具体实施方式
本申请是基于申请人对以下事实和问题的发现和认识作出的：
相关技术中诸如蒸箱的烹饪器具，其烹饪时蒸汽填充烹饪腔的速度较慢，导致烹饪腔升温较慢，影响烹饪效率和烹饪效果。
具体而言，相关技术中的蒸箱，其蒸汽通过喷口以一定速度喷入烹饪腔，由于蒸汽喷入的速度较快，蒸汽主要集中在喷口的延伸方向的路径上，需要较长的时间才能逐渐填充烹饪腔的其他位置，导致填充速度较慢，烹饪腔升温较慢，影响烹饪效率和烹饪效果。
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，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请一些实施例的进汽结构1。
如图1-图3所示，根据本申请实施例的进汽结构1包括箱体10和分汽板20。箱体10上设有进汽口11。分汽板20将箱体10内的空间分隔为进汽腔12和烹饪腔13，分汽板20上设有多个分汽孔21，所述进汽腔12与进汽口11连通。具体而言，蒸汽通过进汽口11进入后，分散至多个分汽腔120后，再分别通过多个分汽孔21进入烹饪腔13。
根据本申请实施例的进汽结构1，结合图1，通过设置分汽板20，可以利用分汽板20将箱体10内的空间分隔为进气腔12和烹饪腔13，这样蒸汽通过进汽口11进入后，可以先在进汽腔12内分散后，再通过多个分汽孔21进入烹饪腔13，使蒸汽均匀分散地进入烹饪腔13中，避免蒸汽过于集中，使蒸汽形成整体的蒸汽层，随蒸汽的填充将空气挤出而不会与空气掺混，便于蒸汽快速充满烹饪腔13，提高蒸汽的填充效率，从而提高进汽结构1的进汽效率，提高烹饪腔13升温速度。
下面参考附图描述根据本申请具体实施例的进汽结构1。可选地，隔板30将所述进汽腔分隔为多个分汽腔120，每个分汽腔120至少与一个分汽孔21连通，通过在进汽腔12内设置隔板30，可以将进汽腔12进一步分隔出多个分汽腔120，由此可以使蒸汽通过进汽口11进入后，可以先分散至多个分汽腔 120内，再通过分别与多个分汽腔120连通的分汽孔21进入烹饪腔13。进一步避免蒸汽集中，进一步便于蒸汽快速充满烹饪腔13，进一步提高蒸汽的填充效率，从而提高进汽结构1的进汽效率，提高烹饪腔13升温速度。也就是说，进汽结构1通过设置分汽板20和隔板30，可以促使蒸汽均匀分散地填充烹饪腔13，相比相关技术中的技术方案，可以提高烹饪腔13的蒸汽填充效率，提高进汽结构1的进汽效率，提高烹饪腔13的升温速度。
因此，根据本申请实施例的进汽结构1具有进汽效率高、填充速度快等优点。
可选地，如图1-图3所示，根据本申请实施例的进汽结构1包括箱体10、分汽板20和隔板30。具体地，如图1-图3所示，隔板30上设有过汽孔31，隔板30为多个且沿进汽方向间隔设置。这里需要理解的是，“进汽方向”为进汽口11引导后的蒸汽进入方向，例如图中的箭头a所示。这样可以使蒸汽通过进汽口11进入后，先后通过过汽孔31进入多个分汽腔120，从而可以进一步降低蒸汽流速，便于蒸汽分散进入烹饪腔13，便于提高蒸汽填充烹饪腔13的效率。
有利地，每相邻两个隔板30之间的距离沿进汽方向逐渐增大。由于蒸汽先后经过多个隔板30后的流速逐渐降低，通过合理排布隔板30的间距可以逐渐降低隔板30对蒸汽的阻碍和分散效果，从而使蒸汽更加均匀地分散，进一步便于蒸汽分散填充烹饪腔13。
更为具体地，如图1-图3所示，隔板30垂直于进汽方向。这样可以提高隔板30对蒸汽的减速分散效果。
更为有利地，如图1-图3所示，隔板30上设有多个间隔设置的过汽孔31。由此可以使蒸汽能够通过多个过汽孔31穿过隔板30，进一步便于蒸汽的均匀分散。
进一步地，隔板30上每相邻两个过汽孔31的间距由所在隔板30的中部向两端逐渐减小。由于蒸汽通过进汽口11进入后随流动距离的增长速度会逐渐降低，通过合理排布过汽孔31的间距，可以使蒸汽能够更加均匀的分散，进一步提高烹饪腔13的蒸汽填充效率。
过汽孔31的孔径由所在隔板30的中部向两端逐渐增大。由于蒸汽通过进汽口11进入后随流动距离的增长速度会逐渐降低，通过合理设置过汽孔31的孔径，可以使蒸汽能够更加均匀的分散，进一步提高烹饪腔13的蒸汽填充效率。
图1-图3示出了根据本申请一个具体示例的进汽结构1，每个分汽腔120与多个分汽孔21连通。这样可以使每个分汽腔120内的蒸汽能够通过多个分汽孔21向烹饪腔13分散，从而进一步便于蒸汽的分散，提高烹饪腔13的蒸汽填充效率。
有利地，每个分汽腔120连通的多个分汽孔21中每相邻的两个的间距由所在分汽腔120的中部至两端逐渐减小。由于蒸汽通过进汽口11进入后随流动距离的增长速度会逐渐降低，通过合理排布分汽孔21的间距，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。
更为有利地，每个分汽腔120连通的多个分汽孔21的孔径由所在分汽腔120的中部至两端逐渐增大。由于蒸汽通过进汽口11进入后随流动距离的增长速度会逐渐降低，通过合理设置分汽孔21的孔径，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。
进一步地，在进汽方向上每相邻的两个分汽孔21的间距沿进汽方向逐渐减小。由于蒸汽通过进汽口11进入后随流动距离的增长速度会逐渐降低，通过合理排布分汽孔21的间距，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。
分汽孔21的孔径在进汽方向上逐渐减小。由于蒸汽通过进汽口11进入后随流动距离的增长速度会逐渐降低，通过合理设置分汽孔21的孔径，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。具体地，如图1-图3所示，进汽口11设在所述进汽腔12的至少一个侧板上。这样可以使蒸汽从所述进汽腔12的侧部进入，便于蒸汽气源的设置。进汽腔12位于烹饪腔13的上方。这样蒸汽从分汽孔21排出后，可以通过沉降逐渐向下填充烹饪腔13，从而便于提高烹饪腔13的蒸汽填充效率。具体而言，进汽口可以与蒸汽气源连通。蒸汽气源可以由加热装置提供。
下面描述根据本申请实施例的加热装置。根据本申请实施例的加热装置包括水箱、电极、导电率检测装置和控制器。
电极用于加热水箱内的水。导电率检测装置检测水箱内水的导电率。控制器分别与电极和导电率检测装置电连接以根据所述导电率调节电极的电压。
根据本申请实施例的加热装置，通过设置电极，利用电极对水箱里的水进行加热，相比相关技术中的加热装置，水体本身作为电阻介质被加热，可以减少水垢的堆积，避免影响加热装置的加热效率，避免加热装置堵塞甚至烧毁。并且，由于水质不同，水体作为电阻介质时的导电率也不同，导致相同的电压下水体的加热功率不同，水体的加热功率难以控制。通过设置导电率检测装置和控制器，利用控制器根据导电率调节电极的电压，相比相关技术中的可以便于对加热功率进行控制，避免加热功率过大或过小而影响加热效果。
因此，根据本申请实施例的加热装置具有不易堆积水垢、加热效率高、加热效果好等优点。
具体地，电极为两个且间隔设置。这样可以利用两个电极之间的水体构成电阻介质，利用两个电极对之间的水体通电，直接对两个电极之间的水体进行加热，避免水垢堆积。
可选地，两个电极沿水平方向间隔设置。这样可以便于电极的布置，便于在水位变化时两个电极同时入水或出水。
具体而言，水箱内的水位下降至电极以下时，两个电极不再被水体导通，两个电极的电连接自然断开，避免干烧。由此不仅可以避免干烧，保证加热装置的可靠性，而且可以省去保护装置，降低成本。
更为具体地，电极通过安装座安装在水箱内。这样可以便于将电极安装在水箱内，便于对电极的定向和定位。
在一个具体实施例中，所述安装座位于水箱的底壁，电极沿竖直方向定向。这样可以在水位降低至邻近底壁时电极之间的电连接断开，便于控制水箱的容积。
在另一个具体实施例中，所述安装座位于水箱的侧壁且邻近底壁，电极沿水平方向定向。这样可以在水位降低至邻近底壁时电极之间的电连接断开，便于控制水箱的容积。
具体地，加热装置还包括变频器，控制器通过变频器与电极电连接。由此可以利用变频器调节电极的电压，便于对电极电压的控制。
可选地，导电率检测装置包括TDS检测装置。由此可以根据TDS检测装置反馈水体的导电率，从而根据所需的功率计算电极的电压。
更为具体地，控制器根据所述TDS检测装置的检测值调节电极的电压使电极的电压与所述检测值成正比。这里需要理解的是，“电极的电压与所述检测值成正比”是在不考虑目标功率的情况下。换言之，在目标功率不变的情况下，电极的电压需要与所述检测值成正比。这样可以便于控制加热装置的加热功率，避免加热功率过高或过低而影响加热效果。
水箱上设有蒸汽出口。这样水箱内的水被电极加热后产生的蒸汽可以通过蒸汽出口排出，将蒸汽出口排出的蒸汽进一步导入到烹饪器具的烹饪腔中，可以实现对食物的蒸汽烹饪。
有利地，蒸汽出口位于水箱的上部。这样可以便于控制水箱的最大储水量，便于控制水箱的体积，便于蒸汽的排出。
在一个实施例中，蒸汽出口可以形成在水箱的顶壁上。
在另一个实施例中，蒸汽出口可以形成在水箱的侧壁上且邻近顶壁。

具体地，电极为板状或柱状。这样可以便于对水体进行加热。
下面描述根据本申请实施例的加热装置的工作过程。
当水箱内储水不足时，两个电极之间呈断路，加热装置自动呈断电状态，没有蒸汽产生。当水箱内加入水至电极导通后，加热装置呈导通状态，石墨电极利用水箱内水体本身的电阻，水体本身充当电阻介质，将水体加热产生蒸汽。
同时TDS检测装置检测水的TDS的检测值，反馈给控制器，控制器根据TDS值计算导电率，反映水体的电阻率，并根据目标的功率值，计算出电压值，反馈给变频器调节输出电压。实现不同水硬度条件下，加热体也能变功率调节。

并且，通过使抽气装置和进汽装置在至少一段时间内同时运行，换言之汽路系统至少在一段时间内同时抽气和进汽，相比相关技术中先抽气再进气的技术方案，可以减少用户等待抽气的时间，缩短进汽所需的总时间，提高进汽效率。
具体而言，用于蒸汽烹饪器具时，可以缩短蒸汽填充所需的总时间，减少用户等待时间，提高烹饪效率。因此，根据本申请实施例的汽路系统具有进汽速度快、进汽效率高等优点。
具体地，所述烹饪腔具有抽气孔和进汽孔，抽气装置通过抽气孔与所述烹饪腔连通，进汽装置通过进汽孔与所述烹饪腔连通。这样可以便于进汽装置和抽气装置与箱体的烹饪腔连通。
有利地，进汽孔设在箱体的上部，抽气孔设在箱体的下部。这样可以使进汽孔远离抽气孔，避免抽气装置将刚进入烹饪腔的蒸汽抽出，从而避免影响进汽效率。
更为有利地，进汽孔和抽气孔中的一个设在所述烹饪腔的侧壁且另一个设在所述烹饪腔的后壁。这样可以使进汽孔远离抽气孔，避免抽气装置将刚进入烹饪腔的蒸汽抽出，从而避免影响进汽效率。
具体地，抽气装置在所述烹饪腔烹饪食物的过程中的至少一部分时间内对所述烹饪腔进行抽气。这样可以在烹饪阶段提高汽路系统的进汽效率，从而提高烹饪效率。
在本申请的一个具体实施例中，汽路系统还包括用于检测所述烹饪腔内温度的温度检测装置，所述温度检测装置与抽气装置通讯。这样可以根据烹饪腔内的温度控制抽气装置的启停时机。
具体地，抽气装置在所述温度检测装置的检测值大于等于预定值时停止运行。这样可以在烹饪腔内的温度达到所需温度时停止抽气，避免影响后续烹饪效果。
在本申请的另一个具体实施例中，汽路系统还包括计时装置，所述计时装置在抽气装置运行预定时间后停止抽气装置。由此可以通过计时控制抽气装置的停止时机，避免影响后续的烹饪效果。
具体地，汽路系统还包括控制器，所述控制器分别与进汽装置和抽气装置通讯。这样可以便于控制进汽装置和抽气装置的运行时机。
更为具体地，所述控制器在开始烹饪时控制进汽装置和抽气装置同时运行。换言之，在烹饪器具接收到烹饪指令后，进汽装置和抽气装置同时运行，烹饪腔同时进汽和抽气，从而提高汽路系统的进汽效率。可选地，抽气装置为单向气泵。这样可以便于对烹饪腔进行抽气。
下面描述根据本申请具体实施例的汽路系统的工作过程。
烹饪器具接收到烹饪指令后，进汽装置和抽气装置同时运行，烹饪腔同时进汽和抽气，蒸汽逐渐填充烹饪腔，烹饪腔内的温度随蒸汽的填充逐渐升高，温度检测装置实时检测烹饪腔内的温度，在温度达到预定值时，表明烹饪腔内的蒸汽填充到所需的程度，抽气装置停止运行，避免影响后续烹饪过程。

下面描述根据本申请实施例的烹饪器具的控制方法，包括以下步骤：开始烹饪时，向所述烹饪器具的烹饪腔通入蒸汽，对所述烹饪腔抽气；经过预定时间后停止抽气。
根据本申请实施例的烹饪器具，具有进汽速度快、进汽效率高等优点。
如图4-图7所示，根据本申请的另一些实施例的进汽结构1，箱体10上设有进汽口11。分汽板20上设有多个间隔设置的分汽孔21，分汽板20将箱体10分隔为进汽腔12和烹饪腔13，分汽板20上设有进汽槽22，进汽槽22分别与进汽腔12和进汽口11连通。
具体而言，蒸汽通过进汽口11进入后，在进汽槽22的导向下流动，同时蒸汽在进汽槽22内流动的过程中逐渐进入分汽板20上方的进汽腔12，最后通过分汽板20上的分汽孔21进入烹饪腔13。
根据本申请实施例的进汽结构1，通过设置分汽板20，可以利用分汽板20将箱体10内的空间分隔为进汽腔12和烹饪腔13，这样蒸汽通过进汽口11进入后，可以先在进汽腔12内分散后，再通过多个分汽孔21进入烹饪腔13，使蒸汽均匀分散地进入烹饪腔13中，避免蒸汽过于集中，使蒸汽形成整体的蒸汽层，随蒸汽的填充将空气挤出而不会与空气掺混，便于蒸汽快速充满烹饪腔13，提高蒸汽的填充效率，从而提高进汽结构1的进汽效率，提高烹饪腔13升温速度。并且，通过在分汽板20上设置进汽槽 22，使进汽槽22分别与进汽腔12和进汽口连通，可以利用进汽槽22对蒸汽进行引导，有助于蒸汽在进汽槽22的延伸方向上进行扩散。由此可以使蒸汽能够更加均匀分散地进入进汽腔12，从而进一步便于蒸汽快速充满烹饪腔13，提高蒸汽的填充效率，提高进汽结构1的进汽效率，提高烹饪腔13的升温速度。因此，根据本申请实施例的进汽结构1具有进汽效率高、填充速度快等优点。
下面参考附图描述根据本申请具体实施例的进汽结构1。
在本申请的一些具体实施例中，如图4-图7所示，根据本申请实施例的进汽结构1包括箱体10和分汽板20。具体地，进汽槽22的上表面敞开以与进汽腔12连通(上下方向如图中的箭头所示且仅为了便于表述，并非对于实际设置方向的限定)。这样可以便于进汽槽22与进汽腔12连通，使蒸汽能够更加顺畅均匀地从进汽槽22进入进汽腔12。
更为具体地，如图4-图7所示，进汽口11与进汽槽22的至少一端连通。这样可以便于进汽槽22与进汽口11连通，而且可以使蒸汽能够更加顺畅地进入进汽槽22。
有利地，进汽槽22设在分汽板20的一侧边沿。这样可以便于进汽槽22的设置。
更为有利地，分汽孔21的孔径由靠近进汽槽22至远离进汽槽22的方向逐渐增大。由于蒸汽通过进汽槽22进入进汽腔12后随流动距离的增长速度会逐渐降低，通过合理设置分汽孔21的孔径，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。
进一步地，在靠近进汽槽22至远离进汽槽22的方向上，每相邻两个分汽孔21之间的距离逐渐减小。由于蒸汽通过进汽槽22进入进汽腔12后随流动距离的增长速度会逐渐降低，通过合理排布分汽孔21的间距，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。
可选地，在进汽槽22的长度方向上，分汽孔21的孔径由靠近进汽口11至远离进汽口11的方向逐渐增大。由于蒸汽通过进汽口11进入进汽槽22后随流动距离的增长速度会逐渐降低，通过合理设置分汽孔21的孔径，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。
进一步地，在进汽槽22的长度方向上，每相邻两个分汽孔21的间距由靠近进汽口11至远离进汽口11的方向逐渐减小。由于蒸汽通过进汽口11进入进汽槽22后随流动距离的增长速度会逐渐降低，通过合理设置分汽孔21的孔径，可以使蒸汽更加均匀分散地进入烹饪腔13，进一步提高烹饪腔13的蒸汽填充效率。
如图4-图7示出了根据本申请一个具体示例的进汽结构1。进汽槽22形成在分汽板20的前边沿(前后方向如图中的箭头所示且仅为了便于表述，并非对于实际设置方向的限定)。由此可以便于进汽槽22的设置。具体地，如图2所示，进汽槽22由分汽板20下凹形成。这样可以便于进汽槽22的形成，减少零件数量，简化装配工序。
可选地，如图4-图7所示，进汽口11形成在箱体10的侧壁上。这样可以便于进汽口11的设置，便于进汽口11与蒸汽气源相连。
有利地，进汽口11与进汽槽22的一端连通且朝向另一端。这样可以使蒸汽在进汽槽22内的流动更加顺畅。
更为具体地，如图5，进汽槽22为方槽。这样可以便于进汽槽22适配箱体10结构，便于进汽槽22的设置。进汽腔12位于烹饪腔13的上方。这样蒸汽从分汽孔21排出后，可以通过沉降逐渐向下填充烹饪腔13，从而便于提高烹饪腔13的蒸汽填充效率。
如图8-11所示，根据本申请再一些实施例的进汽结构1，箱体10内具有烹饪腔13以及位于烹饪腔13上方的进汽腔12，烹饪腔13与进汽腔12相连通，以使进汽腔12内的气体能够流进烹饪腔13内，进气管2的至少一部分伸入到进汽腔12内，且进气管2的至少一部分上开设有排气孔201，以使从蒸汽发生器排入到进气管2内的蒸汽能够通过排气孔201排入到进汽腔12内。也就是说，蒸汽通过进气管2进入进汽结构1内，并通过进气管2上开设的排气孔201排入到进汽腔12中，由于从进气管2进入的蒸汽的气流在进汽腔12内得到了扩散与减速，从而使得从进汽腔12进入到烹饪腔13内的蒸汽流动速度能够得到降低，并且，蒸汽会在进汽腔12内形成一个稳定的蒸汽层，且该蒸汽层能够缓慢的由上至下运动，以稳定的将烹饪腔13内的空气从烹饪腔13的下方排出，因此降低了蒸汽与空气的混合程度，以提高了空气的排出速度，从而提高了烹饪腔13的升温效率。
由于蒸汽的密度低于空气的密度，因此，将进气管2以及进汽腔12设置在烹饪腔13的上侧，以使 蒸汽能够由上至下的填充满整个进汽结构1，并同时将烹饪腔13内原有的空气排出进汽结构1，以进一步降低蒸汽与空气的混合程度，提高蒸汽填充烹饪腔13的速度，从而达到提高烹饪腔13内环境升温速度，减少进汽结构1的烹饪时间的目的。
根据本申请实施例的进汽结构1，该进汽结构1能够降低蒸汽流入烹饪腔13的流速，能够在烹饪的初始阶段降低蒸汽与空气的混合程度，以提高了蒸汽填充烹饪腔13的速度，从而使烹饪腔13内的环境温度能够快速提升，以减少进汽结构1烹饪食物的烹饪时间，进而达到了快速烹煮的目的。
如图8和图10所示，进汽结构1还包括：分汽板20，分汽板20设置在烹饪腔13与进汽腔12之间，以将烹饪腔13与进汽腔12分割开。其中，分汽板20与箱体10的顶壁11c之间限定出进汽腔12，以使进汽腔12位于整个箱体10的最上端，且分汽板20上开设有分汽孔21，以连通进汽腔12与烹饪腔13，从而使进汽腔12内的蒸汽能够通过分汽孔21进入到烹饪腔13内，也就是说，在进汽腔12内形成的蒸汽层需要进一步穿过分汽板20上开设的分汽孔21才能够向下运动，因此，进一步降低了蒸汽进入烹饪腔13内的流动速度，以进一步降低了蒸汽与空气的混合程度，从而进一步提高了蒸汽填充烹饪腔13的速度。
其中，分汽板20可整体铸造成型，即分汽孔21可直接形成在分汽板20上，或者采用冲压的加工工艺在分汽板20上加工出分汽孔21。
进一步，参照图10，分汽板20可以为多层，多层分汽板20上下间隔开设置，其中，位于最下层的分汽板20与顶壁11c之间限定出进汽腔12。由此，使蒸汽层在向下运动的过程中需要经过多层分汽板20的减速，以进一步大幅度降低了蒸汽流入烹饪腔13内的流动速度，从而进一步大幅度提高了蒸汽填充烹饪腔13的速度，以便于实现进汽结构1快速烹煮的目的。
再进一步，进气管2位于最上层的分汽板20与顶壁之间，以使蒸汽层在向下运动的过程中能够依次经过多个分汽板20，以在最大程度上利用分汽板20降低蒸汽的流动速度。
根据本申请的一些实施例，相邻两层分汽板20上的分汽孔21错开设置，换言之，相邻两层分汽板20上的分汽孔21不正对设置。由此，从上层分汽板20的分汽孔21流动到下层分汽板20的蒸汽气流会被下层分汽板20的板体阻挡，经过进一步的减速后再通过下层分汽板20的分汽孔21以流入下一层，以实现多层分汽板20之间对蒸汽气流的逐级减速，从而利用多层分汽板20的阻隔作用达到更好的减速蒸汽气流流速的效果。
结合图8和图10所示实施例，每层分汽板20上具有多个分汽孔21，多个分汽孔21均匀分布，以使在蒸汽层向下运动的过程中，同一平面内，各处的蒸汽密度和蒸汽流速均匀一致，以确保蒸汽层能够稳定的向下运动，以稳定的将空气排出烹饪腔13，从而提高蒸汽填充烹饪腔13的速度，并且还能够使烹饪腔13内各处的蒸汽密度更均匀，以确保烹饪腔13内各处都能够被均匀加热，进而使进汽结构1对食物的加热效果更好。
进一步，排气孔201与分汽孔21错开设置，以避免从排气孔201进入到进汽腔12的蒸汽直接冲击分汽孔21并从分汽孔21直接流入下一层分汽板20的夹层而导致的蒸汽在进汽腔12内无法形成稳定的蒸汽层，进而避免蒸汽流动速度无法被分汽板20降低，因此，将排气孔201与分汽孔21错开设置以确保在进汽腔12内能够稳定的形成蒸汽层，以便于进一步降低蒸汽流入烹饪腔13内的流动速度。
结合图9和图10所示实施例，顶壁11c的至少一部分向外突出以形成突出部111，进气管2从突出部111的周壁向内穿设，以使蒸汽夹层腔和进气管2的设置均不占用进汽结构1用于烹饪的烹饪空间，从而使烹饪腔13能够设置的更大，以能够进一步提升进汽结构1的容积。
结合图8和图11所示实施例，进气管2为多根，以使从蒸汽发生器内流出的蒸汽能够被多根进气管2分流，以降低蒸汽流入进汽腔12内的流速，并且，多根进气管2间隔开设置，且多根进气管2上的排气孔201相互错开设置，以避免相邻两根进气管2上的排气孔201分别排出的蒸汽互相冲击而产生流动速度较快的乱流，进而使进汽腔12内能够形成稳定的蒸汽层。
进一步，多根进气管2从周壁的不同方向向箱体10内穿设，以使进气管2排出的蒸汽能够更均匀的填充满进汽腔12，从而使进汽腔12内的蒸汽密度更均匀，以便于形成稳定的蒸汽层，进而能够使烹饪腔13内各处的蒸汽密度更均匀，以确保烹饪腔13内各处的均匀加热，以使进汽结构1对食物的加热效果更好。
如图11所示，多根进气管2与分汽板20之间的距离分别相等，以使同一平面内的蒸汽流动速度趋于一致，从而使蒸汽能够均匀填充满进汽腔12，并在蒸汽夹层腔内形成稳定的蒸汽层，进而使蒸汽层能够均匀稳定的穿过分汽板20。
进一步，每根进气管2上的排气孔201为多个，以在进气管2向进汽腔12内排入蒸汽的过程中将蒸汽分流，并提高进气管2排出的蒸汽的覆盖面积，从而能够进一步降低蒸汽的流动速度，以达到降低蒸汽与空气的混合程度，提高蒸汽填充烹饪腔13的速度的目的，并且，多个排气孔201的至少一部分开设在进气管2的周壁上，以便于更多个排气孔201的设置。
再进一步，位于进气管2的周壁上的部分排气孔201朝向箱体10的顶壁开设，以使从排气孔201流入的蒸汽气流首先经过顶壁的阻挡，速度减缓后再向下流动，以进一步降低蒸汽的流速。
作为一种优选的实施例，参照图11，位于进气管2的周壁上的部分排气孔201等间距分布，以使从各个排气孔201排出的蒸汽量更均匀，从而使进入烹饪腔13内各处的蒸汽的密度与流速更均匀，进而使烹饪腔13各处能够均匀升温，以使进汽结构1具有更好的加热性能。
根据本申请的一些实施例，由于进气管2的靠近进气端的蒸汽流动速度较快，而远离进气端的蒸汽流动速度较慢，即随着进气口11距离进气端的距离越远，蒸汽的流速越慢，因此，将靠近进气管2的进气端的排气孔201的直径设置的小于远离进气管2的进气端的排气孔201的直径，以使从各个排气孔201流出的蒸汽的流动速度相同，从而使同一平面内各个位置上的蒸汽流动速度均匀一致，以使蒸汽在进汽腔12内能够形成稳定的蒸汽层，进而使蒸汽层能够均匀稳定的穿过分汽板20，以进一步降低蒸汽与空气的混合程度，提高蒸汽填充烹饪腔13的速度，并且还能够使烹饪腔13内各处的蒸汽密度更均匀，以确保烹饪腔13内各处能够均匀加热，以使进汽结构1对食物的加热效果更好。
参照图11，多根进气管2在同一横向平面内平齐设置(其中，横向为垂直于箱体10的高度方向的方向)，且多根进气管2平行设置，以使同一平面内的蒸汽流动速度趋于一致，从而使蒸汽能够进一步形成稳定的蒸汽层，以更便于均匀填充烹饪腔13，并稳定的将烹饪腔13内的空气排出。
根据本申请的一些实施例，蒸汽发生器由水管与加热件构成，并在水管内由液态水转化为水蒸汽，并将水蒸汽输送到蒸汽家电内部，以使加热后的水蒸汽能够对蒸汽家电内部的食物进行加热烹煮。可选的，加热件设置在水管的内部和/或外部以对水管进行加热，以通过加热水管将水管内的液态水加热或直接对液态水进行加热，使其经过加热后由液态水转化为水蒸汽。即加热件可以设置在水管的内部或外部，或者同时设置在水管的内部和外部，以便于提高加热效率，进而能够提高水蒸汽的产生效率。
进一步，水管构造为可随其所受温度的变化而伸缩的形式，由于在蒸汽发生器的运行过程中，水管会产生温度变化，即加热器持续加热水管，会使水管的温度持续升高，而当水管内流入凉水时，水管的温度又会短暂降低，因此水管会伴随着温度的变化而实现不断的自动伸缩，又由于水管的伸缩会改变水管的内壁面积，因此堆积在水管内壁上的水垢在水管的伸缩过程中会从水管内壁上脱落，并伴随水流的流动排出到水管外，因此无需人工加入柠檬酸等清洁物质去清洗水管内的水垢，从而使得蒸汽发生器内水垢的清洁更便捷，避免了因水垢在水管内的堆积而造成的蒸汽发生器的损坏。
并且，由于本申请实施例采用了加热件配合水管的流道型蒸汽发生器的形式，因此可使整体结构较扁平，整体尺寸较小，对安装空间要求更低，更便于布置，能够满足水平或侧立等安装需求。
根据本申请的一些实施例，水管适于随其所受温度的升高而伸长，且随其所受温度的降低而缩短，也就是说，在蒸汽发生器的运行过程中，水管在加热件的加热作用下温度逐渐升高，水管会随所受温度的逐渐升高而逐渐伸长，而当蒸汽发生器停止加热后，加热件停止对水管进行加热，水管的温度会逐渐降低直至室温，水管则会随温度的降低而逐渐缩短，或者，在正常加热时，水管内的水流会快速的带走水管的热量，水管会随所受温度的骤降而缩短。
由此，在蒸汽发生器的运行过程中，水管会进行多次形状伸缩，并在伸缩过程中脱离内壁附着的水垢，以使水垢能够伴随水流一起排出水管，从而避免了水垢的堆积，进而提高了蒸汽发生器的安全性。
根据本申请的一些实施例，水管构造为记忆合金件。记忆合金是由两种以上金属元素所构成的材料，记忆合金件通过热弹性与马氏体相变及其逆变而具有形状记忆效应。具体的，水管具有双程记忆效应，以使水管在加热后能够在记忆合金件的形状记忆效应下伸长，并在温度降低后缩短，从而使水管能够在伸长与缩短的过程中脱离内壁附着的水垢。
优选的，水管构造为铜锌铝形状记忆合金件。由于铜锌铝形状记忆合金件的价格较低，并且性质较稳定，在高温加热过程中不会产生有害物质，因此，采用铜锌铝形状记忆合金制造水管能够降低水管的制造成本，以及提高蒸汽发生器的安全性。当然，本申请实施例不仅限于此，水管还可采用铜锌锡形状记忆合金、铜锌硅形状记忆合金或铁锰硅形状记忆合金中的一种或多种制造而成。
根据本申请的一些实施例，加热件包括：加热管，其中，水管构造为圆管，且加热管螺旋缠绕在圆管的外侧，以使加热管与圆管之间的接触面积更大，从而能够确保加热管对圆管的加热效果。并且，加热管螺旋缠绕在圆管的外侧，能够使圆管的各处受热更均匀，以避免由于圆管受热不均而导致的水管在受热伸长过程中出现变形，从而提高了蒸汽发生器的设置安全性。
根据本申请的另一些实施例，加热件包括：加热板，水管构造为方管，加热板贴附在方管的至少一侧壁上，加热板通过对方管的侧壁进行加热以加热方管内的液态水，以使方管内的液态水能够在方管内由液态转化为水蒸汽，并输送到蒸汽家电内部。并且，由于加热板与方管组成的蒸汽发生器的整体结构可以为扁平状的方形结构，而且能够贴附在蒸汽家电的内部空间的内壁上设置，因此使得蒸汽家电的整体结构更紧凑，提高了蒸汽家电内部空间的利用率。
根据本申请的一些实施例，加热件与水管之间设置有导热层，以使水管的受热更均匀，避免由于水管受热不均而导致的水管在受热伸长过程中出现变形的情况，从而进一步的提高了蒸汽发生器的设置安全性。
作为一种优选的实施例，加热件包括：电磁感应线圈，电磁感应线圈套设在水管的外侧，以通过电磁感应加热原理对水管进行加热。由此，不仅加热效果更好，而且可使结构较简单，造价更低。
根据本申请的一些实施例，水管的内壁构造为光滑内壁，以使堆积在水管内壁上的水垢更易脱落，从而使得水垢能够在水管伸缩的过程中完全脱离水管，以进一步提升了蒸汽发生器的除垢效果。
在另一些实施例中，水管可构造为电阻管，电阻管根据本身材料特性具有一定的电阻值，能够将电能转化为热能，供电装置能够向电阻管提供电能，以使电阻管能够自身产热。电阻管内具有液体流动空间，且电阻管内的液体流动空间一端与外界液体源连接，另一端与蒸汽发生器的出气通道连接，液态水在电阻管内的液体流动空间内由液态转化为水蒸汽，供电装置与电阻管电连接，以能够向电阻管供电而使电阻管产热。在供电装置向电阻管供电后，电阻管能够将电能转化为热能，且电阻管产生的热量能够直接加热液体流动空间内的液态水，以使从外界液体源流入液体流动空间内的液态水在受热后能够由液态转化为水蒸汽，并将转化后的水蒸汽从蒸汽发生器的出气通道输送到蒸汽家电内部，以使加热后的水蒸汽能够对蒸汽家电内部的食物进行加热烹煮。
根据本申请的一些实施例，供电装置包括：电源和供电导线，电源可以为直流电源也可以为交流电源，供电导线电连接在电源与电阻管之间，以将电源的电流传输到电阻管两端，从而利用电流流过电阻管产生的热效应加热液态水，使液态水转化为水蒸汽。
进一步，供电导线为两根，两根供电导线分别连接在电阻管在延伸方向上的两个最外端。即两根供电导线适于分别连接在电阻管的进液端和出气端上，以使电阻管的全部电阻材料都能够受到两端电压的加持，使整个电阻管都能够在电源的作用下产生热量，从而使得电阻管能够具有最大的发热面积，进而使得电阻管的加热效果更好。由此，提高了电阻管的加热效率，进而提升了蒸汽发生器的蒸汽生产效率。
具体的，其中一条供电导线连接在靠近水管与电阻管的连接处的位置，另一条供电导线连接在靠近电阻管与蒸汽发生器的出气通道连接处的位置。由此，使得电阻管整体均能够发热，以使其具有最大的发热面积。
根据本申请的一些实施例，电阻管的外侧设置有绝缘保护层，其中，绝缘保护层能够起到有效的绝缘作用。由此，当电阻管出现漏液或其他故障时，绝缘保护层能够避免电阻管发生短路，以能够提高蒸汽发生器的运行稳定性，并且还可避免电阻管与周边件出现搭接的情况而发生短路的现象。
进一步，电阻管的电阻值与电阻管的材料有关，电阻管可构造为金属管、硅胶管或石墨管，其中，金属管、硅胶管和石墨管的制造材料价格较为低廉，可降低蒸汽发生器的整体造价，并且具有较好的电阻率，且质地较坚硬，不易损坏，因此使电阻管具有更好的加热效果和设置稳定性。
根据本申请的一些实施例，电阻管的电阻值还与电阻管的管长和壁厚有关，具体的，电阻管的壁厚越薄，电阻越大，功率越小，电阻管的管长越长，电阻越大，功率越小，因此，使电阻管的壁厚为D， 0.1mm≤D≤10mm，也就是说，电阻管的壁厚控制在0.1mm到10mm之间，以在保证电阻管的整体强度的前提下使电阻管具有更大的电阻值，以使电阻管能够释放更多的热量用以加热液态水产生水蒸汽。
进一步，使电阻管的长度为L，5cm≤L≤3m，也就是说，电阻管1的长度控制在5cm到3m之间，以在保证电阻管的整体重量以及体积大小在合理范围内的前提下使电阻管具有更大的电阻值，以使电阻管能够释放更多的热量用以加热液态水产生水蒸汽。
根据本申请的一些实施例，供电导线上设置有通断保护装置，通断保护装置能够保证蒸汽发生器的运行安全性。即在水盒内的水量不足或电路出现短路等异常情况发生时，通断保护装置适于自动断开电源与电阻管之间的电连接，以避免电源持续为电阻管供电而造成的电路损坏或热失控等危险情况的发生，从而能够提高蒸汽家电的可靠性以及安全性。
根据本申请的一些实施例，为了能够便捷的调整蒸汽发生器所产生蒸汽的温度与效率，以实现不同烹饪模式的自由切换，本申请实施例在供电导线上还设置有电压调节装置，以通过对电阻管两端的电压进行调节来调整电阻管的发热功率，从而达到了改变电阻管产生水蒸汽的效率以及产生的水蒸汽的温度的目的。
如图12-16所示，根据本申请又一些实施例的进汽结构1，通过在箱体10内构造出进汽腔12和烹饪腔13形成蒸汽层，蒸汽均匀下压空气将氧气快速排出，达到无氧烹饪的目的，从而实现食品健康，利于营养吸收。
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。
如图12至图16所示，根据本申请实施例的进汽结构1，包括：箱体10、产蒸汽组件，箱体10内具有进汽腔12和烹饪腔13，由此，蒸汽进入箱体10时可以先集中于进汽腔12，随后通过进汽腔12进入到烹饪腔13，起到减缓蒸汽流速的效果，避免蒸汽直接卷吸空气，从而避免蒸汽与烹饪腔13内空气进行强烈的参混。具体地，进汽腔12和烹饪腔13由分隔结构隔开，且分汽板20上设有间隔排布的多个分汽孔21，分汽孔21接通进汽腔12和烹饪腔13；产蒸汽组件与箱体10相连并与进汽腔12连通。通过在进汽腔12和烹饪腔13之间设置分汽板20，实现将两个腔体分隔开的效果，且结构简单易于构造，在分汽板20上设置多个分汽孔21可以连通进汽腔12和烹饪腔13，使得进汽腔12中的蒸汽可以进入烹饪腔13以加热烹饪腔13。
另外，间隔布置的多个分汽孔21可以在蒸汽从进汽腔12进入烹饪腔13时，对蒸汽起到缓冲和分散作用，使得出汽量较多且出汽均匀，从而形成蒸汽层，均匀地压出烹饪腔13中的空气，将氧气快速排出，以加热烹饪腔13，且可以达到无氧烹饪的目的，以利于营养吸收。
根据本申请实施例的进汽结构1，通过在箱体10腔体内设置具有多个分汽孔21的分汽板20。使分汽板20可以分隔出进汽腔12和烹饪腔13，使得蒸汽在烹饪腔13体时可以形成蒸汽层，利于排出烹饪腔13内氧气，以提高烹饪效果，利于提升饮食健康。
实际使用时，通过设置分汽板20可以在箱体10的腔体中分隔出进汽腔12和烹饪腔13，蒸汽先进入进汽腔12中，在进汽腔12中的蒸汽受到分汽板20的阻隔，不能直接进入烹饪腔13中，从而起到减缓蒸汽流速的效果。在进汽腔12中得到缓冲的蒸汽从多个间隔设置的分汽孔21进入烹饪腔13，使得蒸汽在进入烹饪腔13时被分散开，提高蒸汽进入烹饪腔13的均匀性，且多个分汽孔21可以提高出汽量，形成蒸汽层，随着出汽不断增加，蒸汽层厚度增加，可以快速完全的将空气(氧气)排出烹饪腔13，在箱体10内实现无氧烹饪环境。
结合图15，可选地，进汽腔12与烹饪腔13沿上下方向相对，且进汽腔12设于烹饪腔13的顶部或上方，以利于利用蒸汽与空气的密度差原理，使蒸汽下压空气，利于排出空气。另外，烹饪腔13可以放置食物，使食物在烹饪腔13中被加热或进行食物烹饪，因此，烹饪腔13位于箱体10下部，还起到利于用户操作的效果。
具体而言，可以在烹饪腔13的顶部设置隔板或其他结构，将烹饪腔13的顶部分离开，从而形成进汽腔12。也可以在烹饪腔13的上方，也就是在烹饪腔13的外侧设置进汽腔12，例如，在烹饪腔13的外侧设置盖体11b，从而在盖体11b和烹饪腔13的顶壁之间构造出进汽腔12。可选地，进汽腔12也可 以位于烹饪腔13下方，以利用高温蒸汽易向上升的原理，从而提高加热效果。具体地，蒸汽进入进汽腔12中，蒸汽流速得到缓冲和减缓，蒸汽再经过分汽孔21进入烹饪腔13中。
可选地，分汽板20的水平投影面积与烹饪腔13的水平截面面积的比值不小于0.5，也就是说，分汽板20的在箱体10中的尺寸可以尽量大些，以提高分隔效果，分汽板20的尺寸与烹饪腔13的横截面积之间的尺寸差距可以尽量减小，以提高加热效果，且易于构造，利于节约成本。进一步地，多个分汽孔21在分汽板20上均匀间隔排布并邻近分汽板20的周沿，以利于蒸汽均匀排出，提高出汽量，利于形成蒸汽层。
可选地，也可以是在分汽板20上设置成多个微孔，蒸汽进入进汽腔12后扩散，扩散过程中可以从多个微孔进入烹饪腔13，以减缓蒸汽流速，提高出汽均匀性，提高排气效果。
可选地，分汽孔21的周沿可以连接有导风筒，导风筒连接分汽孔21的周沿，且导风筒与分汽孔21的出风方向同向延伸或具有预定角度的夹角。通过在分汽孔21处设置导风筒，使得蒸汽可以从导风筒排出，导风筒可以起到一定的引导效果，蒸汽在蒸汽腔中流通从分汽孔21排出时，可能需要在导风筒中改变方向，从而进一步起到减缓流速的效果，提高蒸汽进入设备腔体时的均匀性，提高烹饪效果。其中，导风筒与分汽孔21可以是一体构成的，以便于制造。也可以是，导风筒与分汽孔21是分体构成的，以便于维修和更换，例如导风筒与分汽孔21周沿配合的位置的外周设有螺纹，装配时通过螺纹连接将导风筒安装于装置上，也可以是通过螺钉螺栓配合连接的方式。
结合图2至图5，可选地，分汽孔21被构造成自上而下地从进汽腔12排往烹饪腔13，结合高温蒸汽的密度低的原理，使得进入到烹饪腔13内的蒸汽构造成类似蒸汽墙的结构，逐渐下压，以便于将烹饪腔13内的空气快速地排出的效果。进一步地，产蒸汽组件的出口的出汽方向与分汽孔21垂直或具有预定角度的夹角，以使蒸汽进入进汽腔12时受到一定阻挡，利于降低蒸汽流速，避免蒸汽直接以较快的流速进入烹饪腔13中与空气参混。具体的，当出汽方向与分汽孔21垂直时，如出汽方向竖直向下，分汽孔21水平布置，如此，蒸汽到达分汽板20时受到阻挡，气流速度得到减缓，使得蒸汽以较为稳定的速度从分汽孔21中排出。
结合图13，可选地，箱体10包括壳体11a和分汽板20，分汽板20设于壳体11a内，且分汽板20在壳体11a内分隔出进汽腔12和烹饪腔13，分汽板20构造成分汽板20，多个分汽孔21设于分汽板20上。也就是说，分汽板20将箱体10内的空间分隔开，分汽板20上表面与壳体11a构造出进汽腔12，分汽板20下表面与壳体11a构造出烹饪腔13，通过在分汽板20上设置多个分汽孔21以连通进汽腔12和烹饪腔13，其中，分汽板20一方面可以起到分隔、阻挡蒸汽的作用，另一方面还可以使蒸汽以较为均匀稳定的速度进入烹饪腔13，以提高对烹饪腔13的加热效果且利于排出氧气。
可选地，分汽板20水平设于壳体11a内的顶部，可以使箱体10内烹饪腔13具有较大的空间，利于用户使用，具体地，分汽板20与壳体11a顶壁11c的内侧面之间构造出进汽腔12，利于简化结构，利于蒸汽逐步下沉排出空气。
结合图2，根据本申请的一个具体实施例的进汽结构1，壳体11a呈中空的方形形状，壳体11a顶部构造出向上的凸起的凸包结构14，凸包结构14呈方形，分汽板20水平设置于壳体11a内，具体地，分汽板20设置于凸包结构14的正下方，将壳体11a内部隔开成两部分，即分汽板20上表面与凸包结构14内壁构成进汽腔12，分汽板20下表面与壳体11a内壁构成烹饪腔13，进汽腔12和烹饪腔13直接通过分汽孔21连通。分汽孔21可以设置成在分汽板20上呈阵列排布的形式，以提高出汽均匀性。更为具体地，分汽板20与壳体11a可以为一体构成的，也可以是分汽板20插接于壳体11a内壁，以便于拆卸、更换和清洁，如在壳体11a内壁设置凹槽，在分汽板20周沿设置于凹槽相配合的凸部，以将分汽板20水平插接于壳体11a内。
结合图3，可选地，箱体10包括壳体11a和盖体11b，壳体11a内构造出烹饪腔13，盖体11b盖在壳体11a外侧，盖体11b与壳体11a的外表面之间构造出进汽腔12，壳体11a上与盖体11b对应的部分构造成分汽板20，多个分汽孔21设于壳体11a的与盖体11b对应的部分上。也就是说，分汽板20也可以直接设置于壳体11a上，以利于构造，利于简化结构，盖体11b盖在外壳外侧，在盖体11b与外壳之间形成进汽腔12，当需要查看进汽腔12内部时，仅需要打开盖体11b即可。
可选地，壳体11a上与盖体11b对应的部分朝向壳体11a外突出并嵌入到盖体11b内，以提高盖体 11b与壳体11a配合的紧密性，利于控制进汽腔12的空间，增大烹饪腔13的使用空间，为用户使用装置提供便利。
可选地，壳体11a包括顶壁11c，多个分汽孔21设于顶壁11c上，盖体11b盖在顶壁11c外侧以在盖体11b内构造出进汽腔12，且盖体11b覆盖多个分汽孔21，以使进入进汽腔12中的蒸汽可以通过分汽孔21进入烹饪腔13中，以提高加热效果，利于快速排除氧气。
结合图14，根据本申请的另一个具体实施例的进汽结构1，壳体11a呈中空的方形形状，壳体11a的顶壁11c向上凸起，且顶壁11c上间隔布置多个分汽孔21，盖体11b盖在壳体11a向上凸起的顶壁11c外侧，在顶壁11c与盖体11b之间构造出进汽腔12，其中，顶壁11c被构造成向外突出的方形凸起结构，多个分汽孔21呈阵列布置在凸起结构的表面，凸起结构嵌入到盖体11b内，安装时，盖体11b的下周沿与顶壁11c的外周沿向配合以封盖箱体10。
需要说明的是，本申请中主要以将分汽孔21呈圆形形状及多个分汽孔21呈阵列布置为例进行说明，但是这并非是对本申请保护范围的限制，本申请中也可以将分汽孔21的形状及排布方式稍加改变，只要能达到减缓蒸汽流速的效果即可。例如，分汽孔21可以为长条形的，或者分汽孔21的大小可以不相同等。
可选地，产蒸汽组件包括：水盒6、水泵3和蒸汽发生器4，水泵3与水盒6连通，蒸汽发生器4分别与水泵3和箱体10相连，即水泵3分别连接水盒6和蒸汽发生器4，使用时，水泵3从水盒6中抽取水送入蒸汽发生器4中，蒸汽发生器4将水加热成蒸汽送入箱体10中，以对箱体10进行加热。结合图15，水盒6与水泵3之间通过管道5连接，水泵3与蒸汽发生器4之间通过管道5连接，蒸汽发生器4与箱体10上部通过管道5连接，以将蒸汽输送至箱体10的进汽腔12中。另外，管道5向上延伸至箱体10的顶部，由于高温蒸汽易上升，因此管道5向上延伸利于蒸汽输送。
下面参照附图描述本申请一个具体实施例的进汽结构1。
结合图12至图16，根据本申请实施例的进汽结构1，包括：箱体10、水盒6、水泵3、蒸汽发生器4和管道5。具体地，水泵3分别通过管道5与水盒6和蒸汽发生器4连接，蒸汽发生器4产生的蒸汽通过管道5输送至箱体10顶部。箱体10内具有进汽腔12、烹饪腔13和分汽板20，其中分汽板20上间隔布置有多个分汽孔21。
结合图15和图16，更为具体地，水泵3将水盒6内的水打入蒸汽发生器4，蒸汽发生器4将水汽化成蒸汽b喷入箱体10顶部的进汽腔12内，通过分汽板20结构分汽孔21排出到烹饪腔13的蒸汽形成均匀的蒸汽层c，随着蒸汽层c厚度的增加，快速完全的将空气a(氧气)排出烹饪腔13，在箱体10内实现无氧烹饪环境。进汽腔12设置在箱体10顶部，一端连接蒸汽发生器4出汽口，一端通过分汽板20的分汽孔21将蒸汽通入烹饪腔13内。其中，蒸汽的密度为0.6kg/m3，空气的密度为1.293kg/m3，即蒸汽的密度小于空气密度，蒸汽比空气轻，会浮于箱体10内的顶部空间。参见图16，同时为保证排除空气a的效果，要在箱体10的腔体顶部设置具有分汽孔21的分汽板20，蒸汽b通入进汽腔12后，通过具有多个分汽孔21的分汽板20从进汽腔12中排出，形成均匀的蒸汽层c，在蒸汽量不断增加的情况下，蒸汽层c不断加厚，挤压空气层下移，将空气a快速完全的排出。如此，利用蒸汽与空气的密度差原理，通过在箱体10内构造出进汽腔12和烹饪腔13，形成蒸汽层c，均匀下压空气将空气(氧气)快速排出，形成无氧烹饪环境，利于快速加热，达到无氧烹饪的目的。而相关技术中，加热系统包括水盒6’、水泵3’、蒸汽发生器4’、腔体10’。蒸汽发生器4’和腔体10’通过管道5’连接，腔体侧壁开孔连接进汽管道，参见图17。这种进汽方式会导致进汽流速较高，蒸汽与空气强烈的卷吸参混，空气与蒸汽充分混合，无法快速并彻底地将氧气排出。导致相关技术中腔体内存在氧气的两个主要原因导致为：1、蒸汽流速快，卷吸空气，导致两者参混(混合)，无法分离排出；2、蒸汽密度比空气密度低，喷入腔体后会迅速扩散到腔体内各个地方。也就是说，相关技术中，单边进汽的方式容易导致蒸汽与空气强烈的参混，而无法快速彻底地将氧气排出，导致食品营养元素减少，不利于饮食健康。
