Abstract

A method and system for providing washing machine operation information. The system comprises an input unit for inputting a command for washing machine operation control from a user, a controller for generating an operation control signal in response to the command inputted by the input unit to control the operation of a washing machine, and processing data regarding a use history and abnormal state of the washing machine, an operation drive circuit for driving a washing tub in the washing machine and supply/discharge of wash water in response to the operation control signal from the controller, a communication unit for supporting a communication function to transmit and receive the data processed by the controller externally over a communication network, a service provider connected to the communication unit for collecting the data from the controller, comparison-analyzing the collected data and generating control information for the setup of an optimum washing environment of the machine as a result of the analysis, and an output unit for externally displaying the control information from the service provider and its result processed by the controller. A using pattern of the user or an abnormal state of the washing machine is sensed and managed online, thereby improving the reliability and performance of the machine.

Claims

1. A method for providing washing machine operation information, comprising the steps of:

a) additionally providing a communication function in a washing machine to enable external data transmission and reception;

b) constructing a service provider for collecting and storing usage and operation history data of the washing machine, analyzing blocks of data covering pre-set periods of time and generating control information to control the operation of the washing machine, based on said analyzing;

c) allowing said service provider to collect said data regarding said washing machine from said machine;

d) allowing said service provider to generate said control information on the basis of the collected data and transmit the generated control information to said washing machine; and

e) outputting said control information transmitted from said service provider for external display to a user of said washing machine, enabling said user to modify a usage pattern and set up an optimum washing environment.

2. The method as set forth in claim 1, wherein said step b) includes the step of constructing said service provider in an online manner to allow said service provider to transmit and receive data to/from said washing machine over the Internet.

3. The method as set forth in claim 1, wherein said step c) includes the steps of:

c-1) connecting said washing machine to said service provider via said communication function; and

c-2) allowing said service provider to collect data about a use history and abnormal state of said washing machine from said machine.

4. The method as set forth in claim 3, wherein said step c-1) includes the step of connecting said washing machine to said service provider when a washing mode of said machine is started.

5. The method as set forth in claim 3, wherein said step c-2) includes the step of allowing said service provider to end the data collection from said washing machine when said washing mode of said machine is completed.

6. The method as set forth in claim 1, wherein said step d) includes the steps of:

d-1) allowing said service provider to arrange and store said data collected at said step c) in a database;

d-2) allowing said service provider to comparison-analyze said data stored in said database;

d-3) allowing said service provider to generate said control information in accordance with the analyzed result; and

d-4) allowing said service provider to transmit said generated control information to said washing machine.

7. The method as set forth in claim 6, wherein said step d-2) includes the step of allowing said service provider to periodically comparison-analyze said data stored in said database whenever a predetermined period of time elapses.
