Abstract

The utility model provides a cycle water-saving washing machine which can reuse the rinsing water of the washing machine. The technical solution adopted is: a circulating water-saving washing machine, including a washing machine shell, a washing bucket installed in the shell, and a drainpipe connected to the washing bucket. The water inlet of the washing machine or directly into the washing tub. The utility model has simple structure, can be directly improved on the existing washing machine, and has low cost. When in use, if the washing water discharged in the first pass is dirty, it will be directly discharged out of the washing machine through the washing machine. If it is not too dirty, it can also be rinsed and cycled. The final membrane backwash water is also directly discharged. Compared with the existing method of using water in this way, the washing machine can save 50%-60% of water for washing clothes, effectively saves water resources, and has high social benefits.

Description

A cycle water-saving washing machine

technical field

The utility model relates to a household appliance, in particular to a circulating water-saving washing machine which can fully utilize water resources.

Background technique

In the existing washing machine, the water inlet pipe and the water outlet pipe are generally connected in the washing bucket, and the water is discharged in each process of the washing and dehydration process of the clothes, and the water is not reused, resulting in a waste of resources, especially This is especially true for fully automatic washing machines. This type of washing machine is used in urban households, and the waste is particularly serious, and it is also not suitable for use in water-deficient areas or areas where water is inconvenient. There have been some technologies to transform the washing machine, such as setting a water storage tank inside or outside the washing machine, storing and sedimenting the water discharged from the washing machine, and then using it, mopping the floor, cleaning the toilet, etc., but due to the limitation of the water storage space limitations and are not well utilized.

Contents of the invention

The technical problem to be solved by the utility model is to provide a circulating water-saving washing machine which can reuse the rinsing water of the washing machine.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a circulating water-saving washing machine, including a washing machine shell, a washing bucket installed in the shell, and a drainpipe connected to the washing bucket, and the outlet of the drainpipe is connected to a circulating filter. system, the outlet of the circulating filtration system is connected to the water inlet of the washing machine or directly into the washing tub.

The lower end of the drainage pipe is connected with a drainage valve, and the water inlet of the circulation filtration system is connected with the outlet of the drainage pipe. The circulation filtration system includes a circulation pump, a reversing valve connected in series with it, and an ultrafiltration membrane connected with the reversing valve; One end of the water pipe I is connected to the upper end of the ultrafiltration membrane, and the other end is connected to the washing bucket. One end of the backwash drain pipe is also connected to the upper end of the ultrafiltration membrane, and the other end is connected to the lower end of the drain valve.

As an improvement to the above technical solution, a sterilizer is installed in front of the circulating filtration system.

The utility model has simple structure, can be directly improved on the existing washing machine, and has low cost. When in use, if the first washing water is dirty, it will be directly discharged out of the washing machine through the drain valve of the washing machine. If it is not too dirty, it can directly enter the filter and rinse cycle. Finally, the filtered clean water in the washing bucket is used for backwashing of the ultrafiltration membrane and then discharged directly. Compared with the existing method, the water consumption of the washing machine improved in this way can save 50%-60% of water for washing clothes, effectively saves water resources, and has high social benefits.

Detailed ways

The structural principle of the present utility model is specifically described below in conjunction with the accompanying drawings: when in use, if the washing water discharged for the first time is dirty, it will be directly discharged outside the machine through the washing machine drain valve 4 (if it is not too dirty, it can be directly filtered and rinsed. ). When the washing machine enters the rinsing program, the secondary water intake reaches the set water level, the washing machine controller gives a start signal and delays the start of the circulation pump 5, and the rinsing water passes through the circulation filter system, that is, first passes through the circulation pump 5--reversing valve 7 --The circulating water pipe 8 passes through the ultrafiltration membrane 13, and after passing through the ultrafiltration membrane 13, the rinsing water becomes reusable clean water, and then re-enters the washing bucket 2 of the washing machine through the circulating water pipe I9, and the washing bucket 2 continues to work, so that the circulation is filtered , until the rinse water is clear and the clothes are rinsed clean. At the end of the rinsing program, the reversing valve 7 in the circulating filtration system is reversed, and the water for the last rinsing is passed through the backwashing water inlet pipe 10 and the ultrafiltration membrane 13 for backwashing of the ultrafiltration membrane, and then the backwashing water passes through the backwashing water. The washing drain pipe 12 is directly discharged, and the washing machine enters the next spin-drying program. In the rinsing program, design each filtration cycle for two to five minutes.

The utility model is not only applicable to the washing machine, but all those that use the circulating filter system to change the dirty water into clean water and re-enter the original device for reuse are all within the protection scope of the utility model.

The ultrafiltration membrane described in the utility model is a known technology, and will not be repeated here.
