Abstract

The invention relates to a control method of a washing machine and particularly a method for identifying stain types of clothes and choosing corresponding washing control methods. The method specifically comprises the steps of weighing a washing machine system, scanning the clothes by using a near infrared spectral sensor, obtaining a spectral value U0, comparing the U0 with a preset wave band, and choosing a corresponding washing method according to a comparison result. According to the technical scheme, the dirtiness degree of the clothes to be washed is detected automatically, based on the weight of the clothes, parameters such as the washing dose, the washing time and the washing intensity are chosen and added automatically through a computer board, the washing efficiency and the intelligent level of the washing machine are improved.

Description

A kind of method of the identification clothes stains kind for washing machine

Technical field

The present invention relates to a kind of control method of washing machine, be specially after identification clothes stains kind, then select corresponding control method for washing.

Technical background

At present, most of automatic washing machines, when laundry, are all in washtub, to add after clothing, manually select a clothing material program on computer board.According to clothing material, the preset wash time of weight computer board, wash intensity again, washing agent addition and rinsing number of times etc. washs action.

Owing to needing at every turn, the clothes stains kind of washing is different, and different types of spot is selected same mode of washing, easily causes slight dirty clothing can suffer excessive washing, and clothing bears unnecessary wearing and tearing, and causes water, electricity, and the waste of washing agent; And more dirty clothing can cause and do not wash clean, this also causes the low of washing machine intelligent level, can not accomplish real full-automatic.

Summary of the invention

For the deficiencies in the prior art, the invention provides a kind of washing machine that can automatically identify the method for clothing degree of fouling and there is this function.This washing machine can be identified clothes stains kind and the degree of fouling that will wash automatically, and can regulate wash time according to clothes stains kind and degree of fouling, washing intensity, and washing agent addition and rinsing number of times etc., improve washing efficiency.Technical scheme of the present invention is achieved in that

This washing machine has near infrared light spectrum sensor, and infrared spectrum sensor is placed on washing machine bung place, by wire, is connected with the computer board of washing machine.

A method for the identification clothes stains kind of washing machine, specifically comprises the following steps:

(1) washing clothes is put into inner tank of washing machine, after washing machine is weighed, use near infrared light spectrum sensor to scan clothing, obtain spectral value U0;

(2) wave band default in U0 and computer board of washing machine is contrasted, described default wave band comprises whole wavelength band of near infrared spectrum, and segmentation is with the spectral band of the various spots of correspondence;

(3) according to the spot kind of comparing result identification clothing, select corresponding washing mode.

Described default wave band divides 5 sections, is respectively U1 ~ U5, and U1 wave band is at 780-1000nm, and U2 wave band is at 1000-1400nm, and U3 is at 1400-1800nm, and U4 is at 1800-2200nm, and U5 is at 2200-2526nm.

Spots recognition method is:

The corresponding relation U1 of spectral band scope: grease class is main spot composition, U2: sweat stain class is main spot composition, U3: food class is main spot composition, U4: bloodstain class is main spot composition, U5: other and mixed type spot.U0 is within the scope of U1, and grease class is main spot composition, and wash time can increase by 3 minutes, and detergent amount increases 3ml by per kilogram clothing, many 5 minutes of rinsing program, and other programs are normal;

U0 is within the scope of U2, and sweat stain is main spot composition, and wash time can reduce 3 minutes, and detergent amount reduces 2ml by per kilogram clothing, and other programs are normal;

U0 is within the scope of U3, and food class is main spot composition, and washing machine can increase by 5 minutes soak times before washing procedure, and other programs are normal;

U0 is within the scope of U4, and bloodstain class is main component, and wash time can increase by 10 minutes, and detergent amount increases 5ml by per kilogram clothing, and other programs are normal;

U0 is within the scope of U5, and all programs of washing machine are all normal.

By such scheme, the present invention is by automatically detecting the spot kind of washing clothes, and computer board selects to add detergent amount automatically in conjunction with clothes weight, and the parameters such as wash time, washing intensity, improve washing efficiency, improve the intelligent level of washing machine.

Accompanying drawing explanation

Fig. 1 is flow chart of the present invention.

The specific embodiment

In computer board of washing machine, set in advance the corresponding relation of spectral band scope corresponding to various spots: U1, U2, U3, U4, U5, above wave band comprises whole wavelength band of near infrared spectrum.U1 wave band is main spot composition in 780-1000nm grease class, U2 wave band is main spot composition in 1000-1400nm sweat stain class, U3 is main spot composition in 1400-1800nm food class, U4 is main spot composition in 1800-2200nm bloodstain class, and U5 is in 2200-2526nm other and mixed type spot.

With reference to the accompanying drawings 1, identification clothes stains kind class methods are:

1) washing clothes is put into inner core, start washing machine, driven by motor inner core rotates, and near infrared light spectrum sensor scans clothing simultaneously;

2) near infrared light spectrum sensor obtains corresponding wave band U0 after clothing is scanned, and imports computer board into, and the numerical value obtaining and default wavelength band are compared;

3) according to comparing result, select corresponding mode of washing to wash clothes:

U0 is within the scope of U1, and grease class is main spot composition, and wash time can increase by 3 minutes, and detergent amount increases 3ml by per kilogram clothing, many 5 minutes of rinsing program, and other programs are normal;

U0 is within the scope of U2, and sweat stain is main goods and materials composition, and wash time can reduce 3 minutes, and detergent amount reduces 2ml by per kilogram clothing, and other programs are normal;
