本发明的冷藏冷冻装置除了具有普通储物用的冷藏间室和冷冻间室之外，还特别地具有熟成间室，用户可以直接将待熟成物放置在熟成间室中熟成，丰富了冷藏冷冻装置的功能。并且，本申请将熟成间室设置成通过熟成送风口选择性地与冷藏间室和/或冷冻间室连通，由此，可选择性向熟成间室内只输送冷藏间室内的气流(此时可降低熟成间室湿度)、或只输送冷冻间室内的气流(此时可快速降低熟成间室温度和湿度)、或同时输送冷藏间室和冷冻间室内的气流(此时可以较缓地降低熟成间室温度)、或均不输送冷藏间室和冷冻间室内的气流(此时可以通过内循环风机驱动熟成间室内的气流循环流动)，从而确保了熟成间室始终具有合适的温度、湿度和持续的送风，确保了待熟成物的熟成环境，提高了待熟成物的熟成效率和熟成效果。
进一步地，熟成间室分别通过冷藏送风风道和冷冻送风风道与冷藏间室和冷冻间室连通，且经由冷藏送风风道送入熟成间室的气流量和经冷冻送风风道送入熟成间室的气流量均可调，也就是说，送入熟成间室内的来自冷藏间室的气流量可调，送入熟成间室的来自冷冻间室的气流量也可调，由此，可通过对来自冷藏间室的气流量和来自冷冻间室的气流量的调节进一步提高熟成间室内温湿度的控制精确度。
进一步地，熟成间室内设有熟成罩壳，熟成罩壳内限定有熟成腔，熟成罩壳的顶板上设有多个吹风口，多个吹风口在气流流动方向上的排布密度递增，可通过吹风口的排布密度递增的方式弥补气流流速在气流流动方向上递减的缺陷，提高了熟成腔在平行于气流流动方向的纵向上各处的送风均匀性。多个吹风口在垂直于气流流动方向的横向上的排布密度均匀，由此，提高了熟成腔在横向上各处的送风均匀性。可见，本发明通过对吹风口的位置、数量和密度的设置实现风幕式送风，提高了熟成腔内各处的送风均匀性，确保了待熟成物具有均匀的熟成效果。

具体实施方式
本发明首先提供一种冷藏冷冻装置，图1是根据本发明一个实施例的冷藏冷冻装置的示意性结构图，图2是根据本发明一个实施例的冷藏冷冻装置的示意性剖视图，图3是图2中部分A的示意性放大图。参见图1至图3，本发明的冷藏冷冻装置1包括箱体10，箱体10内限定有用于储存物品的冷藏间室11和冷冻间室12、以及用于供待熟成物在其内熟成的熟成间室13。熟成间室13具有允许外部气流流入其中的熟成送风口131和允许其内部的气流流出的熟成出风口132，以便于调节熟成间室13内的熟成环境。
本发明的冷藏冷冻装置1除了具有普通储物用的冷藏间室11和冷冻间室12之外，还特别地具有熟成间室13，用户可以直接将待熟成物放置在熟成间室13中熟成，丰富了冷藏冷冻装置1的功能。
申请人认识到，当冷藏冷冻装置设1置有熟成间室13后，虽然可以利用蒸发器室内的冷却气流实现熟成间室13的温度控制，然而，待熟成物(尤其是肉类食物)的表面需要持续不断的送风，并且蒸发器室内的冷却气流的温度和湿度都比较低，这就决定了不能将蒸发器室内的冷却气流连续不断地送往熟成间室，显然并不能满足待熟成物对温度、湿度和表面风速的综合要求，从而达不到熟成的效果。
为此，本发明进一步将熟成送风口131设置成选择性地与冷藏间室11和/或冷冻间室12连通，并且冷藏冷冻装置1还设计了内循环风机23，内循环风机23配置成受控地促使熟成间室13内的气流循环流过待熟成物的表面。也就是说，熟成间室13可以通过熟成送风口131与冷藏间室11和冷冻间室12中的其中一个间室连通，也可以同时与冷藏间室11和冷冻间室12连通，还可以不与冷藏间室11和冷冻间室12中的任何一个连通。
图4是根据本发明一个实施例的仅向熟成间室内引入冷藏间室气流的气流流动示意图，图5是根据本发明一个实施例的仅向熟成间室内引入冷冻间室气流的气流流动示意 图，图6是根据本发明一个实施例的向熟成间室内同时引入冷藏间室气流和冷冻间室气流的气流流动示意图，图7是根据本发明一个实施例的熟成间室的气流内循环时的气流流动示意图。参见图4至图7，不管熟成间室13是否与其他间室连通，不管是否有其他间室的气流流入熟成间室13，都有气流循环流经熟成间室13，从而确保待熟成物的表面具有持续的送风，提高了待熟成物的熟成效果。
由此，可选择性向熟成间室13内只输送冷藏间室11内的气流(此时可降低熟成间室13的湿度)、或只输送冷冻间室12内的气流(此时可快速降低熟成间室13的温度和湿度)、或同时输送冷藏间室11和冷冻间室12内的气流(此时可以较缓地降低熟成间室13的温度)、或均不输送冷藏间室11和冷冻间室12内的气流(此时可以通过内循环风机23驱动熟成间室13内的气流循环流动)，从而确保了熟成间室11始终具有合适的温度、湿度和持续的送风，确保了待熟成物的熟成环境，提高了待熟成物的熟成效率和熟成效果。
具体地，内循环风机23可以设置在熟成间室13的内部，也可以设置在处于熟成间室13外部的风道内，只要能够驱动熟成间室13内的气流循环流动即可。例如，熟成送风口131和熟成送风口132之间可以设有内循环风道133，内循环风机23设置在该内循环风道133内。参见图7，当内循环风机23启动时，熟成间室13内的气流可以在内循环风道133和熟成腔135之间循环流动。
具体地，冷藏间室11、熟成间室13和冷冻间室12可以从上往下依次布置，即熟成间室13处于冷藏间室11和冷冻间室12之间，便于熟成间室13与冷藏间室11和冷冻间室12连通。
在一些实施例中，冷藏冷冻装置1还包括冷藏引风风机21和冷冻引风风机22。冷藏引风风机21配置成受控地将冷藏间室11内的气流通过熟成送风口131引入熟成间室13。冷冻引风风机22配置成受控地将冷冻间室12内的气流通过熟成送风口131引入熟成间室13。由此，可以提高冷藏间室11内的气流流入熟成间室13的流速以及冷冻间室12内的气流流入熟成间室13的流速，从而提高熟成间室13内的温湿度调节效率。
在一些实施例中，熟成送风口131分别通过冷藏送风风道31和冷冻送风风道32与冷藏间室11和冷冻间室12连通，且经由冷藏送风风道31送入熟成间室13的气流量和经冷冻送风风道32送入熟成间室13的气流量均可调。也就是说，送入熟成间室13内的来自冷藏间室11的气流量可调，送入熟成间室13的来自冷冻间室12的气流量也可调，由此，可通过对来自冷藏间室11的气流量和来自冷冻间室12的气流量的调节进一步提高熟成间室13内温湿度的控制精确度。
在一些实施例中，冷藏送风风道31的其中一端通过冷藏引风口111与冷藏间室11连通，冷冻送风风道32的其中一端通过冷冻引风口121与冷冻间室12连通，冷藏送风风道31的另一端和冷冻送风风道32的另一端汇聚形成交汇处33，并与熟成送风口131连通。也就是说，冷藏间室11内的气流可通过冷藏引风口111流入冷藏送风风道31，最后通过熟成送风口131送入熟成间室13。冷冻间室12内的气流可通过冷冻引风口121流入冷冻送风风道32，最后通过熟成送风口131送入熟成间室13。
进一步地，交汇处33设有风量调节装置40，风量调节装置40配置成受控地调节冷藏送风风道31和冷冻送风风道32的气流出口大小，从而调节经由冷藏送风风道31和冷冻送风风道32流出的气流量大小。可见，本发明将冷藏送风风道31和冷冻送风风道32的另一端汇聚在一起并形成交汇处33，可以只在交汇处33设置一个风量调节装置40即可同时调节冷藏送风风道31和冷冻送风风道32的气流出口大小，减少了风量调节装置40的数量，简化了冷藏冷冻装置1的结构，降低了其成本。
具体地，风量调节装置40可以为电控风门，该电控风门通过改变对冷藏送风风道31和冷冻送风风道32的气流出口的遮蔽面积调节冷藏送风风道31和冷冻送风风道32的气流量。冷藏送风风道31和冷冻送风风道32的气流量可以从零到百分之百之间进行调节，也可以为零或百分之百，即全部遮蔽或全部打开。
在另一些实施例中，风量调节装置40还可以为风路稍复杂的送风调节组件，只要能够实现对藏送风风道31和冷冻送风风道32的气流量调节即可。
进一步地，冷藏引风口111和冷冻引风口121处可分别设有冷藏引风风机21和冷冻引风风机22，以便于促使气流快速地定向流动。
在一些实施例中，箱体10内还限定有冷藏蒸发器室14和冷冻蒸发器室15，用于为冷藏间室11提供冷量的冷藏蒸发器51设置于冷藏蒸发器室14内，用于为冷冻间室12提供冷量的冷冻蒸发器52设置于冷冻蒸发器室15内。熟成出风口132通过冷藏回风风道34与冷藏间室11或冷藏蒸发器室14连通，以允许从熟成出风口132流出的气流返回冷藏间室11或冷藏蒸发器室14；熟成出风口132通过冷冻回风风道35与冷冻间室12或冷冻蒸发器室15连通，以允许从熟成出风口132流出的气流返回冷冻间室12或冷冻蒸发器室15。
也就是说，当冷藏间室11向熟成间室13送风时，气流可以在冷藏间室11、熟成间室13和冷藏蒸发器室14之间循环流动，也可以在冷藏间室11和熟成间室13之间循环流动。当冷冻间室12向熟成间室13送风时，气流可以在冷冻间室12、熟成间室13和冷冻蒸发器室15之间循环流动，也可以在冷冻间室12和熟成间室13之间循环流动。
可以理解的是，熟成出风口132与冷藏间室11连通所对应的冷藏回风风道34的延伸路径与熟成出风口132与冷藏蒸发器室14连通所对应的冷藏回风风道34的延伸路径可以有所不同。熟成出风口132与冷冻间室12连通所对应的冷藏回风风道34的延伸路径与熟成出风口132与冷冻蒸发器室15连通所对应的冷冻回风风道35的延伸路径可以有所不同。
在另一些实施例中，冷藏间室11、熟成间室13和冷冻间室12从上往下依次布置。当熟成出风口132与冷藏间室11连通时，冷藏回风风道34可以为开设在用于分隔冷藏间室11和熟成间室13的分隔板上的回风口；当熟成出风口132与冷冻间室12连通时，冷冻回风风道35可以为开设在用于分隔冷冻间室12和熟成间室13的分隔板上的回风口。
图8是根据本发明另一个实施例的冷藏冷冻装置的示意性剖视图的部分放大图，图9是根据本发明另一个实施例的熟成间室的气流内循环时的气流流动示意图，图10是根据本发明另一个实施例的仅向熟成间室内引入冷藏间室气流的气流流动示意图。在另一些 实施例中，熟成出风口132通过冷藏回风风道34与冷藏间室11连通，冷藏回风风道34的气流出口处设有风路选择装置60。风路选择装置60配置成受控地将冷藏回风风道34的气流出口与冷藏间室11连通以允许冷藏回风风道34内的气流返回冷藏间室11、或将冷藏回风风道34的气流出口与冷藏引风口111连通并阻断冷藏引风口111与冷藏间室11的连通以允许冷藏回风风道34内的气流直接通过冷藏引风口111流向冷藏送风风道31。
具体地，参见图10，当需要向熟成间室13内引入冷藏间室11内的气流时，风路选择装置60受控地将冷藏回风风道34的气流出口与冷藏间室11连通，此时，经冷藏引风口111进入冷藏送风风道31的气流为冷藏间室11内的气流，从冷藏回风风道34流出的气流返回冷藏间室11中，从而实现气流在冷藏间室11和熟成间室13之间循环流动。当不需要向熟成间室13内引入任何一个间室的气流时，参见图9，风路选择装置60受控地将冷藏回风风道34的气流出口与冷藏引风口111连通并阻断冷藏引风口111与冷藏间室11的连通，此时，经冷藏引风口111进入冷藏送风风道31的气流为冷藏回风风道34中的来自熟成间室13内的气流，也就是说，气流在熟成间室13、冷藏回风风道34和冷藏送风风道31之间循环流动，实现的是熟成间室13的内循环。
此时，内循环风机23可以设置在冷藏回风风道34或冷藏送风风道31中，或者设置在冷藏引风口111处。可以理解的是，在这种实施例中，内循环风机23与冷藏送风风机21所驱动的气流流动路径基本一致，因此，可以只保留一个风机，当风路选择装置60所处的状态不同时，该风机所起到的作用也不同。由此，减少了风机的数量，有效地利用了冷藏送风风道31和冷藏回风风道34实现熟成间室13的内循环，不用额外设置内循环风道，在很大程度上简化了冷藏冷冻装置1的结构。
在一些实施例中，熟成间室13内设有熟成罩壳134，熟成罩壳134内限定有用于容装待熟成物的熟成腔135。熟成罩壳134的顶板与熟成间室13的顶壁间隔设置，以形成气流流道136，气流流道136与熟成送风口131连通。熟成罩壳134的顶板上开设有用于供气流流道136内的气流流入熟成腔135的多个吹风口1341，熟成出风口132开设在熟成罩壳134的其中一个侧板1342上，以便于从熟成腔135的顶部向其内送风、从熟成腔135的侧部向外出风，尽可能地延长了气流在熟成腔135内的流动路径，确保待熟成物的各个部分都能够得到吹风。
具体地，气流流道136可以沿熟成间室13的进深方向(即前后方向)延伸。冷藏送风风道31和冷冻送风风道32可处于熟成间室13内、并处于熟成罩壳134外。侧板1342优选为熟成罩壳134的后向侧板，且熟成送风口131处于熟成间室13的后侧，以便于在箱体10的后侧布置冷藏送风风道31、冷冻送风风道32、冷藏回风风道34和冷冻回风风道35。
在一些实施例中，多个吹风口1341的大小均相同，且多个吹风口1341在气流流道136内的气流流动方向上的排布密度递增、在与该气流流动方向垂直的横向上的排布密度均匀。多个吹风口1341在气流流动方向上的排布密度递增，可通过吹风口1341的排布密度递增的方式弥补气流流速在气流流动方向上递减的缺陷，提高了熟成腔135在平行于气流流动方向的纵向上各处的送风均匀性。多个吹风口1341在垂直于气流流动方向的 横向上的排布密度均匀，由此，提高了熟成腔135在横向上各处的送风均匀性。可见，本发明通过对吹风口1341的位置、数量和密度的设置实现风幕式送风，提高了熟成腔135内各处的送风均匀性，确保了待熟成物具有均匀的熟成效果。
在一些实施例中，熟成腔135内设有用于搁置待熟成物的置物网架，置物网架具有多个镂空的网孔，且置物网架与熟成腔135的底壁间隔设置，便于气流同时对搁置在置物网架上的待熟成物的上下表面进行吹送，从而确保了待熟成物的上表面和下表面均能够尽快地达到风干效果。
本发明还提供一种上述任一实施例所描述的冷藏冷冻装置1的控制方法，图11是根据本发明一个实施例的冷藏冷冻装置的控制方法的示意性流程图，参见图11，本发明的控制方法包括：
步骤S10，获取熟成间室13内的环境湿度和环境温度；以及
步骤S20，根据熟成间室13内的环境湿度和环境温度控制熟成间室13与冷藏间室11之间以及熟成间室13与冷冻间室12之间的导通状态、以及内循环风机23的启停。
由此，确保了熟成间室13始终具有合适的温度、湿度和持续的送风，确保了待熟成物的熟成环境，提高了待熟成物的熟成效率和熟成效果。
在一些实施例中，上述步骤S20具体可包括：
判断熟成间室13内的环境湿度与预设湿度阈值之间、以及熟成间室13内的环境温度与预设温度阈值之间的大小。具体地，预设湿度阈值和预设温度阈值可以为能够确保待熟成物达到熟成效果的湿度和温度，对于不同类型的待熟成物，预设湿度阈值和预设温度阈值的取值可能有所不同。
若熟成间室13内的环境湿度大于预设湿度阈值、且熟成间室13内的环境温度大于预设温度阈值，则控制熟成间室13只与冷冻间室12连通。也就是说，当熟成间室13内的环境温度和环境湿度都比较高时，可通过向熟成间室13内引入冷冻间室12内的气流，从而快速地降低熟成间室13内的环境温度和环境湿度。其中，控制熟成间室13只与冷冻间室12连通的方式可以为只启动冷冻引风风机22。
若熟成间室13内的环境湿度大于预设湿度阈值、且熟成间室13内的环境温度小于预设温度阈值，则控制熟成间室13只与冷藏间室11连通。也就是说，当熟成间室13内的环境湿度较高、环境温度较低时，可通过向熟成间室13内引入湿度较低、温度不是很低的冷藏间室11的气流，从而在降低熟成间室13湿度的基础上不至于使熟成间室13内的环境温度更低。其中，控制熟成间室13只与冷藏间室11连通的方式可以为只启动冷藏引风风机21。对于包含风路选择装置60的实施例来说，还需要将风路选择装置60设置成使冷藏回风风道34的气流出口与冷藏间室11连通的状态。
若熟成间室13内的环境湿度小于预设湿度阈值、且熟成间室13内的环境温度大于预设温度阈值，则同时执行或交替执行如下两种操作：控制熟成间室13只与冷冻间室12连通；启动内循环风机23以促使熟成间室13内的气流循环流动。也就是说，当熟成间室13内的环境湿度较低、环境温度较高时，一方面，可通过向熟成间室13内引入少量的冷冻间室12的气流以快速地降低熟成间室13内的温度，避免待熟成物因温度过高而 腐败变质，也避免引入冷冻间室12的气流过多导致熟成间室13湿度进一步降低；另一方面，可以通过熟成间室13内的气流循环促使待熟成物自身挥发的水分均匀地遍布整个熟成间室13，从而通过待熟成物自身挥发的水分提高熟成间室13内的环境湿度。其中，控制熟成间室13只与冷冻间室12连通的方式可以为只启动冷冻引风风机22。对于包含风路选择装置60的实施例来说，在需要促使熟成间室13内的气流循环流动时，还需要将风路选择装置60设置成使冷藏回风风道34的气流出口与冷藏引风口111连通且阻断冷藏间室11与冷藏引风口111连通的状态。
若熟成间室13内的环境湿度小于预设湿度阈值、且熟成间室13内的环境温度小于预设温度阈值，则阻断熟成间室13与冷藏间室11之间以及熟成间室13与冷冻间室12之间的连通，并启动内循环风机23，以促使熟成间室13内的气流循环流动。也就是说，当熟成间室13内的环境温度和环境湿度都较低时，不需要再向其内引入冷却气流，只需要启动熟成间室13的气流内循环，通过待熟成物自身挥发的水分提高熟成间室13内的环境湿度即可。对于包含风路选择装置60的实施例来说，还需要将风路选择装置60设置成使冷藏回风风道34的气流出口与冷藏引风口111连通且阻断冷藏间室11与冷藏引风口111连通的状态。
在一些实施例中，熟成间室13内的环境湿度可以通过设置在熟成腔135内的湿度传感器71获得。熟成间室13内的环境温度可以通过设置在熟成腔135内的温度传感器72获得。
