Detailed Description
The following describes embodiments of the present application in further detail with reference to the accompanying drawings.
The washing control method provided by the application is shown in fig. 1 and comprises the following steps:
step S11: a first pH of the wash water is obtained.
Put into the clothing in the user to washing machine, select washing program and start the back, begin to intake to first preset water level, stir and predetermine the time after and determine the clothing material based on the change of water level value, for example wool, chemical fibre, cotton-flax etc. and later intake to the second preset water level, stir the washing, stir the certain time after, detect the pH value of wash water through the pH value sensor of urceolus bottom installation: a first pH value.
Step S12: and judging whether the first pH value is smaller than a set threshold value.
Taking the threshold value of 8 as an example, it is determined whether the first pH value is less than 8, that is, whether the alkalinity of the current washing water is suitable for the decomposition of the liquid detergent, and if the alkalinity is less than 8, it indicates that the acidity and alkalinity of the current washing water are not suitable for the decomposition of the hydrogen peroxide, then
Step S13: the heating mode is turned on.
Here, the heating mode is a heating washing mode of the washing machine, or a heating pipe is simply turned on to heat washing water, or a drying mode is turned on to blow hot air to the inner tub based on an operation characteristic of the drying mode, and so on. After the heating mode is started, the temperature of the washing water rises, and the decomposition of the hydrogen peroxide is accelerated when the temperature of the washing water rises because the decomposition of the hydrogen peroxide is greatly influenced by the temperature, so that the pH value of the washing water is promoted to rise.
In the heating mode, a default heating temperature can be set, or a heating minimum value can be determined according to the season information, for example, in winter, the heating minimum value is 20 degrees, in summer, the heating minimum value is 30 degrees, and the heating mode is started at the determined heating minimum value.
Before the heating mode is started, a step of judging whether the heating mode is started exists, if the heating mode is started, the heating mode is not required to be started again, heating is carried out according to the preset temperature, and the following steps are continued.
Step S14: and acquiring a second pH value of the washing water after the first set time, and judging whether the second pH value reaches a set threshold value.
After the heating mode is started for the first set time, the pH value of the washing water is detected for the second time, namely whether the second pH value reaches the set threshold value or not, if so, the pH value is detected for the second time
Step S15: the heating mode is turned off and the washing process is continued. If the pH value does not reach the set threshold value of 8 after the heating for the first set time
Step S16: the heating temperature of the heating mode is adjusted up to the set temperature.
On the basis of the current heating temperature, the heating temperature is increased to a set temperature, the washing water is continuously heated, and the hydrogen peroxide in the detergent is promoted to be decomposed, wherein the set temperature can be a preset fixed value.
In step S11, if the material of the clothes is determined based on the change of the water level value, an appropriate set temperature can be determined according to the material of the clothes when the heating temperature is adjusted, so as to ensure that the clothes made of the specific material is heated within the acceptable water temperature range.
Step S17: the heating mode is turned off after the second set time and the washing process is continued.
After the heating is continued for the second set time, the heating mode is closed and the washing program is continued without detecting the pH value; the purpose of this step is to heat the temperature of the washing water as much as possible under the condition of the limitation of the material of the clothes or other conditions to promote the decomposition of the hydrogen peroxide in the detergent as much as possible, so as to achieve the technical effect of improving the washing effect as much as possible.
