In such a cyclone vertical vacuum cleaner, intake air is generated by the rotation of the fan motor 102.
The intake air flowing into the outer cyclone 103a from the suction port 101a through the support column 104 and the hose 106 advances in a downward spiral to separate large dusts and the like and deposit them in the outer cyclone 103a. Thereafter, the intake air flows into the inner cyclone 103b from above the outer cyclone 103a through the hose 107, and while advancing in a downward spiral, fine dust and the like are separated and deposited in the dust container 109.

Then, the collected intake air is taken into the inner cyclone 1
03b, the hose 108, the pillar 105, the fan motor 102, and the exhaust port 110. As a result, dust is collected.

[0006]

However, since the cyclone vertical vacuum cleaner is moved and used, the cyclone device 103 and the fan motor 102 cannot be made large. Therefore, it is not possible to sufficiently separate fine dust and the like, and the dust and the like are exhausted from the exhaust port 110,
There was a problem of low dust collection performance.

An object of the present invention is to provide a cyclone type vertical vacuum cleaner capable of improving dust collecting performance.

The cyclone vertical vacuum cleaner includes a handle body 1 that a user grips and moves, a cleaner body 2, and a nozzle body 3 rotatably supported by the cleaner body 2.

The front surface of the cleaner body 2 can be opened and closed by a lid 2b. An inverted cone-shaped cyclone 21 is provided above the inside of the cleaner body 2, and a detachable dust collecting cassette 22 is disposed below the cyclone 21 in close contact with a packing 23. A fan motor chamber 20 in which the fan motor 4 is arranged is provided below the dust collecting cassette 22, and a suction chamber 20 in which an intake port 4b of the fan motor 4 is arranged by a packing 26.
a and the exhaust chamber 20 in which the exhaust port 4c of the fan motor 4 is arranged
It is divided into b and. An opening 20c is provided in the suction chamber 20a.
Is provided and is connected to the upper surface of the cyclone 21 by a connecting pipe 24.

The bottom surface 3a of the nozzle body 3 is provided with a suction port 3b which opens facing the floor surface. Rotating brush body 3
1 is arranged in a suction chamber 3c formed in the front part of the nozzle body 3, is connected to the motor shaft 4a of the fan motor 4 by a belt 32 and rotates, and scrapes the floor surface through the suction port 3b. ing. A connection pipe 34 is connected to the suction chamber 3c, and the connection pipe 34 is connected to the upper side surface of the cyclone 21 via a connection portion 6 by a connection hose 5.

The connecting portion 2 is connected to the exhaust port 4c of the fan motor 4.
One end of a flexible circulating hose 8 is attached via 5. A hollow recirculation nozzle 36 is connected to the other end of the recirculation hose 8 so as to spread and cover the front part of the suction chamber 3c downward, and a blowout port 36a at the tip of the recirculation nozzle 36 opens toward the front part of the suction port 3b. Is provided. By making the return hose 8 flexible, the nozzle body 3 can be rotated and the inclination angle of the cleaner body 2 can be changed.

In such a cyclone type vertical vacuum cleaner, the suction chamber 3c, the connection pipe 34, the connection hose 5 and the connection portion 6 form a first suction passage A1 for communicating the suction port 3b with the cyclone 21. ing. In addition, the connecting pipe 24,
The opening 20c and the suction chamber 20a form a second suction passage A2 that connects the cyclone 21 and the intake port 4b of the fan motor 4 to each other. Further, the connecting portion 25 and the return hose 8
The recirculation nozzle 36 forms a recirculation channel A3 that connects the exhaust port 4c of the fan motor 4 and the suction port 3b.

When the intake air is generated by the rotation of the fan motor 4, the intake air containing the dust sucked from the suction port 3b flows into the upper portion of the cyclone 21 through the first suction passage A1. Then, while advancing in a spiral shape downward, dust is separated and accumulated in the dust collection cassette 22, and reaches the fan motor 4 through the second suction passage A2. The exhaust gas that has passed through the fan motor 4 is blown out from the blowout port 36a to the front part of the suction port 3b through the ring flow path A3, blows up the dust on the floor and is sucked in from the suction port 3b.

Therefore, the fine dust that cannot be separated by the cyclone 21 is sucked through the suction port 3b without being discharged to the outside together with the exhaust gas, and the cyclone 21 is repeatedly used.
Therefore, the dust collection performance can be improved and the cyclone 21 can be made small and lightweight.
Further, by disposing the blowout port 36a of the reflux nozzle 36 in front of the suction port 3c, dust on the floor surface can be blown up and collected reliably.

Further, in the present embodiment, the bypass passage 9 that branches from the reflux nozzle 36 and communicates with the connection pipe 34 is provided on the upper surface of the nozzle body 3. 4A and 4B are cross-sectional views of the bypass passage 36 in the longitudinal direction and the width direction. The bypass passage 9 has a rectangular cross section, and a flow rate adjusting means 10 having a flat valve 91 for adjusting the flow rate in the bypass passage 9 is provided in the middle of the passage.

The valve 91 is integrated with an operation knob 92 provided above the bypass passage 9 via a support shaft 92a, and the passage of the bypass passage 9 can be blocked by horizontally rotating the operation knob 92. It is like this. Operation knob 9
A pin 94 that is biased by a compression spring 94 in a direction of pressing the outer wall of the bypass passage 9 is provided on the inner side of 2, and by fitting with a plurality of recessed grooves 9 a provided in the outer wall of the bypass passage 9. The operation knob 92 can be stopped at a desired rotation position.

Normally, the fan motor 4 is driven by the valve 91 in a state where the bypass 9 is closed, and cleaning is performed by maximizing the flow rate of the circulation passage A3. Valve 9 by operating knob 92
When 1 is opened, a part of the exhaust gas passing through the circulation channel A3 comes to flow into the first suction channel A1 via the bypass channel 9. As a result, when the air pressure of the exhaust air of the fan motor 4 blown out from the air outlet 36a is large, the air pressure can be adjusted to prevent the dust from scattering on the floor surface and improve the dust collection efficiency.
