Description

一种冰箱
本申请要求在2020年02月27日提交中国专利局、申请号为202010125511.1、发明名称为“一种冰箱”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及储藏设备技术领域，尤其涉及一种冰箱。
背景技术
随着生活质量的日益提高，具有容积大、功能多、分类储存等特点的多门冰箱越来越多，而人们对冰箱产品的智能化的要求程度也越来越高。现有冰箱产品的层板多为位置固定不变的层板，通常在冰箱储藏室内部的相对侧壁上成型胆筋，层板放置于胆筋上即可。为了使层板的高度可调，一般是在储藏室的内壁上预留数个胆筋，从而用户可以将层板放置于不同高度的胆筋上，来改变层板的高度，但是，由于胆筋的位置不能改变，所以层板之间的间隙大小不能根据存放物品的大小随意调节，造成冰箱内部的空间利用率低，影响用户体验。另外，近年来，大容积冰箱的需求量逐渐提升，导致冰箱高度有升高的趋势，因此，最上层层板上储存的物品存取困难也成为困扰用户的问题。

具体实施方式
下面结合附图对本申请实施例提供的冰箱进行详细描述。
在本申请的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
图1为本申请实施例提供的可自动调节层板高度的冰箱的升降机构整体结构示意图。如图1所示，该冰箱包括层板001及与层板001连接的滚珠丝杆组件，滚珠丝杆组件包括配套的滚珠丝杆002和滚珠螺母003以及固定在滚珠丝杆002底部的传动齿轮004，传动齿轮004与电机005连接且由电机005带动旋转，层板001的两端各固定有一个安装座006，安装座006与层板001固定，安装座006上设有两个通孔：第一通孔007和第二通孔008，滚珠螺母003设置于第一通孔007内从而与安装座006固定，第二通孔008内穿设有导向杆009，对安装座006起到平衡支撑以及导向的作用，有效防止安装座006以及层板001倾斜，在滚珠丝杆002和导向杆009的顶端和底端分别设置有固定座010，该固定座010与储藏室的侧壁固定连接。当滚珠丝杆002在电机005带动下旋转时，滚珠螺母003在滚珠丝杆002上上升或下降，将旋转力转向为轴向力，从而带动安装座006以及层板001上升或下降。
上述方案通过将两组滚珠丝杆组件分别设置于层板001的两侧，在使用时，通过两个电机005分别带动对应的传动齿轮004转动，从而带动对应的滚珠丝 杆002转动，以使对应的滚珠螺母003上下移动，由此带动层板001上下移动，但是，通过两个电机005分别控制对应的滚珠丝杆组件运行，会出现两个电机005运行不同步的情况，当两个电机005运行不同步时，会导致两个滚珠丝杆002的转动速度不同，两个滚珠螺母003上下移动的速度不同，从而导致两个滚珠螺母003不处于同一平面内，使层板001倾斜，这样会导致滚珠螺母003与对应的滚珠丝杆002之间的螺纹连接面摩擦力增大，进而导致滚珠螺母003与对应的滚珠丝杆002之间不能相对转动，影响层板001正常升降，降低用户体验感。
图2是本申请实施例提供的冰箱整体结构示意图，如图2所示，冰箱具有近似长方体形状，其外观由限定储存空间的储藏室101和设置在储藏室101中的多个门体200限定。储藏室101为具有开口的箱体100，储藏室101被竖直分隔成下方的冷冻室101A以及上方的冷藏室101B，所隔开的空间中的每一个可具有独立的储存空间
在一些实施方式中，冷冻室101A限定在储藏室101的下侧并且可通过抽屉式冷冻室门200A选择性地覆盖。限定在冷冻室101A上方的空间被隔成左侧和右侧以分别限定冷藏室101B。冷藏室101B通过可枢转地安装在冷藏室101B上的冷藏室门200B选择性地打开或者关闭
在一些实施方式中，储藏室101包括位于下侧的储物抽屉110。图3为本申请实施例提供的箱体内部储藏室结构示意图。如图2、图3所示，所述储物抽屉110设置有两层，设置于下层的储物抽屉110被分隔为左侧和右侧两部分，分别为干保鲜抽屉和湿保鲜抽屉，设置于上层的储物抽屉110用于储存一些较长或者体积较大的食材；该储藏室101还包括位于所述储物抽屉110上方的层板， 所述层板包括固定层板120和升降层板130，固定层板120固定不动，升降层板130由驱动机构驱动，并且驱动机构与升降层板130之间通过升降组件连接，升降组件可将驱动机构输出的旋转力转换为上下移动的轴向力。
在一些实施方式中，升降层板130与固定层板120的位置不唯一，可以将升降层板130设置于固定层板120上方，也可以将固定层板120设置于升降层板130的上方。图4为本申请实施例提供的箱体内部储藏室主视图。在一些可能的实施方式中，如图4所示，将升降层板130设置于固定层板120的下方。
本申请的另一实施例中，所述储藏室101中可以只设置多个升降层板130，不设置固定层板120，对于每一个升降层板130均设置对应的驱动机构和升降组件，从而分别控制每一个升降层板130升降，在使用时，用户可以根据自己的使用情况，调节相邻两个升降层板130之间的距离，使储藏室101内的空间利用率更高。
图5为本申请实施例提供的升降层架的整体结构示意图，图6为本申请实施例提供的升降层架的侧视图；图7为本申请实施例提供的滑轨与支撑座之间的连接结构俯视图；图8为本申请实施例提供的滑轨、支撑座、连接板以及悬臂的连接结构剖视图。如图4、图5所示，升降组件包括分别固定于所述储藏室101内相对的两个侧壁上的两个滑轨300，滑轨300沿竖直方向设置；如图6所示，两个所述滑轨300上均滑动连接有支撑座400，两个支撑座400分别与所述升降层板130的两侧连接，如图7、图8所示，支撑座400上部固定有调节板440；两个调节板440上均滑动连接有调节块460，调节块460可相对于调节板440沿竖直方向滑动，两个调节块460上均固定连接有牵引绳500，两根牵引绳500的另一端均与驱动电机600的输出轴固定连接。
在本申请的一些实施例中，采用牵引绳500牵引的方式，通过驱动电机600带动两根牵引绳500牵引两侧的支撑座400沿滑轨300上下滑动，从而使升降层板130随两侧的支撑座400上下移动，由于只设置一个驱动电机600，从而避免出现两侧的支撑座400升降速度不同的情况，确保升降层板130在上下移动过程中保持水平；并且在支撑座400上设置有调节板440与牵引绳500上的调节块460相互配合，由于调节块460可相对于调节板440沿竖直方向滑动，从而当升降层板130的两侧高度出现差距时，可通过调节调节块460的高度，当调节块460上下滑动时，由于牵引绳500具有一定张力，因此，会使对应的牵引绳500的长度被拉长或者缩短，当牵引绳500的长度被改变后，则会带动对应的支撑座400上升或者下降，从而实现对升降层板130水平度进行微调的目的，保证升降层板130能够正常升降。
图11为本申请实施例提供的支撑座结构示意图。如图8、图11所示，调节板440平行于所述储藏室101内相对的两个侧壁，所述调节板440上开设有调节槽441，所述调节槽441水平方向贯穿所述调节板440，且所述调节槽441沿竖直方向延伸，如图12所示，所述调节块460上设置有调节螺钉461，所述调节螺钉461由所述调节板440的一侧穿过所述调节槽441，并与所述调节块460螺纹连接。在使用时，当升降层板130的两侧高度不同时，可通过将其中一侧的调节螺钉461拧松，然后拖动调节块460沿调节槽441上下移动，当该调节块460的高度改变后，其对应的牵引绳500的长度会相应改变，从而对应的支撑座400也会沿滑轨300上下滑动，以实现对升降层板130进行调平，当调平后只需拧紧调节螺钉461即可。
为便于用户对调节块460进行上下调节，如图7、图8所示，本申请实施例 提供的所述调节板440的顶面上固定连接有垂直于所述调节板440的限位板450，所述限位板450上沿竖直方向开设有螺纹孔451，所述螺纹孔451内设置有压紧螺钉452，所述压紧螺钉452的端部与所述调节块460的顶面抵接。如图6所示，当需要对升降层板130进行微调时，只需先适当拧松较高一侧的调节螺钉461，然后拧紧对应的压紧螺钉452，当压紧螺钉452向下移动时，会挤压调节块460向下移动，从而对应的支撑座400向下滑动，进而使升降层板130较高的一侧降低，当升降层板130保持水平后，拧紧调节螺钉461即可。
图12为本申请实施例提供的调节块结构示意图。如图12所示，所述调节螺钉461至少设置有两个，至少两个所述调节螺钉461沿竖直方向排列分布。如图11所示，通过在调节槽441内沿竖直方向设置至少两个调节螺钉461，从而形成两个以上的连接点，能够防止调节块460绕调节螺钉461转动。
图9为本申请实施例提供的滑轨、支撑座、连接板以及悬臂的连接结构剖视图；图10为本申请实施例提供的支撑座、连接板以及悬臂之间的连接结构示意图。如图9、图10所示，支撑座400上转动连接有滚轮410，滑轨300上沿竖直方向开设有滑槽310，滚轮410设置于滑槽310内、并可沿滑槽310滑动。采用滑轨300和滚轮410作为滑动组件，将滚轮410转动连接在支撑座400上，从而使支撑座400能够相对滑轨300滑动，支撑座400与升降层板130连接，滑轨300固定于储藏室101的内壁上，在支撑座400上固定连接有牵引绳500，牵引绳500的另一端与驱动电机600的输出轴连接，通过驱动电机600转动使牵引绳500拉动支撑座400沿滑轨300滑动，从而实现升降层板130上升或者下降，由于滑轮在滑轨300上的滑槽310内滑动，因此，不会对滑轮以及滑轨300形成压力，保证在升降层板130上放置的食材重量较大时，也不会对滑轮以 及滑轨300造成损坏，从而确保升降层板130能够正常上升或者下降，提高升降层板130的储藏量。
在本申请的一些实施方式中，升降组件采用牵引绳500牵引的传动方式，牵引绳500本身较细，不需要占用很大空间，并且采用牵引绳500牵引的传动方式，只需要一个驱动电机600，即可收回或者释放牵引绳500，然后通过牵引绳500拉动支撑座400，使支撑座400带动升降层板130上升或者下降，并且升降层板130上防止的食材的重量，均由牵引绳500承受，而牵引绳500只要强度够大，即可拉动升降层板130滑动，对于滑轨300和滚轮410不会形成压力，并且相比现有技术中的滚珠丝杆组件，本申请实施例的牵引绳500、滑轨300以及滚轮410组成的升降组件结构简单，占用空间小，能够增加储藏室101的有效使用空间。
为便于用户控制升降层板130升降，如图2所示，在储藏室101的内壁上设置有控制开关140，控制开关140用于控制驱动电机600正转、反转或者停止，从而调节升降层板130上升或者下降。
在本申请的一些实施方式中，控制开关140，可以设置三个按钮，分别为上升按钮、下降按钮和停止按钮，上升按钮上设置有向上箭头标识，下降按钮上设置有向下箭头标识，停止按钮上设置有停止标识；也可以设置两个按钮，分别为上升/停止按钮和下降/停止按钮，上升/停止按钮用于控制升降层板130上升或者上升停止，下降/停止按钮用于控制升降层板130下降或者下降停止。
为防止支撑座400与滚轮410之间发生相对转动，本申请实施例提供的所述支撑座400上转动连接有至少两个所述滚轮410，至少两个所述滚轮410沿所述滑槽310的长度方向排列、并设置于所述滑槽310内。通过在支撑座400上 转动了连接多个滚轮410，确保支撑座400不会相对滚轮410发生转动，从而保证升降层板130不会倾斜。
图13为本申请实施例提供的滑轨结构示意图。在一些实施例中，为防止升降层板130在上升或者下降至极限位置时，滚轮410从滑轨300的端部脱出，如图7、图13所示，滑槽310沿长度方向的两端的内壁上均设置有限位凸起320。通过滑槽310两端的限位凸起320可限制滚轮410的滑动行程，从而防止滚轮410与滑轨300分离，导致升降层板130不能正常升降。
如图4、图5所示，在本申请的一些实施例中，两个所述滑轨300的上方均设置有定滑轮510，两根所述牵引绳500的中部分别绕过对应的所述定滑轮510。通过在滑轨300的上方设置定滑轮510，使两个支撑座400上的牵引绳500的中部分别绕过对应的定滑轮510，通过定滑轮510转换牵引绳500的牵引方向，从而将两根牵引绳500的另一端均与驱动电机600的输出轴固定连接，当驱动电机600收方牵引绳500时，由于定滑轮510改变了牵引绳500的牵引方向，从而使牵引绳500与调节块460连接的一端的牵引力沿竖直方向，在升降过程中不会存在其他方向的分力，使牵引绳500承受的拉力等于升降层板130以及升降层板130上的食材的整体的重量，从而能够延长牵引绳500的使用寿命。
本申请实施例提供的所述支撑座400与升降层板130之间的固定方式不唯一，可直接通过焊接或类似的固定方式使支撑座400与升降层板130的侧边固定，也可以通过以下连接方式，如图9、图10所示，所述支撑座400上设置有悬臂430，所述悬臂430设置于所述升降层板130的下方，所述悬臂430用于支撑所述升降层板130。直接将支撑座400与升降层板130的侧边固定的连接方式，容易因载重量过大而发生分离，导致升降层板130掉落，相比于该连接方 式，本申请实施例通过在支撑座400上固定设置一个悬臂430，将悬臂430设置于升降层板130的下方，从而通过悬臂430拖着升降层板130，保证升降层板130不会掉落，进一步提升升降层板130的稳定性。
在一些实施方式中，悬臂430可以与升降层板130固定连接，也可以直接将升降层板130放置在悬臂430上，相比于固定连接，直接放置在悬臂430上，有利于升降层板130的拆卸，便于对升降层板130进行清洗以及更换。
本申请实施例提供的悬臂430和支撑座400之间的连接方式不唯一，可以直接通过螺钉等方式固定连接，也可以采用卡扣连接的方式，具体地，如图11所示，所述支撑座400上固定连接有连接板420，所述连接板420上开设有挂孔421，如图10所示，所述悬臂430与所述连接板420连接的一端设置有挂钩431，所述悬臂430上的所述挂钩431钩挂于所述连接板420的所述挂孔421上。相比于螺钉固定的方式，这种挂钩431与挂孔421相互挂接的连接方式，更加便于拆卸，便于用户对悬臂430进行更换。
在一种可能的实施方式中，也可以将挂钩431设置于连接板420上，将挂孔421开设于悬臂430的端部，同样能够实现悬臂430与连接板420之间相互挂接。
在一种可能的实施方式中，连接板420与支撑座400为一体成型结构，从而使连接板420与支撑座400之间的连接更加稳固。
在一种可能的实施方式中，两个所述悬臂430的长度方向均垂直于所述储藏室101的后壁，并且两个所述悬臂430的顶面与所述升降层板130的底面相互贴合，两个所述悬臂430分别固定于所述升降层板130底面的两侧。通过使两个悬臂430的长度方向均垂直于储藏室101的后壁，即两个悬臂430的长度 方向与升降层板130的两侧边沿相互平行设置，从而使两个悬臂430更加稳定的拖住升降层板130，防止升降层板130像前侧或者后侧发生倾斜。
在本申请的一些实施例中，如图4、图5所示，本申请实施例提供的所述驱动电机600设置于电机安装盒610内，所述电机安装盒610固定于所述储藏室101的内壁上，如图15所示，所述电机安装盒610内设置有传动齿轮组620和传动轴630，所述驱动电机600的输出轴与所述传动轴630之间通过所述传动齿轮组620传递扭矩，所述输出轴贯穿所述电机安装盒610、并伸出所述电机安装盒610外，所述牵引绳500与所述输出轴伸出所述电机安装盒610外的部分连接。通过将驱动电机600设置于电机安装盒610内，能够对驱动电机600形成保护并且有利于美观，并且通过传动齿轮组620能够对驱动电机600进行减速，从而将降低后的扭矩传递至传动轴630上，使升降层板130能够缓慢升降，便于用户控制。
为降低驱动电机600占用的储藏室101内部空间，本申请实施例提供的所述储藏室101的内壁上成型有电机安装槽(图中未示出)，所述电机安装盒610固定于所述电机安装槽内。通过在储藏室101后壁上开设电机安装槽，从而将电机安装盒610固定于该电机安装槽内，有效增加储藏室101内部空间。
图14为本申请实施例提供的电机安装盒、线轮以及线轮罩的结构示意图。如图14所示，本申请实施例提供的所述输出轴位于所述电机安装盒610外部的端部上固定有线轮700，所述牵引绳500与所述线轮700固定连接。通过线轮700随输出轴转动，即可对牵引绳500进行收回或者释放，以控制升降层板130上升或者下降。
在一些实施方式中，所述线轮700上沿周向开设有两条凹槽，分别用户容 纳两根牵引绳500，从而防止两根牵引绳500之间发生缠绕，导致线轮700不能正常转动，影响升降层板130正常工作。
在一些实施方式中，如图14所示，在所述线轮700上罩设有线轮罩710，所述线轮罩710与所述电机安装盒610之间通过螺钉连接，所述线轮罩710上开设有用于穿设所述牵引绳500的通孔。所述线轮罩710能够对线轮700以及牵引绳500形成保护，防止线轮700被损坏。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
