3. When the user chooses to use external force to drive the drum, the first clutch is in the disengaged state, the second clutch is in the engaged state, the external force acts on the pedal to make the front shaft rotate, the front shaft drives the rear shaft to rotate, and the rear shaft drives the second input shaft Rotation, the second input shaft drives the driven intermittent wheel intermittently, the driven intermittent wheel drives the electric reversing gear mechanism intermittently, the electric reversing gear mechanism drives the intermediate shaft to rotate intermittently, the intermediate shaft drives the output shaft to rotate intermittently, and the output shaft drives the drum intermittently Rotate, the electric reversing gear mechanism performs a reversing action as required, so that the steering of the intermediate shaft is changed, thereby realizing the steering of the output shaft, and finally the steering of the drum is changed.

4. When the user steps on the pedal at a constant speed, the intervals between the drums getting power are equal, so that the drums can realize the movement mode similar to that driven by the washing motor to ensure the washing effect and dehydration effect;

5. Due to the uniform intermittent transmission mechanism, the intermediate shaft does not need to be equipped with a braking device. When the electric reversing gear mechanism performs reversing action, the driven intermittent wheel is stationary, while the electric reversing gear mechanism, intermediate shaft and The transmission relationship of the output shaft is all gear transmission, so once the power is lost, it only takes a little time to automatically stop the rotation, so that during the reversing action, the intermediate shaft is also stationary, so that the reversing action can be carried out completely, ensuring the reversing action. The transmission relationship of each component backward is stable and reliable.

The drum washing machine for fitness as claimed in claim 8, characterized in that: the driving wheel includes an incomplete cylindrical gear and an active limit cam which are arranged coaxially and rotate synchronously; A cylindrical gear and a driven limit cam that are arranged on the shaft and rotate synchronously; the teeth of the incomplete cylindrical gear are arranged in segments and at least two sections are arranged in the circumferential direction, and the circumferential direction of the active limit cam is at least set A section of convex arc surface, the convex arc surface and the teeth of the incomplete cylindrical gear are arranged at intervals in the circumferential direction of the driving wheel; the cylindrical gear and the incomplete cylindrical gear are intermittently meshed, and the driven limit There is at least a section of concave arc surface on the circumference of the cam; when the cylindrical gear and the incomplete cylindrical gear are disengaged, the convex arc surface and the concave arc surface start to cooperate, and the convex arc surface is opposite to each other. The concave arc surface slides, and the driven intermittent wheel is in a static state; when the cylindrical gear and the incomplete cylindrical gear mesh with each other, the driven intermittent wheel is in a rotating state. 10. The drum washing machine for fitness as claimed in claim 9, characterized in that: said control seat is provided with a controller, said controller is electrically connected to said electric push rod through a reversing circuit, said The electric push rod is provided with a travel switch, and the travel switch is connected in series in the reversing circuit to control the steering of the electric push rod; The controller is electrically connected with the controller. The controller drives the electric push rod to act when the detector detects that the rotational speed of the driven intermittent wheel is zero. The handle is provided with a detection switch, and the detection switch is connected in series to the detector. between the controller.
