Problems solved by technology

Although this structure further reduces the occupied space to a certain extent, because its principle is to use the inner circumferential space of the stator of the outer rotor motor to install the transmission device in the inner diameter space of the stator through the installation parts, it cannot be installed in the inner rotor without inner space. The application on the motor has certain limitations. At the same time, the motor body directly drives the shaft, and then decelerates the drive shaft through the transmission device installed in the inner diameter space of the motor, so it only reduces the occupied space to a certain extent, but the structure It is still not compact enough. Furthermore, when the volume of the transmission device needs to be increased in order to obtain a larger transmission ratio, the outer rotor motor must also increase the volume of the inner diameter to realize this invention. Obviously, this does not solve the substantive technical problem

Abstract

The invention discloses a gear speed reduction device. The gear speed reduction device comprises a rotating-shaft-free rotator for providing rotating kinetic energy, a speed reduction input component installed in the rotator, a speed reduction output component connected with the speed reduction input component, a first execution component and a second execution component, wherein the first execution component and the second execution component are connected with the speed reduction output component. The speed reduction input component is used for obtaining the rotating kinetic energy and rotating relative to the axis of the rotator by utilizing the obtained rotating kinetic energy; the speed reduction output component is used for outputting power with the rotating speed equal to or lower than the rotating speed of the rotator; and the first execution component and the second execution component are used for rotating under the power effect of the speed reduction output component. A speed reducer is installed in the rotator, and accordingly the volume of the whole gear speed reduction device is compressed. Besides, the gear speed reduction device is simple and compact in structure, saves energy and is small in noise. The invention further provides a washing machine with the gear speed reduction device and a washing method thereof.

Description

Technical field [0001] The present invention relates to the technical field of washing machines, in particular to a gear reduction device for washing machines, a washing machine with the gear reduction device and a washing method thereof. technical background [0002] The washing machine is a machine that removes the stains attached to the laundry through chemical decomposition and mechanical impact. It is mainly driven by a driving device to rotate the pulsator to agitate the water flow and the clothes to rotate to achieve the purpose of washing clothes. At present, the power source of the commonly used driving device is a motor. The output shaft of the motor transmits the torque when the motor rotates to the reduction gear, and then the output shaft of the reduction gear is connected with the pulsator to drive the pulsator to rotate. [0003] The speed of ordinary motors is relatively high. In order to obtain a suitable output speed, the motor needs to be decelerated in practical...
