本发明涉及一种安装在冰箱的门上的密封条。
背景技术
冰箱的门的密封条是在关闭门时与冰箱主体的储藏室的开口周缘部接触而密闭储藏室与门之间的间隙的部件。通过用密封条密闭储藏室和门之间的间隙，防止出现冰箱外部的热空气进入储藏室的现象和储藏室内部的冷空气向冰箱外部溢出的现象。

发明内容
本发明要解决的课题
但是，如专利文献1所示的使用磁体的密封条，由于是将磁体插通密封条的结构，因此为了使磁体保持笔直，密封条需要一定的厚度。因此存在无法使磁体变薄、无法使冰箱主体与门之间的间隔变窄、无法减小发生热泄漏的部位的面积的问题。另外，由于磁体材料的导热系数高，因此存在容易传导热而无法充分隔断冰箱外部的温度的问题。
本发明的目的在于提供一种能够使冰箱主体与门之间的间隔变窄并能隔断冰箱外部的温度的冰箱。
用于解决问题的手段
本发明的密封条是安装在冰箱门的包括四边的整周，在所述门处于关闭状态时密闭所述门和储藏室，其特征在于，
在剖视观察下，基端部分、密封片部分、袋部分以及平面板状部分一体形成，
所述基端部分安装在所述门上形成的槽中；
所述密封片部分从所述基端部分沿着所述门和所述储藏室之间延伸；
所述袋部分安装在所述基端部分，其中容纳使所述储藏室与外部气体绝热的空气；
所述平面板状部分为所述袋部分的一部分，并与所述储藏室接触，
整体含有磁性材料，所述平面板状部分被选择性地磁化。
根据本发明，一体形成的密封条的平面板状部分被选择性地磁化，并作为磁体发挥作用，因此不需要在密封条上另外添加磁体。因此，能够使平面板状部分变薄，所以能够使冰箱主体与门之间的间隔变窄。另外，由于不使用磁体，因此能够将密封条的导热系数抑制得较低。因此能够提供一种能使冰箱主体与门之间的间隔变窄且能隔断冰箱外部的温度的冰箱。
另外，本发明的密封条的特征在于，在一体挤压成型后，所述平面板状部分被选择性地磁化。
本发明的密封条能够通过一体挤压成型这样的简单的制作方法制作，能够省略在密封条中插入磁体的工序，因此成品率提高。另外，由于密封条的平面板状部分作为磁体使用，所以能够减少材料，降低成本。
另外，本发明的密封条的特征在于，所述平面板状部分的磁力为118±10g/m 2，硬度为60A～75A肖氏A硬度。
借助所述磁力，本发明的密封条可充分地靠近储藏室的开口边缘以密闭门和储藏室。另外，由于所述硬度，本发明的密封条能够提高储藏室和门的密闭力。
另外，本发明的密封条的特征在于，含有作为所述磁性材料的铁氧体粉末、氯乙烯以及热塑性弹性体。
本发明的密封条由作为磁性材料的铁氧体粉末、氯乙烯和热塑性弹性体形成。通过铁氧体粉末能够使密封条带磁性，通过氯乙烯和热塑性弹性体，能够使密封条软化而产生弹性。
另外，本发明的冰箱的特征在于，包括所述密封条，所述储藏室是冷藏室或冷冻室。
本发明的密封条能够适用于包括冷藏室或冷冻室的冰箱。
根据本发明，能够提供一种能够使冰箱主体与门之间的间隔变窄并能隔断冰箱外部的温度的冰箱。

具体实施方式
以下，参照附图说明用于实施本发明的各种实施方式。需要说明的是，以下说明的密封条403是用于将本公开的技术思想具体化的部件，只要没有特定的记载，本公开就不限于以下部件。考虑到对要点的说明或理解的容易性，为了方便，在不同的附图中，使用相同的附图标记。特别是，关于相同结构的相同作用效果，不会在每个实施方式或实施例中依次提及。为了明确说明，有时也夸张示出各附图所示的部件大小、位置关系等。
(冰箱的整体结构的说明)
图1是本发明的实施方式的冰箱的示意立体图。如图1所示，本发明的实施方式的冰箱101包括能够在其内部储藏食品等的冰箱主体103。冰箱101包括开闭冰箱主体103前方的开口的门105。
图2是本发明的实施方式的冰箱主体103的示意立体图。参照图2说明构成冰箱101的部件。
冰箱主体103除了前侧的开口以外，由配置有绝热材料的冰箱主体103的上表面部、下表面部、背面部、两个侧面部包围。在门105关闭时，冰箱主体103在位于这些上表面部、下表面部以及两个侧面部的开口周缘部201a～201d，与密封条403紧贴。
储藏室203设置有多个搁板，能够储藏大量食品等，因此能够有效地利用储藏室203的空间。此处，冰箱101有一扇门，储藏室203也是一个，各搁板的温度大致恒定。
(门和密封条的说明)
图3是本发明的实施方式的冰箱101的门105的示意立体图。图4是本发明的实施方式的冰箱101的门105的(a)拆下密封条403后的门外形部件401和(b) 密封条403的示意立体图。图5是沿图1的箭头A－A的俯视剖视图。参照图3至图5，对构成冰箱101的门105的密封条403进行说明。
使用图3说明门105的形状和功能。门105与储藏室203的开口侧的面部相对应，呈大致长方形状。门105的内表面也可以设置具有储藏功能的搁板。
门105具有一定的厚度，并具有隔热性，如后所述，通过利用密封条403隔断外部空气，由此冰箱101具备保温性。门105的外部设有把手，人能够打开或关闭门105。如图1所示，门105的外表面为平面，因此也可以安装显示装置等来监视箱内的状态。
使用图4对密封条403相对于门105的配置和拆装进行说明。门105能够分离为图4中(a)所示的门外形部件401和图4中(b)所示的密封条403。门外形部件401占据门105的外形和功能的大部分，以下称为门401。
冰箱主体103的开口周缘部201a～201d由涂装钢板形成，并设有与门105的内表面的外周紧贴的吸附部。密封条403配置在与该吸附部对应的位置。即，在门401的与该四边的吸附部对应的整周设置密封条403。
门401的整周开设有槽，如后所示，通过将基端部分601插入门401上所形成的槽中来安装密封条403。
使用图5对在门401上安装有密封条403的状态进行说明。图5是冰箱主体103处于被门401关闭的关闭状态下的俯视剖视图。在该关闭状态下，密封条403在门401的左右两侧，且配置在门401和冰箱主体103之间。
冰箱主体103和门401形成作为封闭空间的储藏室203，其内部通过密封条403隔断冰箱主体103的箱内的空气和门401外的空气来进行密封。在打开门401时，施加力拉动门401，直到能够解除密封条403的磁力。
至此，与储藏室203的数量相对应地设了一个门，但本发明并不局限于此，如果储藏室203为多个也可以设置多个门401。
(本发明的密封条的说明)
图6是本发明的实施方式的密封条403的剖视图。密封条403在剖视观察下，一体形成地包括基端部分601、密封片部分603、安装在基端部分601的袋部分605、作为袋部分605的一部分的平面板状部分607。
密封条403整体可以弹性变形。在门401关闭时，密封条403的袋部分605与冰箱主体103紧贴的部分容易压缩变形，并在门401打开、密封条403与冰箱主体103分离时复原。由此能够密闭储藏室203内部。
另外，由于空气的绝热性比密封条的材料高，因此能够利用容纳于袋部分605的空气将储藏室203与外部气体绝热。
在门401的整周开设有圆形状剖面的槽。安装在门上形成的槽中的基端部分601在紧密接触地嵌入该槽的躯干部的顶端具有挡块，所述挡块具有箭头形的剖面。由于基端部分601弹性变形，在基端部分601被压缩而嵌入槽之后，通过挡块复原而安装密封条403。
基端部分601能够利用紧密接触地嵌入槽的躯干部，来防止空气从门401与密封条403之间流通。另外，通过具有所述箭头形的剖面的挡块，在打开门401时，冰箱主体103与密封条403的紧贴力不会超过密封条403与门401的连接力，因此密封条403不会脱落。
另外，密封条403包括从基端部分601沿着门401和储藏室203之间延伸的密封片部分603。密封条403在门401关闭的状态下，该密封片部分603弹性变形，并与门401的槽的周围的平坦部分紧贴，由此进一步密封门401和密封条403。此处示出一个密封片部分603，但密封片部分603也可以是多个，也可以从袋部分605延伸。
平面板状部分607由于其厚度而难以弹性变形。假设将通常的袋部分605的厚度设为约0.5mm，则平面板状部分607的厚度约为其2倍，为0.8mm至1.5mm，优选为约1mm。平面板状部分与储藏室203的开口周缘部201a～201d面接触。因此，平面板状部分607在关闭了门401时，能够以较大的面积与开口周缘部201a～201d紧贴。
密封条403整体含有磁性材料，平面板状部分607被选择性地磁化。平面板状部分607被选择性地磁化，并作为磁体发挥作用，因此不需要在一体形成的密封条403添加磁体。另外，平面板状部分607由于其厚度而具备足够的磁性。
由于平面板状部分607的厚度约为1mm，因此与现有的使用包括磁体的密封条的冰箱相比，袋部分605的厚度、即冰箱主体103与门401之间的间隔能够缩小约2.5mm。因此能够提供能隔断冰箱101外部的温度的冰箱101。
另外，本发明的密封条403是在将密封条材料一体挤压成型后，选择性地磁化平面板状部分607而成的。密封条403一体挤压成型，能够以简单的制作方法制作，能够省略在密封条中插入磁体的工序，因此成品率提高。另外，由于平面板状部分607作为磁体使用，因此能够减少材料，降低成本。
另外，本发明的密封条403中，优选地，所述平面板状部分607的磁力为118±10g/m 2，硬度为60A～75A肖氏A硬度。借助这样的磁力，能够充分地靠近储藏室 203的开口周缘部201a～201d，以密封门401和储藏室203。另外，通过这样的硬度，能够提高门401和储藏室203的密闭力。
本发明的密封条403由作为磁性材料的铁氧体粉末、氯乙烯和热塑性弹性体形成。铁氧体粉末的重量百分比为80～90％，优选为85％，氯乙烯和热塑性弹性体的重量百分比为10～20％，优选为15％。通过铁氧体粉末能够使密封条403带有磁性，通过氯乙烯和热塑性弹性体能够使密封条403软化，产生弹性。
热塑性弹性体可以采用聚氨酯系、烯烃系、苯乙烯系、聚酰胺系、聚酯系、丙烯酸系等。这些材质可以考虑耐气候性、耐化学性等来选择。
本发明的密封条403能够用于冰箱101的门401，冰箱101的储藏室203可以是冷藏室或冷冻室。
根据本发明，提供不另需磁体的密封条403。因此，能够使冰箱主体103与门401之间的间隔比现有的冰箱窄。因此能够提供能够隔断冰箱101外部的温度的冰箱101。
另外，本发明的密封条403能够以简单的制作方法制作，能够省略在密封条中插入磁体的工序，因此成品率提高。另外，由于平面板状部分607作为磁体使用，因此能够减少材料，降低成本。
本发明的密封条403充分地靠近储藏室203的开口周缘部201a～201d，能够密闭门401和储藏室203。另外，通过适度的硬度，能够提高储藏室203和门401的密闭力。
根据本发明，能够利用铁氧体粉末使密封条403带有磁性，能够利用氯乙烯和热塑性弹性体使密封条403软化而产生弹性。
上述实施方式的说明在所有方面均为示例，并不局限于此。对于本领域技术人员而言，能够适当进行变形和变更。本发明的范围不由上述实施方式示出，而是由权利要求书示出。此外，本发明的范围包括与权利要求书同等范围内的实施方式的变更。
