Abstract: A cooking apparatus is disclosed. The cooking apparatus includes an apparatus body, a cooking chamber defined in the apparatus body for cooking food, and a door for opening and closing the cooking chamber. The cooking chamber has an inner wall surface-treated by plasma.

Abstract: A cooking apparatus for assuring easier cleaning of contaminants, such as food residue, attached to the wall surface of a cavity in the cooking apparatus is disclosed. The cooking apparatus includes a body defining the outer appearance of the cooking apparatus, and a cavity defining a space for heating and cooking an object and having an inner surface to form an oil-repellent surface by being heated. In a cleaning method for the cooking apparatus, the inner surface of the cavity is heated prior to cooking food, to have an oil-repellency. The inner surface makes it difficult for the contaminants to be attached thereto. Even if the contaminants are attached, the contaminants have a very low adhesive power and thus are easy to clean.

Abstract: A voice control apparatus of a vacuum cleaner includes: a sense signal detector for detecting a sense signal provided from a user to provide a voice recognizable environment in an ambience; a voice command recognizing unit for temporarily stopping a driving of a motor upon receiving the detected sense signal and, at the same time, outputting a voice command control signal previously set in a voice command set corresponding to a voice command instructed by the user; and a driving command controller for controlling a function and a mode of a vacuum cleaner upon receiving the voice command control signal. By providing a voice recognizable environment, the vacuum cleaner can be effectively controlled through a user's voice command even in an environment with a strong noise.

Abstract: An air purifying robot and its operation method capable of purifying air using a mobile robot are disclosed. To this end, an air purifying robot comprises: a main body casing having a certain space therein, and provided with a suction hole for sucking ambient air and a discharge hole for discharging the purified air; a fan motor installed in the main body casing, and rotating so as to suck the ambient air of the main body casing through the suction hole; a dust collecting filter for filtering pollutants contained in the ambient air having been sucked through the suction hole; main wheels installed at a lower surface of the main body casing at a certain interval therebetween, and driven by the motor; an auxiliary wheel installed so as to maintain a horizontal state of the main casing, and moving the air purifying robot together with the main wheels; and a control unit for controlling the fan motor, the dust collecting filter and the main wheels.

Abstract: A water circulation cleaner is provided which is capable of easily removing contaminants on a cleaning object through the use of an improved suction head. A plurality of injection nozzles are used to spray cleaning water onto a surface of an object to be cleaned, and a suction port then sucks debris and fluid off of the surface of the cleaning object. An impeller assembly is used to generate this suction force, while a filter device removes debris contained in the suction fluid from the cleaning water. A brush and a duster may be affixed to a lower surface of the suction area of the cleaner, and can be used either alone or in combination to loosen debris from the surface of the object to be cleaned, thus facilitating removal by suction of the debris, and the effective and efficient cleaning of the object.

Abstract: In a suction system of a cleaner, by including at least two brushes rotatively installed at a certain side of a suction hole formed at the bottom surface of a cleaner body so as to be connected to a suction pipe and suck dust and filth on a floor; and driving units for rotating the brushes separately, although a size of filth is big or there are lots of filth, it is possible to clean it sufficiently, and accordingly a cleaning performance can be improved.
