Description

一种门封及具有该门封的制冷容器 技术领域
本发明涉及冰箱门体密封技术领域，尤其涉及一种门封及具有该门封的制冷容器。
背景技术
冰箱门需要频繁开启，为保证冰箱的密封，防止冰箱门关闭不够严密而导致冰箱漏冷现象的发生，在冰箱的门体与箱体外壳的接触面设置了门封，以实现密封。门封设有密封气囊和卡舌，通过卡舌与门体内胆的卡接将门封固定在门体上，由密封气囊实现门体的密封。
冰箱门体在关闭时，门封的密封气囊由于受压力而产生变形，使得在开启门体时，需要克服一定负压才能使密封气囊由压缩状态变到拉伸状态。为了实现冰箱门体的顺利开启，现有技术中在密封气囊的主气囊的左、右两侧开设有通孔，用于在开启门体时使空气通过该通孔进入冰箱箱体内，以使箱体内外压力达到平衡，从而便于门体的开启。由于该通孔开设在主气囊上，为保证密封性，其孔径不能太大，一般设为3mm，否则将会影响外观，并出现漏冷、结霜等不良现象。而孔径较小的通孔并不能起到较好的导通空气的作用，使得冰箱门体开启时需要较大的开启力。
发明内容
(一)要解决的技术问题
本发明提供一种门封及具有该门封的制冷容器，以解决现有门封在主气囊的两侧开设通孔使得门体开启力大的问题。
(二)技术方案
为了解决上述技术问题，本发明提供了一种门封，包括：密封气 囊部和卡舌部，卡舌部用于与门体连接，卡舌部包括倒刺和用于连接倒刺与密封气囊部的固定板，密封气囊部与固定板通过连接部连接，且密封气囊部与固定板之间形成间隙，固定板位于倒刺与连接部之间的位置上开设有若干个通孔。
根据本发明，连接部位于靠近密封气囊部的侧壁的位置。
根据本发明，通孔呈长条型或U型。
根据本发明，通孔的最大内径为20-60mm。
根据本发明，固定板的一端设有飞边，飞边由固定板的一端部向倒刺的一侧弯折形成。
根据本发明，密封气囊部的一侧壁朝远离固定板的方向延伸出有叶边。
根据本发明，密封气囊部包括内侧气囊和位于内侧气囊两侧的外侧气囊，内侧气囊和外侧气囊内分别设有若干个支撑筋。
根据本发明，密封气囊部还包括设于外侧气囊外侧的耳状气囊，耳状气囊的外侧面呈弧形面。
本发明还提供了一种制冷容器，具有如上所述的门封。
(三)有益效果
本发明的上述技术方案提供的门封及具有该门封的制冷容器具有如下优点：
通过连接部将固定板与密封气囊部连接，且固定板与密封气囊部之间具有间隙，并将通孔设置在固定板位于倒刺与连接部之间的位置上，由此，当门体关闭时，门封的密封气囊部被压变形而抵压在固定板上，将固定板上的通孔堵住，因此不影响密封效果；当门体开启时，密封气囊部在负压作用下随门体的运动而离开固定板，使得空气能够从固定板上的通孔和固定板与密封气囊部之间的间隙进入箱体内而使箱体内外压力达到平衡，从而使门体能够轻易开启。由于通孔设在固定板上而不影响外观，且门体关闭时通孔被密封气囊部压盖堵住而 不影响密封，因此，通孔的尺寸可以根据需要设置为较大的尺寸，以达到良好的导通空气的作用，使得空气在门体开启时能够瞬间进入箱体，从而缩短门体开启时间，提升用户手感。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1和图2所示，本发明的门封的一种实施例。本实施例的门封包括密封气囊部10和卡舌部20，卡舌部20设于密封气囊部10下方。卡舌部20用于与门体连接，卡舌部20包括倒刺201和固定板202，倒刺201能够与门体内胆上设置的卡槽卡接固定，固定板202用于连接倒刺201与密封气囊部10，以将密封气囊部10固定在门体上。密封气囊部10与固定板202通过连接部30连接，且密封气囊部10与固定板202之间具有间隙。在固定板202位于倒刺201与连接部30之间的位置上开设有通孔40，即通孔40设置在固定板202靠近连接部30的位置上。通孔40可以设有一个或多个，优选为1至5个。通孔40用于在开启门体时使空气通过该通孔40进入与门体连接的箱体内，以使箱体内外压力达到平衡，从而便于门体的开启。需要 说明的是，本文中的“左”、“右”、“上”、“下”是指本实施例的门封如图2所示地放置时的位向。
本实施例的门封，通过连接部30将固定板202与密封气囊部10连接，使得固定板202与密封气囊部10之间具有间隙，并将通孔40设置在固定板202位于倒刺201与连接部30之间的位置上，由此，当门体关闭时，门封的密封气囊部10被压变形而抵压在固定板202上，将固定板202上的通孔40堵住，因此不影响密封效果；当门体开启时，密封气囊部10在负压作用下随门体的运动而离开固定板202，使得空气能够从固定板202上的通孔40和固定板202与密封气囊部10之间的间隙进入箱体内而使箱体内外压力达到平衡，从而使门体能够轻易开启。由于通孔40设在固定板202上而不影响外观，且门体关闭时通孔40被密封气囊部10压盖堵住而不影响密封，因此，通孔40的尺寸可以根据需要设置为较大的尺寸，以达到良好的导通空气的作用，使得空气在门体开启时能够瞬间进入箱体，从而缩短门体开启时间，提升用户手感。
进一步，在本实施例中，连接部30位于靠近密封气囊部10的侧壁的位置。优选地，连接部30由密封气囊部10的右侧壁从密封气囊部10的下表面朝向固定板202延伸。由此，连接部30与固定板202构成L型的连接结构，使得门体开启时，开启力仅从卡舌部20经连接部30传递至密封气囊部10的一侧，大大缩短了开启力的传递路径，且门体开启时门封从其密封气囊部10受力的一侧撕开，因此减少了门体开启时密封气囊部10由压缩状态到拉伸状态克服负压的行程，并减少了门体开启所需的开启力，从而缩短了开启时间，提升了用户手感。
进一步，在本实施例中，通孔40可以为长条型或U型，通孔40可以设置一个，也可以沿着门封的长度方向间隔设置2-5个。通孔40的最大内径可以为20-60mm。由此，可以大大增加通孔40导通空 气的能力，使得空气在门体开启时能够由通孔40瞬间进入箱体，从而缩短门体开启时间。
进一步，在本实施例中，固定板202的一端设有飞边2021，飞边2021由固定板202的一端部向倒刺201的一侧弯折形成。本实施例的门封安装在门体内胆上时，飞边2021搭在门体内胆上，可以将门体内胆的边缘遮盖起来，从而提高门体的外部美观性。
进一步，在本实施例中，密封气囊部10设有连接部30的右侧壁朝远离固定板202的方向延伸出有叶边101。叶边101与密封气囊部10的右侧壁外表面形成一光滑面，便于用户对门封进行清洁。
进一步，在本实施例中，密封气囊部10包括内侧气囊102和位于内侧气囊102两侧的外侧气囊103，内侧气囊102和外侧气囊103内分别设有若干个支撑筋。具体地，内侧气囊102内从上至下间隔设有三条水平的支撑筋1021，将内侧气囊102分成三个子气囊。外侧气囊103内设有一条水平的支撑筋1031，将外侧气囊103分成两个子气囊。在左侧外侧气囊103的外侧，还设有呈耳朵状的耳状气囊104，耳状气囊104的外侧面呈弧形面。由此，本实施例的密封气囊部10具有较好的稳定性和弹性，能够保证门封具有良好的密封性。
综上所述，本实施例的门封，通过连接部30将固定板202与密封气囊部10连接，使得固定板202与密封气囊部10之间具有间隙，将通孔40设置在固定板202上靠近连接部30的位置而不影响外观，且门体关闭时通孔40被密封气囊部10压盖堵住而不影响密封，因此，通孔40的尺寸可以根据需要设置为较大的尺寸，以达到良好的导通空气的作用，使得空气在门体开启时能够瞬间进入箱体，从而缩短门体开启时间，提升用户手感。
本实施例还提供了一种制冷容器，本实施例的制冷容器具有本实施例的上述门封。本实施例的制冷容器可以是冰箱或冷柜。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而 非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
工业实用性
本发明提供了一种门封，包括：密封气囊部和卡舌部，卡舌部用于与门体连接，卡舌部包括倒刺和用于连接倒刺与密封气囊部的固定板，密封气囊部与固定板通过连接部连接，且密封气囊部与固定板之间形成间隙，固定板位于倒刺与连接部之间的位置上开设有若干个通孔。通过连接部将固定板与密封气囊部连接，且固定板与密封气囊部之间具有间隙，并将通孔设置在固定板位于倒刺与连接部之间的位置上，由此，当门体关闭时，门封的密封气囊部被压变形而抵压在固定板上，将固定板上的通孔堵住，因此不影响密封效果；当门体开启时，密封气囊部在负压作用下随门体的运动而离开固定板，使得空气能够从固定板上的通孔和固定板与密封气囊部之间的间隙进入箱体内而使箱体内外压力达到平衡，从而使门体能够轻易开启。由于通孔设在固定板上而不影响外观，且门体关闭时通孔被密封气囊部压盖堵住而不影响密封，因此，通孔的尺寸可以根据需要设置为较大的尺寸，以达到良好的导通空气的作用，使得空气在门体开启时能够瞬间进入箱体，从而缩短门体开启时间，提升用户手感。有很强的实用性。
