Description

Water-saving full-automatic washing machine

Technical Field

The utility model belongs to the technical field of washing machine equipment, and particularly relates to a full-automatic washing machine with a water-saving function.

Background

The washing machine is the most important and common household appliance for washing clothes in daily life, brings great convenience for people to wash the clothes, and is very high in popularization rate at present. However, the generation of new things brings convenience and also generates new problems to be solved. Energy and water conservation is a constant topic in the development process of washing machines, and since people pay attention to environment and resources, people make continuous progress on energy and water conservation technology.

At present, various washing machines are available, such as double-tub, single-tub, drum-type, impeller-type, and ultrasonic washing machines. The full-automatic washing machine becomes a main consumer type in the market due to the advantages of high automation degree and capability of washing large clothes, the double-cylinder impeller type washing machine is relatively lagged behind in technology and difficult to realize automation, but still has certain advantages in the aspects of clothes washing degree, use flexibility and water saving, still occupies certain market, and particularly in certain specific environments and regions with deficient water resources. However, the full-automatic washing machine has the defects of large water consumption and large water consumption per time, and meanwhile, different kinds of clothes such as underwear and coats cannot be washed simultaneously, so that the flexibility is also insufficient, a large amount of water resources are wasted, and the detergent is wasted to a certain extent along with the waste of a large amount of water. Therefore, under many circumstances, two washing machines, namely a double-tub pulsator washing machine and a full-automatic washing machine, are purchased in many families, the full-automatic washing machine is low in use frequency and is mostly used for washing more clothes or large clothes, and the parallel-bar pulsator washing machine is mostly used in other situations.

With the improvement of environmental awareness of enterprises and the public society, washing machine manufacturing enterprises and some people using washing machines actively want to utilize water resources in the washing process so as to save the water resources to the maximum extent. Whether the advantages of the full-automatic washing machine and the dual-washing machine can be combined or not is expected by many people, and the full-automatic washing machine can save time and water and realize full-automatic operation.

Chinese patent No. 200510080133.5 discloses a water-saving washing machine, which comprises a full-automatic washing machine and a washing machine arranged in parallel, and adopts the design of a water pump and a circulating water path, so as to realize the recycling of washing water, rinsing water and dewatering and draining water, and to a certain extent, combine the advantages of the full-automatic washing machine and the double-tub washing machine. However, one water pump can only realize the one-way recycling of the washing water, and an external water pump needs to be added to realize the mutual recycling of the drainage of all links, so that the structure of a circulating water pipeline becomes complicated, the hidden trouble is increased, and the maintenance cost is increased. Secondly, the combination of the full-automatic washing machine and the single-barrel washing machine still needs manual intervention in the washing process, the full-automatic washing machine cannot realize full automation of the process, and the full-automatic washing machine is used as a storage barrel of washing water or rinsing water, a layer of dirt is deposited on the barrel wall after a long time, and the washing is inconvenient, so that the clothes are polluted again when the clothes are washed next time. Secondly, if adopt this design and increase certain type washing machine in parallel again, will lead to circulating water pipeline structure complexity and the operation degree of difficulty greatly increased, expansibility is lower. Meanwhile, the overflow pipe is directly connected with the drainage pipeline, so that clean water can be directly drained under the condition of overflow.

Chinese patent No. 201120515127.9 discloses a full-automatic water-saving washing machine, the design that adopts the combination of two full-automatic washing machines and the design of double pump realize the cyclic utilization of each other of washing drainage, but the design of double pump has increased the trouble hidden danger, secondly first bucket has only designed the water circulation pipeline, do not design direct drainage pipeline, service function is limited to a certain extent, even adopt the pipeline of design directly to discharge, the operation is also more complicated, and do not design filtration system in the water circulation pipeline, there is washing debris to block up the water pump and pollute the hidden danger of second bucket clothing, for example, the button, toilet paper, the end of a thread etc.. Meanwhile, the design of the circulating water path is limited in the combined application of a plurality of full-automatic washing machines, and the expansibility is low.

Therefore, in order to overcome the above disadvantages, it is still necessary to design a washing machine which has a wide application range, is flexible to operate, has a higher degree of automation, and can fully utilize the drainage in the washing, rinsing and dewatering processes to achieve the purposes of saving time, saving water resources and saving detergent.
