Description

干衣设备风道结构及干衣设备 技术领域
本公开涉及干衣技术领域，例如涉及一种干衣设备风道结构及干衣设备。
背景技术
相关技术中的干衣机或洗干一体机的进风口和加热装置之间由进风风道连接，冷空气经过加热装置加热后通过进风风道进入滚筒内。目前的干衣机和洗干一体机的内部设置当中，为了提高干衣速度，多数通过提高加热装置的功率而完成，但是，加热装置的功率提高后，会造成滚筒进风口的温度偏高，影响设备的正常运行。此外，传统的风道结构设计会导致滚筒进风口温度分布不均匀，造成烘干效率差，甚至因为局部的高温导致衣物受损。
在解决进风口温度偏高的问题上，本领域的技术人员往往会通过加大进风量或者在进风口外开设额外的冷风进口来应对，但是对干衣机或洗干一体机来说，结构尺寸方面限制较多，风扇的功率通常已经达到该干衣机或洗干一体机机型的极限，无法再提供额外的进风量，而从冷风进口进入的外界冷风随环境温度的变化，不容易控制。
