Refrigerator appliance and sound emitting device and method for operation

A refrigerator appliance, comprising:

• a cabinet forming a refrigeration compartment, a freezer compartment, or both;
• a door attached to the cabinet, the door configured to selectively allow entry to the refrigeration compartment, the freezer compartment, or both;
• a dispenser assembly positioned at the door, the dispenser assembly comprising a recess extending into the door, the dispenser assembly configured to egress a fluid, ice, or both, toward the recess;
• a scanner assembly comprising a scanner device and a targeting device, wherein the scanner assembly is positioned at a casing disposing the scanner device and the targeting device at an angle toward the recess and behind the external wall, wherein the scanner device and the targeting device are positioned at the angle toward the recess and behind the external wall;
• and
• a controller communicatively coupled to the scanner assembly and the sound emitting device, the controller configured to execute instructions that causes the refrigerator appliance to perform operations, the operations comprising:
• commanding provision of light toward or from the recess when the targeting device detects a presence of an object at the recess;
• commanding, at the scanner device, measuring fidelity of scan data from light reflected from the object at the recess;
• commanding provision of light toward or from the recess after a pre-determined period of commanding measurement of fidelity of scan data;
• and
• transmitting a scanner control signal commanding a scanner audible output when the pre-determined period of commanding measurement of the amount and pattern of light at the scanner device is complete.

A method for reading a machine-readable code at an object at a refrigerator appliance, the method comprising:

• providing, from a lighting component of the refrigerator appliance directed toward or from a recess at a dispenser, light toward the recess when a targeting device or a proximity sensor detects a presence of an object at the recess;
• scanning, via a scanner device, a machine-readable code at an object at the recess;
• and
• transmitting a scanner control signal commanding a scanner audible output when a pre-determined period of commanding measurement of fidelity of scan data at the scanner device is complete.
