Abstract: A fan motor for a vacuum cleaner includes a motor mount defining a cooling flow path inlet, an impeller, an impeller cover defining an air inlet, an air discharge opening defined at the motor mount and configured to discharge air to an outer space of the motor mount, and a cooling flow path outlet defined vertically above the motor mount. The cooling flow path inlet is configured to introduce air from the outer space of the motor mount into an inner space of the motor mount to cool the motor part, and the cooling flow path outlet is configured to discharge air from the inner space of the motor mount toward a space that is defined between the impeller and the air discharge opening based on the space between the impeller and the air discharge opening having a lower pressure than the inner space of the motor mount.

Abstract: A cooker including a first coating layer that is a general ceramic enamel layer and a second coating layer that includes phosphorus oxide-based components are coated on a surface of a cavity corresponding to the inner surface of the cooking chamber. Therefore, the inside of the cooking chamber can be more easily cleaned.
