Embodiment Construction

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, examples of which are shown in the accompanying drawings.

[0020] Fig. 1 is a plan view of a washing machine operating device according to the present invention.

[0021] As shown in Figure 1, the running device of the washing machine according to the present invention includes: a power supply part 1, which inputs alternating current (AC power); a conversion part 2, which converts the alternating current input through the power supply part into direct current; The converted direct current is smoothed; the inverter 4 generates a motor operation signal when converting the electric power smoothed into direct current; and the motor 5 is operated by the electric power input from the inverter.

[0022] It also includes: a control part 6, which generates a switching signal for controlling the power of the inverter 4, and inputs it into the inver...

Abstract

The operating apparatuses of a washing machine and the methods on that are renovated. The afore-mentioned washing machine is including: a memory that the reference signals are saved in order to operate a motor in a best condition according to each of the condition of the torque and noise; a control unit which generates the switching signals as calling the reference signals which are different each other according to the strokes of a washing machine, and comparing with the carrier signals; an inverter which generates a motor operating signal as an external power is switched by a switching signal; a motor which is rotated by a motor operating signal; and a revolving screen of a washing machine which is operated by a motor.

Description

technical field [0001] The present invention relates to a washing machine operating device and method, in particular to a washing machine operating device and method for keeping a revolving screen in an optimal rotating state according to the operating state of the washing machine and user requirements. Background technique [0002] Recently, a washing machine has spread to every household as a device for washing clothes and the like. This type of washing machine includes: a drum washing machine, which beats the clothes through the drum and washes them through the vibration force between the clothes and the washing water; a pulsator washing machine, in which the wave wheel rotates at the bottom of the washing machine, and the clothes are washed by the vibration force between the clothes and the washing water. Washing: Agitator washing machine, a pressurized water flow is generated by an agitator protruding to the inside of the laundry tray, and the clothes are washed by the ...
