本公开提供了一种果蔬保鲜设备,在一些实施例中,如图1所示,包括:柜体1,柜体1内设有用于存放果蔬的存储腔,存储腔内设有第一隔板14,用于将存储腔沿第一方向x分隔为冷藏库12和缓存库13,冷藏库12靠近安装腔11设置,第一隔板14上设有可开闭的第一门15,柜体1在缓存库13对应的区域设有可开闭的第二门16。
其中,柜体1可以为长方体结构,例如第一方向x可以为柜体1的长度方向,由此分隔出的冷藏库12和缓存库13均可避免形成狭长的空间,利于存放果蔬;可选地,第一方向x也可以为第二方向y或第三方向z。
冷藏库12用于长期存放果蔬,缓存库13用于缓存放置果蔬,例如在果蔬进入冷藏库12先在缓存库13中预冷,或者果蔬在移出冷藏库12后先在缓存库13中暂存。
较优地,所述冷藏库12的体积大于缓存库13的体积,冷藏库12作为主要的冷藏存储空间,缓存库13只起到果蔬临时放置的存储空间。可选地,冷藏库12的体积小于或者等于缓存库13的体积。
例如,第二门16可设在柜体1沿第一方向x的端部,远离冷藏库12设置,以减 小对冷藏库12的影响。第一门15的面积可小于柜体1沿第一方向x的端部的面积。第一门15的面积可小于第一隔板14的面积。第一门15和第二门16中的至少一个可通过转动或推拉的方式实现开闭。
该实施例通过增设缓存库13,果蔬在采摘后,可以先放入缓存库13进行预冷,在适当降温后再放入冷藏库12内,不仅可保障果蔬迅速降温导致口感受损,也可防止外面较热的果蔬直接放入冷藏库12造成温度波动,影响冷藏库12中已存放果蔬的低温贮存环境,还可防止在果蔬进出柜体时第一门15打开影响冷藏库12内的低温贮存环境。果蔬在出库时,可以先从冷藏库12移出至缓存库13,使果蔬逐渐升温,可保障果蔬水分散失,并预先放在缓存库13中方便随时取出,而且,在打开第一门15取出果蔬时也不太影响冷藏库12内的低温贮存环境。由此,可保证果蔬贮存的新鲜度,也可降低果蔬保鲜设备的能耗。
在一些实施例中,第一门15和第一隔板14中的至少一个采用隔热材料。
其中,例如,柜体1可采用发泡材料,第一门15和第一隔板14中的至少一个也可采用发泡材料。隔热材料具有较高的隔热系数,可减少冷藏库12和缓存库13之间的温度传递。
该实施例能够减小冷藏库12和缓存库13之间的温度传递,易于精确地控制冷藏库12和缓存库13内的目标温度,从而保证果蔬贮存的新鲜度。通过设置隔热材料,解决了进出货或其他外界因素对冷藏库12温度造成波动的问题,保证库温恒定。
在一些实施例中,在第二门16处于打开状态的情况下,第一门15处于关闭状态;和/或在第一门15处于打开状态的情况下,第二门16处于关闭状态。
该实施例在打开第二门16使果蔬进出柜体1的过程中,使第一门15处于关闭状态,可防止外部热量影响冷藏库12的温度,易于保证冷藏库12的低温贮存环境;在第一门15打开实现冷藏库12和缓存库13之间果蔬转移时,使第二门16处于关闭状态,可防止外部热量影响柜体1内的整体制冷环境。
在一些实施例中,果蔬保鲜设备还包括:第一温度传感器,用于检测冷藏库12内的温度;和/或第二温度传感器,用于检测缓存库13内的温度。通过设置温度传感器,可对两个库内的温度进行精确控制。
在一些实施例中,果蔬保鲜设备还包括控制器,控制器被配置为在进货环节,果蔬在缓存库13内预冷至T≤T+△T1的情况下,发出允许第一门15开启的信号,以使果蔬从缓存库13转运至冷藏库12进行冷藏。其中,T为高于设定温度区间后制 冷设备开启的温度,△T1为允许高于T的阈值,通过设置△T1,即使T稍微高于T,也在可接受范围内。
一般而言,冷藏库12内的温度低于缓存库13,该实施例能使果蔬在缓存库13内预冷至一定温度的情况下,设备可发出提醒,可开启第一门15允许果蔬从缓存库13放入冷藏库12进行冷藏。不仅可保障果蔬迅速降温导致口感受损,也可防止外面较热的果蔬直接放入冷藏库12造成温度波动,影响冷藏库12中已存放果蔬的低温贮存环境,还可防止在果蔬进出柜体时第一门15打开影响冷藏库12内的低温贮存环境。
在一些实施例中,控制器被配置为在出货环节,第一门15打开供果蔬从冷藏库12转运至缓存库13后,在冷藏库12内的温度T≥T+△T2的情况下,发出需要使第一门15关闭的信号,并在T≤T的情况下发出允许第一门15开启的信号;其中,T为高于设定温度区间后制冷设备开启的温度,T为低于设定温度区间后制冷设备停止工作的温度,△T2为允许高于T的阈值,△T2与△T1相互独立,通过设置△T2,即使T稍微高于T,也在可接受范围内。
该实施例在果蔬出货时,先从冷藏库12转运至缓存库13进行缓存,当T≥T+△T2的情况下,说明冷藏库12内的温度由于第一门15打开下降较多,此时设备可提醒第一门15需立即关闭。在T≤T的情况下,说明冷藏室12恢复到较低的温度,允许第一门15再次开启,进行下一次转运。在第一门15关闭后,果蔬可从缓存库13运输至柜体1外。
通过增设隔热材料,设置缓存库,智能控制第一门开启,保证冷藏库的温度维持在设定值,避免进出货或其他外界因素对库温造成波动。
在一些实施例中,柜体1内设有第二隔板17,用于在柜体1内分隔出安装腔11和所述存储腔。例如,第二隔板17可垂直于第一方向x设置,第一隔板14和第二隔板17间隔设置。安装腔11内用于放置制冷设备。
在一些实施例中,存储腔内设有沿第一方向x延伸的风道2,风道2的侧壁上在冷藏库12和缓存库13对应的区域都设有出风孔21。
其中,风道2的进风端可抵于第二隔板17,出风端可与柜体1沿第一方向x的端部间隔预设距离。出风孔21可密布多个,以实现均匀出风。出风孔21可以为细孔,以实现冷风均匀吹出。
在一些实施例中,风道2设在存储腔的顶部。在气流吹出后,风道与存放在存储腔底部的果蔬之间循环对流,以使果蔬均匀受冷,且不会占用果蔬的存放空间。
在一些实施例中,制冷设备包括冷风机3,设在安装腔11内,且冷风机3的出风口与风道2的进风口连通。冷风机3也可设在安装腔的顶部,第二隔板17上可设有通孔供气体进入风道2内。冷风机3可安装于第二隔板17。
在一些实施例中,风道2为布袋风道,布袋风道沿第二方向y间隔设置多个,第二方向y在水平面内垂直于第一方向x。布袋风道材质柔软,成本低,重量轻,出风孔21可设在布袋风道沿第二方向x的两侧,或者整个周向都可设置。布袋风道可通过悬挂件固定于柜体1的顶壁。
在一些实施例中,制冷设备包括压差风机4,设在安装腔11内,且压差风机4的出风口与冷藏库12连通。第二隔板17上可设置通孔,以使气流进入冷藏库12。压差风机4可安装于第二隔板17。
压差风机4可实现较大的风量,在存储腔底部堆放果蔬情况下,可对气流进行扰动,实现更好的制冷效果,防止果蔬堆积造成底部温度较高。
果蔬采摘后,需快速预冷后冷藏存储,其中预冷速度极大的影响果蔬存放时间,所以预冷阶段需制冷量大、风量大,但冷藏存储阶段,大风量的冷风会加速水分流失。通过同时设置压差风机4和冷风机3,解决了果蔬预冷阶段和存储阶段制冷量、风量需求不同的问题。采用双送风方式,实现大风量压差预冷和均匀式渗透冷藏,满足果蔬各种存储需求。
在一些实施例中,压差风机4设在安装腔11沿第三方向z的中间区域,第三方向z与高度方向一致。
在一些实施例中,果蔬保鲜设备还包括第一风阀5,可开闭地设在风道2内,第一风阀5沿第一方向x设在冷藏库12和缓存库13之间的位置,被配置为在打开状态下允许风道2内的气流到达缓存库13;和/或果蔬保鲜设备还包括第二风阀6,可开闭地设在风道2的出风端,被配置为在打开状态下允许风道2内的气流从端部到达缓存库13,风道2的出风端与柜体1沿第一方向x的端壁之间具有预设距离。可选地,第一风阀5和第二风阀6的开度可调。
该实施例通过设置第一风阀5,可灵活地控制是否向缓存库13内均匀出风,以实现保持缓存库13的温度;通过设置第二风阀6,可灵活地控制是否从风道2端部向缓存库13内快速出风,以实现快速制冷;通过调控风道两个风阀的开闭状态以及开度,并配合调节压缩机频率,实现利用一个制冷系统同时控制两个库房温度均达到设定值。
在一些实施例中,制冷设备包括冷凝机组7,设在安装腔11内,冷凝机组7包括冷凝器71和压缩机72。冷凝机组7可设在安装腔11的底部区域。制冷设备还可设有蒸发器,图中未示意出。
其次,本公开提供了一种基于上述实施例果蔬保鲜设备的控制方法,在一些实施例中,包括:
在进货环节,果蔬在缓存库13内预冷至T≤T+△T1的情况下,发出允许第一门15开启的信号,以使果蔬从缓存库13转运至冷藏库12进行冷藏;和/或
在出货环节,在第一门15打开供果蔬从冷藏库12转运至缓存库13后,在冷藏库12内的温度T≥T+△T2的情况下,发出需要使第一门15关闭的信号,并在T≤T的情况下发出允许第一门15开启的信号。
该实施例在进货环节,能使果蔬在缓存库13内预冷至一定温度的情况下,设备可发出提醒,可开启第一门15允许果蔬从缓存库13放入冷藏库12进行冷藏。不仅可保障果蔬迅速降温导致口感受损,也可防止外面较热的果蔬直接放入冷藏库12造成温度波动,影响冷藏库12中已存放果蔬的低温贮存环境,还可防止在果蔬进出柜体时第一门15打开影响冷藏库12内的低温贮存环境。
在出货环节,先从冷藏库12转运至缓存库13进行缓存,当T冷≥T开+△T2的情况下,说明冷藏库12内的温度由于第一门15打开下降较多,此时设备可提醒第一门15需立即关闭。在T冷≤T停的情况下,说明冷藏室12恢复到较低的温度,允许第一门15再次开启,进行下一次转运。在第一门15关闭后,果蔬可从缓存库13运输至柜体1外。
在一些实施例中,控制方法还包括:
在存货环节,且果蔬不在冷藏库12和缓存库13之间转运的情况下,使第一门15处于关闭状态。
该实施例能够在存货环节,使两个库的温度便于独立控制,保证需求的温度。
在一些实施例中,果蔬保鲜设备包括风道2、冷凝机组7、冷风机3、压差风机4、第一风阀5和第二风阀6,风道2在与冷藏库12和缓存库13对应的区域都设有出风孔21;冷凝机组7包括冷凝器71和压缩机72,冷风机3的出风口与风道2的进风口连通,压差风机4的出风口与冷藏库12连通;第一风阀5可开闭地设在风道2内,被配置为在打开状态下允许风道2内的气流到达缓存库13;第二风阀6可开闭地设在风道2的出风端,被配置为在打开状态下允许风道2内的气流从端部到达缓存库13; 在存货环节:
在果蔬仅存储于缓存库13的情况下,控制方法还包括第一调温步骤:根据缓存库13的温度T,控制冷凝机组7的工作状态、冷风机3的开关状态、压差风机4的工作状态、第一风阀5的开闭状态和第二风阀6的开闭状态中的至少一种;或者
在果蔬仅存储于冷藏库12的情况下,控制方法还包括第二调温步骤:根据冷藏库12的温度T,控制冷凝机组7的工作状态、冷风机3的开关状态、压差风机4的工作状态、第一风阀5的开闭状态和第二风阀6的开闭状态中的至少一种;或者
在果蔬同时存储于冷藏库12和缓存库13的情况下,控制方法还包括第三调温步骤:根据冷藏库12的温度T冷和缓存库13的温度T缓,控制冷凝机组7的工作状态、冷风机3的开关状态、压差风机4的工作状态、第一风阀5的开闭状态和第二风阀6的开闭状态中的至少一种。
其中,在果蔬仅存储于缓存库13的情况下,适用于果蔬存放时间不长,或者存放量不多的场合,便于果蔬随时灵活转运。在果蔬仅存储于冷藏库12的情况下,适用于果蔬需要长期冷藏,例如存储反季果蔬或者需要延期销售。在果蔬同时存储于冷藏库12和缓存库13的情况下,既有需要长期冷藏的果蔬,又有需要灵活转运的果蔬。对于不同的情况,因为处于制冷状态的库不同,因此采用了不同的调温控制方法。
在一些实施例中,第一调温步骤包括:
使冷凝机组7处于开启状态;和/或
使冷风机3处于开启状态;和/或
使第一风阀5和第二风阀6处于全开状态;和/或
使压缩机72的频率根据缓存库13的温度T自动调节。
该实施例在第一门15关闭的情况下,通过上述各部件的状态调节,只对放置果蔬的缓存库13进行温度调节,保证缓存库13的温度。
在一些实施例中,如图2所示,第二调温步骤包括:
在T≥T1,且T1≥T的情况下,使冷凝机组7处于开启状态;和/或冷风机3和压差风机4均处于开启状态;和/或使第一风阀5和第二风阀6全部处于关闭状态;和/或使压缩机72的频率根据冷藏库12的温度T自动调节。
该实施例使冷凝机组、冷风机、压差风机开启,第一风1和第二风阀全关,压缩机根据T自动进行频率调节,进行压差预冷;冷凝机组和冷风机使冷藏库内温度降低,压差风机风量大,可加快温度扰动,使冷风在果蔬内快速循环,实现大规模果蔬 存储的快速预冷。
在一些实施例中,如图2所示,第二调温步骤包括:
在T<T≤T2,且T2<T的情况下,使冷凝机组处于开启状态;和/或使冷风机3处于开启状态,且压差风机4处于关闭状态;和/或使第一风阀5和第二风阀6全部关闭;和/或使压缩机72的频率根据冷藏库12的温度T自动调节。
该实施例使压差风机关闭,压缩机根据T自动进行频率调节,通过冷风机进行渗透冷藏;冷风机外联多个风道,该风道布置在上方,两侧可均匀开孔,冷风通过两侧细孔均匀吹出,使冷藏库12内温度场均匀,同时降低风速,避免吹到果蔬表面的风速过高,加速水分流失。
在一些实施例中,如图2所示,第二调温步骤包括:
在T≤T,使冷凝机组7处于关闭状态;和/或使冷风机3和压差风机4均处于关闭状态;和/或使第一风阀5和第二风阀6均处于关闭状态。
该实施例能够在冷藏库12内温度较低已经满足制冷设备的停机温度时,使各设备停止工作,降低能耗,也防止温度更低影响果蔬品质。
在一些实施例中,如图3所示,在果蔬同时储存在冷藏库12和缓存库13时,压差风机的控制如第二调温步骤。第三调温步骤包括:
在T≥T,且T≥T的情况下,使冷凝机组7处于开启状态;和/或使冷风机3处于开启状态,且压差风机4处于关闭状态;和/或使第一风阀5处于全部打开状态,且使第二风阀6处于关闭状态;和/或使压缩机72以最大频率运行;由此,在冷藏库12和缓存库13温度均较高的情况下,因为冷藏库12有果蔬,为了减少水分流失,压差风机4不开启,使第一风阀5全部打开,可在通过风道2实现均匀出风的情况下,以最快的速度制冷;
或者在T≥T,且T<T<T的情况下,使冷凝机组7处于开启状态;和/或使冷风机3处于开启状态,且压差风机4处于关闭状态;和/或使第一风阀5开启a1%,且使第二风阀6处于关闭状态;和/或使压缩机72的频率根据冷藏库12的温度T自动调节,a1%是根据当前温度需求计算的开度值;由此,在冷藏库12温度较高,且缓存库13温度适中的情况下,可使第一风阀5处于部分打开状态,第二风阀6关闭,以减少进入缓存库13中的冷风,压缩机72的频率调节主要以冷藏库12的温度调节,主要调节目标为使冷藏库12的温度降低至目标温度,缓存库13的温度缓慢降低;
在T≥T,且T<T的情况下,按照第二调温步骤进行调节,此时由于缓存库温度已降低至满足要求,此时仅需单独控制冷藏库,相当于果蔬只存放冷藏库的情况。
在一些实施例中,如图3所示,第三调温步骤包括:
在T<T<T,且T≥T的情况下,使冷凝机组7处于开启状态;和/或使冷风机3处于开启状态,且压差风机4处于关闭状态;和/或使第一风阀5处于全部打开状态,且使第二风阀6开启a2%,a2%是根据当前温度需求计算的开度值;和/或使压缩机72的频率根据缓存库13的温度T、冷藏库12的温度T冷、T和T确定。
该实施例能够在冷藏库12温度适中,且缓存库13温度较高的情况下,可使第一风阀5全部打开,第二风阀6处于部分打开状态,以使较多的冷风进入缓存库13,第二风阀6关闭,以增加进入缓存库13中的冷风。由于冷藏库12体积较大,需要冷量较大,虽然温度适中仍可进行调节,因此,压缩机72的频率可综合根据T、T冷、T和T确定,主要调节目标为使缓存库13尽快降低至目标温度,冷藏库12缓慢降低至目标温度。
在一些实施例中,使压缩机72的频率根据缓存库13的温度T、冷藏库12的温度T冷、T和T确定包括:
在T-T>T-T的情况下,压缩机72的频率根据第一温度值确定,第一温度值为:(T+T)*[T-T/(T-T)];或者
在T-T=T-T的情况下,压缩机72的频率按照(T+T)/2为检测温度进行控制;

在一些实施例中,第三调温步骤包括:
在T<T<T,T≤T的情况下,按照第二调温步骤进行调节,在缓存库温度降低至满足要求的情况下,只对冷藏库进行控制,相对于果蔬只存放于冷藏库的情况。
在一些实施例中,在果蔬同时存储于冷藏库12和缓存库13的情况下,第三调温步骤包括:
在T≤T,且T≥T的情况下,按照第一调温步骤进行调节,在冷藏库温度降低至满足要求的情况下,只对缓存库进行控制,相对于果蔬只存放于缓存库的情况;或者
在T≤T,且T<T的情况下,使冷凝机组7处于关闭状态;和/或使冷风机3和压差风机4均处于关闭状态;和/或使第一风阀5和第二风阀6均处于关闭状态。在两个库的温度均降低至满足要求的情况下,使各部件都关闭,可降低能耗。
