现有的具有衣物洗涤功能的衣物处理设备大体上可分为波轮式、搅拌式及滚筒式。但无论上述哪种形式的衣物处理设备在对衣物进行洗涤处理时,都是通过水和洗涤剂的作用去除洗涤物的污渍,以实现衣物进行洗涤的效果。Existing laundry treatment equipment with a laundry washing function can be roughly classified into a pulsator type, a stirring type and a drum type. However, no matter which type of the above-mentioned laundry treatment equipment is used for washing the laundry, the stains of the laundry are removed by the action of water and detergent, so as to achieve the effect of washing the laundry.
在滚筒式衣物处理设备中,一般具有壳体,内部安装有用于容纳洗涤水的外筒,在外筒的内侧设置有用于容纳洗涤物的滚筒,在外筒的背面设置有用于旋转上述滚筒的电机和轴。In the drum type laundry treatment equipment, there is generally a casing, an outer tub for accommodating washing water is installed inside, a drum for accommodating the laundry is disposed inside the outer tub, and a motor for rotating the drum and a motor for rotating the drum are disposed on the back of the outer tub. axis.
上述现有的滚筒式衣物处理设备,在执行洗涤程序时,洗涤水会在滚筒和外筒之间交叉流动,会导致滚筒外部、外筒内部之间普遍留存有大量污垢,为了避免上述污垢对洗涤水的污染,申请人之前就提出了一种将内外筒合二为一的无孔滚筒衣物处理设备,以克服滚筒和外筒之间留存污垢的问题。上述无孔滚筒衣物处理设备在执行排水时,是利用滚筒旋转离心力驱动排水口处的阀体打开,令滚筒内的洗涤水自排水口流出,流出的排水水流流至集水容器中进行收集,再经与集水容器相连的排水管外排出衣物处理设备。In the above-mentioned existing drum-type laundry treatment equipment, when the washing procedure is performed, the washing water will cross-flow between the drum and the outer cylinder, which will generally cause a large amount of dirt to remain between the outside of the drum and the interior of the outer cylinder. For the pollution of washing water, the applicant has previously proposed a non-porous drum laundry treatment device that combines an inner and outer drum into one, so as to overcome the problem of dirt remaining between the drum and the outer drum. When the above-mentioned non-porous drum clothes treatment equipment performs drainage, it uses the centrifugal force of drum rotation to drive the valve body at the drainage outlet to open, so that the washing water in the drum flows out from the drainage outlet, and the outflowing drainage water flows into the water collection container for collection. Then, the clothes treatment equipment is discharged out of the drain pipe connected with the water collection container.
但是,上述的无孔滚筒衣物处理设备的滚筒排水口处设置的阀体普遍是在滚筒转动至同一设定值后,同时打开、或闭合排水口,这就存在如下问题:However, the valve body set at the drum drain port of the above-mentioned non-porous drum clothes treatment equipment generally opens or closes the drain port after the drum rotates to the same set value, which has the following problems:
在衣物处理设备排水过程中、尤其是排水程序初期,衣物处理设备容易因排水过急而导致集水槽内水位过高等情况的发生,甚至会导致排水水流外溢至衣物处理设备外部的问题;During the drainage process of the clothes treatment equipment, especially in the early stage of the drainage process, the clothes treatment equipment is prone to excessively high water level in the sump due to the rapid drainage, and even causes the drainage water to overflow to the outside of the clothes treatment equipment;
还有,在衣物处理设备的排水后期,由于滚筒内残存的洗涤水量不大、使排水流速变小,但此时为保证排水口的打开,还需驱动滚筒以较高转速旋转,增大了衣物处理设备的工作能耗。In addition, in the later stage of the drainage of the clothes treatment equipment, due to the small amount of washing water remaining in the drum, the drainage flow rate becomes smaller, but at this time, in order to ensure the opening of the drainage port, it is necessary to drive the drum to rotate at a higher speed, which increases the The operating energy consumption of the laundry treatment equipment.
有鉴于此,特提出本发明。In view of this, the present invention is proposed.
