Description

[Detailed Description of the Invention] The present invention relates to an improvement of a vacuum cleaner for a centralized dust collection system, and is aimed at improving assembly efficiency.

Generally, this type of vacuum cleaner has an auxiliary electric blower installed in series with the main electric blower on the side of the vacuum cleaner body, and this auxiliary electric blower can be used in conjunction with the main electric blower as needed to collect dust piped inside the house. It was designed to cope with changes in the ventilation resistance of the pipeline.

The reason why the auxiliary electric blower is placed on the side of the vacuum cleaner body is to make the height of the vacuum cleaner body as low as possible.

That is, if the main and auxiliary electric blowers are arranged vertically in a series relationship, the height of the vacuum cleaner body increases accordingly, and the installation location is restricted.

However, when installing this auxiliary electric blower on the side of the main body, it is difficult to support and fix the auxiliary electric blower, especially on the rear side opposite to the main body, making it impossible to securely support and fix it and making assembly very difficult. There were drawbacks.

The present invention eliminates such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a vacuum cleaner body, which is supported by pipe-shaped legs 2, and a dust collection box 4 is attached below it via a buckle 3.
is removably connected.

Reference numeral 5 denotes a dust collecting device installed in the dust collecting box 4, which includes a cylindrical main filter 6, a filter 7 on the same side, a dust removing body 8, a handle body 9 for rotating the dust removing body 8, and a handle body axis. 10
It is attached to the dust collection box 4 via a packing 12 provided on the outer periphery of the device board 11.

13 is a dust suction port, and 14 is a hose connected to a dust suction pipe (not shown) inside the house.

Reference numeral 15 denotes a main electric blower provided in the vacuum cleaner main body 1, and is fixed to the main body wall 1a via a support frame 16.

Reference numeral 17 denotes an auxiliary electric blower disposed in series with the main electric blower 15 on a part of the side surface of the vacuum cleaner body 1, the front part of which is placed in a bottomless cylindrical support tube 18 fixed to the cleaner body 1. They are fitted and held by a ring-shaped elastic support 19.

Reference numeral 20 designates a bottomed cylindrical cover tube that covers the rear part of the auxiliary electric blower 17, and is fitted onto the opening edge 18a of the support tube 18 and secured with screws (not shown).

In the above configuration, since the auxiliary electric blower 17 disposed on one side of the vacuum cleaner body 1 is very heavy, the elastic support 19
It is insufficient to hold the front part by the cover cylinder 20.
It also needs to be supported at the rear.

Therefore, in the present invention, a cylindrical support part 24 is provided at the bottom of the cover cylinder 20, into which the support body 23 attached to the rear end of the auxiliary electric blower 17 is fitted.
The rear end portion of the auxiliary electric blower 17 is supported by fitting into the auxiliary electric blower 17.

However, since the support portion 24 of the cover tube 20 is located at the bottom of the cover tube 20 and is difficult to see from the outside, the cover tube 20 is not attached to the opening edge 18 of the support tube 18.
When fitting the support part 24 to the support body 23, it becomes very difficult.

Therefore, in the present invention, an exhaust port 26 for connecting the exhaust pipe 25 is provided on a part of the outer circumference of the cover cylinder 20, and the support cylinder 1
8, the supporting part 24 inside the cover cylinder 20 can be seen from the exhaust port 26 while the supporting part 24 of the auxiliary electric blower 17 is being fitted to the supporting part 23 of the auxiliary electric blower 17.

In addition, in this embodiment, the support body 23 is further provided with a protrusion 23a.
In addition, a recess 24 a is provided in the support portion 24 of the cover tube 20 in correspondence with the projection 23 a, and the auxiliary electric blower 17 is positioned by fitting the recess 24 a into the projection 23 a. It also prevents rotation.

Therefore, in this embodiment, the support body 23 is made of an elastic material such as rubber and fitted onto the auxiliary electric blower 17, so that the auxiliary electric blower 17 and the support body 23 are integrated.

As described above, according to the present invention, since the rear part of the auxiliary electric blower is supported by the support part provided at the bottom of the cover tube, reliable support can be achieved, and the support part of the cover tube is provided on the outer peripheral surface of the cover tube. Since it is visible from the exhaust port, the support part and the support body can be fitted together while looking through the exhaust port, and assembly can be performed easily and quickly.

Moreover, since the aperture serving as the viewing window is constructed using an exhaust port, there is an advantage that the construction can be simple, such as no need to add any special construction.
