TECHNICAL FIELD OF THE INVENTION
The dust separation unit is used to separate dust and air directly by inertia, centrifugal force, or physical force such as gravity using the centrifugal force generated by the rotation of the suction fan blades provided in vacuum cleaners and dust collectors. The present invention relates to a vacuum cleaner and a dust collector provided with a function of sucking dust at a certain distance from a suction nozzle in accordance with an exhaust circulation system by ensuring the safety of a rotating part by arranging it in front.
[0002]
[Prior art]
Some vacuum cleaners use a paper pack or a filter. However, as the dust is collected, the dust collecting ability is reduced due to clogging or the like, and it is necessary to replace the paper pack or clean the filter.
[0003]
There are cyclone type vacuum cleaners that use air to rotate and use centrifugal force, but the structure is complicated and rotation is limited due to air resistance and the like, and it is difficult to separate small dust.
[0004]
[Problems to be solved by the invention]
Dust is separated by strong centrifugal force by rotating the air with the force of the drive motor.
[0005]
Vacuum cleaners and dust collectors that are economical and do not require filter cleaning or replacement of paper packs, and do not reduce suction capacity due to clogging.
[0006]
Sanitary vacuum cleaners and dust collectors that do not allow air to pass through the dust of paper packs.
[0007]
The dust is separated by physical force using the centrifugal force generated by the rotation of the blades of the suction fan.
[0008]
A strong centrifugal barrier is formed around the air suction port to prevent dust from approaching.
[0009]
The centrifugal force generating plate and centrifugal force barrier forming plate have a simple and lightweight structure to reduce the motor load, thereby saving space.
[0010]
Even with the centrifugal force caused by the rotation of the blade of the suction fan itself, the dust is separated inside the blade and does not go out.
[0011]
Separating the rotating part from the dust container ensures safety.
[0012]
Vacuum cleaner compatible with exhaust circulation system.
[0013]
It sucks dust away from the suction nozzle to some extent, and sucks hidden dust such as gaps where the nozzle cannot enter.
[0014]
The nozzle sucks dust without directly touching the furniture or ceiling.
[0015]
[Means for Solving the Problems]
In order to secure the safety of the rotating part, the dust separating part is arranged separately in front of the dust container, and the rotating part is separated from the dust container.
[0016]
The blade of the suction fan is provided in the dust separation part facing the upper surface.
[0017]
A dust and air introduction path is provided around the blade of the suction fan in a spiral manner from the lower surface to the upper surface of the blade.
[0018]
The dust and air introduction path has a large dust drop port for dropping by inertia and gravity on the dust container side, and a dust and air inlet port for introducing the remaining dust and air to the upper surface side of the blade.
[0019]
A small dust drop port is provided on the dust container side on the upper surface side of the suction fan blades.
[0020]
Dust and air are separated using the function of generating centrifugal force by the rotation of the blades of the suction fan.
[0021]
A centrifugal barrier forming plate, which is a rotating plate made of a plate having air permeability, is provided near the circumference of the blade of the suction fan so as to block air toward the air outlet.
[0022]
The centrifugal barrier formed by the centrifugal barrier prevents the dust from approaching the air outlet, and separates the dust and air by sucking and discharging the air from the air suction port against the centrifugal force.
[0023]
The dust introduced on the upper surface side of the suction fan is prevented from approaching the suction port 3 by the centrifugal force and the centrifugal force barrier of the centrifugal barrier forming plate.
[0024]
On the other hand, air separates dust and air by sucking and discharging through a centrifugal barrier forming plate which is a plate having air permeability against centrifugal force.
[0025]
The dust is separated even by the centrifugal force caused by the rotation of the suction fan blade itself, and a dust return gap is created on the peripheral side wall of the blade where the dust collects, so that this dust is not returned to the dust separation part and is not taken out. Also serves as a gap.
[0026]
The centrifugal force generating plate and the centrifugal barrier generating plate have a simple structure and are made of a lightweight material so that they can be directly driven by a motor.
[0027]
An exhaust nozzle is circulated around the suction nozzle to form a curtain of exhaust air in order to suck dust away from the suction nozzle to some extent, thereby blocking suction from the lateral direction and concentrating the suction force in the forward direction.
[0028]

On the side of the dust container 8 on the upper surface side of the blade 1 of the suction fan, a small dust drop port 11 for dropping dust by centrifugal force and gravity is provided.
[0032]
The blade 1 of the suction fan provided in the dust separating section has a function of rotating surrounding air by rotating to generate a centrifugal force, and separates dust by using this function.
[0033]
The centrifugal barrier forming plate 2 is a rotary plate made of a plate having air permeability and is provided around the suction fan blades 1 so as to block air toward the air outlet 3 and rotates together with the suction fan blades 1. A strong centrifugal barrier is formed in the adjacent air to prevent dust from approaching the outlet 3.
[0034]
On the other hand, the air is sucked by the suction fan through the centrifugal barrier forming plate 2 which is a plate having air permeability against the centrifugal force, and is discharged from the discharge port 9 of the cleaner to separate dust and air.
[0035]
Dust remaining slightly even by centrifugal force caused by the rotation of the suction fan itself is separated inside, and a dust return gap 4 is provided on the peripheral side wall of the blade where the dust collects, so that the dust is returned to the dust separation portion and does not go outside.
[0036]
An exhaust nozzle is provided around the outside of the suction nozzle, and an air curtain of exhaust air is formed outside the suction nozzle to block the suction of the suction ports 31 and 41 from the lateral direction and concentrate the suction force in the forward direction.
[0037]
The process of dust separation will be described with reference to the drawings.
Both dust and air are sucked from the suction nozzle of the vacuum cleaner and guided to the dust and air introduction path 6.
[0038]
Dust larger than the large dust drop port 10 in the dust and air introduction path 6 is dropped into the dust container 8 by inertia force and gravity.
[0039]
The remaining dust and air are both introduced into the upper surface of the blade 1 of the suction fan from the small dust and air inlet 7 and the dust is centrifugal due to the rotation of the blade 1 and the centrifugal barrier formed by the centrifugal barrier forming plate 2 to remove the dust. From the outlet 3 of the container, and falls into the dust container 8 from the small dust outlet 11 by centrifugal force and gravity.
[0040]
On the other hand, the air is sucked toward the air outlet 3 against the centrifugal force and is discharged from the outlet 9 of the vacuum cleaner, whereby the dust and the air are separated.
[0041]
Although the dust is separated inside the blade by the centrifugal force caused by the rotation of the blade 1 of the suction fan, the dust is returned to the dust separating portion through the dust return gap 4 provided on the circumferential side wall of the suction fan where the dust collects.
[0042]
The air curtain of the exhaust nozzle that surrounds the outside of the suction nozzle blocks the suction from the suction ports 31 and 41 from the lateral direction, and the suction force is concentrated in the forward direction, so that dust that is some distance from the suction nozzle can be sucked. .
[0043]
The centrifugal force generating plate will be described in detail.
The blade 1 of the suction fan has a function of rotating the surrounding air by rotation to generate centrifugal force and can be used for dust separation. However, the centrifugal force can be increased by adding a rotating plate near the circumference.
[0044]
The effect of the centrifugal force can be enhanced by providing irregularities or short blades on the surface of the centrifugal force generating plate, but the load on the motor increases.
[0045]
The centrifugal barrier forming plate 2 will be described in detail.
The centrifugal barrier forming plate 2 is provided with a number of slits or small holes, or is made of a light-permeable material such as a mesh or a nonwoven fabric.
[0046]
The centrifugal barrier forming plate 2 is provided so as to block the air flowing toward the air outlet 3, and is driven directly by a motor together with the blades 1 of the suction fan to rotate to form a barrier due to strong centrifugal force to the adjacent air to approach the dust. On the other hand, air is sucked by the suction fan against the centrifugal force and discharged from the outlet 9 of the cleaner to separate dust and air.
[0047]
The centrifugal barrier forming plate 2 needs to have sufficient air permeability and area to allow all of the air going to the air outlet 3 to pass through.
[0048]
The centrifugal barrier forming plate 2 forms a barrier by centrifugal force and also generates centrifugal force. The centrifugal force generating plate can also function as a centrifugal force generating plate. In this case, the centrifugal force generating plate can be omitted.
[0049]
The suction nozzle will be described in detail.
By circulating an exhaust nozzle around the outside of the suction nozzle and circulating an air curtain of the exhaust air, the suction of the intake ports 31 and 41 from the lateral direction is blocked, and the suction force is concentrated in the forward direction. .
[0050]
If the exhaust nozzle is angled outward as shown in FIG. 3, a wide range can be sucked, but the suction force is weakened. If the exhaust nozzle is angled inward as shown in FIG. 4, the suction range is narrowed, but the suction force is increased.
[0051]
The shape of the suction ports 31, 41 can be elongated.
[0052]
The rectifying plates 33 and 43 are for regulating the flow of the exhaust air and giving resistance to the inside, thereby increasing the flow outside and suppressing the expansion of the air curtain to the outside.
[0053]
The amount of exhaust air and the amount of suction air are equal, and all exhaust air is sucked and dust is not blown out by the exhaust air.
