Definitions

  • the present invention relates generally to refrigeration appliances and ice making assemblies, and more particularly to features and methods for cleaning ice making assemblies (eg, within refrigeration appliances).
  • Some refrigeration appliances include ice makers. To create ice, liquid water is directed to an ice maker and frozen. Depending on the specific ice maker used, many types of ice can be produced. For example, some ice makers include a mold body for receiving liquid water. An auger within the mold body can rotate and scrape ice from the inner surface of the mold body to form ice cubes. This type of ice maker is often referred to as a block ice maker. Certain consumers prefer block ice makers and their associated ice cubes.
  • Ice cubes are usually stored at temperatures above the freezing temperature of liquid water to preserve the texture of the ice cubes. When stored at such temperatures, at least a portion of the ice cubes will melt into liquid water. Typically, liquid water thus accumulates in the ice bucket of the ice making assembly. This can create many difficult or undesirable situations for refrigeration appliances. For example, every time some liquid water freezes, it causes parts of the ice to freeze together, making it difficult to dispense the ice. Also, liquid water may damage or adversely affect electrical components such as electric motors. Additionally, liquid water can be difficult to remove and, in some cases, can drip or flow from the ice dispensing portion of the refrigeration appliance.
  • a method of cleaning an ice making assembly may include positioning a cleaning cartridge containing detergent along a fluid path between the ice maker and the fluid storage volume, and initiating a flow of water to the fluid storage volume.
  • the method may further include directing a flow of overflow water to the ice maker and directing water from the ice maker to a cleaning cartridge to generate a cleaning solution.
  • the method may further include: forcing the cleaning solution through the fluid storage volume to the ice maker, and opening a drain line downstream of the cleaning cartridge between the fluid storage volume and the ice maker to direct the cleaning solution out of the fluid path.
  • a refrigeration appliance may include a case, an ice making assembly, and a controller.

  • a controller may be in operative communication with the ice making assembly.
  • the controller may be configured to initiate a cleaning operation comprising: initiating a flow of water from the water supply conduit to the fluid storage volume, directing a flow of overflow water to the ice maker, directing water from the ice maker along the fluid path to the cleaning cartridge, To generate the cleaning solution, force the cleaning solution through the fluid storage volume to the ice maker, and open the drain line to direct the cleaning solution away from the fluid path.
