一种洗衣机的控制方法及洗衣机Control method of washing machine and washing machine

技术领域Technical field

本发明涉及洗衣机领域，具体是循环节水洗衣机，尤其是一种洗衣机的控制方法及洗衣机。The invention relates to the field of washing machines, in particular to a circulating water-saving washing machine, in particular to a washing machine control method and a washing machine.

背景技术Background technique

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水基本用水量在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 of the rinsing water is about 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。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。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. In order to better save water resources on the basis of the existing laundry methods, many manufacturers have invested a lot of research and development.

现有洗衣机带有循环水功能，其仅仅起到过滤线屑，洗涤均匀或者添加加臭氧、重金属离子杀菌等作用。无法改善耗水量，且对洗净没有根本的提高。The existing washing machine has the function of circulating water, which only functions to filter the wire, wash evenly or add ozone, heavy metal ion sterilization and the like. There is no way to improve water consumption and there is no fundamental improvement in washing.

洗衣水的循环利用，经查阅相关专利文献，如申请号为200810072420.5的“洗衣机循环用水节水装置”，是将洗衣水输入一个水筒内，进行净化处理。该发明对于第一遍的洗衣水不进行净化直接排掉，对于第二、第三遍的漂洗用水进行净化处理之后，要留待下次洗衣时使用。The recycling of the washing water, after consulting the relevant patent documents, such as the application number 200810072420.5 "washing machine circulating water saving device", is to enter the washing water into a water tank for purification treatment. According to the invention, the washing water of the first pass is directly discharged without purification, and after the second and third passes of the rinsing water is purified, it is reserved for use in the next laundry.

还有一种常用的污水处理方法为絮凝处理方法，其采用絮凝剂对污水中所包含的污物进行絮凝处理，使污水中的污物变为絮凝物与水分离开。采用此种污水处理方式，高效、环保、节能、成本低廉。因此，将絮凝处理污水与洗衣机相结合，生成新的循环水洗衣机的方式成为了创新热点。Another commonly used sewage treatment method is a flocculation treatment method, which uses a flocculant to include in the sewage. The dirt is flocculated to cause the dirt in the sewage to become floc and moisture. The sewage treatment method is adopted, which is efficient, environmentally friendly, energy-saving and low in cost. Therefore, the combination of flocculation treated sewage and washing machine to generate a new circulating water washing machine has become a hot spot of innovation.

但是，由于絮凝剂直接投放至洗衣机的盛水筒中对洗涤水进行处理，会导致絮凝剂对衣物的二次污染。另外，洗涤水的容积较大、浊度不一。However, since the flocculant is directly discharged into the water tank of the washing machine to treat the washing water, the flocculant may cause secondary pollution to the laundry. In addition, the volume of the washing water is large and the turbidity is different.

有鉴于此特提出本发明。The present invention has been made in view of the above.
