Description

一种冷冻冷藏装置及其除霜控制方法 技术领域
本发明涉及蒸发器除霜技术,特别是涉及一种冷冻冷藏装置及其除霜控制方法。
背景技术
通常情况下,冰箱等冷冻冷藏装置在运行一段时间后,其蒸发器表面会结一层霜。该霜层会影响蒸发器与冰箱内空气之间的热交换,降低蒸发器制冷效率,因此冰箱运行一段时间后必须进行除霜。
现有技术中,通常采用加热的方式对蒸发器进行除霜。然而,除霜过程会产生大量的热气,该热气通常会通过进风口进入冰箱储物间室内部,一方面,导致热气中所含热量的浪费,另一方面,会导致储物间室内的温度上升,影响食物的保鲜和冷冻时间。
发明内容

本发明的冷冻冷藏装置中,由于连通冷却室和储物间室的供给风路中设有供给风门,连通冷却室的送气开口部和其返气开口部的除霜回风路中设有除霜回风风门,在对冷却室的蒸发器进行除霜时,可通过供给风门阻断供给风路,避免除霜加热器加热除霜时产生的热气通过供给风路流入储物间室内,避免储物间室内的温度因除霜热气而尝试,延伸了食物的储藏时间;并且,可通过除霜回风风门打开除霜回风路,使除霜时产生的热气依次通过送气开口部、除霜回风路和返气开口部返回至位于冷却室内的蒸发器处,以再次利用热气对蒸发器进行循环除霜,从而充分有效地利用了热气中所含的热 量,对蒸发器进行高效除霜。
进一步地,由于本发明的冷冻冷藏装置还包括连通冷却室和环境空间的排放风路,且排放风路中设有排放风门,在蒸发器循环除霜结束后,可通过排放风门打开排放风路,使蒸发器循环除霜结束后残留的热气通过排放风路排放至环境空间,从而进一步避免了残留热气进入储物间室内引起温度拨动。
进一步地,由于本发明的冷冻冷藏装置可充分有效地利用除霜加热器对蒸发器加热除霜时产生的热气,并且能够将除霜结束后残留的热气排放至环境空间,因此,蒸发器除霜操作对储物间室内的温度影响较小,蒸发器除霜结束后,再次对储物间室进行制冷时,可在较短时间内使储物间室内的温度恢复至除霜之前的温度,从而降低了冷冻冷藏装置的能耗。
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。

具体实施方式
图1是根据本发明一个实施例的冷冻冷藏装置的示意性结构图。如图1所示,冷冻冷藏装置1包括箱体100和枢转地连接到箱体100的门体200。其中箱体100内部限定有至少一个用于储存物品的储物间室、供给风路、返回风路和冷却室40。供给风路配置成向至少一个储物间室供给冷却气流。返回风路配置成使来自至少一个储物间室的气流流过。冷却室40具有用于使其内部的空气向供给风路流出的送气开口部和用于使来自返回风路的空气流入的返气开口部,且其内部设置有用于对从返气开口部流入其中的空气进行冷却的蒸发器41、用于驱动冷却室40内的空气朝向送气开口部流动的风机42和设置在蒸发器41上的除霜加热器43。特别地,箱体100内还限定有除霜回风路60,其位于冷却室40的后面,且连通冷却室40的送气开口部和返气开口部。供给风路和除霜回风路60内分别设置有供给风门和除霜回风风门61,以选择性地导通和/或阻断供给风路和除霜回风路60。
本发明的冷冻冷藏装置1由于在连通冷却室40和储物间室的供给风路中设有供给风门,连通冷却室40的送气开口部和其返气开口部的除霜回风路60中设有除霜回风风门61,在对冷却室40的蒸发器41进行除霜时,可通过供给风门阻断供给风路,避免除霜加热器43加热除霜时产生的热气通过供给风路流入储物间室内,避免储物间室内的温度因除霜热气而尝试,延伸了食物的储藏时间;并且,可通过除霜回风风门61打开除霜回风路60,使除霜时产生的热气依次通过送气开口部、除霜回风路60和返气开口部返回至位于冷却室40内的蒸发器41处,以再次利用热气对蒸发器41进行循环除霜,从而充分有效地利用了热气中所含的热量。
在本发明的一些实施例中,如图1所示,冷冻冷藏装置1还包括排放风路50,其分别与除霜回风路60和环境空间连通,以供流经除霜回风路60的空气直接排放至环境空间。
进一步地,排放风路50中还设置有排放风门51,以选择性地导通和/阻断排放风路50。在蒸发器41循环除霜结束后,除霜回风路60和冷却室40内可能还残留有部分热气。因此,可通过打开排放风门51导通排放风路50,使蒸发器41循环除霜结束后残留的热气通过排放风路50排放至环境空间,从而进一步避免了残留热气进入储物间室内引起温度拨动。
进一步地,排放风路50与除霜回风路60连通的一端在空气流动方向上位于除霜回风风门61的上游。由此,在蒸发器41循环除霜结束后,位于除 霜回风路60中的除霜回风风门61关闭以阻断除霜回风路60的同时,并不影响排放风路50的导通。也就是说,除霜回风风门61可将除霜回风路60分为在空气流动方向上的上游部分和下游部分,排放风路50与除霜回风路60连通的一端位于除霜回风路60的上游部分,从而使得除霜回风风门61关闭时,其上游部分还能与排放风路50连通。
在本发明的一些实施例中,除霜回风路60与冷却室40连通的一端在空气流动方向上位于风机42的下游。由此,当蒸发器41需要除霜时,可使风机42以较低功率继续工作,以驱动除霜时产生的热气通过位于风机42下游的除霜回风路60返回至冷却室40的底部,而不需要额外的驱动部件,简化了冷冻冷藏装置1的结构。
在本发明的一些实施例中,如图1所述,本发明的冷冻冷藏装置1中,至少一个储物间室包括冷冻间室12。供给风路包括开设在冷冻间室12后盖板121上的冷冻进风口212;返回风路包括位于冷冻间室12底部的冷冻回风道32。供给风门包括设置在冷冻进风口212处的冷冻进风风门222。也就是说,冷却室40通过冷冻进风口212与冷冻间室12连通。
具体地,冷却室40通过其送气开口部向冷冻间室12供应冷却气流。在该实施例中,送气开口部可包括与冷冻进风口212连通的冷冻送气开口。冷冻送气开口在空气流动方向上位于蒸发器41的下游,以供经蒸发器41冷却后的空气通过其中。冷却室40的返气开口部包括与冷冻回风道32连通的冷冻返气开口。冷冻返气开口在空气流动方向上位于蒸发器41的上游,以将来自冷冻间室12内的空气引导至蒸发器41,以便于冷却。
在本发明的一些实施例中,蒸发器41的顶部设有第一温度传感器411,以检测蒸发器41顶部的温度。当蒸发器41顶部达到第一预定的温度后,可判断蒸发器41除霜结束,因此可通过第一温度传感器411检测的温度数据自动控制除霜加热器43停止对蒸发器41进行加热,以实现智能化控制。
进一步地,冷冻间室12的后盖板上可设置第三温度传感器122,以检测冷冻间室12内的温度。
在本发明的一些实施例中,除霜加热器43可设置在蒸发器41的底部,且与位于冷却室40底部的凹槽44相对,以使除霜时产生的化霜水通过与凹槽44连通的排水管70流入位于箱体100底部的接水盒80中。接水盒80设置在压缩机90之上,在压缩机90工作运行时,通过其产生的热量将接水盒 80中的水分蒸发掉。
图2是根据本发明一个实施例的冷冻冷藏装置处于制冷状态的示意性结构图,图中箭头表示空气的流动方向。冷冻冷藏装置1处于制冷状态下,压缩机90、蒸发器41和风机42均处于开启状态。冷冻进风风门222打开,以导通冷冻进风口212。经过蒸发器41冷却的气流依次通过冷却室40的冷冻送气开口部、冷冻进风风门222和冷冻进风口212路流入冷冻间室12。冷冻间室12内的空气通过冷冻回风道32返回至冷却室40的返气开口部,经蒸发器41冷却后再次流入冷冻间室12,由此形成了冷冻间室12的空气循环路径。并且,除霜回风风门61关闭,以阻断除霜回风路60;排放风门51关闭,以阻断排放风路50,防止经过蒸发器41冷却的冷却气流流至环境空间。
进一步地,当第三温度传感器122检测到冷冻间室12内的温度达到第三预定值时,冷冻冷藏装置1可控制冷冻进风风门222关闭。从而实现了储物间室制冷的自动控制。
图3是根据本发明一个实施例的冷冻冷藏装置处于循环除霜状态的示意性结构图,图中箭头所示为空气的流动方向。冷冻冷藏装置1处于循环除霜状态时,压缩机90和蒸发器41均处于停止状态,风机42以较低功率工作。除霜加热器43启动,对蒸发器41进行加热。除霜回风风门61打开,以使除霜加热器43对蒸发器41进行加热除霜时产生的热气通过除霜回风道60返回至位于冷却室40内的蒸发器41的底部,从而再次利用该热气对蒸发器41进行循环除霜。同时,排放风门51处于关闭的状态,防止该热气直接排放至环境空间。且冷冻进风风门222关闭,以阻断冷冻进风口212,防止除霜产生的热气进入冷冻间室12,避免其产生温度波动影响食物的储藏。
图4是根据本发明一个实施例的冷冻冷藏装置处于排气状态的示意性结构图,图中箭头所示为空气的流动方向。如图4所示,当蒸发器41除霜结束后,冷却室40及除霜回风道60内可能还残留有部分热气,此时可继续保持冷冻进风风门222为关闭状态,同时关闭除霜回风风门61,打开排放风路50中的排放风门51,以使残留热气通过排放风路50直接排放至环境空间。环境空间中的空气可依次通过接水盒80、排水管70和凹槽44进入冷却室40内,以形成冷冻冷藏装置排气时的空气循环路径。进一步地,冷冻冷藏装置1处于排气状态时,风机42可处于停止状态,循环除霜残留的 热气可通过自然散热的方式经排放风路50排放至环境空间。优选地,风机42还可处于以较低功率工作的状态,以通过强制方式促使残留的热气经排放风路50排放至环境空间。
可见,本发明的冷冻冷藏装置1可充分有效地利用除霜加热器43对蒸发器41加热除霜时产生的热气,并且能够将除霜结束后残留的热气排放至环境空间,因此,蒸发器41除霜操作对冷冻间室内的温度影响较小,蒸发器41除霜结束后,再次对冷冻间室进行制冷时,可在较短时间内使储物间室内的温度恢复至除霜之前的温度,从而降低了冷冻冷藏装置1的能耗。
图5根据本发明另一个实施例的冷冻冷藏装置的示意性结构图。如图5所示,在本发明的另一些实施例中,至少一个储物间室包括上下设置的冷藏间室11和冷冻间室12,冷却室40位于冷冻间室12的后面,并通过冷冻间室12的后盖板121与冷冻间室12相隔。供给风路包括位于冷藏间室11后方的冷藏进风道211和开设在冷冻间室12后盖板121上的冷冻进风口212。供给风门包括设置在冷藏进风道211内的冷藏进风风门221和设置在冷冻进风口212处的冷冻进风风门222。也就是说,本发明实施例中,冷却室40分别通过冷藏进风道211和冷冻进风口212与冷藏间室11和冷冻间室12连通。
进一步地,冷却室40具有与供给风路连通的送气开口部,以通过送气开口部向至少一个储物间室供给冷却气流。具体地,送气开口部可包括与冷藏进风道211的空气入口端连通的冷藏送气开口和与冷冻进风口212连通的冷冻送气开口。冷藏送气开口和冷冻送气开口在空气的流动方向上位于蒸发器41的下游,以供经蒸发器41冷却后的空气通过其中。进一步地,冷藏进风风门221可设置在冷藏进风风道211的空气入口端。本领域技术人员应理解,在本发明其他的实施方式中,冷藏进风风门221还可设置于冷藏进风道211的任意位置或设置在冷藏间室11的进风口处。
在本发明的一些实施例中,返回风路可包括冷藏回风道31和冷冻回风道32。冷却室40的返气开口部可包括与冷藏回风道31连通的冷藏返气开口和与冷冻回风道32连通的冷冻返气开口。返气开口部在空气流动方向上位于蒸发器41的上游,即冷藏返气开口和冷冻返气开口均位于蒸发器41的上游,以将来自冷藏间室11和冷冻间室12内的空气引导至蒸发器41,以便于冷却。冷藏回风道31由冷藏间室11的底部延伸至冷却室40的返气开 口部。
进一步地,冷藏间室11和冷冻间室12的后盖板上可分别设有第二温度传感器111和第三温度传感器122,以分别检测冷藏间室11和冷冻间室12内的温度。
本发明的另一些实施例中涉及的冷冻冷藏装置的其他结构特征与图1所示实施例箱体,这里不再赘述。
图6是根据本发明一个实施例的冷冻冷藏装置的除霜控制方法的流程图。在本发明实施例中,除霜控制方法包括:
步骤A:接受用于指示对位于冷冻冷藏装置1的冷却室40内的蒸发器41进行除霜的除霜信号;
步骤B:启动位于蒸发器41上的除霜加热器43;
步骤C:关闭位于冷冻冷藏装置1的供给风路中的供给风门,以阻断供给风路;以及
步骤D:打开位于冷冻冷藏装置1的除霜回风路60中的除霜回风风门61,以导通除霜回风路60,使得除霜加热器43除霜时产生的热气依次通过冷却室40的送气开口部、除霜回风路60和冷却室40的返气开口部返回至蒸发器41,以利用热气对蒸发器41进行循环除霜。
本领域技术人员应理解,在本发明实施例中,步骤C和步骤D没有先后顺序,即在启动除霜加热器43后,可先关闭供给风门,后打开除霜回风风门61;也可以先打开除霜回风风门61,后关闭供给风门。本发明实施例优选先关闭供给风门,后打开除霜回风风门61。
图7是根据本发明另一个实施例的冷冻冷藏装置的除霜控制方法的流程图。在本发明另一些实施例中,在步骤D之后还可包括:
步骤E:当蒸发器41顶部的温度达到第一预定温度后,停止除霜加热器43。在该步骤中,可通过设置在蒸发器41顶部的第一温度传感器411检测蒸发器41顶部的温度。第一预定温度可以为表示蒸发器41除霜结束的温度。
进一步地,在本发明的一些实施例中,在步骤E之后还包括:
步骤F:关闭除霜回风风门61,以阻断除霜回风路60;
步骤G:打开位于冷冻冷藏装置1的排放风路50中的排放风门51,以导通排放风路50,使得循环除霜产生的残留热气经由排放风路50直接排放 至环境空间。由此,避免循环除霜残留的热气进入储物间室内引起温度波动。
进一步地,在步骤G之后还包括:
步骤H:当除霜加热器43停止预定时间后,关闭排放风门51,以阻断排放风路50。即当除霜加热器停止43预定时间后,其加热蒸发器41除霜时残留的热气基本上已经全部排放至环境空间,此时关闭排放风门51可避免冷冻冷藏装置内的空气过多地与环境空间的空气发生热交换,影响冷冻冷藏装置的制冷性能。
本领域技术人员应理解,本发明涉及的冷冻冷藏装置1可以为冰箱、冰柜、酒柜、冷藏罐等具有冷藏或冷冻功能的装置,或具有冷藏或冷冻间室的其他装置。
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。
