Description

往复式压缩机
本发明涉及一用于空调、冰箱、冰柜或类似物中的带有压缩室的往复式压缩机,特别是一进气门和排气门,它们分别控制制冷工质通过进气孔流进压缩室并通过排放孔流出压缩室。
使用在冰箱上的往复式压缩机通常在高压下压缩制冷剂,然后经过冷凝、膨胀和蒸发这一循环。如图4所示,常规的往复式压缩机包括一具有进气管(未示出)和排气管的密闭腔室10、一布置在密闭腔室中用于产生能量的电动机30和一压缩部件20。电动机30包括定子31、转子32、通过加压安装在转子32上的转轴34和与转轴的较低端成一体的偏心轴33。压缩部件20还包括一安装在电动机下部、一端为开口的中空气缸体22,一锁闭气缸体22的开口端使其形成气缸内孔21作为压缩室的气缸盖23,一在压缩室21中作往复运动、用于制冷剂的进气、压缩和排气的活塞24和一将偏心轴33的偏心转动转化为线性运动的连杆25。另外,气缸盖23上有分别将制冷剂的进气和排气导入压缩室21和从中导出的进气室27和排气室26。主气门板50安装在气缸盖23和气缸体22之间,它具有进气和排气门,并分别用图5中的标号2和1表示,用于将压缩室21分别与进气室27或排气室26相连。
在这样的常规往复式压缩机中,假如由于定子31和转子32之间的相互感应使得转动轴34、继而偏心轴33开始转动,偏心轴33的偏心旋转运动经连杆25转化成线性往复运动,因此,活塞24在压缩室21中线性地往复运动,并带动制冷剂从进气室27进入压缩室21,压缩制冷剂通过排气室26排入密封闭腔室10的内部。被压缩了制冷剂最终通过排放管(未示出)进入制冷系统。
参照图5来描述这种常规往复式压缩机的进气和排气门。图5示出了被剖示的压缩部分的透视图,主气门板50布置在气缸体22和气缸盖23之间,它具有进气孔51和排气孔52,分别用于将压缩室21与进气室27和排气室26相连。进气门板54上具有与其整体成形的进气门2,该板安装在主气门板50上并朝着压缩室21的内侧,这样进气门2可打开或关闭进气孔51。另一方面,排气门1安装在主气门板50上并朝着排气室26的外侧,以便随着进气孔51的打开与关闭相交替地打开或关闭排气孔52。另外垫片57和58分别安装在主气门板50的两侧,用于防止制冷剂的泄漏。进气与排气门2和1由弹性材料制成,以使其可根据压缩室21中的压力变化打开或关闭进气和排气孔51和52。
进一步参照图6,示出了排气门1的结构,排气门1的一端安装在主气门板50上,以便完全关闭排气孔52,它的开启范围由安装在其上的限位件55所限制。安装在二者之上的是一个固定件56,用于固定排气门1和限位件55。
在这样的常规进气和排气的运行中,当活塞24如图4所示朝左端(下死点)运动时,压缩室21中的压力变得低于进气室27中的压力,进气门2朝着压缩室21的方向打开,因此将制冷剂带进压缩室。后如果压缩室21中的压力与进气室27中的压力达到平衡,进气门2弹性地回到原位,关闭进气口51。当活塞24开始经下死点向上死点方向运动时,压缩制冷剂,因此,压缩室21中的压力变得高于排气室26中的压力,排气门1打开,将压缩的制冷剂通过排气口52排出密闭腔室的内部。
这种常规进气和排气门的缺点是在进气和排气孔与进气和排气门之间通常会形成油膜,阻碍了气门的开启操作,因此比不存在油膜时需要更大的力来开启气门,所以压缩机的工作效率降低了。此外如图6所示,排气门受到限位件的压力,需附加的力使其开启。
本发明的一个目的就是提供一用于往复式压缩机上的一个进气门和一个排气门,这些气门包括一个能使气门朝着开启方向得到一弹性力的装置。
本发明的另一目的就是提供一装置用于将进气和排气门与进气和排气孔稍微分开以便去除门和孔之间形成的油膜,因此减少了开启气门所需的力和运行压缩和所需的电能。
根据本发明的一个实施例,往复式压缩机包括一密闭腔室、带有气缸盖的气缸体、气缸体内的压缩室、具有制冷剂进出的进气孔和排气孔的主气门板,所述主气门板安装在气缸体和气缸盖之间,用于控制制冷剂通过进气孔进入压缩室的进气门和用于控制制冷剂通过排气孔排出压缩室的排气门,其特征是在进气门和排气门中的至少一个上安装了弹性装置,使气门容易打开。
现在将参考附图及其举例,对本发明作详细的描述。
图1是使用本发明的进气和排气门的往复式压缩机压缩部分的剖示透视图。
图2A是本发明进气气门的底视图,为图1的"U"方向视图。
图2B是图2A的2-2剖面图。
图3A是安装在阀板上的本发明排气门的剖面图,为图1的3-3剖面图。
图3B是本发明排气门的平面图。
图3C是图3B的3C-3C剖面图。
图4是传统往复式压缩机的内部结构的剖面图。
图5是图4压缩部分的剖示透视图。
图6是安装在气门板上的传统排气门的剖面图,为图5的6-6剖面图。
在参考附图描述本发明的优选实施例之前,请注意,本发明的结构与常规结构所对应的部件使用了相同的标号。
参照图1,主气门板50安装在气缸体20和气缸头23之间,板上有进气口51和排气口52分别将压缩室21与进气室27和排气室26连接起来。进气门板54上具有的其整体成形的进气门70,该板安装在主气门板50朝着压缩室21的内侧,所以进气门70可打开或关闭进气口51。另一方面,排气门60安装在主气门板50朝着排气室26的外侧位置,因此可打开或关闭排气孔52,并使其与进气口51的打开或关闭交替进行。另外,垫片57和58分别安装在主气门板50的两侧,用于防止制冷剂的泄漏,进气和排气门70和60上有弹性条75和69,以下将要详细叙述的本发明有助于气门的打开。
参照图2A,进气门70与进气门板54整体成形,该板54与气门板50具有相同外形。例如进气门板54在与进气口51相对应的区域上切割形成进气门,气门的端部为与进气口51接触的气门座71。与进气门板54相连的进气门70的根部位于与气门座71相对的另一端,其上有有助于进气门打开的弹性条75,弹性条75上设有一辅助切条72,它是通过切割其根部与进气门70的根部相连接的弹性条75形成的。如图2B所示,辅助切条72弯向压缩室21形成弹性区73,使辅助切条72的自由端72F指向压缩室21,因此,弹性条75具有将进气门轻微地推向其开启方向的弹性力。
参照图3A,排气门60安装在主气门板50朝着排气室26的外侧凹槽59中,在与排气孔52相对应的区域上有气门座61。如图3A所示,位于气门座61相对端的排气门60的根部65固定地贴附在气门板50上。限位件55安装在排气门60的上部用于限制排气门的开启范围。排气门60的根部由限位件55的一端固定,而限位件又由固定件56固定。
排气门上有弹性条69,该条向排气门施加的弹性力,使其容易打开。弹性条69与使用在进气门70上的弹性条75具有相同结构,因此就不再赘述。弹性条69的弯曲弹性区63接触主气门板50的表面,轻微地将排气门60推向排气室,因此排气门60的气门座61与排气孔52稍微分开,只有在制冷剂进入压缩室时例外。
在工作中,当活塞24朝下死点运动,压缩室21中的压力降低至低于进气室27中的压力时,进气门在压差的作用下开启。与此同时,排气门60朝压缩室21方向运动,克服弹性条的弹性力关闭排气孔52。另一方面,当活塞24朝上死点运动并压缩制冷剂时,压缩室中的压力使进气门70关闭进气孔51,同时,排气门60被压缩室中的压力推向排气室26,打开排气孔52。因此被压缩了的制冷剂通过排气室26进入密闭腔室10的内部,然后通过排气管11进入制冷系统。当进气门70和排气门60开启时,弹性条75和69用于促进其打开,即:使进气门朝压缩室21方向受力,使排气门朝排气室26方向受力。
如上所述,由本发明的结构所固有的弹性力可将进气和排气门稍微推向其开启方向,因此压缩机节约了开启气门所必需的能量,改善了工作效率。概括地说,本发明的气门的工作情况为:由压缩室和进气室间的压差操纵的进气门受到弹性条的指向压缩室的弹性力,因此,大大减少了用于开启进气门所需的力。另外,排气门与排气孔因有一定间隔而稍稍分开,以防止制冷剂中的油在排气门和排气孔之间形成油膜,排气门也受到弹性条的指向排气室的弹性力,因此减少了开启气门所需的力,其结果是压缩机节约了电能,改善了工作效率。
