Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a domestic or commercial vacuum cleaner for collecting and cleaning dust on indoor floor surfaces and the like.

[0002]

2. Description of the Related Art In a conventional vacuum cleaner, since a suction force of air is generated inside a suction inlet connected to a cleaner body to suck and collect dust together with the air, for example, a carpet. There was a problem that dust that could not be sucked out by the suction force, such as dust that entered between the piles, could not be collected and cleaned. Also, in the conventional vacuum cleaner, the dust sucked into the cleaner body is collected in the dust collecting part and the air is allowed to escape from the exhaust port as it is, so the air actually passed through the filter of the dust collecting part. In many cases, fine dust is still contained in the dust, and the fine dust is secondarily scattered and released into the atmosphere.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. For example, it is possible to efficiently and easily collect and clean even dust particles that have entered between the piles of a carpet. At the same time, it is an object of the present invention to provide a vacuum cleaner that does not secondarily release fine dust into the atmosphere.

[0004]

A vacuum cleaner according to the present invention that achieves the above object has a cleaner body having a dust collecting section and a fan between an inlet and an outlet, and the cleaner. A suction passage connected to the main body via a duct pipe, the duct pipe being connected to a suction passage of the cleaner main body and a suction passage connected to a blow outlet. The suction end of the suction passage and the discharge end of the discharge passage of the duct pipe are respectively faced to the suction port of the suction port device, and swirled into the suction port by the air blowing flow and the suction flow. It is characterized by generating a vortex flow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a cleaner body, 2 is a suction port tool, and 3 is a duct pipe for connecting the cleaner body 1 and the suction port tool 2, respectively.

The cleaner body 1 is provided with a dust collecting portion 11, a filter 12 and a fan 13 inside, a suction port portion 14 is arranged on the front side of the dust collecting portion 11, and a rear side of the fan 13 The outlets 15 are arranged respectively. That is, fan 13
Dust collected by the suction port device 2 is taken into the cleaner body 1 from the suction port portion 14 via the duct pipe 3 and is collected in the dust collection portion 11 by the suction force generated by the rotation of the filter 12. After filtering the fine dust with, the exhaust gas is sent again from the blowout port portion 15 to the suction port device 2 via the duct pipe 3.

The duct tube 3 is a suction port of the cleaner body 1.
The suction passage 31 is connected to 14 and the blowout passage 32 is connected to the blowout port 15 of the cleaner body 1. The suction passage 31 is connected to the suction port device 2 in a communicating manner. Suction end 31 'of passage 31 and outlet end of outlet passage 32
The 32 'faces the suction port 21 of the suction port device 2.

The suction port device 2 is formed in a required size, for example, in a substantially T-shape including the connecting portion 22 with the duct pipe 3, and the suction port 21 is formed inside.
The suction end 31 ′ of the suction passage 31 of the duct pipe 3 and the blow-out end 32 ′ of the blow-out passage 32 are made to face 21 and a swirling vortex flow is generated inside the suction port 21 by the blowout flow and the suction flow of air. I will let you.

That is, the suction port 21 of the suction port device 2 is formed in a substantially spindle shape, and the blowing end 32 'of the blowing passage 32 of the duct pipe 3 is faced in the lower tangential direction at the center position thereof.
With the suction end 31 'of the suction passage 31 facing the upper position,
A swirling vortex flow is generated inside the suction port 21 by the air blowing flow from the blowing end 32 'and the air sucking flow from the suction end 31'.

At this time, as shown in the illustrated embodiment, the passage 24 leading to the outlet end 32 'of the outlet passage 32 and its outlet 23.
Is formed along the suction port 21 formed in the substantially spindle shape, it becomes possible to generate a more effective swirling vortex inside the suction port 21, and the end port 24 ′ of the passage 24. By communicating with the suction port 21, the dust inside the suction port 21 can be effectively conveyed to the suction end 31 ′ of the suction passage 31. In this case, the suction port member 2 is not formed into a substantially T shape as in the illustrated embodiment, but the duct pipe 3 is used.
For example, it may be formed in a substantially L-shape including the connecting portion 22 with.

When the fan 13 of the cleaner body 1 is rotated, an air suction force is generated in the suction port portion 14 of the cleaner body 1 and an air blowing force is simultaneously generated in the discharge port portion 15. As a result, the suction port device 2 is passed through the duct pipe 3.
Inside the suction port 21 of the air, the blowout flow of air from the blowout end 32 'of the blowout passage 32 and the suction end 3 of the suction passage 31
A swirling vortex is generated by the air suction flow entering from 1 '.

[0012] Then, the dust in the portion to be cleaned facing the suction port 21 of the suction port device 2 is fluidized by the action of the swirling vortex flow in the suction port device 21 and rolled up into the suction port 21 of the suction port device 2. Is sucked up in such a manner that it passes through the suction passage 31 of the duct pipe 3 and the dust collecting portion from the suction opening portion 14 of the cleaner body 1.
Captured within 11.

[0013]

Since the vacuum cleaner of the present invention has such a structure, the dust is fluidized by the action of the swirling vortex generated in the suction port of the suction port device, and the fluidized dust is sucked into the suction port device. It can be sucked up and collected by rolling it up from the mouth. Therefore, for example, dust and dirt trapped between the piles of the carpet can be efficiently and easily collected and cleaned.

Moreover, since the dust is fluidized by the action of the swirling vortex generated in the suction port of the suction port device and is sucked up and collected by being wound up from the suction port of the suction port device,
Unlike the conventional scraping and collecting with a brush or the like, it is possible to clean not only the floor surface in the room but also the lawn in the garden without damaging the grass.

Further, the exhaust gas that has passed through the filter in the cleaner body is guided from the outlet through the duct tube into the suction port of the suction port device, and is circulated and reused as a swirling vortex source generated in the suction port of the suction port device. Therefore, no special equipment is required as an energy source for generating a swirling vortex, energy can be saved during use, it can be manufactured at low cost, and fine dust like conventional products is generated. Next, it is possible to prevent the scattered emission into the atmosphere, and at the same time, reduce the exhaust noise.
