[0003] The water circulation device of the current washing machine often needs to be filtered through a filter, but since the relative movement between the filter and the liquid only depends on the flow of the liquid, the filtering performance is poor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a water circulation device for a washing machine.

[0006] By adopting the above technical solution, the waste liquid enters the filter pipe and moves towards the filter screen, thereby enhancing the relative movement between the filter screen and the waste liquid, thereby improving the filtering effect.

[0007] The utility model is further configured as follows: the rotating mechanism includes a transmission rod connected to the motor and a turntable connected to the transmission rod, a plurality of filter screens are fixedly connected to the side walls of the turntable, the filter pipe is provided with a through groove along its length direction on the side away from the ground, the through groove is connected to the through hole, the filtering working section of the filter pipe fits the shape of the peripheral wall of the turntable and is slidably connected to the turntable in the through groove.

[0026] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment, the water circulation device of the washing machine, such as Figure 1 As shown, the water circulation device of the water washing machine includes a filter pipe 11 and 6 filter screens 12. The inner wall of the filter pipe 11 and the outer edge of the filter screen 12 are slidably connected. The filter pipe 11 is provided with a through hole for the filter screen 12 to enter and exit the filter pipe 11 on the side away from the ground. The movement direction of the filter screen 12 is opposite to the flow direction of the waste liquid in the filter pipe 11. The outer wall of the filter pipe 11 is provided with a rotating mechanism for providing power to the filter screen 12. When the waste liquid enters the filter pipe 11 from the water washing working section of the water washing machine, the waste liquid contacts the filter screen 12 driven by the rotating mechanism, and a relative movement is generated between the two. The impurities contained therein are filtered by the filter screen 12, and then the rotating mechanism continues to drive the next filter screen 12 to continue to repeat the filtering process until the liquid flows out of the filtering working section of the filter pipe 11, so as to enhance the relative movement between the filter screen 12 and the waste liquid by the relative movement, thereby improving the filtering effect.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the rotating mechanism includes a transmission rod 18 connected to the motor and a rotating disk 13 connected to the transmission rod 18, a plurality of filter screens 12 are fixedly connected to the side wall of the rotating disk 13, a through groove 14 is opened along the length direction of the filter pipe 11 on the side away from the ground, and the through groove 14 is connected to the through hole, and the filtering working section of the filter pipe 11 fits the shape of the peripheral wall of the rotating disk 13 and is slidably connected to the through groove 14 with the rotating disk 13, so when the rotating disk 13 drives the filter screen 12, it prevents the waste liquid from leaking out of the through groove 14, and a plurality of metal rings 15 are fixedly connected to the side wall of the rotating disk 13, and the opening direction of the metal ring 15 is consistent with the rotation direction of the rotating disk 13. The outer diameter of 15 is equal to the inner diameter of the filter pipe 11, and the outer edge of the filter screen 12 is fixedly connected to the inner wall of the metal ring 15. The metal ring 15 provides support for the filter screen 12 to resist the impact of the water flow, ensuring that the positional relationship between the filtering direction of the filter screen 12 and the flow direction of the water flow remains unchanged. The filter screens 12 are arranged in an array around the turntable 13, and the angle between adjacent filter screens 12 is smaller than the angle of the filtering working section of the filter pipe 11. In this embodiment, the angle between adjacent filter screens 12 is 60 degrees. Because the filtering working section of the filter pipe 11 is 90 degrees, when the turntable 13 rotates, one or more filter screens 12 can always be kept working in the filter pipe 11.

[0029] like Figure 4 As shown, the filtering working section of the filtering pipe 11 is in an inferior arc shape. In this embodiment, the section is 90 degrees, and the inlet of the filtering working section of the filter screen 12 is perpendicular to the ground, and the outlet of the filtering working section of the filter screen 12 is parallel to the ground. When the flow entering the filtering pipe 11 is kept not excessive, the inferior arc shape can ensure that the pressure of the waste liquid is borne by the side of the filtering pipe 11 away from the through groove, and further ensure that the waste liquid will not overflow from the through groove 14. Each through hole is connected to a leak-proof pipe 16, and the arc of the leak-proof pipe 16 is 45 degrees and is concentric with the filtering working section of the filtering pipe 11. When the turntable 13 drives the filter screen 12 to enter or leave the filter pipe 11, part of the waste liquid will be brought out of the filter pipe 11 together. The leak-proof pipe 16 can prevent this part of the waste liquid from leaking out and recycle it into the filter pipe 11. The leak-proof pipe 16 is provided with a second through groove 17 along its length direction near the turntable 13. The second through groove 17 runs through the peripheral wall of the leak-proof pipe 16. The leak-proof pipe 16 fits the shape of the peripheral wall of the turntable 13 and is slidably connected to the turntable 13 in the second through groove 17, so as to ensure that the turntable 13 and the filter screen 12 can operate normally without affecting the function of the leak-proof pipe 16.

[0030] like Figure 5As shown, it also includes a fan 19 and an impurity collection box 20 which are arranged on the side of the rotating mechanism away from the pipeline. The blowing direction of the fan 19 is tangential to and in the same direction as the rotation direction of the rotating mechanism. The opening of the impurity collection box 20 faces the blowing port of the fan 19. The fan 19 and the impurity collection box 20 are fixedly connected by a bracket. The fan 19 adopts a high-pressure centrifugal fan to ensure the linearity of the blown wind. The wind blown by the fan 19 first reaches the side of the filter 12 away from the relatively moving waste liquid, so that the impurities can be blown out and enter the impurity collection box 20.

[0031] When the water circulation device of the water washing machine of the present embodiment is working, the waste liquid generated by the water washing machine enters the filter pipe 11, contacts the filter screen 12 in the working section of the filter pipe 11, and the filter screen 12 is driven by the turntable 13 to move relative to the waste liquid. At the same time, since a plurality of filter screens 12 are arranged on the turntable 13, the filter screen 12 in the working section of the filter pipe 11 can filter the waste liquid multiple times. After leaving the filter pipe 11, the impurities blocked by the filter screen 12 are blown off by the fan 19 to ensure its filtering effect. Therefore, the water circulation device of the water washing machine enhances the relative movement between the filter screen 12 and the waste liquid, thereby improving the filtering effect.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
