实施该发明的最佳实施例
本发明的最佳实施方式
[0026] 为使本实用新型实施例的目的、 技术方案和优点更加清楚， 下面将结合本实用 新型实施例中的附图， 对本实用新型实施例中的技术方案进行清楚、 完整地描 述。
[0027] 在本实用新型的描述中， 需要说明的是， 首先定义术语： 以靠近外桶盖轴线的 方向为"内"、 以远离外桶盖轴线的方向为"外"； 以及术语"上"、 "下"、 等指示的 方位或位置关系是以洗衣机正常使用状态下， 相对于使用者的位置来定义的， 仅是为了便于描述本实用新型和简化描述， 而不是指示或暗示所指的装置或元 件必须具有特定的方位、 以特定的方位构造和操作， 因此不能理解为对本实用 新型的限制。 此外， 术语"第一"、 "第二 "仅用于描述目的， 而不能理解为指示或 暗示相对重要性。
[0028] 参阅图 1-图 7， 是本实用新型所提出的洗衣机外桶盖的一个实施例， 附图中洗 衣机只示出了外桶和内桶处的结构， 其他结构省略。 洗衣机包括外桶 10和套装 在外桶 10内的内桶 20， 外桶 10的顶部设置有外桶盖 30， 内桶 20上设有平衡环 40 。 洗衣机内设置有循环喷淋装置， 在外桶盖 30处设置有喷嘴 50。
[0029] 本实施例中， 洗衣机外桶盖 30包括外桶盖本体和设置在外桶盖本体上的喷嘴 50 ， 喷嘴 50具有喷嘴盖 1和一体成型于外桶盖本体上的喷嘴腔 2， 外桶盖本体上设 有用于固定喷嘴盖 1的熔敷柱 3。 通过熔敷柱 3的受热熔敷， 使得喷嘴盖 1固定在 喷嘴腔 2上形成喷嘴 50; 采用熔敷的方式固定喷嘴盖 1， 避免了利用螺钉固定后 的高出， 这样设置喷嘴盖 1与平衡环 40之间的间距为安全距离就可保证安全性， 使得外桶盖 30安装后结构紧凑， 有利于洗衣机体积的减小， 有效容积比的增多
[0030] 本实施例中， 参见图 2和图 3所示， 在喷嘴盖 1上设有与熔敷柱 3相匹配的固定孔 11， 熔敷柱 3位于固定孔 11内。 通过设置与熔敷柱 3相匹配的固定孔 11， 使得喷 嘴盖 1安装到喷嘴腔 2上吋， 定位准确， 以及固定牢固。
[0031] 本实施例中， 将喷嘴盖 1安装到喷嘴腔 2上， 并使得熔敷柱 3位于固定孔 11内， 此吋利用热熔枪将熔敷柱 3伸出固定孔 11的部分熔敷， 设置固定孔 11具有锥形的 下端面， 也就是熔敷柱 3的下端部熔敷后的熔融液填充在固定孔 11的锥形的下端 面处， 这样避免熔融液凝固后高于此处的喷嘴盖下端面， 并且增加了熔融液与 固定孔 11的接触面积， 提高了喷嘴盖 1固定后的牢固性。
[0032] 本实施例中， 参见图 2所示， 喷嘴 50为内宽外窄的喇叭口型， 这样使得从喷嘴 5
0喷射到内桶 20的水流为瀑布形水流， 有利于增加水流喷射的宽度范围， 提高洗 衣机的洁净比。
[0033] 本实施例中， 参见图 6和图 7所示， 喷嘴盖 1具有水平的外端部 12和内端部 13， 设置内端部 13为水平方向， 有利于保证从喷嘴 50流出的水流的方向， 沿内端部 1 3向外延伸形成的弧面部 14， 弧面部 14与外端部 12连接。 弧面部 14为上凸的弧形 ， 使得喷嘴 50的内腔高度从外向内逐渐变小； 由于喷嘴 50在宽度方向上从外向 内逐渐变宽的喇叭形， 使得喷嘴 50在以外桶盖 30的轴线为中心的多个弧形截面 的面积相等， 也就是使得保证了在喷嘴 50内水流的压力不变， 保证瀑布水流的 喷洒范围。
[0034] 本实施例中， 参见图 6和图 7所示， 在喷嘴盖 1的内端部 13具有向上的凸起部 131 ， 在喷嘴 50的出水口处设置凸起部 131， 使得出水面积减小， 增加了出水水流的 压力， 同吋使得出水水流距离平衡环 40的距离增加， 有利于水流的喷射。
[0035] 本实施例中， 参见图 6所示， 外桶盖本体上还具有与喷嘴腔 2连通的向外伸出的 注水口 4， 注水口 4与外桶盖本体一体注塑成型， 注水口 4的轴线向下倾斜。 由于 循环管从外桶 10的下部将洗涤水输送到注水口 4， 注水口 4的轴线向下倾斜， 有 利于循环管内的洗涤水流入注水口 4， 较小水流在管路内的能量损失， 有利于水 流进入喷嘴 50。
[0036] 本实施例中， 参见图 2所示， 喷嘴腔 2具有左右两侧板 21和上板 22， 熔敷柱 3位 于侧板 21附近的外桶盖本体上， 每侧设置有三个熔敷柱 3。 为了进一步增加喷嘴 盖 1固定后的牢固性， 喷嘴 50还设置有螺钉固定， 在外桶盖本体上对应设置在螺 钉孔 5， 螺钉孔 5靠近喷嘴 50的入水口； 在喷嘴盖 1设置有与螺钉孔 5相匹配的螺 钉过孔 15， 有螺钉过孔 15位于弧面部 14、 靠近外端部 12处， 此处的下方没平衡 环 40， 对于高度没有特别严格的要求。
[0037] 本实施例中， 参见图 2和图 3所示， 在喷嘴腔 2内设置向下延伸的挡水板 23， 挡 水板 23设置在上板 22上、 向下延伸， 并与左右两侧板 21连接， 挡水板 23为弧形 板， 用于调整进入喷嘴 50的水流。 对于喷嘴盖 1与喷嘴腔 2的配合密封， 在喷嘴 盖 1的两侧设有凹槽 16， 喷嘴腔 2的左右两侧板 21的下端部位于凹槽 16内。 在喷 嘴盖 1的下表面设置有网状的加强筋 17， 有利于增加喷嘴盖 1的结构强度。
[0038] 以上所述， 仅是本实用新型的较佳实施例而已， 并非是对本实用新型作其它形 式的限制， 任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更 或改型为等同变化的等效实施例。 但是凡是未脱离本实用新型技术方案内容， 依据本实用新型的技术实质对以上实施例所作的任何简单修改、 等同变化与改 型， 仍属于本实用新型技术方案的保护范围。
