Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a central cleaner with improved installation.

In conventional central cleaners, the main body, which includes an electric blower, filter, dust box, etc., is designed to be installed indoors, such as under stairs, in a closet, or in a storage room. However, unlike general cleaners, the main body of the central cleaner is considerably large, and therefore, there are often location limitations when it comes to actual installation.

The present invention eliminates these conventional drawbacks, and embodiments thereof will be described below with reference to the accompanying drawings.

First, in FIG. 1, dust-laden air from a hose 3 that is inserted into one of the plurality of hose inlets 1 provided on the walls of each room and has a suction device 2 at its tip is drawn by the suction force of an electric blower 4. The dust flows through the suction passage 5 and is then passed through the dust container 6. To further explain the details with reference to FIG. 2, the dust container 6 is installed outdoors A, its upper opening is closed with a lid 7, and a removable insertion pipe 8 is provided at the bottom of the peripheral wall. A suction passage 5 is connected thereto. Reference numeral 9 indicates a check valve, 10 indicates a filter attached to the lid 7, and 11 indicates a packing for air-tighting between the dust container 6 and the lid 7.

On the other hand, the electric blower 4 is housed in a box 12 and installed under the floor C in a room B. The top plate 13 of the box 12 constitutes a part of the floor surface D, and an intake port 14 is formed on one side and an exhaust port 15 is formed on the bottom surface. 16 is a partition plate having a vent 17 facing the intake port 14; 18 is a duct connecting this vent 17 and a vent 19 formed in the center of the lid 7; It is configured. 22 is a fitting for the suction passage 5; 23 is a top plate 13;
The handle is shaped like this.

In the above configuration, the dust-containing air that flows into the dust container 6 from the suction passage 5 is passed through the filter 10, and then only the air is sucked into the electric blower 4 through the duct 18 and flows out from the exhaust port 15 of the box 12. do. The dust filtered through the filter 10 accumulates in the dust container 6.

Next, when discarding the dust inside the dust container 6, use the lid 7.
Then, the insertion pipe 8 may be removed and the dust container 6 may be taken out from the installation location.

Further, the electric blower 4 can be taken out from under the floor C via the box 12. For example, the top plate 13 of the electric blower 4 can be removed from the box 12.
If they can be separated further, inspection and repair can be performed very easily.

In FIG. 2, a bellows-like gasket 11' is interposed between a cap-like lid 7' and a dust container 6', and an intake passage 5' is formed on the circumferential surface of the lid 7' between a filter 10'. In this example, the dust container 6' can be attached and detached very easily.

As described above, according to the present invention, the electric blower does not cause electrical failure due to external conditions such as rain.
In addition, since only the electric blower section is installed indoors, it can be reliably installed under the floor, making effective use of space in the house. Furthermore, since the dust container can be installed outdoors, its shape can be increased as needed, which provides excellent effects.
