下面详细描述本发明的实施例, 所述实施例的示例在附图中示出, 其中自始至终相 同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附 图描述的实施例是示例性的, 仅用于解释本发明, 而不能理解为对本发明的限制。

本申请是基于发明人对下面事实的发现: 在釆用吸塑的方法制作门胆时, 且水箱的 门胆的吸塑高度超过一定高度, 容易在门胆上出现冷斑痕。特别是在制作 40mm以上的 水箱的门胆时容易出现冷斑痕。 发明人此前釆用了多种手段, 例如减小门胆的厚度、 改 变所使用的材料等均未能解决该问题。 此外, 在冷斑痕问题在业界存在已久, 到目前为 止也未有很好解决该问题的技术方案出现。
为了消除冷斑痕, 即在釆用吸塑方式制作水箱的门胆时, 为了提高水箱的品质, 避 免在门胆上出现冷斑痕, 目前通常只能釆用降低门胆的厚度, 才能避免在门胆上形成冷 斑痕,以提升生产门胆时门胆的合格率。但这种降低水箱的门胆的厚度的方式又无法满 足人们对水箱门胆厚度的需求, 例如, 大水箱需要的门胆的厚度较大。
本发明旨在提出一种水箱的门胆结构,这种结构的提出即能避免冷斑痕的产生又能 保证用户对水箱厚度的需求。 更具体而言, 本申请是对现有的用于水箱的较厚的门胆的 结构进行改进, 以避免在釆用吸塑的方法制造门胆时产生冷斑痕。 发明人发现, 在生产 较厚的水箱门胆时, 如果在容易产生冷斑痕区域增加至少一道凹筋, 则意外地发现可以 避免冷斑痕出现。
下面, 发明人将参照附图对本发明的用于水箱的门胆进行详细的描述。 其中, 图 3 显示了根据本发明的一个实施例的用于水箱的门胆的平面示意图,图 4显示了图 3中所 示的用于水箱的门胆的左视图。
如图 3-5所示, 根据本发明的实施例的用于水箱的门胆可以包括: 门胆本体 10以及门
胆周边部 20。
具体而言, 门胆周边部 20从门胆本体 10的周边向外延伸, 如图 11所示, 门胆周边 20 方便与水箱的箱门 80的壳体 81构造成水箱的箱门 80。
如图 4所示, 门胆本体 10沿着纵向的最大厚度大于 40mm。但门胆本体 10的厚度一般 不超过 80mm。
门胆本体 10的两个竖向(参见 3、 图 4 )侧面中的至少一个上形成有至少一条凹筋 11 , 且凹筋 11朝向门胆本体 10的内部凸出。 换言之, 如图 3、 4中所示, 在门胆本体 10的两 个竖向侧面 101中的至少一个上形成有至少一个朝向门胆 10内部突出的凹筋 11 , 凹筋 11 在门胆本体 10的外面呈现为凹部。
才艮据本发明实施例的用于水箱的门胆,如图 4所示,在门胆本体 10的两个竖向侧面 101 中的至少一个上形成有至少一条凹筋 11 , 可以避免在釆用吸塑方法生产门胆时由于门胆本 体 10沿着纵向的厚度过大, 例如厚度超过 40mm, 而使门胆上产生冷斑痕。 提高了生产水 箱门胆的产品合格率, 并提高了生产效率。
如图 3、 4所示, 根据本发明的一个实施例, 每个竖向侧面 101上形成有多条彼此间隔 设置的凹筋 11 , 且凹筋 11大体上沿着竖直方向延伸。 由此, 可以增加形成在竖向侧面 101 上凹筋 11的数量, 进一步提高胆在制作过程中, 其自身防止冷斑痕产生的能力。 根据本发 明的一个实施例, 每个竖向侧面 101上形成有两条彼此间隔设置的凹筋 11 , 且凹筋 11大体 上沿着竖直方向延伸。
如图 6所示, 才艮据本发明的一些实施例, 每个竖向侧面 101上形成有多条凹筋 11 , 且 每个凹筋 11间断地沿竖直方向延伸。 由此, 多条凹筋 11中的每个凹筋 11实际上是由多个 小凹筋组成, 多个小凹筋的数量多, 进一步提高门胆在制造过程中, 其自身防止冷斑痕产 生的能力。
如图 3、 图 4所示, 根据本发明一个示例, 凹筋 11构造成适于门胆本体 10底面 102的 形状。 由此, 在釆用吸塑方法制造门胆时, 可以使得材料从底部顺应所述凹筋 11而逐渐成 形门胆本体的侧面, 由此使得使门胆本体 10 内的材料分布更加均匀, 避免门胆本体 10的 厚度不均匀的现象的发生, 并消除冷斑痕的出现。
根据本发明的一些示例, 如图 3、 4所示, 门胆本体 10的底面 102与侧面和门胆本体 10的侧面与门胆周边部 20以圆弧过渡连接, 例如, 门胆本体 10的侧面可以包括竖向侧面 101和横向侧面。 门胆本体 10的底面 102与侧面或者门胆本体 10的侧面与门胆周边部 20 以圆弧过渡连接。 由此, 可以避免在釆用吸塑方法制造用于水箱的门胆时, 在门胆本体 10 的底面 102与侧面和门胆本体 10的侧面与门胆周边部 20的过渡部附近的材料的厚度不均 匀或出现冷斑痕。
优选地, 圆弧的半径大于 20mm。 由此, 可以进一步降低出现材料的厚度不均勾和出现 冷斑痕的概率。
下面将参照图 11来描述才艮据本发明的一个实施例的水箱,其中图 11示出了水箱的侧面 剖开的立体示意图。 如图 8中所示, 该水箱可以包括: 箱体 70和门体 80, 箱体 70中限定
有制冷间室 71。 门体 80用于打开和关闭制冷间室 71 , 其中门体 80上设置有根据本发明上 述实施例所述的门胆。 由此, 根据本发明的水箱由于门胆消除了冷斑痕, 从而外形更美观。
才艮据本发明实施例的水箱, 在箱门的门胆本体 10的两个竖向侧面 101中的至少一个上 形成有至少一条凹筋 11 ,可以避免在釆用吸塑方法生产门胆时由于门胆本体 10沿着纵向的 厚度过大, 例如厚度超过 40mm, 而使门胆上产生冷斑痕。 提高了生产水箱门胆的产品合格 率, 提高了生产效率。
下面将参照图 7-10来描述根据本发明的一个实施例的用于水箱的门胆的制造方法。 在 本发明中, 该门胆包括: 门胆本体 10以及门胆周边部 20, 门胆周边部 20从门胆本体 10的 周边向外延伸, 其中门胆本体 10沿着纵向 (参见图 4 ) 的最大厚度大于 40mm。 如图 12所 示, 所述方法包括如下步骤:
( 1 )提供阳模 30, 阳模 30可穿过下边框固定件 40并且阳模 30的外表面构造成适于 形成水箱的述门胆的内表面, 且用于成形门胆的竖向侧面 101的阳模 30的侧面 301的至少 一个上形成有至少一个凹槽 31。 凹槽 31的形状和大小与凹筋 11相匹配。
( 2 )将板材 100吸附在上边框固定件 50上。 例如, 可以在上边框固定件 50上开设多 个真空孔(未示出)以用来吸附板材 100。 该板材 100即为制作用于水箱的门胆的材料。 例 如可以为塑料。
( 3 )将所述上边框固定件 50相对于下边框固定件 40运动(参见图 8-9 ), 以对板材进 行吸塑, 以形成门胆(参见图 10 , 为最终形成的门胆 )。
由此, 通过在阳模 30上形成凹槽 31 , 可以在对板材 100的吸塑过程中让板材 100通过 凹槽 31 , 从而使得在成形的过程中通过凹槽 31的预变形而消除冷斑痕, 特别是消除由于门 胆本体 10沿着纵向的厚度过大、 特别是在最大厚度大于 40mm时、 而经常容易出现在门胆 上的冷斑痕。
在本发明中, 上边框固定件 50吸附板材 100的表面上形成有多个吸附口 (未示出), 从而方便通过上边框固定件 50容易地吸附和释放该板材 100。
如图 7 所示, 根据本发明的实施例的用于水箱的门胆的制造方法, 进一步包括: 在提 供阳模 30步骤之前对阳模进行预加热的步骤, 例如, 可以在阳模 30上方设置加热板 90, 对阳模进行预加热, 以将阳模 30加热到 80-100摄氏度。 此温度范围可以使板材 100软化, 使板材 100延展性增强,便于板材 100形成门胆。在阳膜 30的温度上升到 80-100摄氏度后, 移开加热板 90(参见图 8)。
如图 9-10所示, 根据本发明的一些实施例, 阳模 30中构造有冷却通路(未示出), 用 于在成形门胆之后在所述冷却通路中通入冷却液体以对该门胆进行冷却。
根据本发明的一些示例, 用于成形阳模 30的侧面 301上形成有多个彼此间隔设置的凹 槽 31 , 且凹槽 31构造成大致平行于阳模 30的上表面。 由此, 可以在门胆上形成与凹槽 31 对应的多个彼此间隔设置的凹筋 11。
根据本发明的一个具体示例, 每个凹槽 31间断地形成在用于成形门胆的竖向侧面的阳 模 30的侧面 301上。 由此, 可以在门胆上形成与凹槽 31对应的多个彼此间隔设置的凹筋
11。
根据本发明的一些实施例, 凹槽 31构造成适于阳模 30的上表面的形状。 由此, 可以 使生产出的门胆的门胆本体 10的竖向 (参见 3、 图 4 )侧面 101具有与地面 102的外轮廓 相同的凹筋 11。 .
根据本发明的一个实施例, 阳模 30的表面上形成有吸附口(未示出), 吸附孔用于在吸 塑的过程中吸附板材 100与阳模 30相对的表面。
在本说明书的描述中, 参考术语 "一个实施例"、 "一些实施例"、 "示意性实施例"、 "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发明的至少一个实施例或示例中。 在本说明书中, 对上述术语 的示意性表述不一定指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。
尽管已经示出和描述了本发明的实施例,本领域的普通技术人员可以理解,在不脱离本 发明的原理和宗旨的情况下可以对这些实施例进行多种变化、 修改、 替换和变型, 本发明 的范围由权利要求及其等同物限定。
