Description

冰箱冷藏室的分区制冷控制方法和分区制冷控制装置 技术领域
本发明涉及冰箱控制，特别是涉及一种冰箱冷藏室的分区制冷控制方法和分区制冷控制装置。
背景技术
现有冰箱通常利用布置于冷藏室内部的温度传感器感测其布置位置周围的温度，将该温度作为制冷控制的依据。
然而，使用这种控制方式进行冰箱控制时，在温度传感器测量的温度高于预设值时，冰箱冷藏室启动制冷。在冷藏室被搁物隔板分隔为多个相对独立的储物空间的情况下，刚放入物品的储物空间内温度可能高于其他储物空间，使用现有的冰箱温度控制方法，需要对整个冷藏室整体进行制冷，造成了电能浪费，在冷藏室的容积较大的情况尤其明显。
另外在冰箱冷藏室的实际使用过程中，使用者会经常对所存物品进行存取，刚放入的物品一般温度较高，物品的温度通过热辐射的方式传导至冷藏室整个需要一定的时间，在物品温度传导至冷藏室环境后，温度传感器感测的温度才会上升，启动压缩机等冷源装置对冷藏间室进行制冷。在此过程中，物品的温度有可能传导至与其接触的其他物品上，导致冰箱内已存的食物温度发生变化，造成营养流失，储藏效果下降。

具体实施方式
图1是根据本发明一个实施例的冰箱冷藏室的分区制冷控制装置适用冰箱的示意性结构图，为了示出冰箱内部结构，未示出门体。该冰箱一般性地可以包括：箱体110、搁物架组件120、红外传感装置130。
箱体110包括顶壁、底壁、后壁以及左右两个侧壁围成，箱体110前方设置门体(图中未示出)，门体可以采用枢轴结构连接于侧壁上。箱体110内部限定有冷藏室。
图2是根据本发明一个实施例的冰箱冷藏室的分区制冷控制装置一种适用冰箱中冷藏室内部部 件的示意性结构图，搁物架组件120将冷藏室分隔为多个储物空间140。其中一种优选结构为：搁物架组件120包括至少一个水平设置的隔板，以将冷藏室沿竖直方向分隔为多个储物空间140。在图2中，搁物架组件120包括第一隔板121、第二隔板122、第三隔板123，其中第一隔板121上方形成第一储物空间、第一隔板121与第二隔板122之间形成第二储物空间、第二隔板122与第三隔板123之间形成第三储物空间。在本发明的另一些实施例中，搁物架组件120中的隔板数量以及储物空间140的数量可以根据冰箱的容积以及使用要求预先进行配置。
在图2所示的实施例中，红外传感装置130为多个，每个红外传感装置130设置在一个储物空间140的箱体110内壁上，并配置成感测储物空间140中放置的物品150释放的红外辐射能量，以确定物品150的表面温度。在图2所示的实施例中，在第一储物空间中设置有第一红外传感装置，在第二储物空间中设置有第二红外传感装置，在第三储物空间中设置有第三红外传感装置，红外传感装置的数量依据储物空间140的数量进行设定。
图3是根据本发明一个实施例的冰箱冷藏室的分区制冷控制装置另一适用冰箱中冷藏室内部部件的示意性结构图，在该种冰箱中，为了节省红外传感装置130的硬件成本，使用螺旋传动组件300带动一个红外传感装置130感测多个储物空间的物品温度。
螺旋传动组件300竖直设置于冷藏室内部，包括螺杆310、螺母320、以及限位件。螺杆310竖直设置并贯穿多个储物空间140，螺母320通过螺纹与螺杆310啮合，并利用限位件用于限定螺母320相对于冷藏室的旋转角度，以使螺杆310以其轴向为中心转动时带动螺母320竖直移动。其中螺杆310可以被传动电机311的驱动，以螺杆310轴向为中心旋转，由于限位件限定了螺母320的角度，使得螺母320在螺杆310旋转过程中上下移动。在本实施例的冰箱中，螺杆310和螺母320可以采用滑动螺旋传动也可以选用滚动螺旋传动，将回转运动变为直线运动，带动螺母320实现竖直方向的上下移动。
红外传感装置130，固定设置于螺母320上，并朝向冷藏室设置，配置成感测多个储物空间140中放置的物品150释放的红外辐射能量，以确定物品150的表面温度。以上螺旋传动组件300、红外传感装置130可以设置于箱体110的侧壁或者背板上，一种优选的实施例为设置于背板上。
螺旋传动组件300在每个储物空间140内的预定高度处预设有感测位置，以供红外传感装置130移动至感测位置处后，对储物空间进行温度感测。该感测位置可以根据冰箱内部空间预先设置，通过对传动电机311的控制以及卡位机构在每个储物空间的预定高度处，驱动螺杆310停止旋转，直至红外传感装置130完成对该储物空间的温度感测后，带动红外传感装置130向下或向上运动至相邻储物空间的感测位置处。
图4是根据本发明一个实施例的冰箱冷藏室的分区制冷控制装置另一适用冰箱中红外传感装置的传动机构示意性结构图，图4示出的冰箱中，利用同步带传动组件400来实现对红外传感装置130的移动。
同步带传动组件400，设置于冷藏室内，且其同步带422处于一竖直平面内，并且同步带422包括竖直设置的贯穿多个储物空间140的竖直区段。同步带传动是由一根内周表面设有等间距齿形的环行带及具有相应吻合的轮所组成。它综合了带传动、链传动和齿轮传动各自的优点。转动时，通过带齿与轮的齿槽相啮合来传递动力。
滑块420，固定设置于以上同步带422竖直区段上，以在同步带传动组件300的带动下竖直移动；红外传感装置130固定设置于滑块420上，并朝向冷藏室设置，配置成感测多个储物空间140中放置的物品150释放的红外辐射能量，以确定物品150的表面温度。
同步带传动组件400可以设置于箱体110的侧壁或者背板上，一种优选的实施例为设置于侧壁上。红外传感装置130通过由红外线透射材料制成的传感装置盖板来感测红外线。传感装置盖板朝向冷藏室的表面可以与侧壁的内表面平齐，以提高冰箱冷藏室美观程度以及储物空间140的整齐。
同步带传动组件400中的主动轮421设置于同步带传动组件400的底端，在传动电机425的带动下旋转，以带动同步带422；从动轮424，设置于同步带传动组件400的顶端，并且同步带422的内侧绕设于主动轮421和从动轮424的外缘，同步带422的齿与主动轮421和从动轮424的齿槽相啮合，以在主动轮421的带动下移动。主动轮421和从动轮424可以张紧同步带422，将回转运动转换成滑块420的直线运动。在一种可选实例中，主动轮421和从动轮424的轮径、齿距均相同，并且其中心 的连线为竖直。
另外，同步带传动组件400还可以设置有导向杆423，导向杆423平行于竖直区段设置；并且滑块420具有供导向杆323贯穿的通孔，以利用导向杆423限定红外传感装置130移动方向。导向杆423在每个冷藏室内的预定高度处预设有感测位置，以供红外传感装置130移动至感测位置处，对储物空间进行温度感测。
同步带传动组件400在每个储物空间140内的预定高度处预设有感测位置，以供红外传感装置130移动至感测位置处后，对储物空间140内的物品150进行温度感测。该感测位置可以根据冰箱内部空间预先设置，通过对传动电机425的控制以及卡位机构确定每个冷藏室的感测位置，在红外传感装置130移动至该感测位置后主动轮21停止旋转，直至红外传感装置130完成对该储物空间140的温度感测后，带动红外传感装置130向下或向上运动至相邻储物空间140的感测位置处。
图2至图4中示出的各种红外传感装置130均不发射红外线，而是被动接收所感测空间内物品150发射的红外线及背景红外线，直接感知冰箱内物品温度的变化区域及温度，转换为相应的电信号。相比于现有技术中的红外传感器，红外传感装置130可以对整个储物空间140的红外线进行检测，而不是仅仅探测热源点位置。而且红外传感装置130可以为具有矩形视野的红外接收器，该矩形视野可以配置成使红外接收器的红外接收范围在水平面上的投影覆盖隔板。从而使得红外传感装置130可以感测放置于隔板上的物品所释放的红外辐射能量。红外接收器可以通过设置红外导向部件限制出以上矩形视野，通过限制检测方位提高检测精度，以对储物空间进行精确探测。以上不同实例的区别仅在于红外传感装置130感测储物空间内物品温度的方式，包括采用多个红外传感装置130分别感测、使用螺杆传动或者同步带传动方式带动一个红外传感装置130进行储物空间内物品的温度感测。
另外本实施例的冰箱还可以设置有用于感测冷藏室内环境平均温度的冷藏环境温度传感装置(图中未示出)。该冰箱冷藏室的分区制冷控制装置可以使用热敏电阻等温度传感器实现。本实施例的冰箱可以根据红外传感装置130确定的物品温度以及冷藏室内部环境温度进行制冷控制。
本实施例冰箱冷藏室的分区制冷控制装置适用的冰箱可以为风冷冰箱，图5是根据本发明一个实施例的冰箱冷藏室的分区制冷控制装置适用冰箱的制冷系统的示意图，以及图6是根据本发明一个实施例的冰箱冷藏室的分区制冷控制装置适用冰箱的制冷系统中风道组件的示意图。该制冷系统包括：风道组件、压缩机、冷藏风门250、风机230等。该冰箱可利用蒸发器、压缩机、冷凝器、节流元件等部件经由冷媒配管构成制冷循环回路，在压缩机启动后，使蒸发器释放冷量。
蒸发器可设置在蒸发器室中。蒸发器冷却后的空气经风机230向贮藏室传送。例如冰箱的贮藏室的内部可分隔为变温室、冷藏室和冷冻室，其中贮藏室的最上层为冷藏室，冷藏室的下层为变温室、变温室的下层为冷冻室，蒸发器室可设置于冷冻室的后部。风机230设置于蒸发器室的上方的出口处。相应地，蒸发器冷却后的空气的供给风路包括与变温室相连的用于向变温室送风的变温供给风路、与冷冻室相连的用于向冷冻室送风的冷冻供给风路、以及与冷藏室相连的用于向冷藏室送风的冷藏供给风路。
优选地，以上压缩机以及风机230均可以设置多种运行模式，以满足冰箱不同工况下的制冷需求，例如可以设置正常制冷模式和快速制冷模式，其中在快速制冷模式下，冷藏风机230和压缩机均以高于正常制冷模式的转速运行，已释放更多的冷量，满足快速制冷的要求。
在本实施例中，风道组件为向冷藏室送风的风路系统，该风道组件包括：风道底板210、分路送风装置220、风机230。风道底板210上限定有分别通向多个储物空间140的多条风路214，各条风路214分别通向不同的储物空间140，例如在图1所示的实施例中，可以具有通向第一储物空间的第一供风口211、通向第二储物空间的第二供风口212、以及通向第三储物空间的第三供风口213。
分路送风装置220设置在冷藏供给风路中，冷藏供给风路形成在冷藏室的背面，分路送风装置220包括连接至冷源(例如蒸发器室)的进风口221以及分别与多条风路214连接的多个分配口222。分配口222分别连接至不同的风路214。该分路送风装置220可以受控地将风机230产生的来自于冷源的冷气经进风口221分配至不同的分配口222，从而经不同的风路214进入不同的储物空间140。
分路送风装置220可以将来自于冷源的制冷气流进行集中分配，而不是为不同的储物空间140单独设置不同的风道，提高了制冷效率。该分路送风装置220可以包括：壳体223、调节件224、盖板225。壳体223上形成有进风口221和分配口222，盖板225与壳体223组装，形成分路送风腔。调节件224布置于该分路送风腔内。调节件224具有至少一个遮挡部226，遮挡部226可动地设置于 壳体223内，配置成受控地对多个分配口222进行遮蔽，以调整多个分配口222的各自的出风面积。
风机230的送风会经过调节件224的分配供向不同的储物空间140，在图6所示的实施例中，分路送风装置220可以实现多达七种的送风状态，例如可以包括：供向第一供风口211的分配口222单独开，供向第二供风口212的分配口222单独开，供向第三供风口213的分配口222单独开，供向第一供风口211和第二供风口212的分配口222同时开，供向第一供风口211和第三供风口213的分配口222同时开，供向第二供风口212和第三供风口213的分配口222同时开、供向第一供风口211、供向第二供风口212和第三供风口213的分配口222同时开。在本实施例的冰箱由一个隔板隔出两个储物空间时，分路送风装置220可以设置有两个分配口，同时具备三种送风状态即可。在进行分路送风时，调节件224会旋转，会根据需求的风量大小来决定旋转的角度，并且遮挡部226之间形成的导引口会对准对应的分配口222。
壳体223在分路送风腔内设置有电机227、两个止挡柱228、定位座凹槽243，止挡柱228的作用是电机227在运转过程中，调节件224的运动更准确，且每次加电时或一段时间后，调节件224均运动至起始止挡柱228处，以其为起点转动至指定的转动位置。定位座凹槽243的作用是保证调节件224在每转动30度的角度位置时定位。调节件224上设置有盘簧片229(此盘簧片229也可以用扭簧来代替)、配重块241及定位销245。盘簧片229的一段固定于盖板225上，另一端随着调节件224的运转而预紧施加反向的力，始终向调节件224施加一定的偏置力，从而可抑制因直流步进电机227传动机构的齿隙导致的晃动问题。枢转部朝与调节件224的主体径向相反的方向延伸有配重部，在配重部的远端设置有配重块241，以消除偏置转矩。定位销245可上下移动(通过压簧)的固定在调节件224上。壳体223上设置有与之配合的定位座凹槽243。
需要注意的是，本实施例的冰箱以具有三个储物空间140的间室为例进行说明，在实际使用时，可以根据具体的使用要求，将红外传感装置130、风路214、分配口222、供风口的数量进行设置，以满足不同冰箱的要求。例如，根据以上介绍，容易得出具有两个储藏空间的冷藏室的送风系统。

冷源启动模块706，配置成第一判断模块704的判断结果为是，则驱动冷源以快速制冷模式运行并开启冷源至分路送风装置之间的冷藏风门，其中在快速制冷模式下，冷源中的冷藏风机和压缩机均以高于正常制冷模式的转速运行，从而在快速制冷模式下，冷源可以释放更多的冷量，相比于正常制冷模式，可更快地对高温物品进行制冷。

本发明实施例还提供了一种冰箱冷藏室的分区制冷控制方法，该冰箱冷藏室的分区制冷控制方法可以由以上任一实施例的冰箱冷藏室的分区制冷控制装置700来执行，以对冰箱冷藏室实现分区制冷。图8是根据本发明一个实施例的冰箱冷藏室的分区制冷控制方法的示意图。该冰箱冷藏室的分区制冷控制方法包括：
步骤S802，获取红外传感装置感测的多个储物空间内存储物品的温度；
步骤S804，判断存储物品的温度是否满足预设的快速制冷启动条件；
步骤S806，若是，则驱动冷源以快速制冷模式运行并开启冷源至分路送风装置之间的冷藏风门；
步骤S808，根据每个储物空间内存储物品的温度确定其制冷状态标识设置；
步骤S810，驱动分路送风装置运行至与多个储物空间的制冷状态标识对应的状态。
在实施例的冰箱冷藏室的分区制冷控制方法中，冷源中的冷藏风机和压缩机可以根据制冷工况，设置多个模式，例如在快速制冷模式下，冷源中的冷藏风机和压缩机均以高于正常制冷模式的转速运行。
步骤S804中的快速制冷启动条件可以为若多个储物空间内的至少一个存储物品的温度高于第一区域制冷开启温度阈值，相应地，步骤S804的一种可选流程为：将每个储物空间的存储物品的温度与每个储物空间各自预设的第一区域制冷开启温度阈值进行比较；若多个储物空间内的至少一个存储物品的温度高于第一区域制冷开启温度阈值，则确定满足预设的快速制冷启动条件。
如果步骤S804判断的出的结果为不满足快速制冷启动条件，则进入正常制冷模式的控制流程。
步骤S808的一种可选流程为：将每个储物空间内存储物品的温度与每个储物空间各自预设的第二区域制冷开启温度阈值进行比较；将物品温度大于区域制冷开启温度阈值的储物空间对应的制冷状态标识设置为启动。步骤S810中，可以驱动分路送风装置运行至向制冷状态标识为启动的储物空间提供制冷气流的状态。其中每个储物空间的第一区域制冷开启温度阈值大于其第二区域制冷开启温度阈值的数值为预设的第一裕量值。
在步骤S802之前，还可以预先获取冰箱上电启动信号；以及对冰箱的制冷系统进行初始化，制冷系统包括：压缩机、冷藏风门、风机、以及分路送风装置。初始化的步骤可以包括：关闭压缩机、风机、以及冷藏风门，并且驱动分路送风装置运行至初始位置。
在冰箱还包括冷冻室的情况下，在对冰箱的制冷系统进行初始化之后还包括：获取冷冻室的温度，并根据冷冻室的温度进行冷冻室的制冷判断，以调节压缩机、风机、以及冷藏风门的启停状态；以及在完成所述冷冻室的制冷判断后，启动获取红外传感装置感测的多个储物空间内存储物品的温度的步 骤。也就是，在初始化完成后，可以首先进行冷冻室的控制，然后进行冷藏室的控制。
本实施例的冰箱冷藏室的分区制冷控制方法，还可以利用冷藏室内环境平均温度作为关闭快速制冷的一个参数，其中冷藏室内还设置有用于感测冷藏室内环境平均温度的冷藏环境温度传感装置，并且在驱动分路送风装置运行至与多个储物空间的制冷状态标识对应的状态之后还包括：获取冷藏室内环境平均温度；判断冷藏室内环境平均温度以及每个储物空间内存储物品的温度是否满足预设的风门关闭条件；若是，驱动冷藏风门关闭，退出快速制冷模式并返回执行获取冷冻室的温度的步骤；若否，直接返回执行获取冷冻室的温度的步骤。
以上风门关闭条件包括：每个储物空间的内存储物品的温度均小于预设的区域制冷关闭温度阈值；或者在冷藏室内环境平均温度小于预设的冷藏室整体制冷关闭温度阈值的情况下，每个储物空间的内存储物品的温度均小于每个储物空间各自预设的第二区域制冷开启温度阈值；或者整体制冷关闭温度阈值减去冷藏室内环境平均温度的差值大于预设的第二裕量值。
本实施例的冰箱冷藏室的分区制冷控制方法可以对分隔有多个储物空间的冷藏室分别进行温度控制，以提高冷藏室内物品的储藏效果，以下以具有三个储物空间的冷藏室为例对以上分区制冷控制方法以及分区制冷控制装置进行介绍。
使用本实施例的冰箱冷藏室的分区制冷控制方法，预先可以根据冰箱冷藏室的特征以及存储物品的种类，预先确定以下参数：区域制冷开启温度阈值、区域制冷关闭温度阈值、整体制冷开启温度阈值、整体制冷关闭温度阈值、冷藏室设定温度以及冷冻室设定温度。表1示出了对具有三个储物空间的冷藏室的进行分区制冷设定的参数表：
表1
  传感器检测值 设定温度 开启温度阈值 关闭温度阈值
冷冻室 FT F-set F-on F-off
冷藏室环境 RT R-set R-on R-off
第一储物空间 IRT1 无 IR1-on IR1-off
第二储物空间 IRT2 无 IR2-on IR2-off
第三储物空间 IRT3 无 IR3-on IR3-off
由表1可以看出，对于冷冻室，传感器的检测温度值记为FT，冷冻室设定的温度为F-set；制冷开启温度阈值为F-on；制冷关闭温度阈值为F-off，其中F-set可由用户自行设定或者使用默认值，F-on和F-off可以根据F-set确定，一般满足关系F-on>F-set>F-off。
对于冷藏室，冷藏环境温度传感装置感测的冷藏室内环境平均温度记为RT，冷藏室设定的温度为R-set；整体制冷开启温度阈值为R-on；整体制冷关闭温度阈值为R-off，其中R-set可由用户自行设定或者使用默认值，R-on和R-off可以根据R-set确定，一般满足关系R-on>R-set>R-off。
对于冷藏室的第一储物空间，红外传感装置感测的第一储物空间内存储物品的最高温度记为IRT1，第一储物空间的区域制冷开启温度阈值为IR1-on；第一储物空间的区域制冷关闭温度阈值为IR1-off，其中IR1-on和IR1-off可以根据R-set以及第一储物空间内存储物品的种类确定，一般满足关系IR1-on>IR1-off。
对于冷藏室的第二储物空间，红外传感装置感测的第二储物空间内存储物品的最高温度记为IRT2，第二储物空间的区域制冷开启温度阈值为IR2-on；第二储物空间的区域制冷关闭温度阈值为IR2-off，其中IR2-on和IR2-off可以根据R-set以及第二储物空间内存储物品的种类确定，一般满足关系IR2-on>IR2-off。

对于以上冷藏室的不同储物空间，其中的区域制冷开启温度阈值IR1-on、IR2-on、IR3-on可以分别设置为相同也可以设置为不同，区域制冷开启温度阈值IR1-off、IR2-off、IR3-off也可以分别设置为相同也可以设置为不同。
另外针对快速制冷模式，还可以将R-off-k作为冷藏室整体快速制冷的关闭阈值，将IR1-on+M、IR2-on+M、IR3-on+M分别作为第一储物空间、第二储物空间、第三储物空间的第一区域制冷开启温度阈值、IR1、IR2、IR3作为第一储物空间、第二储物空间、第三储物空间的第二区域制冷开启温度阈值，其中k和M均为正数，分别作为第二裕量值和第一裕量值。
对于各个储物空间，还可以预先配置有制冷状态标识，用于指示是否需要对储物空间进行送风，例如第一储物空间的制冷标识记为gate1，第二储物空间的制冷标识记为gate2，第三储物空间的制冷标识记为gate3，以上gate1、gate2、gate3可以置位为启动和关闭，例如以“0”代表关闭，以“1”代表启动。
图9是根据本发明一个实施例的冰箱冷藏室的分区制冷控制方法的整体流程框图，冰箱的制冷控制器执行以下步骤：
步骤S902，获取冰箱上电启动信号；
步骤S904，冰箱的制冷系统初始化；
步骤S906，进行冷冻室制冷控制；
步骤S908，进行冷藏室分区制冷控制。
在完成步骤S908后，返回步骤S906，执行冷冻室制冷控制的判断流程。以下分别对以上步骤分别进行详细说明：
图10是根据本发明一个实施例的冰箱冷藏室的分区制冷控制方法中冰箱制冷系统初始化的流程图：
步骤S1002，关闭压缩机，使蒸发器停止释放冷量；
步骤S1004，关闭风机，停止向冷藏室供应气流；
步骤S1006，关闭冷藏风门，使冷藏室与蒸发器室隔绝；
步骤S1008，风路送风装置恢复至初始位置，例如使图6所示的风路送风装置的调节件运动至起始止挡柱处。
利用以上初始化，可以恢复默认状态，避免上次断电时部件运行不到位导致的控制逻辑混乱。
图11是根据本发明一个实施例的冰箱冷藏室的分区制冷控制方法中冷冻室的制冷控制的逻辑流程图。在冷冻室制冷控制启动后，可以执行以下步骤：
步骤S1102，判断FT是否大于F-on，若是执行步骤S1104，若否执行步骤S1108；
步骤S1104，判断压缩机是否处于启动状态，若是执行步骤S1110，若否执行步骤S1106；
步骤S1106，开启压缩机以及风机；
步骤S1108，判断压缩机是否处于启动状态，若是执行步骤S1110，若否执行步骤S1116；
步骤S1110，判断FT是否小于F-off，若是执行步骤S1112，若否执行步骤S1116；
步骤S1112，判断压缩机是否处于高转速运行状态，若是执行步骤S1116，若否执行步骤S1114；
步骤S1114，关闭压缩机以及风机；
步骤S1116，结束冷冻室制冷控制，准备进入冷藏室分区制冷。
图11所示的冷冻室制冷控制流程对压缩机以及风机的启动、停止、以及运行状态进行控制，在完成后，进入冷藏室分区制冷的控制。
图12是根据本发明一个实施例的冰箱冷藏室的分区制冷控制方法中快速制冷流程的逻辑流程图。该快速制冷流程适用于冰箱冷藏室内某一储物空间内放入高温食物，该高温食物的温度可能明显高于室温以及冷藏室的设定温度R-set。该快速制冷流程主要包括以下步骤：
步骤S1202，在结束冷冻室制冷控制后，启动冷藏室分区制冷。该步骤可以在图11所示的步骤S1116之后进行。
步骤S1204，驱动压缩机以及风机高速运行，并打开冷藏风门。在步骤S1204中，一种具体的实现流程为：首先判断是否出现IRT1>IR1-on+M、IRT2>IR2-on+M、IRT3>IR3-on+M中的任一种情况，其中M为预设常数，代表某一储物间室出现了温度高于第一储物间室开启制冷温度阈值M度的物品，即储存了高温食物，若判断为是则驱动风机以高转速运行，并使压缩机以高转速运行，若判断为否，判断压缩机是否处于高转速状态，若压缩机未处于高转速状态则执行步骤S1214，若压缩机处于高转速状态，则直接开启冷藏风门。在步骤S1204驱动风机、压缩机、以及冷藏风门的过程均包括状态判断过程，若判断出已处于需要的运行状态，则不重复进行控制。在驱动风机以及压缩机高速运行，并打开冷藏风门后，执行步骤S1206。
步骤S1206，使用多个储物空间设置的开启温度阈值以及关闭温度阈值确定制冷标识，以第一储物空间为例进行介绍，判断IRT1>IR1-on，若是将gate1设置为启动，若否判断gate1是否已为启动状态，若gate1为关闭状态，则对下一储物空间进行判断，若gate1为开启状态，判断IRT1<IR1-off，若是，将gate1设置为关闭并对下一储物空间进行判断，若否直接对下一储物空间进行判断，对应于其他储物空间如第二储物空间、第三储物空间，可以使用类似于第一储物空间的判断过程。图12中以三个储物空间的判断过程为例，在实际使用过程中，可以根据储物空间的数量进行增加和减少，并且各储物空间的判断过程的时序不受限定，可以逐一进行，也可以并行进行。
步骤S1208，根据步骤S1206中设定gate1、gate2、gate3的状态确定分路送风装置的运行状态，并驱动分路送风装置运行于该状态。图13至图20分别示出了分路送风装置的8种运行状态，其中图13为分路送风装置的初始状态，从该初始状态起始，控制调节件224顺时针转动预定角度，使定位销245伸入其中一个定位凹槽243中，利用遮挡部226，分别遮挡不同的分配口，以使制冷气流进入对应的储物间室。图14为分路送风装置的第一状态，第一分配口被遮蔽，第二分配口与第三分配口被打开；图15为分路送风装置的第二状态，第二分配口被遮蔽，第一分配口和第三分配口打开，图16为分路送风装置的第三状态，第二分配口打开，第一分配口和第三分配口被遮蔽；图17为分路送风装置的第四状态，第三分配口打开，第一分配口和第二分配口被遮蔽；图18为分路送风装置的第五状态，第一分配口打开，第二分配口和第三分配口被遮蔽；图19为分路送风装置的第六状态，第一分配口和第二分配口打开，第三分配口被遮蔽；图20为分路送风装置的第七状态，调节件224抵靠另一止挡柱、第一分配口、第二分配口、第三分配口全部打开。
表2示出了对具有三个储物空间的冷藏室的进行分区制冷设定的分路送风装置运行状态与各储物空间制冷标识的对应关系：
表2
Figure PCTCN2015090980-appb-000001
在表2中，on代表制冷标识对应启动，off代表制冷标识对应关闭。根据以上描述，本实施例还可以对具有两个储物空间以及多于三个的储物空间的情况进行分路送风装置的状态调整。
步骤S1210，根据制冷情况判断快速制冷是否完成，步骤S1210中，一种具体的实现流程为：首先当前储物空间的温度以同时满足IRT1<IR1-off、IRT2<IR2-off、IRT3<IR3-off的所有条件，若已满足，则关闭风门，退出高转速模式；若不满足，则判断是否RT<R-off，若RT大于或等于R-off则进入步骤S1212，若RT<R-off，则判断储物空间的温度以同时满足IRT1<IR1-on、IRT2<IR2-on、IRT3<IR3-on的所有条件，若已满足，同样关闭风门，退出高转速模式，若不满足，判断是否满足RT<(R-off-k)，也就是冷藏室环境平均温度RT已经低于R-off达到k度，其中k为预设常数，若满足RT<(R-off-k)，则关闭风门，退出高转速模式，若RT大于或等于R-off-k，则进入步骤S1212。在关闭风门，退出高转速模式之后，还可以判断冷冻室温度FT是否满足FT<F-off，若是，则关闭压缩机，进入步骤S1212，若否则直接进入步骤S1212。
步骤S1212，返回冷冻室制冷控制流程，例如返回执行步骤S1102。
步骤S1214，进入正常分区制冷控制流程。
图21是根据本发明一个实施例的冰箱冷藏室的分区制冷控制方法中正常制冷流程的逻辑流程图。该正常制冷流程适用于冰箱冷藏室平均温度升高，根据储物间室情况进行制冷的情况。该正常制冷流程主要包括以下步骤：
步骤S2102，启动冷藏室分区制冷。该步骤可以在图12所示的步骤S1214之后进行。
步骤S2104，驱动风机以及冷藏风门启动。步骤S2104一种具体的实现流程为：首先判断是否满足RT>R-on，若满足RT>R-on，则判断风机是否开启，若已开启，则将冷藏风门置于开启状态，然后直行步骤S2108，若风机未开启，则返回执行步骤S2112，若RT小于等于R-on，则判断冷藏风门是否为开启状态，若为开启状态则进入步骤S2104，若冷藏风门为关闭状态，则返回执行步骤S2112。
步骤S2106，判断冷藏室内环境平均温度和/或每个储物空间内存储物品的温度是否满足预设的冷藏室制冷停止条件；在满足冷藏室制冷停止条件时，关闭冷藏风门，然后直接返回执行步骤S2112，若不满足冷藏室制冷停止条件，执行步骤S2108。
步骤S2108，使用多个储物空间设置的开启温度阈值以及关闭温度阈值确定制冷标识，该步骤与图12中步骤S1206判断流程基本相同，对多个储藏空间分别进行判断，确定出各自的制冷标识。
步骤S2110，根据步骤S2108中设定gate1、gate2、gate3的状态确定分路送风装置的运行状态，并驱动分路送风装置运行于该状态。该步骤与图12中步骤S1208的流程基本相同，分路送风装置的状态与gate1、gate2、gate3的对应关系如表2所示。
步骤S2112，返回冷冻室制冷控制流程，例如返回执行步骤S1102。
以上步骤S2106所使用的冷藏室制冷停止条件有多种形式，图22是根据本发明一个实施例的冰箱冷藏室的分区制冷控制方法中判断冷藏室制冷停止的逻辑流程图，在步骤S2202启动冷藏室制冷停止判断流程后，依次执行以下步骤：
步骤S2204，判断是否同时满足IRT1<IR1-off、IRT2<IR2-off、IRT3<IR3-off的所有条件，若已满足，则关闭冷藏风门，执行图21中的步骤S2112；若不满足执行步骤S2206；
步骤S2206，判断是否满足RT<R-off，即冷藏室的环境平均温度低于预设关闭温度阈值，若RT<R-off执行步骤S2208的判断步骤，若RT大于等于R-off，直接执行图21中的步骤S2108；
步骤S2208，判断是否同时满足IRT1<IR1-on、IRT2<IR2-on、IRT3<IR3-on的所有条件，若是则关闭冷藏风门，执行图21中的步骤S2112；若不满足执行步骤S2210的判断步骤；
步骤S2210，判断判断是否满足RT<(R-off-k)，也就是冷藏室环境平均温度RT已经低于R-off达到k度，即R-off与RT相减的差值大于k其中k为预设常数，代表以上第二裕量值，若是则关闭冷藏风门，执行图21中的步骤S2112；直接执行图21中的步骤S2108。
图22示出了冷藏室制冷停止条件一种可选情况，在一些可选的简便判断流程中，也可以仅执行步骤S2204以及步骤S2206的步骤，在确定RT<R-off后关闭冷藏风门，执行图21中的步骤S2112，若RT大于等于R-off，直接执行图21中的步骤S2108，从而省略了步骤S2208以及步骤S2210。经过测试，该省略的制冷停止条件也可以达到控制的效果，但差于完整的图22的流程。
经过以上对一个具体实施例的冰箱冷藏室的分区制冷控制方法的说明，可以看出本实施例的分区制冷控制方法可以适应各种多冷藏储物空间的工况，有效实现了冷藏室分区制冷的要求。需要注意的是，本方法并不局限于对具有三个储藏空间的冷藏室进行控制，还可以通过简单的变形适用于具有两个储物空间以及多于三个的储物空间的冷藏室进行分路送风制冷控制。
