Single-barrel direct-drive full-automatic pulsator washing machine

Abstract

The invention discloses a single-barrel direct-drive full-automatic pulsator washing machine. The single-barrel direct-drive full-automatic pulsator washing machine comprises a base and a control system, wherein an outer shell is arranged on the base; a bearing seat used for sealing is arranged in the center of the bottom of the outer shell; a dewatering barrel is arranged in the outer shell; a gap is reserved between the dewatering barrel and the inner wall of the outer shell; the dewatering barrel is driven by a direct-drive motor; the direct-drive motor is arranged on the base and is positioned below the dewatering barrel; the control system is used for controlling the direct-drive motor to rotate forwards or backwards; the shaft end of an output shaft of the direct-drive motor is connected with a transmission shaft; a washing transmission mechanism, a dewatering transmission mechanism and a washing and dewatering conversion mechanism are arranged between the dewatering barrel and the direct-drive motor; a split-type speed reducing clutch device is also arranged between the dewatering barrel and the direct-drive motor; the split-type speed reducing clutch device comprises a speed reducer and a clutch mechanism; the speed reducer is centered, is arranged below the dewatering barrel and above the bearing seat used for sealing, and is sealed by a sealing ring. The single-barrel direct-drive full-automatic pulsator washing machine is high in transmission efficiency, small in vibration amount, simple in structure and is easy to install and maintain.

Description

technical field [0001] The invention relates to a fully automatic pulsator washing machine, in particular to a single-tub direct-drive fully automatic pulsator washing machine. Background technique [0002] At present, the fully automatic pulsator washing machines on the market all adopt the structural design method that the dehydration bucket part is installed in the outer tub part, and the outer tub part is suspended on the box body through the boom damping part, and its power drive device is mainly composed of a motor, a clutch And the belt connecting the two, the motor is installed on one side of the washing tub, and the clutch is driven by the belt for washing or dehydration. Such a fully automatic pulsator washing machine mainly has the following problems: [0003] 1. In terms of vibration reduction, the suspension type vibration reduction parts are used for vibration reduction, and at the same time, the power transmission mode of belt drive is adopted, so that the cen...

AI Technical Summary

Problems solved by technology

[0003] 1. In terms of vibration reduction, the suspension type vibration reduction parts are used for vibration reduction, and at the same time, the power transmission mode of belt drive is adopted, so that the center of gravity of the vibration reduction parts deviates from the center of the dehydration bucket inherently, resulting in low vibration reduction efficiency and energy consumption improve;

[0004] 2. Since the output shaft of the motor is placed side by side with the sub-shafts of the washing shaft and the dehydration shaft, during dehydration, the clothes are placed unevenly in the dehydration bucket, causing the center of gravity to not be at the center of gravity of the washing shaft, and the dehydration bucket is unbalanced, which is prone to vibration and noise;

[0005] 3. The belt drive has low efficiency, high failure rate, limited life, and noise during transmission, and the belt is easy to slip during washing;

[0006] 4. The clutch has a planetary gear reduction mechanism, the structure is complex, installation and maintenance are inconvenient, the efficiency is low, and the mechanical noise is large

[0007] In order to avoid the problems caused by the power drive device, some fully automatic washing machines driven by variable frequency motors have appeared on the market. Although this direct-drive power transmission method can avoid some of the above-mentioned technical problems, it also has the problems of high cost of the variable frequency motor, which is not easy to popularize, and the failure rate of the frequency converter and the motor is high, and the maintenance cost is high.
