此外，还需要理解的是，在本实施例中，术语“下”、“上”、“前”、“后”、“左”、“右”、“内”、“外”、“顶”、“底”、“一侧”、“另一侧”、“一端”、“另一端”、等所指示的位置关系为基于附图所示的位置关系；“第一”、“第二”等术语，是为了区分不同的结构部件。这些术语仅为了便于描述本公开和简化描述，不能理解为对本公开的限制。
如图1所示，一方面，本公开涉及一种吸料组件100，包括：第一管道110，第一管 道的进口端1120用于与供粉装置500连接并连通；及第二管道120，第一管道的出口端1140设置于第二管道120内，第二管道120的外壁与第一管道110的内壁间隔设置形成抽气间隙102，抽气间隙的出口1020远离第一管道的出口端1140设置，抽气装置200通过抽气间隙102与第一管道的出口端1140连通，第二管道的出口端1220用于与洗碗机内胆600连接并连通。
上述吸料组件100在使用时，抽气装置200通过与抽气间隙102连通，抽气装置200在抽气过程中产生压力能够将洗涤粉末从供粉装置500传送到第一管道110内，并在重力作用落到洗碗机内胆600内，达到投放洗涤粉的目的；进一步，由于第一管道的出口端1140设置于第二管道120内，抽气间隙的出口1020远离第一管道的出口端1140设置，如此，第一管道110和第二管道120可以形成一个迂回的通道，进而确保洗涤粉不被吸入抽气装置200内，因此，该吸料组件100可以把控吸取洗涤粉的量，也就是可以控制洗涤粉进入洗碗机内胆600的量，进而提升洗涤粉的利用率。
如图1所示，在上述实施例的基础上，该吸料组件100还包括中间管道130，中间管道130包括贯穿中间管道130的侧壁的抽气通孔132，第一管道110和第二管道120设置于中间管道130，抽气间隙102设置于中间管道130内，抽气装置200通过抽气通孔132与抽气间隙102连通。由于抽气间隙102的间隙较小，将抽气间隙102设置于中间管道130内，通过抽气通孔132来连通抽气装置200及抽气间隙102，便于抽气装置200与抽气间隙102之间的安装及连通。
如图1所示，具体到本次实施例中，第一管道110及第二管道120均与中间管道130的内壁密封连接，抽气间隙102设置于中间管道130内，且中间管道130的内壁、第一管道110的外壁和第二管道120外壁之间设有抽气通道134，抽气通道134与抽气间隙102连通，抽气通孔132用于连通抽气通道134及抽气装置200，第二管道的出口端1220通过中间管道130的出口端与洗碗机内胆600连接并连通。如此，第一管道110和第二管道120均与中间管道130的内壁密封连接，抽气装置200在工作时，抽气通道134及第一管道110容易形成负压，进而洗涤粉能够从供粉装置500传输到第一管道110内，实现洗涤粉的自动投放。
如图1和图2所示，进一步，在本次实施例中，抽气通道134包括第一段抽气通道1342，第一管道110包括与中间管道130密封连接的第一密封段116及第一连接段114，第一密封段116的一端为第一管道的进口端1120，第一密封段116的另一端与第一连接段114连接，第一连接段114的另一端为第一管道的出口端1140，第一连接段114的外径小于第一密封段116的外径，第一连接段114设置于第二管道120内形成抽气间隙102，且第一密 封段116的端部与第二管道的进口端1240间隔设置形成第一段抽气通道1342，第一段抽气通道1342与抽气间隙102连通。如此，第一段抽气通道1342与抽气间隙102之间形成“曲折”通道，进而可以阻挡洗涤粉进入抽气装置200内。
如图1所示，进一步，在本次实施例中，第一管道110包括抵接凸起112，抵接凸起112设置于第一密封段116的外壁，抵接凸起112与第一密封段116的外壁配合形成抵接缺口，抵接缺口与中间管道的进口端抵接，如此，且通过抵接缺口与中间管道的进口端抵接，进一步提升密封效果。
如图1所示，在上述任一实施例的基础上，第一管道110的外壁与中间管道130的内壁螺纹连接。如此，通过螺纹连接的方式实现第一管道110的外壁与中间管道130的内壁密封连接；当然了，在别的实施例中，还可以通过在第一管道110的外壁及中间管道130的内壁之间设置密封圈的方式实现第一管道110的外壁与中间管道130的内壁之间密封连接。在本次实施例中，第一密封段116为螺杆，通过螺杆与中间管道130的内壁螺纹连接。
如图1和图2所示，进一步，具体到本次实施例中，抽气通道134包括第二段抽气通道1344，第二管道120包括与中间管道130的内壁密封连接的第二密封段122及第二连接段124，第二连接段124的一端为第二管道的进口端1240，另一端与第二密封段122连接，第二密封段122的另一端为第二管道的出口端1220，第二连接段124与中间管道130的内壁间隔设置形成第二段抽气通道1344，第二段抽气通道1344与抽气间隙102连通。如此，第二段抽气通道1344与抽气间隙102形成之间形成“曲折”通道，进而可以阻挡洗涤粉进入抽气装置200内。在本次实施例中，第二段抽气通道1344与第一段抽气通道1342就抽气间隙102连通，形成多段曲折的抽气通道，进而可以阻挡洗涤粉进入抽气装置200内。在本次实施例中，第二密封段122的高度低于抽气通孔132的高度，进而，第二密封段122与中间管道130的内壁形成一个容纳槽，可以收纳移动通道内的洗涤粉，避免洗涤粉进而抽气装置200。
如图1所示，在本次实施例中，中间管道130的内壁设有环形凸起136，第二密封段122的另一端与环形凸起136的承压面抵接，如此，通过将第二密封段122的另一端与环形凸起136的承压面抵接，进一步提升密封效果。
如图1所示，进一步，在上述任一实施例的基础上，第二管道120的外壁与中间管道130的内壁螺纹连接。如此，通过螺纹连接的方式实现第二管道120的外壁与中间管道130的内壁密封连接；当然了，在别的实施例中，还可以通过在第二管道120的外壁及中间管道130的内壁之间设置密封圈的方式实现第二管道120的外壁与中间管道130的内壁之间密封连接。在本次实施例中，第二密封段122为螺杆，通过螺杆与中间管道130的内壁螺 纹连接。
如图1所示，进一步，在上述任一实施例的基础上，第一管道的出口端1140的横截面的面积沿第一管道110的流通方向逐渐降低。如此，第一管道的出口端1140呈圆台状，可以起到导向作用，便于第一管道的出口端1140伸进中间管道130内。
如图1所示，进一步，具体到本次实施例中，第一管道110包括第一段通道1102和第二段通道1104，第一段通道1102的一端设有进气口，另一端与第二段通道1104的一端连接并连通，第二段通道1104的另一端设有出气口，第二段通道1104的内径沿进气口至出气口的方向逐渐降低。如此，第二段通道1104可以起到导向“收缩”作用，便于洗涤粉进入第二管道120内。
如图3所示，另一方面，本公开还涉及一种投料机构，一实施例中的投料机构包括上述任一实施例中的吸料组件100，还包括抽气装置200，抽气装置200的抽气端与抽气间隙102连通。
上述投料机构在使用时，抽气装置200通过与抽气间隙102连通，抽气装置200在抽气过程中产生压力能够将洗涤粉末从供粉装置500传送到第一管道110内，并在重力作用落到洗碗机内胆600内，达到投放洗涤粉的目的；进一步，由于第一管道的出口端1140设置于第二管道120内，抽气间隙的出口1020远离第一管道的出口端1140设置，如此，第一管道110和第二管道120可以形成一个迂回的通道，进而确保洗涤粉不被吸入抽气装置200内，因此，该吸料组件100可以把控吸取洗涤粉的量，也就是可以控制洗涤粉进入洗碗机内胆600的量，进而提升洗涤粉的利用率。
如图3所示，在上述实施例的基础上，该投料机构还包括控制阀300，控制阀300的进口与第二管道的出口端1220连通，控制阀300的出口与洗碗机内胆600连接并连通。如此，一方面，当控制阀300关闭时，可以起到对洗碗机内胆600进行密封的作用，避免洗碗机内胆600的洗涤水进入第二管道120内，造成污染或腐蚀。具体地，控制阀300可以是电磁阀等。
如图3所示，具体地，在本次实施例中，该投料机构还包括控制器400，控制器400与抽气装置200及控制阀300通信连接。如此，洗碗机工作时，控制器400控制控制阀300和抽气装置200打开，在抽气装置200的作用下，使得第一管道110及抽气通道134内部形成负压，如此，洗涤粉即可从供粉装置500沿吸到第一管道110内，由于重力作用洗涤粉落到洗碗机内胆600内，达到投放洗涤粉的目的，当不需要洗涤粉的时候，控制器400控制控制阀300和抽气装置200关闭，进而控制阀300可以密封洗碗机内胆600，防止洗涤水进入第二管道120内部，造成污染或者腐蚀。具体地，控制器400可以是微控制单元 或者是单片机等装置，在本次实施例中，控制器400与控制阀300和抽气装置200电性连接。
如图3所示，另一方面，本公开还涉及一种洗碗机，一实施例中的洗碗机包括上述任一实施例中的投料机构，还包括洗碗机内胆600，洗碗机内胆600与第二管道的出口端1220连通。
上述洗碗机在使用时，抽气装置200通过与抽气间隙102连通，抽气装置200在抽气过程中产生压力能够将洗涤粉末从供粉装置500传送到第一管道110内，并在重力作用落到洗碗机内胆600内，达到投放洗涤粉的目的；进一步，由于第一管道的出口端1140设置于第二管道120内，抽气间隙的出口1020远离第一管道的出口端1140设置，如此，第一管道110和第二管道120可以形成一个迂回的通道，进而确保洗涤粉不被吸入抽气装置200内，因此，该吸料组件100可以把控吸取洗涤粉的量，也就是可以控制洗涤粉进入洗碗机内胆600的量，进而提升洗涤粉的利用率。
如图3所示，在上述实施例的基础上，该洗碗机还包括供粉装置500，供粉装置500与第一管道的进口端1120连接并连通。具体地，可以通过送料管700连通供粉装置500及第一管道110，实现供粉装置500将洗涤粉传输至第一管道110内。供粉装置500可以是供粉盒或者是供粉袋或者是供粉瓶等。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本公开的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干变形和改进，这些都属于本公开的保护范围。因此，本公开专利的保护范围应以所附权利要求为准。
