Embodiment Construction

[0015] The overall structure of the fully automatic washing machine in the embodiment of the present invention is as follows: figure 1 shown. In the outer box body 1 arranged on the base, a water bucket 3 is suspended freely through a suspender 2, and a washing and dewatering tank 5 with a rotary agitator 4 at the bottom is freely rotatable in the water bucket 3. The motor 6 and the tractor drain valve 13 which drive the agitator 4 or the washing and dewatering tank 5 through the deceleration clutch 7 are installed at the bottom of the water tank 3, and the top cover 9 is installed on the outer box body 1 and the water tank 3, and the top cover 9 The machine cover 10 that can be opened and closed freely is housed on it, and the program controller 12 and the water inlet electromagnetic valve 8 that the water level sensor 14, receives sensing signal and controls electrical appliances such as motor 6 are installed in the washing machine top cover 9. A safety switch 11 is arrange...

Abstract

A conversion driver wash machine. It contains system of wash and desiccation, drive gear applying revolute force to the system of wash and desiccation, induction motor driving the drive structure and its adjustable power. Adjustable power applies power as potential U1 and frequency f1 when the system of wash and desiccation is turned on or speed is increasing. After a certain time, apply U2 and f2(U1 / f1)> (U2 / f2).

Description

technical field [0001] The invention relates to an electric washing machine, in particular to a fully automatic pulsator washing machine with an adjustable power supply. In the International Patent Classification, it can belong to D06F33 / 02. Background technique [0002] The washing system of the washing machine drives the water flow in the reversible operation of forward rotation-stop-reverse-stop repeatedly, and then drives the clothes to move. The acceleration process at the start of each forward or reverse rotation causes the laundry to tumble in the washing liquid, which is crucial to the washing mechanism. The dehydration system usually has a resonance point of about 1 Hz and a (5-10) Hz. When dehydration is started, it is necessary to accelerate the rotation of the dehydration bucket to cross the two resonance points as soon as possible to avoid the occurrence of resonance. The washing system of the washing machine has a large frictional resistance torque, and the ...
