The flow path dividing means is provided, and the discharge pipe 14 extends into the secondary filter device chamber 6.

The dedicated dry flow passage 31 is preferably passed through the bottom of the recovery chamber (4).

The flow path dividing means is connected to the flow path switching plate 42 rotatably coupled to the shaft 41 to a predetermined portion of the inner tube 10, and is slidably coupled to a predetermined portion of the upper surface of the main body (B) flow path switching The flow path switching plate 43 which rotates and opens the plate 42, the elastic member 44 which elastically supports the flow path switching plate 42, and the flow force of the flow path switching knob 43 It consists of a power transmission means for transmitting to (42).

Preferably, the elastic member 44 uses a tension spring that is fixed at one end thereof to a fixing part 10a formed in the connection pipe 10 and the other end thereof to an inner surface of the flow path switching plate 42. .

The power transmission means is supported by the guide rollers 45 and 46 rotatably installed on both sides of the connection pipe 10, and the guide rollers 45 and 46, and one end thereof is a flow path switching plate 42.

An elastic body 51 such as rubber is fixed to the rear portion of the lower surface.

An O-ring 52 is fixed to the inlet of the dedicated wet flow path 32 to regulate the rotational operation of the flow path switching plate 42.

In the drawings, reference numeral 53 is a locking jaw, 54 is a wheel, and 55 is a reel code.

Referring to the effect of the wet and dry oil separator of the wet-dry vacuum cleaner according to the present invention configured as described above are as follows.

4 shows a case where the wet-type vacuum cleaner according to the present invention is used as the wet solution, and in this case, the locking protrusion 49 of the flow path switching knob 43 is connected to the locking groove 48 of the connecting pipe 10. It exits and is moved to the left in the figure by the elastic force of the elastic member 44, the flow path switching plate 42 is blocking the dedicated dry flow path (31).

In this state, when the motor 22 of the main body B is operated, a vacuum pressure is generated and the pump 16 is operated so that the washing liquid of the washing liquid tank 9 passes through the hoses 17 and 18 and the cleaning head ( Supplied by A).

Therefore, the cleaning head (A) is to clean the floor by using a normal liquid by the normal action, and the contaminants including the contaminated washing solution generated at this time along with the suction air extension pipe 13, the connection hose 12, And it is guided to the dedicated wet flow path 32 through the connector (10).

In this way, the contaminants sucked into the recovery chamber 4 of the main body B through the dedicated wet flow path 32 are deflected plates 11 formed at the end of the connecting pipe 10 downwardly, and the recovery tank 8 is enlarged. Due to the difference in the density of the air, the contaminants in the solid phase and the liquid contaminant liquids are separated by the gravity difference, which is accumulated at the bottom of the recovery tank 8. The remaining suction air passes through the discharge pipe 14 to the secondary filter. It is discharged to the mounting chamber (6).

At this time, the suction air passing through the dedicated wet flow path 32 is discharged directly to the secondary filter mounting chamber 6 without passing through the paper filter 15.

The air discharged to the secondary filter mounting chamber 6 passes through the secondary filter 20 and is discharged to the outside of the main body B via the motor 22.

At the same time, the flow path switching plate 42 is in contact with the O-ring 52 of the connection pipe 10 to block the dedicated wet flow path 32.

Therefore, the contaminants and suction air sucked in the cleaning head A are discharged directly to the paper filter 15 through the dedicated dry flow passage 31 of the connection pipe 10, and the contaminants are filtered by the paper filter 15. The suction air is secondarily purified by the secondary filter 20 of the secondary filter mounting chamber 6 and then discharged to the outside of the main body B through the motor 22.

In the wet state in this state, when the rear end portion of the flow path switching knob 43 is lightly pressed downward, the elastic body 51 is elastically pressed so that the flow path switching knob 43 is rearward by the hinge protrusion 50. The lifting part is lifted so that the locking protrusion 49 is released from the locking groove 48 of the connector 10.
