Description

Technical Field

[0001] The utility model relates to the technical field of adjustable door magnets for washing machines, in particular to an adjustable door magnet for washing machines. Background Art

[0002] The use of adjustable door magnets in washing machines is mainly for safety and functionality considerations. The door magnets mainly play the role of switch control. When the door of the washing machine is closed, the door magnets will trigger a signal to inform the washing machine that it can start working. If the door is not closed or opened, the door magnets will prevent the washing machine from running to ensure safe use. The design of adjustable door magnets allows users to adjust the sensitivity and position of the door magnets according to the specific situation of the washing machine to ensure the best working effect. At the same time, this design also improves the durability and reliability of the washing machine and reduces the operation problems of the washing machine caused by door magnet failure.

[0003] According to Chinese patent CN201921530897.3, in this application, a magnetic switch and an adjustment mechanism are provided, and the screw knob on the adjustment port is turned to rotate the screw knob, and the screw knob spirally pushes the adjustment seat, and the adjustment seat slides horizontally on the sliding port along the slider at the bottom of the adjustment seat, and the adjustment seat adjusts the position of the magnetic switch at its top. The adjustment seat is arranged on one side of the bottom end of the magnetic switch, which is convenient for controlling the position adjustment of the magnetic switch, so that the magnet and the magnetic switch are aligned with each other to ensure the induction effect, the structure is simple, and the adjustment is easy. The sealing ring provided on the connection port and the interference fit with the matching seat are conducive to sealing and protecting the protective cover and the double wires in the protective cover, thereby enhancing the tightness of the overall interface.

[0004] Although the magnetic switch and adjustment mechanism in the application can effectively deal with the problem that the adjustable door magnet has poor adjustment effect after installation and is difficult to quickly adjust the installation deviation, during use, the adjustable door magnet may cause component wear or loosening due to long-term use or frequent adjustment, thereby affecting the normal operation of the door magnet. For this reason, we propose an adjustable door magnet for a washing machine. Utility Model Content

By pressing the magnet switch 7 and turning on the power, the first magnet 4 and the second magnet 5 are tightly attracted together, and the magnetic properties of the first magnet 4 and the second magnet 5 are opposite.

[0030] Furthermore, the lubrication structure includes a third magnet 9, a lubricating oil reservoir 11 and a first spring 12. The first magnet 4 is provided with a lubricating oil reservoir 11, one end of the lubricating oil reservoir 11 passes through one end of the first magnet 4, the inner wall of the lubricating oil reservoir 11 is fixedly connected to the first spring 12, one end of the first spring 12 is fixedly connected to the third magnet 9, the outer side of the third magnet 9 is movably connected to the inner wall of the lubricating oil reservoir 11, the third magnet 9 and the first magnet 4 have the same magnetic properties, the third magnet 9 connected to the inner wall of the lubricating oil reservoir 11 is also attracted by the second magnet 5, and moves in the direction of the second magnet 5, and the first spring 12 at one end of the third magnet 9 The spring 12 limits the third magnet 9 to ensure that the third magnet 9 will not completely separate from the lubricating oil reservoir 11. When the third magnet 9 is in contact with one end of the second magnet 5, one end of the third magnet 9 is movably connected to one end of the lubricating oil reservoir 11, and the lubricating oil in the lubricating oil reservoir 11 moves with the movement of the third magnet 9. When the end of the third magnet 9 connected to the first spring 12 is snapped together with one end of the lubricating oil reservoir 11, a small gap will exist, and the lubricating oil will be squeezed out of the gap. When the first magnet 4 leaves the second magnet 5, the third magnet 9 returns to the lubricating oil reservoir 11 under the action of the first spring 12.

[0031] Furthermore, the replenishing structure includes a replenishing groove 13 and a replenishing cover 14. The replenishing groove 13 is opened on one side of the lubricating oil reservoir 11, and one end of the replenishing groove 13 passes through the lubricating oil reservoir 11, and the replenishing cover 14 is clamped on the inner wall of the other end of the replenishing groove 13.

[0034] Furthermore, a placement groove 15 is provided on the door cover 2 of the washing machine, and the inner wall of the placement groove 15 is movably connected with the second magnet 5 . The placement groove 15 provided on the door cover 2 of the washing machine is used to place the second magnet 5 .

[0035] Furthermore, a second spring 16 is fixedly connected to the inner wall of the placement slot 15 , and the top of the second spring 16 is fixedly connected to one end of the second magnet 5 . The second spring 16 on the placement slot 15 serves to connect the placement slot 15 .

[0036] Working principle:

[0037] When in use, by pressing the magnet switch 7 and turning on the power supply, the first magnet 4 and the second magnet 5 are tightly attracted together, and the magnetic properties of the first magnet 4 and the second magnet 5 are opposite. At the same time, the third magnet 9 connected to the inner wall of the lubricating oil reservoir 11 is also attracted by the second magnet 5 and moves in the direction of the second magnet 5. The first spring 12 at one end of the third magnet 9 limits the third magnet 9 to ensure that the third magnet 9 will not completely separate from the lubricating oil reservoir 11. When the third magnet 9 fits with one end of the second magnet 5, one end of the third magnet 9 just touches the lubricating oil reservoir 11. One end of the reservoir 11 is movably connected together, and the lubricating oil in the lubricating oil reservoir 11 moves with the movement of the third magnet 9. When the end of the third magnet 9 connected to the first spring 12 is snapped together with one end of the lubricating oil reservoir 11, a small gap will exist, and the lubricating oil will be squeezed out from the gap and flow into the auxiliary groove 8, and then flow along the lubrication pipeline 10 to lubricate the parts along the way. When the first magnet 4 leaves the second magnet 5, the third magnet 9 returns to the lubricating oil reservoir 11 under the action of the first spring 12. When the lubricating oil reservoir 1 1 is empty, the supply cover 14 is opened, and the lubricating oil is introduced into the lubricating oil storage 11 along the supply groove 13. The placement groove 15 provided on the washing machine door cover 2 is used to place the second magnet 5. The second spring 16 on the placement groove 15 serves to connect the placement groove 15. The second magnet 5 is designed the same as that on the first magnet 4. One end of the third magnet 9 is fixedly connected to the first spring 12, and the other end is movably connected to the second spring 16. The difference is that the magnetism of the third magnet 9 on the second magnet 5 is the same as that of the first magnet 4. When the first magnet 4 contacts the second magnet 5, the third magnet 9 on the second magnet 5 will move toward the second spring 16, and one end of the third magnet 9 is movably connected to one end of the lubricating oil reservoir 11. The lubricating oil in the lubricating oil reservoir 11 will move with the movement of the third magnet 9. When the end of the third magnet 9 connected to the first spring 12 is snapped together with one end of the lubricating oil reservoir 11, a small gap will exist, and the lubricating oil will be squeezed out of the gap and flow into the auxiliary groove 8, and then flow along the lubrication pipeline 10 to lubricate the parts along the way.
