目前，通常采用的门封截面结构如图1所示，参见图1，门封包括磁条囊01、安装脚02以及气囊03，气囊03包括与冰箱门胆相对的纵向壁031和横向壁032，气囊03内部被筋条04分隔为两个独立的气室，即第一气室051和第二气室052。参见图2，磁条囊01中插设有磁条011，安装脚02配合插设于冰箱门胆06上的安装槽061内，以实现门封在冰箱门胆06上的固定，冰箱箱胆07上设有侧板08，磁条011能够借助磁力吸合在侧板08上，使门封封住冰箱箱胆07与冰箱门胆06之间的间隙，阻隔冰箱内、外的热量交换，降低冰箱的能耗。
冰箱门体关闭时，冰箱门围绕着门体铰链中心轴旋转，在磁条011吸力的作用下，磁条囊01一侧的门封首先与侧板08接触并吸合在侧板08上，此时继续旋转关闭冰箱门，冰箱门胆06通过纵向壁031和横向壁032挤压第一气室051，继而推动磁条011在侧板08上向前移动。但由于第一气室051中的气体具有可压缩性，导致气囊03对磁条011的支撑力不足，很难推动磁条011随着门体的关闭在侧板08上继续向前移动。当冰箱门完全闭合后，此时的门封可能
为图2所示的状态，即气囊03在图2所示a位置处产生内陷坍塌，同时在图2所示b位置因受挤压而产生外凸，导致门封与侧板08的搭边距(即门体完全关闭后，门封与侧板08吸合重叠部分的长度L，如图2所示)偏小，进而影响门封的保温效果，增加冰箱整体耗电量，严重时还会使门封产生变形，卷边(即门封外侧翘起)等问题，使门封与冰箱门胆06配合处产生缝隙，导致冰箱漏冷、能耗上升，并在配合缝隙处产生凝露现象。
为了给磁条囊01提供较大的支撑力，中国专利CN204329443U通过设置副气囊来增大门封的搭边距。参见图3，副气囊09设置于磁条囊01的右侧，副气囊09的上端面高于磁条囊01的上端面，磁条囊01和副气囊09的下方设有主气囊010，在磁条囊01一侧门封吸合在侧板上，并继续关闭冰箱门的过程中，副气囊09高出磁条囊01的部分受冰箱箱胆的挤压而压缩副气囊09内部的气体，使副气囊09积蓄一定的弹性势能，且内部气体的可压缩性降低，此时若冰箱门胆推动纵向壁031，副气囊09可支撑磁条在侧板上向前移动，在一定程度上增大了门封搭边距。但是，由于主气囊010和副气囊09内部的支撑力不足，因此主气囊010和副气囊09对磁条仍不能进行有效的支撑，导致门封的搭边距偏小，进而影响了门封的保温效果。
发明内容
本发明的实施例提供一种冰箱用门封及冰箱，能够提高门封气囊内部支撑力，从而增大门封搭边距，降低门封变形、卷边几率。
为达到上述目的，本发明的实施例提供了一种冰箱用门封，包括：磁条囊，所述磁条囊用于放置磁条；安装脚，所述安装脚用于将所述门封安装到冰箱门胆上；气囊，所述气囊连接于所述磁条囊与所述安装脚之间，所述气囊包括与冰箱门胆相对的纵向壁和横向壁，所述气囊气腔内设有横向筋条和纵向筋条，所述横向筋条一端与所述磁条囊的外壁连接，另一端与所述纵向壁连接，所述纵向筋条的第一端与所述横向筋条或磁条囊连接，所述纵向筋条的第二端
与所述横向壁连接。
本发明实施例还提供了一种冰箱，包括冰箱门，所述冰箱门的内侧设有冰箱门胆，所述冰箱门胆的中部凸起形成台阶面结构，所述门封围绕所述冰箱门胆的凸起设置，所述门封为上述技术方案中的门封，所述台阶面的水平面上设有安装槽，所述门封的安装脚配合插设于所述安装槽内，所述门封的气囊的横向壁与所述台阶面的水平面相贴合，所述气囊的纵向壁与所述台阶面的竖直面相贴合，所述门封的磁条囊内设有磁条。
本发明实施例提供的一种冰箱用门封及冰箱，由于气囊的气腔内设有横向筋条和纵向筋条，因此可对气囊内部形成有效支撑。具体地，由于横向筋条一端与磁条囊的外壁连接，另一端与纵向壁连接，且纵向壁与冰箱门胆相对设置，因此，当磁条囊吸合在冰箱箱体侧板上，并继续关闭冰箱门的过程中，冰箱门胆可与纵向壁贴合，并给纵向壁施加一个关门方向的推力，纵向壁可将推力通过横向筋条传递给磁条囊，从而给磁条囊提供了一个较稳固的横向支撑力，防止气囊在推动磁条囊滑动的过程中发生横向坍塌；同时由于气囊的气腔内设有纵向筋条，纵向筋条的第一端与横向筋条或磁条囊连接，纵向筋条的第二端与横向壁连接，且横向壁与冰箱门胆相对设置，因此，当磁条囊吸合在侧板上，并继续关闭冰箱门的过程中，冰箱门胆可与冰箱门胆相贴合，并给横向壁施加一个关门方向的推力，横向壁将此推力传递给磁条囊或横向筋条，从而给磁条囊或横向筋条提供了一个较稳固的纵向支撑力，防止了气囊在推动磁条囊滑动的过程中发生纵向坍塌。由此，通过横向筋条和纵向筋条共同作用，增大了门封气囊的内部支撑力，防止气囊受挤压外凸或内陷坍塌，从而增大了门封搭边距，降低了门封变形、卷边几率。

冰箱通常包括冰箱箱体和冰箱门体，冰箱门胆设置于冰箱门体的内侧，冰箱箱胆设置于冰箱箱体的内侧，冰箱箱体和冰箱门体通过两个或两个以上的铰链连接，两个或者两个以上铰链的铰链轴沿
同一轴线设置，使冰箱门体可以围绕该同轴线旋转，以实现冰箱门体的开合。当冰箱门体闭合时，冰箱门体与冰箱箱体闭合面之间设有门封，以封堵冰箱门体与冰箱箱体之间的间隙。通常，门封固定于冰箱门体上的门胆上，门封靠近冰箱门体的一端设有磁条，同时冰箱箱体的闭合面上设有侧板，侧板采用金属材料制作，磁条通过磁力吸合在侧板上，以密封冰箱门体与冰箱箱体之间的间隙，阻隔冰箱内、外的热量交换，降低冰箱的能耗。
参见图4，图4为本发明实施例冰箱用门封的一个具体实施例，本实施例的冰箱用门封包括：磁条囊1，所述磁条囊1用于放置磁条；安装脚2，所述安装脚2用于将所述门封安装到冰箱门胆上；气囊3，所述气囊3连接于所述磁条囊1与所述安装脚2之间，所述气囊3包括与冰箱门胆相对的纵向壁31和横向壁32，所述气囊的气腔5内设有横向筋条41和纵向筋条42，所述横向筋条41一端与所述磁条囊1的外壁连接，另一端与所述纵向壁31连接，所述纵向筋条42的第一端与所述横向筋条41连接，所述纵向筋条42的第二端与所述横向壁32连接。
本发明实施例提供的一种冰箱用门封，由于气囊3的气腔5内设有横向筋条41和纵向筋条42，因此可对气囊3内部形成有效支撑。具体地，由于横向筋条41一端与磁条囊1的外壁连接，另一端与纵向壁31连接，且纵向壁31与冰箱门胆相对设置，因此，当磁条囊1吸合在冰箱箱体侧板上，并继续关闭冰箱门的过程中，冰箱门胆可与纵向壁31贴合，并给纵向壁31施加一个关门方向的推力，纵向壁31可将推力通过横向筋条41传递给磁条囊1，从而给磁条囊1提供了一个较稳固的横向支撑力，防止气囊3在推动磁条囊1滑动的过程中发生横向坍塌；同时由于气囊3的气腔5内设有纵向筋条42，纵向筋条42的第一端与横向筋条41连接，纵向筋条42的第二端与横向壁32连接，且横向壁32与冰箱门胆相对设置，因此，当磁条囊1吸合在侧板上，并继续关闭冰箱门的过程中，冰箱门胆可给横向壁32施加一个关门方向的推力，横向壁32将此推力
传递给磁条囊1或横向筋条41，从而给磁条囊1或横向筋条41提供了一个较稳固的纵向支撑力，防止了气囊3在推动磁条囊1滑动的过程中发生纵向坍塌。由此，通过横向筋条41和纵向筋条42共同作用，增大了门封气囊3的内部支撑力，防止气囊3受挤压外凸或内陷坍塌，从而增大了门封搭边距，降低了门封变形、卷边几率。
在上述实施例中，纵向筋条42的第一端除了可以与横向筋条41连接之外，还可以与磁条囊1的外壁连接。当纵向筋条42的第一端与横向筋条41连接时，在磁条囊1吸合在侧板上，并继续关闭冰箱门的过程中，由于横向筋条41一端与磁条囊1的外壁连接，因此纵向筋条42可以通过横向筋条41给磁条囊1传递一个纵向支撑力，从而与横向筋条41共同作用，增大气囊3对磁条的支撑作用力，进而增大门缝搭边距，此外，纵向筋条42还可以对横向筋条41起到固定支撑作用，防止横向筋条41因受力过大而产生弯曲变形，保证了横向筋条42对气囊3的有效支撑，由于横向筋条41上中部位置最易变形，因此可进一步优选纵向筋条42的第一端连接于横向筋条41的中部位置；当纵向筋条42与磁条囊1的外壁连接时，纵向筋条42直接给磁条囊1提供一个纵向支撑力，支撑力更稳固，但此时横向筋条41由于无支撑而在受力过大时容易产生弯曲变形，从而影响了横向筋条41对磁条囊1的横向支撑作用。
将上述门封固定于冰箱门体的门胆上，当冰箱门体完全关闭时，门封、冰箱门胆、冰箱箱胆、侧板之间的装配结构如图5所示，参见图5，安装脚2配合插设于冰箱门胆6上的安装槽61内，以实现门封在冰箱门胆6上的固定，冰箱箱胆7上设有侧板8，磁条11能够借助磁力吸合在侧板8上，使门封封住冰箱箱胆7与冰箱门胆6之间的间隙，阻隔冰箱内、外的热量交换，降低冰箱的能耗。
需要说明的是，为了方便描述，当门封安装于冰箱门胆上时，定义门封靠近冰箱箱胆的一侧为上侧，与上侧相对，且靠近冰箱门胆的一侧为下侧。
为了增大气囊3的支撑力，增加门封的搭边距，降低门封变形、
卷边几率，如图4所示，优选纵向筋条42垂直于横向壁32设置或纵向筋条42的第一端相对于第二端向靠近磁条囊1的方向倾斜设置，纵向筋条42与横向壁32的夹角为α，α≤90°，当以如图6中箭头方向关闭冰箱门的过程中，纵向筋条42可提供一个斜向左上方的支持力F1，并优选F1的方向与冰箱门体关闭方向一致，此时F1能够在垂直于磁条囊1的方向上提供一个分力，该分力对门封起到一定的支撑作用，防止冰箱门体关闭过程中门封因受挤压而变形或气囊3内陷坍塌。又优选纵向筋条42与横向筋条41的夹角为β，45°≤β≤90°，当以如图6中箭头方向关闭冰箱门的过程中，横向筋条41可对磁条囊1提供一个支撑力F2，并优选F2的方向与冰箱门体关闭方向一致，使支撑力F2的方向为如图6所示斜向左上方，以在平行于磁条囊1的方向上提供一个分力来推动磁条11在侧板8上继续移动直至冰箱门体完全闭合，解决门封搭边距偏小的问题，同时在垂直于磁条囊1的方向产生一个分力，以增强气囊3内部支撑力。
其中，纵向筋条42可以是直线型，也可以整体呈曲线型。当采用上述第二种方案时，即纵向筋条42整体呈曲线，在关闭冰箱门体的过程中，冰箱门胆6挤压气囊3的横向壁32，给纵向筋条42靠近横向壁32的一端施加一个作用力，在此作用力下，纵向筋条42容易发生弯曲变形，使纵向筋条42对横向筋条41或磁条囊1的支撑不足，进而导致纵向筋条42对磁条11的支撑不足，严重时容易使气囊3受挤压外凸或者内陷坍塌，从而减小了门封搭边距。因此，为了避免上述问题，优选纵向筋条42为直线型，作用力的方向与纵向筋条42所在的直线方向相同，能够有效支撑磁条11在侧板8上向前移动，增大了门封搭边距。
针对1号冰箱、2号冰箱和3号冰箱，分别采用现有技术(如图1所示)和本发明实施例(如图4)的门封密封冰箱门体与冰箱箱体之间的间隙，然后分别测量冰箱上门的顶部、上部、中部、下部，下门的上部、中部、下部的搭边距值，得到两组对比值，并将
两组对比值记录在表1中。从表1的测量数据可以看出：在理论搭边距相同的条件下，即磁条囊1与气囊3的尺寸及相对位置均无变动，本发明实施例的门封搭边距实测值明显大于现有技术门封搭边距实测值。这说明在实际装配及使用过程中，横向筋条41和纵向筋条42可有效增强气囊3内部支撑力，增大门封搭边距，降低门封卷边几率。而现有技术门封气囊03内部支撑性不足，在关闭冰箱门体的过程中气囊03难以有效推动磁条011在侧板08上向前移动，且气囊03受挤压后容易产生外凸、内陷坍塌等问题，从而导致门封搭边距偏低，严重时容易产生门封变形、卷边等问题，影响门封的密封保温效果。
表1
需要说明的是，在本发明实施例中，仅以上述表1为例进行说明，上述表1并不对本发明实施例构成限定。
其中，横向筋条41与磁条囊1连接的一端可以呈弯曲状，如图4所示，横向筋条41的弯曲部分通过支撑点P2与磁条囊1相连并对磁条囊1起着向上的支撑作用，新增的支撑点P2与原有的支撑点
P1协同作用，增强了气囊3内部对磁条囊1的支撑强度，防止关门过程中出现磁条囊1绕单一支撑点旋转而产生装配问题，如门封搭边距偏小、门封卷边或在门封与侧板8之间产生离缝，而且，由于实际生产制造过程中箱门间距的控制并不理想，冰箱箱体、冰箱门体等与门封有装配关系的零部件稍有变形都会导致箱门间距与理论值的偏差，甚至是同一台冰箱不同位置的箱门间距都会有所不同，因此，弯曲状结构设计可赋予气囊3一定的弹性，使气囊3能够通过弯曲结构的伸缩变形来适应实际生产过程中在一定范围内偏差波动的箱门间距，从而有效解决了门封卷边或离缝等问题。
可选地，横向筋条41与磁条囊1连接的一端还可以为直线状，如图7所示，此时横向筋条41与磁条囊1的右侧壁或右下角顶点连接，通过横向筋条41的推力F2在平行于磁条囊1方向的分力来推动磁条11在侧板8上移动，通过F2在垂直于磁条囊1方向的分力在支撑点P2处对磁条囊1起着向上的支撑作用，并与原有的支撑点P1协同作用，防止关闭冰箱门体时磁条囊1绕单一支撑点转动而产生装配问题。此可选方案适用于气囊3的高度较低、气囊3内部设计空间较小的门封截面类型，以兼顾门封挤出、焊接工艺性，避免门封黏连。
具体地，如图4所示，横向筋条41和纵向筋条42将气囊3的气腔5分割为第一气室51、第二气室52和第三气室53。第一气室51与磁条囊1平齐且位于横向筋条41的上方，在磁条囊1吸合在侧板上，并继续关闭冰箱门的过程中，冰箱门胆可挤压第一气室51，使第一气室51给磁条囊1提供一个支撑力，该支撑力可推动磁条11在侧板8上向前移动，从而增大门封的搭边距；第二气室52位于第一气室51的下方，在磁条囊1吸合在侧板上，并继续关闭冰箱门的过程中，冰箱门胆可挤压第二气室52，使第二气室52给纵向筋条42提供一个支撑力，提高纵向筋条42对横向筋条41或磁条囊1的支撑作用，第三气室53与第二气室52平齐，纵向筋条42位于第二气室52与第三气室53之间，第三气室53的一部分位于磁条囊1的
下方，另一部分位于第一气室51的下方。由于空气的热传导系数(约0.0223W/m.K)较低，故门封通常是利用气囊内部的空气来抑制或降低冰箱内、外的热量交换，因此可进一步通过将气囊内部分隔为多个气室来增强气囊的密封隔热性能，多个气室相互独立，相邻两气室之间的气体不对流，可大幅降低两者之间的热量交换，且被分隔的气腔数量越多，气囊的密封隔热性越好。与如图1所示现有技术实施例相比，采用本发明实施例的冰箱用门封密封冰箱门体与箱体之间的间隙，横向筋条和纵向筋条将气囊的气腔分割为三个彼此独立的气室，相比于现有技术的两个气室，气室的数量增加，大大降低了热交换幅度，有效抑制了冰箱内、外的热量交换。当然，本领域技术人员也可以再增加更多的气室的分割。
其中，如图3所示的现有技术实施例，当如图3所示门封应用于冰箱中时，若箱门间距低于理论值，此时由于副气囊09高出磁条囊01，一旦磁条吸合在箱体侧板上，副气囊09将会与侧板08产生相互挤压作用，从而增大了两者之间的摩擦力，不利于关门时磁条囊01在侧板08上向前滑移，从而降低门封搭边距，导致门封卷边，且积蓄的弹性势能还会带来其他装配工艺问题，如门体反弹，生产制造、维修返修成本上升等，因此此方案门封不适用于箱门间距低于理论值的产品，从而降低了门封的普适性。因此，为了避免如图3所示现有技术中副气囊09的上端面高于磁条囊01上端面所产生的不良影响，优选第一气室51的上端面与磁条囊1的上端面平齐，由此即使箱门间距低于理论值，磁条11在箱体侧板8上吸合并向前滑移的过程中，气囊3将不会与侧板8产生相互挤压，避免了出现气囊3与侧板摩擦力增大、冰箱门体反弹等问题，从而增大了门封的搭边距，提高了门封的普适性。
由于冰箱箱体、冰箱门体在制作过程中容易出现一定程度的变形，为弥补此变形量，门封与冰箱箱胆7、冰箱门胆6四周贴合部分通常会留有一定的配合间隙，冰箱内部的冷空气可直接通过此间隙向外泄露。因此，为了避免上述问题，优选在纵向壁31和横向壁
32的连接处的外表面设置第一翅边33，可阻隔箱内冷空气从冰箱门胆6与门封配合间隙处向外泄露，且第一翅边33与冰箱门胆6过盈配合可以形成两个等效气囊，可进一步降低冰箱门胆6与门封配合处的热交换效率。此结构简单，制作成本低。
同理，如图5所示，优选在第一气室51远离磁条囊1的一侧上方连接辅助气囊9，其形状与冰箱箱胆7、冰箱门胆6配合处结构相吻合，可有效封堵冰箱箱胆7与冰箱门胆6之间的配合间隙。结构简单，且可实现配合间隙的有效密封。
进一步地，为了增强辅助气囊9的密封隔热性能，辅助气囊9的气腔内可以包括多个彼此独立的气室，例如可以包括如图5所示两个彼此独立的气室，从而降低了冰箱内冷空气与外界热空气的能量交换效率。
实际生产过程中为便于安装脚2在安装槽61内的装配，同时为避免制造误差导致安装困难，通常将安装槽61的深度设置得比安装脚2的高度大，以方便安装操作。如图5所示，门封安装脚2的高度比安装槽61的深度小，装配后安装脚2的底部与安装槽61的底部之间存在间隙，冰箱内的冷气可以从此间隙处泄露，增大了冰箱的耗能量。为避免上述问题，安装脚2的底部可以设置弯曲状的第二翅边34，当安装脚2插设于安装槽61时，第二翅边34的底部与安装槽61的底部贴合，第二翅边34的末端翘起，能够适应不同高度的间隙，具有良好的变形能力和适应性，且在与安装槽61过盈配合时能顺利插入并与安装槽61的底部贴合，不会因弯折变形而产生缝隙，可有效防止箱内冷空气沿安装脚2底部与安装槽61底部之间的间隙向外泄露，同时，第二翅边34将安装槽61底部间隙一分为二形成左右两个等效气囊，降低了内外部空气对流换热效率，提高了门封的密封隔热性能。此结构简单，制造成本低。
针对1号冰箱、2号冰箱和3号冰箱，分别采用现有技术(如图1所示)和本发明实施例(如图4)的门封密封冰箱门体与冰箱箱体之间的间隙，然后分别测量冰箱的上门门封、下门门封、回气
管以及后背板等位置的凝露状况(外界温度环境为32℃时，测试湿度为85％)、以及耗电量数据(外界温度环境为25℃)，得到两组对比值，并将两组对比值记录在表2、图8中。从表2和图8的数据可知，采用本发明实施例的冰箱用门封，冰箱整体耗电量下降达2％，凝露问题也得到明显改善。对比图2和图5的连接结构示意图可知，气囊3内部的横向筋条和纵向筋条结构不仅有效提高了门封内部支撑力，增加了门封搭边距，降低了门封变形、卷边几率，且通过纵横筋条将气囊3分隔为三个独立的气室，可有效增强其密封隔热性能，降低冰箱内、外的热量交换。同时，通过气囊3内侧凸出的辅助气囊9封堵冰箱箱胆7与冰箱门胆6配合间隙，通过内侧下方第一翅边33阻隔冰箱门胆6与门封配合处的冷气外泄，通过安装脚2底部的第二翅边34与安装槽61过盈配合防止冷空气沿安装脚2底部的间隙向外泄露，从多个角度降低热交换效率、提高密封效果，有效改善凝露状况，降低冰箱整体耗电量。
表2
需要说明的是，在本发明实施例中，仅以上述表2为例进行说明，上述表2并不对本发明实施例构成限定。
进一步地，为了增加门封的普适性，在不改变门封主体外轮廓尺寸的基础上，可对气囊3内部结构进行调整并适当增加翅边结构的数量，且辅助气囊9的形状及大小可根据冰箱箱胆7与冰箱门胆6配合处的结构进行适应性调整，以增强门封的普适性。例如，将本发明实施例冰箱用门封应用于对开门冰箱上，装配结构如图9所示，采用第一门封100密封冷藏门体与冰箱箱体之间的间隙，同时采用第二门封200密封冷冻门体与冰箱箱体之间的间隙。对开门冰箱与单门冰箱、两门冰箱或者三门冰箱的主要差别体现在冷藏门和冷冻门相对处为竖中梁300，竖中梁300用以连接冷藏箱胆401与冷冻箱胆402，且冷藏门胆501和冷冻门胆502四周由于胆筋的支撑而产生凸起，从而改变了冷藏箱胆401和冷藏门胆501之间a位置的配合结构，以及冷冻箱胆402和冷冻门胆502之间b位置的配合结构，分别采用第一门封100的第一辅助气囊101和第二门封200的第二辅助气囊201封堵此配合结构的间隙，并调整第一辅助气囊101和第二辅助气囊201的形状及大小以适应此间隙，从而使本发明的冰箱用门封能够有效密封对开门冰箱门体与箱体之间的间隙，增强了门封的普适性。因此，本发明实施例的冰箱用门封不仅适用于单门、两门、三门冰箱，还可推广应用于对开门、多门冰箱，具有广阔的应用前景。
本发明实施例还提供了一种冰箱，包括冰箱门，所述冰箱门的内侧设有冰箱门胆6，所述冰箱门胆6具有凸起结构，所述门封围绕所述凸起结构设置，所述门封为上述任一实施例所述的门封，所述冰箱门胆6位于所述凸起结构周围的表面上设有安装槽61，所述门封的安装脚2配合插设于所述安装槽61内，所述门封的气囊3的
横向壁32与所述冰箱门胆6位于所述凸起结构周围的表面相对，当门封的磁条囊1吸合在冰箱箱体侧板上，并继续关闭冰箱门的过程中，所述门封的气囊3的横向壁32能够与所述冰箱门胆6位于所述凸起结构周围的表面相贴合，所述气囊3的纵向壁31与所述凸起结构的侧壁相对，当门封的磁条囊1吸合在冰箱箱体侧板上，并继续关闭冰箱门的过程中，所述气囊3的纵向壁31能够与所述凸起结构的侧壁相贴合，所述门封的磁条囊1内设有磁条11。
由于在本实施例的冰箱中使用的门封与上述冰箱用门封的各实施例中提供的门封相同，因此二者能够解决相同的技术问题，并达到相同的预期效果。
关于本发明实施例的冰箱的其他构成等已为本领域的技术人员所熟知，在此不再详细说明。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
