Description

干衣机 技术领域
本发明涉及一种干衣机，属于干衣机领域。
背景技术
干衣机的大致循环方式为:由电机带动烘干风机旋转,在风扇的作用下，使干衣机内部的空气流动起来在风道中形成气流。常温下的空气经过加热变成相对干燥的高温空气,相对干燥的高温空气在风扇的驱动下进入烘干滚筒后，高温干热的空气接触到湿衣物对湿衣物进行加热，湿衣物中的水分以水蒸汽的形式蒸发析出，此时相对干热的空气迅速吸收衣物表面的水蒸气变为中高温的饱和湿空气，再由风扇的作用把中高温饱和湿空气带离衣物，循环往复直至筒内衣物烘干为止,由此可见空气的有效循环是影响干衣机工作的最主要因素,气流的形成是通过烘干风机的风扇在蜗壳中旋转迫使空气产生流动后进入风路开始循环工作。传统干衣机烘干滚筒、烘干风机的风扇都是单向旋转,所提供的有效气流方向为单一方向,烘干风机的扇叶及蜗壳形状的设计基于渐开线的原则,风扇旋转方向朝接近蜗壳蜗舌方向旋转。由于烘干滚筒单向旋转，使得滚筒内的衣物相互缠绕，无法完全抖散展开，导致烘干效率较低，烘干均匀度未达到理想状态,烘干衣物干燥不均匀。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种干衣机，本发明的第一目的在于提供一种干衣机其烘干滚筒能正反转降低衣物缠绕。本发明的另一目的在于提供一种干衣机，其烘干滚筒正反转的时间相等且正反转两种情况下相等时间内向烘干滚筒内提供的风量相等。本发明的再一目的在于提供一种干衣机，其烘干滚筒正反转的时间不等以适应烘干风机送风。
为解决上述技术问题，本发明采用技术方案的基本构思是：
干衣机，包括烘干滚筒、为烘干滚筒供风的烘干风机，以及驱动烘干滚筒、烘干风机转动的驱动装置，驱动装置、烘干滚筒及烘干风机的风扇均能正反转，或者烘干风机的风扇单向转动。
进一步的，烘干滚筒、烘干风机由同一驱动装置驱动。
进一步的，烘干滚筒、烘干风机由不同的驱动装置驱动。
进一步的，烘干滚筒正反转的时间相等。
进一步的，烘干风机的风扇在正反转两种情况下，相等时间内风扇正转向烘干滚筒内提供的风量与风扇反转向烘干滚筒内提供的风量相等。
进一步的，烘干风机的风扇能正反转，风扇匀速正转，匀速反转。
进一步的，烘干滚筒正反转的时间不相等。
进一步的，烘干风机的风扇能正反转，风扇匀速正转，匀速反转。
进一步的，烘干滚筒正反转的时间比范围为：1:720～720:1。
进一步的，烘干风机的风扇在反转情况下不向烘干滚筒内提供风。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明干衣机，驱动装置、烘干滚筒及烘干风机的风扇均能正反转，由于烘干滚筒能够正反旋转，因此，可以更有效地将烘干滚筒内的衣物抖散，使得烘干更均匀，烘干效率更高。本发明所述的另一种干衣机，其烘干滚筒正反转的时间相等且正反转两种情况下，相等时间内向烘干滚筒内提供的风量相等使得烘干滚筒正反转时均可以进行有效烘干。本发明所述的又一种干衣机，其烘干滚筒正反转的时间不等，通过合理控制烘干滚筒及烘干风机风扇反转时间，以在降低衣物缠绕的情况下使烘干效率最高。
具体实施方式
实施例一
本发明干衣机，包括烘干滚筒、为烘干滚筒供风的烘干风机，以及驱动烘干滚筒、烘干风机转动的驱动装置，驱动装置、烘干滚筒及烘干风机的风扇均能正反转。在其他实施例中，驱动装置和烘干风机的风扇也可单向转动。
在本实施例中，烘干滚筒、烘干风机由同一驱动装置驱动。
此驱动装置为电机，该电机为正反转电机，同时驱动烘干滚筒正反转及驱动烘干风机的风扇正反转，烘干风机的风扇在正反转两种情况下，相等时间内风扇正转向烘干滚筒内提供的风量与风扇反转向烘干滚筒内提供的风量相等，提供的风压也相等。
烘干风机的风扇能正反向旋转，当烘干风机的风扇在正向转动时，转速均匀，在相等时间内其向烘干滚筒内提供的风量相等；烘干风机的风扇在反向转动时转速均匀，在相等时间 内其向烘干滚筒内提供的风量相等。
烘干滚筒正反转的时间比范围为：1:720～720:1。
在本实施例中，烘干滚筒正反转的时间相等。
在其他实施例中，烘干滚筒正反转的时间也可以不相等。
为了使风扇正反转时均可以提供相同的风量和风压，风扇扇叶为直叶片或曲面叶片，烘干风机的风扇与蜗壳同心设置，也可以非同心设置。
烘干风机的蜗壳内腔为对称结构，风扇位于蜗壳内腔且风扇的中心设置于蜗壳内腔的对称轴线上。在其他实施例中，烘干风机的蜗壳内腔也可为非对称结构，
蜗壳的纵截面包括类圆形轮廓，在此类圆形轮廓上设有开口，开口两侧向外各设有一直板，两直板分别与开口两侧的类圆形轮廓相切构成U形轮廓，两直板之间与开口相通形成蜗壳的出风口；风扇位于类圆形轮廓内，在本身实施例中，风扇的中心轴位于类圆形轮廓中心远离出风口的一侧，即风扇与蜗壳费同心设置，蜗壳与风扇之间的间隙自U形轮廓底部向出风口方向逐渐增大，能够形成更好的风压提高循环风流量。
驱动滚筒、烘干风机的驱动装置为同一个电机，降低设备的负载程度及降低能耗。烘干滚筒、烘干风机的风扇均能正反转，由于烘干滚筒能够正反旋转，因此，可以更有效地将烘干滚筒内的衣物抖散，使得烘干更均匀，烘干效率更高。
实施例二
本实施例与实施例一的区别在于：烘干滚筒、烘干风机由不同的驱动装置驱动。
实施例三
本实施例中与实施例一或二的区别在于：
烘干滚筒正反转的时间不相等。烘干风机的风扇在正反转两种情况下，相等时间内风扇正转向烘干滚筒内提供的风量与风扇反转向烘干滚筒内提供的风量相等。
烘干滚筒正反转使得其内部的衣物能抖散，其正反转的时间不相等，以在降低衣物缠绕的情况下提供烘干效率。
实施例四
本实施例与实施例三的区别在于：烘干风机的风扇在反转情况下不向烘干滚筒内提供风。
当风扇的扇叶是曲线状，烘干风机的蜗壳也是渐开线形状时，如果烘干滚筒只朝一个方 向旋转，衣物特别容易缠绕在一起，因此需采用正反转的方式。但因扇叶是渐开线式，只能在风扇正转时有风形成，而在风扇反转时没风，因此，在风扇反转时，加热丝产生的热量无法送至烘干滚筒内，加热丝产生的热量没法对烘干滚筒内的衣物加热，因此，无法产生风的反转时间不能长，否则容易造成烘干时间很长的问题。
在烘干风机的风扇在反转情况下不向烘干滚筒内提供风的情况下，烘干滚筒正反转的时间比范围为：1:720～720:1。
本发明所述的干衣机，其烘干滚筒正反转的时间不等以适应烘干风机送风，通过合理控制烘干滚筒及烘干风机风扇反转时间，以在降低衣物缠绕的情况下使烘干效率最高。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
