[0002] With the progress of science and technology, people's living standards are getting higher and higher, and daily household chores are gradually replaced by machines. As a common household appliance in daily life, washing machines have brought great convenience to people's life. Washing machines use mechanical energy generated by electricity to wash clothes. A washing machine generally includes a washing barrel and an upper cover. The upper part of the washing barrel is open, and the upper cover is arranged at the upper end of the washing barrel.

[0003] In order to prevent people from being injured by the high-speed rotating water-filled barrel when the washing machine is working, especially during dehydration, a micro switch triggered by the opening and closing action of the upper cover is often arranged at the rear of the upper cover. A protrusion is arranged at the rear of the upper cover to control the contact and non-contact of the micro switch contact. The specific working mode is as follows: when the upper cover is closed, the protrusion will top the contact of the micro switch, and the washing machine will work normally; when the upper cover is opened, the protrusion will rotate with the shaft and separate from the contact of the micro switch, the micro switch will generate a disconnection signal, and the power supply of the washing machine will be cut off, and the water-filled barrel of the washing machine will stop working immediately under the action of the brake.

[0004] During daily use, there is usually water accumulated on the upper cover of the washing machine. In the existing products, when the upper cover of the washing machine is opened, the water accumulated on the upper cover of the washing machine will flow to the protrusion from the hinge between the upper cover of the washing machine and the body of the washing machine under the action of gravity, and form water droplets on the protrusion. When the upper cover of the washing machine is closed and the protrusion contacts the micro switch, the water droplets on the protrusion will adhere to the micro switch, causing the micro switch to fail.

[0005] Therefore, it is a technical problem for those skilled in the art to design a washing machine upper cover that can prevent water accumulated on the top of the upper cover from flowing to the contact surface of the upper cover and the micro switch to prevent the micro switch from failing.

[0051] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0052] As Figures 1 to 12 ​As shown in the figure, an embodiment of the present invention introduces a washing machine cover 1, which includes a cover plate 3. A rotating shaft 4 is provided on one side of the bottom surface of the cover plate 3. The rotating shaft 4 is integrally formed with the cover plate 3. A protrusion 5 protrudes from the side of the rotating shaft 4 that is flush with the side of the cover plate 3 away from the washing machine cover plate 3. A trigger part 7 for triggering a micro switch 14 is connected to the side of the protrusion 5 away from the rotating shaft 4. The trigger part 7 rotates with the rotating shaft 4, thereby triggering the micro switch 14 through the opening and closing action of the washing machine cover 1.

[0053] Preferably, in this embodiment, a water-blocking part 6 is provided between the trigger part 7 and the end face of the protrusion 5 away from the rotating shaft 4. By setting the top of the water-blocking part 6 to extend beyond the top surface of the protrusion 5 and connecting the trigger part 7 to the bottom of the end face of the water-blocking part 6 away from the rotating shaft 4, water accumulated on the top of the washing machine cover 1 is prevented from flowing to the trigger part 7 as the washing machine cover 1 is opened and closed. At the same time, the top height of the water-blocking part 6 is set to be greater than the height of the trigger part 7, so that when the washing machine cover 1 is opened to the maximum position, the water accumulated on its top and the water droplets attached to the protrusion 5 cannot drip onto the trigger part 7 during the accumulation and dripping process on the top of the water-blocking part 6, thus ensuring the dryness of the trigger part 7 and ensuring the reliability of the operation of the trigger part 7.

[0054] Example 1

[0055] like Figures 8 to 12 As shown, in this embodiment, a rotating shaft 4 for installation is formed on one side of the bottom surface of the cover plate 3. A protrusion 5 protrudes from the side of the rotating shaft 4 that is flush with the cover plate 3 away from the cover plate 3. A water-blocking part 6 and a trigger part 7 are connected in sequence on the end face of the protrusion 5 away from the rotating shaft 4.

[0056] In this embodiment, the side of the top surface of the protrusion 5 away from the rotating shaft 4 protrudes from the top surface of the protrusion 5, forming a water-blocking rib 501. The water-blocking rib 501 extends along the length direction of the protrusion 5, thereby forming a groove shape with openings at both ends on the top surface of the protrusion 5. The water-blocking rib 501 constitutes the first protection against water accumulation. The protrusion 5 is also provided with a plurality of first drainage holes 10 penetrating the protrusion 5 from the top surface of the protrusion 5. The first drainage holes 10 are arranged along the length direction of the protrusion 5, so that the water blocked by the water-blocking rib 501 falls from the openings on both sides of the protrusion 5 and the first drainage holes 10.

[0057] Preferably, in this embodiment, the water-blocking part 6 includes a first water-blocking plate 601, which is disposed on the end face of the protrusion 5 away from the rotating shaft 4. The end face of the first water-blocking plate 601 near the rotating shaft 4 is integrally formed with the end face of the protrusion 5 away from the rotating shaft 4. The top of the first water-blocking plate 601 extends beyond the top surface of the protrusion 5, and the trigger part 7 is connected to the bottom of the end face of the first water-blocking plate 601 away from the rotating shaft 4. The top height of the trigger part 7 is lower than the top height of the first water-blocking plate 601. With the above arrangement, when the washing machine cover 1 is opened to the maximum state, the water droplets remaining on the protrusion 5 and the first water-blocking plate 601 accumulate and drip off the top of the first water-blocking plate 601, preventing water droplets from dripping onto the trigger part 7. At the same time, the width of the first water-blocking plate 601 is greater than the width of the trigger part 7, thereby preventing water accumulated on the top of the washing machine cover 1 from flowing to the trigger part 7 during the opening and closing of the washing machine cover 1, keeping the trigger part 7 dry at all times.

[0058] Preferably, in this embodiment, the bottom of the first baffle plate 601 extends beyond the bottom surface of the protrusion 5. A plurality of parallel ribs 13 extending from the bottom of the protrusion 5 to the bottom of the first baffle plate 601 are provided between the middle of the bottom surface of the protrusion 5 and the first baffle plate 601. The gaps between the ribs 13 correspond one-to-one with the first drain holes 10, thereby guiding the flow direction of the water discharged from the first drain holes 10. Simultaneously, by setting the bottom of the first baffle plate 601 to extend beyond the bottom surface of the protrusion 5, and connecting the trigger part 7 to the bottom of the end face of the first baffle plate 601 away from the rotating shaft 4, the height difference between the top of the first baffle plate 601 and the top of the trigger part 7 is increased, further preventing water droplets accumulated on the top of the first baffle plate 601 from dripping onto the trigger part 7, ensuring the reliability of the trigger part 7's operation.

[0059] Example 2

[0060] like Figures 8 to 12 As shown, in this embodiment, a rotating shaft 4 for installation is formed on one side of the bottom surface of the cover plate 3. A protrusion 5 protrudes from the side of the rotating shaft 4 that is flush with the cover plate 3 away from the cover plate 3. A water-blocking part 6 and a trigger part 7 are connected in sequence on the end face of the protrusion 5 away from the rotating shaft 4.

[0061] In the embodiment, the water blocking part 6 comprises a first water blocking plate 601 and a second water blocking plate 602, which are parallel to each other and connected in sequence between the end face of the protruding part 5 away from the rotating shaft 4 and the end face of the triggering part 7 close to the rotating shaft 4. The first water blocking plate 601 is arranged on the end face of the protruding part 5 away from the rotating shaft 4, and the end face of the first water blocking plate 601 close to the rotating shaft 4 is integrally formed with the end face of the protruding part 5 away from the rotating shaft 4. The top of the first water blocking plate 601 extends beyond the top surface of the protruding part 5, the second water blocking plate 602 is connected to the end face of the first water blocking plate 601 away from the rotating shaft 4, and the triggering part 7 is connected to the bottom of the end face of the second water blocking plate 602 away from the rotating shaft 4. The top of the first water blocking plate 601, the second water blocking plate 602 and the triggering part 7 gradually decreases in height. In this way, when the washing machine upper cover 1 is opened to the maximum extent, the water droplets remaining on the top of the washing machine upper cover 1 accumulated on the protruding part 5 fall to the top of the first water blocking plate 601, even if they fall during the opening process, they will only fall on the second water blocking plate 602 and not on the triggering part 7, thereby further enhancing the protection effect of the water blocking part 6.

[0062] Preferably, in the embodiment, a first connecting part 8 is arranged between the first water blocking plate 601 and the second water blocking plate 602, the first connecting part 8 protrudes from the end face of the first water blocking plate 601 and is connected to the end face of the second water blocking plate 602; a second connecting part 9 is arranged between the second water blocking plate 602 and the triggering part 7, the second connecting part 9 protrudes from the end face of the second water blocking plate 602 and is connected to the triggering part 7. Through the above arrangement, gaps exist between the first water blocking plate 601 and the second water blocking plate 602 and between the second water blocking plate 602 and the triggering part 7, so that when the washing machine upper cover 1 is closed, the water droplets accumulated on the top of the first water blocking plate 601 fall from the gap between the first water blocking plate 601 and the second water blocking plate 602 along the end face of the first water blocking plate 601 away from the rotating shaft 4, and the water droplets accumulated on the top of the second water blocking plate 602 fall from the gap between the second water blocking plate 602 and the triggering part 7 along the end face of the first water blocking plate 601 away from the rotating shaft 4, further preventing the water droplets from flowing to the triggering part 7.

[0063] Preferably, in the embodiment, a plurality of first drainage holes 10 are arranged on the protruding part 5, penetrating the protruding part 5 from the top surface of the protruding part 5; a second drainage hole 11 is arranged on the first connecting part 8, penetrating the first connecting part 8 from the top surface of the first connecting part 8; and a third drainage hole 12 is arranged on the second connecting part 9, penetrating the second connecting part 9 from the top surface of the second connecting part 9. Through the arrangement of the first drainage holes 10, the accumulated water on the side of the water blocking part 6 close to the rotating shaft 4 falls from the first drainage holes 10; through the arrangement of the second drainage hole 11 and the third drainage hole 12, when the washing machine upper cover 1 is closed, the water droplets accumulated on the top of the first water blocking plate 601 and the second water blocking plate 602 flow down along the end face of the first water blocking plate 601 and the second water blocking plate 602 and are discharged in time, preventing the water droplets from accumulating again.

[0064] Preferably, in this embodiment, the bottom of the first baffle plate 601 extends beyond the bottom surface of the protrusion 5, the first drain holes 10 are arranged along the length of the protrusion 5, and a plurality of ribs 13 are provided between the middle of the bottom surface of the protrusion 5 and the first baffle plate 601, extending from the bottom of the protrusion 5 to the bottom of the first baffle plate 601 and arranged in parallel. The gaps between the ribs 13 correspond one-to-one with the first drain holes 10, thereby guiding the flow direction of the water discharged from the first drain holes 10. The second baffle plate 602 is connected to the first baffle plate 601, and the bottom of the second baffle plate 602 continues to extend. The trigger part 7 is connected to the bottom of the end face of the second baffle plate 602 away from the rotating shaft 4, thereby further increasing the height difference between the trigger part 7 and the top of the first baffle plate 601, preventing water droplets accumulated on the tops of the first baffle plate 601 and the second baffle plate 602 from dripping onto the trigger part 7, enhancing the protective effect of the baffle plate 6, keeping the trigger part 7 dry at all times, and enhancing the reliability of the trigger part 7.

[0065] Preferably, in this embodiment, the cover plate 3 is integrally formed with the rotating shaft 4, the protrusion 5, the water-blocking part 6, and the trigger part 7.

[0066] Example 3

[0067] like Figures 1 to 12 As shown in the figure, an embodiment of the present invention introduces a washing machine, which includes a control panel 2 and a washing machine cover 1. The control panel 2 is provided with a through hole to form an annular structure. The rear end of the washing machine cover 1 is rotatably connected to the control panel 2, and the washing machine cover 1 is opened and closed by rotation.

[0068] To improve aesthetics and overall appearance, the top of the control panel 2 is recessed inward to form a recessed area, and a through hole is set in the recessed area. The washing machine cover 1 is housed in the recessed area, so that when the washing machine cover 1 is closed, the outer surface of the washing machine cover 1 is flush with the surface of the control panel 2, and the entire washing machine cover 1 and control panel 2 form a complete plane, thus improving aesthetics.

[0069] To reduce the force and user effort required when opening and closing the washing machine lid 1, the washing machine lid 1 in this embodiment is a foldable structure. Specifically, the cover plate 3 of the washing machine lid 1 includes a front side plate 301 and a rear side plate 302. The rear end of the front side plate 301 is hinged to the front end of the rear side plate 302, the rear end of the rear side plate 302 is rotatably connected to the control panel base 2, and the side of the front end of the front side plate 301 is slidably connected to the control panel base 2.

[0070] When the washing machine lid 1 needs to be opened, the front panel 301 is subjected to force, causing its front end to slide backward along the control tray base, and its rear end to tilt upward, thereby causing the rear panel 302 to rotate relative to the control tray base. This allows the front and rear panels 301 and 302 to fold open along their connection point, so that the user can place or remove clothes through the through-hole on the control tray base 2. In this embodiment, the washing machine lid 1 is divided into a front panel 301 and a rear panel 302 that are rotatably connected. The front panel 301 is slidably connected to the control tray base, and the rear panel 302 is rotatably connected to the control tray base 2 via a rotating shaft 4. When opening and closing the lid structure, the force on the rotating shaft 4 can be greatly reduced, thereby avoiding problems such as breakage or damage to the rotating shaft 4, thus improving the service life of the washing machine lid 1 structure and reducing the failure rate of the washing machine.

[0071] Preferably, in this embodiment, a micro switch 14 is also provided inside the control panel 2. The opening and closing action of the washing machine cover 1 can trigger the micro switch 14 to generate a closing and opening signal. The purpose is to ensure that when the user suddenly opens the washing machine cover 1 during the washing process, especially during the spin-drying process, the detection signal is quickly transmitted to the washing machine controller and the washing machine is controlled to stop rotating, thereby avoiding injury to the user from the high-speed rotating water tank.

[0072] Specifically, the bottom wall of the micro switch 14 is provided with contacts that at least partially protrude from the bottom wall of the micro switch 14 for triggering the micro switch 14. A trigger part 7 is connected to the rotating shaft 4 of the washing machine lid 1 and rotates synchronously with the rotating shaft 4. The trigger part 7 controls the contact and non-contact of the micro switch 14 contacts, thereby controlling the power-off when the washing machine is opened and the power-on when the lid is closed. The specific working method is as follows: when the washing machine lid 1 is closed, the trigger part 7 pushes against the contacts of the micro switch 14, and the washing machine works normally; when the lid is opened, the trigger part 7 rotates with the rotating shaft 4 and disengages from the contacts of the micro switch 14, the micro switch 14 generates an disconnect signal, cuts off the working power of the washing machine, and the water tank of the washing machine immediately stops working under the action of the brake.

[0073] Preferably, in this embodiment, a pivot 4 is formed on the rear side of the bottom surface of the rear side plate 302, and a protrusion 5 protrudes from the rear side plate 302. A water-blocking part 6 and a trigger part 7 are connected in sequence on the end face of the rear side of the protrusion 5.

[0074] like Figures 4 to 7 As shown, the protrusion 5, the water-blocking part 6, and the trigger part 7 all extend into the interior of the control panel 2 from the connection between the washing machine cover 1 and the control panel 2. The protrusion 5 is provided with a first drain hole 10 that penetrates the protrusion 5. When the washing machine cover 1 is closed, there is an installation gap between the rear pivot 4 of the rear side plate 302 and the control panel 2. The first drain hole 10 is located in the gap between the washing machine cover 1 and the control panel 2 and is used to drain the water accumulated on the top of the washing machine cover 1.

[0075] The water blocking part 6 comprises a first water blocking plate 601 and a second water blocking plate 602, which are parallel to each other and connected to the rear of the protruding part 5 in sequence. The first water blocking plate 601 is integrally formed with the rear end face of the protruding part 5. A water blocking rib 501 is arranged on the rear side of the top face of the protruding part 5, which protrudes from the top face of the protruding part 5 and extends along the length direction of the protruding part 5. The top of the first water blocking plate 601 extends beyond the top face of the protruding part 5. The second water blocking plate 602 is connected to the end face of the first water blocking plate 601 on the side away from the rotating shaft 4. The trigger part 7 is connected to the bottom of the end face of the second water blocking plate 602 on the side away from the rotating shaft 4. The top of the first water blocking plate 601, the second water blocking plate 602 and the trigger part 7 gradually decrease in height. When the washing machine top cover 1 is opened to the maximum extent, the water droplets accumulated on the top of the washing machine top cover 1 and remaining on the protruding part 5 will drip onto the top of the first water blocking plate 601. Even if the water droplets drip during the opening process, they will only drip onto the second water blocking plate 602 and will not drip onto the trigger part 7, thereby further enhancing the protection effect of the water blocking part 6. During use, if a large amount of water is poured on the top of the washing machine top cover 1 or a large amount of accumulated water on the top of the washing machine top cover 1 flows to the protruding part 5, the water blocking rib 501 and the first water blocking plate 601 cooperate with the control panel seat 2 to buffer the water flowing to the protruding part 5, prevent splashing and make the water flow down from the first drain hole 10 and the two sides of the protruding part 5.

[0076] Preferably, in the embodiment, a first connecting part 8 protrudes from the rear end face of the first water blocking plate 601. The second water blocking plate 602 is connected to the first water blocking plate 601 through the first connecting part 8. A second connecting part 9 protrudes from the rear side of the second water blocking plate 602. The second connecting part 9 connects the trigger part 7. The trigger part 7 is connected to the bottom of the rear end face of the second water blocking plate 602. The top of the first water blocking plate 601, the second water blocking plate 602 and the trigger part 7 gradually decrease in height. The second drain hole 11 is arranged on the first connecting part 8. The third drain hole 12 is arranged on the second connecting part 9.

[0077] The first connecting part 8 and the second connecting part 9 are arranged to form gaps between the first water blocking plate 601 and the second water blocking plate 602 and between the second water blocking plate 602 and the trigger part. When the washing machine top cover 1 is closed, the water droplets accumulated on the top of the first water blocking plate 601 will fall along the end face of the first water blocking plate 601 away from the rotating shaft 4 between the first water blocking plate 601 and the second water blocking plate 602. The water droplets accumulated on the top of the second water blocking plate 602 will fall along the end face of the first water blocking plate 601 away from the rotating shaft 4 between the second water blocking plate 602 and the trigger part, thereby further preventing the water droplets from flowing to the trigger part 7. The second drain hole 11 and the third drain hole 12 are arranged to make the water droplets accumulated on the top of the first water blocking plate 601 and the second water blocking plate 602 flow down along the end face of the first water blocking plate 601 and the second water blocking plate 602 and be discharged in time when the washing machine top cover 1 is closed, thereby preventing the water droplets from accumulating again.

[0078] Preferably, in the embodiment, the first water baffle 601 extends beyond the bottom surface of the protruding part 5, the first drain hole 10 is arranged along the length direction of the protruding part 5, and a plurality of rib plates 13 extending from the bottom surface of the protruding part 5 to the bottom of the first water baffle 601 and arranged in parallel are arranged between the middle part of the bottom surface of the protruding part 5 and the first water baffle 601, the gaps between the rib plates 13 correspond to the first drain hole 10 one by one, so that the rib plates 13 guide the flow direction of the accumulated water drained from the first drain hole 10.

[0079] The second water baffle 602 is connected to the first water baffle 601, the bottom of the second water baffle 602 continues to extend, and the trigger part 7 is connected to the bottom of the end surface of the second water baffle 602 away from the rotating shaft 4, so as to further increase the height difference between the trigger part 7 and the top of the first water baffle 601, prevent the water droplets accumulated on the top of the first water baffle 601 and the second water baffle 602 from falling on the trigger part 7, enhance the protection effect of the water baffle 6, keep the trigger part 7 dry at all times, and enhance the reliability of the trigger part 7.

[0080] In the embodiment, the first water baffle 601 and the second water baffle 602 are arranged to block and drain the accumulated water flowing to the protruding part 5, prevent the accumulated water from flowing to the trigger part 7, ensure the dryness of the trigger part 7, and thus ensure the accuracy of the action between the trigger part 7 and the micro switch 14, and increase the service life of the micro switch 14.

[0081] The above only describes the preferred embodiments of the present application, and does not limit the present application in any form. Although the present application has been disclosed as the above preferred embodiments, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the present application.
