Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction port of a vacuum cleaner, and more particularly to a suction port structure suitable for cleaning a wooden floor.

[Prior art] The floor suction of a conventional vacuum cleaner is disclosed in Japanese Utility Model Publication No. 60-18417.
In general, a suction port is provided at the center as shown in Japanese Patent Application Laid-Open Publication No. H11-209, and a single brush is disposed at the front and rear portions of the suction port, and rollers and wheels for traveling on the floor are disposed. Alternatively, a configuration as described in Japanese Utility Model Application Laid-Open No. 61-10159, Japanese Utility Model Application No. 62-143461, or Japanese Utility Model Application Laid-Open No. 60-101048 provided with a suction port and a rotating roller with improved running and operability. It was connected.

[Problems to be solved by the invention]

In the above-mentioned prior art, no consideration was given to the treatment of cotton dust or the like wiped off by the brush portion and the reduction in suction operation force.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-described problems and to provide a suction port of a vacuum cleaner capable of efficiently collecting dust adhered to a brush after the dust has been wiped off by a brush unit.

[Means for solving the problem]

In order to achieve the above object, the present invention is characterized in that an outer case is formed by attaching an upper case to a lower case, and the lower case has a brush storage portion for storing a rotating brush, and a brush storage portion. A rotating brush, the rotation of which is restricted and the brush tip is disposed so as to be in contact with the inner wall of the brush accommodating portion; a front suction port formed forward and backward along the longitudinal direction of the rotating brush; A plurality of dust suction ports having a side suction port and communicating with the front suction port and the rear suction port on a part of an inner wall of the brush housing portion.

[Action]

According to the present invention, since the rotating brush provided in the brush storage portion is rotated, the operating force at the time of the opening operation of the suction opening on the carpet can be reduced, and the rotation of the rotating brush is restricted. Therefore, it is possible to wipe the floor surface with the rotation of the rotating brush locked.

Furthermore, since the tip of the brush of the rotating brush is in contact with the inner wall of the brush storage section, dust attached to the brush is rubbed against the inner wall of the brush storage section and is efficiently sucked from the front suction port or the rear suction port. Can be taken.

Furthermore, since a plurality of dust suction ports communicating with the front suction port and the rear suction port are formed in a part of the inner wall of the brush storage section, fine dust that has not been rubbed off by the inner wall of the brush storage section can be removed. Can be sucked through the suction port.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. A suction port 1 is composed of an upper case 2 and a lower case 3, and a bumper 4 for preventing damage to furniture and the like is arranged on the outermost periphery. In the lower case 3, the central rotating brush 5 is disposed so as to be capable of reciprocating swing within a range of 360 ° within the brush accommodating portion 14, and the tip of the brush when the reciprocating swing is performed. It is configured to be in contact with the inner wall of the storage unit 14, and a plurality of dust inlets 15 are provided in a part of the inner wall.

A front suction port 6 and a rear suction port 7 are provided on both sides in the longitudinal direction of the rotary brush 5 to be slightly longer than the rotary brush 5, and the front suction port 5 and the rear suction port 7 are merged inside. After passing through the suction passage 8, the upper case 2 and the lower case 3 are connected to a suction joint 12 which is rotatably held by the lower case 3 and communicates with the hose 10 and the extension pipe 11 on the cleaner 9 side.

Further, the lower case 3 includes a side brush 5a which is located outside the front suction port 6 and is the same as or more front than the front suction port, and a side brush which is the same as or more rear than the rear suction port 7. 5b is located.

 According to this embodiment, the following effects can be expected.

The central rotating brush moves counterclockwise to the rotation restricting position while moving to the front side of the suction port by the front-rear operation of the suction port, wipes the cotton dust at the stop position, and the wiped cotton dust returns when the suction port is pulled back. Next, wipe the cotton dust at the position where the rotating brush has moved to the clockwise rotation regulating position. Dust adhered to the brush when the rotating brush is inverted is rubbed against the inner wall of the brush storage portion, and can be efficiently sucked from the front or rear suction port, and the rotating brush can always be kept clean. .

Because the side brushes are arranged at the front, rear, left and right positions of the suction port, even when the suction port is used by tilting the front, rear, left and right during the suction operation, the hard part of the suction component base material does not directly touch the floor, Does not hurt even soft floors such as wooden floors.

Side suction passage 13 between the side brushes arranged on the left and right of the mouth
, Dust on the wall can be sucked.

Since there is no member in contact with the floor surface in front of the front suction port and rear of the rear suction port, dust can be effectively sucked from both the front and rear suction ports without pushing the dust.

Since the suction port is driven only by the brush, the vehicle can travel silently even on a wooden floor.

Since the suction flow can be sucked from the front, rear, left and right directions, the suction port can be operated with a small force even when connected to a vacuum cleaner having a large suction force.

In addition to the suction power, the floor surface can be cleaned with a brush as well as a cleaning effect.

〔The invention's effect〕

As described above, according to the present invention, since the rotating brush disposed in the brush storage portion is rotated, the operating force at the time of the initial opening operation of the mouth on the carpet can be reduced, and the rotating brush can be rotated. Since the movement is restricted, the floor surface can be wiped while the rotation of the rotating brush is locked.

Furthermore, since the tip of the brush of the rotating brush is in contact with the inner wall of the brush storage section, dust attached to the brush is rubbed against the inner wall of the brush storage section and is efficiently sucked from the front suction port or the rear suction port. Can be taken.

Furthermore, since a plurality of dust suction ports communicating with the front suction port and the rear suction port are formed in a part of the inner wall of the brush storage section, fine dust that has not been rubbed off by the inner wall of the brush storage section can be removed. The suction can be performed through the suction port, so that dust attached to the rotating brush can be prevented from being damaged on a wooden floor or the like.
