Description

电控盒
技术领域
　　　本发明涉及电控盒，具体涉及一种用于使用可燃制冷剂的空调器的电控盒。　
背景技术
　　　目前空调器使用的冷煤主要有R22、R410、R410A等，这些冷媒对臭氧层有破坏作用、并且存在温室效应。随着国际社会对日益严峻的臭氧层破坏和温室效应的关注，迫切需要使用环保、节能且低成本的新型制冷剂。因此需要寻找ODP（臭氧层破坏潜值）为零，GWP（温室效应潜值）较小的冷煤。
　　　目前能满足此要求的冷煤有R32、R290、R161等，然而这些环保型冷煤存在“易燃易爆”的缺点，当使用可燃性制冷剂的空调器发生制冷剂泄露时，可燃制冷剂会渗入电控盒里面，在电控盒里面的制冷剂达到可燃浓度，此时若电控盒里面的电控板产生电火花，就有可能引起燃烧甚至爆炸。　　　
发明内容
　　　本发明的目的在于提供一种能有效阻挡可燃制冷剂渗入的电控盒。
　　　为了实现发明目的，本发明提供一种电控盒，包括电控盒体以及盖设于电控盒体上的电控盒盖，该电控盒体具有基板，该基板的边沿垂直延伸有多个盒体侧壁，该电控盒盖具有盒盖，该盒盖的边沿垂直延伸有多个盒盖侧壁。一盒体侧壁向外凸伸有盒体凸台，该盒体侧壁和盒体凸台上开设有盒体出线槽，该盒体出线槽的槽壁上凸设有至少两盒体凸肋；另外的盒体侧壁具有位于不同平面的盒体接合面。一盒盖侧壁向外凸伸有盒盖凸台，该盒盖侧壁和盒盖凸台上开设有与盒体出线槽接合的盒盖出线槽，该盒盖出线槽的槽壁上凸设与盒体凸肋配合的至少两盒盖凸肋，另外的盒盖侧壁具有位于不同平面的盒盖接合面。所述盒体凸台在相应盒体出线槽的两侧凸伸出连接相应盒体侧壁的嵌合台，所述盒盖凸台在相应盒盖出线槽的两侧开设有嵌合槽，所述盒盖凸台与所述盒体凸台接合，且所述嵌合台伸入嵌合槽内，所述盒体侧壁与盒盖侧壁卡设在一起并使相应的盒体接合面与相应的盒盖接合面接合。
　　　优选地，所述盒体出线槽为至少两个，相应的所述盒盖出线槽也为至少两个。
　　　优选地，所述嵌合台的长度不小于两相邻的盒体凸肋之间的距离。
　　　优选地，所述凸设有盒盖凸台的盒盖侧壁和所述嵌合槽的一槽壁之间形成有连通相应的盒盖出线槽和相应的嵌合槽的连通槽，所述凸设有盒体凸台的盒体侧壁同时伸入相应的连通槽和相应的嵌合槽内。
　　　优选地，所述相应的盒体接合面与相应的盒盖接合面之间设置有密封垫或涂设有密封胶层。
　　　优选地，所述盒体侧壁形成有至少两个相互平行且高度不同的盒体凸臂，盒体凸臂之间形成盒体凹槽，盒体凸臂的顶壁以及盒体凹槽的底壁形成所述盒体接合面；所述盒盖侧壁具有至少两高度不同的盒盖凸臂，盒盖凸臂的顶壁形成所述盒盖接合面，且相应的盒盖凸臂伸入盒体凹槽内。

具体实施方式
　　　应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
　　　本发明提供一种电控盒，请参阅图1和图2，其揭示了本发明电控盒的一具体实施例，在本实施例中，电控盒包括电控盒体10、盖设于电控盒体10上的电控盒盖20以及设置在电控盒体10和电控盒盖20之间的电控板30。
　　　请参阅图3和图4，电控盒体10具有一方形的基板110，基板110的四个边沿垂直延伸有盒体侧壁120，且该基板110还向上垂直延伸有多个固定柱130。一盒体侧壁120的中部向外凸伸有盒体凸台140，该盒体侧壁120和盒体凸台140上开设有多个盒体出线槽141。盒体出线槽141的槽壁上凸设有三个盒体凸肋142。盒体凸台140在相邻的盒体出线槽141之间凸伸出连接该盒体侧壁120的嵌合台143，且嵌合台143的高度低于该盒体侧壁120的高度，嵌合台143的长度（亦即盒体出线槽141的延伸方向）不小于两相邻的盒体凸肋142之间的距离。
　　　凸设有盒体凸台140的盒体侧壁120的两端和其它盒体侧壁120均形成有两个相互平行且高度不同的第一盒体凸臂121和第二盒体凸臂122，第一盒体凸臂121和第二盒体凸臂122之间形成盒体凹槽123，从而第一盒体凸臂121和第二盒体凸臂122的顶壁以及盒体凹槽123的底壁分别形成第一盒体接合面124、第二盒体接合面125和第三盒体接合面126，该第一盒体接合面124、第二盒体接合面125和第三盒体接合面126均位于不同的平面上。
　　　请参阅图5和图6，电控盒盖20具有方形的盒盖210，盒盖210的四个边沿垂直延伸有盒盖侧壁220，其中一盒盖侧壁220的中部向外凸伸出一盒盖凸台230，该盒盖侧壁220和盒盖凸台230上开设有多个盒盖出线槽231。盒盖出线槽231的槽壁上凸设有三个盒盖凸肋232。盒盖凸台230在相邻的盒盖出线槽231之间开设有嵌合槽233，且相应的盒盖侧壁220和嵌合槽233的一槽壁之间形成有有连通盒盖出线槽231和嵌合槽233的连通槽234。
　　　凸设有盒盖凸台230的盒盖侧壁220的两端和其它盒盖侧壁220具有第一盒盖凸臂221和第二盒盖凸臂222，且第一盒盖凸臂221和第二盒盖凸臂222的高度不同，从而在第一盒盖凸臂221的顶壁形成第一盒盖接合面223、在第二盒盖凸臂222的顶壁形成第二盒盖接合面224，而在盒盖210之临近盒盖侧壁220处形成第三盒盖接合面211，第三盒盖接合面211、第一盒盖接合面223和第二盒盖接合面224均位于不同的平面上。
　　　所述盒盖210的一部分凹陷形成一方形的凸出腔240，该凸出腔240的腔壁上凸设有上下延伸的肋条241。
　　　请参阅图2，电控板30具有电路板310、设置于电路板上的电子组件320以及与电路板310或电子组件320连接的连接线330，连接线330上套设有密封橡胶套340。
　　　请参阅图2至图8，在组装该电控盒时，将电控板30的电路板310置于电控盒体10的基板110上，将密封橡胶套340置于盒体出线槽141内，并使电控盒体10的固定柱130穿过电路板310；然后将电控盒盖20扣设在电控盒体10上，使电控盒盖20的第一盒盖凸臂221卡入电控盒体10的盒体凹槽123内，从而使第二盒盖凸臂222与第二盒体凸臂122配合，使盒盖210与第一盒体凸臂121配合，亦即使第三盒盖接合面211与第一盒体接合面124配合、使第一盒盖接合面223与第三盒体接合面126配合以及使第二盒盖接合面224与第二盒体接合面125配合，为了增加密封性，可在第三盒盖接合面211与第一盒体接合面124之间、在第一盒盖接合面223与第三盒体接合面126之间以及在第二盒盖接合面224与第二盒体接合面125之间设置密封垫或涂设密封胶层；使电控盒体10的嵌合台143伸入电控盒盖20的嵌合槽233内，使盒体凸台140与盒盖凸台230配合，并使用电控盒体10之设有盒体凸台140的盒体侧壁120同时伸入电控盒盖20的连通槽234和嵌合槽233内；此外，在将电控盒盖20扣设在电控盒体10上时，凸出腔240的肋条241抵接电控板30以导引电控盒盖20顺利的扣设在电控盒体10上；在电控盒盖20扣设在电控盒体10上后，盒盖出线槽231和盒体出线槽141配合，使盒盖凸肋232和盒体凸肋142挤压密封橡胶套340。
　　　由于本发明电控盒之电控盒体10的盒体侧壁120具有高度不同的第一盒体凸臂121和第二盒体凸臂122，电控盒之电控盒盖20的盒盖侧壁220具有高度不同的第一盒盖凸臂221和第二盒盖凸臂222，从而使第三盒盖接合面211与第一盒体接合面124的结合处、第一盒盖接合面223与第三盒体接合面126的结合处以及第二盒盖接合面224与第二盒体接合面125的结合处分别位于不同的平面上，因此可燃冷媒泄露时需要经过多次拐弯后才能进入电控盒内，这增大了冷媒从电控盒的相应三个侧面方向进入电控盒内的路径；而且，由于本发明电控盒通过嵌合台143与嵌合槽233的卡合、通过盒体凸台140与盒盖凸台230配合、通过电控盒体10之设有盒体凸台140的盒体侧壁120与电控盒盖20的连通槽234的卡合、以及通过盒盖凸肋232和盒体凸肋142的挤压密封橡胶套340，这可以增加冷媒从凸设有盒体凸台140和盒盖凸台230的一侧面方向进入电控盒内的路径；因此本发明电控盒有效的控制可燃冷媒渗入的速度和渗入量，进而使电控盒内可燃冷媒始终保持在安全的浓度以下，故而有效避免电控板30产生电火花而引起的可燃冷媒燃烧甚至爆炸。
　　　此外，通过电控盒体10之设有盒体凸台140的盒体侧壁120同时伸入电控盒盖20的连通槽234和嵌合槽233内的设计，这可以进一步增加冷媒从凸设有盒体凸台140和盒盖凸台230的一侧面方向进入电控盒内的路径，而且通过将嵌合台143的长度设计为不小于两相邻的盒体凸肋142之间的距离，这可以增加冷媒从盒体出线槽141和盒盖出线槽231两侧进入盒体出线槽141和盒盖出线槽231内的路径，因此可进一步控制可燃冷媒渗入的速度和渗入量，因此可进一步控制可燃冷媒渗入的速度和渗入量。
　　　以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
