Description

一种同时具备制冷制热功能的风扇 技术领域
本发明涉及风扇领域技术，尤其是指一种同时具备制冷制热功能的风扇。
背景技术
风扇通常用于加快自然风的流动速度，加快人体的散热。然而风扇长时间对着人体吹，会增加疲惫感。因此市面上发明了冷气扇，吹出较为柔和的风，并且出风已经通过了降温处理。当冬天到来，人们还希望风扇可以吹出暖气，然而目前市面上的产品均比较单一化，较少能够将制冷、制热和自然风三者结合在一起的设备。变频空调虽然能够同时满足制冷、制热和自然风的供给需求，但是变频空调的主机体积大，变频空调的主机内风道多，结构复杂，制作成本和销售价格均非常高。
发明内容
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种同时具备制冷制热功能的风扇，其制热板和制冷板共用一相同的风道，共用出风口，结构设计合理巧妙，使得风扇整体的体积小，内部结构简化，同时满足制冷、制热和自然风供给需求且成本低，从而克服现有技术的不足。
为实现上述目的，本发明采用如下之技术方案：
一种同时具备制冷制热功能的风扇，包括风扇壳体，该风扇壳体具有进风口、出风口，所述进风口上安装有风机，所述风扇壳体内安装有制热板和制冷板，该制热板枢接于出风口的一侧，该制冷板枢接于出风口的另一侧，该制热板和制冷板共用一个出风口。
作为一种优选方案，所述制热板的一侧设有第一枢接轴，该第一枢接轴的两端伸出制热板以形成第一枢点；所述制冷板的一侧设有第二枢接轴，该第二枢接轴的两端伸出制冷板以形成第二枢点；所述第一枢接轴和第二枢接轴位于出风口的相对两侧。
作为一种优选方案，所述第一枢接轴和第二枢接轴均连接于齿轮传动模组，该齿轮传动模组包括大齿轮、第一小齿轮、第一轴传动齿轮、第二小齿轮、第二轴传动齿轮；所述大齿轮具有扇形齿组，该第一小齿轮和第二小齿轮位于该大齿轮的两侧，扇形齿组周期性与第一小齿轮和第二小齿轮啮合，所述第一轴传动齿轮安装于第一枢接轴并且与第一小齿轮啮合，所述第二轴传动齿轮安装于第二枢接轴并且与第二小齿轮啮合。
作为一种优选方案，所述大齿轮上设置旋钮或者连接电机。
作为一种优选方案，所述风扇壳体的顶部设有两个第一挡台、两个第二挡台；所述制热板打开和关闭该出风口时，该第一轴传动齿轮的两端分别挡止于两个第一挡台；所述制冷板打开和关闭该出风口时，该第二轴传动齿轮的两端分别挡止于两个第二挡台。
作为一种优选方案，所述第一枢接轴连接于第一驱动件上，所述第二枢接轴连接于第二驱动件上，该第一枢接轴和第二枢接轴由两个驱动件分别单独驱动以旋转。
作为一种优选方案，所述第一驱动件和第二驱动件均为驱动电机。
作为一种优选方案，所述第一驱动件和第二驱动件均为拨杆式拨动开关或齿轮式拨动开关。
作为一种优选方案，所述第一驱动件和第二驱动件均为旋钮。
作为一种优选方案，所述制热板是由制热支撑架和绕设于该制热支撑架上的加热丝或PTC制成；所述制冷板是由制冷支撑架和安装于该制冷支撑架上的润湿体制成，该制冷板配设有一水箱，所述水箱设置有小型水泵或电磁阀，所述小型水泵通过水管连通该水箱与润湿体。
本发明与现有技术相比具有明显的优点和有益效果，具体而言，由上述技术方案可知，由于进风口和出风口之间只有一条风道，直接在出风口的一侧枢接制热板，在出风口的另一侧枢接制冷板，这样，制热板和制冷板共用一相同的风道，共用出风口，结构设计合理巧妙，使得风扇整体的体积小，内部结构简化，同时满足制冷、制热和自然风供给需求且成本低。
此外，制热板和制冷板的旋转可以通过共用一组齿轮传动模组，当制热板关闭出风口时，制冷板同时打开出风口，避免干涉。当需要供应自然风时，亦可同时打开制热板和制冷板，齿轮传动模组的连动结构设计巧妙合理，使得风扇的切换方便，且制作成本低。

具体实施方式
实施例一
请参照图1至图5所示，其显示出了本发明之第一实施例的具体结构，是一种同时具备制冷制热功能的风扇，该风扇壳体10具有进风口11、出风口12，所述进风口11上安装有风机20，所述风扇壳体10内安装有制热板30和制冷板40，该制热板30枢接于出风口12的一侧，该制冷板40枢接于出风口12的另一侧，该制热板30和制冷板40共用一个出风口12。藉此，风扇可以处于以下三种状态：制热、制冷、常温送风。1、制热状态时，制热板30完全关闭出风口12，制冷板40旋转到出风口12的侧旁进行让位，此时风机20将自然风抽入至风扇壳体10内部，通过制热板30将空气加热后从制热板30的缝隙中送出暖风。2、制冷状态时，制冷板40完全关闭出风口12，制热板30旋转到出风口12的侧旁进行让位，此时风机20将自然风抽入至风扇壳体10内部，通过制冷板40将空气加湿，使空气降温后从制冷板40的缝隙中送出冷风。3、常温送风时，制冷板40和制热板30均打开该出风口12，二者均旋转让位在出风口12的侧旁，使得出风口12畅通无阻挡，风机20从进风口11送入的自然风直接从该出风口12吹出。
其中，所述制热板30是由制热支撑架31和绕设于该制热支撑架31上的加热丝32或PTC制成。所述制冷板40是由制冷支撑架41和安装于该制冷支撑架41上的润湿体42制成，该制冷板40配设有一水箱43，所述水箱43设置有小型水泵或电磁阀，所述小型水泵通过水管连通该水箱43与润湿体42。例如，润湿体42可以为具有多个镂空孔的纸片。将水箱43安装在风扇壳体10的底部，可以降低整个风扇的重心，使得此产品不易被轻轻碰撞而倒地。
所述制热板30的一侧设有第一枢接轴33，该第一枢接轴33的两端伸出制热板30以形成第一枢点34，所述第一枢点34与风扇壳体10枢接。所述制冷板40的一侧设有第二枢接轴44，该第二枢接轴44的两端伸出制冷板40以形成第二枢点45，所述第二枢点45与风扇壳体10枢接。这种设计，使得制热板30和制冷可以像门一样打开和闭合出风口12。本实施例中，所述第一枢接轴33和第二枢接轴44位于出风口12的相对两侧，例如分别位于左侧和右侧，以及还可以分别位于上侧和下侧。以这种枢接式打开和关闭出风口12的设计方式，可以尽可能地减小风扇的体积，使得风扇可以制作为一个矩形体或立方形结构。
本实施例中，所述第一枢接轴33和第二枢接轴44均连接于齿轮传动模组50，由齿轮传动模组50驱动而连动式打开和关闭该制热板30和制冷板40。所述齿轮传动模组50包括大齿轮51、第一小齿轮52、第一轴传动齿轮53、第二小齿轮54、第二轴传动齿轮55；所述大齿轮51具有扇形齿组511，该第一小齿轮52和第二小齿轮54位于该大齿轮51的两侧，扇形齿组511周期性与第一小齿轮52和第二小齿轮54啮合，所述第一轴传动齿轮53安装于第一枢接轴33并且与第一小齿轮52啮合，所述第二轴传动齿轮55安装于第二枢接轴44并且与第二小齿轮54啮合。设计时，可以将第一轴传动齿轮53、第二轴传动齿轮55均可以用扇形齿轮，可以减小装配时所占用的安装空间，使得风扇可以制作得更小。
藉由将大齿轮51设计为扇形齿组511而非全齿结构，当大齿轮51顺时针旋转时，大齿轮51刚开始与第一小齿轮52啮合，同时便会结束与第二小齿轮54的啮合，此时大齿轮51只能驱动制热板30关闭出风口12，对制冷板40不施力，当大齿轮51顺时针旋转直到转不动时，意味着制热板30已经完全关闭出风口12。当大齿轮51逆时针旋转时，通过第一小齿轮52和第一轴传动齿轮53驱动制热板30旋转，以将出风口12打开，接着大齿轮51与第二小齿轮54啮合，将传动力从第二轴传动齿轮55输送到制冷板40，使制冷板40以同样的方式关闭出风口12。本发明利用齿轮传动模组50的巧妙设计，使得每次只有制热板30和制冷板40关闭出风口12，并且当大齿轮51同时与第一小齿轮52和第二小齿轮54啮合时，出风口12处于贯通的无阻挡状态。
本实施例中，所述大齿轮51上设置旋钮512，通过旋钮512施力控制大齿轮51的顺时针或逆时针旋转。当然，大齿轮51还可以连接电机，利用电机驱动更省力。
如图1和图2所示，所述风扇壳体10的顶部设有两个第一挡台56、两个第二挡台57；所述制热板30打开和关闭该出风口12时，该第一轴传动齿轮53的两端分别挡止于两个第一挡台56；所述制冷板40打开和关闭该出风口12时，该第二轴传动齿轮55的两端分别挡止于两个第二挡台57。此处第一挡台56和第二挡台57的设置通过限制第一轴传动齿轮53和第二轴传动齿轮55的旋转角度，来限制该制热板30和热冷板的旋转角度。
所述风扇壳体10具有上壳体13、下壳体14、后壳体15，该上壳体13罩在下壳体14上包围形成风道，所述后壳体15与下壳体14为一体式结构，所述风机20安装于该后壳体15上。所述进风口11开设于该后壳体15，所述出风口12开设于上壳体13的前面板。
本发明的使用方法如下：
如图3所示，当旋钮512不扭向任何一边时，该大齿轮51同时和第一小齿轮52、第二小齿轮54啮合，制热板30和制冷板40均处于打开状态，出风口12畅通无阻挡，此时可以送出自然风。
如图4所示，当把旋钮512顺时针旋转90度时，该大齿轮51与第一小齿轮52啮合，带动第一小齿轮52旋转，第一小齿轮52带动第一轴传动齿轮53旋转，从而驱动制热板30关闭出风口12，将空气加热再送出。
如图5所示，当把旋钮512逆时针旋转90度时，该大齿轮51与第二小齿轮54啮合，带动第二小齿轮54旋转，第二小齿轮54带动第二轴传动齿轮55旋转，从而驱动制冷板40关闭出风口12，使空气加湿降温再送出。
实施例二
请参照图6所示，其显示出了本发明之第二实施例的具体结构，本实施例的结构与第一实施例基本相同，不同之处在于：所述第一枢接轴33连接于第一驱动件上，所述第二枢接轴44连接于第二驱动件上，该第一枢接轴33和第二枢接轴44由两个驱动件分别单独驱动以旋转，也即是第一枢接轴33和第二枢接轴44二者之间无联动关系。本实施例中，所述第一驱动件和第二驱动件均为驱动电机60。
实施例三
请参照图7所示，其显示出了本发明之第三实施例的具体结构，本实施例的结构与第二实施例基本相同，不同之处在于：所述第一驱动件和第二驱动件均为拨杆式拨动开关70或齿轮式拨动开关70。
实施例四
请参照图8所示，其显示出了本发明之第四实施例的具体结构，本实施例的结构与第二实施例基本相同，不同之处在于：所述第一驱动件和第二驱动件均为旋钮80。
除此之外还可以在风扇上增加喷雾器，起到加湿效果，改善干燥的居住环境。喷雾器可以共用制冷板的水箱43，无需额外增设储水器。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
