Description

Technical Field

[0001] This utility model relates to the field of front control panel technology, specifically to a high wear-resistant plastic front control panel for washing machines. Background Technology

[0002] A washing machine is a machine used to wash clothes, towels, and other textiles. Based on their rated washing capacity, they are divided into household and commercial types. Most washing machines, in addition to basic washing functions, also have a spin-drying function, using high-speed rotation to generate centrifugal force to separate water from the clothes. Washing machines typically have a front control panel; however, existing front control panels have certain shortcomings. To prevent water or detergent from spilling onto the front control panel during use and causing it to malfunction, it is generally sealed to the bottom shell. This design greatly ensures the bottom shell's airtightness, thus guaranteeing the normal operation of the control panel. However, this design makes maintenance inconvenient, requiring the entire plastic bottom shell to be removed before the front control panel can be taken off, increasing maintenance time. Therefore, a new washing machine front control panel is proposed.

[0003] In the prior art, Chinese Patent No. CN220079467U discloses a front control panel for a washing machine, relating to the field of washing machine equipment technology. It includes a plastic base shell, a control panel inside the plastic base shell, a front control panel at the upper end of the plastic base shell, and a mounting assembly at the lower end of the front control panel for installation into the plastic base shell. While the prior art effectively seals the connection points to prevent water or detergent from entering the plastic base shell through the connection between the mounting base and the mounting plate during use, thus affecting the normal operation of the control panel, it uses multiple sets of locking screws to assemble and disassemble the front control panel. When assembling or disassembling the front control panel, workers must pull or push the sealing plate and then twist each set of locking screws one by one. This process is cumbersome and time-consuming, increasing the workload of workers and affecting work efficiency. Utility Model Content

[0020] like Figures 1 to 4As shown, a high wear-resistant plastic front control panel for a washing machine includes: a bottom shell 1; a control panel 2 installed in the center of the inner wall of the bottom shell 1; and fixing seats 3 installed on both sides of the inner wall of the bottom shell 1. The front control panel body 4 overlaps the fixing seats 3 and the top of the bottom shell 1. The outer walls of the front control panel body 4 and the bottom shell 1 are coated with a wear-resistant coating, which is a polyurethane coating. The front control panel body 4 is engaged with the fixing seats 3 through a locking assembly. The locking mechanism includes a pressing assembly, a twisting assembly, and a protective assembly. The pressing assembly locks the front control panel body 4, the twisting assembly unlocks the front control panel body 4, and the protective assembly protects the twisting assembly. In use, the device can lock the front control panel body 4 through the pressing assembly, unlock the front control panel body 4 through the twisting assembly, and protect the twisting assembly through the protective assembly. This allows workers to quickly disassemble and assemble the front control panel body 4, enabling timely maintenance of the front control panel body 4 or the control panel 2, without the need for workers to manually twist each set of screws, reducing workload and improving work efficiency.

[0021] In this embodiment, the pressing assembly includes an extension groove formed at one end of the top of the fixed base 3. An extension plate 5 slidably connected to the extension groove is installed at the bottom end of the front control plate body 4. A first rubber pad 6 is installed on one side of the inner wall of the extension groove. A reset groove is formed inside the fixed base 3 on one side of the extension groove. A reset plate 7 is slidably connected to the reset groove. A first spring 8 is installed between one end of the reset plate 7 and the inner wall of the reset groove. An abutment plate 9 is installed on one side of the outer wall of the extension plate 5. Corresponding inclined surfaces are formed at the opposite ends of the reset plate 7 and the abutment plate 9. A groove is formed on the side of the inclined surface of the outer wall of the reset plate 7. A second rubber pad 10 is installed on one side of the inner wall of the groove. First, the wear-resistant coatings applied to the outer walls of the front control panel body 4 and the bottom shell 1 are all polyurethane coatings, which have the characteristics of high wear resistance, impact resistance, and good flexibility. They are also resistant to water and chemical cleaning agents, which greatly improves the wear resistance of the front control panel body 4 and the bottom shell 1. When assembling the front control panel body 4, it can be placed inside the bottom shell 1 and overlapped with the top of the two sets of fixing seats 3, so that the extension plate 5 enters the inner side of the extension groove. The abutment plate 9 on the extension plate 5 first contacts the reset plate 7. The inclined surfaces of the two contacts, forcing the abutment plate 9 to squeeze the two sets of first springs 8 to retract.

[0022] In this embodiment, a locking groove is provided on the other side of the outer wall of the extension plate 5, and a toggle groove is provided on the other side of the inner wall of the extension groove. A movable rod 11 is rotatably connected to the inner side of the toggle groove. A toggle plate 12 is fixedly sleeved on one end of the outer wall of the movable rod 11. The toggle plate 12 is slidably connected to the locking groove. A torsion spring 13 is installed between the other end of the outer wall of the movable rod 11 and the inner wall of the toggle groove. Corresponding slopes are provided on the outer wall of the toggle plate 12 and the opposite ends of the extension plate 5. A sealing ring 14 is embedded and installed at the contact point between the inner wall of the bottom shell 1 and the outer wall of the front control plate body 4. Then, the slope on the extension plate 5 also contacts the slope on the toggle plate 12, causing the movable rod 11 and the torsion spring 13 to be compressed and retracted. Plate 5 continuously presses the first rubber pad 6 until the engaging groove on the extension plate 5 is close to and aligned with the actuating groove. Then, the actuating plate 12 is driven by the torsion spring 13 to pop out of the actuating groove, causing the actuating plate 12 to slide into the inner side of the engaging groove. As the extension plate 5 moves down, the abutment plate 9 also moves down. After the abutment plate 9 is aligned with the groove, the reset plate 7 is driven by the first spring 8 to pop out, causing the groove to cover the abutment plate 9. When the engaging groove is close to the actuating groove, the abutment plate 9 will also press the second rubber pad 10 to retract. After the actuating plate 12 is popped out, it can be loosened a distance so that one side of the actuating plate 12 abuts against the inner wall of the actuating groove to complete the abutment. In this way, the locking of the front control plate body 4 is completed.

[0023] In this embodiment, the protective component includes a protective plate 18 slidably connected to the inner side of the operating groove. The protective plate 18 is hinged to the outer wall of the bottom shell 1 via a hinge. A latching groove is provided on one side of the outer wall of the protective plate 18. A first magnetic block 19 is embedded in one end of the protective plate 18. A second magnetic block 20 that attracts the first magnetic block 19 is embedded in the inner wall of the operating groove. Furthermore, after locking, the protective plate 18 can be slid into the inner wall of the operating groove in conjunction with the hinge, so that the first magnetic block 19 and the second magnetic block 20 attract and connect, allowing the protective plate 18 to cover the torsion pull component to prevent the component from loosening due to accidental contact.

[0024] In this embodiment, the torsion assembly includes operating grooves on both sides of the outer wall of the bottom shell 1 and extending into the interior of the fixed base 3. A pull rod 15 is installed on one side of the reset plate 7 between the two sets of first springs 8. A pull groove extending into the inner side of the reset groove is provided on one side of the inner wall of the operating groove. The pull rod 15 and the pull groove are slidably connected. A first pull ring 16 is installed at one end of the pull rod 15 extending into the inner side of the operating groove. A second pull ring 17 is rotatably connected to one end of the movable rod 11 extending into the inner side of the operating groove. Furthermore, when it is necessary to disassemble the front control plate body 4 for component maintenance, the protective plate 18 can be opened, and then the front control plate body 4 can be continuously pressed downward to allow the abutment plate 9 to press the second rubber pad 1. 0 retraction, allowing the extension plate 5 to press the first rubber pad 6 back until the locking groove is aligned with the actuating groove again. Then, the second pull ring 17 can be fastened to rotate the movable rod 11, causing the actuating plate 12 to retract into the actuating groove. At this time, the front control plate body 4 can be released, and the first rubber pad 6 and the second rubber pad 10 can be driven to rise, preventing the actuating plate 12 from re-locking. Then, the first pull ring 16 can be fastened again to move the pull rod 15 inside the pull groove, causing the reset plate 7 to be dragged back to the inside of the positioning groove, away from the surface of the abutment plate 9. At this time, the first rubber pad 6 fully rebounds, completely lifting the front control plate body 4. The front control plate body 4 can then be removed for inspection and maintenance of damaged parts.

[0025] Implementation Plan: The wear-resistant coatings applied to the outer walls of the front control panel body 4 and the bottom shell 1 are both polyurethane coatings, which have the characteristics of high wear resistance, impact resistance, and good flexibility. They are also resistant to water and chemical cleaning agents, greatly improving the wear resistance of the front control panel body 4 and the bottom shell 1. When assembling the front control panel body 4, it can be placed inside the bottom shell 1 and overlapped with the tops of the two sets of fixing seats 3, so that the extension plate 5 enters the inner side of the extension groove. The abutment plate 9 on the extension plate 5 first contacts the reset plate 7. The inclined surfaces of the two contacts, forcing the abutment plate 9 to squeeze the two sets of first springs 8 to retract. At the same time, the slope on the extension plate 5 also contacts the toggle plate 12. The sloping contact causes the movable rod 11 and torsion spring 13 to retract under pressure. The extension plate 5 continuously presses against the first rubber pad 6 until the engaging groove on the extension plate 5 approaches and aligns with the actuating groove. Then, the actuating plate 12 is pushed out of the actuating groove by the torsion spring 13, causing the actuating plate 12 to slide into the inner side of the engaging groove. As the extension plate 5 moves down, the abutment plate 9 also moves down. After the abutment plate 9 aligns with the groove, the reset plate 7 is pushed out by the first spring 8, causing the groove to cover the abutment plate 9. When the engaging groove approaches the actuating groove, the abutment plate 9 also presses against the second rubber pad 10 to retract. After the actuating plate 12 is pushed out... This allows the toggle plate 12 to be loosened a short distance, causing one side of the toggle plate 12 to abut against the inner wall of the toggle groove, thus locking the front control panel body 4. After locking, the hinge can be used to slide the protective plate 18 into the inner wall of the operating groove, allowing the first magnet 19 and the second magnet 20 to attract and engage. The protective plate 18 covers the torsion pull assembly to prevent accidental contact that could cause the parts to loosen. When the front control panel body 4 needs to be disassembled for maintenance, the protective plate 18 can be opened, and then the front control panel body 4 can be pressed downwards continuously to cause the abutment plate 9 to press the second rubber pad 10 back, and the extension plate 5 to press the first rubber pad 6 back until... After aligning the locking slot with the actuating slot, engage the second pull ring 17 to rotate the movable rod 11, causing the actuating plate 12 to retract into the actuating slot. Then, release the front control plate body 4, allowing the first rubber pad 6 and the second rubber pad 10 to rise, preventing the actuating plate 12 from locking again. Next, engage the first pull ring 16 to move the pull rod 15 within the pull slot, causing the reset plate 7 to be pulled back into the repositioning slot, away from the surface of the abutment plate 9. At this point, the first rubber pad 6 fully rebounds, completely lifting the front control plate body 4. The front control plate body 4 can then be removed for inspection and maintenance of damaged components.
