此外，为提高所述进排水通道8的密封性，所述中空丝杠43的外壁上设有所述密封槽431，所述密封槽431内设有密封件45，所述密封件45能将中空丝杠43与伸缩管41之间的间隙密封，从而避免水进入间隙内，造成排水组件的排水不畅以及因积水导致的不断沥水、长时间未排尽水而引发的细菌滋生等问题。
进一步地，通过控制组件6控制所述驱动组件3及进排水组件5的运行参数，可控制洗米开启时间、洗米速度、进排水的水量及进排水的次数，从而提高洗米效率及减少洗米对米粒的破坏，进而提升米饭的口感。
参见图2及图6，为驱动所述驱动套筒2运动，所述驱动套筒2的外壁设有齿轮环21，且所述齿轮环21与所述驱动套筒2一体成型或刚性连接。所述驱动组件3包括电机31及由所述电机31驱动的齿轮组件32；所述齿轮环21与所述齿轮组件32配合设置。其中，所述电机31设于所述驱动套筒2的外侧，所述电机31驱动带动所述齿轮组件32转动，从而驱动与齿轮组件32啮合的齿轮环21转动。所述齿轮组件32能增加所述驱动组件3的扭矩，在本实施例中，所述齿轮组件32包括与所述电机31连接的蜗杆321、与所述蜗杆321啮合的涡轮322、与所述涡轮322同轴设置的第一齿轮323及与所述第一齿轮323啮合的第二齿轮324；所述第二齿轮324与所述齿轮环21啮合，但不限于此。

参见图4至图6，所述导向滑动部44包括设于所述驱动套筒2内壁上的滑槽441及设于所述伸缩管41外壁上的滑块442；所述滑槽441与所述滑块442 配合设置。需要说明的是，在本实施例中，所述导向滑动部44不仅能在伸缩管41运动时提供导向，而且还能传递使驱动套筒2能带动伸缩管41同步转动的扭矩。为使伸缩管41向下运动时不会晃动，所述滑槽441沿所述伸缩管41的轴向设置，所述滑槽441至少设有两条，但不限与此。
参见图2，所述洗米搅拌组件7包括与所述伸缩管41的末端连接的搅拌座71及设于所述搅拌座71上的搅拌叶片72。所述搅拌座71与所述伸缩管41的末端连接，其连接方式包括但不限于螺纹连接，销钉连接等。所述搅拌叶片72与所述搅拌座71可拆洗连接，所述搅拌叶片72能带动米粒与水充分碰撞，从而快速清洗米粒。为防止搅拌叶片72与容器发生摩擦，破坏容器内的涂层，所述搅拌叶片72采用食品级塑料或橡胶材质制成，但不限于此。
进一步地，所述搅拌座71沿轴向设有贯通孔711，所述贯通孔711与所述进排水通道8连通，所述贯通孔711内设有滤网73，所述滤网73阻挡米粒被吸入贯通孔711内。
参见图2，所述进排水管52与外接管道连通，通过动力元件51向容器内加水或排水。为便于固定所述进排水管52，所述中空丝杠43的上端穿过所述固定管1，所述进排水管52套设在所述中空丝杠43内，且所述进排水管52上设有第二密封槽521，所述第二密封槽521内设有密封圈9，从而实现进排水管52与中空丝杠43的密封。所述中空丝杠43外还固定有锁紧螺母10，所述锁紧螺母10能提供一定的锁紧力，从而避免进排水管52与中空丝杠43松脱。
相应的，本发明还提供了一种采用所述复合洗米装置的洗米工艺，包括以下步骤：
S1、所述控制组件6控制所述驱动组件3启动，所述驱动套筒2同步转动，带动所述伸缩管41以第一速率V1转动；
其中，所述控制组件6通过控制所述电机31的转速来控制驱动套筒2的转速，进而控制所述伸缩管41与丝杠螺母42的转速，在中空丝杠43与丝杠螺母42参数确定的基础上，所述伸缩管41会以相应的速率上下运动。在未到达预定的加水位置时，所述伸缩管41及丝杠螺母42以第一速率V1转动，从而使伸缩管41快速下降至预定的加水工位，减少洗米工序的整体运行时间。
S2、所述丝杠螺母42沿所述中空丝杠43向下滑动，带动所述伸缩管41相对于所述驱动套筒2向下滑动，直至所述洗米搅拌组件7下降至预定高度；
需要说明的是，为防止加水时水溅射，根据煮饭的米量，所述控制组件6可控制所述伸缩管41下降至预定位置。
S3、所述控制组件6控制所述进排水组件5启动，向容器内加入预定的水量；
在伸缩管41下降至加水位置后，所述控制组件6控制所述动力元件51启动，向容器中加水，加水的水量根据水量可相应调整。当加入预定水量时，所述控制组件6会控制所述动力元件51停止运行。
S4、所述控制组件6控制所述驱动组件3使伸缩管41以第二速率V2转动，使所述洗米搅拌组件7同步旋转及升降以进行一次洗米；
在所述动力元件51向容器内加水的同时，所述控制组件6调控所述电机31的转速，使所述伸缩管41以第二速率V2转动，其中所述第二速率V2小于所述第一速率V1。优选的，V1＝120～360r/min，V2＝30～60r/min。以所述第二速率V2转动时，所述洗米搅拌组件7能满足充分搅拌米粒的同时避免因转速过快对米粒的破坏，提升米饭的口感。根据需要，所述控制组件6还可通过控制电机31的正转及反转，带动所述伸缩管41上下往复运动，从而多次洗米。需要说明的是，清洗完毕时，所述伸缩管41处于最低位置，以便能彻底排尽容器中的水。
S5、一次洗米完毕后，所述控制组件6控制所述进排水组件5启动，将容器内的水排出；
具体的，在一次洗米完成后，所述控制组件6控制所述动力元件51启动，将容器中的水快速排出，避免水长时间浸泡米粒，加速洗米效率。
S6、重复步骤S3至直至S5，直至洗米结束，所述控制组件6控制所述伸缩管41复位。
具体地，根据程序设定的洗米次数，所述控制组件6控制所述进排水组件5多次进排水，并通过所述驱动组件3控制伸缩管41进行多次往复升降及旋转运动，完成米粒的清洗。清洗完毕后，所述控制组件6通过电机31驱动所述驱动套筒2反向转动，使所述伸缩管41回缩至初始位置，完成洗米。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
