Refrigeration device with gesture-controlled dispenser

A method of a dispenser of a refrigeration device, the method comprising:

• generating, with one or more ultrasonic sensors of the dispenser, measurement signals indicative of a hand positioned in a dispenser opening;
• detecting, with a control unit of the refrigeration device based on the measurement signals, a height of the hand in free-space within the dispenser opening;
• setting a requested fill height to the detected height of the hand within the dispenser opening;
• dispensing a substance into a container placed in the dispenser opening;
• and
• ceasing said dispensing in response to the substance in the container attaining the requested fill level;
• wherein detecting the height of the hand comprises:
• detecting, based upon the measurement signals, a palm of the hand within the dispenser opening and a relation of the detected palm to the container;
• and
• determining the requested fill height based upon the relation of the detected palm to the container.

• and
• ceasing said dispensing in response to the substance in the container attaining the requested fill level;
• wherein detecting the height of the hand comprises:
• detecting, based upon the measurement signals, a finger of the hand in the dispenser opening and a relation of the detected finger to the container;
• and
• determining the requested fill height based upon the relation of the detected finger to the container.

A refrigeration device, comprising:

• a refrigerated compartment;
• a door movable between a closed state that seals the refrigerated compartment and an opened state that grants access to the refrigerated compartment;
• a dispenser opening in an exterior surface of the door;
• a dispenser outlet in the dispenser opening;
• a reservoir configured to hold a substance;
• a conveyor configured to convey the substance from the reservoir to the dispenser outlet;
• one or more ultrasonic sensors configured to generate measurement signals that are indicative of a hand in the dispenser opening;
• and
• a control unit configured to measure, based on the measurement signals, a height of the hand in free-space within the dispenser opening, wherein the height of the hand is in relation to a bottom shelf of the dispenser opening, set a requested fill height to the measured height of the hand, generate signals that cause the conveyor to convey the substance from the reservoir to a container placed under the dispenser outlet, and cease conveying the substance upon the container attaining the requested fill level.
