[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vacuum cleaner suction tool and a vacuum cleaner that are intended to improve dust collection performance and provide a light operational feeling.
[0002]
[Prior art]
Conventionally, there is a vacuum cleaner suction tool as disclosed in JP-A-7-8425, which will be described with reference to FIGS.
[0003]
Reference numeral 60 denotes a suction tool body, which is configured via a bumper 4 which is a cushioning material formed of a soft material between the upper member 2 and the lower member 3. In addition, there is an arm 5 that is rotatably held between the upper member 2 and the lower member 3 at the substantially center of the suction tool body 60, and the arm 5 is connected to a vacuum cleaner (not shown). A pipe 6 is rotatably provided. The arm 5 to the pipe 6 have a series of communication holes, and dust passes through the communication holes and is collected by an electric vacuum cleaner (not shown).
[0004]
In front of the suction tool main body 60, there is a suction chamber 12 which is an entrance for sucking dust in the lower opening, and a rotary brush 61 for scooping up dust existing on the surface to be cleaned is rotatably provided inside the suction chamber 12. It has been. A suction port 7 is provided for communicating the suction chamber 12 with the arm 5 and the pipe 6.
[0005]
In addition, a room-like space that is divided into left and right by the arm 5 is provided behind the suction tool main body 60, and a driving chamber in which a motor 10 that is a driving device for rotating the rotating brush 61 is provided on one side. There are eight. In addition, a control circuit 11 for controlling the motor 10 is provided in a control chamber 9 in a direction opposite to the drive chamber 8. Further, the driving force of the motor 10 is transmitted, so that the rotary brush 61 is driven to rotate.
[0006]
As shown in FIG. 20, the rotating brush 61 that is driven to rotate by the motor 10 includes a rod-shaped base material 64 that forms the central portion of the rotating shaft of the rotating brush 61, and a groove that is spirally provided on the outer periphery of the base material 64. 69 is provided. The groove 69 is open toward the outer peripheral surface of the substrate 64. A series of bristle brushes 65 that collect dust on the surface to be cleaned along the grooves 69 are implanted in the base material 64. On one end face of the blade 66 that collects dust on the surface to be cleaned, there is a base body 70 fitted and inserted into the groove 69. Further, the blade 66 includes a strip-like fin 67 provided so as to protrude from the base body 70 toward the outside of the base material 64, and the tip 68 of the fin 67 has a bristle brush 65. It is provided to be bent so as to be close to.
[0007]
A pulley die 63, which is a pedestal provided with a gear for transmitting the rotational drive of the motor 10, is press-fitted and fixed to one end of the base material 64. A bearing a 62 is provided at the end of the pulley die 63 so as to pivotally support the rotary brush 61 so that it can freely rotate in the suction chamber 12. Similarly, the other end of the base material 64 is provided with a bearing b72 that supports the rotating brush 61 so that the rotating brush 61 can freely rotate. The bearing support 71 serves as a pedestal that supports the bearing b72. Is provided.
[0008]
Another conventional example will be described with reference to FIG. In addition, the same code | symbol is attached | subjected about the same component as said conventional example, and the description is abbreviate | omitted.
[0009]
Reference numeral 73 denotes a rotating brush that is rotationally driven on the surface to be cleaned and wipes and collects dust by separating and collecting, and a straight rod-like base material 74 is provided as the center of the rotating shaft of the rotating brush 73. The base material 74 is provided with a plurality of grooves 69 extending straight in the longitudinal direction.
[0010]
A bristle brush 65 planted over the entire circumference is provided on the outer circumference of the base material 74 divided by the groove 69. Reference numeral 66 denotes a blade, which is provided with a base body 70 at one end surface and a fin 67 provided in a fin shape at the opposite end, and a tip portion 68 of the fin 67 is provided lower than the total height of the bristle brush 65. Yes.
[0011]
The suction tool main body 60 including the rotating brush 61 configured as described above performs a cleaning operation on the surface to be cleaned while rotating the rotating brush 61. At this time, since the gap between the tip 68 of the fin 67 that protrudes the blade 66 preceding the bristle brush 65 outward from the base 64 and the bristle brush 65 is small, long fiber dust such as lint is bristle. Biting into the brush 65 and entanglement with the base material 64 can be prevented.
[0012]
In the case where the rotary brush 61 rotates and the blade 66 precedes the bristle brush 65, the fin 67 has an air resistance when the rotary brush 61 rotates like a back vane in the centrifugal fan with respect to the rotation direction. Work to be less. Therefore, even if the rotating brush 61 rotates at a high speed, vibration can be suppressed, so that noise can be reduced.
[0013]
[Problems to be solved by the invention]
In the conventional vacuum cleaner suction tool as described above, in order to prevent the long fiber dust from being wound around the rotating brush 61 and to reduce the air resistance when the rotating brush 61 rotates, the blade 66 is mounted on the blade 66. In addition, since the fin 67 that bends is provided, even if the fin 67 of the blade 66 spreads by centrifugal force when the blade 66 comes into contact with the carpet, the fin 67 comes into contact with the bristle brush 65 in advance. The tip of the fin 67 hits the top of the carpet.
[0014]
Prior to abutting the carpet, the blade 66 is such that the blade 66 stands perpendicular to the groove of the substrate 64. When the blade 66 hits the carpet, the blade 66 is deformed into a bent shape like the fin 67 on the surface of the carpet. However, the blade is only deformed and a force to return to a shape standing perpendicular to the original groove. Work. Since the rotating brush 61 is rotating, the blade 66 that is in contact with the carpet surface has a moment of separation from the carpet surface. At that time, the force that the blade 66 is bent to return from the deformation causes the surface of the rotating brush 61 to rotate. It will be fried together with the rotational force.
[0015]
As described above, the blade 66 having the bent fin 67 has a weaker force for lifting the carpet surface than the blade 66 standing perpendicular to the groove, and therefore, the effect of separating dust from the pile-like surface to be cleaned such as a carpet. May become weak and the dust collection performance may be lowered.
[0016]
Further, when the rotary brush 61 is rotated forward from the front to the rear with respect to the suction tool main body 60, the force to lift the pile from the front to the rear by the rotary brush 61 particularly on the pile-shaped surface to be cleaned. Therefore, it cannot be used as a self-propelled mechanism that reduces the force required when operating the suction tool body 60 on the surface to be cleaned.
[0017]
The present invention is intended to solve the conventional problems as described above, has high dust collection performance, can efficiently perform cleaning work, and obtains a light operation feeling on the pile-shaped surface to be cleaned. It aims at providing the suction tool for vacuum cleaners, and a vacuum cleaner.
[0018]
[Means for Solving the Problems]
In order to solve the above problems, the present invention includes a suction chamber having a lower opening, a rotating brush rotatably disposed in the suction chamber, and a drive source for driving the rotating brush to rotate. A rod-shaped base material, a bristle brush attached to the outer periphery of the base material, and an auxiliary blade formed of an elastic material and provided in the counter-rotating direction of the bristle brush to restrict the amount of collapse of the bristle brush. The bristle brush is configured to come into contact with the tip of the auxiliary blade when it contacts the surface to be cleaned by rotation and deforms to some extent, and then bends only from the position where the tip of the auxiliary blade comes into contact to the tip. It was characterized.
[0019]
As a result, it is possible to clean the floor while rotating the rotating brush with the wiping effect of the bristle brush on the floor, and when rotating the rotating brush to clean the pile-like surface to be cleaned such as carpet, A bristle brush hits the surface and is bent and deformed from the base of the bristle brush at first, but when the bristle brush is deformed to some extent, the tip of the auxiliary blade comes into contact with the bristle brush. As a result, the bristle brush bends only from the position where the tip of the auxiliary blade comes into contact to the tip, and the time for the bristle brush to return to its original shape from the bent shape is shortened, and the bristle brush has a rigid strength against bending. Improves the appearance and rakes the pile surface with a stronger force. Thereby, when the suction brush main body is operated in the pile-shaped surface to be cleaned, when the rotation direction of the rotary brush rotates in the same direction with respect to the direction in which the suction tool main body is pushed forward, the rigidity is improved. Since the bristle brush can forcefully push the pile from the front to the rear, the suction tool main body has the effect of self-propelling forward, and the pile-shaped surface to be cleaned can be operated lightly. Further, if the pile surface is pushed strongly, the dust collecting performance can be improved because it is a force to peel off the dust adhering to the pile surface.
[0020]
Therefore, although it is a rotating brush provided with a bristle brush, it becomes a suction tool main body with a good dust collecting property not only on the floor but also on the pile surface.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 of the present invention is
In order to solve the above problems, the present invention includes a suction chamber having a lower opening, a rotating brush rotatably disposed in the suction chamber, and a drive source for driving the rotating brush to rotate. A rod-shaped base material, a bristle brush attached to the outer periphery of the base material, and an auxiliary blade formed of an elastic material and provided in the counter-rotating direction of the bristle brush to restrict the amount of collapse of the bristle brush. The bristle brush is configured to come into contact with the tip of the auxiliary blade when it contacts the surface to be cleaned by rotation and deforms to some extent, and then bends only from the position where the tip of the auxiliary blade comes into contact to the tip. It was characterized.
[0022]
As a result, it is possible to clean the floor while rotating the rotating brush with the wiping effect of the bristle brush on the floor, and when rotating the rotating brush to clean the pile-like surface to be cleaned such as carpet, A bristle brush hits the surface and is bent and deformed from the base of the bristle brush at first, but when the bristle brush is deformed to some extent, the tip of the auxiliary blade comes into contact with the bristle brush. As a result, the bristle brush bends only from the position where the tip of the auxiliary blade comes into contact to the tip, and the time for the bristle brush to return to its original shape from the bent shape is shortened, and the bristle brush has a rigid strength against bending. Improves the appearance and rakes the pile surface with a stronger force. Thereby, when the suction brush main body is operated in the pile-shaped surface to be cleaned, when the rotation direction of the rotary brush rotates in the same direction with respect to the direction in which the suction tool main body is pushed forward, the rigidity is improved. Since the bristle brush can forcefully push the pile from the front to the rear, the suction tool main body has the effect of self-propelling forward, and the pile-shaped surface to be cleaned can be operated lightly. Further, if the pile surface is pushed strongly, the dust collecting performance can be improved because it is a force to peel off the dust adhering to the pile surface.
[0023]
Therefore, although it is a rotating brush provided with a bristle brush, it becomes a suction tool main body with a good dust collecting property not only on the floor but also on the pile surface.
[0024]
In addition, since the gap between the tip of the auxiliary blade and the side of the bristle brush is set small, long fiber dust entering the root part of the bristle brush and the substrate is prevented as in the conventional effect. It is possible to make it difficult to wind long fiber dust around the rotating brush itself.
[0025]
Claim 2 The invention described is provided with an electric blower chamber in which an electric blower is arranged at the rear, a dust collection chamber in which a dust collection bag for collecting dust is arranged at the front, and a dust collection port for communicating the dust collection chamber with outside air. An electric vacuum cleaner main body comprising a lower main body case to be formed, a main body case covering the electric blower chamber, and a lid covering an upper opening of the dust collecting chamber. Item 1 Since the vacuum cleaner suction tool is provided, dust collection and light cleaning work can be performed regardless of the surface to be cleaned.
[0026]
【Example】
Example 1
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0027]
Reference numeral 1 denotes a suction tool body, which is configured via a bumper 4 that is a cushioning material formed of a soft material between the upper member 2 and the lower member 3. In addition, there is an arm 5 that is pivotally held by the upper member 2 and the lower member 3 at the approximate center of the suction tool body 1, and the arm 5 is connected to a vacuum cleaner (not shown). A pipe 6 is rotatably provided. A series of communication holes 78 are provided from the arm 5 to the pipe 6, and dust passes through the communication holes 78 and is collected by an electric vacuum cleaner (not shown).
[0028]
In front of the suction tool body 1, there is a suction chamber 12 which is an entrance for sucking dust in the lower opening, and a rotary brush 13 for collecting dust existing on the surface to be cleaned is rotatable inside the suction chamber 12. Is provided. A suction port 7 is provided for communicating the suction chamber 12 with the arm 5 and the pipe 6.
[0029]
In addition, a room-like space divided into left and right by the arm 5 is provided behind the suction tool main body 1, and a driving chamber in which a motor 10 that is a driving device for rotating the rotating brush 13 is provided on one side. There are eight. In addition, a control circuit 11 for controlling the motor 10 is provided in a control chamber 9 in a direction opposite to the drive chamber 8. Further, the driving force of the motor 10 is transmitted to drive the rotary brush 13 to rotate.
[0030]
In the rotating brush 13 that is rotationally driven by the motor 10, there is a substantially rod-shaped base material 21 as the rotation center axis of the rotating brush 13. On the surface of the base material 21, a positive multiple of groove bands 75 opening toward the surface of the base material 21 are provided in the longitudinal direction, and the base material 21 is spirally twisted together with the groove bands 75.
[0031]
In addition, the bristle brush 18 having a role of wiping on the floor or the like and the peripheral blade 17 having a function of separating dust from the carpet pile are alternately provided on the base material 21. A base body 76 is provided for inserting one end of the peripheral blade 17 into the groove band 75 and fixing it to the base material 21. Further, the auxiliary blade 16 bonded and fixed to the surface portion of the base material 21 sandwiched between at least the front surface portion with respect to the rotational direction of the peripheral blade 17 and the rear surface of the bristle brush 18 adjacent to the rotational direction of the rotating brush 13. Is provided so as to extend toward the rear surface of the bristle brush 18.
[0032]
A pulley die 15, which is a pedestal provided with a gear for transmitting the rotational drive of the motor 10 via a belt (not shown), is press-fitted and fixed to one end of the base material 21. Further, a bearing a <b> 14 is provided at the end of the pulley die 15 so as to pivotally support the rotating brush 13 so that the rotating brush 13 can freely rotate in the suction chamber 12. Similarly, the other end of the base material 21 is provided with a bearing b20 that pivotally supports the rotary brush 13 so as to freely rotate, and the bearing support 19 serves as a pedestal that pivotally supports the bearing b20. Is provided.
[0033]
The operation of the above configuration is as follows.
[0034]
Due to the wiping effect of the bristle brush 18 on the floor, the floor can be cleaned while the rotating brush 13 is rotated.
[0035]
Further, when the rotary brush 13 is rotated in order to clean the pile-like surface to be cleaned such as a carpet, the bristle brush 18 hits the pile surface and is bent and deformed from the root of the bristle brush 18 at first. When the bristle brush 18 is deformed to some extent, the tip of the auxiliary blade 16 comes into contact with the bristle brush 18. As a result, the bristle brush 18 is bent only from the position where the tip of the auxiliary blade 16 abuts to the tip, and the time for the bristle brush 18 to return to the original shape from the bent shape is shortened. Stiffness against bending is apparently improved, and the pile surface is lifted with a stronger force.
[0036]
Further, in the case of the peripheral blade 17, the pile surface is lifted by the force that works to return to the original vertical shape and the rotational force of the rotary brush 13 once it hits the pile and bends and deforms.
[0037]
As described above, when the rotation direction of the rotary brush 13 rotates in the same direction as the direction in which the suction tool body 1 is pushed forward by the action of the bristle brush 18 and the peripheral blade 17, the pile-shaped cleaning is performed. When the suction tool main body 1 is operated on the surface, the bristle brush 18 and the peripheral blade 17 with improved rigidity can alternately push the pile strongly from the front to the back, so that the suction tool main body 1 runs forward. An effect is produced and the pile-shaped surface to be cleaned can be operated lightly.
[0038]
Further, if the pile surface is pushed strongly, the dust collecting performance can be improved because it is a force to peel off the dust adhering to the pile surface.
[0039]
Therefore, although it is the rotary brush 13 provided with the bristle brush 18 and the surrounding blade 17, the thing excellent in dust collection property not only on a floor but a pile surface can be performed.
[0040]
Further, since the gap between the tip of the auxiliary blade 16 and the side surface of the bristle brush 18 is set to be small, long fiber dust is formed at the root part of the bristle brush 18 and the base material 21 as in the effect of the prior art. Can be prevented and long fiber dust can hardly be wound around the rotating brush 13 itself.
[0041]
(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0042]
The auxiliary blade 23 is formed integrally with the peripheral blade 22 via a connecting body 77 extending along the outer periphery of the base material 21. Then, the peripheral blade 22 and the bristle brush 18 are passed through and fixed to the groove body 75 provided in the base material 21 at one end thereof.
[0043]
The effects of the above configuration are as follows.
[0044]
When the connection body 77 for connecting the auxiliary blade 23 from the portion joined to the base material 21 and the peripheral blade 22 is formed so as to cover the base material 21, when solid matter such as screws and pins is collected. The solid matter that has been scraped up by the peripheral blade 22 is splashed toward the base material 21. At this time, the solid matter hits the connection body 77, and there is an effect of directly protecting the vicinity of the substrate 76 of the base material 21 and the peripheral blade 22. Since the base member 21 and the peripheral blade 22 are protected by the connection body 77, the durability of the rotating brush 24 is improved and it can withstand a more severe use environment.
[0045]
In addition, since the auxiliary blade 23 is attached together with the peripheral blade 22 when the peripheral blade 22 is attached to the base material 21, the time for producing the rotating brush 24 can be shortened and the cost can be reduced because it can be produced integrally in the manufacture of the parts. is there.
[0046]
(Example 3)
Next, a third embodiment of the present invention will be described with reference to FIG. The same components as those in the first or second embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0047]
The rotary brush 27 that is driven to rotate by the motor 10 and collects dust on the surface to be cleaned has a groove that is provided on the base member 21 and has a function of separating dust from the carpet pile. A bristle brush 18 having a wiping function on the blade 25 and the floor is inserted and fixed through a base 76 provided at one end of each.
[0048]
A rib-like auxiliary blade 26 extending toward the bristle brush 18 is formed on the front surface and the rear surface of the peripheral blade 25 with respect to the rotation direction of the rotary brush 27, and the peripheral blade 25 and the auxiliary blade The cross-sectional shape of the blade 26 is formed in a substantially crossed shape.
[0049]
The effects of the above configuration are as follows.
[0050]
When the auxiliary blade 26 provided on the rear surface of the peripheral blade 25 deforms to some extent when the peripheral blade 25 hits the surface to be cleaned and deforms to some extent, the auxiliary blade 26 on the rear surface hits the base material 21 and the deformation amount of the peripheral blade 26 is reduced. regulate. Therefore, the same effect as that obtained when the bristle brush 18 is brought into contact with the auxiliary blade 26 to enhance the rigidity can be obtained, and the rigidity of the peripheral blade 26 can be enhanced.
[0051]
This makes it possible to collect finer dust by using a material that enhances the lifting force by the circumferential blade 26, particularly the pile-shaped surface to be cleaned, and reduces the rigidity of the circumferential blade 26 and increases the adhesion. However, it is possible to improve a light operation feeling and dust collection without reducing the lifting force.
[0052]
Example 4
Next, a fourth embodiment of the present invention will be described with reference to FIG. The same components as those in the first to third embodiments are denoted by the same reference numerals, and the description thereof is omitted.
[0053]
The rotating brush 33 that is driven to rotate by the motor 10 and collects dust on the surface to be cleaned has a groove that is provided on the base member 21 and has a function of separating dust from the carpet pile. A bristle brush 18 having a wiping function on the blade 28 and the floor is inserted and fixed through a base 76 provided at one end of each.
[0054]
There is an auxiliary blade 29 provided on the front surface and the rear surface of the circumferential blade 28 in the longitudinal direction so as to be cross-shaped.
[0055]
The auxiliary blade 29 was provided by opening a space between a base portion where the base material 21 and the peripheral blade 28 were joined so that a space portion b was formed between the auxiliary blade 29 and the base material 21. A space surrounded by the bristle brush 18, the peripheral blade 28, the auxiliary blade 29, and the surface to be cleaned was defined as a space a.
[0056]
The operation of the above configuration is as follows.
[0057]
On the surface to be cleaned, the cross-sectional area of the space a can be reduced as compared with the case where the auxiliary blade 29 is not provided. For this reason, in the rotating brush that is rotating, the air in the space a is repeatedly sealed at a predetermined interval when touching the surface to be cleaned and released when leaving the surface to be cleaned. Thereby, if the cross-sectional area of the space part a is large, the amount of air to be sealed is large, and a roaring sound is generated to give vibration to the rotating brush 33 by repeatedly sealing and opening. Therefore, by reducing the cross-sectional area of the space portion a surrounded by the bristle brush 18, the peripheral blade 28, the auxiliary blade 29, and the surface to be cleaned, the amount of air that is sealed and released is reduced, and the vibration of the rotary brush 33 is reduced. Even if the rotating brush 33 is rotated on the floor, it can be suppressed to extremely low noise.
[0058]
(Example 5)
Next, a fifth embodiment of the present invention will be described with reference to FIG. The same components as those in the first to fourth embodiments are denoted by the same reference numerals, and the description thereof is omitted.
[0059]
The rotating brush 36 that is driven to rotate by the motor 10 and collects dust on the surface to be cleaned has a groove that is provided in the base member 21 and has a function of separating dust from the carpet pile. A bristle brush 35 having a wiping function on the blade 34 and the floor or the like is inserted and fixed through a base 76 provided at one end of each.
[0060]
There is an auxiliary blade 35 provided on the front surface and the rear surface of the circumferential blade 34 in the longitudinal direction so as to be cross-shaped. Further, the tip of the auxiliary blade 35 is surely brought into contact when the bristle brush 18 is bent.
[0061]
The effect | action by the said structure is as follows.
[0062]
When the rotating brush 36 is rotated on the floor, the bristle brush 18 is also slightly bent. At this time, when the auxiliary blade 35 comes into contact with the bristle brush 18, the rigidity of the bristle brush 18 is improved as described in the first embodiment. However, in this case, since the bristle brush 18 touches the surface to be cleaned and comes into contact with the auxiliary blade 35 at an early stage, the bristle brush 18 having a strong rigidity is rubbed strongly on the floor, particularly on the floor. Furthermore, the suction tool body 1 is smoothly operated on the floor because of the self-propelled property that the bristle brush 18 kicks strongly on the floor surface when the floor brush is polished well and the rotating brush 36 is rotating forward. It can be done.
[0063]
(Example 6)
Next, a sixth embodiment of the present invention will be described with reference to FIG. The same components as those in the first to fifth embodiments are denoted by the same reference numerals, and the description thereof is omitted.
[0064]
A rotating brush 39 that is driven to rotate by the motor 10 and collects dust on the surface to be cleaned has a groove that is provided on the base member 21 and has a function of separating dust from the carpet pile. A bristle brush 18 having a wiping function on the blade 37 and the floor is inserted and fixed through a base 76 provided at one end of each.
[0065]
Auxiliary blades 38 are provided on the front and rear surfaces of the circumferential blade 37 in the longitudinal direction so as to be cross-shaped.
[0066]
Further, the auxiliary blade 38 provided on the peripheral blade 37 and the rotary brush 39 are provided so as to contact with each other at half or less of the total height of the adjacent bristle brush 18 when the rotary brush 39 rotates.
[0067]
The operation of the above configuration is as follows.
[0068]
When the peripheral blade 37 touches the surface to be cleaned and bends, the auxiliary blade 38 has a shape in which the front surface of the peripheral blade 37 protrudes toward the surface to be cleaned. In particular, on the tatami mat or the like, the auxiliary blade 38 may cause the eyes of the tatami mat to cause scratches. However, if the auxiliary blade 38 is brought into contact with the bristle brush 18 at a height h / 2 or less, the peripheral blade 38 may be damaged. Since the tip of the auxiliary blade 38 does not protrude from the radius when the blade 37 rotates, the rotary brush 39 can be rotated and used without scratching the surface to be cleaned.
[0069]
(Example 7)
Next, a seventh embodiment of the present invention will be described with reference to FIG. The same components as those in the first to sixth embodiments are denoted by the same reference numerals, and the description thereof is omitted.

The bristle brush 18 is provided so as to extend toward the rear surface.
[0072]
Further, the tip outer diameter R1 at the center of the peripheral blade 40 is made smaller than the outer diameter R2 at the both ends of the peripheral blade 40 in the full length direction of the peripheral blade 40 when the rotary brush 41 rotates.
[0073]
The operation of the above configuration is as follows.
[0074]
Even when the rotary brush 41 is rotating when the surface portion of the surface to be cleaned sticks to the lower surface of the suction tool main body 1 and enters the surface portion of the surface to be cleaned in the suction chamber 12, in the vicinity of the central portion of the rotary brush 41. Since the diameter at the time of rotation of the peripheral blade 40 is small, the peripheral blade 40 does not hit the surface to be cleaned more than necessary, so that the surface to be cleaned is not damaged. Further, it is assumed that the suction tool main body 1 is operated by rotating the rotary brush 41 on the flooring. At this time, the intake air generated in the vicinity of the suction port 7 is strong, and the intake air at both ends of the suction chamber 12 is weakened. That is, wind flows through a gap formed between the suction tool main body 1 and the flooring, and the flow of the wind tends to gradually weaken from the front and rear central portions of the suction tool main body 1 toward the left and right ends. There is. Naturally, there is also a flow of air that is sucked through the gap between the peripheral blade 40 of the rotating brush 41 and the flooring, so that the peripheral blade 40 rotates at a central portion of the peripheral blade 40 where the wind is strong. As a result, the wind flow may be disturbed at a constant rate, which may generate a sound like a wind. This is done by shortening the vicinity of the central portion of the peripheral blade 40 to ensure a wind flow path, and by making the both ends longer than the central portion, the amount of wind flowing between the peripheral blade 40 and the flooring By making the air flow uniform, it is possible to prevent wind noise.
[0075]
Further, on the surface to be cleaned as described above, the torque required for rotationally driving the rotary brush 41 can be reduced. If the motor is driven, durability is improved by preventing deterioration of the motor. It is possible to prevent the dust collection performance from being lowered due to the decrease in the rotational speed.
[0076]

[0077]
Along with the groove 75 provided in the base material 45 that forms the center of the rotation axis of the rotary brush 46, the base material 45 is provided so as to be twisted so as to be V-shaped at a substantially central portion.
[0078]
Since the groove body 75 is provided on the V-shape, the peripheral brush 42 having a function of separating dust from the carpet pile and the bristle brush 46 having a function of wiping on the floor or the like are provided at each end. In order to insert and fix the base body 76 provided along the groove body 75, it is configured in a V shape.
[0079]
The operation of the above configuration is as follows.
[0080]
When the dust on the surface to be cleaned is lifted up by the rotating brush 46, the action of repelling the dust toward the center of the rotating brush 46 works, the dust is directly sucked, and extremely efficient dust collecting work can be performed.
[0081]
Example 9

Embodiments 1 to 8 described above include a vacuum cleaner main body 55 comprising a main body case lower 52 that forms an upper surface, a main body case upper 53 that covers the electric blower chamber 48, and a lid 54 that covers the upper opening of the dust collection chamber 50. In order to connect the suction tool main body 1 according to any one of the above to the dust collection port 51, a hose 57 made of a soft material and a connection body 56 provided at one end of the hose 57 are provided with a dust collection It is provided so as to be connected to the mouth 51.
[0083]
A hand 58 for controlling the cleaner main body 55 is provided at the other end of the hose 57. Further, an extension pipe 59 is provided to connect the suction tool main body 1 from the hand portion 58.
[0084]
The operation of the above configuration is as follows.
[0085]
In the vacuum cleaner in which the suction tool body 1 is set, dust collection and light cleaning work can be performed regardless of the surface to be cleaned.
[0086]
【The invention's effect】
According to the invention of claim 1 of the present invention, the auxiliary blade comes into contact with the bristle brush, thereby improving the apparent rigidity of the bristle brush and providing the peripheral blade separately from the auxiliary blade. This improves the force of pushing the pile from the front to the back when the rotating brush is rotating forward to improve the self-propelled performance and improve the dust collecting performance by strengthening the lifting force.
[0087]
In addition, the floor can be wiped with a bristle brush, and both the floor surface and the pile surface can be used.
[0088]
According to invention of Claim 2 of this invention, in the vacuum cleaner which set the suction tool main body of Claim 1, dust collection property and a light cleaning operation can be performed regardless of a to-be-cleaned surface.
