を傾斜させるとともに、幅方向の一方向に向かって全体を傾斜させるようにしたので、流水路に流れ込んだ水は、長手方向に一方向に集められるとともに幅方向の一方向に集められる。したがって、底面に突起を設ける際に、水の流速を調整するために効果的な位置に設定することができる。   Since the entire bottom surface of the water channel is inclined in one direction in the longitudinal direction and the entire surface is inclined in one direction in the width direction, water flowing into the water channel is unidirectional in the longitudinal direction. Collected and collected in one direction in the width direction. Therefore, when the protrusion is provided on the bottom surface, it can be set at an effective position for adjusting the flow rate of water.

さらに、本発明の空気調和装置の室内機では、前記突起は、前記幅方向の前記一方向側に位置する壁部に接して設けられていることを特徴とする。   Furthermore, in the indoor unit for an air conditioner according to the present invention, the protrusion is provided in contact with a wall portion located on the one direction side in the width direction.

幅方向の一方向側に位置する壁部は、底部の幅方向において最も低い位置となるので水が集まる位置となる。この壁部に接するように突起を設けることで、効果的に水の流速を調整することができる。
突起は、壁部の延在方向に対して直交する方向に設けても良い。または、壁部の延在方向に対して直交する方向に対して所定角度傾斜させて延在させても突起部を設けても良い。水の流れ方向に向かうように突起を傾斜させると、突起による流れ抵抗が大きくなり流速をより低減できる。水の流速の低減効果を控えたい場合には、水の流れ方向に沿うように傾斜させて突起を設けると良い。 Since the wall portion located on one side in the width direction is the lowest position in the width direction of the bottom portion, it is a position where water collects. By providing the protrusion so as to be in contact with the wall, the flow rate of water can be adjusted effectively.
You may provide a protrusion in the direction orthogonal to the extension direction of a wall part. Alternatively, the protrusions may be provided even if they are inclined at a predetermined angle with respect to the direction orthogonal to the extending direction of the wall. When the protrusion is inclined so as to be directed in the water flow direction, the flow resistance due to the protrusion is increased, and the flow velocity can be further reduced. When it is desired to refrain from the effect of reducing the flow rate of water, it is preferable to provide protrusions that are inclined along the direction of water flow.

さらに、本発明の空気調和装置の室内機では、前記突起の中間位置に切欠が形成されていることを特徴とする。   Furthermore, the indoor unit of the air conditioner of the present invention is characterized in that a notch is formed at an intermediate position of the protrusion.

突起の中間位置に切欠を形成することで、切欠を水が通過する際に流速を低減することができる。この切欠の大きさを適宜変更することによって水の流速を調整することができる。   By forming the notch in the middle position of the protrusion, the flow rate can be reduced when water passes through the notch. The flow rate of water can be adjusted by appropriately changing the size of the notches.

さらに、本発明の空気調和装置の室内機では、前記突起は、タイル状に並べられていることを特徴とする。   Furthermore, in the indoor unit of the air conditioning apparatus of the present invention, the protrusions are arranged in a tile shape.

突起をタイル状に並べることで、突起間を流れる水の流速を低減することができる。突起間の間隔を適宜変更することによって水の流速を調整することができる。   By arranging the protrusions in a tile shape, the flow rate of water flowing between the protrusions can be reduced. The flow rate of water can be adjusted by appropriately changing the interval between the protrusions.

流水路の底面に流水路の一部を遮る突起を設けることとしたので、流水路を流れる凝縮水の流速を適正に調整することができる。   Since the projections that block a part of the flow channel are provided on the bottom surface of the flow channel, the flow rate of the condensed water flowing through the flow channel can be adjusted appropriately.

以下に、本発明にかかる一実施形態について、図面を参照して説明する。
図１には、空気調和装置の室内機１の外観が示されている。室内機１は、壁掛形とされており、上方から室内空気を吸い込み、下方から室内へと空調後の空気を吹き出す。室内機１は、図示しない室外機と接続されており、室外機にて圧縮された冷媒の供給を受け、室内機１の内部に設けられた室内熱交換器によって室内の空気を所定温度に調整する。 Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.
FIG. 1 shows the appearance of an indoor unit 1 of an air conditioner. The indoor unit 1 has a wall-hanging shape, sucks room air from above, and blows out air after air conditioning from below to the room. The indoor unit 1 is connected to an outdoor unit (not shown), receives supply of refrigerant compressed by the outdoor unit, and adjusts indoor air to a predetermined temperature by an indoor heat exchanger provided inside the indoor unit 1. To do.

図２には、室内機１の本体の内部が示されている。同図では、室内熱交換器やファンが取り外された状態が示されている。室内の壁部に設置されるベースプレート３には、室内熱交換器等にて凝縮したドレン水が導かれる流水路５が形成されている。流水路５は、ベースプレート３の左右方向（水平方向）に延在する溝部とされている。   FIG. 2 shows the inside of the main body of the indoor unit 1. In the figure, a state where the indoor heat exchanger and the fan are removed is shown. A flow channel 5 through which drain water condensed by an indoor heat exchanger or the like is led is formed in the base plate 3 installed on the indoor wall. The flowing water channel 5 is a groove extending in the left-right direction (horizontal direction) of the base plate 3.

流水路５は、室内機１の左端において下方へ向かうように形成されている。この流水路５の下端から流下するドレン水を受けるように、ベースプレート３の下方にドレンパン７が設けられている。ドレンパン７は、ドレン水を一時的に貯留して室内機１の外部へ排出する。   The flowing water channel 5 is formed so as to go downward at the left end of the indoor unit 1. A drain pan 7 is provided below the base plate 3 so as to receive drain water flowing down from the lower end of the water channel 5. The drain pan 7 temporarily stores drain water and discharges it to the outside of the indoor unit 1.

流水路５の底面は、左側が下方となるように長手方向の全体が傾斜しており、かつ、手前側（室内機前方側）が下方に幅方向の全体が傾斜している。これによりドレン水が左方でかつ手前側へと導かれるようになっている。なお、流水路５の傾斜方向はもちろん右方や奥側（室内機後方側）としても良い。   The entire bottom surface of the water flow channel 5 is inclined in the longitudinal direction so that the left side is downward, and the front side (the indoor unit front side) is inclined downward and the entire width direction is inclined. As a result, the drain water is led to the left side and the front side. In addition, it is good also as a right side or a back | inner side (indoor unit back side) as well as the inclination direction of the flowing water channel 5.

図３には、流水路５の部分拡大図が示されている。流水路５は、室内機１の手前側（同図において上方）に壁部５ｂが形成されており、この壁部５ｂに沿ってドレン水は左方から右方へと流れる。すなわち、流水路５の底面５ａは、左方から右方に向かうＤ１方向に下方へ傾斜しており、かつ、室内機１の手前側に向かうＤ２方向に下方へ傾斜している。   FIG. 3 shows a partially enlarged view of the flowing water channel 5. The flowing water channel 5 has a wall 5b formed on the front side (upward in the figure) of the indoor unit 1, and drain water flows from the left to the right along the wall 5b. That is, the bottom surface 5a of the flowing water channel 5 is inclined downward in the D1 direction from the left to the right, and is inclined downward in the D2 direction toward the near side of the indoor unit 1.

流水路５の底面には、上方に突出するリブ（突起）１１が設けられている。リブ１１は、壁部５ｂの長手方向に所定間隔をおいて複数設けられている。リブ１１は、壁部５ｂに接し、壁部５ｂの延在方向に対して直交する方向に延在している。リブ１１の延在方向の長さは、流水路５の幅よりも小さくされており、流水路５の一部を遮るようになっている。リブ１１によって、矢印で示すように、ドレン水がリブ１１を迂回するように流れる。これにより、流水路５を流れるドレン水の流速が低減される。   A rib (protrusion) 11 protruding upward is provided on the bottom surface of the water flow channel 5. A plurality of ribs 11 are provided at predetermined intervals in the longitudinal direction of the wall 5b. The rib 11 is in contact with the wall portion 5b and extends in a direction orthogonal to the extending direction of the wall portion 5b. The length of the rib 11 in the extending direction is set to be smaller than the width of the flowing water channel 5 so as to block a part of the flowing water channel 5. As indicated by the arrows, drain water flows through the ribs 11 so as to bypass the ribs 11. Thereby, the flow speed of the drain water which flows through the flowing water channel 5 is reduced.

上述の室内機１によれば、以下の作用効果を奏する。
流水路５の底面５ａに流水路５の一部を遮るリブ１１を設けることとしたので、流水路５を流れるドレン水の流速を調整することができる。これにより、底面５ａの傾斜が想定以上に大きく傾斜して室内機１が設置された場合であっても、ドレン水の流速が大きすぎてドレン水が流水路５を越えて漏出してしまうことを防止することができる。 According to the indoor unit 1 described above, the following operational effects can be obtained.
Since the rib 11 that blocks a part of the flow channel 5 is provided on the bottom surface 5 a of the flow channel 5, the flow rate of the drain water flowing through the flow channel 5 can be adjusted. As a result, even when the indoor unit 1 is installed with the inclination of the bottom surface 5a being larger than expected, the flow rate of the drain water is too large and the drain water leaks over the flow channel 5. Can be prevented.

流水路５の底面５ａを長手方向の一方向に向かって全体を傾斜させるとともに、幅方向の一方向に向かって全体を傾斜させるようにしたので、流水路５に流れ込んだドレン水は、長手方向に一方向に集められるとともに幅方向の壁部５ｂ側に集められる。したがって、底面５ａにリブ１１を設ける際に、ドレン水の流速を調整するために効果的な位置に設定することができる。   Since the entire bottom surface 5a of the flowing water channel 5 is inclined in one direction in the longitudinal direction and the entire surface is inclined in one direction in the width direction, the drain water flowing into the flowing water channel 5 is Are gathered in one direction and gathered on the wall 5b side in the width direction. Therefore, when the rib 11 is provided on the bottom surface 5a, it can be set at an effective position for adjusting the flow rate of the drain water.

壁部５ｂは、底面５ａの幅方向において最も低い位置となるのでドレン水が集まる位置となる。この壁部５ｂに接するようにリブ１１を設けることで、効果的に水の流速を調整することができる。
また、リブ１１の長さや高さを変化させることで、ドレン水の流速を調整することができる。 Since the wall part 5b becomes the lowest position in the width direction of the bottom face 5a, it becomes a position where drain water gathers. By providing the rib 11 so as to be in contact with the wall 5b, the flow rate of water can be adjusted effectively.
Moreover, the flow rate of drain water can be adjusted by changing the length and height of the rib 11.

なお、本実施形態のリブ１１の形状は、以下のように変形することができる。   In addition, the shape of the rib 11 of this embodiment can be deform | transformed as follows.

［第１変形例］
図４に示すように、壁部５ｂの延在方向に対して直交する方向に対して所定角度θだけ傾斜させてリブ１２を設置しても良い。同図に示したように水の流れ方向に沿うようにリブ１２を傾斜させて突起を設けると、ドレン水の流速の低減効果を抑えることができる。
また、図４に示した方向と反対方向に傾斜させて水の流れ方向に向かうようにリブを傾斜させると、リブによる流れ抵抗が大きくなり流速をより低減できる。 [First Modification]
As shown in FIG. 4, the ribs 12 may be installed at a predetermined angle θ with respect to a direction orthogonal to the extending direction of the wall 5 b. As shown in the figure, if the rib 12 is inclined so as to follow the water flow direction and the protrusion is provided, the effect of reducing the flow rate of the drain water can be suppressed.
Further, if the rib is inclined so as to be inclined in the direction opposite to the direction shown in FIG. 4 and directed in the direction of water flow, the flow resistance by the rib is increased and the flow velocity can be further reduced.

［第２変形例］
図５に示すように、リブ１３の中間位置に切欠１３ａを形成しても良い。
切欠１３ａをドレン水が通過する際に流速を低減することができる。この切欠１３ａの大きさを適宜変更することによってドレン水の流速を調整することができる。 [Second Modification]
As shown in FIG. 5, a notch 13 a may be formed at an intermediate position of the rib 13.
When drain water passes through the notch 13a, the flow velocity can be reduced. By appropriately changing the size of the notch 13a, the flow rate of the drain water can be adjusted.

［第３変形例］
図６に示すように、リブ１４をタイル状に並べても良い。
リブ１４をタイル状に並べることで、リブ１４間を流れるドレン水の流速を低減することができる。同図に示すように、リブ１４を千鳥状に配置することで、よりドレン水の流速の低減効果を得ることができる。
また、リブ１４間の間隔を適宜変更することによって水の流速を調整することができる。なお、リブ１４の形状は、同図に示したように平面視した場合に四角形状とされている場合に限らず、３角形や５角形以上の多角形としても良いし、円形や楕円形としても良い。 [Third Modification]
As shown in FIG. 6, the ribs 14 may be arranged in a tile shape.
By arranging the ribs 14 in a tile shape, the flow rate of drain water flowing between the ribs 14 can be reduced. As shown in the figure, by arranging the ribs 14 in a staggered manner, the drain water flow velocity can be further reduced.
Moreover, the flow rate of water can be adjusted by changing the space | interval between the ribs 14 suitably. The shape of the rib 14 is not limited to a quadrangular shape when viewed in plan as shown in the figure, and may be a triangle or a polygon that is a pentagon or more, or a circle or an ellipse. Also good.
