Reclaimed water processing device of washing machine, water processing method and washing machine

Abstract

The invention relates to a reclaimed water processing device of a washing machine, a reclaimed water processing method and the washing machine. The washing machine comprises an outer barrel, an inner barrel and a drive device. A water inlet and a water outlet are formed in the outer cylinder. A water inlet pipe is connected with the water inlet. A draining pipe is connected with the water outlet. The washing machine further comprises a water filter pipe, a filter unit and a water return pipe. The water filter pipe is connected with the draining pipe through a first three-way valve. The water return pipe is connected with the water inlet pipe through a second three-way valve. An inlet of the filter unit is connected with the water filter pipe, an outlet thereof is connected with the water return pipe. At least one water pump is disposed on a water circulation loop formed by the draining pipe, the water filter pipe, the filter element, the water return pipe and the water inlet pipe. Reclaimed water generated during operation of the washing machine flows into the filter unit through the water filter pipe, is filtered by the filter unit, and flows back to the inner barrel of the washing machine to take part in subsequent working procedures, and accordingly water user amount in the whole washing process is reduced, and water recycling is achieved.

Description

technical field [0001] The invention relates to a reclaimed water treatment device and method, in particular to a reclaimed water treatment device, a treatment method and a washing machine which are used on a washing machine and can realize water recycling, and belong to the technical field of washing machines. Background technique [0002] The traditional washing machine washes the clothes with water. After washing, all the washing water is discharged, and then re-injected with clean water for rinsing of the clothes. After each rinse, the rinsing water is also drained and then injected with clean water. The entire washing process consumes a lot of water , a serious waste. [0003] In order to achieve the purpose of saving water, in the prior art, a reclaimed water treatment device is used to filter the washing water of the washing machine for recycling. The reclaimed water treatment devices in the prior art generally adopt ceramic membrane filtration, and need to separatel...

Problems solved by technology

The reclaimed water treatment devices in the prior art generally adopt ceramic membrane filtration, and need to separately set up structures such as water storage tanks. Ceramic membranes are made of specially processed non-polar ceramic materials. There are The production process is complicated, the cost is high, and the filtration cycle is long. In addition, in the process of filtering water, the ceramic membrane is polluted and the cleaning effect is poor. Due to the filtration flux of the membrane, the application range is limited, and there are also short service life. question
