S2: the temperature in detection dish-washing machine is to obtain initial temperature.
That is, the temperature in dish-washing machine can be detected before heater heats, and using the temperature that now the detects initial temperature as dish-washing machine.
Wherein, the temperature in dish-washing machine is detected by temperature sensor original in dish-washing machine.
S3: control heater and washings are heated until the temperature in dish-washing machine reaches target temperature according to predetermined power.
Wherein, the difference between target temperature and initial temperature is that preset temperature is poor.That is, controlled refrigerating/heating apparatus heats washings according to predetermined power until the temperature rise in dish-washing machine reaches preset temperature difference.In other words, target temperature can be obtained according to preset temperature difference and initial temperature.
Specifically, in the process that control heater heats washings, also can detect the temperature in dish-washing machine, and judge whether the temperature in dish-washing machine reaches target temperature, if so, then heater stop heating is controlled, if not, then control heater and proceed heating, and continue to judge the temperature in dish-washing machine.
