Description

[Detailed description of the invention] Industrial applications The present invention relates to a vacuum cleaner for general household use.

Prior art In the conventional example shown in FIGS. 3 and 4, the vacuum cleaner body 1 is composed of a vacuum cleaner body cloth 1a and a left vacuum cleaner body 1b.
It has a built-in electric blower 2.

On the left side 1b of the cleaner body, an exhaust port 3 is formed laterally by a grid 4. Further, the vacuum cleaner #1 is provided with a handle 5 at the upper part, a telescopic extension pipe 6 is connected to the lower part and fixed by a tightening ring 7, and a floor nozzle 8 is connected to the tip of the extension pipe 6.

Problems to be Solved by the Invention In the conventional vacuum cleaner as described above, the electric blower 2
The exhaust air 9 exits from the exhaust port 3 provided immediately next to the electric blower I12, so the high frequency sound caused by the exhaust is particularly high and the noise is high.

The present invention solves the above problem, and the l! The purpose is to provide a vacuum cleaner with low noise.

Means for Solving the Problems In order to solve the above-mentioned problems, the vacuum cleaner of the present invention is designed such that the vertical center of the vacuum cleaner body and the center of the electric blower built into the vacuum cleaner body are shifted, and the exhaust port is opened. A rib is provided on the opposite side to the direction in which the electric blower is shifted, and a rib is formed from the cleaner body between the electric blower and the exhaust port.

Effect In the above configuration, the exhaust air from the electric blower is not directly discharged from the exhaust port to the outside by the rib provided between the electric blower and the exhaust port, but is exhausted in a detour manner through the rib, and moreover, it is exhausted for cleaning. Since the centers of the machine body and the electric blower are shifted and the exhaust port is provided on the opposite side to the direction in which the electric blower mR is shifted, the exhaust passage can be made long and noise can be reduced.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic sectional view showing a vacuum cleaner according to an embodiment of the present invention, and FIG. 2 is a perspective view of the same vacuum cleaner. In FIG. 1 and FIG. 2, the vacuum cleaner main body 11 is
11a and a lower part 11b of the vacuum cleaner main body, and has an electric blower l112 built inside.

A dust collection box lid 13 is detachably attached to the lower part of the upper part Ha of the vacuum cleaner body with a buckle 14. In addition, a floor nozzle 15 is attached to one end of the vacuum cleaner body 11, and a handle 16 is attached to the other end.
It is disposed via a handle 17 attached between the The electric blower 1112 built into the vacuum cleaner main body 11 is provided with its center offset from the center of the vacuum cleaner main body 11, and the exhaust port 18 is located at the bottom of the vacuum cleaner main body 1) 1111b on the opposite side to the direction in which the electric blower 112 is shifted. and this exhaust port 1
8 and electric feeder Ji [11, lower part of the vacuum cleaner body 11'!
A rib 19 is integrally formed from +11b to the height of the upper end 18a of the exhaust port 18. An exhaust port gasket 20 made of a sound deadening material such as urethane foam is attached to the inner surface of the exhaust port 18.

In the vacuum cleaner with the above structure, the exhaust air 21 coming out of the electric blower 12 collides with the rib 19 formed on the lower side 11b of the vacuum cleaner body, and is exhausted to the outside from the exhaust port 18 in a detour manner. The exhaust passage can be made longer, significantly reducing noise.

In the above embodiment, the rib 19 is integrally formed on the lower side 11b of the cleaner body, but the rib 19 is formed on both the upper side 11a of the cleaner body and the lower side 11b of the cleaner body, Butt the vacuum cleaner body 11 almost in the center,
It may also have a shape with a part cut out.

Effects of the Invention As described above, in the vacuum cleaner of the present invention, the built-in electric blower is shifted from the center of the vacuum cleaner body to the side opposite to the exhaust port, and a rib is formed between the electric blower and the exhaust port. As a result, the exhaust passage can be made longer, and since the exhaust gas once hits the ribs and does not directly exit outside, the noise can be significantly reduced, which is a special effect.

Claims (1)

[Claims] 1. The vertical center of the vacuum cleaner body and the center of the electric blower built into the vacuum cleaner body are offset, and the exhaust port is provided on the opposite side to the direction in which the electric blower is shifted, and the electric blower and the exhaust port are connected. In between, the vacuum cleaner formed a lip from the vacuum cleaner body.
