Description

[Detailed Description of the Invention] The present invention relates to an improvement of a dust collector.

The dust collector generally consists of a motor installed on a base, a fan driven by the motor, a fan casing surrounding the fan, and a wind tunnel connected to the fan casing. When in use, a dust bag is attached to the dust outlet provided at the tip of the wind tunnel, and by driving a fan, the dust sucked into the dust collector is sent into the dust bag and collected. In conventional dust collectors, by removing the dust bag from the dust collector body, the dust collected in the dust bag is thrown into a trash can.

The present invention is a further improvement of the conventional dust collector with the above-mentioned configuration, and its purpose is to separate the dust to be collected by the dust collector according to its size and type. The dust collector itself can be used for sorting, or even using a cleaning blower (the ``cleaning blower'' in this invention is used to remove dust that accumulates in hidden places that are out of the reach of the public eye, dust that accumulates in corners, etc.). The purpose of the present invention is to provide a dust collector that can function as a device that has the function of blowing away dust that accumulates in areas that are difficult to remove using the method described above, and then collecting it again. be.

In order to achieve the above object, the present invention includes a motor disposed on a base, a fan driven by the motor, a fan casing surrounding the fan, and a wind tunnel connected to the fan casing. This dust collector is characterized in that the wind tunnel is branched into a plurality of paths, and each branch path is selectively opened and closed by opening and closing operations of a fluid direction conversion damper.

The present invention will be explained below based on the drawings.

FIG. 1 is a side view showing an embodiment of a dust collector according to the present invention, and FIG. 2 is a front view of FIG. 1.

In FIGS. 1 and 2, reference numeral 1 indicates a base of the dust collector body, 2 indicates a motor disposed on the base 1, and a fan 3 is directly connected to the motor 2. 4 is a fan casing that surrounds the fan 3; 5a and 5b are bifurcated wind tunnels connected to the fan casing 4; fluid direction conversion dampers 6 are provided at the bifurcated branch portions of the wind tunnels 5a and 5b; There is. In the figure, 7 indicates a lever attached to the upper end of the support shaft of the damper 6, 8 indicates a dust suction port provided in the fan casing 4, and 9a and 9b indicate dust discharge ports provided in the wind tunnels 5a and 5b, respectively.

Figures 3 through 5 all show different usage examples of the dust collector shown in Figures 1 and 2 above, and Figure 3 shows an example of how it is used as a general dust collector.
FIG. 4 shows an example of use as a dust collector, which is unique to the present invention, and FIG. 5 shows an example of use as a cleaning blower, which is also unique to the present invention.

In FIG. 3, 10 is a hose connected to the dust inlet 8 of the fan casing 4, 11 is a dust bag connected to the dust outlet 9b via a hose band 12, and air 1 is supplied from the dust inlet 8.
The dust 14 sucked together with the dust bag 11 passes through the fan casing 4, flows through the wind tunnel 5b whose direction of flow is selected by the damper 6, and enters the dust bag 11.
Dust bag 1
1 is made of a material with good air permeability, such as cotton, so that only dust 14 is collected in the dust bag 11, and air 13 is discharged outside the dust bag 11.

In the usage example shown in FIG. 4, a hose 15 is connected to another dust outlet 9a in addition to the dust bag 11 shown in FIG. As a result, the dust 14 sucked in from the dust inlet 8 passes through the wind tunnel 5a and is discharged to the discharge system of the hose 15 (for example, a predetermined trash can).
According to this usage example, by switching the damper 6,
The collection location can be selected depending on the size and type of the dust 14.

In the usage example shown in FIG. 5, the nozzle 16 is connected to the tip of the hose 15 used, and the air 13 is
According to this usage example, dust that is difficult to remove using normal methods, such as dust that accumulates in hidden places where people cannot see or dust that accumulates in corners, etc. Even if the dust accumulates in a certain place, it can be blown to another place by the air 13 ejected from the tip of the nozzle 16, and then collected again.

In addition to the usage examples shown in FIGS. 3 to 5, the dust collector of the present invention has dust bags 11 and 1 at both the dust outlet ports 9a and 9b, for example.
1, or instead of the dust bags 11, 11, connect the hoses 15, 15 to the dust outlet ports 9a, 9b.
15 can also be connected and used.

As described above, the present invention is a further improvement of the conventional dust collector, and in addition to being used as a general dust collector, it can also be used to collect dust depending on its size and type. It is possible to obtain a practical dust collector that can be used for a variety of purposes, such as sorting and even allowing the dust collector itself to function as a cleaning blower.
