Description

具有包括簧片阀的压缩机的家用器具
技术领域
本申请涉及一种具有压缩机的家用器具，该压缩机包括簧片阀。
背景技术
家用器具、尤其是空调或冰箱，通常包括压缩机，压缩机带有阀，阀打开和关闭以吸入或排出制冷剂。通常在这种压缩机中，用于将制冷剂从吸入室吸入缸膛的吸入孔和用于将压缩的制冷剂从缸膛排放到排放室的排放孔形成在位于缸盖和缸膛之间的阀板中，并且用于打开和关闭吸入孔和排放孔的簧片阀结构的吸入阀和排放阀附连到阀板。在这种情况下，阀座通常形成在吸入孔和排出孔中的每个的外周部分中。阀打开时，当来自缸膛的负吸入压力或排出压力增加并且等于或高于阀打开压力时，阀打开。然而，此时由于吸入脉动或排出脉动而产生的压力脉动会增加压缩机的噪音并降低其效率。
公开文件EP 2 685 103 A1描述了一种用于压缩机的阀装置，该阀装置具有簧片阀结构，包括：阀板，其中形成有阀孔，该阀孔被打开和关闭以吸入或排出制冷剂；阀座，其形成在阀板中的阀孔的外周部分中，从而以凸台形状突出到围绕其外侧形成的凹槽中；以及阀体，该阀体具有连接到阀板的近端以及允许与阀座的座表面自由接触和脱离接触的远端，其中阀座或包括阀座的周边部分形成为使得对应于阀体远端侧的部分相对于对应于阀体近端侧的部分得到加强。得到了噪声抑制效果。
公开文件EP 0 926 345 A2描述了一种具有排出阀机构的压缩机，该排出阀机构包括阀板，该阀板具有至少一个用于在活塞缸和排出室之间提供流体连通的排出通道、排出阀簧和阀保持器，并且所述至少一个排出通道包括具有一面积的第一活塞缸侧开口、具有一面积的排出室侧开口和在所述开口之间延伸的侧壁，其中，所述排出通道侧壁的至少一部分是渐缩的，其中，所述排出室侧开口面积大于所述第一活塞缸侧开口面积。
发明内容
鉴于这种情况，本申请的目的是提供一种具有压缩机的家用器具，该压缩机包括簧片阀，在该簧片阀中可以实现显著的噪音降低。
根据本申请，该目的通过具有根据本申请的一个方面的家用器具来实现。在根据本申请的其他方面中公开了家用器具的优选实施例。
因此，本申请涉及一种具有包括簧片阀的压缩机的家用器具，其中，簧片阀是带锯齿簧片阀和/或阀座包括选自多孔材料、突起或阀座锯齿的扰流减少结构。
“带锯齿”通常是指在簧片阀的边缘处、特别是用于打开和关闭排放口的头部的边缘处设置有锯齿结构。相应的锯齿可以从边缘垂直地或倾斜地延伸。
为了减少扰流并因此减少噪音，可以调整锯齿的形状、高度、宽度、倾斜度、突起的形状以及多孔材料的孔的数量或孔直径。
在本申请的家用器具中，对压缩机没有特别的限制，只要它包括簧片阀。压缩机可以是例如往复式压缩机、涡旋式压缩机或滚动转子旋转式压缩机。
在家用器具的一个优选实施例中，压缩机是滚动转子旋转式压缩机。
此外，包括热泵的家用器具是优选的。
一般来说，家用器具是优选的，其中家用器具选自由干衣机、洗衣干衣两用机、洗碗机、空调和家用热泵组成的组。更优选地，家用器具是干衣机或洗衣干衣两用机。
在本申请家用器具的一个优选实施例中，簧片阀是带锯齿簧片阀。优选的是，带锯齿簧片阀上的锯齿在排放口的方向上定向。
对本申请中应用的锯齿没有特别限制。然而，家用器具是优选的，其中带锯齿簧片阀的锯齿包括锯齿峰和锯齿谷。优选地，锯齿峰具有相同的高度，锯齿谷具有相同的深度。锯齿峰的高度可以称为2h，且锯齿形状的节距、即例如三角形的底边可以称为λ。在圆形的带锯齿边缘的情况下，该节距可以称为旋周节距。由未完全连接到簧片阀的两个边缘所限定的角度可以称为2θ。
在家用器具的一个优选实施例中，由簧片阀限定的平面和锯齿所在的平面之间的角度
Figure BDA0003637761870000031
在0°到60°的范围内。
为了降低噪音，锯齿高度、特别是三角形的高度(2h)、以及上述的其他锯齿参数将针对包括压力、温度和气体/制冷剂类型的标称工作条件进行调整。
簧片阀通常包括用于关闭排放口的头部和固定在阀座主体上的根部。
本申请中使用的压缩机通常包括阀簧保持器。也就是说，在通常的工作条件下，压缩机的压缩室中的压力增加，直到压力高于由阀施加的力，特别是高于阀簧另一侧的压力，阀簧通常是由例如钢制成的平金属片。带锯齿阀将打开以允许排出气体流动。阀簧保持器的作用是避免簧片阀的大变形。根据工作条件(压缩空气/制冷剂的压力和温度)，簧片阀将或多或少地抬起，并且大的偏转可能在簧片阀中产生塑性变形。保持器是防止塑性或永久变形的止动件。
阀簧将被提升，并且压缩气体/制冷剂将高速流过排放口。
本申请具有的优点是，提供了一种具有包括簧片阀的压缩机的家用器具，其中，可以实现显著的噪音降低。

具体实施方式
图1示出了可用于本申请的压缩机1的示例，即处于四种工作状态的滚动转子旋转式压缩机1。滚动转子旋转式压缩机1包括缸7，滚动转子6在缸7中绕曲轴8旋转。冷却剂(这里例如空气)通过吸入口2被引入。附图标记11表示吸入空气的流向。被吸入的空气由滚动转子6朝排放口3的方向输送(例如参见A)。滚动转子6的偏心运动将增压区9(见B和C)与被吸入的空气分开。此外，柔性布置的叶片5也将吸入和排出的空气流分开。在排放口3上设置有带锯齿簧片阀4，该簧片阀4在A处于关闭位置，在D处于打开位置。因此，压缩空气可以在D通过排放口3离开缸。附图标记10表示排放气体的流动方向。
图2在上部以侧视图示出了带锯齿簧片阀4，其通过螺栓13固定在阀座17上。附图标记3表示排放口，排放口在这里为圆形。阀簧保持器12保护带锯齿簧片阀4免受可能导致带锯齿簧片阀4过度变形的扰动。附图标记18表示簧片阀4的锯齿。在图2的下部，示出了带锯齿簧片阀4的俯视图。带锯齿簧片阀4包括头部15和带有孔14的根部16，孔14用于用螺栓(这里未示出)固定带锯齿簧片阀。头部15是大致圆形的，因此适于排放口的圆形形状。这里可以更详细地看到锯齿18。
图3示出了带锯齿簧片阀4的侧视图，其中，锯齿18在头部处以角度
Figure BDA0003637761870000041
倾斜。附图标记18表示锯齿，附图标记15表示簧片阀14的头部，附图标记17表示阀座17，附图标记3表示排放口。
图4示出了a)根据现有技术的无锯齿簧片阀19，即没有锯齿的簧片阀，以及b)本申请中使用的带锯齿簧片阀4。附图标记18表示锯齿，附图标记15表示簧片阀14的头部，附图标记16表示簧片阀4的根部。
图5示出了图4b)中所示的带锯齿簧片阀4的透视图。附图标记具有与图4b)中相同的含义。
图6详细示出了带锯齿簧片阀4的头部15的一部分，其中，可以详细看到锯齿18。锯齿18在这里由具有等距的锯齿谷24和锯齿峰25的大致三角形结构形成。(旋周)节距λ、即节距23，是相应三角形的底边。底周和锯齿峰25之间的距离21是锯齿的长度(2h)21。角度2θ、即角度22由未完全连接到簧片阀或翼边缘的两个边缘限定。附图标记10表示排出气体的流动方向。
