摘要： The vacuum cleaner has a hollow first fixing member formed together with a body, and a second fixing member assembled with the first fixing member. The first and the second fixing members are formed with a first and a second ribs respectively. The first and the second ribs form a circular-shaped supporting rib part when the first and the second fixing members are assembled with each other. A rotational shaft of a wheel is inserted into the supporting rib part to be assembled therewith. Thus a port for fixing the wheel need not be formed on the body, and the air drawn into the body is not discharged through such a port. Further, since the rotational shaft does not protrude into the body, it is easier to install components in the body and to disassemble the wheel from the body.

摘要翻译： 真空吸尘器具有与主体一起形成的中空的第一固定构件和与第一固定构件组装的第二固定构件。 第一和第二固定构件分别形成有第一和第二肋。 当第一和第二固定构件彼此组装时，第一和第二肋形成圆形支撑肋部。 轮的旋转轴插入到与其组装的支撑肋部分中。 因此，用于固定车轮的端口不需要形成在主体上，并且被吸入体内的空气不会通过这种端口排出。 此外，由于旋转轴不突出到体内，因此容易将部件安装在主体中并将车轮从车身拆卸下来。

摘要： In a vacuum cleaner a suction motor is installed in a front casing. The front casing has a first main body with a first suction opening connected to the suction motor. An opposite side face of the first main body is opened. A lower chamber communicates with the first main body by a penetrating hole. An upper chamber is installed on an upper part of the first main body. The lower chamber and the upper chamber communicate with each other by a rear casing which covers the front casing. An air guider is installed inside the front casing. The air guider has a second opened side face, an opposite second closed side face closed with a closing plate, and a top penetrating hole formed through a top surface of the second main body. The closing plate closes the opened side face of the first main body. Thus, air sucked into the suction motor is exhausted to an inside of the air guider. The air is guided to an outside of the air guider via the top penetrating hole, and downwardly guided along the outer surface of the cylindrical body of the air guider, and then flows into the lower chamber through the penetrating hole. The air flows into the upper chamber through the air flow path formed by the rear casing, and is exhausted to the outside of vacuum cleaner through the filter receiving part.

摘要翻译： 在真空吸尘器中，抽吸马达安装在前壳体中。 前壳体具有第一主体，其具有连接到抽吸马达的第一吸入口。 打开第一主体的相对侧面。 下室通过穿透孔与第一主体连通。 上部室安装在第一主体的上部。 下腔室和上腔室通过覆盖前壳体的后壳体相互连通。 空气导向器安装在前壳体内。 空气导向器具有第二开放侧面，与封闭板封闭的相对的第二闭合侧面，以及通过第二主体的顶面形成的顶部贯通孔。 封闭板封闭第一主体的开放侧面。 因此，吸入吸引马达的空气被排出到空气引导件的内部。 空气通过顶部通孔被引导到空气导向器的外部，并且沿空气导向件的圆筒体的外表面向下引导，然后通过穿透孔流入下室。 空气通过由后壳形成的空气流路流入上室，并通过过滤器接收部分排出到真空吸尘器的外部。
