Embodiment two：
How the washing machine for just specifically describing the present invention below realizes detection bacterium breeding amount.Using data obtaining module as temperature
Illustrate exemplified by degree sensor and relative humidity sensor.
A kind of method of use in washing machine detection bacterium breeding amount, is performed, information obtains on the washing machine described in embodiment one
Modulus block is temperature sensor and relative humidity sensor, and washing machine is upper after once washing procedure terminates, the control of washing machine
T just obtains once real-time temperature, relative humidity to system by temperature sensor and relative humidity sensor at regular intervals
Value, and is saved, and after T time, control system obtains n times temperature, rh value altogether, control system by n times temperature,
Rh value and the temperature of the appropriate bacterial breeding that is prestored in control system, compared with rh value, if n times temperature,
Rh value at least K% number falls in the temperature to prestore, in the range of rh value simultaneously, and T is more than control system
In setting value T1, then start sterilization procedure or remind user need it is degerming and by user be confirmed whether start sterilization procedure.
Temperature, the rh value scope of the appropriate bacterial breeding to be prestored in control system are mould with harm to the human body maximum
Bacteria growing condition is standard, and temperature range is 25~30 DEG C, and RH range is that 65%~90%, T1 is the fungus growth cycle
The middle time into exponential phase, T1=6~8 hour.
Time t is 0.5~1 hour, and it is secondary equal that control system obtains temperature, the time interval of rh value t time, that is, controls

Bacterium program, K% be 100% when, only all temperature, rh value all simultaneously fall prestore temperature, rh value model
Enclosing the interior sterilization procedure or prompting user of just starting needs degerming and is confirmed whether to start sterilization procedure by user.
For example, t=1 hours, K%=50%, N=8, then the control system of washing machine every 1 hour just by TEMP
Device and relative humidity sensor detection once real-time temperature, rh value, and save, the control system of washing machine are total to
After have recorded 8 temperature, rh values, it is assumed that there are 6 temperature, rh value to fall the temperature in the suitable mould breeding to prestore
In the range of degree, rh value, that is, there are the temperature of 75% number, rh value to fall the temperature in the suitable mould breeding to prestore
Degree, in the range of rh value, more than 50%, and time of 8 hours have also exceeded and enter exponential phase in the fungus growth cycle
Time, therefore control system judges the environment appropriate bacterial growth in steel ladle, and by the breeding of 8 hours, having reached needed
Degerming standard is wanted, therefore, starts sterilization procedure, or reminds user that needs are degerming.
Under conditions of same, if the control system of washing machine have recorded 8 temperature, rh values, only 3 temperature altogether
Degree, rh value fall in the temperature of the suitable mould breeding to prestore, in the range of rh value, i.e. only 37.5% number
Temperature, rh value fall in the range of the temperature of the suitable mould breeding to prestore, rh value, less than 50%, then control
System judges that sterilization procedure need not be started.
