Abstract

The invention discloses a damping and sealing device of a foot-operated washing machine. The washing machine comprises a barrel body for containing water, an inner barrel which is arranged in the barrel body and is used for placing clothes, an impeller arranged in the inner barrel, an impeller shaft used for driving the impeller to rotate and a base arranged under the barrel body. A transmission device is arranged on the base, the impeller shaft can move up and down along the vertical direction to be matched with the transmission device to realize power output for washing and dewatering, a pivot shaft of the impeller shaft penetrates through the bottom of the barrel body and is provided with the damping and sealing device, the damping and sealing device comprises a sealing structure and a damping structure, the sealing structure adopts a skeleton oil seal, the lower side of the skeleton oil seal is sealed by grease, and the inner side of the skeleton oil seal is provided with a sealing lip; and the part of the pivot shaft of the impeller shaft penetrating through the bottom of the barrel body is provided with a boss, the bottom of the boss is provided with a round groove extending from bottom to top, the impeller shaft in the round groove is sleeved with an oil-containing bearing, a damping pad is sleeved outside the oil-containing bearing, and the lower side of the oil-containing bearing is provided with a sealing cover. The invention has the characteristics of good damping and sealing effects and simple structure.

Description

technical field [0001] The invention relates to a washing machine, in particular to a pedal-type sports washing machine, especially a shock-absorbing and sealing device for a pedal-type sports washing machine. 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 switched between...
