Household refrigeration appliance with a power-saving mode, and method for initializing a household refrigeration appliance

A method for initializing a household refrigeration appliance after an activation thereof, wherein the refrigeration appliance includes:

• a cooling chamber and at least one door for closing off the cooling chamber;
• a controller;
• at least one door image recording module arranged on the at least one door and having at least one camera sensor and a gyro sensor;
• and
• at least one body image recording module arranged on a body of the refrigeration appliance and having at least one camera sensor;
• and wherein:
• each of the image recording modules is connected to the controller via a serial digital video interface and each has a serializer which is connected for data communication to a deserializer of the controller;
• and
• the controller, in addition to the deserializer, has a system master which is configured to receive information from at least one door opening switch indicating whether the at least one door is closed;
• the gyro sensor is configured to determine if the door is closed when the gyro sensor receives a message indicating that a door opening sensor assigned to the door has detected a closed state of the door and when a current angular velocity of the door determined by the gyro sensor reaches or undershoots a predetermined first threshold value;
• and
• the method comprising, after the activation of the household refrigeration appliance:
• activating the controller and the image recording modules;
• initializing the gyro sensor of the at least one door image recording module by the activated system master;
• if subsequently the system master receives information from the at least one door opening switch, indicating that the at least one door is open or has been closed:
• transmitting the information from the system master to the gyro sensor of the at least one door image recording module, and thereupon deactivating the associated serializer;
• and
• following a transmission of the information, deactivating with the system master the at least one body image recording module and the deserializer and then transitioning into a power-saving mode.

A method for waking up a household refrigeration appliance for recording an image, wherein the household refrigeration appliance has

• a cooling chamber and at least one door for closing off the cooling chamber;
• a controller,
• at least one door image recording module arranged on the at least one door and having at least one camera sensor and a gyro sensor;
• and
• at least one body image recording module arranged on a body of the refrigeration appliance and having at least one camera sensor;
• and wherein:
• each of the image recording modules is connected to the controller via a serial digital video interface and each has a serializer which is connected for data communication to a deserializer of the controller;
• and
• the controller, in addition to the deserializer, has a system master which is configured to receive information from at least one door opening switch indicating whether the at least one door is closed;
• the gyro sensor is configured to determine the door is closed when the gyro sensor receives a message indicating that a door opening sensor assigned to the door has detected a closed state of the door and when a current angular velocity of the door determined by the gyro sensor reaches or undershoots a predetermined first threshold value;
• and
• the method comprises:
• with the at least one door being closed, the system master being in a power-saving mode, the at least one body image recording module and the deserializer being deactivated, and the serializer of the at least one door image recording module being deactivated,
• waking up the system master upon receiving information from at least one door opening switch indicating that the at least one door is open;
• upon having been woken up, activating with the system master the at least one body image recording module and the deserializer;
• and
• activating with a gyro sensor of a door image recording module an associated serializer if the gyro sensor detects that the associated door is being opened.
