BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device for a vacuum cleaner having a rotating brush.

[0002]

2. Description of the Related Art Conventionally, this type of suction device for a vacuum cleaner has
The configuration was as shown in FIGS. Hereinafter, the configuration will be described.

As shown in the drawing, the suction tool main body 1 is formed by connecting an upper body member 58 and a lower body member 59 forming outer shells. Further, when the suction tool main body 1 is moved to clean a wall,
The suction tool main body 1 may hit a wall, and the bumper 60 for buffering an impact when hitting the wall is attached to the upper main body member 5.
8 and the lower main body member 59.

The suction tool main body 1 has a built-in rotary brush 2 which rotates counterclockwise as shown in the drawing for forcibly releasing dust adhering to a surface to be cleaned such as a carpet, and has a bottom opening with a lower opening. A suction port 69 is provided, and a connection pipe 3 communicating with a cleaner body (not shown) is rotatably connected to a rear portion. Brush bristles 4 are implanted on the outer peripheral surface of the rotating brush 2, and an electric motor 5, which is a driving source of the rotating brush 2, is mounted on the shaft of the electric motor 5, and a planetary gear that reduces the rotation and transmits the rotation to the rotating brush 2. It incorporates a gear 6 and a support member 7 disposed between the electric motor 5 and the planetary gear 6.

A reinforcing member 68 is attached along the upper surface of the upper body member 58 facing the suction port 69 at a distance of about 10 mm from the left and right end surfaces of the upper body member 58 in the longitudinal direction. In addition, the reinforcing member 68 is attached to a location away from the front end surface of the suction tool main body 1. The reinforcing member 68 is attached to the upper main body member 58 by welding or the like, and is made of a transparent member or the like.

The support member 7 is fixed to the electric motor 5 by a plurality of screws 8, and a groove 9 is formed on an end face of the support member 7, which is in contact with the electric motor 5, to improve ventilation through cooling holes provided in the electric motor 5. And the other end face is the inner ring 10 of the planetary gear 6.
And covers the surface of the planetary gear 6. In addition, a key groove (not shown) is provided on the inner peripheral surface of the rotating brush 2, and a convex portion (not shown) projecting from the outer ring of the planetary gear 6 is fitted into the key groove, and a concave portion is formed. The cooling air flow path is formed in the axial direction. A lid 12 having a bearing 11 is attached to the opening at both ends of the rotating brush 2.

The fixed shaft 13 is formed in a hollow shape, one end of which is protruded to the side of the rotary brush 2 to rotatably support the rotary brush 2 via a bearing 11 and to connect a lead wire connected to the electric motor 5 to the hollow portion. The other end is formed in a cylindrical shape and disposed inside the rotating brush 2 to support the outer periphery of the electric motor 5. The fixed covers 14 are attached to both ends of the rotating brush 2 to prevent dust from entering the rotating brush 2 and the bearing 11.

The rotary brush 2 is supported in the suction tool main body 1 via the fixed cover 14 and the fixed shaft 13, and a rotary brush 2 is provided at a substantially central portion of the rotary brush 2 facing the intake port 15 of the connection pipe 3. A plurality of ventilation holes 16 communicating between the inside and the outside of 2 are formed. The leak holes 17 allow the outside air for cooling the electric motor to communicate with the inside of the rotary brush 2 through the hollow portion of the fixed shaft 13, and are formed in a plurality on the side surface of the suction tool main body 1.

The operation of the above configuration will be described. An upper body member 58 and a reinforcing member 68 as outer shells, a lower body member 59,
The bumper 60 holds the rotating brush 2 in rotation and protects the rotating brush 2 from falling and collision. The reinforcing member 68 and the upper body member 58 protect the rotating brush 2 against impact from the upper surface, and the upper body member 58, the lower body member 59, and the bumper 60 protect the rotating brush 2 against impact from the front.
In particular, when an impact is received from the front, the upper body member 58
Deforms the space in which the rotating brush 2 is rotationally driven. This deforms in order to prevent the upper body member 58 and the like, which are protection members, from being broken by impact.

Next, when electricity is supplied to the suction tool main body 1 and the cleaner main body, the electric motor 5 rotates, and the rotational torque is increased while being reduced by the planetary gear 6 and transmitted to the rotary brush 2.
The dust attached to the carpet or the like is scraped out by the brush bristles 4, and the scraped-out dust is sucked into the cleaner body. At this time, only the planetary gear 6, the rotating brush 2, the lid 12, and the outer ring of the bearing 11 are rotated by the electric motor 5, and the electric motor 5, the fixed shaft 13, the fixed cover 14, and the lead wire are connected to the suction tool main body 1. Fixedly held.

When the cleaner body is operated, a negative pressure is applied to the space surrounded by the suction tool body 1 and the floor surface, and outside air flows in from the outer periphery of the suction tool body 1 so that the suction port 15 of the connection pipe 3 is opened.
, And the dust on the floor is also sucked into the air inlet 15 by this air flow.

At this time, since a negative pressure also acts on the vicinity of the ventilation hole 16 inside the rotary brush 2 through the ventilation hole 16 provided opposite to the suction port 15, the suction tool is inserted through the hollow fixed shaft 13 and the leakage hole 17. A pressure difference is generated between the outside of the main body 1 and a side portion of the rotating brush 2 that is communicated with the outside, and the outside air flows into the inside of the rotating brush 2 through the hollow portion of the fixed shaft 13 through the leak hole 17 and rotates. A recess 2a provided around the electric motor 5 of the brush 2
, And flows toward the air hole 16, and flows out from the air hole 16 toward the air inlet 15 having a lower pressure than the inside of the rotating brush 2 to cool the electric motor 5.

[0013]

In such a conventional structure, the most susceptible to impact during use of the vacuum cleaner is from the front surface of the suction tool main body, and the outer shell is easily deformed by the impact. Yes, every time an impact is applied, the space where the rotating brush is driven is deformed, the surrounding space for sucking dust of the rotating brush is difficult to maintain in a constant space, and the upper body member and the lower body member are deformed. Since the center of the drive shaft of the rotating brush held by the outer parts of the shaft is shifted, the rotation force of the rotating brush becomes unstable due to the load received by the shift of the shaft center, and the rotation speed for collecting dust fluctuates. Cheap. Due to this phenomenon, there is a problem that the dust suction capability and the dust collection capability of the suction tool main body are changed, and the dust removal performance is reduced.

The reinforcing member that receives an impact from the upper surface of the suction tool main body is a separate component that is structurally attached to the upper surface of the upper main body member, and has no series of design relevance with the upper main body member. Since it is necessary to change the shape in order to improve the design, a large number of dies are required, and there is a problem of changing for each model.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a suction device for a vacuum cleaner having stable performance and superior design.

[0016]

In order to solve the above-mentioned conventional problems, a suction device for a vacuum cleaner according to the present invention comprises an upper body member connected to a lower body member having a suction opening on the lower surface. In the suction chamber formed by the suction tool body and the suction tool body,
A suction tool for a vacuum cleaner, comprising: a rotary brush rotatably disposed so as to face the suction port; and a reinforcing member provided so as to overlap the upper body member from the front end of the upper body member to the upper surface thereof. It is what it was.

[0017] With this arrangement, the reinforcement member, the upper body member, and the lower body member receive a shock from the front of the suction tool main body, that is, the front body member, whereby the rigidity of the suction chamber and the rotary brush at the center of the rotating shaft is strengthened and bent. By making it difficult, the gap between the outer periphery of the rotating brush and the inner wall of the suction chamber is kept constant, so that the suction air generated around the rotating brush is stabilized, and the amount of fluctuation around the rotating shaft is reduced, so that the rotating brush is rotated. By stabilizing the number and the ability to scoop up dust, the suction performance and dust collection ability of the suction tool main body can be stabilized, and the dust removal performance can be improved.

Further, since the reinforcing member is provided from the front end portion of the upper main body member to the upper surface portion, it is difficult to identify the division between the reinforcing member and the upper main body member, and the ratio of the reinforcing member to the upper main body member is large. As a result, it becomes a series of design-like external parts, and can be deployed to other models with the same mold by changing the material or color of the reinforcing member, so that the suction tool main body is advantageous for many models.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows a suction tool main body for a vacuum cleaner according to Embodiment 1 of the present invention. FIG.
1 is an external perspective view of a vacuum cleaner to which a suction tool for a vacuum cleaner according to the present embodiment is connected.

The suction tool main body 18 has a built-in rotary brush 19 (see FIG. 1) for releasing dust adhering to a surface to be cleaned such as a carpet, and has a suction port 27 opened downward.
Also, as shown in the external perspective view of FIG.
A connecting body 21 connected to is rotatably provided. The cleaner main body 22 includes a dust collecting chamber 23 for collecting dust therein and an electric blower 24. A hose 26 connected to the extension pipe 20 is connected to a connection port 25 provided in the cleaner main body 22. The connecting body 21 of the suction tool main body 18 is configured to communicate with the connection port 25.

The suction tool main body 18 has an outer shell formed by connecting an upper main body member 61 and a lower main body member 62 via a bumper 63 formed of an elastomer or PP.
As shown in FIG. 2, a reinforcing member 64 provided along the surface shape of the upper main body member 61 is provided in the vicinity of substantially the center of the front part of the upper main body member 61 in the longitudinal direction (left-right direction) of the upper main body member 61.
To the left and right ends. Reinforcement member 64
Is provided so as to cover substantially the first half of the upper body member 61. At this time, the upper body member 61 and the reinforcing member 64
The molding is performed integrally by color molding. At this time, the upper body member 61 and the reinforcing member 64 are formed of the same material of a thermoplastic resin such as ABS. In addition, as another joining method of the upper body member 61 and the reinforcing member 64, there is a component joining method such as fitting and welding of claws or the like.

As shown in FIG. 1, the rotary brush 19 is rotatably provided in the suction tool main body 18 so as to face a suction port 27 opened on the lower surface of the suction tool main body 18. The rotary brush 19 is provided with a plurality of brushes 29 constituting a dust scraping portion on an outer peripheral surface of a substantially cylindrical brush holder 28 formed of a thermoplastic resin such as ABS, polystyrene, polypropylene or the like.

The dust scraper may be a thin plate-shaped blade, a strip having a wiping effect (for example, a cloth strip), or a combination thereof as appropriate, in addition to the brush 29.

The inside of the brush holder 28 has substantially the same configuration as that already described in the conventional example, and the reference numeral 16 of the conventional example is indicated by reference numeral 50 in this embodiment.

The operation and operation of the suction device body for a vacuum cleaner constructed as described above will be described below. First, when the suction tool main body 18 collides with a wall or the like during the cleaning operation, the lower main body member 62 tends to deform due to the frame shape. At this time, the upper main body member 61 connected to the lower main body member 62 via the bumper 63 is similarly deformed. In many cases, the location where the suction tool main body 18 collides is the front portion, and at this time, the reinforcing member 64 provided on the upper main body member 61 also tries to deform at the same time. At this time, since the upper main body member 61 and the reinforcing member 64 are provided integrally, the thickness is approximately doubled, and the rigidity is almost four times higher than that of the upper main body member 61 alone. Hinder. For this reason,
The gap between the outer peripheral portion of the rotating brush 19 and the inside of the suction tool main body 18 is kept uniform, and a stable dust collection performance is achieved because the suction air flows stably. Although this is an explanation for a collision, the outer shell of the suction tool main body 18 is actually deformed or distorted even when the suction tool main body 18 is actually operated on a carpet having a high operation resistance. On the other hand, since the rigidity is improved, the deformation hardly occurs. In addition, when it collides with a pillar or the like, the amount of deformation is reduced, so that the fitted components such as inlays, claws, and bosses are not damaged, and the strength against destruction can be improved.

As described above, in this embodiment, the upper main body member 61 is reinforced by the reinforcing member 64 to enhance the rigidity of the front portion of the upper main body member 61 so as to be less liable to be bent. By improving the strength against collision and warping of the brush and reducing the warping, the gap between the outer periphery of the rotating brush 19 and the inner wall of the suction tool main body 18 is kept constant, so that the passage through which dust flows in can be secured and maintained. Can be stabilized. In addition, since the center of the rotating shaft also has less distortion, the number of rotations of the rotating brush 19 is stabilized, the dust collecting ability of the rotating brush 19 is stabilized, and the dust collecting ability does not decrease due to the impact of collision.

In addition, since it can be molded integrally, it can be produced at a lower cost than when a part is incorporated as a separate part. Further, since the materials are the same when discarded, there is no need to separate them, so that the decomposability can be simplified and the separation process at the time of disposal can be simplified.

Further, by providing the reinforcing member 64 from the front end of the upper body member 61, the reinforcing member 64 and the upper body member 61 are provided.
Is difficult to understand and the ratio of the reinforcing member 64 occupying the upper body member 61 is increased, so that a series of design-like external parts are obtained. By changing the material or color of the reinforcing member 64, the same mold is used. Because it can be expanded to models,
The suction tool body 18 can be deployed in many models.

Also, in the present embodiment, the suction device main body 18 and the cleaner main body 22
, The electric motor 30 incorporated in the rotating brush 19 rotates and drives the rotating brush 19 to rotate. At this time, a negative pressure is applied to a space surrounded by the suction tool main body 18 and the floor, and outside air also flows in from the outer periphery of the suction tool main body 18. I will go. Since a negative pressure also acts near the ventilation hole 50 of the brush holder 28 of the rotating brush 19, outside air flows into the rotating brush 19 through the hollow portion of the hollow shaft 42 from the suction hole 55 on the side surface of the suction tool. .

The flowing outside air generates cooling air that passes through the inside of the rotating brush and flows out of the ventilation hole 50, thereby cooling the internal components such as the electric motor 30 and the like.

(Embodiment 2) FIG. 3 shows the structure of a suction tool main body for a vacuum cleaner according to Embodiment 2 of the present invention. Since the configurations and operations of the suction tool main body and the rotary brush are substantially the same as those in the first embodiment, only different portions will be described, and other description will be omitted. The same reference numerals have the same configuration.

The difference from the first embodiment is that the reinforcing member 65
Is a point formed by a transparent colored member. Further, the user can use the rotating brush 1 from the upper surface of the reinforcing member 65.
9 so that the reinforcing member 6 can be visually recognized.
An opening 66 is provided in a part of the portion overlapping with No. 5.
Further, the opening area of the opening 66 is provided such that the ratio of the area of the area where the upper body member 61 and the reinforcing member 65 overlap other than the opening 66 is 4: 6 in this embodiment.
Further, a vent hole 50 provided in the outer peripheral portion of the brush holder 28 is provided so as to face the opening 66,
It can be easily recognized from the upper surface of the reinforcing member 65. The back surface of the upper body member 61 and the back surface of the reinforcing member 65 are provided such that the back surface of the reinforcing member 65 becomes a step 67 in the space 66.

The operation and operation of the suction device for a vacuum cleaner constructed as described above will be described below.

Since the reinforcing member 65 is transparent, it is possible to easily check the condition of the internal rotating brush 19 below the reinforcing member 65. Therefore, when dust or the like adheres to the ventilation hole 50 provided in the rotating brush 19, The user notices and can easily understand when to perform maintenance. for that reason,
Failure due to burning of the electric motor 30 can be prevented. Also, the flow velocity near the suction port 27 is high,
Large dust may be suddenly sucked, and the dust may be entangled with the rotating brush 19. At this time, in order to prevent the rotation brush 19 from being locked, a step 67 is provided on the top surface substantially near the center of the suction tool main body 18 to provide a space into which the suction air strongly flows, so that the dust can be smoothly sucked. become. In addition, the reinforcing member 65 is colored for visibility to prevent the user from seeing the inside extremely.

In each of the above embodiments, the rotary brush is driven to rotate by an electric motor. However, for example, dust that is provided in the rotary brush by air that flows into the suction chamber from outside the suction tool main body by the suction force of the electric blower. The present invention can also be applied to a suction device for a vacuum cleaner in which the rotating brush is driven to rotate by suction air by colliding with a scraping portion.

[0049]

As described above, according to the present invention, the impact from the front surface of the suction tool main body is received by the reinforcing member, the upper main body member, and the lower main body member, so that the rotation of the suction chamber and the rotating brush is achieved. By strengthening the rigidity of the center of the shaft, the gap between the outer periphery of the rotating brush and the inner wall of the suction chamber is kept constant, the suction air generated around the rotating brush is stabilized, and the fluctuation amount of the center of the rotating shaft is reduced. Since the number of rotations is stable and the dust is scooped up, the dust suction ability and dust collection ability of the suction tool main body are stabilized, and the dust removal performance can be improved.
