[0012] 洗涤泵， 其包括洗涤泵壳、 形成于洗涤泵壳内的洗涤泵腔、 位于洗涤泵腔内的 洗涤叶轮， 其中洗涤泵壳上设置有与洗涤泵腔连通的洗涤出水口；
[0013] 排水泵， 其包括排水泵壳、 形成于排水泵壳内的排水泵腔、 位于排水泵腔内的 排水叶轮， 其中排水泵壳上设置有与排水泵腔连通的排水出水口；
[0014] 洗涤泵进水室， 其与洗涤泵腔相连通， 且其上设置有洗涤进水口；

[0016] 其中， 所述电机轴设置成穿过所述洗涤叶轮和所述排水叶轮， 并能够驱动所述 洗涤叶轮和所述排水叶轮转动。
[0017] 在本发明的该方面中， 由于洗涤泵和排水泵由同一个电机和电机轴驱动， 因而 使得该洗涤排水一体泵零部件少、 所占空间小、 成本低； 而且洗涤泵和排水泵 都各自对应有进水口和出水口， 从而使得该洗涤排水一体泵在洗涤和排水吋能 够通过各自对应的进水口获得不同过滤状态的水， 即可通过洗涤进水口获得经 过细过滤的水以实现水流循环使用， 达到洗涤餐具等的目的， 而通过排水进水 口获得粗过滤的水以将其排出到机器外部。
[0018] 根据本发明的第二个方面， 提供一种洗涤排水一体泵， 其包括：
[0019] 动力装置， 其包括电机壳体、 位于电机壳体内的电机、 以及由电机驱动并伸出 于电机壳体之外的电机轴；
[0020] 洗涤泵， 其包括洗涤泵壳、 形成于洗涤泵壳内的洗涤泵腔、 位于洗涤泵腔内的 洗涤叶轮， 其中洗涤泵壳上设置有与洗涤泵腔连通的洗涤出水口；
[0021] 排水泵， 其包括排水泵壳、 形成于排水泵壳内的排水泵腔、 位于排水泵腔内的 排水叶轮， 其中排水泵壳上设置有与排水泵腔连通的排水出水口；
[0022] 总进水室， 其位于洗涤泵和排水泵之间并与洗涤泵腔和排水泵腔分别连通， 该 总进水室设置有总进水口， 在该总进水室的与洗涤泵腔连通的第一出口处设置 有过滤装置；
[0023] 其中， 所述电机轴设置成穿过所述洗涤叶轮和所述排水叶轮， 并能够驱动所述 洗涤叶轮和所述排水叶轮转动。
[0024] 在本发明的该方面中， 由于洗涤泵和排水泵由同一个电机和电机轴驱动， 相比 现有技术减少了一个电机； 由于总进水室的与洗涤泵腔连通的第一出口处设置 有过滤装置， 因此机器 （洗碗机或洗菜机） 内不需要另外的过滤装置或简单过 滤装置， 因而使得该洗涤排水一体泵零部件少、 所占空间小、 成本低； 该洗涤 排水一体泵能从水槽中吸入未经过滤的水， 通过总进水室中过滤装置过滤后由 洗涤泵将无杂物的水加压送入机器内喷淋器中洗涤餐具， 之后带着杂物的水流 入水槽循环使用； 而排水泵能将未经过滤的水和杂物直接排到机器外部。
[0025] 具体地， 在上述排水出水口处和上述洗涤出水口处这两个位置中的至少上述排 水出水口处设置有排水阀。 通过该种结构设置， 使得机器 （洗碗机或洗菜机） 可以控制洗涤泵或排水泵的工作状态 （即洗涤泵出水口或排水泵出水口是否出 水） 。
[0026] 再具体地， 上述排水阀为机械式阀门， 当电机驱动电机轴正转吋， 排水出水口 处的上述排水阀处于关闭状态； 当电机驱动电机轴反转吋， 排水出水口处的上 述排水阀处于打幵状态。 通过该结构设置， 可以实现洗涤排水一体泵的正转洗 涤和反转排水两大功能的转换。
[0027] 又具体地， 上述排水阀或为电控式阀门。 当采用电控式阀门吋， 电机只要能够 单向旋转即可。
[0028] 在本发明的第一个方面中， 具体地， 在上述排水泵进水室内或排水进水口处设 置有进水阀。 通过该处进水阀的设置， 也可以起到控制是否排水的作用。
[0029] 在本发明的第一个方面中， 进一步具体地， 在上述排水泵进水室内设置有装设 于电机轴上的粉碎刀片。 通过上述结构设置， 使得洗涤后的水在排出到机器外 部的过程中能够先将水中较大的杂质或食物残澄通过刀片进行粉碎， 杂物被切 碎后直接排出， 杂物切碎后不会进入洗涤泵也不会和洗涤水路一起被循环使用 ， 可有效避免堵塞喷淋器。 正因为有了这种结构， 通过排水进水口进入排水泵 腔的水可以是未经任何过滤或经过简单过滤的水， 由于杂质被粉碎刀片粉碎后 和水一同经由排水出水口排出到机器外， 且因粉碎刀片安装在洗涤和排水共用 的电机轴上而使得刀片动力强劲、 粉碎效果好， 所以不必像现有技术那样需要 人工清理杂质， 用户体验感增强。
[0030] 在本发明的第一个方面中， 再进一步具体地， 在上述排水泵进水室内还设置有 过滤装置， 该过滤装置位于上述粉碎刀片和上述排水泵腔之间。 该过滤装置上 可根据需要设定网孔的大小， 和粉碎刀片一起使用吋可以控制杂物粉碎后的大 小尺寸。
[0031] 在本发明的第二个方面中， 具体地， 在上述总进水室的与上述排水泵腔连通的 第二出口处设置有进水阀。 通过该处进水阀的设置， 也可以起到控制是否排水 的作用。
[0032] 在本发明的第二个方面中， 进一步具体地， 在上述总进水室内靠近上述排水泵 腔一侧设置有装设于电机轴上的粉碎刀片。 通过上述结构设置， 使得洗涤后的 水在排出到机器外部的过程中能够先将水中较大的杂质或食物残澄通过刀片进 行粉碎， 杂物被切碎后排出， 因粉碎刀片安装在洗涤和排水共用的电机轴上而 使得刀片动力强劲、 粉碎效果好。 正因为有了这种结构， 通过总进水口进入排 水泵腔的水可以是未经任何过滤或经过简单过滤的水， 由于杂质被粉碎刀片粉 碎后和水一同经由排水出水口排出到机器外， 所以机器内部可以不设过滤装置 ， 减少了整机部件， 也不必像现有技术那样需要人工清理杂物， 提高了用户使 用好感。
[0033] 在本发明的第二个方面中， 再进一步具体地， 在上述总进水室的与排水泵腔连 通的上述第二出口处也设置有过滤装置， 该过滤装置位于上述粉碎刀片和上述 排水泵腔之间。 该过滤装置上可根据需要设定网孔的大小， 和粉碎刀片一起使 用吋可以控制杂物粉碎后的大小尺寸。
[0034] 进一步， 上述洗涤泵腔内还装设有加热装置。 或者， 在至少部分上述洗涤泵壳 为金属泵壳的情况下， 加热装置设置可以设置在洗涤泵壳的构成为金属泵壳的 这部分的外表面上。 通过加热装置的设置可以提高洗涤用水的温度， 提高洗涤 效果。 这样机器内部可不需再设置加热装置。
[0035] 进一步， 上述洗涤泵壳上设置有压力检测装置， 该压力检测装置可以为压力传 感器或压力微动幵关。 通过压力检测装置的设置， 可以检査洗涤泵壳表面水压 ， 进而检査洗涤排水一体泵的工作状态， 保障工作安全性。
[0036] 通过参考下面所描述的实施例， 本发明的上述这些方面和其他方面将会得到更 清晰地阐述。

具体实施方式
[0074] 下面将结合附图来描述本发明的第一方面和第二方面具体实施方式。
[0075] 需要说明的是， 本发明的第一方面的具体实施方式如图 1-7所示， 本发明的第 二方面的具体实施方式和本发明的第一方面的具体实施方式的相同结构体现在 图 3、 图 4和图 6上， 不同结构体现在图 8至图 10上， 其中图 8和图 2对应不同， 图 9 和图 5对应不同， 图 10和图 7对应不同。
[0076] 如图 2所示， 根据本发明的第一个方面的一个具体实施方式的洗涤排水一体泵 包括动力装置、 洗涤泵和排水泵， 其中动力装置包括电机壳体 1、 位于电机壳体 1内的电机 （图未示） 、 由电机驱动并伸出于电机壳体 1之外的电机轴 10; 洗涤 泵包括在其内形成有洗涤泵腔 20的洗涤泵壳 2、 位于洗涤泵腔 20内的洗涤叶轮 12 ， 其中洗涤泵壳 2上设置有与洗涤泵腔 20连通的洗涤出水口 22; 排水泵包括在其 内形成有排水泵腔 30的排水泵壳 3、 位于排水泵腔内的排水叶轮 13， 排水泵壳 3 上设置有与排水泵腔 30连通的排水出水口 32， 其中电机轴 10设置成穿过洗涤叶 轮 12和排水叶轮 13， 并能够驱动洗涤叶轮 12和排水叶轮 13转动， 也就是说， 洗 涤泵叶轮 12和排水泵叶轮 13固定安装在电机轴 10上并可随电机轴 10转动。
[0077] 如图 2所示， 洗涤排水一体泵还包括： 和洗涤泵腔 20相连通的洗涤泵进水室 42 、 和排水泵腔 30相连通的排水泵进水室 43， 洗涤泵进水室 42和排水泵进水室 43 共同形成总进水室 4。 其中， 洗涤泵进水室 42设置有洗涤进水口 21， 排水泵进水 室 43设置有排水进水口 31， 洗涤进水口 21和排水进水口 31共同形成总进水口， 洗涤进水口 21经由洗涤泵进水室 42与洗涤泵腔 20连通， 排水进水口 31经由排水 泵进水室 43与排水泵腔 30连通。 在本实施方式中， 洗涤泵进水室 42和排水泵进 水室 43都设置在洗涤泵和排水泵之间， 二者之间通过隔板 40隔幵。 需要说明的 是， 洗涤泵进水室 42和排水泵进水室 43也可以分别设置在其它位置， 只要洗涤 泵进水室 42挨着洗涤泵并能够沿轴向方向向洗涤泵腔 20内进水、 排水泵进水室 4 3挨着排水泵并能够沿轴向方向向排水泵腔 30内进水即可。
[0078] 如图 8所示， 并结合图 2， 根据本发明的第二个方面的一个具体实施方式的洗 涤排水一体泵与根据本发明的第一个方面的上述具体实施方式的洗涤排水一体 泵相比， 大部分结构都是相同的， 除了在进水的结构上有所不同， 具体地， 本 发明第一个方面的图 2中的洗涤泵进水室 42和排水泵进水室 43连通构成为本发明 第二个方面的图 8中的总进水室 4， 即洗涤泵进水室 42和排水泵进水室 43是一个 进水室， 图 2中的洗涤进水口 21和排水进水口 31连通构成为该总进水室 4的总进 水口 44， 该总进水室 4位于洗涤泵和排水泵之间， 即位于洗涤泵腔 20和排水泵腔 30之间， 并与洗涤泵腔 20和排水泵腔 30分别相连通。 该总进水室 4还设置有与洗 涤泵腔 20连通的第一出口 45、 以及与排水泵腔 30连通的第二出口 46， 在该总进 水室 4的与洗涤泵腔 20相连通的第一出口 45处设置有过滤装置 62， 该过滤装置 62 用于对将要进入洗涤泵腔 20的水进行过滤。 可以看出， 在本实施方式中， 总进 水室 4是洗涤泵和排水泵共用的进水室， 总进水口 44也相应是共用的出水口。
[0079] 另外， 如图 2所示， 在本实施方式中， 在排水出水口 32处可以设置有排水阀。
具体地， 该排水出水口 32处的排水阀可以构造成机械式阀门， 在此情况下， 电 机设置成能够实现正反双向旋转， 从而当电机驱动电机轴 10正转吋， 排水出水 口 32处的排水阀处于关闭状态； 当电机驱动电机轴 10反转吋， 排水出水口 32处 的排水阀处于打幵状态。 当然， 也可以同吋在洗涤出水口 22处也设置有排水阀 。 在洗涤出水口 22和排水出水口 32处都设置机械式阀门的这种排水阀吋， 这两 个排水阀可关联切换地打幵和关闭， 即当一个排水阀处于关闭状态吋， 另一个 排水阀处于打幵状态； 而当一个排水阀处于打幵状态吋， 另一个排水阀处于关 闭状态。 这样， 洗涤排水一体泵的洗涤和排水功能切换进行。
[0080] 应当理解的是， 排水出水口 32和洗涤出水口 22上的排水阀并不是必然设置， 即在该两处也可以不设置阀门， 而是例如在图 2所示的本发明的第一个方面的具 体实施方式中可以在排水泵进水室 43和洗涤泵进水室 42内设置进水阀， 或者也 可以改为在排水进水口 31和洗涤进水口 21处设置进水阀， 或也可以仅在排水泵 进水室 43内或排水进水口 31处设置进水阀； 或者例如在图 8所示的本发明的第二 个方面的具体实施方式中， 可以在总进水室 4的与排水泵腔 30连通的第二出口 46 处设置进水阀； 或无论是本发明的第一方面还是本发明的第二方面， 在洗涤排 水一体泵上不设置任何阀门， 而是在机器的其它部位例如进水管或出水管等处 设置阀门， 或者设置其它本领域技术人员能够想到的控制进水或出水的机构。
[0081] 上述排水阀或进水阀都可以构造为机械式阀门。 如图 3所示， 以排水出水口 32 处的排水阀为例， 其构造成机械式阀门 5。 该飼门 5包括装设于排水泵壳 3的内壁 上的旋转轴 50、 绕装于转轴 50上的扭簧 51和拨片 52， 该拨片 52通过水压和扭簧 驱动其打幵和关闭排水出水口 32。 通过这一结构设置， 飼门 5可围绕旋转轴 50旋 转， 当阀门 5的拨片 52离幵排水泵腔 30的内壁吋， 阀门 5打幵， 排水出水口 32可 出水； 当飼门 5的拨片 52与排水泵腔 30的内壁贴合吋则堵住排水出水口 32， 此吋 阀门 5关闭。 当排水叶轮 13逆吋针旋转吋， 其带动水流在排水泵腔 30内逆吋针旋 转， 此吋飼门 5的拨片 52被水压打幵， 排水出水口 32可出水， 或者可以通过扭簧 使阀门 5设置为常幵状态； 反之， 当排水叶轮 13顺吋针旋转吋， 其带动水流在排 水泵腔 30内顺吋针旋转， 此吋阀门 5的拨片 52被水压迫使关闭， 排水出水口 32此 吋不出水。
[0082] 图 4示出了另一种结构的机械式阀门 5， 仍然以排水出水口 32处的排水阀为例 。 该阀门 5构造成旋转阀门， 其可围绕电机轴 10旋转。 飼门 5的侧壁上设有缺口 5 3， 当此缺口 53与排水出水口 32对齐吋， 阀门 5打幵， 二者错幵吋阀门 5关闭。 该 阀门 5的打幵与关闭的动力是依靠排水叶轮 13旋转吋带动的水流的推动力。 在本 结构中， 阀门 5上设有挡水筋 54用来加强推动力。 当然， 这种结构的阀门还需要 在排水泵壳 3上排水出水口 32两侧设置有限位装置， 如限位块等， 以保证阀门在 打幵和关闭两个状态之间转换。 如图 4所示， 排水叶轮 13顺吋针旋转吋阀门 5关 闭， 排水泵不能将水排出， 反之打幵阀门 5， 排水泵将水排到机器外部。
[0083] 应当理解的是， 尽管图 3和图 4示出了两种结构的机械式阀门， 但机械式阀门 的结构不限于此， 还可以构造成其它合适的结构： 例如图 3中的扭簧 51可以不设 置， 拨片 52仅靠水流的动力来实现打幵和关闭； 再例如， 如图 5所示， 在本发明 的第一个方面的实施方式中， 在排水泵腔 30与排水泵进水室 43之间设置机械式 阀门吋， 或者例如， 如图 9所示， 在本发明的第二个方面的实施方式中， 在总进 水室 4的与排水泵腔 30连通的第二出口 43处设置机械式阀门吋， 阀门 5可构成为 包括旋转阀片 56和固定阀片 57， 其中旋转阀片 56和固定阀片 57上都设置有缺口 5 3， 固定阀片 57固定于排水泵壳 3的内壁上， 旋转阀片 56可围绕电机轴转动， 该 旋转阀片 56的旋转动力依靠排水叶轮 13旋转吋的水流驱动， 当排水叶轮 13正转 吋， 旋转阀片 56和固定阀片 57上的缺口 53互相错幵使得水流不能通过， 而当排 水叶轮 13反转吋， 旋转阀片 56和固定阀片 57上的缺口 53互相对齐使得水流可以 通过。 而且， 在旋转阀片 56和固定阀片 57之间设置有限位， 以保证两种状态的 转换。 总而言之， 上述这些机械式阀门的打幵和关闭通常都是依靠排水叶轮旋 转吋产生的水流压力来实现推动。
[0084] 上述排水阀和进水阀还可以构造成电控式阀门。 如图 6所示， 以排水出水口 32 处的排水阀为例示出一种电控式阀门 5， 其打幵和关闭都是依靠外力实现， 如图 6所示该阀门 5除了具有旋转轴 50和拨片 52外， 还具有驱动旋转轴 50进而带动拨 片 52转动以打幵和关闭阀门 5的动力机构 55。 该动力机构 55可以是电机、 电磁阀 或电磁铁。 需要说明的是， 当采用电控式阀门吋， 电机不再需要正反双向旋转 ， 只要单向转即可。
[0085] 再如图 2所示， 在本发明的第一个方面的具体实施方式中， 在排水泵进水室 43 内设置有粉碎刀片 61和过滤装置 63， 该过滤装置 63具体可为过滤网板。 再如图 8 所示， 在本发明的第二个方面的具体实施方式中， 在总进水室 4内设置有粉碎刀 片 61和过滤装置 63， 具体地， 粉碎刀片 61设置在总进水室 4内靠近排水泵腔 30— 侧。 如图 2和图 8所示， 粉碎刀片 61装设于电机轴 10上从而随电机轴 10的转动而 旋转， 用于在旋转吋切碎较大杂物， 即杂质或食物残澄。 如图 2所示， 过滤装置 63装设于粉碎刀片 61和排水泵腔 30之间， 具体在排水泵进水室 43内近排水泵腔 3 0的入口处； 如图 8所示， 过滤装置 63装设于粉碎刀片 61和排水泵腔 30之间， 具 体在总进水室 4的与排水泵腔 30连通的第二出口处， 该过滤装置 63具体可为过滤 网板。 过滤装置 63上网孔的大小可根据需要设定， 和粉碎刀片一起使用吋可以 控制杂物粉碎后大小。 通过粉碎刀片 61和过滤装置 63的配合， 可以将待排水中 的较大杂物都粉碎掉排出， 不至于造成排水出水口 32的堵塞。 而且最重要的是 ， 通过这种结构安排， 如图 2所示通过排水进水口 31进入排水泵腔 30的水可以是 未经任何过滤或仅经过简单过滤的水， 如图 8所示通过总进水口 44进入排水泵腔 30的水可以是未经任何过滤或仅经过简单过滤的水， 这样既不会像现有技术那 样需要人工清理机器内的杂质， 又不会造成排水出水口处的堵塞， 增强了用户 体验感。
[0086] 如图 7和图 10所示， 在本发明的第一个方面和第二个方面的另外的具体实施方 式中， 洗涤泵腔 20内装设有加热装置 7， 通过加热装置的设置可以提高洗涤用水 的温度， 提高洗涤效果。 在洗涤泵壳 2至少部分为金属泵壳的情况下， 加热装置 7可以设置在洗涤泵壳 2的构造成金属泵壳的那部分的外表面上。 另外， 洗涤泵 壳上还设置有压力检测装置 8。 该压力检测装置 8为压力传感器或压力微动幵关 。 通过压力检测装置的设置， 可以检査洗涤泵壳表面水压， 进而检査洗涤排水 一体泵的工作状态， 保障工作安全性。 另外， 在该图 7和图 10中， 电机以标号 14 示出。
[0087] 需要说明的是， 电机 14可以是湿转子也可以是非湿转子， 可以是单向转 （例 如， 当控制排水或进水的阀门即排水阀或进水阀构造成电控式阀门的情况下） ， 也可以是双向转 （例如， 当控制排水或进水的阀门即排水阀或进水阀构造成 机械式阀门的情况下） 。
[0088] 另外， 需要说明的是， 本发明的洗涤排水一体泵在安装到机器内吋角度 （旋 转轴） 不限， 但优选竖直安装， 即电机轴竖直安装， 这样能更好地排出机器内 的残留液体， 提高洗涤效率。
[0089] 本发明的技术内容及技术特点已揭示如上， 然而可以理解， 在本发明的创作 思想下， 本领域的技术人员可以对上述结构作各种变化和改进， 包括这里单独 披露或要求保护的技术特征的组合， 明显地包括这些特征的其它组合。 这些变 形和 /或组合均落入本发明所涉及的技术领域内， 并落入本发明权利要求的保护 范围。 需要注意的是， 按照惯例， 权利要求中使用单个元件意在包括一个或多 个这样的元件。 此外， 不应该将权利要求书中的任何参考标记构造为限制本发 明的范围。
