Description

冷藏冷冻装置及其控制方法 技术领域
本发明涉及冷藏冷冻技术，特别是涉及一种冷藏冷冻装置及其控制方法。
背景技术
熟成是将排酸后的肉类放置在一定温度、湿度、风速的熟成间室内，缓慢自然发酵，最终产生更深层次的风味，提升肉的嫩度、风味和多汁性等。现有的熟成装置一般是独立的，需要设计专门的控温装置和控湿装置，结构比较复杂。并且，熟成过程中对风速的要求一般为0.5-2.5m/s，如果风速过低会造成待熟成物表面水分蒸发较慢，湿度较高，易造成微生物的生长繁殖。若熟成过程中用于提供风速的风机出现异常，熟成室内风速很小或几乎没有风速，这种情况下极易造成待熟成物的腐败变质，导致熟成失败。
发明内容

减少所述送风风机送往所述储物间室的送风量、增大所述送风风机送往所述熟成室的送风量的步骤包括：
减小所述间室送风风门的开度、增大所述熟成送风风门的开度；
仅朝向所述熟成室送风的步骤包括：
关闭所述间室送风风门，打开所述熟成送风风门。
根据本发明的第二方面，本发明还提供一种冷藏冷冻装置，包括限定有储物间室的箱体、限定有熟成室以供待熟成物在其内熟成的熟成装置、用于提供冷却气流的蒸发器以及用于促使冷却气流流向所述储物间室和/或所述熟成室的送风风机；所述熟成装置内限定有熟成室和围设在所述熟成室外围的循环风道，且包括用于驱动气流在所述熟成室和所述循环风道之间循环流动的循环风机；所述冷藏冷冻装置还包括：

所述冷藏冷冻装置还包括用于受控地导通或阻断所述间室送风风道的间室送风风门和用于受控地导通或阻断所述熟成送风风道的熟成送风风门。
可选地，所述熟成装置包括：
内壳体，其内部限定有所述熟成室；

本发明的冷藏冷冻装置集成有熟成装置，其不但具有传统的低温环境下的储物保鲜功能，而且还具有熟成功能，丰富了冷藏冷冻装置的功能。并且，本发明的控制方法在用于驱动气流循环流经熟成室的循环风机出现异常时，一方面发出提示信息以提示用户循环风机出现故障，便于用户及时检修；另一方面还自动地根据储物间室的制冷状态合理地调节储物间室的送风量，使得送风风机驱动的冷却气流更多地或全部地流向熟成室，从而利用冷却气流 吹送熟成室内的待熟成物，避免了因循环风机出现故障导致待熟成物表面风速过小而容易腐败变质的问题。
进一步地，申请人认识到，由于冷却气流的温度较低，若利用冷却气流吹送待熟成物，不可避免地会引起熟成室内的温度降低，当熟成室内的温度降低至其设定目标温度后，会触发冷藏冷冻装置停止向熟成室内提供冷量，即停止向熟成室内输送冷却气流。然而，待熟成物又具有吹送气流的需求，这一需求与熟成室内的温度控制相矛盾。为了解决上述矛盾，本发明在向熟成室内输送冷却气流后还进一步下调熟成室的设定目标温度，在确保熟成室内的温度能够满足熟成最低要求的基础上，延迟了停止向熟成室内提供冷量的时间点，延长了向熟成室内输送冷却气流的时间，在有效地防止待熟成物因表面风速过小而腐败变质的前提下，为用户检修循环风机争取了较长时间。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
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风道盖板及其相关结构的示意性后视图；
图3是根据本发明一个实施例的熟成装置的示意性剖视图；
图4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；
图5是根据本发明另一个实施例的冷藏冷冻装置的控制方法的示意性流程图；
图6是根据本发明一个实施例的冷藏冷冻装置的示意性结构框图；
图7是根据本发明一个实施例的熟成装置的示意性结构分解图。
具体实施方式
本发明首先提供一种冷藏冷冻装置的控制方法，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风道盖板及其相关结构的示意性后视图，图3是根据本发明一个实施例的熟成装置的示意性剖视图。参见图1至图3，本发明的冷藏冷冻装置1包括限定有储物间室11的箱体10、用于供待熟成物在其内熟成的熟成装置20、用于提供冷却气流的蒸发器31以及用于促使冷却气流流向储物间室11和/或熟成室221的送风风机32。熟成装置20内限定有熟成室221和围设在熟成室221外围的循环风道24，且包括用于驱动气流在熟成室221和循环风道24之间循环流动的循环风机23。
进一步地，熟成装置20可设置在储物间室11中，储物间室11可以为具有冷藏储物环境的冷藏间室。储物间室11的后方可设有风道盖板70，蒸发器31可设置在位于风道盖板70后方的蒸发器室内。
具体地，当熟成室221内的温度高于其设定目标温度时，送风风机32可促使冷却气流进入熟成室221，从而降低熟成室221内的温度。当熟成室221内的温度低于其设定目标温度时，送风风机32可停止向熟成室221内输送冷却气流。在熟成过程中，循环风机23持续运行，当循环风机23运行正常(即没出现故障)时，在循环风机23的驱动作用下，气流在熟成室221和循环风道24之间循环流动，从而持续地吹送容置在熟成室221内的待熟成物。
本发明的控制方法是在循环风机23出现异常(即出现故障)的情况下实现气流持续地吹送熟成室221内的待熟成物。
图4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。本发明的控制方法包括：
步骤S10，在循环风机23出现异常时，发出用于表示循环风机23故障的提示信息；
步骤S20，判断储物间室11是否处于制冷状态；若是，则转步骤S30，若否，则转步骤S40；
步骤S30，减少送风风机32送往储物间室11的送风量、增大送风风机32送往熟成室221的送风量；
步骤S40，强制启动制冷，并仅朝向熟成室221送风。
可以理解的是，当储物间室11处于制冷状态时，制冷剂循环流经冷藏冷冻装置1的制冷系统，流经蒸发器31的制冷剂与流经蒸发器31的气流进 行热交换，从而形成冷却气流。送风风机32运行，促使冷却气流流向储物间室11。相应地，当储物装置11处于非制冷状态时，制冷系统中没有制冷剂流过，送风风机32处于停机状态，不会朝向储物间室11送风。此时强制启动制冷意指使得制冷剂在制冷系统中循环流动，并启动送风风机32。
当用于驱动气流循环流经熟成室221的循环风机23出现异常时，本发明一方面发出提示信息以提示用户循环风机23出现故障，便于用户及时检修；另一方面还自动地根据储物间室11的制冷状态合理地调节储物间室11的送风量，使得送风风机32驱动的冷却气流更多地或全部地流向熟成室221，从而利用冷却气流吹送熟成室221内的待熟成物，避免了因循环风机23出现故障导致待熟成物表面风速过小而容易腐败变质的问题。
申请人认识到，由于冷却气流的温度较低，若利用冷却气流吹送待熟成物，不可避免地会引起熟成室内的温度降低，当熟成室内的温度降低至其设定目标温度后，会触发冷藏冷冻装置停止向熟成室内提供冷量，即停止向熟成室内输送冷却气流。然而，待熟成物又具有吹送气流的需求，这一需求与熟成室内的温度控制相矛盾。
为此，在一些实施例中，参见图5所示的根据本发明另一个实施例的冷藏冷冻装置的控制方法的示意性流程图，在步骤S30或步骤S40之后，本发明的控制方法还包括：
步骤S50，下调熟成室221的设定目标温度；其中
该设定目标温度为停止向熟成室221提供冷量的温度，俗称停机点温度。
也就是说，为了解决上述矛盾，本发明在向熟成室221内输送冷却气流后还进一步下调熟成室221的设定目标温度，在确保熟成室221内的温度能够满足熟成最低要求的基础上，延迟了停止向熟成室221内提供冷量的时间点，延长了向熟成室221内输送冷却气流的时间，在有效地防止待熟成物因表面风速过小而腐败变质的前提下，为用户检修循环风机23争取了较长的时间。
在一些实施例中，本发明的控制方法还包括：
当熟成室221内的温度低于下调后的设定目标温度后，停止向熟成室221内送风，以避免熟成室221内的温度过低而影响熟成效果。
进一步地，本发明的控制方法还包括：
当熟成室221内的温度高于下调后的设定目标温度后，恢复向熟成室 221内送风，一方面可以降低熟成室221内的温度，使其更加有利于待熟成物熟成，另一方面，还可以继续对待熟成物吹送冷却气流，避免熟成室221内长时间没有气流吹送导致待熟成物腐败变质的问题。
在一些实施例中，箱体10内还限定有连通蒸发器31所在的蒸发器室12和熟成室221的熟成送风风道13。冷藏冷冻装置1还包括用于受控地导通或阻断熟成送风风道13的熟成送风风门41。具体地，熟成送风风门41可设置在熟成送风风道13内，也可以设置在熟成送风风门41的任一个端部。
进一步地，停止向熟成室221内送风的步骤可包括关闭熟成送风风门41，控制简便，结构简单。
进一步地，恢复向熟成室221内送风的步骤可包括打开熟成送风风门41，控制简便，结构简单。
在一些实施例中，箱体10内还限定有连通蒸发器31所在的蒸发器室12和储物间室11的间室送风风道14以及连通蒸发器室12和熟成室221的熟成送风风道13。具体地，间室送风风道14和熟成送风风道13均可形成在位于储物间室11后方的风道盖板70上。冷藏冷冻装置1还包括用于受控地导通或阻断间室送风风道14的间室送风风门42和用于受控地导通或阻断熟成送风风道13的熟成送风风门42。具体地，熟成送风风门41可设置在熟成送风风道13内，也可以设置在熟成送风风门41的任一个端部。间室送风风门42可设置在间室送风风道14中，也可以设置在间室送风风道14的任一个端部。
进一步地，减少送风风机32送往储物间室11的送风量、增大送风风机32送往熟成室221的送风量的步骤具体可包括：
减小间室送风风门42的开度、增大熟成送风风门41的开度。
进一步地，仅朝向熟成室221送风的步骤包括：
关闭间室送风风门42，打开熟成送风风门41。
也就是说，储物间室11和熟成室221内的送风与否、以及送风量大小可通过间室送风风门42和熟成送风风门41这两个风门的开闭以及开度的控制来实现。可以理解的是，当间室送风风门42和熟成送风风门41的开度为零时，即间室送风风门42和熟成送风风门41处于关闭状态；当间室送风风门42和熟成送风风门41的开度为100％时，即间室送风风门42和熟成送风风门41处于完全打开状态。
本发明还提供一种冷藏冷冻装置，本发明的冷藏冷冻装置1包括限定有储物间室11的箱体10、用于供待熟成物在其内熟成的熟成装置20、用于提供冷却气流的蒸发器31以及用于促使冷却气流流向储物间室11和/或熟成室221的送风风机32。熟成装置20内限定有熟成室221和围设在熟成室221外围的循环风道24，且包括用于驱动气流在熟成室221和循环风道24之间循环流动的循环风机23。
特别地，参见图6所示的根据本发明一个实施例的冷藏冷冻装置的示意性结构框图，冷藏冷冻装置1还包括提示装置50和控制装置60。提示装置50配置成在循环风机23出现异常时发出用于表示循环风机23故障的提示信息。具体地，提示装置50包括但不限于蜂鸣器、喇叭等发声装置和LED灯等发光装置。控制装置60包括处理器61和存储器62，存储器62内存储有机器可执行程序63，并且机器可执行程序63被处理器61执行时用于实现上述任一实施例所描述的控制方法。
本发明的冷藏冷冻装置集成有熟成装置，其不但具有传统的低温环境下的储物保鲜功能，而且还具有熟成功能，丰富了冷藏冷冻装置的功能。并且，还能够根据储物间室11的制冷状态合理地调节储物间室11的送风量，使得送风风机32驱动的冷却气流更多地或全部地流向熟成室221，从而利用冷却气流吹送熟成室221内的待熟成物，避免了因循环风机23出现故障导致待熟成物表面风速过小而容易腐败变质的问题。
图7是根据本发明一个实施例的熟成装置的示意性结构分解图。在一些实施例中，熟成装置20还包括筒体20a，外壳体21、内壳体22和循环风机23等形成顶部敞开的抽屉20b，该抽屉20b可推拉地设置在筒体20a内，从而形成相对封闭的熟成室221。同时，还便于向熟成室221放入待熟成物或从熟成室221中取出待熟成物，提高了用户操作的简便性。
在一些实施例中，箱体10内还限定有连通蒸发器31所在的蒸发器室12和储物间室11的间室送风风道14以及连通蒸发器室12和熟成室221的熟成送风风道13。间室送风风道14和熟成送风风道13相互独立。一方面，熟成室221与储物间室11的送风互不影响；另一方面，经熟成送风风道13送出的全部气流均可以流向熟成室221，经间室送风风道14送出的全部气流均可以流向储物间室11，增大了熟成室221单独需要送风时的送风量以及储物间室11单独需要制冷时的送风量。
进一步地，冷藏冷冻装置1还包括用于受控地导通或阻断间室送风风道14的间室送风风门42和用于受控地导通或阻断熟成送风风道13的熟成送风风门41，以便于更加简便地调节储物间室11和熟成室221内的送风量。
在一些实施例中，熟成装置20包括外壳体21和内壳体22。熟成室221限定在内壳体22的内部。外壳体21设置在内壳体22的外部，且外壳体21的后壁、以及两个横向侧壁分别与内壳体22的后壁和两个横向侧壁间隔设置，以形成U型的循环风道24，循环风道24通过开设在内壳体22的两个横向侧壁上的多个送风口222与熟成室221连通。由此，送风风道24内的气流分别经开设在内壳体22的两个横向侧壁上的送风口222送往熟成室221。也就是说，气流从熟成室221的两个横向侧部同时流入熟成室221，提高了气流在熟成室221横向上的送风均匀性，从而提高了待熟成物的熟成效果。
进一步地，循环风机23设置在位于内壳体22后方的循环风道24中，且循环风机23的气流入口与开设在内壳体22后壁上的回风口223相连通，循环风机23的两个相对的气流出口分别与位于内壳体22横向两侧的循环风道24相连通。由此，可利用一个循环风机23向循环风道24的两个位于不同侧的区段同时送风，简化了熟成装置20的结构。具体地，循环风机23可以为单向进风、双向出风的离心风机。
在一些实施例中，熟成送风风道13的数量为两个。两个熟成送风风道13的其中一端均与蒸发器室12直接连通，两个熟成送风风道13的另一端分别连通至位于内壳体22横向两侧的循环风道24，以在循环风机23出现故障时，同时向送风风道24的两个不同的区段输送冷却气流，从而使得冷却气流分别经开设在内壳体22的两个横向侧壁上的送风口222送往熟成室221，提高了冷却气流在熟成室221横向上的送风均匀性，从而提高了待熟成物的熟成效果。
具体地，外壳体21的后壁211上可开设有分别位于循环风机23两侧的两个引风口212，两个熟成送风风道13的另一端分别与两个引风口212连通。
进一步地，引风口212的开设方向可设置成使得经进风口212引入送风风道24内的气流具有朝向背离循环风机23的方向流动的趋势，以在送风风道24内获得较大的流动速度，确保冷却气流吹向熟成室221内时仍然具有一定的速度大小。
多个送风口222在内壳体22的横向侧壁上以上疏下密的方式排布。也就是说，处于上部的送风口222的排布较为稀疏，处于下部的送风口222的排布较为密集，使得送风风道24内更多的气流流入熟成室221的下部，吹向待熟成物的底部，抑制了微生物的生长繁殖，从而避免了待熟成物因底部湿度较大而容易腐败变质的问题。
具体地，多个送风口222在内壳体22的每个横向侧壁上可排布成上部风口和下部风口两个区域，且上部风口的总面积与下部风口的总面积之间的比值优选在1:2～1:3之间，合理地分配了流向熟成室221上部区域和下部区域的气流量，一方面，可以确保熟成室221下部风速较大以加快待熟成物底部水分的蒸发，另一方面，还可以保证待熟成物其他区域均能够吹送到气流，从而达到较好的熟成效果。
具体地，多个送风口222可包括竖直延伸的多个竖向送风口和水平延伸的多个横向送风口。也就是说，竖向送风口和横向送风口均为条形风口，条形风口具有较大的过流面积，减小了气流流入熟成室221内的气流阻力，确保了气流吹向待熟成物的速度。并且，还可以通过不同方向延伸的竖向送风口和横向送风口的分布实现整个熟成室221在不同方向上的均匀送风或针对性地送风。
在一些实施例中，内壳体22内设有用于搁置待熟成物的置物网架25，置物网架25与内壳体22的底板间隔设置，以在置物网架25的下方留有气流流动空间，便于气流吹向搁置在置物网架25上的待熟成物的下表面，从而确保了待熟成物的下表面均能够尽快地达到风干效果。
具体地，置物网架25具有多个镂空的网孔，镂空设置的置物网架25还减少了待熟成物与置物网架25之间的接触面积，避免了待熟成物的部分表面因接触不到气流而腐败变质。
在一些实施例中，送风风道24包括位于内壳体22后方的第一送风区段241和分别形成在内壳体22横向两侧的第二送风区段242和第三送风区段243。第二送风区段242和第三送风区段243均沿其内的气流流动方向渐缩。具体地，第二送风区段242和第三送风区段243内的气流流动方向均为从后往前，第二送风区段242和第三送风区段243的横截面面积从后往前逐渐减小，以利用过流面积渐缩的方式避免第二送风区段242和第三送风区段243内的气流流速在气流流动方向上逐渐减小的现象，提高了熟成室221的纵向 上各处的送风均匀性，确保了待熟成物在纵向上的表面各区域均具有均匀的气流吹送效果。
申请人认识到，气流刚流入第二送风区段242和第三送风区段243时的速度较快，因此，与第二送风区段242和第三送风区段243的上游侧连通的送风口的进风量很小，会导致熟成室221后部区域的吹风量小。
为此，在一些实施例中，第二送风区段242和第三送风区段243内的上游设有邻接在部分送风口外侧的导风板26。也就是说，导风板26设置在送风风道24中，其可以堵截送风风道24中流动的部分气流，并将该部分气流引导至相应的送风口处，以确保处于上游的送风口也具有足够的进风量，进一步提高了熟成室221内在前后方向上的送风均匀性，提高了熟成效果。
