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.

An oven includes a collision area in which air circulating inside a cooking compartment is collided to reduce the pollution inside of the cooking compartment. A collision area may collectively collect an oil mist condensed by the collision of the air. The collision area is disposed on the side where the flow of air is changed to induce air collision and guide the air to the front side of the cooking compartment to increase air circulation and increase ease of cleaning inside the cooking compartment.

A cooking appliance including a cleaning environment provided to be able to easily remove contaminants inside the cooking appliance by heating the inside of a cooking room to a temperature for amorphization of the contaminants, and method for controlling the same. The cooking appliance includes a main body configured to have a cooking room; a steam generator configured to supply steam to the cooking room; a water supplier arranged in the main body and configured to store water; and a pump assembly configured to supply water to the steam generator and the cooking room from the water supplier.

A multi-compartment oven provides in-place cleaning through the use of distributed spray nozzles possibly augmented by steam, fan blowing, and heat from other components of the oven. A centralized draining system allows recycling of the water without breaching the separation between the cooking compartments.

A door for a self-clean cooking appliance, such as an oven, is constructed to maintain a low external surface temperature during high temperature operations within the appliance. The door includes three glass panes in spaced apart relation where the spacing between an outermost glass pane and a central glass pane is greater than the spacing between an innermost glass pane and the central glass pane.

A grease and food particle trap for use with an oven shooter tube cleaning system that provides improved resistance to clogging and improved maintenance better matching the ability of the shooter tube cleaning system to provide complete cleaning and removal of grease and food particles is provided. An auxiliary heating system may provide improved energy efficiency and temperature control for cleaning operation by separately heating the cleaning solution upstream from the shooter tube prior to delivering a cleaning spray to the cooking volume.

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.

In a method for carrying out a cleaning procedure for a cooking appliance, a first tank of the cooking appliance is filled by a user with water. A first portion of water in the first tank is moved into a buffer store and then moved from the buffer store into a cooking chamber to provide a first treatment agent therein. The first treatment agent remains in the cooking chamber for a first time period. A second portion of water in the first tank is moved into the buffer store and the first treatment agent is moved into the first tank. The second portion of water in the buffer store is into the cooking chamber to provide a second treatment agent in the cooking chamber. The second treatment agent remains in the cooking chamber for a second time period and the second treatment agent is then moved into the first tank.
