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。但该等实施方式并不限制本发明,本领域的普通技术人员根据该等实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
接下来以水为冷媒介质为例进行举例说明,当然其它如酒精或者盐水等在满足应用要求的前提下也可以作为冷媒介质。
本发明方案中,作为模块化设计的底座单元1000,其在整体上位于整个冷风扇产品的地步,用于承载其余的各个部件,也就是说,其余的部分,如前面板单元2000或者制冷单元3000或者送风单元4000或者外罩单元6000或者冷媒单元5000等功能结构,作为模块化设计的单元结构时,可以通过包括插口/插销/滑轨/滑槽之间的插拔式连接、螺丝/螺栓/螺孔/螺母之间的连接等组装连接的方式组织到该底座单元1000上。
在本发明的桌面冷风扇的技术方案中,其整机采用全模块设计时,其表面部分(这里的表面包括上部表面即底座1010在最下方的以外的部分,当然还包括为满足部分单元如外罩单元6000的安装而可以被涉及的部分底面部分)至少被划分为了用于可拆卸地安装前面板单元2000、制冷单元3000、送风单元4000、外罩单元6000、冷媒单元5000的前面板单元安装部、制冷单元安装部、送风单元安装部、外罩单元安装部、冷媒单元安装部,在底座1010上这些单元被一一对应地组装到相应的安装部位置。
在本发明方案中,如图所示,制冷单元3000、送风单元4000以及冷媒单元5000在整体上可以位于底座1010的上表面部分,也就是制冷单元安装部、送风单元安装部以及冷媒单元安装部可以形成于底座1010的上部,如这些都可以设置于底座1010的上表面部分或者至少位于上表面的上方部分,这是为了便于安装设置。而同时,底座1010的前部可以设置前面板单元安装部用于在竖向安装设置前面板单元2000,在图中,前面板单元2000的前面板由上而下地安装设置到底座1010上。此外,在底座1010的底部或者靠近底部的侧边位置还可以设置外罩单元安装部,用于安装设置外罩单元6000。当然外罩单元6000的外罩6010其前端部分与前面板2030相邻的部分也设置有与该前面板2030相配合的结构,如与前面板2030边沿相配合的卡槽,而提高前面板2030与外罩6010以及底座1010的安装连接牢固性。
在上述方案中,制冷单元3000、送风单元4000以及冷媒单元5000等与底座1010之间的连接可以采用卡合连接的方式,即采用至少两个相互之间配合且彼此卡合的结构进行连接、限制或者固定,如采用榫卯结构、卡槽卡销结构等。还可以采用匹配咬合的螺纹结构件进行连接、限制或者固定,如采用具有外螺纹的螺钉通过外罩6010具有的通孔并连接到具有螺孔的底座1010等。包括而不限于连接方式适合于制冷单元3000、送风单元4000、冷媒单元5000、前面板单元2000以及外罩单元6000与底座单元1000之间的连接,只要能够满足各单 元的整体组装与连接即可。
在上述方案中,作为又一种改进,为了将底座1010划分为水路区域1090和风道区域1080,底座1010上还可以实现两者分隔的隔板结构1020,该隔板结构1020设置于两个区域的邻接位置,是一种从底座1010相应位置向底座1010外侧凸出的连续结构,当然为了将水路区域1090与风道区域1080分隔开,该连续结构在安装状态下与底座1010表面接合处是处于密闭隔离状态的,这就能够起到有效地将水路区域1090的范围限定在相应区域,而在使用过程中不至于发生外流,如进入风道区域1080而影响使用或者安全运行。当然这种隔板结构1020可以为向底座1010外侧凸出的在竖向(这里指垂直于底座1010表面)的直板结构,如图7中所示;也可以为向底座1010外侧凸出的在竖向(这里指垂直于底座1010表面)的弯曲结构;只要能够在水路区域1090周边形成完整的封闭结构即可,即形成一个容纳冷媒介质的容器5010形区域即可。
在上述方案中,底座1010上还具有用于支撑底座1010的支脚或者垫脚结构,其可以设置于与各单元安装部相对的一侧或者设置于底座1010侧部,也就是底座1010的底部或者底面或者周边的外侧或者内侧,用于起到支撑底座1010或者整个风扇的作用。
将上述底座单元1000的技术方案应用于桌面冷风扇,其可以表现为包括而不限于如下的技术方案:
如图1所示,整个桌面冷风扇,其整体可以包括如下几个可以独立拆卸和安装的部分:
底座单元1000,具体如图11所示,在本实施例方案中,其是在整个冷水扇中起到连接作用的基础结构(也就是其余功能单元都会与该底座单元1000发生功能性的连接或者联系),其余的功能结构单元都可以被安装设置于该结构上或者与该结构发生联系。在底座1010上,向底座1010外凸出的隔板结构1020将该底座1010分隔为水路区域1090和风道区域1080,该隔板结构1020与相邻位置的底座1010边沿凸起共同形成了用于在使用过程中收集由湿帘3021滴落的冷媒介质的空间,同时该空间还用于容纳向湿帘3021输送冷媒介质的泵,冷媒介质由泵经过送液管输送至竖向设置的湿帘3021上部,浸润湿帘3021,多余的介质则回流到该空间中而实现循环使用。
由此考虑到冷媒介质的输送以及循环利用,可以知道,该水路区域1090至少与制冷单元3000以及冷媒单元5000发生联系。也就是说在不考虑用额外的管路将该水路区域1090与制冷单元3000与冷媒单元5000进行连接的情况下,制冷单元3000和冷媒单元5000应当被设置于于该水路区域1090,也就是如图1、3、4、5、7等所示的情形。
在此情形下,当制冷单元3000设置于直接设置于水路区域1090上方也就是制冷单元3000形成于制冷单元安装部时,用于承载湿帘3021的湿帘支架3010,将其承载的湿帘3021安置于制冷单元安装部。为了承载湿帘3021,该湿帘支架3010可以为主体上具有湿帘3021安装位的框架结构,在湿帘3021安装位周边,也就是四周的位置具有支架结构,从而可以使该湿帘3021舒展且平稳地支撑于该湿帘支架3010上。该湿帘支架3010其下端部形成有若干个卡口,与该卡口 对应的,则是在制冷单元安装部上设置的若干个卡突件1021,也就是在对应位置的底座1010上设置如图所的由底座1010外壁向外侧凸出的卡突件1021,在安装时,卡口卡设到该卡突件1021上形成卡接结构,以对湿帘支架3010形成限制和固定。当然为了获得更好的固定效率,该湿帘支架3010的底部还可以设置有螺纹连接用的螺孔,并且在对应的制冷单元安装部设置有对应的螺接部,从而还可以通过螺钉穿过该螺孔而将其湿帘支架3010进一步地固定在底座1010上,以获得更好的结构稳定性。
当然为了获得更好的湿帘3021安装性能,湿帘3021在加载到湿帘支架3010上前,还可以先将其安装到湿帘固定架3022上,如图中的湿帘固定架3022从湿帘3021下端撑托湿帘3021,而使其湿帘3021的下端被限定到湿帘固定架3022内,从而至少便于湿帘3021的安装固定工作。当然,在湿帘固定架3022底部同样可以设置有与卡突件1021配合的固定卡口3023,该固定卡口3023在图1中展示为一种由湿帘固定架3022的固定架底座边沿向底座1010方向凸出的部分上,该固定卡口3023可以为形成在该固定架底座上的一种镂空缺口结构,而该镂空缺口结构是与卡突件1021相配合的,也就是在两者配合时卡突件1021被嵌入到固定卡口3023的镂空中而形成了一种限定;也可以设置于螺接部对应的通孔,从而对该湿帘固定架3022也可以通过卡接或者螺接的方式进行固定。
在上述方案的基础上,关于设置于底座1010前部的前面板单元2000,其具有前面板2030,并且如图1所示,该前面板2030的下端,特别是其边沿位置设置有用于安装连接到底座1010上的凸沿,该凸沿向底座1010方向凸出。并且对应地在底座1010的前部也就是对应的前面板安装部设置有对应于该凸沿的凸沿槽,在图中可以看出,该凸沿槽是形成于底座1010边沿的阶梯槽。在安装时,该向底座1010凸出的凸沿恰当地匹配连接到该凸沿槽内,从而形成一定程度的锁紧和限制,使该前面板被安装固定到底座1010上。当然这里前面板的连接和固定同样还可以采用类似如前陈述的卡接结构或者螺纹连接结构以固定或者连接。当然在图1中,对应于该底座1010上方的前面板空缺的部分,也同样可以具有相应的凸沿结构,并配合对应位置的外罩6010上的凸沿槽结构,通过三者之间的连接,以将该冷风扇在外部整体上形成一个有效的整体连接结构,当然在与底座1010获得稳固连接的前提下这种额外的连接是非必要的。
此外考虑到满足用户通过USB接口对手机等移动设备的充电需求,可以在前面板2030上设置USB接口2031,该接口与电源进线连接,从而有该电源对其进行供电,以在用户使用时满足对手机等设备的充电需求。这里的电源一般指具有变压、整流等功能从而满足向USB接口供电,并进行输出,如将220V/50Hz市电转换为5V直流充电电压由该USB接口2031输出。
同时还可以在前面板2030上设置控制键2032,为了配合该控制键2032的操作,在前面板2030背面对应位置还设置印刷有控制电路的PCB板,在控制电路上连接有与控制键2032配合的开关(这里的开关可以是按钮形式的机械开关,也可以为感应式的);同时在该控制电路上还连接有PLC等,可以用于依据开关指令而控制输送泵、贯流风机等的工作状态。
当然在本方案中,前面板其主体上还设置有贯通该面板的外出风口2010, 如图2所示,该外出风口2010用于在使用中供送风单元4000吹出的凉风吹出该冷风扇,而向机外供冷。
为了能够调整外出风口2010吹出的凉风的出风方向,该该前面板上的外出风口2010上还设置有调向机构,该调向机构可以包括用于在竖向调整供风方向的横摆叶2011;也可以包括用于在横向调整供风方向的竖摆叶2020;这种调整出风方向的摆叶可以同时存在,也可以选择其单一,而只在单一方向调整供风方向。如图1所示,则为具有横向调整出风方向的情形,其中,横摆叶2011由上而下可以设置有多个横摆叶2011单元,每个单元在其前后两侧中的一侧的端部为端轴,其用于活动连接到外出风口2010边沿位置上对应的端轴枢;此外,在每个单元上与端轴所在侧相对的另一侧,则连接有活动端轴,该每个单元活动端轴均用于活动连接到同一个限定条,该限定条上具有与活动端部相配合的活动端孔,活动端轴于活动端孔内能够转动。为了能够实现横摆叶2011在竖向调整风向,该横摆叶2011其上还可以连接有横拨片2012,该横拨片2012可以为连接到某一个横摆叶2011单元上,如图中所示的情形,也可以为连接到限定条上。在竖直方向波动横拨片2012时,该横摆叶2011单元会以其一侧的端轴为轴发生偏转,另一侧则牵引限定条使该出风口上的横摆叶2011所有的横摆叶2011单元发生从动,而实现在竖向调整出风方向。
同样地,竖摆叶2020由左而右可以设置有多个竖摆叶单元,每个单元在其前后两侧中的一侧的端部为竖端轴,其用于活动连接到外出风口2010边沿位置上对应的竖端轴枢。此外,为了额外地提供调整横向出风方向,该竖摆叶2020上同样还可以设置横向出风调向结构,即包括:在每个单元上与竖端轴所在侧相对的另一侧,则还可以连接有竖活动端轴,该每个单元的竖活动端轴均用于活动连接到同一个横限定条,该横限定条上具有与竖活动端部相配合的活动端孔,活动端轴于活动端孔内能够转动。为了能够实现竖摆叶2020在横向调整风向,该竖摆叶2020其上还可以连接有竖拨片,该竖拨片可以为连接到某一个竖摆叶单元上,如图中所示的情形,也可以为连接到横限定条上。在横向波动竖拨片时,该竖摆叶单元会以其一侧的端轴为轴发生偏转,另一侧则牵引横限定条使该外出风口2010上的竖摆叶2020所有的竖摆叶单元发生从动,而实现在横向调整出风方向。
在上述方案的基础上,关于从上部向下覆盖地设置在底座1010上部的外罩单元6000,其主要包括外罩6010,外罩6010具有一对相对的面(面Ⅰ和面Ⅱ)、顶面以及与前面板相对的右侧面,此时由于底座1010的存在,该外罩6010的底座1010可以设置也可以不设置,图中则为不设置底面的情形,在这里,如图1中所示的情形,外罩6010至少在其相对的面的下端具有向内侧弯折的折边,通过该折边将外罩6010固定的底座1010上,可以看到该折边上可以形成有连接孔,通过该连接孔可以通过螺丝或者与该连接孔相配合的卡块将该折边限定到底座1010上;当然在底座1010上也还可以形成开口朝向底座1010外侧并且沿所在底座1010侧延伸而与折边相配合的折边槽,通过将折边在折边槽内沿该折边槽移动,从而将外罩6010组装到底座1010上。外罩6010的面Ⅰ与制冷单元3000的湿帘3021相邻,故而为了满足凉风的供应要求,该冷风扇的进风口 6011设置在面Ⅰ上,以使工作时,机外的空气由进风口6011进入机内,而经过湿帘3021与其上的冷媒介质换热形成冷风,再经过风道结构4020,由前面板上的出风口吹出,而向外供冷。
额外地,在外罩6010或者底座1010等与桌面或者地面接触的部分,还可以设置若干脚垫7000,以起到防磨损的作用。
额外地,如图1、图6和图10所示,本方案的冷媒单元5000的容器5010还可以被支撑在壳体外侧,此时在壳体上可以形成用于限定该容器5010的容器5010限定位,图中,该容器5010限定位形成于与前面板相对的壳体的边沿位置,对应地在底座1010上的冷媒单元安装部也形成于相应的边沿位置。在图中所展示的具有L形的容器5010限定位,该限定位包括了靠近边沿的部分顶面,该部分顶面平行地下沉了若干深度,同时也包括了部分向方向前面板方向平移若干距离的位于上部的部分右侧边即侧边Ⅰ。这里顶面下沉的部分以及右侧边平移的部分,各自下沉或者平移的尺寸可以在同方向上与容器5010的尺寸相配合,此时容器5010在整体上也形成了一个近似方形的结构。
为了将该容器5010限制到壳体上,其右侧边平移的侧边Ⅰ上还形成有至少向容器5010突出一个滑轨结构6021或者向壳体凹陷的轨道结构5031,与之相对应的,则在容器5010的相邻侧壁上形成有匹配的向容器5010凹陷的轨道结构5031或者向壳体突出的滑轨结构6021;在图8和图10中则展示了侧边Ⅰ上形成有一对沿竖向设置的向容器5010突出的滑轨结构6021以及在容器5010的相邻侧壁伤形成有向容器5010凹陷的轨道结构5031的情形,从图中可以看到,这里的滑轨结构6021的主体在垂直于延长方向的截面结构在总体上为“┏”形,故而轨道结构5031也是与之相匹配的凹陷形状。当然我们应当知道的是,这里滑轨结构6021或者轨道结构5031的设置方向(无论是横向、竖向或者倾斜设置)、设置数量(无论是设置一组或者更多组)、设置位置(无论是设置与边缘或者中心或者其他位置)以及设置的截面结构(无论是设置成三角楔形等)等并无特别的限定,只要满足提供该滑轨结构6021和轨道结构5031的配合而实现容器5010与壳体的连接和限定即可。
当然为了向湿帘3021输送冷媒介质,也就是满足向底座1010上水路区域1090内输送冷媒介质。容器5010上还设置有单向阀5020,用于在工作状态下连通容器5010与水路区域1090,也就是底座1010上形成的下储液箱,进而提供设置于下储液箱内的输送泵3033经由输送管3032向湿帘3021输送冷媒介质。如图3所示,展示了容器5010底部设置的单向阀5020的一种情形,该单向阀5020包括内封件5021、T形件5022以及复位弹簧5023,T形件5022包括连接杆以及形成于连接杆一端的限位件Ⅰ,T形件5022的连接杆贯穿地连接在出液口,限位件Ⅰ与内封件5021分别置于出液口两侧;复位弹簧5023套设在连接杆位于出液口外侧的的部分,限位件Ⅰ的尺寸大于复位弹簧5023的内径并且限制该复位弹簧5023于连接杆上,并且该单向阀5020上的复位弹簧5023始终处于受压缩的状态(即复位弹簧5023的放松状态的长度大于连接杆在出液口外侧的最大长度);内封件5021限制于连接杆的另一端,该内封件5021由容器5010内侧与出液口贴合时对出液口形成密封。对应地,则在下储液箱内还设置有压 顶件1031,单向阀5020通过对应于压顶件1031的接液口6012,也就是设置于压顶件1031上方的接液口6012,单向阀5020由该接液口6012进入下储液箱内(当然此时外罩6010上对应的位置还应当设置有供对接用的外罩6010接口,该结构至少由单向阀5020进入下储液箱时穿过),压顶件1031对应于单向阀5020的连接杆一端设置,以使其在工作状态时压顶件1031的上端对该连接杆一端形成抵触并使复位弹簧5023压缩而将内封件5021离开出液口(也就是使内封件5021不与出液口密封,而使冷媒介质可以流动)。
为了更好实现冷媒介质在湿帘3021上的分布,也就是起到最好的冷风供应和制冷效果,输送管3032向湿帘3021上输送的冷媒介质是通过分布器实现分布的,这里的分布器关联到湿帘架上的存储池3013。也就是说分布器可以为在存储池3013的底部向湿帘延伸出若干根导流管从而在存储池上形成有满足要求的分布器。在图13a、13b中展示了输送管3032通过进水管3011向存储池3013输送冷媒介质(可以是水)的情形。
同时还可以在存储池3013中设置液位开关3012,以对存储池中的液位状态进行监控,这里监控的液位反应了输送泵1011向存储池中输送冷媒介质的工作状态是否正常,此时,当液位开关3012在连续时段(可以是1分钟内)采集到的液位信号都是低于警戒水平的,则可以表明下储液箱中的冷媒介质的储量不足或者冷媒介质在容器5010、下储液箱以及存储池之间的流转管路出现了故障,需要补充冷媒介质或者进行检修,此时即可以发出警告信号,如激发前面板上的信号灯或者蜂鸣器等。
液位开关可以为浮球式液位开关或压力式液位开关或电容式液位开关或电子式液位开关。在图13a、13b中展示了一种浮球式液位开关的应用,该浮球式液位开关包括了浮子30121、连接到浮子的顶杆30122以及触发开关30123,浮子的平均密度是低于冷媒介质的,这就使得浮子可以随着存储池中的液位的涨落而上浮或下降。这里的触发开关30123在液位较高,而浮子30121处于上浮状态,而被顶杆30122抵触时,触发开关30123处于休眠状态,由于触发开关30123是连接在信号灯或蜂鸣器等的工作电路上的,此时信号灯或者蜂鸣器等休眠,不发出需要补充冷媒介质或者检修的信号。反之,则浮子下落,顶杆30122脱离触发开关30123,触发开关被激活,激发信号灯或蜂鸣器的工作。同理的,压力式液位开关或电容式液位开关或电子式液位开关同样是为了获取液位信息而做出类似的操作。
为了使经过湿帘后的冷媒介质安全高效地返回到下储液箱,在湿帘下方的湿帘架上还形成有回流池,用于在工作中承接有湿帘回流的冷媒介质,在回流池的底部设置有回流装置,同时在储液盒盖上对应地配合设置有回流限定装置,两者之间形成有供冷媒介质由回流池流向下储液箱的通路,在工作状态下这条通路时畅通的。而为了防止在暂停工作进行搬运移动等状态或者倾斜状态下,下储液箱中的冷媒介质由该通道反流至回流池而存在溢出的风险,回流限定装置被设置为在这种状态下是阻碍反流发生的。
如图14a-c展示了回流限定装置的一种情形:回流限定装置包括有形成于储液盒盖上的对接口1112、连接到该对接口1112的对接管1113以及连接到该 对接管的十字槽硅胶件1111,该十字槽硅胶件1111上形成有十字刻痕11110,该对接口1112是与回流装置上的回流接口配合的,两者之间采用密封件密封。在十字槽硅胶件1111在未受到外力状态下式保持十字刻痕11110闭合的,此时十字槽硅胶件1111处于封闭状态,从而使对接管1113在十字槽硅胶件1111上部形成有封闭空间。从而,在工作状态时,经过湿帘回流至回流池的冷媒介质,汇集到十字槽硅胶件1111上部,从而通过重力打开十字刻痕11110而使其处于打开的开口形态111101,此时冷媒介质顺利地返回至下储液箱。而在停止工作后,汇集到十字槽硅胶件1111上部的冷媒介质得不到补充,而无法形成使十字刻痕11110打开成开口状态111101的重力,十字刻痕11110恢复为闭合状态,从而可以阻止冷媒介质由下储液箱经过对接口1112反流。
如图15a-c展示了回流限定装置的又以在情形:回流限定装置包括有形成于储液盒盖上的对接口1112、连接到该对接口1112的对接管1113以及设置在该对接管中的浮球1114,该浮球1114的平均密度低于冷媒介质的密度,该对接口1112是与回流装置上的回流接口配合的,两者之间采用密封件密封,浮球1114的尺寸是与对接口1112的内径或对接管1113位于浮球1114上部的部分内径相配合的,这就形成了适合于浮球的封堵位,也就是浮球1114在移动至相应位置时能够对其进行封堵。从而,在工作状态时,经过湿帘回流至回流池的冷媒介质,汇集到浮球1114上部,对浮球形成冲击,并且由于输送泵不断地将下储液箱中的冷媒介质不断地输送至存储池中,下储液箱中的液位必然处于较低的状态,此时浮球必然也处于较低位置而脱离封堵位,此时冷媒介质顺利地返回至下储液箱。而在停止工作后,汇集到下储液箱中的冷媒介质不断提高其中的液位,而提升浮球的位置直至到达封堵位,切断对接口1112与回流装置上的回流接口之间的连通,从而可以阻止冷媒介质由下储液箱经过对接口1112反流。
当然在工作状态下,当设备发生倾斜是,同样会由于位置倾斜导致冷媒介质汇聚,而提升浮球实现封堵,同样起到防止冷媒介质反流外溢的情形。
当然,为了实现供冷送风,在机体内还应当设置送风用的送风单元4000,该送风单元4000包括由电机驱动的风机结构以及风道结构4020,其中风机结构采用由电机驱动的贯流风机4010,该贯流风机4010竖向设置在底座1010的送风单元4000内,也就是贯流风机4010的旋转轴竖直于底座1010,该贯流风机4010其旋转轴的下端部具有支持该贯流风机4010旋转的旋转支持机构,该旋转支持机构可以为沿旋转轴向下方延伸凸出的下转轴,或者为在旋转轴方向上向贯流风机4010内凹陷形成的内凹的下转轴;与这里的下转轴对应的,则需要在底座1010的送风单元安装部对应地形成有支持该下转轴并与之匹配的下转轴托,该下转轴托与贯流风机4010的旋转轴同轴设置,故而必然与下转轴同轴设置,对应于向下方延伸凸出的下转轴则其匹配的下转轴托其与该下转轴的连接部则应当为凹陷的,这种凹陷结构可以为向底座1010凹陷的凹槽形的下转轴托,也可以为与之匹配的轴承的内圈,该内圈连接到凸出的下转轴托上,而外圈固定到底座1010上等这些技术方案及其类似技术方案均可适用;而当下转轴为内凹的结构时,位于底座1010则对应地设置有与该内凹结构对应的凸出的下转轴托,同样的该下转轴托可以直接配合地形成于凹槽形的下转轴内以支持其旋转,当 然也可以采用下转轴托与轴承内圈连接,外圈固定于凹槽形的下转轴内等这些技术方案及其类似技术方案均可适用。
在上述设置中,用于驱动贯流风机4010绕轴旋转的电机位于贯流风机4010的上方,其从贯流风机4010的上部驱动贯流风机4010的旋转,此时电机自身其可以限制于对应的外罩6010内侧或者风道机构或者湿帘3021架等其它可以充当固定的临近结构上,以满足驱动旋转的要求。当然这里的电机可以采用罩极电机4030,以谋求更低的工作噪音和更稳定的运行等,当然其它类型的电机也是可以支持的。
此外,风道结构4020其形成有容纳贯流风机4010并且供气流在冷风扇机内流动的结构,其毫无疑问地具有与湿帘3021相邻的进风口6011、用于向外界输出冷风的出风口以及连接进风口6011和出风口并用于调整机内风向的风道,该出风口与前面板上的外出风口2010相连通,用于向机外排风,贯流风机4010被容纳于进风口6011和出风口之间的风道内。
如图1、图3-6展示了一种送风单元4000的实施方式,其中贯流风机4010具有沿旋转轴向下方延伸凸出的下转轴,由该下转轴被支持地连接到底座1010内,并且罩极电机4030的输出端连接到该罩极电机4030的旋转轴的上方,罩极电机4030并且被限制到风道结构4020上,由此在工作时,即可有罩极电机4030驱动该贯流风机4010绕旋转轴旋转,而有外罩6010上的进风口6011进风,通过湿帘3021与其上的冷媒介质换热,并经过风道结构4020再由前面板的外出风口2010出风。
本发明方案的冷风扇,其安装连接状态如图1-12所示,在工作时,电机由贯流风机4010上去驱动其旋转,该旋转发生在风道结构4020的风道内,外进风口6011发生进气;装有冷媒介质如水的容器5010被安装到安装位上,其下方的单向阀5020顶触到底座1010上的压顶件1031,此时复位弹簧5023被压缩,连接杆受力向上移动,由内部封住出液口的限位件Ⅰ松开,而打开出液口,冷媒介质流出,并经由接液口6012进入底座1010上的下储液箱内;工作状态下,下储液箱中的输送泵3033工作并将冷媒介质经由输送管3032输送至存储池并经分布器分配至湿帘3021将其浸润;气流经过湿帘3021进行换热,发生冷却并成为冷风后,进入风道转向,最后由前面板上的外出风口2010吹出机外。经过湿帘的冷媒介质在脱离湿帘后,汇集到回流池,并经由相互配合的回流装置以及回流限定装置返回到下储液箱。通过调整外出风口2010的摆叶方向可以自行调整供风方向,比如上下拨动横拨片2012从而实现风向在竖向的变动。在工作状态下当存储池中的液位开关检测中其中的液位不符合预设时,则触发警报,提醒补液或者设备维护。而当对设备进行移动或者发生倾斜时,则有回流限定装置切断回流池与下储液箱之间的反流通道,从而形成安全防护。
外罩6010上开有进风格栅,形成进风口6011,前面板上开有出风口,出风口设置有横叶片和竖叶片用来调节出风方向。
贯流风轮系统竖直的安装在底盘上。罩极电机4030设置在风道顶部,如果机器倾斜,底盘内的水不能撒到电机上,确保整机安全。
外罩6010的进风格栅部位设置有筋条,湿帘3021纸下水支架安装在底盘 上,与外罩6010的筋条形成导轨,内部设置有湿帘3021纸。进风口6011设置在整机的最右侧,出风口根据风道和整机尺寸尽量靠近整机左侧安装,尽量使进风口6011和出风口距离比较远,避免回风,影响整机制冷效率。(如果出风口和进风口6011比较近,由整机出风口吹出的风,就会被风轮由进风口6011再次吸进风轮,形成短路,也就是回风,影响整机效率)
机器出风口成喇叭状设计,增大出风口,可以有效增加风量。
水箱设置在整机后侧。外罩6010上设置有轨道和水箱上设置有轨道,水箱安装在外罩6010的后侧,通过轨道的配合用于安装和取出,水箱和外罩6010通过轨道配合安装,水箱向上移动取出水箱。
底盘内设置有隔板特征,将底盘分为两个区域,一个区域为风轮风道安装区域,另一个区域为水路区域1090,湿帘3021纸支架和水箱安装在水路区域1090的上方。
水箱安装在机器上时,水箱控制阀们被底盘上设置的顶柱顶开,水箱控制阀门打开,水箱内部的水经过阀门向下流入底盘的水路区域1090,(当水路区域1090的水位达到水平面的高度时,阀门被水平面关闭,不再向下流水,当水位低于水平面以后,水箱内部的水再次向下流水)再经过水路区域1090内部设置的水泵,将水抽到湿帘3021纸支架的上接水盒,节水盒内向下设置有向下流水的开口,水再经过开口向下流向安装在湿帘3021纸支架内部的湿帘3021纸,水经过湿帘3021纸再向下流向底盘的水路区域1090。
如图1,介绍了本机所包含的整机零部件。
如图2:外罩上开有进风格栅,形成进风口,前面板上开有出风口,出风口设置有横叶片和竖叶片用来调节出风方向,前面板上有控制键和USB充电口,可对手机进行充电。
如图3:贯流风轮系统竖直的安装在底盘上。罩极电机设置在风道顶部,如果机器倾斜,底盘内的水不能撒到电机上,确保整机安全。
如图4、图5:外罩的进风格栅部位设置有筋条,湿帘纸下水支架安装在底盘上,与外罩的筋条形成导轨,内部设置有湿帘纸。进风口设置在整机的最右侧,出风口根据风道和整机尺寸尽量靠近整机左侧安装,尽量使进风口和出风口距离比较远,避免回风,影响整机制冷效率。(如果出风口和进风口比较近,由整机出风口吹出的风,就会被风轮由进风口再次吸进风轮,形成短路,也就是回风,影响整机效率)
如图5:机器出风口成喇叭状设计,增大出风口,可以有效增加风量。
如图1:整机采用灌流风轮和罩极电机设计,首先贯流风轮噪音比较小,罩极电机转速高、噪音小、成本低。电机的高转速,为风轮提供动力,使整机具有较大风量和风速,而且整机噪音要比采用离心风轮和轴流风轮的机器声音小。
如图4:水箱设置在整机后侧,
如图9和图8:外罩上设置有轨道和水箱上设置有轨道,水箱安装在外罩的后侧,通过轨道和的配合用于安装和取出。
如图6,水箱和外罩通过轨道配合安装,如图10,水箱向上移动取出水箱。
如图11和图12,底盘内设置有隔板特征,将底盘分为两个区域,一个区域 为风轮风道安装区域,另一个区域为水路区域(储水盒),湿帘纸支架和水箱安装在水路区域的上方(如图4和图7)。
如图3:水箱安装在机器上时,水箱控制阀们被底盘上设置的顶柱顶开,水箱控制阀门打开,水箱内部的水经过阀门向下流入底盘的水路区域,(当水路区域的水位达到水平面的高度时,阀门被水平面关闭,不再向下流水,当水位低于水平面以后,水箱内部的水再次向下流水)再经过水路区域内部设置的水泵,将水抽到湿帘纸支架的上接水盒,节水盒内向下设置有向下流水的开口,水再经过开口向下流向安装在湿帘纸支架内部的湿帘纸,水经过湿帘纸再向下流向底盘的水路区域。
如图13a-b,下水盒内有低水位开关,可及时提醒加水,确保客户的制冷舒适性。水箱水足够时,浮子上浮,机组正常运行,当水箱水和储水盒中水用完的时候,水泵抽不到水,浮子无法上浮,低水位开关动作,产生嗡鸣声提醒客户加水;
如图14a-c和图15a-c,储水盒的两个安装方案。底盘内的水路区域在开机运行时是一个开放区域,可正常走水,在停机时是一个封闭区域,防止搬运移动时机组大角度倾斜导致漏水。
