Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a suction port body for a vacuum cleaner that has a rotating cleaning body such as a rotating brush, and when the lid of the suction port body is opened, the rotation cleaning is performed. It relates to a safety mechanism that prevents the body from rotating and prevents fingers from touching the rotating rotating cleaning body.

(Prior art) Conventionally, a rotary brush is rotatably provided in a rotary brush chamber in a suction port body, and this rotary brush is driven by a turbine or an electric motor that is rotated by the suction airflow to scrape out dust from a carpet, etc. In addition, a suction port body for a vacuum cleaner is known that has a structure in which dust is sucked in from a dust suction port formed on the lower surface of the rotating brush chamber.

And, in the suction mouth body of this kind of vacuum cleaner,
If lint or hair gets wrapped around the rotating brush, its rotational force will decrease, so even if you try to remove the lint by inserting your finger into the dust suction port, the area of the dust suction port is not that large and the suction port itself Since it is located on the underside of the rotating brush, it takes time and effort to clean the rotating brush thoroughly and hygienically.

Therefore, a structure has been adopted in which an opening with a relatively large opening area is opened and closed by a lid on the top surface of the rotating brush chamber, and the rotating brush can be cleaned easily and hygienically through this opening. ing. However, if the rotating brush is rotating and the cover is opened, there is a risk that the rotating brush may come into contact with the rotating brush, and there is a risk of injury to the fingers.

Therefore, various safety mechanisms have been implemented or proposed that automatically weaken or stop the rotational force of the rotary brush when the lid is opened while the rotary brush is rotating.

For example, in a suction port whose driving source is a turbine, a leak hole is formed in the surface of the suction port that faces the turbine chamber and is brought into contact with and separates from the lid, and when the lid is opened, the intake airflow is passed through the leak hole. By leaking air, the speed of the airflow hitting the turbine is lowered and the rotational force is weakened. However, with this structure, it is difficult to close the leak hole with sufficient airtightness when the lid is closed. Since it must be held in the main body, frictional resistance increases, making it difficult to attach and detach. Further, this structure cannot be applied to a suction port body using an electric motor as a driving source.

On the other hand, for a suction port whose drive source is an electric motor, it is conceivable to provide a switch that opens the motor drive circuit in conjunction with the opening operation of the lid, and to have a structure that stops the electric motor at the same time as the lid is opened. . However, in this structure, a switch is added to constitute a safety mechanism, which increases the cost, and this structure cannot be applied to a suction port body using a turbine as a driving source.

In addition, for example, the rotation transmission belt stretched between the pulley fixed to the rotating shaft of the electric motor and the pulley fixed to the rotating brush may be made somewhat longer.
A separate roller is provided that is pressed against this belt to provide tension, and by moving the roller away from the belt in conjunction with the opening operation of the lid, the tension on the belt is loosened, causing a slip between the belt and the pulley. , a structure that weakens the transmission force is also considered. However, even with this structure, it is necessary to add members such as rollers, so there is a problem in that the cost is high.

(Problems to be Solved by the Invention) As described above, in the suction port body of a conventional vacuum cleaner provided with an opening for cleaning the rotating brush, the rotating brush is stopped in conjunction with the opening of the opening. If a safety mechanism is not provided, there is a risk that fingers, etc. may come into contact with the rotating rotating brush, and if the safety mechanism is configured with a leak hole or switch, it may cause damage to the suction port whose drive source is a turbine or the electric motor. A safety mechanism can only be applied to one of the suction ports used as a source, and furthermore, when the safety mechanism is configured with a switch or a roller, there is a problem that the number of parts increases and the cost becomes high.

The present invention aims to solve these problems, and can eliminate the risk of hands touching a rotating cleaning body such as a rotating brush regardless of the difference in drive source, and furthermore, To provide a suction port body for a vacuum cleaner that has a simple structure and is inexpensive.

(Means for Solving the Problems) The suction port body of the vacuum cleaner of the present invention has a rotating cleaning body chamber therein, a dust suction port opening at the bottom facing the rotating cleaning body chamber, and an opening opening upward. a rotational drive body provided in the suction port main body; a groove-shaped bearing portion formed in the suction port main body and having open surfaces facing each other;
a rotating cleaning body rotatably supported by a bearing held in the bearing portion and disposed in the rotating cleaning body chamber;
A rotation transmission belt stretched between the rotation shaft of the rotary drive body and the rotary cleaning body, and a lid body that is detachably provided on the suction port body and opens and closes the opening, the bearing The part is the first part provided in the suction port body.
an upper portion of the second restriction portion that restricts at least movement of the bearing toward the rotary drive body; is provided on the lid.

(Function) When the suction port body of the vacuum cleaner of the present invention opens and closes the opening for cleaning the rotating cleaning body of the suction port body, the first regulating portion and the second regulating portion of the bearing portion are closed. In this case, the rotary cleaning body is rotatably supported with the bearing of the rotary cleaning body being restricted from moving toward the rotary drive body, and a belt stretched between the rotary cleaning body and the rotating shaft of the rotary drive body. The rotary cleaning body is rotated by the rotary driving body through the rotary cleaning body. If the lid body is opened by mistake while the rotary cleaning body is rotating, the upper partial bearing provided on the lid body of the second regulating part of the bearing part is released and the rotary cleaning body is opened. Since the restriction on the movement of the rotary cleaning body toward the rotary drive body side is lifted, the belt tension causes the rotary cleaning body to move toward the rotary drive body side, the belt becomes loose, the rotation transmission is weakened, and the rotation of the rotary cleaning body decreases or stops. .

The upper second regulating part 81 provided on the lid body 26 cooperates with the lower second regulating part 80 provided on the suction port main body 1 to position the bearing 72 so that the bearing 72 of the rotating brush 66 However, when the lid 26 is removed from the opening 16, the positioning, or restriction, of the bearing 72 by the second restriction part 81 at the upper part is released, and the rotation is restricted. As shown in FIG. 3, the brush 66 is moved toward the electric motor 51 by the tension of a belt 87, which will be described later, and rotation is not transmitted to the rotating brush 66.

Furthermore, the width of the opening side opposite to both the bearing parts 78 and 82 is increased via a step part 84. Further, a regulating piece portion 85 is formed at the center of the lower part of these bearing portions 78 and 82. Note that both of these bearing portions 78 and 82 are slightly inclined upwardly and forwardly.

Both bearings 72 of the rotary brush 66 are supported by the two bearings 78 and 82 in a detachable manner and are prevented from rotating so as to be movable up and down. That is, the substantially square-shaped flange 73 of the bearing 72 is fitted into the bearing parts 78, 82 in a state where it abuts against the step part 84 of the bearing parts 78, 82, so that the bearing 72 It is prevented from rotating, and movement in directions other than the vertical direction is restricted. In this way, the rotating brush 66 is rotatably supported within the rotating brush chamber 9. Note that both ends of the rotating brush 66 are connected to oblong holding holes 86 formed in the partition walls 7 on both sides of the rotating brush chamber 9.
It is inserted into the shaft so that it can rotate freely and move up and down.

The pulley 69 of the rotating brush 66 located in the belt chamber 13 and the pulley 5 of the electric motor 51
5 and an endless timing belt 87 is stretched between them. In addition, as shown in FIG. 1, both pulleys 5
A straight line connecting the centers of 5 and 69 passes above the upper end of the second regulating part 80 at the lower rear side formed in the suction port body 1 forming the bearing part 82.

Next, the operation of this embodiment will be explained.

When cleaning, the suction port body is connected to the vacuum cleaner body via a hose, an extension pipe, or the like. At this time, when the connecting pipe 43 of the suction port body is fitted to the extension pipe, the connector 47 provided on this connecting pipe 43
is connected to a connector 91 provided on the extension tube, and the circuit inside the vacuum cleaner body and the circuit inside the suction port are electrically connected via a power supply line provided along the extension tube and the hose. That is, as shown in FIG. 7, one pole of the AC power supply 92 supplied through the vacuum cleaner body is connected to the
Diodes 93, 94, 9 that drive the electric motor 51
5, 96 and capacitors 97, 98, and the other pole of the AC power supply 92 is connected to the circuit board 49.
The rectifier circuit 100 is connected to the other input terminal of the rectifier circuit 100 through a fuse 101, a resistor 102, and a POSISTER 103 mounted on the rectifier circuit 100 in series.

During cleaning, the opening 16 of the suction port body 1 is closed by the lid 26, and in this state, as shown in FIG.
A second regulating part 80 on the suction port body 1 side and a second regulating part 81 on the lid body 26 side form regulating rear surfaces 80a and 81a facing the surface of the bearing 72 on the motor 51 side.
is in contact with. Further, a force is applied to the bearing 72 on the belt 87 side of the rotating brush 66 in the direction of the motor 51 due to the tension of the belt 87.
The regulation rear surfaces 80a, 8 of the second regulation parts 80, 81
1a, the belt 87 is kept under tension.

The rotational force of the electric motor 51 is then
The vibration is transmitted to the rotating brush 66 via a belt 87 stretched between a pulley 55 fixed to the rotary brush 66 and a pulley 69 fixed to the rotating brush 66, and the rotating brush 66 scrapes dust from the carpet. increase. This scraped up dust is sucked in from the dust suction port 15 of the suction port main body 1 by driving the electric blower inside the vacuum cleaner main body, and is sucked into the rotating brush chamber 9, the communication port 14, the ventilation chamber 11, the communication pipe 41, and the extension pipe. and is led to the dust collection chamber inside the vacuum cleaner body via a hose.

In addition, when removing dust entangled with the rotating brush 66 during cleaning, the electric motor 51 is normally stopped, the lid body 26 is opened, and the opening 16 is removed.
is opened, and the rotating brush 6 is inserted through this opening 16.
Clean 6. To open the lid 26, slide both knobs 31 as shown by the arrows in FIG. Remove the locking claw portion 27 from the engagement hole 21 of the suction port body 1. In addition, when closing the lid body 26, conversely, first insert the locking claw portion 27 into the engagement hole 21.
At the same time, the lower edge of the rear surface of the lid body 26 is engaged with the engagement step part 22 of the suction port body 1, and then both knob bodies 31 are slid and the locking grooves are aligned with the locking protrusion. By engaging with , the lid body 26 is locked to the suction port body 1 .

As described above, by providing the opening 16 of the suction port body 1, when the rotating brush 66 becomes tangled with lint, hair, etc. and becomes difficult to rotate, it can be removed from the dust suction port 15. Since the rotating brush 66 can be cleaned from the wide opening 16 located on the upper surface without putting your hands in it, extra effort is not required and it is sanitary.

In addition, if the cover body 26 is opened by mistake while the electric motor 51 is operating, the rotary brush 6
Rotation is not transmitted to 6. That is, when the lid body 26 is opened, the second regulating part 81 at the upper part of the lid body 26 that forms the bearing part 82 moves to the second regulating part 81 at the lower part of the suction port body 1.
As shown in FIG.
The movement of the bearing 72 of the rotating brush 66 toward the electric motor 51 is no longer restricted, and the tension of the belt 87 acts in a direction to reduce the center-to-center distance L between the rotating brush 66 and the rotating shaft 54 of the electric motor 51. As a result, the center-to-center distance L decreases from L ₁ to L ₂ (L ₁ > L ₂ ), as shown in Figure 3.
The bearing 72 can be removed from the bearing portion 82. In this state,
Since the belt 87 becomes loose and the rotational transmission force is weakened,
The rotating brush 66 stops.

In this embodiment, since the belt 87 is a timing belt, sometimes the belt 87 disengages from the gear-shaped pulley 69 of the rotating brush 66, and the rotating brush 66 comes to a complete stop. Furthermore, even if the rotating brush 66 does not completely stop, its rotational force has weakened, so a light touch will stop the rotating brush 66.

Therefore, since there is no need to touch the rotating brush 66 while it is rotating, there is no risk of injury and it is safe.

Moreover, since members such as rollers and switches are not added to construct such a safety mechanism, the structure is simple and inexpensive.

Furthermore, when reattaching the lid 26, the bearing 72 that has come off is fitted into the bearing portion 82, and then the lid 26 is closed.
Even if the upper second regulating part 81 forming the regulating part 81 is provided on the lid 26, the lower second regulating part 80 forming the regulating rear surface 80a is provided on the suction port main body 1. 26 is removed, the lower part of the bearing part 82 in the suction port main body 1 forms a substantially U-shaped groove on the side surface. Since the bearing 72 is not dislocated, the lid 26 can be easily reattached.

Further, the corner portion of the flange portion 73 of the bearing 72 is the circular arc portion 7
4, and the upper end of the second restriction 80a at the bottom of the bearing part 82 also forms an arcuate part 83 that smoothly continues to the arcuate part 74, so that the bearing 72 may be slightly shifted. Even if the bearing 72 is not completely fitted into the bearing 82, when the lid 26 is attached, as the bearing 72 is pushed by the second restriction part 81 on the upper part of the lid 26, both arcuate parts 74, The bearing 72 is reliably fitted into the bearing part 82 by the guide 83.

Furthermore, since the outer circumferential shape of the flange 73 of the bearing 72 that is fitted into the bearing 82 is approximately square, when the flange 73 is fitted to the bearing 82, each side of the flange 73 is There are four possible vertical and horizontal positional relationships, and therefore, there is no need to consider the orientation of the bearing 72 when holding the bearing 72 in the bearing section 82 when attaching the lid 26. At the same time, the attachment of the lid 26 and the accompanying fitting of the bearing 72 to the bearing portion 82 can be done reliably and easily.

Further, since the second regulating part 81 on the upper part of the lid body 26 formed by the bearing part 82 is provided near the locking part that locks the lid body 26 to the suction port body 1, the second regulating part 81 , it is difficult to deform and move, and the bearing 72 is reliably held. Note that even if the locking portion is not the knob 31, the bearing 72 can be held securely in the same manner. Also,
By providing the upper second regulating portion 81 at the bottom of the support recess 28 that holds the knob 31, the strength of the support recess 28 against the force applied by the knob 31 is increased, and the operation of the knob 31 is ensured. In addition, since the support recess 28 formed in the box shape has a certain degree of strength, the bearing 7
The strength of the upper second regulating portion 81 against the force applied by the second regulating portion 81 also increases.

Furthermore, if the lid body 26 is made of synthetic resin and the upper second regulating portion 81 is integrally formed with the lid body 26, sink marks are likely to occur in the portion where the second regulating portion 81 is formed. By providing the second regulating portion 81 at the bottom of the support recess 28 that supports the knob 31, the sink mark is hidden by the knob 31, so that the appearance is improved.

In addition, in the above embodiment, the rotary driving body is the electric motor 5.
1, the rotary drive body may be a turbine rotated by the suction airflow. In this case, in order to stop the rotating brush 66 when the lid body 26 is opened, there is no need to provide a leak hole that is difficult to seal.

Further, in the above embodiment, the second restricting portion 81 above the groove-shaped bearing portion 82 is provided on the lid 26, but the entire pair of front and rear first and second restricting portions forming the bearing portion are It may be provided on the lid 26, or if the bearing portion 72 is inclined upward and rearward, the front regulating portion may be provided on the lid. In short, at least a portion of the bearing portion where movement of the rotary brush 66 toward the rotary drive body is regulated may be provided on the lid body 26. However, as in the above embodiment, the second regulating part 81 of the bearing part 82,
In other words, if the surface on the electric motor 51 side is provided on the lid 26, the bearing 7 of the rotating brush 66 will be removed when the lid 26 is opened.
2 can be removed from the bearing portion 82 more reliably.

(Effects of the Invention) According to the present invention, among the bearing parts that support the rotary cleaning body driven by the rotary drive body via the belt, at least the second bearing part that restricts the movement of the rotary cleaning body toward the rotary drive body side is provided. The restriction part is provided on the lid body that opens and closes the opening for cleaning the rotary cleaning body, so even if the lid body is accidentally opened while the rotary cleaning body is rotating, the belt tension will prevent the rotary cleaning body from rotating. The rotation transmission is weakened by moving to the drive body side, and the transmission of rotation to the rotary cleaning body is stopped, making it safe to avoid touching the rotating cleaning body with fingers, and also preventing the drive source such as a turbine or electric motor from touching the rotating cleaning body. It can be applied regardless of the difference, and since there is no need to add new members to configure the safety mechanism, the structure can be simplified and the cost can be reduced.
