Abstract: A complex type cleaner comprises: a body having either a dust collecting container for storing dust or a water collecting container for storing contaminated water; a fan motor installed at the body and generating a suction force; a suction head arranged at a lower side of the body, for sucking dust at the time of performing a vacuum-cleaning; a water tank mounted at the suction head, for storing cleaning water to be sprayed to a region to be cleaned at the time of performing a water-cleaning; and a suction nozzle integrally formed at the water tank, for sucking water contaminated after completing the water cleaning. The complex type cleaner reduces the number of components, reduces a fabrication cost, and has a water tank of a large capacity.

Abstract: A complex type cleaner includes: a body provided with a dust collecting container for storing dust; a fan motor installed at the body and generating suction force; a vacuum cleaning head disposed at a lower side of the body, into which dust is sucked in case the cleaner performs vacuum cleaning; and a water cleaning head mounted at the vacuum cleaning head, for spraying cleaning water onto a region to be cleaned, sucking contaminated water after completing water cleaning, and storing the sucked contaminated water, at the time of cleaning. By implementing both a vacuum cleaning function for sucking dust and a water cleaning function in one cleaner, there is provided a complex cleaner capable of reducing the cost, increasing convenience for use, and facilitating the keeping.

Abstract: A complex type cleaner includes: a body provided with a dust collecting container for storing dust; a fan motor installed at the body and generating a suction force; a vacuum cleaning head disposed at a lower side of the body, for sucking dust at the time of performing vacuum cleaning; and a water cleaning head mounted at the vacuum cleaning head, and provided with a suction head through which contaminated water is sucked at the time of performing water cleaning and a water collecting container for storing contaminated water sucked through the suction head. As a suction nozzle for sucking contaminated water and a water collecting container for storing the contaminated water sucked through the suction nozzle are integrally formed and installed at a suction head, there is provided a complex type capable of reducing the number of parts and a production cost, and employing a small capacity fan motor.

Abstract: A centrifugal fan, in which an expansion angle of a radius of curvature of the outer periphery of a scroll housing from a position angle of a cutoff portion, serving as a suction portion, to a designated portion from the former in the direction of air flow is gradually decreased; and an expansion angle of the radius of curvature of the outer periphery of the scroll housing from the above designated portion to a discharge portion is gradually increased, thereby easily converting the velocity of the discharged fluid to pressure due to the increased dimensions of the discharge region and increasing the flow rate. Further, since noise generated from a cutoff portion of the centrifugal fan of the present invention maintains the same level as that of the conventional centrifugal fan, the centrifugal fan of the present invention has reduced noise at the same flow rate.

Abstract: A complex type cleaner includes: a cleaner body having at least one of a dust collecting container for storing dust or foreign materials and a water collecting container for storing contaminated water; and a suction head having a dust suction opening disposed at a lower portion of the cleaner body and sucking dust when the cleaner performs a vacuum cleaning and a suction head having a suction nozzle for sucking contaminated water when the cleaner performs a water cleaning. By implementing both vacuum cleaning function for sucking dust and water cleaning function in one cleaner, a cost can be reduced, users' convenience can be improved, and the cleaner can be conveniently kept in storage.

Abstract: A combined microwave oven and hood is provided. The combined microwave oven and hood includes a cavity assembly including a cavity and an electronic equipment room disposed at one side of the cavity, a blower for generating an absorptive power of contaminated air, a filter for filtering the contaminated air absorbed through the blower, and a drawer type air curtain module, which is transferred to a front side of the cavity assembly as operated.

Abstract: Disclosed is a combination hood microwave oven, by which a room environment is maintained more pleasant and fresh by proving a microwave oven with an air curtain generating unit for preventing polluted air, which includes hot, smelling, or humid air produced from an oven range on cooking, from diffusing into a room. The present invention includes a cabinet disposed over an oven range, a cooking room having a predetermined cavity within the cabinet for cooking using an electromagnetic wave generated from a magnetron, a hood unit installed within the cabinet to discharge polluted air produced from the oven range on cooking, and an air curtain generating unit installed at a bottom side of the cabinet to prevent the polluted air from diffusing into a room.

Abstract: The present invention relates to an over-the-range. The over-the-range including: a cavity having an electronic equipment chamber at one side, and within which cooking is performed; a door for opening and closing a cooking chamber within the cavity; a front grill part disposed at the upper side of the cavity and the upper side of the door, for air circulation; and a guide grill part combined to the front grill part such that the guide grill part can be transferred in the front and rear directions in a drawer type to suck and exhaust polluted air at a periphery of the cavity.

Abstract: Disclosed herein is a discharge valve for a compressor. The discharge valve comprises a valve plate for opening or closing a discharge port, a valve spring positioned downstream from the valve plate and adapted to provide elasticity to the valve plate, and a retainer positioned downstream from the valve spring and adapted to limit a maximum displacement of both the valve plate and the valve spring. The valve spring has a fluid-passage hole for the passage of fluid discharged from the discharge port. With such a configuration, the discharge valve can not only reduce flow loss and overshooting loss of the fluid, but also minimize backflow of the discharged fluid, resulting in an improvement in performance of the compressor.
