然而，这些自动注水装置结构复杂，需要利用多个传感器来分别检测水壶是否放置在支架上以及水阀内液位是否较低，从而成本较高，结构较为复杂。

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
应该理解，本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。
如图1所示，本发明公开了一种冰箱，所述冰箱包括箱体及用于开闭所述箱体的门体1，所述门体1内侧设有自动供水装置2。
如图2-6所示，为本发明第一实施方式公开的自动供水装置。自动供水装置2包括水壶100、用于放置所述水壶100的支架200、检测装置300及用于为所述水壶100供水的供水机构400。箱体可以限定一冷藏室，门体1关闭箱体时，冷藏室内的冷气可冷却水壶100内的水。
当然，自动供水装置的使用场所不限于冰箱，也可以是其他制冷家电，或者咖啡馆等各种场所。在本发明实施方式中，水是液体饮料的统称，包括但不限于纯净水、果汁、牛奶或咖啡等液体饮料。
如图2-3所示，所述水壶100包括注水口110。所述检测装置300包括活动连接于所述支架200的开关及与所述开关配合的传感单元320，所述开关设于所述支架200上对应所述水壶100侧壁的位置。所述供水机构400包括供水管410及设于所述供水管410上的水阀，所述供水管410的出口对应所述水壶100的注水口110。所述自动供水装置还包括控制器，所述传感单元320基于所述开关的运动在连通状态与断开状态之间转换，所述水壶100放置于所述支架 200以触碰所述开关，进而带动所述传感单元320处于连通状态。所述传感单元320在连通状态下向所述控制器发送表征所述水壶100内液位的检测信号，所述控制器根据所述检测信号控制所述水阀打开或关闭。
本发明公开的自动供水装置，通过传感单元320的通断状态来判断水壶100是否放置于支架200上，再通过连通状态下的传感单元320输出表征水壶内液位的检测信号，可利用一个传感单元320同时检测水壶100是否放置于支架200上及水壶100内的液位，从而可在水壶100放置于支架200上且液位较低时控制水阀打开，以为水壶100自动注水，使用户可以方便地随时取用冷水。
优选地，传感单元可以为电容传感器，光电传感器，压力/重量传感器或霍尔传感器等，也可以为另外的传感器，只要可以检测并确定水壶内的液体的存在和/或液位即可。
在本发明实施方式中，将水壶100靠近其顶部的一个高度设定为预设液位，当水壶内的液位达到预设液位时，无需向水壶注水，控制器会控制水阀关闭；而当水壶100内的液位未达到预设液位时，则需要向水壶注水，控制器会控制水阀打开。
具体地，在本发明第一实施方式中，所述传感单元320包括电容传感器，所述电容传感器设于所述支架200上对应所述水壶100侧壁的位置。所述电容传感器在连通状态下检测所述水壶100内的液位，并根据所述液位生成所述检测信号。在本发明实施方式中，电容传感器具体为电容式液位传感器。电容式液位传感器是利用被测介质面的变化引起电容变化的一种变介质型电容器。具体来说，开关及电容传感器设于支架300上对应水壶100的预设液位的高度位置处。当电容传感器处于连通状态时，若水壶100内的液位未达到预设液位，电容传感器仅检测到空气，则控制器接收到第一检测信号而控制水阀打开，此时会为水壶100注水；注水过程中，水壶100内的液位逐渐升高，当液位高于电容传感器所处的位置时，电容传感器能够检测到介质由空气变为水，此时电容值发生改变，控制器会接收到第二检测信号而控制水阀关闭，则自动注水完 成。电容传感器的检测动态范围大、响应速度快，且结构简单成本低。
在本发明实施方式中，所述开关包括与所述支架200转动连接的转动件311，支架200上设有电连接件312，所述电容传感器设于所述转动件311内。将水壶放置于支架上时，水壶100的侧壁会触碰并按压转动件311，使转动件311带动电容传感器转动，电容传感器与所述电连接件312接触以使电容传感器通电，从而可通过电容传感器的通断状态而判断水壶100是否放置于支架200。从而，无需设置另外的传感器，仅利用检测液位的电容传感器即可实现对水壶是否放置于支架进行检测。在另外的实施方式中，也可以将电连接件设于转动件上，而将电容传感器固设于支架上。
在另外的实施方式中，也可以将电容传感器设于水壶上，将电连接件设于支架上，在水壶放置于支架上时，电容传感器可与电连接件接触从而处于连通状态。
具体来说，供水管410可外接用户水源，并且沿冰箱箱体延伸至门体1内。当水阀打开时，外接水源即可通过供水管410为水壶100注水。具体地，在本发明实施方式中，供水管从箱体下部的压机仓，沿箱体延伸并进入门体内侧，水阀可以设于压机仓内的供水管上。当然，在另外的实施方式中，水阀也可以设于其他部分的供水管上。
所述电连接件312为弹性件。当水壶100放置于支架200上时，水壶100的侧壁按压转动件311，电容传感器与电连接件312接触并使得弹性的电连接件312处于压缩状态。而当水壶100从支架200上取下时，电连接件312可释放弹力而使转动件311反向转动，电容传感器不再与电连接件312接触而转换为断开状态。在水壶100从支架200上取出之后，弹性的电连接件312可使得转动件311自动被弹力驱动而转动，从而使电容传感器转换为断开状态，简化了电容传感器的通断状态转换。电连接件312可优选为压簧，如图4所示，支架200上延伸出来三个压簧，分别与传感器上的三个触点相对应。。
所述电容传感器包括至少三个触点，转动件311被按压时，所述至少三个 触点均与所述电连接件312接触。所述至少三个触点包括至少两个电连接触点及至少一个信号连接触点。在本发明实施方式中，如图4所示，电容传感器包括三个触点，其中两个为电连接触点，另外一个为信号连接触点。对应地，支架200上设置了三个电连接件312。当转动件311被按压时，电容传感器的两个电连接触点及一个信号连接触点分别与相对应的电连接件312连通，从而电容传感器处于通电状态。控制器检测到电容传感器处于通电状态之后，则可确定水壶100已放置在支架200上。而信号连接触点用于在电容传感器处于连通状态时向控制器发送表征水壶100内液位的检测信号。
如图5-6所示，所述水壶100还包括壶盖120，壶体130及由所述壶盖120和壶体130限定的储水空间，所述注水口110设置于壶盖120上。所述水壶100还包括自所述注水口110向所述水壶100底部延伸的注水杯140，所述注水杯140的周壁上设有多个与所述储水空间连通的出水口141。设置注水杯140可在注水时减缓水流的流速，降低注水时的噪音，还可以防止水流四处飞溅。
优选地，所述注水杯140包括向上凸起的底壁142，所述出水口141在所述周壁上自上而下延伸到连接底壁142的位置。具体地，注水杯140的周壁上间隔设置多个细条状的出水口141，出水口141在注水杯140的周壁上延伸可使得水能够较快地流入储水空间而不会在注水杯140内聚集。底壁142向上凸起可进一步使得注水杯140内的水不会聚集而均从出水口141流出。
所述壶体130上设有出水嘴131，所述储水空间内临近所述出水嘴131的位置设有挡水板150，所述挡水板150与所述水壶100内壁之间形成连通所述出水嘴131的过水通道151。在用户取用水时，可将水从出水嘴131中倒出。设置挡水板150，可以在用户倒水时防止水流过急而溅出水壶100。
优选地，所述挡水板150优选为弧形。并且，挡水板150的其弧顶朝向与所述出水嘴131相对的水壶100的侧壁突出。弧形挡水板150挡水效果较好，且其弧顶朝向与出水嘴131相对的水壶100侧壁突出，可使得挡水板150与水壶100的侧壁形成有效的过水通道，进一步增强防溅水效果。
在本发明实施方式中，所述挡水板150自所述壶盖120向所述水壶100底部延伸，过水通道151形成于挡水板150的两侧和底部。向水壶100底部延伸的挡水板150可从水壶100较低位置即将水纳入过水通道，从而进一步降低倒水时的流速。
如图1所示，门1上设有瓶座3，在瓶座3上增设有支架200，支架200通过连接件与瓶座3预装在一起，连接件具体可以为卡勾结构，以方便将支架200与瓶座3装卸。在用户无需使用水壶时，也可将水壶100及支架200拆卸，原来放置支架的位置可以继续当做瓶座来使用。供水管410的出口处固定在支架100的上半部分，以便与水壶100的壶盖120上的注水口110对准。水壶100位于瓶座3的下侧，且靠近门把手一侧。水壶可以沿门体宽度方向横向抽出，因此占用冰箱空间较小，不影响冷藏室内搁物架的储物空间。
如图7-10所示，为本发明第二实施方式公开的自动供水装置。与第一实施方式不同的是，所述传感单元320’包括与所述转动件311’配合的传感器321’及设于所述水壶100内并随液位而升降的感应元322’，所述转动件311’设于所述支架200’上对应所述水壶100’顶部的位置。所述传感器321’基于所述开关的运动在连通状态与断开状态之间转换，所述转动件311’带动传感器321’处于连通状态。所述传感器321’在连通状态下检测所述感应元322’的位置以输出表征所述水壶100’内液位的检测信号。所述控制器根据接收到的传感器321’的检测信号控制所述水阀打开或关闭。
在本实施方式中，传感器321’设于所述转动件311’内，水壶100’顶部设有凸块124’，将水壶100’放置于支架200’上时，水壶100’顶部的凸块124’会按压开关并使转动件311’带动传感器321’转动，以使传感器321’通电，从而可通过传感器321’的通断状态而判断水壶100’是否放置于支架200’。在水壶100’内部，由壶盖120’向下延伸设有内盒121’，内盒121’的周壁上设有多个与储水空间连通的水孔，从而水壶100’内的水可流入内盒121’。在内盒121’的内部设有浮子盒122’，感应元322’设于所述浮子盒122’内。具体地，内盒121’卡固于壶盖 120’上，并且内盒121’不随液位而升降，而浮子盒122’则会随液位变化在内盒121’的内部上下移动。通过在水壶100’内设置不随液位移动的内盒121’，可限制浮子盒122’的移动范围及移动方向，保证磁铁仅在需要的高度范围内移动，并仅在水壶100’的高度方向上移动。感应元322’固设于浮子盒122’内并随浮子盒122’而上下移动。浮子盒122’将感应元322’密封在内部，以确保可上下浮动。
具体地，浮子盒122’的外径与内盒121’的内径相匹配，以使浮子盒122’仅能沿内盒121’的高度方向上下移动。内盒121’的内壁上还设有多个自上而下延伸的导向筋1211’，可防止浮子盒122’在上下移动时卡住。浮子盒122’的上表面还设有多个凸起1221’，壶盖120’对应凸起1221’的位置设有排气孔123’。具体来说，当水壶100’内液位上升，而浮子盒122’的上表面与壶盖120’底面接触后，有可能会因虹吸效应而使浮子盒122’在液位下降时无法下落。在浮子盒122’上表面设置凸起1221’并在壶盖100’设置排气孔123’，则可使浮子盒122’的上表面与壶盖100’之间有间隙，避免二者之间产生虹吸效应，从而浮子盒122’的上下移动更加顺畅。
在本发明实施方式中，所述传感器321’为霍尔开关，所述霍尔开关设于所述支架200’上对应所述水壶100’的顶部的位置；所述感应元322’为磁铁。霍尔开关设于壶盖120’上，可以检测到磁铁的接近。具体来说，霍尔开关是一种在霍尔效应原理的基础上，利用集成封装和组装工艺制作而成的有源电磁转换器件，霍尔开关可感应到磁通量的大小，当磁通量达到预设值时，霍尔开关内部的触发器翻转，霍尔开关的输出电平状态也随之翻转，从而可将磁输入信号转化成电信号。而浮子盒122’内的磁铁会随液位上下移动，则霍尔开关检测到的磁通量也会随之变化。在霍尔开关处于连通状态下，控制器接收到信号并确定水壶100’已放置在支架200’上。而若水壶100’内的液位未达到预设液位，磁铁与霍尔开关的距离较远，霍尔开关感应到的磁通量无法使霍尔开关内部的触发器翻转，则控制器会控制水阀打开而为水壶100’注水。在注水过程中，液位会上升而带动浮子盒322’向上移动，磁铁也会靠近霍尔开关，直至水壶100’内的 液位达到预设液位时，霍尔开关感应到的磁通量也达到预设值，则霍尔开关内部的触发器翻转而使霍尔开关的输出电平状态转换，则控制器会控制水阀关闭而停止注水。从而，霍尔开关通过检测磁铁的位置而判断水壶100’内的液位，控制器可根据霍尔开关发送的检测信号而控制水阀的开闭，从而在需要时而为水壶100’自动注水。
本发明第二实施方式中的冰箱门体、供水结构等其他结构均与第一实施方式相同，在此不再赘述。
本发明另一实施方式中还公开了一种自动供水方法。所述方法包括以下步骤：S1，接收表征所述传感单元处于连通状态的信号。S2，判断是否接收到表征水壶内的液位达到预设位置的第一检测信号。S3，若是，则转向步骤S4；若否，则转向步骤S5。S4，控制所述水阀关闭。S5，控制所述水阀打开，同时执行步骤S3。
当水壶被放置到支架上时，水壶侧壁会按压转动件而使传感单元接电而处于连通状态，此时控制器会接收到表征所述传感单元处于连通状态的信号。传感单元会检测水壶内的液位，若水壶内的液位达到预设位置，则传感单元会向控制器发送第一检测信号；反之，传感单元不向控制器发送信号，或者向控制器发送第二检测信号。控制器在未接收到第一信号，或者接收到第二检测信号时，会控制水阀处于开启状态，此时供水管会自动向水壶注水。当水壶内的液位逐渐上升至达到预设位置时，控制器接收到第一信号，则控制器会控制水阀关闭，自动注水结束。从而，利用一个传感器，同时实现了对水壶100是否放置于支架200上的检测及水壶100内的液位的检测，从而可为水壶100自动注水，使用户可以方便地随时取用足量的冷水。
本发明公开的自动供水装置及具有其的冰箱，通过传感单元的通断状态来判断水壶是否放置于支架上，再通过连通状态下的传感单元来检测水壶内的液位，可利用一个传感单元同时检测水壶是否放置于支架上及水壶内的液位，从而可在水壶放置于支架上且液位较低时控制水阀打开，以为水壶自动注水，使 用户可以方便地随时取用冷水。弹性电连接件及转动件的配合可使得水壶是否放置于支架与传感单元的连通状态与断开状态的转换相对应。在水壶内设置注水杯可在注水时减缓水流的流速，降低注水时的噪音，还可以防止水流四处飞溅。注水杯的底壁向上凸起可进一步使得注水杯内的水不会聚集而均从出水口流出。设置挡水板，可以在用户倒水时防止水流过急而溅出水壶。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
