Description

把手组件及具有其的家用电器 技术领域
本申请涉及家用电器领域，具体而言，涉及一种把手组件及具有其的家用电器。
背景技术
目前现有的家用电器(例如冰箱)上的把手一般通过明把手的安装方式进行安装，即把手通过固定螺丝固定在门体上。但是，家用电器安装明把手后，会造成家用电器整机包装体积增大，造成在同样空间下，可以运输家用电器的数量偏小，特别是对于出口型家用电器，单个集装箱运费固定且昂贵。
因此，为了提高单个集装箱内装箱数量，目前常用做法是将家用电器明把手先不安装，从而减小单台家用电器体积，待家用电器运到用户家后再在用户家安装把手。但是，由于现有把手需要专用工具才能安装好，需要售后人员上门安装，从而导致增加家用电器的成本。
发明内容

下面结合图1-图19详细描述根据本申请实施例的把手组件。
参照图10、图11、图15、图19所示，根据本申请实施例的把手组件可以包括：安装组件11和把手20，把手20适于与安装组件11进行配合。
进一步地，安装组件11包括：预装件111和伸缩元件112，预装件111可以预先安装到把手20所需安装的物体上，例如在将把手组件应用于家用电器时，安装组件11可以位于家用电器的箱门10上，预装件111与箱门10固定连接，例如，预装件111可以预先埋到箱门10的发泡层中。
预装件111上开设有把手槽1111，在一些可选的实施例中，把手槽1111位于预装件 111的上下两端，伸缩元件112可至少部分地伸入所述把手槽111内，具体地，安装组件11位于箱门10的内侧中，且把手槽1111露在箱门10的外侧，把手20通过与安装组件11的配合可以安装在家用电器的箱门10上，用户可以通过把手20拉动箱门10，从而打开或关闭家用电器，以方便使用家用电器。
为了描述方便，以家用电器为冰箱100为例来说明把手组件的装配。
在具体实施例中，生产冰箱100的箱门10时，预装件111可以预先安装到箱门10的内部发泡层中，从而可以为设置伸缩元件112以及挡盖113提供支撑，且把手槽1111可露在箱门10的外侧，从而为把手20可固定在箱门10上提供了可能。进一步地，如图13、图17所示，把手20上设置有限位凸台21，限位凸台21适于设置在把手槽1111内，具体地，伸缩元件112可至少部分地伸入把手槽1111内，把手20上设置有限位凸台21，且限位凸台21适于设置在对应的把手槽1111内，限位凸台21还可在把手槽1111中进行上下移动，在一些实施例中，把手20的上下两端均设置有限位凸台21，把手20的上下两端的限位凸台21之间的距离与预装件111的上下两端的把手槽1111之间的距离相等，从而保证把手20的上下两端的限位凸台21可以与预装件111的上下两端的把手槽1111顺利配合，从而保证把手20的固定牢靠。
具体地，限位凸台21上开设有限位槽213，限位槽213构造成在伸缩元件112伸入限位槽213的情况下将把手20的位置固定，限位槽213为贯穿限位凸台21的通孔，当限位凸台21在把手槽1111中向下移动时，伸缩元件112会伸入限位槽213时，此时，把手20的位置固定。也就是说，把手20上中上下两端的限位凸台21至少一个会设有限位槽213，例如，仅把手20的上端设有限位槽213，或者仅把手20的下端设有限位槽213，再或者把手20的上下端均设有限位槽213。
需要说明的是，当仅把手20的上端设有限位槽213时，对应地，仅在预装件111的上方设有伸缩元件112、弹性元件114以及挡盖113；同样的，仅把手20的下端设有限位槽213时，仅在预装件111的下方设有伸缩元件112、弹性元件114以及挡盖113；再或者把手20的上下端均设有限位槽213时，则在预装件111的上下两端均设有伸缩元件112、弹性元件114以及挡盖113。
下面为了更好的说明把手20与箱门10的配合过程，如图8-图18所示，以仅在把手20的上端设置限位槽213且把手20沿竖直方向设置为例，来说明把手20与箱门10的配合的过程。
在具体实施例中，当冰箱100送到用户的家后，把手20与箱门10是分开的，当用户需要安装把手20时，首先，将把手20的上下两端的限位凸台21分别与露在箱门10外侧的上下两端的把手槽1111进行配合，其次，将把手20向下移动(即下面所说的沿把手槽 1111向伸缩元件112方向移动)，此时，把手20上端限位凸台21的限位槽213与伸缩元件112发生对齐，并且伸缩元件112的一部分会伸入到限位槽213中，限制了限位凸台21的上下运动，从而将把手20的限位凸台21限制在把手槽1111中(即将限位凸台21锁死)，可以防止把手20从把手槽1111中脱落，进而完成把手20的安装。
并且，当用户需要拆卸把手20时，可以利用可穿入限位槽213的细棍，通过穿入限位槽213将伸缩元件112退出把手槽1111，使伸缩元件112从限位槽213退出，从而将把手20从把手槽1111中取出，进而完成把手20的拆卸。
根据本申请实施例的把手组件，在把手20上设置限位凸台21，且限位凸台21上还设有限位槽213，且安装组件11中的预装件111设有把手槽1111，通过限位凸台21与把手槽1111进行配合，可以完成把手20与预装件的装配，并且安装组件11中的伸缩元件112的一部分可以伸入到限位槽213中，将把手20锁止，保证把手20安装的可靠性高，从而实现在不需要其他专用工具的情况下，用户自己便可将把手20安装在所需安装的物体(例如箱门10)上，从而提升用户的体验感，且把手20安装简单、可靠。
进一步地，参考图1-图2、图5、图7、图13、图17所示，预装件111上开设有卡槽1112，卡槽1112与把手槽1111连通，且卡槽1112的轴线方向与把手槽1111的截面垂直，伸缩元件112适于在卡槽1112内移动，并可至少部分地伸入把手槽1111内。也就是说，通过设置卡槽1112，为伸缩元件112提供了移动轨道，即可以为伸缩元件112的移动方向进行导向，且伸缩元件112的一部分还可伸入到把手槽1111中，从而为伸缩元件112可以伸入到限位槽213中提供了可能。通过设置卡槽1112，可以保证伸缩元件112的移动方向，从而保证伸缩元件112可以锁止限位凸台21，保证把手组件的工作可靠性较高。
进一步地，参考图1-图2、图5、图7、图13、图17所示，安装组件11还可以包括：弹性元件114，弹性元件114为弹性件，弹性元件114位于安装组件11中时，始终处于被压缩状态，在具体实施例中，弹性元件114与伸缩元件112相连且用于将伸缩元件112向把手槽1111所在方向推动，也就是说，弹性元件114同样位于卡槽1112内，且与伸缩元件112接触相连，在弹性元件114的弹力下，可以将伸缩元件112朝向把手槽1111所在方向进行推动，从而可以将伸缩元件112的一部分推入到把手槽1111中。
进一步地，如图2、图7所示，伸缩元件112具有导向斜面112b，导向斜面112b被构造成：在把手20沿把手槽1111向伸缩元件112方向移动的情况下，把手20挤压导向斜面112b，以使伸缩元件112退出把手槽1111；伸缩元件112被构造成：在限位槽213与卡槽1112对齐的情况下，伸缩元件112在弹性元件114的弹力作用下从卡槽1112进入限位槽213内。
也就是说，在伸缩元件112伸入把手槽1111的一端设有导向斜面112b，具体地，导向 斜面112b的延伸方向朝向冰箱100外侧的斜下方，因此，当把手20沿把手槽1111向伸缩元件112方向移动时(即向把手20的下方移动)，把手20的限位凸台21会与伸缩元件112伸入到把手槽1111的部分(即伸缩元件112的导向斜面112b)接触，随着把手20进一步地向下移动，把手20的限位凸台21会向下挤压伸缩元件112，由于导向斜面112b的延伸方向朝向冰箱100外侧的斜下方，因此，伸缩元件112会受到朝向箱门10内侧方向的分力，所以，伸缩元件112会朝向箱门10内侧方向移动，退出把手槽1111中，此时，弹性元件114进一步地被压缩，当把手20进一步地向下移动时，此时，伸缩元件112会与把手20的限位槽213对齐，在弹性元件114的弹性作用下，将伸缩元件112推入到限位槽213中，从而完成把手20的安装。
通过在伸缩元件112上设置导向斜面112b，为伸缩元件112在受限位凸台21的挤压时，提供了导向，保证伸缩元件112可以退出把手槽1111，从而保证把手20可以下移到安装位置，并且伸缩元件112可以伸入到限位槽213中，进而完成把手20的安装。
进一步地，如图7、图13-图14、图17-图18所示，把手槽1111具有限位台阶1111a，也就是说，把手槽1111为具有台阶的槽，且限位台阶1111a位置处为内部掏空的倒扣结构。
进一步地，参考图9所示，限位凸台可以为T形凸台21，T形凸台21可以包括：长凸台211和短凸台212，长凸台211与短凸台212固定连接，具体地，长凸台211的长度大于短凸台212的长度，短凸台212的两端分别与长凸台211以及把手20固定连接，且长凸台211朝远离把手20的方向延伸。长凸台211的长度小于或等于把手槽1111的长度，以便长凸台211可以进入把手槽1111内。
当然，限位凸台还可以为十字型凸台等。
在具体实施例中，长凸台211适于在把手槽1111内移动，且短凸台212可以被构造成在限位槽213与卡槽1112对齐的情况下，夹持在两个限位台阶1111a之间，即当限位槽213与卡槽1112对齐时，短凸台212夹持在两个限位台阶1111a之间，从而可以限制把手20直接从把手槽1111中取出，限制了把手20的前后左右方向移动，有利于提高把手20与箱门10配合的可靠性。又由于伸缩元件112的一部分卡在限位槽213中，限制了把手20的上下运动，至此，实现把手20在箱门10上的安装。
进一步地，限位台阶1111a的内表面与把手槽1111的槽底间隔开，便于长凸台211进入限位台阶1111a与把手槽1111槽底之间的间隙中,从而使T形凸台21的长凸台211可以卡滞在把手槽1111中。
进一步地，长凸台211的厚度与限位台阶1111a和把手槽1111槽底之间的间隙相等或者略小于该间隙，防止T形凸台21在把手槽1111内晃动。
具体地，限位台阶1111a的高度至少大于长凸台211的高度的一半，即如图2所示， 限位台阶1111a朝上方延伸的高度尺寸大于长凸台211的高度尺寸的一半，从而防止把手20从把手槽1111中脱落，保证限位可靠，从而保证把手20安装的可靠性高。
具体地，如图1-图2、图5、图7、图13、图17所示，安装组件11还可以包括：挡盖113，挡盖113位于安装组件11的最内侧，并且与预装件111固定连接，挡盖113将弹性元件114限制在卡槽1112内，防止弹性元件114从预装件111朝向箱门10内侧的方向弹出，保证弹性元件114可以始终位于卡槽1112中，为伸缩元件112提供支撑。
可选地，弹性元件114为弹簧，弹簧的弹性较好，可以保证当伸缩元件112向箱门10内侧移动时，弹性元件114因为受压，从而为伸缩元件112提供朝向箱门10外侧移动的力，保证伸缩元件112可以及时地将把手20锁止。
具体地，预装件111可与箱门10集成为一体，也就是说，把手槽1111直接形成在箱门10上，减少了预装件111这个零件，从而减少了预装件111与箱门10的装配工序，有利于节省冰箱100的装配工时。
优选地，预装件111与箱门10可以采用发泡固定的方式，此时预装件被作为一种预埋件，即预装件111预埋在箱门10内部后，通过在箱门10内注入液体发泡料，通过发泡料化学反应最终膨胀包裹住预装件111，从而固化成形状稳定的箱门10。
根据本申请另一方面实施例的家用电器，包括箱门10以及把手组件，安装组件11设置在箱门10上。在具体实施例中，家用电器除了可以为上述的冰箱100，还可以是消毒柜、微波炉、烤箱等。
进一步地，预装件111与箱门10集成为一体，从而可以简化把手20的安装步骤，保证把手20安装较为简单，并且还可以降低包装家用电器的占用空间，从而有利于降低运输成本。下面结合图1-图19具体描述把手组件在冰箱100上的安装与拆卸过程：
需要安装把手20时，首先将预装件111安装在箱门10上，再把手20的限位凸台21插入预装件111的把手槽1111内，此时箱门10与把手20的位置关系如图11-图14所示，然后将把手20朝箱门10的下方移动，使把手20的限位凸台21的短凸台212滑入限位台阶1111a内，同时，伸缩元件112的导向斜面112b在限位凸台21的挤压下退出把手槽1111，当把手20继续移动到限定位置时，长凸台211卡在限位台阶1111a与把手槽1111的槽底之间，伸缩元件112会与把手20的限位槽213对齐，在弹性元件114的弹性作用下，将伸缩元件112推入到限位槽213中，此时把手20安装到位并被锁死，从而完成把手20的安装。
需要拆卸把手20时，可以利用可穿入限位槽213的细棍，通过穿入限位槽213将伸缩元件112推出把手槽1111，然后将把手20朝箱门10的上方移动，从而将把手20从把手槽1111中取出，进而完成把手20的拆卸。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。此外，本领域的技术人员可以将本说明书中描述的不同实施例或示例进行接合和组合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
