Impeller transmission device for suspension upright type washing machine

Abstract

The invention relates to a driving device for washing machine, comprising inner drum, weave wheel set on the bottom of inner drum, motor and clutch, characterized in that motor is set on one side of the bottom of outer drum; a belt speed reduction which is that small belt wheel fixed on the output shaft of motor drives the big belt wheel on the input inner and outer shaft; a reduction gearbox which is provided with a driving gear connected with input inner shaft and a pair of follower gears mounted with driving gear and rotating in mutual reversal, and bevel gear mounted with bevel wheel ring on the back side of weave wheel is set on the output ends of two following gears. By motor-belt wheel-clutch-driving device for inner and outer driving shaft and inverter technology inner drum rotates from low speed to high speed gradually. It helps to exert motor efficiency and decrease production cost. Service life and performance are improved by sealed reduction gearbox.

Description

technical field [0001] The invention relates to a transmission device of a washing machine, in particular to a pulsator transmission device of a suspension washing machine. Background technique [0002] The function of existing full-automatic pulsator washing machine transmission device is two, and the one, the rotational energy of motor is delivered to washing tub; The 2nd, the rotational energy of motor is delivered to pulsator. Generally, the rotating speed of the pulsator is about 120-160r / min, the rotating speed of the inner barrel is about 650-800r / min, and the rotating speed of the motor is about 1450r / min. The realization of the above two functions is accomplished by a two-stage reduction device. The first stage is a belt drive with a reduction ratio of 1:1.8, which converts the speed of the output shaft of the motor at about 1450r / min to the speed of the input drive shaft of the reducer at about 800r / min. min, and is connected to the shaft of the inner tub through ...

AI Technical Summary

Problems solved by technology

[0007] 1. The gear transmission device used is open and soaked in the washing liquid. The gears and gear shafts are easy to adhere to dirt, dust and cloth hair, which will increase the wear and shorten the service life.

[0008] 2. The motor directly drives the inner barrel to rotate without deceleration. Whether the frequency conversion motor or the DC motor is used, there is a problem that the output power of the motor is small at low speed. Only under the condition of rated speed, the motor can output rated power. They are designed to work close to the rated speed, but not far away from the rated speed. Otherwise, a higher power motor will be used, which will increase the cost.
