Water purification system used for washing machine

Abstract

The invention discloses a water purification system used for a washing machine. The water purification system comprises a dewatering pump module, a water purification device and a T-junction, wherein the dewatering pump module, the water purification device and the T-junction are connected; the dewatering pump module and the water purification device are connected with the T-junction through a shared shunting water discharging module; the effluent of the dewatering pump module and / or the water purification device is externally discharged out of the washing machine through the same T-junction; the shunting water discharging module can be used for communicating the dewatering pump module and the water purification device to enable the effluent of the dewatering pump module to flow into the water purification device to be subjected to purification processing. According to the water purification system provided by the invention, a self-cleaning water circuit structure is realized, and a system filtering effect is achieved. According to the shunting water discharging valve module, switching between a water returning water route and a water discharging water route can be artfully realized. The water purification system has the advantages of simple structure and easiness in overhauling and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a water purification system for washing machines. Background technique [0002] The drain pump of the drum washing machine is generally equipped with a filter to remove the dander generated during the washing process and prevent it from entering the sewer pipe and blocking the sewer. While doing laundry, the drain filter also blocks the debris and dirt generated during washing, and since the device is located at the bottom of the entire washing machine, after the clothes are washed, if the dirt on the filter is not removed regularly , then in long-term normal use, the dirt will re-enter the drum under the drive of the water flow to contaminate the clothes that need to be washed. [0003] After investigation, it was found that the drainage filter of the drum washing machine has a simple structure and poor filtering effect, and debris such as lint can easily enter the imp...

AI Technical Summary

Problems solved by technology

[0003] After investigation, it was found that the drainage filter of the drum washing machine has a simple structure and poor filtering effect, and debris such as lint can easily enter the impeller of the drainage pump and cause the impeller to stall, or cause the sealing ring of the drainage valve to leak due to foreign matter that cannot return to its original position; The model with water cleaning function only has the filter structure of the filter device itself, without other filter protection devices

[0004] At present, the drainage module of the washing machine for water purification on the market has only a little filtering effect on the water purification filter device. The water purification filter module does not have a self-flushing function, and it needs to be disassembled and cleaned or directly replaced. The switching is complicated, resulting in a complex internal structure of the washing machine, which is difficult to repair and maintain

[0005] At present, there is no overall water filtration solution and technology for washing drum washing machines. It is only the filtration protection of the separate components. At the same time, the return water channel and the drainage water channel cannot be switched reasonably and effectively, but are realized through a relatively complicated structure. ; The filter protection device or structure of each component does not play a role in filter protection for other components in the system, or only plays a small protective role, and the filter protection device or structure design of the component itself is relatively unreasonable, which may easily cause its own The damage of the system is not considered and designed from the system, which makes the system have a high failure rate and is not easy to troubleshoot
