Abstract
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.
