An exhaust air duct as a silencer mechanism is provided on the upper blower cover and is disposed between a blower receiving chamber and a cord receiving chamber. The exhaust air duct comprising an outer peripheral wall portion and a side wall portion. The outer peripheral wall portion has a partitioning rib and a curved guiding rib. The exhaust air duct forms a U-shaped exhaust air flow passage. An expansion chamber is disposed air flow passage. An expansion chamber is disposed at a down stream of the exhaust air duct. The exhaust air from an intake port of the exhaust air duct flows the U-shaped flow passage and is led to the expansion chamber. The suctioned air is expanded in the blower receiving chamber. The exhaust air is compressed in the exhaust air duct and is expanded again in the expansion chamber.

摘要： At an interior portion of a suction nozzle body, an impeller and a brush member are installed. The impeller is rotated in response to an air flow produced by a suction force and a brush or a blade member is mounted in a spiral shape along the whole impeller or a part of the impeller and contacts a surface to be subjected to cleaning. The rotary brush rotates integrally with the impeller on the same shaft and no partition wall is provided between the impeller and the rotary brush. A suction nozzle body having a small size, and which is of light weight and provides for silent operation, and a vacuum cleaner using the same, can be provided.

摘要： An electric vacuum cleaner having a body, suction generating means and a dust collection space in said body, and a rotatable hose inlet for receiving a suction hose and connecting the hose to the dust collection space. The suction hose has at one end a coupling engageable with said hose inlet. An electrical power supply cord socket is arranged to receive a plug of a power supply cord for a powered accessory of the vacuum cleaner. To avoid twisting of the cord around the hose, the cord socket is located on the hose coupling.

摘要： A vacuum cleaner with panel portion structure which includes an improved panel main body and a blower facility valve body. The panel main body has an exhaust air port and an opening for a blower facility. The blower facility valve body is provided at a lower side of the panel main body and is rotatably supported so as to normally shut the blower facility opening. A first exhaust air passage is formed between the intermediate exhaust air port to the main body exhaust air port. A second exhaust air passage is formed between the intermediate exhaust air port to the blower facility opening. The first exhaust air passage and the second exhaust air passage are changed over by the blower facility valve body. The improved blower facility structure permits the development of a series of vacuum cleaners with and without a blower facility.
