Embodiment Construction

[0023] Below, refer to Figure 1 to Figure 7 An embodiment of the present invention will be described in detail.

[0024] Such as figure 1 As shown, the floor mobile vacuum cleaner using the present invention includes a vacuum cleaner main body 1, a hose 2, a connecting pipe 3, a floor suction 4, and the like.

[0025] In the vacuum cleaner main body 1, a motor chamber 6 and a dust collection chamber 9 using a paper bag 7 and a dust filter 8 are housed. The electric blower 5 for suction is housed in the motor chamber 6 .

[0026] An exhaust port 11 is formed on the back side of the cleaner main body 1 , and the exhaust port 11 discharges a part of the exhaust gas from the electric blower 5 to the outside through the exhaust filter 10 .

[0027] Also, a part of the vacuum cleaner main body 1, the hose 2, the connecting pipe 3, and the floor suction device 4 are constructed in such a way that the flow path is a double structure, and is divided into a suction flow path A and an...

Abstract

This invention is to achieve a light-weighted and slim-sized arrangement of the pipe through which an air suction flow passage and the air discharge flow passage passes in an electric vacuum cleaner of exhaust circumfluently flowing type. A pipe 3 comprises an inner cylindrical portion 3a to form an air suction flow passage A of substantially circular cross section, and an outer cylindrical portion 3b to form an air discharge flow passage B in which a part thereof is integrated formed with the inner cylindrical portion 3a and covers the inner cylindrical portion 3a. The air discharge flow passage B of the pipe 3 is of substantially crescent cross section, and the outer cylindrical portion 3b of the pipe 3 is of substantially circular cross section.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, in particular to an exhaust return (circulation) type electric vacuum cleaner, in which the exhaust gas of an electric blower installed in the main body of the vacuum cleaner flows back into the ground inhaler etc. through a hose and a connecting pipe. Background technique [0002] In general floor mobile vacuum cleaners, all the exhaust gas from the electric blower installed in the main body of the vacuum cleaner is exhausted to the outside from the exhaust port provided on the back side of the main body or the like. [0003] That is, the dust sucked together with the air by the floor suction device is sucked into the main body of the vacuum cleaner through the hose and the connecting pipe, and the air from which the dust is removed by the paper bag etc. cools the motor of the electric blower, and is discharged from the exhaust port to the vacuum cleaner. outside, but since all the exhaust f...
