具体实施方式
实施例一
如图1所示，本发明一种粉末投放装置，包括投放容器1，在投放容器1顶部进料口处设置有可开合的密封盖2封闭进料口，在投放容器1底部投放口5处设置有可开合的密封件6封闭投放口5，在投放容器1内设置有送料装置将投放容器1内的粉末定量从底部投放口5送出。
在投放容器1顶部进料口处设置有可开合的密封盖2通过旋转轴3与投放容器1可转动连接。
如图1、2所示，在投放容器1及密封盖2上还设置有相互配合进而使投放容器1及密封盖2锁合的卡扣7与凸起8。
卡扣7及凸起8设置在投放容器1及密封盖2上与旋转轴3相对的一端。
卡扣7为片状结构，上端与密封盖2固定连接，下端悬空，在卡扣7上设置有孔23；凸起8为板状，一端与投放容器1外壁固定连接，一端悬空，在密封盖2扣合在投放容器1进料口上时，凸起8的悬空端插入卡扣7的孔23内，将密封盖2与投放容器1锁合。
为了能在卡扣7与凸起8之间卡合时更容易，凸起8的悬空端的上端设有倒角9。
在密封盖2下方设置有凹槽13，凹槽内设置有密封条14，在密封盖2扣合在投放容器1上后，投放容器1的顶部边沿嵌入密封盖2的凹槽13内并挤压密封条14，使密封盖2与投放容器1密封更好。
如图1、4所示，在投放容器1外部的下部设置有支座4,用于将投放容器安装在洗衣机上。
在投放容器1底部投放口5处设置有可开合的密封件6为弹性件，包括相互连接的固定端21和密封端22，密封件6的密封端22面积大于投放口5并贴合在投放口5下方，在密封端22的外周的局部设置有一个上向延伸的固定端21。固定端22与投放口5外壁固定连接，密封端22封闭投放口5并能在投放口5处的粉末挤压下弹性变形从而打开投放口5，粉末从投放口5投出。粉末投放完成后，密封件6在自身弹性恢复力的作用下，再次密封投放口。
结合图4和图5，投放容器1内设有相互隔离的投放容腔15和防潮容腔10，防潮容腔10顶部开放、底部封闭，防潮容腔10内设置有吸潮剂11及加热模块12作为防潮模块，隔离形成防潮容腔10的部分壁的顶部低于投放容器1的壁的顶部，在密封盖2 扣合在投放容器1进料口上时，防潮容腔10顶部与投放容腔15顶部连通。通过放置在防潮容腔10内的吸潮剂11及加热模块12，通过防潮容腔10顶部与投放容腔15顶部的连通空间，对放置在投放容腔15的粉末进行吸潮，防止粉末吸潮结块。
在投放容器1的投放容腔15内固定设置有电机16，电机16的输出轴连接输送螺杆19的上端，输送螺杆19上部设置有刮片25和螺旋叶片18，用于将投放容腔15内的粉末向下输送从投放口5内投放。为了使投放容腔15内的粉末更好地聚集和压实，在投放容腔15底部设计为漏斗腔24。
投放粉末时，电机16动作驱动输送螺杆19转动，输送螺杆19上部设置的刮片25和螺旋叶片18将投放容腔15内的粉末刮落并逐渐压实、向投放口5方向输送，由于输送螺杆19的外径与投放口5的内径配合，故利用输送螺杆19的螺纹能定量输送粉末，实现投放，在输送螺杆19末端，由于输送螺杆19的不断转动，由输送螺杆19输送的粉末挤压密封件6的密封端22使其弹性变形从而打开投放口5实现粉末投放。粉末投放完成后，电机16停止动作，从而使输送螺杆19不再转动，密封件6在自身弹性恢复力的作用下，再次密封投放口。
本发明一种粉末投放装置，包括投放容器，在投放容器顶部进料口处设置有可开合的密封盖封闭进料口，在投放容器底部投放口处设置有可开合的密封件封闭投放口，在投放容器内设置有送料装置将投放容器内的粉末定量从底部投放口送出。由于设置了密封盖封闭进料口、密封件封闭投放口，使得投放容器内的粉末不容易吸潮结块或失效，并且防止了误投放，提高了投放精度。
实施例二
本实施例一种洗衣机，安装实施例一所述的粉末投放装置。
本发明一种洗衣机，洗衣机上安装有粉末投放装置，包括投放容器，在投放容器顶部进料口处设置有可开合的密封盖封闭进料口，在投放容器底部投放口处设置有可开合的密封件封闭投放口，在投放容器内设置有送料装置将投放容器内的粉末定量从底部投放口送出。由于设置了密封盖封闭进料口、密封件封闭投放口，使得投放容器内的粉末不容易吸潮结块或失效，并且防止了误投放，提高了投放精度。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
