- the flow velocity of water can be effectively adjusted by providing a protrusion so as to be in contact with the wall.
- the protrusions may be provided in a direction perpendicular to the extending direction of the wall. Alternatively, the protrusion may be provided to extend at a predetermined angle with respect to the direction orthogonal to the extending direction of the wall. If the protrusions are inclined toward the water flow direction, the flow resistance due to the protrusions can be increased and the flow velocity can be further reduced.
- a notch is formed at an intermediate position of the protrusion.
- the flow velocity can be reduced when water passes through the notch.
- the flow rate of water can be adjusted by changing the size of this notch appropriately.
- the protrusions are arranged in a tile.

- the water flow path 5 is a groove extending in the lateral direction (horizontal direction) of the base plate 3.
- the water flow path 5 is formed to be directed 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 flow path 5. The drain pan 7 temporarily stores drain water and discharges it to the outside of the indoor unit 1.
- the bottom surface of the water flow channel 5 is entirely inclined in the longitudinal direction such that the left side is downward, and the whole in the width direction is inclined downward on the near side (the indoor unit front side). As a result, the drain water is led to the left side and the front side.
- the inclination direction of the water flow passage 5 may be the right side or the rear side (the indoor unit rear side).
- FIGS. 3A and 3B A partially enlarged view of the flowing water channel 5 is shown in FIGS. 3A and 3B.
- the water flow path 5 has a wall 5b formed on the front side (upper side 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 water flow passage 5 is inclined downward in the D1 direction from the left to the right, and downward in the D2 direction toward the front side of the indoor unit 1.

- the length in the extension direction of the rib 11 is smaller than the width of the water flow passage 5 and blocks part of the water flow passage 5.
- the rib 11 causes drain water to flow around the rib 11 as indicated by the arrow. Thereby, the flow velocity of the drain water flowing through the flowing water channel 5 is reduced.
- the following effects are achieved. Since the rib 11 is provided on the bottom surface 5 a of the water flow channel 5 to block part of the water flow channel 5, the flow velocity of drain water flowing through the water flow channel 5 can be adjusted. As a result, even if the indoor unit 1 is installed with the inclination of the bottom surface 5a inclined more than expected, the flow velocity of the drain water is too high and the drain water leaks beyond the flowing water passage 5 Can be prevented.
- the bottom surface 5a of the water flow channel 5 is entirely inclined in one longitudinal direction and the whole is inclined in one width direction, so that drain water flowing into the water flow channel 5 is in the longitudinal direction. In one direction and in the width direction wall 5b. Therefore, when providing the rib 11 in the bottom face 5a, it can set to the effective position in order to adjust the flow velocity of drain water.
- the wall portion 5b is at the lowest position in the width direction of the bottom surface 5a, and hence is a position at which drain water is collected.
- the flow velocity of water can be effectively adjusted by providing the rib 11 so as to be in contact with the wall 5b.
- the flow velocity of drain water can be adjusted by changing the length and height of the rib 11.
- the shape of the rib 11 of this embodiment can be deform
- the ribs 12 may be installed at a predetermined angle ⁇ with respect to the direction orthogonal to the extending direction of the wall 5b. As shown in the figure, when the rib 12 is inclined to provide a protrusion along the flow direction of water, the effect of reducing the flow velocity of drain water can be suppressed. In addition, when the rib is inclined in the direction opposite to the direction shown in FIGS. 4A and 4B and directed to the flow direction of water, the flow resistance by the rib increases and the flow velocity can be further reduced.
- a notch 13a may be formed at an intermediate position of the rib 13.
- the flow velocity can be reduced when drain water passes through the notch 13a.
- the flow velocity of drain water can be adjusted by appropriately changing the size of the notch 13a.
- the ribs 14 may be tiled. By arranging the ribs 14 in a tile shape, the flow velocity 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, it is possible to obtain a further reduction in the flow velocity of drain water. In addition, the flow velocity of water can be adjusted by appropriately changing the distance between the ribs 14.
- the shape of the rib 14 is not limited to a quadrilateral shape in plan view as shown in the figure, and may be a triangle or a polygon having five or more sides, or a circle or an ellipse. Also good.

Abstract
Description
すなわち、本発明の一態様に係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。
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。
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。
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。
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。
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。
図4A及び図4B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4A及び図4B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。
図5A及び図5B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。
図6A及び図6B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。
