滚筒洗衣机及其门体和喷淋系统 技术领域
[0001] 本发明属于家用电器领域，具体提供一种滚筒洗衣机及其门 体和喷淋系统。 背景枝术
[0002] 现有滚筒洗衣机发源于欧洲， 其由外至内主要包括箱体、外 筒和内筒。 滚筒洗衣机的工作方式与棒锤击打衣物原理类似。 工作时， 内筒在驱动电机的带动下转动。 随着内筒的转动， 衣物在滚筒中不断地 被提升摔下， 再提升再摔下， 做重复运动。 在洗衣粉和水的共同作用下， 衣物被洗涤干净。
[0003] 为了提高水流冲洗和漂洗衣物的效果，有的滚筒洗衣机还设 置有循环喷淋装置。 如公开号为 CN201037211的专利文献中公开的滚筒 式洗衣机， 其观察窗玻璃 （门体） 的内侧安装喷淋装置。 该喷淋装置包 括多个等间距、 圆周布置的喷嘴或喷射孔， 每一个喷嘴或喷射孔都指向 滚筒 （外筒） 口， 将洗涤水喷向滚筒内， 对衣物进行循环冲洗。
[0004] 虽然公开号为 CN20103721 1的专利文献中公开的滚筒式洗 衣机对衣物的清洁能力较强， 但是喷淋装置需要借助安装结构才能安装 到门体上， 其安装结构复杂， 并且门体开启时喷淋装置会裸露在用户的 视野中， 不够美观， 用户使用体验较差。
[0005] 相应地， 本领域需要一种新的滚筒洗衣机来解决上述问题。 发明内容
[0006] 为了解决现有技术中的上述问题，即为了解决现有具有循环 喷淋功能的滚筒洗衣机的喷淋装置安装结构复杂、 不美观的问题， 本发 明提供了一种用于滚筒洗衣机的门体， 所述门体设置有空腔、 与所述空 腔连通的进水孔和与所述空腔连通的多个喷射孔； 其中， 所述多个喷射 孔设置在所述门体的内侧。
[0007] 在上述喷淋系统的优选技术方案中，每一个所述喷射孔都设 置成扁平结构。 [0008] 在上述喷淋系统的优选技术方案中，所述扁平结构包括喇叭 状扁平结构或八字形扁平结构。
[0009] 在上述喷淋系统的优选技术方案中，所述多个喷射孔绕所述 门体的周向等间距设置。
[0010] 在上述喷淋系统的优选技术方案中，所述空腔是形成在所述 门体内的环形空腔、 圆形空腔或弧形空腔。
[0011] 在上述喷淋系统的优选技术方案中，所述门体包括固定连接 的本体和玻璃观察窗， 所述多个喷射孔设置在所述玻璃观察窗上。
[0012] 在上述喷淋系统的优选技术方案中，所述玻璃观察窗具有凹 槽结构， 所述门体还包括密封盖板， 所述密封盖板与所述凹槽结构的侧 壁密封连接并因此形成所述空腔。
[0013] 在上述喷淋系统的优选技术方案中，所述进水孔通过出水管 连接到设置在所述箱体或所述外筒上的循环泵的出水口， 所述循环泵的 进水口通向所述外筒内。
[0014] 此外， 本发明还提供了一种用于滚筒洗衣机的喷淋系统， 所 述喷淋系统包括循环泵、 出水管和上述喷淋系统的优选技术方案中任一 项所述的门体； 所述循环泵设置在所述箱体或所述外筒上， 所述循环泵 的进水口通向所述外筒内， 所述循环泵的出水口通过所述出水管与所述 门体的进水孔连通； 工作时， 所述循环泵将所述外筒中的洗涤水泵送给 所述空腔， 所述多个喷射孔将洗涤水喷射到所述内筒中。
[0015] 进一步， 本发明还提供了一种滚筒洗衣机， 所述滚筒洗衣机 包括上述的喷淋系统。
[0016] 本领域技术人员能够理解的是， 在本发明的优选技术方案 中， 通过在门体上设置空腔、 与所述空腔连通的进水孔和与所述空腔连 通的多个喷射孔， 使得循环泵能够将外筒中的洗涤水泵送给空腔， 继而 由多个喷射孔将洗涤水喷射到内筒中。 因此， 本发明的滚筒洗衣机依托 于门体自身就能够实现喷淋洗涤水的功能，与公开号为 CN201037211的专 利文献中公开的滚筒式洗衣机相比， 省去了喷淋装置的设置， 并并需要 在门体的内侧设置安装结构， 优选了门体的外观。 附图说明

[0025] 本领域技术人员应当理解的是，本节实施方式仅仅用于解释 本发明的技术原理， 并非用于限制本发明的保护范围。 例如， 虽然本发 明是以具有扁平结构的喷射孔来进行说明的， 但是本发明的喷射孔还可 以是其他任意结构形式的喷射孔。 本领域技术人员可以根据需要对其作 出调整， 以便适应具体的应用场合， 调整后的技术方案仍将落入本发明 的保护范围。
[0026] 还需要说明的是， 在本发明的描述中， 除非另有明确的规定 和限定， 术语 “安装” 、 “相连” 、 “连接” 应做广义理解， 例如， 可 以是固定连接， 也可以是可拆卸连接， 或一体地连接； 可以是机械连接， 也可以是电连接； 可以是直接相连， 也可以通过中间媒介间接相连， 可 以是两个元件内部的连通。 对于本领域技术人员而言， 可根据具体情况 理解上述术语在本发明中的具体含义。
[0027] 如图 1所示， 本发明的滚筒洗衣机主要包括箱体 1、外筒 2、 内筒 3、 门体 4、 密封窗垫 5、 排水泵 6和排水管 7。 其中， 外筒 2固定 地设置在箱体 1 内， 内筒 3可转动地设置在外筒 2中， 密封窗垫 5设置 在箱体 1和外筒 2之间。 排水泵 6和排水管 7都设置在箱体 1内， 并且 排水泵 6的进水口通向外筒 2的内底部， 排水泵 6的出水口与排水管 7 的一端连接， 排水管 7的另一端通向外界。 排水泵 6能够将外筒 2内的 洗涤水通过排水管 7排出。 [0028] 此外， 本领域技术人员能够理解的是， 在排水管 7的每个部 位都低于外筒 2的内底端时， 本领域技术人员还可以根据需要， 省去排 水泵 6 , 将排水泵 6替换成截止阀。 当滚筒洗衣机需要排水时， 打开该截 止阀， 使外筒 2中的洗涤水在自身重力的作用下从排水管 7自动排出。
[0029] 继续参阅图 1， 箱体 1的前端 （图 1中箱体 1的左侧） 设置 有箱体口 （图中未标示） ， 外筒 2的前端 （图 1中外筒 2的左侧） 设置 有外筒口 （图中未标示） ， 内筒 3的前端 （图 1中内筒 3的左侧） 设置 有内筒口 （图中未标示） 。 密封窗垫 5的一端与外筒口的边缘密封连接， 密封窗垫 5的另一端与内筒口的边缘密封连接。 门体 4枢转地设置在箱 体 1上， 并且门体 4关闭时能够封闭所述箱体口， 防止外筒 2中的洗涤 水从箱体口溢出。
[0030] 如图 1至图 4所示， 本发明的门体 4主要包括本体 41、 玻 璃观察窗 42和密封盖板 43。 其中， 本体 41和玻璃观察窗 42固定连接或 一体制成。玻璃观察窗 42向门体 4的内侧（图 2中门体 4的下侧）凸起， 并且玻璃观察窗 42形成有凹槽结构 （图中未标示） 。 密封盖板 43设置 在该凹槽结构内， 并且与凹槽结构的侧壁密封连接， 并因此形成空腔 44。 其中， 对于空腔 44 , 本领域技术人员可根据需要， 将其设置成任意形式 的空腔， 例如环形空腔、 圆形空腔、 弧形空腔等。
[0031] 如图 1和图 4所示，密封盖板 43上设置有与空腔 44连通的 进水孔 45, 或者本领技术人员还可以根据需要， 将进水孔 45设置在玻璃 观察窗 42的侧壁上。 进一步， 为了方便进水孔 45与外界连通， 门体 4 内还设置有连接软管 47, 该连接软管 47的一端与进水孔 45密封连接， 该连接软管 47的另一端通向外界。 在本发明优选的实施方案中， 连接软 管 47的另一端从门体 4与箱体 1的枢转连接处通向外界。 此外， 本领域 技术人员还可以根据需要， 省去连接软管 47, 并将进水孔 45设置在玻璃 观察窗 42的侧壁上。
[0032] 继续参阅图 1和图 4， 门体 4的内侧设置有多个喷射孔 46。 在门体 4被关闭时， 每一个喷射孔 46都指向内筒口。 在本发明优选的实 施方案中， 多个喷射孔 46绕玻璃观察窗 42的周向等间距地设置在玻璃 观察窗 42上。 或者， 本领技术人员也可以根据需要， 将多个喷射孔 46 非等间距地设置在玻璃观察窗 42上。 [0033] 如图 2和图 3所示， 每一个喷射孔 46都设置成扁平结构， 该扁平结构优选地为喇叭状扁平结构或八字形扁平结构。 换句话说， 喷 射孔 46都设置成其横截面沿洗涤水流动的方向逐渐变长， 同时本领域技 术人员可根据需要， 选择性地使该横截面的宽度逐渐变小。 喷射孔 46借 助该扁平结构能够将洗涤水呈瀑布状或扇形的喷向内筒 3中。
[0034] 此外， 在保证内筒 3内的衣物能够被喷淋的前提下， 本领域 技术人员还可以根据需要， 将喷射孔 46设置成其他任意可行的形状， 例 如， 蜂窝状、 圆孔状、 三角形状。
[0035] 本领域技术人员能够理解的是， 在门体 4具有空腔 44、 进 水孔 45和出水孔 46的前提下， 门体 4还可以被设置成其他任意可行的 形式， 例如， 省去玻璃观察窗 42 , 或者采用其他结构代替玻璃观察窗 42。
[0036] 继续参阅图 1， 本发明的滚筒洗衣机还包括喷淋系统， 该喷 淋系统主要包括循环泵 8、 出水管 9和门体 4。 其中， 循环泵 8优选地设 置在箱体 1 内且与箱体 1固定连接。 或者本领域技术人员也可以根据需 要， 使循环泵 8与外筒 1固定连接。 循环泵 8的进水口通向外筒 2的内 部， 优选地， 循环泵 8的进水口通过进水管与外筒 2的底端连接。 或者 本领域技术人员也可以根据需要， 在保证该进水管位于外筒 2内液面以 下的情况下， 可以将进水管连接到外筒 2的任意位置。 循环泵 8的出水 口通过出水管 9和连接软管 47连通。
[0037] 如图 1和图 5所示， 本发明的喷淋系统工作时， 循环泵 8通 过出水管 9和连接软管 47将外筒 2中的洗涤水泵送给空腔 44 ,多个喷射 孔 46将洗涤水喷射到内筒 3中冲洗衣物。 当内筒 3高速运转时， 从喷射 孔 46喷出的水流能够快速穿过衣物， 并在离心力和重力的作用下进入外 筒 2中。
[0038] 需要说明的是， 本发明的排水泵 6和 /或循环泵 8可以是任 意可行的泵， 例如、 齿轮泵、 叶片泵、 蠕动泵、 离心泵等。
[0039] 本领域技术人员能够理解的是，在本发明的另一个可行的实 施方案中， 排水泵 6和循环泵 8可以被一个泵替代。 作为示例一， 省去 排水泵 6， 使循环泵 8的出水口分别与出水管 9和排水管 7连通， 并且为 出水管 9配置用于选择性地开启或关闭其的第一截止阀， 为排水管 7配 置用于选择性地开启或关闭其的第二截止阀。 当滚筒洗衣机执行喷淋作 业时， 第一截止阀开启， 第二截止阀关闭； 当滚筒洗衣机执行排水作业 时， 第一截止阀关闭， 第二截止阀开启。 作为示例二， 省去排水泵 6 , 并 为循环泵 8的出水口配置一个三通阀， 以便循环泵 8的出水口能够借助 该三通阀选择性地与出水管 9或排水管 7连通。 此外， 本领域技术人员 也可以根据需要， 使三通阀能够同时阻隔循环泵 8与出水管 9的连通以 及循环泵 8与排水管 7的连通。
[0040] 综上所述，本发明的喷淋系统在保证内筒 3中的衣物得到有 效喷淋的情况下，把喷射孔 46设置在了门体 4上，不仅不需要安装结构， 而且还保持了门体 4原有的外形结构。 同时喷射孔不会勾住伤害衣物。
[0041] 至此，已经结合附图所示的优选实施方式描述了本发明的技 术方案， 但是， 本领域技术人员容易理解的是， 本发明的保护范围显然 不局限于这些具体实施方式。 在不偏离本发明的原理的前提下， 本领域 技术人员可以对相关技术特征作出等同的更改或替换， 这些更改或替换 之后的技术方案都将落入本发明的保护范围之内。
