空调机组、压缩机及其壳体结构
相关申请
本申请要求2017年06月06日申请的，申请号为201710418138.7，名称为“空调机组、压缩机及其壳体结构”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及空调设备技术领域，特别是涉及一种空调机组、压缩机及其壳体结构。
背景技术
压缩机的工作原理是由电机转动带动转子转动压缩冷媒，但其动力系统势必会带来噪音震动，因此减震降噪便成为各产品开发中需要考量的必要因素。通常，压缩机在设计中会考虑震源周围的结构的强度、变形量大小及均匀性等问题，会将支撑筋结构均布在震源周围的结构上，这样一来震动的传递路径上，部分支撑筋会直接将震动传到支脚上，此时压缩机的震动值往往会偏大，进而压缩机运行时会将震动传递给整机，增加整机的震动值，影响整机的运行可靠性。
发明内容
基于此，有必要针对目前支撑筋直接将震动传递到支脚上导致的压缩机震动值偏大的问题，提供一种能够延长振动的传递路径、减少振动输出的壳体结构，同时还提供一种含有上述壳体结构的压缩机，以及含有上述压缩机的空调机组。
上述目的通过下述技术方案实现：
一种壳体结构，包括：
外壳，所述外壳的底部设置有多个支脚；
支撑部件，设置于所述外壳中，所述支撑部件能够支撑压缩机的电机及转子；及
连接部件，所述连接部件的一端与所述支撑部件连接，所述连接部件的另一端与所述外壳连接，且所述连接部件与所述外壳的连接处远离所述支脚。
在其中一个实施例中，所述连接部件与所述外壳的连接处位于所述支脚的上方。
在其中一个实施例中，所述连接部件与所述外壳的连接处在竖直面的投影高于所述外壳的中心在所述竖直面的投影。
在其中一个实施例中，所述连接部件的形状为直线型、曲线形或者直线型与曲线形的拼接组合。
在其中一个实施例中，所述连接部件包括环绕部及设置在所述环绕部两端的连接部，所述连接部件的两端分别通过连接部连接到所述支撑部件上及所述外壳上，所述环绕部至少部分环绕所述支撑部件。
在其中一个实施例中，所述连接部件的数量为多个，多个所述连接部件与所述外壳的连接处分别沿所述外壳的周向方向分布，且各所述连接部件之间非接触。
在其中一个实施例中，多个所述连接部件呈放射状设置，且多个所述连接部件沿外壳的周向方向均匀分布。
在其中一个实施例中，离所述支脚最近的所述连接部件和所述外壳的连接处与所述支脚和所述外壳的连接处的圆心角的范围为50°～150°。
一种压缩机，包括电机、转子及如上述任一技术特征所述的壳体结构；
所述电机的输出端与所述转子连接，且所述电机与所述转子均安装于所述壳体结构的外壳中，所述壳体结构的所述支撑部件支撑所述电机与所述转子的连接处。
一种空调机组，包括如上述技术特征所述的压缩机。
采用上述技术方案后，本申请的有益效果为：
本申请的空调机组、压缩机及其壳体结构，支撑部件通过连接部件与外壳连接，以将支撑部件上的震动通过外壳传递到支脚上，而且，由于连接部件与外壳的连接处远离支脚，以增加支撑部件到支脚的传递距离，这样震动在外壳上需要经过一段传递路径之后才能到达支脚上，有效的解决目前支撑筋直接将震动传递到支脚上导致的压缩机震动值偏大的问题，延长震动在外壳上的传递路径，从而减少压缩机最终的震动输出，降低运动过程中传递给空调机组整机的震动值，最终减小空调机组整机的震动值，保证整机运行的可靠性。

为了使本申请的目的、技术方案及优点更加清楚明白，以下通过实施例，并结合附图，对本申请的空调机组、压缩机及其外壳组件进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
参见图1，图1为本申请一实施例的壳体结构100的结构示意图。本申请提供了一种壳体结构100，该壳体结构100用于压缩机中，以降低压缩机运行时的震动；在本申请的实施例中，压缩机是指螺杆压缩机。当然，本申请的壳体结构100还可作为其他需要减震设备的外壳。本申请的壳体结构100能够有效的解决目前支撑筋直接将震动传递到支脚111上导致的压缩机震动值偏大的问题，增加震动的传递路径，从而减少压缩机最终的震动输出，降低运动过程中传递给空调机组整机的震动值，最终减小空调机组整机的震动值，保证整机运行的可靠性。
在本申请中，壳体结构100包括外壳110、支撑部件120及连接部件130。外壳110是用来起收容作用的，压缩机的各个零部件均设置于外壳110中，以起到保证压缩机正常运行，同时还能起到防护、降噪等作用。支撑部件120是用来支撑压缩机的电机和转子的，压缩机的电机的输出端与转子连接，电机在驱动转子转动时，电机与转子均会产生震动，通过支撑部件120支撑电机与转子后，能够降低压缩机运行时电机与转子的震动，保证压缩机的使用性能，提高压缩机运行的可靠性。进一步地，支撑部件120为截面形状封闭的结构，这样能够保证支撑部件120支撑可靠。较佳地，支撑部件120为支撑环。连接部件130是用来连接外壳110与支撑部件120的，以保证支撑部件120可靠的固定在外壳110中；而且，连接部件130能够将支撑部件120上的震动传递到外壳110上，再通过外壳110将震动传递到支脚111上，以降低支撑部件120的震动，保证电机与转子平稳运行。
外壳110上设置有支架，压缩机通过外壳110上的支脚111安装在零件安装部200的安装表面上，以保证外壳110的位置固定，进而使得外壳110上的震动通过支脚111传递到零件安装部200上。同时，连接部件130与外壳110的连接处远离支脚111，也就是说，连接部件130与外壳110的连接处和支脚111与外壳110的连接处之间沿外壳110的周向方向存在一定的距离，支撑部件120上的震动通过连接部件130传递到外壳110上后，沿外壳110运动一定距离后，才能传递到支脚111上。这样，由于震动会在传递的过程中衰减，通过尽量 延长震动通过连接部件130传递到外壳110上，再到最终的支脚111上的传递路径，增加震动实际的传递路径，加强震动在外壳110上的衰减，从而降低压缩机运行时的震动值，进而降低压缩机最终传递给零件安装部200的震动值，以降低空调机组整机的震动，提高运行可靠性。
本申请的压缩机的壳体结构100通过改善外壳110上的震动传递路径，延长震动的传递路径，使得震动通过连接部件130先传递到外壳110上，再通过外壳110传递到支脚111上，外壳110与支脚111之间的传递路径能够起到衰减震动的作用，以降低传递到支脚111上的震动值，进而降低压缩机在运行过程中传递给零件支撑部的震动值，以减小空调机组的整机震动值，保证压缩机运行稳定可靠。
作为一种可实施方式，连接部件130与外壳110的连接处位于支脚111的上方。通常，压缩机的外壳110的支脚111是设置在外壳110的底部的，以起到固定支撑的作用，同时，还能便于外壳110的固定，方便压缩机的固定。由于连接部件130与外壳110的连接处位于支脚111的上方，这样能够保证连接部件130与外壳110的连接处和支脚111与外壳110的连接处在外壳110周向方向上存在一定的传递路径，达到衰减外壳110上震动的目的，从而降低传递到支脚111上的震动值，进而降低压缩机在运行过程中传递给零件支撑部的震动值，保证压缩机运行稳定可靠。当然，在本申请的其他实施方式中，连接部件130与外壳110的连接处也可位于支脚111的下方，此时需要保证连接部件130与外壳110的连接处与支脚111之间存在一定的传递路径，这样也能够实现连接部件130上的震动通过外壳110衰减后再传递到支脚111上。
进一步地，连接部件130与外壳110的连接处在竖直面的投影高于外壳110的中心在竖直面的投影。也就是说，连接部件130与外壳110的连接处位于外壳110中心点水平线以上，如图1所示。这样能够保证连接部件130与外壳110的连接处和支脚111与外壳110的连接处沿外壳110的周向方向存在一定的距离，使得震动通过连接部件130传递到外壳110上后能够进行衰减，减少传递到支脚111上的震动值，进而降低压缩机在运行过程中传递给零件支撑部的震动值，保证压缩机运行稳定可靠。
作为一种可实施方式，连接部件130的形状为直线型、曲线形或者直线型与曲线形的拼接组合。连接部件130的形状原则上不受限制，只要能够保证支撑部件120与外壳110连接可靠机壳。在此基础上，为了增加连接部件130衰减震动的效果，可以适当增加连接部件130的长度，以增加震动的传递路径。在本实施例中，连接部件130为连接筋条，当然，连接部 件130还可以为其他能够实现外壳110与支撑部件120连接的零件。连接部件130的形状可以为直线型或者多个直线型零件拼接而成；连接部件130的形状也可为曲线形或多个曲线形零件拼接而成；当然，连接部件130的形状可以为直线型与曲线形的拼接组合。
进一步地，连接部件130的截面形状沿连接部件130的长度方向可以是渐变的，可以是逐渐增加或者逐渐减小，这样能够方便震动的传递，同时还能实现震动在连接部件130的传递过程中发生衰减。
在本实施例中，连接部件130呈直线型设置，这样能够保证支撑部件120与外壳110连接可靠，便于震动通过连接部件130传递到外壳110上。当然，在本申请的其他实施方式中，在保证支撑部件120与外壳110连接可靠的同时，连接部件130也可至少部分环绕支撑部件120设置。此时，连接部件130包括环绕部和设置在环绕部两端的连接部，连接部件130的两端分别通过连接部连接到支撑部件120上及外壳110上，环绕部至少部分环绕支撑部件120。这样能够增加连接部件130的长度，进而延长震动的传递路径，加强震动传递过程中的衰减，减少传递到支脚111上的震动值，进而降低压缩机在运行过程中传递给零件支撑部的震动值，保证压缩机运行稳定可靠。
再进一步地，连接部件130的数量为多个，多个连接部件130与外壳110的连接处分别沿外壳110的周向方向分布，且各连接部件130之间存在一定的间距。也就是说，各个连接部件130之间不存在相接触的部位，在图1所示的主视方向和左视方向的投影会存在重叠现象，只要保证各个连接部件130之间不接触机壳，这样能够避免震动交错而造成的支撑部件120的固定问题，同时还能保证震动传递可靠。各个连接部件130可以是沿外壳110的轴向方向成列设置的，并沿外壳110的周向方向分布；各个连接部件130也可沿外壳110的周向方向及轴向方向错列分布；各个连接部件130还可以是交错设置的，等等。
在本实施例中，多个连接部件130是呈放射状设置的，且多个连接部件130沿外壳110的周向方向均匀分布，这样能够保证支撑部件120受力均匀，保证支撑部件120与外壳110连接可靠，同时还能保证连接部件130的连接处和支脚111与外壳110的连接处之间沿外壳110的周向方向存在一定的距离，方便震动的传递，以实现震动的衰减。当然，在本申请的其他实施方式中，多个连接部件130也可沿外壳110的周向方向呈非均匀分布。
更进一步地，离支脚111最近的连接部件130和外壳110的连接处与支脚111和外壳110的连接处的圆心角的范围为50°～150°。也就是说，离支脚111最近的连接部件130和外壳110的连接处与支脚111和外壳110的连接处沿外壳110的周向方向是存在一定距离的，而离支 脚111稍远的其他连接部件130和外壳110的连接处与支脚111和外壳110的连接处沿外壳110的周向方向必然存在一定的距离，这样能够延长震动在外壳110上的传递路径，加强震动传递过程中的衰减，减少传递到支脚111上的震动值，进而降低压缩机在运行过程中传递给零件支撑部的震动值，保证压缩机运行稳定可靠。
需要说明的是，本申请的壳体结构100通过连接部件130与外壳110的连接处在支脚111上方来延长震动的传递路径，以实现震动在外壳110上的衰减，减小传递到支脚111上的震动值，同时还需考虑震源即支撑部件120周围结构的强度、变形量大小及均匀性等问题，以保证压缩机的运行可靠性及使用性能，此时，可以通过加强震源周围结构的厚度等方面入手。
本申请还提供了一种压缩机，包括电机、转子及上述实施例中的壳体结构100。电机的输出端与转子连接，且电机与转子均安装于壳体结构100的外壳110中，壳体结构100的支撑部件120支撑电机与转子的连接处。本申请的压缩机通过壳体结构100的支撑部件120支撑电机与转子，并通过连接部件130将支撑部件120上电机与转子产生的震动传递到外壳110上，并通过外壳110衰减震动后，再将震动传递到外壳110的支脚111上，以降低压缩机运行时的震动值，从而减小传递到支脚111上的震动值，进而降低压缩机最终传递给零件安装部200的震动值，提高压缩机运行的可靠性。
本申请还提供一种空调机组，包括上述实施例中的压缩机。本申请的空调机组通过压缩机实现制冷制热性能，降低空调机组运行时的震动值，提高空调机组运行的可靠性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书的记载范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
