And S12, when the water temperature in the inner barrel detected by the temperature measuring device reaches the preset scalding temperature and/or the air pressure variation in the inner barrel in the preset unit time reaches the preset air pressure variation, the current temperature of the washing machine reaches the target heating temperature.
When the water temperature in the inner drum reaches the preset scalding temperature, the clothes can be scalded; when the air pressure detection device is in the preset unit time, the air pressure variation in the inner barrel reaches the preset air pressure variation, and the clothes can be scalded and washed.
Specifically, a large amount of steam can be generated when the water in the inner barrel boils, at the moment, the air pressure variation in the inner barrel can be obviously changed in the preset unit time, and whether the water in the inner barrel boils can be detected by detecting whether the air pressure variation in the inner barrel reaches the preset air pressure variation in the preset unit time. Therefore, as long as the water temperature in the inner cylinder detected by the temperature measuring device reaches the preset scalding temperature, or whether the variation of the air pressure detected by the air pressure detecting device in the preset unit time reaches the preset air pressure variation, or the water temperature in the inner cylinder detected by the temperature measuring device reaches the preset scalding temperature, and meanwhile, when the variation of the air pressure detected by the air pressure detecting device in the preset unit time reaches the preset air pressure variation, the current temperature of the washing machine reaches the target heating temperature.
According to the control method of the washing machine, water in the inner barrel of the washing machine is heated, when the temperature measuring device detects that the water temperature in the inner barrel reaches the preset scalding temperature and/or the air pressure variation in the inner barrel reaches the preset air pressure variation in the preset unit time, the current temperature of the washing machine reaches the target heating temperature, the heating process of the washing machine can be protected through double protection, the risk of dry burning caused by the fact that the target heating temperature cannot be reached for a long time in a high altitude area is prevented, and the purposes of sterilizing and disinfecting clothes are achieved.
