需要说明的是, 第一管道 2和第二管道 3可均由多条首尾相连的子管道构造成, 第 一管道 2和第二管道 3还可分别由一条管道构造成。
第一换热器 4设在第一腔室 13内。 需要说明的是, 第一腔室 13内还设有第一风机 11, 在第一风机 11的作用下, 室内空气可从室内环境进入到第一腔室 13内与第一换热 器 4进行换热, 换热后的空气送回到室内环境内, 从而实现对室内环境进行制冷 /制热 的目的。
第二换热器 5设在第二腔室 14内, 第二换热器 5与第一换热器 4相连, 需要说明 的是, 第二腔室 14与室外环境连通, 且第二腔室 14内还设有第二风机 12, 在第二风 机 12的作用下, 室外空气进入到第二腔室 14内以与第二换热器 5进行换热, 换热后的 室外空气送回到室外环境中。
压縮机 6可设在第一腔室 13或第二腔室 14内, 在图 1和图 2的示例中, 压縮机 6 设在第二腔室 14内,压縮机 6分别与第一换热器 4和第二换热器 5相连。当空调器 100 为单冷机时, 从压縮机 6排出的冷媒进入到第二换热器 5内, 从第二换热器 5排出的冷 媒进入到第一换热器 4内以与第一腔室 13内的空气进行换热以冷却第一腔室 13内的空 气, 第一腔室 13内的冷空气排入到室内环境内以实现对室内环境进行制冷的目的, 从 第一换热器 4排出的冷媒回到压縮机 6内, 以完成一次制冷循环。
当空调器 100为冷暖机时, 此时空调器 100还包括四通阀以实现制冷模式和制热模 式之间的切换, 当空调器 100处于制冷模式时, 从压縮机 6排出的冷媒进入到第二换热 器 5内, 从第二换热器 5排出的冷媒进入到第一换热器 4内以与第一腔室 13内的空气 进行换热以冷却第一腔室 13内的空气,第一腔室 13内的冷空气排入到室内环境内以实 现对室内环境进行制冷的目的, 从第一换热器 4排出的冷媒回到压縮机 6内, 以完成一 次制冷循环。 当空调器 100处于制热模式时, 从压縮机 6排出的冷媒进入到第一换热器 4内以与第一腔室 13内的空气进行换热以加热第一腔室 13 内的空气, 第一腔室 13内 的热空气排入到室内环境内以实现对室内环境进行制热的目的,从第一换热器 4排出的 冷媒进入到第二换热器 5内, 从第二换热器 5排出的冷媒回到压縮机 6内, 以完成一次 制热循环。
检测装置用于检测空调器 100是否出现冷媒泄漏, 其中, 检测装置可为任何装置, 只要可用于检测空调器 100内例如第一腔室 13、 第二腔室 14、 第一管道 2等位置是否 出现冷媒泄漏即可。
控制装置 82与检测装置和第一控制阀 80电连接, 在图 1和图 2的示例中, 控制装 置 82设在室内环境中,控制装置 82根据检测装置的检测结果控制第一管道 2的第一控 制阀 80的打开或关闭。 具体而言, 当检测装置检测到空调器 100内出现冷媒泄漏时, 控制装置 82控制第一控制阀 80关闭以关闭第一腔室 13的出风口, 从而避免冷媒进入 到室内环境中, 当检测装置检测到空调器 100内没有出现冷媒泄漏时, 控制装置 82控 制第一控制阀 80打开以打开第一腔室 13的出风口, 换言之, 控制装置 82控制第一控 制阀 80的打开或关闭实质是控制第一腔室 13的出风口的打开或关闭。
根据本发明实施例的空调器 100, 通过将第一换热器 4和第二换热器 5均设在室外 机壳体 1内, 当检测装置检测到冷媒泄漏时, 控制装置 82控制第一控制阀 80关闭以关 闭第一腔室 13的出风口, 从而可最大程度地避免泄漏的冷媒进入到室内环境内, 同时 通过将第一换热器 4设在室外机壳体 1内, 从而彻底地解决了室内侧的噪音污染, 提高 空调器 100的使用舒适性。
在本发明的进一步实施例中, 第二管道 3内设有第二控制阀 81, 控制装置 82根据 检测装置的检测结果控制第二管道 3的第二控制阀 81打开或关闭。 即当检测装置检测 到冷媒泄漏时, 控制装置 82控制第二控制阀 81关闭以关闭第一腔室 13的进风口, 从 而可进一步避免冷媒泄漏到室内环境中。换言之, 控制装置控制第二管道 3的打开或关 闭实质是控制第一腔室 13的进风口的打开或关闭。 在本发明的进一步实施例中, 第一腔室 13的侧壁、 第一管道 2和 /或第二管道 3上 设有通风口, 该通风口可打开和关闭, 控制装置 82连接至通风口以根据检测装置的检 测结果打开或关闭通风口, 当检测到冷媒泄漏时, 控制装置 82控制通风口打开, 使得 第一腔室 13、 第一管道 2和 /或第二管道 3内与室外环境连通以便于冷媒扩散到室外环 境中, 当未检测到冷媒泄漏时, 控制装置 82控制通风口关闭, 第一腔室 13、 第一管道 2和 /或第二管道 3内与室外环境隔离, 以保证空调器 100可正常工作。其中, 在本发明 的优选实施例中, 控制装置 82同步控制第一管道 2和第二管道 3关闭、 通风口打开, 控制装置 82同步控制第一管道 2和第二管道 3打开、 通风口关闭。 从而可对室内侧进 行换气, 在日常使用中, 用户可根据需要选择是否进行换气, 保证室内环境在日常使用 中有新鲜空气进入。
需要说明的是, 通风口的位置可根据实际情况具体设定, 以保证冷媒可快速地扩散 且可实现日常使用中的换气作用即可。
更进一步地, 控制装置 82还与第一风机 11和第二风机 12相连以控制第一风机 11 和第二风机 12的运行状态, 例如当空调器 100处于停机状态时, 当检测装置检测到空 调器 100内出现冷媒泄漏时, 此时控制装置 82控制第一风机 11和第二风机 12开启、 通风口开启、 第一管道 2和第二管道 3关闭, 以加快冷媒扩散到室外环境中。 当空调器 100处于运行状态时, 当检测装置检测到空调器 100内出现冷媒泄漏时, 此时控制装置 82加大第一风机 11和第二风机 12的运行功率、通风口开启、第一管道 2和第二管道 3 关闭, 以加快冷媒扩散到室外环境中。
在本发明的进一步实施例中, 空调器 100还可包括报警装置, 当检测装置检测到空 调器 100内出现冷媒泄漏时, 控制装置 82控制报警装置报警例如发出声光警告, 以提 醒用户空调器出现冷媒泄漏。
根据本发明的一些实施例, 检测装置包括第一检测单元 72, 第一检测单元 72设在 第一腔室 13内用于检测第一腔室 13内是否出现冷媒泄漏。从而可及时地检测到空调器 100是否出现冷媒泄漏。

进一步地, 如图 1和图 2所示, 控制装置 82还可根据检测装置的第一检测单元 72 的检测结果控制压縮机 6打开或关闭。从而在检测到冷媒泄漏时控制压縮机 6关闭, 在 源头上停止冷媒泄漏, 进一步提高了空调器 100的使用安全性。 具体地, 如图 1和图 2所示, 第一控制阀 80包括: 第一旋转挡片 801和第一驱动 电机, 第一旋转挡片 801 可转动地设在第一管道 2 内。 第一驱动电机与第一旋转挡片 801相连以驱动第一旋转挡片 801旋转以打开或关闭第一管道 2, 具体而言, 第一旋转 挡片 801处于常打开状态, 此时第一旋转挡片 801与空气流动方向平行, 当检测到冷媒 泄漏时, 第一驱动电机驱动第一旋转挡片 801旋转 90度, 使得第一旋转挡片 801与空 气流动方向呈现垂直状态, 达到关闭第一管道 2的目的, 从而使得第一控制阀 80的结 构简单。
具体地, 如图 1和图 2所示, 第二控制阀 81包括: 第二旋转挡片 811和第二驱动 电机, 第二旋转挡片 811 可转动地设在第二管道 3 内。 第二驱动电机与第二旋转挡片 811相连以驱动第二旋转挡片 811旋转以打开或关闭第二管道 3。 具体而言, 第二旋转 挡片 811处于常打开状态, 此时第二旋转挡片 811与空气流动方向平行, 当检测到冷媒 泄漏时, 第二驱动电机驱动第二旋转挡片 811旋转 90度, 使得第二旋转挡片 811与空 气流动方向呈现垂直状态, 达到关闭第二管道 3的目的, 从而使得第二控制阀 81的结 构简单。

如图 1和图 2所示, 第一子管道 20与第一腔室 13连通, 第一 子管道 20和风向 切换装置 9相连, 第二子管道 21与风向切换装置 9相连, 第二子管道 21与室内环境连 通, 第三子管道 30与第一腔室 13连通, 第三子管道 30和风向切换装置 9相连, 第四 子管道 31与风向切换装置 9相连, 第四子管道 31和室内环境连通, 具体地, 第一控制 阀 80设在第一子管道 20上, 第二控制阀 81设在第三子管道 30上。
具体而言, 在空调器 100处于制热模式时, 第一子管道 20和第四子管道 31导通、 第二子管道 21和第三子管道 30导通, 在第一风机 11的作用下, 室内空气经过第二子 管道 21和第三子管道 30进入到第一腔室 13内,进入到第一腔室 13内的室内空气与第 一换热器 4进行热交换以升高温度, 从而成为热空气, 热空气经过第一子管道 20和第 四子管道 31进入到室内环境内,此时由于热空气从相对较低的位置吹入到室内环境内, 从而可实现快速制热的目的。 当空调器 100处于制冷模式时, 第一子管道 20和第二子管道 21导通, 第三子管道 30和第四子管道 31导通, 在第一风机 11的作用下, 室内空气经过第四子管道 31和第 三子管道 30进入到第一腔室 13内, 进入到第一腔室 13内的室内空气与第一换热器 4 进行换热以降低温度, 从而成为冷空气, 冷空气经过第一子管道 20 和第二子管道 21 进入到室内环境中, 此时由于冷空气从相对较高的位置吹入到室内环境内, 从而可实现 快速制冷的目的。
根据本发明实施例的空调器 100, 通过设有风向切换装置 9, 控制装置控制风向切 换装置 9切换导通状态以控制第四子管道 31和第三子管道 30中的一个形成为出风通 道, 从而可实现快速制冷和快速制热的目的。
