Technical Field

The invention relates to the technical field of washing machines, in particular to a control method of a washing machine and the washing machine.

Background

At present, with the increasing demands of consumers for laundry sterilization and disinfection, a trend is also being made for washing machines with heating and ironing. The existing washing machine only depends on the temperature measuring device to detect the water temperature of the inner barrel of the washing machine, because the boiling points of the washing machine are different in different regions, if the water temperature of the inner barrel of the washing machine is detected only through the temperature measuring device in a high altitude region, when the preset temperature is higher than the boiling point temperature, the washing machine can be heated all the time because the detected water temperature does not reach the preset temperature, and the risk of dry burning is easy to occur. For the stability and the safety of the whole machine, some scalding procedures can not set the temperature too high, if the preset temperature is lower than the boiling point temperature, the clothes can not be scalded by steam, and further the clothes can not be sterilized and disinfected. Therefore, it is highly desirable to design a control method for a washing machine, which can not only sterilize and disinfect the clothes, but also prevent the risk of dry burning of the washing machine.
