下面参考附图描述根据本申请实施例的投放装置100。
参照图1-图5、图8所示，根据本申请实施例的投放装置100可以包括：储液容器10、泵体20与驱动组件30。
具体而言，储液容器10用于储存洗涤液，泵体20安装于储液容器10，且泵体20具有泵头21，泵头21可以相对于储液容器10移动，以将储液容器10内的洗涤液泵出，以实现洗涤液投放，使洗涤液泵出方便、快捷，且使洗涤液每次泵出的液量可控。
此外，如图2-图4所示，驱动组件30用于驱动泵头21，以将储液容器10内的洗涤液泵入洗碗机的洗涤腔内，例如驱动组件30可以与泵头21相抵，并驱动泵头21向靠近储液容器10的方向移动，实现泵头21的按压，以将储液容器10内的洗涤液泵出，使洗涤液能够被泵入洗碗机的洗涤腔，换言之，泵头21向靠近储液容器10的方向移动时，可以将储液容器10内的洗涤液泵入洗碗机的洗涤腔，从而实现洗涤液的自动投放，且用户无需每次洗涤餐具前向洗涤腔手动投放洗涤液，避免了用户手工添加洗涤液与频繁投放洗涤液的痛点，使洗碗机的使用更方便，也避免出现用户忘记投放洗涤液而影响餐具洗涤效果的情况。
并且，驱动组件30驱动泵头21的过程中，洗涤液可以直接泵入洗碗腔内，而不通过其他管道连通，可以避免洗涤液残留，从而避免残留的洗涤液污染变质等问题，有利于提高洗碗机的卫生状态。
具体地，在一些实施例中，如图2-图5所示，驱动组件30可以包括驱动件31和传动件32，驱动件31与传动件32相连，并且驱动件31可以驱动传动件32移动，传动件32用于与泵头21配合，以在传动件32移动时可以驱动泵头21移动，例如与泵头21相抵并按压泵头21，实现洗涤液的泵出。
在一些具体实施例中，继续参照图2-图5所示，驱动件31可以驱动传动件32沿第一方向向靠近储液容器10的方向移动(例如沿图4中所示的上下方向向下移动)，以使传动件32与泵头21相抵，使传动件32能够驱动泵头21向靠近储液容器10的方向移动，由此实现洗涤液投放。
洗涤液投放过程中，储液容器10内的洗涤液直接通过泵头21泵入洗涤腔，而不会与驱动组件30接触，有效降低洗涤液泄漏的风险。且传动件32沿第一方向移动以驱动泵头21移动，传动阻力更小，避免出现传动件32或泵头21卡顿而影响洗涤液正常投放。此外，传动件32与泵头21相抵配合，在泵体20或驱动组件30发生损坏时，仅需更换损坏部件，有效降低了维修成本。在泵体20和储液容器10可拆卸的一些实施例中，还可以将传动件32与泵头21分离，拆装更容易。
需要说明的是，传动件32可以始终与泵头21相抵，也可以向靠近储液容器10的方向移动一定距离后再与泵头21相抵。例如，在一些实施例中，传动件32在初始位置时与泵头21分离，且传动件32可以在驱动件31的驱动下向下移动一定距离，使传动件32与泵头21相抵，传动件32继续向下移动，以驱动泵头21向下移动，从而将储液容器10内的洗涤液泵入洗涤腔，实现洗涤液的自动投放。
需要说明的是，为便于描述，本申请中“上下方向”和“左右方向”等方位是基于附图中所示方位关系，而并非对实际应用过程中方位的限定。
根据本申请实施例的投放装置100，通过驱动组件30驱动泵头21，例如通过驱动件31驱动传动件32沿第一方向向靠近储液容器10的方向移动，使传动件32驱动泵头21向靠近储液容器10的方向移动，以将储液容器10内的洗涤液泵入洗涤腔，实现洗涤液的自动投放，解决了用户手工添加洗涤液与频繁投放洗涤液的痛点，使洗碗机的使用更方便，且泵出的洗涤液完全进入洗涤腔内，可以避免洗涤液残留，使洗碗机更干净卫生。此外，传动件32和泵头21移动顺畅，不易卡顿或造成洗涤液泄漏，便于拆装且有利于降低维修成本。
根据本申请的一些实施例，如图4所示，驱动件31还可以驱动传动件32沿第一方向向远离储液容器10的方向移动，以使传动件32复位到初始位置，使驱动组件30复位，以便于再次投放洗涤液。
在本申请的一些实施例中，泵体20还包括复位件(例如复位弹簧)，在驱动组件30复位时，即驱动组件30处于按压泵头21的初始位置、对泵头21的按压程度最小时，例如在驱动组件30包括传动件32的实施例中、传动件32向远离储液容器10的方向移动以使驱动组件30复位时，复位件可以驱动泵头21向远离储液容器10的方向移动，以使泵头21复位到初始位置，便于驱动组件30再次按压泵头21，例如便于传动件32再次沿第一方向向靠近储液容器10的方向移动时，使泵头21可以再次向靠近储液容器10的方向移动。泵头21往复移动，实现洗涤液的多次投放，保证洗涤液的投放量，且投放简单、快捷。
例如，如图4所示，传动件32可以在驱动件31的驱动下向上移动，以取消对泵头21向下的驱动力，使复位件可以驱动泵头21向上移动，传动件32与泵头21复位。当传动件32再次向下移动时，传动件32驱动泵头21向下移动，将储液容器10内的洗涤液泵入洗涤腔，反复上述多次动作，以实现洗涤液的多次投放，保证洗涤液的投放量。
在相关技术中，洗碗机通过电机控制投放装置投放洗涤液，并通过控制电机工作预定时间控制洗涤液的投放量，由于电机转速不稳定，导致每次进行投放时，预定时间内的洗涤液投放量不固定。
例如，在一些具体实施例中，传动件32可以在第一预设位置和第二预设位置之间移动，例如在如图4所示的实例中，传动件32位于第一预设位置时的高度高于位于第二预设位置时的高度。传动件32由第一预设位置向第二预设位置移动时，驱动泵头21向靠近储液容器10的方向移动，以将储液容器10内的洗涤液泵入洗涤腔，传动件32由第二预设位置向第一预设位置移动时，泵头21可以向远离储液容器10的方向移动，以实现泵头21的复位，通过传动件32的上下移动，使洗涤液可以多次泵入洗碗腔，保证了洗涤液的投放量。并且传动件32和泵头21往复移动的行程一定，通过控制传动件32往复移动的次数即可控制洗涤液的投放量，投放量控制更容易。
根据本申请的一些实施例，储液容器10可更换，或者储液容器10内的洗涤液可添加，以保证投放装置100的长期使用。
例如，在一些实施例中，传动件32与泵头21可拆卸地配合，可靠性好，便于用户对泵体20与储液容器10的取放，方便更换新的泵体20与储液容器10，保证投放装置100内具有足够的洗涤液，能够 向洗涤腔内投放。例如，泵体20与储液容器10可以作为耗材整体进行更换，更换方便。
再例如，在一些实施例中，泵体20与储液容器10可拆卸地连接，在洗涤液液量不足时，用户可以拆卸泵体20与储液容器10，以向储液容器10内添加洗涤液，或者储液容器10可以作为耗材整体进行更换，确保储液容器10内具有充足的洗涤液，且操作方便，成本低。
或者，在一些实施例中，传动件32与泵头21可拆卸地配合，且泵体20与储液容器10可拆卸地连接，便于用户根据实际需要选择添加洗涤液的方式，以满足用户的不同的需求。
在本申请的实施例中，传动件32与泵头21可拆卸地配合的具体结构可以根据实际情况灵活设置。例如，传动件32与泵头21可以为卡接、紧固件连接等配合方式。
例如，在本申请的一些具体实施例中，如图3-图5所示，泵头21设有限位凹槽40，且传动件32的端部设有限位凸部41，限位凸部41插入限位凹槽40，限位凹槽40能够对限位凸部41起到限位作用，确保传动件32向下移动时对泵头21准确地施加作用力，不易偏移，使泵头21的受力可靠，且限位凸部41的下端与限位凹槽40的槽底面面接触，确保接触可靠，受力平稳，确保具有较好的投放量。
当然，限位凹槽40也可以设于传动件32，具体地，传动件32的端部设有限位凹槽40，且泵头21设有限位凸部41，限位凸部41插入限位凹槽40，这也在本申请的保护范围之内。
根据本申请的一些实施例，泵头21被构造成能够向洗涤腔内直接投放洗涤液，换言之，泵头21泵出的洗涤液不经过另外的管道即可进入洗涤腔内，从而避免管道过长导致洗涤液残留，有利于提高洗碗机的卫生状态。
在一些实施例中，泵头21上设有投放口，投放口被构造成直接连通洗涤腔，以使泵头21泵出的洗涤液由投放口泵出后，能够直接滴落至洗涤腔内，连通结构简单，且能够有效避免洗涤液残留。
根据本申请的一些实施例，图1-图5所示，投放装置100还包括座体50，泵体20可以固设于座体50，以使泵体20结构稳固，或者，泵体20可以可拆卸地设于座体50，以便于泵体20的维修和更换。
其中，泵体20和储液容器10可以设置成分体结构，也可以设置成一体结构，也就是说，可以将泵体20和储液容器10装配完成后装入到座体50上，也可以将泵体20和储液容器20分别安装到座体50上。
例如，将泵体20安装到座体50上，泵体20与座体50之间可以采用固定连接的方式，也可以采用可拆卸地连接的方式。储液容器10与泵体20设置成分体的结构，储液容器10可以设置成可拆卸地安装于座体50上，从而可以将储液容器10卸下以填充洗涤液，在储液容器10安装到座体50上之后，可以将储液容器10与泵体20相接，从而实现泵体20与储液容器10的连接，以便于泵送洗涤液。当然，在该实施方式中，也可以先将储液容器10安装到座体50上之后，再将泵体20安装到座体50上；还可以将储液容器10设置成不可拆卸地连接座体50的形式，并通过其他方式进行洗涤液的添加和更换。
另外，也可以将泵体20与储液容器10装配在一起后，然后将装配完成后的一体结构安装到座体50上，其中，泵体20与储液容器10可以为可拆卸地连接、也可以为不可拆卸地连接等。
在本申请的一些具体实施例中，泵体21与储液容器10可以集成为一体结构。需要说明的是，泵体21与储液容器10可以固定连接为一体，或者可以可拆卸地连接为一体，以使该一体结构可以一起移动，以便于操作，一体结构还可以减少机体上的安装结构，使装配简单，生产成本低。
具体地，该一体结构可以可拆卸地安装于机体上，例如安装于安装腔，以便于添加洗涤液，例如可以将一体结构拆下后再添加洗涤液，使操作方便。或者，该一体结构可以固设于机体上，如固设于安装腔，以使泵体21与储液容器10安装稳定，不易振动或损坏。
在一些实施例中，继续参照图1-图5所示，座体50具有沿第一方向延伸的导向通道51，传动件32至少一部分位于导向通道51内，以使传动件32能够在导向通道51的导向下移动，确保传动件32沿第一方向移动，从而确保传动件32移动过程中能够与泵头21准确配合。
在一些实施例中，座体50可以为洗碗机的门体或洗涤腔的腔壁，换言之，驱动组件30和储液容器10安装于洗碗机的门体或洗涤腔的腔壁，有利于减少零部件数量，减轻洗碗机的重量，实现洗碗机的轻量化。
在另一些实施例中，座体50可以安装于洗碗机的门体或洗涤腔的腔壁，便于投放装置100拆装以及洗涤液的添加。
在一些实施例中，如图4与图5所示，座体50还具有安装腔52与连通口53，储液容器10和泵体20安装于安装腔52，以使投放装置100外观整洁，也有利于防止投放装置100进水。连通口53连通导向通道51和安装腔52，传动件32穿设于连通口53，以使传动件32能够与泵头21相抵，便于传动件32驱动泵头21移动。
在包括座体50的一些实施例中，如图2所示，座体50具有安装腔52，安装腔52的腔壁设有过口522，泵头21可以穿过过口522并伸入洗涤腔内，以便于将储液容器10内的洗涤液输送至洗涤腔，实现洗涤液的添加，结构简单，有利于防止洗涤腔内的液体进入安装腔52而导致液体积存。
在本申请的一些实施例中，如图4与图5所示，投放装置100还包括密封件60，密封件60用于密封传动件32和连通口53的内周面之间的间隙，以避免灰尘、杂质、洗涤水等物质通过连通口53进入导向通道51内，防止驱动组件30进水损坏，保证驱动组件30正常工作。并且密封件60可以对传动件32的移动进行限位，确保传动件32沿第一方向移动。
在一些实施例中，如图1-图4所示，座体50包括座本体501和盖体502，座本体501具有安装腔52，安装腔52具有开口521，盖体502用于打开和关闭开口521，储液容器10安装于安装腔52内，以确保储液容器10稳固地位于安装腔52内，避免由于储液容器10的移动或掉出而影响洗碗机的正常使用，且便于添加洗涤液。
在泵体20与储液容器10可拆卸地连接的一些实施例中，通过盖体502打开开口521，便于对储液容器10进行取放拆装，以便于更换新储液容器10或向储液容器10内添加洗涤液。

例如，在一些实施例中，如图8所示，连接件312可以为偏心轮，偏心轮在驱动电机311的驱动下转动。偏心轮设有配合凸部313，传动件32设有配合凹槽321，配合凸部313可以沿配合凹槽321移动，以将偏心轮的转动转换为传动件32的移动，通过偏心轮做圆周运动或摆动可以带动传动件32往复运动，无需其他复位结构，结构简单，占用空间小，且生产成本低。
根据本申请的一些实施例，如图4与图8所示，配合凹槽321沿第二方向(例如图4中所示的左右方向)延伸，且偏心轮的转动轴线、第一方向和第二方向两两垂直，实现空间利用的最大化，降低占用空间，以减小投放装置100占用洗碗机的空间，提高了洗碗机的洗涤腔空间。
在本申请的一些实施例中，如图6-图8所示，投放装置100还包括投放量检测机构，投放量检测机构能够用于检测泵头21泵出的洗涤液的液量，从而实现洗涤液的投放量的检测，使洗涤液自动投放更准确，避免出现洗涤液不够而清洗不干净、或者洗涤液过多而漂洗不干净等问题。
在本申请的一些实施例中，泵头21被构造成能够在第一预设位置和第二预设位置之间往复运动，以投放洗涤液。投放量检测机构能够检测泵头21往复运动的次数，以获取泵出洗涤液的液量，使洗涤液投放量控制更准确。
根据泵头21往复运动的次数检测投放量，而非根据泵头21往复运动的工作时间控制洗涤液的投放量，从而不受泵头21往复运动的速度等因素的影响，能够在洗涤餐具时更准确控制洗涤液的投放量，且控制方便。
此外，通过投放量检测机构还可以检测泵头21是否复位等情况，避免泵头21发生卡死而影响洗涤液正常投放。
在一些实施例中，如图6-图8所示，投放量检测机构包括位置检测组件70，位置检测组件70用于检测泵头21的位置。
由此，可以根据位置检测组件70的检测结果判断泵头21往复运动的次数、位移等，进而判断洗涤液的投放量，使洗涤液投放量控制更准确。根据泵头21位置检测投放量，而非根据泵头21的工作时间控制洗涤液的投放量，从而不受泵头21往复运动的速度等因素的影响，能够在洗涤餐具时更准确控制洗涤液的投放量，且控制方便。
此外，通过位置检测组件70还可以检测驱动组件30驱动泵头21运动的驱动情况、是否复位等情况，避免驱动组件30或泵头21发生卡死而影响洗涤液正常投放。
在一些实施例中，投放量检测机构还包括控制组件，控制组件与位置检测组件70和驱动组件30相连，控制组件可以根据位置检测组件70的检测结果控制驱动组件30的工作状态。例如，可以在根据位 置检测判断洗涤液投放量达到所需液量时，可以控制驱动组件30停止工作；或者可以根据位置检测判断驱动组件30或泵头21卡死时，可以控制驱动组件30停止工作，还可以控制投放装置100发出故障提醒信息，以提醒用户进行维修。
在一些实施例中，在位置检测组件70检测到泵头21移动至第一预设位置时，控制组件计数，以确定投放量，保证泵头21单次往复运动的投放量固定、精准。
此外，并在计数值达到预设阈值时，控制组件可以控制驱动组件30停止工作。在泵头21每次移动至第一预设位置时表示完成了一次完整投放，且保证每次完整投放的投放量固定。通过对泵头21往复运动的次数进行控制，以对洗涤液进行定量投放的次数进行控制，从而对每次洗涤过程中洗涤液的投放量进行准确的控制，保证了洗涤液的投放精度，从而确保了洗碗机的洗净性能。
在驱动组件30包括驱动电机311的一些实施例中，在计数值达到预设阈值时，控制组件可以切断驱动电机311的电源，不仅停止投放洗涤液，而且可以降低能量损耗，节省电量，有利于实现洗碗机的低能耗。
此外，在传动件32具有第一预设位置和第二预设位置的实施例中，控制组件能够控制传动件32处于第一预设位置，即传动件32保持复位至初始位置，便于用户对储液容器10进行安装与拆卸。
在一些实施例中，预设阈值大于等于1，具体取值可以根据餐具洗涤效果等实际情况设置，例如预设阈值可以出厂前设置或者由用户自行设置。在一些具体实施例中，预设阈值可以为1、2、3、4、5等。
当然，在驱动组件30包括驱动件31和传动件32的实施例中，位置检测组件70也可以用于检测传动件32的位置，具体地，控制组件设置成在位置检测组件70检测到传动件32移动至第一预设位置时计数并在计数值达到预设阈值时控制驱动件31停止工作，这也在本申请的保护范围之内。
在本申请的一些实施例中，泵头21可以在第一预设位置和第二预设位置之间移动，并且泵头21被构造成由第一预设位置向第二预设位置移动时，将储液容器10内的洗涤液泵出，从而实现洗涤液的投放。在泵头21由第二预设位置向第一预设位置移动时，泵头21可向远离储液容器10的方向移动，以复位。
在一些实施例中，泵体20还可以包括复位件，复位件用于驱动泵头21由第二预设位置向第一预设位置移动，以复位，以保证泵头21可以顺利地往复运动，并且保证泵头21能够每次精准复位至第一预设位置，有利于实现洗涤液投放量的精准控制。
需要说明的是，位置检测组件可以直接检测泵头21的位置，也可以间接检测泵头21的位置，这都可以判断洗涤液的投放量，同样具有投放量控制精准的有益效果。

在一些实施例中，如图6-图8所示，座体50具有用于容纳传动件32的容纳腔54，传动件32安装于容纳腔54内，传动件32包括传动本体，传动本体的一端与驱动件31配合，例如通过配合凹槽321和配合凸部313相配合；传动本体的另一端与泵头21配合，例如通过限位凹槽40和限位凸部41相配合。触发凸部322设于传动本体的外周面，且触发凸部322位于容纳腔54内，微动开关安装于座体50，且微动开关具有触点541，触点541伸入容纳腔54，使触发凸部322可以与触点541接触，以触发微动开关，从而实现对驱动件31的位置检测。

例如，在第三实施例中，位置检测组件70可以包括光电感应器，光电感应器与控制组件相连，光电感应器具有发光端和接收端，接收端用于接收发光端发出的光线。传动件32具有遮挡部，遮挡部在传动件32移动至第一预设位置时，遮挡部遮挡光线，传动件32离开第一预设位置时，接收端能够再次接受发光端发出的光线，控制组件在光线被遮挡时计数。由此，根据接收端被遮挡的次数即可获取传动件32移动至第一预设位置的次数，从而得知传动件32的往复次数，以实现对洗涤液投放量的控制，结构简单，控制效果好。
例如，在第四实施例中，位置检测组件70可以包括霍尔元件与磁性件，霍尔元件与控制组件相连，磁性件设于传动件32，在传动件32移动至第一预设位置时，霍尔元件检测到磁性件并产生脉冲信号，传动件32离开第一预设位置时，霍尔元件无法检测到磁性件，控制组件在霍尔元件产生脉冲信号时计数。由此，根据霍尔元件产生脉冲信号的次数即可获取传动件32移动至第一预设位置的次数，从而得知传动件32的往复次数，以实现对洗涤液投放量的控制，结构简单，控制效果好。
