However, since these suction tools cover the entire lower surface of the suction tool body with a rag or a mop,
Dust adheres to a rag or mop without being sucked by the vacuum cleaner.During the cleaning operation, the dust moves on the surface to be cleaned while adhering to the rag or mop, and damages the surface to be cleaned. is there. In addition, since the suction resistance increases due to the rag or mop, and the suction amount of the cleaner body decreases, there are disadvantages such as a decrease in dust suction capability and an overload applied to the electric blower.

Accordingly, the applicant of the present application has proposed a suction device in which suction ports are arranged in front and rear on the bottom surface of the suction device main body and a wiping member is mounted on the rear suction port in Japanese Patent Application No. 7-104429. In this suction tool, a wiping member is provided at the rear intake port so as to be movable up and down, and when cleaning a flooring or the like, the wiping member is projected from the intake port, dust is sucked from front and rear intake ports, and a wiping member is provided. At the same time, dust is adsorbed and the operation of wiping the flooring or the like is performed at the same time. When cleaning a tatami mat, a carpet, or the like, the wiping member is housed in a rear intake port, and dust is absorbed from a front intake port so that the wiping member does not touch the surface to be cleaned.

However, in this configuration, the wiping member is only moved up and down to the end. Therefore, when cleaning a carpet or the like, even if the wiping member is stored in the rear air inlet, the wiping member is not cleaned. The surface may come into contact with the wiping member, unnecessarily soiling the wiping member, or the surface to be cleaned may be stained by dirt attached to the wiping member.

The fine fibers are subjected to electrostatic treatment in order to further improve dust retention.

A wiping member 31 is constituted by the support 27, the elastic body 29 and the cloth 30.

Reference numeral 32 denotes a position for covering the lower surface of the wiping member 31,
With a cover rotatably disposed at a position where the lower surface of the wiping member 31 is exposed, both ends of the cover 32 are supported by the axle 12, and one end of the cover 32 and the axle 12 A spring 37 is provided between the operating lever 13 and the cover 32 so that the cover 32 rotates in conjunction with the operation of the operating lever 13.

The movement of the cover 32 and the movement of the wiping member 31 are interlocked with the operation of the operation lever 13.
The cam 15 is configured to push down the wiping member 31 when the cover 32 is moved from a position covering the wiping member 31 by operating the operation lever 13 (see FIGS. 4 and 5).
As a result, the wiping member 31 does not interfere with the cover 32 during movement of the cover 32 and is prevented from moving.

The cover 32 is made of a synthetic resin having low frictional resistance, and is formed in a substantially arc-shaped cross section. The cover 32 covers the wiping member 31, that is, improves the mobility when cleaning a carpet or the like. It is supposed to.

When the lower position is located above the lower surface of the wiping member 31, the wiping member 31 is stored in the storage portion 20, and the cover 32 is positioned on the bottom surface of the suction tool main body 1, the lowermost position of the front wheels 34 and the wheels 11 is set. The position is substantially flush with the lowermost position of the cover 32.

Reference numeral 35 denotes a substrate storage chamber 8 at the rear of the suction tool main body 1.
The rotary switch 36, which is a detection unit, is protruded from the position adjacent to the storage unit 20 to the bottom surface of the suction tool main body 1. The safety switch 35 is connected to the suction tool main body 1.
When the is grounded to the surface to be cleaned, the rotating roller 36 is pushed by the surface to be cleaned and moves in the direction of the suction tool main body 1, and the safety switch 35 is operated so that the electric motor 6 for driving the rotating brush 16 can be driven. At the same time, when the suction tool main body 1 is lifted from the surface to be cleaned, the rotating roller 36 moves in a direction protruding from the suction tool main body 1, and the safety switch 35 is operated so that the electric motor 6 cannot be driven. ing.

The rotating roller 36 is located above the lower surface of the wiping member 31 with the wiping member 31 protruding from the bottom surface of the suction tool main body 1 and the rotating roller even when the suction tool main body 1 is in contact with the surface to be cleaned. 36 does not touch the surface to be cleaned, and the rotating brush 16
The driving of the driving motor 6 is disabled.

On the other hand, when the wiping member 31 is stored in the storage section 20 and the cover 32 is positioned below the storage section 20, the rotating roller 36 positioned in the notch 33 of the cover 32 is positioned below the lower surface of the cover 32. The electric motor 16 can be driven by projecting and grounding the suction tool main body 1 to the surface to be cleaned. The electric motor
16 is operated by a hand switch of a vacuum cleaner (not shown).

The operating lever 13 is operated to operate the shaft.
When the rotation of the operation lever 13 is performed, the cam 15 is interlocked and pushes the base 23 downwardly against the urging force of the spring 26 so that the cover 32 is moved downward by the rotation of the operation lever 13. The base 23 is rotated backward to expose the base 23.

In this state, the lower part of the elastic body 29 is covered with the cloth-like body 30, and both ends of the cloth-like body 30 are hooked and locked on a large number of fibrous bodies of the locking member 28 provided on the support 27. In this state, the support 27 is locked on the base 23, and the wiping member 31 is mounted on the base 23.

When cleaning a surface to be cleaned, such as a flooring, which requires wiping cleaning, the operation lever 13 is moved to the suction tool main body 1.
When operated forward, the cover 32 rotates rearward of the suction tool main body 1 in conjunction with the rotation of the operation lever 13, so that the lower portion of the storage portion 20 is opened, and the camshaft 14 and the cam 15 face downward. And rotate the wiping member 31 as shown in FIG.
Is pressed down so as to be exposed on the bottom surface of the suction tool main body 1.

At this time, after the cover 32 is opened by operating the operation lever 13, the wiping member 31 is pushed down by the cam 15 below the suction tool main body 1. This prevents the member 31 from interfering with the cover 32 and preventing its movement, thereby preventing malfunction such as the cover 32 being caught by the wiping member 31 and not being opened.

When the wiping member 31 is projected downward from the suction tool main body 1, the wiping member 31 is rotated by the rotating roller of the safety switch 35.
Since the rotary brush 16 is positioned below 36, the rotary brush 16 does not rotate even if the switch of the rotary brush 16 driving motor 6 is operated by mistake, and the wiping member 31 is exposed toward the surface to be cleaned. Even when the rotary brush 16 is driven to clean the carpet or the like, the rotary brush 16 is not driven, so that the user can recognize the use.

When the suction tool main body 1 is moved forward in this state, the suction tool main body 1 is strongly pressed against the surface to be cleaned. Conversely, when the suction tool main body 1 is moved rearward, the suction tool main body 1 is slightly lifted. Therefore, the wiping operation is mainly performed when the suction tool main body 1 is moved forward. In this state, relatively large dirt and dust are sucked from the suction port 9, and fine dust is removed by the wiping member 31. While being collected by the cloth body 30, oil stains and the like adhering to the surface to be cleaned are wiped off by the wiping member 31. Cloth
In No. 30, since the fibers are subjected to electrostatic treatment, dust collecting performance is further improved.

Since the wiping member 31 is disposed at a position adjacent to the intake port 9 and does not cover the intake port 9, sufficient air for cooling the electric blower of the cleaner body can be sucked. Overload can be prevented.

Since both ends of the cloth-like body 30 are locked by the locking member 28 and are sandwiched between the base 23 and the support 27, the cloth 30 is separated from the support 27 by a push-pull operation accompanying cleaning. Of the cloth-like body 30 can be prevented.

When the wiping member 31 is located on the bottom surface side of the suction tool main body 1, the front wheel 34 and the wheel 11 are in a floating state, and even if sand or the like falls, the sand or the like is pushed by the two wheels 34 and 11. Thus, it is sucked into the cleaner body from the air inlet 9 without damaging the surface to be cleaned.

When the cloth 30 becomes dirty, the wiping member 31 is pressed down from the bottom surface of the suction tool main body 1 and the support 27 is pulled to remove the cloth 30 and replace it with a new cloth 30.

If there is no cloth-like body 30 to be replaced, the wiping operation is performed with the wiping member 31 with the cloth-like body 30 removed and mounted on the base 23. When the cloth member 30 is removed, the elastic member 29 comes into contact with the surface to be cleaned, and
Since the brushed body 29 is used, the surface to be cleaned can be wiped and cleaned by the elastic body 29. Since the wiping member 31 is configured to be detachable from the base 23, the cleaning member 31 can be removed from the base 23 to clean the elastic body 29 after the surface to be cleaned is cleaned by the elastic body 29. .

When cleaning a surface to be cleaned such as a tatami mat or a carpet,
When the operation lever 13 is operated toward the rear side of the suction tool main body 1, the camshaft 14 and the cam 15 rotate upward in conjunction with the rotation of the operation lever 13, and as shown in FIG. The wiping member 33 is moved by the force to the storage portion of the suction tool main body 1.
The cover 32 is rotated in front of the suction tool main body 1 and is positioned below the storage section 20 while being housed in the housing 20, and the wiping member 31 is covered.

In this state, the rotating roller 36 of the safety switch 35 is located at the notch 33 of the cover 32 and protrudes below the lower surface of the cover 32, and the safety switch 35 is activated by grounding on the surface to be cleaned. The rotating brush 16 can be driven.

In the housed state of the wiping member 31, the front wheel 34
In addition, the wheels 11 are in contact with the surface to be cleaned, and the mobility of the suction tool main body 1 is improved. Further, since the cover 32 located on the bottom surface side of the suction tool main body 1 is formed in a substantially arc-shaped cross section, the contact resistance with the surface to be cleaned is reduced, and the cover 32 is made of synthetic resin having low friction resistance. Since it is formed, mobility when cleaning a carpet or the like is further improved.

When cleaning unnecessary tatami mats or carpets with the wiping member 31, the wiping member 31 is stored in the storage portion 20, so that the cloth 30 of the wiping member 31 comes into contact with the surface to be cleaned. The wiping member 31 is not unnecessarily stained, and the wiping member 31 is not stained on the carpet or the like, and the carpet or the like is not stained.

In this embodiment, the cover 32 is formed of a synthetic resin having low frictional resistance.
A configuration may be adopted in which a low friction resistance material is adhered to (the surface facing the surface to be cleaned).
