A cleaning system for an oven having shelves which provide for distributed jets of heated air, allows water accumulation within the shelves during cleaning by reducing airflow through the shelf, and then provides rapid expulsion of the water in cohesive streams after accumulation to provide high inertial cleaning.

A method for detecting a cleaning need of a commercial cooking appliance with at least one cooking surface. The method includes the steps of capturing at least one image of at least a part of the cooking surface and/or at least a part of a cooking product, comparing the captured image of the part of the cooking surface with a prestored reference image of a contaminated cooking surface requiring cleaning and/or of the captured image of the part of the cooking product with a prestored reference image of the cooking product in a cooking status indicating a need for cleaning the cooking surface, and deciding, based on the result of the comparison, whether a cleaning is needed. A further aspect relates to a quality management monitoring system as well as a commercial appliance with a quality management monitoring system.

A cleaning insert for removable arrangement in a cooking space of a cooking appliance includes a receiving device for receiving a cleaning unit with a cleaning composition in a reversibly fixed manner, and a supporting body connected to the receiving device for positioning the receiving device relative to the cooking space.

A system 1 comprises a self-cleaning rotisserie oven 2 with a casing 4, a door 6, and an oven cavity 8, for cooking a food product. The system 1 further comprises a cleaning unit 10, which is a separate unit from the self-cleaning oven 2. The cleaning unit 10 comprises a frame 12, supporting a water tank 14, and a waste water tank 16. The frame 12 of the cleaning unit 10 is movably supported by wheels 18. The cleaning unit 10 comprises a push bar 20. The self-cleaning rotisserie oven 2 comprises a discharge hose connector 22, and a water hose connector 24, for connecting a discharge hose 26, and a water hose 28 respectively, to the cleaning unit 10. The self-cleaning rotisserie oven 2 further comprises a control 30 with a user interface, and a timer. The system 1 also comprises a second self-cleaning rotisserie oven 32.

An appliance and methods for operating the appliance in a safety-critical operation are provided. The appliance and methods for operating the appliance include features that provide safe and intuitive ways to initiate and cancel safety-critical operations performed by the appliance.

An oven includes a steam input arrangement with a thermal mass and one or more water flow directors to more effectively deliver water onto the thermal mass so that less water ends up bypassing the thermal mass.

A system for controlling the initiation of a cleaning process for an interior of an appliance may include a detection sensor and a processor in communication with the detection sensor. The detection sensor may be configured to generate detection sensor data based on a sensed condition in a field of detection of the detection sensor which may comprise one or more pre-determined locations. The processor may control the initiation of an appliance cleaning process. The appliance cleaning process may comprise receiving detection sensor data representative of a first time and a second time, generating an initial condition based on the received detection sensor data representative of the first time, and generating a new condition based on the received detection sensor data representative of the second time. The processor may be additionally configured to compare the initial condition and the new condition and determine if cleaning product is present.

A combination oven using non-caustic detergent during a cleaning wash cycle, along with the addition of a catalyst regeneration cycle after a predefined number of cleaning wash cycles, can regenerate the catalyst to restore nearly full function of the catalyst and removes most occlusion of the pores of the catalyst that occurs during oven cooking and cleaning wash cycles. The catalyst regeneration cycle includes a rinse agent cycle followed by a high temperature dry out and burnout step.
