为了使本技术领域的人员更好地理解本发明中的技术方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。
参见图1至图3,本发明一实施方式提供一种冰箱100,冰箱100包括箱体110以及门体,门体可枢转连接于箱体110以用于开闭箱体110。冰箱100内还可设置有制冰间室113,制冰间室113内可安装有制冰装置150。箱体110内形成的储物间室可包括冷藏间室111和冷冻间室112,门体可包括用于开闭冷藏间室111的冷藏门体121和用于开闭冷冻间室112的冷冻门体122。
在本实施方式中,制冰间室113可设置在冷藏门体121上,也可在冷藏间室111内设置独立的制冰间室113。冰箱100还可包括用于向制冰间室113供应冷气的制冷***。冰箱100的箱体110一侧可设置有制冰蒸发器间室130和箱体蒸发器间室140。如冰箱100的冷藏间室111或冷冻间室112内可设置有蒸发器间室,制冷***可包括安装于蒸发器间室内的制冰蒸发器131以及送风风机,制冰间室113可通过风道与蒸发器间室连通,送风风机可按照预先设定的程序间歇性启动以将蒸发器间室内的冷气送至制冰间室113内部。
箱体蒸发器间室140内可设置有箱体蒸发器141,箱体蒸发器间室140可通过风道与储物间室连通向储物间室内供应冷气。箱体110一侧还可设置有压机仓,压机仓内可设置有压缩机和冷凝器。制冰蒸发器131和箱体蒸发器141可以相对并联连接于压缩机和冷凝器。在制冷***运行过程中,经压缩机压缩的制冷剂流经冷凝器后可通过一进二出电磁阀选择性的流向制冰蒸发器131或箱体蒸发器141。
制冰间室113以及储物间室内部均可安装有温度传感器,当制冰间室113或者
储物间室内的温度高于对应的预设温度时,可启动压缩机向对应的蒸发器供应制冷剂进行制冷。
在本实施方式中,制冰装置150可包括制冰盘151、电机152以及检冰杆153,制冰装置150还包括设置于制冰盘151下方的储冰盒132。在制冰盘151的长度方向上,电机152可位于制冰盘151的一侧,在制冰盘151的宽度方向上,检冰杆153可位于制冰盘151的一侧,电机152转动可带动检冰杆153上下运动以检测储冰盒132内冰量是否达到满冰状态,若检冰杆153的运动受到阻碍可判定储冰盒132内的冰量达到满冰状态。制冰盘151上还可设置有加热元件,如制冰盘151的底部可设置有加热丝,在需要进行翻冰时,可启动加热丝使制冰盘151内的冰块和制冰盘151分离以便于进行脱冰。
在本发明一实施方式中,在制冰盘151的底部可安装有温度传感器,可根据温度传感器检测到的温度判断制冰盘151内的水是否完全冻结,或者根据注入液态水后的冷冻时长判断制冰盘151内的水是否完全冻结,当检测到制冰盘151内的水完全冻结后,可以发出制冰结束信号。冰箱100内还设置有控制装置,控制装置配置为当接收到制冰结束信号时,控制送风风机关闭,并控制电机152驱动检冰杆153检测储冰盒132内是否满冰。
在本实施方式中,送风风机可以根据预先设定的程序间歇性运转,如可在制冰间室113内设置温度传感器,当检测到制冰间室113内的温度低于预设温度时,即可启动制冷***,如启动压缩机和送风风机以向制冰间室113内供应冷气。
当接收到制冰结束信号时,制冰盘151中的水已经完全冻结,需要进行脱冰,此时,若送风风机处于运行过程中,可以控制送风风机关闭,以节省能量。若检冰杆153检测到储冰内未满冰,可启动脱冰程序,控制装置可控制加热元件开启,使得制冰盘151底部的冰块融化以便于进行脱冰。
在本实施方式中,预设时长可以根据制冰装置150的性能和需求设置,可以在加热元件开启10s后再对制冰装置150进行脱冰,当然,预设时长也可以为0,也就是可在开启加热元件的同时控制制冰装置150脱冰。
如此,当接收到制冰结束信号时,立即关闭送风风机,但不启动加热元件,而当检测到储冰盒132内的冰量未满冰可以进行脱冰时,才启动加热元件,能够节约能耗,避免制冰盘151内的冰块无必要的融化和二次冻结。
在本发明一实施方式中,控制模块还配置为:
若接收到制冰结束信号时,送风风机处于运行状态,且检冰杆153检测到储冰
盒132内满冰,则控制送风风机开启。
在本实施方式中,若在接收到制冰结束信号时送风风机处于运行状态,可判断此时制冰间室113的温度偏高,需要运行制冷***进一步降低制冰间室113内的温度以保证制冰装置150的正常运行。当检冰杆153检测到储冰盒132内满冰时,此时由于储冰盒132内存储空间已满,无法对制冰盘151进行脱冰,因此,无需开启加热元件,此时,需要将制冰盘151内的冰块以及储冰盒132内的冰块均保持在冻结状态,因此,需要将制冰间室113的温度保持在预定温度以下,控制装置可控制送风风机开启以继续对制冰间室113制冷。
进一步的,在本发明一实施方式中,制冰装置150还包括用于脱冰的拨冰件154以及传动装置,传动装置连接电机152、拨冰件154以及检冰杆153。如图3所示制冰装置150处于制冰状态,拨冰件154处于第一位置。电机152沿第一方向A旋转可驱动拨冰件154朝远离制冰盘151的方向旋转大约90°-135°至第二位置,同时可带动检冰杆153抬升,电机152沿与第一方向A相反的第二方向旋转时,可带动拨冰件154由第二位置返回第一位置,此时可带动检冰杆153下落。
在本实施方式中,当接收到制冰结束信号时,控制模块可控制电机152沿第一方向A旋转,带动拨冰件154由第一位置旋转至第二位置后再控制电机152沿第二方向旋转,带动拨冰件154由第二位置旋转回复至第一位置,同时带动检冰杆153抬升后下落以检测储冰盒132内是否满冰。
在本实施方式中,拨冰件154包括与传动装置连接的转轴1541以及自转轴1541的圆周面沿转轴1541径向延伸的若干拨冰齿1542,若干拨冰齿1542间隔分布且位于同一平面内,若储冰盒132内未满冰,则在加热元件开启预设时长后控制电机152沿第二方向转动驱动拨冰件154旋转至少一周,在拨冰齿1542的作用下可以将冰块从制冰盘151内分离。
在本实施方式中,电机152可为步进电机。参见图4、图5,传动装置可包括减速齿轮组161以及拨冰齿轮162,减速齿轮组161的输入端与电机152的输出端连接,减速齿轮的输出端与拨冰齿轮162啮合,拨冰齿轮162与拨冰件154连接,电机152转动可带动减速齿轮组161运动,进而带动拨冰齿轮162和拨冰件154转动。
拨冰齿轮162的两侧分别设置有第一凸轮和第二凸轮163,第二凸轮163与摆动齿轮164旋转连接,拨冰齿轮162带动第二凸轮163在一定范围内旋转时能够带动摆动齿轮164在一定角度范围内旋转,摆动齿轮164的一侧设置有弧形齿。传动装置还可包括与检冰杆153连接的检冰齿轮167,以及传动连接摆动齿轮164和检冰齿
轮167的连接齿轮结构,连接齿轮结构可包括同轴设置的第一连接齿轮165和第二连接齿轮166,第一连接齿轮165可与摆动齿轮164啮合,第二连接齿轮166可与检冰齿轮167啮合。
在本实施方式中,电机152转动带动拨冰齿轮162由第一位置沿第一方向A旋转至第二位置,以及沿第二方向旋转带动拨冰齿轮162由第二位置旋转回第一位置时,第二凸轮163带动摆动齿轮164旋转摆动,摆动齿轮164带动第一连接齿轮165、第二连接齿轮166以及检冰齿轮167运动,进而带动检冰杆153上下运动,检测储冰盒132内是否满冰。
在本实施方式中,第一连接齿轮165和第二连接齿轮166可设置有弹性连接件,当储冰盒132内满冰,检冰杆153受到的阻力大于弹性连接件的弹性力时,第一连接齿轮165和第二连接齿轮166发生相对运动,不会产生堵转。
在本实施方式中,可以在检冰齿轮167上安装磁铁并在传动装置的壳体上设置霍尔传感器,从而可以检测检冰齿轮167的旋转角度,根据检冰齿轮167的旋转角度判断储冰盒132内是否满冰。当然,磁铁也可安装于与检冰齿轮167啮合的第二连接齿轮166上,相应的,可以改变霍尔传感器的位置。
如此,可以在接收到制冰结束信号后,控制检冰杆153进行检冰,此时,拨冰杆朝与脱冰方向相反的第一方向A运转,拨冰杆不会与制冰盘151中的冰产生干涉。
进一步的,在本发明一实施方式中,当所述拨冰件154处于第一位置时,拨冰齿1542位于制冰盘151的外侧,若干拨冰齿1542所在的平面与制冰盘151的开口所在平面呈锐角。如此,能够避免制冰过程中,制冰盘151内的水溅出导致拨冰件154冻结。
在本发明一实施方式中,控制模块具体配置为:
若检冰杆153检测到储冰盒132内未满冰,则控制拨冰件154旋转两周后关闭电机152。
在本实施方式中,为了避免拨冰件154冻结,拨冰齿1542倾斜设置,拨冰齿1542所在的平面与制冰盘151的开口所在平面呈锐角,因此,在驱动拨冰件154旋转一周脱冰时,可能导致部分冰块遗留,旋转拨冰齿1542转动两周可以保证制冰盘151内的冰块全部脱出。
进一步的,在本发明一实施方式中,控制模块还配置为:
电机152驱动拨冰件154沿第二方向旋转一周至第一位置时,控制加热元件关闭。
在本实施方式中,拨冰件154旋转第一周的过程中,制冰盘151中的冰块已经大部分与制冰盘151分离并在拨冰件154的作用下脱至储冰盒132中,在拨冰件154旋转一周返回至第一位置时,制冰盘151中仅留存少量的冰块,此时,控制加热元件关闭不会影响拨冰件154脱冰,且可以避免制冰盘151的温度过高导致剩余冰块过度融化,同时可以避免制冰间室113温度进一步升高。因制冰结束后间室温度越高,下一轮制冰所需时间就越长,因此,可以节省能耗,提升制冰效率。
进一步的,在本发明一实施方式中,控制模块还配置为:
电机152驱动拨冰件154沿第二方向旋转两周至第一位置时,控制送风风机开启。
在本实施方式中,拨冰件154旋转两周至第一位置时,此时脱冰过程结束,可开启供水装置向制冰盘151中供水以继续进行制冰。由于制冰结束后,制冰间室113的温度过高,无法进行制冰过程,因此,需要开启制冷***向制冰间室113内供应冷气。在拨冰件154旋转两周脱冰完全结束后再开启送风风机,可避免在关闭加热元件后未从制冰盘151中脱出的冰二次冻结,影响脱冰过程。
