Description
本发明涉及洗衣机领域，尤其涉及一种絮凝洗衣机，特别涉及一种清洁絮凝桶的控制方法。The invention relates to the field of washing machines, in particular to a flocculation washing machine, in particular to a control method for cleaning a flocculation bucket.
随着人们生活水平的提高，洗衣机现已成为人们日常生活的主要家电之一，洗衣机的洗衣过程主要包括洗涤、漂洗、甩干几个阶段，在洗涤阶段洗衣机进水和洗涤剂对衣物进行洗涤，进入漂洗阶段后为了漂净污渍和残留的洗涤剂，需要进更多的水或执行更多的漂洗次数对衣物进行漂洗，这势必耗费大量的水资源，即使是省水的滚筒洗衣机，为了漂净衣物也需要漂洗至少两次，这一过程至少要消耗30L以上的自来水。有时衣物上的污渍较少或投放的洗涤剂较少，可能两次就漂洗干净了，但由于用户选择了3次漂洗，势必也会造成水资源的浪费，比如6Kg的全自动洗衣机一般两次漂洗基本用水量在100升左右。如何在洗净衣服的同时能够做到省水省电，一直是消费者关注的焦点之一。With the improvement of people's living standards, washing machines have become one of the main household appliances in daily life. The washing process of washing machines mainly includes several stages of washing, rinsing and drying. In the washing stage, washing machine water and detergent wash clothes. In order to rinse off the stains and residual detergent after entering the rinsing stage, it is necessary to take more water or perform more rinsing times to rinse the clothes, which will inevitably consume a lot of water resources, even if it is a water-saving drum washing machine, Rinsing clothes also needs to be rinsed at least twice, and this process consumes at least 30L of tap water. Sometimes the clothes have less stains or less detergent, and may be rinsed twice. However, because the user chooses 3 rinses, it will inevitably cause waste of water resources. For example, 6Kg automatic washing machine is generally used twice. The basic water consumption for rinsing is around 100 liters. How to save water and electricity while washing clothes has always been one of the focuses of consumers.
目前为止尚未有家用洗衣机配套使用的水净化及循环利用装置，即便是所谓的带有节水功能的洗衣机，一般在洗衣机的侧位安装储水箱，采用水泵进行注水和排水，一般能够一次注水，漂洗3次，起到节水功能。但洗涤后的水不能够保存，同时使洗衣机本身结构复杂、庞大，不利于运输、回收处理等。由于体积、结构以及灵活性等方面的限制，影响了洗衣机原有功能以及节水箱本身功能的充分发挥。So far, there is no water purification and recycling device for household washing machines. Even the so-called washing machine with water-saving function generally installs a water storage tank on the side of the washing machine, and uses a water pump for water injection and drainage, and generally can inject water once. Rinse 3 times to save water. However, the washed water cannot be preserved, and the structure of the washing machine itself is complicated and large, which is not conducive to transportation, recycling and the like. Due to limitations in size, structure and flexibility, the original function of the washing machine and the function of the water-saving tank itself are fully exerted.
在现有洗衣方式的基础上为了更好的节约水资源，很多厂家投入了大量的研发，以生产具有水净化及循环利用装置，生产带有节水功能的洗衣机。On the basis of the existing laundry method, in order to better save water resources, many manufacturers have invested a lot of research and development to produce water purification and recycling devices to produce washing machines with water-saving functions.
同时，随着絮凝技术逐渐成熟，在工业领域中逐渐应用和推广开来。采用絮凝原理制作的节水洗衣机也就成为了各洗衣机生产厂家的研发热点。但是，由于现有的絮凝桶对洗涤水或漂洗水进行絮凝处理时，水中的污物与絮凝剂会反应产生絮凝物。由于在絮凝剂中添加有高分子聚合物，絮凝物的粘附性很强，容易附着在絮凝桶的内壁上。絮凝反应后，会有部分絮凝物留存在絮凝桶中，滋生大量细菌，对洗
涤衣物造成二次污染。At the same time, as the flocculation technology matures, it is gradually applied and promoted in the industrial field. The water-saving washing machine made by the flocculation principle has become a research and development hotspot of each washing machine manufacturer. However, since the existing flocculation tank flocculates the washing water or the rinsing water, the dirt in the water reacts with the flocculating agent to generate flocs. Since the high molecular weight polymer is added to the flocculant, the floc has strong adhesion and is liable to adhere to the inner wall of the flocculation bucket. After the flocculation reaction, some floc will remain in the flocculation bucket, breeding a large number of bacteria, washing
Distressed clothing causes secondary pollution.
尤其是为了更好的分离絮体和清水，一般通过絮凝剂、结构及絮凝***的优化，使得絮体漂浮在最上层。在最后一次排水中，絮体依然会浮在水的上层，在水排空后，大量絮体落在了絮凝筒底，容易滋生细菌，对洗涤衣物造成二次污染。Especially for better separation of flocs and clean water, flocculation is generally optimized by flocculating agent, structure and flocculation system, so that the flocs float in the uppermost layer. In the last drainage, the flocs will still float on the upper layer of the water. After the water is drained, a large number of flocs fall on the bottom of the flocculation cylinder, which is easy to breed bacteria and cause secondary pollution to the laundry.
有鉴于此特提出本发明。The present invention has been made in view of the above.

The washing machine structure includes an outer tub, an inner tub and a door body disposed in the outer tub 1 . The control panel, the water inlet system and the washing motor, the water inlet system includes an inlet structure and a detergent delivery device 5. The outer tub 1 is a receiving structure for accommodating washing water, and the inner tub provided in the outer tub 1 is a laundry structure; preferably, as shown in FIG. 1, the washing machine structure may further include a pulsator provided in the inner tub. The outer tub 1 is in communication with the water inlet structure to feed the washing machine.
本发明实施例所述的循环水处理装置至少包括絮凝处理单元；絮凝处理单元，包括与外桶1连通的絮凝桶2和向絮凝桶2内投放絮凝剂的絮凝剂投放装置6，由外桶1排水至絮凝桶2内絮凝处理。The circulating water treatment device according to the embodiment of the present invention includes at least a flocculation processing unit; the flocculation processing unit includes a flocculation tank 2 communicating with the outer tub 1 and a flocculant placing device 6 for discharging a flocculating agent into the flocculation tank 2, which is provided by the outer tub 1 Drainage to the flocculation tank 2 within the flocculation treatment.
如图1所示，所述的絮凝桶2设有进水口、回水口和排污口；外桶1的出水口经设有第一水泵的第一管路8与絮凝桶2的进水口15相连通，絮凝桶2的回水口经设有第二水泵的第二管路与外桶1的进水口相连通，以形成洗涤水在外桶1与絮凝桶2之间的可控循环回路。所述絮凝桶2的排污口经设有排水阀的排水管10与洗衣机外部相连通，将洗涤完成后的污水及絮凝物外排。还可以，将排污口设于外桶1的底部，使得外排水自外桶1经排污口、排水阀后流出洗衣机。As shown in FIG. 1, the flocculation tank 2 is provided with a water inlet, a water return port and a sewage outlet; the water outlet of the outer tank 1 is connected to the water inlet 15 of the flocculation tank 2 via a first line 8 provided with a first water pump.

It is also possible to provide the sewage outlet at the bottom of the outer tub 1 so that the outer drainage water flows out of the washing machine from the outer tub 1 through the drain outlet and the drain valve.
优选的，循环水处理装置还可以包括一过滤单元7；过滤单元7，将经絮凝处理单元处理后的絮凝处理水进行过滤处理，以分离絮凝物和洁净水。而为了实现对絮凝物和洁净水的分离还可以不采用过滤装置，例如：在絮凝桶中设置水位传感器，使得絮凝桶中的液面始终保持一定高度，以使得漂浮在絮凝桶水面处的絮凝物始终留存在絮凝桶中，也达到了去除絮凝水中絮凝物的目的。Preferably, the circulating water treatment device may further include a filtering unit 7; the filtering unit 7 filters the flocculated water treated by the flocculation processing unit to separate the flocs and the clean water. In order to achieve the separation of the floc and the clean water, the filtering device may not be used.

清水进行一次或多次冲刷，该絮凝物依然上浮在水面，在冲刷水带动一小部分絮凝物排至絮凝桶外后，依然会有大量絮凝物落在絮凝桶底部。However, regardless of which of the above separation methods is used, the flocculation barrel wall retains a strong adherent floc; if the floc adheres to the side wall of the flocculation barrel for a long time, a large amount of bacteria is generated in the flocculation barrel. Especially after the water is drained, the floating flocs are not washed by water, and will fall on the bottom of the flocculation bucket. Even if using
The clean water is washed one or more times, and the floc still floats on the surface of the water. After the flushing water drives a small amount of floc to drain outside the flocculation bucket, a large amount of floc will still fall on the bottom of the flocculation bucket.
因此，为了解决上述问题，本发明特提出了，在絮凝桶2中设置喷洗结构，使得水流经喷洗结构对絮凝桶2内壁进行冲洗，以使得残留在絮凝桶2中的絮凝物被循环冲洗水彻底冲走，实现对絮凝桶进行清洗的目的。Therefore, in order to solve the above problems, the present invention specifically proposes that a spray structure is disposed in the flocculation tank 2 such that water flows through the spray structure to flush the inner wall of the flocculation tank 2, so that the floc remaining in the flocculation tank 2 is circulated. The flushing water is completely washed away to achieve the purpose of cleaning the flocculation bucket.
同时，在絮凝桶2外设置外循环管3，外循环管3的一端与絮凝桶2底部相连通、另一端与喷洗结构相连通；外循环管3上设有循环泵4，使得絮凝桶2中的水经外循环管3实现自下向上的循环流动，并利用循环水流为喷洗结构供水，以对絮凝桶2内壁进行冲洗，将附着于絮凝桶2内壁上、尤其是落在絮凝桶2桶底部上的絮凝物去除。At the same time, an outer circulation pipe 3 is disposed outside the flocculation drum 2, one end of the outer circulation pipe 3 is connected with the bottom of the flocculation tank 2, and the other end is connected with the spray washing structure; the outer circulation pipe 3 is provided with a circulation pump 4, so that the flocculation bucket The water in 2 is circulated from bottom to top through the outer circulation pipe 3, and the circulating water flow is used to supply water to the spray structure to wash the inner wall of the flocculation tank 2, and will adhere to the inner wall of the flocculation tank 2, especially to flocculate.
