  • Patent number: 11920289
    Abstract: A heating device of a clothes drying treatment device executes an on or off operation in a temperature interval. When the temperature in a drum reaches an upper limit value TDx of the temperature interval under an action of the heating device, the heating device is turned off and the heating device stops heating. The upper limit value TDx decreases as a number of off times x of the heating device increases. Accordingly, a higher initial off temperature is adopted for the heating device, the temperature in the drum rapidly increases to the drying temperature, a preheating time is shortened, and a certain coefficient is multiplied in following control parameters controlling on or off of the heating device. The coefficient is related to the number of on-off times, and the effect is achieved that the off temperature of the clothes dryer gradually decreases as the number of on-off times increases.

  • Patent number: 11891745
    Abstract: Washing appliance and a determination method for locking of a drum thereof. The washing appliance includes a drum for containing washing water, a drum motor for driving the drum to rotate and a locking structure for locking the drum. The drum motor drives the drum to rotate at a set power output, the locking structure generates a locking action for locking the drum, and until an output current of the drum motor is larger than a rated current, it is determined that the drum is locked by the locking structure; by comparing the output current of the drum motor with the rated current, until the output current of the drum motor is larger than the rated current. Whether the drum is locked by the locking structure or not can be accurately determined through the above determination, and therefore the drum locking accuracy can be improved.

  • Publication number: 20230407541
    Abstract: A ventilation control method for a laundry device to solve problems related to bacteria after clothes are washed in a laundry device, due to the moist interior of a drum assembly thereof. When an air intake fan is started, the present current of the air intake fan is acquired; if the present current of the air intake fan reaches a pre-set current value, water is injected into a water intake pipe to trigger a siphoning apparatus to discharge water from the water intake pipe, and a drum assembly is then ventilated; and if the present current of the air intake fan does not reach the pre-set current value, the drum assembly is directly ventilated. After clothes are washed, residual water inside a drum assembly can be air-dried, preventing breeding of bacteria and generation, and clothes are not subjected to secondary pollution during subsequent washes, thereby improving the user experience.
