然而,常规冰箱在安装时,要求冰箱周围包括后壁应留有100mm以上的空间以确保压机仓的通风散热,从而降低冰箱的能耗,由于冰箱周围与墙壁或其它物品之间具有足够的空间,因此冰箱后下部的压机仓背板上的进风口和出风口之间互不影响。当冰箱嵌入橱柜中后,为了合理节约空间,冰箱周围与橱柜间的距离较小,甚至冰箱的后壁贴紧橱柜壁放置,冰箱的侧壁与橱柜壁之间的距离小于30mm。

具体实施方式
以下将结合附图所示的各实施方式对本发明进行详细描述。
在本发明的各个图示中,为了便于图示,结构或部分的某些尺寸会相对于其它结构或部分扩大,因此,仅用于图示本发明的主题的基本结构。
应当理解的是尽管术语第一、第二等在本文中可以被用于描述各种元件或结构,但是这些被描述对象不应受到这些术语的限制。这些术语仅用于将这些描述对象彼此区分开。
实施例1
参看图1至图2,本发明一实施例提供的冰箱100,包括设于其后下部的压机仓1、前后相对设置的前壁2与后壁3、左右相对设置的一对侧壁4、以及储物间室。所述储物间室由前壁2、后壁3以及一对侧壁4围纳而成。
参看图2至图3,压机仓1包括内置空间11、围纳出内置空间11的仓壁12、以及布设于内置空间11中的散热风机13、压缩机14和蒸发器15。仓壁12包括设于内置空间11后方的背板121、以及设于内置空间11下方的底板122。
参看图4至图5,仓壁12上设置有第一风口123、第二风口124和第三风口。具体地,在本实施例中,压机仓1的背板121具有左右并排设置的第一风口123与第二风口124,第一风口123和第二风口124分别与冰箱100的后方空间连通,也即与外界相连通,以利于压机仓1通过其后部与外界环境进行气流交换。压机仓1的底板122设置有与冰箱100的下方空间连通的所述第三风口,也就是说,所述第三风口与外界连通以使压机仓1通过其底部与外界环境进行气流交换。在其它实施例中,第一风口123与第二风口124也可以设置于底板122上,而第三风口124设于背板上。
其中,第一风口123可以为进风口,也可以为出风口;当第一风口123为进风口时,第二风口124为出风口,所述第三风口也为进风口;当第一风口123为出风口时,第二风口124为进风口,所述第三风口也为出风口。
通过仓壁12上设置的第一风口123、第二风口124与所述第三风口,压机仓1的内置空间11具有第一风路和第二风路,所述第一风路自第一风口123经散热风机13连通第二风口124,所述第二风路自所述第三风口经散热风机13连通所述第二风口124。
为了便于描述,在本实施例中,以使用者面对冰箱100的后壁3作为参照,以自后壁3向冰箱100前壁2的方向为自后向前的方向,也即,冰箱100的前壁2位于后壁3的前方,以自第二 风口124朝向第一风口123的方向为自左向右的方向,也即,第一风口123位于第二风口124的右侧,则,定义靠近第一风口123一侧的侧壁4为右侧壁,远离第一风口123一侧的侧壁4为左侧壁。在其它实施例中,第一风口123也可以位于第二风口124的左侧。
参看图4至图5以及图7至图8,冰箱100还包括用于打开或关闭第一风口123的遮挡件。当第一风口123开启时,所述第一风路和所述第二风路均与外界形成循环回路;当第一风口123被所述遮挡件关闭时,所述第二风路与外界形成循环回路。
在本实施例中,所述遮挡件采用挡板16,挡板16活动设于第一风口123处,挡板16具有打开第一风口123的第一位置、以及关闭第一风口123的第二位置。通过设置挡板16,可以在冰箱100嵌入橱柜200时,关闭压机仓1背板121上的第一风口123,使压机仓1采用所述第二风路,也即风自压机仓1底板122上的所述第三风口经散热风机13连通压机仓1背板121上的第二风口124进行风循环。通过改变压机仓1内散热进风和出风的路径,从而使压机仓1中排出的热风与吸入压机仓1中的冷风互不串流,实现了冰箱100嵌入橱柜200中后压机仓1的高效散热,避免了采用所述第一风路,也即自压机仓1背板121上的第一风口123经散热风机13连通压机仓1背板121上的第二风口124时,由于第一风口123与第二风口124均位于压机仓1背板121上而导致的冷热风串流,引起压机仓1中的风温度较高,从而影响压缩机14与冷凝器的性能、以及冰箱100能耗的增加。
挡板16可以设于背板121的内侧,也可根据美观等需求设于背板121的外侧。
参看图2以及图5至图7,进一步地,冰箱100还包括驱动机构17,驱动机构17驱动挡板16于所述第一位置和所述第二位置之间运动,以使挡板16打开或遮蔽第一风口123。
参看图5至图6,进一步地,驱动机构17设置为推动杆171,推动杆171相对挡板16左右运动以推动挡板16由所述第一位置向所述第二位置运动,也即,推动挡板16遮蔽第一风口123使第一风口123处于关闭状态。推动杆171具有左右相对设置的第一端1711与第二端1712,第一端1711与挡板16连接;挡板16于所述第一位置时,第二端1712沿左右方向凸伸出冰箱100的侧壁4。
在本实施例中,第一端1711位于推动杆171的左端,而第二端1712位于推动杆171的右端,挡板16于所述第一位置时,第二端1712沿左右方向向右凸伸出冰箱100的右侧壁4。这样,当冰箱100嵌入橱柜200中时,推动杆171的第二端1712与橱柜200壁会发生干涉,在橱柜200的壁的作用下,推动杆171的第二端1712受力沿左右方向向左运动,并推动挡板16沿左右方向向左运动以遮蔽第一风口123,使第一风口123处于关闭状态。
在其它实施例中,当第一风口123位于第二风口124的左侧时,第一端1711位于推动杆171 的右端,而第二端1712位于推动杆171的左端,挡板16于所述第一位置时,第二端1712沿左右方向向左凸伸出冰箱100的左侧壁4。当冰箱100嵌入橱柜200中时,推动杆171的第二端1712与橱柜200壁会发生干涉,在橱柜200壁的作用下,推动杆171的第二端1712受力沿左右方向向右运动,并推动挡板16向右运动以遮蔽第一风口123,使第一风口123处于关闭状态。
参看图6,进一步地,第二端1712的端面设置为自后向前逐渐远离侧壁4的弧面或斜面。当冰箱100嵌入橱柜200中时,第二端1712的后端面先抵持橱柜200的壁,然后沿弧形端面过渡至前端面抵持橱柜200的壁,在橱柜200的壁的作用下,推动杆171自右向左逐渐运动,这样,通过第二端1712的端面与橱柜200壁沿前后方向相对运动,不仅可以省力,而且避免了第二端1712对橱柜200壁的损伤。
参看图5至图6,进一步地,驱动机构17还包括连接背板121与推动杆171的弹性件172,弹性件172通过推动杆171驱动挡板16自所述第二位置向所述第一位置复位运动,并使推动杆171稳定驱动挡板16沿左右方向运动;挡板16于所述第一位置时,弹性件172具有第一形变量;挡板16于所述第二位置时,弹性件172具有第二形变量;所述第二形变量大于所述第一形变量,也就是说,当驱动机构17驱动挡板16自所述第一位置向所述第二位置运动时,驱动机构17作用于弹性件172使其进一步发生弹性形变;挡板16于所述第二位置时,当外力撤销时,弹性件172为了克服其弹性形变,具有驱动挡板16自所述第二位置向所述第一位置运动复位的弹性恢复力。在本实施例中,弹性件172设于第一风口123的右侧。
参看图5至图6,为了进一步使推动杆171稳定地沿左右方向运动从而驱动挡板16稳定地左右运动,背板121设置有左右方向延伸的导轨173,弹性件172为套设于推动杆171外周的弹簧,推动杆171与所述弹簧内置于导轨173中,导轨173的内壁上设置有限位部1731,推动杆171上设置有凸缘1713,所述弹簧靠近第一风口123的一端也即左端抵持限位部1731,所述弹簧远离第一风口123的一端也即右端抵持凸缘1713。推动杆171压缩所述弹簧并推动所挡板16由所述第一位置向所述第二位置运动,所述弹簧靠近第一风口123的一端相对固定于背板121,推动杆171推动挡板16由所述第一位置向所述第二位置运动时,推动杆171的凸缘1713抵持所述弹簧的右端并压缩所述弹簧向左运动使其发生弹性形变。在其它实施例中,弹性件172也可以为波纹管、橡胶管等形式,只要其具有弹性形变即可。
参看图4至图5以及图7至图8,进一步地,背板121上设置有限位件1211,具体地,在本实施例中,限位件1211为限位柱。挡板16于所述第一位置时,挡板16打开第一风口123,挡板16与限位件1211之间具有空隙;挡板16于所述第二位置时,限位件1211抵持挡板16并限制挡板16自所述第二位置背离所述第一位置运动。限位件1211的设置限定了挡板16向左运动 的极限位置,确保了挡板16刚好运动至所述第二位置以遮蔽第一风口123,避免挡板16运动至与第一风口123错位而无法完全遮蔽第一风口123,而使压机仓1中排出的热风串流进压机仓1中,从而引起冰箱100能耗增加、冷凝器和压缩机14性能下降等问题。
进一步地,冰箱100还包括控制系统,所述控制系统包括采集单元和风机控制单元。所述采集单元用于采集冰箱100的上电信号、以及第一风口123的关闭信号和开启信号。所述风机控制单元与所述采集单元连接,并用于当所述采集单元采集到第一风口123的开启信号时,控制散热风机13以设定转速Nf1运转;当所述采集单元采集到第一风口123的关闭信号以及冰箱100的上电信号时,控制散热风机13以设定转速Nf2运转;其中,Nf2>Nf1。
优选地,Nf2为Nf1的110%~120%倍,且Nf1与Nf2均不超过散热风机13的额定转速。
这样,当第一风口123关闭且冰箱100上电时,也即冰箱100嵌入橱柜200且开机时,通过采集相关信号并控制散热风机13的转速提高,可以提高热空气的排出量和排出效率、以及冷空气的进风量和进风效率,解决由于压机仓1与外界进行空气交换的风口减少造成的散热不良的问题,实现冰箱100的自动控制和智能化。
进一步地,所述采集单元还用于采集所述储物间室的温度;所述风机控制单元还用于:当所述采集单元采集到第一风口123的关闭信号以及冰箱100的上电信号时,控制散热风机13以设定转速Nf2运转,直至所述储物间室的温度达到设定温度T时,控制散热风机13以设定转速Nf1运转。
参看图8,进一步地,冰箱100还包括设于所述遮挡件上的第一导电端18与设于仓壁12的第二导电端19。具体地,在本实施例中,第一导电端18设于挡板16上,第二导电端19设于限位件1211上。挡板16于所述第一位置,也即所述遮挡件打开第一风口123时,第一导电端18与第二导电端19相分离,所述采集单元采集到第一风口123的开启信号。挡板16于所述第二位置,也即所述遮挡件关闭第一风口123时,第一导电端18与第二导电端19相接触并产生电信号,所述采集单元采集到第一风口123的关闭信号。
为了使挡板16于所述第二位置时,第一导电端18与所述限位柱上的第二导电端19接触,第一导电端18的左端位于挡板16的左侧边缘对应所述限位柱处。第一导电端18的形状不限,只要不影响挡板16遮蔽第一风口123即可。
进一步地,所述控制单元还用于,当所述采集单元采集到第一风口123的开启信号时,控制压缩机14以设定转速Nc1运转;当所述采集单元采集到第一风口123的关闭信号以及冰箱100的上电信号时,控制压缩机14以设定转速Nc2运转;其中,Nc2>Nc1。这样,当第一风口123关闭且冰箱100上电时,也即冰箱100嵌入橱柜200且开机时,可以实现快速制冷,使冰箱100 快速达到设定温度T。
优选地,Nc2为Nc1的102%~110%倍,且Nc1、Nc2均不超过压缩机14的额定转速。
参看图2,进一步地,背板121设置有上下相对的两条翻边1212,两条翻边1212沿左右方向延伸,挡板16的上下两端分别插置于翻边1212的凹槽中以限制挡板16横向运动的轨迹,挡板16可相对翻边1212沿左右方向滑动以在所述第一位置和所述第二位置之间往复。翻边1212的设置位置与挡板16相匹配,挡板16设于背板121内侧时,相应地翻边1212也设置于背板121内侧;挡板16设于背板121外侧时,翻边1212也相应设置于背板121的外侧。
参看图4至图5,挡板16包括间隔设置的开口161与肋条162,挡板16于所述第一位置时,开口161对齐第一风口123以打开第一风口123;挡板16于所述第二位置时,肋条162遮蔽第一风口123以关闭第一风口123,挡板16与限位件1211之间的所述空隙的宽度与开口161的宽度相同,这样,挡板16运动至抵持限位件1211时,肋条162刚好遮蔽第一风口123。
实施例2
实施例2与实施例1的区别在于:
驱动机构17为电驱动机构,所述控制系统还包括与所述电驱动机构相连接的驱动控制单元,在所述驱动控制单元的控制下,所述电驱动机构开启以驱动所述遮挡件关闭第一风口123。
参看图7,所述电驱动机构包括电磁铁174与导磁块175,电磁铁174与导磁块175的其中一者设于背板121上,电磁铁174与导磁块175的其中另一设于挡板16上,电磁铁174通电后配合于导磁块175,以驱动挡板16由所述第一位置向所述第二位置运动。具体地,在本实施例中,电磁铁174设于背板121上,导磁块175设于挡板16上。
进一步地,冰箱100还包括弹性复位件176,弹性复位件176驱动挡板16自所述第二位置向所述第一位置复位运动以打开第一风口123。
进一步地,冰箱100还包括传感器,所述传感器检测冰箱100与障碍物的位置信息,所述驱动控制单元与所述传感器连接,所述驱动控制单元用于根据所述位置信息控制所述电驱动机构通电开启,以使所述电驱动机构驱动挡板16自所述第一位置运动至所述第二位置。
具体地,在本实施例中,所述传感器为设于侧壁4上的距离传感器,所述距离传感器用于检测冰箱100与障碍物之间的距离信息,所述采集单元与所述距离传感器连接并采集冰箱100与障碍物之间的距离信息,当冰箱100与所述障碍物之间的距离小于设定距离D时,所述驱动控制单元控制电磁铁174通电导磁以驱动挡板16自所述第一位置运动至所述第二位置。
实施例2与实施例1除上述区别外,其它结构均相同,于此,不再赘述。
实施例3
参看图9,本发明还提供了一种冰箱100的控制方法,其包括步骤:
采集冰箱100的上电信号、第一风口123的关闭信号;
当采集到第一风口123的开启信号,所述第一风路和所述第二风路均与外界形成循环回路时,控制压机仓1中的散热风机13以设定转速Nf1运转;
当采集到冰箱100的上电信号,并采集到第一风口123的关闭信号,所述第二风路与外界形成循环回路时,控制散热风机13以设定转速Nf2运转;
其中,Nf2>Nf1。
这样,当冰箱100上电且第一风口123关闭时,也即冰箱100嵌入橱柜200且开机时,通过提高散热风机13的转速,可以提高热空气的排出量和排出效率、以及冷空气的进风量和进风效率,解决由于压机仓1与外界进行空气交换的风口减少造成的散热不良的问题,实现冰箱100的自动控制和智能化。
进一步地,冰箱100的控制方法还包括步骤:
当采集到冰箱100的上电信号,并且采集到第一风口123的关闭信号,所述第二风路与外界形成循环回路时,控制散热风机13以设定转速Nf2运转,直至冰箱100的储物间室的温度达到设定温度T时,控制散热风机13以设定转速Nf1运转。
当所述储物间室的温度达到冰箱100的设定温度时,散热风机13以正常转速运转即可实现压机仓1的正常散热。
为了说明本实施例的冰箱100对压机仓中的冷热风串流的改进效果,对冰箱的压机仓散热进行仿真模拟,环境温度32℃,具体如下:
对照组1:对普通冰箱进行未嵌入橱柜时的仿真模拟,冰箱的左侧壁、右侧壁与障碍物之间的距离均设置为100mm,其中,压机仓背板上设置第一风口与第二风口,压机仓底板上设置有第三风口,且第一风口、第二风口与第三风口均处于打开状态,仿真效果图参看图10;
对照组2:对普通冰箱嵌入橱柜时的仿真模拟,冰箱的左侧壁、右侧壁与障碍物之间的距离均设置为3mm,其中,压机仓背板上设置第一风口与第二风口,压机仓底板上设置有第三风口,且第一风口、第二风口与第三风口均处于打开状态,仿真效果图参看图11;
试验组:对本实施例的冰箱嵌入橱柜时的仿真模拟,冰箱的左侧壁、右侧壁与障碍物之间的距离均设置为3mm,其中,压机仓背板上设置第一风口与第二风口,压机仓底板上设置有第三风口,第一风口处于关闭状态,第二风口与第三风口均处于打开状态,仿真效果图参看图12。
对上述三组冰箱进行仿真模拟分析,得到三组冰箱的有效风量、进风的平均温度、冷凝器的平均温度的仿真模拟分析结果如下表:
指标 对照组1 对照组2 试验组
有效风量(L/min) 1513 1120 1379
进风平均温度(℃) 32.5 36.9 32.7
冷凝器平均温度(℃) 41.9 45.7 42.1
参看图10至图12,结合上述仿真分析数据可知,普通冰箱在嵌入橱柜时,由于压机仓背板上的风口排出的热风会串流进入压机仓中,导致压机仓中进风发平均温度升高,有效风量降低,冷凝器的温度也显著提高;与普通冰箱相比,本实施例的冰箱在嵌入橱柜时,通过遮蔽第一风口,可以有效避免压机仓中排出的热风串流进入压机仓中,增加进入压机仓中的有效风量,降低压机仓中进风的平均温度和冷凝器的平均温度,达到接近正常冰箱未嵌入橱柜中的效果。
也就是说,本实施例的冰箱100通过改变压机仓1内散热进风和出风的路径,从而使压机仓1中排出的热风与吸入压机仓1中的冷风互不串流,避免了由于第一风口123与第二风口124均位于压机仓1背板121上而导致的冷热风串流、压机仓1中的进风温度较高、压缩机14与冷凝器的性能影响和冰箱100能耗增加的问题。
与现有技术相比,本发明提供的冰箱100、冰箱100的控制系统、以及冰箱100的控制方法,其有益效果在于:本发明的冰箱100通过改变压机仓1内散热进风和出风的路径,从而使压机仓1中排出的热风与吸入压机仓1中的冷风互不串流,实现了冰箱100嵌入橱柜200中后压机仓1的高效散热;通过设置驱动机构17以驱动挡板16打开或关闭第一风口123;通过推动杆171的第二端1712沿左右方向凸伸出冰箱100的侧壁4,在冰箱100嵌入橱柜200时可以借助橱柜200的作用实现挡板16自动关闭第一风口123,并通过弹簧实现推动杆171的复位和稳定,以及通过导轨173实现对推动杆171的引导和稳定作用;通过电磁铁174与导磁块175的配合可以自动控制挡板16关闭第一风口123,通过复位弹簧176可以实现导磁块175的复位;通过在挡板16和背板121上设置第一导电端18和第二导电端19,当挡板16运动至关闭所述第一风口123时,产生电信号;通过在背板121上设置限位件1211可以实现挡板16与第一风口123的配合以刚好遮蔽所述第一风口123;通过设置控制系统,采集冰箱100的相关信号并控制散热风机13的转速提高,可以提高热空气的排出量和排出效率、以及冷空气的进风量和进风效率,解决由于压机仓1与外界进行空气交换的风口减少造成的散热不良的问题,实现冰箱100的自动控制和智能化;通过设置传感器检测冰箱100与障碍物的位置信息,以判断冰箱100是否嵌入橱柜200中,实现了冰箱100的智能化;另外,通过冰箱100的控制方法,采集冰箱100的上电信号和第一风口123的打开、关闭信号以控制散热风机13的转速改变,大大提高了冰箱100的智能化程度。仿真模拟试验也进一步验证了本实施例的冰箱在嵌入橱柜时,可以有效避免压机仓中排出的热风串 流进入压机仓中,增加进入压机仓中的有效风量增,降低压机仓中进风的平均温度和冷凝器的平均温度。
