Description

冰箱的控制方法和冰箱 技术领域
本发明涉及冷藏冷冻装置，特别是涉及一种冰箱的控制方法和冰箱。
背景技术
现有一些冰箱内设置有保鲜盒，其内限定出一个密闭的保鲜空间。再通过抽出其内的氧气，形成利于食品保鲜的气体氛围。
因保鲜盒内部是密闭的，放入大量的绿色水果、蔬菜后，由于生物的呼吸作用，就会释出大量的水分。这样很容易使保鲜盒内部空间的空气先对湿度达到100％，继而产生凝露，导致保鲜空间内积水，影响使用效果。
发明内容
本发明的一个目的是要提供一种冰箱的控制方法，以解决保鲜盒内容易凝露积水的问题。
本发明的另一目的是要提供一种可实现上述控制方法的冰箱。
一方面，本发明提供了一种冰箱的控制方法，冰箱包括内壁设置有进风口和回风口的第一制冷间室，设置在第一制冷间室内且形成有保鲜空间的保鲜盒，以及风机，风机用于促使冷气经进风口吹入第一制冷间室，回风口用于将第一制冷间室内的空气引出，保鲜盒靠近回风口；控制方法包括：
当冰箱制冷直至第一制冷间室的温度达到设定温度时，停止制冷运行，关闭风机且持续第一预设时间；
开启风机并持续第二预设时间，以利用第一制冷间室的流向回风口的较高温度的回风加热保鲜盒。
可选地，开启风机并持续第二预设时间的步骤之后还包括：
关闭风机，并检测第一制冷间室在风机关闭时的温度，记为关机时刻温度；
根据关机时刻温度与设定温度，确定风机下次开启时刻；
在时间达到风机下次开启时刻时，开启风机。
可选地，根据关机时刻温度与设定温度，确定风机下次开启时刻的步骤包括：
判断关机时刻温度是否小于或等于设定温度；
若是，确定风机下次开启时刻为第三预设时间后；
若否，确定风机下次开启时刻为第四预设时间后，第四预设时间小于第三预设时间。
可选地，在时间达到风机下次开启时刻时，开启风机的步骤之后还包括：
风机的开启时间达到第二预设时间后，关闭风机。
另一方面，本发明还提供了一种冰箱，包括：
箱体，其限定有第一制冷间室，其为冷藏室，第一制冷间室的内壁设置有用于允许冷风吹入的进风口和允许空气流出的回风口；
保鲜盒，设置在第一制冷间室内且临近回风口，且限定有密闭的保鲜空间；
风机，用于促使冰箱制取的冷气经进风口吹入第一制冷间室；
控制器，其包括存储器以及处理器，存储器内存储有计算机程序，并且计算机程序被处理器执行时，用于实现以上任一项的控制方法。
可选地，冰箱还包括：
蒸发排水管，用于将冷却室内的冷凝水排出；
保鲜排水管，用于将保鲜盒内的积水向下引流，且下端接入蒸发排水管，并且保鲜排水管具有一先向下延伸，再向上弯折的“U”形段，以用于存水。
可选地，保鲜盒的内部底壁从其一侧向另一侧逐渐向下倾斜；且
保鲜排水管连接于保鲜盒内部底壁的高度较低的一侧，以利于积水流入保鲜排水管。
可选地，保鲜盒设置在第一制冷间室的底部；且
回风口开设在第一制冷间室后壁临近保鲜盒的顶面的位置。
可选地，箱体还限定出冷却室和风道，风道由风道部件限定出，风道部件竖立在箱体内部，风道部件前方为第一制冷间室，后方为冷却室；
冷却室内设置有蒸发器，风道连通冷却室和第一制冷间室；
风机安装在风道的后壁上，以用于将冷却室的冷气吹入风道，进而使冷气经进风口吹入第一制冷间室。
可选地，用于提高保鲜空间内氮气浓度的抽气泵和气调膜组件，抽气泵配置成将保鲜空间内的气体向外抽出，以使保鲜空间内的空气流向气调膜组件，并在气调膜组件的作用下使保鲜空间内空气中的部分或全部富氧气体经 由抽气泵排出保鲜空间。
本发明的冰箱中，第一制冷间室内设置有保鲜盒。保鲜盒内的保鲜空间是密闭的，瓜果蔬菜的呼吸作用产生较多水分在保鲜空间内累积。再加之是低温环境，容易使空气相对湿度升高至100％，产生凝露、滴水，积水甚至结霜等不利现象。本发明的控制方法中，冰箱先按常规设定程序进行制冷。当第一制冷间室的温度达到设定温度后，冰箱停止制冷(即压缩机停机)，风机也停止运行，以停止对第一制冷间室的冷气供应。风机停机第一预设时间后，蒸发器温度有一定回升，第一制冷间室的冷量也有一定消耗。此时再开启风机并持续开启第二预设时间，以重启第一制冷间室的风路循环，使得其温度相对较高的回风(冷量经食物时已经有较多消耗)经过保鲜盒，起到一定的加热作用(该加热只是使其温度不至于过低，不会影响到保鲜盒内的正常制冷需求)。保鲜盒内气温升高会使相对湿度降低，还能使保鲜盒内壁的可能产生的霜层融化。
进一步地，本发明的控制方法中，风机开启第二预设时间后，第一制冷间室以及其内的食物已经处于较低温度。此时关闭风机并检测第一制冷间室的关机时刻温度。若关机时刻温度小于等于设定温度，表明第一制冷间室的温度还是相对较低，需等待较长时间(第三预设时间)，使其温度有一定回升后再开启风机以再次利用回风对保鲜盒进行加热。若关机时刻温度大于设定温度，表明第一制冷间室的温度并不是很低，只需等待较短时间(第四预设时间)，即可使第一制冷间室的温度有回升，然后即可再次开启风机以利用回风对保鲜盒进行加热。总之，本发明的控制方法在冰箱停止制冷期间，两次开启风机以开启第一制冷间室的风路循环，利用回风对保鲜盒进行适当加热。
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冰箱结构示意图；
图2是根据本发明一个实施例的冰箱的示意性框图；
图3是根据本发明一个实施例的冰箱的后部结构示意图；
图4是根据本发明一个实施例的冰箱保鲜盒的结构示意图；
图5是根据本发明一个实施例的冰箱的控制方法的示意图；
图6是根据本发明一个实施例的冰箱的控制方法的流程图。
具体实施方式
本发明实施例首先提供了一种冰箱的控制方法。图1是根据本发明一个实施例的冰箱结构示意图。
如图1所示，冰箱包括箱体100、保鲜盒200以及风机400，可采用包括压缩机(未示出)、蒸发器500、冷凝器以及节流元件(未示出)的蒸气压缩制冷循环系统进行制冷。其中，箱体100限定有第一制冷间室101以用于储物。第一制冷间室101的内壁设置有进风口310和回风口320。风机400用于促使冷气经进风口310吹入第一制冷间室101，回风口320用于将所述第一制冷间室101内的空气引出。冷气经进风口310进入第一制冷间室101，与食物换热后，温度升高后，从回风口320流出第一制冷间室101继续接受冷却降温，然后再经进风口310进入第一制冷间室101，如此不断循环，完成第一制冷间室101的制冷，上述过程构成第一制冷间室101的风路循环。
图5是根据本发明一个实施例的冰箱的控制方法的示意图。如图5所示，本发明的控制方法可包括如下步骤：
步骤S502：当冰箱制冷直至所述第一制冷间室101的温度达到设定温度时，停止制冷运行，关闭风机400且持续第一预设时间。
步骤S504：开启风机400并持续第二预设时间。
上述步骤中，所述的设定温度是指冰箱的常规制冷控制程序中，设定的第一制冷间室101的目标温度。冰箱的制冷运行指的是开启压缩机以进行制冷进程。第一制冷间室101的温度达到设定的所述目标温度后，即停止制冷运行，也就是使压缩机停机。压缩机停机期间，蒸发器500还处于较冷状态，即还有余冷。
保鲜盒200内的保鲜空间201是密闭的。瓜果蔬菜的呼吸作用将产生较多水分，水分无法向外散发，将在保鲜空间201内累计。再加之保鲜空间201是低温环境，容易使空气相对湿度升高，甚至达到100％。这样就会产生凝 露、滴水，积水甚至结霜等不利现象。
上述控制方法中，冰箱先按常规设定程序进行制冷。当第一制冷间室101的温度达到设定温度后，冰箱停止制冷运行(即压缩机停机)，风机400也停止运行，以停止对第一制冷间室101的冷气供应。风机400停机第一预设时间后，蒸发器500温度有一定回升，第一制冷间室101的冷量也有一定消耗。此时再开启风机400并持续开启第二预设时间，以重启第一制冷间室101的风路循环，使得其温度相对较高的回风(冷量经食物时已经有较多消耗)经过保鲜盒200，起到一定的加热作用(该加热只是使其温度不至于过低，不会影响到保鲜盒200内的正常制冷需求)。保鲜盒200内气温升高会使相对湿度降低，还能使保鲜盒200内壁的可能产生的霜层融化。
可对不同冰箱进行具体试验，以确定第一预设时间和第二预设时间的合理取值。例如使第一预设时间为5min，使第二预设时间为10min。
在一些可选实施例中，可以通过对上述步骤作进一步优化和配置以实现更好的技术效果，以下结合对本实施例的一个可选执行流程的介绍对本实施例的冰箱的控制方法进行详细说明，该实施例仅为对执行流程的举例说明，在具体实施时，可以根据具体实施需求对部分步骤的执行顺序、运行条件进行修改。
图6是根据本发明一个实施例的冰箱的控制方法的流程图。如图6所示，该实施例的控制方法依次执行以下步骤：
步骤S602：冰箱制冷直至所述第一制冷间室101的温度Ts达到设定温度时，停止制冷运行，关闭风机400且持续第一预设时间。
步骤S604：开启风机400并持续第二预设时间。
步骤S606：关闭所述风机400，并检测第一制冷间室101在风机400关闭时的温度，记为关机时刻温度。
该步骤中，利用设置在第一制冷间室101内的温度传感器970检测关机时刻温度。根据关机时刻温度来确定风机400下次开启时刻。具体参见下述步骤。
步骤S608：判断关机时刻温度是否小于或等于前述第一制冷间室101的设定温度Ts。若成立，执行步骤S610。若不成立，执行步骤S612。
步骤S610：确定风机400下次开启时刻为第三预设时间后，然后执行步骤S614。即关机时间达第三预设时间后，即在此开启风机。
步骤S612：确定风机400下次开启时刻为第四预设时间后，然后执行步骤S614。
上述两步骤中，第四预设时间小于第三预设时间。
步骤S614：在时间达到风机400下次开启时间后，开启风机400。
步骤S615：在风机400开启时间达第二预设时间后，关闭风机400。
该实施例的控制方法中，风机400开启第二预设时间后，第一制冷间室101以及其内的食物已经处于较低温度。此时关闭风机400并检测第一制冷间室101的关机时刻温度。若关机时刻温度小于等于设定温度，表明第一制冷间室101的温度还是相对较低，需等待较长时间(第三预设时间)，使其温度有一定回升后再开启风机400以再次利用回风对保鲜盒200进行加热。若关机时刻温度大于设定温度，表明第一制冷间室101的温度并不是很低，只需等待较短时间(第四预设时间)，即可使第一制冷间室101的温度有回升，然后即可再次开启风机400以利用回风对保鲜盒200进行加热。总之，本发明的控制方法在冰箱停止制冷期间，两次开启风机400以开启第一制冷间室101的风路循环，利用回风对保鲜盒200进行适当加热。
可对不同冰箱进行具体试验，以确定第三预设时间和第四预设时间的合理取值。例如使第三预设时间为8min，使第二预设时间为4min。
本发明实施例还提供了一种冰箱。图2是根据本发明一个实施例的冰箱的示意性框图；图3是根据本发明一个实施例的冰箱的后部结构示意图；图4是根据本发明一个实施例的冰箱保鲜盒200的结构示意图。
如图1所示，冰箱一般性地可包括箱体100、保鲜盒200、风机400。其中，箱体100限定有第一制冷间室101，第一制冷间室101为冷藏室。第一制冷间室101的内壁设置有允许冷风吹入的进风口310和允许空气流出的回风口320。保鲜盒200设置在第一制冷间室101内，且限定有密闭的保鲜空间201，以用于放置新鲜蔬菜和水果等。风机400用于促使冰箱制取的冷气经进风口310吹入第一制冷间室101，图1中用箭头示意了风向。
箱体100还限定出冷却室600和风道301。风道301由风道部件300限定出。风道部件300竖立在箱体100内部，风道部件300前方为前述的第一制冷间室101，后方为冷却室600。冷却室600内设置有蒸发器500，蒸发器500用于制取冷气。风道301连通冷却室600和第一制冷间室101。风道301的前壁与第一制冷间室101的后壁为同一个壁。风机400安装在风道301的 后壁上，以用于将冷却室600的冷气吹入风道301，进而使冷气经进风口310吹入第一制冷间室101。可以这样理解，风机400开启时，实现空气的强制对流，冷却室600的冷气源源不断进入风道301。风机400关闭时，气流基本停滞。可使保鲜盒200的后部顶壁构成冷却室600的底壁，以便引入冷量用于制冷。
可使保鲜盒200临近回风口320设置，以利用第一制冷间室101回风加热保鲜盒200。例如图1，可使保鲜盒200设置在第一制冷间室101的底部，使回风口320开设在第一制冷间室101后壁临近保鲜盒200的顶面的位置，以便回风从保鲜盒200顶面扫过。
如图2所示，冰箱还包括控制器800。控制器800包括处理器810以及存储器820。存储器820内存储有计算机程序821。并且，计算机程序821被运行时，使得控制器800执行上述任一实施例中的冰箱的控制方法。
本实施例的存储器820可以是诸如闪存、EEPROM、EPROM、硬盘或者ROM之类的电子存储器，存储器820具有用于执行上述方法中的任何方法步骤的计算机程序821的存储空间。通过运行计算机程序821，控制器800执行上述描述的方法中的各个步骤，实现冰箱的控制。
在一些实施例中，如图1所示，第一制冷间室101设置在箱体100上部，以作为冷藏室。箱体100同时还限定有变温室102以及冷冻室103。前述的冷却室600、蒸发器500和风道301仅用于与冷藏室配合。变温室102和冷冻室103后侧设置有另一冷却室720，其内设置有另一蒸发器740。冷却室720前方设置有风道730。风道730的后壁设置有另一风机710，以用于将冷却室720内的冷气吹入风道730。风道730的前壁开设有连通变温室102的送风口731以及连通冷冻室103的送风口732，以分别向变温室102和冷冻室103送风。
在一些实施例中，如图3所示，冰箱还包括蒸发排水管910以及保鲜排水管920。其中，蒸发排水管910用于将冷却室600内的冷凝水排出，最终流至蒸发皿930内完成蒸发。冷却室600的冷凝水主要为蒸发器500表面的霜层融化而来。保鲜排水管920用于将保鲜盒200内的积水向下引流。保鲜排水管920上端插入保鲜盒200内部，下端接入蒸发排水管910，以用于将保鲜盒200内的积水引入蒸发排水管910，以缩短其长度。并且，可使保鲜排水管920具有一先向下延伸，再向上弯折的“U”形段921，以用于存水。 在“U”形段921内存水的目的是为了避免保鲜盒200通过蒸发排水管910以及保鲜排水管920产生漏气，影响其密闭效果。
如图4所示，可使保鲜盒200的内部底壁260从其一侧向另一侧逐渐向下倾斜，使保鲜排水管920连接于保鲜盒200内部底壁260的高度较低的一侧，以利于积水在重力作用下向下流，流入保鲜排水管920。如图4，保鲜盒200内部底壁260前高后低，保鲜排水管920连接于保鲜盒200的后部。
在一些实施例中，如图1所示，冰箱还设置有用于提高保鲜空间201内氮气浓度的抽气泵240和气调膜组件230，抽气泵240配置成将保鲜空间201内的气体向外抽出，以使保鲜空间201内的空气流向气调膜组件230，并在气调膜组件230的作用下使保鲜空间201内空气中的部分或全部富氧气体经由抽气泵240排出保鲜空间201。图1仅是示意性地画出了抽气泵和气调膜组件，并未限定两者一定设置在图1所在的位置。
具体地，气调膜组件230具有气调膜和富氧气体收集腔，且气调膜的一侧朝向富氧气体收集腔，以在富氧气体收集腔的压力小于气调膜的另一侧的压力时，使气调膜的另一侧的空气中的富氧气体透过气调膜进入富氧气体收集腔。
抽气泵240配置成将保鲜空间201内的气体向外抽出，以使富氧气体收集腔的压力小于保鲜空间201的压力，使保鲜空间201内的空气流向气调膜组件230，并在气调膜组件230的作用下使保鲜空间201内空气中的部分或全部富氧气体经由抽气泵240排出保鲜空间201。上述富氧气体大部分情况下为氧气。
在本实施例中，气调膜能够选择性地透过保鲜空间201内的富氧气体，而将空气中余下的氮气保留在保鲜空间201内部，从而提高保鲜空间201内部的氮气浓度。本发明的冰箱可使保鲜空间201内形成富氮贫氧以利于食物保鲜的气体氛围，该气体氛围通过降低果蔬保存空间内氧气的含量，降低果蔬有氧呼吸的强度，同时保证基础的呼吸作用，防止果蔬进行无氧呼吸，从而达到果蔬长期保鲜的目的。而且，该气体氛围还具有大量的氮气等气体，还不会降低保鲜空间201内物品的受冷效率，可使果蔬等有效得到储存。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或 修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
