本发明的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本发明中的具体含义。
参照图1、图2和图3，为本发明一种实施例的烤箱1000，可以用来烘烤食物。为了缩短食物的制作时间，烤箱1000通过分步升温的加热控制方法，来加快食物的烤熟。
继续参照图1、图2和图3，本发明的实施例中，烤箱1000包括箱体100、箱门120、加热装置200、烤盘300和风机400。箱体100内设置有烘烤腔110，烘烤腔110用于容纳食物。烤盘300安装在烘烤腔110内，烤盘300用于承托食物。箱门120转动连接于箱体100，以打开或封闭烘烤腔110。加热装置200设置在烘烤腔110内，用于对烘烤腔110进行加热。其中，烘烤腔110沿竖直方向的尺寸小于烘烤腔110沿水平方向任意一边的尺寸，也就是烘烤腔110呈扁平状。而加热装置200沿水平方向布置，因此食物在烘烤过程中能更靠近加热装置200，从而加快食物烤熟。风机400安装于箱体100的内侧壁，风机400用于加快烘烤腔110内的热风循环，以使烤箱1000内的温度分布更均匀。
参照图5，基于上述实施例的烤箱1000的加热控制方法，包括下列步骤：
步骤S501：获取预热指令。预热指令可以是用户根据烤箱1000上的控制面板，选择相应的预热按钮按下后产生，也可以是通过手机APP在线控制烤箱1000，并选择预热功能后产生，或者是烤箱1000设定了定时启动预热功能，达到设定时间后产生预热指令。具体根据实际情况选择合适的方案，本发明在此不再具体限定。
步骤S502：根据预热指令，控制加热装置200以第一功率加热烘烤腔110。可以理解的是，预热的目的是提高食物加热的效率，有效避免食物在长时间的加热过程中水分损失过大而变干发脆。烘烤腔110预热后再放入食物，高温下食物表面瞬间炙烤成焦黄，并且能够保 留食物内部的水分，提升食物的口感。
预热过程中采用第一功率加热，本实施例中第一功率的设置与烤箱1000的预热温度相适配。本发明的实施例中，预热温度为200℃至400℃，例如250℃，该温度高于相关技术的烤箱1000的最高温度230℃，从而能够为下一步快速烘烤提供有利的条件。需要说明的是，第一功率为加热装置200的总功率，加热装置200包括上加热管210和下加热管220，即第一功率为上加热管210和下加热管220的功率之和。可以理解的是，上加热管210和下加热管220可采用相同的功率进行预热，以保证预热后的烘烤腔110的温度更为均匀。需要说明的是，预热阶段风机400可以工作，进一步提高预热的效率。此外，相关技术的烤箱1000通常没有独立的预热旋钮，用户一般通过加热旋钮旋转选择相应的温度进行预热，而本发明实施例的烤箱1000设有独立的预热按钮，预热温度的大小可以是程序预先设定的，只需要用户按下预热按钮即可将烘烤腔110预热至设定的温度。本发明的另一种实施例中，预热温度的大小也可以是由用户自定义的，选择相应的温度后，烘烤腔110被加热至用户自定义的温度。
步骤S503：获取烘烤腔110的温度。可以通过温度传感器检测烘烤腔110的温度，温度传感器检测烘烤腔110中心处的温度，并将检测到的参数反馈至处理器。也可以是通过多个温度传感器，检测烘烤腔110内多个不同位置的温度，并将检测到的多个位置的温度反馈至处理器，取平均值进行计算。具体根据实际情况选择合适的方案，本发明在此不再具体限定。
步骤S504：当烘烤腔110的温度大于或等于预热温度，控制加热装置200以预热温度进行保温运行。可以理解的是，预热完成后，用户可能不能第一时间将食物放进烘烤腔110，因此需要加热装置200保温运行。保温运行的控制逻辑可以是：当烘烤腔110的温度大于或等于预热温度，加热装置200停止工作，经过一定时间后，温度传感器检测到烘烤腔110中心处的温度低于预热温度，则控制加热装置200重新加热，加热时的功率可以是以第一功率运行，也可以是低于第一功率运行。保温运行的控制逻辑还可以是：当烘烤腔110的温度大于或等于预热温度，加热装置200以一个较小的功率运行，以使烤箱1000的散热量大致等于加热量，从而达到保温的效果。
需要说明的是，当烘烤腔110的温度大于或等于预热温度，还可以发出烘烤提示，例如蜂鸣、灯闪等等。烤箱1000可以安装蜂鸣器，当预热完成，也就是烘烤腔110的温度大于或等于预热温度，控制蜂鸣器发出蜂鸣，以提醒用户。烤箱1000也可以安装信号灯，当预热完成时信号灯亮，或者是其他采用信号灯提示的方式，在此不再具体限定。或者，同时安装蜂鸣器和信号灯。在本发明的另一种实施例中，也可以是将预热完成的信息发送至用户的手机APP，提示用户预热完成，可以放入食物进行烘烤。
步骤S505：获取烘烤指令。烘烤指令可以是用户根据烤箱1000上的控制面板，选择相 应的烘烤按钮按下后产生，也可以是通过手机APP在线控制烤箱1000，并选择烘烤功能后产生。具体根据实际情况选择合适的方案，本发明在此不再具体限定。
步骤S506：根据烘烤指令，控制加热装置200进入快速加热模式，其中，控制加热装置200进入快速加热模式包括控制加热装置200以第二功率加热烘烤腔110。例如，快速加热模式中，加热装置200持续以第二功率对烘烤腔110进行加热，将烘烤腔110内加热至更高的温度，高温能加快食物烤熟。本发明的另一种实施例中，加热装置200以第二功率断续对烘烤腔110进行加热，例如，加热装置200每加热1分钟，则停止加热10秒，后续再加热1分钟，周期循环，断续加热。或者，断续加热也可以是非周期加热，例如，加热装置200先持续加热5分钟，后停止加热10秒，后再加热2分钟。具体根据实际情况选择合适的加热逻辑，本发明在此不再具体限定。
可以理解的是，步骤S206中，控制加热装置200进入快速加热模式之后，还可以包括：
控制风机400工作以加快所述烘烤腔110的气流循环。风机400用于加快烘烤腔110内的热风循环，以使烤箱1000内的温度分布更均匀。需要说明的是，风机400是否开启根据烘烤的食物决定，当需要食物口感较干时，开启风机400，例如烤牛排、饼干；当需要食物保留水分时，关闭风机400，例如烤披萨、蛋糕。
步骤S507：当烘烤腔110的温度大于或等于烘烤温度，控制加热装置200以烘烤温度进行保温运行，其中，烘烤温度大于预热温度。可以理解的，温度太高容易造成食物表面碳化，水分流失，因此在烘烤腔110的温度升高至烘烤温度后需要以烘烤温度保温运行。本发明的实施例中，烘烤温度为300℃至450℃。需要说明的是，烘烤温度需要满足大于预热温度的条件，例如预热温度为250℃，则烘烤温度可以为300℃；预热温度为400℃，则烘烤温度可以为410℃。
需要说明的是，烘烤指令还包括预设烘烤温度数值的参数信息，例如烘烤温度为350-410℃。需要说明的是，烘烤温度的大小可以是程序预先设定的，只需要用户按下烘烤按钮即可将烘烤腔110升温至设定的温度。例如对于蔬菜、糕点、少量的肉类等烘烤温度设定在较低的范围；对于一些大块的肉类，例如牛排、羊排、烤鸡等，烘烤温度则设定在较高的范围。烘烤温度的大小也可以是由用户自定义的，选择相应的温度后，烘烤腔110被加热至用户自定义的温度。
可以理解的是，参照图6，步骤S506之后，还可以包括步骤S509：当烘烤腔110的温度大于或等于烘烤温度，控制加热装置200以烘烤温度进行保温运行，其中，烘烤温度等于预热温度。例如预热阶段直接将烤箱1000的温度升温至350-410℃，后续将食物放进烘烤腔110后，继续以此温度进行烘烤。因此减少了从预热温度升温至烘烤温度这一阶段所需的时间， 能进一步缩短食物制作的时长。
步骤S508：在加热装置200进入快速加热模式达到第一预设时长后，控制加热装置200停止加热。本发明的实施例中，第一预设时长为0.5分钟至8分钟，而市面上的烤箱的第一预设时长，或者说烘烤时长通常在20分钟以上。可以理解的是，本发明实施例的烤箱1000的烘烤温度通常高于市面上的烤箱1000，虽然高温能使食物表面变得焦脆，其内部仍旧保持一定的水分，但是烘烤时间不宜过长，以免食物表面焦黑，烘干后口感不佳。因此在进入快速加热模式达到第一预设时长后，需要停止加热，以免食物烤焦，且防止箱体100外表面温度过高，提高烤箱1000的安全性。
可以理解的是，参照图7，步骤S507之后，还可以包括步骤S510：在加热装置200进入快速加热模式达到第一预设时长后，以预设温度进行保温运行，其中，预设温度小于预热温度。例如预热温度为250℃，而预设温度为65℃。当食物没有第一时间取出时，预设温度为65℃可以起到保温作用，避免食物在长时间的放置下变凉，影响口感。
可以理解的是，烤箱1000的加热控制方法主要包括两个阶段：预热阶段和继续升温阶段。预热阶段的主要作用是：预热后再放入食物，食物能瞬间在高温下炙烤，表面焦黄，保留食物内部的水分，提升口感。继续升温阶段的主要作用是：加快食物烤熟，使食物表面焦脆，缩短用户的等待时间。
本发明的实施例中，第二功率大于第一功率。例如，当烤箱1000的整机功率为2000W，预热时，加热装置200的第一功率为1600W，而烘烤时，加热装置200的第二功率可以是1800W。由于预热阶段加热装置200自身的温度已经足够高，因此后期以更高功率进行加热时，烘烤腔110内的温度上升较快。例如，预热阶段加热到250℃所需时间为10-15分钟，后期升温至400℃时，仅需要4-5分钟。因此第二功率大于第一功率能加快烘烤腔110的升温速率，加快食物烤熟。
参照图2、图3和图4，本发明的实施例中，烤箱1000还包括烤盘300和风机400，烤盘300安装在烘烤腔110内，烤盘300用于承托食物。风机400安装于箱体100的内侧壁，风机400用于加快烘烤腔110内的热风循环，以使烤箱1000内的温度分布更均匀。加热装置200包括上加热管210和下加热管220，上加热管210和下加热管220分别位于烤盘300的上方和下方，上加热管210主要对食物上方进行加热，下加热管220主要对食物下方进行加热。
参照图8，基于上述实施例的烤箱1000的加热控制方法，根据烘烤指令，控制加热装置200进入快速加热模式，具体包括下列步骤：
步骤S801：若烘烤指令为第一模式指令，控制上加热管210以第三功率加热，并控制下加热管220以第四功率加热。例如，上加热管210持续以第三功率加热，下加热管220持续 以第四功率加热。第三功率和第四功率之和为第二功率。
第一模式指令一般用于烘烤糕点一类的食物，例如蛋糕、披萨等。以烘烤披萨为例，烤披萨的预热温度可以是250℃，当达到预热温度，获取第一模式指令，也就是用户按下第一模式的功能按钮。其中，第一模式指令中包括了烘烤披萨所需的各种预置参数，例如烘烤温度，烘烤时间，上加热管210和下加热管220的控制逻辑以及上加热管210和下加热管220的加热功率大小等等。因此能一键烤制披萨，减少用户的操作步骤，提高用户的使用体验。
当获取第一模式指令，控制上加热管210持续以第三功率加热，并控制下加热管220持续以第四功率加热，此时风机400不工作。可以理解的是，烤披萨需要软熟，能够拉丝，以保持披萨的口感。如果烤披萨时启动风机400，容易导致披萨表面的水分流失加快，因此开风机400烤制的披萨较干，口感不好。本发明的另一种实施例中，上加热管210可以断续以第三功率加热，下加热管220断续以第四功率加热。具体参照前文实施例，本实施例在此不再赘述。
本发明的一种实施例中，烤披萨的烘烤温度为350-370℃，而烘烤的时间，也就是第一预设时长在3-8分钟。可以理解的是，采用本发明实施例的加热控制方法，披萨可以在3-8分钟内烤熟。通常来说，蔬菜类的披萨所需时间较短，肉类披萨所需时间较长。而市面上的普通烤箱，烤制披萨的温度维持在200℃左右，所需时长普遍为15-25分钟。例如，烤制具有相同食材、大小的披萨，采用本申请的加热控制方法，仅需要8分钟，而采用现有技术的加热方法，需要25分钟。因此，采用本发明实施例的加热控制方法，能加快披萨烤熟，缩短用户的等待时间。虽然高温会加快水分的流失，但是由于烤披萨只需要3-8分钟，时间不长，水分流失少，烤制出来的披萨不会太干。因此用户在缩短等待时间的前提下，同时保证披萨的口感，提高了用户的使用体验。
参照图2、图3和图4，本发明的实施例中，烤箱1000还包括烤盘300和风机400，烤盘300安装在烘烤腔110内，烤盘300用于承托食物。风机400安装于箱体100的内侧壁，风机400用于加快烘烤腔110内的热风循环，以使烤箱1000内的温度分布更均匀。加热装置200包括上加热管210和下加热管220，上加热管210和下加热管220分别位于烤盘300的上方和下方，上加热管210主要持续对食物上方进行加热，下加热管220主要持续对食物下方进行加热。由于烘烤腔110呈扁平状，因此将风机400设置在箱体100的内侧壁，以使烤箱1000的整体结构统一。
参照图9，基于上述实施例的烤箱1000的加热控制方法，根据烘烤指令，控制加热装置200进入快速加热模式，具体包括下列步骤：
步骤S901：若烘烤指令为第二模式指令，控制上加热管210以第二功率加热，并控制风 机400工作以加快烘烤腔110的气流循环。
第二模式指令一般用于肉类食物，例如牛排、羊排等。以烘烤牛排为例，烤牛排的预热温度可以是250℃，当达到预热温度，获取第二模式指令，也就是用户按下第二模式的功能按钮。其中，第二模式指令中包括了烘烤牛排所需的各种预置参数，例如烘烤温度，烘烤时间，上加热管210和下加热管220的控制逻辑以及风机400是否工作等等。因此能一键烤制牛排，减少用户的操作步骤，提高用户的使用体验。
当获取第一模式指令，控制上加热管210加热烘烤腔110，下加热管220不加热，且控制风机400工作。风机400设置在烘烤腔110的左侧或者后侧，也就是烘烤腔110长度方向的一侧，因此便于将上加热管210和下加热管220产生的热量从靠近风机400的一端吹向远离风机400的一端，以加快烘烤腔110的热风循环，使热风遍布烘烤腔110的绝大部分位置，进而使烘烤腔110内部的温度分布更均匀，加快肉类食物的烘烤速度，提升烹饪的质量。
可以理解的是，烤牛排时要求牛排上表面焦脆，下表面刚熟，因此下加热管220不加热，但是牛排的下表面不能夹生。而开风机400可以较好的解决这个问题，风机400能将烘烤腔110内的温度分布变得更均匀，弥补牛排下表面温度不足的情况；且开风机400可以加快食物水分的流失，因此容易使牛排的表面焦脆，而牛排会在烤熟后再加入调味汁进行入味。需要说明的是，本发明的另一种实施例中，由于不需要下加热管220加热，因此烤箱100可以没有下加热管220。
本发明的实施例中，烤牛排的烘烤温度为400-410℃，而烘烤的时间，也就是第一预设时长在2-6分钟。可以理解的是，采用本发明实施例的加热控制方法，牛排可以在2-6分钟内烤熟，根据用户需要的不同熟度，烤制的时间不同，当然，也和牛排的厚薄有关。而市面上的普通烤箱，烤制牛排的温度维持在210℃左右，所需时长普遍为17-25分钟。例如，在牛排具有相同厚度、大小的情况下，采用本发明实施例的加热控制方法，烤制一块牛排的时间为6分钟，而采用现有技术的方法，所需时间为25分钟。因此，采用本发明实施例的加热控制方法，能加快牛排烤熟，缩短用户的等待时间。
当烤箱1000预热完成，若用户没有进一步操作，一直保持保温状态是高耗电的行为，且容易降低烤箱1000的使用寿命，因此烤箱1000在保温一段时间后，用户没有烤制食物，则需要控制加热装置200停止加热。因此，参照图10，本发明的实施例中，控制加热装置200以预热温度进行保温运行之后，还包括：
步骤S1001：在加热装置200以预热温度进行保温运行达到第二预设时长，控制加热装置200停止加热。
本发明的实施例中，第二预设时长为5-20分钟。需要说明的是，第二预设时长可以是烤 箱1000在出厂后就已经确定的参数，也可以是由用户自行设定的参数。具体根据实际情况选择合适的方案，本发明在此不再具体限定。
本发明的一个实施例还提供了一种烤箱1000，该烤箱1000包括：存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序。处理器和存储器可以通过总线或者其他方式连接。
存储器作为一种非暂态计算机可读存储介质，可用于存储非暂态软件程序以及非暂态性计算机可执行程序。此外，存储器可以包括高速随机存取存储器，还可以包括非暂态存储器，例如至少一个磁盘存储器件、闪存器件、或其他非暂态固态存储器件。在一些实施方式中，存储器可选包括相对于处理器远程设置的存储器，这些远程存储器可以通过网络连接至该处理器。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
实现上述实施例的烤箱的控制方法所需的非暂态软件程序以及指令存储在存储器中，当被处理器执行时，执行上述实施例中的烤箱的控制方法，例如，执行以上描述的图5中的方法步骤S501至步骤S508、图6中的方法步骤S509、图7中的方法步骤S510、图8中的方法步骤S801、图9中的方法步骤S901、图10中的方法步骤S1001。
以上所描述的装置实施例仅仅是示意性的，其中作为分离部件说明的单元可以是或者也可以不是物理上分开的，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。
上面结合附图对本发明实施例作了详细说明，但是本发明不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
