Description

基于温度响应确定灶具器具上的炊具位置 技术领域
本主题总体上涉及灶具器具，或更具体地涉及用于操作灶具器具的方法。
背景技术
灶具器具通常包括用于加热烹饪用具、比如壶、平底锅和平板炉的加热元件。用户可以选择期望的加热水平，并且修改加热元件的操作以匹配期望的加热水平。例如，某些灶具器具包括电加热元件。在操作期间，这种灶具器具以对应于选择的加热水平的预定功率输出操作电加热元件。作为另一示例，一些灶具器具包括作为加热元件的燃气燃烧器。在这种示例灶具器具的操作中，燃烧器的预定的燃气流量可以对应于所选择的加热水平。
以对应于所选择的加热水平的预定水平(例如，功率输出、燃料流量等)操作加热元件带来了某些挑战。例如，预定水平仅是实际烹饪温度的间接测量。一些灶具器具采用温度传感器来直接测量烹饪用具和/或包含在烹饪用具内的制品的温度。然后可以使用测量到的温度来将加热水平调节到高于或低于预定水平，以便实现更接近选择的加热水平的烹饪温度。
然而，在某些情况下，具有温度传感器的烹饪用具可能被错放。例如，具有温度传感器的烹饪用具可以位于除基于测量到的温度被调节的加热元件之外的加热元件上。此外，具有温度传感器的烹饪用具可以是第一烹饪用具，并且第二烹饪用具可以位于基于第一烹饪用具的测量到的温度被调节的加热元件上。在这种情况下，第一烹饪用具中的制品可能不会根据需要被加热，并且可以将基于测量到的温度被调节的加热元件的功率输出被调节至不适于第二烹饪用具和/或其中的制品的水平，这可能会降低灶具器具的烹饪性能。
相应地，具有用于避免这种降低的烹饪性能的特征的灶具器具将是有用的。 具体而言，具有用于确定或验证具有温度传感器的烹饪用具对应灶具器具的加热元件或正确地位于其上将是特别有益的，其中灶具器具的加热元件基于来自温度传感器的测量值来被控制。

具体实施方式
现在将详细参考本发明的实施例，其一个或更多个示例在附图中示出。提供每个示例是为了解释本发明，而不是限制本发明。实际上，对于本领域技术人员来说显而易见的是，在不背离本发明的范围或精神的情况下，可以在本发明中进行各种修改和变型。例如，作为一个实施例的一部分示出或描述的特征可与另一实施例一起使用，以产生又一实施例。因此，本发明旨在覆盖落入所附权利要求及其等同物的范围内的这些修改和变型。
如本文所使用的，近似术语，比如“大体”或“大约”，包括大于或小于所述值的百分之十以内的值。当在角度或方向的上下文中使用时，这些术语包括比所述角度或方向大10度或小10度内的度数，例如，“大体竖直”包括与竖直方向V在任何方向(例如，顺时针或逆时针)上形成高达10度的角度。
图1提供了包括灶具12的炉灶器具或炉灶10的透视图。炉灶10仅作为示例提供，并且并不旨在将本主题限制于图1中所示的布置。因此，本主题可以与其它炉灶10和/或灶具12、构造(例如，双烤箱炉灶器具、独立灶具器具、 没有烤箱的灶具器具等)一起使用。
灶具器具12的烹饪表面14包括多个加热元件16。对于所示的实施例，灶具12包括沿着烹饪表面14间隔开的五个加热元件16。加热元件16大体定位在烹饪表面14处，例如，在烹饪表面14上或附近。在某些示例性实施例中，灶具12可以是具有电阻加热元件或安装在烹饪表面14下方的线圈的辐射灶具。然而，在其它实施例中，灶具器具12可以包括加热元件16的任何其它合适的形状、构造和/或数量。例如，在各个实施例中，灶具器具12可以包括任何其它合适类型的加热元件16，比如感应加热元件或燃气燃烧器等。加热元件16中的每个可以是相同类型的加热元件16，或者灶具器具12可以包括不同类型的加热元件16的组合。
如图1中所示，烹饪用具18(比如壶、平底锅或类似物)可以放置在加热元件16上，以加热烹饪用具18并烹饪或加热放置在烹饪用具18中的食物物品。炉灶器具10还包括门20，其允许进入炉灶器具10的烹饪室(未示出)，例如用于烹饪或烘烤其中的食物物品。具有控制件24的控制面板22允许用户对食物物品的烹饪作出选择。尽管示出在炉灶器具10的后挡板或后面板26上，控制面板22可以定位在任何合适的位置。控制件24可以包括按钮、旋钮和类似物、以及其组合，和/或控制件24可以在如下所述的比如智能电话等远程用户接口装置上实现。作为示例，用户可以操纵一个或更多个控制件24以针对每个加热元件16选择温度和/或热量或功率输出。选择的加热元件16的温度或热量输出影响传递到放置在加热元件16上的烹饪用具18的热量。
如将在以下以更详细地论述的，灶具器具12包括用于控制多个加热元件16中的一个或更多个的控制系统50(图3)。具体而言，控制系统50可以包括可操作地连接至控制面板22和控制件24的控制器52(图2和3)。控制器52可以可操作地连接至多个加热元件16中的每个，以响应于通过控制面板22和控制件24接收到的一个或更多个用户输入来控制多个加热元件16中的每个的加热水平。
现在参考图2，提供了图1的灶具12的顶部示意图，或更具体地，图1的灶具12的烹饪表面14的顶部示意图。如上所述，对于所示的实施例的灶具12的烹饪表面14包括沿着烹饪表面14间隔开的五个加热元件16。同样示意性地示出的烹饪用具18定位在多个加热元件16的第一加热元件16上。对于所示的实施例，炊具温度传感器28和食物温度传感器30也与烹饪用具18相关联。
在一些示例性实施例中，炊具温度传感器28可以与烹饪用具18接触、附接到烹饪用具18或集成到烹饪用具18中，并且被构造成感测例如烹饪用具18的底表面或烹饪用具18的底壁的温度。例如，炊具温度传感器28可以嵌入烹饪用具18的底壁内，如图3中所示。替代地，炊具温度传感器28可以例如、邻近烹饪用具18的底表面或底壁嵌入在烹饪用具18的侧壁内。
此外，食物温度传感器30可以定位在任何合适的位置，以感测定位在烹饪用具18内的一个或更多个食物物品32(参见图3)的温度。例如，食物温度传感器30可以是探针型温度传感器，其被构造成插入一个或更多个食物物品32中。然而，替代地，食物温度传感器30可以被构造成以任何其它合适的方式确定定位在烹饪用具18内的一个或更多个食物物品的温度。
在某些示例性实施例中，炊具温度传感器28和食物温度传感器30中的一个或两个可以采用任何合适的技术来感测/确定烹饪用具18和/或定位在烹饪用具18中的食物物品32的温度。炊具温度传感器28和食物温度传感器30可以通过接触和/或非接触方法测量相应的温度。例如，炊具温度传感器28和食物温度传感器30中的一个或两个可以采用热电偶、热敏电阻、光学温度传感器、红外温度传感器、电阻温度检测器(RTD)中的一个或更多个。
再次参考图2和3，灶具器具12另外包括至少一个接收器34。在图2所示的示例中，灶具器具12包括多个接收器34，每个接收器34与单独的加热元件16相关联。每个接收器34被构造成接收来自食物温度传感器30的指示定位在烹饪用具18内的一个或更多个食物物品32的温度和/或来自炊具温度传感器28的指示定位在相应的加热元件16上的烹饪用具18的温度的信号。在其它实施 例中，可以提供单个接收器34，并且单个接收器34可以操作性地连接至一个或一个以上的传感器。在至少一些示例性实施例中，炊具温度传感器28和食物温度传感器30中的一个或两个可以包括无线传输能力，或替代地可以例如通过有线通信总线硬连接到接收器34。
图3提供了根据本公开的一示例性实施例的用于操作灶具器具12的系统的示意图。具体而言，图3提供了示例性控制系统50和图1和2的示例性灶具器具12的加热元件16的示意图。
如上所述，灶具器具12包括与加热元件16中的一个或更多个相关联的接收器34，例如多个接收器34中的每个与相应的加热元件16相关联。对于所示的实施例，每个接收器34直接定位在相应的加热元件16的中心部分下方。另外，对于所示的实施例，每个接收器34被构造为无线接收器34，其被构造成接收一个或更多个无线信号。具体而言，对于所示的示例性控制系统50，炊具温度传感器28和食物温度传感器30两者都被构造为经由无线通信网络54与无线接收器34无线通信的无线传感器。在某些示例性实施例中，无线通信网络54可以是无线传感器网络(比如蓝牙通信网络)、无线局域网(WLAN)、点对点通信网络(比如射频识别(RFID)网络、近场通信网络等)、上述通信网络中的两个或更多个的组合、或任何合适的一个或多个无线通信网络。
仍然参考图3，与相应的加热元件16相关联的每个接收器34可操作地连接至控制系统50的控制器52。接收器34可以经由有线通信总线(如图所示)或替代地通过类似于以上讨论的示例性无线通信网络54的无线通信网络可操作地连接至控制器52。控制器52通常可以包括具有一个或更多个处理器58和相关联的存储装置60的计算装置56。计算装置56可以被构造成执行各种计算机实施的功能以控制示例性的灶具器具12。计算装置56可以包括通用计算机或专用计算机，或任何其它合适的计算装置。应当理解的是，如本文所使用的，处理器58可以指控制器、微控制器、微型计算机、可编程逻辑控制器(PLC)、专用集成电路和其它可编程电路。此外，(一个或多个)存储装置60可以大体包括 (一个或多个)存储元件，其包括但不限于计算机可读介质(例如，随机存取存储器(RAM))、计算机可读非易失性介质(例如，闪存存储器)、光盘只读存储器(CD-ROM)、磁光盘(MOD)、数字多功能盘(DVD)、和/或其它适合的存储元件。存储器60可以存储可由(一个或多个)处理器58访问的信息，包括可以由(一个或多个)处理器58执行的指令。例如，指令可以是软件或任何指令集，当由(一个或多个)处理器58执行时，其致使(一个或多个)处理器58执行操作。对于所示的实施例，指令可以包括被构造成操作系统、例如以执行下述的示例性方法的软件包。
仍然参考图3，控制系统50另外包括可操作地连接至控制器52的用户接口62。对于所示的实施例，例如，在图3中，用户接口62被构造为与控制器52有线通信。然而，在其它示例性实施例中，例如，如图2中所示，用户接口62可以附加地或替代地经由一个或更多个合适的无线通信网络(比如上述示例性无线通信网络54)无线地连接至控制器52。在某些示例性实施例中，用户接口62可以被构造为在灶具器具12上的控制面板22和多个控制件24(参见图1)。附加地或替代地，用户接口62可以被构造为外部计算装置或远程用户接口装置，比如智能电话、平板电脑或能够连接至示例性控制系统50的控制器52的其它装置。例如，在一些实施例中，远程用户接口可以是由远程用户接口装置(比如智能电话或平板电脑)执行的应用程序或“app”。响应于经由用户接口62的用户输入通过在控制器52中生成的信号操作灶具12。
此外，控制器52可操作地连接至多个加热元件16中的每个，用于响应于通过用户接口62(例如，控制面板22和控制件24)的一个或更多个用户输入来控制多个加热元件16中的每个的加热水平。在各个实施例中，控制加热元件的加热水平可以包括控制对加热元件的电力供应、向加热元件的燃料供应等。例如，其中加热元件16中的一个或更多个构造为电阻加热器，控制器52可以可操作地连接至控制对这种电阻加热器进行功率供应的相应的继电器。替代地，在其中加热元件16中的一个或更多个被构造为感应加热元件的实施例中，控制 器52可以可操作地连接至相应的电流控制装置。作为另一示例，在其中加热元件16中的一个或更多个被构造为燃气燃烧器的实施例中，控制器52可以可操作地连接至在每个燃气燃烧器的燃料供应管线中的阀和/或这种燃料供应阀的致动器，以控制至相应燃烧器的燃料的供应，例如流量。
现在转到图4，示出了第一烹饪用具18A，其可以包括炊具温度传感器28和食物温度传感器30中的一个或两个，例如，如上述示例中的任何一个或组合。图4中还示出了第二烹饪用具18B。如图4中所示，响应于通过温度传感器28和/或30的测量到的温度而被控制的加热元件可以是第一加热元件16A，并且灶具12还可以包括第二加热元件16B。利用这种示例性灶具12，一个或更多个烹饪用具可能被错放。例如，如图4中所示，第一和第二烹饪用具18A和18B都被错放。第一烹饪用具18A未放置在响应于来自位于第一烹饪用具18A中的温度传感器28和/或30的温度测量值而被控制的第一加热元件16A上，使得预期的响应加热未提供给第一烹饪用具18A和其中的制品。如本文中所使用的并且如本领域通常所理解的那样，在加热元件上的用具紧邻加热元件附近定位，从而足以被加热元件加热，例如，在包括电阻加热元件或燃气燃烧器加热元件的实施例中处于热连通，或在一些实施例中在感应加热元件的磁场内，但用具并不是必须地与加热元件直接物理接触从而位于加热元件上。第二烹饪用具18B也被错放，因为第二烹饪用具18B和其内的制品可以以响应于除了第二烹饪用具18B以及其中任何食物制品32的实际温度之外的温度(例如，由第一用具18A中的传感器28和/或30测量到的温度)的水平被第一加热元件16A加热。
在一些实施例中，控制器52可以被构造成当第一烹饪用具18A位于第一加热元件16A和第二加热元件16B中的一个上时接收来自与第一烹饪用具18A相关联的温度传感器的信号。例如，如上所述，可以经由接收器34从传感器接收到信号。温度传感器可以与烹饪用具18相关联，其中温度传感器(比如炊具温度传感器28)被定位和构造成感测烹饪用具18自身的温度，和/或温度传感器(比如食物温度传感器30)被定位和构造成感测烹饪用具的内容物的温度。为 了确认第一烹饪用具18A位于第一加热元件16A上，控制器52进一步构造成基于经由温度传感器28和/或30测量到的温度响应来确定第一烹饪用具18A的位置。
例如，在一些实施例中，控制器52可以被构造成以第一加热水平(例如以高于第二加热元件16B的加热水平的加热水平)启用第一加热元件一测试时段。在各个实施例中，第二加热元件16B可在测试时段期间停用或以低加热水平启用。第一加热水平可以有利地是对应于用户选择的加热水平的普通加热水平。在这类实施例中，第一烹饪用具18A的位置可以在期望的烹饪操作中以最少的中断或没有中断来确定或确认。控制器52还可以被构造成在测试时段期间监测与第一烹饪用具18A相关联的温度，例如第一烹饪用具18A自身的温度和/或第一烹饪用具18A的内容物的温度。因此，控制器52可以确定：当监测到的温度的值大于预定阈值时，烹饪用具位于第一加热元件上。在各个实施例中，监测到的温度的值可以是监测到的温度的净增加、监测到的温度的增加率和/或监测到的温度的积分中的一个或更多个。例如，监测到的温度的积分可以表示时间/温度曲线下的面积，使得大于预定阈值的监测到的温度的积分表示监测到的温度已达到至少阈值温度和/或保持处于或高于阈值温度一最小时间量。
一旦已确定第一烹饪用具18A与相关联的温度传感器28和/或30位于第一加热元件16A上，控制器52就可以响应于测量到的温度、例如基于从温度传感器28和/或30的接收到的信号调节第一加热元件16A的加热水平来操作第一加热元件16A。在一些实施例中，当监测到的温度的值小于预定阈值时，例如，在测试时段过去之前监测到的温度从未达到预定阈值的情况下，控制器52还可以构造成停用第一加热元件16A。在这种情形下，控制器52可以进一步构造成当监测到的温度的值小于预定阈值时，例如经由用户接口62提供比如错误消息或警告等通知。
如以上提及的，第一加热水平可以有利地是对应于用户选择的加热水平的普通加热水平。一般而言，在测试时段期间以普通水平操作或尽可能接近普通 水平来操作(一个或更多个)加热元件可能是有利的。本领域技术人员将认识到，“普通”加热水平是当每个预期的烹饪用具放置在预期的加热元件上时加热元件被操作的水平。例如，普通加热水平可以是响应于用户选择的加热水平而为烹饪操作设置的加热水平。在这些示例中，控制器52进一步构造为生成温度设定。例如，灶具器具12和/或其控制器52可以被构造成响应于经由用户接口62(图3)接收到的用户输入而生成温度设定。在这些实施例中，在测试时段期间以第一水平启用第一加热元件16A可以包括将第一加热元件16A的加热水平设定为与生成的温度设定相关联的普通水平。在其它实施例中，在测试时段期间第一加热水平还可以或替代地包括基于、例如通过使用闭合控制回路(比如PI或PID控制))测量到的温度的可变加热水平。例如，在测试时段期间第一加热水平可以初始地包括普通水平，其然后可以基于PID控制而被修改或改变。因此，在一些实施例中，普通水平可以包括基于闭合控制回路的输出的被调节的可变水平。
在一些实施例中，对于所述测试时段启用第一加热元件16A可以包括将第一加热元件16A的加热水平设定为对应于用户选择的低设定的普通水平。如已提到的，第二加热元件16B(以及任何附加的加热元件，比如例如图2中示出的第三、第四和第五加热元件)可以在所述测试时段、特别是当针对第一加热元件16A的用户选择的设定是低设定或中设定时被停用。在各个实施例中，可以应用任何合适的加热水平组合，例如，其中加热水平之间的差异大到足以提供可测量的温度响应。
测试时段可以包括足以区分第一烹饪用具18A的测量到的温度响应是否与预期的温度响应对应或不对应的任何合适持续时间。例如，作出进行这种确定的必要时间可以取决于第一加热元件16A的加热水平，例如，当第一加热元件16A以高加热水平操作时，可以更快地确定第一烹饪用具18A未被第一加热元件16A加热。相应地，在各个实施例中，测试时段的持续时间可以对应于第一加热水平，例如，当所生成的温度设定是高设定时，持续时间可以更短。例如， 可以从查询表确定测试时段的持续时间，其中，第一加热水平(例如，生成的温度设定)可以在表中查找以确定测试时段的对应的持续时间。
如本文关于用户选择所使用的，比如“低”、“中”和“高”等术语相对于彼此以及在加热元件的最大可能的热输出或加热水平的上下文下理解。例如，用户可以选择高设定，并且对应的普通加热水平可以包括以其热输出能力的约百分之六十七(67％)或以上(比如约百分之七十五(75％)或更多，比如约百分之八十五(85％)或更多，比如约百分之九十五(95％)或更多)来操作加热元件。在各个实施例中，这种百分比或水平可以对应于功率水平，比如施加到加热元件的所施加的电压或电流，或燃料供应速率。例如，用户可选择的低设定可以对应于约一千八百瓦(1800W)的普通加热水平，用户可选择的中设定可以对应于大约二千五百瓦(2500W)的普通加热水平，并且用户可选择的高设定可以对应于大约三千七百瓦(3700W)的普通加热水平。作为另一示例，在燃气燃烧器的情形下，低设定可以对应于在大约百分之三十三(33％)打开或更小(比如大约百分之十(10％)打开或更小)的燃料供应阀位置情形下的加热水平，中设定可以对应于在大约百分之三十三(33％)和大约百分之七十五(75％)之间打开的阀位置的情形下的加热水平，并且高设定可以对应于在约百分之七十五(75％)打开或更多的阀位置的情形下的加热水平。
在各个实施例中，测试时段的持续时间可以小于约十秒，比如约五秒或更短，比如约三秒或更短。在这些实施例中，可能有利的是为测试时段提供短的持续时间以避免或使在第二加热元件16B(和/或除第一加热元件16A之外的其它加热元件，比如第三、第四加热元件等)上的烹饪操作的破坏最小化。当第二加热元件16B在测试时段期间被停用时，测试时段的短的持续时间(例如，约五秒或更短)可能是特别有利的。另外，在第二加热元件16B被停用的情形下，并且在第一加热元件16A的加热水平与第二加热元件16B的加热水平之间存在大的差异的其它实施例中，测量到的温度的确定值(如果有的话)可以在相对短的时间内达到预定阈值。例如，当在第一加热元件16A的加热水平与第 二加热元件16B的加热水平之间存在大的差异时，可以快速且容易地确定测量到的温度是否更接近地匹配第一加热元件16A上的烹饪用具的温度响应或者第二加热元件16B上的烹饪用具的温度响应。
图5示出了操作灶具器具(比如示例性灶具12)的示例性方法200。在一些实施例中，控制器52可以被构造为执行方法200的一些或所有步骤。方法200可以初始地包括接收信号202，其中从控制面板或多个控制件中的一个或更多个控制件接收信号202。信号202可以指示利用炊具的特定物品(例如第一烹饪用具18A)在特定燃烧器(例如，第一加热元件16A)上执行闭环控制的烹饪操作的意图。方法200还可以包括启用第一加热元件16A一测试时段的步骤204以及停用所有其它加热元件一所述测试时段的步骤205。
方法200还可以包括在测试时段期间例如利用温度传感器监测与烹饪用具相关联的温度的步骤206。可以利用炊具温度传感器28和食物温度传感器30中的一个或两个来监测温度，例如，温度值可以在测试时段内由温度传感器28和/或30连续测量。因此，应该明白的是，本文使用的“监测(monitored)”、“监测(monitoring)”或它的其它同根词包括在一段时间内的连续或重复测量或抽样数据，例如温度。此外，在各个实施例中，在监测步骤(例如，步骤206)中使用的温度传感器可以是炊具温度传感器28和食物温度传感器30中的一个或两个，并且监测到的温度可以是第一烹饪用具18A的温度和食物物品32的温度中的一个或两个。
方法200还可以包括，在步骤208处，确定监测到的温度的值是否大于预定阈值。如果是，则可以确定烹饪用具位于第一加热元件上。在确定烹饪用具位于第一加热元件16A上之后，方法200可以包括基于来自温度传感器的接收到的信号例如通过将温度信号输入到闭合控制回路中并基于控制回路的输出调节加热水平来调节第一加热元件16A的加热水平的步骤210。当监测到的温度的值小于预定阈值时，方法200可以包括停用第一加热元件并提供通知的步骤212。
图6提供了烹饪用具在测试时段内的示例温度响应的曲线图。在一些实施例中，测试时段可以是五秒(5秒，如图6中所示)。图6示出了各个实施例，其中温度响应表示烹饪用具18A位于第一加热元件16A上。如图6中所示，监测到的温度的值可以是测试时段内的温度升高。在各个实施例中，预定阈值可以取决于加热水平。例如，如图6中所示，当加热水平(例如在该实施例中是电阻加热元件的加热元件16A的普通功率水平)被设定为例如对应于用户选择的低设定的功率水平1时，表示烹饪用具18A位于预期的第一加热元件16A上的温度升高是相对小的。图6中还示出了可以对应于用户选择的中设定的功率水平5、以及可以对应于用户选择的高设定的功率水平10。如在图6中可以看到的，当加热水平较高时，预定阈值可以相应地更高。
此书面说明书使用示例来公开本发明，包括最佳模式，并且也使得任何本领域技术人员能够实践本发明，包括制造并使用任何装置或系统以及执行任何所结合的方法。本发明的可专利性范围由权利要求限定，并且可以包括本领域中的技术人员想到的其它示例。如果这些其它示例包括不与权利要求的字面语言不同的结构元件，或者如果这些其它实例包括与权利要求的字面语言无显著差别的等同结构元件，则这些其它实例意图在权利要求的范围内。
