具体实施方式
为了解决现有技术中取暖吹风两用风扇结构复杂导致装配繁琐以及控制不稳定导致功能切换不顺畅或坏死的技术问题,本发明采用的主要技术方案为:壳体内设置有支撑发热体支架的滑轨,并且在发热体支架的其中一端设置与发热体支架连接的驱动组件,驱动组件中采用同步电机驱动传动件运动,进而带动发热体支架在滑轨上移动,滑轨的两端分别设置一微动开关,发热体支架移动至滑轨的一端,抵接微动开关,碰触微动开关的按钮时,微动开关被触发,同步电机停止工作;当需要切换功能时,可启动同步电机,使其反方向转动,从而带动发热体支架向滑轨另一端移动,直至抵接另一端的微动开关,触碰该微动开关的按钮,同步电机停止工作。 通过包含有微动开关、同步电机、传动件的驱动组件实现将发热体选择性地移出移进与出风口相对的位置,从而达到选择性地吹出冷风或暖风的目的。
下面结合具体的实施例对本发明的技术方案作详细的描述。
图1和图2所示,分别为本发明实施例涉及冷暖两用风扇的不同方位的立体结构示意图,从图中可以看出,冷暖两用风扇包括壳体1、风道组件100、设置在壳体1上的出风口40。 风道组件100包括设置在壳体1上的风道10、安装在风道10内的风鼓20、与风鼓20同轴连接的用于带动风鼓20转动的电机30。
图3所示为本发明实施例涉及冷暖两用风扇的分解结构示意图,在本实施例中壳体1由上壳体11和下壳体12两个部分组成,风道10设置在上壳体11上,其可以通过螺丝、卡爪等固定在上壳体11上,也可以与上壳体11一体成型。风鼓20安装在风道10内,大致呈圆柱形,圆柱形主体上设置有多个固定的扇叶,用于在风鼓20转动时产生风,风鼓20的两个圆形端面分别设置有延伸而出的可插入风道10的固定孔内的固定轴21和用于与电机30的固定轴31接合的轴孔,风鼓20通过固定轴21安装在风道中后,圆柱形本体可在电机30的驱动下转动。出风口40设置在下壳体12上,为了使风扇整体更加美观,本实施例中还设置有覆盖出风口40的盖板90,盖板90上形成有用于出风的栅格,可以根据客户不同的审美观,将栅格设置为方形或棱形等。
图4所示为本发明实施例涉及冷暖两用风扇隐去部分壳体的结构示意图,结合图3可以看出,壳体1内设置有发热体50以及支撑发热体50的发热体支架60,具体的,固定有发热体50的发热体支架60位于风道10和出风口40之间。发热体50通过支架、螺丝等方式固定在发热体支架60上。发热体支架60还设置有用于覆盖发热体50连接线的发热体压片61,例如将与发热体50连接的电源线覆盖在发热体压片61下面,不至于布线混乱,增加整体结构的整洁性,发热体压片61可通过固定柱固定在发热体支架60上。本实施例中,发热体50优选为PTC发热体,其综合了胶粘和机械式的优点,导热、散热性能优良,效率高,安全可靠;发热体支架60优选为绝缘性能好、不易传导热的材料制成。
壳体1设置有支撑发热体支架60的滑轨70,为了使发热体支架60的移动更加顺畅,本实施中优选在下壳体12的两端分别设置一个滑轨,发热体支架60的底部设置有与滑轨70接合的滑槽,有利于发热体支架60在滑轨70上可靠移动。本实施例中,滑轨70优选为向上延伸的滑动板,结构简单,易于发热体支架60的移动。
发热体支架60的一端设置有与发热体支架60连接的用于使发热体支架60在滑轨70上来回滑动的驱动组件80。为了使风扇的结构更加匀称,本实施例中优选驱动组件80设置在壳体1的与设置有电机30的一端相对的另一端。驱动组件80包括与发热体支架60固定连接的传动件81、与传动件81连接的同步电机82以及至少两个分别设置在滑轨70两端的微动开关83,84。传动件81包括齿条811和与齿条811啮合的齿轮812,齿条811上设置有通孔8111,用于与发热体支架60上突出的定位柱62结合,从而将发热体支架60和齿条811固定连接。齿轮812与设置在下壳体12上的同步电机82同轴连接,优选的,同步电机82固定在下壳体12上的同步电机支架85上。微动开关83,84设置在滑轨70的两端,为了清楚地说明问题,这里将两个微动开关分别表述为第一微动开关83和第二微动开关84,第一微动开关83设置在滑轨70的靠近出风口40的一端,第二微动开关84设置在滑轨70的远离出风口40的一端。
图5所示为微动开关83的结构示意图,下面以微动开关83为例介绍微动开关的工作原理,微动开关83的外部设置有一触动按钮831,当外界触动按下按钮831时,弹簧832被压缩,弹片837向下移动,动触点833与静触点834接合,COM端835与NO端836电路导通,COM端835与NO端836与控制电路连接,从而通过控制电路将同步电机82的电源切断;当松开按钮时,弹簧832在其弹性恢复力作用下恢复原来的状态,动触点833与静触点834脱离,COM端835与NO端836电路断开,从而使同步电机恢复工作。
第一微动开关83的按钮831与第二微动开关84的按钮分别设置在面对发热体支架60的面上,以便与发热体支架60抵接接触。
下面结合图6(a)、图6(b)、图7(a)、图7(b)具体介绍冷暖两用风扇分别出冷风和暖风的过程。
图6(a)所示为本实施例中冷暖两用风扇出冷风时的状态结构示意图,图6(b)所示为图6(a)的剖视图。当用户选择出冷风时,同步电机82接通电源,带动齿轮812旋转,齿轮812旋转时带动与之啮合的齿条811水平移动,具体地说,齿条811沿着远离出风口40的方向移动,由于发热体支架60与齿条811固定连接,因此,齿条811的水平移动可带动发热体支架60沿远离出风口40的方向移动,直至发热体支架60与第二微动开关84抵接接触,触碰到第二微动开关84的按钮,触动第二微动开关84动作,同步电机82停止工作,此时,发热体支架60移出与出风口40相对的位置,偏离出风口40,如图6(b)所示,风鼓20吹出的风不经过发热体50,而是经由风道10直接从出风口40吹出,因此,吹出的是冷风。
图7(a)所示为本实施例中冷暖两用风扇出暖风时的状态结构示意图,图7(b)所示为图7(a)的剖视图。当用户选择出暖风时,同步电机82接通电源,带动齿轮812向与出冷风时相反的方向旋转,齿轮812旋转时带动与之啮合的齿条811向相反方向水平移动,具体地说,齿条811沿着靠近出风口40的方向移动,由于发热体支架60与齿条811固定连接,因此,齿条811的水平移动可带动发热体支架60沿靠近出风口40的方向移动,直至发热体支架60与第一微动开关83抵接接触,触碰到第一微动开关83的按钮831,触动第一微动开关83动作,同步电机82停止工作,此时,发热体支架60恰好位于与出风口40相对的位置,如图7(b)所示,风鼓20吹出的风从风道10经由发热体50从出风口40吹出,因此,吹出的是暖风。
可见,采用同步电机82及连动件81控制发热体支架60的移动,并通过微动开关检测发热体支架60的位置,控制同步电机82的运行,可以使固定在发热体支架60上的发热体50选择性地位于正对出风口40的位置,即当风扇出冷风时,发热体50远离正对出风口40的位置设置,当风扇出暖风时,发热体50正对出风口40的位置设置, 能够以简单的结构实现风扇可选择的吹出冷风或暖风的目的,微动开关的按断力小,通断迅速,因此对同步电机的控制相当灵敏,提高了冷暖两用风扇的使用性能,从而解决了现有技术中取暖吹风两用风扇结构复杂导致装配繁琐以及控制不稳定导致功能切换不顺畅或坏死的技术问题。
本领域技术人员应理解,以上仅为本发明最优的实施例,可以根据上述说明加以改进或变换,例如,上述传动件并不限定为齿轮和齿条的形式,可以用蜗杆和蜗轮替换。在没有做出创造性劳动的前提下做出的改进和变换都应属于本发明所附权利要求的保护范围。
