The invention provides a temperature measurement calibration method and a temperature measurement calibration device for household appliances, wherein a calibration function is arranged on the household appliances, the AD value corresponding to each degree of centigrade (the temperature AD/100 ℃ of boiled water) is calculated by taking the temperature AD value when water is boiled as a reference, and then the AD value corresponding to each degree of centigrade is used for correcting the AD value corresponding to each degree of centigrade set in the original program and is stored again, so that the temperatures of different users in the temperature setting function or the protection are basically consistent when the different users use different cookers.
Fig. 1 is a flowchart of a temperature measurement calibration method for a household appliance according to an embodiment of the present invention. As shown in fig. 1, in an embodiment, the thermometric calibration method includes the following steps:
step S10: controlling a household appliance to heat water;
step S11: testing the temperature AD value of the household appliance when water is boiled; and
step S12: and calculating the AD value corresponding to each degree centigrade according to the temperature AD value when the water is boiled, and updating the AD value corresponding to each degree centigrade stored in the household appliance according to the AD value corresponding to each degree centigrade.
Domestic appliance is when heating the pan, and the different temperatures that the pan reached are in correspond different temperature AD values in the domestic appliance, just the pan that domestic appliance heated different materials reaches the same temperature and is in also correspond different temperature AD values in the domestic appliance, wherein, temperature AD value is the value that singlechip converts temperature detection circuit's voltage signal into digital signal in the domestic appliance. In the temperature measurement calibration method provided by the first embodiment of the present invention, taking a case that a household appliance heats water, an AD value corresponding to each degree celsius is calculated by detecting an AD value of the heated water when the water is boiling, and then the AD value corresponding to each degree celsius stored in the household appliance is updated according to the AD value corresponding to each degree celsius, and the updated AD value corresponding to each degree celsius is used for performing control work, and when cookware made of different materials is replaced, the operation steps in the embodiment are repeated.
