Description

本发明涉及制冰设备领域，尤其涉及一种自动供水装置、具有其的冰箱及自动供水方法。
背景技术
目前，许多冰箱中均可提供冷藏后的饮用水。一般来说有两种供水方式，一种供水方式是在冰箱表面设置分配器，用户可以使用水杯在分配器处接水；另一种供水方式为冰箱内设置水壶，将水壶中装满水后放入冷藏室，过段时间再拿出来即可喝到冷水。在第二种方案中，为了更方便用户可随时取用足量的冷水，市面上出现了一些自动注水装置，利用一组霍尔开关及磁铁来检测水壶是否放置在支架上，再利用另一组霍尔开关及内设磁铁的浮子来检测水壶内液位是否较低，并在水壶放置在支架上且液位较低时自动注水。
然而，一般浮子均可从水壶中拆卸出来，若用户在清洗水壶时忘记将浮子放入水壶，则会导致霍尔开关无法检测到磁铁而一直自动注水直至水溢出水壶。因此，这种检测方式存在溢水隐患，为用户带来很多麻烦。
发明内容
本发明的目的在于提供一种自动供水装置、具有其的冰箱及自动供水方法。

作为本发明的进一步改进，所述注水杯包括向上凸起的底壁，所述出水口在所述周壁上自上而下延伸到连接底壁的位置。

作为本发明的进一步改进，所述挡水板为弧形。
作为本发明的进一步改进，所述挡水板自所述壶盖向所述水壶底部延伸，过水通道形成于挡水板的两侧和底部。
本发明另一方面还公开了一种冰箱，包括箱体及用于开闭所述箱体的门体，所述门体内侧设有如上中任意一项所述的供水装置。
本发明另一方面还公开了一种自动供水方法，用于为设于冰箱门的水壶供水，所述方法包括：检测设于所述水壶内的感应元的实时高度；当所述感应元位于第一高度时，输出第一检测信号；控制器接收到第一检测信号时，打开水阀；控制器接收到第二检测信号时，关闭所述水阀。

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，本发明一实施方式公开了一种冰箱，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。如图2-7所示，自动供水装置包括水壶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3-7所示，所述水壶100包括注水口110。所述检测装置300包括感应元321及设置于所述支架200上的第一传感器322，所述感应元321设于所述水壶100内并随液位而升降，所述第一传感器322检测到所述感应元321位于第一高度时输出第一检测信号。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，所述控制器接收到的所述第一检测信号控制所述水阀打开。所述检测装置还包括检测件，所述检测件能够输出表征所述水壶内液位的第二检测信号，所述控制器接收到所述第二检测信号时控制所述水阀关闭。
本发明公开的自动供水装置，仅在第一传感器322检测到感应元321位于较低的第一高度时，控制器才会控制水阀打开，若用户在清 洗水壶后忘记将感应元放入水壶，则控制器会一直控制水阀关闭，从而不会为水壶自动注水。避免了传感器无法检测到感应元，持续注水而导致水壶溢水的问题。
具体地，在本发明实施方式中，所述检测件为设于所述支架200上的第二传感器323，所述第二传感器323检测到所述感应元321位于所述第二高度时输出所述第二检测信号，所述第二高度大于所述第一高度。第二传感器210用于在注水开始后，确定结束注水的时机。
具体来说，第一高度相对于第二高度较为靠近水壶100底部，也就是感应元321在水壶100内的最低点。可以认为感应元321位于第一高度时，水壶100内的水很少或者没有水，此时需要打开水阀来注水；而第二高度为较为靠近水壶100顶部的一个高度，可以认为感应元321在第二高度时，水壶100内的水较多或处于满水状态，此时需要关闭水阀而停止注水。在水壶100内的液位低于第一高度时，此时水壶100的液位一定低于或等于第一高度，而第一传感器322会检测到感应元而输出第一检测信号，控制器会控制水阀打开而为水壶100注水。在注水过程中，感应元321会随着液位向上移动，而当其到达第二高度时，表示水壶100的液位也到达了第二高度，此时第二传感器323会检测到感应元321而输出第二检测信号，控制器会控制水阀关闭。从而完成了自动注水的过程。
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。
如图3所示，在本发明实施方式中，所述水壶内设有浮子盒131，所述感应元321固设于所述浮子盒131内，所述浮子盒131随液位变化而升降。浮子盒131将感应元321密封在内部，以确保可上下浮动。
具体来说，所述水壶100侧壁设有沿高度方向延伸的轨道132，所述浮子盒131位于所述轨道132内，所述轨道132上设有供水流动的水孔1323。具体来说，沿水壶100的高度方向，水壶100的内部侧壁设有轨道132，轨道包括向水壶内部凸出的外壳1321及由外壳1321围成的内部通道1322，浮子盒131设于内部通道1322内，沿外壳1321侧壁的长度方向开设与内部通道1322连通的水孔1323，从而水壶100内的液体可流入内部通道1322内。内部通道1322的尺寸与浮子盒131的尺寸适配，以使浮子盒131仅能随液位在竖直方向移动。另外，在外壳1321的底壁也开设有水孔，以方便液体进入内部通道1322。外壳1321的顶部设有开口1324及用于密封所述开口1324的密封件1325。在用户清洗水壶时，可将密封件1325取出，则浮子盒131也可以被取出以便清洗。
在另外的实施方式中，也可以设置一个与壶盖固定连接，并从壶盖向下延伸的内盒，将浮子盒设于内盒内部，并使得水壶内液体可流入内盒的内部，以便浮子可随液位上下浮动。
在本发明实施方式中，如图4-5所示，所述第一传感器322及第二传感器323均为霍尔开关，所述感应元321为磁铁。两个霍尔开关 沿高度方向设于支架200上，可以分别检测到磁铁的接近。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随之变化。
第一传感器322设于支架200上对应第一高度的位置，第二传感器323设于支架200上对应第二高度的位置。水壶100放置到支架200上之后，若用户忘记将浮子盒131放回水壶100内，则第一传感器322始终无法检测到感应元321，水阀会持续保持关闭状态，无论水壶100内有没有水，均不会为水壶100自动注水。若水壶100放置到支架200上且浮子盒131在水壶100内，则根据液位的不同，感应元321的高度也不同。若水壶100内的液位等于或低于第一高度，则感应元321位于第一高度，此时感应元321与第一传感器322的距离最为接近，第一传感器322感应到的磁通量达到预设值，则第一传感器322内部的触发器翻转而使得第一传感器322的输出电平状态转换(霍尔开关由断开状态转向连通状态)，则控制器接收到第一检测信号而打开水阀，开始为水壶100自动注水。在注水过程中，液位会上升而带动浮子盒131向上移动，感应元321即磁铁也会靠近第二传感器323，直至水壶100内的液位达到第二高度时，第二传感器323感应到的磁通量也达到预设值，则第二传感器323内部的触发器翻转而使得第二传感器323的输出电平状态转换(霍尔开关由断开状态转向 连通状态)，则控制器会接收到第二检测信号而关闭水阀，自动注水停止。从而，通过两个霍尔开关分别检测磁铁的位置而判断水壶内的液位，控制器可根据不同霍尔开关发送的不同检测信号而控制水阀的打开或关闭，以在需要时而为水壶自动注水。并且，设定为必须要接收到表征感应元位于第一高度的第一检测信号时才打开水阀，可保证此时感应元321已在水壶100内部，而不会发生溢水的问题。
同样地，检测装置320也可以检测水壶100是否放置到支架200上。当控制器接收到第一检测信号时，可以确定此时水壶100已放置到支架200上，并且液位较低而需要自动注水。
在另外的实施方式中，所述第二传感器还可以为光电传感器、电容液位传感器等其他传感器，本发明对此不作限制。光电传感器或电容液位传感器等传感器可以直接检测水壶内的液位，当实时液位达到预设液位时，会触发前述传感器向控制器输出检测信号而使控制器关闭水阀。
在另外的实施方式中，所述检测件也可以为计时器，第一传感器可以为霍尔开关。在注水过程中，感应元会随液位逐渐向上移动，而第一传感器感应到的磁通量会在某一液位时小于预设值，则第一传感器的输出电平状态会再度转换(霍尔开关由连接状态转向断开状态)，则控制器会接收到第一传感器输出的断开信号而控制计时器开始计时，在注水时间达到预设时间(可以为15s，30s等)时，可以控制关闭水阀。由此，可以省去第二传感器，而仅利用第一传感器与感应元及计时器的配合来控制水阀的开闭及自动注水的进程。具体地，可 以根据第一传感器所处的高度、自动注水的速度及水壶的容积来提前计算出预设时间。
如图6-7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100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100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8-10所示，本发明另一方面公开了一种自动供水方法，用于为设于冰箱门的水壶供水，所述方法包括：
S100，检测设于所述水壶100内的感应元321的实时高度。
在本发明实施方式中，感应元321装设在浮子盒131内，并可随液位上下移动。具体地，利用设于支架上的第一传感器322来检测感应元的实时高度。第一传感器322为霍尔开关，感应元321为磁铁。
S200，当所述感应元321位于第一高度时，输出第一检测信号。
感应元321位于第一高度时，距离第一传感器322最近，第一传 感器322感应到的磁通量达到预设值而使第一传感器322内部的触发器翻转，从而第一传感器322向控制器输出第一检测信号。
S300，控制器接收到第一检测信号时，打开水阀。
控制器在接收到第一检测信号时，代表此时水壶100内的液位较低，需要注水，则控制器会打开水阀。
S400，控制器接收到第二检测信号时，关闭所述水阀。
第二检测信号为设于支架200上的第二传感器323输出的信号。第二传感器323可检测水壶100内的液位，当液位到达预设液位时，表示水壶内的水已经足够，可以停止注水。因此，第二传感器323会输出第二检测信号，则控制器接收到第二检测信号时关闭水阀。
进一步地，如图9所示，在步骤S300之后，所述方法还包括：
S310，当所述感应元321位于第二高度时，输出所述第二检测信号，所述第二高度大于所述第一高度。
在本发明实施方式中，第二传感器323为霍尔开关，其高度高于第一传感器322的高度。从而在感应元321靠近第二传感器323时，第二传感器323感应到的磁通量达到预设值而使第二传感器323内部的触发器翻转，从而第二传感器323向控制器输出第二检测信号。
进一步地，所述方法还包括：
S500，控制器接收到溢水信号或者冰箱门打开信号时，关闭所述水阀。
自动供水装置还设有溢水检测装置和冰箱门开闭检测装置。溢水检测装置用于检测水壶内的水是否溢出。冰箱门开闭装置用于检测冰 箱门处于打开状态还是关闭状态。具体来说，若控制器接收到溢水信号，则说明水壶内的水已经满溢，因此需要控制器关闭水阀。若控制器接收到冰箱门打开信号，则用户可能会拿取水壶，此时不宜继续注水，因此控制器也需要关闭水阀。
进一步地，如图10所示，在S300的步骤之后，所述方法还包括：
S320，计时器记录所述水阀的打开时间。
在控制器打开水阀之后，计时器即会开始记录水阀的打开时间。
S321，当所述打开时间超过预设时长时，所述计时器输出超时信号。
一般来说，注水的流速是恒定的。则通过流速乘以注水时间可以算出注水量。为防止检测装置及溢水检测装置失效，自动供水装置还设置了注水超时保护。在注水超过预设时长时，可能会发生溢水现象，则计时器会向控制器输出超时信号。具体地，预设时长可以根据注水的流速、水壶的体积等参数来设计具体的数值。在本发明实施方式中，预设时长可以设置为150秒。
S322，所述控制器接收到超时信号时，关闭所述水阀。
当控制器接收到超时信号时，表示可能会发生溢水现象，则控制器会关闭水阀，以免溢水过多。
本发明公开的自动供水装置，仅在第一传感器检测到感应元位于较低的第一高度时，控制器才会控制水阀打开，若用户在清洗水壶后忘记将感应元放入水壶，则控制器会一直控制水阀关闭，从而不会为 水壶自动注水。避免了传感器无法检测到感应元，持续注水而导致水壶溢水的问题。利用两个霍尔开关及一个磁铁来检测水壶内的液位，结构简单，检测准确度高。通过在水壶内壁设置轨道及浮子盒，可使得磁铁随液位上下移动，通过靠近不同的霍尔开关来输出不同的检测信号，控制器可根据接收到的不同的检测信号来控制水阀的开闭。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。
