通 it*脱水过程中中先控制内筒以较^ 4度旋转并循环喷淋,可使内 筒中的水能够充分渗透至衣物, 然后高速旋转进行排水, 更容易去除衣物 上的水溶性物质 (如残留的洗涤剂或污垢)和小分子颗粒。
进水和循环喷淋可同时进行, 也可进水完成后再进行循环喷淋。
进水后, 可首先控制内筒以第一转速旋转, 在旋转的过程中, 洗衣机 内筒中的水風出至 7^ 环通道中并经由喷淋头喷淋至内筒中。
本实施例中, 内筒在每次喷淋流程中以第一转速旋转的时长(即该预 设时长)为 1-5分钟。
循环喷淋完成后, 关闭 7^ 环通道, 使内筒继续旋转, 并控制内筒保 持循环喷淋时的转速旋转或者以更高的转速旋转,以将内筒旋转时甩出的 水排出洗衣机外。
具体地, 内筒在喷淋流程中的第一转速为每分钟 400-1000转, 内筒 在脱水流程中的第二转速为每分钟 400-1400转。
