As shown in FIG. According to this configuration, the slide member 4 and the cover member 2 are supported from below at two points, the first support member 6 and the second support member 7 . Therefore, it is possible to more effectively prevent the slide member 4 and the cover member 2 from sagging under their own weight.
- the slide member 4 is formed with a long hole 4b extending along the sliding direction, and the second support member 7 is inserted through the long hole 4b. According to this configuration, the slide member 4 can be slid so that the long hole 4b and the second support member 7 slide.
- the long hole 4b has a pair of side surfaces extending in the sliding direction, and at least one of the pair of side surfaces has an orthogonal direction (X A projection 4f is formed on the shaft), and the projection 4f rides over the second support member 7 in the sliding direction when the slide member 4 slides between the restricting position and the releasing position. According to this configuration, the protrusion 4f can prevent the slide member 4 from unexpectedly moving between the restricted position and the released position.
- the distance between the pair of side surfaces is W2
- the width of the long hole 4b at the portion where the projection 4f is formed is Wt2
- Dc2 ⁇ W2 the second support member 7 can be easily slid with respect to the elongated hole 4b except for the portion where the projection 4f is formed.
- Wt2 ⁇ Dc2 the projection 4f can effectively prevent the slide member 4 from moving unexpectedly with respect to the second support member 7. As shown in FIG.
- the cover member 2 has a guide groove 2f extending along the slide direction
- the slide member 4 has a guide claw 4h that is engaged with the guide groove 2f.
- the slide member 4 also moves integrally with the cover member 2 when the cover member 2 is moved between the cover position and the open position. Operability is improved by configuring the cover member 2 and the slide member 4 so as not to be separated from each other.
- the slide member 4 can be slid so that the guide claw 4h slides with respect to the guide groove 2f.
- the slide member 4 is formed with a first blind 4i that covers at least a portion of the first support member 6 from below when the slide member 4 is in the restricted position. According to this configuration, it is possible to prevent the operator from erroneously operating the first support member 6 with a tool.
- the fixing member 3 is omitted and the first supporting member 6 and the second supporting member 7 are directly fixed to the housing 8 may be adopted. More specifically, the screw portions 6 c and 7 c of the first support member 6 and the second support member 7 may be screwed directly to the housing 8 . Also, the first support member 6 and the second support member 7 may not be shoulder bolts. For example, the first support member 6 and the second support member 7 can be insert-molded into the housing 8 .

Abstract
Description
図1は本実施の形態に係る空気調和機Aの構成例を表す図である。空気調和機Aは、室内機100、室外機200、ガス冷媒配管300、および液冷媒配管400を備えている。ガス冷媒配管300および液冷媒配管400はそれぞれ、室内機100と室外機200とを接続している。室外機200は、圧縮機210、四方弁220、室外熱交換器230、膨張弁240を有している。
以上のように空気調和機Aを構成し、四方弁220により冷媒の流れを切り換えることで、暖房運転及び冷房運転を実現することができる。
第2支持部材7のヘッド7aの外径Da2は、スライド部材4の長孔4bの幅W2よりも大きく、またカバー部材2の第2挿通孔2dの内径Db2よりも大きい。つまり、Da2>W2かつDa2>Db2を満たす。
また、第1支持部材6および第2支持部材7はショルダーボルトでなくてもよい。例えば、第1支持部材6および第2支持部材7を筐体8にインサート成形することも可能である。
