- the method further includes step 111 , step 112 and step 113 .
- step 111 the controller 90 acquires an ice making stop instruction.
- step 111 the controller 90 controls the water injection device 100 to continue injecting water until the water injection time is equal to the first preset time T1 , and the controller 90 executes step 104 and step 112 in sequence.

- the controller 90 When the controller 90 reacquires the ice-making start instruction, the controller 90 first controls the ice maker 60 to make ice (that is, step 105), or, the controller 90 first executes step 110, and executes the ice-making step after step 110 105 (as shown in FIG. 36 ), thereby refreezing the water that has been poured into the ice-making tray 430 into ice.

如图4所示,制冷循环***20包括压缩机21、冷凝器22、切换阀组23和蒸发器24。制冷剂以压缩机21、冷凝器22、切换阀组23、蒸发器24、压缩机21的顺序循环来对腔室40制冷。当压缩机21启动时,制冷剂在由压缩机21压缩并排出后经过冷凝器22冷却,通过切换阀组23能够使制冷剂流向蒸发器24或流向制冰机60。流向蒸发器24的制冷剂,通过膨胀进行热量交换,从而可以对腔室40进行制冷。
在一些实施例中,蒸发器24包括冷冻蒸发器242。冷冻蒸发器242设于冷冻腔室402内,以直接对冷冻腔室402制冷。
在一些实施例中,如图6所示,蒸发器24包括冷藏蒸发器241和冷冻蒸发器242。冷藏蒸发器241设于冷藏腔室401内,以直接对冷藏腔室401制冷,冷冻蒸发器242的设置位置以及作用与前述相同,这里不再赘述。当然,本公开并不限于此,在一些实施例中,蒸发器24包括冷冻蒸发器242和变温蒸发器243。变温蒸发器243设于变温腔室404内,以直接对变温腔室404制冷,冷冻蒸发器242的设置位置以及作用与前述相同,这里不再赘述。
在一些实施例中,冰箱1还包括风扇25,风扇25位于冷藏腔室401、变温腔室404以及冷冻腔室402中的至少一个。控制器90与风扇25电连接,以控制风扇25的启动或停止。
需要说明的是,在一个腔室(即冷藏腔室401或变温腔室404)未设置有对应的蒸发器的情况下,具有对应蒸发器的腔室还设有风扇25,并且两个腔室之间设有风道。所述风道设有风门,所述风门由控制器90控制开启或关闭,以打开或关闭所述风道。
这样,风扇25可以将蒸发器(例如,冷冻蒸发器242)的冷量通过所述风道输送到未设置蒸发器的腔室内,以对该腔室制冷。当未设置蒸发器的腔室的温度达到预设温度时,控制器90控制所述风门关闭所述风道。此外,通过控制器90控制风扇25的启动或停止,使得各腔室之间进行冷量循环,以使各腔室的温度均衡。
例如,如图7所示,冷冻蒸发器242被配置为对变温腔室404制冷,以维持变温腔室404内的温度不超过第一预设温度。在此情况下,冷冻腔室402设有风扇25,冷冻腔室402和变温腔室404之间设有风道。风扇25将冷冻腔室402中的冷冻蒸发器242的冷量通过所述风道输送至变温腔室404,以保证变温腔室404的保鲜温度。
需要说明的是,所述第一预设温度高于变温腔室404的开机制冷预设温度。例如,变温腔室404的所述开机制冷预设温度为4℃,所述第一预设温度可以为5℃。
在一些实施例中,控制器90可以为设置在箱体10上的操控面板,也可以是移动控制终端,例如手机或遥控器。
控制器90包括处理器。处理器可以包括中央处理器(central processing unit,CPU))、 微处理器(microprocessor)、专用集成电路(application specific integrated circuit,ASIC),并且可以被配置为当处理器执行存储在耦合到控制器90的非暂时性计算机可读介质中的程序时,执行控制器90中描述的相应操作。非暂时性计算机可读存储介质可以包括磁存储设备(例如,硬盘、软盘、或磁带)、智能卡、或闪存设备(例如,可擦除可编程只读存储器(erasable programmable read-only memory,EPROM)、卡、棒、或键盘驱动器)。
在一些实施例中,冰箱1还包括注水装置100。控制器90与注水装置100电连接以控制注水装置100为制冰机60注水。
例如,如图5所示,注水装置100包括进水管930和水阀,控制器90控制所述水阀开启或关闭以控制进水管930对制冰机60注水。进水管930设置在制冰腔室403的顶部。进水管930的出水口与制冰机60的注水口411相对应,以便于将外界的水注入制冰机60内。由于制冰机60安装在制冰腔室403的顶部,进水管930也安装在制冰腔室403的顶部,因此缩短了进水管930的长度,减少了进水管930占用的空间。
下面详细描述根据本公开一些实施例的制冷循环***20。
在一些实施例中,如图7所示,压缩机21和冷凝器22构成制冷剂运输流路100,制冷循环***20包括制冷剂运输流路100、冷藏制冷流路200以及制冰制冷流路300。制冷剂运输流路100、冷藏制冷流路200以及制冰制冷流路300均设置在箱体10内。制冷剂运输流路100包括制冷剂排出端A和制冷剂回流端B。压缩机21和冷凝器22在制冷剂运输流路100中沿制冷剂的流动方向依次排布。
冷藏制冷流路200被配置为对冷藏腔室401制冷。冷藏制冷流路200的一端与制冷剂排出端A相连,冷藏制冷流路200的另一端与制冷剂回流端B相连。
冷藏制冷流路200包括冷藏节流装置210和冷藏蒸发器241,冷藏节流装置210和冷藏蒸发器241在冷藏制冷流路200中沿制冷剂的流动方向依次排布。
例如,冷藏蒸发器241具有制冷剂入口端和制冷剂出口端。冷藏节流装置210的上游侧设有切换阀组23。冷藏节流装置210的一端与制冷剂排出端A相连,且冷藏节流装置210的另一端与冷藏蒸发器241的所述制冷剂入口端相连。冷藏蒸发器241的所述制冷剂出口端与制冷剂回流端B相连。
制冰制冷流路300被配置为对制冰机60制冷。制冰制冷流路300的一端与制冷剂排出端A相连,且制冰制冷流路300的另一端与制冷剂回流端B相连。
制冰制冷流路300包括制冰节流装置310,且制冰制冷流路300上设有制冰机60。制冰节流装置310和制冰机60在制冰制冷流路300中沿制冷剂的流动方向依次排布。
例如,制冰机60具有制冷剂入口端和制冷剂出口端。制冰节流装置310的上游侧设有切换阀组23。制冰节流装置310的一端与制冷剂排出端A相连,且制冰节流装置310的另一端与制冰机60的所述制冷剂入口端相连。制冰机60的所述制冷剂出口端与制冷剂回流端B相连。
切换阀组23与制冷剂排出端A相连,且切换阀组23设置在冷藏制冷流路200和制冰制冷流路300的上游侧。切换阀组23与控制器90电连接,切换阀组23可以在控制器90的控制下切换制冷流路。在一些实施例中,切换阀组23为电动阀。
在一些实施例中,切换阀组23能够在第一位置P1和第二位置P2之间切换。当切换阀组23处于第一位置P1时,冷藏制冷流路200与制冷剂运输流路100相连通,且制冰制冷流路300与制冷剂运输流路100断开。
当切换阀组23处于第二位置P2时,制冰制冷流路300与制冷剂运输流路100相连通,且冷藏制冷流路200与制冷剂运输流路100断开。
当制冰机60制冰时,控制器90控制制冰机60启动,并控制切换阀组23处于第二位置P2,以使制冰制冷流路300和制冷剂运输流路100连通,并使冷藏制冷流路200和制冷剂运输流路100断开。当控制器90控制制冰机60中的加热器件(例如,加热管)和翻冰机构(例如,翻冰杆)进行刮冰时,控制器90控制切换阀组23处于第一位置P1,以使制冰制冷流路300和制冷剂运输流路100断开,并使冷藏制冷流路200和制冷剂运输流路100 连通。
当制冰机60不需要制冷时,控制器90控制切换阀组23处于第一位置P1,以使冷藏制冷流路200与制冷剂运输流路100连通,并使制冰制冷流路300和制冷剂运输流路100断开。
需要说明的是,制冰机60不需要制冷的情况包括制冰机60进行刮冰的情况和制冰机60没有制冰需求的情况。在制成冰块后,制冰机60需要进行刮冰。制冰机60的刮冰过程包括加热、翻冰、排水等过程。在制成冰块后,控制器90控制制冰机60中的所述加热器件对制冰机60的制冰格加热,以使所述制冰格中的冰块略微融化并与所述制冰格分离。然后,控制器90控制制冰机60中的所述翻冰机构将冰块从所述制冰格中翻出。在翻冰结束后,制冰机60进行排水。
当冷藏腔室401的温度降低至第二预设温度、且制冰机60需要制冷时,控制器90控制切换阀组23处于第二位置P2,以使制冰制冷流路300和制冷剂运输流路100连通,并且冷藏制冷流路200和制冷剂运输流路100断开。
当冷藏腔室401的温度未降低至所述第二预设温度、且制冰机60需要制冷时,优先对冷藏腔室401制冷,控制器90控制切换阀组23处于第一位置P1,以使冷藏制冷流路200与制冷剂运输流路100连通。当冷藏腔室401的温度降低至所述第二预设温度之后,控制器90控制切换阀组23处于第二位置P2,以使制冰制冷流路300和制冷剂运输流路100连通。
需要说明的是,所述第二预设温度低于冷藏腔室401的停机制冷预设温度。例如,冷藏腔室401的所述停机制冷预设温度为-1℃,所述第二预设温度可以为-2℃。
根据本公开一些实施例的冰箱1,利用制冰机60的刮冰时间对冷藏腔室401制冷。因此,在刮冰过程中,压缩机21无需停止,解决了压缩机21需要在刮冰结束后才能再次启动的问题,避免了压缩机21的频繁启动和关闭,利于延长压缩机21的使用寿命。
并且,在制冰过程中,制冷剂运输流路100与冷藏制冷流路200断开,从而不干扰制冰机60的制冰过程,增加了流经制冰机60的制冷剂的量,使得制冰机60可以保持低温进行制冰,利于提高制冰机60的工作效率。
此外,由于在制冰过程中制冷剂运输流路100与冷藏制冷流路200断开,而在刮冰的过程中使制冷剂运输流路100与冷藏制冷流路200连通,因此可以利用刮冰的时间将冷藏腔室401的温度降低至所述第二预设温度,从而可以使制冷剂主要供应于制冷机60制冰。
通过实验验证,如图8所示,本公开实施例中冰箱1的制冷循环周期可以降低至40min,相较于通常冰箱的60min的制冷循环周期而言,缩短了制冰循环周期,利于提高制冰机60的制冰效率。
在一些实施例中,如图7所示,制冷循环***20还包括冷冻制冷流路500。冷冻制冷流路500被配置为对冷冻腔室402进行制冷。冷冻制冷流路500的一端与制冷剂排出端A相连,且冷冻制冷流路500的另一端与制冷剂回流端B相连。
切换阀组23设置在冷冻制冷流路500的上游侧,切换阀组23可以在控制器90的控制下使冷冻制冷流路500和制冷剂运输流路100连通或断开。这样,通过切换阀组23能够控制冷冻制冷流路500和制冷剂运输流路100的连通或断开,便于控制制冷剂的分布。
冷冻制冷流路500包括冷冻节流装置510和冷冻蒸发器242,冷冻节流装置510和冷冻蒸发器242在冷冻制冷流路500中沿制冷剂的流动方向依次排布。
例如,冷冻蒸发器242具有制冷剂入口端和制冷剂出口端。冷冻节流装置510的一端与制冷剂排出端A相连,且冷冻节流装置510的另一端与冷冻蒸发器242的所述制冷剂入口端相连。冷冻蒸发器242的所述制冷剂出口端与制冷剂回流端B相连。通过设置冷冻节流装置510和冷冻蒸发器242使制冷剂的形态发生转换,便于实现对冷冻腔室402的制冷。
在一些实施例中,如图7所示,冷冻蒸发器242位于冷藏蒸发器241与制冷剂回流端B之间。例如,冷藏蒸发器241的所述制冷剂出口端与冷冻蒸发器242的所述制冷剂入口端相连。这样,使得经由冷藏蒸发器241的制冷剂在与冷藏腔室401进行热量交换后,还 能够流入冷冻蒸发器242内以进行热量交换,提高制冷剂的利用效率。
在一些实施例中,如图7所示,冷冻蒸发器242位于制冰机60的所述制冷剂出口端与制冷剂回流端B之间。例如,制冰机60的所述制冷剂出口端与冷冻蒸发器242的所述制冷剂入口端相连。这样,使得经由制冰机60的制冷剂在与制冰机60进行热量交换后,还能够流入冷冻蒸发器242内以进行热量交换,从而提高制冷剂的利用效率。
在一些实施例中,各制冷流路的节流装置均为减压器,例如,毛细管。所述毛细管具有节流降压和调节流量的作用,并且还具有防止湿压缩和液击以及过热的功能。
需要说明的是,湿压缩是指压缩机21吸入的气态制冷剂中夹杂有液态制冷剂,从而影响压缩机21的正常工作。液击是指在压缩机21吸入夹杂有液态制冷剂的气态制冷剂后,压缩机21中的气缸异常冲击的情形。
通常,毛细管是一根细而长的紫铜管。毛细管的内径一般为0.5mm-1mm之间的任一值(例如,0.5mm、0.65mm、0.75mm、0.85mm或1mm),长度为2m-4m之间的任一值(例如,2m、2.5m、3m、3.5m或4m)。铜管的导热性能好。由于毛细管的内径较小,只能通过一定量的高压液体,因此,制冷剂在从所述毛细管进入蒸发器24后,制冷剂的压力降低,从而制冷剂会吸收热量,并从液态变成气态,以此实现制冷。
并且,压缩机21在将制冷剂输送至冷凝器22后由于有所述毛细管的阻碍,制冷剂在冷凝器22内保持高压状态,从而制冷剂可从气态冷却成液态。此外,所述毛细管通过调节制冷剂流量还可以调节蒸发器24内的蒸发温度。
控制器90按制冷优先级进行制冷流路的选择,通过控制制冰机60、蒸发器24以及各腔室的风扇25的启停,满足各腔室按需制冷的要求。
以上主要结合图7描述了冷藏制冷流路200与制冰制冷流路300的制冰机60并联的实施例(即冷藏制冷流路200中的冷藏蒸发器241的所述制冷剂出口端与制冰机60的所述制冷剂入口端断开),但本公开并不限于此。
在一些实施例中,如图9所示,冷藏制冷流路200与制冰制冷流路300中的制冰机60串联(即冷藏制冷流路200中的冷藏蒸发器241的所述制冷剂出口端与制冰机60的所述制冷剂入口端相连)。
在此情况下,当需要制冰时,控制器90控制压缩机21、冷凝器22以及制冰机60启动,且控制切换阀组23处于第一位置P1,使冷藏制冷流路200和制冷剂运输流路100连通,以对冷藏腔室401进行制冷。当冷藏腔室401的温度降低至所述第二预设温度时,控制器90控制切换阀组23处于第二位置P2,使冷藏制冷流路200和制冷剂运输流路100断开,并使制冰制冷流路300和制冷剂运输流路100连通,以进行制冰。
在一些实施例中,如图9所示,制冷循环***20包括三种制冷剂运行轨迹。
第一种制冷剂的运行轨迹包括:压缩机21→冷凝器22→切换阀组23→冷藏节流装置210→冷藏蒸发器241→制冰机60→冷冻蒸发器242→压缩机21。冷藏蒸发器241与制冰机60以及冷冻蒸发器242串联,以进行制冷,从而可对制冷循环***20中的相应器件(例如,冷藏蒸发器241、制冰机60或冷冻蒸发器242等)制冷。该轨迹能够实现冷藏腔室401的制冷。
第二种制冷剂的运行轨迹包括:压缩机21→冷凝器22→切换阀组23→制冰节流装置310→制冰机60→冷冻蒸发器242→压缩机21。该轨迹利于提高制冰机60的制冰效率,并且还可对冷冻腔室402进行制冷。
第三种制冷剂的运行轨迹包括:压缩机21→冷凝器22→切换阀组23→冷冻节流装置510→冷冻蒸发器242→压缩机21。该轨迹可对冷冻腔室402以及变温腔室404进行制冷。当冷冻腔室402需要制冷而制冰机60不需要制冷或者制冰机60为关闭状态时,制冷剂按照该轨迹流动。
由此可见,上述第一种制冷剂的运行轨迹和第二种制冷剂的运行轨迹可以实现制冰机60制冷,通过控制切换阀组23所处的状态,可以提高制冰机60的工作效率。
在一些实施例中,当冷藏腔室401的温度大于或等于第三预设温度时,控制器90控 制切换阀组23处于第一位置P1,使冷藏制冷流路200和制冷剂运输流路100连通,从而防止因冷藏腔室401的温度过高而导致冷藏腔室401内存放的物品变质。
需要说明的是,所述第三预设温度高于冷藏腔室401的开机制冷预设温度。例如,冷藏腔室401的所述开机制冷预设温度为1℃,所述第三预设温度可以为2℃。
在一些实施例中,制冰机60包括至少两个独立设置的制冷剂管400(见图5)。冷藏制冷流路200和制冰制冷流路300分别连接一个制冷剂管400的入口端,制冷剂管400的出口端与制冷剂回流端B相连,从而制冰机60可以分别与冷藏制冷流路200以及制冰制冷流路300连通,此时,无需设置切换阀组23,简化了冰箱1的结构。
根据本公开一些实施例的冰箱1,冰箱1在开始制冰时,优先满足冷藏腔室401的制冷需求。当冷藏腔室401的温度降低至所述第二预设温度时,控制器90控制切换阀组23使冷藏制冷流路200与制冷剂运输流路100断开,并使制冰制冷流路300与制冷剂运输流路100连通,以对制冰机60进行制冰。
这样,在制冰机60的制冰过程中,无需给冷藏腔室401制冷,从而不会干扰制冰机60的制冰过程,并且制冷剂主要供应于制冰制冷流路300,使得制冰机60可以保持低温进行制冰,利于提高制冰效率。
需要说明的是,在完成对冷藏腔室401的制冷后,从冷藏制冷流路200流入制冰机60的制冷剂的温度低于制冰机60的温度,因此制冷剂能够对制冰机60制冷。
由于在制冰机60的制冰过程中,大约40min无需对冷藏腔室401进行制冷,即大约40min制冷剂无需流经冷藏制冷流路200,因此,制冷剂主要供应于制冰制冷流路300,从而可对制冰机60进行连续制冷。
在制成冰块后,制冰机60进行刮冰,此时,若各制冷流路没有制冷需求,则压缩机21也会关闭。在刮冰结束后,一个制冰周期结束,压缩机21重新启动,首先对冷藏腔室401进行制冷。当冷藏腔室401的温度达到大约第二预设温度(例如-1℃或0℃)时,停止对冷藏腔室401制冷以使冷藏腔室401的温度自然回升,直到下次制冰结束且压缩机21再次启动时再重新对冷藏腔室401进行制冷,利于提高制冰效率。
上述主要结合图7和图9描述了制冰机60与冷冻制冷流路500中的冷冻蒸发器242为串联关系,且制冰机60位于冷冻制冷流路500中的冷冻蒸发器242的上游侧的实施例。但本公开并不限于此。
在一些实施例中,如图10所示,冷冻制冷流路500中的冷冻蒸发器242与制冰机60串联,且制冰机60位于冷冻制冷流路500中的冷冻蒸发器242的下游侧。
在此情况下,制冰机60包括两个独立的制冷剂管400。两个制冷剂管400的出口端均与制冷剂回流端B相连。一个制冷剂管400的入口端与冷冻制冷流路500的所述另一端(即冷冻蒸发器242的所述制冷剂出口端)相连,另一个制冷剂管400的入口端与制冰制冷流路300中的制冰节流装置310的所述另一端相连。制冰制冷流路300和冷冻制冷流路500中的任一个均可对制冰机60制冷。
在一些实施例中,如图11所示,冷藏制冷流路200的所述一端与切换阀组23相连,且冷藏制冷流路200的所述另一端与冷冻制冷流路500的第一节点C相连。
需要说明的是,第一节点C位于冷冻节流装置510和冷冻蒸发器242之间。例如,第一节点C位于冷冻蒸发器242的所述制冷剂入口端。
这样,通过将冷藏制冷流路200的所述另一端连接在冷冻节流装置510和冷冻蒸发器242之间,使得制冷剂运输流路100在对冷冻制冷流路500供应制冷剂以制冷冷冻腔室402的情况下还能够对冷藏制冷流路200供应制冷剂以制冷冷藏腔室401。
在此情况下,冷冻腔室402设有风扇25,变温腔室404与冷冻腔室402之间具有风道,所述风道设有风门。变温腔室404与冷冻腔室402通过风扇25和所述风道进行冷量循环,并由控制器90控制所述风门开启或闭合以打开或关闭所述风道。控制器90控制风扇25将冷冻蒸发器242的冷量通过所述风道输送至变温腔室404,对变温腔室404制冷以保证变温腔室404的温度,从而通过冷冻蒸发器242对冷冻腔室402和变温腔室404制冷。
在一些实施例中,如图12所示,制冷循环***20还包括变温制冷流路600。变温制冷流路600被配置为对变温腔室404进行制冷。变温制冷流路600的上游侧设有切换阀组23。变温制冷流路600的一端与制冷剂排出端A相连,并且变温制冷流路600的另一端与冷冻制冷流路500的第一节点C相连。
这样,通过制冷剂运输流路100不仅可以对冷冻制冷流路500供应制冷剂以制冷冷冻腔室402,还能够对变温制冷流路600供应制冷剂以对变温腔室404制冷。
变温制冷流路600包括变温节流装置610和变温蒸发器243,变温节流装置610和变温蒸发器243在变温制冷流路600中沿制冷剂的流动方向依次排布。
在此情况下,冷冻蒸发器242被配置为维持冷藏腔室401的温度不超过所述第三预设温度。
例如,如图12所示,冷冻腔室402设有风扇25,冷藏腔室401与冷冻腔室402之间具有风道,所述风道设有风门。冷藏腔室401与冷冻腔室402通过风扇25和风道进行冷量循环,并由控制器90控制所述风门开启或闭合以打开或关闭所述风道。控制器90控制风扇25将冷冻蒸发器242的冷量通过所述风道输送至冷藏腔室401,对冷藏腔室401制冷以保证冷藏腔室401的温度,从而制冷剂只需经过冷冻蒸发器242即可对该两个腔室制冷。
在一些实施例中,由于制冰机60包括两个制冷剂管400,因此制冷循环***20包括独立设置的两种制冷剂的运行轨迹,即第四种制冷剂的运行轨迹和第五种制冷剂的运行轨迹。
第四种制冷剂的运行轨迹包括:压缩机21→冷凝器22→切换阀组23→冷冻节流装置510→冷冻蒸发器242→制冰机60→压缩机21。在此情况下,相较于冷冻蒸发器242位于各制冷流路的下游侧并且被多个制冷流路供应制冷剂以进行制冷的方式,冷冻蒸发器242可单独占用一个制冷流路以对冷冻腔室402制冷。并且,冷冻蒸发器242不仅可以对冷冻腔室402进行制冷,还可以对冷藏腔室401或变温腔室404进行制冷。
在该轨迹中,制冷剂在从冷冻蒸发器242流出后,流入制冰机60的一个制冷剂管400,并在对制冰机60进行制冷后,返回至压缩机21中。从而在满足冰箱1的各腔室的制冷需求的同时还能制冰。
此外,当该轨迹中的制冷剂给制冰机60供冷时,制冷剂产生的冷量还可以冷却储冰盒70,更好地储存冰块。例如,制冰机60包括循环风扇,所述循环风扇将制冷剂管400周围的冷气输送到储冰盒70,从而保证储冰盒70的温度。
第五种制冷剂的运行轨迹包括:压缩机21→冷凝器22→切换阀组23→制冰节流装置310→制冰机60→压缩机21。制冷剂可沿该轨迹独立运行以满足制冰机60的制冷需求。
在一些实施例中,该两种制冷剂的运行轨迹并联组成制冷循环***20,控制器90控制切换阀组23选择性地导通或断开制冷流路,便于提高制冰效率。
并且,由于制冰机60可通过两种制冷流路中的任一个进行制冷,因此,在制冰的过程中,控制器90可以控制切换阀组23使冷冻制冷流路500与制冷剂运输流路100断开,使得在制冰机60的制冰过程中,冷冻腔室402不再被动制冷。冷冻腔室402的制冷过程不被其它制冷流路干扰,便于精确控制冷冻腔室402的温度,避免冷冻腔室402严重偏冷,且减少冷冻腔室402不必要的低温时间,缩短化霜时间,节约能耗。
此外,当冷冻蒸发器242需要化霜时,控制器90控制切换阀组23使制冷剂运输流路100与冷冻制冷流路500断开,并使制冷剂运输流路100与制冰制冷流路300连通。此时,冷冻蒸发器242停止工作而制冰机60仍可继续制冰,使得制冷循环***20无需停止工作,利于提高制冰机60的制冰效率。并且,当储冰盒70中储存的冰块较多时,可通过控制器90控制切换阀组23以选择性地断开或导通制冷流路,节约能源。
在一些实施例中,切换阀组23能够在第三位置P3、第四位置P4及第五位置P5之间切换。
当切换阀组23处于第三位置P3时,制冷剂运输流路100的制冷剂排出端A分别与冷冻制冷流路500和制冰制冷流路300连通。此时,制冷剂可沿上述两种制冷剂的运行轨迹 流动。
当切换阀组23处于第四位置P4时,制冷剂运输流路100的制冷剂排出端A与冷冻制冷流路500连通,且制冷剂运输流路100的制冷剂排出端A与制冰制冷流路300断开。此时,制冷剂沿上述第四种制冷剂的运行轨迹流动。
当切换阀组23处于第五位置P5时,制冷剂运输流路100的制冷剂排出端A与制冰制冷流路300连通,且制冷剂运输流路100的制冷剂排出端A与冷冻制冷流路500断开。此时,制冷剂沿上述第五种制冷剂的运行轨迹流动。
当冷冻制冷流路500中的冷冻蒸发器242需要化霜,且制冰机60有制冰需求时,控制器90控制切换阀组23处于第五位置P5,制冷剂运输流路100的制冷剂排出端A与制冰制冷流路300连通,且制冷剂运输流路100的制冷剂排出端A与冷冻制冷流路500断开。从而使冷冻蒸发器242化霜时,制冰机60能够继续制冰。
当冷冻制冷流路500中的冷冻蒸发器242无需化霜,且需求的冰块量大于或等于第一阈值、且小于或等于储冰盒70的最大储冰量时,控制器90控制切换阀组23处于第三位置P3,制冷剂运输流路100的制冷剂排出端A分别与冷冻制冷流路500和制冰制冷流路300连通,从而使制冰机60的制冰效率达到最高。
所述第一阈值为预先设定的阈值。例如,所述第一阈值为储冰盒70的最大储冰量的三分之二。
需要说明的是,上述最大储冰量可以是储冰盒70中存储的冰块的体积、数量或质量等。
当冷冻制冷流路500中的冷冻蒸发器242无需化霜,以及需求的冰块量大于或等于第二阈值、且小于所述第一阈值时,控制器90控制切换阀组23处于第五位置P5,制冷剂运输流路100的制冷剂排出端A与冷冻制冷流路500断开,且制冷剂运输流路100的制冷剂排出端A与制冰制冷流路300连通。
所述第二阈值为预先设定的阈值。例如,所述第二阈值为储冰盒70的最大储冰量的三分之一。
当冷冻制冷流路500中的冷冻蒸发器242无需化霜,且需求的冰块量小于所述第二阈值时,控制器90控制切换阀组23处于第四位置P4,制冷剂运输流路100的制冷剂排出端A与冷冻制冷流路500连通,且制冷剂运输流路100的制冷剂排出端A与制冰制冷流路300断开。从而满足制冰机60制冷的最低需求,保证储冰盒70的温度,且节约能源。
在一些实施例中,当冷冻腔室402的温度达到第四预设温度,且制冰机60有制冰需求时,控制器90控制切换阀组23处于第五位置P5,使制冷剂运输流路100的制冷剂排出端A与冷冻制冷流路500断开,且制冷剂运输流路100的制冷剂排出端A只与制冰制冷流路300连通,从而解决冷冻腔室402在制冰机60的制冰过程中被动制冷的问题。冷冻腔室402的制冷过程不被其它制冷流路干扰,便于精确控制冷冻腔室402的温度,避免冷冻腔室402严重偏冷,且减少冷冻腔室402不必要的低温时间,缩短化霜时间,节约能耗。
需要说明的是,所述第四预设温度低于冷冻腔室402的停机制冷预设温度。例如,冷冻腔室402的所述停机制冷预设温度为-1℃,所述第四预设温度可以为-2℃。
冰箱1在启动后,控制器90根据储冰盒70中的冰块量,对冰块的需求量进行判断。通常,需要保证储冰盒70中的冰块量不低于储冰盒70的最大储冰量的80%。当储冰盒70中的冰块量低于储冰盒70的最大储冰量的80%时,控制器90控制制冰机60启动以制冰。
在一些实施例中,冰箱1包括探冰杆或红外传感器中的至少一个。所述探冰杆或所述红外传感器被配置为检测储冰盒70中的冰块量,探冰杆或红外传感器中的至少一个与控制器90电连接,储冰盒70中的冰块量可通过所述探冰杆或所述红外传感器中的至少一个确定后反馈至控制器90。
例如,所述探冰杆位于储冰盒70的上方。控制器90通过控制所述探冰杆向下运动,使得所述探冰杆触碰到储冰盒70中的冰块。此时,所述探冰杆停止运动,控制器90通过读取所述探冰杆的移动距离或者所述探冰杆向下旋转的角度,判断此时储冰盒70中存储 的冰块量。
又例如,储冰盒70内设置有多对红外传感器。多对红外传感器沿着储冰盒70的高度方向依次排布。每一对红外传感器中的两个红外传感器沿水平方向相对设置,并且每一对红外传感器设置在对应储冰盒70不同的储冰量(例如,储冰盒70的最大储冰量的三分之一、储冰盒70的最大储冰量的三分之二或储冰盒70的最大储冰量)的位置处。当储冰盒70内的储冰量超过一对红外传感器的设置位置时,储冰盒70中的冰块能够阻挡一对红外传感器之间的红外线的传播。由于控制器90与红外传感器电连接,此时,控制器90能够检测到相应的信号,从而能够根据该信号确定对应的一对红外传感器所处的位置,从而进一步判断此时储冰盒70中对应的冰块量。
根据本公开一些实施例的冰箱1,由于冰箱1中的制冰机60包括两个独立的制冷剂管400,制冰机60可通过两种制冷剂的运行轨迹进行制冷,因此,在制冰过程中,可以通过控制器90控制切换阀组23使冷冻制冷流路500与制冷剂运输流路100断开,使得在制冰机60的制冰过程中,冷冻腔室402不再被动制冷。冷冻腔室402的制冷过程不被其它制冷流路干扰,便于精确控制冷冻腔室402的温度,避免冷冻腔室402严重偏冷,且减少冷冻腔室402不必要的低温时间,缩短化霜时间,节约能耗。
并且,当冷冻蒸发器242化霜时,制冰机60仍可继续制冰,使得制冷循环***20无需停止工作,利于提高制冰机60的制冰效率。此外,当储冰盒70中储存的冰块较多时,可通过控制器90控制切换阀组23以选择性地断开或导通制冷流路,节约能源。
前文主要描述了制冷循环***20包括一个压缩机21的实施例,但本公开并不限于此。
在一些实施例中,制冷循环***20也可以包括多个压缩机21,对应地,制冰机60包括多个独立设置的制冷剂管400。制冷剂管400与压缩机21一一对应设置。
在一些实施例中,如图13所示,制冷循环***20中的压缩机21包括第一压缩机211和第二压缩机212。制冷循环***20中的冷凝器22包括第一冷凝器221和第二冷凝器222。制冰制冷流路300包括第一子制冰制冷流路700和第二子制冰制冷流路800。并且。制冰机60包括两个独立设置的制冷剂管400。
在此情况下,如图13和图14所示,第一子制冰制冷流路700包括第一制冰节流装置710。第一压缩机211、第一冷凝器221、第一制冰节流装置710以及制冰机60的一个制冷剂管400在第一子制冰制冷流路700中沿制冷剂的流动方向依次排布。如图13和图15所示,第二子制冰制冷流路800包括第二制冰节流装置810。第二压缩机212、第二冷凝器222、第二制冰节流装置810以及制冰机60的另一个制冷剂管400在第二子制冰制冷流路800中沿制冷剂的流动方向依次排布。
如图13和图14所示,第一子制冰制冷流路700被配置为对制冰机60制冷。第一压缩机211的制冷剂出口端与第一冷凝器221的制冷剂入口端相连。第一制冰节流装置710的一端与第一冷凝器221的制冷剂出口端相连,且第一制冰节流装置710的另一端与制冰机60中一个制冷剂管400的入口端相连。该制冷剂管400的出口端与第一压缩机211的制冷剂入口端相连。
如图13和图15所示,第二子制冰制冷流路800被配置为对制冰机60制冷。第二压缩机212的制冷剂出口端与第二冷凝器222的制冷剂入口端相连。第二制冰节流装置810的一端与第二冷凝器222的制冷剂出口端相连,且第二制冰节流装置810的另一端与制冰机60中另一个制冷剂管400的入口端相连。所述另一个制冷剂管400的出口端与第二压缩机212的制冷剂入口端相连。
在一些实施例中,如图13所示,冷冻制冷流路500的所述一端(即冷冻节流装置510的所述制冷剂入口端)与第一冷凝器221的所述制冷剂出口端相连,且冷冻制冷流路500的所述另一端(即冷冻蒸发器242的所述制冷剂出口端)与第一压缩机211的所述制冷剂入口端相连。冷冻节流装置510的制冷剂入口端与第二节点D相连。
需要说明的是,第二节点D位于第一节流装置710和第一冷凝器221之间。通过在第一子制冰制冷流路700上并联冷冻制冷流路500,使流经第一子制冰制冷流路700的制冷 剂的一部分可以流入冷冻制冷流路500中,从而不仅可以对制冰机60制冷,还可以对冷冻腔室402制冷。
在一些实施例中,如图13所示,冷冻蒸发器242位于制冰机60和第一压缩机211之间。第一子制冰制冷流路700中的所述一个制冰剂管400的出口端与冷冻蒸发器242的制冷剂入口端相连。因此,经由制冰机60的制冷剂还能够流入冷冻蒸发器242内进行热量交换,以对冷冻腔室402进行制冷,从而提高制冷剂的利用效率。
在一些实施例中,如图13所示,第一冷凝器221和第二冷凝器222复用,即第一子制冰制冷流路700中的第一冷凝器221和第二子制冰制冷流路800中的第二冷凝器222可以为同一个冷凝器22。第一压缩机211的所述制冷剂出口端和第二压缩机212的所述制冷剂出口端均与冷凝器22的制冷剂入口端相连。由于将两个制冷流路中的冷凝器221、222复用为一个冷凝器21,便于布置制冷循环***20,减少了零部件的数量,成本降低,并且减少了制冷循环***20占用的空间。
在一些实施例中,如图13和图14所示,切换阀组23位于第一子制冰节流装置710和第二节点D之间。切换阀组23还被配置为连通或断开第一子制冰节流装置710和第一冷凝器221。当制冰机60不需要制冷时,可以通过控制器90控制切换阀组23使第一子制冰节流装置710所在的支路断开,以关闭第一子制冰制冷流路700,从而解决因关闭第一压缩机211而导致的冷冻制冷流路500不能进行制冷的问题。
在一些实施例中,如图13和图14所示,冷冻蒸发器242被配置为对冷藏腔室401制冷。冷冻蒸发器242对冷藏腔室401制冷的制冷方式与前述相同,在此不再赘述。
如图13和图14所示,冷冻制冷流路500的制冷剂的运行轨迹包括:第一压缩机211→冷凝器22→冷冻节流装置510→冷冻蒸发器242→第一压缩机211。在此情况下,由于切换阀组23使第一子制冰制冷流路700关闭,因此冷冻蒸发器242单独占用一个制冷流路以对冷冻腔室402制冷。并且,冷冻制冷流路500通过冷冻蒸发器242不仅可以对冷冻腔室402进行制冷,还可以对冷藏腔室401制冷。
第一子制冰制冷流路700的制冷剂的运行轨迹包括:第一压缩机211→冷凝器22→切换阀组23→第一节流装置710→制冰机60→冷冻蒸发器242→第一压缩机211。第一子制冰制冷流路700对制冰机60、冷冻腔室402以及冷藏腔室401制冷。制冷剂经由第一节流装置710进入制冰机60制冷后,流入冷冻蒸发器242,以对冷冻腔室402以及冷藏腔室401制冷。
第二子制冰制冷流路800的制冷剂的运行轨迹包括:第二压缩机212→冷凝器22→第二节流装置810→制冰机60→第二压缩机212。由于流经第二子制冰制冷流路800的制冷剂只对制冰机60制冷,因此,在制冷剂量一定的情况下,第二子制冰制冷流路800中制冰机60的制冰效率高于第一子制冰制冷流路700中制冰机60的制冰效率。
当需求的冰块量大于第三阈值,且小于或等于储冰盒70的最大储冰量时,控制器90控制第一子制冰制冷流路700和第二子制冰制冷流路800均开启,且控制冷冻制冷流路500关闭。
所述第三阈值为预先设定的阈值。例如,所述第三阈值为储冰盒70的最大储冰量的二分之一。
当需求的冰块量小于或等于所述第三阈值时,且冷冻腔室402需要制冷时,控制器90控制冷冻制冷流路500和第一子制冰制冷流路700均开启,且控制第二子制冰制冷流路800关闭。
当需求的冰块量小于或等于所述第三阈值时,且冷冻腔室402不需要制冷时,控制器90控制第二子制冰制冷流路800开启,且第一子制冰制冷流路700以及冷冻制冷流路500均断开。
当没有制冰需求时,控制器90控制切换阀组23使第一子制冰制冷流路700断开,并且使第二压缩机212关闭。此时,控制器90控制冷冻制冷流路500根据冷冻腔室402的温度进行启动或关闭。
根据本公开一些实施例的冰箱1,第一子制冰制冷流路700和第二子制冰制冷流路800上分别设有第一压缩机211和第二压缩机212。第一子制冰制冷流路700和第二子制冰制冷流路800的制冷剂均经过制冰机60,因此两个压缩机(211、212)可以分别为制冰机60提供制冷剂,或者共同为制冰机60提供制冷剂。
当制冰需求不高时(例如,储冰盒70内的冰块量小于或等于所述第三阈值时),可以选择第一子制冰制冷流路700和第二子制冰制冷流路800中的任意一种制冷流路为制冰机60提供制冷剂,以在满足制冰需求的情况下降低能耗,节约能源。
当制冰需求较高时(例如,储冰盒70内的冰块量大于所述第三阈值且小于或等于所述制冰机的最大储冰量时),第一子制冰制冷流路700和第二子制冰制冷流路800均可为制冰机60提供制冷剂,从而有效提高制冰机60的制冰效果。此外,即使两个压缩机(211、212)中的一个压缩机出现故障,制冰机60仍然可以正常工作,提高了制冰机60的制冰稳定性。
如图3和图16所示,本公开一些实施例提供了一种制冰机60。制冰机60包括制冷剂管400。制冷剂管400被配置为对制冷机60进行制冷。制冷剂管400的一端与制冷剂运输流路100的制冷机排出端A相连,制冷剂管400的另一端与制冷剂运输流路100的制冷剂回流端B相连。
在一些实施例中,如图3所示,制冷剂管400包括内伸段311和外延段312。内伸段311包括制冷剂管400的位于制冰腔室403内的管段,外延段312包括制冷剂管400的位于制冰腔室403外的管段,外延段312与制冷循环***20连通。
在一些实施例中,如图17所示,制冷剂管400包括配合部132,配合部132设在制冷剂管400的外侧。制冰腔室403具有与配合部132相匹配的限位部131,且限位部131设置在制冰腔室403的后腔壁1310上。例如,制冷剂管400被限位于配合部132内,配合部132被配置为***限位部131中,以使配合部132与限位部131固定。
如图17所示,制冰腔室403还包括加强扣133,加强扣133与后腔壁1310相连,配合部132位于加强扣133的前侧。通过加强扣133能够限制配合部132向后方的移动,利于提高制冷剂管400的固定效果。
如图16和图18所示,制冰机60还包括基座410、风机组件420、制冰格430、固定盘440、接水盘450、翻冰杆460、上盖板470和加热管480(如图22所示)。
在一些实施例中,如图3和图16所示,基座410可拆卸地安装于制冰腔室403内顶部。例如,基座410通过卡扣或螺钉结构与制冰腔室403相连。基座410包括注水口411,注水口411被配置为供外部进水管930向制冰格430注水。
在一些实施例中,如图16和图18所示,风机组件420设置在基座410的底部,且风机组件420位于基座410的前侧。风机组件420的后侧为吸风侧,风机组件420的前侧或下侧、左侧或右侧中的至少一侧为出风侧。
例如,图16、图18以及图19示出了风机组件420的前侧为出风侧,图21至图23示出了风机组件420的下侧为出风侧。当风机组件420的左侧或右侧为出风侧时,风机组件420的结构可以参照风机组件420的前侧或下侧为出风侧设置,此处不再赘述。风机组件420能够驱动制冰腔室403内的风循环。风机组件420与制冰机60集成,利于简化结构。
如图18和图23所示,风机组件420包括外壳体421、循环风扇422和控制单元423。外壳体421设置在基座410的前端底部,外壳体421包括第一子外壳体421A和第二子外壳体421B,第一子外壳体421A和第二子外壳体421B相连。例如,第一子外壳体421A和第二子外壳体421B可以通过卡扣连接或螺钉连接的方式相连。
如图23所示,外壳体421包括吸风孔4211。吸风孔4211设置在外壳体421的后侧。例如,吸风孔4211可以设置在第一子外壳体421A的后侧。如图18和图19所示,外壳体421还包括出风孔4212。出风孔4212位于外壳体421的前侧。例如,出风孔4212可以设置在第二子外壳体421B的前侧。或者,如图21和图23所示,出风孔4212可以设置在外壳体421的下侧。
如图18所示,循环风扇422设置在外壳体421内,且循环风扇422被配置为使外壳体421的后侧为吸风侧。控制单元423与循环风扇422电连接,控制单元423包括风扇控件,所述风扇控件被配置为控制循环风扇422的开启和关闭,从而控制循环风扇422工作。
在一些实施例中,如图16和图18所示,制冰格430位于外壳体421的后侧。例如,制冰格430位于循环风扇422的吸风侧。由此,使得风机组件420可直接吸入制冷剂管400处的冷风并将冷风吹向制冰腔室403内,从而改善风循环。
制冰格430采用高导热金属材料制成。例如,制冰格430可以为铝或铝合金等。参见图19,制冰格430还包括导热肋片431,导热肋片431设置在制冰格430的底部,以提高换热效率。
在一些实施例中,如图19所示,制冷剂管400的内伸段311与制冰格430的底部接触,由此,在制冰时可以将冷量直接传递到制冰格430,提高制冰效率。
在一些实施例中,参见图22和图25,制冷剂管400的内伸段311形成为U形,制冰格430的底部设有U形槽,以容纳内伸段311。
在一些实施例中,参见图22及图25,加热管480设置在制冰格430的底部,加热管480与控制单元423电连接。控制单元423还包括加热控件,所述加热控件被配置为控制加热管480的开启和关闭,从而在制冰完成后,控制加热管480对制冰格430进行加热,使冰块的底部融化,便于后续脱冰。
例如,加热管480呈U形,加热管480的U形开口方向与内伸段311的U形开口方向相反,内伸段311在参考面上的正投影位于加热管480在所述参考面上的正投影的内侧,所述参考面平行于水平面。在制冰机60的高度方向上,加热管480与内伸段311处于同一高度位置或者不同高度位置。例如,如图25所示,加热管480高于内伸段311设置。
在一些实施例中,如图18和图19所示,固定盘440与制冰格430的底部可拆卸地连接,以使内伸段311紧贴制冰格430的底部。此外,固定盘440的内壁面与制冰格430的底部之间的区域构成通风道,在制冰机60的前后方向上,所述通风道与吸风孔4211(如图23所示)的位置相对应,吸风口4211与所述通风道相连通。
在一些实施例中,如图19和图27所示,固定盘440可通过紧固件与制冰格430连接。例如,制冰格430包括第一锁紧件432,第一锁紧件432位于制冰格430的底部。固定盘440包括第二锁紧件443,第二锁紧件443位于固定盘440的底壁上。第二锁紧件443与第一锁紧件432相匹配。
例如,第一锁紧件432包括螺柱,第二锁紧件443包括螺钉,所述螺柱与所述螺钉相配合,以使制冰格430与固定盘440可拆卸地连接。
在一些实施例中,如图28和图29所示,固定盘440的远离风机组件420的一端可转动地与制冰格430连接。例如,制冰格430还包括第一轴件434,第一轴件434位于制冰格430的远离风机组件420的一端。固定盘440还包括第二轴件444,第二轴件444位于固定盘440远离风机组件420的一端。第二轴件444与第一轴件434相匹配。
例如,第一轴件434包括轴孔,第二轴件444包括转轴,所述轴孔和所述转轴相匹配,以使固定盘440绕所述转轴相对于制冰格430向下翻转,如图29所示。
此外,如图28所示,外壳体421还包括第一卡部426,第一卡部426设置在外壳体421靠近制冰格430的一侧。固定盘440还包括第二卡部445,第二卡部445设置在固定盘440的靠近外壳体421的一侧。第二卡部445与第一卡部426相匹配。
例如,第一卡部426包括卡槽,第二卡部445包括卡勾。在将固定盘440安装到制冰格430底部时,当固定盘440转动到位后,所述卡勾可以卡接在所述卡槽中,以将固定盘440固定于制冰格430的底部。
此外,如图27所示,固定盘440还包括第二锁紧件443,第二锁紧件443设置在固定盘440的内壁面。如图19所示,制冰格430还包括第一锁紧件432,第一锁紧件432设置在制冰格430的底部。通过第一锁紧件432与第二锁紧件433的配合,可以进一步提高固定盘440与制冰格430的连接可靠性。
在将固定盘440安装到制冰格430底部时,由于固定盘440的远离风机组件420的一端与制冰格430可旋转连接,相当于预装配,因此不需要安装人员进行现场定位,可有效简化安装人员的操作,降低安装难度,提高安装效率,且便于拆卸。
在一些实施例中,如图27所示,固定盘440还包括支撑组件442。支撑组件442设置在固定盘440的内壁面上,且支撑组件442被配置为将内伸段311顶紧。支撑组件442包括顶紧部4421和弹性部4422。顶紧部4421的底部与固定盘440的底壁相连,顶紧部4421的顶部与弹性部4422相连。弹性部4422被配置为与内伸段311接触。
例如,弹性部4422的一侧(例如图27中的M侧)通过螺钉与顶紧部4421连接,且弹性部4422的另一侧设有半圆形的托槽4423,托槽4423被配置为承托内伸段311。
在一些实施例中,固定盘440或顶紧部4421中的至少一个包括高导热率金属材料件。例如,固定盘440或顶紧部4421可以为铝或铝合金等。弹性部4422包括橡胶件,在通过支撑组件442顶紧内伸段311时,所述橡胶件可在一定程度上保护内伸段311。当第二锁紧件443与第一锁紧件432锁紧时,支撑组件442将内伸段311顶紧在制冰格430的底部,从而保证了内伸段311与制冰格430紧密接触。
在一些实施例中,通过将固定盘440设置在制冰格430的底部,且固定盘440被配置为使制冷剂管400紧贴制冰格430的底部,由此,可以保证制冷剂管400与制冰格430有效接触,增大传热面积,使制冷剂管400产生的冷量能够最大效率地传递到制冰格430。并且,固定盘440与制冰格430之间设有通风道,风机组件420可直接吸入位于所述通风道内的冷风。
如图19所示,固定盘440还包括一个或多个回风孔441,一个或多个回风孔441位于固定盘440的底壁。
在一些实施例中,如图16所示,接水盘450与外壳体421连接,且接水盘450位于固定盘440的下方。接水盘450与固定盘440之间形成回风道。所述回风道内的风可通过回风孔441进入所述通风道,再被风机组件420吸入。
接水盘450被配置为承接制冰盘430的溢水或冷凝水,从而防止水滴落到储冰盒70内导致冰块冻结粘连。
在一些实施例中,接水盘450还包括加热件,所述加热件被配置为对接水盘450进行加热,以加快接水盘450内的水的蒸发速度。例如,所述加热件可以包括加热盘或加热管等。
在一些实施例中,如图3所示,制冰腔室403的后腔壁1310包括排水通道134,排水通道134位于限位部131(或内伸段311)的下方。接水盘450与排水通道134连通。例如,接水盘450朝向排水通道134向下倾斜,这样可以更快地排水,避免对制冰机60中的电路等元器件造成损坏。
在一些实施例中,如图18所示,制冰机60还包括第一连接组件4501和第二连接组件4502。接水盘450的前端通过第一连接组件4501与外壳体421可拆卸连接,接水盘450的后端通过第二连接组件4502与制冰格430的后端可拆卸连接。
例如,第一连接组件包括卡槽451和卡扣425,卡扣425与卡槽451相匹配。卡槽451设于接水盘450的前端,卡扣425设于外壳体421的后侧面。第二连接组件包括挂钩452和旋转轴433,旋转轴433与挂钩452相匹配。挂钩452设于接水盘450的后端,旋转轴433设于制冰格430的后端。
如图18和图30所示,接水盘450的安装和拆卸过程包括:当卡槽451与卡扣425连接,且接水盘450位于第一预定角度时,挂钩452钩在旋转轴433上(如图30中K1位置所示)。当卡槽451与卡扣425的配合被解除后,接水盘450可绕旋转轴433向下旋转第二预定角度,直至挂钩452与旋转轴433脱离配合(如图30中K2和K3位置所示),从而将接水盘450整体拆卸。将接水盘450拆卸后便于内伸段311的安装。接水盘450安装过程与拆卸过程相反,此处不再赘述。
在一些实施例中,如图3所示,排水通道134包括接水斗1340,接水斗1340位于内 伸段311的下方,接水斗1340的底部的后端向下倾斜。接水斗1340的顶部具有开口,接水斗1340的口径沿着排水通道134的水的流向逐渐递减。排水通道134的水的流向如图3中虚线所示。排水通道134包括排水管1341。排水管1341位于接水斗1340的底部的后端。排水管1341贯穿制冰腔室403的后腔壁1310设置。
在一些实施例中,如图3和图18所示,接水盘450还包括延伸段453。延伸段453设置在接水盘450的后端,接水盘450可通过延伸段453与排水通道134连接。例如,延伸段453位于内伸段311的下方,延伸端453与接水斗1340的开口相对应。延伸段453被配置为承接内伸段311滴落的冷凝水,以将冷凝水导流至接水斗1340。由此,可以防止冷凝水滴落至制冰腔室403的表面(如内底面),从而能够降低制冰腔室403的表面结霜的可能性。此外,排水通道134对接水盘450排出的水进行收集和引流,可及时将水排出,从而避免制冰机60损坏。
在一些实施例中,如图18、图22和图23所示,制冰机60还包括翻冰杆460和旋转驱动组件424。翻冰杆460位于制冰格430的上方,旋转驱动组件424位于外壳体421内。如图23所示。翻冰杆460的一端(例如前端)穿入外壳体421以与旋转驱动组件424连接,旋转驱动组件424被配置为驱动翻冰杆460沿预定方向旋转,以使制冰格430内的冰块脱出。
例如,如图22所示,翻冰杆460包括转轴461以及横杆462,横杆462设于转轴461的外侧。横杆462还包括多个翻冰部4621,制冰格430包括多个容置槽435,多个翻冰部4621与多个容置槽435一一对应设置。当旋转驱动组件424驱动翻冰杆460转动时,翻冰部4621可以将对应容置槽435内的冰块翻出,从而使冰块脱出制冰格430,并掉落到储冰盒70内。图22中的制冰格430包括十个容置槽435,横杆462包括十个翻冰部4621,但本公开并不限于此。
在一些实施例中,如图18和图22所示,上盖板470设于制冰格430的顶部,且上盖板470包括避让槽472和侧翼473。避让槽472位于上盖板470的顶部,且被配置为避让翻冰部4621。侧翼473由上盖板470的顶部向下延伸形成。
在一些实施例中,如图18所示,侧翼473包括多个风孔471。多个风孔471被配置为使风通过,多个风孔471的尺寸可以相同或不同。
在一些实施例中,如图22所示,侧翼473也可以不包括多个风孔471。
在一些实施例中,如图18和图26所示,当风机组件420工作时,循环风扇422从吸风侧抽风(例如从固定盘440与制冰格430之间的通风道抽取冷风),向出风侧吹风。
在图26中,所述出风侧为前侧,即循环风扇422向前吹风。冷风向前并向下运动,流经制冰腔室403的前向角落位置以及储冰盒70,继续流经制冰腔室403的后向角落位置,以及,接水盘450与固定盘440之间的所述回风道,并通过固定盘440底部的回风孔441,重新被循环风扇422吸入,如此循环。风循环的路径大致如图26中的箭头所示。
制冰腔室403内的空气在上述风循环中换热,有助于使制冰腔室403内保持温度均衡的状态,利于解决因温度差而产生的结霜、冰块粘连或融化等问题。例如,整个制冰腔室403内的制冰机60及储冰盒70所在的区域均达到温度均衡的状态。
在一些实施例中,制冰机60还可包括多个制冷剂管400。
在一些实施例中,如图31至图33所示,制冷剂管400包括第一制冷剂管3101和第二制冷剂管3102。第一制冷剂管3101和第二制冷剂管3102均位于制冰格430的底部,以对制冰格430中的容置槽435内的水进行降温,从而形成冰块。
例如,如图33所示,第一制冷剂管3101位于制冰腔室403内的管段和第二制冷剂管3102位于制冰腔室403内的管段均呈U型。第一制冷剂管3101位于制冰腔室403内的管段在所述参考面上的正投影,位于第二制冷剂管3102位于制冰腔室403内的管段在所述参考面上的正投影的外侧。在制冰机60高度方向上,第一制冷剂管3101和第二制冷剂管3102位于制冰腔室403内的管段处于同一高度位置或者不同高度位置。
需要说明的是,在制冷剂管400包括第一制冷剂管3101和第二制冷剂管3102的情况 下,固定盘440的内壁面上设有对应的支撑组件442以固定第一制冷剂管3101和第二制冷剂管3102,从而保证第一制冷剂管3101以及第二制冷剂管3102与制冰机60的制冰格430直接接触,避免两个制冷剂管400发生位置偏移。
通过制冷剂的热量交换,第一制冷剂管3101和第二制冷剂管3102的温度可达到大约-33℃,与第一制冷剂管3101和第二制冷剂管3102接触的制冰格430的温度可达到大约-25℃,从而冷却制冰格430内的水,使水变成冰。
在本公开一些实施例提供的制冰机60中,由于制冰机60包括至少两个制冷剂管400,从而能够与多种制冷流路以及多种腔室配合使用,满足更多的制冷需求。并且,两个制冷剂管400均对制冰机60进行制冷,能够提高制冰机60的工作效率。此外,由于设置了两个制冷剂管400,即使其中的一条制冷剂管400损坏,另一台制冷剂管400仍可保证制冰机60正常工作,提高了制冰机60的稳定性。
本公开的一些实施例还提供了一种冰箱的控制方法。所述冰箱包括上述制冰机60、制冷循环***20、注水装置100以及控制器90。制冰机60包括制冰格430。制冷循环***20包括制冰制冷流路300。控制器90还被配置为控制制冰制冷流路300对制冰机60中的制冰格430供冷,以使制冰机60制冰。
在一些实施例中,制冰机60也可通过风冷方式对制冰格430制冷。
如图34所示,冰箱的控制方法包括步骤101至步骤109。
在步骤101中,控制器90获取制冰启动指令。
用户可通过冰箱1的操作面板输入制冰启动指令,或通过与控制器90通信连接的移动终端设备(如手机等)输入制冰启动指令。
在步骤102中,控制器90控制注水装置100向制冰格430注水。
在步骤103中,控制器90判断此次注水时间是否等于第一预设时间T1。若是,则控制器90执行步骤104;若否,则控制器返回步骤102。
需要说明的是,第一预设时间T1为预先设定的每次注水的时间。第一预设时间T1满足T=n*T1,n为预先设定的注水次数,且为大于或等于2的自然数,T为制冰格430注满水所需的注水总时间。注水总时间T为根据制冰机60中的制冰格430的实际容量而预设的时间阈值。
在步骤104中,控制器90控制注水装置100停止注水,并记录此次注水时间。
在步骤105中,控制器90控制制冰机60开始制冰。
在步骤106中,控制器90判断当次注入制冰格430中的水是否已结冰。若是,则控制器90执行步骤107;若否,则控制器90返回步骤105。
在步骤107中,控制器90控制制冰机60停止制冰。
在一些实施例中,控制器90可通过制冰机60制冰的持续时间以判断当次注入制冰格430中的水是否已结冰。
例如,控制器90在控制制冰机60开始制冰后,通过计时器记录制冰的持续时间。当所述持续时间达到第二预设时间T2时,控制器90确定此次注入制冰格430中的水已结冰。
所述第二预设时间T2为预先设定的阈值。例如,第二预设时间T2为30min-90min之间的任一值(例如30min、40min、50min、60min、70min、80min或90min)。
当然,本公开并不限于此,在一些实施例中,控制器90还可通过检测制冰格430中的水的温度以判断当次注入制冰格430中的水是否已结冰。
例如,制冰机60包括温度传感器。所述温度传感器与控制器90电连接。所述温度传感器被配置为检测制冰格430中的水的温度。控制器90可通过所述温度传感器检测到的制冰格430中的水的温度判断当次注入制冰格430中的水是否已结冰。
控制器90在控制制冰机60开始制冰后,所述温度传感器实时检测当次注入制冰格430中的水的温度。当该温度小于-2℃,并且该温度保持小于-2℃的持续时间达到第三预设时间时T3时,控制器90确定此次注入制冰格430中的水已结冰。或者,当该温度小于-4℃时,控制器90确定此次注入制冰格430中的水已结冰。
所述第三预设时间T3为预设设定的阈值。例如,第三预设时间T3为10min-40min之间的任一值(例如10min、20min、25min、30min或40min)。
在步骤108中,在制冰机60停止制冰后,控制器90判断记录的注水时间之和是否等于注水总时间T。若是,则控制器90执行步骤109;若否,则控制器90确定制冰格430未注满水,控制器90返回步骤102。
在步骤109中,控制器90确定制冰格430已注满水,且制冰机60完成制冰。
需要说明的是,在制冰机60完成制冰后,控制器90将之前每次记录的注水时间删除,以避免干扰下次制冰。
制冰机60在制冰结束后的刮冰过程以及如何检测储冰盒70是否满冰的过程与前述类似,此处不再赘述。需要说明的是,当红外检测器检测到储冰盒70中的冰已经达到最大储冰量时,即使控制器90接收到制冰启动指令,也不控制制冰机60启动。
根据本公开的一些实施例的冰箱的控制方法,通过控制注水装置100和制冰机60交替工作,从而实现分多次向制冰格430注水以进行制冰。由于每次注入制冰格430中的水量均小于总注水量,因此相较于一次性注满水的方式,多次注水的方式中每次注水过程中产生的气泡较少。并且,水量少有利于空气从水中快速溢出,使每一次制作的冰层产生较少的气泡。多次注水和多次制冰的方式解决了冰块内部气泡多的问题,减少了冰块内部的气泡,提高了冰块的坚硬度。
在一些实施例中,如图35所示,在每次注水完成之后,且在制冰机60制冰之前,该方法还包括步骤110。
在步骤110中,在控制器90控制注水装置100停止注水后,控制器90判断制冰机60停止注水后的等待时间是否达到第四预设时间T4。若是,则控制器执行制冰步骤105;若否,则控制器90控制制冰机继续等待。
需要说明的是,第四预设时间T4为预设的时间阈值。例如,第四预设时间T4为1min-20min之间的任一值(例如,1min、5min、7min、10min、12min、15min或20min)。第四预设时间T4可根据每次注入的水量以及用户预期的制冰时间预先设置。
这样,通过在每次注水后以及每次制冰前增加等待时间,便于更多的空气从水中溢出,从而进一步减少制冰格430中的水内的气泡。
由于在实际使用中,可能会遇到用户在结束制冰前中途停止制冰的情况,因此,在一些实施例中,如图36所示,当控制器90在结束制冰前获取到制冰停止指令,且正在执行注水步骤102时,该方法还包括步骤111、步骤112以及步骤113。
在步骤111中,控制器90获取制冰停止指令。
在步骤111之后,控制器90控制注水装置100继续注水,直至此次注水时间等于第一预设时间T1,控制器90依次执行步骤104和步骤112。
在步骤112中,控制器90控制制冰机60停止制冰。
也就是说,控制器90控制注水装置100完成当次注水后再停止注水。并且,记录此次注水时间,然后停止制冰。
在步骤113中,控制器90判断是否获取到制冰启动指令。若是,则控制器90执行步骤110,并在步骤110之后执行制冰步骤105;若否,则控制器90控制制冰机60仍停止制冰。
当控制器90重新获取到制冰启动指令时,控制器90首先控制制冰机60制冰(即步骤105),或者,控制器90首先执行步骤110,并在执行步骤110之后执行制冰步骤105(如图36所示),从而将已注入制冰格430中的水重新冷冻成冰。然后控制器90判断记录的注水时间之和是否等于注水总时间T。若记录的注水时间之和小于注水总时间T,则确定制冰格430中未注满水,控制器90返回执行步骤102。若记录的注水时间之和等于注水总时间T,则确定制冰格430中已注满水,控制器90控制制冰机60结束制冰。
在一些实施例中,如图37所示,当控制器90在结束制冰前获取到制冰停止指令,且正在执行制冰步骤105时,该方法还包括步骤114和步骤115。
在步骤114中,控制器90获取制冰停止指令。
在步骤114之后,控制器90控制制冰机60继续制冰。当控制器90确定当次注入制冰格430中的水已结冰时,控制器90执行步骤107。
也就是说,控制器90控制制冰机60完成对当次注水的制冰后再停止制冰。
在步骤115中,控制器90判断是否获取到制冰启动指令。若是,则控制器90执行步骤108;若否,则控制器90控制制冰机60仍停止制冰。
当控制器90重新获取到制冰启动指令时,控制器90首先判断记录的注水时间之和是否等于注水总时间T。若记录的注水时间之和小于注水总时间T,则确定制冰格430中未注满水,控制器90返回执行步骤102以再次执行注水和制冰操作。若记录的注水时间之和等于注水总时间T,则确定制冰格430中已注满水,制冰机60完成制冰,控制器90控制制冰机60结束制冰。
为了便于叙述,以下主要以注水次数n等于3,且每次停止注水后的等待时间分别为第一时间Tt1、第二时间Tt2和第三时间Tt3为例进行说明。
控制器90在获取制冰启动指令后,控制注水装置100向制冰格430进行第一次注水。当第一次注水时间t1等于第一预设时间T1时,控制器90控制注水装置100停止注水,并记录第一次注水时间t1。在控制器90控制注水装置100完成第一次注水后,控制器90控制制冰机60等待第一时间Tt1。当第一时间Tt1等于第四预设时间T4时,控制器90控制制冰机60开始第一次制冰。
当注入制冰格430中的水已结冰时,控制器90控制制冰机60停止第一次制冰。此时,由于记录的注水时间之和小于注水总时间T,因此,控制器90返回执行注水步骤102。也就是说,控制器90控制注水装置100向制冰格430进行第二次注水。
当第二次注水时间t2达到第一预设时间T1时,控制器90控制注水装置100停止注水,并记录第二次注水时间t2。在控制器90控制注水装置100完成第二次注水后,控制器90控制制冰机60等待第二时间Tt2。当第二时间Tt2等于第四预设时间T4时,控制器90控制制冰机60开始第二次制冰,直至已注入制冰格430的水结冰,则停止第二次制冰。
此时,由于记录的注水时间之和(t1+t2)仍小于注水总时间T,因此,控制器90再次返回执行注水步骤102。也就是说,控制器90控制注水装置100向制冰格430进行第三次注水。
当第三次注水时间t3达到第一预设时间T1时,控制器90控制注水装置100停止注水,并记录第三次注水时间t3。在控制器90控制注水装置100完成第三次注水后,控制器90控制制冰机60等待第三时间Tt3。当第三时间Tt3等于第四预设时间T4时,控制器90控制制冰机60开始第三次制冰,直至已注入制冰格430的水结冰,则停止第三次制冰。
此时,由于记录的注水时间之和(t1+t2+t3)等于注水总时间T,因此,制冰机60完成制冰。
