Description

Technical Field

[0001] This application relates to the field of household appliance accessories, and in particular to a water pump box for a washing machine's water suction component. Background Technology

[0002] The water pump box in a washing machine's water intake component is primarily used to drain water from the machine after washing. During the washing process, the water pump box collects wastewater and detergent residue from inside the washing machine and discharges it through the drain pipe after the wash is finished. It also has the function of collecting impurities in the washing machine, such as clothing fibers, hair, and paper scraps.

[0003] As shown in Chinese Patent Publication No. CN210368352U, the water pump box installation structure for washing machines still has the following shortcomings in actual use:

[0004] The aforementioned patent describes a water pump box installation structure for a washing machine. When the washing machine is in actual use, the water pump cover is locked by a locking tongue. When the washing machine is working, the water pump gradually collects and stores sewage in the water pump box. If the water pump box does not have a good seal, sewage can easily leak out. In addition, the washing machine itself will vibrate when it is working. When the locking tongue is subjected to frequent vibration, it is easy to pop out, which can cause the water pump cover to open accidentally, thus affecting the normal operation of the washing machine. Utility Model Content

[0005] To improve the problem of insufficient sealing of the water pump cover, this application provides a water pump box for the water suction component of a washing machine.

[0006] The technical solution provided in this application for a water pump box for a washing machine's water suction component adopts the following:

[0007] A water pump box for a water suction component of a washing machine includes a water pump box body, a connection port fixedly connected to the side wall of the water pump box body, and a sealing filter mechanism provided on the side wall of the water pump box body;

[0008] The sealing filter mechanism includes a water outlet pipe fixedly mounted on the side wall of the water pump housing. A connecting ring is slidably mounted on the outer wall of the water outlet pipe. A filter screen is movably mounted on the side wall of the connecting ring. An auxiliary ring is movably mounted on the side of the filter screen away from the connecting ring. A sealing cover is fixedly mounted on the inner wall of the auxiliary ring. A sealing ring is fixedly mounted on the inner wall of the sealing cover. A sealing ring is movably mounted on the inner wall of the sealing ring. A linkage disc is slidably mounted on the inner wall of the water outlet pipe. A guide tube is slidably mounted on the inner wall of the linkage disc. A snap-fit ​​component is mounted on the side wall of the linkage disc. A limit ring is fixedly mounted on the outer wall of the guide tube. An auxiliary disc is fixedly mounted on the outer wall of the guide tube.

[0009] The sealing filter mechanism is used to completely seal the outlet pipe and the sealing cover, thereby preventing accidental leakage of sewage.

[0010] By adopting the above technical solution, multiple snap-fit ​​components are symmetrically arranged at the center of the limiting ring, thereby making the connection more secure.

[0011] Preferably, the sealing filter mechanism further includes a connector fixedly connected to the side wall of the sealing cover, the end of the water outlet pipe near the water pump box is fixedly connected to the water pump box, the inner wall of the connecting ring is slidably connected to the outer wall of the water outlet pipe, the side of the connecting ring near the filter screen is engaged with the filter screen, the side of the filter screen away from the connecting ring is engaged with the auxiliary ring, the inner wall of the auxiliary ring is fixedly connected to the outer wall of the sealing cover, the side wall of the sealing cover is fixedly connected to the sealing ring, the inner wall of the sealing ring is engaged with the sealing ring, the end of the connector away from the sealing cover is fixedly connected to the linkage disc, and the side wall of the linkage disc is engaged with a limiting block fixedly connected to the inner wall of the water outlet pipe.

[0012] By adopting the above technical solution, the side wall of the filter screen is provided with multiple small water outlet holes, which can intercept impurities while ensuring the discharge of sewage.

[0013] Preferably, the inner wall of the linkage disc is slidably connected to the outer wall of the guide tube, and a connecting block is fixedly connected to the side of the linkage disc away from the connecting member.

[0014] By adopting the above technical solution, the guide pipe is funnel-shaped, so that the sewage will not come into contact with the internal structure of the sealed filter mechanism during the discharge process.

[0015] Preferably, the end of the connecting block away from the linkage disc is fixedly connected to the side wall of the snap-fit ​​component, and the inner wall of the limiting ring is fixedly connected to the outer wall of the guide tube.

[0016] By adopting the above technical solution, the size of the connecting block is smaller than the size of the through opening, which makes it easier to move the snap-fit ​​component.

[0017] Preferably, the side wall of the limiting ring has a through opening, the through opening is movably connected to the snap-fit ​​component, and the side of the limiting ring near the auxiliary disk is fixedly connected to the auxiliary disk.

[0018] By adopting the above technical solution, the outer diameter of the auxiliary disk is kept consistent with the outer diameter of the limiting ring, thus making the structural connection more reasonable.

[0019] Preferably, the inner wall of the auxiliary disc is fixedly connected to the guide tube, and a fixing cylinder is fixedly connected to the side of the limiting ring near the snap-fit ​​component.

[0020] By adopting the above technical solution, the diameter of the fixed cylinder cross-section is smaller than the outer wall area of ​​the limiting ring, thereby making the connection between the fixed cylinder and the limiting ring more stable.

[0021] Preferably, a telescopic cylinder is slidably connected to the inner wall of the fixed cylinder, and an abutment member that fits against the side wall of the linkage disc is fixedly connected to the end of the telescopic cylinder away from the fixed cylinder.

[0022] By adopting the above technical solution, the cross-sectional area of ​​the contacting component is smaller than the outer wall area of ​​the linkage disc, thus making the support more stable.

[0023] Preferably, the side of the abutment member away from the linkage disc is fixedly connected to a spring that is fixedly connected to the side wall of the limiting ring, and the spring moves through the telescopic cylinder and the fixed cylinder.

[0024] By adopting the above technical solution, the horizontal lengths of the telescopic cylinder and the fixed cylinder are kept consistent, thereby enabling the telescopic cylinder to have a longer sliding distance.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By pushing the sealing cover, the linkage disc slides horizontally, allowing the snap-fit ​​component to slide through the limiting ring and connect with the auxiliary disc. This causes the sealing ring to snap into the guide tube, and the sealing ring to fit against the guide tube. Then, by rotating the sealing cover, the snap-fit ​​component slides inside the auxiliary disc, causing the limiting ring to limit the snap-fit ​​component, thus sealing the guide tube and preventing sewage from flowing out of the drain pipe when the washing machine is working.

[0027] 2. By using the connecting ring to fit against the outer wall of the outlet pipe and the filter screen to engage with the connecting ring, the connecting ring protects the outlet pipe when sewage is discharged, and prevents small items in clothing pockets from being discharged into the sewer with the sewage and causing blockage. When it is necessary to remove it, simply release the engagement between the filter screen and the auxiliary ring. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0040] This application discloses a water pump box for a washing machine's water suction component.

[0041] Reference Figure 1 A water pump box for a washing machine's water suction component includes a water pump box body 1, a connection port 11 fixedly connected to the side wall of the water pump box body 1 for connecting to a sewage pipe, and a sealing filter mechanism 2 provided on the side wall of the water pump box body 1.

[0042] The staff connected the connection port 11 to the sewage collection pipe inside the washing machine, and then installed the water pump box 1 on the outside of the washing machine to facilitate sewage treatment.

[0043] Reference Figure 2 , Figure 3The sealing filter mechanism 2 includes an outlet pipe 21 fixedly mounted on the side wall of the water pump housing 1, a connecting ring 22 slidably mounted on the outer wall of the outlet pipe 21, a filter screen 23 movably mounted on the side wall of the connecting ring 22, an auxiliary ring 24 movably mounted on the side of the filter screen 23 away from the connecting ring 22, a sealing cover 25 fixedly mounted on the inner wall of the auxiliary ring 24, a sealing ring 26 fixedly mounted on the inner wall of the sealing cover 25, and a sealing ring 27 movably mounted on the inner wall of the sealing ring 26. The sealing ring 27 is made of rubber and can undergo elastic deformation. The sealing ring 26 and the guide pipe 211 are engaged to further improve the sealing performance. A linkage disc 29 is slidably mounted on the inner wall of the outlet pipe 21, and the guide pipe 211 is slidably mounted on the inner wall of the linkage disc 29. A snap-fit ​​component 213 is mounted on the side wall of the linkage disc 29, and a limiting ring 214 is fixedly mounted on the inner wall of the guide pipe 21. An auxiliary disc 216 is fixedly installed on the outer wall of the guide pipe 211. The sealing filter mechanism 2 is used to completely seal the outlet pipe 21 and the sealing cover 25 to prevent sewage from leaking out accidentally. The sealing filter mechanism 2 also includes a connector 28 fixedly connected to the side wall of the sealing cover 25. The end of the outlet pipe 21 near the water pump box 1 is fixedly connected to the side wall of the water pump box 1. The outlet pipe 21 is connected to the inside of the water pump box 1 to facilitate the discharge of sewage. The outer wall of the outlet pipe 21 is slidably connected to the inner wall of the connecting ring 22. The inner diameter of the connecting ring 22 is consistent with the outer diameter of the outlet pipe 21. A snap-fit ​​groove is opened on the side of the connecting ring 22 near the filter screen 23. The filter screen 23 snaps into the snap-fit ​​groove, thereby making the filter screen 23 snap into the connecting ring 22.

[0044] When it is necessary to seal the water outlet pipe 21, the staff pushes the sealing cover 25 to one side of the water outlet pipe 21. The sealing cover 25 will drive the auxiliary ring 24 to move synchronously, and the auxiliary ring 24 will drive the filter screen 23 to move synchronously.

[0045] Reference Figure 4 , Figure 5The auxiliary ring 24 has a second snap-fit ​​groove on the side near the filter screen 23, which snaps into the filter screen 23, thus securing the filter screen 23 to the auxiliary ring 24. The inner diameter of the auxiliary ring 24 matches the outer diameter of the sealing cover 25. The side of the auxiliary ring 24 away from the filter screen 23 is flush with the outer wall of the sealing cover 25, thus fixing the auxiliary ring 24 to the sealing cover 25. The side wall of the sealing cover 25 is fixedly connected to the side of the sealing ring 26 near the sealing cover 25, thus fixing the sealing ring 26 to the sealing cover 25. The inner wall of the sealing ring 26 has a third snap-fit ​​groove, which snaps into the sealing ring 27. Inside the snap-fit ​​groove three, the sealing ring 27 and the sealing ring 26 snap-fit ​​together. The end of the connector 28 away from the sealing cover 25 is fixedly connected to the side of the linkage disc 29 near the connector 28, so that the sealing cover 25 and the linkage disc 29 can move horizontally synchronously through the connector 28. The side wall of the linkage disc 29 is provided with a snap-fit ​​groove four, and the limiting block 210 snaps into the snap-fit ​​groove four, so that the limiting block 210 snaps into the linkage disc 29. The side of the limiting block 210 near the water outlet pipe 21 is fixedly connected to the inner wall of the water outlet pipe 21, so that the linkage disc 29 is limited by the limiting block 210.

[0046] The filter screen 23 will cause the connecting ring 22 to slide on the outer wall of the outlet pipe 21. The sealing cover 25 will also cause the linkage disc 29 to slide on the outer wall of the guide pipe 211 through the connector 28. The linkage disc 29 will also cause the connecting block 212 to move synchronously. The connecting block 212 will cause the snap-fit ​​213 to move synchronously.

[0047] Reference Figure 6 The inner diameter of the linkage disc 29 is consistent with the outer diameter of the guide tube 211, thus enabling a sliding connection between the linkage disc 29 and the guide tube 211. The connecting block 212 is fixedly connected to the side of the linkage disc 29 away from the connector 28, allowing the linkage disc 29 to drive the connecting block 212 to move synchronously. The side wall of the snap-fit ​​member 213 is fixedly connected to the end of the connecting block 212 away from the linkage disc 29, allowing the connecting block 212 to drive the snap-fit ​​member 213 to move synchronously. The inner diameter of the limiting ring 214 is consistent with the outer diameter of the guide tube 211, thus enabling a sliding connection between the limiting ring 214 and the guide tube 211. The tube 211 is fixedly connected, and the through-hole 215 is opened through the side wall of the limiting ring 214. The shape of the through-hole 215 is consistent with the size of the snap-fit ​​213, so that the snap-fit ​​213 can move through the through-hole 215. The auxiliary disc 216 is fixedly connected to the side of the limiting ring 214 near the auxiliary disc 216, so that the connection is tighter. The inner diameter of the auxiliary disc 216 is consistent with the outer diameter of the guide tube 211, so that the auxiliary disc 216 and the guide tube 211 are fixedly connected. The side wall of the auxiliary disc 216 is provided with a rotating groove, and the snap-fit ​​213 is slidably connected with the rotating groove.

[0048] The linkage disc 29 will push the contact member 219 to move synchronously. The contact member 219 will drive the telescopic cylinder 218 to slide on the inner wall of the fixed cylinder 217. The spring 220 will be compressed. When the snap-fit ​​member 213 slides through the through-hole 215 and connects with the auxiliary disc 216, the sealing ring 26 will also snap with the side of the guide tube 211 near the sealing cover 25. The sealing ring 27 will squeeze the guide tube 211.

[0049] Reference Figure 7 The fixed cylinder 217 is fixedly connected to the side of the limiting ring 214 near the snap-fit ​​part 213. The inner diameter of the fixed cylinder 217 is consistent with the outer diameter of the telescopic cylinder 218, so that the fixed cylinder 217 and the telescopic cylinder 218 are slidably connected. The end of the telescopic cylinder 218 away from the fixed cylinder 217 is fixedly connected to the end of the abutment 219 near the telescopic cylinder 218. The side of the abutment 219 near the linkage disc 29 is in contact with the side wall of the linkage disc 29. The side of the abutment 219 away from the linkage disc 29 is fixedly connected to the end of the spring 220 near the abutment 219. The end of the spring 220 near the limiting ring 214 is fixedly connected to the side wall of the limiting ring 214. The cross-sectional diameter of the spring 220 is smaller than the inner diameter of the telescopic cylinder 218 and the abutment 219, so that the spring 220 can move through the telescopic cylinder 218 and the fixed cylinder 217.

[0050] The operator then rotates the sealing cover 25, which in turn drives the linkage disc 29 to rotate via the connector 28. The linkage disc 29, in turn, drives the snap-fit ​​213 to rotate within the auxiliary disc 216 via the connecting block 212. This causes the through-hole 215 to limit the snap-fit ​​213 and seal the outlet pipe 21. When drainage is required, the operator simply rotates the sealing cover 25 in the opposite direction, which releases the snap-fit ​​213 from the through-hole 215. At this time, the spring 220 pushes the linkage disc 29 to reset via the contact member 219, allowing the sewage to flow out from the guide pipe 211 and the filter screen 23.

[0051] Among them, the water pump box 1 and the connection port 11 are existing technologies, and their structural principles will not be described in detail. They also include the washing machine body, water pump, sewage pipe, pipe connector, etc., which are not the main technologies and will not be described in detail.

[0052] The implementation principle of a water pump box for a washing machine's water suction component in this application embodiment is as follows:

[0053] When it is necessary to seal the outlet pipe 21, the operator pushes the sealing cap 25 to one side of the outlet pipe 21. The sealing cap 25 will cause the filter screen 23 to move synchronously. The filter screen 23 will cause the connecting ring 22 to slide on the outer wall of the outlet pipe 21. The sealing cap 25 will also cause the linkage disc 29 to slide on the outer wall of the guide pipe 211 through the connector 28. The linkage disc 29 will also cause the snap-fit ​​part 213 to move synchronously. The linkage disc 29 will push the abutment part 219 to move synchronously. The abutment part 219 will drive the telescopic cylinder 218. As the spring 220 slides along the inner wall of the fixed cylinder 217, it will be compressed. When the snap-fit ​​213 slides through the through-hole 215 and connects with the auxiliary disc 216, the sealing ring 26 will also snap with the side of the guide tube 211 near the sealing cover 25. The sealing ring 27 will press against the guide tube 211. Then, the operator rotates the sealing cover 25, thereby driving the snap-fit ​​213 to rotate within the auxiliary disc 216 through the connecting block 212 via the connecting piece 28, thus limiting the snap-fit ​​213 at the through-hole 215.

[0054] When drainage is required, the staff only needs to rotate the sealing cover 25 in the opposite direction to release the locking member 213 from the through opening 215. The spring 220 will push the linkage disc 29 through the contact member 219 to complete the reset, so that the sewage can flow out from the filter screen 23.

[0055] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
