下面结合附图对本发明的较佳实施例进行详细阐述,以使本发明的优点和特征能更易于被本领域技术人员理解,从而对本发明的保护范围做出更为清楚明确的界定。
本发明中的术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
本发明主要涉及一种制冷设备,本实施例的制冷设备以冰箱为例来说明。
结合图1和图2所示,冰箱包括制冷间室、给制冷间室提供冷量的制冷系统、将制冷系统产生的冷量输送至所述制冷间室的风道组件1以及控制所述冰箱运行的控制器。对于风冷式的冰箱,冰箱的箱体内胆限定有储物间室。储物间室的后侧设置有风道组件1,其内具有用于将冷却空气输送至储物间室内的风道2。
在本实施例中,风道组件1包括具有出风口的风道盖板3、设置于风道盖板3一侧的风道泡沫4以及可转动地固定在风道盖板3上的风门5。其中,风道盖板3和风门5均为注塑件,便于与风道泡沫4配合安装。
风道盖板3的部分突伸入风道泡沫4内,以与风道泡沫4共同限定出与出风口连通的风道2,风道2用于将冷却空气输送至储物间室内,储物间室可以设置为冷藏抽屉等。
结合图3至图6所示,风门5包括设置于风道2内的风门扇叶51、风门扇叶51向风道盖板3外壁方向延伸并突出于风道盖板3外壁的旋转连接柱52以及过盈套设于旋转连接柱52外周的控风旋钮55。通过手动调节控风旋钮55带动风门扇叶51旋转,具有调节方式简单的优点。
其中,风道2包括风道盖板3限定出的圆弧段风道23,圆弧段风道23的一侧壁与风门扇叶51转动抵接,也就是说,圆弧段风道23的一侧壁的中心与风门扇叶51的中心重合,使得风门扇叶51与圆弧段风道23的一侧壁之间没有间隙。风门5盖板上设置了风门5,避免了风道泡沫4漏风或风道泡沫4的部件偏移导致控风不精确的问题。
进一步地,圆弧段风道23的另一侧壁的中心与风门扇叶51的旋转中心预设有偏移,以使得风门扇叶51在转动的过程中与圆弧段风道23的另一侧壁之间形成不同大小的通风截面。当风门扇叶51在旋转的过程中,使得风门扇叶51与圆弧段风道23的另一侧壁之间的间距发生渐变,使得通道内的出风量发生渐变,从而控制储物间室的温度。
具体的,圆弧段风道23的另一侧壁的中心与风门扇叶51的旋转中心预设有偏移,换句话说,圆弧段风道23的另一侧壁的中心与风门扇叶51的中心不重合,当然,圆弧段风道23的另一侧壁的中心可以在风门扇叶51的中心的下方或者上方。
本实施例中,圆弧段风道23的另一侧壁的中心在风门扇叶51的中心的上方,也就是说,风门扇叶51更靠近圆弧段风道23的另一侧壁的下部,当风门扇叶51逆时针转动时,风门扇叶51与圆弧段风道23的另一侧壁之间的间距会越来越大,从而增大风道2的通风量,反之,风门 扇叶51顺时针转动,风门扇叶51与圆弧段风道23的另一侧壁之间的间距会越来越小,从而减少风道2的通风量。
为了更简单的实现调节风门扇叶51与圆弧段风道23的另一侧壁之间的间距,风门扇叶51包括呈圆柱状的柱状本体511、柱状本体511的外壁向外延伸形成的延伸板512,其中,风道盖板3设置有限制延伸板512转动角度的限位结构,限位结构包括第一限位结构、第二限位结构,延伸板512在第一限位结构与第二限位结构之间转动。
优选地,风道盖板3包括风道盖板本体31、风道盖板本体31向风道泡沫4内延伸的侧板部32,侧板部32包括相对设置的第一侧板部33和第二侧板部34,其中,第一侧板部33和第二侧板部34共同限定出圆弧段风道23,第一侧板部33与风门扇叶51转动抵接,可以理解的是,第二侧板部34包括前文所述的圆弧段风道23的另一侧壁。
进一步地限定第一侧板部33的结构,第一侧板部33包括与柱状本体511转动抵接的圆弧抵接段331、分别与圆弧抵接段331邻接的过渡段332、设置于过渡段332边缘的边缘段333,优选的,过渡段332设为斜面段,边缘段333设为竖直段。
具体地,风道盖板本体31向圆弧段风道23内凸设有凸柱35形成第一限位结构,其中,远离凸柱35的过渡段332形成第二限位结构。由于前文所述,风门扇叶51更靠近圆弧段风道23的另一侧壁的下部,也就是说,凸柱35较第二限位结构更靠近圆弧段风道23的另一侧壁的下部设置,具有限位简单、便于实现的优点。
具体地,凸柱35靠近圆弧段风道23的另一侧壁的底部边沿处设置, 当延伸板512与凸柱35相抵接接触时,风门扇叶51与圆弧段风道23的另一侧壁之间的间距是处于最小值状态,从而风道2的通风量也是处于最小值状态,当延伸板512与过渡段332相抵接接触时,风门扇叶51与圆弧段风道23的另一侧壁之间的间距处于最大值状态,从而风道2的通风量也是处于最大值状态。
进一步地限定圆弧段风道23的结构,圆弧段风道23的另一侧壁呈半圆形设置,又由于第一侧板部33和第二侧板部34之间间隔设置,那就使得,风门扇叶51的转动角度大于180°,优选的,风门扇叶51的最大转动角度设为210°~240°,可以多档位、精细的调节通道的出风量。
为了实现风道盖板3与风门5可转动地固定的关系,风门5还包括柱状本体511向风道盖板3外壁方向延伸形成的多个卡扣部53,其中,风道盖板3开设有供柱状本体511贯穿的贯穿孔36,贯穿孔36的内壁向内延伸形成环状凸台37,环状凸台37卡设于卡扣部53与柱状本体511之间,具有连接方式简单的优点。
优选地,旋转连接柱52由柱状本体511的中心向风道盖板3外壁方向延伸形成,控风旋钮55开设有与所述旋转连接柱52过盈配合的安装孔。
为了更方便的限位调节风门扇叶51的转动,风道盖板3还设置有限制控风旋钮55转动形成的止挡凸起54,同理,控风旋钮55的内壁设置有与止挡凸起54配合的呈圆弧状的止挡配合部551。
为了增强结构的密封性,风门5还包括与侧板部32可拆卸连接的 风门密封盖板56,风门密封盖板56包括盖设于第一侧板部33和第二侧板部34之间的第一盖板561、卡设于侧板部32与风道泡沫4之间的第二盖板562以及设置于侧板部32的端部并突伸入风道泡沫4内的入口导引板563。
其中,第二盖板562垂直连接于第一盖板561,侧板部32向外延伸有卡块321与第二盖板562卡合连接,第二盖板562开设有与卡块321配合的通孔564。
优选地,入口导引板563的靠近风道泡沫4的端部呈渐扩态势,便于冷却空气的进入。
优选地,风道2包括风道泡沫4限定的主风道21、主风道21向一侧分流并向下延伸形成的风道支路22,其中,风门5设置于风道支路22上,主风道21的进风口211设置于风道泡沫4的下部、出风口30设置于风道支路22的出口端,通过这样的设置,主风道21形成自下而上的风路,使得在输送冷却空气的过程中,冷却空气所带的水分在重力作用下向下流动,不会通过风道支路22流进风门5内,形成一种自动排水结构。
结合图7所示,风道泡沫4包括与风道盖板3可拆卸连接的第一风道泡沫41、设置于第一风道泡沫41背离风道盖板3一侧的风道密封贴43,其中,风道盖板3的边缘设置有多个定位结构38,第一风道泡沫41设置有与定位结构38相配合的配合结构42,第一风道泡沫41与风道密封贴43之间形成主风道21。
优选地,定位结构38包括多个用于卡住风道泡沫4的卡勾,当然, 其他用于两个结构之间的定位配合结构都可以应用于本实施例中,由于两者的定位配合关系不是本发明主要要解决的问题,这里不作详述。
相较于现有技术,本发明提供的风道组件1通过风门扇叶51与圆弧段风道23的一侧壁转动抵接,使得风门扇叶51与圆弧段风道23的一侧壁之间没有间隙,圆弧段风道23的另一侧壁的中心与所述风门扇叶51的旋转中心预设有偏移,当风门扇叶51在旋转时,风门扇叶51与圆弧段风道23的另一侧壁之间的间距会随之发生变化,转到不同角度,形成的通风截面大小也不同,从而调节风道2的通风量,实现对出风口30出风量多档位的精确控制,同时风门5与风道盖板3转动连接,连接方式简单易于实现,具有结构简单、控风精准的优点。
最后说明的是,以上实施例仅用以说明本发明的技术方案而非限制,尽管通过上述优选实施例已经对本发明进行了详细的描述,但本领域技术人员应当理解,可以在形式上和细节上对其做出各种各样的改变,而不偏离本发明权利要求书所限定的范围。
