Filtered liquid circulation system for icemaker appliance
A recently granted patent (Publication Number: US11920847B2) discloses an innovative icemaker appliance designed with a unique filtration system. The appliance includes a cabinet with an ice storage compartment, an ice mold, a first reservoir for collecting liquid from the ice mold, and a gravity deionization filter suspended above the reservoir. A circulation system with a pump and nozzle dispenses liquid onto the filter, ensuring that only the top of the filter is used for filtration. The filter consists of layers of porous filtration material and deionization resin enclosed in a casing with openings for liquid flow.
Furthermore, the icemaker appliance features additional components such as a second reservoir for liquid circulation, a cleanout line with a valve for maintenance, and a sealed cooling system with an evaporator positioned at the ice mold. The appliance's design allows for efficient filtration of liquid used in ice production, ensuring high-quality ice output. With a focus on vertical filtration from top to bottom, the gravity deionization filter plays a crucial role in enhancing the overall performance of the appliance. The inclusion of a removable grate, collection tray, and return line further adds to the functionality and ease of use of the icemaker appliance, making it a promising innovation in the field of ice-making technology.
