Washing machine procedure function inspection device and method

Abstract

A program function test module for washer is composed of motor, water feeding valve and drain valve, etc. load, drive control unit for controlling motor and valves and reading out their current states, input keypad for inputting commands and setting to functions, memory for storing operation information, history and data, and data exchange interface and display. Its test method includes downloading the information about washer and relative test mode in memory, or inputting command, switching to test mode, and display operating state.

Description

technical field [0001] The invention relates to a washing machine program function checking device and method. Background technique [0002] Generally speaking, the washing machine is a machine that removes the stains in the laundry through the processes of washing, washing, and dehydration according to the set procedures. bucket) a fully automatic washing machine that rotates in the horizontal direction or a drum type washing machine that uses the vertical rotation of the drum. [0003] In order to meet the various requirements of different consumers, such washing machines have developed various washing procedures, functions, etc. and applied them to actual products. [0004] The washing machine of traditional technology design is as shown in Figure 1, comprises: direct or indirect rotary washing wheel, the motor 20 of outer bucket or inner bucket (washing bucket / dehydration bucket) and other loads 21 of water supply valve, drain valve etc.; Input keys 23 for inputting va...

AI Technical Summary

Problems solved by technology

[0020] First: Since the product’s operating status, use history, and failure history cannot be saved, the cause of the failure cannot be determined during repairs.

Therefore, only using the method of replacing parts, that is, using the method of replacing hardware to repair the product, the same failure will still occur

[0021] Second: The washing program cannot be changed by saving it in the ROM of the system control microcomputer, so it cannot solve the problem of the performance degradation of the washing machine caused by regional characteristics and changes in life patterns.
