具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开 实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
下面所描述的本公开不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
现有蒸烤箱多为储水式蒸汽发生器,其控制方式简单,但是蒸汽效率低,所产生的蒸汽为饱和蒸汽，蒸汽湿度比较高，在内胆中冷凝水较多，使用该蒸汽进行烹饪时存在食物口感差、冷凝水清除困难的问题，进而影响用户的使用体验。
针对这一问题，即热式蒸汽发生器应用而生，即热式蒸汽发生器在水补充瞬间产生蒸汽，并且所产生的蒸汽为过热蒸汽，蒸汽湿度低，使用该蒸汽进行烹饪时冷凝水少、食物口感佳、不需要频繁清除冷凝水用户体验较好，于此同时耗水量也较低，因此，即热式蒸汽发生器非常适合应用于利用蒸汽进行烹饪的烹饪设备。
但是，由于即热式蒸汽发生器自身温度容易波动，蒸汽发生器感温包反馈温度存在一定的延时，容易出现补水过多的情况，降低了蒸汽发生器的工作温度，进而导致进水不能及时蒸发，蒸汽发生器出口喷水的问题，影响烹饪效果。因此，如何控制即热式蒸汽发生器持续不间断产生满足烹饪要求的蒸汽，成为一个新的挑战。
基于上述问题，本公开实施例提供了一种蒸汽发生器控制方法，应用于如图1所示的蒸烤箱的控制器，该蒸烤箱包括：蒸汽发生器1、水泵2、内胆3及设置在蒸汽发生器1上的感温包4，其中，蒸汽发生器1的进水管路5与水泵2连接，通过水泵2为蒸汽发生器1进行补水，蒸汽发生器1的出汽口6通 过出汽管路7与蒸烤箱的内胆3连接，被设置为将过热蒸汽输入内胆3中进行食材的烹饪，感温包4被设置为采集蒸汽发生器1的工作温度信号，并将该温度信号发送至蒸烤箱的控制器(图1中未示出)。
如图2所示，本公开实施例提供的蒸汽发生器控制方法，主要包括如下步骤：
步骤S101：获取蒸汽发生器的目标工作温度。
其中，该目标工作温度为设置在烤箱中的蒸汽发生器产生满足蒸烤箱烹饪要求所需过热蒸汽时的最佳温度，具体可根据不同的蒸烤箱产品及用户的烹饪要求等进行灵活的调整，在本公开实施例中，是以该目标工作温度为140℃为例进行的说明，仅以此为例，但并不以此为限。
步骤S102：按照预设时间周期获取蒸汽发生器的当前工作温度。
其中，该当前工作温度可由设置于蒸汽发生器上的感温包发送的温度信号得到，该预设时间周期为蒸烤箱中蒸汽发生器的最小调整单元，具体可根据蒸烤箱中蒸汽发生器的控制精度要求进行设置，控制精度要求越高则对应的预设时间周期越短，反之，控制精度要求越低对应的预设时间周期越长。
步骤S103：根据当前工作温度与目标工作温度的关系确定水泵在下一预设时间周期的工作时长。
其中，该工作时长为下一预设时间周期中水泵为蒸汽发生器进行补水的总时长，从而可以周期性地对蒸汽发生器进行补水控制，避免一次补水过多，同时又保证蒸汽发生器可持续产生满足要求的过热蒸汽。
步骤S104：在下一预设时间周期中，基于工作时长控制水泵为蒸汽发生器进行补水。
其中，在下一预设时间周期内水泵如何工作，可以根据实际需要进行灵活的调整，只有保证水泵在该预设时间周期内的工作总时间达到上述工作时长即可，如：在预设时间周期开始时直接控制水泵工作直至达到工作时长，或者在预设时间周期开始时不启动水泵工作，在预设时间周期剩余时间与工作时长相等时控制水泵开始工作直至该预设时间周期结束等，本公开并不以此为限。
通过执行上述步骤，本公开实施例提供的蒸汽发生器控制方法，通过周期性的检测蒸汽发生器的当前工作温度，并根据其与目标工作温度的关系，调整下一周期水泵的工作时长，并在下一周期按照该工作时长控制水泵为蒸汽发生器进行补水，从而利用这种周期控制的方式调整补水量，为蒸汽发生器提供更加精准的补水，避免一次补水量过多导致进水不能及时蒸发，蒸汽发生器出口喷水的问题，为用户持续提供符合满足使用要求的蒸汽，提高用户的使用体验。
具体地，在一实施例中，上述的步骤S103，具体包括如下步骤：
步骤S201：计算当前工作温度与目标工作温度的温度差值。
步骤S202：基于温度差值及预设PID控制算法，计算工作时长。
具体地，由于蒸汽发生器在上述140℃左右时，能够持续输出满足蒸烤箱需求的过热蒸汽，如果蒸汽发生器缺水，则无法产生足量的过热蒸汽，于此同时，还会导致蒸汽发生器的温度上升，因此，需要通过水泵进行补水，为了提高蒸汽发生器补水的精确性，本公开实施例通过预设的PID算法将温度蒸发器的工作温度作为控制目标，利用温度差值计算出水泵的工作时长，以始终保持蒸发器温度控制在目标工作温度的范围内，从而进一步提高了蒸汽蒸发器补水的精确性。其中，该目标工作温度的范围是指目标工作温度附近的温度区间，蒸汽发生器在该温度区间中工作，可以持续输出满足蒸烤箱要求的过热蒸汽，该温度范围可根据蒸烤箱的实际工作情况进行设置，在本公开实施例中，该目标工作温度的范围为(130℃，150℃)，仅以此为例，并不以此为限。
在另一可替换实施例中，上述的步骤S103，具体包括如下步骤：
步骤S301：计算当前工作温度与目标工作温度的温度差值；
步骤S302：基于温度差值及预设温度与工作时长关系，计算工作时长。
其中，该预设温度与工作时长关系为根据蒸烤箱的历史工作数据通过利用人工智能分析方法所得到的，该预设温度与工作时长关系即为当前工作温度与目标工作温度相比，每增加一℃，则对应的下一预设周期所需的水泵的补水时间，进而可以精准确定下一周期所需的补水量，以避免单次补水过量导致蒸汽发生器出汽口喷水的问题，有利于维持蒸汽发生器工作温度稳定，以持续产生高质量的过量蒸汽，进一步提高用户使用体验。
具体地，在一实施例中，上述的步骤S104，具体包括如下步骤：
步骤S401：基于预设时间周期与工作时长的关系，确定水泵的运行占空比。
步骤S402：在下一预设时间周期中，基于运行占空比控制水泵进行脉冲式补水。
在实际应用中，如果在某一时间内对水泵进行连续补水后，会导致蒸汽发生器的温度快速下降，但是蒸汽发生器上感温包感温延时，不能快速感应到蒸汽发生器的变化，导致水泵补水过多，蒸汽发生器温度较低，热量不足蒸发过多的水，导致蒸汽发生器出汽口出现喷水现象，烹饪效果差。因此，在本公开实施例中，为了进一步提高水泵补水的精确性，避免蒸汽发生器由于补水过多导致温度急剧下降的问题，通过计算水泵的工作时长在预设时间周期的占比，确定水泵的运行占空比，并在下一预设周期控制水泵按照该运行占空比进行脉冲式补水，假设水泵的工作时长为50ms，预设时间周期为250ms，则运行占空比为1：5，则可以控制水泵在下一预设周期中每运行10ms后停止40ms，具体每一个运行周期的时间可以根据实际需要进行设置，本公开实施例仅以50ms 为一个运行周期为例，并不以此为限。需要说明的是，在实际应用中，也可以按照固定运行占空比的方式控制水泵运行，如固定运行占空比为1:2，一个运行周期依然为50ms，则可以控制水泵在下一预设周期中运行25ms，停止25ms，直至总运行时间达到水泵在该预设时间周期的工作时长即可，本公开并不以此为限。
通过上述水泵的脉冲式补水方式，降低水泵瞬间水量补充，使一次性补水不会过多，由原来的一次性补水量分为多个占空比补水，解决一次性补水量过多导致蒸汽发生器快速下降，蒸汽发生器感温包延时的问题。此外，在实际应用中，还可以通过降低水泵转速的方式来降低水泵瞬间水量补充，也可以将降低水泵转速与脉冲式补水进行联合使用，并适应性地进行调整，以达到更为理想的补水效果，在此不再进行赘述。
具体地，在一实施例中，在执行上述的步骤S103之前，上述的蒸汽发生器控制方法还包括如下步骤：
步骤S105：判断蒸汽发生器是否为通电后首次工作。
步骤S106：当蒸汽发生器为通电后首次工作时，判断当前工作温度是否达到第一预设温度。
其中，该第一预设温度小于目标工作温度，具体地，该第一预设温度可以根据蒸汽发生器的实际工作要求进行设置，在本公开实施例中，该第一预设温度为135℃，仅以此为例，并不以此为限。
步骤S107：当当前工作温度达到第一预设温度时，启动水泵开始抽水，直至当前工作温度达到目标工作温度。
具体地，在蒸汽发生器首次通电工作时，为了避免管路中是无水状态，水进入到蒸汽发生器前必须先充满进水管路，因此，水在进入蒸汽发生器会存在 一定的延时，如果进水不及时容易导致蒸汽发生器温度过高而损坏，而如果进水过早，蒸汽发生器尚未达到目标工作温度，容易导致出汽口喷水，或者会降低蒸汽发生器当前工作温度，无法达到目标工作温度，不利于过热蒸汽的产生。因此，本公开实施例在对蒸汽发生器进行控制前，首先判断其是否为通电后首次工作，如果是首次工作，则在其达到135℃时，即达到目标工作温度附近时，控制水泵进水，从而通过精准控制水泵提前进水的时间，既避免了蒸汽发生器温度过高而损坏，又避免了蒸汽发生器工作温度下降造成出汽口喷水的问题，有利于位置蒸发生器工作稳定，向蒸烤箱内胆持续输出高质量的过热蒸汽进行烹饪，保障烹饪食材的口感，提高用户的使用体验。
具体地，在一实施例中，上述的蒸汽发生器控制方法还包括如下步骤：
步骤S108：判断当前工作温度是否大于第二预设温度。
其中，该第二预设温度大于目标工作温度，具体地，该第二预设温度可以根据蒸汽发生器的工作要求进行设置，在本公开实施例中，该第二预设温度为200℃，仅以此为例，并不以此为限。
步骤S109：当当前工作温度大于第二预设温度时，控制蒸汽发生器停止运行。
具体地，为了避免蒸汽发生器异常干烧问题，当监测到蒸汽发生器的当前工作温度大于200℃，自动控制蒸汽发生器停止工作，相应地，可以通过语音或者指示灯的形式向用户提示故障信息，以及时提醒用户对蒸烤箱进行相应的检修，从而延长蒸汽发生器和蒸烤箱的使用寿命。
下面将结合具体应用示例，对本公开实施例提供的蒸汽发生器控制方法进行详细的说明。
图3为蒸汽发生器的一个具体控制过程示意图，在蒸烤箱开始上电工作时， 蒸汽发生器一直保持工作状态，水泵给蒸汽发生器提供水源，水在蒸汽发生器的高温下快速行成蒸汽从蒸汽发生器出口排出进入到烤箱内胆，给蒸汽发生器进行烹饪。当蒸汽发生器感温包温度大于135℃时，判断此时是否为蒸烤箱通电后首次工作，如果当前为首次工作，为了避免管路中是无水状态，水泵提前进入工作状态，避免进水延时。当蒸汽发生器感温包温度大于140℃时，控制器通过PID算法计算需要水泵下一时间周期的工作时间进行补水，始终保持蒸汽发生器工作温度在140℃±10℃范围内，持续输出过热蒸汽。同时为了出现蒸汽发生器异常干烧问题，当蒸汽发生器感温包温度≥200℃时，控制蒸汽发生器停止工作。
从而保障蒸汽发生器可持续稳定工作，输出过热蒸汽，解决蒸汽发生器感温包反馈温度延时导致补水不准确，蒸汽发生器出口喷水的问题，并且保障过热蒸汽湿度低，减少内胆冷凝水，保障烹饪食材的口感，提高用户体验。
