The dust collecting method of the electric vacuum cleaner includes a paper bag type in which a bag filter called a paper bag is attached to a dust collecting chamber, or a cyclone type which collects dust after vortex separation, but in the present invention, dust is used. The collection method is not limited to a specific manner and can be appropriately selected.

The hose body 101 is a soft body portion 102 having, for example, a flexible belly, a handle portion 103 for operating an electric vacuum cleaner 300 having an operation portion (not shown) for operating an input of the vacuum cleaner 300, and A rigid extension pipe portion 104 having a telescopic structure is formed, and an end portion of the soft body portion 102 opposite to the handle portion 103 is connected to the cleaner body 200 so as to be detachable.

The floor surface suction tool 100 is detachably attached to the end portion of the rigid extension pipe portion 104 of the hose body 101 opposite to the handle portion 103.

As shown in FIGS. 2 and 3, the main body casing 3 constituting the outer periphery of the floor surface suction tool 100 is constituted by the upper case 1 and the lower case 2, and has an elongated structure transverse to the traveling direction S. The connection pipe 4 provided with the connection portion 5 connected to the rigid extension pipe portion 104 at one end is connected so that the connection portion 15 formed at the other end portion is sandwiched by the lower case 2 and the upper case 1 so as to be tiltable. The end portion of the connecting portion 15 opposite to the connecting portion 5 is formed to communicate with the inside of the connecting portion 15 on the left side. The right pair of connecting cylindrical portions 15a and the connecting cylindrical portion 15a are sandwiched between the upper case 1 and the lower case 2 so as to be tiltable.

The surface of the lower tank 2 facing the surface to be cleaned G is provided in a suction port 14 for sucking the opening of the dust present on the surface G to be cleaned. The suction port 14 communicates with the two suction ports 14a and 14b that communicate with the connection cylindrical portions 15a and 15b, respectively. In the main body casing 3, the rotating brush 6 is attached so as to protrude from the suction port 14 provided in the lower casing 2 toward the surface to be cleaned G, and is supported at the both ends thereof by the bearing portion 10, which will be described later, at the suction port 14.

Further, in order to prevent the dust that has not been sufficiently sucked by the rotating brush 6 from escaping to the outside, a shielding member 23 composed of a raised fabric for blocking a part of the outer circumference of the suction port and for increasing the degree of vacuum of suction is provided.

Next, the switch-use wheel 13 is placed in the lower case 2 so as to protrude toward the surface G to be cleaned. The switch-use wheel 13 is pivotally supported in the lower case 2, and is most prominent in a state in which the floor surface suction tool 100 is floated from the surface G to be cleaned. If the floor surface suction tool 100 is to be placed on the surface G to be cleaned, it is first contacted with the surface G to be cleaned, and is completely placed in the lower case 2 in such a manner that one part of the wheel remains.

A switch (not shown) that rotationally drives the rotary brush 6 in conjunction with the inflow is disposed in the main body casing 3 so as to be housed in a switch holding portion 20 to be described later, and the floor surface suction tool 100 is placed on the surface G to be cleaned. When the switch-use wheel 13 is in the state of being in the lower case 2, the switch (not shown) is turned on, and when the floor surface suction tool 100 is lifted from the cleaning surface G and the switch-use wheel 13 is protruded. The switch (not shown) is turned off, without causing the rotating brush to vacate vainly, and the user's hand is not accidentally caught in the rotating brush of the drive.

Next, the configuration of the floor surface suction tool 100 will be described. As number 5 As shown in the figure, a motor 16 (not shown) for accommodating a driving portion for rotationally driving the rotating brush 6 and a switch holding portion 20 for a switch (not shown) for driving the rotation of the rotating brush 6 described above are housed. It is equipped in the lower box 2.

As shown in Fig. 7, the motor 16 is coupled to the gear 18a by the first connecting belt 17, and is integrally formed coaxially with the gear 18a. The gear 18b having fewer teeth than the gear 18a is coupled to the second connecting belt 19 and When the bearing portion 10 holding the rotating brush 6 is coupled and the motor 16 is driven, the driving force is transmitted to the bearing portion 10 supporting the rotating brush 6 via the gears 18a and 18b, and the rotating brush 6 is rotated.

Next, the configuration of the rotating brush 6 will be described based on Fig. 8 . Fig. 8 is an external view of a rotating brush of a floor surface suction tool of the electric vacuum cleaner according to the first embodiment of the present invention.

(installation)

As shown in Fig. 9, the rotating brush 6 is inserted and attached from the side surface of the floor surface suction tool 100. As shown in FIG. 10, the opening portion 29 for attaching the rotating brush 6 is formed on one side surface of the main body casing 3, the concave portion 30 is provided around the opening portion 29, and the convex shape 31 is provided in the concave portion 30. As will be described later, in a state in which the rotating brush 6 is inserted from the opening 29 and locked to the attachment position of the floor surface suction tool, the outermost end portion of the rod 7a is located at the opening ratio in the removal direction of the rotating brush 6. The depth of the concave portion 30 is set such that the outermost end portion of the side surface of the main body casing 3 of the portion 29 is located further inside.

Inside the opening portion 29, a dust remover 11 for removing the dust removing means that entangles the rotating brush 6 is provided. As shown in Fig. 12, the dust remover 11 is made of a resin, and has a hollow portion 34 having a hollow annular shape with a notch, and the projections 33 extending in the axial direction of the rotary brush 6 are provided at equal angles in the circumferential direction. The position of the projection 33 corresponds to the position of the five groove portions 25 of the rotating brush 6, and is in the gap between the brush 27 (cleaning body) of the rotating brush 6 or the groove portion 25 between the cleaning body holding portions 24b. The state is guided in the axial direction of the rotating brush 6. Each of the projections 33 has substantially the same shape as the gap between the brush portions 27 of the cleaning member that rotates the brush 6, or the groove portion 25 between the adjacent cleaning body holding portions 24b, and has a gap with the valley portion. The upper surface of the facing surface is inclined from the front end toward the root in a direction away from the cylindrical base body 24.

Among the five projections 33, the inclined portion 33b on the upper surface of the projection 33 at the upper end is fixed to the projection 33 by pressing the metal blade 33c from the front end to the root of the projection 33. The blade 33c is fixed to the front end of the protrusion 33 It is inclined toward the root in a direction away from the cylindrical base body 24. Further, the shape of the blade 33c may be formed to be folded back into a V shape (valley shape) from the front end to the root portion. By forming the blade 33c with a material different from the protrusion 33, the durability of the blade 33c is improved, and the effect of reducing the wear of the blade 33c is obtained. Further, since the fixed blade 33c is press-fitted, even if the blade 33c is different from the protrusion 33, it can be manufactured and can be firmly fixed. Further, the method of installing the blade 33c is not limited thereto, and the blade 33c and the protrusion 33 may be formed of the same material. It can be integrally formed, and has the advantage of reducing manufacturing costs. Further, the brush 27 is cut so that the inner diameter of the dust remover 11 is smaller than the outer shape of the brush 27 provided in the rotary brush 6, and is in the vicinity of the hairline.

The dust remover 11 is held by the upper case 1 and the lower cover R9, and is fixed to the floor surface suction tool 100. Further, the dust of the dust remover 11 except the rotating brush 6 is removed. The removal of dust will be detailed in the description of the removal of the latter paragraph.

As shown in Fig. 9, when the rotating brush 6 is to be inserted from the opening portion 29, the rotating brush 6 passes through the hollow portion 34 of the dust remover 11, as shown in Fig. 11(a), and is provided to the cylindrical base body 24 of the rotating brush 6. The groove portion 25 is fitted into the projection portion 33 of the dust remover 11, and the projection portion 33 is fitted to the deepest portion of the groove portion 25. The brush 27 is provided between the protrusions 33.

As shown in Fig. 11, when the rotating brush 6 is gradually pushed in, the guide opening 26a provided in the guide portion 26 of the rotating brush 6 is held by the lower case 2 and the lower cover L8 as shown above and is screwed. The bearing portion convex portion 10a of the fixed bearing portion 10 is fitted and supported, and both ends of the rotating brush 6 are supported by the dust remover 11 and the bearing portion 10.

The bearing portion convex portion 10a is formed on the circumference as shown in Fig. 11(a) The direction is divided into 5 wedge shapes. Since the guide opening 26a is also an opening that is equally divided into five in the circumferential direction as shown in FIG. 8, the driving force of the motor 16 transmitted to the bearing portion 10 is surely transmitted to the rotating brush 6, and Rotate so that no idling occurs.

Here, before the guide opening 26a provided in the guide portion 26 of the rotating brush 6 is fitted to the bearing portion convex portion 10a, the surface of the protruding portion 33 opposed to the cylindrical base body 24 is set to be in the circle of the rotating brush 6. The tubular portion 24a. As a result, the rotating brush 6 does not lock with the protruding portion 33, and is rotatably rotatable about the central axis of the rotating brush 6. Therefore, even if the guide opening 26a is displaced around the central axis of the rotating brush 6 with respect to the bearing portion convex portion 10a, the rotating brush 6 is rotated as the rotating brush 6 is pushed, and the fitting of the two is facilitated.

Further, since the rotating brush 6 is disposed between the dust removing means 11 and the cleaning body holding portion 24b when the rotating brush 6 is attached to the main body casing 3, the dust is entangled in the rotating brush 6 during the sweeping. The side of the dust removing means 11 is also caught by the convex portion 24c, and can be prevented from moving over the convex portion 24c to the dust removing means 11. Therefore, it is possible to prevent the rotating brush 6 from rotating due to the dust being entangled with the dust removing means 11.

To end the insertion of the rotating brush 6 into the body casing 3, as shown in Fig. 15(a), the guide recesses 38a, 38b provided in the body casing 3 and the locking tabs provided on the grip portion 7 are aligned. When the position of 28 is inserted later, as shown in Fig. 14(a), the rod 7a comes to the position before installation.

However, in this state, only the rotating brush 6 is located at the mounting position, and is not yet fixed. As shown in Fig. 13(a), the grip portion 7 protrudes from the side surface of the body casing 3. This is because the grip portion 7 of the rotating brush 6 is as shown in Fig. 16(a). The cylindrical portion 24a is biased outward from the main body casing 3 by a biasing means 39 composed of an elastic body in the shape of a spiral spring, whereby the grip portion 7 is more easily gripped by the protrusion. Moreover, by highlighting, the user can visually understand that the installation is not finished.

In order to fix the rotating brush 6, the grip portion 7 is pushed further to the position where the rod 7a is in contact with the recess 30 under the biasing force against the biasing means 39 (the state of Fig. 13(b)), as shown in Fig. 14(b). ), the rod 7a is moved to the mounting position side (the state of Fig. 13(c)).

Then, as shown in Fig. 15(b), the locking tab 28 of the grip portion 7 is fitted into the groove-shaped locking portion 32 shown in Fig. 10, and is in a state in which the rotating brush 6 is fixed and cannot be taken out from the position. . In this manner, in a state where the rotating brush 6 is inserted from the opening portion 29 and locked to the mounting position of the floor surface suction tool, the outermost end portion of the rod 7a is located at the opening portion 29 in the removal direction of the rotating brush 6. The depth of the concave portion 30 is set such that the outermost end portion of the side surface of the main body casing 3 is further inside. Therefore, the locking of the rotating brush 6 is not erroneously canceled by sweeping the collision rod 7a such as furniture or a wall, and a floor surface suction tool having excellent usability is obtained.

Further, the convex shape 31 provided in the concave portion 30 is located between the mounting position where the rod 7a is moved and the position before mounting, since the convex shape 31 is in a state of moving (rotating) the rod 7a toward the mounting position side, the rod 7a is from the nearest The position of the recess 30 of the main body casing 3 is protruded, so that the rod 7a comes into contact with the convex shape 31 and passes over with resistance, and passes over to the mounting position.

Therefore, since the convex shape 31 becomes a resistance when the rod 7a moves to the detached position, the movement of the rod 7a to the accidental detachment position due to the convex shape 31 is suppressed, and it is difficult to fall off. This will end the installation.
