Description

分体式房间空调器室外机
技术领域
本实用新型属于分体式房间空调器领域， 尤其涉及一种分体式房间空调器室外机。 背景技术
由于氟利昂类（如现在大量使用的 R22 )制冷剂对大气臭氧屋有破坏作用且具有较高 的温室效应， 属于需要被替代的制冷剂， 而 R600a (异丁烷）、 R290 (丙烷）等一些自然 界中存在的天然化合物， 既不会破坏大气臭氧层， 叉不导致全球变暖， 属于环境完全友好 型制冷剂。 这些制冷剂正被开始研究用于制冷系统中， 例如 R600a被认为是在制冷温度较 低场合（如电水箱 )应用的制冷剂， 而 R290则被考虑用于空调系统用于替代目前大量使 用的 R22制冷剂。
由于氟利昂类制冷剂或多或少对环境有破坏作用， R290等一些自然界中存在的天然化 合物开始被考虑用做现在大量使用但临近淘汰的制冷剂 R22的替代物。但由于其可燃可爆 的物理特性， 对空调器的安全性提出了更高的要求。
室外机供电是通过如图 1、 2示意的接线板 20端子 21与室内机电源线 30连接， 在空 调器启动瞬间可能会发生打火； 空调器室内机中最容易发生泄露的地方在冷凝器焊接处， 若发生泄露， 如果冷凝器中可燃可爆制冷剂如 R290、 R32等泄漏在压缩机腔 60 , 易发生 安全事故。
由上可知， 使用 R290的空调系统需避免制冷剂进入电器部件周围积聚， 而冷凝器和 压缩机管道焊接处为制冷剂最易泄露的地方， 因此要考虑一种方法能阻隔冷凝器和压缩机 管道焊接处与电器部件， 这样在制冷剂从焊接点泄露时， 不能直接接触电器部件。 发明内容
本实用新型的目的在于提供一种分体式房间空调器室外机， 冷凝器和压缩机管道焊接 处与电器部件之间能有效地被相互隔离， 一旦制冷剂从焊接点泄露时， 不会直接接触电器 部件而引发安全隐患； 即避免了室外机强电端子产生火花 I起安全事故。

如图 1、 2, 所述分体式房间空调器为分体挂壁式房间空调器， 所述换热部件包括有冷 凝器 80和与冷凝器 80通过循环管道连接的压缩机。
所述机体包括有底盘 90、 左侧板、 右侧板 40、 顶盖和面板 50, 所述底盘 90、 左侧板 > 右侧板 40、 顶盖和面板 50包围形成第一腔体； 所述底盘 90上设置有隔板 70, 将第一腔 体分隔成为压缩机腔 60和冷凝器腔； 冷凝器和压缩机均设置在第一腔体中。
所述第二腔体为安装在所述右侧板 40内侧的一个盒体 10。
盒体 10可以为钣金件或注塑件。
所述分体式房间空调器室外机结构大致为： 底盘 90上装有冷凝器 80、 隔板 70、 右侧 板 40、 面板 50、 左侧板和顶盖（图中未示出）， 底盘 90、 隔板 70、 右側板 40、 面板 50构 成一压缩机腔 60, 冷凝器 80上焊有许多弯头 81， 弯头 81位于压缩机腔 60处， 制冷剂易 从焊接处泄漏， 在压缩机腔 60处聚集， 当空调器启动瞬间， 电流很大， 易在接线板强电 端子 21处易产生火花， 引起安全事故。
