具体实施方式
下面详细描述本申请实施例，所述实施例的示例性在附图中示出，其中自始至终相同或者类似的标号表示相同或者类型元件或具有相同或类型功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
为了便于理解本申请实施例，以下以电磁炉为例先对相关技术中的电磁加热技术和无线输电技术进行简单的介绍。
电磁炉又称为电磁灶，分为工频(低频)和高频两种，其工作原理是 采用电磁感应原理将电能转换为热能以加热锅具内的食物。以高频电磁炉为例，其具体的工作原理如下：首先利用整流电路将50/60Hz的交流电转换成直流电，然后利用控制电路将直流电转换成频率为20～35KHz高频信号，进而使高速变化的电流流过线圈产生高速变化的磁场，由此，磁场内的磁力线通过金属锅具底部时，在金属体内产生无数小涡流，使锅具本身自行高速发热，进而加热锅具内事物，达到用户使用的结果。
电能的输送是电力系统中发电和用电的中间环节，无线输电作为一种特殊的输电方式，其根据原理不同可分为四大类：电磁感应原理类、谐振式无线输电类、磁耦合共振类及微波无线输电类，通过采用上述四种类型之一可实现电源与受电设备之间不需要物理连接而进行能量耦合，即在物体之间能够传输能量。采用无线输电方式，只要将受电设备放置在指定位置即可，此受电设备与无线输电设备(比如，电磁炉)具备相同的无线充电标准，比如，电源事物联盟(PMA，Power Matters Alliance)标准、Qi标准或无线充电联盟(A4WP，Alliance for Wireless Power)标准等。
电磁加热技术和无线输电技术均采用能量耦合的方式，基于此相关技术中出现了具有电磁加热功能和无线输电功能的电器。但是，目前，电器还不能智能识别放置的负载类型，而是需要用户选择设置负载的类型，但是用户选择负载类型错误，可能会导致电器不能正常工作，甚至损坏电器。因此，本申请实施例期望提供一种检测方案，能够对放置在电器上的负载类型进行智能识别，使得电器基于识别的负载类型工作在相应的工作模式。
下面结合附图来详细描述本申请实施例提出的检测电路、电器及控制方法。
图1为本申请实施例提供的一种检测电路的结构示意图；如图1所示，所述检测电路10至少包括：第一容性组件101、第二容性组件102、待检测负载103和检测组件104，其中：
所述第一容性组件101和所述待检测负载103串联组成第一支路；所述第一支路与包含所述第二容性组件102的第二支路并联；
所述检测组件104，配置为检测所述第一支路的第一交流信号和所述第二支路的第二交流信号，确定所述第一交流信号的第一方向以及所述第二交流信号的第二方向，基于所述第一方向和所述第二方向确定所述待检测负载的类型。
本实施例中，容性组件(包括第一容性组件101和第二容性组件102)指的是具有电容参数的组件，即符合电压滞后电流特性的组件。
本实施例中，第一容性组件可具有多种形式，只要使得第一容性组件呈容性、且满足检测电路的需求即可。一种可选的实施方式是，第一容性组件101可包括第一电容。另一种可选的实施方式是，所述第一容性组件101可包括第一电容和以下至少之一：第一电感、第一电阻；所述第一电容与第一电感、第一电阻中的至少之一串联。相似的，第二容性组件102也可具有多种形式，一种可选的实施方式是，第二容性组件102可包括第二电容；另一种可选的实施方式是，第二容性组件102可包括第二电容和以下至少之一：第二电感、第二电阻；所述第二电容与第二电感、第二电阻中的至少之一串联。应该理解，此处的“第一”、“第二”仅是为了区分后续的描述，没有限制作用。
应该理解，由于第一支路与第二支路并联，则第一支路与第二支路两端的电压值理论上相等，因此，本实施例中的第一交流信号的第一方向是指第一支路上第一交流信号的电流方向；第二交流信号的第二方向是指第二支路上的第二交流信号的电流方向。
在实际应用中，待检测负载的类型可包括输电负载和加热负载两种类型，其中，输电负载可以理解为受电设备，即通过无线输电技术获得电能的设备；加热负载为通过电磁感应原理获得电能转换的热能的设备。示例 性的，输电负载对应的手电设备可以是具有无线充电功能的终端设备，例如手机等。加热负载可以是能够用于电磁加热的锅具等等。
示例性的，在检测到第一支路上的第一交流信号的电流方向与第二支路上的第二交流信号的电流方向之间的夹角接近90°的情况下，可确定所述待检测负载为输电负载；在检测到第一支路上的第一交流信号的电流方向与第二支路上的第二交流信号的电流方向之间的夹角不接近90°的情况下，确定所述待检测负载类型为加热负载。
因此，在本申请的一些可选实施例中，在利用上述检测电路10判断待检测负载的类型时，所述检测组件104，配置为检测所述第一方向和所述第二方向之间的夹角是否在第一预设范围内；在检测到所述第一方向和所述第二方向之间的夹角在所述第一预设范围内的情况下，确定所述待检测负载的类型为输电负载；在检测到所述第一方向和所述第二方向之间的夹角不在第一预设范围内的情况下，确定所述待检测负载的类型为加热负载。
其中，第一预设范围可根据需要进行设定，本实施例中对此可做限定。
例如，第一预设范围为(80°，100°)，表示大于80°小于100°的范围。在检测到第一支路上的电流信号的第一方向与第二支路上的电流信号的第二方向之间的夹角在(80°，100°)的情况下，例如第一方向和第二方向之间的夹角为85°，则待检测负载就可判定为输电负载；在检测到第一支路上的电流信号的第一方向与第二支路上的电流信号的第二方向之间的夹角不在(80°，100°)之间，例如第一方向和第二方向之间的夹角为75°，则待检测负载就可判定为加热负载。
基于与上述相似的申请构思，对于待检测负载类型的判断，如图2所示，本申请实施例还提供了另一种检测电路10的结构示意图，所述检测电路10还可包括：包含感性组件105的第三支路；其中，所述第三支路的一端与交流电源连接；所述第三支路分别与第一支路、第二支路串联；所述 第三支路的第三交流信号包括所述第一交流信号和所述第二交流信号；所述感性组件105配置为对所述交流电源输出的交流信号进行滤波或补偿处理。可以理解，所述第三支路的一端接入交流电源；所述第三支路的另一端分别于所述第一支路和所述第二支路的一端连接。
本实施例中，感性组件105指的是具有电感参数的组件，即负载电流滞后负载电压一个相位差特性的组件。
本实施例中，感性组件105的可具有多种形式，只要满足感性组件的特性即可。基于此，在一种可选的实施方式中，感性组件105可包括第三电感。在另一种可选的实施方式中，感性组件105可包括第三电感和以下至少之一：第三电容、第三电阻；所述第三电感与第三电容、第三电阻中的至少之一串联。
需要说明的是，第三支路位于交流电源侧，且分别与第一支路及第二支路具有相同的节点，根据基尔霍夫定律(Kirchhoff laws)，在一个电路节点中，流出的电流信号等于流入的电流信号，即第三支路中的第三交流信号的电流等于第一支路的第一交流信号的电流与第二支路中的第二交流信号的电流之和。
本申请实施例利用感性组件105对交流电源输出的交流信号进行滤波或补偿处理。本实施例中的交流电源的类型不限，只要能够为检测电路10提供交流信号即可，在此可不做限制，在实际应用中，示例性的，可采用逆变桥式电路的输出的交流信号作为交流电源；应该理解，此交流信号包括交流电压和交流电流等物理量，并且在经过逆变桥式电路输出的交流信号大多是方波，含有较多的高次谐波，因此，需要利用感性组件105阻高频通低频，将交流信号中含有的高次谐波过滤掉，仅含有基波(正弦波)，比如，具有正弦波形的电压以及具有正弦波形的电流。
在本实施例中，当第一支路与第二支路并联之后的等效阻抗呈阻性时， 也即第三支路上的电压信号与电流信号同相位时，判定待检测负载103为输电负载；当第一支路与第二支路并联之后的等效阻抗不呈阻性时，也就是，第三支路上的电压信号与电流信号不同相位时，判定待检测负载103为加热负载。
基于此，所述检测组件104，配置为检测所述第三交流信号的电压过零点的第一时刻与电流过零点的第二时刻，基于所述第一时刻和所述第二时刻确定所述待检测负载的类型。
在一些实施方式中，所述检测组件104，配置为检测所述第一时刻和所述第二时刻之差是否在第二预设范围内；在检测到所述第一时刻和所述第二时刻之差在所述第二预设范围内的情况下，确定所述待检测负载103的类型为输电负载；在检测到所述第一时刻和所述第二时刻之差不在所述第二预设范围内的情况下，确定所述待检测负载103的类型为加热负载。
其中，第二预设范围可根据需要进行设定，本实施例中对此可不做限定。
例如，第二预设范围为(-0.2，+0.2)，表示大于-0.2小于0.2的范围。在检测到第三支路上的第三交流信号的电压过零点的第一时刻与第三交流信号的电流过零点的第二时刻在(-0.2，+0.2)的情况下，例如第一时刻与第二时刻的差为0.01，则待检测负载103就可判定为输电负载；在检测到第三支路上的第三交流信号的电压过零点的第一时刻与第三交流信号的电流过零点的第二时刻不在(-0.2，+0.2)的情况下，例如第一时刻与第二时刻的差为0.5，则待检测负载103就可判定为加热负载。
采用本申请实施例的技术方案，一方面，通过检测第一支路和第二支路的交流信号的方向，基于检测到的方向实现了自动判定待检测负载的类型。
如图3所示，本申请实施例还提供一种包含上述任一检测电路10的电 器20，所述电器20还包括控制组件30，配置为基于所述检测电路10中的检测组件104确定的所述待检测负载103的类型，控制所述电器进入相应的工作模式。
本实施例中，电器20的工作模式至少包括输电工作模式和加热工作模式。实际应用中，电器20中可至少包括输电电路和加热电路，输电工作模式可表示电器20中的线盘切换连接至输电电路、以通过输电电路对待检测负载103传输电能；加热工作模式可表示电器20中的线盘切换连接至加热电路、以通过加热电路对待检测负载103进行加热。可以理解，在检测电路10检测到待检测负载103类型为加热负载的情况下，控制组件30控制电器20进入加热工作模式；在检测电路10检测到待检测负载103类型为输电负载的情况下，控制组件30控制电器20进入输电工作模式。从而避免人工选择工作模式发生错误，导致电器20或待检测负载103发生损坏。
在实际应用中，在所述待检测负载103包括锅具或受电设备的情况下，所述控制组件30，配置为在所述检测组件104确定的所述待检测负载103的类型为加热负载的情况下，通过所述电器20的线圈盘对放置在所述线圈盘上的锅具进行加热；在所述检测组件104确定的所述待检测负载103的类型为输电负载的情况下，通过所述电器20的线圈盘对放置在所述线圈盘上的受电设备进行输电。
应该理解，所述电器20可为具备上述检测电路10和控制组件30的任何电器，根据本申请的一个具体实施例，所述电器20可为电磁炉，所述待检测负载103可包括能够电磁加热的锅具或能够进行无线充电的搅拌杯。例如，在锅具放置在电磁炉的线圈盘上的情况下，电磁炉通过自身包含的检测电路10与控制组件30，对锅具的类型进行自动识别并控制进入加热工作模式，以对锅具进行加热。又例如，在搅拌杯放置在电磁炉上的情况下，电磁炉通过自身包含的检测电路10与控制组件30，对搅拌杯的类型进行自 动识别控制进入输电工作模式，以对搅拌杯的电池进行充电。
采用本申请实施例的技术方案，将上述检测电路应用于电器中，实现了待检测负载的类型的智能识别，从而可使电器自动的工作在相应的工作模式，使得电器更加智能化，满足用户需求，提高电器的安全性和提升用户的体验。

在此电路拓扑结构下，判断待检测负载的类型可采用以下两种方式：
第一种方式：利用第一支路上的第一交流信号与第二支路上的第二交 流信号进行判断。获取第一交流信号与第二交流信号之间关系，基于二者之间的关系判断待检测负载的类型。
可选的，检测第一支路上的第一交流信号的第一方向及第二支路上的第二交流信号的第二方向，判断第一方向与第二方向之间的夹角是否在第一预设范围内(例如第一方向与第二方向之间的夹角是否接近90°)；若第一方向与第二方向之间的夹角在第一预设范围内，则判定待检测负载为输电负载；若第一方向与第二方向之间的夹角不在第一预设范围内，则判定待检测负载为加热负载。
第二种方式：利用第三支路上的第三交流信号的电压过零点的时刻与第三交流信号的电流过零点的时刻进行判断。
可选的，检测第三支路上的第三交流信号的电压过零点第一时刻与第三交流信号的电流过零点第二时刻；判断第一时刻与第二时刻之差是否在第二预设范围内；若第一时刻与第二时刻之差在第二预设范围内，则判定待检测负载为输电负载；若第一时刻与第二时刻之差不在第二预设范围内，则判定待检测负载为加热负载。
应该理解，上述两种判断方式可同时存在，也可选择其一，根据用户的初始设定确定。当两种判断方式均存在时，可相互作为一种校验，若二者判断的结果不一致时，则判定检测电路有故障或者检测工具有问题，进而使包含此种检测电路的电器停止工作，从而进一步的提高包含此种检测电路的电器的安全性。
需要说明的是，本申请采用上述两种判断方式作为实施例以说明申请构思，应该理解，对于上述电路拓扑结构，还可判断第一支路的第一交流信号的电流值与第二支路的第二交流信号的电流值的平方之和，与第三支路的第三交流信号的电流值的平方之差是否在第三预设范围内；也即计算第一支路的第一交流信号的电流值与第二支路的第二交流信号的电流值的 平方和，与第三支路的第三交流信号的电流值的平方的差值，判断此差值是否在第三预设范围内，在此差值在第三预设范围内的情况下，则确定所述待检测负载的类型为输电负载；在此差值不在第三预设范围内的情况下，确定所述待检测负载的类型为加热负载。其中，所述第三预设范围也可根据实际需要进行设定，本实施例中对此不做具体限定。
例如，第三预设范围设定为(-0.5，0.5)，则在第一支路的第一交流信号的电流值与第二支路的第二交流信号的电流值的平方和，与第三支路的第三交流信号的电流值的平方之间的差值在(-0.5，0.5)的情况下，例如该差值为0.3，则确定待检测负载为输电负载；在第一支路的第一交流信号的电流值与第二支路的第二交流信号的电流值的平方和，与第三支路的第三交流信号的电流值的平方之间的差值不在(-0.5，0.5)的情况下，例如该差值为0.7，则确定待检测负载为加热负载。
综上所述，根据本申请实施例提供的检测电路、电器及控制方法，通过检测电路判断待检测负载的类型，以使电器依据不同的负载类型自动的进入相应的工作模式，能够避免因用户开启错误的按键导致电器不能正常工作，甚至损坏的风险。
