Latest Patents
Shi Zhijun holds a patent for a method of operating a BLDC motor in an ice making appliance. This invention involves an icemaker that includes a casing receiving water from a supply, which is in thermal communication with an evaporator of a sealed system that chills the casing to freeze the water. An auger is mounted within the interior volume and is rotatable to scrape the ice from the casing and urge it through an extruder to form nugget ice. The BLDC motor is mechanically coupled to the auger to selectively rotate it. A controller determines a target speed of the auger based on ice production parameters and operates the BLDC motor accordingly. This innovative design ensures constant speed and sufficient torque to prevent the ice maker from freezing.
