Problems solved by technology

Since the foot pedal is stepped on with one foot, the following problems inevitably occur during use: 1. When the foot pedal of the sports washing machine is stepped on with one foot, the force on the user's feet is uneven, which may easily cause user fatigue and reduce the load of the washing machine. Performance; 2. There is only one pedal and the pedals are generally designed off-axis. During the operation of the washing machine, it will inevitably cause asymmetrical force on the washing machine, which will affect the concentricity of the shaft and affect the vibration and vibration of the washing machine. Noise has a negative impact, etc.
[0009] The existing double-pedal scheme has a complex structure, and generally adopts multi-stage gear transmission, planetary gear transmission, and the output shaft and gear move up and down to realize the conversion of the washing and dehydration process, resulting in low reliability of the washing machine and restricting large-scale industrial production.

Embodiment 1

[0042] Such as figure 1 and figure 2 As shown, the second one-way bearing 84 and the third one-way bearing 85 described in this embodiment are arranged in the lower bevel tooth 82 in the upper and lower order, and the groove segments are two, respectively the upper groove segment 40 and the lower groove section 41 are arranged on the output shaft 4 in the order of up and down, and the distance between them satisfies: when washing, the output shaft 4 moves upward, only the first one-way bearing 83 is located in the upper groove section 40, and the upper bevel gear 81 Lost function, the second one-way bearing 84 and the third one-way bearing 85 act together on the output shaft 4, when the gear assembly drives the upper and lower bevel teeth 81, 82 to rotate forward and reverse, the upper bevel gear 81 rotates but does not act on the output shaft 4, And lower bevel gear 82 drives output shaft 4 forward and reverse to realize washing; The third one-way bearing 85 works together...

Embodiment 2

[0044] Such as image 3 and Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiment is that the upper and lower groove segments are combined into one groove segment 42, and the length of the groove segment 42 is between the first one-way bearing 83 and the third one-way bearing 85. The length of the distance between them satisfies: when washing, the output shaft 4 moves upward, only the first one-way bearing 83 is located in the groove section 42, the upper bevel gear 81 loses its function, the second one-way bearing 84 and the third one-way bearing 85 Working together on the output shaft 4, when the gear assembly drives the upper and lower bevel teeth 81, 82 to rotate forward and backward, the upper bevel gear 81 rotates but does not act on the output shaft 4, while the lower bevel gear 82 drives the output shaft 4 to rotate forward and reverse to achieve washing; dehydration , the output shaft 4 moves downward. At this time, only the se...

Embodiment 3

[0046] Such as Figure 5 and Figure 6 As shown, the difference between this embodiment and the above two embodiments is that the installation order of the second one-way bearing 84 and the third one-way bearing 85 is reversed, and the third one-way bearing 85 is above the second one-way bearing 84, and the A groove segment 43 is provided on the output shaft of the motor, and the length of the groove segment 43 satisfies: when washing, the output shaft 4 moves upwards, only the third one-way bearing 85 is located in the groove segment 43, and the first one-way bearing 83 and The second one-way bearing 84 works together on the output shaft 4. Since the first one-way bearing 83 and the second one-way bearing 84 act oppositely, when the gear assembly drives the upper and lower bevel teeth 81 and 82 to rotate forward and backward, the upper and lower bevel teeth Teeth 81, 82 drive the output shaft to reverse to realize washing; during dehydration, the output shaft 4 moves downwar...

Abstract

The invention discloses a double-pedal gear drive system used for a motile washing machine and the motile washing machine. The drive system comprises a base, an output shaft, two transmission mechanisms and a pedal plate, wherein the transmission mechanisms are used for transmitting motive power to the output shaft; the pedal plate provides the motive power; the output shaft moves up and down in the axle direction to realizing washing and dehydration clutch; the transmission system also comprises an upper umbrella tooth and a lower umbrella tooth which are axially sleeved on the output shaft at interval; the upper umbrella tooth and the lower umbrella tooth are axially fixed and do not move up and down along with the output shaft; the transmission mechanisms are symmetrically arranged relative to the upper umbrella tooth and the lower umbrella tooth; the upper umbrella tooth is internally provided with a first one-way bearing, the lower umbrella tooth is internally provided with a second one-way bearing and a third one-way bearing which are oppositely arranged, and the installation direction of the second one-way bearing is opposite to that of the third one-way bearing; the output shaft is provided with a groove section the diameter of which is smaller; and by means of the up and down movement of the output shaft, one of the one-way bearings fails so as to achieve washing positive and negative turn and dehydration coincidental turn. The double-footstep gear drive system provided by the invention has the characteristics of simple structure, uniform force and high reliability.

Description

technical field [0001] The invention relates to a washing machine, in particular to a sports washing machine and a transmission system, in particular to a double-pedal sports washing machine and a gear transmission system. Background technique [0002] Ordinary washing machines use electric energy to drive motors, such as fully automatic washing machines. The motor drives the pulsator or inner tub to perform washing or dehydration work, but the process of washing and dehydration is switched by a complex clutch device such as a deceleration clutch, and the process is complicated. , high cost; in addition, such as a double-tub washing machine, the pulsator and the centrifugal dehydration bucket are driven by two motors respectively to realize the functions of washing and drying, and the washing and dehydration process is also realized by electric power and two barrels; another The mop washing and drying device can be used for washing and drying in one set, but it cannot be swi...
