Latest Patents

One of Liu's latest patents is a ventilation control method for a laundry device. This method involves acquiring the present current of an air inflow fan when it is started. It determines whether a water seal is formed by water in a water inflow pipe based on the present current. When the present current reaches a preset current value, it indicates that the water seal is formed. If the preset current value is not reached, it indicates that the water seal is not formed. If the preset current value is reached, the method releases the water seal by injecting water into the pipe to allow the water level to rise until the siphoning height is reached, triggering the siphon device to discharge the water in the pipe, followed by ventilating the drum assembly. If the preset current value is not reached, the method directly ventilates the drum assembly.

Another notable patent is for an integrated washer-dryer. This invention includes a box body, an inner and outer drum assembly installed in the box body, and a drying air duct provided between the box body and the drum assembly. A heat exchange device is also included in the drying air duct. The air inlet and outlet of the drying air duct are in communication with the drum assembly. The air inlet is configured with a first filter member, while a second filter member is provided between the first filter member and the heat exchange device. Additionally, a water spray nozzle is included within the drying air duct to wash off debris trapped on the first filter member.
