Description

用于真空抽屉的焊接棒以及真空抽屉
技术领域
本发明涉及一种用于真空抽屉的焊接棒，所述真空抽屉用于食品抽真空，所述焊接棒具有基本载体，所述基本载体包括至少一个沿纵向方向在所述表面上伸展的焊丝。此外，本发明涉及一种具有相应的焊接棒的真空抽屉。
背景技术
抽真空设备包括真空泵，将适当的容器、例如以可密封的包袋的形式的容器置于所述真空泵中。焊接棒在所述室内延伸，所述焊接棒在竖直方向上是可调节高度的。由食品填充的容器置于真空室中，所述真空室随后经由盖气密地封闭，以便借助于真空泵产生室真空。因为焊接棒首先定位在打开位置中，也能够将空气从容器中抽出。随后，对焊接棒进行高度调节并且将包袋夹入焊接棒和配合部位之间。通过输送需要的焊接能量，包袋由于生热而密封。
对于焊接过程必须确保，均匀地接触焊丝，因为否则可能会出现焊丝的局部过热和相应的损坏。因为在焊丝由于热学而变长的情况下可能不能确保均匀的接触，迄今为止集成有相应的弹簧元件以补偿变长。
发明内容
本发明的主题在于下述目的，示出焊丝在焊接棒的基本载体上的替选的固定。
所述目的通过根据本发明的一种用于真空抽屉的焊接棒来实现，所述真空抽屉用于食品抽真空。焊接棒的有利的设计方案下文的主题。
根据本发明，在这种具有包括至少一个沿纵向方向在表面上伸展的焊丝的基本载体的焊接棒中提出，将焊丝在预紧力下固定在基本载体上，使得所述焊丝在其整个长度上以面贴靠在所述基本载体上。通过预紧力，使得加热丝在任何部位以面贴靠并且能够导出热量。否则加热丝在没有散热的部位上会过热。
理想地，加热丝单侧地或双侧地经由夹紧连接间接地或直接地固定在基本载体上。由于优选通过将焊丝的端部卡接到相应的夹紧件中将焊丝与基本载体夹紧连接，焊丝能够在一定的预紧力下柔性地固定在基本载体上。预紧力用于，在焊丝由于热而变长时，也确保焊丝和周围环境、即基本载体的均匀接触。
优选地，焊丝经过基本载体的横向边被引导到下侧上，并且在下侧上借助于夹紧连接固定在所述下侧上。优选地，基本载体包括端侧的半径区域，焊丝以面贴靠的形式围绕所述半径区域伸展。
优选地，在基本体上的固定借助于夹紧机构进行，尤其优选地，为焊丝的每个自由端部分别设有单独的夹紧机构。焊丝本身在单侧经由夹紧连接固定在夹紧机构上。夹紧机构在基本体上的固定原则上能够以任意的类型和方式进行，然而夹紧机构与基本载体的可拆卸的连接是优选的。
根据一个优选的实施方案变型形式，一个或多个夹紧机构在基本载体上的固定经由夹紧机构的至少一个钩来实现。所述钩能够悬挂在基本载体上。优选地，夹紧机构优选固定在基本载体的表面之下，并且钩悬挂在基本载体的表面的横向边上。
此外能够提出，在基本载体的表面之下，在所述基本载体上设有一个或多个锁紧钩，所述锁紧钩锁入到夹紧机构的相应的凹部中进而构成基本载体和夹紧机构之间的形状配合的连接。
在此借助于夹紧机构的设计方案的特别的优点为，夹紧机构能够用于实现杠杆作用或楔入作用。通过夹紧机构的钩住并且通过将所述夹紧机构引入到基本载体的下侧上，优选通过借助钩紧连接作为转动轴线的转动运动，自动地实现所钩住的焊丝的足够的预紧力。
优选地，夹紧机构由导电材料构成或者包括至少一种导电材料，优选为导电金属。夹紧机构在该情况下同时用作为用于焊丝供电的连接部位。可设想在夹紧机构的下侧上的相应的开口，所述开口在将焊接棒安装在真空抽屉之内时能够插到相应的连接栓上。
为了提供夹紧连接，夹紧机构有利地包括槽，焊丝能够通过夹紧机构的挤压件压入到所述槽中。挤压件本身能够可运动地、尤其可弯曲地设置在夹紧机构上。
除了根据本发明的焊接棒之外，本发明还涉及一种真空抽屉，尤其用于安装到家具中，所述真空抽屉具有真空室和至少一个安装在真空室中的根据本发明的焊接棒。因此，根据本发明的真空抽屉的优点和特征对应于根据本发明的焊接棒的优点和特征。出于所述原因不进行重复说明。
附图说明
本发明的其他的优点和特征在下文中根据在附图中示出的实施例来详细阐述。附图示出：
图1a、1b示出根据本发明的真空抽屉的两个等轴图，
图2示出根据本发明的焊接棒的框架部件的立体图，
图3示出根据图2的框架部件的分解图，
图4示出根据本发明的焊接棒的横向于其纵轴线的截面图，
图5a示出基本载体沿着纵轴线的截面图，
图5b示出根据图5a的视图的细节图，并且
图6示出焊接棒的基本载体的分解视图。
具体实施方式
两个附图1a、1b示出根据本发明的真空抽屉的等轴图。图1a的视图示出用于常规抽真空运行的移出的抽屉。在图1b中，抽屉为了维护目的再继续移出一部分，以便能够看到真空泵30。抽屉适合于用在厨房家具中，因为所述抽屉的特征在于大约140mm的安装高度进而对应于一体化厨房(Einbauküchen)的标准尺寸。
真空抽屉包括抽屉抽出部分10，所述抽屉抽出部分在抽屉柜体12中经由侧面的引导轨道以纵向移动的方式被引导。在示出的实施例中，前盖11是无把手的，抽屉抽出部分构造成用于打开和关闭的推拉装置。在抽屉抽出部分之内安装有真空室20，所述真空室与真空抽屉的真空泵30流体地耦联，以便将空气从封闭的真空室20中泵出。真空泵20能够经由可枢转地安装在室20上的盖21气密地封闭。盖21本身能够出于设计原因由玻璃制成。
焊接棒22用于密封所置入的包袋，所述焊接棒在室内部中沿抽屉的抽出方向延伸。为了抽真空，将用食品填充的包袋置于室20中并且将盖21气密地封闭。在将室20借助于在图1b中可见的真空泵30泵吸之后，包袋能够借助于焊接棒22密封。对此，将待密封的包袋开口放置在焊接棒22上，在抽真空之后，所述焊接棒将所述包袋开口压靠到按压部位上并且通过生热密封。棒22要么能够按压到固定在盖21上的配合压棒23上，要么能够压靠到替选的按压面上。真空泵30在室20的后面位于抽屉抽出部分10的后部上并且与真空室20流体地耦联，以便将空气从室20中泵出，以产生真空。
焊接棒22包括基体40以及框架部件25，所述框架部件配设有特氟龙带26。在焊接过程中，焊接棒22经由特氟龙带26接触所放置的包袋，借助焊丝42产生的热经由特氟龙带26输出到包袋上。图2示出用于根据本发明的焊接棒22的框架部件25的立体图。框架部件25包括特氟龙带26，所述特氟龙带沿焊接棒22的纵向方向几乎完全在焊接棒表面上延伸。
焊接棒22的由基体40和框架部件25构成的两件式的构造允许快速地、简单地并且低成本地更换特氟龙带26。能够更换整个框架部件25或者仅更换特氟龙带26。
根据图3的分解图示出整个特氟龙带26以及框架部件25的表面的特性。框架部件25在其表面27上包括凹部28，在焊接过程期间将相应待密封的包袋安放到所述表面上。特氟龙带26的长边29向下折叠，因此特氟龙带26的所得到的宽度大致对应于凹部28的开口宽度。由此，特氟龙带26能够插入到开口28中，并且得到框架25的几乎无阶梯的表面27，其中在框架部件25和特氟龙带26之间的过渡部上具有极其小的错位。
然而，特氟龙带26的折叠棱边31不是简单的折角(Kantung)，而是折叠形成弯曲的阶梯形的轮廓31。准确的轮廓变化可从根据图4的横剖图中得出。通过选择的轮廓形状31，特氟龙带26能够紧密地贴靠到框架部件25的两个密封唇32上，所述密封唇分别沿着开口28的长边延伸。密封唇32造成框架部件25和特氟龙带26之间的过渡部中的错位，从而最小化在过渡部上形成污物的风险。
此外，从图4中可得知，将框架部件25从上方插到焊接棒22的基本载体40上。在框架部件25的开口28的开口边的区域中，内壁部33向内或向下伸入到焊接棒22中，由此形成开口壁部。所述内壁33平行于基本载体40的相对置的侧壁41伸展。内壁部33此外平行于框架部件25的相应的外壁34伸展。在内壁33和外壁34之间存在间隙。
焊丝42在基本载体40的表面45上沿纵向方向伸展。如果将框架部件25从上方插到基本载体40上，那么焊丝42直接位于特氟龙带26之下，由此得到优化的热传递。特氟龙带26能够通过夹紧连接固定在焊接棒22上。对此，折叠的长边29夹紧在基本载体40的侧壁部41和框架部件25的内壁部33之间。同样地，在密封唇32的区域中实现与基本载体40的表面的密封的夹紧。特氟龙带26此外能够与框架部件25附加地粘接或者以其他的方式固定在框架部件上。
在将框架部件25插到基本载体40上时，内壁部33的下部边在端侧卡接到基本载体40的通过凸缘43形成的槽44中。
焊丝42在基本载体40上的固定在下文中根据图5a、5b和6详细阐述。图6示出基本载体40的分解视图，而图5a示出贯穿基本载体40的纵剖面。图5b示出根据图5a的基本载体40的右侧的细节局部图。
焊丝42在基本载体40的整个表面45上沿纵向方向张紧，其中自由的焊丝端部经过基本载体40的端部边引导到基本载体的下侧上。焊丝42在基本载体40上的固定借助夹紧机构50来实现。所述夹紧机构由导电材料制成并且同时提供焊接棒22的连接部位以用于供电。
在夹紧机构50的上侧上存在钩51，所述钩通过夹紧机构50的倒圆的端部边56形成。在夹紧机构50的下侧上存在槽53以及可弯曲地固定在夹紧机构上的桩52，所述桩能够精确配合地压入到槽53中。在夹紧机构50的上侧上存在凹部55，另一个凹部54存在于夹紧机构50的后侧上。焊丝42的自由端部分别经过夹紧机构50的倒圆的端侧56从上侧向下跨越槽53地放置，并且其通过将桩52压入到槽53中的方式夹紧地固定在夹紧机构50上。
随后，两个夹紧机构能够经由钩51在端侧悬挂在基本载体40上。优选地，钩从上部悬挂在基本载体上并且随后通过转动运动向内按压到基本载体的下侧之下。通过与之关联的杠杆作用，产生焊丝的足够的应力，使得所述焊丝均匀地并且平面地在基本载体40的上侧45上伸展。预紧力选择成，使得在焊丝42由于热变长的情况下也出现均匀的接触。在所述位置中，夹紧机构50此外经由凹部54、55锁紧在基本载体40的相应的锁紧钩47、48上。然而，值得注意的是，夹紧机构50在固定位置中受保护地位于夹紧体50的空腔中。
