    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.

    摘要翻译： 一种具有面板部分结构的真空吸尘器，包括改进的面板主体和鼓风机设备阀体。 面板主体具有排气口和用于鼓风机设备的开口。 鼓风机设置阀体设置在面板主体的下侧，并被可旋转地支撑，以便正常地关闭鼓风机设备开口。 第一排气通道形成在主体排气口的中间排气口之间。 第二排气通道形成在吹风机设置开口的中间排气口之间。 第一排气通道和第二排气通道被鼓风机设备阀体转过。 改进的鼓风机设备结构允许开发具有和不具有鼓风机设备的一系列真空吸尘器。

    摘要： A blower cover is provided so as to surround an electric driven blower. The blower cover comprises an upper blower cover and a lower blower cover. 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.
