An electrical cooking appliance with automatic cleaning of a cooking chamber is provided. The appliance may include a steam supply device configured to generate steam and supply the steam to the cooking chamber; a water supply pump that supplies water from a water tank to the steam supply device; a water discharge pump that collects condensed water from the steam supply device into the water tank; and a controller configured to activate the water supply pump to supply water to the cooking chamber to clean the cooking chamber; and activate the steam supply device to supply steam to the cooking chamber to clean the cooking chamber.

An interior material for cooking apparatus having good anti-staining and heat-resisting properties and strong surface intensity, easy to clean, and restorable from contamination, a cooking apparatus including the interior material therefor and method for removing stains from the interior material. The interior material for the cooking apparatus is formed of a coated layer including a silicon backbone and a fluorine functional group is formed on a base material.

A microwave oven cleaning assembly includes a cup that contains a cleaning solution. The cup is comprised of a microwave safe material to facilitate the cup to be heated in a microwave. Moreover, the cleaning solution is vaporized into a steam when the cleaning solution is heated above a boiling temperature of the cleaning solution. In this way the steam cleans an interior of the microwave oven. A disk is positioned on the cup and the disk is foraminous thereby facilitating the steam to pass through the disk. A protective sheet is removably bonded to the disk to inhibit the cleaning solution from evaporating. The protective sheet is removable from the disk when the cleaning solution is heated thereby facilitating the steam to pass through the disk.

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.

An oven with an enhanced structure to keep a cooking space clean includes a main body, a cooking chamber formed inside the main body and including a bottom wall, a burner provided at an outer lower part of the cooking chamber to heat up the cooking chamber, a door arranged to open or close the cooking chamber, a bottom plate coupled to the bottom wall of the cooking chamber with a gap from the bottom wall such that the bottom plate is located inside the cooking chamber, and an outlet for heated air formed between one end of the bottom plate facing the door and the bottom wall of the cooking chamber such that heated air generated from the burner is supplied to the door.

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.

In accordance with one aspect of the present invention, a heating device is presented. The heating device includes a pyrocatalytic, non-stick coating disposed on at least one surface. The pyrocatalytic non-stick coating includes (i) a binder derived from a silane, a polysiloxane, a polysilazane, or combinations thereof; and (ii) a catalyst dispersed within the binder, wherein the catalyst comprises a pervoskite crystalline material, a pyrochlore crystalline material, a spinel crystalline material, an ilmenite crystalline material, or combinations hereof.
