制冷室102包括冷藏室、冷冻室以及变温室等间室，每个间室有对应的制冷动力组件(例如，冷藏动力组件、冷冻动力组件及变温动力组件)来调节各间室内的温度。
制冷室箱门103通过门铰链104与箱体101连接，制冷室箱门103可以包括冷藏室箱门、冷冻室箱门以及变温室箱门三个，也可以是冷藏室箱门、冷冻室箱门以及变温室箱门三个一体成型，或者冷藏室箱门与变温室箱门一体成型。
在一些实施例中，门铰链104包括铰链座和铰链体，铰链座可以固定连接于箱体101上，铰链体一端通过铰链座的芯轴与箱体101相连，另一端与制冷室箱门103相连，使得制冷室箱门103能够自然平滑地旋转开启、关闭。图1所示的制冷室箱门103包括两扇由中间向两侧开启的箱门(从图1可观察到的表面为制冷室箱门103背离箱体101一侧的外表面)，所以箱体101两侧分别设置门铰链104。可以理解，在一些实施例中，制冷室箱门103可包括一扇整体的向一侧开启的箱门，此时在箱体101的一侧设置门铰链104即可。此外，当冰箱10具有多个制冷室箱门(例如，包括冷藏室箱门、冷冻室箱门和变温室箱门)时，在箱体101上对应每个制冷室箱门设置门铰链104即可。

气调保鲜装置100设置在制冷室102内，例如设置在冷藏室、冷冻室以及变温室等间室内。气调保鲜装置100包括容置盒110、抽屉120、气调膜130、气调动力组件140、气体浓度传感器106、人体检测传感器107以及控制部108。
请参考图2和图3，图2为本公开一些实施例的容置盒、气调膜和气调动力组件的装配示意图，图3为本公开一些实施例的抽屉的结构示意图。
如图2所示，容置盒110包括相连接的顶板111、两个侧板112、背板113、底板114以及框架115，其中，顶板111与底板114相对设置，两个侧板112分别位于顶板111与底板114的两侧，背板113与框架115相对设置，由此形成具有单侧开口的容置盒110，抽屉120则可通过开 口插入容置盒110内。
在一些实施例中，容置盒110内设置有导轨1141，抽屉120上设置有与导轨1141相配合的导向件122。例如，该导轨1141可沿容置盒110的深度方向设置，设置于抽屉120上的导向件122与导轨1141相配合，保证拉动抽屉120时的稳定性，便于开启和关闭抽屉120。
在一些实施例中，气调保鲜装置100还包括锁紧装置，该锁紧装置被配置为锁紧容置盒110和抽屉120，使得容置盒110与抽屉120之间形成密闭空间。在一些实施例中，导轨1141为自吸式多段导轨。在此基础上，锁紧装置可通过自吸式多段导轨来实现。设置在导向件122上的凹槽1221以及设置在自吸式多段导轨1141上与凹槽1221相对应的位置处的凸起互相配合，将抽屉120与自吸式多段导轨1141的第一段固定在一起。自吸式多段导轨1141的第一段指的是靠近容置盒110上的开口的一段。当抽屉120逐渐插入容置盒110内，自吸式多段导轨1141的自吸作用使得容置盒110与抽屉120锁紧以形成密闭空间，防止抽屉120松动，影响控氧效果。
在一些实施例中，框架115上环设有密封条，当抽屉120关闭时，由于锁紧装置的作用，使得抽屉120能够与密封条紧密接触，保证容置盒110内的气密性，防止外部空气进入容置盒110中。
在一些实施例中，气调保鲜装置100还包括开合检测机构，开合检测机构与控制部108相连接，被配置为检测抽屉120是否开启。当开合检测机构检测到抽屉120未开启时，控制部108则可以控制气调动力组件140开始工作，以降低容置盒110内的氧气含量。当开合检测机构检测到抽屉120开启时，控制部108则可以控制气调动力组件140停止工作，以降低气调动力组件140的功耗。在一些实施例中，该开合检测机构可以为光线传感器、红外传感器、摄像头或磁控开关1131中的任意一种，以实现对抽屉120的开合检测。
在一些实施例中，该开合检测机构包括设置于容置盒110上的磁控开关1131(例如干簧管等)以及设置于抽屉120上的磁性件121，磁控开关1131与控制部108相连接。由此，磁控开关1131与磁性件121相配合以实现检测抽屉120是否开启。示例地，磁控开关1131可设置在容置盒110的背板113上，抽屉120对应于该磁控开关1131的位置上设置有安装座，磁性件121可设置于该安装座上。
当开启抽屉120时，磁性件121远离磁控开关1131，以使得磁性件 121对磁控开关1131的磁吸力减小，由此磁控开关1131可以检测到抽屉120开启，控制部108根据磁控开关1131所传输的检测信号，控制气调动力组件140停止工作，以降低功耗；当抽屉120关闭时，磁性件121靠近磁控开关1131，使得磁性件121对磁控开关1131的磁吸力增大，磁控开关1131则检测到抽屉120关闭，控制部108根据磁控开关1131所传输的检测信号，控制气调动力组件140开始工作，以降低抽屉120内的氧气含量，延长抽屉120内储存物的保鲜时间。
气调膜130设置在容置盒110的外壁上，气调膜130的一侧朝向容置盒110内，另一侧朝向容置盒110外。其中，气调膜130在容置盒110的外壁上设置的位置可以根据实际情况选择，在此不做特殊限定。在一些实施例中，容置盒110的背板113上开设有通孔1132，气调膜130覆盖该通孔1132，使得容置盒110与抽屉120形成的空间内的空气可从该通孔1132通过气调膜130排出。
气调动力组件140与气调膜130朝向容置盒110外的一侧连接，气调动力组件140被配置为调节容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度。保鲜气体可以是防止容置盒110内储存的物品氧化的惰性气体，例如，保鲜气体为氮气。通过制冷室102内的制冷温度调节与容置盒110内的保鲜气体的共同作用实现冰箱10良好的保鲜功能。
在一些实施例中，气调动力组件140可以包括真空泵(未图示)和导流风机1401，气调动力组件140启动后可以驱使容置盒110与抽屉120所形成的空间内的空气通过气调膜130，空气会有选择性地通过气调膜130。氧气通过气调膜130的速率大于氮气通过气调膜130的速率。利用不同气体的通过速率不同，实现在气调膜130的两侧分别富集保鲜气体(例如氮气)和氧气，即从容置盒110抽出的气体中氧气含量较高，容置盒110内剩余气体中保鲜气体含量较高，由此调节容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度。
气体浓度传感器106设于容置盒110的内壁上，且位于容置盒110与抽屉120所形成的空间内，被配置为检测容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度。在一些实施例中，气体浓度传感器106可以是氮传感器，检测容置盒110与抽屉120所形成的空间内含有的氮气的浓度；也可以是氧传感器，检测容置盒110与抽屉120所形成的空间内含有的氧气的浓度，从而根据氧气的浓度得到保鲜气体的浓度。
需要说明的是，气体浓度传感器106设于容置盒110内壁上的位置可以根据需求设定，能够实现检测容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度即可。在一些实施例中，气体浓度传感器106设于容置盒110的顶板111的内表面上。
人体检测传感器107设于制冷室箱门103上，人体检测传感器107被配置为检测冰箱10周围的人体活动情况，也即检测气调保鲜装置100周围的人体活动情况。例如，可以检测是否有人体存在或者人体的存在持续时长。其中，人体检测传感器107可以包括红外人体传感器或者微波传感器等。人体检测传感器107设于制冷室箱门103上的位置可以根据需求设定，例如图1所示的制冷室箱门103的右上角；考虑到人体的身高，也可以设于制冷室箱门103的中间部位。
控制部108设于箱体101内，且与门开关传感器105、气体浓度传感器106、人体检测传感器107以及开合检测机构(磁控开关1131)都分别电连接。进而，控制部108可以获取门开关传感器105、气体浓度传感器106、人体检测传感器107以及开合检测机构的检测数据。控制部108可以是冰箱主控制板或者显示板(通常设置于制冷室箱门103上)；控制部108设于箱体101内的位置可以是箱体101背部或者侧部等，在此不做特殊限定。
继续参阅图5所示，控制部108可以包括以下部分，需要说明的是，图5示出的控制部108仅是一个示例，不应对本公开一些实施例的功能和使用范围带来任何限制。
如图5所示，控制部108(例如可以是冰箱10的显示板)包括处理器1081、存储器1082、总线1083以及接口1084。
处理器1081是以下硬件之一：通用中央处理器(Central Processing Unit，CPU)，微处理器(Microprocessor Unit，MPU)，芯片(chip)、微芯片(microchip)、集成电路(Integrated Circuit，IC)等。处理器1081可以为1个或多个。每个处理器1081内可以有一个或多个CPU。
储存器1082是以下硬件之一：随机存取存储器(random access memory，RAM)、闪存、只读存储器(read only memory，ROM)、可擦除可编程只读存储器(erasable programmable ROM，EPROM)、电可擦可编程只读存储器(electrically EPROM，EEPROM)、寄存器、硬盘、移动硬盘、只读光盘(CD-ROM)或者本领域熟知的任何其它形式的存储介质。储存器可以独立存在并通过总线与处理器相连，或者储存器可 以和处理器集成在一起。
总线(Bus)1083是由导线组成的传输线束，用作控制部108的各组件之间传递数据、信息、指令的传输通路。
接口(Interface)1084硬件上表现为与外部设备和网络进行连接的连接器。外部设备可以是键盘、鼠标、显示屏、扬声器等。例如，与外部设备连接时的接口1084可以是网线接口、USB接口(Universal Serial Bus Interface)。例如，与外部网络连接时接口1084可以是收发器；该外部网络可以是以太网、无线接入网(Radio Access Network，RAN)、无线局域网(Wireless Local Area Networks，WLAN)等。从而通过接口1084与用户的手机和电脑等可移动或不可以移动的终端设备连接，以便用户通过这些终端设备间接、远程控制冰箱。接口1084可以为1个或多个。
键盘1085、鼠标1086：通过键盘1085、鼠标1086等外部设备，用户可以设定和修改冰箱10内的保鲜气体的浓度阈值、冰箱10内物品的保鲜时长阈值、冰箱10的制冷温度以及气调动力组件140的运行时长，该浓度阈值、保鲜时长阈值、制冷温度以及运行时长将被保存在储存器1082中。
显示屏1087、扬声器1088：通过显示屏1087、扬声器1088等外部设备，可以向用户发出警报或提示。在一些实施例中，通过显示屏1087既可以输出、也可以输入。例如，当显示屏1087是触控显示屏时，用户也可以通过显示屏1087设定和修改冰箱10内的保鲜气体的浓度阈值、冰箱10内物品的保鲜时长阈值、冰箱10的制冷温度以及气调动力组件140的运行时长。
本公开一些实施例提供一种气调保鲜装置的控制方法，如图6所示，该气调保鲜装置的控制方法可以包括S210至S720。
S210，门开关传感器105确定制冷室102是否被打开；
在一些实施例中，门开关传感器105包括门动传感器，通过微波或者红外等检测手段检测门铰链104或者制冷室箱门103的旋转情况来判断门的开关状态，从而确定制冷室102是否被打开。在一些实施例中，门开关传感器包括压力传感器，通过检测门铰链104或者制冷室箱门103旋转时的压力来判断门的开关状态，从而确定制冷室102是否被打开。
S220，如果制冷室102未被打开，开合检测机构确定容置盒110与抽屉120所形成的空间是否密闭；
在一些实施例中，如图2和图3所示，开合检测机构包括设置于容置盒110上的磁控开关1131(例如干簧管等)以及设置于抽屉120上的磁性件121，通过磁性件121对磁控开关1131的磁吸力的大小，确定抽屉120是否开启，从而确定容置盒110与抽屉120所形成的空间是否密闭。在一些实施例中，开合检测机构为摄像头，通过摄像头实时监控确定容置盒110与抽屉120所形成的空间是否密闭。
通过确定制冷室102是否被打开，实时可靠地判断用户是否正在使用冰箱10；如果制冷室102未被打开时，则用户没有使用冰箱，再确定容置盒110与抽屉120是否密闭，从而可以在用户没有使用冰箱时，进一步根据容置盒110与抽屉120的密闭情况进行气体调节控制。可靠保证冰箱10的使用性能。但S210不是必须的，当在S210中检测到制冷室102被打开时，如果在S220中检测到容置盒110与抽屉120所形成的空间密闭，则表明用户正在使用冰箱的其他间室，而未使用包含气调保鲜装置100的间室。
S230，当容置盒110与抽屉120所形成的空间密闭时，气体浓度传感器106获取容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度，并发送给控制部108；
在一些实施例中，气体浓度传感器106可以直接获取保鲜气体(例如氮气)的浓度，也可以获取氧气浓度，从而根据氧气浓度反映保鲜气体的浓度。通过获取保鲜气体的浓度可以及时、准确确定容置盒110与抽屉120所形成的空间内的保鲜效果是否异常，进而可以及时进行容置盒110内的气体调节。
S240，控制部108确定保鲜气体的浓度是否低于预设的浓度阈值；
预设的浓度阈值可以用于反映容置盒110与抽屉120所形成的空间内的物品是否处于保鲜效果异常状态。也即，如果保鲜气体的浓度低于预设的浓度阈值，说明容置盒110与抽屉120所形成的空间内的物品处于保鲜效果异常状态，需要及时启动气调动力组件140调节容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度。
在一些实施例中，以预设的浓度阈值为80％为例进行说明，控制部108可以根据从气体浓度传感器106获取的保鲜气体(氮气)的浓度，直接确定保鲜气体(氮气)的浓度是否低于预设的浓度阈值80％；也可以根据从气体浓度传感器106获取的氧气的浓度，确定氧气的浓度是否小于等于19％，从而确定保鲜气体的浓度是否低于预设的浓度阈值80％。 考虑到空气中除了氮气和氧气外，还有其他气体的存在，因此当保鲜气体(氮气)的浓度达到预设的浓度阈值80％时，氧气的浓度大约为19％。当氧气浓度为大于19％时，表明保鲜气体(氮气)的浓度低于预设的浓度阈值80％。
S250，如果保鲜气体的浓度低于预设的浓度阈值，则人体检测传感器107确定气调保鲜装置100的周围是否有人体存在；当气调保鲜装置100的周围不存在人体，执行S260；否则，执行S310。
人体检测传感器107确定有无人体存在的动作，由保鲜气体的浓度低于预设的浓度阈值的条件触发，可以保证及时进行是否有人存在的确定。
人体检测传感器107确定气调保鲜装置100的周围是否有人体存在的操作可以是，人体检测传感器107检测气调保鲜装置100的预定距离范围内是否有人体存在，例如检测气调保鲜装置100的10米内是否有人体存在。
S260，控制部108控制启动气调动力组件140对容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度进行调节。
气调动力组件140启动后可以驱使容置盒110与抽屉120所形成的空间内的空气通过气调膜130，空气会有选择性地通过气调膜130。氧气通过气调膜130的速率大于氮气通过气调膜130的速率。从而相比于氮气，有更多的氧气通过气调膜130被排出至容置盒110与抽屉120所形成的空间外，实现在气调膜130的两侧分别富集保鲜气体(例如氮气)和氧气。即，从容置盒110抽出的气体中氧气含量较高，容置盒110内剩余气体中保鲜气体含量较高，由此调节容置盒110与抽屉120所形成的空间内含有的保鲜气体的浓度。
本公开一些实施例中，由于不像相关技术中那样在冰箱被打开后通过设定时间间隔启动气调动力组件重新进行气体调节，而是在监测到容置盒110与抽屉120所形成的空间内的保鲜效果异常后，在没有人体存在时，即可以开始气体调节。因此在本公开一些实施例中可以及时、准确地控制气调动力组件140进行气体调节，同时，避免气调动力组件140的运行噪音对用户的不良影响。实现气调保鲜装置100的保鲜性能与用户体验的协调，有效提升气调保鲜装置100的使用性能。
S310，人体检测传感器107获取人体的存在持续时长，并发送给控制部108；
获取人体的存在持续时长是在监测到容置盒110与抽屉120所形成的空间内的保鲜气体浓度低于预设的浓度阈值，并确定气调保鲜装置100的周围存在人体时进行的。在确定气调保鲜装置100的周围存在人体时，通过获取人体的存在持续时长，可以实时监测人体在冰箱10周围的活动持续情况。
S320，控制部108确定存在持续时长是否小于预设的保鲜时长阈值；当存在持续时长小于预设的保鲜时长阈值时，执行S330；否则执行S410。
保鲜时长阈值为反映抽屉120内的物品，在监测到容置盒110与抽屉120所形成的空间内的保鲜气体浓度低于预设的浓度阈值后，可以维持新鲜状态的时间范围。即在监测到容置盒110与抽屉120所形成的空间内的保鲜气体浓度低于预设的浓度阈值后，物品新鲜状态的持续时长大致等于该保鲜时长阈值(“大致”表明可能有10分钟或半小时左右的误差)，如果超过该保鲜时长阈值则物品开始变质腐败。
在该存在持续时长小于保鲜时长阈值时，如果使保鲜气体浓度大于或等于预设的浓度阈值，则抽屉120内的物品可有效恢复保鲜效果；但在该持续时长大于保鲜时长阈值时，之后即使保鲜气体浓度大于或等于预设的浓度阈值，抽屉120内的物品也难以有效恢复保鲜效果。
S330，控制部108控制气调动力组件140不启动。
当存在持续时长小于预设的保鲜时长阈值(例如30min、45min、60min、90min、120min等)，说明抽屉120内的物品失去保鲜氛围的持续时间还处在可以使物品有效恢复保鲜效果的时间范围内。此时，控制部108控制不启动气调动力组件140，可以在尽可能保证保鲜性能的情况下，进一步可靠地避免启动气调动力组件140的运行噪声对用户的影响。
S410，控制部108确定制冷动力组件是否处于运行状态；当制冷动力组件处于运行状态时，执行S420或S430；否则执行S510；
制冷动力组件为保持冰箱10的冷藏、冷冻、变温等功能的动力组件。制冷动力组件(例如，压缩机、制冷管路、冷媒、风扇等)用于调节冰箱10的制冷室102内的温度。
S420，控制部108控制气调动力组件140不启动。
气调保鲜装置100设置于冰箱中，由于制冷动力组件运行时也会发生振动噪声，如果气调动力组件140也同时运行，两者可能共振、共同发出噪声，影响冰箱10的整体性能和用户使用体验。
进而在上述存在持续时长大于预设的保鲜时长阈值时，可以在启动气调动力组件140之前先确定制冷动力组件是否处于运行状态。如果制冷动力组件处于运行状态，则控制部108控制不启动所述气调动力组件140，可以有效避免制冷动力组件与气调动力组件140的共振、共同发出噪声，有效保证冰箱的整体性能和用户使用体验。其中，制冷动力组件是否处于运行状态可以根据冰箱的控制部108中对制冷动力组件的启动控制状态确定或者通过在制冷动力组件上设置震动、温度检测传感器等确定。
在一些实施例中，S420和S330可以是同一个步骤。
S430，控制部108获取制冷室102的温度，并确定制冷室102内温度是否低于预设的制冷温度；
在一些实施例中，制冷室102内温度可以通过制冷室102内的温度传感器获取。在一些实施例中，该预设的制冷温度可以高于标准制冷效果的温度阈值，此时虽然在预设的制冷温度下冰箱10没有达到标准制冷效果，但是已经具有一定程度制冷效果。
S440，当制冷室内温度低于预设的制冷温度时，控制部108控制关闭制冷动力组件，并控制启动气调动力组件140。
当制冷室内温度低于预设的制冷温度时，说明制冷室内已经具有一定程度的制冷效果；同时，人体存在持续时长等于或大于预设的保鲜时长阈值时，说明抽屉内的物品超过可以有效恢复保鲜效果的时间范围。此时，控制部108关闭制冷动力组件，并启动气调动力组件140，既保证制冷效果，又可以保证保鲜效果在一定程度上的恢复，进一步保证用户体验和冰箱的整体性能。其中，制冷室内温度可以通过制冷室内的温度传感器获取。
S510，控制部108控制启动气调动力组件140。
在人体存在持续时长等于或大于预设的保鲜时长阈值时，保鲜效果可能会面临失效，此时，如果制冷动力组件处于停止状态，在控制部108启动所述气调动力组件140，可以及时保证保鲜效果，同时避免制冷动力组件及气调动力组件140的共振及共同发出噪声。
在一些实施例中，S510和S260可以是同一个步骤。
在一些实施例中，当控制部108控制启动气调动力组件140时，气调保鲜装置的控制方法还包括如下步骤：
S610，控制部108确定气调动力组件140的启动时长是否超过预设 的运行时长；当气调动力组件140的运行时长超过预设的运行时长时，执行S620；否则，执行S710；
S620，控制部108控制气调动力组件140停止运行。
预设的运行时长为预设的气调动力组件140单次运行的极限时长，例如，15min、18min、20min、30min等。在气调动力组件140的运行时长超过预设的运行时长时停止气调动力组件140，可以避免由于容置盒110密闭性失效、管路漏气、检测保鲜气体浓度的传感器发生故障等情况下，气调动力组件140长时间运行，而导致气调动力组件140长时间产生噪音、发热量大、寿命缩短。在一些实施例中，如果气调动力组件140的运行时长超过预设的运行时长，则冰箱10可以向用户发出警报。
S710，控制部108获取容置盒110与抽屉120所形成的空间内保鲜气体的浓度，并确定保鲜气体的浓度是否低于预设的浓度阈值；
在一些实施例中，S710和S240可以是同一个步骤。
S720，如果保鲜气体的浓度大于或者等于预设的浓度阈值，则控制部108控制气调动力组件140停止运行。
在一些实施例中，S720和S620可以是同一个步骤。
在一些实施例中，上述的步骤不是全部都必须。例如，可以省略S210和S220这两个步骤。或者，可以仅执行S230、S240、S250和S260这四个步骤。在一些实施例中，可以在S230～S260这四个步骤的基础上，继续执行S310～S330，而不执行其余的步骤。或者，可以在S230～S260和S310～S330这七个步骤的基础上，继续执行S410～S440，而不执行其余的步骤。或者，可以在S230～S260、S310～S330和S410～S440这十一个步骤的基础上，继续执行S610～S620，而不执行其余的步骤。在一些实施例中，可以在S230～S260这四个步骤的基础上，继续执行S610～S620，而不执行其余的步骤。或者，可以在S230～S260和S610～S620这六个步骤的基础上，继续执行S710～S720。
本公开的一些实施例提供了一种计算机可读存储介质(例如，非暂态计算机可读存储介质)，该计算机可读存储介质中存储有计算机程序指令，计算机程序指令在控制部108的处理器1071上运行时，使得处理器1071执行如上所述的气调保鲜装置的控制方法中的一个或多个步骤。
示例性地，上述计算机可读存储介质可以包括，但不限于：磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，CD(Compact Disk，压缩盘)、DVD(Digital Versatile Disk，数字通用盘)等)，智能卡和 闪存器件(例如，EPROM(Erasable Programmable Read-Only Memory，可擦写可编程只读存储器)、卡、棒或钥匙驱动器等)。本公开描述的各种计算机可读存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读存储介质。术语“机器可读存储介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
本公开的一些实施例还提供了一种计算机程序产品。该计算机程序产品包括计算机程序指令，在计算机上执行该计算机程序指令时，该计算机程序指令使计算机执行如上所述的气调保鲜装置的控制方法中的一个或多个步骤。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
