Description
本发明属于衣物处理设备的技术领域,具体涉及一种洗衣机的添加剂投放装置,还涉及一种安装有上述添加剂投放装置的洗衣机。The present invention belongs to the technical field of clothing treatment equipment, and specifically relates to an additive dispensing device for a washing machine, and also relates to a washing machine equipped with the above additive dispensing device.
现有的洗衣机一般设有供洗涤水盛放的盛水筒,盛水筒内设置可旋转的洗涤筒,洗涤筒上开设连通内外的脱水孔,使得流入盛水筒内的洗涤水可利用脱水孔在洗涤筒内外进行交互流动,以实现洗涤水与洗涤筒内投放的待处理负载相接触、利用洗涤水对负载进行处理的效果。Existing washing machines are generally equipped with a water tank for holding wash water. A rotatable washing drum is provided in the water tank. A dehydration hole is provided on the washing drum that connects the inside and outside of the washing tank, so that the washing water flowing into the water tank can be used for washing through the dehydration hole. There is an interactive flow inside and outside the drum to achieve the effect of the washing water being in contact with the load to be processed placed in the washing drum and using the washing water to process the load.
上述现有洗衣机的添加剂投放方式如下:通过添加剂投放装置,将添加剂投放到与洗衣机盛水筒相连通的管路中,然后投放的添加剂沿管路流入洗衣机盛水筒中。因此,现有方式所投放的添加剂是处于洗衣机的盛水筒内、洗涤筒外,而无法直接与洗涤筒内投放的负载相接触。The additive delivery method of the above-mentioned existing washing machine is as follows: through the additive delivery device, the additive is delivered into the pipeline connected to the water tank of the washing machine, and then the added additive flows into the water tank of the washing machine along the pipeline. Therefore, the additives placed in the existing method are placed in the water tank of the washing machine and outside the washing tub, and cannot directly contact the load placed in the washing tub.
然后,在洗衣机执行洗涤程序时,投放的添加剂与流入盛水筒内的洗涤水相混合,部分混合有添加剂的洗涤水经脱水孔流入洗涤筒中、与筒内待处理负载相接触,才能使得混入洗涤水中的一小部分添加剂与负载相接触、对负载产生作用。因此,传统的添加剂投放方式存在投放的添加剂使用效率低、添加剂浪费的问题。Then, when the washing machine executes the washing program, the added additives are mixed with the washing water flowing into the water tank. Part of the washing water mixed with additives flows into the washing drum through the dewatering hole and comes into contact with the load to be processed in the drum, so that it can be mixed into the washing machine. A small portion of the additive in the water comes into contact with the load and acts on it. Therefore, the traditional method of adding additives has the problems of low efficiency and waste of additives.
同时,传统的添加剂投放方式中,为了保证投放至盛水筒与洗涤筒之间的添加剂与洗涤筒内待处理负载相接触,需要向盛水筒内流入大量的水,直至盛水筒内洗涤水的水位高于洗涤筒后,才能保证洗涤水经脱水孔流入洗涤筒内、添加剂与洗涤筒内负载相接触的目的。因此,传统的添加剂投放方式还存在,添加剂投放用水过多的问题。At the same time, in the traditional way of adding additives, in order to ensure that the additives placed between the water tank and the washing drum are in contact with the load to be processed in the washing drum, a large amount of water needs to be flowed into the water tank until the water level of the wash water in the water tank reaches the level of the water tank. Only when it is higher than the washing drum can the washing water flow into the washing drum through the dewatering hole and the additives be in contact with the load in the washing drum. Therefore, the traditional way of adding additives still has the problem of too much water for adding additives.
为了解决上述问题,申请人之前提出了一种直接向洗衣机筒内投放添加剂混合液,利用添加剂混合液直接作用与筒内衣物上,并利用洗衣机对被混合液浸湿的、添加剂浓度较高的衣物进行高效洗涤处理的技术方案。In order to solve the above problems, the applicant has previously proposed a method of directly putting an additive mixture into the drum of the washing machine, using the additive mixture to directly act on the clothes in the drum, and using the washing machine to wet the clothes with a high additive concentration that are soaked by the mixture. Technical solution for efficient washing of clothes.
但是,上述方案,存在添加剂与进水在投放装置内混合效果较差,投放至筒内的混合液均匀度很低,筒内衣物与添加剂无法充分混合,存在洗涤后的衣物洁净度较差的问题;还有,由于添加剂与进水直接在投放装置的上盖内所设集成水路内进行混合,使得集成水路内部会因抽吸作用而形成较大的负压,容易造成上盖内水路被破坏、造成进水泄露等问题。However, with the above scheme, the mixing effect of the additives and the incoming water in the feeding device is poor, the uniformity of the mixed liquid put into the cylinder is very low, the clothes in the cylinder cannot be fully mixed with the additives, and the cleanliness of the washed clothes is poor. Problem; also, since the additives and incoming water are mixed directly in the integrated waterway set in the upper cover of the delivery device, a large negative pressure will be formed inside the integrated waterway due to the suction effect, which can easily cause the waterway in the upper cover to be blocked. damage, causing water leakage and other problems.
有鉴于此,特提出本发明。In view of this, the present invention is proposed.
