背景技术
微波是一种电磁波，微波炉是一种用微波加热食品的现代化微波烹饪设备。微波炉由电源、磁控管、控制电路和腔体等部分组成。电源向磁控管提供大约4000伏高压，磁控管在电源激励下，连续产生微波，将该微波耦合到腔体内，以加热腔体内的食物。
由此可知，现有微波炉是采用磁控管发射微波，进行微波加热的，且只能进行加热，从而可能导致微波烹饪速度缓慢，影响用户的烹饪体验。再者，如何精确地控制磁控管发出期望功率的微波对于微波炉加热食品而言是非常重要的，然而现有微波炉上并没有任何装置对磁控管发射的微波进行精确的检测，因此很难针对不同食物实施精准有效的加热控制。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。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。
下面参考附图描述本发明实施例的微波烹饪设备及其控制装置。
图1是本申请实施例的微波烹饪设备的控制装置的结构框图。
如图1所示，该微波烹饪设备包括腔体200，腔体200内设置有微波加热件201，控制 装置100包括：功率分配器101、控制电路102、微波源103和电源104。
其中，如图1(a)所示，功率分配器101的输入端口Pin与微波源103连接且输出端口Pout与微波加热件201连接，或者，如图1(b)所示，功率分配器101的输入端口Pin与微波加热件201连接且输出端口Pout与微波源103连接，功率分配器101用于对微波源103输出的微波进行功率分配或者功率合成；控制电路102用于根据给定功率控制微波源103输出微波，并通过功率分配器101将微波源103输出的微波传输至微波加热件201，以对腔体200内的食物进行加热；电源用104于给控制电路102和微波源103供电。
具体地，参照图1(a)，在功率分配器101的输入端口Pin与微波源103连接且输出端口Pout与微波加热件201连接时，在实际应用中，在微波烹饪设备启动后，电源104给控制电路102和微波源103供电，进而控制电路102根据给定功率控制微波源103输出微波，该微波的功率可以是百瓦级到千瓦级功率，功率分配器101对微波源103输出的微波进行功率分配后，传输至微波加热件201，以将微波馈入微波烹饪设备的腔体200中，用来烹饪腔体200中的食物。
其中，微波加热件201可采用天线、波导或者电缆。具体而言，功率分配器101可以输出多路微波，多路微波可通过不同的天线、波导或电缆馈入腔体200。
参照图1(b)，在功率分配器101的输入端口Pin与微波加热件201连接且输出端口Pout与微波源103连接时，即微波源103输出的微波经功率分配器101的输出端口Pout传输至功率分配器101，以及从其输入端口Pin输出，以传输至微波加热件201。在实际应用中，控制电路102根据给定功率控制微波源103输出微波，并传输至功率分配器101，功率分配器101对微波源103输出的微波进行功率合成或传输至微波加热件201，以将微波馈入微波烹饪设备的腔体200中，用来烹饪腔体200中的食物，从而提高微波烹饪设备的总功率能力，加快烹饪速度。
该实施例中，在腔体200的进口处附近，有一个可旋转的搅拌器，该搅拌器是风扇状的金属，旋转起来后对微波具有各个方向的反射作用，进而能够把微波能量均匀地分布在腔体200内，从而加热食物。
应当理解，该实施例中的控制电路102既能够控制微波源103，又可以控制微波烹饪设备，该实施例中的微波烹饪设备可以是微波炉，微波炉的功率范围一般为500瓦～1000瓦。
由此，本申请实施例的微波烹饪设备的控制装置，通过功率分配器既可以实现功率分配，又可以实现功率合成，以对食物进行加热，从而能够加快烹饪速度，提升用户的烹饪体验。
需要说明的是，下面通过各个实施例和示例描述功率分配器101进行功率分配时的具体实施方式，功率分配器101进行功率合成时的具体实施方式可参见功率分配时的具体实 施方式。
在本申请的一个实施例中，如图2所示，功率分配器101可具有M个输出端口Pout1、Pout2、……、PoutM，微波加热件201的个数为M-1个，M为大于1的整数，控制装置100还可包括检波电路105。检波电路105的输入端与M个输出端口Pout1、Pout2、……、PoutM中的一个(例如Pout1)连接，检波电路105的输出端口与控制电路102连接，其中，M个输出端口中的剩余M-1个(例如Pout2至PoutM)与M-1个微波加热件201一一对应连接；其中，控制电路102还用于根据检波电路105检测到的功率信号计算微波源103的输出功率，并根据微波源103的输出功率调整给定功率。
具体地，参照图2，在功率分配器101的输入端口Pin与微波源103连接，其输出端口Pout2至PoutM与微波加热件201连接，输出端口Pout1与检波电路105连接时，控制电路102根据给定功率控制微波源103输出百瓦级到千瓦级功率的微波，该微波经过功率分配器101进行分配，进而通过输出端口Pout1分配一路小功率到检波电路105，检波电路105将该小功率信号转换为电压信号或者数字信号，并发送至控制电路102，以使控制电路102根据该电压信号或者数字信号和功率分配器101的分配比计算出微波源103的总输出功率，从而实现对微波烹饪设备的输出功率的定量检测，而控制电路102亦可转而根据该输出功率来精确地控制微波烹饪设备的输出功率。
功率分配器101的输出端口Pout2至PoutM通过M-1个微波加热件201(例如天线、波导或者电缆)将微波馈入腔体200，用来烹饪腔体200中的食物。需要说明的是，功率分配器101的连接微波加热件201的M-1个输出端口可以设置为比例型、等分型或不等分型，其可以有集总参数、微带线、同轴、波导等多种形式，通过对M-1个微波加热件201的优化组合，可以实现对腔体200内指定区域的加热，以及结合控制电路102的相应控制，也可以实现加热均匀性的提升。
可以理解的是，当功率分配器101的一路输出连接至检波电路105，以进行功率检测时，其效果等同于定向耦合器进行耦合的效果，因此，定向耦合器可以看作一种不等分或比例型的功率分配器。
由此，通过检波电路对微波烹饪设备的输出功率进行精确地检测，有助于根据腔体中的不同食物实施精准有效的控制，从而满足高效、特定的加热需求。
在本申请的一个实施例中，微波源103可采用固态微波源、磁控管或信号发生器，其中，如图3和图4所示，微波源103采用信号发生器时，控制装置100还可包括放大电路106，放大电路106连接在微波源103(信号发生器)与功率分配器101之间，或者，连接在功率分配器101与微波加热件201之间，放大电路106用于对输入至放大电路106的功率进行放大处理，其中，电源104还用于给放大电路106供电(图中未示出)。其中，图 3是在图1的基础上结合该实施例得到的控制装置100的结构框图。
需要说明的是，该实施例中，当微波源103采用固态微波源或者磁控管时，微波源103与功率分配器101是两个独立的器件，微波源103输出微波至功率分配器的输入端口Pin，然后进功率分配器101分配后通过多个输出端口输出至多个微波加热件201，通过对多个微波加热件的优化组合，可以达到多样化的烹饪效果。
进一步地，参照图4，在放大电路106连接在功率分配器101和微波加热件201之间，且放大电路106为多个时，控制电路102还与各放大电路106连接(图中未示出)，用于控制各放大电路106的工作状态，以实现对腔体200内指定区域进行加热或者实现加热的均匀性。其中，图4是在图2的基础上结合该示例得到的控制装置100的结构框图。
具体地，在实际应用中，在微波烹饪设备启动后，电源104给控制电路102、信号发生器103和放大电路106供电，进而控制电路102根据给定功率控制信号发生器103输出小功率信号，并传输至功率分配器101，功率分配器101将该信号分配M路输出，即通过M个输出端口Pout1至PoutM输出，其中一路通过输出端口Pout1输出至检波电路105，以使检波电路105检测到功率型号，进而控制电路102根据该功率信号计算出微波源103的输出功率，从而实现对微波烹饪设备的输出功率的定量检测；剩余M-1路信号分别接入相应的放大电路106，以使放大电路106将该信号的功率放大至百瓦级到千瓦级之间，多个放大电路106的每一路输出分别接入相应的微波加热件201(可采用天线、波导或电缆)，以使放大后的微波通过天线、波导或电缆馈入至微波烹饪设备的腔体200中，用来烹饪腔体200中的食物，其中，控制电路102控制各放大电路106的工作状态，以实现对腔体200内指定区域进行加热或者实现加热的均匀性。
该示例中，当放大电路106为多个，且微波加热件201为多个时，其布局可以根据微波烹饪设备的位置进行设置，以增加设置的灵活性和可执行性。
可以理解的是，图4中的各个放大电路106的每一路输出均可以采用小功率输出，每一路的结构尺寸可以相应的减小，进而可降低放大电路106的成本，因而根据控制电路6对每个放大电路的控制，对每一路输出信号进行控制，可达到优异的烹饪效果。
在本申请的一个实施例中，参照图1(a)、图3，功率分配器101的输入端口Pin与微波源103连接且输出端口Pout与微波加热件201连接时，微波源103的个数为一个且微波加热件201的个数为一个，或者，参照图2、图4，微波源103的个数为一个且微波加热件201的个数为多个；参照图1(b)，功率分配器101的输入端口与微波加热件201连接且输出端口与微波源103连接时，微波源103的个数为多个且微波加热件201的个数为一个。
具体地，在实际烹饪中，在微波源103的个数为一个(即单源)且微波加热件201(例如天线)的个数为一个时，即形成一源一天线的形式，此时功率分配器101进行功率分配； 在微波源103的个数为一个且微波加热件201(例如天线)的个数为多个时，即形成一源多天线的形式，可以理解的是，其中，当微波源103的个数为多个时，即形成多源多天线的形式，此时功率分配器101也进行功率分配。在微波源103的个数为多个(即多源)且微波加热件201(例如天线)的个数为一个时，形成多源一天线的形式，多路微波经功率分配器101合成为一路高功率，从而实现了功率合成。由此，通过对微波源和微波加热件进行不同数量的组合，可以实现更好的煮食体验。
在本申请的一个实施例中，如图5所示，微波烹饪设备还可包括无线充电组件300、微波成像组件400和照明组件500，其中，功率分配器101具有N个输出端口Pout1、Pout2、……、PoutN，N为大于3的整数，多个输出端口设置为等分型或不等分型，N个输出端口中的三个(任意三个，例如Pout1、Pout2、PoutN)与无线充电组件300、微波成像组件400和照明组件500一一对应连接，以分别实现无线充电功能、对腔体200内的食物进行成像和实现照明；其中，控制电路102还与微波成像组件400连接，用于根据食物的成像情况对微波源103的输出功率进行调节。
具体地，参照图5，实际应用中，在功率分配器101的输出端口Pout1连接充电组件300时，即可通过该输出端口输出的微波对微波烹饪设备内的其余部件、附件或其他设备进行无线充电，以保证微波烹饪设备的工作时长，防止因电量不足而中断工作；在功率分配器101的输出端口Pout2连接照明组件500时，即可通过该输出端口输出的微波对微波烹饪设备内的其余部件、附件或其他设备进行照明，使用户更加清楚地查看微波烹饪设备；在功率分配器101的输出端口PoutN连接微波成像组件400时，即可通过该输出端口输出的微波对微波烹饪设备的对腔体200内的食物进行成像，并将食物成像结果传输至控制电路102，以使控制电路102根据食物的成像情况对微波源103的输出功率进行调节，进而根据该输出功率调整给定功率，以保证更好的煮食效果。
由此，功率分配器的多个输出端通过连接不同的功能组件，实现不同的功能，有助于微波烹饪设备的功能性扩展，使微波烹饪设备具有更多功能。
可以理解的是，该实施例中的功率分配器101的N个输出端口Pout1、Pout2、……、PoutN可以为比例型，也可以为等分型或不等分型，其可以设置为集总参数、微带线、同轴、波导等多种形式，具体选用的形式根据其具体情况而定，此处不做限制。
在本申请的一个示例中，参照图3，控制电路102、信号发生器103、功率分配器101和放大电路106集成设置(如图3中的虚线框所示)。
具体地，在图1的基础上，在功率分配器101和微波加热件201之间接入放大电路106时，控制电路102、信号发生器103、功率分配器101和放大电路106集成设置，既可以减小控制装置100的空间尺寸，又易于降低成本。
在本申请的另一个示例中，参照图4，控制装置100包括检波电路105时，检波电路105、控制电路102、信号发生器103、功率分配器101和放大电路106集成设置(如图4中的虚线框所示)。
具体地，参照图2，在控制装置100包括检波电路105时，功率分配器101的一个输出端(例如Pout1)连接至检波电路105，剩余的M-1个输出端连接至微波加热组件201，因此，参照图4，功率分配器101和微波加热件201之间连接放大电路106时，放大电路106的个数可以是微波加热件201的个数。检波电路105、控制电路102、信号发生器103、功率分配器101和放大电路106集成设置，既可以减小控制装置100的空间尺寸，又易于降低成本。
可以理解的是，控制电路102既可以控制微波烹饪设备的控制装置100，又可以控制微波烹饪设备，还可以和微波烹饪设备的其他控制板及你在哪个连接，共同实现良好的控制，以达到更好的煮食效果。
综上所述，本申请实施例的微波烹饪设备的控制装置，通过功率分配器既可以实现功率分配，又可以实现功率合成，以对食物进行加热，从而能够加快烹饪速度，提升用户的烹饪体验；通过检波电路对微波烹饪设备的输出功率进行精确地检测，有助于根据腔体中的不同食物实施精准有效的控制，从而满足高效、特定的加热需求，能够针对不同食物实施精准有效的加热控制；通过对微波源和微波加热件进行不同数量的组合，可以提升用户煮食体验。
