The filter element 19 is fixed to the bottom end of the mounting plate 13. The top of the fixing tube 18 is sleeved with a mounting ring 12. The mounting ring 12 and the mounting plate 13 are detachably connected through a locking assembly. The filter element 19 is filled with activated carbon filter material. When working, the filter element 19 is initially The filtered sewage enters the fixed pipe 18 through the water pipe 10 and the connecting pipe 17 on one side, and flows upward from the fixed pipe 18 into the filter element 19, and is re-filtered through the activated carbon filter material in the filter element 19. The activated carbon adsorbs the residual chlorine that cannot be removed in the previous stage of filtration, and also adsorbs pollutants such as small molecular organic matter leaked from the previous stage. It has a more obvious adsorption and removal effect on odors, colloids, pigments, heavy metal ions, etc. in the water. The locking assembly is convenient for the staff to regularly disassemble the filter element 19 for replacement, thereby ensuring the filtering effect of the filter element 19.

The mounting member 21 is movably connected with a bolt 22, and the bolt 22 passes through the inner cavity of the mounting member 21. A spring 25 is fixed to the bottom of the inner cavity of the mounting member 21. The top of the spring 25 fits with a limiting member 24, and the limiting member 24 is sleeved with the bolt 22. The limiting member 24 is annular, and a thread groove is provided on the locking member 23. The bolt 22 is threadedly matched with the thread groove. When working, because the service life of the activated carbon filter material is It is not long, and the filter element 19 needs to be replaced regularly. When replacing the filter element 19, the staff only needs to rotate the bolt 22 outward to disengage the bolt 22 from the threaded groove to release the lock of the mounting plate 13 and the mounting ring 12. Because of the limiting effect of the limiting ring, the bolt 22 and the mounting plate 13 are an integrated structure and will not fall off, which is convenient for the staff to disassemble the bolt 22 and thereby increase the replacement rate of the filter element 19. When installing, the reverse operation can be performed. The elastic force of the spring 231 strengthens the locking and fixing effect of the bolt 22 on the mounting plate 13 and the mounting ring 12.

[0036] An annular groove is provided at the top of the fixed tube 18, and a sealing ring 20 is fixedly connected to the bottom end of the filter element 19, and the sealing ring 20 corresponds to the annular groove; when working, the sealing ring 20 at the bottom of the filter element 19 cooperates with the annular groove on the fixed tube 18, so that the sealing effect can be ensured when the filter element 19 and the fixed tube 18 are in contact, thereby preventing sewage from leaking from the gap between the filter element 19 and the fixed tube 18.

[0037] A heating device 5 is fixed on the outer wall of the laundry machine body 1, and a blower 6 is fixedly installed on the top of the heating device 5. The heating device 5 is connected to the inner cavity of the laundry machine body 1 through an air outlet pipe 7. When working, after dehydration is completed, the heating device 5 and the blower 6 start to work, the heating device 5 heats the air blown by the blower 6 and then introduces it into the air outlet pipe 7. Finally, the hot air enters the laundry machine body 1 from the air outlet pipe 7 to dry the dehydrated clothes.

[0038] A control member 28 is fixed to the inner cavity of the air outlet pipe 7, an electromagnet 29 is fixed on the inner wall of the control member 28, the electromagnet 29 is fitted with a permanent magnet 30, a spring 2 31 is fixedly connected to the side of the permanent magnet 30 away from the electromagnet 29, the other end of the spring 2 31 is fixedly connected to the inner wall of the control member 28, a support rod 32 is fixedly connected to the side of the permanent magnet 30 away from the spring 2 31, the other end of the support rod 32 penetrates the control member 28 and is fixedly connected to the valve core 27, the valve core 27 is fitted with the valve flap 26, and the valve flap 26 is fixed to the inner wall of the air outlet pipe 7; Working During drying, the electromagnet 29 in the control member 28 in the air outlet pipe 7 is energized, so that a magnetic repulsion force is generated between the electromagnet 29 and the permanent magnet 30, so that the permanent magnet 30 compresses the spring 231 and drives the valve core 27 at one end of the support rod 32 away from the valve flap 26, so that the hot air enters the washing machine body 1 through the air outlet pipe 7 to dry the dehydrated clothes. After drying, the electromagnet 29 is powered off, and the permanent magnet 30 returns to its original position under the elastic force of the spring 231. At the same time, the valve core 27 and the valve flap 26 are fitted to block the air outlet pipe 7 to prevent sewage from entering during washing.

[0039] Embodiment 2:

[0040] like Fig. 9 As shown, a clothing washing and drying processing device and an operating method thereof described in the present invention, the filter plate 16 in the filter tube 14 is a double-layer structure, and a filter cotton 33 is provided in the interlayer of the filter plate 16; when working, after the activated carbon filter material in the filter element 19 filters the sewage again, the sewage enters the filter tube 14, and the small molecular particle impurities in the sewage are further filtered through the filter cotton 33 in the interlayer of the filter plate 16, thereby improving the filtering effect and facilitating the staff to directly recycle the filtered sewage.

[0041] Working principle: the staff puts the dirty clothes into the washing machine body 1 and starts the switch on the control panel. The washing machine body 1 soaks and washes the dirty clothes. The sewage after washing is directly discharged from the sewage pipe 4. The clothes are then rinsed and dehydrated. The sewage generated by rinsing and dehydration enters the water treatment unit 2, and is first preliminarily filtered by the filter plate 16 and quartz sand filter material in the filter tube 1 9. The preliminarily filtered sewage enters the fixed pipe 18 through the water pipe 10 and the connecting pipe 17 on one side, and flows upward from the fixed pipe 18 into the filter element 19, and is re-filtered by the activated carbon filter material in the filter element 19. The activated carbon adsorbs the residual chlorine that cannot be removed in the previous stage of filtration, and also adsorbs the small molecular organic matter and other pollutants leaked from the previous stage, and has a more obvious adsorption and removal effect on the odor, colloids, pigments, heavy metal ions, etc. in the water. Finally, the filter tube 2 14 performs the final filtration and purification, and is discharged into the water storage tank 3 after completion, so that the staff can recycle it conveniently, thereby achieving the purpose of energy saving and green environmental protection. After the dehydration is completed, the heating device 5 and the blower 6 start to work. The device 5 heats the air blown by the blower 6 and then guides it into the air outlet pipe 7. At this time, the electromagnet 29 in the control part 28 in the air outlet pipe 7 is energized, so that a magnetic repulsion force is generated between the electromagnet 29 and the permanent magnet 30, so that the permanent magnet 30 compresses the spring 21 and drives the valve core 27 at one end of the support rod 32 away from the valve flap 26, so that the hot air enters the washing machine body 1 through the air outlet pipe 7 to dry the dehydrated clothes. After the drying is completed, the electromagnet 29 is powered off, and the permanent magnet 30 returns to its original position under the elastic force of the spring 21. At the same time, the valve core 27 The valve flap 26 fits together to seal the air outlet pipe 7 to prevent sewage from entering during washing. Because the service life of the activated carbon filter material is not long, the filter element 19 needs to be replaced regularly. When replacing the filter element 19, the staff only needs to rotate the bolt 22 outward to disengage the bolt 22 from the threaded groove to release the lock of the mounting plate 13 and the mounting ring 12. Because of the limiting effect of the limiting ring, the bolt 22 and the mounting plate 13 are an integrated structure and will not fall off, which makes it convenient for the staff to disassemble the bolt 22 and thereby increase the replacement rate of the filter element 19.

[0042] A method for using a clothes washing and drying device, which is applicable to the above-mentioned clothes washing and drying device, and the steps of the method are as follows:

[0043] S1: The staff puts the dirty clothes into the laundry machine and turns on the switch on the control panel. The laundry machine soaks and washes the dirty clothes. After washing, the sewage is directly discharged from the sewage pipe under the control of the single chip microcomputer.

[0044] S2: After washing, the clothes are rinsed and dehydrated. The wastewater generated by rinsing and dehydrating enters the water treatment unit under the control of the single-chip microcomputer, and finally enters the water storage tank from the water treatment unit.
