Description

Technical Field

[0001] The utility model belongs to the technical field of washing machine accessories, in particular to a washing machine drainage tractor driven by a worm helical gear. Background Art

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. The drainage tractor is an important component for the normal operation of the washing machine, and mainly controls the drainage of the washing machine. The drainage tractor has a power-off recovery function, that is, after a power outage, the motor in the tractor stops working, and the washing machine drain valve (spring) pulls out the traction rope to reset it, so that the traction rope returns to the initial state and waits for the next traction action.

[0003] At present, the gear mechanism used in the drainage traction device for washing machines in the prior art is mostly a spur gear pair plus a planetary gear system. The transmission ratio of each single-stage transmission is relatively small, the transmission accuracy is not high, and the overall transmission structure is complex, resulting in the existing drainage traction device for washing machines being not compact in structure, causing energy waste, resulting in low mechanical efficiency, and more shafts required for the traction system, which will further reduce the transmission efficiency. At the same time, since the existing drainage traction device uses a spur gear mechanism, multiple stages of transmission are required to make up a sufficient transmission ratio to meet the load-bearing requirements. This type of washing machine drainage traction system requires more shafts and parts, and has a higher manufacturing cost.

[0004] Therefore, we design a washing machine drainage tractor with worm helical gear transmission to solve the above problems. Utility Model Content

And the magnetic ring driving spring 28 is sleeved outside the fifth shaft body 5.

[0050] The sixth shaft body 6 is arranged on one side of the fifth shaft body 5. A transition gear 12 is arranged on the sixth shaft body 6. The upper part of the transition gear 12 is meshed with the upper part of the aluminum ring gear 19. The seventh shaft body 7 is arranged on one side of the sixth shaft body 6.

[0053] Embodiment:

[0054] During use, the motor driving part 16 in the present utility model is connected to the driving groove on the reverse stop ratchet 15 driven by the motor. The motor rotates clockwise. Under the action of the second shaft body 2, the return system driving helical gear 18 is driven to rotate. Under the meshing action of the return system driving helical gear 18 and the magnetic ring driving helical gear 27, the purpose of driving the magnetic ring driving helical gear 27 is achieved, and thus the adjusting magnetic ring 20 is driven by the magnetic ring driving spring 28;

[0055] Among them, the return system driving helical gear 18 rotates right-handed, driving the magnetic ring driving helical gear 27 to rotate counterclockwise, driving the aluminum ring gear 19 to rotate synchronously counterclockwise. Under the meshing action between the upper part of the intermediate gear 12 and the upper part of the aluminum ring gear 19, the intermediate gear 12 is driven to rotate clockwise. Combining with the meshing action between the sector gear 13 and the lower part of the intermediate gear 12, the sector gear 13 is driven to rotate counterclockwise. Through the counterclockwise rotation of the sector gear 13, the reverse stop boss 14 is driven away from the reverse stop ratchet 15. The sector gear 13 rotates towards the direction of the eighth shaft body 30 until it contacts the stop gear 23, causing the stop gear 23 to stop rotating. Under the meshing action between the stop gear 23 and the stop gear ring 2202, the gear ring frame 22 is further limited and locked, making the gear ring frame 22 unable to rotate. When the motor rotates counterclockwise, the reverse stop ratchet 15 and the reverse stop boss 14 abut against each other and cannot rotate;

[0056] When the motor rotates clockwise, the worm 17 and the return system drive bevel gear 18 are driven by the second shaft body 2 to work. Under the meshing action of the worm 17 and the clutch bevel gear 8, the clutch bevel gear 8 is driven by the worm 17 to rotate clockwise. Under the mutual cooperation of the clutch convex teeth 801 and the clutch ratchet 2101, the purpose of driving the sun gear 21 by the clutch bevel gear 8 is realized. The ring gear frame 22 cannot rotate under the action of the stop gear 23. The planet carrier 9 is used as a wire rope traction member. The hook control assembly 901 on the planet carrier 9 drives the hook control lever 11, so that the adjusting hook 10 rotates counterclockwise. Under the elastic action of the clutch spring 25, the clutch bevel gear 8 is separated from the sun gear 21, and the traction ends.

[0057] At this time, the motor continues to work. The sun gear 21 has a tendency to rotate counterclockwise under the action of the heavy object. The hook on the adjusting hook 10 hooks the stop convex teeth 2102 to prevent this tendency and achieve a holding effect.

[0058] When the motor stops working, the sector gear 13 is separated from the stop gear 23 under the action of the return spring 29. The ring gear frame 22 is no longer fixed, and the wire rope can return to its original position under the action of the heavy object for the next traction.

[0059] In the present utility model, through the combined action of the worm 17 and the return system drive bevel gear 18, combined with the clutch assembly, the original gear transmission mechanism is replaced, making the overall structure of the drainage tractor for washing machines simpler and more compact. At the same time, the transmission mechanism composed of the worm 17 and the return system drive bevel gear 18 has a greater bearing capacity, stronger impact resistance, and more stable transmission. There are only two-stage transmissions, making the transmission efficiency higher. Without changing the original motor power, a greater force can be output to drive a greater mass. Therefore, when pulling the same mass, a motor with a smaller power can be used.

[0060] At the same time, the combined cooperation of the sector gear 13, the reverse stop convex platform 14, the reverse stop ratchet 15, and the return spring 29 forms a stop assembly, which is combined with the clutch assembly to enable the drainage tractor for washing machines to effectively achieve stopping after the traction is in place, ensuring the stability of the tractor during use, and enabling the holding function when the motor continues to work.

[0061] It should be further noted that the installation structure, connection method, or setting method of each component in the present utility model are all common mechanical methods, and any implementation that can achieve its beneficial effects can be carried out.
