Description

Floor intake {NOZZLE FOR FLOORS}

The present invention relates to a floor suction inlet having a rotating brush.

Conventionally, the vacuum cleaner is configured to discharge the exhaust from the electric blower built in the cleaning main body to the outside from the exhaust port formed on the back of the main body, but the user may feel unpleasant due to the smell of the exhaust or the exhaust from the electric blower In order to exhaust all of them, there is a drawback that the power of exhaust is strong and the air blows out dust on the floor or carpet and spreads away.In recent years, in consideration of this drawback, exhaust from the electric blower is used as a floor inlet. It is known to form a circulation path for reflux.

Such a vacuum cleaner is used to improve the exhaust efficiency by blowing air returned to the floor suction port to the surface to be cleaned and causing dust on the surface to be cleaned, but the power to the surface to be cleaned is not sufficient. It was not possible to use the refluxed air effectively.

The present invention has been made in view of the above-described drawbacks, and an object of the present invention is to provide a floor suction port that can efficiently use air refluxed at the floor suction port.

Since the notch groove 18 is formed in the position corresponding to the axial part 8, 9 of the rotary brush 10, the suction port flows in from the flow path 14 by the exhaust which flows into the rotary brush storage chamber 17. The dust in the air sucked from (6) is prevented from adhering to the bearing parts 8 and 9.

Since the exhaust gas flowing into the rotary brush accommodating chamber 7 from the flow passage 14 is air filtered by the cleaner body, dust does not adhere to the shaft portions 8 and 9 of the rotary brush 10, and the rotary brush ( It is possible to prevent the occurrence of vibration or noise during the operation of 10).

Therefore, in the reflux cleaner, it is possible to prevent dust from adhering to the shaft portions 8 and 9 of the rotary brush 10 by using exhaust, and to prevent dust from adhering to the shaft portions 8 and 9 to the outside. In comparison with the case, there is no need to provide a filter or the like, and the cost can be reduced.

In addition, since a part of the exhaust gas flowing through the flow passage 14 is discharged from the attachment portion 22 of the clamp 21, dust adhering to the attachment portion 22 of the clamp 21 is removed, and the clamp 21 is removed. The fall of the slidability can be prevented.

Next, the second embodiment will be described with reference to FIGS. 5 to 9.

However, the same parts as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

In addition, the air flowing into the side in which the safety switch 39 of the storage chamber 31 is accommodated prevents dust from adhering to the safety switch 39 and rotates through the cutout groove 18 of the partition wall 14. It flows into the brush storage chamber 7.

Since the notch groove 18 is formed in the position corresponding to the axial part 8 of the rotary brush 32, the suction opening 6 is exhausted by the exhaust which flows into the rotary brush storage chamber 7 from the storage chamber 31. The dust in the air sucked from the < RTI ID = 0.0 >) < / RTI > Exhaust flowing into the (7) prevents dust in the air sucked from the suction port 6 from adhering to the accumulator portion.

Since the exhaust air flowing into the rotary brush storage chamber 7 from the storage chamber 31 accommodating the safety switch 39 is air filtered from the cleaner body, it is possible to prevent malfunction due to dust adhering to the safety switch 39. At the same time, dust does not adhere to the shaft portion 8 of the rotary brush 32, and vibration, noise, and the like can be prevented from occurring while the rotary brush 32 is being driven.

Moreover, since the exhaust gas which flows into the rotary brush storage chamber 7 through the drive part storage chamber 37 from the storage chamber 31 which accommodated the electric motor 33 is air filtered by the cleaner body, At the same time, the rotary brush 32 can be driven reliably by preventing dust from adhering to the belt 36 and the pulley 34.

Therefore, in the reflux cleaner, it is possible to prevent dust from adhering to the shaft portions 8, 9 of the rotary brush 32 and the driving portions of the belt 36, the pulley 34, and the like by using the exhaust, and the rotary brush While idling and the like of (32) can be prevented, there is no need to install a filter or the like, and the cost can be reduced, as compared with the case of preventing dust from adhering to the storage unit.
