Benefits of technology

The present invention provides a washing machine and method that can quickly and efficiently reduce vibration during operation. The machine detects vibration data and calculates it, generating a control signal when it exceeds a set tolerance. The control panel then adjusts the motor and damping device accordingly to target vibration reduction. This results in a more effective and quick reduction of vibration in the washing machine.

Problems solved by technology

According to a survey of users' degree of satisfaction, noise of a washing machine draws users' maximum concerns, so manufacturers spend great effort in optimized design of vibration-reducing structures and suspension design by all means and achieve some effects.
However, this manner of reducing vibration only passively reduces vibration by optimizing the vibration-reducing structure and solves many forms of vibration in one fixed manner.
Therefore, these methods cannot efficiently reduce vibration of washing machines.

embodiment 1

[0020]The present invention provides a vibration-reducing washing machine. Referring to FIG. 1, the vibration-reducing washing machine comprises an outer drum 5, a cabinet 6, a motor 2, a main control panel 7, a damper device 3, and a vibration detection and control module fixed to the washing machine and connected to the main control panel, wherein the vibration detection and control module is configured to detect and calculate vibration data of the washing machine and generate a control signal. The vibration-reducing washing machine and the washing machine vibration reducing method according to the present invention are capable of detecting the vibration data during operation of the washing machine, performing calculation for the vibration data, and generating the control signal. As known from the above, the control signal is generated according to the calculation result of the vibration data, and using the control signal to perform vibration-reducing control for the washing machi...

embodiment 2

[0048]Corresponding to Embodiment 1, a roller washing machine is described as an example in Embodiment 2. Referring to FIG. 2, different from Embodiment 1, the mounting positions of the motor 2 and detecting unit 1 disposed on the roller washing machine both vary accordingly. In the roller washing machine, a rotation axis of a rotation shaft of the motor 2 is different from the pulsator washing machine. Although the motor is mounted at the bottom of the outer drum, the direction of the bottom of the outer drum here is different from the direction of the bottom of the outer drum of the pulsator washing machine. Briefly, the rotation shaft of the motor mounted at the bottom of the outer drum in the pulsator washing machine is perpendicular to the horizontal surface and the bottom of the outer drum is close to the ground surface; but the rotation shaft of the motor of the roller washing machine in the present embodiment may be parallel to the horizontal surface, with the bottom of the ...

Abstract

A vibration-reducing washing machine and a vibration-reducing method therefor. The washing machine has an outer drum, a cabinet, a motor, a main control panel, a damper device, and a vibration detection and control module fixed to the washing machine and connected to the main control panel. The vibration detection and control module detects and calculates vibration data and generates a control signal. The method includes setting a fixed tolerance for washing machine vibration, detecting and calculating vibration data, and comparing the vibration data with the fixed tolerance, and when the detected vibration data exceeds the fixed tolerance, adjusting working parameters of the motor and adjusting a damping magnitude of the damper device until the vibration data detected subsequently is maintained within the range of the fixed tolerance.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to the field of washing machines, and particularly to a vibration-reducing washing machine and a vibration-reducing method for a washing machine.BACKGROUND OF THE INVENTION[0002]According to a survey of users' degree of satisfaction, noise of a washing machine draws users' maximum concerns, so manufacturers spend great effort in optimized design of vibration-reducing structures and suspension design by all means and achieve some effects. However, this manner of reducing vibration only passively reduces vibration by optimizing the vibration-reducing structure and solves many forms of vibration in one fixed manner. Therefore, these methods cannot efficiently reduce vibration of washing machines.SUMMARY OF THE INVENTION[0003]The brief summary of the present invention is given below to provide basic understanding of some aspects of the present invention. It should be appreciated that this summary is not an exhaustive su...
