Description

物料存储装置及烹饪器具
本申请要求于2018年4月19日提交中国专利局、申请号为201820556826.X、发明名称为“物料存储装置及烹饪器具”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及厨房电器技术领域，具体而言，涉及一种物料存储装置及包含该物料存储装置的烹饪器具。
背景技术
目前，现有的物料存储装置，有的没有定量下料功能，只能用于简单地物料存储和物料输出，不能满足日益增长的用户要求；有的具有定量下料功能，且基本上采用重量传感器的方式来实现物料称量，但是重量传感器的数量和位置不同，称量结果相差较大，因而此种方式定量下料的误差较大，不够精确，且结构比较复杂。
申请内容
为了解决上述技术问题至少之一，本申请的一个目的在于提供一种物料存储装置。
本申请的另一个目的在于提供一种包括上述物料存储装置的烹饪器具。
为了实现上述目的，本申请第一方面的技术方案提供了一种物料存储装置，包括：储料箱，其底部开设有用于输出物料的排料口；下料叶轮，安装在所述排料口处，并与所述排料口的尺寸相适配，用于把上方的物料向下输送至所述排料口处；驱动机构，与所述下料叶轮相连，用于驱动所述下料叶轮旋转；定量装置，包括与所述下料叶轮同步旋转的触发件、与所述储料箱保持相对静止并与所述触发件相配合的感应件和与所述感应件电连接的微处理器；其中， 在所述下料叶轮旋转的过程中，所述触发件与所述感应件之间的最小距离小于所述感应件的感应距离，所述触发件与所述感应件之间的最大距离大于所述感应件的感应距离，以使所述微处理器能够根据所述感应件感应到所述触发件的次数获得所述下料齿轮的旋转圈数，进而实现定量下料。
本申请第一方面的技术方案提供的物料存储装置，利用下料叶轮来实现物料输出，利用定量装置来检测下料叶轮的旋转圈数，通过控制下料叶轮的旋转圈数即可实现定量下料，相较于现有技术中采用称重传感器的方式，下料误差小，更加精确，从而提高了用户体验。
具体地，由于下料叶轮与排料口的尺寸相适配，因而只有下料叶轮转动时才能够带动物料向下排出，而下料叶轮的尺寸是固定的，故而其相邻的叶片之间能够容纳的物料量也是固定的，因此下料叶轮旋转一周输出的物料量也是固定的，故而通过控制下料叶轮的旋转圈数即可实现定量下料；而定量装置包括触发件、感应件和微处理器，由于触发件与下料叶轮同步旋转，感应件与触发件相对设置配套使用并与储料箱保持相对静止，根据触发件的位置变化实现触发状态(即感应到触发件的状态)与非触发状态(即没有感应到触发件的状态)的切换，微处理器与感应件电连接，根据感应件感应到触发件的次数即可获得触发件的旋转圈数，进而实现定量下料，结构和原理均较为简单，且不受部件数量和位置的影响，因而检测结果准确度高，误差小。
更具体地，由于在下料叶轮旋转的过程中，触发件与下料叶轮同步转动，而感应件保持静止不动，触发件与感应件之间的最小距离小于感应件的感应距离，此时感应件能够感应到触发件，表现为触发状态；而触发件与感应件之间的最大距离大于感应件的感应距离，此时感应件不能感应到触发件，表现为非触发状态。因而当下料叶轮正常运转时，带动触发件周期性地周向旋转，使得感应件会表现为触发和非触发两种状态的周期性变化，则微处理器根据感应件触发状态与非触发状态的切换次数(即感应到触发件的次数)即可获得触发件的旋转圈数，亦即下料叶轮的旋转圈数，进而可以精确得出下料叶轮输出的物料量，进而实现精确地定量下料。
至于感应件感应触发件的方式不受具体限制，可以是接触式感应，即感应件与触发件相接触实现感应，也可以是非接触式感应，即感应件与触发件不接 触即可实现感应。
另外，本申请提供的上述技术方案中的物料存储装置还可以具有如下附加技术特征：
在上述技术方案中，所述触发件为磁体，所述感应件为干簧管。
触发件磁体，感应件为干簧管，由于磁体与下料叶轮同步旋转，干簧管与磁体相对设置配套使用，根据磁体的位置变化实现接通状态与断开状态的切换，微处理器与干簧管电连接，根据干簧管的通断状态切换次数即可获得磁体的旋转圈数，进而实现定量下料；且干簧管与磁体的配合，灵敏度高，检测结果更加准确，并实现了非接触式感应，有利于扩大产品的布局方式。
具体地，由于在下料叶轮旋转的过程中，磁体与干簧管之间的最小距离小于干簧管的感应距离，此时干簧管能够感应到磁体，表现为接通状态(相当于开关闭合)；而磁体与干簧管之间的最大距离大于干簧管的感应距离，此时干簧管不能感应到磁体，表现为断开状态(相当于开关断开)。因而当下料叶轮正常运转时，带动磁体周期性地周向旋转，使得干簧管会表现为接通和断开两种状态的周期性变化，则微处理器根据干簧管通断状态的切换次数即可获得磁体的旋转圈数，亦即下料叶轮的旋转圈数，进而可以精确得出下料叶轮输出的物料量，进而实现精确地定量下料。
在上述技术方案中，所述驱动机构包括：驱动件；和套设在所述驱动件的输出轴上的传动组件，所述传动组件与所述下料叶轮相连，用于带动所述下料叶轮相对所述储料箱旋转。

在上述技术方案中，所述驱动机构位于所述储料箱外侧，所述磁体安装在所述从动齿轮上。
将驱动结构设置在储料箱外侧，既避免了驱动机构占用储料箱的内部空间，从而提高了储料箱的空间利用率，又对驱动机构起到了良好的保护作用，有效避免了物料对驱动机构的正常运转造成影响；由于从动齿轮与下料叶轮同轴连接，因而从动齿轮与下料叶轮同步旋转，则将磁体安装在从动齿轮上，通过检测从动齿轮的旋转圈数即可得到下料叶轮的旋转圈数，且使得磁体位于储料箱外侧，能够防止磁体与流动的物料相接触或者受到物料的撞击导致其位置发生变化甚至发生脱落的情况发生，从而对磁体起到了良好的保护作用，提高了磁体的稳定性，进而提高了定量装置的使用可靠性。
在上述技术方案中，所述从动齿轮上设有安装槽，所述磁体嵌入所述安装槽内。
在从动齿轮上设置安装槽，将磁体嵌入安装槽内，既实现了磁体与从动齿轮之间的固定装配，又能够防止磁体在从动齿轮旋转的过程中与其他结构发生干涉。
在上述技术方案中，所述安装槽靠近所述从动齿轮的边缘部位。
使安装槽靠近从动齿轮的边缘部位，则磁体也靠近从动齿轮的边缘部位，因而其线速度相对较大，这样磁体与干簧管之间的最小距离与最大距离之间相差较大，在保证磁体与干簧管可靠配合的基础上，有利于缩小干簧管与从动齿轮之间的距离，进而减小产品体积。
在上述技术方案中，所述安装槽的入口处设有限位凸起，所述限位凸起与所述磁体相抵靠，以限制所述磁体脱出所述安装槽。
在安装槽的入口处设置限位凸起，使磁体与限位凸起相抵靠，能够有效防止磁体在旋转的过程中脱出安装槽，从而提高了磁体的稳定性和使用可靠性，且结构简单，易于实现。
在上述技术方案中，所述安装槽的入口端设有导向斜面，所述导向斜面与所述限位凸起相对设置。
在安装槽的入口端设置导向斜面，导向斜面能够对磁体的安装过程起到良 好的导向作用，从而提高了磁体的装配效率；同时，导向斜面与限位凸起相对设置，在一定程度上缓解了限位凸起对磁体的安装过程造成的干涉，从而降低了磁体的装配难度，进一步提高了磁体的装配效率。
在上述技术方案中，可选地，所述磁体安装在所述下料叶轮上。
将磁体安装在下料叶轮上，确保了磁体与下料叶轮之间能够同步旋转，因而通过检测磁体的旋转圈数即可直接得到下料叶轮的旋转圈数，使得检测结果更加直观，更加准确。
在上述任一技术方案中，所述干簧管固定在所述储料箱的外壁面上。
将干簧管固定在储料箱的外壁面上，能够将干簧管与储料箱内的物料隔离开来，从而对干簧管起到了良好的保护作用，避免了储料箱内的物料或者下料叶轮等部件对干簧管造成影响，从而有效保证了干簧管的稳定性和使用可靠性。
在上述技术方案中，所述储料箱上设有第一连接孔，所述干簧管上设有第二连接孔，紧固件穿过所述第一连接孔与所述第二连接孔，使所述干簧管与所述储料箱固定连接；和/或，所述储料箱的外壁面与所述干簧管中的一个上设有定位柱，另一个上设有定位孔，所述定位柱插入所述定位孔内。
在储料箱上设置第一连接孔，在干簧管上相应设置第二连接孔，使紧固件(如螺钉)穿过第一连接孔和第二连接孔，即可实现干簧管与储料箱的固定连接，结构简单，且固定牢靠。
在储料箱的外壁面与干簧管中的一个上设置定位柱，另一个上设置定位孔，安装时将定位柱对准定位孔，当定位柱插入定位孔内时，即表明干簧管安装到位，因此定位柱与定位孔的配合对干簧管的装配过程起到了良好的定位作用，有利于提高装配效率；同时，定位柱与定位孔的配合还能够对干簧管起到有效的限位作用，防止干簧管在安装紧固件的过程中或者使用过程中发生晃动等情况，从而进一步提高了装配效率，进一步提高了产品的使用可靠性。

触发件为红外发射器，能够定向发射红外线；感应件为红外接收器，用于接收红外发射器发射的红外线信号，与红外发射器相配合实现了非接触式感应。具体地，由于红外发射器与下料叶轮同步旋转，因而只有当红外发射器旋转至正对红外接收器时，红外接收器才能够接收到红外发射器发射的红外线信号，即：当红外发射器旋转至正对红外接收器的位置时，处于红外接收器的感应距离内，当红外发射器旋转至其他位置时，处于红外接收器的感应距离外，因此，红外发射器旋转一周，红外接收器能够接收到一次红外线信号，故而微处理器根据红外接收器接收到红外线信号的次数(即感应到红外发射器的次数)即可获得红外发射器的旋转圈数(即下料叶轮的旋转圈数)，结构和原理均较为简单，易于实现。
触发件为机械凸起，感应件为微动开关，机械凸起与微动开关相配合，实现了接触式感应，检测结果非常准确。具体地，当触发件旋转至能够接触到微动开关时触发微动开关，使微动开关所在电路导通(或断开)，当触发件旋转脱离微动开关时，微动开关复位使其所在电路断开(或接通)，即：当机械凸起旋转至接触微动开关的位置时，处于微动开关的感应距离内，当机械凸起旋转至其他位置时，处于微动开关的感应距离外，因此，机械凸起旋转一周，微动开关的通断状态切换一次，故而微处理器根据微动开关通断状态的切换次数(即感应到机械凸起的次数)即可获得机械凸起的旋转圈数(即下料叶轮的旋转圈数)，结构和原理也较为简单，易于实现。
在上述任一技术方案中，所述微处理器包括：接收模块、计算模块、判断模块和控制模块，所述接收模块用于接收设定的物料量参数，所述计算模块用于根据所述物料量参数及所述下料叶轮的尺寸计算出所述下料叶轮定量输出物料所需的旋转圈数，所述判断模块用于根据所述感应件感应到所述触发件的次数获得所述下料叶轮的实时旋转圈数并判断所述实时旋转圈数是否达到所述下料叶轮定量输出物料所需的旋转圈数，所述控制模块用于在所述判断模块判定所述实时旋转圈数达到所述下料叶轮定量输出物料所需的旋转圈数时控制所述驱动机构停止运转。
如前所述，由于下料叶轮的尺寸是固定的，故而其旋转一周输出的物料量是固定的，故而通过控制下料叶轮的旋转圈数即可实现定量下料，则使用时用户只需输入所需的物料量(记为Ws)，该物料量以物料量参数的形式被微处理器的接收模块接收，而下料叶轮的尺寸可以内置于微处理器内部或者也由用户手动设置，则计算模块根据下料叶轮的尺寸即可计算出下料叶轮旋转一周输出的物料量(计为Wt)，再结合用户所需的物料量，即可计算出下料叶轮定量输出用户所需的物料量所需的旋转圈数(记为Ns，则Ns＝Ws/Wt)，这样在下料叶轮旋转的过程中，判断模块根据感应件感应到所述触发件的次数获得下料叶轮的实时旋转圈数(记为Nt)，当Nt＝Ns时，控制模块即控制驱动机构停止运动，使得下料叶轮也停止运转，则下料叶轮输出的物料量即为用户所需的物料量Ws，原理简单，控制精确。
在上述任一技术方案中，所述物料存储装置还包括：推送螺杆，设置在所述储料箱的底部，所述推送螺杆的出料部位临近所述排料口，能够在旋转时沿其轴向将物料推送至所述排料口处；其中，所述下料叶轮与所述推送螺杆同轴连接，所述推送螺杆的一端连接至所述储料箱的侧壁，另一端穿过所述储料箱的侧壁与所述驱动机构相连。
利用推送螺杆将物料主动推向排料口处进行外排，既可以实现储料箱内的物料无局部残留，从而避免残留的物料变质引起储料箱内物料整体质量下降的问题；又可以优先将位于储料箱底部保存时间较长的物料排出，实现根据时间顺序对储料箱内的物料进行更新，提升储料箱内物料的整体质量；且螺杆驱动具有平稳、连续的优点，可以实现连续下料，有利于后续过程中对下料量进行检测；同时，推送螺杆与下料叶轮相配合，实现了从水平方向与纵向方向分别向排料口输送物料，与单独设置下料叶轮的结构相比，输送效率更高；此外，下料叶轮与推送螺杆同轴连接，因而同步旋转，则驱动机构与推送螺杆相连即可实现对下料叶轮和推送螺杆的同步驱动，从而节省了一套驱动装置，简化了产品结构。
本申请第二方面的技术方案提供了一种烹饪器具，包括：烹饪主体；和如第一方面技术方案中任一项所述的物料存储装置，其排料口能够与所述烹饪主体的内部空间相连通。

在上述技术方案中，所述烹饪器具为电饭煲。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图9描述根据本申请一些实施例所述的物料存储装置及烹饪器具。
如图1至图9所示，本申请第一方面的实施例提供的物料存储装置，包括：储料箱10、下料叶轮20、驱动机构30和定量装置。
具体地，储料箱10的底部开设有用于输出物料的排料口；下料叶轮20安装在排料口处，并与排料口的尺寸相适配，用于把上方的物料向下输送至排料口处；驱动机构30与下料叶轮20相连，用于驱动下料叶轮20旋转；定量装置包括与下料叶轮20同步旋转的触发件、与储料箱10保持相对静止并与触发件相配合的感应件和与感应件电连接的微处理器；其中，在下料叶轮20旋转的过程中，触发件与感应件之间的最小距离小于感应件的感应距离，触发件与感应件之间的最大距离大于感应件的感应距离，以使微处理器能够根据感应件感应到触发件的次数获得下料齿轮的旋转圈数，进而实现定量下料。
本申请第一方面的实施例提供的物料存储装置，利用下料叶轮20来实现物料输出，利用定量装置来检测下料叶轮20的旋转圈数，通过控制下料叶轮20的旋转圈数即可实现定量下料，相较于现有技术中采用称重传感器的方式，下料误差小，更加精确，从而提高了用户体验。
具体地，由于下料叶轮20与排料口的尺寸相适配，因而只有下料叶轮20转动时才能够带动物料向下排出，而下料叶轮20的尺寸是固定的，故而其相邻的叶片之间能够容纳的物料量也是固定的，因此下料叶轮20旋转一周输出的物料量也是固定的，故而通过控制下料叶轮20的旋转圈数即可实现定量下料；而定量装置包括触发件、感应件和微处理器，由于触发件与下料叶轮20同步旋转，感应件与触发件相对设置配套使用并与储料箱10保持相对静止， 根据触发件的位置变化实现触发状态(即感应到触发件的状态)与非触发状态(即没有感应到触发件的状态)的切换，微处理器与感应件电连接，根据感应件感应到触发件的次数即可获得触发件的旋转圈数，进而实现定量下料，结构和原理均较为简单，且不受部件数量和位置的影响，因而检测结果准确度高，误差小。
更具体地，由于在下料叶轮20旋转的过程中，触发件与下料叶轮20同步转动，而感应件保持静止不动，触发件与感应件之间的最小距离小于感应件的感应距离，此时感应件能够感应到触发件，表现为触发状态；而触发件与感应件之间的最大距离大于感应件的感应距离，此时感应件不能感应到触发件，表现为非触发状态。因而当下料叶轮20正常运转时，带动触发件周期性地周向旋转，使得感应件会表现为触发和非触发两种状态的周期性变化，则微处理器根据感应件触发状态与非触发状态的切换次数(即感应到触发件的次数)即可获得触发件的旋转圈数，亦即下料叶轮20的旋转圈数，进而可以精确得出下料叶轮20输出的物料量，进而实现精确地定量下料。
至于感应件感应触发件的方式不受具体限制，可以是接触式感应，即感应件与触发件相接触实现感应，也可以是非接触式感应，即感应件与触发件不接触即可实现感应。
下面结合一些实施例来详细描述本申请提供的上盖组件的具体结构。
实施例一(如图1至图9所示)
触发件为磁体40，感应件为干簧管50，如图1、图2和图7所示。
触发件磁体40，感应件为干簧管50，由于磁体40与下料叶轮20同步旋转，干簧管50与磁体40相对设置配套使用，根据磁体40的位置变化实现接通状态与断开状态的切换，微处理器与干簧管50电连接，根据干簧管50的通断状态切换次数即可获得磁体40的旋转圈数，进而实现定量下料；且干簧管50与磁体40的配合，灵敏度高，检测结果更加准确，并实现了非接触式感应，有利于扩大产品的布局方式。
更具体地，由于在下料叶轮20旋转的过程中，磁体40与干簧管50之间的最小距离小于干簧管50的感应距离，此时干簧管50能够感应到磁体40，表现为接通状态(相当于开关闭合)；而磁体40与干簧管50之间的最大距离 大于干簧管50的感应距离，此时干簧管50不能感应到磁体40，表现为断开状态(相当于开关断开)。因而当下料叶轮20正常运转时，带动磁体40周期性地周向旋转，使得干簧管50会表现为接通和断开两种状态的周期性变化，则微处理器根据干簧管50通断状态的切换次数即可获得磁体40的旋转圈数，亦即下料叶轮20的旋转圈数，进而可以精确得出下料叶轮20输出的物料量，进而实现精确地定量下料。
进一步地，驱动机构30包括：驱动件和套设在驱动件的输出轴上的传动组件，传动组件与下料叶轮20相连，用于带动下料叶轮20相对储料箱10旋转。
其中，传动组件包括套设在驱动件的输出轴上的主动齿轮32和与主动齿轮32相啮合的从动齿轮33，从动齿轮33与下料叶轮20同轴连接，如图1、图3、图4、图5和图7所示。
驱动机构30包括驱动件和传动组件，驱动件(如电机31)作为动力源，为下料叶轮20的旋转提供动力；传动组件套设在驱动件的输出轴上并与下料叶轮20相连，将驱动件的动力传递至下料叶轮20，以带动下料叶轮20旋转。
具体地，传动组件包括主动齿轮32和从动齿轮33，主动齿轮32套设在驱动件(如电机31)的输出轴上，并与从动齿轮33相啮合，将驱动件的动力传递至下料叶轮20，利用齿轮机构实现动力传递，具有传动效率高且稳定可靠的优点；同时，便于根据产品的结构合理布置驱动件的位置，以优化产品的结构和布局。
进一步地，驱动机构30位于储料箱10外侧，磁体40安装在从动齿轮33上，如图2和图8所示。
将驱动结构设置在储料箱10外侧，既避免了驱动机构30占用储料箱10的内部空间，从而提高了储料箱10的空间利用率，又对驱动机构30起到了良好的保护作用，有效避免了物料对驱动机构30的正常运转造成影响；由于从动齿轮33与下料叶轮20同轴连接，因而从动齿轮33与下料叶轮20同步旋转，则将磁体40安装在从动齿轮33上，通过检测从动齿轮33的旋转圈数即可得到下料叶轮20的旋转圈数，且使得磁体40位于储料箱10外侧，能够防止磁体40与流动的物料相接触或者受到物料的撞击导致其位置发生变化甚至发生 脱落的情况发生，从而对磁体40起到了良好的保护作用，提高了磁体40的稳定性，进而提高了定量装置的使用可靠性。
进一步地，从动齿轮33上设有安装槽331，磁体40嵌入安装槽331内，如图2和图8所示。
在从动齿轮33上设置安装槽331，将磁体40嵌入安装槽331内，既实现了磁体40与从动齿轮33之间的固定装配，又能够防止磁体40在从动齿轮33旋转的过程中与其他结构发生干涉。
优选地，安装槽331靠近从动齿轮33的边缘部位，如图2和图8所示。
使安装槽331靠近从动齿轮33的边缘部位，则磁体40也靠近从动齿轮33的边缘部位，因而其线速度相对较大，这样磁体40与干簧管50之间的最小距离与最大距离之间相差较大，在保证磁体40与干簧管50可靠配合的基础上，有利于缩小干簧管50与从动齿轮33之间的距离，进而减小产品体积。
进一步地，安装槽331的入口处设有限位凸起332，限位凸起332与磁体40相抵靠，如图2和图8所示，以限制磁体40脱出安装槽331。
在安装槽331的入口处设置限位凸起332，使磁体40与限位凸起332相抵靠，能够有效防止磁体40在旋转的过程中脱出安装槽331，从而提高了磁体40的稳定性和使用可靠性，且结构简单，易于实现。
优选地，安装槽331的入口端设有导向斜面333，导向斜面333与限位凸起332相对设置，如图2和图8所示。
在安装槽331的入口端设置导向斜面333，导向斜面333能够对磁体40的安装过程起到良好的导向作用，从而提高了磁体40的装配效率；同时，导向斜面333与限位凸起332相对设置，在一定程度上缓解了限位凸起332对磁体40的安装过程造成的干涉，从而降低了磁体40的装配难度，进一步提高了磁体40的装配效率。
进一步地，干簧管50固定在储料箱10的外壁面上，如图1和图3所示。
将干簧管50固定在储料箱10的外壁面上，能够将干簧管50与储料箱10内的物料隔离开来，从而对干簧管50起到了良好的保护作用，避免了储料箱10内的物料或者下料叶轮20等部件对干簧管50造成影响，从而有效保证了干簧管50的稳定性和使用可靠性。
进一步地，储料箱10上设有第一连接孔，干簧管50上设有第二连接孔，紧固件穿过第一连接孔与第二连接孔，使干簧管50与储料箱10固定连接，如图1、图2、图4和图7所示。
在储料箱10上设置第一连接孔，在干簧管50上相应设置第二连接孔，使紧固件(如螺钉60)穿过第一连接孔和第二连接孔，即可实现干簧管50与储料箱10的固定连接，结构简单，且固定牢靠。
进一步地，储料箱10的外壁面与干簧管50中的一个上设有定位柱11，另一个上设有定位孔51，定位柱11插入定位孔51内，如图2所示。
在储料箱10的外壁面与干簧管50中的一个上设置定位柱11，另一个上设置定位孔51，安装时将定位柱11对准定位孔51，当定位柱11插入定位孔51内时，即表明干簧管50安装到位，因此定位柱11与定位孔51的配合对干簧管50的装配过程起到了良好的定位作用，有利于提高装配效率；同时，定位柱11与定位孔51的配合还能够对干簧管50起到有效的限位作用，防止干簧管50在安装紧固件的过程中或者使用过程中发生晃动等情况，从而进一步提高了装配效率，进一步提高了产品的使用可靠性。
优选地，磁体40为永磁体40。
磁体40为永磁体40，如天然矿石(磁铁矿)或人造磁体40(铝镍钴合金)等，永磁体40能够较长期保持其磁性，不易失磁，也不易被磁化，从而保证了故障检测机构具有良好的使用可靠性，且具有较长的使用寿命。
实施例二(图中未示出)
与实施例一的区别在于：磁体40安装在下料叶轮20上。
将磁体40安装在下料叶轮20上，确保了磁体40与下料叶轮20之间能够同步旋转，因而通过检测磁体40的旋转圈数即可直接得到下料叶轮20的旋转圈数，使得检测结果更加直观，更加准确。
至于干簧管50，优选安装在储料箱10的外壁面上，只要储料箱10的材质不会影响磁体40的磁场，保证干簧管50能够感应到磁体40即可。
实施例三(图中未示出)
触发件为红外发射器，感应件为红外接收器。
触发件为红外发射器，能够定向发射红外线；感应件为红外接收器，用于 接收红外发射器发射的红外线信号，与红外发射器相配合实现了非接触式感应。具体地，由于红外发射器与下料叶轮20同步旋转，因而只有当红外发射器旋转至正对红外接收器时，红外接收器才能够接收到红外发射器发射的红外线信号，即：当红外发射器旋转至正对红外接收器的位置时，处于红外接收器的感应距离内，当红外发射器旋转至其他位置时，处于红外接收器的感应距离外，因此，红外发射器旋转一周，红外接收器能够接收到一次红外线信号，故而微处理器根据红外接收器接收到红外线信号的次数(即感应到红外发射器的次数)即可获得红外发射器的旋转圈数(即下料叶轮20的旋转圈数)，结构和原理均较为简单，易于实现。
优选地，红外发射器安装在从动齿轮33上，红外接收器安装在储料箱10的外壁面上。
实施例四(图中未示出)
触发件为机械凸起，感应件为微动开关。
触发件为机械凸起，感应件为微动开关，机械凸起与微动开关相配合，实现了接触式感应，检测结果非常准确。具体地，当触发件旋转至能够接触到微动开关时触发微动开关，使微动开关所在电路导通(或断开)，当触发件旋转脱离微动开关时，微动开关复位使其所在电路断开(或接通)，即：当机械凸起旋转至接触微动开关的位置时，处于微动开关的感应距离内，当机械凸起旋转至其他位置时，处于微动开关的感应距离外，因此，机械凸起旋转一周，微动开关的通断状态切换一次，故而微处理器根据微动开关通断状态的切换次数(即感应到机械凸起的次数)即可获得机械凸起的旋转圈数(即下料叶轮20的旋转圈数)，结构和原理也较为简单，易于实现。
优选地，机械凸起设置在从动齿轮33上，微动开关安装在储料箱10的外壁面上。
在上述任一实施例中，微处理器包括：接收模块、计算模块、判断模块和控制模块，接收模块用于接收设定的物料量参数，计算模块用于根据物料量参数及下料叶轮20的尺寸计算出下料叶轮20定量输出物料所需的旋转圈数，判断模块用于根据感应件感应到触发件的次数获得下料叶轮20的实时旋转圈数并判断实时旋转圈数是否达到下料叶轮20定量输出物料所需的旋转圈数，控 制模块用于在判断模块判定实时旋转圈数达到下料叶轮20定量输出物料所需的旋转圈数时控制驱动机构30停止运转。
如前，由于下料叶轮20的尺寸是固定的，故而其旋转一周输出的物料量是固定的，故而通过控制下料叶轮20的旋转圈数即可实现定量下料，则使用时用户只需输入所需的物料量(记为Ws)，该物料量以物料量参数的形式被微处理器的接收模块(如控制面板或接收器)接收，而下料叶轮20的尺寸可以内置于微处理器内部或者也由用户手动设置，则计算模块(如运算器)根据下料叶轮20的尺寸即可计算出下料叶轮20旋转一周输出的物料量(计为Wt)，再结合用户所需的物料量，即可计算出下料叶轮20定量输出用户所需的物料量所需的旋转圈数(记为Ns，则Ns＝Ws/Wt)，这样在下料叶轮20旋转的过程中，判断模块(如比较器)根据感应件感应到触发件的次数获得下料叶轮20的实时旋转圈数(记为Nt)，并判断Nt是否达到Ns，当Nt＝Ns时，控制模块(如执行器)即控制驱动机构30停止运动，使得下料叶轮20也停止运转，则下料叶轮20输出的物料量即为用户所需的物料量Ws，原理简单，控制精确。
在上述任一实施例中，物料存储装置还包括：推送螺杆70，如图5和图7所示，设置在储料箱10的底部，推送螺杆70的出料部位临近排料口，能够在旋转时沿其轴向将物料推送至排料口处；其中，下料叶轮20与推送螺杆70同轴连接，推送螺杆70的一端连接至储料箱10的侧壁，另一端穿过储料箱10的侧壁与驱动机构30相连。
利用推送螺杆70将物料主动推向排料口处进行外排，既可以实现储料箱10内的物料无局部残留，从而避免残留的物料变质引起储料箱10内物料整体质量下降的问题；又可以优先将位于储料箱10底部保存时间较长的物料排出，实现根据时间顺序对储料箱10内的物料进行更新，提升储料箱10内物料的整体质量；且螺杆驱动具有平稳、连续的优点，可以实现连续下料，有利于后续过程中对下料量进行检测；同时，推送螺杆70与下料叶轮20相配合，实现了从水平方向与纵向方向分别向排料口输送物料，与单独设置下料叶轮20的结构相比，输送效率更高；此外，下料叶轮20与推送螺杆70同轴连接，因而同步旋转，则驱动机构30与推送螺杆70相连即可实现对下料叶轮20和推送螺杆70的同步驱动，从而节省了一套驱动装置，简化了产品结构。
进一步地，推送螺杆70包括：第一螺杆71、第二螺杆72和连接轴73，如图5和图7所示。其中，第一螺杆71的一端连接至储料箱10的一侧内壁，其另一端临近排料口设置；第二螺杆72与第一螺杆71共轴设置，且与第一螺杆71的螺纹设置方向相反，其一端连接至储料箱10的另一侧内壁，其另一端临近排料口设置；连接轴73对应设置在排料口的上方，分别固定连接至第一螺杆71的另一端与第二螺杆72的另一端，以使第一螺杆71与第二螺杆72同步旋转。
在该实施例中，推送螺杆70由第一螺杆71、连接轴73以及第二螺杆72依次固定连接形成，则连接轴73所在的区域即为推送螺杆70的出料部位，便于将推送螺杆70的出料部位及储料箱10的排料口设置在中间区域，进一步提高给料均匀性；并且第一螺杆71与第二螺杆72设置有反向的螺纹，使得第一螺杆71和第二螺杆72可以共用同一驱动装置驱动，且在旋转过程中能够分别同步将外侧端的物料推送至排料口，有效节省电机31用量，精简产品组成部件，降低产品成本；且形成了双向螺旋卸料系统，相对于传统米仓通过斜度利用重力实现物料外排的方案而言，可以实现储料箱10内的物料无局部残留，从而避免残留的物料变质引起储料箱10内物料整体质量下降的问题；此外，通过利用推料螺杆将位于储料箱10内底部位置处的物料推至排料口处进行外排，可以优先将位于储料箱10底部的保存时间较长的物料排出，如此实现根据时间顺序对储料箱10内的物料进行更新，提升储料箱10内物料的整体质量。其中，第一螺杆71、第二螺杆72与连接轴73可以通过固定组装生成，也可以通过一体成型的方式制成。
其中，下料叶轮20套设在连接轴73上，如图7所示，以与推送螺杆70同步转动。
本申请第二方面的实施例提供的烹饪器具，包括：烹饪主体(图中未示出)和如第一方面实施例中任一项的物料存储装置，其排料口能够与烹饪主体的内部空间相连通。
本申请第二方面的实施例提供的烹饪器具，因包括第一方面实施例中任一项的物料存储装置，因而具有上述任一实施例所具有的一切有益效果，在此不再赘述。
至于烹饪主体的内部空间，不受具体限制，比如：可以是上盖内的清洗腔体，物料送入清洗腔体内进行清洗；也可以是内锅，物料送入内锅中进行清洗或者烹饪。
在上述实施例中，烹饪器具为电饭煲。
当然，不局限于电饭煲，也可以为电压力锅、电蒸锅、电煮锅、豆浆机等。
下面结合一个具体实施例来详细描述本申请提供的烹饪器具的结构及工作原理，并与现有技术进行对比。
一种全自动电饭煲，包括：米箱(即储料箱10)、干簧管50、磁铁、从动齿轮33、主动齿轮32、电机31、量米齿轮(即下料叶轮20)、左送米螺杆(即第一螺杆71)、右送米螺杆(即第二螺杆72)。其中，主动齿轮32由电机31带动，主动齿轮32带动从动齿轮33和同从动齿轮33同轴的量米齿轮、左右送米螺杆将米向米箱中间量米齿轮的位置输送。电机31的转动和停止受系统的控制，转动时间的长短根据设定需要的米量，换算为量米齿轮需要转动的圈数来进行控制。
现有技术中的量米模式，基本采用重量传感器的方式，称量米量。在米箱出米的过程中，传感器不断测量米箱中的米量，输出的米量达到设定要求后，操作出米机构停止出米。该方式电子控制系统复杂，米箱的称重结构也复杂。
而本申请的全自动的电饭煲自动称量米量时，采用齿轮旋转的方式，利用齿轮的齿空间作为米量的体积计量单位，为了精确的控制米量的计量，必须准确地测量出齿轮在计量米体积的过程中所转动的齿数或齿轮旋转的圈数。本申请中，采用了磁铁—干簧管50组合作用的方式，与量米齿轮同轴的从动齿轮33上设置有磁铁，该齿轮旁安装有干簧管50，齿轮每转动一圈，干簧管50通断一次，控制系统通过统计干簧管50的通断次数，即可以精确统计计量齿轮(即下料叶轮20)的圈数，从而达到准确称量米量的目的。通过控制量米齿轮的空间大小，就可以控制最小称量米量的值。
综上所述，本申请提供的物料存储装置，利用下料叶轮来实现物料输出，利用定量装置来检测下料叶轮的旋转圈数，通过控制下料叶轮的旋转圈数即可实现定量下料，相较于现有技术中采用称重传感器的方式，下料误差小，更加精确，从而提高了用户体验。
