Abstract: Disclosed is a heating cooker suitable for cooking fish, meat, or the like, and preventing smell or smoke from being released when the cooking chamber is opened. The disclosed heating cooker comprises an enclosed cooking chamber having at least one heating element contained in the enclosed cooking chamber and a ventilation chamber having an inlet passage and an outlet passage. The cooking chamber is connected to the cooking chamber via the inlet and outlet passages allowing air to circulate between the ventilation chamber and the cooking chamber. A fan and a spraying unit may be disposed in the ventilation chamber wherein the fan is operable to circulate air between the cooking chamber and the ventilation chamber, and the spraying unit is operable to spray water from a reservoir adjacent to the ventilation chamber to intercept smell or smoke contained in air in the ventilation chamber.

Abstract: This invention relates to a wet type centrifugal ‘filter less’ air cleaner. The air cleaner includes a housing having a scrubbing room associated with an air inlet and a vortex room associated with an air outlet. A reservoir is in fluid communication with the housing for supplying washing water to the air cleaner. An atomizer is in cooperation with the reservoir for producing atomized washing water to form a wet air mixture in the scrubbing room so that the atomized washing water collects the contamination in the air. A centrifugal impeller is disposed in the housing for drawing in air to create a centrifugal force on the wet air mixture. As the wet air mixture flows through the vortex room the centrifugal force separates the contaminated washing water from the purified air because of the difference between the specific gravities of the air and the washing water.
