Description

[Detailed description of the invention] This invention relates to a vacuum cleaner, and its purpose is to make it easier to install a power outlet attached to the wall of the vacuum cleaner and to make it difficult to remove, and to prevent air leakage from the attachment part. .

Conventionally, when fixing a power outlet to a wall surface outside a vacuum cleaner, a hook-shaped claw 102 is integrally formed on the power outlet 101 as shown in FIG. 4, and the elasticity of the claw 102 is used to force the power outlet into the wall. As shown in FIG. 5, an inclined surface 203 is provided at the end of the cord 202 side of the power outlet 201, and a rib 204 parallel to the axis of the power outlet 201 is provided from the vacuum cleaner body. There was one in which the rib 204 was deformed by forcing it in.

In the former case, it is necessary to provide a slight gap between the power outlet 101 and the wall surface of the main body in order to allow the hook-shaped claw 102 to pass through, and air leakage occurs from this gap, causing a decrease in suction performance. It had become.

In the latter case, in order to deform the rib 204 relatively easily, it is necessary to make the slope 203 long, which increases the size and the price.
If pulled too hard, the ribs 204 would deform outward and the power outlet 201 would sometimes come off.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a main body of a vacuum cleaner equipped with an electric blower and a dust collector (not shown), and is movable on wheels 2.

Reference numeral 3 denotes a hose, one end of which is connected to the main body 1 and the other end connected to an extension pipe 5 via a suction pipe 4.

An electric floor suction device 6 is connected to the tip of the extension pipe 5.

The power for the electric floor suction tool 6 is taken from the power outlet 7 provided on the main body 1, but first the plug 9 of the power cord 8 is
Connect it to the plug receiving part 10 of the hose 3.

A conducting wire is arranged in a spiral shape in the hose 3, and one end is connected to the plug receiving part 10 and the other end is connected to the plug 11, so that by connecting the plug 11 to the power outlet 7, the above-mentioned floor suction tool can be used. 6 can be energized.

A power outlet 7 is attached to the front wall surface 12 of the vacuum cleaner body 1.

The mounting configuration will be explained below.

Reference numeral 12a denotes a mounting opening formed in the wall surface 12, the opening edge of which is concave inward.

Reference numeral 15 denotes a pair of ribs protruding from the main body 1 facing the mounting port 12a, and are arranged in a V-shape such that the distance on the mounting port 12a side is wide.

On the other hand, the power outlet 7 has a sloped part 18 formed on its outer surface that narrows in width toward the rear so as to match the rib 15, and the rear end of the sloped part 18 is shaped like a step and is locked. Section 19 is set.

13 is a lead wire led out from the rear of the power outlet 7.

When installing, pass the lead wire 13 led out to the rear of the power outlet 7 from the outside to the inside through the installation opening 12a of the wall 12, and then insert the power outlet 7 into the installation opening 12.
a, but when it is inserted a little further than the position shown by the broken line in FIG.
6, and when further inserted, the rib 15 is deformed as shown by the broken line, and the rear end 17 of this rib 15 and the inclined part 1
The power outlet 7 is fixed when the locking portion 19 located at the terminal end of the power outlet 8 comes into contact with the locking portion 19 .

Since the rib 15 is inclined in a V-shape along the insertion direction of the power outlet 7, the amount of deformation gradually increases as the power outlet 7 is inserted. No force is applied and the ribs 15 are not adversely affected.

Moreover, once set, even if a force is applied to pull the power outlet 7 outward, a force acts on the rib 15 to cause it to fall inward, and it can effectively serve to prevent it from being pulled out.

In addition, air tightness can be done in a part unrelated to prevention of leakage, so it is possible to connect the power outlet 7 to the mounting hole 12a of the wall surface 12 to some extent.
Air leakage can be eliminated by pressing it into place.

As described above, according to the present invention, the power outlet can be easily fixed by simply providing an inverted V-shaped rib along the insertion direction of the power outlet and having a shape that fits into the rib.
It has the effect of reliably preventing deboning and also reliably tightening the air, and has great practical value.
